Subglacial water bodies are critical components in analyzing the instability of Antarctic ice sheet. Their detection and identification normally rely on geophysical remote sensing methods such as airborne radar echo sounding (RES), ground seismic, satellite/airborne altimetry gravity surveys. In particular, RES surveys able to detect basal terrain with a relatively high accuracy that can assist...

Faradaic electrochemical impedance spectroscopy (f-EIS) in the presence of redox reagent, e.g., [Fe(CN)₆]3-/4-, is widely used in biosensors owing to its high sensitivity. However, in sensors detecting amyloid beta (Aβ), the redox reagent can cause the aggregation of Aβ, which is a disturbance factor in accurate detection. Here, we propose an interdigitated microelectrode (IME) based f-EIS tech...

Since Gallager, Humblet and Spiru first introduced the distributed Minimum Spunning Tree problem, many authors have suggested ways to enhance their basic algorithm to improve its performance. Most of these improved algorithms have even been shown to be very eficient i n terms of reducing their worst-case communications and/or t ime complexity measures. In this paper, however, we take a differen...

the problem, a relocation protocol by an object reloMobile Cache Protocol (MCP) was proposed as a relocation protocol of a replicated object i n a widely distributed object system. MCP has four basic features; relocating a replicated object, 2 optimistic update methods, object reservation and object sharing. To calculate relocation funct ion, M C P uses processing t ime of the object at a candi...

Abstract Low Gain Avalanche Detectors (LGAD) for the High-Granularity Timing Detector (HGTD) are crucial in reducing pileups High-Luminosity Large Hadron Collider. Numerous studies have been conducted on bulk irradiation damage of LGADs. However, few carried out surface LGAD sensors with shallow carbon implantation. In this paper, IHEP-IME LGADs implantation were irradiated up to 2 MGy using ga...

Abstract The geometric structure of supernova remnants (SNR) provides a clue to unveiling the pre-explosion evolution their progenitors. Here we present an X-ray study N103B (0509–68.7), Type Ia SNR in Large Magellanic Cloud, that is known be interacting with dense circumstellar matter (CSM). Applying our novel method for feature extraction deep Chandra observations, have successfully resolved ...

Clustering techniques are usually used in pattern recognition, image segmentation and object detection. For N patterns and k centers each with M features, i n this paper, we first design an O ( k M ) time optimal parallel algorithm for one pass process of clustering with the Ic-means method on a linear array of processors with a wider bus network using N I + ; processors with one bus network, w...

Two n e w modes of real-t ime collision avoidance are presented wh.ich aid in the e.ffectiveness of remote tele-operation. S t i cky coll ision mode improves s y s t e m safety by disallowing contact wi th modelled obstacles. Slippery mode is used t o improve the eff iciency of -the process by reducing t h e required level of operator skill. B o t h modes execute an real-t ime and have been amp...

Random sampling i s a powerful way t o gather informat ion about a group by considering only a small part of it. W e give a paradigm f o r applying this technique to optimization problems, and demonstrate its effectiveness o n matroids. Matroids abstractly model many optimization problems that can be solved by greedy methods, such as the minimum spanning tree ( M S T ) problem. Our results have...
