How to Obtain Consumer Information in Tourism e-Commerce? An Exploratory Research Based on Tourism Live Broadcasting on Location

As a communication and marketing channel of e-commerce, the atmosphere in live broadcasting has an important impact on consumer behavior intention. It is urgent to strengthen the research on the cues of live broadcasting environment atmosphere for the improvement of the new marketing mode of tourism live broadcasting on location in the rapid development. Through unstructured in-depth interviews, this paper applies grounded theory to explore the deep-seated factors that affect the behavior intention in tourism live broadcasting on location. This study found that atmosphere cues, online trust, consistency of anchor image and content all affect consumer behavior intention, but the influence path is not consistent. Atmosphere cues are the antecedents, which play a mediating role in the impact of online trust on behavior intention, and consistency of anchor image and content has a moderating effect on Online trust. On this basis, this study explores the constituent factors of the above three main categories and the mechanism model of their action on behavioral intention, namely the "atmosphere cognition behavior" integrated model, which provides ideas for the marketing mode of tourism live broadcasting on location to play a better role in effectively disseminating information, enhancing interaction and promoting tourism behavioral decision-making.

Distributed unmanned combat is a new combat style shaping future information warfare, for which network communication is crucial. This study constructed the star network topology of LTE-based distributed unmanned combat platform against the background of using distributed unmanned combat vehicles in future combat. The network performances of the distributed unmanned combat vehicle and LTE wireless base station communication under the star topology are simulated and analyzed using the discrete-event network simulator NS3. The results show that the star structure is adaptable in the LTE network; the uplink and downlink performance indicators of the distributed unmanned combat vehicles and LTE wireless base station reach a high level; and the data can be transmitted effectively.
Distributed Publish/Subscribe Protocol with Minimum Number of Encryption

Publish/subscribe is a scalable communication method for one-to-many communications. Centralized Pub/Sub protocols rely on a centralized broker that is a trusted third party managing the subscriptions. To prevent data alteration by the broker, or by an entity outside of the system, the literature proposes E2E security solutions. The issue with this solution is that they all introduce a third party who is hardly trustable in practice. Recently, Pub/Sub protocols have been proposed using the blockchain to manage the subscriptions and provable data deliveries. In this paper, we focus our work on one publish/subscribe protocol, called SUPRA, that uses the blockchain only when necessary. We explain why the current version of the protocol does not respect the publish/subscribe paradigm because a subscriber has to encrypt and sign each data as many times as there are subscribers. Then, present how to update the protocol in order for each data to be encrypted and signed only once, regardless of the number of subscribers, while keeping the security properties of the protocol. The result is a publish/subscribe protocol with strong delivery guarantees and traceability that can be used to share sensitive data.
Wind tunnel test on wind turbine airfoil with adaptive trailing edge geometry

,A wind tunnel test of the wind turbine airfoil Ris oe-B1-18 airfoil equipped with an Adaptive Trailing Edge Geometry (ATEG) was carried out. The ATEG was made by piezo electric actuators attached to the trailing edge of a non-deformable airfoil and controlled by an amplifier. The airfoil was tested at Re = 1.66x10 6 . Steady state and dynamic tests were carried out with prescribed deflections of the ATEG. The steady state tests showed that deflecting the ATEG towards the pressure side (posi tive β) translated the lift curve to higher lift values and deflecting the ATEG towards the suc tion side (negative β β β β) translated the lift curve to lower lift values. Furthermore, cd was almost unaffected by the ATEG actuation. Testing the airfoil for a step change of the ATEG f rom β=-3.0 to +1.8 showed that the obtainable Δcl was 0.10 to 0.13 in the linear part of the lift cu rve. Modeling the step response with an indicial function formulation showed that t he time constant in the step change and in sinusoidal deflections in dimensionless terms was T0* =0.6. Testing the ability of the ATEG to cancel out the load variations for an airfoil in si nusoidal pitch motion showed that it was possible to reduce the amplitude with around 80% from Δ Δ Δ Δcl=0.148 to Δcl=0.032.
A Multi-objective Response Surface Analysis for the Determination of the Optimal Cut-off Quality and Minimum Thickness for Selective Mining of Multiple-layered Lignite Deposits

For the estimation of grade and tonnage of the multiple-layer lignite deposits a sophisticated evaluation methodology, based on exploitation and quality parameters, is used. These parameters are usually determined empirically and the selected values are not always optimal. For the estimation of the optimal values, a new methodology based on response surface analysis is suggested. The minimum thicknesses for selective excavation of lignite and waste layers, as well as the maximum allowable ash of the mined lignite, were considered as the decisive control parameters, while the recovery of the lignite, the ash of the mined lignite, and the number of the exploitable lignite blocks were selected as the response variables. The developed methodology was applied in the South Field lignite mine in the area of Ptolemais. The estimated optimal values were compared to those currently applied and their impacts to deposit recovery, equipment utilization, and to the quality of the mined lignite were examined.
Impact of Investment, Financial and Trade Freedom on Bank’s Risk-Taking

Abstract This study explores the impact of investment, financial, and trade freedom on banks' risk-taking and stability of US banks by employing two-step system GMM approach over the extended period from 2002 to 2018. The findings provide evidence that financial freedom decreases risk-taking, while investment and trade freedom increase US larger banks' risk-taking. The results show that investment and trade freedom is beneficial for the stability of banks in the US. The heterogeneity in results indicates that financial freedom reduces the risk-taking, whereas trade and investment freedom increase the risk-taking of well-capitalized and high liquid banks. In contrast, in the case of undercapitalized and low liquid banks, the impact of financial, trade, and investment freedom on risk-taking is insignificant. The result demonstrates that the government's intervention is decisive in developing the degree of economic freedom for the financial system's stability. The finding of the study has practical implications for banks manager, regulators, and policymakers.
ATLIGATOR: editing protein interactions with an atlas-based approach

Motivation Recognition of specific molecules by proteins is a fundamental cellular mechanism and relevant for many applications. Being able to modify binding is a key interest and can be achieved by repurposing established interaction motifs. We were specifically interested in a methodology for the design of peptide binding modules. By leveraging interaction data from known protein structures, we plan to accelerate the design of novel protein or peptide binders. Results We developed ATLIGATOR – a computational method to support the analysis and design of a protein’s interaction with a single side chain. Our program enables the building of interaction atlases based on structures from the PDB. From these atlases pocket definitions are extracted that can be searched for frequent interactions. These searches can reveal similarities in unrelated proteins as we show here for one example. Such frequent interactions can then be grafted onto a new protein scaffold as a starting point of the design process. The ATLIGATOR tool is made accessible through a python API as well as a CLI with python scripts. Availability and Implementation Source code can be downloaded at github (https://www.github.com/Hoecker-Lab/atligator), installed from PyPI (“atligator”) and is implemented in Python 3.
A horizon for haptic perception

The spatial limits of sensory acquisition (its sensory horizon) is a fundamental property of any sensorimotor system. In the present study, we sought to determine the sensory horizon for the human haptic modality. At first blush, it seems obvious that the haptic system is bounded by the space where the body can interact with the environment (e.g., the arm span). However, the human somatosensory system is exquisitely tuned to sensing with tools—blind-cane navigation being a classic example of this. The horizon of haptic perception therefore extends beyond body space, but to what extent is unknown. We first used neuromechanical modelling to determine the theoretical horizon, which we pinpointed as six meters. We then used a psychophysical localization paradigm to behaviorally confirm that humans can haptically localize objects using a six-meter rod. This finding underscores the incredibly flexibility of the brain’s sensorimotor representations, as they can be adapted to sense with an object many times longer than the user’s own body.
The Effects of Electroencephalogram Feature-Based Transcranial Alternating Current Stimulation on Working Memory and Electrophysiology

Transcranial alternating current stimulation (tACS) can influence cognitive functions by modulating brain oscillations. However, results regarding the effectiveness of tACS in regulating cognitive performance have been inconsistent. In the present study, we aimed to find EEG characteristics associated with the improvements in working memory performance, to select tACS stimulus targets and frequency based on this feature, and to explore effects of selected stimulus on verbal working memory. To achieve this goal, we first investigated the EEG characteristics associated with improvements in working memory performance with the aid of EEG analyses and machine learning techniques. These analyses suggested that 8 Hz activity in the prefrontal region was related to accuracy in the verbal working memory task. The tACS stimulus target and pattern were then selected based on the EEG feature. Finally, the selected tACS frequency (8 Hz tACS in the prefrontal region) was applied to modulate working memory. The performance of working memory was improved significantly using the selected stimulation than using 40 Hz and sham stimulation (Especially for participants with low verbal working memory). In conclusion, using EEG features related to positive behavioral changes to select brain regions and stimulation patterns for tACS is an effective intervention for improving working memory. Our results contribute to the groundwork for future tACS closed-loop interventions for cognitive deterioration.
In-Cloud Ice Accretion Modeling on Wind Turbine Blades Using an Extended Messinger Model

Wind turbines operating under cold weather conditions may accumulate ice on its blades. Icing causes the blade sections to stall prematurely reducing the power production at a given wind speed. The unsteady aerodynamic loads associated with icing can accelerate blade structural fatigue and creates safety concerns. In this work, the combined blade element-momentum theory is used to compute the air loads on the baseline rotor blades, prior to icing. At each blade section, a Lagrangian particle trajectory model is used to model the water droplet trajectories and their impact on the blade surface. The extended Messinger model is next used to solve the conservation of mass, momentum, and energy equations in the boundary layer over the surface, and to determine ice accretion rate. The 2-D ice shapes obtained are compared against experimental data at several representative atmospheric conditions with acceptable agreement. The performance of a generic experimental wind turbine rotor exposed to icing climate is simulated to obtain the power loss and identify the critical locations on the blade. The results suggest the outboard of the blade is more prone to ice accumulation causing considerable loss of lift at these sections. Iced formed on the leading edge strongly influences the flow resulting in an early separation over the upper surface. Also, for a tapered and twisted blade, the blades operating at a higher pitch are expected to accumulate more ice. The loss in power ranges from 10% to 50% of the rated power for different pitch settings under the same operating conditions.
Karyotype Differentiation in Cultivated Chickpea Revealed by Oligopainting Fluorescence in situ Hybridization

Chickpea (Cicer arietinum L.) is one of the main sources of plant proteins in the Indian subcontinent and West Asia, where two different morphotypes, desi and kabuli, are grown. Despite the progress in genome mapping and sequencing, the knowledge of the chickpea genome at the chromosomal level, including the long-range molecular chromosome organization, is limited. Earlier cytogenetic studies in chickpea suffered from a limited number of cytogenetic landmarks and did not permit to identify individual chromosomes in the metaphase spreads or to anchor pseudomolecules to chromosomes in situ. In this study, we developed a system for fast molecular karyotyping for both morphotypes of cultivated chickpea. We demonstrate that even draft genome sequences are adequate to develop oligo-fluorescence in situ hybridization (FISH) barcodes for the identification of chromosomes and comparative analysis among closely related chickpea genotypes. Our results show the potential of oligo-FISH barcoding for the identification of structural changes in chromosomes, which accompanied genome diversification among chickpea cultivars. Moreover, oligo-FISH barcoding in chickpea pointed out some problematic, most probably wrongly assembled regions of the pseudomolecules of both kabuli and desi reference genomes. Thus, oligo-FISH appears as a powerful tool not only for comparative karyotyping but also for the validation of genome assemblies.
Resveratrol Relaxes Human Gastric Smooth Muscles Through High Conductance Calcium-Activated Potassium Channel in a Nitric Oxide-independent Manner

Resveratrol, as a polyphenolic compound that can be isolated from plants, and also a component of red wine has broad beneficial pharmacological properties. The aim was to investigate the role of nitric oxide and potassium channels in resveratrol-induced relaxation of human gastric smooth muscle. Gastric tissues were obtained from patients who underwent sleeve gastrectomy for severe obesity (n = 10 aged 21–48; BMI 48.21 ± 1.14). The mechanical activity from the muscle strips was detected under isometric conditions as the response to increasing concentrations of resveratrol before and after different pharmacological treatments. Resveratrol caused an observable, dose-dependent gastric muscle relaxation. The maximal response caused by the highest concentration of resveratrol was 83.49 ± 2.85% (p < 0.0001) of the control. Preincubation with L-NNA, L-NAME, or ODQ did not prevent the resveratrol-induced relaxation. Apamin, glibenclamide, 4AP or tamoxifen, did not inhibit the relaxing effect of resveratrol, as well. In turn, blocking BKCa by TEA, iberiotoxin, or charybdotoxin resulted in inhibition of resveratrol-induced relaxation (91.08 ± 2.07, p < 0.05; 95.60 ± 1.52, p < 0.01 and 89.58 ± 1.98, p < 0.05, respectively). This study provides the first observation that the relaxant effects of resveratrol in human gastric muscle strips occur directly through BKCa channels and independently of nitric oxide signaling pathways. Furthermore, there is considerable potential for further extensive clinical studies with resveratrol as an effective new drug or health supplement to treat gastrointestinal dyspepsia and other gastric hypermotility disorders.
Transcriptome Analysis Reveals Olfactory System Expression Characteristics of Aquatic Snakes

Animal olfactory systems evolved with changes in habitat to detect odor cues from the environment. The aquatic environment, as a unique habitat, poses a formidable challenge for olfactory perception in animals, since the higher density and viscosity of water. The olfactory system in snakes is highly specialized, thus providing the opportunity to explore the adaptive evolution of such systems to unique habitats. To date, however, few studies have explored the changes in gene expression features in the olfactory systems of aquatic snakes. In this study, we carried out RNA sequencing of 26 olfactory tissue samples (vomeronasal organ and olfactory bulb) from two aquatic and two non-aquatic snake species to explore gene expression changes under the aquatic environment. Weighted gene co-expression network analysis showed significant differences in gene expression profiles between aquatic and non-aquatic habitats. The main olfactory systems of the aquatic and non-aquatic snakes were regulated by different genes. Among these genes, RELN may contribute to exploring gene expression changes under the aquatic environment by regulating the formation of inhibitory neurons in the granular cell layer and increasing the separation of neuronal patterns to correctly identify complex chemical information. The high expression of TRPC2 and V2R family genes in the accessory olfactory systems of aquatic snakes should enhance their ability to bind water-soluble odor molecules, and thus obtain more information in hydrophytic habitats. This work provides an important foundation for exploring the olfactory adaptation of snakes in special habitats.

Diffusive Plasma Transport by the Magnetopause Kelvin-Helmholtz Instability During Southward IMF

At the Earth’s low-latitude magnetopause, the Kelvin-Helmholtz (KH) waves, which are driven by the super-Alfvénic velocity shear across the magnetopause, have been frequently observed during periods of northward interplanetary-magnetic-field (IMF) and believed to contribute to efficiently transporting the solar wind plasmas into the magnetosphere. On the other hand, during southward IMF periods, the signatures of the KH waves are much less frequently observed and how the KH waves contribute to the solar wind transport has not been well explored. Recently, the Magnetospheric Multiscale (MMS) mission successfully detected signatures of the KH waves near the dusk-flank of the magnetopause during southward IMF. In this study, we analyzed a series of two- and three-dimensional fully kinetic simulations modeling this MMS event. The results show that a turbulent evolution of the lower-hybrid drift instability (LHDI) near the low-density (magnetospheric) side of the edge layer of the KH waves rapidly disturbs the structure of the layer and causes an effective transport of plasmas across the layer. The obtained transport rate is comparable to or even larger than that predicted for the northward IMF. These results indicate that the diffusive solar wind transport induced by the KH waves may be active at the flank-to-tail magnetopause during southward IMF.
The Role of Complex Trauma and Attachment Patterns in Intimate Partner Violence

Objective Even if the relationship between adverse childhood experiences and intimate partner violence (IPV) has already been established, there are no sufficient studies examining the relationships between these factors and attachment representations, specifically attachment disorganization. Thus, this study aimed to explore, in a sample of women who experienced IPV (a) the presence of interpersonal adversities during childhood, and (b) attachment representations, with a particular focus on disorganization. Methods Women’s representations of attachment experiences were investigated through the Adult Attachment Interview, while the presence of various forms of interpersonal adversities during childhood was assessed using the Complex Trauma Questionnaire. The results of the IPV group (n = 98) were compared with those of women with no history of IPV (control group, n = 81). Results Women in the IPV group showed higher values of multiple forms of adverse experiences within their caregiving system. They presented significantly higher rates of disorganized states of mind regarding attachment, indicative of a lack of resolution regarding traumatic experiences, and of disorganized working models resulting from complex trauma. Our results highlighted that, more than the presence of traumatic experiences, it is their irresolution – reflected in the disorganized states of mind regarding attachment at the Adult Attachment Interview – to be a significant predictor of IPV. Conclusion These results suggest underline the significance of offering a trauma- and attachment-informed therapy to those who experience IPV. Such results could help both clinicians and researchers in formulating clearer guidelines for IPV interventions.
Impact of Decadal Trends in the Surface Climate of the North Atlantic Subpolar Gyre on the Marine Environment of the Barents Sea

The Barents Sea is a key region in the Earth System and is home to highly productive marine resources. An integrated approach for strategic sustainable management of marine resources in such shelf-sea marine ecosystems requires, among many other aspects, a robust understanding of the impact of climate on local oceanic conditions. Here, using a combined observational and modelling approach, we show that decadal climatic trends associated with the North Atlantic Subpolar Gyre (SPG), within the period 1960–2019, have an impact on oceanic conditions in the Barents Sea. We relate hydrographic conditions in the Barents Sea to the decadal variability of the SPG through its impact on the Atlantic Inflow via the Faroe-Shetland Channel and the Barents Sea Opening. When the SPG warms, an increase in the throughput of subtropical waters across the Greenland-Scotland Ridge is followed by an increase in the volume of Atlantic Water entering the Barents Sea. These changes are reflected in pronounced decadal trends in the sea-ice concentration and primary production in the Barents Sea, which follow the SPG after an advective delay of 4–5 years. This impact of the SPG on sea-ice and primary production provides a dynamical explanation of the recently reported 7-year lagged statistical relationship between SPG and cod (Gadus morhua) biomass in the Barents Sea. Overall, these results highlight a potential for decadal ecosystem predictions in the Barents Sea.
