Haplotype Assembly Using Manifold Optimization and Error Correction Mechanism

Recent matrix completion based methods have not been able to properly model the haplotype assembly problem for noisy observations. To deal with such cases, we propose a new minimum error correction (MEC) based matrix completion problem over the manifold of rank-one matrices. We then prove the convergence of a specific iterative algorithm to solve this problem. From the simulation results, the proposed method not only outperforms some well-known matrix completion based methods, but also shows a more accurate result compared to a most recent MEC-based algorithm for haplotype estimation.
Permanent Junctional Reciprocating Tachycardia in Infants from Myocarditis-like Presentation to Simple Tachycardia: A Case Series

Permanent Junctional Reciprocating Tachycardia (PJRT) is a rare type of supraventricular tachycardia. It can be misdiagnosed and hence under-treated in infants and children, leading to significant cardiac morbidities and mortalities. We describe four cases of young infants who presented with a wide range of clinical scenarios from neonatal tachycardia to overtly decompensated heart failure, all caused by PJRT. All cases showed complete recovery with appropriate medical treatment. In this case series, we aim to discuss the diversity of clinical presentations, and the challenges surrounding the diagnosis, management, and prognosis. To achieve this aim, we have also performed a detailed literature review and reflected on our cases presented to our center between 2016 to 2020. PJRT is rare; it is often missed or diagnosed late in the presentation. Hence, the key is to keep it in mind in infants presenting with acute cardiac problems from simple tachycardia to a myocarditis-like presentation. Anti-arrhythmic medications are safe and effective as first-line therapy for PJRT in neonates and infants. They can prevent or delay the need for invasive cardiac ablation, which is more challenging in these age groups and should be considered in cases refractory to medical treatment.
Identification of tomato (Solanum lycopersicum) genotype for organic cultivation and better shelf life under North Indian plain condition

A field experiment was laid out in RBD having three replications to investigate the morphological performance, yield and shelf life of five different tomato (Solanum lycopersicum L.) varieties under organic and inorganic ambient. The different tomato varieties behaved significantly different from each other for various growth parameters. The organic ambient grown tomato var. Angoorlata gave the highest plant height, number of branches, leaves and flowers; the variety Pusa Sheetal recorded highest fruit length, fruit diameter, fruit shelf life and fruit yield. The var. Pusa Sheetal also grown inorganic ambient gave highest performance for number of fruits, fruit diameter, fruit weight, shelf life at room temperature and yield production. The potential of the variety Pusa Sheetal for accumulation of higher concentration of soluble solids such as sugars, Vitamin C, polyphenols and best performance for yield contributing attributes as well as highest shelf life at refrigerated condition in organic ambience reflects that it is an eco-health friendly genotype for organic tomato and longer shelf life. This novel finding reported for the first time for the variety Pusa Sheetal opens a new avenue for its larger scientific and practical utility for breeding of new genotypes suitable for organic farming with enhanced shelf life to meet out the increasing fondness and requirement of future consumers.
Omnigenity as Generalized Quasisymmetry

Any viable stellarator reactor will need to be nearly omnigenous, meaning the radial guiding-center drift velocity averages to zero over time for all particles. While omnigenity is easier to achieve than quasisymmetry, we show here that several properties of quasisymmetric plasmas also apply directly or with only minor modification to the larger class of omnigenous plasmas. For example, concise expressions exist for the flow and current, closely resembling those for a tokamak, and these expressions are explicit in that no magnetic differential equations remain. A helicity (M, N) can be defined for any omnigenous field, based on the topology by which B contours close on a flux surface, generalizing the helicity associated with quasisymmetric fields. For generalized quasi-poloidal symmetry (M = 0), the bootstrap current vanishes, which may yield desirable equilibrium and stability properties. A concise expression is derived for the radial electric field in any omnigenous plasma that is not quasisymmetric. T.
Obesity, Diabetes Mellitus, and Metabolic Syndrome: Review in the Era of COVID-19

Coronavirus disease 2019 (COVID-19), a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now at pandemic levels leading to considerable morbidity and mortality throughout the globe. Patients with obesity, diabetes, and metabolic syndrome (MetS) are mainly susceptible and more probably to get severe side effects when affected by this virus. The pathophysiologic mechanisms for these notions have not been completely known. The pro-inflammatory milieu observed in patients with metabolic disruption could lead to COVID-19-mediated host immune dysregulation, such as immune dysfunction, severe inflammation, microvascular dysfunction, and thrombosis. The present review expresses the current knowledge regarding the influence of obesity, diabetes mellitus, and MetS on COVID-19 infection and severity, and their pathophysiological mechanisms.
Maternal and Fetal Outcomes of Preeclampsia With and Without Severe Features in King Abdulaziz University Hospital, Jeddah, Saudi Arabia: A Retrospective Study

Background Preeclampsia is a substantial pregnancy burden that may lead to poor feto-maternal outcomes, particularly in developing countries. It complicates 8% of pregnancies worldwide, resulting in high feto-maternal morbidity and mortality if not appropriately addressed. Despite significant development in obstetric care management in the Kingdom of Saudi Arabia (KSA), prompt recognition of the problem and the necessary care and expertise are vital to tackle this complication. Hence, we studied feto-maternal outcomes in our setting. This study aims to assess the maternal and fetal outcomes of preeclampsia with and without severe features in King Abdulaziz University Hospital (KAUH), Jeddah, KSA. This study aims to identify the maternal and fetal outcomes of preeclampsia among pregnant patients in KAUH, evaluate the role of antepartum follow-up on maternal and fetal outcomes of preeclampsia, and correlate the maternal and fetal complications of preeclampsia. Methodology A retrospective, cross-sectional, hospital-based study was conducted in KAUH, Jeddah, KSA. A total of 83 patients (mean age: 32 ± 6.28) who were admitted with the diagnosis of preeclampsia from 2019 to 2021 were included in the study. Feto-maternal-related outcomes were analyzed in terms of complications. A descriptive statistical method was utilized for the analysis. Results The mean gestational ages where preeclampsia developed with and without severe features were 33.32 weeks and 36 weeks, respectively. There were no significant relationships between preeclampsia and neonatal outcomes. However, there was a significant relationship between preeclampsia with severe features and overall maternal complications without an inclination to a specific complication. Overall, 62% of patients who did not undergo an antenatal follow-up developed preeclampsia with severe features, and 72.2% of these cases were admitted through the emergency department. Conclusions Preeclampsia can have life-threatening effects on both the mother and the fetus; thus, follow-ups and early recognition are recommended to drastically improve morbidity and mortality and provide effective management in line with international and national guidelines to reduce the likelihood of unfavorable outcomes.
On the construction of semisimple Lie algebras and Chevalley groups

Let $\mathfrak{g}$ be a semisimple complex Lie algebra. Recently, Lusztig simplified the traditional construction of the corresponding Chevalley groups (of adjoint type) using the "canonical basis" of the adjoint representation of~$\mathfrak{g}$. Here, we present a variation of this idea which leads to a new, and quite elementary construction of~$\mathfrak{g}$ itself from its root system. An additional feature of this set-up is that it also gives rise to explicit Chevalley bases of $\mathfrak{g}$.
Gaia transient detection efficiency: hunting for nuclear transients

We present a study of the detectability of transient events associated with galaxies for the Gaia European Space Agency astrometric mission. We simulated the on-board detections, and on-ground processing for a mock galaxy catalogue to establish the properties required for the discovery of transient events by Gaia, specifically tidal disruption events (TDEs) and supernovae (SNe). Transients may either be discovered by the on-board detection of a new source or by the brightening of a previously known source. We show that Gaia transients can be identified as new detections on-board for offsets from the host galaxy nucleus of 0.1--0.5,arcsec, depending on magnitude and scanning angle. The Gaia detection system shows no significant loss of SNe at close radial distances to the nucleus. We used the detection efficiencies to predict the number of transients events discovered by Gaia. For a limiting magnitude of 19, we expect around 1300 SNe per year: 65% SN Ia, 28% SN II and 7% SN Ibc, and ~20 TDEs per year.
Status, Challenges and Mitigation Strategies of Production of Non Timber Forest Products in Mundemba Municipality, Southwest Region Cameroon

Land clearing for plantation and settlement establishment has been a prominent driving force for forest ecosystem destruction. This study aimed at evaluating the status, challenges and mitigation strategies of the selected NTFPs produced and Mark¹eted in the study site. This study was carried out in the municipality of Mundemba South West Region Cameroon. Data were collected with the used of open and close ended questionnaires, key informants interviews and field observations. The questionnaires were divided into IV sections. Section I socio-demographic characteristics, section II on the status of the different NTFPs produced and marketed section III on the challenges and section IV on mitigation strategies. Data were subjected to descriptive analyses and were treated using statistical software program IBM SPSS statistics. Chi square Pearson test was used to determine the association. Results showed that 59.00 percent were men while 41.00 percent were women. Based on the IUCN red list categories, 6 of the NTFPs were noticed as least concerned, 4 of the NTFP species are near threatened, while none of the species were noticed to be extinct. The main challenge for production was limited land with 51.00 percent while the least challenge of limited knowledge for production was noticed to 2% and was not significantly different(x2cal = 0.593, x2 table value=0.917). The main challenge for marketing was reported as insecurity with 39 % while the least was failure of buyers to keep to time with 8.00 percent and was significantly different (X2cal= 1.052,x2 table value =0.958). The government strategies for mitigating challenges of production and marketing (x2cal =2.988, x2cal =0.224) was significantly different. The major mitigation of road construction had a percentage of 83.00 percent, while the least noticed for mitigations production and marketing was provision of farm inputs with a percentage of 6 %. Therefore, proper management will definitely lead to improve production and marketing of NTFPs.
A spider-like outflow in Barnard 5 - IRS 1: the transition from a collimated jet to a wide-angle outflow?

We present line and continuum observations made with the Submillimeter Array (SMA) of the young stellar object Barnard 5 - IRS1 located in the Perseus molecular cloud. Our $^{12}$CO(2-1) line observations resolve the high-velocity bipolar northeast-southwest outflow associated with this source. We find that the outflowing gas shows different structures at three different velocity regimes, in both lobes, resulting in a spider-like morphology. In addition to the low-velocity, cone-like (wide-angle) lobes that have previously been observed, we report the presence of intermediate-velocity parabolic shells emerging very close to the Class I protostar, as well as high velocity molecular bullets that appear to be associated to the optical/IR jet emanating from this source. These compact high-velocity features reach radial velocities of about 50 km s$^{-1}$ away from the cloud velocity. We interpret the peculiar spider-like morphology is a result of the molecular material being entrained by a wind with both a collimated jet-like component and a wide-angle component. We suggest the outflow is in a transitional evolutionary phase between a mostly jet-driven flow and an outflow in which the entrainment is dominated by the wide-angle wind component. We also detect 1300 $\mu$m continuum emission at the position of the protostar, which likely arises from the dusty envelope and disk surrounding the protostar. Finally, we report the detection of $^{13}$CO(2-1) and SO(6$_5$-5$_4$) emission arising from the outflow and the location of the young stellar object.
Do radio mini-halos and gas heating in cool-core clusters have a common origin?

In this letter we present a study of the central regions of cool-core clusters hosting radio mini-halos, which are diffuse synchrotron sources extended on cluster-scales surrounding the radio-loud brightest cluster galaxy. We aim to investigate the interplay between the thermal and non-thermal components in the intra-cluster medium in order to get more insights into these radio sources, whose nature is still unclear. It has recently been proposed that turbulence plays a role for heating the gas in cool cores. By assuming that mini-halos are powered by the same turbulence, we expect that the integrated radio luminosity of mini-halos, $\nu P_{\nu}$, depends on the cooling flow power, $P_{\rm CF}$, which in turn constrains the energy available for the non-thermal components and emission in the cool-core region. We carried out a homogeneous re-analysis of X-ray Chandra data of the largest sample of cool-core clusters hosting radio mini-halos currently available ($\sim$ 20 objects), finding a quasi-linear correlation, $\nu P_{\nu} \propto P_{\rm CF}^{0.8}$. We show that the scenario of a common origin of radio mini-halos and gas heating in cool-core clusters is energetically viable, provided that mini-halos trace regions where the magnetic field strength is $B \gg 0.5\, \mu$G .
Studies on Annihilation and Coreactant Electrochemiluminescence of Thermally Activated Delayed Fluorescent Molecules in Organic Medium

Very recently, there is a great research interest in electrochemiluminescence (ECL) featuring thermally activated delayed fluorescence (TADF) properties, i.e., TADF-ECL. It is appealing since the earlier reports in this topic well-confirmed that this strategy has a great potential in achieving all-exciton-harvesting ECL efficiency under electrochemical excitation, which is a breakthrough in the topic of organic ECL. However, organic phase electrochemistry and ECL studies surrounding TADF-ECL are still extremely rare. Especially, the ECL spectra of previous reported TADF emitters are still very different from their PL spectra. In this work, we systematically measure and discuss the liquid electrochemistry and ECL behavior of two typical TADF molecules in organic medium. Most importantly, we verify for the first time that the ECL spectra of them (coreactant ECL mode) are identical to their PL spectra counterparts, which confirms the effectiveness of TADF photophysical properties in the coreactant ECL mode in practice.
KiDS-450: testing extensions to the standard cosmological model

We test extensions to the standard cosmological model with weak gravitational lensing tomography using 450 deg$^2$ of imaging data from the Kilo Degree Survey (KiDS). In these extended cosmologies, which include massive neutrinos, nonzero curvature, evolving dark energy, modified gravity, and running of the scalar spectral index, we also examine the discordance between KiDS and cosmic microwave background measurements from Planck. The discordance between the two datasets is largely unaffected by a more conservative treatment of the lensing systematics and the removal of angular scales most sensitive to nonlinear physics. The only extended cosmology that simultaneously alleviates the discordance with Planck and is at least moderately favored by the data includes evolving dark energy with a time-dependent equation of state (in the form of the $w_0-w_a$ parameterization). In this model, the respective $S_8 = \sigma_8 \sqrt{\Omega_{\rm m}/0.3}$ constraints agree at the $1\sigma$ level, and there is `substantial concordance' between the KiDS and Planck datasets when accounting for the full parameter space. Moreover, the Planck constraint on the Hubble constant is wider than in LCDM and in agreement with the Riess et al. (2016) direct measurement of $H_0$. The dark energy model is moderately favored as compared to LCDM when combining the KiDS and Planck measurements, and remains moderately favored after including an informative prior on the Hubble constant. In both of these scenarios, the dark energy parameters are discrepant with a cosmological constant at the $3\sigma$ level. Moreover, KiDS constrains the sum of neutrino masses to 4.0 eV (95% CL), finds no preference for time or scale dependent modifications to the metric potentials, and is consistent with flatness and no running of the spectral index. The analysis code is publicly available at https://github.com/sjoudaki/kids450
The impact of red noise in radial velocity planet searches: only three planets orbiting GJ 581?

We perform a detailed analysis of the latest HARPS and Keck radial velocity data for the planet-hosting red dwarf GJ581, which attracted a lot of attention in recent time. We show that these data contain important correlated noise component ("red noise") with the correlation timescale of the order of 10 days. This red noise imposes a lot of misleading effects while we work in the traditional white-noise model. To eliminate these misleading effects, we propose a maximum-likelihood algorithm equipped by an extended model of the noise structure. We treat the red noise as a Gaussian random process with exponentially decaying correlation function. Using this method we prove that: (i) planets b and c do exist in this system, since they can be independently detected in the HARPS and Keck data, and regardless of the assumed noise models; (ii) planet e can also be confirmed independently by the both datasets, although to reveal it in the Keck data it is mandatory to take the red noise into account; (iii) the recently announced putative planets f and g are likely just illusions of the red noise; (iv) the reality of the planet candidate GJ581 d is questionable, because it cannot be detected from the Keck data, and its statistical significance in the HARPS data (as well as in the combined dataset) drops to a marginal level of $\sim 2\sigma$, when the red noise is taken into account. Therefore, the current data for GJ581 really support existence of no more than four (or maybe even only three) orbiting exoplanets. The planet candidate GJ581 d requests serious observational verification.
Competing electronic orders on kagome lattices at van Hove filling

The electronic orders in Hubbard models on a kagome lattice at van Hove filling are of intense current interest and debate. We study this issue using the singular-mode functional renormalization group theory. We discover a rich variety of electronic instabilities under short-range interactions. With increasing on-site repulsion $U$, the system develops successively ferromagnetism, intra-unit-cell antiferromagnetism, and charge bond order. With nearest-neighbor Coulomb interaction $V$ alone ($U=0$), the system develops intra-unit-cell charge density wave order for small $V$, $s$-wave superconductivity for moderate $V$, and the charge density wave order appears again for even larger $V$. With both $U$ and $V$, we also find spin bond order and chiral ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}+i{d}_{xy}$ superconductivity in some particular regimes of the phase diagram. We find that the $s$-wave superconductivity is a result of charge density wave fluctuations and the squared logarithmic divergence in the pairing susceptibility. On the other hand, the $d$-wave superconductivity follows from bond order fluctuations that avoid the matrix element effect. The phase diagram is vastly different from that in honeycomb lattices because of the geometrical frustration in the kagome lattice.
Zeros of random linear combinations of entire functions with complex Gaussian coefficients

We study zero distribution of random linear combinations of the form $$P_n(z)=\sum_{j=0}^n\eta_jf_j(z),$$ in any Jordan region $\Omega \subset \mathbb C$. The basis functions $f_j$ are entire functions that are real-valued on the real line, and $\eta_0,\dots,\eta_n$ are complex-valued iid Gaussian random variables. We derive an explicit intensity function for the number of zeros of $P_n$ in $\Omega$ for each fixed $n$. Our main application is to polynomials orthogonal on the real line. Using the Christoffel-Darboux formula the intensity function takes a very simple shape. Moreover, we give the limiting value of the intensity function when the orthogonal polynomials are associated to Szeg\H{o} weights.
Exploring the User Base of Online Neighborhood Networks: Determinants of Online Neighborhood Network Membership and Uses

ABSTRACT This paper aims to determine the prevalence of the use of online neighborhood networks (ONNs) and explores which socio-demographic, socioeconomic status (SES), social integration, and media use determinants predict ONN membership and uses. Drawing on a stratified random sample (Ghent, Belgium), we found that over a third of the population are ONN members and that membership was mainly predicted by socio-demographic characteristics. Also, in contrast to prior research, our results show that ONNs are the local online territory of residents of lower SES, to whom these ONNs are a means of connecting with and capitalizing on neighborhood connections.
