Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, EarlyView., 2023
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

A Combinatorial Analysis of Recent Attacks on Step Reduced SHA-2 Family [PDF]

, 2008
We perform a combinatorial analysis of SHA-2 compression function. This analysis explains in a unified way the recent attacks against reduced round SHA-2. We start with a general class of local collisions and show that the previously used local collision

Synthesis of Second-Generation Analogs of Temporin-SHa Peptide Having Broad-Spectrum Antibacterial and Anticancer Effects

Antibiotics
Antimicrobial peptides (AMPs) are a promising class of therapeutic alternatives with broad-spectrum activity against resistant pathogens. Small AMPs like temporin-SHa (1) and its first-generation analog [G10a]-SHa (2) possess notable efficacy against ...

AuCu@CuO2 Aerogels with H2O2/O2 Self‐Supplying and Quadruple Enzyme‐Like Activity for MRSA‐Infected Diabetic Wound Management

Advanced Science, EarlyView.
The AuCu@CuO2 aerogels demonstrate favorable photothermal properties, four types of enzyme‐like activities, and H2O2/O2 self‐supplying to modulate the complex microenvironment of MRSA‐infected diabetic wounds. The results indicate that the AuCu@CuO2 aerogel can be activated by the microenvironment of diabetic wound infection, alleviating inflammation ...

deepTFBS: Improving within‐ and Cross‐Species Prediction of Transcription Factor Binding Using Deep Multi‐Task and Transfer Learning

Advanced Science, EarlyView.
DeepTFBS leverages deep learning to predict transcription factor binding sites across species, integrating multi‐task and transfer learning approaches to improve performance in data‐scarce scenarios. This study demonstrates enhanced accuracy in intra‐ and cross‐species prediction, revealing conserved regulatory patterns and functional variants.

An Effective Privacy-Preserving Data Coding in Peer-To-Peer Network

, 2018
Coding Opportunistically (COPE) is a simple but very effective data coding mechanism in the wireless network. However, COPE leaves risks for attackers easily getting the private information saved in the packets, when they move through the network to ...

Asymmetric Intramolecular α‐Arylation of Polar Amino Acids Bearing β‐Leaving Groups

Angewandte Chemie, EarlyView.
Use of enolate chemistry to functionalise amino acids with β‐heteroatom side‐chains (serine, cysteine, threonine, etc.) is hampered by β‐elimination. We show that α‐arylation can be achieved by incorporating the side chain into a saturated heterocycle, making the unwanted elimination a disfavoured 5‐endo‐trig reaction.

Circulating Tumor Cells Shed Shearosome Extracellular Vesicles in Capillary Bifurcations That Activate Endothelial and Immune Cells

Advanced Science, EarlyView.
Using microfluidic models of capillary networks, this study discovered that fluid shear stresses on circulating tumor cells transiting through capillary‐sized bifurcations shed a novel class of shear‐dependent large extracellular vesicle, “shearosomes”, whose proteome comprises of over 3000 distinct proteins.

Protector Control PC-AODV-BH in The Ad Hoc Networks

, 2016
In this paper we deal with the protector control that which we used to secure AODV routing protocol in Ad Hoc networks. The considered system can be vulnerable to several attacks because of mobility and absence of infrastructure. While the disturbance is
