\section{Introduction}

Permanent magnets are of great technical importance for many key technologies such as electric vehicles, wind turbines, and automatisation and robotics to name only a few~\cite{gutfleisch_magnetic_2011}.
Looking at the intrinsic magnetic properties, such materials demand a large
magneto-crystalline anisotropy energy (MAE), a sizable saturation magnetization, and a high Curie temperature.
The MAE originates from the spin-orbit coupling (SOC) and sets an upper limit for the microstructure dependent coercivity of permanent magnets.
At present, rare-earth magnets based on Sm-Co (MAE: 17.0 MJ/m$^3$, Magnetization (M$_s$): 910 kA/m) and Nd-Fe-B (MAE: 5.0 MJ/m$^3$, M$_s$: 720 kA/m) are prototypes of high performance permanent magnets,
 with a substantial cost and performance  gap to other classes of commercially available permanent magnets such as AlNiCo (MAE: 0.04 MJ/m$^3$, M$_s$: 50 kA/m) and ferrites (MAE: 0.03 MJ/m$^3$, M$_s$: 125 kA/m)~\cite{coey_permanent_2012}.
Thus, there is a great interest to develop novel permanent magnets so that the full spectra of applications can be achieved,
ideally without critical elements such as rare-earth elements~\cite{jpd_current, Skokov-2018}.

An enlightening idea was proposed to achieve giant MAE in tetragonally distorted FeCo alloys~\cite{prl-feco-1},
where both the tetragonal distortion and fine tuning of the number of electrons by alloying are crucial for the enhanced MAE.
Follow-up experimental studies on FeCo alloys deposited on various substrates confirmed the theoretical prediction~\cite{prl-feco-pt}.
Nevertheless, due to the strong tendency for the FeCo alloys to relax, it is difficult to maintain the tetragonal distortion
induced by the underlying substrates for thin films thicker than 2 nm~\cite{prl-feco-pt, apl-91-262512-2007, prb-80-064415-2009}.
Recently, following the prediction based on DFT calculations~\cite{jap-116-213901-2014, j-physics-condensed-matter-27-476002-2015},
systematic studies have been performed on FeCo+X (X= C and B), where spontaneous tetragonal distortions
with c/a=1.04 can be induced by a few atomic percent interstitial  doping of C or B atoms occupying the octahedral interstitial sites.
The resulting MAE can be as large as
0.5 MJ/m$^3$ with B concentration up to 4 at\%, where the tetragonal strain reaches 5\%.
For Fe$_{0.38}$Co$_{0.62}$, a large interstitial concentration of 9.6 at\% B was achieved.~\cite{j-physics-condensed-matter-27-476002-2015}
The effect of light interstitials on the magnetic properties of body-centered cubic (BCC) iron has also been well studied.
$\alpha$-Fe with 12.5 at\% content of nitrogen interstitial has been grown by sputtering on the MgO (100) substrates, leading
to about 10\% tetragonal distortion and significant enhancement of magnetization and MAE~\cite{fe-n-k}.
First-principle calculations and experimental results show that Fe
with nitrogen interstitial has
sizable MAE, favoring perpendicular magnetization~\cite{fe-n-k}.
Using the molecular beam epitaxy, boron has been incorporated into bcc Fe as interstitial dopants, which give rise to tetragonal distortions but the resulting MAE still favors in-plane magnetization due to tendency for B atoms to be agglomerated~\cite{fe-b}, where the interstitial content of B atoms can be as high as 14 at\%.

Considering only the crystal structure, the austenite phase of Heusler alloys with the conventional cubic cell can be regarded as a $2\times2\times2$ supercell of the bcc lattice.
In this regard, light interstitials such as H, B, C, and N  can also be promising to induce significant tetragonal distortions and thus substantial MAE to Heusler alloys, like the FeCo alloys and bcc Fe.
It is noted that the Heusler alloys in the tetragonal martensitic phase do show significant MAE.
For instance, among 286
Heusler compounds, a systematic high throughput (HTP) screening
suggests 19 potential tetragonal systems with large out-of-plane MAE (as large as 0.9 MJ/m$^3$)~\cite{fprmheusler}.
Matsushita  {\it et al.} found 15 Heusler compounds have tetragonal distortions of which the MAEs ranges from -12 MJ/m$^3$ to 5.19 MJ/m$^3$~\cite{jpd-Matsushita}.
Focus on Ni based full Heusler compounds, Herper $et. al.$~\cite{ni-based} found tetragonal Ni$_2$FeGe has an MAE of 0.95 MJ/m$^3$,
which can be further increased to 1 to 2 MJ/m$^3$ by non-magnetic doping.
Furthermore, imposing strain by proper substrates is helpful to engineer a large MAE out of the cubic Heusler alloys.
It is found that the out-of-plane MAE of epitaxial Co$_2$MnGa (001) films can be remarkably enhanced from 0.11 MJ/m$^3$ to 0.33  MJ/m$^3$ by changing the substrate from  ErAs/InGaAs/InP  to ScErAs/GaAs~\cite{jmm-Michael-286-340-2005}.
Lastly, previous experiments have already demonstrated that interstitials can be incorporated into Heusler alloys, leading to enhanced mechanical stability and magnetocaloric effect~\cite{Scripta-Materialia-75-15-2014, apl-100-192402-2012}.
For  Ni$_{43}$Mn$_{46}$Sn$_{11}$C$_x$, when the interstitial content x is increased from 0 to 8 the martensitic phase transformation temperature is increased from  196 to 249 K,   while a remarkable increase of MAE is observed when x is increased from 0 to 2~\cite{Scripta-Materialia-75-15-2014}.
Due to large loss of manganese in content of x=8, there is even a distortion of crystal structure from Hg$_2$CuTi-type to the Cu$_2$MnAl-type~\cite{Scripta-Materialia-75-15-2014}.
Similar effect has also been observed in Ni$_{50}$Mn$_{34.8}$In$_{14.2}$, Ni$_{43}$Mn$_{46}$Sn$_{11}$ and Ni$_\text{50}$Mn$_\text{38}$Sb$_\text{12}$ doped with B interstitial~\cite{apl-100-192402-2012, apl-92-102503-2008, MSE-B-176-1322-1325-2011}.

Furthermore, previous experiments have also demonstrated that interstitials can be incorporated into Heusler alloys, leading to enhanced mechanical stability and magnetocaloric effect~\cite{Scripta-Materialia-75-15-2014, apl-100-192402-2012}, $i.e.$, the famous magnetostructural first order transformation candidates off-stoichiometric Ni-Mn-In, Ni-Mn-Sn and Ni-Mn-Sb based Heusler alloys. Surprisingly, I.~Dubenko $et. al.$~\cite{apl-100-192402-2012} found incorporated one B atom interstitial to Ni$_{50}$Mn$_{34.8}$In$_{14.2}$, the phase transition temperature is increased to above room temperature as 320 K.
In a more systemic research~\cite{Scripta-Materialia-75-15-2014}, for Ni$_{43}$Mn$_{46}$Sn$_{11}$C$_{x}$, the martensitic phase transformation temperature are found to increase from 196 to 249 K   with respect to the content x for interstitial C increasing from 0 to 8. Further,  the magnetic entropy has a significant change from 27.4 Jkg/kg$^{-1}$ to 34.6 Jkg/kg$^{-1}$ when  x is increased from 0 to 2, while that values are slightly decreased to 21.3 Jkg/kg$^{-1}$ and 17.1 Jkg/kg$^{-1}$ for x=4 and x=8.
Moreover, due to large loss of manganese in content of x=8, there is a distortion of crystal structure from Hg$_2$CuTi-type to the Cu$_2$MnAl-type~\cite{Scripta-Materialia-75-15-2014}.
Such similar increase of martensitic phase transformation temperature and similar change of  magnetic entropy are also observed for  Ni$_{43}$Mn$_{46}$Sn$_{11}$B$_x$ (x=0, 1, 3, and 5)~\cite{apl-92-102503-2008}.
For Ni$_\text{50}$Mn$_\text{38}$Sb$_\text{12}$, when the content of B interstitial atom increasing from 1 to 5, the paramagnetic-ferromagnetic austenitic transition are increased while that of the ferromagnetic-antiferromagnetic martensitic transition temperature tends to decrease~\cite{MSE-B-176-1322-1325-2011}.

In this work, focusing on developing rare-earth free permanent magnets, we have performed high-throughput first-principles calculations to investigate the
effects of light interstitials ({\it e.g.}, H, B, C, and N) on cubic Heusler alloys.
After identifying the most favorable site preference of the interstitial atoms,  the MAE of compounds with negative formation energy
was evaluated to select the most promising candidates. Apart from thermodynamically stable  criteria, the disorder effect should also be considered, which is however beyond the scope of the present paper and saved for future study.
We observed that the induced MAE can be as large as 2.4~MJ/m$^3$, and there are 32  systems with a sizable out-of-plane MAE (> 0.4~MJ/m$^3$).
Detailed analysis based on the Bain path and the atom-resolved MAE reveal that not only the global tetragonal distortion
but also the associated local chemical bonding are crucial for the interstitial induced magnetic anisotropy.

\section{Computational details}
\label{comdetail}

Starting with 128 full
Heusler alloys with space group Fm$\bar{\text{3}}$m including at least one of magnetic atoms Cr, Mn, Fe, Co, and Ni from the Inorganic Crystal Structure Database (ICSD)~\cite{icsd} (cf.
Table~\ref{tables1} in Appendix~\ref{appendx}),
we performed density functional theory (DFT) calculations firstly to identify the energetically most favored interstitial sites for H, B, C, and N atoms.
There are four types of interstitial sites based on the symmetries, as shown in Fig~\ref{fig:1}(a). The DFT calculations are managed with our in-house developed high-throughput environment (HTE)~\cite{hte1,hte2},
using both the Vienna ab initio Simulation Package (VASP)~\cite{vasp1,vasp2} and full-potential local-orbital (FPLO)~\cite{fplo1,fplo2} codes.
The structure optimization is performed in a two step manner.
Firstly, ultrasoft pseudopotentials (US-PP)~\cite{chaoyan} are used in combination with the PW91~\cite{vasp3}  exchange correlation functional,
where the cutoff energy for the plane wave basis is set to 250 eV and and a k-mesh density of 30\AA$^{-1}$.
Secondly, the structure is relaxed  using the projector augmented plane wave (PAW) method with the exchange-correlation functional under
the generalized gradient approximation (GGA) parameterized by Perdew, Burke, and Ernzerhof (PBE)~\cite{vasp4} with increasing plane
wave expansion as 350 eV and $k$-mesh density as 40 \AA$^{-1}$ to achieve good convergence.
After obtaining the energy lowest configuration, the MAEs of candidates with negative formation energy are calculated by using FPLO with a $k$-mesh density of 120 \AA$^{-1}$ to guarantee
fine convergence.  For the MAE calculations of Ni$_2$FeGa with C interstitial, the resulting $k-$mesh is set as $24\times 24\times 17$.
The bonding analysis is done in terms of the crystal orbital Hamilton population (COHP) evaluated using the LOBSTER code~\cite{cohp}.

\section{Results and discussions}

As shown in Fig.~\ref{fig:1}(a), the systems we considered correspond to doping 6.25 at\% interstitial atoms (I) into the full Heusler alloys (X$_2$YZ), leading to a general chemical formula X$_2$YZI$_{1/4}$.
This is in accordance with the typical doping concentrations experimentally accomplishable, $e.g.$, 12.5 at\% content of N in Fe and 9.6 at\% of B in Fe$_{0.38}$Co$_{0.62}$. ~\cite{j-physics-condensed-matter-27-476002-2015, fe-n-k}
Like Fe-Co alloys, we find light interstitials can indeed cause stable tetragonal distortion to cubic full Heusler alloys, which is quantizated by the c/a ratio between the c-axis and in-plane lattice constants.
As shown in Table~\ref{table1}, with N interstitials, Fe$_2$NiAl has the a tetragonal distortion as large as c/a=1.57.
Such strong tetragonal distortions prevail in the other Heuslers with the other types of interstitial atoms, which break the cubic symmetry and hence lead to possible significant MAE.
From the theoretical point of view, the MAE is defined as the total energy difference between the magnetization directions parallel to [100] (in-plane) and [001] (out-of-plane)
directions as
\begin{equation}
\label{eqm}
\text{MAE}=E_{[100]}-E_{[001]}
\end{equation}
where $E_\alpha$ is the total energy when magnetization direction is parallel to
${\alpha}$.
When the MAE value is positive (negative),  the spontaneous magnetization will lie in the out-of-plane (in-plane) direction.
Nevertheless, not all the interstitials are thermodynamically stable, as indicated by the formation energy.
The candidates with an MAE more than 0.4 MJ/m$^3$ and a negative formation energy are listed in Table~\ref{table1}.

We notice all the parent Heusler compounds listed  in Table~\ref{table1} are ferromagnetic apart from Mn$_2$VGa and Rh$_2$NiSn.
In our high throughput calculations, for convenience, all Heusler compounds are assumed to be ferromagnetic (FM).
Previous studies~\cite{RH2MNAL-JPD,RH2MNAL-PRM} have shown Rh$_2$MnAl is an antiferromagnet with Mn are antiferromagnetic coupling between nearest neighbors in the (111) plane,
which is still in the same antiferromagnetic phase after incorporating C or N interstitials.

 As to Mn$_2$VGa, experimental research~\cite{jmm-mn2vga}  has shown it is a half-metallic ferrimagnet with antiferromagnetic coupling between Mn and V with a total net saturation  magnetization  per formula unit as 1.88 $\mu_{\rm B}$ at 5 K. After inducing interstitial (C, B or N),  Mn$_2$VGa is still ferrimagnettic with antiferromagnetic coupling between Mn and V, although initial spin configuration is ferromagnetic.  Mn$_2$VGa have large MAE values as 1.82 MJ/m$^3$, 1.50 MJ/m$^3$ and 1.26 MJ/m$^3$ with B, C and N interstitial, respectively. However, due to the ferrimagnettic phase, the resulting magnetization densities for Mn$_2$VGa with B, C and N interstitial are as weak as about 0.04-0.05 $\mu_{\rm B}$/\AA$^3$. Among all listed compounds in Table~\ref{table1}, Rh$_2$NiSn is  weak ferromagnetic as experimental study~\cite{rh2nisn} suggests it has a magnetic moment 0.6 $\mu_{\rm B}$ per formula unit.  Our calculations demonstrate that H interstitials can induce a tetragonal distortion of c/a=1.26 and a sizable MAE value as 0.82 MJ/m$^3$, whereas the magnetization is only about 0.02 $\mu_{\rm B}$/\AA$^{3}$.

As shown in Table~\ref{table1}, we found 32 compounds with a large out-of-plane MAE (> 0.4 MJ/m$^3$)
 as well as 10 compounds with large in-plane MAE (absolute value larger than 0.4 MJ/m$^3$).
In general, the interstitial atoms prefer to be located at the octahedral centers (including both the 24f and 24g sites) except for the H interstitials in Au$_2$MnAl which is stable at the tetrahedral center.
For the cases of octahedral center, the interstitials mostly prefers 24f sites ($\frac{1}{4}$,0,0) where there are the same atoms in the plane perpendicular to the c-axis.
On the other hand, for Co$_2$FeAl with N, Au$_2$MnAl with N and C, Ni$_2$MnSn with B, C and N, interstitials prefer 24g sites ($\frac{1}{2}$,$\frac{1}{4}$,$\frac{1}{4}$).
We note that Fe$_3$Ge with H  interstitial has  the largest magnetization density as 0.13 $\mu_{\rm B}$ /\AA$^3$ as well as quite large MAE value (1.50 MJ/m$^3$),
 indicating it is a promising permanent magnet. Furthermore, comparing with the magnetization and MAE of experimentally realized permanent magnets~\cite{gutfleisch_magnetic_2011,mae-mag1,mae-mag2,mae-mag3,mae-mag4,mae-mag5}
 Heusler alloys with interstitials  can fill the gap between the low performance magnets (such as AlNiCo and ferrite) and high performance magnets (such as Sm-Co and Nd-Fe-B) in terms of MAE and magnetization, which can spread a wide spectrum of applications.

Interestingly, Au$_2$MnAl with H is the only candidate where the interstitials prefer the tetrahedral center (16e site).
 However, for cases of Au$_2$MnAl with N and and C, interstitial prefers to be located in the octahedral centers with in-plane  MAE.
  Such special interstitial behaviors can be easily understood based on the chemical bonding.
Intuitively, due to the large atomic spheres of Au atoms,  there is more space between the tetrahedron edge bound than the other Heusler compound.
For instance, in Au$_2$MnAl with H, the bond length of H-Au pair in  tetrahedral center (1.83 \AA) is comparable with that in octahedral center (1.93 \AA).
On the other hand, the bond length of Cu-H pair for Cu$_2$MnAl with H in tetrahedral center is just 1.62 \AA,
 of which the value is obviously smaller than the H-Au pair for H interstitial in the tetrahedral center of Au$_2$MnAl (1.83 \AA).
 This suggests Au atom can really provide more space for interstitials in the tetrahedral site.  It should be noticed that  Cu-H pair in octahedral center also has a bit larger bond length (1.70 \AA) than that in tetrahedral center.
 However, in the tetrahedral center case, the bond length is too small to provide enough space for the interstitials.
  Thus, the H interstitials prefer the octahedral  centers in Cu$_2$MnAl.
On the other hand, for Au$_2$MnAl with C and N, it is observed that the interstitial atoms still prefer the octahedral center because of the larger atomic radii of  C and N atoms compared to that of H.

Therefore, in order to get the interstitials incorporated at the tetrahedral center, two conditions should be satisfied: (a) The interstitial atoms should be small; (b) There should be large atoms in the parent compound, providing more space.
Different site preference of the H and C/N interstitials induces significant changes on the MAE of Au$_2$MnAl, {\it e.g.}, H-interstitials favor out-of-plane magnetization while C/N interstitials lead to in-plane magnetization.

According to Table.~\ref{table1}, Fe$_2$CoGa with interstitials is a promising candidate for permanent magnets. However, in the ICSD database~\cite{icsd}, Fe$_2$CoGa (ICSD ID: 102385 and 197615) and Fe$_2$CoGe (ICSD ID: 52954) are in the full Heusler structure, while early M\"ossbauer measurements have shown Fe$_2$CoGa and Fe$_2$CoGe are energetically favored in the inverse Heusler structure~\cite{res1, fe2coge}.
Previous theoretical study~\cite{res2} found that full Heusler Fe$_2$CoGa have
a martensitic phase transition with a c/a ratio as  1.4, which is also confirmed by our calculation (cf. Fig.~\ref{path}(a)).
 According to our Bain-path calculations,  the inverse Heusler structure is still more energetically favored for Fe$_2$CoGa, even after considering H, B, C, and N interstitials.
Nevertheless, after introducing interstitials, for the full Heusler structure,  the c/a ratio is near to 1.4; whereas for the inverse
 Heusler structure, the c/a ratio of Fe$_2$CoGa with interstitials is just from 1.1-1.2 due to there is no metastable phase (Fig.~\ref{path}(a)).
The MAE values of the  inverse Fe$_2$CoGa with  B, C, N, and H  interstitial  are 0.1026 MJ/m$^3$,  0.2148  MJ/m$^3$,  0.3798  MJ/m$^3$, and 0.1925 MJ/m$^3$, respectively. Such lower MAE values are partially due to that interstitials induce much weaker tetragonal distortion to Fe$_2$CoGa for inverse Heusler structure ($1.1\leq c/a \leq 1.2$) than  that for full Heusler structure ($1.45 \leq c/a \leq 1.5$).

More interestingly, C, N, and H interstitials induce significant MAEs to Ni$_2$FeGa.
 Experimental studies suggest that Ni$_2$FeGa can be grown by melt-spinning technique~\cite{apl-82-3-2003} or glass-purify method~\cite{JournalofCrystalGrowth-388-15-2014},  transforming from high chemical ordering L2$_1$ structure (full Heusler) to martensitic structure at 142 K with a  high Curie temperature of 430 K\cite{apl-82-3-2003}.
Further experiments showed polycrystalline alloys Ni$_{53+x}$Fe$_{20-x}$Ga$_{27}$ have  smaller but comparable  entropy changes as classical magnetocaloric Heusler alloy systems  Ni-Mn-Ga and Ni-Mn-Sn~\cite{apl-132503}.
DFT calculations suggest that Ni$_2$FeGa has a tetragonal (corresponding to the martensitic phase) structure of c/a=1.35~\cite{jap-111-033905-2012,ni-based} with  an MAE as 0.318 MJ/m$^\text3$~\cite{ni-based}. We also found that Ni$_2$FeGa  is stable in the tetragonal structure with a c/a ratio as 1.35 (Fig.~\ref{path}(b)) and a comparable MAE as 0.2334 MJ/m$^\text3$ (0.0698 meV per chemical formula cell).
 However, the energy difference between tetragonal and cubic structures is as small as 2.80 meV/atom. As proposed by Barman, the martensite phase transition temperature is proportional to the energy difference between cubic and martensite phases~\cite{Barman}, as manifested by the experimental martensitic transition at 142 K~\cite{apl-82-3-2003}.

 After inducing interstitial C, H, or N, Ni$_2$FeGa is stable in the tetragonal phase with $c/a\approx 1.40$.

Correspondingly, the MAEs have been enhanced to 1.43 MJ/m$^3$, 0.94 MJ/m$^3$, and 0.56 MJ/m$^3$ for Heusler Ni$_2$FeGa with N, C, and H interstitials, respectively.
Obviously, C and N interstitials cause more significant enhancement on the MAE than the H interstitials, though the resulting c/a ratios are comparable.
Therefore, we suspect that both the tetragonal distortion and the chemical bonding environment will influence the MAE values for Heusler with interstitial, which will be discussed in detail below.

Turning now to the origin of the induced MAE by interstitials, from the theoretical perspective, beside the shape anisotropy due to the magnetic dipole-dipole interaction,
the magneto-crystalline anisotropy (MCA) can be attributed to the spin-orbit coupling (SOC), which is the dominant contribution to MAE and hence coercivity for PMs.
Based on the perturbation theory, Bruno~\cite{PRB-39-865-1989} pointed out that the MCA can be formulated as
\begin{equation}
\label{eq1}
\text{MCA}=-\sum_i\frac{\xi_i}{4\mu_B}\Delta \mu_{i},
\end{equation}
where $\xi_i$ denotes the atomic SOC constant and $\Delta \mu_{i}$
is the orbital moment difference
between the magnetization directions parallel to [001] and [100] for the $i$-th atom.
We note that such a model is best applicable for strong magnets where the majority spin channel is almost fully occupied, whereas there is
a more general formula considering the spin-flip and quadruple terms~\cite{soc-van}.
Taking Ni$_2$FeGa as an example, Table~\ref{Table:s1} shows the atom-resolved orbital moments and the resulting contributions to the MCA using Bruno's formula,
where the atomic SOC constants for Ni and Fe are  630 cm$^{-1}$ (corresponding to 78.1100 meV) and  400 cm$^{-1}$ (corresponding to 49.5937 meV)
taken from Ref.~\cite{jcm-soc}.
The resulting MCA for Ni$_2$FeGa with C, N, and H interstitials based on the Eq.~(\ref{eq1}) are 0.316 meV/f.u., 0.528 meV/f.u. and  0.330 meV/f.u., respectively. Correspondingly,  the  MAEs based on  Eq.~(\ref{eqm}) are 0.296 meV/f.u., 0.439 meV/f.u. and 0.167 meV/f.u., respectively. The relative MAE differences of Bruno's  model to that of Eq.~(\ref{eqm}) are 17.17\%, 23.83\% and 79.61\%.
Nevertheless, the trend is correctly reproduced and we believe the atomic-resolved contributions evaluated based on Eq.~\ref{eq1} are still valuable to elucidate the origin of MCA.
It is noteworthy that the tetragonal distortion ratios for Ni$_2$FeGa with H, C and N interstitial are 1.39, 1.40 and 1.40, respectively (cf. Table~\ref{table1}).
To make a direct comparison to the pristine Ni$_2$FeGa, we evaluated the MCA and orbital moments for Ni$_2$FeGa without interstitials but with imposed c/a=1.40, resulting in an MCA of 0.066 meV  and  0.170 meV per chemical formula  by using Eq.~(\ref{eqm}) and Bruno's model Eq.~(\ref{eq1}), respectively.
Again, the MAEs  obtained from the Bruno's model can be well compared with that from Eq.~(\ref{eqm}) for  Ni$_2$FeGa with C and N interstitial, but not for H interstitial case and parent compound.

The remarkable variation of the orbital moments and the resulting significant enhancement of MCAs can be attributed to the atoms surrounding the interstitial atoms.
It is noted that C and N interstitials can give rise a significant MCA to Ni$_2$FeGa, while the effect of H interstitial is rather weaker.
Following Table~\ref{Table:s1}, it is clear that without interstitials (c/a=1.40), Fe atoms have the leading contribution to the MCA of 0.26 meV per atom,
while the contribution from Ni (about -0.039 meV per atom) is an order of magnitude lower with opposite sign.
The change in c/a from 1.35 to 1.40 has minor influence on the MCA and orbit moment.
After considering interstitial N (H), the contribution for Ni-i atoms within the same plane is enhanced to 0.250 meV (0.097 meV) per atom.
As to C interstitial atoms, the MCA of  Ni-i atoms is slightly (Fig.~\ref{fig:1}(b)) increased to 0.039 meV per atom.
That is, all types of the interstitial atoms lead to a sign change of the contribution to MCA for Ni-i.
On the other hand, the orbital moments and thus the resulting MCA contribution are very comparable for the Ni-ii atoms with and without interstitials,
because the Ni-ii atoms are far away from the interstitials.
Furthermore, for the H interstitial case, both the MCA and orbital moments of all Fe (including iii, iv and v) atoms change only slightly comparing to those in the pristine compound with imposed c/a=1.40,
whereas the N and C interstitials lead to significant enhancement of contribution for Fe-iii atoms to MCA.
For instance, the MCA contributions of Fe-iii atoms below the interstitials are increased to 0.681 meV and 0.508 meV per atom with N and C interstitials, more than two times larger that (0.260 meV) in the parent compound.
Meanwhile the contributions from Fe-iv and Fe-v atoms are slightly reduced.
Therefore, the interstitial atoms have very strong influence on the MCA of the local surrounding atoms, while the global tetragonal distortion has relatively marginal effects.

The effects of interstitials on MCAs and orbital magnetizations can be further understood based on the chemical
bonding pairs between the interstitials and surrounding magnetic atoms.
For instance, the octahedral center (interstitial) H, C and N to octahedral planar corner Ni-i almost have the same bond lengths as 1.85  \AA,  1.88  \AA \space and 1.88  \AA. However, the integrated COHP of H-Ni  bond is just -0.63 eV, which is much weaker than that of the comparable bond strength of C-(Ni-i) (-2.12 eV) and N-(Ni-i) (-1.96 eV) bonds.
On the other hand, the octahedral below  corner Fe-iii to the  interstitial H, C and N have similar bond lengths as 1.65 \AA,  1.83 \AA \space and 1.83 \AA, while the bond integrated COHP of H-Fe (iii) (-1.24 eV) can be comparable to that of C-(Fe-iii) (-2.88 eV) and N-(Fe-iii) (-2.38 eV) bonds.
Obviously, the bond strengths of C interstitial to Fe-iii) and Ni-i are the strongest. This explains the significant change of orbital  moments of Ni$_\text{2}$FeGa with C interstitial comparing to Ni$_\text{2}$FeGa at the same tetragonal distortion ratio without interstitial.
In this view, the H interstitial just induce tetragonal distortion to Ni$_2$FeGa,  while C and N interstitial not only induce tetragonal distortion but also change the chemical environment by forming strong bonds.
We notice that the interstitial to planer Ni-i atom  have comparable bond lengths as to lower Fe-iii atoms but weaker integrated COHP for each interstitial cases. Such bonding behaviors explains the effect of interstitial on the magnetization and the  MCA for Fe-iii atoms is stronger than that for Ni-i atoms.

\section{Conclusion}

Based on high-throughput DFT calculations, we investigated the effects of (H, B, C, and N) interstitials on the magnetic properties of cubic full Heusler compounds.
We identified 32 compounds with substantial uniaxial MAE.
Detailed analysis reveals that in addition to the breaking of the cubic symmetry, the changes in the local crystalline environment can induce significant contribution
to the MAE, which can be attributed to the chemical bonding between the interstitial and surrounding magnetic atoms. This could provide an efficient way to
design permanent magnets, which shall be explored further both experimentally and theoretically.

Channing Kennedy and a baby interview some folks
Who Channing is
PHOWM interviews
PHOWM on Instagram
Channing on Twitter
Hi! My name is Channing Kennedy and I live in Oakland, California with my family and two large cats. My primary occupation, at the time of this writing, is that I'm a stay-at-home dad and a longtime preschool storytime volunteer, both of which I enjoy a lot.
Previously, I've been a racial equity consultant for arts organizations, a journalist and essayist, a video and podcast producer, a writer and performer of live comedy, a director of a major arts festival, and (a long time ago) a guy who ran a record label and was in a few bands. Most of my work deals with racial justice's role in the arts and vice versa, with a focus on gender and disability within that relationship and on my own identity as a straight cis white dude as a byproduct of this greater dynamic.
I'm interested in birds, vegetarian cooking, and children's publishing. During the summer of 2014, a photo of me was the top Google Images result for the phrase 'white guy.' You can email me at channing@channingkennedy.com and I'm also on LinkedIn.

Atten-tion! The Best Military Watches for Civilians
By Michael Carl
The Ceramica was first created for the underwater exploits of the commandant of the first submarine corps. I don't dive (there are sharks, duh), but I think the watch is really cute. The matte black makes it look super-slick, and the band is long enough that—should you be foolish enough to dive—it will fit over your wet suit. Be careful, though: great whites are terrifying, but nurse sharks are the most dangerous.
Panerai PAM00292 Radiomir Black Seal Ceramica. $9,600, available at Officine Panerai boutique (545 Madison Avenue, New York; or 9490A Brighton Way, Beverly Hills).
This watch is a tribute to the place in California where the legend of the elite Top Gun pilots was born. IWC has opened its first flagship store in New York, which is pretty cool. It has a realistic flight simulator that is definitely worth checking out while you are picking up this watch for me. If you (or I) wear this watch on the street in the city, you can be sure all the sailors will stop and stare at you (me). And then I'll say, with a nod of my head, "That's right, Ice . . . man. I am dangerous."
IWC Pilot's Watch Chronograph Top Gun Miramar. $12,700, available at IWC's New York flagship boutique (535 Madison Avenue; 212-355-7271).
This was the first timepiece worn by pilots in the 1920s. The pilots used to strap them around their thighs because the wristwatch had not been invented yet. It sounds to me like it could have been a super-sassy—yet practical!—waist cincher, or as normal people call it, a belt, a belt that you wear on your thigh. Either way, it's a fantastic, vintage-looking watch with any kind of band.
Bell & Ross WW1-92 Military. $3,300, bellross.com, 888-307-7887.
The Swiss Army Infantry mechanical takes key style cues from classic aviator watches, but the overall look reflects the values of military engineering and the core heritage of Victorinox Swiss Army. This watch screams "practical and tough." According to Victorinox, it's an ideal "companion for life." That might be a stretch—I am still holding out for a unicorn as my life partner—but I will definitely add this watch to my collection, which I do plan to have for life.
Victorinox Swiss Army Infantry Vintage Mechanical. $650, swissarmy.com.
To mark the centenary of France's naval aviation (I know, but, yes, France does have a navy), Breguet issued this special Type XX design with only 1,000 numbered models. Not only is this watch exceptionally good looking, it has a solid case engraved with the official emblem of the French naval air arm. Vive la France!
Breguet Type XX Aéronavale 100th Anniversary Limited Edition 3803ST. $9,700, breguet.com.

Google to end Chrome support for Windows XP and Vista in April 2016
By John Callaham
If you are still using a Windows XP or Windows Vista PC, it's time to think about trading up. Microsoft ended support for Windows XP in 2014, and Vista's support will stop on April 11, 2017. Google plans to stop supporting and offering updates for its popular Chrome browser for both Vista and XP in less than a year.
Google stated:
"Today, we're announcing the end of Chrome's support for Windows XP, as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple. Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes. If you are still on one of these unsupported platforms, we encourage you to move to a newer operating system to ensure that you continue to receive the latest Chrome versions and features."

Anything that can make people upgrade. Good!
or make them change browser (easier and cheaper)
How isn't upgrading cheaper? Its free upgrade isn't it?
I think that's only W7 and up
Not if you are on XP and Vista. But this is good nonetheless.
The only browser left is Firefox, which I'm guessing will follow pretty soon
Mozilla Firefox doesn't support Windows XP at all. They require it to be installed on Vista, 7, 8, and 10
this is nothing new
Xp and vista should be buried by now.
Nobody uses vista, but xp.....
Very few use xp right now
Windows XP still has 15% market share (down from 40% before Windows 10 was released)
The only people using it are those in 3rd world countries that are using pirated versions of it.
WRONG, I know a lot of people who still use and LIKE vista...never mind companies... XP, I still see in use as much as 7...I work in IT..
I saw XP in use at a major hospital. I couldn't believe it.
Have a vu partition just to run tinker & a msdos vm(old school games that use protected mode) & some older games & w7 for everything else
I still have one Vista PC in use.
XP exists as a forked version in some cash registers. MS still supports those, I think.
#Scroogled again! /s
Hardly... this could finally get those XP users to upgrade to a newer OS (likely either Windows 7 or 10). So this is actually a win for Windows.
/s = sarcasm
Time to move to a Mac for sure!! Gates has made enough on me!!!
They were still supporting vista?
Amazing huh? Lifecycle of OSX is a lot shorter... 10.8 was released in 2012, while XP latest release was in 2008. Four years earlier and still supported by Google Chrome!
...because it was still supported by MS and still had a relevant market share.
Vista is supported until April of 2017, which is approximately 10 years from launch. XP got extra life, but MS supports Windows for at least 10 years. There's the first 5 years, which is called "mainstream support" (meaning bug fixes and potentially new features or product updates), and then the "extended support" phase which runs through end-of-life (security updates only).
This will force more people moving to w10
Nah, they'll just stick with whatever browser they have been using..
In my experience most older people tend to want to stick with XP because it is simple, and because it has Outlook Express. For sheer simplicity, it still hasn't been surpassed - and Google still allows Picasa images to be shared directly to Outlook Express.
XP is still an amazingly usable OS...and I can see why people are entrenched and not wishing to upgrade.
Picasa still exist?.. :-0
It's more powerful than any Microsoft photo management application...so yes, it still exists.
Never saw anyone using it since the days of XP ... My bad :-/
What about Google Plus?.. Still there?
Google Photos and Google+ is way better at photo management than Picasa (also owned by Google)
"Vista's support will stop April 11, 2017" "because they are no longer supported by Microsoft and Apple" Well, something doesn't seem right.
""No longer "ACTIVELY" supported""
... You have the answer now :)
Well at least Google chrome did better than Microsoft in terms of Supporting.
They are giving every user a free cookie
and free trojan malware with each visit to online banking and email account access
Microsoft did the right thing by ending extended support in 2014. The original date was 2011 but then Microsoft was forced to push it for 3 more years because many companies didn't upgrade to Windows 7 / 8. The interesting thing will be if Google Chrome support ending will force the small percentage of people on XP to move on. At least move to Win7
more stupid comments by you? you really have a sad and pathetic life.
Finally google release XP
Microsoft should release some software to make WinXP users upgrade to Win 10 non-genuine license for free
I'm surprised they didn't recommend upgrading to a Chromebook
People who are still on XP don't have the technical savvy to really understand the cloud, or are keeping it for some work critical program that definitely wouldn't work in Chrome OS.
Yes and there are some programs/applications made for Windows 98 and XP that WILL NOT work on Windows 7 and 8 let alone Windows 10
Why not? Because those developers won't update it? What is keeping these programs from working on the newer operating systems?
yes and because the software company no longer exists? There are a lot of computers at my school's lab that run Win XP and Win 98 simply because they won't work on newwer computers. Some of the equipment is connected to computer through Serial and Parallel ports, and some are connected through COM ports. Also the software companies that made the programs, no longer exist and there are very few alternatives, so schools and businesses choose to stay on older computers
Even in compatibility mode or a VM? Edit: Seems like if they were critical applications, someone would have rebuilt them.
yeah it's sad to see really old computers still around and I wish people would hire developers to rebuild the programs to run on newer OS
I don't necessarily think its sad, I just think it's the next logical step. For example, if you're using a device that uses XP embedded to measure soil acidity near active volcanoes, wouldn't it make since to recode the applet to run in W10 embedded for a smaller, more efficient device? Logically, that equipment is going to break eventually, and that applies to everything. Sure, maybe parking ticket gateways running an embedded OS don't need upgrades every 4 years, but waiting until the system crashes and needs ~4 days for replacement seems like a risk.
The last version of XP embedded was released in 2009 and is supported through 2019, so while that may be a noble goal I wouldn't expect a migration to Win10 universal apps on that platform until at least the end of the decade.
10 actually has better backward compatibility than 7/8...
Time to go to a Mac....
I like Internet explorer and internet downloader manager .... Who cares Google and it's services
A lot of people do...its just that most of us here in WC doesn't ;)
I use YouTube more than most every other site. Just bring honest. I don't like Google but YouTube is just the best by far. If there were an alternative that was as mature, then I might consider switching. My website is also made on Google Sites. I don't like Google very much and I only use Bing and Edge, but they do some things very well.
That's it, I'm switching to Edge.
Edge is only available on Windows 10
No. I'm running it on Windows 95. It's great. It only takes a minute and a half to load web pages.
This is weird, vista isnt going eol for another 2 years but google goes like "nah fk u" As a vista user im... well i use firefox so i dont give a shit, but yeah.
Thanks but I will be using Edge from now on. I've had enough of Google and that definitely includes Android. I don't even use Chrome on Android anymore. I'm done with almost everything Google except YouTube and Google+. Posted via the Windows Central App for Android

Book Review - The Way Home For Wolf
A touching story of an independent-minded wolf cub who finds his way home.
Wolf cub Wilf doesn't want help from anyone. Whatever it is, he can do it all by himself. But when he finds himself lost and alone in the chill of the Arctic night, Wilf discovers that sometimes we all need the helping hand of a friend.
A stunningly illustrated story from the creators of the bestselling, multi-award-winning The Lion Inside and The Koala Who Could.
This was such a nice story that shows the power of people helping others and learning about how someone can pass this gift of helping others on. The book is a beautiful story with amazing images and brings so many animals together that work together in a unique way to help a friend in need, even if you do not know the friend.
Book Review - Bunny Business (Mama's Day at Work)

It's morning when Mama gets the call that the bunnysitter is sick. But Papa is out of town and school is out. That means Bunny gets to go to work at Mama's office! But the big city isn't all it's cracked up to be, even with its many distractions. Boredom and hunger strike, and Bunny has to take up the mantle to save Mama's office from the workday blues.
Bunny Business is the perfect read aloud for working parents and their children. They will laugh and cheer at the ingenuity of one bunny's impromptu Take Your Child to Work Day!
For anyone that has a child that has come with them to work you know that things may not go as planned and you will see what happens when this momma bunny brings her son with her.

Book Review - Alpacas with Maracas
Macca and Al are two alpacas with a lot of enthusiasm but not a lot of talent. Can they find the right act in time for the talent show?
"You're a genius, Al! We don't need a big fracas!
We can't sing or play, brother, but we can shake like no other.
We just need... MARACAS!"
Macca and his best friend Al are always looking for ways to brighten their days. When they see an ad for a talent show, they're all in. But unfortunately, everything the cuddly duo tries, from singing and dancing to magic and gymnastics, is mediocre at best... until they discover the perfect act. How will the audience respond to these alpacas with maracas?
With quirky rhymes and adorable illustrations, this fun-filled sequel to Macca the Alpaca will have kids shimmying, grooving, wiggling, and moving along with Macca and Al. Chika chika cha cha cha! Ticka ticka ta ta ta!
This was a great book that lets you see two best friends having a ton of fun together and trying to figure out what they can do for the talent show. I love seeing that they try hard and put their whole hearts into everything that they do whether they are good or not. This was a ton of fun to read and with the rhyming cadence and illustrations you are brought into the book even further. The pictures are a ton of fun and you see topics of friendship, hard work and more !
Book Review - Macca the Alpaca
Macca the Alpaca is the alpaca-llama mashup of the year! Perfect for fans of Oi, Frog! and You Can't Take anElephant on the Bus. Macca is an alpaca. He loves splashing in puddles, and he gives the very best cuddles. Harmer is a llama. He's tall, strong and woolly, but he's also a BIG BULLY. When a friendly alpaca comes face-to-face with a meanie llama,he soon realises that LLAMA DRAMA lies ahead. But, who knows, perhaps the differences that separate the two will be exactly what brings them together in the end. A heartwarming story of friendship, acceptance and the value of being yourself.
This was a great book that shows you that you can accomplish anything that you put your mind to and that someone, even someone smaller can go up against a bully and come out ahead. This book is so much fun with a rhyming cadence and illustrations that are a ton of fun as well. The book touches on topics of friendship, acceptance and the idea of being true to yourself!
Book Review - Most Wanted: The Revolutionary Partnership of John Hancock & Samuel Adams
John Hancock and Samuel Adams were an unlikely pair of troublemakers. Hancock was young and dashing. Adams was old and stodgy. But working together, they rallied the people of Boston against the unfair policies of Great Britain and inspired American resistance. And to King George, they became a royal pain.
When the British army began marching toward Lexington and Concord, sending Hancock and Adams fleeing into the woods, the two men couldn't help but worry--this time, had they gone too far?
Rich with historical detail and primary sources, this spirited tale takes readers through ten years of taxes and tea-tossing, tyranny and town hall meetings. The team behind Thomas Paine and the Dangerous Word reunites for a lively look at the origins of the American Revolution told through the powerful partnership of two legendary founders.
This book was filled with so much detail and information and I can say that by the end of the book my eyes were open to all of the things that these two did together that many people may not be aware of at all. The book also shares the distinct differences which makes you realize that this partnership was a bit unconventional. That being said, even though that is the case, it was a powerful one. Get ready to learn and have fun with the story itself, as is holds a ton of learning surprises too.
Book Review - Diary of a Pug: Pug's Snow Day
It's a snow day, and Bella is thrilled. There's no school, so she and Bub can play outside all day. Trouble is, Bub does not like the snow it's slippery, freezing cold, and wet! What's even worse, there's a new kid next door, and he has a scary, monster-sized pet. Can Bub get past his fear of the snow and make a new friend at the same time?
With full-color artwork throughout, this funny and charming diary-format early chapter book is perfect for anyone who believes a furry pal is the best kind of friend.
This is a great addition to the series where we see Bella and Bub in another early reader that was fun and talked about topics that were important for any young child to know about dealing with fear, friendship and more.
Book Review - Love, Sophia on the Moon
Life on Earth isn't always fair, so Sophia runs off to the moon, where there are no bedtimes, no time-outs, and no Mom.
But as Sophia and her mom send letters to each other, Mom has a clever comeback for all of Sophia's angry notes. Home starts to sound not-quite-so-bad, especially when Mom reports that someone from the moon has moved in to Sophia's old room, they're having spaghetti for dinner, and they're reading Sophia's favorite story at bedtime.
A through line of unconditional love underscored with lots of humor and imagination makes this picturebook a stellar pick for storytime.
This is such a cute story, sharing letters between mom and daughter as she has run away to the moon to escape her mom. The letters are so real and fun and mom does a great job of working to get reconnected to her daughter in the end. If you want a story that you and your kids will love to share together look no further than this. The illustrations also draw you further and further into the book!

Training is known to improve performance in a range of sensory-motor tasks and alter white-matter connectivity, as measured by Diffusion Tensor imaging (DTI). Yet, learning to extract the statistics of event streams in natural environments is thought to often occur without explicit feedback (i.e. by mere exposure to the environment). Here, we demonstrate that this type of statistical learning of temporal structures without trial-by-trial feedback relates to changes in white-matter connectivity in the human brain. Our findings provide evidence for distinct cortico-striatal circuits that support individual ability to learn behaviorally-relevant statistics. In particular, individuals engage dissociable structural brain networks depending on their decision strategy, suggesting alternate brain routes to learning predictive structures.


Al Ittihad emerged victorious over Al Faisaly in the Saudi Kings Cup final on Saturday evening -- a game that also happened to feature one of the strangest advertising stunts ever witnessed at a football match.
Indeed, fans were left scratching their heads as a miniature jumbo jet plane (carrying a full flight crew) was rigged up to follow the movement of the ball as it moved around the pitch.
While utterly bemusing, the elaborate gimmick certainly gave new meaning to the phrase "flying down the wing."
Seeing as the game went to extra time, we have to presume that the plane managed to keep trundling back and forth for the entire 120-minute duration. Travel sickness pill anyone?

A Life of Meaning
'We are gathered here together to get through this thing called life.' This line from the musical icon Prince says it all. We have chosen this time to learn our life lessons and celebrate along the way. Prince showed us the power in diversity, acceptance and love. His message of unity is perfectly juxtaposed in a world of discord and division. He stood for social justice and lending a hand to those in need. The timing of his death seems to serve as a signal to all of us…to think, do and love.
Prince challenged us to feel something bigger, deeper within ourselves. You could feel the Universal light force in him. He did not allow himself to be bound by time, race, gender or profit. He was beyond, above all of that, and pushed us to celebrate the importance and magic of life.
What causes a performer to be able to reach audiences spanning from their 20's to their 80's – beyond genres and generations? Simply, the universal values of truth, caring, acceptance and love – the ultimate wins in life. His songs, a true inspiration in themselves, were paired with a quiet philanthropy that only a few of his closest friends were even aware of – 'just quietly do from your heart' could have been his tag line.
His spiritualism was evident from his famous 3 lens sun glasses (the middle lens designed to emphasize his third eye – the eye of enlightenment and higher consciousness) to the famous lyric, 'I never wanted to cause you no trouble, no pain, only wanted to see you laughing in the Purple Rain.' When we think of the words in that hit song we can imagine the rain as a cleansing element. When paired with the color purple which represents imagination, strength and integrity it signifies the union of body and soul in spiritual fulfillment. Faith in something bigger than himself gave him the personal power to carry on and on and on to produce 39 albums in 35 years – an unheard of accomplishment.
Prince literally had his name taken from him (at birth he was named Prince Rogers Nelson by his mother) early in his life as both his music and name were hijacked by the music industry – all in the name of profit. He was also challenged by personal choices of escape. Yet through it all he continued to work to show us that no matter how grim things appear, we must never give up seeking truth to become a better person.
The mark he made on our world was evident. Last night the entire New Orleans Super Dome was awash in purple light, the streets closing in Brooklyn so people could dance to his music and the emotional tributes offered by so many including the President. Kind just takes your breath away.
It's not just his music but his message of inclusion, acceptance and celebration of the life force within us that will help us survive, thrive and evolve as we face tomorrow.
I visualize Jimmie Hendrix, Michael Jackson and David Bowie, among others, extending their hands to him as he passed on and with a nod and smile simply saying, 'Welcome home brother, thank you for a life well-lived.'
Have a meaningful few days.

System Human Resource Services » Employee Development & Engagement » Distinguished Employee Leadership and Team Award (DELTA) » DELTA Project Team Award
DELTA Project Team Award
2022 DELTA nominations will be accepted starting Tuesday, January 18 and are due Monday, February 21, 2022.
A project team consists of a minimum of four individuals working on a project sponsored by one or more units within the System. For the purposes of the DELTA program, the size of teams would typically range from four to fifteen qualified members.
The individual team members must meet the qualifications for individual eligibility or they will be individually disqualified from the team.
Project teams may consist of a combination of civil service and academic professional employees.
Project teams may be comprised of individuals from one unit, or it may be a cross-functional team.
Seventy-five percent (75%) of the project team members must be employed by a System Office unit. If a project team has a university employee(s) from UIUC, UIC (including UI Health) or UIS, the university team members are not eligible for the award.
Project teams must have completed their work on the specific project for which they are nominated during the award cycle (August 2020 - December 2021*). Project completion is defined as one or more of the following:
The system or process for one campus or unit is in production for a multi-year project. This means development, testing and piloting are finished and the project has been implemented.
The project team has entered the "clean up", decommissioning, or continuous improvement phase in one or more unit(s), campus or location.
The results of the project must be identified in the nomination process.
The project for which the team is being nominated should have a finite beginning and ending.
A team that is working on a project, which spans multiple years, is only eligible to receive the DELTA award once that project is completed. For a multi-year project, it may occur after the completion of the entire project or a portion of the project is completed. See the definition of project completion listed above.
If an entire unit is nominated as a team, the unit must be nominated for work on a specific project, which is above and beyond the normal duties of the unit.
Employees who have previously received either the project team or individual award and are currently on a team selected for the project team award are not eligible for the monetary award until five years from the date of receiving their previous individual or team award. However, he/she may be recognized as part of the awarded team and will receive a certificate and invitation to the award ceremony.
*NOTE: For the 2022 awards, the award cycle is extended from August 2020 through December 2021. Future award cycles will be January 1 through December 31.
Awards will be given based on the degree to which the project team meets the following criteria:
Demonstrates and models attributes of successful high performing project teams.
Provides value added results.
Communicates and manages expectations around project timing and expected results.
Engages stakeholders in their sponsorship role to provide the resources (talent, tools, and facilities) to complete the project team engagement.
Delivers results that at minimum meet and potentially exceed expectations.
These five areas are qualities that are valued by the System. Please see the Project Team Criteria for assistance in determining where specific examples or qualities should fall.
Nominations may be made by any member of the university system community (civil service, academic professional, faculty or student). The nomination of teams for this award is a three-step process:
Step One - Nomination
First, the nominator must submit the online nomination by the deadline.
The online nomination form requires the following:
Nomination Statement (View Sample) - The nomination statement includes the following:
A brief description (approximately one paragraph) of the project team's objectives.
Descriptions of how the project team meets the award criteria. Nominators must provide specific supporting examples for each of the criteria, in addition to a general description of the project team's collective characteristics on these criteria. Please see the Project Team Criteria for assistance.
Nomination statements should be no more than two pages, single-spaced with at least a 10-point font.
In the event multiple nominations are submitted for a project team, the selection committee will select the one nomination for that team that most closely exemplifies the objectives of the Distinguished Employee Leadership and Team Award.
Step Two - Selection
The selection process is based on an independent review of the nominations and the award criteria. The decision to make a team an award recipient is based on the award criteria ratings and group discussion of the selection committee. In the event the selection committee cannot determine award recipients, finalists will be chosen and nominators notified if their team nomination is a finalist. At that time, nominators will be asked to provide two letters of recommendation. Nomination letters for project teams should represent the units that make up the project team. The nominator is responsible for selecting the appropriate individuals to provide letters of recommendation.
Step Three - Notification
The program coordinator contacts the nominator to inform them their nominee has been selected as an award recipient. Nominators are given the option of informing the nominee themselves or having the program coordinator inform the award recipient. A letter of congratulations will be sent via email to the project team award recipients (copying the nominators and their respective managers and/or department heads) officially informing them of the award. All project team award recipients will be notified of their nominator.
The nominators whose nominees did not receive the award will be notified with a letter via email.
Selection/Evaluation Process
Project teams will be judged in comparison to their peers in the award category. Examples and achievements will only be considered if they are related to work in the department and/or at the University.
At a minimum, one project team will receive the DELTA award each year. Individuals on the award winning project team will equally share in $5,000 (after taxes) allocated to the team, not to exceed $1,500 (after taxes) per person, and a commemorative trophy. Recipients will be honored at an annual award ceremony.

What happened during the Old Stone Age?

The Old Stone Age (or Paleolithic) is a very long period that dates from the first evidence that humans used stone tools they made themselves (about 3.3 million years ago) to approximately 11,700 BC.

The Old Stone Age (or Paleolithic) is a very long period that dates from the first evidence that humans used stone tools they made themselves (about 3.3 million years ago) to approximately 11,700 BC. During this period earlier humans, called hominins, evolved into the erect homo sapiens that humans are today. The period is marked by human control of fire, advances in tool technology, the development of art, human burial of the dead, and early religious ritual. However, despite evolution and technological advances, human life changed very slowly during this time.
No metals were yet used in constructing tools or implements, but tool construction continued to be refined. For example, the first hand ax was developed about 700,000 BC. In other places, strips or flakes of flint were fashioned into tools.
Art and religion developed in this period. Around 50,000 BC, an increase in art objects begin to appear, from carved wooden figures to cave paintings. During the Paleolithic era, humans also began to bury their dead.
During this long period, humans were hunter gatherers and largely nomadic. Agriculture, which is the cultivating of crops and the domesticating of animals, had not yet occurred. Because it was difficult to accumulate food surpluses, human populations tended to remain small, mobile (following the food), and were likely undifferentiated into social classes. Humans lived by hunting, fishing, and gathering wild nuts and berries.
Humans survived several ice ages or cooler periods on the earth during this time, with the end of the last one coinciding with the end of the Old Stone Age. After this period, much changed, and humans entered a period of explosive advancement and growth.

There's a reason to get fussy over gin
"I'll have a gin and tonic," said the man in late afternoon golfing attire.
"What kind of gin do you prefer?" I asked, as I always do with people who are not specific about their brand. I have learned that if you don't, they invariably have a preference, but only after their drink is made, causing the first 10 seconds of interaction to result in a loss for the bar when that drink gets thrown out.
"It doesn't matter," he said. "Does it?"
"I'd say it does."
"But I've read that vodka is pretty much all the same, and that gin is just juniper-flavored vodka."
Now I've actually written that vodka is pretty much all the same, and some gin is, in fact, little more than juniper flavored vodka. But not all gin.
Do just a little research into to classic cocktails and gin comes quickly to the forefront. Classic martini: gin. Vesper: gin. Aviation: gin. Last Word: gin. It goes on and on. But do a little more research and you will find that each cocktail calls for a different kind of gin. Now when you deal with vodka you are talking about tiny subtleties, fractions of a percentage that minutely alter flavor or feel. But with gin it's an entirely different ball game.
There are two main types of gin — Dutch and English gin. Dutch gin, sometimes called jenever or Holland, is big and robust and practically unheard of in the United States. In fact the best-selling gin in the world, Ginebra de San Miguel, a 100-plus-year-old gin that outsells Bombay, Beefeater and Tanqueray combined, is a Dutch-style gin made in the Philippines. And it is not available in the U.S.
The gin most Americans are familiar with is English gin. But within that category fall the three main types of gin — compound, distilled and London. U.S. law stipulates that gin's main characteristic flavor must be from from juniper berries and be bottled at not less than 80 proof, and that gin "produced exclusively by original distillation or by redistillation may be further designated as 'distilled.'"
For further clarification the European Union definitions are used for the three main categories of gin:
• Gin (or compound gin): If it just says gin on the bottle, what you are drinking is basically a neutral spirit that has had flavorings added to it after distillation, sort of like an alcoholic tea. These products don't have to be distilled to high proof, so you might get flavors from the original distillate (sugar, wheat, corn, etc.) as well as from the water added to it (the purest ethanol possible is 192 proof or 96 percent ethanol and 4 percent water), plus the juniper and literally any other flavor the company wants to add in almost any combination. All of which means that these products taste radically different. Sometimes they are not even shelf stable in regards to color, and sometimes they actually "louche," or when gin turns slightly opaque when combined with water or ice.
• Distilled gin: Don't be fooled. The product must say "distilled gin," not just have "gin" and "distilled" on the label somewhere, so read carefully. These products have the juniper berries and other additives distilled with the original distillate. They are usually regarded as a superior product because the distillate is controlled, start to finish, and they are both flavor and color stable.
• London gin: Not to be confused with English gin, London gin is produced like distilled gin, but uses only the highest grade ethanol. It must be made using only all-natural plant material to flavor it (no essences or additives), and it may not have anything added after distillation except for a trace amount of sugar and water to bring it down to proof. London gin is sometimes supplemented by the word "dry," but dry is a subjective and somewhat arbitrary term. Not all "dry" gin is London dry. London gins can be made anywhere in the world, but Beefeater is the only London dry gin in the world actually made in London.
All of which means that unlike vodka, which is an argument over the subtleties of the taste of water, whatever gin you mix your favorite tipple with makes all the difference in the world. Gin can be as different as apples and oranges, because legally, it can have both. Or neither.

From its clean, quiet drive through an all-electric powertrain, to its remarkably peppy acceleration and full assortment of tech features, the new 2019 Nissan LEAF remains one of the more well-rounded green cars on the market. Eco-friendly drivers may expect to sacrifice some comforts and usual offerings when choosing an all-electric car like the LEAF, but Nissan's been ahead of the game, giving folks from the Charlotte, Matthews and Mooresville areas plenty of amenities that make this electric vehicle a smart choice. Visit our Concord, NC Nissan dealership today and find out if the new 2019 LEAF is your best bet.
Instead of fuel economy, electric cars are measured by their driving range, and the LEAF has long boasted strong capabilities in that regard, giving you up to 150 miles driving around Salisbury, Huntersville and Kannapolis before needing a charge. Later this year, a new LEAF Plus model will offer more than 200 miles of clean, easy driving. For charging, a household-style outlet will do the trick over a weekend for a full charge, while a special 220-volt station you can install or find around Charlotte will get you back full in no more than 7.5 hours.
The technology that goes into the electric drivetrain of the new LEAF is incredibly impressive, but the tech you're mostly interested in is found on your dashboard. Standard features include Bluetooth and a USB port, as well as a forward collision warning system with automatic braking. Moving up to higher trims adds smartphone integration, LED headlights, leather seating and even more features you'll like having with you for your travels around Concord and Charlotte.
Your Next Clean and Green EV Car is Only a Short Drive Away!
Hurry on over to Modern Nissan of Concord today and we'll be more than happy to go over your options and we'll introduce you to the clean and green world of EV driving.

Q: Load Balancer and using multiple SSL certificates Here is our current production configuration at a 3rd party data center:
•2 LINUX/CentOS tomcat web servers behind a shared load balancer
 •DNS entries point to the load balancer
 •Web apps are written using Java 6, Spring 3, Hibernate 4.
The data center techs have told us that in order to use the load balancer to forward port 80 to 8080, and forward 443 to 8443 (so we don't have port numbers in our URLs) we must have SSL certificates installed on BOTH the load balancer AND on the tomcat web server.  But this affects our performance/throughput, and limits the number of SSL connections (i.e. users) we have connecting to our web apps concurrently.
Does having both SSL certs make sense, or can this be simplified and just install the SSL certificate on either the load balancer, or the tomcat web server, but not both. And which one would be preferred?
Thanks in advance - Mark

A: I suspect this limitation is due to a limitation of their product, or in their management of that product. I don't see any technical reason that would require it in principle.
However, I would suggest that it may well be better to have a web-server (eg. Apache, nginx) fronting your Java container on each of the member-servers. That gives you the ability to let the web-server do more of the work with regard to serving static content and caching, etc.
I would expect that for a deployment where SSL can be terminated at the load-balancer (ie. not a high-security site where you really want SSL to the server), the load-balancer would need to have a way of injecting (and sanitizing) HTTP headers to inform the member-server if the request came in over https, etc. But you do need to be careful that people can't get to the member-servers directly (they could inject their own headers).
For most enterprise-scale deployments, terminating the SSL on each of the member-servers is the normal thing. I don't have experience in scaling that out though.
