Subjects: Sheep
Goat

description: The “Pastores de Galicia” brand was created by the Association of Sheep and Goats Breeders of Galicia in 2015. Its objective is to distinguish in the market the lamb and goat meat produced in Galicia and associated with the use of natural resources by grazing mothers and feeding lambs and kids based on breast milk directly from the udder and cereals.

The “Pastores de Galicia” brand serves as a guarantee of origin, production system, food safety, animal welfare and quality. The current challenge is to publicize brand and product as well as its position in market in order to allow consumers to have access to a high-quality guaranteed meat. Meat from this extensive production system has excellent nutritional & organoleptic qualities. Animals are linked to a sustainable breeding system at environmental level. Extensive livestock grazing systems based on fresh pastures are an active part of the environment in which it is located. These systems provide protection against forest fires while fertilize the soils in a natural form, among other benefits.

The Association of Sheep and Goats Breeders of Galicia is currently facing a divide between the food consumer and the origin of food. However, it has been detected a new tendency of consumers worrying about the sustainability and the quality of the food they consume. “Pastores de Galicia” allows to connect the security, quality and sustainability of the territory with the guarantee of a product of exceptional qualities for the final consumer.

description: Objective: In the absence of head-to-head trials, this study indirectly compared progression free survival (PFS) and overall survival (OS) between ceritinib and crizotinib among patients with previously untreated advanced anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). Methods: A matching-adjusted indirect comparison method was implemented to adjust for cross-trial differences in patient characteristics between ASCEND-4 and PROFILE 1014 trials. Patient-level data from ASCEND-4 and published summary data from PROFILE 1014 were used. Patients in ASCEND-4 were reweighted to match average baseline characteristics (i.e. age, sex, race, tumor histology, ECOG score, smoking status, extent of disease, and presence of brain metastases) reported for PROFILE 1014 patients using propensity score weighting. PFS and OS were then compared between balanced populations. Results: ASCEND-4 included more current smokers (8.0% vs 4.4%) and fewer patients under the age of 65 years (78.5% vs 84.0%) compared to PROFILE 1014. After matching, these and all other patient characteristics were balanced between the two trial populations. Compared to crizotinib, ceritinib was associated with a significantly longer PFS (hazard ratio [95% confidence interval] (HR [CI]) = 0.64 [0.47–0.87]; median PFS: 25.2 vs 10.8 months, log-rank p-value = 0.003). OS did not differ significantly, with a HR of 0.82 [0.54–1.27] for ceritinib compared to crizotinib. Conclusions: In the adjusted indirect comparison with external controls, the second generation ALK inhibitor, ceritinib, was associated with a significantly prolonged PFS compared to crizotinib as first-line treatment for ALK-positive NSCLC.

description: Light quark masses are computed for Kogut-Susskind fermions by evaluating non-perturbatively the renormalization factor for bilinear quark operators. Calculations are carried out in the quenched approximation at β=6.0, 6.2, and 6.4. For the average up and down quark mass we find $m_{\bar MS}(2 GeV)= 4.15(27) MeV$ in the continuum limit, which is significantly larger than $3.51(20) MeV$ ($q^*=1/a$) or $3.40(21) MeV$ ($q^*=π/a$) obtained with the one-loop perturbative renormalization factor.

description: We consider the problem of online path planning for joint detection and tracking of multiple unknown radio-tagged objects. This is a necessary task for gathering spatio-temporal information using UAVs with on-board sensors in a range of monitoring applications. In this paper, we propose an online path planning algorithm with joint detection and tracking because signal measurements from these objects are inherently noisy. We derive a partially observable Markov decision process with a random finite set track-before-detect (TBD) multi-object filter, which also maintains a safe distance between the UAV and the objects of interest using a void probability constraint. We show that, in practice, the multi-object likelihood function of raw signals received by the UAV in the time-frequency domain is separable and results in a numerically efficient multi-object TBD filter. We derive a TBD filter with a jump Markov system to accommodate maneuvering objects capable of switching between different dynamic modes. Our evaluations demonstrate the capability of the proposed approach to handle multiple radio-tagged objects subject to birth, death, and motion modes. Moreover, this online planning method with the TBD-based filter outperforms its detection-based counterparts in detection and tracking, especially in low signal-to-noise ratio environments.

Towards transformative urban sustainability experimentations : possible pathways to affordable housing in Canada
Creators: name: Forouzandeh, Peyvand
Publisher: name: University of British Columbia
Year: 2025

description: Fostering sustainability transitions is an urgent global challenge, and urban Sustainability Experimentations (SEs) have emerged as a critical approach to addressing pressing urban issues through collaboration across various sectors for accelerating urban transitions. Despite their increasing significance, academic literature on SEs in Canada remains in its early stages. In Canada, various SE models and theories have evolved organically, manifested in models such as Social Innovation Labs, Urban Living Labs, Public Sector Innovation Labs, and Demonstrations. This research addresses How Canadian urban sustainability experimentations (SEs) can become more transformative? To explore this, this research employs a multi-step qualitative case study approach, beginning with a survey of 16 organizations leading SEs across Canada. This step identifies factors contributing to SEs’ diversity, uncovering common challenges and critical elements examined in their processes and broader urban interactions. The second step focuses on two ongoing SEs related to sustainable, affordable housing in Vancouver and Calgary. Data collection included participant interviews, projects and policy document reviews, and observation of decision-making processes. Through in-depth analysis, this research explores the urban dimensions of SEs, their context-specific characteristics within the Canadian setting, and the factors and key dimensions that contribute to their transformative qualities. The evidence presented in this dissertation highlights that Canadian SEs face significant challenges, including a tendency toward short-term planning, fragmented efforts, uncertainty about long-term impacts, and various contextual and governance factors that hinder their potential to contribute to broader urban transitions. This research provides in-depth discussions, analyses, and conceptual frameworks to identify the key dynamics and dimensions essential for guiding SEs toward broader transformative effects, extending beyond their immediate scope. These factors include but are not limited to shared goal setting, incentivizing risk-taking, connections with broader urban agendas, policies, and other initiatives, cross-disciplinary knowledge co-creation, targeted knowledge dissemination, the confluence of funding programs, research leadership, integrated evaluation in decision-making processes, and attention to power dynamics. The analysis concludes that, despite challenges in navigating uncertainties and evaluating SEs during their processes and limited evidence on their long-term transformative potential, several critical elements can potentially guide practitioners, policymakers, and researchers in steering SEs toward more transformative effects.

description: We present two matched sets of five simulations each, covering five presently favored simple modifications to the standard cold dark matter (CDM) scenario. One simulation suite, with a linear box size of 75 Mpc/h, is designed for high resolution and good statistics on the group/poor cluster scale, and the other, with a box size of 300 Mpc/h, is designed for good rich cluster statistics. All runs had 57 million cold particles, and models with massive neutrinos had an additional 113 million hot particles. We consider separately models with massive neutrinos, tilt, curvature, and a nonzero cosmological constant in addition to the standard CDM model. We find that our tilted Omega+Omega_Lambda=1 (TLCDM) model produces too much small-scale power by a factor of ~3, and our open Lambda=0 (OCDM) model also exceeds observed small-scale power by a factor of 2. In addition, we take advantage of the large dynamic range in detectable halo masses our simulations allow to check the shape of the Press-Schechter approximation. We find good fits at cluster masses for delta_c=1.27--1.35 for a Gaussian filter and delta_c=1.57--1.73 for a tophat filter. However, Press-Schechter overpredicts the number density of halos compared to the simulations in the high resolution suite by a weakly cosmology-dependent factor of 1.5--2 at galaxy and group masses, which cannot be fixed by adjusting delta_c within reasonable bounds. An appendix generalizes the spherical collapse model to any isotropic cosmology.

description: Green and Lindqvist proved that for any 2-colouring of $\mathbb{N}$, there are in\-fi\-ni\-tely many monochromatic solutions to $x+y=z^2$. In fact, they showed the existence of a monochromatic solution in every interval $[N,cN^8]$ with large enough $N$. In this short note we give a different proof for their theorem and prove that a monochromatic solution exists in every interval $[N,10^4N^4]$ with large enough $N$. A 2-colouring of $[N,(1/27)N^4]$ avoiding monochromatic solutions to $x+y=z^2$ is also presented, which shows that in $10^4N^4$ only the constant factor can be reduced.

description: For a compact Poisson-Lie group $K$, the homogeneous space $K/T$ carries a family of symplectic forms $ω_ξ^s$, where $ξ\in \mathfrak{t}^*_+$ is in the positive Weyl chamber and $s \in \mathbb{R}$. The symplectic form $ω_ξ^0$ is identified with the natural $K$-invariant symplectic form on the $K$ coadjoint orbit corresponding to $ξ$. The cohomology class of $ω_ξ^s$ is independent of $s$ for a fixed value of $ξ$. In this paper, we show that as $s\to -\infty$, the symplectic volume of $ω_ξ^s$ concentrates in arbitrarily small neighbourhoods of the smallest Schubert cell in $K/T \cong G/B$. This strengthens earlier results [9,10] and is a step towards a conjectured construction of global action-angle coordinates on $Lie(K)^*$ [4, Conjecture 1.1].

description: We formulate the equivalence theorem as a theoretical criterion for sensitively probing the electroweak symmetry breaking mechanism, and develop a precise power counting method for the chiral Lagrangian formulated electroweak theories. Armed with these, we perform a systematic analysis on the sensitivities of the scattering processes $W^\pm W^\pm \rightarrow W^\pm W^\pm$ and $q\bar{q}'\rightarrow W^\pm Z$ for testing all possible effective bosonic operators in the chiral Lagrangian formulated electroweak theories at the CERN Large Hadron Collider (LHC). The analysis shows that these two kinds of processes are "complementary" in probing the electroweak symmetry breaking sector.

subject: Primary health care

description: Background: Providing alcohol screening and brief advice (SBA) in primary health care (PHC) can be an effective measure to reduce alcohol consumption. To aid successful implementation in an upper middle-income country context, this study investigates the perceived appropriateness
of the programme and the perceived barriers to its implementation in PHC settings in three Latin American countries: Colombia, Mexico and Peru, as part of larger implementation study (SCALA).
Methods: An online survey based on the Tailored Implementation for Chronic Diseases (TICD) implementation framework was disseminated in the three countries to key stakeholders with experience in the topic and/or setting (both health professionals and other roles, for
example regional health administrators and national experts). In total, 55 respondents participated (66% response rate). For responses to both appropriateness and barriers questions, frequencies were computed, and country comparisons were made using Chi square and Kruskal–Wallis non-parametric tests. Results: Alcohol SBA was seen as an appropriate programme to reduce heavy alcohol use in PHC and a range of providers were considered suitable for its delivery, such as general practitioners, nurses, psychologists and social workers. Contextual factors such as patients’ normalised perception of their heavy drinking, lack of on-going support for providers, difficulty of accessing referral services and lenient alcohol control laws were the highest rated barriers. Country differences were found for two barriers: Peruvian respondents rated SBA guidelines as
less clear than Mexican (Mann–Whitney U = -18.10, P = 0.001), and more strongly indicated lack of available screening instruments than Colombian (Mann–Whitney U = -12.82, P = 0.035) and Mexican respondents (Mann–Whitney U = -13.56, P = 0.018).
Conclusions: The study shows the need to address contextual factors for successful implementation of SBA
in practice. General congruence between the countries suggests that similar approaches can be used to encourage widespread implementation of SBA in all three studied countries, with minor tailoring based on the few country-specific barriers.

The effect of finite chemical potential is also considered. In both cases, the systems are decoupled into an infinite number of 1+1 fermions by Fourier transformation in the $β$-variable. The total effective actions demonstrate non-extensiveness in the $β$ dimension.

description: The spectrum of open strings on various non-BPS D-brane configurations in type II string theory on a K3 orbifold is analysed. At a generic point in the corresponding moduli space the spectrum of open strings does not have any degeneracy between bosonic and fermionic states. However, there exist special values for these moduli for which many non-BPS D-brane configurations have an exactly bose-fermi degenerate open string spectrum at all mass levels. In this case the closed string exchange interaction between a pair of such D-brane configurations vanishes at all distances.

description: We present a method, based on the correlation function of excursion sets above a given threshold, to test the Gaussianity of the CMB temperature fluctuations in the sky. In particular, this method can be applied to discriminate between standard inflationary scenarios and those producing non-Gaussianity such as topological defects. We have obtained the normalized correlation of excursion sets, including different levels of noise, for 2-point probability density functions constructed from the Gaussian, χ_n^2 and Laplace 1-point probability density functions in two different ways. Considering subdegree angular scales, we find that this method can distinguish between different distributions even if the corresponding marginal probability density functions and/or the radiation power spectra are the same.

description: We investigate opinion dynamics and information spreading on networks under the influence of content filtering technologies. The filtering mechanism, present in many online social platforms, reduces individuals' exposure to disagreeing opinions, producing algorithmic bias. We derive evolution equations for global opinion variables in the presence of algorithmic bias, network community structure, noise (independent behavior of individuals), and pairwise or group interactions. We consider the case where the social platform shows a predilection for one opinion over its opposite, unbalancing the dynamics in favor of that opinion. We show that if the imbalance is strong enough, it may determine the final global opinion and the dynamical behavior of the population. We find a complex phase diagram including phases of coexistence, consensus, and polarization of opinions as possible final states of the model, with phase transitions of different order between them. The fixed point structure of the equations determines the dynamics to a large extent. We focus on the time needed for convergence and conclude that this quantity varies within a wide range, showing occasionally signatures of critical slowing down and meta-stability.

description: This investigation is concerned with cosmological scenarios based on particle physics theories that give rise to superconducting cosmic strings (whose subsequent evolution may produce stable loop configurations known as vortons). Cases in which electromagnetic coupling of the string current is absent or unimportant have been dealt with in previous work. The purpose of the present work is to provide quantitative estimates for cases in which electromagnetic interaction with the surrounding plasma significantly affects the string dynamics. In particular it will be shown that the current can become sufficiently strong for the initial period of friction dominated string motion to be substantially prolonged, which would entail a reinforcement of the short length scale end of the spectrum of the string distribution, with potentially observable cosmological implications if the friction dominated scenario lasts until the time of plasma recombination.

Use of long-read sequencing for variant detection and diagnosis of neurodevelopmental disorders
Creators: name: Dada, Sarah
Publisher: name: University of British Columbia
Year: 2025

description: Neurodevelopmental disorders are a broad set of disorders impacting cognition, motor skills, adaptive behaviours, and communication that impact about 15% of children and adolescents globally. They include autism spectrum disorder as well as imprinting disorders such as Temple syndrome, Prader-Willi syndrome, and Angelman syndrome. Neurodevelopmental disorders encompass overlapping phenotypes and co-morbidities, which thereby make them difficult to diagnose, however the diagnosis of these disorders in a timely manner is critical for long-term quality of life. The diagnosis of autism spectrum disorder is behaviourally based, despite having up to 80% genetic underpinning involving molecular heterogeneity. The diagnosis of imprinting disorders currently relies on the interpretation of several molecular techniques to elucidate the many components which may contribute to disorder, such as methylation aberrations or copy number changes. Using many techniques increases the time to diagnosis and treatment, and incurs cost through repeated diagnostic testing and healthcare specialist time. The use of broader all-in-one techniques would alleviate the burden on the healthcare system and improve quality of care through a rapid and precise diagnosis. In this thesis, I investigate the use of long-read whole genome sequencing for precision diagnosis and subtyping of several neurodevelopmental disorders. Long reads overcome known limitations of next generation short-read whole-genome sequencing within large or complex structural variants and GC-rich repetitive regions. Long reads detect both DNA sequence and methylation, and phase haplotypes. I use long-read sequencing to accurately delineate complex structural variants and determine pertinent DNA methylation patterns, which inform clinical diagnosis of individuals with autism spectrum disorder. I use long-read sequencing to detect imprinting disorders Prader-Willi syndrome, Angelman syndrome, and Temple syndrome, and determine their subtypes by determining parent-of-origin specific defects through haplotype phasing, through the use of known imprinting regions to determine heterodisomy and isodisomy, through the detection of copy number loss, and through the detection of small insertions and deletions. In totality, this thesis demonstrates that long-read sequencing presents as a feasible all-in-one option to detect complex and multi-faceted causes of disorder that are both genetic and DNA methylation based, and can provide rapid and accurate diagnosis and treatment of neurodevelopmental disorders.

description: A series of tertiary sulphonamide derivatives were synthesised and evaluated for their antiproliferative activity against liver cancer cell lines (SNU-475, HepG-2, and Bel-7402). Among these tertiary sulphonamides, compound 17a displayed the best anti-liver cancer activity against Bel-7402 cells with an IC50 value of 0.32 μM. Compound 17a could effectively inhibit tubulin polymerisation with an IC50 value of 1.27 μM. Meanwhile, it selectively suppressed LSD1 with an IC50 value of 63 nM. It also concentration-dependently inhibited migration against Bel-7402 cells. Importantly, tertiary sulphonamide 17a exhibited the potent antitumor activity in vivo. All these findings revealed that compound 17a might be a tertiary sulphonamide-based dual inhibitor of tubulin polymerisation and LSD1 to treat liver cancer.

description: Over the last decade, researchers have extensively explored the vulnerabilities of Android malware detectors to adversarial examples through the development of evasion attacks; however, the practicality of these attacks in real-world scenarios remains arguable. The majority of studies have assumed attackers know the details of the target classifiers used for malware detection, while in reality, malicious actors have limited access to the target classifiers. This paper introduces EvadeDroid, a problem-space adversarial attack designed to effectively evade black-box Android malware detectors in real-world scenarios. EvadeDroid constructs a collection of problem-space transformations derived from benign donors that share opcode-level similarity with malware apps by leveraging an n-gram-based approach. These transformations are then used to morph malware instances into benign ones via an iterative and incremental manipulation strategy. The proposed manipulation technique is a query-efficient optimization algorithm that can find and inject optimal sequences of transformations into malware apps. Our empirical evaluations, carried out on 1K malware apps, demonstrate the effectiveness of our approach in generating real-world adversarial examples in both soft- and hard-label settings. Our findings reveal that EvadeDroid can effectively deceive diverse malware detectors that utilize different features with various feature types. Specifically, EvadeDroid achieves evasion rates of 80%-95% against DREBIN, Sec-SVM, ADE-MA, MaMaDroid, and Opcode-SVM with only 1-9 queries. Furthermore, we show that the proposed problem-space adversarial attack is able to preserve its stealthiness against five popular commercial antiviruses with an average of 79% evasion rate, thus demonstrating its feasibility in the real world.

description: Objective: In the absence of head-to-head trials, this study indirectly compared progression free survival (PFS) and overall survival (OS) between ceritinib and crizotinib among patients with previously untreated advanced anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). Methods: A matching-adjusted indirect comparison method was implemented to adjust for cross-trial differences in patient characteristics between ASCEND-4 and PROFILE 1014 trials. Patient-level data from ASCEND-4 and published summary data from PROFILE 1014 were used. Patients in ASCEND-4 were reweighted to match average baseline characteristics (i.e., age, sex, race, tumor histology, ECOG score, smoking status, extent of disease, and presence of brain metastases) reported for PROFILE 1014 patients using propensity score weighting. PFS and OS were then compared between balanced populations. Results: ASCEND-4 included more current smokers (8.0% vs. 4.4%) and fewer patients under the age of 65 years (78.5% vs. 84.0%) compared to PROFILE 1014. After matching, these and all other patient characteristics were balanced between the two trial populations. Compared to crizotinib, ceritinib was associated with a significantly longer PFS (hazard ratio [95% confidence interval] (HR: [CI]) = 0.64 [0.47, 0.87]; median PFS: 25.2 vs. 10.8 months, log-rank p-value =0.003). OS did not differ significantly, with a HR of 0.82 [0.54, 1.27] for ceritinib compared to crizotinib. Conclusions: In the adjusted indirect comparison with external controls, the second generation ALK inhibitor, ceritinib, was associated with a significantly prolonged PFS compared to crizotinib as first-line treatment for ALK-positive NSCLC.
Gluon Spin in the Nucleon

description: We study the operator description of the gluon spin contribution ($Γ$) to the nucleon's spin as it is measured in deep inelastic processes. $Γ$ can be related to the forward matrix element of a local gluon operator in $A^+=0$ gauge. In quark models the nucleon contains ambient color electric and magnetic fields. The latter are thought to be responsible for spin splittings among the light baryons. We show that these fields give rise to a significant {\it negative\/} contribution to $Γ$ at the quark model renormalization scale, $μ_0^2$. The non-Abelian character of QCD is responsible for the sign of $Γ$. In a generic non-relativistic quark model $Γ_{NQM}=-{8\over 9}{α_{NQM}\over m_q}\langle{1\over r}\rangle$, in the bag model $Γ_{bag}=-.1α_{bag}$. These correspond to $Γ_{NQM}\approx -0.7$ and $Γ_{bag}\approx -0.4$ at $α_{QCD}\approx 1.0$.

description: Low-dose CT image reconstruction has been a popular research topic in recent years. A typical reconstruction method based on post-log measurements is called penalized weighted-least squares (PWLS). Due to the underlying limitations of the post-log statistical model, the PWLS reconstruction quality is often degraded in low-dose scans. This paper investigates a shifted-Poisson (SP) model based likelihood function that uses the pre-log raw measurements that better represents the measurement statistics, together with a data-driven regularizer exploiting a Union of Learned TRAnsforms (SPULTRA). Both the SP induced data-fidelity term and the regularizer in the proposed framework are nonconvex. The proposed SPULTRA algorithm uses quadratic surrogate functions for the SP induced data-fidelity term. Each iteration involves a quadratic subproblem for updating the image, and a sparse coding and clustering subproblem that has a closed-form solution. The SPULTRA algorithm has a similar computational cost per iteration as its recent counterpart PWLS-ULTRA that uses post-log measurements, and it provides better image reconstruction quality than PWLS-ULTRA, especially in low-dose scans.

description: Urban areas serve as melting pots of people with diverse socioeconomic backgrounds, who may not only be segregated but have characteristic mobility patterns in the city. While mobility is driven by individual needs and preferences, the specific choice of venues to visit is usually constrained by the socioeconomic status of people. The complex interplay between people and places they visit, given their personal attributes and homophily leaning, is a key mechanism behind the emergence of socioeconomic stratification patterns ultimately leading to urban segregation at large. Here we investigate mixing patterns of mobility in the twenty largest cities of the United States by coupling individual check-in data from the social location platform Foursquare with census information from the American Community Survey. We find strong signs of stratification indicating that people mostly visit places in their own socioeconomic class, occasionally visiting locations from higher classes. The intensity of this `upwards bias' increases with socioeconomic status and correlates with standard measures of racial residential segregation. Our results indicate an even stronger socioeconomic segregation in individual mobility than one would expect from system-level distributions, shedding further light on uneven mobility mixing patterns in cities.

description: In this paper, we propose a novel sequential data-driven method for dealing with equilibrium based chemical simulations, which can be seen as a specific machine learning approach called active learning. The underlying idea of our approach is to consider the function to estimate as a sample of a Gaussian process which allows us to compute the global uncertainty on the function estimation. Thanks to this estimation and with almost no parameter to tune, the proposed method sequentially chooses the most relevant input data at which the function to estimate has to be evaluated to build a surrogate model. Hence, the number of evaluations of the function to estimate is dramatically limited. Our active learning method is validated through numerical experiments and applied to a complex chemical system commonly used in geoscience.

description: We establish the existence of a scaling limit $\mathcal{E}_p$ of discrete $p$-energies on the graphs approximating generalized Sierpiński carpets for $p > \dim_{\text{ARC}}(\textsf{SC})$, where $\dim_{\text{ARC}}(\textsf{SC})$ is the Ahlfors regular conformal dimension of the underlying generalized Sierpiński carpet. Furthermore, the function space $\mathcal{F}_{p}$ defined as the collection of functions with finite $p$-energies is shown to be a reflexive and separable Banach space that is dense in the set of continuous functions with respect to the supremum norm. In particular, $(\mathcal{E}_2, \mathcal{F}_2)$ recovers the canonical regular Dirichlet form constructed by Barlow and Bass or Kusuoka and Zhou. We also provide $\mathcal{E}_{p}$-energy measures associated with the constructed $p$-energy and investigate its basic properties like self-similarity and chain rule.
