description: In this work we present the effective field theory of primordial statistical anisotropies generated during anisotropic inflation involving a background $U(1)$ gauge field. Besides the usual Goldstone boson associated with the breaking of time diffeomorphism we have two additional Goldstone bosons associated with the breaking of spatial diffeomorphisms. We further identify these two new Goldstone bosons with the expected two transverse degrees of the $U(1)$ gauge field fluctuations. Upon defining the appropriate unitary gauge, we present the most general quadratic action which respects the remnant symmetry in the unitary gauge. The interactions between various Goldstone bosons leads to statistical anisotropy in curvature perturbation power spectrum. Calculating the general results for power spectrum anisotropy, we recover the previously known results in specific models of anisotropic inflation. In addition, we present novel results for statistical anisotropy in models with non-trivial sound speed for inflaton fluctuations. Also we identify the interaction which leads to birefringence-like effects in anisotropic power spectrum in which the speed of gauge field fluctuations depends on the direction of the mode propagation and the two polarization of gauge field fluctuations contribute differently in statistical anisotropy. As another interesting application, our EFT approach naturally captures interactions generating parity violating statistical anisotropies.

description: Modulated crystals and quasicrystals can simultaneously be described as modulated quasicrystals, a class of point sets introduced by de Bruijn in 1987. With appropriate modulation functions, modulated quasicrystals themselves constitute a substantial subclass of strongly almost periodic point measures. We re-analyse these structures using methods from modern mathematical diffraction theory, thereby providing a coherent view over that class. Similarly to de Bruijn's analysis, we find stability with respect to almost periodic modulations.

description: A mercury (II) sensor has been proposed based on Fluorescence Resonance Energy Transfer (FRET) between N,N'-dioctadecyl thiacyanine perchlorate (NK) and Octadecyl rhodamine B chloride (RhB). Out of these two molecules NK is sensitive to Hg2+ ions due to presence of sulfur atom in it. Accordingly, presence of Hg2+ ions affects the NK fluorescence as well as FRET from NK to RhB. Our results showed that NK fluorescence intensity and FRET efficiency linearly decreases with increase in Hg2+ ion concentration. With proper optimization present system under investigations can be used to sense Hg2+ ions in aqueous solution with detection limit of 9.13 ppb. Advantage of this present system is that it is very simple compared to the other FRET based system and also it works under aqueous environment. This method has also been tested using real lake water and satisfactory results were obtained.

Working together as one: achieving social coordination through positive emotions and self-regulatory resources

description: Social coordination (SC) is a phenomenon that plays out in a host of everyday instances (e.g., flight crew, sports teams), characterized by multiple actors working toward one goal. This study examines the role of emotions and self-regulatory resources (SRR) in facilitating SC among dyads. Ninety-seven pairs of same-sex strangers were recruited for the study and randomly assigned to a SRR manipulation and a partner emotional connectivity task. Following the experimental manipulations, pairs played a laboratory-based SC card game, and then returned one week later to play a second round of the game. Results do not confirm the prediction that positive emotions facilitate SC, and mixed results appear for the interaction of emotions and SRR in facilitating SC. Notably, time emerges as a significant predictor of all SC measures, although no hypotheses were formulated for this effect. Strengths and limitations, and avenues for future research are discussed.

description: The fragmentation of a colored parton directly into a pair of colorless hadrons is a non-perturbative mechanism that offers important insights into the nucleon structure. Di-hadron fragmentation functions can be extracted from semi-inclusive electron-positron annihilation data. They also appear in observables describing the semi-inclusive production of two hadrons in deep-inelastic scattering of leptons off nucleons or in hadron-hadron collisions. When a target nucleon is transversely polarized, a specific chiral-odd di-hadron fragmentation function can be used as the analyzer of the net density of transversely polarized quarks in a transversely polarized nucleon, the so-called transversity distribution. The latter can be extracted through suitable single-spin asymmetries in the framework of collinear factorization, thus in a much simpler framework with respect to the traditional one in single-hadron fragmentation. At subleading twist, the same chiral-odd di-hadron fragmentation function provides the cleanest access to the poorly known twist-3 parton distribution $e(x)$, which is intimately related to the mechanism of dynamical chiral symmetry breaking in QCD. When sensitive to details of transverse momentum dynamics of partons, the di-hadron fragmentation functions for a longitudinally polarized quark can be connected to the longitudinal jet handedness to explore possible effects due to $CP-$violation of the QCD vacuum. In this review, we outline the formalism of di-hadron fragmentation functions, we discuss different observables where they appear and we present measurements and future worldwide plans.

description: This paper presents Knowledge-Based Reinforcement Learning (KB-RL) as a method that combines a knowledge-based approach and a reinforcement learning (RL) technique into one method for intelligent problem solving. The proposed approach focuses on multi-expert knowledge acquisition, with the reinforcement learning being applied as a conflict resolution strategy aimed at integrating the knowledge of multiple exerts into one knowledge base.
 The article describes the KB-RL approach in detail and applies the reported method to one of the most challenging problems of current Artificial Intelligence (AI) research, namely playing a strategy game. The results show that the KB-RL system is able to play and complete the full FreeCiv game, and to win against the computer players in various game settings. Moreover, with more games played, the system improves the gameplay by shortening the number of rounds that it takes to win the game.
 Overall, the reported experiment supports the idea that, based on human knowledge and empowered by reinforcement learning, the KB-RL system can deliver a strong solution to the complex, multi-strategic problems, and, mainly, to improve the solution with increased experience.

description: Mobile cloud computing (MCC) has increasingly been adopted in healthcare industry by healthcare professionals (HCPs) which has resulted in the growth of medical software applications for these platforms. There are different applications which help HCPs with many important tasks. Mobile cloud computing has helped HCPs in better decision making and improved patient care. MCC enables users to acquire the benefit of cloud computing services to meet the healthcare demands. However, the restrictions posed by network bandwidth and mobile device capacity has brought challenges with respect to energy consumption and latency delays. In this paper we propose dynamic energy consumption mobile cloud computing model (DEMCCM) which addresses the energy consumption issue by healthcare mobile devices using dynamic cloudlets.

The structure and hydraulics of natural woody debris jams

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: While the importance of woody debris in rivers has been well-studied within the past few decades, the dynamics of the woody debris jam is often overlooked. This study focuses on the woody debris jam treating it as a complex and porous accumulation of heterogeneous material. Accounting for the momentum extracted as flow passes a debris jam, the drag force on three jams with differing structures, representing varying degrees of porosity, is quantified. Utilizing the drag force equation along with the volume and surface area of the jam, the effect of structure on hydraulics is investigated. A theoretical model for debris jam evolution is hypothesized based on these results and a review of the literature. The results from this study show that 1) natural debris jams are porous structures and 2) piece-size distributions may dictate the evolution of a debris jam and therefore its rate of change in hydraulics.

description: Objectives: To quantify the number and type of complications that occur with a monolithic zirconia implant supported fixed prosthesis (MZISFP) and to examine change in oral health quality of life over the course of six months. Methods: Fifteen edentulous patients were enrolled. Each patient was provided conventional dentures, four mandibular implants, and a mandibular MZISFP. Complication data were recorded over 6 months. The 49-item Oral Health Impact Profile was administered on three occasions: at enrollment, at implant surgery, and at 6-month recall. Results: Seven complications occurred during the MZISFP observation period. Implant survival was 93% and 98% from the patient and implant perspectives respectively. Prosthesis survival was 93%. OHIP-49 severity and extent scores decreased significantly over the course of the study (p<0.001). Conclusions: Complications were infrequent and patient centered outcomes were significantly improved with a MZISFP.

Moreover, we show that the plus construction is redundant in positive characteristic.

description: The data being used were collected as a part of the Love in the Time of COVID study, which launched on March 27th. Baseline data (T1) from over 7000 participants were collected at the beginning of the COVID-19 pandemic and participants were asked to complete follow-up surveys every two weeks. The survey was available in the following languages: English, Spanish, Turkish, Thai, Chinese, Dutch, French, German, Indonesian, Italian, and Portuguese and collection for T1 is now complete. The data for the hypotheses put forth in this pre-registration have not been explored in the Thai, Chinese, Dutch, French, German, Indonesian, Italian, or Portuguese version of the surveys, though the variables of interest have been explored in the English, Spanish, and Turkish versions of the survey for other purposes. The rationale for including the various languages and for this pre-registration is to ensure the effects of interest are being tested among a less WEIRD (i.e., white, educated, industrialized, rich, and democratic; Henrich et al., 2010) sample and to increase the generalizability of the effects.
Inner Structure of Black Holes in Eddington-inspired Born-Infeld gravity: the role of mass inflation

description: We investigate the interior dynamics of accreting black holes in Eddington-inspired Born-Infeld gravity using the homogeneous approximation and taking charge as a surrogate for angular momentum, showing that accretion can have an enormous impact on their inner structure. We find that, unlike in general relativity, there is a minimum accretion rate bellow which the mass inflation instability, which drives the centre-of-mass streaming density to exponentially high values in an extremely short interval of time, does not occur. We further show that, above this threshold, mass inflation takes place inside black holes very much in the same way as in general relativity, but is brought to a halt at a maximum energy density which is, in general, much smaller than the fundamental energy density of the theory. We conjecture that some of these results may be a common feature of modified gravity theories in which significant deviations from general relativity manifest themselves at very high densities.

description: The ongoing pandemic of SARS-CoV-2 calls for rapid and cost-effective methods to accurately identify infected individuals. The vast majority of patient samples is assessed for viral RNA presence by RT-qPCR. Our biomedical research institute, in collaboration between partner hospitals and an accredited clinical diagnostic laboratory, established a diagnostic testing pipeline that has reported on more than 252,000 RT-qPCR results since its commencement at the beginning of April 2020. However, due to ongoing demand and competition for critical resources, alternative testing strategies were sought. In this work, we present a clinically-validated procedure for high-throughput SARS-CoV-2 detection by RT-LAMP in 25 minutes that is robust, reliable, repeatable, sensitive, specific, and inexpensive.

description: For more than 40 years, most astrophysical observations and laboratory studies of two key soft x-ray diagnostic $2p-3d$ transitions, $3C$ and $3D$, in Fe XVII ions found oscillator strength ratios $f(3C)/f(3D)$ disagreeing with theory, but uncertainties had precluded definitive statements on this much studied conundrum. Here, we resonantly excite these lines using synchrotron radiation at PETRA III, and reach, at a millionfold lower photon intensities, a 10 times higher spectral resolution, and 3 times smaller uncertainty than earlier work. Our final result of $f(3C)/f(3D) = 3.09(8)(6)$ supports many of the earlier clean astrophysical and laboratory observations, while departing by five sigmas from our own newest large-scale ab initio calculations, and excluding all proposed explanations, including those invoking nonlinear effects and population transfers.

description: The semi-regular variable star RU Vulpeculae (RU Vul) is being observed visually since 1935. Its pulsation period and amplitude are declining since $\sim1954$. A leading hypothesis to explain the period decrease in asymptotic giant branch (AGB) stars such as RU Vul is an ongoing flash of the He-burning shell, also called a thermal pulse (TP), inside the star. In this paper, we present a CCD photometric light curve of RU Vul, derive its fundamental parameters, and test if the TP hypothesis can describe the observed period decline. We use CCD photometry to determine the present-day pulsation period and amplitude in three photometric bands, and high-resolution optical spectroscopy to derive the fundamental parameters. The period evolution of RU Vul is compared to predictions by evolutionary models of the AGB phase. We find that RU Vul is a metal-poor star with a metallicity $[{\rm M}/{\rm H}]=-1.59\pm0.05$ and an effective surface temperature of $T_{\rm eff}=3634\pm20$ K. The low metallicity of RU Vul and its kinematics indicate that it is an old, low-mass member of the thick disc or the halo population. The present day pulsation period determined from our photometry is $\sim108$ d, the semi-amplitude in the V-band is $0.39\pm0.03$ mag. The observed period decline is found to be well matched by an evolutionary AGB model with stellar parameters comparable to those of RU Vul. We conclude that the TP hypothesis is in good agreement with the observed period evolution of RU Vul.

description: In this experiment, a closed-loop discrete time system for speed control of a permanent magnet DC motor with discrete PI controller is implemented in embedded platform. The design & analysis of the system is based on the mathematical model of the DC motor obtained by system identification technique. After that the closed loop system is distributed through a wireless network created by means of Bluetooth without any change in the discrete controller. The network connects the controller on one side with the sensor, actuator & the plant on the other side. Then the performance of the closed loop system is observed with the wireless network in two configurations : with point-to-point connection between two nodes and a network structure with two intermediate nodes among the controller side node & the plant side node. It has been observed that the performance degrades with only the PI controller a little bit in point to point configuration and the performance severely degrades in intermediate node configuration. To tackle this issue time delay is measured in the WNCS and then a digital smith predictor structure is implemented to obtain better performance. It has been observed that in point to point configuration the time delay remains almost constant and in intermediate node configuration the time delay is varying. Hence the digital smith predictor fails to perform reasonably in intermediate node configuration. An online time delay measurement & estimation procedure has been implemented and proposed in this research. We have implemented an adaptive digital smith predictor using the online time delay measurement and identification. The implemented smith predictor provides good results for both intermediate node and point to point connection. An stability analysis of the DC motor system with variation of delay has been discussed.

description: The author introduced models of linear logic known as ''Interaction Graphs'' which generalise Girard's various geometry of interaction constructions. In this work, we establish how these models essentially rely on a deep connection between zeta functions and the execution of programs, expressed as a cocycle. This is first shown in the simple case of graphs, before begin lifted to dynamical systems. Focussing on probabilistic models, we then explain how the notion of graphings used in Interaction Graphs captures a natural class of sub-Markov processes. We then extend the realisability constructions and the notion of zeta function to provide a realisability model of second-order linear logic over the set of all (discrete-time) sub-Markov processes.

description: Throughout the different phases of a drug development program, randomized trials are used to establish the tolerability, safety, and efficacy of a candidate drug. At each stage one aims to optimize the design of future studies by extrapolation from the available evidence at the time. This includes collected trial data and relevant external data. However, relevant external data are typically available as averages only, for example from trials on alternative treatments reported in the literature. Here we report on such an example from a drug development for wet age-related macular degeneration. This disease is the leading cause of severe vision loss in the elderly. While current treatment options are efficacious, they are also a substantial burden for the patient. Hence, new treatments are under development which need to be compared against existing treatments. The general statistical problem this leads to is meta-analysis, which addresses the question of how we can combine datasets collected under different conditions. Bayesian methods have long been used to achieve partial pooling. Here we consider the challenge when the model of interest is complex (hierarchical and nonlinear) and one dataset is given as raw data while the second dataset is given as averages only. In such a situation, common meta-analytic methods can only be applied when the model is sufficiently simple for analytic approaches. When the model is too complex, for example nonlinear, an analytic approach is not possible. We provide a Bayesian solution by using simulation to approximately reconstruct the likelihood of the external summary and allowing the parameters in the model to vary under the different conditions. We first evaluate our approach using fake-data simulations and then report results for the drug development program that motivated this research.

description: We resonantly excite the $K$ series of O$^{5+}$ and O$^{6+}$ up to principal quantum number $n=11$ with monochromatic x rays, producing $K$-shell holes, and observe their relaxation by soft-x-ray emission. Some photoabsorption resonances of O$^{5+}$ reveal strong two-electron--one-photon (TEOP) transitions. We find that for the $[(1s\,2s)_1\,5p_{3/2}]_{3/2;1/2}$ states, TEOP relaxation is by far stronger than the radiative decay and competes with the usually much faster Auger decay path. This enhanced TEOP decay arises from a strong correlation with the near-degenerate upper states $[(1s\,2p_{3/2})_1\,4s]_{3/2;1/2}$ of a Li-like satellite blend of the He-like $Kα$ transition. Even in three-electron systems, TEOP transitions can play a dominant role, and the present results should guide further research on the ubiquitous and abundant many-electron ions where electronic energy degeneracies are far more common and configuration mixing is stronger.

description: We consider a transmission problem consisting of a semilinear parabolic equation in a general non-smooth setting with emphasis on rough interfaces which bear a fractal-like geometry and nonlinear dynamic (possibly, nonlocal)\ boundary conditions along the interface. We give a unified framework for existence of strong solutions, existence of finite dimensional attractors and blow-up phenomena for solutions under general conditions on the bulk and interfacial nonlinearities with competing behavior at infinity.

Tragedy

description: Daniele Nuccetelli, actor in Filottete dimenticato (The Forgotten Philoctetes), shares his personal experience of approaching the world of neurodegenerative diseases. By retracing the myth of Philoctetes through the story of an abandoned father, Nuccetelli suggests a new interpretation for the word ‘hero’, and asks that we should question whether Philoctetes is alone in his suffering.
Reactor for boron fusion with picosecond ultrahigh power laser pulses and ultrahigh magnetic field trapping

description: Compared with the deuterium tritium (DT) fusion, the environmentally clean fusion of protons with 11B is extremely difficult. When instead of nanosecond laser pulses for thermal-ablating driven ignition, picosecond pulses are used, a drastic change by nonlinearity results in ultrahigh acceleration of plasma blocks. This radically changes to economic boron fusion by a measured new avalanche ignition.

description: In today's day and time solving real-world complex problems has become fundamentally vital and critical task. Many of these are combinatorial problems, where optimal solutions are sought rather than exact solutions. Traditional optimization methods are found to be effective for small scale problems. However, for real-world large scale problems, traditional methods either do not scale up or fail to obtain optimal solutions or they end-up giving solutions after a long running time. Even earlier artificial intelligence based techniques used to solve these problems could not give acceptable results. However, last two decades have seen many new methods in AI based on the characteristics and behaviors of the living organisms in the nature which are categorized as bio-inspired or nature inspired optimization algorithms. These methods, are also termed meta-heuristic optimization methods, have been proved theoretically and implemented using simulation as well used to create many useful applications. They have been used extensively to solve many industrial and engineering complex problems due to being easy to understand, flexible, simple to adapt to the problem at hand and most importantly their ability to come out of local optima traps. This local optima avoidance property helps in finding global optimal solutions. This paper is aimed at understanding how nature has inspired many optimization algorithms, basic categorization of them, major bio-inspired optimization algorithms invented in recent time with their applications.
Large-Dimensional Dynamic Factor Models: Estimation of Impulse-Response Functions with $I(1)$ Cointegrated Factors

Year: 2016

subject: FOS: Computer and information sciences

description: We study a large-dimensional Dynamic Factor Model where: (i)~the vector of factors $\mathbf F_t$ is $I(1)$ and driven by a number of shocks that is smaller than the dimension of $\mathbf F_t$; and, (ii)~the idiosyncratic components are either $I(1)$ or $I(0)$. Under~(i), the factors $\mathbf F_t$ are cointegrated and can be modeled as a Vector Error Correction Model (VECM). Under (i) and (ii), we provide consistent estimators, as both the cross-sectional size $n$ and the time dimension $T$ go to infinity, for the factors, the loadings, the shocks, the coefficients of the VECM and therefore the Impulse-Response Functions (IRF) of the observed variables to the shocks.~Furthermore: possible deterministic linear trends are fully accounted for, and the case of an unrestricted VAR in the levels $\mathbf F_t$, instead of a VECM, is also studied. The finite-sample properties the proposed estimators are explored by means of a MonteCarlo exercise. Finally, we revisit two distinct and widely studied empirical applications. By correctly modeling the long-run dynamics of the factors, our results partly overturn those obtained by recent literature. Specifically, we find that: (i) oil price shocks have just a temporary effect on US real activity; and, (ii) in response to a positive news shock, the economy first experiences a significant boom, and then a milder recession.
Brand and Reputation Resilience in Times of Crisis: The National Football League, Ray Rice and Social Media
Creators: name: Jones, Tiffany

description: For six seasons, Ray Rice was an integral part of the Baltimore Ravens offensive attack. With an average of 4.3 yards per carry and 67.2 yards per game, Rice helped establish the team as a solid contender in the NFL (Players – Ray Rice, n.d.). Off the field, he spent time hosting camps and rallies, as well as promoting initiatives, such as his, “A Ray of Hope: A Pro-Kindness, Anti-Bullying, Teen Suicide Prevention Outreach.” (Ray Rice Makes Impact, 2012) Unfortunately, for Rice, the Ravens and the NFL, none of that mattered when TMZ released video of Rice dragging his fiancée, Janay Palmer, from an elevator. The 2014-15 NFL season was marred with negative media attention — traditional and social — ending with Rice’s release from the Ravens. This paper explores contributions of traditional and social media to the Rice and NFL’s campaign to protect the league’s brand and reputation during the 2014-15 season.
Integration of Pre-aligned Liquid Metal Electrodes for Neuronal Stimulation within an easy-to-assemble Microfluidic Platform
Creators: name: Hallfors, Nicholas George
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Neural stimulation and recording techniques play a critical role in understanding the nervous system. Electrophysiological experiments on neurons may lead to new clinical treatments for chronic neurodegenerative disease, as well as acute neural injury. A major limiting factor in the study of neurons is the cost and complexity of existing suitable research platforms. In this study, a low cost, easily fabricated research platform was developed for the study of neurons. Using basic photolithographic techniques and readily available materials, a compartmentalized microfluidic chamber with pre-aligned microelectrodes was developed. Neurons were grown in the devices and subjected to electrical stimulation, and fluorescence microscopy data was collected on neural response to stimulation and neural compatibility to the devices.
Antagonism in Daily Life: An Exploratory Ecological Momentary Assessment Study

description: Interpersonal Antagonism is one of the major domains of maladaptive personality. Structural-based investigations of Antagonism have generally been consistent in highlighting the more specific antagonistic traits (e.g., manipulativeness, callousness) that underlie the broader domain. However, less work has attempted to merge structural and functional accounts of Antagonism to assess how specific antagonistic traits manifest in daily life. This exploratory study examined how Antagonism and its specific features relate to outcomes assessed using ecological momentary assessment (EMA) methods. Across four independent EMA samples (N range=297-396; total N = 1,365; observations per outcome=5,419-17,735), we investigated how antagonistic traits related to theoretically relevant, EMA-based outcomes (e.g., affect, empathy, coldness-warmth in interpersonal interactions). Results showed robust findings across samples and operationalizations of Antagonism (e.g., Antagonism’s relation with negative affect), along with more mixed results (e.g., Antagonism’s relation with different measures of empathy). We discuss future research directions for structural and functional accounts of Antagonism.
Temperature response in nonequilibrium stochastic systems

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The linear response to temperature changes is derived for systems with overdamped stochastic dynamics. Holding both in transient and steady state conditions, the results allow to compute nonequilibrium thermal susceptibilities from unperturbed correlation functions. These correlations contain a novel form of entropy flow due to temperature unbalances, next to the standard entropy flow of stochastic energetics and to complementary time-symmetric dynamical aspects. Our derivation hinges on a time rescaling, which is a key procedure for comparing apparently incommensurable path weights. An interesting notion of thermal time emerges from this approach.

The new rise of economic nationalism in transatlantic trade relations
Creators: name: Fölster, Christian Alexander
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This paper seeks to explain the new rise of economic nationalism in transatlantic trade relations. By examining the arguments that were raised in favor for protectionism in America and in Europe, this paper identifies three different concepts of economic nationalism, along with the arguments can be structured and explained. The author argues that economic nationalism can be explained either as an ideological, economical or cultural concept, which can explain why protectionist policies are a common answer in times of economic crisis. This paper contributes to the debate about the conception of economic nationalism and its implications for transatlantic relations.
Multiple instance learning for sequence data with across bag dependencies

description: In Multiple Instance Learning (MIL) problem for sequence data, the instances inside the bags are sequences. In some real world applications such as bioinformatics, comparing a random couple of sequences makes no sense. In fact, each instance may have structural and/or functional relations with instances of other bags. Thus, the classification task should take into account this across bag relation. In this work, we present two novel MIL approaches for sequence data classification named ABClass and ABSim. ABClass extracts motifs from related instances and use them to encode sequences. A discriminative classifier is then applied to compute a partial classification result for each set of related sequences. ABSim uses a similarity measure to discriminate the related instances and to compute a scores matrix. For both approaches, an aggregation method is applied in order to generate the final classification result. We applied both approaches to solve the problem of bacterial Ionizing Radiation Resistance prediction. The experimental results of the presented approaches are satisfactory.
