Authors: Jain Seema , Higashi Robin T. , Salmeron Carolina , Bhavan Kavita 
Published: October 2022

Abstract
Background
Lack of childcare has been linked to missed healthcare appointments, especially among lower-income women. The COVID-19 pandemic created additional stressors for many low-income families that already struggled to meet childcare and healthcare needs, impacting women’s health and daily life experiences in unknown ways. By exploring the experiences of women who were referred for childcare services at a US safety-net health system, we aimed to understand the challenges women faced in managing their health and childcare needs during the COVID-19 pandemic.
Methods
We conducted semi-structured interviews with participants in Dallas County, TX between August 2021 and February 2022. All participants were referred from the county’s safety-net hospital system’s women’s health clinics to an on-site drop-off childcare center by staff who identified lack of childcare as a barrier to accessing healthcare. Participants were the primary caregiver for at least 1 child ≤ 13 years. Interviews were conducted in English or Spanish. We analyzed data using thematic content analysis.
Results
We interviewed 22 female participants (mean age 34 years); participants had on average 3 children and primarily identified as Hispanic or African American. Three interrelated themes emerged from the data: disruptions in access to healthcare, the inextricable link between childcare and health, and emotional distress.
Conclusions
Our findings emphasize the intersectionality of family and social context with a patient’s health and add to our understanding of childcare as a social need.

Abstract

Objective:To better understand the relationship among cell adhesion molecules (CAM) and investigate the clinical diagnostic and prognostic application of ICAM-1 (ICAM1), LFA-1 (ITGAL), and L-selectin (SELL) proteins and mRNA corresponding expression in thyroid cancer.Design andMethods:Gene expression was evaluated by RT–qPCR, and protein expression was evaluated by immunohistochemistry. We evaluated 275 patients (218 women, 57 men, 48.4±14.5 years old), including 102 benign and 173 malignant nodules. The 143 papillary thyroid carcinoma (PTC) and 30 follicular thyroid carcinoma (FTC) patients were managed according to current guidelines and followed-up for 78.7±54.2 months.Results:Malignant and benign nodules differed concerning mRNA (p=0.0027) and protein (p=0.0020 for nuclear) expression of L-selectin and ICAM-1 (mRNA: p=0.0001 and protein: p=0.0014) and protein expression of LFA-1 (p=0.0168), but not mRNA expression of LFA-1 (p=0.2131).SELLexpression was more intense in malignant tumors (p=0.0027).ICAM1(p=0.0064) andITGAL(p=0.0244) mRNA expression was higher in tumors with lymphocyte infiltrate. ICAM-1 expression correlated with younger age at diagnosis (p=0.0312) and smaller tumor size (p=0.0443). Also, LFA-1 expression correlated with higher age at diagnosis (p=0.0376) and was more intense at stage III and IV(p=0.0077).Conclusion:In general, the protein expression of the 3 CAM decreased as the process of cellular dedifferentiation occurred. We suggest that theSELLandICAM1genesand L-selectin and LFA-1 protein expression may help confirm malignancy and assist in the histological characterization of follicular patterned lesions, but we were unable to correlate these CAMs with patient outcomes.

Published: October 2022

Abstract
The detection of chemiluminescence from various radicals and molecules in a hydrocarbon flame can provide valuable information on the rate of local heat release, combustion stability, and combustion completeness. In this study, chemiluminescence from the combustion process is detected using a high-speed color camera within the broadband spectrum of visible light. Whereon, a novel hyperspectral reconstruction approach based on the physically plausible spectral reconstruction (PPSR) is employed to reconstruct the spectral chemiluminescence signals from 400 to 700 nm with a resolution of 10nm to provide 31 different spectral channels. The reconstructed key chemiluminescence signals (e.g., CH*, CH2O*, C2*, and CO2*) from the color images are further analyzed to characterize the chemical kinetics and combustion processes under engine conditions. The spectral chemiluminescence evolution with engine crank angle is identified to comprehend the effect of H2 fraction on flame characteristics and combustion kinetics. Additionally, in this study, a detailed kinetic mechanism is adopted to deepen the theoretical understanding and describe the spectral chemiluminescence from H2/CH4 and H2/CH4/n-dodecane flames at relevant conditions for various species including OH*, CH*, C2*, and CO2*. The results indicate that the PPSR is an adequately reliable approach to reconstructing spectral wavelengths based on chemiluminescence signals from the color images, which can potentially provide qualitative information about the evolution of various species during combustion. Here, the reconstructed chemiluminescence images show less than 1% errors compared to the raw images in red, green, and blue channels. Furthermore, the reconstructed chemiluminescence trends of CH*, CH2O*, C2*, and CO2* show a good agreement with the detailed kinetics 0D simulation.

Abstract
Purpose
Contralateral hematoma progression (CHP) is a common condition among bilateral chronic subdural hematoma (bCSDH) patients after the unilateral evacuation. Investigations focusing on this topic are limited. The author aims to identify risk factors correlated with the CHP.
Methods
82 patients with bCSDH who underwent the unilateral evacuation in Beijing Tiantan Hospital from 2011 to 2021 were included in this retrospective study. Clinical information and radiological features of these patients were collected and analyzed. Chi Square test, Student t test and Mann-Whitney test was performed to find variables which were statistically significant (p < 0.05), then multivariate analysis was applied to identify the independent risk factors.
Results
In our research, the progression rate was up to 13.41% (11/82). The mean age of CHP patients was significantly higher than non-CHP patients (72.45 ± 12.78 vs 62.85 ± 13.91, p = 0.025). Contralateral hematoma locating on the curved side was more likely to progress (p = 0.007). The other risk factors including pre- and post-operative volume of hematoma in the non-surgical side and the wide type of contralateral hematoma. The multivariate analysis demonstrated that the wide type of contralateral hematoma was one of the independent risk factors for CHP (OR = 8.769, p = 0.020, 95%CI 1.410-54.545). Moreover, the opposite hematoma locating on the curved side was also associated with the contralateral progression independently (OR = 7.103, p = 0.033, 95%CI 1.168–43.213).
Conclusion
For bCSDH patients, wide contralateral hematoma may increase the risk of CHP. Moreover, non-operative hematoma which locates on the curved side of skull is also an independent risk factor for the enlargement of opposite hematoma. Patients with such radiological characteristic may need additional medical treatment and rigorous follow-up to prevent the progression of contralateral hematoma.

Abstract
Aging adipose tissue shows elevated levels of inflammation, which can lead to age-related metabolic dysfunction. However, which metabolic changes in adipose tissue caused by aging are related to the occurrence of inflammation remain unclear. Therefore, we assessed the changes in metabolic phenotypes in the adipose tissue of 18 months adult sedentary (ASED) and 26 months old sedentary (OSED) rats compared with the tissue of 8 months young sedentary (YSED) rats used as the control group. Compared with YSED, ASED and OSED rats had increased body weight and Lee's index, and decreased grasp power and handing time. The expression of adipose tissue senescence-associated secretory phenotype (SASP) in the ASED and OSED groups was increased compared with that in the YSED group. The results of metabolomic studies showed increased levels of palmitic acid, elaidic acid, 1-heptadecanol, and α-tocopherol in the ASED and OSED groups compared with the YSED group, while sarcosine levels were decreased. Furthermore, stearic acid was specifically elevated in the ASED group. Cholesterol was upregulated, whereas linoleic acid and phosphate were specifically downregulated in the OSED group. The ASED group was associated with fatty acid biosynthesis and amino acid metabolism. In contrast, the OSED group was associated with fatty acid biosynthesis, steroid biosynthesis, amino acid metabolism, and linoleic acid metabolism. Additionally, increased levels of ferroptosis were found in both the ASED and OSED groups, whereas mitochondrial dysfunction due to abnormal cardiolipin metabolism was more pronounced in the OSED group. In conclusion, both the ASED and OSED can affect the lipid storage capacity of adipose tissue and oxidative stress leading to inflammation. Furthermore, OSED can further affect the metabolism of cardiolipin leading to abnormal mitochondrial function.
Considering ecosystem modeling by examining the creation of microcosms for Daphnia coexistence using an inorganic medium

Published: October 2022

Abstract
To conserve natural ecosystems, we require suitable experimental methods with which to investigate them. Ecosystem models, called microcosms, have the potential to predict and improve our understanding of the phenomena in natural ecosystems. However, it is known that there are discrepancies between microcosms and natural ecosystems, such as different phosphorus circulation depending on the scale of the microcosm. Therefore, it is necessary to understand why the differences appear and to consider the coexistence of species, the medium composition, and the internal structure of microcosms in order to reproduce more of the phenomena that occur in natural ecosystems. To address this, in this investigation a microcosm (DMC) was constructed in which a variety of organisms could coexist by circulating the necessary nutrients which had been biosynthesized from essential elements (31 elements) inserted into the medium as inorganic substances. The growth of Daphnia, which requires vitamins (B12, B1, B7), was then observed by changing the sediment inside the microcosm with the inorganic medium containing all the essential elements. Using quartz sand with a particle size of 0.3–0.6 mm as the sediment, resulted in the stable growth of Daphnia, from 3 to approximately 26 individuals over 35 days, due to the growth of algae such as diatoms, which are feed for Daphnia. This suggests that 0.5 mm particle spaces are suitable for anaerobic bacteria, and that the nutrients necessary for the organisms, such as vitamins, were biosynthesized from the essential elements in the space. These results indicate that the DMC, which can duplicate the cycles that occur in natural ecosystems, such as the production of nutrients from inorganic substances, and the diversification of organisms in the microcosm, will be a useful tool for understanding natural ecosystems and factors that impact them, such as the effects of chemicals.

Published: October 2022

Abstract
Recently waste to energy projects gaining more attraction due to rapid waste generation due to increased urbanization. Improper municipal solid waste (MSW) treatment resulting in environmental risks such as air pollution, ground, and surface water contamination. Anaerobic digestion (AD) is the best method to treat organic solid waste. Mono-AD of organic fraction of municipal solid wastes (OFMSW) leads to lower methane yield due to the accumulation of volatile fatty acids (VFAs). Mixing of two or more substrates (Co-digestion) dilutes the toxic compounds and increases the methane yield by providing proper environment for microbes. In this study anaerobic co-digestion (AcoD) of source segregated OFMSW (particularly food waste, fruit waste, and vegetable waste) with chicken fecal matter (co-substrate), and cow dung (inoculum) was investigated by using batch studies (Duration of 30 days). AcoD carried out in three different batch reactors viz. R1 (food mix), R2 (vegetable mix), and R3 (fruit mix) feed with substrates (S1& S2) and inoculum (I) (S1: S2: I = 0.5:0.5:2). The methane percentage obtained for reactor R1 was 69.60%, which is higher compared to the other reactors (R2- 61.2%, and R3- 57.37%). R1 reactor had higher methane yield due to its higher lipids (higher VFAs), and proteins (sufficient buffer capacity). R3 reactor had lowest methane yield due to its highest carbohydrates (rapid acidification), and lower proteins (lower buffer capacity). Modified Gompertz model gave better results near to experimental studies. The present study proved that mixing OFMSW with proper co-substrate (protein-rich) increases the methane yield by providing proper buffer capacity.

Abstract

Echinoderms are marine water invertebrates that are showing diverse morphologies and grouped in five classes, however the reports on this species from Gili Ketapang Island, East Java is currently limited. DNA barcodes (DNA fragments of the 5' end of the cytochrome c oxidase subunit I gene, COI) have been used to support the morphological examination in identifying evolutionary lineages. This study aims to identify the morphology and supplement of COI sequence and phylogenetic of Echinoderms from Gili Ketapang Island. A total of sixteen samples of Echinoderms were collected from Gili Ketapang, Probolinggo, Indonesia, then identified based on morphological characters, and supports identification was confirmed using molecular data. Subsequently, molecular characterization and identification was conducted based on 503 bp of COI gene similarity, sequence variation, genetic distance, phylogenetic topology, and BOLD System. According to the results, sixteen sample were identified asDiadema setosum;Macrophiothrix longipeda;Archaster typicus;Echinometra mathaei,Holothuria atra;Linckia laevigata,Bohadschia argus, andOphiactis savignyi.Each species was associated with a specific DNA barcode cluster and the relationship among these species was clearly revealed. Each species based on morphological identification and COI sequence clusters were congruent. The median joining network and Automatic Barcode Gap Discovery (ABGD) analysis showed thisEchinodermspopulation from Probolinggo had relatives of 14 haplotypes and divided into eight haplogroups. Furthermore, the population belonged to the same haplogroup but had different haplotypes. This newly records established sequence reference library for the Gili Ketapang Island.

Abstract
The existing research on the Internet of Vehicles (IoV) based on blockchain adopts the single chain mode. However, in the face of large-scale data environment, it is difficult to ensure the security and efficiency of large-scale data storage by using single chain. Thus, this paper is devoted to the research on the master-slave multi-chain IoV architecture. In the proposed architecture, there are two major innovations: 1) By defining three different data structures, micro-block, key-block and verification-block, the master-slave multi-chain model based on hash anchoring is designed to break through the data of the whole network. It ensures the consistency and integrity of IoV data, and solves the problem of privacy disclosure caused by insecure data storage; 2) A data upload and access mechanism based on attribute encryption is designed between users and RSU nodes. It solves the problem of privacy disclosure caused by insecure transmission outside the data chain. Finally, we verify that the proposed architecture is more suitable for large-scale data scenario by simulation analysis of system response time and encryption/decryption overhead.

Published: October 2022

Abstract
Electrical power is the base and backbone of all technologies and improvements, with an increase in load in day to day life, the need for utility has also grown up tremendously so as to fulfill the load requirements. Load flow study shows an insight regarding active and reactive power on each line, voltage phase angles on each bus and voltage losses on transmission lines, cables, transformers, and entire system of a grid. Short circuit study is most needed on electrical networks in order to properly size different equipment's and devices used in a system so as to properly handle short circuit currents. Stability analysis is essential for both design and performance monitoring for reliable and efficient grid operation. In this research work a vast and detailed investigation of status and performance evaluation of power system in North East Afghanistan had been performed. Particularly performance evaluation is applied on Afghanistan’s national power grid and concentrated on Kabul super grid. Kabul super grid is deeply evaluated by its modeling and performance evaluation. Evaluation of the network is performed based upon the power losses, voltage status, transmission line loading, and harmonic study as per the power flow results.

Abstract
The current work deals with the classification of NRFs system for reservoirs characterization of Cretaceous Kawagarh Formation along Bagnotar-Baragali Section, Lesser Himalaya Northern Pakistan. Surface fracture data were collected including orientation, attitude (Dip/Strike), fracture density (F.D), frequency and their distribution. The methodology implemented comprises of surface fracture data and subsequent statistical calculations by Monte Carlo equation followed by scanline circle inventory method. The data was collected from 198 different stations with 75 fractures inventories. The statistical data is then compared with the petrography, SEM and EDX data already available. Additional, the NFRs system was classified and recognised for the studied carbonate units based on the comparative analysis. Likewise, stress analysis was integrated with the results which displays that major stresses in NW directions whereas minor stresses were acting in NEE direction. The Stereonet diagram shows that the maximum fractures are NW-SE oriented, average amount of fracture are NE-SW oriented while Minimum amount of fracture are oriented in NEE-SWW direction. The fractures direction show three sets of joints making X-shape, which indicate that these fractures are interconnected and due to which the reservoir potential can be heightened. The average Fracture Density (FD), Porosity and permeability were calculated as 0.043136, 3.212509 and 0.282299 values respectively. The X-plots of Fracture Density (FD) vs. Porosity and Permeability is weak which decrease reservoir potential while the interrelationship of Fracture Porosity and permeability is very strong which yields supposed to enhancing reservoir potential of Kawagarh formation. The analysed formations show intermediate to low porosity and permeability and classified as Type 2 or Types 3 in NFRs system based on the Visual porosity (V.P) calculated from petrography and the fracture data from the outcrop. This further shows that, the fractures provide essential permeability only in case of types 2 while in case of type 3 the fractures provide a permeability assistance. Classification of Natural Fractured Reservoir (NFR) (Nelson, 2001) Shows that Kawagarh formation is type three (Poor) reservoir. The comparative analysis also shows that Kawagarh formation has a poor reservoir potential in Qamar Mela (Nizampur Basin) and Kala Chitta Ranges.
