description: Advances in deep learning have introduced a new wave of voice synthesis tools, capable of producing audio that sounds as if spoken by a target speaker. If successful, such tools in the wrong hands will enable a range of powerful attacks against both humans and software systems (aka machines). This paper documents efforts and findings from a comprehensive experimental study on the impact of deep-learning based speech synthesis attacks on both human listeners and machines such as speaker recognition and voice-signin systems. We find that both humans and machines can be reliably fooled by synthetic speech and that existing defenses against synthesized speech fall short. These findings highlight the need to raise awareness and develop new protections against synthetic speech for both humans and machines.

description: The next wave of wireless technologies is proliferating in connecting things among themselves as well as to humans. In the era of the Internet of things (IoT), billions of sensors, machines, vehicles, drones, and robots will be connected, making the world around us smarter. The IoT will encompass devices that must wirelessly communicate a diverse set of data gathered from the environment for myriad new applications. The ultimate goal is to extract insights from this data and develop solutions that improve quality of life and generate new revenue. Providing large-scale, long-lasting, reliable, and near real-time connectivity is the major challenge in enabling a smart connected world. This paper provides a comprehensive survey on existing and emerging communication solutions for serving IoT applications in the context of cellular, wide-area, as well as non-terrestrial networks. Specifically, wireless technology enhancements for providing IoT access in fifth-generation (5G) and beyond cellular networks, and communication networks over the unlicensed spectrum are presented. Aligned with the main key performance indicators of 5G and beyond 5G networks, we investigate solutions and standards that enable energy efficiency, reliability, low latency, and scalability (connection density) of current and future IoT networks. The solutions include grant-free access and channel coding for short-packet communications, non-orthogonal multiple access, and on-device intelligence. Further, a vision of new paradigm shifts in communication networks in the 2030s is provided, and the integration of the associated new technologies like artificial intelligence, non-terrestrial networks, and new spectra is elaborated. Finally, future research directions toward beyond 5G IoT networks are pointed out.

description: Dieser Essay beschreibt die ambivalenten und teilweise widersprüchlichen Emotionen, die Schreibende im Schreiben erleben können: von Versagensängsten, Konkurrenzdenken, Schreibstörungen und Schreibblockaden bis hin zur Lust am Schreiben als befreiende, kreative Technik. In Form eines Gedankenspiels geht der Essay der Frage nach, wie ein Ich als Ort beschaffen sein müsste, um diese Ambivalenzen und Widersprüche auszugleichen, damit Schreiben als persönlicher Erfolg wahrgenommen wird. Dieses Ich wird als Austragungsort gedeutet, an dem unterschiedliche Emotionen und Erfahrungen verarbeitet und in Einklang gebracht werden. Dabei wird es zum Ort der Kontrolle über das Selbst (Michel Foucault), an dem sich das (Schreib-)Ich eigenen Regeln unterwirft und sich in einem aufwendigen Akt selbst reguliert.

description: Presentation slides describing the content of scientific and technical papers are an efficient and effective way to present that work. However, manually generating presentation slides is labor intensive. We propose a method to automatically generate slides for scientific papers based on a corpus of 5000 paper-slide pairs compiled from conference proceedings websites. The sentence labeling module of our method is based on SummaRuNNer, a neural sequence model for extractive summarization. Instead of ranking sentences based on semantic similarities in the whole document, our algorithm measures importance and novelty of sentences by combining semantic and lexical features within a sentence window. Our method outperforms several baseline methods including SummaRuNNer by a significant margin in terms of ROUGE score.
Probing the intrinsic state of a one-dimensional quantum well with a photon-assisted tunneling

description: The photon-assisted tunneling (PAT) through a single wall carbon nanotube quantum well (QW) under influence an external electromagnetic field for probing of the Tomonaga Luttinger liquid (TLL) state is suggested. The elementary TLL excitations inside the quantum well are density ($ρ_{\pm}$) and spin ($σ_{\pm} $) bosons. The bosons populate the quantized energy levels $ε^{ρ+}_n =Δn/ g$ and $ε^{ρ-(σ\pm)}_n = Δn$ where $Δ= h v_F /L $ is the interlevel spacing, $n$ is an integer number, $L$ is the tube length, $g$ is the TLL parameter. Since the electromagnetic field acts on the $ρ_{+}$ bosons only while the neutral $ρ_{-}$ and $σ_{\pm} $ bosons remain unaffected, the PAT spectroscopy is able of identifying the $ρ_{+}$ levels in the QW setup. The spin $ε_n^{σ+} $ boson levels in the same QW are recognized from Zeeman splitting when applying a d.c. magnetic field $H \neq 0$ field. Basic TLL parameters are readily extracted from the differential conductivity curves.

Who is afraid of global history?

Publisher: name: Austrian Journal of Historical Studies

description: This essay debates the present state of global history from four angles: defining global history, debating global history, teaching global history, and researching global history. My comments and suggestions reflect my own experiences, but also configure and support the choices I make in my teaching and research missions. We are witnessing new, global shifts as the centuries-long hegemony of European and Western societies and theories are increasingly challenged. This urges us to broaden and deepen the paths of global history. This is an essential task since the topics that we are dealing with have never been bigger, the questions we are tackling have never been more important, and the stakes have never been higher.

Geotechnical characterization of mixed sandy and silty soils using piezocone tests: Analysis of partial drainage phenomena and rate effects on the experimental soil response
Creators: name: Garcia Martinez, Maria Fernanda <1986>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2014
Subjects: ICAR/07 Geotecnica

description: The cone penetration test (CPT), together with its recent variation (CPTU), has become the most widely used in-situ testing technique for soil profiling and geotechnical characterization. The knowledge gained over the last decades on the interpretation procedures in sands and clays is certainly wide, whilst very few contributions can be found as regards the analysis of CPT(u) data in intermediate soils.
Indeed, it is widely accepted that at the standard rate of penetration (v = 20 mm/s), drained penetration occurs in sands while undrained penetration occurs in clays. However, a problem arise when the available interpretation approaches are applied to cone measurements in silts, sandy silts, silty or clayey sands, since such intermediate geomaterials are often characterized by permeability values within the range in which partial drainage is very likely to occur. Hence, the application of the available and well-established interpretation procedures, developed for ‘standard’ clays and sands, may result in invalid estimates of soil parameters.
This study aims at providing a better understanding on the interpretation of CPTU data in natural sand and silt mixtures, by taking into account two main aspects, as specified below:   
1)Investigating the effect of penetration rate on piezocone measurements, with the aim of identifying drainage conditions when cone penetration is performed at a standard rate. This part of the thesis has been carried out with reference to a specific CPTU database recently collected in a liquefaction-prone area (Emilia-Romagna Region, Italy).
2)Providing a better insight into the interpretation of piezocone tests in the widely studied silty sediments of the Venetian lagoon (Italy). Research has focused on the calibration and verification of some site-specific correlations, with special reference to the estimate of compressibility parameters for the assessment of long-term settlements of the Venetian coastal defences.

description: We report on the discovery of a very bright z = 2.00 star-forming galaxy that is strongly lensed by a foreground z=0.422 luminous red galaxy (LRG). This system was found in a systematic search for bright arcs lensed by LRGs and brightest cluster galaxies in the Sloan Digital Sky Survey Data Release 5 sample. Follow-up observations on the Subaru 8.2m telescope on Mauna Kea and the Astrophysical Research Consortium 3.5m telescope at Apache Point Observatory confirmed the lensing nature of this system. A simple lens model for the system, assuming a singular isothermal ellipsoid mass distribution, yields an Einstein radius of 3.82 +/- 0.03 arcsec or 14.8 +/- 0.1 kpc/h at the lens redshift. The total projected mass enclosed within the Einstein radius is 2.10 +/- 0.03 x 10^12 M_sun/h, and the magnification factor for the source galaxy is 27 +/- 1. Combining the lens model with our gVriz photometry, we find an (unlensed) star formation rate for the source galaxy of 32 M_sun/h / yr, adopting a fiducial constant star formation rate model with an age of 100 Myr and E(B-V) = 0.25. With an apparent magnitude of r = 19.9, this system is among the very brightest lensed z >= 2 galaxies, and provides an excellent opportunity to pursue detailed studies of the physical properties of an individual high-redshift star-forming galaxy.

description: The accurate knowledge of the elastic properties of single-stranded DNA (ssDNA) is key to characterize the thermodynamics of molecular reactions that are studied by force spectroscopy methods where DNA is mechanically unfolded. Examples range from DNA hybridization, DNA ligand binding, DNA unwinding by helicases, etc. To date, ssDNA elasticity has been studied with different methods in molecules of varying sequence and contour length. A dispersion of results has been reported and the value of the persistence length has been found to be larger for shorter ssDNA molecules. We carried out pulling experiments with optical tweezers to characterize the elastic response of ssDNA over three orders of magnitude in length (60-14 k bases). By fitting the force-extension curves (FECs) to the Worm-Like Chain model we confirmed the above trend:the persistence length nearly doubles for the shortest molecule (60 b) with respect to the longest one (14 kb). We demonstrate that the observed trend is due to the different force regimes fitted for long and short molecules, which translates into two distinct elastic regimes at low and high forces. We interpret this behavior in terms of a force-induced sugar pucker conformational transition (C3'-endo to C2'-endo) upon pulling ssDNA.
Superstring measure and non-renormalization of the three-point amplitude

description: We show that a recently conjectured expression for the superstring three-point amplitude, in the framework of the Cacciatori, Dalla Piazza, van Geemen - Grushevsky ansatz for the chiral measure, fails to vanish at three-loop, in contrast with expectations from non-renormalization theorems. Based on analogous two-loop computations, we discuss the possibility of a non-trivial correction to the amplitude and propose a natural candidate for such a contribution. Thanks to a new remarkable identity, it is reasonable to expect that the corrected three-point amplitude vanishes at three-loop, recovering the agreement with non-renormalization theorems.

Directional photoelectric current across the bilayer graphene junction

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: A directional photon-assisted resonant chiral tunneling through a bilayer graphene barrier is considered. An external electromagnetic field applied to the barrier switches the transparency $T$ in the longitudinal direction from its steady state value T=0 to the ideal T=1 at no energy costs. The switch happens because the a.c. field affects the phase correlation between the electrons and holes inside the graphene barrier changing the whole angular dependence of the chiral tunneling (directional photoelectric effect). The suggested phenomena can be implemented in relevant experiments and in various sub-millimeter and far-infrared optical electronic devices.

description: An interesting, yet unknown, episode concerning the effective permeation of the scientific revolution in the XVIII century Kingdom of Naples (and, more generally, Italy) is recounted. The quite intriguing story of Watt's steam engine prepared for serving a Royal Estate of the King of Naples in Carditello reveals a fascinating piece of the history of that Kingdom, as well as an unknown step in the history of Watt's steam engine, whose final entrepreneurial success for the celebrated Boulton & Watt company was a direct consequence. That story unveils that, contrary to what claimed in the literature, the first introduction in Italy of the most important technological innovation of the XVIII century did not take place with the construction of the first steamship of the Mediterranean Sea, but rather 30 years before that, thanks to the incomparable work of Giuseppe Saverio Poli, a leading scholar and a very influential figure in the Kingdom of Naples. The tragic epilogue of Poli's engine testifies for its vanishing in the historical memory.

description: We use a generalization of chiral perturbation theory to account for the effects of flavor twisted boundary conditions in the Breit frame. The relevant framework for two light flavors is an SU(6|4) partially quenched theory, where the extra valence quarks differ only by their boundary conditions. Focusing on the pion electromagnetic form factor, finite volume corrections are calculated at next-to-leading order in the chiral expansion and are estimated to be small on current lattices.

description: This paper is concerned with the problem of coupling the N=8 superconformal Bagger-Lambert-Gustavsson (BLG) theory to N=8 conformal supergravity in three dimensions. We start by constructing the on-shell N=8 conformal supergravity in three dimensions consisting of a Chern-Simons type term for each of the gauge fields: the spin connection, the SO(8) R-symmetry gauge field and the spin 3/2 Rarita-Schwinger (gravitino) field. We then proceed to couple this theory to the BLG theory. The final theory should have the same physical content, i.e., degrees of freedom, as the ordinary BLG theory. We discuss briefly the properties of this "topologically gauged" BLG theory and why this theory may be useful.

Chaotic Einstein-Podolsky-Rosen pairs, measurements and time reversal

description: We consider a situation when evolution of an entangled Einstein-Podolsky-Rosen (EPR) pair takes place in a regime of quantum chaos being chaotic in the classical limit. This situation is studied on an example of chaotic pair dynamics described by the quantum Chirikov standard map. The time evolution is reversible even if a presence of small errors breaks time reversal of classical dynamics due to exponential growth of errors induced by exponential chaos instability. However, the quantum evolution remains reversible since a quantum dynamics instability exists only on a logarithmically short Ehrenfest time scale. We show that due to EPR pair entanglement a measurement of one particle at the moment of time reversal breaks exact time reversal of another particle which demonstrates only an approximate time reversibility. This result is interpreted in the framework of the Schmidt decomposition and Feynman path integral formulation of quantum mechanics. The time reversal in this system has already been realized with cold atoms in kicked optical lattices in absence of entanglement and measurements. On the basis of the obtained results we argue that the experimental investigations of time reversal of chaotic EPR pairs is within reach of present cold atom capabilities.

Slides for Webinar: Smarter Sustainable Cities
Artificial light absorbs 16,5% of the world’s electricity annual production. Today, we are witnessing a transition from the conventional “analogue” lighting technologies towards “digital” lighting. Smart lighting will become the backbone for smart cities and homes. Smart lighting concept leads towards the heart of the “Internet of Things”. Further, to serve society as effectively as we could, Industry has coined a new term “human-centric lighting” (HCL) to direct its primary efforts in meeting human needs. The objective is switching to smart human-centric lighting driven by both “efficiency” and “quality of light”. Next-generation lighting systems should provide the “Right Light” with the best efficiency and quality, when and where it is needed. This webinar will highlight all the above-mentioned issues and will focus on the future of the lighting systems and their contributions to the sustainable development of smart cities.

description: In recent years, a growing momentum has been gained by the emergent gravity framework. Within the latter, the very concepts of geometry and gravitational interaction are not seen as elementary aspects of Nature but rather as collective phenomena associated to the dynamics of more fundamental objects. In this paper we want to further explore this possibility by proposing a model of emergent Lorentzian signature and scalar gravity. Assuming that the dynamics of the fundamental objects can give rise in first place to a Riemannian manifold and a set of scalar fields we show how time (in the sense of hyperbolic equations) can emerge as a property of perturbations dynamics around some specific class of solutions of the field equations. Moreover, we show that these perturbations can give rise to a spin-0 gravity via a suitable redefinition of the fields that identifies the relevant degrees of freedom. In particular, we find that our model gives rise to Nordstrom gravity. Since this theory is invariant under general coordinate transformations, this also shows how diffeomorphism invariance (albeit of a weaker form than the one of general relativity) can emerge from much simpler systems.

description: Small neural networks with a constrained number of trainable parameters, can be suitable resource-efficient candidates for many simple tasks, where now excessively large models are used. However, such models face several problems during the learning process, mainly due to the redundancy of the individual neurons, which results in sub-optimal accuracy or the need for additional training steps. Here, we explore the diversity of the neurons within the hidden layer during the learning process, and analyze how the diversity of the neurons affects predictions of the model. As following, we introduce several techniques to dynamically reinforce diversity between neurons during the training. These decorrelation techniques improve learning at early stages and occasionally help to overcome local minima faster. Additionally, we describe novel weight initialization method to obtain decorrelated, yet stochastic weight initialization for a fast and efficient neural network training. Decorrelated weight initialization in our case shows about 40% relative increase in test accuracy during the first 5 epochs.

description: This article examines the ‘missionary space’ of the Catholic University of Beijing (Furen University), particularly studying how the Catholic visions of the Western missionary society in charge of the university, the Society of the Divine Word, negotiated with, cooperated, and ultimately came in conflict with the ideas of the Chinese faculty, embodied in the Chinese President of the university, Chen Yuan. It focuses on the moral and intellectual claims by both sides. I argue that moral claims mattered, and ultimately the Western missionary society lost its legitimacy due to actions that it took during and after the Second World War.

Soluzione Semine tempestive (seconda metà di marzo e prima decade di aprile) di varietà adatte su letti di semina ben preparati con file distanti 18-20 cm (si consiglia la tecnica della falsa semina), per sfruttare le piogge di fine inverno e assicurare un'efficace germinazione della coltura nonché una rapida copertura del suolo entro 4-5 settimane dalla semina.

description: Much effort has been invested in recent years, both observationally and theoretically, to understand the interacting processes taking place in planetary systems consisting of a hot Jupiter orbiting its star within 10 stellar radii. Several independent studies have converged on the same scenario: that a short-period planet can induce activity on the photosphere and upper atmosphere of its host star. The growing body of evidence for such magnetic star-planet interactions includes a diverse array of photometric, spectroscopic and spectropolarimetric studies. The nature of which is modeled to be strongly affected by both the stellar and planetary magnetic fields, possibly influencing the magnetic activity of both bodies, as well as affecting irradiation and non-thermal and dynamical processes. Tidal interactions are responsible for the circularization of the planet orbit, for the synchronization of the planet rotation with the orbital period, and may also synchronize the outer convective envelope of the star with the planet. Studying such star-planet interactions (SPI) aids our understanding of the formation, migration and evolution of hot Jupiters.

description: G305 star-forming complex was observed in the 3-2 lines of 12 & 13CO to investigate the effect of feedback from the central OB stars on the complex. The region was decomposed into clumps using dendrogram analysis. A catalog of the clump properties was created. The surface mass densities of the clumps were plotted as a function of the incident 8um flux. A mask of the region with 8um flux >100 MJy/sr was created and clumps were categorized based on the extent of overlap with the mask into "mostly inside" , "partly inside'", & "outside". The surface mass density distribution of each of these populations were plotted. This was followed by comparing the G305 clumps with the Galactic average taken from the ATLASGAL and CHIMPS clumps. Finally, the cumulative distribution functions (CDF) of the clump masses in G305 and their L/M ratios were compared to that of the Galactic sample. The surface mass densities of clumps showed a positive correlation with the incident 8um flux. The data did not have sufficient velocity resolution to discern the effects of feedback on the linewidths of the clumps. The sub-sample of clumps named "mostly inside" had the highest surface mass densities followed by "partly inside" and "outside" sub-samples. These differences between the three sub-samples were shown to be statistically significant using the KS test. The "mostly inside" sample also showed the highest level of fragmentation compared to the other two. These prove that the clumps inside the G305 region are triggered. The G305 clump population is also statistically different from the Galactic average population rejecting redistribution as a likely consequence of feedback. The CDFs of clump masses and their L/M ratios are both flatter than the Galactic average, indicating that feedback in G305 has triggered star formation. The collect and collapse method is the dominant mechanism at play in G305.

The "going private" transaction : a genre of minority shareholder squeezeout
Creators: name: Kroft, Edwin Grant
Publisher: name: University of British Columbia
Year: 2010

description: The phrase "going private" refers to a transaction in which the controlling shareholders who are instrumental in the management of a "public" company seek to terminate public participation and transform the firm into a private or closely-held entity. Minority shareholders of such companies located in Canada and the United States have described this process as unfair, disgraceful and a perversion of the whole financing process because of the ability of the insiders to time their departure, to dictate the amount of compensation they are to receive and to regulate the amount of disclosure which would otherwise enable them to judge the adequacy of the consideration offered. Consequently, they have sought to enjoin going private transactions on one of two grounds. On one hand, they have objected to being forced to give up their investment even at the fairest price, claiming, in effect, a vested right to remain as shareholders of the issuer. Alternatively, when the applicable corporate statute or constating documents of the Company expressly permit shareholder squeezeouts, they have complained of being deprived of the intrinsic or fair value of their shares and denied the procedural safeguards which would better enable them to make informed investment decisions. This thesis is directed to a study of these criticisms. Following a review of the assorted techniques used in squeezeout transactions and the existing procedural safeguards available to the minority, the claim by minority shareholders that they have a vested right to remain as shareholders of a public company is analyzed and rejected. Instead, it is argued that Canadian courts should only enjoin squeezeout transactions in jurisdictions which have not enacted legal rules designed to assist shareholders in commanding the intrinsic value of their shares. Assuming that an acquiror of minority shares has complied strictly with all corporate and securities procedural requirements, but the price offered for minority shares is less than their intrinsic value, an injunction should be issued only on the grounds that the opportunity to vote as a separate class, or the controlling shareholders or directors have committed a breach of a fiduciary duty owed to the Company.
Academic Tribes and Territories: the theoretical trajectory
Creators: name: Trowler, Paul
Publisher: name: Austrian Journal of Historical Studies
Year: 2014

description: This paper describes and reflects upon the Academic Tribes and Territories thesis as it has developed over 25 years and set out in two separate editions and a third book. The paper evaluates each of these books, setting out the developing thesis and in so doing describing a shift away from epistemological essentialism towards a more nuanced understanding of academic disciplines and their power. This is an understanding influenced by social practice theory and one which sees individual disciplines as constructed as well as enacted, with that construction influenced by contextual factors in academic departments, universities and more broadly.

description: We investigated the series of temperature and field-driven transitions in LuFe$_2$O$_4$ by optical and Mössbauer spectroscopies, magnetization, and x-ray scattering in order to understand the interplay between charge, structure, and magnetism in this multiferroic material. We demonstrate that charge fluctuation has an onset well below the charge ordering transition, supporting the "order by fluctuation" mechanism for the development of charge order superstructure. Bragg splitting and large magneto optical contrast suggest a low temperature monoclinic distortion that can be driven by both temperature and magnetic field.

description: I reduced the abstract up to 200 words if i reduce it more then the abstract will not give proper meaning) This research evaluates the quality and acceptability of 25%, 50%, and 75% fish protein concentrate (FPC) egg substituted cakes. Proximate chemical composition, batter and cake physical quality, microbial activity, and sensory evaluation were carried out. An impressive increase in protein, fats and ash content was noticed in GPSC. By increasing the FPC concentration, the viscosity of batters and cake volume decreased, while the specific gravity increased. In texture, the hardness, chewiness, and gumminess were increased while elasticity and cohesiveness were decreased with increase in substitution. An increase in substitution increased baking loss (BL) but reduced the water activity (aw) and the number and size of air bubbles in cake batter. By evaluating microbial activity, the total plate count (TPC) value increased, and the total fungal count (TFC) decreased while the cake crumb showed inconsistent change. The cake with 75% egg substitution was highly nutritious but displayed lower sensory attributes due to slight fishy flavor and dark color, while 25% and 50% GPSCs showed almost similar sensory attributes but nutritional value of 50% GPSC was higher than 25% GPSC. So, the cake with 50% substitution is a better option to prepare a good quality protein-enriched cake with acceptable sensory attributes.
Vortex pseudomomentum and dissipation in a superfluid vortex lattice

description: We propose an alternative approach to the dissipative vortex dynamics occurring in a superfluid vortex lattice at finite temperatures. Focusing upon the pseudomomentum of a vortex and its surrounding quasiparticles, we derive an equation of motion which, in spite of yielding the same evolution as the usual one for massless vortices, does not involve the vortex mass. This picture could provide further insights into the controversy about the nature of the vortex mass.
