Optimal Cache Deployment for Video-On-Demand in Optical Metro Edge Nodes under Limited Storage Capacity

Network operators must continuously explore new network architectures to satisfy increasing traffic demand due to bandwidth-hungry services, such as video-on-demand (VoD). A promising solution which enables offloading traffic consists of terminating VoD requests locally through deploying caches at the network edge. However, deciding the number of caches to deploy, their locations in the network and their dimensions in terms of storage capacity is not trivial and must be jointly optimized, to reduce costs and utilize network resources efficiently. In this paper, we aim to find the optimal deployment of caches in a hierarchical metro network, which minimizes the overall network resource occupation for VoD services, in terms of number of caches deployed across the various network levels, their locations and their dimensions (i.e., storage capacity), under limited storage capacity. We first propose an analytical model which serves as a tool to find the optimal deployment as a function of various parameters, such as popularity distribution and location of metro cache. Then, we present a discrete-event simulator for dynamic VoD provisioning to verify the correctness of the analytical model and to measure the performance of different cache deployment strategies in terms of overall network resource occupation. We prove that, to minimize resource occupation given a fixed budget in terms of storage capacity, storage capacity must be distributed among caches at different layers of the metro network. Moreover, we provide guidelines for the optimal cache deployment strategy when the available storage capacity is limited. We further show how the optimal deployment of caches across the various metro network levels varies depending on the popularity distribution, the metro network topology and the amount of storage capacity available (i.e., the budget invested in terms of storage capacity).

Saduriella, a new genus of Isopoda Valvifera from northwestern Spain

During the summers of 1962 and 1963 the Geologisch en Mineralogisch Instituut of Leiden University and the Rijksmuseum van Natuurlijke Historie at Leiden carried out a joint exploration of the geology, oceanography and biology of Ria de Arosa, a fiord-like bay in northwestern Spain, north of Vigo. These investigations were not confined to the Ria proper, but also included the affluent rivers like the Rio Ulla and Rio Umia. These explorations will be continued in 1964. In July 1963 a specimen of a peculiar isopod was found by the oceanographic party when exploring the Rio Ulla, a river emptying in the northeastern corner of the Ria de Arosa. This find caused the biologists to give more attention to the locality where the animal was caught and many more specimens were obtained there during a trip specially organized for the purpose. A study of the collected material revealed that the isopods are Valvifera belonging to the subfamily Mesidoteinae of the family Idoteidae. However, they could not be fitted into any of the known genera of this subfamily and consequently are described here as constituting a new genus and species. The facts that (1) the species is not rare in the type locality, (2) the specimens are of good size, measuring up to 15 mm, and (3) they inhabit a habitat which is neither unusual nor difficult to explore, make it difficult to understand why the present form has not been discovered before. As the type locality is not very close to any big harbour, it seems unlikely that the species has been accidentally introduced there from somewhere else. A thorough exploration of other brackish waters along the European southwest coast may show that the species also occurs elsewhere in that area.
Regional output feedback stabilization of semilinear time‐fractional diffusion systems in a parallelepipedon with control constraints

This article is concerned with the regional output feedback stabilization problems for semilinear time‐fractional diffusion systems in a 1≤n−dimensional parallelepipedon with control inequality constraints. For this, the spectrum decomposition method is used to derive a finite‐dimensional fractional ordinary differential equation (ODE) system that captures the dominant dynamics of the considered system. With this ODE system, we propose a finite‐dimensional fractional compensator to guarantee that the constrained closed‐loop semilinear systems are Mittag‐Leffler stable in some subregions of their evolution domains. An example is finally included to illustrate our results.
Exploration of Endophytes from Alfalfa (Medicago sativa L.) as Biocontrol Agents

Endophytes are increasingly investigated as biocontrol agents for agricultural production. The identification of new endophytes with high effectiveness against plant disease is very important. A total of 362 strains of endophytes, including fungi, bacteria, and actinomycete, were isolated from alfalfa (Medicago sativa L.) collected in Hebei, Inner Mongolia and Ningxia provinces of China. The three strains of endophytic bacteria (NA NX51R-5, NA NX90R-8, and NA NM1S-1) with strong biocontrol capability with >50% effectiveness were screened against the common alfalfa root rot pathogen Fusarium oxysporum F. sp. medicaginis in alfalfa seedling germination experiments on MS medium and pot experiments. Using phylogenetic analysis, the isolates of NA NM1S-1 and NA NX51R-5 were identified as Bacillus spp. by 16S rDNA, while NA NX90R-8 was found to be Pseudomonas sp.
The Relationship between psychosocial health status and risk of depression among pregnant women in Turkey

Background & aim: Pregnancy involves physiological, psychological, and social changes, in which women are expected to adapt to the biopsychosocial changes. Failure to make such an adaptation would be accompanied by an increased risk of prenatal depression in pregnant women. This study was conducted to determine the relationship between psychosocial health status and the risk of depression in pregnant women. Methods: This descriptive-analytic study was carried out on 792 pregnant women (i.e., 73, 369, and 350 cases in the first, second, and third trimesters, respectively) referring to the Outpatient Clinic of the Meram Medical Faculty Hospital, Necmettin Erbakan University, Turkey, from 22 March to 30 June 2016. The pregnant women who attended the outpatient clinic and met the inclusion criteria were selected using haphazard sampling, as a non-probability sampling method. The data were collected through a researcher-made questionnaire, the Pregnancy Psychosocial Health Assessment Scale (PPHAS), and the Edinburgh Postnatal Depression Scale (EPDS). Data analysis was performed in SPSS software (version 22) using descriptive statistics, Mann-Whitney U test, and Kruskal Wallis test. Results: The pregnant women had the depression risk of 28.2% and mean depression score of 9.41±4.8. The total mean score of PPHAS was obtained as 4.05±0.45. The risk of depression showed a statistically negative relationship with the total and sub-dimension mean scores of PPHAS, as well as the mean EPDS score (P˂0.001). Conclusion: Pregnant women with lower psychosocial health status were more likely to have the risk of depression. In other words, the risk of depression in pregnant women was influenced by factors that determine their psychosocial health.

Methyl 4-Hydroxy-2,2-Dioxo-1H-2λ6,1-Benzothiazine-3-Carboxylate and Its Analogs Modified in the Benzene Moiety of the Molecule as New Analgesics

In order to identify new regularities of the “structure–analgesic activity” relationship in the series of 2,1-benzothiazine derivatives, the synthesis of methyl 4-hydroxy-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxylate and a group of its analogs substituted in the benzene moiety of the molecule, as well as their mono-and diammonium salts, was performed with tris(hydroxymethyl)aminomethane. The algorithm was proposed; it allows for uniquely solving the question of the nature of the substituent and its true position in the benzothiazine core based on the complex use of NMR (1H and 13C) and mass spectrometry data. Using single-crystal X-ray diffraction analysis it was proven that salt formation first passes through the cyclic sulfamide group and only then through the 4-hydroxyl group, and is always accompanied by a significant conformational rearrangement of the molecule. Based on the results of pharmacological tests it was found that modification of the benzene moiety of the molecule can be used as a method for enhancing the analgesic properties of the class of compounds studied. The presence of a substitute in position 7 is particularly effective, regardless of its nature. A comparative analysis of the analgesic activity of the initial esters and their mono- and diammonium salts convincingly showed that the common belief about a direct relationship between the solubility of a substance and the level of its biological effect is not always true. As it turned out, increasing the solubility in water can lead to a variety of consequences: From a significant increase in analgesia to its complete elimination. It was suggested that the analgesic activity of the compounds studied is determined not by solubility, but by the molecular conformations formed during their obtainment.
Achieving High UAV Uplink Throughput by Using Beamforming on Board

High-throughput unmanned aerial vehicle (UAV) communication may unleash the true potential of novel applications for aerial vehicles but also represents a threat for cellular networks due to the high levels of generated interference. In this article, we investigate how a beamforming system installed on board a UAV can be efficiently used to ensure high-throughput uplink UAV communications with minimum impact on the services provided to users on the ground. We study two potential benefits of beamforming, namely, spatial filtering of interference and load balancing, considering different beam switching methodologies. Our analysis is based on system-level simulations followed by a series of measurement campaigns in live Long-Term Evolution (LTE) networks. Our results show that using UAV-side beamforming has a great potential to increase uplink throughput of a UAV while mitigating interference. When beamforming is used, even up to twice as many UAVs may be served within a network compared with UAVs using omni-directional antennas, assuming a constant uplink throughput target. However, to fully exploit the potential of beamforming, a standardized solution ensuring alignment between network operators and UAV manufacturers is required.
Design by neural network of concentric multilayered cylindrical metamaterials

Artificial neural networks (NNs) that have deeply learned the optical responses from metamaterials can predict the optical spectra from a given metamaterial without solving Maxwell’s equations. Prediction is extremely fast because of the low computational complexity. We report here two inverse designs of concentric multilayered cylinder metamaterials, using trained NN models, and discuss the accuracy of the prediction. We also predict a cloaking condition for invisibility having performance better than that derived by transformation optics, as a further application of NNs to metamaterial design.
Wigeongrass (Ruppia maritima): A Literature Review.

Abstract : Wigeongrass (Ruppia maritima L.) is a submersed macrophyte of nearly cosmopolitan distribution and worldwide importance as a waterfowl food. Unfortunately, the plant no longer inhabits vast areas disturbed by human activities. Taxonomic status of the plant is uncertain, especially in North America. In mild climates, in habitats subject to environmental extremes, the plant behaves as an annual (vegetation perishes), or as a perennial in deeper, more stable habitats (some vegetative parts grow year round). Drupelets (seeds) provide a mechanism for wigeongrass to survive periods of drought and excessive water salinity. These sexual propagules can be washed ashore or carried by birds or fish for long distances. Wigeongrass mostly occurs in temporarily to permanently flooded mesohaline-hyperhaline estuarine wetlands, but it also occurs inland in fresh to hypersaline palustrine and lacustrine wetlands. Most populations inhabit warm, relatively unpolluted, and well lit waters <2.0 m deep where fetches and wave action are not great. The species is probably best adapted to stable water levels but can tolerate significant water level fluctuations, including periodic exposure in tidal areas. Robust growth occurs in areas of slow current. Wigeongrass is alone among the submersed North American angiosperms in tolerance to high salinity, but it is likely at a competitive disadvantage among specialist taxa in soft or acidic waters. The species grows in nearly all common bottom substrates, but growth is favored by aerobic and low H2S conditions. Turbidity frequently limits wigeongrass growth in waters overlying easily suspendible bottom substrates. Wigeongrass often occurs in monotypic stands, yet grows with many other submersed and emergent macrophytes.

Optimizing Nitrogen Application for Growth and Productivity of Pomegranates

Quantification of actual plant consumption of nitrogen (N) is necessary to optimize fertilization efficiency and minimize contamination of earth resources. We examined the performance of fruit-bearing pomegranate trees grown in soilless media and exposed to eight N-fertigation treatments, from 5 to 200 mg N L−1. Reproductive and vegetative indices were found to be optimal when 20 to 70 mg N L−1 was supplied. Nitrogen application levels over 70 mg L−1 reduced pomegranate development and reproduction. N uptake in low-level treatments was almost 100% and decreased gradually, down to 13% in 200 mg N L−1 treatment. N usage efficiency was maximized under 20 mg N L−1, in which case 80% to 90% of added N was taken up by the trees. At high N application, its efficiency was reduced with less than 50% utilized by the trees. Leaf N increased to a plateau as a function of increasing irrigation solution N, maximizing at ~15 to 20 mg N g−1. Therefore, analysis of diagnostic leaves is not a valid method to identify excessive detrimental N. The results should be valuable in the development of efficient, sustainable, environmentally responsible protocols for N fertilization in commercial pomegranate orchards, following adaptation and validation to real soil field conditions.
Imigração e resistência

This article aims to analyse the representation of female characters in the context of German language immigration literature. With focus on resistance, this article discusses the intersection of gender and immigration in the short story “Schatten und Schritte” written by Aysel Ozakin and the novel All Russians Love Birch Trees by Olga Grjasnowa. The first text, published in 1985, presents a voice of the first wave of the history of migratory flows to Germany, the second one, published in 2012, develops a discussion about female perceptions and resistance practices after the turn of the millennium. Resistance is understood in this context as a process of recognizing, naming and repressing acts which produce inequalities. The first text connects resistance to a feeling of guilt, the second focusses, above all, on the autonomy obtained through acts of resistance.
Effects of Replacing In-feed Antibiotics with Synergistic Organic Acids on Growth Performance, Health, Carcass, and Immune and Oxidative Statuses of Broiler Chickens Under Clostridium perfringens Type A Challenge

SUMMARY. This study was conducted to investigate the effects of replacing in-feed antibiotics with synergistic organic acids on growth performance, health, carcass, and immune and oxidative statuses of broiler chickens under Clostridium perfringens (CP) type A challenge. Two organic acid products were tested: organic acid 1 (OA1), consisting of butyrate, medium-chain fatty acids, organic acids, and phenolics; and organic acid 2 (OA2), consisting of buffered short-chain fatty acids. Six hundred 1-day-old male Arbor Acres broiler chicks were randomly assigned to one of five treatments: Control 1, basal diet, nonchallenged birds; Control 2, basal diet, with CP challenge; antimicrobial growth promoters (AGP), basal diet supplemented with Aureomycin (chlortetracycline), with CP challenge; OA1, basal diet supplemented with OA1, with CP challenge; and OA1OA2, basal diet supplemented with OA1 and OA2, with CP challenge. Each treatment had eight replicate pens of 15 birds. The experiments lasted for 29 days. The disease challenge was performed on days 15–17, with an oral gavage of 0.5 mL of CP culture (2.0 × 108 colony-forming units [CFU]/mL) for each bird. Body weights (BWs), intestinal lesion scores, immune organ indices, and serum malondialdehyde (MDA) concentrations were measured on days 19, 22, and 29, respectively, in three birds per pen. Carcass characteristics were determined on day 29. No treatment-related differences in mortality were noted before (P = 0.28) or after (P = 0.64) challenge or over the whole study period (days 0–28; P = 0.66). On day 19, the BW of Control 2 was lower than other treatments (P < 0.0001). On day 22, AGP, OA1, and OA1OA2 had higher BW than Control 2 (P = 0.001). The breast muscle yield of OA1 and OA1OA2 was higher than AGP (P < 0.05). The abdominal fat yield of OA1OA2 was lower than AGP and Control 2 (P < 0.05). On day 22, the birds fed OA1OA2 showed lower intestinal lesion scores than OA1 (P < 0.05). No treatment-related differences in immune organ (spleen, thymus, and bursa) indices were noted (P > 0.05). On day 29, the MDA concentration of OA1 and OA1OA2 was lower than those of Control 1 and AGP (P < 0.05). In conclusion, the addition of organic acids may protect broiler chickens from severe intestinal lesions and oxidative stress and may help reduce abdominal fat mass deposition. There is potential for organic acid–based products as alternatives for AGP in preventing necrotic enteritis in broilers.
