 Comments. New record for Serbia. Prionomitus tiliaris was reared from four species of Cacopsylla (C. melanoneura, C. peregrina , C. pruni and C. pyrisuga). P. tiliaris has been previously recorded as a parasitoid of the following jumping plant-lice, C. melanoneura, C. peregrina, C. pyri, C. mali and C. ulmi (Novak 1994, Noyes 2017). Ferrière (1961) noted the strong affinity of Prionomitus tiliaris to immatures of C. peregrina, while Herard (1986) reported P. tiliaris on other hawthorn psyllids as well. In Italy, it was found to be an efficient parasitoid of C. pyri (Herard 1986). In the present study, P. tiliaris is recorded in association with Cacopsylla pruni and C. pyrisuga for the first time (Table 2).

Tax liability
Managers of s.a and l.t.d. companies
Tax debt
Τhe aim of this thesis was to study the personal liability of the s.a and ltd corporation managers for the taxes owned by the company. This liability is established without any manager’s fault. This is a liability under law, objective, unlimited, joint, but also subsidiary and subsequent. The study focused on the interpretation and application of the previous and the applicable legislation (Tax Procedure Code article 50) and also on the contradiction between the existing legislation and the problems that arise during the enforcement of the Law. Also, we examined the foundations of responsibility in specific categories of managers and specific forms of companies and attempted to solve the problems posed. In the end we examined all the possible ways to defend their interests before the Court. In conclusion, it became apparent the necessity for modification of the tax legislation regarding the managers’ liability, in order to provide a better legal protection.

Παράλληλα, εξετάστηκε η θεμελίωση της ευθύνης σε ειδικές κατηγορίες διοικούντων και σε ειδικές μορφές εταιριών και επιχειρήθηκε η επίλυση των προβλημάτων που ανακύπτουν Περαιτέρω, γίνεται εκτενής αναφορά στην παροχή της έννομης προστασίας των συνυπόχρεων προσώπων καθώς και τα επιβαλλόμενα από τη Διοίκηση μέτρα διασφάλισης του Δημοσίου. Συμπερασματικά, καταδεικνύεται η ανάγκη άμεσης και ουσιαστικής τροποποίησης των υφιστάμενων διατάξεων με σκοπό την ενίσχυση της έννομης προστασίας των εμπλεκόμενων προσώπων και την απαλλαγή τους από την ευθύνη, στις περιπτώσεις μη εμπλοκής τους στη δημιουργία των οφειλών.

description: There have been many attempts to derive continuum models for dense granular flow, but a general theory is still lacking. Here, we start with Mohr-Coulomb plasticity for quasi-2D granular materials to calculate (average) stresses and slip planes, but we propose a "stochastic flow rule" (SFR) to replace the principle of coaxiality in classical plasticity. The SFR takes into account two crucial features of granular materials - discreteness and randomness - via diffusing "spots" of local fluidization, which act as carriers of plasticity. We postulate that spots perform random walks biased along slip-lines with a drift direction determined by the stress imbalance upon a local switch from static to dynamic friction. In the continuum limit (based on a Fokker-Planck equation for the spot concentration), this simple model is able to predict a variety of granular flow profiles in flat-bottom silos, annular Couette cells, flowing heaps, and plate-dragging experiments -- with essentially no fitting parameters -- although it is only expected to function where material is at incipient failure and slip-lines are inadmissible. For special cases of admissible slip-lines, such as plate dragging under a heavy load or flow down an inclined plane, we postulate a transition to rate-dependent Bagnold rheology, where flow occurs by sliding shear planes. With different yield criteria, the SFR provides a general framework for multiscale modeling of plasticity in amorphous materials, cycling between continuum limit-state stress calculations, meso-scale spot random walks, and microscopic particle relaxation.

description: The core accretion model of giant planet formation has been challenged by the discovery of recycling flows between the planetary envelope and the disc that can slow or stall envelope accretion. We carry out 3D radiation hydrodynamic simulations with an updated opacity compilation to model the proto-Jupiter's envelope. To isolate the 3D effects of convection and recycling, we simulate both isolated spherical envelopes and envelopes embedded in discs. The envelopes are heated at given rates to achieve steady states, enabling comparisons with 1D models. We vary envelope properties to obtain both radiative and convective solutions. Using a passive scalar, we observe significant mass recycling on the orbital timescale. For a radiative envelope, recycling can only penetrate from the disc surface until $\sim$0.1-0.2 planetary Hill radii, while for a convective envelope, the convective motion can "dredge up" the deeper part of the envelope so that the entire convective envelope is recycled efficiently. This recycling, however, has only limited effects on the envelopes' thermal structure. The radiative envelope embedded in the disc has identical structure as the isolated envelope. The convective envelope has a slightly higher density when it is embedded in the disc. We introduce a modified 1D approach which can fully reproduce our 3D simulations. With our updated opacity and 1D model, we recompute Jupiter's envelope accretion with a 10 $M_{\oplus}$ core, and the timescale to runaway accretion is shorter than the disc lifetime as in prior studies. Finally, we discuss the implications of the efficient recycling on the observed chemical abundances of the planetary atmosphere (especially for super-Earths and mini-Neptunes).

description: Selective area growth (SAG) of semiconductors is a scalable method for fabricating gate-controlled quantum platforms. This letter reports on the adatom diffusion, incorporation, and desorption mechanisms that govern the growth rates of SAG nanowire (NW) arrays. We propose a model for the crystal growth rates that considers two parameter groups: the crystal growth control parameters and the design parameters. Using GaAs and InGaAs SAG NWs as platform we show how the design parameters such as NW pitch, width, and orientation have an impact on the growth rates. We demonstrate that by varying the control parameters (i.e. substrate temperature and beam fluxes) source, balance, and sink growth modes may exist in the SAG selectivity window. Using this model, we show that inhomogeneous growth rates can be compensated by tuning the design parameters.

description: Primordial black holes (PBHs) could account for all or part of dark matter, as well as for some LIGO events. We discuss the spins of primordial black holes produced in different cosmological scenarios, with the emphasis on recently discovered possibilities. PBHs produced as a horizon-size collapse of density perturbations are known to have very small spins. In contrast, PBHs resulting from assembly of matterlike objects (particles, Q-balls, oscillons, etc.) can have large or small spins depending on their formation history and the efficiency of radiative cooling. We show that scalar radiation can remove the angular momentum very efficiently, leading to slowly rotating PBHs in those scenarios for which the radiative cooling is important. Gravitational waves astronomy offers an opportunity to determine the spins of black holes, opening a new window on the early Universe if, indeed, some black holes have primordial origin.

description: A typical implementation of BB84 protocol for quantum communication uses four laser diodes for transmitting weak coherent pulses, which may not have the same characteristics. We have characterized these lasers for mismatch in various parameters such as spectral width, pulse width, spatial mode, peak wavelength, polarization and their arrival times at the receiver. This information is utilized to calculate possible information leakage through side channel attacks by evaluating mutual information between source and eavesdropper. Based on our experimental observations of cross correlation between parameter values for different laser diodes, we suggest ways to reduce information leakage to Eve.

description: We present detailed optical, near-infrared, and radio observations of the X-ray flash 050416a obtained with Palomar and Siding Springs Observatories as well as HST and the VLA, placing this event among the best-studied X-ray flashes to date. In addition, we present an optical spectrum from Keck LRIS from which we measure the redshift of the burst, z=0.6528. At this redshift the isotropic-equivalent prompt energy release was about 10^51 erg, and using a standard afterglow synchrotron model we find that the blastwave kinetic energy is a factor of 10 larger, E_K,iso ~ 10^52 erg. The lack of an observed jet break to t ~ 20 days indicates that the opening angle is larger than 7 deg and the total beaming-corrected relativistic energy is larger than 10^50 erg. We further show that the burst produced a strong radio flare at t ~ 40 days accompanied by an observed flattening in the X-ray band which we attribute to an abrupt circumburst density jump or an episode of energy injection (either from a refreshed shock or off-axis ejecta). Late-time observations with HST show evidence for an associated supernova with peak optical luminosity roughly comparable to that of SN 1998bw. Next, we show that the host galaxy of XRF 050416a is actively forming stars at a rate of at least 2 M_solar per year with a luminosity of L_B ~ 0.5L* and metallicity of Z ~ 0.2-0.8 Z_solar. Finally, we discuss the nature of XRF 050416a in the context of short-hard gamma-ray bursts and under the framework of off-axis and dirty fireball models for X-ray flashes.

description: We combine two non-perturbative approaches, one based on the two-particle-irreducible (2PI) action, the other on the functional renormalization group (fRG), in an effort to develop new non-perturbative approximations for the field theoretical description of strongly coupled systems. In particular, we exploit the exact 2PI relations between the two-point and four-point functions in order to truncate the infinite hierarchy of equations of the functional renormalization group. The truncation is "exact" in two ways. First, the solution of the resulting flow equation is independent of the choice of the regulator. Second, this solution coincides with that of the 2PI equations for the two-point and the four-point functions, for any selection of two-skeleton diagrams characterizing a so-called $Φ$-derivable approximation. The transformation of the equations of the 2PI formalism into flow equations offers new ways to solve these equations in practice, and provides new insight on certain aspects of their renormalization. It also opens the possibility to develop approximation schemes going beyond the strict $Φ$-derivable ones, as well as new truncation schemes for the fRG hierarchy.

description: The time- or temperature-resolved detector signal from a thermoluminescence dosimeter can reveal additional information about circumstances of an exposure to ionizing irradiation. We present studies using deep neural networks to estimate the date of a single irradiation with 12 mSv within a monitoring interval of 42 days from glow curves of novel TL-DOS personal dosimeters developed by the Materialprüfungsamt NRW in cooperation with TU Dortmund University. Using a deep convolutional network, the irradiation date can be predicted from raw time-resolved glow curve data with an uncertainty of roughly 1-2 days on a 68% confidence level without the need for a prior transformation into temperature space and a subsequent glow curve deconvolution. This corresponds to a significant improvement in prediction accuracy compared to a prior publication, which yielded a prediction uncertainty of 2-4 days using features obtained from a glow curve deconvolution as input to a neural network.

description: We present a high order perturbative computation of the renormalization constants Z_V, Z_A and of the ratio Z_P/Z_S for Wilson fermions. The computational setup is the one provided by the RI'-MOM scheme. Three- and four-loop expansions are made possible by Numerical Stochastic Perturbation Theory. Results are given for various numbers of flavours and/or (within a finite accuracy) for generic n_f up to three loops. For the case n_f=2 we also present four-loop results. Finite size effects are well under control and the continuum limit is taken by means of hypercubic symmetric Taylor expansions. The main indetermination comes from truncation errors, which should be assessed in connection with convergence properties of the series. The latter is best discussed in the framework of Boosted Perturbation Theory, whose impact we try to assess carefully. Final results and their uncertainties show that high-loop perturbative computations of Lattice QCD RC's are feasible and should not be viewed as a second choice. As a by-product, we discuss the perturbative expansion for the critical mass, also for which results are for generic n_f up to three loops, while a four-loop result is obtained for n_f=2.

Ακόμη, εκφράστηκε η άποψη ότι η απαρίθμηση των λόγων του ανυπόστατου δεν περιορίζεται στους λόγους του άρθρου 35γ αλλά είναι ενδεικτική. Προς επίρρωση της παραπάνω θέσης αναφέρθηκε η περίπτωση του άρθρου 32 παρ. 3 για τις αποφάσεις που λαμβάνονται δια περιφοράς πρακτικού. Τέλος, εξετάστηκε η νομική μεταχείριση των ανυπόστατων αποφάσεων και τις συνέπειες γεννώνται από τη λήψη τους.

description: As a black hole evaporates, each outgoing Hawking quantum carries away some of the black holes asymptotic charges associated with the extended Bondi-Metzner-Sachs group. These include the Poincaré charges of energy, linear momentum, intrinsic angular momentum, and orbital angular momentum or center-of-mass charge, as well as extensions of these quantities associated with supertranslations and super-Lorentz transformations, namely supermomentum, superspin and super center-of-mass charges (also known as soft hair). Since each emitted quantum has fluctuations that are of order unity, fluctuations in the black hole's charges grow over the course of the evaporation. We estimate the scale of these fluctuations using a simple model. The results are, in Planck units: (i) The black hole position has a uncertainty of $\sim M_i^2$ at late times, where $M_i$ is the initial mass (previously found by Page). (ii) The black hole mass $M$ has an uncertainty of order the mass $M$ itself at the epoch when $M \sim M_i^{2/3}$, well before the Planck scale is reached. Correspondingly, the time at which the evaporation ends has an uncertainty of order $\sim M_i^2$. (iii) The supermomentum and superspin charges are not independent but are determined from the Poincare charges and the super center-of-mass charges. (iv) The supertranslation that characterizes the super center-of-mass charges has fluctuations at multipole orders $l$ of order unity that that are of order unity in Planck units. At large $l$, there is a power law spectrum of fluctuations that extends up to $l \sim M_i^2/M$, beyond which the fluctuations fall off exponentially, with corresponding total rms shear tensor fluctuations $\sim M_i M^{-3/2}$.

The thermosonimetry of polymers
Creators: name: Soulsbury, Kevin Andrew
Publisher: name: University of British Columbia
Year: 2009

description: Thermosonimetry is the measurement of sound (acoustic emission) emitted from a substance as a function of temperature, while the substance is heated in a controlled manner. In this work the thermo-oxidative decompositions of poly(vinyl chloride), polyethylene, polypropylene, poly(ethylene terephthalate) and ethylene-vinyl acetate have been studied using thermosonimetry. The amount of acoustic emission produced was dependent on the polymer, the heating rate and the sample mass but not the molecular mass of the polymer. Thermosonimetry was also used to obtain apparent activation energies and the reaction orders for the thermo-oxidative decomposition processes under a variety of experimental conditions. Typically, the activation energies obtained were higher than values reported in the literature obtained using thermal analysis methods such as thermogravimetry. An apparatus has been developed that permits simultaneous thermogravimetric analysis (TG) and thermosonimetry (TS). The acoustic emission commenced at the maximum rate of mass loss, and confirmed that thermosonimetry was not suitable for measuring the relative thermal stability of polymers. Extensive chemical analysis of the polymer residues was used to study the decomposition mechanisms but did not reveal any direct link between the chemical structure of the polymers and the acoustic emission. Microscopic analysis of the residues, using scanning electron microscopy, suggested that the physical nature of the residues and the physical processes occurring during thermo-oxidative decomposition determined whether acoustic emission was produced. For PVC and PET, gas evolution and fracture processes were linked to the production of acoustic emission. For PE and PP, which did not produce significant amounts of acoustic emission, these processes were not observed to the same degree. Further studies sought to investigate whether acoustic emission was produced during other polymer processes. Polymerization and phase transitions did not produce acoustic emission. The crystallization of isotactic polypropylene was found to produce acoustic emission. The acoustic emission had been linked to the formation of cavities between the polymer spherulites. Thermosonimetry was also used to measure the rates of crystallization from the isothermal crystallization of polypropylene.
Multiplicity distribution of dipoles in QCD from Le, Mueller and Munier equation

description: In this paper we derived in QCD the BFKL linear, inhomogeneous equation for the factorial moments of multiplicity distribution($M_k$) from LMM equation. In particular, the equation for the average multiplicity of the color-singlet dipoles($N$) turns out to be the homogeneous BFKL while $M_k \propto N^k$ at small $x$. Second, using the diffusion approximation for the BFKL kernel we show that the factorial moments are equal to: $M_k=k!N( N-1)^{k-1}$ which leads to the multiplicity distribution:$ \frac{σ_n}{σ_{in}}=\frac{1}{N} ( \frac{N\,-\,1}{N})^{n - 1}$. We also suggest a procedure for finding corrections to this multiplicity distribution which will be useful for descriptions of the experimental data.

Spatiotemporal intermittency and scaling laws in the coupled sine circle map lattice

Year: 2006
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We study spatio-temporal intermittency (STI) in a system of coupled sine circle maps. The phase diagram of the system shows parameter regimes with STI of both the directed percolation (DP) and non-DP class. STI with synchronized laminar behaviour belongs to the DP class. The regimes of non-DP behaviour show spatial intermittency (SI), where the temporal behaviour of both the laminar and burst regions is regular, and the distribution of laminar lengths scales as a power law. The regular temporal behaviour for the bursts seen in these regimes of spatial intermittency can be periodic or quasi-periodic, but the laminar length distributions scale with the same power-law, which is distinct from the DP case. STI with traveling wave (TW) laminar states also appears in the phase diagram. Soliton-like structures appear in this regime. These are responsible for cross-overs with accompanying non-universal exponents. The soliton lifetime distributions show power law scaling in regimes of long average soliton life-times, but peak at characteristic scales with a power-law tail in regimes of short average soliton life-times. The signatures of each type of intermittent behaviour can be found in the dynamical characterisers of the system viz. the eigenvalues of the stability matrix. We discuss the implications of our results for behaviour seen in other systems which exhibit spatio-temporal intermittency.

description: Σκοπός της μεταπτυχιακής εργασίας ήταν να ερευνηθούν οι πρακτικές των καθηγητών της Γερμανικής Γλώσσας στο ελληνικό δημόσιο Γυμνάσιο σχετικά με τις στρατηγικές εκμάθησης λεξιλογίου. Ερευνήθηκε ποιες στρατηγικές εκμάθησης λεξιλογίου χρησιμοποιούνται στο μάθημα των Γερμανικών και ποιες από αυτές θεωρούνται ιδιαίτερα χρήσιμες. Επίσης σημαντικό ήταν να ερευνηθεί αν χρησιμοποιούνται στρατηγικές, οι οποίες λαμβάνουν υπ’ όψη την ιδιαιτερότητα της Γερμανικής ως Δεύτερης ξένης Γλώσσας (L3). Από την έρευνα διαφαίνεται και η συχνότητα χρήσης των στρατηγικών. Η διδακτική σειρά που χρησιμοποιείται στο μάθημα των Γερμανικών στο Γυμνάσιο είναι η «Deutsch- ein Hit!» και αποτελείται από τρεις τόμους. Καταγράφηκαν οι στρατηγικές που υπάρχουν στους τρείς τόμους και ερευνήθηκε σε ποιο βαθμό και πώς αυτές εντάσσονται στο μάθημα. Η μέθοδος που χρησιμοποιήθηκε για τη συλλογή δεδομένων ήταν το ερωτηματολόγιο στο οποίο πραγματοποιήθηκαν στατιστικές αναλύσεις και συγκρίσεις.
description: Objective of the thesis was to examine the practices teachers of German language use in Greek public high schools in terms of vocabulary learning strategies. It has been examined which vocabulary learning strategies are used in German lessons and which of these are considered particularly useful. It was also important to examine if strategies which take into account the specificity of German as a Second Foreign Language (L3) are used. The survey also shows which strategies are used more often. The course books used in German lessons in high school are "Deutsch- ein Hit!" and they consist of three volumes. Strategies existing in these books have been recorded and it was examined to what extent and how they are used in the lessons. The method used to collect data was the questionnaire in which statistical analyzes and comparisons were performed.

description: Στην παρούσα διπλωματική εργασία, μελετάμε το πρόβλημα της εκτίμησης Γκαουσιανού γραφικού μοντέλου από δεδομένα πολυμεταβλητής χρονοσειράς. Αρχικά, επιλύουμε το πρόβλημα της εκτίμησης των παραμέτρων ενός διανυσματικού αυτοπαλινδρομούμενου (VAR) μοντέλου, κάνοντας χρήση γνωστών μεθόδων εκτίμησης και στη συνέχεια επιλύουμε το αντίστροφο πρόβλημα της εύρεσης της τοπολογίας του γραφικού μοντέλου μέσω της μεθόδου Graphical Lasso. Στη συνέχεια, παρουσιάζουμε μεθόδους για την πρόβλεψη των συντελεστών ενός γραφικού μοντέλου αιτιότητας κατά Granger, από τους οποίους αποκαλύπτεται η δομή του αιτώδους δικτύου, δίνοντας έμφαση στη μέθοδο Lasso Granger, τον υπό συνθήκη δείκτη αιτιότητας κατά Granger (CGCI) και τον περιορισμένο υπό συνθήκη δείκτη αιτιότητας κατά Granger (RCGCI) , ανακαλύπτοντας έτσι την τοπολογία ενός δικτύου αιτιότητας κατά Granger. Τέλος, δημιουργούμε προσομοιώσεις για την αξιόλογηση των παραπάνω μεθόδων, κάνοντας χρήση στατιστικών μέτρων επίδοσης, όπως το F-score και τον συντελεστή συχέτισης του Mathew. Ολοκληρώνουμε την εργασία αυτή, κάνοντας εφαρμογή αυτών των μεθόδων σε πραγματικά δεδομένα EEG.
description: In this current thesis, we describe the estimation problem of a Gaussian Graphical Model on multivariate time series. Firstly, we solve the parameter estimation problem of VAR model via known estimation methods. Secondary, we solve the structure learning problem with the Graphical Lasso method choosing the best topology according to the different solutions of the problem. Afterwards, we study graphical Granger methods for predicting the structure of time series causality network, with emphasis on Lasso Granger, Conditional Granger Causality Index (CGCI) and Restricted Conditional Granger Causality Index (RCGCI). Finally, we do simulations for the evaluation of all these methods, using statistical measures like F-measure and Mathew's Correlation Coefficient and apply them to EEG data.

description: Analyzing a capillary minimizing problem for a higher-dimensional extended fluid, we find that there exist startling similarities between the black hole-black string system (the Gregory-Laflamme instability) and the liquid drop-liquid bridge system (the Rayleigh-Plateau instability), which were first suggested by a perturbative approach. In the extended fluid system, we confirm the existence of the critical dimension above which the non-uniform bridge (NUB, i.e., {\it Delaunay unduloid}) serves as the global minimizer of surface area. We also find a variety of phase structures (one or two cusps in the volume-area phase diagram) near the critical dimension. Applying a catastrophe theory, we predict that in the 9 dimensional (9D) space and below, we have the first order transition from a uniform bridge (UB) to a spherical drop (SD), while in the 10D space and above, we expect the transition such that UB $\to$ NUB $\to$ SD. This gives an important indication for a transition in the black hole-black string system.

Induced spontaneous symmetry breaking chain

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The article discusses a scenario based on the idea of induced spontaneous symmetry breaking. In this type of scenario, spontaneous symmetry breaking is assumed at some highest energy level, which leads to a chain of several subsequent induced symmetry violations at lower levels caused by small mixtures between levels. We present a simple model in which the idea is realized by small mixing between levels using scalar portals. In this approach, the large difference between energy scales, for example the Planck scale and the electroweak scale, occurs due to the product of several small factors proportional to the mixing coefficients. Dark matter fields can be formed in this scenario from matter fields on one or possibly several intermediate levels between the highest and lowest.

description: We experimentally study the dynamics of weakly interacting Bose-Einstein condensates of cesium atoms in a 1D optical lattice with a periodic driving force. After a sudden start of the driving we observe the formation of stable wave packets at the center of the first Brillouin zone (BZ) in momentum space, and we interpret these as Floquet solitons in periodically driven systems. The wave packets become unstable when we add a trapping potential along the lattice direction leading to a redistribution of atoms within the BZ. The concept of a negative effective mass and the resulting changes to the interaction strength and effective trapping potential are used to explain the stability and the time evolution of the wave packets. We expect that similar states of matter waves exist for discrete breathers and other types of lattice solitons in periodically driven systems.

description: Using a sample of 19,464 galaxies drawn from the DEEP2 Galaxy Redshift Survey, we study the relationship between galaxy color and environment at 0.4 < z < 1.35. We find that the fraction of galaxies on the red sequence depends strongly on local environment out to z > 1, being larger in regions of greater galaxy density. At all epochs probed, we also find a small population of red, morphologically early-type galaxies residing in regions of low measured overdensity. The observed correlations between the red fraction and local overdensity are highly significant, with the trend at z > 1 detected at a greater than 5-σlevel. Over the entire redshift regime studied, we find that the color-density relation evolves continuously, with red galaxies more strongly favoring overdense regions at low z relative to their red-sequence counterparts at high redshift. At z ~ 1.3, the red fraction only weakly correlates with overdensity, implying that any color dependence to the clustering of ~ L* galaxies at that epoch must be small. Our findings add weight to existing evidence that the build-up of galaxies on the red sequence has occurred preferentially in overdense environments (i.e., galaxy groups) at z < 1.5. The strength of the observed evolutionary trends at 0 < z < 1.35 suggests that the correlations observed locally, such as the morphology-density and color-density relations, are the result of environment-driven mechanisms (i.e., "nurture'') and do not appear to have been imprinted (by "nature'') upon the galaxy population during their epoch of formation.

description: We construct the CKM unitarity triangle from CP invariant quantities, using the coupling constant of weak decays with flavor change from b to u, and the particle - antiparticle mixing probability in the B_s and B_d systems. Also included are new measurements of the coupling V_us in Kaon decays. Of the two solutions, one agrees perfectly with the triangle constructed from CP violating processes in the K and B meson systems. The common solution yields a triangle with an area of J/2 = (1.51 +/- 0.09) x 10^{-5} and a CP violating phase gamma = 63.1^o +/- 4.0^o.
