The Effect of Snail Mucus (Achatina Fulica) Toward The Activity and Chronicity Indices of Renal Histology in Pristane-Induced Lupus Nephritis Mice Model

Background: Snail mucus (Achatina Fulica) has been known to contain heparan sulfate, and acharan sulfate, a glycosaminoglycan with anti-inflammatory properties and might repair the injured glomeruli. Aim: This study aims to find the effect of snail mucus on activity and chronicity indices of renal histology in a pristane-induced lupus nephritis mice model. Method: This was an experimental study with a post-test-only control group design using 42 mice strains Balb/C. Mice were randomized into six groups: control, lupus nephritis, methylprednisolone, snail mucus 0.5 ccs, snail mucus 0,5 cc and methylprednisolone, and snail mucus one cc and methylprednisolone group. Result: Snail mucus significantly affected the activity index (p = 0.001). The lowest activity index was shown by snail mucus one cc and methylprednisolone group. While the chronicity index was not significantly affected by the snail mucus with p = 0.195. Snail mucus decreases the activity index of renal histology in the pristane-induced lupus nephritis mice model but not the chronicity index.

Galvanometer-Based Scanners: Mathematical Model and Alternative Control Structures for Improved Dynamics and Immunity to Disturbances

Galvanometer scanners (GSs) are the most utilized optomechatronic systems for laser scanning. A GS consists of an oscillatory element (which includes the galvomirror) in a motor structure equipped with a positioning servo-system built usually in a closed-loop structure and controlled by different algorithms. Such structures have to provide speed and accuracy in the positioning of the laser beam or for raster scanning. Although tackled by numerous studies, on different aspects, this is still an open problem. The aim of this study is to approach it in a simple way and to provide a low cost solution to increasing accuracy by developing a structure which is more immune to disturbances than the classical one. In order to do this, a basic closed-loop GS which consists of a proportional-derivative (PD-L1) controller and a servo-motor is considered first. The mathematical model and the GS parameters are identified using a theoretical approach followed by experimental identifications. The extended control solution is developed starting from this basic GS structure by introducing a proportional-integrative (PI) controller in series with the PD-L1 controller of the GS; further on, a P-L1 reference filter is added to this new structure. In the absence of disturbances, both the basic and the extended control solutions show good tracking performances, but the basic solution is faster. In the presence of constant disturbances which can affect the servo-system, the latter structure (extended and filtered) has the best dynamical and tracking performances.
Rainforest conversion to plantations fundamentally alters energy fluxes and functions in canopy arthropod food webs

Tropical rainforests around the world are rapidly converted into cash crop agricultural systems. The associated massive losses of plant and animal species lead to changes in arthropod food webs and the energy ﬂuxes therein. These changes are poorly understood, in particular in the extremely biodiverse canopies of tropical ecosystems. Using canopy fogging followed by stable isotope and energy ﬂux analyses, we show that land-use conversion from rainforest to rubber and oil palm plantations not only causes a drastic reduction in energy ﬂuxes of up to 75%, but also shifts ﬂuxes among trophic groups. While rainforest featured high levels of both herbivory and algae-microbivory, and a balanced ratio of herbivory to predation, relative ﬂuxes were shifted towards predation in rubber and towards herbivory in oil palm plantations, indicating profound shifts in ecosystem functioning. Our results highlight that the ongoing loss of animal biodiversity and biomass in tropical canopies degrades animal-driven functions and restructures canopy food webs.
William Richard Dickinson (1931-2015) A Personal Farewell

Introduction With the passing of Bill Dickinson in mid-July, the geologic community of New Mexico, and everywhere else, lost an enduring colleague and friend. By a remarkable combination of intellect, self-confidence, engaging humility, and prodigious output of published work, he influenced and challenged (to date) three generations of geoscientists and other researchers—sedimentary geologists, igneous petrologists, tectonicists, sandstone petrologists, archeologists and university students, to list a few categories—around the globe. Bill looms large on the geologic landscape of western North America and surely the Big Book on Cordilleran Tectonics contains a longish chapter entitled “The Life and Times of Bill Dickinson. ” To summarize that chapter in a few pages might be considered foolish; if so, consider the following a momentary lapse of reason.

Restoration of Static JPEG Images and RGB Video Frames by Means of Nonlinear Filtering in Conditions of Gaussian and Non‐Gaussian Noise

The use of nonlinear Markov process filtering makes it possible to restore both video stream frames and static photos at the stage of preprocessing. The present paper reflects the results of research in comparison of these types image filtering quality by means of special algorithm when Gaussian or non‐Gaussian noises acting. Examples of filter operation at different values of signal‐to‐noise ratio are presented. A comparative analysis has been performed, and the best filtered kind of noise has been defined. It has been shown the quality of developed algorithm is much better than quality of adaptive one for RGB signal filtering at the same a priori information about the signal. Also, an advantage over median filter takes a place when both fluctuation and pulse noise filtering.
CPAD: Component Pixel-Aware Multispectral Image Destriping

Stripe noise removal of multispectral images (MSIs) is a challenging topic and has attracted substantial research attention in remote sensing areas. Existing destriping methods mainly concentrate on patch-based model representation, which ignores the heterogeneous components across the degraded MSIs and poorly utilizes the prior knowledge of the image cubes of the MSIs on high-level perception. In this article, we present a component pixel-aware MSIs destriping method. Intuitively, the image cube of the MSIs is divided into three different components (the jump, transition, and gentle components) based on the gradients of each pixel. Then, three different regularization operators are adopted adaptively for different components in a pixel-level manner. In addition, to properly depict the stripe cube of the MSIs, we exploit the nonconvex nonsmooth iteratively reweight nuclear norm. By incorporating both improved terms, our proposed method can estimate the component-variant linear representation coefficients and model the structural information of both the stripe cube and image cube. The alternating direction method of multipliers (ADMM) is adopted to solve the proposed method. Evaluating various destriping performance measurements, the algorithm proposed in this article outperforms other state-of-the-art methods under extensive experiments on synthetic and real datasets.
A New Orbit for the Eclipsing Binary V577 Oph

Pulsating stars in eclipsing binary systems are unique objects for providing constraints on stellar models. To fully leverage the information available from the binary system, full orbital radial velocity curves must be obtained. We report 23 radial velocities for components of the eclipsing binary V577 Oph, whose primary star is a δ Sct variable. The velocities cover a nearly complete orbit and a time base of 20 years. We computed orbital elements for the binary and compared them to the ephemeris computed by Creevey et al. The comparison shows marginally different results. In particular, a change in the systemic velocity by −2 km s−1 is suggested by our results. We compare this systemic velocity difference to that expected due to reflex motion of the binary in response to the third body in the system. The systemic velocity difference is consistent with reflex motion, given our mass determination for the eclipsing binary and the orbital parameters determined by Volkov & Volkova for the three-body orbit. We see no evidence for the third body in our spectra, but we do see strong interstellar Na D lines that are consistent in strength with the direction and expected distance of V577 Oph.
On the Representation Theory of Semisimple Lie Groups

This thesis is an expository account of three central theorems in the representation theory of semisimple Lie groups, namely the theorems of Borel–Weil–Bott, Casselman– Osborne and Kostant. The first of these realizes all the irreducible holomorphic representations of a complex semisimple Lie group G in the cohomology of certain sheaves of equivariant line bundles over the flag variety of G. The latter two theorems describe the Lie algebra cohomology of a maximal nilpotent subalgebra of g with coefficients in an irreducible g-module. Applications to geometry and representation theory are given. Also included is a brief overview of Schmid’s far-reaching generalization of the Borel– Weil–Bott theorem to the setting of unitary representations of real semisimple Lie groups on (possibly infinite-dimensional) Hilbert spaces.
MATCHING DOMINATION IN GRAPHS

A dominating set D is called a connected dominating set, if it induces a connected subgraph in G. Since a dominating set must contain atleast one vertex from every component of G, it follows that a connected dominating set for a graph G exists if and only if G is connected. The minimum of cardinalities of the connected dominating sets of G is called the connected domination number of G and is denoted by (G). We have defined new parameter called the matching dominating set and the matching domination number. We prove the following: • If G is a graph without isolated vertices, then γ ≤ . • There exist bipartite graphs for which ≠ . • There exist graphs which are not bipartite for which = • ( ) = 2 • ( , ) = 2 • For any positive integer n, , = 1, , = 2. •For any positive integer n, ( ) = 1, ( ) = 2, where is a wheel on n vertices. • For any positive integer n, ( ) = , ( ) = 2
THE BRAUER-MANIN OBSTRUCTION ON FAMILIES OF HYPERELLIPTIC CURVES

OF THE DISSERTATION The Brauer-Manin Obstruction on Families of Hyperelliptic Curves by Thom Tyrrell Dissertation Director: Jerrold Tunnell In [19], Manin introduced a way to explain the failure of the Hasse principle for algebraic varieties over a number field. For curves, the problem of whether all such failures can be explained by this method is open. In this thesis, we construct unramified quaternion algebras that obstruct the existence of rational points on families of curves admitting maps to elliptic curves. In Chapter 1, we introduce the Brauer group of a projective variety. For curves, we relate the Brauer group to torsors over the Jacobian of the curve, and establish some properties of the Brauer group over local fields that will simplify later computations. In Chapter 2, we define the Brauer-Manin obstruction and show that it explains all failures of the Hasse principle for genus 1 curves and curves without a degree 1 rational divisor. After reviewing a topological and more computational characterization of the obstruction, we note that it suffices to consider curves that admit maps to positive rank abelian varieties. Having established the obstruction, we introduce the motivating example for this thesis a construction by D.Quan [21] of a genus 11 hyperelliptic curve and an unramified quaternion algebra that obstructs the existence of rational points on it.
Flow-induced vibration of D-section cylinders: an afterbody is not essential for vortex-induced vibration

While it has been known that an afterbody (i.e. the structural part of a bluff body downstream of the flow separation points) plays an important role affecting the wake characteristics and even may change the nature of the flow-induced vibration (FIV) of a structure, the question of whether an afterbody is essential for the occurrence of one particular common form of FIV, namely vortex-induced vibration (VIV), still remains. This has motivated the present study to experimentally investigate the FIV of an elastically mounted forward- or backward-facing D-section (closed semicircular) cylinder over the reduced velocity range $2.3\leqslant U^{\ast }\leqslant 20$ , where $U^{\ast }=U/(f_{nw}D)$ . Here, $U$ is the free-stream velocity, $D$ the cylinder diameter and $f_{nw}$ the natural frequency of the system in quiescent fluid (water). The normal orientation with the body’s flat surface facing upstream is known to be subject to another common form of FIV, galloping, while the reverse D-section with the body’s curved surface facing upstream, due to the lack of an afterbody, has previously been reported to be immune to VIV. The fluid–structure system was modelled on a low-friction air-bearing system in conjunction with a recirculating water channel facility to achieve a low mass ratio (defined as the ratio of the total oscillating mass to that of the displaced fluid mass). Interestingly, through a careful overall examination of the dynamic responses, including the vibration amplitude and frequency, fluid forces and phases, our new findings showed that the D-section exhibits a VIV-dominated response for $U^{\ast }<10$ , galloping-dominated response for $U^{\ast }>12.5$ , and a transition regime with a VIV–galloping interaction in between. Also observed for the first time were interesting wake modes associated with these response regimes. However, in contrast to previous studies at high Reynolds number (defined by $Re=UD/\unicode[STIX]{x1D708}$ , with $\unicode[STIX]{x1D708}$ the kinematic viscosity), which have showed that the D-section was subject to ‘hard’ galloping that required a substantial initial amplitude to trigger, it was observed in the present study that the D-section can gallop softly from rest. Surprisingly, on the other hand, it was found that the reverse D-section exhibits pure VIV features. Remarkable similarities were observed in a direct comparison with a circular cylinder of the same mass ratio, in terms of the onset $U^{\ast }$ of significant vibration, the peak amplitude (only approximately 6 % less than that of the circular cylinder), and also the fluid forces and phases. Of most significance, this study shows that an afterbody is not essential for VIV at low mass and damping ratios.
Adopted Coping Strategies among Professionals in Stress Management- A Questionnaire Based Survey

Background: Stress may affects professionals’ health and their professional performance. In present era of globalization where competition, novelty and change is a contributing factor in stress development and stimuli for tension, anxiety anger and behavioral changes ultimately lead to health problems. Coping strategies are then adopted to manage these stresses. Aim: To uncover the level of stress, the major responses in regards to the imposed stress and ultimately to inquire the adopted strategies to cope with stressful situation in professionalism. Methods: Thismulticenter crossestional survey was conducted among 257 participants of different level professions of different institute and departments of Grand Asian University (formerly Islam medical & dental college) from June – August 2021 and at Jinnah Sindh medical University (JSMU) from Feb – April 2022. Stress causes and major responses were accessed by well-structured preexisting validated questionnaires (consent taken by mail). Sociodemograpic variables were taken using self-generated questionnaire comprising question about age, sex, education level, financial status, job level and marital status. Aim: To access the adopted coping strategies by the professional in stress management in their professional tasks Results:Major respondents of study (58.2%) were female followed by male (41.8%) , 82% with age group 20 -35 years old, 38.7% were married, 47.7% from joint family system, 52.3% were graduated, 83.2% with less than 100,000 PKR income per month. The major cause of stress was No recreational activity (32%), Frequent travelling (36.3%), Working on holidays (14.5%), Complications from children (22.7%) and for disorganization or misfiring of system (23.8%). Major responses to stress including unable to recall things (34.4%), Unable to express their feeling with their social circle (30.1%), unable to focus on their job related tasks (24.2%). abdominal pain (23.8%), usually feel stressed (23.8%) and get disappointed (19.5%). Practical implication: Although the findings of coping strategies in this study is emotional based coping which is considered the weak one and these findings reveals that stress among professionals is not much addressed which potentially placed hindrances in outcomes thus the organizational policy makers are suggested to make these consideration for better outcome and potential benefits of the professionals and organization to excel outcome and reduce health hazards. Conclusion: This research revealed that professionals were actively involved in emotional focused coping strategies and typically indicates adoptive coping mechanisms. Keywords: Stress, coping, strategies, job level, social support, health problems

A unified framework for corotational flexible multibody system dynamics formulations.

Corotational formulations play an important role for flexible multibody dynamics systems, because they reflect the nature of many technical systems undergoing arbitrarily large rigid body motions but small deformations within each body. This paper defines flexible multibody dynamics and corotational formulations in this context. Furthermore, the «ingredients» and workflow of a flexible multibody dynamics simulation are briefly addressed for the reader less familiar with the topic. This part also points to major review papers and textbooks in the field, and embeds the unified formulations in the literature. The paper's main part presents state-of-the-art corotational flexible multibody dynamics formulations in a systematic and unified way. In this formulation part, the standard integral-based floating frame of reference formulation with modal reduction and with the conventionally employed lumped mass approximation is presented, and its drawbacks highlighted. Then, the so-called nodal-based, i.e., space-wise discretized, equations of motion are presented for several up-to-date nodal-displacement-based formulations within a unified framework. This approach clearly shows the equivalence of the presented formulations, and highlights the fact that the formulations differ only in the choice of degrees of freedom. Moreover, this contribution also intends to reduce the information and complexity within the scientific literature, since this unified framework allows the derivation of these formulations with significantly less effort.

Revealing the intrinsic anisotropy of superconducting Sr$_x$Bi$_2$Se$_3$

We reveal that unusual 2-fold in-plane symmetry of superconductivity, recently explored in Sr- doped topological insulator Bi$_2$Se$_3$, and associated with nematic topological superconductivity, is accompanied by co-aligned features in magnetoresistance well above critical temperature, signifying structural anisotropy of the crystal. Our detailed X-ray diffraction studies of the superconducting crystals do reveal small structural distortions (about 0.02 % elongation in one in-plane crystallographic direction). Additionally, we reveal that the crystal consists of crystallites with high anisotropy in orientation of the crystallite axes. These observations indicate in favor of structural scenario for the apparent nematic superconductivity in this material.
