description: Stellar mass black holes (BHs) are expected to segregate and form a steep density cusp around supermassive black holes (SMBHs) in galactic nuclei. We follow the evolution of a multi-mass system of BHs and stars by numerically integrating the Fokker-Planck energy diffusion equations for a variety of BH mass distributions. We find that the BHs "self-segregate'', and that the rarest, most massive BHs dominate the scattering rate closest to the SMBH (< 0.1 pc). BH--BH binaries form out of gravitational wave emission during BH encounters. We find that the expected rate of BH coalescence events detectable by Advanced LIGO is ~1 - 100/yr, depending on the initial mass function of stars in galactic nuclei and the mass of the most massive BHs. We find that the actual merger rate is likely ~10 times larger than this due to the intrinsic scatter of stellar densities in many different galaxies. The BH binaries that form this way in galactic nuclei have significant eccentricities as they enter the LIGO band (90% with e > 0.9), and are therefore distinguishable from other binaries, which circularise before becoming detectable. We also show that eccentric mergers can be detected to larger distances and greater BH masses than circular mergers, up to ~ 700 solar masses. Future ground-based gravitational wave observatories will be able to constrain both the mass function of BHs and stars in galactic nuclei.

description: A topologically protected ring-resonator formed in valley photonic crystals is proposed and fabricated on a silicon slab. The unidirectional transmission and robustness against structure defects of its resonant modes are illustrated. Coupled with topological waveguides, the topological ring is functioned as notch and channel-drop filters.

Frustration Effects in Antiferromagnetic FCC Heisenberg Films

description: We study the effects of frustration in an antiferromagnetic film of FCC lattice with Heisenberg spin model including an Ising-like anisotropy. Monte Carlo (MC) simulations have been used to study thermodynamic properties of the film. We show that the presence of the surface reduces the ground state (GS) degeneracy found in the bulk. The GS is shown to depend on the surface in-plane interaction $J_s$ with a critical value at which ordering of type I coexists with ordering of type II. Near this value a reentrant phase is found. Various physical quantities such as layer magnetizations and layer susceptibilities are shown and discussed. The nature of the phase transition is also studied by histogram technique. We have also used the Green's function (GF) method for the quantum counterpart model. The results at low-$T$ show interesting effects of quantum fluctuations. Results obtained by the GF method at high $T$ are compared to those of MC simulations. A good agreement is observed.

description: As news organizations embrace transparency practices on their websites to distinguish themselves from those spreading misinformation, HCI designers have the opportunity to help them effectively utilize the ideals of transparency to build trust. How can we utilize transparency to promote trust in news? We examine this question through a qualitative lens by interviewing journalists and news consumers -- the two stakeholders in a news system. We designed a scenario to demonstrate transparency features using two fundamental news attributes that convey the trustworthiness of a news article: source and message. In the interviews, our news consumers expressed the idea that news transparency could be best shown by providing indicators of objectivity in two areas (news selection and framing) and by providing indicators of evidence in four areas (presence of source materials, anonymous sourcing, verification, and corrections upon erroneous reporting). While our journalists agreed with news consumers' suggestions of using evidence indicators, they also suggested additional transparency indicators in areas such as the news reporting process and personal/organizational conflicts of interest. Prompted by our scenario, participants offered new design considerations for building trustworthy news platforms, such as designing for easy comprehension, presenting appropriate details in news articles (e.g., showing the number and nature of corrections made to an article), and comparing attributes across news organizations to highlight diverging practices. Comparing the responses from our two stakeholder groups reveals conflicting suggestions with trade-offs between them. Our study has implications for HCI designers in building trustworthy news systems.

Cluster Formation in Contracting Molecular Clouds

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We explore, through a simplified, semi-analytic model, the formation of dense clusters containing massive stars. The parent cloud spawning the cluster is represented as an isothermal sphere. This sphere is in near force balance between self-gravity and turbulent pressure. Self-gravity, mediated by turbulent dissipation, drives slow contraction of the cloud, eventually leading to a sharp central spike in density and the onset of dynamical instability. We suggest that, in a real cloud, this transition marks the late and rapid production of massive stars. We also offer an empirical prescription, akin to the Schmidt law, for low-mass star formation in our contracting cloud. Applying this prescription to the Orion Nebula Cluster, we are able to reproduce the accelerating star formation previously inferred from the distribution of member stars in the HR diagram. The cloud turns about 10 percent of its mass into low-mass stars before becoming dynamically unstable. Over a cloud free-fall time, this figure drops to 1 percent, consistent with the overall star formation efficiency of molecular clouds in the Galaxy.

Effects of simulation dimensionality on laser-driven electron acceleration and photon emission in hollow micro-channel targets

description: Using two-dimensional (2D) and three-dimensional (3D) kinetic simulations, we examine the impact of simulation dimensionality on the laser-driven electron acceleration and the emission of collimated $γ$-ray beams from hollow micro-channel targets. We demonstrate that the dimensionality of the simulations considerably influences the results of electron acceleration and photon generation owing to the variation of laser phase velocity in different geometries. In a 3D simulation with a cylindrical geometry, the acceleration process of electrons terminates early due to the higher phase velocity of the propagating laser fields; in contrast, 2D simulations with planar geometry tend to have prolonged electron acceleration and thus produce much more energetic electrons. The photon beam generated in the 3D setup is found to be more diverged accompanied with a lower conversion efficiency. Our work concludes that the 2D simulation can qualitatively reproduce the features in 3D simulation, but for quantitative evaluations and reliable predictions to facilitate experiment designs, 3D modelling is strongly recommended.

description: The nature of the several microlensing events observed by the MACHO team towards the LMC still remains controversial. Low-mass substellar objects and stars with masses larger than ~1 M_{sun} have been ruled out as major components of a MACHO galactic halo, while stars of half solar masses are the most probable candidates. In this paper we assess jointly the relative contributions of both red dwarfs and white dwarfs to the mass budget of the galactic halo. In doing so we use a Monte Carlo simulator which incorporates up-to-date evolutionary sequences of both red dwarfs and white dwarfs as well as detailed descriptions of our Galaxy and of the LMC. We explore the complete mass range between 0.08 and 1 M_{sun} as possible microlensing candidates and we compare the synthetic populations obtained with our simulator with the results obtained by the MACHO and EROS experiments. Our results indicate that, despite that the contribution of the red dwarf population increases by a factor of 2 the value of the optical depth obtained when taking into account the white dwarf population alone, it is still insufficient to explain the number of events claimed by the MACHO team. Finally, we find that the contribution to the halo dark matter of the whole population under study is smaller than 10% at the 95% conficence level.

Analysis and Application of Bifurcations in Systems with Impacts and Chattering.
Creators: name: Alzate, Ricardo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: In this Thesis we present the implementation and characterization of a practical impact oscillator: the cam-follower system. Complex dynamics experienced by the system after variation of the rotational speed of the cam taken as parameter, are analyzed through experimental, numerical and analytical tools. The most representative feature captured experimentally and reproduced after accurate simulation of the model, is the coexistence between a single-impacting periodic orbit and a multi-impacting trajectory with chattering, all of this occurring over a representative range of parameter values. Exhaustive numerical and analytical investigation including: Monte Carlo simulations, numerical continuation, calculation of basins of attraction and local analysis of perturbations, allowed to demonstrate that the interruption of complete chattering motion creates a sudden transition to chaos in the multi-impacting orbit characterized by a scaled and translated sequence of grazing bifurcations. An expression for the map local to the interruption of complete chattering is derived after performing expansion in series of the solutions; i.e. by analysis of variational equations, with further numerical validation. Additional work includes the extension of the local results for an accurate derivation of the equivalent Poincaré map describing the periodic chattering orbit.

The Collision Between The Milky Way And Andromeda
Creators: name: Cox, T. J.

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use a N--body/hydrodynamic simulation to forecast the future encounter between the Milky Way and the Andromeda galaxies, given current observational constraints on their relative distance, relative velocity, and masses. Allowing for a comparable amount of diffuse mass to fill the volume of the Local Group, we find that the two galaxies are likely to collide in a few billion years - within the Sun's lifetime. During the the interaction, there is a chance that the Sun will be pulled away from its present orbital radius and reside in an extended tidal tail. The likelihood for this outcome increases as the merger progresses, and there is a remote possibility that our Sun will be more tightly bound to Andromeda than to the Milky Way before the final merger. Eventually, after the merger has completed, the Sun is most likely to be scattered to the outer halo and reside at much larger radii (>30 kpc). The density profiles of the stars, gas and dark matter in the merger product resemble those of elliptical galaxies. Our Local Group model therefore provides a prototype progenitor of late--forming elliptical galaxies.

description: Struggling to curb misinformation, social media platforms are experimenting with design interventions to enhance consumption of credible news on their platforms. Some of these interventions, such as the use of warning messages, are examples of nudges -- a choice-preserving technique to steer behavior. Despite their application, we do not know whether nudges could steer people into making conscious news credibility judgments online and if they do, under what constraints. To answer, we combine nudge techniques with heuristic based information processing to design NudgeCred -- a browser extension for Twitter. NudgeCred directs users' attention to two design cues: authority of a source and other users' collective opinion on a report by activating three design nudges -- Reliable, Questionable, and Unreliable, each denoting particular levels of credibility for news tweets. In a controlled experiment, we found that NudgeCred significantly helped users (n=430) distinguish news tweets' credibility, unrestricted by three behavioral confounds -- political ideology, political cynicism, and media skepticism. A five-day field deployment with twelve participants revealed that NudgeCred improved their recognition of news items and attention towards all of our nudges, particularly towards Questionable. Among other considerations, participants proposed that designers should incorporate heuristics that users' would trust. Our work informs nudge-based system design approaches for online media.

description: We study the surface tension and the phenomenon of phase coexistence for the Ising model on $\mathbbm{Z}^d$ ($d \geqslant 2$) with ferromagnetic but random couplings. We prove the convergence in probability (with respect to random couplings) of surface tension and analyze its large deviations : upper deviations occur at volume order while lower deviations occur at surface order. We study the asymptotics of surface tension at low temperatures and relate the quenched value $τ^q$ of surface tension to maximal flows (first passage times if $d = 2$). For a broad class of distributions of the couplings we show that the inequality $τ^a \leqslant τ^q$ -- where $τ^a$ is the surface tension under the averaged Gibbs measure -- is strict at low temperatures. We also describe the phenomenon of phase coexistence in the dilute Ising model and discuss some of the consequences of the media randomness. All of our results hold as well for the dilute Potts and random cluster models.
“MicroRNA Expression Profiling in human
Subcutaneous Adipose Tissue”
Creators: name: Castanò, Ilenia
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: MicroRNA are believed to be generally involved in more quantitative regulation of
mammalian trait: therefore, mammalian conditions that have a strong genetic
component and involve quantitative differences between the physiological and
pathological conditions are strong candidates to be influenced by miRNA
disregulations. The pool of this study is thus to investigate the possible role for miRNA
imbalance in adipose tissue in the development of obesity.
To date, microRNAs have been identified and evaluated in human preadipocytes (miR-
143) and mouse hepatocytes (miR-122). There is no study dealing with microRNA in
subcutaneous adipose tissue (SAT) of obese patients.
For this reason, we have performed an high-throughput screening by microarray
analysis on 1,458 microRNAs in SAT from 20 morbidly obese patients (10 men and 10
female) versus pools of RNA from non obese subjects (3 men and 5 female).
We were able to identify miRNAs differentially expressed comparing SAT from obese
patients with respect to SAT from non-obese patients.
The miR-519d was significantly higher in obese subjects than in the non obese pools.
Using bioinformatic and functional analyses, we have demonstrated that the peroxisome
proliferator activated receptor A (PPARA) gene resulted be a target of miR-519d.
PPARA regulates the genes involved in fatty acid, glucose metabolism and
inflammation (Cho et al., 2008). Therefore, it is conceivable that loss of PPARA could
cause metabolic imbalance, thereby resulting in adipocyte hypertrophy in SAT from
morbidly obese subjects.
This project set the goal to be a part of the effort in understanding the biology and the
role of this miR-519d during biogenesis of obesity.
Numerical experiments using an electrostatic, relativistic plasma simulation code
Creators: name: Parachoniak, Ronald D.
Publisher: name: University of British Columbia
Year: 2010

description: A 1-1/2 dimensional electrostatic, relativistic, plasma simulation model was constructed, implemented on the UBC FPS array processor, and tested by solving three problems in plasma physics. The model will handle a variety of different initial conditions including cold plasmas, cold beams, and drifting maxwellians. Relativistic particle velocities are properly modelled and up to two species of particles may be specified. The numerical experiments run with the model included cold plasma oscillations, cold and warm two-stream instabilities, and Landau damping. Results of the simulations were compared to theory and excellent agreement was obtained in all the cases studied. The model may now be used with confidence to research various (relativistic) electrostatic problems. It could also be modified to make it fully electromagnetic, in which case it would be useful for simulating many additional phenomena, including laser-plasma interactions.
Momentum transfer to small particles by aloof electron beams

Year: 2007
Subjects: subject: Other Condensed Matter (cond-mat.other)

description: The force exerted on nanoparticles and atomic clusters by fast passing electrons like those employed in transmission electron microscopes are calculated and integrated over time to yield the momentum transferred from the electrons to the particles. Numerical results are offered for metallic and dielectric particles of different sizes (0-500 nm in diameter) as well as for carbon nanoclusters. Results for both linear and angular momentum transfers are presented. For the electron beam currents commonly employed in electron microscopes, the time-averaged forces are shown to be comparable in magnitude to laser-induced forces in optical tweezers. This opens up the possibility to study optically-trapped particles inside transmission electron microscopes.

sulla sola matrice che è stata caricata a tale scopo con polveri di materiale duro e metallico, per continuare con sperimentazioni eseguite su laminati nei quali le lamine esterne a contatto con l’ambiente fossero formate adoperando una matrice allo stesso modo caricata.
Tutto ciò alla luce del fatto che un materiale composito con radiente funzionale delle proprietà determinato dalla distribuzione della carica nella matrice, evita i problemi inerenti le tecnologie di rivestimento e rende la  esistenza ad usura una proprietà intrinseca della lamina.

Towards informed diversity in IP networks: techniques, issues, and solutions
Creators: name: Botta, Alessio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: The current Internet scenario is very different from that envisioned in the original plan. The original protocols of the Internet were designed to allow simple communications between a few hundreds of academic and government users, which were assumed to be fixed and trusted. Today, a wide range of new access technologies have been introduced, which make user mobility and ubiquitous access easier and widely adopted. On the other hand, new applications and services are spreading, some of which are becoming almost necessary for our life. This new scenario poses several challenges to the Internet infrastructure, and different approaches have been proposed in literature towards the Future Internet. Adopting an evolutionary approach, in this thesis we provide contributions in the area of space and time diversity at IP layer, aiming to overcome limitations of current Internet infrastructure. In particular, we propose new techniques implementing what we call informed diversity: space and time diversity using information about the status of the network to make informed decisions about the operating parameters. We adopt a methodology composed of theoretical, simulations, and experimental analysis, and we provide contributions in terms of methodologies and techniques for network monitoring, and in terms of innovative techniques and tools for space and time diversity at IP layer. Obtained results show that informed space and time diversity achieve better performance than traditional techniques.

Nello specifico il lavoro di tesi è così articolato.
Il primo capitolo ha lo scopo di introdurre e presentare nel dettaglio il Data Fusion in tutte le sue fasi metodologiche, partendo dalla definizione del fusion e specificando i modelli e i metodi con cui vengono effettuate le fusioni.
Il secondo capitolo definisce, approfondisce e analizza sinteticamente la tecnica dell’ACPR. Nello stesso capitolo espone nel dettaglio l’utilizzo dell’ACPR per la soluzione del problema della similarità tra soggetti, e i vari passaggi che consentono l’utilizzo di una tecnica non simmetrica nel file grafting.
Il terzo capitolo pone l’attenzione sulle condizioni che consentono di effettuare il file grafting. In particolare, con la proposta di un test per la verifica della non significatività delle differenze tra le strutture delle variabili in comune alle due indagini.
Il quarto capitolo propone un nuovo algoritmo per il file grafting, provando a dare una nuova soluzione al problema della fusione dei dati. Il modello proposto denominato Grafting non simmetrico, è concepito con lo scopo di evidenziare similitudini tra i soggetti delle due indagini, alla luce della relazione, verificata esistente, tra i due gruppi di variabili che compongono l’indagine di riferimento.

Fine Gradings of Low-Rank Complex Lie Algebras and of Their Real Forms

description: In this review paper, we treat the topic of fine gradings of Lie algebras. This concept is important not only for investigating the structural properties of the algebras, but, on top of that, the fine gradings are often used as the starting point for studying graded contractions or deformations of the algebras. One basic question tackled in the work is the relation between the terms 'grading' and 'group grading'. Although these terms have originally been claimed to coincide for simple Lie algebras, it was revealed later that the proof of this assertion was incorrect. Therefore, the crucial statements about one-to-one correspondence between fine gradings and MAD-groups had to be revised and re-formulated for fine group gradings instead. However, there is still a hypothesis that the terms 'grading' and 'group grading' coincide for simple complex Lie algebras. We use the MAD-groups as the main tool for finding fine group gradings of the complex Lie algebras $A_3 \cong D_3$, $B_2 \cong C_2$, and $D_2$. Besides, we develop also other methods for finding the fine (group) gradings. They are useful especially for the real forms of the complex algebras, on which they deliver richer results than the MAD-groups. Systematic use is made of the faithful representations of the three Lie algebras by $4\times 4$ matrices: $A_3 = sl(4,\mathbb C)$, $C_2 = sp(4,\mathbb C)$, $D_2 = o(4,\mathbb C)$. The inclusions $sl(4,\mathbb C)\supset sp(4,\mathbb C)$ and $sl(4,\mathbb C) \supset o(4,\mathbb C)$ are important in our presentation, since they allow to employ one of the methods which considerably simplifies the calculations when finding the fine group gradings of the subalgebras $sp(4,\mathbb C)$ and $o(4,\mathbb C)$.

description: В связи с отсутствием в научной литературе классификации реверсивных логистических систем проведение исследований на основе общей теоретической базы невозможно, поэтому либо исследуют частные реверсивные логистические системы предприятий, либо основывают исследования на «модельной» теоретической системе, не соотносящейся с уже функционирующими логистическими системами. Такой разрыв в научном понимании реверсивной логистики обусловил цель данного исследования – разработать классификацию видов реверсивных логистических систем. В статье рассмотрены причины возникновения интереса организаций к работе с реверсивной логистикой в рамках их собственной системы прямой логистики как фактора устойчивой конкурентоспособности и развития, создана трехуровневая классификация видов и типов систем реверсивной логистики с учетом требований законодательства, форм и видов предприятий, сфер функционирования, рыночных ситуаций и экономических факторов.
description: Due to the absence in the scientific literature of the classification of reverse logistics systems, it is impossible to research the basis of a common theoretical base. Therefore, either private reversible logistic systems of enterprises are investigated, or the studies are based on a “model” theoretical system that does not correspond to already functioning logistic systems. Such a gap in the scientific understanding of reverse logistics led to the purpose of this study, namely, to develop a classification of types of reverse logistics systems. The article discusses the reasons for the emergence of interest of organizations to work with reverse logistics within the framework of their own direct logistics system as a factor of sustainable competitiveness and development. Based on various requirements, forms, and types of organizations, areas of operation, market situations, and economic factors, a three-level classification of reverse logistics systems has been developed.
A 21 cm. line study of the Taurus Molecular Complex
Creators: name: Klatt, Calvin Glenn
Publisher: name: University of British Columbia
Year: 2010

description: The large scale distribution of 21 cm self absorption in the Taurus Molecular Complex has been determined from observations made by us at Arecibo Observatory in October 1985. Results have been compared with ¹³CO previously observed by Kleiner and Dickman at FCRAO. The principal conclusions drawn from a two-dimensional auto and cross-correlation analysis are: (1) The cold atomic hydrogen in the Taurus Complex has an extremely well defined condensation scale length of 14 pc, as was found for CO. (2) The 21 cm and CO column densities are essentially uncorrelated. Previous thinking would have predicted a high degree of correlation if the HI and CO were well mixed, or a high degree of anticorrelation if the atomic hydrogen was distributed in shells around the molecular gas.

Il profilo di espressione di SERT nel cuore, evidenziato dalla colorazione LacZ negli embrioni di topi SERTCre/+;R26R sin dagli stadi più precoci, e la caratterizzazione del fenotipo di topi SERT-KO ha fornito nuove evidenze sul ruolo di SERT nello sviluppo del cuore, nella funzionalità dell’organo e in patologie delle valvole cardiache associate ad alterazioni dei livelli di serotonina. Inoltre, il profilo di espressione di SERT durante lo sviluppo delle valvole cardiache e l’analisi dei meccanismi molecolari coinvolti nel processo di fibrosi cardiaca indotto dalla serotonina fornisce le basi per lo sviluppo di nuove terapie dirette alla cura e alla prevenzione di malattie cardiovascolari che interessano le valvole cardiache. Infine, il nostro studio ha fornito un ulteriore conferma sperimentale all’ipotizzata relazione causale tra alterazioni del gene SERT e l’insorgenza della SIDS.
L’analisi dell’espressione di SERT nel cervello di topi SERTCre/+;R26R ha permesso di identificare nuovi siti in cui il trasportatore è fortemente attivo durante le fasi precoci dello sviluppo embrionale, mettendo in evidenza i potenziali rischi correlati all’abuso di cocaina o di altre droghe o di farmaci SSRI che hanno SERT quale bersaglio durante la gravidanza.
Infine, lo studio dell’espressione di SERT nella tiroide di embrioni e topi adulti SERTCre/+;R26R ha consentito di stabilire che le cellule follicolari della ghiandola esprimono SERT sin dagli stadi più precoci dello sviluppo, mettendo in evidenza un ulteriore sito di vulnerabilità da considerare nel rischio dell’esposizione a droghe o farmaci SSRI nel periodo prenatale. In conclusione, i risultati del nostro studio possono contribuire all’avanzamento delle conoscenze sul ruolo della serotonina e di SERT nelle funzioni fisiologiche del cuore, cervello e tiroide dei mammiferi ed in numerose patologie correlate all’età, a fattori congeniti e all’uso di droghe e farmaci.

description: We present a search for a pentaquark decaying strongly to $Ξ^-π^-$ in $γN$ collisions at a center-of-mass energy up to 25 GeV/c^2. Finding no evidence for such a state in the mass range of 1480 MeV/c^2 to 2400 MeV/c^2, we set limits on the yield and on the cross section times branching ratio relative to $Ξ^*(1530)^0$.

Controlli sulla filiera avicola: trasporto, igiene della macellazione e decontaminazione delle carni trite di pollo mediante alte pressioni idrostatiche

description: L’allevamento avicolo intesivo, integrato a grandi complessi industriali deve essere inserito in un sistema di filiera dove i controlli di tutti gli anelli di congiunzione devono assicurare carni e/o prodotti preparati o trasformati ineccepibili da un punto di vista igienico-sanitario. Obiettivi della ricerca svolta nel corso del trienno del Dottorato di ricerca sono stati quindi:
1) Osservazioni sulle condizioni  di trasporto del pollame destinato alla macellazione;
2) Monitoraggio microbiologico delle condizioni di lavorazioni in un macello avicolo;
3) Raffronto tra metodo distruttivo e non per le analisi microbiologiche su carcasse avicole;
4) Inattivazione di Listeria innocua in Triptic Soy Broth e carni macinate di pollame mediante le Alte Pressioni Idrostatiche.
Il primo aspetto da considerare nella macellazione degli animali è il  trasporto dall’allevamento al macello. Tale fase deve essere monitorata,considerato che il carico,il viaggio e  lo scarico sono eventi stressanti,che,anche se con una certa variabilità di specie,possono accentuare da un lato problematiche già presenti in allevamento e dall’altro influenzare il livello di contaminazione delle carcasse nonché la qualità delle carni.
Un altro aspetto da considerare è la verifica  sistemica della qualità e del tipo di flora microbica presente sulla superficie delle carcasse alla fine della catena di macellazione per valutare concretamente la corretta applicazione delle buone pratiche di produzione o lavorazione, considerate la inevitabilità e la molteplicità delle fonti di inquinamento.
Le procedure tradizionali di ispezione dellle carni possono non essere sufficienti ad assicurare l’assenza di microrganismi potenzialmente patogeni per il consumatore.
Le analisi batteriologiche della superfice delle carcasse degli animali quindi sono diventate un’importante fonte di informazione nell’applicazione e nell’adempimento delle procedure di H.A.C.C.P durante le operazioni di macellazione e di lavorazione delle carni avicole.
Le Alte Pressioni Idrostatiche appartengono, alla categoria di quelle tecniche di conservazione degli alimenti che, pur eliminando dal prodotto forme microbiche potenzialmente pericolose per la salute umana e inibendo la proliferazione della microflora alterante, incidono relativamente poco sulle caratteristiche sensoriali e nutritive del prodotto.  Si è testato il comportamento di Listeria innocua inoculata in campioni di carne trita di pollame  sottoposti a trattamento ciclico con le Alte Pressioni Idrostatiche .
La baroresistenza del microrganismo a concetrazioni di 107 - 108 ufc/ml è stata testata con pressioni comprese tra 150 e 550 Mpa sia in continuo che in cicli.
L’incremento del numero dei cicli ha permesso la riduzione del livello di pressione ed ha portato alla totale inattivazione della Listeria innocua nei campioni di carne trita.

description: The recent debate on hypercomputation has arisen new questions both on the computational abilities of quantum systems and the Church-Turing Thesis role in Physics. We propose here the idea of "effective physical process" as the essentially physical notion of computation. By using the Bohm and Hiley active information concept we analyze the differences between the standard form (quantum gates) and the non-standard one (adiabatic and morphogenetic) of Quantum Computing, and we point out how its Super-Turing potentialities derive from an incomputable information source in accordance with Bell's constraints. On condition that we give up the formal concept of "universality", the possibility to realize quantum oracles is reachable. In this way computation is led back to the logic of physical world.

A Near-infrared Survey of UV-excited Molecular Hydrogen in Photodissociation Regions

description: We present a comparative study of the near-infrared (NIR) H$_2$ line emission from five regions near hot young stars: Sharpless 140, NGC 2023, IC 63, the Horsehead Nebula, and the Orion Bar. This emission originates in photodissociation or photon-dominated regions (PDRs), interfaces between photoionized and molecular gas near hot (O) stars or reflection nebulae illuminated by somewhat cooler (B) stars. In these environments, the dominant excitation mechanism for NIR emission lines originating from excited rotational-vibrational (rovibrational) levels of the ground electronic state is radiative or UV excitation (fluorescence), wherein absorption of far-UV photons pumps H$_2$ molecules into excited electronic states from which they decay into the upper levels of the NIR lines. Our sources span a range of UV radiation fields ($G_0 = 10^2$-$10^5$) and gas densities ($n_H = 10^4$-$10^6$ cm$^{-3}$), enabling examination of how these properties affect the emergent spectrum. We obtained high-resolution ($R \approx 45,000$) spectra spanning $1.45$-$2.45$~$μ$m on the 2.7m Harlan J. Smith Telescope at McDonald Observatory with the Immersion Grating INfrared Spectrometer (IGRINS), detecting up to over 170 transitions per source from excited vibrational states ($v = 1$-$14$). The populations of individual rovibrational levels derived from these data clearly confirm UV excitation. Among the five PDRs in our survey, the Orion Bar shows the greatest deviation of the populations and spectrum from pure UV excitation, while Sharpless 140 shows the least deviation. However, we find that all five PDRs exhibit at least some modification of the level populations relative to their values under pure UV excitation, a result we attribute to collisional effects.

description: Das eherne Vorhaben, die Einheit der Muslime voranzutreiben, das dürfte der KRM mit diesem Aktionismus angesichts der Kommissionspläne des Landes NRW beiseite gelegt haben. Vielleicht vor einem Jahr noch, als es nicht darum ging, die alleinige Entscheidungsmacht der KRM-Mitglieder im nordrhein-westfälischen Religionsunterricht zu verteidigen, hätte sich der KRM noch auf dieses richtige und wichtige Ziel einer gemeinsamen Vertretungs- und Kooperationsinstanz berufen können. Das Argument verliert jedoch seine Bedeutung, wenn es am Ende nur noch um die Wahrung der Besitzstände der „Großen“ geht – auf Kosten der berechtigten Interessen der kleineren muslimischen Gemeinschaften.

description: We use the Gutzwiller variational theory to investigate the electronic and the magnetic properties of fcc-Nickel. Our particular focus is on the effects of the spin-orbit coupling. Unlike standard relativistic band-structure theories, we reproduce the experimental magnetic moment direction and we explain the change of the Fermi-surface topology that occurs when the magnetic moment direction is rotated by an external magnetic field. The Fermi surface in our calculation deviates from early de-Haas--van-Alphen (dHvA) results. We attribute these discrepancies to an incorrect interpretation of the raw dHvA data.

Linking Short Gamma Ray Bursts and their Host Galaxies

description: The luminosities of short gamma ray burst host galaxies are anticorrelated with both the isotropic equivalent gamma ray energy and the gamma ray luminosity of the explosions. Observational selection effects only strengthen the significance of this correlation. The correlation may indicate that there are two physically distinct groups of SGRBs. If so, it requires that the more luminous class of explosions be associated with the younger class of progenitors. Alternatively, it could be due to a continuous distribution of burst and host properties. As one possible explanation, we find that the effect of binary neutron star masses on inspiral time and energy reservoir produces a correlation of the appropriate sign, but does not automatically reproduce the correlation slope or the full range of SGRB energy scales. Any future model of SGRB progenitors needs to reproduce this correlation.
