Published: January 2023

This work aimed to determine the effect of biodegradable superabsorbent hydrogel based on cellulose derivatives on the growth and yield of sweet corn (Zea mays saccharata Sturt) on dry land. The design used was a completely randomized design (CRD). The applied treatments consisted of four levels of hydrogel: without
hydrogel (control), 2, 4, and 6 g per plant, respectively. Each treatment was repeated six times in this experiment, yielding a total of 24 experimental pots. Each experiment pot contained 3 plants, thus all 72 plants. The results showed that the hydrogel would significantly increase soil moisture, relative water content, growth of the plant height, stem diameter, and ear cobs without corn husk. Likewise, on the length of the ear without ear cobs and wet ear weights without corn husk. As the hydrogel preserves soil moisture, allowing water to be available for the plant, it might also temporarily store soil from the water and gradually remove it into the soil. Further investigations should be performed to completely characterize the interaction between the superabsorbent hydrogel and the dry land soil.

AbstractOrganic semiconductor nanocrystals are important building blocks for miniaturized room‐temperature optoelectronic and excitonic devices, benefitting from their large oscillator strength, high quantum yield, and large exciton binding energy. Specifically, 1D organic semiconductor nanowires have been widely studied with promising applications such as nanoscale light sources and optical waveguides. Although both amplified spontaneous emission and lasing have been well demonstrated in organic semiconductor nanowires under pulsed laser excitation, amplification of guided photons during propagation along the nanowire has been rarely investigated. Here, a highly polarized luminescent organic semiconductor nanowire with self‐amplified photon guiding capability under continuous‐wave laser excitation is reported. The nanowire waveguide itself functions as a gain medium to provide optical gain during its photoluminescence propagation, with the value of gain depending on temperature and excitation laser power. This research reveals the optical gain effect in the organic semiconductor waveguide system, which paves the way for on‐chip energy‐efficient photonic communications.

Published: January 2023

AbstractStatistische Auswertungen von Brückeneinsturzdaten zeigen, dass Massivbrücken signifikant seltener einstürzen als Brücken aus Stahl oder Holz. Da weltweit die Hauptursache für Brückeneinstürze Hochwasser und damit verbundene fluviale Prozesse wie Auskolkung, Muren etc. und Anpralle sind, liegt die Vermutung nahe, dass die hohe Eigenlast der Massivbrücken zu einem insgesamt robusteren Verhalten bei diesen Ereignissen führt. Im Rahmen dieses Beitrags soll geprüft werden, ob die IABSE‐Einsturzdatenbank diese These bestätigt und Hinweise auf weitere Ursachen identifiziert werden können. Dazu wird die IABSE‐Einsturzdatenbank mittels Verfahren der Künstlichen Intelligenz und des maschinellen Lernens (KI/ML) untersucht. Die KI/ML‐Analyse bestätigt die bisherige These allerdings nicht. Im Weiteren werden Ursachen für die Ablehnung der These, wie z. B. die Repräsentativität der Daten, diskutiert. Es wird eine Erweiterung der Datenbank für Ereignisse mit großen Einsturzzahlen empfohlen.

Published: January 2023

SummaryInternet of recent decades considered cloud computing as the most effective and distributed platform. It is a comfortable and quick way to access shared resources over the Internet anytime. The major problem cloud customers face while choosing the resources for a particular application is QoS. In the cloud computing environment, various resources need to be effectively allocated on VMs by reducing makespan and synchronously increasing resource utilization. For that, a novel multi‐objective hybrid capuchin search with genetic algorithm (MHCSGA) based hierarchical resource allocation is established in this work. MHCSGA optimizes the multi‐objective functions like resource utilization, response time, makespan, execution time and throughput. Initially, partitioning around the K‐medoids clustering method is utilized to allocate the resources optimally. During clustering, the tasks are divided into two cluster groups then, the optimization is performed to attain an optimal resource allocation process. The experimental setup is executed using the JAVA tool. For the simulation process, the proposed work uses the GWA‐T‐12 Bitbrains dataset. The makespan achieved by proposed algorithm for 50, 100, 150, and 200 tasks are found to be 10.45, 17.6, 25.67, and 31.34, respectively. The comparison analysis proves that the developed model attains improved performance than the state‐of‐the‐art works.

AbstractGreen hydrogen, using sustainable energy to decompose water to produce hydrogen, is regarded as the ideal and effective connection to convert electricity into chemical energy. Herein, well designed Ni‐doped Mo2C nanorod electrodes self‐supported on three types of substrates (Ni foam, Cu foam and stainless steel wire mesh) with outstanding gas resistance and prominent corrosion resistance were assembled together to build up a wide pH applicable electrode for Hydrogen Evolution. In particular, Ni‐doped Mo2C nanorod arrays on stainless steel wire mesh donated as Ni−Mo2C@SSW exhibited remarkable electrocatalytic properties towards hydrogen evolution reaction with superior overpotentials both in 1 M KOH and 0.5 M H2SO4 (102 mV and 106 mV at the current density of 10 mA cm−2) and incomparable continuous durability. This work provides the possibility for the realization of low cost, high activity and ultra‐stable durability HER electrocatalysts in practical industrial application.

AbstractDisordered cellular development, abnormal neuroanatomical formations, and dysfunction of neuronal circuitry are among the pathological manifestations of cortical regions in the brain that are often implicated in complex neurodevelopmental disorders. With the advancement of stem cell methodologies such as cerebral organoid generation, it is possible to study these processes in vitro using 3D cellular platforms that mirror key developmental stages occurring throughout embryonic neurogenesis. Patterning‐based stem cell models of directed neuronal development offer one approach to accomplish this, but these protocols often require protracted periods of cell culture to generate diverse cell types and current methods are plagued by a lack of specificity, reproducibility, and temporal control over cell derivation. Although ectopic expression of transcription factors offers another avenue to rapidly generate neurons, this process of direct lineage conversion bypasses critical junctures of neurodevelopment during which disease‐relevant manifestations may occur. Here, we present a directed differentiation approach for generating human pluripotent stem cell (hPSC)‐derived cortical organoids with accelerated lineage specification to generate functionally mature cortical neurons in a shorter timeline than previously established protocols. This novel protocol provides precise guidance for the specification of neuronal cell type identity as well as temporal control over the pace at which cortical lineage trajectories are established. Furthermore, we present assays that can be used as tools to interrogate stage‐specific developmental signaling mechanisms. By recapitulating major components of embryonic neurogenesis, this protocol allows for improved in vitro modeling of cortical development while providing a platform that can be utilized to uncover disease‐specific mechanisms of disordered development at various stages across the differentiation timeline. © 2023 Wiley Periodicals LLC.Basic Protocol 1: 3D hPSC neural inductionSupport Protocol 1: Neural rosette formation assaySupport Protocol 2: Neurosphere generationSupport Protocol 3: Enzymatic dissociation, NSC expansion, and cryopreservationBasic Protocol 2: 3D neural progenitor expansionBasic Protocol 3: 3D accelerated cortical lineage patterning and terminal differentiation
Nocturnal surveys of lined seahorses reveal increased densities and seasonal recruitment patterns

Published: January 2023

AbstractAlthough the nighttime ecology of organisms remains understudied, nocturnal surveys play an integral part in assessing fish assemblages and the selective forces shaping them. Eleuthera (Bahamas) contains an unusual population of lined seahorses (Hippocampus erectus) in an anchialine lake, possessing morphological characteristics distinct from those found in the ocean. Population surveys for seahorses and their potential predators were conducted at midnight and midday during wet and dry seasons, with belt transects perpendicular to the shoreline that increased in depth away from shore. Nocturnal surveys uncovered seahorse densities 259% higher than daytime transects on average. Sex ratios were consistently male‐biased, and the frequency of animals from different reproductive categories varied significantly by time of day, with gravid males observed around the clock but females and nongravid males observed more often at night. Spatial and seasonal recruitment was detected for the first time in this species, with an increase in juveniles detected in the shallow ends of transects during dry season surveys. Juvenile recruitment is poorly understood across syngnathid fishes, so the detection of early recruits at night has broad implications for this fish family. Seahorses from all reproductive categories were perched significantly higher in the water column during the night regardless of their depth or season. Predator densities followed a similar pattern with higher densities observed at night, indicating that elevated nocturnal perch height may be a response to predator presence. However, the selective agents driving these nocturnal behaviors have yet to be identified. Considering H. erectus is listed on the IUCN Red List as “Vulnerable,” the increase in nocturnal population size and the detection of juveniles has crucial implications for understanding their ecology, recruitment, and conservation.

AbstractDespite high‐efficiency and low production cost, material toxicity of lead‐containing metal halide perovskite solar cells (PSCs) has been considered a major challenge towards its practical commercialization and widespread applications. With forefront efforts to develop alternative Pb‐free compositions, there have been increasing research efforts in recent years to mitigate the toxicity of Pb in PSCs. Herein, we review the key technologies for mitigating the toxicity of Pb in PSCs. First, we reviewed the status of Pb‐free PSC research, followed by an exploration of strategies for immobilizing and recycling Pb in Pb‐based PSCs. Finally, the perspectives for future development are discussed. Realistically, the complete elimination of Pb from commercially competitive PSCs might require a considerable amount of time and resources. Thus, strategies for risk management of available Pb‐based PSCs are essential for commercialization of sustainable and environmentally viable PSCs.image

Published: January 2023

IntroductionAdrenal cysts are relatively rare and often asymptomatic. Surgical treatment is indicated for symptomatic cases with cysts >6 cm, suspected bleeding, and those that cannot be distinguished from malignant illness based on imaging findings. There have often been cases of giant cysts that were difficult to treat using laparoscopic surgery.Case presentationA 39‐year‐old woman presented with fever and upper abdominal pain. Abdominal computed tomography and magnetic resonance imaging revealed a 95 × 80‐mm left adrenal cyst. As malignant disease could not be ruled out, and the patient was symptomatic, we opted for robot‐assisted left adrenalectomy. The pathological findings indicated an adrenal pseudocyst.ConclusionsThis is the second report of the successful robot‐assisted removal of a giant adrenal cyst.
Conflict and small‐scale investment: Evidence from Colombian peace agreement
Authors: Nino Gustavo , Baylis Kathy , Crost Benjamin 
Published: January 2023

AbstractThe long‐run effects of conflict on agricultural production depend crucially on how conflict affects farm investment. We use the Colombian peace agreement to estimate how the reduction of violent conflict affects farmer investment decisions. In areas where the armed group was initially present, the end of conflict led to a more than twofold increase in farm investment, as farmers moved production from annual to perennial crops. We find no evidence that investment came at the expense of short‐term consumption, and was likely financed by debt. Our results suggest that decreased investment may be an important mechanism through which armed conflict inhibits agricultural development and points to a potentially large peace dividend.

AbstractGrape seeds are the main byproduct of the grape‐processing industry and contain oil with a high content of high‐quality compounds. In this sense, grape seed oil extracted using Soxhlet, pressing and ultrasound was evaluated in relation to its physicochemical properties, fatty acid composition, antioxidant capacity, degree of unsaturation and critical properties. Interesting values of antioxidant capacity by oxygen radical absorbance capacity assay were obtained for lipophilic and hydrophilic extracts (ca 24–67 and ca 2–7 μmol ET g−1 of oil, respectively). The composition of the grape seed oil varied with the methods of extraction, as expected, with a higher content of linoleic acid in the extraction by pressing due to the absence of the temperature effect in the process. The bis‐allylic position and oxidizability indexes were high for pressing, Soxhlet and ultrasound extraction. Grape seed oil content extracted from Cabernet Sauvignon and Ives species ranged from ca 7% to ca 18% with highest concentrations of saturated, mono‐ and polyunsaturated fatty acids of 187, 124 and 698 mg per gram of oil, respectively, and the highest oil content obtained in the ultrasound‐assisted extraction was under conditions of 50 °C, 60 min and solvent‐to‐seed ratio of 1:8. © 2023 Society of Chemical Industry (SCI).

Authors: Acharya Sneha , Kishore Nanda 
Published: January 2023

AbstractBACKGROUNDLiquefaction of biomass has an advantage over other thermochemical processes of conversion and its co‐liquefaction aims to overcome the restrictions and limitations imposed upon single feedstock liquefaction. Valorization of Citrus limetta peel and pulp wastes by their co‐liquefaction in a hydrogen‐donor solvent such as methanol was chosen as an objective herein for efficient conversion of raw materials to obtain better quality biocrude.RESULTSA maximum biocrude yield of 11.25 wt. % was obtained from solvothermal co‐liquefaction of Citrus limetta peel and pulp biomasses at 260 °C temperature, with 30 min residence time, at three different ratios of biomass to solvent (1:2, 1:3 and 1:4). This was higher than the biocrude yield from liquefaction of individual C. limetta pulp biomass as well as other studies on similar citrus fruit wastes. The higher heating value (HHV) of biocrude was raised to 25.72 MJ kg−1 at 1:3 biomass:solvent ratio by co‐liquefaction, showing its synergy over individual C. limetta peel biocrude. The presence of esters, ketones, alcohols, hydrocarbons and fatty acids in the biocrude product were found from Gas Chromatography–Mass Spectrometry (GC–MS) results. The biochar obtained was mesoporous in nature and could be employed for adsorption in bioremediation of water and soil.CONCLUSIONCo‐liquefaction of homogeneous lignocellulosic biomasses have the ability to boost production and the quality of the biocrude and biochar attained in comparison to products of individual liquefaction. Future studies on upgrading the quality of products are required. © 2023 Society of Chemical Industry (SCI).

Published: January 2023

AbstractBronchial asthma often causes cognitive impairment, especially attentional deficit, which has a serious impact on children's learning. This study aims to provide objective indicators for the evaluation of attention in asthma children. Thirty‐one asthmatic and typically developing children (TDC) were tested by resting‐state functional magnetic resonance imaging (rs‐fMRI). Brain network‐based methods of degree centricity and voxel‐mirrored homotopic connectivity (VMHC) methods were used in the study. Compared with the TDC group, asthmatic children had lower DC values in the right superior frontal gyrus (after FDR correction, P < 0.05). Meanwhile, VMHC values of bilateral superior frontal gyrus and bilateral superior parietal lobule in asthmatic children were lower than those in TDC group (after FDR correction, P < 0.05). There was significant correlation between the correct percentage of CPT and DC value in right superior frontal gyrus, VMHC value in right superior frontal gyrus, and right superior parietal lobule. In this study, impaired superior frontal gyrus and parietal lobe function are associated with attentional deficit in asthmatic children, and these brain regions are key brain regions in attention‐related networks.

AbstractBackgroundCirculating levels of interleukin‐17 (IL‐17) are associated with the presence and severity of periodontitis. However, whether IL‐17 is causal for disease development is unknown. We investigated the effect of genetically proxied IL‐17 on periodontitis using instrumental variable analysis.MethodsWe identified 12 genetic variants from genome‐wide association study (GWAS) of 7760 European descent individuals, used these variants as instrumental variables for IL‐17, and linked them to a GWAS of 17,353 clinical periodontitis cases and 28,210 European controls. Generalized weighted least squares analysis accounted for linkage disequilibrium of variants.ResultsWe found an inverse association of genetically proxied IL‐17 and periodontitis (odds ratio, 0.84; 95% confidence interval: 0.75‒0.94; p = 0.003), which was corroborated after sensitivity analysis for horizontal pleiotropy.ConclusionThe findings suggest that IL‐17 protects against initial periodontitis.
Surface‐Attached Polymer Networks Made from Cationic Poly(diitaconates): Synthesis, Surface Characterization, and Bioactivity

Published: January 2023

AbstractFacially amphiphilic polymers carrying cationic and hydrophobic groups on the same repeat unit have shown promising antimicrobial activity and biocompatibility, yet they are prone to suffer from protein adhesion which may induce biofilm formation. To overcome this problem, poly(diitaconate)‐based copolymers with cationic/hydrophobic and protein‐repellent/charge‐neutral repeat units are synthesized. The bioactivity profile of surface‐attached polymer networks made from these copolymers depends on the ratio of the cationic and charge‐neutral repeat units. In all cases, the protein adhesion is substantially reduced compared to purely cationic polymers. At a 50:50 ratio, the polymer coatings are partially protein‐repellent and antimicrobial, yet slightly cell toxic. At an intermediate composition of 30:70, they are still antimicrobial and the cell compatibility is substantially improved. The long‐term stability of these materials still has to be determined to judge their suitability for medical applications.

AbstractWe investigate in the article the L2‐norm state constrained control problem with first bi‐harmonic equation. First, the optimality conditions of the control problem are derived carefully, and spectral discretization of the problem is established. Based on the property of projection operator, we establish a priori error analysis for control variable, state, and adjoint state variable. Furthermore, the efficient projected gradient algorithm is proposed, and the numerical results we obtained verify the analytical results that it can provide high order accuracy and fast convergence rate.
