# sec: oops! 5G, a European dilemma (the 1st one of a series): the quiet spread of Huawei

<< China's Huawei has quietly become a leading supplier of the backbone equipment for mobile networks, particularly in developing markets thanks to cheaper prices. >>

<< Each year it invests between 10 and 15 percent of its sales revenue on research and development. It spent $13.8 billion on R&D  (Research and development) in 2017 and $15 billion last year. >>

<< It's a dilemma for European telecoms firms: Should they steal a march on competitors and rapidly roll out next-generation 5G mobile networks using equipment from top supplier Huawei? Or should they heed US-led warnings of security threats and sit tight, and possibly fall behind? >>

<< Huawei strenuously denies its equipment could be used for espionage. >>

<< Deutsche Telekom, in an internal document obtained by Bloomberg, warned that Europe could fall behind China and the United States by as much as two years if it forgoes using Huawei's 5G equipment. >>

# ai.bot: organizations can help keep workers productive and happy with AI "superminds", by Thomas.

<< Malone (Thomas Malone is a professor of management at MIT’s Sloan School of Management, founder and director of the MIT Center for Collective Intelligence) predicts that AI, robotics, and automation will destroy many jobs-including those of high-skilled knowledge workers-while at the same time creating new ones. By investing in the right kinds of AI, he says, organizations can help keep workers productive and happy-and make sure our “superminds” are actually smarter than our regular minds. >>

# acad: oops! 78.1% of biomed. sci. studies use only parametric tests ...

<< Transparent reporting is essential for the critical evaluation of studies. However, the reporting of statistical methods for studies in the biomedical sciences is often limited. >>

<< Nonparametric tests, such as the Mann-Whitney U test, Wilcoxon sign rank test and Kruskal Wallis test, may sometimes be preferable as sample sizes in basic biomedical science research are often too small to determine the data distribution. However, these tests are not commonly used. A systematic review of physiology studies showed that 3.8% used only non-parametric tests to compare continuous data, 13.6% used a combination of parametric and non-parametric tests, and 78.1% of studies used only parametric tests >>

# ai: DeepMind - AlphaStar wins almost every match against Pro StarCraft II players

<< Humans tend to think we’re adept at the games we create, but computers have proven time and time again that we’re just not fast enough to stay on top. >>

<<  AlphaStar is a convolutional neural network (..) Through intensive training with competing models, DeepMind was able to teach AlphaStar how to play the game as well as the best human players. (..)  AlphaStar has substantially lower APM (actions per minute) compared with the human players, but it’s making smarter choices. >>

# evol: a ghost archaic ancestor was identified with deep learning

<< All modern humans are genetically related to each other at a time depth of up to 300 thousand years ago and share a common African root. >>

<< Sequencing of ancient Neanderthal and Denisovan fossils supported introgression events into AMH (Anatomically Modern Humans) out of Africa; however, recent studies also support the presence of gene flow from AMH into Neanderthals, thus suggesting a complex hominin evolution. >>

AA << results support a third introgression in all Asian and Oceanian populations from an archaic population. This population is either related to the Neanderthal-Denisova clade or diverged early from the Denisova lineage. >>

# brain: a way to prevent over-firing NMDA receptors ... "it really comes down to chemistry"

<< The ideal drug is one that only affects the exact cells and neurons it is designed to treat, without unwanted side effects. This concept is especially important when treating the delicate and complex human brain. Now, scientists at Cold Spring Harbor  Laboratory have revealed a mechanism that could lead to this kind of long-sought specificity for treatments of strokes and seizures. >>

# behav: outrage does not make revolution

<< If you're angry about the political feud that drove the federal government to partially shut down, or about a golden parachute for a CEO who ran a business into the ground, you aren't alone-but you probably won't do much about it, according to new research by Carnegie Mellon University's Tepper School of Business. >>

<< Across four experiments, (AA) show that people respond quite differently to correct these two types of injustices. When bad things happen to good people, individuals are eager to compensate a good person’s losses, but only do so to a small degree. In contrast, when a good thing happens to a bad person, because the only perceived appropriate act of punishment is to fully strip the bad actor of all his or her illegitimate gains, few people choose to punish in this costly way. However, when they do, they do so to very large degrees. Moreover, we demonstrate that differential psychological mechanisms drive this asymmetry. >>
