description: Google BigTable's scale-out design for distributed key-value storage inspired a generation of NoSQL databases. Recently the NewSQL paradigm emerged in response to analytic workloads that demand distributed computation local to data storage. Many such analytics take the form of graph algorithms, a trend that motivated the GraphBLAS initiative to standardize a set of matrix math kernels for building graph algorithms. In this article we show how it is possible to implement the GraphBLAS kernels in a BigTable database by presenting the design of Graphulo, a library for executing graph algorithms inside the Apache Accumulo database. We detail the Graphulo implementation of two graph algorithms and conduct experiments comparing their performance to two main-memory matrix math systems. Our results shed insight into the conditions that determine when executing a graph algorithm is faster inside a database versus an external system---in short, that memory requirements and relative I/O are critical factors.

description: Recent studies in magnetic nanolithography show that a variety of complex magnetic states emerge as a function of a single magnetic island's aspect ratio. We propose a model which, in addition to fitting experiments, predicts magnetic states with continuous symmetry at particular aspect ratios and reveals a duality between vortex and vertex states. Our model then opens new means of engineering novel types of artificial spin systems, and their application to complex magnetic textures in devices and computing.

description: We consider the problem of estimating unknown transmittance $θ$ of a target bathed in thermal background light. As quantum estimation theory yields the fundamental limits, we employ the lossy thermal-noise bosonic channel model, which describes sensor-target interaction quantum mechanically in many practical active-illumination systems (e.g., using emissions at optical, microwave, or radio frequencies). We prove that quantum illumination using two-mode squeezed vacuum (TMSV) states asymptotically achieves minimal quantum Cramér-Rao bound (CRB) over all quantum states (not necessarily Gaussian) in the limit of low transmitted power. We characterize the optimal receiver structure for TMSV input, and show its advantage over other receivers using both analysis and Monte Carlo simulation.

Assessment of Substance use and Risky Sexual Behaviour among Haramaya University Students
Creators: name: Derese, Andualem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Background: Substance use and problems arising from it are increasing all over the world, and currently together with HIV/AIDS epidemic, become one of the most threatening and challenging social and public health problems. University students are more vulnerable to wider sexual and reproductive health (SRH) and HIVAIDS problems due to new environment with poor protection, age and the need to explore life, peer pressure and absence of proactive programs. Objectives: This study assessed the prevalence of substance use and its association with risky sexual behaviour among Haramaya University students. Methods: A cross-sectional survey was carried out among 725 randomly selected Haramaya University undergraduate students from December 2010 to January 2011 using a self-administered questionnaire. Students are stratified first by campus and then by year of study. Sampling with probability proportional to size was used to select students from each year of study using students list as a sampling frame. Descriptive statistics was used to describe the study population and cross-tabulation was done to see the association between dependent and independent variables. Logistic regressions with 95% confidence intervals were calculated to determine independent predictors of risky sexual behaviour. Result: Among 725 participants, 390 (53.8%) reported having used at least one substance in their lifetime. The most commonly used substance was alcohol (41.7%), followed by khat (30.3%), cigarette (11.3%) and illicit drugs (3.9%). Of the total respondents, 243 (33.5%) had sexual experience in their lifetime. Among sexually active, 28(11.5%) had multiple sexual partners in the last three months and 29(16.3%) of males had sex with commercial sex workers. One hundred forty nine (61.6%) of sexually active students used condoms during the last sex but its consistent use was 55.7%. Use of khat, alcohol and cigarette was significantly and independently associated with risky sexual activities with AOR (95% CI) of 2.58 (1.58, 4.22), 2.46 (1.52, 3.98) and 2.22 (1.19, 4.14) respectively. Conclusion: The prevalence of substance use among Haramaya university students was high .Use of khat, alcohol and cigarette was significantly associated with risky sexual activities. Awareness raising about safer sex and consequences of substance together with taking the necessary disciplinary measure for those who break the rule and regulation set by the university is highly advisable. viii

description: We numerically compute the flow induced in a spherical shell by fixing the outer sphere and rotating the inner one. The aspect ratio $ε=(r_o-r_i)/r_i$ is set at 0.04 and 0.02, and in each case the Reynolds number measuring the inner sphere's rotation rate is increased to $\sim10\%$ beyond the first bifurcation from the basic state flow. For $ε=0.04$ the initial bifurcations are the same as in previous numerical work at $ε=0.154$, and result in steady one- and two-vortex states. Further bifurcations yield travelling wave solutions similar to previous analytic results valid in the $ε\to0$ limit. For $ε=0.02$ the steady one-vortex state no longer exists, and the first bifurcation is directly to these travelling wave solutions, consisting of pulse trains of Taylor vortices travelling toward the equator from both hemispheres, and annihilating there in distinct phase-slip events. We explore these time-dependent solutions in detail, and find that they can be both equatorially symmetric and asymmetric, as well as periodic or quasi-periodic in time.

description: Models based on nuclear energy density functionals can provide access to a multitude of observables for thousands of nuclei in a single framework with microscopic foundations. Such models can rival the accuracy of more phenomenological approaches, but doing so requires adjusting parameters to thousands of nuclear masses. To keep such large-scale fits feasible, several symmetry restrictions are generally imposed on the nuclear configurations. One such example is time-reversal invariance, which is generally enforced via the Equal Filling Approximation (EFA). Here we lift this assumption, enabling us to access the spin and current densities in the ground states of odd-mass and odd-odd nuclei and which contribute to the total energy of such nuclei through so-called "time-odd" terms. We present here the Skyrme-based BSkG2 model whose parameters were adjusted to essentially all known nuclear masses without relying on the EFA, refining our earlier work [G. Scamps et al., EPJA 57, 333 (2021), arXiv:2011.07904]. Moving beyond ground state properties, we also incorporated information on the fission barriers of actinide nuclei in the parameter adjustment. The resulting model achieves a root-mean-square (rms) deviation of (i) 0.678 MeV on 2457 known masses, (ii) 0.027 fm on 884 measured charge radii, (iii) 0.44 MeV and 0.47 MeV, respectively, on 45 reference values for primary and secondary fission barriers of actinide nuclei, and (iv) 0.49 MeV on 28 fission isomer excitation energies. We limit ourselves here to a description of the model and the study the impact of lifting the EFA on ground state properties such as binding energies, deformation and pairing, deferring a detailed discussion of fission to a forthcoming paper.

description: Resonance fluorescence from atomic systems consists of a single spectral peak that evolves into a Mollow triplet for a strong excitation field. Photons from different peaks of the triplet show distinct photon correlation that make the fluorescence a useful light source for quantum information purpose. We characterize the fluorescence of a single optically trapped $^{87}$Rb atom that is excited resonantly at different power levels. Second-order correlation measurements reveal the single photon nature of the fluorescence concurrently with Rabi oscillations of a strongly excited atom. The asymmetry in correlations between photons from two sidebands of the fluorescence spectrum when the atom is exposed to an off-resonant field further indicates that there is a preferred time-ordering of the emitted photons from different sidebands.

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

description: Background: Malnutrition is common in hospital and occurs in more than 50% of hospitalized patients. It is one of the most important factors which determine the clinical outcomes of patients. Therefore, most of the developed countries has made tremendous progress in screening for malnutrition at admission and giving nutritional support for those that required. The burden of malnutrition hardly ravages in developing countries especially in Africa and talking about it tend to refer only to children forgetting adults. Thereby, medical awareness is insufficient and in Ethiopia as well as in several countries, screening hospitalized patients for malnutrition is not a routine part of treatment. If so, some hospitals still used certain common anthropometric and biological markers. First step of treating is screening and screened required a validated screening tool which has not been properly addressed. Objective: To validate subjective global assessment (SGA) against full nutritional assessment (FNA) and to assess its reliability among adult surgical patients for effective integration in daily surgical wards practice in Black Lion Specialized Hospital. Methods: The study design was a facility based, cross-sectional concurrent validation design. The study was conducted at Black Lion Specialized Hospital in surgical department. Data were collected from February-April 2018 and one hundred hospitalized patients aged ≥18 years were screened randomly using systematic sampling. Concurrent validity was assessed through sensitivity, specificity, positive predictive value and negative predictive value of the SGA comparing to FNA considered as gold standard. Its reliability assessed by cronbach's alpha. SPSS version 21 was used for analysis. Results: A total of 100 patients aged ≥18 years participated in this study and fifty two percent (52%) were male. Among all abdominal operations performed, fifty nine of the patients (59%) were diagnosed for gastrointestinal cancer and 41 patients (41%) with benign or acute GI disease. Considering FNA as the gold standard, the sensitivity and specificity of SGA were 98.3% and 73.2% respectively. The internal consistency of SGA questionnaire measured using Cronbach's α coefficient gave a value of α =0.805. Conclusion and Recommendation: In this study, SGA showed a high level of sensitivity with a specificity >70%. The reliability of the SGA questionnaire is acceptable and showed an agreement with FNA. Therefore SGA is applicable in Ethiopian settings. However, to overcome self-weight report issue, further research on modification of the SGA regarding weight change item might be needed for cultural adaptation.

description: With Gaussian expansion method (GEM), realistic wave functions are used to calculate coupled-channel effects for the bottomonium under the framework of ${}^3P_0$ model. The simplicity and accuracy of GEM are explained. We calculate the mass shifts, probabilities of the $B$ meson continuum, $S-D$ mixing angles, strong and dielectric decay widths. Our calculation shows that both $S-D$ mixing and the $B$ meson continuum can contribute to the suppression of the vector meson's dielectric decay width. We suggest more precise measurements on the radiative decays of $Υ(10580)$ and $Υ(11020)$ to distinguish these two effects. The above quantities are also calculated with simple harmonic oscillator (SHO) wave function approximation for comparison. The deviation between GEM and SHO indicates that it is essential to treat the wave functions accurately for near threshold states.

description: Over the past decade, Boozer has argued that three-dimensional (3D) magnetic reconnection fundamentally differs from two-dimensional (2D) reconnection due to the fact that the separation between any pair of neighboring field lines almost always increases exponentially over distance in a 3D magnetic field. According to Boozer, this feature makes 3D field-line mapping chaotic and exponentially sensitive to small non-ideal effects; consequently, 3D reconnection can occur without intense current sheets. We test Boozer's theory via ideal and resistive reduced magnetohydrodynamic simulations of the Boozer-Elder coronal loop model driven by sub-Alfvenic footpoint motions [A. H. Boozer and T. Elder, Physics of Plasmas 28, 062303 (2021)]. Our simulation results significantly differ from their predictions. The ideal simulation shows that Boozer and Elder under-predict the intensity of current density due to missing terms in their reduced model equations. Furthermore, resistive simulations of varying Lundquist numbers show that the maximal current density scales linearly rather than logarithmically with the Lundquist number.

description: A number of recent observational studies of Galactic globular clusters have measured the variation in the slope of a cluster's stellar mass function $α$ with clustercentric distance $r$. In order to gather a deeper understanding of the information contained in such observations, we have explored the evolution of $α(r)$ for star clusters with a variety of initial conditions using a large suite of $N$-body simulations. We have specifically studied how the time evolution of $α(r)$ is affected by initial size, mass, binary fraction, primordial mass segregation, black hole retention, an external tidal field, and the initial mass function itself. Previous studies have shown that the evolution of $α_G$ is closely related to the amount of mass loss suffered by a cluster. Hence for each simulation we have also followed the evolution of the slope of the cluster's global stellar mass function, $α_G$, and have shown that clusters follow a well-defined track in the $α_G$-$dα(r)/d(ln(r/r_m))$ plane. The location of a cluster on the $α_G-dα(r)/d(ln(r/r_m))$ plane can therefore constrain its dynamical history and, in particular, constrain possible variations in the stellar initial mass function. The $α_G$-$dα(r)/d(ln(r/r_m))$ plane thus serves as a key tool for fully exploiting the information contained in wide field studies of cluster stellar mass functions.

description: Introduction:Primary dysmenorrhea, or painful menstruation in the absence of pelvic pathology is the most common gynecological compliant among adolescence and young women. Its adverse consequence ranges from short term school absenteeism to family and personal disruption.Local studies especially among younger adolescent students exploring primary dysmenorrhea and its consequences on school attendance isscares. There for, this study aimed to assess the prevalence of primary dysmenorrheal and itsconsequences on school attendance. Method: A Cross-sectional study was conducted from March,7 to 21,2019 amongpublic secondary school students in Waliso town. Stratified random sampling technique was used to enroll 340 participants. Data were collected using pretested self-administered questionnaire. Data was cleaned, coded and entered into Epi info 7 and exported to SPSS version 25 for analysis. Bivariate and multivariable logistic regression model was applied to determine factors associated with primary dysmenorrhea.Pearson's Chi-square test was used to determine the relationship between primary dysmenorrhea and school absenteeism. Results: Primary dysmenorrhea was reported by 247 (75.1%) of the participant. It was mild in 108(43.7%), moderate in 98(39.7%), and severe in 41(16.6%) of the respondents. It was accompanied by other symptoms like back pain 184 (55.9%), fatigue 159 (43.3%) and headache 63(19. 1%).Out of dysmenorric students 96(38.9%) of them reported consequent absence from school.Pearson Chi-square test showed statistically significant association between severity of primary dysmenorrheaand school activities. This was explained by school absence ( X 2 df=2=17.9, p<0.001), loss of concentration ( X IX 2 df=2=14.5, p<0.001), lack of focus on exam (X 2 df=2=11.4, p<0.001) and restriction of physical education. Primary dysmenorrhea was found to have relatively strong association with irregular menstrual cycle, shorter length of menstrual cycle and longer menstrual flow days. Only 7(2.8%)of the participants seek medical care. Conclusion and recommendation: Primary dysmenorrhea was found to becommon problem among female adolescent students and had consequences on student school attendance and limited their daily school activities.Comprehensive school education program on menarche and menstrual problems may help girls to cope better with dysmenorrhea and appropriately seek medical assistance.

description: We study dual conformal transformations of minimal area surfaces in $AdS_5 \times S^5$ corresponding to holographic smooth Wilson loops and some other related observables. To act with dual conformal transformations we map the string solutions to the dual space by means of T-duality, then we apply a conformal transformation and finally T-dualize back to the original space. The transformation maps between string solutions with different boundary contours. The boundary contours of the minimal surfaces are not mapped back to the AdS boundary, and the regularized area of the surface changes.

description: This paper deals with the alternative mathematical modeling of the two-side platform. Two-sided platforms are specific multi-sided platforms that bring together two distinct groups of a model. The stochastic modeling by adapting various innovative mathematical methods including the first exceed theory and the stochastic pseudo-game theory has been applied for describing a two-sided platform more properly. A stochastic pseudo-game model is newly introduced to solve the two-sided platform more effectively. Analytically tractable results for operation thresholds for maximizing profits are provided and it also delivers the optimal balance of a two-sided platform. The paper includes how these innovative models are applied into various two-sided market situations. Additionally, users could conduct these multi-sided models to real business developments and the case practices of these unique models shall help the readers who want to find recommendations of their business situations easily even without having any mathematical background.

description: In this paper we study the direct production of the diphoton resonance $X$ which has been suggested by 2015 data at the LHC, in $e^+e^-\to Xγ/XZ$ processes at the ILC. We derive an analytic expression for the scattering amplitudes of these processes, and present a comprehensive analysis for determining the properties of $X$ at the ILC. A realistic simulation study for $e^+e^-\to Xγ$ is performed based on the full detector simulation to demonstrate the capabilities of the ILC experiment. Complementary to the searches at the LHC, prospects of the measurement of the absolute values of production cross-section are obtained for the ILC using recoil technique without assuming decay modes of $X$. In addition, we have studied the searches for $X\to\rm{invisible}$ and $X\to b\bar{b}$ modes, which are challenging at the LHC, and found that these decay modes can be discovered with high significance if their branching ratios are large enough.

description: The dielectric response of non-interacting dipoles is discussed in the framework of the classical model of stochastic reorientations in an asymmetric double well potential (ADWP). In the nonlinear regime, this model exhibits some pecularities in the static response. We find that the saturation behavior of the symmetric double well potential model does not follow the Langevin function and only in the linear regime the standard results are recovered. If a finite asymmetry is assumed, the nonlinear susceptibilities are found to change the sign at a number of characteristic temperatures that depend on the magnitude of the asymmetry, as has been observed earlier for the third-order and the fifth-order response. If the kinetics of the barrier crossing in the ADWP model is described as a two-state model, we can give analytical expressions for the values of the characteristic temperatures. The results for the response obtained from a (numerical) solution of the Fokker-Planck equation for the Brownian motion in a model ADWP behaves very similar to the two-state model for high barriers. For small barriers no clearcut time scale separation between the barrier crossing process and the intra-well relaxation exists and the model exhibits a number of time scales. In this case, the frequency-dependent linear susceptibility at low temperatures is dominated by the fast intra-well transitions and at higher temperatures by the barrier crossing kinetics. We find that for nonlinear susceptibilities the latter process appears to be more important and the intra-well transitions play only role at the lowest temperatures.

description: Current theories of language recovery after stroke are limited by a reliance on small studies. Here, we aimed to test predictions of current theory and resolve inconsistencies regarding right hemispheric contributions to long-term recovery. We first defined the canonical semantic network in 43 healthy controls. Then, in a group of 43 patients with chronic post-stroke aphasia, we tested whether activity in this network predicted performance on measures of semantic comprehension, naming, and fluency while controlling for lesion volume effects. Canonical network activation accounted for 22-33% of the variance in language test scores. Whole-brain analyses corroborated these findings, and revealed a core set of regions showing positive relationships to all language measures. We next evaluated the relationship between activation magnitudes in left and right hemispheric portions of the network, and how right hemispheric activation related to the extent of left hemispheric damage. Activation magnitudes in the each hemispheric network were strongly correlated, but four right frontal regions showed heightened activity in patients with large lesions. Activity in two of these regions (inferior frontal gyrus pars opercularis and supplementary motor area) was associated with better language abilities in patients with larger lesions, but poorer language abilities in patients with smaller lesions. Our results indicate that bilateral language networks support language processing after stroke, and that right hemispheric activations related to extensive left hemisphere damage occur outside of the canonical semantic network and differentially contribute to in their relationship to behavior depending on the extent of left hemispheric damage

description: Heartbeat stars (HB stars) are a class of eccentric binary stars with close periastron passages. The characteristic photometric HB signal evident in their light curves is produced by a combination of tidal distortion, heating, and Doppler boosting near orbital periastron. Many HB stars continue to oscillate after periastron and along the entire orbit, indicative of the tidal excitation of oscillation modes within one or both stars. These systems are among the most eccentric binaries known, and they constitute astrophysical laboratories for the study of tidal effects. We have undertaken a radial velocity (RV) monitoring campaign of Kepler HB stars in order to measure their orbits. We present our first results here, including a sample of 21 Kepler HB systems, where for 19 of them we obtained the Keplerian orbit and for 3 other systems we did not detect a statistically significant RV variability. Results presented here are based on 218 spectra obtained with the Keck/HIRES spectrograph during the 2015 Kepler observing season, and they have allowed us to obtain the largest sample of HB stars with orbits measured using a single instrument, which roughly doubles the number of HB stars with an RV measured orbit. The 19 systems measured here have orbital periods from 7 to 90 d and eccentricities from 0.2 to 0.9. We show that HB stars draw the upper envelope of the eccentricity - period distribution. Therefore, HB stars likely represent a population of stars currently undergoing high eccentricity migration via tidal orbital circularization, and they will allow for new tests of high eccentricity migration theories.

description: Precise and efficient control of quantum systems is essential to perform quantum information processing tasks. In terms of adiabatic speedup via leakage elimination operator approach, for a closed system, the ideal pulse control conditions have been theoretically derived by P-Q partitioning technique. However, it is a challenge to design the corresponding control pulses for an open system, which requires to tackle noisy environments. In this paper, we apply the stochastic search procedures to an open qutrit system and successfully obtain the optimal control pulses for significant adiabatic speedup. The calculation results show that these optimal pulses allow us to acquire higher fidelities than the ideal pulses. The improvement of fidelity is large for relatively strong system-bath coupling strength and high bath temperature. For certain coupling strength and bath temperature, the maximal improvement can be achieved for a critical characteristic frequency which represents the memory time of the environment. Our investigation indicates that the stochastic search procedures are powerful tools to design control pulses for combating the detrimental effects of the environment.

description: The double copy relates momentum-space scattering amplitudes in gauge and gravity theories. It has also been extended to classical solutions, where in some cases an exact double copy can be formulated directly in terms of products of fields in position space. This is seemingly at odds with the momentum-space origins of the double copy, and the question of why exact double copies are possible in position space and when this form will break has remained largely unanswered. In this paper, we provide an answer to this question, using a recently developed twistorial formulation of the double copy. We show that for certain vacuum type-D solutions, the momentum-space, twistor-space and position-space double copies amount to the same thing, and are directly related by integral transforms. Locality in position space is ultimately a consequence of the very special form of momentum-space three-point amplitudes, and we thus confirm suspicions that local position-space double copies are possible only for highly algebraically-special spacetimes.

description: A comparative cross sectional study was carried out in February 2002 among women of reproductive age group in rural South Gondar zone to assess the factors affecting the success and sustainability of a Community based reproductive health program. The study was conducted in eight peasant associations of the zone taking successful and weak/failed program areas for comparison of various characteristics. Both quantitative and qualitative methods were used for data collection. The qualitative method included key informants interview, and Focus Group Discussions with functional and non-functional (drop out) Community-based reproductive health agents (CBRHAs). A multistage sampling technique was employed to select 792 study subjects for the quantitative part. The results indicated that about 92% of respondents know at least one Modern Contraceptive Methods (MCM) in successful as compared to 83% in weak program areas. The difference was statistically significant [OR(95% CI) = 2.35 (1.47, 3.8)]. The proportions of women who were using MCM (14.65% & 4.55%) & attended antenatal care service at least once (17.4% & 10.8% ) were found to be significantly higher in Successful than weak program areas respectively [OR(95%CI) = 1.74(1.10,2.76) respectively]. Large proportions of the respondents (94%) are aware of HIV/AIDS but detail knowledge of transmission routes (mean score = 1.2/4) and prevention methods (1.9/4) were found to be low. Awareness to the presence of the CBRHA in the locality (61.1% & 40.4%), Participation in selection of the agent (4.8% & 1.5%), Acceptance of the agent (90.4% & 59.4%), ever talk to CBRHA about Family Planning or reproductive health (29.8% & 7.8%), Knowledge of a functional village health committee (56.8% & 21.2%) in the locality were significantly higher in successful than in weak program areas respectively. [OR(95%CI) = 2.32(1.74,3.08), 3.28(1.22,9.27), 6.65(3.59,12.43), 5.05(3.22,7.96), and 5.66(3.97,8.09) respectively] On multivariate analysis acceptance of the CBRHAs, level of willingness to work as CBRHA, and satisfaction by the CBRH service were significantly associated with CBRH service use [OR(95%CI) = 1.62 (1.75,3.48), 2.79(1.66,4.67), and 3.4(1.71,6.73) respectively] viii In general, community involvement in selection of the volunteers, acceptance of the CBRHAs, interpesonal communication by the agents, satisfaction by the service and level of support to the agents are found to be the major factors affecting the CBRHP. Therefore, program managers and coordinators are advised to improve the level of community participation & the overall support provided to the program in order to enhance the success & sustained delivery of quality & integrated reproductive health services to the community.

description: We consider limits on the local ($z=0$) density ($n_0$) of extragalactic neutrino sources set by the nondetection of steady high-energy neutrino sources producing $\gtrsim50$ TeV muon multiplets in the present IceCube data, taking into account the redshift evolution, luminosity function and neutrino spectrum of the sources. We show that the lower limit depends moderately on source spectra and strongly on redshift evolution. We find $n_0\gtrsim{10}^{-8}-{10}^{-7}~{\rm Mpc}^{-3}$ for standard candle sources evolving rapidly, $n_s\propto{(1+z)}^3$, and $n_0\gtrsim{10}^{-6}-{10}^{-5}~{\rm Mpc}^{-3}$ for nonevolving sources. The corresponding upper limits on their neutrino luminosity are $L_{ν_μ}^{\rm eff}\lesssim10^{42}-10^{43}~{\rm erg}~{\rm s}^{-1}$ and $L_{ν_μ}^{\rm eff}\lesssim10^{41}-10^{42}~{\rm erg}~{\rm s}^{-1}$, respectively. Applying these results to a wide range of classes of potential sources, we show that powerful blazar jets associated with active galactic nuclei are unlikely to be the dominant sources. For almost all other steady candidate source classes (including starbursts, radio galaxies, and galaxy clusters and groups), an order of magnitude increase in the detector sensitivity at $\sim0.1-1$ PeV will enable a detection (as point sources) of the few brightest objects. Such an increase, which may be provided by next-generation detectors like IceCube-Gen2 and an upgraded KM3NET, can improve the limit on $n_0$ by more than two orders of magnitude. Future gamma-ray observations (by Fermi, HAWC and CTA) will play a key role in confirming the association of the neutrinos with their sources.

Thermoelectric Transport in Holographic Quantum Matter under Shear Strain

description: We study the thermoelectric transport under shear strain in two spatial dimensional quantum matter using the holographic duality. General analytic formulae for the DC thermoelectric conductivities subjected to finite shear strain are obtained in terms of the black hole horizon data. Off-diagonal terms in the conductivity matrix appear also at zero magnetic field, resembling an emergent electronic nematicity which cannot nevertheless be identified with the presence of an anomalous Hall effect. For an explicit model study, we numerically construct a family of strained black holes and obtain the corresponding nonlinear stress-strain curves. We then compute all electric, thermoelectric, and thermal conductivities and discuss the effects of strain. While the shear elastic deformation does not affect the temperature dependence of thermoelectric and thermal conductivities quantitatively, it can strongly change the behavior of the electric conductivity. For both shear hardening and softening cases, we find a clear metal-insulator transition driven by the shear deformation. Moreover, the violation of the previously conjectured thermal conductivity bound is observed for large shear deformation.

description: Generators of the Poincaré group, for a free massive scalar field, are usually expressed in the momentum space. In this work we perform a transformation of these generators into the coordinate space. This (spatial)-position space is spanned by eigenvectors of the Newton-Wigner-Pryce operator. The motivation is a deeper understanding of the commutative spatial coordinate space in QFT, in order to investigate the non-commutative version thereof.
