Abstract:
The endothelial lining of the vasculature is exposed to a large variety of biochemical and hemodynamic stimuli with different gradients throughout the vascular network. Adequate adaptation requires endothelial cells to be highly plastic, which is reflected by the remarkable heterogeneity of endothelial cells in tissues and organs. Hemodynamic forces such as fluid shear stress and cyclic strain are strong modulators of the endothelial phenotype and function. Although endothelial plasticity is essential during development and adult physiology, proatherogenic stimuli can induce adverse plasticity which contributes to disease. Endothelial-to-mesenchymal transition (EndMT), the hallmark of endothelial plasticity, was long thought to be restricted to embryonic development but has emerged as a pathologic process in a plethora of diseases. In this perspective we argue how shear stress and cyclic strain can modulate EndMT and discuss how this is reflected in atherosclerosis and pulmonary arterial hypertension.

Abstract:
Purpose Rising operational costs and software sustainment concerns have driven the Air Force to move to newer technology to ensure that the Air Force Standard Base Supply System (SBSS) can continue to provide affordable and sustainable mission support in the years to come. This paper aims to summarize the successful software modernization effort the Air Force undertook to achieve that objective. Design/methodology/approach The paper describes the preliminary system updates that were required to isolate the SBSS software from all internal and external system and user interfaces in preparation for the subsequent successful code roll effort. Once the legacy SBSS component was fully isolated, the SBSS software modernization objective was achieved via a “code roll” conversion of the SBSS software from legacy COBOL to Java code, and movement of the integrated logistics system-supply application from a proprietary information technology (IT) platform to an open IT operating environment. Findings The SBSS system modernization yielded immediate and significant IT operational cost reductions and provided an important foundation for achieving Air Force logistics system consolidation and cloud computing objectives going forward. Originality/value The SBSS modernization experience should be useful in assisting similar data system software modernization efforts.

Abstract:
In order to analyze the effect of entry strip thickness, entry strip crown and intermediate roll shifting on strip profile and rolling force distribution, a three dimension finite element model of rolls-strip in UCM mill was established and employed. The results showed that the increases of entry strip thickness and entry strip crown would lead to the increase of exit strip crown and edge drop under the same total rolling force; the strip crown and edge drop would be decreased if the intermediate roll shifting δi was decreased. Moreover, the rolling force distribution also was analyzed in details by changing the entry strip thickness, the entry strip crown and the intermediate roll shifting.

Abstract:
The thesis focuses on the shifting mechanisms of manually shifted tractor transmissions. It provides a comprehensive overview of all significant structural nodes of the shift mechanism with an analysis of the influence of the structure on the resulting intensity of a force required for shifting. The main aim of this thesis is the design and validation of experimental equipment for measuring the force effects of the shift mechanism of a mass-produced tractor in actual operation. The design of the experimental equipment is based on a study of the used measuring technique and similar experimental equipment. The final structure is selected based on selection by the method of weighted values, taking into consideration the requirements of the structure. A functional measuring chain is designed and formed for the realization of the measurement. To evaluate the data from the technical experiment, a multibody model of the designed experimental device is created in the MSC Adams View software, through which the real parameters of the shift mechanism are obtained from the measured values. The designed experimental equipment brings the possibility of complete analysis and subsequent optimization of the tractor's shift mechanism

Abstract:
Approved for public release; distribution is unlimited
The role of U.S. Army Special Forces (SF) in the counterproliferation of weapons of mass destruction (WMD) has been minimal in recent years. As globalization leads to increased ability of both states and non-state actors to acquire WMDs, the efforts of Army SF should increase accordingly. Focusing on nuclear weapons, this thesis argues that Army SF elements are ideally positioned to contribute to the counterproliferation mission through the use of the global special operations forces (SOF) network. Utilizing the regional expertise of Army SF and its network of foreign military and government contacts achieved through years of sustained relationships, it serves as an ideal opportunity for strengthening counterproliferation capabilities across the world. Rather than focusing exclusively on the interdiction of WMDs by specialized SOF elements, this thesis recommends shifting to Phase Zero—before WMDs are present—with a focus on building partner capacity to combat WMDs. It examines the adaptation of existing Army SF programs and authorities in order to focus them on WMD and compares this to Army SF augmenting existing non-SOF counterproliferation programs. Finally, it explains how these missions can build relationships within the global SOF network for future operations against proliferators and lead to improved international security.

This thesis will investigate the development of civil-military relations in Brazil since the democratization in 1985. The two most important previous studies, by Alfred Stepan and Wendy Hunter, will be presented and discussed. They where published in 1988 and 1997, respectively. There is therefore a need for a study that includes the development during the long period since these two books were published. The focus will be on three indicators, civilianization of government, how the role of the military has been defined, and military expenditures. The conclusions are that there are contradicting tendencies regarding the development of the civil-military relations, and that the strengthening of civilian institutions is paramount in order to consolidate democracy in Brazil.

Aujourd'hui, les découvertes les plus passionnantes et les réalisations les plus fascinantes se déroulent à la périphérie de différents domaines. Un domaine peu connu qui a récemment démontré des résultats spectaculaires est l'application des principes de l'origami à la science et les technologies modernes. Cette approche présente des avantages qui justifient que l’on s’y attarde. Ce travail de thèse se concentre sur le développement de structures actives à base d’origami à la fois reconfigurables et adaptatives. Nous avons proposé une méthode de synthèse de structures actives à base d’origami. Elle est composée de plusieurs étapes : définition du cahier des charges, création du motif origami en 2D après un choix préalable de la base, conversion en 3D, modélisation multi-physique, choix des technologies de fabrication, intégration de systèmes d’actionnement, validation expérimentale et contrôle. Elle a été suivie du choix des outils logiciels assurant une interopérabilité mutuelle. Elle a ensuite été appliquée et validée pour une application en acoustique. Nous avons alors proposé un concept de résonateurs de Helmholtz adaptatifs à base d’origami pour le contrôle adaptatif-passif du bruit, et nous avons pu obtenir des résultats remarquables en termes de plage de fréquence et de largeur de bande. Un ensemble de modèle a été proposé pour décrire le fonctionnement des résonateurs de Helmholtz adaptatifs à base d’origami suivant leur flexibilité. Nous avons également étudié des actionneurs à base de matériaux actifs pour des structures à base d’origami. Plus précisément les polymères conducteurs qui sont capable de réaliser de grandes déformations à faible tension d’activation pour l’auto-pliage réversible

This approach has advantages that justify the recent attention. This thesis work focuses on the development of origami-based active structures, both reconfigurable and adaptive.

The method was followed by a choice of software tools that ensure mutual interoperability. It was then applied and validated for an acoustics application. A concept of tunable origami-based Helmholtz resonators for adaptive-passive noise control. The resonators were able to achieve remarkable results in terms of frequency range and bandwidth. A set of models has been proposed to describe the functioning of tunable origami-based Helmholtz resonators according to their flexibility.

L'industrie chimique mondiale est en pleine mutation, cherchant des solutions pour rendre la synthèse organique classique plus durable. Une telle solution consiste à passer de la catalyse chimique classique à la biocatalyse. Bien que les avantages des enzymes incluent leur stéréo, régio et chimiosélectivité, cette sélectivité réduit souvent leur promiscuité. Les efforts requis pour adapter la fonction enzymatique aux réactions désirées se sont révélés d'une efficacité modérée, de sorte que des méthodes rapides et rentables sont nécessaires pour générer des biocatalyseurs qui rendront la production chimique plus efficace. Dans l’ère de la bioinformatique et des outils de calcul pour soutenir l'ingénierie des enzymes, le développement rapide de nouvelles fonctions enzymatiques devient une réalité. Cette thèse commence par un examen des développements récents sur les outils de calcul pour l’ingénierie des enzymes. Ceci est suivi par un exemple de l’ingénierie des enzymes purement expérimental ainsi que de l’évolution des protéines. Nous avons exploré l’espace mutationnel d'une enzyme primitive, la dihydrofolate réductase R67 (DHFR R67), en utilisant l’ingénierie semi-rationnelle des protéines. La conception rationnelle d’une librarie de mutants, ou «Smart library design», impliquait l’association covalente de monomères de l’homotétramère DHFR R67 en dimères afin d’augmenter la diversité de la librairie d’enzymes mutées. Le criblage par activité enzymatique a révélé un fort biais pour le maintien de la séquence native dans un des protomères tout en tolérant une variation de séquence élevée pour le deuxième. Il est plausible que les protomères natifs procurent l’activité observée, de sorte que nos efforts pour modifier le site actif de la DHFR R67 peuvent n’avoir été que modérément fructueux. Les limites des méthodes expérimentales sont ensuite abordées par le développement d’outils qui facilitent la prédiction des points chauds mutationnels, c’est-à-dire les sites privilégiés à muter afin de moduler la fonction. Le développement de ces techniques est intensif en termes de calcul, car les protéines sont de grandes molécules complexes dans un environnement à base d’eau, l’un des solvants les plus difficiles à modéliser. Nous présentons l’identification rapide des points chauds mutationnels spécifiques au substrat en utilisant l'exemple d’une enzyme cytochrome P450 industriellement pertinente, la CYP102A1. En appliquant la technique de simulation de la dynamique moléculaire par la force de polarisation adaptative, ou «ABF», nous confirmons les points chauds mutationnels connus pour l’hydroxylation des acides gras tout en identifiant de nouveaux points chauds mutationnels. Nous prédisons également la conformation du substrat naturel, l’acide palmitique, dans le site actif et nous appliquons ces connaissances pour effectuer un criblage virtuel d'autres substrats de cette enzyme. Nous effectuons ensuite des simulations de dynamique moléculaire pour traiter l’impact potentiel de la dynamique des protéines sur la catalyse enzymatique, qui est le sujet de discussions animées entre les experts du domaine. Avec la disponibilité accrue de structures cristallines dans la banque de données de protéines (PDB), il devient clair qu’une seule structure de protéine n’est pas suffisante pour élucider la fonction enzymatique. Nous le démontrons en analysant quatre structures cristallines que nous avons obtenues d’une enzyme β-lactamase, parmi lesquelles un réarrangement important des résidus clés du site actif est observable. Nous avons réalisé de longues simulations de dynamique moléculaire pour générer un ensemble de structures suggérant que les structures cristallines ne reflètent pas nécessairement la conformation de plus basse énergie. Enfin, nous étudions la nécessité de compléter de manière informatisée un hémisphère où l’expérimental n’est actuellement pas possible, à savoir la prédiction de la migration des gaz dans les enzymes. À titre d'exemple, la réactivité des enzymes cytochrome P450 dépend de la disponibilité des molécules d’oxygène envers l’hème du site actif. Par le biais de simulations de la dynamique moléculaire de type Simulation Implicite du Ligand (ILS), nous dérivons le paysage de l’énergie libre de petites molécules neutres de gaz pour cartographier les canaux potentiels empruntés par les gaz dans les cytochromes P450 : CYP102A1 et CYP102A5. La comparaison pour les gaz CO, N2 et O2 suggère que ces enzymes évoluent vers l’exclusion du CO inhibiteur. De plus, nous prédisons que les canaux empruntés par les gaz sont distincts des canaux empruntés par le substrat connu et que ces canaux peuvent donc être modifiés indépendamment les uns des autres.
The chemical industry worldwide is at a turning point, seeking solutions to make classical organic synthesis more sustainable. One such solution is to shift from classical catalysis to biocatalysis. Although the advantages of enzymes include their stereo-, regio-, and chemoselectivity, their selectivity often reduces versatility. Past efforts to tailor enzymatic function towards desired reactions have met with moderate effectiveness, such that fast and cost-effective methods are in demand to generate biocatalysts that will render the production of fine and bulk chemical production more benign. In the wake of bioinformatics and computational tools to support enzyme engineering, the fast development of new enzyme functions is becoming a reality. This thesis begins with a review of recent developments on computational tools for enzyme engineering. This is followed by an example of purely experimental enzyme engineering and protein evolution. We explored the mutational space of a primitive enzyme, the R67 dihydrofolate reductase (DHFR), using semi-rational protein engineering. ‘Smart library design’ involved fusing monomers of the homotetrameric R67 DHFR into dimers, to increase the diversity in the resulting mutated enzyme libraries. Activity-based screening revealed a strong bias for maintenance of the native sequence in one protomer with tolerance for high sequence variation in the second. It is plausible that the native protomers procure the observed activity, such that our efforts to modify the enzyme active site may have been only moderately fruitful. The limitations of experimental methods are then addressed by developing tools that facilitate computational mutational hotspot prediction. Developing these techniques is computationally intensive, as proteins are large molecular objects and work in aqueous media, one of the most complex solvents to model. We present the rapid, substrate-specific identification of mutational hotspots using the example of the industrially relevant P450 cytochrome CYP102A1. Applying the adaptive biasing force (ABF) molecular dynamics simulation technique, we confirm the known mutational hotspots for fatty acid hydroxylation and identify a new one. We also predict a catalytic binding pose for the natural substrate, palmitic acid, and apply that knowledge to perform virtual screening for further substrates for this enzyme. We then perform molecular dynamics simulations to address the potential impact of protein dynamics on enzyme catalysis, which is the topic of heated discussions among experts in the field. With the availability of more crystal structures in the Protein Data Bank, it is becoming clear that a single protein structure is not sufficient to elucidate enzyme function. We demonstrate this by analyzing four crystal structures we obtained of a β-lactamase enzyme, among which a striking rearrangement of key active site residues was observed. We performed long molecular dynamics simulations to generate a structural ensemble that suggests that crystal structures do not necessarily reflect the conformation of lowest energy. Finally, we address the need to computationally complement an area where experimentation is not currently possible, namely the prediction of gas migration into enzymes. As an example, the reactivity of P450 cytochrome enzymes depends on the availability of molecular oxygen at the active-site heme. Using the Implicit Ligand Sampling (ILS) molecular dynamics simulation technique, we derive the free energy landscape of small neutral gas molecules to map potential gas channels in cytochrome P450 CYP102A1 and CYP102A5. Comparison of CO, N2 and O2 suggests that those enzymes evolved towards exclusion of the inhibiting CO. In addition, we predict that gas channels are distinct from known substrate channels and therefore can be engineered independently from one another.

Abstract:
The world that the United Kingdom must face in the late 2010s and into the 2020s seems to make its small armed force look ever smaller, and the gap between the force and intended effect ever wider. This chapter examines the key drivers of UK military operations since the end of the cold war by assessing how the UK has put strategy and doctrine into practice. The Strategic Defence and Security Review 2010 established seven military tasks for the UK armed forces ranging from the defence of the United Kingdom, deterrence of threats, and support for partners through defence engagement, to defence of the overseas territories. However, the review revealed a fundamental tension between ends, ways, and means, a tension also evident in SDSR 2015. The UK’s armed forces are also in transition, shifting away from the land-centric operations of the wars of Yugoslav succession of the mid-1990s to a greater focus on maritime–amphibious operations with an emphasis on deep ‘jointness’ (cross-service cooperation).

Abstract:
AbstractThe specific question this chapter addresses is how to account ethnographically for change that unfolds on spatial and temporal scales larger than those of the ethnographic field study without opposing the local site to global forces. My research engages a processual approach which examines the effects of China’s transformations and the creation of the Shenzhen Special Economic Zone on the relationship between the members of a former emigrant community and their diaspora. I propose an analytical distinction between two relational dimensions of scale in which social action can be considered: scale as the scope of social systems or chains of interdependence that extend in space and time and in which actions and interactions take place, and scale as valence, i.e., the desirability of scale defined relative to other scales, generating “scalar projects.” I focus on how contradictions in the collected field materials are telling signs of accelerated change that generate conflicts of scale, and use such “diagnostic contradictions” as a starting point for understanding how people attempt to make sense of rapid change and reconceptualize the valence of local and global scales.

Abstract:
AbstractThe Republic of Moldova has a long history of shifting borders, and a short history as an independent state. The real development of higher education started only after 1944, in the form of an integral part of the Soviet system of education and research. After independence, its development was shaped strongly by market forces, a demographic decline, alternative study options abroad and last but not least, the all-too-often contradictory policy preferences of changing governments and ministers for education. As a result, on the one hand, the country perpetuated many of the Soviet institutional arrangements in the higher education system, especially the centralised governance arrangements and the academy of science system. On the other hand, the political will to break with the Soviet past and to orientate the country towards Romania and the European Union has spawned a number of policy initiatives, including the ascension to the Bologna Process, greater institutional autonomy, governance democratisation and the implementation of a quality assurance framework along European models. Their implementation, however, has often been hampered by relatively weak institutions and political factionism. As a consequence, the differentiation of the HE system of the Republic of Moldova takes the shape of a dynamic, often contradictory process in which instable institutions are attempting to cope with growing pressures of global, European and local origins.

Abstract:
This paper presents a concept for producing a Statically Balanced Shape-Shifting Surface (SB-SSS). In this context, an SB-SSS is a surface that can require near-zero magnitude force changes to accomplish a change in shape while retaining effectiveness as a physical barrier. This paper focuses on how to statically balance a specifically-designed compliant mechanism and how to incorporate this mechanism into a polygonal cell. The mechanism consists of a compliant Peaucellier-Lipkin linkage layered with a pre-stressed link as the balancer. Prior art is presented that can show how a polygonal cell can be incorporated into a surface via a tiling array. Specifically shaped overlapping thin plates are used to retain the physical barrier requirement. The demonstration of a virtually zero-force Shape-Shifting Surface (SSS) suggests that SSS’s can be designed with a wide range of force-displacement properties, i.e. ranging from that of a square of the parent material to the zero-force mechanism presented here. Applications for an SB-SSS may be macro-scale or micro-scale and may include sensors, biomedical applications, defense applications, and variable stiffness materials.

Abstract:
Discrete Fluid Power Force Systems is one of the topologies gaining focus in the pursuit of lowering energy losses in fluid power transmission systems. The cylinder based Fluid Power Force System considered in this article is constructed with a multi-chamber cylinder, a number of constant pressure lines and a valve manifold. The valve manifold is used to control the connections between the cylinder chambers and the pressure lines and hereby the resulting force form the cylinder. The valve manifold is equipped with fast on/off valves. However, shifting between pressure lines may yield pressure oscillations in the cylinder chamber, especially for systems with long connections between the cylinder and the valve manifold. Hose pressure oscillations will induce oscillations in the produced piston force. Hence, pressure oscillations may increase the fatigue loading on systems employing a discrete fluid power force system. The current paper investigates the correlation between pressure oscillations in the cylinder chambers and valve flow in the manifold. Furthermore, the correlation between the pressure shifting time and the pressure overshoot is investigated. The study therefore focus on how to shape the valve flow in the manifold to reduce the added fatigue loads. A simple transmission line model is developed for the analysis. Two inputs are given in the Laplace domain and the time domain solution of the cylinder pressure to the given inputs are derived through inverse Laplace transformation. Based on the time domain solutions the pressure overshoot for various pressure shifting times is investigated. With the two input functions defined by the pressure shifting time, T, the main results of the current paper show the correlation between the minimum shifting time and the pressure overshoot in a given cylinder chamber with a given line connection.

Abstract:
In secondary valve controlled discrete fluid power force systems the valve opening trajectory greatly influences the pressure dynamics in the actuator chambers. For discrete fluid power systems featuring hoses of significant length pressure oscillations due to fast valve switching is well-known. This paper builds upon theoretical findings on how shaping of the valve opening may reduce the cylinder pressure oscillations. The current paper extents the work by implementing the valve opening characteristics reducing the pressure oscillations on a full scale power take-off test-bench for wave energy converters. Further the energy losses introduced during the shifting period is investigated and compared for two valve opening algorithms. The investigation of the energy loss is utilised to quantify the importance of a fast valve switching and the energy cost of reducing pressure oscillations. The paper will present measurements comparing pressure dynamics for two valve opening algorithms. In addition the paper will give a theoretical investigation of the energy loss during valve shifting and finally measurements of average power output from the power take-off system in various sea states are compared for the three pressure shifting times.

Abstract:
Demands for low cost sustainable solutions have increased the use of and interest in complex hydromechanical transmissions for heavy off-road vehicles. In transmissions with multiple modes, an important condition is to maintain the tractive force during the mode shifting event. For hybrid hydromechanical transmissions, with a direct connection to a hydraulic accumulator, the impressed system pressure caused by the hydraulic accumulator has not yet been observed to interfere with this condition. In this paper, a black box model approach is used to modify the hydraulic system after obtaining knowledge regarding how it is affected by a mode shift. A comparative study is carried out where a full vehicle model of a mobile working machine is simulated with two different hydraulic systems. The results show that different system solutions imply different demands on the included components, and that the mode shifting event is not a negligible factor in heavy hydraulic hybrid vehicles.

Abstract:
Abstract A method for shifting the natural frequency of a damped mechanical system to a desired value is discussed. The solution is derived from the force response equation of the original system. The final equation contains only the degrees of freedom connected to the modifying parameter. Iterations are required but the solution converges rapidly. Modal coupling effects and sensitivity for shifting a frequency are also derived. Modification of stiffness is used as an example for shifting the natural frequency. Numerical results indicate that the method is effective for system dynamics modification.
