Magnetic and structural properties of novel-coated multi-doped Ni–Co ferrite nanomaterial: Experimental and theoretical investigations

In this paper, the magnetic properties of Ni_0. 5Co_0. 5Fe_1. 59Mo_0. 1Gd_0. 2Sm_0. 1Tb_0. 01O_4 nanoparticles coated with oleic acid and prepared for the first time by the co-precipitation method were studied using magnetic property measurement system. TGA analysis was used to analyze the thermal behavior of the obtained precipitate. The formation of a pure phase of spinel nanoparticles with a mixed structure coated with oleic acid was confirmed by X-ray diffraction. The formation of crystallographic sites of spinel structure and the presence of oleic acid on the surface of nanoparticles was confirmed by infrared spectroscopy (FTIR). Transmission electron microscopy shows that the nanoparticles have a spherical shape morphology. The magnetic properties were determined at three different temperatures (5, 80, and 300 K) and revealed that the synthesized material has a superparamagnetic behavior. DFT calculations were performed to study the effect of doping the Ni–Co spinel ferrite with Mo, Sm, Tb, and Gd. Graphical abstract
Deflection Estimation of Truss Structures Using Inverse Finite Element Method

It is well recognized that strain and deflection data are important indexes to judge the safety of truss structures. Specifically, the shape sensing technology can estimate the deformation of a structure by exploiting the discrete strain data without considering the material property conditions. To fill the gap in which most of the methods in SHM (structural health monitoring) cannot be directly used to predict the displacement field, this paper proposed a novel inverse finite element method (iFEM) algorithm based on the equivalent stiffness theory. A deflection sensor is fabricated to focus on predicting the distributed deflection variation of the truss structure. The performance of the deflection sensor was evaluated by a calibration test and a stability test. Finally, it was applied to distributed deflection monitoring in the testing of truss structures. Results of all tests verify that the deflection sensor based on the i-FEM algorithm can predict the distributed deflection variation of the truss structure accurately, in real time, and dynamically.
Vanadium oxide thin film with improved sheet resistance uniformity

This paper reports on the deposition of vanadium oxide thin films with sheet resistance uniformity better than 2.5% over a 150 mm wafer. The resistance uniformity within the array is estimated to be less than 1%, which is comparable with the value reported for amorphous silicon-based microbolometer arrays. In addition, this paper also shows that the resistivity of vanadium oxide, like amorphous silicon, can be modeled by Arrhenius' equation. This result is expected to significantly ease the computation of the correction table required for TEC-less operation of VOx-based microbolometer arrays.
Social Isolation Does Not Alter Exploratory Behaviour, Spatial Learning and Memory in Captive Damaraland Mole-Rats (Fukomys damarensis)

Simple Summary Good exploration and navigational skills are important for subterranean mammals because they inhabit an energetically costly environment. Damaraland mole-rats are social animals, but in captivity, they can be housed in colonies or individually. Social isolation may have effects on their exploratory behaviour and memory performance. Overall, colony-housed and individually housed mole-rats explored readily, but single queens and non-breeding females were more active, possibly related to increased anxiety-like behaviour when housed individually. All groups, except single-housed non-breeding females, also showed improvements in solving a Y-maze, while both colony and single males made fewer errors in the maze over time. Thus, learning is probable but may have been underestimated in this experiment. In general, social isolation has a limited effect on Damaraland mole-rat exploration and spatial learning. Abstract Exploratory behaviour, spatial learning and memory affect the survival of animals and appear to be dependent on the specific habitat that a species occupies. Good spatial navigation and memory are particularly important for subterranean animals, as it is energetically expensive to inhabit this niche. Damaraland mole-rats are subterranean mammals that live in colonies with organised social structures. Damaraland mole-rats have been maintained in the laboratory for many years and can be housed in groups or individually. We evaluated the effect of social isolation on the exploratory behaviour and spatial memory of single-housed and colony-housed animals and also considered potential differences in animals with different social statuses. We predicted that solitary housing would increase anxiety-like behaviour and result in higher activity and more errors when solving a maze. Exploration by colony- and single-housed mole-rats was tested in an open-field test, where all individuals explored readily. Single-housed queens and non-breeding females showed increased activity and spent more time in tunnels, which can be explained by increased anxiety. In the Y-maze, improvements in solving the maze were observed in all experimental groups, except in single-housed non-breeding females. In addition, all males showed a decrease in the number of errors in the maze. Spatial learning is thus apparent but could not be conclusively proven. It was possibly underestimated, as magnetic cues that may be used by mole-rats as stimuli for navigation were removed in the experimental setup. Overall, it appears that social isolation has a limited effect on the exploratory behaviour and spatial learning of Damaraland mole-rats.
Wind Profiling by Coherent Doppler LIDAR with 2MICRON Solid Laser

Global wind profiling by a space-borne Doppler lidar with 2μm solid laser is expected to bring big progress in numerical weather prediction and the studies on global climate modeling. We have been conducting studies on the lasers for the space-borne coherent Doppler lidar to observe wind profiles and are developing a sub-scale laser with 500mJ output at 10Hz. Algorithm for wind profiling are investigated through ground-based and airborne wind observations by a coherent Doppler lidar. We are also making studies on systems for a demonstration of the global wind profiling by the space-borne coherent Doppler lidar.
Maintaining Continuity of Self as Perceived by People in the Early Stages of Dementia: A Qualitative Study

AIM: The purpose of this study is to shed light on the sense of self that occurs among those who have been diagnosed with the early stages of dementia, where the individual attempts to maintain continuity within their world. METHOD: The research was conducted using qualitative induction research methods and data were collected using semi-structured interview methods. The data were reported according to COnsolidated criteria for REporting Qualitative research (COREQ). RESULTS: The diagnosis was Alzheimer’s disease for all participants. Of the 15 participants, 6 were male and 9 female. The average age was 69.9 years. For those with the early stages of dementia, a sense of self that attempts to maintain continuity for the world in which they live is made up of the following: “living in the present while connecting to the past,” “relying on those that help to connect and fill in the gaps between the past, present, and very near future,” and “living daily life in one’s own world where past and present are connected. ” CONCLUSION: By understanding the sense of self that those who are diagnosed with the early stages of dementia experience while trying to maintain continuity within their world, one is able to get closer to their world and it is hoped that this may provide hints as to how to offer support in the future.
Telehealth Use in Pediatric Care during the COVID-19 Pandemic: A Qualitative Study on the Perspectives of Caregivers

This qualitative study surveyed caregivers regarding their perspectives on the benefits of, challenges with, and suggestions for improving telehealth during the COVID-19 pandemic. Caregivers who had the responsibility for caring for at least one child aged under 18 years of age in Genesee County, MI, participated. The caregivers were biological parents, stepparents, foster parents, adoptive parents, and guardians. A total of 105 caregivers completed a survey with open-ended questions via Qualtrics. Two independent coders developed themes based on the responses using grounded theory. Participants were primarily biological parents and non-Hispanic White and African Americans. According to the participants, the benefits of telehealth included prevention of exposure to the COVID-19 virus, quality communication with physicians, savings in travel time, and cost-effective methods to receive care. The challenges included a lack of in-person interaction, fear of compromised confidentiality, and the potential for misdiagnosis. Suggestions for improvement by caregivers included increasing access to telehealth for poorer families, offering a media educational campaign to promote telehealth use, and creating a universal platform to share patient information. Future studies may test the effectiveness of interventions such as those suggested by caregivers in this study to improve telehealth.
Veal and beef meat quality of crossbred calves from dairy herds using sexed semen and semen from double-muscled sires

Abstract The use of sexed semen to produce replacement heifers in dairy farms allows many cows to be inseminated with bulls of beef breeds with the aim of improving meat production. The major dairy and beef breeds are undergoing rapid genetic improvement as a result of more efficient selection methods, necessitating evaluation of the quality of meat produced by beef × dairy crosses obtained using current genetics. As part of a larger project, we carried out quantitative and qualitative evaluations of the veal and beef produced from crossbred calves produced by dairy farms that use sexed semen to obtain purebred replacement heifers. A total of 231 bull-calves were reared in the dairy farms or in specialised fattening farms, slaughtered, and sampled for meat quality analysis. These comprised: 104 crossbred calves, mainly from Belgian Blue sires and Holstein dams, which were intensively fattened for veal production; 84 beef × dairy crossbred calves, destined for beef production on the dairy farm of origin (12 calves) or in a specialised intensive fattening centre (72 calves); 26 purebred Charolais and 17 beef crosses from suckler cows, included for comparison, which were fattened in the same fattening centre and fed the same diet as the beef × dairy crosses. Veal and beef meat differed in all quality traits; the beef produced by dairy farmers was better than the beef produced by specialised fatteners in terms of cooking losses and tenderness, even though these animals were much older and weighed less at slaughter. There were minor differences in the quality traits of veal between the various beef × dairy breed combinations. In the case of intensive beef production, minor differences were observed between Belgian Blue-sired crosses from Brown Swiss cows (lipid content and shear force of meat) and Belgian Blue-sired crosses from crossbred cows (haem iron, lightness, yellowness, and hue) in comparison with crosses from Holstein cows. The beef of young bulls from suckler cows (Charolais and crosses) had a lower pH, dry matter and lipid contents, slightly higher cholesterol and haem iron contents, and higher cooking losses than meat from beef × dairy crosses. Taking into account the results from the entire project, we conclude that the combined use of sexed semen for pure-breeding and conventional beef semen for terminal crossbreeding improves meat production from dairy herds, both quantitatively and qualitatively. HIGHLIGHTS The meat from beef × dairy crossbred calves was found to have valuable qualitative characteristics. With regard to veal production, the meat quality characteristics of crossbred calves did not differ appreciably between breed combinations. With regard to intensive beef production, the meat from beef × dairy young bulls had greater quality than that from suckler cows. Crosses fattened by dairy farmers grew slower than those by specialised fatteners, but their beef was better in terms of cooking losses and tenderness.
Internet trade of a previously unknown wildlife product from a critically endangered marine fish

Online research methods are increasingly used in conservation science to monitor and collect data on online wildlife trade. Shark‐like rays (Rhinopristiformes) are among the most threatened vertebrates, prized for their high‐value fins while other uses for their derivatives are largely unrecognized in the literature. The bowmouth guitarfish (Rhina ancylostomus) is characterized by ridges of enlarged thorns, sometimes sold as amulets. Listed on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II, the thorn‐market has been ignored and undocumented. Using systematic, retrospective online searches, we recorded 977 bowmouth‐derivatives for sale. In our global and multi‐lingual scope, 97% of products were offered from Thailand, despite prohibited trade. 98% of all products were thorns (USD3‐300) and sold alongside high‐profile CITES‐listed taxa (e.g., tiger claws). Consistent advertisements from 2012 revealed a previously unquantified trade of an often‐neglected marketplace in elasmobranch research. Our findings offer insight into the drivers of the thorn trade, potentially rooted in cultural beliefs. Our accessible research methods can be applied internationally and across species, providing quantitative and qualitative insights on aspects of the wildlife trade of a critically endangered fish. Continued monitoring of online markets, like this study, is necessary to fill critical gaps for informed policy and species‐specific management.
T-cell Proliferation on Immunopathogenic Mmechanism of Psoriasis: a Control Based Theoretical Approach

Psoriasis vulgaris is a common, worldwide autoimmune skin disorder characterized by T-cells mediated hyperproliferation of keratinocytes. The feature of T-cells arbitrated psoriatic lesions is the epidermal infiltration of oligoclonal CD8 T-cells and also of CD4 T-cells in the dermis. Psoriatic scratches are identified by red and enlarged lesions along with silver whitish scales. In this article, we propose a mathematical model for psoriasis, involving a set of differential equations, concerning T-cells, dendritic cells and epidermal keratinocytes. We introduce T-cell proliferation in the system, where T-cells are generated through expansion of accessible CD4 T-cells from precursors. We are interested in observing how the cell biological system develops through T-cell proliferation in presence of control with respect to T-cells and keratinocytes. We study the model in both implicit and explicit ways and measure the effect of drug on the system through impulsive drug therapy.
Contextual Factors Associated with Abuse of Home-Dwelling Persons with Dementia: A Cross-Sectional Exploratory Study of Informal Caregivers

One in six community-dwelling older adults experience elder abuse yearly, and persons with dementia are especially at risk. Although many risk factors for elder abuse have been identified, there are still knowledge gaps concerning risk and protective factors. This cross-sectional survey among Norwegian informal caregivers (ICGs) aimed to find individual, relational, and community factors associated with psychological and physical abuse of home-dwelling persons with dementia. This study involved 540 ICGs and was conducted from May to December 2021. Statistical analysis using penalized logistic regression with lasso was performed to find covariates associated with psychological and physical elder abuse. The most prominent risk factor for both subtypes of abuse was the caregiver being a spouse. In addition, risk factors for psychological abuse were having a higher caregiver burden, experiencing psychological aggression from the person with dementia, and the person with dementia being followed up by their general practitioner. For physical abuse, the protective factors were the ICG being female and having an assigned personal municipal health service contact, while the risk factors were the ICG attending a caregiver training program and experiencing physical aggression from the person with dementia and the person with dementia having a higher degree of disability. These findings add to the existing knowledge of risk and protective factors in elder abuse among home-dwelling persons with dementia. This study provides relevant knowledge for healthcare personnel working with persons with dementia and their caregivers and for the development of interventions to prevent elder abuse.
A Multiomic Analysis of Chicken Serum Revealed the Modulation of Host Factors Due to Campylobacter jejuni Colonization and In-Water Supplementation of Eugenol Nanoemulsion

Simple Summary Campylobacter jejuni, a normal flora in the chicken gut, is one of the most common causes of bacterial gastroenteritis in humans, affecting approximately 95 million people worldwide. Carcass contamination at the processing plant through the leakage of gut contents can lead to foodborne illnesses when contaminated poultry or poultry products are consumed or improperly handled. This study focused on identifying host factors modulated by Campylobacter colonization in untreated chickens and those treated with phytochemical eugenol. We used a novel LCMS-based multiomics technology to identify the factors modulating the colonization of C. jejuni in broiler chickens. Three groups of broiler chickens were used: (1) negative control, (2) positive control, and (3) eugenol nanoemulsion (EGNE) treatment–supplemented with 0.125% EGNE in the water. Based on the multiomic analysis (proteins, lipids, and metabolites), we identified a few key host factors that were modulated with the colonization of C. jejuni. Abstract Campylobacter jejuni is a foodborne pathogen that causes campylobacteriosis globally, affecting ~95 million people worldwide. Most C. jejuni infections involve consuming and/or handling improperly cooked poultry meat. To better understand chicken host factors modulated by Campylobacter colonization, we explored a novel LCMS-based multiomic technology using three experimental groups: (1) negative control, (2) positive control, and (3) eugenol nanoemulsion (EGNE) treatment (supplemented with 0.125% EGNE in the water) of broiler chickens (n = 10 birds/group). Birds in groups two and three were challenged with C. jejuni on day 7, and serum samples were collected from all groups on day 14. Using this multiomic analysis, we identified 1216 analytes (275 compounds, seven inorganics, 407 lipids, and 527 proteins). The colonization of C. jejuni significantly upregulated CREG1, creatinine, and 3-[2-(3-Hydroxyphenyl) ethyl]-5-methoxyphenol and downregulated sphingosine, SP d18:1, high mobility group protein B3, phosphatidylcholines (PC) P-20:0_16:0, PC 11:0_26:1, and PC 13:0_26:2. We found that 5-hydroxyindole-3-acetic acid significantly increased with the EGNE treatment when compared to the positive and negative controls. Additionally, the treatment increased several metabolites when compared to the negative controls. In conclusion, this study revealed several potential targets to control Campylobacter in broiler chickens.
Pointing Control System Architecture for the Eclipse Mission

This paper describes the high performance pointing control system used to point the Eclipse telescope. Eclipse is a new mission under study at Jet Propulsion Laboratory for a proposal as a discovery mission. Eclipse is a space telescope for high-contrast optical astronomy. It will be used to investigate the planetary bodies and environments. The main objective of the Eclipse mission is to study planets around nearby stars. Eclipse is designed to reveal planets or dust structures by reducing the scattered and diffracted light within a few arcseconds of a star to a level three orders of magnitude lower than any instrument on the Hubble Space Telescope (HST). Eclipse achieves this high contrast using a 1.8 meter diameter telescope, a coronagraphic system for control of diffracted light, and active wavefront correction using a Precision Deformable Mirror (DM) for the suppression of scattered light. The observatory will be launched into a Sun-synchronous 690 Km, 98.2(deg) Earth Orbit in 2012.
CHIR99021 Maintenance of the Cell Stemness by Regulating Cellular Iron Metabolism

CHIR99021 is an aminopyrimidine derivative, which can efficiently inhibit the activity of glycogen synthesis kinase 3α (GSK-3α) and GSK-3β. As an essential component of stem cell culture medium, it plays an important role in maintaining cell stemness. However, the mechanism of its role is not fully understood. In the present study, we first found that removal of CHIR99021 from embryonic stem cell culture medium reduced iron storage in mouse embryonic stem cells (mESCs). CHIR99021-treated Neuro-2a cells led to an upregulation of ferritin expression and an increase in intracellular iron levels, along with GSK3β inhibition and Wnt/GSK-3β/β-catenin pathway activation. In addition, iron treatment activated the classical Wnt pathway by affecting the expression of β-catenin in the Neuro-2a cells. Our data link the role of iron in the maintenance of cell stemness via the Wnt/GSK-3β/β-catenin signaling pathway, and identify intermediate molecules, including Steap1, Bola2, and Kdm6bos, which may mediate the upregulation of ferritin expression by CHIR99021. These findings reveal novel mechanisms of the maintenance of cell stemness and differentiation and provide a theoretical basis for the development of new strategies in stem cell treatment in disease.
Phenotyping of Silique Morphology in Oilseed Rape Using Skeletonization with Hierarchical Segmentation

Silique morphology is an important trait that determines the yield output of oilseed rape (Brassica napus L.). Segmenting siliques and quantifying traits are challenging because of the complicated structure of an oilseed rape plant at the reproductive stage. This study aims to develop an accurate method in which a skeletonization algorithm was combined with the hierarchical segmentation (SHS) algorithm to separate siliques from the whole plant using 3-dimensional (3D) point clouds. We combined the L1-median skeleton with the random sample consensus for iteratively extracting skeleton points and optimized the skeleton based on information such as distance, angle, and direction from neighborhood points. Density-based spatial clustering of applications with noise and weighted unidirectional graph were used to achieve hierarchical segmentation of siliques. Using the SHS, we quantified the silique number (SN), silique length (SL), and silique volume (SV) automatically based on the geometric rules. The proposed method was tested with the oilseed rape plants at the mature stage grown in a greenhouse and field. We found that our method showed good performance in silique segmentation and phenotypic extraction with R2 values of 0.922 and 0.934 for SN and total SL, respectively. Additionally, SN, total SL, and total SV had the statistical significance of correlations with the yield of a plant, with R values of 0.935, 0.916, and 0.897, respectively. Overall, the SHS algorithm is accurate, efficient, and robust for the segmentation of siliques and extraction of silique morphological parameters, which is promising for high-throughput silique phenotyping in oilseed rape breeding.
