Cooperative Intelligence of Vehicles for Intelligent Transportation Systems (ITS)
Springer Science + Business Media 2016 Wireless personal communications Vol.87 No.2
<P>The aim of Intelligent Transportation Systems (ITS) is to automate the interactions among vehicles and infrastructure to accomplish high levels of safety measures, comfort, and competence in vehicular communication. To utilize the future trends of increasing traffic safety and efficiency in ITS, integrating vehicles and infrastructures with the cooperative vehicular technique will be the feasible solution. In order to demonstrate the importance of cooperative communication in vehicular networks, a spectral efficient architecture has been proposed for cooperative centralized and distributed spectrum sensing in vehicular networks. We discuss the possibilities of Cognitive Radio in the cooperative vehicular environment. In order to exhibit cooperative vehicular networks, hardware modules are designed for a vehicle to vehicle, vehicle to infrastructure and infrastructure to infrastructure communications. Furthermore, quantitative analysis is made in order to calculate the energy optimization, connectivity failure probability and traffic management in cooperative vehicular networks. In addition, we test the results of the cooperative vehicular network by simulating it in NS2. In this respect, we have considered three different cases, Emergency vehicles, VIP vehicles, and normal vehicles. It is inferred from the results that end-to-end delay for emergency vehicles in the cooperative environment is considerably less as compared to VIP and normal vehicles.</P>

Mass migrations of Slovaks from the north of Hungary to the south (to the Lowland) in the 18th and 19th centuries are part of the migration of serfs as part of the systematic colonization of Empress Maria Theresa after the expulsion of the Turks from this territory. Coexistence with other nations or old settlers, as well as state politics, naturally influenced further development and determined the life of immigrants in national, cultural, economic, social, as well as linguistic terms. The aim of this paper is to present the linguistic situation of the Slovaks in the settlement of Kysáč in today's Serbia based on church documents from their immigration to the end of the First World War. We examined the chronicle of the Kysáč priest František Jesenský from 1773, registers from the years 1787 – 1918, the minutes of the canonical visitation of the Kysáč church choir from 1835, the minutes of the school board of the Kysáč school from the years 1895 – 1915, the minutes of the presbytery conventions 1912 – 1916 and other documents of the church archive of the Slovak Evangelical Church a. c. in Kysáč.

Valproic acid (VPA) is an antiepileptic drug, which is currently used in neurodegenerative diseases. However, a high dose is required to obtain a therapeutic effect. Long-chain polyunsaturated fatty acids (PUFAs), such as omega 3 and omega 6, are efficient complements in treatments for neurological diseases. Previous studies have reported that a dietary supplement containing PUFAs together with the administration of antiepileptic drugs significantly reduces the frequency of seizures. Based on this, the main goal of this work was to obtain a complex based on VPA encapsulation in an oil/water (o/w) nutraceutical emulsion (NE) enriched with PUFAs for oral administration. Besides, encapsulation of VPA might reduce its dose and increase its therapeutic effect. In order to study its effect, we used a zebrafish larvae model of induced epileptiform behavior with the proconvulsant drug pentylenetetrazol (PTZ). Results have shown that when 100 μM VPA and fatty acids were combined in the NE (NE-VPA), the epileptiform behavior of PTZ-treated zebrafish larvae decreased significantly. Additionally, morphological changes, hepatotoxicity, lethality and heart rate were studied. Despite the fact that a high dose of VPA exerted a cardiotoxic effect, this was no longer detected after addition of this drug in the NE. This treatment exerted a significant antiepileptic effect and did not result in highly toxic or lethal effects. In order to develop an improved pharmaceutical treatment, and considering that all the components used are FDA approved for consumption, the NE-VPA selected might be easily incorporated into clinical trials.

Environmental agents, including viral and bacterial infectious agents, are involved in the alteration of physicochemical and biological parameters in the nasal epithelium. Hyaluronan (HA) has an important role in the regulation of tissue healing properties. High molecular weight HA (HMW-HA) shows greater anti-inflammatory responses than medium molecular weight HA (MMW-HA) and low molecular weight HA (LMW-HA). We investigated the effect of HMW-HA, MMW-HA and LMW-HA on the regulation of physicochemical and biological parameters in an “in vitro” model that might mimic viral infections of the nasal epithelium. Human nasal epithelial cell line RPMI2650 was stimulated with double-stranded RNA (dsRNA) Poly(I:C) for 5 days in air-liquid-interface (ALI) culture (3D model of airway tissue). dsRNA Poly(I:C) treatment significantly decreased transepithelial electrical resistance (TEER) in the stratified nasal epithelium of RPMI2650 and increased pH values, rheological parameters (elastic G’ and viscous G’’), and Muc5AC and Muc5B production in the apical wash of ALI culture of RPMI2650 in comparison to untreated cells. RPMI2650 treated with dsRNA Poly(I:C) in the presence of HMW-HA showed lower pH values, Muc5AC and Muc5B production, and rheological parameters, as well as increased TEER values in ALI culture, compared to cells treated with Poly(I:C) alone or pretreated with LMW-HA and MMW-HA. Our 3D “in vitro” model of epithelium suggests that HMW-HA might be a coadjuvant in the pharmacological treatment of viral infections, allowing for the control of some physicochemical and biological properties affecting the epithelial barrier of the nose during infection.
Output-Feedback Adaptive Control for the Global Regulation of Robot Manipulators with Bounded Inputs
Daniela J. López-Araujo,Arturo Zavala-Río,Víctor Santibáñez,Fernando Reyes 제어·로봇·시스템학회 2013 International Journal of Control, Automation, and Vol.11 No.1
In this paper, an output-feedback adaptive scheme for the global position stabilization of robot manipulators with bounded inputs is proposed. Compared to the previous output-feedback adap-tive approaches developed in a bounded-input context, the proposed free-of-velocity feedback control-ler guarantees the adaptive regulation objective: globally, avoiding discontinuities throughout the scheme, preventing the inputs to reach their natural saturation bounds, and imposing no saturation- avoidance restriction on the control gains. Moreover, the developed scheme is not restricted to the use of a specific saturation function to achieve the required boundedness, but may involve any one within a set of smooth and non-smooth (Lipschitz-continuous) bounded passive functions that include the hy-perbolic tangent and the conventional saturation as particular cases. Experimental results corroborate the efficiency of the proposed scheme.

Diversity of bacterial endophytes associated with grapevine leaf tissues was analyzed by cultivation and cultivation-independent methods. In order to identify bacterial endophytes directly from metagenome, a protocol for bacteria enrichment and DNA extraction was optimized. Sequence analysis of 16S rRNA gene libraries underscored five diverse Operational Taxonomic Units (OTUs), showing best sequence matches with γ-Proteobacteria, family Enterobacteriaceae, with a dominance of the genus Pantoea. Bacteria isolation through cultivation revealed the presence of six OTUs, showing best sequence matches with Actinobacteria, genus Curtobacterium, and with Firmicutes genera Bacillus and Enterococcus. Length Heterogeneity-PCR (LH-PCR) electrophoretic peaks from single bacterial clones were used to setup a database representing the bacterial endophytes identified in association with grapevine tissues. Analysis of healthy and phytoplasma- infected grapevine plants showed that LH-PCR could be a useful complementary tool for examining the diversity of bacterial endophytes especially for diversity survey on a large number of samples.

Although the antioxidant capacity of carotenoids and their role in regulating membrane fluidity have been well studied, their ability to confer resistance to hypoosmotic shock is poorly understood. In this work, we analyzed the effect of a mixture of carotenoid pigments obtained from an Antarctic microorganism belonging to the genus Pedobacter on liposomal resistance to hypoosmotic conditions. Intercalation of pigments into liposomal structures resulted in an improvement of membrane resistance by decreasing the percentage of calcein released in comparison to that by liposomes without pigments. Due to these properties, such pigments could be useful for biotechnological applications.

This work aimed to develop an edible coating based on Mexican lime ( Citrus aurantifolia Swingle) pectic extract and essentialoil on Haden mango ( Mangifera indica L.) to extend its shelf life. Mango cubes were coated by immersion in a lime pecticextract (1% pectin w/v), lime essential oil (0.05% v/v), and glycerol (0.7% v/v) solution for 2, 5, and 10 min. Subsequently,coated and uncoated (control) test samples were stored for 21 days, and physical–chemical and microbiological analyseswere performed every 3 days. The results showed no signifi cant diff erences for total soluble solids, pH, and fi rmness. On thesixth day, bacterial growth was signifi cantly lower in coated mangos than in the control (log 6.08 ± 0.49 and 7.63 ± 0.20 UFCg −1 , respectively). The application of the edible coating extended the shelf life of minimally processed mangos by 3 days,delaying physical and chemical changes as well as bacterial growth.

The objective of this investigation is to evaluate a series of polymer electrolyte membrane materials based on sulfonated ladder pyridine polymers and SiO2 nanoparticles that enhance water retention and favor high temperature (> 120°C) applications. Nanoparticles are used to improve water uptake at levels of 20–38% to increase the level of sulfonation. A study of relevant characteristics of these polymers will provide an alternative to existing polymers, thus offering simple processing steps, as well as nonexotic polymers and higher performances.
