Comparing masses in literature (CoMaLit) – I. Bias and scatter in weak lensing and X-ray mass estimates of clusters

The first building block to use galaxy clusters in astrophysics and cosmology is the accurate determination of their mass. Two of the most well regarded direct mass estimators are based on weak lensing (WL) determinations or X-ray analyses assuming hydrostatic equilibrium (HE). By comparing these two mass measurements in samples of rich clusters, we determined the intrinsic scatters, $\sigma_\mathrm{WL}\sim$15 per cent for WL masses and $\sigma_\mathrm{HE}\sim$25 per cent for HE masses. The certain assessment of the bias is hampered by differences as large as $\sim$40 per cent in either WL or HE mass estimates reported by different groups. If the intrinsic scatter in the mass estimate is not considered, the slope of any scaling relation `observable--mass' is biased towards shallower values, whereas the intrinsic scatter of the scaling is over-estimated.
The Evaluation of YouTube™ English Videos’ Quality About Coronary Artery Bypass Grafting

Objectives: The aim of the study was to clarify the reliability and quality of English videos about Coronary artery bypass grafting on YouTubeTM. Methods: The study was performed between July 16 and July 30. A cardiovascular surgeon searched for terms including “coronary artery disease,” “coronary artery treatment,” “coronary artery bypass” and “coronary artery bypass surgery,” in YouTubeTM. All videos were classified into two groups according to the source who uploaded the video as professional videos and non-professional videos. Video characteristics including duration of video on YouTube™, length of video, and view numbers for each video were recorded. Moreover, the numbers of “comments,” “likes,” and “dislikes” were noted. Furthermore, the target audience of the videos (professional health care worker and patients) was analyzed, DISCERN score and Global quality score (GQS) were calculated for each video. Results: Totally, 812 videos were divided into two groups according to upload sources; 448 videos were categorized as professional videos and 364 videos were categorized as non-professional videos. The mean number of views was 3220.5 for professional videos and 2216.5 for non-professional videos (p=0.001). In addition, the mean “like” numbers and mean comment numbers were significantly higher for professional videos (p=0.001 and p=0.001). The mean DISCERN score was 2.6 for professional videos and 1.5 for non-professional videos (p=0.001). Similarly, the mean GSQ was significantly higher for professional videos (3.5 vs. 2.5, p=0.001). Conclusion: YouTube™ videos which are shared by professional healthcare workers have better quality and reliability with significantly higher DISCERN score and GQS.
Physics at a future Neutrino Factory and super-beam facility

The conclusions of the Physics Working Group of the International Scoping Study of a future Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried out by the international community between NuFact05, (the 7th International Workshop on Neutrino Factories and Superbeams, Laboratori Nazionali di Frascati, Rome, June 21-26, 2005) and NuFact06 (Irvine, California, 2430 August 2006). The physics case for an extensive experimental programme to understand the properties of the neutrino is presented and the role of high-precision measurements of neutrino oscillations within this programme is discussed in detail. The performance of second generation super-beam experiments, beta-beam facilities, and the Neutrino Factory are evaluated and a quantitative comparison of the discovery potential of the three classes of facility is presented. High-precision studies of the properties of the muon are complementary to the study of neutrino oscillations. The Neutrino Factory has the potential to provide extremely intense muon beams and the physics potential of such beams is discussed in the final section of the report.

Electronic phase separation in the pyrochlore double-exchange model

Electronic phase separation and related inhomogeneity is ubiquitously seen in strongly-correlated systems. A typical example is found between ferromagnetic metal and antiferromagnetic insulator in CMR manganese oxides. Here we demonstrate that the geometrical frustration brings distinctive aspects into the phase separation phenomena. From Monte Carlo simulation and a simple energy comparison for the pyrochlore double-exchange model, we show that such phase separation takes place between ferromagnetic and paramagnetic metals. We discuss the relevance of our results to a spin-glassy metallic phase found in Mo pyrochlore oxides under external pressure.
Factors Influencing Online Purchase Intention among Staff from Royal Malaysian Police (RMP) Headquarters

Online purchase has become a norm in Malaysia after the COVID-19 pandemic. It is one of measures to cope with the rapid spread of the virus. Royal Malaysian Police (RMP) staff are not left behind in following the current trend. The present study is intended to determine the factors that influence them to engage in online purchase although they are very busy in ensuring the public safety. Data were collected using online survey distributed conveniently to the staff. After the lapse of the allocated data collection period, 150 responses were received and analyzed. Out of five factors that have been selected as the independent variables only two are significant to influence online purchase intention among the RMP staff, which are attitude and perceived usefulness. Perceived ease of use, subjective norms, and perceived behavioral control are not significant to influence staff online purchase intention. The findings indicate that only those who have the right attitude towards online purchase and those who find online purchase is beneficial to them will engage in online purchase.
Progress in the Determination of the Partonic Structure of the Proton

We review the state of the art of the determination of the parton substructure of the nucleon, as expressed in terms of parton distribution functions (PDFs) and probed in high-energy lepton–hadron and hadron–hadron collisions. We also assess their implications for current precision collider phenomenology, in particular at the Large Hadron Collider (LHC). We review the theoretical foundations of PDF determination: how cross sections are expressed in terms of PDFs by use of perturbative QCD factorization and evolution, the methodology used to extract PDFs from experimental data, and how different physical processes can be used to constrain different PDFs. We summarize current knowledge of PDFs and the limitations in accuracy that this knowledge currently entails for the computation of hadron collider processes, in particular at the LHC. We discuss the current main sources of theoretical and phenomenological uncertainties and the direction of progress toward their reduction in the future.
MAGNETIC HELICITY REVERSALS IN A CYCLIC CONVECTIVE DYNAMO

We investigate the role of magnetic helicity in promoting cyclic magnetic activity in a global, 3D, magnetohydrodynamic (MHD) simulation of a convective dynamo. This simulation is characterized by coherent bands of toroidal field that exist within the convection zone, with opposite polarities in the northern hemisphere (NH) and southern hemisphere (SH). Throughout most of the cycle, the magnetic helicity in these bands is negative in the NH and positive in the SH. However, during the declining phase of each cycle, this hemispheric rule reverses. We attribute this to a global restructuring of the magnetic topology that is induced by the interaction of the bands across the equator. This band interaction appears to be ultimately responsible for, or at least associated with, the decay and subsequent reversal of both the toroidal bands and the polar fields. We briefly discuss the implications of these results within the context of solar observations, which also show some potential evidence for toroidal band interactions and helicity reversals.
PIERNIK MHD code – a multi–fluid, non–ideal extension of the relaxing–TVD scheme (IV)

We present a new multi-fluid, grid-based magnetohydrodynamics (MHD) code PIERNIK, which is based on the Relaxing Total Variation Diminishing (RTVD) scheme (Jin & Xin 1995). The original scheme (see Trac & Pen 2003 and Pen et al. 2003) has been extended by an addition of dynamically independent, but interacting fluids: dust and a diffusive cosmic ray (CR) gas, described within the fluid approximation, with an option to add other fluids in an easy way. The code has been equipped with shearing-box boundary conditions, a selfgravity module, an Ohmic resistivity module, as well as other facilities which are useful in astrophysical fluid-dynamical simulations. The code is parallelized by means of an MPI library. In this paper we introduce a multifluid extension of the RTVD scheme and present a test case of dust migration in a two-fluid disk composed of gas and dust. We demonstrate that due to the difference in azimuthal velocities of gas and dust and the drag force acting on both components, dust drifts towards maxima of the gas pressure distribution.
The mechanics of a cat landing from a drop

Cats have a remarkable ability to survive drops from great heights. This ability is examined by considering the aerodynamics of the cat during a drop, and by examining the mechanics of the landing. For the landing the spring-like properties of the cat’s legs and the compliance of the landing surface are all modeled. The analysis shows that a combination of the reduction of landing velocity due to aerodynamics, the spring like properties of the cat’s legs, and the relationship between cat mass and bone diameter give cat’s the ability to survive drops from great heights. The analysis highlights how simple models exploiting mechanical principles can explain the survivability of falling cats.
Common-Mode Resonance Suppressing Surface for Tightly Coupled Array

Common-mode resonance in traditional tightly coupled arrays (TCAs) limits bandwidth severely. In this communication, a common-mode resonance suppressing surface (CRSS) is proposed to mitigate the common-mode resonance. The CRSS is a surface etched with slots along the polarized direction placed below the antenna array to replace the ground of traditional TCAs. The CRSS cuts off the surface current on the ground, and thus the common-mode resonance is mitigated. Furthermore, a dual-linear polarized TCA embedded with the CRSS is simulated and manufactured, and the results show that it achieves an impedance bandwidth of 9.3:1 (0.6–5.58 GHz) and more than 90% radiation efficiency for broadside with the active VSWR ≤ 3.0. Besides, such an array remains the same bandwidth while scanning up to 60° in the E- and D-planes and scanning up to 45° in the H-plane with the active VSWR ≤ 3.5. Therefore, the CRSS shows a very promising application in engineering.
Book Reviews: The Form of Information in Science: Analysis of an Immunology Sublanguage

interdisciplinary approach to the analysis of spatial prepositions. The result is an intriguing, sometimes incomplete, often speculative account of how language and space are related. Often the guiding philosophical maxims are contradicted by assumptions made later in the book. For example, the ideal meanings of words often appear to be Platonic objects, something obviously inconsistent with the tenets in the preface of the book. Elsewhere, t he geometric description functions seem to embody mental representations, a view not comfortably condoned by a neo-Heideggerian analysis. In general, however , the work is an enjoyable and well-written foray into a very basic subset of language. Wittgenstein, Ludwig 1963 Philosophical investigations (translated by G. E. Anscombe).

Graduate student diversity, equity and inclusion professional development

Purpose Recent research on graduate students’ diversity, equity and inclusion (DEI) socialization found that graduate colleges play a role in supporting graduate students’ DEI professional development (Perez et al., 2020), but more studies are needed about how graduate colleges facilitate DEI socialization. One graduate college at a large, selective, research-intensive, public university in the Midwestern US created a graduate certificate for professional development in DEI to expand graduate students’ capacities to contribute to inclusion and equity in higher education. The purpose of this multi-method program evaluation is to assess whether the certificate program created significant learning about DEI and developed intercultural competence among graduate students. Design/methodology/approach The authors rely on multiple methods to evaluate the impact of the professional development DEI certificate. First, the authors used the Intercultural Development Inventory (IDI) pre and postassessment to measure the growth of participants in the first three years of the program. Second, the authors designed a reflection tool to assess significant learning after each component of the program. Finally, we conducted focus groups with graduates of the program to understand what program components were most valuable for DEI-related significant learning. Findings The authors found that the DEI professional development program increased students’ intercultural competence as measured by the IDI. Students reported perceptions of significant learning in every domain of learning we assessed using a self-reflection tool and in focus groups. Originality/value To the best of the authors’ knowledge, this is the first study that demonstrates how graduate colleges contribute to DEI socialization by preparing graduate students to interact across differences and contribute to inclusive climates both within and beyond academe.
Elements of Linear and Real Analysis

This is a kind of introduction to some basic topics in analysis, some of which would be covered in standard graduate courses, and some not. However, an important difference is that not much in the way of prerequisites are needed, beyond linear algebra and beginning analysis. In particular, this should be accessible to undergraduates or readers whose main focus is not necessarily pure mathematics. One could easily accommodate Lebesgue integrals and so forth if one wanted to, but they are not really needed.
Current Conveyor Transconductance Amplifier (CCTA) based Grounded Memcapacitor Emulator

A new emulator circuit for designing memcapacitor is proposed in this work. The suggested circuit is designed using a current conveyor transconductance amplifier (CCTA), a memristor and a capacitor. Behaviour of the proposed circuit has been examined for a frequency range of 0.6Hz to 6.4Hz with the help of simulations performed in LTSPICE using TSMC 180nm process parameters. It has been observed that the area inside lobes reduces with increase in frequency. In comparison to other emulators reported in literature, the suggested circuit uses fewer passive components and does not require analog multipliers, thus making it simple to design. The correctness and efficacy of the proposed design are verified using transient analysis, non-volatility analysis, and pinched hysteresis loops.
Machine learning-based simplified methods using shorter wind measuring masts for the time ahead wind forecasting at higher altitude for wind energy applications

Since wind is a fluctuating resource, the integration of wind energy into the electricity grid necessitates precise wind speed forecasting to maintain grid stability and power quality. Machine learning models built on different algorithms are widely used for wind forecasting. This requires a vast quantity of past wind speed data collected at the hub levels of the wind electric machines employed. Tall met masts pose a variety of practical issues in terms of installation and long-term maintenance, which will grow more challenging as next-generation wind turbines come with larger capacities and higher hub heights. In this paper, we propose four non-conventional methods for the time ahead forecasting of wind speed at a higher height by utilizing the wind speed data collected with relatively shorter wind measuring masts. We employ machine learning-based models and rely on the principle of interrelation between wind speeds at different altitudes in our investigations. Wind speed forecasts generated by the new methods at an altitude of 80 m above the ground level using wind speed data measured at lower altitudes of 50 m and 20 m are of industrially acceptable accuracy. The simplified physical requirements such methods demand far outweigh the marginal fall in prediction accuracy observed with these methods.
Molecular Dynamics Simulation on a Metallic Glass Ni$_{0.2}$Zr$_{0.8}$-System: Non-Ergodicity Parameter

At the present paper we have computed non-ergodicity paramater from Molecular Dynamics (MD) Simulation data after the mode-coupling theory (MCT) for a glass transition. MCT of dense liquids marks the dynamic glass-transition through a critical temperature $T_c$ that is reflected in the temperature-dependence of various physical quantities. Here, molecular dynamics simulations data of a model adapted to Ni$_{0.2}$Zr$_{0.8}$ are analyzed to deduce $T_c$ from the temperature-dependence of corresponding quantities and to check the consistency of the statements. Analyzed is the diffusion coefficients. The resulting values agree well with the critical temperature of the non-vanisihing non-ergodicity parameter determined from the structure factors in the asymptotic solution of the mode-coupling theory with memory-kernels in ``One-Loop'' approximation.
Thermally driven domain-wall motion in Fe on W(110)

It has recently been shown that domain walls (DWs) in ferromagnets can be moved in the presence of thermal gradients. In this work we study the motion of narrow domain walls in low-dimensional systems when subjected to thermal gradients. The system chosen is a monolayer of Fe on W(110) which is known to exhibit a large anisotropy while having a soft exchange, resulting in a very narrow domain wall. The study is performed by means of atomistic spin dynamics simulations coupled to first-principles calculations. By subjecting this system to thermal gradients we observe a temperature-dependent movement of the domain wall. The thermal gradient always makes the domain wall move towards the hotter region of the sample with a velocity proportional to the gradient. Our material specific study is complemented by model simulations to discern the interplay between the thermal gradient, magnetic anisotropy, and the exchange interaction and shows that the larger DW velocities are found for materials with broader domain-wall width. The relatively slow DW motion of the Fe/W(110) system is hence primarily caused by its narrow domain-wall width, which results from its large magnetic anisotropy and soft exchange.
Effect of an integrated fly control programme in farrowing houses in Russia on milk yield of sows and growth performance of offspring

The aim of this study was to estimate the efficacy of an integrated fly control programme in farrowing houses on milk yield of sows and growth performance of offspring. Four insecticides: Solfak Duo, Solfak Duo + Baycidal, Quick Bayt, and Agita were tested on 160 sows and 1690 pigs. The effectiveness of these drugs against adult flies ranged from 71.22 to 98.84% and against larvae: from 98.96 to 100%. The results of the studies showed the positive effect of the integrated insecticidal programme for combating adult flies and their larvae in the mother-pig barn on the milk productivity of sows and live weight of piglets. After the combined use of Solfak Duo + Baycidal insecticides a tendency for better results was observed with higher milk production of sows (by 71.1%) and improved live weight of piglets (by 40.6%).
Personality Prediction of Narrative Characters from Movie Scripts

An NLP model that understands stories should 001 be able to understand the characters in them. 002 To support the development of neural models 003 for this purpose, we construct a benchmark, 004 Story2Personality . The task is to pre-005 dict a movie character’s personality based on 006 the narratives of the character in the movie 007 script. Experiments show that our task is chal-008 lenging for the existing text classiﬁcation mod-009 els, as none is able to largely outperform ran-010 dom guesses. We further proposed a multi-011 view model to use both verbal and non-verbal 012 descriptions for personality prediction, which 013 gives improvement compared to using only 014 verbal descriptions. The uniqueness and chal-015 lenges in our dataset call for the development 016 of narrative comprehension techniques from 017 the perspective of understanding characters. 1 018
Ocular Hypotensive Effects of Sacubitril and Valsartan Eye Drops on Ocular Normotensive and Betamethasone-Induced Ocular Hypertensive Rabbits

Background: Glaucoma is a neurodegenerative disorder affecting the eye and is accompanied by elevated intraocular pressure (IOP). Patients may gradually lose their visual field if neglected and even go entirely blind. treatment of glaucoma may in involve surgical, laser therapy, and pharmacological treatment, regarding last, adrenergic agonists, carbonic anhydrase inhibitors, beta-blockers, and other common topical ocular therapies for POAG lower IOP by inhibiting the frequency of AH production or by accelerating AH draining through an unorthodox (uveoscleral) outflow channel (e.g. prostaglandin analogs). Aim of the Study: This present study aimed to explore the efficacy of topically applied sacubatril/valsartan 0.5% eye drop on ocular normotensive and betamethasone-induced ocular hypertensive rabbits. Material and Method: A total of 48 apparently healthy rabbits were included in the present study. They were examined regularly and were kept in a standard laboratory environment. They were provided with fresh water and a diet. The animals were also kept under a light cycle of 12 hours. Animals are equally divided into two major groups the Normotensive group (24 rabbits) and the betamethasone-induced ocular hypertensive group (24 rabbits) each of them is subdivided into four groups each one containing six rabbits.1-vehicle group 20 latanoprost group 3-valsartan group 4-sacubatril/valsartan group The intraocular pressure was measured for both eyes with the aid of a Schiötz tonometer according to the instructions of the manufacturer. The other examined parameters were pupil diameter, light pupillary reflex, corneal sensation reflex, and conjunctival redness. Histopathological examination also will include in this study. Result: this study showed that valsartan is effective in reducing the IOP of both normotensive and betamethasone-induced ocular hypertensive eye meanwhile still not comparable to the latanoprost efficacy. The study also revealed that sacubatril/valsartan causes a significant IOP lowering effect in both groups compared to the vehicle group and also comparable to latanoprost efficacy. Both sacubatril / valsartan and valsartan alone showed more safety profile than latanoprost. Histopathological examination revealed that the level of the Amyloid beta in the retina has no change and so no degenerative changes showed in the macula after 21 days of treatment with sacubatril/valsartan. Conclusion: Sacubitril/valsartan eye drops significantly reduced the IOP with minimum side effects and a clinical trial is required to evaluate its efficacy in the treatment of glaucoma.
