Mathematical Analysis of an Atherosclerotic Artery in Presence of Externally Applied Magnetic Field

In general Atherosclerosis is the narrowing of the arteries caused by formation of plaque (fat and calcium) in inner arterial wall. Hardening in inner wall of the arteries restricts the speed of flow in the arteries, which prevents the organs and tissues to get sufficient oxygenated blood for smooth functioning. The characteristics of blood and its flow can deliberate the fundamental understanding with respect to different rheological and haemodynamic properties of blood, which may help in detection and medication of several cardio-vascular, cerebro-vascular and arterial diseases. Many cardio-vascular diseases are caused due to abnormal flow of blood caused by stenosis (tapered segment in local lumen of the inner arterial wall). The arterial turbulence and flow variations are mainly caused by means of unpleasant arterial flow of blood and viscous head losses due to stenosis. The platelets of blood are generally activated by means of very high shear-stresses near stenosis-throat. The induced thrombosis may cause reduced flow velocity of blood flow to the brain and heart. The collective applications of analytical measures and numerical techniques may analyze the problem for more quantifiable investigation. It has been notified to different analytical study that the resistance of flow causes the increase of inner wall skin-friction with simultaneous increase of height of stenosis. Here the character of flow in artery is considered as axi-symmetric in nature. The measure of asymmetrical stenosis found from a mild stenosed artery in threedimensional structure, so that from physiological approach analysis would be more authentic under consideration with the different parameters of flow. According to the rheological parameters the flow model is considered to be Herschel-Bulkley fluid Model. The outcomes connected to Newtonian model of flow are represented as a distinct event of investigations by assuming the suitable values of fluid-index considered as “n”. Blood is characterized as a fluid having electrical conductance, the externally applied magneto hydrodynamic effects are also applied to reduce the flow acceleration of blood in arteries. The analysis is much efficient to explore the collective measures of data information related to phenomena of physiological problem in Atherosclerotic artery.
BR Lupi: Evidence for a High‐Inclination SU Ursae Majoris Starwith Orbital Period 1.91 Hours

We have found cyclic light variations with high amplitude during quiescence possibly reflecting the binary motion of the cataclysmic variable BR Lupi. With this hypothesis, an orbital frequency of 12.573 (1.91 hr) ± 0.071 cycles day−1 is derived. In addition, differential photometry obtained during the 1995 March superoutburst shows superhumps with amplitude 0.25 mag and frequency 12.171 (1.97 hr ) ± 0.106 cycles day−1. Hα emission line radial velocities measured during the decline of the superoutburst follow the orbital motion with half‐amplitude 54 ± 16 km s−1. The mass function along with several empirical and theoretical constraints enabled us to estimate the primary mass M1 = 1.0(1) M⊙, the secondary mass M2 = 0.146(1) M⊙, and the inclination angle (50°
A Ka-Band SLM Printed Filtering Divider-Fed Magnetoelectric Dipole Antenna Array Using Embedded Gap Waveguide

In this letter, a filtering divider-fed magnetoelectric (ME) dipole antenna array using embedded gap waveguide (GW) is investigated. The antenna array is fed by a fifth-order all-resonator 1-to-4 filtering power divider. 4 × 4 ME dipole antennas are excited with the same amplitude and in phase. The selective laser melting and embedded GW technology are employed to reduce fabrication complexity. The measured results show that the proposed antenna array achieves an impedance bandwidth of 27.3–30.8 GHz (|S11| < −10 dB). The gain of the antenna array varies from 19.5 to 20.6 dBi with stable radiation patterns. The advantages of the proper filtering function together with high gain, high efficiency, large power capacity, and compact size in the proposed design ensure a promising future in its applications for millimeter wave radars and communication systems.
Image restorations using a modified relaxed inertial technique for generalized split feasibility problems

In this article, we propose a new efficient self‐adaptive method and prove that it converges strongly to a minimum‐norm solution of a generalized split feasibility problem in real Hilbert spaces. The proposed method is derived from a definite discrete dynamical system in time, which combines both the relaxation and inertial techniques for the purpose of increasing the rate of convergence of the iterative scheme. Furthermore, the method requires the monotonicity and Lipschitz continuity condition of the underlying single‐valued cost operator A$$ A $$ , and it employs some simple self‐adaptive stepsizes that are generated at each iteration by some easy computations. As a by‐product, we obtain methods for solving other classes of generalized split feasibility problems in real Hilbert spaces. Two major merits of our scheme in solving image restoration problems over related schemes are the higher signal‐to‐noise ratio value and lower CPU time for generating recovered images. Finally, we analyze our methods with different related strong convergent methods in the literature.
Reply to the comment on ‘Bootstrap current and neoclassical transport in quasi-isodynamic stellarators’

It is shown that the problem of neoclassical transport at low collisionality in a perfectly quasi-isodynamic (or omnigeneous) stellarator can be reduced to the corresponding problem in a tokamak. In fact, the distribution function consists of two parts: one that can be calculated exactly (for any collision operator) and does not carry any net parallel current and one that is proportional to the total toroidal current and is determined by an equation that is identical to that solved in tokamak theory. Results from the latter can therefore be carried over to the corresponding stellarator situation. Specifically, if the total toroidal current enclosed by a flux surface vanishes, then the net bootstrap current on that surface also vanishes. It is therefore consistent to optimize a stellarator in such a way that the bootstrap current and neoclassical transport are simultaneously minimized.
Electrochemical energy storage and conversion: An overview

Electrochemical energy storage and conversion devices are very unique and important for providing solutions to clean, smart, and green energy sectors particularly for stationary and automobile applications. They are broadly classified and overviewed with a special emphasis on rechargeable batteries (Li‐ion, Li‐oxygen, Li‐sulfur, Na‐ion, and redox flow batteries), electrocatalysts, and membrane electrolytes for fuel cells. The critical challenges for the development of sustainable energy storage systems are the intrinsically limited energy density, poor rate capability, cost, safety, and durability. Albeit huge advancements have been made to address these challenges, it is still long way to reach the energy demand, especially in the large‐scale storage and e‐mobility. A landscape of battery materials developments including the next generation battery technology is meticulously arrived, which enables to explore the alternate energy storage technology. Next generation energy storage systems such as Li‐oxygen, Li‐sulfur, and Na‐ion chemistries can be the potential option for outperforming the state‐of‐art Li‐ion batteries. Also, redox flow batteries, which are generally recognized as a possible alternative for large‐scale storage electricity, have the unique virtue of decoupling power and energy. In this overview, a systematic survey on the materials challenges and a comprehensive understanding of the structure–property–performance relationship of the storage and conversion devices is covered. Further, in‐depth detailing of various catalysts and membrane electrolytes that can be explored as a viable alternative for polymer electrolyte fuel cells as well as direction toward futuristic research areas is highlighted.

Characteristics and timing of mortality in children dying in pediatric intensive care: a 5-year experience

Background Pediatric intensive care units (PICUs), where children with critical illnesses are treated, require considerable manpower and technological infrastructure in order to keep children alive and free from sequelae. Methods In this retrospective comparative cohort study, hospital records of patients aged 1 month to 18 years who died in the study PICU between January 2015 and December 2019 were reviewed. Results A total of 2,781 critically ill children were admitted to the PICU. The mean±standard deviation age of 254 nonsurvivors was 64.34±69.48 months. The mean PICU length of stay was 17 days (range, 1–205 days), with 40 children dying early (<1 day of PICU admission). The majority of nonsurvivors (83.9%) had comorbid illnesses. Children with early mortality were more likely to have neurological findings (62.5%), hypotension (82.5%), oliguria (47.5%), acidosis (92.5%), coagulopathy (30.0%), and cardiac arrest (45.0%) and less likely to have terminal illnesses (52.5%) and chronic illnesses (75.6%). Children who died early had a higher mean age (81.8 months) and Pediatric Risk of Mortality (PRISM) III score (37). In children who died early, the first three signs during ICU admission were hypoglycemia in 68.5%, neurological symptoms in 43.5%, and acidosis in 78.3%. Sixty-seven patients needed continuous renal replacement therapy, 51 required extracorporeal membrane oxygenation support, and 10 underwent extracorporeal cardiopulmonary resuscitation. Conclusions We found that rates of neurological findings, hypotension, oliguria, acidosis, coagulation disorder, and cardiac arrest and PRISM III scores were higher in children who died early compared to those who died later.
Shetland Scots as a new dialect: phonetic and phonological considerations1

The dialect of Scots spoken in the Shetland Islands has been variously described as a language shift variety, acquired when the islanders abandoned their native Norn for Scots from the sixteenth century onwards, or a continuation of the dialects brought to Shetland by Scottish immigrants in the same period. More recently, Millar (2008) discussed the origins of Shetland Scots in a theory of new-dialect formation (Trudgill 2004), which allows for a combination of earlier explanations. In this article, I give a systematic analysis of the phonetics and phonology of Early Shetland Scots in comparison to Norn and mainland Scots dialects. The Shetland Scots data are largely consistent with theoretical expectations, lending further support to the new-dialect reading of the dialect's diachronic development.
Radiative Properties of Patterned Wafers With Nanoscale Linewidth

Temperature nonuniformity is a critical problem in rapid thermal processing (RTP) of wafers because it leads to uneven diffusion of implanted dopants and introduces thermal stress. One cause of the problem is nonuniform absorption of thermal radiation, especially in patterned wafers, where the optical properties vary across the wafer surface. Recent developments in RTP have led to the use of millisecond-duration heating cycle, which is too Short for thermal diffusion to even out the temperature distribution. The feature size is already below 100 nm and is smaller than the wavelength (200-1000 nm) of the flash-lamp radiation. Little is known to the spectral distribution of the absorbed energy for different patterning structures. This paper presents a parametric study of the radiative properties of patterned wafers with the smallest feature dimension down to 30 nm, considering the effects of temperature, wavelength, polarization, and angle of incidence. The rigorous coupled wave analysis is employed to obtain numerical solutions of the Maxwell equations and to assess the applicability of the method of homogeniwtlon based on effective medium formulations.
A k‐ε model for turbulent mixing in shock‐tube flows induced by Rayleigh–Taylor instability

A k‐e model for turbulent mixing induced by Rayleigh–Taylor instability is described. The classical linear closure relations are supplemented with algebraic relations in order to be valid under strong gradients. Calibrations were made against two shock‐tube experiments (Andronov et al. [Sov. Phys. JETP 44, 424 (1976); Sov. Phys. Dokl. 27, 393 (1982)] and Houas et al. [Proceedings of the 15th International Symposium on Shock Waves and Shock Tubes (Stanford U.P., Stanford, CA, 1986)]) using the same set of constants. The new interpretation of the experimental data of Brouillette and Sturtevant [Physica D 37, 248 (1989)], where the mixing length is discriminated from the wall jet, requires a different numerical value for the Rayleigh–Taylor source term coefficient. A detailed physical study is given in both cases. It turns out that the spectrum is narrower in the Brouillette and Sturtevant case than in the Andronov et al. case but the small length scales are of the same magnitude.
The charge and matter distributions of 208Pb

The best available data on the charge and matter distributions of 208Pb are analysed using (a) a Woods-Saxon potential, (b) a Hartree-Fock potential based on Skyrme interactions and (c) a combination of the two, Woods-Saxon for the surface region and Skyrme-Hartree-Fock for the interior. The single-particle energies and tail densities (or RMS radii) of the valence orbitals are also analysed. The agreement between experiment and theory is best for the combined potential.
Evaluation of Internet-Connected Real-Time Remote Auscultation: An Open-Label Randomized Controlled Pilot Trial

The utility of remote auscultation was unknown. This study aimed to evaluate internet-connected real-time remote auscultation using cardiopulmonary simulators. In this open-label randomized controlled trial, the physicians were randomly assigned to the real-time remote auscultation group (intervention group) or the classical auscultation group (control group). After the training session, the participants had to classify the ten cardiopulmonary sounds in random order as the test session. In both sessions, the intervention group auscultated with an internet-connected electronic stethoscope. The control group performed direct auscultation using a classical stethoscope. The total scores for correctly identified normal or abnormal cardiopulmonary sounds were 97/100 (97%) in the intervention group and 98/100 (98%) in the control group with no significant difference between the groups (p > 0.99). In cardiac auscultation, the test score in the control group (94%) was superior to that in the intervention group (72%, p < 0.05). Valvular diseases were not misclassified as normal sounds in real-time remote cardiac auscultation. The utility of real-time remote cardiopulmonary auscultation using an internet-connected electronic stethoscope was comparable to that of classical auscultation. Classical cardiac auscultation was superior to real-time remote auscultation. However, real-time remote cardiac auscultation is useful for classifying valvular diseases and normal sounds.
Enhancement of current-perpendicular-to-plane giant magnetoresistance by insertion of Co50Fe50 layers at the Co2Mn(Ga0.5Sn0.5)/Ag interface

We have investigated the effect of the insertion of Co50Fe50 layers at ferromagnet/spacer interfaces on magnetoresistance (MR) properties in current-perpendicular-to-plane giant MR devices using Co2Mn(Ga0.5Sn0.5) Heusler alloy layers. The insertion of 1 nm thick Co50Fe50 layers led to a large enhancement of MR outputs with a large temperature dependence of MR. Smaller temperature dependences were observed for the insertion of Co50Fe50 layers of thicker than 2 nm, but only with less enhancement of MR outputs.
Bioactive compositions in guava (Psidium guajava) at different stages of maturation in arid conditions

The bioactive compounds, total antioxidant activity and minerals in white, pink and red flesh guava (Psidium guajava L.) varieties were assessed and quantified at three different stages of maturity in arid conditions. Changes in pectin content followed similar trend as fruit firmness and it gradually decreased till ripe stage. Total soluble solids and total sugars increased till full ripe stage but reverse was case for acidity. Ascorbic acid in white flesh guava varieties increased till colour turning stage and then after it decreased, while in coloured varieties it showed decreasing trend till ripe stage. White flesh varieties contains negligible quantity of anthocyanin, lycopene and total carotenoid while pink flesh (Lalit) had highest concentration of these compound followed by red flesh (Red flesh). Total phenols and total antioxidant activities of guava fruits were comparatively low during green mature stage and it increased progressively in later stages. Flesh colour did not show any definite pattern on phenolic content and total antioxidant activities. Phenols was recorded highest in Allahabad Safeda, while total antioxidant activities in Lalit. Stage of maturation showed variable changes in mineral contents in guava varieties. It can be inferred from the present study that the remarkable metabolic changes occur between mature green to colour turning stage.
Immune-Related Gene Signatures to Predict the Effectiveness of Chemoimmunotherapy in Triple-Negative Breast Cancer Using Exploratory Subgroup Discovery

Simple Summary Chemoimmunotherapy combinations have transformed the treatment landscape for patients with triple-negative breast cancer (TNBC). However, the discovery of immune-related biomarkers is needed to optimally identify patients requiring the addition of immune-checkpoint inhibitors (ICIs) to chemotherapy. In this study, we identified immune-related gene signatures via exploratory subgroup discovery algorithm that substantially increase the odds of partial remission for TNBC patients on anti-PD-L1+chemotherapy regimen. We have also uncovered distinct cell populations for TNBC patients with various treatment outcomes. Our framework may result in better risk stratification for TNBC patients that undergo chemoimmunotherapy and lead to overall improvement of their health outcomes in the future. Abstract Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with limited therapeutic options. Although immunotherapy has shown potential in TNBC patients, clinical studies have only demonstrated a modest response. Therefore, the exploration of immunotherapy in combination with chemotherapy is warranted. In this project we identified immune-related gene signatures for TNBC patients that may explain differences in patients’ outcomes after anti-PD-L1+chemotherapy treatment. First, we ran the exploratory subgroup discovery algorithm on the TNBC dataset comprised of 422 patients across 24 studies. Secondly, we narrowed down the search to twelve homogenous subgroups based on tumor mutational burden (TMB, low or high), relapse status (disease-free or recurred), tumor cellularity (high, low and moderate), menopausal status (pre- or post) and tumor stage (I, II and III). For each subgroup we identified a union of the top 10% of genotypic patterns. Furthermore, we employed a multinomial regression model to predict significant genotypic patterns that would be linked to partial remission after anti-PD-L1+chemotherapy treatment. Finally, we uncovered distinct immune cell populations (T-cells, B-cells, Myeloid, NK-cells) for TNBC patients with various treatment outcomes. CD4-Tn-LEF1 and CD4-CXCL13 T-cells were linked to partial remission on anti-PD-L1+chemotherapy treatment. Our informatics pipeline may help to select better responders to chemoimmunotherapy, as well as pinpoint the underlying mechanisms of drug resistance in TNBC patients at single-cell resolution.
Association between psoriasis and coronary artery calcification: A systematic review and meta-analysis

Background Psoriasis and atherosclerosis have overlapping pathophysiological mechanisms. However, the association between psoriasis and coronary artery calcification (CAC), a hallmark of atherosclerosis and a predictor of poor cardiovascular prognosis, remains to be determined. We performed a systematic review and meta-analysis to comprehensively evaluate the association between these related inflammatory conditions. Methods Observational studies evaluating the relationship between psoriasis and CAC were retrieved by searching PubMed, Cochrane’s Library, and Embase databases. Presence of CAC was confirmed according to an Agatston’s Score >0 upon computed tomography examination. A random-effect model incorporating between-study heterogeneity was used to pool the results. Results Sixteen studies involving 3,039 patients with psoriasis and 46,191 controls without psoriasis were included in the meta-analysis. All participants were without previously known cardiovascular diseases. Pooled results showed that psoriasis was associated with overall CAC [odds ratio (OR): 1.54, 95% confidence interval: 1.23–1.91, p < 0.001; I2 = 57%], after matching or adjusting the conventional cardiovascular risk factors. Subgroup analyses showed that study country, comorbidity of psoriatic arthritis, baseline Psoriasis Area and Severity Index, and duration of psoriasis (p for subgroup difference all >0.05) did not significantly affect the association of psoriasis and CAC. However, a stronger association was observed in younger patients (mean age <50 years, OR: 2.63, p < 0.001) compared to older patients (≥50 years, OR: 1.24, p = 0.02; p for subgroup difference <0.001). Conclusion Psoriasis is associated with CAC, and the association may be stronger in younger patients.
Long-Term Radar Observations of the Melting Layer of Precipitation and Their Interpretation

Abstract In this study, 600 h of vertically pointing X-band radar data and 50 h of UHF boundary layer wind profiler data were processed and analyzed to characterize quantitatively the structure and the causes of the radar signature from melting precipitation. Five classes of vertical profiles of reflectivity in rain were identified, with three of them having precipitation undergoing a transition between the solid and liquid phase. Only one of them, albeit the most common, showed a radar brightband signature. In-depth study of the bright band and its dependence on precipitation intensity reveals that the ratio of the brightband peak reflectivity to the rainfall reflectivity is constant at 8 dB below 0.5 mm h−1 and then increases to reach 13 dB at 2.5 mm h−1 and 16 dB at 5 mm h−1. The equivalent reflectivity factor of snow just above the melting layer is on average 1–2 dB below the reflectivity of rain just below the melting layer, independent of precipitation intensity. The classical brightband explanation.
