description: A classical problem in computer vision is to infer a 3D scene representation from few images that can be used to render novel views at interactive rates. Previous work focuses on reconstructing pre-defined 3D representations, e.g. textured meshes, or implicit representations, e.g. radiance fields, and often requires input images with precise camera poses and long processing times for each novel scene. In this work, we propose the Scene Representation Transformer (SRT), a method which processes posed or unposed RGB images of a new area, infers a "set-latent scene representation", and synthesises novel views, all in a single feed-forward pass. To calculate the scene representation, we propose a generalization of the Vision Transformer to sets of images, enabling global information integration, and hence 3D reasoning. An efficient decoder transformer parameterizes the light field by attending into the scene representation to render novel views. Learning is supervised end-to-end by minimizing a novel-view reconstruction error. We show that this method outperforms recent baselines in terms of PSNR and speed on synthetic datasets, including a new dataset created for the paper. Further, we demonstrate that SRT scales to support interactive visualization and semantic segmentation of real-world outdoor environments using Street View imagery.

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: We present a new publicly available code, $\texttt{class_rot}$, which modifies $\texttt{class}$ to enable fast non-perturbative calculation of cosmic microwave background polarization power spectra due to both isotropic and anisotropic polarization rotation from cosmic birefringence. Cosmic birefringence can arise from new parity-violating physics such as axion dark matter with a Chern-Simons coupling to photons or Faraday rotation due to a primordial magnetic field. Constraints on these effects can be obtained by comparing measurements to precise numerical calculations of the polarization power spectra. We describe the implementation of $\texttt{class_rot}$ in terms of both mathematical formalism and coding architecture. We also provide usage examples and demonstrate the accuracy of the code by comparing with simulations.

description: No abstracts are to be cited without prior reference to the author.A SciFish 2000 broadband sonar has been used in experimental tests for fish species identification. The tests have been carried out both on fish swimming in a net cage and in field experiments. Broadband echo recordings (110-190kHz) of cod, saithe and herring have been collected and processed with the aim to establish species-specific spectral signatures. Such signatures are then used for training of an artificial neural network, which gives the basis for species classification as well as for distinguishing between size groups. The results show that useful broadband echo signatures can be established, preferable through controlled experimental measurements, but also when conditions in field situations are favourable. The tests also show that live biological targets as fish, introduce considerable uncertainties in classification signatures, compared to i.e. more rigid targets. Improved correctness of species identification seems possible by adding rather simple classification algoritms to the standard procedure used in the present system.

description: Introduction Pharmacy practice research is essential in generating new insights for improving the therapeutic use of medicines and health outcomes. There is a lack of national or local data on competence in conducting practice-based research among hospital pharmacists in Malaysia. This study aimed at exploring the research background of pharmacists in Miri General Hospital, evaluating their self-perceived competence and confidence as well as barriers in conducting pharmacy practice research. Materials and Methods This was a cross-sectional study on hospital pharmacists practicing in Miri General Hospital using a 64-item adapted questionnaire by AbuBakar et al. Both descriptive and inferential statistical analyses were applied using IBM Statistical Package for Social Sciences, version 21. Results [Refer to Poster]. Discussion / Conclusion A large portion of hospital pharmacists in Miri Hospital self-assessed themselves as lacking competence and confidence in several aspects of research competencies, especially in proposing appropriate study designs and methods as well as in biostatistics. • Our findings reflected low scholarly productivity among pharmacists. It is important to emphasize that researchers are ethically obliged to at least make an attempt to publish or present their research findings. Pharmacy leaders should take initiative to provide supports to pharmacists in overcoming the barriers so that they can actively take part in research in their place of practice. Informal research training programs are recommended to specifically tackle the knowledge and competency insufficiency among hospital pharmacists in conducting pharmacy practice research.

description: Acupuncture is a technique in which practitioners stimulate specific points on the body. Those points, called acupuncture points (or acupoints), anatomically define areas on the skin relative to specific landmarks on the body. However, mapping the acupoints to individuals could be challenging for inexperienced acupuncturists. In this project, we proposed a system to localize and visualize facial acupoints for individuals in an augmented reality (AR) context. This system combines a face alignment model and a hair segmentation model to provide dense reference points for acupoints localization in real-time (60FPS). The localization process takes the proportional bone (B-cun or skeletal) measurement method, which is commonly operated by specialists; however, in the real practice, operators sometimes find it inaccurate due to skill-related error. With this system, users, even without any skills, can locate the facial acupoints as a part of the self-training or self-treatment process.

description: The observational mass-radius relation of main sequence stars with masses between ~0.3 and 1.0 Msun reveals deviations between the stellar radii predicted by models and the observed radii of stars in detached binaries. We generate an accurate physical model of the low-mass eclipsing binary T-Cyg1-12664 in the Kepler mission field to measure the physical parameters of its components and to compare them with the prediction of theoretical stellar evolution models. We analyze the Kepler mission light curve of T-Cyg1-12664 to accurately measure the times and phases of the primary and secondary eclipse. In addition, we measure the rotational period of the primary component by analyzing the out-of-eclipse oscillations that are due to spots. We accurately constrain the effective temperature of the system using ground-based absolute photometry in B, V, Rc, and Ic. We also obtain and analyze V, Rc, Ic differential light curves to measure the eccentricity and the orbital inclination of the system, and a precise Teff ratio. From the joint analysis of new radial velocities and those in the literature we measure the individual masses of the stars. Finally, we use the PHOEBE code to generate a physical model of the system. T-Cyg1-12664 is a low eccentricity system, located d=360+/-22 pc away from us, with an orbital period of P=4.1287955(4) days, and an orbital inclination i=86.969+/-0.056 degrees. It is composed of two very different stars with an active G6 primary with Teff1=5560+/-160 K, M1=0.680+/-0.045 Msun, R1=0.799+/-0.017 Rsun, and a M3V secondary star with Teff2=3460+/-210 K, M2=0.376+/-0.017 Msun, and R2=0.3475+/-0.0081 Rsun. The primary star is an oversized and spotted active star, hotter than the stars in its mass range. The secondary is a cool star near the mass boundary for fully convective stars (M~0.35 Msun), whose parameters appear to be in agreement with low-mass stellar model.

description: No abstracts are to be cited without prior reference to the author.In the Barents Sea, the echo abundance of demersal fish is about 50% higher at day than at night. Three possible reasons are: • Fish hide in the bottom dead zone at night. • Fish target strength changes due to pressure-related swim-bladder changes during vertical migration. • Fish target strength varies due to higher variation in the tilt-angle distribution at night. It is very often claimed that the dead zone is most important. We argue that variation in tilt-angle may also be important.

The observed acoustic density of demersal fish during trawling was compared to that just before and just after trawling. For RV 'G.O.Sars', the echo abundance was on average about 12 % lower before and after trawling than during trawling, and the difference was highly significant and consistent between years. For RV 'Johan Hjort' the average difference was about 1%, which was not significant (Figure 1).

description: The goal of this article is to initiate a discussion on what it takes to claim "there is no new physics at the weak scale," namely that the Standard Model (SM) is "isolated." The lack of discovery of beyond the SM (BSM) physics suggests that this may be the case. But to truly establish this statement requires proving all "connected" BSM theories are false, which presents a significant challenge. We propose a general approach to quantitatively assess the current status and future prospects of establishing the isolated SM (ISM), which we give a reasonable definition of. We consider broad elements of BSM theories, and show many examples where current experimental results are not sufficient to verify the ISM. In some cases, there is a clear roadmap for the future experimental program, which we outline, while in other cases, further efforts -- both theoretical and experimental -- are needed in order to robustly claim the establishment of the ISM in the absence of new physics discoveries.

description: Finite-size scaling at fixed renormalization-group invariant is a powerful and flexible technique to analyze Monte Carlo data at a critical point. It consists in fixing a given renormalization-group invariant quantity to a given value, thereby trading its statistical fluctuations with those of a parameter driving the transition. One remarkable feature is the observed significant improvement of statistical accuracy of various quantities, as compared to a standard analysis. We review the method, discussing in detail its implementation, the error analysis, and a previously introduced covariance-based optimization. Comprehensive benchmarks on the Ising model in two and three dimensions show large gains in the statistical accuracy, which are due to cross-correlations between observables. As an application, we compute an accurate estimate of the inverse critical temperature of the improved O(2) $ϕ^4$ model on a three-dimensional cubic lattice.

description: No abstracts are to be cited without prior reference to the author.Traditionally, collection of acoustic data has been optimised for a single frequency, while requirements for the optimal combination of multifrequency data has been given less attention. Even though data processing improves the ability of the single-frequency data to be combined to some extent, optimal output data cannot be achieved from a system if the input data are of poor quality. Multiple singlefrequency [s(f)] data may be collected in various ways onboard research and fishing vessels. For detailed analysis, the physical and spatial characteristics of acoustic data should be as similar as possible. While direct comparability is impossible in all aspects, ideal data is defined as a reference point for the collection and analysis of multiple s(f) data. Acoustic data from several single frequencies are defined as ideal in this context if they can be used to generate combined frequency [c(f)] data at the same resolution as the original. This requires comparable physical measurements, carried out simultaneously from identical volumes, limited only by the effective range of the higher frequencies. Requirements necessary for recording ideal multi-frequency acoustic data are presented. Consequences of combining acoustic data originating from beams of different widths and separation distances are also analysed and illustrated.

description: It is well known that the Helstrom bound can be improved by generalizing the form of a coherent state. Thus, designing a quantum measurement achieving the improved Helstrom bound is important for novel quantum communication. In the present article, we analytically show that the improved Helstrom bound can be achieved by a projective measurement composed of orthogonal non-standard Schrödinger cat states. Moreover, we numerically show that the improved Helstrom bound can be nearly achieved by an indirect measurement based on the Jaynes-Cummings model. As the Jaynes-Cummings model describes an interaction between a light and a two-level atom, we emphasize that the indirect measurement considered in this article has potential to be experimentally implemented.

description: Quantum Monte Carlo (QMC) simulations constitute nowadays one of the most powerful methods to study strongly correlated quantum systems, provided that no "sign problem" arises. However, many systems of interest, including highly frustrated magnets, suffer from an average sign that is close to zero in standard QMC simulations. Nevertheless, a possible sign problem depends on the simulation basis, and here we demonstrate how a suitable choice of cluster basis can be used to eliminate or at least reduce the sign problem in highly frustrated magnets that were so far inaccessible to efficient QMC simulations. We focus in particular on the application of a two-spin (dimer)-based QMC method to the thermodynamics of the spin-1/2 Shastry-Sutherland model for SrCu$_2$(BO$_3$)$_2$.

description: No abstracts are to be cited without prior reference to the author.There is a current desire to harvest marine resources by managing total marine ecosystems rather than single species of the ecosystems. By means of algorithms applied on high-quality multi-frequency acoustic data, species, or rather acoustic categories, of the ecosystem can be identified. This information may significantly increase the accuracy of acoustic survey estimates of fish and to some extent also for zooplankton. Multi-frequency split beam echo sounders with nearly identical and overlapping acoustic beams have been regularly used in acoustic surveys for fish stock abundance estimation at Institute of Marine Research for the last five years. Calibrated raw data from up to six simultaneously working echo sounders at 18, 38, 70, 120, 200 and 364 kHz was used as input to a stepwise, modular sequence of analysis, like bottom detection, noise quantification and removal, target categorisation and school detection in near real-time. Direct generation of new, synthetic echograms, based upon the measured or modelled relative frequency response of the targets is one of the most useful features of the systems. The result of the categorisation process can be used to show the spatial distribution of different acoustic categories in a single synthetic echogram, or to keep some and remove other acoustic categories in echograms at a single frequency.

description: The low-temperature thermodynamic properties of the frustrated pyrochlore Tb$_{2+x}$Ti$_{2-x}$O$_{7+y}$ have been studied using the single crystal of $x=0.005$ sitting in a long range ordered phase in the $x$-$T$ phase diagram. We observed that the specific heat exhibits a minimum around 2 K and slightly increases on cooling, similar to a Schottky-like anomaly for canonical spin ices. A clear specific-heat peak observed at $T_{\rm c} = 0.53$ K is ascribable to the phase transition to a quadrupolar state, which contributes to a relatively large change in entropy, $S \simeq 2.7$ J K$^{-1}$mol$^{-1}$. However, it is still smaller than $R\ln2$ for the ground state doublet of the Tb ions. The entropy release persists to higher temperatures, suggesting strong fluctuations associated with spin ice correlations above $T_{\rm c}$.

description: Antiferromagnetic materials host pairs of spin-up and spin-down magnons which can be described in terms of a magnonic pseudospin. The close analogy between this magnonic pseudospin systems and that of electronic charge carriers led to the prediction of fascinating phenomena in antiferromagnets. Recently, the associated dynamics of antiferromagnetic pseudospin has been experimentally demonstrated and, in particular, the first observation of the magnon Hanle effect has been reported. We here expand the magnonic spin transport description by explicitly taking into account contributions of finite-spin low-energy magnons. In our experiments we realize the spin injection and detection process by two Platinum strips and investigate the influence of the Pt-strips on the generation and diffusive transport of magnons in films of the antiferromagnetic insulator hematite. For both a 15 nm and a 100 nm thick film, we find a distinct signal caused by the magnon Hanle effect. However, the magnonic spin signal exhibits clear differences in both films. In contrast to the thin film, for the thicker one, we observe an oscillating behavior in the high magnetic field range as well as an additional offset signal in the low magnetic field regime. We attribute this offset signal to the presence of finite-spin low-energy magnons.

description: No abstracts are to be cited without prior reference to the author.The purpose of this work has been to test complementary methods in order to classify marine organisms, with particularly attention to zooplankton and fish. Algorithms to separate fish and zooplankton have been developed and implemented at IMR and at IRD. A novel optimised model framework based on known scattering models are used to classify zooplankton and to separate these from fish. Acoustic data from up to 6 frequencies were collected to test the scattering model framework, while concurrent biological samples from multi-net oblique or horizontal MOCNESS tows, WP2 vertical net hauls and pelagic trawl were also obtained and analysed. Great attention are given on one side to the inter calibration and the comparability of all the frequencies, and to the space and time coherence between the samples collected and the acoustical data which are processed. All algorithms involve zooplankton scattering models, the high-pass ones from Stanton, or the more complex ones like the truncated fluid sphere from Holliday or the DWBA set of models from Chu and Stanton. A set of reliable acoustical and biological data has been chosen in order to proceed to comparisons between the results of the acoustic data processing through the classification algorithms and the results of the biological processing.

description: The X-ray source 2XMM J123103.2+110648 was previously found to show pure thermal X-ray spectra and a ~3.8 hr periodicity in three XMM-Newton X-ray observations in 2003-2005, and the optical spectrum of the host galaxy suggested it as a type 2 active galactic nucleus candidate. We have obtained new X-ray observations of the source, with Swift and Chandra in 2013-2016, in order to shed new light on its nature based on its long-term evolution property. We found that the source could be in an X-ray outburst, with the X-ray flux decreasing by an order of magnitude in the Swift and Chandra observations, compared with the XMM-Newton observations ten years ago. There seemed to be significant spectral softening associated with the drop of X-ray flux (disk temperature kT ~ 0.16-0.2 keV in XMM-Newton observations versus kT~0.09+-0.02 keV in the Chandra observation. Therefore the Swift and Chandra follow-up observations support our previous suggestion that the source could be a tidal disruption event (TDE), though it seems to evolve slower than most of the other TDE candidates. The apparent long duration of this event could be due to the presence of a long super-Eddington accretion phase and/or slow circularization.

Implementation of labor position guides to prevent and resolve labor dystocia related to fetal malposition
Creators: name: Rittenbach, Lauren
Publisher: name: No Publisher Supplied
Year: 2024

description: Purpose of the Project: The most common indication for a primary cesarean birth is labor dystocia, an abnormally slow labor. Strategic positioning of laboring patients has shown to resolve labor dystocia related to fetal malposition, thereby increasing the rate of spontaneous vaginal births and decreasing the length of the first stage of labor. This quality improvement (QI) project provided nurses with evidence-based labor position guides from the nursing education group Bundle Birth Nurses. The guide features pictures of positions to use when repositioning labor patients. The purpose of this QI project was to prevent and resolve labor dystocia related to fetal malposition by use of the guides. Methodology: Nurses were asked to voluntarily use and document the guides when repositioning labor patients. Patients’ labor outcomes within 30 days pre and post implementation of the guides were compared. Data on patients’ mode of birth and length of labor was collected through chart reviews. Inclusion criteria for data collection was limited to nulliparous, singleton, term patients with a vertex fetus being induced into labor; 98 patients met this inclusion criteria. Additionally, an anonymous, multiple choice REDCap survey was sent to nurses via email to help determine how frequently the guides were used. Results: Comparative statistical analyses of patients in the inclusion group did not show a significant difference in mode of birth or length of labor. There was no documentation of the guide in any post implementation charts reviewed. Five nurses completed the survey; they reported using the guide 50-75% of the time. It is unclear if nurses utilized the guides with patients in the inclusion group. Implications for Practice: Implementation of this project did not improve labor outcomes. A larger sample and consistent use of the guides are needed to draw a definitive conclusion about the efficacy of the guides.

description: Substantial impact of bovine viral diarrhea virus (BVDV) on the cattle industries has prompted introduction of organized control programs in many states. These programs primarily focus on identification and removal of persistently infected (PI) cattle, the main source of BVDV transmission. In addition to cattle, BVDV may infect a large number of species within the order Artiodactyla as demonstrated by seropositivity. The white-tailed deer is the most abundant wild ruminant species in North America and BVDV infection has been documented in this species. Recently, experimental inoculation of pregnant white-tailed deer resulted in the birth of a persistently infected fawn. Considering the role of PI cattle in the maintenance of BVDV within cattle populations, PI white-tailed deer that harbor and shed the virus continuously may hamper successful execution of control efforts. The objective of this study was the investigation of interspecific BVDV transmission by cohabitation of PI cattle with pregnant white-tailed deer.

description: We study the dissipative Fermi-Hubbard model in the limit of weak tunneling and strong repulsive interactions, where each lattice site is tunnel-coupled to a Markovian fermionic bath. For cold baths at intermediate chemical potentials, the Mott insulator property remains stable and we find a fast relaxation of the particle number towards half filling. On longer time scales, we find that the anti-ferromagnetic order of the Mott-Néel ground state on bi-partite lattices decays, even at zero temperature. For zero and non-zero temperatures, we quantify the different relaxation time scales by means of waiting time distributions which can be derived from an effective (non-Hermitian) Hamiltonian and obtain fully analytic expressions for the Fermi-Hubbard model on a tetramer ring.

description: Bovine respiratory disease (BRD) is the most costly disease of beef cattle in North America. Mannheimia haemolytica is the most common cause of BRD, but recent work suggests that Pasteurella multocida is increasing in importance. Because P multocida is a commensal inhabitant of the upper respiratory tract, it is generally considered an opportunistic pathogen. However, studies in swine indicated that there may be a limited number of strains associated with disease, suggesting that some are more virulent than others. We hypothesize that similar strain differences exist in cattle. Polymerization chain reaction (PCR) fingerprinting is effective in discriminating between isolates of P multocida, but it has not been validated in bovine isolate.s. Therefore, the purpose of this study was to compare the effectiveness of PCR fingerprinting of P multocida isolates from cases of BRD to more traditional approaches, including whole cell protein (WCP) profiles, outer membrane protein (OMP) profiles and serotyping. The information obtained through these techniques was then used to examine isolate diversity to determine if disease was primarily attributable to a limited number of strains.

description: This article aims to transform the infinite-order Lagrangian density for ghost-free infinite-derivative linearized gravity into non-local. To achieve it, we use the theory of generalized functions and the Fourier transform in the space of tempered distributions $\mathcal{S}^\prime$. We show that the non-local operator domain is not defined on the whole functional space but on a subset of it. Moreover, we prove that these functions and their derivatives are bounded in all $\mathbb{R}^3$ and, consequently, the Riemann tensor is regular and the scalar curvature invariants do not present any spacetime singularity. Finally, we explore what conditions we need to satisfy so that the solutions of the linearized equations of motion exist in $\mathcal{S}^\prime$.

description: We present the results of a study of the stellar and accretion properties of the (almost) complete sample of class II and transitional YSOs in the Lupus I, II, III and IV clouds, based on spectroscopic data acquired with the VLT/X-Shooter spectrograph. Our study combines the dataset from our previous work with new observations of 55 additional objects. We have investigated 92 YSO candidates in total, 11 of which have been definitely identified with giant stars unrelated to Lupus. The stellar and accretion properties of the 81 bona fide YSOs, which represent more than 90% of the whole class~II and transition disc YSO population in the aforementioned Lupus clouds, have been homogeneously and self-consistently derived, allowing for an unbiased study of accretion and its relationship with stellar parameters. The accretion luminosity, Lacc, increases with the stellar luminosity, Lstar, with an overall slope of ~1.6, similar but with a smaller scatter than in previous studies. There is a significant lack of strong accretors below Lstar~0.1Lsun, where Lacc is always lower than 0.01Lstar. We argue that the Lacc-Lstar slope is not due to observational biases, but is a true property of the Lupus YSOs. The logMacc-logMstar correlation shows a statistically significant evidence of a break, with a steeper relation for Mstar<0.2Msun and a flatter slope for higher masses. The bimodality of the Macc-Mstar relation is confirmed with four different evolutionary models used to derive the stellar mass. The bimodal behaviour of the observed relationship supports the importance of modelling self-gravity in the early evolution of the more massive discs, but other processes, such as photo evaporation and planet formation during the YSO's lifetime, may also lead to disc dispersal on different timescales depending on the stellar mass. We also refined the empirical Lacc vs. Lline relationships.
