description: We present a re-analysis of 47 Rossi X-ray Timing Explorer observations of the 11Hz accreting pulsar IGR J17480-2446 in Terzan 5 during its 2010 outburst. We studied the fast-time variability properties of the source and searched for quasi-periodic oscillations (QPOs) in a large frequency range. General Relativity predicts that frame-dragging occurs in the vicinity of a spinning compact object and induces the precession of matter orbiting said object. The relativistic precession model predicts that this frame-dragging can be observed as QPOs with a characteristic frequency in the light curves of accreting compact objects. Such QPOs have historically been classified as horizontal branch oscillations in neutron star systems, and for a neutron star spinning at 11 Hz these oscillations are expected at frequencies below 1 Hz. However, previous studies of IGR J17480-2446 have classified QPOs at 35-50 Hz as horizontal branch oscillations, thus casting doubts on the frame-dragging nature of such QPOs. Here we report the detection of seven very low-frequency QPOs, previously undetected, with centroid frequencies below 0.3 Hz, and which can be ascribed to frame-dragging. We also discuss the possible nature of the QPOs detected at 35-50 Hz in this alternative scenario.

description: Within the post-form distorted wave Born approximation wherein pure Coulomb, pure nuclear and their interference terms are treated consistently in a single setup we study the beam energy dependence of the Coulomb-nuclear interference terms in the breakup of 11Be on a medium mass 44Ti target. Our results suggest that the Coulomb-nuclear interference terms are dependent on the incident beam energy and can be as big as that of the individual Coulomb or nuclear terms depending on the angle and energy of the breakup fragments. We also calculate the relative energy spectra and one-neutron removal cross sections in the breakup of 11Be on a heavy 208Pb target at 69 MeV/nucleon for two different angular ranges of the projectile center of the mass scattering angle and compare them with recently available experimental data.

description: We present spectra of six Type Ia and two Type II supernovae obtained in June 2002 at the William Herschel Telescope during a search for Type Ia supernovae (SNIa) at intermediate redshift. Supernova type identification and phase determination are performed using a fitting technique based on a Xi2 minimization against a series of model templates. The spectra range from z=0.033 to z=0.328, including one spectroscopically underluminous SNIa at z=0.033. This set of spectra significantly increases the sample of well-observed type SNIa supernovae available in the range 0.15< z <0.35. Together with the twelve supernovae observed by our team in 1999 in the same redshift range, they form an homogeneous sample of seventeen type Ia supernovae with comparable signal-to-noise ratio and regular phase sampling in a still largely unexplored region of the redshift space.

description: Το παρόν πόνημα, αναλύει το ανθρώπινο σύστημα ακοής και μελετά τις μουσικοπαιδαγωγικές προσεγγίσεις που αναπτύχθηκαν κατά κύριο λόγο κατά τη διάρκεια του 20ου αιώνα. Η ανάλυση αυτών έχει ως στόχο τη δημιουργία ενός προτύπου μουσικής διδασκαλίας για άτομα με προβλήματα ακοής. Εξάλλου είναι ευρέως γνωστό πως αξιόλογοι συνθέτες και μουσικοί είχαν προβλήματα ακοής ή ήταν κωφοί. Στη συνέχεια γίνεται αναφορά στο έργο τους και την προσωπικότητά τους. Παράλληλα με την ανάλυση των μουσικοπαιδαγωγικών προσεγγίσεων, είναι σημαντικό να γίνει αναφορά σε κάποιες θεωρίες μάθησης, οι οποίες αποτέλεσαν τη βάση της παιδαγωγικής. Έπειτα, γίνεται περιγραφή μιας μελέτης περίπτωσης, η οποία έλαβε χώρα στη Θεσσαλονίκη και αφορά τη διερεύνηση στην αντίληψη βασικών χαρακτηριστικών της μουσικής σε χρήστη κοχλιακού εμφυτεύματος, καθώς και την επανεξέταση του χρήστη αυτού μετά από συστηματική εκπαίδευση και ολοκλήρωση μιας σειράς συναντήσεων. Το ερώτημα που προκύπτει είναι εάν η συστηματική εκπαίδευση και οι συναντήσεις που πραγματοποιήθηκαν μπορούν να ενταχθούν σε μια ή περισσότερες μουσικοπαιδαγωγικές προσεγγίσεις με στόχο τη δημιουργία μιας μουσικοπαιδαγωγικής προσέγγισης που θα απευθύνεται σε άτομα με προβλήματα ακοής και συγκεκριμένα σε χρήστες ακουστικών προσθέσεων.
description: This work, analyzes the human hearing system and studies the musical-pedagogical approaches developed mainly during the 20th century. Their analysis aims to create a music model teaching for hearing impaired people. Besides, it is widely known as remarkable composers and musicians had hearing problems or were deaf. Reference is then made about their work and their personality. Along with the analysis of musical-pedagogical approaches, it is important to refer to some learning theories, which were the basis of pedagogy. Then, a description of one case study is made, that took place in Thessaloniki and concerns the investigation into understanding basic music features in a cochlear implant user, as well and reviewing this user after systematic training and integration a series of meetings. The question that arises is whether systematic education and meetings that have been held can fit into one or more musical-pedagogical approaches aimed at creating a musical education approach to hearing impaired people and users in particular acoustic implants.

description: Toxic or allelopathic compounds liberated by toxin-producing phytoplankton (TPP) acts as a strong mediator in plankton dynamics. On an analysis of a set of phytoplankton biomass-data that have been collected by our group in the North-West part of the Bay of Bengal, and by analysis of a three-component mathematical model under a constant as well as a stochastic environment, we explore the role of toxin-allelopathy in determining the dynamic behaviour of the competing-phytoplankton species. The overall results, based on analytical and numerical wings, demonstrate that toxin-allelopathy due to the toxin-producing phytoplankton (TPP) promotes a stable coexistence of those competitive phytoplankton that would otherwise exhibit competitive exclusion of the weak species. Our study suggests that TPP might be a potential candidate for maintaining the coexistence and diversity of competing phytoplankton species.

description: The interest in dynamic processes on networks is steadily rising in recent years. In this paper, we consider the $(α,β)$-Thresholded Network Dynamics ($(α,β)$-Dynamics), where $α\leq β$, in which only structural dynamics (dynamics of the network) are allowed, guided by local thresholding rules executed in each node. In particular, in each discrete round $t$, each pair of nodes $u$ and $v$ that are allowed to communicate by the scheduler, computes a value $\mathcal{E}(u,v)$ (the potential of the pair) as a function of the local structure of the network at round $t$ around the two nodes. If $\mathcal{E}(u,v) < α$ then the link (if it exists) between $u$ and $v$ is removed; if $α\leq \mathcal{E}(u,v) < β$ then an existing link among $u$ and $v$ is maintained; if $β\leq \mathcal{E}(u,v)$ then a link between $u$ and $v$ is established if not already present. The microscopic structure of $(α,β)$-Dynamics appears to be simple, so that we are able to rigorously argue about it, but still flexible, so that we are able to design meaningful microscopic local rules that give rise to interesting macroscopic behaviors. Our goals are the following: a) to investigate the properties of the $(α,β)$-Thresholded Network Dynamics and b) to show that $(α,β)$-Dynamics is expressive enough to solve complex problems on networks. Our contribution in these directions is twofold. We rigorously exhibit the claim about the expressiveness of $(α,β)$-Dynamics, both by designing a simple protocol that provably computes the $k$-core of the network as well as by showing that $(α,β)$-Dynamics is in fact Turing-Complete. Second and most important, we construct general tools for proving stabilization that work for a subclass of $(α,β)$-Dynamics and prove speed of convergence in a restricted setting.

description: We use first principles molecular dynamics simulations coupled to the thermodynamic integration method to study the hcp-bcc transition and melting of beryllium up to a pressure of 1600~GPa. We derive the melting line by equating solid and liquid Gibbs free energies, and represent it by a Simon Glatzel fit $T_m= 1564~\text{K} (1 + P/(15.6032 ~\text{GPa}))^{0.383}$, which is in good agreement with previous two-phase simulations below 6000~K. We also derive the hcp-bcc solid-solid phase boundary and show the quasiharmonic approximation underestimates the stability of the hcp structure, predicting lower transition pressures between hcp and bcc phases. However, our results are consistent with the stability regime predicted by the phonon quasiparticle method. We also predict that hcp-bcc-liquid triple point is located at 164.7~GPa and 4314~K. In addition, we compute the shock Hugoniot curve, and show that it is in good agreement with experiments, intersecting our derived melting curve at $\sim$235~GPa at 4900~K. Finally, we show that an isentropic compression path that intersects the melting curve at both low and high temperature in the liquid regime, can reappear in the solid after a gap as large as 7000~K. Therefore, we predict that a large section of the melting curve could be sampled, in principle, by a ramp compression experiment, where solid and liquid Be would coexist as the sample is compressed.

description: Annealing titania in vacuum while an external electrical field was applied resulted in the observation of structural, morphological and electrical anomalies. However, treating titania in vacuum leads to a redistribution of lattice defects. The diffusion of these lattice defects forms charge carrier trapping sites and permanent dipoles. The alignment of these dipoles leads to the formation of anisotropic conductive channels. Furthermore, the redistribution of lattice defects results in a new crystalline phase.

description: We present 3.6m ESO telescope spectroscopic observations of the system of the two blue compact dwarf galaxies SBS 0335-052W and SBS 0335-052E. The oxygen abundance in SBS 0335-052W is 12 + log O/H = 7.13 +/- 0.08, confirming that this galaxy is the most metal-deficient emission-line galaxy known. We find that the oxygen abundance in SBS 0335-052E varies from region to region in the range from 7.20 to 7.31, suggesting the presence of an abundance gradient over a spatial scale of 1 kpc. Signatures of early carbon-type Wolf-Rayet stars are detected in cluster 3 of SBS 0335-052E, corresponding to the emission of three to eighteen WC4 stars, depending on the adopted luminosity of a single WC4 star in the CIV 4658 emission line.

description: We present the structural and magnetic properties of KNaCuP$_2$O$_7$ investigated via x-ray diffraction, magnetization, specific heat, and $^{31}$P NMR and $^{23}$Na NMR measurements and complementary electronic structure calculations. The temperature dependent magnetic susceptibility and $^{31}$P NMR shift could be modeled very well by the uniform spin-$1/2$ Heisenberg antiferromagnetic chain model with nearest-neighbour interaction $J/k_{\rm B}\simeq 58.7$ K. The corresponding mapping using first principles electronic structure calculations leads to $J^{\rm DFT}/k_{\rm B} \simeq 59$ K with negligibly small inter-chain couplings ($J^{\prime}/k_{\rm B}$, $J^{\prime \prime}/k_{\rm B} < 0.1$ K), further confirming that the system is indeed an one-dimensional uniform spin-$1/2$ Heisenberg antiferromagnet. The temperature-dependent unit cell volume could be described well using the Debye approximation with a Debye temperature of $Θ_{\rm D} \simeq 294$ K, consistent with the heat capacity data. The diverging trend of the NMR spin-lattice relaxation rates ($^{31}1/T_1$ and $^{23}1/T_1$) imply the onset of a magnetic long-range-ordering at very low temperatures supporting the anticipated $T_{\rm N} \simeq 0.38$ K from the inter-chain couplings. Moreover, the NMR spin-lattice relaxation rates show the dominant contributions from uniform ($q=0$) and staggered ($q = \pm π/a$) spin fluctuations in the high and low temperature regimes, respectively mimicking one-dimensionality of the spin-lattice. We have also demonstrated that $^{31}1/T_1$ in high temperatures varies linearly with $1/\sqrt{H}$ reflecting the effect of spin diffusion on the dynamic susceptibility. Further, the inter-chain frustration also substantially impede the magnetic ordering rendering the spin-lattice a perfect one-dimensional uniform spin-$1/2$ Heisenberg antiferromagnet over a wide temperature range.

description: We have carried out a Schrodinger functional (SF) calculation for the SU(3) lattice gauge theory with two flavors of Wilson fermions in the sextet representation of the gauge group. We find that the discrete beta function, which governs the change in the running coupling under a discrete change of spatial scale, changes sign when the SF renormalized coupling is in the neighborhood of g^2=2.0. The simplest explanation is that the theory has an infrared-attractive fixed point, but more complicated possibilities are allowed by the data. While we compare rescalings by factors of 2 and 4/3, we work at a single lattice spacing.

description: We investigate the correlation between the bulge effective radius (r_e) and disk scale length (r_d), in the near-infrared K band for lenticular galaxies in the field and in clusters. We find markedly different relations between the two parameters as a function of luminosity. Lenticulars with total absolute magnitude fainter than M_T = -24.5 show a positive correlation, in line with predictions of secular formation processes for the pseudo bulges of late-type disk galaxies. But brighter lenticulars with M_T < -24.5 show an anti-correlation, indicating that they formed through a different mechanism. The available data are insufficient to reliably determine the effect of galaxy environment on this correlation.

description: The first--principles density functional molecular dynamics simulations have been carried out to investigate the geometric, the electronic, and the finite temperature properties of pure Li clusters (Li$_{10}$, Li$_{12}$) and Al--doped Li clusters (Li$_{10}$Al, Li$_{10}$Al$_2$). We find that addition of two Al impurities in Li$_{10}$ results in a substantial structural change, while the addition of one Al impurity causes a rearrangement of atoms. Introduction of Al--impurities in Li$_{10}$ establishes a polar bond between Li and nearby Al atom(s), leading to a multicentered bonding, which weakens the Li--Li metallic bonds in the system. These weakened Li--Li bonds lead to a premelting feature to occur at lower temperatures in Al--doped clusters. In Li$_{10}$Al$_2$, Al atoms also form a weak covalent bond, resulting into their dimer like behavior. This causes Al atoms not to `melt' till 800 K, in contrast to the Li atoms which show a complete diffusive behavior above 400 K. Thus, although one Al impurity in Li$_{10}$ cluster does not change its melting characteristics significantly, two impurities results in `surface melting' of Li atoms whose motions are confined around Al dimer.

description: Quantum phases with unusual symmetries may play a key role for the understanding of solid state systems at low temperatures. We propose a realistic scenario, well in reach of present experimental techniques, which should permit to produce a stationary quantum state with $d_{x^2-y^2}$-symmetry in a two-dimensional bosonic optical square lattice. This state, characterized by alternating rotational flux in each plaquette, arises from driven tunneling implemented by a stimulated Raman scattering process. We discuss bosons in a square lattice, however, more complex systems involving other lattice geometries appear possible.

description: The traditional approach in HEP analysis software is to loop over every event and every object via the ROOT framework. This method follows an imperative paradigm, in which the code is tied to the storage format and steps of execution. A more desirable strategy would be to implement a declarative language, such that the storage medium and execution are not included in the abstraction model. This will become increasingly important to managing the large dataset collected by the LHC and the HL-LHC. A new analysis description language (ADL) inspired by functional programming, FuncADL, was developed using Python as a host language. The expressiveness of this language was tested by implementing example analysis tasks designed to benchmark the functionality of ADLs. Many simple selections are expressible in a declarative way with FuncADL, which can be used as an interface to retrieve filtered data. Some limitations were identified, but the design of the language allows for future extensions to add missing features. FuncADL is part of a suite of analysis software tools being developed by the Institute for Research and Innovation in Software for High Energy Physics (IRIS-HEP). These tools will be available to develop highly scalable physics analyses for the LHC.

A full additive subcategory $\C$ of $R$-modules is triangulated if whenever two terms of a short exact sequence belong to $\C$, then so does the third term. In this note we give a classification of triangulated subcategories of finitely generated modules over a principal ideal domain. As a corollary we show that in the category of finitely generated modules over a PID, thick subcategories (triangulated subcategories closed under direct summands), wide subcategories (abelian subcategories closed under extensions) and Serre subcategories (wide subcategories closed under kernels) coincide and correspond to specialisation closed subsets of $\Spec(R)$.

description: The modeling of fast flavor evolution of neutrinos in dense environments has been traditionally carried out by relying on a two flavor approximation for simplicity. In addition, vacuum mixing has been deemed negligible. For the first time, we highlight that the fast flavor evolution in three flavors is intrinsically different from the one obtained in the two flavor approximation. This is due to the exponential growth of flavor mixing in the $e$--$μ$ and $e$--$τ$ sectors generated by the vacuum term in the Hamiltonian. As a result, substantially larger flavor mixing is found in three flavors. Our findings highlight that the two flavor approximation is not justified for fast pairwise conversion, even if the angular distributions of non-electron type neutrinos are initially identical.

description: We report on the detection of two Halpha-emitting extreme compact objects from deep images of the Abell 634 and Abell 539 clusters of galaxies at z ~ 0.03. Follow up long slit spectroscopy of these two unresolved sources revealed that they are members of their respective clusters showing HII type spectra. The luminosity and the extreme equivalent width of Halpha+[NII] measured for these sources, together with their very compact appearance, has raised the question about the origin of these intense starbursts in the cluster environment. We propose the compact starburst in Abell 539 resulted from the compression of the interstellar gas of a dwarf galaxy when entering the cluster core; while the starburst galaxy in Abell 634 is likely to be the result of a galaxy-galaxy interaction, illustrating the preprocessing of galaxies during their infall towards the central regions of clusters. The contribution of these compact star-forming dwarf galaxies to the star formation history of galaxy clusters is discussed, as well as a possible link with the recently discovered early-type ultra-compact dwarf galaxies. We note that these extreme objects will be rarely detected in normal magnitude-limited optical or NIR surveys, mainly due to their low stellar masses (of the order of 10^6 solar masses), whereas they will easily show up in dedicated Halpha surveys given the high equivalent width of their emission lines.

description: Highly sensitive and selective label free devices for real-time identification of specific biomarkers are expected to significantly impact the biosensing field. The ability of plasmonic systems to confine the light in nanometer volume and to manipulate it by tuning the size, shape and material features of the nanostructures, makes these systems promising candidates for biomedical devices. In this work we demonstrate the engineered sensing capabilities of a compact array of 3D metal dielectric core-shell chiral metamaterial. The intrinsic chirality of the nano-helices makes the system circular polarization dependent and unaffected by the background interferences, allowing to work even in complex environment. The core-shell architecture enhances the sensing properties of the chiral metamaterial on both in the far and near field, offering also a large surface to molecular immobilization. With our system we recorded sensitivity of about 800nm/RIU and FOM= 1276 RIU-1. The sensing abilities of the system is demonstrated with the detection of the of the TAR DNA-binding protein 43 (TDP-43) , a critical biomarker for the screening of neurodegenerative diseases. In particular, the sensor was tested in different environments, such as human serum, with concentrations ranging from 1pM down to 10fM, opening new perspectives for novel diagnostic tools.

description: We calculate parity-dependent level densities for the even-even isotopes 58,62,66 Fe and 58 Ni and the odd-A nuclei 59 Ni and 65 Fe using the Shell Model Monte Carlo method. We perform these calculations in the complete fp-gds shell-model space using a pairing+quadrupole residual interaction. We find that, due to pairing of identical nucleons, the low-energy spectrum is dominated by positive parity states. Although these pairs break at around the same excitation energy in all nuclei, the energy dependence of the ratio of negative-to-positive parity level densities depends strongly on the particular nucleus of interest. We find equilibration of both parities at noticeably lower excitation energies for the odd-A nuclei 59 Ni and 65 Fe than for the neighboring even-even nuclei 58 Ni and 66 Fe.

Η πρώτη συναντάται στον τομέα της Βιολογίας και ιδιαίτερα στη Πληθυσμιακή Γενετική, στην οποία σημαντικό ρόλο έχει η μελέτη των μηχανισμών που μεταβάλλουν τη γενετική δομή των πληθυσμών. Οι μηχανισμοί αυτοί είτε αυξάνουν την ποικιλία των πληθυσμών, όπως η μετάλλαξη, είτε μειώνουν την ποικιλία, όπως η γενετική παρέκκλιση και η φυσική επιλογή. Ως γενετική παρέκκλιση ορίζεται η αλλαγή στη συχνότητα των αλληλόμορφων λόγω των γεννήσεων και των θανάτων των οργανισμών. Στο πρώτο μέρος της εργασίας μελετάται το μοντέλο Moran (διαδικασία Moran), που είναι ένα εκ των δύο πιο γνωστών μοντέλων που περιγράφουν το μηχανισμό της γενετικής παρέκκλισης, ενώ στο δεύτερο η διαδικασία Τηλέγραφου. Πιο συγκεκριμένα, θα μελετηθεί η διαδικασία Τηλέγραφου Goldstein-Kac που περιγράφει την κίνηση ενός σωματιδίου στην ευθεία των πραγματικών αριθμών με σταθερή ταχύτητα, το οποίο εναλλάσει την κατεύθυνσή του ανάλογα με μία διαδικασία Poisson.

description: This presentation is referring on 2 stochastic processes. The first one can be found in the Biology sector and specifically in population genetics, in which important role has the study of the mechanisms that transform the genetic structure of thw populations. These mechanisms either can raise the variety of the populations, like the mutation, or can decrease the variety, like the genetic drift and the physical choice. Genetic drift is defined as the change on the sequence of the allele due to the births and deaths of the individuals. The first part of the presentation is referring on the Moran model (Moran process), which is one of the two most known modelsthat describe the mechanism of the genetic drift, while the two second part of the presentation is referring on the Telegraph process. More specific, it will be studied th procedure of Goldstein-Kac Telegraph, which describe the motion of a particle, in linear real numbers with constant speed, that can switch direction depending on a Poisson process. Applications of the stochastic Telegraph process can be found on Physics, Biology, even at the Economics sector, for the description of the prices of the stocks

description: Our data are random fields of multivariate Gaussian observations, and we fit a multivariate linear model with common design matrix at each point. We are interested in detecting those points where some of the coefficients are nonzero using classical multivariate statistics evaluated at each point. The problem is to find the $P$-value of the maximum of such a random field of test statistics. We approximate this by the expected Euler characteristic of the excursion set. Our main result is a very simple method for calculating this, which not only gives us the previous result of Cao and Worsley [Ann. Statist. 27 (1999) 925--942] for Hotelling's $T^2$, but also random fields of Roy's maximum root, maximum canonical correlations [Ann. Appl. Probab. 9 (1999) 1021--1057], multilinear forms [Ann. Statist. 29 (2001) 328--371], $\barχ^2$ [Statist. Probab. Lett 32 (1997) 367--376, Ann. Statist. 25 (1997) 2368--2387] and $χ^2$ scale space [Adv. in Appl. Probab. 33 (2001) 773--793]. The trick involves approaching the problem from the point of view of Roy's union-intersection principle. The results are applied to a problem in shape analysis where we look for brain damage due to nonmissile trauma.

Metallicity dependence of the H/H$_2$ and C$^+$/C/CO distributions in a resolved self-regulating interstellar medium

description: We study the metallicity dependence of the H/H$_2$ and C$^+$/C/CO distributions in a self-regulated interstellar medium (ISM) across a broad range of metallicities ($0.1 < Z/Z_\odot < 3$). To this end, we conduct high-resolution (particle mass of $1\ {\rm M_\odot}$) hydrodynamical simulations coupled with a time-dependent H$_2$ chemistry network. The results are then post-processed with an accurate chemistry network to model the associated C$^+$/C/CO abundances, based on the time-dependent non-steady-state (``non-equilibrium'') H$_2$ abundances. We find that the time-averaged star formation rate and the ISM structure are insensitive to metallicity. The column densities relevant for molecular shielding appear correlated with the volume densities in gravitationally unstable gas. As metallicity decreases, H$_2$ progressively deviates from steady state (``equilibrium'') and shows shallow abundance profiles until they sharply truncate at the photodissociation fronts. In contrast, the CO profile is sharp and controlled by photodissociation as CO quickly reaches steady state. We construct effective one-dimensional cloud models that successfully capture the time-averaged chemical distributions in simulations. At low metallicities, the steady-state model significantly overestimates the abundance of H$_2$ in the diffuse medium. The overestimated H$_2$, however, has little impact on CO. Consequently, the mass fraction of CO-dark H$_2$ gas is significantly lower than what a fully steady-state model predicts. The mass ratios of H$_2$/C$^+$ and H$_2$/C both show a weaker dependence on $Z^{\prime}$ than H$_2$/CO, which potentially indicates that C$^+$ and C could be alternative tracers for H$_2$ at low $Z^{\prime}$ in terms of mass budget. Our chemistry code for post-processing is publicly available.

description: We describe briefly the properties of the recently completed Southern African Large Telescope (SALT), along with its first light imager SALTICAM. Using this instrument, we present 4.3 hr of high speed unfiltered photometric observations of the eclipsing polar SDSSJ015543.40+002807.2 with time resolution as short as 112 ms, the highest quality observations of this kind of any polar to date. The system was observed during its high luminosity state. Two accreting poles are clearly seen in the eclipse light curve. The binary system parameters have been constrained: the white dwarf mass is at the low end of the range expected for cataclysmic variables. Correlations between the positions of the accretion regions on or near the surface of the white dwarf and the binary system parameters were established. The sizes of the accretion regions and their relative movement from eclipse to eclipse were estimated: they are typically 4-7 deg depending on the mass of the white dwarf. The potential of these observations will only fully be realised when low state data of the same kind are obtained and the contact phases of the eclipse of the white dwarf are measured.

description: To extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $|V_{ub}|$, we have re-analyzed all the available inputs (data and theory) on the $B\toπlν$ decays including the newly available inputs on the form-factors from light cone sum rule (LCSR) approach. We have reproduced and compared the results with the procedure taken up by the Heavy Flavor Averaging Group (HFLAV), while commenting on the effect of outliers on the fits. After removing the outliers and creating a comparable group of data-sets, we mention a few scenarios in the extraction of $|V_{ub}|$. In all those scenarios, the extracted values of $|V_{ub}|$ are higher than that obtained by HFLAV. Our best results for $|V_{ub}|^{exc.}$ are $(3.88 \pm 0.13)\times 10^{-3}$ and $(3.87 \pm 0.13)\times 10^{-3}$ in frequentist and Bayesian approaches, respectively, which are consistent with that extracted from inclusive decays $|V_{ub}|^{inc}$ within $1~σ$ confidence interval.
