description: It is well-established that increasing demands for fresh water are paving the way for desalination technologies. However, this correlates with an increase in brine production whose treatment and disposal can be complicated and expensive. This paper presents a thermodynamic model to bound the operation and development of a novel Humidification–Dehumidification-based system featuring Zero-Liquid Discharge and off-grid capabilities. The model employs conservation laws to find feasible state points to meet a baseline operation of 10 kg/h of product water separated from a hypersaline feed stream with 100 g/kg salt concentration. The system incurs in a 1039 kWh/m3 energy intensity that can be supplied completely by an electric source or in combination with heating steam. Follow-up sensitivity analysis highlights the robustness of the system in handling variations of 25% in product flowrate and 75% in feed salinity, practically without incurring any additional energy demands. The proposed system operating costs between 72 USD/m3 and 96 USD/m3 are comparable to those of existing brine disposal techniques. Furthermore, an operational map of existing desalination technologies suggests a niche characterized by high recovery rates and high feed salinities that are generally unfulfilled by conventional desalination methods. Overall, the proposed system shows potential for off-grid hypersaline brine treatment. This study sets the stage for future development of physics-based and data-driven predictive models as the proposed system iterates into a pilot plant deployment.

description: We continue the study of the covering complexity of constraint satisfaction problems (CSPs) initiated by Guruswami, Håstad and Sudan [SIAM J. Comp. 2002] and Dinur and Kol [CCC'13]. The covering number of a CSP instance $Φ$ is the smallest number of assignments to the variables of $Φ$, such that each constraint of $Φ$ is satisfied by at least one of the assignments. We show the following results: 1. Assuming a covering variant of the Unique Games Conjecture, introduced by Dinur and Kol, we show that for every non-odd predicate $P$ over any constant-size alphabet and every integer $K$, it is NP-hard to approximate the covering number within a factor of $K$. This yields a complete characterization of CSPs over constant-size alphabets that are hard to cover. 2. For a large class of predicates that are contained in the 2k-LIN predicate, we show that it is quasi-NP-hard to distinguish between instances with covering number at most $2$ and those with covering number at least $Ω(\log\log n)$. This generalizes and improves the 4-LIN covering hardness result of Dinur and Kol.

title: Anthelmintic resistance in equine parasites: an epidemiological approach to build a framework for sustainable parasite control
Creators: name: Lester, Hannah

Year: 2016

description: Faecal egg count (FEC) directed targeted anthelmintic treatment programmes and regular efficacy testing using the faecal egg count reduction test (FECRT) have been advocated to support evidence-based helminth control in horses. One major hurdle to their widespread application is that horse owners/managers and those that prescribe anthelmintics may have insufficient knowledge on which to base evidence-based protocols. The ultimate aim of this study was to create a framework for a decision support system (DSS) to support evidence-based helminth control in horses. To create the framework, the diagnostic performance of FEC and FECRT methodologies were evaluated. In addition, the efficacy of the three licensed anthelmintic classes was tested in several equine populations. The prevalence and distribution of helminths was determined in these populations, and an analysis undertaken to investigate factors associated with different levels of strongyle egg shedding in individuals. The consistency of egg shedding patterns in individuals over time was evaluated and the resource implications of following a FEC directed targeted treatment investigated. The FEC analysis findings support the rationale of FEC directed targeted anthelmintic treatments in horses to reduce treatment frequency in order to mitigate the impact of anthelmintic resistance. Moreover, the results show that such a strategy may be cost effective. The efficacy studies revealed that the macrocyclic lactone anthelmintics were highly effective in reducing strongyle egg output at two weeks after treatment, but further studies are required to analyse the strongyle egg reappearance period after treatment with these anthelmintics. In summary, this study validates the use of FEC directed treatment protocols in the field and the next step will be to use the derived information to design user-friendly online support tools.
title: Gamma-ray spectroscopic studies of 155Ho and 156Er

Publisher: name: University of Liverpool Repository

description: Excited states in 155Ho and 156Er extending to high spin have been populated as part of two experiments performed at the atlas facility of Argonne National Laboratory. In both experiments high-fold gamma-ray coincidence data were recorded in a high-statistics experiment with the Gammasphere spectrometer. In 156Er, weakly populated band structures have been established at low to medium spins, following the 114Cd(48Ca,6n) reaction at 215 MeV. Bands built on the second 0+ state and 2+ (gamma-vibrational) states have been established. A large staggering between the even- and odd-spin members of the gamma-vibrational band suggests a gamma-soft nature of this nucleus. An additional band is discussed as being based on a rotationally aligned �h9/2/f7/2 structure, coexisting with the systematically observed, more favourable (�i13/2)2 alignment seen in this mass region. At high spin, new transitions above the 42+ terminating state have been observed, establishing the presence of a further excited state, which is interpreted as the predicted terminating 46+ state built on a �particle-hole excitation (d5/2/g7/2 to d3/2) across the Z = 64 shell gap. New states in 155Ho have been observed following the 124Sn(37Cl,6n) reaction at 180 MeV. At low spin, a positive-parity �g7/2 rotational band, observed for the first time in this nucleus, has been established up to (33/2+). The �h11/2 band has been extended to higher spins, and the large signature splitting it exhibits interpreted as evidence of triaxiality at low spin. In addition, a positive-parity rotational structure has been extended to I� = 57/2− and discussed as being based on a �(i13/2h9/2) structure coupled to the h11/2 proton. B(M1)/B(E2) ratios of reduced transition probabilities have been calculated from observed branching ratios for all three bands and compared with theoretical calculations for specific particle configurations. Above spin � 59/2 the behaviour of the nucleus is discussed in the context of band termination. An energetically favoured state at I� = 79/2− has been established, which corresponds to valence-space band termination in 155Ho. Weak, high-energy core-breaking excitations feeding this state have been observed. New states with I� = (87/2+), (89/2+) are thought to be further predicted favoured terminating states at oblate shape, built on �(d5/2/g7/2 ! h11/2) particle-hole excitations across the Z = 64 shell gap. The newly observed high-spin states are compared to Cranked Nilsson Strutinsky calculations, and presented in the context of known band terminating states in the region.
title: The role of extracellular proteases in stromal-epithelial interactions in gastric cancer

description: Cancers of the upper gastrointestinal tract present at an advanced stage and carry a poor prognosis. Oesophageal and gastric tumours have a rich stroma composed of vascular cells, immune cells, and myofibroblasts, which promotes tumour growth, invasion and metastasis. In addition, mesenchymal stromal cells (MSCs) are recruited from the bone marrow to the tumour stroma; the mechanisms underpinning this have not yet been defined. Extracellular proteases play a role in cell migration, invasion, and cell signalling and are known to influence cancer growth in conflicting ways. Myofibroblasts present in normal tissue differ from those found in cancer. Cancer-associated myofibroblasts (CAMs) are known to modulate extracellular protease activity by secreting plasminogen activator inhibitor-1 (PAI-1), an inhibitor of the serine protease urokinase plasminogen activator, and matrix metalloproteinases (MMPs). This investigation studies the role of PAI-1 in gastric cancer and assesses the contribution of myofibroblast-derived MMPs to tumour growth. Finally, the role of chemerin in recruiting MSCs has been investigated. The expression of PAI-1 in myofibroblasts was found to be higher than in gastric cancer cells. Overexpression of PAI-1 in gastric cancer cells resulted in decreased cell adhesion and decreased tumour growth in an in vivo subcutaneous xenograft model of gastric tumour growth. The addition of gastric CAMs potentiated the growth of gastric cancer subcutaneous xenografts. This was not accounted for by differences in cell proliferation rate, apoptosis or final stromal content. Xenografts containing CAMs suppress the growth of a contralateral xenograft without CAMs, demonstrating that a long-range signal can be generated as a result of stromal-epithelial interactions. MMP and cathepsin activity was compared between xenografts containing myofibroblasts to those without. MMP activity is increased in xenografts injected with CAMs, compared to those injected with myofibroblasts taken from normal stomach or those with gastric cancer cells alone. In an organotypic co-culture system, MMP inhibition resulted in a decrease in gastric cancer cell invasion. The injection of fluorescently labelled MSCs injected resulted in homing of these cells to subcutaneous oesophageal tumours containing CAMs. Antagonism at the ChemR23 receptor inhibited this MSC homing to oesophageal xenografts containing CAMs. This work emphasises the importance of assessing the contribution of specific proteases and their inhibitors in gastric cancer. The stroma is an important contributor to extracellular protease activity and myofibroblasts contribute both proteases and their inhibitors to the tumour microenvironment, resulting in the modulation of tumour growth and cell adhesion. MSCs are recruited to oesophageal tumours via a novel signalling pathway.

description: Of the two main objectives we pursue in this paper, the first one consists in the studying operators of the form $(\partial_t-i\triangle_Γ)^α,\,\,α=1/2,-1/2,-1,\ldots,$ where $\triangle_Γ$ is the Laplace-Beltrami operator. These operators arise in the context of nonreflecting boundary conditions in the pseudo-differential approach for the general Schrödinger equation. The definition of such operators is discussed in various settings and a formulation in terms of fractional operators is provided. The second objective consists in deriving corner conditions for a rectangular domain in order to make such domains amenable to the pseudo-differential approach. Stability and uniqueness of the solution is investigated for each of these novel boundary conditions.

description: This article studies Albert the Great’s conception of reciprocal interiority in the exposition of John 14:10: “Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own; but the Father who dwells in me does his works” (Bible quotes from the New Revised Standard Version (NRSV)). Firstly, the article explores how Albert the Great understands reciprocal interiority as an element of the debate concerning the equality of the Father and of the Son, who, although identical in nature, are different according to the relation, like the one who begets and the one who is begotten. Secondly, it emphasizes the metaphysical solution that Albert borrows from Greek-Arabic neoplatonism, especially from the Liber de causis, so as to refute an objection based on Aristotle’s conception of place. This cultural transfer brings to light how Albert the Great’s Super Iohannem is an innovative melting pot in which Albert imports a new framework from profane sciences, with which to interpret the Gospel of John.

description: Tidal wetland ecosystems and their vegetation communities are broadly controlled by tidal range and inundation frequency. Sea-level rise combined with episodic flooding events are causing shifts in thresholds of vegetation species which reconstructs the plant zonation of the coastal landscape. More frequent inundation events in the upland forest are causing the forest to convert into tidal marshes, and what is left behind are swaths of dead-standing trees along the marsh–forest boundary. Upland forest dieback has been well documented in the mid-Atlantic; however, reliable methods to accurately identify this dieback over large scales are still being developed. Here, we use multitemporal Lidar and imagery from the National Agricultural Imagery Program to classify areas of forest loss in the coastal regions of Delaware. We found that 1197 ± 405 hectares of forest transitioned to non-forest over nine years, and these losses were likely driven by major coastal storms and severe drought during the study period. In addition, we report decreases in Lidar-derived canopy height in forest loss areas, suggesting forest structure changes associated with the conversion from forest to marsh. Our results highlight the potential value of integrating Lidar-derived metrics to determine specific forest characteristics that may help predict future marsh migration pathways.

They include deformations of the linearisations of the Prokushkin--Vasiliev higher spin theory around its critical points. They also provide unfolded formulations of linearized topologically massive higher spin fields including their critical versions. The gauge invariant degrees of freedom are captured by infinite towers of zero forms. We also introduce two inequivalent sets of gauge potentials given by trace constrained Fronsdal fields and trace unconstrained metric-like fields.

description: Streptococcus pyogenes, also known as the Group A Streptococcus (GAS), is a Gram-positive bacterial pathogen of major clinical significance. Despite remaining relatively susceptible to conventional antimicrobial therapeutics, GAS still causes millions of infections and hundreds of thousands of deaths each year worldwide. Thus, a need for prophylactic and therapeutic interventions for GAS is in great demand. In this study, we investigated the importance of the gene encoding the delta (δ) subunit of the GAS RNA polymerase, rpoE, for its impact on virulence during skin and soft-tissue infection. A defined 5448 mutant with an insertionally-inactivated rpoE gene was defective for survival in whole human blood and was attenuated for both disseminated lethality and lesion size upon mono-culture infection in mouse soft tissue. Furthermore, the mutant had reduced competitive fitness when co-infected with wild type (WT) 5448 in the mouse model. We were unable to attribute this attenuation to any observable growth defect, although colony size and the ability to grow at higher temperatures were both affected when grown with nutrient-rich THY media. RNA-seq of GAS grown in THY to late log phase found that mutation of rpoE significantly impacted (>2-fold) the expression of 429 total genes (205 upregulated, 224 downregulated), including multiple virulence and “housekeeping” genes. The arc operon encoding the arginine deiminase (ADI) pathway was the most upregulated in the rpoE mutant and this could be confirmed phenotypically. Taken together, these findings demonstrate that the delta (δ) subunit of RNA polymerase is vital in GAS gene expression and virulence.

description: Suppose that a set of mobile agents, each with a predefined maximum speed, want to patrol a fence together so as to minimize the longest time interval during which a point on the fence is left unvisited. In 2011, Czyzowicz, Gąsieniec, Kosowski and Kranakis studied this problem for the settings where the fence is an interval (a line segment) and a circle, and conjectured that the following simple strategies are always optimal: for Interval Patrolling, the simple strategy partitions the fence into subintervals, one for each agent, and lets each agent move back and forth in the assigned subinterval with its maximum speed; for Circle Patrolling, the simple strategy is to choose a number r, place the r fastest agents equidistantly around the circle, and move them at the speed of the rth agent. Surprisingly, these conjectures were then proved false: schedules were found (for some settings of maximum speeds) that slightly outperform the simple strategies. In this paper, we are interested in the ratio between the performances of optimal schedules and simple strategies. For the two problems, we construct schedules that are 4/3 times (for Interval Patrolling) and 21/20 times (for Circle Patrolling) as good, respectively, as the simple strategies. We also propose a new variant, in which we want to patrol a single point under the constraint that each agent can only visit the point some predefined time after its previous visit. We obtain some similar ratio bounds and NP-hardness results related to this problem.

title: HIV infection and stroke in Malawian adults
Creators: name: Benjamin, Laura
Publisher: name: University of Liverpool Repository
Year: 2014

description: There is an increased incidence of young people with stroke (age ≤45years) in Human immunodeficiency virus (HIV) endemic countries; this has been largely attributed to hypertension. However, hospital based surveys in countries like Malawi and South Africa have shown that the prevalence of hypertension in these young people is lower than expected, but HIV infection is substantially higher, implicating HIV as a risk factor. For many years a link between HIV and stroke has been postulated, but the relationship is uncertain. Whilst HIV may be a risk factor for stroke directly through mechanisms linked with HIV-associated vasculopathy, or indirectly through opportunistic infections, the drugs that treat HIV infection may also increase the risk of stroke because of their metabolic effects. Many studies, almost all retrospective, have failed to separate the direct effect of HIV infection from the indirect effects, including combined antiretroviral therapy, on cerebrovascular risk. HIV infection increases the risk of stroke mimics such as intracranial toxoplasma infection. The Recognition of Stroke in the Emergency Room (ROSIER) score is commonly used to screen for a stroke and triage patients for computer tomography (CT) of the brain. However, the accuracy of the ROSIER score and CT brain to reliably differentiate a stroke diagnosis from those with a stroke mimic in people with HIV infection is uncertain. I found that the ROSIER score and CT brain imaging had poor diagnostic accuracy in an HIV positive population. Therefore, in my thesis, every patient with an acute neurological symptom was fully assessed for a stroke as part of the screening process and confirmation was by magnetic resonance brain imaging. I subsequently investigated the risk factors and aetiology of stroke through a prospective case-control study in an HIV endemic country. Through this work, I showed that HIV infection is associated with cerebrovascular disease. Although hypertension was the leading risk factor in the population overall, HIV infection and its treatment was the second most important, and the most important in younger patients. Unexpectedly, I found that starting combined antiretroviral therapy in a subgroup of people living with HIV infection independently increased the risk of stroke. In this cohort, ischaemic stroke was the predominant stroke type and opportunistic infections only accounted for less than a third of these cases. The heterogeneity of HIV stroke with respect to risk factors for stroke, the degree of immunosuppression and HIV activity, and prior or current opportunistic infection has made it difficult to generalise epidemiological findings in some studies to populations at large. My study, to some extent unravels some of this ambiguity. I speculate that HIV related strokes evolves through the introduction of cART and then transitions into an aging population, accelerating atherosclerotic stroke and potentially contributing to an anticipated stroke epidemic in countries like Malawi.

description: Rainbow trout, Oncorhynchus mykiss, is an important cool, freshwater aquaculture species used as a model for biological research. However, its genome reference has not been annotated for epigenetic markers affecting various biological processes, including muscle growth/atrophy. Increased energetic demands during gonadogenesis/reproduction provoke muscle atrophy in rainbow trout. We described DNA methylation and its associated gene expression in atrophying muscle by comparing gravid, diploid females to sterile, triploid females. Methyl Mini-seq and RNA-Seq were simultaneously used to characterize genome-wide DNA methylation and its association with gene expression in rainbow trout muscle. Genome-wide enrichment in the number of CpGs, accompanied by depleted methylation levels, was noticed around the gene transcription start site (TSS). Hypermethylation of CpG sites within ±1 kb on both sides of TSS (promoter and gene body) was weakly/moderately associated with reduced gene expression. Conversely, hypermethylation of the CpG sites in downstream regions of the gene body +2 to +10 kb was weakly associated with increased gene expression. Unlike mammalian genomes, rainbow trout gene promotors are poor in CpG islands, at <1% compared to 60%. No signs of genome-wide, differentially methylated (DM) CpGs were observed due to the polyploidy effect; only 1206 CpGs (0.03%) were differentially methylated, and these were primarily associated with muscle atrophy. Twenty-eight genes exhibited differential gene expression consistent with methylation levels of 31 DM CpGs. These 31 DM CpGs represent potential epigenetic markers of muscle atrophy in rainbow trout. The DM CpG-harboring genes are involved in apoptosis, epigenetic regulation, autophagy, collagen metabolism, cell membrane functions, and Homeobox proteins. Our study also identified genes explaining higher water content and modulated glycolysis previously shown as characteristic biochemical signs of rainbow trout muscle atrophy associated with sexual maturation. This study characterized DNA methylation in the rainbow trout genome and its correlation with gene expression. This work also identified novel epigenetic markers associated with muscle atrophy in fish/lower vertebrates.
title: Elliptic curves over Galois number fields
Creators: name: Paterson, Ross Jarratt
Publisher: name: University of Glasgow
Year: 2023

description: This thesis is concerned with the statistical behaviour of elliptic curves over extension fields. That is, if K/Q is a finite extension, we study the arithmetic of E/K as E ranges in natural families of elliptic curves defined over Q. We study the statistical properties of the action of the group Aut(K) on E(K) and on the p-Selmer groups Selp(E/K) where p is a prime number. We construct special generalised Selmer groups, and show that these are related to certain representation-theoretic invariants of Selp(E/K). The sizes of these groups are related to the cokernels of the norm maps over the completions of K, which we go on to compute in several cases. In the statistical component of this thesis, we study quadratic twist families of elliptic curves and the family of ‘all elliptic curves’. For quadratic twist families we consider the behaviour over quadratic extensions. Using methods similar to those of Heath-Brown [HB93, HB94] and of Fouvry–Klüners [FK07], we determine the complete distribution of the 2-Selmer groups as Galois modules. This also allows us to determine representation-theoretic properties for the Mordell–Weil groups of 100% of twists. For the family of all elliptic curves over Q, we consider the behaviour with respect to a general finite Galois extension K/F. Writing G = Gal(K/F), our first main result is that the difference in dimension between Selp(E/K) G and Selp(E/F) has bounded average in this family. Using this we are able, with additional assumptions on K/F and p, to bound the average dimension of Selp(E/K) and so the average rank of the Mordell–Weil group E(K). Our methods also allow us to bound how often certain Z[G]-lattices occur as summands of E(K), with additional assumptions on F. We refine our results in the setting where K/Q is multiquadratic and p = 2, and prove strong upper and lower bounds for the average dimension of the 2-Selmer group.

description: The visual appearance of the fish fillet is a significant determinant of consumers’ purchase decisions. Depending on the rainbow trout diet, a uniform bright white or reddish/pink fillet color is desirable. Factors affecting fillet color are complex, ranging from the ability of live fish to accumulate carotenoids in the muscle to preharvest environmental conditions, early postmortem muscle metabolism, and storage conditions. Identifying genetic markers of fillet color is a desirable goal but a challenging task for the aquaculture industry. This study used weighted, single-step GWAS to explore the genetic basis of fillet color variation in rainbow trout. We identified several SNP windows explaining up to 3.5%, 2.5%, and 1.6% of the additive genetic variance for fillet redness, yellowness, and whiteness, respectively. SNPs are located within genes implicated in carotenoid metabolism (β,β-carotene 15,15′-dioxygenase, retinol dehydrogenase) and myoglobin homeostasis (ATP synthase subunit β, mitochondrial (ATP5F1B)). These genes are involved in processes that influence muscle pigmentation and postmortem flesh coloration. Other identified genes are involved in the maintenance of muscle structural integrity (kelch protein 41b (klh41b), collagen α-1(XXVIII) chain (COL28A1), and cathepsin K (CTSK)) and protection against lipid oxidation (peroxiredoxin, superoxide dismutase 2 (SOD2), sestrin-1, Ubiquitin carboxyl-terminal hydrolase-10 (USP10)). A-to-G single-nucleotide polymorphism in β,β-carotene 15,15′-dioxygenase, and USP10 result in isoleucine-to-valine and proline-to-leucine non-synonymous amino acid substitutions, respectively. Our observation confirms that fillet color is a complex trait regulated by many genes involved in carotenoid metabolism, myoglobin homeostasis, protection against lipid oxidation, and maintenance of muscle structural integrity. The significant SNPs identified in this study could be prioritized via genomic selection in breeding programs to improve fillet color in rainbow trout.

description: In this paper, we present a new method for computing bounded-degree factors of lacunary multivariate polynomials. In particular for polynomials over number fields, we give a new algorithm that takes as input a multivariate polynomial f in lacunary representation and a degree bound d and computes the irreducible factors of degree at most d of f in time polynomial in the lacunary size of f and in d. Our algorithm, which is valid for any field of zero characteristic, is based on a new gap theorem that enables reducing the problem to several instances of (a) the univariate case and (b) low-degree multivariate factorization. The reduction algorithms we propose are elementary in that they only manipulate the exponent vectors of the input polynomial. The proof of correctness and the complexity bounds rely on the Newton polytope of the polynomial, where the underlying valued field consists of Puiseux series in a single variable.

description: Multiple scattering and induced parton splitting lead to a medium modification of the QCD evolution for jet fragmentation functions and the final hadron spectra. Medium-induced parton splittings not only lead to energy loss of leading partons and suppression of leading hadron spectra, but also modify the flavor composition of a jet due to induced flavor conversion via gluon emission, quark pair production and annihilation. Through a numerical study of the medium-modified QCD evolution, leading $K^-$ strange meson spectra are found to be particularly sensitive to the induced flavor conversion in semi-inclusive deeply inelastic scatterings (SIDIS) off a large nucleus. The induced flavor conversion can lead to increased number of gluons and sea quarks in a jet and, as a consequence, enhance the leading $K^-$ spectra to counter the effect of parton energy loss in SIDIS with large momentum fractions $x_B$ where the struck quarks are mostly valence quarks of the nucleus.

description: Land use and management practice inputs to the Soil and Water Assessment Tool (SWAT) are critical for evaluating the impact of land use change and best management practices on soil erosion and water quality in watersheds. We developed an algorithm in this study to maximize the usage of land use and management records during the setup of SWAT for a small experimental watershed in New Brunswick, Canada. In the algorithm, hydrologic response units (HRUs) were delineated based on field boundaries and associated with long-term field records. The SWAT model was further calibrated and validated with respect to water flow and sediment and nutrient (nitrate and soluble phosphorus) loadings at the watershed outlet. As a comparison, a baseline version of SWAT was also set up using the conventional way of HRU delineation with limited information on land use and management practices. These two versions of SWAT were compared with respect to input and output resolution and prediction accuracy of monthly and annual water flow and sediment and nutrient loadings. Results show that the SWAT set up with the new method had much higher accuracies in generating annual areas of crops, fertilizer application, tillage operation, flow diversion terraces (FDT), and grassed waterways in the watershed. Compared with the SWAT set up with the conventional method, the SWAT set up with the new method improved the accuracy of predicting monthly sediment loading due to a better representation of FDT in the watershed, and it also successfully estimated the spatial impact of FDT on soil erosion across the watershed. However, there was no definite increase in simulation accuracy in monthly water flow and nutrient loadings with high spatial and temporal management inputs, though monthly nutrient loading simulations were sensitive to management configuration. The annual examination also showed comparable simulation accuracy on water flow and nutrient loadings between the two models. These results indicate that SWAT, although set up with limited land use and management information, is able to provide comparable simulations of water quantity and quality at the watershed outlet, as long as the estimated land use and management practice data can reasonably represent the average land use and management condition of the watershed over the target simulation period.

description: We propose, theoretically investigate, and numerically validate an algorithm for the Monte Carlo solution of least-squares polynomial approximation problems in a collocation frame- work. Our method is motivated by generalized Polynomial Chaos approximation in uncertainty quantification where a polynomial approximation is formed from a combination of orthogonal polynomials. A standard Monte Carlo approach would draw samples according to the density of orthogonality. Our proposed algorithm samples with respect to the equilibrium measure of the parametric domain, and subsequently solves a weighted least-squares problem, with weights given by evaluations of the Christoffel function. We present theoretical analysis to motivate the algorithm, and numerical results that show our method is superior to standard Monte Carlo methods in many situations of interest.

Soziale Arbeit mit nicht-binären Menschen: Eine Analyse von Coming-out Prozessen und Diskriminierungserfahrungen
Creators: name: Berger, Santiago
Publisher: name: Hochschule Luzern – Soziale Arbeit
Year: 2024

description: Die Bachelorarbeit «Soziale Arbeit mit nicht-binären Menschen» wurde von Santiago Berger verfasst und untersucht die Erfahrungen nicht-binärer Menschen in der Schweiz in Bezug auf ihre Coming-out Prozesse und Diskriminierungserfahrungen. Ausgangspunkt ist die gesellschaftliche Marginalisierung nicht-binärer Identitäten. Die zentrale Fragestellung lautet: Welche Erfahrungen haben nicht-binäre Menschen in ihren Coming-out Prozessen und Diskriminierungserfahrungen gemacht und wie können diese durch ihre Erfahrungen und Meinungen verbessert werden?

Methodisch basiert die Arbeit auf einer qualitativen Inhaltsanalyse, bei der fünf nicht-binäre Menschen interviewt wurden. Die Ergebnisse zeigen sowohl positive Erfahrungen wie die Unterstützung durch soziale Netzwerke als auch negative Erfahrungen wie Diskriminierungen und fehlende Anerkennung.

Die Arbeit gibt praxisorientierte Handlungsempfehlungen für die Soziale Arbeit, darunter die Förderung der Aufklärung über Geschlechtsidentitäten, die Umsetzung von Antidiskriminierungsgesetzen und die Unterstützung durch soziale Netzwerke. Die Forschung unterstreicht die Bedeutung umfassender Aufklärung und rechtlicher Anerkennung für die Verbesserung der Lebenssituation nicht-binärer Menschen. Diese Erkenntnisse sind wesentlich für die Entwicklung effektiver Interventionsstrategien für die Soziale Arbeit.

description: Objective: Afghanistan is one of the countries with the highest prevalence of spousal violence (56%) and a low prevalence of contraceptive use (23%), yet there is no study assessing how spousal violence is related to contraceptive use, and what methods are most used by women. Therefore, this study examined the association between the number of types of spousal violence and contraceptive use. Method: Using data from 18,985 Afghan married women, aged 15 to 49, who responded to the 2015 Afghanistan Demographic and Health Survey, the current contraceptive method was grouped into five categories: male-involved methods, pills, injectables, long-acting reversible contraception, female sterilization, and Lactation Amenorrhea Method. The number of types of spousal violence in the past 12 months was categorized as none, one type, or two or more types, based on women’s experiences with verbal, physical, and sexual violence. For analysis, binary and multinomial logistic regression were used. Results: After adjusting for the covariates, the experience of any spousal violence was associated with contraception use (adjusted odds ratio (aOR) = 1.93, 95% CI: 1.64–2.27, p = 0.0001). Among those using contraception, experiencing two or three types of spousal violence was associated with using pills (adjusted risk ratio (aRRR) = 2.12, 95% CI: 1.63–2.77, p = 0.0001), injections (aRRR = 1.75, 95% CI: 1.26–2.41, p = 0.001), and LAM (aRRR = 3.27, 95% CI: 2.05–5.20, p = 0.0001), compared to male-involved methods. Conclusions: The findings of this study may inform policymakers and program implementers in designing interventions to address the pervasive problem of violence against women, and make pills and injectables more accessible to Afghan women, since these methods are under women’s control and more often used in Afghanistan.

description: Adverse drug reactions (ADRs) in children are common but their predictors are not fully characterised. It is known that both increasing age and number of concomitant medicines increase ADR risk in children, and there is also some evidence that off-label and unlicensed medicine use may contribute. The purpose of the thesis was to characterise ADRs in children, focusing on known risk factors, which have not been adequately evaluated in the literature. The contribution of off-label and unlicensed prescribing to ADR risk in children was assessed in two large prospective studies. In the first study, which evaluated ADR-related hospital admissions, off-label or unlicensed medicines were more likely to be implicated in an ADR than authorised medicines (relative risk 1.67, 95% CI 1.38, 2.02, p

description: Plants have evolved to protect leaf mesophyll tissue from damage caused by UV-B radiation by producing an array of UV-absorbing secondary metabolites. Flavonoids (phenolic glycosides) and sinapate esters (hydroxycinnamates) have been implicated as UV-B protective compounds because of the accumulation in the leaf epidermis and the strong absorption in the wavelengths corresponding to UV. Environmental adaptations by plants also generate a suite of responses for protection against damage caused by UV-B radiation, with plants from high elevations or low latitudes generally displaying greater adaptation or tolerance to UV-B radiation. In an effort to explore the relationships between plant lignin levels and composition, the origin of growth elevation, and the hierarchical synthesis of UV-screening compounds, a collection of natural variants as well as transgenic Populus spp. were examined for sensitivity or acclimation to UV-B radiation under greenhouse and laboratory conditions. Noninvasive, ecophysiological measurements using epidermal transmittance and chlorophyll fluorescence as well as metabolite measurements using UPLC-MS generally revealed that the synthesis of anthocyanins, flavonoids, and lignin precursors are increased in Populus upon moderate to high UV-B treatment. However, poplar plants with genetic modifications that affect lignin biosynthesis, or natural variants with altered lignin levels and compositions, displayed complex changes in phenylpropanoid metabolites. A balance between elevated metabolic precursors to protective phenylpropanoids and increased biosynthesis of these anthocyanins, flavonoids, and lignin is proposed to play a role in the acclimation of Populus to UV-B radiation and may provide a useful tool in engineering plants as improved bioenergy feedstocks.
