Published: September 2022

Abstract
For the first time, a combination of metaheuristic algorithms and machine learning is used for hydrological drought analysis under climate change conditions and applications. The new framework is used by a novel hybrid machine learning model named the least-squares support vector machine-African vulture optimization algorithm (LSSVM-AVOA). The performance of the proposed hybrid algorithm was compared with three algorithms, including artificial neural network (ANN), adaptive neuro-fuzzy inference system (ANFIS), and least squares support vector machines (LSSVM). Using the technique for order of preference by similarity to the ideal solution (TOPSIS) method showed that LSSVM-AVOA with a score of 0.98 could be employed to improve the LSSVM modeling results. Three global climate models (GCM), including ACCESS-ESM1-5 (A1), CanESM5 (C5), and MRI-ESM2-0 (M2) during the historical period 1985–2014 and four scenarios, including SSP126, SSP245, SSP245-cov-fossil (SCF), SSP585 in future from 2021 to 2050 was considered for predicting discharge at Karun basin (Sepid Dasht Sezar, Bakhtiari Tang Pang, Sezar Tang Pang, Taleh Zang and Gotvand stations). Using new hybrid algorithm, the prediction results showed that discharge in most scenarios and stations decreased between − 0.81% and − 7.83% (except Sezar Tang Pang and Gotvand station). The standardized runoff index (SRI) results of hydrological drought analysis showed by the SSP585 scenario it seems that for the next first 10 years, a mild drought period can occur in this basin. Also, in the future period for SSP126 scenario by the first five years in the next 30 years, none drought is predicted.

Abstract
Purpose: Although hypnotic drug use is a known risk factor for falls, few reports have analyzed fall risk associated with individual hypnotic drugs after adjusting for confounding factors. Therefore, it remains unclear whether clinically prescribed benzodiazepine receptor agonist, melatonin receptor agonist, and/or orexin receptor antagonist use is safe in older patients. Here, we aim to assess the influence of various hypnotic drugs on fall risk in older patients admitted to acute care hospitals.
Methods: We investigated the relationship between nocturnal falls and sleeping pill use among 8,044 hospitalized patients aged > 65 years. We used a propensity score matching method to homogenize characteristics of patients with and without nocturnal falls (n = 145 patients in each group) using 24 extracted factors (excluding hypnotic drugs) as covariates.
Results: Our analysis of fall risk for each hypnotic drug revealed that benzodiazepine receptor agonists were the only drugs significantly associated with falls, suggesting that use of the drugs is a risk factor for falls in older adults (p = 0.003). In addition, a multivariate analysis of 24 selected factors, excluding hypnotic drugs, revealed that patients with advanced recurrent malignancies were at greatest risk of experiencing falls (OR: 2.62; 95% CI: 1.23–5.60; p = 0.013).
Conclusion: Benzodiazepine receptor agonists should be avoided in older hospitalized patients since they increase fall risk, with melatonin and orexin receptor antagonists used instead. Particularly, fall risk associated with hypnotic drugs should be considered in patients with advanced recurrent malignancies.
Numerical simulation of Hongchun gully debris flow based on the coupling of LHT model and Pudasaini model
Authors: QIANG ZHANG 
Published: September 2022

Abstract
Numerical simulation is an important means to reproduce debris flow disaster, and a reasonable model can completely reflect the risk and influence area of the whole process from startup to accumulation of debris flow. In this paper, LHT model and Pudasaini model are adopted to realize dynamic whole-process simulation of debris flow. LHT model can reflect the dynamic volume change of shallow landslides under rainfall conditions, and solve the problem of starting location and starting volume of debris flow. The Pudasaini model simulates the volume change of debris flow in the process of movement according to the start-up condition and boundary conditions. The simulation results showed that Hongchun gully was subjected to rainfall on August 12, 2010 solstice and August 14, 2010. The maximum change of landslide volume occurred near 3:00 on the 14th, which was consistent with the actual starting time of debris flow. At the same time, the accuracy of debris flow accumulation volume and area is verified, and the simulation results are excellent. Good simulation results show that the coupling of LHT model and Pudasaini model can completely reproduce the formation process of "8·14" Hongchun gully massive debris flow. It provides an effective simulation method for debris flow formation under rainfall conditions.
Seeing past the tip of your own nose? How outward and self-centred orientations could contribute to closing the green gap despite helplessness

Abstract

The present study explored moderators of the relation between environmental concerns and pro-environmental behaviour that could help to close the green gap. A sample of 500 individuals (250 women) participated in the study. Apart from socio-demographic characteristics, participants answered questions about their environmental concerns and pro-environmental behaviour, collectivism and individualism, time orientation and emotional responses to climate change. Our results corroborate the view that collectivism, future orientation and prosocial tendencies may form a single component of outward orientation, while individualism and immediate orientation form self-centred orientation. Generally, outwardly oriented individuals and those less self-centred reported more pro-environmental behaviour. However, strongly self-centred individuals, even when reporting elevated helplessness, also showed increased involvement in pro-environmental behaviour once their concerns were high. The study contributes to the literature by pointing out that both outward and self-centred orientations have the potential to insulate individuals against the negative effect helplessness may have on pro-environmental behaviour. This could inform strategies that would both prompt individuals already concerned to act and arouse more concern among those who are not yet preoccupied with climate change.
A nonlinear tunable piezoelectric resonant shunt using a bilinear component: theory and experiment
Authors: Shami Zein Alabidin , Thomas Olivier , Giraud-Audine Christophe 
Published: September 2022

Abstract
In this article, we propose a new concept for tuning a resonant piezoelectric shunt absorber thanks to the use of a nonsmooth electronic component. It consists in adding in the resonant shunt circuit a voltage source which is a bilinear function of the voltage across the piezoelectric patch. The main advantage is the ability to change the electrical resonance frequency with the bilinear component gain, enabling a tuning as well as a possible reduction of the required inductance value. Because of the intrinsic nonlinear nature of the bilinear component, a multi-harmonic response is at hand, leading to a nonlinear coupling between the mechanical and electrical modes. Two particular tunings between the electrical and the mechanical resonance frequencies are tested. The first one is one-to-one, for which the electrical resonance is tuned close to the mechanical one. It is proved to be similar to a classical linear resonant shunt, with the additional tuning ability. The second case consists in tuning the electrical circuit at half the mechanical resonance, leading to a two-to-one (2:1) internal resonance. The obtained response is also found to be similar to a classical resonant shunt near the main resonance. In either case, the shunt performances are analytically and numerically studied, leading to optimal values of the design parameters as well as an estimation of the amplitude reduction provided by the shunt. Finally, experimental validation is proposed, targeting the damping of the twisting mode of a hydrofoil structure, in which the bilinear component is realized with a diode.

Abstract

Many controversies exist related to the changes generated by oil palm plantations in the physicochemical properties of the soil, soil biota, and their interactions. Consequently, the present study evaluated the changes in properties of the soil by the effect of the ages the oil palm on the physicochemical parameters of the soil in comparison with pasture plots (as a control) at a several ages of palm trees, the soil sampling was carried out around the oil palm (at 3, 5, and 15 years old) at distances of 1-, 2-, and 3-m from the trunk plant in a random sampling. The soil properties evaluated were soil pH, cation exchange capacity, bulk density, organic matter, total nitrogen, and minerals such as sulfur, phosphorus, calcium, magnesium, potassium, iron, copper, manganese, zinc, and boron as total minerals were measured. The results showed that both the diameter and the fresh and dry root biomass increased in 15-year-old plantations compared with 3- and 5-year-old. In addition, correlation analysis and principal component analysis indicated that the parameters evaluated are associated with the adult age of the oil palm. Also, the results of soil physicochemical showed that low soil fertility was associated with an increase in the age of the palm.

Abstract
Purpose
New federal legislation in the United States grants patients expanded access to their medical records, making it critical that medical records information is understandable to patients. Provision of informational summaries significantly increase patient perceptions of patient-centered care and reduce feelings of uncertainty, yet their use for cancer pathology is limited.
Methods
Our team developed and piloted patient-centered versions of pathology reports (PCPRs) for four cancer organ sites: prostate, bladder, breast, and colorectal polyp. The objective of this analysis was to identify common barriers and facilitators to support dissemination of PCPRs in care delivery settings. We analyzed quantitative and qualitative data from pilot PCPR implementations, guided by the RE-AIM framework to explore constructs of reach, effectiveness, adoption, implementation, and maintenance.
Results
We present two case studies of PCPR implementation – breast cancer and colorectal polyps — that showcase diverse workflows for pathology reporting. Cross-pilot learnings emphasize the potential for PCPRs to improve patient satisfaction, knowledge, quality of shared decision-making activities, yet several barriers to dissemination exist.
Conclusion
While there is promise in expanding patient-centered cancer communication tools, more work is needed to expand the technological capacity for PCPRs and connect PCPRs to opportunities to reduce costs, improve quality, and reduce waste in care delivery systems.

Abstract
The low-frequency (terahertz) vibrational spectroscopy of two chlorophyll species, Chl-𝑎 and one of its magnesium derivatives (Chl-Mg-Na), has been investigated experimentally. The combination of terahertz time-domain spectroscopy and Fourier transform infrared spectroscopy has enabled a broad frequency range to be covered (0.2 to 18 THz). For Chl-Mg-Na, the terahertz spectra show clear and well-marked features at 1.44, 1.64, and 1.83 THz dominated by intermolecular interactions. The frequency dependent refractive index and absorption coefficient of Chl-Mg-Na were determined using the Fit@TDS software. Below 1.0 THz, a refractive index of 2.09 was measured. In order to acquire further understanding of the observed vibrational modes, a detailed study of the temperature dependence of the line positions of the lowest modes in Chl-Mg-Na was performed. As the temperature is increased from 88 K to 298 K, the feature at 1.83 THz experiences a notable red shift of frequency and line shape broadening, whereas the feature at 1.44 THz shows little change. These results suggest that the 1.83 THz feature is dominated by intermolecular motions occurring over the crystalline unit cell of the Chl-Mg-Na molecular crystal. Finally, terahertz time-domain was used to acquire the spectra of an ornamental plant bearing yellow-green variegated leaves (ivy, Aureomarginata variety), the yellow sectors having lower chlorophyll content compared to green sectors. In dehydrated green tissue, the chlorophyll molecules showed well-marked intermolecular vibrational modes at 1.85 THz, indicating that chlorophyll molecules are prone to pack with an ordered molecular arrangement. These results demonstrate the potential application of THz spectroscopy in agricultural sciences.

Published: September 2022

Abstract

Background
Pregnancy complications and unsafe abortions are the leading causes of death among adolescent girls aged 15-19 years globally. Contraceptives have been proven to help prevent unwanted pregnancies, early pregnancies, as well as unsafe abortions. However, contraceptive use remains low, particularly in the least developed countries, including sub-Saharan Africa and Zambia specifically, thereby undermining the potential benefits of contraceptive use. This study sought to explore and understand the motivators and influencers of adolescent girls’ decision-making regarding contraceptive use.
Methods
We used thematic analysis to analyse qualitative data from 7 focus group discussions and 3 key informant interviews aged between 15-19 years in Chongwe, Lusaka, Kasama and Luwingu districts located in Lusaka and Northern provinces, respectively. NVivo version 12 pro (QSR International) was used to manage and organise the data.
Results
Fear of pregnancy, fear of diseases, fear of having more children, and spacing of children (especially among married adolescents), were key motivators for adolescents’ contraceptive use. Friends and peers also motivated them to use contraceptives. None-use was motivated by fear of side effects, and fear of infertility. Peer pressure and fear of mocking by their friends were important deterrents to contraceptive use. Parents, peers and friends, family members, partners, churches, and religious groups influenced adolescent girls’ contraceptive decisions.
Conclusion
Mixed messages from friends, family members, partners, churches and religious groups, some in favour and others against contraceptives, make adolescents’ decisions to use contraceptives complex. Therefore, it is vital to take an all-inclusive approach in developing interventions by incorporating the various influencers, including at institutional and policy levels, even as we seek to empower adolescents and give them autonomy to make contraceptive decisions.

Published: September 2022

Abstract

Multi-roller flow forming has the characteristics of multi-directional loading, which can improve the quality and accuracy of spun products. Roller number and parameter arrangement in a roller set will affect the material flow and rib filling in multi-roller flow forming of cylinder with inner ribs. Therefore, in this paper, a finite element model of multi-roller flow forming was established to explore the effects of roller number and parameter arrangement on the material flow and saturation degree of inner ribs of aluminium cylinder with oblique cross ribs. The results show that increasing roller number can promote the material radial flow, leading to improve the saturation degree of inner rib; and that, in a roller set, applying large radius for the front roller and small radius for the subsequent roller is beneficial to rib filling, and the more radial offset amount of the first roller has, the more sufficient material flow into the inner ribs is under constant total thickness reduction. In addition, an aluminum cylinder with cross ribs had been spun successfully, which had good dimensional accuracy and mechanical properties. The approaches can provide process guidance for manufacturing on flow forming of aluminum cylinder with inner ribs.

Published: September 2022

AbstractBackground 3-Nitropropionic acid (3-NP) is strongly believed to be a mitochondrial complex II irreversible inhibitor, leading to neural damages. Silymarin has been reported to exert various pharmacological manifestations including hepatoprotection, anti-inflammatory, anti-oxidant and cardioprotection. This study aimed to investigate neuroprotective features of silymarin against 3-Nitropropionic acid-induced neurotoxicity in male mice. Methods Six-week-old mice were received sub-chronic doses of 3-NP, intraperitoneally for 17 days. A group of mice were pretreated with silymarin (70 mg/kg/day, P.O.) for two weeks before 3-NP administration. Treatment group was received 3-NP for 17 days and then silymarin (70 mg/kg/day, P.O.) for 4weeks. At the end of the treatment schedule, animals were evaluated for behavioral alterations. Afterward, mice were sacrificed, neuronal damages in the hippocampus region of the brain tissues were performed by H&E staining, and the homogenates brain was used for evaluating the oxidative stress related parameters (Lipid peroxidation, nitric oxide, superoxide dismutase, glutathione, and total antioxidant capacity) and pro-inflammatory cytokine (TNF-α, IL-17, and IL-1β) levels. Results Our results indicated that 3-NP treatment significantly (p < 0.05) tends to reduce the motor coordination, memory, and neuronal antioxidant status while increased the pro-inflammatory cytokine levels. However, silymarin in both treatment and pretreatment protocols markedly (p < 0.05) attenuated the behavioral deficits, oxidative stress status, and neuroinflammation. Conclusion Results of the current study suggested that neuroprotective effect of silymarin against 3-NP-induced neurotoxicity might be due to mitigating oxidative stress status and provide insight into the therapeutic potential of silymarin.

Published: September 2022

Abstract
Bacterial cellulose (BC) is an unbranched biopolymer produced by microorganisms, composed of glucopyranose units linked by β-1,4 bonds. In this study, the adjuvant action of needle shaped BC micro fibrils (BCmfs) has been investigated in vitro using bovine serum albumin (BSA) as a model antigen. BC produced by the static culture of Komagataibacter xylinus was then microparticleated (1–5 µm) by acid hydrolysis and characterized using Zetasizer and scanning electron microscopy (SEM). Subsequently, cytotoxicity, TNF-α (Tumor necrosis factor alpha) and IL-6 (Interleukin-6) cytokine secretion, and cellular uptake of BCmfs-BSA conjugate on the human monocyte cell line (U937) differentiated into macrophages were performed. In the cytotoxicity assay, BCmfs-BSA in macrophage cells showed high viability (over 70%). The highest TNF-α cytokine level (113 ng/ml) was obtained with BCmfs-BSA (Bovine serum albumin) conjugate (500µg/ml) and was statistically significant (p = 0.0001) compared to the positive control group (BSA-aluminum hydroxide), IL-6 cytokine levels were not statistically different from those in the control group as desired. It has been shown in macrophage-differentiated U937 cells that microbial synthesized BC in the form of needle-shaped micro fibrils (BCmfs) has high cellular uptake capacity and increases the immunogenicity of the antigen. These results demonstrate for the first time that BC micro fibrils have the potential to serve as a vaccine adjuvant.

Abstract
Purpose: A diagnostic and treatment strategy for appendiceal tumors (ATs) has not been established. We aimed to evaluate our treatment strategy for ATs including laparoscopic surgery (LS) and to identify preoperative malignancy predictors.
Methods: A total of 51 patients were retrospectively reviewed. Data including tumor markers and imaging findings were compared between carcinoma and non-carcinoma patients. Validity of planned operation was evaluated based on pathological diagnosis.
Results: Twenty-five patients were diagnosed with carcinoma, 13 with low-grade mucinous neoplasm, and 13 with other diseases. Symptoms were more commonly present in carcinoma patients than in non-carcinoma patients (68.0% vs. 23.1%, p=0.001). Elevated CEA and CA19-9 were more frequently observed in carcinoma patients than in non-carcinoma patients (p<0.01 and p=0.04, respectively). Five carcinoma patients had malignancy on biopsy, compared with zero non-carcinoma patients. Significant differences were noted in the percentages of carcinoma and non-carcinoma patients with solid enhanced mass (41.7% vs. 0%, p<0.001) and tumor wall irregularity (16.7% vs. 0%, p=0.03) on imaging. Although the sensitivity was not high, the specificity and positive predictive value of these findings were 100%. Forty-two patients (82.4%) underwent LS as minimally invasive exploratory tool and/or radical operation, of whom 2 were converted to open surgery for invasion of adjacent organ. None of the patients had intraoperative complications or postoperative mortality.
Conclusion: Clinical symptoms, elevated tumor markers, and worrisome features of solid enhanced mass and tumor wall irregularity on imaging can be malignancy predictors. For management of AT patients, LS is feasible and useful for diagnosis and treatment.
