Light-intensity selective superlinear photodetectors with ultralow dark current can provide an essential breakthrough for the development of high-performing near-sensor vision processing. However, processing is not only conceptually important device operation (given that sensors naturally exhibit linear/sublinear responses), but also to get rid massive amount data generated during object sensing and classification noisy inputs. Therefore, achieving giant photoresponse while maintaining...
Cerebral ischemia-reperfusion injury (CI/RI) remains the main cause of disability and death in stroke patients due to lack effective therapeutic strategies. One issues related CI/RI treatment is presence blood-brain barrier (BBB), which affects intracerebral delivery drugs. Ginkgolide B (GB), a major bioactive component commercially available products Ginkgo biloba, has been shown significance by regulating inflammatory pathways, oxidative damage, metabolic disturbance, seems be candidate...
Organic thermoelectric (TE) attracts considerable interest as a next-generation energy conversion technology; however, its practical application is still restricted by low power factors. Herein, we report generally applicable solvent-combination doping method for improving TE properties of conjugated polymers (CPs). Residual solvents in ternary solvent enlarged the free volume CP films. This beneficial effect boosted both dopant diffusion efficiency and charge carrier density doped films,...
Obstructive sleep apnea is a highly prevalent cyclic repetitive hypoxia-normoxia respiratory disorder characterized by intermittent upper-airway collapse. It mainly diagnosed using in-laboratory polysomnography. However, the time-spatial constraints of this procedure limit its application. To overcome these limitations, there have been studies aiming to develop clinical prediction formulas for screening obstructive risk factors disorder. applicability formula restricted group specific...
Ferrocene-based nanoparticles have garnered interest as reactive oxygen species (ROS)-responsive nanocarriers of anticancer drugs and imaging agents. However, their biomedical applications remain limited due to poor physiological stability. PEGylation improves stability biocompatibility. In this study, we aimed develop novel PEG-ferrocene (PFNPs) with enhanced ROS responsiveness for the delivery paclitaxel (PTX) improved ferrocene nanoparticles, inhibiting ROS-responsive destruction. Several...
In this paper, we categorize STT-MTJ based non-volatile flip-flops (NV-FF) into two basic structures: merged latch and sensing circuit (MLS) structure separated (SLS) structure. We also analyze the structures with various types of write circuits. HSPICE simulation results using industry-compatible 45-nm model parameter shows SLS has better performance according to D-Q delay, PDP, current than MLS because can optimize FF operation independently. Among circuit, cross coupled inverter including...
Resistive nonvolatile memory (NVM) devices such as spin transfer torque random access (STT-RAM) and resistive are considered to be leading candidates for next-generation devices. With technology scaling, the sensing margin (SM) of NVM is significantly degraded because increased process variation decreased read current. In this brief, we propose an offset-canceling dual-stage circuit (OCDS-SC) that has two major advantages offset voltage cancelation double SM. Monte Carlo HSPICE simulation...
Porous carbon electrodes that accumulate charges at the electrode/electrolyte interface have been extensively investigated for use as electrochemical capacitor (EC) because of their great attributes driving high-performance energy storage. Here, we report porous nanofibers (p-CNFs) EC made by formation a composite monodisperse silica nanoparticles and polyacrylonitrile (PAN), oxidation/carbonization composite, then etching. The pore features are controlled changing weight ratio PAN to...
Bioactive compounds are widely used in the bio-industry because of their antioxidant and antibacterial activities. Because excessive oxidative stress, which causes various diseases humans, preservatives bioproducts cause allergies contact dermatitis, it is important to use natural bioactive minimize stress. α-bisabolol (ABS) a compound with both properties. However, its water-insolubility makes utilization difficult. In this study, ABS-loaded polyglyceryl-4 caprate nanoparticles (ABS@NPs)...
The use of herbal medicine has increased tremendously over the last decades, generating a considerable amount waste.

When using Pt/AC in at 500 °C, generation benzyl species was suppressed. This likely...
We aimed to evaluate the survival benefits of coadministering statins and multityrosine kinase inhibitors (TKIs) in patients with advanced hepatocellular carcinoma (HCC). Data from Health Insurance Review Assessment Service Korea (2010–2020) were utilized. Statin use (≥28 cumulative defined daily doses) was analyzed, 1534 statin users matched 6136 non-users (1:4 ratio) using propensity scores. Primary secondary outcomes overall (OS) progression-free (PFS). significantly improved OS (hazard...

The three-dimensional ordered structure (M-CNT@CF) provides porosity and bicontinuous paths for charge transport, resulting in high energy considerable rate retention capability as compared nonstructured CF CNT-coated electrodes. A micro-supercapacitor (f-MSC) composed twisted pair solid polymer electrolyte shows...
Research on phase-change random access memory (PRAM) for multilevel cells (MLCs) has been actively conducted owing to the advantages of PRAM cells, such as large resistance margin and fast read/write time. However, drift (R-drift), which increases with time, should be overcome achieve MLC operation.

Antimony oxide (ATO) is used mainly as a flame retardant, but it classified hazardous substance. Therefore, regulations on the use of antimony trioxide (ATO(3)) and pentoxide (ATO(5)) in textile products are being developed. Accordingly, there need for alternative retardants. In this study, tetroxide (ATO(4)), which has higher thermal stability resistance to acids alkalis than ATO(3) or ATO(5), was selected assess its an retardant. First, ATO(4) were added poly(acrylonitrile-co-vinylidene...
As the technology node scales down, spin-transfer-torque random access memory (STT-RAM) has been considered as a promising solution owing to its scalability. However, increased process variation and reduced supply voltage lead degradation in sensing yield (SY) well an increase read disturbance probability. Temperature further aggravates this phenomenon.
