description: We present a new upper bound for the orders of derivatives in the Rosenfeld-Groebner algorithm. This algorithm computes a regular decomposition of a radical differential ideal in the ring of differential polynomials over a differential field of characteristic zero with an arbitrary number of commuting derivations. This decomposition can then be used to test for membership in the given radical differential ideal. In particular, this algorithm allows us to determine whether a system of polynomial PDEs is consistent. Previously, the only known order upper bound was given by Golubitsky, Kondratieva, Moreno Maza, and Ovchinnikov for the case of a single derivation. We achieve our bound by associating to the algorithm antichain sequences whose lengths can be bounded using the results of Leon Sanchez and Ovchinnikov.

description: We have used the Submillimeter Array to image, at ~1" resolution, C2H(3-2) emission from the molecule-rich circumstellar disks orbiting the nearby, classical T Tauri star systems TW Hya and V4046 Sgr. The SMA imaging reveals that the C2H emission exhibits a ring-like morphology within each disk, the inner hole radius of the C2H ring within the V4046 Sgr disk (~70 AU) is somewhat larger than than of its counterpart within the TW Hya disk (~45 AU). We suggest that, in each case, the C2H emission likely traces irradiation of the tenuous surface layers of the outer disks by high-energy photons from the central stars.

description: The presence of losses in nonlinear photonic structures is a crucial issue for modern applications. Active parts are introduced for wave power compensation resulting in unbalanced gain and loss landscapes where localized beam propagation is, in general, dynamically unstable. Here we provide generic sufficient conditions for the relation between the gain-loss and the refractive index profiles in order to ensure efficient wave trapping and stable propagation for a wide range of beam launching conditions such as initial power, angle of incidence and position. The stability is a consequence of an underlying dynamic power balance mechanism related to a conserved quantity of wave dynamics.

description: We study the Ruderman-Kittel-Kasuya-Yosida effective exchange interaction between magnetic impurities embedded on the edges of transition-metal dichalcogenide flakes, using a three-orbital tight-binding model. Electronic states lying midgap of the bulk structure have strong one-dimensional (1D) character, localized on the edges of the crystallite. This results in exchange interactions with $1/r$ (or slower) decay with distance $r$, similar to other 1D systems. Most interestingly, however, the strong spin-orbit interaction in these materials results in sizable non-collinear Dzyaloshinskii-Moriya interactions between impurities, comparable in size to the usual Ising and in-plane components. Varying the relevant Fermi energy by doping or gating may allow one to modulate the effective interactions, controlling the possible helical ground state configurations of multiple impurities.

description: In the generic phase diagram of heavy fermion systems, tuning an external parameter such as hydrostatic or chemical pressure modifies the superconducting transition temperature. The superconducting phase forms a dome in the temperature-tuning parameter phase diagram, which is associated with a maximum of the superconducting pairing interaction. Proximity to antiferromagnetism suggests a relation between the disappearance of antiferromagnetic order and superconductivity. We combine muon spin rotation, neutron scattering, and x-ray absorption spectroscopy techniques to gain access to the magnetic and electronic structure of CeCo(In$_{1-x}$Cd$_x$)$_5$ at different time scales. Different magnetic structures are obtained that indicate a magnetic order of itinerant character, coexisting with bulk superconductivity. The suppression of the antiferromagnetic order appears to be driven by a modification of the bandwidth/carrier concentration, implying that the electronic structure and consequently the interplay of superconductivity and magnetism is strongly affected by hydrostatic and chemical pressure.

description: In statistical process control, the total number of nonconformities per unit of a process is monitored by using the c chart. In this study, the run length performance of the synthetic c chart with known process parameter (denoted as the KP-Syn-c chart) and the synthetic c chart with estimated process parameter (denoted as the EP-Syn-c chart) are evaluated in terms of the median run length (MRL). The results show that the sensitivity of the MRL-based EP-Syn-c chart is dependent on the number of preliminary samples used in the Phase-I analysis. Furthermore, percentiles of the run length distribution are used to provide a better understanding for the run length performance of the EP-Syn-c chart. The numerical analysis shows that the required minimum number of preliminary samples can be very large for the MRL-based EP-Syn-c chart to perform similar as the KP-Syn-c chart. An optimization procedure is suggested to compute the design parameters of the EP-Syn-c chart by minimizing the out-of-control MRL. Furthermore, the optimal design procedure of the EP-Syn-c chart is also provided through minimizing the out-of-control expected MRL for the unknown process shift size. An example is provided to illustrate the design and implementation of the MRL-based EP-Syn-c chart.
Coherent Detection of Turbo-Coded OFDM Signals Transmitted through Frequency Selective Rayleigh Fading Channels with Receiver Diversity and Increased Throughput
Creators: name: Vasudevan, K.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this work, we discuss techniques for coherently detecting turbo coded orthogonal frequency division multiplexed (OFDM) signals, transmitted through frequency selective Rayleigh (the magnitude of each channel tap is Rayleigh distributed) fading channels having a uniform power delay profile. The channel output is further distorted by a carrier frequency and phase offset, besides additive white Gaussian noise (AWGN). A new frame structure for OFDM, consisting of a known preamble, cyclic prefix, data and known postamble is proposed, which has a higher throughput compared to the earlier work. A robust turbo decoder is proposed, which functions effectively over a wide range of signal-to-noise ratio (SNR). The key contribution to the good performance of the practical coherent receiver is due to the use of a long preamble (512 QPSK symbols), which is perhaps not specified in any of the current wireless communication standards. We have also shown from computer simulations that, it is possible to obtain even better BER performance, using a better code. A simple and approximate Cramer-Rao bound on the variance of the frequency offset estimation error for coherent detection, is derived. The proposed algorithms are well suited for implementation on a DSP-platform.

Cholera Transmission in Bangladesh: Social Networks and Neighborhoods

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Transmission of infectious pathogens across networks is well-documented, yet remains primarily focused on diseases spread by sexual contact. Such analytical tools, however, may also facilitate understanding of how other types of health outcomes are related to physical and social contacts. This research examines the relationship between cholera incidence and the social network that links households in rural Bangladesh. Using twenty-one years of longitudinal demographic and health data, clustering of similar disease rates in the network was measured and compared to spatial autocorrelation of cholera at the neighborhood level. Results indicate that rates are significantly concentrated amongst households within the same local environment, and that social clustering is only evident during certain years examined. These outcomes suggest that intervention efforts should place priority on identifying local-level environmental factors, but also consider the potential of networks as they assist transmission, as well as their role in interactions within a defined neighborhood.

I briefly outline the emergence of this relatively new subfield of astronomy over the past two decades, and offer a few examples illustrating how the study of NYMGs and their members enables unique investigations of pre-main sequence stellar evolution, evolved protoplanetary disks, and young exoplanets.

Effects of Landau-Lifshitz-Gilbert damping on domain growth

description: Domain patterns are simulated by the Landau-Lifshitz-Gilbert (LLG) equation with an easy-axis anisotropy. If the Gilbert damping is removed from the LLG equation, it merely describes the precession of magnetization with a ferromagnetic interaction. However, even without the damping, domains that look similar to those of scalar fields are formed, and they grow with time. It is demonstrated that the damping has no significant effects on domain growth laws and large-scale domain structure. In contrast, small-scale domain structure is affected by the damping. The difference in small-scale structure arises from energy dissipation due to the damping.

description: Magnetocaloric effect in a double-tetrahedral chain, in which nodal lattice sites occupied by the localized Ising spins regularly alternate with three equivalent lattice sites available for mobile electrons, is exactly investigated by considering the one-third electron filling and the ferromagnetic Ising exchange interaction between the mobile electrons and their nearest Ising neighbours. The entropy and the magnetic Gruneisen parameter, which closely relate to the magnetocaloric effect, are exactly calculated in order to investigate the relation between the ground-state degeneracy and the cooling efficiency of the hybrid spin-electron system during the adiabatic demagnetization.

description: Interaction of axisymmetrically-polarized (radially or azimuthally-polarized), relativistically intense laser pulses (ALP) with under-dense plasma is shown experimentally to be different from the interaction of conventional Gaussian pulses. The difference is clearly observed in distinct spectra of scattered laser light as well as in appearance of a strong side emission of second harmonic in the vicinity of focus spot. According 3D particle-in-cell simulations, this is a result of instability in the propagation of ALP in under-dense plasma. Laser wakefield acceleration of electrons by ALP, therefore, is less efficient than that by Gaussian laser pulses but ALP may be interesting for efficient electron self-injection.

Examining the Impacts of the Pandemic on Vulnerable Population Groups

Publisher: name: University of Illinois at Chicago

description: The COVID-19 pandemic has impacted many lives in one way or another and is arguably one of modern history's most disruptive and unprecedented events. As many employers shifted from the typical workplace to a remote work environment for their employees to limit the spread of the pervasive virus under the direction of healthcare and government officials, many others were forced to close their doors altogether, drastically changing the structure of the workforce. While the shift to work-from-home is one of the most noticeable impacts of the pandemic, the effects on employment are widespread, especially for the most vulnerable. We examine whether the COVID-19 pandemic has disproportionality impacted vulnerable populations exacerbating preexisting inequities. More specifically, we examine work-from-home for individuals with disabilities, the gender employment gap, and the impacts on employment for low-income individuals. A nationwide comprehensive and multi-wave survey, i.e., the COVID Future survey, were collected, providing information about how the COVID-19 pandemic impacted the lives of individuals. We find that vulnerable populations, namely individuals with disabilities, women, and low-income earners, are disproportionately affected, further extending disparities.

title: The Linguistic Cycle in Ancient Egyptian Verbal Constructions
Creators: name: McLaughlin, Rachael
Publisher: name: University of Liverpool Repository
Year: 2023

description: The linguistic cycle pattern, involving the repeating alternation between analyticity and syntheticity, is clearly visible in many constructions across the development of the ancient Egyptian language between Old Egyptian and Coptic. This thesis aims to provide a detailed, evidence-based account of the linguistic cycle pattern in the diachronic developments of Egyptian verbal constructions, and to further understanding of how and why this pattern was formed. The first chapter of this thesis introduces the key themes, research questions and methodology featured throughout the thesis, including three illustrative crosslinguistic examples of the linguistic cycle and a discussion of motivations for the formation of this pattern. The second chapter observes and analyses how the linguistic cycle was formed in the development of each individual construction, establishing the linguistic processes involved in analyticisation and syntheticisation in each case. The following three chapters provide a comparison between the verbal constructions analysed in chapter 2, determining the nature of the linguistic cycle in Egyptian verbal constructions through similarities between constructions, as well as establishing differences. It is determined that analyticisation occurred through the addition of new elements to constructions, primarily through the process of auxiliarification, while syntheticisation involved the reduction of a construction, primarily through the processes of erosion and coalescence. It is also proven that the linguistic cycle in Egyptian verbal constructions was not truly cyclical, and that this pattern occurred over various different time scales in different constructions. It is consequently argued that, in the context of the linguistic cycle, constructions must be examined individually, rather than an entire language or language phase being categorised. At various stages throughout these chapters, the findings from Egyptian verbal constructions are compared with the three known examples of the linguistic cycle from different languages given in chapter 1, establishing various similarities. This adds to evidence for the currently unanswered question of the universality of the linguistic cycle pattern. It also demonstrates how the Egyptian language, which as the world’s longest attested language offers a unique opportunity to examine linguistic patterns over a more extended time period than any other language, can reveal more about the linguistic cycle as a crosslinguistic pattern than its current application in linguistic works. The final chapter summarises the findings of this thesis, and presents conclusions to its primary research questions.
Amplification effects in optomechanics via weak measurement

description: We revisit the scheme of single-photon weak-coupling optomechanics using post-selection, proposed by Pepper, Ghobadi, Jeffrey, Simon and Bouwmeester [Phys. Rev. Lett. 109, 023601 (2012)], by analyzing the exact solution of the dynamical evolution. Positive and negative amplification effects of the displacement of the mirror's position can be generated when the Kerr phase is considered. This effect occurs when the post-selected state of the photon is orthogonal to the initial state, which can not be explained by the usual weak measurement results. The amplification effect can be further modulated by a phase shifter, and the maximal displacement state can appear within a short evolution time.

description: We prove that every 3-connected planar graph on $n$ vertices contains an induced path on $Ω(\log n)$ vertices, which is best possible and improves the best known lower bound by a multiplicative factor of $\log \log n$. We deduce that any planar graph (or more generally, any graph embeddable on a fixed surface) with a path on $n$ vertices, also contains an induced path on $Ω(\sqrt{\log n})$ vertices. We conjecture that for any $k$, there is a contant $c(k)$ such that any $k$-degenerate graph with a path on $n$ vertices also contains an induced path on $Ω((\log n)^{c(k)})$ vertices. We provide examples showing that this order of magnitude would be best possible (already for chordal graphs), and prove the conjecture in the case of interval graphs.

Recovering health care in post-Katrina New Orleans
Creators: name: Davis, Molly Mclean
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: This thesis describes the Louisiana health care system. The literature review is a case study of the New Orleans health care sector, previous to and after Hurricane Katrina. The review examines criticism of the system, particularly criticisms of the public hospital system, the Medicaid disproportionate share hospital reimbursement fund, the low rate of insurance coverage among Louisiana residents and the barriers to health care in New Orleans’ indigent population. The main body of the thesis is a series of journalistic articles. The first article is an overview of the system and the proposed “dollar follow the patient” reform. The second two articles are narratives, the first based on a provider and the second on a patient. The conclusion supports reform of Louisiana’s health care funding and payment system, in order to bring health care coverage closer to a universal level, alleviate the burden of an under-funded hospital system and create a healthier population in the long term.

Subjects: school dropout; adolescent pregnancy; Venezuelan-Colombian border

description: The objective was to compare school dropout of adolescent mothers in the Venezuelan-Colombian border of Táchira State and the North of Santander, considering as factors the age at the moment of abandoning the studies, the educational level and the school performance before the desertion for the determination of requirements conducive to social development. The quantitative methodology was used with two samples: 235 adolescent mothers in Táchira and 406 in North of Santander. The results indicate for both contextsa statistically significant association between school dropout before pregnancy and age at school dropout, educational level and independence with previous academic performance. It is noted that in the abandonment of studies, influences the sociological age by an advance of roles unrelated to chronological age. It is concluded that a quality education that involves professional preparation and stops adolescent pregnancy through curricular planning according to childhood and youth that motivates intrinsically and extrinsically towards a better future is required in the studied reality.

description: Current multispectral imagers suffer from low photon efficiency and limited spectrum range. These limitations are partially due to the technological limitations from array sensors (CCD or CMOS), and also caused by separative measurement of the entries/slices of a spatial-spectral data cube. Besides, they are mostly expensive and bulky. To address above issues, this paper proposes to image the 3D multispectral data with a single bucket detector in a multiplexing way. Under the single pixel imaging scheme, we project spatial-spectral modulated illumination onto the target scene to encode the scene's 3D information into a 1D measurement sequence. Conventional spatial modulation is used to resolve the scene's spatial information. To avoid increasing requisite acquisition time for 2D to 3D extension of the latent data, we conduct spectral modulation in a frequency-division multiplexing manner in the speed gap between slow spatial light modulation and fast detector response. Then the sequential reconstruction falls into a simple Fourier decomposition and standard compressive sensing problem. A proof-of-concept setup is built to capture the multispectral data (64 pixels $\times$ 64 pixels $\times$ 10 wavelength bands) in the visible wavelength range (450nm-650nm) with acquisition time being 1 minute. The imaging scheme is of high flexibility for different spectrum ranges and resolutions. It holds great potentials for various low light and airborne applications, and can be easily manufactured production-volume portable multispectral imagers.

description: Decision making is critical in our daily lives and for society in general and is finding evermore practical applications in information and communication technologies. Herein, we demonstrate experimentally that single photons can be used to make decisions in uncertain, dynamically changing environments. Using a nitrogen-vacancy in a nanodiamond as a single-photon source, we demonstrate the decision-making capability by solving the multi-armed bandit problem. This capability is directly and immediately associated with single-photon detection in the proposed architecture, leading to adequate and adaptive autonomous decision making. This study makes it possible to create systems that benefit from the quantum nature of light to perform practical and vital intelligent functions.

description: A direct correspondence of quantum mechanics as a minisuperspace model for a self-interacting scalar quantum-field theory is established by computing, in several models, the infrared contributions to 1-loop effective potentials of Coleman--Weinberg type. A minisuperspace approximation rather than truncation is thereby obtained. By this approximation, the spatial averaging scale of minisuperspace models is identified with an infrared scale (but not a regulator or cut-off) delimiting the modes included in the minisuperspace model. Some versions of the models studied here have discrete space or modifications of the Hamiltonian expected from proposals of loop quantum gravity. They shed light on the question of how minisuperspace models of quantum cosmology can capture features of full quantum gravity. While it is shown that modifications of the Hamiltonian can well be described by minisuperspace truncations, some related phenomena such as signature change, confirmed and clarified here for modified scalar field theories, require at least a perturbative treatment of inhomogeneity beyond a strict minisuperspace model. The new methods suggest a systematic extension of minisuperspace models by a canonical effective formulation of perturbative inhomogeneity.

description: Student-athletes often know how to recognize leadership, but struggle to master techniques to best exemplify leadership characteristics. In 2003, sport psychologist Jeff Janssen partnered with the University of North Carolina at Chapel Hill (UNC) Athletics Department to create a learning environment fostering leadership within the unique special population of student-athletes. The creation of the Carolina Leadership Academy (CLA), comprised of a three-tiered formal leadership development curriculum, set UNC apart as a leader in higher education and intercollegiate athletics leadership development programs by helping student-athletes, administrators and coaches understand and foster leadership best practices. This formal leadership curriculum begins with the Carolina CREED program completed by all first year student-athletes at UNC. The intent of this mandatory foundational program is to introduce freshmen to the importance of personal leadership development. Quantitative and qualitative analysis were used to analyze research questions and examine the relationship between gender and student-athletes' perceived effectiveness of the CREED program curriculum components. A survey including twelve five-point Likert-scale and four open-ended questions was electronically transmitted to 211 student-athletes who completed the CREED program in the Spring 2008 semester. Other large universities look to UNC as a model for future leadership programming options. Therefore, these research findings from the Carolina CREED program curriculum will enable other intercollegiate athletic departments nationwide to improve student-athlete first-year leadership development programming.

description: Zero-knowledge proofs are mathematical cryptographic methods to demonstrate the validity of a claim while providing no further information beyond the claim itself. The possibility of using such proofs to process classified and other sensitive physical data has attracted attention, especially in the field of nuclear arms control. Here we demonstrate a non-electronic fast neutron differential radiography technique using superheated emulsion detectors that can confirm that two objects are identical without revealing their geometry or composition. Such a technique could form the basis of a verification system that could confirm the authenticity of nuclear weapons without sharing any secret design information. More broadly, by demonstrating a physical zero-knowledge proof that can compare physical properties of objects, this experiment opens the door to developing other such secure proof-systems for other applications.

'It’s all their Fault’. Immigrants as Scapegoats and a Mirror Revealing Social Contradictions
Creators: name: Cecchi, Sergio
Publisher: name: QuiEdit
Year: 2019
Subjects: economic inequality, immigration, scapegoat

description: This article analyses the role as scapegoat and the ‘mirroring’ function performed by immigrants in societies where levels of economic inequality are increasing, and welfare structures are being constantly contracted. The central argument of this article is that, in a situation of prolonged economic crisis, political elites can blame certain minority groups for causing difficulties that really arise from macrosocial factors.

In the first section, the article examines the creation in and by the media of the image of immigrants as ‘the enemy within’, demonstrating the arbitrariness of this categorisation and how it acts as a catalyst for the discontent felt by native populations, in particular the Italian people. The social construction of immigrants as potential perils to law and order and as unfair competitors in the job market and in applications for welfare resources (which does not find confirmation in scientific research) also performs the function of legitimising the political elites in a time of enduring economic crisis and changes in the capitalist economic model. The second section illustrates the dynamics, causes and consequences of the growth of economic inequality in economies around the world, with wages and pensions falling. States find themselves in great difficulty trying to counteract these processes of impoverishment in the population with social welfare measures. The third and final section looks at the ‘mirroring’ function performed by immigrants. They act as a convenient catalyst for the anger of the native populations, in part because the conditions of financial uncertainty and social marginalisation in which immigrants so often live are also beginning to seem like the probable future for the natives. Therefore, immigrants show us an image of poverty and uncertainty which seemed to have been definitely defeated through the development of welfare systems but is returning.

description: We report observations of a deep near-ultraviolet (NUV) survey of the Kepler field made in 2012 with the Galaxy Evolution Explorer (GALEX) Complete All-Sky UV Survey Extension (CAUSE). The GALEX-CAUSE Kepler survey (GCK) covers 104 square degrees of the Kepler field and reaches limiting magnitude NUV=22.6 at 3σ. Analysis of the GCK survey has yielded a catalog of 669,928 NUV sources, of which 475,164 are cross-matched with stars in the Kepler Input Catalog (KIC). Approximately 327 of 451 confirmed exoplanet host stars and 2614 of 4696 candidate exoplanet host stars identified by Kepler have NUV photometry in the GCK survey. The GCK catalog should enable the identification and characterization of UV-excess stars in the Kepler field (young solar-type and low-mass stars, chromospherically active binaries, white dwarfs, horizontal branch stars, etc.), and elucidation of various astrophysics problems related to the stars and planetary systems in the Kepler field.

Perspective of the Actor-Network Approach on Studies about Water

Subjects: hydrosocial networks; actants; hybrid flow

description: Current struggles related to water access and control require modifying how heterogeneous connections that water establishes with diverse technical, social and natural processes during its circulation are studied. Actor-network theory is a useful approach to this kind of analysis since it allows the researcher to observe the reality as a network of relationships among human and non-human actors. The use of this approach in studies about water is still relatively scarce, and its application may seem a bit difficult and abstract to those who are starting to adopt it. The aim of this work is to provide a methodological and conceptual background to researchers and students on the use of the actor-network theory in studies about water. The information extracted from the analysis of 13 studies included methodological aspects and descriptions of socio-technical networks deployed through urban or rural infrastructure, regulatory frameworks, and contractual arrangements. In conclusion, the studies allowed the visualization of the main interactions of analysis employed to follow actants and to examine their inscriptions in the hydrosocial networks.

description: We present high-energy x-ray diffraction data under applied pressures up to p = 29 GPa, neutron diffraction measurements up to p = 1.1 GPa, and electrical resistance measurements up to p = 5.9 GPa, on SrCo2As2. Our x-ray diffraction data demonstrate that there is a first-order transition between the tetragonal (T) and collapsed-tetragonal (cT) phases, with an onset above approximately 6 GPa at T = 7 K. The pressure for the onset of the cT phase and the range of coexistence between the T and cT phases appears to be nearly temperature independent. The compressibility along the a-axis is the same for the T and cT phases whereas, along the c-axis, the cT phase is significantly stiffer, which may be due to the formation of an As-As bond in the cT phase. Our resistivity measurements found no evidence of superconductivity in SrCo2As2 for p <= 5.9 GPa and T >= 1.8 K. The resistivity data also show signatures consistent with a pressure-induced phase transition for p >= 5.5 GPa. Single-crystal neutron diffraction measurements performed up to 1.1 GPa in the T phase found no evidence of stripe-type or A-type antiferromagnetic ordering down to 10 K. Spin-polarized total-energy calculations demonstrate that the cT phase is the stable phase at high pressure with a c/a ratio of 2.54. Furthermore, these calculations indicate that the cT phase of SrCo2As2 should manifest either A-type antiferromagnetic or ferromagnetic order.

description: Weak measurement [1,19] combined with quantum delayed-choice experiment that use quantum beam splitter instead of the beam splitter give rise to a surprising amplification effect, i.e., counterintuitive negative amplification effect. We show that this effect is caused by the wave and particle behaviours of the system to be and can't be explained by a semiclassical wave theory, due to the entanglement of the system and the ancilla in quantum beam splitter. The amplification mechanism about wave-particle duality in quantum mechanics lead us to a scheme for implementation of weak measurement in optomechanical system.
