description: We study numerically the nonequilibrium dynamical behavior of an Ising model with mixed two-spin and four-spin interactions after a sudden quench from the high-temperature phase to the first-order phase transition point. The autocorrelation function is shown to approach its limiting value, given by the magnetization in the ordered phase at the transition point, m_c, through a stretched exponential decay. On the other hand relaxation of the magnetization starting with an uncorrelated initial state with magnetization, m_i, approaches either m_c, for m_i>0.5, or zero, for m_i<0.5. For small m_i and for m_i slightly larger than 0.5 the relaxation of the magnetization shows an asymptotic power-law time dependence, thus from a nonequilibrium point of view the transition is continuous.

description: Kainate induces a marked expression of cyclooxygenase-2 after its systemic administration. Because cyclooxygenase-2 activity is associated to the production of reactive oxygen species, we investigated the effects of nimesulide, a selective cyclooxygenase-2 inhibitor, on kainate-induced in vivo oxidative damage in the rat hippocampus. A clinically relevant dose of nimesulide (6 mg/kg, i.p.) was administered three times following kainate application (9 mg/kg, i.p.). After 24 h of kainate administration, the drastic decrease in hippocampal glutathione content and the significant increase in lipid peroxidation were attenuated in nimesulide-treated rats, suggesting that the induction of cyclooxygenase-2 is involved in kainate-mediated free radicals formation.

description: Automatic speaker diarization techniques typically involve a two-stage processing approach where audio segments of fixed duration are converted to vector representations in the first stage. This is followed by an unsupervised clustering of the representations in the second stage. In most of the prior approaches, these two stages are performed in an isolated manner with independent optimization steps. In this paper, we propose a representation learning and clustering algorithm that can be iteratively performed for improved speaker diarization. The representation learning is based on principles of self-supervised learning while the clustering algorithm is a graph structural method based on path integral clustering (PIC). The representation learning step uses the cluster targets from PIC and the clustering step is performed on embeddings learned from the self-supervised deep model. This iterative approach is referred to as self-supervised clustering (SSC). The diarization experiments are performed on CALLHOME and AMI meeting datasets. In these experiments, we show that the SSC algorithm improves significantly over the baseline system (relative improvements of 13% and 59% on CALLHOME and AMI datasets respectively in terms of diarization error rate (DER)). In addition, the DER results reported in this work improve over several other recent approaches for speaker diarization.

description: This volume covers Leg 46 of the cruises of the Drilling Vessel Glomar Challenger. The Glomar Challenger sailed on Leg 46 from San Juan, Puerto Rico, on 28 January 1976. Legs 45 and 46 were to be the first cruise of IPOD (International Program of Ocean Drilling) to drill a very deep multiple re-entry hole near the Mid-Atlantic Ridge axis. This hole was to be the first of a longitudinal Atlantic transect planned by the JOIDES Ocean Crust Panel. Leg 46 drilled two holes (396A and 396B) in a sediment pond about 150 km east of the Mid-Atlantic Ridge at 22°59.14'N, 43°30.90'W. Leg 45 had previously drilled Hole 396 to about 100 meters into basement in the sediment pond. Hole 396A was a mudline test with only 0.64 meters recovered from the two cores taken at the top of the sediment column. Hole 396B was a multiple re-entry hole which penetrated 150.5 meters of sediment and 205 meters into basaltic basement.

description: We analytically and numerically study the probabilistic properties of inverted and mirror repeats in model sequences of nucleic acids. We consider both perfect and non-perfect repeats, i.e. repeats with mismatches and gaps. The considered sequence models are independent identically distributed (i.i.d.) sequences, Markov processes and long range sequences. We show that the number of repeats in correlated sequences is significantly larger than in i.i.d. sequences and that this discrepancy increases exponentially with the repeat length for long range sequences.

description: Crashing ocean waves, cappuccino froths and microfluidic bubble crystals are examples of foamy flows. Foamy flows are critical in numerous natural and industrial processes and remain notoriously difficult to compute as they involve coupled, multiscale physical processes. Computations need to resolve the interactions of the bubbles with the fluid and complex boundaries, while capturing the drainage and rupture of the microscopic liquid films at their interface. We present a novel multilayer simulation framework (Multi-VOF) that advances the state of the art in simulation capabilities of foamy flows. The framework introduces a novel scheme for the distinct handling of multiple neighboring bubbles and a new regularization method that produces sharp interfaces and removes spurious fragments. Multi-VOF is verified and validated with experimental results and complemented with open source, efficient scalable software. We demonstrate capturing of bubble crystalline structures in realistic microfluidics devices and foamy flows involving tens of thousands of bubbles in a waterfall. The present multilayer framework extends the classical volume-of-fluid methodology and allows for unprecedented large scale, predictive simulations of flows with multiple interfaces.

The theoretical and practical foundations of strong earthquake predictability

description: This paper provides theoretical and practical arguments regarding the possibility of predicting strong and major earthquakes worldwide. Many strong and major earthquakes can be predicted at least two to five months in advance, based on identifying stressed areas that begin to behave abnormally before strong events, with the size of these areas corresponding to Dobrovolsky formula. We make predictions by combining knowledge from many different disciplines: physics, geophysics, seismology, geology, and earth science, among others. An integrated approach is used to identify anomalies and make predictions, including satellite remote sensing techniques and data from ground-based instruments. Terabytes of information are currently processed every day with many different multi-parametric prediction systems applied thereto. Alerts are issued if anomalies are confirmed by a few different systems. It has been found that geophysical patterns of earthquake preparation and stress accumulation are similar for all key seismic regions. The same earthquake prediction methodologies and systems have been successfully applied in global practice since 2013, with the technology successfully used to retrospectively test against more than 700 strong and major earthquakes since 1970.

description: Next-generation, high-brilliance x-ray photon sources call for new x-ray optics. Here we demonstrate the feasibility of using monolithic diamond channel-cut crystals as high-heat-load, beam-multiplexing, narrow-band, mechanically-stable x-ray monochromators with high-power x-ray beams at cutting-edge, high-repetition-rate x-ray free-electron laser (XFEL) facilities. The diamond channel-cut crystals fabricated and characterized in these studies are designed as two-bounce Bragg reflection monochromators directing 14.4-keV or 12.4-keV x-rays within a 15-meV-bandwidth to $^{57}$Fe or $^{45}$Sc nuclear resonant scattering experiments, respectively. The crystal design allows out-of-band x-rays within a $\simeq 1$-eV XFEL bandwidth to be transmitted with minimal losses to alternative simultaneous experiments. Only $\lesssim 2$\% of the incident $\simeq 100$-W x-ray beam is absorbed in a 50-$μ$m-thick first diamond crystal reflector, ensuring that the monochromator crystal is highly stable. Other x-ray optics applications of diamond channel-cut crystals are anticipated.

description: A new precision measurement of the parity violating analyzing power in longitudinally polarized electron scattering from the proton at very low Q^2 at an incident energy of 1.16 GeV is in the final stages of preparation for execution at Jefferson Laboratory (JLab). A 2200 hour measurement of the parity violating asymmetry in elastic electron-proton scattering at Q^2 = 0.03 (GeV/c)^2 employing 180 microamp of 85% polarized beam on a 0.35 m long liquid hydrogen target will determine the weak charge of the proton, Q_w = 1 - 4sin^2(theta_W), with 4% combined statistical and systematic errors. The Standard Model makes a firm prediction of Q_w, based on the `running' of the weak mixing angle sin^2(theta_W) from the Z-pole down to lower energies. Any significant deviation of sin^2(theta_W) from its Standard Model prediction at low Q^2 would constitute a signal of new physics. In the absence of new physics, the envisaged experiment will provide a 0.3% determination of sin^2(theta_W), making this a very competitive measurement of the weak mixing angle. Complementary to the present experiment is a measurement of the weak charge of the electron in parity violating Moller scattering at 11 GeV, currently under consideration, with the upgraded CEBAF at JLab. The objective of that experiment would be a measurement of sin2(theta_W) with a precision comparable to or better than any individual measurement at the Z-pole.

description: Packet-switching WDM ring networks with a hotspot transporting unicast, multicast, and broadcast traffic are important components of high-speed metropolitan area networks. For an arbitrary multicast fanout traffic model with uniform, hotspot destination, and hotspot source packet traffic, we analyze the maximum achievable long-run average packet throughput, which we refer to as \textit{multicast capacity}, of bi-directional shortest-path routed WDM rings. We identify three segments that can experience the maximum utilization, and thus, limit the multicast capacity. We characterize the segment utilization probabilities through bounds and approximations, which we verify through simulations. We discover that shortest-path routing can lead to utilization probabilities above one half for moderate to large portions of hotspot source multi- and broadcast traffic, and consequently multicast capacities of less than two simultaneous packet transmissions. We outline a one-copy routing strategy that guarantees a multicast capacity of at least two simultaneous packet transmissions for arbitrary hotspot source traffic.

description: Time-dependent cooling processes are of paramount importance in the evolution of astrophysical gaseous nebulae and, in particular, when radiative shocks are present. The present work introduces a necessary set of tools that can be used to model radiative astrophysical flows in the optically-thin plasma limit. We aim to provide reliable and accurate predictions of emission line ratios and radiative cooling losses in astrophysical simulations of shocked flows. Moreover, we discuss numerical implementation aspects to ease future improvements and implementation in other MHD numerical codes. The most important source of radiative cooling for our plasma conditions comes from the collisionally-excited line radiation. We evolve a chemical network, including 29 ion species, to compute the ionization balance in non-equilibrium conditions. After a series of validations and tests, typical astrophysical setups are simulated in 1D and 2D, employing both the present cooling model and a simplified one. The influence of the cooling model on structure morphologies can become important, especially for emission line diagnostic purposes.

description: Early Childhood Mental Health Consultation (ECMHC) promotes young children's school readiness by building the capacity of the adults and systems with whom they interact. In ECMHC, consultants may work with teachers to increase their use of behaviors that enhance classroom management and teacher-child relationships, which are in turn linked to the development of children's social-emotional competence. Motivational Interviewing (MI) can be incorporated to increase teachers’ motivation to implement and maintain these behaviors. The proposed study will examine the effects of ECMHC and MI on teacher behaviors and secondary child-related outcomes using a multiple-baseline single case design. Outcomes will be analyzed using visual inspection and calculating a single-case design effect size.

description: Map-making presents a significant computational challenge to the next generation of kilopixel CMB polarisation experiments. Years worth of time ordered data (TOD) from thousands of detectors will need to be compressed into maps of the T, Q and U Stokes parameters. Fundamental to the science goal of these experiments, the observation of B-modes, is the ability to control noise and systematics. In this paper, we consider an alternative to the maximum-likelihood method, called destriping, where the noise is modelled as a set of discrete offset functions and then subtracted from the time-stream. We compare our destriping code (Descart: the DEStriping CARTographer) to a full maximum-likelihood map-maker, applying them to 200 Monte-Carlo simulations of time-ordered data from a ground based, partial-sky polarisation modulation experiment. In these simulations, the noise is dominated by either detector or atmospheric 1/f noise. Using prior information of the power spectrum of this noise, we produce destriped maps of T, Q and U which are negligibly different from optimal. The method does not filter the signal or bias the E or B-mode power spectra. Depending on the length of the destriping baseline, the method delivers between 5 and 22 times improvement in computation time over the maximum-likelihood algorithm. We find that, for the specific case of single detector maps, it is essential to destripe the atmospheric 1/f in order to detect B-modes, even though the Q and U signals are modulated by a half-wave plate spinning at 5-Hz.

Despite considerable efforts, we do not have yet a full and compelling picture of such backgrounds. We review some of the various attempts to understand these singularities via generalizations of the BKL dynamics, using worldsheet methods and using non-perturbative tools such as the AdS/CFT correspondence and M(atrix) theory. These lecture notes are based on talks given at Cargese 06 and the dead-sea conference 06.

On the robustness of holonomic quantum computation
Creators: name: Lupo, Cosmo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: Besides standard dynamical schemes to realize a quantum computer, there are particular approaches which are based on intrinsic properties of quantum systems, leading to the definition of topological computation and holonomic, or geometric, computation. The holonomic approach can
be viewed as the application of non-Abelian geometric phases to quantum information processing, it is believed to be fault-tolerant with respect of certain kind of parametric noise. Here we discuss the issue of robustness of holonomic quantum gates under parametric noise: we distinguish between geometric and dynamical effects of cancelation, which can appear in different contexts. A so-called standard argument in favor of the stability of noisy holonomic quantum gates is reviewed and extended
to more general settings. New geometric effects that describe the behavior of noisy holonomic gates are presented. These effects lead to a refining of the optimal strategy to achieve a robust computation.

"Docetaxel in adjuvant therapy of breast cancer: results of the TAXIT 216 multicenter trial"
Creators: name: Forestieri, Valeria
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: The dissertation is focused on the evaluation of a Docetaxel-based
sequential regimen as adjuvant therapy of breast cancer.
Docetaxel is among the most active chemotherapeutic agents for breast
cancer. With Taxit 216 trial, we aimed to assess the efficacy of adding
docetaxel in a block-sequential fashion to a regimen with doxorubicin followed
by CMF in the adjuvant therapy for node-positive early stage breast cancer
(ESBC).
Patients were randomized to arm A (epirubicin 120 mg/m2 for 4 cycles then
cyclophosphamide, methotrexate and 5-fluorouracil [CMF] for 4 cycles), or
arm B (4 cycles of docetaxel 100 mg/m2 administered after the fourth
epirubicin cycle and before the first CMF cycle). Treatment allocation was
performed, in our Institution, by a computer program using a minimization
algorithm. Stratification factors were: center, lymph node involvement (1 to 3,
4 to 9, >10), estrogen receptor status (negative/positive/unknown), menopausal
status (pre/post). The primary end-point was invasive disease-free survival
(IDFS). Secondary end-points were recurrence-free survival (RFS), overall
survival (OS) and toxicity. The study was designed to detect a hazard ratio of
0.70, assuming an a of 0.05 (two-sided), a power of 0.80 and an expected DFS
in arm A of 0.65 at 5 years. This required 480 patients per arm and 250 events.
Final results are reported according to the standardized system for efficacy end
points (STEEP system).
Between July 1998 and July 2002, 972 patients were randomized (486 in
each arm). At a median follow-up of 62 months, 278 IDFS events were
recorded. Five-year IDFS was 74% in arm B vs 68% in arm A (P = 0.13), with
a hazard ratio (HR) of 0.82 (95% confidence interval [CI] = 0.64–1.03). RFS
was significantly better for arm B than for arm A (76% vs 69%; P = 0.0332)
with a HR of 0.75 (95% CI = 0.59–0.96). There was a significant improvement
in OS, with an estimated five-year OS of 90% in arm B and 85% in arm A (P =
0.0168; HR = 0.67, 95% CI = 0.48–0.94). This benefit comes at the cost of
increased but acceptable toxicity.
We demonstrated, with the results of the Taxit 216 phase III trial, that
incorporating docetaxel into a block-sequential epirubicin–CMF regimen
significantly reduces the risk of recurrence and death in patients with nodepositive
ESBC.

description: By solving the kinetic spin Bloch equations, we study the time evolution of the transient spin grating, whose spin polarization varies periodically in real space, confined in (001) GaAs quantum wells. With this study we can investigate the properties of both the spin transport and the spin relaxation at the same time. The Fourier component of the spin signal decays double exponentially with two decay rates $1/τ_+$ and $1/τ_-$. In high temperature regime, the average of these two rates varies with the grating wave-vector $q$ quadratically, i.e., $(1/τ_++1/τ_-)/2=D_sq^2+1/\tildeτ_s$, with $D_s$ and $\tildeτ_s$ representing the spin diffusion coefficient and the average of the out-of-plane and the in-plane spin relaxation times respectively. $τ_{\pm}$ calculated from our theory are in good agreement with the experimental data by Weber {\em et al.} [Phys. Rev. Lett. {\bf 98}, 076604 (2007)]. By comparing $D_s$ with and without the electron-electron Coulomb scattering, we calculate the contribution of Coulomb drag to the spin diffusion coefficient. With the transient spin grating result, we further reveal the relations among different characteristic parameters such as spin diffusion coefficient $D_s$, spin relaxation time $τ_s$, and spin injection length $L_s$. We show that in the presence of the Dresselhaus and/or Rashba spin-orbit coupling, the widely used relation $L_s=\sqrt{D_sτ_s}$ is generally inaccurate and can even be very wrong in some special cases. We present an accurate way to extract the steady-state transport characteristic parameters from the transient spin grating signals.

description: Whereas electron-phonon scattering typically relaxes the electron's momentum in metals, a perpetual exchange of momentum between phonons and electrons conserves total momentum and can lead to a coupled electron-phonon liquid with unique transport properties. This theoretical idea was proposed decades ago and has been revisited recently, but the experimental signatures of an electron-phonon liquid have been rarely reported. We present evidence of such a behavior in a transition metal ditetrelide, NbGe$_2$, from three different experiments. First, quantum oscillations reveal an enhanced quasiparticle mass, which is unexpected in NbGe$_2$ due to weak electron-electron correlations, hence pointing at electron-phonon interactions. Second, resistivity measurements exhibit a discrepancy between the experimental data and calculated curves within a standard Fermi liquid theory. Third, Raman scattering shows anomalous temperature dependence of the phonon linewidths which fits an empirical model based on phonon-electron coupling. We discuss structural factors, such as chiral symmetry, short metallic bonds, and a low-symmetry coordination environment as potential sources of coupled electron-phonon liquids.

Aneuploidie in spermatozoi ed ovociti maturati in vitro in bovini di razza Frisona Italiana e Bruna italiana mediante microdissezione cromosomica e ibridazione fluorescente in situ (FISH)

description: Le aneuploidie sono responsabili di sbilanciamenti genetici che impediscono il normale processo di sviluppo dell’embrione e sono tra le cause principali di mortalità embrionale e fetale. Negli animali domestici esiste una quasi totale mancanza di dati rispetto all’incidenza di aneuploidie nelle cellule germinali, nonostante l’importanza che queste rivestono sia dal punto di vista zootecnico, in quanto causa di riduzione della fertilità, sia dal punto di vista biomedico, come modello da cui derivare informazioni utili nella ricerca applicata all’uomo.
Sempre più studi hanno messo in luce la relazione che esiste tra ambiente di vita (esposizione ad inquinanti, fitofarmaci, molecole tossiche) e incidenza di anomalie cromosomiche nelle cellule germinali e gli animali domestici sono sempre più frequentemente esposti a molecole inquinanti attraverso l’alimentazione e l’ambiente di allevamento. Per tali ragioni è fondamentale conoscere l’incidenza di base di aneuploidie nelle cellule germinali, al fine di programmare indagini volte ad identificare e rimuovere possibili cause di riduzione della fertilità. A tal fine è stata sviluppata una metodica di ibridazione fluorescente in situ utilizzando sonde ‘painting’ cromosoma-specifiche prodotte tramite microdissezione cromosomica e DOP-PCR per investigare l’assetto cromosomico di spermatozoi (cromosomi X e Y) ed ovociti (cromosomi X e 5) in due delle principali razzi da latte, la Frisona Italiana e la Bruna Italiana. L’incidenza media di aneuploidie e diploidie negli spermatozoi è stata dello 0.110% e 0.050% nella Frisona e dello 0.078% e 0.062% nella Bruna. Gli ovociti diploidi sono stati complessivamente il 14.4% (11.2% nella Frisona e 18.4% nella Bruna) e gli aneuploidi il 2.2% (2% nella Frisona e 2.5% nella Bruna). Gli ovociti sembrano quindi essere maggiormente soggetti ad eventi di non-disgiunzione; ulteriori studi sono necessari, in vivo, per chiarire gli effetti del sistema di coltivazione in vitro sulla frequenza di anomalie cromosomiche.
Functions of the Krüppel-like Factor 7 protein in cellular differentiation and neuronal morphogenesis

description: KLF7 is a transcription factor that is expressed during embryogenesis mostly in the nervous system and its inactivation in mice leads to perinatal lethality associated with multiple neuronal defects. To identify KLF7 functions I have used an in vitro approach performed on PC12, primary and embryonic stem (ES) cells in order to elucidate KLF7 role in differentiation processes. Subsequently I have investigated KLF7 role during mouse embryogenesis using Klf7 null mice. The major finding in all the in vitro experiments was that KLF7 depletion both by RNA interference (RNAi) and gene deletion alters the appropriate differentiation mechanisms in neurogenic, cardiogenic, adipogenic and osteogenic processes. Moreover I have analysed the KLF7 potential role in ES cells self-renewal pathways and I have found by RNAi that Oct4 or Nanog increase Klf7 gene expression.
In the course of the in vivo experiments I have analysed Klf7 expression during wt brain ontogenesis and found a sharp peak concomitant with development of dopaminergic system in the midbrain. Thus the transcriptional characterization of the Klf7-KO mouse brain suggested a dopaminergic deficit in Klf7-KO mice. Indeed the newborn mutant analysed showed a significant decrease in Tyrosine Hydroxylase (Th) and Dopamine Transporter (Dat) mRNA both in the ventral midbrain and olfactory bulbs (OB). TH and DAT are specific markers of the dopaminergic function. In accordance with the biochemical data, immunohistochemical analysis showed reduction of TH positive fibres in the striatum and TH positive neurons in the midbrain and OB.
To further evaluate the Klf7 function in the central nervous system development, I have compared self-renewal and neuronal differentiation ability of wt and Klf7-KO derived neurospheres. To this aim I have used counting of cells positive for BLBP and western blot analysis. Both revealed a deficit in this neural stem cells marker in the Klf7-KO neurospheres.
Altogether the results of this work support the hypothesis that KLF7 plays a wide role in cellular differentiation and in a number of developmental pathways. Among these a potential role for KLF7 in the maintenance of the dopaminergic phenotype emerges.

description: The set of solutions of random constraint satisfaction problems (zero energy groundstates of mean-field diluted spin glasses) undergoes several structural phase transitions as the amount of constraints is increased. This set first breaks down into a large number of well separated clusters. At the freezing transition, which is in general distinct from the clustering one, some variables (spins) take the same value in all solutions of a given cluster. In this paper we study the critical behavior around the freezing transition, which appears in the unfrozen phase as the divergence of the sizes of the rearrangements induced in response to the modification of a variable. The formalism is developed on generic constraint satisfaction problems and applied in particular to the random satisfiability of boolean formulas and to the coloring of random graphs. The computation is first performed in random tree ensembles, for which we underline a connection with percolation models and with the reconstruction problem of information theory. The validity of these results for the original random ensembles is then discussed in the framework of the cavity method.

description: L'istituto della rimessione in termini permette alla parte incorsa in una decadenza per una causa non imputabile di compiere l'attività dalla quale era decaduta. La disciplina dell'istituto ha subito diverse modifiche: inizialmente disciplinato all'art. 184-bis c.p.c., relativo alle sole decadenze interne, con la legge n. 69 del 2009 è stato spostato all'art. 153, comma 2°, c.p.c. Tale modifica sottolinea l'avvenuta generalizzazione dell'istituto della rimessione in termini: ciò ha inciso anche sull'ambito di applicazione. Si ritiene, infatti, che oggi sia applicabile anche alle decadenze dai poteri esterni ed ai processi diversi da quello a cognizione piena.

description: Boolean delay equations (BDEs), with their relatively simple and intuitive mode of modelling, have been used in many research areas including, for example, climate dynamics and earthquake propagation. Their application to biological systems has been scarce and limited to the molecular level. Here, we derive and present two BDE models. One is directly derived from a previously published ordinary differential equation (ODE) model for the bovine estrous cycle, whereas the second model includes a modification of a particular biological mechanism. We not only compare the simulation results from the BDE models with the trajectories of the ODE model, but also validate the BDE models with two additional numerical experiments. One experiment induces a switch in the oscillatory pattern upon changes in the model parameters, and the other simulates the administration of a hormone that is known to shift the estrous cycle in time. The models presented here are the first BDE models for hormonal oscillators, and the first BDE models for drug administration. Even though automatic parameter estimation still remains challenging, our results support the role of BDEs as a framework for the systematic modelling of complex biological oscillators.
