description: Гипертрофическая кардиомиопатия (ГКМП) - это первичное поражение миокарда с гипертрофией левого желудочка, реже правого желудочка, которое вызвано мутациями в генах сократительных белков миокарда. ГКМП является самой частой из генетически обусловленных кардиомиопатий и остается актуальной проблемой современной кардиологии, что объясняется возможным прогредиентным течением заболевания и развитием смертельных осложнений - нарушения ритма сердца, внезапная сердечная смерть, хроническая сердечная недостаточность. Особенностью ГКМП является ее генетическая и фенотипическая гетерогенность. Известны более 20 генов, кодирующих три функциональных класса белков, мутации в которых могут привести к заболеванию. Фенотипические проявления заболевания могут существенно различаться даже в рамках одной семьи. В статье представлен редкий случай разных портретов семейной ГКМП двух родных братьев. Описаны: течение заболевания, методы и результаты диагностики, стратегия лечения в зависимости от фенотипа заболевания, проявляющегося у одного с образованием обструкции выносящего отдела ЛЖ, у другого - без такового.

description: Two models of long-term land use, the ecological and contextual models, have been used to explain continuity and change in the patterned use of sites by hunter-gatherers. Recent excavations at the deeply stratified Stampede site (DjOn-26) have revealed remarkable continuity in the use of space throughout the past 8,000 years; however, post-depositional disturbances have resulted in the slumping and displacement of individual paleosols, posing a challenge for artefact associations and inter-paleosol comparison. This thesis will examine the spatial distribution of cultural materials and hearth assemblages from the Stampede site, located in the Cypress Hills, Alberta. Three-dimensional spatial analysis is combined with GIS to correct slumped deposits and refine archaeologically defined levels. Two-dimensional spatial analysis is then applied to investigate the patterning of materials and non-portable features in successive occupations. The results will provide an opportunity to critically evaluate long-term land use models through comparison of the nature and organization of activities during specific occupation phases at the Stampede site.

description: Цель исследования. Изучить взаимосвязи фетуина А крови с клиническими параметрами и влияние его снижения на вероятность обнаружения сердечно-сосудистой кальцификации у больных с ХБП С5Д. Материал и методы. Исследование одномоментное, когортное на 84 больных с ХБП 5Д стадии, получавших терапию гемодиализом, из них 40 пациентов женского пола и 44 - мужского пола. Средний возраст больных составил 55,6±14,9 лет. Обследование включало, помимо рутинных исследований, выполнение эхокардиоскопии с оценкой кальцификации клапанов сердца, рентгенографии живота в боковой проекции с оценкой кальцификации аорты, анализ показателей, характеризующих фосфорно-кальциевых обмен. Результаты. Подтверждено влияние снижения уровня фетуина А на риск вывления кальцификации стенки аорты и клапанов сердца. Низкий уровень фетуина А не только повышает вероятность самой кальцификации, но и ее выраженности. Было показано, что фетуин А способен осуществлять это в совокупности с a-klotho. Оба фактора обладают протективными свойствами в отношении кальцификации, и их содружественное снижение также способствует ее развитию. Заключение. Таким образом, снижение уровня фетуина А в крови у больных с ХБП С5Д способствует повышению риска формирования кальцификации клапанов сердца и стенки аорты как самостоятельно, так и в совокупности со снижением уровня a-klotho. Низкие значения фетуина А повышают выраженность сердечно-сосудистой кальцификации.

Men's and Women's Abuse Talk in Group Therapy: A Discourse Analysis

Subjects: subject: Psychology--Clinical

subject: Intimate partner abuse
subject: Group therapy

description: The creation of therapy groups for men who have been victims of intimate partner abuse, at times controversial, has led to a call for a contextualized understanding of men’s and women’s victimization. The nature, severity, and consequences of abuse are thought to be different for abused men compared to abused women. This project uses a discursive approach to examine how men and women participating in victim therapy groups construct and negotiate abuse accounts and their responses to abuse. My own and other previous research suggests that men in victim therapy groups must shore up their status as victim. This thesis attempts to answer how negotiations of abuse accounts compare between men’s and women’s therapy groups and how responses to abuse accounts compare between the men’s and women’s therapy groups. Two of the Calgary Counselling Centre’s 14-week therapy groups were analyzed using the theoretical and methodological discourse analytic approach: “A Turn for the Better” group for abused men, and “You Are Not Alone” group for abused women. Archived video recordings of these groups were transcribed and analyzed. The women’s and men’s constructions of abuse and the process of negotiating appropriate responses to abuse were qualitatively different. First, the men engaged in extensive rhetorical strategies to position themselves as abused, while the women oriented to safety and protection and their victim status was assumed. Second, the men negotiated the gendered dilemma of responding appropriately to a woman’s aggression without being aggressive in turn, while all women’s responses were constructed as appropriate given their function of protection. Third, for the women, the topic to which everyone oriented, both facilitators and group members, was safety. I also analyzed the therapeutic process in terms of facilitators negotiating men’s accountability for aggression, while women held themselves responsible for morally questionable acts which facilitators tended to endorse as resistance. I address how this study contributes to gender relevance in the therapeutic process of abused men and women, the existing exploratory literature on men’s abuse and therapy, and future clinical practice.

description: В статье приведена история болезни пациента, страдающего осложненной мочекаменной болезнью в сочетании с сердечно-сосудистыми заболеваниями. В течение 14 лет, практически на каждом этапе лечения были допущены ошибки как в обследовании, так и в лечении. На стадии неосложненного уролитиаза не были назначены растворяющие и изгоняющие камни препараты. Присоединение гипертонической болезни и атеросклеротического поражения всего сосудистого русла привело к развитию ишемической болезни сердца, осложненной хронической сердечной недостаточностью, а также к критической ишемии нижних конечностей (больной с промежутком в три года перенес оперативные вмешательства на сосудах обеих нижних конечностей). Не только сочетание нефролитиаза и ишемической болезни сердца, но и неадекватная терапия гипертонической болезни и хронической сердечной недостаточности (лозартан, индапамид), привели к многократным рецидивам уратного камнеобразования хронического пиелонефрита, и, как следствие - к развитию хронической болезни почек. Назначения различных специалистов просто суммировали, не учитывая их фармакологических особенностей и влияния на электролитный баланс и функцию почек. Вывод. При лечении пациентов, страдающих мочекаменной болезнью в сочетании с осложненными сердечно-сосудистыми заболеваниями, необходим строго индивидуальный подход; при подборе лекарственной терапии и урологи, и кардиологи должны действовать совместно, желательно с привлечением клинического фармаколога. Необходим постоянный мониторинг состояния пациентов этой группы, так как патологические процессы взаимно влияют друг на друга, осложняя и усугубляя нарушения функций и почек, и сердца.

description: We give a systematic method for discretizing Hamiltonian partial differential equations (PDEs) with constant symplectic structure, while preserving their energy exactly. The same method, applied to PDEs with constant dissipative structure, also preserves the correct monotonic decrease of energy. The method is illustrated by many examples. In the Hamiltonian case these include: the sine-Gordon, Korteweg-de Vries, nonlinear Schrodinger, (linear) time-dependent Schrodinger, and Maxwell equations. In the dissipative case the examples are: the Allen-Cahn, Cahn-Hilliard, Ginzburg-Landau, and heat equations.

description: The master narrative dominating the field of Canadian art history has continually privileged Eurocentric, colonialist ways of knowing. Many art historians and critics have called for a new story, but nothing to date has been proposed. This dissertation marks the first attempt at re-envisioning the story of art in Canada. It enacts a broader and deeper context of cross-cultural and social-ecological relationships for our art encounters. I discuss conventional cross-cultural approaches to art in Canada and then develop a new approach that I call the storied approach. This approach acknowledges that our art and how we talk about it is, and occurs first within the context of, a story. The storied approach takes seriously that stories animate our lives. It recognizes the performative power of art, and not just its representational quality. It recognizes the phenomenological root of art and story not as the social world alone, but as our more-than-human world within which we circulate. And it draws on the most salient features of postcolonial criticism, while also acknowledging contributions from our colonial past (and present). In this vein, I interweave story and other voices complementing that of the conventional art historian’s/critic’s while, first, bringing the storied approach to bear on the art and criticism of Lucius O’Brien, Tom Thomson and the Group of Seven, and Paul-Émile Borduas. This is not because I consider these three to be the most important artists in Canada, but because these artists have already been privileged as central figures in the current story of Canadian art. Second, I open up the discussion further by attending to the art experiences of various members of an art audience. This allows the stories unfurling through our artworks to breathe in everyday life—the ultimate “story” of art in Canada—from the ground up, here. This larger, living story, we find, is and always has been an indigenously oriented one. European art practices and ideologies have been and are animated by, and nested within, this indigenously oriented story of here, not the other way around.

description: The circulation of pathogens at the wildlife-livestock interface have great consequences for conservation, livestock production and public health. In southwestern Alberta, interactions between cattle and elk (Cervus elaphus) can be opportunities for pathogen transmissions. In this study, we explored the inter-species transmission of livestock pathogens between cattle and elk. Diagnostic tests initially developed for cattle were evaluated and adapted for use in elk. The occurrence of five pathogens (Bovine Herpesvirus 1, Bovine Viral Diarrhoea virus, Mycobacterium avium subsp. paratuberculosis- MAP, Neospora caninum and Fascioloides magna) in geographically overlapping cattle and elk herds was assessed in relation to the pathogen transmission route. Finally, the spatio-temporal patterns of interactions between cattle and elk were described: we first assessed factors influencing the use of cattle pasture by elk, and then defined and measured different types of interactions corresponding to different pathogen characteristics and transmission routes. Only pathogens with indirect transmission routes (MAP, N. caninum, and F. magna) were found in both elk and cattle. Pathogens that persist in the environment, or within intermediate or definitive hosts, may have more opportunities for indirect transmissions, as they do not rely on strict spatio-temporal proximity. This was also illustrated by the increase in interaction rates when the definitions of “interaction” were based on increasing length of pathogen persistence in the environment. Elk avoided cattle presence, except during winter months, possibly increasing direct contacts at this period. When direct contact is necessary for pathogen transmission, specific features of the ranch, such as cultivated hay land, mineral supplements, water sources may also play a critical role by attracting elk on pastures in closer proximity to cattle. This study highlighted the need for the evaluation and validation of diagnostic tools for wildlife species. It contributed to identify the combined effects of pathogen characteristics and inter-species interactions on the transmission of multi-host pathogens. Finally, it identified the benefit of integrating the diversity of pathogen characteristics and life cycles into descriptions of inter-species interaction patterns, and the need for detailed livestock management information to provide reliable assessments of these interactions.
Gamow-Teller strength distribution in proton-rich nucleus $^{57}$Zn and its implications in astrophysics

description: Gamow-Teller (GT) transitions play a preeminent role in the collapse of stellar core in the stages leading to a Type-II supernova. The B(GT) strength distributions for ground and excited states of $^{57}$Zn are calculated in the domain of proton-neutron Quasiparticle Random Phase Approximation (pn-QRPA) theory. No experimental insertions were made (as usually made in other pn-QRPA calculations of B(GT) strength function) to check the performance of the model for proton-rich nuclei. The calculated ground-state B(GT) strength distribution is in good agreement with measurements and shows differences with the earlier reported shell model calculation. The pn-QRPA model reproduced the measured low-lying strength for $^{57}$Zn better in comparison to the KB3G interaction used in the large-scale shell model calculation. The stellar weak rates are sensitive to the location and structure of these low-lying states in daughter $^{57}$Cu. The primary mechanism for producing such nuclei is the rp-process and is believed to be important in the dynamics of the collapsing supermassive stars. Small changes in the binding and excitation energies can lead to significant modifications of the predictions for the synthesis of proton rich isotopes. The $β^{+}$-decay and electron capture (EC) rates on $^{57}$Zn are compared to the seminal work of Fuller, Fowler and Newman (FFN). The pn-QRPA calculated $β^{+}$-decay rates are generally in good agreement with the FFN calculation. However at high stellar temperatures the calculated $β^{+}$-decay rates are almost half of FFN rates. On the other hand, for rp-process conditions, the calculated electron capture ($β^{+}$-decay) rates are bigger than FFN rates by more than a factor 2 (1.5) and may have interesting astrophysical consequences.

description: Using the Canadian Labour Force Survey (2006-2012), I examine the prevalence of and trends in precarious employment, comparing recent and established immigrants to their Canadian-born counterparts. I define precarious employment as holding jobs that involve involuntary part-time work, temporary contracts, or multiple job holding. Although current Canadian labour market research views precarious work as a vital part of that country’s employment outlook (see Krahn, 1995; Vosko et al, 2003; Goldring, 2009; Kapsalis and Tourigny 2004; Zeytinoglu and Cooke 2005) just one Canadian study specifically examines immigrants employed in this type of work (Godin and Renaud, 2005). As a result, my research is unique in examining immigrant participation in non-standard work within Canadian labour markets offering an interdisciplinary approach combining perspectives from sociology and economics. The findings of my research indicate that recent immigrant males and females are overrepresented in involuntary part-time work and this trend is increasing over time. This trend also exists for established immigrants although to a lesser extent. I also observed that recent immigrant women are nearly twice as likely as Canadian-born women to be employed in temporary jobs, net of the controls. For the purposes of further investigation of precarious work among immigrants I expand my research by running multilevel models at individual and CMA levels and find employment in temporary jobs and multiple jobs by both recent and established immigrant males is affected by a CMA’s median hourly earnings as well as the immigrant representation in a CMA. In addition, cross-level interactions reveal that recent male immigrants less likely to be employed in multiple jobs in CMAs in which the median wage is higher. Finally, I use OLS regression to focus on how these types of jobs may lead to lower earnings among these newcomers. I find that recent immigrants are struggling financially due to wage disparities in part created by precarious employment. Both males and females experience an initial earnings disadvantage that is further exacerbated by being employed in involuntary part-time work, temporary work and multiple jobs. Overall, my findings suggest that some form of government intervention is needed through immigration policy reform if Canada values the economic integration of its large immigrant population.

Appointment scheduling with discrete random durations and applications
Creators: name: Begen, Mehmet Atilla
Publisher: name: University of British Columbia
Year: 2010

description: We study scheduling of jobs on a highly utilized resource when the processing durations are stochastic and there are significant underage (resource idle-time) and overage (job waiting and/or resource overtime) costs. Our work is motivated by surgery scheduling and physician appointments. We consider several extensions and applications. In the first manuscript, we determine an optimal appointment schedule (planned start times) for a given sequence of jobs (surgeries) on a single resource (operating room, surgeon). Random processing durations are integers and given by a discrete probability distribution. The objective is to minimize the expected total underage and overage costs. We show that an optimum solution is integer and can be found in polynomial time. In the second manuscript, we consider the appointment scheduling problem under the assumption that the duration probability distributions are not known and only a set of independent samples is available, e.g., historical data. We develop a sampling-based approach and determine bounds on the number of independent samples required to obtain a provably near-optimal solution with high probability. In manuscript three, we focus on determining the number of surgeries for an operating room in an incentive-based environment. We explore the interaction between the hospital and the surgeon in a game theoretic setting, present empirical findings and suggest incentive schemes that the hospital may offer to the surgeon to reduce its idle time and overtime costs. In manuscript four, we consider an application to inventory management in a supply chain context. We introduce advance multi-period quantity commitment with stochastic characteristics (demand or yield) and describe several real-world applications. We show these problems can be solved as special cases of the appointment scheduling problem. In manuscript five, an appendix, we develop an alternate solution approach for the appointment scheduling problem. We find a lower bound value, obtain a subgradient of the objective function, and develop a special-purpose integer rounding algorithm combining discrete convexity and non-smooth convex optimization methods.
Longitudinal and transversal flow over a cavity containing a second immiscible fluid

Year: 2012

description: An analytical solution for the flow field of a shear flow over a rectangular cavity containing a second immiscible fluid is derived. While flow of a single-phase fluid over a cavity is a standard case investigated in fluid dynamics, flow over a cavity which is filled with a second immiscible fluid, has received little attention. The flow filed inside the cavity is considered to define a boundary condition for the outer flow which takes the form of a Navier slip condition with locally varying slip length. The slip-length function is determined from the related problem of lid-driven cavity flow. Based on the Stokes equations and complex analysis it is then possible to derive a closed analytical expression for the flow field over the cavity for both the transversal and the longitudinal case. The result is a comparatively simple function, which displays the dependence of the flow field on the cavity geometry and the medium filling the cavity. The analytically computed flow field agrees well with results obtained from a numerical solution of the Navier-Stokes equations. The studies presented in this article are of considerable practical relevance, for example for the flow over superhydrophobic surfaces.

description: Cerebral amyloid angiopathy (CAA) refers to the deposition of Abeta (Aβ) peptides in the brains small blood vessels leading to hemorrhagic stroke and cognitive impairment. Aβ is toxic to smooth muscle cells and impairs blood flow regulation. Reduced blood oxygen level dependent (BOLD) signal amplitude in response to a visual fMRI task has recently been implicated as a surrogate marker for impaired vascular reactivity in CAA. There have been no studies investigating how the BOLD amplitude changes in other Aβ diseases that present with CAA (Alzheimer’s disease (AD) or mild cognitive impairment (MCI)), or how it changes over time in CAA. BOLD amplitudes were lowest in CAA compared to controls but were not lower in MCI or AD. BOLD amplitudes decreased over 1-year in CAA but not in controls. These results provide more evidence for the use of BOLD amplitudes as a measure of impaired vascular reactivity in CAA.
HybridTEE: secure and privacy-preserving mobile DNN execution using hybrid trusted execution environment
Creators: name: Gangal, Akshay
Publisher: name: No Publisher Supplied
Year: 2020

description: Deep neural networks (DNNs) have been increasingly adopted in many mobile applications involving security/privacy sensitive data and inference models. Therefore, there is an urgent demand for security and privacy protection of DNN execution on mobile devices. Catering to this demand, hardware-based trusted execution environments (TEEs), such as ARM TrustZone, have recently been considered for secure mobile DNN execution. However, none of the existing attempts of running DNN in TrustZone have been successful due to the stringent resource and performance limitations posed by the mobile TEE. We develop HybridTEE, a novel hardware-based security framework to securely execute DNN in the resource-constrained local TEE (i.e., ARM TrustZone), by offloading a part of the DNN model to a resource-rich remote TEE (i.e., Intel SGX). The key design of HybridTEE is two-fold. First, it strategically divides the DNN model into privacy-aware local (TrustZone) and remote (SGX) partitions by employing two privacy-oriented metrics based on object recognition and Scale Invariant Feature Transform (SIFT). Second, it builds a trustworthy communication channel bridging TrustZone and SGX to enable secure offloading of the DNN model between the two TEEs. Our evaluations based on a prototype implementation of HybridTEE and 4 popular DNN models indicate enhanced security and a 1.75x - 3.5x speedup compared to mobile-only DNN execution without TEE.

description: The formation of non-relativistic collisionless shocks in laboratory with ultrahigh intensity lasers is studied via \emph{ab initio} multi-dimensional particle-in-cell simulations. The microphysics behind shock formation and dissipation, and the detailed shock structure are analyzed, illustrating that the Weibel instability plays a crucial role in the generation of strong subequipartition magnetic fields that isotropize the incoming flow and lead to the formation of a collisionless shock, similarly to what occurs in astrophysical scenarios. The possibility of generating such collisionless shocks in laboratory opens the way to the direct study of the physics associated with astrophysical shocks.

description: Дефект межжелудочковой перегородки (ДМЖП) является достаточно распространенным врожденным пороком сердца (ВПС), который занимает важное место в структуре детской заболеваемости и смертности. Своевременная диагностика позволяет выявить порок, требующий хирургической коррекции, которая наиболее эффективна в первые 2 года жизни ребенка. Правильно выбранная тактика лечения занимает первостепенное значение для предотвращения развития тяжелых респираторных нарушений и приступов сердечной недостаточности. Целью исследования являлось выявление частоты и степени выраженности респираторных и гемодинамических нарушений у новорожденных детей с ДМЖП. Материалы и методы. В статье представлен ретроспективный анализ анамнестических, клиниколабораторных и инструментальных данных 84 историй болезни детей, пролеченных в отделении патологии новорожденных с 2016 по 2018 гг. Областного перинатального центра г. Курска. Пациенты, были разделены на 2 группы: 1 группа - 42 ребенка с ДМЖП, 2 группа - группа контроля. Результаты исследования. По данным результатов УЗИ, в первой группе у 35 (83,3%) исследуемых новорожденных выявлен мышечный ДМЖП, у 7 (16,7%) - перимембранозный. Интерпретируя реанимационные мероприятия, проводимые в родильном зале, установлено, что дети с ДМЖП находились чаще на неинвазивной респираторной поддержке, чем дети из контрольной группы. При оценке респираторных нарушений, по данным рентгенологического исследования, обнаружено, что синдром дыхательных расстройств (СДР) и легочная гипертензия (ЛГ) встречаются чаще в первой группе и составляют, соответственно, 10 (23,8%) и 42 (100%) случаев. Анализируя данные ЭхоКГ выявлено, что средний размер ЛП на 1-7 сут в исследуемой группе составил 11,5 мм, что на 0,8 мм больше, чем в контрольной группе. КДР ЛЖ 1-й группы - 17,2 мм, КСР ЛЖ - 11,0 мм, что превышает аналогичные показатели 2-й группы на 1,3 и 0,8 мм, соответственно. На 14-е сутки в исследуемой группе средний размер ПП составлял 12,9 (на 1,8 мм больше аналогичных параметров из группы контроля), ПЖ - 13,6 (> на 1,0 мм), ЛП - 12,9 (> на 2,2 мм), КДР ЛЖ - 17,5 (> на 1,3) и КСР ЛЖ - 10,9 (> на 0,7 мм). Выводы. Выявлено, что ДМЖП является одним из факторов риска развития гемодинамических и респираторных нарушений у новорожденных детей. СДР и ЛГ являются осложнениями исследуемого порока сердца. При оценке данных УЗИ сердца прослежена динамика увеличения размеров правого предсердия и желудочка, что обусловлено шунтированием крови слева направо.

description: Models of smectic-C liquid crystal elastomers predict that it can display soft elasticity, in which the shape of the elastomer changes at no energy cost. The amplitude of the soft mode and the accompanying shears are dependent on the orientation of the layer normal and the director with respect to the stretch axis. We demonstrate that in some geometries the director is forced to rotate perpendicular to the stretch axis, causing lateral expansion of the sample; a negative Poisson's ratio. Current models do not include the effect of imperfections that must be present in the physical sample. We investigate the effect of a simple model of these imperfections on the soft modes in monodomain smectic-C elastomers in a variety of geometries. When stretching parallel to the layer normal (with imposed strain) the elastomer has a negative stiffness once the director starts to rotate. We show that this is a result of the negative Poisson's ratio in this geometry through a simple scalar model.

description: We have carried out electron energy-loss investigations of the lowest singlet excitons in pentacene at 20 K. Our studies allow to determine the full exciton band structure in the a*,b* reciprocal lattice plane. The lowest singlet exciton can move coherently within this plane, and the resulting exciton dispersion is highly anisotropic. The analysis of the energetically following (satellite) features indicates a strong admixture of charge transfer excitations to the exciton wave function.

description: Background: The pharmaceutical industry has very successfully engaged physicians through supporting medical education, patient care and medical research. New conflict of interest policy has highlighted some of the challenges to these relationships. Objectives: To explore the perceptions that early career psychiatrists (e.g. those within 5 years of entering practice) have regarding their relationship with the pharmaceutical industry. Methods: Data were collected through semi-structured interviews. Data were analysed using a grounded theory methodology. Theory was generated around how applicants experienced, developed perceptions around and managed their relationship with industry. Axial coding was used to generate theory around the core variable mediating the perceptions participants had about the relationship between physicians and industry. Results: Participants described increasing frequency of experiences with industry as they progressed from training to independent practice throughout a variety of contexts. Perceptions around their relationship with industry developed through factors relating to their training environment, physician culture, how industry promotes its products and their own practice of medicine. In managing their relationship with industry, participants would either avoid interactions or engage in behaviours aimed to reduce the risk of becoming influenced by industry. Maintaining one’s professional integrity is the underlying driver managing the relationship between early career psychiatrists and industry. Conclusions: Psychiatrists develop perceptions about industry through experience and observation leading them to develop their own strategies to manage these relationships around the critical need they have to maintain their professional integrity.

description: Advancements in retrieving accessible information have evolved faster in the last few years compared to the decades since the internet's creation. Search engines, like Google, have been the number one way to find relevant data. They have always relied on the user's abilities to find the best information in its billions of links and sources at everybody's fingertips. The advent of large language models (LLMs) has completely transformed the field of information retrieval. The LLMs excel not only at retrieving relevant knowledge but also at summarizing it effectively, making information more accessible and consumable for users. On top of it, the rise of AI Agents has introduced another aspect to information retrieval i.e. dynamic information retrieval which enables the integration of real-time data such as weather forecasts, and financial data with the knowledge base to curate context-aware knowledge. However, despite these advancements the agents remain susceptible to issues of bias and fairness, challenges deeply rooted within the knowledge base and training of LLMs. This study introduces a novel approach to bias-aware knowledge retrieval by leveraging agentic framework and the innovative use of bias detectors as tools to identify and highlight inherent biases in the retrieved content. By empowering users with transparency and awareness, this approach aims to foster more equitable information systems and promote the development of responsible AI.
Robust optimization for forest resources decision-making under uncertainty

description: There is a general consensus that management decisions concerning forest resources are made in an intrinsically uncertain environment. However, decision-making tools used in forest management assume perfect information, leaving decision-makers to explore the most likely scenarios of uncertainty and determine the most reasonable management alternative. Although techniques that explicitly consider uncertainty exist, they increase the complexity of the models hence precluding their application to large-size problems. This dissertation describes the application of robust optimization concepts that explicitly consider uncertainty in forest management problems while keeping the models computationally tractable. By introducing some simplifying assumptions about uncertainty distributions, i.e. independency and uniformity, this approach allows for including uncertainty in many coefficients of the model. The methodology modifies the constraints for which feasibility is desirable and incorporates uncertainty in the technical coefficients by introducing an additional term. This term is an optimization problem in itself that introduces new constraints into the original model and acts as a buffer that guarantees constraint satisfaction for different uncertainty realizations. By changing the value of a robustness parameter, the trade-off between cost and robustness can be analyzed. The performance of this approach is explored through three structurally different problems: (a) a non-spatial harvest scheduling problem with uncertain volume yields and demands, (b) a multi-objective problem with uncertain preferences, and (c) a spatial harvest scheduling and road building problem with uncertain volume yields. Deterministic and robust formulations of these problems are provided and the performance of their solutions is evaluated under simulated scenarios of uncertain data. In all cases, robust decisions are less sensitive to uncertain data and hence protected from the occurrence of infeasibilities, with a modest reduction in the objective function value. Moreover, deterministic and robust decisions greatly differ, suggesting that traditional solutions may require major corrections to adapt to changing future conditions with a consequent decrease in the quality of the decisions. The effect of the methodology assumptions are discussed and future work is suggested.
The Empire at Sunset: Production, Finance, and British Grand Strategy 1941-42

description: The year following the collapse of France was a dark one for Britain. It had become the sole great power resisting the Axis. Whilst lucky to have escaped from Dunkirk with its army, Britain had to leave most of its land-based military equipment behind on the beaches. It found itself fighting not only alone, but starting almost from scratch. The nature of this period of the war, and Britain’s leading role in it, is overshadowed by subsequent British decline and the debate over it. The traditional narrative of the Second World War holds that during 1940-41 Britain was out-produced by Germany and by superior American industrial capacity, allowing America to save the day by supplying its allies and its own forces, with Britain playing an important, secondary role. In fact, Britain’s 1941-42 is a success story—though one with high costs. It was the last time Britain harnessed its strength as the world’s greatest power. Britain knew well that to defeat Nazism, its place in the world must decline, the only question being, how far? To finance the war, Britain liquidated its own assets before Lend-Lease. It passively acquiesced when Canada moved away from the Imperial system. Production from the U.S. was not forthcoming and, even so, Britain sent aid to Russia, which it correctly calculated was the critical theatre of the war. This decision, in turn, damaged the strength of Britain’s own forces in North Africa, and indirectly in Singapore, and sullied its relationship with Australia. Britain’s 1941-42 is, then, a key moment when Britain made bold, costly and ultimately effective sacrifices for the greater good.
