Human voice recognition via skin-attachable devices has significant potential for gathering important physiological information from acoustic data without background noise interference. In this study, a highly sensitive and conductive wearable crack-based strain sensor was developed voice-recognition systems. The fabricated using double-layer structure of Ag nanoparticles (NPs) metal on biocompatible polydimethylsiloxane substrate. top layer acts as conducting active layer, whereas the...
In this study, we demonstrate significant advancements in hafnium oxide-based ferroelectric field-effect transistors (FeFET) by integrating two engineering methods: laminated (FE) thin films and CF4-based plasma treatment. Individually, these techniques exhibit specific trade-offs; however, their combined application effectively mitigates drawbacks, maximizing synergistic benefits. Compared to the pristine FeFET, our results an improvement endurance more than one order of magnitude, while...
This study demonstrates the use of a top-gate ferroelectric field effect transistor (FeFET) with replacement electrode solid phase epitaxy (SPE) method and high deposition temperature during atomic layer (ALD)....
Deubiquitinating enzymes (DUBs) are crucially involved in controlling signal transductions, and reverse ubiquitination by removing the ubiquitin from protein substrates. The Hippo signaling has an important role tissue growth, cell proliferation, differentiation, apoptosis. Since disruption of is associated with a number diseases, it imperative to investigate molecular mechanism signaling.DUB screening was performed using kidney mouse unilateral ureteric obstruction (UUO) model identify...
The ubiquitin-proteasome system (UPS) is responsible for proteasomal degradation, regulating the half-life of protein. Deubiquitinating enzymes (DUBs) are components UPS and inhibit degradation by removing ubiquitins from protein substrates. Herpesvirus-associated ubiquitin-specific protease (HAUSP) one such deubiquitinating enzyme has been closely associated with tumor development. In a previous study, we isolated putative HAUSP binding substrates two-dimensional electrophoresis (2-DE)...

Abstract The demand for self‐powered photodetectors (PDs) capable of NIR detection without external power is growing with the advancement technologies such as LIDAR and object recognition. Lead sulfide quantum dot‐based (PbS QPDs) excel in detection; however, their operation hindered by carrier traps induced surface defects unfavorable band alignment zinc oxide nanoparticle (ZnO NP) electron‐transport layer (ETL). In this study, an effective azide‐ion (N 3 − ) treatment introduced on a ZnO...
HASPIN has been identified as a nuclear Ser/Thr kinase specifically expressed in haploid germ cells. inhibitors were recently isolated, and their antitumor activity reported. Colorectal cancer occurs with high incidence worldwide. In this study, we examined whether inhibitor CHR-6494 suppresses progression Apc mice, familial colon tumor disease model. Mice treated by intraperitoneal injection of for 50 days. Following the treatment period, intestinal polyps counted testosterone...
Abstract Silver (Ag) metal‐based structures are promising building blocks for next‐generation photonics and electronics owing to their unique characteristics, such as high reflectivity, surface plasmonic resonance effects, electrical conductivity, tunable electron transport mechanisms. However, Ag exhibit poor sustainability in terms of device performance because harsh chemicals, particularly S 2− ions present the air, can damage structures, lowering optical properties. Here, chemistry with...
2050 탄소중립 실현을 위한 에너지 전환시대에 접어들면서 광물 확보의 중요성이 그 이전 시대와 비교하여 높아지고 있으며, 특히 공급 리스크가 존재하는 ‘핵심광물’에 대한 전세계 각국의 관심이 최근 들어 고조되고 있다. 주요국들은 선제적으로 새로이 핵심광물 목록을 발표하거나 기존 목록의 갱신에 나서고 있는데, 중에서도 배터리 분야와 관련된 리튬, 니켈, 코발트, 흑연 등의 광물이 공통적으로 선정된 것으로 나타난다. 이들 핵심광물의 수요는 2020년 대비 2040년 최소 3배에서 42 배까지 증가할 예상되고 이는 친환경 전기차 및 저장 시스템 분야에서의 수요 확대에 주로 기인할 보인다. 배터리용 4종의 광산 생산지는 종류에 따라 상이하게 나타나나 상품성 금속 또는 재료의 생산이 대체로 중국에서 이루어지고 있고, 현재 급격 한 증가에 가격이 급상승하고 있어 위기성이 높은 상황이다. 이에 본 연구에서는 생산 현황, 시장 기술 동향에 대해 분석하고 이로부터 국내 확보에 시사점을 제시하였다.
We report a facile and effective way to prepare cell labelling quantum dots (QDs) using cetyltrimethylammonium bromide (CTAB) enhance biocompatibility of the QD labels. There are several reports on use this ligand encapsulate nanoparticles including QDs. However, due its high cellular toxicity, CTAB has still not been employed QDs for labelling. After removing free by dialysis, we could successfully CdSe/CdS/ZnS (core/shell/shell) In addition, found that simple introduction sonication step...
Premature ovarian failure (POF) is defined as loss of function in women less than 40 years age. The causes POF are diverse and include environmental factors. Di-2-ethylhexyl phthalate (DEHP) one factor that may cause POF. ubiquitin-proteasome system maintains intracellular balance by promoting or inhibiting protein degradation.

Log-Structured Merge (LSM) tree-based Key-Value Stores (KVSs) are widely adopted for their high performance in write-intensive environments, but they often face degradation due to write stalls during compaction. Prior solutions, such as regulating I/O traffic or using multiple compaction threads, can cause unexpected drops throughput increase host CPU usage, while hardware-based approaches FPGA, GPU, and DPU aimed at reducing duration introduce additional hardware costs. In this study, we...
