description: The structure of single atoms in real space is investigated by scanning tunneling microscopy. Very high resolution is possible by a dramatic reduction of the tip-sample distance. The instabilities which are normally encountered when using small tip-sample distances are avoided by oscillating the tip of the scanning tunneling microscope vertically with respect to the sample. The surface atoms of Si(111)-(7 x 7) with their well-known electronic configuration are used to image individual samarium, cobalt, iron and silicon atoms. The resulting images resemble the charge density corresponding to 4f, 3d and 3p atomic orbitals.

description: We study the total gravitating mass distribution in the central region of 23 clusters of galaxies with Chandra. Using a new deprojection technique, we measure the temperature and gas density in the very central region of the clusters as a function of radius without assuming any particular models. Under the assumptions of hydrostatic equilibrium and spherical symmetry, we obtain the deprojected mass profiles of these clusters. The mass profiles are nicely scalable with a characteristic radius ($r_{200}$) and mass ($M_{200}$) on the large scale of $r>0.1r_{200}$. In contrast, the central ($r<0.1r_{200}$) mass profiles have a large scatter even after the scaling. The inner slope $α$ of the total mass density profile ($ρ(r) \propto r^{-α}$) is derived from the slope of the integrated mass profile. The values of the inner slope $α$ at the radius of $0.02r_{200}$ ($α_0$) span a wide range from 0 to 1.2. For 6 out of 20 clusters, $α_0$ is lower than unity at a 90 % confidence level. CDM simulations predict that the inner slope $α$ is in the range $1

description: Silicon nanowires have been studied and used as high-sensitivity, restricted labelling and high detection sensors in the last decade. The development of SiNW biosensors and their diagnostic applications are discussed here. Biomarkers related to cancer, coronary diseases, infectious diseases, and other diseases are analysed. SiNW biochemistry is a great promising tool for encouraging the creation and application of POC instruments for disease diagnosis. It investigates the use of nanomaterials in biomedical sensors, such as carbon nanotubes, nanoparticles, quantum points and nanowires. For sensitivity and durability, a large area-to-volume ratio is necessary. We assess the working principle of nanowire structures and comprehensive manufacturing processes. Moreover, experiments have been checked on the use of the sample for the detection of biomarkers, viruses and DNA, and the finding of drugs. Recent breakthroughs are investigated in self-power, reusability, sensitivity and long-term stability in high ionic strength solutions. Due to their high conductivity, Nanowire can improve the sensitivity of biomedical sensors.

description: Extending the cavity length of diode lasers with feedback from Bragg structures and ring resonators is highly effective for obtaining ultra-narrow laser linewidths. However, cavity length extension also decreases the free-spectral range of the cavity. This reduces the wavelength range of continuous laser tuning that can be achieved with a given phase shift of an intracavity phase tuning element. We present a method that increases the range of continuous tuning to that of a short equivalent laser cavity, while maintaining the ultra-narrow linewidth of a long cavity. Using a single-frequency hybrid integrated InP-Si3N4 diode laser with 120 nm coverage around 1540 nm, with a maximum output of 24 mW and lowest intrinsic linewidth of 2.2 kHz, we demonstrate a six-fold increased continuous and mode-hop-free tuning range of 0.22 nm (28 GHz) as compared to the free-spectral range of the laser cavity.

description: Charge separated interlayer excitons in transition metal dichalcogenide (TMDC) heterobilayers are being explored for moiré exciton lattices and exciton condensates. The presence of permanent dipole moments and the poorly screened Coulomb interaction make many body interactions particularly strong for interlayer excitons. Here we reveal two distinct phase transitions for interlayer excitons in the MoSe2/WSe2 heterobilayer using time and spatially resolved photoluminescence imaging: from trapped excitons in the moiré-potential to the modestly mobile exciton gas as exciton density increases to ne/h ~ 1011 cm-2 and from the exciton gas to the highly mobile charge separated electron/hole plasma for ne/h > 1012 cm-2. The latter is the Mott transition and is confirmed in photoconductivity measurements. These findings set fundamental limits for achieving quantum states of interlayer excitons.

description: Unsupervised learning involves inferring the inherent structures or patterns from unlabeled data. Since there is no label information, the fundamental challenge of unsupervised learning is that the objective function is not explicitly defined. The ubiquity of large-scale datasets adds another layer of complexity to the overall learning problem. When the data size or dimension is large, even algorithms with quadratic runtime may be prohibitive. This thesis presents four large-scale unsupervised learning problems. We start with two density estimation problems: given samples from a one-layer ReLU generative model or a discrete pairwise graphical model, the goal is to recover the parameters of the generative model. We then move to representation learning of high-dimensional sparse data coming from one-hot encoded categorical features. We assume that there are additional but a-priori unknown structures in their support. The goal is to learn a lossless low-dimensional embedding for the given data. Our last problem is to compute low-rank approximations of a matrix product given the individual matrices. We are interested in the setting where the matrices are too large and can only be stored in the disk. For every problem presented in this thesis, we (i) design novel and efficient algorithms to capture the inherent structure from data in an unsupervised manner; (ii) establish theoretical guarantees and compare the empirical performance with the state-of-the-art methods; and (iii) provide source code to support our experimental findings

description: Noncommutative Maxwell-Chern-Simons theory in 3-dimensions is defined in terms of star product and noncommutative fields. Seiberg-Witten map is employed to write it in terms of ordinary fields. A parent action is introduced and the dual action is derived. For spatial noncommutativity it is studied up to second order in the noncommutativity parameter θ. A new noncommutative Chern-Simons action is defined in terms of ordinary fields, inspired by the dual action. Moreover, a transformation between noncommuting and ordinary fields is proposed.

description: Using a representation of multichannel quantum defect theory in terms of a quantum Poincaré map for bound Rydberg molecules, we apply Jung's scattering map to derive a generalized quantum map, that includes the continuum. We show, that this representation not only simplifies the understanding of the method, but moreover produces considerable numerical advantages. Finally we show under what circumstances the usual semi-classical approximations yield satisfactory results. In particular we see that singularities that cause problems in semi-classics are irrelevant to the quantum map.

 Comments. This species was described from the three close localities in eastern Nepal (Logunov 2003), from the elevations 1900–2010 m. The new record lies at about 760 m, thus extending the altitudinal distribution of the species by some 1100 m lower. The species can be collected by sweeping over or beating off vegetation in the Lithocarpus /Casatanopsis - and Ericacea -sclerophyll forests (Logunov 2003) and from under stones (present data).
 Colour photographs of C. chichila (Figs 1–3, 5) are presented here for the first time; the body colour and colour pattern of the studied female correspond to and are complementary with those given in the detailed description by Logunov (2003: 581).

description: O objetivo do artigo foi analisar a viabilidade da utilização de modelos de séries temporais univariadas como instrumentos de apoio à tomada de decisão. A análise empírica consistiu em realizar um estudo de caso sobre a previsão do preço recebido pelo suíno brasileiro. Foi considerada a série de preços coletada junto ao banco de dados do IPEA no período 01/1994 a 12/2003, verificando-se a potencialidade de previsão dos modelos no período 01/2004 a 12/2004, sendo as previsões realizadas um passo a frente. Estimaram-se modelos de séries temporais ARIMA, SARIMA e GARCH e avaliaram-se a potencialidade de previsão e utilização desses modelos como instrumentos de apoio à tomada de decisão. Os resultados indicaram que os três modelos são viáveis por apresentarem baixo Erro Percentual de Previsão, sendo os mais eficazes o GARCH e SARIMA. Assim, ao utilizar tais métodos, os agentes integrados na comercialização de suínos podem alocar melhor seus recursos, no curto prazo, visando diminuir seus riscos e elevar suas margens de retorno.

description: The role that occupied $d$ bands play in the inelastic lifetime of bulk and surface states in Ag is investigated from the knowledge of the quasiparticle self-energy. In the case of bulk electrons, $sp$ bands are taken to be free-electron like. For surface states, the surface band structure of $sp$ states is described with the use of a realistic one-dimensional hamiltonian. The presence of occupied $d$ states is considered in both cases by introducing a polarizable background. We obtain inelastic lifetimes of bulk electrons that are in good agreement with first-principles band-structure calculations. Our surface-state lifetime calculations indicate that the agreement with measured lifetimes of both crystal-induced and image-potential induced surface states on Ag(100) and Ag(111) is considerably improved when the screening of $d$ electrons is taken into account.

description: Materials undergoing both phase separation and chemical reactions (defined here as all processes that change particle type or number) form an important class of non-equilibrium systems. Examples range from suspensions of self-propelled bacteria with birth-death dynamics, to bio-molecular condensates, or 'membraneless organelles', within cells. In contrast to their passive counterparts, such systems have conserved and non-conserved dynamics that do not, in general, derive from a shared free energy. This mismatch breaks time-reversal symmetry and leads to new types of dynamical competition that are absent in or near equilibrium. We construct a canonical scalar field theory to describe such systems, with conserved and non-conserved dynamics obeying Model B and Model A respectively (in the Hohenberg-Halperin classification), chosen such that the two free energies involved are incompatible. The resulting minimal model is shown to capture the various phenomenologies reported previously for more complicated models with the same physical ingredients, including microphase separation, limit cycles and droplet splitting. We find a low-dimensional subspace of parameters for which time-reversal symmetry is accidentally recovered, and show that here the dynamics of the order parameter field (but not its conserved current) is exactly the same as an equilibrium system in which microphase separation is caused by long-range attractive interactions.

description: A variational principle for determining unstable periodic orbits of flows as well as unstable spatio-temporally periodic solutions of extended systems is proposed and implemented. An initial loop approximating a periodic solution is evolved in the space of loops toward a true periodic solution by a minimization of local errors along the loop. The ``\descent'' partial differential equation that governs this evolution is an infinitesimal step version of the damped Newton-Raphson iteration. The feasibility of the method is demonstrated by its application to the Hénon-Heiles system, the circular restricted three-body problem, and the Kuramoto-Sivashinsky system in a weakly turbulent regime.

description: The maker movement refers to individual or collective do-it-yourself practices that make use of digital manufacturing in fields as varied as daily life, research, and industry. These practices are deployed in physical spaces called makerspaces. This generic term designates technological spaces of open innovation that are alternatively called fab labs, hubs, accelerators, incubators, hackerspaces, biohackerspaces, living labs, or coworking spaces. Makerspaces are generally equipped with digitally controlled machines, such as 3D printers or laser cutters, computer equipment, electronic kits, and a variety of other equipment or tools, like saws or sewing machines. Beyond the material aspect, makerspaces are characterized by their community dimension: regardless of their field, people with similar interests can come together to socialize, to collaborate, and to discuss common themes and problems. However, the maker movement—it is worth mentioning—is not a new phenomenon. As Michel Lallement says, “We have always been makers.”[1] This is all the more true in the African context, where resourcefulness, DIY, recycling, and repairing/mending practices are anchored in daily life. With an estimated over 100 makerspaces in Africa,[2] this ever-increasing expansion cannot go unnoticed.

description: The modified XY model is a modification of the XY model by addition of a half-periodic term. The modified Goldstone model is a regular and continuum version of the modified XY model. The former admits a vortex molecule, that is, two half-quantized vortices connected by a domain wall, as a regular topological soliton solution to the equation of motion while the latter admits it as a singular configuration. Here we define the ${\mathbb Z}_n$ modified XY and Goldstone models as the $n=2$ case to be the modified XY and Goldstone models, respectively. We exhaust all stable and metastalble vortex solutions for $n=2,3$ and find a vortex confinement transition from an integer vortex to a vortex molecule of $n$ $1/n$-quantized vortices, depending on the ratio between the term of the XY model and the modified term. We find for the case of $n=3$, a rod-shaped molecule is the most stable while a Y-shaped molecule is metastable. We also construct some solutions for the case of $n=4$.The vortex confinement transition can be understood in terms of the ${\mathbb C}/{\mathbb Z}_n$ orbifold geometry.

Algún quantifier is not bound by adverbs of quantification
Creators: name: Lopez-Carretero, Luis
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Some indefinites cannot be bound by adverbs of quantification or the generic operator. I argue that this datum follows from the internal syntax of indefinites: only those indefinites consisting of a minimal structure can be bound, bigger indefinites cannot. I present evidence from Spanish, Russian and English to support this claim. Two theoretical consequences follow. The first one is about wh-dependencies: I argue that wh-phrases cannot be regarded as noun phrases with an extra [wh] feature, but rather as very small indefinites without additional features. The second one involves exceptional scope: choice function approaches seem to run into a paradox that alternative approaches, such as Schwarszchild’s Singleton Indefinite approach, avoid. I also argue that an alternative semantic approach to binding resistance yields no fruit. Finally, I show that only small indefinites can be used as predicates, thus bolstering the approach taken in these pages.

description: The QCD light-front (LF) Hamiltonian equation H_{LF}|Ψ> = M^2 |Ψ> derived from quantization at fixed LF time τ= t+z/c provides a causal, frame-independent, method for computing hadron spectroscopy as well as dynamical observables such as structure functions, transverse momentum distributions, and distribution amplitudes. The LF formalism also leads to novel nuclear phenomena, such as "hidden color", "color transparency", "nuclear-bound quarkonium" and the shadowing and antishadowing of nuclear structure functions. For example, there are five distinct color-singlet Fock state representations of the six color-triplet quarks of the deuteron. The hidden color Fock states become manifest when the deuteron is probed when it has small transverse size, as in measurements of the deuteron form factor at large momentum transfer. The QCD Lagrangian with zero quark mass has no explicit mass scale. However, as shown by de Alfaro, Fubini, and Furlan (dAFF), a mass scale can appear in the equations of motion without affecting the conformal invariance of the Action. When one applies the dAFF procedure to the QCD LF Hamiltonian, it leads to a color confining potential κ^4 ζ^2 for mesons, where ζ^2 is the LF radial variable conjugate to the qbar-q invariant mass squared. The same result, including spin terms, is obtained using LF holography (AdS/QCD) -- the duality between LF dynamics and AdS_5 -- if one modifies the AdS_5 Action by the dilaton exp{+κ^2 z^2} in the fifth dimension z. If this procedure is generalized using superconformal algebra, the resulting LF eigensolutions provide unified Regge spectroscopy of mesons, baryons, and tetraquarks, including remarkable supersymmetric relations between the masses of mesons, baryons and tetraquarks with a universal Regge slope...

description: The effective linear and third-order nonlinear susceptibility of graded metallic films with weak nonlinearity have been investigated. Due to the simple geometry, we were able to derive exactly the local field inside the graded structures having a Drude dielectric gradation profile. We calculated the effective linear dielectric constant and third-order nonlinear susceptibility. We investigated the surface plasmon resonant effect on the optical absorption, optical nonlinearity enhancement, and figure of merit of graded metallic films. It is found that the presence of gradation in metallic films yields a broad resonant plasmon band in the optical region, resulting in a large enhancement of the optical nonlinearity and hence a large figure of merit. We suggest experiments be done to check our theoretical predictions, because graded metallic films can be fabricated more easily than graded particles.

description: We study a set of chiral symmetries contained in degenerate operators beyond the `minimal' sector of the c(p,q) models. For the operators h_{(2j+2)q-1,1}=h_{1,(2j+2)p-1} at conformal weight [ (j+1)p-1 ][ (j+1)q -1 ], for every 2j \in N, we find 2j+1 chiral operators which have quantum numbers of a spin j representation of SU(2). We give a free-field construction of these operators which makes this structure explicit and allows their OPEs to be calculated directly without any use of screening charges. The first non-trivial chiral field in this series, at j=1/2, is a fermionic or para-fermionic doublet. The three chiral bosonic fields, at j=1, generate a closed W-algebra and we calculate the vacuum character of these triplet models.

Detecting Gravitational Waves With Disparate Detector Responses: Two New Binary Black Hole Mergers

description: We introduce a new technique to search for gravitational wave events from compact binary mergers that produce a clear signal only in a single gravitational wave detector, and marginal signals in other detectors. Such a situation can arise when the detectors in a network have different sensitivities, or when sources have unfavorable sky locations or orientations. We start with a short list of loud single-detector triggers from regions of parameter space that are empirically unaffected by glitches (after applying signal-quality vetoes). For each of these triggers, we compute evidence for astrophysical origin from the rest of the detector network by coherently combining the likelihoods from all detectors and marginalizing over extrinsic geometric parameters. We report the discovery of two new binary black hole (BBH) mergers in the second observing run of Advanced LIGO and Virgo (O2), in addition to the ones that were reported in Abbott et al. (2018) and Venumadhav et al. (2019). We estimate that the two events have false alarm rates of one in 19 years (60 O2) and one in 11 years (36 O2). One of the events, GW170817A, has primary and secondary masses $m_1^{\rm src} = 56_{-10}^{+16} \, M_\odot$ and $m_2^{\rm src} = 40_{-11}^{+10} \, M_\odot$ in the source frame. The existence of GW170817A should be very informative about the theoretically predicted upper mass gap for stellar mass black holes. Its effective spin parameter is measured to be $χ_{\rm eff} = 0.5 \pm 0.2$, which is consistent with the tendency of the heavier detected BBH systems to have large and positive effective spin parameters. The other event, GWC170402, will be discussed thoroughly in future work.

Did Charles Bronston commit perjury? A study in discourse semantics
Creators: name: Lopez-Carretero, Luis
Publisher: name: University of Illinois at Chicago

Subjects: Uncategorized

description: In the landmark case Bronston v. US, the Supreme Court put forward a reading of the perjury statute according to which one could only be tried for perjury on the basis of what one had stated, not what was implicated. This decision has given rise to a number of theoretical and practical problems, best detailed in Tiersma (1990) and Douglis (2018). This article argues that a formal investigation of discourse structure, of the type developed in Asher and Lascarides (2003), coupled with an understanding of the role of ellipsis in discourse, allows us to develop a framework that captures those instances of perjury that seem to fall through the cracks of the literal truth condition without introducing speaker’s intent on the solution. The crucial idea that the analysis hinges on is the notion that an indirect answer to a question is a two-node discourse with an elliptical polarity answer. Approaches based on Grice’s implicatures or speaker’s communicative intent are discussed and shown to be inadequate.

description: The measurement of the invisible Z-boson decay width at e+e- colliders can be done "indirectly", by subtracting the Z-boson visible partial widths from the Z-boson total width, or "directly", from the process e+e- -> γν\barν. Both procedures are sensitive to different types of new physics and provide information about the couplings of the neutrinos to the Z-boson. At present, measurements at LEP and CHARM II are capable of constraining the left-handed Zνν-coupling, 0.45

Archival Records as Data Sets – Opportunities and Challenges of Digital Scholarship for University and Research Institution Archives

Subjects: digital scholarship
university archives

description: The emerging field of digital scholarship is a fascinating aspect of the digital transformation. Research and teaching based on and enabled by digital technologies do not only affect academia and researchers themselves, but also memory institutions. In many cases, it is libraries and archives that provide structured and unstructured, digitised and born digital data that is processed, edited, linked, evaluated or visualised within the framework of digital scholarship projects. The spectrum ranges from digital editions, computer-linguistic text enrichment and network analyses to the development of new scanning, transcription or text processing methods.
The paper argues that the field of digital scholarship has great potential, especially for university archives. At a strategic level, such projects are, not least of all, suitable for archives of technical universities as a means of positioning themselves as modern, innovative, flexible, technology- and research-oriented units. On a practical level, digital scholarship projects offer the opportunity to see an archive’s holdings and services from a perspective that is different from traditional research and uses.
Of course, research methods and tools of digital scholarships add to the complexity that archives face today. However, they have strong partners in this. Numerous international examples show how academic libraries are meeting this challenge successfully, utilising the latest technologies and creating new knowledge in partnership with researchers, scholars, and colleagues. Close collaboration between researchers, university archives and libraries is therefore a good way to increase expertise. Archives have far more to contribute to the development of 21st century research then scanned or born digital records. When archival material is increasingly seen and used as data, it is crucial to point out how important knowledge about provenance, context of origin or creation of evidence is and remains.
A dynamical mean-field study of orbital-selective Mott phase enhanced by next-nearest neighbor hopping

description: The dynamical mean-field theory is employed to study the orbital-selective Mott transition (OSMT) of the two-orbital Hubbard model with nearest neighbor hopping and next-nearest neighbor (NNN) hopping. The NNN hopping breaks the particle-hole symmetry at half filling and gives rise to an asymmetric density of states (DOS). Our calculations show that the broken symmetry of DOS benefits the OSMT, where the region of the orbital-selective Mott phase significantly extends with the increasing NNN hopping integral. We also find that Hund's rule coupling promotes OSMT by blocking the orbital fluctuations, but the influence of NNN hopping is more remarkable.

description: A watershed-based modeling system is developed to assess alternative nutrient abatement policies, including fertilizer taxes, application caps, and uniform reductions. A microeconometric model of nutrient use is estimated using farm-level data, prices, and spatially detailed soil and land characteristics. Results are interfaced with a physical watershed model to predict water quality changes. Simulations demonstrate differences in water quality effects across policies. For nitrate loads at the watershed outlet, an application cap provides slightly superior performance for small reductions, but a tax is more efficient under larger reductions. Phosphorus reductions at the subwatershed level vary but provide information about policy tradeoffs.

description: Modern technology civilization, yet rapidly growing dependence on the world, ends with increased demand for energy consumption. An increasing aim of creating a sustainable environment involves the careful use of energy sources. The use of renewable energy resources to improve the performance of current technology and thus economically proper use of energy are three important strategies in addressing those concerns. Geothermal energy is a renewable source of energy with the ability to generate a fair amount of the world's natural hot electricity, heating, and cooling. In all volcanoes, geysers, and the low enthalpy types, it occurs in high enthalpy where the warmth in the crust is contained in rocks. The current research explores the direct use of energy through the ORC method worldwide and the future planning of these prospects for renewable sources of energy. Different nations use heat energy directly in many ways and discuss in particular the generation of electricity over the last twenty years and their future projects. In addition, technology's environmental impact and economic viability are mapped. Recent studies support the advantages and limitations of technology and opportunities for improvement. Briefly, the study discusses the potential role of geothermal technology in an extremely sustainable future. Finally, for further investigation, the likely subjects of future research will be presented.

description: RF plasma assisted MBE growth of Scandium Nitride (ScN) thin films on GaN (0001)/SiC, AlN (0001)/Al2O3 and on 6H-SiC (0001) hexagonal substrates is found to lead to a face centered cubic (rock-salt) crystal structure with (111) out-of-plane orientation instead of hexagonal orientation. For the first time, cubic (111) twinned patterns in ScN are observed by in-situ electron diffraction during epitaxy, and the twin domains in ScN are detected by electron backscattered diffraction, and further corroborated with X-ray diffraction. The epitaxial ScN films display very smooth, sub nanometer surface roughness at a growth temperature of 750C. Temperature-dependent Hall-effect measurements indicate a constant high n-type carrier concentration of ~1x1020/cm3 and electron mobilities of ~ 20 cm2/Vs.

description: We report squeezed polariton generation using parametric polariton four-wave mixing in semiconductor microcavities in the strong coupling regime. The geometry of the experiment corresponds to degenerate four-wave mixing, which gives rise to a bistability threshold. Spatial effects in the nonlinear regime are evidenced, and spatial filtering is required in order to optimize the measured squeezing. By measuring the noise of the outgoing light, we infer a 9 percent squeezing on the polariton field close to the bistability turning point.
