Subjects: subject: Complex Variables (math.CV)
subject: FOS: Mathematics

description: Let $M\subset \mathbb C^n$ be a real analytic hypersurface, $M'\subset \mathbb C^N$ $(N\geq n)$ be a strongly pseudoconvex real algebraic hypersurface of the special form and $F$ be a meromorphic mapping in a neighborhood of a point $p\in M$ which is holomorphic in one side of $M$. Assuming some additional conditions for the mapping $F$ on the hypersurface $M$, we proved that $F$ has a holomorphic extension to $p$. This result may be used to show the regularity of CR mappings between real hypersurfaces of different dimensions.

History

description: This dissertation examines the interactions between early modern science and traditional Jewish legal scholarship through the life and work of Italian rabbi and physician Isaac Lampronti (1679-1756). Lampronti produced both the first alphabetically organized encyclopedia (the Paḥad Yiẓḥak) and the first periodical (the Bikurei kaẓir) of rabbinic law, which refashioned the traditional rabbinic system according to scientific methodologies and emerging Enlightenment ideas. Unwilling to relinquish the authorities of either science or traditional Jewish law, Lampronti creatively mediated the tensions between the two. The dissertation shows that the intellectual movements of the period not only catalyzed innovation within the realm of religious belief, they transformed religious practice and study as well.

Direct $ζ$-function approach and renormalization of one-loop stress tensors in curved spacetimes

Publisher: name: arXiv
Year: 1997

subject: FOS: Physical sciences

description: A method which uses a generalized tensorial $ζ$-function to compute the renormalized stress tensor of a quantum field propagating in a (static) curved background is presented. The starting point of the method is the direct computation of the functional derivatives of the Euclidean one-loop effective action with respect to the background metric. This method, when available, gives rise to a conserved stress tensor and produces the conformal anomaly formula directly. It is proven that the obtained stress tensor agrees with statistical mechanics in the case of a finite temperature theory. The renormalization procedure is controlled by the structure of the poles of the stress-tensor $ζ$ function. The infinite renormalization is automatic and is due to a ``magic'' cancellation of two poles. The remaining finite renormalization involves conserved geometrical terms arising by a certain residue. Such terms renormalize coupling constants of the geometric part of Einstein's equations (customary generalized through high-order curvature terms). The method is checked on particular cases (closed and open Einstein`s universe) finding agreement with other approaches. The method is also checked considering a massless scalar field in the presence of a conical singularity in the Euclidean manifold (i.e. Rindler spacetimes/large mass black hole manifold/cosmic string manifold). There, the method gives rise to the stress tensor already got by the point-splitting approach for every coupling with the curvature regardless of the presence of the singular curvature. Comments on the measure employed in the path integral, the use of the optical manifold and different approaches to renormalize the Hamiltonian are made.

description: It is natural to analyse the AdS$_{d+1}$-CQFT$_{d}$ correspondence in the context of the conformal- compactification and covering formalism. In this way one obtains additional inside about Rehren's rigorous algebraic holography in connection with the degree of freedom issue which in turn allows to illustrates the subtle but important differences beween the original string theory-based Maldacena conjecture and Rehren's theorem in the setting of an intrinsic field-coordinatization-free formulation of algebraic QFT. I also discuss another more generic type of holography related to light fronts which seems to be closer to 't Hooft's original ideas on holography. This in turn is naturally connected with the generic concept of ``Localization Entropy'', a quantum pre-form of Bekenstein's classical black-hole surface entropy.

Fate and form of selenium and microbiology analysis for SRF and GBBR development at Brule Mine in BC

description: Pilot-scale column trials are being used to advance Saturated Rock Fill (SRF) and Gravel Bed Bioreactor (GBBR) water treatment technologies for selenium and nitrate treatment at Conuma Resource’s Brule Mine. The operations and treatment conditions were also optimized and are covered in a separate paper titled ‘Use of Column Trials for SRF and GBBR Development for Selenium and Nitrate Treatment at Brule Mine in BC.’ The mine rock provided by Brule was characterized in detail in the context of biogeochemical treatment. These analyses showed it contains nutrients such as phosphorus and iron that decrease the need for certain reagents. Interestingly, selenium treatment occurred at a rate that was faster than nitrate treatment and independent of reagent dosing. This suggests treatment by coupled biogeochemical reactions, pairing sorption and biological reduction mechanisms. Column-scale trials had effective selenium treatment across all temperatures tested (from 4°C to 22°C). Selenium speciation and genomic microbiology profiling were done on the water during operations and on solids at decommissioning. These analyses provided insights into treatment mechanisms and confirmed that while selenium may be initially removed by sorption, it is then reduced and retained in the waste rock primarily in reduced forms. The trials undertook stress testing, including stopping reagents and exposing the substrate to oxygen. These were done in timelines that could correspond to operational challenges such as a pump malfunction or seasonal fluctuations in water levels. The results from these tests suggest minimal risk of selenium release in these stress conditions. Longer trials, such as an on-site demonstration with more selenium loading, will help better understand long-term stability and associated risks and management. Beneficial microbes, including nitrate-reducing and selenium-reducing bacteria, are naturally present in the Brule mine rock and water. These microbes are crucial for the biological treatment processes, with carbon sources like glycerol significantly enhancing microbial activity. A field-scale pilot trial is recommended to further advance the technology readiness level (TRL). A field-scale GBBR could also provide information to further inform a future SRF trial. This project highlights the potential to co-test SRF and GBBR technologies and the ability to optimize them in site-specific contexts for nitrate and selenium treatment.

Using high resolution magnetic field measurements of electrical losses, extremely narrow states with a magnetic field width reaching 1% of the matching field value are found at the commensurate points. They are accompanied by pronounced harmonic generation in response to ac modulation of the magnetic field or current. We relate these sharp anomalies to a locked commensurate state of the Mott insulator type.

Chronically ill

description: The management of chronic diseases is described as the “health challenge of the 21st century” by the World Health Organization. Patients’ active role in managing their illness is considered, by many, as central in addressing this challenge. This study explored and described, through scleroderma patients’ own perceptions and understanding, their commitment to illness management, including how they were involved in dealing with their illness and how they learned to do so. The role of social interactions, in particular, support groups, in this process was also investigated.
      Using a mixed-methods approach, 201 patients were surveyed, and 25 in-depth interviews were conducted. The quantitative results of this study indicated that 64% of patients were committed in managing their illness by being highly active in dealing with their illness. An increase in activation was associated with longer disease duration in the first decade of illness. Additionally, the patients with high social support were more active. The qualitative findings showed patients engaged with various types of work to mitigate the physical, emotional, psychological, relational, and financial impact of the illness. In doing so, patients employed four problem-solving strategies that they had learned by confronting problems in daily lives. These strategies were at the heart of their incidental and tacit learning of how to manage their illness.
      Only 32% of patients participated in support groups. Support group participants showed higher activation and considered these groups as providing support, learning opportunities, and venues to help other patients.
      This study indicates that patients’ commitment to management of their illness, far from being a static characteristic of patients, is a spectrum where patients are engaged in a process of complex negotiation with multiple needs of their illness, in tandem with their illness trajectory. Illness uncertainty, learning, and strategies to solve problems in managing the illness frame patients’ commitment and engagement. A preliminary model delineating these elements is provided.
Scientists and the Ethics of Cold War Weapons Research

description: This dissertation examines scientists' views concerning the ethics of U.S. weapons research and military advising, through the changing politics and economy of the Cold War. After the development of the atomic bomb, the Manhattan Project generation of physicists posed a series of troubling ethical questions: To what extent are scientists responsible for the military applications of their work? What are the political obligations of technical experts? What are the ideal relations among academia, industry, and the military? During the post-Sputnik science boom, many elite physicists used their policy influence to encourage government support for scientific research and to secure stronger arms control measures, an effort that culminated in the ratification of the Partial Test Ban Treaty in 1963. But after the enthusiastic expansion of science advising in the late 1950s, the war in Vietnam sorely tested scientists' support for weapons research and government work. Key controversies that elicited substantial ethical debate included the use of chemical defoliants and gases in Vietnam and the participation of the secretive Jason scientists in developing an electronic barrier to prevent North Vietnamese incursions into South Vietnam. By the end of the decade, campuses and professional societies were riven by clashes over defense contracting and academic "neutrality" in the context of the war in Vietnam. Whereas ethical debates in the aftermath of the Manhattan Project tended to be framed in individualist terms, the controversies of the late 1960s and early 1970s took place on the much larger scale of governments and institutions. The upheaval produced some changes in university contracting policies, but with ambiguous results, and the public disaffection of some top scientists led the Nixon administration to dismantle the entire Eisenhower-era presidential science advisory system. The ethical debates of the Vietnam era cast a long shadow, shifting popular attitudes toward science and heavily influencing the character of scientists' opposition to the Strategic Defense Initiative during the 1980s.

description: We present analytic cosmological solutions in a model of two-dimensional dilaton gravity with back reaction. One of these solutions exhibits a graceful exit from the inflationary to the FRW phase and is nonsingular everywhere. A duality related second solution is found to exist only in the ``pre-big-bang'' epoch and is singular at $τ= 0$. In either case back reaction is shown to play a crucial role in determining the specific nature of these geometries.

description: A search for high-mass dielectron and dimuon resonances in the mass range of 250 GeV to 6 TeV is presented. The data were recorded by the ATLAS experiment in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=$13 TeV during Run 2 of the Large Hadron Collider and correspond to an integrated luminosity of 139 fb$^{-1}$. A functional form is fitted to the dilepton invariant-mass distribution to model the contribution from background processes, and a generic signal shape is used to determine the significance of observed deviations from this background estimate. No significant deviation is observed and upper limits are placed at the 95% confidence level on the fiducial cross-section times branching ratio for various resonance width hypotheses. The derived limits are shown to be applicable to spin-0, spin-1 and spin-2 signal hypotheses. For a set of benchmark models, the limits are converted into lower limits on the resonance mass and reach 4.5 TeV for the E6-motivated $Z^\prime_ψ$ boson. Also presented are limits on Heavy Vector Triplet model couplings.

description: We describe here an experimental technique based on the acoustic scattering phenomenon allowing the direct probing of the vorticity field in a turbulent flow. Using time-frequency distributions, recently introduced in signal analysis theory, for the analysis of the scattered acoustic signals, we show how the legibility of these signals is significantly improved (time resolved spectroscopy). The method is illustrated on data extracted from a highly turbulent jet flow : discrete vorticity events are clearly evidenced. We claim that the recourse to time-frequency distributions lead to an operational definition of coherent structures associated with phase stationarity in the time-frequency plane.

Additionally, there emerge restrictions on the worldsheet curvature, which seems to act as a source for spacetime gravity, even in the absence of other matter fields.

The parametric motion of energy levels proceeds without crossing any other and the defined avoided crossings quantify the interaction between states. We propose the elimination of avoided crossings as the natural mechanism to uncover localized structures. We describe an efficient method for the elimination of avoided crossings in chaotic billiards and apply it to the stadium billiard. We find many scars of short periodic orbits revealing the skeleton on which quantum mechanics is built. Moreover, we have observed strong interaction between similar localized structures.

description: We present two-dimensional crystallization results in the square lattice for finite particle systems consisting of two different atomic types. We identify energy minimizers of configurational energies featuring two-body short-ranged particle interactions which favor some reference distance between different atomic types and contain repulsive contributions for atoms of the same type. We first prove that ground states are connected subsets of the square lattice with alternating arrangement of the two atomic types in the crystal lattice, and address the emergence of a square macroscopic Wulff shape for an increasing number of particles. We then analyze the signed difference of the number of the two atomic types, the so-called net charge, for which we prove the sharp scaling ${\rm O}(n^{1/4})$ in terms of the particle number $n$. Afterwards, we investigate the model under prescribed net charge. We provide a characterization for the minimal energy and identify a critical net charge beyond which crystallization in the square lattice fails. Finally, for this specific net charge we prove a crystallization result and identify a diamond-like Wulff-shape of energy minimizers which illustrates the sensitivity of the macroscopic geometry on the net charge.

description: It is well known that while forward scattering has no effect on the conductance of one-dimensional systems, backscattering off a static impurity suppresses the current. We study the effect of a time-dependent point impurity on the conductance of a one-channel quantum wire. At strong repulsive interaction (Luttinger liquid parameter g<1/2), backscattering renders the linear conductance greater than its value e^2/h in the absence of the impurity. A possible experimental realization of our model is a constricted quantum wire or a constricted Hall bar at fractional filling factors nu=1/(2n+1) with a time-dependent voltage at the constriction.

description: A change in boundary conditions (BC) from uniform Dirichlet to non-identical BC on the edges of a triangular billiard often brings about a dramatic change in quantum spectral fluctuations. We provide a theory for this based on periodic orbits and show that non-identical BC on adjacent edges can lead to a quantum splitting of periodic orbit families which results in a significant change in the form factor. Thus, the classical spectrum alone cannot determine quantum correlations.

description: Network embedding, as a promising way of the network representation learning, is capable of supporting various subsequent network mining and analysis tasks, and has attracted growing research interests recently. Traditional approaches assign each node with an independent continuous vector, which will cause huge memory overhead for large networks. In this paper we propose a novel multi-hot compact embedding strategy to effectively reduce memory cost by learning partially shared embeddings. The insight is that a node embedding vector is composed of several basis vectors, which can significantly reduce the number of continuous vectors while maintain similar data representation ability. Specifically, we propose a MCNE model to learn compact embeddings from pre-learned node features. A novel component named compressor is integrated into MCNE to tackle the challenge that popular back-propagation optimization cannot propagate through discrete samples. We further propose an end-to-end model MCNE$_{t}$ to learn compact embeddings from the input network directly. Empirically, we evaluate the proposed models over three real network datasets, and the results demonstrate that our proposals can save about 90\% of memory cost of network embeddings without significantly performance decline.

description: Genetic screens have laid much of the groundwork for our current understanding of biology, and mutagenesis screens in Caenorhabditis elegans have proven to be a particularly useful tool in determining the molecular components of biological processes. The Million Mutation Project (MMP) is a collection of mutagenized C. elegans strains that have been clonally propagated and whole-genome sequenced. Utilizing the MMP, I have performed a screen for touch insensitive mutants to assess the phenotypic coverage of the set, to obtain new alleles of known genes, and to potentially identify touch phenotype-causing mutations in genes that have not yet been linked to the touch response. In this thesis I first present my rationale for screening the MMP set for touch phenotypes, then review what has already been learned about genes required for the function of the neurons that sense gentle touch in C. elegans. I describe my approach to phenotyping the MMP set and present statistics on response distributions. As expected, most of the MMP strains that I determined to have strong touch insensitive phenotypes had mutations in genes identified in previous touch phenotype mutageneses. However, some of the phenotype-causing MMP alleles cause protein-coding changes in regions that were not known to be affected by previously characterized alleles. The genomic data from the MMP also allowed me to consider protein-altering mutations in known touch genes that did not result in a detectable phenotype. Finally, I address the set of strains for which we have not identified candidate causative mutations. Although I have not discovered any previously unknown touch genes through my screen of the MMP, it is still quite possible that the touch insensitive mutants I have identified will lead us to identify additional genes needed for gentle touch sensation. Ultimately, my screen has successfully demonstrated the utility of the MMP set and provided new insights as to the structure and function of the genetic determinants of gentle touch sensation in C. elegans.

description: The horizon area and curvature of three-charge BPS black strings are studied in the D-brane ensemble for the stationary black string. The charge distributions along the string are used to translate the classical expressions for the horizon area and curvature of BPS black strings with waves into operators on the D-brane Hilbert space. Despite the fact that any `wavy' black string has smaller horizon area and divergent curvature, the typical values of the horizon area and effects of the horizon curvature in the D-brane ensemble deviate negligibly from those of the original stationary black string in the limit of large integer charges. Whether this holds in general will depend on certain properties of the quantum bound states.

description: Il saggio affronta la ricezione intermediale del racconto di Henry James «The Beast in the Jungle» nel cinema francese della Nouvelle Vague e in quello successivo. Interrogandosi sulla funzione della citazione del racconto di James nel film di Patrice Leconte’s Confidences trop intimes (2004), il saggio la legge come il segnale di una doppia operazione intertestuale. Da un lato, il film di Leconte è una sofisticata appropriazione e riscrittura della storia originale; dall’altro lato, attraverso il riferimento a «The Beast in the Jungle», Confidences trop intimes a un tempo nasconde e rivela il proprio rapporto con il più celebre adattamento cinematografico del racconto jamesiano, La Chambre verte di François Truffaut.

description: Full counting statistics (FCS) of charge transfer in mesoscopic systems has recently become a subject of significant interest, since it proves to reveal an important information about the system which can be hardly assessed by other means. While the previous research mostly addressed the FCS of non- interacting systems, the present paper deals with the FCS in the limit of strong interaction. In this Coulomb blockade limit the electron dynamics is known to be governed by a master equation. We develop a general scheme to evaluate the FCS in such case, this being the main result of the work presented. We illustrate the scheme, by applying it to concrete systems. For generic case of a single resonant level we establish the equivalence of scattering and master equation approach to FCS. Further we study a single Coulomb blockade island with two and three leads attached and compare the FCS in this case with our recent results concerning an open dot either with two and three terminals. We demonstrate that Coulomb interaction suppresses the relative probabilities of large current fluctuations.

description: Surfactant driven “Marangoni” flows can be used to cause material transport along interfaces. One potential use of this is to cause post deposition transport of aerosolized drug used to treat lung diseases such as cystic fibrosis. The work in this thesis explores the underlying science of such a treatment by studying the transport properties in three different ways. First, I explore the ability of the lung’s natural surfactants (lipids) to transport drug across a mucus-like subphase. This work shows that lipid can drive such spreading and can even do so in low surface tension environments, such as the lung. Second, I develop an apparatus to study the effects of subphase height and surfactant amount on spreading and non-surface active material transport. The effects on flow behavior are mapped into an operating diagram and other transport properties are tracked and related to three distinct flow regimes. Lastly, I simulate the interactions of two spreading disks of surfactant to bring research closer to the case of aerosol
deposition where multiple sources of Marangoni stress are present. From this work, I explore the effects of two surfactant sources on flow behavior. This thesis provides powerful insights into surfactant driven drug delivery and offers several future research directions which will advance the field.

description: A braided subfactor determines a coupling matrix Z which commutes with the S- and T-matrices arising from the braiding. Such a coupling matrix is not necessarily of "type I", i.e. in general it does not have a block-diagonal structure which can be reinterpreted as the diagonal coupling matrix with respect to a suitable extension. We show that there are always two intermediate subfactors which correspond to left and right maximal extensions and which determine "parent" coupling matrices Z^\pm of type I. Moreover it is shown that if the intermediate subfactors coincide, so that Z^+=Z^-, then Z is related to Z^+ by an automorphism of the extended fusion rules. The intertwining relations of chiral branching coefficients between original and extended S- and T-matrices are also clarified. None of our results depends on non-degeneracy of the braiding, i.e. the S- and T-matrices need not be modular. Examples from SO(n) current algebra models illustrate that the parents can be different, Z^+\neq Z^-, and that Z need not be related to a type I invariant by such an automorphism.

description: This work presents the search for Dark Matter particles associated with the Higgs Boson decaying into a b b-bar quark pair. The dark matter search result is based on proton-proton collision data collected at a center-of-mass energy of 13 TeV by the ATLAS detector during Run II. The results are interpreted in the context of a simplified model (Z’-2HDM) which describes the interaction of dark matter and standard model particles via new heavy mediator particles. The new powerful Higgs tagging techniques, which exploit the jet substructure and heavy flavor information to a large extent, are developed to improve the search sensitivity of the search. The target physics signals are signature with an optimized search region and interpreted with background estimation result statistically.
