description: We have observed a bimodal behaviour of the distribution of the asymmetry between the charges of the two heaviest products resulting from the decay of the quasi-projectile released in binary Xe+Sn and Au+Au collisions from 60 to 100 MeV/u. Event sorting has been achieved through the transverse energy of light charged particles emitted on the quasi-target side, thus avoiding artificial correlations between the bimodality signal and the sorting variable. Bimodality is observed for intermediate impact parameters for which the quasi-projectile is identified. A simulation shows that the deexcitation step rather than the geometry of the collision appears responsible for the bimodal behaviour. The influence of mid-rapidity emission has been verified. The two bumps of the bimodal distribution correspond to different excitation energies and similar temperatures. It is also shown that it is possible to correlate the bimodality signal with a change in the distribution of the heaviest fragment charge and a peak in potential energy fluctuations. All together, this set of data is coherent with what would be expected in a finite system if the corresponding system in the thermodynamic limit exhibits a first order phase transition.

description: Phishing attacks are the most common type of cyber-attacks used to obtain sensitive information and have been affecting individuals as well as organisations across the globe. Various techniques have been proposed to identify the phishing attacks specifically, deployment of machine intelligence in recent years. However, the deployed algorithms and discriminating factors are very diverse in existing works. In this study, we present a comprehensive analysis of various machine learning algorithms to evaluate their performances over multiple datasets. We further investigate the most significant features within multiple datasets and compare the classification performance with the reduced dimensional datasets. The statistical results indicate that random forest and artificial neural network outperform other classification algorithms, achieving over 97% accuracy using the identified features.

description: Given a Polish group $G$, let $E(G)$ be the right coset equivalence relation $G^ω/c(G)$, where $c(G)$ is the group of all convergent sequences in $G$. The connected component of the identity of a Polish group $G$ is denoted by $G_0$. Let $G,H$ be locally compact abelian Polish groups. If $E(G)\leq_B E(H)$, then there is a continuous homomorphism $S:G_0\rightarrow H_0$ such that $\ker(S)$ is non-archimedean. The converse is also true when $G$ is connected and compact. For $n\in{\mathbb N}^+$, the partially ordered set $P(ω)/\mbox{Fin}$ can be embedded into Borel equivalence relations between $E({\mathbb R}^n)$ and $E({\mathbb T}^n)$.

description: This volume covers Leg 78A of the cruises of the Drilling Vessel Glomar Challenger. This volume presents the initial scientific results of Deep Sea Drilling Project Leg 78A, which cored the seaward portions of the Lesser Antilles subduction complex on the eastern edge of the Barbados Ridge. Leg 78A was basically a drilling experiment to penetrate the toe of a particular type of accretionary complex at a convergent margin and reach materials whose eventual fate will either be subduction or underplating of the accretionary pile. The cores obtained document with considerable clarity the structure and style of deformation of the zone of active sediment accretion. A variety of downhole measurements provide important indications of the actual mechanics of faulting and deformation in the area. Leg 78A began and ended in San Juan, Puerto Rico and took place between February and March of 1981.

description: We investigated magneto-optical response of undoped Bi2Te3 films in the terahertz frequency range (0.3 - 5.1 THz, 10 - 170 cm-1) in magnetic fields up to 10 T. The optical transmission, measured in the Faraday geometry, is dominated by a broad Lorentzian-shaped mode, whose central frequency linearly increases with applied field. In zero field, the Lorentzian is centered at zero frequency, representing hence the free-carrier Drude response. We interpret the mode as a cyclotron resonance (CR) of free carriers in Bi2Te3. Because the mode's frequency position follows a linear magnetic-field dependence and because undoped Bi2Te3 is known to possess an appreciable number of bulk carriers, we associate the mode with a bulk CR. In addition, the cyclotron mass obtained from our measurements fits well the literature data on the bulk effective mass in Bi2Te3. Interestingly, the width of the CR mode demonstrates a behavior non-monotonous in field. We propose that the CR width is defined by two competing factors: impurity scattering, which rate decreases in increasing field, and electron-phonon scattering, which rate exhibits the opposite behavior.

description: From event-driven simulations of a gravity-driven channel flow of inelastic hard-disks, we show that the velocity distribution function remains close to a Gaussian for a wide range densities (even when the Knudsen number is of order one) if the walls are smooth and the particle collisions are nearly elastic. For dense flows, a transition from a Gaussian to a power-law distribution for the high velocity tails occurs with increasing dissipation in the center of the channel, irrespective of wall-roughness. For a rough wall, the near-wall distribution functions are distinctly different from those in the bulk even in the quasielastic limit.
D5.3 Discussion paper on the feasibility of changes in trade relations and instruments
Creators: name: Häberli, Christian
Publisher: name: Zenodo
Year: 2024

description: We place the question of change feasibility in the general context of food sustainability governance. Regrettably, our feasibility assessment must take account of SDG setbacks, the WTO and Climate Agreement sustainability gaps, structural debt crises, and the resulting challenges for regulators and operators. Our analysis also looks at various European Green Deal implementation problems and related WTO and AfCFTA issues. Through these narrowing transition pathways we present the MATS Case Study change proposals, classifying them along the four MATS-defined sustainability dimensions (1) Economy and Markets, (2) Social and Human, (3) Natural Capital, and (4) Policy, Governance and Regulation. Our feasibility assessment of these proposals in the light of national and international rules and principles (including the EU Green Deal), standards, and other social and environmental factors shows the implementation challenges and opportunities along the entire agri-food value chain. Although the global policy inertia appears to make changes even more difficult for MATS countries and products, and without opining on quality, we find that some proposals could be more easily implemented than others where further impact studies would be necessary, considering different, sometimes conflicting, views and interests. Most sustainability improvement actions will have to include hitherto ‘outsiders’ and vulnerable actors like smallholders, SME, women entrepreneurs, and even nomads. Public engagement and social and environmental stakeholder inclusiveness will thus be crucial to achieve the proposed changes. Moreover, all proposals will require consultations with all concerned regulators, operators, and business and CSO representatives – regardless of whether these proposals are addressed to one or all involved persons.

description: We acquired radial velocities of a significant number of globular clusters (GCs) on wide fields between galaxies in the nearby Fornax cluster of galaxies, in order to derive their velocity dispersion radial profile and to probe the dynamics of the cluster. We used FLAMES on the VLT to obtain accurate velocities for 149 GCs, within a ~500x150 kpc strip centered on NGC 1399, the Fornax central galaxy. These objects are at the very bright tail (M_V < -9.5) of the GC luminosity function, overlapping the so-called ``ultra-compact dwarfs'' magnitude range. Eight of the brightest FLAMES-confirmed members indeed show hints of resolution in the subarcsecond pre-imaging data we used for selecting the ~500 targets for FLAMES spectroscopy. Ignoring the GCs around galaxies by applying 3d_25 diameter masks, we find 61 GCs of 20.0 < V < 22.2 lying in the intra-cluster (IC) medium. The velocity dispersion of the population of ICGCs is 200 km/s at ~150 kpc from the central NGC 1399 and rises to nearly 400 km/s at 200 kpc, a value which compares with the velocity dispersion of the population of dwarf galaxies, thought to be infalling from the surroundings of the cluster.

Strong Griffiths singularities in random systems and their relation to extreme value statistics

description: We consider interacting many particle systems with quenched disorder having strong Griffiths singularities, which are characterized by the dynamical exponent, z, such as random quantum systems and exclusion processes. In several d=1 and d=2 dimensional problems we have calculated the inverse time-scales, t^{-1}, in finite samples of linear size, L, either exactly or numerically. In all cases, having a discrete symmetry, the distribution function, P(t^{-1},L), is found to depend on the variable, u=t^{-1}L^{z/d}, and to be universal given by the limit distribution of extremes of independent and identically distributed random numbers. This finding is explained in the framework of a strong disorder renormalization group approach when, after fast degrees of freedom are decimated out the system is transformed into a set of non-interacting localized excitations. The Frechet distribution of P(t^{-1},L) is expected to hold for all random systems having a strong disorder fixed point, in which the Griffiths singularities are dominated by disorder fluctuations.

description: Hard processes are a well calibrated probe to study heavy-ion collisions. However, the information to be gained from the nuclear suppression factor R_AA is limited, hene one has to study more differential observables to do medium tomography. The angular correlations of hadrons associated with a hard trigger appear suitable as they show a rich pattern when going from low p_T to high p_T. Of prime interest is the fate of away side partons with an in-medium pathlength O(several fm). At high p_T the correlations become dominated by the punchtrough of the away side parton with subsequent fragmentation. We discuss what information about the medium density can be gained from the data.

description: We propose to use the recently predicted two-dimensional `weak-pairing' $p_x + ip_y$ superfluid state of fermionic cold atoms as a platform for topological quantum computation. In the core of a vortex, this state supports a zero-energy Majorana mode, which moves to finite energy in the corresponding topologically trivial `strong-pairing' state. By braiding vortices in the `weak-pairing' state, unitary quantum gates can be applied to the Hilbert space of Majorana zero-modes. For read-out of the topological qubits, we propose realistic schemes suitable for atomic superfluids.
An explanation of the Z-track sources

description: We present an explanation of the Z-track phenomenon based on spectral fitting of RXTE observations of GX340+0 using the emission model previously shown to describe the dipping LMXB. In our Z-track model, the soft apex is a quiescent state of the source with lowest luminosity. Moving away from this point by ascending the normal branch the strongly increasing luminosity of the Accretion Disc Corona (ADC) Comptonized emission L_ADC provides substantial evidence for a large increase of mass accretion rate Mdot. There are major changes in the neutron star blackbody emission, kT increasing to high values, the blackbody radius R_BB decreasing, these changes continuing monotonically on both normal and horizontal branches. The blackbody flux increases by a factor of ten to three times the Eddington flux so that the physics of the horizontal branch is dominated by the high radiation pressure of the neutron star, which we propose disrupts the inner disc, and an increase of column density is detected. We further propose that the very strong radiation pressure is responsible for the launching of the jets detected in radio on the horizontal branch. On the flaring branch, we find that L_ADC is constant, suggesting no change in Mdot so that flaring must consist of unstable nuclear burning. At the soft apex, the mass accretion rate per unit area on the neutron star m_dot is minimum for the horizontal and normal branches and about equal to the theoretical upper limit for unstable burning. Thus it is possible that unstable burning begins as soon as the source arrives at this position, the onset being consistent with theory. The large increase in R_BB in flaring is reminiscent of radius expansion in X-ray bursts. Finally, in our model, Mdot does not increase monotonically along the Z-track as often previously thought.

description: Using particle simulations of the uniform shear flow of a rough dilute granular gas, we show that the translational and rotational velocities are strongly correlated in direction, but there is no orientational correlation-induced singularity at perfectly smooth ($β=-1$) and rough ($β=1$) limits for elastic collisions ($e=1$); both the translational and rotational velocity distribution functions remain close to a Gaussian for these two limiting cases. Away from these two limits, the orientational as well as spatial velocity correlations are responsible for the emergence of non-Gaussian high velocity tails. The tails of both distribution functions follow stretched exponentials, with the exponents depending on normal ($e$) and tangential ($β$) restitution coefficients.

Explicit expressions for the temperature and chemical potential dependence of the regulators in the FOCS theory are given in terms of the kinetic coefficients and constant relaxation time of the IS theory. Using the correspondence between the IS and FOCS theory, stability conditions for a charged fluid which are known in the FOCS approach are applied and one finds that the IS theory considered is unstable.

We identify the variation $δμ$ of the chemical potential of the electrodes as a function of the magnetization orientation as a key quantity that permits to tune the electrical properties of the device. Different effects occur depending on the relative size of $δμ$ and the charging energy. We provide preliminary quantitative estimates of $δμ$ using a very simple toy model for the electrodes.

Αν και ελληνικές παραδοσιακές απόψεις για τα φύλα και τις σχέσεις συνεχίζουν να επηρεάζουν, οι έμφυλες διαφορές φαίνονται να μειώνονται στο διαδίκτυο. Τα δύο φύλα περιγράφουν τον έρωτα, το γάμο, την οικογένεια, τις σχέσεις και τον εαυτό τους με νέους τρόπους που διαφοροποιούν τις έμφυλες ανισότητες στην αρχική φάση των ρομαντικών σχέσεων. Ειδικότερα, οι άνδρες φαίνονται να υπερβαίνουν όρια της παραδοσιακής «ανδρικής» ταυτότητας, επιβεβαιώνοντας την κρίση της, στην ελληνική σύγχρονη κοινωνία.
description: Although internet has provided new ways for people to meet, in Greece, a substantial body of research has examined romantic relationships that start through Internet. The present study examines the impact of Internet on romantic relationships and gender descriptions that occur in dating website, a less anonymous cyberspace. It is assumed that traditional gender stereotypes influence the ways that Internet users describe themselves and traditional gender roles influence their preferences about the perfect companion. As a result, although Greek traditional beliefs about gender and romantic relationships continue to have an impact, traditional differences between genders appears to be lessened. Men and women describe love, marriage, family, relationships and the self in new ways that alter gender inequalities, present in initial process of romantic relationships. Men, especially, seem to go beyond the traditional masculinity, confirming the crisis of male identity in contemporary Greek society.

description: On-chip electron sources have wide potential applications in miniature vacuum electronic devices and emission efficiency is one of their performance benchmarks. A cascade electron source based on series metal-insulator-metal horizontal tunneling junctions is proposed, where free electrons are additively extracted from each tunneling junction. A cascade electron source with n horizontal tunneling junctions shows a theoretical emission efficiency of approximately η(n)=1-(1-η_0 )^n, with η_0 being the efficiency of a single tunneling junction. Experimentally, a cascade electron source with three Si-SiOx-Si tunneling junctions is demonstrated, achieving an emission efficiency as high as 47.6%. This work provides a new way of realizing highly efficient on-chip electron sources.

description: At temperatures below the critical temperature of superfluid phase transition baryonic matter emits neutrinos by breaking and recombination of Cooper pairs formed in the condensate. The strong interactions in the nuclear medium modify the weak interaction vertices and the associated neutrino loss rates. We study these modifications non-perturbatively by summing infinite series of particle-hole loops in the S-wave superfluid neutron matter. The pairing and particle-hole interactions in neutron matter are described in the framework of the BCS and Fermi-liquid theories derived from microscopic interactions. Consistent with the f-sum rule, the leading order contribution to the polarization tensor arises at O(q^2) in the small momentum transfer, q, expansion. The associated neutrino emission rate is parametrically suppressed compared to its one-loop counterpart by a factor of the order of 5\times 10^{-3}, the parameter being the baryon recoil in units of temperature.

description: It is shown that the free-carrier (Drude) absorption of circularly polarized radiation in quantum well structures leads to an electric current flow. The photocurrent reverses its direction upon switching the light helicity. A pure orbital mechanism of such a circular photogalvanic effect is proposed that is based on interference of different pathways contributing to the light absorption. Calculation shows that the magnitude of the helicity dependent photocurrent in $n$-doped quantum well structures corresponds to recent experimental observations.

description: Electromagnetic waves with phase defects in the form of vortex lines combined with a constant magnetic field are shown to pin down cyclotron orbits (Landau orbits in the quantum mechanical setting) of charged particles at the location of the vortex. This effect manifests itself in classical theory as a trapping of trajectories and in quantum theory as a Gaussian shape of the localized wave functions. Analytic solutions of the Lorentz equation in the classical case and of the Schrödinger or Dirac equations in the quantum case are exhibited that give precise criteria for the localization of the orbits. There is a range of parameters where the localization is destroyed by the parametric resonance. Pinning of orbits allows for their controlled positioning -- they can be transported by the motion of the vortex lines.

description: This paper reanalyzes the low temperature nuclear quadrupole resonance (NQR) experiments in La(1.875)Ba(0.125)CuO(4) by Hunt et al. [Phys. Rev. B 64, 134565 (2001)] in an attempt to determine the dimensionality of spin modulations in this and other compounds of the lanthanum family of high temperature cuprate superconductors. It is concluded that the shape of the NQR spectra obtained by Hunt et al. favors the two-dimensional pattern of spin modulations known as "grid" or "checkerboard". The paper also contains the discussion of charge patterns, which can accompany the above spin modulation.

description: Σκοπός αυτής της μεταπτυχιακής εργασίας ήταν η ανάδειξη της άσκησης και της αγιότητας στο βίο του Γέροντος Παϊσίου του Αγιορείτου και πώς αυτά τα δυο στοιχεία προβάλλονται μέσα από το συγγραφικό του έργο. Εξετάσαμε την έννοια των όρων της άσκησης και της αγιότητας, καθώς και τη μεταξύ τους σχέση. Στη συνέχεια παρουσιάσαμε αναλυτικά ορισμένα χαρακτηριστικά γνωρίσματα της άσκησης που έκανε στη ζωή του ο Γέρων Παΐσιος. Ακόμη αναφερθήκαμε αναλυτικά σε όλα εκείνα τα στοιχεία που αποτελούν τεκμήρια της αγιότητας του σύγχρονου αγιορείτη ασκητή. Ένα άλλο θέμα που θίξαμε σε αυτή την εργασία ήταν το συγγραφικό έργο του Γέροντος Παϊσίου, κάνοντας μια συνοπτική παρουσίαση, ενώ εξετάσαμε πως ο ίδιος ως συγγραφέας προβάλλει τα στοιχεία της άσκησης και της αγιότητας στους διάφορους αγίους και χαρισματικούς ανθρώπους που βιογράφησε. Ολοκληρώσαμε την εργασία με τα συμπεράσματα που καταλήξαμε, ύστερα από τη μελέτη όλων των στοιχείων του θέματος που διαπραγματευτήκαμε.
description: The aim of this post-graduate thesis has been to highlight ascesis and holiness in the life of Elder Paisios the Hagiorite and how these two elements are manifested through his writings. The concepts of ascesis and holiness were examined, as well as the relation between them. Certain distinguishing characteristics of the ascesis that Elder Paisios conducted during his life were also presented in detail and detailed reference was made to all those elements that constitute evidence of the modern hagiorite ascetic’s holiness. Another subject touched in this project was the writings of Elder Paisios, of which a concise presentation was made, while examining how the elements of ascesis and holiness are propounded by himself as the author through the lives of the holy and charismatic people that he has written. The project was consummated with the conclusions reached after studying all the elements of the subject in question.

description: An overview of the recent efforts in point-contact (PC) spectroscopy of the nickel borocarbide superconductors RNi2B2C in the normal and superconducting (SC) state is given. The results of measurements of the PC electron- boson(phonon) interaction spectral function are presented. Phonon maxima and crystalline-electric-field (CEF) excitations are observed in the PC spectra of compounds with R=Dy, Ho, Er and Tm, while for R=Y a dominant phonon maximum around 12 meV is characteristic. Additionally, non-phonon and non-CEF maxima are observed near 3 meV in R=Ho and near 6 meV in R=Dy. Directional PC study of the SC gap gives evidence for the multi-band nature of superconductivity in R=Y, Lu. At low temperature the SC gap in R=Ho exhibits a standard single-band BCS-like dependence, which vanishes above T_c^*= 5.6K< T_c=8.5K, where a specifc magnetic ordering starts to play a role. For R=Tm (T_c=10.5 K) a decrease of the SC gap is observed below 5 K.

description: В конфликте героя и окружающего мира, заключается своеобразие такой группы персонажей В. Шукшина, как «задумавшиеся» и «мыслители». Эти герои находятся в состоянии философской дискуссии с миром либо вопрошают мир об интересующих их вопросах. Это проявляется в их рассуждениях о том, что они не понимают либо хотят понять. В конечном итоге философский конфликт неотделим от психологического и социального. Если герой соблюдает нравственные законы, верит в истину, привязан к месту, где родился он и его предки, то он оказывается в более благоприятном положении, чем те герои, кто гоняется за материальными благами. Поиски истины, хоть и причиняют героям Шукшина душевную боль, в конечном итоге становятся смыслом всей их жизни.

Kerr-Newman-de Sitter Solution on DGP Brane

description: We find an exact solution of Kerr-Newman-de Sitter type on the braneworld(4D) of the DGP model. When a constant 4D Ricci scalar is assumed, only zero(flat) and a positive(de-Sitter) values satisfy the Hamiltonian constraint equation coming from the extra dimension. With a Z_2-symmetry across the brane and a stationary and axisymmetric metric ansatz on the brane, we solve the constraint equation exactly in the Kerr-Schild form with de-Sitter background. In the de-Sitter background this Kerr-Schild solution is well behaved under Boyer-Lindquist transformation: the constraint equation is preserved under the transformation and so is the solution. In the non-rotating limit we show that this Kerr-Newman-de Sitter solution has the characteristic of accelerated expansion of the braneworld universe.

description: Frontier orbitals, i.e., the highest occupied and lowest unoccupied orbitals of a molecule, generally determine molecular properties, such as chemical bonding and reactivities. Consequently, there has been a lot of interest in measuring them, despite the fact that, strictly speaking, they are not quantum-mechanical observables. Yet, with photoemission tomography a powerful technique has recently been introduced by which the electron distribution in orbitals of molecules adsorbed at surfaces can be imaged in momentum space. This has even been used for the identification of reaction intermediates in surface reactions. However, so far it has been impossible to follow an orbital's momentum-space dynamics in time, for example through an excitation process or a chemical reaction. Here, we report a key step in this direction: we combine time-resolved photoemission employing high laser harmonics and a recently developed momentum microscope to establish a tomographic, femtosecond pump-probe experiment of unoccupied molecular orbitals. Specifically, we measure the full momentum-space distribution of transiently excited electrons. Because in molecules this momentum-space distribution is closely linked to orbital shapes, our experiment offers the extraordinary possibility to observe ultrafast electron motion in time and space. This enables us to connect their excited states dynamics to specific real-space excitation pathways.

Natural Higher-Derivatives Generalization for the Klein-Gordon Equation
Creators: name: Thibes, Ronaldo
Publisher: name: arXiv
Year: 2020
Subjects: subject: Mathematical Physics (math-ph)

description: We propose a natural family of higher-order partial differential equations generalizing the second-order Klein-Gordon equation. We characterize the associated model by means of a generalized action for a scalar field, containing higher-derivative terms. The limit obtained by considering arbitrarily higher-order powers of the d'Alembertian operator leading to a formal infinite-order partial differential equation is discussed. The general model is constructed using the exponential of the d'Alembertian differential operator. The canonical energy-momentum tensor densities and field propagators are explicitly computed. We consider both homogeneous and non-homogeneous situations. The classical solutions are obtained for all cases.
