description: We report the discovery of a partial ~2deg. diameter non-thermal radio shell coincident with Taz, the pulsar wind nebula (PWN) in the error box of the apparently variable gamma-ray source 3EG J1809-2328. We propose that this radio shell is a newly identified supernova remnant (SNR G7.5-1.7) associated with the PWN. The SNR surrounds an amorphous region of thermal X-rays detected in archival ROSAT and ASCA observations putting this system in the mixed-morphology class of supernova remnants. G7.5-1.7 is the fifth such supernova remnant coincident with a bright GeV source, and the fourth containing a pulsar wind nebulae.

description: We present new photometric and spectroscopic observations and analyses for the eclipsing binary systems V1241 Tau and GQ Dra. Our photometric light and radial velocity curves analyses combining with the TESS light curves show that both are conventional semi-detached binary systems. Their absolute parameters are also derived. We present the $O-C$ analyses of the systems and we propose the most possible orbital period modulating mechanisms. Furthermore, Fourier analyses are applied to the photometric residual data of the systems to check for the pulsational behavior of the components. We conclude that the primary component of the system GQ Dra is a $δ$ Sct type pulsator with a dominant pulsation frequency of 18.58 d$^{-1}$ based on our $B$ filter residual light curve although it can not be justified by 30-minute cadence TESS data. No satisfactory evidence of pulsational behaviour for V1241 Tau was verified. Finally, the evolutionary tracks of the components of both systems are calculated, while their locations within evolutionary diagrams are compared with other Algol-type systems.

description: Rintracciare il passato traumatico dopo un disastro sociale non è semplice. Ciò presuppone uno specifico processo di raccoglimento che mobiliti una narrazione per definizione polifonica, cioè a più voci. Kaës avanza la nozione di ‘ricordo’ per qualificare il fatto di ricollegare tra loro pezzi, brandelli, frammenti sparsi del tessuto della memoria. Ma quali sono le molle narrative e più ampiamente discorsive di una simile operazione? E quali sono, da un lato, le questioni etiche e morali, e dall’altro, le questioni legate all’identificazione? Cercheremo di identificare l’utilità di una concezione narrativa dell’identità personale per far luce su queste questioni che affronteremo analizzando in dettaglio un estratto de L’Ecriture ou la vie di Jorge Semprun. La storia, infatti, dà un posto singolare a una canzone che, per lo sconvolgimento degli scenari narcisistici in cui è preso l’autore, creerà momentaneamente un effetto di rottura inaspettato nella storia.

description: We propose and analyze a numerical algorithm for solving a class of optimal control problems for learning-informed semilinear partial differential equations. The latter is a class of PDEs with constituents that are in principle unknown and are approximated by nonsmooth ReLU neural networks. We first show that a direct smoothing of the ReLU network with the aim to make use of classical numerical solvers can have certain disadvantages, namely potentially introducing multiple solutions for the corresponding state equation. This motivates us to devise a numerical algorithm that treats directly the nonsmooth optimal control problem, by employing a descent algorithm inspired by a bundle-free method. Several numerical examples are provided and the efficiency of the algorithm is shown.

description: Background: Progressive supranuclear palsy (PSP) is a rare neurodegenerative disease causing parkinsonian symptoms. Altered DNA methylation of the microtubule-associated protein tau gene correlates with the expression changes in Alzheimer's disease and Parkinson's disease brains. However, few studies examine the sequences beyond the constitutive promoter.Objectives: Because activating different microtubule associated protein tau gene control regions via methylation might regulate the differential tau expression constituting the specific signatures of individual tauopathies, we compared methylation of a candidate promoter, intron 0.Methods: We assessed DNA methylation in the brains of patients with different tauopathies (35 Alzheimer's disease, 10 corticobasal degeneration, and 18 PSP) and 19 controls by intron 0 pyrosequencing. We also evaluated methylation in an independent cohort of 11 PSP cases and 12 controls. Frontal (affected by tau pathology) and occipital (unaffected) cortices were analyzed.Results: In the initial samples, one CpG island site in intron 0 (CpG1) showed significant hypomethylation in PSP-affected frontal cortices when compared with controls (p = 0.022). Such hypomethylation was observed in replicate samples, but not in occipital cortices or other tauopathies. PSP and control samples (combining the initial and replicate samples) remained significantly different after adjustment for potential confounding factors (age, H1/H1 diplotype; p = 0.0005). PSP-affected tissues exhibited microtubule-associated protein tau RNA hyperexpression when compared with controls (p = 0.004), although no correlation with CpG1 methylation was observed.Conclusions: This exploratory study suggests that regions other than the constitutive promoter may be involved in microtubule-associated protein tau gene regulation in tauopathies and that intron 0 hypomethylation may be a specific epigenetic signature of PSP. These preliminary findings require confirmation.

description: BACKGROUND: Spinocerebellar ataxia types 19 and 22 (SCA19/22) are rare conditions in which relatively isolated cerebellar involvement is frequently associated with cognitive impairment. Here, we report on new clinical features and provide details of the cognitive profile in two SCA19/22 families.METHODS: Two families displaying an autosomal-dominant form of cerebellar ataxia underwent clinical examinations and genetic testing.RESULTS: In addition to the classical clinical features of SCA, a wide spectrum of cognitive disorders (including visuospatial impairments) was observed. Eight patients had mild Parkinsonism, and five had epilepsy. Genetic testing showed that the KCND3 mutation (c.679_681delTTC, p.F227del) was present in both families.CONCLUSIONS: Our findings broaden the phenotypic spectrum of SCA19/22, and suggest that KCND3 should be included in the list of candidate genes for epilepsy, Parkinsonism and cognitive impairment.

description: We prove the existence of a solution to an equation governing the number density within a compact domain of a discrete particle system for a prescribed class of particle interactions taking into account the effects of the diffusion and drift of the set of particles. Each particle carries a number of internal coordinates which may evolve continuously in time, determined by what we will refer to as the internal drift, or discretely via the interaction kernels. Perfectly reflecting boundary conditions are imposed on the system and all the processes may be spatially and temporally inhomogeneous. We use a relative compactness argument to construct a sequence of measures that converge weakly to a solution of the governing equation. Since the proof of existence is a constructive one, it provides a stochastic approximation scheme that can be used for the numerical study of molecular dynamics.

description: An assumption of smooth response to small parameter changes, of statistics or long-time averages of a chaotic system, is generally made in the field of sensitivity analysis, and the parametric derivatives of statistical quantities are critically used in science and engineering. In this paper, we propose a numerical procedure to assess the differentiability of statistics with respect to parameters in chaotic systems. We numerically show that the existence of the derivative depends on the Lebesgue-integrability of a certain density gradient function, which we define as the derivative of logarithmic SRB density along the unstable manifold. We develop a recursive formula for the density gradient that can be efficiently computed along trajectories, and demonstrate its use in determining the differentiability of statistics. Our numerical procedure is illustrated on low-dimensional chaotic systems whose statistics exhibit both smooth and rough regions in parameter space.

description: Physical systems may couple to other systems through variables that are not gauge invariant. When we split a gauge system into two subsystems, the gauge-invariant variables of the two subsystems have less information than the gauge invariant variables of the original system; the missing information regards degrees of freedom that express relations between the subsystems. All this shows that gauge invariance is a formalization of the relational nature of physical degrees of freedom. The recent developments on boundary variables and boundary charges are clarified by this observation.

description: Delta-self-consistent field theory (delta-SCF) is a conceptually simple and computationally inexpensive method for finding excited states. Using the maximum overlap method to guide optimization of the excited state, delta-SCF has been shown to predict excitation energies with a level of accuracy that is competitive with, and sometimes better than, that of TDDFT. Here we benchmark delta-SCF on a larger set of molecules than has previously been considered, and, in particular, we examine the performance of delta-SCF in predicting transition dipole moments, the essential quantity for spectral intensities. A potential downfall for delta-SCF transition dipoles is origin dependence induced by the nonorthogonality of delta-SCF ground and excited states. We propose and test the simplest correction for this problem, based on symmetric orthogonalization of the states, and demonstrate its use on bacteriochlorophyll structures sampled from the photosynthetic antenna in purple bacteria.

description: Systems biology modelling involves the mathematical representation of biological processes to study complex system behaviour and was expected to be less affected by the reproducibility crisis. However, models often fail to reproduce and the reasons for the failure and prevalence were not fully understood. We analyzed 455 kinetic models published in 152 peer-reviewed journals. Most of these models were manually encoded from scratch to assess reproducibility. Our investigation revealed that 49% of the models could not be reproduced using the information provided in the manuscripts. With further effort, an additional 12% could be reproduced either by empirical correction or support from authors. The other 37% remained non-reproducible due to missing parameter values, missing initial concentration, or inconsistent model structure. Among the corresponding authors, we contacted <30% responded. Models from many life science journals failed to reproduce, revealing a common problem in the peer-review process. Hence, we proposed a reproducibility scorecard to assess each model and address the reproducibility crisis. The aim of this scorecard is to help evaluate the reproducibility of the systems biology model and its simulation. It consists of eight questions with a unit score for each “yes” as an answer. The higher the total score, the more reproducible the model is expected to be. All eight questions may not always be applicable and hence, on the scale of 8, a minimum score of 4 is recommended. Model authors, reviewers, and journal editors can assess each systems biology model in a manuscript using this scorecard to support the peer-review process.

description: Metal Organic Frameworks (MOFs) are a type of multifunctional porous material. Comprised of metal centres or metal clusters known as Secondary Building Units (SBUs) linked together into an extended 1, 2 or 3 dimensional structure by bridging organic ligands coordinated to the metal SBUs. MOFs offer the opportunity to customise the pore size and chemical functionality of the fra mework. The degree of customisation possible from the wide array of different metal clusters and organic ligands MOFs have been proposed for many applications such as gas storage, separation, catalysis, photocatalysis, sensing and drug delivery. In this thesis the synthesis and characterisation of pyrene based MOFs is presented and the hydrogen evolution photocatalytic applications are tested. This thesis contains details on three different MOFs. Firstly a new aluminium pyrene MOF which was characterised and tested for photocatalysis and CO 2 and CH 4 storage applications; which also had platinum nanoparticles successfully incorporated within the pores. Secondly a very recently reported zirconium pyrene MOF was made, had its photocatalytic applications exp lored for the first time and had platinum deposited within the pores. Thirdly a new Europium Pyrene MOF was developed using high throughput techniques and its new structure was calculated from single crystal XRD.

description: We are studying the influence of stellar multiplicity on exoplanet systems, in particular systems that have been detected via radial-velocity searches. We are in particular interested in the closest companions as they would have a strong influence on the evolution of the original planet forming disks. In this study we present new companions detected during our ongoing survey of exoplanet hosts with VLT/SPHERE. We are using the extreme adaptive optics imager SPHERE at the ESO/VLT to search for faint (sub)stellar companions. We utilized the classical coronagraphic imaging mode to perform a snapshot survey (3-6 min integration time) of exoplanet host stars in the Ks-band. We detected new stellar companions to the exoplanet host stars HD1666, HIP68468, HIP107773, and HD109271. With an angular separation of only 0.38" (40 au of projected separation) HIP107773 is among the closest companions found to exoplanet host stars. The presence of the stellar companion explains the linear radial-velocity trend seen in the system. At such a small separation the companion likely had significant influence on the evolution of the planet forming disk around the primary star. We find that the companion in the HD1666 system may well be responsible for the high orbit eccentricity (0.63) of the detected Jupiter class planet, making this system one of only a few where such a connection can be established. A cross-match with the Gaia DR2 catalog showed furthermore that the near infrared faint companion around HD109271 had been detected in the optical and is significantly brighter than in the near infrared making it a white dwarf companion.

Fred Dretske’s information-based theory of intentional states
Creators: name: Smart, Brent Maxwell
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this dissertation is to advance our understanding of the intentionality of mental states through a critical examination of Fred Dretske's theory of mind. Dretske's theorizing is constrained by his desire both to save central features of our "pretheoretic" conception of mind and, at the same time, to be appropriately "materialistic" (and hence "naturalistic"). Dretske's materialism is captured in his claim that: "...the crucial point is that whatever set of facts we select to analyze the mental are facts which, taken individually, are recognizably physical — the sort that exist, or can exist, in a world devoid of minds" (Dretske 1994a, p. 131). Central features of our pretheoretic conception of mind that Dretske wishes to preserve include: - that ordinary categories such as thought, belief, and desire capture real categories of mental states, - that mental states are certain kinds of representational states, and therefore they have semantic content (meaning), - that a mental state's having a particular representational content is an explanatorily relevant (because causally relevant) fact about it. Dretske proposes that intentional, representational contents of the cognitive states of a cognitive system are fixed by the history of information-bearing relations (also called "indicational" relations) that those states of the system have had to aspects of the system's environment. Further, the resulting representational contents are themselves essentially and entirely relational in nature. One cognitive system with an internal configuration type-identical to another, but with type-distinct (or in the limiting case no) history of indicational relations to its environment, will have type-distinct (or in the limiting case no) representational contents. Within these constraints, then, Dretske must show both how mental representation is possible and also how it is causal-explanatorily relevant to behaviour. As such, it is indicational relations that need to provide the basis both for an account of how a cognitive state comes to have its given content, and also for an account of the causal-explanatory role that its having that very content may have for the behaviour of the cognitive system whose state it is. However, 1 argue that indicational relations per se can do neither. This is so particularly on Dretske's own, strong, conception of indication. Buiiit even on weaker conceptions proposed by others as a remedy, factors which ought to count as intentional by Dretske's own lights (and which are importantly non-relational) become important contributors to intentional content determination in a way that would commit the overall account to a general and pervasive circularity. 1 argue that some of these factors, having to do with matters of "receptivity" and perceptual "discrimination", are endemic to the very processes of operant conditioning that Dretske must appeal to as contributing to the rise of states with intentional contents.

description: We study theoretically the deterministic dynamics of single-domain ferromagnetic nanoparticles in dilute ferrofluids, which is induced by a time-varying gradient magnetic field. Using the force and torque balance equations, we derive a set of the first-order differential equations describing the translational and rotational motions of such particles characterized by small Reynolds numbers. Since the gradient magnetic field generates both the translations and rotations of particles, these motions are coupled. Based on the derived set of equations, we demonstrate this fact explicitly by expressing the particle position through the particle orientation angle, and vice versa. The obtained expressions are used to show that the solution of the basic set of equations is periodic in time and to determine the intervals, where the particle coordinate and orientation angle oscillate. In addition, this set of equations is solved approximately for the case of small characteristic frequency of the particle oscillations. With this condition, we find that all particles perform small translational oscillations near their initial positions. In contrast, the orientation angle oscillates near the initial angle only if particles are located in the vicinity of zero point of the gradient magnetic field. The possible applications of the obtained results in biomedicine and separation processes are also discussed.

description: We study a mesoscopic interacting quantum dot described by the "universal Hamiltonian" that is coupled to a Kondo spin. The ferromagnetic exchange interaction within the dot leads to a stepwise increase of the ground state spin; this Stoner staircase is modified non-trivially by the Kondo interaction. We find that the spin-transition steps move to lower values of the exchange coupling for weak Kondo interaction, but shift back up for sufficiently strong Kondo coupling. The problem is solved numerically by diagonalizing the system Hamiltonian in a customized good-spin basis and analytically in the weak and strong Kondo coupling limits. The interplay of Kondo and ferromagnetic exchange can be probed with experimentally tunable parameters.

description: We perform direct numerical simulation (DNS) and large eddy simulation (LES) of an initially spherical region of turbulence evolving in free space. The computations are performed with a lattice Green's function method, which allows the exact free-space boundary conditions to be imposed on a compact vortical region. LES simulations are conducted with the stretched vortex sub-grid stress model. The initial condition is spherically windowed, isotropic homogeneous incompressible turbulence. We study the spectrum and statistics of the decaying turbulence and compare the results with decaying isotropic turbulence, including cases representing different low wavenumber behavior of the energy spectrum (i.e. k^2 versus k^4). At late times the turbulent sphere expands with both mean radius and integral scale showing similar time-wise growth exponents. The low wavenumber behavior has little effect on the inertial scales, and we find that decay rates follow Saffman (1967) predictions in both cases, at least until about 400 initial eddy turnover times. The boundary of the spherical region develops intermittency and features ejections of vortex rings. These are shown to occur at the integral scale of the initial turbulence field and are hypothesized to occur due to a local imbalance of impulse on this scale.

description: We analyze the neutrino mass spectrum and discuss the extra-dimensional interpretation of a three-site Pati-Salam model which i) unifies all families of quark and leptons, ii) provides a natural description of the Standard Model Yukawa couplings, iii) could account for the recent $B$-physics anomalies. The key feature of the model is a breaking of the Pati-Salam and electroweak gauge symmetries localized on opposite sites, communicated to the other sites in an attenuated manner via nearest-neighbor interactions. We show that in this context gauge-singlet fermions localized on each site, receiving hierarchical Majorana masses, can allow the implementation of an inverse seesaw mechanism leading to light anarchic neutrino masses consistent with data. The continuum limit of this three-site setup has a natural interpretation in terms of a warped extra dimension with three defects, where the required exponential hierarchies can be achieved from $\mathcal{O}(1)$ differences in the bulk field masses.

description: The literature on the pathogenic trypanosomes affecting domestic pigs is reviewed. Two of these are primary pig pathogens, namely Trypanosoma simiae and Trypanosoma suis. Three others affect pigs as well as other domestic stock, namely, Trypanosoma congolense, Trypanosoma brucei and Trypanosoma evansi. Taxonomy and morphology of the trypanosomes are discussed briefly and their current distribution reviewed. A short history of each pathogenic pig trypanosome is given and the following aspects of each disease presented: Fly transmission, development in the fly and the mammalian host, host-parasite relations, epidemiology, treatment and control. The extreme virulence of T. simiae for the pig has resulted in it being the most extensively investigated parasite and the majority of the literature pertains to this species. T. suis has only been discovered three or four times in pigs and very little is known of its pathogenesis. T. brucei and T. congolense generally result in a more chronic disease, causing ill-thrift and decreased production and hence are not diagnosed as often as might be expected. However, they are likely to become more important with intensification of pig-raising in the tropics. The role of the pig as a reservoir of T. evansi for other domestic stock is looked at, clinical disease being seen uncommonly. A lot of attention has been given recently to the likely part played by the village pig as a reservoir of human sleeping sickness, particularly Trypanosoma b. gambiense and this is debated and the literature reviewed. The infections are mainly inapparent, trypanosomes being harboured for many months. A major stumbling block has been in differentiating T. _b. gambiense from T. b. brucei of animal origin. Recent tests have been developed to facilitate this and these are discussed together with their future role. The possible role of the pig as a reservoir of T. b. rhodesiense and Trypanosoma cruzi is mentioned, although little is known of their connection with the epidemiology of the diseases. In conclusion, many aspects of pig trypanosomiases still remain to be investigated and possible avenues for future research are appraised.

description: Spatial Fluorescence Cross Correlation Spectroscopy is a rarely investigated version of Fluorescence Correlation Spectroscopy, in which the fluorescence signals from different observation volumes are cross-correlated. In the reported experiments, two observation volumes, typically shifted by a few $μ$m, are produced, with a Spatial Light Modulator and two adjustable pinholes. We illustrated the feasibility and potentiality of this technique by: i) measuring molecular flows, in the range 0.2 - 1.5 $μ$m/ms, of so-lutions seeded with fluorescent nanobeads or rhodamine molecules (simulating active transport phenomenons); ii) investigating the permeability of the phospholipidic membrane of Giant Unilamellar Vesicles versus hydrophilic or hydrophobic molecules (in that case the laser spots were set on both sides of the membrane). Theoretical descriptions are proposed together with a discus-sion about Fluorescence Correlation Spectroscopy based, alternative methods.

description: In online review sites, the analysis of user feedback for assessing its helpfulness for decision-making is usually carried out by locally studying the properties of individual reviews. However, global properties should be considered as well to precisely evaluate the quality of user feedback. In this paper we investigate the role of deviations in the properties of reviews as helpfulness determinants with the intuition that "out of the core" feedback helps item evaluation. We propose a novel helpfulness estimation model that extends previous ones with the analysis of deviations in rating, length and polarity with respect to the reviews written by the same person, or concerning the same item. A regression analysis carried out on two large datasets of reviews extracted from Yelp social network shows that user-based deviations in review length and rating clearly influence perceived helpfulness. Moreover, an experiment on the same datasets shows that the integration of our helpfulness estimation model improves the performance of a collaborative recommender system by enhancing the selection of high-quality data for rating estimation. Our model is thus an effective tool to select relevant user feedback for decision-making.

description: We present the latest results from the UKQCD/RBC collaborations for the K_{l3} form factor with 2+1 flavours of dynamical domain wall quarks. Simulations are performed on 16^3x32x16 and 24^3x64x16 lattices with three values of the light quark mass, allowing for an extrapolation to the chiral limit. After interpolating to zero momentum transfer, we obtain the preliminary result f_+^{Kπ}(0)=0.9680(16), which is in excellent agreement with an earlier N_f=2 result.

description: In this work we describe a new deep learning approach for automatic sleep staging, and carry out its validation by addressing its generalization capabilities on a wide range of sleep staging databases. Prediction capabilities are evaluated in the context of independent local and external generalization scenarios. Effectively, by comparing both procedures it is possible to better extrapolate the expected performance of the method on the general reference task of sleep staging, regardless of data from a specific database. In addition, we examine the suitability of a novel approach based on the use of an ensemble of individual local models and evaluate its impact on the resulting inter-database generalization performance. Validation results show good general performance, as compared to the expected levels of human expert agreement, as well as state-of-the-art automatic sleep staging approaches

description: We report the dielectric properties of improper ferroelectric h-ErMnO$_3$. From the bulk characterisation we observe a temperature and frequency range with two distinct relaxation-like features, leading to high and even 'colossal' values for the dielectric permittivity. One feature trivially originates from the formation of a Schottky barrier at the electrode-sample interface, whereas the second one relates to an internal barrier layer capacitance (BLC). The calculated volume fraction of the internal BLC (of 8 %) is in good agreement with the observed volume fraction of insulating domain walls (DWs). While it is established that insulating DWs can give rise to high dielectric constants, studies typically focused on proper ferroelectrics where electric fields can remove the DWs. In h-ErMnO$_3$, by contrast, the insulating DWs are topologically protected, facilitating operation under substantially higher electric fields. Our findings provide the basis for a conceptually new approach to engineer materials exhibiting colossal dielectric permittivities using domain walls in improper ferroelecctrics with potential applications in electroceramic capacitors.
