description: We show that discrete synaptic weights can be efficiently used for learning in large scale neural systems, and lead to unanticipated computational performance. We focus on the representative case of learning random patterns with binary synapses in single layer networks. The standard statistical analysis shows that this problem is exponentially dominated by isolated solutions that are extremely hard to find algorithmically. Here, we introduce a novel method that allows us to find analytical evidence for the existence of subdominant and extremely dense regions of solutions. Numerical experiments confirm these findings. We also show that the dense regions are surprisingly accessible by simple learning protocols, and that these synaptic configurations are robust to perturbations and generalize better than typical solutions. These outcomes extend to synapses with multiple states and to deeper neural architectures. The large deviation measure also suggests how to design novel algorithmic schemes for optimization based on local entropy maximization.

description: The essay provides an overview of the multifaceted ways in which the physical remains of the Berlin Wall have been distributed not only within Berlin but in the whole world by contrasting the official process of memorialisation and the continuous production and commerce of fragments of concrete pertaining to the Berlin Wall. This highlights issues deeply enmeshed in the city urban policies, as well as the ever-problematic theme of memory through monuments and of the progressive loss of meaning of the single fragments. By way of the commodification of the Berlin Wall remains (not only through souvenirs, but also through the auction of whole segments) the still-circulating, actual concrete of the Wall becomes less and less meaningful than – paradoxically – its absence.
Star Formation at milli-arcsecond resolution

description: This chapter discusses the use and possibilities of optical and infrared interferometry to study star formation. The chapter starts with a brief overview of the star formation process and highlights the open questions from an observational point of view. These are found at the smallest scales, as this is, inevitably, where all the action such as accretion and outflows, occurs. We then use basic astrophysical concepts to assess which scales and conditions can be probed with existing interferometric set-ups for which we use the ESO/VLTI instrument suite as example. We will concentrate on the more massive stars observed at high resolution with continuum interferometry. Throughout, some of the most recent interferometric results are used as examples of the various processes discussed.

Subjects: Medical sciences

description: The purpose of this study was to evaluate the effects of pomegranate extract (PE) on anaerobic exercise and flow mediated dilation (FMD). In a randomized, crossover design, nineteen participants completed repeated sprint ability (RSA) tests and repetitions to fatigue (RTF) on bench press and leg press with consumption of PE or placebo. Brachial artery FMD was assessed by ultrasound to determine blood flow and vessel diameter. FMD was assessed at baseline, 30min post ingestion, immediately post exercise (IPost), and 30min post exercise (30minPostEx). With PE, blood flow significantly increased IPost RSA (mean difference [MD]=18.49 mL·min-1; p=0.05), and IPost and 30minPostEx RTF (p<0.05). Vessel diameter increased significantly 30minPostEx of RSA, and IPost and 30minPostEx RTF (p<0.05). With PE, power output increased significantly halfway (sprint 5 of 10) through the RSA (MD=31.81 Watts; p=0.046). Supplementation of PE augmented vessel diameter, blood flow and power, supporting ergogenic effects and enhanced vasodilation.

description: The problem of construction of a quantum master equation for a system of sites weakly coupled to each other and to one or more reservoirs (open quantum network) is considered. Microscopic derivation of a quantum master equation requires a diagonalization of the Hamiltonian of the network, which can be a difficult task. When the inter-site couplings are weak, the local approach, which neglects the influence of the inter-site couplings on the system-reservoir couplings, is often used. Recently, some doubts were cast to the consistency of the local approach. We develop a systematic perturbation expansion to derive corrections to the local approach and establish its range of validity. Using this extension of the local approach, we derive an expression for the heat flux for a particular model and show that it does not violate the second law of thermodynamics.

description: Σκοπός της παρούσας εργασίας είναι η συγκριτική μελέτη των διαμορφωμένων συνδετήρων, από εννέα διαφορετικά συρραπτικά δέρματος, ως προς την αντοχή στην κάμψη. Αρχικά, τέθηκε η μηδενική υπόθεση ότι όλοι οι συνδετήρες διέθεταν παρόμοια αντοχή σε εξωτερικές δυνάμεις κάμψης. Στη συγκριτική μελέτη έλαβαν μέρος 9 ομάδες συνδετήρων (n=6), που μετά την πυροδότηση των συρραπτικών τους, διαμορφώθηκαν σε ορθογώνιες ή κυκλικές διατομές. Έπειτα, κάθε διαμορφωμένος συνδετήρας τοποθετήθηκε σε ειδικό δυναμόμετρο Electroforce 3550 (ΤΑ Instruments, USA) και έγινε εκτίμηση της αντοχής του σε κάμψη. Οι δυνάμεις εφελκυσμού ξεκινούσαν ως μηδενικές και σταδιακά αυξάνονταν με ταχύτητα 2 mm/min, μέχρι την πρώτη πλαστική παραμόρφωση του συνδετήρα που θεωρήθηκε το σημείο αστοχίας. Με βάση τις μετρήσεις του πειράματος, η ομάδα των συνδετήρων Precise έδειξε σημαντικά μεγαλύτερη αντοχή στην κάμψη (29,633 ± 7,8421 N) σε σχέση με τις ομάδες Proximate ( 16,200 ± 1,1541 N) [P=0.000], Henry Schein (23.383 ± 5,2282 N) [ P=0,011], Weck Visistat (24,329 ± 1,0372 N ) [P= 0,025], Appose (18,133 ± 1,2675 N) [P= 0,000], Manipler (14,067 ± 3,7393 N) [P= 0,000] και Leucoklip (22,288 ± 1,6915 N) [P= 0,002], ενώ δεν εμφάνισε διαφορά συγκριτικά με τις ομάδες Gima (27,483 ± 6,5637 N) [P= 0,370] και Advan (27,283 ± 2,8708 N) [P= 0,327]. Ως εκ τούτου, αποδεικνύεται ότι οι συνδετήρες των ομάδων Precise, Advan και Gima παρουσιάζουν την μεγαλύτερη αντοχή στη κάμψη μετά από άσκηση δυνάμεων εφελκυσμού στο διαμορφωμένο τμήμα τους.

Six staples of each group were mounted on a material testing machine (Electroforce 3550) following configuration. Mechanical properties of staples were evaluated under bending test for the determination of flexural deformation resistance. Results of bending strength to failure were significantly greater for Precise (29,633 ± 7,8421 N) than Proximate ( 16,200 ± 1,1541 N) [P=0.000], Henry Schein (23.383 ± 5,2282 N) [ P=0,011], Weck Visistat (24,329 ± 1,0372 N ) [P= 0,025], Appose (18,133 ± 1,2675 N) [P= 0,000], Manipler (14,067 ± 3,7393 N) [P= 0,000] και Leucoklip (22,288 ± 1,6915 N) [P= 0,002], but was not different from Gima (27,483 ± 6,5637 N) [P= 0,370] and Advan (27,283 ± 2,8708 N) [P= 0,327] staples. The Precise, Advan, and Gima staples showed greater bending strength than the other six staples and were recommended as a secure stapling method used for wound closure.

description: In March of 2012, a company named Aereo began offering a service that provided consumers with an inexpensive way to watch broadcast television programming. Although many consumers embraced Aereo's service, the nation's broadcasters saw Aereo as a threat to their revenue stream. Seeking to put Aereo out of business, the broadcasters filed a copyright infringement suit against Aereo, claiming that Aereo violated their exclusive right to perform copyrighted works publicly. The broadcaster's case eventually made its way to the Supreme Court. The Court, in issuing one of the most covered and debated intellectual property law cases to date, ruled that Aereo violated copyright law. This thesis explains and evaluates the Court's decision and assesses the impact of the decision on the future of copyright law and broadcasting.

The Intergenerational Transmission of Educational Attainment Revisited: The Effects of Socioeconomic Background, Genetic Inheritance, and Cohort
Creators: name: Lin, Meng-Jung
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This research revisits the intertwined social and biological pathways of the intergenerational transmission of educational attainment. By estimating the effects of the whole-genome genetic variants by the continuation ratio logit regressions using 8,251 samples from the Health and Retirement Study (HRS), and considering for socioeconomic status in childhood on education at the same time, I first examine the relative individual impacts of biological and social influences. Then, I consider how parental education shapes the expression of the genetic potential by including moderating effects between the two. Finally, I explore the curvilinear trend of genetic effects over time, and use cohort separated models to investigate the decline in the moderating effects of parental education on educational attainment. The findings suggest the influences are from both genes and family socioeconomic background. Also, the genetic effects were not only negatively moderated by socioeconomic background, but changed curvilinearly over time corresponding to the expansion of higher education in the mid-twentieth century in the U.S. The pattern indicates the educational opportunities equalized at first but saturated after higher education became more accessible. This study furthers the understanding of the social mobility process and provides suggestions for policymakers on education.

They acted pretty much as man and wife: Race, Slavery, and the Borders of Marriage and Family in the Antebellum South
Creators: name: Fruchtman, Daphne
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: During the first decades of the nineteenth century, a small number of wealthy, unmarried planters did something unexpected: they entered into publicly recognized, quasi-marital relationships with enslaved women. In doing so, they not only pushed social boundaries, but specifically sought legal protection and legitimization of their interracial families through a particular legal device: their wills. The pointedly public aspect of these relationships and the varying levels of communal toleration for such openness, however, depart from the conventional scholarly framing of sexual relationships between masters and slaves. Historians have largely--and rightly--conceived of the antebellum South as a place where racial hierarchy was fiercely enforced and where interracial sex between masters and slaves was defined by coercion and rape and acceptable only when shrouded in a culture of secrecy. Indeed, many historians argue that such interracial connections were culturally acceptable in southern communities precisely because they existed outside the realms of both legal and social recognition and thus did not challenge the existing racial hierarchy or the sanctity of the white family. In this thesis, in contrast, I argue that a small but socially significant group of white southern planters complicated this view by living publicly as husband and wife with enslaved black women. Local communities often struggled with how best to reconcile these public acknowledgements of interracial families, but the often successful efforts of those few white men who entered into quasi-marital interracial relationships to secure social and legal recognition for their enslaved families signaled a surprising level of communal toleration for the public airing of interracial intimacy.

description: Back diffusion of trichloroethylene (TCE) from low permeability zones (LPZs), such as clay aquitards, presents a challenge in attainment of site cleanup goals. There is not a clear understanding of the extent by which naturally occurring reactions can attenuate TCE and its daughter products within the LPZs. In this study, a soil coring method that freezes the soil in-situ (a.k.a., cryogenic coring) was utilized to measure depth-discrete distributions of TCE and its volatile reaction products through a TCE-impacted silty clay aquitard. The results were compared with those from adjacent soil cores taken using a conventional coring approach, and found the two coring methods recovered statistically equivalent concentrations of select volatiles across most depths. Biotic reductive dechlorination was found to be the dominant TCE reaction pathway at the site, and concentrations of TCE, cis-1,2-dichloroethylene (DCE), vinyl chloride (VC), ethane, and methane were all compared between the two coring methods. Benefits of the cryogenic coring were better recovery of dispersed sand layers and more variable concentration profiles for TCE, DCE, and VC.

description: We derive the frequency-resolved heat current expression in the linear response regime for a setup comprised of reservoir, interacting central site, and tunneling barrier under the action of a time dependent electrical signal. We exploit the frequency parity properties of response functions to obtain the heat current expression for interacting quantum conductors. Importantly, the corresponding heat formula, valid for arbitrary AC frequencies, can describe photon-assisted heat transport. In particular, we analyze the heat transfer for an interacting multilevel conductor (a carbon nanotube quantum dot) coupled to a single reservoir. We show that the electrothermal admittance can reverse its sign by properly tunning the AC frequency.

description: We introduce to the stellar physics community a method of modelling stellar coronae that can be considered to be an extension of the potential field. In this approach, the magnetic field is coupled to the background atmosphere. The model is magnetohydrostatic (MHS) and is a balance between the Lorentz force, the pressure gradient and gravity. Analytical solutions are possible and we consider a particular class of equilibria in this paper. The model contains two free parameters and the effects of these on both the geometry and topology of the coronal magnetic field are investigated. A demonstration of the approach is given using a magnetogram derived from Zeeman-Doppler imaging of the 0.75 M$_{\odot}$ M-dwarf star GJ 182.

description: Amalgamation is a well-known concept for graph transformations that is used to model synchronised parallelism of rules with shared subrules and corresponding transformations. This concept is especially important for an adequate formalisation of the operational semantics of statecharts and other visual modelling languages, where typed attributed graphs are used for multiple rules with nested application conditions. However, the theory of amalgamation for the double-pushout approach has so far only been developed on a set-theoretical basis for pairs of standard graph rules without any application conditions. For this reason, in the current paper we present the theory of amalgamation for M-adhesive categories, which form a slightly more general framework than (weak) adhesive HLR categories, for a bundle of rules with (nested) application conditions. The two main results are the Complement Rule Theorem, which shows how to construct a minimal complement rule for each subrule, and the Multi-Amalgamation Theorem, which generalises the well-known Parallelism and Amalgamation Theorems to the case of multiple synchronised parallelism. In order to apply the largest amalgamated rule, we use maximal matchings, which are computed according to the actual instance graph. The constructions are illustrated by a small but meaningful running example, while a more complex case study concerning the firing semantics of Petri nets is presented as an introductory example and to provide motivation.
Comparing the Effectiveness of "Individual-loss" and "Family-loss" Messages in Promoting Mammography

description: The study compared the effectiveness of two loss-framed messages, namely, graphics and text therein with individual-loss or family-loss theme, in increasing women's intention to take and talk about mammogram, and level of negative emotions such as sadness. Moderating effect of number of children living in the family, age of the youngest child, and women's marital status was also assessed. Two hundred females were randomly assigned to view either the individual-loss or family-loss message and completed a questionnaire assessing the aforementioned outcomes. After controlling for confounders, multiple regression revealed no significant difference in intention to take or talk about mammogram between the two groups. However, family-loss message induced significantly more sadness compared to the individual-loss message. Multiple regression with interaction indicated that number of children living in the family is a moderator for group effect on intention to talk about mammogram. These results may guide future design of mammogram promotion materials.

description: In this paper a computationally efficient algorithm for continuous blood pressure curve segmentation is presented. It uses only methods in the time domain and can distinguish between systolic, diastolic values and values of calibration steps caused by the continuous blood pressure measuring technique or values of other artefacts. The detection of local extremes, necessary for systolic and diastolic points, is performed with smoothed first and second derivations. An adaptive threshold approach sorts out most of the false extremes, not belonging to the valid blood pressure curve. But only the following plateau detection is suitably reliable to detect local extremes which lie within a calibration step.

description: We performed extensive tests of the accuracy of atmospheric parameter determination for FGK stars based on the spectrum fitting procedure Spectroscopy Made Easy (SME). Our stellar sample consists of 13 objects, including the Sun, in the temperature range 5000--6600~K and metallicity range -1.4 -- +0.4. The analysed stars have the advantage of having parameters derived by interferometry. For each star we use spectra obtained with different spectrographs and different signal-to-noise ratios (S/N). For the fitting we adopted three different sets of constraints and test how the derived parameters depend upon the spectral regions (masks) used in SME. We developed and implemented in SME a new method for estimating uncertainties in the resulting parameters based on fitting residuals, partial derivatives, and data uncertainties. For stars in the 5700--6600 K range the best agreement with the effective temperatures derived by interferometry is achieved when spectrum fitting includes the H$α$ and H$β$ lines, while for cooler stars the choice of the mask does not affect the results. The derived atmospheric parameters do not strongly depend on spectral resolution and S/N of the observations, while the uncertainties in temperature and surface gravity increase with increasing effective temperature, with minima at 50~K in Teff and 0.1~dex in log g, for spectra with S/N=150--200. A NLTE analysis of the TiI/TiII and FeI/FeII ionisation equilibria and abundances determined from the atomic CI (NLTE) and molecular CH species supports the parameters we derived with SME by fitting the observed spectra including the hydrogen lines.

description: Supplementary material for the article: Bressan, P., & Kramer, P. (2021). Most findings obtained with untimed visual Illusions are confounded. Psychological Science, in press. doi: 10.1177/0956797621994268 ABSTRACT Visual illusions have been studied extensively, but their time course has not. Here we show, in a sample of more than 550 people, that unrestricted presentation times—as opposed to presentations lasting only a single second—weaken the Ebbinghaus illusion, strengthen lightness contrast with double increments, and do not alter lightness contrast with double decrements. When presentation time is unrestricted, these illusions are affected in the same way (decrease, increase, no change) by how long observers look at them. Our results imply that differences in illusion magnitude between individuals or groups are confounded with differences in inspection time, no matter whether stimuli are evaluated in matching, adjustment, or untimed comparison tasks. We offer an explanation for why these three illusions progress differently, and we spell out how our findings challenge theories of lightness, theories of global-local processing, and the interpretation of all research that has investigated visual illusions, or used them as tools, without considering inspection time.

description: The reflectance spectrum of the species in a hyperspectral data can be modelled as an n-dimensional vector. The spectral angle mapper computes the angle between the vectors which is used to discriminate the species. The spectral information divergence models the data as a probability distribution so that the spectral variability between the bands can be extracted using the stochastic measures. The hybrid approach of spectral angle mapper and spectral information divergence is found to be better discriminator than spectral angle mapper or spectral information divergence alone. The spectral correlation angle is computed as a cosine of the angle of the Pearsonian correlation coefficient between the vectors. The spectral correlation angle is a better measure than the spectral angle mapper as it considers only standardized values of the vectors rather than the absolute values of the vector. In the present paper a new hybrid measure is proposed which is based on the spectral correlation angle and the spectral information divergence. The proposed method has been compared with the hybrid approach of spectral information divergence and spectral angle mapper for discrimination of crops belonging to Vigna species using measures like relative spectral discriminatory power, relative discriminatory probability and relative discriminatory entropy in different spectral regions. Experimental results using the laboratory spectra show that the proposed method gives higher relative discriminatory power in 400nm-700nm spectral region.

description: Stochastic chains represent a wide and key variety of phenomena in many branches of science within the context of Information Theory and Thermodynamics. They are typically approached by a sequence of independent events or by a memoryless Markov process. Here, we demonstrate that when memory is introduced, the statistics of the system depends on the mechanism by which objects or symbols are assembled, even in the slow dynamics limit wherein friction can be neglected. To analyse these systems, we introduce a sequence-dependent partition function, investigate its properties and compare it to the standard normalization defined by the statistical physics of ensembles. Then, we study the behaviour of the entropy and the internal energy in this intrinsic, directional chains finding that they vary around their thermally-induced equilibrium analogues due to memory effects. We anticipate that our results are necessary to interpret configurational order and information transfer in many molecular systems within Materials Science, Biophysics, Communication and Engineering.

description: Despite decades of observations of the solar cycle, the underlying mechanism is not entirely understood. Observation of activity cycles in stars that evolved further from the main sequence, such as red giants, may help put additional constraints on the dynamo models. The surface magnetic fields sustained by the dynamo are known to affect the oscillations inside the stars. Observations of the Sun have shown that the oscillation frequencies change in phase while the mode amplitudes change out of phase with the solar cycle. Similar observations have been made on other solar-type stars using asteroseismology to detect activity cycles. Using the long-cadence photometric data from Kepler, we analysed the long-term trends in the global asteroseismic parameters of 16,094 red giants with solar-like oscillations. We identified stars displaying significant variation in these parameters by studying the long-term trends and computed their mean frequency for each Kepler quarter using a cross-correlation method. We estimated the error bars of these shifts using Monte Carlo simulations. The expected frequency shifts for red giants were predicted to be a few μHz, but our results show the shifts to be around 1/100-1/10th of a μHz. Additionally, we found that the estimated error bars are significantly larger than the quarterly variations in frequency shifts, making it challenging to detect activity cycles in red giants.
Is mindfulness a non-judgmental stance?
Creators: name: Adair, Kathryn Carrie

description: Mindfulness has been defined as being comprised by 1) present moment attention and awareness, and 2) a stance of non-judgment towards experience. To date, scant basic research has been conducted to test whether this second aspect, non-judgment, is indeed related to mindfulness at automatic levels of consciousness. Theoretical work has posited that as a non-judgmental stance, mindfulness allows for stimuli to be viewed more objectively, or empirically. Thus, we hypothesized that individuals high in state and trait mindfulness would exhibit a reduction in automatic judgments. Three studies were conducted to assess the role of mindfulness across a variety of measures of judgment (i.e., personally motivated perception, implicit and explicit attitudes, and affective reactivity to various photographs as measured by facial EMG). Across these studies we found evidence that mindfulness is related to attenuated bias in judgments and behaviors, however mindfulness also appears related to greater positive affective reactivity.
Cognitive Performance in Pediatric Bipolar Disorder

description: Bipolar disorder is an increasingly popular diagnosis in youth, and there has been a corresponding increase in interest in investigating neuropsychological and cognitive profiles in children and adolescents diagnosed with bipolar disorder. The extant literature reveals that youth with bipolar disorder frequently show deficits in the areas of executive functioning, short term memory, learning and long term memory, sustained attention, processing speed, intelligence testing, and academic functioning. This study examined cognitive performance and academic achievement in inpatient youth with bipolar disorder versus comparison inpatient youth with other psychiatric disorders. No differences were found on measures of cognitive ability, visual-motor integration, or academic achievement. Prior findings of cognitive deficits may be due to comparison to healthy controls, not deficits specific to bipolar disorder. When compared with other psychiatrically impaired youth, inpatient children and adolescents do not show these deficits.

description: The ALICE Collaboration has studied the inclusive J/$ψ$ and $ψ(\mathrm{2S})$ production in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV, at the CERN LHC. The J/$ψ$ measurement is performed in the $μ^{+}μ^{-}$ and in the $e^{+}e^{-}$ decay channels, down to zero $p_{\mathrm{T}}$. The results are in fair agreement with theoretical predictions. The $ψ(\mathrm{2S})$ measurement has also been performed. In particular, a smaller $ψ(\mathrm{2S})$ nuclear modification factor, with respect to the J$/ψ$ one, has been observed.
