Abstract
Purpose The aim of this study was to compare accuracy of shear-wave elastography (SWE) with gray scale (GS) ultrasound and power Doppler (pD) for diagnosing Achilles tendinopathy in psoriatic patients with and without arthritis and correlation with achillodynia and disease severity score, psoriasis area and severity index (PASI).
Methods A total of 100 Achilles tendons were evaluated where 56% were cases of psoriatic arthritis with achillodynia; 44% were controls of psoriasis without arthritis in this prospective study. Evaluation was done with GS, pD, SWE at proximal, mid, and distal third of the tendon. Qualitative (color maps) and quantitative data, elastic modulus, kilopascal (kPa), were generated. Pearson's correlation was done to see association between kPa, PASI and clinical symptoms, achillodynia, scored using visual analog scale (VAS).
Results Significant negative correlation was seen between duration of arthritis, VAS and PASI with SWE values with r = −0.34, −0.47, and −0.41, respectively. SWE could identify abnormal tendons in 71/100 (71%) in the overall study, 53/56 (94.6%) in cases, and 18/44 (40.9%) in control. The statistical significance was set at p ≤ 0.05. In comparison, conventional ultrasound, GS, and pD together could identify 13/56 (23.21%) in cases and no abnormal tendon was identified in the control group.
Conclusion SWE is a reliable, noninvasive, and valuable tool to detect early tendinopathy and monitor progression of disease.

AbstractParental health before conception effects maternal and offspring health outcomes. Preconception care provides healthcare to prospective parents addressing modifiable preconception risks and health behaviors. This umbrella review aimed to consolidate evidence on women's and men's modifiable preconception risks or health behaviors associated with maternal and offspring health outcomes. MEDLINE, EMBASE, Maternity and Infant Care, CINAHL, and PsycINFO were searched from March 4, 2010, to March 4, 2020. Eligible studies were systematic reviews or meta-analyses of observational studies examining associations between modifiable preconception risks or health behaviors and maternal and offspring health outcomes. Screening, data extraction, and methodological quality assessment (AMSTAR 2) occurred independently by two reviewers. Degree of overlap was examined. Findings were summarized for evidence synthesis. Twenty-seven systematic reviews were included. Modifiable preconception risks and health behaviors were identified across categories: body composition (e.g., overweight, obesity), lifestyle behaviors (e.g., caffeine, smoking), nutrition (e.g., micronutrients), environmental exposures (e.g., radiation), and birth spacing (e.g., short interpregnancy intervals). Outcomes associated with exposures affected embryo (e.g., embryonic growth), maternal (e.g., gestational diabetes mellitus), fetal/neonate (e.g., preterm birth), and child (e.g., neurocognitive disorders) health. For real-world practice and policy relevance, evidence-based indicators for preconception care should include body composition, lifestyle, nutrition, environmental, and birth spacing.

AbstractThis study aimed at evaluating how transition of care is currently being organized in the European Reference Networks (ERNs) health care providers (HCPs) in pediatric areas and in the Anorectal Malformation Network (ARM-Net) Consortium hospitals. An online questionnaire was sent to a total of 80 surgeons, members of or affiliated members of three networks: ARM-Net Consortium, ERN eUROGEN, and ERN ERNICA. Complete information were obtained for 45 HCPs, most of which deal with transition and still see a few adult patients (ca. 10%). Gynecological, gastroenterological, urological, colorectal, and continence issues were the major problems described by adult patients to their physicians, and in line with these prevalent complaints, they are referred to the appropriate adult specialists. Forty percent of patients complain about sexual and fertility problems, but the percentage of andrologists and sexologists involved in the caring of adult patients with ARM/Hirschsprung's disease is low, just above 10.9%. Most hospitals deal with transition, but three basic criteria (i.e., presence of: [1] an official written transitional program, [2] a transitional coordinator, and [3] written information on transition to be handled to patients) are jointly met only by six HCPs. According to the responders, the most important issue requiring improvement is the lack of interest and of specific preparation by adult specialists. The overall results of this exploratory survey confirm the need for the development of comprehensive programs for transition in these rare and complex diseases, and identify the hospitals that, in collaboration with the networks, could share best practices in organizing structured transitional pathways and well follow-ups.

Abstract
Introduction Finding biomarkers for highly lethal cancers is a priority.
Objective The current study was designed to understand the clinical significance of vascular endothelial growth factor (VEGF), latent membrane protein 1 (LMP1), and tumor necrosis factor-α (TNF-α) expression as the biomarkers, and evaluate their correlation with each other, in nasopharyngeal carcinoma (NPC) in the province of Guilan, North of Iran.
Methods Gene expression was evaluated in 25 formalin-fixed paraffin-embedded (FFPE) blocks from cases of confirmed NPC and 20 FFPE samples of non-NPC by quantifying messenger ribonucleic acid (mRNA) and protein levels, using real-time polymerase chain reaction (PCR) and immunohistochemistry (IHC) methods, respectively. Furthermore, the correlations among the protein levels of different genes, along with the patients' demographic characteristics were assessed.
Results Our findings on mRNA and protein levels demonstrated that the expression of the LMP1 gene in the NPC group was significantly elevated compared with that of the non-NPC group. In addition, the protein levels in the NPC group indicated a positive and significant correlation between LMP1 and VEGF expression. It was noted that both protein and mRNA levels showed no significant differences in the expression of TNF-α and VEGF genes between the NPC and control groups. Furthermore, there was no significant relationship between the expression of these proteins and the demographic characteristics of NPC patients.
Conclusion Overall, a significant increase in LMP1 expression was observed in NPC patients, which may serve as a diagnostic biomarker for NPC. Also, LMP1 might be involved in NPC progression by inducing VEGF gene expression.

AbstractThe aim of this study was to report patellar groove replacement in a 6-year-old domestic short hair cat with chronic unilateral pelvic limb lameness and severe femoro-patellar osteoarthritis due to medial patellar luxation. This study is a case report. Computed tomographic scan of the affected limb revealed marked periarticular osteophytosis, medial trochlear ridge erosion, marked flattening of femoral trochlea, ectopic pseudo-trochlear groove, and medial patellar luxation. Femoral trochlear ostectomy with patellar groove replacement, release of the medial fibrocartilage, partial parasagittal patellectomy, and lateral tibial tuberosity were performed. Clinical review and radiographs performed 53 days post-surgery revealed no complications and substantial decrease in lameness. Thirteen months postoperatively the cat scored 2/72 on the Feline Musculoskeletal Pain Index questionnaire by the owner, indicating good mobility, minimal discomfort, and good quality of life. As far as the authors are aware, this is the first report of the use of patellar groove replacement in the management of feline medial patellar luxation. Patellar groove replacement, in combination with adjunctive procedures, resulted in a substantial improvement in lameness in this cat with chronic medial patellar luxation and severe femoro-patellar osteoarthritis.

Context Panicum coloratum is a relatively undomesticated small-seeded warm-season forage grass. Seed shattering, an extended reproductive period and non-synchronic seed maturation limit harvested seed yields. Low seed quantity and quality hinder pasture establishment and discourage its use. Aims To assess whether seed yield potential could be improved by breeding, we sought to measure variability in traits related to seed production including phenotypic plasticity in response to environmental cues, and estimated narrow-sense heritability, prospective genetic gain after selection and co-heritabilities in seed yield components. Methods Seed retention (SR), number of panicles (PN), seed number per panicle (SN) and seed weight (SW) were measured in plants growing in the field. Clonal replicates of 13 genotypes were assessed in 2007 and 2010 and half-sib families derived from these genotypes were measured in 2010. Key results Phenotypic variability among genotypes was related to genetic factors for all measured variables. Two broad groups of accessions showing differences in SR were studied. Phenotypic plasticity in SR differed among genotypes and was negatively related to levels of SR, implying that stable high-SR genotypes could be selected in a breeding program. Maximum narrow-sense heritabilities were 0.89 and 0.41 for SN and SR, respectively, with estimated gains after selection around 30%. The best results were achieved if selecting for SR at 3–5 weeks after anthesis. Low genetic correlations and extremely low co-heritabilities between other characters and seed yield components discourage the possibility of indirect selection. Conclusion Moderate increases in seed production potential may be achieved after selection for SN, SW and SR in P. coloratum var. makarikariense. Implications Improvements in SR and other seed yield components would facilitate harvest, increase yield and consequently increase profitability to growers and stimulate pasture adoption by farmers.

Context Studies of Phoma black stem and leaf spot disease (caused by Phoma medicaginis) in annual medics (Medicago spp.) normally involve a ‘once-only’ inoculation not reflecting multiple pathogen infection and phytoestrogen production cycles in the field. Phytoestrogen production by plants can result in lower ovulation rates in grazing animals. Aims We aimed to determine whether sequential infections by P. medicaginis increase production of phytoestrogens in annual medics, and to measure the genetic diversity of isolates. Methods In a greenhouse experiment, pathogenicity and virulence were investigated across 32 isolates of P. medicaginis following one, two or three rounds of inoculation of M. polymorpha var. brevispina. Production of the phytoestrogens coumestrol and 4′-O-methyl coumestrol was measured, and correlation with disease parameters assessed. DNA sequencing using ITS, β-tubulin, calmodulin and P. medicaginis-specific EFNI-1α was applied for phylogenetic analysis of isolates from Western Australia and elsewhere. Key results Across isolates, highest leaf disease incidence was 76%, petiole disease incidence 61%, leaf disease severity 52% and petiole disease severity 53%. Stem coumestrol content range was 45–1247 mg kg−1, and 4′-O-methyl coumestrol 0–344 mg kg−1. All measures were highest after three rounds of inoculation. Overall, there was a positive correlation of leaf disease incidence with coumestrol content (P < 0.05) and of both leaf and petiole disease incidence with 4′-O-methylcoumestrol content (P < 0.01, P < 0.05, respectively). Phylogenetic analysis revealed a high degree of genetic similarity among Western Australian isolates, generally grouping into a single separate cluster across the four markers, and genetically distinct from isolates sourced outside Australia. Conclusions Leaf disease incidence was the best discriminating disease parameter for coumestrol and 4′-O-methylcoumestrol content. Western Australian isolates of P. medicaginis were genetically similar and unique, possibly due to geographic separation. Implications The study emphasised the importance of sequential inoculations when screening annual Medicago genotypes towards developing cultivars with superior disease resistance and enhanced animal reproductive outcomes.

Thermal transport in porous graphene with coupling effect of nanopore shape and defect concentration

Published: July 2022

Abstract
Thermal conductivity of porous graphene can be affected by defect concentration, nanopore shape and distribution, and it is hard to clarify the effects due to the correlation of those factors. In this work, molecular dynamics simulation is used to compare the thermal conductivity of graphene with three shapes of regularly arranged nanopores. The results prove the dominant role of defect concentration under certain circumstances in reducing thermal conductivity, while the coupling effect of nanopore shape should be noticed. When the atoms at the local phonon scattering area around each nanopore are properly removed, the abnormal increment of thermal conductivity can be detected with the increase of defect concentration. Heat flux vector angles can effectively characterize the local phonon scattering area, which can be used to describe the effect of nanopore shape. The coupling effect of defect concentration and pore shape with similar heat flux path is clarified according to this process. By adjusting vertex angle of triangle defect, there is a balanced state of the effect factors between the variation of defect concentration and the same phonon scattering area. It provides a possible way to describe the weighing factors of the coupling effect. The results suggest a feasible approach to optimize and regulate thermal properties of porous graphene in nanodevice.

Abstract
Spinel Co3O4 nanospheres have been synthesized by the microwave-assisted hydrothermal method. The N-doped graphene nanosheets (NGN) were synthesized using Hummer’s method. The prepared spinel Co3O4 and NGN were mixed under certain proportions using an ultrasonication process and treated with microwave radiation to prepare a novel spinel Co3O4 nanospheres infused NGN. The synthesized samples were characterized by x-ray diffraction, Raman spectroscopy, Zetasizer, scanning electron microscope/transmission electron microscopy and x-ray photoelectron spectroscopy for identifying crystal structure and phase, particle size, and the morphology of the nanostructure and the elemental configuration, respectively. The prepared spinel Co3O4/NGN were used as anode material and lithium metal as a reference electrode to fabricate half cell using Swagelok cell components. The electrochemical properties were studied and found to exhibit a larger specific capacity of 575 mAh g−1 compared to traditional graphite electrodes, after 100 cycles under 0.1 C rate with a coulombic efficiency of ≈100%. The good electrochemical properties ascribe to the distinctive surface morphological nanostructures of nanoporous nanospheres of spinel Co3O4 nanospheres and nanosheets of N-doped graphene that reduce the lithium-ion diffusion pathway. The developed anode material would be a potential electrode for lithium ion battery applications.
A giant self-Kerr nonlinearity using phase-sensitive excitation in a closed three-level atomic system
Authors: J Ayyappan , T Beena 
Published: July 2022

Abstract
A third-order nonlinear response is investigated theoretically using a closed lambda system. In this scheme, a pair of optical fields and a microwave field connect three hyperfine levels in a cyclic fashion, rendering the atomic response sensitive to the relative phase of all three fields. Changing the relative phase, we can suppress the linear response of the probe field and enhance its third order self-Kerr nonlinear response using the underlying electromagnetically induced transparency (EIT) effect. The resultant giant self-Kerr nonlinear response is comparable to or exceeding that found in atomic systems at room temperature. Most importantly, we show that the self-Kerr nonlinear response at an optical frequency can be controlled using the phase and amplitude of a frequency-separated microwave field.

Published: July 2022

Abstract
The lasing medium of cryo-cooled CW-CO laser operated with CO2 laser gain medium (CO2–N2–He mixture) resulting in 5 µm emission is formed in-situ in the discharge and its composition, that is sensitively dependent on the discharge temperature, is not known a priori. The composition of the CO lasing gas mixture here was successfully arrived at by way of sampling the gas mixture at the exhaust and measuring the wavelength dependent absorbance by a Fourier Transform Infrared Spectrophotometer. This enabled us to determine the CO and CO2 concentrations in the lasing mixture accurately while the other major constituents were estimated from the initial partial pressures. The composition of the lasing gas mixture was studied for various discharge wall temperatures starting from no cooling condition (∼351 K) to LN2 cooled conditions (79 K). While the concentrations of both, CO2 and CO were found to decrease for temperatures below the freezing point of CO2 at the operating pressure of 11 mbar, the relative concentration of CO with respect to CO2 also increased with reducing temperature accompanied by a steady increase in the CO laser power output. The onset of lasing in 5 µm region was found to occur at a discharge wall temperature of 212 K.

Authors: Zhang Han , Meng Lijun 
Published: July 2022

Abstract
Compared with ordinary gratings, phase-shifted fiber gratings have better ultrasonic response sensitivity and higher upper response frequency. The application of phase-shifted fiber gratings in ultrasonic signal detection has gradually become a research hotspot. This paper mainly introduces the demodulation principle of tunable laser power scanning and wavelength feedback control techniques such as wavelength stabilization, frequency stabilization and laser tracking. Most of the existing demodulation techniques are only suitable for single optical channel, and the demodulation frequency is low. The development direction of fiber Bragg grating demodulation technology is multi-channel synchronous stable high frequency demodulation.

Published: July 2022

Abstract
Autonomous driving is an outstanding representative of artificial intelligence, and while it has unlimited opportunities, it also faces unprecedented challenges. The potential risks of autonomous vehicles cause a significant threat to our current traffic system. Multi-sensor data in autonomous vehicles will form scene semantics. When sensors are intruded, however, discordant elements of scene semantics will appear. Anomaly detection of scene semantics can improve the robustness of intrusion detection systems for autonomous driving. In this paper, we proposed a method for scene semantic anomaly detection. We obtain the scene semantic representation by performing a semantic-level fusion of sensor data. Then, to achieve a scene semantic anomaly detection, convert abnormal semantic detection to out-of-distribution detection. To test the effectiveness of our method, we performed experiments on a publicly available dataset of autonomous driving.

Published: July 2022

Abstract
In this paper, a rectangular microwave filter with rectangular groove is designed. The filter adopts symmetrical three-stage structure. The first section is the slot line waveguide section to realize the input / output of microwave signal, the second section is the transition section, which adopts the impedance gradient structure, and the third section is the sspps section composed of periodic symmetrical rectangular groove and 90 degree bending structure. By adjusting the geometric size of the rectangular groove and its air gap, the passband width and stopband characteristics of the filter can be adjusted, and its microwave sub wavelength binding effect can be further improved, making the anti space electromagnetic interference ability of sspps filter more excellent. The filter can be applied to L ∼ s Band civil microwave communication system.
