description: Overview: The subjective perception of time holds a foundational significance within the realm of human psychology and our conceptualizations of reality. It forms an intrinsic component of the cognitive framework through which we elucidate the chronological progression of events within our lives. While some studies have examined the effects of exercise on time perception during the exercise period, there are no studies investigating the effects of fatiguing exercise on time perception after the exercise intervention. Thus, this study aimed to investigate the effects of physical and mental fatigue on time estimates over 30-seconds (5-, 10-, 20-, and 30-seconds) immediately after the exercise intervention and 6-minutes after the post-test. Participants: Seventeen healthy and recreationally active volunteers (14 males, 3 females) were subjected to three conditions: physical, mental fatigue, and control. Methods: All participants completed a familiarization and three experimental conditions (control, physical fatigue (cycling at 65% peak power output for 30 minutes), and mental fatigue (Stroop task for 1100 trials for 30 minutes) on separate days. Heart rate and body temperature were recorded at the pre-test, the start, 10-, 20-, 30- minutes of the intervention, post-test, and follow-up. Rating of perceived exertion (RPE) was also recorded during the intervention four times. Time perception was measured prospectively (at 5-, 10-, 20-, and 30-seconds) at the pre-test, post-test, and 6-minute follow-up. Results: Physical fatigue significantly (p=0.001) underestimated time compared to mental fatigue and control conditions at the post-test and follow-up, with no significant differences between mental fatigue and control conditions. Heart rate, body temperature, and RPE were significantly higher in the physical fatigue compared to the mental fatigue and control conditions during the intervention and also at the post-test. Conclusion: This study demonstrated that cycling fatigue led to time underestimation compared to mental fatigue and control conditions. It is crucial to consider that physical fatigue has the potential to lengthen an individual's perception of time when estimating durations in sports or work environments.

Anisotropic charge screening and supercell size convergence of defect formation energies

description: One of the main sources of error associated with the calculation of defect formation energies using plane-wave Density Functional Theory (DFT) is finite size error resulting from the use of relatively small simulation cells and periodic boundary conditions. Most widely-used methods for correcting this error, such as that of Makov and Payne, assume that the dielectric response of the material is isotropic and can be described using a scalar dielectric constant $ε$. However, this is strictly only valid for cubic crystals, and cannot work in highly-anisotropic cases. Here we introduce a variation of the technique of extrapolation based on the Madelung potential, that allows the calculation of well converged dilute limit defect formation energies in non-cubic systems with highly anisotropic dielectric properties. As an example of the implementation of this technique we study a selection of defects in the ceramic oxide Li$_2$TiO$_3$ which is currently being considered as a lithium battery material and a breeder material for fusion reactors.

description: We have imaged 24 spectral lines in the Central Molecular Zone (CMZ) around the Galactic Centre, in the range 42 to 50 GHz. The lines include emission from the CS, CH3OH, HC3N, SiO, HNCO, HOCO+, NH2CHO, OCS, HCS+, CCS, C34S, 13CS, 29SiO, H13CCCN, HCC13CN and HC5}N molecules, and three hydrogen recombination lines. The area covered is Galactic longitude -0.7 to 1.8 deg. and latitude -0.3 to 0.2 deg., including the bright cores around Sgr A, SgrB2, SgrC and G1.6-0.025. This work used the 22-m Mopra radio telescope in Australia, obtaining ~ 1.8 km/s spectral and ~ 65 arcsec spatial resolution. We present peak images from this study and conduct a principal component analysis on the integrated emission from the brightest 10 lines, to study similarities and differences in the line distribution. We examine the integrated line intensities and line ratios in selected apertures around the bright cores, as well as for the complete mapped region of the CMZ. We compare these 7-mm lines to the corresponding lines in the 3-mm band, for five molecules, to study the excitation. There is a variation in 3-mm to 7-mm line ratio across the CMZ, with relatively higher ratio in the centre around Sgr B2 and Sgr A. We find that the lines are sub-thermally excited, and from modelling with RADEX find that non-LTE conditions apply, with densities of order 10^4 cm^{-3}.

description: Recent advancements in whole slide digital scanning and increased focus in personalized precision medicine has paved way for research in digital pathology, especially in the application of machine learning (ML) to infer pathological diagnoses. While interest in ML applications in digital pathology is strong, conducting meaningful research in this field demands significant allocation of computational resources. Therefore, there is an urgent need for a scalable digital pathology platform that not only provides tools for Whole Slide Image (WSI) processing but can also efficiently allocate computing resources and upload results to a centralized database. To meet this need, we present SPE3D (Scalable digital Pathology Experimentation in 3D), a state-of-the art, robust, cloud-based digital pathology platform that allows end-to-end processing of pathology images to both train models and run inference at scale. The platform is designed to ingest 2D and 3D tissue samples, process them to create any necessary datasets, and then use the datasets to train and evaluate a collection of models from classical ML models to deep neural networks. The platform runs entirely on a cloud-based infrastructure comprised of CPU and GPU nodes, high-performance machine storage, as well as distributed object storage. The platform can scale the number of nodes required to perform each of the operations based on workload by making extensive use of containerization and workflow-based approaches. Furthermore, the platform supports modern machine learning toolkits, allowing reusability of individual components as well as rapid deployment, prototyping and validation of novel algorithms. Finally, we benchmarked the platform on several 2D and 3D digital pathology datasets to demonstrate its computational capacity as well as the quality of its output datasets.

description: Using the critical Casimir force, we study the attractive-strength dependence of diffusion-limited colloidal aggregation in microgravity. By means of near field scattering we measure both the static and dynamic structure factor of the aggregates as the aggregation process evolves. The simultaneous measurement of both the static and dynamic structure factor under ideal microgravity conditions allows us to uniquely determine the ratio of the hydrodynamic and gyration radius as a function of the fractal dimension of the aggregate, enabling us to elucidate the internal structure of the aggregates as a function of the interaction potential. We find that the mass is evenly distributed in all objects with fractal dimension ranging from 2.55 for a shallow to 1.75 for the deepest potential.

description: A PDE-based model combining surface electromigration and wetting is developed for the analysis of morphological stability of ultrathin solid films. Adatom mobility is assumed anisotropic, and two directions of the electric field (parallel and perpendicular to the surface) are discussed and contrasted. Linear stability analyses of small-slope evolution equations are performed, followed by computations of fully nonlinear parametric evolution equations that permit surface overhangs. The results reveal parameter domains of instability for wetting and non-wetting films and variable electric field strength, nonlinear steady-state solutions in certain cases, and interesting coarsening behavior for strongly wetting films.

description: The generation of ac modulated quantized current waveforms using a semiconductor non-adiabatic single electron pump is demonstrated. In standard operation the single electron pump generates a quantized output current of I = ef where e is the charge of the electron and f is the pumping frequency. Suitable frequency modulation of f allows the generation of ac modulated output currents with different characteristics. By sinusoidal and saw tooth like modulation of f accordingly modulated quantized current waveforms with kHz modulation frequencies and peak currents up to 100 pA are obtained. Such ac quantized current sources could find applications ranging from precision ac metrology to on-chip signal generation.

Events are selected with W [superscript ±] → ℓ [superscript ±] ν and J/ψ → µ⁺µ⁻. The ratio of the prompt J/ψ + W [superscript ±] cross-section to the inclusive W [superscript ±] cross-section is presented for J/ψ transverse momenta in the range 8 − 200 GeV and rapidity |y [subscript J/ψ]| < 2.1, and is presented as a differential measurement as a function of J/ψ transverse momenta and rapidity. Comparisons are made with theoretical predictions for single-parton and double-parton production events.

description: Unusual features in the bias dependence of spin transport are observed in a Co/Au/NiFe spin valve fabricated on a highly textured Cu(100)/Si(100) Schottky interface, exploiting the local probing capabilities of a Ballistic electron magnetic microscope (BEMM). This arises due to local differences in the strain and the presence of misfit dislocations at the Schottky interface that enhances spin flip scattering and broadens the energy and angular distribution of the transmitted electrons. Cumulatively, these enable the transmitted hot electrons to probe the different conduction band minima in Si, giving rise to such bias dependent features in the magnetocurrent. This study reveals new insights into the spin dependence of transmission in an indirect band gap semiconductor as Si and highlights the unique capabilities of BEMM in probing local differences in spin transport across such textured interfaces.

description: Membrane budding and wrapping of particles, such as viruses and nano-particles, play a key role in intracellular transport and have been studied for a variety of biological and soft matter systems. We study nano-particle wrapping by numerical minimization of bending, surface tension, and adhesion energies. We calculate deformation and adhesion energies as a function of membrane elastic parameters and adhesion strength to obtain wrapping diagrams. We predict unwrapped, partially-wrapped, and completely-wrapped states for prolate and oblate ellipsoids for various aspect ratios and particle sizes. In contrast to spherical particles, where partially-wrapped states exist only for finite surface tensions, partially-wrapped states for ellipsoids occur already for tensionless membranes. In addition, the partially-wrapped states are long-lived, because of an increased energy cost for wrapping of the highly-curved tips. Our results suggest a lower uptake rate of ellipsoidal particles by cells and thereby a higher virulence of tubular viruses compared with icosahedral viruses, as well as co-operative budding of ellipsoidal particles on membranes.

description: Superradiant scattering processes are studied in general relativistic systems which, unlike rotating and/or charged black holes, do not exhibit an event horizon. Inspired by Zel'dovich's seminal works on the amplification of waves by a rotating cylinder, we analyse, in the context of General Relativity, the possibility of superradiance for electromagnetic waves reflecting off a rotating star and for charged scalar perturbations impinging on a charged sphere. The role of energy dissipation in these systems is analysed and compared with the role of the event horizon in black hole superradiance.

description: We investigate the nature of gas accretion onto haloes and galaxies at z=2 using cosmological hydrodynamic simulations run with the moving mesh code AREPO. Implementing a Monte Carlo tracer particle scheme to determine the origin and thermodynamic history of accreting gas, we make quantitative comparisons to an otherwise identical simulation run with the smoothed particle hydrodynamics (SPH) code GADGET-3. Contrasting these two numerical approaches, we find significant physical differences in the thermodynamic history of accreted gas in haloes above 10^10.5 solar masses. In agreement with previous work, GADGET simulations show a cold fraction near unity for galaxies forming in massive haloes, implying that only a small percentage of accreted gas heats to an appreciable fraction of the virial temperature during accretion. The same galaxies in AREPO show a much lower cold fraction, <20% in haloes above 10^11 solar masses. This results from a hot gas accretion rate which, at this same halo mass, is an order of magnitude larger than with GADGET, while the cold accretion rate is also lower. These discrepancies increase for more massive systems, and we explain both as due to numerical inaccuracies in the standard formulation of SPH. We also observe that the relatively sharp transition from cold to hot mode dominated accretion, at a halo mass of ~10^11, is a consequence of comparing past gas temperatures to a constant threshold value independent of virial temperature. Examining the spatial distribution of accreting gas, we find that gas filaments in GADGET tend to remain collimated and flow coherently to small radii, or artificially fragment and form a large number of purely numerical "blobs". Similar gas streams in AREPO show increased heating and disruption at 0.25-0.5 virial radii and contribute to the hot gas accretion rate in a manner distinct from classical cooling flows.

description: Energetic nonthermal particles (cosmic rays, CRs) are accelerated in supernova remnants, relativistic jets and other astrophysical objects. The CR energy density is typically comparable with that of the thermal components and magnetic fields. In this review we discuss mechanisms of magnetic field amplification due to instabilities induced by CRs. We derive CR kinetic and magnetohydrodynamic equations that govern cosmic plasma systems comprising the thermal background plasma, comic rays and fluctuating magnetic fields to study CR-driven instabilities. Both resonant and non-resonant instabilities are reviewed, including the Bell short-wavelength instability, and the firehose instability. Special attention is paid to the longwavelength instabilities driven by the CR current and pressure gradient. The helicity production by the CR current-driven instabilities is discussed in connection with the dynamo mechanisms of cosmic magnetic field amplification.

description: In previous works we introduced a nonlinear force-free method that self-consistently calculates the instantaneous budgets of free magnetic energy and relative magnetic helicity in solar active regions (ARs). Calculation is expedient and practical, using only a single vector magnetogram per computation. We apply this method to a timeseries of 600 high-cadence vector magnetograms of the eruptive NOAA AR 11158 acquired by the Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory over a five-day observing interval. Besides testing our method extensively, we use it to interpret the dynamical evolution in the AR, including eruptions. We find that the AR builds large budgets of both free magnetic energy and relative magnetic helicity, sufficient to power many more eruptions than the ones it gave within the interval of interest. For each of these major eruptions, we find eruption-related decreases and subsequent free-energy and helicity budgets that are consistent with the observed eruption (flare and coronal-mass-ejection [CME]) sizes. In addition, we find that (1) evolution in the AR is consistent with the recently proposed (free) energy - (relative) helicity diagram of solar ARs, (2) eruption-related decreases occur {\it before} the flare and the projected CME-launch times, suggesting that CME progenitors precede flares, and (3) self-terms of free energy and relative helicity most likely originate from respective mutual-terms, following a progressive mutual-to-self conversion pattern that most likely stems from magnetic reconnection. This results in the non-ideal formation of increasingly helical pre-eruption structures and instigates further research on the triggering of solar eruptions with magnetic helicity firmly placed in the eruption cadre.
A note on linearized "New Massive Gravity" in arbitrary dimensions

Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)

description: By means of a triple master action we deduce here a linearized version of the "New Massive Gravity" (NMG) in arbitrary dimensions. The theory contains a 4th-order and a 2nd-order term in derivatives. The 4th-order term is invariant under a generalized Weyl symmetry. The action is formulated in terms of a traceless $η^{μν}Ω_{μνρ}=0$ mixed symmetry tensor $Ω_{μνρ}=-Ω_{μρν}$ and corresponds to the massive Fierz-Pauli action with the replacement $e_{μν}=\p^ρΩ_{μνρ}$. The linearized 3D and 4D NMG theories are recovered via the invertible maps $Ω_{μνρ} = ε_{νρ}^{\quadβ}h_{βμ} $ and $Ω_{μνρ} = ε_{νρ}^{\quad γδ}T_{[γδ]μ} $ respectively. The properties $h_{μν}=h_{νμ}$ and $T_{[[γδ]μ]}=0$ follow from the traceless restriction. The equations of motion of the linearized NMG theory can be written as zero "curvature" conditions $\p_νT_{ρμ} - \p_ρT_{νμ}=0$ in arbitrary dimensions.

Variational Formulation of Curved Beams in Global Coordinates

Publisher: name: arXiv
Year: 2013
Subjects: subject: Numerical Analysis (math.NA)

description: In this paper we derive a variational formulation for a linear curved beam which is natively expressed in global Cartesian coordinates. During derivation the beam midline is assumed to be implicitly described by a vector distance function which eliminates the need for local coordinates. The only geometrical information appearing in the final expressions for the governing equations is the tangential direction, and thus there is no need to introduce normal directions along the curve. As a consequence zero or discontinuous curvature, for example at inflection points, pose no difficulty in this formulation. Kinematic assumptions encompassing both Timoshenko and Euler--Bernoulli beam theories are considered. With the exception of truly three dimensional formulations, models for curved beams found in literature are typically derived in the Frenet frame defined by the geometry of the beam midline. While it is intuitive to formulate curved beam models in these local coordinates, the Frenet frame suffers from ambiguity and sudden changes of orientation in straight sections of the beam. Based on the variational formulation we implement finite element models using global Cartesian degrees of freedom and discuss curvature coupling effects and locking. Numerical comparisons with classical solutions for both straight and curved cantilever beams under a tip load are given, as well as numerical examples illustrating curvature coupling effects.

We review the theoretical foundations of PDF determination: the way cross sections are expressed in terms of PDFs using perturbative QCD factorization and evolution, the methodology used to extract PDFs from experimental data, and the way in which different physical processes can be used to constrain different PDFs. We summarize current knowledge of PDFs and the limitations in accuracy currently entailed for the computation of hadron collider processes, in particular at the LHC. We discuss the current main sources of theoretical and phenomenological uncertainties, and the direction of progress towards their reduction in the future.

description: Agricultural decision support systems (DSSs) are hardware and software tools that utilize big data collected from satellites and drones, ground-based sensors, and analyzed with machine learning algorithms to provide site-specific farming recommendations. Despite the promise of DSSs to address many challenges of the farm economy, there are social and ethical concerns that need to be addressed. Utilizing a mixed-methods approach that consisted of focus group discussions and a follow-up survey questionnaire, we highlight the experiences and affectations of heterogeneous food system actors from Vermont and South Dakota. We find that DSSs transform agricultural knowledge production, reconfigure labor arrangements and unevenly distribute benefits and burdens among farmers. We suggest that agritech developers implement inclusive and deliberative processes when redesigning DSSs to engender ethical, equitable and sustainable improvements to food production systems. Inclusive processes of open deliberation are modalities of responsible innovation, tasked with mitigating frictions within socio-technical systems.

description: Using the QCD sum rule with its operator product expansion reliably estimated from lattice calculations for the pressure and energy density of the quark-gluon plasma, we calculate the strength of the wave function of J/psi at the origin and find that it decreases with temperature above the transition temperature. This result is shown to follow exactly that obtained from the solution of the Schrödingier equation for a charm and anticharm quark pair using the free energy from lattice calculations as the potential and is in sharp contrast to that using the deeper potential associated with the internal energy, which shows an enhanced strength of the J/psi wave function at the origin. Our result thus has resolved the long-standing question of whether the free energy potential or the internal energy potential should be used in analyzing the spectrum of heavy quark systems at finite temperature.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: This paper is devoted to check validity of the laws of thermodynamics for LRS Bianchi type I universe model which is filled with combination of dark matter and dark energy. We take two types of dark energy models, i.e., generalized holographic dark energy and generalized Ricci dark energy. It is proved that the first and generalized second law of thermodynamics are valid on the apparent horizon for both the models. Further, we take fixed radius $L$ of the apparent horizon with original holographic or Ricci dark energy. We conclude that the first and generalized second laws of thermodynamics do not hold on the horizon of fixed radius $L$ for both the models.

description: Tracing the historical emergence of academic/policy discourses shines a light on processes of early institutionalisation, informs narratives of contemporary self-identity and provides a resource from which to imagine alternative futures. Contributing to this ambition our paper uses scientometric methods to undertake two socio-semantic analyses. First, we identify the de-facto origins and contemporary clustering of scientists’ discursive spaces of ‘responsibility’. This ‘rri corpus’ reveals seven distinct clusters – or discourse coalitions of responsibility – but shows limited cross-fertilisation between the clusters. Second we trace the emergence of European policy on ‘Responsible Research and Innovation’ (RRI). The ‘RRI corpus’ shows policy to have been dominated by a small number of actors. Some cross-over between rri and RRI provides evidence of discourse coalition building, but only a small group of actors occupy these strategic bridges. The paper offers a contribution to wider debates and strategic reflections on the past, present and futures of responsible innovation.

Non-Abelian T-duality and the AdS/CFT correspondence:new N=1 backgrounds

description: We consider non-Abelian T-duality on N=1 supergravity backgrounds possessing well understood field theory duals. For the case of D3-branes at the tip of the conifold, we dualise along an SU(2) isometry. The result is a type-IIA geometry whose lift to M-theory is of the type recently proposed by Bah et. al. as the dual to certain N=1 SCFT quivers produced by M5-branes wrapping a Riemann surface. In the non-conformal cases we find smooth duals in massive IIA supergravity with a Romans mass naturally quantised. We initiate the interpretation of these geometries in the context of the AdS/CFT correspondence. We show that the central charge and the entanglement entropy are left invariant by this dualisation. The backgrounds suggest a form of Seiberg duality in the dual field theories which also exhibit domain walls and confinement in the infrared.

description: Groundnut is among the most valuable crops in Tanzania. It is a good source of oil, food, and income to many households however, it is considered a labor-intensive crop. Farmers perform tedious and laborious activities during ploughing, planting, weeding, harvesting, and shelling just to mention a few. Therefore, in ensuring that groundnut production achieves its potential within and outside the country, the introduction and use of labor- saving technologies cannot be overemphasized. This study intended to assess the farmers perception on groundnut labor-saving technologies in Tanzania. Specifically, the study aimed at (i) analyzing the labor-saving technologies used by groundnut farmers; (ii) Investigating farmers perception on the LSTs. Also, (iii) Comparing the farmers’ resource (such as time and finances) use associated with the traditional tools versus the labor-saving technologies (LST) and (iv) Discussing policy environment for labor saving technology in Tanzania.

description: In this research, by applying the extended Sturm-Liouville theorem for symmetric functions, a basic class of symmetric orthogonal polynomials (BCSOP) with four free parameters is introduced and all its standard properties, such as a generic second order differential equation along with its explicit polynomial solution, a generic orthogonality relation, a generic three term recurrence relation and so on, are presented. Then, it is shown that four main sequences of symmetric orthogonal polynomials can essentially be extracted from the introduced class. They are respectively the generalized ultraspherical polynomials, generalized Hermite polynomials and two other sequences of symmetric polynomials, which are finitely orthogonal on (-inf,inf) and can be expressed in terms of the mentioned class directly. In this way, two half-trigonometric sequences of orthogonal polynomials, as special sub-cases of BCSOP, are also introduced.

description: We present an analysis of the dynamics of the equifacial pentahedron on the Kapovich-Millson phase space under a volume preserving Hamiltonian. The classical dynamics of polyhedra under such a Hamiltonian may arise from the classical limit of the node volume operators in loop quantum gravity. The pentahedron is the simplest nontrivial polyhedron for which the dynamics may be chaotic. We consider the distribution of polyhedral configurations throughout the space and find indications that the borders between certain configurations act as separatrices. We examine the local stability of trajectories within this phase space and find that locally unstable regions dominate although extended stable regions are present. Canonical and microcanonical estimates of the Kolmogorov-Sinai entropy suggest that the pentahedron is a strongly chaotic system. The presence of chaos is further suggested by calculations of intermediate time Lyapunov exponents which saturate to non zero values.
