Time division duplex (TDD) systems and their crossed-slot interference problem in cellular environment have been attracting increasing interest. To mitigate the crossed-slot interference, we propose the REgion-based Decentralized Time Slot Allocation (RED-TSA) strategy, and evaluate its call blocking probability, uplink SINR, and overall uplink throughput compared with those of previous TSA str...

Histone deacetylase inhibitors and proteasome inhibitor are all emerging as new classes of anticancer agents. We chose TSA and PS-341 to identify whether they have a synergistic efficacy on human ovarian cancer cells. After incubated with 500 nM TSA or/and 40 nM PS-341, we found that combined groups resulted in a striking increase of apoptosis and G2/M blocking rates, no matter in A2780, cispla...

We compared the sensitivity and specificity of the Strep A Optical ImmunoAssay (OIA) method with our routine trypticase soy agar with 5% sheep blood (TSA) culture technique and with a broth-enhanced culture in the diagnosis of group A beta-hemolytic streptococcal infection. Compared with broth-enhanced culture, the Strep A OIA had a sensitivity and specificity of 94.8% and 98.8%, respectively; ...

Research objective: establish the impact of Left Atrium Volume Index (LAVI) on effectiveness Thoracoscopic Ablation (TSA) in Treatment Atrial Fibrillation (AF) and define risk factors for manifestation supraventricular arrhythmias long-term follow-up results Methods. Prospective cohort study 121 patients with AF (from 2018 to 2021) who performed TSA. The were divided into two groups: increased ...

The use of microbolometers for Thermoelastic Stress Analysis (TSA) has the potential substantially reducing deployment costs, as well providing more compact and lightweight solutions in comparison to costly, bulky less rugged photon detector based infrared cameras. However, microbolometer performance terms response time sensitivity is than what can be achieved with detectors. As TSA becoming wi...

Background:  The aberrant and altered patterns of gene expression play an important role in the biology of cancer and tumorigenesis. DNA methylation and histone deacetylation are the most studied epigenetic mechanisms. Histone deacetylase inhibitors (HDACIs) such as valproic acid (VPA) and trichostatin A (TSA) are a group of anticancer compounds for the treatment of solid and hematological canc...

Histone deacetylase (HDAC) inhibitors are being developed as new clinical agents in cancer therapy, in part because they interrupt cell cycle progression in transformed cell lines. To examine cell cycle arrest induced by HDAC inhibitor trichostatin A (TSA), a cytoblot cell-based screen was used to identify small molecule suppressors of this process. TSA suppressors (ITSAs) counteract TSA-induce...

The ubiquitin‑specific protease 22 (USP22) gene is overexpressed in the majority of types of cancer cells, and has been implicated in tumorigenesis. However, the mechanisms that regulate its expression remain unclear. The results of the present study demonstrated that the expression of USP22 is negatively regulated by trichostatin A (TSA), a classical histone deacetylase inhibitor. Furthermore,...

The Two-Stage Algorithm (TSA) has been extensively used and adapted for the identi cation of Hammerstein systems. It essentially deals with the parameter estimation problem for a linear regression parameterized in a bilinear form. This paper is motivated by a somewhat contradictory fact: though the optimality of the TSA has been established only in the case of some special weighting matrices, t...

Twitter has become a major social media platform and attracted considerable interest among researchers in sentiment analysis. Research into Sentiment Analysis (TSA) is an active subfield of text mining. TSA refers to the use computers process subjective nature data, including its opinions sentiments. In this research, thorough review most recent developments area, wide range newly proposed algo...
