Bifunctional Device with High‐Energy Storage Density and Ultralow Current Analog Resistive Switching
Authors: Liu Qian , Xue Qiang , Wang Yanbin , Wei Xianhua , Hao Jianhua 
Published: January 2021

AbstractA bifunctional device capable of simultaneously achieving dielectric energy storage and resistive switching is first designed and fabricated based on a conventional metal–insulator–metal (MIM) structure. Typically, Al/TaOx/Pt structure shows a high breakdown strength up to 5.07 MV cm−1 and a relatively high‐energy density of 27.6 J cm−3. Meanwhile, the leakage current of the MIM structure is at the sub‐nanoampere level and exhibits the typical characteristic of analog switching under an applied voltage of about 12 volts. The energy density and the switching current in the developed integrated MIM structure are comparable to the corresponding performances in discrete binary oxides capacitors with linear dielectric and oxide‐based memristors, respectively. Furthermore, synaptic functions with short‐term and long‐term plasticities can be realized. Both of the device properties are found to be correlated to the role of the AlOx interfacial layer between the Al electrode and the dielectric layer, which provides the possibility of coupling between these two functions coexisting in the MIM structure. The prototypical bifunctional device offers a great prospect for multifunctional energy and neuromorphic applications.

Published: January 2021

AbstractThin‐film transistor circuits on flexible substrates hold major promise for next‐generation human–machine interface systems. However, a major bottleneck is the reliability of the interconnect, which is prone to open‐circuit faults due to mechanical, electrical, and environmental stresses. Here, self‐healing interconnects in thin‐film transistor circuits are demonstrated on flexible substrates resulting in the restoration of >99% of the prefault current. The active material for self‐healing is a dispersion of conductive particles in an insulating fluid that is contained over the interconnect. Healing is triggered by the electric field that appears in the open gap during the occurrence of the fault. The engineering of the active material is discussed; self‐healing circuits are demonstrated and analyzed; and methods to package and integrate the self‐healing feature are discussed with the process flow. This work sets a new benchmark for reliable inkjet‐printed thin‐film transistor circuits on flexible substrates.

AbstractTo develop effective electrocatalytic splitting of acidic water, which is a key reaction for renewable energy conversion, the fundamental understanding of sluggish/destructive mechanism of the oxygen evolution reaction (OER) is essential. Through investigating atom/proton/electron transfers in the OER, the distinctive acid–base (AB) and direct‐coupling (DC) lattice oxygen mechanisms (LOMs) and adsorbates evolution mechanism (AEM) are elucidated, depending on the surface‐defect engineering condition. The designed catalysts are composed of a compressed metallic Ru‐core and oxidized Ru‐shell with Ni single atoms (SAs). The catalyst synthesized with hot acid treatment selectively follows AB‐LOM, exhibiting simultaneously enhanced activity and stability. It produces a current density of 10/100 mA cm−2 at a low overpotential of 184/229 mV and sustains water oxidation at a high current density of up to 20 mA cm−2 over ≈200 h in strongly acidic media.

AbstractAimThis study investigated whether preoperative serum transferrin, a rapid‐turnover protein, was associated with prognosis after colorectal cancer (CRC) resection.MethodsWe evaluated preoperative transferrin, which was calculated as iron and unsaturated iron‐binding capacity, in 501 patients who underwent surgery for Stage I–III CRC. Transferrin level was directly proportional to total iron‐binding capacity (TIBC), and TIBC < 250 μg/dl was defined as low transferrin. The associations between transferrin and prognosis were evaluated in univariate and multivariate Cox proportional hazards analyses.ResultsFifty‐eight of 501 patients (11.5%) had low transferrin. In these patients, low transferrin was significantly associated with high age, female gender, low body mass index (<18.5), high white blood cell count, low total protein, low albumin, high C‐reactive protein, low hemoglobin, and low neutrophil/lymphocyte ratio. In the univariate analysis, low transferrin was associated with shorter relapse‐free survival (RFS) (hazard ratio [HR] 2.180, 95% confidence interval [CI] 1.417‐3.354, P < .001), overall survival (OS) (HR 2.930, 95% CI 1.784‐4.811, P < .001), and cancer‐specific survival (CSS) (HR 2.122, 95% CI 1.053‐4.275, P = .035). In multivariate analysis, high age (P < .001), Glasgow Prognostic Score (P = .009), and low transferrin (HR 2.336, 95% CI 1.173‐4.654, P = .011) were independently associated with shorter OS, and depth of invasion pT4 (P = .015), presence of lymph node metastasis (P = .001), low hemoglobin (P = .034), and low transferrin (HR 2.638, 95% CI 1.113‐5.043, P = .025) were independently associated with shorter CSS.ConclusionsPreoperative serum transferrin in Stage I–III CRC patients was identified as a novel prognostic marker by univariate and multivariate analyses.

Published: January 2021

AbstractThe chemoselective C−H functionalization of unprotected N‐heterocycles is a challenging task in organic synthesis. Herein, we report on a Brønsted‐acid catalyzed reaction of aryl/aryl diazoalkanes with unprotected N‐heterocycles to selectively allow for C−H functionalization at the C3‐position under mild reaction conditions and short reaction time without the need of protecting groups. The general applicability of this method was further expanded towards protected indole and unprotected pyrrole heterocycles.
Neuromechanical linkage between the head and forearm during running

Published: January 2021

AbstractObjectivesThe main objective was to test the hypothesis of a neuromechanical link in humans between the head and forearm during running mediated by the biceps brachii and superior trapezius muscles. We hypothesized that this linkage helps stabilize the head and combats rapid forward pitching during running which may interfere with gaze stability.Materials and methodsThirteen human participants walked and ran on a treadmill while motion capture recorded body segment kinematics and electromyographic sensors recorded muscle activation. To test perturbations to the linkage system we compared participants running normally as well as with added mass to the face and the hand.ResultsThe results confirm the presence of a neuromechanical linkage between the head and forearm mediated by the biceps and superior trapezius during running but not during walking. In running, the biceps and superior trapezius activations were temporally linked during the stride cycle, and adding mass to either the head or hand increased activation in both muscles, consistent with our hypothesis. During walking the forces acting on the body segments and muscle activation levels were much smaller than during running, indicating no need for a linkage to keep the head and gaze stable.DiscussionThe results suggest that the evolution of long distance running in early Homo may have favored selection for reduced rotational inertia of both the head and forearm through synergistic muscle activation, contributing to the transition from australopith head and forelimb morphology to the more human‐like form of Homo erectus. Selective pressures from the evolution of bipedal walking were likely much smaller, but may explain in part the intermediate form of the australopith scapula between that of extant apes and humans.

AbstractIntroductionThis study investigated the diagnostic and disease‐monitoring potential of plasma biomarkers in mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia and cognitively unimpaired (CU) individuals.MethodsPlasma was analyzed using Simoa assays from 99 CU, 107 MCI, and 103 AD dementia participants.ResultsPhosphorylated‐tau181 (P‐tau181), neurofilament light, amyloid‐β (Aβ42/40), Total‐tau and Glial fibrillary acidic protein were altered in AD dementia but P‐tau181 significantly outperformed all biomarkers in differentiating AD dementia from CU (area under the curve [AUC] = 0.91). P‐tau181 was increased in MCI converters compared to non‐converters. Higher P‐tau181 was associated with steeper cognitive decline and gray matter loss in temporal regions. Longitudinal change of P‐tau181 was strongly associated with gray matter loss in the full sample and with Aβ measures in CU individuals.DiscussionP‐tau181 detected AD at MCI and dementia stages and was strongly associated with cognitive decline and gray matter loss. These findings highlight the potential value of plasma P‐tau181 as a non‐invasive and cost‐effective diagnostic and prognostic biomarker in AD.
Enhancement of the Quantum Coherence of the Rydberg Atoms System by Weak Measurement
Authors: Chen Qi , Xu Jing‐Bo 
Published: January 2021

AbstractThe influence of weak measurement along with quantum measurement reversal on the Rydberg atoms system is investigated, and is found to have an important practical significance as both weak measurement along with quantum measurement reversal and Rydberg atoms system can be experimentally realized. The quantum coherence and the entropic uncertainty relation of the system are explored, and it is found that the quantum coherence of the system is enhanced and the values of uncertainty and the uncertainty bound are reduced under some particular weak measurements along with quantum measurement reversals. This indicates that the decoherence effect of the system can be weakened by weak measurement along with quantum measurement reversal. Furthermore, the trace distance which is a reflection of the entanglement is also examined, and it is shown that weak measurement along with quantum measurement reversal can improve the entanglement of the system.

AbstractPyrazine‐linked hybrid ultramicroporous (pore size <7 Å) materials (HUMs) offer benchmark performance for trace carbon capture thanks to strong selectivity for CO2 over small gas molecules, including light hydrocarbons. That the prototypal pyrazine‐linked HUMs are amenable to crystal engineering has enabled second generation HUMs to supersede the performance of the parent HUM, SIFSIX‐3‐Zn, mainly through substitution of the metal and/or the inorganic pillar. Herein, we report that two isostructural aminopyrazine‐linked HUMs, MFSIX‐17‐Ni (17=aminopyrazine; M=Si, Ti), which we had anticipated would offer even stronger affinity for CO2 than their pyrazine analogs, unexpectedly exhibit reduced CO2 affinity but enhanced C2H2 affinity. MFSIX‐17‐Ni are consequently the first physisorbents that enable single‐step production of polymer‐grade ethylene (>99.95 % for SIFSIX‐17‐Ni) from a ternary equimolar mixture of ethylene, acetylene and CO2 thanks to coadsorption of the latter two gases. We attribute this performance to the very different binding sites in MFSIX‐17‐Ni versus SIFSIX‐3‐Zn.

AbstractReduction of (CAAC)BBr2(NCS) (CAAC=cyclic alkyl(amino)carbene) in the presence of a Lewis base L yields tricoordinate (CAAC)LB(NCS) borylenes which undergo reversible E/Z‐isomerization. The same reduction in the absence of L yields deep blue, bis(CAAC)‐stabilized, boron‐doped, aromatic thiazolothiazoles resulting from the dimerization of dicoordinate (CAAC)B(NCS) borylene intermediates.

Published: January 2021

AbstractThe 10‐nuclear heteroatom cluster modified {SbW8O30} was successfully synthesized and exhibited inhibitory activity (IC50=0.29 μM). Based on proteomics analysis, Na4Ni2Sb2W2‐SbW8 inhibited ATP production by affecting the expression of 16 related proteins, hindering metabolic functions in vivo and cell proliferation due to reactive oxygen species (ROS) stress. In particular, the low expression of FAD/FMN‐binding redox enzymes (relative expression ratio of the experimental group to the control=0.43843) could be attributed to the redox mechanism of Na4Ni2Sb2W2‐SbW8, which was consistent with the effect of polyoxometalates (POMs) and FMN‐binding proteins on ATP formation. An electrochemical study showed that Na4Ni2Sb2W2‐SbW8 combined with FMN to form Na4Ni2Sb2W2‐SbW8‐2FMN complex through a one‐electron process of the W atoms. Na4Ni2Sb2W2‐SbW8 acted as catalase and glutathione peroxidase to protect the cell from ROS stress, and the inhibition rates were 63.3 % at 1.77 μM of NADPH and 86.06 % at 10.62 μM of 2‐hydroxyterephthalic acid. Overall, our results showed that POMs can be specific oxidative/antioxidant regulatory agents.

PREMISENew sequencing technologies facilitate the generation of large‐scale molecular data sets for constructing the plant tree of life. We describe a new probe set for target enrichment sequencing to generate nuclear sequence data to build phylogenetic trees with any flagellate land plants, including hornworts, liverworts, mosses, lycophytes, ferns, and all gymnosperms.METHODSWe leveraged existing transcriptome and genome sequence data to design the GoFlag 451 probes, a set of 56,989 probes for target enrichment sequencing of 451 exons that are found in 248 single‐copy or low‐copy nuclear genes across flagellate plant lineages.RESULTSOur results indicate that target enrichment using the GoFlag451 probe set can provide large nuclear data sets that can be used to resolve relationships among both distantly and closely related taxa across the flagellate land plants. We also describe the GoFlag 408 probes, an optimized probe set covering 408 of the 451 exons from the GoFlag 451 probe set that is commercialized by RAPiD Genomics.CONCLUSIONSA target enrichment approach using the new probe set provides a relatively low‐cost solution to obtain large‐scale nuclear sequence data for inferring phylogenetic relationships across flagellate land plants.

Published: January 2021

AbstractCurved perylene diimides fused with seven‐membered rings have been synthesized using a regioselective bay‐functionalization method and Pd‐catalyzed intramolecular C−H/C−Br coupling reaction. X‐Ray analysis and temperature‐dependent NMR spectroscopy revealed the curved molecular structure with a certain degree of conformational flexibility. The curved and expanded π‐conjugation altered the electronic properties while retaining the intrinsic properties of the parent perylene diimide. Despite the absence of solubilizing N‐substituents, the curved perylene diimides showed sufficient solubility for application in solution‐processed organic photovoltaic devices. The devices showed superior performance with a power conversion efficiency of up to 2.76% due to suppressed charge recombination. Our detailed investigations suggest that the introduction of a curved structure enables the removal of the bulky N‐substituents, which is an effective way to achieve a thin‐film morphology suitable for photoelectric conversion.
Cyclical inverse interpolation: An approach for the inverse interpolation of black‐box models using tensor product representations
Authors: Csapo Adam B. 
Published: January 2021

AbstractThis paper proposes a novel approach to inverse interpolating black‐box models, referred to as the cyclical inverse interpolation method (CIIM). The approach relies on the use of a multivariate surrogate function, expressed as a tensor product (TP) model, to systematically generate candidate inputs to the given black‐box model with the goal of obtaining interpolated outputs. While the proposed approach is largely agnostic as to the form of this surrogate function, some of its properties, such as the semantics of its input dimensions with respect to the black box model, are constructively defined. The paper demonstrates the viability of the proposed approach both from a theoretical perspective and through numerical examples. Based on these results, it is argued that the approach can be used for the exploratory identification of black‐box models that have scalar‐valued outputs and can be particularly useful in working with black‐box models that have a large number of inputs and exhibit highly nonlinear behavior.
Distributed impulsive control for secure consensus of nonlinear dynamical networks with node delay under denial‐of‐service attacks
Authors: Shi Yu‐Lun , Liu Zhi‐Wei 
Published: January 2021

AbstractThis paper investigates secure consensus problems of nonlinear dynamical networks (NDNs) with node delay under denial‐of‐service (DoS) attacks, which can cause a break in communication links. It will lead to packet loss. To ensure the secure consensus in this scenario, we propose an effective impulsive control which only based on sampled information from neighbor nodes. Based on the Lyapunov stability theory and the impulsive comparison principle, an upper bound of the average impulse interval is derived to ensure the exponential consensus of NDNs under DoS attacks, and the convergence rate can be estimated. Finally, a numerical example is provided to check the theory results.
Interdecadal variability of intensity of the Madden–Julian oscillation
Authors: Wang Ziyue , Li Tim , Sun Ying 
Published: January 2021

AbstractThe interdecadal variability of intensity of the Madden–Julian oscillation (MJO) during boreal winter was investigated based on two reanalysis datasets (NOAA 20CR and ERA‐20C). Both the reanalysis datasets reveal statistically significant power spectrum peaks at 12–20‐year periods. A composite analysis shows that during the active interdecadal phase, eastward propagating MJO activity was strengthened over the equatorial warm pool expanded from the Indian Ocean (IO) to the western Pacific (WP). The cause of the enhanced MJO variability was attributed to the interdecadal change of background mean precipitation in situ. A further diagnosis shows that the increase of the background precipitation over the Maritime Continent and the WP was attributed to interdecadal warm sea surface temperature (SST) anomalies in situ, whereas the increase of the precipitation over the IO resulted from the local convective instability due to the increase of wind induced surface evaporation and moisture. The strengthened background precipitation impacted the MJO strength through the increase of the interdecadal background moisture in the lower and middle troposphere induced by anomalous vertical moisture advection.

AbstractLithium‐ion capacitors (LICs), composed of a lithium ion battery (LIB)‐type electrode and an electrochemical capacitor (EC)‐type electrode (non‐Faradic), operating in a lithium ion‐containing electrolyte, have the potential to deliver high energy density, high power density and long cycle life simultaneously. In this minireview, we focus on the development of practical LICs, which has been barely introduced in previous reviews, to supplement their development course. This minireview includes the introduction of fundamentals, analysis of the key parameters, and review of the key technologies of practical LIC systems. The practical LIC technologies have been summarized and discussed in contrast to the commercial ECs. Finally, we propose the future research for LICs in terms of materials and their properties, which aims to provide guidelines for the researchers in the fields of LICs.

AbstractMany companies have developed a green marketing strategy, aimed at promoting and selling green environmental products. While the majority of articles on this topic report on studies in a business‐to‐consumer setting, this research focusses on the impact of green marketing strategies on the satisfaction and loyalty of professional buyers in a business‐to‐business setting. Hypotheses were tested with survey data from 148 Dutch professional purchasers in the cleaning industry. The results emphasize the impact and importance of product quality, product price and corporate image. The most notable and strong impact on satisfaction and loyalty was found for the salesperson expertise.
