description: The hypotheses put forth in this pre-registration are an extension to previous hypotheses that were pre-registered on the Open Science Framework (OSF). More specifically, in an initial pre-registration, we advanced two hypotheses: (1) we expected people who were in a relationship and who reported more COVID-related stressors— specifically financial strain, social isolation, and stress— to report poorer relationship quality and greater conflict; though (2) we expected this effect to be moderated by perceived partner responsiveness, such that those who perceived their partner to be responsive to their needs would be buffered against the detriments of COVID-related stressors on relationship quality and conflict. The initial pre-registration advanced and proposed testing the predictions using the data from time 1 (T1) of the Love in the Time of COVID study. We now seek to extend the initial pre-registration to assess the effects of COVID-related stressors (i.e., social isolation, social disconnection, worry, financial strain, and stress) on relationship quality overtime (examining the effects across six time points, each approximately two weeks apart).

description: In two dimensions strongly interacting bosons in a magnetic field can realize a bosonic integer quantum Hall state, the simplest two dimensional example of a symmetry protected topological phase. We propose a realistic implementation of this phase using an optical flux lattice. Through exact diagonalization calculations, we show that the system exhibits a clear bulk gap and the topological signature of the bosonic integer quantum Hall state. In particular, the calculation of the many-body Chern number leads to a quantized Hall conductance in agreement with the analytical predictions. We also study the stability of the phase with respect to some of the experimentally relevant parameters.

Partitioning Algorithms for Improving Efficiency of Topic Modeling Parallelization
Creators: name: Tran, Hung Nghiep

Publisher: name: arXiv
Year: 2015
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)
subject: FOS: Computer and information sciences

description: Topic modeling is a very powerful technique in data analysis and data mining but it is generally slow. Many parallelization approaches have been proposed to speed up the learning process. However, they are usually not very efficient because of the many kinds of overhead, especially the load-balancing problem. We address this problem by proposing three partitioning algorithms, which either run more quickly or achieve better load balance than current partitioning algorithms. These algorithms can easily be extended to improve parallelization efficiency on other topic models similar to LDA, e.g., Bag of Timestamps, which is an extension of LDA with time information. We evaluate these algorithms on two popular datasets, NIPS and NYTimes. We also build a dataset containing over 1,000,000 scientific publications in the computer science domain from 1951 to 2010 to experiment with Bag of Timestamps parallelization, which we design to demonstrate the proposed algorithms' extensibility. The results strongly confirm the advantages of these algorithms.

description: This study investigated the extended Holstein--Hubbard model at half-filling as a model for describing interplay of the electron-electron and electron-phonon couplings. When the electron-phonon and nearest-neighbor electron-electron interactions are strong, we prove the existence of long-range charge order at sufficiently low temperature in three or more dimensions. As a result, we rigorously justify the phase competition between the antiferromagnetic and charge orders.

description: Relying on an effective-string approach in which glueballs --- bound states of pure Yang-Mills theory --- are modelled by closed strings, we give arguments suggesting that anyonic glueballs, \textit{i.e.} glueballs with arbitrary spin, may exist in $(2+1)$-$\,$dimensional Yang-Mills theory. We then focus on the large$\,$-$N_c$ limit of $SU$($N_c$) Yang-Mills theory and show that our model leads to a mass spectrum in good agreement with lattice data in the scalar sector, while it predicts the masses and spins of anyonic glueball states.

Looking for lepton flavour violation in supersymmetry at the LHC

description: We consider models of supersymmetry which can incorporate sizeable mixing between different generations of sfermions. While the mixing is constrained by the non-observation of various flavour changing neutral current (FCNC) processes, there exist regions of SUSY parameter space where the effects of such mixing can be probed at colliders. In this work, we explore this possibility by focussing on the slepton sector. The sleptons are produced through cascade decays in direct neutralino-chargino ($χ_2^0χ_1^\pm$) pair production at the LHC. The final state is characterized by 3 leptons and missing energy. We probe the lepton flavour violating (LFV) vertex originating from $χ_2^0$ decay and identify a distinct and unambiguous combination of the tri-lepton final state which include a lepton pair with same flavour and same sign (SFSS) in addition to a pair with opposite flavour and opposite sign (OFOS). This combination of tri-lepton final state containing both OFOS and SFSS pairs, can not only suppress the SM background but can also differentiate the flavour violating decays of $χ_2^0$ from its corresponding flavour conserving decays. We present results for various signal benchmark points taking into account background contributions assuming two luminosity options (100 fb$^{-1}$ and 1000 fb$^{-1}$) for LHC Run 2 experiment.

description: To measure the stellar and orbital properties of the metal-poor RS CVn binary o Draconis (o Dra), we directly detect the companion using interferometric observations obtained with the Michigan InfraRed Combiner at Georgia State University's Center for High Angular Resolution Astronomy (CHARA) Array. The H-band flux ratio between the primary and secondary stars is the highest confirmed flux ratio (370 +/- 40) observed with long-baseline optical interferometry. These detections are combined with radial velocity data of both the primary and secondary stars, including new data obtained with the Tillinghast Reflector Echelle Spectrograph on the Tillinghast Reflector at the Fred Lawrence Whipple Observatory and the 2-m Tennessee State University Automated Spectroscopic Telescope at Fairborn Observatory. We determine an orbit from which we find model-independent masses and ages of the components (M_A = 1.35 +\- 0.05 M_Sun, M_B = 0.99 +\- 0.02 M_Sun, system age = 3.0 -\+ 0.5 Gyr). An average of a 23-year light curve of o Dra from the Tennessee State University Automated Photometric Telescope folded over the orbital period newly reveals eclipses and the quasi-sinusoidal signature of ellipsoidal variations. The modeled light curve for our system's stellar and orbital parameters confirm these ellipsoidal variations due to the primary star partially filling its Roche lobe potential, suggesting most of the photometric variations are not due to stellar activity (starspots). Measuring gravity darkening from the average light curve gives a best-fit of beta = 0.07 +\- 0.03, a value consistent with conventional theory for convective envelope stars. The primary star also exhibits an anomalously short rotation period, which, when taken with other system parameters, suggests the star likely engulfed a low-mass companion that had recently spun-up the star.

description: We analyze the exact exponential decay rate of the expected amount of information leaked to the wiretapper in Wyner's wiretap channel setting using wiretap channel codes constructed from both i.i.d. and constant-composition random codes. Our analysis for those sampled from i.i.d. random coding ensemble shows that the previously-known achievable secrecy exponent using this ensemble is indeed the exact exponent for an average code in the ensemble. Furthermore, our analysis on wiretap channel codes constructed from the ensemble of constant-composition random codes leads to an exponent which, in addition to being the exact exponent for an average code, is larger than the achievable secrecy exponent that has been established so far in the literature for this ensemble (which in turn was known to be smaller than that achievable by wiretap channel codes sampled from i.i.d. random coding ensemble). We show examples where the exact secrecy exponent for the wiretap channel codes constructed from random constant-composition codes is larger than that of those constructed from i.i.d. random codes and examples where the exact secrecy exponent for the wiretap channel codes constructed from i.i.d. random codes is larger than that of those constructed from constant-composition random codes. We, hence, conclude that, unlike the error correction problem, there is no general ordering between the two random coding ensembles in terms of their secrecy exponent.

description: Given their importance in shaping social networks and determining how information or diseases propagate in a population, human interactions are the subject of many data collection efforts. To this aim, different methods are commonly used, from diaries and surveys to wearable sensors. These methods show advantages and limitations but are rarely compared in a given setting. As surveys targeting friendship relations might suffer less from memory biases than contact diaries, it is also interesting to explore how daily contact patterns compare with friendship relations and with online social links. Here we make progresses in these directions by leveraging data from a French high school: face-to-face contacts measured by two concurrent methods, sensors and diaries; self-reported friendship surveys; Facebook links. We compare the data sets and find that most short contacts are not reported in diaries while long contacts have larger reporting probability, with a general tendency to overestimate durations. Measured contacts corresponding to reported friendship can have durations of any length but all long contacts correspond to reported friendships. Online links not associated to reported friendships correspond to short face-to-face contacts, highlighting the different nature of reported friendships and online links. Diaries and surveys suffer from a low sampling rate, showing the higher acceptability of sensor-based platform. Despite the biases, we found that the overall structure of the contact network, i.e., the mixing patterns between classes, is correctly captured by both self-reported contacts and friendships networks. Overall, diaries and surveys tend to yield a correct picture of the structural organization of the contact network, albeit with much less links, and give access to a sort of backbone of the contact network corresponding to the strongest links in terms of cumulative durations.
The Right Direction for North Carolina and Paid Maternity Leave
Creators: name: Said, Kristen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The United States is the only industrialized nation in the world that does not offer some form of paid maternity leave. The Family and Medical Leave Act (FMLA) guarantees unpaid job-protected leave to select qualifying individuals. To date, only four states have implemented their own paid family leave programs through an expansion of existing temporary disability insurance (TDI) program. Paid maternity leave leads to decreased in infant deaths and post-partum depression as well as increased breastfeeding, among other benefits. These benefits can be gained with minimal to no negative impact on employers. North Carolina should be the first state without an existing TDI program to institute a job-protected paid family leave program.

Atomic Motion from the Mean Square Displacement in a Monatomic Liquid

description: V-T theory is constructed in the many-body Hamiltonian formulation, and differs at the foundation from current liquid dynamics theories. In V-T theory the liquid atomic motion consists of two contributions, normal mode vibrations in a single representative potential energy valley, and transits, which carry the system across boundaries between valleys. The mean square displacement time correlation function (the MSD) is a direct measure of the atomic motion , and our goal is to determine if the V-T formalism can produce a physically sensible account of this motion. We employ molecular dynamics (MD) data for a system representing liquid Na, and find the motion evolves in three successive time intervals: On the first "vibrational" interval, the vibrational motion alone gives a highly accurate account of the MD data; on the second "crossover" interval, the vibrational MSD saturates to a constant while the transit motion builds up from zero; on the third "random walk" interval, the transit motion produces a purely diffusive random walk of the vibrational equilibrium positions. This motional evolution agrees with, and adds refinement to, the MSD atomic motion as described by current liquid dynamics theories.

description: Motivated by the analysis of high-dimensional neuroimaging signals located over the cortical surface, we introduce a novel Principal Component Analysis technique that can handle functional data located over a two-dimensional manifold. For this purpose a regularization approach is adopted, introducing a smoothing penalty coherent with the geodesic distance over the manifold. The model introduced can be applied to any manifold topology, can naturally handle missing data and functional samples evaluated in different grids of points. We approach the discretization task by means of finite element analysis and propose an efficient iterative algorithm for its resolution. We compare the performances of the proposed algorithm with other approaches classically adopted in literature. We finally apply the proposed method to resting state functional magnetic resonance imaging data from the Human Connectome Project, where the method shows substantial differential variations between brain regions that were not apparent with other approaches.

description: We perform a detailed analysis of how the interplay between the residual binding potential and a strong laser field influences above-threshold ionization (ATI), employing a semi-analytical, Coulomb-corrected strong-field approximation (SFA) in which the Coulomb potential is incorporated in the electron propagation in the continuum. We find that the Coulomb interaction lifts the degeneracy of some SFA trajectories, and we identify a set of orbits which, for high enough photoelectron energies, may be associated with rescattering. Furthermore, by performing a direct comparison with the standard SFA, we show that several features in the ATI spectra can be traced back to the influence of the Coulomb potential on different electron trajectories. These features include a decrease in the contrast, a shift towards lower energies in the interference substructure, and an overall increase in the photoelectron yield. All features encountered exhibit a very good agreement with the \emph{ab initio} solution of the time-dependent Schrödinger equation.

description: The two-dimensional minimal supersymmetric sigma models with homogeneous target spaces $G/H$ and chiral fermions of the same chirality are revisited. We demonstrate that the Moore-Nelson consistency condition revealing a global anomaly in CP(N-1) (with N>2 and ${\mathcal N}=(0,2)$ supersymmetry) due to a nontrivial first Pontryagin class is in one-to-one correspondence with the local anomalies of isometries in these models. These latter anomalies are generated by fermion loop diagrams which we explicitly calculate. In the case of O}(N) sigma models the first Pontryagin class vanishes, so there is no global obstruction for the minimal ${\mathcal N}=(0,1)$ supersymmetrization of these models. We show that at the local level isometries in these models are anomaly free. Thus, there are no obstructions to quantizing the minimal ${\mathcal N}=(0,1)$ models with the $S^{N-1}= SO(N)/SO(N-1)$ target space. This also includes CP(1) (equivalent to $S^{2}$) which is an exceptional case from the CP(N-1) series. We also discuss a relation between the geometric and gauged formulations of the CP}(N-1) models.

Ovarian Cancer Screening and CA-125: A Systematic Literature Review
Creators: name: Roede, Elizabeth C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: This paper investigates the potential role CA-125 has in screening for ovarian cancer. Specifically, it examines the specificity of CA-125 as a screening tool for ovarian cancer in the general population, without specifically looking at women with other risk factors. Since there are no adequate means of screening short of laparotomy, as discussed above, there is no comparison to other screening methods. The outcome measured is simply detection of ovarian cancer. No other interventions will be discussed.

Higher-Order QCD Predictions for Dark Matter Production in Mono-$Z$ Searches at the LHC
Creators: name: Neubert, Matthias
name: Wang, Jian

Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present theoretical predictions for mono-$Z$ production in the search for dark matter in Run-II at the LHC, including next-to-leading order QCD corrections and parton-shower effects. We consider generic simplified models with vector and scalar $s$-channel mediators. The calculation is performed by implementing the simplified models in the FeynRules/MadGraph5_aMC@NLO framework, which allows us to include higher-order QCD corrections and parton-shower effects in an automated way. We find that these corrections are sizeable and help to reduce the theoretical uncertainties. We also investigate the discovery potential in several benchmark scenarios in the 13 TeV run at the LHC.

Propagation of a probe pulse inside a Bose-Einstein condensate under conditions of electromagnetically induced transparency
Creators: name: Barberis-Blostein, Pablo

Subjects: subject: Quantum Physics (quant-ph)

description: We obtain a partial differential equation for a pulse travelling inside a Bose-Einstein condensate under conditions of electromagnetically induced transparency. The equation is valid for a weak probe pulse. We solve the equation for the case of a three-level BEC in $Λ$ configuration with one of its ground state spatial profiles initially constant. The solution characterizes, in detail, the effect that the evolution of the condensate wave function has on pulse propagation, including the process of stopping and releasing it.
North Carolina Health Care Safety Net: Overcoming Barriers to Serving the Uninsured: Are Confidentiality Laws a Barrier to Forming Safety Net Collaborations to Provide Medical Care to the Uninsured?

description: In the United States, the health care safety net plays an important role in providing health care for uninsured individuals. Patient confidentiality is subject to both state and federal law and compliance with these laws is important to insure that safety net providers remain open and available to care for patients. The North Carolina Institute of Medicine suggests that in order to be efficient and provide quality care to patients, safety net providers must find ways to share information with others and collaborate on developing an integrated system of care. Some North Carolina communities have managed to overcome barriers and develop collaborative networks that successfully serve the uninsured. The project described here was developed to understand how these successful collaborative networks have overcome barriers to collaboration with special attention to how they address the issues of sharing patient information and confidentiality. It is a secondary part of a larger project conducted by the North Carolina Institute of Medicine (NC 10M) Safety Net Advisory Council (SNAG). Each of the four community collaboration projects approached patient confidentiality in slightly different ways, though some common themes emerged. The use of clinic-specific medical release of records forms and the use of legal assistance were the most common responses to address patient information sharing. Our findings seem to suggest that modalities for addressing confidentiality will be the same regardless of the level of knowledge regarding state confidentiality laws The case studies presented here provide a list of many other barriers to collaboration between safety net providers beyond those of patient confidentiality. Resource limitations, physician recruitment and medications were the only barriers that surfaced from multiple respondents and from multiple collaboration sites. Other obstacles appear to be unique to the individual collaborations. Our findings suggest that communities who are attempting to develop any type of collaboration need to consider carefully the available resources, physician I provider recruitment, and possible medication provisions in addition to questions surrounding the sharing of patient information. Future research should move beyond barriers to collaboration and should address current and newly emerging barriers to serving communities so that the safety net collaborations are able to continue to provide care for the uninsured.

Torsion-free Word Hyperbolic Groups are Noncommutatively Slender
Creators: name: Corson, Samuel M.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Group Theory (math.GR)
subject: FOS: Mathematics
subject: 14F35

description: In this note we prove the claim given in the title. A group G is noncommutatively slender if each map from the fundamental group of the Hawaiian Earring to G factors through projection to a canonical free subgroup. Graham Higman, in his seminal 1952 paper, proved that free groups are noncommutatively slender. Such groups were first defined by K. Eda. Eda has asked which finitely presented groups are noncommutatively slender. This result demonstrates that random finitely presented groups in the few- relator sense of Gromov are noncommutatively slender.

title: Structural variability as a key to the adaptability of housing architecture: tiny house units for medium-term special housing
Creators: name: Μακκα Ελευθερια
Publisher: name: Technical University of Crete
Year: 2023

description: Η εργασία αφορά στο σχεδιασμό μιας τυπικής μονάδας tiny house, με δυνατότητα προσαρμογής σε διαφορετικές λειτουργίες, μέσω μεταβλητών στοιχείων. Οι διαφορετικές λειτουργίες εξυπηρετούν την κατοίκιση ειδικών ομάδων μεσοπρόθεσμου χρονικού ορίζοντα, όπως είναι οι (μεταπτυχιακοί) φοιτητές, ψηφιακοί νομάδες και καθηγητές τριτοβάθμιας εκπαίδευσης.  Η μεταβλητότητα της δομής επιτυγχάνεται τόσο με μακροκλίμακα με την κίνηση ολόκληρων στοιχείων, όσο και στη μικροκλίμακα με την προσαρμοστικότητα επίπλων και εσωτερικού εξοπλισμού. Η κίνηση επιτυγχάνεται με αναδίπλωση, κατάκλιση / περιστροφή και κύλιση στοιχείων, ώστε να προκύψει μια νέα συνθήκη χώρου ή λειτουργίας. Στοιχεία μεταβλητά υπάρχουν και στο κέλυφος προκειμένου να ορίσουν το ενεργειακό πρόσημο της κατοικίας, ενώ η οργάνωση πολλών μονάδων καθ’ ύψος ή κατ΄ έκταση, δημιουργούν δυνατότητες σύνθετων συγκροτημάτων κατοικιών.
description: The project is about the design of a typical tiny house unit, with the ability to adapt to different functions, through variable elements. The different functions serve to house special medium-term time horizon groups such as (graduate) students, digital nomads and higher education professors.
The variability of the structure is achieved both on a macro scale with the movement of entire elements, and on a micro scale with the adaptability of furniture and interior fittings. Movement is achieved by folding, tilting/rotating and scrolling elements to create a new spatial or functional condition.
Variable elements are also present in the shell in order to define the energy signature of the residence, while the combination of several units by height or area create possibilities for composite housing complexes.
