Abstract:
We consider the minimization of the repulsive–attractive power-law interaction energies that occur in many biological and physical situations. We show the existence of global minimizers in the discrete setting and obtain bounds for their supports independently of the number of Dirac deltas in a certain range of exponents. These global discrete minimizers correspond to the stable spatial profiles of flock patterns in swarming models. Global minimizers of the continuum problem are obtained by compactness. We also illustrate our results through numerical simulations.

Abstract:
AbstractIn this paper we study the existence and the dynamics of a very special class of motions, which satisfy a strong global minimization property. More precisely, we call a free time minimizer a curve which satisfies the least action principle between any pair of its points without the constraint of time for the variations. An example of a free time minimizer defined on an unbounded interval is a parabolic homothetic motion by a minimal central configuration. The existence of a large amount of free time minimizers can be deduced from the weak KAM theorem. In particular, for any choice ofx0, there should be at least one free time minimizerx(t)defined for allt≥ 0 and satisfyingx(0)=x0. We prove that such motions are completely parabolic. Using Marchal's theorem we deduce as a corollary that there are no entire free time minimizers, i.e. defined on$\mathbb{R}$. This means that the Mañé set of the NewtonianN-body problem is empty.

Abstract:
AbstractVariational monotone recurrence relations arise in solid state physics as generalizations of the Frenkel–Kontorova model for a ferromagnetic crystal. For such problems, Aubry–Mather theory establishes the existence of ‘ground states’ or ‘global minimizers’ of arbitrary rotation number. A nearest neighbor crystal model is equivalent to a Hamiltonian twist map. In this case, the global minimizers have a special property: they can only cross once. As a non-trivial consequence, every one of them has the Birkhoff property. In crystals with a larger range of interaction and for higher order recurrence relations, the single crossing property does not hold and there can exist global minimizers that are not Birkhoff. In this paper we investigate the crossings of global minimizers. Under a strong twist condition, we prove the following dichotomy: they are either Birkhoff, and thus very regular, or extremely irregular and non-physical: they then grow exponentially and oscillate. For Birkhoff minimizers, we also prove certain strong ordering properties that are well known for twist maps.

Abstract:
It is known that gradient flow in linear neural networks using Euclidean loss almost always avoids critical points that have at least one eigendirection with negative curvature. Using algebraic invariants of the gradient flow we try to prove that the set of all critical points with no second-order curvature (zero Hessian) for arbitrary networks is associated to a subset of the invariants of lower dimension. This would mean that these critical points are almost surely avoided. We show that this holds for networks with $3$ or less hidden layers and a few other special cases. We show by way of explicit counter-example that it is not true for general deep networks.
Det är känt att linjära neurala nätverk med Euklidisk loss-funktion under gradient flow alltid undviker kritiska punkter som har minst en egenriktning med negativ böjning. Med hjälp av algebraiska invarianter till gradient flow försöker vi bevisa att invarianter associerade med kritiska punkter med försvinnande Hessian-matris utgör en algebraisk mängd av lägre dimension. Det skulle innebära att dessa kritiska punkter nästan alltid undviks. Vi visar att för nätverk med $3$ eller färre gömda lager så gäller detta. Vi visar även med explicit motexempel att våran förmodan inte gäller för allmänna djupa nätverk.

Abstract:
Many physical systems are modeled mathematically as variational problems, where the observed configurations are expected to be local or global minimizers of a suitable energy. Such an energy can be very complicated, as well as the physical phenomenon under investigation. Thus, as a starting point, it is useful to focus on some simple models, which however capture the main features. In this thesis we concentrate on two kinds of energies, that can be both viewed as nonlocal variants of the perimeter functional. The nonlocality consists in a bulk term, that in one case is given by an elastic energy, while in the other by a long-range interaction of Coulumbic type. The physical systems modeled by these energies displays a rich variety of observable patterns, as well as the formation of morphological instabilities of interfaces between different phases. These phenomena can be mathematically understood as the competition between the local geometric part of the energy, i.e., the perimeter, and the nonlocal one. Indeed, while the first one prefers configurations in which the interfaces are regular and as small as possible, the latter, instead, favors more irregular and oscillating patterns. Thus, finding global or local minima of these energies is a highly nontrivial task, and indeed many big issues about them are still open. The aim of this thesis is to give a contribution to the investigation of such issues.

In recent years, markets and supply chains have become increasingly global in nature. Increased competition has driven the need for more efficient and cost-effective supply chain strategies and production methods. Firms have effectively used analytical techniques to develop manufacturing and supply chain solutions at the strategic, tactical, and operational levels. One such analytical technique for assisting in the development of a strategic network design is the use of a supply chain network optimization model. As part of this study, a supply chain network optimization model was implemented for use by an undisclosed company. This company is in the middle of a cultural shift in focus, from that of manufacturing for economies of scale to manufacturing in support of an integrated and efficient supply chain. As part of this transition, the company must develop analytical techniques and tools to support decision-making on questions ranging from strategic to operational in nature. The primary question posed in this study is "How can this company assess supply chain strategies with the goal of minimizing total landed cost?" To address this question, and support strategic discussions on the topic, a supply chain network optimization model was developed using the IBM ILOG LogicNet Plus software package. The model addresses this question by outputting a supply chain network design that minimizes the total landed cost of supplying products to customers. Case studies were conducted to demonstrate the model's ability to inform strategic decision-making. Inputs to the comprehensive total landed cost function were manipulated to show the impacts and tradeoffs associated with the various cost components and to assist in finding robust and sustainable solutions.

Abstract:
Swarms of animals exhibit aggregations whose behavior is a challenge for mathematicians to understand. We analyze this behavior numerically and analytically by using the pairwise interaction model known as the Morse potential. Our goal is to prove the global stability of the candidate local minimizer in 1D found in A Primer of Swarm Equilibria. Using the calculus of variations and eigenvalues analysis, we conclude that the candidate local minimizer is a global minimum with respect to all solution smaller than its support. In addition, we manage to extend the global stability condition to any solutions whose support has a single component. We are still examining the local minimizers with multiple components to determine whether the candidate solution is the minimum-energy configuration.

Abstract:
Supply chain leaders in the information technology industry face challenges regarding their ability to mitigate amplified demand and supply variability in a supply chain network--the bullwhip effect--and reduce adverse implications on their component supply chain networks. The purpose of this multiple case study was to explore the strategies supply chain leaders in the United States used to reduce the bullwhip effect. Bullwhip effect theory served as the conceptual framework. Participants in the study were 5 purposefully selected supply chain leaders in the state of Texas who successfully implemented strategies to reduce the bullwhip effect on their networks. Data were collected from semistructured interviews and analysis of documents from the participants' websites. The data were analyzed using the 5 data analysis steps consistent with Yin's approach: collection, stratification, reassembly, interpretation, and conclusion. Four themes emerged from data analysis: (a) collaboration strategy, (b) communication strategy, (c) component shortage reduction strategy, and (d) resource management strategy. Supply chain leaders might use the findings of this study to reduce the bullwhip effect within their networks and improve their profitability. The implications for positive social change include the potential for leaders to improve environmental sustainability by using effective supply chain strategies to reduce the accumulation of excess inventories, reduce transportation fuel usage, and lessen the consumption of natural resources.

Abstract:
Devido aos erros de medida de distância, a posição estimada fornecida por um receptor GPS é imprecisa (30 metros, 2s) para aplicações que requerem precisão de centímetros em tempo real, como o de aproximação e pouso automático para aeronaves com restrição de visibilidade da pista (categoria III). Existem três fontes principais de erros: a) degradação intencional, conhecida como disponibilidade seletiva (SA) que está em processo de desativação desde 2 de maio de 2000; b) diluição da precisão (DOP) que está associada aos efeitos da distribuição geométrica dos satélites em solução de navegação. A posição relativa dos satélites disponível afeta a exatidão das coordenadas do usuário obtidas por um receptor GPS e, c) erro equivalente de distância do usuário (UERE) que é a soma das contribuições de cada fonte de erro associada a cada satélite e com a pseudodistância, e são: erros dos relógios do satélite e do usuário, erros do sistema (efemérides, atrasos devido à ionosfera, atrasos da troposfera, multicaminho e receptor). É necessário ter melhor conhecimento dos fatores desses erros e o modelo que os representa. Parte-se do conhecimento a priori da localização da antena do receptor e da obtenção a posteriori da localização exata dos satélites. Dados coletados das pseudodistâncias foram comparados às reais distâncias, obtendo-se o erro a ser modelado. Devido às características dos dados, séries temporais com estrutura de autocorrelação, levaram ao emprego do modelo ARIMA (AutoRegressive Integrated Moving Average, Autoregressivo Integrado e Médias Moveis) da metodologia de Box & Jenkins. Comprovou-se o bom desempenho do modelo com a redução do erro de cálculo da posição do usuário de 110 metros para 1,29 metros.

Abstract:
Dans cette thèse, nous étudions l'existence, non existence et multiplicité des ondes stationnairesavec les normes prescrites pour deux types d'équations aux dérivées partiellesnon linéaires elliptiques découlant de différents modèles physiques. La stabilité orbitale desondes stationnaires est également étudiée dans certains cas. Les principales méthodes denos preuves sont des arguments variationnels. Les solutions sont obtenues comme pointscritiques de fonctionnelle associée sur une contrainte.La thèse se compose de sept chapitres. Le Chapitre 1 est l'introduction de la thèse. Dansles Chapitres 2 à 4, nous étudions une classe d'équations de Schrödinger-Poisson-Slaternon linéaires. Nous établissons dans le Chapitre 2 des résultats optimaux non existencede solutions d'énergie minimale ayant une norme L2 prescrite. Dans le Chapitre 3, nousmontrons un résultat d'existence de solutions L2 normalisées, dans une cas où la fonctionnelleassociée n'est pas bornée inférieurement sur la contrainte. Nos solutions sonttrouvées comme des points de selle de la fonctionnelle, mais ils correspondent à des solutionsd'énergée minimale. Nous montrons également que les ondes stationnaires associéessont orbitalement instables. Ici, puisque nos points critiques présumés ne sont pas desminimiseurs globaux, il n'est pas possible d'utiliser de façon systématique les méthodesde compacité par concentration développées par P. L. Lions. Ensuite, dans le Chapitre4, nous montrons que sous les hypothèses du Chapitre 3, il existe une infinité de solutionsayant une norme L2 prescrite. Dans les deux chapitres suivants, nous étudions uneclasse d'équations de Schrödinger quasi-linéaires. Des résultats optimaux non existence desolutions d'énergie minimale sont donnés dans le Chapitre 5. Dans le Chapitre 6, nousprouvons l'existence de deux solutions positives ayant une norme donnée. L'une d'elles,relativement à la contrainte L2, est de type point selle. L'autre est un minimum, soit localou global. Le fait que la fonctionnelle naturelle associée à cette équation n'est pas biendéfinie nécessite l'utilisation d'une méthode de perturbation pour obtenir ces deux pointscritiques. Enfin, au Chapitre 7, nous mentionnons quelques questions que cette thèse asoulevées.

Abstract:
This work investigates the application of active noise control (ANC) to speech. ANC has had success reducing tonal noise. In this work, that success was extended to noise that is not completely tonal but has some tonal elements such as speech. Limitations such as causality were established on the active control of human speech. An optimal configuration for control actuators was developed for a sphere using a genetic algorithm. The optimal error sensor location was found from exploring the nulls associated with the magnitude of the radiated pressure with reference to the primary pressure field. Both numerically predicted and experimentally validated results for the attenuation of single frequency tones were shown. The differences between the numerically predicted results for attenuation with a sphere present in the pressure field and monopoles in the free-field are also discussed.The attenuation from ANC of both monotone and natural speech is shown and a discussion about the effect of causality on the results is given. The sentence “Joe took father’s shoe bench out” was used for both monotone and natural speech. Over this entire monotone speech sentence, the average attenuation was 8.6 dB with a peak attenuation of 10.6 dB for the syllable “Joe”. Natural speech attenuation was 1.1 dB for the sentence average with a peak attenuation on the syllable “bench” of 2.4 dB. In addition to the lower attenuation values for natural speech, the pressure level for the word “took” was increased by 2.3 dB. Also, the harmonic at 420 Hz in the word “father’s” of monotone speech was reduced globally up to 20 dB. Based on the results of the attenuation of monotone and natural speech, it was concluded that a reasonable amount of attenuation could be achieved on natural speech if its correlation could approach that of monotone speech.

Abstract:
This chapter identifies and critically examines a standard form of argument for organic and vegan alternatives to industrial agriculture. This argument faces important objections to its empirical premises, to its presumption that there is a single food system that minimizes harm and is best for the environment, and to the presumption that the ethically best food system for us to promote is the one that would be best in ideal theory or the one that would be best from the perspective of our own society. Instead, determining which food system should be promoted arguably requires a complex global, empirical, and ethical integrated assessment that includes a proper accounting for values of global justice in nonideal theory. This proper accounting arguably recommends sustainable intensification of food systems (as it is called in the food-science literature), which is importantly distinct from contemporary systems as well as from organic, local, and/or vegan-centered alternatives.

The chapter focuses on randomized controlled trials as these are the gold-standard trial design, which minimizes confounding due to other factors and enables us to draw conclusions about the effectiveness of the intervention. Other key principles of trial design discussed in the chapter include methods to develop a clearly stated, testable research hypothesis, definition of well-defined outcomes, appropriate choice of the control condition, masking of providers and participants where possible, realistic sample size estimates, and appropriate data monitoring and statistical analysis plans. The chapter also outlines alternatives to the parallel arm superiority trial design, such as equivalence and non-inferiority trials, cross-over, stepped wedge, fixed adaptive, and patient preference trial designs.

Abstract:
In the last several upswings of the world economy, core innovations paired new engines with new fuels: steam engines with coal, internal combustion engines with petroleum, and numerous electricity-driven applications with fossil fuels. In each instance, the new fuels initially were inexpensive, abundant, and incredibly powerful but also damaging to the climate and environment. Now we need to develop engines that can run using decarbonized fuels to minimize CO2 emissions. In this chapter we shift our focus to the implications of carbon-based energy sources, system leadership, and climate change. We first review the evidence for a strong relationship between global warming and fossil fuels and then consider what might be done to forestall the consequences of such a relationship.We then relate macro-level fluctuations in world economic growth to policy responses focusing largely on electricity and transportation.

Abstract:
Mediterranean-type climate (MTC) regions are highlighted in several global analyses of conservation risk and priorities. These regions have undergone high levels of habitat conversion and yet of all terrestrial biomes they have the second lowest level of land protection. With transformation pressures set to continue (Chapter 8), planning for a sustainable conservation future in MTC regions is therefore essential. Conservation activities are represented by a variety of philosophies and motives, partially driven by the underlying differences in transformation drivers and sociopolitical contexts across MTC regions. These activities include investment in, and best-practice management of, protected areas (land sparing), an interdisciplinary focus on integrated management of production landscapes (land sharing; stewardship), as well as ecological restoration to increase habitat, improve connectivity, and provide a hedge against the impacts of future climate change. These responses need to be applied in a strategic, synergistic manner to minimize future biodiversity loss.

Abstract:
A climate crisis and other pressures on planetary ecology are causing profound anxieties. Climate change threatens to trap hundreds of millions of people in dire poverty and to separate further an already deeply divided world. However, a new generation of activists is offering inspiration, serving as a hope-maker. This book offers an accessible and empirically informed philosophical discussion of climate change, global poverty, justice, and the importance of political responses, both internationally and domestically, that offer hope. There are reasons enough to worry that the era of pervasive human planetary impact, the Anthropocene, could produce terrible global injustices and massive environmental destruction. But that need not be so. Since the Industrial Revolution, growth in productive capacity and the struggles to share its benefits widely and in an egalitarian way have made another world possible. We still have reason to hope for a world in which international cooperation to manage Earth systems sustainably prevails, in which the natural treasures of the Earth are valued, in which a vision of prosperity is realized and the scourges of disease, ignorance, and poverty are overcome, in which powerful lobbies defending private interests that threaten sustainability are minimized and contained, and in which democratic politics responding to the values of an educated public prevail. The work of bringing about such a world is the work of mobilizing hope.

Abstract:
The catastrophic risks of pandemics and climate change carry deep uncertainty as to when they will occur, how they will unfold, and how much damage they will do. The most important question is how these risks can be faced to minimize them most. This book draws on the troubled and uneven COVID-19 experience to illustrate the critical need to ramp up resilience rapidly and effectively on a global scale. It exposes parallels between the underutilized measures that governments should have taken to contain the spread of COVID-19—such as early action, cross-border planning, and bolstering emergency preparation—and the steps leaders can take now to mitigate the impacts of climate change. Through practical analyses of current policy and thoughtful guidance for successful climate adaptation, the book reveals that, just as society has transformed itself to meet the challenge of coronavirus, so too will the thinking and policies need to be adapted to combat the ever-increasing threat of climate change.

Abstract:
AbstractIn this chapter, we provide an overview of inventory management within the pharmaceutical industry and how to model and optimize it. Inventory management is a highly relevant topic, as it causes high costs such as holding, shortage, and reordering costs. Especially the event of a stock-out can cause damage that goes beyond monetary damage in the form of lost sales. To minimize those costs is the task of an optimized reorder policy. A reorder policy is optimal when it minimizes the accumulated cost in every situation. However, finding an optimal policy is not trivial. First, the problem is highly stochastic as we need to consider variable demands and lead times. Second, the supply chain consists of several warehouses incl. the factory, global distribution warehouses, and local affiliate warehouses, whereby the reorder policy of each warehouse has an impact on the optimal reorder policy of related warehouses. In this context, we discuss the concept of multi-echelon inventory optimization and a methodology that is capable of capturing both, the stochastic behavior of the environment and how it is impacted by the reorder policy: Markov decision processes (MDPs). On this basis, we introduce the concept, its related benefits and weaknesses of a methodology named Reinforcement Learning (RL). RL is capable of finding (near-) optimal (reorder) policies for MDPs. Furthermore, some simulation-based results and current research directions are presented.

Abstract:
Abstract The use of antibiotics in animal agriculture is steadily increasing, especially in developing countries. The European Union and a handful of developed countries have implemented policies to scale back the use of antibiotics, recognizing its role in the global rise of antibiotic resistance. But many farmers who raise animals live in poor countries without public health regulations, or work for large corporate entities that can move their operations to places with weak regulations. To minimize the careless use of antibiotics around the world, we need multi-lateral coordination between states on some common standards for the use of antibiotics in animals.

Abstract:
Global climate change and warming temperatures represent the greatest future challenge for global food production and quality. In this project, we will define the genetic factors of climate-associated taste deficiencies in carrot. Carrot is considered one of the leading horticultural crops in the world in terms of its nutritional value, health benefits, and unique flavor based on its high content of carotenoids and volatile aroma compounds. In recent years, carrot genotypes of different color with improved nutraceutical attributes have been developed. When exposed to high growth temperatures, carrots develop an undesired harsh and bitter taste caused by the accumulation of terpene metabolites. This taste deficiency represents a quality defect to carrot breeders and large- scale growers and needs to be minimized for successful marketing of carrot crops. Surprisingly, the genetic determinants of bitter and harsh flavor in carrot and their response to temperature stress are not well characterized. We started to elucidate these factors in different carrot cultivars by investigating the biosynthesis of volatile terpenes, which represent the predominant flavor compounds in carrots. Also, up to date we identified and characterized two terpenesynthase enzymes, one of which produces (E)-β- caryophyllene, a major terpene component in carrot root. Both TPSs may contribute to the observed variation in volatile terpene formation.

Full text
Abstract:
Autonomous marine vehicles (AMVs) are typically deployed for long periods of time in the ocean to monitor different physical, chemical, and biological processes. Given their limited energy budgets, it makes sense to consider motion plans that leverage the dynamics of the surrounding flow field so as to minimize energy usage for these vehicles. In this paper, we present two graph search based methods to compute energy optimal paths for AMVs in two-dimensional (2-D) time-varying flows. The novelty of the proposed algorithms lies in a unique discrete graph representation of the 3-D configuration space spanned by the spatio-temporal coordinates. This enables a more efficient traversal through the search space, as opposed to a full search of the spatio-temporal configuration space. Furthermore, the proposed strategy results in solutions that are closer to the global optimal when compared to greedy searches through the spatial coordinates alone. We demonstrate the proposed algorithms by computing optimal energy paths around the Channel Islands in the Santa Barbara bay using time-varying flow field forecasts generated by the Regional Ocean Model System. We verify the accuracy of the computed paths by comparing them with paths computed via an optimal control formulation.

Alestig, Mira. Price Interventions as a Part of Living Income Strategies: Lessons learned from piloting a price premium mechanism for basmati rice farmers in Pakistan. Oxfam, March 2023. http://dx.doi.org/10.21201/2023.621486.

Abstract:
Small-scale farmers produce many globally important products such as rice, cocoa, cotton and vanilla. Poverty is widespread among these farmers, and there is an urgent need to increase their incomes. A living income – what a household needs to afford a decent standard of living for all its members – is a human right. It is increasingly recognized that paying a living income is the responsibility of businesses. Pricing is a vital part part of this, but raising the prices paid to farmers can be complicated, and many companies still treat it with scepticism. This paper presents lessons learned from the piloting of a novel price premium mechanism in Pakistan. The goal of the price intervention, which targeted basmati rice farmers in Punjab province, was to make a meaningful contribution to the incomes of the most vulnerable small-scale farmers, while at the same time identifying appropriate mechanisms to minimize costs to retailers and/or consumers. The pilot indicates that price, in combination with other complementary measures, can effectively contribute to closing the income gap for even the most vulnerable small-scale farmers, but that any mechanism to raise prices must be designed carefully. The intervention was part of the wider GRAISEA programme, which supports farmers and food producers in South-East Asia.

Plant Protection and Quarantine: Helping U.S. Agriculture Thrive--Across the Country and Around the World, 2016 Annual Report. U.S. Department of Agriculture, Animal and Plant Health Inspection Service, March 2017. http://dx.doi.org/10.32747/2017.7207241.aphis.

Abstract:
For Plant Protection and Quarantine (PPQ) and our partners, 2016 was a year of remarkable successes. Not only did we eradicate 10 fruit fly outbreaks, but we also achieved 4 years with zero detections of pink bollworm, moving us one step closer to eradicating this pest from all commercial cotton-growing areas of the continental United States. And when the U.S. corn industry faced the first-ever detection of bacterial leaf streak (Xanthomonas vasicular pv vasculorum), we devised a practical and scientific approach to manage the disease and protect valuable export markets. Our most significant domestic accomplishment this year, however, was achieving one of our agency’s top 10 goals: eliminating the European grapevine moth (EGVM) from the United States. On the world stage, PPQ helped U.S. agriculture thrive in the global market-place. We worked closely with our international trading partners to develop and promote science-based standards, helping to create a safe, fair, and predictable agricultural trade system that minimizes the spread of invasive plant pests and diseases. We reached critical plant health agreements and resolved plant health barriers to trade, which sustained and expanded U.S. export markets valued at more than $4 billion. And, we helped U.S. producers meet foreign market access requirements and certified the health of more than 650,000 exports, securing economic opportunities for U.S. products abroad. These successes underscore how PPQ is working every day to keep U.S. agriculture healthy and profitable.

HIV/AIDS-related stigma and discrimination: A conceptual framework and an agenda for action. Population Council, 2002. http://dx.doi.org/10.31899/hiv2002.1010.

Abstract:
In 1987, Jonathan Mann, then director of the WHO Global Programme on AIDS, identified three phases of the HIV/AIDS epidemic: the epidemic of HIV, the epidemic of AIDS, and the epidemic of stigma, discrimination, and denial. Despite international efforts to tackle HIV/AIDS since then, stigma and discrimination (S&D) remain among the most poorly understood aspects of the epidemic. This poor understanding is due in part to the complexity and diversity of S&D, but also to limitations in current thinking within the field and the inadequacy of available theoretical and methodological tools. This paper proposes a new conceptual framework to help inform thinking about the processes of S&D, about the way these processes relate to HIV/AIDS, and about potential interventions to address S&D and minimize their impact. The paper analyzes the sources of S&D, the ways in which HIV/AIDS-related S&D manifests itself, and the contexts in which HIV/AIDS-related S&D take place; highlights the limitations of current thinking and argues that S&D need to be understood as social rather than individual processes; and identifies an agenda for research and intervention.
