description: It has recently been demonstrated that the dynamics of black holes at large $D$ can be recast as a set of non gravitational membrane equations. These membrane equations admit a simple static solution with shape $S^{D-p-2} \times R^{p,1}$. In this note we study the equations for small fluctuations about this solution in a limit in which amplitude and length scale of the fluctuations are simultaneously scaled to zero as $D$ is taken to infinity. We demonstrate that the resultant nonlinear equations, which capture the Gregory- Laflamme instability and its end point, exactly agree with the effective dynamical `black brane' equations of Emparan Suzuki and Tanabe. Our results thus identify the `black brane' equations as a special limit of the membrane equations and so unify these approaches to large $D$ black hole dynamics.

description: The mathematics and physics of each of the three aspects of magnetic field evolution -- topology, energy, and helicity -- is remarkably simple and clear. When the resistivity $η$ is small compared to an imposed evolution, $a/v$, timescale, which means $R_m\equivμ_0va/η>>1$, magnetic field line chaos dominates the evolution of field-line topology in three-dimensional systems. Chaos has no direct role in the dissipation of energy. A large current density, $j_η\equiv vB/η$, is required for energy dissipation to be on a comparable time scale to the topological evolution. Nevertheless, chaos plus Alfvén wave damping explain why both timescales tend to be approximately an order of magnitude longer than the evolution timescale $a/v$. Magnetic helicity is injected onto tubes of field lines when boundary flows have vorticity. Chaos can spread but not destroy magnetic helicity. Resistivity has a negligible effect on helicity accumulation when $R_m>>1$. Helicity accumulates within a tube of field lines until the tube erupts and moves far from its original location.

description: This text discusses controversies surrounding theoretical, practical, and political implications of "actor-network theory" ("ANT"). Since its inception around 1980, "ANT" has been applied in an immense number of empirical studies, both within and outside the field of science and technology studies. But it was also rejected as radical chic without substance and/or as theoretically and politically unacceptable in perhaps as many instances as it was accepted. Implicit in both the application and critique of "ANT" is the assumption that it can be treated as a "black-boxed" set of notions and rules containing certain strengths and weaknesses. Proposing to treat black-boxed "ANT" as useful provocation, I discuss what this kind of "ANT" can and cannot do for me in my own empirical research on energy efficiency in buildings. In the second part of the text I turn from "black boxed" and well-defined "ANT" to "ANT in the making". In recent and ongoing work Bruno Latour, John Law, Annemarie Mol, Vicky Singleton, and others (in alphabetic order) answer to critiques of "ANT"s" political implications. The authors share an interest in the development of a non-essentialist foundation of politics, which neither turns into crude functionalism nor into hollow relativism. Concluding this text, two of the proposals made here, "political ecology" and "ontological politics", are compared and discussed in the context of my own research.

Savremeni razvoj SUS motora, posebno u slučaju sportskih automobila, nameće potrebu za postizanjem maksimalne snage, što pak ekstremno povećava opterećenje pojedinih delova klipa. Pokazalo se da tvrdoća i otpornost na habanje, inače svojstveni legurama aluminijuma, na ovako visokim temperaturama i ekstremnim eksploatacionim uslovima, nisu zadovoljavajuće. Ideja je da se najopterećeniji delovi klipa zaštite kompozitima sa aluminijumskom matricom, što što bi predstavljalo rešenje ovog problema. Cilj ovog rada je da izvrši pregled postignutih rezulata istraživanja u ovoj oblasti.

description: Purpose: Multiple sclerosis (MS) is a chronic disease of the central nervous system that disproportionately affects women, with typical onset during reproductive age. Several disease-modifying therapies (DMTs) are FDA-approved to slow disease progression, but are not indicated for use during pregnancy. Our objective was to describe trends over time (2010–2019) in monthly point prevalence of DMT use among reproductive-age women, overall and by generic name. Methods: This study used administrative claims data from the US during 2009–2019 to identify women age 15–44 with MS and continuous insurance coverage for ≥12 months. DMTs were identified using prescription fills and procedural claims for alemtuzumab, daclizumab, dimethyl fumarate, fingolimod, glatiramer acetate, interferon beta, mitoxantrone, natalizumab, ocrelizumab, and teriflunomide. Monthly prevalent use was defined as ≥1 days' supply of a DMT in the month. Age- and region-standardized monthly prevalence was estimated nonparametrically. Results: Among 42 281 reproductive-aged women over 818 179 person-months, DMT use increased from a minimum monthly prevalence of 49.3% (February, 2011) to a maximum of 58.7% (April, 2019). In 2010, prevalence of injectable DMTs was 43.1% compared to 2.5% for oral DMTs; by 2014, however, oral DMTs (26.5%) surpassed injectable DMTs (23.7%) as the most common route of administration. In the most recent data available (December, 2019), the most common DMTs were dimethyl fumarate, glatiramer acetate, and fingolimod. Conclusions: DMT use among reproductive-aged women has rapidly evolved during the past decade. Collaborative treatment decision making between women with MS and clinicians may help optimize MS care and improve DMT uptake during reproductive years.
On transverse single-spin asymmetries in $D$-meson production at the SPD NICA experiment

Year: 2022
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In the present study we are interested in the Sivers effect in process $p^{\uparrow}p\to DX$. We calculate the transverse single-spin asymmetry (TSSA) of $D$-meson production within two phenomenological models, namely the Generalized Parton Model (GPM) and it's Colour Gauge-Invariant formulation (CGI-GPM), which takes into account the transverse momenta of initial partons. The last one allows us to study process-independent Sivers functions. To predict production cross-section of $D$-mesons we use a fragmentation approach with scale-independent Peterson fragmentation function, taking in mind nonzero masses of $c$-quark and $D$-mesons. Estimates for the TSSAs, as a function of transverse momentum and Feynman variable $x_F$ of $D$-meson, within the conditions of the planned SPD NICA experiment are presented for the first time.

description: We propose a theoretical scheme for quantum sensing of temperature close to absolute zero in a quasi-one-dimensional Bose-Einstein condensate (BEC). In our scheme, a single-atom impurity qubit is used as a temper-ature sensor. We investigate the sensitivity of the single-atom sensor in estimating the temperature of the BEC. We demonstrate that the sensitivity of the temperature sensor can saturate the quantum Cramer-Rao bound by means of measuring quantum coherence of the probe qubit. We study the temperature sensing performance by the use of quantum signal-to-noise ratio (QSNR). It is indicated that there is an optimal encoding time that the QSNR can reach its maximum in the full-temperature regime. In particular, we find that the QSNR reaches a finite upper bound in the weak coupling regime even when the temperature is close to absolute zero, which implies that the sensing-error-divergence problem is avoided in our scheme. Our work opens a way for quantum sensing of temperature close to absolute zero in the BEC.

description: For about 20 years, a rather wide range of conceptual approaches to the social study of science and technology have emerged which have occasionally been labelled "postconstructivist". Although these conceptions differ in various respects, they have in common a twofold opposition: against traditional representationalist realism as well as "classical" social constructivism established by the "sociology of scientific knowledge" (SSK). In order to escape the pitfalls of both these views (and to overcome the familiar, yet unfruitful opposition between them), postconstructivist perspectives understand and study the sciences primarily in term of their situated material and discursive practices. The present article starts with a brief retrospect on why and how since the mid-1980s postconstructivist trends have questioned not only rationalist and realist accounts but also the conceptual foundations and background assumptions of SSK s claim to explain sociologically the content of science. Subsequently, the central features of a postconstructivist perspective in science studies are outlined, referring to the key concepts of "knowledge", "practice", and "performativity". The fruitfulness of a theoretical approach focusing on scientific practices is illustrated using the example of the increasingly important issue of scientific non-knowledge: In the same way that knowledge is not to be comprehended as simply the mental "possession" of a knower, non-knowledge is not merely the lack thereof but an (unrecognised) implication of materially and socially situated research practices. Finally, it is emphasised that postconstructivist science studies should not be misunderstood as claiming (as do realism and constructivism) to provide a meta-theoretical explanation or legitimation of science. Instead, postconstructivism should be conceived as a situated critical effort to challenge one-sided accounts of scientific knowledge and foster more self-reflective research practices.

description: The correlation between the jet power and accretion disk luminosity is investigated and analyzed with our model for 7 samples of low luminosity active galactic nuclei (LLAGNs). The main results are: (1) the power-law correlation index ($P_{jet} \propto L_{disk}^μ$) typically ranges $μ=0.4-0.7$ for the LLAGN samples, and there is a hint of steep index for the LLAGN sample which hosted by a high fraction of elliptical galaxies, and there are no significant correlation between the $μ$ and the LLAGN types (Seyfert, LINER); (2) for $μ\approx$1, as noted in Liu et al., the accretion disk dominates the jet power and the black hole (BH) spin is not important, for the LLAGN samples studied in this paper we find that the $μ$ is significantly less than unity, implying that BH spin may play a significant role in the jet power of LLAGNs; (3) the BH spin-jet power is negatively correlated with the BH mass in our model, which means a high spin-jet efficiency in the `low' BH-mass LLAGNs; (4) an anti-correlation between radio loudness and disk luminosity is found, which is apparently due to the flatter power-law index in the jet-disk correlation of the LLAGNs, and the radio loudness can be higher in the LLAGNs than in luminous AGNs/quasars when the BH spin-jet power is comparable to or dominate over the accretion-jet power in the LLAGNs. The high radio-core dominance of the LLAGNs is also discussed.

description: Field Epidemiology training in Ethiopia was started in 2009 to produce competent and skillful Epidemiologists, cadres of PHEM officers who promote and assist evidence-based decision making. The program is quite different from traditional epidemiology; unlike other public health students, the residents of field epidemiology spend 75% of the two-year study period in different field sites so that they can practically apply what they learned in the class and become acquainted with how the system is functioning and what the existing gaps are that hamper the proper functioning of the system. In doing so, they have a chance to apply their knowledge and skill. During this two-year residency period I have been able to accomplished most of the outputs that was expected from me. My first work was an outbreak investigation. Two outbreaks were investigated. The first one was AWD outbreak investigation. It was conducted in Kombolcha Woreda, East Harargie zone, Oromia. A total of 63 study participants (21 cases and 42 controls) were enrolled in the study. Then Scabies outbreak investigation was done in Dire Dawa City Administration, by recruiting 96 study participants (32 cases and 64 controls). The second work or output was surveillance data analysis report. The report touched a three year (or 2013-2016) bacillary dysentery cases data analysis in Addis Ketema sub city of Addis Ababa. Surveillance system Evaluation was also conducted in Addis Ketema sub city, August 2017.The AFP and Acute Malnutrition surveillance was evaluated as a proxy for the rest of the surveillance system. Health profile description report was done as a fourth output. It was conducted in one of the districts of Addis Ketema sub city, woreda 3 administrative unit. One manuscript for peer reviewed journals and one abstract were prepared and incorporated as 5th & 6th outputs in this document. A summary narrative report of rapid meher assessment again done in 5 zones and 16 visited woredas of Tigray Region from 21 Nov. to 8 Dec. 2017. Finally, Proposal for epidemiologic research project was prepared on Knowledge, Attitude and Practice of Scabies among local population of Raya-Alamata Woreda, Southern Tigray Regional Zone-2017.

description: Ion-selective channels play a key role in physiological processes and are used in many technologies. While biological channels can efficiently separate same-charge ions with similar hydration shells, it remains a challenge to mimic such exquisite selectivity using artificial solid-state channels. Although, there are several nanoporous membranes that show high selectivity with respect to certain ions, the underlying mechanisms are based on the hydrated ion size and/or charge. There is a need to rationalize the design of artificial channels to make them capable of selecting between similar-size same-charge ions, which in turn requires understanding of why and how such selectivity can occur. To address this issue, we study angstrom-scale artificial channels made by van der Waals assembly, which are comparable in size with typical ions and carry little residual charge on channel walls. This allows us to exclude the first-order effects of steric and Coulomb-based exclusion. We show that the studied two-dimensional angstrom-scale capillaries can distinguish between same-charge ions with similar hydrated diameters. The selectivity is attributed to different positions occupied by ions within the layered structure of nanoconfined water, which depend on the ion-core size and differ for anions and cations. The revealed mechanism points at possibilities of ion separation beyond the simple steric sieving.

description: We experimentally study resonant interactions of oblique surface gravity waves in a large basin. Our results strongly extend previous experimental results performed mainly for perpendicular or collinear wave trains. We generate two oblique waves crossing at an acute angle, while we control their frequency ratio, steepnesses and directions. These mother waves mutually interact and give birth to a resonant wave whose properties (growth rate, resonant response curve and phase locking) are fully characterized. All our experimental results are found in good quantitative agreement with four-wave interaction theory with no fitting parameter. Off-resonance experiments are also reported and the relevant theoretical analysis is conducted and validated.

description: Background: Shigellosis is the most common cause of outbreak of bloody diarrhea worldwide with secondary infection rates as high as 40% in the household and case fatality rate of 15-20%. Method: Unmatched 1:2 case-control study was conducted from July 2- 10, 2015. Data were collected using Semi- structured questionnaire. Stool and drinking water sample were also collected, transported and examined as per standard Microbiologic procedures. Data were entered and analyzed in Epiinfo 7 and SPSS, ARC GIS. To measure the significance of association we constructed odds ratio, 95% CI. Results: A total of 86 dysentery cases with no death were identified. The median age of case and control were 25 (Range, 2- 62 years). The overall attack rate (AR) was 2.3 per 1000 (86) population. Highest attack rate was observed among 15- 44 years (2.6 per 1000), highest cases were registered from Arib Gebeya Kebele 4.4 per 1000 population .In multivariate analysis the statically significant variables are no access to latrine AOR=7.2 (95% CI: 1.8 – 29.4), washing hands without soap AOR 5.1=(95%CI: 2.4 -11.1),not washing of hands after using toilet AOR=5.6 (95%CI: 2.5– 12.1), open filled dispose of household garbage AOR 9.2=(95%CI: 3.7 – 22), were risk factors for dysentery diseases but treating water with chemical /boil AOR=0.16 (95%CI :0.06 – 0.39) were protective factors.50%.Stool samples collected for microbiological culture were positives for shigella dysentery and water specimens collected from spring and pipeline was positive for coliform count at 370c/48 hrs /100ml was >180,Eshenerichia Coil Type 1 present and commented as Bacteriologically the water is not potable and chlorination necessary. Conclusion: There was an outbreak of dysentery in Dera woreda due to shigella dysentery, the most likely common source of the epidemic was contamination of water. Therefore, provision of safe drinking water supply and raising community awareness about hygienic practices to control diarrheal disease is necessary.

description: Quantum control is valuable for various quantum technologies such as high-fidelity gates for universal quantum computing, adaptive quantum-enhanced metrology, and ultra-cold atom manipulation. Although supervised machine learning and reinforcement learning are widely used for optimizing control parameters in classical systems, quantum control for parameter optimization is mainly pursued via gradient-based greedy algorithms. Although the quantum fitness landscape is often compatible with greedy algorithms, sometimes greedy algorithms yield poor results, especially for large-dimensional quantum systems. We employ differential evolution algorithms to circumvent the stagnation problem of non-convex optimization. We improve quantum control fidelity for noisy system by averaging over the objective function. To reduce computational cost, we introduce heuristics for early termination of runs and for adaptive selection of search subspaces. Our implementation is massively parallel and vectorized to reduce run time even further. We demonstrate our methods with two examples, namely quantum phase estimation and quantum gate design, for which we achieve superior fidelity and scalability than obtained using greedy algorithms.

description: We consider ultracold atoms inside a ring optical cavity that supports a single plane-wave mode. The cavity field, together with an external coherent laser field, drives a two-photon Raman transition between two internal pseudo-spin states of the atom. This gives rise to an effective coupling between atom's pseudo-spin and external center-of-mass (COM) motion. For the case of a single atom inside the cavity, We show how the spin-orbit coupling modifies the static and dynamic properties of the Jaynes-Cummings (JC) model. In the case of many atoms in thermodynamic limit, we show that the spin-orbit coupling modifies the Dicke superradiance phase transition boundary and the non-superradiant normal phase may become reentrant in some regimes.

description: This presentation is a part of a course at the basic level at Stockholm University. It is a course which was supported by the Centre for Canadian Studies of Stockholm University. The course is designed to introduce students to a variety of aspects related to the history, culture and literature of Canadian society. It also tackles the bilingual aspect of Canadian society and helps students to discuss issues that are relevant in Canada. The course then looks at the challenges facing Canada in the 21st Century with focus on immigration and multiculturalism, the First Nations, gender equality, specific regions in Canada with special emphasis on Québec, and Canada's cultural identity.
 The lecture gives an overview of the history of the French Canadians between 1700 and 1867. In 1867, the Confederation of Canada was officially created but how was it possible? What are the implications on the Canadian identity?

description: A dark photon is predicted by several well-motivated Standard Model extensions and UV completions. Here the most general effective field theory up to dimension-six operators describing the interactions of a massless dark photon with all Standard Model particles is considered. This captures the predictions of a generic model featuring this type of vector boson at sufficiently low energies. In such framework the thermal production rate of dark photons is computed at leading order, including the contributions of all SM particles. The corresponding cosmological yield of the dark photon and its contribution to the effective number of neutrinos are also calculated. These predictions satisfy the current observational bounds and will be tested by future measurements.

description: The article takes issue with recent influential work on the paradigmatic relevancy of technologically induced modes of communication and sociality on the financial markets. According to Karin Knorr Cetina and Urs Bruegger, the technological infrastructure of the global financial markets engenders novel forms of sociality and social integration: intersubjectivity with non-present others and (post)sociality with (imagined) objects. The article differentiates these hypotheses by way of confronting them with results from interviews conducted with financial market professionals such as asset managers and financial analysts. They reveal that financial professionals attribute the role of technology a varying meaning and engage in divergent technological practices depending on their market positionality: while, for instance, intraday traders report on an intimate and quasi-social relationship with the technologically institutionalized "object" of the market, equity analysts display a more distanced stance toward the market and attribute the technological nature of mass communication (especially the real-time circulation of information) paramount importance. In conclusion the paper calls for a nuanced and contextualized understanding of the impact of technology upon changing social relations.

description: Globalization (GLB), one of the characteristics that define the beginning of 21st century has received considerable attention in the past two decades. Its effects are suggested to impact on most aspects of economic, political and social life including that of public health. Despite being current national and global concern with such many potential impacts, yet limited attention so far has been given to its effect on health, particularly in developing countries. Therefore, this empirical study aimed to examine the relationship between GLB and health status outcome in Sub- Saharan Africa (SSA) to contribute to policy making dialogue that can exploits the possible benefits and mitigate GLB's detrimental effects. The study was confined to the period of 1960-2000 for cross-section of twenty-six SSA. Two latest decades of contemporary GLB were measured with preceding two decades for comparison. A Balanced panel data (time series- Cross section) analytic method was used for its advantage over pure time series and pure cross-section study. Measures of GLB and the traditionally recognized determinant of health were used as an independent variable while Infant Mortality Rate (IMR) was used as a dependent measure of health. The analysis was made using LIMDEP econometric analysis software for its reach varieties of panel data analytic procedures. A 0.05 alpha level was used to report the significant values. The result revealed the existence of correlations between the presumed determinant of health and measure of health status. Among the determinant factors, export of goods and services (p=0.018), Primary school enrollment of females (p=0.030) and emigration (p=0.020) were found to have significant, inverse relationship with IMR. On the other hand, import of goods and services (p=0.042), tourism (p=0.012), and surprisingly, urbanization (p=0.038) were found to have a positive, significant association. Whilst possible recommendations were suggested from these findings, the effect of separate dimensions of GLB on health and the other integral features like cultural dimensions of GLBs' influence on health are recommended for further research in the region.

description: Introduction: continual mutations of the sars-cov-2 virus, with the possibility of reinfection or reactivation of the virus, can lead to a further spread of the virus and consequently new infection periods. The state of pernambuco, brazil, has faced many adversities amidst the pandemic, requiring studies and new spatiotemporal techniques to understand the pandemic development and planning actions to reverse the current situation.Objective: the aim was to evaluate the mortality and lethality trends of covid-19 from april 2020 to june 2021 in the state of pernambuco, brazil, with the division into two periods according to the waves of infection to date (1st period and 2nd period).Methods: an ecological time-series study was carried out with population data from the pernambuco state health department. We collected the number of confirmed cases and deaths for covid-19. The trends were analyzed according to the prais-winsten regression model in two moments from march 2020 to september 2020 and the second from october 2021 to June 2022. Differences were considered significant when p<0.05.Results: the state of pernambuco had 581,594 confirmed cases of covid-19, where 51,370 were severe cases, and 530,224 were mild cases, in addition to 18,444 deaths. Given the trends analyzed, mortality was increasing in the second period (april/2020 to june/2021), while lethality decreased in the first period and was stationary in the second period.Conclusion: this study found an increasing trend in mortality of covid-19 in the state of pernambuco, brazil in the second period, highlighting an urgent need to develop surveillance measures as well as public policies for vulnerable populations, in addition to continuing preventive measures.

description: Background: Endometrial cancer (EC) shares risk factors (e.g. obesity) with cardiovascular disease (CVD), yet little research has investigated CVD diagnoses among EC survivors. We aimed to describe the burden of CVD diagnoses among older women with EC compared to women without a cancer history. Methods: Women aged 66+ years with an EC diagnosis during 2004–2017 (N = 44,386) and matched women without cancer (N = 221,219) were identified in the SEER-Medicare linked data. An index date was defined as the cancer diagnosis date of the EC case in that matched set. ICD-9/10 diagnosis codes were used to define CVD outcomes in the Medicare claims. Prevalent CVD was identified using diagnosis codes in the year before the index date. Hazard ratios (HRs) for incident CVD diagnoses after the index date were estimated using multivariable Cox proportional hazards regression. Women with a prevalent CVD were excluded from incidence analyses for that outcome. Results: Compared to women without cancer, women with EC had a higher prevalence of CVD diagnoses at the index date. In analyses beginning follow-up at 1 year post-index date, EC survivors had an increased risk of incident CVD diagnoses including ischemic heart diseases (HR = 1.73; 95% CI: 1.69–1.78), pulmonary heart disease (HR = 1.95; 95% CI: 1.88–2.02), and diseases of the veins and lymphatics (HR = 2.71; 95% CI: 95% CI: 2.64–2.78). Risk of CVD diagnoses among women with EC was also elevated within the first year post-index date. Conclusions: Management of pre-existing CVD and monitoring for incident CVD may be critical during EC treatment and throughout long-term survivorship.

description: We study optical response of a resonant medium possessing nonlinear coupling to external field driven by a few-cycle pump pulse sequence. We demonstrate the possibility to directly produce unipolar half-cycle pulses from the medium possessing an arbitrary nonlinearity, by choosing the proper pulse-to-pulse distance of the pump pulses in the sequence. We examine the various ways of the shaping of the medium response using different geometrical configurations of nonlinear oscillators and different wavefront shapes for the excitation pulse sequence. Our approach defines a general framework to produce unipolar pulses of controllable form.
