Published: April 2023

Rice-based cropping system is a key for food security in Assam. However, the productivity of such systems has declined continuously due to deterioration in soil fertility owing mainly to faulty agricultural practices. The study was carried out to study the nutrient status of soils of the Biswanath district of Assam in the year 2021. A total of 200 no of geo-reference surface (up to 30 cm) soil samples were collected. The coefficient of variation (CV) was used for the interpretation of the variability of the indicators. Available phosphorous, available potassium DTPA-iron, DTPA-manganese, DTPA-zinc, and DTPA-copper were identified to be the most variable soil indicators (CV > 35%). Electrical conductivity, organic carbon, available nitrogen, and cation exchange capacity, were found as the moderately variable parameters (CV 15–35%). The least variation (CV < 15) was found pH. The mean pH, electrical conductivity and organic carbon were 5.23, 0.54 ds/m, and 0.81 percent respectively. The cation exchange capacity of the soil varied from 4.40 to 11.60 cmol(p+)/kg with the mean value of 6.74cmol(p+) /kg. The available nitrogen, available potassium and available phosphorus were 380.01kg /ha, 169.00 kg/ha and 38.01 kg/ha. The district's respective DTPA-Fe, DTPA-Cu, DTPA-Mn, and DTPA-Zn levels were found to be 83.34 mg/kg, 2.59 mg/kg, 22.25 mg/kg, and 0.79 mg/kg. The spatial distribution of each parameter was presented on the GIS platform for easy availability through IDW method of interpolation.

Published: April 2023

This paper presents a proposed Circular-shaped Antenna array for millimeter-wave application. The proposed antenna is designed to operate at mm-wave frequency of 17 GHz. Circular antennas give good return loss, and better gain and directivity. The main aim of using the array is to improve the gain of the antenna. Inset feed technique is used to design the antenna. The size and feed technique are determined by design formulas. The simulation results show a good return loss (reflection coefficient) of -55.297 dB which is way below the benchmark of 10dB and a bandwidth of 1.79 GHz (16.42 – 18.21 GHz). The gain and VSWR results are 8.684 dB and 1.0034 respectively at 17.29 GHz frequency. The CST software is used for the simulation.

ImportanceReducing violence to others in community-based patients with schizophrenia has important implications for public health. Increasing medication adherence is often used to reduce the risk of violence, yet little is known about the association between medication nonadherence and violence to others in this population.ObjectiveTo examine the association between medication nonadherence and violence to others among community-based patients with schizophrenia.Design, Setting, and ParticipantsThis large, naturalistic, prospective cohort study was performed in western China from May 1, 2006, to December 31, 2018. The data set was from the integrated management information platform for severe mental disorders. As of December 31, 2018, 292 667 patients with schizophrenia were registered in the platform. During follow-up, patients could enter or leave the cohort at any time. Maximum follow-up was 12.8 years, with a mean (SD) of 4.2 (2.3) years. Data analysis was conducted from July 1, 2021, to September 30, 2022.ExposuresMedication nonadherence.Main Outcomes and MeasuresViolence to others throughout the follow-up period was the outcome, including minor nuisances, violating the Law of the People’s Republic of China on Penalties for Administration of Public Security (APS law), and violating criminal law. Information about these behaviors was provided by the public security department. Directed acyclic graphs were used to identify and control confounders. Propensity score matching and generalized linear mixed-effects models were used for analysis.ResultsThe final study sample included 207 569 patients with schizophrenia. The mean (SD) age was 51.3 (14.5) years, and 107 271 (51.7%) were women; 27 698 (13.3%) perpetrated violence to others, including 22 312 of 142 394 with medication nonadherence (15.7%) and 5386 of 65 175 with adherence (8.3%). In 112 710 propensity score–matched cases, risks of minor nuisances (odds ratio [OR], 1.82 [95% CI, 1.75-1.90]; P &amp;lt; .001), violating APS law (OR, 1.91 [95% CI, 1.78-2.05]; P &amp;lt; .001), and violating criminal law (OR, 1.50 [95% CI, 1.33-1.71]; P &amp;lt; .001) were higher in patients with nonadherence. However, the risk did not increase with higher medication nonadherence. There were differences in risk of violating APS law between urban and rural areas.Conclusions and RelevanceMedication nonadherence was associated with a higher risk of violence to others among community-based patients with schizophrenia, but the risk did not increase as medication nonadherence increased.

Abstract

Objectives
This study examined the effectiveness of a newly developed work–family life support program on the work–family interface and mental health indicators among Japanese dual-earner couples with a preschool child(/ren) using a randomized controlled trial with a waitlist.

Methods
Participants who met the inclusion criteria were randomly allocated to the intervention or the control groups (n = 79 and n = 85, respectively). The program comprised two 3-h sessions with a 1-month interval between them and provided comprehensive skills by including self-management, couple management, and parenting management components. The program sessions were conducted on weekends in a community center room with 3–10 participants. Outcomes were assessed at baseline, 1-month, and 3-month follow-ups. Primary outcomes were work–family balance self-efficacy (WFBSE), four types of work–family spillovers (i.e., work-to-family conflict, family-to-work conflict, work-to-family facilitation, and family-to-work facilitation), psychological distress, and work engagement reported by the participants.

Results
The program had significantly pooled intervention effects on WFBSE (P = .031) and psychological distress (P = .014). The effect sizes (Cohen’s d) were small, with values of 0.22 at the 1-month follow-up and 0.24 at the 3-month follow-up for WFBSE, and −0.36 at the 3-month follow-up for psychological distress. However, the program had nonsignificant pooled effects on four types of work–family spillovers and work engagement.

Conclusions
The program effectively increased WFBSE and decreased psychological distress among Japanese dual-earner couples with a preschool child(/ren).

Published: April 2023

AbstractThis study analyzed the flexural buckling behavior of light‐gauge built‐up compression members joined by self‐drilling screws by using the energy method. A nonconventional mechanical model that simulates the flexural buckling behavior of a built‐up member was proposed, and the contradictions of Bleich's model were described. A simple design formula that directly reflects the parameters of built‐up members was derived based on the proposed model. Furthermore, to ensure flexural buckling as a single unit member, the required stiffening stiffness and number of self‐drilling screws were proposed.

Abstract3D cell cultures better replicate the in vivo environment compared to 2D models. Glioblastoma multiforme, a malignant brain tumor, highly profits from its cellular environment. Here, the U87 glioblastoma cell line in the presence/absence of primary astrocytes is studied. Thiolated hyaluronic acid (HA‐SH) hydrogel reinforced with microfiber scaffolds is compared to Matrigel. Hyaluronic acid is a major extracellular matrix (ECM) component in the brain. Poly(ɛ‐caprolactone) (PCL) scaffolds are written by meltelectrowriting in a box and triangular shaped design with pore sizes of 200 µm. Scaffolds are composed of 10‐layers of PCL microfibers. It is found that scaffold design has an impact on cellular morphology in the absence of hydrogel. Moreover, the used hydrogels have profound influences on cellular morphology resulting in spheroid formation in HA‐SH for both the tumor‐derived cell line and astrocytes, while cell viability is high. Although cocultures of U87 and astrocytes exhibit cell–cell interactions, polynucleated spheroid formation is still present for U87 cells in HA‐SH. Locally restricted ECM production or inability to secrete ECM proteins may underlie the observed cell morphologies. Thus, the 3D reinforced PCL‐HA‐SH composite with glioma‐like cells and astrocytes constitutes a reproducible system to further investigate the impact of hydrogel modifications on cellular behavior and development.

AbstractEpithelial‐to‐mesenchymal transition (EMT) is responsible for driving metastasis of multiple cancer types including lung cancer. Peroxisome proliferator‐activated receptor (PPAR)‐γ, a ligand‐activated transcription factor, controls expression of variety of genes involved in EMT. Although several synthetic compounds act as potent full agonists for PPAR‐γ, their long term application is restricted due to serious adverse effects. Therefore, partial agonists involving reduced and balanced PPAR‐γ activity are more effective and valued. A previous study discerned the efficacy of quercetin and its derivatives to attain favorable stabilization with PPAR‐γ. Here this work is extended by synthesizing five novel quercetin derivatives (QDs) namely thiosemicarbazone (QUETSC)) and hydrazones (quercetin isonicotinic acid hydrazone (QUEINH), quercetin nicotinic acid hydrazone (QUENH), quercetin 2‐furoic hydrazone (QUE2FH), and quercetin salicyl hydrazone (QUESH)) and their effects are analyzed in modulating EMT in lung cancer cell lines via PPAR‐γ partial activation. QDs‐treated A549 cells diminish cell proliferation strongly at nanomolar concentration compared to NCI‐H460 cells. Of the five screened derivatives, QUETSC, QUE2FH, and QUESH exhibit the property of partial activation as compared to the overexpressive level of rosiglitazone. Consistently, these QDs also suppress EMT process by markedly downregulating the levels of mesenchymal markers (Snail, Slug, and zinc finger E‐box binding homeobox 1) and concomitant upregulation of epithelial marker (E‐cadherin).

Published: April 2023

AbstractNanovaccine‐based immunotherapy can initiate strong immune responses and establish a long‐term immune memory to prevent tumor invasion and recurrence. Herein, the assembly of redox‐responsive antigen nanoparticles (NPs) conjugated with imidazoquinoline‐based TLR7/8 agonists for lymph node‐targeted immune activation is reported, which can potentiate tumor therapy and prevention. Antigen NPs are assembled via the templating of zeolitic imidazolate framework‐8 NPs to cross‐link ovalbumin with disulfide bonds, which enables the NPs with redox‐responsiveness for improved antigen cross‐presentation and dendritic cell activation. The formulated nanovaccines promote the lymphatic co‐delivery of antigens and agonists, which can trigger immune responses of cytotoxic T lymphocytes and strong immunological memory. Notably, nanovaccines demonstrate their superiority for tumor prevention owing to the elicited robust antitumor immunity. The reported strategy provides a rational design of nanovaccines for enhanced cancer immunotherapy.

Published: April 2023

AbstractConstructing a homogenous and inorganic‐rich solid electrolyte interface (SEI) can efficiently improve the overall sodium‐storage performance of hard carbon (HC) anodes. However, the thick and heterogenous SEI derived from conventional ester electrolytes fails to meet the above requirements. Herein, an innovative interfacial catalysis mechanism is proposed to design a favorable SEI in ester electrolytes by reconstructing the surface functionality of HC, of which abundant CO (carbonyl) bonds are accurately and homogenously implanted. The CO (carbonyl) bonds act as active centers that controllably catalyze the preferential reduction of salts and directionally guide SEI growth to form a homogenous, layered, and inorganic‐rich SEI. Therefore, excessive solvent decomposition is suppressed, and the interfacial Na+ transfer and structural stability of SEI on HC anodes are greatly promoted, contributing to a comprehensive enhancement in sodium‐storage performance. The optimal anodes exhibit an outstanding reversible capacity (379.6 mAh g−1), an ultrahigh initial Coulombic efficiency (93.2%), a largely improved rate capability, and an extremely stable cycling performance with a capacity decay rate of 0.0018% for 10 000 cycles at 5 A g−1. This work provides novel insights into smart regulation of interface chemistry to realize high‐performance HC anodes for sodium storage.

AbstractThe discovery of extracellular electron conduits has spurred new applications in microbial electronics. Except for a limited number of exoelectrogens, most microbes are surrounded by insulating membranes that impair extracellular electron transfer. This study focuses on the fabrication of a conductive polypyrrole (PPy) coating for enhancing microbial charge extraction. The polymer deposition is characterized and optimized using a combination of potentiodynamic and potentiostatic measurements as well as scanning electron microscopy (SEM), energy dispersive X‐Ray (EDX) analysis, and Raman spectroscopy. The electrodes are used to extract photosynthetic electrons from the cyanobacteria Synechocystis sp. PCC6803 (Synechocystis) and Synechococcus Elongatus PCC7942 (Elongatus). The PPy electrode shows a sixfold increase in extracted photocurrent for Synechocystis under unmediated conditions compared to bare graphite electrodes. This enhancement is attributed to the decreased resistance and increased electroactive surface area of the PPy electrode. By contrast, Elongatus shows no substantial difference in photocurrent between the PPy and bare electrodes. Compared to Synechocystis cells, the Elongatus cells show limited electrode adherence with weaker charge interactions. These findings lay the framework for designing customized polymer electrodes for strain‐specific charge extraction.
Copper Composites and Laser Sintering: Novel Hybridization Method for 3D Printed Electronics
Authors: Rafael Rémi , Chan Paddy K. L. 
Published: April 2023

AbstractAdditive manufacturing of electronic devices is challenging because plastics and metals, which are both required as insulator and conductor, respectively, have very distinct thermal properties. Despite significant research efforts, the currently available electronic‐printing methods are still limited by low printing speeds and high manufacturing costs. In this work, a hybrid printing method is proposed that combines fused deposition modeling (FDM) with laser sintering to print thermoplastics and copper in a single process. A copper and copper‐oxide composite filament is developed that is compatible with FDM printing. The composite undergoes in situ reduction under laser exposure and produces a highly conductive copper network. Using the home‐developed 3D printer, 3D conductive vias embedded in thermoplastic dielectric are demonstrated. The printed copper electrodes have low resistivity of 4 × 10−4Ω cm and are compatible with soldering. This novel metal‐deposition approach and setup prove a novel concept for developing modern electronics using additive manufacturing.

Published: April 2023

AbstractReliability and lifetime estimation of implantable medical devices (IMDs) is one of the essential steps in their design and development. As any failure of IMDs can result in serious health risks for the patients, they should be guaranteed not to fail over their intended lifetime under the harsh body fluidic and chemical environments. Traditional leak tests are applicable to large cm‐scale IMDs, and they are often destructive, laborious, and costly. This paper presents an automated and wireless accelerated heat soak testing system to assess hermetic failure mechanisms in small mm‐sized inductively powered IMDs. A high‐throughput readout coil array printed circuit board can test hermeticity of multiple mm‐sized wireless IMDs simultaneously in a harsh environment (e.g., 45 °C/90% RH with an error range of ±0.2% for 18 days gage repeatability and reproducibility test). An accelerated heat soak test is performed to evaluate the electronic durability and estimate the lifetime of the IMDs. This work focuses on validating the proposed system interrogating with eight inductor–capacitor sensors, composed of an interdigitated capacitive sensor connected to an inductor patterned polyimide substrate, to examine hermetic failure mechanisms of parylene‐C encapsulation for wireless IMDs as well as broader miniature‐sized consumer electronics.

AbstractA composite with shape memory‐assisted self‐healing and piezoresistive sensing ability is presented herein, and its high conductivity is attributed to a small amount of well‐dispersed carbon black (CB). Carboxylic acid groups are introduced into the polyvinyl butyral (PVB) side chain via the ring‐opening reaction of succinic anhydride. Thus, CB is well‐dispersed in the solution owing to simultaneous attraction and electrostatic repulsion. The resulting ink with less than 30 wt.% CB is highly conductive (3.7 S cm−1). In addition, hexamethylene diisocyanate (HDI) is used as a crosslinking agent to promote the reaction between OH and COOH in the side chains of the PVB‐COOH. The dual network consisting of urethane and amide bonds exhibits the shape memory effect. Moreover, the composite is shown to be capable of shape memory‐assisted self‐healing owing to the hydrogen bonds between the dual network and COOH, such that the resistance returns to its initial value, and the healed sample can support a 1 kg weight. The resulting multi‐modal sensing system is shown to detect bio‐signals such as body movements, breathing, and pulse. In summary, the present work provides an effective strategy for the development of conductive composite electrodes for various applications that require adaptability and piezoresistive sensing ability.

Published: April 2023

AbstractThe structural stability and durability of a sensing device at high‐temperatures (HT) have important effects on its functionality and reliability. This becomes more critical in the devices that work based on the surface acoustic waves (SAW). In this study, the thermomechanical and creep behaviors of the metallization systems, RuAl, MoLa, and Mo suggested for the electrodes of HT‐SAW sensors are investigated. Several experiments are designed to obtain the state and the value of stress in the films deposited on a Si [100] substrate caused by the fabrication process and the operational conditions. Results show that after the film deposition, the intrinsic compressive stress in the MoLa film is significantly lower than the other films. However, after annealing the samples, the lowest residual stress is reached in the Mo. Linear stress variations during the thermal cycling of the annealed samples are obtained for all metallizations. To study the durability of the films at HT, the creep behavior of the samples is investigated by keeping them at a temperature of 600 °C for 10 h. The creep rate and its constitutive equation for the films are obtained. It is observed that the creep rate of MoLa and Mo films is much lower than RuAl.
