description: The time evolution and spatial correlations of nonaffine displacements in deformed amorphous solids are investigated using molecular dynamics simulations. The three-dimensional model glass is represented via the binary mixture, which is slowly annealed well below the glass transition temperature and then sheared at a constant strain rate. It is shown that with increasing strain, the typical size of clusters of atoms with large nonaffine displacements increases, and these clusters remain spatially homogeneously distributed, until the yielding point when mobile atoms become localized within a system-spanning shear band. Furthermore, the yielding transition is associated with an abrupt change in the spatial correlation of nonaffine displacements, which varies from exponential to power-law decay. We also find that the height of the first peak in the pair correlation function of small atoms exhibits a distinct increase at the yielding strain. These results are discussed in relation to the yielding transition in amorphous materials under cyclic loading.

description: Recent models assessing the market impacts of Common Agricultural Policy (CAP) reforms are mostly static, non-stochastic and do not account for the risk attitude of farmers. This paper is a rst attempt to ll this gap. We develop a stochastic version of GTAP-AGR model in which we introduce exogenous productivity shocks and farmers' attitude towards risks. In addition to the expectation on mean price, the expectation on price volatility also becomes one of the key factors for the farmers' decisions through its inuence on risk premium. We show that under the endogenous modeling of the CAP instruments, risk aversion leads to larger production and price eects. The impacts are even larger if wealth eect is taken into consideration.

description: A survey was carried out to determine activity concentration levels and associated dose rates from the naturally occurring radionuclides Th-232, U-238, and K-40, in the various geological formations appearing throughout the geographically accessible area of Cyprus, by means of high-resolution gamma-ray spectrometry. A total number of 115 representative soil samples were collected from all over the bedrock surface of the island, based on the different lithological units of the study area, sieved through a fine mesh, sealed in 1000-mL plastic Marinelli beakers, and measured in the laboratory with respect to their gamma radioactivity for a counting time of 18 hours each. From the measured spectra, activity concentrations were determined for Th-232 (range from 1.0x10^-2 to 39.8 Bq/kg), U-238 (from 1.0x10^-2 to 39.3 Bq/kg) and K-40 (from 4.0x10^-2 to 565.8 Bq/kg). Gamma absorbed dose rates in air outdoors were calculated to be in the range of 1.1x10^-2 - 51.3 nGy/h, depending on the geological features, with an overall mean value of 8.7 nGy/h and a standard deviation of 8.4 nGy/h. This value is by a factor of about 7 below the corresponding population-weighted world-averaged value of 60 nGy/h reported by UNSCEAR (2000), and one of the lowest that has been reported from similar investigations worldwide. Assuming a 20% occupancy factor, the corresponding effective dose rates outdoors equivalent to the population were calculated to be between 1.3x10^-2 and 62.9 micro Sv/y, with an arithmetic mean value of 10.7 micro Sv/y and a standard deviation of 10.3 micro Sv/y.

description: This letter proposes using intermittent chaotic clocks, generated from chaotic maps, to drive cryptographic chips running the Advanced Encryption Standard as a countermeasure against Correlation Power Analysis attacks. Five different chaotic maps -- namely: the Logistic map, the Bernoulli shift map, the Henon map, the Tent map, and the Ikeda map -- are used in this work to generate chaotic clocks. The performance of these chaotic clocks is evaluated in terms of timing overhead and the resilience of the driven chip against Correlation Power Analysis attacks. All proposed chaotic clocking schemes successfully protect the driven chip against attacks, with the clocks produced by the optimized Ikeda, Henon, and Logistic maps achieving the lowest timing overhead. These optimized maps, due to their intermittent chaotic behavior, exhibit lower timing overhead compared to previous work. Notably, the chaotic clock generated by the optimized Ikeda map approaches the theoretical limit of timing overhead, i.e., half the execution time of a reference periodic clock.

description: We present a tunable microwave scattering device that allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. Transport in this device is nearly fully coherent. By comparison with quantum calculations, employing the modular recursive Green's-function method, the scattering wave function and the degree of residual decoherence can be determined. The parametric variation of Fano line shapes in terms of interacting resonances is analyzed.

Enabling Fast Exploration and Validation of Thermal Dissipation Requirements for Heterogeneous SoCs

description: The management of the energy consumption and thermal dissipation of multi-core heterogeneous platforms is becoming increasingly important as it can have direct impact on the platform performance. This paper discusses an approach that enables fast exploration and validation of heterogeneous system on chips (SoCs) platform configurations with respect to their thermal dissipation. Such platforms can be configured to find the optimal trade-off between performance and power consumption. This directly reflects in the head dissipation of the platform, which when increases over a given threshold will actually decrease the performance of the platform. Therefore, it is important to be able to quickly probe and explore different configurations and identify the most suitable one. However, this task is hindered by the large space of possible configurations of such platforms and by the time required to benchmark each configurations. As such, we propose an approach in which we construct a model of the thermal dissipation of a given platform using a system identification methods and then we use this model to explore and validate different configurations. The approach allows us to decrease the exploration time with several orders of magnitude. We exemplify the approach on an Odroid-XU4 board featuring an Exynos 5422 SoC.

description: In 4 dimensions, general relativity can be formulated as a constrained $BF$ theory; we show that the same is true in 2 dimensions. We describe a spinfoam quantization of this constrained BF-formulation of 2d riemannian general relativity, obtained using the Barrett-Crane technique of imposing the constraint as a restriction on the representations summed over. We obtain the expected partition function, thus providing support for the viability of the technique. The result requires the nontrivial topology of the bundle where the gravitational connection is defined, to be taken into account. For this purpose, we study the definition of a principal bundle over a simplicial base space. The model sheds light also on several other features of spinfoam quantum gravity: the reality of the partition function; the geometrical interpretation of the Newton constant, and the issue of possible finiteness of the partition function of quantum general relativity.

description: This paper describes the implementation of a system to recognize employees and visitors wanting to gain access to a physical office through face images and speech-to-text recognition. The system helps employees to unlock the entrance door via face recognition without the need of tag-keys or cards. To prevent spoofing attacks and increase security, a randomly generated code is sent to the employee, who then has to type it into the screen. On the other hand, visitors and delivery persons are provided with a speech-to-text service where they utter the name of the employee that they want to meet, and the system then sends a notification to the right employee automatically. The hardware of the system is constituted by two Raspberry Pi, a 7-inch LCD-touch display, a camera, and a sound card with a microphone and speaker. To carry out face recognition and speech-to-text conversion, the cloud-based platforms Amazon Web Services and the Google Speech-to-Text API service are used respectively. The two-step face authentication mechanism for employees provides an increased level of security and protection against spoofing attacks without the need of carrying key-tags or access cards, while disturbances by visitors or couriers are minimized by notifying their arrival to the right employee, without disturbing other co-workers by means of ring-bells.

description: In the aftermath of the world food price crisis, the issue of food and nutrition security has received a high level of political attention and the international donor community has repeatedly underlined its commitment to combat hunger in the world. In order to enhance the effectiveness of the international community’s efforts in addressing the widespread problem of malnutrition, we need to improve our knowledge on what activities donors are currently engaging in and which interventions have been shown to be successful. This paper offers both an overview of the aid for food and nutrition security landscape and how it has changed and an extensive review of the available evidence on the impact of a wide array of interventions aimed at addressing all four dimensions of food and nutrition security; availability, access, utilization and stability. We find that despite the renewed interest and elevated levels of funding for food and nutrition security assistance in developing countries, the empirical evidence base for the effectiveness of these interventions in improving beneficiaries’ food and nutrition security – although in several cases promising – is weak. In particular, the question whether different interventions improve the quality of food consumption and consequently nutrient intake and status, remains largely unanswered. Moreover, few studies assess longer-term effects and there exists relatively little rigorous evidence that compares different interventions. It is therefore strongly recommended to undertake additional research to improve the evidence base as this would allow researchers and policy makers to establish the type of approaches that improve food and nutrition security in the most efficient and cost-effective manner. Finally, in order to facilitate this process, there is a need for a clear and uniform definition of food and nutrition security assistance on the one hand as well as agreed upon, comprehensive indicators on the other hand.

description: We present a covariant approach to the problem of light beam propagation in a spacetime. We develop our considerations within the framework of classical geometric optics in general relativity. Using the concept of a screen surface orthogonal to the observer velocity and to the bundle of geodesics, we introduce covariant four-dimensional definitions for Sachs and Jacobi optical fields and for the area distance. Then we give relationships between them and derive their propagation equations together with initial conditions for these equations. Ultimately, for practical use, we transform the resulting formulas into the redshift-dependent form.

description: The second half of the 20th century brought breakthroughs in the field of science and technology, which significantly affected not only the growth of labour productivity and economic growth, but also brought changes in industrial structures and changes in share of individual industries in GDP. Even more strikingly, these changes have been reflected in the stock market, with leading companies from the field of information technology, which affect the flow and processing of information in revolutionary way. The onset of so-called internet economy at the beginning of the 1990s significantly changes also the structure of stock indices. Business services lure investors particularly into the area of financial services, which also show high degree of appreciation of the investment. New phenomenon nowadays is and expected changes in industrial structures not only in GDP, but also in the structure of stock markets will be brought by new phase of industrial revolution Industry 4.0. The aim of this paper is to quantify and analyse the current state and position of individual industries in the structure of GDP and stock indices and to outline new tendencies and to predict changes in these indicators with regards to the realization of 4th phase of industrial revolution.
MANDOLINE: Dynamic Slicing of Android Applications with Trace-Based Alias Analysis

description: Dynamic program slicing is used in a variety of tasks, including program debugging and security analysis. Building an efficient and effective dynamic slicing tool is a challenging task, especially in an Android environment, where programs are event-driven, asynchronous, and interleave code written by a developer with the code of the underlying Android platform. The user-facing nature of Android applications further complicates matters as the slicing solution has to maintain a low overhead to avoid substantial application slowdown. In this paper, we propose an accurate and efficient dynamic slicing technique for Android applications and implement it in a tool named MANDOLINE. The core idea behind our technique is to use minimal, low-overhead instrumentation followed by sophisticated, on-demand execution trace analysis for constructing a dynamic slice. We also contribute a benchmark suite of Android applications with manually constructed dynamic slices that use a faulty line of code as a slicing criterion. We evaluate MANDOLINE on that benchmark suite and show that it is substantially more accurate and efficient than the state-of-the-art dynamic slicing technique named ANDROIDSLICER.

description: As the number of actors involved rises, the world of development assistance is becoming increasingly complicated. In recent years, most donors have therefore recognized the need for more coherent and better coordinated aid efforts to improve aid effectiveness and avoid overlaps and unnecessary duplication of efforts. This paper investigates the coherence and coordination of European Union (EU) development policies aimed at enhancing food and nutrition security. We find that although EU has shown great political commitment towards enhancing the coordination of development policies, progress has been limited. A quantitative assessment of the distribution of EU aid for food and nutrition security for the period between 1995 and 2013, reveals that although the adoption of the Code of Conduct in 2007 appears to have set in motion a downward trend in the dispersion of aid - mostly through increased selectivity in terms of recipient countries – aid proliferation is still rampant. In addition, we find no evidence of improvements in terms of overlap between EU Institutions’ and Member States’ efforts.

title: Tramps and their Excuses: A Study of the Writing of Travellers in Borneo in the 19th and 20th Centuries
Creators: name: Millum, Trevor
Publisher: name: The Open University
Year: 1993

description: The aim of the study was to examine travel writing over a significant period of time in order to understand more about the nature of travel writing in itself and to determine what changes may have taken place within the genre over time. A secondary aim was to carry out an exploration of the S E Asia Collection in the Library of the University of Hull. In order to focus the study on a manageable body of work, the geographical area was narrowed to that of the island of Borneo and the texts to those of book-length. The study began with a reading of a wide range of material which related to the subject of the thesis. From this essentially exploratory bibliographical research arose three things. Firstly, a body of material which could be reasonably defined as travel writing about Borneo was identified. Secondly, a broad categorization of sub-groups within that body of material began to emerge. Coincidentally, further ideas about the nature of travel writing, particularly in the context of the exploitation of East by the West, developed. There followed a detailed and careful review of the texts which served to refine the characteristics of the sub-groups and show the ways in which changes in the genre had taken place over time. The thesis concludes that while there have been significant changes in the nature of travel writing, there is an interesting degree of continuity, for example, curiosity as a motivating force and confidence as a characteristic., And where a writer writes from within the role of explorer, there is a remarkable number of characteristics which remain constant over time. Throughout the period under study, different kinds of writer have become travellers, with varying motives, producing new kinds of travel writing: as the world has become smaller, the focus of the travel writer has become narrower and the ethos more personal.

Indications for Criticality at Zero Curvature in a 4d Regge Model of Euclidean Quantum Gravity

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We re-examine the approach to four-dimensional Euclidean quantum gravity based on the Regge calculus. A cut-off on the link lengths is introduced and consequently the gravitational coupling and the cosmological constant become independent parameters. We determine the zero curvature, $ =0$, line in the coupling constant plane by numerical simulations. When crossing this line we find a strong, probably first order, phase transition line with indications of a second order endpoint. Beyond the endpoint the transition through the $ =0$ line appears to be a crossover. Previous investigations, using the Regge or the Dynamical Triangulation approach, dealt with a limit in which the first order transition prevails.

Interaction of forced Orr-Sommerfeld and Squire modes in a low-order representation of turbulent channel flow

description: A resolvent-based reduced-order representation is used to capture time-averaged second-order statistics in turbulent channel flow. The recently-proposed decomposition of the resolvent operator into two distinct families related to the Orr-Sommerfeld and Squire operators [K. Rosenberg and B. J. McKeon, Efficient representation of exact coherent states of the Navier-Stokes equations using resolvent analysis, Fluid Dynamics Research 51, 011401 (2019)] results in dramatic improvement in the ability to match all components of the energy spectra and the $uv$ cospectrum. The success of the new representation relies on the ability of the Squire modes to compete with the vorticity generated by Orr-Sommerfeld modes, which is demonstrated by decomposing the statistics into contributions from each family. It is then shown that this competition can be used to infer a phase relationship between the two sets of modes. Additionally, the relative Reynolds number scalings for the two families of resolvent weights are derived for the universal classes of resolvent modes presented by Moarref et al. [R. Moarref, A. S. Sharma, J. A. Tropp, and B. J. McKeon, Model-based scaling of the streamwise energy density in high-Reynolds-number turbulent channels, Journal of Fluid Mechanics 734, 275 (2013)]. These developments can be viewed as a starting point for further modeling efforts to quantify nonlinear interactions in wall-bounded turbulence.

description: We present extensive multi-frequency VLA and VLBA observations of the radio-bright supernova (SN) IIb SN 2004C that span $\sim(40-2793)$ days post-explosion. We interpret the temporal evolution of the radio spectral energy distribution (SED) in the context of synchrotron self-absorbed (SSA) emission from the explosion's forward shock as it expands in the circumstellar medium (CSM) previously sculpted by the mass-loss history of the stellar progenitor. VLBA observations and modeling of the VLA data point to a blastwave with average velocity $\sim0.06c$ that carries an energy of $\sim 10^{49}$ erg. Our modeling further reveals a flat CSM density profile $ρ_{\rm{CSM}} \propto R^{-0.03 \pm0.22}$ up to a break radius $R_{br} \approx (1.96 \pm 0.10) \times 10^{16}$ cm, with a steep density gradient following $ρ_{\rm{CSM}} \propto R^{-2.3 \pm 0.5}$ at larger radii. We infer that the flat part of the density profile corresponds to a CSM shell with mass $\sim0.021 M_{\odot}$, and that the progenitor's effective mass-loss rate varied with time over the range $(50-500) \times 10^{-5} M_{\odot} \rm{yr}^{-1}$ for an adopted wind velocity $v_w =1000$ km $s^{-1}$ and shock microphysical parameters $ε_e = 0.1, ε_B = 0.01$. These results add to the mounting observational evidence for departures from the traditional single-wind mass-loss scenarios in evolved, massive stars in the centuries leading up to core collapse. Potentially viable scenarios include mass loss powered by gravity waves and/or interaction with a binary companion.

description: System testing through the Graphical User Interface (GUI) is a valuable form of Verification & Validation for modern applications, especially in graphically-intensive domains like web and mobile applications. However, the practice is often overlooked by developers mostly because of its costly nature and the absence of immediate feedback about the quality of test sequence. This paper describes a proposal for the Gamification of exploratory GUI testing. We define - in a tool and domain-agnostic way - the basic concepts, a set of metrics, a scoring scheme and visual feedbacks to enable a gamified approach to the practice; we finally discuss the potential implications and envision a roadmap for the evaluation of the approach.

We also show that the only linear combinations of Hodge numbers that are birational invariants of $X$ are given by the span of the $h^{i,0}(X)$ and the $h^{0,j}(X)$ (and their duals $h^{i,n}(X)$ and $h^{n,j}(X)$). The corresponding statements for compact Kähler manifolds were proven by Kotschick and Schreieder.

description: The study of the evolution of a suprathermal electron beam traveling through a background plasma is relevant for the physics of solar flares and their associated type III solar radio bursts. As they evolve guided by the coronal magnetic field-lines, these beams generate Langmuir turbulence. The beam-generated turbulence is in turn responsible for the emission of radio photons at the second harmonic of the local plasma frequency, which are observed during type III solar radio bursts. To generate the radio emission, the beam-aligned Langmuir waves must coalesce, and therefore a process capable of re-directioning the turbulence in an effective fashion is required. Different theoretical models identify the electrostatic (ES) decay process L1 -> L2 + S (L: Langmuir wave; S: Ion-acoustic wave) as the re-directioning mechanism for the L waves. Two different regimes have been proposed to play a key role: the back-scattering and the diffusive (small angle) scattering. This paper is a comparative analysis of the decay rate of the ES decay for each regime, and of the different observable characteristics that are expected for the resulting ion-acoustic waves.

description: This study uses the nonlinear autoregressive distributive lag (N-ARDL) model to investigate the expenditure-revenue relationship for all nine South African provinces using annual data spanning from 2000 to 2016. Whereas other cointegration models can only depict whether budgets are sustainable or not, the N-ARDL model presents features which further enable us to predict a course of action which individual provincial governments can take towards attaining higher levels of budgetary sustainability in both the short and the long-run. Ultimately, our empirical study demonstrates that the ‘one rule fit all’ strategy as suggested by previous studies may not be an appropriate approach seeing that provincial governments have differing requirements for attaining improved levels of budget sustainability

description: State-of-the-art spectral energy distribution (SED) analyses use a Bayesian framework to infer the physical properties of galaxies from observed photometry or spectra. They require sampling from a high-dimensional space of SED model parameters and take $>10-100$ CPU hours per galaxy, which renders them practically infeasible for analyzing the $billions$ of galaxies that will be observed by upcoming galaxy surveys ($e.g.$ DESI, PFS, Rubin, Webb, and Roman). In this work, we present an alternative scalable approach to rigorous Bayesian inference using Amortized Neural Posterior Estimation (ANPE). ANPE is a simulation-based inference method that employs neural networks to estimate the posterior probability distribution over the full range of observations. Once trained, it requires no additional model evaluations to estimate the posterior. We present, and publicly release, ${\rm SED}{flow}$, an ANPE method to produce posteriors of the recent Hahn et al. (2022) SED model from optical photometry. ${\rm SED}{flow}$ takes ${\sim}1$ $second~per~galaxy$ to obtain the posterior distributions of 12 model parameters, all of which are in excellent agreement with traditional Markov Chain Monte Carlo sampling results. We also apply ${\rm SED}{flow}$ to 33,884 galaxies in the NASA-Sloan Atlas and publicly release their posteriors: see https://changhoonhahn.github.io/SEDflow.

De Sitter Space With Finitely Many States: A Toy Story

description: The finite entropy of de Sitter space suggests that in a theory of quantum gravity there are only finitely many states. It has been argued that in this case there is no action of the de Sitter group consistent with unitarity. In this note we propose a way out of this if we give up the requirement of having a hermitian Hamiltonian. We argue that some of the generators of the de Sitter group act in a novel way, namely by mixing in- and out-states. In this way it is possible to have a unitary S-matrix that is finite-dimensional and, moreover, de Sitter-invariant. Using Dirac spinors, we construct a simple toy model that exhibits these features.

description: Generally, in any human field, a Smarandache Structure on a set A means a weak structure W on A such that there exists a proper subset B contained in A which is embedded with a stronger structure S. These types of structures occur in our everyday's life, that's why we study them in this book. Thus, as a particular case: A non-associative ring is a non-empty set R together with two binary operations '+' and '.' such that (R, +) is an additive abelian group and (R, .) is a groupoid. For all a, b, c belonging to R we have (a + b) . c = a . c + b . c and c . (a + b) = c . a + c . b. A Smarandache non-associative ring is a non-associative ring (R, +, .) which has a proper subset P contained in R, that is an associative ring (with respect to the same binary operations on R).

The 3.4 μm absorption of the Titan's stratosphere: contribution of ethane, propane, butane and complex hydrogenated organics

description: The complex organic chemistry harbored by the atmosphere of Titan has been investigated in depth by Cassini observations. Among them, a series of solar occultations performed by the VIMS instrument throughout the 13 years of Cassini revealed a strong absorption centered at 3.4 $μ$m. Several molecules present in Titan's atmosphere create spectral features in that wavelength region, but their individual contributions are difficult to disentangle. In this work, we quantify the contribution of the various molecular species to the 3.4 $μ$m band using a radiative transfer model. Ethane and propane are a significant component of the band but they are not enough to fit the shape perfectly, then we need something else. Polycyclic Aromatic Hydrocarbons (PAHs) and more complex polyaromatic hydrocarbons like Hydrogenated Amorphous Carbons (HACs) are the most plausible candidates because they are rich in C-H bonds. PAHs signature have already been detected above ~900 km, and they are recognized as aerosols particles precursors. High similarities between individual spectra impede abundances determinations.
The Riddle of Polarization in $B \to VV$ Transitions

description: Measurements of polarization fractions in $B \to VV$ transitions, with $V$ a light vector meson, show that the longitudinal amplitude dominates in $B^0 \to ρ^+ ρ^-$, $B^+ \to ρ^+ ρ^0$, and $B^+ \to ρ^0 K^{*+}$ decays and not in the penguin induced decays $B^0 \to ϕK^{*0}$, $B^+ \to ϕK^{*+}$. We study the effect of rescattering mediated by charmed resonances, finding that in $B \to ϕK^*$ it can be responsible of the suppression of the longitudinal amplitude. For the decay $B \to ρK^*$ we find that the longitudinal fraction cannot be too large without invoking new effects.

description: During the first six months of operations, six Gamma Ray Bursts (GRBs) have been detected in the field of view of the INTEGRAL instruments and localized by the INTEGRAL Burst Alert System (IBAS): a software for the automatic search of GRBs and the rapid distribution of their coordinates. I describe the current performances of IBAS and review the main results obtained so far. The coordinates of the latest burst localized by IBAS, GRB 031203, have been distributed within 20 s from the burst onset and with an uncertainty radius of only 2.7 arcmin.

Foreign Direct Investments and trade in agriculture: an incomplete contracts approach

description: Some firms invest abroad in land, while other firms procure raw materials from food or energy importing countries by means of an outsourcing arrangement with farmers in land-abundant countries. Few studies have investigated the pattern of recent Foreign Direct Investment (FDI) in agriculture and the ones that have are mostly focused on the locational drivers of FDI. This paper explores how the contractual features of transactions of agricultural products affect the “internalization” decision of firms, that is, the choice trade/FDI. The paper develops a partial equilibrium model incorporating incomplete contracts and asset specificity, which is used to address a number of questions: What is the impact of the quality of the institutions on the choice trade/FDI? How may the bargaining power of the downstream and upstream firms affect the outcome? How is the choice FDI/trade affected by the presence of a state–owned firm? The model provides some unconventional results, such as the finding that when the investor is private, better institutions may lead firms to choose outsourcing, while weak institutions may be a driver of FDI.

description: Flat bands are an ideal environment to realize unconventional electronic phases. Here, we show that fermionic systems with dissipation governed by a Bloch Lindbladian can realize dispersionless bands for sufficiently strong coupling to an appropriately engineered bath. These flat bands emerge in a "dark space" of the system-environment coupling and are long-lived by virtue of symmetry protection from dissipation. We exhibit the robustness of this mechanism for general one and two band models with and without spin, and discuss conditions for their experimental realization such as in a 2D material on a superconducting substrate.
