Outage Performance of Power Beacon-Aided Multi-Hop Cooperative Cognitive Radio Protocol Under Constraint of Interference and Hardware Noises

In this paper, we evaluate end-to-end outage probability of a multi-hop decode-and-forward relaying protocol in underlay cognitive radio network. In the proposed protocol, named COOP, secondary nodes including source and relays have to harvest radio-frequency energy from multiple secondary power beacons, and adjust their transmit power, follows a pre-determined interference threshold given by multiple primary users. To enhance the outage performance for the secondary network under an joint constraint of the interference threshold, Rayleigh fading channel and hardware noises caused by imperfect transceiver hardware, the secondary relays on the source-destination path cooperate to forward the source data to the destination. Particularly, they attempt to receive the source data from their previous nodes, and forward it to the secondary destination if requested. Moreover, whenever the destination cannot receive the source data successfully, a successful relay that has the shortest distance to the destination is selected for retransmission. Due to usage of the cooperative transmission, the proposed COOP protocol obtains better performance, as compared with the corresponding multi-hop relaying one (denoted DIRECT) which only uses direct transmission at each hop. We evaluate the outage performance of COOP and DIRECT via both simulation and theory. The obtained results present a significant performance enhancement, as comparing COOP with DIRECT.
Melatonin attenuates light-at-night effects on systolic blood pressure and body temperature but does not affect diastolic blood pressure and heart rate circadian rhythms

ABSTRACT Aim of the present study is to assess whether 1.5mg of exogenous melatonin provided under modified CR in constant light (~400 lx) is capable to mimic effects of dark phase. Forty-six young adults (YA), 17–24 years old of both genders were studied under amodified CR protocol for 26 h. Initially, participants were investigated under constant light (CR-LL) and 2 weeks later under the same conditions though 1.5mg melatonin (Melaxen) was given orally at 22:30. Systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR) and body temperature (BT) were measured every 2 h. To verify the effect of constant light, formerly published results obtained under light-dark conditions (CR-LD) were reanalyzed. Administration of 1.5 mg of exogenous melatonin modified the 24 h patterns of BT and SBP within short 3.5 h time window but did not influence DBP and HR. A short-term reduction of SBP and BT for 1.5–3.5 hours was observed. The values in the CR-LL+M group were significantly lower than in CR-LL at 2:00 h. Hence, exogenous melatonin did mimic the scotophase. Though this effect was gender-specific and found only in female YA. Results of this study prompt further research to qualify and quantify dosage-, duration- and time-dependent differences of melatonin effects, to discern between short-term (acute) and long-term (chronic) melatonin administration, and to clarify its underlying mechanisms.

Design innovation of fish cooling system using liquefied petroleum gas fuel

Fresh fish is known as one of the highly perishable foods. Losses in the primary fish harbor and seafood production are significant, with discarding rates between 9-15%, and more losses occur during fresh fish distribution. This research was an effort to provide better fresh fish distribution equipment using a refrigerator cooling system with Liquefied Petroleum Gas (LPG) fuel generator as a power source. LPG was chosen because it is more economical and profitable than gasoline. Based on fuel consumption, LPC was40.71% lower than premium gasoline, 62.63% lower than pertamax gasoline, and 64.85% lower than pertamax plus gasoline. The calculation of refrigeration heat load was carried out by applying heat transfer theory. Since the refrigeration heat load obtained was 310 Watt, then the type and capacity of the generator was easily determined.
Volatiles profiling and antioxidant activity of Moroccan Artemisia ifranensis J. Didier and Anacyclus pyrethrum Link essential oils

Moroccan indigenous and spontaneous medicinal plants have been widely used to treatment of a number of diseases. Volatile compounds mixtures isolated from leaves and roots respectively of Artemisia ifranensis and Anacyclus pyrethrum species, by hydrodistillation, were analyzed by (GC/FID) and (GC/MS). Oils chemical profile of plant species showed the presence of major compounds among the identified constituents, this is respectively β-thujone (41.12 %) and spathulenol (16.9 %). Essential oils studied are screened also for their, in vitro, antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The noted results reported that Artemisia ifranensis essential oil exhibited promising antioxidant profile, and revealed an antioxidant property more important (IC50 = 5.9 mg/ml) than that of ascorbic acid used in food and pharmaceutical industries (IC50 = 8.09 mg/ml). This essence can be considered as a valuable source of natural antioxidants. Hence, oil of A. pyrethrum has a low efficient antioxidant potency (IC50 values 30.05 mg/ml), compared to the tested samples. The results supported the traditional usage and also possible use of plants volatile oils in combination with other preservatives to protect food materials against a variety of oxidative systems, in pharmaceutical and cosmetic industries.
Campo étnico, polos de capital y estrategias. El caso de los jóvenes marroquíes en Bizkaia.

In this article we analyze the incorporation strategies of the Moroccan youngsters in the province of Bizkaia, using a theoretical approach based in Pierre Bourdieu’s fields theory. Through the analysis of an array of cualitative interviews, we identify the ethnic cultural capital poles that have influence in Moroccan youngsters, and we define two ideal types of incorporation strategies: The ethnic retreat and the assimilation. The results show that the assimilation strategy offers a less access to material resources.

Proposing an Elliptic Curve Cryptosystem with The Symmetric Key for Vietnamese Text Encryption and Decryption

The article describes the basic idea of Elliptic curve cryptography (ECC). Elliptic curve arithmetic can be used to develop Elliptic curve coding schemes, including key exchange, encryption, and digital signature. The main attraction of Elliptic curve cryptography compared to RSA is that it provides equivalent security for a smaller key size, which reduces processing costs. To encode the Vietnamese text, we are based on the sound of Vietnamese characters to make a table of these characters’ order. We are also based on the algorithm to create the data sequence as the basis of building an encryption algorithm by using Elliptic curves on finite fields with symmetric keys to encrypt this Vietnamese text.

Inference of genomic spatial organization from a whole genome bisulfite sequencing sample

Common approaches to characterize the structure of the DNA in the nucleus, such as the different Chromosome Conformation Capture methods, have not currently been widely applied to different tissue types due to several practical difficulties including the requirement for intact cells to start the sample preparation. In contrast, techniques based on sodium bisulfite conversion of DNA to assay DNA methylation, have been widely applied to many different tissue types in a variety of organisms. Recent work has shown the possibility of inferring some aspects of the three dimensional DNA structure from DNA methylation data, raising the possibility of three dimensional DNA structure prediction using the large collection of already generated DNA methylation datasets. We propose a simple method to predict the values of the first eigenvector of the Hi-C matrix of a sample (and hence the positions of the A and B compartments) using only the GC content of the sequence and a single whole genome bisulfite sequencing (WGBS) experiment which yields information on the methylation levels and their variability along the genome. We train and test our model on 10 samples for which we have data from both bisulfite sequencing and chromosome conformation experiments and our most relevant finding is that the variability of DNA methylation along the sequence is often a better predictor than methylation itself. We then run a prediction on 206 DNA methylation profiles produced by the Blueprint project and use ChIP-Seq and RNA-Seq data to confirm that the forecasted eigenvector delineates correctly the physical chromatin compartments observed with the Hi-C experiment.
Ecophysiological aspects of Tachigali vulgaris seedlings using different sources and doses of nitrogen

This study aimed to evaluate the effects of sources and increasing doses of nitrogen on growth and gas exchange in plants of Tachigali vulgaris. The experiment was conducted in a greenhouse in the period from April to July 2015. The experimental design was randomized blocks in a factorial scheme (4 x 5), corresponding to 4 sources and 5 doses with four replications. The seedlings were grown in pots containing 3 dm 3 of soil. Nitrogen sources such as urea [(NH2)2CO], ammonium nitrate (NH4NO3), ammonium sulfate [(NH4) 2SO4] and calcium nitrate [Ca (NO3)2] were tested in five doses of 0, 75, 150, 225 and 300 mg/dm3. They were applied as a solution in four portions, 25, 50, 75 and 100 days after transplanting. The lower growth of cultivated plants may be associated with N-NH4 + and lower photosynthetic activity, especially due to negative action of this ion on stomatal conductance. The occurrence of this ion resulted in lower growth and biomass production. Based on the results, for the production of tachibranco seedlings (Tachigali vulgaris) dose of 150 mg dm -3 of N applied in installments, 25, 50, 75 and 100 days, by applying ammonium nitrate is recommended.

The qualitative approach will be used in this research, and the method to be employed is the multiple case study, where more than one object of study will be considered, with an exploratory and descriptive character. The objectives were achieved, the main social, environmental and economic characteristics were recorded.
Shifting the Paradigm on Cannabis Safety

The global movement toward legalization of cannabis is resulting in an ever-increasing public perception that cannabis is safe. Cannabis is not the first drug to be available for nonmedical use, nor is it the first to have such an unfounded safety profile. The safety of long-term exposure to phytocannabinoids is misunderstood by, and under reported to, the general public. There is evidence to suggest that long-term use of recreational cannabis may be associated with an increased risk of undesirable side effects. This evidence warrants both appropriate caution from the general public and investment in further research by government and industry sectors that are profiting from the sale of these potent psychoactive agents. There is no doubt that these compounds have medical potential. However, in addition to the medical potential, we must also remain aware of the adverse health effects that are becoming synonymous with recreational cannabis use. This perspective highlights the privileged role that cannabis has as a perceived “safe drug” in society and summarizes some concerning side effects that are becoming associated with regular nonprescribed cannabis use.
The effect of dietary supplementation on Salmonella typhimurium colonization in the turkey crop

The pre-harvest use of supplements to reduce the incidence of crop contamination in turkeys was investigated. As opposed to other studies that used a carbohydrate or lactic acid bacteria supplementation prior to slaughter in extended feed withdrawal times, this study challenged poults before their natural nocturnal fast to determine the effects of supplementation on Salmonella challenge during grow-out. Three-week-old turkey poults, on a 2.5% lactose and lactobacillus acidophilus (lxl09 organisms/liter) drinking water supplement from day of hatch, were orally challenged with l.7x108 naldixic-acid resistant Salmonella enterica serovar Typhimurium strain 4232. Crop ingesta and tissue were collected at timepoints 0.5, 4, 8, and 24 hours post challenge. Crop ingesta and crop wall tissue were separately weighed and pulverized in a stomacher. Ten-fold serial dilutions were made in peptone water and plated on XL T 4 media. An immunohistochemical staining procedure was used to explore the effects of supplementation on invasion, clearance, and multiplication of Salmonella typhimurium in vivo. Results from this study indicate that lactose and L. acidophilus supplementation did not reduce S. typhimurium colonization after challenge.

Electrophysiological measures of sleep pressure during wakefulness in the course of isolation at the Concordia Antarctica station and physical activity as a countermeasure

Concordia station in Antarctica is one of the most remote human outpost on Earth. Because of its geographical location, a winterover at Concordia shares a lot of stressors with a space mission. Following a recent study on the markers of sleep pressure during wakefulness on board of the International Space Station, we were investigating if long term isolation in a space analogue station shows similar effects on sleep pressure. Unlike in space, markers of sleep pressure did not increase during isolation’s constant darkness period in Antarctica. When measures of sleep pressure were high in the evening, psychological strain was increased, emphasising the importance of keeping sleep pressure under physiological levels during the mission. As a first indication for a countermeasure, we showed that one hour of bicycle exercise during lunch time could decrease sleep pressure. All these observations need to be further studied in a more controlled environment.
