description: The goal of this paper is to analyse the method of angular quantization for the Sine-Gordon model at the free fermion point, which is one of the most investigated models of the two-dimensional integrable field theories. The angular quantization method (see hep-th/9707091) is a continuous analog of the Baxter's corner transfer matrix method. Investigating the canonical quantization of the free massive Dirac fermions in one Rindler wedge we identify this quantization with a representation of the infinite-dimensional algebra introduced in the paper q-alg/9702002 and specialized to the free fermion point. We construct further the main ingredients of the SG theory in terms of the representation theory of this algebra following the approach by M.Jimbo, T.Miwa et al.

description: Let X=(Xt)t≥0 be a known process and T an unknown random time independent of X. Our goal is to derive the distribution of T based on an iid sample of XT. Belomestny and Schoenmakers (Stoch Process Appl 126(7):2092–2122, 2015) propose a solution based the Mellin transform in case where X is a Brownian motion. Applying their technique we construct a non-parametric estimator for the density of T for a self-similar one-dimensional process X. We calculate the minimax convergence rate of our estimator in some examples with a particular focus on Bessel processes where we also show asymptotic normality.

Traffic safety

description: Streets in the cities are a crucial element of human life. However, it is not safe enough that every year over 37,000 people die in road crashes in the US. The thesis aims to research as a planner, how could design methods and planning strategies enhance street safety in large cities. The research uses mixed methods that combine data analysis and site observation to explore how safety improvement present and influence the condition of streets. Several preliminary models have been conducted by data analysis. Site observation acts as supplementation of data analysis to merge the theoretical model into the practical world and observe the elements that could not be revealed by data. In the end, a framework has created for future improvement and development. Also, there are some limitations to the study that could be improved by future studies.

description: $Γ$-conformal algebra is an axiomatic description of the operator product expansion of chiral fields with simple poles at finitely many points. We classify these algebras and their representations in terms of Lie algebras and their representations with an action of the group $Γ$. To every $Γ$-conformal algebra and a character of $Γ$ we associate a Lie algebra generated by fields with the OPE with simple poles. Examples include twisted affine Kac-Moody algebras, the sin algebra (which is a ``$Γ$-conformal'' analodue of the general linear algebra) and its analogues, the algebra of pseudodifferential operators on the circle, etc.

description: We consider a quantum particle in a waveguide which consists of an infinite straight Dirichlet strip divided by a thin semitransparent barrier on a line parallel to the walls which is modeled by a $δ$ potential. We show that if the coupling strength of the latter is modified locally, i.e. it reaches the same asymptotic value in both directions along the line, there is always a bound state below the bottom of the essential spectrum provided the effective coupling function is attractive in the mean. The eigenvalues and eigenfunctions, as well as the scattering matrix for energies above the threshold, are found numerically by the mode-matching technique. In particular, we discuss the rate at which the ground-state energy emerges from the continuum and properties of the nodal lines. Finally, we investigate a system with a modified geometry: an infinite cylindrical surface threaded by a homogeneous magnetic field parallel to the cylinder axis. The motion on the cylinder is again constrained by a semitransparent barrier imposed on a ``seam'' parallel to the axis.

Fig. 37
 Serrataginella beatrix Cossignani, 2001: 13-14.
TYPE MATERIAL. — Holotype (dd) MNHN 0370, 1 paratype MMM.
TYPE LOCALITY. — Northern New Caledonia, Grand Passage.
 MATERIAL EXAMINED. — Northern New Caledonia. TUI 2 (private expedition), Grand Passage, 250-270 m, 1 dd (holotype, Fig. 37).
DISTRIBUTION. — Northwestern tip of New Caledonia, shells in 250-270 m.
DESCRIPTION. — Shell pyriform, light, opaque. Protoconch paucispiral, wide, dome-shaped, smooth. Spire short, teat-like, one whorl. Aperture narrow, oblique. Base tapering. Outer lip thick, slightly more reflected over its middle part, shoulder rounded, outer edge arched over its posterior part, rather straight over its anterior part, outer margin thickened, wide, stepped. Inner edge bearing about 14 very weak, quite indistinct, labial denticles. Four columellar plaits, first subvertical, very angled at its posterior part, 3 uppermost plaits horizontal, decreasing in size.
Ground colour whitish, spire pale orange, 2 wide spiral bands on the last whorl, encompassing the whole outer margin, base of the columella and siphonal canal intense white.
Dimensions: 6.63 x 3.70 mm.
Radula unknown.
 REMARKS. — In its suboval outline and its narrow aperture, Serrata beatrix closely resembles the French Polynesian Serrata translata (Fig. 4). Serrata beatrix differs from S. translata by its more pyriform outline, its more protruding spire, its slightly less narrow aperture, its more flexuous outer lip, its angled first columellar plait and its horizontal 3 uppermost plaits.
 The species was described originally in the genus Serrataginella, here considered a junior synonym of Serrata. Furthermore, the shell morphology of S. beatrix seems to be closer to S. translata than to the East African “ Marginella ” spryi Clover, 1974, type species of Serrataginella.

description: The recognition that large classes of quantum many-body systems have limited entanglement in the ground and low-lying excited states led to dramatic advances in their numerical simulation via so-called tensor networks. However, global dynamics elevates many particles into excited states, and can lead to macroscopic entanglement and the failure of tensor networks. Here, we show that for quantum transport -- one of the most important cases of this failure -- the fundamental issue is the canonical basis in which the scenario is cast: When particles flow through an interface, they scatter, generating a "bit" of entanglement between spatial regions with each event. The frequency basis naturally captures that -- in the long-time limit and in the absence of inelastic scattering -- particles tend to flow from a state with one frequency to a state of identical frequency. Recognizing this natural structure yields a striking -- potentially exponential in some cases -- increase in simulation efficiency, greatly extending the attainable spatial- and time-scales, and broadening the scope of tensor network simulation to hitherto inaccessible classes of non-equilibrium many-body problems.

title: Policing in a Lawless Society: A Study of Police Legitimacy and Procedural Justice in Nigeria
Creators: name: Akinlabi, Oluwagbenga Michael
Publisher: name: Griffith University
Year: 2016
Subjects: subject: Policing, Nigeria
subject: Law and order, Nigeria

description: This thesis makes a number of contributions to the literature on procedural justice and police legitimacy. It does so using a sample of respondents from Nigeria. It explores whether public perceptions of procedural justice are more or less influential than perceptions of police effectiveness in determining whether police will be perceived as legitimate, and by extension, foster people’s self-reported willingness to voluntary comply with the law and cooperate with police. Studies mostly from US, UK, and Australia strongly suggest police legitimacy as a mediating factor between perceptions of procedural justice and self-reported law-abiding behaviour (such as compliance with the law and willingness to cooperate with police). However, this perspective contradicts findings from Africa; here, studies show that police are most likely to engender legitimacy or motivate compliance related behaviour when the police are perceived to be effective in crime control, use sanction, and threats of force. The findings of the current thesis support both perspectives.

description: Structural chirality plays an important role in solid state physics and leads to a variety of novel physics. The feasibility of probing structural chirality of crystals using high harmonic generation in solids is explored in this work. Through first-principles calculations based on the time-dependent density functional theory framework, we demonstrate that evident circular dichroism (CD) effects can be induced in the high harmonic spectra from a chiral crystal -- bulk tellurium. The CD signal reverses for crystals with opposite structural chirality. Besides, the high harmonic spectroscopy also provides an all-optical method for probing lattice symmetry properties and determining orientation of the tellurium crystal.

HOW AN ALTERNATIVE VERSION OF STR EXPLAINS THE EXISTENCE OF ANTIMATTER, ANTI-SPACE AND ANTI-TIME?

description: The article shows that the special theory of relativity (STR) created in the last century was based on postulates due to the lack of the required experimental information and turned out to be incorrect, as its principle of light speed non-exceedance was refuted by studies of special processes in linear electric circuits in the 21st century. And thus, it made obsolete the unsuccessful OPERA and ICARUS experiments carried out at the Large Hadron Collider. Therefore, an alternative version of the STR has been proposed. Its relativistic formulas imply the existence of numerous mutually invisible parallel universes and antiverses. It is explained how they can be seen. There is antimatter, as well as anti-space and anti-time in antiverses.

description: Methods for improving the technological operation of combined trains at intermediate stations within the railway transport sections were studied. A technological scheme of processing the combined train was created at the intermediate station. Based on mathematical modeling, a graph of the dependence of the shunting composition on the speed of movement of the half-flight times was developed. The developed scheme and graph allow to determine the optimal number of shunting semicircles at intermediate stations and to set the time norms correctly. This, in turn, leads to an increase in the performance of intermediate stations and a reduction in inefficient downtime of trains and wagons.

description: In a recent paper, we introduced a new discretization scheme for gravity in 2+1 dimensions. Starting from the continuum theory, this new scheme allowed us to rigorously obtain the discrete phase space of loop gravity, coupled to particle-like "edge mode" degrees of freedom. In this work, we expand on that result by considering the most general choice of integration during the discretization process. We obtain a family of polarizations of the discrete phase space. In particular, one member of this family corresponds to the usual loop gravity phase space, while another corresponds to a new polarization, dual to the usual one in several ways. We study its properties, including the relevant constraints and the symmetries they generate. Furthermore, we motivate a relation between the dual polarization and teleparallel gravity.

description: High thermal conductivity (TC) and a tunable coefficient of thermal expansion are essential properties for heat management materials operating in a wide temperature range. We combine both properties in a composite with a low‐density metal matrix reinforced with pitch‐based carbon fibres. The thermal conductivity of the metal matrix was increased by 50%, the thermal expansion coefficient was reduced by a factor of five. The samples were produced by powder metallurgy and have a planar random distribution of fibres, leading to high performance in two dimensions.

description: The $h$-deformed quantum plane is a counterpart of the $q$-deformed one in the set of quantum planes which are covariant under those quantum deformations of GL(2) which admit a central determinant. We have investigated the noncommutative geometry of the $h$-deformed quantum plane. There is a 2-parameter family of torsion-free linear connections, a 1-parameter sub-family of which are compatible with a skew-symmetric non-degenerate bilinear map. The skew-symmetric map resembles a symplectic 2-form and induces a metric. It is also shown that the extended $h$-deformed quantum plane is a noncommutative version of the Poincaré half-plane, a surface of constant negative Gaussian curvature.

description: Grand gauge-Higgs unification of five dimensional $SU(6)$ gauge theory on an orbifold $S^1/Z_2$ is discussed. The Standard model (SM) fermions are introduced on one of the boundaries and some massive bulk fields are also introduced so that they couple to the SM fermions through the mass terms on the boundary. Integrating out the bulk fields generates the SM fermion masses with exponentially small bulk mass dependences. The SM fermion masses except for top quark are shown to be reproduced by mild tuning the bulk masses. One-loop Higgs potential is calculated and it is shown that the electroweak symmetry breaking occurs by introducing additional bulk fields. Higgs boson mass is also computed.

Design Techniques for Frequency Synthesizers in Highly Scaled CMOS Technologies
Creators: Yu, Shih-An
Publisher: name: Columbia University
Year: 2012
Subjects: Electrical engineering

description: While extremely scaled CMOS transistors are believed to cause many design concerns especially for conventional analog circuits, CMOS technology scaling, on the other hand, has also opened up new opportunities for analog and mixed-mode circuit designs to mitigate design challenges by the speed improvement and the high density of the nanometer devices. Phase-locked-loop-based frequency synthesizers are essential building blocks in almost all the communication systems. The design of PLLs is a true mixed signal design challenge covering from high speed analog and RF blocks (VCO), to high speed digital blocks (dividers), to low speed analog (charge pump and loop filter) and low speed digital (phase frequency detector) circuits. In this thesis, we study design challenges and present corresponding solutions to realize PLLs in the nano-scale CMOS era. In particular we focus on supply voltage scaling, area scaling, ultra-wide frequency range, and ultra-low noise performance. An ultra low voltage (ULV) 2.5-GHz GFSK modulator implemented in a 90-nm CMOS technology using only standard digital regular Vt (RVT) devices will first be introduced to address robustness concerns and speed issues due to the supply voltage scaling (down to 0.5V). Then, a 2.5-GHz ultra-compact (150um x 280um) analog PLL implemented in a 45-nm CMOS technology with a fully integrated LC-VCO and an on-chip passive R-C loop filter will further be used to show that area scaling can indeed be achieved for a PLL through a rigorous area-scaling scheme of LC oscillators and a new loop filter structure. New emerging applications such as software-defined radios or highly integrated test instrumentation require the PLL synthesizer to have ultra wide bandwidth and ultra low phase noise. We will present the approaches to mitigate these challenging design objectives by exploiting the capabilities of nanometer transistors. A wideband synthesizer covering from 125MHz to 32GHz with a constant performance across the entire frequency range will be presented; the scaling schemes and design methodologies to achieve constant noise performance across the ultra-wide frequency range will be discussed. Finally, an ultra low noise fractional-N synthesizer will be presented to show how low phase noise fractional-N frequency synthesis can be achieved by taking the full advantage of nano-scale CMOS transistors.
Design Techniques for Analog-to-Digital Converters in Scaled CMOS Technologies
Creators: Kuppambatti, Jayanth Narasimhan
Publisher: name: Columbia University
Year: 2014
Subjects: Electrical engineering

description: Analog-to-digital converters (ADCs) are analog pre-processing systems that convert the real life analog signals, the input of sensors or antenna, to digital bits that are processed by the system digital back-end. Due to the various issues associated with CMOS technology scaling such as reduced signal swings and lower transistor gains, the design of ADCs has seen a number of challenges in medium to high resolution and wideband digitization applications. The various chapters of this thesis focus on efficient design techniques for ADCs that aim to address the challenges associated with design in scaled CMOS technologies.
      This thesis discusses the design of three analog and mixed-signal prototypes: the first prototype introduces current pre-charging (CRP) techniques to generate the reference in Multiplying Digital-to-Analog Converters (MDACs) of pipeline ADCs. CRP techniques are specifically applied to Zero-Crossing Based (ZCB) Pipeline-SAR ADCs in this work. The proposed reference pre-charge technique relaxes power and area requirements for reference voltage generation and distribution in ZCB Pipeline ADCs, by eliminating power hungry low impedance reference voltage buffers. The next prototype describes the design of a radiation-hard dual-channel 12-bit 40MS/s pipeline ADC with extended dynamic range, for use in the readout electronics upgrade for the ATLAS Liquid Argon Calorimeters at the CERN Large Hadron Collider. The design consists of two pipeline A/D channels with four MDACs with nominal 12-bit resolution each, that are verified to be radiation-hard beyond the required specifications.
      The final prototype proposes Switched-Mode Signal Processing, a new design paradigm that achieves rail-to-rail signal swings with high linearity at ultra-low supply voltages. Switched-Mode Signal Processing represents analog information in terms of pulse widths and replaces the output stage of OTAs with power-efficient rail-to-rail Class-D stages, thus producing Switched-Mode Operational Amplifiers (SMOAs). The SMOAs are used to implement a Programmable Gain Amplifier (PGA) that has a programmable gain from 0-12dB.

description: Influenza H3N8 viruses have been recovered frequently from wild bird species， including Anseriformes (primarily from migratory ducks) and Charadriiformes (primarily from shorebirds). However, little attention has been given to the transmission ability of H3N8 avian influenza viruses among mammals. Here, we study the potential human health threat and the molecular basis of mammalian transmissibility of H3N8 avian influenza viruses isolated from wild bird reservoirs. We classified eight H3N8 viruses into seven different genotypes based on genomic diversity. Six of eight H3N8 viruses isolated naturally from wild birds have acquired the ability to bind to the human-type receptor. However, the affinity for α-2,6-linked SAs was lower than that for α-2,3-linked SAs. Experiments on guinea pigs demonstrated that three viruses transmitted efficiently to direct-contact guinea pigs without prior adaptation. Notably, one virus transmitted efficiently via respiratory droplets in guinea pigs but not in ferrets. We further found that the PB1 S524G mutation conferred T222 virus airborne transmissibility between ferrets. We also determined that the 524G mutant increased viral pathogenicity slightly in mice compared with the WT (wild type). Based on these results, we elucidated the potential human health threat and molecular basis of mammalian transmissibility of H3N8 influenza viruses. We emphasized the need for continued surveillance of the H3N8 influenza viruses circulating in birds.

Searching for light WIMPS in view of neutron decay to dark matter

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In the present work we examine the implications on dark matter searches of the possibility of a partial decay of a neutron into a dark matter particle, slightly lighter than itself. Such a scenario recently proposed is required to bridge the discrepancy between the results of two different experiments measuring the life time of the neutron. It was subsequently suggested that this light dark matter candidate could make up the whole of dark matter in the universe. We thus first compute the nucleon cross section based on such models. Then we proceed explore the various signatures appearing in dark matter searches involving nuclear targets, in the case of such a light dark matter candidate.

description: The absorption, distribution and metabolism of various ligands in organisms are particularly important for understanding biological systems and processes. Herein, this work presents the detail in the interaction between 3-hydroxy-2,2′,4,4′-tetrabromodiphenyl ether and human serum albumin. Small molecule of ligand cause the endogenous fluorescence of human serum albumin to be quenched, and the quenching mechanism includes static quenching, dynamic quenching and non-radiative energy transfer. Synchronous fluorescence and site competition experiments demonstrate that 3-hydroxy-2,2′,4,4′-tetrabromodiphenyl ether has one binding site with human serum albumin (site I). In addition, similar conclusions are obtained from the molecular docking experiment. Molecular dynamics confirms that human serum albumin bound with 3-hydroxy-2,2′,4,4′-tetrabromodiphenyl ether has more compact structure and increased hydrophobicity. Circular dichroism spectra exhibites that the α-helix of the complex are reduced by 21.2% relative to free human serum albumin. More importantly, thermodynamic reveals that hydrophobic interaction is identified as the primary driving force for the formation of the complex. This work provides valuable reference for the mechanism of interaction between organic pollutants and human serum albumin by multiple-spectra and theoretical simulation.

description: We propose a method to transfer pose and expression between face images. Given a source and target face portrait, the model produces an output image in which the pose and expression of the source face image are transferred onto the target identity. The architecture consists of two encoders and a mapping network that projects the two inputs into the latent space of StyleGAN2, which finally generates the output. The training is self-supervised from video sequences of many individuals. Manual labeling is not required. Our model enables the synthesis of random identities with controllable pose and expression. Close-to-real-time performance is achieved.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: In the structure of primary drug resistance in Khabarovski Krai in 2017 polyresistance was discovered in 18.1% of bacteriostatic agents, multidrug resistance (MDR) in 68.1% of bacteriostatic agents. In the structure of MDR most common was resistance to a combination of three main-line anti-TB drugs: streptomycin, isoniazid, and rifampicin. Wide drug resistance was discovered in 0.9%. According to the prognostic model, in 2020 in Khabarovski Krai we expect the prevalence of patients with MDR MBT in the structure of primary resistance, which will make a negative impact on the effectiveness of treatment and give prerequisites for the progression of the disease with a mutation of the MBT strain to wide drug resistance. Estimation of drug resistance is necessary to estimate the spreading of m. Tuberculosis with MDR, to develop additional anti-epidemic measures at the regional level, to substantiate the choice of optimal chemoprophylactic treatment regimens for people at risk.
