description: We present an effcient Monte-Carlo method for lattice glass models which are characterized by hard constraint conditions. The basic idea of the method is similar to that of the $N$-fold way method. By using a list of sites into which we can insert a particle, we avoid trying a useless transition which is forbidden by the constraint conditions. We applied the present method to a lattice glass model proposed by Biroli and M{é}zard. We first evaluated the efficiency of the method through measurements of the autocorrelation function of particle configurations. As a result, we found that the efficiency is much higher than that of the standard Monte-Carlo method. We also compared the efficiency of the present method with that of the $N$-fold way method in detail. We next examined how the efficiency of extended ensemble methods such as the replica exchange method and the Wang-Landau method is inflnuenced by the choice of the local update method. The results show that the efficiency is considerably improved by the use of efficient local update methods. For example, when the number of sites $N_{\rm site}$ is 1024, the ergodic time $τ_{\rm E}$ of the replica exchange method in the grand-canonical ensemble, which is the average round-trip time of a replica in chemical-potential space, with the present local update method is more than $10^2$ times shorter than that with the standard local update method. This result shows that the efficient local update method is quite important to make extended ensemble methods more effective.

Superfluidity and collective modes in Rashba spin-orbit coupled Fermi gases

description: We present a theoretical study of the superfluidity and the corresponding collective modes in two-component atomic Fermi gases with s-wave attraction and synthetic Rashba spin-orbit coupling. The general effective action for the collective modes is derived from the functional path integral formalism. By tuning the spin-orbit coupling from weak to strong, the system undergoes a crossover from an ordinary BCS/BEC superfluid to a Bose-Einstein condensate of rashbons. We show that the properties of the superfluid density and the Anderson-Bogoliubov mode manifest this crossover. At large spin-orbit coupling, the superfluid density and the sound velocity become independent of the strength of the s-wave attraction. The two-body interaction among the rashbons is also determined. When a Zeeman field is turned on, the system undergoes quantum phase transitions to some exotic superfluid phases which are topologically nontrivial. For the two-dimensional system, the nonanalyticities of the thermodynamic functions and the sound velocity across the phase transition are related to the bulk gapless fermionic excitation which causes infrared singularities. The superfluid density and the sound velocity behave nonmonotonically: they are suppressed by the Zeeman field in the normal superfluid phase, but get enhanced in the topological superfluid phase. The three-dimensional system is also studied.

description: Real physical systems with reflective and rotational symmetries such as viruses, fullerenes and quasicrystals have recently been modeled successfully in terms of three-dimensional (affine) Coxeter groups. Motivated by this progress, we explore here the benefits of performing the relevant computations in a Geometric Algebra framework, which is particularly suited to describing reflections. Starting from the Coxeter generators of the reflections, we describe how the relevant chiral (rotational), full (Coxeter) and binary polyhedral groups can be easily generated and treated in a unified way in a versor formalism. In particular, this yields a simple construction of the binary polyhedral groups as discrete spinor groups. These in turn are known to generate Lie and Coxeter groups in dimension four, notably the exceptional groups D_4, F_4 and H_4. A Clifford algebra approach thus reveals an unexpected connection between Coxeter groups of ranks 3 and 4. We discuss how to extend these considerations and computations to the Conformal Geometric Algebra setup, in particular for the non-crystallographic groups, and construct root systems and quasicrystalline point arrays. We finally show how a Clifford versor framework sheds light on the geometry of the Coxeter element and the Coxeter plane for the examples of the two-dimensional non-crystallographic Coxeter groups I_2(n) and the three-dimensional groups A_3, B_3, as well as the icosahedral group H_3.

description: Несмотря на то, что Творческий центр Калоферского коклюшечного кружева - это не музей в прямом смысле слова, в нем тем не менее содержится несколько выставок, которые чрезвычайно интересны и новаторски для города. Эти выставки свидетельствуют об исторической значимости Калофера для истории Болгарии. В открывшемся в 2018 году Творческом центре Калоферского коклюшечного кружева находится «Золотой фонд» калоферского кружева, созданный в 1999 году, но до сих пор находящийся в очень плохом состоянии. Первоначальная идея заключалась в том, чтобы создать место, где возабновилась бы работа по восстановлению забытых традиций плетения коклюшечного кружева, показывая туристам и гостям города это уникальное место и уникальное кружево, в том числе и говоря о том большом историческом значении, которое оно имеет для развития Калофера после освобождения Болгарии от османского владычества. Впоследствии центр приобрел совершенно другой вид, экспозиции увеличивались и обновлялись. На выставке демонстрируются старые классические модели, а также образцы из других стран. Сотрудники центра часто обновляют внешний вид залов и всегда есть что-то новое и интересное, что можно увидеть в стенах центра. Благодаря попечителям есть возможность оформить центр в особом стиле, подходящем для демонстрации образцов разных видов кружевного искусства. Менее чем за год сувенирный магазин в центре утроил количество предлагаемых товаров и сделал огромный шаг в сторону онлайн-покупок. Создав веб-сайт, у творческого центра появилась возможность продавать работы многих художников, как из Калофера, так и со всей страны. В прошлом году центр изменил свой внешний вид и с целью расширения возможностей для получения прибыли был создан специальный уголок, где можно заказать горячие и освежающие напитки. Эта дополнительная деятельность требует больше средств и не приносит прибыли. На данном этапе развития Творческого центра открываются исключительные возможности для популяризации кружевного искусства в нашей стране. Поэтому команда центра работает над несколькими амбициозными проектами, чтобы показать туристам, посещающим город, что-то необычное, а также поддержать развитие текстильного искусства и, в частности, искусства плетения коклюшечного кружева. В век Интернета и постоянного общения такое учреждение, которому сложно найти финансирование со стороны государства, должно использовать все возможные рычаги для выполнения своих целей и миссии. Команда центра не только привлекает публику, которая посещает центр и наслаждается волшебством текстильного искусства, но и ищет разные возможности для продвижения центра и искусства, которое можно увидеть внутри. Цифровой маркетинг - это инструмент и непрерывный процесс, который может привести к новым рынкам, новым посетителям и любителям этого интересного и живого искусства.

description: We investigate synthesis of a hyperfine spin lattice in an atomic Bose-Einstein condensate, with two hyperfine spin components, inside a one-dimensional high-finesse optical cavity, using off-resonant superradiant Raman scattering. Spatio-temporal evolution of the relative population of the hyperfine spin modes is examined numerically by solving the coupled cavity-condensate mean field equations in the dispersive regime. We find, analytically and numerically, that beyond a certain threshold of the transverse laser pump, Raman superradiance and self-organization of the hyperfine spin components simultaneously occur and as a result a magnetic lattice is formed. The effects of an extra laser pump parallel to the cavity axis and the time-dependence of the pump strength on the synthesis of a sharper lattice are also addressed.

description: We present the first unquenched, continuum limit, lattice QCD results for the matrix elements of the operators describing neutral kaon oscillations in extensions of the Standard Model. Owing to the accuracy of our calculation on ΔS=2 weak Hamiltonian matrix elements, we are able to provide a refined Unitarity Triangle analysis improving the bounds coming from model independent constraints on New Physics. In our non-perturbative computation we use a combination of Nf=2 maximally twisted sea quarks and Osterwalder-Seiler valence quarks in order to achieve both O(a)-improvement and continuum-like renormalization properties for the relevant four-fermion operators. The calculation of the renormalization constants has been performed non-perturbatively in the RI-MOM scheme. Based on simulations at four values of the lattice spacing and a number of quark masses we have extrapolated/interpolated our results to the continuum limit and physical light/strange quark masses.

 This candidate species was named Platypelis sp. aff. mavomavo 1 by Glaw & Vences (2007), P. sp. 3 by Andreone et al. (2005b) and Wollenberg et al. (2008), and Platypelis sp. 8 by Vieites et al. (2009). It was only collected at Antsahamanara campsite (in the Manarikoba forest) on the western slope of Tsaratanana. One voucher specimen is preserved in the museum of Torino (Italy) as MRSN A2630. Based on photographs in life (Figs. 3 and 6), the candidate species is characterized by a contrasted dorsal coloration with yellow patches behind the forelimb insertions and yellow color on the belly, while the throat and chest are marbled with brown. Nothing is known on the variation, natural history or vocalizations of this frog. Its unique color pattern and strong genetic differentiation strongly suggest it is an unnamed species. For the present study, we had no voucher specimens of this candidate species available for further examination.

description: The no-boundary wave function of quantum gravity usually assigns only very small probability to long periods of inflation. This was a reason to doubt about the no-boundary wave function to explain the observational universe. We study the no-boundary proposal in the context of multi-field inflation to see whether the number of fields changes the situation. For a simple model, we find that indeed the no-boundary wave function can give higher probability for sufficient inflation, but the number of fields involved has to be very high.

description: Between the preservation of aquatic ecosystems and the demand for water collection from rivers, complex problems arise for water resource management. To enable the continuity of the ecological functions offered by the water, a flow that sustains the aquatic ecosystem has to be maintained. This study aims to compare different methods of ecological flow calculation and their applicability in an urbanised watershed, discussing the resulting environmental and social implications in the context of a developing country. The 7Q10, Northern Great Plains Resource Program, and Ecological Hydraulic Radius approaches were used. The 7Q10 was chosen because it is a method widely used in Brazil and the others for their ecological considerations and the availability of data for the study area. The results showed that the daily flow crossing the rivers of the urban watershed is not enough to promote the maintenance of the aquatic ecosystem. The 7Q10 method presented an admissible ecological flow (0.38 m3/s) due to the absence of ecological parameters in the modelling and this differed from the other approaches. We highlight the need to develop an ecologically sustainable water management program for the recovery and revitalisation of the waterways in the basin.

description: We examine a minimal model for an active colloidal fluid in the form of self-propelled Brownian hard spheres that interact purely through excluded volume. Despite the absence of an aligning interaction, this system shows the signature behaviors of an active fluid, including anomalous number fluctuations and phase separation behavior. Using simulations and analytic modeling, we quantify the phase diagram and separation kinetics. The dense phase is a unique material that we call an active hexatic, which exhibits the structural signatures of a crystalline solid near the crystal-hexatic transition point, but the rheological and transport properties associated with a viscoelastic fluid.

Group Iterative Spectrum Thresholding for Super-Resolution Sparse Spectral Selection

description: Recently, sparsity-based algorithms are proposed for super-resolution spectrum estimation. However, to achieve adequately high resolution in real-world signal analysis, the dictionary atoms have to be close to each other in frequency, thereby resulting in a coherent design. The popular convex compressed sensing methods break down in presence of high coherence and large noise. We propose a new regularization approach to handle model collinearity and obtain parsimonious frequency selection simultaneously. It takes advantage of the pairing structure of sine and cosine atoms in the frequency dictionary. A probabilistic spectrum screening is also developed for fast computation in high dimensions. A data-resampling version of high-dimensional Bayesian Information Criterion is used to determine the regularization parameters. Experiments show the efficacy and efficiency of the proposed algorithms in challenging situations with small sample size, high frequency resolution, and low signal-to-noise ratio.

description: Climate change and increasing water demand in urban environments necessitate planning water utility companies’ finances. Traditionally, methods to estimate the direct water utility business interruption costs (WUBIC) caused by droughts have not been clearly established. We propose a multi-driver assessment method. We project the water yield using a hydrological model driven by regional climate models under radiative forcing scenarios. We project water demand under stationary and non-stationary conditions to estimate drought severity and duration, which are linked with pricing policies recently adopted by the Sao Paulo Water Utility Company. The results showed water insecurity. The non-stationary trend imposed larger differences in the drought resilience financial gap, suggesting that the uncertainties of WUBIC derived from demand and climate models are greater than those associated with radiative forcing scenarios. As populations increase, proactively controlling demand is recommended to avoid or minimize reactive policy changes during future drought events, repeating recent financial impacts.

description: Sustainable urban stormwater management (SUSM) is essential to urban sustainability. However, barriers to adopting it are observed even in places where SUSM is more widespread. Recent studies have evaluated strategies for overcoming some barriers. However, no study has systematically analyzed the strategies available for overcoming the most common barriers in developing countries. Thus, this article aimed to provide a literature review on these strategies. Ninety-two documents were evaluated, resulting in eight solution strategies, detailed by 80 implementation measures. The interrelationships among the solution strategies and their applicability to overcome the SUSM-related barriers were evaluated. This analysis showed that the solution strategies are interdependent, so it would be inefficient to adopt them in isolation. On the other hand, adopting a strategy can help overcome several barriers, also enhancing other strategies and urban issues. The availability of this systematized information can help to break through common barriers, optimizing efforts to adopt SUSM.

description: Understanding the major drivers of runoff water quality in urban areas is important for sustainable water management. In this study, runoff water quality in a catchment in Colombia and another in Brazil was monitored and related to rain, and meteorological variables through correlation and principal component analysis. High correlations were found between event mean concentration of total suspended solids (TSS) and total phosphorus (TP), as well as with total Kjeldahl nitrogen (TKN) and total organic carbon (TOC). The results indicated that TSS and TP were related to sediment transport in the catchment, while NTK and TOC were derived from point sources (improper wastewater disposal). Rain depth, maximum specific discharge, air temperature, and solar radiation were the main factors explaining variability of water quality. These results contribute to a better understanding of local processes driving runoff water quality, and bring valuable insights for modelling and management of stormwater in urban catchments.

description: A linear different operator L is called weakly hypoelliptic if any local solution u of Lu=0 is smooth. We allow for systems, that is, the coefficients may be matrices, not necessarily of square size. This is a huge class of important operators which cover all elliptic, overdetermined elliptic, subelliptic and parabolic equations. We extend several classical theorems from complex analysis to solutions of any weakly hypoelliptic equation: the Montel theorem providing convergent subsequences, the Vitali theorem ensuring convergence of a given sequence and Riemann's first removable singularity theorem. In the case of constant coefficients we show that Liouville's theorem holds, any bounded solution must be constant and any L^p-solution must vanish.

description: Service level of water supply systems (WSS) was assessed across in Ogun State, Southwest Nigeria. The WSS included: self-supply systems, communal water supply systems, and public water systems. Five service level indicators (access, quality, management, cost, and reliability) were assessed using structured questionnaires, targeting WSS users and owners in two categories: owners/resident users and non-resident users. Results show that owners/resident users restricted access of non-resident users to water assets, hence reducing adequate service level. Post-collection treatment was practiced by some users, using sodium hypochlorite solutions. Management and costs of WSS are borne by owners/resident users; costs borne by non-resident users is only from purchase of water. Reliability of WSS is hampered by geology and climatic seasonal variations as some WSS dried up during the off-rain season. Poor access to water has been identified as a major challenge facing non-resident users, amplified by limited coverage area of public water supply systems.

description: We consider the numerical approximation of the spectrum of a second-order elliptic eigenvalue problem by the hybridizable discontinuous Galerkin (HDG) method. We show for problems with smooth eigenfunctions that the approximate eigenvalues and eigenfunctions converge at the rate 2k+1 and k+1, respectively. Here k is the degree of the polynomials used to approximate the solution, its flux, and the numerical traces. Our numerical studies show that a Rayleigh quotient-like formula applied to certain locally postprocessed approximations can yield eigenvalues that converge faster at the rate 2k + 2 for the HDG method as well as for the Brezzi-Douglas-Marini (BDM) method. We also derive and study a condensed nonlinear eigenproblem for the numerical traces obtained by eliminating all the other variables.

description: This study presents a resilience-based evaluation of an urban drainage system (UDS) under the impact of functional and structural failure modes. Resilience based analysis is carried out using SWMM for a part of Gurugram City of Haryana, India. For simulating the drainage system response, half-hourly rainfall data available from GPM-IMERG was utilized to estimate the design storm of suitable duration. Sensitivity analysis is carried out to overcome the problem of lack of in-depth data to perform model calibration and validation. Besides, a comparison of three different estimation approaches of subcatchment width, an important SWMM parameter, is also presented. Different rainfall and urban growth scenarios were considered to analyse the drainage system's functional and structural resilience. For the studied UDS, a total of 22 vulnerable nodes were identified through the structural resilience approach, and the functional resilience approach revealed that urbanization has more pronounced effects on UDS than climate change.

description: We discuss a deformation of Sasakian structure in the presence of totally skew-symmetric torsion by introducing odd dimensional manifolds whose metric cones are Kähler with torsion. It is shown that such a geometry inherits similar properties to those of Sasakian geometry. As an example of them, we present an explicit expression of local metrics and see how Sasakian structure is deformed by the presence of torsion. We also demonstrate that our example of the metrics admits the existence of hidden symmetries described by non-trivial odd-rank generalized closed conformal Killing-Yano tensors. Furthermore, using these metrics as an {\it ansatz}, we construct exact solutions in five dimensional minimal (un-)gauged supergravity and eleven dimensional supergravity. Finally, we discuss the global structures of the solutions and obtain regular metrics on compact manifolds in five dimensions, which give natural generalizations of Sasaki--Einstein manifolds $Y^{p,q}$ and $L^{a,b,c}$. We also discuss regular metrics on non-compact manifolds in eleven dimensions.

description: Die Dissertation besteht aus drei
      Arbeiten. In der Arbeit „Testing for the number of states in
      hidden Markov models“ verallgemeinern wir vorhandene
      Testverfahren von Mischungsmodellen auf HMMs, indem wir
      penalisierte quasi-Likelihood-Quotienten-Tests untersuchen.
      Falls die zustandsbedingte Verteilung des HMMs univariat ist
      und gewisse Regularitätsbedingungen erfüllt sind, können die
      vorgestellten Testverfahren dazu verwendet werden, die Anzahl
      der Zustände k eines HMMs festzustellen. In der Arbeit
      „Hidden Markov Models with state-dependent mixtures“
      analysieren wir die Abhängigkeitsstruktur von Hidden Markov
      Modellen mit zustandsbedingten endlichen Mischungsmodellen.
      Unsere Ergebnisse haben Anwendungen für die Modellwahl und
      das modellbasierte Clustering. Für beide Aufgaben schlagen
      wir je einen Algorithmus vor. In der Arbeit „Peaks vs
      Components“ wenden wir endliche Mischungsmodelle an, um
      Wohlfahrtsgruppen von Ländern der gesamten Welt zu
      analysieren. Wir betrachten das BIP pro Kopf von 190 Ländern
      in den Jahren 1970 bis 2009.
description: The thesis consists of three
      papers. In the paper “Testing for the number of states in
      hidden Markov models” we generalize existing testing
      procedures for i.i.d. mixture models to hidden Markov models
      by considering penalized quasi-likelihood ratio tests. They
      can be applied in order to assess the number of states k of a
      hidden Markov model with univariate state-dependent
      distribution fulfilling certain regularity conditions. In the
      paper “Hidden Markov Models with state-dependent mixtures” we
      analyze the dependence structure of hidden Markov models with
      state-dependent finite mixtures. Our results have
      applications to model selection as well as to model-based
      clustering. We propose algorithms for both purposes. In the
      paper “Peaks vs Components” we analyze welfare groups of
      countries all over the world by applying finite mixture
      models to the GDP per capita of 190 countries from 1970 to
      2009.

description: We report an angle-resolved photoemission spectroscopy (ARPES) study on IrTe2 which exhibits an interesting lattice distortion below 270 K and becomes triangular lattice superconductors by suppressing the distortion via chemical substitution or intercalation. ARPES results at 300 K show multi-band Fermi surfaces with six-fold symmetry which are basically consistent with band structure calculations. At 20 K in the distorted phase, whereas the flower shape of the outermost Fermi surface does not change from that at 300 K, topology of the inner Fermi surfaces is strongly modified by the lattice distortion. The Fermi surface reconstruction by the distortion depends on the orbital character of the Fermi surfaces, suggesting importance of Ir 5d and/or Te 5p orbital symmetry breaking.

description: Sub-daily rainfall datasets are not commonly available in developing countries, but the annual maximum daily rainfall (Pma) often is. This article evaluates the ratio between 1440 min of rainfall and the Pma, as well as the sub-daily rainfall ratio from different origins as disaggregation coefficients for modeling the intensity-duration-frequency (IDF) curves in the metropolitan area of Belo Horizonte, Brazil. Non-parametric tests were previously applied to the series to verify stationarity, homogeneity, randomness, and independence. It was verified via Student’s t-test and identity test models that there is a significant difference between the IDF curves from the sub-daily rainfall dataset and disaggregation rainfall dataset. Nevertheless, the model performance indexes between the results of IDF curves indicate the errors are acceptable, thus guaranteeing an alternative tool in places where there are no sub-daily rainfall datasets available. Sub-daily rainfall ratios can be used as disaggregation coefficients on a local and regional scale.
Reddit, The Manosphere and The Male Complaint
Creators: name: Copland, Simon
Publisher: name: The Australian National University

description: This thesis examines the connective tissue that binds individuals together in the 'manosphere' - a collective of online platforms and forums devoted to men's interests, life philosophies and anti-feminist ideology. Members of the manosphere have been involved in misogynistic and violent harassment campaigns and attacks, including several terrorist incidents. Motivated by concerns over this violence, alongside interest in growing debate about masculinity in modern society and politics, this thesis seeks to understand how the manosphere arose, why men participate, and what it provides for individuals. Using a combination of large-scale data analysis alongside in-depth qualitative readings of content, I study three manosphere communities on the social news and networking site Reddit. Inspired by Lauren Berlant's ground-breaking book The Female Complaint, I identify the manosphere as a mass-cultural intimate public - a space characterised by a belief that individuals already share a worldview, emotional knowledge and common historical experience. This intimate public is situated within and influenced by the network society, a post-Fordist economic structure in which social functions and processes are organised primarily around networks. The manosphere enacts a belief that men's lives are not just their own, but an experience shared by other men. Individuals bind over an attachment to white heteronormative ideals of love and a complaint about the failures of said love, alongside men's broader position in society - The Male Complaint. While not necessarily rational or well founded, this complaint provides an affective pull for men, binding them together through a collective identity as injured subjects. Drawing on Wendy Brown's analysis of ressentiment and nihilism, alongside Berlant's notion of Cruel Optimism, the thesis then examines the consequences of this complaint for participants and society more broadly. Specifically, I conduct the first usage of social network analysis (SNA) on the manosphere on Reddit to explore the structure of community within and whether it achieves the promises made by the network society. Through charting the manosphere as an affective space of attachment and identification, this thesis provides a unique entry point into the space. The thesis chronicles it not as a new aberration, but instead part of an ongoing historical current. This provides a strong basis through which to understand the connective tissue that attaches men to the manosphere, the social and economic structures that have led to its rise, and the nature of the misogyny within.
