Network Stability Based on the Amount of Available Bandwidth in a Software Defined Networking

The modern day Network operators, several network users and some sensitive applications running in the network environment have recognized the impact of the network available bandwidth (ABW) estimation as significant due to its importance. The significance is very unique most especially to video streaming applications, peer-to-peer video conference and the selection of some improved dedicated services from network servers. Moreover, determining the amount of available bandwidth within the network can help in designing a guaranteed network stability mechanism within a typical scalable network. Several algorithms and tools were proposed in the literature to estimate the amount of bandwidth available within a network, but the application of the estimation has been unused to address optimal network performance in relation to network stability. Therefore, this paper utilized the improved calibrated pathload algorithm that is enhanced by the correlation coefficient technique to improve the network stability. This ABW information is exploited to direct critical flows over a suitable path through the installation of OpenFlow rules on the switches. These rules were installed likewise as modules into the controller. The initial performance evaluation showed that our proposed approach significantly improved both the bandwidth utilization and the stability of the network in comparison to the ticket probing approach.
Small-Signal Stability Analysis of Wind Power Integrated System with Different PSS Models

With further research on integrated energy systems and energy interconnection, the small-signal stability of wind power integrated system is becoming increasingly dramatically. This paper adopts a coordinated approach using eigen-analysis and time simulation for studying the impact of PSS as well as determining the PSS location and optimizing parameters through the residue index and probabilistic sensitivity indices (PSIs). Two types of PSS are implemented on a 2-area 4-unit and 8-unit 24-bus power systems with wind power to get comparative analysis on different PSSs improvement of system damping characteristics. The results obtained by case studies show that the PSS second-order model has stronger robustness to improve the system damping, and the selection of PSS types with coordinated optimization can affect the effectiveness of wind power integrated system damping performance improvement.
Human‐Induced Pluripotent Stem Cell Culture Methods Under cGMP Conditions

Abstract The discovery of induced pluripotent stem cells (iPSCs) revolutionized the approach to cell therapy in regenerative medicine. Reprogramming of somatic cells into an embryonic‐like pluripotent state provides an invaluable resource of patient‐specific cells of any lineage. Implementation of procedures and protocols adapted to current good manufacturing practice (cGMP) requirements is critical to ensure robust and consistent high‐quality iPSC manufacturing. The technology developed at Allele Biotechnology for iPSC generation under cGMP conditions is a powerful platform for derivation of pluripotent stem cells through a footprint‐free, feeder‐free, and xeno‐free reprogramming method. The cGMP process established by Allele Biotechnology entails fully cGMP compliant iPSC lines where the entire manufacturing process, from tissue collection, cell reprogramming, cell expansion, cell banking and quality control testing are adopted. Previously, we described in this series of publications how to create iPSCs using mRNA only, and how to do so under cGMP conditions. In this article, we describe in detail how to culture, examine and storage cGMP‐iPSCs using reagents, materials and equipment compliant with cGMP standards. © 2020 The Authors.

Implementation of an Optical Fiber Sensor System to Monitor the Response of Reinforced Concrete due to Formwork Removal

The movement of a section of a newly constructed reinforced 2-way suspended floor slab in the Department of Civil Engineering Science at the University of Johannesburg was monitored with an embedded optical fiber sensor (OFS) system during and after construction. The sensor system was used to monitor the strain in the structure before, during and after formwork removal. An OFS system was used due to its inherently distinct advantages such as its unobtrusiveness, lightweight and immunity to corrosion. This paper is concentrated on the findings of the results of these strain measurements with emphasis on the use of Fiber Bragg Gratings (FBG). Strain was measured over a 10 month period in a 5 m section of the suspended floor slab. Three periods during the 10 month period were observed. The first stage was showed 128 micro strain experienced by the structure. During the second stage the formwork was removed and large variations were monitored due to excessive external movement around the structure. The third stage indicated a 10 micro strain change. It was found that an OFS system can accurately measure the movement of reinforced concrete, thereby affording the design engineer to opportunity to monitor the structure during and after construction for large movements that can negatively affect the durability and the serviceability of the structure.
MECHANISMS OF SPECIATION­ A POPULATION GENETIC APPROACH

In his review of White's book on Modes of Speciation, Sewall Wright (249) stated, "The least adequate aspect of 'Modes of Speciation' is the absence of systematic discussion of speciation as a process by which reproductive isolation of a whole population traces to genetic phenomena at the level of the individual. The investigation of such processes is the subject of population genetics. Serious consideration requires mathematical analysis and experiments as well as consideration of the results of speciation to which most attention is paid. " The purpose of this review is to initiate the discussion absent in White's (234) book and much of the speciation literature. I begin with a brief survey of what descriptive population genetics has revealed about the results of speciation. Next, I present a population-genetic classification of modes of speciation followed by a discussion of how theoretical, experimental, and descriptive population-genetic studies can be related to each of the modes. Finally, I discuss the possible relative importance of these modes and outline why it is important for population genetics and speciation theory to become integrated.
Magneto-Electric Dipole antenna for 5-G applications

Magneto Electric (ME) dipoles have been widely studied over the last few years. They are becoming increasingly popular as they allow to generate a wide bandwidth in a printed circuit board (PCB). Nevertheless, their principle of operation requires the use of relatively thick substrates (i.e. about 0. 25λ0, where λ0 is the free-space wavelength) thus resulting in a bulky stack-up. This work tackles this problem by proposing a new type of low -profile ME dipole. The proposed configuration is fed using a slot-coupled microstrip line feed and it employs bandwidth enhancement solutions previously used in metal-only structures. As a result, an ultrathin antenna is achieved which operates over a 20% bandwidth at Ka-band while using an ultrathin dielectric layer being the antenna thickness equal to 0.082 λ0. Moreover, the antenna has a gain of about 5.5 dBi across the entire bandwidth, which makes the proposed design suitable for next generation 5G base stations.

Neural Networks Aided Unscented Kalman Filter for Integrated INS/GNSS Systems

The integrated navigation system consists of Inertial Navigation System (INS) and receiver of Global Navigation Satellite System (GNSS). Aiming to improve position and velocity precision of the INS/GNSS system during GNSS outages, a novel method that combines unscented Kalman filter (UKF) and nonlinear autoregressive neural networks with external inputs (NARX) is proposed (namely NARX aided UKF). The NARX-based module is used to predict the measurements for UKF during GNSS signal outages. A new method for choosing inputs of NARX networks is suggested. This method is based on mutual information criterion (MI) for identifying the inputs that influence each of outputs and lag-space estimation (LSE) for investigating the dependency of these outputs on the past values of inputs and outputs. The performance of the proposed methodology is experimentally verified using data acquired from simulated flight trips, in which the measurement model of MEMS-based INS is used.
An Inventory of Crop Wild Relatives of the United States

The use of crop wild relatives (CWRs) in breeding is likely to continue to intensify as utilization techniques improve and crop adaptation to climate change becomes more pressing. Signifi cant gaps remain in the conservation of these genetic resources. As a fi rst step toward a national strategy for the conservation of CWRs, we present an inventory of taxa occurring in the United States, with suggested prioritization of species based on potential value in crop improvement. We listed 4600 taxa from 985 genera and 194 plant families, including CWRs of potential value via breeding as well as wild species of direct use for food, forage, medicine, herb, ornamental, and/or environmental restoration purposes. United States CWRs are related to a broad range of important food, forage and feed, medicinal, ornamental, and industrial crops. Some potentially valuable species are threatened in the wild, including relatives of sunfl ower (Helianthus annuus L.), walnut (Juglans regia L.), pepo squash (Cucurbita pepo L.), wild rice (Zizania L.), raspberry (Rubus idaeus L.), and plum (Prunus salicina Lindl.), and few accessions of such taxa are currently conserved ex situ. We prioritize 821 taxa from 69 genera primarily related to major food crops, particularly the approximately 285 native taxa from 30 genera that are most closely related to such crops. Both the urgent collection for ex situ conservation and the management of such taxa in protected areas are warranted, necessitating partnerships between concerned organizations, aligned with regional and global initiatives to conserve and provide access to CWR diversity.
Transcriptional Regulation of the Human Hepatic Lipase Gene: Relation to Glucose and Lipid Metabolism

textabstractHepatic Lipase (HL; EC 3.1.1.3) is an extracellular glycoprotein with phospholipase A1 and triacylglycerol hydrolase activity. The human HL protein is encoded by the LIPC gene on chromosome 15q21. Most of this protein is synthesized in the parenchymal cells of the liver and secreted into the space of Disse where it binds to heparin sulfate proteoglycans. Some synthesis of HL was also observed in macrophages. The HL protein is also present in the steroidogenic adrenal glands, ovaries and, in small amounts, in the testes. By using heparin, HL protein is displaced from its binding site. Human HL protein is a homodimer, the monomer has a molecular weight of 65 kDa. In the metabolism of plasma lipoproteins HL plays an important role; it mediates the conversion of high density lipoprotein subfraction 2 (HDL2) to high density lipoprotein subfraction 3 (HDL3), the conversion of intermediate density lipoprotein (IDL) to low density lipoproteins (LDL), and the formation of small dense LDL (sdLDL) from large buoyant LDL. HL has a role in postprandial lipid transport where it facilitates the clearance of remnant lipoproteins by the liver. In adrenals and ovaries the HL enzyme facilitates the delivery of HDL cholesterol for steroidogenesis, at least in the rat. HL expression is determined by genetic, hormonal and nutritional factors, and by body composition. HL activity is associated with a risk for Coronary Artery Diseases (CAD). Whether high HL expression is anti- or pro-atherogenic depends on other genetic or metabolic factors, e.g. concomitant hypertriglyceridemia [1,19]. Humans with visceral obesity and insulin resistance or type 2 diabetes show increased levels of HL expression. How HL gene expression is altered in insulin-resistant conditions is unknown. Relative to the common LIPC C-allele (referring to the C/T polymorphism at the -514 position), carriers of the T-allele have reduced post-heparin HL activity, and the T-allele is associated with dyslipidemia and insulin resistance in healthy controls and in Familial Combined Hyperlipidemia (FCH). In cell culture experiments using human HepG2 hepatoma cells, HL expression was found to be increased by elevated levels of fatty acids and glucose, conditions that prevail in insulin resistance. How these metabolic factors affect HL expression is largely unknown.
Record of Viminella flagellum (Alcyonacea: Ellisellidae) in Italian waters (Mediterranean Sea)

The occurrence of the whip coral Viminella flagellum in Italian waters (Strait of Sicily, Mediterranean Sea), is reported for the first time. The specimens were photographed and sampled at locations situated from 130 to 250 m depth on the north-eastern coasts of Pantelleria Island, by means of a remotely operated vehicle, during a research cruise carried out by ISPRA in May 2010 on-board of the RV ‘Astrea’. A description of the living colonies and other taxonomic characteristics is given. Our finding extends the known geographical distribution of this species in the Mediterranean Sea to the Strait of Sicily.
Low-Profile and High-Gain Linear Polarized Loop Antenna

A loop antenna on top of a metal plate can provide a higher gain than that of a dipole antenna. A low depth profile multi-loop antenna geometry is proposed with a thickness of 0.02 wavelength to the back metal plate. The designed loop antenna is self-matched to the 50-ohm impedance of a source and provides a high directional gain of 8.2 dBi. The antenna gain is increased to 10.0 dBi by using a dual multi-loop geometry. Sample antennas are designed and manufactured for operating at 2250 MHz. The antennas are measured and characterized for the return loss, radiation pattern and gain. The proposed antenna can be used as a wearable antenna in wireless body area network (WBAN), in which the backside radiation is reduced and the antenna impedance characteristics are not affected by the background tissues.
Compressed Lenses via Transformation Optics for Mobile Satellite Communications

In this paper, the design of a volumetric Luneburg lens antenna is described. Transformation optics is used to compress the height of the lens. A moderate compression of 30% is applied to facilitate an all-dielectric realization. A gain of almost 20 dBi is obtained in simulations with a lens diameter of 4 free space wavelengths before compression. The gain of the compressed lens is 1 dB lower and 2 dB higher, compared to conventional Luneburg lenses with the same diameter and height, respectively. The antenna is intended for satellite communications on-the-move through low Earth orbit constellations.
Design and Simulation of Multi Band Compact Microstrip Patch Antenna

Microstrip antennas have been one of very attractive field of research in the recent years. They have become an essential component in many emerging wireless communication applications. Requirements of wide band / multiband operation have resulted in many advanced research in the field of antennas. The paper describes a design and simulation of tri band microstrip patch antenna. The antenna geometry has been loaded with three slots in the radiating element to obtain tri-band operation. The proposed antenna has been designed on 30mils Roggers RT Duroid 5880 substrate having dielectric constant 2.2 and loss tangent 0.0009. The antenna has been simulated using ANSYS HFSS full wave solver using proper boundary conditions. The antenna is resonant at three frequencies 11.65GHz with band of 800MHz, 13.95GHz with band of 1.8GHz and 17.00GHz with band of 600MHz for return loss better than -10dB. The antenna can replace three antennas being used on UAV platform. The designed antenna can be used for Ku band satellite communications in which Rx and Tx operating frequencies are 11.3GHz and 14GHz respectively. The third frequency band can be used for line of sight communications between airborne and ground terminal.
Long-range Acoustical Signals, Phonotaxis, and Risk in the Sexual Pair-Forming Behaviors of Okanagana canadensis and O. rimosa (Hemiptera: Cicadidae)

Abstract The sexual behaviors of Okanagana canadensis (Provancher) and O. rimosa (Say) are described. In northern Michigan, O. canadensis is typically found in coniferous vegetation, such as cedars; whereas O. rimosa frequent deciduous vegetation. In both species, males call from stationary perches, and females approach them. Females have no specialized receptivity signals, but both males and females engage in bouts of wing flicking that may be alternative, low-risk signaling. Mating is brief and involves no elaborate courtship. The Okanagana mating system, characterized by male advertisement and female searching, is contrasted with that of Magicicada spp. , the periodical cicadas of North America, and discussed in the context of relative risks of signaling and searching behaviors.
An Error Identification and Compensation Method of a 6-DoF Parallel Kinematic Machine

Kinematic Calibration is an effective and economical way to improve the accuracy of the six degree-of-freedom (DoF) parallel kinematic machine (PKM), named as Stewart platform, for the large component assembly in aviation or aerospace. The conventional online calibration requires a powerful and complicated control system, whereas the current offline calibration methods are not satisfactory in terms of the compromise between efficiency and accuracy. This paper proposes a semi-online calibration method in which the geometric errors are identified offline and compensated online. The geometric errors are inserted into the inverse kinematic model. Instead of formulating the linear mapping model between geometric errors and the pose error of moving platform, the error model is written as the function of geometric errors with respect to the actuation inputs. Hence, a nonlinear error model is obtained. Without worrying about the identifiability, the error identification equations are converted into an optimization problem and solved by the hybrid genetic algorithm (HGA). In the traditional offline compensation, the identified kinematic parameters are adopted to modify the nominal kinematic model, which is inconvenient when the control system is not transparent to the users. A new control block that calculating the equivalent actuation inputs from the identified errors is added to the control flow. The errors are compensated in an efficient manner. Simulations and experiments are implemented to validate the accuracy, efficiency and convenience of the proposed method. The results indicate that our approach improves position and orientation accuracy of the Stewart platform by 85.1% and 91.0%.
Habitat selection in adult males of Alpine ibex, Capra ibex ibex

Habitat use and selection of 14 Alpine ibex males were studied in the Gran Paradiso National Park. Alpine meadows were always overused and positively selected, because this habitat constituted an important food resource for the ibex. Even if rocks (30%) and stone ravines (22%) were the most frequented habitats in the study area, their use was lower than their availability because they offered few trophic resources. Pastures were used only in spring when the ibexes were looking for those sites just free from snow and with fresh vegetation. Stone ravines, where the ibexes rested in the hottest days, were most used in summer. Rocks were most used in winter: rock-faces are the only sites where the risk of avalanches is low and where it is still possible to find snow-free patches. Larch woods were especially used in winter and spring when it was still possible to find snow-free patches. The home range sizes proved to be influenced by the amount of Alpine meadows and rocks.
The Relationship between Mercury Exposure Indices and Dietary Intake of Fish and Shellfish in Women of Childbearing Age

Women of childbearing age who are susceptible to mercury exposure were studied to understand the relation between mercury intake through fish and shellfish consumption and mercury exposure indices from blood, hair, and urine samples. A total of 711 women of childbearing age from coastal areas with a high concentration of mercury exposure in Korea were studied. Data were collected on demographic characteristics, dietary intake of fish and shellfish using the simple Food Frequency Questionnaire. Mercury concentration was estimated from the collected samples of blood, hair, and urine. The geometric mean of blood methyl mercury concentration of mercury exposure through seafood was 3.06 μg/L for the low tertile, 3.12 μg/L for the middle tertile, and 3.60 μg/L for the high tertile, indicating a clear tendency of blood methyl mercury to increase as the mercury exposure by fish and shellfish intake ascended. For total blood mercury and hair mercury, the middle and high tertiles had higher values than the low. Mercury exposure through fish and shellfish intake is a main factor for an increase of blood methyl mercury concentration in women of childbearing age. More attention needs to be paid to mercury exposure through seafood intake, considering the serious effect mercury concentration has on women of childbearing age.
