SYSTEMATIC LITERATURE REVIEW OF JOB SATISFACTION: AN OVERVIEW AND BIBLIOMETRIC ANALYSIS

Job satisfaction is the main variable that must be considered in managing human resource practices. Job satisfaction discusses the extent to which employees are satisfied or dissatisfied with their jobs are caused by several factors that motivate them. This study aims to dig deeper into job satisfaction variable. In achieving this goal, the researchers used a systematic review using PRISMA method and bibliometric analysis techniques which took journals from Science Direct and Emerald during 2017-2022. The results of the screening on the PRISMA method produced 30 (thirty) articles written by 95 (ninety five) authors. Based on the 30 (thirty) articles collected, the results of this study found that there are 4 (four) categories that explain several variables that related to job satisfaction, including leadership, salary, organizational commitment, and job stress. Overall, the research is expected to be the right reference for further research, especially researchers who will examine titles that related to job satisfaction.
Generalized pseudo-coefficients of discrete series of $p$-adic groups

Let $G$ be a connected reductive group over a $p$-adic field $F$ of characteristic 0 and let $M$ be an $F$-Levi subgroup of $G. $ Given a discrete series representation $\sigma$ of $M(F),$ we prove that there exists a locally constant and compactly supported function on $M(F),$ which generalizes a pseudo-coefficient of $\sigma. $ This function satisfies similar properties to the pseudo-coefficient, and its lifting to $G(F)$ is applied to the Plancherel formula.
Rokhlin Property for Group Actions on Hilbert $C^*$-modules

We introduce Rokhlin properties for certain discrete group actions on $C^*$-correspondences as well as on Hilbert bimodules and analyze them. It turns out that the group actions on any $C^*$-correspondence $E$ with Rokhlin property induces group actions on the associated $C^*$-algebra $\mathcal O_E$ with Rokhlin property and the group actions on any Hilbert bimodule with Rokhlin property induces group actions on the linking algebra with Rokhlin property. Permanence properties of several notions such as nuclear dimension and $\mathcal D$-absorbing property with respect to crossed product of Hilbert $C^*$-modules with groups, where group actions have Rokhlin property, are studied. We also investigate a notion of outerness for Hilbert bimodules.
Absolute Parameters for Eight Eclipsing Binaries in the Large Magellanic Cloud: The Mass-Luminosity Relation

A simultaneous light and radial velocity analysis of eight Large Magellanic Cloud (LMC) eclipsing binaries is presented. Combining spectroscopic observations obtained with UVES at the ESO Very Large Telescope and light curves available from the MACHO and OGLE databases, accurate masses and radii for the binary components, along with their spectral types and luminosities, are derived. These determinations allow us to construct the first mass-luminosity relation for late O and early B type stars in the LMC. This mass-luminosity relation looks very similar to that of the Milky Way, in spite of the different metallicities. The good agreement achieved in the comparison with recent theoretical isochrones is encouraging regarding the reliability of star models up to 20 M☉.
Asymptotically periodic piecewise contractions of the interval

We consider the iterates of a generic injective piecewise contraction of the interval defined by a finite family of contractions. Let 0 < δ < ϵ < 1 and let φi : [0, 1] → (0, 1), 1 ⩽ i ⩽ n, be a family of C2 maps whose ranges φ1([0, 1]), ···, φn([0, 1]) are pairwise disjoint and δ < |Dφi(x)| < ϵ for every x ∈ (0, 1). Let 0 < x1<···<xn−1 < 1 and let I1, …, In be a partition of the interval [0, 1) into subintervals Ii having interior (xi−1, xi), where x0 = 0 and xn = 1. Let be the map given by x ↦ φi(x) if x ∈ Ii, for 1 ⩽ i ⩽ n. Among other results we prove that for Lebesgue almost every point (x1, …, xn−1), the piecewise contraction is asymptotically periodic.
Hodge classes and the Jacquet–Langlands correspondence

Abstract We prove that the Jacquet–Langlands correspondence for cohomological automorphic forms on quaternionic Shimura varieties is realized by a Hodge class. Conditional on Kottwitz’s conjecture for Shimura varieties attached to unitary similitude groups, we also show that the image of this Hodge class in $\ell $ -adic cohomology is Galois invariant for all $\ell $ .
UNITARY REPRESENTATIONS FOR THE SCHRODINGER-VIRASORO LIE ALGEBRA

In this paper, conjugate-linear anti-involutions and unitary Harish-Chandra modules over the Schrodinger–Virasoro algebra are studied. It is proved that there are only two classes conjugate-linear anti-involutions over the Schrodinger–Virasoro algebra. The main result of this paper is that a unitary Harish-Chandra module over the Schrodinger–Virasoro algebra is simply a unitary Harish-Chandra module over the Virasoro algebra.
L 2-homology for von Neumann algebras

The aim of this paper is to introduce a notion of L-homology in the context of von Neumann algebras. Finding a suitable (co)homology theory for von Neumann algebras has been a dream for several generations (see [KR71a, KR71b, JKR72, SS95] and references therein). One’s hope is to have a powerful invariant to distinguish von Neumann algebras. Unfortunately, little positive is known about the Kadison-Ringrose cohomology H∗ b (M,M), except that it vanishes in many cases. Furthermore, there does not seem to be a good connection between the bounded cohomology theory of a group and of the bounded cohomology of its von Neumann algebra. Our interest in developing an L-cohomology theory was revived by the introduction of Lcohomology invariants in the field of ergodic equivalence relations in the paper of Gaboriau [Gab02]. His results in particular imply that L-Betti numbers β (2) i (Γ) of a discrete group are the same for measure-equivalent groups (i.e., for groups that can generate isomorphic ergodic measure-preserving equivalence relations). Parallels between the “worlds” of von Neumann algebras and measurable equivalence relations have been noted for a long time (starting with the parallel between the work of Murray and von Neumann [MvN] and that of H. Dye [Dy]). Thus there is hope that an invariant of a group that “survives” measure equivalence will survive also “von Neumann algebra equivalence”, i.e., will be an invariant of the von Neumann algebra of the group. The original motivation for our construction comes from the well understood analogy between the theory of II1-factors and that of discrete groups, based on the theory of correspondences [Con, Con94]. This analogy has been remarkably efficient to transpose analytic properties such as “amenability” or “property T” from the group context to the factor context [Con80] [CJ] and more recently in the breakthrough work of Popa [Popa] [Con03]. We use the theory of correspondences together with the algebraic description of L-Betti numbers given by Luck. His definition involves the computation of the algebraic group homology with coefficients in the group von Neumann algebra. Following the guiding idea that the category of bimodules over a von Neumann algebra is the analogue of the category of modules over a group, we are led to the following algebraic definition of L-homology of a von Neumann algebra M :
X-ray magnetic circular dichroism on Co monodispersive cluster assemblies

X-ray absorption near edge structure (XANES) spectra and x-ray magnetic circular dichroism (XMCD) spectra at the Co K edge have been measured for Co clusters with the mean diameter d = 6-13 nm. The spectral analysis indicates that the fcc phase is predominant for d = 6 nm, while the hcp phase gradually increases with increasing d in agreement with the results of transmission electron microscopy. The 4p orbital moments of clusters tend to decrease in the smaller cluster, but the reduction is small compared with the case of the multilayers, suggesting the importance of surface effects of the Co cluster system.
Mechanical Characterization of Two-Segment Free-Standing ZnO Nanowires Using Lateral Force Microscopy

Mechanical characterization of quasi one-dimensional nanostructures is essential for the design of novel nanoelectromechanical systems. However, the results obtained on basic mechanical quantities, such as Young’s modulus and fracture strength, show significant standard deviation in the literature. This is partly because of diversity in the quality of the nanowire, and partly because of inappropriately performed mechanical tests and simplified mechanical models. Here we present orientation-controlled bending and fracture studies on wet chemically grown vertical ZnO nanowires, using lateral force microscopy. The lateral force signal of the atomic force microscope was calibrated by a diamagnetic levitation spring system. By acquiring the bending curves of 14 nanowires, and applying a two-segment mechanical model, an average bending modulus of 108 ± 17 GPa was obtained, which was 23% lower than the Young’s modulus of bulk ZnO in the [0001] direction. It was also found that the average fracture strain and stress inside the nanowire was above 3.1 ± 0.3 % and 3.3 ± 0.3 GPa, respectively. However, the fracture of the nanowires was governed by the quality of the nanowire/substrate interface. The demonstrated technique is a relatively simple and productive way for the accurate mechanical characterization of vertical nanowire arrays.
LRST model movable trevis: A novel method to restrain cattle in barns

Appropriate and humane method of restraining the animals is essential to perform any type of clinical examination especially during the use of modern diagnostic equipments like ultrasound scanner. Procedures involving repeated screening of more number of animals make it difficult to move them for restraining in fixed facilities like chute/trevis outside the barn. The ongoing research project on impact of thermal stress on fertility of cows involve ultrasound scanning, blood collection and other observations on many cows almost every day over a period of one year and necessitate repeated restraining. Hence, the idea of fabricating a convenient movable trevis to restrain cows within the barns was initiated and the final device developed through step by step improvisation was named as LRST model trevis. The trevis could be rolled within the barn to enclose the animal in its standing space and was fixed in situ using the facilities provided. The removable metal tray was used for placing the ultrasound scanner/other equipments in a safe and convenient position. The trevis on wheels was found to be very useful for transrectal ultrasound scanning and other procedures as it causes minimum stress to the animal, comfortable for the examiner, trouble free for the helpers, ensures safety and cleanliness of the machine, time saving and facilitates more effective diagnostic intervention. Hence, the LRST model movable trevis can be adopted with minor changes to suit individual farms for convenient handling and clinical examination especially ultrasound scanning of large ruminants within the barns.
Superassociations as Part of a Fractal Hierarchy

We show that the correlation between the size of the largest superassociations and the luminosity of the parent galaxy found by Elmegreen et al. is most likely due to the size-of-sample effect acting on a universal size distribution. We calculate this distribution function to be dN ∝ r-4.2±0.6dr, independent of the luminosity of the parent galaxy, and show that this law is consistent with the hypothesis that superassociations are part of a fractal hierarchy of structures that might extend from stellar-sized clouds all the way to full galaxies.
One-dimensional and two-dimensional generalised discrete fourier transforms

One-dimensional and two-dimensional generalized discrete Fourier transforms (GFT) are introduced. If a one-dimensional vector A is fractured into a two-dimensional matrix B, a one-dimensional GFT on A and a two-dimensional GFT on B give the same result and require the same number of operations to be computed. The result holds also for the DFT, as it is a particular case of the GFT.
Bootstrap Percolation on the Hamming Torus

The Hamming torus of dimension $d$ is the graph with vertices $\{1,\dots,n\}^d$ and an edge between any two vertices that differ in a single coordinate. Bootstrap percolation with threshold $\theta$ starts with a random set of open vertices, to which every vertex belongs independently with probability $p$, and at each time step the open set grows by adjoining every vertex with at least $\theta$ open neighbors. We assume that $n$ is large and that $p$ scales as $n^{-\alpha}$ for some $\alpha>1$, and study the probability that an $i$-dimensional subgraph ever becomes open. For large $\theta$, we prove that the critical exponent $\alpha$ is about $1+d/\theta$ for $i=1$, and about $1+2/\theta+\Theta(\theta^{-3/2})$ for $i\ge2$. Our small $\theta$ results are mostly limited to $d=3$, where we identify the critical $\alpha$ in many cases and, when $\theta=3$, compute exactly the critical probability that the entire graph is eventually open.
Classification of tight $C^{*}$-algebras over the one-point compactification of $\mathbb{N}$

We prove a strong classification result for a certain class of $C^{*}$-algebras with primitive ideal space $\widetilde{\mathbb{N}}$, where $\widetilde{\mathbb{N}}$ is the one-point compactification of $\mathbb{N}$. This class contains the class of graph $C^{*}$-algebras with primitive ideal space $\widetilde{\mathbb{N}}$. Along the way, we prove a universal coefficient theorem with ideal-related $K$-theory for $C^{*}$-algebras over $\widetilde{\mathbb{N}}$ whose $\infty$ fiber has torsion-free $K$-theory.
Recovery of Methanol during Natural Gas Dehydration Using Polymeric Membranes: Modeling of the Process

A significant proportion of natural gas (NG) is produced in cold climates, where conditions are relevant to the formation of gas hydrates in raw gas stream. Methanol is often used as an effective inhibitor of hydrate formation. Further conditioning of NG includes dehydration, and the most common process of water vapor removal from NG is absorption. Absorption also provides removal of methanol vapors, which allows it reuse. The membrane method of natural gas dehydration is considered as a promising alternative; however, the study of methanol recovery by the membrane method, simultaneously to the dehydration of NG, has not been carried out previously. In addition, data on methanol vapor transfer in gas separation polymer membranes are almost absent in the literature. This paper evaluates the permeability coefficients of methanol vapors for several polymer materials, which are applied to the production of industrial membranes (PPO, PSf, CA). Mathematical modeling of the membrane process of NG dehydration with simultaneous recovery of methanol was performed. The dependencies of membrane area, methanol recovery and energy consumption for methane recycling and recompression on the process parameters are calculated. Obtained data show that the recovery of methanol during membrane dehydration of NG varies in the range 57–95%. The lowest values of membrane area and specific energy consumption were found for PPO based membrane.
A Hybrid Method of Combinatorial Search and Coordinate Descent for Discrete Optimization

Discrete optimization is a central problem in mathematical optimization with a broad range of applications, among which binary optimization and sparse optimization are two common ones. However, these problems are NP-hard and thus difficult to solve in general. Combinatorial search methods such as branch-and-bound and exhaustive search find the global optimal solution but are confined to small-sized problems, while coordinate descent methods such as coordinate gradient descent are efficient but often suffer from poor local minima. In this paper, we consider a hybrid method that combines the effectiveness of combinatorial search and the efficiency of coordinate descent. Specifically, we consider random strategy or/and greedy strategy to select a subset of coordinates as the working set, and then perform global combinatorial search over the working set based on the original objective function. In addition, we provide some optimality analysis and convergence analysis for the proposed method. Our method finds stronger stationary points than existing methods. Finally, we demonstrate the efficacy of our method on some sparse optimization and binary optimization applications. As a result, our method achieves state-of-the-art performance in terms of accuracy. For example, our method generally outperforms the well-known orthogonal matching pursuit method in sparse optimization. Keywords: Sparsity Optimization, Binary Optimization, Coordinate Descent, Combinatorial Search, Discrete Optimization, Convergence Analysis.
The spectral radius of graphs without trees of diameter at most four

Nikiforov [The spectral radius of graphs without paths and cycles of specified length. Linear Algebra Appl. 2010;432(9):2243–2256] conjectured that for a given integer k, any graph G of sufficiently large order n with spectral radius contains all trees of order 2k+2, unless , where denotes the join of a complete graph of order k and an empty graph of order n−k. In this article, we show that the conjecture is true for trees of diameter at most four, more specifically, we prove that, for and , every graph G of order n with contains all trees T of order 2k+2 and of diameter at most four as a subgraph, unless .
Cellular Probabilistic Automata - A Novel Method for Uncertainty Propagation

We propose a novel density based numerical method for uncertainty propagation under distinct partial differential equation dynamics. The main idea is to translate them into objects that we call cellular probabilistic automata and to evolve the latter. The translation is achieved by state discretization as in set oriented numerics and the use of the locality concept from cellular automata theory. We develop the method using the example of initial value uncertainties under deterministic dynamics and show that it is consistent. As an application we discuss arsenate transportation and adsorption in drinking water pipes and compare our results to Monte Carlo computations.
Carroll versus Newton and Galilei: two dual non-Einsteinian concepts of time

The Carroll group was originally introduced by Lévy-Leblond (1965 Ann. Inst. Henri Poincaré 3 1) by considering the contraction of the Poincaré group as c → 0. In this paper an alternative definition, based on the geometric properties of a non-Minkowskian, non-Galilean but nevertheless boost-invariant, spacetime structure is proposed. A ‘duality’ with the Galilean limit c → ∞ is established. Our theory is illustrated by Carrollian electromagnetism.
A Real Nullstellensatz for Matrices of Non-Commutative Polynomials

This article extends the classical Real Nullstellensatz to matrices of polynomials in a free $\ast$-algebra $\RR\axs$ with $x=(x_1, \ldots, x_n)$. This result is a generalization of a result of Cimpri\vc, Helton, McCullough, and the author. In the free left $\RR\axs$-module $\RR^{1 \times \ell}\axs$ we introduce notions of the (noncommutative) zero set of a left $\RR\axs$-submodule and of a real left $\RR\axs$-submodule. We prove that every element from $\RR^{1 \times \ell}\axs$ whose zero set contains the intersection of zero sets of elements from a finite subset $S \subset \RR^{1 \times \ell}\axs$ belongs to the smallest real left $\RR\axs$-submodule containing $S$. Using this, we derive a nullstellensatz for matrices of polynomials in $\RR\axs$. The other main contribution of this article is an efficient, implementable algorithm which for every finite subset $S \subset \RR^{1 \times \ell}\axs$ computes the smallest real left $\RR\axs$-submodule containing $S$. This algorithm terminates in a finite number of steps. By taking advantage of the rigid structure of $\RR\axs$, the algorithm presented here is an improvement upon the previously known algorithm for $\RR\axs$.
Trees, homology, and automorphism groups of RAAGs

We study the homology of an explicit finite-index subgroup of the automorphism group of a partially commutative group, in the case when its defining graph is a tree. More concretely, we give a lower bound on the first Betti number of this subgroup, based on the number and degree of a certain type of vertices, which we call deep. We then use combinatorial methods to analyze the average value of this Betti number, in terms of the size of the defining tree.
Ray perturbation theory and the Born approximation

SUMMARY Ray perturbation theory and the Born approximation have both been used extensively in seismological studies to describe the effects of a slowness perturbation on body and surface wavefields. The relationship between the expressions for the perturbed wavefield calculated using the two methods is investigated here. Using the symplectic symmetry of the ray equations we demonstrate the agreement, in the far field, of the two methods to first order in the slowness perturbation and to leading order in the asymptotic ray series. Thus it is shown that geometrical ray effects, like the traveltime perturbation, ray bending and focusing, are contained within the Born scattering formalism, provided these effects are small. The propagator formalism used to present the results is sufficiently general to include body and surface waves with a smoothly varying inhomogeneous elastic reference medium.
Short- and Long-Term Effects of Different Antibiotics on the Gut Microbiota and Cytokines Level in Mice

Background Antibiotics are the first line of treatment for infectious diseases. However, their overuse can increase the spread of drug-resistant bacteria. The present study analyzed the impact of different types of antibiotics on the gut microbiome and cytokines level of mice. Methods A total of five groups of 8-week-old male BALB/c mice (n = 35) were treated with piperacillin-tazobactam (TZP), ceftriaxone (CRO), tigecycline (TGC), levofloxacin (LEV) or normal saline (Ctrl), respectively, for up to 4 weeks. Fecal samples were analyzed by bacterial 16S rRNA gene sequencing for bacterial identification. Blood samples were used for the determination of 23 serum cytokines using multiplex immunoassay. Results Exposure to antibiotics was shown to affect the normal weight gain of mice. Significant changes in gut composition caused by TZP, CRO and TGC treatment included the decreased abundance of Bacteroidetes (p < 0.01), Muribaculaceae (p < 0.01) and Lachnospiraceae (p < 0.01), and the increased abundance of Proteobacteria (p < 0.05), Enterobacteriaceae (including Klebsiella and Enterobacter) (p < 0.01) and Enterococcaceae (including Enterococcus) (p < 0.01). After 4-week treatment, the TZP, CRO and LEV groups had significantly lower concentrations of several serum cytokines. Correlation analysis of the top 30 bacterial genera and cytokines showed that Enterococcus and Klebsiella were strongly positively correlated with tumor necrosis factor-α (TNF-α), interleukins (IL) IL-12p70 and IL-1β. Desulfovibrio, Candidatus Saccharimonas, norank_f__norank_o__Clostridia_UCG-014, Lactobacillus, and Roseburia were strongly negatively correlated with these cytokines. Conclusion This study demonstrates the effects of various antibiotics on the intestinal microflora and immune status of mice. Compared with TZP, CRO and TGC, LEV had minimal impact on the gut microbiota. In addition to TGC, long-term TZP, CRO and LEV intervention can lead to a decrease in serum cytokine levels, which may depend on the intestinal microflora, antibiotic used and the duration of treatment.
