Majorization entropic uncertainty relations for quantum operations
Creators: name: Rastegin, Alexey E.

Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Majorization uncertainty relations are derived for arbitrary quantum operations acting on a finite-dimensional space. The basic idea is to consider submatrices of block matrices comprised of the corresponding Kraus operators. This is an extension of the previous formulation, which deals with submatrices of a unitary matrix relating orthogonal bases in which measurements are performed. Two classes of majorization relations are considered: one related to tensor product of probability vectors and another one related to their direct sum. We explicitly discuss an example of a pair of one-qubit operations, each of them represented by two Kraus operators. In the particular case of quantum maps describing orthogonal measurements the presented formulation reduces to earlier results derived for measurements in orthogonal bases. The presented approach allows us also to bound the entropy characterizing results of a single generalized measurement.

description: We investigated structural, magnetic and electrical properties of sputter deposited Mn-Fe-Ga compounds. The crystallinity of the Mn-Fe-Ga thin films was confirmed using x-ray diffraction. X-ray reflection and atomic force microscopy measurements were utilized to investigate the surface properties, roughness, thickness and density of the deposited Mn-Fe-Ga. Depending on the stoichiometry, as well as the used substrates (SrTiO3 (001) and MgO (001)) or buffer layer (TiN) the Mn-Fe-Ga crystallizes in the cubic or the tetragonally distorted phase. Anomalous Hall effect and alternating gradient magnetometry measurements confirmed strong perpendicular magnetocrystalline anisotropy. Low saturation magnetization and hard magnetic behavior was reached by tuning the composition. Temperature dependent anomalous Hall effect measurements in a closed cycle He-cryostat showed a slight increase in coercivity with decreasing temperature (300K to 2K). TiN buffered Mn2.7Fe0.3Ga revealed sharper switching of the magnetization compared to the unbuffered layers.

The Role of Gap Junctional Intercellular Communication in Tumor Promotion and Development of an Improved In-vitro Assay for Assessment of Carcinogenic Risk Due to Inhibition of Communication
Creators: name: Taylor, Hope C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: An apparent linkage between gap junctional intercellular communication (GJIC) and promotion of neoplastic growth is frequently mentioned in the literature of carcinogenesis and used as the rationale for several in-vitro assays for tumor promoting compounds. The biological theory behind such an association has not been adequately developed, however, limiting the ability of researchers to optimally design and interpret in-vitro experiments measuring GJIC. In the present work, such theory is first descriptively developed, and then applied to an evaluation of the utility of currently used assays for assessing tumor promoting ability of test compounds. Results of these experiments and theoretical considerations are used to explicitly state the epistemic basis and strength of claims for a causative relationship between decreased gap junctional communication and cancer. Next, a type of experiment is proposed which meets the stated conditions under which a result of diminished GJIC is strongly indicative of increased risk of cancer via promotional effects. Some observations from preliminary attempts to perform this type of experiment with two heterologous cell systems are presented. Based on the earlier discussion of promotional theory, and the extensive literature on altered focal growth in rat liver, a detailed biological description of the promotional phase of rat liver carcinogenesis is proposed, including an explanation of the effects of phenobarbital on this phase. This description can be formalized in a model describing the proliferation of initiated cells as a consequence of an induced shift in phenotypic expression of initiated cells to a relatively non-communicating form with a lower rate of programmed cell death. Literature data for altered cell proliferation in rat liver are used to constrain the cell cycling and kinetic parameters used in the model and to begin to establish a quantitative relationship between downregulation of GJIC and rat liver carcinogenesis.

An Analysis of Adaptive Finite Element Methods for Simulating Two-Dimensional Contaminant Transport in Groundwater Systems
Creators: name: Williams, Glenn A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: A multi-level, adaptive finite element model is developed to simulate groundwater contaminant transport in two spatial dimensions. The results show that this method is effective in capturing sharp fronts, and is capable of accurately approximating solutions to large-scale problems. A substantial savings in computational cost is achieved as compared to the single-domain, non-adaptive finite element model, with resultant error being approximately the same. A potential savings in computer storage requirements over the non-adaptive method is also available.

Particle on a Torus Knot: Constrained Dynamics and Semi-Classical Quantization in a Magnetic Field

description: Kinematics and dynamics of a particle moving on a torus knot poses an interesting problem as a constrained system. In the first part of the paper we have derived the modified symplectic structure or Dirac brackets of the above model in Dirac's Hamiltonian framework, both in toroidal and Cartesian coordinate systems. This algebra has been used to study the dynamics, in particular small fluctuations in motion around a specific torus. The spatial symmetries of the system have also been studied. In the second part of the paper we have considered the quantum theory of a charge moving in a torus knot in the presence of a uniform magnetic field along the axis of the torus in a semiclassical quantization framework. We exploit the Einstein - Brillouin - Keller (EBK) scheme of quantization that is appropriate for multidimensional systems. Embedding of the knot on a specific torus is inherently two dimensional that gives rise to two quantization conditions. This shows that although the system, after imposing the knot condition reduces to a one dimensional system, even then it has manifest non-planar features which shows up again in the study of fractional angular momentum. Finally we compare the results obtained from EBK (multi-dimensional) and Bohr-Sommerfeld (single dimensional) schemes. The energy levels and fractional spin depend on the torus knot parameters that specifies its non-planar features. Interestingly, we show that there can be non-planar corrections to the planar anyon-like fractional spin.

Effect of Ozonation on Biodegradation Kinetics and Adsorption of Natural Organic Matter
Creators: name: Parameswar, Chitra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: Ozonation is an alternative to chlorination in primary disinfection, but it is a process with the following drawbacks: 1) it increases the biodegradability of natural organic matter (NOM), and thus increases the potential for bacterial regrowth in the distribution system and 2) potentially harmful disinfection by-products (DBFs) are formed which include aldehydes, ketones, peroxides and organic acids; which are themselves biodegradable. This study was aimed at formulating an experimental protocol for bench-scale studies to obtain in formation on NOM removal through biodegradation and adsorption. NOM was measured by dissolved organic carbon (DOC). Three ratios of ozone (0.5:1, 1:1, and 2:1 as O3/DOC by weight) were used to determine the effect on NOM biodegradability and adsorption. The biokinetic data was used to determine the optimum empty-bed-contact time (EBCT) and loading rates for NOM stabilization in flow through biofilters. Equilibrium adsorption isotherms with powdered activated carbon (PAC) were conducted at all O3/DOC ratios before and after biostabilization. The effect of increasing ozone dose was to increase biodegradability, a result well-supported by previous studies. At 2:1 O3/DOC, almost 35% of the DOC was removed. Biomass on the anthracite was quantified by means of a phospholipid technique. Biokinetics were normalized by biomass concentration. Removal rate constants at all three O3/DOC ratios were found to be the same. Removal rate constants were used to predict DOC removal in anthracite and GAC continuous flow reactors. The rate constant was a good predictor for the anthracite media but underpredicted for the GAC media. Adsorbability was found to decrease with O3/DOC ratio up to 2:1. At the 2:1 ratio adsorbability increased. This was thought to be due to competing effects of increasing hydrophilicity and decreasing molecular size that result with ozonation. After biostabilization, the non-biodegradable DOC was found to have the same adsorptive behavior for all O3/DOC ratios which were different from the no ozone test case. Almost all NOM both before and after biostabilization was removable by adsorption.

Model and Rule for Optimal Water Rationing
Creators: name: Brandt, Peiffer A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: This report describes a process for deriving a water rationing policy. The process consists of developing a mathematical programming model of the system, and using logit analysis to derive a set of rationing rules based on results from the optimization model. The mathematical programming model was first developed with the objective to minimize rationing. Modifications to the model included changing the objective from minimizing rationing to minimizing a unitless value analogous to cost, adding a cost term for drawdown, changing the rationing penalty so it occurs after the reservoir has been drawn down, and adding two stages of rationing. Logit analysis was used to be determine a set of equations for predicting the need for rationing, which was done with reasonable accuracy. The equations are best suited to serve as a tool to alert decision makers that rationing may be necessary. The approach used in this study has potential to be useful in other applications.

description: In a model where Majorana neutrinos heavier than the electroweak scale couple to Standard Model Higgs bosons and leptons, we compute systematically thermal corrections to the direct and indirect CP asymmetries in the Majorana neutrino decays. These are key ingredients entering the equations that describe the thermodynamic evolution of the induced lepton-number asymmetry eventually leading to the baryon asymmetry in the universe. We compute the thermal corrections in an effective field theory framework that assumes the temperature smaller than the masses of the Majorana neutrinos and larger than the electroweak scale, and we provide the leading corrections in an expansion of the temperature over the mass. In this work, we consider the case of two Majorana neutrinos with nearly degenerate masses.

Prediction and Validation of Capture Efficiencies in a Simple Push-Pull Ventilation System
Creators: name: Prat-Fourcade, Philippe
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: A push-pull ventilation system was installed in a wind tunnel where uniform perpendicular crossdraft velocities were generated. The push-pull ventilation system comprised a 4 inch diameter hood aligned with a 0.25 inch diameter jet. To determine capture efficiency of this system, tracer gas was injected in the jet and measured downstream in the hood duct. The hood exhaust was fixed at 500 cfm. For varying hood-jet distances, Z, and different crossdraft velocities, capture efficiencies were measured and plotted versus Z. A computer model was tested with these results: the predicted capture efficiencies were, on average, 33 % lower than the measured ones. This finding is consistent with other works on deflected jets and several explanations were suggested. An empirical model to predict capture efficiency within the range of study was proposed.

description: Using fully automated chemical compound extraction processes, Patentscope, SureChEMBL and Google Patents identify
 chemical compounds in patents periodically delivered to PubChem. In this way, Patentscope, SureChEMBL and Google Patents
 became exclusive data sources for more than 21 million PubChem compounds. This study aimed to clarify
 whether the substance data supplied to PubChem by Patentscope or SureChEML could be partially incorrect. In
 PubChem, random samples with each 50 PubChem compounds exclusively sourced either from Patentscope
 SureChEMBL, or Google Patents were generated. The validity check of these sample PubChem compounds led to the result that
 the extraction process resulted in significant number of erroneous compounds. Although this result is based on
 a sample, it suggests that PubChem compounds that originate exclusively from Patentscope, SureChEMBL or Google Patents,
 to some extent, do not match the substances in the underlying patent specifications. Finally, the implications
 for PubChem users are discussed.

description: Hot Jupiters, giant extrasolar planets with orbital periods shorter than ~10 days, have long been thought to form at large radial distances, only to subsequently experience long-range inward migration. Here, we propose that in contrast with this picture, a substantial fraction of the hot Jupiter population formed in situ via the core accretion process. We show that under conditions appropriate to the inner regions of protoplanetary disks, rapid gas accretion can be initiated by Super-Earth type planets, comprising 10-20 Earth masses of refractory composition material. An in situ formation scenario leads to testable consequences, including the expectation that hot Jupiters should frequently be accompanied by additional low-mass planets with periods shorter than ~100 days. Our calculations further demonstrate that dynamical interactions during the early stages of planetary systems' lifetimes should increase the inclinations of such companions, rendering transits rare. High-precision radial velocity monitoring provides the best prospect for their detection.

Occupational Exposure to Ethylene Oxide, Myelodysplastic Syndrome, and Acute Leukemia, A Case Report
Creators: name: Windhorst, Dana John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Myelodysplastic syndromes (MDS) are a group of hematopoietic neoplasms manifest as cytopenia, and which frequently progress to leukemia. Certain agents, primarily alkylating drugs used as chemotherapy for various malignancies, can induce cytogenetic and chromosomal damage, thereby causing the MDS/leukemia progression. Ethylene oxide (EtO), an alkylating agent and suspected human leukemogen, may cause leukemia via a similar mechanism, but epidemiological studies thus far have been inconclusive. EtO exposure in association with MDS has not been previously reported. The case of an MDS/leukemia patient with an occupational history of EtO exposure is presented, the syndrome of MDS/leukemia is discussed, and cytotoxic properties of EtO are reviewed. The possible impact of this case on the question of whether EtO is a human leukemogen is discussed.

Comparison studies of SGD, MSGD, ADADELTA, ADAGRAD, ADAM/ADAMAX, RMSPROP, DOWNPOUR and EASGD/EAMSGD algorithms have been presented. Experimental results show that the distributed framework based on the message passing interface can accelerate the convergence speed at a sublinear scale. This paper demonstrates the importance of distributed training. For example, with 48 workers, a 24x speedup is achievable for the answer selection task and running time is decreased from 138.2 hours to 5.81 hours, which will increase the productivity significantly.

description: Programs with floating-point computations are often derived from mathematical models or designed with the semantics of the real numbers in mind. However, for a given input, the computed path with floating-point numbers may differ from the path corresponding to the same computation with real numbers. A common practice when validating such programs consists in estimating the accuracy of floating-point computations with respect to the same sequence of operations in an ide-alized semantics of real numbers. However, state-of-the-art tools compute an over-approximation of the error introduced by floating-point operations. As a consequence, totally inappropriate behaviors of a program may be dreaded but the developer does not know whether these behaviors will actually occur, or not. In this paper, we introduce a new constraint-based approach that searches for test cases in the part of the over-approximation where errors due to floating-point arithmetic would lead to inappropriate behaviors.
Risk Assessment Analysis on the Carcinogenic Constituents of Tobacco Smoke: ortho-toluidine and ortho-anisidine
Creators: name: Purushothaman, Shiny
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: Two compounds found in tobacco smoke, ortho-toluidine and ortho-anisidine are known animal bladder carcinogens and suspected human bladder carcinogens. Both have been linked to bladder cancer in individuals exposed in the industrial setting. This paper uses animal carcinogenicity tests of ortho- toluidine and ortho-anisidine to estimate the human risk for smoking-induced bladder cancer mortality induced by the levels of ortho-toluidine and ortho-anisidine present in cigarette smoke. Standard risk assessment methods were used for each of the compounds. Quantities inhaled from mainstream and sidestream were obtained from the literature for ortho-toluidine and ortho-anisidine. Potencies were estimated through extrapolation using the computer model Global 86 integrated through SMUSHT. The potencies were then used to calculate the lifetime risk for bladder cancer from smoking. The lifetime risk for both "light" and "heavy" smokers was calculated. The results show that ortho-toluidine and ortho-anisidine account for less than 1% of the risk for bladder cancer mortality in the observed population.

Stephen Walsh. Stravinsky: Oedipus Rex. Cambridge: Cambridge University Press, 1993. 118pp.
Creators: van den Toorn, Pieter C.
Publisher: name: Columbia University
Year: 1995
Subjects: Music

description: Anyone wishing to track down the biography of Stravinsky's opera-oratorio, Oedipus Rex, can do so fairly easily. Walsh's comments are wonderfully perceptive on the staging of Oedipus, the austere, "still life" conception envisioned initially by the composer and then also by Cocteau. Stravinsky's idea of a translation "backwards" from secular French to sacred, "monumental" Latin is discussed at length, as is the neoclassicism of the music. But it is nonetheless with the larger aesthetic issues that Walsh is primarily concerned-above all, with Stravinsky's vehement anti-individualistic stance at the time. Uncomfortable with propositions of self-expression and expressivity, the composer sought to restore distance, order, and a sense of objectivity, envisioning these as part of a removed and idealized Classical past; his stance was anti-progressive, anti-Schoenberg, anti-modernist, anti-Wagner, and so forth.

description: Dieser Beitrag basiert auf einem Dissertationsprojekt zum mündlichen korrektiven Feedback im DaZ-Unterricht in 2. und 3. Primarklassen. In sechs DaZ-Gruppen wurden je zwei Lektionen gefilmt und die Unterrichtsinteraktionen mit Blick auf rekurrente Interaktionsmuster verschiedener Reparaturtechniken und auf die Peerbeteiligung konversationsanalytisch ausgewertet. Darüber hinaus wurden die Aufnahmen jeweils am Folgetag für die videobasierte Erhebung des noticing (Wahrnehmung des korrektiven Feedbacks) sowie kurzzeitiger Lerneffekte eingesetzt. Außerdem wurden mittels Leitfadeninterviews subjektive Auskünfte der DaZ-Schüler*innen zu ihren Einstellungen zum korrektiven Feedback erhoben. Die Daten zeigen, dass prompts (Aufforderungen zur Selbstkorrektur) zu anforderungsreicheren und eigenaktiveren Formen der schüler*innenseitigen Beteiligung an der Reparatur führen, die Fokussierung auf die problematische Form begünstigen, Peerbeteiligung anregen und zudem den Präferenzen der Schüler*innen entsprechen. Aufgrund der Ergebnisse wird postuliert, dass prompts über ein höheres erwerbförderliches Potenzial als Fremdkorrekturen verfügen und es wird für mehr Anregung zu Selbstkorrekturen im DaZ-Unterricht plädiert.
description: This article is based on a dissertation investigating the oral corrective feedback in German as a Second Language (GSL) classes (grades 2 and 3) in Swiss public schools. In six GSL groups, two lessons were video recorded. The identified repair sequences were then analyzed using conversational analysis with a focus on recurrent interaction patterns and peer participation. The recordings were also used the following day for Stimulated Recall (noticing) and the video-based elicitation of linguistic forms (short- term learning effects). In addition, subjective information from GSL learners about their attitudes toward corrective feedback was collected. The findings indicate that prompts lead to more self-active and cognitively demanding forms of learner participation and support the learners’ focus on the problematic form. Furthermore, prompts promote peer participation in the repair process and correspond to the learners’ preferences. Based on the findings of this study, prompts appear to hold greater potential for language learning than other-corrections and thus should strongly be encouraged in GSL lessons.

Synchronized helicity oscillations: a link between planetary tides and the solar cycle?

description: Recent years have seen an increased interest in the question of whether the gravitational action of planets could have an influence on the solar dynamo. Without discussing the observational validity of the claimed correlations, we ask for a possible physical mechanism that might link the weak planetary forces with solar dynamo action. We focus on the helicity oscillations that were recently found in simulations of the current-driven, kink-type Tayler instability, which is characterized by an m=1 azimuthal dependence. We show how these helicity oscillations can be resonantly excited by some m=2 perturbation that reflects a tidal oscillation. Specifically, we speculate that the 11.07 years tidal oscillation induced by the Venus--Earth--Jupiter system may lead to a 1:1 resonant excitation of the oscillation of the alpha-effect. Finally, in the framework of a reduced, zero-dimensional alpha--Omega dynamo model we recover a 22.14-year cycle of the solar dynamo.

description: This thesis explores the critical fields of climate change and environmental sustainability, which examines the far-reaching consequences of human activities like greenhouse gas emissions effects which include rising sea levels and extreme weather events. Environmental sustainability prioritizes responsible resource management, considering ecological, economic, and social factors, and addressing challenges such as habitat destruction, pollution, and resource overexploitation. Amidst shifting paradigms from discourse-based to text-based documentation of research findings, this study leverages the Open Research Knowledge Graph (ORKG) to enhance the organization, comparison, and analysis of climate science research. The data for this investigation is sourced from the annual publications1 of ”The 10 New Insights in Climate Science” series, a collaborative effort initiated with the UNFCCC at the COPs since 2017 by Future Earth, the Earth League, and the World Climate Research Programme. This thesis demonstrates how the ORKG enables both broad and detailed comparisons of climate science research. Broad comparisons offer overarching views of research insights, while detailed comparisons break down contributions into specific elements like hypotheses, methodologies, results, and interpretations, fostering a deeper understanding of the research landscape. Converting text-based data into structured data is challenging and time-consuming. Conventional methods may not suffice, and this is where Language Models (LLMs) come into play. Integrating Large Language Models (LLMs), such as ChatGPT-4, to automate the extraction of insights from new research articles is crucial. The use of LLMs enhances the efficiency and scalability of data extraction, allowing researchers to concentrate on deeper analysis and interpretation. Furthermore, it can expedite the data extraction process to aid researchers. This study delves into the two primary methodologies for curating research data: human curation and LLM-based curation using a prompt. The ORKG’s structured approach enhances the discoverability, comparability, and reproducibility of climate science research, significantly advancing our understanding of climate change through systematic knowledge synthesis.
Alignment, reverse alignment, and wrong sign Yukawa couplings in two Higgs doublet models

description: We consider two Higgs doublet models with a softly broken U(1) symmetry, for various limiting values of the scalar mixing angles $α$ and $β$. These correspond to the Standard Model Higgs particle being the lighter CP-even scalar (alignment) or the heavier CP-even scalar (reverse alignment), and also the limit in which some of the Yukawa couplings of this particle are of the opposite sign from the vector boson couplings (wrong sign). In these limits we impose a criterion for naturalness by demanding that quadratic divergences cancel at one loop. We plot the allowed masses of the remaining physical scalars based on naturalness, stability, perturbative unitarity and constraints coming from the $ρ$ parameter. We also calculate the $h\to γγ$ decay rate in the wrong sign limit.
