Beneits and Costs of Uniqueness in Multiple Object Tracking: The Role of Object Complexity

The multiple-object tracking(MOT)paradigm has been widely used as a tool for studying attention and visual cognition.Although typical MOT tasks have employed identical objects as tacking stimuli,people usually track unique objects in real-world situations,like basketball point guard being aware of where every teammate and opponent is.Then,how do unique objects affect multiple-object tracking?Recent research has catalogued seemingly contradictory findings,varying from enhanced to impaired tracking performance.

Molecular mechanism of horsefly’s antithrombotic effect

Horseflies are a blood-feeding arthropod, notorious as a common pest of animals and sometimes of humans. While a target of the biological control in green farming and animal husbandry, dried bodies of the females, known as mangchong, are used in traditional Chinese medicine (TCM) to treat cardiovascular diseases. Although the unique drug is believed to contain various bioactive substances, little has been known about its biochemical functions in the secretion of the insect's salivary glands and, in parti...     

Level pinning of anti-PT-symmetric circuits for efficient wireless power transferOA

Wireless power transfer(WPT) technology based on magnetic resonance(a basic physical phenomenon)can directly transfer energy from the source to the load without wires and other physical contacts, and has been successfully applied to implantable medical devices, electric vehicles, robotic arms and other fields.However, due to the frequency splitting of near-field coupling, the resonant WPT system has some unique limitations, such as poor transmission stability and low efficiency. Here, we propose...     

For ESA and China,“the Most Interesting Collaboration Is Yet to Start on HXMT”

正HXMT will be China’s first astronomical satellite.It will study X-rays from objects such as black holes,neutron stars and the remains of exploded stars.These are exciting topics that are of interest to scientists from all over the world.HMXT will join a number of X-rays satellites already in operation such as ESA’s XMMNewton.Each mission has its own strengths and for     

Paleo-ecosystem Sealed in Amber: Paleobiota from Lower Eocene of Fushun,Northeastern China

<正>Amber-bearing deposits are among the most important Konservat-Lagersttten providing unique windows into past ecosystems.Fushun amber has been known for over a century and was traditionally regarded as an important source of medicine as well as organic gemstones.The inclusions,however,were not the subject of any comprehensive investigation     

Turtle before Turtles

正People are familiar with modern turtles, but the evolution of turtles remains one of the biggest mysteries in paleontology. The turtle has a unique body form of tetrapods (four-leg vertebrates,or vertebrates except fishes, such as lizards/crocodiles,birds, and mammals). It has a shell composed of     

Researchers Identify a Novel Mechanism That Regulates Germline Stem Cell Function in Drosophila

正In adult tissues,stem cells are defined by their unique capacity to self-renew and produce nonequivalent daughters that can differentiate into cell lineages to maintain tissue homeostasis.Misregulation of stem cell functions has been implicated in a variety of human diseases such as degenerative diseases and cancer.Thus,understanding the regulatory mechanisms     

Modulation “A Clever Way of Observing X-ray Sky”

正With the launch of HXMT,China is starting its exciting program of observations of our Galaxy and the deep Universe in the X-ray band.This is particularly interesting as the high-energy channel provides detailed and unique information about cosmic sources where extreme physical conditions and strong gravity are at work.     

New Measurements Suggest "Antineutrino Anomaly" Fueled by Modeling Error

<正>Results from a new scientific study may shed light on a mismatch between predictions and recent measurements of ghostly particles streaming from nuclear reactors—the so-called"reactor antineutrino anomaly,"which has puzzled physicists since 2011.The anomaly refers to the fact that scientists tracking the production of antineutrinos—emitted as a

China＇s First Satellite Tracking of Migration Route of Black-necked Cranes

Teaming up with colleagues at home and abroad.CAS scientists launched China‘s first ever satellite tracking project on Black-neeked Cranes in late February at the National Dashanbao Black-necked Crane Natural Reserve in southwest China‘s Yunnan Province.Its objective is to understand the migration route of the crane‘s eastern population so as to better protect this rare species.     

Pragmatic Analysis of Internet Relay Chat

in Internet relay chat too. Introduction Although a number of linguists such as Baron (2000), Crystal (2001) and Hillier (2004) have begun to explore and describe some of the changes in function and form of written language as a consequence of technological developments and the rise of the internet, computer mediated communication is still relatively less explored. As for the pragmatic interpretation of Internet chat, much less work has been done. This paper is a study of conversational patt…
