description: In this paper we present the package S@M (Spinors@Mathematica) which implements the spinor-helicity formalism in Mathematica. The package allows the use of complex-spinor algebra along with the multi-purpose features of Mathematica. The package defines the spinor objects with their basic properties along with functions to manipulate them. It also offers the possibility of evaluating the spinorial objects numerically at every computational step. The package is therefore well suited to be used in the context of on-shell technology, in particular for the evaluation of scattering amplitudes at tree- and loop-level.

description: Recent data from heavy ion collisions at RHIC show unexpectedly large near-angle correlations that broaden longitudinally with increasing centrality. The amplitude of this ridge-like correlation rises rapidly, reaches a maximum, and then falls in the most central collisions. In this letter we explain how this behavior can be explained as initial-state coordinate-space anisotropies converted into final-state momentum-space correlations. We propose $v_n^2/ε_{n,\mathrm{part}}^{2}$ as a useful way to study length scales and provide a prediction for the ridge in Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}=$ 2.76 TeV.

description: Unveiling intrinsic spins of propagating waves usually offers people a fundamental understanding of the geometrical and topological properties of waves from classical to quantum aspects. A great variety of research has shown that transverse waves can possess non-trivial quantum spins and topology without help of strong wave-matter interaction. However, until now we still lack essential physical insights about the spin and topological nature of longitudinal waves. Here, demonstrated by elastic waves we uncover unique quantum spins for longitudinal waves and the mixed longitudinal-transverse waves that play essential roles in topological spin-momentum locking. Based on this quantum spin perspective, several abnormal phenomena beyond pure transverse waves are attributed to the hybrid spin induced by mixed longitudinal-transverse waves. The intrinsic hybrid spin reveals the complex spin essence in elastic waves and advances our understanding about their fundamental topological properties. We also show these spin-dependent phenomena can be exploited to control the wave propagation, such as non-symmetric elastic wave excitation by spin pairs, uni-directional Rayleigh wave and spin-selected elastic wave routing. These findings are generally applicable for arbitrary waves with longitudinal and transverse components.

description: We describe the time- and position-dependent point spread function (PSF) variation of the Wide Field Channel (WFC) of the Advanced Camera for Surveys (ACS) with the principal component analysis (PCA) technique. The time-dependent change is caused by the temporal variation of the $HST$ focus whereas the position-dependent PSF variation in ACS/WFC at a given focus is mainly the result of changes in aberrations and charge diffusion across the detector, which appear as position-dependent changes in elongation of the astigmatic core and blurring of the PSF, respectively. Using >400 archival images of star cluster fields, we construct a ACS PSF library covering diverse environments of the $HST$ observations (e.g., focus values). We find that interpolation of a small number ($\sim20$) of principal components or ``eigen-PSFs'' per exposure can robustly reproduce the observed variation of the ellipticity and size of the PSF. Our primary interest in this investigation is the application of this PSF library to precision weak-lensing analyses, where accurate knowledge of the instrument's PSF is crucial. However, the high-fidelity of the model judged from the nice agreement with observed PSFs suggests that the model is potentially also useful in other applications such as crowded field stellar photometry, galaxy profile fitting, AGN studies, etc., which similarly demand a fair knowledge of the PSFs at objects' locations. Our PSF models, applicable to any WFC image rectified with the Lanczos3 kernel, are publicly available.

description: The recently proposed participant dissipating effective-energy approach is applied to describe the dependence on centrality of the multiplicity of charged particles measured in heavy-ion collisions at the collision energies up to the highest LHC energy of 5 TeV. The effective-energy approach relates multihadron production in different types of collisions, by combining, under the proper collision energy scaling, the constituent quark picture with Landau relativistic hydrodynamics. The measurements are shown to be well described in terms of the centrality-dependent effective energy of participants and an explanation of the differences in the measurements at RHIC and LHC are given by means of the recently introduced hypothesis of the energy-balanced limiting fragmentation scaling. A similarity between the centrality data and the data from most central collisions is proposed pointing to the central character of participant interactions independent of centrality. The findings complement our recent investigations of the similar midrapidity pseudorapidity density measurements extending the description to the full pseudorapidity range in view of the considered similarity of multihadron production in nucleon interactions and heavy-ion collisions.

description: Children's understanding of density is riddled with misconceptions—or so it seems. Yet even preschoolers at times appear to understand density. This article seeks to reconcile these conflicting outcomes by investigating the nature of constraints available in different experimental protocols. Protocols that report misconceptions about density used stimulus arrangements that make differences in mass and volume more salient than differences in density. In contrast, protocols that report successful performance used stimulus arrangements that might have increased the salience of density. To test this hypothesis, the present experiments manipulate the salience of object density. Children between 2 and 9 years of age and adults responded whether an object would sink or float when placed in water. Results indicated that children's performance on exactly the same objects differed as a function of the saliency of the dimension of density, relative to the dimensions of mass and volume. These results support the idea that constraints—rather than stable knowledge—drive performance, with implications for teaching children about nonobvious concepts such as density.

description: The central aim of this work is to understand rough differential equations on homogeneous spaces. We focus on the formal approach, by giving an explicit expansion of the solution at each point of the real line in terms of decorated planar forests. For this we develop the notion of planarly branched rough paths, following M. Gubinelli's branched rough paths. The definition is similar to the one in the flat case, the main difference being the replacement of the Butcher--Connes--Kreimer Hopf algebra of non-planar rooted forests by the Munthe-Kaas--Wright Hopf algebra of planar rooted forests. We show how the latter permits to handle rough differential equations on homogeneous spaces using planarly branched rough paths, the same way branched rough paths are used in the context of rough differential equations on finite-dimensional vector spaces. An analogue of T. Lyons' extension theorem is proven. Finally, under analyticity assumptions on the coefficients and when the Hölder index of the driving path is equal to one, we show convergence of the planar forest expansion in a small time interval.

EFFICIENCY AND APPLICATION OF ALTERNATIVE LOW COST CONSTRUCTION TECHNOLOGIES IN BUILDING PROJECTS: THE CASE OF ADDIS ABABA
Creators: name: Kefyalew Agergzat
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019
Subjects: Application, Efficiency, Low-cost, Sustainable, Technologies,

description: Economic factors have influence the construction industry dramatically in recent years
 and in many parts of the world, construction materials are scarce and expensive. The
 people live in Addis Ababa city suffer for an increasing shortage of house. Low-income
 group of people live in the city are incapable to modify and construct new home by using
 conventional construction materials technologies due to the costs of materials.
 Government efforts to eliminate the problem have not been successful due to materials
 cost escalation and other factor. Many researchers are searching for low-cost materials
 as a substitute or alternative for the present situation, but these technologies are not
 applying in building construction sectors. To study the reason behind why these
 alternative low cost materials technologies are not applying in the building sectors, the
 study assessed efficient and application alternative low cost construction technologies in
 building sectors. To assessed this study, the study utilized both primary (Performa
 questionnaires, interview, observation and content analysis) and secondary (literature
 reviews) data. Descriptive statistics used to analyze the collected data. This study finds that
 alternative low cost materials technologies are sustainable in the building sectors. The raw
 materials are locally readily available. The amount of energy conceptions are low when
 compere to conventional building technologies. The costs of alternative building technologies
 are reasonable. By combining alternative materials technologies with conventional building
 materials technologies for different components of the building, the overall cost and total
 project duration decrease by 13.14% and 20.53% respectively. Unluckily the biggest
 challenge facing the wide spread use of alternative low-cost construction technologies in
 building sectors today is primarily not sustainability but largely due to lack of
 governmental support, lack of promotion about the technologies, lack of standards and
 specifications, and also lack of information by the general public about the technologies.
 In General, alternative low cost technologies are sustainable, quite economical, durable
 and safe in low-rise building construction.

We show that this class encompasses the Haar measure-preserving transformations defined by ${\mathcal C}^1$ (in particular, polynomial) maps, and prove a structure theorem for locally scaling transformations. We use the theory of polynomial approximation on compact-open subsets of non-archimedean local fields to demonstrate the existence of ergodic Markov, and mixing Markov transformations defined by such polynomial maps. We also give simple sufficient conditions on the Mahler expansion of a continuous map $\mathbb Z_p \to \mathbb Z_p$ for it to define a Bernoulli transformation.

Nonlinear water waves in shallow water in the presence of constant vorticity: A Whitham approach
Creators: name: Kharif, Christian

Publisher: name: arXiv
Year: 2018
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Two-dimensional nonlinear gravity waves travelling in shallow water on a vertically sheared current of constant vorticity are considered. Using Euler equations, in the shallow water approximation, hyperbolic equations for the surface elevation and the horizontal velocity are derived. Using Riemann invariants of these equations, that are obtained analytically, a closed-form nonlinear evolution equation for the surface elevation is derived. A dispersive term is added to this equation using the exact linear dispersion relation. With this new single first-order partial differential equation, vorticity effects on undular bores are studied. Within the framework of weakly nonlinear waves, a KdV-type equation and a Whitham equation with constant vorticity are derived from this new model and the effect of vorticity on solitary waves and periodic waves is considered. Futhermore, within the framework of the new model and the Whitham equation a study of the effect of vorticity on the breaking time of dispersive waves and hyperbolic waves as well is carried out.

description: We consider a Josephson junction built with the two-dimensional semi-Dirac semimetal, which features a hybrid of linear and quadratic dispersion around a nodal point. We model the weak link between the two superconducting regions by a Dirac delta potential because it mimics the thin-barrier-limit of a superconductor-barrier-superconductor configuration. Assuming a homogeneous pairing in each region, we set up the BdG formalism for electronlike and holelike quasiparticles propagating along the quadratic-in-momentum dispersion direction. This allows us to compute the discrete bound-state energy spectrum $\varepsilon $ of the subgap Andreev states localized at the junction. In contrast with the Josephson effect investigated for propagation along linearly dispersing directions, we find a pair of doubly degenerate Andreev bound states. Using the dependence of $\varepsilon $ on the superconducting phase difference $ϕ$, we compute the variation of Josephson current as a function of $ϕ$.

Subjects: Healthcare centers, Security and Privacy framework, E-health information system, encryption

description: Security and privacy play a vital role in healthcare institutions’ day-to-day activity to ensure
 health data is adequately safe and protected. The current IT infrastructure provided by many
 healthcare centers lacks structural security and privacy elements, like security devices, welltrained employees in the centers which could be installed in the healthcare centers.
 This study attempts to design data security and privacy of healthcare centers mainly found in
 Addis Ababa city including both public and private health centers. Most of the Ethiopian
 healthcare centers are keeping their confidential records in a manual way. Records of patients,
 healthcare centers and other communication letters that are shared with other centers need
 privacy and security. However, nowadays there is no clear framework used to share health
 information among healthcare centers, which the current study targeted to deal with.
 The current study has been conducted based on the design science research process. Problems
 were identified using surveys conducted by distributing questionnaires to the health institutions.
 The collected data were analyzed and interpreted to define the problem and motivate the need to
 design a framework. This stage leads the researcher to define the system requirement and design
 the system framework. The prototype is implemented using the JAVA programming language.
 The prototype is needed to be integrated into the e-health system that currently used by the
 healthcare centers. Finally, the porotype is tested by users and evaluated by health information
 professionals from selected healthcare centers. The result is encouraging to fully implement as
 per the identified requirements. There have been some challenges like the designed prototype
 needs enhanced E-health system, in which the healthcare centers should adopt cloud computing
 for better application of designed systems. Researchers and scholars will take this research as a
 turning point to investigate further on security and privacy of health data.

description: If there is CPT violation, the nature of entanglement for neutral meson pairs produced in meson factories may, on general grounds, be affected. The new form of entanglement is the omega effect. Gravitational decoherence, due to space-time foam, may be one route for deviations from CPT invariance. Two models of space-time foam are considered. One, based on non-critical string theory, is able to produce the new correlations in a natural way. The other, based on the paradigm of thermal-like baths, is shown to be surprisingly resistant to producing the effect even on exercising a total freedom of choice for the state of the bath

Monsieur,

J'ai différé de répondre à l'honneur de la vôtre jusqu'au retour de voyage de M. Mouret afin qu'il fut porteur de la lettre comme il l'avait été du paquet des papiers de M. Pellerin, lequel il m'a remis en bon état. Je suis charmé que vous y ayez trouvé de quoi s'amuser. Il est vrai qu'il y a toujours beaucoup à profiter sa correspondance. Je suis après lire son dernier ouvrage en trois volumes dont le style concis est marqué au coin d'une érudition peu commune. Des hommes de cette trempe devraient être éternels. J'ai reçu de ses nouvelles hier au soir. Il n'a pas encore reçu les médailles qui lui viennent du Levant en quantité, puisque c'est la récolte de tout le temps qu'a duré la guerre. Il est à souhaiter qu'elles arrivent à temps pour enrichir son 5e volume qu'il se propose de donner.

Vous avez bien raison de vous consoler de nos ardoises. Celle que vous avez bien voulue me donner est très belle. Le relief qu'on lui a donné par le burin fait un joli effet. Je n'ai rien remarqué de plus particulier dans toutes celles de nos pays qui m'ont passé ci-devant par devant. Elles représentent pareillement de la fougère, quelques fois d'autres petites plantes et très rarement des feuilles de jonc. Parmi quatre personnes de Saint Chaumont qui en ont promis au Père Rousset aucune n'a encore exécuté sa parole, se retranchant sur ce qu'ils ne trouvent que de petits morceaux. Ayons donc encore un peu de patience. J'ai remis chez Mrs Perrin et Carmagnac chargeurs votre boîte destinée pour Yene [Iena] en Thuringe. Le P. Rousset vous présente ses compliments.

[fol. 21 v] M. Soubry est encore à sa campagne. Je ne manquerai pas de lui parler de votre commission des héliotropes. Je ne suis point surpris qu'ils aient manqué de lever, cette graine étant des plus délicates. Cela m'est aussi arrivé et à M. Poivre. J'étais enfin parvenu à en avoir 2 plantes que l'hiver a fait mourir de même qu'une douzaine qu'en avait M. Poivre, de sorte que je n'en sache aucune plante ici vivante. Elles étaient cependant toutes venues de graine, dans une terre préparée et passée au tamis qu'il rafraîchissait par la toile ou une couche de paille. Il en a semé cette année et aucun n'a encore levé. Peut-être le fera-t-elle dans l'arrière-saison.

J'ai l'honneur d'être avec un profond respect,

Monsieur,

Votre très humble et très obéissant serviteur

We prove that the Nijenhuis torsion of a skew-symmetric endomorphism N of a Courant algebroid is skew-symmetric if the square of N is proportional to the identity, and only in this case when the Courant algebroid is irreducible. We derive a necessary and sufficient condition for a skew-symmetric endomorphism to give rise to a deformed Courant structure. In the case of the double of a Lie bialgebroid (A,A*), given an endomorphism n of A that defines a skew-symmetric endomorphism N of the double of A, we prove that the torsion of N is the sum of the torsion of n and that of the transpose of n.

description: Simplicity bias is an intriguing phenomenon prevalent in various input-output maps, characterized by a preference for simpler, more regular, or symmetric outputs. Notably, these maps typically feature high-probability outputs with simple patterns, whereas complex patterns are exponentially less probable. This bias has been extensively examined and attributed to principles derived from algorithmic information theory and algorithmic probability. In a significant advancement, it has been demonstrated that the renowned logistic map and other one-dimensional maps exhibit simplicity bias when conceptualized as input-output systems. Building upon this work, our research delves into the manifestations of simplicity bias within the random logistic map, specifically focusing on scenarios involving additive noise.
 We discover that simplicity bias is observable in the random logistic map for specific ranges of $μ$ and noise magnitudes. Additionally, we find that this bias persists even with the introduction of small measurement noise, though it diminishes as noise levels increase. Our studies also revisit the phenomenon of noise-induced chaos, particularly when $μ=3.83$, revealing its characteristics through complexity-probability plots. Intriguingly, we employ the logistic map to illustrate a paradoxical aspect of data analysis: more data adhering to a consistent trend can occasionally lead to \emph{reduced} confidence in extrapolation predictions, challenging conventional wisdom.
 We propose that adopting a probability-complexity perspective in analyzing dynamical systems could significantly enrich statistical learning theories related to series prediction and analysis. This approach not only facilitates a deeper understanding of simplicity bias and its implications but also paves the way for novel methodologies in forecasting complex systems behavior.

description: We resolve the long-standing controversy over the surface energy of simple metals: Density functional methods that require uniform-electron-gas input agree with each other at many levels of sophistication, but not with high-level correlated calculations like Fermi Hypernetted Chain and Diffusion Monte Carlo (DMC) that predict the uniform-gas correlation energy. Here we apply a very high-level correlated approach, the inhomogeneous Singwi-Tosi-Land-Sjölander (ISTLS) method, and find that the density functionals are indeed reliable (because the surface energy is "bulk-like"). ISTLS values are close to recently-revised DMC values. Our work also vindicates the previously-disputed use of uniform-gas-based nonlocal kernels in time-dependent density functional theory.

The length scales (of a few nanometers) involved in the experimental setups prompt us to consider an infinitely periodic system of two-dimensionally confined (InAs) quantum dot layers separated by GaAs spacers. The the Bloch functions and the Hermite functions together characterize the whole system. We then make use of the Bohm-Pines' (full) random-phase approximation in order to derive a general nonlocal, dynamic dielectric function. Thus developed theoretical framework is then specified to work within a (lowest miniband and) two-subband model that enables us to scrutinize the single-particle as well as collective responses of the system. We compute and discuss the behavior of the eigenfunctions, band-widths, density of states, Fermi energy, single-particle and collective excitations, and finally size up the importance of studying the inverse dielectric function in relation with the quantum transport phenomena. It is remarkable to notice how the variation in the barrier- and well-widths can allow us to tailor the excitation spectrum in the desired energy range. Given the advantage of the vertically stacked quantum dots over the planar ones and the foreseen applications in the single-electron devices and in the quantum computation, it is quite interesting and important to explore the electronic, optical, and transport phenomena in such systems.

description: The change in energy of an ideal Fermi gas when a local one-body potential is inserted into the system, or when the density is changed locally, are important quantities in condensed matter physics. We show that they can be rigorously bounded from below by a universal constant times the value given by the semiclassical approximation.

Lean on Me: Establishing a Grassroots Peer Support Program on Campus and the Meaning Volunteers Experienced
Creators: name: Myers, Zed-Ola
Publisher: name: Capilano University

description: With student anxiety disorders on the rise globally and drastically low rates of seeking professional help of a counsellor by this age cohort, an intermediary step is needed to destigmatize conversations about mental health. Peer-support has been proven to be an excellent resource to fill this gap. Empirical studies have shown that engaging in peer support has reciprocal benefits for the peer and supporter with increased rates of positive coping, empowerment and self-efficacy. This study investigated the experiences of student volunteers who engaged in peer-support training workshops on campus and the meaning that they experienced as a result. The investigation was conducted with a qualitative approach through reflexive thematic analysis and phenomenological framework. It was noted in the accounts of the participants that in-person active listening role-playing resulted in development of soft skills such as empathy, warmth and sincerity. The findings demonstrated that acting in the role of peer-supporter is much like being a friend...but not quite. The peer-supporter role is one that requires balance between professionalism and casual interaction, boundary setting and relationality. The skills developed through the workshops – communication and leadership skills, problem solving, and increased confidence in community engagement – provided a good complement to the psychology curriculum through hands-on and in-person practical application. The added benefit was the sense of community that came as a result of working towards a common goal, increasing the student wellbeing on campus.

description: We consider the possibility to solve the issues of the phantom field cosmology by means of the PT-symmetric quantum theory. The Born-Oppenheimer approximation is applied to the Wheeler-DeWitt equation to study the inhomogeneous fluctuations over the homogeneous minisuperspace. The evolution of the longitudinal inhomogeneous modes in WKB-time is described using a time-dependent pseudo-Hermitian effective Hamiltonian.

description: Electrons in double-layer semiconductor heterostructures experience a special type of spin-orbit interaction which arises in each layer from the perpendicular component of the Coulomb electric field created by electron density fluctuations in the other layer. We show that this interaction, acting in combination with the usual spin-orbit interaction, can generate a spin current in one layer when a charge current is driven in the other. This effect is symmetry-wise distinct from the spin Hall drag. The spin current is not, in general, perpendicular to the drive current.

description: Advances in sequencing techniques have led to exponential growth in biological data, demanding the development of large-scale bioinformatics experiments. Because these experiments are computation- and data-intensive, they require high-performance computing (HPC) techniques and can benefit from specialized technologies such as Scientific Workflow Management Systems (SWfMS) and databases. In this work, we present BioWorkbench, a framework for managing and analyzing bioinformatics experiments. This framework automatically collects provenance data, including both performance data from workflow execution and data from the scientific domain of the workflow application. Provenance data can be analyzed through a web application that abstracts a set of queries to the provenance database, simplifying access to provenance information. We evaluate BioWorkbench using three case studies: SwiftPhylo, a phylogenetic tree assembly workflow; SwiftGECKO, a comparative genomics workflow; and RASflow, a RASopathy analysis workflow. We analyze each workflow from both computational and scientific domain perspectives, by using queries to a provenance and annotation database. Some of these queries are available as a pre-built feature of the BioWorkbench web application. Through the provenance data, we show that the framework is scalable and achieves high-performance, reducing up to 98% of the case studies execution time. We also show how the application of machine learning techniques can enrich the analysis process.

description: We propose a trade-off between the Lipschitz constants of the position and momentum probability distributions for arbitrary quantum states. We refer to the trade-off as a quantum reciprocity relation. The Lipschitz constant of a function may be considered to quantify the extent of fluctuations of that function, and is, in general, independent of its spread. The spreads of the position and momentum distributions are used to obtain the celebrated Heisenberg quantum uncertainty relations. We find that the product of the Lipschitz constants of position and momentum probability distributions is bounded below by a number that is of the order of the inverse square of the Planck's constant.

description: We study the dynamical quasiparticle scattering by spin and charge fluctuations in Fe-based pnictides within a five-orbital model with on-site interactions. The leading contribution to the scattering rate is calculated from the second-order diagrams with the polarization operator calculated in the random-phase approximation. We find one-particle scattering rates which are highly anisotropic on each Fermi surface sheet due to the momentum dependence of the spin susceptibility and the multi-orbital composition of each Fermi pocket. This fact, combined with the anisotropy of the effective mass, produces disparity between electrons and holes in conductivity, the Hall coefficient, and the Raman initial slope, in qualitative agreement with experimental data.
