Topological superconductivity of spin-3/2 carriers in a three-dimensional doped Luttinger semimetal

We investigate topological Cooper pairing, including gapless Weyl and fully gapped class DIII superconductivity, in a three-dimensional doped Luttinger semimetal. The latter describes effective spin-3/2 carriers near a quadratic band touching and captures the normal-state properties of the 227 pyrochlore iridates and half-Heusler alloys. Electron-electron interactions may favor non-$s$-wave pairing in such systems, including even-parity $d$-wave pairing. We argue that the lowest energy $d$-wave pairings are always of complex (e.g., $d + i d$) type, with nodal Weyl quasiparticles. This implies $\varrho(E) \sim |E|^2$ scaling of the density of states (DoS) at low energies in the clean limit, or $\varrho(E) \sim |E|$ over a wide critical region in the presence of disorder. The latter is consistent with the $T$-dependence of the penetration depth in the half-Heusler compound YPtBi. We enumerate routes for experimental verification, including specific heat, thermal conductivity, NMR relaxation time, and topological Fermi arcs. Nucleation of any $d$-wave pairing also causes a small lattice distortion and induces an $s$-wave component; this gives a route to strain-engineer exotic $s+d$ pairings. We also consider odd-parity, fully gapped $p$-wave superconductivity. For hole doping, a gapless Majorana fluid with cubic dispersion appears at the surface. We invent a generalized surface model with $\nu$-fold dispersion to simulate a bulk with winding number $\nu$. Using exact diagonalization, we show that disorder drives the surface into a critically delocalized phase, with universal DoS and multifractal scaling consistent with the conformal field theory (CFT) SO($n$)${}_\nu$, where $n \rightarrow 0$ counts replicas. This is contrary to the naive expectation of a surface thermal metal, and implies that the topology tunes the surface renormalization group to the CFT in the presence of disorder.Comment: Published Version in PRB (Editors' Suggestion): 49 Pages, 17 Figures, 3 Table

Total Quality Management System in an Education Environment: The Case of a Private University in Bahrain

The study aims to analyze and explain the effectiveness and efficiency of implementing total quality management principles in private educational institutions. The context of the study narrowed down the areas of comparisons to tutorial conducts, student affairs and infrastructure. A detailed analysis of the existing total quality management currently in place at the selected university was duly comprehended. This resulted in finding the flaws/weaknesses in the system of universities in the kingdom of Bahrain generally. Findings through a survey and interview sessions indicated that teachers were not consulted for any changes in curriculum which leads to a lack of co-operation between management and teachers. Another problem in regards to the total quality management implementation was that students perceived the university as not being concerned with maintenance of the premises. Moreover, student affairs/services section was seriously lacking sport facilities, limited training sessions, poor equipment maintenance

Pin-point effect determination using a rigorous approach

A new method for evaluating the pin-point effect of pile yarn of carpets before weaving has been introduced. The method has been initially accomplished by presenting a standard method for bundle preparation and consequently the pin-point index is presented by image analysis technique. To this end, yarns with different twists are heat set at various times and temperatures. Comparison of the results shows that increasing the twist, time and temperature positively contribute to the pin-point index. In the last section, an adaptive neuro fuzzy model (ANFIS) and an artificial neural network model (ANN) have been designed to predict the pin-point index of the heat set yarns based on training with the experimental data.  The input parameters are twist, time and temperature, and the output is the pin-point index. The results illustrate that the learning capability of the ANFIS model is superior and its generalization ability is slightly better than that of a standalone ANN model

The Effect of Fermentation Time on The Organoleptic Test of Kombucha Tea

Kombucha is a fermented product of sweet tea solution which is added with kombucha starter and scoby. Kombucha culture is a combination of bacteria and yeast called SCOBY (Symbiotic Culture of Bacteria and Yeast). This activity aims to determine the effect of time on the organoleptic test in making kombucha tea. This study used quantitative methods and data collection techniques by conducting organoleptic tests on respondents, in this study using a completely randomized design (CRD). Organoleptic consisting of taste, aroma and color. The results showed that on average all respondents preferred kombucha tea on the 15th day of fermentation. The organoleptic test conducted on 30 respondents had a preference level with the highest percentage for each parameter consisting of 60% taste, 70% aroma and 70% color. Where the longer the fermentation time, the level of preference of the testers for the organoleptic response increases

Muhammadiyah dalam Perkembangan Pendidikan Islam di Indonesia

Muhammadiyah is an organization founded by Kyai Ahmad Dahlan which is mostly engaged in business charities in the field of education such as PAUD/TK, SD, SLTP, SLTA, and Universities. The purpose of this study is to provide a brief review of several research articles that discuss the Muhammadiyah movement from its founding background to its influence in the world of Islamic education in Indonesia. This research method is a literature study because in the end all the material that has been read must be drawn a conclusion in the form of a report. Data sources consist of primary data and secondary data. The results of this study indicate that the emergence of the Muhammadiyah organization is a response to the enforcement of Islamic teachings that depart from the Qur'an and Sunnah. Also of the factors raised from the two studies above are about the purification of monotheism which was influenced by colonialism regarding shirk, superstition, bid'ah and superstition and living in poverty, destitution and ignorance. Muhammadiyah organization is very concerned about the condition of a pluralistic society in the development of the education curriculum in Indonesia

Stress and its associated factors in mothers with preterm infants in a private tertiary care hospital of Karachi, Pakistan

Background: Preterm births are the leading cause of death worldwide. Preterm births not only have devastating effects on the newborn, but they also have psychological effects on the mothers. Identifying stress related to preterm births, and the factors associated with the stress among mothers with preterm infants is of great importance, for providing sound care to the newborns and their mothers. The aim of this protocol paper outlines an extensive approach to assess the level of stress and its associated factors among mothers with preterm infants.Methods: An analytical cross sectional study design will be used to achieve the study objectives. A total of 235 mothers who had given birth to preterm infants will be recruited using consecutive sampling. Data will be collected using a self-developed questionnaire for socio-demographic characteristics, obstetric and gynecological characteristics, marital and familial characteristics, coping related factors and newborns characteristics of mothers with preterm infants. Perceived stress scale (PSS) will also use in the study to identify level of stress among mothers with preterm infants. Data will be analyzed through descriptive and inferential analysis in the Statistical Package for Social Sciences (SPSS) version 22.Conclusion: This study will advance understanding of stress and the variables that influence it in mothers of premature babies. Health care providers would be able to take reference of the current study to conduct interventional studies for the mothers delivering the preterm infants
