Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A mirror scattering vacuum fields is submitted to a quantum fluctuating radiation pressure. It also experiences a motional force, related to force fluctuations through fluctuation-dissipation relations. The resulting position fluctuations of the coupled mirror are related to the dissipative part of the mechanical admittance. We compute the time dependent position commutator, which makes apparent the difference between the low-frequency and high-frequency masses, and the anticommutator noise spectrum, which describes the ultimate sensitivity in a length measurement using mirrors.

description: For certain subrings of the mod-p cohomology ring of a compact Lie group, we give a description of the prime ideal spectrum, analogous to Quillen's description of the spectrum of the whole ring. Examples of such subrings include the Chern subring (the subring generated by Chern classes of all unitary representations), and for finite groups the subring generated by Chern classes of representations realizable over any specified field. As a corollary, we deduce that the inclusion of the Chern subring in the cohomology ring is an F-isomorphism for a compact Lie group G if and only if the following condition holds: For any homomorphism f between elementary abelian p-subgroups of G such that f(v) is always conjugate to v, there is an element g of G such that f is equal to conjugation by g.

description: The nonequilibrium description of quantum systems requires, for more than two or three particles, the use of a reduced description to be numerically tractable. Two possible approaches are based on either reduced density matrices or nonequilibrium Green's functions (NEGF). Both concepts are formulated in terms of hierarchies of coupled equations---the Bogoliubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy for the reduced density operators and the Martin-Schwinger-hierarchy (MS) for the Green's functions, respectively. In both cases, similar approximations are introduced to decouple the hierarchy, yet still many questions regarding the correspondence of both approaches remain open.

description: The causes of aggressive behavior in children with autism are poorly understood, which limits treatment options. Therefore, this study used behavioral testing and parent reports of 60 children with autism to investigate the interplay of emotion misinterpretation and hostile attribution bias in the prediction of different aggressive behaviors. Further, the additional impact of dysfunctional emotion regulation was examined. Path analyses indicated that hostile attribution bias increased verbal and covert aggression but not physical aggression and bullying. Dysfunctional emotion regulation had an additional impact on bullying, verbal aggression, and covert aggression. Emotion recognition was positively associated with hostile attribution bias. These findings provide a first insight into a complex interplay of socio-emotional variables; longitudinal studies are needed to examine causal relationships.

description: In order to compare recent experimental results with theoretical predictions we study the influence of finite conductivity of metals on the Casimir effect. The correction to the Casimir force and energy due to imperfect reflection and finite temperature are evaluated for plane metallic plates where the dielectric functions of the metals are modeled by a plasma model. The results are compared with the common approximation where conductivity and thermal corrections are evaluated separately and simply multiplied.

description: Different quantum Langevin equations obtained by coupling a particle to a field are examined. Instabilities or violations of causality affect the motion of a point charge linearly coupled to the electromagnetic field. In contrast, coupling a scatterer with a reflection cut-off to radiation pressure leads to stable and causal motions. The radiative reaction force exerted on a scatterer, and hence its quasistatic mass, depend on the field state. Explicit expressions for a particle scattering a thermal field in a two dimensional space-time are given.

description: Food access persists as a public policy concern in the United States. In the past 20 years, a variety of public and private organizations and activists have taken different approaches to address it, with varying levels of success. In the meantime, a newer actor—the dollar store—has come on the scene, proliferating widely in both urban and rural areas, alarming advocates for improved healthy food access and others. We used the business literature to describe these stores and their business models, and we reviewed scholarly literature from the public health and community development fields that is critical of them, as well as literature that views these stores as an opportunity for communities. We reviewed the efforts of localities to date to control and limit dollar stores, as well as efforts to work with them via partnerships. We offer recommendations for how planners can navigate the challenges of dollar stores to improve food access and maintain community vitality. The growth of dollar stores has added complexity to the task of improving food access in low-income communities, especially in rural and small-town settings. By staying grounded in their core competency of land use planning and regulation, and using both traditional and new tools, planners can navigate the challenges of dollar stores to achieve vibrant places with healthy, fresh food.

description: He-Ne ring laser gyroscopes are, at present, the most precise devices for absolute angular velocity measurements. Limitations to their performance come from the non--linear dynamics of the laser. Following the Lamb semi-classical theory, we find a set of critical parameters affecting the time stability of the system. We propose a method for estimating the long term drift of the laser parameters and for filtering out the laser dynamics effects from the rotation measurement. The parameter estimation procedure, based on the perturbative solutions of the laser dynamics, allow us to apply Kalman Filter theory for the estimation of the angular velocity. Results of a comprehensive Monte Carlo simulation and results of a preliminary analysis on experimental data from the ring laser prototype G-Pisa are shown and discussed.

description: Arrays of nanoparticles exploited in light scattering applications commonly only feature either a periodic or a rather random arrangement of its constituents. For the periodic case, light scattering is mostly governed by the strong spatial correlations of the arrangement, expressed by the structure factor. For the random case, structural correlations cancel each other out and light scattering is mostly governed by the scattering properties of the individual scatterer, expressed by the form factor. In contrast to these extreme cases, it is shown here that hyperuniform disorder in self-organized large-area arrays of high refractive index nanodisks enables both structure and form factor to impact the resulting scattering pattern, offering novel means to tailor light scattering. The scattering response from the authors’ nearly hyperuniform interfaces can be exploited in a large variety of applications and constitutes a novel class of advanced optical materials.

description: The composite systems can be non-uniquely decomposed into parts (subsystems). Not all decompositions (structures) of a composite system are equally physically relevant. In this paper we answer on theoretical ground why it may be so. We consider a pair of mutually un-coupled modes in the phase space representation that are subjected to the independent quantum amplitude damping channels. By investigating asymptotic dynamics of the degrees of freedom, we find that the environment is responsible for the structures non-equivalence. Only one structure is distinguished by both locality of the environmental in uence on its subsystems and a classical-like description.

description: The semileptonic decay of single-top-quark production provides a strong probe for W-prime bosons at the CERN Large Hadron Collider. We propose an explicit search strategy for pp -> W-prime -> tb -> l nu b j for use at 7 TeV and 8 TeV collider energies, and integrated luminosities ranging from 5 to 20 fb^-1. Based on detector-simulated results, we predict that a lower bound can be placed on the mass of right-handed W-prime_R with standard model-like couplings of m_{W-prime_R} > 1800 GeV at sqrt{S}=7 TeV with 5 fb^-1, and of m_{W-prime_R} > 2000 GeV at 8 TeV with 20 fb^-1. For left-handed W-prime_L bosons we find a lower bound of 1750-1800 GeV at 7 TeV and 5 fb^-1 depending on the sign of the interference with standard model single-top-quark production. We present effective coupling g^prime dependent limits for accessible masses, and stress the importance of these limits for comparison with theoretical models.

description: Fats make up a large fraction of the larval biomass in insects and are of increasing relevance for industrial purposes. The quantity of fats accumulated during the larval period can vary greatly among individuals. To selectively breed favourable fat accumulation phenotypes for commercial purpose, a genetic component underlying these differences would be required. In this study we determined the heritability of larval fat accumulation in the common housefly (Musca domestica L.). A nested paternal half-sib breeding design resulted in a total of 47 full-sib families, which produced in total 633 larvae, each phenotyped for their dry weight and fat content (absolute and relative). Adult selection was strictly standardized to reduce the variation in fat content induced by differences in development time during the immature stages: sires and dams were separated according to their pupation day and emergence day, and subsequently pooled into randomized groups. Two animal models were built to estimate the heritability of larval fat accumulation: (1) a Markov Chain Monte Carlo linear mixed model (MCMCglmm) where three sets of priors were used, and (2) one based on linear mixed model using restricted maximum likelihood (ASReml). The results showed a moderate heritability for larval absolute fat content for both MCMCglmm (between 0.30 and 0.38, depending on the set of prior used) and ASReml (0.37 ± 0.11). Slightly higher estimates were obtained for the relative fat content with both the MCMCglmm (between 0.34-0.48) and ASReml (0.47 ± 0.10). In contrast, heritability estimates for larval dry weight were low and could be obtained only with the MCMCglmm model (between 0.11-0.22). This work provides valuable insights into the quantitative genetics of larval fat characteristics, a trait of high relevance for the emerging sector producing insects for feed and food.

description: First principles density functional theory DFT+U calculations and experimental neutron diffraction structure analyses were used to determine the low-temperature crystallographic and magnetic structure of bixbyite Mn2O3. The energies of various magnetic arrangements, calculated from first principles, were fit to a cluster-expansion model using a Bayesian method that overcomes a problem of underfitting caused by the limited number of input magnetic configurations. The model was used to predict the lowest-energy magnetic states. Experimental determination of magnetic structure benefited from optimized sample synthesis, which produced crystallite sizes large enough to yield a clear splitting of peaks in the neutron powder diffraction patterns, thereby enabling magnetic-structure refinements under the correct orthorhombic symmetry. The refinements employed group theory to constrain magnetic models. Computational and experimental analyses independently converged to similar ground states, with identical antiferromagnetic ordering along a principal magnetic axis and secondary ordering along a single orthogonal axis, differing only by a phase factor in the modulation patterns. The lowest-energy magnetic states are compromise solutions to frustrated antiferromagnetic interactions between certain corner-sharing MnO6 octahedra.

description: The Unified Barangay E-Services System is a platform designed to provide online services to the community of Barangay Batasan Hills. The system was developed with the goal of improving the efficiency and accessibility of government services for the community. The development process involved creating a user-friendly website, integrating various government services, and training staff to support the platform's use. The key feature of the system is the use of augmented analytics to analyze and present data generated by the platform. This technology allows the government to make data-driven decisions about how to improve and expand the services offered through the platform. For example, it can identify which services are most frequently used by residents or identify areas where there may be a need for additional resources or support. Additionally, it can provide personalized recommendations to residents based on their usage history, improving their experience with the platform. The system received a very good interpretation from a survey of residents using it and reduced the time and effort required to access government services. The system can be a model for other communities looking to improve the delivery of government services to their residents and it is recommended that other communities implement similar platforms and incorporate augmented analytics to improve the accessibility and efficiency of government services. Furthermore, it is recommended that the Unified Barangay E-Services System continue to be updated and maintained to ensure its effectiveness.

description: We report far-IR Herschel observations obtained between 70 $μ$m and 500 $μ$m of two star-forming dusty condensations, B1-bS and B1-bN, in the B1 region of the Perseus star-forming cloud. In the Western part of the Perseus cloud, B1-bS is the only source detected in all of the 6 PACS and SPIRE photometric bands without being visible in the Spitzer map at 24 $μ$m. B1-bN is clearly detected between 100 $μ$m and 250 $μ$m. We have fitted the spectral energy distributions of these sources to derive their physical properties, and find that a simple greybody model fails to reproduce the observed SEDs. At least a two-component model, consisting of a central source surrounded by a dusty envelope is required. The properties derived from the fit, however, suggest that the central source is not a Class 0 object. We then conclude that while B1-bS and B1-bN appear to be more evolved than a pre-stellar core, the best-fit models suggest that their central objects are younger than a Class 0 source. Hence, they may be good candidates to be examples of the first hydrostatic core phase. The projected distance between B1-bS and B1-bN is a few Jeans lengths. If their physical separation is close to this value, this pair would allow the mutual interactions between two forming stars at a very early stage of their evolution to be studied.

description: A kinetic-rate equation approach in a thermally expanding medium is employed to calculate the evolution of charmonium and bottomonium distributions in heavy-ion collisions. The equilibrium properties of the quarkonia are taken from in-medium spectral functions which are schematically constrained by euclidean correlators from lattice QCD. The initial conditions for the rate equation (heavy-flavor cross sections, nuclear absorption) and the thermal evolution are constrained by data as available. After fixing two free parameters to describe charmonium data at SPS and RHIC, the predictions for LHC are discussed in light of recent data.

description: This paper aims to assess the impact of recent global crises on the system of international relations. In particular, it examines how the major shocks caused by these global crises have affected long-term trends and to what extent they have shaped the global order. The paper analyses four major global crises: the Covid-19 pandemic, the Global Financial Crisis (GFC), the Russian invasion of Ukraine and climate change. Two long-term global trends – global power shifts and globalisation – have been chosen as the axes around which the main geo-economic and geopolitical implications of these crises will be scrutinised.
 This analysis shows how each crisis has contributed to deepening trends that had already emerged from previous crises due to the persistence of unsolved issues or to the inadequacy of the efforts undertaken to address them. As a result of repeated and often mutually reinforcing global shocks, the world order is now characterised by high levels of uncertainty, fragility and unpredictability. This highlights the need for new cooperative approaches based on foresight and preparedness that aim at building more resilient political and socio-economic systems.

description: We investigated structural changes, phase diagram, and vibrational properties of hydrogen hydrate in filled-ice phase C2 by using first principles molecular dynamics simulation. It was found that the experimentally reported 'cubic' structure is unstable at low temperature and/or high pressure. The 'cubic' structure reflects the symmetry at high (room) temperature where the hydrogen bond network is disordered and the hydrogen molecules are orientationally disordered due to thermal rotation. In this sense, the 'cubic' symmetry would definitely be lowered at low temperature where the hydrogen bond network and the hydrogen molecules are expected to be ordered. At room temperature and below 30 GPa, it is the thermal effects that play an essential role in stabilizing the structure in 'cubic' symmetry. Above 60 GPa, the hydrogen bonds in the framework would be symmetrized and the hydrogen bond order-disorder transition would disappear. These results also suggest the phase behavior of other filled-ice hydrates. In the case of rare gas hydrate, there would be no guest molecues rotation-nonrotation transition since the guest molecules keep their spherical symmetry at any temperature. On the contrary methane hydrate MH-III would show complex transitions due to the lower symmetry of the guest molecule. These results would encourage further experimental studies, especially NMR spectroscopy and neutron scattering, on the phases of filled-ice hydrates at high pressures and/or low temperatures.

description: In mathematics curves are typically defined as the images of continuous real functions (parametrizations) defined on a closed interval. They can also be defined as connected one-dimensional compact subsets of points. For simple curves of finite lengths, parametrizations can be further required to be injective or even length-normalized. All of these four approaches to curves are classically equivalent. In this paper we investigate four different versions of computable curves based on these four approaches. It turns out that they are all different, and hence, we get four different classes of computable curves. More interestingly, these four classes are even point-separable in the sense that the sets of points covered by computable curves of different versions are also different. However, if we consider only computable curves of computable lengths, then all four versions of computable curves become equivalent. This shows that the definition of computable curves is robust, at least for those of computable lengths. In addition, we show that the class of computable curves of computable lengths is point-separable from the other four classes of computable curves.

description: The mechanical properties of cells are dominated by the cytoskeleton, an interconnected network of long elastic filaments. The connections between the filaments are provided by crosslinking proteins, which constitute, next to the filaments, the second important mechanical element of the network. An important aspect of cytoskeletal assemblies is their dynamic nature, which allows remodeling in response to external cues. The reversible nature of crosslink binding is an important mechanism that underlies these dynamical processes. Here, we develop a theoretical model that provides insight into how the mechanical properties of cytoskeletal networks may depend on their underlying constituting elements. We incorporate three important ingredients: nonaffine filament deformations in response to network strain; interplay between filament and crosslink mechanical properties; reversible crosslink (un)binding in response to imposed stress. With this we are able to self-consistently calculate the nonlinear modulus of the network as a function of deformation amplitude and crosslink as well as filament stiffnesses. During loading crosslink unbinding processes lead to a relaxation of stress and therefore to a reduction of the network modulus and eventually to network failure, when all crosslink are unbound. This softening due to crosslink unbinding generically competes with an inherent stiffening response, which may either be due to filament or crosslink nonlinear elasticity.

description: This paper addresses a conjecture of Kadison and Kastler that a von Neumann algebra M on a Hilbert space H should be unitarily equivalent to each sufficiently close von Neumann algebra N and, moreover, the implementing unitary can be chosen to be close to the identity operator. This is known to be true for amenable von Neumann algebras and in this paper we describe new classes of non-amenable factors for which the conjecture is valid. These are based on tensor products of the hyperfinite II_1 factor with crossed products of abelian algebras by suitably chosen discrete groups.

description: This research project investigates the potential of relinquishing control and recontextualising personal histories by surveying the notions of touch, the machine, and memory, and has been informed by my own desire and curiosities that centre on touching objects, engaging with machines, and sharing personal memories. In relinquishing control over final outcomes over the project, ‘failing’ has become an integral (cherished) part of the work and research. Three chapters explore the key instigators of the research: the generative potential of touch, the machine and memory, and a sharing of my personal histories in relation to these notions.

description: Maintaining genomic integrity is essential for all organisms and for the transfer of genetic information from one generation to another. However, DNA undergoes continuous attack from many sources, which can lead to DNA damage and therefore genomic instability. The DNA damage response refers to signalling pathways that aim to detect and repair this damage. DNA damage increases significantly during ageing, which is the biggest risk factor for neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). ALS is a fatal, rapidly progressing condition in which both the upper and lower motor neurons degenerate. There are few effective treatments for ALS, and whilst DNA damage has been increasingly described in pathophysiology, there are currently no effective ways to prevent damage or enhance DNA repair. Our group has previously shown that a novel protein chaperone, protein disulphide isomerase (PDI), is protective against multiple pathologies associated with ALS. PDI is unique because unlike other chaperones it also possesses oxidoreductase activity, which modulates redox regulation. However, whilst it has been established that PDI is protective against events associated with proteostasis in ALS, it has not been shown that PDI is protective against DNA damage. The studies from this thesis revealed that PDI is protective against DNA damage following etoposide or H2O2 treatment using an in vitro neuroblastoma cell line in which endogenous PDI was knocked down with siRNA. It was also shown that PDI is protective against apoptosis induced by DNA damage. Furthermore, PDI was found to translocate to the nucleus following DNA damage induced by etoposide, implying it has a direct rather than indirect role. Two ALS risk-causing mutants that display impaired redox activity, PDI-D292N and PDI-R300H, along with a PDI-Quad mutant lacking the redox active cystine sites, were also investigated. Whilst PDI-R300H displayed some residual protective activity against DNA damage, PDI-D292N and the Quad mutant were not protective. Hence these results indicate that the redox activity of PDI is protective against DNA damage, but this is perturbed in ALS. By defining these mechanisms further in future studies, these results can lead to design future therapeutics for ALS based on PDI that can prevent DNA damage.
The Slow Death (or Rebirth?) of Extended Star Formation in z~0.1 Green Valley Early-Type Galaxies

description: UV observations in the local universe have uncovered a population of early-type galaxies with UV flux consistent with low-level recent or ongoing star formation. We present resolved UV-optical photometry of a sample of 19 SDSS early-type galaxies at z~0.1 drawn from the sample originally selected by Salim & Rich (2010) to lie in the bluer part of the green valley in the UV-optical color-magnitude diagram as measured by GALEX. Utilizing high-resolution HST far-UV imaging provides unique insight into the distribution of UV light in these galaxies, which we call "extended star-forming early-type galaxies" (ESF-ETGs) because of extended UV emission that is indicative of recent star formation. The UV-optical color profiles of all ESF-ETGs show red centers and blue outer parts. Their outer colors require the existence of a significant underlying population of older stars in the UV-bright regions. Analysis of stacked SDSS spectra reveals weak LINER-like emission in their centers. Using a cross-matched SDSS DR7/GALEX GR6 catalog, we search for other green valley galaxies with similar properties to these ESF-ETGs and estimate that ~13% of dust-corrected green valley galaxies of similar stellar mass and UV-optical color are likely ESF-candidates, i.e., ESF-ETGs are not rare. Our results are consistent with star formation that is gradually declining in existing disks, i.e., the ESF-ETGs are evolving onto the red sequence for the first time, or with rejuvenated star formation due to accreted gas in older disks provided that the gas does not disrupt the structure of the galaxy and the resulting star formation is not too recent and bursty. ESF-ETGs may typify an important subpopulation of galaxies that can linger in the green valley for up to several Gyrs, based on their resemblance to nearby gas-rich green valley galaxies with low-level ongoing star formation.

description: In terms of the concepts of state and state transition, a new algorithm-State Transition Algorithm (STA) is proposed in order to probe into classical and intelligent optimization algorithms. On the basis of state and state transition, it becomes much simpler and easier to understand. As for continuous function optimization problems, three special operators named rotation, translation and expansion are presented. While for discrete function optimization problems, an operator called general elementary transformation is introduced. Finally, with 4 common benchmark continuous functions and a discrete problem used to test the performance of STA, the experiment shows that STA is a promising algorithm due to its good search capability.

description: Quantum steering inequalities allow to demonstrate the presence of entanglement between two parties when one of the two measurement device is not trusted. In this paper we show that quantum steering can be demonstrated for arbitrary low detection efficiency by using two-qubit non-maximally entangled states. Our result can have important applications in one-sided device-independent quantum key distribution.

description: We study the nonlinear rheology of a glass-forming binary mixture under the reversal of shear flow using molecular dynamics simulations and a schematic model of the mode-coupling theory of the glass transition (MCT). Memory effects lead to a history-dependent response, as exemplified by the vanishing of a stress-overshoot phenomenon in the stress--strain curves of the sheared liquid, and a change in the apparent elastic coefficients around states with zero stress. We investigate the various retarded contributions to the stress response at a given time schematically within MCT. The connection of this macroscopic response to single-particle motion is demonstrated using molecular-dynamics simulation.

description: For a connected graph L, let G(L) be a group with generators the vertex set of L, subject only to the relations that the ends of each edge commute. Now let H(L) be the kernel of the homomorphism from G(L) to the integers that takes each vertex to 1. M. Bestvina and N. Brady have shown that finiteness properties of H(L) are intimately related to the topology of the clique complex of L. We give a presentation for H(L), with generators the edges of L, and an infinite family of relators for each 1-cycle in L. In the case when the clique complex for L is simply-connected, we give a finite presentation for H(L), with generators the edges (or 2-cliques) of L, and two relators for each 3-clique in L.

On the Hermitian curve, its intersections with some conics and their applications to affine-variety codes and Hermitian codes

description: For any affine-variety code we show how to construct an ideal whose solutions correspond to codewords with any assigned weight. We classify completely the intersections of the Hermitian curve with lines and parabolas (in the $\mathbb{F}_{q^2}$ affine plane). Starting from both results, we are able to obtain geometric characterizations for small-weight codewords for some families of Hermitian codes over any $\mathbb{F}_{q^2}$. From the geometric characterization, we obtain explicit formulae. In particular, we determine the number of minimum-weight codewords for all Hermitian codes with $d\leq q$ and all second-weight codewords for distance-$3,4$ codes.
