Published: March 2022

Abstract
SVOM is a Sino-French cooperation project aiming at Gamma Ray Burst observation. From the top level requirement, during the observation period, the satellite platform should provide a stability of better than 1.6 arcsec/100s. Based on this severe requirement, a high precision attitude measurement device is strongly demanded. This article describes the overall design of a novel optical sensor, called Fine Guidance Sensor, for the SVOM Satellite. First, the functional and performance requirements are presented, including the extremely high measuring precision of 0.3 arcsec in y/z-axis. Second, FGS composition, including hardware and software, and processing flow design are described. Then, working mode switching logic is introduced. Next, attitude determination method and simulation result are shown. The conclusion is obtained and all the required indexes are fulfilled by current FGS design.
An Optimal Design Scheme of Missile Trajectory
Authors: Zhang Shilin 
Published: March 2022

Abstract
The optimization of missile trajectory is an important part of missile design. Its difficulty lies in the complex force of the missile and the different laws of the trajectory parameters in each stage. The existing trajectory simulation models have problems such as complex models, low accuracy, simplifying the initial motion state of the missile, and failing to fully reflect the characteristics of the active and passive motions. In order to solve these problems, this paper extracts important model variables on the basis of analyzing the force of the missile at different stages, and establishes a ballistic model with time-varying parameters. At the same time, according to the engineering design method of the missile flight program, the change rule of the pitch angle of the active phase of the missile with time is drawn up. Finally, an intercontinental ballistic missile is used as the object to simulate and analyze the proposed model. The results show that the method proposed in this paper can design and optimize missile trajectory well.

Abstract
We present the analysis and results of the first dataset
collected with the MARS neutron detector
deployed at the Oak Ridge National
Laboratory Spallation Neutron Source (SNS) for the purpose of
monitoring and characterizing the beam-related neutron (BRN) background
for the COHERENT collaboration. MARS was positioned
next to the COH-CsI coherent elastic neutrino-nucleus scattering detector
in the SNS basement corridor. This is the basement location of
closest proximity to the SNS target and thus, of highest neutrino flux,
but it is also well shielded from the BRN flux by infill concrete
and gravel. These data show the detector registered roughly one BRN per day.
Using MARS' measured detection efficiency, the incoming
BRN flux is estimated to be 1.20 ± 0.56 neutrons/m^2/MWh
for neutron energies above ∼3.5 MeV and up to a few tens of MeV.
We compare our results with previous BRN measurements in the SNS basement corridor
reported by other neutron detectors.

Published: March 2022

Abstract
Grafting of bone-substitute biomaterials plays a vital role in the reconstruction of bone defects. However, the design of bioscaffolds with osteoinductive agents and biomimetic structures for regeneration of critical-sized bone defects is difficult. Ti3C2 MXene—belonging to a new class of 2D nanomaterials—exhibits excellent biocompatibility, and antibacterial properties, and promotes osteogenesis. However, its application in preparing 3D-printed tissue-engineered bone scaffolds for repairing bone defects has not been explored. In this work, Ti3C2 MXene was incorporated into composite scaffolds composed of hydroxyapatite and sodium alginate via extrusion-based 3D printing to evaluate its potential in bone regeneration. MXene composite scaffolds were fabricated and characterized by SEM, XPS, mechanical properties and porosity. The biocompatibility and osteoinductivity of MXene composite scaffolds were evaluated by cell adhesion, cell counting kit-8 test, quantitative real-time polymerase chain reaction, alkaline phosphatase activity and alizarin red S tests of bone mesenchymal stem cells (BMSCs). A rat calvarial defect model was performed to explore the osteogenic activity of the MXene composite scaffolds in vivo. The results showed the obtained scaffold had a uniform structure, macropore morphology, and high mechanical strength. In vitro experimental results revealed that the scaffold exhibited excellent biocompatibility with BMSCs, promoted cell proliferation, upregulated osteogenic gene expression, enhanced alkaline phosphatase activity, and promoted mineralized-nodule formation. The experimental results confirmed that the scaffold effectively promoted bone regeneration in a model of critical-sized calvarial- bone-defect in vivo and promoted bone healing to a significantly greater degree than scaffolds without added Ti3C2 MXene did. Conclusively, the Ti3C2 MXene composite 3D-printed scaffolds are promising for clinical bone defect treatment, and the results of this study provide a theoretical basis for the development of practical applications for tissue-engineered bone scaffolds.
Exact time evolution formulae in the XXZ spin chain with domain wall initial state
Authors: Stéphan Jean-Marie 
Published: March 2022

Abstract
We study the time evolution of the spin-1/2 XXZ chain initialized in a domain wall state, where all spins to the left of the origin are up, all spins to its right are down. The focus is on exact formulae, which hold for arbitrary finite (real or imaginary) time. In particular, we compute the amplitudes corresponding to the process where all but k spins come back to their initial orientation, as a k-fold contour integral. These results are obtained using a correspondence with the six vertex model, and taking a somewhat complicated Hamiltonian/Trotter-type limit. Several simple applications are studied and also discussed in a broader context.

Published: March 2022

Abstract
Chitosan films are increasingly being applied in the biomedical field owing to their biocompatibility, biodegradability, non-toxicity, mucoadhesive nature, hemostatic properties, antibacterial and biological activities. This study aimed to enhance the mechanical properties of chitosan films by doping niosomal sage nanoparticles (NS-SagNPs) at various concentrations (100–300 μg). The NS-SagNPs were prepared by a thin-film hydration process with an average particle size of 21.5 nm. The doped chitosan films were fabricated through a simple casting method. FTIR and DSC measurements confirmed the successful incorporation of NS-SagNPs in the chitosan films. The mechanical properties of the doped films were improved and the most significant improvement was found in tensile strength and elasticity when the NS-SagNPs loading was increased to 300 μg. Based on these results, chitosan films doped with NS-SagNPs have the advantageous feature of sage and show enhanced mechanical properties compared with pure chitosan, rendering them more suitable for biomedical applications.
Inverse synthetic aperture radar range profile compensation of plasma-sheath-enveloped reentry object

Published: March 2022

Abstract
The scattering points in a plasma sheath characterized with coupled velocities can cause pulse compression mismatching, which results in displacement and energy diffusion in the one-dimension range profile. To solve this problem, we deduce the echo model of the plasma-sheath-enveloped reentry object. By estimating the coupled velocities, we propose a compensation method to correct the defocus of an inverse synthetic aperture radar (ISAR) image in range dimension to improve the quality of the ISAR images. The simulation results suggest that the echoes from different regions of the surface of the reentry object have various coupling velocities, and the higher the coupled velocity, the more serious the displacement and energy diffusion in the range dimension. Our proposed method can correct the range dimension aberration. Two measurement metrics were used to evaluate the improvement of the compensation method.

Published: March 2022

Abstract
In this work, the influence of the electrode surface roughness on the self-breakdown gas switch is investigated by physical analysis, computer simulation and experiment. Cu-W electrodes of different surface roughness were tested under the conditions of a pulse repetitive frequency of 50 Hz, self-breakdown voltage of ∼30 kV, and peak current of ∼2 kA for ∼93000 shots (the total charge transferred was ∼15 C). The coefficients of variation of the self-breakdown voltage of Cu-W 0.8, Cu-W 3.2 and Cu-W 12.5 electrodes were ∼2.95%, ∼1.62% and ∼1.16%, respectively. With the increase of electrode roughness, the erosion area decreased continuously, indicating that the breakdown positions were more stable and the coefficient of variation of breakdown voltage decreased. The method showed that decreasing the coefficient of variation of the self-breakdown voltage by increasing the surface roughness of electrode greatly improves the stability of the self-breakdown switch, which is significant for their application in compact high-power pulse power devices over a long time with stable operation.
All-in-one electrochromic transparency-tuning window with an integrated metal-mesh heating film

Published: March 2022

Abstract
Electrochromic (EC) smart windows with transparency-tuning capability can provide buildings with effective sun-shading and privacy to occupants at low energy consumption. The essential requirements to EC windows are fast response, dynamic tunability and low-cost. Recent development in all-in-one electrochromic devices (ECDs) which combines electrolyte, EC and ion storage functions in a single gel has the advantage of single layer structure and can be manufactured in large areas at low cost. However, the coloring voltage and time of all-in-one ECDs can be influenced by the viscosity of active gel. By raising the working temperature, the ECD may have faster response time and lower coloring voltage due to reduced gel viscosity. To enable high working temperature, a high conductivity and high transparency metal-mesh heating film was integrated to an EC window glass. The coloring performance of the EC window was investigated at different heating temperatures compared to its room temperature performance. It was found that working at 70 °C the coloring efficiency was doubled and the response speed of the device is five times faster than that at room temperature. The integrated metal-mesh heating film also brought added benefits such as defog and defrost for car windshield.

Published: March 2022

Abstract

Objectives
We investigated the feasibility and utility of next-generation sequencing (NGS)–based targeted somatic mutation panels and IG/TR gene rearrangement assays in the diagnosis of lymphoproliferative disorders (LPDs) in small-volume biopsies.

Materials
We performed a retrospective, single-institution review of all NGS assays requested over a 3-year period by hematopathologists for diagnostic purposes on small-volume biopsies.

Results
We identified 59 small-volume biopsies. The TR assay was most commonly requested (42 [71%]), followed by the somatic mutation panel (32 [54%]) and IG assay (26 [44%]). NGS studies were associated with a change in the diagnostic line in about half of cases (28 [47%]) and in a change in the likelihood of a diagnosis in a further 16 cases (27%); there was no diagnostic impact of NGS testing in 15 cases (25%).

Conclusions
Implementation of NGS panel somatic mutation or IG/TR gene rearrangement assays on small-volume biopsies contributes to the diagnosis of LPDs in the majority of select cases for diagnostic purposes. The molecular diagnosis is considered in the context of the clinical, histologic, and immunophenotypic findings and does not by itself lead to a definitive diagnosis in small-volume biopsies.
Biometric Bordering and Automatic Gender Recognition: Challenging Binary Gender Norms in Everyday Biometric Technologies
Authors: Quinan C L , Hunt Mina 
Published: March 2022

AbstractWith the rise of advanced biometric technologies, the surveilling of populations who do not match racial and gender norms has increased. Modern-day biometrics make assumptions about gender and race based on skin color, facial structure, body type, and body parts, which are encoded in predictive algorithms and other AI-driven systems. Growing empirical evidence points to the obstacles this poses for trans and non-binary individuals in several spheres, including border security, healthcare, and social media. Drawing on autoethnographic vignettes, semi-structured interviews, and survey responses, we look to the increased use of binary-based biometric technologies and automatic gender recognition (AGR), which rely on outmoded understandings of gender as static, measurable, and physiological. Our ethnographic data demonstrate how trans and non-binary bodies are forced to bend to these systems; meanwhile these technologies and algorithms increasingly extract data on trans and non-binary users, which may then be used as challenge sets to refine their accuracy.

Published: March 2022

Abstract
Natural forests of Cyclocarya paliurus have been seriously damaged because of the extreme demand for leaf medicinal uses, making conservation of this valuable, medicinal woody species necessary. Because of geographical differentiation and diverse adaptability, in this study we analysed the variations in plant growth and physiological response to environmental factors at a resource plantation of ex situ conservation and determined the homological relationships between local provenance (from Fujian Province, FJ) and introduced provenances showing high-survival rate and better growth (from Zhejiang, Hubei, Guizhou and Jiangxi Province). Our results suggested the following: (i) Plant growth: FJ had the highest plant height but not the largest basal diameter in comparison to that of other provenances. (ii) Physiological responses during the growth periods: water content in leaf of FJ had similar change with that of other provenances, except for the provenance from Guizhou Province; total soluble sugar content in leaf of FJ was more than that of other provenances; calcium content in leaf of all provenances was higher as compared to K, Mg and Na; the highest activity among four kinds of antioxidant enzymes in all provenances was superoxide dismutase, then was polyphenol oxidase and peroxidase, finally was catalase; and total flavonoid among three kinds of secondary metabolites in all provenances showed the greatest content, followed by polysaccharides and total triterpenoid. (iii) Relation analysis: plant growth and physiological responses related with environmental factors, especially temperature and precipitation. (iv) Homological relationships: leaf characteristics among six provenances varied in colour, area and common petiole length, but not the shape of leaf base or apex. Cyclocarya paliurus distributed in Fujian Province showed a very close homological relationship with that distributed in Zhejiang Province by simple sequence repeat. These findings will provide knowledge on physiological response to environmental factors and aid to select suitable provenances for Cyclocarya cultivation.

Abstract
The kidney is a complex organ that consists of various types of cells. It is occasionally difficult to resolve molecular alterations and possible perturbations that the kidney experiences due to drug-induced damage. In this study, we performed spatial and single-cell transcriptome analysis of rat kidneys and constructed a precise rat renal cell atlas with spatial information. Using the constructed catalogue, we were able to characterize cells of several minor populations, such as macula densa or juxtaglomerular cells. Further inspection of the spatial gene expression data allowed us to identify the upregulation of genes involved in the renin regulating pathway in losartan-treated populations. Losartan is an angiotensin II receptor antagonist drug, and the observed upregulation of the renin pathway-related genes could be due to feedback from the hypotensive action of the drug. Furthermore, we found spatial heterogeneity in the response to losartan among the glomeruli. These results collectively indicate that integrated single-cell and spatial gene expression analysis is a powerful approach to reveal the detailed associations between the different cell types spanning the complicated renal compartments.
The impact of non-response weighting in health surveys for estimates on primary health care utilization
Authors: Jensen Heidi Amalie Rosendahl , Lau Cathrine Juel , Davidsen Michael , Feveile Helene Birgitte , Christensen Anne Illemann , Ekholm Ola 
Published: March 2022

Abstract

Background
Low response rates in health surveys may affect the representativeness and generalizability of results if non-response is systematically related to the indicator of interest. To account for such potential bias, weighting procedures are widely used with an overall aim to obtain less biased estimates. The aim of this study was to assess the impact of applying calibrated weights on prevalence estimates of primary health care utilization among respondents compared to the entire sample of a representative Danish survey of adults aged ≥16 years.

Methods
Registry-based 1-year prevalence data on health care utilization of chiropractor/physiotherapist, dentist and psychologist in 2016 were linked to the entire sample (n = 312 349), including respondents (n = 183 372), from the Danish National Health Survey in 2017. Calibrated weights, which applied information on e.g. sex, age, ethnic background, education and overall health service use were used to assess their impact on prevalence estimates among respondents.

Results
Across all included types of health care, weighting for non-response decreased prevalence estimates among respondents, which resulted in less biased estimates. For example, the overall 1-year prevalence of chiropractor/physiotherapist, dentist and psychologist utilization decreased from 19.1% to 16.9%, 68.4% to 62.5% and 1.9% to 1.8%, respectively. The corresponding prevalence in the entire sample was 16.5%, 59.4% and 1.7%.

Conclusions
Applying calibrated weights to survey data to account for non-response reduces bias in primary health care utilization estimates. Future studies are needed to explore the possible impact of weighting on other health estimates.

Abstract
The publication of the Caenorhabditis briggsae reference genome in 2003 enabled the first comparative genomics studies between C. elegans and C. briggsae, shedding light on the evolution of genome content and structure in the Caenorhabditis genus. However, despite being widely used, the currently available C. briggsae reference genome is substantially less complete and structurally accurate than the C. elegans reference genome. Here, we used high-coverage Oxford Nanopore long-read and chromosome-conformation capture data to generate chromosome-level reference genomes for two C. briggsae strains: QX1410, a new reference strain closely related to the laboratory AF16 strain, and VX34, a highly divergent strain isolated in China. We also sequenced 99 recombinant inbred lines generated from reciprocal crosses between QX1410 and VX34 to create a recombination map and identify chromosomal domains. Additionally, we used both short- and long-read RNA sequencing data to generate high-quality gene annotations. By comparing these new reference genomes to the current reference, we reveal that hyper-divergent haplotypes cover large portions of the C. briggsae genome, similar to recent reports in C. elegans and C. tropicalis. We also show that the genomes of selfing Caenorhabditis species have undergone more rearrangement than their outcrossing relatives, which has biased previous estimates of rearrangement rate in Caenorhabditis. These new genomes provide a substantially improved platform for comparative genomics in Caenorhabditis and narrow the gap between the quality of genomic resources available for C. elegans and C. briggsae.
