description: We present the newly developed stochastic model of the galactic cosmic ray (GCR) particles transport in the heliosphere. Mathematically Parker transport equation (PTE) describing non-stationary transport of charged particles in the turbulent medium is the Fokker-Planck type. It is the second order parabolic time-dependent 4-dimensional (3 spatial coordinates and particles energy/rigidity) partial differential equation. It is worth to mention that, if we assume the stationary case it remains as the 3-D parabolic type problem with respect to the particles rigidity R. If we fix the energy it still remains as the 3-D parabolic type problem with respect to time. The proposed method of numerical solution is based on the solution of the system of stochastic differential equations (SDEs) being equivalent to the Parker's transport equation. We present the method of deriving from PTE the equivalent SDEs in the heliocentric spherical coordinate system for the backward approach. The obtained stochastic model of the Forbush decrease of the GCR intensity is in an agreement with the experimental data. The advantages and disadvantages of the forward and the backward solution of the PTE are discussed.

description: The effective action of the recently proposed vector Galileon theory is considered. Using the background field method, we obtain the one-loop correction to the propagator of the Proca field from vector Galileon self-interactions. Contrary to the so-called scalar Galileon interactions, the two-point function of the vector field gets renormalized at the one-loop level, indicating that there is no non-renormalization theorem in the vector Galileon theory. Using dimensional regularization, we remove the divergences and obtain the counterterms of the theory. The finite term is analytically calculated, which modifies the propagator and the mass term and generates some new terms also.

Acute HPA Axis Responses to Social Stress Longitudinally Predict Adolescent Girls’ Depressive Symptoms: The Moderating Role of Subjective Stress Responses
Creators: name: Owens, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Increases in interpersonal stress and depressive symptoms during adolescence have stimulated greater attention to stress response models of adolescent depression, but it remains unclear why only certain adolescents are vulnerable to the depressogenic effects of stress while others are not. The current study examined associations among experiences of interpersonal stress, affective reactivity, and hypothalamic-pituitary-adrenal (HPA) axis reactivity to an in-vivo psychosocial stressor as prospective predictors of depressive symptoms nine months later. Hypotheses were examined with a clinically oversampled group of 109 adolescent girls (aged 12-16) to ensure an examination of the widest possible range of prior life stress. Results indicate that adolescent girls who are most emotionally and physiologically reactive to stress and experience significant social stress are most likely to experience elevated levels of depressive symptoms longitudinally. Findings suggest that it may be critical to examine both physiological and affective stress responses when assessing risk for depression in adolescents.

description: A general characterization for α-unimodal distributions was provided by Alamatsaz (1985) who later introduced a multivariate extension of them (Alamatsaz 1993). Here, by solving the related equations, another generalization for unimodality is presented. As a result of this generalization, a simpler proof of a conjecture, as well as a characterization for generalized arcsin distributions and some generalizations of the author's earlier works, have been obtained. Last, but not the least, it is shown that some elementary methods can be more powerful than some more advanced techniques.

Faster Gaze before Telling Untruthful Narratives
Creators: name: Chengli, Huang
Publisher: name: Open Science Framework
Year: 2022

description: Being one of the simplest and easily observed gaze behaviours, the speed of eye movement, is generally ignored in the research of lying. Can there be a speed related index to gaze behaviour that relates to deception? To explore this question, an eye-tracking study was conducted: in a controlled naturalistic conversational context, the participants were asked to prepare, and subsequently to tell, a truthful or untruthful narrative. The results indicate that gaze velocity is higher when preparing untruthful narratives than truthful ones. Moreover, gaze velocity was significantly lower when preparing a truthful narrative than when telling it, but this was not observed in the case of lying. Therefore, the tell coming from the eyes would be observed before a person lies or tells the truth, and not while the lie or the truth is being told.

description: In this paper, we report the observation and exploitation of the capability of light to self-organize its state-of-polarization, upon propagation in optical fibers, by means of a device called Omnipolarizer. The principle of operation of this system consists in a counter-propagating four-wave mixing interaction between an incident signal and its backward replica generated at the fiber output thanks to a reflective fiber loop. We have exploited this self-induced polarization tracking phenomenon for all-optical data processing and successfully demonstrated the spontaneous repolarization of a 40-Gbit/s On-Off keying optical signal without noticeable impairments. Moreover, the strong local coupling between the two counter-propagating waves has also revealed a fascinating aspect of the Omnipolarizer called polarization-based tunneling effect. This intrinsic property enables us to instantaneously let jump a polarization information onto the reflected signal, long before the expected time-of-flight induced by the round-trip along the fiber span. Finally, we discuss how the concept of self-organization could be generalized to multimode fibers, which paves the way to new important applications in the framework of spatial-mode-multiplexing.

description: This study examines the relationship between religious rituals and the way people perceive moral norms. Based on the theories from anthropology, we expect that rituals charge moral symbols with which rituals are associated with essence. On the psychological level, this should be manifested through the facilitated perception of moral norms as independent on time, place and human subjects. This hypothesis is tested in the experimental design where participants are primed by religious rituals through instruction to write about their collective religious rituals. Norm objectivity is measure using modified scales established in literature.

description: Few-layer black phosphorus was recently rediscovered as a narrow-bandgap atomically thin semiconductor and has already attracted unprecedented attention due to its interesting properties. One feature of this material that sets it apart from other atomically thin crystals is its structural in-plane anisotropy which manifests in strongly anisotropic transport characteristics. However, traditional angle-resolved conductance measurements present a challenge for nanoscale systems such as black phosphorus, calling for new approaches in precision studies of transport anisotropy. Here we show that the nonlocal response, being exponentially sensitive to the anisotropy value, provides a powerful tool for determining the anisotropy. This is established by combining measurements of the orientation-dependent nonlocal resistance response with the analysis based on the anamorphosis relations. We demonstrate that the nonlocal response can differ by orders of magnitude for different crystallographic directions even when the anisotropy is at most order-one, allowing us to extract accurate anisotropy values.
Galaxy structure from multiple tracers: I. A census of M87's globular cluster populations

description: We present a new photometric catalogue of the rich globular cluster (GC) system around M87, the brightest cluster galaxy in Virgo. Using archival Next Generation Virgo cluster Survey (NGVS) images in the ugriz bands, observed with CFHT/MegaPrime, we perform a careful subtraction of the galaxy's halo light in order to detect objects at small galactocentric radii as well as in the wider field, and find 17620 GC candidates over a radius range from 1.3 kpc to 445 kpc with g < 24 magnitudes. By inferring their colour, radial and magnitude distributions in a Bayesian way, we find that they are well described as a mixture of two GC populations and two distinct contaminant populations, but confirm earlier findings of radius-dependent colour gradients in both GC populations. This is consistent with a picture in which the more enriched GCs reside deeper in the galaxy's potential well, indicating a role for dissipative collapse in the formation of both the red and the blue GCs.

Attospiral generation upon interaction of circularly polarized intense laser pulses with cone-like targets

description: Generation of high intensity attopulses is investigated in cylindrical geometry by using 3D particle-in-cell plasma simulation code. Due to the rotation symmetric target, a circularly polarized laser pulse is considered propagating on the axis of a hollow cone-like target. The large incidence angle and constant ponderomotive pressure leads to nano-bunching of relativistic electrons responsible for the laser-driven synchrotron emission. A numerical method is developed to find the source and direction of the coherent radiation that is responsible for the existence of attopulses. The intensity modulation in the harmonic spectrum is well described by the model of coherent synchrotron emission extended to the regime of higher order γ-spikes. The spatial distribution of the higher harmonics resembles a spiral shape which gets focused into a small volume behind the target.

description: We investigate thermodynamic equilibrium of a self-gravitating perfect fluid in a spherically symmetric system containing a black hole of mass M by means of the Tolman-Oppenheimer-Volkoff (TOV) equation. At r >> 2M its solutions describe a black-body radiation atmosphere with the Hawking temperature T_BH~1/(8 πM) that is increasingly blueshifted as r approaches 2M. However, there is no horizon at the Schwarzschild radius. Instead, the fluid becomes increasingly hot and dense there, piling up into a "firewall" with the peak temperatures and densities reaching Planck values somewhat below r = 2M. This firewall surrounds a negative point mass residing at r=0, the only singularity of the solution. The entropy of the firewall is comparable to the Bekenstein-Hawking entropy.

Adaptive-Robust Control of a Class of Nonlinear Systems with Unknown Input Delay

Subjects: subject: Systems and Control (eess.SY)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: In this paper, the tracking control problem of a class of uncertain Euler-Lagrange systems subjected to unknown input delay and bounded disturbances is addressed. To this front, a novel delay dependent control law, referred as Adaptive Robust Outer Loop Control (AROLC) is proposed. Compared to the conventional predictor based approaches, the proposed controller is capable of negotiating any input delay, within a stipulated range, without knowing the delay or its variation. The maximum allowable input delay is computed through Razumikhin-type stability analysis. AROLC also provides robustness against the disturbances due to input delay, parametric variations and unmodelled dynamics through switching control law. The novel adaptive law allows the switching gain to modify itself online in accordance with the tracking error without any prerequisite of the uncertainties. The uncertain system, employing AROLC, is shown to be Uniformly Ultimately Bounded (UUB). As a proof of concept, experimentation is carried out on a nonholonomic wheeled mobile robot with various time varying as well as fixed input delay, and better tracking accuracy of the proposed controller is noted compared to predictor based methodology.

description: Dysfunction along the gut-brain axis (GBA) is increasingly implicated in the pathogenesis of autism spectrum disorders (ASD). In addition to its neurodevelopmental deficits, ASD is also characterized by a range of gastrointestinal symptoms, which increase in proportion to the severity of ASD. Moreover, many studies have found that those with ASD have an altered intestinal microbiome composition. Given these associations, we propose to examine the use and effect of probiotics, prebiotics, and antibiotics on the gut-brain-microbiome axis as they pertain to the behavioral manifestations of ASD. Current data is inconsistent across the field, and the quality of individual studies is highly variable, and existing reviews only examine prebiotics, probiotics, or antibiotics separately. We hypothesize that by systematically examining the interplay between these three microbiome-based interventions, a broader trend may be elucidated regarding the efficacy of gut-microbiome based intervention in ASD that will guide future investigations.

description: We report room-temperature Coulomb blockade in a single layer graphene three-terminal single-electron transistor (SET) fabricated using feedback-controlled electroburning. The small separation between the side gate electrode and the graphene quantum dot results in a gate coupling up to 3 times larger compared to the value found for the back gate electrode. This allows for an effective tuning between the conductive and Coulomb blocked state using a small side gate voltage of about 1V. The technique can potentially be used in the future to fabricate all-graphene based room temperature single-electron transistors or three terminal single molecule transistors with enhanced gate coupling.

description: This paper analyses the effect of preferential sampling in Geostatistics when the choice of new sampling locations is the main interest of the researcher. A Bayesian criterion based on maximizing utility functions is used. Simulated studies are presented and highlight the strong influence of preferential sampling in the decisions. The computational complexity is faced by treating the new local sampling locations as a model parameter and the optimal choice is then made by analysing its posterior distribution. Finally, an application is presented using rainfall data collected during spring in Rio de Janeiro. The results showed that the optimal design is substantially changed under preferential sampling effects. Furthermore, it was possible to identify other interesting aspects related to preferential sampling effects in estimation and prediction in Geostatistics.

description: The past decade has seen atomic Bose-Einstein condensates emerge as a promising prototype system to explore the quantum mechanical form of turbulence, buoyed by a powerful experimental toolbox to control and manipulate the fluid, and the amenity to describe the system from first-principles. This article presents an overview of quantum turbulence in atomic condensates, from its history and fundamental motivations, its characteristics and key results to date, and finally to some promising future directions.

Quantum quench in 2D using the variational Baeriswyl wavefunction

description: By combining the Baeriswyl wavefunction with equilibrium and time-dependent variational principles, we develop a non-equilibrium formalism to study quantum quenches for two dimensional spinless fermions with nearest-neighbour hopping and repulsion. The variational ground state energy and the short time dynamics agree convincingly with the results of numerically exact simulations. We find that depending on the initial and final interaction strength, the quenched system either exhibits undamped oscillations or relaxes to a time independent steady state. The time averaged expectation value of the CDW order parameter rises sharply when crossing from the steady state regime to the oscillating regime, indicating that the system, being non-integrable, shows signs of thermalization with an effective temperature above or below the equilibrium critical temperature, respectively.

description: We present scattering cross sections $σ_\text{scatt}$ of ultracold neutrons (UCN) in liquid deuterium at T = 20.6 K, as recently measured by means of a transmission experiment. The indispensable thorough raw data treatment procedure is explained. A calculation model for coherent and incoherent scattering in liquid deuterium in the hydrodynamic limit based on appropriate physical concepts is provided and shown to fit the data well. The applicability of the incoherent approximation for UCN scattering in liquid deuterium was tested and found to deliver acceptable results.

The development of a semi-quantitative decision support system for the estimation of microbial loading in the Neuse watershed using geographic information systems
Creators: name: Cressman, Anna Marlene
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Decision support systems (DSS) are often employed in complex environmental problems to provide the user with an integrated solution approach and can range from purely qualitative to quantitative modeling to fully automated. This paper presents a semiquantitative DSS approach for the problem of microbial loading in surface waters due to stormwater runoff. Six important stormwater variables are identified within the Neuse River Basin, N.C. Linear regression is used to assess the correlation of each variable with measured fecal coliform levels in surface waters. The resultant DSS provides a relative ranking of each variable based on its predictive value and a scaling based on its dynamic range. The DSS presented provides a less complex, less resource intensive approach to the problem posed than other available stormwater modeling programs, but also provides a more reliable estimate of risk than a purely qualitative DSS.

Magnetic grain trapping and the hot excesses around early-type stars

description: A significant fraction of main sequence stars observed interferometrically in the near infrared have slightly extended components that have been attributed to very hot dust. To match the spectrum appears to require the presence of large numbers of very small (< 200 nm in radius) dust grains. However, particularly for the hotter stars, it has been unclear how such grains can be retained close to the star against radiation pressure force. We find that the expected weak stellar magnetic fields are sufficient to trap nm-sized dust grains in epicyclic orbits for a few weeks or longer, sufficient to account for the hot excess emission. Our models provide a natural explanation for the requirement that the hot excess dust grains be smaller than 200 nm. They also suggest that magnetic trapping is more effective for rapidly rotating stars, consistent with the average vsini measurements of stars with hot excesses being larger (at about 2 sigma) than those for stars without such excesses.
