description: We study the dissipative dynamics of neutral atoms in anisotropic harmonic potentials, immersed in a reservoir species that is not trapped by the harmonic potential. Considering initial motional excitation of the atoms along one direction, we explore the resulting spontaneous emission of reservoir excitations, across a range of trap parameters from strong to weak radial confinement. In different limits these processes are useful as a basis for analogies to laser cooling, or as a means to introduce controlled dissipation to many-body dynamics. For realistic experimental parameters, we analyse the distribution of the atoms during the decay and determine the effects of heating arising from a finite temperature reservoir.

description: Background: Dengue occurs epidemically in Sri Lanka and every year, when the monsoon season begins, health authorities warn on rising numbers of dengue cases. The popular belief is that dengue epidemics are driven by the two monsoons which feed different parts of the country over different time periods. We analysed the time series of weekly dengue cases in all districts of Sri Lanka from 2007 to 2019 to identify the spatiotemporal patterns of dengue outbreaks and to explain how they are associated with the climatic, geographic and demographic variations around the country. Methods: We used time-series plots, statistical measures such a community-wide synchrony and Kendall-W and a time-varying graph method to understand the spatiotemporal patterns and links. Results and conclusions: The southwest wet zone and surrounding areas which receive rainfall in all four seasons usually experience two epidemic waves per year. The northern and eastern coastal region in the dry zone which receives rainfall in only two seasons experiences one epidemic wave per year. The wet zone is a highly synchronised epidemic unit while the northern and eastern districts have more independent epidemic patterns. The epidemic synchrony in the wet zone may be associated with the frequent mobility of people in and out of the wet zone hot spot Colombo. The overall epidemic pattern in Sri Lanka is not a sole outcome of the two monsoons but the regional epidemic patterns are collectively shaped by monsoon an inter-monsoon rains, human mobility, geographical proximity and other climate and topographical factors.

Redefinition of Saicini
Considering the phylogenetic results that help redefine the newly circumscribed Saicini, we use the optimization of the characters from our analyses to complement and modify the diagnosis offered by Standring et al. (2023), propose two new subtribes, and give a diagnosis for each genus. Furthermore, we present for the first time a key to the genera of Saicini of the world.

description: In this study, the multi-objective optimal design of functionally graded material flywheels is obtained using the non-dominated sorting genetic algorithm-II. The variations in temperature along the flywheel radius due to the operating conditions and environmental changes are taken into consideration in design optimization. Variations in the elastic and thermal properties of materials with temperature are taken into consideration for the first time, to the best of the authors’ knowledge. The thermoelastic equations of motion and the heat equation are derived and then solved by the generalized differential quadrature method. Results for temperature variation, radial displacement and von Mises stress are compared with the results of finite element analysis, and very good agreement is observed. Designs with optimal cross-sectional geometry and material distribution that give minimum mass and maximum kinetic energy are obtained.

description: Drawing is the initial act of architecture. Line drawing has become an anthropogenic tool for architects to understand and record the world, yet these lines rarely occur in natural phenomena. To be better equipped to represent spaces that are beyond the human, this exploration seeks to reframe architectural drawing in relation to the geologic and ecologic forces of the earth, matter which is usually considered outside the concern of the field of architecture. This project explores the spatial ecologies of the karst forest ecosystems on Vancouver Island, testing architectural drawing conventions that learn from karsts, and become fluid in their depiction of edge, scale, and time.
Global Aspects of Spaces of Vacua

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study "vacuum crossing", which occurs when the vacua of a theory are exchanged as we vary some periodic parameter $θ$ in a closed loop. We show that vacuum crossing is a useful non-perturbative tool to study strongly-coupled quantum field theories, since finding vacuum crossing in a weakly-coupled regime of the theory can lead to nontrivial consequences in the strongly-coupled regime. We start by discussing a mechanism where vacuum crossing occurs due to an anomaly, and then discuss some applications of vacuum crossing in general. In particular, we argue that vacuum crossing can be used to check IR dualities and to look for emergent IR symmetries.

description: We report the results of XMM-Newton observations of the X-ray bright, radio-loud blazar GB B1428+4217 at a redshift of z=4.72. We confirm the presence of soft X-ray spectral flattening at energies <0.7 keV as reported in previous ROSAT and BeppoSAX observations. At hard X-ray energies the spectrum is consistent with a power-law although we find the spectral slope varied between both XMM-Newton observations and is also significantly different from that reported previously. Whilst we cannot rule-out intrinsic cold absorption to explain the spectral depression, we favour a dust-free warm absorber. Cold absorption requires a column density ~1.4-1.6 x 10^22 cm^-2 whilst a warm absorber could have up to ~10^23 cm^-2 and an ionization parameter ~10^2. The spectrum of GB B1428+4217 shows remarkable parallels with that of the z=4.4 blazar PMN J0525-3343, in which the available evidence is also most consistent with a warm absorber model.

description: Reconstructing high-quality magnetic resonance images (MRI) from undersampled raw data is of great interest from both technical and clinical point of views. To this date, however, it is still a mathematically and computationally challenging problem due to its severe ill-posedness, resulting from the highly undersampled data leading to significantly missing information. Whilst a number of techniques have been presented to improve image reconstruction, they only account for spatio-temporal regularisation, which shows its limitations in several relevant scenarios including dynamic data. In this work, we propose a new mathematical model for the reconstruction of high-quality medical MRI from few measurements. Our proposed approach combines - \textit{in a multi-task and hybrid model} - the traditional compressed sensing formulation for the reconstruction of dynamic MRI with motion compensation by learning an optical flow approximation. More precisely, we propose to encode the dynamics in the form of an optical flow model that is sparsely represented over a learned dictionary. This has the advantage that ground truth data is not required in the training of the optical flow term. Furthermore, we present an efficient optimisation scheme to tackle the non-convex problem based on an alternating splitting method. We demonstrate the potentials of our approach through an extensive set of numerical results using different datasets and acceleration factors. Our combined approach reaches and outperforms several state of the art techniques. Finally, we show the ability of our technique to transfer phantom based knowledge to real datasets.

description: We present a calculation of the standard model ΔS=2 matrix element relevant to indirect CP violation in K->ππdecays which uses Neuberger's chiral formulation of lattice fermions. The computation is performed in the quenched approximation on a 16^3x32 lattice that has a lattice spacing a\sim 0.1 fm. The resulting bare matrix element is renormalized non-perturbatively. Our main result is B_K^{RGI}=0.87(8)^{+2+14}_{-1-14}, where the first error is statistical, the second is systematic and the third is an estimate of the uncertainty associated with the quenched approximation and with the fact that our kaons are composed of degenerate s and d quarks with masses \sim m_s/2.

The Influence of Scholarly Output on Scientific Dataset Communication
Creators: name: Chao, Tiffany
Publisher: name: Zenodo
Year: 2012

description: Research datasets possess enduring value beyond their originally designed purpose, especially as they typically will never be analyzed or utilized to their fullest potential within a given project time frame. The extent of dataset reuse as a mechanism to understand long-term usefulness within and beyond formal channels of scholarly communication, is an area where further investigation is needed particularly in relation to domain-based and subdiscipline differences. Based on the use metric categories and publication types presented by the Inter-university Consortium for Political and Social Research (ICPSR) for the dissemination of social science-themed datasets, this study presents a parallel analysis of the distribution of traditional and non-traditional publications affiliated with publicly available datasets in the atmospheric sciences. These affiliated publications are works identified by the dataset creator related to a dataset and includes a variety of items such as peer-reviewed journal articles, technical reports, and theses. Preliminary results reveal the potential audiences and communities that dataset contributors reach through selection of publication type and quantity. As the boundaries of scholarly communication are continually pushed by the visibility and intellectual power of scientific datasets, a clearer understanding of their lasting value and extensive influence takes shape.

Network Analysis of Data Reuse in the Social Sciences
Creators: name: Fear, Kathleen
Publisher: name: Zenodo
Year: 2012

description: Studies of the citation networks of scientific papers show that science is slowly but surely becoming more interdisciplinary: publications increasingly incorporate ideas from disciplines outside of the primary authors', and authors from different disciplines more frequently collaborate and co-author papers. Few, if any, studies, however, have distinguished between interdisciplinary collaboration or knowledge sharing and interdisciplinary data reuse. Given the significant barriers to data sharing and reuse that can arise even within a given discipline, it is possible that patterns of interdisciplinary data reuse differ somewhat from those of other kinds of interdisciplinarity. This paper examines patterns of interdisciplinary data reuse in the social sciences through a network analysis of data citation information from ICPSR. The results will offer insight for data producers and data managers in curating data to foster interdisciplinary reuse.
Data Sharing Across the Disciplines, Revisited: Academic Journals and Replication Policies. An Emperical Study
Creators: name: O'Reilly, Rob
Publisher: name: Zenodo
Year: 2012

description: Academics in the social sciences have long argued for increased sharing of research data as a means of increasing transparency and methodological rigor (see, for instance, the symposium on "Data Collection and Collaboration" in PS: Political Science Politics 43:1: http://dx.doi.org/10.1017/S1049096510990586). One oft-proposed means for encouraging data sharing is for academic journals for academic journals to encourage or require authors to make data publicly available as part of the publication process. But to what extent have journals heeded the call for replication policies? This presentation will re-visit prior work, presented at IASSIST 2009, that compared journals in Economics, Political Science, and Sociology in terms of presence or absence of policies requiring authors to make data available for replication purposes. Using updated data on a larger sample of journals, we will examine both the extent to which journals are adopting replication policies and whether such adoption varies across disciplines.

description: We study the spatiotemporal correlation of terrorist attacks by al-Qaeda, ISIS, and local insurgents, in six geographical areas identified via $k$-means clustering applied to the Global Terrorism Database. All surveyed organizations exhibit near-repeat activity whereby a prior attack increases the likelihood of a subsequent one by the same group within 20km and on average 4 (al Qaeda) to 10 (ISIS) weeks. Near-response activity, whereby an attack by a given organization elicits further attacks from a different one, is found to depend on the adversarial, neutral or collaborative relationship between the two. When in conflict, local insurgents respond quickly to attacks by global terror groups while global terror groups delay their responses to local insurgents, leading to an asymmetric dynamic. When neutral or allied, attacks by one group enhance the response likelihood of the other, regardless of hierarchy. These trends arise consistently in all clusters for which data is available. Government intervention and spill-over effects are also discussed; we find no evidence of outbidding. Understanding the regional dynamics of terrorism may be greatly beneficial in policy-making and intervention design.

The luc1 knockout strain accumulated demethylated analogs, indicating the involvement of Luc1 methyltransferase in lucilactaene biosynthesis. Lucilactaene showed potent antimalarial activity. Our data suggested that methylation and ether ring formation are essential for its potent antimalarial activity.
Comparative study of radio pulses from simulated hadron-, electron-, and neutrino-initiated showers in ice in the GeV-PeV range

description: High energy particle showers produce coherent Cherenkov radio emission in dense, radio-transparent media such as cold ice. Using PYTHIA and GEANT simulation tools, we make a comparative study among electromagnetic (EM) and hadronic showers initiated by single particles and neutrino showers initiated by multiple particles produced at the neutrino-nucleon event vertex. We include all the physics processes and do a complete 3-D simulation up to 100 TeV for all showers and to 1 PeV for electron and neutrino induced showers. We calculate the radio pulses for energies between 100 GeV and 1 PeV and find hadron showers, and consequently neutrino showers, are not as efficient below 1 PeV at producing radio pulses as the electromagnetic showers. The agreement improves as energy increases, however, and by a PeV and above the difference disappears. By looking at the 3-D structure of the showers in time, we show that the hadronic showers are not as compact as the EM showers and hence the radiation is not as coherent as EM shower emission at the same frequency. We show that the ratio of emitted pulse strength to shower tracklength is a function only of a single, coherence parameter, independent of species and energy of initiating particle.

description: Data has been closely related to all the e-research fields, be it e-science, e-social sciences or e-humanities. There are increasing amount of descriptive studies on the current data needs of different discipline, there are also best practices of data management developed with the mindset of taking care of data during its whole life cycle. But among all these hot discussions of the opportunities and challenges that data is bringing to the world, there haven't been enough philosophical thoughts or reflections on data's advantages and limitations under the consideration of the different goals of science, social sciences, and humanities' inquiries. This paper will start from Jürgen Habermas' epistemology of knowledge and human interests; then examine different e-research fields and their data usage trends with new theoretical lens of their ultimate missions, that is how well they have helped human beings instrumentally control the world, ideally change the society, and easily understand each other across temporal and spatial dimensions. We could then also have a higher level of vision about what might be possible in the future that data could help each research fields to accomplish.
Optimized Directed Roadmap Graph for Multi-Agent Path Finding Using Stochastic Gradient Descent

description: We present a novel approach called Optimized Directed Roadmap Graph (ODRM). It is a method to build a directed roadmap graph that allows for collision avoidance in multi-robot navigation. This is a highly relevant problem, for example for industrial autonomous guided vehicles. The core idea of ODRM is, that a directed roadmap can encode inherent properties of the environment which are useful when agents have to avoid each other in that same environment. Like Probabilistic Roadmaps (PRMs), ODRM's first step is generating samples from C-space. In a second step, ODRM optimizes vertex positions and edge directions by Stochastic Gradient Descent (SGD). This leads to emergent properties like edges parallel to walls and patterns similar to two-lane streets or roundabouts. Agents can then navigate on this graph by searching their path independently and solving occurring agent-agent collisions at run-time. Using the graphs generated by ODRM compared to a non-optimized graph significantly fewer agent-agent collisions happen. We evaluate our roadmap with both, centralized and decentralized planners. Our experiments show that with ODRM even a simple centralized planner can solve problems with high numbers of agents that other multi-agent planners can not solve. Additionally, we use simulated robots with decentralized planners and online collision avoidance to show how agents are a lot faster on our roadmap than on standard grid maps.

description: This article considers linear multi-objective programming problems with block angular structure, which are analogous to multi-disciplinary optimization environments where disciplines must collaborate to achieve a common overall goal. In this decentralized environment, a mechanism to guide locally optimized decision makers’ solutions to a Pareto-optimal solution without sharing the entire local information is developed. The mechanism is based on an augmented Lagrangian approach to generate a solution and is separated into two phases: phase I determines an ideal point for each of the single objectives and phase II searches for a compromise solution starting from a single ideal point. Theoretical results show that the algorithm converges and the solution generated is Pareto optimal. The algorithm’s effectiveness is demonstrated via an illustrative example and a real-world bi-objective re-entrant flow-shop production planning problem. The real-world experimental results showed that the decentralized method had an average 50% better performance compared to other centralized methods.

description: The main objective of this paper is to explore abundances of fluorine in hot Extreme Helium Stars (EHes). Overabundance of fluorine is a characteristic feature for cool EHes and R Coronae Borealis (RCB) stars and further enforces their close connection. For hot EHes this relationship with the cooler EHes, based on their fluorine abundance is unexplored. We present in this paper the first abundance estimates of fluorine determined from singly ionised fluorine lines (F\,{\sc ii}) for 10 hot EHe stars from optical spectra. Fluorine abundances were determined using the F\,{\sc ii} lines in two windows centered at 3505 Å\ and 3850 Å. Six of the 10 stars show significant enhancement of fluorine similar to the cool EHes. Two carbon-poor hot EHes show no signature of fluorine and have a significant low upper limit for the F abundance. These fluorine abundances are compared with the other elemental abundances observed in these stars which provide an idea about the formation and evolution of these stars. The trends of fluorine with C, O, and Ne show that significant helium burning after a CO-He white dwarf merger can account for a majority of the observed abundances. Predictions from simulations of white dwarf mergers are discussed in light of the observed abundances.

description: Topology optimization is an effective method in the design of acoustic media. This article presents optimization for graded damping materials to minimize sound pressure at a reference point or sound power radiation under harmonic excitation. The Helmholtz integral equation is used to calculate an acoustic field to satisfy the Sommerfeld conditions. The equation of motion is solved using a unit dynamic load method. Formulations for the sound pressure or sound power radiation in an integral form are derived in terms of mutual kinetic and strain energy densities. These integrals lead to novel physical response functions for solving the proposed optimization problem to design graded damping materials. The response function derived for individual frequency is utilized to solve the multi-objective optimization problem of minimizing sound pressure at the reference point for excitations with a range of frequencies. Numerical examples are presented to verify the efficiency of the present formulations.

description: We study an extension of the standard model with one latticized extra dimension accessible to all fields. The model is characterized by the size of the extra dimension and the number of sites, and contains a tower of massive particles. At energies lower than the mass of the new particles there are no tree-level effects. Therefore, bounds on the scale of new physics can only be set from one-loop processes. We calculate several observables sensitive to loop-effects, such as the $ρ$ parameter, $b\to s γ$, $Z\to b\bar b$, and the $B^0\rightleftharpoons\bar{B}^0$ mixing, and use them to set limits on the lightest new particles for different number of sites. It turns out that the continuous result is rapidly reached when the extra dimension is discretized in about 10 to 20 sites only. For small number of sites the bounds placed on the usual continuous scenario can be reduced by roughly a factor of 10%--25%, which means that the new particles can be as light as $320 {GeV}$. Finally, we briefly discuss an alternative model in which fermions do not have additional modes.

description: Business performance measurement plays a special role in improving the quality of decision-making and increasing overall business efficiency. Performance measurement provides the information about the state of an organization as a system, and on that basis, in the future, set realistic goals which will be challenging and stimulating. Without an objective, comprehensive, regular measurement of business performances, an organization would lose vital information for a continuous stream of business management decision making, without which there is no effective management (planning, organizing, leading and controlling). From the above mentioned, the importance of developing new, modern performance measurement system is gone, which should to overcome the disadvantages of the traditional financial measurement system, which is based solely on financial measures of performances. The aim of this paper is to highlight the characteristics of modern business performance measurement framework and presents only some of them. Introducing these new concepts and their effective implementation in organizations is in a function of the increasing the business efficiency.

description: We study the problem of secret key distillation from bipartite states in the scenario where Alice and Bob can only perform measurements at the single-copy level and classically process the obtained outcomes. Even with these limitations, secret bits can be asymptotically distilled by the honest parties from any two-qubit entangled state, under any individual attack. Our results point out a complete equivalence between two-qubit entanglement and secure key distribution: a key can be established through a one-qubit channel if and only if it allows to distribute entanglement. These results can be generalized to higher dimension for all those states that are one-copy distillable.

description: This study aimed to evaluate the protective role of paricalcitol, a vitamin D analog, against hazardous effects of 1800-MHz radiofrequency (RF) radiation on the skin of male Wistar albino rats exposed one h/day for 4 weeks. The maximum specific absorption rate was calculated as 0.0042 W/kg. Superoxide dismutase and catalase activity, collagen bundle thickness, breaking force, energy, and stress were decreased, while malondialdehyde level and mast cell number were increased. The exposure to 1800-MHz RF radiation caused a reduction in skin biomechanical quality through oxidative stress and mast cell activation. The administration of paricalcitol caused a significant improvement.

description: In this work we study static perfect fluid stars in 2+1 dimensions with an exterior BTZ spacetime. We found the general expression for the metric coefficients as a function of the density and pressure of the fluid. We found the conditions to have regularity at the origin throughout the analysis of a set of linearly independent invariants. We also obtain an exact solution of the Einstein equations, with the corresponding equation of state $p=p(ρ)$, which is regular at the origin.

description: At the end of the 80’s of last century began the trend of reducing the demand for mass tourism and there is a new form of demand for tourism products. Modern tourism demand is directed towards the so-called “6E” (experience, excitement, escape, education, entertaiment, ecology). This includes the development of a new concept of tourism that is based on the principles of sustainable development. This paper analyzes the role of mountain tourism in the changed conditions of the tourism market and the tendency of the modern mountain tourism.

description: Cluster organizations today are one of the accelerators of economic development. Successful clusters attract professionals, technology and investment, serve a global market and connect with other regional clusters that provide similar activities in the global value chain. The aim of this paper is the study of good practice in the development of clusters by observing the processes that lead to the accelerated development of cluster practices. Cluster organizations in Europe and Serbia are developing at different speeds and with different results. These differences are due to discrepancies in the degree of institutionalization of cluster organizations, financial assistance and the existence of supporting social infrastructure. Results of the paper are intended for policy makers and cluster management in Serbia and the region.

description: In the framework of a deep geological radioactive waste disposal in France, the hydromechanical properties of the designated host rock, the Callovo-Oxfordian claystone (COx), are investigated in laboratory tests. Experiments presented in this study are carried out to determine several coefficients required within a transversely isotropic material model. They include isotropic compression tests, pore pressure tests, and deviatoric loading tests parallel and perpendicular to the bedding plane. We emphasize the adapted experimental devices and testing procedures, necessary to detect small strains under high pressures, on a material, which is sensitive to water and has a very low permeability. In particular, we discovered a significant decrease of elastic stiffness with decreasing effective stress, which was observed to be reversible. In both isotropic and deviatoric tests, a notable anisotropic strain response was found. The Young modulus parallel to bedding was about 1.8 times higher than the one perpendicular to the bedding plane. A notably low Poisson ratio perpendicular to the bedding plane with values between 0.1 and 0.2 was evidenced. While the anisotropy of the back-calculated Biot coefficient was found to be low, a significant anisotropy of the Skempton coefficient was computed. The performed experiments provide an overdetermined set of material parameters at different stress levels. Using all determined parameters in a least square error regression scheme, seven independent elastic coefficients and their effective stress dependency are characterized. Parameters measured under isotropic loading are well represented by this set of coefficients, while the poroelastic framework with isotropic stress dependency is not sufficient to describe laboratory findings from triaxial loading.
