description: Although Generative Adversarial Networks (GANs) are successfully applied to diverse fields, training GANs on synthetic aperture radar (SAR) data is a challenging task mostly due to speckle noise. On the one hands, in a learning perspective of human's perception, it is natural to learn a task by using various information from multiple sources. However, in the previous GAN works on SAR target image generation, the information on target classes has only been used. Due to the backscattering characteristics of SAR image signals, the shapes and structures of SAR target images are strongly dependent on their pose angles. Nevertheless, the pose angle information has not been incorporated into such generative models for SAR target images. In this paper, we firstly propose a novel GAN-based multi-task learning (MTL) method for SAR target image generation, called PeaceGAN that uses both pose angle and target class information, which makes it possible to produce SAR target images of desired target classes at intended pose angles. For this, the PeaceGAN has two additional structures, a pose estimator and an auxiliary classifier, at the side of its discriminator to combine the pose and class information more efficiently. In addition, the PeaceGAN is jointly learned in an end-to-end manner as MTL with both pose angle and target class information, thus enhancing the diversity and quality of generated SAR target images The extensive experiments show that taking an advantage of both pose angle and target class learning by the proposed pose estimator and auxiliary classifier can help the PeaceGAN's generator effectively learn the distributions of SAR target images in the MTL framework, so that it can better generate the SAR target images more flexibly and faithfully at intended pose angles for desired target classes compared to the recent state-of-the-art methods.

description: Background: Medication-induced tremor (MIT) is common in clinical practice and there are many medications/drugs that can cause or exacerbate tremors. MIT typically occurs by enhancement of physiological tremor (EPT), but not all drugs cause tremor in this way. In this manuscript, we review how some common examples of MIT have informed us about the pathophysiology of tremor. Methods: We performed a PubMed literature search for published articles dealing with MIT and attempted to identify articles that especially dealt with the medication’s mechanism of inducing tremor. Results: There is a paucity of literature that deals with the mechanisms of MIT, with most manuscripts only describing the frequency and clinical settings where MIT is observed. That being said, MIT emanates from multiple mechanisms depending on the drug and it often takes an individualized approach to manage MIT in a given patient. Discussion: MIT has provided some insight into the mechanisms of tremors we see in clinical practice. The exact mechanism of MIT is unknown for most medications that cause tremor, but it is assumed that in most cases physiological tremor is influenced by these medications. Some medications (epinephrine) that cause EPT likely lead to tremor by peripheral mechanisms in the muscle (β-adrenergic agonists), but others may influence the central component (amitriptyline). Other drugs can cause tremor, presumably by blockade of dopamine receptors in the basal ganglia (dopamine-blocking agents), by secondary effects such as causing hyperthyroidism (amiodarone), or by other mechanisms. We will attempt to discuss what is known and unknown about the pathophysiology of the most common MITs.

description: We study the sea quark contribution to the BFKL kernel in the framework of Mueller's dipole model using the results of our earlier calculation. We first obtain the BFKL equation with the running coupling constant. We observe that the ``triumvirate'' structure of the running coupling found previously for non-linear evolution equations is preserved for the BFKL equation. In fact, we rederive the equation conjectured by Levin and by Braun, albeit for the unintegrated gluon distribution with a slightly unconventional normalization. We obtain the leading-N_f contribution to the NLO BFKL kernel in transverse momentum space and use it to calculate the leading-N_f contribution to the NLO BFKL pomeron intercept for the unintegrated gluon distribution. Our result agrees with the well-known results of Camici and Ciafaloni and of Fadin and Lipatov. We show how to translate this intercept to the case of the quark dipole scattering amplitude and find that it maps onto the expression found by Balitsky.

description: Geographies of the night. This intervention invites us to explore “geographies of the night” at multiple levels, in different contexts and through different approaches. If this project seeks to map out the geographies of a particular astronomical moment in the 24-hour cycle, it also aims to reflect on the emergence of a specific branch of the discipline, one with its own concepts, methods and tools. This is both a reflection “on” the night, “with” and “through” geography and an interrogation of geography from the perspective of night. In this article, we will begin by tracing the pressures which act upon the night and have made it a present-day concern, a preoccupation of public policy and an object of research in geography and across the social sciences and humanities. In a second movement, we will analyse research on the night within the discipline and trace the emergence of an interdisciplinary field of research: “night studies”. Finally, we will explore the possible contributions of a “night” turn for geography. From such a perspective, the night is simultaneously a matter, an infrastructure, an object, an environment, an ambiance and a generator of research.

description: Understanding why the scale of emergent hadron mass is obvious in the proton but hidden in the pion may rest on mapping the distribution functions (DFs) of all partons within the pion and comparing them with those in the proton; and since glue provides binding in quantum chromodynamics, the glue DF could play a special role. Producing reliable predictions for the proton's DFs is difficult because the proton is a three valence-body bound-state problem. As sketched herein, the situation for the pion, a two valence-body problem, is much better, with continuum and lattice predictions for the valence-quark and glue DFs in agreement. This beginning of theory alignment is timely because experimental facilities now either in operation or planning promise to realise the longstanding goal of providing pion targets, thereby enabling precision experimental tests of rigorous theory predictions concerning Nature's most fundamental Nambu-Goldstone bosons.

description: Background: Orthostatic tremor (OT), a rare and complex movement disorder, is characterized by rapid tremor of both legs and the trunk while standing. These disappear while the patient is either lying down or walking. OT may be idiopathic/primary or it may coexist with several neurological conditions (secondary OT/OT plus). Primary OT remains an enigmatic movement disorder and its pathogenesis and neural correlates are not fully understood. Methods: A PubMed search was conducted in July 2017 to identify articles for this review. Results: Structural and functional neuroimaging studies of OT suggest possible alterations in the cerebello-thalamo-cortical network. As with essential tremor, the presence of a central oscillator has been postulated for OT; however, the location of the oscillator within the tremor network remains elusive. Studies have speculated a possible dopaminergic deficit in the pathogenesis of primary OT; however, the evidence in favor of this concept is not particularly robust. There is also limited evidence favoring the concept that primary OT is a neurodegenerative disorder, as a magnetic resonance spectroscopic imaging study revealed significant reduction in cerebral and cerebellar N-acetyl aspartate (NAA) levels, a marker of neuronal compromise or loss. Discussion: Based on the above, it is clear that the pathogenesis of primary OT still remains unclear. However, the available evidence most strongly favors the existence of a central oscillatory network, and involvement of the cerebellum and its connections.

description: Among many unknown texts of the French geographer Pierre Deffontaines, the Introduction to a geography of sleep and night is interesting for two reasons: it is one of the last articles he publishes (1966) and he represents not only his conceptions of geography, but also the direction he wanted to give it to. This text should be considered in its context of production; it would be a condition to understand this geography of the night with a new historical approach. From an epistemological point of view, his creation is quite unusual. It will allow us to show how Deffontaines “thinks elsewhere”, as Michel de Montaigne said, quoted and analysed by Nicole Lapierre. If this composition fits well in the épistémè of his time – that of the French school of so-called classical geography – we will see how this geography of the night entitles Deffontaines to be called a precursor, a foreign thinker in the French academic world.

description: Generative models, and Generative Adversarial Networks (GAN) in particular, are being studied as possible alternatives to Monte Carlo simulations. It has been proposed that, in certain circumstances, simulation using GANs can be sped-up by using quantum GANs (qGANs). We present a new design of qGAN, the dual-Parameterized Quantum Circuit(PQC) GAN, which consists of a classical discriminator and two quantum generators which take the form of PQCs. The first PQC learns a probability distribution over N-pixel images, while the second generates normalized pixel intensities of an individual image for each PQC input. With a view to HEP applications, we evaluated the dual-PQC architecture on the task of imitating calorimeter outputs, translated into pixelated images. The results demonstrate that the model can reproduce a fixed number of images with a reduced size as well as their probability distribution and we anticipate it should allow us to scale up to real calorimeter outputs.

description: We argue that if black hole entropy arises from a finite number of underlying quantum states, then any particular such state can be identified from infinity. The finite density of states implies a discrete energy spectrum, and, in general, such spectra are non-degenerate except as determined by symmetries. Therefore, knowledge of the precise energy, and of other commuting conserved charges, determines the quantum state. In a gravitating theory, all conserved charges including the energy are given by boundary terms that can be measured at infinity. Thus, within any theory of quantum gravity, no information can be lost in black holes with a finite number of states. However, identifying the state of a black hole from infinity requires measurements with Planck scale precision. Hence observers with insufficient resolution will experience information loss.

description: Background: Pharmacological management of cervical dystonia (CD) is considered to be symptomatic in effect, rather than targeting the underlying pathophysiology of the disease. Magnetoencephalography (MEG), a direct measure of neuronal activity, while accepted as a modality for pre-surgical mapping in epilepsy, has never been used to explore the effect of pharmacotherapy in movement disorders. Methods: Resting state MEG data were collected from patients with CD, pre- and post-botulinum toxin injections. All of these patients exhibited good clinical benefit with botulinum toxin. Resting state MEG data from four age- and gender-matched healthy controls with no neurological disorders were also collected. Results: Our exploratory study reveals a difference in coherence between controls and patients in the following regions: fronto-striatal, occipito-striatal, parieto-striatal, and striato-temporal networks. In these regions there is an increase after botulinum toxin. Specifically, increased coherence in the left putamen and right superior parietal gyrus was noticeable. Both intrahemispheric and interhemispheric networks were affected. Discussion: This is the first attempt to directly assess changes in functional connectivity with pharmacotherapy using MEG. Botulinum toxin might affect sensorimotor integration, leading to clinical benefit. The presence of increased interhemispheric coherence and intrahemispheric coherence points to the importance of global and local networks in the pathophysiology of dystonia.

description: Poverty is a ubiquitous and prevalent predicament in South Asia which is home to a quarter of the world population and nearly one-third of the poor people in the world. Albeit, there has been a sizeable reduction in the poverty headcount ratio since 1990, about 256 million people remain in absolute poverty in the region. However, the region; is blessed with enthralling natural resources and cultural embodiments. These assets are promoted as tourism products which in turn would fetch foreign as well as domestic earnings. The tourism industry is experiencing sustained and substantial growth, contributing a total of 9.8% to the world GDP and 9.5% to global employment. Despite possessing incredible facets of tourism, South Asian nations haven’t been able to woo its fair share of tourists. The primary aim of this paper is to highlight the potential of tourism as a panacea for poverty issues in the South Asian context. Further, tourism-poverty studies have been mostly focused on African or Southeast Asian regions. This paper is an attempt to bridge the existing gap by assimilating the leads from various dossiers, consultancy reports, and case studies that underpin the potential of tourism in mitigating poverty in South Asia. The present work provides a broad picture of poverty issues in South Asia and also presents an in-depth review of the tourism- poverty linkages. The lacunae in terms of infrastructure, planning, and promotion in the realm of tourism in South Asia are dealt with in this paper.

description: Digital transformation is often conceptualised as an accomplished event; however, conceptualising it as something that organisations accomplish does not capture the features of the change process. In this study, we analyse digital transformation at the inter-organisational level (i.e. construction projects context) and conceptualise it as a dynamic change process that people enact. More specifically, we investigate the implementation of building information modelling (BIM) in construction projects, adopting a practice-based approach to explore the change process and how BIM is institutionalised in practice. We propose a preliminary conceptual model of the institutionalisation of BIM as a structuration process. Based on ethnographic data, our findings revealed two main characteristics of the process of institutionalising BIM in projects, i.e. path dependency and contingency upon institutional fields. Through our findings, we offer insights into both the literature and practice on how digital transformation in project-based contexts occurs in practice.

description: The aim of this study was the development of an experimental model, which could be used for the simulation of gognitive disorders that are related with disease of the central nervous system and could be also used the evaluation of pharmacologic agents that effect learning and memory. Important role in the development of the experimental model played the already published studies which had confirmed the important role of the nucleus basalis of Meynert in cognitive functions according to the cholinergic hypothesis of geriatric memory dysfunction, as well as the relation of this nuclus with the pathophysiology of Alzheimer's disease. The results of this study indicate the importance of nucleus basalis of Meynert in cognitive functions. The bilateral lesion of the nucleus basalis of meynert with ibotenic acid simulates disturbances in learning and memory processes that affect cognitive functions. Also, the lack of cholinergic adverse effects of rivastigmine in the dose that was used proves its selectivity in the inhibition of acetylcholinesterase in the cerebrax cortex and the hippocampus. Finally, it was concluded that the administration of rivastigmine after lesions of the nucleus basalis of Meynert the cognitive functions of the rats

description: Background: Head tremor may be observed in the presence of cervical dystonia and sometimes coexists with headache. We wished to investigate the presence of headache in dystonic head tremor. Methods: We studied the files of 19 patients from our outpatient clinic (1997–2017) with dystonic head tremor and assessed the co-occurrence of headache. We also performed a literature search of the topic. Results: Cervicogenic headache was present in nearly 37% of patients with dystonic head tremor. More than 85% of our patients presented with a “no-no” head tremor. Discussion: Headache is common in dystonic head tremor. Cervicogenic headache seems to be more frequent in patients with dystonic head tremor than in the general population. Future studies should compare the presence of cervicogenic headache in essential head tremor patients with that in patients suffering from dystonic head tremor.

description: MSME's across the country which depends on cash transactions and not on electronic cash transactions bore the brunt of the demonetization policy declared on November 8, 2016. This study analyses the regulations which were originally enforced, then altered and reintroduced in a different format in a very short span of time has given rise to various undercurrents that affects tourism business. With respect to tourism, demonetization was a jolt as the policy decision came into force in the peak season, i.e., during the months of October–December when the tourist arrivals are usually high. Framed as a qualitative study in an exploratory mode adopting the Delphi Technique for deriving the inferences and apt deductions, this paper emphasizes the reviews of media reports for preparing the statements for the Panel configuring eminent tourism industry practitioners, academicians, consultants, NGO activists, and banking personnel. Further, an academic prediction regarding the nature and implications of the return to normalcy of tourism based on the assessment of the developments in the contemporary paradigm shift to the much proclaimed transparent economy. Also, the discrepancies involved in streamlining the denominations of currency notes are also discussed.

description: Background: The dystonias include a clinically and etiologically very diverse group of disorders. There are both degenerative and non-degenerative subtypes resulting from genetic or acquired causes. Traditionally, all dystonias have been viewed as disorders of the basal ganglia. However, there has been increasing appreciation for involvement of other brain regions including the cerebellum, thalamus, midbrain, and cortex. Much of the early evidence for these other brain regions has come from studies of animals, but multiple recent studies have been done with humans, in an effort to confirm or refute involvement of these other regions. The purpose of this article is to review the new evidence from animals and humans regarding the motor network model, and to address the issues important to translational neuroscience. Methods: The English literature was reviewed for articles relating to the neuroanatomical basis for various types of dystonia in both animals and humans. Results: There is evidence from both animals and humans that multiple brain regions play an important role in various types of dystonia. The most direct evidence for specific brain regions comes from animal studies using pharmacological, lesion, or genetic methods. In these studies, experimental manipulations of specific brain regions provide direct evidence for involvement of the basal ganglia, cerebellum, thalamus and other regions. Additional evidence also comes from human studies using neuropathological, neuroimaging, non-invasive brain stimulation, and surgical interventions. In these studies, the evidence is less conclusive, because discriminating the regions that cause dystonia from those that reflect secondary responses to abnormal movements is more challenging. Discussion: Overall, the evidence from both animals and humans suggests that different regions may play important roles in different subtypes of dystonia. The evidence so far provides strong support for the motor network model. There are obvious challenges, but also advantages, of attempting to translate knowledge gained from animals into a more complete understanding of human dystonia and novel therapeutic strategies.

description: We have demonstrated the advantage of combining multi-wavelength observations, from the ultraviolet (UV) to near-infrared, to study Kron 3, a massive star cluster in the Small Magellanic Cloud. We have estimated the radius of the cluster Kron 3 to be 2.'0 and for the first time, we report the identification of NUV-bright red clump (RC) stars and the extension of the RCin colour and magnitude in the NUV vs (NUV-optical) colour-magnitude diagram (CMD). We found that extension of the RC is an intrinsic property of the cluster and it is not due to contamination of field stars or differential reddening across the field. We studied the spectral energy distribution of the RC stars and estimated a small range in temperature ~5000 - 5500K, luminosity ~60 - 90 Land radius ~8.0 - 11.0 Supporting their RC nature. The range of UV magnitudes amongst the RC stars (~23.3 to 24.8 mag) is likely caused by the combined effect of variable mass loss, variation in initial helium abundance (Y_ini=0.23 to 0.28), and a small variation in age (6.5-7.5 Gyr) and metallicity ([Fe/H]=-1.5 to -1.3). Spectroscopic follow-up observations of RC stars in Kron 3 are necessary to confirm the cause of the extended RC.

description: The braneworld theory appear with the purpose of solving the problem of the hierarchy of the fundamental interactions. The perspectives of the theory emerge as a new physics, for example, deviation of the law of Newton's gravity. One of the principles of the theory is to suppose that the braneworld is local submanifold in a space of high dimension, the bulk, solution of Einstein's equations in high dimension. In this paper we approach the mathematical consistency of this theory with a new proof of the fundamental theorem of submanifolds for case of semi-Riemannian manifolds. This theorem consist an essential mathematical support for this new theory. We find the integrability conditions for the existence of space-time submanifolds in a pseudo-Euclidean space. Keywords: Submanifolds, Braneworld, Pseudo-Riemannian geometry

description: The tourism and hospitality industry in a service sector is nothing but consuming services and gaining new experiences. The success or failure of this industry depends on the quality of services available at the destination. At present, tourism has become a booming industry in India and there has been a huge shift in tourists’ attitude from the back of the bus, five-star tour to something more interactive and in that connection, the rural tourism plays an important role. But it is unfortunate that most of the time, while promoting such destination we overlook the quality of available services. Therefore, many a time even if any rural destination has great tourism potentials, it fails to grab the tourists’ attention. In this paper the researchers have found that there is a connection in between service quality and destination loyalty through tourist's satisfaction at any place, and destination loyalty ensures increasing volume of tourists at a destination that leads towards the sustained tourism. In this paper the researchers have mentioned the ‘Shaam-E-Sarhad’ Village Resort, situated in Hodka Village in the state of Gujarat, India, as a case study to examine the relationship between tourism service quality and destination loyalty. Both qualitative and quantitative data have been used in this study. Tourists’ feedbacks have been taken from the TripAdvisor. Inc. Finally, Content Analysis Method’ has been adapted to analyze the data regarding Service Quality, Satisfaction and Destination Loyalty from the tourists‘ feedbacks to examine their Interrelationship.

description: The orbital parameters of dark matter (DM) subhaloes play an essential role in determining their mass-loss rates and overall spatial distribution within a host halo. Haloes in cosmological simulations grow by a combination of relatively smooth accretion and more violent mergers, and both processes will modify subhalo orbits. To isolate the impact of the smooth growth of the host halo from other relevant mechanisms, we study subhalo orbital evolution using numerical calculations in which subhaloes are modelled as massless particles orbiting in a time-varying spherical potential. We find that the radial action of the subhalo orbit decreases over the first few orbits, indicating that the response to the growth of the host halo is not adiabatic during this phase. The subhalo orbits can shrink by a factor of $\sim$1.5 in this phase. Subsequently, the radial action is well conserved and orbital contraction slows down. We propose a model accurately describing the orbital evolution. Given these results, we consider the spatial distribution of the population of subhaloes identified in high-resolution cosmological simulations. We find that it is consistent with this population having been accreted at z < 3, indicating that any subhaloes accreted earlier are unresolved in the simulations. We also discuss tidal stripping as a formation scenario for NGC1052-DF2, an ultra diffuse galaxy significantly lacking DM, and find that its expected DM mass could be consistent with observational constraints if its progenitor was accreted early enough, z > 1.5, although it should still be a relatively rare object.

description: We use a set of simulation-based models for the dissipationless evolution of galaxies since z=1 to constrain the fate of accreted satellites embedded in dark matter subhalos. These models assign stellar mass to dark matter halos at z=1 by relating the observed galaxy stellar mass function (GSMF) to the halo+subhalo mass function monotonically. The evolution of the stellar mass content is then followed using halo merger trees extracted from N-body simulations. Our models are differentiated only in the fate assigned to satellite galaxies once subhalos, within which satellites are embedded, disrupt. These models are confronted with the observed evolution in the massive end of the GSMF, the z~0 brightest cluster galaxy (BCG)-cluster mass relation, and the combined BCG and intracluster light (ICL) luminosity distribution -- all observables expected to evolve approximately dissipationlessly since z=1. The combined observational constraints favor a model in which the vast majority (>80%) of satellite stars from disrupted subhalos go into the ICL. Conversely, models that leave behind a significant population of satellite galaxies once the subhalo has disrupted are strongly disfavored, as are models that put a significant fraction of satellite stars into the BCG. Our results show that observations of the ICL provide useful and unique constraints on models of galaxy merging and the dissipationless evolution of galaxies in groups and clusters.

description: Η όραση μετά την προσοχή αποτέλεσε μόλις προσφάτως το αντικείμενο πειραματικών ερευνών στο χώρο της ψυχολογίας, μετά από ένα μεγάλο αριθμό ερευνών πάνω στον τομέα της όρασης πριν την προσοχή. Το βασικό ερώτημα ήταν υπό ποιες συνθήκες είναι δυνατό η όραση μετά την προσοχή να οδηγήσει σε αποτελεσματική οπτική αναζήτηση, καθώς η προηγούμενη έρευνα έδειξε ότι τα οποιαδήποτε οφέλη της προσοχής εξαφανίζονται, μόλις αυτή μεταφερθεί σε κάποιο άλλο σημείο του οπτικού πεδίου ενός παρατηρητή. Η παρούσα έρευνα χρησιμοποίησε ένα σχετικά μεγάλο δείγμα συμμετεχόντων σε πειράματα οπτικής αναζήτησης. Σε αυτά νέες πειραματικές συνθήκες εφαρμόστηκαν και έδειξαν σε ποιο βαθμό μπορεί η όραση μετά την προσοχή να οδηγήσει σε αποτελεσματική οπτική αναζήτηση, σε σύγκριση με την όραση πριν την προσοχή και την όραση με προσοχή. Πιο συγκεκριμένα, η επιστροφή της προσοχής σε σημεία όπου εστιάστηκε νωρίτερα, η αποτελεσματική καθοδήγησή της στο σημείο της επόμενης εστίασης και η διατήρηση πληροφοριών στη βραχύχρονη μνήμη μπορούν να προκαλέσουν αποτελεσματική οπτική αναζήτηση μέσω της όρασης μετά την προσοχή. Βέβαια τα οποιαδήποτε οφέλη δεν είναι δυνατό να ξεπεράσουν την οπτική αναζήτηση με προσοχή, εκτός αν ληφθεί υπόψη ο χρόνος αντίδρασης. Ωστόσο είναι σημαντικό να επισημανθεί η υπεροχή της όρασης μετά την προσοχή έναντι της όρασης πριν την προσοχή, εφόσον διασφαλίζεται η διατήρηση των πληροφοριών στη βραχύχρονη μνήμη, όπως έδειξε καθαρά η πειραματική διαδικασία
description: Postattentive vision has been quite recently the subject of investigation by experimental psychologists, following a great number of studies in preattentive vision. The essential question is under what conditions visual search via postattentive vision can be effective, since previous research showed that attentive gains vanish when attention is deployed elsewhere. This study used a relatively large number of subjects that participated in visual search experiments. In these, new experimental conditions have been introduced that showed to what extent postattentive vision can be efficient in comparison with attentive and preattentive vision. In particular, recurrence of previously attented stimuli, guidance of attention and maintenance of information in short-term memory can produce effective visual search via postattentive vision. Of course, any gains can not outrun visual search via attentive vision, unless reaction time is taken into account. However it is important to note that postattentive visual search is superior to preattentive provided that information is maintained in short-term memory, as clearly shown by the experimental process
