Dual-Carrier 1-Tb/s Transmission Over Field-Deployed G.654.E Fiber Link Using Real-Time Transponder

SUMMARY We demonstrated 1-Tb/s-class transmissions of field- deployed large-core low-loss fiber links, which is compliant with ITU-T G.654. E, using our newly developed real-time transponder consisting of a state-of-the-art 16-nm complementary metal-oxide-semiconductor (CMOS) based digital signal processing application-specific integrated circuit (DSP-ASIC) and an indium phosphide (InP) based high-bandwidth coherent driver modulator (HB-CDM). In this field experiment, we have achieved record transmission distances of 1122 km for net data-rate 1-Tb/s transmission with dual polarization-division multiplexed (PDM) 32 quadrature amplitude modulation (QAM) signals, and of 336.6 km for net data-rate 1.2-Tb/s transmission with dual PDM-64QAM signals. This is the first demonstration of applying hybrid erbium-doped fiber amplifier (EDFA) and backward-distributed Raman amplifier were applied to terrestrial G.654. E fiber links. We also confirmed the stability of signal performance over field fiber transmission in wavelength division multiplexed (WDM) condition. The Q-factor fluctuations respectively were only less than or equal to 0.052 dB and 0.07 dB for PDM-32QAM and PDM-64QAM
Optimum stocking density for Parachanna obscura larvae fed at its optimum ration

Two experiments were conducted during 15 days respectively in re–circulating system composed of 15 plastic tanks containing 20L of water each. This study aims at estimating optimum feeding rate and stocking density for efficient growth, food utilization and survival rate of Parachanna obscura larvae (initial body weight = 0.1 ± 0.0 g and 0.15 ± 0.13 g). In the first experiment, five food rations (5, 10, 20, 25 and 30% of body weight per day) were tested in triplicate. Specific Growth Rate (SGR) and Feed Efficiency (FE) of larvae fed different rations varied significantly (P<0.05). Best SGR and FE were obtained with rations from 5 to 10% of body weight. Two mathematical models were used to analyse the relationships between feeding level and SGR. Optimum and maximum rations are 8.13% and 25% of body weight respectively. In the second experiment, five stocking densities (5, 20, 35, 50 and 65 larvae/L) were assigned in triplicate. Fish were fed manually with ration 8.13% of body weight. Results showed that SGR and FE obtained with different densities varied significantly (P<0.05). Highest final body weight and survival rate of fish were obtained with stocking density 20/L of water. Moreover, best SGR and FE were observed in larvae stocked at density 20 larvae/L (P<0.05). Thus, optimum stocking density of P. obscura fry (initial body weight = 0.15 ± 0.13 g) is 20/L.

Life in the tropical suburbs: Food type partitioning among sympatric African house snakes of the genus Lamprophis (Colubridae)

The food niche partitioning of four species of house snakes (Lamprophis fuliginosus, L. olivaceus, L. lineatus, and L. virgatus) was studied in suburban areas of south‐eastern Nigeria, West Africa. Snakes were captured in the field, and their stomach contents were obtained by forced‐squeezing of the ingested bolus. Pseudo‐community analysis and Monte Carlo simulations, by two different algorithms, were used to investigate whether the community under study was randomly assembled along the trophic niche axis. Four hundred and thirty snake individuals were captured: 52 out of 133 L. fuliginosus (32.1%), 31 of 126 (24.6%) L. lineatus, 30 of 108 (27.8%) L. virgatus, and 20 of 63 (31.7%) L. olivaceus had identifiable food contents in the stomach. Lamprophis fuliginosus appeared as the more generalist species, L. lineatus showed some preference for lizards and frogs, L. virgatus for small mammals (rodents and shrews), and L. olivaceus for nestling birds and small mammals. However, null models showed that the community organization was random along the food niche axis by both the randomization algorithms used in this paper. Thus, we concluded that these four snake species do not partition either the quality or the number of the available resources.
Access Plan Recommendation Using SQL Queries Similarity

: Plan reuse is a technique of databases optimization, the main purpose of which is to reuse old access plans stored in the database to execute future queries instead of generating new plans. To carry out its task, the optimizer needs to identify similarity between new and old queries. Questions such as which techniques are needed and which SQL query representation is best to produce accurate similarity estimation remain poorly addressed. The main goals of this work is to propose an approach for access plan recommendation using 4 SQL queries representations and clustering techniques to identify similarity between queries. We study SQL queries similarity, at the intentional level by considering the uninterpreted SQL sentences; therefore SQL queries are represented to TF-IDF and N-GRAM. Then, feature selection algorithms are used to identify the most signiﬁcant descriptors in the feature space. Next, clustering is applied using partitionning clustering, density based clustering and competitive learning based clustering. Finally, a access plan is recommended to the optimizer. Results show that the use of feature selection process is relevant to our work especially for TF-IDF representation while the most accurate and efﬁcient clutsering is obtained with k-means algorithm.
Novel Human Endogenous Sequences Related to Human

Endogenous retrovirus-related sequences exist within the normal genomic DNA of all eukaryotes, and these endogenous sequences have been shown to be important to the nature and biology of related exogenous retroviruses and may also play a role in cellular functions. To date, no endogenous sequences related to human immunodeficiency virus type 1 (HIV-1) have been reported. Herein we describe the first report of the presence of nucleotide sequences related to HIV-1 in human, chimpanzee, and rhesus monkey DNAs from normal uninfected individuals. We also present the isolation and characterization of two of these endogenous HIV-1-related sequences, EHS-1 and EHS-2. With use of low-stringency Southern blot hybridization, complex banding patterns were detected in human DNA with 5' and 3' HIV-1-derived probes. When an HIV-1 env region probe was used, we detected a less complex, conserved banding pattern in human DNA as well as a related but distinct banding pattern in chimpanzee and rhesus monkey DNAs. EHS-1 and -2 were cloned from normal human genomic DNA libraries by using the env region probe. Clone EHS-1 shows sequence similarity with the domain of the envelope cellular protease cleavage site of HIV-1, while EHS-2 has sequence similarity to the overlapping reading frame for Rev and gp4i. Stringent hybridization of EHS-1 back to primate genomic DNA indicates two distinct EHS-1 loci in normal human DNA, an identical band pattern in chimpanzee DNA, and a single locus in rhesus monkey DNA. Likewise, EHS-2 is present as a single highly conserved locus in all three species. An oligonucleotide derived from EHS-2 across a region of near identity to HIV-1 detects a complex banding pattern in all primates tested similar to that seen with the 3' HIV-1 probe. These data suggest that most of the HIV-1-related sequences identified in primate DNA share a common core of nucleic acid sequence found in both EHS-2 and rev and that some of these H1V-1-related sequences have additional larger regions of sequence similarity to HIV-1.
Communication between Coroutines on Sunway Many-core Platform

Communication between parallel programs is an indispensable part of parallel computing. SW26010 is a heterogeneous many-core processor used to build the Sunway TaihuLight supercomputer, which is well suited for parallel computing. Our team is designing and implementing a coroutine scheduling system on SW26010 processor to improve its concurrency, it is very important and necessary to achieve communication between coroutines for the coroutine scheduling system in advance. Therefore, this paper proposes a communication system for data and information exchange between coroutines on SW26010 processor, which contains the following parts. First, we design and implement a producer-consumer mode channel communication based on ring buffer, and designs synchronization mechanism for condition of multi-producer and multi-consumer based on the different atomic operation on the MPE (management processing element) and the CPE (computing processing element) of SW26010. Next, we design a wake-up mechanism between the producer and the consumer, which reduces the waiting of the program for communication. At last, we test and analyse the performance of channel in different numbers of producers and consumers, draw the conclusion that when the number of producers and consumers increases, the channel performance will decrease.
From Online to Non-i.i.d. Batch Learning

This paper initializes the study of online-to-batch conversion when the samples in batch learning are not i.i. d. Our motivation originated from two facts. First, sample sets in reality are seldom i.i. d. , thus preventing the application of the existing conversions. Second, the online model of learning permits an adversarial stream of samples that almost for sure violates the i.i. d. assumption, raising the possibility of adapting an online algorithm effectively to learn from a non-i.i. d. sample set. We present a set of techniques to utilize an online algorithm as a black box to perform batch learning in the absence of the i.i. d. assumption. Our techniques are generic, and are applicable to virtually any online algorithms on classification. This provides strong evidence that the great variety of known algorithms in the online-learning literature can indeed be harnessed to learn from sufficiently-representative non-i.i. d. samples.
REVIEW OF RECENT TECHNIQUES FOR EXTRACTIVE TEXT SUMMARIZATION

In the view of a significant increase in the burden of information over and over the limit by the amount of information available on the internet, there is a huge increase in the amount of information overloading and redundancy contained in each document. Extracting important information in a summarized format would help a number of users. It is therefore necessary to have proper and properly prepared summaries. Subsequently, many research papers are proposed continuously to develop new approaches to automatically summarize the text. “Automatic Text Summarization” is a process to create a shorter version of the original text (one or more documents) which conveys information present in the documents. In general, the summary of the text can be categorized into two types: Extractive-based and Abstractive-based. Abstractive-based methods are very complicated as they need to address a huge-scale natural language. Therefore, research communities are focusing on extractive summaries, attempting to achieve more consistent, non-recurring and meaningful summaries. This review provides an elaborative survey of extractive text summarization techniques. Specifically, it focuses on unsupervised techniques, providing recent efforts and advances on them and list their strengths and weaknesses points in a comparative tabular manner. In addition, this review highlights efforts made in the evaluation techniques of the summaries and finally deduces some possible future trends.
Aphanomyces as a Cause of Ulcerative Skin Lesions of Menhaden from Chesapeake Bay Tributaries

Abstract During the summer and fall of 1997, an unusually high prevalence of skin lesions in fishes from Chesapeake Bay tributaries as well as two fish kills in the Pocomoke River stimulated significant public concern. Atlantic menhaden Brevoortia tyrannus were the most frequent target of the acute fish kills and displayed skin lesions that were attributed to the presence of the toxic dinoflagellate Pfiesteria piscicida. Hence, the penetrating skin ulcers so commonly found in this species are now widely viewed by the general public and some scientists as Pfiesteria-related and to be caused by exposure to Pfiesteria toxin. We examined, histologically, 121 menhaden with these ulcers collected from both Maryland and Virginia waters of the Chesapeake Bay in 1997 and 31 from the Pocomoke and Wicomico rivers in 1998. All of the deeply penetrating ulcers, as well as raised lesions (with or without eroded epithelium), were characterized by deeply penetrating fungal hyphae surrounded by chronic, granulomatous infl.
Registration of steele-ND/ND 735 wheat recombinant inbred lines mapping population.

Steele-ND/ND 735 (Reg. No. MP-1, NSL 462030), a hard red spring wheat (Triticum aestivum L.) (HRSW) recombinant inbred lines (RILs) population, was developed and released by the North Dakota State University (NDSU), Fargo, ND, in 2008. This mapping population is composed of 129 F 29 RILs. The Steele-ND/ND 735 RILs population has been used extensively to study the genetics of resistance to tan spot [caused by Pyrenophora tritici-repentis (Died.) Drechs. ], Stagonospora nodorum blotch [caused by Phaeosphaeria nodorum (E. Muller) Hedjarroud], Septoria tritici blotch [caused by Mycosphaerella graminicola (Fuckl) J. Schrot. in Cohn], and Fusarium head blight (caused by Fusarium graminearum Schwabe) and to map the resistance genes and quantitative trait loci underlying the above traits. The genetic marker data encompass hundreds of polymorphic Diversity Array Technology (DArT) and simple sequence repeats markers that were collected at Diversity Arrays Technology, Yarralumla, Australia, and NDSU, respectively.
ASSETS: G: BrailleBlocks: Braille Toys for Cross-Ability Collaboration

Braille literacy rates are dropping among blind students in the United States, prompting what experts have described as the “Braille Literacy Crisis” [15]. However, for these students, Braille remains crucial for literacy and employment [19]. BrailleBlocks is a system to motivate blind or visually impaired children to learn Braille with a sighted parent. BrailleBlocks includes a set of wooden blocks, representing Braille cells, and an interface with games for parents. We conducted user studies with five sighted parents and six blind visually impaired children. Children preferred games with sound effects, specifically Hangman and the Animal Name Game. Parents commended the system as a spelling tool and found the screen display of Braille letters to be a helpful reference. Children created new ways to use the system beyond the games we provided, such as for storytelling and by stacking blocks into structures. We identified concrete ways to improve the system, including generating progress reports for parents and developing a portable version.
Interactive Shared Mixed Reality on Mobile Devices

Popularity of augmented reality games like ‘Pokémon Go’ has proved that technologies like virtual and augmented reality are ready for the big time. There has been a number of augmented/mixed reality apps for mobile platforms where a user’s experience is generally isolated or individual. In this paper, we discuss about the concept of interactive shared mixed reality using mobile devices where multiple users can share the same augmented experience from their own devices. We wish to demonstrate the concept by means of a multiplayer mixed reality game. Shared mixed reality on mobile devices has specific challenges which are discussed in this paper. Besides, in order to provide unified experience for all the participating users, the system requires special capabilities and protocols. In this paper, we are proposing a framework for shared mixed reality using mobile devices. The purpose of this framework is to facilitate development of similar interactive shared mixed reality applications for mobile devices.
Impact of Ownership, Competition, and Governance on Efficiency of Banking Sector in Pakistan

Financial sector of Pakistan undergoes massive reforms in the 90s. The primary aim of reforms is to privatized state-owned institutions, abolish entry barriers for new players, which consequently increase the efficiency of the whole system. This study uses an unbalanced panel of 21 commercial banks listed at Pakistan stock exchange over the period of 2000 to 2017 from Bankscope and Bloomberg. This research aims to measure the effect of ownership, competition and, governance on banks efficiency. A graphical representation shows an increasing trend in both foreign ownership and efficiency over the sample period. I found a higher efficiency of private banks in comparison to state-owned counterparts. The empirical analysis suggests that an increase in foreign ownership and institutional ownership impact positively on all measures of efficiency. The relationship between competition and efficiency supports “competition-efficiency hypothesis” and proposed regulatory measures to deregulate the market further. Additionally, banks who score high on governance measures tend to be more efficient than those with low governance scores. These findings imply that there is a need to regulate the bigger banks and ease the market entry for foreign and institutional owners to promote governance practice and hence efficiency. Key-Words: Bank, Ownership Structure, Competition, Governance, Efficiency, Data Envelopment analysis.
Design of Slow Wave Microstrip Patch Antenna Array

This paper presents the design of a Slow wave Micro-Strip (SMS) patch antenna array with two different configurations. The main difference is presented in the radiation patterns of these two configurations. The first array is designed to radiate towards a single user, while the second radiates equally towards two distant users. The SMS technique is applied on the developed arrays in order to reduce their overall surface area. This technique is based on the slow wave effect created using a double layer Roger stack, with an artificially modified bottom layer. The artificial layer is hosting rows of metallic via holes having a cylindrical shape. The insertion of these metallic via holes increases the effective permittivity of the substrate layer, thus, a slower wave propagation is obtained. Consequently, a lower wavelength and smaller antenna size are achieved. The proposed SMS 2×2 antenna arrays resonate around the Industrial, Scientific and Medical (ISM) radio bands at 2.45 GHz and targeting the Wi-Fi and Bluetooth applications. A good agreement between the simulated and measured results is achieved with up to 57 % size reduction for both configurations.
DISCOVERING RANSOMWAREBEHAVIOR BY HOST-BASED APPROACH

Numerous researchers have discovered multiple types of ransomware that has been rampaging in cybersecurity which is the main concern for business companies where most of their data has been digitalized. However, the main problem in detecting this type of malware, where it is known as sophisticated behavior is quite challenging since it capable to do encryption in file activity system and hide its malicious activity in computer host. Nevertheless, previous researcher also has done major contribution in discovering its pattern and behavior of ransomware and provide numerous solutions in detecting this malware. This paper will be focusing on ransomware behavior during normal file activity system by using host-based approach experiment. The design of the experiment and dataset collection are one of the main important in this experiment for analyzing the ransomware behavior using available tools and software. Then, the behavior of the ransomware will be saved as log file for in-depth analysis. Finally, the results from the experiment will be tabulated and discussed further before the conclusion of the experiment.
Genetic variation in potential kernel size affects kernel growth and yield of Sorghum

Large-seededness can increase grain yield in sorghum [Sorghum bicolor (L.) Moench] if larger kernel size more than compensates for the associated reduction in kernel number. The aim of this research was to investigate kernel filling characteristics associated with the high kernel weight of KS115 germplasm and consider implications for grain yield improvement. Germplasm with a twofold range in potential kernel size was grown in two field experiments. In both experiments, a large-seeded hybrid based on KS115 yielded significantly more grain than a normal-seeded hybrid with the same female parent. Genotypic differences in final kernel weight were associated with both an increased rate and extended duration of kernel filling. A high kernel filling rate was associated with a high rate of increase in kernel water content and kernel volume, which resulted in large maximum water content and volume per kernel. The long kernel filling duration of KS115-based germplasm was associated with an extended duration of the period of rapid water uptake into the kernel following the onset of rapid dry mass accumulation in the grains. For this particular germplasm, this was likely due to the presence of large ovaries before fertilization. Because of a trade-off between potential kernel weight and number, prolonged duration, rather than an increased rate of kernel filling, appeared to be the main mechanism through which large-seededness of KS115 could increase grain yield.
The relationship between the understanding of philosophy of sufficiency economy and the living standard: the case study of sufficiency economy community in lower northern region of Thailand

The purpose of this research paper is to find the relationship between the knowledge of “Sufficiency Economy Principles” and the quality of life of the households. It is postulated that, the higher the level of the knowledge of the principles that the household has acquired, the better the quality of life of the household as measured by family’s income. A number of survey questionnaires have been sent out to families in rural areas in Northern part of Thailand. The sample families are from two types of village: one is under a pilot project called “sufficiency economy village”, the other is not. The sampled data have been used to estimate the parameters of the logit model. The results indicate that, the level of education, and the knowledge of the principles have significant influence on family’s income. The location of the family (i.e., whether or not it is in the Philosophy of Sufficiency Economy prototype village), however, has no significant relation with the family’s income. Author`s Note: The authors would like to thank to the Research Institute of Rangsit University for providing financial support for this research project.
An Accurate Finite-Difference Method for 1-D Wave Problem Based on a Pre-Concerted Grid

An accurate numerical method is proposed for the solution of 1-D initial-boundary value wave problem. It is of finite-difference type, where a pre-concerted grid is constructed using a specific time discretization. The ultimate goal is the minimizing of global error. Keeping of the stability-accuracy balance is the key element of the new proposal. It is particularly useful in case of large integration domains. The most important part of the method is implemented and tested in Matlab, and the results are compared with those of classic difference method.
