The authors investigated the data retention properties of NiOy resistors exposed to sputtered particles and found that they depended on bias polarity used program data. Only in high resistance state programmed by applying positive top electrode were easily damaged. This suggests “reset” process can take place when anodic side conductive filaments, which formed during “forming” process, is insulated. In addition, test for thermal stress reset thermally.
Abstract Highly efficient tissue repair is pivotal for surviving damage-associated stress. Plants generate callus upon injury to heal wound sites, yet regulatory mechanisms of remain elusive. Here, we identified WUSCHEL-RELATED HOMEOBOX 13 (WOX13) as a key regulator formation and organ adhesion in Arabidopsis (Arabidopsis thaliana). WOX13 belongs an ancient subclade the WOX family, previous study shows that orthologs moss Physcomitrium patens (PpWOX13L) are involved cellular reprogramming at...
A hypothesis based on the model that explains resistance change effect of resistive random access memory by redox reaction is proposed. This leads to conclusion relationship between polarity applied bias voltage and resultant in p-type semiconductors opposite for n-type semiconductors. The dependence ZnO Ga-doped (GZO), which are semiconductors, NiO, a semiconductor, were investigated using conducting atomic force microscopy. Opposite was confirmed induce GZO NiO into same state, consistent...
This study focused on the detection of plasmid-mediated mcr colistin resistance gene in Escherichia coli isolates from wastewater treatment plants (WWTPs). Seven influent samples were collected three WWTPs Nagano Prefecture, Japan, during August and December 2018. Colistin-resistant E. selected colistin-supplemented CHROMagar ECC plates. mcr-1-positive subjected to whole-genome sequencing (WGS) analysis. From six samples, seven but extended-spectrum β-lactamase (ESBL)-negative belonging...
Convolutional neural network is valid for object segmentation. In recent years, it has been applied to the fields of medicine and cell biology. Each class a different number pixels in an image. Therefore, accuracy semantic segmentation varies drastically between objects with large small pixels. this paper, we propose X-Net that integrates two encoders decoders solve problem. This advantage extracting rich features from using complement location information objects. By loss functions each...
Plants have the regenerative ability to reconnect cut organs, which is physiologically important survive severe tissue damage. The organs utilized as grafting combine two different individuals. Callus formation at graft junction facilitates organ attachment and vascular reconnection. While it well documented that local wounding signals provoke callus formation, how differentially regulated each end remains elusive. Here, we report activity asymmetrical between top bottom ends by differential...
All-inorganic cesium lead halide perovskite quantum dots (QDs) have several potential applications, owing to their unique optical and electronic properties. However, patterning QDs using conventional methods is difficult because of the ionic nature QDs. Here, we demonstrate a approach, in which are patterned polymer films through photocuring monomers under light illumination. The pattern illumination creates transient concentration difference, drives form patterns; hence controlling...
Large variation in basic memory properties is a serious issue that hinders the practical use of ReRAMs. This study revealed one main factors causing presence multiple filaments each cell. An operating filament switches to another having smallest set voltage at instant switching. We propose resistive switching model takes into consideration. A Monte Carlo simulation based on reproduces Vset distribution. The dependence <Vset> number cycles was predicted by and confirmed experimentally.

The development of methods to pattern nanocrystals with different sizes and shapes remains a challenge. In this study, we demonstrate unique class bottom-up approaches assemble into patterns. Our approach for patterning focuses on the utilization control chemical reaction solvents surrounding nanocrystals. photopolymerization solvent molecules through photomask creates time-dependent concentration gradients solvents. Dispersed such as silver nanowires (AgNWs) migrate are gradually organized...
Two hypotheses were formulated to validate a multi-filament model (MFM) as mechanism for the cycle-to-cycle dispersion of Vset in resistive random-access memory. The first is that probability Δ(1/Vset) > 0, P[Δ(1/Vset) 0], increases with number filaments one memory cell, Nfila, and decreases increasing switching cycle, n. Here, difference between inverse set voltages after n-th (n + 1)-th reset processes [1/Vset(n) − 1/Vset(n 1)]. Thus, Nfila second hypothesis Δ(1/R) P[Δ(1/R) agrees...

Flexible transparent resistive random access memory (FTReRAM) can be fabricated by sandwiching a wide band gap oxide such as ZnO between electrodes tin-doped indium (ITO) on polymer flexible sheets. However, an alternative conducting (TCO) to ITO is desired because of the high cost and scarcity element. Although one best candidates Ga doped (GZO), low glass transition temperature substrates prevents fabrication GZO films with resistivity ρ. Moreover, bombardment energetic oxygen position...

Abstract Perovskite quantum dots (PQDs) are inherently unstable under environmental conditions, making it difficult to form patterns using conventional techniques. Herein, a unique approach is reported for patterning PQDs by the nonuniform photopolymerization of liquid monomer. The demonstrated employs PQD‐dispersed photocurable liquid, which illuminated with patterned light formed digital micromirror device (DMD). As monomers photopolymerized, in solution diffusion (migration), and...
