Psychological Exploitation of Pregnant Women During the Covid-19 Pandemic

The spread of COVID-19 globally impacts individuals' fear, stress, and anxiety. This trend is increasing, especially in pregnant women because it belongs to the group at risk to the safety of themselves and their fetuses. This study explores pregnant women's concerns, problems, and attitudes regarding the condition of the outbreak of Covid-19 during the pandemic through detailed and directed discussions based on their respective experiences to be a benchmark for antenatal services by midwives. Method: Data in analysis with qualitative studies. The interview was conducted on 14 pregnant women in Muara Enim Regency of South Sumatra via mobile phone due to social isolation regulations during the Covid-19 pandemic. The result of the analysis of interview content is processed with ten themes, namely: (1) negative emotional states, (2) living with uncertainty (3) changes in routine and social life. (4) concerns about infection, (5) the use of complementary therapies, (6) social support, (7) financial and occupational issues, (8) concerns about birth, (9) antenatal and postnatal services (10) Unclear information. This study shows that the Covid-19 pandemic caused various difficulties, anxiety, and fear, giving rise to various psychological changes in pregnancy. Midwives as antenatal service providers can make the results of this study to modify the special antenatal services of pandemic Covid-19. The service not only focuses on the physical but also prepares the mental health of pregnant women. Collaboration with other health teams becomes necessary to maintain the condition of maternal pregnancy during the Covid-19 Pandemic.

Fermi-Bose mixture with tunable interactions

We give an overview of recent experiments on an ultracold Fermi-Bose quantum gas where the interspecies interaction can be tuned via magnetic Feshbach resonances. We first describe the various steps that have led to the observation of Feshbach resonances in the K-Rb system we investigate, and their accurate characterization. We then describe experiments in which Feshbach resonances are exploited to study interaction effects and to associate weakly bound KRb dimers.
On the ^{}-torsion of elliptic curves and elliptic surfaces in characteristic

We study the extension generated by the x-coordinates of the pe-torsion points of an elliptic curve over a function field of characteristic p. If S → C is a non-isotrivial elliptic surface in characteristic p with a p e -torsion section, then for p e >11 our results imply restrictions on the genus, the gonality, and the p-rank of the base curve C, whereas for p e < 11 such a surface can be constructed over any base curve C. We also describe explicitly all occurring p e in the cases where the surface S is rational or K3 or the base curve C is rational, elliptic or hyperelliptic.
High-dielectric-constant Ta2O5/n-GaN metal-oxide-semiconductor structure

High-dielectric-constant Ta2O5 has been grown on the n-GaN epifilm by rf magnetron sputtering. Photoluminescence measurement has been performed to compare the luminescence intensity with and without the dielectrics. Threefold increase in intensity is obtained, and a surface recombination velocity is estimated to be 3×104 cm/s as an upper limit using a modified dead-layer model. A metal-oxide-semiconductor structure has been fabricated with Al on n-GaN as the ohmic contact and on Ta2O5 as the gate metal. Capacitance-versus-voltage characteristics have been measured. The doping concentration obtained from the depletion regime is compared with the result of Hall measurement, which is 7.0×1016 cm−3. The flat-band voltage is obtained from the high-frequency data, and the effective oxide charge number density is calculated as 4.1×1012 cm−2. Indication of strong inversion appears at low reverse bias due to the high dielectric constant of Ta2O5, and matches closely with calculated values. Hysteresis is observed a.
A corrected semi-proximal ADMM for multi-block convex optimization and its application to DNN-SDPs

In this paper we propose a corrected semi-proximal ADMM (alternating direction method of multipliers) for the general p-block (p 3) convex optimization problems with linear constraints, aiming to resolve the dilemma that almost all the existing modified versions of the directly extended ADMM, although with convergent guarantee, often perform substantially worse than the directly extended ADMM itself with no convergent guarantee. Specifically, in each iteration, we use the multi-block semi-proximal ADMM with step-size at least 1 as the prediction step to generate a good prediction point, and then make correction as small as possible for the middle (p 2) blocks of the prediction point. Among others, the step-size of the multi-block semi-proximal ADMM is adaptively determined by the infeasibility ratio made up by the current semi-proximal ADMM step for the one yielded by the last correction step. For the proposed corrected semi-proximal ADMM, we establish the global convergence results under a mild assumption, and apply it to the important class of doubly nonnegative semidefinite programming (DNN-SDP) problems with many linear equality and/or inequality constraints. Our extensive numerical tests show that the corrected semi-proximal ADMM is superior to the directly extended ADMM with step-size = 1:618 and the multi-block ADMM with Gaussian back substitution [12, 14]. It requires the least number of iterations for 70% test instances within the comparable computing time with that of the directly extended ADMM, and for about 40% tested problems, its number of iterations is only 67% that of the multi-block ADMM with Gaussian back substitution [12, 14].
Design of Low Phase Noise Oscillator Based on SIW Multifunctional Filtering Device

In this brief, an X-band low phase noise oscillator based on the substrate integrated waveguide (SIW) filtering rat-race coupler (FRRC) is proposed. The FRRC in the oscillator design is utilized to act as the frequency-stabilized component, power splitter and matching network simultaneously. It exhibits the merits of high quality factor, high circuit integration and decent impedance matching. For verification, the proposed prototype exploiting an improved SIW FRRC has been investigated, fabricated and measured. It demonstrates that the parallel-feedback oscillator works at 11.03 GHz. The rejection of second and third harmonic signals is up to 49.6 dBc and 48.8 dBc, respectively. In addition, the oscillator exhibits a low phase noise performance of −142.9 dBc/Hz at 1-MHz frequency offset from the oscillation frequency.
Surveying relativistic entanglement of two particles with continuous momenta

In this paper we explore the entanglement of two relativistic spin-$1/2$ particles with continuous momenta. The spin state is described by the Bell state and the momenta are given by Gaussian distributions of product and entangled form. Transformations of the spins are systematically investigated in different boost scenarios by calculating the orbits and concurrence of the spin degree of freedom. By visualizing the behavior of the spin state we get further insight into how and why the entanglement changes in different boost situations.
Rare and Insidious Toxicities from New Combination Therapies in Metastatic Renal Cell Cancer: Lessons Learned from Real-Practice

The advent of immune checkpoint inhibitors in combination with multitarget tyrosine kinase inhibitors has become a standard first-line treatment for metastatic renal cell cancer. Along with survival improvement, new toxicities have emerged. Such adverse events are still complex to be managed and some of them are rare and could be insidious or even fatal. Medical oncologists dispose of guidelines about the management of toxicities from immune checkpoint inhibitors but not for combinations. Therefore, it is still difficult to properly attribute and manage additive or overlapping adverse events. We report two clinical cases regarding rare treatment-related endocrine toxicities—hypophysitis and thyroiditis—with particular focus on their management. To this purpose, immune checkpoint-related toxicities guidelines represent the starting point. However, their implementation with additional measures is needed, considering the increasing complexity of current clinical scenarios. The goal is to correctly recognize adverse events and address side effects, so as not to discontinue effective treatments. We, therefore, aim at discussing the points of proper management of toxicities and individuating potential areas of improvement.
Isinglass Polysaccharides Regulate Intestinal-Barrier Function and Alleviate Obesity in High-Fat Diet Mice through the HO-1/Nrf2 Pathway and Intestinal Microbiome Environment

Plant polysaccharide intervention has shown significant potential to combat obesity. However, studies on animal polysaccharides are indeed rare. The aim of this study was to investigate the potential functions of CIP (IL) on obesity, intestinal microflora dysbiosis, and the possible protection of intestinal barrier in mice fed with high-fat diet (HFD). Our results revealed that after 13 weeks, the HFD+L (high-fat diet + 25 mg/kg CIP) group showed significantly more weight loss and fat accumulation relative to the HFD+H (high-fat diet + 50 mg/kg CIP) group. Furthermore, CIP intervention modulated lipid metabolism and mRNA levels of inflammatory mediators in liver. Overall, CIP clearly improved the intestinal barrier in HFD-fed mice. Additionally, we observed that CIP intervention improved intestinal microbiota community richness and diversity in HFD-fed mice. The CIP intervention mice group showed a relatively low Firmicutes to Bacteroidetes ratio compared to the HFD group. This study concluded that CIP could be used as a functional food to prevent adipocyte accumulation, reduce systemic inflammation, and protect the intestinal barrier.
Evolution of coherence between the Jaynes - Cummings Eigenstates in the presence of repeated occupancy measurements: The case of resonant coupling

A two level system resonantly coupled to a single mode cavity field and subject to ground state occupancy measurement like interaction is considered. For this situation, the solution to the Lindblad master equation for the density matrix is obtained with respect to the Jaynes Cummings eigenstate representation. It is seen that, the rate of decoherence of the superposition of the Jaynes Cummings eigenstates increases monotonically with the increase in the occupancy measurement coupling up to a certain critical value (already reported in the literature in a different context), whereas the rate decreases with the increase in the measurement coupling beyond the same critical value.
Flow facility design and experimental studies of wall-bounded turbulent shear-flows

The presen present thesis spans a range of topics within thearea of turbulent flows, ranging from design of flow facilitiesto evaluation aluation of scaling laws and turbulence modelingdeling aspects through use of experimental data. A newwind-tunnel has been designed, constructed and evaluated at theDept. of Mechanics, KTH. Special attention was directed to thedesign of turning vanes that not only turn the flow but alsoallow for a large expansion without separation in the corners.The investigation of the flow quality confirmed that theconcept of expanding corners is feasible and may besuccessfully incorporated into low turbulence wind-tunnels. Theflow quality in the MTL wind-tunnel at the Dept. of Mechanics,KTH, was as also in investigated confirming that it still isvery good. The results are in general comparable to thosemeasured when the tunnel was as new, with the exception of thetemperature variation ariation that has decreased by a factorof 4 due to an improved cooling system.Experimental data from high Reynolds number zeropressure-gradient turbulent layers have been investigated.These studies have primarily focused on scaling laws withe.g. confirmation of an exponential velocity defect lawin a region, about half the size of the boundary layerthickness, located outside the logarithmic overlap region. Thestreamwise velocity probability density functions in theoverlap region was found to be self-similar when scaled withthe local rms value. Flow structures in the near-wall andbuffer regions were studied ande.g. the near-wall streak spacing was confirmed to beabout 100 viscous length units although the relative influenceof the near-wall streaks on the flow was as found to decreasewith increasing Reynolds number.The separated flow in an asymmetric plane diffuser wasdetermined using PIV and LDV. All three velocity componentswere measured in a plane along the centerline of the diffuser.Results for mean velocities, turbulence intensities andturbulence kinetic energy are presented, as well as forstreamlines and backflow coefficientcien describing theseparated region. Instantaneous velocity fields are alsopresented demonstrating the highly fluctuating flow. Resultsfor the above mentioned velocity quantities, together with theproduction of turbulence kinetic energy and the secondanisotropy inariant are also compared to data from simulationsbased on the k -wformulation with an EARSM model. The simulation datawere found to severely underestimate the size of the separationbubble.Keywords:Fluid mechanics, wind-tunnels, asymmetricdiffuser, turbulent boundary layer, flow structures, PDFs,modeling, symmetry methods.
Thermal Performance of Multilayer PVD Tungsten Coating for the First Wall Application in Nuclear Fusion Devices

The thermal performance of multilayer PVD tungsten and molybdenum coatings on graphite was studied for the application of first wall in nuclear fusion devices. The coatings with a thickness of 5 μm and different numbers of W/Mo layer were prepared and a series of plasma thermal loads from 1.3 to 4.1 MWm-2 was applied. Microstructure changes caused by thermal loadings were analyzed. Scratch test was then conducted to quantify the changes in the adhesion. The microstructural analysis and scratch test results showed that the thermal performance of the coatings varied depending on the degree of heat loads and coating structure. A molybdenum interlayer improved the coating adhesion while the plasma heat resistance of the double-layer W/Mo coating was slightly better than the others.
Implantatens livslängd beroende av stödbehandlingen

T rots att korrekt installerade tand­ implantat förväntas bevara sin funk­ tion länge, visar uppföljnings studier att olika biologiska och/eller meka­ niska komplikationer förekommer hos nästan 40 procent av patienterna redan un­ der de fem första åren efter installationen. Den bakteriella kolonisationen av implantaten kan leda till peri­implantära inflammationer, peri­ implantär mukosit och peri­implantit. Vid peri­ implantär mukosit begränsas inflammationen till angränsande mjukvävnad, medan peri­implantit också orsakar benförlust runt implantaten. På senare tid har insikten vuxit fram att implanta­ tens överlevnad i hög grad beror på god munhy­ gien och regelbunden stödbehandling. Enligt ny forskning förekommer biologiska, inflammato­ riska komplikationer i mindre utsträckning hos sådana patienter som årligen gått på kontroll än hos sådana som uppsökt vård först när kom­ plikationer har uppstått. Det primära målet för stödbehandling av implantat är att förebygga pe­ ri­implantära sjukdomar, eller att behandla dem på ett tidigt stadium, samt att reparera tekniska fel som uppstått i implantatkonstruktionerna. Trots att forskningen inte har presenterat data för hur optimal stödbehandling vid implantat ska genomföras, kan man förmoda att samma princi­ per som gäller för stödbehandling vid parodontit Implantatens livslängd beroende av stödbehandlingen
Prevalence and survival associated with pulmonary hypertension after mitral valve replacement: National echocardiography database of Australia study

Abstract The specific prevalence and outcome of pulmonary hypertension after mitral valve replacement (MVR) is not well documented. The aim of the study was to determine the prevalence and prognostic impact of pulmonary hypertension after MVR. In addition, we sought to determine the threshold of mortality risk according to echocardiography derived pulmonary pressures and those echocardiographic characteristics that are associated with increased mortality. Using the National Echocardiography Database of Australia, patients who had undergone MVR were identified with estimated right ventricular systolic pressure (eRVSP) assessed and linked to patient mortality during mean follow up of 1917 days. Classification and regression tree analysis was used to identify the most powerful predictors of mortality. A total of 10,994 patients who had undergone echocardiography following MVR (mean age 65.2 ± 16, 44.8% women) were studied (mean follow‐up 1917 days). The prevalence of PH (defined as eRSVP ≥40 mmHg) was 64.1% (7042/10,994). Severe PH (eRVSP ≥60 mmHg) was seen in 42.3% (4671/10,994). Mortality in individuals with PH was greater than amongst individuals without PH (41.1% vs. 26.3%). Age, tricuspid regurgitation and left ventricular dysfunction were also associated with mortality. There is a high prevalence of PH after MVR which confers an adverse prognosis. Improved therapeutic approaches to mitral valve disease and the subsequent development of PH are essential.
Real Objects Understanding Using 3D Haptic Virtual Reality for E-Learning Education

: In the past two decades, there has been a lot of work on computer vision technology that incorporates many tasks which implement basic filtering to image classification. The major research areas of this field include object detection and object recognition. Moreover, wireless communication technologies are presently adopted and they have impacted the way of education that has been changed. There are different phases of changes in the traditional system. Perception of three-dimensional (3D) from two-dimensional (2D) image is one of the demanding tasks. Because human can easily perceive but making 3D using software will take time manually. Firstly, the blackboard has been replaced by projectors and other digital screens so such that people can understand the concept better through visualization. Secondly, the computer labs in schools are now more common than ever. Thirdly
Inelastic soliton processes generated by the perturbed KdV equation

Perturbations commonly added to the KdV equation contain terms that represent inelastic interac-tions among KdV solitons in multiple-soliton solutions. These terms trigger the emergence of new waves in the first-order correction to the solution of the perturbed equation. The new waves can represent soliton-anti-soliton creation, annihilation and scattering. Other possible waves represent soliton decay and production.
Chemerin promotes MAPK/ERK activation to induce inflammatory factor production in rat synoviocytes

Chemerin is a chemokine found in adipose tissue that specifically binds to the G protein-coupled receptor, chemokine-like receptor 1, and acts as a chemoattractant for macrophages and dendritic cells. Chemerin levels in the synovial fluid are associated with disease severity in patients with osteoarthritis (OA). However, to the best of our knowledge, the specific mechanism through which chemerin exerts its effects in OA remains unclear. The present study aimed to investigate the underlying mechanism of chemerin-associated synoviocyte inflammation. A Cell Counting Kit-8 assay was used to determine the optimal concentration of chemerin that exerted an effect on the viability of normal rat synoviocytes. The expression levels of MEK/ERK signaling pathway-related marker genes, including MEK, ERK, MMP-3 and MMP-13, were detected using reverse transcription-quantitative PCR. In addition, chemerin-induced phosphorylation of MEK, ERK1/2 and p38 MAPK was analyzed using western blotting, and the production of inflammatory factors following chemerin treatment was determined using ELISA. For the in vivo assessment of the effect of chemerin, Sprague Dawley rats underwent knee surgery to establish an arthritis model. The knee joints were then injected with normal saline or recombinant chemerin, and the synovium and knee joint tissues were harvested for H&E histological observations after 3 weeks. In addition, synovial tissue was analyzed for the production of inflammatory factors by ELISA. The results of the present study revealed that chemerin enhanced the viability of synoviocytes in a dose-dependent manner. The stimulatory effect of chemerin on synoviocytes was shown to be accompanied by the activation of MEK, ERK1/2 and p38 MAPK, which was associated with the production of MMP-13, MMP-3, TNF-α, IL-6 and IL-1β by synoviocytes. Inhibition of the ERK1/2 signaling pathway significantly reduced chemerin-induced MMP-13, MMP-3, TNF-α, IL-6 and IL-1β production. H&E staining showed that synovial hyperplasia and articular cartilage wear were more severe in chemerin treated rats after knee surgery than in knee surgery alone and saline controls. In addition, the articular cartilage surface was damaged, and the synovial tissue showed inflammatory cell infiltration. In Sprague Dawley rats that underwent surgery, but did not receive chemerin treatment, a slight raise in inflammatory cell infiltration and increased levels of inflammatory factors were observed compared with rats that did not undergo surgery; however, Secretion of downstream inflammatory cytokines IL-6, MMP-3, MMP-13, and IL-1β was significantly increased in chemerin treated groups compared with control and chemerin + PD98059 groups. In conclusion, the findings of the present study suggested that chemerin may enhance the production of inflammatory factors in synoviocytes by activating the MEK/ERK signaling pathway.
