description: Sign language recognition is a challenging problem where signs are identified by simultaneous local and global articulations of multiple sources, i.e. hand shape and orientation, hand movements, body posture, and facial expressions. Solving this problem computationally for a large vocabulary of signs in real life settings is still a challenge, even with the state-of-the-art models. In this study, we present a new largescale multi-modal Turkish Sign Language dataset (AUTSL) with a benchmark and provide baseline models for performance evaluations. Our dataset consists of 226 signs performed by 43 different signers and 38,336 isolated sign video samples in total. Samples contain a wide variety of backgrounds recorded in indoor and outdoor environments. Moreover, spatial positions and the postures of signers also vary in the recordings. Each sample is recorded with Microsoft Kinect v2 and contains RGB, depth, and skeleton modalities. We prepared benchmark training and test sets for user independent assessments of the models. We trained several deep learning based models and provide empirical evaluations using the benchmark; we used CNNs to extract features, unidirectional and bidirectional LSTM models to characterize temporal information. We also incorporated feature pooling modules and temporal attention to our models to improve the performances. We evaluated our baseline models on AUTSL and Montalbano datasets. Our models achieved competitive results with the state-of-the-art methods on Montalbano dataset, i.e. 96.11% accuracy. In AUTSL random train-test splits, our models performed up to 95.95% accuracy. In the proposed user-independent benchmark dataset our best baseline model achieved 62.02% accuracy. The gaps in the performances of the same baseline models show the challenges inherent in our benchmark dataset. AUTSL benchmark dataset is publicly available at https://cvml.ankara.edu.tr.

description: We show how the quality of decisions based on the aggregated opinions of the crowd can be conveniently studied using a sample of individual responses to a standard IQ questionnaire. We aggregated the responses to the IQ questionnaire using simple majority voting and a machine learning approach based on a probabilistic graphical model. The score for the aggregated questionnaire, Crowd IQ, serves as a quality measure of decisions based on aggregating opinions, which also allows quantifying individual and crowd performance on the same scale. We show that Crowd IQ grows quickly with the size of the crowd but saturates, and that for small homogeneous crowds the Crowd IQ significantly exceeds the IQ of even their most intelligent member. We investigate alternative ways of aggregating the responses and the impact of the aggregation method on the resulting Crowd IQ. We also discuss Contextual IQ, a method of quantifying the individual participant's contribution to the Crowd IQ based on the Shapley value from cooperative game theory.

description: We discuss spin-$\frac12$ Heisenberg antiferromagnet on simple square lattice in magnetic field $H$ using recently proposed bond-operator technique. It is well known that magnetically ordered phases of quantum magnets are well described at least qualitatively by the conventional spin-wave theory that only introduces quantum corrections into the classical solution of the problem. We observe that quantum fluctuations change drastically dynamical properties of the considered model at $H$ close to its saturation value: the dynamical structure factor shows anomalies corresponding to Green's function poles which have no counterparts in the spin-wave theory. That is, quantum fluctuations produce multiple short-wavelength magnon modes not changing qualitatively the long-wavelength spin dynamics. Our results are in agreement with previous quantum Monte-Carlo simulations and exact diagonalization of finite clusters.

Vízgazdálkodás szempontjából ilyen a csapadék térben és időben egyenlőtlen eloszlása, intenzitásának növekedése, hirtelen bekövetkező árvizek kialakulása, aszályos időszakok sűrűsödése. A kis időegység alatt, hirtelen, nagy mennyiségben lezúduló esővíz részben eróziós károkat, részben árvizeket okozhat. Az utóbbi 10 évben a területen a hőmérséklet 0,5-0,6 °C -kal emelkedett. A 2012. évben az ország más részeihez viszonyítva sokkal magasabb volt az évi abszolút maximumhőmérséklet, a párolgás mennyisége kevesebb volt, mint a sokévi átlag, a vízállások alacsonyabbak voltak. Jelentős veszély rejlik a lefolyás okozta eróziós károk megjelenésében. Jellemző az aszályos, száraz meleg nyár, a hideg, fagyos tél, a tavaszi és őszi évszakok lerövidülése, a hőmérséklet hirtelen emelkedése vagy esése. -------------------------------------------------------------------- It has been proven that the area of Ipoly valley is greatly affected by the global climate change. From a water management point of view such is the spatially and temporally unequal dispersion of precipitation, increase in it’s intensity, sudden emergence of floods and the more frequent occurance of dry seasons. The great amount of torrential rain in a short time might cause erosion damage or partly, floods. In the last 10 years the temperature of the area increased by 0,5-0,6 °C. In 2012 the annual absolute maximum temperature has been much higher, the evaporation has been lower and water levels have been lower compared to other parts of the country. Considerable danger lies in erosional damages caused by water runoff. Droughts, warm summers and cold, frigid winters have become typical along with the shortening of spring and autumn seasons or the sudden raise or fall of temperature.
Effective Theories as Truncated Trans-Series and Scale Separated Compactifications

description: We study the possibility of realizing scale-separated type IIB Anti-de Sitter and de Sitter compactifications within a controlled effective field theory regime defined by low-energy and large (but scale-separated) compactification volume. The approach we use views effective theories as truncations of the full quantum equations of motion expanded in a trans-series around this asymptotic regime. By studying the scalings of all possible perturbative and non-perturbative corrections we identify the effects that have the right scaling to allow for the desired solutions. In the case of Anti-de Sitter, we find agreement with KKLT-type scenarios, and argue that non-perturbative brane-instantons wrapping four-cycles (or similarly scaling effects) are essentially the only ingredient that allows for scale separated solutions. We also comment on the relation of these results to the AdS swampland conjectures. For the de Sitter case we find that we are forced to introduce an infinite number of relatively unsuppressed corrections to the equations of motion, leading to a breakdown of effective theory. This suggests that if de Sitter vacua exist in the string landscape, they should not be thought of as residing within the same effective theory as the AdS or Minkowski compactifications, but rather as defining a separate asymptotic regime, presumably related to the others by a duality transformation.

Evolution and memory in a heritage landscape

Publisher: name: University of British Columbia
Year: 2010

description: Heritage preservation has become a major industry and pastime in North America and Europe. While the preservation movement has traditionally focussed on architectural structures, in recent decades heritage landscapes have been recognized for the wealth of historical, cultural, economic, educational, and ecological information about both the past and the present that they contain. Time and change are critical aspects of the landscape, but tend to be addressed inadequately in heritage landscape preservation practice and guidelines. This is demonstrated by the two disparate approaches, scientific and situated, to heritage landscapes in the field of landscape architecture. This thesis examines the origins, motivations, benefits, issues, and existing Canadian and U S guidelines for the preservation of heritage landscapes, and concludes that an approach that emphasizes memory and evolution of the landscape over static guidelines will create more robust and meaningful places.

description: We calculate the K^{0}-\bar{K}^{0}, B_{d,s}^{0}-\bar{B}_{d,s}^{0} mixing mass differences ΔM_K, ΔM_{d,s} and the CP-violating parameter ε_{K} in the Littlest Higgs (LH) model. For f/v as low as 5 and the Yukawa parameter x_L<0.8, the enhancement of ΔM_{d} amounts to at most 20%. Similar comments apply to ΔM_s and ε_{K}. The correction to ΔM_{K} is negligible. The dominant new contribution in this parameter range, calculated here for the first time, comes from the box diagrams with (W_L^\pm,W_H^\pm) exchanges and ordinary quarks that are only suppressed by the mass of W_H^\pm but do not involve explicit O(v^2/f^2) factors. This contribution is strictly positive. The explicit O(v^2/f^2) corrections to the SM diagrams with ordinary quarks and two W_L^\pm exchanges have to be combined with the box diagrams with a single heavy T quark exchange for the GIM mechanism to work. These O(v^2/f^2) corrections are found to be of the same order of magnitude as the (W_L^\pm,W_H^\pm) contribution but only for x_L approaching 0.8 they can compete with it. We point out that for x_L>0.85 box diagrams with two T exchanges have to be included. Although formally O(v^4/f^4), this contribution is dominant for x_L \approx 1 due to non-decoupling of T that becomes fully effective only at this order. We emphasize, that the concept of the unitarity triangle is still useful in the LH model, in spite of the O(v^2/f^2) corrections to the CKM unitarity involving only ordinary quarks. We demonstrate the cancellation of the divergences in box diagrams that appear when one uses the unitary gauge for W_L^\pm and W_H^\pm.

There are two main directions of development, i.e. the industrial and the sustainable model of agriculture. The first model means a higher intensity of farming, the second one takes into consideration the environmental conditions of production. Therefore, the sustainability level of small agricultural holdings, both in the environmental and the economic aspects was determined. / Synopsis. Polskie rolnictwo musi się zmierzyć z jednym z podstawowych dylematów rozwojowych, jakim jest wybór dalszej ścieżki rozwoju. Obecnie rysują się dwie nadrzędne koncepcje dalszego rozwoju rolnictwa, a mianowicie model rolnictwa industrialnego, który silniej akcentuje zwiększanie intensywności gospodarowania zasobami produkcyjnymi w rolnictwie oraz model rolnictwa zrównoważonego, uwzględniający mocniej wymogi środowiskowe i zdrowotne jako warunki brzegowe produkcji. W związku z powyższym podjęto próbę pomiaru zrównoważenia na poziomie mikroekonomicznym, tzn. gospodarstwa rolnego, zarówno w zakresie przyjazności produkcji rolnej dla środowiska, jak i dochodowości.

Following decay of the photoassociated KRb*, the molecules are detected using two-photon ionization and time-of-flight mass spectroscopy of KRb$^+$. A portion of the metastable triplet molecules thus formed are magnetically trapped. Photoassociative spectra down to 91 cm$^{-1}$ below the K(4$s$) + Rb (5$p_{1/2}$) asymptote have been obtained. We have made assignments to all eight of the attractive Hund's case (c) KRb* potential curves in this spectral region.

description: We study the quantum phase diagram of spinful fermions on kagome lattice with half-filled lowest flat bands. To understand the competition between magnetism, flat band frustration, and repulsive interactions, we adopt an extended $t$-$J$ model, where the hopping energy $t$, antiferromagnetic Heisenberg interaction $J$, and short-range neighboring Hubbard interaction $V$ are considered. In the weak $J$ regime, we identify a fully spin-polarized phase, which can further support the spontaneous Chern insulating phase driven by the short-range repulsive interaction. This phase still emerges with in-plane ferromagnetism, whereas the non-interacting Chern insulator disappears constrained by symmetry. As $J$ gradually increases, the ferromagnetism is suppressed and the system first becomes partially-polarized with large magnetization and then enters a non-polarized phase with the ground state exhibiting vanishing magnetization. We identify this non-polarized phase as an insulator with a nematic charge density wave. In the end, we discuss the potential experimental observations of our theoretical findings.

description: We explore differential and algebraic operations on the exterior product of spinor representations and their twists that give rise to cohomology, the spin cohomology. A linear differential operator $d$ is introduced which is associated to a connection $\nabla$ and a parallel spinor $ζ$, $\nablaζ=0$, and the algebraic operators $D_{(p)}$ are constructed from skew-products of $p$ gamma matrices. We exhibit a large number of spin cohomology operators and we investigate the spin cohomologies associated with connections whose holonomy is a subgroup of $SU(m)$, $G_2$, $Spin(7)$ and $Sp(2)$. In the $SU(m)$ case, we findthat the spin cohomology of complex spin and spin$_c$ manifolds is related to a twisted Dolbeault cohomology. On Calabi-Yau type of manifolds of dimension $8k+6$, a spin cohomology can be defined on a twisted complex with operator $d+D$ which is the sum of a differential and algebraic one. We compute this cohomology on six-dimensional Calabi-Yau manifolds using a spectral sequence. In the $G_2$ and $Spin(7)$ cases, the spin cohomology is related to the de Rham cohomology.

description: Distance education has expanded significantly over the last decade, but the natural sciences have lagged in the implementation of this instructional mode. The abrupt onset of the COVID-19 pandemic left educational institutions scrambling to adapt curricula to distance modalities. With projected effects lasting through the 2020--21 academic year, this problem will not go away soon. Analysis of the literature has elucidated the costs and benefits of, as well as obstacles to, the implementation of e-learning, with a focus on undergraduate physics education. Physics faculty report that a lack of time to learn about research-driven innovation is their primary barrier to implementing it. In response, this paper is intended to help physics lecturers and lab instructors re-think their courses now that distance learning is far more prevalent due to the pandemic. This paper serves as an all-in-one guide of recommendations for successful distanced educational practices, with an emphasis on smartphones and social media. These technologies were chosen for their utility in a virtual environment. Additionally, this paper can be used as a resource for university administrators to adapt to the changing needs associated with new teaching modalities.

description: Hodge representations were introduced by Green-Griffiths-Kerr to classify the Hodge groups of polarized Hodge structures, and the corresponding Mumford-Tate subdomains of a period domain. The purpose of this article is to provide an exposition of how, given a fixed period domain $\mathcal{D}$, to enumerate the Hodge representations corresponding to Mumford-Tate subdomains $D \subset \mathcal{D}$. After reviewing the well-known classical cases that $\mathcal{D}$ is Hermitian symmetric (weight $n=1$, and weight $n=2$ with $p_g = h^{2,0}=1$), we illustrate this in the case that $\mathcal{D}$ is the period domain parameterizing polarized Hodge structures of (effective) weight two Hodge structures with first Hodge number $p_g = h^{2,0} = 2$. We also classify the Hodge representations of Calabi-Yau type, and enumerate the horizontal representations of CY 3-fold type. (The "horizontal" representations those with the property that corresponding domain $D \subset \mathcal{D}$ satisfies the infinitesimal period relation, a.k.a. Griffiths' transversality, and is therefore Hermitian.)

description: L’Appellation d’Origine Contrôlée (AOC) est un des signes d’identification de la qualité et de l’origine géographique existant en France. Le nombre de produits AOC ou AOP (Appellation d’Origine Protégée ; appellation européenne) est en constante augmentation en France comme en Europe. Dans l’Union européenne, les pays les plus concernés par la certification AOC sont la France, l’Italie, la Grèce et l’Espagne. Les AOC, fortement implantées dans les secteurs viticole et fromager, sont également présentes dans d’autres secteurs agroalimentaires tels que la production d’huile et les produits d’origine animale ou végétale. Compte tenu du développement des labels AOC, il est intéressant d’analyser leur potentiel et leur efficacité à créer de la valeur dans les filières alimentaires notamment dans un contexte de diminution du nombre d’entreprises et d’exploitations. Nous synthétisons ici les résultats d’études empiriques portant sur l’utilisation du label AOC dans la filière laitière française. Notre analyse porte sur le label AOC dans le secteur fromager en France, secteur comprenant le plus grand nombre de produits sous AOC après le vin. Le fromage représente 10 % de la valeur des AOC en France et 91 % hors vin. Dans le secteur fromager, la part de l’AOC est de 25 % en valeur en France (15 % en volume) avec 45 fromages certifiés en 2013. La moitié des entreprises fromagères est engagée dans la démarche AOC pour lesquelles l’AOC représente 45 % de la production. Les résultats montrent que les consommateurs ont globalement un faible attachement au label AOC. Cependant l’AOC, qui est adoptée de façon volontaire par les entreprises, contribue au maintien sur le marché des entreprises fromagères de petite taille.

description: Conversational interfaces are currently on the rise: more and more applications rely on a chat-like interaction pattern to increase their acceptability and to improve user experience. Also in the area of questionnaire design and administration, interaction design is increasingly looked at as an important ingredient of a digital solution. For those reasons, we designed and developed a conversational survey tool to administer questionnaires with a colloquial form through a chat-like Web interface. In this paper, we present the evaluation results of our approach, taking into account both the user point of view - by assessing user acceptance and preferences in terms of survey compilation experience - and the survey design perspective - by investigating the effectiveness of a conversational survey in comparison to a traditional questionnaire. We show that users clearly appreciate the conversational form and prefer it over a traditional approach and that, from a data collection point of view, the conversational method shows the same reliability and a higher response quality with respect to a traditional questionnaire.

description: We study the Bjorken x dependence of the virtual photon spin asymmetry in polarized deep inelastic scattering of electrons from hadrons. We use an exactly solved relativistic potential model of the hadron, treating the constituents as independent massless Dirac particles bound to an infinitely massive force center. The potential is chosen to have spin symmetry and a linear radial dependence with spherical symmetry. The effect of interactions of the struck constituent with the remainder of the target on the longitudinal photon asymmetry is demonstrated. In particular, the small-x suppression of the photon asymmetry observed in polarized deep inelastic scattering from the proton is shown to be a consequence of these interactions. The effect of p--wave components of the Dirac wave function, long known to give an important contribution to the spin of hadrons, is explicitly demonstrated through their interference with the s--wave term.

description: We consider smooth Gowdy-symmetric generalised Taub-NUT solutions, a class of inhomogeneous cosmological models with spatial three-sphere topology. They are characterised by existence of a smooth past Cauchy horizon and, with the exception of certain singular cases, they also develop a regular future Cauchy horizon. Several examples of exact solutions were previously constructed, where the initial data (in form of the initial Ernst potentials) are polynomials of low degree. Here, we generalise to polynomial initial data of arbitrary degree. Utilising methods from soliton theory, we obtain a simple algorithm that allows us to construct the resulting Ernst potential with purely algebraic calculations. We also derive an explicit formula in terms of determinants, and we illustrate the method with two examples.

Partition function of two- and three-dimensional Potts ferromagnets for arbitrary values of q>0
Creators: name: Hartmann, A. K.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A new algorithm is presented, which allows to calculate numerically the partition function Z_q of the d-dimensional q-state Potts models for arbitrary real values q>0 at any given temperature T with high precision. The basic idea is to measure the distribution of the number of connected components in the corresponding Fortuin-Kasteleyn representation and to compare with the distribution of the case q=1 (graph percolation), where the exact result Z_1=1 is known. As application, d=2 and d=3-dimensional ferromagnetic Potts models are studied, and the critical values q_c, where the transition changes from second to first order, are determined. Large systems of sizes N=1000^2 respectively N=100^3 are treated. The critical value q_c(d=2)=4 is confirmed and q_c(d=3)=2.35(5) is found.

Khovanov's homology for tangles and cobordisms

description: We give a fresh introduction to the Khovanov Homology theory for knots and links, with special emphasis on its extension to tangles, cobordisms and 2-knots. By staying within a world of topological pictures a little longer than in other articles on the subject, the required extension becomes essentially tautological. And then a simple application of an appropriate functor (a `TQFT') to our pictures takes them to the familiar realm of complexes of (graded) vector spaces and ordinary homological invariants.

Adding Filters to Improve Reservoir Computer Performance

description: Reservoir computers are a type of neuromorphic computer that may be built a an analog system, potentially creating powerful computers that are small, light and consume little power. Typically a reservoir computer is build by connecting together a set of nonlinear nodes into a network; connecting the nonlinear nodes may be difficult or expensive, however. This work shows how a reservoir computer may be expanded by adding functions to its output. The particular functions described here are linear filters, but other functions are possible. The design and construction of linear filters is well known, and such filters may be easily implemented in hardware such as field programmable gate arrays (FPGA's). The effect of adding filters on the reservoir computer performance is simulated for a signal fitting problem, a prediction problem and a signal classification problem.
Improving teleportation of continuous variables by local operations

Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study a continuous-variable (CV) teleportation protocol based on a shared entangled state produced by the quantum-nondemolition (QND) interaction of two vacuum states. The scheme utilizes the QND interaction or an unbalanced beam splitter in the Bell measurement. It is shown that in the non-unity gain regime the signal transfer coefficient can be enhanced while the conditional variance product remains preserved by applying appropriate local squeezing operation on sender's part of the shared entangled state. In the unity gain regime it is demonstrated that the fidelity of teleportation can be increased with the help of the local squeezing operations on parts of the shared entangled state that convert effectively our scheme to the standard CV teleportation scheme. Further, it is proved analytically that such a choice of the local symplectic operations minimizes the noise by which the mean number of photons in the input state is increased during the teleportation. Finally, our analysis reveals that the local symplectic operation on sender's side can be integrated into the Bell measurement if the interaction constant of the interaction in the Bell measurement can be adjusted properly.

description: Recent innovations and progress in machine learning algorithms from the Natural Language Processing (NLP) community have motivated efforts to apply these models and concepts to proteins. The representations generated by trained NLP models have been shown to capture important semantic and structural understanding of proteins encompassing biochemical and biophysical properties, among other key concepts. In turn, these representations have demonstrated application to protein engineering tasks including mutation analysis and design of novel proteins. Here we use this NLP paradigm in a protein engineering effort to further red shift the emission wavelength of the red fluorescent protein mNeptune684 using only a small number of functional training variants ('Low-N' scenario). The collaborative nature of this thesis with the Department of Chemistry and Biomolecular Sciences explores using these tools and methods in the rational design process.

Meibōka and the politics of localism in rural Japan
Creators: name: Craig, Christopher Robin Jamie
Publisher: name: University of British Columbia
Year: 2010

description: The changes that transformed the political and economic centers of Japan so dramatically during the Meiji and Taishō periods were slower to take effect in the rural areas. In these regions tradition persisted alongside social and political change, the progress of which was regulated by traditional modes of life and forms of political organization. Continuing in their role as the political elites of the countryside in this new era were figures known as chihō meibōka. Having served as village leaders in the Tokugawa order, meibōka, which can be translated as ’local notables’ or ’men of local influence,’ were looked to by early Meiji leaders to ensure the maintenance of rural society in the years following the Restoration. The decades that followed saw cooperation and conflict between meibōka and government, and local notables came to occupy a distinct space in the political order as the point of contact between government and the rural public. Representing local interests, first in their interaction with bureaucratic political administrators and later with fledgling political parties, meibōka were able to organize and offer up the support of the rural public in exchange for government funds to be spent in and on their local areas. This paper will explore the nature of the interaction between meibōka, the central and prefectural governments, and the rural public in order to examine the workings of their relationships to one another. This exploration will demonstrate that these relationships resulted in a system in which narrow local interests became the sole subject of dialogue between the public and those who represented them in government, and in which political ideology played a role of negligible importance.
