A Travel Authorization letter is written by a person who is giving authority to another individual to carry his belongings, valuables, etc. The travel authorization letter has to be addressed to the higher authorities in tourism department of the particular airline. This letter contains passport details, information about your flight and phone number or email id of the person. Since it contains sensitive information, special care must be taken with it.
This makes it easier for you to travel to other parts of the country since many states and continents out there, require this type of letter especially if you are below the age of eighteen. For example, if a school has organized a trip, you would be necessary as a parent to fill a travel authorization letter as proof that your kid has the parent's approval to go. It is used commonly by many types of authorities and knowing how to draft it is an essential skill.
It is essential, especially if you are a parent to give full information about yourself and also current address and contact information in the case that you will be needed for inquiries or if something comes up.
If it's your child who is going on that trip, make sure to give the information about them.
Make sure not to write a long boring letter but just a simple short letter with all the necessary information. Giving the accurate information and relevant details.
In case if you want your child to be accompanied by another adult, you are well advised to write about that individual, giving the right information. Also, don't forget to keep it formal.
Use our free Letter to help you get started. If you need additional help or more examples check out some of the sample letters below.

Q: Unpack multiple dictionaries as functional arguments without repeating double asterisk I use API with long name of argument parameters. Consequently, I create following dictionaries for most common combinations of values which are then unpacked in function calls.
a_T = {'API parameter a': True}
a_F = {'API parameter a': False}
b_100 = {'API parameter b': 100}
b_0 = {'API parameter b': 0}
hello = {'API parameter c': 'hello'}
bye = {'API parameter d': 'goodbye'}

myf(**a_T, **bye)
myf(**b_0)
myf(**a_F, **b_100, **hello, **bye)

Is there any way to avoid repeat double asterisk? The code becomes quite unreadable with many of these strange characters.
Once could then add this unpacking utility to myf:
myf(a_T, bye)
myf(b_0)
myf(a_F, b_100, hello, bye)

A: You can actually use | for Python 3.9+ to combine all the dictionaries then send unpacked version.
def fun(**kwargs):
    print(kwargs)

>>> fun(**a_F| b_100| hello| bye)
{'API parameter a': False, 'API parameter b': 100, 'API parameter c': 'hello', 'API parameter d': 'goodbye'}

Or just use *args and pass multiple dictionaries:
def fun(*args):
    print(args)

>>> fun(a_F,b_100,hello,bye)
({'API parameter a': False}, {'API parameter b': 100}, {'API parameter c': 'hello'}, {'API parameter d': 'goodbye'})

Another solution is to use Python decorator and take care of ugly part inside the decorator function:
def decorator(fun):
    def wrapper(*args):
        from functools import reduce
        kwargs = reduce(lambda a, b: a | b, args)
        return fun(**kwargs)
    return wrapper
@decorator
def main_fun(**kwargs):
    print(kwargs)

>>> main_fun(a_F,b_100,hello,z)
{'API parameter a': False, 'API parameter b': 100, 'API parameter c': 'hello', 'parameter 4': 'goodbye'}

A: To unpack a series of dicts, use dict.update, or a nested comprehension:
def myf(*dicts):
    merged = {k: v for d in dicts for k, v in d.items()}
    # do stuff to merged

OR
def myf(*dicts):
    merged = {}
    for d in dicts:
        merged.update(d)

Download Shazam for free on your Android or iOS device (Free) There is a significant probability that you are not the only viewer wondering what song is being played in that video if Shazam was unable to identify it as such.
Since most people like discovering new music, this is likely the case. If you read through the YouTube comments or search through them using the search bar, you can come across the question and the solution. You might begin by attempting it the traditional manner. To get started, scroll down the page a little bit so that more of the comments will load at once.
Then, to open the Find box in your browser, press the Ctrl and F keys simultaneously (or the Command and F keys on a Mac). Enter music, and then read through the comments to see what people have to say about it. The quantity and quality of comments on a YouTube video will determine whether or not this helps you discover the music in that video; therefore, it may not always work.
If you are unable to locate anything using the term song, you may also search using the terms music or track. Think of any terms that someone may use if they were asking you to describe a music to them. Using the specialized site known as YTComment Finder is an improved method for searching through comments for the title of the song.
This website, despite its lack of complexity, gives you the ability to search the comments of any video on YouTube. After clicking on the Search button, you will just need to input the video's URL to begin searching for it. When you get to that page, type music (or another term that's similar), and you'll see all of the comments that match.
If none of the comments indicate the name of the music, but someone else has asked for the title, click the "Replies" link that is located on someone's remark to see if there is a response that contains the answer.
If you don't discover anything, you may always try making a remark of your own and asking for assistance in identifying the song.
Include a timestamp with the music so that folks will know which one you are referring to. This will get the greatest results. Because timestamps in YouTube comments function as links, submitting a question like "What music is playing at 3:51?" enables users to quickly get to that point in the video by clicking on the link.

Prosopometamorphopsia is a visual disorder characterized by altered perceptions of faces. Facial features are distorted in a variety of ways including drooping, swelling, discoloration, and shifts of position. Prosopometamorphopsia is distinct from prosopagnosia which is characterised by the inability to recognise faces. About 75 cases of prosopometamorphopsia have been reported in the scientific literature. In about half of the reported cases, features on both sides of the face appear distorted. In the other half of cases, distortions are restricted to one side of the face (left or right) and this condition is called hemi-prosopometamorphopsia.

Presentation
Generally, faces tend to appear distorted to a person who is affected by this condition. Those who suffer from this condition are able to recognise faces normally but perceive them as strangely disfigured. These facial hallucinations are usually described as ugly, and have prominent eyes and teeth. Some have described the faces as having a cartoon-like quality. Faces have been known to be perceived as contorted and as having displaced features. For example, one patient described a person's face as having a nose deviated to the side, the mouth laying at a diagonal and one eyebrow being higher than the other. Prosopometamorphopsia may either involve perceptions of the whole face or only one side of the face (usually after right hemisphere damage).

Causes
The definitive cause for prosopometamorphopsia is still relatively unknown. However, several potential theories have been expressed in the literature in this area. Generally, this condition has been associated with damage or abnormalities in various brain areas (temporal, occipital, parietal, and frontal lobes). The development of prosopometamorphopsia has been recorded to be a manifestation of epilepsy in some cases. Hyperactivity in the core or distributed face areas (without lesions) may be connected to causation.

Functional imaging studies in humans have identified an area in the fusiform gyrus which is selectively activated by stimulation when exposed to faces called the fusiform face area (FFA). Another area known to be activated by face stimuli is the superior temporal sulcus (STS). This region is particularly active when having to process facial expressions, especially the expressive features related to the eyes. Therefore, it has been suggested that the prominent eyes (which is a typical feature in the facial perceptions) in the distortions recorded is more in accordance with increased activity (which would cause an over-representation of the eyes) within the STS rather than the fusiform face area.

Other studies, however, have found that stimulation of the posterior and mid-fusiform face selective regions in a patient with medication-resistant epilepsy resulted in perceptions consistent with that of facial metamorphoses (patient noted that the experimenter's face started to droop). This study found that the perceived distortions correlated with signal changes in the patient's FFA and not in the STS.

Diagnosis

Classification
Prosopometamorphopsia is considered a face hallucination and is included under the umbrella of complex visual hallucinations. Unlike other forms of hallucinations such as peduncular hallucinosis or Charles Bonnet syndrome, prosopometamorphopsia does not predominate at a particular time of day; it is a constant experience. However, patients with Charles Bonnet syndrome have noted descriptions of prosopometamorphopsia. This form of perceptual distortion along with others such as macropsia and micropsia (alteration of perceived object size) and palinopia (spatial and temporal varieties and polyopia) are classified under the category termed metamorphopsia. These facial distortions can occur to either hallucinated perceptions or true (non-hallucinated) perceptions. It is attributed to structural brain changes or functional disorders like epilepsy, migraine or eye diseases.

Treatment
Antidepressants such as citalopram and the antipsychotic quetiapine have been recorded as unable to facilitate improvements for these symptoms. Valproic acid was initially used to treat the woman who hallucinated the dragon-like faces and this alleviated her symptoms entirely, however, she went on to develop auditory hallucinations as a side effect. She was subsequently prescribed rivastigmine instead which reduced the auditory hallucinations and reduced her visual symptoms.

The 75-year-old woman in the previous study was treated with intravenous heparin infusion and coumadization over a period of 10 days which enabled the alleviation of her visual symptoms almost entirely. The type of treatment may vary depending on the cause of the facial distortions.

Case studies
One study reported a 24-year-old woman who developed prosopometamorphopsia after a childbirth. Initially she developed severe migraines and blurred vision mainly in her right visual hemifield and was in a confused state. The visual disturbances persisted long after the migraine had subsided several hours later. She described the left half of people's faces as "out of place" and would see these distortions irrespective of whether the faces were familiar or unknown. However, she was able to visualise the faces of familiar people in her mind without the distortions. She also did not report perceiving distortions in stimuli other than faces and demonstrated the same patterns a year after the first assessments. It was discovered that this woman had a left hemisphere lesion which resulted in distortions of the left half of the faces to which she was exposed. The unilateral aspect of the defect suggests that the early stages of face processing occurs in parallel mechanisms across both hemispheres and the right hemisphere then integrates the information that results in a unitary face representation.

Another study examined a 75-year-old woman who suffered from a sudden onset of nausea, dizziness and blurred vision. The central part of faces, especially the nose and mouth, were described as being out of shape. She claimed that noses looked narrow and lengthened toward the mouth which looked small and rounded regardless of whether the faces were familiar to her or not. She was found not to have any other impairments in her visuoperceptual performances, nor did she have any cognitive or psychiatric impairments. A T2-weighted brain MRI revealed an infarction in the right medial temporooccipital lobe including the parahippocampal gyrus (complement of the FFA).

A 52-year-old woman suffered from a lifelong history of seeing faces morph into dragon-like faces and reported hallucinating similar faces several times a day. Initially she would recognise the actual faces but after a while they would become black, grew long pointy ears and a protruding snout, displayed reptile-like skin and had large protruding eyes in bright colours. She would see these faces coming towards her several times in a day from objects like electric sockets. She has also had these hallucinations in the dark. She had previously suffered from recurrent headaches, passage hallucinations (to see movements in the corner of the eyes) and zoopsia (she saw large ants crawling over her hands). An MRI of the brain showed minor white-matter abnormalities near the lentiform nucleus and in the semioval center. The visual perceptions she had experienced were attributed to unusual electrophysiological activity in the regions of the brain that are specialised for face and colour in the ventral occipito-temporal cortex.

A 44-year-old woman reported to have begun seeing facial distortions. She perceived that people's faces would change to look more like caricatures of them and her perception worsened over time. She had a history of epilepsy in childhood and had suffered a concussion several years before having this condition, though no medical evidence of seizure was found during distortions. She reported that occasionally she would experience a pixelated vision, like television static and mentioned that these symptoms occurred several times a week with each event lasting from a few minutes to a few hours.

The climate is changing, even in Ticino. The year Protected content a new national temperature record, saw an extreme summer drought and abundant autumn rainfall. What we see today as an exceptional year, tomorrow could be a "normal" year. The CH Protected content scenarios, which were developed as a priority theme within the NCCS (National Center for Climate Services), describe Switzerland's future climate through numbers and graphs. In Protected content , the facts showed that everyone could see for themselves what the climate of the future might be like.
The CH Protected content scenarios, available at Protected content , form the basis for taking the necessary measures to manage the now inevitable changes and show how successful climate protection action can contribute to mitigating, at least partially, the expected impacts in the Alpine region. The measures to be implemented by the cantons and municipalities on the basis of what has already been achieved in recent years are therefore based on them.


Epoxidation is the addition of a single oxygen atom across a C=C double bond.
Earlier, we saw that alkenes can donate their pi electrons to electrophiles such as "Br+". In the bromonium ion that results, a lone pair on the bromine can donate back to the incipient carbocation, leading to a more stable intermediate.
We have also seen that addition to alkenes can sometimes be concerted, happening all at once, rather than one step at a time. For example, in hydroboration, the boron and the hydrogen add to the double bond at the same time.
The boron is adding just slightly ahead of the hydrogen. The initial interaction is donation from the pi bond to the Lewis acidic boron. However, as soon as positive charge starts to build up on carbon, and negative charge starts to build up on boron, the hydride is immediately donated. Time is not allowed for the charged intermediate to fully form before proceeding.
Really, that's what is happening to the bromine, too. As the alkene starts to donate its pi electrons to the bromine and begins to build up positive charge, the bromine's lone pair is drawn back to the alkene. As a result, the intermediate that we imagine with a full positive charge on carbon and no charge on bromine exists too fleetingly to be considered an intermediate at all. As soon as it begins to form, it is already turning into something else.
That sort of concerted addition happens with some other electrophiles, too. If an atom is electrophilic, but also has a lone pair to donate, that cyclic transition state can lead to the product in one step.
Alkene epoxidation is another example of this kind of reaction. An epoxidation is the transfer of an oxygen atom from a peroxy compound to an alkene. Peroxides contain O-O bonds, which are relatively weak and reactive.
To simplify a little bit, just look at the reaction from the point of view of the alkene. It's just picking up an oxygen atom, because the peroxide had an extra one.
When the oxygen atom is transferred, it forms an epoxide (sometimes called an oxirane). It is a three-membered ring containing two carbons and an oxygen.
Epoxidation results in transfer of an oxygen atom from a peroxide to an alkene.
Peroxides are compounds containing weak O-O bonds.
Like in a bromination, the electrophile is deceptive. It is an oxygen atom, which we more naturally think of as a nucleophile. However, just as Br2 contains an atom attached to a good leaving group (Br -), so do the kinds of oxygen compounds used in epoxidation. Most often, these are "peroxy acids", carboxylic acids containing an extra oxygen.
As in the bromination, as soon as the alkene begins donating to the electrophile, a lone pair can donate back, so that an unstable cation does not have to form.
The entire mechanism is believed to be concerted, based on a number of lines of experimental evidence. A number of things need to be accomplished; in addition to the oxygen donation, the leaving group must leave, and a proton must be transferred.
The reaction mechanism can be cleaned up slightly because it is thought to be an example of a pericyclic reaction. Pericylcic reactions frequently involving three pairs of electrons moving in a circle. Like the three pairs of electrons in a benzene ring, this structure is thought to be unusually stable.
Apart from peroxy acids, many other peroxides can be involved in epoxidations, as well as some metal oxides. In some cases, the reaction is extremely slow, but works better in the presence of a catalyst.
Epoxidation reactions display an almost counter-intuitive selectivity. Unlike hydrogenation reactions, which are generally easier with less-substituted alkenes, epoxidations are much faster with more-substituted alkenes. In the case of hydrogenations, the selectivity can be understood as a combination of steric factors (the alkene must bind to a catalyst) as well as thermodynamicic factors (more substituted alkenes are more stable, so they are less likely to react). However, in epoxidations, the more electron-rich the alkene, the more easily it can be induced to react with the peroxide. More substituted alkenes are generally more electron-rich than those that are substituted only with electron-poor hydrogens.
The Sharpless epoxidation is one of the most common methods of catalytically adding an oxygen across a double bond. The method generally employs a titanium catalyst; similar approaches use vanadium catalysts or other metallic species. As mentioned before, metal ions can sometimes accelerate epoxidations.
The Sharpless epoxidation is important partly because it selectively epoxidizes allylic alcohols: compounds containing a C=C-C-OH unit. That means that, in addition to being able to selectively epoxidize more-substituted double bonds in the presence of less-substituted double bonds, we can also select double bonds that are close to alcohols.
Circle the allylic alcohol in each of the following compounds.
How does the metal catalysis selectively identify that position? Remember, one of the important strategies in enzyme catalysis is approximation: the act of bringing two things together. An alcohol is a potential lone pair donor, so it could become a ligand for a metal ion. Ti4+ and V4+ happen to be very oxophilic -- they bind well to oxygen -- and so they are particularly suited for this task.
In this scheme, we're not worrying about exactly how the titanium ion gets to peroxide to give up its extra oxygen to the alkene; that's complicated. However, the fact that both the allylic alcohol and the peroxide can bind to the titanium gets them closer together, and makes them more likely to react with each other.
That's only part of the story of the Sharpless epoxidation. The other reason this method is important is its stereoselectivity. To get stereoselectivity, a chiral ligand is added for the titanium. It's usually diethyl tartrate (DET) or diisopropyl tartrate (DIT). Tartrate is chiral; there is a D-(-)-enantiomer and a L-(+)-enantiomer. The D and L are common symbols used to designate enantiomers in sugars; they relate the structure back to the biochemical grandparents of all sugars, D-glyceraldehyde and L-glyceraldehyde. The (-) and (+) symbols refer to the characteristics of this particular compound in polarimetry; the (+) enantiomer rotates plane polarized light in a clockwise direction, whereas the (-) enantiomer rotates plane polarized light in a counter-clockwise direction.
Assign stereochemical configurations (R and S) to the tartrates to confirm that they are enantiomers of each other.
If the D-(-)-isomer is added, one possible enantiomer of the product is obtained. If the L-(+)-isomer is added, the other possible enantiomer is obtained.
In general, we would get one enantiomer if the oxygen were added to one face of the alkene and the other enantiomer if the oxygen were added to the other face. In the drawing below, the face of the alkene towards us is sometimes called the "re face" (pronounced, ray face). The face of the alkene away from us is called the "si face" (see face). These words sound related to R and S configuration, and they sort of are like that, but they are used to describe two different faces of a flat molecule. Adding oxygen to the re face gives on enantiomer; addign oxygen to the si face gives another.
How does this preferred reactivity work? How does the metal manage to add the oxygen to one face but not to the other? Tartrates are oxygen-rich and so they bind very well to titanium. Remember, if we have a reaction site and we make it chiral, one enantiomer of the product is generally preferred. Enzymes are very compicated, chiral molecules, and they are good at producing one enantiomer of a product. By comparison, the titanium DET complex is a relatively simple chiral molecule, but it uses the same idea.
Now, it is really very difficult to look at these conditions and predict exactly which enantiomer would be formed in a reaction. However, we can look at a factor that might illustrate an underlying reason for the preference. In quadrant analysis, we look at the general shape formed by that bidentate tartrate ligand on the metal. In the pictures below, the red ball is the metal atom. The tartrate ligand extends up and to the right as it sits on the metal, and also down and to the left; it is cartooned in blue. As a result, if we think of the metal as sitting in the middle of a square, alternating corners of that square are filled, and the other corners are empty.
Imagine the alkene approaching that metal. The alkene will probably have a preferred orientation in which it will bind. Just for example, maybe it needs to bind with the double bond in the same plane as the ring formed by the titanium and the oxygens (horizontally in the picture). If it does that, it can reduce steric interactions with the ligand by binding one face of the alkene preferentially to the metal, keeping the biggest substituent on the alkane (the black ball) in a relatively open space. The alkene could also bind if rotated upside down compared to the first picture, but the same face would still be towards the titanium.
On the other hand, if the alkene tries to bind through the other face of the pi bond, the largest substituent would be in a more crowded space. That might be less favourable.
Overall, if the alkene has a preferred face that it will bind to the metal, then anything delivered from that metal will land on that face, and not the opposite one.
There are lots of variations on this model. Maybe it isn't steric interactions that influence how the alkene approaches the metal. Maybe it is some other factor, like hydrogen bonding, that pulls in the alkene oriented in one direction and not another. Nevertheless, although the details of a particular case make the outcome very difficult to predict, the general idea is a familiar one: a chiral molecule will fit preferentially one way with another molecule, because of its asymmetric shape.
Although you may not be able to predict off the top of your head which enantiomer is formed in a Sharpless epoxidation, given one result, you may be able to guess another. Given the reaction on the left, see what you can tell about the reaction on the right.

Why Do You Need a Personal Auto Grade? The Auto Professor Explains2021-01-082020-12-07https://theautoprofessor.com/wp-content/uploads/2018/10/autoproflogor.pngThe Auto Professorhttps://theautoprofessor.com/wp-content/uploads/2021/01/bigstock-three-generation-hispanic-fami-278663392.jpg200px200px
Personal Auto Grades give you a great advantage over other car safety rating systems. Why is this important to you?
Are you the same driver you were twenty years ago? It's likely that your driving style has changed over the years.
Does your partner drive in the same way that your newly licensed teenager does? Of course not. Teenagers are more likely to be killed by road crashes than anything else.
Does your senior parent have different protection needs from their automobile? Statistically, older drivers are more likely to be injured in a car crash than younger people, so their needs for a safe car are also different.
That's where The Auto Professor comes in. Because we're dedicated to helping you choose the best car to protect each driver, we've created Auto Grades. This easy to understand safety rating empowers you to find the safest car for your specific driver, not just an anonymous car crash dummy.
Introduction to Auto Grades
Auto Grades are car rankings based on real-life crash data, not controlled lab experiments with crash test dummies. They offer unbiased information about how well a car protected real people on real roads and help consumers make meaningful comparisons.
Each Auto Grade considers a vehicle's historical crash experience. This means what really happened to real people in real crashes on real roads; which drivers walked away and which didn't. Using 30 years of extensive auto safety knowledge, data mining expertise, and federal crash statistics, The Auto Professor has evaluated over 4,000 vehicles.
Try it for yourself here and the drivers in your family. Do as many searches as you want for free.
How to Personalize Your Auto Grade
Personalizing your Auto Grade is easy! Simply visit the Auto Grade search page and enter the make, model and year of the car. First, the system generates an overall Auto Grade and explains the reason for that grade.
Next to the Auto Grade search result, you'll see a box labeled "Get Your Personalized Auto Grade." If there's enough data for that car, you can enter your age and gender for an individualized Auto Grade based on that information.
We strongly encourage you to use this feature because not all people are protected equally in all cars. Here's an example:
Automotive safety experts have known for decades that crash outcomes have different results depending on gender and age – but Auto Grades is the only safety rating system that takes those differences into account.
Watch this video for more information about personalizing your Auto Grade.
It is Easy to Compare Vehicle Safety Ratings
Auto Grades are easy to understand, with grades from A to F (just like in school).
Auto Grades is also the only safety rating system that lets you easily compare from among different types of vehicles. Other safety ratings only compare cars of a similar weight and class. Auto Grades, however, grades vehicles compared to all other vehicles, regardless of weight, class, or size, so you can compare subcompacts, midsize sedans, SUVs, and anything between.
Learn more about crash tests and comparing vehicle safety ratings.
The Bottom Line in Personal Vehicle Safety
The bottom line is that not all vehicle safety ratings are created equal and not all drivers are the same. With its easy to understand A-F ranking and real-life data, The Auto Professor gives you the power to make informed decisions when buying a car – with no fine print and no restrictions. The Auto Professor's goal is to create a world where everyone walks away from a crash.
Car safety is personal. Now that you know why you need a personal Auto Grade, use the search bar below to find one for yourself. It's quick, free, and easy to use.
Where does this car accident data come from?
The Auto Professor uses data from the gold standard in car crash statistics: the Fatality Analysis Reporting System (FARS). The data is based on real-life crash information, not controlled lab experiments with crash test dummies. The data has been used by safety researchers to measure how well seatbelts and airbags protect people.
FARS collects data from all fatal traffic accidents in the 50 states, Washington, D.C., and Puerto Rico. Eligible accidents involve motor vehicles traveling on public roads that result in a person's death within 30 days of the crash.
Watch a video about it here.
Why should Auto Grades be personalized?
You need a personal Auto Grade because not all people are protected equally in all cars. Why? Because we become more vulnerable as we age – our vascular system stiffens, our muscles atrophy, and our bones lose density. Also, men and women have different bone structure and musculature, affecting how they respond to physical trauma.
Why don't you have personal Auto Grades for every car?
Sometimes the Fatality Analysis Reporting System, where The Auto Professor gets its data, doesn't always have enough information to create a personalized Auto Grade. This is especially common with newer cars.
How can I improve car safety?
The best way to improve car safety is to choose the right car for the driver. Start with a personal Auto Grade. The Auto Professor's Auto Grades are the only safety ratings that factor in age and gender when creating rankings, so everyone can find the car that's safest for them.

Pundits have been fretting a lot lately about robots leaving humans behind, taking our jobs and possibly a lot more, as in The Matrix and Terminator films. Christof Koch, my go-to source for brain science for 25 years, has proposed a solution. To keep up with machines, we should boost our cognitive powers with brain implants.
Koch notes that brain implants are already helping paralyzed people control computers and robots, and they are being investigated as treatments for depression and other mental disorders. Future implants could help us download huge amounts of information instantly, he claims, so we can learn "novel skills and facts without even trying." Like Neo "learning" how to fly a helicopter in The Matrix!
"Another exciting prospect," Koch says, is "melding two or more brains into a single conscious mind by direct neuron-to-neuron links." Like The Borg in Star Trek! Koch urges a "crash program to design safe, inexpensive, reliable and long-lasting devices and procedures for manipulating brain processes inside their protective shell."
Whoa. A few responses pop into my un-enhanced mind: First, brain-implant pioneers like Jose Delgado and Robert Heath, who were infamous for experimenting on a bull and a gay man, respectively, and whose work I just described on this site, would have loved Koch's proposal. They'd say, Yeah, bring it on! If we had more moola for our research, you'd be living in a neuro-utopia by now!
Second: Koch neglects obvious questions raised by his sci-fi vision. It's scary enough that bad guys can hack into our smart phones and laptops. What if they could hack into our brains? Implants would give Big Brother the ultimate form of mind-reading and mind-control.
Third, and this is my most important point: We are nowhere close to being able to enhance the brain in the manner that Koch envisions. Scientists have been experimenting with neuro-technologies for mental illness for more than half a century, and they have little to show for it.
Reliably integrating neural tissue and digital technologies would require cracking the neural code, the brain's software, which transforms processes in the brain into perceptions, memories, emotions, decisions. It was Koch himself who made me doubt that science will solve the neural code any time soon, if ever.
Koch gave me this skeptical overview of neural-code research more than a dozen years ago. Since then there has been plenty of neuro-hype but no genuine breakthroughs in cracking the neural code. Koch has thrown his weight behind a mind-model called integrated information theory. It implies that even a single proton might be conscious, which means that consciousness pervades the entire cosmos, as decreed by the mystical doctrine panpsychism. Koch's backing of integrated information theory seems to me like a sign of desperation.
So does his call for research aimed at turning us into super-intelligent cyborgs. Koch is perhaps seeking a grand justification for the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a multi-billion-dollar federal program that supports research at the Allen Institute and elsewhere.
Koch is genuinely worried about humanity's future. That was clear when I interviewed him last year in Seattle for a book I'm writing on the mind-body problem. He expressed concern over inequality, political instability, nuclear terrorism and war. He feared that science, far from solving our problems, might exacerbate them.
Artificial intelligence could wreak havoc in other ways. A stock-picking program might goad humans into war to boost the performance of defense-industry stocks. "It doesn't want to take over the world," Koch explained, "it just wants to maximize its return on investment. Law of unintended consequences, happens all the time." Moreover, machines might eventually outsmart us. "It's something to worry about," Koch said.
When Koch and I spoke in Seattle, Donald Trump hadn't even been elected yet. The future scares me too. We're got serious problems on our hands, and we have a lot of work to do to solve them. Brain implants are not the answer.

Having recently launched our Malaysian website, the timing of this event could not have been better.
3 TED Talks to Lead, Motivate and Inspire Employees.
For years, TED (Technology, Entertainment and Design) has given the world access to thought- conversations from some of the greatest minds of our day. Interesting though the videos may be, rarely does a manager have 25 minutes to spare for something that doesn't directly tie into their day-to-day.


Raptor S-Tower is BLHeli-S 4-in-1 ESC, coming with EFM8BB21F16G MCU, support Dshot / Multishot / Oneshot, support high KV motor, can support at most 500k eRPM. And integrated with current meter on the ESC, capable of displaying current with OSD directly in realtime. BLHeli-S firmware is the next generation code, following the base BLHeli code. It designed for superior performance in multirotors, and uses hardware generated motor pwm for smooth throttle response and silent operation.
F3 flight controller, supports PPM, PWM and SBUS remote control / receiving mode.
Dual-way signal transmissin method to connect the flight controller and ESC greatly guarantee the signal stability.
The code supports regular 1-2ms pulse width input, as well as Oneshot125 , Oneshot42 and Multishot . The input signal is automatically detected by the ESC upon power up.
Why should we choose the raptor 390 tower for the drones?
2. The Tower structure design could protect the ESC well during the flight.ESC is one of the most easily broken parts on the drones except the propellers.According to our experience,some of the ESC were damged by the propeller rotation or tree brunch cut after the damage when it installed on top of the motor arm.Some of the ESC were damaged due to the broken of the motor arm during the crash.For this tower, the esc integrated in the tower which installed in the middle of the quad frame, the ESCs can be protected quite well.
3. Raptor 390 tower makes the assembling of the fpv racing drones more and more convenient,the wires tidy and concise.Using this tower, you just need to solder the 4 motor wries to the holes, so easy. The lower board integrated the 4in1 ESC,the power port is in the center,bulge a bit over. This could not only make the connecting wires more convenient, but also avoid to interrupt the esc output port on the two sides. The upper board F3 flight controller board integrated with the OSD. There is also 5V,12V and BATV for powering the camera,video tx,LED and other euipements.
4. Small size and light weight tower fit for all sizs of the quad,and make the center of gravity of the drone lower. The weight of the raptor 390 tower is only 22g, with two layers tower structure, the height is only 15.1mm. Therefore, the tower can be installed on the 130mm to 330mm size of quads easily.
