Effect of sugarcane silage on productive parameters of replacement Holstein-Friesian heifers

Objective. Measure the productive parameters of Holstein-Friesian females from weaning to 470 days old, comparing feeding through sugarcane silage (SCS) and corn silage (CS) in a concentrated fodder ratio of 70:30. Materials and methods. Twenty-eight post-weaning calves were used, with an average age of 80±16 days old and an initial weight of 79.5±12.9 kg. The T-Student test was used for the comparison of means, where calves were divided into two groups of 14, one for each treatment. The body weight BW (kg), wither height WH (cm), body condition BC (1 to 5 scale), daily weight gain DWG (kg) and feed conversion FC (kg) was measured every 30 days. Results. Differences were found between treatments, where heifers fed with SCS showed better BC (3.12), FC (7.4) as compared to the CS treatment. No significant differences were found in terms of DWG (0.666 and 0.743 kg/d). Conclusions. Feeding based on sugarcane silage allows for an improved body condition and feed conversion of animals having with this an acceptable and cost-effective production performance in the raising of dairy replacements.
High-Gain and High-Efficiency GRIN Metamaterial Lens Antenna With Uniform Amplitude and Phase Distributions on Aperture

A gradient index (GRIN) metamaterial lens antenna with extremely high gain and high aperture efficiency is presented. The proposed antenna is much more advantageous in terms of gain and aperture efficiency without compromising in simplicity and stability. The gain and aperture efficiency are improved by using a new method to design the GRIN lens for a hybrid mode, which possesses both uniform amplitude and phase distributions on the aperture. At the center of frequency band (14.25 GHz), the proposed antenna achieves a gain of 26.6 dBi, which corresponds to aperture efficiency greater than 90%.
Rotation Entropy-Based Vortex Identification

The information measure and detection for vortex in flow field is a challenging issue. This paper presents a new information measure for flow field called rotation entropy to highlight vortex regions in flow field. Rotation entropy is the statistical quantity of vectors in sample region around a point, and indicates the rotation information of the region. The properties of rotation entropy are discussed in this paper. Based on these properties, a vortex detection algorithm is proposed. In this algorithm, the linear fit of points in radial direction of the local maximum is applied to determine vortex. The experimental results show that rotation entropy highlights the rotation information of the field, and the algorithm proposed can exactly identify the vortex in flow field.
Diagnosing diabetes: a new paradigm.

Diabetes mellitus is an important international health concern due to its increasing prevalence and high associated social and economic costs. In the UK, over 2.7 million people have diabetes, predicted to rise to 4 million people by 2025.1 Approximately 10–15% of the hospital inpatients are affected by diabetes, and ∼10% of healthcare spending is directly related to diabetes and its attendant complications. Diabetes contributes significantly to mortality from cardiovascular disease and is associated with a life expectancy shortened by up to 20 years in people with Type 1 diabetes (T1D) and 10 years in Type 2 diabetes (T2D). 1 Diagnosis of diabetes has been dependent on glucose tests for a number of years, and screening relied on fasting glucose values, augmented by oral glucose tolerance testing (OGTT) if fasting glucose levels were abnormal. Recently, a World Health Organisation (WHO) consultation has concluded that glycated haemoglobin (haemoglobin A1c or HbA1c) can be used to diagnose diabetes (Table 1). 2 The rationale for this is the observation that the cut point of 6.5% (48 mmol/mol) correlates with a significant increase in risk for the development of diabetic retinopathy, and the correlation is stronger than that for fasting plasma glucose.3 HbA1c reflects prevailing glycaemia over the preceding 2 or 3 months, so may not be elevated if glucose levels have risen acutely, or where there is abnormal haemoglobin metabolism. Therefore, clinicians need to …
P-Channel Nonvolatile Flash Memory With a Dopant-Segregated Schottky-Barrier Source/Drain

A p-channel dopant-segregated-Schottky-barrier (DSSB) device based on a SOI FinFET structure is proposed for silicon-oxide-nitride-oxide-silicon type Flash memory, providing the feasibility of bit-by-bit operation through the aid of a symmetric program/erase operation. This concept is based on utilizing injected holes due to enhanced Fowler-Nordheim tunneling probability triggered by the sharpened energy band bending at the DSSB source/drain junctions as a programming method and the tunneled electrons from a silicon channel as an erasing method. As a result, a threshold voltage window of nearly 4 V and good data retention are achieved within a P/E time of 3.2 μs.
System G Distributed Graph Database

Motivated by the need to extract knowledge and value frominterconnected data, graph analytics on big data is a veryactive area of research in both industry and academia. Tosupport graph analytics efficiently a large number of in mem-ory graph libraries, graph processing systems and graphdatabases have emerged. Projects in each of these cate-gories focus on particular aspects such as static versus dy-namic graphs, off line versus on line processing, small versuslarge graphs, etc.While there has been much advance in graph processingin the past decades, there is still a need for a fast graph pro-cessing, using a cluster of machines with distributed storage.In this paper, we discuss a novel distributed graph databasecalled System G designed for efficient graph data storage andprocessing on modern computing architectures. In particu-lar we describe a single node graph database and a runtimeand communication layer that allows us to compose a dis-tributed graph database from multiple single node instances.From various industry requirements, we find that fast inser-tions and large volume concurrent queries are critical partsof the graph databases and we optimize our database forsuch features. We experimentally show the efficiency ofSystem G for storing data and processing graph queries onstate-of-the-art platforms.
On Surveillance Quality of Sensor Networks with Faulty Sensor Nodes

In this paper we explore the impact of faulty sensor nodes on quality of surveillance. The faulty behavior of sensor nodes may result from several situations, such as malfunctions due to low-cost hardware, environmental interference, or battery depletion. Two major fault models of sensor nodes including false alarm and detection miss are addressed. To enhance the quality of surveillance, a data aggregation scheme is employed to increase the credibility of the sensing reports. Because the energy resource on sensor nodes is scarce, how to determine the degree of data aggregation to achieve the desirable quality, while the overall system lifetime can be prolonged, is an important issue. We define the quality of surveillance considering the system false alarm and the system detection miss to provide a deployment strategy for surveillance. Furthermore, the improvement of the data aggregation scheme and the related metrics on quality of surveillance are analyzed through simulations.
Femto-to-Femto ( F 2 F ) Communication : The Next Evolution Step in 5 G Wireless Backhauling

The future 5G cellular networks are expected to support several-fold increase in data traffic and number of devices, and provide a very low latency and gigabit-rate data services. millimeter Wave (mmWave) communication (30 – 300 GHz) is proposed to be an important part of the 5G cellular networks to fulfill these requirements. With most of the high data rate demands originating from indoor User Equipments (UEs), conventional wired backhaul links prove to be a major bottleneck. Hence, mmWave wireless backhaul links are explored at Femto Base Stations (FBSs). In order to derive maximum benefit of mmWave backhaul links, efficient resource (data slots) utilization is necessary. Proper scheduling of mmWave backhaul links will help to achieve the same. In this paper, we propose a novel FBSto-FBS (F2F) communication scheme which not only helps in offloading the data traffic from the Micro Base Station (MiBS) but also can act as a relay link for the other FBSs for routing the backhaul traffic to the MiBS. We also propose a solution to concurrently schedule mmWave wireless backhaul links to increase the resource utilization considering the coexistence of both FBS-to-MiBS (F2M) and F2F links. Our proposed solution consists of two parts – first, it determines which backhaul links can be scheduled concurrently by finding the upper bound for the interfering distance based on the alignment of different lobes of the directional antennas. Second, the transmit power is throttled to match the Quality of Service (QoS) requirements of each link aiming to further control the interference and to increase the number of concurrent transmissions. The benefits of the proposed solution are studied and compared with the Time Division Multiple Access (TDMA) and random scheduling schemes using extensive simulations.
Designing SMART GE 1.0 system as modern space matrix to map the competitive strategy of SME's

SMART GE.1.0 is a matrix of SPACE system designed with four-quadrant framework that indicates whether a company in the positions of aggressive, conservative, defensive, or competitive to determine the most suitable one for a particular organization. SPACE analysis was the instrument used as a systematic assessment to the four main issues that balances internal and external factors determining the theme of the strategy. The external factors are Indutrial advantage and Environment Stability, and the internal factors are Competitive advantage and Financial strength. Combining the ratings on each dimension in SMART GE.1.0 results in a frame of reference that show the position of a company so that it can be a strategic agenda. Financial strength is required to offset the environmental instability. A source of profit is industry attractiveness and competitive advantage. Then, both should have good values, otherwise, it means the business is in trouble. SME's experience difficulties in improving the quality of their businesses in the market internally and externally. The results of SWOT analysis show that external factors influence the most on SME's performance. In this regard, it is necessary to conduct the matching phase using SPACE matrix to determine the conditions of SME's at this time. The analysis results used SMART GE 1.0 system applied to 100 SME's in Semarang Culinary SME's. It provided information that most SME's were in aggressive condition.
Making service robots human-safe

This paper first reviews the literature about the very important but neglected issue of safety in service-robots applications. Most of the few existing approaches are limited because they lack flexibility. We argue that human-tailored safety schemes are greatly needed, and propose two strategies in the line we think human-safe robots should be conceived. A fast method to derive the robot's incremental movements given a workspace force applied to the robot constitutes the basis of the robot behaviors that underlie the proposed strategies. Our simulations show that our strategies are safe, human-friendly and exhibit real-time performance. Finally, we discuss the many ways in which our work can be extended.
Information Retrieval System Using Latent Contextual Relevance

When the relevance feedback, which is one of the most popular information retrieval model, is used in an information retrieval system, a related word is extracted based on the first retrival result. Then these words are added into the original query, and retrieval is performed again using updated query. Generally, Using such query expansion technique, retrieval performance using the query expansion falls in comparison with the performance using the original query. As the cause, there is a few synonyms in the thesaurus and although some synonyms are added to the query, the same documents are retireved as a result. In this paper, to solve the problem over such related words, we propose latent context relevance in consideration of the relevance between query and each index words in the document set.
Effect of Altered Body CO2 Stores on Pulmonary Gas Exchange Dynamics During Incremental Exercise in Humans

The lactate threshold is a widely used and, at times, controversial construct in exercise physiology and pathophysiology. Its non‐invasive estimation during incremental exercise depends upon CO2 output increasing as a function of O2 uptake, i.e. ‘V‐slope’, as a result of bicarbonate buffering during the lactic acidosis. However, we hypothesised that the V‐slope deflection could also occur as a consequence of metabolic CO2 being diverted proportionally more into the CO2 stores in the early phase of exercise. Eight healthy males performed two incremental exercise tests on a cycle ergometer, with and without controlled prior hyperventilation; the hyperventilation caused end‐tidal PCO2 to decline by [sim]10 mmHg, with the clearance of a CO2 volume averaging 2547 ml. This corresponded to an ‘effective’ CO2 capacitance of some 3·12 ml mmHg−1 kg−1. Gas exchange was determined breath‐by‐breath, and blood was sampled from the dorsum of the heated hand. Our results demonstrate that the early dynamics of CO2 wash‐in to the previously depleted body stores can result in a ‘pseudo‐threshold’, i.e. significantly before the onset of the actual lactic acidosis. Precautions should therefore be taken to avoid hyperventilation prior to non‐invasive estimation of the lactate threshold.
Pedometer Development Utilizing an Accelerometer Sensor

This paper develops a pedometer with a three-axis acceleration sensor that can be placed with any angle. The proposed pedometer measures the number of steps while users walk, jog or run. It can be worn on users’ waistband or placed within pocket or backpack. The work address to improve on the general pedometers, which can only be used in a single direction or can only count of steps without the continuous exercise judgment mechanism. Finally, experimental results confirm the superior performance of the proposed pedometer. Keywords—Accelerometer sensor, Angle estimation, Pedometer.
Sandwich mapping of diseases with a small sample in a stratified heterogeneous domain

The error associated with the mapping of a disease is determined based on the sampling triple: the properties of the disease, the way of sampling and the methods used for mapping. The Kriging method projects the best linear unbiased disease map if the disease data have both spatial autocorrelation (SAC) and second-order stationarity. The Kriging method fails if SAC is null or weak. For such a situation, the sandwich interpolation method is applicable if the disease shows stratified heterogeneity in a space. The sandwich mapping comprises three steps: the domain is stratified based on the principle of minimizing variance within strata and maximizing variance between strata; the prevalence value and its variance within a stratum are estimated; and lastly, the quantities of strata are transformed into the reporting units.
Evolution of New Disease Specificity at a Simple Resistance Locus in a Crop–Weed Complex: Reconstitution of the Lr21 Gene in Wheat

The wheat leaf-rust resistance gene Lr21 was first identified in an Iranian accession of goatgrass, Aegilops tauschii Coss. , the D-genome donor of hexaploid bread wheat, and was introgressed into modern wheat cultivars by breeding. To elucidate the origin of the gene, we analyzed sequences of Lr21 and lr21 alleles from 24 wheat cultivars and 25 accessions of Ae. tauschii collected along the Caspian Sea in Iran and Azerbaijan. Three basic nonfunctional lr21 haplotypes, H1, H2, and H3, were identified. Lr21 was found to be a chimera of H1 and H2, which were found only in wheat. We attempted to reconstitute a functional Lr21 allele by crossing the cultivars Fielder (H1) and Wichita (H2). Rust inoculation of 5876 F2 progeny revealed a single resistant plant that proved to carry the H1H2 haplotype, a result attributed to intragenic recombination. These findings reflect how plants balance the penalty and the necessity of a resistance gene and suggest that plants can reuse “dead” alleles to generate new disease-resistance specificity, leading to a “death–recycle” model of plant-resistance gene evolution at simple loci. We suggest that selection pressure in crop–weed complexes contributes to this process.

Pathologic Changes of the Small Intestinal Mucosa of Pigs after Feeding Phaseolus vulgaris Beans

The jejunal mucosa of pigs fed diets containing Phaseolus vulgaris beans was characterized grossly as mucosal atrophy and microscopically as atrophy and blunting of the villus in association with elongation of crypts with cells with increased mitotic activity. These morphologic findings were most severe in the proximal and middle parts of the jejunum. Compared to controls, goblet cells were significantly decreased in the villus but markedly increased in the crypt region. The activity of aminopeptidase and sucrase-isomaltase in the test animals was also significantly lower than in the controls. The findings in this study suggested that feeding Phaseolus vulgaris beans reduced the digestive and absorptive capacity of the mucosa, resulting in weight loss and diarrhea of affected pigs.
An Analysis of Turn-Taking and Backchannels Based on Prosodic and Syntactic Features in Japanese Map Task Dialogs

In this study, we investigate syntactic and prosodic features of the speaker's speech at points where turn-taking and backchannels occur, on the basis of our analysis of Japanese spontaneous dialogs. Specifically, we focus on features such as part of speech, duration, F0 contour pattern, relative height of the peak F0, energy trajectory pattern, and relative height of the peak energy at the final part of speech segments. We examine, first, the relationship between turn-taking/backchannels and each feature of speech segments independently, showing that the features examined in this study are all related to turn-taking or backchannels and that the way they correlate is fairly consistent with previous studies. Next, we explore the inter-relationship among the features with respect to turn-taking and backchannels. We show that in both turn-taking and backchannels, (I) some instances of syntactic features make extremely strong contributions, and (2) in general, syntax has a stronger contribution than any individual prosodic feature, although the whole prosody contributes as strongly as, or even more strongly than, syntax. We also discuss some implications of our results, comparing them with previous models that have mentioned roles of syntax and prosody in turn-taking and backchannels.
Hybrid spreading of the Internet worm Conficker

Conficker is a computer worm which erupted on the Internet in 2008. It is unique in combining three different spreading strategies: local probing, neighbourhood probing, and global probing. We propose a mathematical model to infer the worm’s parameters from network measurement data. We reveal that it is the mixture of spreading mechanisms that makes Conficker one of the most infectious worms, as it is extremely efficient at exploiting any weakness present on the Internet. We show that potential measures to limit the spread of the worm work in theory but are difficult to implement in practice. Our work calls for new and more effective strategies to defend against Conficker-like worms.
Prospective Clinical Pilot Trial in a Single Cohort Group of rhPDGF in Foot Arthrodeses

Background: Augment™ Bone Graft, a fully synthetic bone graft material composed of recombinant human PDGF and a calcium phosphate matrix (rhPDGF/TCP), has been considered as a possible alternative to autogenous bone graft. Before proceeding with randomized control studies comparing rhPDGF/TCP to autograft bone, a human trial to assess efficacy and safety was required. Materials and Methods: The current study was a prospective, open-label, multi-center trial designed to evaluate rhPDGF in a calcium phosphate matrix (Augment™ Bone Graft). Sixty patients requiring hindfoot or midfoot fusion were prospectively followed for 36 weeks. All patients received 0.9 to 2.7 mg of rhPDGF at the fusion sites and returned for clinical and radiographic review at Day 7 to 14 and Weeks 6, 9, 12, 16, 24, and 36. Computerized tomography (CT) scans of the fusion site were obtained at the 6- and 12-week postoperative appointment, with an additional CT scan at 16 weeks if required. Results: No patients suffered a serious adverse event caused by rhPDGF. CT scan evaluation at 12- to 16-week time periods revealed moderate or complete osseous bridging of 75% (44/59) at 36 weeks. Conclusion: These results indicate that rhPDGF is a safe product and provides clinical/radiographic outcomes that justify the pursuit of randomized controlled studies comparing rhPDGF/TCP to autograft. Level of Evidence: IV, Case Series
