Development and Research of Ion Optics Digital Simulation System for EI Source

Zhipu Xuebao
The ion optical system is an important component of electron impact (EI) ion source, which uses electrostatic lens to extract ions in the ion chamber, further focus, accelerate and shape, and regulate the speed and energy of the ion beam. The performance

Research on four-coil structure of magnetically coupled resonant wireless power transmission system

Gong-kuang zidonghua, 2019
For the position of four coils of traditional four-coil magnetically coupled resonant wireless power transmission system is relatively fixed and cannot be changed at will, which leads to limitation of its use, a new four-coil structure was proposed ...

Adaptive Subcarrier PSK Intensity Modulation in Free Space Optical Systems [PDF]

, 2010
We propose an adaptive transmission technique for free space optical (FSO) systems, operating in atmospheric turbulence and employing subcarrier phase shift keying (S-PSK) intensity modulation.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Efficient algorithms for optimal video transmission [PDF]

Proceedings DCC '98 Data Compression Conference (Cat. No.98TB100225), 2002
This paper addresses the problem of sending an MPEG-encoded video stream over a channel of limited bandwidth. When there is insufficient bandwidth available for the rate at which the sequence was encoded, some data must be dropped. In this paper we give fast algorithms to determine a prioritization of the data that optimizes the visual quality of the ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Efficiency of three-terminal thermoelectric transport under broken-time reversal symmetry

, 2013
We investigate thermoelectric efficiency of systems with broken time reversal symmetry under a three-terminal transport. Using a model of Aharonov-Bohm interferometer formed with three noninteracting quantum dots, we show that Carnot efficiency can be ...

The Impact of QoS Constraints on the Energy Efficiency of Fixed-Rate Wireless Transmissions [PDF]

, 2008
Transmission over wireless fading channels under quality of service (QoS) constraints is studied when only the receiver has channel side information. Being unaware of the channel conditions, transmitter is assumed to send the information at a fixed rate.
