description: We describe an implementation of Hedin's GW approximation for molecules and clusters, the complexity of which scales as O(N^3) with the number of atoms. Our method is guided by two strategies: i) to respect the locality of the underlying electronic interactions and ii) to avoid the singularities of Green's functions by manipulating, instead, their spectral functions using FFT methods. To take into account the locality of the electronic interactions, we use a local basis of atomic orbitals and, also, a local basis in the space of their products. We further compress the screened Coulomb interaction into a space of lower dimensions for speed and to reduce memory requirements. The improved scaling of our method with respect to most of the published methodologies should facilitate GW calculations for large systems. Our implementation is intended as a step forward towards the goal of predicting, prior to their synthesis, the ionization energies and electron affinities of the large molecules that serve as constituents of organic semiconductors.

title:   QUALITY CONTROL METHODS THROUGH PRE-DETERMINATION OF FIELDS FOR usRAP PROJECTS
Creators: name: Heath, Zachary
Publisher: name: University of Kentucky Libraries
Year: 2023
Subjects: classificationCode: 2.1
subject: FOS: Civil engineering

description: The United States Road Assessment Program (usRAP) was designed to rate highways for their ability to protect road users and to make recommendations to engineers and policy makers for investments to enhance road safety. The program is heavily dependent on local road data or characteristics. Pre-populating usRAP requires coders to evaluate sixty-six attributes at 100-meter intervals along a subject highway. In this thesis, methods for obtaining and assuring the quality of some of the usRAP data elements are proposed. Kentucky Transportation Cabinet Highway Information System (HIS) data are used as “ground truth” for roadway grade and curvature. Methods of using light detection and ranging (LiDAR) are explored to either establish or assure the quality of data for roadside severities including cliffs, aggressive vertical faces, upward slopes (15-75 degrees), deep drainage ditches, downward slopes (>-15 degrees), and upward slopes (>=75 degrees) by developing digital cross sections. Methods to use LiDAR to determine roadway grade, curvature, and roadside slope are also explored. These methods are evaluated for feasibility using standard surveying and GIS software. Results indicate that roadway grade and curvature are difficult to estimate using only imagery and LiDAR may be used to measure grade and cross slope only if resolution is adequate. Other methods are proposed for future research and application.

description: A model based on the interfacial compatibility of plastic deformations is formulated to predict the patterns of grain fragmentation at different strain values and different grain orientations. The model imposes a macroscopic deformation on the skeleton of grain boundaries, which, in turn, prescribes a certain General projection of plastic deformations on both sides of any boundary face. In order to accommodate 3 independent components of this projection, each boundary plane is deformed by three sliding systems. In contrast to the Taylor model, such sliding models on different faces of the same grain are different and, therefore, cause splitting of the crystal orientation near the interface of the boundary planes.
Investigating molecular clustering of Rv1747 in M. smegmatis

Publisher: name: University of British Columbia

description: Phase separation is involved in the organization and regulation of membraneless cellular components and their functions. We showed previously that the cytoplasmic regulatory module of the ABC transporter Rv1747 of Mycobacterium tuberculosis, which is involved in cell wall biosynthesis, is able to phase separate in vitro. Here we demonstrate that this regulatory module forms static foci and full length Rv1747 mobile ones dependent on the presence of the regulatory module in Mycobacterium smegmatis. Disrupting the key interactions by the FHA domains in this regulatory module, in particular FHA-1, and phosphorylated threonines in the linker between the FHA domains demolish the resulting foci in both constructs. Specifically, we show that the S47A single mutant and the S47A, S248A double mutant exhibit no foci formation while the S248A single mutant exhibits a mixed phenotype dominated by diminished clustering. Complementarily, the regulatory module of Rv1747 carrying phosphor-ablative mutations of all Thr/Ser to Ala in the linker also shows no sign of foci formation. In addition, charges of the intrinsically disordered linker also contribute to foci formation by the Rv1747 regulatory module, as the mutant carrying Arg/Lys to Ala mutations displays no foci in M. smegmatis. Collectively, these data strongly suggest that Rv1747 phase separates in M. smegmatis and highlight the role of phosphorylation and non-specific charge-charge interactions by the FHA domains and the ID linker in regulating phase separation of Rv1747 in M. smegmatis.

description: Less than 3% of the known exoplanets were directly imaged for two main reasons. They are angularly very close to their parent star, which is several magnitudes brighter. Direct imaging of exoplanets thus requires a dedicated instrumentation with large telescopes and accurate wavefront control devices for high-angular resolution and coronagraphs for attenuating the stellar light. Coronagraphs are usually chromatic and they cannot perform high-contrast imaging over a wide spectral bandwidth. That chromaticity will be critical for future instruments. Enlarging the coronagraph spectral range is a challenge for future exoplanet imaging instruments on both space-based and ground-based telescopes. We propose the multi-stage four-quadrant phase mask that associates several monochromatic four-quadrant phase mask coronagraphs in series. Monochromatic device performance has already been demonstrated and the manufacturing procedures are well-under control since their development for previous instruments on VLT and JWST. The multi-stage implementation simplicity is thus appealing. We present the instrument principle and we describe the laboratory performance for large spectral bandwidths and for both pupil shapes for space- (off-axis telescope) and ground-based (E-ELT) telescopes. The multi-stage four-quadrant phase mask reduces the stellar flux over a wide spectral range (30%) and it is a very good candidate to be associated with a spectrometer for future exoplanet imaging instruments in ground- and space-based observatories.

description: NOI, RAGAZZI E RAGAZZE, CHE DIRITTI ABBIAMO? Tutti i ragazzi/e al di sotto dei 18 anni sono minorenni, cioè minori quanto all’età (così dispone l’art.2 Codice civile). Le persone di età minore, infatti, non hanno ancora raggiunto la capacità di agire, che è la capacità di compiere atti giuridici validi, per esempio comprare da sola/o un telefonino o firmare il consenso informato per un intervento chirurgico. Fanno eccezione gli atti che la legge espressamente consente alla persona minorenne di compiere. Per esempio, le studentesse e gli studenti della scuola secondaria superiore esercitano personalmente all'atto dell'iscrizione, il diritto di scegliere se avvalersi o non avvalersi dell'insegnamento della religione cattolica (art. 310 comma 4° Decreto Legislativo 16 aprile 1994, n. 297). Inoltre, i/le minorenni ultra14enni hanno il diritto di esprimere in autonomia il loro consenso al trattamento dei dati personali che li riguardino allorquando vi sia un’offerta diretta dei servizi della società dell’informazione: il cosiddetto “consenso digitale” ai social media: (vd. art. 8 Regolamento UE 2016/679, in sigla GDPR; art. 2quinquies Decreto legislativo 30 giugno 2003, n.196). Il fatto che, in generale, i minorenni non possano esercitare dirittamente i loro diritti non significa tuttavia che non li abbiano. I minorenni, infatti, godono degli stessi diritti che spettano ad ogni altro essere umano, per esempio il diritto al rispetto della vita privata e familiare. Ma non solo! Hanno diritti specifici che vengono loro riconosciuti proprio in quanto persone di età minore, perché vivono in una condizione di vulnerabilità da cui deriva un bisogno di protezione speciale, più ‘forte’ rispetto a quella garantita agli adulti. continua a leggere...

description: That static electric and magnetic fields can store momentum may be perplexing, but is necessary to ensure total conservation of momentum. Simple situations in which such field momentum is transferred to nearby bodies and point charges have often been considered for pedagogical purposes, normally assuming vacuum surroundings. If dielectric media are involved, however, the analysis becomes more delicate, not least since one encounters the electromagnetic energy-momentum problem in matter, the `Abraham-Minkowski enigma', of what the momentum is of a photon in matter. We analyze the momentum balance in three nontrivial examples obeying azimuthal symmetry, showing how the momentum conservation is satisfied as the magnetic field decays and momentum is transferred to bodies present. In the last of the examples, that of point charge outside a dielectric sphere in an infinite magnetic field, we find that not all of the field momentum is transferred to the nearby bodies; a part of the momentum appears to vanish as momentum flux towards infinity. We discuss this and other surprising observations which can be attributed to the assumption of magnetic fields of infinite extent. We emphasize how formal arguments of conserved quantities cannot determine which energy-momentum tensor is more "correct", and each of our conservation checks may be performed equally well in the Minkowski or Abraham framework.

Environmental variability and geomorphic responses on alluvial fans : an experimental study
Creators: name: Leenman, Anya S.
Publisher: name: University of British Columbia
Year: 2021

description: The dynamic behaviour of channels on alluvial fans can present hazards to infrastructure and human lives. In particular, avulsion, lateral channel migration, and erosion and deposition of sediment can present problems. Much of our understanding of these dynamics comes from small-scale physical experiments with constant flow and sediment supply. Recent research suggests that constant inputs to steep streams on fans do a poor job of representing the temporally varying inputs to natural streams. This dissertation presents a suite of physical alluvial fan experiments which further explore the impacts of temporally varying inputs. First, an experiment with constant inputs shows that complex, unpredictable avulsion dynamics can arise in simple conditions due to in-channel sedimentation, particularly around large grains. Second, a set of experiments with temporally varying flow demonstrates that flood hydrograph shape governs the geomorphic impact of floods on fans; non-linear relations between the instantaneous flow and the magnitude of geomorphic change mean that more material was moved by short, high-peaked floods than by long, low-peaked floods. Third, experiments with temporally varying sediment feed show that rapid erosion and channel adjustment can be triggered by both increases and decreases in the feed rate. Moreover, longer-duration feed variations generate lower-gradient, elongate fans with a more incised fan-head trench. Together, these experiments highlight the distortions introduced when temporally varying inputs are replaced with constant flow or sediment feed. In addition, the experiments are significant for understanding hazards on fans, as they indicate how fan morphology and channel dynamics might vary as climate change alters the frequency and severity of high flows and sediment inputs in mountain streams.

description: In this paper, we investigate experimentally the non-equilibrium steady state of an active colloidal suspension under gravity field. The active particles are made of chemically powered colloids, showing self propulsion in the presence of an added fuel, here hydrogen peroxide. The active suspension is studied in a dedicated microfluidic device, made of permeable gel microstructures. Both the microdynamics of individual colloids and the global stationary state of the suspension under gravity - density profiles, number fluctuations - are measured with optical microscopy. This allows to connect the sedimentation length to the individual self-propelled dynamics, suggesting that in the present dilute regime the active colloids behave as 'hot' particles. Our work is a first step in the experimental exploration of the out-of-equilibrium properties of artificial active systems.

description: Loosely speaking, a semi-frame is a generalized frame for which one of the frame bounds is absent. More precisely, given a total sequence in a Hilbert space, we speak of an upper (resp. lower) semi-frame if only the upper (resp. lower) frame bound is valid. Equivalently, for an upper semi-frame, the frame operator is bounded, but has an unbounded inverse, whereas a lower semi-frame has an unbounded frame operator, with bounded inverse. We study mostly upper semi-frames, both in the continuous case and in the discrete case, and give some remarks for the dual situation. In particular, we show that reconstruction is still possible in certain cases.

description: We present an analysis of 15 Chandra observations of the nearby spiral galaxy M81 taken over the course of six weeks in May--July 2005. Each observation reaches a sensitivity of ~10^37 erg/s. With these observations and one previous deeper Chandra observation, we compile a master source list of 265 point sources, extract and fit their spectra, and differentiate basic populations of sources through their colors. We also carry out variability analyses of individual point sources and of X-ray luminosity functions in multiple regions of M81 on timescales of days, months, and years. We find that, despite measuring significant variability in a considerable fraction of sources, snapshot observations provide a consistent determination of the X-ray luminosity function of M81. We also fit the X-ray luminosity functions for multiple regions of M81 and, using common parametrizations, compare these luminosity functions to those of two other spiral galaxies, M31 and the Milky Way.

description: We present the final results of the Apodized Pupil Lyot Coronagraph (APLC) on the High-contrast imager for Complex Aperture Telescopes (HiCAT) testbed, under NASA's Strategic Astrophysics Technology program. The HiCAT testbed was developed over the past decade to enable a system-level demonstration of coronagraphy for exoplanet direct imaging with the future Habitable Wolds Observatory. HiCAT includes an active, segmented telescope simulator, a coronagraph, and metrology systems (Low-order and Mid-Order Zernike Wavefront Sensors, and Phase Retrieval camera). These results correspond to an off-axis (un-obscured) configuration, as was envisioned in the 2020 Decadal Survey Recommendations. Narrowband and broadband dark holes are generated using two continuous deformable mirrors (DM) to control high order wavefront aberrations, and low-order drifts can be further stabilized using the LOWFS loop. The APLC apodizers, manufactured using carbon nanotubes, were optimized for broadband performance and include the calibrated geometric aperture.
 HiCAT is, to this date, the only testbed facility able to demonstrate high-contrast coronagraphy with a truly segmented aperture, as is required for the Habitable World Observatory, albeit limited to ambient conditions. Results presented here include $6\times 10^{-8}$ (90% CI) contrast in 9% bandpass in a 360 deg dark hole with inner and outer working angles of $4.4 λ/D_{pupil}$ and $11 λ/D_{pupil}$ . Narrowband contrast (3% bandpass) reaches $2.4\times 10^{-8}$ (90% confidence interval).

description: We study theoretically dynamic response of a mesoscopic capacitor, which consists of a quantum dot connected to an electron reservoir via a point contact and capacitively coupled to a gate voltage. A quantum Hall edge state with a filling factor nu is realized in a strong magnetic field applied perpendicular to the two-dimensional electron gas. We discuss a noise-driven quantum phase transition of the transport property of the edge state by taking into account an ohmic bath connected to the gate voltage. Without the noise, the charge relaxation for nu>1/2 is universally quantized at R_q=h/(2e^2), while for nu<1/2, the system undergoes the Kosterlitz-Thouless transtion, which drastically changes the nature of the dynamical resistance. The phase transition is facilitated by the noisy gate voltage, and we see that it can occur even for an integer quantum Hall edge at nu=1. When the dissipation by the noise is sufficiently small, the quantized value of R_q is shifted by the bath impedance.

description: Even 100 years after the discovery of cosmic rays their origin remains a mystery. In recent years, TeV gamma-ray detectors have discovered and investigated many Galactic sources where particles are accelerated up to energies of 100 TeV. However, it has not been possible up to now to identify these sites unambiguously as sources of hadronic acceleration. The observation of cosmic high-energy neutrinos from these or other sources will be a smoking-gun evidence for the sites of the acceleration of cosmic rays.

description: Cosmological constraints from cluster surveys rely on accurate mass estimates from the mass-observable relations. In order to avoid systematic biases and reduce uncertainties, we study the form and physical origin of the intrinsic scatter about the mean Sunyaev-Zel'dovich (SZ) flux-mass relation using a hydrodynamical simulation of galaxy cluster formation. We examine the assumption of lognormal scatter and detect non-negligible positive skewness and kurtosis (> 0.5) for a wide range of limiting masses and redshifts. These higher-order moments should be included in the parametrization of scatter in order not to bias cosmological constraints. We investigate the sources of the scatter by correlating it with measures of cluster morphology, halo concentration, and dynamical state, and we quantify the individual contribution from each source. We find that statistically the impact of dynamical state is weak, so the selection bias due to mergers is negligible. On the other hand, there is a strong correlation between the scatter and halo concentration, which can be used to reduce the scatter significantly (from 12.07% to 7.34% or by ~40% for clusters at z = 0). We also show that a cross-calibration by combining information from X-ray followups can be used to reduce the scatter in the flux-mass relation and also identify outliers in both X-ray and SZ cluster surveys.

description: In this article we examine the role of Entscheider (decision-makers) in the German asylum procedure, both legally and ethical. As the responsibility for deciding on asylum applications lies exclusively with them, their significance for the German asylum procedure can hardly be underestimated. However, over the last few decades the situation of Entscheider changed significantly: While the number and complexity of the cases they have to decide on has increased due to the growing immigration, the requirements for their education have been lowered, owed to critical amendments to the relevant law. We analyze how the law currently defines the role of Entscheider, whether the legal framework is constitutional, and what modifications morality requires. Although the law defining their role seems to be constitutional, Entscheider’s education must be improved and they must be entrusted with the hearing of the applicants to meet what morality requires, we conclude.
On sustainability and financial return of fishery resources

description: Overexploitation and resource rent dissipation are some of the fundamental issues in fisheries management. The first undermines food security while the second implies a minimal economic return to the owning society. Sustainable fisheries are predominantly attained in conjunction with high management intensity, which keeps exploitation rates in check. Yet controlling exploitation becomes a daunting task under many complex fisheries contexts. Further, although profitability of fishing industry has improved after introducing quota-based systems, it is perceived that society is not receiving a fair share of the resource rent. In this dissertation, I focus on the Arabian Gulf region as a microcosm to examine various complex fisheries problems and underline, globally, the society’s compensation from the fishing industry. I begin by discussing situations where open access conditions are irreversible due to inherently poor management institutions or high dependency on fishing for livelihood. I show that well-designed size restriction—an easily implementable approach—can help avert overexploitation, rebuild depleted fish stocks and enhance yields without controlling exploitation rates. Next, I examine internationally shared fish stocks, whose sustainability requires managing exploitation rates at the international level rather than merely locally. I develop an age-structured model to evaluate bioeconomic trade-offs under alternative fishing scenarios. Harvesting a shared fish stock under cooperation or local but sustainable management provides much higher bioeconomic gains than competition. I then discuss the impacts of escalated market demand for dried swim bladder on fish, people and management in source countries. I highlight that while management interventions are required, the extremely high value of swim bladder would complicate regulatory efforts by stimulating black-market systems. Finally, I examine whether resource rent charges are imposed on catch share fisheries, and systematically compare that with forestry, oil, gas, and mining in 18 countries. I show that fishing is the only industry that consistently lacks resource rent charges, implying a forgoing stream of income in most countries. My dissertation contributes toward alleviating overfishing when exploitation rates are difficult to manage and underscores the need for national policies to consider the enhanced profitability of the fishing industry under catch share systems.

description: Let $X$ be a Hausdorff topological vector space, $X^*$ its topological dual and $Z$ a subset of $X^*$. In this paper, we establish some results concerning the $σ(X,Z)$-approximate fixed point property for bounded, closed convex subsets $C$ of $X$. Three major situations are studied. First when $Z$ is separable in the strong topology. Second when $X$ is a metrizable locally convex space and $Z=X^*$, and third when $X$ is not necessarily metrizable but admits a metrizable locally convex topology compatible with the duality. Our approach focuses on establishing the Fréchet-Urysohn property for certain sets with regarding the $σ(X,Z)$-topology. The support tools include the Brouwer's fixed point theorem and an analogous version of the classical Rosenthal's $\ell_1$-theorem for $\ell_1$-sequences in metrizable case. The results are novel and generalize previous work obtained by the authors in Banach spaces.

description: The Pd/InP structures at the temperature range 90-300K in vacuum and in hydrogen atmosphere have been investigated. The basic current transition parameters have been determined. There was found two conduction mechanisms â tunneling and thermal-tunneling. The electric characteristic changing of the structures under hydrogen exposure is demonstrated. It was shown that under hydrogen exposure the current conduction mechanism in the structures shifts towards termal-tunneling mechanism. The investigation of current conduction mechanisms based on thermionic emission is demonstrated.

description: The search for physics beyond the Standard Model (BSM) is one of the most important goals for the general purpose detector ATLAS at the Large Hadron Collider at CERN. Supersymmetry search strategies based on generic event signatures of high jet multiplicity and large missing transverse momentum, optionally including leptons in the final state with R-parity conservation are discussed in this document. We review the results for above SUSY search strategies with first data up to 305 $nb^{-1}$ of integrated luminosity collected by ATLAS during 2010 at a centre-of-mass energy of 7 TeV.

Self-repairing in single-walled carbon nanotubes by heat treatment

description: Structure transformation by heat treatment in single-walled carbon nanotubes (SWCNT) is investigated using molecular dynamics simulation. The critical temperature for the collapse of pure SWCNT is as high as 4655 K due to strong covalent carbon-carbon bonding. Above 2000 K, the cross section of SWCNT changes from circle to ellipse. The self-repairing capability is then investigated and two efficient processes are observed for the SWCNT to repair themselves. (1) In the first mechanism, vacancy defects aggregate to form a bigger hole, and a bottleneck junction is constructed nearby. (2) In the second mechanism, a local curvature is generated around the isolate vacancy to smooth the SWCNT. Benefit from the powerful self-repairing capability, defective SWCNT can seek a stable configuration at high temperatures; thus the critical temperature for collapse is insensitive to the vacancy defect density.

description: We study the screening of the Coulomb interaction in a quasi one-dimensional superconductor given by the presence of either a one- or a two-dimensional non-interacting electron gas. To that end, we derive an effective low-energy phase-only action, which amounts to treating the Coulomb and superconducting correlations in the random-phase approximation. We concentrate on the study of dissipation effects in the superconductor, induced by the effect of Coulomb coupling to the diffusive density-modes in the metal, and study its consequences on the static and dynamic conductivity. Our results point towards the importance of the dimensionality of the screening metal in the behavior of the superconducting plasma mode of the wire at low energies. In absence of topological defects, and when the screening is given by a one-dimensional electron gas, the superconducting plasma mode is completely damped in the limit $q\to 0$, and consequently superconductivity is lost in the wire. In contrast, we recover a Drude-response in the conductivity when the screening is provided by a two-dimensional electron gas.

description: Background:
Dysphagia, or swallowing disorders, represents a significant health concern as it can lead to severe health events such as aspiration pneumonia, choking, and malnutrition. With the global increase in the aging population, reports of dysphagia have emerged not only in common causative conditions like stroke but also in a range of other disorders. Notably, an increasing number of cases have been documented where patients with heart failure develop dysphagia following hospitalization. Understanding the prevalence and implications of dysphagia in individuals with heart failure is believed to contribute to the advance swallowing rehabilitation practices.Objective and Review Questions:
The purpose of this scoping review is to identify the prevalence of dysphagia in hospitalized heart failure patients and to identify its related factors. The research question for this review is “What is the prevalence of dysphagia and its related factors in heart failure patients?”

description: Quantum theory may be formulated using Hilbert spaces over any of the three associative normed division algebras: the real numbers, the complex numbers and the quaternions. Indeed, these three choices appear naturally in a number of axiomatic approaches. However, there are internal problems with real or quaternionic quantum theory. Here we argue that these problems can be resolved if we treat real, complex and quaternionic quantum theory as part of a unified structure. Dyson called this structure the "three-fold way". It is perhaps easiest to see it in the study of irreducible unitary representations of groups on complex Hilbert spaces. These representations come in three kinds: those that are not isomorphic to their own dual (the truly "complex" representations), those that are self-dual thanks to a symmetric bilinear pairing (which are "real", in that they are the complexifications of representations on real Hilbert spaces), and those that are self-dual thanks to an antisymmetric bilinear pairing (which are "quaternionic", in that they are the underlying complex representations of representations on quaternionic Hilbert spaces). This three-fold classification sheds light on the physics of time reversal symmetry, and it already plays an important role in particle physics. More generally, Hilbert spaces of any one of the three kinds - real, complex and quaternionic - can be seen as Hilbert spaces of the other kinds, equipped with extra structure.
