description: Sr$_{3}$Cr$_{2}$O$_{8}$ consist of a lattice of spin-1/2 Cr$^{5+}$ ions, which form hexagonal bilayers and which are paired into dimers by the dominant antiferromagnetic intrabilayer coupling. The dimers are coupled three-dimensionally by frustrated interdimer interactions. A structural distortion from hexagonal to monoclinic leads to orbital order and lifts the frustration giving rise to spatially anisotropic exchange interactions. We have grown large single crystals of Sr$_{3}$Cr$_{2}$O$_{8}$ and have performed DC susceptibility, high field magnetisation and inelastic neutron scattering measurements. The neutron scattering experiments reveal three gapped and dispersive singlet to triplet modes arising from the three twinned domains that form below the transition thus confirming the picture of orbital ordering. The exchange interactions are extracted by comparing the data to a Random Phase Approximation model and the dimer coupling is found to be $J_{0}=5.55$ meV, while the ratio of interdimer to intradimer exchange constants is $J'/J_{0}=0.64$. The results are compared to those for other gapped magnets.

The role of breastmilk IgA in infant gut microbiota and immune development
Creators: name: Donald, Katherine
Publisher: name: University of British Columbia
Year: 2025

description: The gut microbiota is highly dynamic in the first year of life and plays a pivotal role in immune development. Dysbiosis in the gut microbiota during this period has been linked to later development of numerous immune-mediated diseases, including allergies and asthma, but the specific host-microbe interactions that contribute to this phenomenon are still being uncovered. Secretory IgA (SIgA) is the most abundant antibody in the gut, and a key determinant of gut microbiota composition. During the first months of life, infants are not yet able to produce SIgA, receiving it instead through breastmilk. Breastmilk SIgA is known to protect infants against infections previously encountered by the mother. However, the effects of this antibody on infant gut microbiota composition, and thus immune development, have not been defined. This thesis investigates the role of breastmilk SIgA in guiding microbe-mediated immune imprinting in early life. Chapter 2 uses a mouse model of SIgA deficiency to show that maternal milk SIgA targets and limits the immunostimulatory microbe Segmented Filamentous Bacteria (SFB) in the neonatal murine gut, preventing premature activation of the intestinal Th17 cell responses and protecting against Th17-mediated asthma. Chapter 3 characterizes the human breastmilk SIgA repertoire in mothers enrolled in the CHILD Cohort Study, a longitudinal birth cohort in Canada, demonstrating a relationship between breastmilk SIgA-bacteria binding patterns and infant gut microbiota composition. This chapter identifies the bacterium Erysipelatoclostridium ramosum as an immunologically important target of breastmilk SIgA in the infant gut, and a potential human analogue to the well-studied and disease-relevant mouse pathobiont, SFB. Chapter 4 takes advantage of the techniques developed throughout Chapters 2 and 3 to elucidate the relationship between the maternal gut microbiota, breastmilk SIgA, and bacterial colonization dynamics in the offspring. This chapter confirms the ability of SIgA to mediate mother-to-offspring microbiota transfer. In summary, using in vivo models, human samples, longitudinal human health data, and cell culture, this work defines a significant role for breastmilk SIgA in guiding early-life gut microbiota and immune maturation, with important implications for future developments in preventative medicine and infant nutrition.

description: We developed a new method to extract halo merger rates from the Millennium Simulation. First, by removing superfluous mergers that are artifacts of the FOF halo finder, we find a lower merger rate compared to previous work. The reductions are more significant at lower redshifts, lower halo masses, and minor mergers. Our approach agrees better with predictions from the EPS model. Second, we find that the FOF halo finder overestimates the halo mass by up to 50% for halos that are about to merge, which leads to an additional ~20% overestimate of the merger rate. Therefore, we define halo masses by including only gravitationally bound particles. We provide new best-fitting parameters for a global formula to account for these improvements. In addition, we extract the merger rate per progenitor halo, as well as per descendant halo. The former is the quantity that is related to observed galaxy merger fractions when they are measured via pair counting. At low mass/redshift the merger rate increases with mass and redshift. At high mass/redshift (for halos with masses a few times the "knee" of the mass function) these trends break down, and the merger rate per progenitor halo decreases with mass and increases only moderately with redshift. Defining the merger rate per progenitor halo also allows us to quantify the rate at which halos are being accreted onto larger halos. We provide an analytic formula to convert given merger rates per descendant halo into merger rates per progenitor halo. Finally, we perform a comparison between observed merger fractions and the fraction of halos that have undergone a major merger during the recent dynamical friction time, and find a fair agreement, within the large uncertainties of the observations. Our new halo merger trees are available at http://www.mpe.mpg.de/ir/MillenniumMergerTrees/.

description: For a semisimple factorizable Hopf algebra over a field of characteristic zero, we show that the value that an integral takes on the inverse Drinfel'd element differs from the value that it takes on the Drinfel'd element itself at most by a fourth root of unity. This can be reformulated by saying that the central charge of the Hopf algebra is an integer. If the dimension of the Hopf algebra is odd, we show that these two values differ at most by a sign, which can be reformulated by saying that the central charge is even. We give a precise condition on the dimension that determines whether the plus sign or the minus sign occurs. To formulate our results, we use the language of modular data.

The effects of artisanal and small-scale gold mining on water resources in Afghanistan
Creators: name: Muram, Shahla
Publisher: name: University of British Columbia
Year: 2025

description: Globally, approximately 20 million miners are engaged in gold extraction through Artisanal and Small-Scale Gold Mining (ASGM) which can impact water resources in a variety of ways. This study aims to evaluate ASGM processing methods, specifically alluvial placer and hard rock mining, in Badakhshan, Afghanistan, and to assess the impacts of these mining practices on water resources such as the Kokcha and Sheva Rivers. The research commenced with an extensive literature review conducted across five countries (Ghana, Brazil, Indonesia, Ecuador and Columbia), focusing on the methods employed in various contexts and building an understanding of these activities and their impact on water resources. The research then focused on Badakshan which was supported by ten semi-structured interviews with miners and owners of ASGM companies, through telephone and WhatsApp calls and messaging. Subsequently, ‘pilot’ or ‘pre-evaluation’ calls were conducted with an additional ten local community people and trained mining engineers in Badakhshan to better understand the nature of ASGM work and the protocol for future interviews. This approach seeks to gather insights into localized effects and perspectives and to understand how miners themselves articulate the effects of their activities. The study identifies significant impacts on the Sheva and Kokcha Rivers resulting from ASGM activities, which generate substantial quantities of tailings and liquid slurry composed of crushed rock, water, trace metals, and unspecified minerals. While the scale of these operations may appear small, they have the potential to significantly affect water quality and quantity in the long term. This research enhances the understanding and documentation of ASGM practices in Badakhshan, Afghanistan, raises public awareness of the potential consequences of ASGM activities on water resources, and provides a valuable reference for future studies. Furthermore, Afghanistan currently lacks a cohesive policy on water supply and industrial water usage, and the absence of relevant laws and regulations exacerbates the situation. There is no established guidance or policy governing water use in any industrial sector, particularly in mineral processing.

description: With the increasing prevalence of illicit drugs, social security and human health are at serious risk. However, traditional detection techniques require a lengthy pretreatment process to eliminate matrix interference and do not allow rapid, in situ analysis. Ambient ionization is a powerful tool for the rapid determination of illicit drugs in different matrices because it usually eliminates the need for sample pretreatment, and the portable mass spectrometer brings convenience to in situ detection. This study employed a thermal desorption-electrospray ionization (TD-ESI) source combined with a portable mass spectrometer to rapidly characterize illicit drugs in drinks, instant powders, and solid food surfaces. Air was utilized instead of nitrogen as the carrier gas for TD-ESI/MS in order to save space and cost together with rapid on-site analysis. A full-scan waveform combined with a qualitative pre-scan waveform (QPSW) was employed to form a two-step scanning mode to accurately identify the drugs. The results showed that the limits of detection (LODs) for the analytes were 100–200 ppb in drinks, 700–1000 ppb in instant powders, and 1 ng/cm2 on solid food surfaces. The complete TD-ESI/MS analysis time was less than 1 min.

description: We apply a conventional accretion disk model to the FU Ori-type objects HBC 722 and Gaia 17bpi. Our base model is a steady-state, thin Keplerian disk featuring a modified Shakura-Sunyaev temperature profile, with each annulus radiating as an area-weighted spectrum given by a NextGen atmosphere at the appropriate temperature. We explore departures from the standard model by altering the temperature distribution in the innermost region of the disk to account for "boundary region"-like effects. We consider the overall spectral energy distribution (SED) as well as medium- and high-resolution spectra in evaluating best-fit models to the data. Parameter degeneracies are studied via a Markov Chain Monte Carlo (MCMC) parameter estimation technique. Allowing all parameters to vary, we find accretion rates for HBC 722 of $\dot{M} = 10^{-4.90} M_\odot \textrm{ yr}^{-1}\; {}^{+0.99}_{-0.40} \textrm{ dex}$ and for Gaia 17bpi of $\dot{M} = 10^{-6.70} M_\odot \textrm{ yr}^{-1}\; {}^{+0.46}_{-0.36} \textrm{ dex}$; the corresponding maximum disk temperatures are $7100_{-500}^{+300}$ K and $7900_{-400}^{+900}$ K, respectively. While the accretion rate of HBC 722 is on the same order as other FU Ori-type objects, Gaia 17bpi has a lower rate than previously reported as typical, commensurate with its lower luminosity. Alternate models that fix some disk or stellar parameters are also presented, with tighter confidence intervals on the remaining fitted parameters. In order to improve upon the somewhat large credible intervals for the $\dot{M}$ values, and make progress on boundary layer characterization, flux-calibrated ultraviolet spectroscopy is needed.

description: The potential of multi-walled carbon nanotubes (MWCNTs) in inducing airway hyperresponsiveness (AHR) was investigated in human airways. Human isolated bronchi were exposed to MWCNTs and the contractility to electrical field stimulation (EFS) was measured. Neuronal acetylcholine (ACh) and cyclic adenosine monophosphate (cAMP) were quantified. Some tissues were desensitized by consecutive administrations of capsaicin. MWCNTs (100 ng/ml – 100 µg/ml) induced AHR (overall contractile tone vs. negative control: +83.43 ± 11.13%, P 3Hz) then at medium-to-high frequencies (EFS10Hz and EFS25Hz) (delta potency: +2.13 ± 0.74 and +2.40 ± 0.65 logarithms, respectively). In capsaicin-desensitized airways, the AHR to MWCNTs 100 ng/ml was abolished. MWCNTs increased the release of ACh, an effect prevented by capsaicin-desensitization (−90.17 ± 18.59%, P MWCNTs administered at low concentrations elicit AHR in human airways by activating sensory C-fibers and, in turn, increasing the release of neuronal ACh. Our results suggest that work is required to understand the impact of MWCNTs in patients at risk of AHR, such as those suffering from chronic obstructive respiratory disorders.

description: This talk summarizes the first calculation of the next-to-leading-order electroweak corrections to W-boson + jet hadroproduction including leptonic W-boson decays [1]. The W-boson resonance is treated consistently using the complex-mass scheme, and all off-shell effects are taken into account. The corresponding next-to-leading-order QCD corrections have also been recalculated. All the results are implemented in a flexible Monte Carlo code. Selected numerical results for this Standard Model benchmark process are presented for the LHC.

description: Introduction: INTELLiVENT–Adaptive Support Ventilation (INTELLiVENT–ASV), an advanced closed–loop ventilation mode for use in intensive care unit (ICU) patients, is equipped with algorithms that automatically adjust settings on the basis of physiologic signals and patient’s activity. Here we describe its effectiveness, safety, and efficacy in various types of ICU patients. Areas covered: A systematic search conducted in MEDLINE, EMBASE, the Cochrane Central register of Controlled Trials (CENTRAL), and in Google Scholar identified 10 randomized clinical trials. Expert opinion: Studies suggest INTELLiVENT–ASV to be an effective automated mode with regard to the titrations of tidal volume, airway pressure, and oxygen. INTELLiVENT–ASV is as safe as conventional modes. However, thus far studies have not shown INTELLiVENT–ASV to be superior to conventional modes with regard to duration of ventilation and other patient–centered outcomes. Future studies are needed to test its efficacy.

description: We perform two-dimensional MHD simulations on the solar flux emergence. We set the initial magnetic flux sheet at z=-20,000 km in the convection zone. The flux sheet rises through the convective layer due to the Parker instability, however, decelerates beneath the photosphere because the plasma on the flux sheet piles up owing to the convectively stable photosphere above. Meanwhile, the flux sheet becomes locally unstable to the Parker instability within the photosphere, and the further evolution to the corona occurs (two-step emergence model). We carry out a parameter survey to investigate the condition for this two-step model. We find that magnetic fluxes which form active regions are likely to have undergone the two-step emergence. The condition for the two-step emergence is 10^21 - 10^22 Mx with 10^4 G at z=-20,000 km in the convection zone.

Fast electromagnetic response of a thin film of resonant atoms with permanent dipole

description: We consider the propagation of extremely short pulses through a dielectric thin film containing resonant atoms (two level atoms) with permanent dipole. Assuming that the film width is less than the field wave length, we can solve the wave equation and reduce the problem to a system of generalized Bloch equations describing the resonant atoms. We compute the stationary solutions for a constant irradiation of the film. Superimposing a small amplitude linear wave we compute the reflection and transmission coefficients. From these, one can then deduce the different parameters of the model. We believe this technique could be used in experiments to obtain the medium atomic and relaxation parameters.
Combined Constraints on Holographic Bosonic Technicolor

description: We consider a model of strong electroweak symmetry breaking in which the expectation value of an additional, possibly composite, scalar field is responsible for the generation of fermion masses. The dynamics of the strongly coupled sector is defined and studied via its holographic dual, and does not correspond to a simple, scaled-up version of QCD. We consider the bounds from perturbative unitarity, the S parameter, and the mass of the Higgs-like scalar. We show that the combination of these constraints leaves a relatively limited region of parameter space viable, and suggests the qualitative features of the model that might be probed at the LHC.

description: In this work, twenty-eight novel 17a-aza-D-homo-androster-17-one derivatives, which divided into two categories, were synthesized with commercial available starting material (dehydroepiandrosterone) via oximation reaction, Beckmann rearrangement, hydroxyl protection, N-alkylation and deprotection. All compounds were characterized by 1H NMR, 13C NMR and HRMS. The structure of 14 g was also identified by X-ray single crystal diffraction. The bioactivities, brine shrimp toxicity and cytotoxicity, of all derivatives were tested. The results indicated that compounds 11 h, 11i, 11 m, 11 s, 14 b and 14 g exhibited excellent toxicity against brine shrimp with LC50 values ranging from 5.34 to 16.89 μg/mL, and compounds 11 s and 14 g displayed significant cytotoxicity against HT29 cells and A549 cells with IC50 values of 9.70 μM and 8.85 μM, respectively. Structure-activity relationships are discussed based on the results obtained from our research, and some important determinants for further modification of steroids towards the development of novel drug candidates are identified.

description: Background: Different scoring systems (A2DS2, AISAPS, ISAN) have been designed to predict the risk of in-hospital stroke-associated pneumonia (SAP). Studies have assessed the accuracy of these scores for predicting SAP. We performed this meta-analysis to consolidate the evidence on the predictive accuracies for SAP of the A2DS2, AISAPS, and ISAN scores. Materials and methods: We conducted a systematic search for all studies reporting the SAP predictive accuracy of A2DS2, AISAPS, or ISAN scores in the databases of PubMed Central, SCOPUS, MEDLINE, Embase, and Cochrane from inception until December 2020. We used the STATA software for the meta-analysis. Results: We included 19 studies with 35 849 patients. The pooled score sensitivities were 78% (95% CI, 71%-83%) for A2DS2, 79% (95% CI, 77%-81%) for AISAPS, and 79% (95% CI, 77%-81%) for ISAN. The pooled score specificities were 73% (95% CI, 65%-80%) for A2DS2, 74% (95% CI, 69%-79%) for AISAPS, and 74% (95% CI, 69%-79%) for ISAN. We found significant heterogeneity for all the scoring systems based on the chi-square test results and an I2 statistic > 75%. We performed meta-regression to explore the source of heterogeneity and found that patient selection (pppp Conclusions: To summarize, we found that A2S2, AISAPS and ISAN have moderate predictive accuracy for SAP with A2S2 having a stable cutoff value.
The role of lithium production in massive AGB and super--AGB stars for the understanding of multiple populations in Globular Clusters

Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Lithium is made up in the envelopes of massive Asymptotic Giant Branch (AGB) stars through the process of Hot Bottom Burning. In Globular Clusters, this processing is one possible source of the hot-CNO burning whose nuclear products are then ejected into the intracluster medium and take part in the formation of a second stellar generation, explaining the peculiar distribution of chemical elements among the cluster stars. We discuss the lithium yields from AGB stars in the mass range 3-6.3 Msun, and from super-AGB stars of masses in the range 6.5-9 Msun for metallicity Z=0.001. The qualitative behaviour of these yields is discussed in terms of the physical structure of the different masses. Although many uncertainties affect the other yields of these stars (e.g. O, Na and Mg), even larger uncertainties affect the lithium yield, as it depends dramatically on the adopted description of mass loss. When we adopt our standard mass loss formulation, very large yields are obtained especially for the super-AGB stars, and we discuss their possible role on the lithium abundance of second generation stars in globular clusters.

On the Reliability of Multiple Systems Estimation for the Quantification of Modern Slavery

description: The quantification of modern slavery has received increased attention recently as organizations have come together to produce global estimates, where multiple systems estimation (MSE) is often used to this end. Echoing a long-standing controversy, disagreements have re-surfaced regarding the underlying MSE assumptions, the robustness of MSE methodology, and the accuracy of MSE estimates in this application. Our goal is to help address and move past these controversies. To do so, we review MSE, its assumptions, and commonly used models for modern slavery applications. We introduce all of the publicly available modern slavery datasets in the literature, providing a reproducible analysis and highlighting current issues. Specifically, we utilize an internal consistency approach that constructs subsets of data for which ground truth is available, allowing us to evaluate the accuracy of MSE estimators. Next, we propose a characterization of the large sample bias of estimators as a function of misspecified assumptions. Then, we propose an alternative to traditional (e.g., bootstrap-based) assessments of reliability, which allows us to visualize trajectories of MSE estimates to illustrate the robustness of estimates. Finally, our complementary analyses are used to provide guidance regarding the application and reliability of MSE methodology.

description: In this paper we study the interplay between the recently proposed F-theory GUTs and cosmology. Despite the fact that the parameter range for F-theory GUT models is very narrow, we find that F-theory GUTs beautifully satisfy most cosmological constraints without any further restrictions. The viability of the scenario hinges on the interplay between various components of the axion supermultiplet, which in F-theory GUTs is also responsible for breaking supersymmetry. In these models, the gravitino is the LSP and develops a mass by eating the axino mode. The radial component of the axion supermultiplet known as the saxion typically begins to oscillate in the early Universe, eventually coming to dominate the energy density. Its decay reheats the Universe to a temperature of ~ 1 GeV, igniting BBN and diluting all thermal relics such as the gravitino by a factor of ~ 10^(-4) - 10^(-5) such that gravitinos contribute a sizable component of the dark matter. In certain cases, non-thermally produced relics such as the axion, or gravitinos generated from the decay of the saxion can also contribute to the abundance of dark matter. Remarkably enough, this cosmological scenario turns out to be independent of the initial reheating temperature of the Universe. This is due to the fact that the initial oscillation temperature of the saxion coincides with the freeze out temperature for gravitinos in F-theory GUTs. We also find that saxion dilution is compatible with generating the desired baryon asymmetry from standard leptogenesis. Finally, the gravitino mass range in F-theory GUTs is 10-100 MeV, which interestingly coincides with the window of values required for the decay of the NLSP to solve the problem of Li(7) over-production.

description: We present the discovery of the widest (~6700 AU) very low mass field binary to date, found in a proper motion cross-match of the Sloan Digital Sky Survey and the Two Micron All Sky Survey. Our follow-up J-band imaging provides a 10-year baseline for measuring proper motions. Consequently, we are able to confirm the common proper motion of the pair to within 10 mas, implying a 99.5% probability of their physical association. Near infrared spectra of the components indicate spectral types of M6+/-1 and M7+/-1. The system resides at a spectroscopic distance of 105+/-13 pc and has an angular separation of 63.38+/-0.05 arcsec. We have used evolutionary models to infer component masses of 0.105^{+0.029}_{-0.017} M_sun and 0.091^{+0.010}_{-0.007} Msun. The large separation and low binding energy of this system can provide constraints for formation models of very low mass stars.
