SINDy-SA: Enhancing Nonlinear System Identification with Sensitivity Analysis
Authors: Naozuka Gustavo T. , Rocha Heber L. , Silva Renato S. , Almeida Regina C. 
Published: February 2022

Abstract
Machine learning methods have revolutionized studies in several areas of knowledge, helping to understand and extract information from experimental data. Recently, these data-driven methods have also been used to discover structures of mathematical models. The sparse identification of nonlinear dynamics (SINDy) method has been proposed with the aim of identifying nonlinear dynamical systems, assuming that the equations have only a few important terms that govern the dynamics. By defining a library of possible terms, the SINDy approach solves a sparse regression problem by eliminating terms whose coefficients are smaller than a threshold. However, the choice of this threshold is decisive for the correct identification of the model structure. In this work, we build on the SINDy method by integrating it with a global sensitivity analysis (SA) technique that allows to classify terms according to their importance in relation to the desired quantity of interest. The proposed SINDy-SA approach thus eliminates the need to define the SINDy threshold. We compare our method with the original SINDy approach employing them in a variety of applications whose simulated data have different behaviors. For each application, we formulate different experimental settings and select the best model for both methods using model selection techniques based on information criteria. The results demonstrate that the SINDy-SA framework is a promising methodology to accurately identify interpretable data-driven models.

Published: February 2022

Abstract
Female moths emit sex pheromone to attracts males, and although they are not attracted to their own sex pheromone, they appear to detect it because it affects their behavior. In order to elucidate the mechanism of pheromone "autodetection" we compared responses of olfactory receptor neurons (ORNs) of male and female Grapholita molesta, a species with reported pheromone autodetection. Two concentrations of the major (Z8-12:Ac) and minor (E8-12:Ac) sex pheromone components, a plant-volatile blend containing methyl salicylate, terpinyl acetate and (E)-β-farnesene, and the male-produced hair-pencil (i.e., courtship) pheromone (ethyl trans-cinnamate) were tested in 45 male and 305 female ORNs. Hierarchical cluster analysis showed radically different peripheral olfactory systems between sexes that could be linked to their specific ecological roles. In males 63% of the ORNs were tuned specifically to the major and minor female sex pheromone components, and 4% to the plant volatile blend, while the remaining 33% showed unspecific responses. In females 3% of the ORNs were specifically tuned to the male hair-pencil pheromone, 6% to the plant volatile blend, 91% were unspecific, and no ORN was tuned their own sex pheromone components. The lack of sex pheromone-specific ORNs in females suggests that they are not able to discriminate pheromone blends, and thus pheromone autodetection is unlikely in this species.

Abstract

Background: From March – June 2021, the third wave of the COVID-19 pandemic occurred in Germany. First and second wave evaluations showed an increase in mental health problems and a reduction of quality of life in adolescents. In August 2021, two vaccines against COVID-19 were approved for adolescents aged 12-17 years in Germany. Aim of the study was to assess mental health and health-related quality of life (HRQoL) after 1.5 years of COVID-19 pandemic in adolescents who decided to receive a vaccination. Methods: In the German region of Siegen-Wittgenstein, all students from 12-17 years from secondary level schools, vocational schools and universities were offered a prioritized vaccination against COVID-19. Mental health and HRQoL were assessed at the first vaccination appointment by self- and parental report. Adolescents and their parents completed the Strength and Difficulties Questionnaire (SDQ) and the KIDSCREEN-10. Results: Data from 1412 adolescents (49.2% female, 47.7% male; mean age 14.3 years, SD=1.64) and 908 parents were collected. Mean self-reported HRQoL was T=53.7 (SD=11.2), in boys significantly higher than in girls (56.0 vs. 51.3), and significantly higher in younger (12-14 years) than in older (15-17 years) adolescents (56.2 vs. 51.5). Parental-reported HRQoL was T=51.8 (SD=12.8). In total, 18.5% of adolescents reported clinically relevant psychological symptoms, especially peer problems (23.7%), emotional problems (16.7%) and hyperactivity (17.2%). Girls reported significantly higher scores on emotional, peer and total problems than boys, whereas younger adolescents reported more hyperactivity and less emotional and peer problems than older ones. Comparing the present data to evaluations after the first and second wave of COVID-19 in Germany, adolescents facing vaccination after the third wave rated a higher HRQoL and reported less mental health problems. The data from the present study are comparable to those from pre-COVID evaluations. Conclusion: After 1.5 years of living with the pandemic, adolescents may have adapted to the changes in everyday life which has lowered the anticipated stress. Further, the relaxation of restrictions, better school organization and the prospect of the vaccination may have increased optimism, wellbeing and contentment, leading to declining but still alarming rates of psychological symptoms.

Abstract
This paper presents the characteristics and trends of microplastic pollution in the estuarine ecosystem at Sungai Laloh, Pasir Putih. The sample collected were green mussels and sediment located at two different sampling point. A comparison of similar total weight was made for wild mussel and cultured mussel. The method involved the pre-treatment of green mussels and sediment sample, followed by digestion and analysis. In pre-treatment, the aquatic specimen and sediment undergo non-toxic density separation with the used of 1.2 kg/L sodium chloride (NaCl). The digestion was made by adding 35% (v/v) hydrogen peroxide (H2O2) and incubated for 24 to 48 hours by using incubator shaker at of 50℃ and 80 rpm. Analysis was conducted by using stereomicroscope and Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR FT-IR). In addition, SPSS statistical software was used to determine the significant difference between wild mussel and cultured mussel. Results show that microplastic fragment found abundant in mussel while microplastic fibers were found in sediment. The types of polymer microplastic found were polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), ethylene vinyl acetate (EVA) and nylon (all polyamides). In comparison based on percentage of abundance, cultured mussel was the most polluted with microplastic.

Abstract
BACKGROUND: Overweight and obesity are highly prevalent conditions associated with premature morbidity and mortality worldwide. Capsiate, a nonpungent analogue of capsaicin, binds to capsaicin binds to TRP vanilloid 1 (TRPV1) receptor, which is involved in adipogenesis, and could be effective as a weight-lowering agent. METHODS AND RESULTS: Eighteen slightly overweight women were enrolled in this randomized, doble-blind, placebo-controlled study. Nine patients were included in the capsiate intervention group and received 9 mg/day of capsinoids whereas other 9 patients received placebo for 8 weeks. All patients underwent weight and waist circumference assessment before and after treatment. Body composition and bone mineral density were also detected by Dual-energy X-ray absorptiometry (DXA). Fourteen patients completed the study. The treatment with capsiate or placebo for 8 weeks was not associated to significant changes in weight or waist circumference. After treatment, there was a significant improvement of Bone Mineral density (BMD values measured at the spine in the capsiate group (1.158 vs 1.106 g/cm2, +4.7%; p = 0.04), but not in the group treated with placebo. Similarly, the capsiate group showed a 9.1% increase (p = 0.05) in the adipose tissue and an 8.5% decrease in lean mass measured at the supraclavicular level, whereas these changes were not statistically significant in the placebo group.CONCLUSION: Treatment with capsiate for 8 weeks led to negligible changes in body weight in a small sample of slightly overweight women, but our findings suggest a potential effect of capsaicin on bone metabolism in humans.

Abstract
Looming concerns regarding scarcity, high prices and safety threatens the long-term use of lithium in energy storage devices. Calcium has been explored in batteries because of its abundance and low-cost, but the larger size and higher charge density of calcium-ions relative to lithium impairs diffusion kinetics and cyclic stability. In this work, an aqueous calcium-ion battery is demonstrated using orthorhombic, trigonal and tetragonal polymorphs of molybdenum vanadium oxide (MoVO) as a host for calcium ions. Orthorhombic and trigonal MoVO outperforms the tetragonal structure because large hexagonal and heptagonal tunnels are ubiquitous in such crystals, providing facile pathways for calcium diffusion. For trigonal MoVO, a specific capacity of ~203 mAh g-1 was obtained at ~0.2C and at 100 times faster rate of ~20C, ~60 mAh g-1 capacity was achieved. The open-tunnel trigonal and orthorhombic polymorphs also promote cyclic stability and reversibility, showing a capacity fade rate of ~0.15% per cycle. A review of the literature indicates that MoVO provides one of the best performances reported to date for the storage of calcium.

Abstract
Background: The aim of this study is to compare the LPP [luteal phase estradiol LPP/GnRH antagonists protocol] treatment of patients with poor ovarian response [POR] in terms of the results of in vitro fertilization [IVF] treatment who underwent LPP in the first IVF treatment or in the use of LPP in the second treatment of patients with a different protocol. Materials and methods: 293 cycles recorded in 226 patients with poor ovarian reserve who underwent LPP treatment, microdose flare-up protocols, and antagonist protocols between 2013 and 2019 were included in the study. Of these, 38 patients received LPP treatment in the first cycle and LPP treatment in the second cycle. After the microdose or antagonist protocols were applied in the first cycle, LPP treatment was applied to 29 patients in the second cycle. There were 128 patients who received LPP only once and 31 patients who received microdose flare-up only once, and these patients were included in the study based on LPP and microdose application results in the patient group with low ovarian response. Results: In our second cycle results of LPP application in patients with low ovarian response that resulted in one failed IVF, the clinical pregnancy rate was higher than the patients who received only LPP and patients who received LPP after different protocols [p=0.035]. In unsuccessful IVF patients who had LPP applied in the first cycle, β-hCG positivity per embryo and clinical pregnancy rates were found to be significantly higher in patients who received the LPP application in the second protocol [p=0.000, p=0.001].Conclusion: Repeated LPP may be the first choice protocol for low ovarian reserve patients.
Self-control and Mental Health? Exploring Perceptions of Control from the Experiences of Black and Minority Communities
Authors: Joseph Stephen , Keating Frank 
Published: February 2022

Although the disparities in mental health outcomes for ethnic minorities are well-documented, very little is known regarding service user perspectives and experiences from locus of control ambit. The aim of this qualitative study was to investigate the experiences of African and Caribbean service users, from the context of their Locus of Control (LOC). Informed by an Interpretivist approach, this study was conducted via in-depth interviews (N=10) and two focus groups (N=14). Purposive sampling methods were used to recruit mental health service users from a South London Borough to participate in the study. Data was collected through a semi-structured interview schedule and a focus group guide. Data analysis was informed by an Interpretive Phenomenology Analysis approach in the examination of the LOC profiles and service user perspectives. The study found that the drivers of LOC for the respondents were: perceived racism; perceived loss of control due to challenges pertaining to accessing employment, work stressors, lack of career advancement, socio-economic challenges; discrimination at work, identity challenges and entry to and exit pathways from mental health services, all of which promotes LOC externality. The findings suggest that mental health services need to take an active interest in factors that constitute externality in the LOC in assessment of the needs of A & C groups in clinical and community interventions. A holistic approach to psycho-social and socio-cultural issues are highly needed to improve the mental health outcomes for members of African and Caribbean communities with experience of mental health challenges.

This study aimed to get information on the cultivation of sweet pepper from the North West Region of Cameroon (Foumbot). Data for the study were obtained from 92 farmers with the aid of well-structured questionnaires. Results obtained showed that among the sweet pepper farmers, males represented 80% of the sampled population and women 12%, all of them aged between 18 to 48 years old. Their level of education varies from primary school to University with the majority found between primary school (48%) and secondary school (30%). 41% of the sampled cultivators have the greatest level of experience in between 10 to 30 years and 52% with the lowest level of experience varying from 1 to 10 years. The sweetest pepper varieties cultivated was Yolo wonder and Simba. 89 % of respondents had a sweet pepper field with a surface area between 0.5 and 1 hectare. According to farmers, the nursery is usually attacked by fungi after one week of growth, which always cause stems rot. Fungicides (Mancostar 80WP) and insecticides (Mocap EC, Timik, Plantineb 80WP, Jumper and Ascot) are the most chemical products used to treat stems rot. Cypermethrin and Mancozeb represent respectively 63% and 85% of active ingredients used by the sampled growers to fight against sweet pepper diseases. 46 % of the sampled farmers said that they prefer spray pesticides in all stages while 44% of sweet pepper farmers did not take note of the number of times, they applied chemicals pesticides on their crops. NPK: 20.10.10 is the most chemical fertilizer used to grow sweet pepper. The major diseases and pests encountered in that region are (1) diseases: Mildew, cercospora leaf spot, phytophthora blight, fusarium wilt, anthracnose, ripe rot, tobacco mosaic virus, cucumber mosaic virus, and gal formations; (2) pests: flee beetles, cutworms, aphids, vegetable weevil, caterpillars, grasshoppers, pepper maggots and leaf miners.

Authors: Denisova V. , Mezule L. , Juhna T. 
Published: February 2022

Abstract
Drinking water disinfection or inactivation of pathogenic microorganisms is an essential step to minimize infection risks and decrease the incidence of waterborne diseases. Recently, chitosan nanoparticles (CNs) have been highlighted as an antimicrobial agent for a wide range of applications due to their natural antimicrobial properties, and low or no toxicity risk for human health. In this study, we generated CNs from three different molecular weight (MW) chitosan (low, medium, high) at various concentrations (0.25, 0.5 and 2% (w/v)). After the CNs preparation and quality assessment, the antimicrobial activity was evaluated by measuring the log reduction of Gram-negative bacteria E. coli as a model microorganism for faecal pollution. The results demonstrated that 0.25% of medium MW CNs are optimal for more than 99.99% reduction of cultivable E. coli and 97% inactivation of metabolically active E. coli. These results indicated that CNs were able to inhibit the growth of cultivable and metabolically active E. coli in tap water and demonstrated the potential use of CNs as an alternative antimicrobial agent in drinking water disinfection.

Published: February 2022

Abstract
In this study, a novel optimization-simulation dynamic approach was developed for optimal water operation of reservoir-river systems to improve the water quality and supply the water demands along a river. To this purpose, the WEAP-QUAL2 K linked model was developed to simulate water quality and quantity, which is dynamically coupled to a fuzzy multi-objective imperialist competition algorithm (FMOICA). The approach's applicability is demonstrated through the case study of the Dez reservoir river in Iran. The simulation and optimization period used was six years (October 2019-September 2025). Stochastic models (SARIMA(1,0,1)(1,1,1)) were used to forecast inflow into the Dez dam reservoir for the simulation period. Given that in the verification stage of the QUAL2 K and WEAP model it was concluded that the model has high accuracy in simulating the parameters of water quality and quantity, two scenarios were considered: the first scenario was used for dynamic coupling of the quantity-quality model (reference scenario), and the second was the fuzzy optimization of a linked model (optimal scenario). The results show that average water supply reliability increased from 86.13% in the reference scenario to 95.76% in the optimal scenario. Also, under the optimal scenario, the river water quality improves. It was also found that environmental flow rate demands of the river are fully supplied in different months.

Background:
Background: Tracing the causes of gene expression variation is helpful to understand tumor evolution and metastasis.

Objective:
Objective: Current gene expression variation explanation methods are confronted with several main challenges: low explanation power, insufficient prediction accuracy, and lack of biological meaning.

Method:
Method: In this study, we propose a novel method to analyze the mRNA expression variations of breast cancers risk genes. Firstly, we collected some high-confidence risk genes related to breast cancer and then designed a rank-based method to preprocess the breast cancers copy number variation (CNV) and mRNA data. Secondly, to elevate the biological meaning and narrow down the combinatorial space, we introduced a prior gene interaction network and applied a network clustering algorithm to generate high density subnetworks. Lastly, to describe the interlinked structure within and between subnetworks and target genes mRNA expression, we proposed a group sparse learning model to identify CNVs for pathogenic genes expression variations.
