Validation of a new method to assess the long-term Hypothalamic-Pituitary-Adrenal Activity using hair glucocorticoids as biomarkers. - Studies on pigs and laboratory Sprague-Dawley Rats

description: The evaluation of chronic activity of the hypothalamic-pituitary-adrenal (HPA) axis is critical for determining the impact of chronic stressful situations. The potential use of hair glucocorticoids as a non-invasive, retrospective, biomarker of long term HPA activity is of great interest, and it is gaining acceptance in humans and animals. However, there are still no studies in literature examining hair cortisol concentration in pigs and corticosterone concentration in laboratory rodents. Therefore, we developed and validated, for the first time, a method for measuring hair glucocorticoids concentration in commercial sows and in Sprague-Dawley rats. Our preliminary data demonstrated: 1) a validated and specific washing protocol and extraction assay method with a good sensitivity in both species; 2) the effect of the reproductive phase, housing conditions and seasonality on hair cortisol concentration in sows; 3) similar hair corticosterone concentration in male and female rats; 4) elevated hair corticosterone concentration in response to chronic stress manipulations and chronic ACTH administration, demonstrating that hair provides a good direct index of HPA activity over long periods than other indirect parameters, such adrenal or thymus weight. From these results we believe that this new non-invasive tool needs to be applied to better characterize the overall impact in livestock animals and in laboratory rodents of chronic stressful situations that negatively affect animals welfare. Nevertheless, further studies are needed to improve this methodology and maybe to develop animal models for chronic stress of high interest and translational value in human medicine.

Cell death mechanisms triggered by monoclonal antibodies against CD99 in Ewing sarcoma: Cross-talk between MDM2, IGF-1R and Ras/MAPK

description: CD99 is a 32 kDa transmembrane protein whose high expression characterizes Ewing sarcoma (ES), a very aggressive pediatric bone tumor. In addition to its diagnostic value, CD99 has therapeutic potential since it leads to rapid and massive ES cell death when engaged with specific antibodies. Here a novel mechanism of cell death triggered via CD99 is shown, leading, ultimately, to the appearance of macropinocytotic vescicles. Anti-CD99 mAb 0662 induces MDM2 ubiquitination and degradation, which causes not only a p53 reactivation but also the IGF-1R induction and its subsequent internalization; CD99 results internalized together with IGF-1R inside endosomes, but then the two molecules display a different sorting: CD99 is degraded, while IGF-1R is recycled on the surface, causing, as a final step, the up-regulation of RAS-MAPK. High-expressing CD99 mesenchymal stem cells show mild Ras induction but no p53 activation and escape cell death, but in presence of EWS/FLI1 mesenchymal stem cells expressing CD99 show a stronger Ras induction and a p53 reactivation, leading to a significant cell death rate. We propose that CD99 triggering in a EWS/FLI1-driven oncogenetic context creates a synergy between RAS upregulation and p53 activation in ES cells, leading to cell death. Moreover, our data rule out possible concerns on toxicity related to the broad CD99 expression in normal tissues and provide the rationale for the therapeutic use of anti-CD99 MAbs in the clinic.

description: We study the spin dynamics of a long nanomagnet driven by an electrical current. In the case of only DC current, the spin dynamics has a sophisticated bifurcation diagram of attractors. One type of attractors is a weak chaos. On the other hand, in the case of only AC current, the spin dynamics has a rather simple bifurcation diagram of attractors. That is, for small Gilbert damping, when the AC current is below a critical value, the attractor is a limit cycle; above the critical value, the attractor is chaotic (turbulent). For normal Gilbert damping, the attractor is always a limit cycle in the physically interesting range of the AC current. We also developed a Melnikov integral theory for a theoretical prediction on the occurrence of chaos. Our Melnikov prediction seems performing quite well in the DC case. In the AC case, our Melnikov prediction seems predicting transient chaos. The sustained chaotic attractor seems to have extra support from parametric resonance leading to a turbulent state.

description: In this paper, we consider a simplified model of turbulence for large Reynolds numbers driven by a constant power energy input on large scales. In the statistical stationary regime, the behaviour of the kinetic energy is characterised by two well defined phases: a laminar phase where the kinetic energy grows linearly for a (random) time $t_w$ followed by abrupt avalanche-like energy drops of sizes $S$ due to strong intermittent fluctuations of energy dissipation. We study the probability distribution $P[t_w]$ and $P[S]$ which both exhibit a quite well defined scaling behaviour. Although $t_w$ and $S$ are not statistically correlated, we suggest and numerically checked that their scaling properties are related based on a simple, but non trivial, scaling argument. We propose that the same approach can be used for other systems showing avalanche-like behaviour such as amorphous solids and seismic events.

description: This paper aims to improve the reliability of optimal control using models constructed by machine learning methods. Optimal control problems based on such models are generally non-convex and difficult to solve online. In this paper, we propose a model that combines the Hammerstein-Wiener model with input convex neural networks, which have recently been proposed in the field of machine learning. An important feature of the proposed model is that resulting optimal control problems are effectively solvable exploiting their convexity and partial linearity while retaining flexible modeling ability. The practical usefulness of the method is examined through its application to the modeling and control of an engine airpath system.

description: We present a general prescription for the holographic computation of real-time n-point functions in non-trivial states. In QFT such real-time computations involve a choice of a time contour in the complex time plane. The holographic prescription amounts to ``filling in'' this contour with bulk solutions: real segments of the contour are filled in with Lorentzian solutions while imaginary segments are filled in with Riemannian solutions and appropriate matching conditions are imposed at the corners of the contour. We illustrate the general discussion by computing the 2-point function of a scalar operator using this prescription and by showing that this leads to an unambiguous answer with the correct i epsilon insertions.

description: This paper investigates a new experimental framework to test the braneworld hypothesis. Recent theoretical results have shown the possibility of matter exchange between branes under the influence of suitable magnetic vector potentials. It is shown that the required conditions might be achieved with present-day technology. The experiment uses a source of pulsed and coherent electromagnetic radiation and relies on the Hansch frequency comb technique well-known in ultrahigh-precision spectroscopy. A good matter candidate for testing the hypothesis is a polarized ultracold neutron gas for which the number of swapped neutrons is measured.

description: The prediction of surrounding traffic participants behavior is a crucial and challenging task for driver assistance and autonomous driving systems. Today's approaches mainly focus on modeling dynamic aspects of the traffic situation and try to predict traffic participants behavior based on this. In this article we take a first step towards extending this common practice by calculating location-specific a-priori lane change probabilities. The idea behind this is straight forward: The driving behavior of humans may vary in exactly the same traffic situation depending on the respective location. E.g. drivers may ask themselves: Should I pass the truck in front of me immediately or should I wait until reaching the less curvy part of my route lying only a few kilometers ahead? Although, such information is far away from allowing behavior prediction on its own, it is obvious that today's approaches will greatly benefit when incorporating such location-specific a-priori probabilities into their predictions. For example, our investigations show that highway interchanges tend to enhance driver's motivation to perform lane changes, whereas curves seem to have lane change-dampening effects. Nevertheless, the investigation of all considered local conditions shows that superposition of various effects can lead to unexpected probabilities at some locations. We thus suggest dynamically constructing and maintaining a lane change probability map based on customer fleet data in order to support onboard prediction systems with additional information. For deriving reliable lane change probabilities a broad customer fleet is the key to success.

description: To leading order approximation, the physical content of generalized parton distributions (GPDs) that is accessible in deep virtual electroproduction of photons or mesons is contained in their value on the cross-over trajectory. This trajectory separates the t-channel and s-channel dominated GPD regions. The underlying Lorentz covariance implies correspondence between these two regions through their relation to GPDs on the cross-over trajectory. This point of view leads to a family of GPD sum rules which are a quark analogue of finite energy sum rules and it guides us to a new phenomenological GPD concept. As an example, we discuss the constraints from the JLab/Hall A data on the dominant u-quark GPD H. The question arises whether GPDs are governed by some kind of holographic principle.

Signature Quantization in Fading CDMA With Limited Feedback
Creators: name: Santipach, Wiroonsak
Publisher: name: arXiv
Year: 2008
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this work, we analyze the performance of a signature quantization scheme for reverse-link Direct Sequence (DS)- Code Division Multiple Access (CDMA). Assuming perfect estimates of the channel and interference covariance, the receiver selects the signature that minimizes interference power or maximizes signal-to-interference plus noise ratio (SINR) for a desired user from a signature codebook. The codebook index corresponding to the optimal signature is then relayed to the user with a finite number of bits via a feedback channel. Here we are interested in the performance of a Random Vector Quantization (RVQ) codebook, which contains independent isotropically distributed vectors. Assuming arbitrary transmit power allocation, we consider additive white Gaussian noise (AWGN) channel first with no fading and subsequently, with multipath fading. We derive the corresponding SINR in a large system limit at the output of matched filter and linear minimum mean squared error (MMSE) receiver. Numerical examples show that the derived large system results give a good approximation to the performance of finite-size system and that the MMSE receiver achieves close to a single-user performance with only one feedback bit per signature element.

Dilepton spectra are not affected by strong interaction and can therefore probe the whole time evolution of the collision. Thus they may be sensitive to onset of deconfinement, chiral symmetry restoration, as well as the production of thermal photons. The PHENIX experiment measured the production of e+e- pairs in p+p and Au+Au collisions at sqrt(s_NN)= 200 GeV. An enhanced dilepton yield in the mass range 150

description: Lattice simulations of the QCD correlation functions in the Landau gauge have established two remarkable facts. First, the coupling constant in the gauge sector remains finite and moderate at all scales, suggesting that some kind of perturbative description should be valid down to infrared momenta. Second, the gluon propagator reaches a finite nonzero value at vanishing momentum, corresponding to a gluon screening mass. We review recent studies which aim at describing the long-distance properties of Landau gauge QCD by means of the perturbative Curci-Ferrari model. The latter is the simplest deformation of the Faddeev-Popov Lagrangian in the Landau gauge that includes a gluon screening mass at tree-level. There are, by now, strong evidences that this approach successfully describes many aspects of the infrared QCD dynamics. In particular, several correlation functions were computed at one- and two-loop orders and compared with {\it ab-initio} lattice simulations. The typical error is of the order of ten percent for a one-loop calculation and drops to few percents at two loops. We review such calculations in the quenched approximation as well as in the presence of dynamical quarks. In the latter case, the spontaneous breaking of the chiral symmetry requires to go beyond a coupling expansion but can still be described in a controlled approximation scheme in terms of small parameters. We also review applications of the approach to nonzero temperature and chemical potential.

description: In this paper, we propose a novel quantum paramagnetic state in two-dimensional antiferromagnets: the spontaneously trimer state, which is constructed by the trimers of spins. Each trimer is a singlet state formed by three neighboring spins with SU(3) symmetry. A frustrated spin-1 Heisenberg model in the kagome lattice is investigated. By analogy to the pseudo-potential approach in the fractional quantum Hall effect (FQHE), we find that the trimer state provides a perfect description for the exact ground state of this model. Other interesting properties, such as the local excitations as well as magnetization plateaus have also been investigated. It is shown that this novel state would deepen our understanding of the nature of the many-body entanglement in the two-dimensional strong correlated systems.

The system has been originated by a steady-state heat conduction problem with non-monotone multivalued subdifferential boundary condition on a portion of the boundary of the domain described by the Clarke generalized gradient of a locally Lipschitz function. We prove an existence result for the optimal controls and we show an asymptotic result for the optimal controls and the system states, when the parameter, like a heat transfer coefficient, tends to infinity on a portion of the boundary.

description: We study the properties of Tsallis entropy and Shannon entropy from the point of view of algorithmic randomness. In algorithmic information theory, there are two equivalent ways to define the program-size complexity K(s) of a given finite binary string s. In the standard way, K(s) is defined as the length of the shortest input string for the universal self-delimiting Turing machine to output s. In the other way, the so-called universal probability m is introduced first, and then K(s) is defined as -log_2 m(s) without reference to the concept of program-size. In this paper, we investigate the properties of the Shannon entropy, the power sum, and the Tsallis entropy of a universal probability by means of the notion of program-size complexity. We determine the convergence or divergence of each of these three quantities, and evaluate its degree of randomness if it converges.

description: Resumo A variação pluviométrica na região equatorial do planeta é classicamente atribuída às flutuações latitudinais do cinturão de chuva tropical, a Zona de Convergência Intertropical (ZCIT). Novas evidências demonstram que essas variações também foram causadas pela contração/expansão desse cinturão, forçadas por mudanças na temperatura da superfície do mar e na circulação atmosférica. A porção norte do Nordeste do Brasil recebe precipitação de março a maio quando a ZCIT apresenta o seu posicionamento mais a sul, afetando o Rio Grande do Norte (RN). Nesses meses, a maior atividade convectiva da ZCIT confere valores mais empobrecidos de d18O nas águas das chuvas devido ao efeito de quantidade. A partir dos dados de d18O, indicadores de chuva local, obtidos em estalagmites das cavernas do Trapiá e Furna Nova (RN), datados pelo método U/Th, a variação de precipitação de ZCIT foi reconstituída para os últimos 2.000 anos. A curva composta a partir dos dados de d18O possuem resultados de ~ 0‰. Secas mais intensas são registradas entre 250-550 CE e 1070-1570 CE, com valores d18O de ~ 1,10‰ e ~ 0,83‰, respectivamente. Outros dois intervalos exibem fases mais úmidas, com valores de ~ -0,08‰ durante a Anomalia Climática Medieval (ACM) (850-1050 CE) e de ~ -0,86‰ durante a Pequena Idade do Gelo (PIG) (1570-1850 anos CE). O cinturão de nuvens tropicais esteve expandido durante o ACM, aumentando a umidade na Bacia de Cariaco, no leste da Amazônia e no RN, enquanto resultados das áreas de monções registram secas. O aquecimento do Atlântico Tropical pode gerar expansão da ZCIT, assim como perturbar o gradiente térmico entre o mar e a terra, afetando a dinâmica da pressão atmosférica e reduzindo o transporte de vapor em direção ao continente, enfraquecendo a monção. Durante a PIG os registros indicam maior deslocamento para sul da ZCIT e reduzida projeção continental sobre o leste da Amazônia, possivelmente associada ao deslocamento para noroeste do eixo de umidade que adentra na Amazônia, que intensificou a monção na maior parte da América do Sul (AS) durante a PIG. Esses resultados sugerem que durante o último milênio, o cinturão tropical não variou de forma uniforme sobre a AS e sua dinâmica influenciou a intensidade e o posicionamento das monções na AS.

description: Resumo Com o avanço da tecnologia, motivado pela crescente demanda por bens de consumo, novas substâncias são produzidas. Estas possuem em sua formulação produtos químicos orgânicos e inorgânicos com o objetivo de melhorar ou aumentar algumas de suas propriedades, tornando-as mais atraentes para o consumidor. Dentre essas novas substâncias, pode-se incluir os denominados Contaminantes Emergentes (CE), que são definidos como substâncias químicas naturais ou sintéticas que não são devidamente caracterizadas, mas que são capazes de surgir no ambiente e provocar efeitos adversos, conhecidos ou não, sobre ecossistemas ou sobre a saúde humana. Destacam-se como CE as substâncias Per e Poli-Fluoralquiladas (PFAS), que são substâncias alifáticas orgânicas e inorgânicas caracterizadas por terem uma cadeia alquílica total (per) ou parcial (poli) fluorada. Isso faz com que tenham uma variação nas propriedades físicas e químicas, além da presença de um grupo funcional terminal, como por exemplo, carboxilatos, sulfonatos, sulfonamida, fosfato e álcoois. Devido à forte ligação existente entre o Flúor e o Carbono, essas substâncias não são facilmente degradadas por mecanismos físicos e químicos quando entram no meio ambiente, além de ter uma conhecida toxicidade para o ser humano, conforme estudos realizados por agências reguladoras estrangeiras. Dessa forma, destaca-se a importância de realizar um estudo detalhado da distribuição dos PFAS, especificamente em água subterrânea, considerando a problemática do abastecimento público, e a questão de áreas contaminadas, para o cenário nacional (Brasil). Devido às características de toxicidade dos CE, este projeto propõe realizar a caracterização dessa contaminação, considerando a água subterrânea (aquífero freático). Os resultados poderão demonstrar como estão distribuídos nessa matriz associada a fonte, principalmente de efluente doméstico, a fim de que se possa no futuro, propor um sistema de gerenciamento de áreas contaminadas para a mitigação dos efeitos adversos que essas substâncias possam causar à saúde humana e à biota. Para isso, serão avaliadas as concentrações e o perfil da distribuição dos PFAS em água subterrânea contaminada com efluente doméstico proveniente de vazamentos, gerando assim uma base de dados para o monitoramento futuro dos PFAS.

description: I propose –very schematically– an unavoidable task: to continue unmasking a contemporary expression so harmful to man and nature as the so-called neoliberalism. For this reason, I will use the same statements that our honoree has been making on the subject, but not before synthesizing some common thematic places. Among the slogans and phrases that have emerged from the discursive neoliberal power plant and have penetrated deep into the population are those that advocate that the State is not the solution but the problem or more affirmatively and conclusively that the State is the problem and the markets the solution. Likewise, we synthesize our perspective on the matter, which in part consists of proposing a nominal transmutation: to replace the term neoliberalism with the expression neuroliberalism

description: Elbow fractures are one of the most common fracture types. Diagnoses on elbow fractures often need the help of radiographic imaging to be read and analyzed by a specialized radiologist with years of training. Thanks to the recent advances of deep learning, a model that can classify and detect different types of bone fractures needs only hours of training and has shown promising results. However, most existing deep learning models are purely data-driven, lacking incorporation of known domain knowledge from human experts. In this work, we propose a novel deep learning method to diagnose elbow fracture from elbow X-ray images by integrating domain-specific medical knowledge into a curriculum learning framework. In our method, the training data are permutated by sampling without replacement at the beginning of each training epoch. The sampling probability of each training sample is guided by a scoring criterion constructed based on clinically known knowledge from human experts, where the scoring indicates the diagnosis difficultness of different elbow fracture subtypes. We also propose an algorithm that updates the sampling probabilities at each epoch, which is applicable to other sampling-based curriculum learning frameworks. We design an experiment with 1865 elbow X-ray images for a fracture/normal binary classification task and compare our proposed method to a baseline method and a previous method using multiple metrics. Our results show that the proposed method achieves the highest classification performance. Also, our proposed probability update algorithm boosts the performance of the previous method.

description: We present a method for the photometric selection of candidate quasars in multiband surveys. The method makes use of a priori knowledge derived from a subsample of spectroscopic confirmed QSOs to map the parameter space. The disentanglement of QSOs candidates and stars is performed in the colour space through the combined use of two algorithms, the Probabilistic Principal Surfaces and the Negative Entropy clustering, which are for the first time used in an astronomical context. Both methods have been implemented in the VONeural package on the Astrogrid VO platform. Even though they belong to the class of the unsupervised clustering tools, the performances of the method are optimized by using the available sample of confirmed quasars and it is therefore possible to learn from any improvement in the available "base of knowledge". The method has been applied and tested on both optical and optical plus near infrared data extracted from the visible SDSS and infrared UKIDSS-LAS public databases. In all cases, the experiments lead to high values of both efficiency and completeness, comparable if not better than the methods already known in the literature. A catalogue of optical candidate QSOs extracted from the SDSS DR7 Legacy photometric dataset has been produced and is publicly available at the URL voneural.na.infn.it/qso.html.

description: We establish a correspondence (or duality) between the characters and the crystal bases of finite-dimensional representations of quantum groups associated to Langlands dual semi-simple Lie algebras. This duality may also be stated purely in terms of semi-simple Lie algebras. To explain this duality, we introduce an "interpolating quantum group" depending on two parameters which interpolates between a quantum group and its Langlands dual. We construct examples of its representations, depending on two parameters, which interpolate between representations of two Langlands dual quantum groups.

description: Resumo O Brasil tradicionalmente ocupa uma posição de destaque na produção mundial de ouro, predominantemente realizada por mineradoras e secundariamente por mineração artesanal e garimpos. Quando executado sem planejamento, ou de modo ilegal, o garimpo causa impactos socioambientais e degradação. Na região Amazônica esse panorama é favorecido pelas amplas áreas de floresta com baixa densidade demográfica, dificultando a fiscalização de atividade predatória e potencializando atividades ilegais. O rastreamento de ouro proveniente de mineração artesanal ilegal tem sido um desafio para autoridades brasileiras e internacionais e a aplicação de geoquímica isotópica como um traçador tem se mostrado uma tecnologia eficiente para identificação de diversas fontes e tipos de materiais. Desse modo, a premissa deste trabalho é a identificação da assinatura isotópica de Pb como uma ferramenta forense para rastreabilidade de ouro proveniente da região Amazônica, mais especificamente, no norte do estado do Amapá. Nessa região, as mineralizações auríferas se inserem no contexto geológico do Domínio Lourenço, com depósitos tanto do tipo orogênico quanto veios mineralizados associados a intrusões graníticas. As mineralizações ocorrem associadas a sulfetos como pirita, calcopirita, arsenopirita e pirrotita. Trabalhos recentes têm testado a variação isotópica do Pb em ouro em processos industriais e naturais de formação do minério, as quais dependerão das diferentes fontes de magma, fluidos e metais presentes no sistema, sendo um traçador promissor para ouro. O ouro primário e aluvionar (in-natura) pode apresentar composição isotópica distinta do ouro processado e purificado pela mineração artesanal e, portanto, será necessário avaliar a influência do processo de beneficiamento em amostras processadas. A mudança da assinatura isotópica induzida pelo processo de purificação e beneficiamento antrópico será quantificada, bem como a identificação das fontes naturais será feita através de estudos petrográficos, geoquímicos e isotópicos. Desse modo, espera-se entender como a composição isotópica de Pb varia na cadeia de beneficiamento do ouro e o quanto é possível traçar de sua origem e correlacioná-lo a depósitos de ouro específicos. O desenvolvimento de um banco de dados que possa ser utilizado pelas autoridades brasileiras (Polícia Federal e órgãos ambientais) irá auxiliar no combate à mineração ilegal na Amazônia, podendo também ser expandida para países fronteiriços na América do Sul.
Kultur der Digitalität = Kultur der Partizipation?

description: Der Beitrag rückt das Zusammenspiel von Medien-, Demokratie- und Kultureller Bildung (Autenrieth et al. 2020) in den Fokus. Thematisiert werden u.a. der Einsatz digitaler Techniken in der Schule sowie die partizipativ-interdisziplinäre Entwicklung von Schule und Unterricht im Kontext gesamtgesellschaftlicher Transformationsprozesse. Theoretische Rahmung bilden Annahmen darüber, dass es beim Einsatz von digitalen Medien in der Schule um ein Lernen mit und über Medien geht, damit sich Schülerinnen und Schüler selbstbestimmt und kritisch-reflexiv in ihren vielfältig geprägten Lebenswelten bewegen, sich selbständig Urteile bilden und ihre kulturell-politische Identität sowie Umwelt eigenständig erschließen können. Im Zentrum einer an demokratischen Werten orientierten Schul- und Unterrichtsentwicklung steht das handelnde Subjekt und seine sozialen Praktiken im Sinne einer Verschränkung von Subjekt und Struktur nach Anthony Giddens (1988). Bei der Thematisierung des Einsatzes von digitalen Medien in Schulen geht es um das partizipative Entwickeln von didaktischen Konzepten und Gestalten von Handlungsmöglichkeiten und -räumen. Ferner geht es um eine Analyse gesellschaftlicher Prozesse und eigener Weltanschauungen, da die digital vernetzte Welt und die daraus resultierenden Phänomene Teil des Metaprozesses Digitalisierung sind (Krotz 2007: 11). Digitalisierung ist ein Produkt der menschlichen Kultur (Rat für Kulturelle Bildung 2019) und hat Auswirkungen darauf, wie Menschen leben, welche Wahrnehmungsstrukturen sie ausbilden und nutzen und wie sie ihre Umwelt gestalten. Unterrichtsentwicklung stellt dabei eine ko-konstruktive, partizipativ organisierte Gestaltungsaufgabe dar, um etwas Neues in bestehende Strukturen einzubringen und diese zu verändern – insbesondere mit Blick auf den Einsatz digitaler Medien in der Schule (Irion 2018, 2016; Döbeli Honegger 2016).

description: We measure the gravitational recoil for unequal-mass-black- hole-binary mergers, with the larger BH having spin a/m^H=0.8, and the smaller BH non-spinning. We choose our configurations such that, initially, the spins lie on the orbital plane. The spin and orbital plane precess significantly, and we find that the out-of plane recoil (i.e. the recoil perpendicular to the orbital plane around merger) varies as η^2 / (1+q), in agreement with our previous prediction, based on the post-Newtonian scaling.
