description: Thin films of $α$-MoGe show progressively reduced $T_{c}$'s as the thickness is decreased below 30 nm and the sheet resistance exceeds 100 $Ω/\Box$. We have performed far-infrared transmission and reflection measurements for a set of $α$-MoGe films to characterize this weakened superconducting state. Our results show the presence of an energy gap with ratio $2Δ_0/k_BT_{c} = 3.8 \pm 0.1$ in all films studied, slightly higher than the BCS value, even though the transition temperatures decrease significantly as film thickness is reduced. The material properties follow BCS-Eliashberg theory with a large residual scattering rate except that the coherence peak seen in the optical scattering rate is found to be strongly smeared out in the thinner superconducting samples. A peak in the optical mass renormalization at $2Δ_0$ is predicted and observed for the first time.

description: In this paper, we study the nonlinear Schrödinger equation with focusing point nonlinearity in dimension one. First, we establish a scattering criterion for the equation based on Kenig-Merle's compactness-rigidity argument. Then we prove the energy scattering below and above the mass-energy threshold. We also describe the dynamics of solutions with data at the ground state threshold. Finally, we prove a blow-up criteria for the equation with initial data with arbitrarily large energy.

description: The dominant source of decoherence for an electron spin in a quantum dot is the hyperfine interaction with the surrounding bath of nuclear spins. The decoherence process may be slowed down by subjecting the electron spin to suitable sequences of external control pulses. We investigate the performance of a variety of dynamical decoupling protocols using exact numerical simulation. Emphasis is given to realistic pulse delays and the long-time limit, beyond the domain where available analytical approaches are guaranteed to work. Our results show that both deterministic and randomized protocols are capable to significantly prolong the electron coherence time, even when using control pulse separations substantially larger than what expected from the {\em upper cutoff} frequency of the coupling spectrum between the electron and the nuclear spins. In a realistic parameter range, the {\em total width} of such a coupling spectrum appears to be the physically relevant frequency scale affecting the overall quality of the decoupling.

Three-Dimensional Dynamical Instabilities in Galactic Ionization Fronts
Creators: name: Whalen, Daniel J.
name: Norman, Michael L.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Ionization front instabilities have long been of interest for their suspected role in a variety of phenomena in the galaxy, from the formation of bright rims and 'elephant trunks' in nebulae to triggered star formation in molecular clouds. Numerical treatments of these instabilities have historically been limited in both dimensionality and input physics, leaving important questions about their true evolution unanswered. We present the first three-dimensional radiation hydrodynamical calculations of both R-type and D-type ionization front instabilities in galactic environments (i.e., solar metallicity gas). Consistent with linear stability analyses of planar D-type fronts, our models exhibit many short-wavelength perturbations growing at early times that later evolve into fewer large-wavelength structures. The simulations demonstrate that both self-consistent radiative transfer and three-dimensional flow introduce significant morphological differences to unstable modes when compared to earlier two-dimensional approximate models. We find that the amplitude of the instabilities in the nonlinear regime is primarily determined by the efficiency of cooling within the shocked neutral shell. Strong radiative cooling leads to long, extended structures with pronounced clumping while weaker cooling leads to saturated modes that devolve into turbulent flows. These results suggest that expanding H II regions may either promote or provide turbulent support against the formation of later generations of stars, with potential consequences for star formation rates in the galaxy today.

Distribution of gold in soils and stream sediments and the use of cyanidation in exploration geochemistry
Creators: name: Delaney, Tracy Anne
Publisher: name: University of British Columbia
Year: 2008

description: Obtaining samples that are both representative and small enough to be analyzed efficiently by standard analytical techniques is a common problem in gold exploration. The recent use of cyanide to extract gold from geochemical samples has allowed samples up to 1 kg or larger to be processed. Results of cyanide analyses cannot be interpreted, however, without first understanding the mode of occurrence of gold in the sample media. Therefore, the location of gold in soils and stream sediments over a variety of deposits in different weathering regimes was determined prior to examining the efficiency of cyanidation. Soil samples were collected over gold mineralization in Nevada, Utah and the Yukon Territory, and over tills covering gold deposits in British Columbia and Ontario. Except in Ontario, stream sediments were also collected. After wet sieving into four fractions between 2000 μm (10 mesh, ASTM) and 53 μm (270 mesh, ASTM) and separation of heavy minerals (S.G. 3.3), samples were analyzed for gold by fire assay-atomic absorption spectroscopy (FA-AAS) and cyanide-AAS (CN-AAS). Results indicate that, on average, 70% of the gold in soils and 67% of the gold in stream sediments resides in the finest fraction (-53 μm, -270 ASTM). Furthermore, although gold concentrations are highest in the heavy mineral fractions (HMCs), the percentage of gold is generally higher in the light mineral fractions (LMFs) and -53 μm fractions, particularly in samples from Nevada and the Yukon Territory. Comparison of CN-AAS analyses with those by FA-AAS -- assumed to represent total gold concentrations -- indicate that, on average, 60% of the gold in soils and about 40% of gold in stream sediments was accessible by cyanide solutions. In regard to exploration, a representative 30 g subsample can generally be obtained from wet sieving of a 500 g field sample. Although the -53 μm fraction contains the bulk of the gold -- and the least possibility of erratic values resulting from the nugget effect -- representativity is not greatly reduced in the -212 μm fraction. There appears to be no particular advantage to preparation of HMCs because gold concentrations can generally be detected in combined density fractions. Cyanidation was effective in detecting gold in all six areas. However, there is no advantage in using this analytical method in areas of fine particulate gold where gold concentrations are easily detected using FA-AAS. Cyanidation may be more useful in areas of low gold concentrations where large (i.e. > 100 g) subsamples are required to obtain representativity, or where gold exists in a variety of particle sizes. Sieving to a size fraction below 212 μm is recommended, however, to optimize representativity.

description: Grice's Cooperative Principle (1975) describes the implicit maxims that guide conversation between humans. As humans begin to interact with non-human dialogue systems more frequently and in a broader scope, an important question emerges: what principles govern those interactions? The present study addresses this question by evaluating human-AI interactions using Grice's four maxims; we demonstrate that humans do, indeed, apply these maxims to interactions with AI, even making explicit references to the AI's performance through a Gricean lens. Twenty-three participants interacted with an American English-speaking Alexa and rated and discussed their experience with an in-lab researcher. Researchers then reviewed each exchange, identifying those that might relate to Grice's maxims: Quantity, Quality, Manner, and Relevance. Many instances of explicit user frustration stemmed from violations of Grice's maxims. Quantity violations were noted for too little but not too much information, while Quality violations were rare, indicating trust in Alexa's responses. Manner violations focused on speed and humanness. Relevance violations were the most frequent, and they appear to be the most frustrating. While the maxims help describe many of the issues participants encountered, other issues do not fit neatly into Grice's framework. Participants were particularly averse to Alexa initiating exchanges or making unsolicited suggestions. To address this gap, we propose the addition of human Priority to describe human-AI interaction. Humans and AIs are not conversational equals, and human initiative takes priority. We suggest that the application of Grice's Cooperative Principles to human-AI interactions is beneficial both from an AI development perspective and as a tool for describing an emerging form of interaction.

They are described by calibrated surfaces that end on the boundary of anti de-Sitter space and are pseudo-holomorphic with respect to an almost complex structure on an eight-dimensional slice of AdS_5 x S^5. The regularized area of these surfaces vanishes, in agreement with field theory non-renormalization theorems for the corresponding operators.

description: Cyclopropenone was first detected in the cold and less dense envelope of Sagittarius B2(N). It was found later in several cold dark clouds and it may be possible to detect its minor isotopic species in these environments. In addition, the main species may well be identified in warmer environments. We aim to extend existing line lists of isotopologs of c-H2C3O from the microwave to the millimeter region and create one for the singly deuterated isotopolog to facilitate their detections in space. Furthermore, we aim to extend the line list of the main isotopic species to the submillimeter region and to evaluate an equilibrium structure of the molecule. We employed a cyclopropenone sample in natural isotopic composition to investigate the rotational spectra of the main and 18O-containing isotopologs as well as the two isotopomers containing one 13C atom. Spectral recordings of the singly and doubly deuterated isotopic species were obtained using a cyclopropenone sample highly enriched in deuterium. We recorded rotational transitions in the 70-126 GHz and 160-245 GHz regions for all isotopologs and also in the 342-505 GHz range for the main species. Quantum-chemical calculations were carried out to evaluate initial spectroscopic parameters and the differences between ground-state and equilibrium rotational parameters in order to derive semi-empirical equilibrium structural parameters. We determined new or improved spectroscopic parameters for six isotopologs and structural parameters according to different structure models. The spectroscopic parameters are accurate enough to identify minor isotopic species at centimeter and millimeter wavelengths while those of the main species are deemed to be reliable up to 1 THz. Our structural parameters differ from earlier ones. The deviations are attributed to misassignments in the earlier spectrum of one isotopic species.

description: España es un país dominado mayoritariamente por un clima de tipo mediterráneo, donde los veranos secos anuales se alternan con períodos largos ocasionales de sequía pluviométrica. Esta irregularidad en el régimen de precipitaciones ha generado graves problemas socioeconómicos a lo largo de la historia, debido al peso que el sector agrario ha tenido, y tiene, en muchas regiones del país. Aquí se presentan algunas maneras con las que el sector agrario se ha ido adaptando a esta limitación ambiental a diferentes escalas (gobierno, región y finca), en particular en la segunda mitad del siglo XX, gracias a los avances tecnológicos. Ejemplos de la planificación gubernamental de conversión de tierras en regadío en base a construcción de embalses o canales, adaptaciones a escala regional de tierras agrícolas, o construcción de infraestructuras clave a nivel de finca para mejorar la productividad de las mismas, son algunos de los casos paradigmáticos aquí tratados.

In addition to the usual renormalization conditions one needs to incorporate new ones in order to remove non-transverse UV divergences in the truncated two- and four-photon functions. The corresponding counterterms are allowed by gauge symmetry, in-medium independent and suppressed with respect to the accuracy of the truncation.

We discuss, in particular, the implementation of pulsar timing analysis, which was recently upgraded in PEP to handle more options. This implementation was done independently of other pulsar programs, with minor exceptions that we discuss. We illustrate the implementation of this capability by comparing the post-fit residuals from the analyses of time-of-arrival observations by both PEP and Tempo2. The comparison shows substantial agreement: 22 ns rms differences for 1,065 pulse time-of-arrival measurements for the millisecond pulsar in a binary system, PSR J1909-3744 (pulse period 2.947108 ms; full-width half-maximum of pulse 43 $μ$s) for epochs in the interval from December 2002 to February 2011.

description: Aim of this study was to determine ascorbic acid (AA) levels in plasma and white blood cells (WBC) in subjects with MDS, and to investigate possible correlation between AA levels / response upon AA supplementation and MDS features. This could help in clarifying the pathogenesis of MDS and establish a role for AA as a functional and reliable prognostic factor in the treatment and follow-up of subjects with MDS. MDS are a heterogeneous group of haematologic malignancies. The basic defect is a clonal mutation of the stem cell which leads to the evolution of a pathologic clone. The main features of MDS are ineffective haematopoiesis and peripheral cytopenia, although the bone marrow is mostly hypercellular. This is probably mediated through a significant increase of programmed cell death (apoptosis) of blood cells.We studied 50 patients with MDS and 20 control subjects. By means of highperformance liquid chromatography (HPLC) we assayed in plasma and WBC cells(granulocytes and mononuclear) ascorbic acid, total ascorbic acid and percentage of dehydroascorbic acid (DHA) upon total ascorbic acid. Moreover, to study the effect of AA upon a stem cell population, we performed bone marrow cultures in ten patients with MDS and two control subjects. Cultures were supplemented with 0 (control culture), 25 and 50 μΜ ascorbic acid solutions (similar to those observed in plasma) and dithiothreitol (DTT)

By controlling the lattice anisotropy, one can realize both massive and massless Dirac fermions and observe the phase transition between them. Through explicit calculations, we show that both the Bragg spectroscopy and the atomic density profile in a trap can be used to demonstrate the Dirac fermions and the associated phase transition.

description: On directed Barabasi-Albert networks with two and seven neighbours selected by each added site, the Ising model with spin S=1/2 was seen not to show a spontaneous magnetisation. Instead, the decay time for flipping of the magnetisation followed an Arrhenius law for Metropolis and Glauber algorithms, but for Wolff cluster flipping the magnetisation decayed exponentially with time. On these networks the Ising model spin S=1 is now studied through Monte Carlo simulations. However, in this model, the order-disorder phase transition is well defined in this system. We have obtained a first-order phase transition for values of connectivity m=2 and m=7 of the directed Barabasi-Albert network.

Sedimentary organic matter in the Colorado Group (Cretaceous), Alberta
Creators: name: McCloskey, William Gerrard
Publisher: name: University of British Columbia
Year: 2008

description: The transgressive interval between the top of the Viking Formation and the top of the Second White Speckled Shale in south-central Alberta consists predominantly of mudstones with varying organic richness. The section has been divided into six lithologic "zones" named A through F in ascending stratigraphic order. Existing informal names are used for Zone B (the Fish Scale Zone) and Zone F (the Second White Speckled Shale or Second White Specks). The organic matter in all zones is largely of marine origin. Low TOC values characterize Zone A as a result of destruction of organic matter in a relatively oxidizing environment. All zones above Zone A were deposited under mainly oxygendeficient conditions caused by constriction of the basin due to tectonic movements and by a sea level drop at the onset of Fish Scale Zone time. At peak transgression during deposition of Zone E and the Second White Speckled Shale episodic oxygenation of bottom waters occurred. Relatively high TOC values characterize the Fish Scale Zone, Zone C, Zone D and the Second White Speckled Shale. Low TOC values in Zone E resulted from destruction of organic matter at the sediment/water interface, and possibly as a result of low productivity. The high TOC levels in the Second White Speckled Shale occur in spite of episodic oxygenation of bottom waters and may reflect a global productivity increase at about the Cenomanian-Turonian stage boundary. The present distribution of organic matter in all zones is influenced by a westward increase in thermal maturation. Clay mineralogy is unrelated to organic content. Coarse-grained beds contain less and more refractory organic matter than the finergrained rocks. The amount of silt in mudstones and argillaceous siltstones is unrelated to TOC in all zones except the Fish Scale Zone, in which a increasing silt content correlates to lower TOC. Silt content and oxygen index are related only in Zone D; the correlation is positive. Variations in sedimentation rate derived from thickness variations are correlated in a positive sense for Zone A, the Fish Scale Zone and Zone E. Zone D exhibits a negative correlation, suggestive of dilution. Potential oil exploration targets exist in sandstones in the Fish Scale Zone, at the base of Zone D, and in fractured shales of the Second White Speckled Shale.

description: We study two competing growth models. Each of these models describes the spread of a finite number of infections on a graph. Each infection evolves like an (oriented or unoriented) first passage percolation process except that once a vertex is infected by type $i$ infection, it remains of type $i$ forever. We give results about the shape of the area ultimately infected by the different infections.

description: Social media played a major role in how public health information was shared during the COVID-19 pandemic. Due to aspects such as social distancing, remote work, and worldwide lockdowns, more people relied on social media to stay connected with each other. While public health updates were shared on news outlets on television, there was a shift to seeing the same information condensed into a clip or infographic on social media. While larger public health agencies such as the Center for Disease Control (CDC) were trying to update and share their research as soon as possible, other voices online began to take over. Because anyone with Internet access could use and post on social media, it was very easy to spread information quickly. This became a major concern as users shared posts about health information without evidence. As trust in public health agencies declined over the course of the pandemic, more social media users relied on Internet solutions to "cure" their COVID. This became a major issue for healthcare providers because as they were facing an unprecedented virus with intense patient surges and depleting resources, they had to cope with patients who denied treatment from their providers. Distrust grew rapidly between patients and their providers as more misinformation resonated with patients. This study evaluates the role of health misinformation found on social media and how that impacted the already stressful work environment that providers were facing in healthcare during the COVID-19 pandemic.

description: “Rootless” is a collection of three short stories centered around the South Asian diaspora. It deals with themes of displacement from one’s motherland and the struggle to remain connected to our places of origin while simultaneously navigating the process of growing into our identities. Each story portrays complex family trees—focusing specifically on matrilineal relationships that span multiple generations—and details the way that generational divides and physical distance can create a feeling of rootlessness. In “Chaaya and Jyoti”, a mother and daughter grapple over the implications of sharing a secret outside of their nuclear family unit. In “Ink”, a woman reflects on the way that tattoos connect her to a lineage of women that she is otherwise separate from. In “My Mother, the Squirrel”, a young woman learns more about Hinduism when she starts to believe that her mother has been reincarnated. Ultimately “Rootless” aims to explore the ways that roots can often be an imaginary concept and a double-edged sword—they have the power to tie us down or to provide us with a sense of belonging with the places and people that have grown unfamiliar to us.

La responsabilidad por errores arbitrales. ¿Estatal, civil, ambas o ninguna?

description: El Consejo de Estado estableció que la nación, a través de la rama judicial, está llamada a responder por los perjuicios que sufran los participantes de un arbitraje. El alto tribunal explicó que los árbitros hacen parte de la administración de justicia, y por ello, a raíz de sus desaciertos, es posible iniciar juicios de reparación directa en contra del Estado. En este escrito se pretende demostrar que la aplicación del régimen de error judicial, que es usado cuando se persigue la responsabilidad del juez estatal, no es útil para todos los casos donde se censuran los errores arbitrales, y puede dejar sin indemnización a las víctimas de estos insucesos, por lo que es preferible emplear un sistema de responsabilidad civil contractual.
description: The Council of State established that the nation, through the judicial branch, is liable for the damages suffered by the participants of an arbitration. The high court explained that arbitrators are part of the administration of justice, and therefore, as a result of their errors, it is possible to initiate direct reparation suits against the State. The purpose of this brief is to demonstrate that the application of the judicial error regime, which is used when pursuing the liability of the state judge, is not useful for all cases where arbitral errors are criticized, and may leave the victims of these failures without compensation, so it is preferable to use a system of contractual civil liability.

Shock oscillation model for QPOs in stellar-mass and supermassive black holes

description: We numerically examine centrifugally supported shock waves in 2D rotating accretion flows around a stellar-mass (10M_sun) and a supermassive (10^6M_sun) black holes over a wide range of input accretion rates of 10^7 >\dot M/\dot M_E>10^{-4}. The resultant 2D-shocks are unstable with time and the luminosities show quasi-periodic oscillations (QPOs) with modulations of a factor of 2-3 andwith periods of a tenth seconds to several hours, depending on the black hole masses. The shock oscillation model may explain the intermediate frequency QPOs with 1-10 Hz observed in the stellar-mass black hole candidates and also suggest the existence of QPOs with the period of hours in AGNs. When the accretion rate is low, the luminosity increases in proportion to the accretion rate. However, when the accretion rate exceeds greatly the Eddington critical rate \dot M_E, the luminosity is insensitive to the accretion rate and is kept constantly around 3 L_E. On the other hand, the mass-outflow rate increases in proportion to the accretion rate and it amounts to about a few percent of theinput mass-flow rate.
