Transmission Lines Overload Alleviation: Distributed Online Optimization Approach

The risk of transmission lines overload in the power grid is increasing with the large-scale integration of fluctuating distributed renewable energies. Meanwhile, the requirement for accommodating more distributed resources in the future smart grids promotes the transition from the current highly centralized control structure toward a distributed one. In this article, we propose a distributed corrective control approach to mitigate line overloads in a real-time and close-loop manner. Unlike the conventional centralized approach, only simple computation and local information exchange are required to update the local corrective control action. This makes it possible to mitigate line overloads timely and adapt to the topology changes of grids. Furthermore, the introduction of system measurements and security constraints in the proposed algorithm ensures an effective and secure corrective control without new line overloads. The performance of the proposed distributed approach is demonstrated in the IEEE 14-Bus and 118-Bus systems.
The full-length mitochondrial genome of Cobitis nalbanti (Teleostei: Cypriniformes: Cobitidae)

Abstract The entire mitochondrial genome of Cobitis nalbanti (Teleostei: Cypriniformes: Cobitidae) was analyzed using the primer walking method. The mitogenome was 16,631 bp in length, comprising 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. Its gene order was congruent with those of typical vertebrates. In the phylogenetic tree, C. nalbanti was clearly separated from C. lutheri, which supported the recent taxonomic revision.

Optimal Heating Method for Simultaneous Estimation of Thermal Conductivity and Diffusivity in Transient Hot-Strip Method

This article presents an investigation on transient hot-strip (THS) method for simultaneous estimation of thermal conductivity (<inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula>) and diffusivity (<inline-formula> <tex-math notation="LaTeX">$\alpha $ </tex-math></inline-formula>) based on an inverse parameter estimation technique. Four different heating configurations, such as constant, power law, exponential, and periodic heating, are considered for energizing the THS. In each case, the sensitivity of <inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$\alpha $ </tex-math></inline-formula> is analyzed with regard to its magnitude and existence of correlations between <inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$\alpha $ </tex-math></inline-formula>. Based on the aforesaid criteria, it was found that periodic heating is the best heating configuration for simultaneous estimation of unknown <inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$\alpha $ </tex-math></inline-formula>. Then optimum variables of the best heating configuration were found out based on the D-optimal test. Furthermore, numerical estimations were carried out using pseudoexperimental data to study the applicability of this method for estimation of unknown properties for a wider range of materials. The estimation results of this study reveal that this method is more suited for materials with low-to-medium range thermal conductivity.
Multiple Mode Couplings in a Waveguide Array for Broadband Near-Zero Dispersion and Supercontinuum Generation

We achieve a broadband near-zero dispersion in a thin silicon nitride waveguide array at near-infrared utilizing the multiple mode couplings. Different orders of modes are coupled at four different wavelengths, generating eight zero dispersion wavelengths (ZDWs). The broadband near-zero dispersion profile within 90 ps/nm/km is achieved, spanning over the spectral range of 1350$-$1900 nm. Using the dispersion engineered waveguide array, an octave-spanning supercontinuum is numerically generated with a pump of 100 fs and 200 pJ. The concept of using multiple mode couplings to obtain broadband near-zero dispersion can be applied to other spectral regimes and material platforms as well, by engineering the structural parameters to shift the positions of the ZDWs.
Effects of Corm Dipping in Salicylic Acid or Potassium Nitrate on Growth, Flowering, and Quality of Saffron

Abstract The present research was conducted to find influence of salicylic acid (SA) at 0.5, 1, and 2 mM and potassium nitrate (KNO3) at 250, 500, and 1 000 ppm on reproductive and vegetative parameters, and color characteristics of saffron under field condition. The results indicated the highest a, L, and chroma and the lowest b at 2 mM SA treatment. The highest flowering appearance rate and membrane stability index and the lowest electrolyte leakage were observed at 2 mM SA and to lesser extent at 1000 ppm KNO3. The highest flower number, corolla dry weight, and stigma dry weight was shown in plants treated with SA. Chlorophyll a content and Fv/Fm value increased with the application of 2 mM SA. The data indicated the effectiveness of SA on the growth of saffron.
REFLECTION ON CONSERVATION-RESTORATION PRACTICE TODAY. A EUROPEAN PERSPECTIVE

Contemporary conservation-restoration practice is affected by theoretical and ethical principles and by social factors. They are often discussed separately, but their effect on the processes of conservation-restoration is complex and intertwined. This paper offers an overview of the development of professional codes of ethics in conservationrestoration and as they relate to and inform professional competences. It looks at how ethics and competences are defined and link with professional education. It also discusses relationships with other professions in the preservation of cultural heritage and the need for clarification on the role and obligation of these respective professions. The legal and social issues they generate at a European level are touched upon.
DIETARY ENERGY REQUIREMENT OF CLARIAS GARIEPINUS JUVENILE AT FIXED CRUDE PROTEIN AND ITS EFFECTS ON GROWTH, NUTRIENT PERFORMANCE, HAEMATOLOGY AND BIOCHEMICAL INDICES

This study investigated the optimum dietary energy requirement of African catfish, Clarias gariepinus juveniles fed 35 % crude protein level and the effects on growth, nutrient performance, haematology and biochemical indices. The control diet A had 2800 kcal while, treatments B, C, D and E have 3000, 3200, 3400 and 3600 kcal energy inclusion respectively. Diets were fed to triplicate groups of eight catfish (51 ± 0.56 g) per tank twice daily to satiation for 8 weeks. Significant effects of graded energy levels across diets (p 0.05) recorded across diets in the measured blood parameters and fish organs. Some biochemical parameters like total protein, albumin, cholesterol and high density lipoprotein were not significantly affected by dietary energy inclusion levels, other stress enzyme, like superoxide dismutase was significantly different between diet with diet A and diet E respectively. Though, diet A had the best estimated investment cost ( N 48.30), diet C had the highest values for both net profit ( N 50.68) and benefit cost ratio ( N 1.79). Therefore, feed at 35 % CP would require between 3000 – 3200 kcal/Kg for optimum performance.
Extracellular SPARC improves cardiomyocyte contraction during health and disease

Secreted protein acidic and rich in cysteine (SPARC) is a non-structural extracellular matrix protein that regulates interactions between the matrix and neighboring cells. In the cardiovascular system, it is expressed by cardiac fibroblasts, endothelial cells, and in lower levels by ventricular cardiomyocytes. SPARC expression levels are increased upon myocardial injury and also during hypertrophy and fibrosis. We have previously shown that SPARC improves cardiac function after myocardial infarction by regulating post-synthetic procollagen processing, however whether SPARC directly affects cardiomyocyte contraction is still unknown. In this study we demonstrate a novel inotropic function for extracellular SPARC in the healthy heart as well as in the diseased state after myocarditis-induced cardiac dysfunction. We demonstrate SPARC presence on the cardiomyocyte membrane where it is co-localized with the integrin-beta1 and the integrin-linked kinase. Moreover, extracellular SPARC directly improves cardiomyocyte cell shortening ex vivo and cardiac function in vivo, both in healthy myocardium and during coxsackie virus-induced cardiac dysfunction. In conclusion, we demonstrate a novel inotropic function for SPARC in the heart, with a potential therapeutic application when myocyte contractile function is diminished such as that caused by a myocarditis-related cardiac injury.

06/September/2019 Approved: 19/April/2020 ABSTRACT A total of 320 13-weeks-old pullets were weighed and randomly allocated to treatments comprised by four levels of crude glycerin (0, 3, 6 or 9%) and two levels of ME (metabolizable energy, difference of 100 kcal/kg) in the diets growing (14 to 17 weeks of age), pre-lay and pre-peak (low: 2750, 2800 and 2750 kcal/kg and high: 2850, 2900 and 2850 kcal/kg, respectively). During the study, body weight was registered until 30 weeks of age, feed intake, egg weight and egg-production for each repetition and for individual hens were measured every week. The information was analyzed through a completely
Enhancing Forest and Shrubland Mapping in a Managed Forest Landscape with Landsat–LiDAR Data Fusion

ABSTRACT: Contemporary losses of early-successional young forest and shrubland habitat have resulted in range-wide population declines of numerous wildlife species, establishing shrubland conservation as a high priority in the eastern United States. However, the extent and spatial distribution of shrubland habitat is lacking for many locations. The Landsat program is an important resource for quantifying vegetation and land cover, but recent applications indicate that divergent structural characteristics between certain feature classes, such as vegetation height, are not readily captured by spectral response alone. The fusion of Landsat imagery with light detection and ranging (LiDAR) data at the pixel level into existing supervised classification schemes may offset this discrepancy. We used multispectral images from Landsat 8′s Operational Land Imager (OLI) to compare Landsat OLI and Landsat OLI-LiDAR fusion data in the classification of 10 vegetation and land cover types across a ∼5000 km2 area in southeastern Ohio at the native 30-m Landsat resolution. Fusion data produced a 12% increase in overall classification accuracy from the Landsat OLI model and met minimum mapping accuracy standards in remote sensing. Importantly, LiDAR textural bands in the fusion model improved discrimination of forest and shrubland classes with the most dramatic difference manifesting as a 75% increase in shrubland user's accuracy. We demonstrate that Landsat OLI–LiDAR fusions are valuable for accurate shrubland mapping in forestlands. Additionally, we show that vegetation and land cover modeling can be easily integrated into existing wildlife monitoring programs by simultaneously sampling vegetation classes and wildlife communities from similar locations.

The role of profitability in mediating company ownership structure and size of firm value in the pharmaceutical industry on the Indonesia stock exchange

The purpose of this study was to examine the effect of ownership structure, firm size, and profitability on firm value. The research model was built by placing profitability measured by Return on Equity (ROE) as a mediating variable on the effect of ownership structure and firm size on the firm value measured by Price to Book Value (PBV). The study was conducted on the Pharmaceutical Industry in the Indonesia Stock Exchange for the period 2013-2018, with a total sample of 42 obtained by purposive sampling technique and analyzed by path analysis method. The results showed that foreign ownership had a significant positive effect on profitability but did not have a significant positive effect on firm value. Managerial ownership has no significant positive effect on profitability and no significant negative effect on firm value. Institutional ownership does not have a significant positive effect on profitability and firm value. The firm size has a significant positive effect on profitability but does not have a significant positive effect on firm value. Profitability has a significant positive effect on firm value. The role of profitability as mediation in this study was tested by calculating the value of sobel. The results show that profitability is able to mediate foreign ownership of firm value with a sobel value of 2.181 and profitability is able to mediate the firm size against firm value with a sobel value of 2.159.
Efficient and Privacy-Preserving Authentication Protocol for Heterogeneous Systems in IIoT

The Industrial Internet of Things (IIoT) is expected to provide a promising opportunity to revolutionize the production operation of the existing industrial systems by leveraging smart devices. Due to the untrusted nature of communication channels, ensuring data authenticity is a critical challenge. Besides, devices’ privacy and communication heterogeneity raise crucial concerns about the IIoT applications since the existing authentication protocols for the IIoT environment face the potential threats of privacy leakage and cannot achieve secure communication between heterogeneous industrial systems. To address these challenges, this article proposes an efficient privacy-preserving authentication protocol for heterogeneous systems in IIoT using proxy resignature. The presented protocol not only provides heterogeneous communication between ID-based and certificateless-based cryptosystems but also achieves various security requirements. The security of our protocol has been proven based on the extended Computational Diffie–Hellman (eCDH) assumption in the random oracle model. The experimental simulation demonstrates that our protocol is feasible for the IIoT-based environment.
A Wideband Circular-Polarized Beam Steering Dielectric Resonator Antenna Using Gravitational Ball Lens

This communication proposes a wideband circular-polarized (CP) beam steering dielectric resonator antenna (DRA) using a gravitational ball lens. It offers a passive means for wall or ceiling mounted base station antennas to adjust their patterns by the gravity of ball lenses. This novel antenna concept overcomes the difficulties of achieving wideband axial ratio versus the pattern reconfigurability of the existing antennas. The operation of the ball lens has been intensively studied. It is found that the ball lens provides 1.2 dB antenna gain enhancement, whereas enabling beam tilting via energy coupling to the offset direction. As a demonstration, a codesign of DRA and ball lens has been developed at 2.4 GHz, achieving 42% impedance bandwidth, 39% axial ratio bandwidth, and ±40° beam steering. Reasonable agreement between simulated and measured results is observed. The proposed DRA provides a low-cost solution for base stations to be mounted at an angle and effectively cover the indoor users.
Comparative foraging and diving behaviour of coexisting breeding and non-breeding King Penguins (Aptenodytes patagonicus) in Tierra del Fuego, Chile

ABSTRACT Breeding status directly affects the at-sea behaviour of seabirds, resulting in marked differences between breeding and non-breeding birds. In this study, we report for the first time the foraging and diving behaviour of coexisting incubating, courting and non-breeding King Penguins (Aptenodytes patagonicus) at a recently established colony in Tierra del Fuego, Chile, to determine differences in (1) the number and duration of the foraging trips, (2) time spent at sea and on land, and (3) diving performance and foraging success. We obtained data from four incubating, five courting and three non-breeding penguins equipped with time–depth recorders during November and December 2014. Incubating birds performed a single but long trip (8.1 ± 1.9 days), while courting birds performed one or two trips of intermediate duration (2.3 ± 0.8 days) and non-breeders made multiple short trips (0.6 ± 0.1 days). Courting birds spent a significantly greater proportion of their time on land than the other birds. Incubating birds performed the deepest and longest dives and had the highest diving efficiency, while non-breeders performed the shallowest and shortest dives and exhibited low diving efficiencies, suggesting that birds are utilising different foraging areas. These results indicate that incubating, courting and non-breeding King Penguins, although coexisting temporally at the same colony, differentially adjust their foraging and diving behaviour, most likely to accomplish their specific social and energetic demands.
Asymptotic System Performance over Generalized Fading Channels with Application to Maximal-Ratio Combining

—The performance of wireless communications sys- tems is affected by many aspects of the fading phenomenon, such as clustering, nonlinearity, scattered waves, and line of sight. Even though several fading models exist which address a multitude of propagation conditions, in many cases the fading statistics or the associated system performance cannot be obtained in a closed form. In such cases, it is difﬁcult to decipher how each physical aspect of fading impacts the system performance. In this work, we propose a uniﬁed asymptotic characterization at high signal-to-noise ratio to obtain simple, general closed-form expressions for the diversity and coding gains of essential performance metrics, namely, symbol error rate and outage probability. We cover generalized propagation conditions and all the referred fading aspects. The analysis is further extended to investigate the performance of multibranch maximal-ratio combining. Capitalizing on the fact that the asymptotic channel distribution around the origin fully determines the diversity and coding gains, our results provide new insights into how each physical aspect of fading ultimately affects the wireless system performance.
Value of Information Sharing in Online Retail Supply Chain Considering Product Loss

This article investigates the impact of information sharing on supply chain performance when considering the product loss in e-commerce. By characterizing four information sharing mechanisms, we analyze the optimal information sharing decisions on bullwhip effects and inventory costs in near/far-distance e-commerce contexts. The analytical results reveal the vital significance of product loss information to bullwhip and cost reductions. Particularly, in far-distance e-commerce, if the online retailer only shares the demand information, the wholesaler may suffer an even worse bullwhip effect than that without information sharing. Moreover, the impacts of product loss reveal the supply chain characteristic difference between fragile products and ordinary products in e-commerce. Our research generates important managerial insights regarding supply chain management and provides practical guidelines for online retailers and wholesalers optimizing their information sharing decisions according to different e-commerce contexts.
Estimation of Aboveground Tree Biomass Toona Sureni and Coffea Arabica in Agroforestry System of Simalungun, North Sumatra, Indonesia

Latifah S, Muhdi, Purwoko A, Tanjung E. 2018. Estimation of aboveground tree biomass Toona sureni and Coffea arabica in agroforestry system of Simalungun, North Sumatra, Indonesia. Biodiversitas 19: 670-675. Agroforestry is an ecologically and environmentally sustainable land use that offers great promise to carbon (C) sequestration. Forests play a significant role in reducing greenhouse gas emissions through maintaining current carbon stores and by increasing the rate of carbon sequestration. Vegetation carbon stocks are necessary to be quantified to evaluate the carbon sequestration potential in the ecosystem. Reasonable methods for estimating tree biomass and carbon storage on forest land are increasingly crucial given concerns of global climate change. This study aimed to evaluate C sequestration potential by agroforestry in North Sumatra Indonesia. This study was conducted at the Agroforestry system in Aek Nauli, Simalungun District, North Sumatra. Data collection for primary data was done through a field survey. The present study was carried out to determine above ground tree biomass of Toona sureni (Blume) Merr and Coffea arabica. Data retrieval of T. sureni and C. arabica was done by non-destructive sampling by measuring the diameter at breast height (dbh). The results showed that the potential of average above-ground biomass and carbon storage of T. sureni and C. arabica was 6.25 t ha-1 and 2.88 C t ha-1, respectively. Total aboveground biomass of Toona sureni and C. arabica in the study area was 93.75 ton, while total of carbon storage was 43.16 ton
Effects of dietary nano and macro iron oxide (Fe2O3) on the growth, biochemical, and hematological profiles of African catfish (Clarias gariepinus) fingerlings

ABSTRACT Effects of nano and macro iron oxide as dietary iron sources on the growth, hematological, and biochemical characteristics of African catfish, Clarias gariepinus, fingerlings have been studied. Conventional basal feed was supplemented with nFe2O3 and Fe2O3 as treatments T1 and T2 (each at 0.0, 0.2, 0.4, 0.8, 1.2, and 1.6 g/kg supplementation levels) and given to C. gariepinus fingerlings (initial average weight and length 5.01 ± 0.80 g and 7.0 ± 0.53 cm respectively) for 7 weeks. After 7 weeks, the highest percent weight gains of 395.6% for T1 and 767.4% for T2 occurred simultaneously at the supplementation level of 0.4 g Fe kg−1 dry feed of both treatments, while the highest value for the control was 332.5%. Iron accumulations in liver were 2.727, 1.443, and 1.225 ppm, and red blood cell counts were 2.3, 6.0, and 7.0 x 1012/l for the same treatments. Supplementation of iron oxide in both nano and macro forms significantly improved the growth and health indices of C. gariepinus up to a concentration of 0.4 g Fe kg−1 dry feed. Also macro iron oxide was more effective than the nano form in enhancing fish growth within the supplementation levels (0.2−1.6 g kg−1) considered.
