description: We investigate various properties of extremal dyonic static black holes in Einstein-Maxwell-Dilaton theory. Using the fact that the long-range force between two identical extremal black holes always vanishes, we obtain a simple first-order ordinary differential equation for the black hole mass in terms of its electric and magnetic charges. Although this equation appears not to be solvable explicitly for general values of the strength a of the dilatonic coupling to the Maxwell field, it nevertheless provides a powerful way of characterising the black hole mass and the scalar charge. We make use of these expressions to derive general results about the long-range force between two non-identical extremal black holes. In particular, we argue that the force is repulsive whenever a>1 and attractive whenever a<1 (it vanishes in the intermediate BPS case a=1). The sign of the force is also correlated with the sign of the binding energy between extremal black holes, as well as with the convexity or concavity of the surface characterizing the extremal mass as a function of the charges. Our work is motivated in part by the Repulsive Force Conjecture and the question of whether long range forces between non-identical states can shed new light on the Swampland.

Creators: name: Bekele, Tolesa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: Background: Sexual coercion refers to a range of experiences that compel a person to have sex against her or his will, and it is a public health problem of concern throughout the world. This is not only because of physical injury that may result but also because of potentially harmful health behaviours that may be triggered in response to violence. The severity of the problem and inadequacy of the studies in this area has prompted the undertaking of this study. Objective: The aim of this study was to determine the magnitude and factors associated with sexual coercion among female students of Ambo University in 2012. Methods: A cross-sectional institution based study was conducted among female students of Ambo University from January, 2012 using the World Health Organization (WHO) multicountry self-administered standard questionnaire with minor modifications. Then 597 study participants were selected by simple random sampling method from selected departments using students' registration number. Data were entered using EpiData version 3.1 and analyzed using SPSS version16.0 statistical software packages. Thematic analysis was used for focus group discussions (FGDs). Results: About 77 (13%) of the female students were raped at least once in lifetime and 177 (30%) experienced an attempted rape in their lifetime. Most of the study participants 465 (78.8%) reported that they experienced sexual harassment in their lifetime. Among the victims of completed lifetime rape, 43 (55.4%) encountered unusual vaginal discharge, 29 (37.7%) had experienced unwanted pregnancy, 26 (33.8%) had abortion, 18 (23.4%) reported injury around the genitalia and 17 (22.1%) experienced swelling around the genitalia. Psychological outcomes like unhappiness, thinking that worthless person, suicidal ideation and suicidal attempt were reported by 70.1%, 64.9%, 22.1% and 2.6% of the rape victims, respectively. The odds of experiencing lifetime rape was higher among participants of 3rd year or more (AOR=2.97, 95%CI: 1.02, 8.62), 4th year (AOR=4.85, 95%, 1.38, 16.99), aged 24 years or more (AOR=3.92, 95%CI: 1.13, 13.55), female students who reported drinking alcohol (AOR=1.53, 95%CI: 1.63, 6.50), who had boyfriends (AOR=2.35, 95%CI: 1.71, 4.90), who had more than one sexual partner (AOR=2.64,955CI: 1.03, 6.77) and participants with history of divorced families (AOR=6.53, 95%CI: 1.38, 30.80). Conclusion: This study shows that sexual coercion is common and serious problem among university female students in the study area. Therefore, it is recommended that sexual coercion needs due attention and remedial action by policy makers, university officials, parents, students, non-governmental organizations and other concerned bodies to promote a harassment free educational environment for female students.

description: The spatiotemporal nature of neuronal behavior in spiking neural networks (SNNs) make SNNs promising for edge applications that require high energy efficiency. To realize SNNs in hardware, spintronic neuron implementations can bring advantages of scalability and energy efficiency. Domain wall (DW) based magnetic tunnel junction (MTJ) devices are well suited for probabilistic neural networks given their intrinsic integrate-and-fire behavior with tunable stochasticity. Here, we present a scaled DW-MTJ neuron with voltage-dependent firing probability. The measured behavior was used to simulate a SNN that attains accuracy during learning compared to an equivalent, but more complicated, multi-weight (MW) DW-MTJ device. The validation accuracy during training was also shown to be comparable to an ideal leaky integrate and fire (LIF) device. However, during inference, the binary DW-MTJ neuron outperformed the other devices after gaussian noise was introduced to the Fashion-MNIST classification task. This work shows that DW-MTJ devices can be used to construct noise-resilient networks suitable for neuromorphic computing on the edge.

description: Topological mosaic pattern (TMP) can be formed in two-dimensional (2D) moiré superlattices, a set of periodic and spatially separated domains with distinct topologies give rise to periodic edge states on the domain walls. In this study, we demonstrate that these periodic edge states play a crucial role in determining global topological properties. By developing a continuum model for periodic edge states with C6z and C3z rotational symmetry, we predict that a global topological phase transition at the charge neutrality point (CNP) can be driven by the size of domain walls and moiré periodicity. The Wannier representation analysis reveals that these periodic edge states are fundamentally chiral px +- ipy orbitals. The interplay between on-site chiral orbital rotation and neighboring hopping among chiral orbitals leads to band inversion and a topological phase transition. Our work establishes a general model for tuning local and global topological phases, paving the way for future research on strongly correlated topological flat minibands within topological mosaic patterns

description: Q-lumps are spinning planar topological solitons with stationary solutions that satisfy first-order Bogomolny equations. Q-lump scattering has previously been studied only in the charge two sector, by approximating time evolution by motion in the moduli space of stationary solutions. In this paper, higher charge scattering is studied via motion on families of 4-dimensional submanifolds of moduli space, obtained by imposing cyclic symmetries. The results are shown to be in good agreement with field theory simulations, which are then applied to study more complicated Q-lump scattering processes, including examples where the moduli space approximation is not applicable. A variety of exotic scattering events are presented.

description: We revisit the Affleck-Dine leptogenesis via the $L H_u$ flat direction with a light slepton field. Although the light slepton field is favored in low-energy SUSY phenomenologies, such as the muon $g-2$ anomaly and bino-slepton coannihilation, it may cause a problem in the Affleck-Dine leptogenesis: it may create an unwanted charge-breaking vacuum in the Affleck-Dine field potential so that the Affleck-Dine field is trapped during the course of leptogenesis. We investigate the conditions under which such an unwanted vacuum exists and clarify that both thermal and quantum corrections are important for the (temporal) disappearance of the charge-breaking minimum. We also confirm that if the charge-breaking vacuum disappears due to the thermal or quantum correction, the correct baryon asymmetry can be produced while avoiding the cosmological gravitino problem.

description: Insulator-based dielectrophoresis (iDEP) is a powerful particle analysis technique based on electric field scattering at material boundaries which can be used, for example, for particle filtration or to achieve chromatographic separation. Typical devices consist of microchannels containing an array of posts but large scale application was also successfully tested. Distribution and magnitude of the generated field gradients and thus the possibility to trap particles depends apart from the applied field strength on the material combination between post and surrounding medium and on the boundary shape. In this study we simulate trajectories of singe particles under the influence of positive DEP that are flowing past one single post due to an external fluid flow. We analyze the influence of key parameters (excitatory field strength, fluid flow velocity, particle size, distance from the post, post size, and cross-sectional geometry) on two benchmark criteria, i.e., a critical initial distance from the post so that trapping still occurs (at fixed particle size) and a critical minimum particle size necessary for trapping (at fixed initial distance). Our approach is fundamental and not based on finding an optimal geometry of insulating structures but rather aims to understand the underlying phenomena of particle trapping. A sensitivity analysis reveals that electric field strength and particle size have the same impact, as have fluid flow velocity and post dimension. Compared to these parameters the geometry of the post's cross-section (i.e. rhomboidal or elliptical with varying width-to-height or aspect ratio) has a rather small influence but can be used to optimize the trapping efficiency at a specific distance. We hence found an ideal aspect ratio for trapping for each base geometry and initial distance to the tip which is independent of the other parameters. As a result we present design criteria which we believe to be a valuable addition to the existing literature.

description: Purpose: Inspired by the American Society of Clinical Oncology's recommendations to strengthen the evidence base for older adults with cancer, the purpose of this systematic review is to identify the reporting of treatment efficacy and adverse events specific to older adults with cancer in Phase III chemo-therapeutic clinical trials. This review also investigates the frequency with which these data points were reported in the literature to identify gaps in reporting and opportunities to expand the knowledge base on clinical outcomes for older adults with cancer. Methods: Chemo-therapeutic clinical trial data published from July 1, 2016 to June 30, 2017 was reviewed. Manuscripts (n = 929) were identified based on keyword searches of EMBASE and PubMed. After removal of duplicates (n = 116) and articles that did not meet this study's inclusion criteria (n = 654), 159 articles were identified for review. Results: Reviewed papers were published in 36 different scientific journals and included twenty-five different cancer types. Of the 159 articles, 117 (73.6%) reported age-specific medians and 75 (47.2%) included stratifications of data by age. Treatment efficacy was reported in 96.2% of the articles with 39.9% reporting effectiveness of treatment by age. Reporting of adverse events was included in 84.9% of the articles with only 8.9% reporting these events stratified by age. Conclusion: Results suggest inadequate reporting of treatment efficacy and adverse events as well as basic descriptive statistics about the age distribution of study subjects. Conscious efforts are needed to address these deficiencies at every level of planning and conducting clinical trials as wells as reporting outcomes stratified by age. Ultimately, standardized reporting could lead to improved treatment decisions and outcomes for older adults with cancer.

description: A hybrid numerical model previously developed for combustion simulations is extended in this article to describe flame propagation and stabilization in porous media. The model, with a special focus on flame/wall interaction processes, is validated via corresponding benchmarks involving flame propagation in channels with both adiabatic and constant-temperature walls. Simulations with different channel widths show that the model can correctly capture the changes in flame shape and propagation speed as well as the dead zone and quenching limit, as found in channels with cold walls. The model is further assessed considering a pseudo 2-D porous burner involving an array of cylindrical obstacles at constant temperature, investigated in a companion experimental study. Furthermore, the model is used to simulate pore-scale flame dynamics in a randomly-generated 3-D porous media. Results are promising, opening the door for future simulations of flame propagation in realistic porous media.
Structural origins of the boson peak in metals: From high-entropy alloys to metallic glasses

description: The boson peak appears in all amorphous solids and is an excess of vibrational states at low frequencies compared to the phonon spectrum of the corresponding crystal. Until recently, the consensus was that it originated from "defects" in the glass. The nature of these defects is still under discussion, but the picture of regions with locally disturbed short-range order and/or decreased elastic constants has gained some traction. Recently, a different theory was proposed: The boson peak was attributed to the first van Hove singularity of crystal lattices which is only smeared out by the disorder. This new viewpoint assumes that the van Hove singularity is simply shifted by the decreased density of the amorphous state and is therefore not a glass-specific anomaly. In order to resolve this issue, we use computer models of a four-component alloy, alternatively with chemical disorder (high-entropy alloy), structural disorder, and reduced density. Comparison to a reference glass of the same composition reveals that the boson peak consists of additional vibrational modes which can be induced solely by structural disorder. While chemical disorder introduces fluctuations of the elastic constants, we find that those do not lead to sufficient local softening to induce these modes. A boson peak due to a reduction of density could be excluded for the present metallic system.

description: One-dimensional all-bands-flat lattices are networks with all bands being flat and highly degenerate. They can always be diagonalized by a finite sequence of local unitary transformations parameterized by a set of angles \(θ_{i}\). In our previous work, Ref.~\onlinecite{lee2023critical}, we demonstrated that quasiperiodic perturbations of the one-dimensional all-bands-flat lattice with \(θ_{i} = π/4\) give rise to a critical-to-insulator transition and fractality edges separating critical from localized states. In this study we consider the full range of angles \(θ_{i}\)s available for the all-bands-flat model and study the effect of the quasiperiodic perturbation. For weak perturbation, we derive an effective Hamiltonian and we identify the sets of \(θ_{i}\)s for which the effective model maps to extended or off-diagonal Harper models and hosts critical states. For all the other values of the angles the spectrum is localized. Upon increasing the perturbation strength, the extended Harper model evolves into the system with energy dependent critical-to-insulator transitions, that we dub \emph{fractality edges}. The case where the effective model maps onto the off-diagonal Harper model features a critical-to-insulator transition at a finite disorder strength.

description: BACKGROUND The major health problem of the country, Ethiopia has been largely preventable communicable diseases and nutritional disorders. Breast and cervical cancer is the primary non infectious disease following hypertension and diabetes. Breast and cervical cancers are public health problem and the most common cause of cancer deaths among women in developed or developing countries. However there is no adequate information regarding magnitude and associated risk factors of breast and cervical cancer in Ethiopia. This study identifies the magnitude and associated risk factors of breast and cervical cancer and some useful input for National Health Care Service. General Objective To assess the magnitude of breast and cervical cancer and associated risk factors for breast cancer in Addis Ababa, Tikur Anbessa Specialized referral hospital from March1/2013-april 15/2013. Methodology Cross-sectional study of retrospective secondary data and case control study were conducted in Addis Ababa, Tikur Anbessa Specialized referral Hospital. Result Breast and cervical cancers cross-sectional retrospective data were 753 and case control directly collected from cancer radiotherapy department and Gyn/Obs department were 357 included in the study. The mean age for breast cancer was 47.6 years with Sd 14.1, minimum age 15 years and maximum was 99 years and cervical cancer mean age 51.6 years with Sd 12.8 minimum age 20 and maximum 92 years. The incidence rate of breast cancer was 28.4 from 100,000 female and 15.7 from 100,000 female for cervical cancer. The breast cancer incidence was very high among A.A city dwellers. The body mass index of participants above 25.1kg/m2 4.6 times (AOR= 4.643 (95% Cl: 1.819, 12.896) more likely affected than body mass index less 25.1kg/m2.Age 50 years and above 6 time (AOR=6.003 (95% CI: 2.606, 13.830) more likely affected than lower age groups. Conclusion Incidence of breast cancer in Addis Ababa city was higher, which is needed more health check up and intervention. Ministry of health should have set clinical and self breast examination and cervical screening every six month for all age above 40 yrs, BMI greater than 25.1kg/m2 and those live in rented house.

description: We report the detection of a GeV $γ$-ray source which is spatially overlapping and thus very likely associated with the unidentified very-high-energy (VHE) $γ$-ray source HESS J1427-608 with the Pass 8 data recorded by the Fermi Large Area Telescope. The photon spectrum of this source is best described by a power-law with an index of $1.85\pm0.17$ in the energy range of $3-500$ GeV, and the measured flux connects smoothly with that of HESS J1427-608 at a few hundred GeV. This source shows no significant extension and time variation. The broadband GeV-TeV emission over four decades of energies can be well fitted by a single power-law function with an index of 2.0, without obvious indication of spectral cutoff toward high energies. Such a result implies that HESS J1427-608 may be a PeV particle accelerator. We discuss possible nature of HESS J1427-608 according to the multi-wavelength spectral fittings. Given the relatively large errors, either a leptonic or a hadronic model can explain the multi-wavelength data from radio to VHE $γ$-rays. The inferred magnetic field strength is a few $μ$G, which is smaller than typical values of supernova remnants (SNRs), and is consistent with some pulsar wind nebulae (PWNe). On the other hand, the flat $γ$-ray spectrum is slightly different from typical PWNe but similar to that of some known SNRs.

Modular flavour symmetry and orbifolds

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

description: We develop a bottom-up approach to flavour models which combine modular symmetry with orbifold constructions. We first consider a 6d orbifold $\mathbb{T}^2/\mathbb{Z}_N$, with a single torus defined by one complex coordinate $z$ and a single modulus field $τ$, playing the role of a flavon transforming under a finite modular symmetry. We then consider 10d orbifolds with three factorizable tori, each defined by one complex coordinate $z_i$ and involving the three moduli fields $τ_1, τ_2, τ_3$ transforming under three finite modular groups. Assuming supersymmetry, consistent with the holomorphicity requirement, we consider all 10d orbifolds of the form $(\mathbb{T}^2)^3/(\mathbb{Z}_N\times\mathbb{Z}_M)$, and list those which have fixed values of the moduli fields (up to an integer). The key advantage of such 10d orbifold models over 4d models is that the values of the moduli are not completely free but are constrained by geometry and symmetry. To illustrate the approach we discuss a 10d modular seesaw model with $S_4^3$ modular symmetry based on $(\mathbb{T}^2)^3/(\mathbb{Z}_4\times\mathbb{Z}_2)$ where $τ_1=i,\ τ_2=i+2$ are constrained by the orbifold, while $τ_3=ω$ is determined by imposing a further remnant $S_4$ flavour symmetry, leading to a highly predictive example in the class CSD$(n)$ with $n=1-\sqrt{6}$.

Demographics and access to specialized head and neck cancer centers may affect head and neck cancer patients' (HNCP) outcomes. Here, we compare epidemiological indicators and outcomes of HNCP in rural and urban Germany. Patients and Methods In a retrospective analysis of data from the Center for Cancer Registry Data (ZfKD) between 2002 and 2017, 212,920 HNCP were included. Incidence, demographics, travel distance to specialized centers, and ground values were compared between rural and urban areas with a focus on their association with patient outcomes. Results The mean age of HNCP was significantly higher in urban areas (mean difference = 1.4 years; p < 0.0001), but increased at a comparable rate (p = 0.26) in rural and urban areas during the observation period. Gender imbalance was higher in rural areas (mean ratio of men/women: 4.1 vs. 3.1; p < 0.0001), but showed a comparable trend toward equilibration in both, rural and urban districts (p = 0.46). The portion of HNCP of the entire HNCP population living in urban areas increased from 55.9% in the year 2002 to 76.4% in the year 2017. There was no significant difference or change in the ratio of advanced to low UICC stage during the observation period (p = 0.26). However, travel distances to medical centers were higher in rural areas, especially (p < 0.0001) in East Germany. Median survival of HNCP in rural areas was significantly lower than in urban areas (42 months [SEM = 0.7; CI: 40.5–43.5] vs. 54 months [SEM = 1.2; CI: 51.7–56.3]; p < 0.0001) in East Germany, whereas in West Germany no significant difference was observed (59 months [SEM = 0.8; CI: 57.4–60.6] vs. 60 months [SEM = 0.5; CI: 59.0–61.0]; p = 0.15). Conclusions Place of residence contributes to survival outcome of HNCP. Access to specialized care and socioeconomic factors could be improved in East Germany.

description: Gibt es schmale und breite Parabeln? Diese Frage erzeugt einen kognitiven Konflikt, der einen Zugang zur Quadratur der Parabel ermöglicht, welcher uns aus der Literatur nicht bekannt ist. Zunächst stellen wir zwei klassische Methoden von Archimedes zur Quadratur der Parabel vor. Dann verfolgen wir eine Analogie zu einer Idee des flämischen Jesuiten Gregorius van St-Vincent (1584-1667) zum Logarithmus und zur Berechnung des Volumens eines allgemeinen Kegels von Frits Beukers (1953). Dies liefert uns einen überraschenden und für die Mittelstufe geeigneten Zugang zur Parabelquadratur, der Gelegenheiten zur Verallgemeinerung bietet. An diesem Beispiel wird deutlich, wie reich die Vielfalt an möglichen Qualitäten mathematischer Bewusstheit (Kaenders & Kvasz, 2011) ist. Wir sehen Möglichkeiten, kontextuelle (Hebelgesetz), manipulative (nachrechnen in Koordinaten), instrumentelle (mit DGS), diagrammatische (Archimedische Dreiecke, Zeichnung der Waage), experimentelle (Flächen in DGS angeben lassen), logische und theoretische Bewusstheit zu erlangen – von intuitiver, strategischer, imitativer und sozialer Bewusstheit mal ganz abgesehen. In der Schule spielen Parabeln als Graphen quadratischer Funktionen eine wichtige Rolle – auch, wenn man inzwischen das Wort 'Parabel' (wie übrigens auch das Wort 'Primzahl') in den Kernlehrplänen des Landes NRW und anderswo vergeblich sucht. Die Beschäftigung mit der Parabel gehört seit Jahrtausenden aus guten Gründen zum Grundkanon jedes einführenden Mathematikkurses.

description: We construct the four-derivative supersymmetric extension of $(1,0), 6D$ supergravity coupled to Yang-Mills and hypermultiplets. The hypermultiplet scalars are taken to parametrize the quaternionic projective space $Hp(n)=Sp(n,1)/Sp(n)\times Sp(1)_R$. The hyperscalar kinetic term is not deformed, and the quaternionic Kähler structure and symmetries of $Hp(n)$ are preserved. The result is a three parameter Lagrangian supersymmetric up to first order in these parameters. Considering the case of $Hp(1)$ we compare our result with that obtained from the compactification of $10D$ heterotic supergravity on four-torus, consistently truncated to $N=(1,0)$, in which the hyperscalars parametrize $SO(4,1)/SO(4)$. We find that depending on how $Sp(1) \subset Sp(1,1)$ is embedded in $SO(4)$, the results agree for a specific value of the parameter that governs the higher derivative hypermultiplet couplings.

description: Since the first case of AIDS was recognized in America in 1981, HIV/AIDS has spread rapidly throughout the world. Different studies showed that a great proportion of people living with HIV/AIDS do not know that they carry the virus making VCT service underutilized. However, the reasons for young people for not taking VCT services are not well known. Moreover, University students fall within the most sexually active and high HIV risk group. This study tried to assess the reasons why Bahir Dar University students prefer to or not to take HIV test. This study was conducted from March - April 2008 among Bahir Dar University undergraduate students to assess the factors affecting voluntary counseling and testing uptake. The study design was descriptive cross-sectional. Stratified random sampling was applied to select samples. A standardized questionnaire was used after pre-test to collect quantitative data. Data entry and analysis was done using SPSS. A total of 360 students participated in the study of whom 255 were males. Majority (90.6%) were within the age range of 18 to 23 years. The mean age was 21.26(± sd 1.987). Most of the respondents (95.3%) were single. The study revealed that 38.6% of the study participants had undergone HIV test. Stepwise multivariate analysis showed that being female, second year or above, starting sexual intercourse and knowledge about VCT location were positively associated likelihood of having had HIV testing. Respondents with stigmatizing attitude were less likely to utilize the service. The study shows that stigma still plays a major role as a barrier for utilization of HIV testing services. The University should intensify activities pertaining to curbing stigma and discrimination so that the willingness of students for HIV counseling and testing could be paralleled with actual use of HIV testing.

description: Prediction performance of a risk scoring system needs to be carefully assessed before its adoption in clinical practice. Clinical preventive care often uses risk scores to screen asymptomatic population. The primary clinical interest is to predict the risk of having an event by a pre-specified future time $t_0$. Prospective accuracy measures such as positive predictive values have been recommended for evaluating the predictive performance. However, for commonly used continuous or ordinal risk score systems, these measures require a subjective cutoff threshold value that dichotomizes the risk scores. The need for a cut-off value created barriers for practitioners and researchers. In this paper, we propose a threshold-free summary index of positive predictive values that accommodates time-dependent event status. We develop a nonparametric estimator and provide an inference procedure for comparing this summary measure between competing risk scores for censored time to event data. We conduct a simulation study to examine the finite-sample performance of the proposed estimation and inference procedures. Lastly, we illustrate the use of this measure on a real data example, comparing two risk score systems for predicting heart failure in childhood cancer survivors.

description: The past decade has seen significant progress on the direct detection and characterization of young, self-luminous giant planets at wide orbital separations from their host stars. Some of these planets show evidence for disequilibrium processes like transport-induced quenching in their atmospheres; photochemistry may also be important, despite the large orbital distances. These disequilibrium chemical processes can alter the expected composition, spectral behavior, thermal structure, and cooling history of the planets, and can potentially confuse determinations of bulk elemental ratios, which provide important insights into planet-formation mechanisms. Using a thermo/photochemical kinetics and transport model, we investigate the extent to which disequilibrium chemistry affects the composition and spectra of directly imaged giant exoplanets. Results for specific "young Jupiters" such as HR 8799 b and 51 Eri b are presented, as are general trends as a function of planetary effective temperature, surface gravity, incident ultraviolet flux, and strength of deep atmospheric convection. We find that quenching is very important on young Jupiters, leading to CO/CH4 and N2/NH3 ratios much greater than, and H2O mixing ratios a factor of a few less than, chemical-equilibrium predictions. Photochemistry can also be important on such planets, with CO2 and HCN being key photochemical products. Carbon dioxide becomes a major constituent when stratospheric temperatures are low and recycling of water via the H2 + OH reaction becomes kinetically stifled.

description: We reconsider the Hamiltonian reduction of the action for three dimensional AdS supergravity and $W_3$ higher spin AdS gravity in the Chern-Simons formulation under asymptotically anti-de Sitter boundary conditions. We show that the reduction gives two copies of chiral bosons on the boundary. In particular, we take into account the holonomy of the Chern-Simons connection which manifests itself as zero mode of the momentum of the boundary chiral boson. We provide an equivalent formulation of the boundary action which we claim to be the geometric action on symplectic leaves of a (super-)Virasoro or a higher spin $W_N$ Poisson manifold in the case of supergravity or higher spin gravity respectively, where the intersection of leaves (given in terms of leaves representatives) can be identified as the bulk holonomy. This concludes the extension to non-linear algebras where the notion of coadjoint representation is not well-defined. The boundary Hamiltonian depends on a choice of boundary conditions and is equivalent to the Schwarzian action for corresponding Brown-Henneaux boundary conditions. We make this connection explicit in the extended supersymmetric case. Moreover, we discuss the geometric action in the case of $W_3$ AdS$_3$ gravity in both $\mathfrak{sl}(3)$ highest weight representations based on principal and diagonal $\mathfrak{sl}(2)$ embeddings.

description: The rich thermotropic behavior of lipid bilayers is addressed using phenomenological theory informed by many experiments. The most recent experiment not yet addressed by theory has shown that the tilt modulus in DMPC lipid bilayers decreases dramatically as the temperature is lowered toward the main transition temperature TM . It is shown that this behavior can be understood by introducing a simple free energy functional for tilt that couples to the area per molecule. This is combined with a chain melting free energy functional in which the area is the primary order parameter that is the driver of the main transition. Satisfactory agreement with experiment is achieved with values of the model parameters determined by experiments, but the transition is directly into the gel phase. The theory is then extended to include the enigmatic ripple phase by making contact with the most recent experimentally determined ripple structure.

description: Highly-loaded transmission components like gears are case hardened for most applications to reach a load adapted strength. The surface layer microstructure as a function of heat treatment decisively determines the achievable load-bearing properties of the component as well as the technological limits of gear grinding. Against this background, this paper deals with the machinability (discontinuous proﬁle grinding) of differently (carburizing and carbonitriding) case-hardened gears with various multi-phase microstructures and improved load-carrying capacity. Therefore, effects of different material phases, precipitates and their distribution in the surface layer on the gear-grinding process will be discussed.
