Investigation of the effect of spirally stacked fiber reinforcement on the torsional behavior of a polymer composite rod by AE analysis
Authors: M Prakash , Lakshmankumar Abburi 
Published: May 2023

Abstract
The fiber orientation of composite materials has a major impact on the mechanical properties, especially the torsional ability of polymer composites. Automobile and aerospace industries are continually on the search for better polymer composite materials to replace rotating metal components. In this research work, spirally stacked basalt and glass fiber polymer composite solid rods are fabricated by Vacuum Assisted Resin Transfer Molding (VARTM) method to study the torsional behavior under static torsional loading conditions. In order to predict the different failure initiation in the composite materials like matrix cracking, de-bonding and fiber fracture, the Acoustic emission sensor and its signal analysis are used. Time domain, Frequency domain (Fast Fourier Transformation) and Discrete Wavelet Pocket Transformation methods are used to identify the approximate signal levels for different material failure modes. ‘k’-means cluster analysis is also carried out to identify frequency spectrum related to the various failure mechanisms. The observed frequency ranges for different failures are 0 to 100 kHz for matrix failure, 100 to 240 kHz for debonding and 240 to 500 kHz for fiber fractures. The time domain and FFT analysis results are observed to agree with the k-means clustering results and with fractrography of the tested samples.

Abstract
Background: In 2018, the Dutch government initiated the Solid Start program to invest in the first thousand days of life. A central element of the program is improving collaboration between the medical and social sector by creating Solid Start coalitions. This mixed-methods study aimed to describe the implementation of the Dutch Solid Start program, in order to learn for future practice and policy. Specifically, this paper describes to what extent Solid Start is implemented within municipalities and outlines stakeholders’ experiences with the implementation of Solid Start and the associated cross-sectoral collaboration.Methods: Quantitative and qualitative data were collected from 2019 until 2021. Questionnaires were sent to all 352 Dutch municipalities. Qualitative data were obtained through focus group discussions(n = 6) and semi-structured interviews(n = 19) with representatives of care and support organizations, knowledge institutes and professional associations, Solid Start project leaders, advisors, municipal officials, researchers, clients and experts-by-experience. Qualitative data were analyzed using the Rainbow Model of Integrated Care.Results: Findings indicated progress in the development of Solid Start coalitions(n = 40 in 2019, n = 140 in 2021), and an increase in cross-sectoral collaboration. According to the stakeholders, initiating Solid Start increased the sense of urgency concerning the importance of the first thousand days and stimulated professionals from various backgrounds to get to know each other, resulting in more collaborative agreements on cross-sectoral care provision. Important elements mentioned for effective collaboration within coalitions were an active coordinator as driving force, and a shared societal goal. However, stakeholders experienced that Solid Start is not yet fully integrated into all professionals’ everyday practice. Most common barriers for collaboration related to systemic integration at macro-level, including limited resources and collaboration-inhibiting regulations. Stakeholders emphasized the importance of ensuring Solid Start and mentioned various needs, including sustainable funding, supportive regulations, responsiveness to stakeholders’ needs, ongoing knowledge development, and client involvement.Conclusion: Solid Start, as a national program with strong local focus, has led to various incremental changes that supported cross-sectoral collaboration to improve care during the first thousand days, without major transformations of systemic structures. However, to ensure the program’s sustainability, needs such as sustainable funding should be addressed.

Abstract
To effectively address the challenges posed by the increasing share of the energy sector in global greenhouse effects, the domains of energy informatics and energy citizenship are of prime importance. Energy informatics aims at using information systems and channels to reduce energy consumption. However, there is a realization that the challenges posed by global greenhouse effects cannot be catered to alone by the energy information systems. Therefore, there is a need for engaging human inhabitants to actively engage toward more sustainable means (i.e., energy citizenship) thus reducing the energy sector’s share in the global greenhouse effect. This paper presents a systematic literature review (SLR) after analysis of (n = 115) articles on the topic to identify (i) the themes considered in energy informatics and energy citizenship domains, and (ii) the interconnection between energy informatics and energy citizenship domains. The paper summarizes the gaps in the state of the art by mentioning the open research questions.

Abstract
The current study was an attempt to measure ambient air quality in term of PM2.5 and associated heavy metals at two different sites near very busy crossing on National Highway with the help of fine particulate dust sampler. The Average mass concentration for PM2.5 was 77.59μg/m3and 72.86μg/m3 at semi-urban and urban sites. From the outcomes it was determined that the influence of PM2.5 concentrations was greater at the Semi-urban than urban site. Concentrations of PM2.5 have been compared with WHO, NAAQS and USEPA standards and was found to be exceeded than prescribed limit. Among analyzed heavy metals, Ca (11.652 µg/m3), showed the highest concentration due to various construction materials, such as cement, brick lime and concrete as well as road dust, accompanied by Al (1.397µg/m3) and Fe (0.973µg/m3). The concentration of metals followed the trend Ca>Al >Fe > K >Pb>Mn> Co > Cr > Cu > Ni and Ca>Al >Fe > K >Mn>Pb> Cr > Ni > Cu > Co at both the sites. The Enrichment factor (EF) values concluded that Al, K, Fe, and Mn as less enriched (EF< 10) while Co and Pb had been classified as very highly enriched (EF>100). Hazard Quotient (HQ) for Al, Cr, Mn, and Ni is lower than the safe level (HQ= 1) whereas Excess Lifetime Cancer Risk (ELCR) of Cr (VI) and Ni exceeded the respective safer limit ELCR≥ 10-6 indicating long-term exposure to particulate-bound toxic metals via inhalation could lead to cancer in approximately one child and four adults per million.

Abstract
Background To investigate the role of combined impulse oscillometry (IOS) and fractional exhaled nitric oxide (FeNO) in the diagnosis of cough variant asthma (CVA) in preschool children.Methods A total of 197 preschool-aged children with chronic cough were selected from the paediatric outpatient clinic. Allergy histories were collected for all children along with IOS and FeNO. Paediatric respiratory specialists divided the children into a CVA group (n = 90) and a noncough variant asthma (nCVA) group (n = 107) according to the diagnostic criteria for CVA After diagnostic treatment, the correlation between the FeNO and IOS values and the diagnosis in the two groups was analysed, and the area under the curve (AUC) of each index was calculated.Results (1) X5 was significantly different between the CVA group and the nCVA group (-4.22 vs -3.64, p < 0.001), as was the FeNO value (29.07 vs 16.64, p < 0.001). (2) Receiver operating characteristic (ROC) analysis showed that the AUCs of FeNO alone and X5 alone were 0.779 and 0.657, respectively, while the AUC of FeNO (cut-off value of 18 ppb) plus X5 (cut-off value of -4.15 cmH2O/(l/s)) reached 0.809.Conclusions Children with CVA may have small airway dysfunction at an early stage. For preschool children with chronic cough, the combination of FeNO and X5 can better identify those with CVA.Trial registration This trial was registered with and approved by the Chinese Clinical Trial Registry, with registration number ChiCTRcRRC-17011738, and was reviewed and approved by the Ethics Committee of Southwest Hospital.

AbstractInformation onper seperformance, heterosis and heterotic grouping of newly developed maize lines is required for successful hybrids development. The study was conducted to assess theper seperformance of inbreds, examine the inbred-hybrid relationship and classify the lines into heterotic groups. Seventy-nine inbreds developed at Institute for Agricultural Research Zaria were crossed to three testers to generate 237 hybrids. The parental lines and hybrids were separately evaluated under low- and optimum-N conditions at Zaria in 2020 and 2021. The results revealed significant differences (ρ < 0.05) among the inbreds and hybrids for grain yield and most measured traits under low- and optimum-N conditions. Inbred parent SMLW-156 was the highest yielding under low-N and optimum-N condition with average yield advantage of more than 100% and 65% over the best check under low-N and optimum-N condition, respectively. Parental lines SMLW-146 and SMLW-155 were identified as testers. Hybrid SMLW-165 x IITA 1876 had better parent (253.1%) and standard heterosis (48%) for grain yield under optimum-N environment. Hybrid SMLW-105 x IITA 1876 out-yielded standard check by over 100% while SMLW-134 x IITA 1878 was the best for mid and better parent heterosis under low N. Inbreds were classified into four and three distinct groups under low- and optimum-N environments, respectively. Inbred lines within each heterotic group can be recombined to form heterotic populations which can be improved through recurrent selection.

Abstract
The increasing worldwide waste of polymers and agricultural products has prompted a pressing need for biodegradable plastic to help protect the environment. Hence, this research focuses on polybutylene adipate-co-terephthalate (PBAT) biodegradable polymers containing between 30–50 percent of filler to achieve an optimal balance of mechanical properties and biodegradation. Given its high lignin content, rice husk has displayed comparable properties to those of commercial lignin, and thus, the lignin from the rice husk was modified with acrylic acid grafting to facilitate the composite fabrication process. Fourier transform infrared (FTIR) analysis was used to demonstrate the grafting synergy and verify that the lignin/rice husk had been successfully grafted with the acrylic acid grafting process. Subsequently, the acrylic acid grafted lignin/rice husk was incorporated into PBAT to create a PBAT composite containing 30–50% AA lignin. The results revealed that the lignin: PBAT ratio at 30:70 (P70L30) resulted in the most optimum mechanical properties and biodegradability. These included tensile strength of 19.48 MPa, elongation at break of 20.26 MPa, Young’s modulus of 1913.62%, and crystallinity of 31.45%. The biodegradation of P70L30 was 57.36% over the 6 months, which was faster than the 9.2% degradation of PBAT. Additionally, the water absorption of P70L30 was two times more compared to PBAT, indicating the change in hydrophobicity of PBAT to a hydrophilic composite. Agricultural waste-rice husk displayed identical properties to lignin when incorporated into PBAT and resulting in the mechanical properties of strength, elongation at yield, and Young’s modulus of 19.09 MPa, 21.87%, and 1936.98MPa. The mechanical properties and biodegradability of P70L30 on both lignin/rice husk in PBAT composite demonstrated the potential of affordable materials to create sustainable packaging solutions with good biodegradability and added features.

Abstract
The Blursday database is a collection of data obtained online from a longitudinal study where participants were asked to participate in several behavioral tasks and questionnaires during the COVID-19 pandemic from their homes. In this study, we analyzed the published data to explore (1) the longitudinal changes in temporal cognition observed from the data collected in the home-based setting (2), the effects of the voluntary quarantine measures implemented in Japan on temporal cognition, (3) whether the citizen’s temporal cognition is altered by the change in psychological state or the cognitive abilities, and (4) how the effects of the quarantine measures may or may not vary depending on the age of the individual. Results show that confinement measures were good predictors for the performance in both spontaneous finger-tapping task and paced finger-tapping task, though these were dependent on the age of the participant. In addition, cognitive scores were good predictors of the performance in the paced finger-tapping task but not the spontaneous finger-tapping task. Overall, this study provides evidence suggesting changes in both psychological, cognitive, and temporal cognition during the pandemic on the Japanese population despite its voluntary measures to deal with the new situation.
Detecting GNSS spoofing using deep learning

Published: May 2023

Abstract
Global Navigation Satellite System (GNSS) is pervasively used in position, navigation, and timing (PNT) applications. As a consequence, important assets have become vulnerable to intentional attacks on GNSS, where of particular relevance is spoofing transmissions that aim at superseding legitimate signals with forged ones in order to control a receiver’s PNT computations. Detecting such attacks is therefore crucial, and this article proposes to employ an algorithm based on deep learning to achieve the task. A data-driven classifier is considered that has two components: a deep learning model that leverages parallelization to reduce its computational complexity, and a clustering algorithm that estimates the number and parameters of the spoofing signals. Based on the experimental results, it can be concluded that the proposed scheme exhibits superior performance compared to the existing solutions, especially under moderate-to-high signal-to-noise ratios.

Abstract
Background and Purpose
Lack of timely foot care in diabetics result in ulceration followed by infection and amputation. This study aimed to evaluate the foot self-care status and foot screening of patients suffering from diabetes around the country of Iran.
Methods
The cross-sectional descriptive study was performed on patients with type 2 diabetes in 10 main cities of Iran. The information about demographic and lifestyle factors, diabetes history, diabetic foot self-care situation (DFSQ) was assessed. Additionally, the neurological and vascular condition of the foot were screened by Inlow’s 60-Second Screen.
Results
Participants were 1094 diabetic patients. Most of the participants were female (64.8%) and married (92.5%) with the average age of 57.6 ± 10.21 (mean ± SD). The mean duration of DM was 11.56 ± 7.41 years. According to the Inlow’s 60-Second Screen criteria, 58% of patients should have foot ulcer screened yearly and 47% of the patients had peripheral neuropathy, 37% of population had inappropriate foot wear.
Conclusion
Considering the prevalence of peripheral neuropathy among about than half of participants in this study across Iran, it is essential to have continuous patients’ education about foot care and foot wear. Additionally, foot ulcer screening would be performed in recommended interval of Inlow screen.
Impact of low serum iron on treatment outcome of PD-1 inhibitors in advanced gastric cancer
Authors: Yang Yu , Li Ya , Chen Zhendong 
Published: May 2023

Abstract
Background: The aim of this study was toinvestigate the influence of serum iron levels in advanced gastric cancer (GC) patients treated with programmed cell death protein-1 (PD-1) inhibitors.
Methods: We retrospectively reviewed 179 GC patients who were treated with PD-1 inhibitors at our center. Clinicopathological characteristics, laboratory data, and clinical outcomes were analyzed.
Results：Multivariate analysis showed that Eastern Cooperative Oncology Group performance status (ECOG PS), histological subtype, baseline serum iron levels and surgery were independent prognostic factors for overall survival (OS), while ECOG PS, metastatic sites, and treatment lines were independent prognostic factors for progression-free survival (PFS). Patients with baseline low serum iron levels (LSI) had a significantly shorter median OS and PFS compared to patients with normal serum iron levels (NSI)(OS: 8 vs 15 months, p = 0.001; PFS: 4 vs 5 months, p = 0.009). Patients with baseline LSI had a disease control rate (DCR) of 61.2% at 2 months after PD-1inhibitor initiation (M2), compared to 77.8% in patients with NSI (p = 0.024). Patients with baseline LSI had a DCR of 43.2% at 4 months, compared to 60.7% in patients with NSI (p = 0.029).
Conclusions: LSI was associated with worse OS, PFS, and DCR in GC patients treated with PD-1 inhibitors and might be a quick and efficient biomarker to predict the efficacy of PD-1 inhibitors.

Published: May 2023

Abstract
The mission of the National Breast and Cervical Cancer Early Detection Program's (NBCCEDP) mission is to improve access to mammography and other health services for underserved women. Since its inception in 1991, this national program has improved breast cancer screening rates for women who are uninsured and underinsured. However, the literature has shown that NBCCEDP screenings are decreasing, and only reach a portion of eligible women. Reliable estimates at the sub-county level are needed to identify and reach eligible women. Our work builds upon previous estimates by integrating uninsured and insurance status into spatially adaptive filters. We use spatially adaptive filters to create small area estimates of standardized incidence ratios describing the utilization rate of NBCCEDP services in Minnesota. We integrate the American Community Survey (2010–2014) insurance status data to account for the percentage that an individual is uninsured. We test five models that integrate insurance status by age, sex, and race/ethnicity. Our composite model, which adjusts for age, sex, and race/ethnicity insurance statuses, reduces 95% of the estimation error. We estimate that there approximately 49,913.7 women eligible to receive services for Minnesota. We also create small geography (i.e., county and sub-county) estimates for Minnesota. The integration of the insurance data improved our utilization estimate. The development of these methods will allow state programs to more efficiently use their resources and understand their reach.

Published: May 2023

Abstract
In this study, the cellulose pulp was pretreated with a deep eutectic solvent (DES) composed of betaine and anhydrous oxalic acid with a molar ratio of 1:2, and then homogenized to produce amphoteric cellulose nanofibers (CNF). The DES is gentle for the pretreatment of cellulose pulp, but still can effectively solve blockage problem in the homogenization process. Importantly, some carboxyl groups from oxalic acid and quaternary ammonium groups from betaine were introduced onto the surface of cellulose by esterification in this pretreatment process. The CNF shows uniform size distribution, good thixotropy, and high thermal stability. In addition, the crystal structure of CNF maintained cellulose Iβ unchanged and the crystallinity index of CNF is slightly higher than that of bleached softwood kraft pulp (BSKP). Steady rheological analysis and modulus analysis show that all amphoteric CNF suspensions are pseudoplastic fluid with shear-thinning behavior, and have weak fibril network structure but still exhibit solid like behavior under low shear conditions at a concentration of 1.2%. Therefore, an efficient green pretreatment method was developed for preparation of amphoteric CNF which shows a promising application in the field of various fluid materials.
Numerical modeling on wave-current flows and bed shear stresses over an algal reef
Authors: Lan Yi-Ru , Huang Zhi-Cheng 
Published: May 2023

Abstract
Numerical modeling on the depth-averaged currents and bed shear stresses over an algal reef was performed using a coupled wave-current model (Delft-3D). The modeled results were validated and compared to the field observed data, and two numerical cases with and without wind forcing were tested. Oceanographic and meteorological conditions on the shallow reef were wind speed of up to 12 m/s, significant wave height of up to 2 m, water depth of 3 m, and current speed within 0.4 m/s. The model considers hydrodynamic forcing in terms of tides, waves, wind stresses, and bed friction; the depth-averaged currents and bed shear stresses are generally well reproduced by the model. We found that tide is the primary factor driving the current in shallow waters; however, the currents are also significantly affected by wind speeds and the directions between the wind and currents during the high wind events. Two models were chosen to study the bed shear stress induced by wave-current nonlinear interaction and to test the nonlinear enhancement of bed shear stress by waves. Compared to the observed data, we found a significant difference between the two models in predicting bed shear stresses. The results highlight a critical role of the nonlinear interaction between waves and currents in predicting the bed shear stresses during conditions of high wave orbital motions; improvement of the present wave-current nonlinear interaction model for predicting the bed shear stresses may be needed.
