description: The purpose of this research study ‘Recreational Programming for Commuting Students’ is to determine if time spent commuting to campus is a large influencer regarding student’s decisions to participate in recreational activities on UBC’s Vancouver campus, or if it is due to communication techniques used. The commuter students being addressed range from a total of zero minutes up to 3 hours each day. The length of these commutes is inclusive of both directions, to and from campus. This population of commuter students was chosen to see if there are large differences in a student’s perception of their ability to manage time, and if that becomes a determinant for students to participate in recreational activities. This research will examine the similarities or difference between these commuting students to see any other varying forms of constraints that students may face. Examples of relevant considerations include time management, social skills, skills to be successful in the activity, money constraints, and sense of inclusion/belonging (MacRae, 2011). Studies show that the average time to commute one way has gone up to about 26 minutes, with many people commuting for much longer, and therefore taking away time where individuals could be active (The Astonishing…, 2016). This research study will send out surveys through email to participants in an attempt to overcome time constraints that had been commented on by participants. These surveys will inquire about students issues within current communication methods among campus, and result in a discussion to determine a possible plan of action to improve these strategies. In researching the issues surrounding communication techniques of recreational programming, a subsequent goal of this study would be to increase recreational participation among commuter students.

description: Quantum coherence is a crucial resource for quantum information processing. By employing the language of coherence orders largely applied in NMR systems, quantum coherence has been currently addressed in terms of multiple quantum coherences (MQCs). Here we investigate the $α$-MQCs, a novel class of multiple quantum coherences which is based on $α$-relative purity, an information-theoretic quantifier analogous to quantum fidelity and closely related to Rényi relative entropy of order $α$. Our framework enables linking $α$-MQCs to Wigner-Yanase-Dyson skew information (WYDSI), an asymmetry monotone finding applications in quantum thermodynamics and quantum metrology. Furthermore, we derive a family of bounds on $α$-MQCs, particularly showing that $α$-MQC define a lower bound to quantum Fisher information (QFI). We illustrate these ideas for quantum systems described by single-qubit states, two-qubit Bell-diagonal states, and a wide class of multiparticle mixed states. Finally, we investigate the time evolution of the $α$-MQC spectrum and the overall signal of relative purity, by simulating the time reversal dynamics of a many-body all-to-all Ising Hamiltonian and comment on applications to physical platforms such as NMR systems, trapped ions, and ultracold atoms.

description: We obtain the band edge eigenfunctions and the eigenvalues of solvable periodic potentials using the quantum Hamilton - Jacobi formalism. The potentials studied here are the Lam{é} and the associated Lam{é} which belong to the class of elliptic potentials. The formalism requires an assumption about the singularity structure of the quantum momentum function $p$, which satisfies the Riccati type quantum Hamilton - Jacobi equation, $ p^{2} -i \hbar \frac{d}{dx}p = 2m(E- V(x))$ in the complex $x$ plane. Essential use is made of suitable conformal transformations, which leads to the eigenvalues and the eigenfunctions corresponding to the band edges in a simple and straightforward manner. Our study reveals interesting features about the singularity structure of $p$, responsible in yielding the band edge eigenfunctions and eigenvalues.

Year: 2024

description: This comprehensive review delves into implementing Activity-Based Costing (ABC) in healthcare systems, offering detailed insights into its impact on cost management, financial performance, and resource allocation. ABC, a sophisticated cost accounting methodology, holds the potential to revolutionize how healthcare organizations understand and control expenses. The review systematically follows ABC's four-step approach, elucidating its principles and emphasizing its benefits, challenges, and outcomes based on existing studies.

The benefits of ABC implementation in healthcare are scrutinized, highlighting its capacity to deliver a nuanced understanding of costs and identify cost-saving opportunities. By allocating costs based on the actual consumption of resources by specific activities, ABC enhances resource allocation, leading to financial savings. Identifying cost drivers is a crucial advantage, enabling organizations to optimize processes, streamline operations, and improve overall efficiency.

However, the review acknowledges the challenges associated with ABC implementation in healthcare, including comprehensive data collection, organizational readiness, and the complexity of healthcare processes. The analysis incorporates successful ABC implementations in developed and developing countries, underscoring its adaptability and effectiveness.

Results from developed countries showcase significant cost reductions, enhanced resource allocation, improved decision-making, and increased transparency in cost reporting. In developing countries, ABC has demonstrated effectiveness in managing costs, improving financial performance, and contributing to the overall sustainability of healthcare facilities. Case studies underscore ABC’s role in promoting accountability, transparency, and improved patient outcomes.

The review highlights the need for further research, particularly in developing countries like Ghana, to explore ABC implementation's feasibility, benefits, and challenges. Despite challenges, ABC stands out as a valuable methodology for enhancing cost management practices, optimizing resource utilization, and improving the efficiency and sustainability of healthcare delivery. This transformative approach has the potential to reshape the landscape of healthcare cost management globally, ensuring the delivery of high-quality, cost-effective healthcare services.

description: Abstract: The measurements of quasi-periodic oscillations (QPOs) provide a quite powerful tool to test the nature of astrophysical black hole candidates in the strong gravitational field regime. In this paper, we use QPOs within the relativistic precession model to test a recently proposed family of rotating black hole mimickers, which reduce to the Kerr metric in a limiting case, and can represent traversable wormholes or regular black holes with one or two horizons, depending on the values of the parameters. In particular, assuming that the compact object of GRO J1655-40 is described by a rotating black hole mimicker, we perform a χ-square analysis to fit the parameters of the mimicker with two sets of observed QPO frequencies from GRO J1655-40. Our results indicate that although the metric around the compact object of GRO J1655-40 is consistent with the Kerr metric, a regular black hole with one horizon is favored by the observation data of GRO J1655-40.

description: Motivated by the vacuum selection problem of string/M theory, we study a new geometric invariant of a positive Hermitian line bundle $(L, h)\to M$ over a compact Kähler manifold: the expected distribution of critical points of a Gaussian random holomorphic section $s \in H^0(M, L)$ with respect to the Chern connection $\nabla_h$. It is a measure on $M$ whose total mass is the average number $\mathcal{N}^{crit}_h$ of critical points of a random holomorphic section. We are interested in the metric dependence of $\mathcal{N}^{crit}_h$, especially metrics $h$ which minimize $\mathcal{N}^{crit}_h$. We concentrate on the asymptotic minimization problem for the sequence of tensor powers $(L^N, h^N)\to M$ of the line bundle and their critical point densities $\mathcal{K}^{crit}_{N,h}(z)$. We prove that $\mathcal{K}^{crit}_{N,h}(z)$ has a complete asymptotic expansion in $N$ whose coefficients are curvature invariants of $h$. The first two terms in the expansion of $\mathcal{N}^{crit}_{N,h}$ are topological invariants of $(L, M)$. The third term is a topological invariant plus a constant $β_2(m)$ (depending only on the dimension $m$ of $M$) times the Calabi functional $\int_M ρ^2 dV_h$, where $ρ$ is the scalar curvature of the Kähler metric $ω_h:=\frac i2 Θ_h$. We give an integral formula for $β_2(m)$ and show, by a computer assisted calculation, that $β_2(m)>0$ for $m\leq 5$, hence that $\mathcal{N}^{crit}_{N,h}$ is asymptotically minimized by the Calabi extremal metric (when one exists). We conjecture that $β_2(m)>0$ in all dimensions, i.e. the Calabi extremal metric is always the asymptotic minimizer.

description: All measurement of human behavior which is dependent on a subjective response is confounded by a peculiar paradox. Though every aspect of a stimulus may lend itself to the most precise measurement, and may be under the most perfect control, once this known stimulus enters the vast unknown of the human psyche, and that self must consciously perceive the stimulus, and must communicate his awareness of it, then all knowledge of the stimulus may be lost in the waste of reliability of the response.

description: We propose a new data-driven reduced order model (ROM) framework that centers around the hierarchical structure of the variational multiscale (VMS) methodology and utilizes data to increase the ROM accuracy at a modest computational cost. The VMS methodology is a natural fit for the hierarchical structure of the ROM basis: In the first step, we use the ROM projection to separate the scales into three categories: (i) resolved large scales, (ii) resolved small scales, and (iii) unresolved scales. In the second step, we explicitly identify the VMS-ROM closure terms, i.e., the terms representing the interactions among the three types of scales. In the third step, we use available data to model the VMS-ROM closure terms. Thus, instead of phenomenological models used in VMS for standard numerical discretizations (e.g., eddy viscosity models), we utilize available data to construct new structural VMS-ROM closure models. Specifically, we build ROM operators (vectors, matrices, and tensors) that are closest to the true ROM closure terms evaluated with the available data. We test the new data-driven VMS-ROM in the numerical simulation of four test cases: (i) the 1D Burgers equation with viscosity coefficient $ν= 10^{-3}$; (ii) a 2D flow past a circular cylinder at Reynolds numbers $Re=100$, $Re=500$, and $Re=1000$; (iii) the quasi-geostrophic equations at Reynolds number $Re=450$ and Rossby number $Ro=0.0036$; and (iv) a 2D flow over a backward facing step at Reynolds number $Re=1000$. The numerical results show that the data-driven VMS-ROM is significantly more accurate than standard ROMs.

description: Kinetics of collapse and explosion transitions in microcanonical self-gravitating ensembles is analyzed. A system of point particles interacting via an attractive soft Coulomb potential and confined to a spherical container is considered. We observed that for 100--200 particles collapse takes $10^3$ -- $10^4$ particle crossing times to complete, i. e., it is by 2-3 orders of magnitude slower than velocity relaxation. In addition, it is found that the collapse time decreases rapidly with the increase of the softcore radius. We found that such an anomalously long collapse time is caused by the slow energy exchange between a higher-temperature compact core and relatively cold diluted halo. The rate of energy exchange between the faster modes of the core particles and slower-moving particles of the halo is exponentially small in the ratio of the frequencies of these modes. As the softcore radius increases, and the typical core modes become slower, the ratio of core and halo frequencies decreases and the collapse accelerates. Implications to astrophysical systems and phase transition kinetics are discussed.

description: Accurate and real-time surgical instrument segmentation is important in the endoscopic vision of robot-assisted surgery, and significant challenges are posed by frequent instrument-tissue contacts and continuous change of observation perspective. For these challenging tasks more and more deep neural networks (DNN) models are designed in recent years. We are motivated to propose a general embeddable approach to improve these current DNN segmentation models without increasing the model parameter number. Firstly, observing the limited rotation-invariance performance of DNN, we proposed the Multi-Angle Feature Aggregation (MAFA) method, leveraging active image rotation to gain richer visual cues and make the prediction more robust to instrument orientation changes. Secondly, in the end-to-end training stage, the auxiliary contour supervision is utilized to guide the model to learn the boundary awareness, so that the contour shape of segmentation mask is more precise. The proposed method is validated with ablation experiments on the novel Sinus-Surgery datasets collected from surgeons' operations, and is compared to the existing methods on a public dataset collected with a da Vinci Xi Robot.

Publisher: name: arXiv
Year: 2003
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We propose an alternative interpretation of Markovian transport models based on the well-mixedness condition, in terms of the properties of a random velocity field with second order structure functions scaling linearly in the space time increments. This interpretation allows direct association of the drift and noise terms entering the model, with the geometry of the turbulent fluctuations. In particular, the well known non-uniqueness problem in the well-mixedness approach is solved in terms of the antisymmetric part of the velocity correlations; its relation with the presence of non-zero mean helicity and other geometrical properties of the flow is elucidated. The well-mixedness condition appears to be a special case of the relation between conditional velocity increments of the random field and the one-point Eulerian velocity distribution, allowing generalization of the approach to the transport of non-tracer quantities. Application to solid particle transport leads to a model satisfying, in the homogeneous isotropic turbulence case, all the conditions on the behaviour of the correlation times for the fluid velocity sampled by the particles. In particular, correlation times in the gravity and in the inertia dominated case, respectively, longer and shorter than in the passive tracer case; in the gravity dominated case, correlation times longer for velocity components along gravity, than for the perpendicular ones. The model produces, in channel flow geometry, particle deposition rates in agreement with experiments.

description: We present spatially-resolved internal kinematics and stellar chemical abundances for a sample of dwarf elliptical (dE) galaxies in the Virgo Cluster observed with Keck/ESI. We find that 4 out of 17 dEs have major axis rotation velocities consistent with rotational flattening, while the remaining dEs have no detectable major axis rotation. Despite this difference in internal kinematics, rotating and non-rotating dEs are remarkably similar in terms of their position in the Fundamental Plane, morphological structure, stellar populations, and local environment. We present evidence for faint underlying disks and/or weak substructure in a fraction of both rotating and non-rotating dEs, but a comparable number of counter-examples exist for both types which show no evidence of such structure. Absorption-line strengths were determined based on the Lick/IDS system (Hbeta, Mgb, Fe5270, Fe5335) for the central region of each galaxy. We find no difference in the line-strength indices, and hence stellar populations, between rotating and non-rotating dE galaxies. The best-fitting mean age and metallicity for our 17 dE sample are 5 Gyr and Fe/H = -0.3 dex, respectively, with rms spreads of 3 Gyr and 0.1 dex. The majority of dEs are consistent with solar alpha/Fe abundance ratios. By contrast, the stellar populations of classical elliptical galaxies are, on average, older, more metal rich, and alpha-enhanced relative to our dE sample. The local environments of both dEs types appear to be diverse in terms of their proximity to larger galaxies in real or velocity space within the Virgo Cluster. Thus, rotating and non-rotating dEs are remarkably similar in terms of their structure, stellar content, and local environments, presenting a significant challenge to theoretical models of their formation.

description: The fluid-gravity correspondence documents a precise mathematical map between a class of dynamical spacetime solutions of the Einstein field equations of gravity and the dynamics of its corresponding dual fluid flows governed by the Navier-Stokes (NS) equations of hydrodynamics. This striking connection has been explored in several dynamics-based approaches and has surfaced in various forms over the past four decades. In a recent construction, it has been shown that the manifold properties of geometric duals are in fact intimately connected to the dynamics of incompressible fluids, thus bypassing the conventional on-shell standpoints. Following such a prescription, we construct the geometrical description that effectively captures the dynamics of an incompressible NS fluid with respect to a uniformly rotating frame. We propose the gravitational dual(s) described by bulk metric(s) in $(p+2)$-dimensions such that the equations of parallel transport of an appropriately defined bulk velocity vector field when projected onto an induced timelike hypersurface require that the incompressible NS equation of a fluid relative to a uniformly rotating frame be satisfied at the relevant perturbative order in $(p+1)$-dimensions. We argue that free fluid flows on manifold(s) described by the proposed metric(s) can be effectively considered as an equivalent theory of non-relativistic viscous fluid dynamics with respect to (w.r.t) a uniform rotating frame. We also present suggestive insights as to how space-time rotation parameters encode information pertaining to the inertial effects in the corresponding fluid dual.

description: All measurement of human behavior which is dependent on a subjective response is confounded by a peculiar paradox. Though every aspect of a stimulus may lend itself to the most precise measurement, and may be under the most perfect control, once this known stimulus enters the vast unknown of the human psyche, and that self must consciously perceive the stimulus, and must communicate his awareness of it, then all knowledge of the stimulus may be lost in the waste of reliability of the response.

description: The governmental accounting system employed in Thailand was devised and designed about twenty five years ago by a few high government executives who possessed a knowledge of accounting. Most of these men, during that time, had received their formal education and training in Great Britain. Consequently, it was but natural that these men would be influenced by the ideas of the British.

description: We calculate the Casimir force or dispersive van der Waals force between a spherical nanoparticle and a planar substrate, both with arbitrary dielectric properties. We show that the force between a sphere and a plane can be calculated through the interacting surface plasmons of the bodies. Using a Spectral Representation formalism, we show that the force of a sphere made of a material A and a plane made of a material B, differ from the case when the sphere is made of B, and the plane is made of A. We found that the difference depends on the plasma frequency of the materials, the geometry, and the distance of separation between sphere and plane. The differences show the importance of the geometry, and make evident the necessity of realistic descriptions of the sphere-plane system beyond the Derjaguin Approximation or Proximity Theorem Approximation.
Marketing Fruits and Vegetables in the United States, with Particular Emphasis on Changes between 1940-1950

description: The fact that fruits and vegetables are a perishable agricultural product and that their daily consumption is of acknowledged nutritional value makes the study of their marketing a subject of importance to the economics of consumption. In a real sense, the almost year-round daily consumption of California oranges in Maine and Maine potatoes in California is a remarkable economic phenomenon. Equally remarkable is not only the extent to which the American housewife can be supplied daily with a wide variety of fruits and vegetables but the extent to which their preparation for the table requires less and less of her time because of changes in processing.
Quantum mechanics and the equivalence principle

description: A quantum particle moving in a gravitational field may penetrate the classically forbidden region of the gravitational potential. This raises the question of whether the time of flight of a quantum particle in a gravitational field might deviate systematically from that of a classical particle due to tunnelling delay, representing a violation of the weak equivalence principle. I investigate this using a model quantum clock to measure the time of flight of a quantum particle in a uniform gravitational field, and show that a violation of the equivalence principle does not occur when the measurement is made far from the turning point of the classical trajectory. I conclude with some remarks about the strong equivalence principle in quantum mechanics.

description: We investigate the radio-frequency spectroscopy of impurities interacting with a quantum gas at finite temperature. In the limit of a single impurity, we show using Fermi's golden rule that introducing (or injecting) an impurity into the medium is equivalent to ejecting an impurity that is initially interacting with the medium, since the "injection" and "ejection" spectral responses are simply related to each other by an exponential function of frequency. Thus, the full spectral information for the quantum impurity is contained in the injection spectral response, which can be determined using a range of theoretical methods, including variational approaches. We use this property to compute the finite-temperature equation of state and Tan contact of the Fermi polaron. Our results for the contact of a mobile impurity are in excellent agreement with recent experiments and we find that the finite-temperature behavior is qualitatively different compared to the case of infinite impurity mass.

description: Additional file 6: Supplementary Figure 5. Effect of CD16/CD62L-antibodies on neutrophil function. Neutrophil phagocytosis (a) and neutrophil phagosomal acidification (b) in five healthy controls after 60 minutes of incubation with S. Aureus bioparticles. Per patient, this analysis was performed three times in different conditions: 1) with 6 μL Hepes buffer, 2) with 6 μL CD16-BV785 and 3) with 6 μL CD62L-BV650. The Hepes buffer and antibody-fluorochrome combinations were added to the wells plate prior to initiation of the functional analyses to prevent a time delay between the different analyses. The Hepes buffer consisted of 20 mM Hepes, 132 mM NaCl, 6 mM KCl, 1.2 mM KH2PO4 and 1 mM MgSO4, supplemented with 5 mM glucose, 1 mM CaCl2, and 0.5% (w/v) human serum albumin. The CD16/CD62L-antibody-fluorochrome combinations were chosen because the fluorochromes are not excited by the 488 laser of the AQUIOS CL® “Load & Go” flow cytometer. A Friedman test was used to compare the three different conditions. No significant differences in neutrophil phagocytosis and neutrophil phagosomal acidification were found after the addition of CD16 and CD62L antibodies. Data are presented as individual values with mean (black line). MFI = median fluorescence intensity. PF520 = PromoFluor 520 LSS. S. Aureus = Staphylococcus Aureus. Ns = non-significant.

[Holotype: CASC; ♀ Parker Dam, San Bernardino Co., California, USA; April 22, 1951]
Perdita adustiventris was first described from the southwestern USA and was first reported in the Gulf Coast Region in Isla Angel de La Guarda and the Lower Colorado Desert in Bahia de los Ángeles, BC, México in Timberlake (1971). This species specializes on pollen from plants in the genus Mentzelia L. (Fowler 2020). We confirmed these records by reviewing the specimens at LACM. See fig. 44.

title: Mutational resistance to linezolid and other anti-gram-positive antibiotics in staphylococci
Creators: name: North, Sarah

description: Methicillin-resistant Staphylococcus aureus (MRSA) are endemic in UK hospitals. Treatment options for the infections caused by these multiresistant strains include vancomycin, teicoplanin and linezolid. Mutational resistance to these antibiotics, although rare in the clinic, has been detected. Resistance to linezolid requires at least one chromosomal mutation followed by subsequent internal recombination. The hypothesis tested was that resistance to linezolid or glycopeptides could emerge in hypermutable strains and that hypermutability could be co-selected with resistance to linezolid or glycopeptides. Accordingly, this work studied linezolid and teicoplanin-resistant clinical isolates and laboratory-selected linezolid-resistant S. aureus mutants for evidence of hypermutability.

 Mutation frequencies to a range of antibiotics were determined to evaluate the occurrence of hypermutability. Linezolid-resistant mutants were selected by serial passage in the presence of increasing concentrations of linezolid. Mutations conferring linezolid resistance were characterized by PCR-RFLP and sequencing. Pyrosequencing and hybridization were used to detect and quantify six mutations known to confer linezolid resistance.

 Pre-existing hypermutability increased the ability of a laboratory strain to generate linezolid resistant mutants. However, few clinical linezolid or teicoplanin-resistant isolates or mutants were found to be hypermutable, indicating that stable hypermutability is not a prerequisite for the emergence of these resistances. Likewise, no laboratory-selected linezolid-resistant mutants were hypermutable, demonstrating the lack of co-selection of linezolid resistance with hypermutability. Most linezolid-resistant laboratory-selected mutants were unstable. There was a direct correlation between the number of mutated 23 S rRNA genes and linezolid MIC in clinical and laboratory mutants, although analysis was complicated by the fact that the 23S rRNA gene copy number was variable among the laboratory mutants. Cross-resistance between linezolid and chloramphenicol was detected in some laboratory mutants.

 In conclusion, there was no evidence for the co-selection of hypermutability and linezolid or teicoplanin resistance, and hypermutability was not found to be a prerequisite for the emergence of linezolid resistance.
