An in silico prediction of interaction models of influenza A virus PA and human C14orf166 protein from yeast‐two‐hybrid screening data
Authors: Çağlayan Elif , Turan Kadir 
Published: June 2023

AbstractThe human C14orf166 protein, also known as RNA transcription, translation, and transport factor, shows positive modulatory activity on the cellular RNA polymerase II enzyme. This protein is a component of the tRNA‐splicing ligase complex and is involved in RNA metabolism. It also functions in the nucleo‐cytoplasmic transport of RNA molecules. The C14orf166 protein has been reported to be associated with some types of cancer. It has been shown that the C14orf166 protein binds to the influenza A virus RNA polymerase PA subunit and has a stimulating effect on viral replication. In this study, candidate interactor proteins for influenza A virus PA protein were screened with a Y2H assay using HEK293 Matchmaker cDNA. The C14orf166 protein fragments in different sizes were found to interact with the PA. The three‐dimensional structures of the viral PA and C14orf166 proteins interacting with the PA were generated using the I‐TASSER algorithm. The interaction models between these proteins were predicted with the ClusPro protein docking algorithm and analyzed with PyMol software. The results revealed that the carboxy‐terminal end of the C14orf166 protein is involved in this interaction, and it is highly possible that it binds to the carboxy‐terminal of the PA protein. Although amino acid residues in the interaction area of the PA protein with the C14orf166 showed distribution from 450th to 700th position, the intense interaction region was revealed to be at amino acid positions 610–630.
A novel approach to modeling steady‐state process‐time with smooth transition from repetitive to semi‐repetitive to non‐repetitive (memoryless) processes
Authors: Shore Haim 
Published: June 2023

AbstractDefining properly the time distribution of a steady‐state process is crucial to its management. A common practice is to assume that process‐time is normally distributed for repetitive processes (process has constant work‐content), and exponentially for non‐repetitive processes (memoryless; no characteristic work‐content). This dichotomous distinction ignores the majority of processes, residing in between the two extreme scenarios, the semi‐repetitive ones. These processes own a characteristic duration time (as reflected in the mode), yet part of work‐content (“process identity”) randomly varies between cycles. In this paper, we develop a unified platform to model process‐time, comprising all three types of processes. The effects of work‐content instability on shape characteristics of process‐time distribution are studied, and process repetitiveness measure, possibly to be used to monitor work‐content instability, is defined. The generalized gamma distribution is employed to approximate the (unknown) distribution of process‐time sample mean, becoming exact for the two extreme scenarios (repetitive and non‐repetitive processes).

AbstractAimTo describe factors associated with women's knowledge of nutrition, knowledge of nutrient supplements and use of supplements that are routinely recommended during preconception and pregnancy.MethodsParticipants (women 18–45 years, pregnant or planning pregnancy) were recruited from a consumer survey panel and completed an online, custom‐built questionnaire. Responses were used to calculate individual scores for nutrition knowledge (range 0–30) and supplements knowledge (range 0–10), where higher scores indicated better knowledge, and determine use of routinely recommended supplements (yes/no). Statistical tests of independence were used to explore associations between these outcomes and 68 variables derived from the survey.ResultsOf 2289 respondents, 776 were eligible and 624 (80.4%) completed the survey. Among pregnant women (N = 144) and those planning a pregnancy (N = 480), nutrition knowledge and supplements knowledge was limited, and daily use of routinely recommended supplements was low (63.5% pregnant, 40.1% planners). The odds of appropriate supplement use was strongly associated with health literacy adequacy. There was a low positive correlation between supplements beliefs and nutrition/supplements knowledge. Nutrition and supplements knowledge was associated with information provided by a wider number of health and allied health services during preconception than during pregnancy.ConclusionHealthcare providers are central to preconception and pregnancy dietary and nutrient supplement advice. Our data reinforce the role of adequate health literacy in applying this advice and suggest that an understanding of women's beliefs about supplements and targeting the source of the information to women at different stages (preconception or pregnant), could be used to better tailor these communications.

Published: June 2023

AbstractThis article is concerned with data‐driven analysis and controller design for continuous‐time sampled‐data systems. The linear system considered in this paper is controlled under the periodic event‐triggering transmission mechanism. Firstly, the periodic event‐triggered control (PETC) systems are modeled and analyzed by the time‐delay approach. And model‐based stability conditions are presented by invoking the Lyapunov stability approach. Secondly, based on the model‐based conditions and a popular data‐based representation, data‐based stability criteria are deduced by using only noisy data. The stability criteria guarantee the stability properties robustly for all unknown systems consistent with the measured data. The data‐driven estimation of the maximum detecting interval (MDI) is also obtained directly without model knowledge. Beyond that, the data‐based method for the controller design as well as computing a possibly large MDI under various triggering parameters is put forth. Finally, the effectiveness of the proposed methods is demonstrated by the numerical simulation and the hardware‐in‐the‐loop (HIL) experiment.
Combined H∞ and anti‐disturbance control for semi‐Markovian jump systems via a nonlinear disturbance observer

Published: June 2023

AbstractThis paper investigates a combined and anti‐disturbance control problem for a class of semi‐Markovian jump nonlinear systems with constant time delay, and both modeled and unmodeled disturbances. In particular, the modeled disturbance is thought to be produced by a nonlinear exogenous system and is estimated by introducing a mode‐dependent nonlinear disturbance observer. The desired controller for the addressed system is then proposed, which consists of two components: (i) state feedback, which ensures the system's stochastic stability by attenuating the unmodeled disturbance; and (ii) disturbance estimate, which compensates for the modeled disturbance effect. Following that, a novel mode‐dependent asymmetric Lyapunov‐Krasovskii functional is used to derive the sufficient conditions for the existence of the proposed controller and disturbance observer. The developed theoretical results are supported by three numerical examples that demonstrate the utility of the proposed design method.

The presence of Si on the Ti surface is quintessential for a strong, durable silane‐based adhesion utilized in several dental applications. Silica‐coating and silanization form durable ≡Si‐O‐Si≡ bonds, which might have a positive effect on resin‐Ti adhesion. This laboratory study studied the effect of strong acids, their blends, and silica‐coating on Ti and resin‐Ti bonding. One‐hundred sixty‐eight c.p. grade 2 polished Ti samples (10 mm × 10 mm × 1 mm), out of which 96 were etched with 9% and 12%HF, a blend of 35%HCl+85%H3PO4 and a blend of 69%HNO3+35%HCl at 60°C, each for 2 min. One half was silica‐coated (Rocatec™ Plus, 110 μm SiO2‐coated‐Al2O3). Sixty Ti samples were first silica‐coated, and then, 48 of them were etched with 9%HF, 12%HF, a blend of 35%HCl+85%H3PO4, and a blend of 69%HNO3+35%HCl at 60°C for 2 min. SEM, EDX, XPS, and Ra analyses were carried out. Polished Ti samples were controls. All silanizations were carried out with a blend of 0.3 vol% 1,2‐bis‐(triethoxysilyl)ethane+1.0 vol% 3‐acryloxypropyltrimethoxysilane. Multilink™ Automix self‐adhesive resin composite cement was used in adhesion testing, and the samples were artificially aged followed by enclosed‐mold micro‐shear test on day 1 and weeks 1, 4, and 8. Failure mode analysis and statistical analysis with one‐way/two‐way ANOVA (p < 0.05) were carried out. HF etching produced the highest surface roughness. XPS analysis identified after etching with HF a variety of Ti and Si ions: Ti4+, Ti3+, Ti2+, and Ti0 and, on the other hand, Si4+, Si3+, and Si2+. A gradual decrease in adhesion strength was observed after artificial aging. Adhesive and cohesive failures were observed.

AbstractHybrid organic–inorganic perovskites (HOIPs) have shown great promise in a wide range of optoelectronic applications. However, this performance is inhibited by the sensitivity of HOIPs to various environmental factors, particularly high levels of relative humidity. This study uses X‐ray photoelectron spectroscopy (XPS) to determine that there is essentially no threshold to water adsorption on the in situ cleaved MAPbBr3(001) single crystal surface. Using scanning tunneling microscopy (STM), it shows that the initial surface restructuring upon exposure to water vapor occurs in isolated regions, which grow in area with increasing exposure, providing insight into the initial degradation mechanism of HOIPs. The electronic structure evolution of the surface was also monitored via ultraviolet photoemission spectroscopy (UPS), evidencing an increased bandgap state density following water vapor exposure, which is attributed to surface defect formation due to lattice swelling. This study will help to inform the surface engineering and designs of future perovskite‐based optoelectronic devices.

AbstractGraphene‐based materials (GBMs) have promising applications in various sectors, including pulmonary nanomedicine. Nevertheless, the influence of GBM physicochemical characteristics on their fate and impact in lung has not been thoroughly addressed. To fill this gap, the biological response, distribution, and bio‐persistence of four different GBMs in mouse lungs up to 28 days after single oropharyngeal aspiration are investigated. None of the GBMs, varying in size (large versus small) and carbon to oxygen ratio as well as thickness (few‐layers graphene (FLG) versus thin graphene oxide (GO)), induce a strong pulmonary immune response. However, recruited neutrophils internalize nanosheets better and degrade GBMs faster than macrophages, revealing their crucial role in the elimination of small GBMs. In contrast, large GO sheets induce more damages due to a hindered degradation and long‐term persistence in macrophages. Overall, small dimensions appear to be a leading feature in the design of safe GBM pulmonary nanovectors due to an enhanced degradation in phagocytes and a faster clearance from the lungs for small GBMs. Thickness also plays an important role, since decreased material loading in alveolar phagocytes and faster elimination are found for FLGs compared to thinner GOs. These results are important for designing safer‐by‐design GBMs for biomedical application.

AbstractOrganic semiconductor single crystals (OSSCs) are ideal materials for studying the intrinsic properties of organic semiconductors (OSCs) and constructing high‐performance organic field‐effect transistors (OFETs). However, there is no general method to rapidly prepare thickness‐controllable and uniform single crystals for various OSCs. Here, inspired by the recrystallization (a spontaneous morphological instability phenomenon) of polycrystalline films, a spatial confinement recrystallization (SCR) method is developed to rapidly (even at several second timescales) grow thickness‐controllable and uniform OSSCs in a well‐controlled way by applying longitudinal pressure to tailor the growth direction of grains in OSCs polycrystalline films. The relationship between growth parameters including the growth time, temperature, longitudinal pressure, and thickness is comprehensively investigated. Remarkably, this method is applicable for various OSCs including insoluble and soluble small molecules and polymers, and can realize the high‐quality crystal array growth. The corresponding 50 dinaphtho[2,3‐b:2″,3″‐f]thieno[3,2‐b]thiophene (DNTT) single crystals coplanar OFETs prepared by the same batch have the mobility of 4.1 ± 0.4 cm2 V−1 s−1, showing excellent uniformity. The overall performance of the method is superior to the reported methods in term of growth rate, generality, thickness controllability, and uniformity, indicating its broad application prospects in organic electronic and optoelectronic devices.

AbstractThe recently developed defective 19‐electron half‐Heusler (HH) compounds, represented by Nb1−δCoSb, possess massive intrinsic vacancies at the cation site and thus intrinsically low lattice thermal conductivity that is desirable for thermoelectric (TE) applications. Yet the TE performance of defective HHs with a maximum figure of merit (zT) <1.0 is still inferior to that of the conventional 18‐electron ones. Here, a peak zT exceeding unity is obtained at 1123 K for both Nb0.7Ta0.13CoSb and Nb0.6Ta0.23CoSb, a benchmark value for defective 19‐electron HHs. The improved zT results from the achievement of selective scatterings of phonons and electrons in defective Nb0.83CoSb, using lanthanide contraction as a design factor to select alloying elements that can strongly impede the phonon propagation but weakly disturb the periodic potential. Despite the massive vacancies induced strong point defect scattering of phonons in Nb0.83CoSb, Ta alloying is still found effective in suppressing lattice thermal conductivity while maintaining the carrier mobility almost unchanged. In comparison, V alloying significantly deteriorates the carrier transport and thus the TE performance. These results enlarge the category of high‐performance HH TE materials beyond the conventional 18‐electron ones and highlight the effectiveness of selective scatterings of phonons and electrons in developing TE materials even with massive vacancies.

AbstractThe application of piezoelectric nanoparticles with shape memory polymer (SMP) to 3D‐printed piezoelectric scaffolds for bone defect repair is an attractive research direction. However, there is a significant difference in dielectric constants between the piezoelectric phase and polymer phase, limiting the piezoelectric property. Therefore, novel piezoelectric acrylate epoxidized soybean oil (AESO) scaffolds doped with piezoelectric Ag‐TMSPM‐pBT (ATP) nanoparticles (AESO‐ATP scaffolds) are prepared via digital light procession 3D‐printing. The Ag‐TMSPM‐pBT nanoparticles improve the piezoelectric properties of the AESO scaffolds by TMSPM covalent functionalization and conductive Ag nanoparticles. The AESO scaffolds doped with 10 wt% Ag‐TMSPM‐pBT nanoparticles (AESO‐10ATP scaffolds) exhibit promising piezoelectrical properties, with a piezoelectric coefficient (d33) of 0.9 pC N−1 and an output current of 146.4 nA, which are close to the piezoelectric constants of bone tissue. In addition, these scaffolds exhibit good shape memory function and can quickly recover their original shape under near‐infrared (NIR) light irradiation. The results of osteogenesis capability evaluation indicate that the AESO‐10ATP scaffolds can promote osteogenic differentiation of BMSCs in vitro and bone defect repair in vivo, indicating the 3D‐printed AESO‐10ATP piezoelectric scaffolds may have great application potential for bone regeneration.

Published: June 2023

AbstractBi2O3/rare earth oxide biphasic absorbers are attractive for high‐efficiency X‐ray shielding due to the complementary X‐ray absorption effects. However, its application is severely hindered by poor interphasic contact. Here, a new Janus interface engineering strategy is reported for the construction of continuous and flexible Bi2O3/Gd2O3 crystal nanofibrous membranes (FJNMs) with micro/nano dual self‐strengthening interphasic adhesion. This strategy facilitates online micro‐interlocking between Bi2O3/Gd2O3 nanofibers and in situ nano‐grain fusion between Bi2O3/Gd2O3 crystals, significantly enhancing the adhesive strength at the Bi2O3/Gd2O3 interface. Additionally, the synergistic shielding effect from Bi2O3/Gd2O3 absorption and multiple reflections in Bi2O3 and Gd2O3 crystal lattices make the nanofibrous membranes a superior X‐ray radiation barrier. The FJNMs demonstrate integrated features of exceptional X‐ray shielding efficiency (91%–100%), robust interfacial adhesion (lap‐shear strength >3.8 MPa), prominent flexibility, lightweight, and outstanding breathability. The design concepts of fibrosing biphasic absorber assemblies pave the way for asymmetrically assembling biphasic materials, setting the stage for a fundamental shift in next‐generation radiation shielding materials.

AbstractWith the development of bionics as well as materials science, intelligent soft actuators have shown promising applications in many fields such as soft robotics, sensing, and remote manipulation. Microfabrication technologies have enabled the reduction of the size of responsive soft actuators to the micron level. However, it is still challenging to construct microscale actuators capable of responding to different external stimuli in complex and diverse conditions. Here, this work demonstrates a dual‐stimuli cooperative responsive hydrogel microactuator by asymmetric fabrication via femtosecond laser direct writing. The dual response of the hydrogel microstructure is achieved by employing responsive hydrogel with functional monomer 2‐(dimethylamino)ethyl methacrylate. Raman spectra of the hydrogel microstructures suggest that the pH and temperature response of the hydrogel is generated by the changes in tertiary amine groups and hydrogen bonds, respectively. The asymmetric hydrogel microstructures show opposite bending direction when being heated to high temperature or exposed to acid solution, and can independently accomplish the grasp of polystyrene microspheres. Moreover, this work depicts the cooperative response of the hydrogel microactuator to pH and temperature at the same time. The dual‐stimuli cooperative responsive hydrogel microactuators will provide a strategy for designing and fabricating controllable microscale actuators with promising applications in microrobotics and microfluidics.

AbstractA hybrid composite of organic–inorganic semiconductor nanomaterials with atomic Au clusters at the interface decoration (denoted as PF3T@Au‐TiO2) is developed for visible–light‐driven H2 production via direct water splitting. With a strong electron coupling between the terthiophene groups, Au atoms and the oxygen atoms at the heterogeneous interface, significant electron injection from the PF3T to TiO2 occurs leading to a quantum leap in the H2 production yield (18 578 µmol g−1 h−1) by ≈39% as compared to that of the composite without Au decoration (PF3T@TiO2, 11 321 µmol g−1 h−1). Compared to the pure PF3T, such a result is 43‐fold improved and is the best performance among all the existing hybrid materials in similar configurations. With robust process control via industrially applicable methods, it is anticipated that the findings and proposed methodologies can accelerate the development of high‐performance eco‐friendly photocatalytic hydrogen production technologies.
