description: We present FRA-Poly, a facial reduction algorithm (FRA) for conic linear programs that is sensitive to the presence of polyhedral faces in the cone. The main goals of FRA and FRA-Poly are the same, i.e., finding the minimal face containing the feasible region and detecting infeasibility, but FRA-Poly treats polyhedral constraints separately. This idea enables us to reduce the number of iterations drastically when there are many linear inequality constraints. The worst case number of iterations for FRA-poly is written in the terms of a "distance to polyhedrality" quantity and provides better bounds than FRA under mild conditions. In particular, in the case of the doubly nonnegative cone, FRA-Poly gives a worst case bound of $n$ whereas the classical FRA is $\mathcal{O}(n^2)$. Of possible independent interest, we prove a variant of Gordan-Stiemke's Theorem and a proper separation theorem that takes into account partial polyhedrality. We provide a discussion on the optimal facial reduction strategy and an instance that forces FRAs to perform many steps. We also present a few applications. In particular, we will use FRA-poly to improve the bounds recently obtained by Liu and Pataki on the dimension of certain affine subspaces which appear in weakly infeasible problems.

Risk-taking activism

Year: 2019

description: The dissertation examines the proliferation of activist initiatives in response to the multiplication and exacerbation of public sexual violence in Egypt following the January 25 Revolution. Drawing on feminist geography, social movement scholarship, affect theory, and critical urban studies, this work revises and complicates feminist scholarship on sexual violence against women in two important ways. First, it decenters the experience of white, middle-class, US/Western European women to examine the embodied and spatial effects of actual and potential sexual violence in Egyptian women’s urban practices. The research pays particular attention to the nexus of gender and class in women’s exposure to a wide range of risks, including—but not limited to—public sexual violence. Second, it analyzes public sexual violence in its specificity, not as a universal or timeless phenomenon but as a form of social action that emerges as a consequence of, and is shaped by, historical processes. Filling a gap in the literature, the project traces the occurrence of public sexual harassment in Cairo back to the late 19th century and situates the appearance of this phenomenon in relation to processes of rural-urban migration, urbanization, modern state formation, and nation building. The dissertation draws upon a number of methods, including (auto)ethnographic observations and in-depth qualitative interviews with members of activist groups and non-activist women conducted in Cairo between 2012 and 2015, as well as content analysis of diverse materials. Through the case study of OpAntiSH and HarassMap, the research examines how these projects of direct action and community intervention promoted horizontal expressions of care and solidarity and forms of collective risk-taking that challenged the logic of sexual governmentality that positions women in public space as simultaneously at risk and a risk. Through the case study of The BuSSy Project and WenDo Egypy, it examines how these initiatives opened up avenues for testifying to the experience of sexual harassment and assault while encouraging alternative performances of femininity in public space. The dissertation discusses the transformative and generative potential of these interventions to produce spaces for intentional acts of risk-taking against the backdrop of the increased securitization and militarization of public space, notably following the 2013 military coup in Egypt.

description: В рамках мониторинга, проводившегося в течение 2001-2017 гг., анализировали микобиоту свежеубранного (1-3 мес. после уборки) зерна пивоваренного ячменя, выращенного в ЦФО РФ. Образцы отбирали из партий, закупленных отечественными солодовенными предприятиями. Было проанализировано 103 образца отечественного ячменя и 11 образцов импортного (для сравнения). Анализ микобиоты зерна проводили по методике, разработанной на основе рекомендаций Микробиологического аналитического комитета Европейской пивоваренной конвенции (EBC). Определяли видовой состав наружной и внутренней (субэпидермальной) микобиоты зерна (%); уровень зараженности образца каждым из видов грибов (%); частоту встречаемости каждого вида (%); инфекционную нагрузку микобиоты (в условных единицах). Было установлено, что всегда присутствовали в каждом образце и могут быть отнесены к облигатной микобиоте следующие виды: Alternaria spp., представленная видами «комплекса A. alternata» или «комплекса A. infectoria»; Bipolaris sorokiniana (телеоморфа - Cochliobolus sativus); Epicoccum nigrum; Cladosporium spp. (виды C. herbarum, реже C. cladosporioides) и Fusarium sporotrichioides. В 2001-2008 гг. доминирующими по уровню зараженности были альтернария (максимум 98 %, среднее 65 %) и биполярис (максимум 98 %, среднее 51 %), причем между уровнем зараженности альтернарией и уровнем зараженности биполярисом отмечено высокое значение отрицательной корреляции (r = -0,92 при n = 38). В 2009-2017 гг. наблюдали существенное снижение зараженности биполярисом (в среднем с 51 до 21 %), тогда как альтернария сохранила и даже усилила свои доминирующие позиции (среднее 77 %). В 2017 г. средний показатель по биполярису снизился до 3 %; в 40 % образцов биполярис вообще отсутствовал. В то же время за 2001-2017 гг. было обнаружено возрастание зараженности эпикокком с 17 в 2001-2008 гг. до 39 %, а в отдельных образцах - до 70 % в 2009-2017 гг. В этом отношении численный состав микобиоты приблизился к таковому импортных ячменей. С 2001 по 2017 гг. произошло вытеснение отечественных сортов пивоваренного ячменя и замена их импортными. Возможно, изменения, произошедшие в составе микобиоты зерна ячменя, определяются сменой сортового материала. Генетические особенности новых сортов обеспечивают иные формы взаимодействия с местной микробиотой. Сравнение биологических особенностей биполяриса и эпикокка, важных в отношении пивоваренного ячменя, позволяет заключить, что изменения, произошедшие в видовом составе микобиоты зерна, следует признать скорее благоприятными.

description: In this work, we derive second-order optimality conditions for nonlinear semidefinite programming (NSDP) problems, by reformulating it as an ordinary nonlinear programming problem using squared slack variables. We first consider the correspondence between Karush-Kuhn-Tucker points and regularity conditions for the general NSDP and its reformulation via slack variables. Then, we obtain a pair of "no-gap" second-order optimality conditions that are essentially equivalent to the ones already considered in the literature. We conclude with the analysis of some computational prospects of the squared slack variables approach for NSDP.

description: We initiate a systematic study of the cohomology of cluster varieties. We introduce the Louise property for cluster algebras that holds for all acyclic cluster algebras, and for most cluster algebras arising from marked surfaces. For cluster varieties satisfying the Louise property and of full rank, we show that the cohomology satisfies the curious Lefschetz property of Hausel and Rodriguez-Villegas, and that the mixed Hodge structure is split over the rationals. We give a complete description of the highest weight part of the mixed Hodge structure of these cluster varieties, and develop the notion of a standard differential form on a cluster variety. We show that the point counts of these cluster varieties over finite fields can be expressed in terms of Dirichlet characters. Under an additional integrality hypothesis, the point counts are shown to be polynomials in the order of the finite field.

description: Статья посвящена проблемам оценки качества столовых виноматериалов, используемых в качестве сырья для производства игристых вин. В статье содержится оценка действующих требований к физико-химическим показателям этих виноматериалов в нормативной документации и обосновывается необходимость введения дополнительных показателей с целью получения готовой продукции высокого качества, а также прогнозирования ее качественных характеристик до этапа вторичного брожения. Приведены данные, полученные в результате ранее проведенных исследований, по влиянию величины окислительно-восстановительного потенциала виноматериала на качество готового игристого вина. Показано, что в зависимости от качественного состава органических кислот и их соотношения в исходном виноматериале, в том числе их несбалансированного состава, возможно изменение вкуса готовых игристых вин, появление шероховатости и посторонних привкусов, что снижает органолептическую оценку продукта. Приведены данные о влиянии концентрации азотистых соединений, в том числе отдельных аминокислот и минерального азота, содержащихся в виноматериале, на процесс вторичного брожения, а также пенистые и игристые свойства готового игристого вина. Показана важность такого физико-химического показателя виноматериала, как динамическая устойчивость двусторонней пленки, величина которого в значительной степени зависит от содержания поверхностно-активных веществ. На основании анализа информационного материала и собственных исследований предложено в качестве объективных критериев оценки столовых виноматериалов для игристых вин использовать дополнительные показатели состава, в том числе значения pH и окислительно-восстановительного потенциала, времени жизни (динамической устойчивости) двусторонней пленки виноматериала, массовых концентраций аминного и аммиачного азота, аминокислот, летучих компонентов, органических кислот, фенольных соединений, глицерина, золы и ее щелочности.

description: We study decentralized optimization and learning problems, where a network of n nodes, such as machines, edge devices, and robot swarms, cooperatively minimizes a finite sum of cost functions by means of local information processing and communication with neighboring nodes. Decentralized optimization has emerged as a promising framework for large-scale machine learning and signal processing problems. It is fundamentally important in scenarios where data samples are geographically distributed and/or centralized data processing is infeasible due to computation and communication overhead or data privacy concerns. Although decentralized optimization has been extensively researched under convexity over the past decade, the field still lacks a sound understanding of how to achieve optimal complexities when the underlying problems of interest become non-convex. In this thesis, we construct provably efficient decentralized stochastic firstorder gradient methods for several important classes of non-convex problems with online or offline data, with the help of gradient tracking and variance reduction techniques. In particular, we prove that the proposed algorithms, in regimes of practical significance, achieve network topology-independent computation complexities that match the centralized lower bounds for the corresponding problem classes. This network topology-independence property further leads to the linear speedup of decentralized stochastic optimization algorithms under arbitrary network topologies, in that, the total number of gradient computations at each node is reduced by a factor of 1/n compared to the centralized optimal algorithms that perform all gradient computations at a single node. We also discuss several techniques to balance the computationcommunication trade-offs in the proposed algorithms. Our algorithmic frameworks and their companion analyses are constructed and developed in a systematic manner and may be generalized to other problems of interest. Extensive numerical experiments with both real and synthetic datasets are included to demonstrate our main theoretical results.

description: In this paper we study non-singular vacuum static space-times with non-zero cosmological constant. We introduce new integral quantities, and under suitable assumptions we prove their monotonicity along the level set flow of the static potential. We then show how to use these properties to derive a number of sharp geometric and analytic inequalities, whose equality case can be used to characterize the rotational symmetry of the underlying static solutions. As a consequence, we are able to prove some new uniqueness statements for the de Sitter and the anti-de Sitter metrics. In particular, we show that the de Sitter solution has the least possible surface gravity among three-dimensional static metrics with connected boundary and positive cosmological constant.

СИНДРОМ ОТМЕНЫ ЭТИЛОВОГО СПИРТА

description: Исследовано влияние комплексных пищевых добавок «Панты марала» и «Кедровник» на токсичность алкогольных напитков. Исследование проводили методом хронической форсированной интоксикации животных (беспородных крыс-самцов) растворами этилового спирта с добавками «Панты марала» и «Кедровник» в сравнении с раствором этилового спирта без добавок («Исходная сортировка»). Оценку проводили на основе специфических показателей синдрома отмены этилового спирта в три временных интервала после последнего введения крысам растворов этанола - 10, 13, 16 ч, а также через 36 ч, когда симптомы отмены предположительно должны быть минимальны или отсутствовать совсем. Каждый из показателей имеет определенный балл, соответствующий тяжести его проявления. Полученные результаты свидетельствуют о наиболее благоприятной динамике снижения показателей синдрома отмены этанола в случае интоксикации животных раствором этанола, содержащим добавку «Кедровник» - к 16 ч суммарный балл показателя составил 0,9±0,9, что достоверно отличалось от данного показателя у животных, интоксицированных раствором этилового спирта без добавок (11,3±2,0). Несколько хуже, но также достоверно по сравнению с «Исходной сортировкой», проявила себя добавка «Панты марала». Выживаемость животных, как в период интоксикации, так и в период отмены этилового спирта, была выше в группах животных, интоксицированных растворами этанола, содержащими указанные добавки по сравнению с «Исходной сортировкой». Таким образом, показано, что растворы этилового спирта, содержащие указанные комплексные добавки, снижают остроту проявления абстинентного синдрома, повышают выживаемость животных и улучшают их физический статус.

description: We present a simple and robust technique to extract kinetic rate models and thermodynamic quantities from single molecule time traces. SMACKS (Single Molecule Analysis of Complex Kinetic Sequences) is a maximum likelihood approach that works equally well for long trajectories as for a set of short ones. It resolves all statistically relevant rates and also their uncertainties. This is achieved by optimizing one global kinetic model based on the complete dataset, while allowing for experimental variations between individual trajectories. In particular, neither a priori models nor equilibrium have to be assumed. The power of SMACKS is demonstrated on the kinetics of the multi-domain protein Hsp90 measured by smFRET (single molecule Förster resonance energy transfer). Experiments in and out of equilibrium are analyzed and compared to simulations, shedding new light on the role of Hsp90's ATPase function. SMACKS pushes the boundaries of single molecule kinetics far beyond current methods.

Ecologies of care

description: This project seeks to reveal and dismantle the many consolidations of power (racial, capital, ethical, affective) that structure and vitalize systems of clinical care in the U.S., both currently and historically. Attending to such consolidations of power exposes the ways in which individual harm and collective crisis function as forms of currency and value in U.S. clinical medicine today. These forms of currency and value are differentially distributed depending on one’s proper relation to the state and to key markers of difference—race in particular. As such, the contemporary sphere of U.S. opioid politics serves as a key backdrop for theorizing racial difference generally and whiteness more specifically as specific kinds of clinical and cultural capital in current systems of care. By examining U.S. opioid politics alongside three keywords – Pain, Crisis, and Recovery—this project ultimately seeks to track the ways in which available mechanisms for recognizing and responding to the supposed “fact” of pain in U.S. clinical medicine have resulted in the un-even enfolding of white bodies into the protective structures of the clinic under false promises of endless re-capacitation, while communities and bodies of color are systematically denied such access. Ethnographic research with participatory, peer-to-peer recovery communities in Franklin County, Massachusetts demonstrates vital alternatives for theorizing and enacting care otherwise by centering those who have largely been excised from institutional and state protection in the work of community-directed healing. Ultimately, this project argues that only by coming to terms with—and by becoming accountable to—the histories of violence and extraction that vitalize and securitize bodies of U.S. clinical power will we be able to imagine and then generate other systems and praxes of well-being and of care moving forward.

description: Bodies of Evidence is a study of the transnational optics of anti-blackness across German and U.S. settler colonial projects, with a particular attention to the afterlives of visual discourses in present-day politics and memory. This dissertation analyzes case studies from the U.S., Germany, and German South West Africa, what is present-day Namibia, to track the trace of settler colonial and racial ideologies across seemingly discrete and ruptural violences. Rather than continue to treat these histories and archives as distinct or hierarchical instances of violence, I argue for the importance of interpreting them as part of a broader, uninterrupted narrative. Bodies of Evidence adopts a transnational scope that places settler colonial violence—including the Herero and Nama genocide in German South West Africa—alongside European genocide, framing these events as part of the same ideological and scopic regime. My interdisciplinary analysis builds upon critical race theory, critical visual studies, postcolonial and Black feminist scholarship, museum studies, biological anthropology, among other interdisciplinary and theoretical threads. I critically interpret visual and material evidence with a methodological emphasis on framing the positionality of the viewer in relation to questions about the gaze and modes of looking. Thinking through the looped gaze, parallactic witnessing, and the ethics of looking, I argue that we can transform the act of looking if we understand how the circulation and containment of colonial violences continue to shape ways of seeing.

description: Independent workers—such as gig workers, online freelancers, or micro-entrepreneurs—take on heightened uncertainty in pursuit of flexible working arrangements. While workers may be independent from organizations’ directive control, a decade of ethnographic studies has highlighted how independent workers—who are digitally distributed in space and time—are in fact interdependent on each other for social, emotional, and material support. To augment workers’ quests for peer support, scholars and practitioners have designed dozens of intricate sociotechnical systems which foster large-scale, online peer support networks. Yet, solely sociotechnical approaches to building peer support systems have failed to create systems which provide inclusive support for this rapidly growing and diverse workforce. In pursuit of universal user adoption, such approaches often overlook existing peer networks which are entirely offline, and the resulting systems are rarely accessible, or desirable, to workers with limited trust in technology or technology literacy. This dissertation presents an approach to building community-based peer support systems for work which bridges two disparate bodies of work: sociotechnical system design and participatory action research. To do so, I followed a participatory action protocol to work with community partners who already fostered networks of peer workers to understand if technological interventions could provide supplemental support. In the case that community partners decided to explore technological supplements for peer support, I followed a co-design software protocol to build peer support systems which were driven by local community needs. The outcomes of this approach included not just peer support systems but also educational materials, in-person workshops, and a novel model of on-demand technical support for system on-boarding and maintenance. I illustrated this approach across two multi-year community partnerships with local hubs for independent workers in Pittsburgh, PA. The resulting three peer systems—Hirepeer, Peerdea and Tech Help Desk—facilitated career, professional, and skill development among independent workers.

description: The human health risks of cadmium (Cd), lead (Pb), and nickel (Ni) in fifty regular and slim cigarette brands available in the Serbian market were evaluated. Distributions on per-cigarette basis concentrations of these metals, as determined by graphite furnace atomic absorption spectrometry, were used as inputs in the probabilistic risk assessment. The contents of these metals in cigarettes varied significantly. Larger quantities of the studied metals were observed in regular cigarettes than in slim cigarettes, but the concentration levels per cigarette tobacco mass were higher in slim cigarettes. The metal concentrations in counterfeit cigarettes were marginally higher than those in authentic brands. Based on the mean concentrations, Pb was the most abundant toxic metal, followed by Ni and Cd. The calculated values of the cumulative hazard index (HI) and incremental lifetime cancer risk (ILCR) indicated a low noncarcinogenic risk and low but not negligible carcinogenic risk from Cd, Pb, and Ni. The mean HI and ILCR values obtained using probabilistic and deterministic approaches were similar. A Monte Carlo simulation was employed to minimize the uncertainty of health risk estimation. The sensitivity analysis revealed that the most influential factor was cigarette mass followed by Cd content.

description: We compute the relative orbifold Gromov-Witten invariants of $[\mathbb{C}^2/\mathbb{Z}_{n+1}]\times \mathbb{P}^1$, with respect to vertical fibers. Via a vanishing property of the Hurwitz-Hodge bundle, 2-point rubber invariants are calculated explicitly using Pixton's formula for the double ramification cycle, and the orbifold quantum Riemann-Roch. As a result parallel to its crepant resolution counterpart for $\mathcal{A}_n$, the GW/DT/Hilb/Sym correspondence is established for $[\mathbb{C}^2/\mathbb{Z}_{n+1}]$. The computation also implies the crepant resolution conjecture for relative orbifold Gromov-Witten theory of $[\mathbb{C}^2/\mathbb{Z}_{n+1}]\times \mathbb{P}^1$.

description: We introduce \emph{topological density estimation} (TDE), in which the multimodal structure of a probability density function is topologically inferred and subsequently used to perform bandwidth selection for kernel density estimation. We show that TDE has performance and runtime advantages over competing methods of kernel density estimation for highly multimodal probability density functions. We also show that TDE yields useful auxiliary information, that it can determine its own suitability for use, and we explain its performance.

description: The fluoroquinolone ciprofloxacin occurs worldwide in the aquatic environment and has therefore been listed on the 3rd European union watchlist for monitoring. To eliminate sewage and wastewater treatment plants as entry pathways, advanced oxidation processes have been intensely researched. Hence, photolysis at different pH ranges was studied for its capacity to eradicate ciprofloxacin. High-performance liquid chromatography coupled to high-resolution mass spectrometry was used to identify the degradation products and to monitor all compounds. Ecotoxicity was assessed using quantitative structure-activity relationship analysis comprising the Ecological Structure Activity Relationships tool. Two degradation mechanisms were found active: the direct mechanism, i.e. degradation through ultraviolet absorption by the substance, and the indirect mechanism caused by hydroxyl radicals from water photolysis. The radical scavenger tert-butanol and pH variations revealed that the indirect mechanism predominated in general. The direct photo-induced degradation proceeded about 10 times slower. Products could be attributed to the mechanisms. Based on their chemical structures, all identified products were predicted less toxic by quantitative structure-activity relationship than ciprofloxacin. Mechanistic insight suggested that photo-induced advanced oxidation processes proved efficient for ciprofloxacin elimination when generating hydroxyl radicals. Compounds and pH range hampering their occurrence diminish the efficacy of elimination.

description: We prove the homogenization of fully nonlinear parabolic equations with periodic oscillating Dirichlet boundary conditions on certain general prescribed space-time domains. It was proved in [9,10] that for elliptic equations, the homogenized boundary data exists at boundary points with irrational normal directions, and it is generically discontinuous elsewhere. However for parabolic problems, on a flat moving part of the boundary, we prove the existence of continuous homogenized boundary data $\bar{g}$. We also show that, unlike the elliptic case, $\bar{g}$ can be discontinuous even if the operator is rotation/reflection invariant.

description: A compacted binary tree is a graph created from a binary tree such that repeatedly occurring subtrees in the original tree are represented by pointers to existing ones, and hence every subtree is unique. Such representations form a special class of directed acyclic graphs. We are interested in the asymptotic number of compacted trees of given size, where the size of a compacted tree is given by the number of its internal nodes. Due to its superexponential growth this problem poses many difficulties. Therefore we restrict our investigations to compacted trees of bounded right height, which is the maximal number of edges going to the right on any path from the root to a leaf. We solve the asymptotic counting problem for this class as well as a closely related, further simplified class. For this purpose, we develop a calculus on exponential generating functions for compacted trees of bounded right height and for relaxed trees of bounded right height, which differ from compacted trees by dropping the above described uniqueness condition. This enables us to derive a recursively defined sequence of differential equations for the exponential generating functions. The coefficients can then be determined by performing a singularity analysis of the solutions of these differential equations. Our main results are the computation of the asymptotic numbers of relaxed as well as compacted trees of bounded right height and given size, when the size tends to infinity.

description: In this paper we analyze the capacitary potential due to a charged body in order to deduce sharp analytic and geometric inequalities, whose equality cases are saturated by domains with spherical symmetry. In particular, for a regular bounded domain $Ω\subset \mathbb{R}^n$, $n\geq 3$, we prove that if the mean curvature $H$ of the boundary obeys the condition $$ - \bigg[ \frac{1}{\text{Cap}(Ω)} \bigg]^{\frac{1}{n-2}} \leq \frac{H}{n-1} \leq \bigg[ \frac{1}{\text{Cap}(Ω)} \bigg]^{\frac{1}{n-2}} , $$ then $Ω$ is a round ball.

description: Of 47 endocrine-disrupting chemicals (EDCs) collected from literature and related to breast cancer, not all were tested in a toxicity forecaster (ToxCast) program of the US-Environmental Protection Agency (EPA). Therefore, deep learning models based on the toxicity data in that database have been used to predict the molecular toxicity of the untested EDCs. Combined with the values of median lethal doses (LDs), six potential targets of EDCs related to breast cancer have been identified, viz. MYC proto-oncogene, urokinase plasminogen activator receptor (PLAUR), cytochrome P450 4 A 11, nuclear receptor 1 H 2 (NR1H2), peroxisome proliferator-activated receptor alpha (PPARA), and hypoxia-inducible factor 1 alpha (HIF1A).
