It's simple to use data to determine how many undocumented infections there are and the adequate reproductive number. A compartmental model includes asymptomatic and presymptomatic contagions, which can be used to figure out how many unreported infections there are and the proper reproductive number.

Crows are self-aware like humans and have their own form of the human cerebral brain.

Plain Jane was founded with the goal of making CBD hemp flower products more accessible and cheap to the general public. There are now over 75,000 customers spread over practically the entire United States. The goal is to give the greatest CBD flower at the best costs to customers.

To assess COVID-19 transmission, researchers used a Bayesian framework and integrated estimates of the total number of daily cases with data on daily laboratory-confirmed cases to determine the daily reporting ratio.

The most difficult challenge facing modern scientists is predicting COVID-19 multiple waves.

Artificial neural systems trained using supervised, unsupervised, and reinforcement learning all acquire internal representations of high dimensional input. To what extent these representations depend on the different learning objectives is largely unknown.

Recent studies have shown that convolutional neural networks (CNNs) are not the only feasible solution for image classification. Furthermore, weight sharing and backpropagation used in CNNs do not correspond to the mechanisms present in the biological visual system. To propose a more biologically plausible solution, we designed a reward modulated locally connected spiking neural network (SNN) trained using spike-timing-dependent plasticity (STDP) and its reward-modulated variant (R-STDP) learning rules.

Taking preventative actions to lower the probability of a pandemic would cost around 500 times less than reacting to a pandemic.

The US and Soviet forces have trained and deployed marine dolphins for various purposes. Military dolphins have been taught to rescue lost naval swimmers, protect military ships from enemy divers, discover mines for later removal by divers, and assist in locating and recovering equipment lost at sea.

Young scientists are critical for the growth of research and the development of the world's economic system. Despite this, they continue to confront obstacles to success that force them to relocate or even give up on their research careers.

Animals move in three dimensions (3D). Thus, 3D measurement is necessary to report the true kinematics of animal movement. Existing 3D measurement techniques draw on specialized hardware, such as motion capture or depth cameras, as well as deep multi-view and monocular computer vision.

Over the past decade, cryogenic electron microscopy (cryo-EM) has emerged as a primary method for determining near-native, near-atomic resolution 3D structures of biological macromolecules. Automated approaches to improve throughput and efficiency while lowering costs are needed to meet the increasing demand for cryo-EM. Currently, in the process of collecting high-magnification cryo-EM micrographs, data collection requires human input and manual tuning of parameters, as expert operators must navigate low- and medium-magnification images to find good high-magnification collection locations.

Brain activity can be measured using magnetic fields located at some distance from the brain, a technique called magneto-encephalography (MEG). The origin of such magnetic fields are the ionic currents involved in neuronal activity. While these processes are well known at the microscopic scale, it is less clear how large populations of neurons generate magnetic fields.

Here’s the sort of polling Democrats haven’t seen much of in a few weeks. Rep. Larry Kissell (D-N.C.), a freshman who rode into a western North Carolina

The Church and Pike committees of the 1970s exposed CIA lawlessness; created modern legal and congressional intelligence oversight structures; and cleaved the CIA’s history into before and after periods.

The 51-year-old ultra-conservative group, once ostracized by the right, is co-sponsoring the 2010 Conservative Political Action Conference. JBS will have a

Unusual for legislation under such long consideration, substantive portions of the bill remain the subject of intense debate.

Cass Sunstein's nomination has sparked significant debate. Join us as we explore the criticisms he faces from conservative circles.
