Linear and Nonlinear Effects on Connectivity Structure: A Comparison of European Stock Markets

Understanding how crises spread is important for policymak­ers and regulators to take appropriate measures to prevent or contain crisis spread. This paper aims to analyse the synchronisations and financial con­tagion between the capital markets of Austria (ATX), Hungary (BUX), Croa­tia (CROBEX), Serbia (BELEX 15), Russia (IMOEX), Czech Republic (Prague SE PX), Slovenia (SBI TOP), and Poland (WIG) from September 19th, 2017, to Sep­tember 15th, 2022. The results show that during the Tranquil period, there were 23 integrations (out of 49 possibilities), and the markets with the most integrations are the Russian (IMOEX) and Polish (WIG) capital markets, while the Slovenian market (SBI TOP) does not integrate with any market, suggest­ing some isolation from its regional peers. During the 2020 and 2022 Stress events, we can confirm the presence of 45 integrations, with the stock in­dexes ATX, BUX, IMOEX, and SBI TOP being the most integrated markets (7 out of 7 possibilities). These findings are supported by the results of the un­conditional correlations, which show that the coefficients significantly in­creased between the Tranquil and Stress periods. To validate, the Forbes and Rigobon’s t-test shows that we are witnessing the phenomenon of marked contagion in these regional markets, with the exception of the IMO­EX-CROBEX pair. These findings suggest that regional investors operating in these markets may have some challenges in mitigating portfolio risk, with a high probability of possible losses in their portfolios.
Electron elastic scattering and low-frequency bremsstrahlung on A @C 60 : A model static-exchange approximation

Electron elastic-scattering phase shifts and cross sections as well as total cross sections of lowfrequency bremsstrahlung, its angular-asymmetry and polarization parameters upon low-energy electron collision with endohedral fullerenes A@C60 are theoretically scrutinized versus the nature, size and spin of the encapsulated atom A. This is achieved by choosing Ar, Xe, Ba, Cr, Mn, and Eu as the case-study atoms A. The aim is to uncover the variety of effects which might occur in the above processes rather than to make thorough predictions for one particular spectrum. To that end, the study makes use of a simple model static-exchange approximation. There, both the encapsulated atom A and C60 cage are regarded as non-polarizable targets and the C60 cage itself is modeled by an attractive spherical annular-potential well. Calculated results identify the most interesting and/or useful future measurements or more rigorous calculations to perform. PACS numbers: 34.80. Bm, 34.80. Nz
Kinematics and Convergent Tectonics of the Northwestern South American Plate During the Cenozoic

The interaction of the northern Nazca and southwestern Caribbean oceanic plates with northwestern South America (NWSA) and the collision of the Panama‐Choco arc (PCA) have significant implications on the evolution of the northern Andes. Based on a quantitative kinematic reconstruction of the Caribbean and Farallon/Farallon‐derived plates, we reconstructed the subducting geometries beneath NWSA and the PCA accretion to the continent. The persistent northeastward migration of the Caribbean plate relative to NWSA in Cenozoic time caused the continuous northward advance of the Farallon‐Caribbean plate boundary, which in turn resulted in its progressive concave trench bending against NWSA. The increasing complexity during the Paleogene included the onset of Caribbean shallow subduction, the PCA approaching the continent, and the forced shallow Farallon subduction that ended in the fragmentation of the Farallon Plate into the Nazca and Cocos plates and the Coiba and Malpelo microplates by the late Oligocene. The convergence tectonics after late Oligocene comprised the accretional process of the PCA to NWSA, which evolved from subduction erosion of the forearc to collisional tectonics by the middle Miocene, as well as changes of convergence angle and slab dip of the Farallon‐derived plates, and the attachment of the Coiba and Malpelo microplates to the Nazca plate around 9 Ma, resulting in a change of convergence directions. During the Pliocene, the Nazca slab broke at 5.5°N, shaping the modern configuration. Overall, the proposed reconstruction is supported by geophysical data and is well correlated with the magmatic and deformation history of the northern Andes.

We report resolution enhancement for non-linear swept-source lidar sensor using quasi-synchronous resampling, a new post-processing method. We report 6mm Fourier-limited resolution at 6m distance, and improvement of single-target resolution at 6m from 27.9mm to 0.42mm.
Diet of Indus Civilization: Reinterpretations from Multi–Site Stable Isotopic Mortuary Analysis

Several insights on the identification and mobility of the Indus Civilization were provided by previous researchers based on the results limited towards archaeological context. In this study, several such published data of Mortuary samples from the major urban centre of Harappa, the eastern frontier town of Farmana, and the post–urban necropolis at Sanauli are re–evaluated in context with the modern dental samples. The results are compared to the compositional signatures found within teeth from modern humans from the USA, East Asia, Mexico and Bulgaria, which is expected to show variance in their isotopic signature depending upon regional level precipitation and diet. The results from δ18O signatures from the Indus Valley point towards dependence on riverine water for drinking.
The Impact of Animal Disease Outbreaks on China’s Meat Imports

ABSTRACT We assess the effect of three animal disease outbreaks on China’s meat imports from 1992 to 2017, namely foot-and-mouth disease (FMD) for swine, bovine spongiform encephalopathy (BSE) for cattle, and highly pathogenic avian influenza (HPAI) for poultry. Using system-GMM and FGLS estimators, we find that outbreaks of animal diseases in exporting countries reduce China’s import of the meat products. Additionally, we find positive trade diversion and substitution effects in both FMD and HPAI but negative effects in BSE. Although these results indicate that China can accommodate its meat consumption needs through international trade now, we are skeptical that it can continue to do so if animal husbandry practices do not improve in China. This calls for major meat exporters to improve production efficiency and reduce the prevalence of animal diseases. With increasing environmental pressure and high dependency on imported feed caused by the expanding livestock sector, we recommend a sustainable diet by encouraging less consumption of meat.
Going with the crowd in volatile times: Exposure to environmental variability increases people's preference for popular options

More extreme temperature and precipitation events are defining features of climate change, and higher volatility in asset prices is a defining feature of globalization. Four experiments (two preregistered; total N = 2086) found that exposure to a high degree of variability in a given domain shifted people's preferences toward more popular products, that is, products rated by a larger number of consumers. This finding replicated across different experimental manipulations of variability, including graphs depicting either high or low variability in annual rainfall or temperature (Experiments 1 and 2), and in the experienced outcomes of dice rolls, which were manipulated to be perceived as having high or low variability (Experiment 3). The results generalized across different consumer choices, including services (Experiment 1) and products (Experiments 2 and 3). After exposure to higher variability, participants who received a more popular but lower rated option felt less anxious than those who received a less popular but higher rated option, indicating that choosing popular products serves to reduce the anxiety induced by higher variability (Experiment 4). This research highlights both a novel consequence of exposure to greater variability and a novel antecedent of people's preference for popular options.
Effects of strain on electronic properties of Delta nitrogen-doped graphene nanoribbons

ABSTRACT The band structure, electronic structure and density of states of the Delta nitrogen-doped armchair-edge graphene nanoribbons (AGNRs) were investigated under compressive strain by means of an extension of the Extended Hückel method. The results indicate that the Nitrogen-doped graphene nanoribbons (N-AGNRs) system can show a good elastic behavior under 16% compressive strain. Meanwhile, N-AGNRs can maintain the metallic under compressive strain between 0% and 20%. Further analysis suggests that compressive strain induced electronic states nonlocal phenomenon.
CardIAP: calcium transients confocal image analysis tool

One of the main topics of cardiovascular research is the study of calcium (Ca2+) handling, as even small changes in Ca2+ concentration can alter cell functionality (Bers, Annu Rev Physiol, 2014, 76, 107–127). Ionic calcium (Ca2+) plays the role of a second messenger in eukaryotic cells, associated with cellular functions such as cell cycle regulation, transport, motility, gene expression, and regulation. The use of fluorometric techniques in isolated cells loaded with Ca2+-sensitive fluorescent probes allows quantitative measurement of dynamic events occurring in living, functioning cells. The Cardiomyocytes Images Analyzer Python (CardIAP) application addresses the need to analyze and retrieve information from confocal microscopy images systematically, accurately, and rapidly. Here we present CardIAP, an open-source tool developed entirely in Python, freely available and useable in an interactive web application. In addition, CardIAP can be used as a standalone Python library and freely installed via PIP, making it easy to integrate into biomedical imaging pipelines. The images that can be generated in the study of the heart have the particularity of requiring both spatial and temporal analysis. CardIAP aims to open the field of cardiomyocytes and intact hearts image processing. The improvement in the extraction of information from the images will allow optimizing the usage of resources and animals. With CardIAP, users can run the analysis to both, the complete image, and portions of it in an easy way, and replicate it on a series of images. This analysis provides users with information on the spatial and temporal changes in calcium releases and characterizes them. The web application also allows users to extract calcium dynamics data in downloadable tables, simplifying the calculation of alternation and discordance indices and their classification. CardIAP aims to provide a tool that could assist biomedical researchers in studying the underlying mechanisms of anomalous calcium release phenomena.
DMPP-4: Candidate sub-Neptune mass planets orbiting a naked-eye star

We present radial velocity measurements of the very bright (V ∼ 5.7) nearby F star, DMPP-4 (HD 184960). The anomalously low Ca ii H&K emission suggests mass loss from planets orbiting a low activity host star. Periodic radial velocity variability with ∼10 m s−1 amplitude is found to persist over a >4 year timescale. Although the non-simultaneous photometric variability in four tess sectors supports the view of an inactive star, we identify periodic photometric signals and also find spectroscopic evidence for stellar activity. We used a posterior sampling algorithm that includes the number of Keplerian signals, Np, as a free parameter to test and compare (1) purely Keplerian models (2) a Keplerian model with linear activity correlation and (3) Keplerian models with Gaussian processes. A preferred model, with one Keplerian and quasi-periodic Gaussian process indicates a planet with a period of $P_\textrm {b} = 3.4982^{+0.0015}_{-0.0027}$ d and corresponding minimum mass of $m_\textrm {b}\, \textrm {sin}\, i = 12.2^{+1.8}_{-1.9}$ M⊕. Without further high time resolution observations over a longer timescale, we cannot definitively rule out the purely Keplerian model with 2 candidates planets with $P_\textrm {b} = 2.4570^{+0.0026}_{-0.0462}$ d, minimum mass $m_\textrm {b}\, \textrm {sin}\, i = 8.0^{+1.1}_{-1.5}$ M⊕ and $P_\textrm {c} = 5.4196^{+0.6766}_{-0.0030}$ d and corresponding minimum mass of $m_\textrm {b}\, \textrm {sin}\, i = 12.2^{+1.4}_{-1.6}$ M⊕. The candidate planets lie in the region below the lower-envelope of the Neptune Desert. Continued mass loss may originate from the highly irradiated planets or from an as yet undetected body in the system.
Should We Opt for the Black Friday Discounted Price or Wait Until the Boxing Day?

We derive an optimal strategy for minimizing the expected loss in the two-period economy when a pivotal decision needs to be made during the first time period and cannot be subsequently reversed. Our interest in the problem has been motivated by the classical shopper's dilemma during the Black Friday promotion period, and our solution crucially relies on the pioneering work of McDonnell and Abbott on the two-envelope paradox.
Cognitive radio adaptation for power consumption minimization using biogeography-based optimization

Adaptation is one of the key capabilities of cognitive radio, which focuses on how to adjust the radio parameters to optimize the system performance based on the knowledge of the radio environment and its capability and characteristics. In this paper, we consider the cognitive radio adaptation problem for power consumption minimization. The problem is formulated as a constrained power consumption minimization problem, and the biogeography-based optimization (BBO) is introduced to solve this optimization problem. A novel habitat suitability index (HSI) evaluation mechanism is proposed, in which both the power consumption minimization objective and the quality of services (QoS) constraints are taken into account. The results show that under different QoS requirement settings corresponding to different types of services, the algorithm can minimize power consumption while still maintaining the QoS requirements. Comparison with particle swarm optimization (PSO) and cat swarm optimization (CSO) reveals that BBO works better, especially at the early stage of the search, which means that the BBO is a better choice for real-time applications.
Functionalized Copper Phthalocyanine and Zinc Phthalocyanine as a Coating Layer on the Sensitivity of QCM-Based VOCs Sensor

The sensitivity of a QCM-based VOCs sensor with two kinds of a metal phthalocyanine, i.e., copper phthalocyanine (CuPc) and zinc phthalocyanine (ZnPc) was examined for various VOCs. The sensitivity of the two metal phthalocyanine was determined by the compatibility of the overlapped metal orbitals (Cu(II) dan Zn(II)) and the corresponding VOCs. The CuPc and the ZnPc layer were deposited on the quartz crystal oscillator by a vacuum evaporation method. The frequency shift and the sensitivity of the sensors with the two functional layers were tested using 5 VOCs: formaldehyde, propanol, ethanol, toluene, and ketone. The CuPc sensor showed the highest sensitivity to formaldehyde. On the other hand, the ZnPc was highly sensitive to ethanol.
Hydro-acoustic and noise analysis of DTMB4119 marine propeller at different advance coefficients using DES turbulence model

Investigating the Hydro-acoustic behaviour and noise of marine propellers is very important, especially in underwater vessels and submarines. The present study aims to numerically model the hydrodynamic noise of a benchmark marine propeller using the computational fluid dynamics method based on the finite volume method under open water conditions. The DES turbulence model is used in the numerical simulation, which is a good model for modelling small eddies near the wall and covers the advantages of both LES and RANS models. To increase the accuracy of the numerical solution, a finer grid has been used on the blades tips, hub, and boss. According to the investigations, time step independence occurs for 0.001 s. In the following, the numerical analysis of the hydrodynamic noise of the DTMB4119 propeller has been extracted at the advance coefficients of 0.5–1.1 and distances of 1D to 10D from the propeller in the axial directions and perpendicular to the fluid flow. Based on the obtained results, the highest level of noise emission in the flow direction is related to low frequencies, and with the increase in frequency and distance from the noise source, the emitted noise level decreases. Increasing the distance from the noise source from 1D to 10D decreases the emitted noise level by 40 dB. For every 0.1 reduction in the advance coefficient, 10 dB is added to the noise emission level in the axial direction.
Transcranial electrical stimulation of the prefrontal cortex to boost the hypnosis experience: who benefits most?

Many attempts have been made to enhance hypnotizability. The most recent studies adopted the non-invasive brain stimulation to deactivate the dorsolateral prefrontal cortex (DLPFC) during hypnosis, indicating this as a promising approach. However, it is still no clear whether individual factors can predict the effects of stimulation on hypnotizability. In the present study we adopted the phenomenological consciousness inventory (PCI) to retrospectively assess the mental processes during hypnosis and to predict hypnotizability, here defined as “hypnoidal state. ” The aim was to investigate the possible role of the hypnotic susceptibility on the efficacy of a validated approach of hypnosis enhancement through cathodal transcranial electrical stimulation (tDCS) of the left DLPFC. Results indicated that the lower hypnoidal state at baseline predicted the greater enhancement after the active tDCS. These findings suggest the subjects with lower hypnotic responsiveness as the best candidates for the tDCS interventions of hypnosis enhancement, at least for the montage targeting the left DLPFC. Neurocognitive underpinnings and clinical implications of the results are discussed.
Removal of lead metal from groundwater using graphene oxide nanosheet functionalized with ethylene diamine tera-acetic acid

One of the important carbon materials, graphene oxide (GO), has several oxygen-containing functional groups in the form of epoxy, hydroxyl, and carboxyl on its basal plane and its edges. Due to its unique structure, it has attracted increasing interest in multidisciplinary studies of physical and chemical attributes. GO-based compounds in particular are potential for environmental uses in energy and clean-up. In the present work, GO was functionalized with ethylenediaminetetraacetic acid (EDTA) to remove lead ions from water. The as-prepared and EDTA functionalized GO were applied as adsorbents to remove Pb(II) from groundwater in Western El-Mina area, mid Upper Egypt. The adsorption of lead under effects of contact time, temperature and pH has been investigated. It is concluded that the maximum adsorption capacity of pure GO for the lead was about 246 mg/g while that of GO-EDTA was about 360 mg/g. It is indicated that pH~6 and temperature ~40°C are the best conditions for Pb(II) removal from water. The adsorption experimental data was evaluated through elucidating the adsorption kinetic using pseudo-first-order and pseudo-second-order. It is revealed that the pseudo-second-order model is the best representing adsorption kinetics model for both GO and GO-EDTA. Additionally, the equilibrium adsorption isotherm has been studied using the Langmuir and Freundlich isotherms models. The adsorption equilibrium isotherms data followed the Langmuir model better than the Freundlich model. The present work indicated that the prepared materials (GO and GO-EDTA) are efficient adsorbents for lead removal.
Computationally Efficient Markov Chain Monte Carlo Methods for Hierarchical Bayesian Inverse Problems

In Bayesian inverse problems, the posterior distribution can be used to quantify uncertainty about the reconstructed solution. In practice, approximating the posterior requires Markov chain Monte Carlo (MCMC) algorithms, but these can be computationally expensive. We present a computationally efficient MCMC sampling scheme for ill-posed Bayesian inverse problems. The forward map is assumed to be linear with additive Gaussian noise, and the goal is to reconstruct the solution as well as to estimate regularization parameters. We employ a Metropolis-Hastings-within-Gibbs (MHwG) sampler with a proposal distribution based on a low-rank approximation of the prior-preconditioned Hessian. We show the dependence of the acceptance rate on the number of eigenvalues retained and discuss conditions under which the acceptance rate is high. We demonstrate our proposed sampler through numerical experiments in electroencephalography and computerized tomography.

Estimation of urban noise with the assimilation of observations crowdsensed by the mobile application Ambiciti

We investigated the estimation of urban noise by merging simulated noise maps and observations collected by the mobile application Ambiciti. Both the simulated noise map and the mobile observations are subject to uncertainties that are taken into account in the merging. Large errors in the mobile observations are due to the microphone inaccuracies, the processing of the mobile operating system, the GPS location errors and the lack of temporal representativeness of the measurements. We will explain how the variances of these errors can be quantified, so that the total observational error variance can be computed. We will also introduce a model for the error covariances in the simulated noise map, which takes into account the streets geometry. Using these error covariances, we computed the so-called best linear unbiased estimator (BLUE), which is a classical estimator in data assimilation techniques. This estimator produces an analysis noise map from the background (simulated) noise map and the mobile observations, so that the variance of the analysis error is minimized. A posteriori statistical tests were carried out in order to check for the consistency of the various error variances. The analysis was also evaluated using cross-validation and accurate observations from a sound level meter.
