description: White dwarfs in globular clusters offer additional possibilities to determine distances and ages of globular clusters, provided their spectral types and masses are known. We therefore started a project to obtain spectra of white dwarfs in the globular clusters NGC 6397 and NGC 6752. All observed white dwarfs show hydrogen-rich spectra and are therefore classified as DA. Analysing the multi-colour photometry of the white dwarfs in NGC 6752 yields an average gravity of log g = 7.84 and 0.53 Msolar as the most probable average mass for globular cluster white dwarfs. Using this average gravity we try to determine independent temperatures by fitting the white dwarf spectra. While the stellar parameters determined from spectroscopy and photometry usually agree within the mutual error bars, the low resolution and S/N of the spectra prevent us from setting constraints stronger than the ones derived from the photometry alone. For the same reasons the white dwarf spectra obtained for NGC 6397 unfortunately do not provide an independent distance estimate of sufficient accuracy to distinguish between the long and short distance scale for globular clusters.

description: Prior to the passage of the Occupational Safety and Health Act of 1970, farm and ranch safety efforts placed only minor.emphasis on distinctions between work related and non-work related accidents,/ injuries and illnesses. Direct incentives were not present to encourage such differentation and problems were treated on a worst-first basis. A long-run strategy for reducing occupational injuries and illnesses was not articulated.

description: DH Tau b is a young planetary-mass companion orbiting at a projected separation of 320 AU from its $\sim$2 Myr old host star DH Tau. With an estimated mass of $8-22$ $M_{\rm{Jup}}$ this object straddles the deuterium-burning limit, and might have formed via core or pebble accretion, disk instability, or molecular cloud fragmentation. To shed light on the formation history of DH Tau b, we obtain the first measurement of rotational line broadening for this object using high-resolution (R $\sim$25,000) near-infrared spectroscopy from Keck/NIRSPEC. We measure a projected rotational velocity ($v$sin$i$) of $9.6\pm0.7$ km/s, corresponding to a rotation rate that is between 9-15% of DH Tau b's predicted break-up speed. This low rotation rate is in good agreement with scenarios in which magnetic coupling between the companion and its circumplanetary disk during the late stages of accretion reduces angular momentum and regulates spin. We compare the rotation rate of DH Tau b to published values for other planetary-mass objects with masses between $0.3-20$ $M_{\rm{Jup}}$ and find no evidence of a correlation between mass and rotation rate in this mass regime. Finally, we search for evidence of individual molecules in DH Tau b's spectrum and find that it is dominated by CO and H$_2$O, with no evidence for the presence of CH$_4$. This agrees with expectations given DH Tau b's relatively high effective temperature ($\sim$2300 K).

description: We argue that the equations of motion of quantum field theories in curved backgrounds encode new fundamental black hole thermodynamic relations. We define new entropy variation relations. These `emerge' through the monodromies that capture the infinitesimal changes in the black hole background produced by the field excitations. This raises the possibility of new thermodynamic relations defined as independent sums involving entropies, temperatures and angular velocities defined at every black hole horizon. We present explicit results for the sum of all horizon entropy variations for general rotating black holes, both in asymptotically at and asymptotically anti-de Sitter spacetimes in four and higher dimensions. The expressions are universal, and in most cases add up to zero. We also find that these thermodynamic summation relations apply in theories involving multi-charge black holes.

description: In this work we extend the well-known spectral cover construction first developed by Friedman, Morgan, and Witten to describe more general vector bundles on elliptically fibered Calabi-Yau geometries. In particular, we consider the case in which the Calabi-Yau fibration is not in Weierstrass form, but can rather contain fibral divisors or multiple sections (i.e. a higher rank Mordell-Weil group). In these cases, general vector bundles defined over such Calabi-Yau manifolds cannot be described by ordinary spectral data. To accomplish this we employ well established tools from the mathematics literature of Fourier-Mukai functors. We also generalize existing tools for explicitly computing Fourier-Mukai transforms of stable bundles on elliptic Calabi-Yau manifolds. As an example of these new tools we produce novel examples of chirality changing small instanton transitions. The goal of this work is to provide a geometric formalism that can substantially increase the understood regimes of heterotic/F-theory duality.

description: FUSE and HST/STIS spectra of the dwarf nova WZ Sge, obtained during and following the early superoutburst of July 2001 over a time span of 20 months, monitor changes in the components of the system during its different phases. The synthetic spectral fits to the data indicate a cooling in response to the outburst of about 12,000K, from about 28,000K down to about 16,000K. The cooling time scale tau (of the white dwarf temperature excess) is of the order of about 100 days in the early phase of the cooling period, and increases to about 850 days toward the end of the second year following the outburst. In the present work, we numerically model the accretional heating and subsequent cooling of the accreting white dwarf in WZ Sge. The best compressional heating model fit is obtained for a 1.2 Msun white dwarf accreting at a rate of 9.E-9 Msun/yr for 52 days. However, if one assumes a lower mass accretion rate or a lower white dwarf mass, then compressional heating alone cannot account for the observed temperature decline, and other sources of heating have to be included to increase the temperature of the model to the observed value. We quantitatively check the effect of boundary layer irradiation as such an additional source.

description: Presented at the Multidisciplinary Undergraduate Research Conference on March 8, 2008 in the Irving K. Barber Learning Centre, University of British Columbia. Abstract: Organisms that reside in the intertidal zone are routinely subjected to extreme fluctuations of oxygen levels. To cope with subnormal available oxygen in an environment, organisms must either reduce their metabolic activity, switch to alternate biochemical pathways to generate cellular energy, or use a combination of the two. Using the marine mussel, Mytilus trossulus, in a two-part investigation, the critical oxygen tension (Pcrit) was assessed to determine the point at which the animal could no longer maintain normal metabolic activity. With this information, the metabolic responses were analyzed for the second part of the experiment to gain further insight into how alternate biochemical pathways aid the mussel to overcome prolonged oxygen deprivation.

description: This policy position paper is based on the discussions held during the Joint Conference on 22 October 2024, organized by the Horizon Europe gEneSys and NET4Air projects. The conference highlighted the importance of integrating gender equality and the gender dimension in the research and innovation (R&I) processes related to energy transition and advanced technological innovations (deep tech). Despite the distinct focuses of the two projects—gEneSys on social and gender inequalities in energy transition and NET4Air on air pollution monitoring using deep tech—common ground was found in their shared commitment to ensuring that public investment in innovation contributes to both technological progress and social sustainability. This paper outlines key recommendations for policy actions to address these challenges, foster innovation, and meet the European Union’s gender equality and sustainability goals.
Unified Graphical Summary of Neutrino Mixing Parameters

description: The neutrino mixing parameters are presented in a number of different ways by the various experiments, e.g. SuperKamiokande, K2K, SNO, KamLAND and Chooz and also by the Particle Data Group. In this paper, we argue that presenting the data in terms of $\sin^2 θ$, where $θ$ is the mixing angle appropriate for a given experiment has a direct physical interpretation. For current atmospheric, solar and reactor neutrino experiments, the $\sin^2 θ$'s are effectively the probability of finding a given flavor in a particular neutrino mass eigenstate. The given flavor and particular mass eigenstate varies from experiment to experiment, however, the use of $\sin^2 θ$ provides a unified picture of all the data. Using this unified picture we present a graphical way to represent these neutrino mixing parameters which includes the uncertainties. All of this is performed in the context of the present experimental status of three neutrino oscillations.

description: The Art, Astronomy, Technology and Society (AATS) project is an artscience collaboration which dwells in the inbetweenness layer of scientific understanding of the origins of planets and the embodied, intuited ways of knowing. One of the oldest and at the same time one of the newest concerns of humanity is "How did the Earth and the planets come to be?". Planet formation, an intricate and potentially chaotic process, is also very efficient. Every star harbors at least one planet, as evidenced by the high frequency of exoplanet detections. Planet formation must therefore be a frequent process. Yet, learning about the origins of planets has been difficult. Here I share my experience in the AATS artscience project and discuss the nature of artscience collaborations.

description: Sensitive 5-38 um Spitzer Space Telescope (SST) and ground based 3-5 um spectra of the embedded low mass protostars B5 IRS1 and HH46 IRS show deep ice absorption bands superposed on steeply rising mid-infrared continua. The ices likely originate in the circumstellar envelopes. The CO2 bending mode at 15 um is a particularly powerful tracer of the ice composition and processing history. Toward these protostars, this band shows little evidence for thermal processing at temperatures above 50 K. Signatures of lower temperature processing are present in the CO and OCN- bands, however. The observed CO2 profile indicates an intimate mixture with H2O, but not necessarily with CH3OH, in contrast to some high mass protostars. This is consistent with the low CH3OH abundance derived from the ground based L band spectra. The CO2/H2O column density ratios are high in both B5 IRS1 and HH46 IRS (~35%). Clearly, the SST spectra are essential to study ice evolution in low mass protostellar environments, and to eventually determine the relation between interstellar and solar system ices.

description: Purpose: Orthostatic hypotension (OH) is a common disorder, especially among hospitalised patients. Classic OH is defined as occurring 3 or less minutes of orthostatic stress, and delayed OH as occurring after 3 min of stress. We aimed to compare clinical characteristics and prognosis between inpatients with classic vs. delayed OH. Methods: We performed a retrospective analysis of data from 358 inpatients, aged ≥60 years, who were evaluated for the occurrence of OH at the initial phase of ambulation in four previous prospective studies in our department. Demographic, clinical and prognostic data were compared between patients with (n = 191) vs. without (n = 167) OH, classic (n = 138) vs. delayed (n = 53) OH and seated (n = 115) vs. standing (n = 76) OH. Results: Demographic characteristics, duration of bed rest, the main reasons for admission and the use of offending medications were comparable between the delayed and classic OH groups. Mean maximal postural diastolic (p p = .063) blood pressure falls were higher among patients with classic v. delayed OH. No statistically significant difference between the patients with classic and delayed OH were observed in the occurrence of OH-related symptoms (62.3 vs. 69.8%, p = .42). During a median follow-up of 5.5 years, no statistically significant differences in survival were observed between patients with vs. without OH (p = .14), classic vs. delayed OH (p = .68) and seated vs. standing OH (p = .067). On multivariate analysis, these variables remained not significantly associated with decreased survival. Conclusions: Among inpatients, delayed OH is associated with a lesser magnitude of orthostatic blood pressure fall than classic OH. However, rates of symptomatic OH and long-term mortality were comparable between the groups. Thus, among hospitalised patients, delayed OH should be considered as posing the same severity as classic OH.

description: This article focuses on the preservation of landscapes and biodiversity in the low hills of Karakalpakstan, the optimization of nature management, and the inventory of certain insect groups, especially in desert regions with strong anthropogenic influences. The current status of the insect species composition in the region was analyzed, and for the first time, 137 species belonging to 19 orders, 63 families, and 112 genera were identified. Additionally, based on the abundance and density of insects in the region, it was determined that 67 species are permanent or freely living, 29 species are widespread, 4 species are in a state of decline, 23 species are rare, 12 species are very rare, and 2 species are included in the Red Book of the Republic of Uzbekistan.
Rényi Bounds on Information Combining

description: Bounds on information combining are entropic inequalities that determine how the information, or entropy, of a set of random variables can change when they are combined in certain prescribed ways. Such bounds play an important role in information theory, particularly in coding and Shannon theory. The arguably most elementary kind of information combining is the addition of two binary random variables, i.e. a CNOT gate, and the resulting quantities are fundamental when investigating belief propagation and polar coding. In this work we will generalize the concept to Rényi entropies. We give optimal bounds on the conditional Rényi entropy after combination, based on a certain convexity or concavity property and discuss when this property indeed holds. Since there is no generally agreed upon definition of the conditional Rényi entropy, we consider four different versions from the literature. Finally, we discuss the application of these bounds to the polarization of Rényi entropies under polar codes.

description: Using the MOPED algorithm we determine non-parametrically the Stellar Mass Function of 96,545 galaxies from the Sloan Digital Sky Survey data release one. By using the reconstructed spectrum due to starlight we can eliminate contamination from either emission lines or AGN components. Our results give excellent agreement with previous works, but extend their range by more than two decades in mass to 10^{7.5} < M_s/h^{-2}M_\odot < 10^{12}. We present both a standard Schechter fit and a fit modified to include an extra, high-mass contribution, possibly from cluster cD galaxies. The Schechter fit parameters are $ϕ^*=(7.7\pm 0.8)\times 10^{-3} h^3 Mpc^{-3}$, $M^*=(7.53 \pm 0.04) \times 10^{10} h^{-2}M_\odot$ and $α=-1.167\pm 0.004$. Our sample also yields an estimate for the contribution from baryons in stars to the critical density of $Ω_{b*}h=(2.40 \pm 0.04) \times 10^{-3}$, in good agreement with other indicators. Error bars are statistical and a Salpeter IMF is assumed throughout. We find no evolution of the mass function in the redshift range $0.05 < z < 0.34$ indicating that almost all present day stars were already formed at $z \sim 0.34$ with little or no star formation activity since then and that the evolution seen in the luminosity function must be largely due to stellar fading.

description: We consider the effects of on-site and hopping disorder on zero modes in the Su-Schrieffer-Heeger model. In the absence of disorder a domain wall gives rise to two chiral fractionalized bound states, one at the edge and one bound to the domain wall. On-site disorder breaks the chiral symmetry, in contrast to hopping disorder. By using the polarization we find that on-site disorder has little effect on the chiral nature of the bound states for weak to moderate disorder. We explore the behaviour of these bound states for strong disorder, contrasting on-site and hopping disorder and connect our results to the localization properties of the bound states and to recent experiments.

description: Today, there exist many centrality measures for assessing the importance of nodes in a network as a function of their position and the underlying topology. One class of such measures builds on eigenvector centrality, where the importance of a node is derived from the importance of its neighboring nodes. For directed and weighted complex networks, where the nodes can carry some intrinsic property value, there have been centrality measures proposed that are variants of eigenvector centrality. However, these expressions all suffer from shortcomings. Here, an extension of such centrality measures is presented that remedies all previously encountered issues. While similar improved centrality measures have been proposed as algorithmic recipes, the novel quantity that is presented here is a purely analytical expression, only utilizing the adjacency matrix and the vector of node values. The derivation of the new centrality measure is motivated in detail. Specifically, the centrality itself is ideal for the analysis of directed and weighted networks (with node properties) displaying a bow-tie topology. The novel bow-tie centrality is then computed for a unique and extensive real-world data set, coming from economics. It is shown how the bow-tie centrality assesses the relevance of nodes similarly to other eigenvector centrality measures, while not being plagued by their drawbacks in the presence of cycles in the network.

description: This study aims to assist in adopting production practices that lead to better soil health, low plant parasitic nematodes (PPN) population density, increased potato yield for farmers in Western Guatemala using fuzzy cognitive mapping (FCM). A cognitive map was developed representing farmers current perceptions of the production practices and their impacts. In comparison with agricultural professionals cognitive map provided knowledge gaps which will allow agricultural professionals to customize and design more effective technology transfer activities for greater adoption. Primary data were collected in Paquix, Huehuetenango from farmers and at the University of San Carlos in Guatemala from agricultural professionals. Both cognitive maps aligned in general with contrasting perceptions on the impact of certified seeds and compost practices on plant parasitic population density. Training and demonstration plots were perceived as influential to adoption by farmers. Farmers seemed ambiguous on the impact on yield but knowledgeable on the impact on soil health and plant parasitic population density. Most farmers said they receive their information from their local cooperatives and had actively participated in demonstration plots. Understanding the knowledge gaps and knowing where and how farmers got their information, agricultural professionals can effectively design workshops for effective dissemination and thus higher adoption rates.

description: The rise of contract farming is one of the most important changes in modern agriculture. Yet the adoption of these new forms of organization has varied widely across commodities. Vegetable, with more rich varieties compared with other agricultural sections, as the representative of high value agricultural products plays an important role in the development of agricultural economics and the improvement of farmers' income. With the rapid emergence of contract farming in recent decades, China is leading the developing world in vegetable production. By using household survey data, this study aimed to explore the linkage between production attributes of different vegetables and farmers' decision of contract farming participation, as well as examine the impact of marketing contracts on net returns. The results revealed that the harvest and marketing times, perishability, certification of the vegetables, and price fluctuation have significantly positive effect on vegetable farmers contract farming participation, respectively. A propensity score matching (PSM) method is employed to estimate the impact of contract farming on net returns of vegetable production, and find out the effect is insignificant.

description: The resolution of far-field optical microscopes, which rely on propagating optical modes, is widely believed to be limited because of diffraction to a value on the order of a half-wavelength $λ/2$ of the light used. Although immersion microscopes have slightly improved resolution on the order of $λ/2n$, the increased resolution is limited by the small range of refractive indices n of available transparent materials. Here we demonstrate a new far-field optical microscope design, which is capable of reaching nanometer-scale resolution. This microscope uses the fact that the effective refractive index $n_{eff}$ of a planar dielectric lens or mirror placed on a metal surface may reach extremely large values, up to $10^3$, as seen by propagating surface optical modes (plasmons). In our design a magnified planar image produced originally by surface plasmons in the metal plane is viewed by a regular microscope. Thus, the theoretical diffraction limit on resolution is pushed down to nanometer-scale $λ/2n_{eff}$ values. Used in reverse, such a microscope may become an optical lithography tool with nanometer-scale spatial resolution.

description: The magnetorotational instability (MRI) occurs when a weak magnetic field destabilises a rotating, electrically conducting fluid with inwardly increasing angular velocity. The MRI is essential to astrophysical disk theory where the shear is typically Keplerian. Internal shear layers in stars may also be MRI unstable, and they take a wide range of profiles, including near-critical. We show that the fastest growing modes of an ideal magnetofluid are three-dimensional provided the shear rate, $S$, is near the two-dimensional onset value, $S_c$. For a Keplerian shear, three-dimensional modes are unstable above $S\approx0.10S_c$, and dominate the two-dimensional modes until $S\approx2.05S_{c}$. These three-dimensional modes dominate for shear profiles relevant to stars and at magnetic Prandtl numbers relevant to liquid-metal laboratory experiments. Significant numbers of rapidly growing three-dimensional modes remain well past $2.05S_{c}$. These finding are significant in three ways. First, weakly nonlinear theory suggests that the MRI saturates by pushing the shear rate to its critical value. This can happen for systems, like stars and laboratory experiments, that can rearrange their angular velocity profiles. Second, the non-normal character and large transient growth of MRI modes should be important whenever three-dimensionality exists. Finally, three-dimensional growth suggests direct dynamo action driven from the linear instability.

description: This paper tests if Second Price Vickrey Auction (SPVA) and Discrete Choice Experiment (DCE) are isomorphic and whether lack of isomorphism is due to value-elicitation, value-formation or both. We conduct an artefactual field experiment that combines induced-value (IV) and home-grown (HG) procedures using SPVA and DCE. IV preferences are elicited for tokens and HG preferences for multi-attribute lasagnes. Attributes are healthiness and environmental sustainability. Our results suggest that HG preferences differ across elicitation methods. This discrepancy is due to value-elicitation and value-formation. DCE is the most demand-revealing approach and provides the highest premiums for healthy and environmentally sustainable lasagnes. Acknowledgement :

description: We prove that the, appropriately rescaled, boundary of the north polar region in the Aztec diamond converges to the Airy process. The proof uses certain determinantal point processes given by the extended Krawtchouk kernel. We also prove a version of Propp's conjecture concerning the structure of the tiling at the center of the Aztec diamond.
