description: We present high angular resolution ($\sim$ 3$''$) and sensitive 1.3 mm continuum, cyanogen (CN) and vinyl cyanide (C$_2$H$_3$CN) line observations made with the Submillimeter Array (SMA) toward one of most highly obscured objects of the W51 IRS2 region, W51 North. We find that the CN line exhibits a pronounced inverse P-Cygni profile indicating that the molecular gas is infalling inwards this object with a mass accretion rate between 4 and 7 $\times$ 10$^{-2}$ M$_\odot$ yr$^{-1}$. The C$_2$H$_3$CN traces an east-west rotating molecular envelope that surrounds either a single obscured (proto)star with a kinematic mass of 40 M$_{\odot}$ or a small central cluster of B-type stars and that is associated with a compact high velocity bipolar outflow traced by H$_2$O masers and SiO molecular emission. We thus confirm that the W51 North region is part of the growing list of young massive star forming regions that have been associated with infalling motions and with large mass accretion rates ($\sim$ 10$^{-2}$ -- 10$^{-4}$), strengthening the evidence for massive stars forming with very high accretion rates sufficient to quench the formation of an UCHII region.

description: The measurements of the bulk properties of most isolated neutron stars (INSs) are challenging tasks. Tang et al. (2020) have developed a new method, based on the equation of state (EoS) of neutron star (NS) material constrained by the observational data, to infer the gravitational masses of a few INSs whose gravitational redshifts are available. However, in that work, the authors only considered the constraints on the EoS from nuclear experiments/theories and the gravitational wave data of GW170817; the possible phase transition has not been taken into account. In this work, we adopt three EoS models (including the one incorporates a first-order strong phase transition) that are constrained by the latest multimessenger NS data, including in particular the recent mass\textendash radius measurements of two NSs by Neutron Star Interior Composition Explorer, to update the estimation of the gravitational masses of RBS 1223, RX J0720.4-3125, and RX J1856.5-3754. In comparison to our previous approach, the new constraints are tighter, and the gravitational masses are larger by about $0.1M_\odot$. All the inferred gravitational masses are within the range of the NS masses measured in other ways. We have also calculated the radius, tidal-deformability, and moment of inertia of these sources. The inclusion of the first-order strong phase transition has little influence on modifying the results.

description: Oogenesis in the urochordate, Oikopleura dioica, occurs in a large coenocyst in which vitellogenesis precedes oocyte selection in order to adapt oocyte production to nutrient conditions. The animal has expanded Cyclin-Dependant Kinase 1 (CDK1) and Cyclin B paralog complements, with several expressed during oogenesis. Here, we addressed functional redundancy and specialization of CDK1 and cyclin B paralogs during oogenesis and early embryogenesis through spatiotemporal analyses and knockdown assays. CDK1a translocated from organizing centres (OCs) to selected meiotic nuclei at the beginning of the P4 phase of oogenesis, and its knockdown impaired vitellogenesis, nurse nuclear dumping, and entry of nurse nuclei into apoptosis. CDK1d-Cyclin Ba translocated from OCs to selected meiotic nuclei in P4, drove meiosis resumption and promoted nuclear envelope breakdown (NEBD). CDK1d-Cyclin Ba was also involved in histone H3S28 phosphorylation on centromeres and meiotic spindle assembly through regulating Aurora B localization to centromeres during prometaphase I. In other studied species, Cyclin B3 commonly promotes anaphase entry, but we found O. dioica Cyclin B3a to be non-essential for anaphase entry during oogenic meiosis. Instead, Cyclin B3a contributed to meiotic spindle assembly though its loss could be compensated by Cyclin Ba.

description: In this work, the simulation of optical photons is carried out in an antineutrino detector module consisting of a plastic scintillator connected to light guides and photomultipliers on both ends, which is considered to be used for remote reactor monitoring in the field of nuclear safety. Using Monte Carlo (MC) based GEANT4 simulation, numerous parameters influencing the light collection and thereby the energy resolution of the antineutrino detector module are studied: e.g., degrees of scintillator surface roughness, reflector type, and its ap- plying method onto scintillator and light guide surface, the reflectivity of the reflector, light guide geometries and diameter of the photocathode. The impact of each parameter is inves- tigated by looking at the detected spectrum, i.e. the number photoelectrons per depositing energy. In addition, the average light collection efficiency of the detector module and its spatial variation are calculated for each simulation setup. According to the simulation re- sults, it is found that photocathode size, light guide shape, reflectivity of reflecting material and wrapping method show a significant impact on the light collection efficiency while scin- tillator surface polishing level and the choose of reflector type show relatively less impact. This study demonstrates that these parameters are very important in the design of plastic scintillator included antineutrino detectors to improve the energy resolution efficiency.

description: Secondo il MIUR, nell’anno scolastico 2006-2007, gli studenti stranieri nella scuola italiana, provenienti da circa 190 paesi, hanno superato, anche se di poco, quota 500.000 (circa il 5,6% degli studenti). Il percorso verso l’integrazione scolastica è tortuoso: in difficoltà appaiono le strutture che li accolgono e gli stessi insegnanti, che devono gestire un gruppo-classe di italofoni secolarizzati e di studenti stranieri da un profilo ben poco delineato. I dati sui comportamenti linguistici di questi allievi rivelano quanto siano diversi i tempi dell’acquisizione dell’italiano per la comunicazione quotidiana e interpersonale, rispetto a quella per lo studio. Come evidenziato da Cummins, le abilità comunicative di base (BICS) e la competenza linguistica cognitivo-accademica (CALP) si sviluppano in tempi molto diversi: le prime dai 6 mesi ai due anni; le seconde, invece, in un periodo che va dai 5 ai 7 anni. Per comprendere e usare la L2 per lo studio, l’apprendente straniero deve acquisire competenze diverse, di tipo linguistico, testuale, culturale, oltre che di tipo cognitivo e informativo. E’ qui che si inserisce il nostro lavoro, tentativo di esplorare strategie glottodidattiche e pedagogiche capaci di rinforzare le abilità dell’allievo rispetto ai compiti cognitivi e linguistici richiesti dallo studio delle discipline scolastiche. L’obiettivo è far sì che l’allievo raggiunga, attraverso l’italiano, una buona autonomia nello studio e in tutti quei casi in cui dovrà affrontare testi complessi in contesti extra-scolastici.

description: INTRODUCTION: A stressful practice environment may harm the physical well-being and psychological health of nurses, which, in turn, may lead to a reduction in nurses' work engagement level. This study aimed to determine the relationship between practice environment and work engagement among nurses in selected Ministry Academic Hospitals in Saudi Arabia.

METHODS: This cross-sectional study utilized a descriptive, comparative, and correlation research design. Ethical clearance was secured accordingly. Three hundred forty-three (N=343) nurses from the selected Ministry Academic Hospitals in Saudi Arabia participated. Data were gathered systematically using a demographic questionnaire, the Practice Environment Scale of the Nurse Work Index (PES-NWI) of Lake (2002), and the Utrecht Work Engagement Scale-9 (UWES-9). IBM-SPSS Statistics version 27 was used to analyze the data. Frequency counts and percentages were used to characterize the nurses' demographic and work-related profile. The overall PES-NWI "composite" score was computed as the mean of the five subscale scores. Spearman correlation and point-biserial correlation were used to determine the relationships between variables of interest. An alpha level of 0.5 was used to interpret the significance.

RESULTS:  There was a statistically significant moderate positive relationship between nurse participation in hospital affairs and work engagement (rs=.451, p=.000), a statistically significant weak positive correlation between nursing foundations of quality of care and work engagement (rs=.388, p =.000), nurse manager ability, leadership and support of nurses, and work engagement, (rs=.378, p =.000), staffing and resource adequacy and work engagement, (rs=.350, p=.000), and collegial nurse-physician relationships and work engagement, (rs=.296, p=.000).

CONCLUSION: There is a statistically significant moderate positive relationship between overall perceived nurses’ practice environment and level of work engagement (rs=.454, p=.000).

RECOMMENDATIONS: The findings of this study will serve as baseline data to guide hospital and Nurse leaders on where to focus attention in improving the patient care environment. It recommended devising more strategies and activities to improve the practice environment to promote work engagement among nurses.
The Heterotic Green-Schwarz Superstring on an N=(2,0) Super-Worldsheet

description: By defining the heterotic Green-Schwarz superstring action on an N=(2,0) super-worldsheet, rather than on an ordinary worldsheet, many problems with the interacting Green-Schwarz superstring formalism can be solved. In the light-cone approach, superconformally transforming the light-cone super-worldsheet onto an N=(2,0) super-Riemann surface allows the elimination of the non-trivial interaction-point operators that complicate the evaluation of scattering amplitudes. In the Polyakov approach, the ten-dimensional heterotic Green-Schwarz covariant action defined on an N=(2,0) super-worldsheet can be gauge-fixed to a free-field action with non-anomalous N=(2,0) superconformal invariance, and integrating the exponential of the covariant action over all punctured N=(2,0) super-Riemann surfaces produces scattering amplitudes that closely resemble amplitudes obtained using the unitary light-cone approach.

description: The foundation for any discussion of first-order phse transitions is Classical Nucleation Theory(CNT). CNT, developed in the first half of the twentieth century, is based on a number of heuristically plausible assumtptions and the majority of theoretical work on nucleation is devoted to refining or extending these ideas. Ideally, one would like to derive CNT from a more fundamental description of nucleation so that its extension, development and refinement could be developed systematically. In this paper, such a development is described based on a previously established (Lutsko, JCP 136:034509, 2012 ) connection between Classical Nucleation Theory and fluctuating hydrodynamics. Here, this connection is described without the need for artificial assumtions such as spherical symmetry. The results are illustrated by application to CNT with moving clusters (a long-standing problem in the literature) and the constructrion of CNT for ellipsoidal clusters.

description: The Mesozoic tectonic transition from the Palaeo-Tethys tectonic regime to the Palaeo-Pacific tectonic regime in the eastern South China Block has long been debated. Geochemical and zircon U–Pb–Hf isotopic studies were conducted on the Dashuang complex in the eastern Zhejiang Province. The Dashuang complex consists mainly of quartz syenite in the northwestern part and quartz monzonite in the southeastern part. New laser ablation inductively coupled plasma mass spectrometry zircon U–Pb data show that the quartz syenite, the quartz monzonite, and its chilled margin (fine-grained granite) crystallized at 235 ± 4 Ma, 232 ± 3 Ma, and 230 ± 1 Ma, respectively. The Dashuang complex intrudes into the Chencai Group gneiss that postdated ~646 Ma and underwent anatexis at 443 ± 14 Ma. The quartz monzonite shows A-type granite affinity, characterized by high K2O + Na2O and Zr + Nb + Ce + Y, high FeOT/(MgO + FeOT) and Ga/Al ratios, an enrichment in light rare earth elements, and depletions in Ba, Sr, and Eu. The quartz monzonite has zircon εHf(t) values of −14.2 to –11.9 and two-stage model ages of 1788–1922 Ma. Zircon εHf(t) values of the chilled margin (fine-grained granite) and wall rock (gneiss) are scattered (−18.2 to –6.3 and −19.5 to 10.2). The corresponding two-stage model ages are 1482–2133 Ma and 1184–2471 Ma, respectively. The Dashuang complex was derived mainly from partial melting of Neoproterozoic clastic rocks in the Cathaysia Block. Geochemical data indicate that the quartz monzonite formed in a post-collision extensional environment. These results, considered with previous data, indicate that the transition from the Palaeo-Tethys to the Palaeo-Pacific tectonic regimes of the eastern South China Block occurred during the Late Triassic (225–215 Ma).
The role of AGN feedback on the evolution of dwarf galaxies from cosmological simulations: SMBHs suppress star formation in low-mass galaxies

description: Aims. Recent observational studies suggest that feedback from active galactic nuclei (AGNs) may play an important role in the formation and evolution of low-mass dwarf galaxies, an issue that has received little attention from a theoretical perspective. Methods. We investigate this using two sets of 12 cosmological magneto-hydrodynamical simulations of the formation of dwarf galaxies: one set using a version of the AURIGA galaxy formation physics model including AGN feedback and a parallel set with AGN feedback turned off. Results. We show that the full-physics AGN runs satisfactorily reproduce several scaling relations, including the M_ BH-M_*, M_ BH-sigma_* and the baryonic Tully-Fisher relation. We find that the global star formation (SF) of galaxies run with AGN is reduced compared to the one in which AGN has been turned off, suggesting that this type of feedback is a viable way of suppressing SF in low-mass dwarfs, even though none of our galaxies is completely quenched by z=0. Furthermore, we found a tight correlation between the median SF rates and the black-hole-to-stellar mass ratio (M_BH/M_star) in our simulated dwarfs. SF is suppressed due to gas heating in the vicinity of the AGN: less HI gas is available in AGN runs, though the total amount of gas is preserved across the two settings within each galaxy. This indicates that the main effect of AGN feedback in our dwarfs is to heat up and push the gas away from the galaxy's centre rather than expelling it completely. Finally, we show that the two galaxies harbouring the largest BHs have suffered a considerable (up to 65%) reduction in their central dark matter density, pinpointing the role of AGNs in determining the final dark matter mass distribution within dwarf galaxies. This pilot paper highlights the importance of modelling AGN feedback at the lowest mass scales and the impact this can have on dwarf galaxy evolution.

description: In this paper, we study the production of isolated-photon plus a jet in $pp$ and $PbPb$ collisions, which can be used as an important probe to the jet transport property in quark gluon plasma created in heavy ion collisions. Normally, there are two types of observables associated with the production of isolated-photon plus a jet, namely, the azimuthal angular correlation and the transverse momentum imbalance. To understand both observables in the full kinematical region, we need to employ the perturbative QCD calculation, which takes into account the hard splitting of partons, together with the Sudakov resummation formalism, which resums soft gluon splittings. Furthermore, by introducing energy-loss into the system, we calculate the enhancement of the momentum imbalance distribution for $AA$ as compared to $pp$ collisions and make predictions for future unfolded experimental data. In addition, in order to extract the jet transport coefficient more precisely in our numerical calculation, we also distinguish quark jets from gluon jets, since they interact with quark gluon plasma with different strengths. This work provides a reliable theoretical tool for the calculation of the gamma-jet correlation, which can lead us to a more precise extraction of the jet transport coefficient in relativistic heavy-ion collisions.

In characteristic zero, i.e. when A is an algebra over the rational numbers, a minimal set of generators has been known since the 19th century. A rather small generating set in the general case has also recently been given by Vaccarino but it is not minimal in general. We also give a sharp degree bound on the generators, improving the degree bound previously obtained by Fleischmann.

description: Антропный принцип, проведенный последовательно в экономическом знании, позволяет обосновать сущность проблем в экономике любой страны как проблем именно человеческих, а не технических или ресурных. Кризисы перепроизводства получают новое объяснение своей неизбежности: производство способностей оказывается не восполненным уровнями потребностей производителей. Так устраняется стереотип восприятия потребностей в качестве некоего абсолюта, ограниченного лишь уровнем дохода населения. Духовное производство, то есть производство идеальных продуктов, знаний в единстве с навыками и умениями, есть главный источник преодоления неизбежности кризисов перепроизводства, поскольку способно коренным образом изменить традиции и обычаи, укрепляющие устойчивость всех производительных сил.

description: Interaction with others influences our opinions and behaviours. Our activities within various social circles lead to different opinions expressed in various situations, groups, and ways of communication. Earlier studies on agent-based modelling of conformism within networks were based on a single-layer approach. Contrary to that, in this work, we propose a model incorporating conformism in which a person can share different continuous opinions on different layers depending on the social circle. Afterwards, we extend the model with more components that are known to influence opinions, e.g. authority or openness to new views. These two models are then compared to show that only sole conformism leads to opinion convergence.

description: Uno studio generale del linguaggio e delle lingue non può fare a meno di considerare l'aspetto pragmatico, l'uso linguistico, che oltre ad essere un importante indice del grado di vitalità e di buona salute di una certa lingua è condizione della sua stessa sopravvivenza. Senza dubbio nell'universo della scrittura letteraria ritroviamo l'organizzazione più complessa dei segni linguistici. La scrittura, infatti, con la sua capacità di inventiva, con la sua tendenza ad arricchire una stessa parola di interpretanti, di sensi e di significati nuovi o meno ovvi, riveste un ruolo importante nel plurilinguismo, attributo essenziale delle lingue: sia nella molteplicità dei linguaggi all'interno di una stessa lingua, sia nei rapporti di interazione e di scambio tra lingue diverse. Tale prerogativa della scrittura permette alla lingua di trovare una realizzazione più piena, più vicina alla capacità di linguaggio che caratterizza la specie umana, andando ben al di là dei suoi limiti strutturali, delle sue regole.

Ένας καταλυτικός παράγοντας επιβάρυνσης είναι οι εκπομπές CO2 στην ατμόσφαιρα, και κατά συνέπεια, όλες οι ανθρώπινες πρακτικές με αυξημένη παραγωγή CO2 πρέπει να περιοριστούν. Στον κατασκευαστικό κλάδο, η τσιμεντοβιομηχανία προσπαθεί να συμβάλει σε αυτή την οικουμενική προσπάθεια μειώνοντας τις εκπομπές CO2 από την παραγωγή τσιμέντου χρησιμοποιώντας βιομηχανικά υποπροϊόντα ως εναλλακτικά καύσιμα και αναπτύσσοντας δευτερογενή προϊόντα σκυροδέματος από απόβλητα κατασκευών. Με αυτές τις προσπάθειες, η τσιμεντοβιομηχανία προσπαθεί να γίνει πιο φιλική προς το περιβάλλον και να μειώσει την περιβαλλοντική επιβάρυνση. Στην παρούσα μελέτη αναλύθηκε η δυνατότητα χρήσης ανόργανων κατασκευαστικών αποβλήτων για την παραγωγή φιλικού προς το περιβάλλον ανακυκλωμένου τσιμέντου με τη διαδικασία της αναλογίας και για το σκοπό αυτό, αναλύθηκαν οι τύποι και οι τάσεις παραγωγής ανακυκλώσιμων οικοδομικών αποβλήτων για την ανάπτυξη ανακυκλωμένου τσιμέντου με τη χρήση τέτοιων οικοδομικών αποβλήτων (Adesanya & Raheem, 2009). Για την συλλογή των δεδομένων της παρούσας μελέτης και με βάση αυτή την ανάλυση, επιλέχθηκαν ανακυκλώσιμα ανόργανα κατασκευαστικά απόβλητα και συλλέχθηκαν πραγματικά απόβλητα. Η χημική σύνθεση κάθε ανόργανου κατασκευαστικού αποβλήτου αναλύθηκε με τη χρήση φθορισμού ακτίνων Χ και η σύνθεση του συνηθισμένου εμπορικού τσιμέντου χρησιμοποιήθηκε ως βάση. Αφού αναμείχθηκαν τα συλλεχθέντα ανόργανα απόβλητα κατασκευών, ψήθηκαν χρησιμοποιώντας τον τύπο Bogue, ενώ εν συνεχεία τα ορυκτά συστατικά του κλίνκερ, το οποίο προέκυψε από τη διαδικασία της όπτησης, προβλέφθηκαν και αναλύθηκαν.

Cosa si intende per didattica interculturale? Quali strategie didattiche adottare per portare gli studenti all’acquisizione della competenza comunicativa interculturale? Quali proposte per contesti di italiano LS? Questo intervento propone possibili risposte a queste domande attraverso la presentazione di un percorso didattico sperimentato con studenti messicani, partendo dall’ipotesi che per iniziare a sviluppare la competenza comunicativa interculturale, nucleo della didattica in prospettiva interculturale, si debba partire da un lavoro in classe che porti gli studenti ad assumere consapevolezza del proprio “software mentale”. Questo lavoro va considerato come passaggio imprescindibile per arrivare a comunicare efficacemente con l’altro diverso da sé.

description: Oogenesis in the urochordate, Oikopleura dioica, occurs in a large coenocyst in which vitellogenesis precedes oocyte selection in order to adapt oocyte production to nutrient conditions. The animal has expanded CDK1 and Cyclin B paralog complements, with several expressed during oogenesis. Here, we addressed functional redundancy and specialization of CDK1 and cyclin B paralogs during oogenesis and early embryogenesis through spatiotemporal analyses and knockdown assays. CDK1a translocated from organizing centres (OCs) to selected meiotic nuclei at the beginning of the P4 phase of oogenesis, and its knockdown impaired vitellogenesis, nurse nuclear dumping, and entry of nurse nuclei into apoptosis. CDK1d-Cyclin Ba translocated from OCs to selected meiotic nuclei in P4, drove meiosis resumption and promoted NEBD. CDK1d-Cyclin Ba was also involved in histone H3S28 phosphorylation on centromeres and meiotic spindle assembly through regulating Aurora B localization to centromeres during prometaphase I. In other studied species, Cyclin B3 commonly promotes anaphase entry, but we found O. dioica Cyclin B3a to be non-essential for anaphase entry during oogenic meiosis. Instead, Cyclin B3a contributed to meiotic spindle assembly though its loss could be compensated by Cyclin Ba.

description: Entanglement plays a crucial role in the development of quantum-enabled devices. One significant objective is the deterministic creation and distribution of entangled states, achieved, for example, through a mechanical oscillator interacting with confined electromagnetic fields. In this study, we explore a cavity resonator containing a two-sided perfect mirror. Although the mirror separates the cavity modes into two independent confined electromagnetic fields, the radiation pressure interaction gives rise to high-order effective interactions across all subsystems. Depending on the chosen resonant conditions, which are also related to the position of the mirror, we study $2n$-photon entanglement generation and bilateral photon pair emission. Demonstrating the non-classical nature of the mechanical oscillator, we provide a pathway to control these phenomena, opening potential applications in quantum technologies. Looking ahead, similar integrated devices could be used to entangle subsystems across vastly different energy scales, such as microwave and optical photons.

description: I study the Ward identities of the $w_\infty$ symmetry of the two-dimensional string theory. It is found that, not just an isolated vertex operator, but also a number of vertex operators colliding at a point can produce local charge non-conservation. The structure of all such contact terms is determined. As an application, I calculate all the non-vanishing bulk tachyon amplitudes directly through the Ward identities for a Virasoro subalgebra of the $w_\infty$.

description: Targeting macroautophagy/autophagy is a novel strategy in cancer immunotherapy. In the present study, we showed that the natural product rocaglamide (RocA) enhanced natural killer (NK) cell-mediated lysis of non-small cell lung cancer (NSCLC) cells in vitro and tumor regression in vivo. Moreover, this effect was not related to the NK cell recognition of target cells or expressions of death receptors. Instead, RocA inhibited autophagy and restored the level of NK cell-derived GZMB (granzyme B) in NSCLC cells, therefore increasing their susceptibility to NK cell-mediated killing. In addition, we further identified that the target of RocA was ULK1 (unc-51 like autophagy activating kinase 1) that is required for autophagy initiation. Using firefly luciferase containing the 5´ untranslated region of ULK1, we found that RocA inhibited the protein translation of ULK1 in a sequence-specific manner. Taken together, RocA could block autophagic immune resistance to NK cell-mediated killing, and our data suggested that RocA was a promising therapeutic candidate in NK cell-based cancer immunotherapy.

description: Propagation of transient mechanical waves in porous media is numerically investigated in 1D. The framework is the linear Biot's model with frequency-independant coefficients. The coexistence of a propagating fast wave and a diffusive slow wave makes numerical modeling tricky. A method combining three numerical tools is proposed: a fourth-order ADER scheme with time-splitting to deal with the time-marching, a space-time mesh refinement to account for the small-scale evolution of the slow wave, and an interface method to enforce the jump conditions at interfaces. Comparisons with analytical solutions confirm the validity of this approach.

description: We evaluated the viability of using Large Language Models (LLMs) to trigger and personalize content in Just-in-Time Adaptive Interventions (JITAIs) in digital health. As an interaction pattern representative of context-aware computing, JITAIs are being explored for their potential to support sustainable behavior change, adapting interventions to an individual's current context and needs. Challenging traditional JITAI implementation models, which face severe scalability and flexibility limitations, we tested GPT-4 for suggesting JITAIs in the use case of heart-healthy activity in cardiac rehabilitation. Using three personas representing patients affected by CVD with varying severeness and five context sets per persona, we generated 450 JITAI decisions and messages. These were systematically evaluated against those created by 10 laypersons (LayPs) and 10 healthcare professionals (HCPs). GPT-4-generated JITAIs surpassed human-generated intervention suggestions, outperforming both LayPs and HCPs across all metrics (i.e., appropriateness, engagement, effectiveness, and professionalism). These results highlight the potential of LLMs to enhance JITAI implementations in personalized health interventions, demonstrating how generative AI could revolutionize context-aware computing.
Mesoscopic real space structures in aging spin-glasses: the Edwards-Anderson model

description: Isothermal simulational data for the 3D Edwards-Anderson spin glass are collected at several temperatures below $T_{\rm c}$ and, in analogy with a recent model of dense colloidal suspensions,interpreted in terms of clusters of contiguous spins overturned by quakes, non-equilibrium events linked to record sized energy fluctuations. We show numerically that, to a good approximation, these quakes are statistically independent and constitute a Poisson process whose average grows logarithmically in time. The overturned clusters are local projections on one of the two ground states of the model, and grow likewise logarithmically in time. Data collected at different temperatures $T$ can be collapsed by scaling them with $T^{1.75}$, a hitherto unnoticed feature of the E-A model, which we relate on the one hand to the geometry of configuration space and on the other to experimental memory and rejuvenation effects. The rate at which a cluster flips is shown to decrease exponentially with the size of the cluster, as recently assumed in a coarse grained model of dense colloidal dynamics. The evolving structure of clusters in real space is finally sssociated to the decay of the thermo-remanent magnetization. Our analysis provides an unconventional coarse-grained description of spin glass aging as statistically subordinated to a Poisson quaking process and highlights record dynamics as a viable common theoretical framework for aging in different systems.

description: A model consisting of oxygen-occupied and -vacant chains is considered, with repulsive first and second nearest-neighbor interactions V1 and V2, respectively. The statistical mechanics and the diffraction spectrum of the model is solved exactly and analytically with the only assumption V1 >> V2. At temperatures T ~ V1 only a broad maximum at (1/2,0,0) is present, while for ABS(delta - 1/2) > 1/14 at low enough T, the peak splits into two. The simple expression for the diffraction intensity obtained for T << V1 represents in a more compact form previous results of Khachaturyan and Morris[1],extends them to all delta and T/V2 and leads to a good agreement with experiment.

description: Using Schroedinger functional techniques, we determine the coefficient of the clover term necessary for non-perturbative O(a) improvement of hypercubic smeared Wilson fermions on a quenched plaquette action background. Unlike for unsmeared Wilson fermions, the resulting clover coefficients are close to the tree-level value even at coarse lattice spacings, indicating the absence of large cutoff effects. A number of exploratory tests are also performed with the improved action.

description: Σκοπό της παρούσας διπλωματικής εργασίας αποτέλεσε η εμβάθυνση και η αναζήτηση των επιπτώσεων του θεσμού της άρσης αυτοτέλειας της νομικής προσωπικότητας, καθώς και η εξέταση της λειτουργίας του στην ελληνική έννομη τάξη και κατ’ επέκταση στην εγχώρια αγορά. Καθώς δεν έχει στο παρελθόν διενεργηθεί στην Ελλάδα, μία νομική και οικονομική ανάλυση της προβληματικής της άρσης αυτοτέλειας της νομικής προσωπικότητας, βασικό μέλημα της παρούσας διπλωματικής εργασίας ήταν να προσεγγίσει το μηχανισμό από μία «law and economics» σκοπιά. Υπό το πρίσμα των ανωτέρω, εξετάστηκαν διεξοδικά τα κριτήρια που χρησιμοποιούν τα ελληνικά δικαστήρια για την διάγνωση της κατάχρησης του θεσμού της εταιρείας, η οικονομική λογική που κρύβεται πίσω από αυτά, το πως εφαρμόζονται από τα ελληνικά δικαστήρια και τι επιχειρηματολογία χρησιμοποιείται για να δικαιολογηθεί η εφαρμογή τους, σε ποιο βαθμό οι Έλληνες δικαστές αντιλαμβάνονται την οικονομική λογική ώστε να εφαρμόσουν τα εν λόγω κριτήρια, καθώς και οι επιπτώσεις (θετικές και αρνητικές) των κριτηρίων αυτών και του μηχανισμού της άρσης αυτοτέλειας της νομικής προσωπικότητας εν γένει. Επιπλέον, μέσω της παρούσας διπλωματικής εργασίας, επιχειρήθηκε να απαντηθούν σημαντικά ερωτήματα, όπως παραδείγματος χάριν κατά πόσον τα ελληνικά δικαστήρια λαμβάνουν υπόψη τις συνεχώς μεταβαλλόμενες συνθήκες της αγοράς, όταν καλούνται να εφαρμόσουν τον μηχανισμό της άρσης της αυτοτέλειας της νομικής προσωπικότητας ή σε ποιο βαθμό οι συμμετέχοντες στην αγορά – οι επιχειρηματίες – λαμβάνουν υπόψη τους την ύπαρξη και λειτουργία του εν λόγω μηχανισμού. Τα «εργαλεία» που χρησιμοποιήθηκαν για την συγγραφή της παρούσας και την επιβεβαίωση ή απόρριψη των Ερευνητικών Υποθέσεων, ήταν η εμπειρική και η ποσοτική έρευνα, μέσω ερωτηματολογίου. Η λήψη αποφάσεών των υποκειμένων της αγοράς και ειδικότερα των επιχειρηματιών, είναι ανεξάρτητη από οποιαδήποτε έννομη συνέπεια ή κινδύνους και εξωτερικές επιδράσεις; Υφίσταται πραγματικός κίνδυνος από την ύπαρξη και εφαρμογή του μηχανισμού της άρσης του εταιρικού «μανδύα» στην αγορά, να δημιουργούνται αλλοιώσεις και να επηρεάζονται θετικά ή αρνητικά η επιχειρηματική στρατηγική και οι αποφάσεις των συμμετεχόντων σε αυτή, ενώ ο θεσμός κατά τα λοιπά αποτελεί ένα οικονομικά αποτελεσματικό μέτρο, καθώς μπορεί να συμβάλει σε μεγαλύτερη προβλεψιμότητα στις συναλλαγές και στη μείωση του κόστους συναλλαγών; Μήπως παράλληλα με όλα τα ανωτέρω αλλοιώνεται και επηρεάζεται ο ανταγωνισμός;
