description: We use the ultra-deep WFC3/IR data over the HUDF and the Early Release Science WFC3/IR data over the CDF-South GOODS field to quantify the broadband spectral properties of candidate star-forming galaxies at z~7. We determine the UV-continuum slope beta in these galaxies, and compare the slopes with galaxies at later times to measure the evolution in beta. For luminous L*(z=3) galaxies, we measure a mean UV-continuum slope beta of -2.0+/-0.2, which is comparable to the beta~-2 derived at similar luminosities at z~5-6. However, for the lower luminosity 0.1L*(z=3) galaxies, we measure a mean beta of -3.0+/-0.2. This is substantially bluer than is found for similar luminosity galaxies at z~4, just 800 Myr later, and even at z~5-6. In principle, the observed beta of -3.0 can be matched by a very young, dust-free stellar population, but when nebular emission is included the expected beta becomes >~-2.7. To produce these very blue beta's (i.e., beta~-3), extremely low metallicities and mechanisms to reduce the red nebular emission are likely required. For example, a large escape fraction (i.e., f_{esc}>~0.3) could minimize the contribution from this red nebular emission. If this is correct and the escape fraction in faint z~7 galaxies is >~0.3, it may help to explain how galaxies reionize the universe.

description: In the formation process of black holes, the density and temperature of matter become sufficiently high for quarks and pions to appear. In this study we numerically investigate stellar core collapse and black hole formation taking into account the equations of state involving quarks and/or pions. In our simulations, we utilize a code that solves the general relativistic hydrodynamics and neutrino transfer equations simultaneously, treating neutrino reactions in detail under spherical symmetry. Initial models with three different masses, namely, 40, 100 and 375Msolar, are adopted. Our results show that quarks and pions shorten the duration of neutrino emission if the collapse bounces before black hole formation. In addition, pions increase the luminosity and average energy of neutrinos before black hole formation. We also find that the hadron-quark phase transition leads to an interesting evolution of temperature. Moreover, the neutrino event number is evaluated for the currently operating neutrino detector, SuperKamiokande, to confirm that it is not only detectable but also affected by the emergence of quarks and pions for Galactic events. While there are some issues, such as hyperons, beyond the scope of this study, this is the first serious attempt to assess the impact of quarks and pions in dynamical simulations of black hole formation and will serve as an important foundation for future studies.

description: It is shown that statistics of records for time series generated by random walks are independent of the details of the jump distribution, as long as the latter is continuous and symmetric. In N steps, the mean of the record distribution grows as the sqrt(4N/pi) while the standard deviation grows as sqrt((2-4/pi) N), so the distribution is non-self-averaging. The mean shortest and longest duration records grow as sqrt(N/pi) and 0.626508... N, respectively. The case of a discrete random walker is also studied, and similar asymptotic behavior is found.

The QCD corrections to the integrated cross sections are found to be modest, while the shapes of some kinematical distributions change appreciably compared to leading order. The residual scale uncertainties of the next-to-leading order results are at the few-percent level.

description: In percutaneous intervention for treatment of coronary plaques, guidewire navigation is a primary procedure for stent delivery. Steering a flexible guidewire within coronary arteries requires considerable training, and the non-linearity between the control operation and the movement of the guidewire makes precise manipulation difficult. Here, we introduce a deep reinforcement learning(RL) framework for autonomous guidewire navigation in a robot-assisted coronary intervention. Using Rainbow, a segment-wise learning approach is applied to determine how best to accelerate training using human demonstrations with deep Q-learning from demonstrations (DQfD), transfer learning, and weight initialization. `State' for RL is customized as a focus window near the guidewire tip, and subgoals are placed to mitigate a sparse reward problem. The RL agent improves performance, eventually enabling the guidewire to reach all valid targets in `stable' phase. Our framework opens anew direction in the automation of robot-assisted intervention, providing guidance on RL in physical spaces involving mechanical fatigue.

description: Plasma balls and rings emerge as fluid holographic duals of black holes and black rings in the hydrodynamic/gravity correspondence for the Scherk-Schwarz AdS system. Recently, plasma balls spinning above a critical rotation were found to be unstable against m-lobed perturbations. In the phase diagram of stationary solutions the threshold of the instability signals a bifurcation to a new phase of non-axisymmetric configurations. We find explicitly this family of solutions and represent them in the phase diagram. We discuss the implications of our results for the gravitational system. Rotating non-axisymmetric black holes necessarily radiate gravitational waves. We thus emphasize that it would be important, albeit possibly out of present reach, to have a better understanding of the hydrodynamic description of gravitational waves and of the gravitational interaction between two bodies. We also argue that it might well be that a non-axisymmetric m-lobed instability is also present in Myers-Perry black holes for rotations below the recently found ultraspinning instability.

description: Ergothioneine (ET), a dietary thione/thiol, is receiving growing attention for its possible benefits in healthy aging and metabolic resilience. Our study investigates ET’s effects on healthspan in aged animals, revealing lifespan extension and enhanced mobility in Caenorhabditis elegans, accompanied by improved stress resistance and reduced age-associated biomarkers. In aged rats, ET administration enhances exercise endurance, muscle mass, and vascularization, concomitant with higher NAD+ levels in muscle. Mechanistically, ET acts as an alternative substrate for cystathionine gamma-lyase (CSE), stimulating H2S production, which increases protein persulfidation of more than 300 protein targets. Among these, protein-persulfidation-driven activation of cytosolic glycerol-3-phosphate dehydrogenase (cGPDH) primarily contributes to the ET-induced NAD+ increase. ET’s effects are abolished in models lacking CSE or cGPDH, highlighting the essential role of H2S signaling and protein persulfidation. These findings elucidate ET’s multifaceted actions and provide insights into its therapeutic potential for combating age-related muscle decline and metabolic perturbations.
Bosons, fermions and anyons in the plane, and supersymmetry

description: Universal vector wave equations allowing for a unified description of anyons, and also of usual bosons and fermions in the plane are proposed. The existence of two essentially different types of anyons, based on unitary and also on non-unitary infinite-dimensional half-bounded representations of the (2+1)D Lorentz algebra is revealed. Those associated with non-unitary representations interpolate between bosons and fermions. The extended formulation of the theory includes the previously known Jackiw-Nair (JN) and Majorana-Dirac (MD) descriptions of anyons as particular cases, and allows us to compose bosons and fermions from entangled anyons. The theory admits a simple supersymmetric generalization, in which the JN and MD systems are unified in N=1 and N=2 supermultiplets. Two different non-relativistic limits of the theory are investigated. The usual one generalizes Levy-Leblond's spin 1/2 theory to arbitrary spin, as well as to anyons. The second, "Jackiw-Nair" limit (that corresponds to Inonu-Wigner contraction with both anyon spin and light velocity going to infinity), is generalized to boson/fermion fields and interpolating anyons. The resulting exotic Galilei symmetry is studied in both the non-supersymmetric and the supersymmetric cases.

Magnetization plateaux, Haldane-like gap, string order and hidden symmetry in a spin-1/2 tetrameric Heisenberg antiferromagnetic chain

description: The ground-state properties of a spin $S=1/2$ tetrameric Heisenberg antiferromagnetic chain with alternating couplings AF$_{1}$-AF$_{2}$-AF$_{1}$% -F (AF and F denote antiferromagnetic and ferromagnetic couplings, respectively) are studied by means of the density matrix renormalization group method. Two plateaux of magnetization $m$ are found at $m=0$ and 1/4% . It is shown that in such a spin-1/2 AF system, there is a gap from the singlet ground state to the triplet excited states in the absence of a magnetic field. The spin-spin correlation function decays exponentially, and the gapped states have a nonvanishing string order, which measures a hidden symmetry in the system. By a dual transformation, the string order is transformed into a ferromagnetic order and the hidden symmetry is unveiled to be a $Z_{2}\times Z_{2}$ discrete symmetry, which is fully broken in the gapped states. This half-integer spin Heisenberg AF chain is in a Haldane-like phase, suggesting that the present findings extend the substance of Haldane's scenario. A valence-bond-solid state picture is also proposed for the gapped states.

The use of Delphi technique in conjunction with activity analysis to obtain congruency of objectives and activities within an academic medical department
Creators: name: Loughlin, Keith Gilbert
Publisher: name: University of British Columbia
Year: 2010

description: This study was undertaken to answer the following question. Can the Delphi technique be used in conjunction with activity analysis to obtain consensus and clarity of objectives and activities of full-time faculty members within an academic medical department? The results of this study indicate that the Delphi technique is a useful method for not only obtaining consensus of objectives, but also for elucidating areas where there is no apparent consensus. The results also indicated which activities contributed to the objectives of the department, and also the areas in which there was a divergence of objectives from the actual activities being carried out. The conclusions of this study are that the Delphi technique used in conjunction with activity analysis is an excellent methodology for identifying the objectives and activities which are performed within an academic medical department. Furthermore, the results and findings can be used as baseline data in setting departmental policies, as well as identifying areas in which structural change within the department is necessary in order that activities in the department may be more congruent with department objectives. Finally this methodology would be highly appropriate for undertaking studies of a similar nature in other academic medical department settings.

Equations, chromopermittivity and instabilities of the quark-gluon medium

description: The quark-gluon medium described by QCD equations is considered at high energies. Within the assumptions of the linear response theory the chromopermittivity of the medium is introduced and it is argued that it exceeds 1 at TeV energies. The dispersion equations show that the proper modes of the medium reveal instability and the parton currents traversing it induce the emission of Cherenkov gluons. Their distributions at LHC can differ from those typical for lower energies of RHIC because they are determined by the high energy dependence of the chromopermittivity while the latter ones arise due to collective resonance excitations. The distinction between Cherenkov gluons and Mach waves is discussed.

New form of kernel in equation for Nakanishi function

description: The Bethe-Salpeter amplitude $Φ(k,p)$ is expressed, by means of the Nakanishi integral representation, via a smooth function $g(γ,z)$. This function satisfies a canonical equation $g=Ng$. However, calculations of the kernel $N$ in this equation, presented previously, were restricted to one-boson exchange and, depending on method, dealt with complex multivalued functions. Although these difficulties are surmountable, but in practice, they complicate finding the unambiguous result. In the present work, an unambiguous expression for the kernel $N$ in terms of real functions is derived. For the one-boson scalar exchange, the explicit formula for $N$ is found. With this equation and kernel, the binding energies, calculated previously, are reproduced. Their finding, as well as calculation of the Bethe-Salpeter amplitude in the Minkowski space, become not more difficult than in the Euclidean one. The method can be generalized to any kernel given by irreducible Feynman graph. This generalization is illustrated by example of the cross-ladder kernel.

description: The observed abundance diversities among the CEMP stars can shed light on the formation and evolution of elements in the early Galaxy. In this work, we present results obtained from a detailed abundance analysis of a sample of seven extrinsic carbon stars. The analysis is based on high-resolution spectra obtained with HCT/HESP (R$\sim$60,000) and SUBARU/HDS (R$\sim$50,000). We present, for the first time, the elemental abundance results for the objects BD$-$19 132, BD$-$19 290, HE~1304$-$2111, HE~1354$-$2257, and BD+19 3109. Abundances of a few elements are available in literature for HE~1157$-$0518 and HD~202851, we present an update on the abundances of these elements along with new abundance estimates for several other elements. Our analysis confirms the object HD~202851 to be a CH star. While BD$-$19 132, HE~1354$-$2257, and BD+19 3109 are found to be CEMP-s stars, the objects BD$-$19 290, HE~1157$-$0518, and HE~1304$-$2111 are found to belong to CEMP-r/s group. The observed abundance patterns of the three CEMP-r/s stars are well reproduced with the i-process model predictions. While the objects BD+19 3109 and HD~202851 are confirmed binaries, the binary status of the remaining objects are not known. Analysis based on different elemental abundance ratios confirms low-mass former AGB companions for all the objects. Kinematic analysis shows that BD$-$19 290, HE~1157$-$0518, HE~1354$-$2257, and BD+19 3109 belong to the Galactic halo, whereas BD$-$19 132, HE~1304$-$2111, and HD~202851 are members of Galactic thin disk.

description: The ropelength of a knot is the minimum contour length of a tube of unit radius that traces out the knot in three dimensional space without self-overlap, colloquially the minimum amount of rope needed to tie a given knot. Theoretical upper and lower bounds have been established for the asymptotic relationship between crossing number and ropelength and stronger bounds have been conjectured, but numerical bounds have only been calculated exhaustively for knots and links with up to 11 crossings, which are not sufficiently complex to test these conjectures. Existing ropelength measurements also have not established the complexity required to reach asymptotic scaling with crossing number. Here, we investigate the ropelength of knots and links beyond the range of tested crossing numbers, past both the 11-crossing limit as well as the 16-crossing limit of the standard knot catalog. We investigate torus knots up to 1023 crossings, establishing a stronger upper bound for T(p,2) knots and links and demonstrating power-law scaling in T(p,p+1) below the proven limit. We investigate satellite knots up to 42 crossings to determine the effect of a systematic crossing-increasing operation on ropelength, finding that a satellite knot typically has thrice the ropelength of its companion. We find that ropelength is well described by a model of repeated Hopf links in which each component adopts a minimal convex hull around the cross-section of the others, and derive formulae that heuristically predict the crossing-ropelength relationship of knots and links without free parameters.

Study of materials and technology of ancient floor mosaics' substrate

description: Ancient pavements are composed of a variety of preparatory or foundation layers constituting the substrate, and of a layer of tesserae, pebbles or marble slabs forming the surface of the floor. In other cases, the surface consists of a mortar layer beaten and polished. The term mosaic is associated with the presence of tesserae or pebbles, while the more general term pavement is used in all the cases. As past and modern excavations of ancient pavements demonstrated, all pavements do not necessarily display the stratigraphy of the substrate described in the ancient literary sources. In fact, the number and thickness of the preparatory layers, as well as the nature and the properties of their constituent materials, are often varying in pavements which are placed either in different sites or in different buildings within a same site or even in a same building. For such a reason, an investigation that takes account of the whole structure of the pavement is important when studying the archaeological context of the site where it is placed, when designing materials to be used for its maintenance and restoration, when documenting it and when presenting it to public. Five case studies represented by archaeological sites containing floor mosaics and other kind of pavements, dated to the Hellenistic and the Roman period, have been investigated by means of in situ and laboratory analyses. The results indicated that the characteristics of the studied pavements, namely the number and the thickness of the preparatory layers, and the properties of the mortars constituting them, vary according to the ancient use of the room where the pavements are placed and to the type of surface upon which they were built. The study contributed to the understanding of the function and the technology of the pavementsâ substrate and to the characterization of its constituent materials. Furthermore, the research underlined the importance of the investigation of the whole structure of the pavement, included the foundation surface, in the interpretation of the archaeological context where it is located. A series of practical applications of the results of the research, in the designing of repair mortars for pavements, in the documentation of ancient pavements in the conservation practice, and in the presentation to public in situ and in museums of ancient pavements, have been suggested.

Study of the building and decorative materials and techniques used in Hungarian Roman sites
Creators: name: Ruggeri, Anna <1976>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2009
Subjects: CHIM/12 Chimica dell'ambiente e dei beni culturali

description: The aims of this research were:
- To identify the characteristics, properties and provenance of the building and
decorative material found in three Hungarian Roman sites: Nagyharsány,
Nemesvámos-Balácapuszta and Aquincum
- To provide a database of information on the different sites
- To have an overview of main conservation strategies applied in Hungary.
Geological studies, macroscopical and microscopical observations, XRD investigations,
physical and chemical analyses allowed us to define the characteristics and properties of the
different kinds of collected materials.
Building stones sampled from Nagyharsány site showed two different kinds of massive
limestone belonging to the areas surrounding the villa.
Also Building stones sampled from Nemesvámos-Balácapuszta Roman villa proved to be
compatible with limestone belonging to local sources.
Mural painting fragments show that all samples are units composed of multilayered
structures.
Mosaic tesserae can be classified as following:
-Pale yellow , blackish and pink tesserae are comparable with local limestone;
-White tessera, composed of marble, was probably imported from distant regions of the
Empire, as the usual practice of Romans.
Mortars present different characteristics according to the age, the site and the functions:
-Building mortars are generally lime based, white or pale yellow in colour, present a high
percentage of aggregates represented by fine sand;
-Supporting mortars from both mosaics and mural paintings are reddish or pinkish in colour,
due to the presence of high percentage of brick dust and tiles fragments, and present a higher
content of MgO.
Although the condition of the sites, there is an insignificant content of soluble salts.
Database
The whole study has allowed us to provide work sheets for each samples, including all
characteristics and properties.
Furthermore, all sites included in the frame of the research have been described and illustrated
on the base of their floor plans, material and construction methodologies.
It can be concluded that:
1. In Nagyharsány Archaeological site, it is possible to define a sequence of different
construction phases on the base of the study of building material and mortars. The
results are comparable with the chronology of the site provided by the archaeologists
2. The material used for construction was of local origin while the more precious ones,
used for decorative elements, were probably imported from long distance
3. Construction techniques in Hungary mainly refer to the usual Roman knowledge and
practice (Vitruvius); few differences have been found
4. The database will represent an archive for Archaeologists, Historians and
Conservators dealing with Roman period in Hungary.

description: We derive expressions for shock formation based on the local curvature of the flow characteristics during dynamic compression. Given a specific ramp adiabat, calculated for instance from the equation of state for a substance, the ideal nonlinear shape for an applied ramp loading history can be determined. We discuss the region affected by lateral release, which can be presented in compact form for the ideal loading history. Example calculations are given for representative metals and plastic ablators. Continuum dynamics (hydrocode) simulations were in good agreement with the algebraic forms. Example applications are presented for several classes of laser-loading experiment, identifying conditions where shocks are desired but not formed, and where long duration ramps are desired.

TeV scale Dark Matter and electroweak radiative corrections
Creators: name: Ciafaloni, Paolo

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Recent anomalies in cosmic rays data, namely from the PAMELA collaboration, can be interpreted in terms of TeV scale decaying/annihilating Dark Matter. We analyze the impact of radiative corrections coming from the electroweak sector of the Standard Model on the spectrum of the final products at the interaction point. As an example, we consider virtual one loop corrections and real gauge bosons emission in the case of a very heavy vector boson annihilating into fermions. We show that the effect of electroweak corrections is relevant, but not as big as sometimes claimed in the literature. At such high scales, one loop electroweak effects are so big that eventually higher orders/resummations have to be considered: we advocate for the inclusion of these effects in parton shower Montecarlos aiming at the description of TeV scale physics.

description: Convergence of time-sensitive machine control networks as part of the operational technology (OT) with the ubiquitous information technology (IT) networks is an essential requirement for the ongoing digitalization of production. In this paper, we review the fundamental differences between both technologies, the challenges to be solved, existing and upcoming solutions like TSN and their limitations. Furthermore, we introduce an Ethernet extension for a backbone network at factory scale and line rates of 10 - 100Gbit/s. The backbone is intended to carry massive amounts of IT traffic together with the traffic of multiple independent OT networks at the precision of leading-edge field bus technologies in the sub-microsecond range. The backbone remains transparent and does not require changes to the attached OT sub-networks. We prove our claims by prototype measurements, interoperability tests and field trials.
Dark matter admixed neutron star as a possible compact component in the GW190814 merger event

description: We put constraints on the secondary component of GW190814 by analyzing the observational data of the event. The relativistic mean-field models are used to calculate the mass-radius profile and tidal deformability of the compact object, considering it as a massive neutron star with the presence of dark matter particles inside it. With the increase of dark matter percentage, the maximum mass, radius, and tidal deformability of the neutron star decreases. We observe that the predicted properties are well consistent with GW190814 observational data, suggesting the possibility of a dark matter admixed neutron star if the underlying nuclear equation of state is sufficiently stiff.

Entrepreneurial opportunities, capability development and the performance of new firms
Creators: name: Giuliani, Antonio <1981>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2010
Subjects: SECS-P/08 Economia e gestione delle imprese

description: This study aims at providing a theoretical framework encompassing the two approaches towards entrepreneurial opportunity (opportunity discovery and opportunity creation) by outlining a trajectory from firm creation to capability development, to firm performance in the short term (firm survival) and the medium/long term (growth rate). A set of empirically testable hypotheses is proposed and tested by performing qualitative analyses on interviews on a small sample of entrepreneurs and event history analysis on a large sample of firms founded in the United States in 2004.

description: Radio propagation modeling and prediction is fundamental for modern cellular network planning and optimization. Conventional radio propagation models fall into two categories. Empirical models, based on coarse statistics, are simple and computationally efficient, but are inaccurate due to oversimplification. Deterministic models, such as ray tracing based on physical laws of wave propagation, are more accurate and site specific. But they have higher computational complexity and are inflexible to utilize site information other than traditional global information system (GIS) maps. In this article we present a novel method to model radio propagation using deep convolutional neural networks and report significantly improved performance compared to conventional models. We also lay down the framework for data-driven modeling of radio propagation and enable future research to utilize rich and unconventional information of the site, e.g. satellite photos, to provide more accurate and flexible models.
Memorie traumatiche, fotografie e intermedialità nella narrativa contemporanea di lingua inglese
Traumatic Memories, Photography and Intermediality in Anglophone Contemporary Narrative

description: La fotografia viene utilizzata intermedialmente per la narrazione di contromemorie e memorie traumatiche ricorrendo a numerose modalità e strategie di inserzione e impiego diverse. Se l’intermedialità da un lato non è riconducibile ad una serie di pratiche convenzionali, ma dipende dal contesto narrativo, dall’altro essa detiene un’organicità che la allinea funzionalmente ai processi e alle indagini sulla rappresentabilità del trauma. Inoltre, per la versatilità della sua natura poliedrica, la pratica narrativa intermediale (nelle sue configurazioni più diverse) assume una valenza epistemologica e metodologica nei confronti degli studi sull’esternazione e rielaborazione del trauma. Questo studio si prefigge di mettere a confronto testi teorici e testi narrativi per metterne in rilievo il reciproco apporto.
description: Photography is used intermedially, recurring to different insertion modalities and strategies, to narrate countermemories and traumatic memories. Although intermediality is not ascribable to a series of convential practices, depending each of them on the narrative context, however it detains an organicity that guarantees the possibility to align it functionally to the processes and studies on the representability of trauma. 
Morever, because of the versatility of its poliedric nature, the narrative use of intermedial photographies (in their different declensions) retains an epistemological and methodological value for the studies on the externalization and processing of trauma. The aim of this study is to confront theoretical and narrative texts to analyze how they influence each other.
