Singular Effect of Disorder on Electronic Transport in Strong Coupling Electron-Phonon Systems
Creators: name: Kumar, Sanjeev

Publisher: name: arXiv
Year: 2004
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We solve the disordered Holstein model in three dimensions considering the phonon variables to be classical. After mapping out the phases of the `clean' strong coupling problem, we focus on the effect of disorder at strong electron-phonon (EP) coupling. The presence of even weak disorder (i) enormously enhances the resistivity (ρ) at T=0, simultaneously suppressing the density of states at the Fermi level, (ii) suppresses the temperature dependent increase of ρ, and (iii) leads to a regime with dρ/dT <0. We locate the origin of these anomalies in the disorder induced tendency towards polaron formation, and the associated suppression in effective carrier density and mobility. These results, explicitly at `metallic' density, are of direct relevance to disordered EP materials like covalent semiconductors, the manganites, and to anomalous transport in the A-15 compounds.

 Type Species – Titanis walleri Brodkorb, 1963.
 Included Species – Only the type species.
 Distribution – Upper Pliocene to Lower Pleistocene of Florida and Texas (U.S.A.).
 Diagnosis – Size similar to that of Phorusrhacos, with a less sturdy tarsometatarsus than that of Devincenzia. The mid-trochlea, in the more distal portion, is spread out onto the sides, differentiating it from the two aforementioned species (Fig. 22C), this aspect reminding one of the Mesembriornithinae.

description: Every day, girls all over the world strive to improve their lives through education, despite significant obstacles. This thesis is an examination of the barriers to girls' secondary schooling in Nigeria and Uganda as well as a review of interventions designed to overcome these challenges. Building on a historical and theoretical background, factors preventing girls from attending and succeeding in secondary school are investigated in detail. Programs and initiatives targeted to remedy these obstacles are examined at government, international and local levels. This work aims to encourage the reader to see girls as a resource, rather than a burden. I conducted research through a review of existing literature and three interviews with education experts, two in Washington, DC, and one in Uganda. The paper concludes that, though significant barriers to girls' secondary schooling exist, they can be addressed and mitigated through the work of government, international and local actors.

description: We present the closed analytic expression of the form factors of the two-loop QED vertex amplitude for on-shell electrons of finite mass $m$ and arbitrary momentum transfer $S=-Q^2$. The calculation is carried out within the continuous $D$-dimensional regularization scheme, with a single continuous parameter $D$, the dimension of the space-time, which regularizes at the same time UltraViolet (UV) and InfraRed (IR) divergences. The results are expressed in terms of 1-dimensional harmonic polylogarithms of maximum weight 4.

Semiclassical WKB problem for the non-self-adjoint Dirac operator with a decaying potential

description: In this paper we examine the semiclassical behaviour of the scattering data of a non-self-adjoint Dirac operator with a fairly smooth but not necessarily analytic potential decaying at infinity. In particular, using ideas and methods going back to Langer and Olver, we provide the complete rigorous uniform semiclassical analysis of the scattering coefficients away (slightly) from zero, and the rigorous proof of the uniform Bohr-Sommerfeld condition for the location of the eigenvalues. Our analysis is motivated by the potential applications to the focusing cubic NLS equation, in view of the well-known fact discovered by Zakharov and Shabat that the spectral analysis of the Dirac operator is the basis of the solution of the NLS equation via inverse scattering theory. This paper complements and extends a previous work of Fujiié and the second author, which considered a more restricted problem for a strictly analytic potential.

description: This paper investigates the "experts" perspectives on the effects juvenile programming and rehabilitation has on recidivism for juvenile offenders in Polk County, in the state of Iowa. Although there is existing research on the causes of recidivism for juvenile offenders in heavily populated cities and states, there is minimal research on recidivism factors for juvenile offenders in rural areas; and there is also a small amount of research using qualitative methods from the viewpoint of the staff that work directly with juvenile offenders. Through nine qualitative interviews of three juvenile corrections rehabilitative programs, this researcher presents information on the "experts" perspectives on how juvenile programming influences juvenile recidivism, and examines how the programs themselves might influence juvenile recidivism. The information from this research will be useful for the staff that works directly with juveniles and policy makers. KEY WORDS: Juvenile offenders; Recidivism; "Experts" Perspectives on Recidivism.
title: Shh Signalling and the Specification of Neuronal Identity
Creators: name: Stamataki, Despina
Publisher: name: The Open University
Year: 2005

description: During development, many signalling factors behave as morphogens, long-range signals eliciting different cellular responses according to their concentration. In ventral regions of the spinal cord, Shh is such a signal and controls the emergence, in precise spatial order, of distinct neuronal subtypes. The Gli family of transcription factors play a central role in this process, however, how the graded aspect of Shh signalling controls differential gene expression has been unclear. To address this question we have taken a gain of function approach in chick embryos. We have designed dominant inhibitory and dominant active versions of Gli proteins that are sufficient to block all Gli mediated transcription or mimic positive Gli activity, respectively. Analysis of the effect of these constructs when ectopically expressed in chick embryonic spinal cord indicates that blocking Gli mediated transcription prevents ventral neural tube patterning and the generation of the appropriate neuronal subtypes resulting in the dorsalisation of the ventral neural tube. Conversely, Gli dependent transcription is sufficient to mediate the full range of Shh responses in the neural tube. Moreover, the 2-3 fold changes in Shh concentration, which are necessary to switch between alternative neuronal subtypes in vitro, can be mimicked in vivo by similarly small changes in the level of Gli activity. This analysis also indicated that cells integrate the level of Shh signalling over time suggesting that signal duration in addition to signal strength is an important parameter controlling dorsal-ventral patterning. Together, these data indicate that graded Shh signalling is translated into a gradient of Gli activity without substantial signal amplification and that small changes in the level of Gli activity are sufficient to orchestrate the patterning of the ventral neural tube.

description: In this paper, we have proved that if a complete conformally flat gradient shrinking Ricci soliton has linear volume growth or the scalar curvature is finitely integrable and also the reciprocal of the potential function is subharmonic, then the manifold is isometric to the Euclidean sphere. As a consequence, we have showed that a four dimensional gradient shrinking Ricci soliton satisfying some conditions is isometric to $\mathbb{S}^4$ or $\mathbb{RP}^4$ or $\mathbb{CP}^2$. We have also deduced a condition for the shrinking Ricci soliton to be compact with quadratic volume growth.

Scaling Optimization Over Uncertainty via Compilation

Year: 2025
Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: Probabilistic inference is fundamentally hard, yet many tasks require optimization on top of inference, which is even harder. We present a new optimization-via-compilation strategy to scalably solve a certain class of such problems. In particular, we introduce a new intermediate representation (IR), binary decision diagrams weighted by a novel notion of branch-and-bound semiring, that enables a scalable branch-and-bound based optimization procedure. This IR automatically factorizes problems through program structure and prunes suboptimal values via a straightforward branch-and-bound style algorithm to find optima. Additionally, the IR is naturally amenable to staged compilation, allowing the programmer to query for optima mid-compilation to inform further executions of the program. We showcase the effectiveness and flexibility of the IR by implementing two performant languages that both compile to it: dappl and pineappl. dappl is a functional language that solves maximum expected utility problems with first-class support for rewards, decision making, and conditioning. pineappl is an imperative language that performs exact probabilistic inference with support for nested marginal maximum a posteriori (MMAP) optimization via staging.

description: Grazing-Incidence X-ray fluorescence (GIXRF) analysis, which is closely related to total-reflection XRF, is a very powerful technique for the in-depth analysis of many types of technologically relevant samples, e.g. nanoparticle depositions, shallow dopant profiles, thin layered samples or even well-ordered nanostructures. However, the GIXRF based determination of the depth-dependent information about the sample is usually based on a modelling of the experimental data. This requires profound knowledge of the geometrical parameters of the setup employed, especially the incident beam profile as well as the detector aperture parameters. Together they determine the incident angle dependent so-called effective solid angle of detection which must be known in order to model any experimental data set. In this work, we demonstrate how these instrumental parameters, which are typically not known with sufficient accuracy, can be determined using dedicated experiments with a well-known calibration sample. In addition, this paves the way for a full calibration of the setup, as also information about other parameters, e.g. the incident photon flux is gained. Here, we are using a Bruker S4 T-STAR instrument for this demonstration but the principle can also be applied for other GIXRF setups.

description: For arbitrary planar convex domain, we compute the behavior of Christoffel function up to a constant factor using comparison with other simple reference domains. The lower bound is obtained by constructing an appropriate ellipse contained in the domain, while for the upper bound an appropriate parallelepiped containing the domain is constructed. As an application we obtain a new proof of existence of optimal polynomial meshes in planar convex domains.

This supplements our earlier work \cite{DCP03} in which we were successful in showing fully, gauge independence of the results in our formalism. Also in this work we treat cases in which the Stokes parameter S$_1 < 1$ so that partial polarization of the photon source is also taken into account. Agreement in shape with the Convergent Close Coupling \cite{BK03,HB98} calculation and the experiments appears to be excellent.

 1 Type of Phororhacos deautieri Kraglievich, 1931.
 Illustrations – Patterson (1941).
 Remarks – The mandibular symphysis of specimen FM-P 13383 (Figs. 25A, 25B and 25C), is smaller than that of the type specimen and the femur (FM-P 14678) (Figs. 25D, 25E and 25F) is still smaller than the corresponding bone of Patagornis marshi. However, the measurements of the type specimen lead one to believe it to have been a larger bird. This is certainly one more example of intraspecific variation in these birds, and possibly even sexual dimorphism. A phalanx of digit II (MACN-A-52-110), whereon Ameghino (1898) described Aucornis solidus, is very probably attributed to this species and the name of which naturally could have priority. However, the diagnostic value of this phalanx is very debatable, as also one can question the correct geographical and stratigraphical origin of the specimen as well. It is thus preferable in this case to consider Aucornis solidus Ameghino, 1898 as a species inquirenda.

description: VR-based learning has increased significantly in the curricula of the school-based parts of the Danish dual VET system, not least within the social and health care programmes. However, recently a project has been accomplished about developing, testing and researching VR-based learning about COPD for employees and students working in care homes. The empirical data includes interviews with seven learners. The results show that the learners are motivated for learning through VR, among other reasons, because they are active in the learning process. Furthermore, the results show that the learners achieve knowledge about a systematical treatment of COPD patients. However, they do not experience that they transfer this knowledge into altered ways of treating the patients. It is discussed why VR-based learning particularly underpins active participation and why the learners do not transfer knowledge into practice. It is concluded that VR-based learning should include systematic reflection.

description: Bound states at interfaces between superconductors and other materials are a powerful tool to characterize the nature of the involved systems, and to engineer elusive quantum excitations. In-gap excitations of conventional s-wave superconductors occur, for instance, at magnetic impurities with net magnetic moment breaking time-reversal symmetry. Here we show that interfaces between a superconductor and a quantum antiferromagnet can host robust in-gap excitations, without breaking time-reversal symmetry. We illustrate this phenomenon in a one-dimensional model system with an interface between a conventional s-wave superconductor and a one-dimensional Mott insulator described by a standard Hubbard model. This genuine many-body problem is solved exactly by employing a combination of kernel polynomial and tensor network techniques. We unveil the nature of such zero modes by showing that they can be adiabatically connected to solitonic solutions between a superconductor and a classical antiferromagnet. Our results put forward a new class of in-gap excitations between superconductors and a disordered quantum spin phase can be relevant for a wider range of heterostructures.

Homonormativity and queer resistance: LGBT activists' marriage discourses
Creators: name: Post, Shannon Michele
Publisher: name: American University
Year: 2023

description: Through interviews with LGBT and queer-identified activists in Washington, DC, this study explores the localized meanings of marriage as both a movement and personal goal in relation to activists' strategic, ideological and identity-based support or opposition. DC-based activists justified their beliefs about the movement agenda of marriage equality by engaging ideas about the local and national. Influenced by their social locations and personal identities, some activists (re)created narratives of being 'normal' and deserving the 'rights and responsibilities' of legal same-sex marriage. On the other hand, many interviewees deployed notions of privilege, oppression and the language of 'intersectionality' to resist the marriage agenda and the institution of marriage itself, yet overwhelmingly supported it as a 'practical' personal choice and ultimate movement goal. These findings contribute to the LGBT social movement literature and inform further empirical research on homonormativity and intersectionality in the activist setting.

description: The effective stress tensor of a homogeneous turbulent rotating fluid is anisotropic. This leads us to consider the most general axisymmetric four-rank ``viscosity tensor'' for a Newtonian fluid and the new terms in the turbulent effective force on large scales that arise from it, in addition to the microscopic viscous force. Some of these terms involve couplings to vorticity and others are angular momentum non conserving (in the rotating frame). Furthermore, we explore the constraints on the response function and the two-point velocity correlation due to axisymmetry. Finally, we compare our viscosity tensor with other four-rank tensors defined in current approaches to non-rotating anisotropic turbulence.

description: We have developed an approach to control the carrier density in various material under high pressure by the combination of an electric double layer transistor (EDLT) with a diamond anvil cell (DAC). In this study, this EDLT-DAC was applied to a Bi thin film, and here we report the field-effect under high pressure in the material. Our EDLT-DAC is a promising device for exploring unknown physical phenomena such as high transition-temperature superconductivity (HTS).

description: Through interviews with LGBT and queer-identified activists in Washington, DC, this study explores the localized meanings of marriage as both a movement and personal goal in relation to activists' strategic, ideological and identity-based support or opposition. DC-based activists justified their beliefs about the movement agenda of marriage equality by engaging ideas about the local and national. Influenced by their social locations and personal identities, some activists (re)created narratives of being 'normal' and deserving the 'rights and responsibilities' of legal same-sex marriage. On the other hand, many interviewees deployed notions of privilege, oppression and the language of 'intersectionality' to resist the marriage agenda and the institution of marriage itself, yet overwhelmingly supported it as a 'practical' personal choice and ultimate movement goal. These findings contribute to the LGBT social movement literature and inform further empirical research on homonormativity and intersectionality in the activist setting.

description: Results are presented for the geometry of low-energy excitations in the one-dimensional Ising spin chain with power-law interactions, in which the model parameters are chosen to yield a finite spin-glass transition temperature. Both finite-temperature and ground-state studies are carried out. For the range of sizes studied the data cannot be fitted to any of the standard spin-glass scenarios without including corrections to scaling. Incorporating such corrections we find that the fractal dimension of the surface of the excitations, is either equal to the space dimension, consistent with replica symmetry breaking, or very slightly less than it. The latter case is consistent with the droplet and "trivial-nontrivial" (TNT) pictures.

description: The main result of this thesis deals with continuous functions on metric spaces. Specifically, we show that given a continuous function f : M1 → M2 from a metric space (M1, d1) to a metric space (M2, d 2), there is a function delta : M1 x R+→R+ such that delta is continuous and, if ∀x ∈ M1 ∀epsilon > 0 ∀y ∈ M1 [d1(x, y) < delta(x, epsilon) ⇒ d2 (f (x), f (y)) < epsilon]. The above result was established by Enayat in [Ena00] using the machinery of partitions of unity. Our expository account of Enayat's paper contains a substantial body of results in general topology, including a thorough discussion of paracompact spaces and partitions of unity.

description: We study the impact of the coupling of neutrinos with a new light neutral gauge boson, $Z^\prime$, with a mass of less than 500 {\rm MeV} in FASER$ν$ experiment. Scenarios in which a light gauge boson is coupled to neutrinos are motivated within numerous contexts which are designed to explain various anomalies in particle physics and cosmology. This interaction leads to a new decay mode for charged mesons to a light lepton plus neutrino and $Z^{\prime}$, ($π^+(K^+)\to e^+ νZ^\prime$) followed by the subsequent decay of $Z^\prime$ into the pair of neutrino and anti-neutrino, ($Z^\prime \to ν\barν$). FASER$ν$, the Forward Search Experiment at the LHC, has the potential to detect collider neutrinos for the first time. In particular, the FASER$ν$ emulsion detector will provide the opportunity to detect $τ$-neutrinos and to measure their energies. Using this ability of FASER$ν$ emulsion detector, we investigate the potential of FASER$ν$ experiment and the proposed upgraded version of this experiment, FASER2$ν$, to constrain the coupling of a neutrino with the light gauge boson.

description: Based on a prior determination of the $ϕ$ selfenergy in a nuclear medium we perform a theoretical study of inclusive $ϕ$ photoproduction in nuclei, looking at the $A$ dependence of the cross sections for different $ϕ$ momenta. We find sizeable reductions in the nuclear cross sections with respect to the elementary one, using a $ϕ$ selfenergy which implies a width about six times the free one at normal nuclear density. The calculations are done to match the set up for an ongoing experiment at {\it SPring8/Osaka} which should provide valuable information on the renormalization of the $ϕ$ properties in nuclei.

description: We propose a scheme utilising a quantum interference phenomenon to switch the transport of atoms in a 1D optical lattice through a site containing an impurity atom. The impurity represents a qubit which in one spin state is transparent to the probe atoms, but in the other acts as a single atom mirror. This allows a single-shot quantum non-demolition measurement of the qubit spin.

description: Virtually all of today's Big Data systems are passive in nature, responding to queries posted by their users. Instead, we are working to shift Big Data platforms from passive to active. In our view, a Big Active Data (BAD) system should continuously and reliably capture Big Data while enabling timely and automatic delivery of relevant information to a large pool of interested users, as well as supporting retrospective analyses of historical information. While various scalable streaming query engines have been created, their active behavior is limited to a (relatively) small window of the incoming data. To this end we have created a BAD platform that combines ideas and capabilities from both Big Data and Active Data (e.g., Publish/Subscribe, Streaming Engines). It supports complex subscriptions that consider not only newly arrived items but also their relationships to past, stored data. Further, it can provide actionable notifications by enriching the subscription results with other useful data. Our platform extends an existing open-source Big Data Management System, Apache AsterixDB, with an active toolkit. The toolkit contains features to rapidly ingest semistructured data, share execution pipelines among users, manage scaled user data subscriptions, and actively monitor the state of the data to produce individualized information for each user. This paper describes the features and design of our current BAD data platform and demonstrates its ability to scale without sacrificing query capabilities or result individualization.
