Physicists bring human-scale object to near standstill, reaching a quantum state（图）
量子态 引力 原子尺度
2023/6/19
To the human eye, most stationary objects appear to be just that — still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, wha...

Low-temperature plasmas offer promise for applications in medicine, water purification, agriculture, pollutant removal, nanomaterial synthesis and more. Yet making these plasmas by conventional method...
Epidemic Variability in Hierarchical Geographical Networks with Human Activity Patterns
Epidemic Variability Hierarchical Geographical Networks Human Activity Patterns Social and Information Networks
2012/4/19
Recently, some studies have revealed that non-Poissonian statistics of human behaviors stem from the hierarchical geographical network structure. On this view, we focus on epidemic spreading in the hi...
Empirical analysis of collective human behavior for extraordinary events in blogosphere
Empirical analysis collective human behavior extraordinary events blogosphere
2011/8/11
Abstract: To explain collective human behavior in blogosphere, we survey more than 1.8 billion entries and observe statistical properties of word appearance. We first estimate the basic properties of ...

In this paper the modified Schrodinger equation for attosecond laser pulses interaction with 揳toms?of human brain . i.e. neurons is developed and solved. Considering that the mass of the human ...
Human as Real-Time Sensors of Social and Physical Events: A Case Study of Twitter and Sports Games
Real-Time Sensors Social Physical Events Twitter Sports Games Case
2011/9/14
In this work, we study how Twitter can be used as a sensor to detect frequent and diverse social and physical events in real-time. We devise efficient data collection and event recognition solutions t...
Impact of Heterogeneous Human Activities on Epidemic Spreading
Epidemic Spreading, Human Dynamics, Inter-Event Time Distribution, Susceptible-Infected Model, Heterogeneity
2011/9/2
Recent empirical observations suggest a heterogeneous nature of human activities.The heavy-tailed inter-event time distribution at population level is well accepted,while whether the individual acts i...

Preliminary Results of an Instrument for Measuring the Optical Aberrations of the Human Eye
the Optical Aberrations the Human Eye
2010/10/27
The human eye, as our biological vision instrument, contains intrinsic optical defects, referred to as optical aberrations or ametropia. The immediate consequence of such aberrations is poor quality o...
