Electrochemical properties of redox proteins, which can cause the reversible changes in resistance according to their reactions solution, are fundamental and practical importance bioelectrochemical applications. These often depend on chemical activity transition metal ions as cofactors within active sites proteins. Here, we demonstrate for first time that dried protein films based ferritin nanoparticles be caused by externally applied voltage a result charge trap/release Fe(III)/Fe(II)...
DNA methylation is an epigenetic modification of in which methyl groups are added at the 5-carbon position cytosine. Aberrant methylation, has been associated with carcinogenesis, can be assessed various biological fluids and potentially used as markers for detection cancer. Analytically sensitive specific assays targeting low-abundance fragmented needed optimal clinical diagnosis prognosis. We present a nanopore-based direct assay that circumvents bisulfite conversion polymerase chain...
A robust method for preparing nanocomposite multilayers was developed to facilitate the assembly of well-defined hydrophobic nanoparticles (i.e., metal and transition oxide NPs) with a wide range functionalities. The resulting were stable in both organic aqueous media characterized by high NP packing density. For example, inorganic NPs (including Ag, Au, Pd, Fe₃O₄, MnO₂) dispersed [corrected]were shown undergo layer-by-layer amine-functionalized polymers form while incurring minimal physical...
Abstract In addition to the choice of visual encodings, effectiveness a data visualization may vary with analytical task being performed and distribution values. To better assess these effects create refined rankings we conduct an experiment measuring subject performance across types (e.g., comparing individual versus aggregate values) distributions varied cardinalities entropies). We compare 12 encoding specifications trivariate involving 1 categorical 2 quantitative fields, including use...
We demonstrate the successful preparation of multifunctional silica colloids by coating with 2-bromo-2-methylpropionic acid (BMPA)-stabilized quantum dots (BMPA-QDs) and BMPA-stabilized iron oxide particles (BMPA-Fe(3)O(4)), along amine-functionalized poly(amidoamine) (PAMA) dendrimers, using layer-by-layer (LbL) assembly based on a nucleophilic substitution (NS) reaction between bromo amine groups in organic media. The QDs Fe(3)O(4) nanoparticles used this study were directly synthesized...
Animated transitions help viewers follow changes between related visualizations. Specifying effective animations demands significant effort: authors must select the elements and properties to animate, provide transition parameters, coordinate timing of stages. To facilitate this process, we present Gemini, a declarative grammar recommendation system for animated single-view statistical graphics. Gemini specifications define "steps" in terms high-level visual components (marks, axes, legends)...
Perovskite nanoparticle‐based nanocomposite thin films strictly tailored using unconventional layer‐by‐layer (LbL) assembly in organic media for piezoelectric nanogenerators (NGs) are demonstrated. By employing sub‐20‐nm BaTiO 3 nanoparticles stabilized by oleic acid ligands (i.e., OA‐BTO NPs ) and carboxylic (COOH)‐functionalized polymers, such as poly(acrylic acid) (PAA), the resulting NP /PAA multilayers prepared exploiting high affinity between COOH groups of PAA BTO . The ferroelectric...
Data augmentation has been actively studied for robust neural networks. Most of the recent data methods focus on augmenting datasets during training phase. At testing phase, simple transformations are still widely used test-time augmentation. This paper proposes a novel instance-level that efficiently selects suitable test input. Our proposed method involves an auxiliary module to predict loss each possible transformation given Then, having lower predicted losses applied The network obtains...
We propose a multi-viewer tracking integral imaging system for viewing angle and zone improvement. In the system, pickup angles in each elemental lens array are decided by positions of viewers, which means image can be made viewer to provide wider larger zone. Our is implemented with an infrared camera light emitting diodes track viewers' exact robustly. For multiple viewers watch integrated three-dimensional images it needed formulate relationship between images. analyzed conditions...

Determining tumor microsatellite status has significant clinical value because tumors that are instability-high (MSI-H) or mismatch repair deficient (dMMR) respond well to immune checkpoint inhibitors (ICIs) and oftentimes not chemotherapeutics.

We present an adaptively accelerated Lucy-Richardson (AALR) method for the restoration of image from its blurred and noisy version. The conventional (LR) is nonlinear therefore convergence very slow. a novel to accelerate existing LR by using exponent on correction ratio LR. This computed in each iteration, first-order derivatives deblurred previous two iterations. Upon this exponent, AALR improves speed at first stages ensures stability later iteration. An expression estimation acceleration...
A new analogue circuit design methodology using independently optimised self‐cascode (SC) structures is proposed. Based on the concept of dual‐workfunction‐gate structures, which are equivalent to SC transconductance and output resistance MOSFETs were used in differential input stages, respectively. An operational amplifier (opamp) with proposed standard 0.18 µm CMOS technology was designed provide better performance. The measured DC gain fabricated opamp independently‐optimised...

In this paper, we present a fast object detection algorithm based on color histograms and local binary patterns (LBP). The proposed method consists of two steps: coarse target precise detection. During the step, small number candidates were generated using integral histogram matching. To reduce computational complexity, only used dominant was determined by comparing LBP feature distributions with those candidates. Experimental results show that is efficient robust.
