Emotional arousal enhances perception and memory of high-priority information but impairs processing of other information. Here, we propose that, under arousal, local glutamate levels signal the current strength of a representation and interact with norepinephrine (NE) to enhance high priority representations and out-compete or suppress lower priority representations. In our "glutamate amplifie...

I review the current constraints on the nature of the hotspots of FRII radio sources, and the physical conditions that obtain in them. New Chandra observations suggest that the majority of X-ray detections of hotspots are due to inverse-Compton processes, with magnetic field strengths close to the standard equipartition/minimumenergy values. However, a few broad-line objects have X-ray emission...

This paper is to explore new ways to better understand urban system emphasizing on detection and analysis of urban area hotspots through cell phone traffic data. Firstly, according to the characteristics of GSM network, Voronoi cellular network is introduced to determine the service area of the base station. Then two visualization methods are discussed through analyzing the distribution of cell...

Single-molecule surface-enhanced Raman spectroscopy (SERS) has attracted increasing interest for chemical and biochemical sensing. Many conventional substrates have a broad distribution of SERS enhancements, which compromise reproducibility and result in slow response times for single-molecule detection. Here we report a smart plasmonic sensor that can reversibly trap a single molecule at hotsp...

A large number of hprt-mutants were obtained by treating human lymphoblast cells (TK6) with 5 microM K2Cr2O7 for 5 hr and selecting by growth in 6-thioguanine. A combination of high fidelity polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE) allowed us to measure mutant frequencies as a function of DNA sequence. Chromium(VI) induced four hotspots in a 104 bp doma...

As minimum feature sizes shrink, unexpected hotspots appear on wafers. Therefore, it is critical to detect and fix these hotspots at design stage to reduce development time and manufacturing cost. Currently, the most accurate approach to detect such hotspots is lithography simulation. However, it is known to be time-consuming. This paper proposes a new hotspot detection method with both a regre...

Introduction: Cassini ISS imaged the surface of Io in eclipse by Jupiter in late 2000 and early 2001 and obtained multiple-filter images over timescales of hours. Images like these have been used to study the temperature and variability of the numerous hotspots on the surface [1, 2, 3]. For example, Pele was found to be an active lava lake with most likely basaltic lava composition [2]. New Hor...

Concentrations of biodiversity, or hotspots, represent conservation priorities in terrestrial ecosystems but remain largely unexplored in marine habitats. In the open ocean, many large predators such as tunas, sharks, billfishes, and sea turtles are of current conservation concern because of their vulnerability to overfishing and ecosystem role. Here we use scientific-observer records from pela...

Spatial analyses of ecosystem system services that are directly relevant to both forest management decision making and conservation in the subtropics are rare. Also, frameworks that identify and map carbon stocks and corresponding forest management drivers using available regional, national, and international-level forest inventory datasets could provide insights into key forest structural char...
