description: We study model-free learning methods for the output-feedback Linear Quadratic (LQ) control problem in finite-horizon subject to subspace constraints on the control policy. Subspace constraints naturally arise in the field of distributed control and present a significant challenge in the sense that standard model-based optimization and learning leads to intractable numerical programs in general. Building upon recent results in zeroth-order optimization, we establish model-free sample-complexity bounds for the class of distributed LQ problems where a local gradient dominance constant exists on any sublevel set of the cost function. %which admit a local gradient dominance constant valid on the sublevel set of the cost function. We prove that a fundamental class of distributed control problems - commonly referred to as Quadratically Invariant (QI) problems - as well as others possess this property. To the best of our knowledge, our result is the first sample-complexity bound guarantee on learning globally optimal distributed output-feedback control policies.

description: In human uveal melanoma (UM), tumor enlargement is associated with increases in aqueous humor vascular endothelial growth factor-A (VEGF-A) content that induce neovascularization. 3-Iodothyronamine (3-T1AM), an endogenous thyroid hormone metabolite, activates TRP melastatin 8 (TRPM8), which blunts TRP vanilloid 1 (TRPV1) activation by capsaicin (CAP) in human corneal, conjunctival epithelial cells, and stromal cells. We compare here the effects of TRPM8 activation on VEGF-induced transactivation of TRPV1 in an UM cell line (92.1) with those in normal primary porcine melanocytes (PM) since TRPM8 is upregulated in melanoma. Fluorescence Ca2+-imaging and planar patch-clamping characterized functional channel activities. CAP (20 μM) induced Ca2+ transients and increased whole-cell currents in both the UM cell line and PM whereas TRPM8 agonists, 100 μM menthol and 20 μM icilin, blunted such responses in the UM cells. VEGF (10 ng/ml) elicited Ca2+ transients and augmented whole-cell currents, which were blocked by capsazepine (CPZ; 20 μM) but not by a highly selective TRPM8 blocker, AMTB (20 μM). The VEGF-induced current increases were not augmented by CAP. Both 3-T1AM (1 μM) and menthol (100 μM) increased the whole-cell currents, whereas 20 μM AMTB blocked them. 3-T1AM exposure suppressed both VEGF-induced Ca2+ transients and increases in underlying whole-cell currents. Taken together, functional TRPM8 upregulation in UM 92.1 cells suggests that TRPM8 is a potential drug target for suppressing VEGF induced increases in neovascularization and UM tumor growth since TRPM8 activation blocked VEGF transactivation of TRPV1.

description: Il concetto arendtiano di “banalità del male” risulta ancora la categoria filosofica più efficace per indagare sul male totalitario e su alcuni aspetti della mente umana. Questo saggio ne ripercorre la genesi, tentando di scoprire i meccanismi all’origine della corruzione del pensiero e della sua metamorfosi a partire dal potere reificante della forza del terrore. Relativamente a ciò, la figura di Eichmann offre un esempio paradigmatico di dissociazione morale dalla realtà, dagli/dalle altri/e, da se stessi/e. The arendtian concept of the “banality of evil” appears to be the most effective philosophical notion for an examination of the evil of totalitarianism and some aspects of human mind. This essay will revisit the source of it, endeavoring to discover the mechanisms at the origins of the corruption of the thought and of its metamorphosis starting from the deifying power of terror. In this connection, Eichmann offers a paradigmatic example of moral dissociation from reality, from the others and from oneself.

description: We report the discovery of a galaxy overdensity around a Compton-thick Fanaroff-Riley type II (FRII) radio galaxy at z=1.7 in the deep multiband survey around the z=6.3 QSO SDSS J1030+0524. Based on a 6hr VLT/MUSE and on a 4hr LBT/LUCI observation, we identify at least eight galaxy members in this structure with spectroscopic redshift z=1.687-1.699, including the FRII galaxy at z=1.699. Most of the identified overdensity members are blue, compact galaxies that are actively forming stars at rates of $\sim$8-60 $M_{\odot}$ yr$^{-1}$. Based on a 500ks Chandra ACIS-I observation we found that the FRII nucleus hosts a luminous QSO ($L_{2-10keV}=1.3\times10^{44}$ erg s$^{-1}$, intrinsic and rest-frame) that is obscured by Compton-thick absorption ($N_H=1.5\pm0.6\times 10^{24}$ cm$^{-2}$). Our Chandra observation, the deepest so far for a distant FRII within a galaxy overdensity, revealed significant diffuse X-ray emission within the region covered by the overdensity. In particular, X-ray emission extending for $\sim$240 kpc is found around the Eastern lobe of the FRII. Four out of the six MUSE star forming galaxies in the overdensity are distributed in an arc-like shape at the edge of this diffuse X-ray emission. The probability of observing by chance four out of the six $z=1.7$ sources at the edge of the diffuse emission is negligible. In addition, these four galaxies have the highest specific star formation rates of the MUSE galaxies in the overdensity and lie above the main sequence of field galaxies of equal stellar mass at z=1.7. We propose that the diffuse X-rays originate from an expanding bubble of gas that is shock-heated by the FRII jet, and that star formation is promoted by the compression of the cold interstellar medium of the galaxies around the bubble, which may be remarkable evidence of positive AGN feedback on cosmological scales.

description: Background: In Vietnam, the mental health care infrastructure is on the verge of transformation with an increase in the demand for access to adequate and effective mental health care services. Public attitudes towards mental illness, as well as corresponding treatment options influence help-seeking behaviors of patients and caregivers, affecting the course of their treatment. This study assesses attitudes towards treatment options for depression and schizophrenia, as the two most common psychiatric disorders in Vietnam, accounting for at least 75% of all psychiatric inpatients. Methods: A general population-based survey was conducted in Hanoi, Vietnam between April and August 2013. Participants received a description of a person with symptoms of either depression (n=326) or schizophrenia (n=403) and were asked to give recommendations for adequate sources of mental health support and treatment options. Multiple analyses on a single item level compared the likelihood of recommendation between schizophrenia and depression. Results: Overall, respondents recommended health care services, ranging from seeking mental health care professionals, psychotherapists, and psychiatrists for both disorders. Psychotherapy was the most favored treatment method, whereas further treatment options, such as concentration and relaxation exercises, meditation or yoga and psychotropic medication were also endorsed as helpful. For the schizophrenia vignette condition, psychotherapy, visiting a psychiatrist or psychotherapist received stronger endorsement rates as compared to the depression vignette. Furthermore, ECT, Feng Shui-based practices, praying and visiting natural healers were recommended less by respondents for the depression vignette in comparison with the schizophrenia vignette. Conclusions: The Vietnamese public endorsed evidence-based treatment recommendations from a variety of treatments options. Differences in the treatment recommendations between depression and schizophrenia reflected the perceived severity of each disorder. Further developments of the Vietnamese mental health care system concerning mental health care providers, as well as the legal regulations surrounding the provision of psychotherapy are needed.

The angular distributions show not only the usual diffraction pattern but also, at larger angles, intermediate structure of refractive origin on which finer oscillations are superimposed. The large angle features can be consistently described including explicitly the elastic $α$-transfer process and using a refractive optical potential with a deep real part and a weakly absorptive imaginary part.

description: We discuss the reduction of the open membrane metric and determine the (previously unknown) conformal factor. We also construct SL(2,R) invariant open string metrics and complex open string coupling constants by reducing the open membrane metric on a 2-torus. In doing so we also clarify some issues on manifest SL(2,R) symmetry of the D3-brane. We remark on the consequences of our results for the recently conjectured existence of decoupled (p,q) non-commutative open string theories in type IIB string theory.

description: We develop a stochastic model to rank different policies (tax, fixed cap and relative cap) according to their expected total social costs. Three types of uncertainties are taken into account: uncertainty about abatement costs, business-as-usual (BAU) emissions and future economic output (the two latter being correlated). Two parameters: the ratio of slopes of marginal benefits and marginal costs, and the above-mentioned correlation, are crucial to determine which instrument is preferred. When marginal benefits are relatively flatter than marginal costs, prices are preferred over fixed caps (Weitzman’s result). When the former correlation is higher than a parameter- dependent threshold, relative caps are preferred to fixed caps. An intermediate condition is found to compare the tax instrument and the relative cap. The model is then empirically tested for seven different regions (China, the United States, Europe, India, Russia, Brazil and Japan). We find that tax is preferred to caps (absolute or relative) in all cases, and that relative caps are preferred to fixed caps in the US and emerging countries (except Brazil where it is ambiguous), whereas fixed cap are preferred to relative cap in Europe and Japan.

description: L’analisi di alcune prospettive femministe sulla maternità, in questo saggio, ha l’obiettivo di decostruire la visione naturalistica e innatista dell’istinto (amore) e della pratica materni affinché si spezzi il legame, instaurato dal patriarcato, che concilia femminilità e maternità, lasciando spazio, da un lato, alla possibilità di scelta, desiderio e conflitto nella costruzione di una identità femminile affrancata dal simbolico materno, e dall’altro ad una necessaria rivoluzione che conduca ad una genitorialità condivisa e non inchiodata da costrutti e stereotipi culturali. The analysis of some feminist perspectives about maternity, in this essay, has the aim of deconstructing the naturalistic and innatistic vision of maternal instinct (love) and practice so that the bond, established by patriarchy, which reconciles femininity and motherhood is broken , leaving space, on the one hand, for the possibility of choice, desire and conflict in the construction of the female identity freed from the maternal symbol, and on the other, a necessary revolution that leads to a shared parenting and not nailed by cultural constructs and stereotypes.

description: The paper outlines the most noticeable economic effects of the 2004 accession of Slovenia to the European Union (EU) on its agri-food sector. The main national statistical data are used to compare the situation in the Slovenian agri-food sector in the pre- and postaccession period. The main expected effects were related to joining the vast Common market through increased market competition and opportunities, as well as through the structural and organizational adjustments of a relatively small agri-food sector to it. Unexpectedly, these adjustments were halted in general, resulting most evidently in the increased export of raw agri-food products and import of processed products. Slovenian agri-food chain, especially the food industry, remains heavily challenged by its relatively poor competitive and organizational performance, both even more pronounced a decade after the EU accession.

description: Background: The onset and progression of osteoarthritis, but also the wear and loosening of the components of an artificial joint, are commonly associated with mechanical overloading of the structures. Knowledge of the mechanical forces acting at the joints, together with an understanding of the key factors that can alter them, are critical to develop effective treatments for restoring joint function. While static anatomy is usually the clinical focus, less is known about the impact of dynamic factors, such as individual muscle recruitment, on joint contact forces. Methods: In this study, instrumented knee implants provided accurate in vivo tibio-femoral contact forces in a unique cohort of 9 patients, which were used as input for subject specific musculoskeletal models, to quantify the individual muscle forces during walking and stair negotiation. Results: Even between patients with a very similar self-selected gait speed, the total tibio-femoral peak forces varied 1.7-fold, but had only weak correlation with static alignment (varus/valgus). In some patients, muscle co-contraction of quadriceps and gastrocnemii during walking added up to 1 bodyweight (~50%) to the peak tibio-femoral contact force during late stance. The greatest impact of co-contraction was observed in the late stance phase of stair ascent, with an increase of the peak tibio-femoral contact force by up to 1.7 bodyweight (66%). Conclusions: Treatment of diseased and failed joints should therefore not only be restricted to anatomical reconstruction of static limb axes alignment. The dynamic activation of muscles, as a key modifier of lower limb biomechanics, should also be taken into account and thus also represents a promising target for restoring function, patient mobility, and preventing future joint failure.

description: Polyhedral vesicles with a large bending modulus of the membrane such as the gel phase lipid membrane were studied using a Brownian dynamics simulation. The vesicles exhibit various polyhedral morphologies such as tetrahedron and cube shapes. We clarified two types of line defects on the edges of the polyhedrons: cracks of both monolayers at the spontaneous curvature of monolayer $C_{\text {0}}<0$, and a crack of the inner monolayer at $C_{\text {0}}\ge0$. Around the latter defect, the inner monolayer curves positively. Our results suggested that the polyhedral morphology is controlled by $C_{\text {0}}$.

description: We revisit the multi-loop structure of the anomalous-dimension matrix governing the infrared divergences of massless $n$-particle scattering amplitudes in non-abelian gauge theories. In particular, we derive its most general form at four-loop order, significantly simplifying corresponding expressions given previously. By carefully reevaluating the constraints imposed by two-particle collinear limits, we find that at four-loop order color structures involving $d_R^{abcd}$, the symmetrized trace of four group generators, appear along with cusp logarithms $\ln[μ^2/(-s_{ij})]$. As a consequence, naive Casimir scaling of the cusp anomalous dimensions associated with the quark and gluon form factors is violated, while a generalized form of Casimir scaling still holds. Our results provide an important ingredient for resummations of large logarithms in $n$-jet cross sections with next-to-next-to-next-to leading logarithmic (N$^3$LL) accuracy.

This study estimated that the impact that hunting pressure, beef prices, and lagged land values had on county-level pasture values in North Dakota. Using panel data from 1989-2006, a fixed effects model was specified and estimated. Results showed that on average, hunting pressure increased pasture land values by $16.27 per acre or about nine percent of total pasture value.

description: The problem of defining and constructing representations of the Canonical Commutation Relations can be systematically approached via the technique of {\it algebraic quantization}. In particular, when the phase space of the system is linear and finite dimensional, the `vertical polarization' provides an unambiguous quantization. For infinite dimensional field theory systems, where the Stone-von Neumann theorem fails to be valid, even the simplest representation, the Schroedinger functional picture has some non-trivial subtleties. In this letter we consider the quantization of a real free scalar field --where the Fock quantization is well understood-- on an arbitrary background and show that the representation coming from the most natural application of the algebraic quantization approach is not, in general, unitary equivalent to the corresponding Schroedinger-Fock quantization. We comment on the possible implications of this result for field quantization.

description: We investigate the effect of strange quark degrees of freedom on the formation of inhomogeneous chiral condensates in a three-flavor Nambu--Jona-Lasinio model in mean-field approximation. A Ginzburg-Landau study complemented by a stability analysis allow us to determine in a general way the location of the critical and Lifshitz points, together with the phase boundary where the (partially) chirally restored phase becomes unstable against developing inhomogeneities, without resorting to specific assumptions on the shape of the chiral condensate. We discuss the resulting phase structure and study the influence of the bare strange-quark mass $m_s$ and the axial anomaly on the size and location of the inhomogeneous phase compared to the first-order transition associated with homogeneous matter. We find that, as a consequence of the axial anomaly, critical and Lifshitz point split. For realistic strange-quark masses the effect is however very small and becomes sizeable only for small values of $m_s$.

description: The gluten-free diet is the only effective treatment available for celiac disease. However, it is difficult to adhere to and a closer look on the diet's implementation and indications reveals several ambiguities: Not only is there controversy on the threshold of gluten that can be tolerated in the frame of a strict gluten-free diet, but it is also unclear whether the gluten-free diet is an appropriate treatment in patient subgroups with asymptomatic or potential celiac disease. Reports from a number of research groups suggest that a certain proportion of patients may effectively develop tolerance to gluten and thus become suitable for gluten reintroduction over time. In this review, we set out to create an overview about the current state of research as regards the definition of a strict gluten-free diet in terms of the gluten thresholds considered tolerable and the indication for a gluten-free diet in the absence of histological abnormalities or symptoms. Furthermore, we discuss the concept that a gluten-free diet must be followed for life by all patients.

description: The discrete formulation of adiabatic quantum computing is compared with other search methods, classical and quantum, for random satisfiability (SAT) problems. With the number of steps growing only as the cube of the number of variables, the adiabatic method gives solution probabilities close to 1 for problem sizes feasible to evaluate via simulation on current computers. However, for these sizes the minimum energy gaps of most instances are fairly large, so the good performance scaling seen for small problems may not reflect asymptotic behavior where costs are dominated by tiny gaps. Moreover, the resulting search costs are much higher than for other methods. Variants of the quantum algorithm that do not match the adiabatic limit give lower costs, on average, and slower growth than the conventional GSAT heuristic method.

description: Sor Juana Inés de la Cruz es sin duda la autora mexicana más conocida de la época colonial y de la historia de la literatura novohispana. Con el término novohispano queda claro que estamos determinando un marco temporal y geográfico, además de político, creando un interesante acercamiento entre un tipo de producción artística y relativa connotación estilística, y una situación histórica. Por consiguiente, esta cercanía entre una dimensión artística y una situación histórica ha transformado la producción literaria barroca en el principal vehículo de informaciones y testimonios acerca de la cotidianidad de la vida en el siglo XVII en México. En este obscuro cruce entre creación y tradición se colocan las reflexiones sobre autobiografía y experiencia culinaria en la obra de sor Juana Inés de la Cruz que se encuentran en este ensayo. Sor Juana Inés de la Cruz is doubtlessly the most known Novohispano author. The term “novohispano” is a reference not only to a temporal, political, or geographical space, but also a particular historical situation that generated its own specific literature and artistic production that articulated independently from the European guidelines its own baroque style. As a consequence, this intersection created by the artistic dimension crossing the historical situation transformed the literary production into the main medium to receive information and testimonies about colonial daily life in the Mexican XVII century. In the space of this complex and obscure intersection between creation and tradition, it is possible to find the contribution offered in this essay about autobiography and culinary experience in sor Juana Inés de la Cruz’ writings.

description: Nicotinamide adenine dinucleotide (NAD), a prominent member of the pyridine nucleotide family, plays a pivotal role in cell-oxidation protection, DNA repair, cell signalling and central metabolic pathways, such as beta oxidation, glycolysis and the citric acid cycle. In particular, extracellular NAD(+) has recently been demonstrated to moderate pathogenesis of multiple systemic diseases as well as aging. Herein we present an assaying method, that serves to quantify extracellular NAD(+) in human heparinised plasma and exhibits a sensitivity ranging from the low micromolar into the low nanomolar domain. The assay achieves the quantification of extracellular NAD(+) by means of a two-step enzymatic cycling reaction, based on alcohol dehydrogenase. An albumin modified revised simulated body fluid was employed as standard matrix in order to optimise enzymatic activity and enhance the linear behaviour and sensitivity of the method. In addition, we evaluated assay linearity, reproducibility and confirmed long-term storage stability of extracellular NAD(+) in frozen human heparinised plasma. In summary, our findings pose a novel standardised method suitable for high throughput screenings of extracellular NAD(+) levels in human heparinised plasma, paving the way for new clinical discovery studies.
Results from FOPI on strangeness production and propagation at SIS energies

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Heavy ion collisions at SIS energies (1-2 AGeV) offer an unique tool to probe the properties of hot and dense nuclear matter. In particular, the partial restoration of chiral symmetry is predicted to lead in this energy range to in-medium modifications of hadron properties. Strange particle production below or close to the threshold energy is a useful probe to investigate these in-medium effects. The FOPI collaboration has recently measured the production and the propagation of charged and neutral strange particles. The K+ production probability is investigated as a function of the system size at a beam energy of 1.5 AGeV. Results on K0 production in Ru+Ru collisions at 1.69 AGeV are presented, as well as K-/K+ ratio as a function of rapidity. In addition, the sideward flow of charged and neutral strange particles has been measured. Results are compared to predictions of transport calculations (BUU and IQMD).

description: We report the synthesis and characterization of a rare-earth dichalcogenide EuTe$_2$. An antiferromagnetic transition was found at T$_M$ = 11 K. The antiferromagnetic order can be tuned by an applied magnetic field to access a first-order spin flop transition and a spin flip transition. These transitions are associated with a giant negative magnetoresistance with a value of nearly 100\%. Heat capacity measurements reveal strong electronic correlations and a reduced magnetic entropy. Furthermore, density functional theory calculations demonstrate that the electrons near the Fermi surface mainly originate from the Te 5$p$ orbitals and the magnetism is dominated by localized electrons from the Eu 4$f$ orbitals. These results suggest that both the RKKY and Kondo interactions between the local moments and itinerant electrons play crucial roles in the magnetism and large negative magnetoresistance of EuTe$_2$.

description: Hedonic price modeling of 1,951 non-pasture agricultural land sales across North Dakota indicates that land enrolled in the Conservation Reserve Program (CRP) sold for 14 percent less than otherwise similar cropland over the 2000 to 2004 time period. This price discount is assumed to result from the increasing opportunity costs associated with maintaining agricultural land in conservation, particularly in light of the steadily increasing commodity prices over the study period. Similar findings have recently been reported in the adjacent state of Minnesota. These multi-state results explain why many landowners nationwide are actively lobbying the USDA to allow voluntary opt-outs of remaining CRP contracts. This may also indicate the need to either shorten the length of future CRP contracts and/or to have CRP payment values tied to commodity and/or land price indices. Continued research on this topic would be facilitated and improved with the inclusion of parcel-specific (GIS based) CRP enrollment data.

description: Introduction: There are regional differences in the morbidity of major cardiovascular disease between the 16 federal states of Germany. An association between the morbidity and the health care supply has been described in international studies. The aim of the present analysis was to examine the relationship between the prevalence or mortality of major cardiovascular disease and several key indicators of health care supply in Germany. Methods: Life expectancy and the proportion of over 65-year old persons were included as characteristics to depict the general health. Indicators of health care supply were the number of general practitioners, internists, and cardiologists, number of internal medicine and cardiology beds, chest pain units (CPU), cardiac catheterization laboratories (CCL) and stroke units. In the form of an ecological analysis, we compared the cardiovascular disease prevalence and mortality with these indicators and performed a weighted linear regression. Results: Regional variations between the federal states were found in general health and health care supply. The regression analysis yielded significant associations of the prevalence of major cardiovascular disease with the number of internal medicine hospital beds (beta = 10.042, p = 0.045), cardiologists (beta = -0.689, p = 0.031), and the number of residents per chest pain unit (beta = 42,730, p = 0.036). Additionally, the relationship between cardiovascular mortality and also the number of residents per chest pain unit appeared to be significant (beta = 4,962, p = 0.002). For all other indicators, no significant association was observed. Conclusions: We detected regional differences in the general health and health care supply between the 16 German federal states as well as several significant associations between cardiovascular morbidity and health care supply indicators. Especially the decreasing number of cardiologists and rising number of residents per chest pain unit with an increasing prevalence of major cardiovascular disease should lead to a discussion about the structure of the Germany health care system, such as the needs-based planning mechanism of physicians. The results of this study may also aid in future development of other health care systems.

description: Overexpression approaches and fluorescence microscopy techniques allow investigating important spatiotemporal aspects of gene regulation as well as quantifying gene function. Consequently, fluorescence microscopy techniques help answer important questions on gene regulation such as addressing the role of a specific gene product for neuronal survival under different treatments. Here, we describe a versatile tool to measure effects of a transfected gene of interest on neuronal survival upon metabolic stress. We focus on nutrient starvation of cultured rodent primary neurons as a model of metabolic stress but our approach can easily be generalized and adapted to other cell types or to investigate single gene function in regulating neuronal survival under various conditions.
