description: Σκοπός: Η ενζυμική θεραπεία υποκατάστασης θεωρείται η ενδεδειγμένη θεραπεία στις βλεννοπολυσακχαριδώσεις. Ωστόσο η επίδρασή της σε καρδιαγγειακές παραμέτρους όπως η μάζα της αριστερής κοιλίας και το κλάσμα εξώθησης δεν έχει μελετηθεί επαρκώς, παρότι η προσβολή του μυοκαρδίου συνδέεται με δυσμενή πρόγνωση. Υλικό και μέθοδοι: Συστηματική ανασκόπηση και μετα – ανάλυση της βιβλιογραφίας στις βάσεις Cochrane Database of Systematic Reviews, MEDLINE και LILACS για μελέτες που αναφέρουν δεδομένα υπερηχογραφικής μελέτης καρδιάς πριν και μετά τη θεραπεία ενζυμικής υποκατάστασης σε ασθενείς με βλεννοπολυσακχαριδώσεις. Αποτελέσματα: Συμπεριλήφθηκαν 14 μελέτες με συνολικά 1061 ασθενείς. Παρατηρήθηκε στατιστικά σημαντική διαφορά στο δείκτη μάζας της αριστερής κοιλίας σε άτομα με έναρξη θεραπείας σε ηλικία μικρότερη των 12 ετών. Στις υπόλοιπες παραμέτρους δε σημειώθηκε στατιστικά σημαντική μεταβολή. Συμπεράσματα: Η ενζυμική θεραπεία υποκατάστασης φαίνεται να συμβάλλει στην υποστροφή της υπερτροφίας της αριστερής κοιλίας, ιδιαίτερα όταν η έναρξη θεραπείας γίνεται σε πρωιμότερη ηλικία
description: Purpose: Enzyme replacement therapy is considered the appropriate treatment for mucopolysaccharidosis. However, its effect on cardiovascular parameters such as left ventricular mass and ejection fraction has not been adequately studied, although cardiovascular disease is associated with an unfavorable prognosis. Materials and methods: Systematic review of the literature in the Cochrane Database of Systematic Reviews, MEDLINE and LILACS for studies reporting cardiac ultrasound data before and after enzyme replacement therapy in patients with mucopolysaccharidosis. Results: The meta- analysis included 14 studies with a total of 1061 patients. There was a statistically significant difference in the left ventricular mass index in subjects who initiated treatment in less than 12 years of age. There was no statistically significant change in the other parameters. Conclusions: Enzyme replacement therapy appears to help reverse left ventricular hypertrophy, especially when treatment is initiated at an earlier age

description: Ionic migration has been proposed as a possible cause of photovoltaic current-voltage hysteresis in hybrid perovskite solar cells. However, a major objection to this hypothesis is that hysteresis can be reduced by changing the interfacial contact materials, which are unlikely to significantly influence the behaviour of ionic defects within the perovskite phase. Here we use transient optoelectronic measurements, combined with device simulations, to show that the primary effects of ionic migration can in fact be observed both in devices with hysteresis, and with hysteresis free type contact materials. The data indicate that electric-field screening, consistent with ionic migration, is similar or identical in both high and low hysteresis CH3NH3PbI3 cells. Simulation of the transients shows that hysteresis requires the combination of both mobile ionic charge and recombination near the contacts. Passivating contact recombination results in higher photogenerated charge concentrations at forward bias which screen the ionic charge, reducing hysteresis.

Assessment of utilization of zinc tablet and ORS among under 5 children with acute diarrhea in Akaki Kality sub- city, Addis Ababa
Creators: name: Hassen, Solomon
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Background: Diarrhea is one of the leading causes of child mortality in under five children. According to the World Health Organization (WHO), an estimated 2.5 billion cases of diarrhea occur among under 5children each year. More than half of the cases occur in Africa and South-East Asia. Diarrhea is a commonly associated problem in children with Zinc deficiency and diarrhea also leads to excess zinc losses. It is anticipated that over one-half of these deaths could be averted through the successful application of zinc as a treatment for childhood diarrhea . According to community based survey, diarrhea is second common cause of under-five mortality (88 per 1000 live births), and morbidity (13%) in Ethiopia. A policy to use zinc to treat children with diarrhoea was adopted by the Ministry of Health of Ethiopia in 2013. Result:-The prevalence of zinc administration is low in developing country. The aim of the study was to assesses zinc and ORS utilization and associated factors in akaki kality sub city, Addis Ababa, Ethiopia. A community based cross-sectional study was done from February 15,2016 to March 15, 2016 . Four hundred twenty two caregivers were included in the study using a house to house interview technique. The data were collected using a structured questionnaire and analyzed using SPSS version 20. Bivariate and multivariate analyses were used to identify the factors related to zinc administration. Two hundred eight three (67.1%) caregivers were administered zinc and ORS. For how long caregivers give Zinc treatment (AOR= 0.069;95%CI:0.006-0.790), reasons for not giving full dose of Zinc (AOR=26.755;95%CI:2.874-249.069), and source of zinc product(AOR=9.301; 95%CI:1.009-85.709) were the factors associated with zinc administration. Conclusions :- 67.1% care givers were administered zinc and ORS to the child for the treatment of diarrhea in this study area. Zinc administration was determined by reasons for not giving full dose of zinc, for how long caregivers give zinc treatment and source of zinc product. In the study area there was low zinc and ORS administration for diarrhea treatments. Recommendations :-Health authority and managers in the study area need to improve the awareness of caregivers in proper utilization of zinc

description: Founded by the late Dr. Arti Hurria, the Cancer and Aging Research Group (CARG) is a collaborative, interdisciplinary team of investigators dedicated to improving the care of older adults with cancer through research, advocacy, and other scholarly initiatives.1 As part of the CARG National Institute on Aging R21/R33 infrastructure grant to harness the available expertise and prioritize the development of high-impact research, the Health Services Research (HSR) Core was developed to foster and advance HSR in geriatric oncology. The mission of the HSR Core is to support clinical investigators to design and conduct highquality HSR focused on older adults with cancer and their caregivers including patterns of care, comparative effectiveness, and care delivery. At the first R21/R33 conference held at City of Hope in October 2018, Dr. Harvey Jay Cohen (Chair, CARG Oversight Board and HSR Core) led the development of this Core. In this perspective paper, we present a review of HSR in geriatric oncology to build a foundation for the Core rationale; proposed Core function, workflow, policies, and procedures; anticipated interactions with other CARG Cores; and proposed plans for sustainability

Heavy inertial particles in rotating turbulence : distribution of particles in flow and evolution of Lagrangian trajectories
Creators: name: Maity, Priyanka
Publisher: name: arXiv
Year: 2023
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: We revisited the problem of heavy particles suspended in homogeneous box turbulence flow subjected to rotation along the vertical axis, which introduces anisotropy along the vertical and horizontal planes. We investigate the effect of the emergent structures due to rotation, on the spatial distribution and temporal statistics of the particles. The spatial distributions were studied using the joint probability distribution function (JPDFs) of the two invariants, $Q$ and $R$, of the velocity gradient tensor. At high rotation rates, the JPDFs of Lagrangian $Q-R$ plots show remarkable deviations from the well known \textit{teardrop} shape. The cumulative probability distribution functions (CDFs) for times during which a particle remains in vortical or straining regions, show exponentially decaying tails except for the deviations at the highest rotation rate. The average residence times of the particles in vortical and straining regions are also affected considerably due to the addition of rotation. In addition, we compute the temporal velocity autocorrelation and connect it to the Lagrangian anisotropy in presence of rotation. The spatial and temporal statistics of the particles are determined by a complex competition between the rotation rate and the heaviness of the particles.

description: Macro/mesopore SiOC ceramic monoliths of anisotropic structure were prepared by freeze casting, using methy phenyl polysiloxane (H44) or methy polysiloxane (MK) and (3-aminopropyl)triethoxysilane (APTES) as precursors. Influence of pyrolysis and testing temperature on compressive strength was investigated. Monoliths pyrolyzed at 700 °C had the highest compressive strength both at 77 K (14.0 ± 4.3 MPa) and 293 K (7.7 ± 1.8 MPa), regardless of precursors. Compressive strength of monolith in parallel direction is around twice as much as perpendicular direction. Compressive strength of both monoliths in liquid nitrogen (77 K) was around twice of that in air (293 K) probably due to low temperature and liquid resistance. Anisotropic expansion was observed, and the shrinkage in parallel direction was almost twice of that in perpendicular direction, which can be verified by the Schapery equation. Monolith made from H44 showed a much higher coefficient of thermal expansion at 77 K than monolith made from MK and APTES, probably due to difference in composition and measurement condition. Thermal conductivities and specific heat capacities displayed an upward trend from low to warmer temperature. The minimum and maximum values for thermal conductivity are 0.2 and 1.2 W m− 1 K− 1. The maximum heat conductivities might be determined mainly by the macroporosity and the thermal conductivity of the hybrid material.

Subsequently, the presentation of key decisions of the CJEU which, initially, from a conservative point of view, favored the automatic application of the principle of mutual recognition of judicial decisions and orders and subsequently, gave a progressive tone by recognizing the possibility of deviation from this principle, when there is a risk of violation of fundamental rights.

description: For experimental investigations of colloid retention in porous media, also denoted as deep bed filtration, X-ray computed microtomography (µCT) has become a basic tool within the last decade. On the one hand, µCT can spatially resolve particle deposition at discrete points of filtration time. On the other hand, the topological information of the porous media including the porosity and the pore size distribution can be obtained. Aside from structural parameters, the velocity field of the fluid within the pores, which cannot be measured by means of µCT, plays an important role in the underlying mechanisms of particle transport and immobilization. In a given structure, a high flow rate will result in increased velocity gradients as well as increased shear forces compared to a lower flow rate. High shear forces are in turn unfavorable for particle deposition. Another imaging modality, magnetic resonance velocimetry (MRV), is capable of quantifying the desired velocity maps. We demonstrate an experimental approach that combines both, MRV and µCT. In contrast to the majority of other investigations about colloid retention, the porous media investigated in this work are monolithic foam-like structures. The evaluation of colloid deposition in those monolithic filters is based on analyzing individual pores. Particle deposition in a pore is expressed by the volumetric fraction of particles while the pore flow is described by the Reynolds number. Results indicate that pores with high Reynolds numbers are not among the pores with the highest or lowest volume fraction of particles for a given time. The particle volume fraction in pores with low Reynolds numbers is mainly a function of the axial position of the pore.
Data Detection in Large Multi-Antenna Wireless Systems via Approximate Semidefinite Relaxation

description: Practical data detectors for future wireless systems with hundreds of antennas at the base station must achieve high throughput and low error rate at low complexity. Since the complexity of maximum-likelihood (ML) data detection is prohibitive for such large wireless systems, approximate methods are necessary. In this paper, we propose a novel data detection algorithm referred to as Triangular Approximate SEmidefinite Relaxation (TASER), which is suitable for two application scenarios: (i) coherent data detection in large multi-user multiple-input multiple-output (MU-MIMO) wireless systems and (ii) joint channel estimation and data detection in large single-input multiple-output (SIMO) wireless systems. For both scenarios, we show that TASER achieves near-ML error-rate performance at low complexity by relaxing the associated ML-detection problems into a semidefinite program, which we solve approximately using a preconditioned forward-backward splitting procedure. Since the resulting problem is non-convex, we provide convergence guarantees for our algorithm. To demonstrate the efficacy of TASER in practice, we design a systolic architecture that enables our algorithm to achieve high throughput at low hardware complexity, and we develop reference field-programmable gate array (FPGA) and application-specific integrated circuit (ASIC) designs for various antenna configurations.

description: We explore the effect magnetic fields have on self-gravitating accretion disks around spinning black holes via numerical evolutions in full dynamical magnetohydrodynamic spacetimes. The configurations we study are unstable to the Papaloizou-Pringle Instability (PPI). PPI-saturated accretion tori have been shown to produce gravitational waves, detectable to cosmological distances by third-generation gravitational wave (GW) observatories. While the PPI operates strongly for purely hydrodynamic disks, the situation can be different for disks hosting initially small magnetic fields. Evolutions of disks without self-gravity in fixed BH spacetimes have shown that small seed fields can initiate the rapid growth of the magneto-rotational instability (MRI), which then strongly suppresses the PPI. Since realistic astrophysical disks are expected to be magnetized, PPI-generated GW signals may be suppressed as well. However, it is unclear what happens when the disk self-gravity is restored. Here, we study the impact of magnetic fields on the PPI-saturated state of a self-gravitating accretion disk around a spinning BH ($χ= 0.7$) aligned with the disk angular momentum, as well as one around a non-spinning BH. We find the MRI is effective at reducing the amplitude of PPI modes and their associated GWs, but the systems still generate GWs. Estimating the detectability of these systems accross a wide range of masses, we show that magnetic fields reduce the maximum detection distance by Cosmic Explorer from 300Mpc (in the pure hydrodynamic case) to 45Mpc for a $10 M_{\odot}$ system, by LISA from 11500Mpc to 2700Mpc for a $2 \times 10^{5} M_{\odot}$ system, and by DECIGO from $z \approx 5$ down to $z \approx 2$ for a $1000 M_{\odot}$ system.
Assessment of Water, Sanitation, and Hygiene (WASH) Facilities among Public and Private General Hospitals in Addis Ababa, Ethiopia
Creators: name: Angasa, Alemu

Year: 2018

description: Background: Globally, many health care facilities lack access to water, sanitation and hygiene; in low and middle income countries, 38% of health care facilities do not have an improved water supply, 19% lack improved sanitation and 35% lack water and soap for hand washing. The Ethiopian national census of healthcare facilities indicated that water coverage 32% and sanitation coverage 85%. Objectives: To assess water, sanitation and hygiene (WASH) facilities among public and private general hospitals in Addis Ababa, Ethiopia, 2017 Methods: A facility based mixed quantitative (descriptive cross-sectional) and qualitative method was conducted on 22 general hospitals in Addis Ababa from 21st April to 15 may of 2017. Convenient total samples of 24 general hospitals were taken for this study. Observation check list for WASH facilities infrastructure and key informant interview guide was used to collect the data for compliance with availability and functionality of WASH facilities. Results: From hospitals included in the study those have flush latrine 4/24 have no running water for OPD toilets and 20/22(90.9%) hospital have no accessible latrine for people with disability. Nine out of 22 hospitals have no separated male and female latrine for OPD patients. Two hospitals have no OPD patient latrine hand washing facility. About 20(36.4%), 66 (55.5%) and 26(78.8%) functional hand washing facility have no soap as cleansing agent for OPD, delivery rooms and pediatric ward patient respectively at study period. Hospital those had hand washing with soap at all washing station was 5/22(22.7%). All hospitals have pipe line water sources in their compound. Conclusion and Recommendation: There is improved sanitation since all hospitals have flush toilet. Twenty (90.9%) hospital lacks accessible toilet for people with disability. There is a gap in soap availability whereas soap coverage at all hand washing facility was at 5/22(22.7%). All hospitals have improved water sources. Availability and accessibility of toilet for people with disability needs improvement.

description: We investigate the total energies of spontaneous spin-valley polarized states in bi-, tri-, and tetralayer rhombohedral graphene where the long-range Coulomb correlations are accounted for within the random phase approximation. Our analysis of the phase diagrams for varying carrier doping and perpendicular electric fields shows that the exchange interaction between chiral electrons is the main driver of spin-valley polarization, while the presence of Coulomb correlations brings the flavor polarization phase boundaries to carrier densities close to the complete filling of the Mexican hat shape top at the Dirac points. We find that the tendency towards spontaneous spin-valley polarization is enhanced with the chirality of the bands and therefore with increasing number of layers.

description: Background: This study further investigates a protective association between oral contraceptive (OC) use and anterior cruciate ligament (ACL) injury noted in prior case-control studies. Methods: Active comparator new user cohort analysis of women aged 13–45 years in the United States from the IBM MarketScan Commercial Claims and Encounters database who newly-initiated low-dose OCs (exposed) or underwent intrauterine device (IUD) insertion (comparison group) from 2000 to 2014. Women were followed for ACL injury starting 90 days after OC initiation or IUD insertion until OC or IUD discontinuation or end of continuous enrollment. Adjusted hazard ratios (adjHR) and 95% confidence intervals (CI) were estimated controlling for age. Secondary analysis replicated previously-published case-control studies assessing “ever” versus “never” OC use over 1- and 5-year periods among women who underwent ACL reconstruction compared to age-matched controls. Results: In the cohort analysis, 2,370,286 women initiated OCs and 621,798 underwent IUD insertion. There were 3571 (0.15%) ACL injuries during an average 370.6 days of continuous OC use and 1620 (0.26%) during an average 590.5 days of IUD use. No difference in risk of ACL injury was observed between OC initiators and IUD users (adjHR = 0.95; 95%CI 0.89, 1.01). The case-control analysis replicated the slight protective association observed in prior studies over a 5-year period (OR = 0.90; 95%CI 0.85, 0.94). Conclusions: This cohort study suggests no association between OC use and ACL injury, while the case-control study suggested bias from uncontrolled confounding and selection factors may have influenced previous findings that suggested a protective association between OC use and ACL injury.

In particular, we calculate the formation probability of one interval in the finite open chain and also formation probability of two disjoint intervals in a finite periodic system. The presented formulas can be also interpreted as the Casimir energy of needles in particular geometries. We numerically check the validity of the exact CFT results in the case of the transverse field Ising chain.

description: Στην παρούσα ερευνητική μελέτη περιγράφεται η ανάπτυξη, βελτιστοποίηση, επικύρωση και εφαρμογή μιας απλής, ειδικής και αξιόπιστης μεθόδου για τον προσδιορισμό της οξειδωμένης γλουταθειόνης (GSSG) σε δείγματα ανθρώπινου σάλιου με την τεχνική της υγρής χρωματογραφίας υψηλής πίεσης σε συνδυασμό με on-line παραγωγοποίηση μετά τη στήλη. Η αναλυόμενη ουσία διαχωρίστηκε από το υπόστρωμα του δείγματος χρησιμοποιώντας μια 100% υδατική κινητή φάση μέσω μιας στήλης αντίστροφης φάσης νέας τεχνολογίας (core-shell). Μετά τη βελτιστοποίηση της αντίδρασης χρησιμοποιώντας πειραματικό σχεδιασμό και επικύρωση Box-Benken, η GSSG ποσοτικοποιήθηκε επακριβώς και εκλεκτικά στην περιοχή των 100–2000 nmol L−1, ενώ το LOD ήταν στα 20 nmol L−1. Η GSSG κατάφερε να ποσοτικοποιηθεί για 15 από τα 20 δείγματα ανθρώπινου σάλιου (75%) με μέση τιμή 860 nmol L−1 (150–4600 nmol L−1). Ο αποκλεισμός της ανηγμένης γλουταθειόνης (GSH) πραγματοποιήθηκε με χρήση Ν-αιθυλομαλεϊμίδιο και εξασφάλισε τη σταθερότητα των δειγμάτων για τουλάχιστον 72 ώρες
description: Glutathione disulfide (GSSG) has been monitored in human saliva samples by an optimized and validated method that is based on liquid chromatography coupled to on-line post column derivatization. The analyte was separated from the sample matrix using a 100% aqueous mobile phase through a core–shell reversed phase column. Following optimization of the reaction using Box- Behnken experimental design and validation, GSSG was quantified accurately and selectively in the range of 100–2000 nmol L−1 with a LOD of 20 nmol L−1. GSSG was quantified in 15 out of 20 human saliva samples (75%) with a mean value of 860 nmol L−1 (150–4600 nmol L−1). Blocking of reduced Glutathione with N-ethylmaleimide ensured stability of the samples for at least 72 h at all temperatures examined

description: Background: Contraceptive use plays an important role in reducing fertility; and at times contraceptive prevalence has been used to evaluate the effect of family planning programs. Quality of family planning services is an important determinant of contraceptive use because it is likely to affect contraceptive adoption and, more significantly, contraceptive continuation i.e. poor access to quality Family Planning services, high discontinuation rate and low motivation to use modern FP methods. Objective; the objective of the study was to determine early discontinuation rate of Implanon and to identify its associated factors among women who ever used implanon in 2012/2013 in Ofla woreda, Tigray, North Ethiopia ,2014 Methods: a community based cross sectional study design with structured and pre tested questionnaires was administered for 244 participants from January 20-March 09, 2014. Six data collectors and two supervisors who were trained on the objective of the study and data collection techniques to administer the questionnaire were recruited in the data collection process. All women who ever used implanon in 2012/2013 were included in the study and the data was collected house to house by taking the list of the participants from the family planning registration book of each Health institutions. The data was entered and cleaned in Epi Info by the principal investigator then exported to SPSS version 20 for analysis. Multivariate Logistic regression was used identify factors associated with early discontinuation of implanon. Result: The mean (±SD) ages of the participants were 26.9±6.9 years. More than half of the participants 168(68.9%) were married, and 199(81.6%) were farmer by occupation. The overall early implanon discontinuation rate in this study was 16% with mean duration of implanon use of 6.6±2.8 months. The main reason for early discontinuation of implanon was Health concerns and side effects followed by desire to have more children. Women who have developed side effects during using of implanon, women who didn't appointed for follow up and women who didn't satisfied by the service given during the implanon insertion were the predictors of early implanon discontinuation. Conclusions: early implanon discontinuation rate in this study was in a considerable number and the main reason for discontinuation was Health concerns. Pre insertion counseling, close monitoring and follow up of implanon users should be made to increase implanon continuation rate

description: We study charged and rotating boson stars in 5-dimensional Einstein-Maxwell(-Chern-Simons) theory assuming the two angular momenta associated to the two orthogonal planes of rotation to be equal. Next to the angular momenta, the boson stars carry electric charge and magnetic moment. Interestingly, we find new branches of Einstein-Maxwell-Chern-Simons solutions for which the spatial part of the gauge potential possesses nodes. Consequently, the magnetic moment and the gyromagnetic ratio have opposite sign as compared to the solutions on the main branch. For sufficiently large energy density we find that the solutions possess ergoregions.

description: The role of defects in van der Waals heterostructures made of graphene and hexagonal boron nitride (h-BN) is studied by a combination of ab initio and model calculations. Despite the weak van der Waals interaction between layers, defects residing in h-BN, such as carbon impurities and antisite defects, reveal a hybridization with graphene p$_{\rm z}$ states, leading to midgap state formation. The induced midgap states modify the transport properties of graphene and can be reproduced by means of a simple effective tight-binding model. In contrast to carbon defects, it is found that oxygen defects do not strongly hybridize with graphene's low-energy states. Instead, oxygen drastically modifies the band gap of graphene, which emerges in a commensurate stacking on h-BN lattices.

description: Although double-peaked narrow emission-line galaxies have been studied extensively in the past years, only a few are reported with the green pea galaxies (GPs). Here we present our discovery of five GPs with double-peaked narrow [OIII] emission lines, referred to as DPGPs, selected from the LAMOST and SDSS spectroscopic surveys. We find that these five DPGPs have blueshifted narrow components more prominent than the redshifted components, with velocity offsets of [OIII]$λ$5007 lines ranging from 306 to 518 $\rm km\, s^{-1}$ and full widths at half maximums (FWHMs) of individual components ranging from 263 to 441 $\rm km\, s^{-1}$. By analyzing the spectra and the spectral energy distributions (SEDs), we find that they have larger metallicities and stellar masses compared with other GPs. The H$α$ line width, emission-line diagnostic, mid-infrared color, radio emission, and SED fitting provide evidence of the AGN activities in these DPGPs. They have the same spectral properties of Type 2 quasars. Furthermore, we discuss the possible nature of the double-peaked narrow emission-line profiles of these DPGPs and find that they are more likely to be dual AGN. These DPGP galaxies are ideal laboratories for exploring the growth mode of AGN in the extremely luminous emission-line galaxies, the co-evolution between AGN and host galaxies, and the evolution of high-redshift galaxies in the early Universe.

description: An analysis of the physics-rich endgame of reionization at $z=5.7$ is performed, utilizing jointly the observations of the Ly$α$ forest, the mean free path of ionizing photons, the luminosity function of galaxies and new physical insight. We find that an upper limit on ${\rm τ_e}$ provides a constraint on the minimum mean free path (of ionizing photons) that is primarily due to dwarf galaxies, which in turn yields a new and yet the strongest constraint on the matter power spectrum on $10^6-10^9M_\odot$ scales. With the latest Planck measurements of ${\rm τ_e = 0.055 \pm 0.009}$, we can place an upper limit of $(8.9\times 10^6, 3.8\times 10^7, 4.2\times 10^8)M_\odot$ on the lower cutoff mass of the halo mass function, or equivalent a lower limit on warm dark matter particle mass ${\rm m_x \ge (15.1, 9.8, 4.6)keV}$ or on sterile neutrino mass ${\rm m_s \ge (161, 90, 33)keV}$, at $(1, 1.4, 2.2)σ$ confidence level, respectively.
