description: Motivated by recent developments in magnetic materials, frustrated nanoarrays and cold atomic systems, we investigate the behaviour of dipolar spins on the frustrated two-dimensional kagome lattice. By combining the Luttinger-Tisza approach, numerical energy minimization, spin-wave analysis and parallel tempering Monte-Carlo, we study long-range ordering and finite-temperature phase transitions for a Hamiltonian containing both dipolar and nearest-neighbor interactions. For both weak and moderate dipolar interactions, the system enters a three-sublattice long-range ordered state, with each triangle having vanishing dipole and quadrupole moments; while for dominating dipolar interactions we uncover ferrimagnetic three-sublattice order. These are also the ground states for XY spins. We discuss excitations of, as well as phase transitions into, these states. We find behaviour consistent with Ising criticality for the 120-degree state, while the ferrimagnetic state appears to be associated with drifting exponents. The celebrated flat band of zero-energy excitations of the kagome nearest-neighbour Heisenberg model is lifted to finite energies but acquires only minimal dispersion as dipolar interactions are added.

Humans and Technology: a complex assemblage in daily occupations
Creators: name: Loudoun, Fiona
Publisher: name: Zenodo
Year: 2023

description: Occupational Science is defined by the "the study of the human as an occupational being" (Yerxa, 2000, p. 88), which has traditionally elevated the human as the locus of attention.  However, technologies are increasingly integrated in our daily occupations.  The complexity and intelligence of these digital technologies are shifting reliance from humans to machines.   
A transactional approach to occupation recognises that occupations are situationally-dependent phenomenon (Cutchin and Dickie, 2012).  However, a posthuman perspective extends this to acknowledge the reciprocal human – machine/technology relations.  Taylor's (2009) notion of assemblage of play provides a framework to recognise the range of actors that intra-act with each other to create the play experience.  Thus, the play or agency is not inherent in any of these individual properties, rather, it evolves and is constructed as they assemble together.
By recognising and applying an assemblage of play theory, occupational scientists can begin to recognise the increasing influence of digital technologies in our daily occupations. This workshop will examine and explore the complex assemblages that create play experiences (Taylor, 2009) recognising the range of human and non-human actors that create the play experience.  Thus, recognising the complex yet agentic role of digital technologies. 
Given the rapid acceleration of digital technologies in our daily lives and their increasing intelligence to act as independent actors; an enhanced understanding of the complex assemblage and how occupation is shared across both human and technological systems is critical.  Thus, recognising the influence of non-human matter within the play assemblage.

description: Bayesian networks (BNs) are a probabilistic graphical model widely used for representing expert knowledge and reasoning under uncertainty. Traditionally, they are based on directed acyclic graphs that capture dependencies between random variables. However, directed cycles can naturally arise when cross-dependencies between random variables exist, e.g., for modeling feedback loops. Existing methods to deal with such cross-dependencies usually rely on reductions to BNs without cycles. These approaches are fragile to generalize, since their justifications are intermingled with additional knowledge about the application context. In this paper, we present a foundational study regarding semantics for cyclic BNs that are generic and conservatively extend the cycle-free setting. First, we propose constraint-based semantics that specify requirements for full joint distributions over a BN to be consistent with the local conditional probabilities and independencies. Second, two kinds of limit semantics that formalize infinite unfolding approaches are introduced and shown to be computable by a Markov chain construction.

description: In the last decades huge theoretical effort was devoted to the development of consistent theoretical models, aiming to solve the so-called "measurement problem", to which John Bell dedicated part of his thoughts. Among these, the Dynamical Reduction Models possess the unique characteristic to be experimentally testable, thus enabling to set experimental upper bounds on the reduction rate parameter $λ$ characterizing these models. Analysing the X-ray spectrum emitted by an isolated slab of Germanium, we set the most stringent limit on the parameter $λ$ up to date.

description: We describe an experimental concept at the National Ignition Facility for specifically tailored spherical implosions to compress hydrogen to extreme densities (up to $\sim$800$\times$ solid density, electron number density n$_e$$\sim$4$\times$10$^{25}$ cm$^{-3}$ ) at moderate temperatures (T$\sim$200 eV), i.e., to conditions, which are relevant to the interiors of red dwarf stars. The dense plasma will be probed by laser-generated x-ray radiation of different photon energy to determine the plasma opacity due to collisional (free-free) absorption and Thomson scattering. The obtained results will benchmark radiation transport models, which in the case for free-free absorption show strong deviations at conditions relevant to red dwarfs. This very first experimental test of free-free opacity models at these extreme states will help to constrain where inside those celestial objects energy transport is dominated by radiation or convection. Moreover, our study will inform models for other important processes in dense plasmas, which are based on electron-ion collisions, e.g., stopping of swift ions or electron-ion temperature relaxation.

A framework for resolving the origin, nature and evolution of the diffuse interstellar band carriers?

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The carriers of the diffuse interstellar bands (DIBs) still remain an unknown commodity. Both dust and molecules have been suggested as carriers but none proposed have yet been able to explain the nature and the diversity of the DIBs. Hence, it is perhaps time to review the problem in terms of the intermediate-sized nano-particles. It is here proposed that the DIB carriers are the nm-sized and sub- nm-sized products of the UV photo-fragmentation of hydrogenated amorphous carbon grains, a-C(:H), and their heteroatom-doped variants, a-C:H:X (where X may be O, N, Mg, Si, Fe, S, Ni, P, ...). An interstellar hydrogenated amorphous carbon dust evolutionary framework is described within which a solution to the age-old DIB problem could perhaps be found.

description: We have investigated electron transport in a quasi-one dimensional (quasi-1D) electron gas as a function of the confinement potential. At a particular potential configuration, and electron concentration, the ground state of a 1D quantum wire splits into two rows to form an incipient Wigner lattice. It was found that application of a transverse magnetic field can transform a double-row electron configuration into a single-row due to magnetic enhancement of the confinement potential. The movements of the energy levels have been monitored under varying conditions of confinement potential and in-plane magnetic field. It is also shown that when the confinement is weak, electron occupation drives a reordering of the levels such that the normal ground state passes through the higher levels. The results show that the levels can be manipulated by utilising their different dependence on spatial confinement and electron concentration, thus enhancing the understanding of many body interactions in mesoscopic 1D quantum wires.

description: A total of 145,347 samples (4,322 cases) were received for the passive surveillance of melioidosis in the Serology Laboratory of Veterinary Research Institute (VRI) from the year 2012 to 2016. From the samples received, 0.63% were positive and 99.37% were negative. The objective of this study is to determine the seropositive rate and distribution of melioidosis in livestock based on cases received which comprise of sheep (37.24%, n=54,130), goat (54.01%, n=78,500), cattle (8.12%, n=11,804) and buffalo (0.63%, n=913) within the period of 5 years. A geographical mapping of seropositive cases was designed using the data from the passive surveillance and the results were visualized in a geographical mapping which provides a clear visual description on the distribution of the diseases. By 2016, positive cases were found to be concentrated in the states on the east coast of Peninsular Malaysia and Sabah. To sum up, the percentage of seropositive cases of melioidosis in 5 years has increased from 1.79% in 2012 to 12.17% in 2015 and decreased to 1.04% in 2016. From the findings, this study can provide the data needed as the indicator for the evaluation of surveillance and vaccination programmes, disease eradication planning and to monitor the distribution of seropositive cases of melioidosis in Malaysia.

description: Web search engines have marked everyone's life by transforming how one searches and accesses information. Search engines give special attention to the user interface, especially search engine result pages (SERP). The well-known ''10 blue links'' list has evolved into richer interfaces, often personalized to the search query, the user, and other aspects. More than 20 years later, the literature has not adequately portrayed this development. We present a study on the evolution of SERP interfaces during the last two decades using Google Search as a case study. We used the most searched queries by year to extract a sample of SERP from the Internet Archive. Using this dataset, we analyzed how SERP evolved in content, layout, design (e.g., color scheme, text styling, graphics), navigation, and file size. We have also analyzed the user interface design patterns associated with SERP elements. We found that SERP are becoming more diverse in terms of elements, aggregating content from different verticals and including more features that provide direct answers. This systematic analysis portrays evolution trends in search engine user interfaces and, more generally, web design. We expect this work will trigger other, more specific studies that can take advantage of our dataset.

description: ABSTRACT
Faduma Aden, Cinya Brand, Kara Milton, Donna Nielsen: INCREASING FOOD ACCESS FOR
K-5 STUDENTS OF COLOR IN DURHAM COUNTY PUBLIC SCHOOLS
(Under the direction of Anna P. Schenck and Kimberly P. Truesdale)
Food access, a social determinant of health, within the social and community context, is the stable availability of nourishing, affordable, and suitable foods. One’s exposure to a variety of foods greatly impacts their food choices and dietary quality, which can influence health
outcomes. To increase food access among students in kindergarten through fifth grade, particularly students of color, an evidence-based school food pantry (SFP) program will be implemented at five Title I elementary schools in Durham County Public Schools. School-Based
food pantries have historically been well received, with participation rates steadily increasing for over a decade. A desired outcome of this program is to increase fruit and vegetable consumption among those students that utilize the pantries. Quantitative methods will be used
to assess trends in fruit and vegetable consumption.
Spin-orbit coupling and spin relaxation in phosphorene: Intrinsic versus extrinsic effects

description: First-principles calculations of the essential spin-orbit and spin relaxation properties of phosphorene are performed. Intrinsic spin-orbit coupling induces spin mixing with the probability of b(2) approximate to 10(-4), exhibiting a large anisotropy, following the anisotropic crystalline structure of phosphorene. For realistic values of the momentum relaxation times, the intrinsic (Elliott-Yafet) spin relaxation times are hundreds of picoseconds to nanoseconds. Applying a transverse electric field ( simulating gating and substrates) generates extrinsic C-2v symmetric spin-orbit fields in phosphorene, which activate the D'yakonov-Perel' mechanism for spin relaxation. It is shown that this extrinsic spin relaxation also has a strong anisotropy and can dominate over the Elliott-Yafet one for strong enough electric fields. Phosphorene on substrates can thus exhibit an interesting interplay of both spin-relaxation mechanisms, whose individual roles could be deciphered using our results.

description: A large class of semi-Hamiltonian systems of hydrodynamic type is interpreted as the equations governing families of critical points of functions obeying the classical linear Darboux equations for conjugate nets.The distinguished role of the Euler-Poisson-Darboux equations and associated Lauricella-type functions is emphasised. In particular, it is shown that the classical g-phase Whitham equations for the KdV and NLS equations are obtained via a g-fold iterated Darboux-type transformation generated by appropriate Lauricella functions.

description: Optical near-field interactions between nanostructured matter, such as quantum dots, result in unidirectional optical excitation transfer when energy dissipation is induced. This results in versatile spatiotemporal dynamics of the optical excitation, which can be controlled by engineering the dissipation processes and exploited to realize intelligent capabilities such as solution searching and decision making. Here we experimentally demonstrate the ability to solve a decision making problem on the basis of optical excitation transfer via near-field interactions by using colloidal quantum dots of different sizes, formed on a geometry-controlled substrate. We characterize the energy transfer behavior due to multiple control light patterns and experimentally demonstrate the ability to solve the multi-armed bandit problem. Our work makes a decisive step towards the practical design of nanophotonic systems capable of efficient decision making, one of the most important intellectual attributes of the human brain.

description: Young adults increasingly rely on precarious and costly rental housing, particularly in major cities and liberalized housing markets. Amsterdam has a more regulated housing system, but increasing market-liberal logic in policy-making has led to considerable loosening of rent regulations in the last decade. One outcome has been the significant growth, and transformation, of liberalized rental housing. Drawing on city of Amsterdam survey data from 2005 to 2019, our analysis considers how recent policy and housing market shifts have generated and shaped housing inequalities for young adults. Where private rental growth was stimulated to fill the middle segment, our findings reveal that it has largely catered to affluent young adults. Households with less resources struggle to gain access, and pay more when they do. Our findings demonstrate that this variation of ‘generation rent” is not simply an outcome of market-liberal agendas, but is also shaped on a city-scale, partly through rental market restructuring.

description: A new research field is emerging in which ensembles of molecules are collectively hybridised with light in a process known as strong coupling. This hybridisation leads to the formation of new states that are part light and part matter, states known as polaritons. Here we offer an entry point into the field of molecular strong coupling. We include an overview of the essential phenomena and an introduction to the conceptual framework – considerable use is made of simple classical physics models since they are helpful in developing an intuitive understanding. Open questions are identified and discussed, as well as some of the exciting experimental and theoretical challenges that lie ahead.

description: In this paper, we study the $ϕ^4$ kink scattering from a spatially localized $\mathcal{PT}$-symmetric defect and the effect of the kink's internal mode (IM) is discussed. It is demonstrated that if a kink hits the defect from the gain side, a noticeable IM is excited, while for the kink coming from the opposite direction the mode excitation is much weaker. This asymmetry is a principal finding of the present work. Similar to the case of the sine-Gordon kink studied earlier, it is found that the $ϕ^4$ kink approaching the defect from the gain side always passes through the defect, while in the opposite case it must have sufficiently large initial velocity, otherwise it is trapped by the loss region. It is found that for the kink with IM the critical velocity is smaller, meaning that the kink bearing IM can pass more easily through the loss region. This feature, namely the "increased transparency" of the defect as regards the motion of the kink in the presence of IM is the second key finding of the present work. A two degree of freedom collective variable model offered recently by one of the co-authors is shown to be capable of reproducing both principal findings of the present work. A simpler, analytically tractable single degree of freedom collective variable method is used to calculate analytically the kink phase shift and the kink critical velocity sufficient to pass through the defect. Comparison with the numerical results suggests that the collective variable method is able to predict these parameters with a high accuracy.

Pre-melting of the planetesimals by radioactive decay of 26Al would help producing sprays of melt even at relatively low impact velocity. In this paper we study the radiative cooling of a ballistically expanding spherical cloud of chondrule droplets ejected from the impact site. We present results from a numerical radiative transfer models as well as analytic approximate solutions. We find that the temperature after the start of the expansion of the cloud remains constant for a time t_cool and then drops with time t approximately as T ~ T_0[(3/5)t/t_cool+ 2/5]^(-5/3) for t>t_cool. The time at which this temperature drop starts t_cool depends via an analytical formula on the mass of the cloud, the expansion velocity and the size of the chondrule. During the early isothermal expansion phase the density is still so high that we expect the vapor of volatile elements to saturate so that no large volatile losses are expected.

description: A comparative analysis of a description of spin dynamics in the cylindrical and Frenet-Serret coordinate systems is carried out. An equivalence of these two systems is shown. A possibility of efficient use of the cylindrical coordinate system for a calculation of spin evolution of particles and nuclei in accelerators and storage rings is caused by an immobility of its coordinate axes relative to stationary detectors.

description: Tick infestations and tick-borne diseases continue to be the leading causes of loss in livestock and revenue, particularly in developing countries, despite the prevalent use of synthetic acaricides. Research on plants as alternative sources of anti-arthropod agents has received attention from many researchers in the recent past. This interest is mainly motivated by the compelling need to move away from over-reliance on anti-arthropod synthetic chemicals, which have harmful effects on the environment and livestock. While many plants have been shown to possess anti-tick properties, such studies are in the main laboratory-based and thus their effects cannot be accounted for in the natural environments. Furthermore, knowledge on the mechanisms by which plant extracts impact ticks is sparse and not coordinated for ease of reference. The literature explored in this study was collected from indices included in the University of South Africa (UNISA) library database following keyword searches on plant extracts used as tick control methods and reviews. This article provides a consolidation of literature on the anti-tick properties of plant-based material and their prospects for being integrated with current tick control methods.
Heteroatom-doped hydrogenated amorphous carbons, a-C:H:X 'Volatile' silicon, sulphur and nitrogen depletion, blue photoluminescence, diffuse interstellar bands and ferro-magnetic carbon grain connections (Research Note)

description: Context. Hydrogenated amorphous carbons, a-C:H, can incorporate a variety of heteroatoms, which can lead to interesting effects. Aims. To investigate the doping of interstellar a-C:H grains with, principally, Si, O, N and S atoms within the astrophysical context. Methods. A search of the literature on doped a-C:H reveals a number of interesting phenomena of relevance to astrophysics. Results. X dopants in a-C:H:X materials can affect the sp3/sp2 ratio (X = Si, O and N), lead to blue photoluminescence (undoped or X = N), induce ferromagnetic-like behaviour (X = N and S) or simply be incorporated (depleted) into the structure (X = Si, O, N and S). Si and N atoms could also incorporate into fullerenes, possibly forming colour-centres that could mimic diffuse interstellar bands. Conclusions. Doped a-C:H grains could explain several dust-related conundrums, such as: 'volatile' Si in photo-dissociation regions, S and N depletion in molecular clouds, blue luminescence, some diffuse interstellar bands and ferromagnetism in carbonaceous grains.

description: Abstract
Male infertility is a prevalent concern affecting nearly half of infertile couples, often shrouded in diagnostic complexity. Metabolomics, an emerging field, holds great promise for revolutionizing the diagnosis of male infertility by examining the full spectrum of small molecule metabolites within biological samples. The review showcases how metabolomics has identified potential biomarkers in male infertility, unveiling metabolic disruptions associated with conditions like azoospermia, oligoasthenoteratozospermia, asthenozoospermia, and oligozoospermia. It distinguishes targeted and untargeted metabolomics, elucidating their roles in investigating specific pathways or conducting holistic metabolite profiling. The authors highlight the fact that bridging the gap between metabolomics and reproductive medicine is crucial to fully exploit its diagnostic and therapeutic possibilities.

description: There is a growing movement in undergraduate computer science (CS) programs to embed ethics across CS classes rather than relying solely on standalone ethics courses. One strategy is creating assignments that encourage students to reflect on ethical issues inherent to the code they write. Building off prior work that has surveyed students after doing such assignments in class, we conducted focus groups with students who reviewed a new introductory ethics-based CS assignment. In this experience report, we present a case study describing our process of designing an ethics-based assignment and proposing the assignment to students for feedback. Participants in our focus groups not only shared feedback on the assignment, but also on the integration of ethics into coding assignments in general, revealing the benefits and challenges of this work from a student perspective. We also generated novel ethics-oriented assignment concepts alongside students. Deriving from tech controversies that participants felt most affected by, we created a bank of ideas as a starting point for further curriculum development.

description: Laser-driven ion beams are defined by a number of unique features, including a large spread in energy. A stack configuration of radiochromic film (RCF) can be utilized to characterize such beams through measurements of their energy spectra. A spectroscopic procedure is reported that allows the proton energy density within each active layer of a radiochromic film (RCF) stack to be retrieved. This is based upon on a deconvolution algorithm developed through Geant4 Monte Carlo simulations to correct the contributions of energy depositions within a given film layer. Through Monte Carlo calculations, the spectrum retrieved from a simulated film stack can be retrieved and compared with a known energy spectrum, providing an examination of the efficacy of this tool. Application of the developed deconvolution procedure thus offers the potential to correctly reconstruct the incident energy spectrum of a laser-driven proton and ion beam from a stack of irradiated RCF.

description: A coupling-limited approach for the Ullmann reaction-like on-surface synthesis of a two-dimensional covalent organic network starting from a halogenated metallo-porphyrin is demonstrated. Copper-octabromo-tetraphenylporphyrin molecules can diffuse and self-assemble when adsorbed on the inert Au(111) surface. Splitting-off of bromine atoms bonded at the macrocyclic core of the porphyrin starts at room temperature after the deposition and is monitored by X-ray photoelectron spectroscopy for different annealing steps. Direct coupling between the reactive carbon sites of the molecules is, however, hindered by the molecular shape. This leads initially to an ordered non-covalently interconnected supramolecular structure. Further heating to 300°C and an additional hydrogen dissociation step is required to link the molecular macrocycles via a phenyl group and form large ordered polymeric networks. This approach leads to a close-packed covalently bonded network of overall good quality. The structures are characterized using scanning tunneling microscopy. Different kinds of lattice defects and, furthermore, the impact of polymerization on the HOMO-LUMO gap are discussed. Density functional theory calculations corroborate the interpretations and give further insight into the adsorption of the debrominated molecule on the surface and the geometry and coupling reaction of the polymeric structure.
