description: The frequency of the breathing mode of a classical two dimensional Fermi gas in a harmonic confinement is fixed by the scale invariance of the Hamiltonian. Scale invariance is broken on the quantum mechanical level by introducing the two dimensional scattering length as a regulator. This is an example of a quantum anomaly in the field of ultracold atoms and leads to a shift of the frequency of the collective breathing mode of the cloud. In this work, we study this anomalous frequency shift for a two component Fermi gas in the strongly interacting regime. We measure significant shifts away from the scale invariant result that depend strongly on both interactions and temperature. We find qualitative agreement with theoretical calculations at zero temperature.

description: We investigate the effect of mobile polymer brushes on proteins embedded in biological membranes by employing both Asakura-Oosawa type of theoretical model and coarse-grained molecular dynamics simulations. The brush polymer-induced depletion attraction between proteins changes non-monotonically with the size of brush. The depletion interaction, which is determined by the ratio of protein size to the grafting distance between brush polymers, increases linearly with brush size as long as the polymer brush height is shorter than the protein size. When the brush height exceeds the protein size, however, the depletion attraction among proteins is slightly reduced. We also explore the possibility of brush polymer-induced assembly of a large protein cluster, which can be related to one of many molecular mechanisms underlying recent experimental observations of integrin nanocluster formation and signaling.

description: We calculate the leading-order matrix element for the decay $B \to K^* γ$ in the quenched approximation of lattice QCD on a $24^3 \times 48$ lattice at $β=6.2$, using an O(a)-improved fermion action. Extrapolating the quark masses to their physical values we obtain an on-shell form factor of $T_1(q^2=0)=0.15+12-14$, where the errors quoted are purely statistical. We find $T_1$ is approximately independent of the spectator quark mass and extract $T_1(q^2=0)=0.15+5-4$ if this independence is assumed. We compare this with the same form factor derived (in the Standard Model) from the CLEO experimental branching ratio of $BR(B \to K^* γ) = (4.5 \pm 1.5 \pm 0.9) \times 10^{-5}$ and find the results to be consistent within statistical errors.

description: The automatic detection of software vulnerabilities is an important research problem. However, existing solutions to this problem rely on human experts to define features and often miss many vulnerabilities (i.e., incurring high false negative rate). In this paper, we initiate the study of using deep learning-based vulnerability detection to relieve human experts from the tedious and subjective task of manually defining features. Since deep learning is motivated to deal with problems that are very different from the problem of vulnerability detection, we need some guiding principles for applying deep learning to vulnerability detection. In particular, we need to find representations of software programs that are suitable for deep learning. For this purpose, we propose using code gadgets to represent programs and then transform them into vectors, where a code gadget is a number of (not necessarily consecutive) lines of code that are semantically related to each other. This leads to the design and implementation of a deep learning-based vulnerability detection system, called Vulnerability Deep Pecker (VulDeePecker). In order to evaluate VulDeePecker, we present the first vulnerability dataset for deep learning approaches. Experimental results show that VulDeePecker can achieve much fewer false negatives (with reasonable false positives) than other approaches. We further apply VulDeePecker to 3 software products (namely Xen, Seamonkey, and Libav) and detect 4 vulnerabilities, which are not reported in the National Vulnerability Database but were "silently" patched by the vendors when releasing later versions of these products; in contrast, these vulnerabilities are almost entirely missed by the other vulnerability detection systems we experimented with.
Flavourful $Z'$ portal for vector-like neutrino Dark Matter and $R_{K^{(*)}}$

description: We discuss a flavourful $Z'$ portal model with a coupling to fourth-family singlet Dirac neutrino dark matter. In the absence of mixing, the $Z'$ is fermiophobic, having no couplings to the three chiral families, but does couple to a fourth vector-like family. Due to mixing effects, the $Z'$ gets induced couplings to second family left-handed lepton doublets and third family left-handed quark doublets. This model can simultaneously account for the measured $B$-decay ratios $R_{K}$ and $R_{K^*}$ and for the observed relic abundance of dark matter. We identify the parameter space where this explanation is consistent with existing experimental constraints from dark matter direct and indirect detection, LHC searches, and precision measurements of flavour mixing and neutrino processes.

description: Elliptical galaxies comprise primarily old stars, which collectively generate a long-lasting feedback via stellar mass-loss and Type Ia SNe. This feedback can be traced by X-ray-emitting hot gas in and around such galaxies, in which little cool gas is typically present. However, the X-ray-inferred mass, energy, and metal abundance of the hot gas are often found to be far less than what are expected from the feedback, particularly in so-called low LX/LB ellipticals. This “missing” stellar feedback is presumably lost in galaxy-wide outflows, which can play an essential role in galaxy evolution (e.g., explaining the observed color bi-modality of galaxies). We are developing a model that can be used to properly interpret the X-ray data and to extract key information about the dynamics of the feedback and its interplay with galactic environment.
Predictors of Behavioral and Relationship Outcomes During Mutual Self-Disclosure: Implications for Dyadic Peer Support Interventions

description: Despite the popular use of peer support interventions to improve the interpersonal functioning of patients with mental illness, research into the effectiveness of such programs has returned mixed results. In order to better understand potential moderators of these interventions’ effectiveness, the present study involved the random pairing of two same-sex strangers who took turns engaging in mutual self-disclosure on two separate occasions, separated by one week. A total of 51 same-sex pairs of college students were enrolled in this study. Our aim was to examine whether social competence and existing levels of social support predicted engagement in the interactions, specifically self-disclosure and support provision. Although both social competence and social support predicted engagement in the interaction, social competence appeared to be the more robust predictor. Dyadic data analyses revealed that providing emotional and instrumental support to a partner predicted an increase in one’s liking for and plans to communicate with this partner. The association between emotional support and relationship outcomes was stronger among males than females, whereas the association between instrumental support and relationship outcomes was stronger for females than males.

Thermodynamic properties of Holstein polarons and the effects of disorder

Year: 2007
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The ground state and finite temperature properties of polarons are studied considering a two-site and a four-site Holstein model by exact diagonalization of the Hamiltonian. The kinetic energy, Drude weight, correlation functions involving charge and lattice deformations, and the specific heat have been evaluated as a function of electron-phonon (e-ph) coupling strength and temperature. The effects of site diagonal disorder on the above properties have been investigated. The disorder is found to suppress the kinetic energy and the Drude weight, reduces the spatial extension of the polaron, and makes the large-to-small polaron crossover smoother. Increasing temperature also plays similar role. For strong coupling the kinetic energy arises mainly from the incoherent hopping processes owing to the motion of electrons within the polaron and is almost independent of the disorder strength. From the coherent and incoherent contributions to the kinetic energy, the temperature above which the incoherent part dominates is determined as a function of e-ph coupling strength.

description: Non-local correlations that obey the no-signalling principle contain intrinsic randomness. In particular, for a specific Bell experiment, one can derive relations between the amount of randomness produced, as quantified by the min-entropy of the output data, and its associated violation of a Bell inequality. In practice, due to finite sampling, certifying randomness requires the development of statistical tools to lower-bound the min-entropy of the data as a function of the estimated Bell violation. The quality of such bounds relies on the choice of certificate, i.e., the Bell inequality whose violation is estimated. In this work, we propose a method for choosing efficiently such a certificate. It requires sacrificing a part of the output data in order to estimate the underlying correlations. Regularising this estimate then allows one to find a Bell inequality that is well suited for certifying practical randomness from these specific correlations. We then study the effects of various parameters on the obtained min-entropy bound and explain how to tune them in a favourable way. Lastly, we carry out several numerical simulations of a Bell experiment to show the efficiency of our method: we nearly always obtain higher min-entropy rates than when we use a pre-established Bell inequality, namely the Clauser-Horne-Shimony-Holt inequality.

Predictive Patterns of Sex Trafficking Online
Creators: name: Kennedy, Emily
Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: History

description: In the past 10-15 years, the internet has become a popular tool for sex traffickers to advertise and sell their victims. For instance, there are thousands of posts each month selling sex on the common classifieds website Backpage.com, some of which may be cases of sex trafficking. I extracted this publicly available data from the U.S. cities represented on Backpage.com. I then used software developed at Carnegie Mellon’s Auton Lab to find out if it is possible to detect patterns emerging from the data available in sex ads, such as patterns of travel that traffickers may use. To help identify which posts are more likely to be cases of trafficking, I relied on guidance from law enforcement experts. The research in this paper shows that it is in theory possible to track the movement of similar posts—and therefore, similar pimps or victims—across the country over time. With further development and refinement, the techniques demonstrated in this thesis could become the foundation for a valuable tool for law enforcement to use to prosecute traffickers and rescue victims.

description: In the theory of conditional sets, many classical theorems from areas such as functional analysis, probability theory or measure theory are lifted to a conditional framework, often to be applied in areas such as mathematical economics or optimization. The frequent experience that such theorems can be proved by `conditionalizations' of the classical proofs suggests that a general transfer principle is in the background, and that formulating and proving such a transfer principle would yield a wealth of useful further conditional versions of classical results, in addition to providing a uniform approach to the results already known. In this paper, we formulate and prove such a transfer principle based on second-order arithmetic, which, by the results of reverse mathematics, suffices for the bulk of classical mathematics, including real analysis, measure theory and countable algebra, and excluding only more remote realms like category theory, set-theoretical topology or uncountable set theory, see e.g. the introduction of \cite{simpson2009subsystems}.This transfer principle is then employed to give short and easy proofs of conditional versions of central results in various areas of mathematics, including theorems which have not been proven by hand previously such as Peano existence theorem, Urysohn's lemma and the Markov-Kakutani fixed point theorem. Moreover, we compare the interpretation of certain structures in a conditional model with their meaning in a standard model.

Predicting Undergraduate Passions: An Analysis of Major Migration at Carnegie Mellon

subject: FOS: Psychology

description: With six undergraduate colleges, Carnegie Mellon University offers a plethora of choices for primary and additional majors, as well as interdisciplinary programs. Such variety has the potential to assist or hinder students’ undergraduate careers, dependent upon how often their interests change, and how quickly they find their fit at CMU. This paper discusses the potential reasons behind major migration at CMU, and whether or not we are able to predict the likelihood that a given student will switch their major before graduation. By looking at the Class of 2015 cohort over twelve semesters, we run linear discriminant analysis and logistic regression on a representative sample of 1136 students. Through these methods, we determine that predicting student migration yields high error rates when working with a small subset of binary demographic variables, yet there is potential for a stronger prediction algorithm with more data and more robust variables such as cumulative QPA and socio-economic status. We also focus on the predictive capability of Dietrich College first-year survey data, and find that additional variables such as the number of interests incoming students have and which interests become their graduating majors are significant in classifying potential migrators. In both cohort and survey data, we find that the time it takes to initially declare is an important variable in determining whether or not a student will switch majors. The likelihood of switching is greatest if one initially declares in the spring of their first year, and drops off thereafter. This suggests that advisors should work closely with students to determine if it is the right time to declare. Declaring early can give students access to classes within the primary department, and declaring too late could leave students stuck in a major they are not truly passionate about.

description: In der Türkei besteht für jeden gesunden, männlichen Bürger zwischen 20 und 41 Jahren die Wehrpflicht. Homosexuelle Männer können sich allerdings um einen sogenannten „Rotten Report“ und damit um eine Befreiung von der Wehrpflicht bewerben. Dieser Aufsatz beschäftigt sich mit der Frage, wie das türkische Militär hegemoniale Männlichkeit und traditionelle Geschlechterrollen durch die Prozeduren der ‚Rotten Reports‘ (re)produziert. Dafür werden Theorien der militärischen Sozialisation (Kliche 2004), der hegemonialen Männlichkeit (Connell 1995) und der Gender-Performativität (Butler 1990) angewendet. Um einen ‚Rotten Report‘ zu erhalten, müssen sich die männlichen Bewerber erniedrigenden Untersuchungen unterziehen. Die Prozedur der ,Rotten Reports‘ führt dazu, dass die Bewerber sich bemühen, ihre Genderperformanz an das Bild des ,verweiblichten‘ homosexuellen Mannes anzupassen, um in den Augen des Militärs als homosexuell und folglich als ,Gefahr‘ und ,ungeeignet‘ für den Militärdienst eingestuft zu werden. Durch diesen Ausschluss von Homosexuellen aus dem Militärdienst produziert das Militär hegemoniale Männlichkeit. Diese Genderperformanz trägt wiederum zur Aufrechterhaltung der traditionellen Geschlechterrollen bei. Auf der Grundlage einer Literaturanalyse von Primär- und Sekundärquellen, darunter wissenschaftlichen Texte, die auf Interviews mit Betroffenen basieren, Befragungen, Artikel und Blogs von türkischen LGBTI-Organisationen, wird die Frage empirisch beantwortet.

description: In bosonic gases at thermal equilibrium, an external quadratic drive can induce a Bose-Einstein condensation described by the Ising transition, as a consequence of the explicitly broken U(1) phase rotation symmetry down to $\mathbb{Z}_2$. However, in physical realizations such as exciton-polaritons and nonlinear photonic lattices, thermal equilibrium is lost and the state is rather determined by a balance between losses and external drive. A fundamental question is then how nonequilibrium fluctuations affect this transition. Here, we show that in a two-dimensional driven-dissipative Bose system the Ising phase is suppressed and replaced by a nonequilibrium phase featuring Kardar-Parisi-Zhang (KPZ) physics. Its emergence is rooted in a U(1)-symmetry restoration mechanism enabled by the strong fluctuations in reduced dimensionality. Moreover, we show that the presence of the quadratic drive term enhances the visibility of the KPZ scaling, compared to two-dimensional U(1)-symmetric gases, where it has remained so far elusive.

description: We consider a U(1) gauge theory, minimally coupled to a massless Dirac field, where a higher-derivative term is added to the pure gauge sector, as in the Lee-Wick models. We find that this term can trigger chiral symmetry breaking at low energy in the weak coupling regime. Then, the fermion field acquires a mass that turns out to be a function of both the energy scale associated to the higher-derivative term and the gauge coupling. The dependence of the fermion mass on the gauge coupling is non-perturbative. Extensions to SU(N) gauge theories and fermion-scalar interactions are also analyzed, as well as to theories with massive gauge fields. A few implications of these results in the framework of quark-mass generation are discussed.

description: Autonomous lifelong development and learning is a fundamental capability of humans, differentiating them from current deep learning systems. However, other branches of artificial intelligence have designed crucial ingredients towards autonomous learning: curiosity and intrinsic motivation, social learning and natural interaction with peers, and embodiment. These mechanisms guide exploration and autonomous choice of goals, and integrating them with deep learning opens stimulating perspectives. Deep learning (DL) approaches made great advances in artificial intelligence, but are still far away from human learning. As argued convincingly by Lake et al., differences include human capabilities to learn causal models of the world from very little data, leveraging compositional representations and priors like intuitive physics and psychology. However, there are other fundamental differences between current DL systems and human learning, as well as technical ingredients to fill this gap, that are either superficially, or not adequately, discussed by Lake et al. These fundamental mechanisms relate to autonomous development and learning. They are bound to play a central role in artificial intelligence in the future. Current DL systems require engineers to manually specify a task-specific objective function for every new task, and learn through off-line processing of large training databases. On the contrary, humans learn autonomously open-ended repertoires of skills, deciding for themselves which goals to pursue or value, and which skills to explore, driven by intrinsic motivation/curiosity and social learning through natural interaction with peers. Such learning processes are incremental, online, and progressive. Human child development involves a progressive increase of complexity in a curriculum of learning where skills are explored, acquired, and built on each other, through particular ordering and timing. Finally, human learning happens in the physical world, and through bodily and physical experimentation, under severe constraints on energy, time, and computational resources. In the two last decades, the field of Developmental and Cognitive Robotics (Cangelosi and Schlesinger, 2015, Asada et al., 2009), in strong interaction with developmental psychology and neuroscience, has achieved significant advances in computational

description: In recent years, PowerPoint presentations have become the medium of choice for high school and college educators. Research on images in these presentations has determined that relevant diagrams and graphics improve learning in science and engineering fields; however, there has been little research on images in the humanities, where diagrams are less common. This study first surveyed college students to determine which images are considered informative and which are considered decorative. Using these results, I presented a new group of participants with humanities content accompanied by different image types. Participants then took a quiz on the content. Quiz results seem to indicate that the images deemed “informative” and text-only slides aided retention the most. A surprising finding was how often SmartArt and images accidentally contradicted the slide’s main ideas and hurt retention. This finding could help educators and presenters avoid using contradictory or backfiring visuals. This report concludes with a recommendation for a usability test that presenters can use to assess the efficacy of their slide visuals.

description: This is an idea that took a tremendous amount of outlining before I was able to get anything down on paper initially, aside from the first few pages. I would pitch it as a modern-day dyssey, but revolving more around "bad guys".

As a whole, I tried to represent virtually all the main
characters seen in the original epic poem. I chose to replace the actual Gods by incorporating the media as a character that runs throughout the series. They will advance the plot, alert characters of important events, and inspire the story in a number of other ways as well. Without a doubt, the narrative structure on this is the most complicated I have attempted to date. The use of four different storylines in the first episode provides for not only more tension for the audience, but I believe that it was also the best way to illustrate the idea of The Odyssey coming to life in an entirely different way.

description: We report on computer simulations and analytic theory to provide a self-consistent understanding of the role of the reconnection electric field, which extends substantially beyond the simple change of magnetic connections. Rather, we find that the reconnection electric field is essential to maintaining the current density in the diffusion region, which would otherwise be dissipated by a set of processes. Natural candidates for current dissipation are the average convection of current carriers away from the reconnection region by the outflow of accelerated particles, or the average rotation of the current density by the magnetic field reversal in the vicinity. Instead, we show here that the current dissipation is the result of thermal effects, underlying the statistical interaction of current-carrying particles with the adjacent magnetic field. We find that this interaction serves to redirect the directed acceleration of the reconnection electric field to thermal motion. This thermalization manifests itself in form of quasi-viscous terms in the thermal energy balance of the current layer. These quasi-viscous terms act to increase the average thermal energy. Our predictions regarding current and thermal energy balance are readily amenable to exploration in the laboratory or by satellite missions, in particular, by NASAs Magnetospheric Multiscale mission.

description: A lattice calculation of the form factors that determine the ``hadronization ratios'', such as $R_{K^*}$ and $R_ϕ$, where $R_{K^*} \equiv [Γ($B \to K^* γ$)/Γ(b \to s γ)]$, is presented in the quenched approximation. Lattice data shows strong evidence for the scaling law suggested by heavy quark symmetry for one of the form factors ({\it i.e.}\ $T_2$). The data also gives strong support for the simple pole ansatz for the $q^2$ dependence of $T_2$ in the range of available $q^2$. We thus find $T_2(0) = .10 \pm.01\pm.03$ yielding $R_{K^*} =(6.0\pm1.2\pm3.4)\%$; we also find $R_ϕ=(6.6\pm1.3\pm3.7)\%$.
description: 13 pages (Latex), Wash. U. HEP/93-35. (Revised: we have corrected and extended the table of phenomenological results for $R_{K^*}$, eliminated a discussion of $V_{ts}/V_{cb}$ which contained too many unstated assumptions, and made a few other minor corrections.)

Spinodal de-wetting of light liquids on graphene

description: We demonstrate theoretically the possibility of spinodal de-wetting in heterostructures made of light--atom liquids (hydrogen, helium, and nitrogen) deposited on suspended graphene. Extending our theory of film growth on two-dimensional materials to include analysis of surface instabilities via the hydrodynamic Cahn--Hilliard-type equation, we characterize in detail the resulting spinodal de-wetting patterns. Both linear stability analysis and advanced computational treatment of the surface hydrodynamics show micron-sized (generally material and atom dependent) patterns of "dry" regions. The physical reason for the development of such instabilities on graphene can be traced back to the inherently weak van der Waals interactions between atomically thin materials and atoms in the liquid. Similar phenomena occur in doped graphene and other two-dimensional materials, such as monolayer dichalcogenides. Thus two-dimensional materials represent a universal theoretical and technological platform for studies of spinodal de-wetting.

description: We study a $U(N)\times U(N)$ symmetric scalar field model in four and three dimensions. First, using our data in four dimensions in the weak coupling region, we demonstrate explicitly that the observed first order phase transition is induced by quantum fluctuations. Next, based on the renormalization group and our new simulation results in three dimensions we argue that even if the $U_A(1)$ symmetry is restored below the critical temperature the QCD finite temperature chiral phase transition for two flavor could be extremely weak first order.

Perceptions of Experienced and Expressed Happiness

subject: FOS: Psychology

description: It was hypothesized that expressions of happiness within same-race dyads
(consisting of two Caucasian students or two Asian students) would be perceived as more
authentic than would expressions of happiness within mixed race dyads. The rationale
was that expressions of happiness received from a member of a different race might be
perceived as driven by politeness and a desire not to appear racially biased. Thus they
might be discounted as evidence of true happiness. Such discounting was not expected to
occur when expressions of happiness were received from a same race partner. These
hypotheses were tested in two studies. In the first study, participants read a scripted
interaction between pairs of Asian students, pairs of Caucasian students, or mixed pairs
and judged the extent to which expressed happiness likely reflected true happiness. In a
second study, participants actually participated in a five-minute videotaped interaction
with a participant of the same race or with a participant of a different race. Later, in
private, they indicated how much happiness they and their partner expressed, how much
happiness they actually experienced in the interaction, and how much happiness they
believed their partner experienced. Neither study yielded clear support for the original
hypotheses. However, the second study did yield some compelling results relevant to
perceptions of expressed and felt happiness. Specifically, participants consistently
reported that: a) They, themselves, felt more happiness than they expressed (i.e. they
suppressed happiness); b) In contrast, they reported that their partner expressed more
happiness than that partner actually felt (i.e. they believed the partner was exaggerating
happiness); and c) Whereas these results were evident for both Asians and Caucasians,
there was a significant interaction such that these tendencies were more pronounced

description: People in the United States are gaining weight at a rate higher than in the past. Because the eating habits people develop in college are similar to the eating habits people will have for the rest of their lives it is imperative that researchers understand more about why people gain weight in college. The purpose of the proposed survey-based study was to explore the relationship between perceived stress, perceived social support, and depression as it connects to weight changes and food choices in college students who are nonnal and abnonnal eaters. We hypothesized that those who are stressed, depressed, and lacking in social support would eat differently and have higher body mass indexes than people who do not suffer from these symptoms. Results from this study indicated that there was a relationship between perceived stress, perceived social support, and depression and this was correlated with restrained eating patterns. There was also a positive correlation found between perceived stress and soda consumption. A correlation was not shown between abnonnal eating patterns and overall weight. Implications from this study are that college food service providers should provide healthy, easy to eat food.

description: Central Compact Objects (CCOs) are a handful of soft X-ray sources located close to the centers of Supernova Remnants and supposed to be young, radio-quiet Isolated Neutron Stars (INSs). A clear understanding of their physics would be crucial in order to complete our view of the birth properties of INSs. We will review the phenomenologies of CCOs, underlining the most important, recent results, and we will discuss the possible relationships of such sources with other classes of INSs.
