description: Magnetars form a special population of neutron stars with strong magnetic fields and long spin periods. About 30 magnetars and magnetar candidates known currently are probably isolated. But the possibility that magnetars are in binaries hasn't been excluded. In this work, we perform spin evolution of neutron stars with different magnetic fields in wind-fed high-mass X-ray binaries and compare the spin period distribution with observations, aiming to find magnetars in binaries. Our simulation shows that some of the neutron stars, which have long spin periods or in wide-separation systems, need strong magnetic fields to explain their spin evolution. This implies that there are probably magnetars in high-mass X-ray binaries. Moreover, this can further provide a theoretical basis for some unclear astronomical phenomena, such as the possible origin of periodic fast radio bursts from magnetars in binary systems.

description: The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV gamma-ray sources in astrophysics. By measuring the energy deposit and the three spatial coordinates of individual gamma-ray scattering points, the location of the source in the sky is inferred with Compton kinematics reconstruction. The angular resolution is determined by the detector's energy and spatial resolutions, as well as by the separation in space between the first and second scattering. The imaging response of LXeGRIT was established with gamma-rays from radioactive sources, during calibration and integration at the Columbia Astrophysics Laboratory, prior to the 2000 balloon flight mission. In this paper we describe in detail the various steps involved in imaging sources with LXeGRIT and present experimental results on angular resolution and other parameters which characterize its performance as a Compton telescope.

description: The traditional nuclear shell model approach is extended to include many-body forces. The empirical Hamiltonian with a three-body force is constructed for the identical nucleons on the 0f7/2 shell. Manifestations of the three-body force in spectra, binding energies, seniority mixing, particle-hole symmetry, electromagnetic and particle transition rates are investigated. It is shown that in addition to the usual expansion of the valence space within the tranditional two-body shell model, the three-body component in the Hamiltonian can be an important part improving the quality of the theoretical approach.

description: We present photometry for globular and open cluster stars observed with the Sloan Digital Sky Survey (SDSS). In order to exploit over 100 million stellar objects with r < 22.5 mag observed by SDSS, we need to understand the characteristics of stars in the SDSS ugriz filters. While star clusters provide important calibration samples for stellar colors, the regions close to globular clusters, where the fraction of field stars is smallest, are too crowded for the standard SDSS photometric pipeline to process. To complement the SDSS imaging survey, we reduce the SDSS imaging data for crowded cluster fields using the DAOPHOT/ALLFRAME suite of programs and present photometry for 17 globular clusters and 3 open clusters in a SDSS value-added catalog. Our photometry and cluster fiducial sequences are on the native SDSS 2.5-meter ugriz photometric system, and the fiducial sequences can be directly applied to the SDSS photometry without relying upon any transformations. Model photometry for red giant branch and main-sequence stars obtained by Girardi et al. cannot be matched simultaneously to fiducial sequences; their colors differ by ~0.02-0.05 mag. Good agreement (< ~0.02 mag in colors) is found with Clem et al. empirical fiducial sequences in u'g'r'i'z' when using the transformation equations in Tucker et al.

description: Temperature-dependent angle-resolved photoemission spectroscopy (ARPES) was carried out on single-crystalline EuB6 samples. By measuring ARPES spectra in an extended Brillouin zone, a B 2p hole pocket centered at the X point is clearly observed, thus proving the semimetallic nature of EuB6. Below the Curie temperature TC, ARPES spectra show two B 2p bands of which separation is due to an exchange interaction between local Eu 4f and itinerant B 2p electrons. The exchange splitting becomes smaller as the temperature increases and disappears well above TC. Additionally, a diffuse structure near the Fermi level survives just above TC. Such behavior is well described by Monte Carlo simulations of a Kondo lattice model, thus supporting the formation of magnetic polarons in EuB6, which accounts for the resistivity upturn near above TC when lowering the temperature.

description: We present multiband optical photometric and spectroscopic observations of an unusual Type II supernova, SN 2018hfm, which exploded in the nearby (d = 34.67 Mpc) dwarf galaxy PGC 1297331 with a very low star-formation rate (0.0270 M yr-1) and a subsolar metallicity environment(~ 0.5 Z). The V-band light curve of SN 2018hfm reaches a peak with value of -18.69+/-0.64 mag, followed by a fast decline(4.42+/-0.13 mag (100d)-1). After about 50 days, it is found to experience a large flux drop (~3.0 mag in V), and then enters into an unusually faint tail, which indicates a relatively small amount of 56Ni synthesized during the explosion. From the bolometric light curve, SN 2018hfm is estimated to have low ejecta mass (~1.3M) and low explosion energy(~10 50 erg) compared with typical SNe II. The photospheric spectra of SN 2018hfm are similar to those of other SNe II, with P Cygni profiles of the Balmer series and metal lines, while at late phases the spectra are characterised by box-like profiles of HU emission, suggesting significant interaction between the SN ejecta and circumstellar matter. These box-like emission features are found to show increasing asymmetry with time, with the red-side component becoming gradually weaker, indicating that dust is continuously formed in the ejecta. Based on the dust-estimation tool damocles, we find that the dust increases from ~10 -6M to 10 -4 - 10 -3 M between +66.7 d and +389.4 d after explosion.

description: Neurons in the nervous system are submitted to distinct sources of noise, such as ionic-channel and synaptic noise, which introduces variability in their responses to repeated presentations of identical stimuli. This motivates the use of stochastic models to describe neuronal behavior. In this work, we characterize an intrinsically stochastic neuron model based on a voltage-dependent spike probability function. We determine the effect of the intrinsic noise in single neurons by measuring the spike time reliability and study the stochastic resonance phenomenon. The model was able to show increased reliability for non-zero intrinsic noise values, according to what is known from the literature, and the addition of intrinsic stochasticity in it enhanced the region in which stochastic resonance is present. We proceeded to the study at the network level where we investigated the behavior of a random network composed of stochastic neurons. In this case, the addition of an extra dimension, represented by the intrinsic noise, revealed dynamic states of the system that could not be found otherwise. Finally, we propose a method to estimate the spike probability curve from in vitro electrophysiological data.

Restorative Justice with Juveniles from the Perspective of Australian Practitioners: A Realist Review

Year: 2024
Subjects: classificationCode: 480507
subject: Youth justice

description: The presence of youth crime requires establishing effective models that move beyond punishment towards prevention and healing. The restorative justice approach is an alternative strategy to consider.This study employed the realistic review approach to answer the question ‘what works (or does not work) for whom, and under what conditions?’ through the identification of Context–Intervention–Mechanism–Outcome configurations, extracted from 31 articles. For this review context describes contextual characteristics of the participants of restorative justice programs and mechanism is defined as an internal response (psychological change) that triggers the transformation in stakeholders and results in preferred outcome. These were formulated into initial middle-range theories (MRTs) that outline how certain mechanisms of intervention work in a specific context to bring about certain outcomes. This review developed five initial MRTs on youth justice conferencing, youth justice committees, Teen Court, Youth Koori Court, and restorative practices in schools.These initial MRTs were then tested and refined to reflect the restorative models practised in Australia, through the conduct of 20 semi-structured realist interviews with Australian practitioners from the youth justice system and schools, and observation of video resources related to youth justice conferences in New South Wales. Although the Youth Koori Court is practised in Australia, this model was excluded from the testing and refining phase because ethical approval to interview stakeholders from the Aboriginal Youth Koori Court was not received.Template analysis was adopted to analyse the interview data and the observation notes, and to develop the initial MRTs into refined MRTs applicable to the Australian context.Findings indicate that restorative justice interventions in the youth justice system and schools activate mechanisms that encourage the development of values in juveniles that result in the self-motivation to engage in pro-social behaviour. This reduces disruptive behaviours, bullying/cyberbullying, victimisation, increases the distance between committed offences, decreases the seriousness of offences, but does not eliminate offending. The triggered mechanisms that caused changes in young persons also strengthened family and community ties and developed social and emotional skills.

Do Temporary Skilled Migrants in the Healthcare Sector in Australia, namely the Nursing Profession, have Agency over their Migration Experience?
Creators: name: Yilmaz, Serap

subject: Labour, migration and development

description: This doctoral research addressed a notable void in the existing literature concerning temporary skilled migrants (TSMs) in the Australian healthcare sector, particularly those holding Temporary Work (Skilled) visas (subclass 457) [457] or Temporary Skills Shortage visas (subclass 482) [TSS], and their agency in shaping their migration experiences. While prior research has explored the economic aspects of skilled migration, the political agency of temporary migrants, and their lived experiences across multiple sectors, a comprehensive investigation into the diverse experiences and agency of TSMs beyond just political agency is lacking.The central aim of this study has been to delve deeply into the agency experienced by these migrants in influencing their life trajectories and contributing to the evolution of Australian migration policy. There is a void in the academic literature documenting the decisions and issues faced by TSMs in the Australian healthcare sector. This research aimed to resolve this significant gap in the literature aimed to emphasise the pivotal role of TSM perspectives to impact upon migration policy in Australia. This qualitative study involved a focus group with six stakeholders from diverse professions connected to TSMs and interviews with eight TSMs on (or previously on) the 457 and/or 482 visas. This study outlined the systemic challenges faced by TSMs across the healthcare sector including inadequate pre- and post-arrival support, cultural awareness deficits, visa renewal uncertainties, age restrictions for permanent residency, and financial burdens. The study outlined TSMs lack of involvement in migration policy processes, leading to pervasive uncertainty and limiting their ability to plan, particularly given the 45-year age limit for permanent residency applicants, and high visa fees forcing TSMs into suboptimal conditions. The findings confirmed that insufficient integration support for TSMs further impedes their ability to fully settle and navigate new systems, as well as the need for policy reforms to empower TSMs and enhance their agency over their migration journeys.Despite their qualifications, skills, and contributions to the host nation's healthcare system, the study found that the systemic constraints and formidable challenges TSMs face overwhelmingly diminish their ability to shape their migration trajectories and exercise genuine agency. This study offered recommendations for reforms that can enhance the participation of TSMs in policymaking processes, therefore improving skilled migration outcomes in Australia.

description: INTRODUCTION: Rural communities often face chronic challenges of high rates of serious health conditions coupled with inadequate access to health care services-challenges exacerbated by the COVID-19 pandemic. One strategy with the potential to mitigate these problems is the increased use of telehealth technology. A feature of telehealth applications-collaboration between health care providers for consultation and other purposes-referred to herein as Rural Provider-to-Provider Telehealth (RPPT), introduces important expertise that may not exist locally in rural communities. Literature indicates that RPPT is operationalized through many methods with an array of purposes. While RPPT is a promising strategy that brings additional expertise to patient-centered rural care delivery, there is limited evidence addressing important considerations, including how patient access and outcomes, provider satisfaction and performance, and payment may be affected by its use.
METHODS: Recognizing the significant potential of RPPT and the need for more information associated with its use, the National Institutes of Health convened a Pathways to Prevention (P2P) workshop to further understand RPPT's effectiveness and impact on improving health outcomes in rural settings. The P2P initiative, supported by several federal health agencies, engaged rural health stakeholders and experts to examine four key questions, identify related knowledge gaps, and provide recommendations to advance understanding of the use and impact of RPPT.
RESULTS: Included in this report is a description of the process used to generate information about RPPT, the identification of key knowledge gaps, and specific recommendations to further build needed evidence.
DISCUSSION: The emerging use of RPPT is an important tool for bridging gaps in access to care that impacts rural populations. However, to fully understand the value and effects of RPPT, new research is needed to fill the knowledge gaps identified in this report. Additionally, this report should help engage providers, payors, and policymakers interested in supporting evidence-informed RPPT practice, policy, and payment, with the ultimate aim of improving access to health care and health status of rural communities in the United States and worldwide.

description: BACKGROUND: To describe reasons for deviations from planned chemotherapy treatments in women with nonmetastatic breast cancer that contribute to less-than-planned receipt of chemotherapy.
METHODS: Electronic medical records for patients receiving chemotherapy were reviewed for adverse events and treatment modifications. Log-binomial regression models were used to estimate relative risks (RRs) with 95% CIs to examine associations between chemotherapy modifications, patient characteristics, and treatment modalities.
RESULTS: Delays in chemotherapy initiation (7%) were for surgical complications (58%), personal reasons (16%), and other (26%; port malfunction, infections, and obtaining extra imaging). Delays during chemotherapy (38%) were for infections (20%), neutropenia (13%), and personal reasons (13%). Dose reductions (38%) were for neuropathy (36%), unknown causes (9%), anemia (9%), and neutropenia (8%). Early treatment discontinuations (23%) were for neuropathy (29%). Patients receiving paclitaxel/nab-paclitaxel (RR 2.05; 95% CI, 1.47-2.87) and an anthracycline (RR 1.89; 95% CI, 1.39-2.57) reported more dose delays during chemotherapy. Black race (RR 1.46; 95% CI, 1.07-2.00), stage 3 (RR 1.79; 95% CI, 1.09-2.93), and paclitaxel/nab-paclitaxel receipt (RR 1.39; 95% CI, 1.02-1.90) increased the likelihood of dose reduction. Both Black race (RR 2.06; 95% CI, 1.35-3.15) and receipt of paclitaxel/nab-paclitaxel (RR 1.93; 95% CI, 1.19-3.13) increased the likelihood of early discontinuation. Patients receiving anthracyclines had higher rates of hospitalizations during chemotherapy (RR: 1.79; 95% CI, 1.11-2.89).
CONCLUSION: Toxicities are the most common reason for treatment modifications and need close monitoring in high-risk groups for timely intervention. Dose reductions and early treatment discontinuations occurred more for Black patients and need further study.

description: BACKGROUND: To describe the surgical technique of non-compressive intramedullary threaded nail (IMTN) fixation of distal ulnar neck fractures and present the clinical and radiographic outcomes of four patients treated with this novel technique.
METHODS: At a single Level 1 Trauma Center, a retrospective review was conducted for patients with distal ulnar neck fractures treated with retrograde IMTN between 2022 and 2024. Exclusion criteria included inadequate follow-up. A single surgeon performed all procedures using percutaneous retrograde IMTN fixation through the central disc of the triangular fibrocartilage complex (TFCC). Patients initiated a range of motion (ROM) protocol two weeks post-operatively. Post-operative radiographic images were used to calculate the ratio of IMTN diameter to the distal ulnar medullary isthmus diameter proximal to the fracture site. Radiographic changes in displacement, angulation, and ulnar variance were calculated between the first and last follow-up radiographs. Functional outcomes including grip strength and ROM were collected.
RESULTS: Four patients with distal ulnar neck fractures were treated with retrograde IMTN between 2022 and 2024. They were followed for a minimum of three months post-operatively. All were female with an average age of 65 years. All distal ulna fractures were associated with operatively treated intraarticular distal radius fractures. All patients were treated with 75 mm length and 4.5 mm diameter IMTNs. IMTN-to-Isthmus ratio was greater than 60% in all cases. Average radiographic displacement and angulation were unchanged at the final follow-up. The average ulnar variance increased by 1.2 mm. At the final follow-up, there were no post-operative complications. No cases demonstrated ulnar-sided wrist pain, nonunion, or required revision surgery.
CONCLUSIONS: Retrograde IMTN fixation is a novel surgical technique for the treatment of distal ulnar neck fractures. We found limited but promising post-operative radiographic and functional outcomes in our patients without reported ulnar-sided wrist pain, nonunion, or need for hardware removal.
Revisiting kinetic Monte Carlo algorithms for time-dependent processes: From open-loop control to feedback control
Creators: name: Lu, Zhiyue
name: Chittari, Supraja S.
Publisher: name: AIP Publishing
Year: 2024

description: Simulating stochastic systems with feedback control is challenging due to the complex interplay between the system's dynamics and the feedback-dependent control protocols. We present a single-step-trajectory probability analysis to time-dependent stochastic systems. Based on this analysis, we revisit several time-dependent kinetic Monte Carlo (KMC) algorithms designed for systems under open-loop-control protocols. Our analysis provides a unified alternative proof to these algorithms, summarized into a pedagogical tutorial. Moreover, with the trajectory probability analysis, we present a novel feedback-controlled KMC algorithm that accurately captures the dynamics systems controlled by an external signal based on the measurements of the system's state. Our method correctly captures the system dynamics and avoids the artificial Zeno effect that arises from incorrectly applying the direct Gillespie algorithm to feedback-controlled systems. This work provides a unified perspective on existing open-loop-control KMC algorithms and also offers a powerful and accurate tool for simulating stochastic systems with feedback control.
Heavy-dense QCD, sign optimization, and Lefschetz thimbles

Publisher: name: American Physical Society (APS)
Year: 2024

description: We study the heavy-dense limit of QCD on the lattice with heavy quarks at high density. The effective three-dimensional theory has a sign problem which is alleviated by sign optimization where the path integration domain is deformed in complex space in a way that minimizes the phase oscillations. We simulate the theory via a hybrid Monte Carlo approach, for different volumes, both to leading order and next-to-next-to leading order in the hopping expansion, and show that sign optimization successfully mitigates the sign problem at large enough volumes where usual reweighting methods fail. Finally we show that there is a significant overlap between the complex manifold generated by sign optimization and the Lefschetz thimbles associated with the theory.
QCD critical point, Lee-Yang edge singularities, and Padé resummations

description: I analyze the trajectory of the Lee-Yang edge singularities of the QCD equation of state in the complex baryon
chemical potential (μB) plane for different values of the temperature by using the recent lattice results for the
Taylor expansion coefficients up to eighth order in μB and various resummation techniques that blend in Padé
expansions and conformal maps. By extrapolating from this information, I estimate for the location of the QCD
critical point: Tc ≈ 100 MeV, μc ≈ 580 MeV. I also estimate the crossover slope at the critical point to be α1 ≈ 9◦
and further constrain the nonuniversal mapping parameters between the three-dimensional Ising model and QCD
equations of state.

description: Polymerized β-actin may provide a structural basis for chromatin accessibility and actin transport into the nucleus can guide mesenchymal stem cell (MSC) differentiation. Using MSC, we show that using CK666 to inhibit Arp2/3 directed secondary actin branching results in decreased nuclear actin structure, and significantly alters chromatin access measured with ATACseq at 24 h. The ATAC-seq results due to CK666 are distinct from those caused by cytochalasin D (CytoD), which enhances nuclear actin structure. In addition, nuclear visualization shows Arp2/3 inhibition decreases pericentric H3K9me3 marks. CytoD, alternatively, induces redistribution of H3K27me3 marks centrally. Such alterations in chromatin landscape are consistent with differential gene expression associated with distinctive differentiation patterns. Further, knockdown of the non-enzymatic monomeric actin binding protein, Arp4, leads to extensive chromatin unpacking, but only a modest increase in transcription, indicating an active role for actin-Arp4 in transcription. These data indicate that dynamic actin remodeling can regulate chromatin interactions.
An analysis of intraovarian sperm interaction in the guppy, Poecilia reticulata
Creators: name: Grove, Bryon Dennis
Publisher: name: University of British Columbia
Year: 2010

description: Although guppy females may store sperm in the ovary for several months, they become sexually receptive for a short time every 22-30 days. Females may remate during these receptive periods and consequently, a potential competition between stored and fresh sperm for oocytes may occur. Earlier studies indicated that sperm from the most recent insemination dominates fertilization of new broods. However, these studies provide no clues to how this apparent sperm precedence occurs. There are three possible explanations. First, sperm from new inseminations may outnumber stored sperm and thus, have a statistical advantage. Second, since fertilization in guppies occurs within a few days of insemination, this timing of insemination (relative to egg maturity) may give fresh sperm an advantage. Finally, the location of fresh sperm in the ovary may give them greater access to mature eggs. In this study, females were artificially inseminated with known numbers of spermatophores to see how the proportion of one male's sperm in a mixed insemination determines its contribution to new broods; 2.) the number of spermatophores in inseminations affects the degree of precedence shown by sperm from re-inseminations; and 3.) the timing of re-insemination relative to the female reproductive cycle affects the degree of precedence shown by re-inseminations. An autosomal, recessive allele was used as a genetic marker to distinguish between different males' sperm. In addition, ovaries of females artificially inseminated twice were examined histologically to locate sperm from each insemination. Sperm from one of the inseminations was radioactively labelled. These experiments indicated that sperm precedence does not necessarily result from a statistical advantage to sperm from a re-insemination. Also sperm from re-inseminations occurring up to a week before a new batch of oocytes is mature have strong precedence over stored sperm, although the degree of precedence may be reduced. Autoradiographical analysis of sections of ovaries, however, indicated that the location of sperm storage sites may contribute to sperm precedence. Sperm clusters found in tubules closely associated with oocytes come predominantly from re-inseminations. A model is proposed suggesting that movement of sperm into these tubules immediately after insemination accounts for the dominance of new inseminations during fertilization. The possible functional significance of sperm storage and sperm precedence in poeciliids is discussed.

description: We study two problems. First, we consider the large deviation behavior of empirical measures of certain diffusion processes as, simultaneously, the time horizon becomes large and noise becomes vanishingly small. The law of large numbers (LLN) of the empirical measure in this asymptotic regime is given by the unique equilibrium of the noiseless dynamics. Due to degeneracy of the noise in the limit, the methods of Donsker and Varadhan [Comm. Pure Appl. Math. 29 (1976), pp. 389–461] are not directly applicable and new ideas are needed. Second, we study a system of slow-fast diffusions where both the slow and the fast components have vanishing noise on their natural time scales. This time the LLN is governed by a degenerate averaging principle in which local equilibria of the noiseless system obtained from the fast dynamics describe the asymptotic evolution of the slow component. We establish a large deviation principle that describes probabilities of divergence from this behavior. On the one hand our methods require stronger assumptions than the nondegenerate settings, while on the other hand the rate functions take simple and explicit forms that have striking differences from their nondegenerate counterparts.

description: For any reductive group G and a parabolic subgroup P with its Levi subgroup L, the first author [9] introduced a ring homomorphism ξ λ P : Rep λ − poly C ( L ) → H ⁎ ( G / P , C ) , where Rep λ − poly C ( L ) is a certain subring of the complexified representation ring of L (depending upon the choice of an irreducible representation V ( λ ) of G with highest weight λ). In this paper we study this homomorphism for G = SO ( 2 n ) and its maximal parabolic subgroups P n − k for any 2 ≤ k ≤ n − 1 (with the choice of V ( λ ) to be the defining representation V ( ω 1 ) in C 2 n ). Thus, we obtain a C -algebra homomorphism ξ n , k D : Rep ω 1 − poly C ( SO ( 2 k ) ) → H ⁎ ( OG ( n − k , 2 n ) , C ) . We determine this homomorphism explicitly in the paper. We further analyze the behavior of ξ n , k D when n tends to ∞ keeping k fixed and show that ξ n , k becomes injective in the limit. We also determine explicitly (via some computer calculation) the homomorphism ξ λ P for all the exceptional groups G (with a specific ‘minimal’ choice of λ) and all their maximal parabolic subgroups except E 8 .

description: Diversification is a strategy adopted by farming households to meet several challenges. However, there is a lack of empirical evidence to support these positions. We contribute to filling this research gap by providing quantitative evidence of the impact of diversification on the additional income of cocoa-producing households. This study aims to analyze income from the diversification strategies of cocoa producers by building the typology of the most common systems and assessing their impacts on household income. A survey of 303 households across five Côte d’Ivoire regions reveals that cocoa producers have four distinct types of production systems, namely: (1) simple cocoa production systems; (2) cocoa production systems with crops in association; (3) cocoa production systems combined with income generating diversification on the additional plot; and (4) cocoa production systems, and food cropland. Of the four systems, type 3 is the most widely adopted by cocoa producers, generating higher income per household than the other types due to the large part of perennial income that requires a larger area. Furthermore, type 2 presents the best cocoa yield. We also assessed differences per population group. Thus, the results show that women adopt type 2 and type 4 systems with less surface area and are more devoted to the production of subsistence crops. Non-Ivorian producers have systems with higher cocoa yields and income from diversification than Ivorian producers. However, only 7% of producers have access to financing enabling them to invest in diversification crops. The findings demonstrate that crop diversification strategies can successfully improve households’ living income and ensure the sustainability of cocoa production.

Testing cosmological structure formation using redshift-space distortions

description: Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure. In this paper we develop and test a new statistic based on anisotropies in the measured galaxy power spectrum, which is independent of galaxy bias and matches the matter power spectrum shape on large scales. The amplitude provides a constraint on the derivative of the linear growth rate through f.sigma_8. This demonstrates that spectroscopic galaxy surveys offer many of the same advantages as weak lensing surveys, in that they both use galaxies as test particles to probe all matter in the Universe. They are complementary as redshift-space distortions probe non-relativistic velocities and therefore the temporal metric perturbations, while weak lensing tests the sum of the temporal and spatial metric perturbations. The degree to which our estimator can be pushed into the non-linear regime is considered and we show that a simple Gaussian damping model, similar to that previously used to model the behaviour of the power spectrum on very small scales, can also model the quasi-linear behaviour of our estimator. This enhances the information that can be extracted from surveys for LCDM models.

description: Breeders work to adapt winter wheat genotypes for high planting densities to pursue sustainable intensification and maximize canopy productivity. Although the effects of plant-plant competition at high planting density have been extensively reported, the quantitative relationship between competitiveness and plant performance remains unclear. In this study, we introduced a shoot competitiveness index (SCI) to quantify the competitiveness of genotypes and examined the dynamics of nine competitiveness-related traits in 200 winter wheat genotypes grown in heterogeneous canopies at two planting densities. Higher planting densities increased shoot length but reduced biomass, tiller numbers, and leaf mass per area (LMA), with trait plasticity showing at least 41% variation between genotypes. Surprisingly, genotypes with higher LMA at low density exhibited greater decreases under high density, challenging expectations from game theory. Regression analysis identified tiller number, LMA, and shoot length as key traits influencing performance under high density. Contrary to our hypothesis, early competitiveness did not guarantee sustained performance, revealing the dynamic nature of plant-plant competition. Our evaluation of breeding progress across the panel revealed a declining trend in SCI (R² = 0.61), aligning with the breeding objective of reducing plant height to reduce individual competitiveness and increase the plant-plant cooperation. The absence of historical trends in functional traits and their plasticities, such as tiller number and LMA, suggests their potential for designing ideal trait-plasticity for plant-plant cooperation and further crop improvement.

description: We report on measurements of the excitation spectrum of a strongly interacting Bose-Einstein condensate (BEC). A magnetic-field Feshbach resonance is used to tune atom-atom interactions in the condensate and to reach a regime where quantum depletion and beyond mean-field corrections to the condensate chemical potential are significant. We use two-photon Bragg spectroscopy to probe the condensate excitation spectrum; our results demonstrate the onset of beyond mean-field effects in a gaseous BEC.

A survey of townhouse owners' preferences for private outdoor space
Creators: name: Greig, Barbara Jean
Publisher: name: University of British Columbia

description: Due to a variety of economic pressures, medium-density housing forms, particularly the townhouse, have become increasingly popular alternatives to detached housing. The design of the communal and private outdoor space in townhouse projects has been criticized for a lack of space and privacy. The objectives of this study were to describe townhouse owners, determine their satisfaction with the project and the size, privacy, and design of back yards, and test whether their evaluations could be predicted from their demographic characteristics, housing background, or their attitudes about housing and the use and design of outdoor space. To satisfy these objectives, interviews were conducted with ninety owners in nine townhouse projects located in the Greater Vancouver area of B.C. The projects were randomly selected from eligible projects in four municipalities and respondents were selected by interviewing residents found at home during the week or on weekends. Factor analysis, cluster analysis, and regression analysis were used to test for predictors of satisfaction. The townhouse owners represented a broad range of ages, incomes, family sizes, and housing backgrounds. Overall satisfaction with the projects and yards was high, and the majority rated privacy as adequate. Regression analysis predicted 25% of the variance in general ratings, 20% of the variance in privacy ratings, and 20% of the variance in ratings of social problems in the projects. All three rating measures were predicted by regressions significant at p=.10. The most useful predictors included the reasons people were living in townhouses, their attitudes about family use of the back yard, and what kind of housing they had lived in. Based on the findings, recommendations were made for the size of yards and patios, privacy fencing, paving materials, lawns, plantings, general site design, and management.
