description: Compound weather events may lead to extreme impacts that can affect many aspects of society including agriculture. Identifying the underlying mechanisms that cause extreme impacts, such as crop failure, is of crucial importance to improve their understanding and forecasting. In this study, we investigate whether key meteorological drivers of extreme impacts can be identified using the least absolute shrinkage and selection operator (LASSO) in a model environment, a method that allows for automated variable selection and is able to handle collinearity between variables. As an example of an extreme impact, we investigate crop failure using annual wheat yield as simulated by the Agricultural Production Systems sIMulator (APSIM) crop model driven by 1600 years of daily weather data from a global climate model (EC-Earth) under present-day conditions for the Northern Hemisphere. We then apply LASSO logistic regression to determine which weather conditions during the growing season lead to crop failure. We obtain good model performance in central Europe and the eastern half of the United States, while crop failure years in regions in Asia and the western half of the United States are less accurately predicted. Model performance correlates strongly with annual mean and variability of crop yields; that is, model performance is highest in regions with relatively large annual crop yield mean and variability. Overall, for nearly all grid points, the inclusion of temperature, precipitation and vapour pressure deficit is key to predict crop failure. In addition, meteorological predictors during all seasons are required for a good prediction. These results illustrate the omnipresence of compounding effects of both meteorological drivers and different periods of the growing season for creating crop failure events. Especially vapour pressure deficit and climate extreme indicators such as diurnal temperature range and the number of frost days are selected by the statistical model as relevant predictors for crop failure at most grid points, underlining their overarching relevance. We conclude that the LASSO regression model is a useful tool to automatically detect compound drivers of extreme impacts and could be applied to other weather impacts such as wildfires or floods. As the detected relationships are of purely correlative nature, more detailed analyses are required to establish the causal structure between drivers and impacts.

description: We use a new mechanism for generating a Fayet-Iliopoulos term in supergravity, which is not associated to an R symmetry, to construct a semi-realistic theory of slow-roll inflation for a theory with the same Kähler potential and superpotential as the KKLT string background (without anti-D3 branes). In our model, supersymmetry must be broken at a high scale in a hidden sector to ensure that the cutoff of the effective field theory is above the Hubble scale of inflation. The gravitino has a super-EeV mass and supersymmetry breaking is communicated to the observable sector through gravity mediation. Some mass scales of the supersymmetry-breaking soft terms in the observable sector can be parametrically smaller than the SUSY breaking scale. If a string realization of the new FI term were found, our model could be the basis for a low energy effective supergravity description of realistic superstring models of inflation.

description: A major public health problem in developing countries including Ethiopia is related with poor sanitation and hygiene. Globally , over 2.5 billion people are still without access to improved sanitation. In 2010, 15% of the population still practice open defecation . The main objective of this study was to compare the latrine utilization rate and identify determinant factors among kebeles implementing and not implementing Urban Community Led Tot al Sanitation and Hygiene (UCLTSH) in Hawassa town. Comparative cross sectional study design was carried out in Hawassa town in 704 households in 3 kebeles undertaken UCLTSH and in randomly selected comparison 3 kebeles where UCLTSH was not implemented. Da ta entry and cleaning was undertaken by using EPI - info version 3.5.3 and analyzed using SPSS version 20. Multivariate logistic regression was used for independent variables with statistical significant association in bi - variate analysis. In this study , maj ority of the households 318 (90.3%) of UCLTSH impl ementers and 299 (85.4%) of non - implementers utilized latrines. The odds of latrine utilization were 1.59 times among households implementing UCLTSH compared with that among non UCLTSH [OR 1.59, 95% CI (1.0 0, 2.53)]. In relation to functional latrine , it was one of the factor s affecting latrine utilization [AOR 28.26, 95% CI (13.03, 61.27)]. This study shows communities implement ing urban community led total sanitation and hygiene was better in latrine utili zation and having latrine facility than non - implementers . It is recommended that the town health office and municipality should expand the UCLTSH to other kebeles of the town .

description: We systematically study the hyperon global polarization's sensitivity to the collision systems' initial longitudinal flow velocity in hydrodynamic simulations. By explicitly imposing local energy-momentum conservation when mapping the initial collision geometry to macroscopic hydrodynamic fields, we study the evolution of systems' orbital angular momentum (OAM) and fluid vorticity. We find that a simultaneous description of the $Λ$ hyperons' global polarization and the slope of pion's directed flow can strongly constrain the size of longitudinal flow at the beginning of hydrodynamic evolution. We extract the size of the initial longitudinal flow and the fraction of orbital angular momentum in the produced QGP fluid as a function of collision energy with the STAR measurements in the RHIC Beam Energy Scan program. We find that there is about 100-200 $\hbar$ OAM that remains in the mid-rapidity fluid at the beginning of hydrodynamic evolution. We further exam the effects of different hydrodynamic gradients on the spin polarization of $Λ$ and $\barΛ$. The gradients of $μ_B/T$ can change the ordering between $Λ$'s and $\barΛ$'s polarization.

description: The co-occurrence of warm spells and droughts can lead to detrimental socio-economic and ecological impacts, largely surpassing the impacts of either warm spells or droughts alone. We quantify changes in the number of compound warm spells and droughts from 1979 to 2018 in the Mediterranean Basin using the ERA5 data set. We analyse two types of compound events: 1) warm season compound events, which are extreme in absolute terms in the warm season from May to October and 2) year-round deseasonalised compound events, which are extreme in relative terms respective to the time of the year. The number of compound events increases significantly and especially warm spells are increasing strongly – with an annual growth rates of 3.9 (3.5) % for warm season (deseasonalised) compound events and 4.6 (4.4) % for warm spells –, whereas for droughts the change is more ambiguous depending on the applied definition. Therefore, the rise in the number of compound events is primarily driven by temperature changes and not the lack of precipitation. The months July and August show the highest increases in warm season compound events, whereas the highest increases of deseasonalised compound events occur in spring and early summer. This increase in deseasonalised compound events can potentially have a significant impact on the functioning of Mediterranean ecosystems as this is the peak phase of ecosystem productivity and a vital phenophase.

description: Background Worldwide, cervical cancer is second most common health problem in women. Approximately 80% of cervical cancer occurs in developing countries. The magnitude of the problem has been under recognized and under prioritized compared to health priority such as HIV/AIDS, tuberculosis and malaria. Most cases of women with cervical cancer in sub-Saharan Africa present at advanced stage of the diseases, when treatment is ineffective or not available. Therefore the aim of this study was to assess the level of knowledge of women on cervical cancer and factors affecting their knowledge for cervical cancer in women who are visiting health facility which is found in Gulele sub-city Addis Ababa. Methods A facility based cross sectional study was conducted from January-April 2015 in Addis Ababa Gulele sub city. A total of 508 study participants whose age was 21-64 years were participated in the study. Astructured interview administered questionnaire was used to assess information. SPSS window version 21 was used for data entry and analysis. Result Of all the respondents 190 (37.4) were above average knowledge on cervical cancer. The knowledge of women on cervical cancer was found to be low. Education about the disease must include information on disease symptoms, treatment options, stages of curacy and prevention methods. Conclusions The result of this study revealed that knowledge of women on cervical cancer was low. The minister of health and stakeholders should have to give focus on the national policy of non-communicable prevention strategy to be effectively implemented in health facility. Client cantered regular health education about non-communicable disease like cervical cancer in health facility is important to increase women knowledge on the disease.

description: A novel transport phenomenon is identified that is induced by inertial Brownian particles which move in simple one-dimensional, symmetric periodic potentials under the influence of both a time periodic and a constant, biasing driving force. Within tailored parameter regimes, thermal equilibrium fluctuations induce the phenomenon of absolute negative mobility (ANM), which means that the particle noisily moves {\it backwards} against a small constant bias. When no thermal fluctuations act, the transport vanishes identically in these tailored regimes. There also exist parameter regimes, where ANM can occur in absence of fluctuations on grounds which are rooted solely in the complex, inertial deterministic dynamics. The experimental verification of this new transport scheme is elucidated for the archetype symmetric physical system: a convenient setup consisting of a resistively and capacitively shunted Josephson junction device.

description: The present work focuses on the analysis of the myths that Plato narrates in some of his famous works. Firstly there are some references to the life and work of Plato while later the way that Plato dealt with myths. It must be pointed out that on the one land, he does not accept them, especially because of their connections to the ancient greek traditional religion but on the other land, it is true that up to a point he does not stop regarding them as a useful tool for the conclusions drawing concerning his philosoplical ideas. In the third level there is an analysis of the categorization of the varuius myths in Plato’s works. This is done based on a series of criteria such as the thematic origin of those myths and the chronological order of the works. Finally in the forth chapter, there is the analysis of each of the three myths meaning the myth of Er, Phaedon and Gorgias. Through this analysis the goal is to stress the framework of the ideas and philosophical teaching that plato attempts to display.

description: Ant enatal depressive disorders are serious health problems and pose multiple dangers to both the mother and her fetus, however, not given due attention. They are found with significantly higher prevalence rates in low income countries and associated with socio - economic and socio - cultural factors predominantly . The main objective of this study was to assess the prevalence of antenatal depressive disorders and associated factors among Adama Hospital A ntenatal clinic attendants. A hospital based cross sectional study was conducted from March 1st to April 21 st , 2011 at Adama Hospital, Adama, Ethiopia . A bout 231 preg nant women were in terviewed using systematic sampling method . Pretested B eck D epression I nventory (BDI) structured questionnaire was used to collect data. The presence of depressive disorders was explained by the sum of BDI items scored 21 and above. And, data entry was done by SPSS version 15 and analyzed using logistic regression . The mean age was 26.32 ±0.24 . About 56.7 % were in third trimester and 45 % were nul l ipar ous . Regarding pattern of current pregnancy, unwanted pregnancy accounted 42 % . Prevalence r ate of antenatal depressive disorders was found to be 31.2 % . P revious abortion [AOR=2.86 , CI (1.13, 7.24)], fear of pregnancy complications [AOR= 3.49 , CI (2.21, 22.17)], economic problem [AOR=9.52 , CI (2.68, 33.78)] and unwanted pregnancy [AOR=6.99 , CI (2. 21, 22.17) and marital conflict [AOR= 22.68 , CI(3.61, 142.33 ] were found to have strong association with depressive disorders. The p revalence of antenatal depressive disorders was high at the study area. Psychosocial factors, economic problems and obstetric features were significantly associated with maternal depressive disorder . Adama Hospital should integrate mental health service with existing antenatal clinic service . In addition, screening of antenatal care (ANC) attendants for potential risk factors of antenatal depressive disorders could be crucial to hamper the impending dangers through early detection.

description: We study the temporal evolution of coronal loops using data from the Solar X-ray Imager (SXI) on board of GOES-12. This instrument allows us to follow in detail the full lifetime of coronal loops. The observed light curves suggest three somewhat distinct evolutionary phases: rise, main, and decay. The durations and characteristic timescales of these phases are much longer than a cooling time and indicate that the loop-averaged heating rate increases slowly, reaches a maintenance level, and then decreases slowly. This suggests that a single heating mechanism operates for the entire lifetime of the loop. For monolithic loops, the loop-averaged heating rate is the intrinsic energy release rate of the heating mechanism. For loops that are bundles of impulsively heated strands, it is an indication of the frequency of occurrence of individual heating events, or nanoflares. We show that the timescale of the loop-averaged heating rate is proportional to the timescale of the observed intensity variation. The ratios of the radiative to conductive cooling times in the loops are somewhat less than 1, putting them intermediate between the values measured previously for hotter and cooler loops. Our results provide further support for the existence of a trend suggesting that all loops are heated by the same mechanism, or that different mechanisms have fundamental similarities (e.g., are all impulsive or are all steady with similar rates of heating).

description: Scaling analysis of heart rate time series has emerged as an useful tool for assessment of autonomic cardiac control. We investigate the heart rate time series of ten athletes (five males and five females), by applying detrended fluctuation analysis (DFA). High resolution ECGs are recorded under standardized resting conditions over 30 minutes and subsequently heart rate time series are extracted and artefacts filtered. We find three distinct regions of scale-invariance, which correspond to the well-known VLF, LF, and HF bands in the power spectra of heart rate variability. The scaling exponents alpha are alphaHF: 1.15 [0.96-1.22], alphaLF: 0.68 [0.57-0.84], alphaVLF: 0.83[0.82-0.99]; p<10^-5). In conclusion, DFA scaling exponents of heart rate time series should be fitted to the VLF, LF, and HF ranges, respectively.

description: Introduction: Use of substances such as alcohol, khat and tobacco has become one of the rising major public health and socio-economic problems worldwide. Many people at risk for or already infected with HIV abuse alcohol, contributing to the difficulties in preventing the spread of the infection and treating infected patients. Objective: The objective of the study was to assess prevalence of Substance use and associated factors among Retro Viral Infected (RVI) Patients on Antiretroviral Treatment (ART) at Assela Teaching Hospital, Assela Ethiopia. Methodology: A cross sectional study was conducted from June to August 2016 among 418 RVI patients who were on ART follow up at Assela Teaching Hospital. The participants were selected systematic random sampling. Socio demographic data and other relevant data was collected using semi structured questionnaire. The data was coded, cleaned and entered using Epi Info 3.5.3 then exported to Statistical Package for the Social science (SPSS) version 21 for further analysis. Descriptive statistics and logistic regression analysis was used. Results: The prevalence of substance use at least once in their lifetime among RVI patient was 27.5% whereas the prevalence of current substance use was 3.8% and Alcohol was predominantly abused drug. Alcohol was the being male and friend or family substance use was strong predictors of substance abuse among the respondents. Conclusion and recommendation: This study revealed that the prevalence of substance use among RVI patient was significant. We recommend that awareness creation about the influence of substance use on HIV by health professionals have invaluable benefit.

description: Kagom${é}$ lattice is a fertile platform for topological and intertwined electronic excitations. Recently, experimental evidence of an unconventional charge density wave (CDW) is observed in a Z2 kagom${é}$ metal AV$_{3}$Sb$_{5}$ (A= K, Cs, Rb). This observation triggers wide interests on the interplay between frustrated crystal structure and Fermi surface instabilities. Here we analyze the lattice effect and its impact on CDW in AV$_{3}$Sb$_{5}$. Based on published experimental data, we show that the CDW induced structural distortions is consistent with the theoretically predicted inverse star-of-David pattern, which preserves the $D_{6h}$ symmetry in the kagom${é}$ plane but breaks the sixfold rotational symmetry of the crystal due to the phase shift between kagom${é}$ layers. The coupling between the lattice and electronic degrees of freedom yields a weak first order structural transition without continuous change of lattice dynamics. Our result emphasizes the fundamental role of lattice geometry in proper understanding of unconventional electronic orders in AV$_{3}$Sb$_{5}$.

description: In addition to nitric oxide and carbon monoxide, hydrogen sulfide (H 2 S) is the third gasotransmitter in mammals. It is synthesized from L-cysteine by cystathionine β-synthase, cystathionine γ-lyase or by sequential action of alanine aminotransferase and 3-mercaptopyruvate sulfur transferase. Although initially it was suggested that in the vascular wall H 2 S is synthesized only by smooth muscle cells and relaxes them by activating ATP-sensitive potassium channels, more recent studies indicate that H 2 S is synthesized in endothelial cells as well. The physiological functions of H 2 S are mediated by different molecular targets, such as different ion channels and signaling proteins. Endogenous H 2 S is involved in the regulation of many physiological processes in the cardiovascular system including the regulation of vascular tone, blood pressure and inhibits atherogenesis. Many new technologies have been developed to detect endogenous H 2 S production, and novel H 2 S-delivery compounds have been invented to aid therapeutic intervention of diseases related to abnormal H 2 S metabolism. The primary purpose of this review was to provide an overview of the role of H 2 S in the blood vessel, methods of endogenous production detections and common ion channels used to produce its biological effect describe its beneficial effects.

description: The aim of the paper is a comparative study of the myth of “The Odyssey”, as it is presented in the homeric epic and in two infantile books, a greek and a spanish one. The study is constructed in the light of semiotics and examines the narrative and pictorial elements of the two infantile books in order to highlight the points of convergence and divergence of the mythical elements existing in the infantile books compared with the epic of “The Odyssey”. The detection of common and distinct elements is undertaken through the localization and the comparison of the total narrative structure of the three texts and the content analysis of selected episodes that are included in the three books; The inference related to the adaptation of a myth into a reading text will also allow further investigation of the analysed topic in a wider sample of texts.

description: Objectives: Adequate nutrition is an important factor to determine the health and well- being of women, children and society as a whole. Although various nutritional policies were formulated and aimed at reducing malnutrition at the global level, the magnitude of malnutrition (body mass index [BMI] < 18.5 kg/m 2 ) among women remained between 10% and 40% in most low- and middle-income countries. We aimed to determine the preva- lence of malnutrition and to identify the associated risk factors among women of repro- ductive age. Study design: A cross-sectional study was conducted in Ziway Dugda district in Ethiopia among 430 women of reproductive age between September 20 and November 21, 2015. Methods: A systematic sampling method was used to select the study participants. Descriptive statistics and logistic regression were used to determine the prevalence of malnutrition and to identify associated independent risk factors such as women ' s age, housing conditions, drinking water sources, habits of hand washing, dietary intake and food insecurity. Results: The mean values of weight, height and BMI of the study participants were 51 kg, 157 cm and 18.1 kg/m 2 , respectively. Prevalence of malnutrition (BMI < 18.5 kg/m 2 ) among women of reproductive age was found to be 48.6%. Being in the age group of 26 e 35 years (adjusted odds ratio [AOR] ¼ 0.50, 95% confidence interval [CI] ¼ 0.26 e 0.84), thatched housing conditions (AOR ¼ 1.83, 95% CI ¼ 1.16 e 2.89), unprotected sources of drinking water (AOR ¼ 1.65, 95% CI ¼ 1.06 e 2.57), lack of habit of hand wash after using the toilet (AOR ¼ 1.62, 95% CI ¼ 1.06 e 2.47), consumption of fish (AOR ¼ 2.12, 95% CI ¼ 1.12 e 3.99), consumption of dairy products (AOR ¼ 2.40, 95% CI ¼ 1.42 e 4.03) and food insecurity (AOR ¼ 2.44, 95% CI ¼ 1.50 e 3.95) were considered as independent predictors of risk for having malnutrition among women of the same age group compared to women from food secured households.Conclusions: A high prevalence of malnutrition (48.6%) was observed among women of reproductive age. Although nutrient-rich foods were available, their consumption appears insufficient. Hence, it is strongly recommended to have behavioural change communica- tion for enhancing adequate intake of a diversified diet and to promote environmental and hygienic conditions of women through improving their socio-economic status

description: Introduction: Accelerated water quality change due to industrial pollution is one of the major environmental concerns throughout the world. In Ethiopia, Pollution of surface water is largely a problem due to rapid urbanization and industrialization. The main objective of this study was to determine the pollution profile of Modjo River throughout study sites. Methods: A cross-sectional study was conducted to assess water pollution along Modjo River. Ten sampling sites were selected based on wastewater discharge, accessibility and pollution feasibility of river water. The sampling frequency was for two rounds composite sample taken from Modjo River. The chemical parameters were determined in the laboratory by using standard instrumental method AAS and UV-VIS. Results: Temperature, Electrical conductivity, Turbidity and PH were within the acceptable limit of surface water standard. Ammonia Nitrogen (NH3-N), BOD, Phosphorous, Nitrate Nitrogen (NO3-N) was all above acceptable limit except for BOD and Ammonia Nitrogen in station 1 within acceptable limit. TDS above standard limit in Stations 5, 6, 7, 8, 10 were above acceptable limit. COD of station 2, 3, 4, 8, 9 and above the acceptable limit. For chromium stations 3, 6, 8, 9 and 10 above acceptable limit of surface water standards. Conclusion and recommendations: The study result found that there was change on the physico-chemical parameters from upstream to downstream areas, which indicates an introduction of pollution load from industrial wastewater. It is recommended that National Environmental Quality Standard (NEQS) should be strictly enforced on all industries to install facilities and treat wastewater effectively.

description: In 1993, Baxter gave $2^{m_Q}$ eigenvalues of the transfer matrix of the $N$-state superintegrable chiral Potts model with spin-translation quantum number $Q$, where $m_Q=\lfloor(NL-L-Q)/N\rfloor$. In our previous paper we studied the Q=0 ground state sector, when the size $L$ of the transfer matrix is chosen to be a multiple of $N$. It was shown that the corresponding $τ_2$ matrix has a degenerate eigenspace generated by the generators of $r=m_0$ simple $sl_2$ algebras. These results enable us to express the transfer matrix in the subspace in terms of these generators $E_m^{\pm}$ and $H_m$ for $m=1,...,r$. Moreover, the corresponding $2^r$ eigenvectors of the transfer matrix are expressed in terms of rotated eigenvectors of $H_m$.

description: The growth of 5G and edge computing has enabled the emergence of Internet of Vehicles. It supports different types of services with different resource and service requirements. However, limited resources at the edge, high mobility of vehicles, increasing demand, and dynamicity in service request-types have made service placement a challenging task. A typical static placement solution is not effective as it does not consider the traffic mobility and service dynamics. Handling dynamics in IoV for service placement is an important and challenging problem which is the primary focus of our work in this paper. We propose a Deep Reinforcement Learning-based Dynamic Service Placement (DRLD-SP) framework with the objective of minimizing the maximum edge resource usage and service delay while considering the vehicle's mobility, varying demand, and dynamics in the requests for different types of services. We use SUMO and MATLAB to carry out simulation experiments. The experimental results show that the proposed DRLD-SP approach is effective and outperforms other static and dynamic placement approaches.

description: Outflows driven by active galactic nuclei (AGN) are expected to have a significant impact on the host galaxy evolution, but it is still debated how they are accelerated and propagate on galaxy-wide scales. This work addresses these questions by studying the link between X-ray, nuclear ultra-fast outflows (UFOs) and extended ionised outflows, for the first time in two quasars close to the peak of AGN activity ($z\sim2$), where AGN feedback is expected to be more effective. As targets, we selected two multiple-lensed quasars at $z\sim1.5$, HS 0810+2554 and SDSS J1353+1138, known to host UFOs and observed with the near-IR integral field spectrometer SINFONI at the VLT. We performed a kinematical analysis of the [O III]$λ$5007 optical emission line, in order to trace the presence of ionised outflows. We detected spatially resolved ionised outflows in both galaxies, extended more than 8 kpc and moving up to $v>2000$ km/s. We derived mass outflow rates of $\sim$12 M$_{sun}$/yr and $\sim$2 M$_{sun}$/yr for HS 0810+2554 and SDSS J1353+1138. Comparing with the co-hosted UFO energetics, the ionised outflow energetics in HS 0810+2554 is broadly consistent with a momentum-driven regime of wind propagation, while in SDSS J1353+1138 it differs by a factor of $\sim$100 from theoretical predictions, requiring either a massive molecular outflow or a high variability of the AGN activity to account for such a discrepancy. By additionally considering our results with those from the small sample of well-studied objects (all local but one), with both UFO and extended (ionised/atomic/molecular) outflow detections, we found that in 10 out of 12 galaxies the large-scale outflow energetics is consistent with the theoretical predictions of either a momentum- or an energy-driven scenario. This suggests that such models explain relatively well the acceleration mechanism of AGN-driven winds on large scales.

description: In this article, we reevaluate supernovae (SN) constraints on the diffusion time of neutrinos for a family of extensions of the Standard Model that incorporate new light scalar and vector mediators. We compute the neutrino mean free path, taking into account medium effects in the neutrino-nucleon scattering cross-section, and a radial dependence of the density, energy, and temperature inside the proto-neutron star to determine the coupling strengths compatible with SN1987A constraints on the time duration signal of diffusing neutrinos. We show that medium effects can induce an order of magnitude enhancement in the neutrino mean free path with respect to the vacuum calculation. The increase is more significant when new physics terms dominate over the Standard Model contribution (that is, for small mediator mass and large couplings). Finally, we interpret these results as bounds on the parameter space of a vector $U(1)_{B-L}$ model and scalar lepton number conserving and lepton number violating scenarios, improving on previous results in the literature where medium effects were ignored. We show that SN constraints on the neutrino diffusion time lie within regions of the parameter space that are already ruled out by other experimental constraints. We also comment on potential limits due to changes in the SN equation of state or right-handed neutrino free-streaming, but argue that detailed numerical simulations are needed to improve the reliability of these limits.

Finite-time two-spin quantum Otto engines: shortcuts to adiabaticity vs. irreversibility

description: We propose a quantum Otto cycle in a two spin-$1/2$ anisotropic XY model in a transverse external magnetic field. We first characterize the parameter regime that the working medium operates as an engine in the adiabatic regime. Then, we consider finite-time behavior of the engine with and without utilizing a shortcut to adiabaticity (STA) technique. STA schemes guarantee that the dynamics of a system follows the adiabatic path, at the expense of introducing an external control. We compare the performance of the non-adiabatic and STA engines for a fixed adiabatic efficiency but different parameters of the working medium. We observe that, for certain parameter regimes, the irreversibility, as measured by the efficiency lags, due to finite-time driving is so low that non-adiabatic engine performs quite close to the adiabatic engine, leaving the STA engine only marginally better than the non-adiabatic one. This suggests that by designing the working medium Hamiltonian one may spare the difficulty of dealing with an external control protocol.

description: Graphene in the quantum Hall regime exhibits a multi-component structure due to the electronic spin and chirality degrees of freedom. While the applied field breaks the spin symmetry explicitly, we show that the fate of the chirality SU(2) symmetry is more involved: the leading symmetry-breaking terms differ in origin when the Hamiltonian is projected onto the central (n=0) rather than any of the other Landau levels. Our description at the lattice level leads to a Harper equation; in its continuum limit, the ratio of lattice constant a and magnetic length l_B assumes the role of a small control parameter in different guises. The leading symmetry-breaking terms are direct (n=0) and exchange (n different from 0) terms, which are algebraically small in a/l_B. We comment on the Haldane pseudopotentials for graphene, and evaluate the easy-plane anisotropy of the graphene ferromagnet.

description: Le conflit russo-ukrainien s'est enraciné sur des enjeux de mémoire. Cent ans de résistance à la domination russe ont construit une opposition entre deux peuples, deux cultures, deux langues et deux aspirations à des modèles sociétaux. La résolution d'un tel conflit nécessite une réflexion sur la diversité des mémoires, sur le rapport entre Mémoire et Histoire et sur l'apport de l'expérience historique dans la compréhension des tensions actuelles. Une réflexion aussi sur la nécessaire refondation des associations mémorielles.
