description: Η ανάπτυξη των νέων τεχνολογιών που έχουν προκύψει από τα μέσα της δεκαετίας του 1990 οδήγησε σε εφαρμογές βασισμένες στο διαδίκτυο γνωστές ως «κοινωνικά μέσα» που επιτρέπουν στους ανθρώπους να αλληλεπιδρούν και να έχουν πρόσβαση σε πληροφορίες. Στην παρούσα εργασία εξετάζεται πως οι οργανισμοί έκτακτης ανάγκης χρησιμοποιούν τις διαθέσιμες τεχνολογίες των κοινωνικών μέσων για την αντιμετώπιση μιας κρίσης. Σκοπός της παρούσης εργασίας είναι να διερευνηθεί αν τα κοινωνικά μέσα μπορούν να χρησιμοποιηθούν και να γίνουν αποδεκτά ως πιθανά εργαλεία που επιτρέπουν σε άτομα και οργανώσεις να συνεργαστούν με αμοιβαία επωφελείς τρόπους, σε όλα τα στάδια της διαχείρισης καταστάσεων έκτακτης ανάγκης: μετριασμός, ετοιμότητα, αντιμετώπιση.
 Η έρευνα βασίζεται σε βιβλιογραφική επισκόπηση και εμπειρική μελέτη περιπτώσεων στα πλέον γνωστά κοινωνικά δίκτυα όπως το Facebook, twitter, youtube κ.τ.λ.
 Οι συνδεμένοι ιστότοποι κοινωνικής δικτύωσης γίνονται εξαιρετικά δημοφιλείς και μπορούν να χρησιμοποιηθούν σε μια ποικιλία από περιβάλλοντα και κατά πολλούς ερευνητές μπορούν σε καταστάσεις έκτακτης ανάγκης να προφέρουν μια λύση ως “on – stop shop”.
 Τα αποτελέσματα αυτής της αναγνωριστικής έρευνας δείχνουν ότι οι συνδεμένοι ιστότοποι κοινωνικής δικτύωσης θα πρέπει να θεωρούνται βιώσιμη λύση στα προβλήματα που μαστίζουν τη διάδοση των πληροφοριών και των επικοινωνιών στον τομέα έκτακτης ανάγκης. Ερευνητικά θέματα προκύπτουν στους τομείς της πρόσβασης στα δεδομένα, την ποιότητα των δεδομένων, τη σύνθεση των πληροφοριών, αναδυόμενα πρότυπα της ανθρώπινης συμπεριφοράς σε καταστάσεις έκτακτης ανάγκης, προστασία της ιδιωτικής ζωής κτλ.
QUALIFICATION OF LOW DOSE HYDRATE INHIBITORS (LDHIS): FIELD CASES STUDIES DEMONSTRATE THE GOOD REPRODUCIBILITY OF THE RESULTS OBTAINED FROM FLOW LOOPS

description: Replacement of the traditional thermodynamic hydrate inhibitors (methanol and glycols) in multiphase applications is highly desirable for Health, Safety & Environment (HSE) considerations and for investment costs savings. Low Dose Hydrate Inhibitors (LDHI) are good candidates to achieve this objective and their interest is growing in the E&P industry. There are two types of LDHI: the Kinetic Hydrate Inhibitors (KHI) and the Anti-Agglomerants (AA) also called dispersant additives. The main challenge with LDHIs is that they require the unprocessed effluents to be produced inside the hydrate stability zone. It is then of the utmost importance to select, qualify and implement properly LDHIs, so that their field deployment is performed with success. But due to the very stochastic nature of the nucleation step, the hydrate crystallisation process leads to very large discrepancies between performances results carried out at lab or pilot scales. In order to overcome this difficulty, we have developed an in-house special protocol which is implemented prior to each qualification tests series. This in-house 15 years old protocol consists in conducting each tests series with a fluids system having previously formed hydrates in a first step but followed by a dissociation step at moderate temperature for a few hours. This paper presents results selected from several field cases studies and obtained from our 80 bara and 165 bara flow loops. They show the very good reproducibility obtained with and without LDHIs. In the case of KHI, where the stochastic nature of the nucleation step is very critical, the results show that the deviation on the “hold time” for a given subcooling is less than 15%.

description: Fluoxetine is a Selective Serotonin Reuptake Inhibitor (SSRI) often prescribed for the treatment of anxiety and depression. Many of its effects are thought to be mediated by the dentate gyrus, but the mechanism by which some patients respond to treatment and some do not remains poorly understood. In this study we have characterized a previously-unknown component of the behavioral response to fluoxetine in the dentate gyrus, using a combination of genomic, behavioral, and imaging techniques. We have found that different components of the opioid system are involved in the treatment efficacy of fluoxetine in the dentate gyrus. Specifically, we have identified a population of anatomically and transcriptionally distinct mature granule cells that are defined by their high levels of proenkephalin expression after fluoxetine treatment. Furthermore, we have shown that the delta opioid receptor is partly mediating some of the behavioral effects of fluoxetine in a neurogenesis-independent manner. These results open an interesting new avenue for research into the involvement of the opioid system in the behavioral response to SSRIs.

description: We apply a fully automated extension of the $R^*$-operation capable of calculating higher-loop anomalous dimensions of n-point Green's functions of arbitrary, possibly non-renormalisable, local Quantum Field Theories. We focus on the case of the CP-violating Weinberg operator of the Standard Model Effective Field Theory whose anomalous dimension is so far known only at one loop. We calculate the two-loop anomalous dimension in full QCD and the three-loop anomalous dimensions in the limit of pure Yang-Mills theory. We find sizeable two-loop and large three-loop corrections, due to the appearance of a new quartic group invariant. We discuss phenomenological implications for electric dipole moments and future applications of the method.

After introducing a regularization prescription that entails the consideration of framed knots, we present the general form of the vacuum expectation value of a Wilson loop. The resulting expression turns out to give the same framing dependence as the one obtained using non-perturbative methods and perturbative methods in covariant gauges. It also contains the Kontsevich integral for Vassiliev invariants of framed knots.

description: I tested the effects of contingent auditory feedback on the elimination of stereotypy in a delayed non-concurrent multiple probe design with multiple treatment reversals, counterbalanced across 2 male elementary school students with autism spectrum disorders (ASD) in Experiment I. My findings supported evidence for the effectiveness of contingent addition or removal of auditory stimuli (Hugh-Pennie, 2006) in reducing the frequency levels of stereotypy and increasing self-awareness of one's own stereotypic behaviors. In addition, generalization effects were demonstrated as a result of the shift of the discriminative stimulus (SD) from the presentation of the auditory feedback device to the presence of the experimenter. Thus, the stimulus control of a verbal audience in one setting (with a direct intervention) transferred to another setting (i.e., the instructional periods) without a direct auditory feedback intervention. However, during the 3-month follow-up probes, both participants' frequency levels of stereotypy returned to the initial levels. As an extended test of auditory feedback, Experiment II used a within-subjects delayed non-concurrent multiple probe design with multiple treatments across 4 participants, who had audience control, to test the effects of contingent auditory feedback on the elimination of stereotypy and the emission of socially appropriate verbal exchanges (i.e., conversational units) during academic, lunch, and recess periods in the mainstream general education settings in the presence of typically developing peers. All participants were diagnosed with ASD and attended a combined 3rd to 5th grade self-contained special education classroom in a public elementary school. The results of Experiment II showed a functional relation between the implementation of auditory feedback procedure in mainstream general education settings and the increased emission and initiation of socially appropriate verbal exchanges by both the typically developing peers and the participants as the participants' emission of stereotypy decreased. In addition, generalization effects were demonstrated in the self-contained special education settings in the absence of typically developing peers without a direct intervention (i.e., all participants' emission of stereotypy decreased while their initiation of conversational units with peers increased).

description: We investigate stationary charge imbalance effect in the system of coupled overdamped Josephson junctions. We show that coupling between junction and nonzero stationary charge imbalance in the resistive state bring to a decrease of the Josephson frequency in the Josephson junctions of the stack. The formed difference in Josephson frequency leads to the nonuniform switch to the Shapiro step regime in the presence of external electromagnetic radiation and appearance of kinks of voltage on the IV-characteristics of the stack. We also show that stationary charge imbalance brings to the slope of the Shapiro step due to the difference of the charge imbalance potential on the edges of the step. The theoretical and experimental results for voltage bias coupled Josephson junctions have been compared with the current bias case.
Effects of the Mental Health Practitioner's Professional Affiliation, Gender, and Warmth on Client Attitude Change

description: This study tested the effects of a mental health practitioner's professional affiliation (psychiatry, clinical psychology, and social work), gender, and warmth on clients' perceptions of the professional's expertness and social attractiveness and the relationship between these perceptions and the influence the mental health practitioner has on client attitude change. Using social psychology's literature on attitude change as a frame of reference, the study was based on the premise that social work practice is a process of social influence in which the social worker attempts to influence clients to change their attitudes.

The subjects were 120 randomly selected male inpatients from an alcohol detoxification unit at a private hospital in New York City. They were randomly assigned to one of twelve experimental conditions based on the mental health practitioner's professional affiliation, gender, and the description of the practitioner as a warm or cold person. These experimental conditions were established by biographical sketches describing the mental health professional. The subjects then listened to a ten-minute segment of a simulated psychotherapy session and completed the Counselor Rating Form which measured the subjects' perceptions of the mental health practitioner's expertness and attractiveness, and the Persuasibility Questionnaire, which measured the tape mental health professional's influence on subjects' attitudes.

The results indicated that the practitioners from all three professions were perceived to be equally expert and attractive as were the male and female practitioners in both psychiatry and psychology. Although male and female social workers were perceived to be equally attractive, the male social workers were perceived to be significantly more expert than their female counterparts. When the psychiatrists and psychologists were described as warm they were perceived to be significantly more expert and attractive than when they were described as cold. However, the description of the social worker as warm had no differential effect on the subjects' perceptions. This resulted from the subjects' failure to see the social workers as cold, even when they were so described.

The overall findings of this study indicated that the more expert and attractive mental health professionals were perceived to be, the more influence they had in changing the subjects' attitudes. This held true for all subgroups except social workers and male mental health professionals.

description: The formation of coherent multisensory percepts requires integration of stimuli across the multiple senses. Patients with schizophrenia (ScZ) often experience a loss of coherent perception and hence, they might also show dysfunctional multisensory processing. In this high-density electroencephalography study, we investigated the neural signatures of the McGurk illusion, as a phenomenon of speech-specific multisensory processing. In the McGurk illusion lip movements are paired with incongruent auditory syllables, which can induce a fused percept. In ScZ patients and healthy controls we compared neural oscillations and event-related potentials (ERPs) to congruent audiovisual speech stimuli and McGurk illusion trials, where a visual /ga/ and an auditory /pa/ was often perceived as /ka/. There were no significant group differences in illusion rates. The EEG data analysis revealed larger short latency ERPs to McGurk illusion compared with congruent trials in controls. The reversed effect pattern was found in ScZ patients, indicating an early audiovisual processing deficit. Moreover, we observed stronger suppression of medio-central alpha-band power (8–10 Hz, 550–700 ms) in response to McGurk illusion compared with control trials in the control group. Again, the reversed pattern was found in SCZ patients. Moreover, within groups, alpha-band suppression was negatively correlated with the McGurk illusion rate in ScZ patients, while the correlation tended to be positive in controls. The topography of alpha-band effects indicated an involvement of auditory and/or frontal structures. Our study suggests that short latency ERPs and long latency alpha-band oscillations reflect abnormal multisensory processing of the McGurk illusion in ScZ.
Optically and thermally induced molecular switching processes at metal surfaces

Subjects: subject: 500 Naturwissenschaften und Mathematik::530 Physik

description: Using light to control the switching of functional properties of surface-bound species is an attractive strategy for the development of new technologies with possible applications in molecular electronics and functional surfaces and interfaces. Molecular switches are promising systems for such a route, since they possess the ability to undergo reversible changes between different molecular states and accordingly molecular properties by excitation with light or other external stimuli. In this review, recent experiments on photo- and thermally induced molecular switching processes at noble metal surfaces utilizing two-photon photoemission and surface vibrational spectroscopies are reported. The investigated molecular switches can either undergo a trans–cis isomerization or a ring opening–closure reaction. Two approaches concerning the connection of the switches to the surface are applied: physisorbed switches, i.e. molecules in direct contact with the substrate, and surface- decoupled switches incorporated in self-assembled monolayers. Elementary processes in molecular switches at surfaces, such as excitation mechanisms in photoisomerization and kinetic parameters for thermally driven reactions, which are essential for a microscopic understanding of molecular switching at surfaces, are presented. This in turn is needed for designing an appropriate adsorbate–substrate system with the desired switchable functionality controlled by external stimuli.

description: It is well known that Artificial Neural Networks are universal approximators. The classical result proves that, given a continuous function on a compact set on an n-dimensional space, then there exists a one-hidden-layer feedforward network which approximates the function. Such result proves the existence, but it does not provide a method for finding it. In this paper, a constructive approach to the proof of this property is given for the case of two-hidden-layer feedforward networks. This approach is based on an approximation of continuous functions by simplicial maps. Once a triangulation of the space is given, a concrete architecture and set of weights can be obtained. The quality of the approximation depends on the refinement of the covering of the space by simplicial complexes.

description: We have carried out a submillimeter continuum and spectroscopic study of the W43 main complex, a massive star-forming region, which harbors a giant HII region. The maps reveal a filamentary structure containing ~50 fragments with masses of 40-4000 Msun and typical diameters of 0.25 pc. Their large sizes, large non-thermal velocities (Dv ~ 5 km/s), and high densities (n_H2 ~ 10^6 cm^-3) suggest that they are protoclusters and excellent sites to form massive stars. Follow-up observations are necessary, but we have already identified three protoclusters to be very good candidates for containing very young massive protostars. The starburst cluster, that excites the giant HII region has a large impact on the molecular complex. However, it remains unclear if this first episode of star formation is triggering the formation of new massive stars, through ionization shocks crossing the closeby molecular clouds. W43 is thus an ideal laboratory to investigate massive star formation from the protostellar phase to that of giant HII regions. Moreover, the very active star-forming complex W43 may be considered a Galactic mini-starburst region that could be used as a miniature model of starburst galaxies.

description: We assume that the gravitational instability of standard thin accretion disks leads to the Broad Line Regions (BLRs), the B band luminosity comes from standard thin disk and the motion of BLRs is virial. The central black hole masses, the accretion rates and the disk inclinations to the line of sight for 17 Seyfert 1 galaxies and 17 Palomar-Green (PG) quasars have been calculated. Our results are sensitive to $α$ parameter of the standard $α$ disk. With the same values of $α$ ($α=1$), calculated central black hole masses for 17 Seyfert 1 galaxies are consistent with that from Kaspi et al. (2000) while that for 17 PG quasars are larger than that from Kaspi et al. (2000) by almost 2 orders of magnitude. Inclinations of 17 Seyfert 1 galaxies are about 6 times larger than that of 17 PG quasars. These inclinations, with a mean value of $32^{o}$ for 17 Seyfert 1 galaxies that agrees well with the result obtained by fitting the iron $Kα$ lines of Seyfert 1 galaxies observed with ASCA (Nandra et al. 1997) and the result obtained by Wu & Han (2001), provide further support for the orientation-dependent unification scheme of active galactic nuclei. There is a relation between the FWHM of H$β$ and the inclination, namely the inclination is smaller in AGNs with smaller FWHM of H$β$. The effect of inclinations in narrow line Seyfert 1 galaxies (NLS1s) should be considered when one studies the physics of NLS1s. (abbreviated)

description: La construcción de identidades y de alteridad en el contexto histórico-social y político de América Latina no es un proceso inocuo, sino que constituye el punto de partida para generar y legitimar desigualdades. Para comprender cabalmente la exclusión, invisibilización, e intentos de homogenización o segregación cultural-racial-étnica es preciso ubicar estas problemáticas en el proceso que fue constitutivo de los mismos. La propuesta es abordar la noción de colonialidad y la distribución de identidades sociales racializadas como la matriz de poder que opera en la constitución y perpetuación de las desigualdades sociales. En este marco teórico, se abordará la noción de “diferencia colonial” de W. Mignolo, con la que se alude al proceso de escisión colonizador/colonizado, para luego complementarla con un análisis del racismo cultural, develando la continuidad entre la esencialización de las esferas de lo cultural y de lo racial. La idea que surge no desvanecer la noción de cultura o diversidad cultural, sino resignificarla.

We thus investigate Urca rates at different temperatures and field strengths by performing the full temperature and magnetic-field dependent rate integrals for different equations of state. We find that the magnetic fields play an important role at temperatures of a few MeV, especially close to or below the direct Urca threshold, which is softened by the magnetic field. At higher temperatures, the effect of the magnetic fields can be overshadowed by the thermal effects. We observe that the magnetic field more strongly influences the neutron decay rates than the electron capture rates, leading to a shift in the flavor equilibrium.

Efficacy of Home-based Intensive Bimanual Training for Children with Unilateral Spastic Cerebral Palsy
Creators: Ferre, Claudio Luis
Publisher: name: Columbia University
Year: 2015
Subjects: Kinesiology

description: Neuroplasticity research suggests intervention at early developmental stages is optimal for maximizing recovery of function in children with unilateral spastic cerebral palsy (USCP). Intensive bimanual training is an effective method for improving upper-extremity function in children with USCP when provided in massed-practice day camps. Given the challenges young children face sustaining attention and their susceptibility to fatigue, adapted models using distributed practice are required. The aim of this study was to perform a randomized trial comparing home-based hand-arm bimanual intensive training (H-HABIT) with a control group receiving an intervention of equal duration, intensity, and social interaction. Twenty-four children with USCP (age range 2 yr., 6 mos. - 10 yr. 1 mos.) were randomized to participate in either 90 hours of H-HABIT (n=12) or an equivalent dose of functional lower-limb training (FLL-control; n=12). Caregivers were trained by experienced interventionists to administer either H-HABIT or FLL-control. Caregivers then performed activities with children in their own home 2 hrs./day, 5 days/week for 9 weeks (90 hrs. total). Caregivers were supervised remotely once a week for one hour using telerehabilitation. Dexterity was assessed using the Box and Blocks test. Bimanual hand function was measured using the Assisting Hand Assessment (AHA). Canadian Occupational Performance Measure (COPM) was used to assess caregiver perception (performance and satisfaction) of functional goals. All measures were assessed immediately prior to (pretest) and immediately after (posttest) the intervention and analyzed with a 2(group) x 2(session) repeated measures ANOVA. There were no statistical differences between the two groups at baseline. Children in H-HABIT showed greater improvement (pretest=9.0±5.8; posttest=14.5±7.8) than children in FLL-control (pretest=10.6±7.2; posttest=11.9±6.1) on the Box and Blocks test (for interaction, F(1,20)=18.53, p.05) (H-HABIT=60.5 AHA units±10.1; FLL-Control=52.8 AHA units±17.1). COPM data revealed a significant test session by group interaction (F(1,22)=10.82, p

description: After Amdahl's trailblazing work, many other authors proposed analytical speedup models but none have considered the limiting effect of the memory wall. These models exploited aspects such as problem-size variation, memory size, communication overhead, and synchronization overhead, but data-access delays are assumed to be constant. Nevertheless, such delays can vary, for example, according to the number of cores used and the ratio between processor and memory frequencies. Given the large number of possible configurations of operating frequency and number of cores that current architectures can offer, suitable speedup models to describe such variations among these configurations are quite desirable for off-line or on-line scheduling decisions. This work proposes new parallel speedup models that account for variations of the average data-access delay to describe the limiting effect of the memory wall on parallel speedups. Analytical results indicate that the proposed modeling can capture the desired behavior while experimental hardware results validate the former. Additionally, we show that when accounting for parameters that reflect the intrinsic characteristics of the applications, such as degree of parallelism and susceptibility to the memory wall, our proposal has significant advantages over machine-learning-based modeling. Moreover, besides being black-box modeling, our experiments show that conventional machine-learning modeling needs about one order of magnitude more measurements to reach the same level of accuracy achieved in our modeling.

description: Purpose: The purpose of this study was to evaluate the efficacy of a newly adapted treatment, Attentive Reading with Constrained Summarization-Written, to improve microlinguistic and macrolinguistic aspects of written and spoken discourse of people with mild aphasia.
      Background: Attentive Reading with Constrained Summarization-Written takes a top-down approach to language rehabilitation that focuses on the cognitive-linguistic processes required for spoken and written discourse production.
      Methods: Five people with mild aphasia received Attentive Reading with Constrained Summarization-Written across two single subject experimentally controlled pre-post treatment design studies.
      Results: All participants demonstrated improvement in both written and spoken discourse generalization measures. Improvement in functional communication, and confrontation naming was also observed for some participants.
      Conclusions: The results reported in these two studies provide preliminary evidence that Attentive Reading with Constrained Summarization-Written is a viable treatment option to improve both written and spoken discourse in people with mild aphasia. Participants demonstrated different pre-treatment profiles and mechanisms of improvement, which are discussed.

Chiral charge dynamics in Abelian gauge theories at finite temperature

description: We study fermion number non-conservation (or chirality breaking) in Abelian gauge theories at finite temperature. We consider the presence of a chemical potential $μ$ for the fermionic charge, and monitor its evolution with real-time classical lattice simulations. This method accounts for short-scale fluctuations not included in the usual effective magneto-hydrodynamics (MHD) treatment. We observe a self-similar decay of the chemical potential, accompanied by an inverse cascade process in the gauge field that leads to a production of long-range helical magnetic fields. We also study the chiral charge dynamics in the presence of an external magnetic field $B$, and extract its decay rate $Γ_5 \equiv -{d\log μ\over dt}$. We provide in this way a new determination of the gauge coupling and magnetic field dependence of the chiral rate, which exhibits a best fit scaling as $Γ_5 \propto e^{11/2}B^2$. We confirm numerically the fluctuation-dissipation relation between $Γ_5$ and $Γ_{\rm diff}$, the Chern-Simons diffusion rate, which was obtained in a previous study. Remarkably, even though we are outside the MHD range of validity, the dynamics observed are in qualitative agreement with MHD predictions. The magnitude of the chiral/diffusion rate is however a factor $\sim 10$ times larger than expected in MHD, signaling that we are in reality exploring a different regime accounting for short scale fluctuations. This discrepancy calls for a revision of the implications of fermion number and chirality non-conservation in finite temperature Abelian gauge theories, though not definite conclusion can be made at this point until hard-thermal-loops (HTL) are included in the lattice simulations.

A weight-adjusted discontinuous Galerkin method for wave propagation in coupled elastic-acoustic media

description: This paper presents a high-order discontinuous Galerkin (DG) scheme for the simulation of wave propagation through coupled elastic-acoustic media. We use a first-order stress-velocity formulation, and derive a simple upwind-like numerical flux which weakly imposes continuity of the normal velocity and traction at elastic-acoustic interfaces. When combined with easily invertible weight-adjusted mass matrices, the resulting method is efficient, consistent, and energy stable on curvilinear meshes and for arbitrary heterogeneous media, including anisotropy and sub-cell (micro) heterogeneities. We numerically verify the high order accuracy and stability of the proposed method, and investigate its performance for applications in photoacoustic tomography.
