description: An inelastic X-ray scattering experiment has been performed in liquid aluminum with the purpose of studying the collective excitations at wavevectors below the first sharp diffraction peak. The high instrumental resolution (up to 1.5 meV) allows an accurate investigation of the dynamical processes in this liquid metal on the basis of a generalized hydrodynamics framework. The outcoming results confirm the presence of a viscosity relaxation scenario ruled by a two timescale mechanism, as recently found in liquid lithium.

description: The trap environment in which Bose-Einstein condensates are generated and/or stored strongly influences the way they interact with light. The situation is analogous to cavity QED in quantum optics, except that in the present case, one tailors the matter-wave mode density rather than the density of modes of the optical field. Just as in QED, for short times, the atoms do not sense the trap and propagate as in free space. After times long enough that recoiling atoms can probe the trap environment, however, the way condensates and light fields are mutually influenced differs significantly from the free-space situation. We use as an example the condensate collective atomic recoil laser, which is the atomic matter-wave analog of the free-electron laser.

title: The Influence of Temperature Salinity and Postlarval Transport on the Distribution of Juvenile Spiny Lobsters, Panulirus argus, in Florida Bay

description: Florida Bay is a major nursery for the Caribbean spiny lobster, Panulirus argus. The Bay contains a series of hardbottom or seagrass-covered basins separated by mudbanks, which serve as barriers to water circulation and presumably to transport of postlarvae. Temperatures can fluctuate dramatically in the basins and salinities range from 35 ppt to > 50 ppt. In this study I: i) investigated the physiological tolerance of spiny lobster postlarvae to combinations of temperature and salinity representative of conditions in Florida Bay, and ii) examined how postlarval availability and habitat structure influence spiny lobster recruitment into basins. I measured juvenile lobster abundance, postlarval settlement, and nursery habitat structure along five transects from the middle Florida Keys into Florida Bay. Concurrently, postlarval survival, time-to-metamorphosis, and size at metamorphosis were measured in a laboratory experiment in which postlarvae were reared at four temperatures (18°C, 22°C, 29°C and 33°C) and four salinities (25, 35, 45 and 50 ppt). Postlarvae are not regularly transported beyond the mudbanks ringing Florida Bay; however, diver surveys of juvenile abundance indicate that some postlarvae do recruit beyond a few of these banks into basins (e.g., Twin Key Basin) where habitat and environmental conditions are suitable. Postlarvae can withstand a range of temperatures and salinities, but survival was significantly reduced at extreme temperatures (e.g., 18°C and 33°C) and salinities other than 35 ppt. Thus, during extended warm or cold periods, the hypersaline conditions of Florida Bay may restrict recruitment of Panulirus argus to areas near the Florida Keys where salinities of 35 ppt predominate.

description: In this work we characterize the distribution of Dark Matter (DM) in the Milky Way (MW), and its uncertainties, adopting the well known "Rotation Curve" method. We perform a full marginalization over the uncertainties of the Galactic Parameters and over the lack of knowledge on the morphology of the baryonic components of the Galaxy. The local DM density rho0 is constrained to the range 0.3 - 0.8 GeV/cm3 at the 2 sigma level, and has a strong positive correlation to R0, the local distance from the Galactic Center (GC). The not well-known value of R0 is thus, at the moment, a major limitation in determining rho0. Similarly, we find that the inner slope of the DM profile, gamma, is very weakly constrained, showing no preference for a cored profile (gamma~0) or a cuspy one (gamma~[1.0,1.4]). Some combination of parameters can be, however, strongly constrained. For example the often used standard rho0=0.3 GeV/cm3, R0=8.5 kpc is excluded at more than 4 sigma. We release the full likelihood of our analysis in a tabular form over a multidimensional grid in the parameters characterizing the DM distribution, namely the scale radius Rs, the scale density rhos, the inner slope of the profile gamma, and R0. The likelihood can be used to include the effect of the DM distribution uncertainty on the results of searches for an indirect DM signal in gamma-rays or neutrinos, from the GC, or the Halo region surrounding it. As one example, we study the case of the GC excess in gamma rays. Further applications of our tabulated uncertainties in the DM distribution involve local DM searches, like direct detection and anti-matter observations, or global fits combining local and GC searches.

description: We point out that for a class of `new inflation' models in supergravity the required initial value of the inflaton field is dynamically set if there is another inflation (`pre-inflation') before the `new inflation'. We study the dynamics of both inflatons by taking a hybrid inflation model for the `pre-inflation' as an example. We find out that our `new inflation' model provides reheating temperatures T_R \simeq 10 MeV - 10^4 GeV low enough to avoid the gravitino problem even in gauge-mediated supersymmetry-breaking models. We also construct a model where the scale for the `new inflation' is generated by nonperturbative dynamics of a supersymmetric gauge theory.

description: Excerpts from the report: Many poultry wholesalers in urban areas need new facilities because their present ones are obsolete, inadequate, or no longer in the most advantageous location. Some wholesalers are operating in old buildings never intended for handling food, which have structural and space limitations that prevent the firm from using modern handling equipment and methods. The purpose of this report is to provide information to help a poultry wholesaler lay out the space his firm would occupy in a building in a food center. The information includes a description of buildings in food distribution centers, principles of layout planning, their application to a poultry wholesale firm, a step-by-step procedure for planning a layout, and an example of a layout. This layout is intended to serve as a guide to the poultry wholesaler who will be planning the layout for his firm.

description: We consider a cosmological model with an interaction between dark matter and dark energy which leaves the background cosmology unaffected and only affects the evolution of the perturbations. This is achieved by introducing a coupling given in terms of the relative velocities of dark matter and dark energy. This interaction has the distinctive feature of appearing predominantly on small scales, where peculiar velocities can become important. We confront the predictions of the model to cosmological observations and find a potential alleviation of the known tension in the amplitude of density perturbations as measured by low redshift galaxy surveys and the Planck data. The model also predicts a shift in the turnover of the matter power spectrum which does not depend on the horizon at equality (fixed by the background cosmology and, thus, unaffected by the perturbations) and is entirely due to the interaction between dark matter and dark energy. A bias in the peculiar velocity between baryons and dark matter is also shown to be a unique feature of this type of interactions in the dark sector.

description: L'ergothérapie est une profession de la santé basée sur les sciences de l'occupation (World federation of occupational therapy [WFOT], 2013). Elle s'insère dans un travail interprofessionnel sollicitant une collaboration efficace pour favoriser une approche optimale centrée sur le client (Louis Simonet, 2017). Cette collaboration est un processus en perpétuelle construction et peut-être influencée par de multiples facteurs. L'un de ceux-ci correspond aux représentations sociales construites implicitement par les différents-es professionnels-elles. Un manque de connaissances quant aux rôles des autres membres de l’équipe interprofessionnelles peut provoquer une inadéquation entre les véritables rôles et les représentations de chacun d'eux-elles. En ce qui concerne les rôles et les fonctions des ergothérapeutes, un manque de connaissances de la part des autres professionnels-elles a été identifié (Patel & Shriber, 2001). Les conséquences en sont multiples et portent, par exemple, sur le sentiment de reconnaissance des ergothérapeutes (Jamnadas, Burns & Paul, 2002 ; Patel & Shriber, 2001 ; Pottenbaum & Svinarich, 2005 ; Smith & Mackenzie, 2011). Il est important que les membres de l’équipe interprofessionnelle soient conscients-es des représentations véhiculées concernant l'ensemble des professions. Cela permet d'éviter un impact négatif sur la collaboration. Les ergothérapeutes sont souvent amenés-ées à collaborer avec l'équipe infirmière, particulièrement en milieu hospitalier. Dès lors, ce travail s'intéresse à la manière dont les infirmiers-ères, exerçant dans un milieu hospitalier de Suisse romande, se représentent les rôles des ergothérapeutes avec qui ils-elles collaborent et comment leurs représentations influencent cette collaboration. Les questions d'étude visent à explorer les représentations, ainsi que l'impact de celles-ci sur la collaboration interprofessionnelle. Dans cette optique, des entretiens semi-dirigés ont été réalisés avec sept infirmiers-éres travaillant soit sans un service de réadaptation, soit dans un service de soins palliatifs d'un même hôpital. Les résultats et l'analyse des entretiens ont permis d'identifier que les représentations des infirmiers-ères sur le rôles des ergothérapeutes au sein des domaines de réadaptation et de soins palliatifs sont relativement complètes, bien que leurs connaissances puissent être limitées notamment en fonction du nombre d'années de pratique et de collaboration dans les domaines précités.

description: Abstract

In order to reduce cost-related risks and increase the overall allocation of resources, accurate cost estimation is very essential when managing construction projects. This paper studies the cost estimations in construction undertakings within the Afgoi District in Somalia and aims to find which particular factors influence cost estimation. Some of these would include the project scope, existing competition, prevailing wages, materials supply, and the processes of estimation.

A combination of techniques was adopted in which information was sought via questionnaires and interviews from project managers, engineers, and cost estimators. Shortfalls in technical and financial data, along with constraints such as lack of time and overestimated levels of competency, lead to adverse estimation of expenditure. In addition to these internally driven elements, other factors such as changing prices of raw materials, government policies, and unanticipated climatic conditions also affect the accuracy of cost estimation in the project.

The study shows that cost estimates can be improved by spending more effort on planning or putting in place advanced data collection methods or even sophisticated cost estimation models. Some suggestions are better data gathering methods, improved training, enhanced project planning, crafted in-depth detail for frameworks, and partnered with standard structures for estimating prices to increase accuracy and effectiveness.

The research has shown that better training, more effective data collection, and advanced cost estimation models will improve the estimation of costs. Investing in workforce training and development and enhancing the planning phase of construction projects along with the development of universal and specific estimation frameworks are recommended in order to improve the efficiency and accuracy of construction projects. This will be helpful to the construction firms, policymakers, and project managers in Somalia towards better cost estimation and higher project success probabilities.

Luttinger liquids coupled by hopping

description: The stability of the Luttinger liquid to small transverse hopping has been studied from several points of view. The renormalization group approach in particular has been criticized because it does not take explicitly into account the difference between spin and charge velocities and because the interaction should be turned-on before the transverse hopping if the stability of the Luttinger liquid is a non-perturbative effect. An approach that answers both of these objections is explained here. It shows that the Luttinger liquid is unstable to arbitrarily small transverse hopping. The crossover temperatures below which either transverse coherent band motion or long-range order start to develop can be finite even when spin and charge velocities differ. Explicit scaling relations for these one-particle and two-particle crossover temperatures are derived in terms of transverse hopping, spin and charge velocities and anomalous exponents. The renormalization group results are recovered as special cases when spin and charge velocities are identical. The results compare well with recent experiments presented at this conference. Magnetic field effects are alluded to.

description: In certain new physics scenarios, a singly charged Higgs boson can couple to both fermions and $W^\pm Z$ at tree level. We develop new strategies beyond current experimental searches using $pp\to jjH^\pm$, $H^\pm \to tb $ at the Large Hadron Collider (LHC). With the effective $H^\pm W^\mp Z$ and $H^\pm tb$ couplings we perform a model-independent analysis at the collision energy $\sqrt{s}=13$~TeV with the integrated luminosity of $3~\text{ab}^{-1}$. We derive the discovery prospects and exclusion limits for the charged Higgs boson in the mass range from 200~GeV to 1~TeV. With $|F_{WZ}|,|A_t|\sim 0.5-1.0$ and $300~\text{GeV}\lesssim m_{H^\pm}\lesssim 400~\text{GeV}$, we point out that a discovery significance of $5σ$ can be achieved. The constraints and projected sensitivities are also discussed in a realistic model, i.e., the modified Georgi-Machacek model without custodial symmetry. Our proposed search would provide direct evidence for a charged Higgs boson $H^\pm$ that couples to $W^\pm Z$ and $tb$, which can have better sensitivity to the couplings of $H^\pm W^\mp Z$ and $H^\pm tb$ than current searches.

Their lattice dynamics and self-consistently screened electron-phonon coupling are evaluated within local density functional theory and using linear-muffin-tin -orbital basis set. We conclude that our method provides the description of electron-phonon interactions in tested materials with the accuracy 10%.

description: U(1) gauge theory on ${\bf R}^4$ is known to possess an electric-magnetic duality symmetry that inverts the coupling constant and extends to an action of $SL(2,{\bf Z})$. In this paper, the duality is studied on a general four-manifold and it is shown that the partition function is not a modular-invariant function but transforms as a modular form. This result plays an essential role in determining a new low-energy interaction that arises when N=2 supersymmetric Yang-Mills theory is formulated on a four-manifold; the determination of this interaction gives a new test of the solution of the model and would enter in computations of the Donaldson invariants of four-manifolds with $b_2^+\leq 1$. Certain other aspects of abelian duality, relevant to matters such as the dependence of Donaldson invariants on the second Stieffel-Whitney class, are also analyzed.

description: Excerpts from the report: A study was made to determine the most economical and efficient means of supplying refrigeration to a hypothetical, four-building food distribution center housing 34 firms in a wholesale food distribution center in Chicago, Ill. The firms buy and sell fresh fruits and vegetables, meats and meat products, poultry, eggs, and groceries. It was assumed that the 34 firms would need refrigeration for 2 rooms at -20° F., 11 rooms at -10°, 1 room at 25°, 17 rooms at 32°, 7 rooms at 40°, 1 room at 45°, 19 rooms at 50°, and 5 rooms at 72°. In this report, specific data, material, designs, and evaluations have been developed to determine an efficient system for providing the refrigeration requirement in such food distribution centers. Weather data and electrical, labor, and material costs used in this report reflect those current in Chicago at the time this study was made.

description: Portion size is recognized as a major determinant of food intake, at least over the short term, and could be related to overconsumption and obesity. In this study, we developed and evaluated a new visual measure of portion size (PS), examined whether the PS of chicken, ice cream, and soda varied among people in Brazil, France, and the USA, and tested whether PS was related to gender, body mass index, body weight, and socioeconomic status. We conducted a cross-sectional study using online convenience samples of university students (total N = 1391). Across all three foods, French personal and country PSs were significantly smaller than the other three countries. Estimated country PS was reliably larger than personal PS. Women’s personal PSs were smaller than men’s, but women’s and men’s estimates for country PS were similar. French personal and country PSs were the lowest. Some PSs had a weak but significant correlation with SES but were not significantly related to either weight or BMI. The study confirms French-American differences in personal PS and demonstrates that perceived norms correspond to individual PS.

description: Taking advantage of the known exact mapping of the one-dimensional Hard Core Bose (HCB) fluid onto a non-interacting spinless fermion gas, we examine in full detail a thought experiment on cold atoms confined in a quasi-one-dimensional trap, in order to investigate the emergence of the analogue Hawking radiation. The dynamics of a gas of interacting bosons impinging on an external potential is exactly tracked up to the reach of a stationary state. Under few strict conditions on the experimental parameters, the stationary state is shown to be described asymptotically by a thermal distribution, precisely at the expected (analogue) Hawking temperature. However, we find that in most experimental conditions the emerging `Hawking-like radiation' is not thermal. This analysis provides a novel many-body microscopic interpretation of the Hawking mechanism, together with useful limits and conditions for the design of future experiments in Bose-Einstein condensates.

Implementation of a palliative care screening tool in the intensive care unit: a quality improvement project
Creators: name: DelCore, Nicole
Publisher: name: No Publisher Supplied
Year: 2021

description: Purpose statement: The purpose of the project was to address unmet palliative care needs in the ICU by implementing a palliative care screening tool at a private, not-for-profit hospital, following The Iowa Model (Iowa Model Collaborative, 2017). Methodology: This is a quality improvement project with a retrospective and prospective chart review design. An initial retrospective chart review was performed by the principal investigator (PI) to determine how many patients received a palliative care consult over six weeks prior to the implementation of a screening tool. A palliative care screening tool was created using the guidelines provided by the Improving Palliative Care (IPAL)-ICU project. The final screening tool represents the specific ICU that it was used in and consists of eight evidence-based screening triggers. The implementation period took place over six weeks. Once this was completed, the PI performed a prospective chart review to determine the number of palliative care consults ordered during that time. Results: A total of 34 nurses consented to participate in this quality improvement project to address the need for a palliative care screening tool in the ICU to identify patients appropriate for palliative care services. The retrospective chart review from July 13th, 2020 to August 23rd, 2020, revealed 165 ICU admissions. Of those 165 patients, 21of them received a palliative care consult. The total number of patient admissions to the ICU during the six-week project implementation period, from August 24th, 2020 to October 4th, was 239. Of those 239 patients, a total of 63 palliative care consultations were received (47 patients from screening and 16 routinely obtained consults). Based on the retrospective chart review, before implementing the screening tool, there was a 12.7% palliative care consultation rate for ICU admissions. Based on the pre-intervention data, at a 12.7% consultation rate, it was expected that there would be 30 palliative care consults for the 239 admitted patients. Data collection revealed a total of 63 palliative care consults with the implementation of the screening tool. The prospective chart review revealed that with the implementation of study intervention, a palliative care screening tool, there was a 26.4% palliative care consultation rate for ICU admissions. A chi-square test was used to calculate statistical significance. There was a statically significant difference between the observed and expected palliative care consults with the implementation of a screening tool. X2 (1) = 41.51, p

description: Recently, two nonempirical hybrid functionals, dielectric-dependent range-separated hybrid functional based on the Coulomb-attenuating method (DD-RSH-CAM) and doubly screened hybrid functional (DSH), have been suggested by [Chen et al, Phys. Rev. Mater. 2, 073803 (2018)] and [Cui et al, J. Phys. Chem. Lett. 9, 2338 (2018)], respectively. These two hybrid functionals are both based on a common model dielectric function approach, but differ in the way how to non-empirically obtain the range-separation parameter. By retaining the full short-range Fock exchange and a fraction of the long-range Fock exchange that equals the inverse of the dielectric constant, both DD-RSH-CAM and DSH turn out to perform very well in predicting the band gaps for a large variety of semiconductors and insulators. Here, we assess how these two hybrid functionals perform on challenging antiferromagnetic transition-metal monoxides MnO, FeO, CoO, and NiO by comparing them to other conventional hybrid functionals and the $GW$ method. We find that single-shot DD0-RSH-CAM and DSH0 improve the band gaps towards experiments as compared to conventional hybrid functionals. The magnetic moments are slightly increased, but the predicted dielectric constants are decreased. The valence band density of states (DOS) predicted by DD0-RSH-CAM and DSH0 are as satisfactory as HSE03 in comparison to experimental spectra, however, the conduction band DOS are shifted to higher energies by about 2 eV compared to HSE03. Self-consistent DD-RSH-CAM and DSH deteriorate the results with a significant overestimation of band gaps.

description: We develop a new approach to characterizing the morphology of rough surfaces based on the analysis of the scaling properties of contour loops, i.e. loops of constant height. Given a height profile of the surface we perform independent measurements of the fractal dimension of contour loops, and the exponent that characterizes their size distribution. Scaling formulas are derived and used to relate these two geometrical exponents to the roughness exponent of a self-affine surface, thus providing independent measurements of this important quantity. Furthermore, we define the scale dependent curvature and demonstrate that by measuring its third moment departures of the height fluctuations from Gaussian behavior can be ascertained. These nonlinear measures are used to characterize the morphology of computer generated Gaussian rough surfaces, surfaces obtained in numerical simulations of a simple growth model, and surfaces observed by scanning-tunneling-microscopes. For experimentally realized surfaces the self-affine scaling is cut off by a correlation length, and we generalize our theory of contour loops to take this into account.

description: Recently there is a surge of interest in network geometry and topology. Here we show that the spectral dimension plays a fundamental role in establishing a clear relation between the topological and geometrical properties of a network and its dynamics. Specifically we explore the role of the spectral dimension in determining the synchronization properties of the Kuramoto model. We show that the synchronized phase can only be thermodynamically stable for spectral dimensions above four and that phase entrainment of the oscillators can only be found for spectral dimensions greater than two. We numerically test our analytical predictions on the recently introduced model of network geometry called Complex Network Manifolds which displays a tunable spectral dimension.

description: This is Supplementary Information for: Understanding seismotectonic activity preceding major earthquakes is critical for elucidating fault mechanics and improving hazard assessment. Here, we analyze seismic and geodetic data for the 2023 Kahramanmaraş Mw≥7.6 earthquake doublet along the East Anatolian Fault (EAF) in Türkiye and compare them with data associated to two earlier Mw≥6.1 events along the EAF. Remarkably, the analyzed data demonstrate clear, contrasting behaviors prior to catastrophic earthquake rupture. Northeastern segments show relatively linear fault traces, with interseismic slip rates reaching ~7 mm/a. These segments exhibit significant creep and channeled or on-fault seismic slip, with mainshocks typically preceded by concentrated seismic moment at their epicenters months in advance. In contrast, the EAF southwestern section is more complex, branching into multiple segments with interseismic slip rates as slow as ~0.7 mm/a, partitioned slip, and unchanneled or off-fault seismic slip. Premainshock activity in this region is diffusely distributed and the seismic moment shows weak or no spatial correlation with the epicenters of the impending mainshocks. These results provide critical information and strategies for anticipating and mitigating seismic risk. Combining seismotectonic characterization of seismogenic fault segments with continuous monitoring of tectonic slip could prove eventually essential for real-time assessment of the timing and location of future mainshocks.

description: One of the most problematic aspects in the creation of spin-offs by university personnel concerns the relationship between entrepreneurial activity and research activity by researcher-entrepreneurs. The literature has expressed varying and opposing views as to the nature of the relationship but very little has been produced to empirically legitimate one position or another. The present work proposes to address this shortcoming by exploring the relationship existing between academic spin-off generation and the research performance of enterprise founders. The study investigates whether, and to what extent, scientific performance by academic entrepreneurs is different than that of their colleagues, and if the involvement in entrepreneurial activity has an influence on the individual's research activity. The research questions are answered by considering all spin-offs generated by Italian universities over the period 2001-2008 and evaluating, through a bibliometric approach, the scientific performance of founders relative to that of their colleagues who carry out research in the same field. The data show better scientific performance by the researcher-entrepreneurs than that of their colleagues and in addition, although there are some variations across fields, the creation of a spin-off does not seem, on average, to have negative effects on the scientific performance of the founders.
