description: Background: TB detection rate remains critical stumbling block for TB control. Though conventional methods for TB detection exist; GeneXpert MTB/RIF assay represents a paradigm shift in the diagnosis of TB and MDR-TB by simultaneous detection of M.tuberculosis and rifampicin resistance bacilli. However information regarding the performance characteristics of Xpert MTB/RIF assay is scarce in Ethiopia. Objective: To evaluate the performance of Xpert MTB/RIF assay for diagnosis of pulmonary tuberculosis and detection of Rifampicin resistance in sputum specimens at Karamara hospital, Jigjiga. Materials and methods: A total of 227 paired expectorated sputum samples from patients with signs and symptoms of suggestive of tuberculosis at Karamara hospital during February 2014 to May 2014 were recruited by consecutive sampling method. Sputum sample was tested directly by Ziehl-Neelsen staining and Xpert MTB/RIF assay without NALC-NaOH decontamination and sputum samples were cultured for isolation and drug sensitivity testing of TB bacilli. Diagnostic performance of Xpert MTB/RIF assay and AFB smear microscopy was calculated using sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios against culture as the gold standard. Results with contaminated cultures (for both LJ and MGIT) and failed Xpert MTB/RIF were excluded from analysis. Results: Overall 25.5% (58/227) samples were positive for MTBC by MGIT and/or LJ media of which 36.2 % (21/58) and 65.5% (35/58) were positive by AFB smear microscopy and Xpert MTB/RIF respectively. The sensitivity, specificity, positive and negative predictive value of Xpert MTB/RIF assay were 65.5% (95% CI: 53.3-77.7%), 96.3% (95% CI: 93.4-99.2%), 86.4% (95% CI: 76.2-96.5%), and 88.6% (95% CI: 83.9-93.3%) respectively. Eighteen (31.0%, 18/58) more cases, which were smear microscopy negative, were detected by Xpert MTB/RIF assay Conclusion: Xpert MTB/RIF assay demonstrated high sensitivity in detecting MTBC in sputum specimens compared with conventional AFB smear microscopy. However, it demonstrated suboptimal sensitivity in smear negative patients compared to culture test. Keywords: Xpert MTB/RIF assay, NPV, PPV, Sensitivity, Specificity

description: We study perturbative unitarity in a Lorentz-symmetry-violating QED model with higher-order derivative operators in the light of the results of Lee and Wick to preserve unitarity in indefinite metric theories. Specifically, we consider the fermionic sector of the Myers-Pospelov model, which includes dimension-five operators, coupled to standard photons. We canonically quantize the model, paying attention to its effective character, and show that its Hamiltonian is stable, emphasizing the exact stage at which the indefinite metric appears and decomposes into a positive-metric sector and a negative-metric sector. Finally, we verify the optical theorem at the one-loop level in the annihilation channel of the forward-scattering process $e^+(p_2, r) + e^-(p_1,s)$ by applying the Lee-Wick prescription in which the states associated with the negative metric are left out from the asymptotic Hilbert space, but nevertheless are considered in the loop integration via the propagator.

description: We compute the resummed on-shell $W^+ W^-$ production cross section under a jet-veto at the LHC to partial N$^3$LL order matched to the fixed order NNLO result. Differential NNLO cross sections are obtained from an implementation of $q_T$ subtraction in Sherpa. The two-loop virtual corrections to the $q \bar q \rightarrow W^+ W^-$ amplitude, used in both fixed order and resummation predictions, are extracted from the public code {\tt qqvvamp}. We perform resummation using soft collinear effective theory (SCET), with approximate beam functions where only the logarithmic terms are included at two-loop. In addition to scale uncertainties from the hard matching scale and the factorization scale, rapidity scale variations are obtained within the analytic regulator approach. Our resummation results show a decrease in the jet-veto cross-section compared to NNLO fixed order predictions, with reduced scale uncertainties compared to NNLL+NLO resummed predictions. We include the loop-induced $gg$ contribution with jet veto resummation to NLL+LO. The prediction shows good agreement with recent LHC measurements.

description: The non-linear response of a beam splitter to the coincident arrival of interacting particles enables numerous applications in quantum engineering and metrology yet poses considerable challenge to achieve focused interactions on the individual particle level. Here we probe the coincidence correlations at a mesoscopic constriction between individual ballistic electrons in a system with unscreened Coulomb interactions and introduce concepts to quantify the associated parametric non-linearity. The full counting statistics of joint detection allows us to explore the interaction-mediated energy exchange. We observe an increase from 50\% up to 70\% in coincidence counts between statistically indistinguishable on demand sources, and a correlation signature consistent with independent tomography of the electron emission. Analytical modeling and numerical simulations underpin consistency of the experimental results with Coulomb interactions between two electrons counterpropagating in a dispersive quadratic saddle, and demonstrate interactions sufficiently strong, $U/(\hbar ω) > 10$, to enable single-shot in-flight detection and quantum logic gates.

description: The ruby lattice is a four-valent lattice interpolating between honeycomb and triangular lattices. In this work we investigate the topological spin-liquid phases of a spin Hamiltonian with Kitaev interactions on the ruby lattice using exact diagonalization and perturbative methods. The latter interactions combined with the structure of the lattice yield a model with $\mathbb{Z}_2 \times \mathbb{Z}_2$ gauge symmetry. We mapped out the phase digram of the model and found gapped and gapless spin-liquid phases. While the low energy sector of the gapped phase corresponds to the well-known topological color code model on a honeycomb lattice, the low-energy sector of the gapless phases is described by an effective spin model with three-body interactions on a triangular lattice. A gap is opened in the spectrum in a small magnetic field. We argue that the latter phases could be possibly described by exotic excitations, whose their spectrum is richer than the Ising phase of the Kitaev model.

description: A holographic field theory on a fixed black hole background has a gravitational dual represented by a black funnel or a black droplet. These states are "detuned" when the temperature of the field theory near the horizon does not match the temperature of the background black hole. In particular, the gravitational dual to the Boulware state must be a detuned solution. We construct detuned droplets and funnels dual to a Schwarzschild background and show that the Boulware phase is represented by a droplet. We also construct hairy black droplets associated to a low-temperature scalar condensation instability and show that they are thermodynamically preferred to their hairless counterparts.

description: Through a systematic symmetry and topology analysis we establish that three-dimensional chiral superconductors with strong spin-orbit coupling and odd-parity pairing generically host low-energy nodal quasiparticles that are spin-non-degenerate and realize Majorana fermions in three dimensions. By examining all types of chiral Cooper pairs with total angular momentum $J$ formed by Bloch electrons with angular momentum $j$ in crystals, we obtain a comprehensive classification of gapless Majorana quasiparticles in terms of energy-momentum relation and location on the Fermi surface. We show that the existence of bulk Majorana fermions in the vicinity of spin-selective point nodes is rooted in the non-unitary nature of chiral pairing in spin-orbit-coupled superconductors. We address experimental signatures of Majorana fermions, and find that the nuclear magnetic resonance (NMR) spin relaxation rate is significantly suppressed for nuclear spins polarized along the nodal direction as a consequence of the spin-selective Majorana nature of nodal quasiparticles. Furthermore, Majorana nodes in the bulk have nontrivial topology and imply the presence of Majorana bound states on the surface that form arcs in momentum space. We conclude by proposing the heavy fermion superconductor PrOs$_4$Sb$_{12}$ and related materials as promising candidates for non-unitary chiral superconductors hosting three-dimensional Majorana fermions.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: In Ethiopia, the need for enhanced access to insurance at affordable rates to the lower end of the market is well set out in the National Growth and Transformation Plan II, 2015/16-2020/21. Access to insurance services is important for low-income groups as they are more vulnerable to unexpected losses due to natural disasters. Consequently, reaching out to this group and mitigate the level of risk as it will drive them to deeper level of poverty. To bridge this need, only five insurance firms have developed products that targeted this section of the market. However, several challenges affect the success of rolling out the products into the insurance to the market. This research sought to establish factors affecting the provision of microinsurance in Ethiopia by focusing on socio-institutional factors as independent variables namely client awareness, trust, government regulation and technology. The research adopted a descriptive research design whereby data was collected using a structured questionnaire that was distributed to 130 respondents (supervisors and managers) in the Ethiopian Insurance Companies. The respondents were selected using purposive sampling technique. The data analysis employed was descriptive and inferential statistics. Pearson Correlation and Multiple regression analysis were used to examine the relationship between independent variables and provision of microinsurance using SPSS20.0 .The result revealed that all independent variables, client awareness, technology, trust and government regulation showed significant association. Because of the limited knowledge on the insurance products, there is a need for a rigorous and wellcoordinated approach on insurance to be offered to the target market and this will rope in the support of donors, the federal and regional governments .The factors under analysis show attention to be given to demand and supply sides of microinsurance, individual mindsets and structural factors that might require systemic intervention by the firms, government and clients.

description: In this paper, we show a no-go theorem for static spherically symmetric black holes with vector hair in Einstein-$Λ$-Vector-Tensor-Gauss-Bonnet theory where a complex vector field non-minimally couples with Gauss-Bonnet invariant. For this purpose, we expand metric functions and radial functions of a vector field around the event horizon, and substitute the expansions into equations of motion. Demanding that the equations of motion are satisfied in each order, we show that the complex vector field vanishes on the event horizon. Moreover, when the event horizon is degenerated, it is also implied that the complex vector field vanishes on and outside the horizon.

Creators: name: Adare, Adugna
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Advertising is a prominent feature of modern business operations. One could encounter advertising messages, while watching TV, reading magazines, listening to the radio, using the internet or even simply walking down the street, as advertising has a stimulating influence on purchasing behavior of the consumers. Advertising provides a platform for companies to create awareness about their products or services and how consumers could make the best choice out of such products. This study evaluated the impact of advertising expenses on the sales volume of MOHA Soft Drinks Industries S.C. This study was based on secondary data collected for advertising expenditures and sales volume of the company over the period of 2000 to 2015 from its annual financial and sales reports. Among the objectives of the study is to determine the extent to which advertising costs impact on the sales volume of the company under study. It also seeks to study the nature of advertising as well as the relationship between advertising and sales. Explorative research design was adopted for the study to get deep insight of the impact that advertising cost has on sales volume of the company. Statistical regression analysis using Ordinary Least Squares (OLS) and correlation analysis have been performed to test the hypothesis of the study. The test result showed that advertising expenses has a positive significant impact on sales volume of the companies; and also a test showed a positive significant relationship between advertising and sales volume of the company. Other variables which are not included in the model are explained by the error term in the model. The study concluded that that there is a significant improvement in the sales of the company as a result of advertising. It was recommended that organizations should educate the general public through advertising on the uses, functions and benefits of their products. The company should exhaustively advertise any change in the company which can increase sales volume. For instance, if there is a price discount or new product development or a prize coupon, it should be advertised. Key words: Sales Volume, Advertising expense,

On Vibration Transmission Reciprocity In Modulated Materials
Creators: Wu, Jiuda

Publisher: name: University of Alberta Library
Year: 2022

Modulated materials are artificially structured materials with effective properties that vary periodically in time in response to an external stimulus. The time-dependent elastic properties of a modulated material enable them to exhibit vibration transmission characteristics that are not typical of regular materials. Modulated materials have a demonstrated ability to restrict the transmission of waves to only one direction. Thus, the transmission properties become dependent on the direction of the propagating waves, in contrast with the reciprocity principle in linear time-invariant materials. In this work, we study the reciprocity of vibration transmission in a discrete model of a modulated material with two degrees of freedom. We highlight the role of the difference in modulation phases of the two units on controlling the reciprocity bias in the linear operating regime. We then investigate and discuss the influence of nonlinear elasticity on the transmission reciprocity, highlighting the significant role played by the type of nonlinearity. This work facilitates further parametric studies on the combined effects of modulation and nonlinearity on reciprocity in modulated materials.

description: We study supersymmetry enhancement from ${\cal N}=3$ to ${\cal N}=4$ proposed by Aharony and Tachikawa by using string junctions in S-folds. The central charges carried by junctions play a central role in our analysis. We consider planer junctions in a specific plane. Before the S-folding they carry two complex central charges, which we denote by $Z$ and $\bar Z$. The S-fold projection eliminates $\bar Z$ as well as one of the four supercharges, and when the supersymmetry is enhanced $\bar Z$ should be reproduced by some non-perturbative mechanism. For the models of $\mathbb{Z}_3$ and $\mathbb{Z}_4$ S-folds which are expected to give $SU(3)$ and $SO(5)$ ${\cal N}=4$ theories we compare the junction spectra with those in perturbative brane realization of the same theories. We establish one-to-one correspondence so that $Z$ coincides. By using the correspondence we also give an expression for the enhanced central charge $\bar Z$.

Year: 2017

description: The purpose of this study was to investigate the effect of customer relationship management on customer loyalty: the case of current account customers of three commercial banks in Ethiopia. A theoretical framework was used as a guideline to test the relationships between relationship marketing dimensions (trust, commitment, empathy, and conflict handling) and customer loyalty. In order to obtain information from customers of the banks quantitative data collection tools were used. Non-probability sampling method was employed to select respondents; specifically convenience sampling technique was used. Accordingly, the study has selected 384 respondents from Commercial Bank of Ethiopia, Awash International Bank S.C., and Deshen Bank S.C. branches that operates in Addis Ababa and 384 questionnaires were distributed to customers, all were collected. Descriptive statistics were used to analyze demographic data and correlation, regression and independent sample t-test were used to analyze the five scaled questions.To aid computation statistical package for social science (SPSS) soft ware version 20.0 was used. The findings show that relationship marketing dimensions have effect on customer loyalty. All the independent variables are positively and directly related to customer loyalty in banking industry. The relationship between relationship marketing and customer loyalty is significant. Therefore, to retain and develop loyal customers, the banks should be trustworthy and show commitment, providing individualized attention to customers and must resolve conflicts in a manner that will eliminate unimportant loss and inconvenience to their customers

Ihre Attraktivität speist sich vor allem aus dem Versprechen, dass durch eine gezielte mentale Beeinflussung konkret überprüfbarer, rascher Nutzen für den Betrieb erzielt werde. Interessant ist diese Entwicklung unter zwei Gesichtspunkten: Zum einen spiegelt sich darin der derzeit vorherrschende Trend zur Ökonomisierung des Weiterbildungsgeschehens wider. Zum anderen liegt darin ein besonders heikler Aspekt der modernen Entdeckung des "Produktionsfaktors Mensch". Es geht darum, möglichst viele Beschäftigte (nicht nur als Arbeitskraft, sondern) als ganze Menschen so für das Unternehmen zu aktivieren, dass sie weitgehend selbstverantwortlich und selbstkontrolliert mit den steigenden Anforderungen an ihre Leistungsbereitschaft umzugehen verstehen.

description: Simulating quantum nonlocality and steering requires augmenting pre-shared randomness with non-vanishing communication cost. This prompts the question of how one may provide such an operational characterization for the quantumness of correlations due even to unentangled states. Here we show that for a certain class of states, such quantumness can be pointed out by superlocality, the requirement for a larger dimension of the pre-shared randomness to simulate the correlations than that of the quantum state that generates them. This provides an approach to define the nonclassicality of local multipartite correlations in convex operational theories.

description: This research aims to study the influence of after-sales service quality on the overall customer satisfaction in case of Lifan Motors. The research measured the service quality of Lifan Motors' after sales service station using the SERVQUAL model and additional after sales services activities. The five SERVQUAL dimensions developed by Parasuraman et al (1988) were used to assess the customer satisfaction. But the measurement was done using SERVPERF scale. Quantitative research method and nonprobability sampling technique (convenience) was applied. Data were collected through a survey of 362 after sales service customers. Respondents were asked to evaluate several items related to their after-sales service experience at Lifan Motors. Data were analyzed using correlation and linear regression model. The results of the study revealed that the majorities of Lifan Motors after sales service station customers are dissatisfied with the overall maintenance and repair as well as spare parts supply services delivery while a greater number of customers are satisfied with the overall warranty service of the services station. The findings showed that there is a relationship between SERVPERF dimensions (assurance, empathy and tangibility)and Customer Satisfaction, there is a significant positive correlation, and also, there is negative correlation between the other SERVPERF dimensions (reliability and responsiveness). The study recommends the company should work in improving its overall maintenance and repair as well as spare parts supply services provision. The company can also accumulate customer's loyalty by largely focusing on the development of assurance, empathy and tangibility SERVPERF dimensions

description: We develop the self-learning Monte Carlo (SLMC) method, a general-purpose numerical method recently introduced to simulate many-body systems, for studying interacting fermion systems. Our method uses a highly-efficient update algorithm, which we design and dub "cumulative update", to generate new candidate configurations in the Markov chain based on a self-learned bosonic effective model. From general analysis and numerical study of the double exchange model as an example, we find the SLMC with cumulative update drastically reduces the computational cost of the simulation, while remaining statistically exact. Remarkably, its computational complexity is far less than the conventional algorithm with local updates.

description: Strong adhesives rely on reduced stress concentrations, often obtained via specific geometry or composition of materials. In many examples in nature and engineering prototypes, the adhesive performance relies on structural rigidity being placed in specific locations. A few design principles have been formulated, based on parametric optimization, while a general design tool is still missing. We propose to use topology optimization to achieve optimal stiffness distribution in a multi-material adhesive backing layer, reducing stress concentration at specified locations. The method involves the minimization of a linear combination of J-integral and strain energy. While the J-integral minimization is aimed at reducing stress concentration, we observe that the combination of these two objectives ultimately provides the best results. We analyze three cases in plane strain conditions, namely (i) double-edged crack and (ii) center crack in tension and (iii) edge crack under shear. Each case evidences a different optimal topology with (i) and (ii) providing similar results. The optimal topology allocates stiffness in regions that are far away from the crack tip, intuitively, but the allocation of softer materials over stiffer ones can be non-trivial. To test our solutions, we plot the contact stress distribution across the interface. In all observed cases, we eliminate the stress singularity at the crack tip. Stress concentrations might arise in locations far away from the crack tip, but the final results are independent of crack size. Our method ultimately provides optimal, flaw tolerant, adhesives where the crack location is known.

Undermining the Ideological Construction of “Rhetoric Poetry” - A Structural-Formative Approach  Abstract: My first goal in the current study is to absorb the idea of poetry column and rhetoric in Arabic poetry, as being two complementary trends, one of them is created to undermine the other. However, the basic hypothesis in this study is that the Arab rhetorical poetry and the idea of poetry column are moving towards two different frames: the first is related to political, social, and cultural concerns, and the second is related to linguistic and literary concerns. In addition, it seeks to prove that rhetorical poetry and the idea of poetry column are products of two social groups that express their vision for the world through their literary works, emphasizing on their aspirations to power and life in this work and hoping to change the existing situation while solving the political and social issues that should have been differently tackled elsewhere.

description: We describe the phenomenon of localization in the epidemic SIS model on highly heterogeneous networks in which strongly connected nodes (hubs) play the role of centers of localization. We find that in this model the localized states below the epidemic threshold are metastable. The longevity and scale of the metastable outbreaks do not show a sharp localization transition, instead there is a smooth crossover from localized to delocalized states as we approach the epidemic threshold from below. Analyzing these long-lasting local outbreaks for a random regular graph with a hub, we show how this localization can be detected from the shape of the distribution of the number of infective nodes.

In this paper, an interface crack between piezoelectric and orthotropic half-spaces has been studied in detail. By using integral transformation techniques, the present mixed boundary value problem was reduced to the solution of singular integral equations, which can be further reduced to solving a Riemann-Hilbert problem with a closed form solution. The crack-tip singularities of the interface crack have been investigated for possible combinations of the piezoelectric and orthotropic materials; a criterion based on the g-parameter of the Riemann-Hilbert problem is introduced to study the possible singularity behavior of the interface crack.  It is shown that there can be either oscillatory or non- oscillatory singularity for the interface crack depending on the  particular combinations of the bi-materials. A closed form solution for stresses, electric field and electric displacement in the cracked bi-materials is given, and of particular interests, the analytical expression of the stresses and electric displacements along the interface has been obtained.

description: Auf Basis einer Befragung von 534 Erwerbstätigen aus 14 nordostdeutschen ländlichen Orten wird die Verteilung von Gratifikationskrisen über Alter, Geschlecht und Beschäftigungssektor sowie die Bedeutung der Belastung durch berufliche Gratifikationskrisen für die Gesundheit und Zufriedenheit untersucht. Erwartungsgemäß wurden starke alters- und geschlechtskontrollierte Zusammenhänge zwischen Gratifikationskrisen und diversen Maßen für Gesundheit und Zufriedenheit ermittelt. Der Vergleich mit einer bundesrepräsentativen Untersuchung weist zudem auf deutliche spezifische regionale Besonderheiten in der Verteilung hoch belasteter Beschäftigtengruppen sowie auf eine insgesamt deutlich höhere Prävalenz von Gratifikationskrisen in unserer Untersuchungsregion hin. Die Ergebnisse werden als ein Beispiel dafür gewertet, dass regional differenzierte Untersuchungen zum Zusammenhang zwischen Arbeit und Gesundheit ggü. solchen, die sich auf überregionale Durchschnittswerte beziehen, einen Erkenntniszugewinn bringen können.

description: Regarded as a promising alternative to spatially shaping matter, time-varying media can be seized to control and manipulate wave phenomena, including thermal radiation. Here, based upon the framework of macroscopic quantum electrodynamics, we elaborate a comprehensive quantum theoretical formulation that lies the basis for investigating thermal emission effects in time-modulated media. Our theory unveils new physics brought about by time-varying media: nontrivial correlations between thermal fluctuating currents at different frequencies and positions, thermal radiation overcoming the black-body spectrum, and quantum vacuum amplification effects at finite temperature. We illustrate how these features lead to striking phenomena and novel thermal emitters, specifically, showing that the time-modulation releases strong field fluctuations confined within epsilon-near-zero (ENZ) bodies, and that, in turn, it enables a narrowband (partially coherent) emission spanning the whole range of wavevectors, from near to far-field regimes.

description: If $X$ is an orientable, strongly minimal $PD_4$-complex and $π_1(X)$ has one end then it has no nontrivial locally-finite normal subgroup. Hence if $π$ is a 2-knot group then (a) if $π$ is virtually solvable then either $π$ has two ends or $π\congΦ$, with presentation $\langle{a,t}|ta=a^2t\rangle$, or $π$ is torsion-free and polycyclic of Hirsch length 4; (b) either $π$ has two ends, or $π$ has one end and the centre $ζπ$ is torsion-free, or $π$ has infinitely many ends and $ζπ$ is finite; and (c) the Hirsch-Plotkin radical $\sqrtπ$ is nilpotent.

description: An analytical work on intrinsic localized modes in a two-dimensional Heisenberg ferromagnet on the checkerboard lattice is presented. Taking advantage of an asymptotic method, the governing lattice dynamical equations are reduced to one (2+1) -dimensional nonlinear Schrödinger. In our work, we obtain two types of nonlinear localized mode solutions, namely, Brillouin zone center modes and Brillouin zone corner modes. The occurrence conditions for these intrinsic localized modes are given in detail. Especially, we find that the competition between the Dzialozinskii-Moriy interaction and the next-nearest neighbor interaction of the checkerboard ferromagnet has an effect on the local structure of the Brillouin zone corner acoustic mode.

Cyclic tridiagonal pairs, higher order Onsager algebras and orthogonal polynomials

description: The concept of cyclic tridiagonal pairs is introduced, and explicit examples are given. For a fairly general class of cyclic tridiagonal pairs with cyclicity N, we associate a pair of `divided polynomials'. The properties of this pair generalize the ones of tridiagonal pairs of Racah type. The algebra generated by the pair of divided polynomials is identified as a higher-order generalization of the Onsager algebra. It can be viewed as a subalgebra of the q-Onsager algebra for a proper specialization at q the primitive 2Nth root of unity. Orthogonal polynomials beyond the Leonard duality are revisited in light of this framework. In particular, certain second-order Dunkl shift operators provide a realization of the divided polynomials at N=2 or q=i.

description: This study was designed to assess the efficacy of Coriandrum sativum L. (CS) in preventing in vitro low density lipoprotein (LDL) oxidation mediated macrophage modification. Further, an in vivo study was also conducted to confirm upon the efficacy of CS seed extract in alleviating pathophysiological alterations of high cholesterol diet induced atherosclerosis in rats. Copper mediated cell free oxidation of LDL accounted for elevated indices of malondialdehyde (MDA), lipid hydroperoxide (LHP)and protein carbonyl (PC) and a progressive increment in conjugate diene (CD) levels whereas, reverse set of changes were recorded in presence of CS extract. Cell mediated LDL oxidation (using RAW 264.7 cells) accounted for lowered MDA production and oxidized LDL (Ox-LDL) mediated cell death in presence of CS extract and the same was attributed to its potent antioxidant and free radical scavenging potentials. High cholesterol fed atherogenic rats showed elevated lipid indices, evidences of LDL oxidation, plaque formation in thoracic aorta. The same was further validated with immunostaining of cell adhesion molecules and hematoxylin and eosin (HXE) staining. However, co-supplementation of CS to atherogenic rats recorded significant lowering of the above mentioned parameters further strengthening the claim that CS extract is instrumental in preventing onset and progression of atherosclerosis.

The distribution of CO$_2$ on Europa indicates an internal source of carbon

description: Jupiter's moon Europa has a subsurface ocean, the chemistry of which is largely unknown. Carbon dioxide (CO$_2$) has previously been detected on the surface of Europa, but it was not possible to determine whether it originated from subsurface ocean chemistry, was delivered by impacts, or was produced on the surface by radiation processing of impact-delivered material. We map the distribution of CO$_2$ on Europa using observations obtained with the James Webb Space Telescope (JWST) and find a concentration of CO$_2$ within Tara Regio, a recently resurfaced terrain. This indicates the CO$_2$ is derived from an internal carbon source. We propose the CO$_2$ formed in the internal ocean, though we cannot rule out formation on the surface by radiolytic conversion of ocean-derived organics or carbonates.
