Is malaria messaging working? African biostatisticians have the data

University of the Witwatersrand
Peer-Reviewed Publication

New analysis from SSACAB shows malaria messaging works. Using advanced causal methods, Edson Mwebesa found that exposure to prevention messages increases insecticide-treated net use among women and children in Uganda, offering rare causal evidence to guide policy.

How personalized algorithms lead to a distorted view of reality

Ohio State University
Peer-Reviewed Publication

The same personalized algorithms that deliver online content based on your previous choices on social media sites like YouTube also impair learning, a new study suggests. Researchers found that when an algorithm controlled what information was shown to study participants on a subject they knew nothing about, they tended to narrow their focus and only explore a limited subset of the information that was available to them.

Deep MARL-based resilient motion planning for decentralized space manipulator

Beijing Institute of Technology Press Co., Ltd

Space manipulators play an important role in the on-orbit services and planetary surface operation whose reliability is a key issue. In the extreme environment of space, space manipulators are susceptible to a variety of unknown disturbances. Since it is difficult for the manipulator to be repaired immediately, once it fails, it will mean that it cannot complete the mission as expected, which may cause serious losses and dangers. How to have a resilient guarantee, i.e., the manipulator’s ability to resiliently recover and continue to complete tasks, in failure or disturbance is the core capability of its future development. The motion planning unit is used as the computing terminal of the manipulator’s joint motion trajectory. Compared with traditional motion planning, learning-based motion planning has gradually become a hot spot in current research. However, no matter what kind of research ideas, the single robotic manipulator is studied as an independent agent, making it unable to provide sufficient flexibility under conditions such as external force disturbance, observation noise, and mechanical failure.

Minimum-time control for the test mass release phase of drag-free spacecraft

Beijing Institute of Technology Press Co., Ltd

The gravitational wave is a prediction of the general theory of relativity that can be detected by measuring the relative distance between two test masses (TM) along the geodesics. The TM is fixed by the cage and vent mechanism to avoid collision with the spacecraft cavity during launch. Once the drag-free spacecraft reaches its target orbit, the TM must be released by the grabbing positioning and release mechanism (GPRM) to the cage center of the inertial sensor in a limited amount of time. The capture of the TM by means of the electrostatic suspensions is crucial for the mission. However, the GPRM inevitably generates large release errors and the low electrostatic force makes the TM capture control a difficult task. Moreover, the experimental results of the LISA Pathfinder mission have shown that the TM release velocities were well higher than the ones expected. The previous robust sliding mode controller needs to be optimized.

Johns Hopkins team breaks through quantum noise

Johns Hopkins University Applied Physics Laboratory
Peer-Reviewed Publication

A team from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore has broken new ground in understanding quantum noise — a major source of error in quantum computing. Their findings, published in Physical Review Letters, address a critical challenge that must be solved to develop useful quantum computers.

For young children, finger-counting a stepping stone to higher math skills

American Psychological Association
Peer-Reviewed Publication

Children who count on their fingers between ages 4 and 6 1/2 have better addition skills by age 7 than those who don’t use their fingers, suggesting that finger counting is an important stepping stone to higher math skills, according to research published by the American Psychological Association.
