description: With the introduction of Navigation Message Authentication (NMA), future Global Navigation Satellite Systems (GNSSs) prevent spoofing by simulation, i.e., the generation of forged satellite signals based on public information. However, authentication does not prevent record-and-replay attacks, commonly termed as meaconing. These attacks are less powerful in terms of adversarial control over the victim receiver location and time, but by acting at the signal level, they are not thwarted by NMA. This makes replaying/relaying attacks a significant threat for GNSS. While there are numerous investigations on meaconing, the majority does not rely on actual implementation and experimental evaluation in real-world settings. In this work, we contribute to the improvement of the experimental understanding of meaconing attacks. We design and implement a system capable of real-time, distributed, and mobile meaconing, built with off-the-shelf hardware. We extend from basic distributed attacks, with signals from different locations relayed over the Internet and replayed within range of the victim receiver(s): this has high bandwidth requirements and thus depends on the quality of service of the available network to work. To overcome this limitation, we propose to replay on message level, including the authentication part of the payload. The resultant reduced bandwidth enables the attacker to operate in mobile scenarios, as well as to replay signals from multiple GNSS constellations and/or bands simultaneously. Additionally, the attacker can delay individually selected satellite signals to potentially influence the victim position and time solution in a more fine-grained manner. Our versatile test-bench, enabling different types of replaying/relaying attacks, facilitates testing realistic scenarios towards new and improved replaying/relaying-focused countermeasures in GNSS receivers.

description: By developing a `two-crystal' method for color erasure, we can broaden the scope of chromatic interferometry to include optical photons whose frequency difference falls outside of the 400 nm to 4500 nm wavelength range, which is the passband of a PPLN crystal. We demonstrate this possibility experimentally, by observing interference patterns between sources at 1064.4 nm and 1063.6 nm, corresponding to a frequency difference of about 200 GHz.

description: We characterize quasi Kähler manifolds whose curvature tensor associated to the canonical Hermitian connection satisfies the first Bianchi identity. This condition is related with the third Gray identity and in the almost Kähler case implies the integrability. Our main tool is the existence of generalized holomorphic frames introduced by the second author previously. By using such frames we also give a simpler and shorter proof of a Theorem of Goldberg. Furthermore we study almost Hermitian structures having the curvature tensor associated to the canonical Hermitian connection equal to zero. We show some explicit examples of quasi Kähler structures on the Iwasawa manifold having the Hermitian curvature vanishing and the Riemann curvature tensor satisfying the second Gray identity.

description: The Optical Monitoring Camera (OMC) has been observing the optical emission from the prime targets of the gamma-ray instruments on-board the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) since its launch on 17 October 2002. Simultaneously to these observations of the prime targets, the OMC has been acquiring data from about 100 objects of interest within its 5ºx5º field of view of each exposure, mainly optically variable or suspected variable sources. The analysis of these complementary observations has led to many interesting scientific results. After 21 years of INTEGRAL/OMC observations, the OMC Archive, publicly available at http://sdc.cab.inta-csic.es/omc/, contains the light curves of about 105 000 scientific objects with more than 50 photometric points. Furthermore, in 2012 we published the first INTEGRAL/OMC catalogue of variable sources, where we provided a compilation of clean and ready-to-use OMC light curves of a selected sample, together with some useful information on the variability and periodicity of these sources.

In this contribution we summarise the present contents of the OMC Archive and review some of the most interesting results on OMC complementary science using data from the OMC Archive and/or the first INTEGRAL/OMC catalogue, obtained by the scientific community so far for different types of variable sources.

description: Abstract

Sports Authority of India (SAI) is an organization responsible for sports promotion throughout India. E-governance initiatives in SAI started in 2014 with the creation of its website. In this paper, the focus would be on examining how websites help in creating an online identity of SAI and its users. For analyzing the issue in detail, Actor Network Theory (ANT) has been chosen. ANT recognizes the importance of interaction between technological and social actors and the process that mutually shapes the two. It takes into consideration how actors are enrolled in a network, and how these actors combine to form a whole network and achieve its stability. The primary aim of this paper is to stress the role of websites in developing user-administrator interactions.
Complementarity of Process and Substance

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Process Philosophy endeavours to replace the classical ontology of substances by a process ontology centered on notions of changes and transitions. We argue, that the substantial and processual approach are mutually complementary. Here, complementarity is to be understood in the sense of a "Generalized Quantum Theory", which is not restricted to physical phenomena. From this point of view, restricting oneself to either substance or process ontology would be as ill-advised as exclusively relying on position or momentum observables in physics. A new view on Zeno's paradox lends itself. The meaning of an "internal energy observable", complementary to inner time, and its relationship to "akategorial states" of the human mind will also be discussed.

Second-harmony generation studies of organic salts
Creators: name: Patrick, Brian Olivier
Publisher: name: University of British Columbia
Year: 2009

description: [Chemical model] Second-harmonic generation (SHG) in the solid-state is restricted to materials that crystallize in non-centrosymmetric space groups. Unfortunately, the vast majority of solids crystallize in centrosymmetric space groups and are therefore SHG-inactive. The requirement for solid-state asymmetry is addressed in two series of salts. Acid (1), SHG-inactive due to its centrosymmetric (P1) packing, was coupled to six optically pure amines to form salts and/or complexes that, by virtue of their chiral counterion, crystallized in non-centrosymmetric space groups. The 1064 nm output from a Nd:YAG laser produced 532 nm SHG from each of the six salts, with three of the salts producing SHG-intensities at least an order of magnitude greater than that of our standard, urea. X-ray crystallographic analysis was carried out on five of the six salts, and an attempt was made to rationalize each salt's SHG-intensity based on the orientation of its molecular charge-transfer axis in the unit cell and on its chromophore density. A second series of salts and/or complexes was formed by coupling acid (2) to the same set of optically pure amines as were used in the first series. The second electron-withdrawing group in (2) permits additional directions of charge-transfer, rather than the unidirectional charge-transfer along the para amine-nitro axis of (1). As such, the macroscopic second-order susceptibilities of salts made from (2) depend on the orientations of the aromatic ring as a whole and not simply the above-mentioned chargetransfer axis. Once again, the parent acid of the series of salts crystallized in a centrosymmetric space group {P2\lc) and was SHG-inactive, while each of the six salts produced varied amounts of SHG. While none of the salts formed from (2) produce SHG with the same intensity as the best of the salts formed from acid (1), four of the six salts produced SHG-intensities that were at least twice that of urea. X-ray crystallographic analysis was carried out on each of the salts and an attempt was once again made to rationalize the SHG-intensities measured from each salt, this time based on the orientations of the respective aromatic rings and on the different chromophore densities. The SHG-intensities of the salts and complexes formed in the first two series appear to be limited, in part, by the decrease in NLO chromophore density produced by the salt formation. A means of increasing the chromophore density was achieved in a third series of salts, where acids (1) and (2) were coupled to amines (3) and (4). While the chromophore densities of the salts were indeed greater relative to those found in the first two series of materials, the salts were no longer constrained to pack in noncentrosymmetric space groups due to absence of optical purity in any of the acids or bases. As a result, none of the salts packed in non-centrosymmetric space groups and thus each salt was SHG-inactive.
Could dark matter or neutrinos discriminate between the enantiomers of a chiral molecule?

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We examine the effect of cold dark matter on the discrimination between the two enantiomers of a chiral molecule. We estimate the energy difference between the two enantiomers due to the interaction between fermionic WIMPs (weak interacting massive particles) and molecular electrons on the basis that electrons have opposite helicities in opposite enantiomers. It is found that this energy difference is completely negligible. Dark matter could then be discarded as an inductor of chiroselection between enantiomers and then of biological homochirality. However, the effect of cosmological neutrinos, revisited with the currently accepted neutrino density, would reach, in the most favorable case, an upper bound of the same order of magnitude as the energy difference obtained from the well known electroweak electron-nucleus interaction in some molecules.

description: Cultural research is dedicated to understanding the processes of knowledge dissemination and the social and technological practices in the book industry. Research on children books in the 19th century can be supported by computer systems. Specifically, the advances in digital image processing seem to offer great opportunities for analyzing and quantifying the visual components in the books. The production technology for illustrations in books in the 19th century was characterized by a shift from wood or copper engraving to lithography. We report classification experiments which intend to classify images based on the production technology. For a classification task that is also difficult for humans, the classification quality reaches only around 70%. We analyze some further error sources and identify reasons for the low performance.

description: We investigate the ground state of the system of N bosons enclosed in a hard-wall trap interacting via a repulsive or attractive $δ$-function potential. Based on the Bethe ansatz method, the explicit ground state wave function is derived and the corresponding Bethe ansatz equations are solved numerically for the full physical regime from the Tonks limit to the strongly attractive limit. It is shown that the solution takes different form in different regime. We also evaluate the one body density matrix and second-order correlation function of the ground state for finite systems. In the Tonks limit the density profiles display the Fermi-like behavior, while in the strongly attractive limit the Bosons form a bound state of N atoms corresponding to the N-string solution. The density profiles show the continuous crossover behavior in the entire regime. Further the correlation function indicates that the Bose atoms bunch closer as the interaction constant decreases.

description: We develop some properties of the non-BPS attractive STU black hole. Our principle result is the construction of exact solutions for the moduli, the metric and the vectors in terms of appropriate harmonic functions. In addition, we find a spherically-symmetric attractor carrying $p^0$ ($D6$ brane) and $q_a$ ($D2$ brane) charges by solving the non-BPS attractor equation (which we present in a particularly compact form) and by minimizing an effective black hole potential. Finally, we make an argument for the existence of multi-center attractors and conjecture that if such solutions exist they may provide a resolution to the existence of apparently unstable non-BPS ``attractors.''

Diagnosis
Diameter 1.41–1.87 mm, 41–48 podous rings (Fig. 9). Shares a short (as broad as long, or slightly longer) gonopodal palette with A. claudiahempae, A. denticulatus, A. fasciatus, A. stereosathe and A. udzungwensis. Differs from these species by the combination of fully developed telopodites on the first pair of male legs, the gonopodal telomere describing a ca 270° curve, curving almost in one plane only, by lacking a spinose lid-like flap on the besal telomeral lamella and by lacking a distinct mesobasal lobe of the gonopod palette.

Descriptive notes
The newly studied specimens from Kidatu are considerably smaller than those from Mwanihana FR; see Table 1.
First pair of male legs (Figs 7 A–C): prefemoral processes finger-shaped; setae of telopodite distal to prefemur same length as setae of normal walking legs.
Gonopod telopodite (Fig. 16): basal telomeral lamella (btl) forming a subspherical chamber but without a spinose lid-like flap, cf. A. udzungwensis. In the specimen illustrated in Fig. 16 the tip has remarkably long marginal laciniae, approaching the condition typical of A. stereosathe (Enghoff & Frederiksen 2015: fig. 9c).
Remarks
The distinction between A. submajor and A. udzungwensis is discussed under the latter species.

“Should I stay or should I go?”: Weather forecasts and the economics of “short breaks”
Creators: name: Zirulia, Lorenzo

Subjects: SECS-P/01 Economia politica

description: The aim of this paper is to model the decisions of tourists and a monopolist firm when weather forecasts are available. Before deciding whether to go on holiday or not, but after the firm has decided and posted its price, tourists can look at weather forecasts. Our results show that the price chosen by the firm and the corresponding equilibrium profit are decreasing as a function of the accuracy of weather forecasts. Consumers, instead, are better off the more accurate weather forecasts become. Managerial and policy implications are also derived.

description: One of the major problems in quantum physics has been to generalize the classical root-mean-square error to quantum measurements to obtain an error measure satisfying both soundness (to vanish for any accurate measurements) and completeness (to vanish only for accurate measurements). A noise-operator based error measure has been commonly used for this purpose, but it has turned out incomplete. Recently, Ozawa proposed a new definition for a noise-operator based error measure to be both sound and complete. Here, we present a neutron optical demonstration for the completeness of the new error measure for both projective (or sharp) as well as generalized (or unsharp) measurements.

description: Abstract

The COVID-19 pandemic catalyzed rapid adoption of telehealth services across the healthcare industry. This study investigates the effects of telehealth integration on revenue cycle management (RCM) during the pandemic and in its aftermath. Through a comprehensive analysis of financial data from 500 healthcare providers across the United States, we examine changes in key RCM metrics, including days in accounts receivable, claim denial rates, and overall revenue. Our findings indicate that while telehealth adoption initially presented challenges for RCM processes, healthcare providers who successfully integrated telehealth services experienced improved financial outcomes in the long term. This research provides valuable insights for healthcare administrators and policymakers on optimizing RCM strategies in an increasingly digital healthcare landscape.

description: Inspection in confined spaces and difficult-to-access machines is a challenging quality assurance task and particularly difficult to quantify and automate. Using the example of aero engine inspection, an approach for the high-precision inspection of movable turbine blades in confined spaces will be demonstrated. To assess the condition and damages of turbine blades, a borescopic inspection approach in which the pose of the turbine blades is estimated on the basis of measured point clouds is presented. By means of a feature extraction approach, film-cooling holes are identified and used to pre-align the measured point clouds to a reference geometry. Based on the segmented features of the measurement and reference geometry a RANSAC-based feature matching is applied, and a multi-stage registration process is performed. Subsequently, an initial damage assessment of the turbine blades is derived, and engine disassembly decisions can be assisted by metric geometry deviations. During engine disassembly, the blade root is exposed to high disassembly forces, which can damage the blade root and is crucial for possible repair. To check for dismantling damage, a fast inspection of the blade root is executed using the borescopic sensor.

description: We find exact cosmological solutions when the Newton parameter and the cosmological term are dynamically evolving in a renormalization-group improved Hamiltonian approach. In our derivation we use the Noether symmetry approach, leading to an interesting variable transformation which yields exact and general integration of the cosmological equations. The functional dependence of Lambda on G is determined by the method itself, therefore generalizing previous results on symmetry principles in cosmology. We find new functional relations between Lambda and G, jointly with power-law inflation for pure gravity.

On the mass and metallicity distribution of parent AGB stars of presolar SiC

description: The vast majority (>=90%) of presolar SiC grains identified in primitive meteorites are relics of ancient asymptotic giant branch (AGB) stars, whose ejecta were incorporated into the Solar System during its formation. Detailed characterization of these ancient stardust grains has revealed precious information on mixing processes in AGB interiors in great detail. However, the mass and metallicity distribution of their parent stars still remains ambiguous, although such information is crucial to investigating the slow neutron capture process, whose efficiency is mass- and metallicity-dependent. Using a well-known Milky Way chemo-dynamical model, we follow the evolution of the AGB stars that polluted the Solar System at 4.57 Gyr ago and weighted the stars based on their SiC dust productions. We find that presolar SiC in the Solar System predominantly originated from AGB stars with M~2 Msun and Z~Zsun. Our finding well explains the grain-size distribution of presolar SiC identified in situ in primitive meteorites. Moreover, it provides complementary results to very recent papers dealing with the characterization of parent stars of presolar SiC.

description: Throughout the last decade, digitalization has fundamentally transformed the business world and
put into question traditional strategy wisdom. As (digital) information technologies (IT) are the
drivers of this transformation, we can expect it to have an even more profound influence on IT/IS
strategy thinking. While several scholars have acknowledged the fundamental changes induced
by digitalization on the conceptual level, research on emerging IT/IS strategy contents is still
missing. This paper intends to fill this gap by revealing both practically relevant and theoretically
valid concerns worth considering when developing IT/IS strategies for/in the digital age. Based
on a working definition of digitalization, we present a set of hypotheses on how IT/IS strategies
might respond to trends in digitalization. We also put these hypotheses to discussion in ten
interviews with IT/IS managers in practice. Our research adds to a better understanding of the
complex phenomenon of digitalization and its implications for IT/IS strategy development. Our
research responds to calls for a stronger focus on strategy contents and more practice-oriented
IT/IS strategy research.

Architectures of epidemic models: accommodating constraints from empirical and clinical data

description: Deterministic compartmental models have been used extensively in modeling epidemic propagation. These models are required to fit available data and numerical procedures are often implemented to this end. But not every model architecture is able to fit the data because the structure of the model imposes hard constraints on the solutions. We investigate in this work two such situations: first the distribution of transition times from a compartment to another may impose a variable number of intermediary states; secondly, a non-linear relationship between time-dependent measures of compartments sizes may indicate the need for structurations (i.e., considering several groups of individuals of heterogeneous characteristics).

description: We predict the stability of a new extended two-dimensional hydrocarbon on the basis of first-principles total energy calculations. The compound that we call graphane is a fully saturated hydrocarbon derived from a single graphene sheet with formula CH. All of the carbon atoms are in sp3 hybridization forming a hexagonal network and the hydrogen atoms are bonded to carbon on both sides of the plane in an alternating manner. Graphane is predicted to be stable with a binding energy comparable to other hydrocarbons such as benzene, cyclohexane, and polyethylene. We discuss possible routes for synthesizing graphane and potential applications as a hydrogen storage material and in two dimensional electronics.

description: As the use of Internet of Things (IoT) devices for monitoring purposes becomes ubiquitous, the efficiency of sensor communication is a major issue for the modern Internet. Channel coding is less efficient for extremely short packets, and traditional techniques that rely on source compression require extensive signaling or pre-existing knowledge of the source dynamics. In this work, we propose an encoding and decoding scheme that learns source dynamics online using a Hidden Markov Model (HMM), puncturing a short packet code to outperform existing compression-based approaches. Our approach shows significant performance improvements for sources that are highly correlated in time, with no additional complexity on the sender side.

Potential Analysis for Hypoelliptic Second Order PDEs with Nonnegative Characteristic Form
Creators: name: Abbondanza, Beatrice <1986>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2015
Subjects: MAT/05 Analisi matematica

description: In this Thesis we consider a class of second order partial differential operators with non-negative characteristic form and with smooth coefficients. Main assumptions on the relevant operators are hypoellipticity and existence of a well-behaved global fundamental solution.
We first make a deep analysis of the L-Green function for arbitrary open sets and of its applications to the Representation Theorems of Riesz-type for L-subharmonic  and L-superharmonic functions. Then, we prove an Inverse Mean value Theorem characterizing the superlevel sets of the fundamental solution by means of L-harmonic functions. Furthermore, we establish a Lebesgue-type result showing the role of the mean-integal operator in solving the homogeneus Dirichlet problem related to L in the Perron-Wiener  sense. Finally, we compare Perron-Wiener and weak variational solutions of the homogeneous Dirichlet problem, under specific hypothesis on the boundary datum.

description: Swarm robot systems, which consist of many cooperating mobile robots, have attracted attention for their environmental adaptability and fault tolerance advantages. One of the most important tasks for such systems is coverage control, in which robots autonomously deploy to approximate a given spatial distribution. In this study, we formulate a coverage control paradigm using the concept of optimal transport and propose a novel control technique, which we have termed the optimal transport-based coverage control (OTCC) method. The proposed OTCC, derived via the gradient flow of the cost function in the Kantorovich dual problem, is shown to covers a widely used existing control method as a special case. We also perform a Lyapunov stability analysis of the controlled system, and provide numerical calculations to show that the OTCC reproduces target distributions with better performance than the existing control method.
