A federal watchdog is recommending that ousted vaccine expert Rick Bright be reinstated while it investigates whether the Trump administration retaliated against his whistleblower complaints when it removed him from a key post overseeing the coronavirus response, Bright's lawyers said Friday.
The notoriously independent-minded federal judge who once said he was disgusted by the conduct of Michael Flynn could block the administration's bid to drop criminal charges against the former adviser to President Donald Trump, legal experts said.
Consider that $u_0$ nodes are aware of some piece of data $d_0$. This note derives the expected time required for the data $d_0$ to be disseminated through-out a network of $n$ nodes, when communication between nodes evolves according to a graphical Markov model $overline{ mathcal{G}}_{n,hat{p}}$ with probability parameter $hat{p}$. In this model, an edge between two nodes exists at discrete time $k in mathbb{N}^+$ with probability $hat{p}$ if this edge existed at $k-1$, and with probability $(1-hat{p})$ if this edge did not exist at $k-1$. Each edge is interpreted as a bidirectional communication link over which data between neighbors is shared. The initial communication graph is assumed to be an Erdos-Renyi random graph with parameters $(n,hat{p})$, hence we consider a emph{stationary} Markov model $overline{mathcal{G}}_{n,hat{p}}$. The asymptotic "$u_0$-expected flooding time" of $overline{mathcal{G}}_{n,hat{p}}$ is defined as the expected number of iterations required to transmit the data $d_0$ from $u_0$ nodes to $n$ nodes, in the limit as $n$ approaches infinity. Although most previous results on the asymptotic flooding time in graphical Markov models are either emph{almost sure} or emph{with high probability}, the bounds obtained here are emph{in expectation}. However, our bounds are tighter and can be more complete than previous results.
We empirically evaluate an undervolting technique, i.e., underscaling the circuit supply voltage below the nominal level, to improve the power-efficiency of Convolutional Neural Network (CNN) accelerators mapped to Field Programmable Gate Arrays (FPGAs). Undervolting below a safe voltage level can lead to timing faults due to excessive circuit latency increase. We evaluate the reliability-power trade-off for such accelerators. Specifically, we experimentally study the reduced-voltage operation of multiple components of real FPGAs, characterize the corresponding reliability behavior of CNN accelerators, propose techniques to minimize the drawbacks of reduced-voltage operation, and combine undervolting with architectural CNN optimization techniques, i.e., quantization and pruning. We investigate the effect of environmental temperature on the reliability-power trade-off of such accelerators. We perform experiments on three identical samples of modern Xilinx ZCU102 FPGA platforms with five state-of-the-art image classification CNN benchmarks. This approach allows us to study the effects of our undervolting technique for both software and hardware variability. We achieve more than 3X power-efficiency (GOPs/W) gain via undervolting. 2.6X of this gain is the result of eliminating the voltage guardband region, i.e., the safe voltage region below the nominal level that is set by FPGA vendor to ensure correct functionality in worst-case environmental and circuit conditions. 43% of the power-efficiency gain is due to further undervolting below the guardband, which comes at the cost of accuracy loss in the CNN accelerator. We evaluate an effective frequency underscaling technique that prevents this accuracy loss, and find that it reduces the power-efficiency gain from 43% to 25%.
The interoperability of proof assistants and the integration of their libraries is a highly valued but elusive goal in the field of theorem proving. As a preparatory step, in previous work, we translated the libraries of multiple proof assistants, specifically the ones of Coq, HOL Light, IMPS, Isabelle, Mizar, and PVS into a universal format: OMDoc/MMT.
Each translation presented tremendous theoretical, technical, and social challenges, some universal and some system-specific, some solvable and some still open. In this paper, we survey these challenges and compare and evaluate the solutions we chose.
We believe similar library translations will be an essential part of any future system interoperability solution and our experiences will prove valuable to others undertaking such efforts.

An execution environment may have a monitoring, analysis, and feedback loop that may configure and tune the execution environment for currently executing workloads. A monitoring or instrumentation system may collect operational and performance data from hardware and software components within the system. A modeling system may create an operational model of the execution environment, then may determine different sets of parameters for the execution environment. A feedback loop may change various operational characteristics of the execution environment. The monitoring, analysis, and feedback loop may optimize the performance of a computer system for various metrics, including throughput, performance, energy conservation, or other metrics based on the applications that are currently executing. The performance model of the execution environment may be persisted and applied to new applications to optimize the performance of applications that have not been executed on the system.
An electronic device with one or more processors, memory and a display receives a first request to display a first video stream on the display. In response to receiving the first request, the electronic device displays the first video stream on the display. While displaying the first video stream on the display, the electronic device receives a second request to display a second video stream on the display. In response to receiving the second request, the electronic device displays at least a portion of the first video stream on the display concurrently with at least a portion of the second video stream, where the second video stream was received, at least in part, from a content source in response to a request from the electronic device to the content source for delivery of the second video stream from the content source.

Shooters must presently take their firearms out of their hands to then manually actuate a new target into shooting position. This Target Apparatus will allow the shooter to shine his laser light, infrared light, flashlight, or multi-spectrum light onto a Target Apparatus-mounted sensor that engages a drive means mounted upon the target frame that then forwards a new target into position without removing the firearm from its' shooting position. The unit also uses a unique target backing material that does not require targets to be made of rolls of coated or heavy material stock. The system can utilize rolls of cash register paper, cut sections of gift wrapping paper, hand towel rolls, or even paper towels as target materials without snagging and preventing the next target from being presented.
A method of providing a user with an extra-terrestrial somatosensory experience includes equipping the user with an underwater breathing apparatus, having the user occupy an underwater environment, such environment providing buoyancy to the user, and while the user occupies the underwater environment, using a computer-implemented virtual reality system to present to the user a virtual reality environment modeling an extra-terrestrial setting. The virtual reality system inhibits visual perception by the user of items outside of the virtual reality environment so that the user experiences the virtual reality environment under a buoyancy condition provided by the underwater environment. The buoyancy condition enhances the experience of the virtual reality environment.
This is a scalable water cleansing system intended for very low technology primitive communities buildable for between $600 and $1,000 of parts. A gravity feed system is contemplated with one or more of an initial filtering stage(s), a settling stage, a UV treatment stage, and an ozonator stage. A stand-alone power system with solar power needing no infrastructure is contemplated to enhance purification. The system can improve the worst of water quality, including for small groups; and under some conditions to end up with clean water of a quality found in developed countries with mature water systems. For water to the site in communities with low precipitation, the water brought in would be emptied into the initial stage of the water cleansing system, and the person who brought the water would draw from the last stage most or all of the amount of water carried in.

An intelligent bionic expectoration system and a three-way device thereof. The intelligent bionic expectoration system includes a negative pressure suction module, a central processing module, a patient interface unit and a respiratory muscle synchronous motion module. The central processing module controls two valves to open or close, closing one valve while opening another valve, and controls the respiratory muscle synchronous motion module. The patient interface unit is connected to the positive pressure ventilation module and the negative pressure suction module, allowing positive or negative pressure airflow to flow by, depending on which valve is open, so as to allow airflow to flow in or out of the lung. The respiratory muscle synchronous motion module can employ nerve stimulation and mechanical pushing, and acts synchronously as the airflow moves, thereby simulating human coughing and achieves bionic expectoration.
An example method for detecting respiratory disturbances experienced by a subject can include receiving an airflow signal and at least one of an acoustic or vibration signal, where the airflow, acoustic, and/or vibration signals are associated with the subjects breathing. At least one feature can be extracted from the airflow signal and at least one feature can be extracted from at least one of the acoustic or vibration signal. Based on the extracted features, at least one respiratory disturbance can be detected. The respiratory disturbance can be flow limited breath or inspiratory flow limitation (“IFL”).

As of Friday in Texas, you can go to a tanning salon. In Indiana, houses of worship are being allowed to open with no cap on attendance. Places like Pennsylvania are taking a more cautious approach, only starting to ease restrictions in some counties based on the number of COVID-19 cases. By Monday, at least 31 states will have partially reopened after seven weeks of restrictions. The moves come as President Trump pushes for the country to get back to work despite public health experts warning that it's too soon. "The early lesson that was learned, really, we learned from the island of Hokkaido in Japan, where they did a really good job of controlling the initial phase of the outbreak," said Bob Bednarczyk, assistant professor of global health and epidemiology at the Rollins School of Public Health at Emory University in Atlanta. Because of that success, many of the restrictions on the island were lifted. But cases and deaths surged in a second wave of infections. Twenty-six days later

As Governor Roy Cooper’s order to ease restrictions takes effect later this week, 29 state parks will reopen to the public on Saturday, May 9th. That includes Fort Macon, which is one of the most visited state parks each year. “Our main goal is to give people access to the park without it getting too crowded,” said Katie Hall, the Public Information Officer for the North Carolina Division of Parks and Recreation. Fort Macon State Park closed almost seven weeks ago because of the COVID-19 pandemic. On Saturday, beach areas, trails, and restrooms will reopen to the public. However, the visitors center and the exhibit will remain closed. Hall said park rangers are expecting a record number of visitors this weekend, surpassing park visitation numbers during the Memorial Day, Labor Day, and Independence Day holidays. “We’re not really opening the park for people to hang out. The idea is to get to the park, get some fresh air, get some exercise, run on the beach, whatever you like to do, and

The Mayors of DeKalb and Rockford responded to the statewide minimum wage hike that was signed into law last week. The measure will raise the state's minimum wage to $15 per hour by 2025. DeKalb Mayor Jerry Smith worries about the effect this may have on small businesses. Smith says he would have preferred that the increase be done more incrementally. "I would have liked to have seen something that was written into law that mandated perhaps a one or two year step, and then let's take a look at it," he said. "You know, economies change." But he says the law taking effect means businesses know what to expect. "If you know that you're going to be paying nine and a quarter next year and ten the following year, or whatever the case may be, the smart businesses -- small or large -- are going to make those adjustments that are necessary so the bottom line is still black," he said. Smith says the City of DeKalb already pays its employees at a level where the wage hike's effect on city
