Published: August 2023

AbstractBackgroundChild irritability and anxiety are associated with parent psychological control; yet their transactional relations over time are not well‐characterized at the within‐person level. Research addressing generalizability of past Western‐based literature in non‐Western, collectivist community samples is lacking.MethodsSample comprised 285 children aged 8.8–11.4 years (145 girls; Mage = 9.9 years, SD = 0.6) in Northern Taiwan. Participants were assessed at baseline (T1), 6‐month (T2), and 12‐month (T3) follow‐ups. Child irritability and anxiety symptoms were assessed using parent‐rated Child Behavior Checklist. Parent psychological control was assessed using the parent‐ and child‐rated Psychological Control Scale. Within‐person processes were specified using the random‐intercept cross‐lagged panel models.ResultsModels showed that psychological control predicted increased child irritability when analyzing parenting data from parents and children. However, the lagged effect from psychological control to child anxiety was only seen in parent‐rated parenting data. We found limited evidence for a back‐and‐forth transactional pathway among constructs. Child irritability predicted increased child anxiety in all models.ConclusionsDirectional effects from psychological control to child irritability and anxiety support parent‐involved interventions that prioritize collaborative parenting and positive reinforcement techniques. Future validations in combined clinical and typically developing samples and direct cross‐cultural comparisons are warranted.

AbstractBackground and AimStimulant laxatives may cause electrolyte abnormalities, dehydration, and abdominal pain; their long‐term use can lead to tolerance and subsequent refractory constipation. We investigated the effectiveness, safety, and quality of life after switching from stimulant laxatives to lubiprostone in elderly patients with chronic constipation (CC).MethodsThis multicenter, interventional, open‐label, single‐arm, before‐and‐after comparison study enrolled 99 Japanese patients aged 65–90 years with CC who took stimulant laxatives for ≥2 weeks prior to switching to lubiprostone monotherapy.ResultsThe mean ± SD spontaneous defecations at Week 1 of 7.8 ± 6.2 times/week was not significantly different from that at baseline (8.3 ± 4.7). Spontaneous defecations were significantly reduced at Weeks 2 (−1.5 ± 4.0, P < 0.001) and 4 (−1.5 ± 3.7, P < 0.001). The Bristol Stool Form Scale score did not change from baseline (4.7 ± 0.9) at Weeks 1 (4.5 ± 1.3) or 4 (4.3 ± 1.3), but it did at Week 2 (4.3 ± 1.5, P < 0.05). The Patient Assessment of Constipation Quality of Life questionnaire score increased (0.36 ± 0.07, P < 0.001) after 28 days. Nausea was the only symptom that worsened from baseline and was the most frequently reported adverse drug reaction (15.2%).ConclusionSwitching to lubiprostone monotherapy for CC was not associated with significant concerns in short‐term spontaneous defecation frequency and safety, but it might affect the efficacy and patient quality of life over 2 weeks. Careful treatment strategies facilitating gradual switching to lubiprostone monotherapy may be needed in patients using stimulant laxatives.

BackgroundPatient‐friendly audiovisual (AV) systems in head MRI examinations can potentially reduce patient anxiety and contrast‐enhanced MRI (CE‐MRI) adverse reactions to gadolinium.PurposeTo evaluate whether a patient‐friendly AV system reduces the rate of adverse reactions to gadolinium‐based contrast agents.Study TypeRetrospective.PopulationFour thousand eight hundred thirty‐two outpatients (2462 female) attending for clinical CE‐MRI studies. (Gadoteridol: 1971, Meglumine gadoterate: 2733, Gadobutrol: 128.)Field Strength/SequenceRoutine CE‐MRI of head and neck using a 1.5 T or 3 T scanner with or without a patient‐friendly AV system.AssessmentOne thousand one hundred fifty‐nine patients were scanned on MRI machines equipped with patient‐friendly AV systems (AV group) and 3673 on MRI machines without AV systems (control group). Adverse reaction rate and symptoms were reviewed by referring to the system database and electronic medical records and compared between the two groups. Adverse reactions were defined as physiological reactions, such as vomiting and allergic‐like reactions, such as urticaria, occurring within 1 hour of contrast injection. We compare patient backgrounds, adverse reaction rate, adverse reactions symptoms and the severity between the two groups.Statistical TestsAdverse reaction rate with and without a patient‐friendly AV system were compared using Fisher's exact test. The relationship between patient‐friendly AV systems and the occurrence of adverse reactions was evaluated with logistic regression. Statistical significance was set at P < 0.05.ResultsOf the 4832 patients enrolled, 65 (1.35%) experienced adverse reactions. The most common adverse reactions in both groups were urticaria and pruritus. Adverse reaction rate was significantly lower in the AV group than in the control group (0.7% vs. 1.6%). No significant difference was observed in the severity (P = 1.000) of adverse reactions and symptoms (allergic‐like reaction: P = 0.08, physiologic reaction: P = 1.000) between the two groups.Data ConclusionThe patient‐friendly AV system significantly reduce adverse reaction occurrence to gadolinium‐based contrast agents.Evidence Level4Technical EfficacyStage 1

AbstractObesity increases the risk for stroke and is associated with worse post‐stroke outcomes; however, the mechanisms are poorly understood. Diet‐induced obesity leads to insulin resistance and subsequently, brain insulin deficiency. The purpose of this study was to investigate the potential impact of brain insulin deficiency on post‐stroke outcomes. To accomplish this, brain insulin levels were assessed in male C57BL/6J (B6) mice placed on either a standard diet or 54% kcal high‐fat diet, a known model of insulin resistance. Mice were subjected to either a sham surgery (control) or 30‐min middle cerebral artery occlusion to induce an ischemic stroke and administered either intranasal saline (0.9%) or intranasal insulin (1.75 U) twice daily for 5 days beginning on day 1 post‐stroke. High‐fat diet‐induced brain insulin deficiency was associated with increased mortality, neurological and cognitive deficits. On the other hand, increasing brain insulin levels via intranasal insulin improved survival, neurological and cognitive function in high‐fat diet mice. Our data suggests that brain insulin deficiency correlates with worse post‐stroke outcomes in a diet‐induced mouse model of insulin resistance and increasing brain insulin levels may be a therapeutic target to improve stroke recovery.

Published: August 2023

AbstractExtracting data from studies is the norm in meta‐analyses, enabling researchers to generate effect sizes when raw data are otherwise not available. While there has been a general push for increased reproducibility in meta‐analysis, the transparency and reproducibility of the data extraction phase is still lagging behind. Unfortunately, there is little guidance of how to make this process more transparent and shareable. To address this, we provide several steps to help increase the reproducibility of data extraction in meta‐analysis. We also provide suggestions of R software that can further help with reproducible data policies: the shinyDigitise and juicr packages. Adopting the guiding principles listed here and using the appropriate software will provide a more transparent form of data extraction in meta‐analyses.

Published: August 2023

AbstractBackgroundSoil sulfur deficiency leads to reduced crop yield and quality loss, which is especially critical for pulses as sulfur is a major component of methionine and cysteine. The present research evaluated the influence of sulfur fertilization on two varieties of navy beans grown at soil sulfur levels of 17, 26, 35, and 44 kg/ha by analyzing their composition, functionality, and protein quality.ResultsIncreasing the soil application of sulfur did not affect the protein content of the test navy bean flours. Methionine, cysteine, and tryptophan were limiting, and their concentrations were not enhanced by sulfur fertilization nor was protein digestibility. The oil holding capacity and emulsion stability were different among sulfur treatments; however, no clear trend was observed.ConclusionSulfur fertilization had only a minimal effect on the quality attributes of navy beans, possibly due to a combined effect of environmental factors that limited the plant's response to sulfur supply. Despite the limited change, the findings underlined the possible role of the environment (e.g., location, crop year, and other variables) in determining the sulfur fertilization response of navy beans and provided valuable insight for researchers to further investigate the topic and optimize navy bean production and quality.

AbstractSensing sponge materials with light weight, high elasticity, and electrical sensing properties are in enormous demand in electronic fields, but there is an imminent need to develop a scalable and facile method for the manufacture of the sensing material. Herein, an efficient in situ polymerization and convenient preparation process is reported to manufacture the microporous liquid metal/carbon nanotube‐polysulfide rubber (LM/CNT‐PSR) sponges with excellent mechanical and electrical properties, based on fluidic LMs and rigid CNTs with unique synergistic effect for sponge composites. Excellent mechanical properties of LM/CNT‐PSR sponges, such as low density, excellent elasticity, remarkable mechanical recoverability, and self‐healing property, are endowed by the interconnected microporous structure of sponge and flexible polysulfide rubber matrix with disulfide bonds. In addition, the synergistic effect of LMs and CNTs leads to excellent conductivity and unique electrical sensing property under mechanical pressure. Microporous LM/CNT‐PSR sponges with high performance and simple fabrication process are promising sensing materials for various electronic devices, such as human motion monitoring, and weighing sensing.

Published: August 2023

AbstractIt is an urgent need to develop efficient solid state cooling technologies and materials with high cycle life. Poly‐p‐phenylene benzodioxole (PBO) is a high performance fiber with excellent mechanical properties. In this work, for the first time, elasto‐ and twistocaloric cooling of PBO fibers by stretching and twisting of the PBO fiber bundles is reported. The cooling temperature reaches −0.4 and −1.3 K, for fiber stretching and twisting, respectively. A self‐coiled PBO fiber achieves maximum cooling of −3.7 K upon stretching by 35% strain, with an exceptionally high cycle life of 200 000 times. During the twisting of the PBO fibers, reversible changes in the intensity of the diffraction peaks in X‐ray diffraction patterns are observed. A strain‐sensitive color change application is realized by coating a self‐coiled PBO fiber with liquid crystallite dyes. This work provides new perspectives for PBO fibers as a high cycle‐life solid‐state refrigeration material.

Published: August 2023

AbstractHeterogeneous photocatalysts have attracted extensive attention in photo‐induced electron transfer‐reversible addition–fragmentation chain transfer (PET‐RAFT) polymerization due to their remarkable advantages such as easy preparation, tunable photoelectric properties, and recyclability. In this study, zinc (II) 5,10,15,20‐tetrakis(4‐aminophenyl)porphyrin (ZnTAPP)‐based poly‐porphyrin nanoparticles (PTAPP‐Zn) are constructed by an emulsion‐directed approach. It is investigated as a heterogeneous photocatalyst for PET‐RAFT polymerization of various methacrylate monomers under visible light exposure, and the reactions show refined polymerization control with high monomer conversions. Furthermore, it is demonstrated that the PTAPP‐Zn nanoparticles with the larger pore size enhance photocatalytic activity in PET‐RAFT polymerization. In addition, the capabilities of oxygen tolerance and temporal control are demonstrated and PTAPP‐Zn particles can be easily recycled and reused without an obvious decrease in catalytic efficiency.

Published: August 2023

AbstractAdopting only a small amount of azobenzene molecular to design liquid crystal photo‐responsive materials capable of quick response and flexible adjustability is in high demand but is challenging. Herein, azobenzenemolecules into polyurethane elastomer containing crystalline structure for preparing azobenzene liquid‐crystal elastomers (ALCEs) are demonstrated and this phenomenon of the synergistic effects between liquid crystal and crystalline phase is discovered. The key point of the work is that the synthetic ALCEs can utilize the reversible isomerism capability of azobenzene molecules under light irradiation, which can pry the motion of the macromolecular crystalline region in system to realize the large macroscopic deformation of the photo‐responsive behavior. Obviously, the ALCEs sample containing azobenzene molecule and polyethylene glycol crystallization can quickly bend, illuminated by ultraviolet light and rapidly straighten under green light. Under the same ultraviolet irradiation, the bending speed, final bending angle, recovery rate and recovery ratio of ALCEs are larger than that of ALCEs without any crystalline structure. This ALCEs based on the synergistic effects between liquid crystal and crystalline phase can break through the current dilemma that the application of traditional azobenzene photo‐responsive materials is limited by their concentration, greatly expanding the design thought and their scope of application.

Published: August 2023

AbstractBackground: Despite tremendous efforts made by scientific community during the outbreak of COVID‐19 pandemic, this disease still remains as a public health concern. Although different types of vaccines were globally used to reduce the mortality, emergence of new variants of SARS‐CoV‐2 is a challenging issue in COVID‐19 pharmacotherapy. In this context, target therapy of SARS‐CoV‐2 by small ligands is a promising strategy. Methods: In this investigation, we applied ligand‐based virtual screening for finding novel molecules based on nirmatrelvir structure. Various criteria including drug‐likeness, ADME, and toxicity properties were applied for filtering the compounds. The selected candidate molecules were subjected to molecular docking and dynamics simulation for predicting the binding mode and binding free energy, respectively. Then the molecules were experimentally evaluated in terms of antiviral activity against SARS‐CoV‐2 and toxicity assessment. Results: The results demonstrated that the identified compounds showed inhibitory activity towards SARS‐CoV‐2 Mpro. Conclusion: In summary, the introduced compounds may provide novel scaffold for further structural modification and optimization with improved anti SARS‐CoV‐2 Mpro activity.
Implementing the slice method to evaluate lateral pile capacity in cohesive soil
Authors: Gans‐Or Tomer , Pinkert Shmulik 
Published: August 2023

AbstractThis paper presents a novel method for evaluating the resistance factor used for the estimation of lateral pile capacity in cohesive soil. The developed method uses limit equilibrium and mobilized strength principles, which are implemented on the half‐symmetric problem using a modification of the traditional slice method. The soil medium is discretized into a polar numerical grid, allowing sliplines investigation independently of geometrical shape assumptions. The paper presents the development of the SLIP (Snake Locomotion Iterative Procedure) optimization method, which enables an effective and efficient search of the critical slipline out of all slipline geometries that can be generated within the numerical grid. The SLIP iteratively updates the evaluated optimal slipline, according to the criterion of minimizing the pile resistance factor, N. The obtained solutions are consistent with previous plasticity results, with special attention to the smooth pile solution which is bounded between the best lower‐ and upper‐bounds solutions to date. The work utilizes safety map principles to prove the uniqueness of the solution.
Accurate bidiagonal decomposition of Lagrange–Vandermonde matrices and applications
Authors: Marco Ana , Martínez José‐Javier , Viaña Raquel 
Published: August 2023

AbstractLagrange–Vandermonde matrices are the collocation matrices corresponding to Lagrange‐type bases, obtained by removing the denominators from each element of a Lagrange basis. It is proved that, provided the nodes required to create the Lagrange‐type basis and the corresponding collocation matrix are properly ordered, such matrices are strictly totally positive. A fast algorithm to compute the bidiagonal decomposition of these matrices to high relative accuracy is presented. As an application, the problems of eigenvalue computation, linear system solving and inverse computation are solved in an efficient and accurate way for this type of matrices. Moreover, the proposed algorithms allow to solve fastly and to high relative accuracy some of the cited problems when the involved matrices are collocation matrices corresponding to the standard Lagrange basis, although such collocation matrices are not totally positive. Numerical experiments illustrating the good performance of our approach are also included.

Published: August 2023

AbstractLarge tow carbon fiber reinforced polymer (CFRP) has been used to reinforce structures serving in hygrothermal conditions, which can be greatly affected by hygrothermal conditions. In this study, the hygrothermal resistance of 48K and 12K carbon fibers and their CFRPs immersed in deionized water at 25, 40, and 60°C were analyzed and compared. The sizing agent on the carbon fiber surface was deboned or hydrolyzed after immersion, resulting in a reduction in the tensile strength, an increase in dispersion, and a decrease in surface activity for carbon fibers. The retention rate of tensile strength of 48K CFRP was higher than 89.7% but was less than that of 12K CFRP due to the higher dispersion of 48K fiber filaments. The interlaminar shear strength (ILSS) and Mode I interlaminar fracture toughness of 48K CFRP was greater than 12K CFRP due to the higher fiber surface activity of 48K carbon fibers and the stronger obstructing effect of 48K fiber tows on the diffusion of water. The degrees of post‐curing and hydrolysis of CFRP were less than 10%. The degradation of the fiber‐matrix interface and a decrease in the strength and elastic modulus of the matrix led to the degradation of the tensile properties, ILSS, and Mode I interlaminar fracture toughness of CFRP.Highlights
Debonding of sizing agent reduced the strength of the carbon fiber filaments.
Degrees of hydrolysis and post‐curing of the matrix caused by immersion were low.
Retentions of ILSS and fracture toughness of 48K CFRP were higher than 12K CFRP.
48K fiber tow possessed a stronger obstructing effect on water diffusion.
Investigation and characterization of dielectric, thermal, and chemical properties of recycledhigh‐density polyethyleneblended with virginpolyethylene

Published: August 2023

AbstractDielectric performance of post‐consumer recycled HDPE blended with virgin HDPE was investigated to evaluate the possibility of using these materials for the insulation of electrical wires and cables. The presence of organic and inorganic impurities was investigated using thermal and chemical methods (TGA, DSC, and EDX). The characterization of impurities revealed different amount of inorganic impurities in recycled material that was depending on the execution of melt filtration by the recycler to prepare the recycled material. Higher values of both dielectric losses and dielectric constant were observed for post‐consumer recycled PE, with the dielectric loss of recycled material almost 17 times higher than the one of virgin PE at power frequency (60 Hz). The short‐term breakdown strength of post‐consumer recycled HDPE was observed to be slightly lower than that of virgin PE. The experimental result showed that blending the recycled stream with virgin materials was effective in order to enhance dielectric properties of recycled material. In this regards, dielectric losses decreased by almost 50% when 50% of virgin HDPE was added to the recycled material. In addition, breakdown strength was improved when virgin HDPE was added.
