description: [FeFe] hydrogenases are biocatalytic model systems for the exploitation and investigation of catalytic hydrogen evolution. Here, we used vibrational spectroscopic techniques to characterize, in detail, redox transformations of the [FeFe] and [4Fe4S] sub-sites of the catalytic centre (H-cluster) in a monomeric [FeFe] hydrogenase. Through the application of low-temperature resonance Raman spectroscopy, we discovered a novel metastable intermediate that is characterized by an oxidized [(FeFeII)-Fe-I] centre and a reduced [4Fe4S](1+) cluster. Based on this unusual configuration, this species is assigned to the first, deprotonated H-cluster intermediate of the [FeFe] hydrogenase catalytic cycle. Providing insights into the sequence of initial reaction steps, the identification of this species represents a key finding towards the mechanistic understanding of biological hydrogen evolution.
Integrating Building Functions into Massive External Walls

description: Well into the twentieth century, brick and stone were the materials used. Bricklaying and stonemasonry were the construction technologies employed for the exterior walls of virtually all major structures. However, with the rise in quality of life, the massive walls alone became incapable of fulfilling all the developed needs. Adjacent systems and layers had then to be attached to the massive layer. Nowadays, the external wall is usually composed of a layered construction. Each external wall function is usually represented by a separate layer or system. The massive layer of the wall is usually responsible for the load-bearing function. Traditional massive external walls vary in terms of their external appearance, their composition and attached layers. However, their design and construction process is usually a repeated process. It is a linear process where each discipline is concerned with a separate layer or system. These disciplines usually take their tasks away and bring them back to be re-integrated in a layered manner. New massive technologies with additional function have recently become available. Such technologies can provide the external wall with other functions in addition to its load-bearing function. The purpose of this research is to map the changes required to the traditional design and construction process when massive technologies with additional function are applied in external walls. Moreover, the research aims at assessing the performance of massive solutions with additional function when compared to traditional solutions in two different contexts, the Netherlands and Egypt. Through the analysis of different additional function technologies in external walls, a guidance scheme for different stakeholders is generated. It shows the expected process changes as related to the product level and customization level. Moreover, the research concludes that the performance of additional insulating technologies, and specifically Autoclaved Aerated Concrete can provide a better construction compared to the traditional external wall construction of the Netherlands and Egypt.

description: In polycrystalline semiconductor absorbers for thin-film solar cells, structural defects may enhance electron-hole recombination and hence lower the resulting energy conversion efficiency. To be able to efficiently design and optimize fabrication processes that result in high-quality materials, knowledge of the nature of structural defects as well as their formation and annihilation during film growth is essential. Here we show that in co-evaporated Cu(In,Ga)Se-2 absorber films the density of defects is strongly influenced by the reaction path and substrate temperature during film growth. A combination of high-resolution electron microscopy, atomic force microscopy, scanning tunneling microscopy, and X-ray diffraction shows that Cu(In,Ga)Se-2 absorber films deposited at low temperature without a Cu-rich stage suffer from a high density of - partially electronically active - planar defects in the {112} planes. Real-time X-ray diffraction reveals that these faults are nearly completely annihilated during an intermediate Cu-rich process stage with [Cu]/([In] + [Ga]) > 1. Moreover, correlations between real-time diffraction and fluorescence analysis during Cu-Se deposition reveal that rapid defect annihilation starts shortly before the start of segregation of excess Cu-Se at the surface of the Cu(In,Ga)Se-2 film. The presented results hence provide direct insights into the dynamics of the film-quality-improving mechanism.
The impact of stellar feedback on the structure, size and morphology of galaxies in Milky Way size dark matter haloes

description: We use cosmological zoom-in simulations of galaxy formation in a Milky Way (MW)-sized halo started from identical initial conditions to investigate the evolution of galaxy sizes, baryon fractions, morphologies and angular momenta in runs with different parameters of the star formation--feedback cycle. Our fiducial model with a high local star formation efficiency, which results in efficient feedback, produces a realistic late-type galaxy that matches the evolution of basic properties of late-type galaxies: stellar mass, disk size, morphology dominated by a kinematically cold disk, stellar and gas surface density profiles, and specific angular momentum. We argue that feedback's role in this success is twofold: (1) removal of low-angular momentum gas and (2) maintaining a low disk-to-halo mass fraction which suppresses disk instabilities that lead to angular momentum redistribution and a central concentration of baryons. However, our model with a low local star formation efficiency, but large energy input per supernova, chosen to produce a galaxy with a similar star formation history as our fiducial model, leads to a highly irregular galaxy with no kinematically cold component, overly extended stellar distribution and low angular momentum. This indicates that only when feedback is allowed to become vigorous via locally efficient star formation in dense cold gas, resulting galaxy sizes, gas/stellar surface density profiles and stellar disk angular momenta agree with observed $z=0$ galaxies.

description: Do sentence meaning and contextual information get integrated in one-step or is the integration of extra-linguistic variables delayed to a second step? There are findings which point in the direction of one-step models of language comprehension. However, as of yet it is unclear to what extent these reflect low-level associations. To investigate this possibility, we manipulated the polarity of the sentences. A negative sentence still includes the critical word but now describes a plausible situation and should thus not lead to comprehension difficulties unless these are based on low-level associations. In two phrasal self-paced reading studies, we found a mismatch effect independent of polarity early on in the sentence on the phrase involving the critical word and the following phrase. An interaction appeared only at the sentence end, reflecting the mismatch effect for affirmative but not for negated sentences on that phrase. These results suggest an early word-based effect. Readers seem not to fully integrate the meaning of a sentence and the extra-linguistic information about a speaker until the end of a sentence – which seem to fit well with two-step models of comprehension. The influence of pragmatic aspects of negation in speaker-based mismatch effects are discussed.
Peer affliation stability, sense of school belonging and academic achievement in early adolescence: does grade configuration matter?
Creators: name: Schmid, Lorrie Ann

Year: 2009

description: This study focused on the middle school transition and how the social world of peers affected the academic world of early adolescents. Specifically, it focused on the transition to middle school and how it might disrupt peer groups and affect academic achievement. This study included three rural samples from different regional studies. Study 1 was an Appalachian sample with a middle school transition while Study 2 was a Midwest sample where some students had a middle school transition and some did not. This research extends the literature on peer group stability by creating a new individual-level peer group stability indicator. Differences in peer stability were found in all three samples. However, mixed results were found for peer stability across time and academic achievement indicators. No significant differences were found by school grade configuration, indicating that the middle school transition in Study 2 did not affect peer group stability.

description: We exploited the high sensitivity of the INTEGRAL IBIS/ISGRI instrument to study the persistent hard X-ray emission of the soft gamma-ray repeater SGR 1900+14, based on ~11.6 Ms of archival data. The 22-150 keV INTEGRAL spectrum can be well fit by a power law with photon index 1.9 +/- 0.3 and flux F_x = (1.11 +/- 0.17)E-11 erg/cm^2/s (20-100 keV). A comparison with the 20-100 keV flux measured in 1997 with BeppoSAX, and possibly associated with SGR 1900+14, shows a luminosity decrease by a factor of ~5. The slope of the power law above 20 keV is consistent within the uncertainties with that of SGR 1806-20, the other persistent soft gamma-ray repeater for which a hard X-ray emission extending up to 150 keV has been reported.

description: We give a simple example of spacetime metric, illustrating that homogeneity and isotropy of space slices at all moments of time is not obligatory lifted to a full system of six Killing vector fields in spacetime, thus it cannot be interpreted as a symmetry of a four dimensional metric. The metric depends on two arbitrary and independent functions of time. One of these functions is the usual scale factor. The second function cannot be removed by coordinate transformations. We prove that it must be equal to zero, if the metric satisfies Einstein's equations and the matter energy momentum tensor is homogeneous and isotropic. A new, equivalent, definition of homogeneous and isotropic spacetime is given.

description: We report on the observation of anti-ferromagnetic correlations of ultracold fermions in a variety of optical lattice geometries that are well described by the Hubbard model, including dimers, 1D chains, ladders, isolated and coupled honeycomb planes, as well as square and cubic lattices. The dependence of the strength of spin correlations on the specific geometry is experimentally studied by measuring the correlations along different lattice tunneling links, where a redistribution of correlations between the different lattice links is observed. By measuring the correlations in a crossover between distinct geometries, we demonstrate an effective reduction of the dimensionality for our atom numbers and temperatures. We also investigate the formation and redistribution time of spin correlations by dynamically changing the lattice geometry and studying the time-evolution of the system. Timescales ranging from a sudden quench of the lattice geometry to an adiabatic evolution are probed.

Is beryllium ultra-depletion in solar-type stars linked to the presence of a white dwarf companion?

description: Abundance studies of solar-type stars revealed a small fraction of objects with extreme depletion of beryllium. We investigate the possible link between the beryllium depletion and the presence of companions. The classical methods (radial velocity, astrometry, imaging) used to search for binary companions were exploited. We also performed a chemical analysis to identify binaries by the alteration in abundances that is produced by the accretion of material lost by a former evolved companion. We found that all the four previously investigated stars that were found to be ultra--depleted in Be are binaries. In two cases the companion is a white dwarf, and in the other two cases the companion might be a white dwarf or a main-sequence star. One new barium star was identified. We speculate that the interaction with the white dwarf progenitor caused an alteration in the abundance pattern of the star, which resulted in severe beryllium depletion. Possible mechanisms such as thermohaline mixing, episodic accretion, and rotational mixing are discussed. We also briefly discuss predictions for validating this scenario

Changes in Infraspinatus Cross-Sectional Area and Echo Intensity in Relation to Scapular Dyskinesis and Overhead Training Volume in Collegiate Volleyball Players
Creators: name: Chase, Kimberly
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: During the pre-season injury risk in volleyball is highest at 6.19 injuries/1000 exposures. Injury to the posterior shoulder, specifically the infraspinatus, has been attributed to repetitive eccentric loading. The high volume of overhead activity in the collegiate volleyball player has been identified is a risk factor for upper extremity injury. Cross sectional area and echo intensity of the infraspinatus muscle were assessed using diagnostic ultrasound to measure muscle damage. Visual observation of scapular dyskinesis was completed at baseline and 24 hours following the pre-season training period to assess changes due to pre-season training volume. Correlations between cross sectional area, echo intensity, scapular dyskinesis, and swing count were also examined to assess relationships between these variables. Acceptable reliability was established for all measurements. This study found no significant outcomes in cross sectional area or echo intensity, in the severity of scapular dyskinesis, or in relationships between the variables of interest.
Urban Form and Greenhouse Gas Emissions

Publisher: name: A+BE | Architecture and the Built Environment

description: The research reported in this dissertation contains three complementary and overlapping parts: One, “findings”: It assesses the factors of urban morphology that contribute to increased rates of greenhouse gas emissions per capita, and the ways they interact. It finds a significant but underrepresented set of factors, distinct from but relating the factors at the individual building scale and the scale of regional transportation systems. Two, “strategies”: It assesses the methodologies by which such findings might be put to use in identifying and achieving reductions through changes in urban design, and proposes new strategies to do so using innovative forms of design decision support tools. Three, “design decision support tools”: It then proposes a specific new technology, namely a new class of open-source scenario-modelling tool, embodied in new prototype software. The tool utilizes a new kind of “federated” web-based wiki technology incorporating design pattern languages, which was developed in collaboration with the software engineer and wiki inventor Ward Cunningham. As part of this research, it has been necessary to examine fundamental methodological questions, and to account for limitations of current data as well as current significant gaps in research. In the process, this research has made a modest contribution to the state of knowledge about additional research needed. For me, this work has also highlighted the need for urgent and effective reforms to current “business as usual” practices. The need is all the more urgent given unprecedented rates of urbanisation – much of it sprawling and resource-inefficient – taking place in many parts of the world today.

description: In this paper we follow the analysis and protocols of recent experiments, combined with simple theory, to arrive at a physical understanding of quasi-condensation in two dimensional Fermi gases. We find that quasi-condensation mirrors Berezinskii-Kosterlitz-Thouless behavior in many ways, including the emergence of a strong zero momentum peak in the pair momentum distribution. Importantly, the disappearance of this quasi-condensate occurs at a reasonably well defined crossover temperature. The resulting phase diagram, pair momentum distribution, and algebraic power law decay are compatible with recent experiments throughout the continuum from BEC to BCS.

description: We investigate the longevity of broad bridge features in position-velocity diagrams that appear as a result of cloud-cloud collisions. Broad bridges will have a finite lifetime due to the action of feedback, conversion of gas into stars and the timescale of the collision. We make a series of analytic arguments with which to estimate these lifetimes. Our simple analytic arguments suggest that for collisions between clouds larger than R~10 pc the lifetime of the broad bridge is more likely to be determined by the lifetime of the collision rather than the radiative or wind feedback disruption timescale. However for smaller clouds feedback becomes much more effective. This is because the radiative feedback timescale scales with the ionising flux Nly as R^{7/4}Nly^{-1/4} so a reduction in cloud size requires a relatively large decrease in ionising photons to maintain a given timescale. We find that our analytic arguments are consistent with new synthetic observations of numerical simulations of cloud-cloud collisions (including star formation and radiative feedback). We also argue that if the number of observable broad bridges remains ~ constant, then the disruption timescale must be roughly equivalent to the collision rate. If this is the case our analytic arguments also provide collision rate estimates, which we find are readily consistent with previous theoretical models at the scales they consider (clouds larger than about 10 pc) but are much higher for smaller clouds.

description: We consider the radiative transport equation in which the time derivative is replaced by the Caputo derivative. Such fractional-order derivatives are related to anomalous transport and anomalous diffusion. In this paper we describe how the time-fractional radiative transport equation is obtained from continuous-time random walk and see how the equation is related to the time-fractional diffusion equation in the asymptotic limit. Then we solve the equation with Legendre-polynomial expansion.

description: We demonstrate and contrast two approaches to the stabilization of qubit entanglement by feedback. Our demonstration is built on a feedback platform consisting of two superconducting qubits coupled to a cavity which are measured by a nearly-quantum-limited measurement chain and controlled by high-speed classical logic circuits. This platform is used to stabilize entanglement by two nominally distinct schemes: a "passive" reservoir engineering method and an "active" correction based on conditional parity measurements. In view of the instrumental roles that these two feedback paradigms play in quantum error-correction and quantum control, we directly compare them on the same experimental setup. Further, we show that a second layer of feedback can be added to each of these schemes, which heralds the presence of a high-fidelity entangled state in realtime. This "nested" feedback brings about a marked entanglement fidelity improvement without sacrificing success probability.

description: A new two-dimensional material, the C$_2$N holey 2D (C$_2$N-$h$2D) crystal, has recently been synthesized. Here we investigate the strain effects on the properties of this new material by first-principles calculations. We show that the material is quite soft with a small stiffness constant and can sustain large strains $\geq 12\%$. It remains a direct gap semiconductor under strain and the bandgap size can be tuned in a wide range as large as 1 eV. Interestingly, for biaxial strain, a band crossing effect occurs at the valence band maximum close to a 8\% strain, leading to a dramatic increase of the hole effective mass. Strong optical absorption can be achieved by strain tuning with absorption coefficient $\sim10^6$ cm$^{-1}$ covering a wide spectrum. Our findings suggest the great potential of strain-engineered C$_2$N-$h$2D in electronic and optoelectronic device applications.

description: ABSTRACT
      Johanna Leigh White: Can an Integrated Corrective Exercise Intervention Mitigate Range of Motion Changes Post High Intensity Exercise in Female Athletes?
      (Under the direction of Darin Padua)
      Decreased range of motion has become a risk factor associated with ACL injuries. There is a need for an intervention to improve range of motion post fatigue. The purpose of this study is to determine if a corrective exercise intervention helps mitigate lower extremity range of motion post an acute high intensity exercise exposure, and determine if there is a change in range of motion post an acute high intensity exercise exposure. 20 healthy, physically active females between 18-24 years old were randomized to control or treatment groups. Session I subjects had measurements taken, exposed to high intensity exercise and measurements taken post. At 24 hours subjects had measurements taken before and after intervention. Time pre-intervention to post-intervention hamstring showed a significant change (p = .047) in the intervention group. From baseline to post fatigue, 24 hours post fatigue there was a significant decrease in hamstring motion (p = .021).

It is shown that while temperature has no remarkable effect on the strain tensor, the band gap lowers and the radiation wavelength elongates by rising temperature. Also, band-gap and laser energy do not linearly decrease by temperature rise. Our results appear to coincide with former researches.

description: Materials harboring exotic quasiparticles, such as Dirac and Weyl fermions\cite{xu2015discovery,borisenko2015time,weng2015weyl,xu2015observation}, have garnered much attention from the physics and material science communities. These fermions are massless and, in some materials, have shown exceptional physical properties such as ultrahigh mobility and extremely large magnetoresistances \cite{liang2015ultrahigh,ali2014large,du2015unsaturated,shekhar2015large}. Recently, new materials have been predicted to exist which exhibit line nodes of Dirac cones \cite{PhysRevLett.115.036806,xie2015new,burkov2011topological,rhim2015landau}. Here, we show with angle resolved photoemission studies supported by \textit{ab initio} calculations that the highly stable, non-toxic and earth-abundant material, ZrSiS, has an electronic band structure that hosts several Dirac cones which form a Fermi surface with a diamond-shaped line of Dirac nodes. We also experimentally show, for the first time, that the square Si lattice in ZrSiS is an excellent template for realizing the new types of 2D Dirac cones recently predicted by Young and Kane \cite{young2015dirac} and image an unforseen surface state that arises close to the 2D Dirac cone. Finally, we find that the energy range of the linearly dispersed bands is as high as 2\,eV above and below the Fermi level; much larger than of any known Dirac material so far. This makes ZrSiS a very promising candidate to study the exotic behavior of Dirac electrons, or Weyl fermions if a magnetic field is applied, as well as the properties of lines of Dirac nodes

description: A first experimental test of tracking relativistic charged particles by `drifting' Cherenkov photons in a water-based optical time-projection chamber (OTPC) has been performed at the Fermilab Test Beam Facility. The prototype OTPC detector consists of a 77~cm long, 28~cm diameter, 40~kg cylindrical water mass instrumented with a combination of commercial $5.1\times5.1$~cm$^2$ micro-channel plate photo-multipliers (MCP-PMT) and $6.7\times6.7$~cm$^2$ mirrors. Five MCP-PMTs are installed in two columns along the OTPC cylinder in a small-angle stereo configuration. A mirror is mounted opposite each MCP-PMT on the far side of the detector cylinder, effectively doubling the photo-detection efficiency and providing a time-resolved image of the Cherenkov light on the opposing wall. Each MCP-PMT is coupled to an anode readout consisting of thirty 50 Ohm microstrips. A 180-channel data acquisition system digitizes the MCP-PMT signals on one end of the microstrips using the PSEC4 waveform sampling-and-digitizing chip operating at a sampling rate of 10.24~Gigasamples-per-second. The single-ended microstrip readout determines the time and position of a photon arrival at the face of the MCP-PMT by recording both the direct signal and the pulse reflected from the unterminated far end of the strip. The detector was installed on the Fermilab MCenter secondary beam-line behind a steel absorber where the primary flux is multi-GeV muons. Approximately 80 Cherenkov photons are detected for a through-going muon track in a total event duration of ~2 ns. By measuring the time-of-arrival and the position of individual photons at the surface of the detector to $\le$100~ps and a few mm, respectively, we have measured a spatial resolution of $\sim$ 15~mm for each MCP-PMT track segment, and, from linear fits over the entire track length of $\sim40$~cm, an angular resolution on the track direction of $\sim60$~mrad.

description: Archaeological excavations conducted by Vernon J. Knight, Jr. of Mound V's earth lodge complex at the Moundville site, Alabama yielded pottery and stone artifacts that heretofore have been unanalyzed and unreported. For this study, pottery, stone, and architectural analyses were the principal mechanisms used to (1) support the fifteenth-century radiocarbon dates attributed to the Moundville earth lodge complex and (2) describe the architectural components with and features from which the pottery and stone artifacts were associated and recovered. Descriptions and analyses of the complex's artifacts and architecture thus bracketed my consideration of the complex's chronology and function, and its potential significance at a time when Moundville had transitioned from a regional political center to a depopulated necropolis.

description: This article investigates graph analysis for intelligent marketing in smart cities, where metatrails are crowdsourced by mobile sensing for marketing strategies. Unlike most works that focused on client sides, this study is intended for market planning, from the perspective of enterprises. Several novel crowdsourced features based on metatrails, including hotspot networks, crowd transitions, affinity subnetworks, and sequential visiting patterns, are discussed in the article. These smart footprints can reflect crowd preferences and the topology of a site of interest. Marketers can utilize such information for commercial resource planning and deployment. Simulations were conducted to demonstrate the performance. At the end, this study also discusses different scenarios for practical geo-conquesting applications.

description: Due to its complexity, the evolution of cities is something that is difficult to predict and planning new developments for cities is therefore a difficult task. This complexity can be identified on two levels: on a micro level, it emerges from the multiple relations between the many components and actors in cities, whereas on a macro level it stems from the geographical, social and economic relations between cities. However, many of these relations can be measured. The design of plans for cities can only be improved if designers are able to address measurements of some of the relationships between the components of cities during the design process. These measurements are called urban indicators. By calculating such measurements, designers can grasp the meaning of the changes being proposed, not just as simple alternative layouts, but also in terms of the changes in indicators adding a qualitative perception. This thesis presents a method and a set of tools to generate alternative solutions for an urban context. The method proposes the use of a combined set of design patterns encoding typical design moves used by urban designers. The combination of patterns generates different layouts which can be adjusted by manipulating several parameters in relation to updated urban indicators. The patterns were developed from observation of typical urban design procedures, first encoded as discursive grammars and later translated into parametric design patterns. The CItyMaker method and tools allows the designer to compose a design solution from a set of programmatic premises and fine-tune it by pulling parameters whilst checking the changes in urban indicators. These tools improve the designer’s awareness of the consequences of their design moves.

description: Let $ψ_m$ be the smallest strong pseudoprime to the first $m$ prime bases. This value is known for $1 \leq m \leq 11$. We extend this by finding $ψ_{12}$ and $ψ_{13}$. We also present an algorithm to find all integers $n\le B$ that are strong pseudoprimes to the first $m$ prime bases; with a reasonable heuristic assumption we can show that it takes at most $B^{2/3+o(1)}$ time.
Interactions between intracerebral human immunodeficiency virus-1 glycoprotein 120 and systemic heroin on expression of messenger ribonucleic acid (mRNA) of inducible nitric oxide synthase, interleukin-1β, tumor necrosis factor-α, and cyclooxygenase-2 in hippocampus and cortex brain tissue of the Lewis rat

description: Neurological complications caused by interactions of the immune system and the nervous system commonly occur in human immunodeficiency virus patients (HIV). Intravenous drug users, including heroin users, have increased rates of HIV-induced pathology in the brain. Glycoprotein 120 (gp120), a coat protein of HIV, has been implicated as a possible causative factor. These experiments examined an in vivo model of HIV infection in the brain by injecting gp120 into the lateral ventricles of Lewis rats with and without systemic heroin administration. The effects of gp120 and heroin were measured in expression of messenger RNA (mRNA) for the important proinflammatory mediators inducible nitric oxide synthase, interleukin-1β, tumor necrosis factor-α, and cyclooxygenase-2 in hippocampus and cortex tissue. The results of these experiments indicate that heroin may uniquely alter the acute effects of gp120 in the rat brain on mRNA, allowing increased expression of interleukin-1β and inducible nitric oxide mRNA.

description: Homes are renovated a number of times during their lifespan. Although we can regard each of these renovations as new, it is more prudent to implement a future-proof solution to renovation. Current renovation practice focuses on renovating to meet current demand. Many of the renovations are still extremely labour intensive and occur on site. This results in solutions to ensure that the house once again meets the required standards in the short term. These standards will continue to change in the future, however. Our homes will continually require renovation. The question is how we can arrive at solutions that do not impede these future renovations, and implement future-proof solutions that can be applied to a large percentage of housing stock. This study defines future-proof renovation as follows: “Future-proof renovation is renovation that at the very least incorporates solutions that do not impede future renovations and preferably increase opportunities for renovation”. The purpose of this study is to gain an insight into how future-proof renovation solutions are for homes built between 1975 and 1991 that are currently being carried out or offered on the market. The study adopts a primarily architectural viewpoint to examine the hypothesis that we first need to be aware of what is architecturally possible and relevant, before it makes sense to answer any further questions. The key question that this study asks is: What perspective do available renovation concepts offer housing with respect to futureproof renovation? In order to answer this question, this study focuses on developing and applying a method of analysis for these renovation solutions in order to identify the distinctive characteristics that increase the future sustainability of renovation solutions and to evaluate the usability of already developed future-proof renovation solutions for this part of the housing stock. This included seeking inspiration from housing designed using the principles of the Foundation for Architects’ Research (SAR). These homes are constructed according to the support and infill system (SDI homes). This makes it possible to carry out renovations to the infill while the supporting structure remains unchanged. The occupants can then change the infill continually.

description: Η παρούσα εργασία πραγματεύεται το ζήτημα της επιβολής προσωρινής κράτησης στην περίπτωση της συρροής εγκλημάτων. Στο πρώτο σκέλος της εργασίας αναλύεται ο θεσμός της προσωρινής κράτησης και οι προϋποθέσεις επιβολής αυτής. Στο πλαίσιο του δεύτερου σκέλους αυτής αναπτύσσεται η προβληματική της προσωρινής κράτησης στο πεδίο της συρροής εγκλημάτων, όπως αυτή θεσμοθετείται στο άρθρο 293 του Κώδικα Ποινικής Δικονομίας. Ειδικότερα, αναλύεται αρχικά η θεματική της επιβολής προσωρινής κράτησης στο πλαίσιο της αληθινής κατ’ ιδέαν συρροής εγκλημάτων και του κατ’ εξακολούθηση εγκλήματος (άρθρο 293 παρ. 1 ΚΠΔ). Ακολούθως, αναπτύσσεται η θεματική της επιβολής προσωρινής κράτησης στο πεδίο της αληθινής πραγματικής συρροής εγκλημάτων (άρθρο 293 παρ. 2 ΚΠΔ) με ιδιαίτερη έμφαση στις προβληματικές που εγείρει η εν λόγω νομική διάταξη, σε συνδυασμό με τη ρύθμιση του τελευταίου εδαφίου της παρ. 4 του άρθρου 6 του Συντάγματος
description: The present paper deals with the issue of the imposition of provisional detention in the case of concurrent offenses. In the first part of the paper the institution of provisional detention and the prerequisites of its imposition are analyzed. The scope of the second part is the elucidation of the problematics of provisional detention in the field of concurrent offenses as this is enshrined in article 293 of the Criminal Procedure Code. Specifically the thematic of imposition of provisional detention in the framework of ideal concurrence of offenses and serial crime is initially analyzed (CPC article 293 par.1). Subsequently the thematic of imposition of provisional detention in the realm of real concurrence of offenses (CPC article 293 par. 2) is elaborated on, with special emphasis on the problematics raised by said legal provision in conjunction with legislation of the last subparagraph of paragraph 4 article 6 in the Constitution

description: We report optimal and asymptotically optimal reversible circuits composed of NOT, CNOT, and Toffoli (NCT) gates, keeping the count by the subsets of the gate types used. This study fine tunes the circuit complexity figures for the realization of reversible functions via reversible NCT circuits. An important consequence is a result on the limitation of the use of the $T$-count quantum circuit metric popular in applications.

description: The objective of the present document is that of presenting the design of the second version of the PHYSIO DSS component (PHYSIOlogical evolution of the victim Decision Support System), by highlighting the updating with respect to the first version. As already mentioned in deliverable D4.4, efforts in the first year were addressed to the design of the entire structure of the PHYSIO DSS as well as to the implementation in the chosen testing environment (Matlab) of all the functions and algorithms constituting the component. The present deliverable accompanies the second version of the PHYSIO DSS development, based on a client-server architecture provided as Web Services implemented in C++ which represents the programming language in the production environment. The logic of the PHYSIO DSS component has been extensively presented in deliverable D4.4, therefore the document briefly summarises, for completeness, the functions offered as services, neglecting the details that the reader can still access by consulting the D4.4. Section 1 is dedicated to the presentation of the component and of its role in the project. After a general description of the architecture of the PHISIO DSS component and of its functioning, sections 2, 3 and 4 describe the additions and changes in the PHYSIO DSS design compared to the first version. Section two describes the triage algorithms that have been implemented in this second version of the PHYSIO DSS component: the SORT triage, the SIEVE triage, the START and the JUMP START triage. Section 3 presents the changes made to the class of the Health measurements with the aim of integrate the PHYSIO DSS with the current architecture of the CONCORDE platform. Section 4 describes the new logic underlying the influence of the health measurements that are taken in the field on the physiological variables, in the process of determining the a-posteriori distributions of physiological variables and worsening rates.
 Sections 5 briefly describes the table-top demonstration from the PHYSIO DSS point of view, held on February 23rd, whose aim was that of evaluating the Search&Rescue DSS. The table-top was organised in the framework of task T4.6 and the results will be discussed in deliverable D4.13. Section 6 will describe how the PHYSIO DSS will be tested in the Use Case 1 which will be hold in Poggioreale, Sicily (Italy) on April 28th.
