description: Despite over three hundred years of effort, no solutions exist for predicting when a general planetary configuration will become unstable. We introduce a deep learning architecture to push forward this problem for compact systems. While current machine learning algorithms in this area rely on scientist-derived instability metrics, our new technique learns its own metrics from scratch, enabled by a novel internal structure inspired from dynamics theory. Our Bayesian neural network model can accurately predict not only if, but also when a compact planetary system with three or more planets will go unstable. Our model, trained directly from short N-body time series of raw orbital elements, is more than two orders of magnitude more accurate at predicting instability times than analytical estimators, while also reducing the bias of existing machine learning algorithms by nearly a factor of three. Despite being trained on compact resonant and near-resonant three-planet configurations, the model demonstrates robust generalization to both non-resonant and higher multiplicity configurations, in the latter case outperforming models fit to that specific set of integrations. The model computes instability estimates up to five orders of magnitude faster than a numerical integrator, and unlike previous efforts provides confidence intervals on its predictions. Our inference model is publicly available in the SPOCK package, with training code open-sourced.

description: Η διπλωματική εργασία έχει θέμα τον Θεατρικό Οργανισμό «Νέες Μορφές» και στόχο της την ιστορική καταγραφή της οκτάχρονης πορείας του (1997-2004). Ως γενικό πλαίσιο μπορεί να σημειωθεί το χαρακτηριστικό αποτύπωμα της θεατρικής τέχνης και της καλλιτεχνικής έκφρασης που άφησε η ομάδα των «Νέων Μορφών» στη θεατρική παραγωγή της πόλης της Θεσσαλονίκης. Η εργασία έχει ως αφετηρία την παραστασιογραφία των «Νέων Μορφών». Ωστόσο η αντικειμενική καταγραφή, που θα αποστασιοποιείται από τα προσωπικά βιώματα με τη διπλή μου ιδιότητα (ιδρυτικό στέλεχος και σκηνογράφος-ενδυματολόγος) των «Νέων Μορφών», δεν ήταν εύκολη. Παρόλα αυτά το κίνητρο παρέμενε δυνατό λόγω της μαρτυρίας και της οπτικής μου ως ανθρώπου, ο οποίος ήταν παρών στη λειτουργία του θιάσου, του προσωπικού μου ενδιαφέροντος για την καταγραφή της πορείας ενός από τους πλέον ιστορικούς Θεατρικούς Οργανισμούς της Θεσσαλονίκης τα τελευταία 20 χρόνια και τέλος η καταγραφή να πραγματοποιηθεί, ενώ ιδρυτές και βασικοί συνεργάτες είναι ακόμα εν ζωή και μάλιστα θεατρικά ενεργοί. Η ύπαρξη οπτικού (φωτογραφικού, βιντεοσκοπημένου) και γραπτού υλικού από το αρχείο του Θεατρικού Οργανισμού, η μη ύπαρξη βιβλιογραφίας αλλά και η διάθεση της ακαδημαϊκής επιτροπής για την εκπόνηση μιας τέτοιας διπλωματικής εργασίας ήταν οι κινητήριες δυνάμεις για την καταγραφή του υπάρχοντος υλικού.
description: The topic of the present thesis is the Theatrical Agency "Nees Morfes" and the objective historical record of his eight-year course (1997-2004). As a general framework can be noted the characteristic footprint of theatrical art and artistic expression that the team of "Nees Morfes" left in the theatrical production to the city of Thessaloniki. As a starting point of thesis can be noted the recording performances of "Nees Morfes". However, the objective recording that has distanced itself from personal experiences combined with my dual capacity (founding member and set-costume designer) of "Nees Morfes", was not easy. Yet the motive remained powerful due to my testimony and view as a person, who was present at the operation of troupe, my personal interest in a track log of the most historic theater organizations of Thessaloniki in the last 20 years and finally the recording to take place, while founders and key partners are still alive and theatrical active. The existence of visual (photos, videos) and written material from the archives of the Theatrical Agency, the lack of literature and the availability of the academic committee for the preparation of such a thesis were the driving forces for the recording of existing equipment.

description: Counterstreaming plasma structures are widely present in laboratory experiments and astrophysical systems, and they are investigated either to prevent unstable modes arising in beam-plasma experiments or to prove the existence of large scale magnetic fields in astrophysical objects. Filamentation instability arises in a counterstreaming plasma and is responsible for the magnetization of the plasma. Filamentationally unstable mode is described by assuming that each of the counterstreaming plasmas has an isotropic Lorentzian (kappa) distribution. In this case, the filamentation instability growth rate can reach a maximum value markedly larger than that for a a plasma with a Maxwellian distribution function. This behaviour is opposite to what was observed for the Weibel instability growth rate in a bi-kappa plasma, which is always smaller than that obtained for a bi-Maxwellian plasma. The approach is further generalized for a counterstreaming plasma with a bi-kappa temperature anisotropy. In this case, the filamentation instability growth rate is enhanced by the Weibel effect when the plasma is hotter in the streaming direction, and the growth rate becomes even larger. These effects improve significantly the efficiency of the magnetic field generation, and provide further support for the potential role of the Weibel-type instabilities in the fast magnetization scenarios.

description: Previous studies have shown that the orientation relationships which develop in hetero-epitaxy are strongly influenced by the alignment of steps in the deposit with the pre-existing steps of the substrate. In this paper we use a combination of experiments with computer simulations to identify the important influence of substrate step structure on the eventual orientation relationships that develop in the deposit. We have made use of Ag deposited on Ni as it has been used extensively as a model system for the study of hetero-epitaxy. This system displays a large lattice mismatch of 16%. It is shown that on any surface vicinal to Ni(111), which has two possible kinds of <110> steps (A-steps with {100} ledges and B-steps with {111} ledges), a Ag deposit adopts a single orientation relationship because only A-steps remain stable in the presence of Ag.

description: We present a weak gravitational lensing analysis of 22 early-type strong lens galaxies, based on deep HST images obtained as part of the Sloan Lens ACS Survey. Using the most advanced techniques to control systematic uncertainties related to the variable PSF and charge transfer efficiency of the ACS, we detect weak lensing signal out to 300 kpc/h. We analyze blank control fields from the COSMOS survey in the same manner, inferring that the residual systematic uncertainty in the tangential shear is <0.3%. A joint strong and weak lensing analysis shows that the average total mass density profile is consistent with isothermal over two decades in radius (3-300 kpc/h, approximately 1-100 Reff). This finding extends by over an order of magnitude in radius previous results, based on strong lensing and/or stellar dynamics, that luminous and dark component ``conspire'' to form an isothermal mass distribution. In order to disentangle the contributions of luminous and dark matter, we fit a two-component mass model (R^1/4 + NFW) to the weak and strong lensing constraints. It provides a good fit to the data with only two free parameters; i) the average stellar mass-to-light ratio M_*/L_V=4.48 +- 0.46 hMo/Lo, in agreement with that expected for an old stellar population; ii) the average virial mass-to-light ratio M_vir/L_V = 246+101-87 hMo/Lo.

description: Internal friction in oxide thin films imposes a critical limitation to the sensitivity and stability of ultra-high finesse optical cavities for gravitational wave detectors. Strategies like doping or creating nanolaminates are sought to introduce structural modifications that reduce internal friction. This work describes an investigation of the morphological changes SiO2/Ta2O5 and TiO2/Ta2O5 nanolaminates undergo with annealing and their impact on room temperature internal friction. It is demonstrated that thermal treatment results in a reduction of internal friction in both nanolaminates, but through different pathways. In the SiO2/Ta2O5 nanolaminate, which layers remain intact after annealing, the total reduction in internal friction follows the reduction in the composing SiO2 and Ta2O5 layers. Instead, interdiffusion initiated by annealing at the interface of the TiO2/Ta2O5 nanolaminate and the formation of a mixed phase dictate a more significant reduction in internal friction to ~ 2.6 * 10-4, a value lower than any other Ta2O5 mixture coating with similar cation concentration.
Bounds on action of local quantum channels

description: We derive an upper bound on the action of a direct product of two quantum maps (channels) acting on multi-partite quantum states. We assume that the individual channels $Λ_j$ affect single-particle states so, that for an arbitrary input $ρ_j$, the distance $D_j (Λ_j [ ρ_j ], ρ_j)$ between the input $ρ_j$ and the output $Λ_j [ ρ_j ]$ of the channel is less than $ε$. Given this assumption we show that for an arbitrary {\em separable} two-partite state $ρ_{12}$ the distance between the input $ρ_{12}$ and the output $Λ_1\otimesΛ_2[ρ_{12} ]$ fulfills the bound $D_{12} (Λ_1 \otimes Λ_2 [ ρ_{12} ], ρ_{12}) \leq \sqrt{2+ 2 \sqrt{(1-1/d_1)(1-1/d_2)}} ε$ where $d_1$ and $d_2$ are dimensions of first and second quantum system respectively. On the contrary, entangled states are transformed in such a way, that the bound on the action of the local channels is $D_{12} (Λ_1 \otimes Λ_2 [ ρ_{12} ], ρ_{12}) \leq 2 \sqrt{2 - 1/d} \: ε$, where $d$ is the dimension of the smaller of the two quantum systems passing through the channels. Our results show that the fundamental distinction between the set of separable and the set of entangled states results into two different bounds which in turn can be exploited for a discrimination between the two sets of states. We generalize our results to multi-partite channels.

Ως ψυχοκοινωνικές μεταβλητές ορίστηκαν διαστάσεις της συναισθηματικής νοημοσύνης και συγκεκριμένα η αυτοεκτίμηση, η αυτοαντίληψη, η διαχείριση συναισθημάτων, η ενσυναίσθηση και οι διαπροσωπικές σχέσεις. Χρησιμοποιήθηκε ο παραδοσιακός χορός, ως μέσο παρέμβασης, για τη διερεύνηση της επίδρασης του στις προαναφερθείσες μεταβλητές. Στο πρόγραμμα συμμετείχαν ογδόντα μαθητές και μαθήτριες πρώτης τάξης δημοτικού σχολείου που δεν είχαν προηγούμενη εμπειρία σχετική με τον παραδοσιακό χορό. Στο πρόγραμμα παρέμβασης που διήρκησε δέκα εβδομάδες πραγματοποιήθηκαν δέκα συνεδρίες διάρκειας εξήντα λεπτών η καθεμία. Περιλάμβανε εκμάθηση ελληνικών παραδοσιακών χορών, ρυθμική αγωγή και διαθεματικές δραστηριότητες. Τα αποτελέσματα της έρευνας κατέδειξαν στατιστικά σημαντική αύξηση και στις τέσσερεις μεταβλητές στα παιδιά της πειραματικής ομάδας με μεγαλύτερο ποσοστό στην μεταβλητή της ενσυναίσθησης.
description: This research examined the effect of an intervention program of Greek traditional dances on psychosocial variables concerning seven year old students. The psychosocial variables were defined as dimensions of emotional intelligence, namely self-esteem, emotional management, empathy and interpersonal relationships. We used the traditional dance, as an intervention means to investigate the effect of the aforementioned variables. The program involved eighty students of primary education school who had no previous experience relevant to the traditional dance. The intervention program lasted ten weeks with a total of ten sessions lasted sixty minutes each and involved learning and practicing traditional Greek dances, rhythmic education and interdisciplinary activities. The results showed a significant increase on all emotional intelligence variables tested in the experimental group especially on the variable of empathy.

description: A systematic study of $γ$-bands observed in atomic nuclei is performed using the triaxial projected shell model (TPSM) approach. The staggering phase between the even and odd spin members of the $γ$-band for most the nuclei investigated in the present work is found to have even-I-below-odd-I, which in the framework of the collective model is considered as a signature of $γ$-softness. It is observed that out of twenty-three systems studied, only four nuclei, namely, $^{76}$Ge, $^{112}$Ru, $^{170}$Er and $^{232}$Th depict staggering phase with odd-I-below-even-I, which is regarded as an indication of the static $γ$-deformation in the collective model picture. The inclusion of the quasiparticle excitations in the framework of configuration mixing is shown to reverse the staggering phase from odd-I-down to the even-I-down for all the studied nuclei, except for the aforementioned four nuclei. Furthermore, by fitting a collective Bohr Hamiltonian to the TPSM energies, the differences between the two models are delineated through a comparison of the transition probabilities.

description: We report the detection of six discrete, low-luminosity (Lx < 10^33 erg/s) X-ray sources, located within 12 arcsec of the center of the collapsed-core globular cluster M30 (NGC 7099), and a total of 13 sources within the half-mass radius, from a 50 ksec Chandra ACIS-S exposure. Three sources lie within the very small upper limit of 1.9 arcsec on the core radius. The brightest of the three core sources has a luminosity of Lx (0.5-6 keV) = 6x10^32 erg/s and a blackbody-like soft X-ray spectrum, which are both consistent with it being a quiescent low-mass X-ray binary (qLMXB). We have identified optical counterparts to four of the six central sources and a number of the outlying sources, using deep Hubble Space Telescope and ground-based imaging. While the two proposed counterparts that lie within the core may represent chance superpositions, the two identified central sources that lie outside of the core have X-ray and optical properties consistent with being CVs. Two additional sources outside of the core have possible active binary counterparts. We discuss the X-ray source population of M30 in light of its collapsed-core status.

description: Training robust supervised deep learning models for many geospatial applications of computer vision is difficult due to dearth of class-balanced and diverse training data. Conversely, obtaining enough training data for many applications is financially prohibitive or may be infeasible, especially when the application involves modeling rare or extreme events. Synthetically generating data (and labels) using a generative model that can sample from a target distribution and exploit the multi-scale nature of images can be an inexpensive solution to address scarcity of labeled data. Towards this goal, we present a deep conditional generative model, called VAE-Info-cGAN, that combines a Variational Autoencoder (VAE) with a conditional Information Maximizing Generative Adversarial Network (InfoGAN), for synthesizing semantically rich images simultaneously conditioned on a pixel-level condition (PLC) and a macroscopic feature-level condition (FLC). Dimensionally, the PLC can only vary in the channel dimension from the synthesized image and is meant to be a task-specific input. The FLC is modeled as an attribute vector in the latent space of the generated image which controls the contributions of various characteristic attributes germane to the target distribution. An interpretation of the attribute vector to systematically generate synthetic images by varying a chosen binary macroscopic feature is explored. Experiments on a GPS trajectories dataset show that the proposed model can accurately generate various forms of spatio-temporal aggregates across different geographic locations while conditioned only on a raster representation of the road network. The primary intended application of the VAE-Info-cGAN is synthetic data (and label) generation for targeted data augmentation for computer vision-based modeling of problems relevant to geospatial analysis and remote sensing.

The experience of grief for surviving friends

Publisher: name: University of British Columbia
Year: 2009

description: The expanding body of literature in the field of bereavement has predominantly focused on the grief reactions of family members. The role of "bereaved", with its attendant grieving rights, has almost exclusively been accorded to the spouse and kin of the deceased. Despite the intimacy of the relationship often shared between the surviving close friend and the deceased, minimal research exists defining the experience of grief for these bereaved. Little is known about the meaning the bereaved friend bestows on his or her experience of grief. The purpose of this study is to explore the experience of grief in surviving friends. A phenomenological study based on unstructured interviews was undertaken to explore this experience with four adult women who have survived the death of a close friend. By making explicit the meanings implicit in their experience of grief, the meaning structure containing the essential elements of the phenomenon of grief for these bereaved friends was clarified . Ten elements or themes common to the experience of grief for all informants were illuminated and described. Implications for research and practice were also discussed.

description: We demonstrate that multiple-Higgs production at the LHC is the most sensitive probe of first and second-generation quark flavor in the Higgs sector. In models where new scalars couple to light quarks, gigantic di-Higgs and even sizable tri-Higgs production rates can be obtained, which can be used to either discover or severely constrain such theories. As an example, we show that the most stringent bounds on enhanced interactions of the $125\,\textrm{GeV}$ Higgs to the down quark in extended Higgs sectors are obtained by looking for the extra Higgs bosons that provide for such enhancements using the di-Higgs and $Zh$ topologies. In this context, we set new limits on the 125 GeV Higgs coupling to the down quark as strong as $λ_{hd\bar{d}} \lesssim 30 λ_{hd\bar{d}}^{\textrm{SM}}$ -- a dramatic improvement over previously available bounds. Regarding second-generation quark flavor, we obtain new limits in the coupling to strange as strong as $λ_{hs\bar{s}} \lesssim 10 λ_{hs\bar{s}}^{\textrm{SM}}$. In addition, we show that the currently unexplored triple-Higgs production topology could be a potential discovery channel of a wide variety of extended Higgs sectors at the LHC, including not only models where extra Higgses couple to light quarks, but also popular theories where they have preferential couplings to the the top.

description: In order to constrain the density of intermediate-mass black holes (IMBHs) in galaxies, we run smoothed particle hydrodynamics (SPH) simulations of a gas-rich disc dwarf galaxy, where different halo and disc populations of IMBHs are embedded. IMBHs, when passing through dense gas regions, can accrete gas and switch on as X-ray sources. We derive the luminosity distribution of simulated IMBHs, by assuming that they accrete at the Bondi-Hoyle rate. The X-ray distribution of simulated IMBHs has been compared with that of observed sources in the dwarf galaxy Holmberg II, chosen for its richness in gas, its small mass (compared to spiral galaxies), and the accuracy of the available X-ray measurements. Holmberg II also hosts one of the strongest IMBH candidates. From this comparison, we find that the density parameter of disc (halo) IMBHs must be

description: Aims. To study intensity oscillations in the solar chromosphere/corona above a quiet-Sun magnetic network. Methods. We analyse the time series of He II 256.32, Fe XI 188.23 and Fe XII 195.12 spectral lines observed by EUV Imaging Spectrometer (EIS) on board Hinode near the south pole. Then we use a standard wavelet tool to produce power spectra of intensity oscillations above the magnetic network. Results. We get ~7 min intensity oscillations in all spectral lines and ~13 min intensity oscillations only in He II with the probability of ~96-98 %, which probably reflects the process of magneto-acoustic wave propagation above the network. Conclusions. We suggest that field-free cavity areas under bipolar magnetic canopies in the vicinity of magnetic network may serve as resonators for the magneto-acoustic waves. The cavities with photospheric sound speed and granular dimensions may produce the waves with the observed periods. The waves may propagate upwards in the transition region/corona and cause observed intensity oscillations.

description: The Navier--Stokes order hydrodynamic equations for a low density granular mixture obtained previously from the Chapman--Enskog solution to the Boltzmann equation are considered further. The six transport coefficients associated with mass and heat flux in a binary mixture are given as functions of the mass ratio, size ratio, composition, and coefficients of restitution. Their quantitative variation across this parameter set is demonstrated using low order Sonine polynomial approximations to solve the exact integral equations. The results are also used to quantify the violation of the Onsager reciprocal relations for a granular mixture. Finally, the stability of the homogeneous cooling state is discussed.

Η ροή είναι ασυμπίεστη, ασταθής και δισδιάστατη. Ο αριθμός Reynolds που μελετάται στην παρούσα εργασία έχει τιμή Re=2800. Τα αριθμητικά αποτελέσματα, όπως οι στιγμιαίες γραμμές ροής και ταχύτητας παρουσιάζονται για το εσωτερικό και εξωτερικό περιβάλλον της κατασκευής. Από την ανάλυση των στιγμιαίων ταχυτήτων παρατηρήθηκαν έντονες μεταβολές στη διαμόρφωση της ροής ως προς το χρόνο.
description: The present work studies, numerically, the airflow inside and outside an agricultural structure with openings. The governing Navier-Stokes and continuity equations are solved with finite element method. The agricultural structure model is placed into a wind tunnel. The length of the structure model occupies the entire width of the wind tunnel. The flow is incompressible, unsteady and nominated to be two-dimensional. The Reynolds number studied in this work is Re=2800. The numerical results such as instantaneous streamlines and velocity values are presented for the interior and exterior environment of the structure. From the analysis of instantaneous velocities intense fluctuations were observed in the configuration of the flow in time.

description: This paper is devoted to theoretical and numerical investigation of the local minimum issue in seismic full waveform inversion (FWI). This paper provides a mathematical analysis of optimal transportation (OT) type objective function's differentiability and proves that the gradient obtained in the adjoint-state method does not depend on the particular choice of the Kantorovich potentials. A novel approach using the softplus encoding method is presented to generalize and impose the OT metric on FWI. This approach improves the convexity of the objective function and mitigates the cycle-skipping problem. The effectiveness of the proposed method is demonstrated numerically on an inversion task with the benchmark Marmousi model.

description: A promising method for measuring the cosmological parameter combination fsigma_8 is to compare observed peculiar velocities with peculiar velocities predicted from a galaxy density field using perturbation theory. We use N-body simulations and semi-analytic galaxy formation models to quantify the accuracy and precision of this method. Specifically, we examine a number of technical aspects, including the optimal smoothing length applied to the density field, the use of dark matter halos or galaxies as tracers of the density field, the effect of noise in the halo mass estimates or in the stellar-to-halo mass relation, and the effect of finite survey volumes. We find that for a Gaussian smoothing of 4 Mpc/h, the method has only small systematic biases at the level of 5%. Cosmic variance affects current measurements at the 5% level due to the volume of current redshift data sets.

Logarithmic corrections to higher twist scaling at strong coupling from AdS/CFT

description: We compute 1-loop correction E_1 to the energy of folded string in AdS_5 x S^5 (carrying spin S in AdS_5 and momentum J in S^5) using ``long string'' approximation in which S >> J >> 1. According to AdS/CFT E_1 should represent the first subleading correction to strong coupling expansion of anomalous dimension of higher twist SL(2) sector operators of the form Tr D^S Z^J. We show that E_1 smoothly interpolates between the ln S regime (previously found in the J=0 case) and the λ/J^2 ln^3 (S/J) regime (which is the leading correction to the thermodynamic limit on the spin chain side). This supports the universality of the ln S scaling. As in previous work, we also find ``non-analytic'' corrections related to non-trivial 1-loop phase in the corresponding Bethe ansatz S-matrix.

Modeling the delivery of dust from discs to ionized winds

description: A necessary first step for dust removal in protoplanetary disc winds is the delivery of dust from the disc to the wind. In the case of ionized winds, the disc and wind are sharply delineated by a narrow ionization front where the gas density and temperature vary by more than an order of magnitude. Using a novel method that is able to model the transport of dust across the ionization front in the presence of disc turbulence, we revisit the problem of dust delivery. Our results show that the delivery of dust to the wind is determined by the vertical gas flow through the disc induced by the mass loss, rather than turbulent diffusion (unless the turbulence is strong, i.e. $α\gtrsim 0.01$). Using these results we provide a simple relation between the maximum size of particle that can be delivered to the wind and the local mass-loss rate per unit area from the wind. This relation is independent of the physical origin of the wind and predicts typical sizes in the 0.01 -- $1\,μm$ range for EUV or X-ray driven winds. These values are a factor $\sim 10$ smaller than those obtained when considering only whether the wind is able to carry away the grains.

A model of the change process : an event-based study in couple therapy
Creators: name: Sweetman, Esther
Publisher: name: University of British Columbia
Year: 2009

description: The main purpose of this investigation was to develop a detailed model of the change process of an in-session therapeutic event co-created by therapist and couple in an alcohol recovery treatment context, using Experiential Systemic Therapy (ExST; Friesen, Grigg, Peel, & Newman, 1989). Two videotaped episodes in which a couple successfully resolved a relational impasse (RI event) and one episode in which a couple did not resolve a relational impasse were examined. To discover patterns that distinguished between the RI events that were successfully resolved and the RI event that was not, a step by step analysis of the therapist and couple behavior and interactions was conducted using Rice and Greenberg's (1984) Task Analytic Methodology. Key components and mechanisms of change in both therapist and couple performance and their interaction were identified. A model of the change process for the RI event specific to ExST is provided as well as a more general model that may be applied across theoretical approaches. Factors inhibiting the change process are also delineated. In addition, two process measures: The Experiencing Scale and the Self-Disclosure Coding System were found to discriminate between the successful and unsuccessful RI events. Finally, implications of the results for clinical practice and training, limitations of the study as well as recommendations for future directions in research are presented.

description: Σκοπός της παρούσας μελέτης ήταν να διερευνηθεί ο ρόλος της εξειδικευμένης προθέρμανσης της πετοσφαίρισης στο σπριντ με αλλαγές κατευθύνσεων μετά τη στατική διάταση σε 17 νεαρές αθλήτριες του αθλήματος, ηλικίας 14-16 ετών και προπονητικής ηλικίας 4 ετών. Όλες οι συμμετέχουσες εκτέλεσαν πρόγραμμα προθέρμανσης που περιλάμβανε γενική προθέρμανση, στατική διάταση στα κάτω άκρα, εξειδικευμένη προθέρμανση του αθλήματος και τρεις μετρήσεις σπριντ 36,5 μέτρων με αλλαγές κατευθύνσεων. H πρώτη μέτρηση σπριντ έγινε μετά τη γενική προθέρμανση, η δεύτερη μετά τη στατική διάταση και η τρίτη μετά την εξειδικευμένη προθέρμανση. Ο χρόνος του σπριντ μετρήθηκε με φωτοκύτταρα. Τα αποτελέσματα της μελέτης έδειξαν χειροτέρευση του χρόνου του σπριντ μετά τη στατική διάταση (p < 0.002) και αναστροφή του (p<0.015) με την εφαρμογή του εξειδικευμένου μέρους της προθέρμανσης. Από τα αποτελέσματα συμπεραίνεται, ότι η εξειδικευμένη προθέρμανση της πετοσφαίρισης που εφαρμόζεται στο δεύτερο μέρος της προθέρμανσης, όχι μόνο εξαλείφει τις αρνητικές επιδράσεις που προκαλούνται από τη στατική διάταση στο σπριντ, αλλά βελτιώνει και την επίδοσή του.
description: The purpose of the present study was to investigate the role of the specific volleyball warm-up in sprint with changes of directions after static stretching in 17 young female athletes of the sport, aged 14-16 years and 4 years of training period. All subjects performed a warm-up program that included a general warm up, static stretching of lower extremities, a specific warm-up of the sport and three measurements of 36.5 m sprint with changes of directions. The first measurement of the sprint was made after the general warm up, the second after the static stretching and the third after the specific warm-up. The time of the sprint was measured by photocells. The results of the study showed a decline of the sprint time after the static stretching (p<0.002) and reverse (p<0.015) after the performance of the specific part of the warm-up. The results concluded that the specific volleyball warm-up applied in the second part of a warm-up, not only eliminates the negative effects caused by static stretching in the sprint, but also improves the performance.

description: We investigate the effects of a time-delayed all-to-all coupling scheme in a large population of oscillators with natural frequencies following a bimodal distribution. The regions of parameter space corresponding to synchronized and incoherent solutions are obtained both numerically and analytically for particular frequency distributions. In particular we find that bimodality introduces a new time scale that results in a quasiperiodic disposition of the regions of incoherence.
