The controllable intramolecular amidoarylation and hydroarylation of alkynes has been achieved via rhodium(III)-catalyzed C-H activation. merger two distinct reaction pathways allows for the development atom- step-economic protocols switchable synthesis 3,4-fused indoles chromans, respectively.
Abstract An all-carbon memristive synapse is highly desirable for hardware implementation in future wearable neuromorphic computing systems. Graphene oxide (GO) can exhibit resistive switching (RS) and may be a feasible candidate to achieve this objective. However, the digital-type RS often occurring GO-based memristors restricts biorealistic emulation of synaptic functions. Here, an with analog-type behavior was demonstrated through photoreduction GO N-doped carbon quantum dot (NCQD)...
Polyoxometalate (POM)-based metal–organic frameworks (MOFs) with nanostructure represent a class of promising heterogeneous nanocatalysts. As yet, direct one-step controllable synthesis pure nanoscale POM-MOFs catalysts is an extremely huge challenge owing to highly complicated synthetic conditions. Herein, for the first time, we fabricated ultrathin (∼5 nm) mixed-valence {V16} clusters-incorporated framework nanosheets [Ni(4,4′-bpy)2]2 [V7IVV9VO38Cl]·(4,4′-bpy)·6H2O (NENU-MV-1a) via...
An efficient solvent-dependent regioselective [3 + 2]-cycloaddition/iodocyclization cascade reaction of alkyne-tethered chalcones/cinnamates and TosMIC has been developed. The represents a novel protocol for the expedient divergent one-pot synthesis benz[e]indoles spiro[indene-1,3′-pyrroles] from acyclic common precursors at room temperature.
Perfluorooctane sulfonate (PFOS) was listed as a persistent organic pollutant by the Stockholm Convention. As typical alternative to PFOS, sodium p -perfluorous nonenoxybenzene (OBS) has recently been detected in aquatic environment which caused great concern. For first time, adsorption behaviour and mechanism of OBS on activated carbon (AC) with different physical chemical properties were investigated. Decreasing particle size AC can accelerate its for OBS, while too small not conducive...
Multidimensional item response theory (MIRT) is widely used in assessment and evaluation of educational psychological tests. It models the individual patterns by specifying a functional relationship between individuals' multiple latent traits their responses to test items. One major challenge parameter estimation MIRT that likelihood involves intractable multidimensional integrals due variable structure. Various methods have been proposed involve either direct numerical approximations or...

A photo-tunable and flexible organic RRAM device based on poly(4-vinylphenol) (PVP) N-doped carbon quantum dot nanocomposites for encrypted image storage.
Soybean mosaic virus (SMV) is the most prevalent soybean viral disease in world. As a critical enzyme secondary metabolism of plants, especially lignin synthesis, cinnamyl alcohol dehydrogenase (CAD) widely involved plant growth and development, defense against pathogen infestation. Here, we performed RNAseq-based transcriptome analyses highly SMV-resistant accession (BYO-15) wild (Glycine soja) SMV-susceptible cultivar (Williams 82), also sequenced together with resistant susceptible their...
We developed an intensity-modulated light-emitting device (LED) by integrating a p-GaN/n-ZnO heterojunction with multilevel resistive random access memory (RRAM). In this device, the luminous intensity of LED can be adjusted through regulating injection current according to variable resistance state RRAM. As one critical foundation fabrication, uniform operation RRAM was achieved inserting carbon quantum dots into HfO2−x as local-electric-field regulator. Eventually, reversible regulation...
Background China is one of the top countries with most significant number or proportion retracted publications, which has garnered attention. Methods Using Retraction Watch Database, we collected articles written by Chinese authors from 31 provinces in mainland China, spanning period between January 1, 2012, and December 31, 2023. We used Geographical Information Science to analyze spatial distribution characteristics identify high-risk clusters areas. Results A total 14,445 authored...

Teachers play an important role in the educational system. Teacher self-efficacy, job satisfaction, school climate, and workplace well-being stress are four individual characteristics shown to be associated with tendency turnover. In this article, data from Teaching Learning International Survey (TALIS) 2018 teacher questionnaire analyzed, goal understand interplay amongst these characteristics. The main purposes of study (1) measure extreme response style for each scale using unidimensional...
Model-data fit plays an important role in any statistical analysis, and the primary goal is to detect preferred model based on certain criteria. Under cognitive diagnostic assessment (CDA) framework, a family of sequential models introduced handle polytomously scored data, which are attained by answering constructed-response items sequentially. The presence attribute hierarchies, can provide useful information about nature attributes, will help understand relation between attributes response...
Ordinary differential equations (ODEs) are important mathematical models in applied sciences to describe dynamic processes. The parameters involved the usually have specific meanings, and hence need be estimated from observed data. In applications, may change with time, which called time-varying parameters. this paper, we propose a Bayesian penalized B-spline method estimate initial values ODEs. Simulation studies show that is more efficient than two-stage local polynomial method....
Item response models often cannot calculate true individual probabilities because of the existence disturbances (such as guessing and cheating). Many studies on aberrant responses under item theory (IRT) framework had been conducted. Some them focused how to reduce effect responses, others detect examinees, such person fit analysis. The purpose this research was derive a generalized formula bias with/without that showed both non-aberrant data capability estimation mathematically. A new...
We study the dynamical Casimir-Polder force on a two-level atom with different initial states in one-dimensional dielectric cavity output coupling, and obtain analytical expression of expectation value force. Results show that values may be affected by atom. Moreover, vanish at some special atomic positions properly selecting state system. The effects relative constants size are also discussed.
The insect Uvarovites inflatus Uvarov is highly appreciated in China. It known for its distinctive songs and horn-like forewings raised commercially lovers. U. was previously categorized as part of the monotypic genus Uvarovites; however, there little molecular evidence to support this taxonomic classification. This study obtained investigated mitogenome inflatus, were characterized compared with other Ensifera species whose mitogenomes are available. By performing mitochondrial analysis, we...
