A multi-objective particle swarm optimisation for filter-based feature selection in classification problems

Feature selection has the two main objectives of minimising the classification error rate and the number of features. Based on binary particle swarm optimisation (BPSO), we develop two novel multi-objective feature selection frameworks for classification, which are multi-objective binary PSO using the idea of non-dominated sorting (NSBPSO) and multi-objective binary PSO using the ideas of crowding, mutation and dominance (CMDBPSO). Four multi-objective feature selection methods are then developed by applying mutual information and entropy as two different filter evaluation criteria in each of the proposed frameworks. The proposed algorithms are examined and compared with a single objective method on eight benchmark data sets. Experimental results show that the proposed multi-objective algorithms can evolve a set of solutions that use a smaller number of features and achieve better classification performance than using all features. In most cases, NSBPSO achieves better results than the single objective algorithm and CMDBPSO outperforms all other methods mentioned above. This work represents the first study on multi-objective BPSO for filter-based feature selection.
A novel 12-teeth/10-poles PM machine with flux barriers in stator yoke

Using magnetic flux barriers in the stator yoke of electric machines with fractional slots, tooth-concentrated winding it is possible to reduce or even to cancel some space harmonics of low order in air-gap flux density resulting in lower rotor losses induced by the armature reaction field. This technique is applied to a PM machine with 12-teeth/10-poles winding during designing of an electric machine for automotive application. According to the new technique a prototype machine is buildet and some measurement results are given. The first measurement results for the induced voltage show a good agreement with the simulation data.
Test-Retest Reliability of Physiological and Performance Responses to 120 Minutes of Simulated Soccer Match Play

Abstract Harper, LD, Hunter, R, Parker, P, Goodall, S, Thomas, K, Howatson, G, West, DJ, Stevenson, E, and Russell, M. Test-retest reliability of physiological and performance responses to 120 minutes of simulated soccer match play. J Strength Cond Res 30(11): 3178–3186, 2016—This study investigated the test-retest reliability of physiological and performance responses to 120 minutes (90 minutes plus 30 minutes extra-time [ET]) of the soccer match simulation (SMS). Ten university-standard soccer players completed the SMS on 2 occasions under standardized conditions. Capillary and venous blood was taken pre-exercise, at half-time, and at 90 and 120 minutes, with further capillary samples taken every 15 minutes throughout the exercise. Core temperature (T core ), physical (20- and 15-m sprint speeds and countermovement jump height), and technical (soccer dribbling) performance was also assessed during each trial. All variables except blood lactate demonstrated no systematic bias between trials (p > 0.05). During the last 15 minutes of ET, test-rest reliability (coefficient of variation %, Pearson's r, respectively) was moderate to strong for 20-m sprint speed (3.5%, 0.71), countermovement jump height (4.9%, 0.90), dribble speed (2.8%, 0.90), and blood glucose (7.1%, 0.93), and very strong for T core (1.2%, 0.99). Moderate reliability was demonstrated for 15-m sprint speed (4.6%, 0.36), dribble precision (11.5%, 0.30), plasma insulin (10.3%, 0.96), creatine kinase ([CK] 28.1%, 0.38), interleukin-6 (24%, 0.99), nonesterified fatty acids ([NEFA] 13.2%, 0.73), glycerol (12.5%, 0.86), and blood lactate (18.6%, 0.79). In the last 15 minutes of ET, concentrations of blood glucose and lactate and sprint and jump performances were reduced, whereas T core , NEFA, glycerol, and CK concentrations were elevated (p ⩽ 0.05). The SMS is a reliable protocol for measuring responses across the full 120 minutes of soccer-specific exercise. Deleterious effects on performance and physiological responses occur during ET.
Elliptic Curve Cryptography based Security Framework for Internet of Things and Cloud Computing

Internet of Things (IoT) and Cloud Computing paradigm is a next wave in the era of computing and it has been identified as one of the emerging technologies in the field of Computer Science and Information Technology. It has been understood from the review reports that integration of IoT and Cloud Computing is in its infantile phase and it has not been extended to all application domains due to its inadequate security architecture. Hence, in this paper a novel Elliptic Curve Cryptography based security framework for Internet of Things and Cloud Computing is proposed. This is a secured and adoptable one for the public to access diversified smart applications and services distributed in the cloud, anywhere, anytime, any device and any network irrespective of the underlying technologies in a smart environment. The cloud services are integrated and connected through a novel IP/MPLS (Internet Protocol/ Multiprotocol Label Switching) core. Elliptic Curve Cryptography (ECC) is used to ensure complete protection against the security risks such as confidentiality, integrity, privacy and authentication. This model eliminates ambiguity and ensures security with enhanced performance and realizes the vision of one intelligent smart card for any applications and transactions. The security strengths of various public key cryptosystems are analysed and ensured ECC is one of the best cryptosystems for internet of things and cloud.

Presence of a Novel DNA Methylation Enzyme in Methicillin-Resistant Staphylococcus aureus Isolates Associated with Pig Farming Leads to Uninterpretable Results in Standard Pulsed-Field Gel Electrophoresis Analysis

ABSTRACT Genomic DNA from methicillin-resistant Staphylococcus aureus isolates recovered from pigs and their caretakers proved resistant to SmaI digestion, leading to uninterpretable results in standard pulsed-field gel electrophoresis. This is the result of a yet unknown restriction/methylation system in the genus Staphylococcus with the recognition sequence CCNGG.
Experimental verification of coplanar-to-substrate-integrated-waveguide interconnect on low-permittivity substrate

An interconnect between coplanar waveguide (CPW) and substrate integrated waveguide (SIW) is designed and experimentally verified. Common to regular SIW circuits is a low-permittivity substrate, whereas design formulas CPW usually assume a high permittivity. Therefore, commercially available field solvers are used in a parametric study to optimize the interconnect over a wide bandwidth between 18 GHz and 28 GHz. Cross-sectional field plots demonstrate its basic operation. The individual interconnect achieves return and insertion losses better than 20 dB and 0.5 dB, respectively, over the entire frequency range. The respective values for a measured back-to-back transition are 17 dB and 1.45 dB which are in good agreement with simulations.
Quorum sensing inhibition in Pseudomonas aeruginosa biofilms: new insights through network mining

Abstract Quorum sensing plays a pivotal role in Pseudomonas aeruginosa’s virulence. This paper reviews experimental results on antimicrobial strategies based on quorum sensing inhibition and discusses current targets in the regulatory network that determines P. aeruginosa biofilm formation and virulence. A bioinformatics framework combining literature mining with information from biomedical ontologies and curated databases was used to create a knowledge network of potential anti-quorum sensing agents for P. aeruginosa. A total of 110 scientific articles, corresponding to 1,004 annotations, were so far included in the network and are analysed in this work. Information on the most studied agents, QS targets and methods is detailed. This knowledge network offers a unique view of existing strategies for quorum sensing inhibition and their main regulatory targets and may be used to readily access otherwise scattered information and to help generate new testable hypotheses. This knowledge network is publicly available at http://pcquorum.org/.
Preserved Emotional Modulation of Motor Response Time Despite Psychomotor Slowing in Young-Old Adults

ABSTRACT Whereas aging affects cognitive and psychomotor processes negatively, the impact of aging on emotional processing is less clear. Using an “old–new” binary decision task, we ascertained the modulation of response latencies after presentation of neutral and emotional pictures in “young” (M = 27.1 years) and “young-old” adults with a mean age below 60 (M = 57.7 years). Stimuli varied on valence (pleasant, neutral, and unpleasant) and arousal (high and low) dimensions. Young-old adults had significantly longer reaction times. However, young and young-old adults showed the exact same pattern of response time modulation by emotional stimuli: Response latencies were longer for high-arousal than for low-arousal pictures and longer for negative than for positive or neutral stimuli. This result suggests that the specific effects of implicitly processed emotional valence and arousal information on behavioral response time are preserved in young-old adults despite significant age-related psychomotor decline.
On the Austral-Antarctic stenothoids Proboloides, Metopoides, Torometopa and Scaphodactylus (Crustacea Amphipoda) Part 2: the genus Proboloides, with description of two new genera and the transfer of two nominal species to Metopoides

Abstract This is the second part of a revision of the most plesiomorphic genera in the amphipod family Stenothoidae sensu lato (see Krapp-Schickel and Koenemann 2006 for an overview and Krapp-Schickel 2008 for the first part). 41 species not belonging to Metopoides were plotted in a matrix using the same 61 characters as in the first part. The resulting group of Proboloides species (most probably not existing in the Austral-Antarctic region) is discussed, a key for the members given and two new genera erected. Some species described as Proboloides are redescribed and 2 species transferred to Metopoides. A key for all actual members of. The remaining species, i.e. those actually being in the genera Torometopa and Scaphodactylus, will be dealt with in the final part of this series, together with a key to all of them.
Non-coherent distributed space-time processing for multiuser cooperative transmissions

User cooperation can provide spatial transmit diversity gains, enhance coverage and potentially increase capacity. Existing works have focused on two-user cooperative systems with perfect channel state information at the receivers. In this paper, we develop several distributed space-time processing schemes for general TV-user cooperative systems, which do not require channel state information at either relays or destination. We prove that full spatial diversity gain can be achieved in such systems. Simulations demonstrate that these cooperative schemes achieve significant performance gain
Natural infection of human adenovirus 36 in rhesus monkeys is associated with a reduction in fasting glucose 恒河猴自然感染人36型腺病毒与空腹血糖下降有关

In humans, natural Ad36 infection is crosssectionally and temporally associated with adiposity and better glycemic control. 1–3 In vitro studies indicate that the early gene 4, open reading frame 1 (E4orf1) gene of Ad36 is necessary and sufficient to improve cellular glucose disposal. 4,5 Consequentially, E4orf1 protein offers an excellent template to develop antidiabetic drugs. 4 Considering the human relevance of a rhesus monkey model for preclinical drug development, we determined the associations of natural Ad36 infection with changes in glycemic control in rhesus monkeys. For this study, serum samples were obtained from 20 male rhesus monkeys (Macaca mulatta; 7–13 years of age) enrolled in an ongoing study described earlier. 6
Role of Depression in Outcomes of Low-Energy Distal Radius Fractures in Patients Older Than 55 Years

Objectives: This study examines depression and outcomes in patients older than 55 years with distal radius fracture. Design: Prospective data collection included patient characteristics, treatment, general and limb symptoms and disability, and complications at baseline, 3 months, and 1 year. Bivariate analysis and multivariable linear regression were used to assess relationships between depression and outcome measures, specifically the Short Form-36 (SF-36), Disability of the Arm, Shoulder, and Hand (DASH) scores, and the Centre of Epidemiologic Studies Depression (CES-D) scale. Setting: The study was conducted in a level-1 trauma center. Participants: All patients older than 55 years with isolated distal radius fracture were recruited (2007–2011). Intervention: Patients were treated operatively or nonoperatively. Main Outcome Measures: The SF-36 and DASH scores measured general and upper extremity status. Depression was measured using CES-D scale. All complications were recorded. Results: Of 228 patients, 25% were depressed at baseline, 32% at 3 months, and 26% after 1 year. Thirty-two patients (14%) had complications. There was no relationship between depression at baseline and complications; however, there was a statistically significant relationship at 3 months (P = 0.021). There was a statistically significant association between baseline depression and the worse 1-year SF-36. Patients with baseline depression had poorer 1-year DASH scores (20 ± 2.3) than nondepressed patients (11 ± 1.3) (P = 0.0031), and less improvement in DASH scores over the first year (P = 0.023). Multivariable linear regression demonstrated that baseline depression is the strongest predictor of poorer 1-year DASH scores (3.7, P = 0.0078) and change in DASH scores over the first year (2.9, P = 0.026). Conclusions: Baseline depression predicts worse function and disability outcomes 1 year from injury. Depression (CES-D ≥16) is the strongest predictor of worse 1-year DASH scores and SF-36 outcome measures, after controlling for other potential predictors. Level of Evidence: Prognostic Level I. See Instructions for Authors for a complete description of levels of evidence.
Validation of a rubric to assess innovation competence

This paper addresses the development and validation of rubrics, materials and situations for the assessment of innovation competence.

State-of-the-art time link calibration with a mobile TWSTFT station

Two-Way Satellite Time and Frequency Transfer (TWSTFT) using geostationary telecommunication satellites has become an important technique for comparing remote timescales. There is a need for periodic calibration of the signal delays along the links which are part of the network for the realization of the International Atomic Time (TAI). In order to minimize the efforts of such TWSTFT calibration campaigns, TimeTech GmbH has assembled a mobile station on a trailer. The trailer contains the usual TWSTFT equipment, including the two-way modem, the up/down converters, filters, and amplifiers, as well as monitoring systems, air conditioner, and weather sensors. The steerable antenna is mounted on top of the trailer. The 1 PPS and 10 MHz signals required as input to the TWSTFT equipment are transferred from inside the timing laboratory by an optical link and two reference generators in a master-slave configuration.
Ultrasonography for diagnosis of orbital tumors.

The diagnosis of intra-orbital tumors is frequently difficult, and sometimes, in spite of all investigative attempts, the cause of unilateral ocular proptosis is not determined. Also, in cases where the presence of a tumor is strongly suspected, it is occasionally difficult to learn the orbital location of the neoplasm for planning of surgical approach. Ultrasonography of the orbit has been useful for these purposes, and reaching the decision to perform surgical removal is thus simplified. Ultrasonography of the orbit is easily performed and is harmless when done properly.
Parameter estimation of spontaneous emission by performing projective measurements

The identification problem of open quantum systems was explored in this paper. We proposed an algorithm to testify the feasibility of a framework for dynamical generator identification through numerical simulations on the specific quantum process - the hydrogen atomic spontaneous emission induced by the two-level electronic transition from a high energy state to a low energy state. We demonstrated how to estimate spontaneous emission parameters by repeated projective measurements through the identification algorithm, and discussed the sampling frequency, the required least quantity of initial states and projective measurements and this algorithm's the scope and performance.
Low complexity energy optimization algorithm for massive MIMO systems

We consider the problem of nearly optimal energy efficiency in massive (Multiinput Multi-output) MIMO systems. Considering the correlated channel in practice, we derive the ergodic expression with zero-forcing precoding and analyze the simplified antennas selection method. Aiming at optimizing the energy efficiency, the closed form expressions of the nearly optimal number of transmit antennas and transmit power are given under the circuit consumption model. The joint solution of the number of transmit antennas and transmit power was replaced to only solve transmit power. Based on the expression only related with transmit power, we give an energy efficiency optimization algorithm. The simulation results show that the proposed algorithm can achieve nearly optimal energy efficiency with fast convergence speed.
Performance of iterative turbo coding with nonlinearly distorted OFDM signal

In this paper, the performance of iterative turbo coding with nonlinearly distorted orthogonal frequency division multiplexing (OFDM) signal is analyzed. System level implementation in Simulink is performed and bit error rate (BER) performance is analyzed. Initially, we have implemented both, the series turbo coder and iterative turbo coder, compared the performance and then using better performed iterative coder, model is implemented in Simulink. In the model, we introduced highly nonlinear distortion signal using solid state power amplifier (SSPA). It is observed that nonlinear distortion results in very high BER. However, BER performance is significantly improved by the use of iterative turbo coder. It is also seen that 6 iterations is found to be optimum. Higher or smaller iteration results in reduced performance.
Stem Cell Based Therapy for Muscular Dystrophies: Cell Types and Environmental Factors Influencing Their Efficacy

Muscular dystrophies are inherited disorders in which muscle fibers are unusually susceptible to damage, leading to progressive loss of muscle structure and function. Some types of muscular dystrophy affect heart muscles, other involuntary muscles and other organs. The most common form of muscular dystrophy, Duchenne Muscular Dystrophy (DMD), is due to genetic deficiency of the protein dystrophin (Monaco et al., 1985). This protein is one of several partners that interact to link intracellular cytoskeleton to extracellular matrix (ECM) hence consolidating the scaffold necessary for maintaining structural integrity of skeletal muscle fibers. Dystrophin deficiency destabilizes muscle fibers, which become less resistant to contractions leading to muscle fiber necrosis and subsequent regeneration.
Intelligent sensor network for obstacle avoidance strategy

An obstacle avoidance system was developed for a custom-made autonomous navigational robotic vehicle (ANROV), based on an intelligent sensor network and fuzzy logic control. Unlike conventional crisp control systems, this system is based on soft computing, such that the system mimics human decision making processes and can better recognize obstacles and decide the best course of action. The fuzzy logic control system was developed in MATLAB, the GUI was designed in LabView, and the hardware realization was installed in ANROV for evaluation and development
Wettability of Amorphous Diamond-Like Carbons Deposited on Si and PMMA in Pulse-Modulated Plasmas

Pulse-modulated direct-current methane plasmas are used to deposit amorphous diamond-like carbon films on Si and dentistry-use polymethyl methacrylate (PMMA) substrates as a function of the negative pulse voltage applied to the substrate (Vmax). The films on PMMA show a transition from diamond-like to more graphitic carbon in the Raman spectra with increasing Vmax, dissimilar to those on Si. This is attributed to easy deformation of PMMA, leading to the low compressive stress of the films (1 to 2 GPa). The contact angle of water for the films on both Si and PMMA is large, ranging from 79° to 94° almost independent of Vmax, confirming that the films are hydrophobic despite the difference in carbon bonding state. The large dispersion component (41-43 mJ/m2) of the surface free energy of the films measured from the contact angle of water and 1-bromonaphthalene indicates the high mass density of the films. The small polar component (0.2-3.5 mJ/m2) is attributed to hydrogen saturation of the surface sites forming nonpolar C-H bonds and, thus, responsible for the hydrophobic behavior.
RESPIRATORY SYSTEM MORPHOLOGY AND THE PHYLOGENY OF HAPLOGYNE SPIDERS (ARANEAE, ARANEOMORPHAE)

Abstract The morphology of the respiratory system of basal araneomorph spiders, the Haplogynae and of Entelegynae with female haplogyne genitalia, is reviewed. The homology of cuticular respiratory structures is discussed in light of evidence from abdominal muscles and ontogeny. Ten morphological characters (13 transformations) were coded, mainly from the posterior pulmonary (or tracheal) segment, and other 7 non-respiratory characters here added. The new data were combined with those of a previously published analysis, resulting in a data matrix of 82 characters scored for 44 terminals. The evolution of the tracheal system is traced through the phylogeny of basal spiders and the Haplogynae, and new synapomorphies are provided. Elongate 3rd abdominal entapophyses are a synapomorphy of Araneomorphae. True median tracheae are a synapomorphy of Entelegynae (convergently with Austrochilinae), as is the extreme posterior displacement and narrowing of the tracheal spiracle. Tetrablemmidae, Pholcidae, Diguetidae and Plectreuridae are united by the absence of tracheae; and these taxa are united with Scytodidae, Sicariidae and Drymusidae by the fusion of 3rd entapophyses.
