LEPA: Low-overhead and Efficient Privacy-preserving Authentication Scheme in VANETs
Authors: Moni Shafika Showkat , Manivannan Dakshnamoorthy 
Published: July 2023

Abstract
The dynamic nature of Vehicular
Ad-hoc Networks (VANETs) necessitate suitable authentication schemes to
prevent intruders from compromising the privacy of vehicles. In order to maintain the privacy of vehicles, several schemes using pseudonyms instead of real IDs of vehicles have been proposed in the literature. When vehicles use
pseudonyms instead of their real IDs in their communication,
authenticating the vehicles becomes an issue. Assigning a single
pseudonym to a vehicle does not solve the problem because, based on a
vehicle's trajectory, an intruder can track the
vehicle. So, a vehicle needs to change its pseudonym frequently. So,
to ensure the privacy of the vehicle, each vehicle should be assigned a pool
of pseudonyms, and the vehicle should be able to pick a pseudonym from the pool and
use it and also change its pseudonym periodically. In many of the existing works, for authentication
purposes, a central entity is used to issue certificates corresponding to each
pseudonym assigned to a vehicle and distribute them to the vehicle so it
can present the certificate to authenticate itself. However, this
approach involves significant computation, storage, and distribution
overhead of the revoked certificates of pseudonyms of malicious
vehicles because each vehicle is assigned a large number of pseudonyms.
We address this issue and propose a Low-overhead and Efficient
Privacy-preserving Authentication (LEPA) scheme for VANETs by
leveraging Merkle Hash Tree (MHT) and Cuckoo Filter (CF). We analyze
and verify the robustness of the LEPA scheme against various
attacks. The performance evaluation demonstrates the efficiency of the
LEPA scheme with respect to authentication overhead.

Abstract
The presence of arsenic (As) in irrigation water is a threat to agricultural crops as well as human health. The presence of arsenic and phosphorous in irrigation water influences the behavior of bioaccumulation, biotransfer, and total bioactive compounds in the distinct parts of the onion structure. The present work evaluates the behavior of the bioaccumulation and biotransfer of As in the structures of onion (Alliun cepa) through a composite central design and response surface method. The factors employed include the concentration of arsenic (V) and phosphate (V) in the nutritive solution. Additionally, this study analyzes the behavior of the effect that the induced stress has on the total bioactive compounds (phenols and flavonoids) and antioxidant capacity (ABTS and DPPH) in the onion roots. The results showed that the physiological properties, bioaccumulation factors, As transference, as well as the total bioactive compounds in the onion structure, are affected by the competition of As and phosphates (P(V)) in the irrigation water. For concentrations of As and phosphorous of 450 mg L− 1 and 0.30 mg L− 1 respectively in irrigation water, there are negative effects on the equatorial diameter of the bulb, length, weight of leaf, and weight of bulb. Besides, the transference and bioaccumulation factors range from 2.36 to 22.22 and from 2.15 to 7.81 respectively, suggesting that the plant has a translocated ability of As from root to aerial organs and it is possible to accumulate As. Besides, it is found that under the mean conditions of As and phosphorous in irrigation water, a greater production occurs in total phenolic compounds and antioxidant capacity (ABTS and DPPH) as a response to the stress generated by As.

Published: July 2023

Abstract
Consumption behaviors of tourists and energy consumption of tourism enterprises can cause environmental damage on nature. While environmental pollution in tourism regions as a result of these environmental deteriorations can affect the decisions of tourists, consumption behaviors of tourists in tourism regions can also affect local environmental quality. In this context, the main motivation of the study is to empirically examine the impact of tourism transportation, which is an important component of national income, on environmental pollution in emerging countries. The number of international tourists’ arrivals is used for the tourism, and the ecological footprint is used for the environmental pollution. The number of international tourists is handled in 3 categories: air, water, and land. Analyzes are carried out for 16 emerging countries covering the period 1995-2018. Engle and Granger (1987) co-integration test and the quantile co-integration test proposed by Xiao (2009) which provides the theoretical basis for examining the asymmetric structure in the data set are used as the analysis method. Compared to the conventional testing methodology, the quantile co-integration test provides more evidence for the existence of a co-integration relationship. Therefore, this indicates the efficiency gain of using quantile methods. The increase in international tourist transportation in all countries with a co-integration relationship increases environmental pollution. In addition, the relationship between variables behaves differently in different quantiles. In this context, it has been concluded that there is an asymmetrical adjustment process depending on the sign and size of the shocks. Lastly, it is found that the effects of air, water, and land transportation types on environmental pollution differ on a country basis.

Abstract
Aims
Hypoxic-ischaemic brain damage (HIBD) remains a common sequelae of various nervous system diseases. Human umbilical cord derived mesenchymal stem cells (hUC-MSCs) transplantation was considered to be promising in treating HIBD. However, it remains open the best administration way to transplant hUC-MSCs. In this study, we systematically compared the three administration ways —— the intravenous, the intracerebral and the intranasal administration for the first time to guide the best clinical practice.
Methods
The HIBD rat models were built on postnatal day 7(PN7). And rats were divided into five groups: sham, HIBD, HIBD + IV (intravenous administration), HIBD + IN (intranasal administration) and HIBD + IC (intracerebral administration). The behavioral experiments were used to compare the motor function、learning and memory function improvement of three administration ways, where the motor function of rats on PN10 and PN21 were evaluated by hanging wire and vertical pole test, and the learning and memory function of rats were evaluated by the Morris water maze (MWM) test. Moreover, the pathological tests were used to compare the pathological repair effects of three administration ways: the morphological changes of brain tissue were tested by Haematoxylin and eosin staining; the proliferation of reactive astrocytes were compared by detecting the expression of glial fibrillar acidic protein (GFAP), and the number of neuronal apoptosis in cortex and hippocampus were compared by TUNEL staining.
Results
The motor function of rats in HIBD group was significantly lower than that in sham group on the PN10, both in hanging wire and vertical pole tests (P < 0.0001). This shows the effectiveness of our HIBD model. According to the hanging wire test, the improvement of motor function in HIBD + IN group and HIBD + IC group were more obvious than that HIBD + IV group (P < 0.05), but no significant difference between HIBD + IN group and HIBD + IC group(P > 0.05).

Published: July 2023

Abstract
Generative modeling has seen a rising interest in both classical and quantum machine learning, and it represents a promising candidate to obtain a practical quantum advantage in the near term. In this study, we build over a proposed framework for evaluating the generalization performance of generative models, and we establish the first quantitative comparative race towards practical quantum advantage (PQA) between classical and quantum generative models, namely Quantum Circuit Born Machines (QCBMs), Transformers (TFs), Recurrent Neural Networks (RNNs), Variational Autoencoders (VAEs), and Wasserstein Generative Adversarial Networks (WGANs). After defining four types of PQAs scenarios, we focus on what we refer to as potential PQA, aiming to compare quantum models with the best-known classical algorithms for the task at hand. We let the models race on a well-defined and application-relevant competition setting, where we illustrate and demonstrate our framework on 20 variables (qubits) generative modeling task. Our results suggest that QCBMs are more efficient in the data-limited regime than the other state-of-the-art classical generative models. Such a feature is highly desirable in a wide range of real-world applications where the available data is scarce.
Sea surface temperatures governed the development and longevity of the Great Barrier Reef

Published: July 2023

Abstract
The Great Barrier Reef (GBR) is by far the largest reef system in the modern ocean. Recently, it has been severely affected by coral bleaching due to human-induced warming. To date, however, the influence of temperature on the origin and long-term evolution of the GBR remains enigmatic. The only available sea surface temperature (SST) proxy data set extending beyond the origin of the GBR shows little variability. It has therefore been argued that other environmental factors must have been responsible for the development of the GBR. Here, we present a TEX86H-derived temperature proxy record from ODP Site 820. It demonstrates for the first time that the onset of reef growth on the outer shelf was preceded by a sharp rise in temperature from ~ 26°C before Marine Isotope Stage (MIS) 17 to ~ 28°C starting at MIS 17. After that, reconstructed temperatures remained relatively high (26 to 29°C). This period culminated in the development of a barrier reef system at MIS 13, suggesting that relatively stable SSTs were critical to its evolution. The glacial MIS 12 showed a renewed cooling to temperatures of ~ 25°C. From MIS 11 to the present, the glacial to interglacial temperature fluctuations approximate 3 to 4°C, with MIS 11 and 5 as particularly warm interglacials. The relatively warm temperatures after MIS 18 likely promoted extensive reef growth even during the glacials. These glacial reefs likely contributed to the persistence of the GBR over several glacial-interglacial cycles since the Middle Pleistocene. The evolution of the GBR, therefore, appears to be closely linked to seawater temperature. Our data suggest that sustained periods of optimal temperatures are a prerequisite for the development and maintenance of the GBR.

Published: July 2023

Abstract
Background: Sore throat is the most common complication of tracheal intubation and is an unpleasant complication in patients who undergo general anesthesia with tracheal intubation. Considering the importance of reducing the incidence of postoperative sore throat (POST) and increasing patient satisfaction, in this study we discussed the effectiveness of intranasal dexamethasone in reducing the incidence of POST in patients under general anesthesia.
Methods: This double-blind randomized clinical trial study was carried out on 96 patients over 18 years of age who were candidates for elective eye surgery from July 2019 to March 2020 at Faiz Hospital in Isfahan. The patients were divided randomly into two groups of 48 to receive intranasal Dexamethasone (IND) or intranasal normal saline (INS), administration of drugs was immediately after endotracheal intubation. Demographic data, the presence of sore throat, cough, and hoarseness during the stay in the recovery as well as in the ward (up to 24 hours) were recorded and analyzed by SPSS software version 23.
Results: The results of the current study showed that percentage of sore throat, cough and hoarseness during the stay in the recovery room and 2 hours after entering the ward in the IND group was significantly lower than the INS group (P value<0.001). but at 6, 12, and 24 hours after the stay in Ward, despite the lower frequency of these symptoms in the IND group compared to the INS group, there was no significant difference between the two groups (P value>0.05).
Discussion: This is an innovative clinical trial that evaluate the prophylactic effect of intranasal Dexamethasone in reducing postoperative sore throat. This research shows that intranasal administration of dexamethasone can reduce post-operative sore throat, hoarseness, cough and improve the quality of stay in the recovery room.

Published: July 2023

Abstract
Proinsulin Like Growth Factor (prolGF1) and myostatin (Mstn) regulate muscle regeneration when intravenously delivered. We set out to test if chloroplast bioencapsulated forms of these proteins may serve as a non-invasive means of drug delivery through the digestive system. We created tobacco (Nicotiana tabacum) plants carrying GFP-Fc1, proIGF-I-Fc1, and Mstn-Fc1 fusion genes, in which fusion with the immunoglobulin G Fc domain improved both protein stability and absorption in the small intestine. No transplastomic plants were obtained with the Mstn-Fc1 gene, suggesting that the protein is toxic to plant cells. proIGF-I-Fc1 protein levels were too law to enable in vivo testing. However, GFP-Fc1 accumulated at a high level, enabling evaluation of chloroplast-made Fc fusion proteins for oral delivery. Tobacco leaves were lyophilized for testing in a mouse system. We report that the orally administered GFP-Fc fusion protein (5.45 µg/g GFP-Fc) has been taken up by the intestinal epithelium cells, evidenced by confocal microscopy. GFP-Fc subsequently entered the circulation where it was detected by ELISA. Data reported here confirm that chloroplast expression and oral administration of lyophilized leaves is a potential delivery system of therapeutic proteins fused with Fc, with the advantage that the proteins may be stored at room temperature.
Effect of mindfulness-based interventions on people with prehypertension or hypertension-A systematic review and meta-analysis of randomized controlled trials
Authors: chen qiongshan , du shizheng , liu hui 
Published: July 2023

Abstract
Background: Hypertension and prehypertension has been widely recognized as the main contributor of global mortality. Evidence shows mindfulness-based interventions may reduce blood pressure and improve mental health. However, the effect of mindfulness-based interventions on blood pressure and mental health has not been fully understood.
Methods: Potential studies published before May 24th 2023 were identified by searching Embase, Ovid Emcare, PsycINFO, CINAHL, Web of Science, Cochrane, PubMed, China National Knowledge Infrastructure, Wanfang database, and VIP China Science. Additionally, two grey databases were searched: Mednar, WorldWideScience.org. The risk of bias in the included studies was assessed using the Cochrane Risk of Bias Assessment tool. The random-effects meta-analyses were conducted using Review Man 5.4 software and the key outcomes are presented as mean difference or standard mean difference and the 95% confidential interval.
Results: Searches returned 802 studies in total, of which 12 were included (N = 715). The duration of interventions was 8 weeks in 10 trials and 6 weeks in one trial. Pooled effect sizes indicated reductions in systolic blood pressure (MD = -9.12, 95% CI [-12.18, -6.05], p < 0.001), diastolic blood pressure (MD = -5.66, 95% CI [-8.88, -2.43], p < 0.001), anxiety (SMD = -4.10; 95% CI [-6.49, -1.71], p < 0.001), depression (SMD = -1.70, 95 %CI [-2.95, -0.44], p < 0.001) and perceived stress (SMD = -5.91, 95 %CI [-8.74, -3.09], p < 0.001) at post-intervention. The findings from subgroup analyses are favorable for MBIs regardless of gender and baseline blood pressure with regard to BP reduction, with a more profound effect observed in participants with higher pre-intervention blood pressure.
Conclusions: The results provide evidence for the positive role of mindfulness-based interventions in hypertension management. More large randomized control trials with sufficient statistical power and long-term follow-up are needed.
Registration: The protocol had been registered with Prospero on October 2nd 2021 (registration NO. CRD42021282504).
Highly Directional and Carrier Density-Independent Plasmons in Quasi-One-Dimensional Electron Gas Systems

Published: July 2023

Abstract
Hyperbolic materials (HMs) have garnered significant attention for their distinct electromagnetic response characteristics. Recent advancements in developing meta hyperbolic surfaces through intricate substrate patterning have enabled the realization of highly-directional hyperbolic surface plasmons, which play a crucial role in optoelectronic devices. In this study, we expand the possibility of natural two-dimensional (2D) materials in achieving exceptional electromagnetic scenarios akin to those observed in meta hyperbolic surfaces. Notably, natural hyperbolic 2D materials provide inherent advantages in terms of simplicity, predictability, and lower losses compared to meta-surfaces. By employing first-principles calculations, we unveil the possibility of achieving this mechanism in a realistic 2D material, specifically the RuOCl2 monolayer. Our results demonstrate that the RuOCl2 monolayer sustains carrier-density-independent and broadband low-loss hyperbolic responses across the terahertz to ultraviolet spectral range, owning to the highly-anisotropic electronic band structures characterized by quasi-one-dimensional electron gas (Q1DEG). These findings shed light on the integration of hyperbolicity in natural 2D materials, opening new avenues for the design and development of novel optoelectronic devices and nanoscale imaging systems.

Authors: Makhoul Mikhael , Hourseau Muriel , Nassereddine Hussein , Hamad Walid Abou , Khoueir Nadim 
Published: July 2023

Abstract
Introduction: We report a unique case of a patient with epithelioid hemangioma (EH) of the nasal cavity showing atypical histological features diagnosed using Next-Generation targeted RNA Sequencing that revealed a GATA6-FOXO1 fusion transcript.
The patient’s main concern and important clinical findings: It is a 53-year-old man who was experiencing recurrent episodes of right epistaxis. Nasal endoscopy revealed an exophytic well defined lesion at the head of the right middle turbinate.
The primary diagnosis, interventions, and outcomes: the lesion was resected endoscopically under general anesthesia. Microscopic examination revealed solid sheets of epithelioid tumor cells with some slit-like vascular channels with moderate to severe nuclear atypia. Tumor cells were positive for ERG, CD31, CD34 and GATA6 immunostainings. The proliferation index (Ki-67) was relatively high. A Next-Generation targeted RNA Sequencing shows a GATA6-FOXO1 fusion transcript confirming the diagnosis of epithelioid hemangioma with atypical features. No clinical recurrence was detected on nasal endoscopy during the 12 months follow-up period.
Conclusion:EH of the head and neck region is a diagnostic challenge for both head and neck surgeons and pathologists. The diagnosis is confirmed through histological and immunohistochemical analysis.
Heterogeneity and Geographical Location in Italian Business Networks
Authors: Correani Luca , Ceccarelli Valentina , Morganti Patrizio 
Published: July 2023

Abstract
Business network agreements (BNAs) are an innovative policy tool that allow firms to co- operate on common projects by sharing skills and knowledge. BNAs can be set up either by firms working in the same geographical area or by firms geographically distant among each other. Focusing on Italian networks, we conduct a cross-section empirical analysis to investi- gate the relationship between the average geographical distance among firms in a network and an entropy index measuring the degree of heterogeneity of the activities carried out by network firms. It emerges that the geographical agglomeration of network firms is significantly related to a lower value of the entropy index, though in this case the network tends to be composed by a small number of firms.

A predictive analytics solution matching job seekers' talent and employers' demands based on machine learning
Authors: Rahmani Hamed , Groot Wim , Rahmani Amir Mohammad 
Published: July 2023

Abstract
The Covid-19 Pandemic has led to an increase in online recruitment. Many job seekers and employers post information about their talents, characteristics, and demands on job search websites where a large amount of data is cumulated in an unparsed way. Therefore, job seekers and employers cannot always find their way through this. This research used a sample of data from the most dependable employment and job search website in Iran. By examining the database provided by the website, the study aims to identify, cluster, predict and analyze data related to job seekers and the labour market. This study utilized the CRISP-DM methodology to analyze job seeker and employers' demands data, utilizing clustering algorithms such as self-organizing maps (SOM), Fuzzy C-means (FCM), K-Means, and latent Dirichlet allocation (LDA), with validation using the silhouette criterion. Then Multi-layer Perceptron (MLP), Naive Bayes, Learning Vector Quantization (LVQ), Support Vector Machine (SVM), and Language Model (LM) classification algorithms were used for prediction and classification processes. Results showed that the SOM algorithm had the best clustering with an average silhouette index of 0.92 for job seekers and 0.89 for the labour market. The MLP algorithm with SOM clustering was chosen as the best algorithm for prediction and classification processes with an accuracy of 0.83 which is a relatively high level of accuracy in predictive analytics.
