description: This monograph covers some recent advances in a range of acceleration techniques frequently used in convex optimization. We first use quadratic optimization problems to introduce two key families of methods, namely momentum and nested optimization schemes. They coincide in the quadratic case to form the Chebyshev method. We discuss momentum methods in detail, starting with the seminal work of Nesterov and structure convergence proofs using a few master templates, such as that for optimized gradient methods, which provide the key benefit of showing how momentum methods optimize convergence guarantees. We further cover proximal acceleration, at the heart of the Catalyst and Accelerated Hybrid Proximal Extragradient frameworks, using similar algorithmic patterns. Common acceleration techniques rely directly on the knowledge of some of the regularity parameters in the problem at hand. We conclude by discussing restart schemes, a set of simple techniques for reaching nearly optimal convergence rates while adapting to unobserved regularity parameters.

description: We investigate in this article the long-time behaviour of the solutions to the energy-dependant, spatially-homogeneous, inelastic Boltzmann equation for hard spheres. This model describes a diluted gas composed of hard spheres under statistical description, that dissipates energy during collisions. We assume that the gas is "anomalous", in the sense that energy dissipation increases when temperature decreases. This allows the gas to cool down in finite time. We study existence and uniqueness of blow up profiles for this model, together with the trend to equilibrium and the cooling law associated, generalizing the classical Haff's Law for granular gases. To this end, we investigate the asymptotic behaviour of the inelastic Boltzmann equation with and without drift term by introducing new strongly "nonlinear" self-similar variables.

description: The Fermi $γ$-ray space telescope reported the observation of several Galactic supernova remnants recently, with the $γ$-ray spectra well described by hadronic $pp$ collisions. The possible neutrino emissions from these Fermi detected supernova remnants are discussed in this work, assuming the hadronic origin of the $γ$-ray emission. The muon event rates induced by the neutrinos from these supernova remnants on typical km$^3$ neutrino telescopes, such as the IceCube and the KM3NeT, are calculated. The results show that for most of these supernova remnants the neutrino signals are too weak to be detected by the on-going or up-coming neutrino experiment. Only for the TeV bright sources RX J1713.7-3946 and possibly W28 the neutrino signals can be comparable with the atmospheric background in the TeV region, if the protons can be accelerated to very high energies. The northern hemisphere based neutrino telescope might detect the neutrinos from these two sources.

description: Durch die Globalisierung und den fortschreitenden demografischen Wandel kommt

es zu erheblichen Veränderungen in der heutigen industriellen Produktion, innerhalb der Bundesrepublik

Deutschland. Als Folge der zu beobachtenden Entwicklung steigt, durch die stärkere Produktindividualisierung,

der Anteil kleiner Losgrößen stark an. Eine automatisierte Montage ist aufgrund der hohen Flexibilitätsanforderungen

oftmals wirtschaftlich nicht mehr rentabel, wodurch die manuelle Montage wieder

mehr an Bedeutung gewinnt.

Im Folgenden geht es um die Entwicklung und den Einsatz eines geeigneten Montage- und Kommissionierassistenzsystems

für leistungsgeminderte und -gewandelte Mitarbeiter im industriellen Umfeld. Die

Entwicklung dieser neuartigen Montage- und Kommissioniereinrichtung soll die globalen und gesellschaftlich

gewandelten Bedingungen angemessen berücksichtigen, den aktuellen Entwicklungen bzw. deren

Folgen adäquat begegnen und beeinträchtigten Mitarbeitern eine bestmögliche Unterstützung in ihrer

Arbeitstätigkeit bieten.

Zur Ermittlung des Nutzerkreises und der möglichen Bedingungen, die für einen erfolgreichen Einsatz

des Assistenzsystems für die ermittelte Nutzergruppe gegeben sein müssen, wurde eine Datenerhebung in

description: We develop a quantization scheme for Maxwell's equations without source on an arbitrary four dimensional globally hyperbolic spacetime. The field strength tensor is the key dynamical object and it is not assumed a priori that it descends from a vector potential. It is shown that, in general, the associated field algebra can contain a non trivial centre and, on account of this, such a theory cannot be described within the framework of general local covariance unless further restrictive assumptions on the topology of the spacetime are made.

description: Accurate description of finite-temperature vibrational dynamics is indispensable in the computation of two-dimensional electronic spectra. Such simulations are often based on the density matrix evolution, statistical averaging of initial vibrational states, or approximate classical or semiclassical limits. While many practical approaches exist, they are often of limited accuracy and difficult to interpret. Here, we use the concept of thermo-field dynamics to derive an exact finite-temperature expression that lends itself to an intuitive wavepacket-based interpretation. Furthermore, an efficient method for computing finite-temperature two-dimensional spectra is obtained by combining the exact thermo-field dynamics approach with the thawed Gaussian approximation for the wavepacket dynamics, which is exact for any displaced, distorted, and Duschinsky-rotated harmonic potential but also accounts partially for anharmonicity effects in general potentials. Using this new method, we directly relate a symmetry breaking of the two-dimensional signal to the deviation from the conventional Brownian oscillator picture.

Rapid prototyping and analytical tools for CO₂ electrolysis
Creators: name: Wheeler, Danika
Publisher: name: University of British Columbia
Year: 2022

description: The electrochemical conversion of CO₂ into fuels or commodity chemicals is a means to store renewable energy in fuels and chemical products. A CO₂ electrolyzer is an electrochemical flow cell that uses electricity, carbon dioxide, and water to produce carbonaceous products such as carbon monoxide (CO). For electrolytically generated CO to be cost competitive with CO produced by fossil fuel feedstocks, a CO₂ electrolyzer must simultaneously achieve: high product formation rates (current density > 200 mA cm⁻²); high product selectivity (faradaic efficiency > 90%); and high energy efficiency (cell voltage < 3.0 V). An understanding of reaction conditions and an optimization of cell components are needed to achieve these performance targets. This thesis details a method to rapidly prototype electrolyzer flow plates by electroplating 3D printed composite conductive plastic parts. The rapidly prototyped flow plates have comparable performance to an all-metal flow plate at half of the cost and 1/7 of the weight. The prototyping methods were utilized to develop an “analytical electrolyzer” that directly measures fluid conditions within an operating cell. Proof of concept work was completed using a PEM water electrolysis cell. The measured temperature and pressure in the analytical cell were in agreement with literature results and simulations. These methods were then applied to a gas-phase CO₂ electrolyzer to quantify water concentration throughout the cathode compartment. Water is a reactant and integral to CO₂ electrolyzer performance. Humidity and temperature measurements were used to produce a mass transport and fluid flow model of the cathode compartment. The model quantified the method and magnitude by which water enters the cathode compartment. The molar fraction of water at the cathodic GDE/membrane interface remains constant under a range of operating conditions (current density = 25-200 mA cm⁻², flow rate = 25-200 sccm, CO₂ feed humidity = 0% or 70%). An increased water flux across the membrane occurred while operating with dry CO₂ feedstocks at higher flow rates and current densities. The increased water flux across the membrane negatively affected CO₂ electrolyzer performance and stability. The techniques and results reported in this thesis will empower the more thoughtful design of electrolyzer cells.
How Universal is the SFR - H2 Relation?

description: It is a well established empirical fact that the surface density of the star formation rate, Sigma_SFR, strongly correlates with the surface density of molecular hydrogen, Sigma_H2, at least when averaged over large (~kpc) scales. Much less is known, however, if (and how) the Sigma_SFR-Sigma_H2 relation depends on environmental parameters, such as the metallicity or the UV radiation field in the interstellar medium (ISM). Furthermore, observations indicate that the scatter in the Sigma_SFR-Sigma_H2 relation increases rapidly with decreasing averaging scale. How the scale-dependent scatter is generated and how one recovers a tight ~ kpc scale Sigma_SFR-Sigma_H2 relation in the first place is still largely debated. Here, these questions are explored with hydrodynamical simulations that follow the formation and destruction of H2, include radiative transfer of UV radiation, and resolve the ISM on ~60 pc scales. We find that within the considered range of H2 surface densities (10-100 Msun/pc^2) the Sigma_SFR-Sigma_H2 relation is steeper in environments of low metallicity and/or high radiation fields (compared to the Galaxy), that the star formation rate at a given H2 surface density is larger, and the scatter is increased. Deviations from a "universal" Sigma_SFR-Sigma_H2 relation should be particularly relevant for high redshift galaxies or for low-metallicity dwarfs at z~0. We also find that the use of time-averaged SFRs produces a large, scale dependent scatter in the Sigma_SFR-Sigma_H2 relation. Given the plethora of observational data expected from upcoming surveys such as ALMA the scale-scatter relation may indeed become a valuable tool for determining the physical mechanisms connecting star formation and H2 formation.

description: We study a Bose-Hubbard Hamiltonian of ultracold two component gas of spinor Chromium atoms. Dipolar interactions of magnetic moments while tuned resonantly by ultralow magnetic field can lead to spin flipping. Due to approximate axial symmetry of individual lattice site, total angular momentum is conserved. Therefore, all changes of the spin are accompanied by the appearance of the angular orbital momentum. This way excited Wannier states with non vanishing angular orbital momentum can be created. Resonant dipolar coupling of the two component Bose gas introduces additional degree of control of the system, and leads to a variety of different stable phases. The phase diagram for small number of particles is discussed.

Democratic Superstring Field Theory: Gauge Fixing

description: We show that a partial gauge fixing of the NS sector of the democratic-picture superstring field theory leads to the non-polynomial theory. Moreover, by partially gauge fixing the Ramond sector we obtain a non-polynomial fully RNS theory at pictures 0 and 1/2. Within the democratic theory and in the partially gauge fixed theory the equations of motion of both sectors are derived from an action. We also discuss a representation of the non-polynomial theory analogous to a manifestly two-dimensional representation of WZW theory and the action of bosonic pure-gauge solutions. We further demonstrate that one can consistently gauge fix the NS sector of the democratic theory at picture number -1. The resulting theory is new. It is a Z_2 dual of the modified cubic theory. We construct analytical solutions of this theory and show that they possess the desired properties.

description: Game semantics is a denotational semantics presenting compositionally the computational behaviour of various kinds of effectful programs. One of its celebrated achievement is to have obtained full abstraction results for programming languages with a variety of computational effects, in a single framework. This is known as the semantic cube or Abramsky's cube, which for sequential deterministic programs establishes a correspondence between certain conditions on strategies (''innocence'', ''well-bracketing'', ''visibility'') and the absence of matching computational effects. Outside of the sequential deterministic realm, there are still a wealth of game semantics-based full abstraction results; but they no longer fit in a unified canvas. In particular, Ghica and Murawski's fully abstract model for shared state concurrency (IA) does not have a matching notion of pure parallel program-we say that parallelism and interference (i.e. state plus semaphores) are entangled. In this paper we construct a causal version of Ghica and Murawski's model, also fully abstract for IA. We provide compositional conditions parallel innocence and sequentiality, respectively banning interference and parallelism, and leading to four full abstraction results. To our knowledge, this is the first extension of Abramsky's semantic cube programme beyond the sequential deterministic world.

description: Involving consumers in the design, development, and evaluation of consumer informatics interventions is becoming more common and is often used as a quality standard in the field. However, there is wide variability in the degree of consumer involvement in the different stages of the research process, as well as in the methods and frameworks reported and used by authors to involve consumers in the creation of consumer health informatics. Diabetes is an area where consumer health informatics interventions to support self-management have been widely applied. In particular, mobile apps for patients with diabetes have been shown to significantly improve metabolic control (HbA1c), in multiple systematic reviews of RCTs. However, no systematic review has yet characterized consumer involvement in the co-creation (i.e., designing, developing, refining and/or evaluating) of diabetes apps, the methods and frameworks used, and the potential association with clinical outcomes and user engagement. Research questions: 1. How are people with diabetes involved in co-creation (i.e., designing, developing, refining and/or evaluating) smartphone apps (or app interventions) for diabetes self-management? 2. What approaches, methods, or frameworks are used and reported for consumer involvement in the creation process? 3. What is the impact of different levels of consumer involvement in intervention design on health-related outcomes? 4. What is the impact of different levels of consumer involvement in intervention design on user engagement?

description: We analyze the $δ=2$ Tomimatsu-Sato spacetime in the context of the proposed Kerr/CFT correspondence. This 4-dimensional vacuum spacetime is asymptotically flat and has a well-defined ADM mass and angular momentum, but also involves several exotic features including a naked ring singularity, and two disjoint Killing horizons separated by a region with closed timelike curves and a rod-like conical singularity. We demonstrate that the near horizon geometry belongs to a general class of Ricci-flat metrics with $SL(2,\mathbb{R})\times U(1)$ symmetry that includes both the extremal Kerr and extremal Kerr-bolt geometries. We calculate the central charge and temperature for the CFT dual to this spacetime and confirm the Cardy formula reproduces the Bekenstein-Hawking entropy. We find that all of the basic parameters of the dual CFT are most naturally expressed in terms of charges defined intrinsically on the horizon, which are distinct from the ADM charges in this geometry.

Shaping social relations at the grave : a spatial analysis of tombs 88-90 at the Isola Sacra Necropolis and Tomb B at the Vatican Necropolis
Creators: name: Meshel, Elizabeth
Publisher: name: University of British Columbia
Year: 2022

description: Scholars typically consider Roman funerary monuments to be static representations of the commissioner or deceased. However, this common approach limits our inquiries to a single individual and the moment of the tomb's commission, ignoring decades and centuries of subsequent use and users. Furthermore, it belies the fact that the tomb was also a locus of social activity amidst collective mourning and annual festivities like parentalia. To address these shortcomings, this thesis proposes a new approach centered on the agency of the tomb. In so doing, it argues that tombs actively influenced the social activity of its users in ways that changed over time. I employ this approach on two diachronic case studies, Tombs 88-90 at the Isola Sacra Necropolis and Tomb B at the Vatican Necropolis, through an application of space syntax. This analytical framework developed by Hillier and Hanson (1984) permits us to quantify, represent, and interpret the spatial relationships in the built environment that impact the probable movement and encounter patterns of its users. The results of this study reveal that the built environment of the tomb and the material manifestations of its inhabitants structured the social environment of the living as much as it structured their interactions with the dead. Just as relationships amongst the living were not equal, so too were spaces in these chamber tombs. The physical and topological properties of the tomb could reinforce social stratification and create an experiential hierarchy for its users. Consequently, changes to the tomb precipitated not only shifts in its social potential and the lived experience of its users, but also in their experience of social stratification within the space. Finally, this thesis demonstrates that an approach centered on the agency of the tomb can lend new insights into oft-discussed topics and opens the field to new questions, insights, and methodologies that can consider the lifespan of the tomb and the oft-forgotten individuals buried within.

description: We study the optimization landscape of deep linear neural networks with the square loss. It is known that, under weak assumptions, there are no spurious local minima and no local maxima. However, the existence and diversity of non-strict saddle points, which can play a role in first-order algorithms' dynamics, have only been lightly studied. We go a step further with a full analysis of the optimization landscape at order 2. We characterize, among all critical points, which are global minimizers, strict saddle points, and non-strict saddle points. We enumerate all the associated critical values. The characterization is simple, involves conditions on the ranks of partial matrix products, and sheds some light on global convergence or implicit regularization that have been proved or observed when optimizing linear neural networks. In passing, we provide an explicit parameterization of the set of all global minimizers and exhibit large sets of strict and non-strict saddle points.

description: Near a critical point, the time scale of thermally-induced fluctuations diverges in a manner determined by the dynamic universality class. Experiments have verified predicted 3D dynamic critical exponents in many systems, but similar experiments in 2D have been lacking for the case of conserved order parameter. Here we analyze time-dependent correlation functions of a quasi-2D lipid bilayer in water to show that its critical dynamics agree with a recently predicted universality class. In particular, the effective dynamic exponent $z_{\text{eff}}$ crosses over from $\sim 2$ to $\sim 3$ as the correlation length of fluctuations exceeds a hydrodynamic length set by the membrane and bulk viscosities.

description: Natural disaster affects everyone’s lives regardless of position and status in life but its impact can be mitigated by doing necessary preparations. This survey-correlational research design aimed to determine the disaster awareness, preparedness, and resiliency preparation of the 249 randomly selected higher education students from a state university in the province of Aklan. A 3-part researcher-made questionnaire was utilized to gather data about disaster awareness, preparedness, and resiliency preparation. The instruments were subjected to validity and reliability testing. The statistical tools used in data analyses were mean, standard deviation, Analysis of Variance (ANOVA) and Pearson’s r. Inferential test was set at 5% level of significance. The results revealed that the higher education students had high level of disaster awareness. They also had very high level of disaster preparedness, and very high level of disaster resiliency preparation. There is significant variation in the disaster preparedness of the students. There is also significant difference in the disaster resiliency preparation of the students. Moreover, disaster awareness, disaster preparedness, and disaster resiliency preparation are significantly associated.

description: In this paper we study path integral for a single spinless particle on a star graph with N edges, whose vertex is known to be described by U(N) family of boundary conditions. After carefully studying the free particle case, both at the critical and off-critical levels, we propose a new path integral formulation that correctly captures all the scale-invariant subfamily of boundary conditions realized at fixed points of boundary renormalization group flow. Our proposal is based on the folding trick, which maps a scalar-valued wave function on star graph to an N-component vector-valued wave function on half-line. All the parameters of scale-invariant subfamily of boundary conditions are encoded into the momentum independent weight factors, which appear to be associated with the two distinct path classes on half-line that form the cyclic group Z_2. We show that, when bulk interactions are edge-independent, these weight factors are generally given by an N-dimensional unitary representation of Z_2. Generalization to momentum dependent weight factors and applications to worldline formalism are briefly discussed.

description: The mass assembly and star formation histories of massive galaxies identified at low redshift z in different cosmological hydrodynamical simulations, have been studied through a detailed follow-up backwards in time of their constituent mass elements (sampled by particles) of different types. Then, the configurations they depict at progressively higher zs have been analysed. The analyses show that these histories share common generic patterns, irrespective of particular circumstances. In any case, the results we have found are different depending on the particle type. The most outstanding differences follow. We have found that by z ~ 3.5 - 6, mass elements identified as stellar particles at z=0 exhibit a gaseous cosmic-web-like morphology with scales of ~ 1 physical Mpc, where the densest mass elements have already turned into stars by z ~ 6. These settings are in fact the densest pieces of the cosmic web, where no hot particles show up, and dynamically organized as a hierarchy of flow convergence regions, that is, attraction basins for mass flows. On the other hand, mass elements identified at the diffuse hot coronae surrounding massive galaxies at z = 0, do not display a clear web-like morphology at any z. Diffuse gas is heated when flow convergence regions go through contractive deformations, and most of it keeps hot and with low density along the evolution. To shed light on the physical foundations of the behaviour our analyses show up, as well as on their possible observational implications, these patterns have been confronted with some generic properties of singular flows as described by the adhesion model. We have found that these common patterns simulations show can be interpreted as a consequence of flow properties, that, moreover, could explain different generic observational results on massive galaxies or their samples. We briefly discuss some of them.[Abridged]

description: The purpose of this study was to examine the relationships between needs satisfaction measures . and motivational differences for athletes in individual versus team sports using self-determination theory. Participants were 260 college athletes from the University of New Mexico. Needs satisfaction measures predicted intrinsic motivation among both types of athletes. In line with predictions, extrinsic motivation was positively correlated with relatedness and negatively correlated with autonomy. We also found that there was not a relationship between sport and type of motivation, which indicated a similar pattern of motivation for individual versus team athletes.

description: Modeling the chemical, electric, and thermal transport as well as phase transitions and the accompanying mesoscale microstructure evolution within a material in an electronic device setting involves the solution of partial differential equations often with integral boundary conditions. Employing the familiar Poisson equation describing the electric potential evolution in a material exhibiting insulator-to-metal transitions, we exploit a special property of such an integral boundary condition, and we properly formulate the variational problem and establish its well-posedness. We then compare our method with the commonly-used Lagrange multiplier method that can also handle such boundary conditions. Numerical experiments demonstrate that our new method achieves an optimal convergence rate in contrast to the conventional Lagrange multiplier method. Furthermore, the linear system derived from our method is symmetric positive definite, and can be efficiently solved by Conjugate Gradient method with algebraic multigrid preconditioning.

A qualitative study of an emergency department practice pathway from undergraduate nurse to three months post-pathway as new graduate nurse
Creators: name: Bryant, Erin
Publisher: name: University of British Columbia
Year: 2022

description: Background: A health authority, university, and technical institution collaborated to create an Emergency Department (ED) Bachelor of Science in Nursing Practice Pathway. Pathway participants transitioned into the ED as new graduate nurses (NGN). Empirical knowledge related to intentional practice pathways is lacking. The purpose of this study was to investigate the perspectives of NGN who participated in the ED practice pathway and stakeholders involved in pathway development and implementation. Research Design: This study utilized an interpretive description methodology. Data collected occurred through semi-structured interviews with new graduates, a focus group with stakeholders involved in pathway implementation, and new graduate and preceptor completion of Likert-scale assessment tool. Findings: Three main themes were constructed from the data. The first theme, contextual circumstances, represents the circumstances that set the backdrop and influenced NGNs experiences of the pathway and their transition. These circumstances included transitioning during a global pandemic, the culture of nursing burnout, and the learning environment. The second theme, the pathway, reflects NGN participants actual experiences of the pathway overall, as well as its component parts and pathway stakeholders’ perspectives of the overall and specific pathway components. Finally, changes in perceived competence discusses perceived competency of the NGN from both NGN and pathway stakeholder perspectives. Discussion: The findings from the study indicate that NGN who participated in the ED practice pathway experienced enculturation into the ED, a reduction in transition shock, and an accelerated clinical progression. As this was the first study to explore this phenomena, recommendations of future investigation are provided.

description: Decisions to experimentally investigate differentially expressed genes (DEGs) are biased by many factors (e.g., investigator interests, available reagents, knowledge of gene function). The distribution of research on genes is extremely skewed, with the majority of published evidence covering a very small set of genes. Over one-third of all protein-coding genes have no literature coverage or known function. Many disease-associated genes have no published evidence, but may provide important insight when examined within the context of a disease.

Motivation: Utilize publicly available data to identify and annotate the function of uncharacterized PE-associated DEGs

description: U.S. domestic prices for some agricultural commodities sometimes are higher than prices of foreign competing commodities. In such instances the U.S. Government may provide export payment assistance for sales outside of Government programs (commercial sales for dollars) and sales under Government-financed export programs. This article discusses various forms of export payment assistance including payments in cash, payments in kind, and export-payment equivalents (CCC export dispositions below domestic market prices); it enumerates the conditions of eligibility for export payment assistance; and it analyzes by commodity the magnitude of export payment assistance to dollar sales and exports under Government-financed export programs for the year ending June 30, 1962.

description: Young adults exercise for a variety of reasons including fitness, physical attraction, mood improvement, and enjoyment. Research suggests that physical activity may reduce anxiety; people with higher levels of anxiety should be more motivated to exercise to alleviate and reduce their anxiety as well as to improve their overall mood. The purpose of this study was to determine the effects of anxiety level on different types of exercise motivation (ExMot).
Zum Zugstoß der Bewehrung bei Bauwerken der Verkehrsinfrastruktur mit großer Betondeckung

description: Die nach dem derzeit für Ingenieurbauwerke der Verkehrsinfrastruktur in Deutschland gültigen Regelwerk DIN EN 1992-2 und DIN EN 1992-2/NA bemessenen erforderlichen Übergreifungslängen für Betonstahl sind im internationalen Vergleich, vor allem bei kleinen lichten Abständen zwischen den gestoßenen Stäben und großen Stabdurchmessern (Ø ≥ 16mm), mit Abstand am größten. Dies gilt für die unmittelbar benachbarten Länder wie Dänemark, die Niederlande, die Schweiz aber auch beispielsweise die USA. Schäden, die auf die teilweise deutlich geringeren Übergreifungslängen in diesen Ländern zurückzuführen sind, sind nicht bekannt. Die deutschen Regelungen in DIN EN 1992-2/NA sollen nicht nur die Tragfähigkeit, sondern auch die Gebrauchstauglichkeit abdecken. Dabei gehen die deutschen Festlegungen bezüglich der Betondeckung auf der sicheren Seite liegend konservativ von c = 1,0 Ø aus. Der günstige Einfluss einer größeren Betondeckung darf nach Eurocode 2 mit dem Faktor α2 berücksichtigt werden. Dieser Faktor ist nach dem deutschen Nationalen Anhang allerdings generell mit α2 = 1,0 anzusetzen, während er nach Eurocode 2 Werte bis 0,7 annehmen kann. Ein weiterer wesentlicher Unterschied ergibt sich in Abhängigkeit von Stoßanteil und Stabdurchmesser aus dem Stoßfaktor α6 bei kleinen lichten Abständen (a < 8 Ø) zwischen den gestoßenen Stäben. Daher stellt sich die Frage nach einer Überprüfung der im internationalen Vergleich sehr konservativen deutschen Regelungen bei Ingenieurbauwerken mit üblicherweise deutlich größeren Betondeckungen als c = 1,0 Ø, da sich alleine bei Anwendung des Faktors α2 um bis zu 30% kürzere Übergreifungslängen ergeben können. Daraus können unter Umständen ausführungstechnisch und konstruktiv günstigere Bewehrungsanordnungen und teilweise deutliche Kostenreduzierungen infolge des geringeren Materialbedarfs resultieren was sich nicht zuletzt auch hinsichtlich der Ressourceneffizienz vorteilhaft auswirkt. Anhand umfänglicher großformatiger Versuche werden in der Arbeit die derzeit gültigen deutschen konservativen Regelungen sowie die Regelungen im Eurocode 2 analysiert.

description: Background and Purpose—We provide an assessment of clinical, angiographic, and procedure related risk factors associated with stroke and/or death in patients undergoing carotid artery stent placement which will assist in patient stratification and identification of high-stent risk patients. Methods—A comprehensive search of Medline from January 1st 1996 to December 31st 2011 was performed with key words "carotid artery stenosis", " carotid artery stenting", "carotid artery stent placement", "death" , " mortality", "stroke", "outcome", "clinical predictors", "angiographic predictors", was performed in various combinations. We independently abstracted data and assessed the quality of the studies. This analysis led to the selection of 71 articles for review. Results—Clinical factors including age≥80 years, symptomatic status, procedure within 2 weeks of symptoms, chronic renal failure, diabetes mellitus, and hemispheric TIA were associated with stroke (ischemic or hemorrhagic) and death within 1 month after carotid artery stent placement. Angiographic factors including left carotid artery intervention, stenosis > 90%, ulcerated and calcified plaques, lesion length > 10mm, thrombus at the site, ostial involvement, predilation without EPD, ICA-CCA angulation > 60%, aortic arch type III, and aortic arch calcification were also associated with 1 month stroke and/or death. Intra-procedural platelet GP IIb/IIIa inhibitors, protamine use, multiple stents, predilatation prior to stent placement were associated with stroke (ischemic or hemorrhagic) and death after carotid artery stent placement. Intraprocedural use of embolic protection devices and stent design (open versus closed cell design) did not demonstrate a consistent relationship with 1 month stroke and/or death. Procedural statin use, and operator and center experience of more than 50 procedures per year were protective for 1 month stroke and/or death. Conclusions—Our review identified risk factors for stroke, death, and MI within 1 month in patients undergoing carotid artery stent placement. Such information will result in better patient selection for carotid artery stent placement particularly in those who are also candidates for carotid endarterectomy

description: Despite the prior research done in the areas of both exercise and alcohol, there are several gaps in current knowledge. This study was guided by the idea that differing levels of drinking and exercise may have effects on levels of stress as well as cognitive function. The cognitive functions examined in this investigation included short-term memory, attention, concentration and other functions associated with the prefrontal cortex such as inhibition.

The study aimed to make a correlation between drinking and exercise and levels of stress and cognitive function between groups of heavy and light drinkers.
