University Cats? Predictors of Staff and Student Responsiveness Toward On-Campus Cat Visitations

ABSTRACT As most university-based animal-assisted interventions (AAIs) feature interactions with dogs, little is known about the feasibility of providing opportunities to interact with cats. Few studies have examined employee or student interest in interacting with on-campus cats, and virtually nothing is known about the role of participants’ characteristics and perceptions in shaping their interest. Using a cross-sectional survey, the current study assessed participants’ responsiveness toward an on-campus cat visitation program in a sample of higher-education staff and students (n = 1,438). Using hierarchical regression analyses, responsiveness was modeled on participants’ demographic characteristics (i.e., employee or student, gender, age), the personality trait of emotionality, perceived stress, prior animal experiences (i.e., cat/dog ownership, cat allergy and phobia, responsiveness toward on-campus dogs), and perceived risks of on-campus cats. Regression analyses indicated that emotionality (β = 0.15, p < 0.001), being female (β = 0.06, p < 0.05), being open to a dog visitation program (β = 0.50, p < 0.001), and being a cat owner (β = 0.13, p < 0.001), were positively associated with responsiveness toward a cat visitation program, whereas having a cat phobia (β = −0.22, p < 0.001), cat allergy (β = −0.13, p < 0.001), being a dog owner (β = −0.08, p < 0.001), and perceiving interactions with cats as risky (β = −0.14, p < 0.001) were negatively associated. Interestingly, although we hypothesized positive associations between perceived stress and responsiveness, these associations were not significant (β = −0.03, p = 0.305), nor did we observe significant differences by student or employee status (β = 0.02, p = 0.610). These findings are the first to elucidate the role of staff and students’ features in shaping responsiveness toward on-campus cats in higher education, which may inform the design and implementation of on-campus visitation programs.
Fungal Infection: A Recent Concern for Physician

Fungal diseases are an important determinant of survival in immunocompromised patients and in patients with chronic illnesses. Fungal infections in Bangladesh are diverse, and many studies have documented their frequency. A better understanding of the epidemiology, clinical features, and diagnostic method of fungal infection is integral to improving outcomes. In this review, we discuss the emergence of fungal infection along with the clinical pictures, diagnosis, and treatment of different fungal infections that are prevalent in our country. It is hoped that this article will create greater awareness of the burden of fungal infections on public health and promote effective diagnosis and therapy. Bangladesh J Medicine 2022; 33: 235-240
The Genetic Algorithm (GA) in Relation to Natural Evolution

For optimizing search global solution for complicated issues the Genetic Algorithm (GA) is a famous evolutionary computation technique that plays an important role in finding meaningful solutions to hard problems with a huge search space could be a process based on genetic selection ideas. In addition, it supports machine learning causes, as well as study and evolution. However, developing genetic processes that were formerly significant to a random population, which might be started by biology for chromosomal production with factors like selection, crossover, and mutation. The aim of going through this GA process is to find a solution for consecutive generations. In individual production there has been an extent success instantly in ratio to fitness which is suited for it, as a result successive generation will be better in one condition, which is ensuring the quality. Furthermore, John Holland is considered as being the funding father of the initial genetic algorithm, with a funding date in the 1970s. in this paper we have explained what a genetic algorithm is, its key operations, and how it works as well as its features and applications.
Residual wavefront control of segmented mirror telescopes

Uncorrected residual wavefront errors limit the ultimate performance of adaptive optics (AO) systems. We present different contributing factors and techniques to estimate and compensate these wavefront errors in the Keck natural guide star (NGS) AO systems. The error terms include low order static and semi-static aberrations from multiple sources, periodic and random segment piston errors, single-segment low order aberrations, wavefront sensor aliasing, vibrations, calibration drifts, and AO-to-telescope offload related errors. We present the design of a new AO subsystem, a residual wavefront controller (rWFC) to monitor the performance of the AO control loops and the image quality of the AO science instruments and apply the necessary changes to the telescope and AO parameters to minimize the residual wavefront errors. The distributed system consists of components at the telescope, AO bench and the science instruments. A few components of this system are already tested as on-demand standalone tools and will be integrated into a high-level graphical user interface (GUI) to operate the system. The software tool will periodically collect AO telemetry data, perform control loop parameter optimization and update AO parameters such as loop gains, centroid gain, etc. In addition, the system will analyze the science data at the end of each exposure and estimate telescope/AO performance when a bright point source is available in the science field. The benefits of reducing or eliminating the residual wavefront errors have broad implications for optical astronomy. Testing these techniques on a segmented telescope will be extremely useful to the teams developing high contrast AO systems for all extremely large telescopes and future segmented space telescopes.
Principal component and second generation wavelet analysis of treasury yield curve evolution

OF THE DISSERTATION PRINCIPAL COMPONENT AND SECOND GENERATION WAVELET ANALYSIS OF TREASURY YIELD CURVE EVOLUTION by Mark L. Copper Florida International University, 2004 Miami, Florida Professor Joel R. Barber, Major Professor Prices of U.S. Treasury securities vary over time and across maturities. When the market in Treasurys is sufficiently complete and frictionless, these prices may be modeled by a function time and maturity. A cross-section of this function for time held fixed is called the yield curve; the aggregate of these sections is the evolution of the yield curve. This dissertation studies aspects of this evolution. There are two complementary approaches to the study of yield curve evolution here. The first is principal components analysis; the second is wavelet analysis. In both approaches both the time and maturity variables are discretized. In principal components analysis the vectors of yield curve shifts are viewed as observations of a multivariate normal distribution. The resulting covariance matrix is diagonalized; the resulting eigenvalues and eigenvectors (the principal components) are used to draw inferences about the yield curve evolution. In wavelet analysis, the vectors of shifts are resolved into hierarchies of localized fun­ damental shifts (wavelets) that leave specified global properties invariant (average change and duration change). The hierarchies relate to the degree of localization with movements restricted to a single maturity at the base and general movements at the apex. Second generation wavelet techniques allow better adaptation of the model to economic observ­ ables. Statistically, the wavelet approach is inherently nonparametric while the wavelets themselves are better adapted to describing a complete market. Principal components analysis provides information on the dimension of the yield curve process. While there is no clear demarkation between operative factors and noise, the top six principal components pick up 99% of total interest rate variation 95% of the time. An economically justified basis of this process is hard to find; for example a simple linear model will not suffice for the first principal component and the shape of this component is nonstationary. Wavelet analysis works more directly with yield curve observations than principal com­ ponents analysis. In fact the complete process from bond data to multiresolution is pre­ sented, including the dedicated Perl programs and the details of the portfolio metrics and specially adapted wavelet construction. The result is more robust statistics which provide balance to the more fragile principal components analysis. TABLE OF CONTENTS CHAPTER PAGE
Thermal Response Modeling System for a Mars Sample Return Vehicle

A multi-dimensional, coupled thermal response modeling system for analysis of hypersonic entry vehicles is presented. The system consists of a high fidelity Navier-Stokes equation solver (GIANTS), a two-dimensional implicit thermal response, pyrolysis and ablation program (TITAN), and a commercial finite element thermal and mechanical analysis code (MARC). The simulations performed by this integrated system include hypersonic flowfield, fluid and solid interaction, ablation, shape change, pyrolysis gas generation and flow, and thermal response of heatshield and structure. The thermal response of the heatshield is simulated using TITAN, and that of the underlying structural is simulated using MARC. The ablating heatshield is treated as an outer boundary condition of the structure, and continuity conditions of temperature and heat flux are imposed at the interface between TITAN and MARC. Aerothermal environments with fluid and solid interaction are predicted by coupling TITAN and GIANTS through surface energy balance equations. With this integrated system, the aerothermal environments for an entry vehicle and the thermal response of the entire vehicle can be obtained simultaneously. Representative computations for a flat-faced arc-jet test model and a proposed Mars sample return capsule are presented and discussed.
On non-perturbative Anderson localization for C^\alpha potentials generated by shifts and skew-shifts

In this paper we address the question of proving Anderson localization (AL) for the operator [H(x,\omega)\psi](n) := - \vp(n+1) - \vp(n-1) + V\bigl(T^n_\omega x\bigr)\psi(n), n\in\mathbb Z where T:\tor^2\to\tor^2 is either the shift or the skew-shift and V is only C^\alpha(\tor^2) for some \alpha>0. We show that under the assumption of positive Lyapunov exponents, (AL) takes place for a.e. frequency, phase, and energy.
Study of multiferroic Bi0.7Dy0.3FeO3 based tunable ring inductor

Bi0.7Dy0. 3FeO3 (BDFO) exhibiting multiferroicity at room temperature is used as a core material for the first time to fabricate a ring-type inductor. More importantly due to the presence magnetoelectric coupling, the BDFO inductor could be tuned magnetically as well as electrically. It is observed that tunability of this inductor is better in the presence of magnetic field than electrical field. This behaviour is correlated to high electrical loss factor (tan δ) of the core material. The dissipation of electrical energy perhaps impedes the strain induced change in permeability. However, there are chances of improvement if tan δ of BDFO is controlled. Nevertheless, simplicity in fabrication and flexibility in operation make tunable BDFO inductors attractive for novel applications. The results give confidence to work on development of miniaturization of BDFO inductor.
Bridging the gap in injustice urbanism

Cities are often divided by invisible borders, and this demarcation is man-made, with some areas featuring large infrastructure, well-maintained parks, gardens, and upscale residential areas. In contrast, other areas are characterized by severe deprivation, inadequate housing, inadequate services, poor recreation and cultural facilities, deterioration, and scarce infrastructure investment. These tangible differences come as symptoms of intangible and persistent divisions in society that distribute unequal opportunities and freedoms among the population. The research problem has shown the lack of clarity and diagnosis of urban problems that led to the emergence of the urban gap in cities). This paper focuses on breaking down the difficult edges created by the urban zoning of the city that would enhance interactions between communities and social classes through a practical study on a selected sample (Al-Hussein neighbourhood and Al-Intisar neighbourhood, Al-Muthanna, Iraq). The research concluded the importance of finding appropriate architectural and urban solutions and strategies to cross the urban inequality gap and achieve justice.
The Role of Protein Arginine Methyltransferases in DNA Damage Response

In response to DNA damage, cells have developed a sophisticated signaling pathway, consisting of DNA damage sensors, transducers, and effectors, to ensure efficient and proper repair of damaged DNA. During this process, posttranslational modifications (PTMs) are central events that modulate the recruitment, dissociation, and activation of DNA repair proteins at damage sites. Emerging evidence reveals that protein arginine methylation is one of the common PTMs and plays critical roles in DNA damage response. Protein arginine methyltransferases (PRMTs) either directly methylate DNA repair proteins or deposit methylation marks on histones to regulate their transcription, RNA splicing, protein stability, interaction with partners, enzymatic activities, and localization. In this review, we summarize the substrates and roles of each PRMTs in DNA damage response and discuss the synergistic anticancer effects of PRMTs and DNA damage pathway inhibitors, providing insight into the significance of arginine methylation in the maintenance of genome integrity and cancer therapies.
Metastasis of Follicular Thyroid Carcinoma to Skull Base: A Case Report

Follicular thyroid carcinoma is a well-differentiated thyroid neoplasm that is classified into widely invasive or minimally invasive carcinoma. Vascular invasion is often characteristic of follicular thyroid carcinoma. There is an estimated 6-20% incidence of distance metastasis with the bone being the most common followed by the lungs and then the lymph nodes. Metastatic spread to the skull base is rare. This case report will cover a patient who presented with follicular thyroid carcinoma and cranial neuropathy and was found to have metastasis to the skull base.
Graded index photonic crystals: A review

A new type of photonic crystal (PC) named graded index (GRIN) PC was proposed by E. Centeno in 2005. It is obtained by appropriately modifying the parameters of a regular PC, thus resulting in gradual index variation. Many applications are inspired by this notion. This review will introduce different ways of designing GRIN PCs from both theoretical and experimental point of views. Some typical applications based on GRIN PCs are presented, followed by the focusing mechanism of GRIN PC.
Unfoldings of quasi-periodic tori

In dit proefschrift worden dynamische systemen (in het bijzonder vectorvelden) beschouwd die invariante tori hebben waarop de bewegingen parallel en, specifieker, quasi-periodiek zijn. (In het quasi-periodieke geval zijn de parallelle bewegingen zodanig dat afzonderlijke banen de tori dicht opvullen.) De systemen hangen af van (externe) parameters en behoren tot de klasse van de algemene (dissipatieve) systemen of tot geschikte deelklassen hiervan. Zie: Samenvatting
Construction of piecewise Lyapunov functions for stabilizing switched systems

This paper discusses the problem of stabilizing a pair of switched linear systems. A control law is developed using a Lyapunov function having a piecewise continuous derivative. A Lyapunov function yielding a stable switching rule is shown to exist as long as there exists a stable convex combination of the system matrices. The use of this stable combination for other control strategies is explored. <<ETX>>
A Magnetic Dynamo Origin for the Submillimeter Excess in Sagittarius A*

The submillimeter bump observed in the spectrum of Sgr A* appears to indicate the existence of a compact emitting component within several Schwarzschild radii, rS, of the nucleus at the Galactic center. This is interesting in view of the predicted circularized flow within ~5-10rS, based on detailed multidimensional hydrodynamic simulations of Bondi-Hoyle accretion onto this unusual object. In this paper, we examine the physics of magnetic field generation by a Keplerian dynamo subject to the conditions pertaining to Sgr A*, and show that the submillimeter bump can be produced by thermal synchrotron emission in this inner region. This spectral feature may therefore be taken as indirect evidence for the existence of this circularization. In addition, the self-Comptonization of the submillimeter bump appears to produce an X-ray flux exceeding that due to bremsstrahlung from this region, which may account for the X-ray counterpart to Sgr A* discovered recently by Chandra. However, the required accretion rate in the Keplerian flow is orders of magnitude smaller than that predicted by the Bondi-Hoyle simulations. We speculate that rapid evaporation, in the form of a wind, may ensue from the heating associated with turbulent mixing of gas elements with large eccentricity as they settle down into a more or less circular (i.e., low-eccentricity) trajectory. The spectrum of Sgr A* longward of ~1-2 mm may be generated outside of the Keplerian flow, where the gas is making a transition from a quasi-spherical infall to a circularized pattern.
The Influence of Biofilm on Selected Properties of Thin-Coat Mineral-Based Plasters on EPS Substrate

This paper discusses changes in the microstructure and water absorption of thin-coat mineral-based plasters after prolonged exposure to the external environment and infected with biological corrosion. The results of laboratory and field tests for external thermal insulation composite system Styrofoam-based plasters are presented. The test samples were taken after 6 years of exposure to the external environment. The microstructure parameters such as porosity distribution and water absorption of the plasters were evaluated. The pore size ranges that were sensitive to frost corrosion and capillary flow were separated in the porosity distribution. Based on the porosity and absorption changes, it was found that biological corrosion interferes with the microstructure of the thin-coat mineral-based plasters on the expanded polystyrene substrate.
Spirometric Evaluation of Effect of Air Pollution on Pulmonary Functions of Traffic Police in Kathmandu Valley

Background and objectives: Traffic police personnel are exposed to ambient air pollution which leads to important health hazards like impairment of lung functions. The objectives of this study were to measure and compare the pulmonary function parameters of traffic police and general duty police and also aimed to evaluate the effect of job duration on those parameters in Kathmandu valley. Materials and methods: A cross-sectional comparative study was done in a total of 133 healthy, non-smoker, male policemen working in Kathmandu valley for a minimum of one year. Out of them, 70 were from traffic police and 63 were from general duty police. MIR Spirolab II was used for pulmonary function test (PFT) measurement. Statistical analysis was done using SPSS version 20. The results were presented as mean ±SD and Independent sample t-test: was used. The p-value <0.05 was considered statistically significant. Pulmonary functions of the two groups were compared. Results: There was a statistically significant decrease in FEV1, FEV1/FVC and FEF25%=75% among policemen working in Kathmandu valley for seven years or more as compared to those working for less than seven years. Although the traffic police had lower FVC, FEV1, FEV1/FVC and PEF in comparison to the general duty police, these differences were not statistically significant. Conclusion: The findings of this study demonstrated that pulmonary functions of both the traffic and the general duty police decrease with increase in duration of job in Kathmandu valley. The pulmonary functions of the traffic police were lower than their predicted values although they were not significantly lower than those of the general duty police. Keywords: Lung function, Spirometry, Traffic policemen, FVC, FEV1, PEF, FEF25%-75%
A generalized variational principle in b-metric spaces

In this paper we establish and prove a generalized variational principle for b-metric spaces. As a consequence, we obtain a weak Zhong-type variational principle in b-metric spaces. We show the applicability of the mentioned generalized variational principle by presenting a Caristi-type fixed point theorem and an extension of the main result for bifunctions - both of them stated in b-metric spaces.
Genetic programming metamodel for rotating beams

This paper investigates the use of Genetic Programming (GP) to create an approximate model for the non-linear relationship between flexural stiffness, length, mass per unit length and rotation speed associated with rotating beams and their natural frequencies. GP, a relatively new form of artificial intelligence, is derived from the Darwinian concept of evolution and genetics and it creates computer programs to solve problems by manipulating their tree structures. GP predicts the size and structural complexity of the empirical model by minimizing the mean square error at the specified points of input-output relationship dataset. This dataset is generated using a finite element model. The validity of the GP-generated model is tested by comparing the natural frequencies at training and at additional input data points. It is found that by using a non-dimensional stiffness, it is possible to get simple and accurate function approximation for the natural frequency. This function approximation model is then used to study the relationships between natural frequency and various influencing parameters for uniform and tapered beams. The relations obtained with GP model agree well with FEM results and can be used for preliminary design and structural optimization studies.
Extraordinarily Rare Isolated Intraperitoneal Urinary Bladder Rupture in Blunt Abdominal Injury Without Pelvic Fracture: An Aide-Mémoire

Isolated urinary bladder rupture caused by blunt abdominal trauma is an infrequent injury, with less than 2% of all cases. It is most often found in traffic accidents and is usually associated with pelvic fractures. While an extraperitoneal bladder injury is mostly treated conservatively, an intraperitoneal one is mostly treated surgically. We present a 54-year-old obese man injured in a traffic accident, with an intraperitoneal rupture of the bladder after blunt abdominal trauma with no signs of pelvic fracture and without signs of traumatic injury to the abdominal organs. The vignette case constitutes a bladder injury that was treated surgically and sutured in two layers with absorbable thread, with the placement of a urinary catheter. The patient recovered without complications and was discharged from the ward on the seventh postoperative day. Of note, the clinical presentation of a bladder rupture can be manifested as a nonspecific lower abdominal pain or with symptoms of an acute abdomen and that is why imaging plays a major role in the diagnosis and further treatment procedures. Surgical treatment of such injuries can be performed laparoscopically or as open surgery. To this end, rapid diagnosis of bladder rupture is necessary because it can lead to complications that endanger patients if overlooked.
