Constraints on the Baryonic Compression and Implications for the Fraction of Dark Halo Lenses
Creators: name: Oguri, Masamune
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We predict the fraction of dark halo lenses, that is, the fraction of lens systems produced by the gravitational potential of dark halos, on the basis of a simple parametric model of baryonic compression. The fraction of dark halo lenses primarily contains information on the effect of baryonic compression and the density profile of dark halos, and is expected to be insensitive to cosmological parameters and source population. The model we adopt comprises the galaxy formation probability p_g(M) which describes the global efficiency of baryonic compression and the ratio of circular velocities of galaxies to virial velocities of dark halos gamma_v=v_c/v_{vir} which means how the inner structure of dark halos is modified due to baryonic compression. The model parameters are constrained from the velocity function of galaxies and the distribution of image separations in gravitational lensing, although the degeneracy between model parameters still remains. We show that the fraction of dark halo lenses depends strongly on gamma_v and the density profile of dark halos such as inner slope alpha. This means that the observation of the fraction of dark halos can break the degeneracy between model parameters if the density profile of dark halo lenses is fully settled. On the other hand, by restricting gamma_v to physically plausible range we can predict the lower limit of the fraction of dark halo lenses on the basis of our model. Our result indicates that steeper inner cusps of dark halos (alpha >~ 1.5) or too centrally concentrated dark halos are inconsistent with the lack of dark halo lenses in observations.

Back to the Origin: Elastic Spacetime Model as an Alternative to Gravitation and Dark Components
Creators: name: Aliyev, Khatai
Publisher: name: Zenodo
Year: 2025
Subjects: Gravity, Spacetime, Elastic structure, Quantum vacuum, Black hole, Dark energy, General relativity, Alternative gravity model

description: This paper proposes a new interpretation of gravity based on an elastic spacetime model. Instead of treating gravity as a force, it defines it as the result of a local deformation within a quantum oscillatory vacuum structure. The model addresses inconsistencies in current physics, including singularities, the role of dark matter and energy, and galactic dynamics. It offers a unified, intuitive framework compatible with both general relativity and quantum theory, providing an alternative vision for cosmic structure and interaction.

description: General topologically invariant microscopical expressions for quantum numbers of particle-like solitons ("skyrmions") are derived for a class of (2+1)D models. Skyrmions are either half-integer spin fermions with odd electric charge or integer spin bosons with even charge. So they cannot be Anderson's spinons or holons. General results are exemplified by a square lattice model reminiscenting high-Tc models.
description: LaTeX 2.09, 3 pages, no figures. This paper was published in 1989, but cond-mat/9610040 recently brought the subject of the Hopf term into prominence again. The paper is posted "as published", only the citations "to be published" are replaced by the references. Some discussion is dated, but the relations between the Hopf term, the Hall conductivity, the electric charge of the skyrmion, and the topological invariants in the momentum space are valid and relevant

description: To describe the 5 years’ trajectories in functionality and pain of patients with hip or knee osteoarthritis and arthroplasty and analyze the association of these with long-term patients survival. Patients with OA receiving total hip or knee arthroplasty were recruited and completed two sets of standardized questionnaires for functionality and pain 6, 12, and 60 months postoperatively. Multivariate mixed models were conducted to assess trajectories over time and the resulting improvement per month during the last time period was included in a landmark-model to estimate adjusted hazard ratios for mortality. In total 809 patients with joint replacement were included (mean age 65.0 years, 62.2% female), 407 patients died (median follow-up 18.4 years). Both instruments of functionality and pain showed extensive improvement during the first 6 months. Baseline and change in functionality (both p < 0.001) and pain (p = 0.02) during the first 6 months were associated with mortality. Better values in functionality corresponded with improved survival whereas the association with the pain scores was inverse. In patients with hip and knee OA, an explicit improvement in function is seen within the first 6 months after arthroplasty. In addition, especially the functionality scores at baseline as well as their improvement showed an association with long-term patient survival.

description: Background: Traumatic cervical spinal cord injuries (SCIs) can be lethal and are especially dangerous for older adults. Falls from standing and risk factors for a cervical fracture and spinal cord injury increase with age. This study estimates the 1-year mortality for patients with a cervical fracture and resultant SCI and compares the mortality rate with that from an isolated cervical fracture. Methods: We performed a retrospective cohort study of U.S. Medicare patients older than 65 years of age. International Classification of Diseases (ICD)-9 codes were used to identify patients with a cervical fracture without SCI and patients with a cervical fracture with SCI between 2007 and 2014. Our primary outcome was 1-year mortality cumulative incidence rate; our secondary outcome was the cumulative incidence rate of surgical intervention. Propensity weighted analysis was performed to balance covariates between the groups. Results: The SCI cohort had a 1-year mortality of 36.5%, compared with 31.1% in patients with an isolated cervical fracture (risk difference 5.4% (2.9%–7.9%)). Patients with an SCI were also more likely to undergo surgical intervention compared with those without a SCI (23.1% and 10.3%, respectively; risk difference 12.8% (10.8%-14.9%)). Conclusions: Using well-adjusted population-level data in older adults, this study estimates the 1-year mortality after SCI in older adults to be 36.5%. The mortality after a cervical fracture with SCI was 5 percentage points higher than in patients without SCI, and this difference is smaller than one might expect, likely representing the frailty of this population and unmeasured covariates.

description: Context: The study of dust emission at millimeter wavelengths is important to shed light on the dust properties and physical structure of pre-stellar cores, the initial conditions in the process of star and planet formation. Aims: Using two new continuum facilities, AzTEC at the LMT and MUSTANG-2 at the GBO, we aim to detect changes in the optical properties of dust grains as a function of radius for the well-known pre-stellar core L1544. Methods: We determine the emission profiles at 1.1 and 3.3 mm and examine whether they can be reproduced in terms of the current best physical models for L1544. We also make use of various tools to determine the radial distributions of the density, temperature, and the dust opacity in a self-consistent manner. Results: We find that our observations cannot be reproduced without invoking opacity variations. With the new data, new temperature and density profiles, as well as opacity variations across the core, have been derived. The opacity changes are consistent with the expected variations between uncoagulated bare grains, toward the outer regions of the core, and grains with thick ice mantles, toward the core center. A simple analytical grain growth model predicts the presence of grains of ~3-4 um within the central 2000 au for the new density profile.

description: We present an analysis of nine years of Catalina Surveys optical photometry for 1.4 million spectroscopically confirmed SDSS galaxies. We find 717 outburst events that were not reported by ongoing transient surveys. These events have timescales ranging from weeks to years. More than two thirds of these new events are found in starforming galaxies, while such galaxies only constitute ~20% of our sample. Based on the properties of the hosts and events, we find that almost all of the new events are likely to be associated with regular supernovae. However, a small number of long-timescale events are found among the galaxies containing AGN. These events have similar properties to those recently found in the analyses of light curves of large samples of AGN. Given the lack of such events among the more than a million passive galaxies in the sample, we suggest that the long outbursts are associated with super-massive black holes or their environments.

description: Colloidal dispersions of lipids, e.g. triglycerides, are under intensive investigation as drug delivery systems. Solid
triglyceride nanoparticles exist in different polymorphic modifications. The aim of this study was to investigate the effects
of the addition of glycerol, which can be used for the isotonization of such dispersions, on the polymorphic behavior of
poly(vinyl alcohol)-stabilized tripalmitin nanoparticles. Glycerol was added to the nanoparticle dispersions at different
concentrations in the heat.

The dispersions were investigated for their thermal behavior and storage stability with regard to particle size and
polymorphic transitions of the triglyceride matrix, using photon correlation spectroscopy, differential scanning
calorimetry and X-ray diffraction. The addition of glycerol led to a decreasing crystallization temperature of the
nanoparticles and slowed down the polymorphic transition into the stable β-modification.

description: After Helmholtz, the mechanical foundation of thermodynamics included the First Law $d E = δQ + δW$, and the first part of the Clausius heat theorem $δQ^\text{rev}/T = dS$. The resulting invariance of the entropy $S$ for quasistatic changes in thermally isolated systems invites a connection with Noether's theorem (only established later). In this quest, we continue an idea, first brought up by Wald in black hole thermodynamics and by Sasa $\textit{et al.}$ in various contexts. We follow both Lagrangian and Hamiltonian frameworks, and emphasize the role of Killing equations for deriving a First Law for thermodynamically consistent trajectories, to end up with an expression of ``heat over temperature'' as an exact differential of a Noether charge.

Quantum Field Theory in a Topology Changing Universe

description: We propose a method to construct quantum theory of matter fields in a topology changing universe. Analytic continuation of the semiclassical gravity of a Lorentzian geometry leads to a non-unitary Schrödinger equation in a Euclidean region of spacetime, which does not have a direct interpretation of quantum theory of the Minkowski spacetime. In this Euclidean region we quantize the Euclidean geometry, derive the time-dependent Schrödinger equation and find the quantum states using the Liouville-Neumann method. The Wick rotation of these quantum states provides the correct Hilbert space of matter field in the Euclidean region of the Lorentzian geometry. It is found that the direct quantization of a scalar field in the Lorentzian geometry involves an unusual commutation rule in the Euclidean region. Finally we discuss the interpretation of the periodic solution of the semiclassical gravity equation in the Euclidean geometry as a finite temperature solution for the gravity-matter system in the Lorentzian geometry.

description: We study the dynamics of the solar basin -- the accumulated population of weakly-interacting particles on bound orbits in the Solar System. We focus on particles starting off on Sun-crossing orbits, corresponding to initial conditions of production inside the Sun, and investigate their evolution over the age of the Solar System. A combination of analytic methods, secular perturbation theory, and direct numerical integration of orbits sheds light on the long- and short-term evolution of a population of test particles orbiting the Sun and perturbed by the planets. Our main results are that the effective lifetime of a solar basin at Earth's location is $τ_{\rm eff} = 1.20\pm 0.09 \,\mathrm{Gyr}$, and that there is annual (semi-annual) modulation of the basin density with known phase and amplitude at the fractional level of 6.5% (2.2%). These results have important implications for direct detection searches of solar basin particles, and the strong temporal modulation signature yields a robust discovery channel. Our simulations can also be interpreted in the context of gravitational capture of dark matter in the Solar System, with consequences for any dark-matter phenomenon that may occur below the local escape velocity.

description: We study a recently proposed model in which an odd number of agents are competing to be in the minority. The agents have one strategy in hand which is to follow the most recent history. Each agent is also assigned a value p, which is the probability that an agent will follow the trend. Evolution is introduced through the modification of the value of p when the performance of an agent becomes unsatisfactory. We present numerical results for the distribution of p values in the population as well as the average duration between modifications at a given p for different values of the parameters in the model. We also point out the difference between the present model and a slightly modified model in which a strategy is randomly assigned to every agent initially.

description: In this paper we study the Real Gromov-Witten theory of local 3-folds over Real curves. We show that this gives rise to a 2-dimensional Klein TQFT defined on an extension of the category of unorientable surfaces. We use this structure to completely solve the theory by providing a closed formula for the local RGW invariants in terms of representation theoretic data, extending earlier results of Bryan and Pandharipande. As a consequence we obtain the local version of the real Gopakumar-Vafa formula that expresses the connected real Gromov-Witten invariants in terms of integer invariants. In the case of the resolved conifold the partition function of the RGW invariants agrees with that of the SO/Sp Chern-Simons theory.

description: The industrial implementation of whole-cells and enzymes in flow biocatalysis microreactors is essential for the
emergence of a biobased circular economy. Major challenges concern the efficient immobilization of delicate enzymes
inside miniaturized reactors without compromising their catalytic activity. We describe the design and application of four
different immobilization techniques including self-immobilizing whole-cells and purified enzymes on magnetic
microbeads, as well as reactor modules manufactured by 3D printing of bioinks containing thermostable enzymes. To
increase the volumetric activity of our microreactors we furthermore developed and applied self-assembling all-enzyme
hydrogels with cofactor-regenerating capabilities. The resulting reactor formats have excellent operational stability times
of > 14 days and maximum space-time yields of > 450 g product/L-1day-1 paving the way for mild and effective
immobilization techniques of biocatalysts in microfluidic systems.

description: A process yielding water stable chitosan nanofiber mats is described and their significance in the field of biocatalyst
immobilization is proven. Electrospinning was adapted to produce nanofibers from chitosan derivatives bearing
photoreactive arylazide groups. These photoreactive groups of chitosan were then crosslinked by irradiation with
UV-light. This stabilizes the fiber morphology even upon incubation in water and provides an alternative to crosslinking
with harmful chemicals. Applicability of the fiber mats as enzyme immobilization matrix was demonstrated, using
β-D-galactosidase as model enzyme. Although an initial leaching of enzyme was observed, after 40 days of incubation a
significant portion of active enzyme is still present on the fibers. Thus, the fiber mats are suitable matrices to support
enzymes and can revolutionize future enzymatic production processes of e.g. active pharmaceutical ingredients.

(Comp Eff Res. 2013;2013(3):11-20) proposed propensity score (PS) trimming methods as a means to improve efficiency (Crump) or reduce confounding (Stürmer and Walker). We generalized the trimming definitions by considering multinomial PSs, one for each treatment, and proved that these proposed definitions reduce to the original binary definitions when we have only 2 treatment groups. We then examined the performance of the proposed multinomial trimming methods in the setting of 3 treatment groups, in which subjects with extreme PSs more likely had unmeasured confounders. Inverse probability of treatment weights, matching weights, and overlap weights were used to control for measured confounders. All 3 methods reduced bias regardless of the weighting methods in most scenarios. Multinomial Stürmer and Walker trimming were more successful in bias reduction when the 3 treatment groups had very different sizes (10:10:80). Variance reduction, seen in all methods with inverse probability of treatment weights but not with matching weights or overlap weights, was more successful with multinomial Crump and Stürmer trimming. In conclusion, our proposed definitions of multinomial PS trimming methods were beneficial within our simulation settings that focused on the influence of unmeasured confounders.

description: Premix membrane emulsification is a promising method to produce colloidal lipid carrier systems, e.g. triglyceride
nanoemulsions, with small particle sizes and narrow particle size distributions for intravenous administration. The
stability of these systems can be affected by Ostwald ripening. The process of Ostwald ripening in emulsions of
medium chain triglycerides stabilized with sucrose laurate was monitored by particle size measurements with photon
correlation spectroscopy. Two different preparation methods were used and the concentration of free emulsifier
measured to learn more about the influencing parameters.

The concentration of free sucrose laurate turned out to be the main influencing parameter and should be about zero to
minimize Ostwald ripening in the emulsions.

Statistics and Scaling in Disordered Mesoscopic Electron Systems

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: This review is intended to give a pedagogical and unified view on the subject of the statistics and scaling of physical quantities in disordered electron systems at very low temperatures. Quantum coherence at low temperatures and randomness of microscopic details can cause large fluctuations of physical quantities. In such mesoscopic systems a localization-delocalization transition can occur which forms a critical phenomenon. Accordingly, a one-parameter scaling theory was formulated stressing the role of conductance as the (one-parameter) scaling variable. However, the notion of an order parameter was not fully clarified in this theory. Based on presently available analytical and numerical results we focus here on the description of the total distribution functions and their flow with increasing system size. Still, one-parameter scaling theory does work in terms of typical values of the local density of states and of the conductance which serve as order parameter and scaling variable of the localization-delocalization transition, respectively. Below a certain length scale, $ξ_c$, related to the value of the typical conductance, local quantities are multifractally distributed. This multifractal behavior becomes universal on approaching the localization-delocalization transition with $ξ_c$ playing the role of a correlation length.

description: Substances extracted from Cannabis varieties are of increasing interest, especially cannabidiol as a non-psychoactive
drug with various pharmacological effects. Formulation of cannabidiol is, however, challenging due to its low water
solubility. In this study, different types of lipid carriers were investigated as formulation options for cannabidiol to enable
parenteral or oral application.

The study included self-dispersing lipid formulations, nanoemulsions and liposomes. With regard to parenteral
application, a higher load of cannabidiol was obtained in nanoemulsions than in liposomes. Lipid nanoemulsions are thus
a very promising formulation option for parenteral formulations with a high drug load. Also in formulations intended for
oral use a notably higher amount of cannabidiol could be incorporated in oil-containing self-dispersing formulations than
in liposomes.

description: Background: Anxiety disorders are one of the most common mental illnesses in children and associated with high healthcare utilization. We aimed to estimate 2-year cumulative incidence of mental health–related hospitalizations, treated self-harm, and emergency room (ER) visits in children newly diagnosed with anxiety disorders and, for context, in children without anxiety disorders. Methods: We identified commercially insured treatment naïve children (3–17 years) with a new office-based anxiety disorder diagnosis (ICD-9-CM) from 2005–2014 in the MarketScan claims database. We followed children for up to 2 years after diagnosis for the first of each event: mental health–related hospitalization, inpatient, treated self-harm, and ER visits (any, anxiety-related, injury-related). Children without anxiety diagnoses were included as comparators, matched on age, sex, date, and region. We estimated cumulative incidence of each event using Kaplan–Meier analysis. Results: From 2005–2014, we identified 198,450 children with a new anxiety diagnosis. One-year after anxiety diagnosis, 2.0% of children had a mental health–related hospitalization, 0.08% inpatient, treated self-harm, 1.4% anxiety-related ER visit, and 20% any ER visit; incidence was highest in older children with baseline comorbid depression. One-year cumulative incidence of each event was lower in the comparison cohort without anxiety (e.g., mental health–related hospitalizations = 0.5%, treated self-harm = 0.01%, and ER visits = 13%). Conclusions: Given the prevalence of anxiety disorders, 2-year incidence estimates translate to a significant number of children experiencing each event. Our findings offer caregivers, providers, and patients information to better understand the burden of anxiety disorders and can help anticipate healthcare utilization and inform efforts to prevent these serious events.

description: This paper establishes a data-driven modeling framework for lean Hydrogen (H2)-air reaction rates for the Large Eddy Simulation (LES) of turbulent reactive flows. This is particularly challenging since H2 molecules diffuse much faster than heat, leading to large variations in burning rates, thermodiffusive instabilities at the subfilter scale, and complex turbulence-chemistry interactions. Our data-driven approach leverages a Convolutional Neural Network (CNN), trained to approximate filtered burning rates from emulated LES data. First, five different lean premixed turbulent H2-air flame Direct Numerical Simulations (DNSs) are computed each with a unique global equivalence ratio. Second, DNS snapshots are filtered and downsampled to emulate LES data. Third, a CNN is trained to approximate the filtered burning rates as a function of LES scalar quantities: progress variable, local equivalence ratio and flame thickening due to filtering. Finally, the performances of the CNN model are assessed on test solutions never seen during training. The model retrieves burning rates with very high accuracy. It is also tested on two filter and downsampling parameters and two global equivalence ratios between those used during training. For these interpolation cases, the model approximates burning rates with low error even though the cases were not included in the training dataset. This a priori study shows that the proposed data-driven machine learning framework is able to address the challenge of modeling lean premixed H2-air burning rates. It paves the way for a new modeling paradigm for the simulation of carbon-free hydrogen combustion systems.

description: The model of the cultured single cell is considered insufficient to explain the physiological regulation taking place at the
organ level. The same is true for the prediction of drug action at the organ level or at the level of the intact organism. For
these reasons 3D cell culture models are in increasing demand. It is thus necessary to develop the instruments to handle
such cell aggregates and organoids in a controlled, precise and gentle manner. Here, a microgripper is presented which is
able to work in aqueous solutions and which is compatible with electrophysiological recordings of the cells immobilized
by it. It was successfully employed to position isolated pancreatic islets and a 3D cell culture model of insulin-secreting
cells, the so-called MIN6-pseudoislet. As required it was possible to measure the membrane potential of cells within these
aggregates without any interference from the microgripper.

description: Importance: Postoperative delirium is associated with decreases in long-term cognitive function in elderly populations. Objective: To determine whether postoperative delirium is associated with decreased long-term cognition in a younger, more heterogeneous population. Design, Setting, and Participants: A prospective cohort study was conducted at a single academic medical center (≥800 beds) in the southeastern United States from September 5, 2017, through January 15, 2018. A total of 191 patients aged 18 years or older who were English-speaking and were anticipated to require at least 1 night of hospital admission after a scheduled major nonemergent surgery were included. Prisoners, individuals without baseline cognitive assessments, and those who could not provide informed consent were excluded. Ninety-day follow-up assessments were performed on 135 patients (70.7%). Exposures: The primary exposure was postoperative delirium defined as any instance of delirium occurring 24 to 72 hours after an operation. Delirium was diagnosed by the research team using the Confusion Assessment Method (CAM). Main Outcomes and Measures: The primary outcome was change in cognition at 90 days after surgery compared with baseline, preoperative cognition. Cognition was measured using a telephone version of the Montreal Cognitive Assessment (T-MoCA) with cognitive impairment defined as a score less than 18 on a scale of 0 to 22. Results: Of the 191 patients included in the study, 110 (57.6%) were women; the mean (SD) age was 56.8 (16.7) years. For the primary outcome of interest, patients with and without delirium had a small increase in T-MoCA scores at 90 days compared with baseline on unadjusted analysis (with delirium, 0.69; 95% CI, -0.34 to 1.73 vs without delirium, 0.67; 95% CI, 0.17-1.16). The initial multivariate linear regression model included age, preoperative American Society of Anesthesiologists Physical Status Classification System score, preoperative cognitive impairment, and duration of anesthesia. Preoperative cognitive impairment proved to be the only notable confounder: when adjusted for preoperative cognitive impairment, patients with delirium had a 0.70-point greater decrease in 90-day T-MoCA scores than those without delirium compared with their respective baseline scores (with delirium, 0.16; 95% CI, -0.63 to 0.94 vs without delirium, 0.86; 95% CI, 0.40-1.33). Conclusions and Relevance: Although a statistically significant association between 90-day cognition and postoperative delirium was not noted, patients with preoperative cognitive impairment appeared to have improvements in cognition 90 days after surgery; however, this finding was attenuated if they became delirious. Preoperative cognitive impairment alone should not preclude patients from undergoing indicated surgical procedures.

description: This paper provides the background, methodology and validation for constructing a representation of the European high-voltage grid, including and above 200 kV, based on public data provided by OpenStreetMap. The model-independent grid dataset is published under the Open Data Commons Open Database (ODbL 1.0) licence and can be used for large-scale electricity as well as energy system modelling. The dataset and workflow are provided as part of PyPSA-Eur -- an open-source, sector-coupled optimisation model of the European energy system. By integrating with the codebase for initiatives such as PyPSA-Earth, the value of open and maintainable high-voltage grid data extends to the global context. By accessing the latest data through the the Overpass turbo API, the dataset can be easily reconstructed and updated within minutes. To assess the data quality, this paper further compares the dataset with official statistics and representative model runs using PyPSA-Eur based on different electricity grid representations.
