Thermal Emission from H II Galaxies: Discovering the Youngest Systems

We studied the properties of very young massive star-forming regions in H II galaxies, with the aim of detecting signs of evolution where the first supernovae (SNe) start to appear. Our sample consists of 31 H II galaxies, characterized by strong hydrogen emission lines, for which low-resolution VLA 3.5 and 6 cm observations were obtained. We found that the radio spectral energy distribution (SED) has a range of behaviors: galaxies where the SED is characterized by a synchrotron-type slope; galaxies with a thermal slope; and galaxies with possible free-free absorption at long wavelengths. The latter represent a signature of heavily embedded massive star clusters. Comparing the different star formation rates (SFRs), we find that SFR(Hα) is on average significantly higher than SFR(1.4 GHz). We confirm this tendency by comparing the ratio of the observed flux at 20 cm to the expected one, calculated based on the SFR Hα, both for the galaxies in our sample and for normal ones. We show that this ratio is a factor of 2 smaller in our galaxies than in normal ones, indicating that they do not follow the FIR/radio correlation (q-parameter). These results suggest that the emission of these galaxies is dominated by a recent star-forming event in which the first SNe started to explode, consistent with the radio emission being dominated by free-free continuum. We propose an evolutionary scenario to explain the observed trends and conclude that the systematic lack of synchrotron emission in those systems with the largest equivalent width of Hβ can only be explained if those are young starbursts of less than 3.5 Myr of age, i.e., before the first Type II SNe start to explode.
Cloning and analysis of the Glwc‐1 and Glwc‐2 genes encoding putative blue light photoreceptor from Ganoderma lucidum

Blue light plays an important role during the growth of Ganoderma lucidum, one of the best‐known medicinal macrofungi in China. In the present study, we cloned Glwc‐1 and Glwc‐2, the homologue of the blue light photoreceptors Ncwc‐1 and Ncwc‐2 of Neurospora crassa, from G. lucidum. The deduced amino acid sequence of Glwc‐1 contained the similar function domains as NcWC‐1 including LOV, PAS B, PAS C, and PAC domains. The deduced amino acid sequence of Glwc‐2 contained PAS domain and GATA‐type zinc finger (Znf) domain as well as NcWC‐2. Phylogenetic analysis based on fungal WC‐1 and WC‐2 supported GlWC‐1 and GlWC‐2 were blue light receptors. The expression of Glwc‐1 and Glwc‐2 indicated that they might play an important role during the primordium differentiation process of G. lucidum, and the external blue light stimulation increased the expression of Glwc‐1 and Glwc‐2.
Temperature-insensitive micromachined AlGaAs-GaAs vertical cavity filter

We have demonstrated a temperature-insensitive micromachined vertical cavity filter with an AlGaAs-GaAs distributed Bragg reflector (DBR), which can be thermally tuned by differential thermal expansion. The achieved temperature dependence was as small as +0.01 nm/K, which is one-tenth of that of conventional semiconductor based optical filters.
Tranexamic acid and trauma

TO THE EDITOR: Gruen and colleagues1 have not accurately represented the current safety data on the risk of vascular occlusive events (VOE) with tranexamic acid (TxA), including deep vein thrombosis (DVT) and pulmonary embolism (PE). A systematic review of data for 10 488 surgical patients showed lower mortality with TxA and no difference in DVT (risk ratio [RR], 0.86; 95% CI, 0.53–1.39; P = 0.54) or PE (RR, 0.61; 95% CI, 0.25–1.47; P = 0.27). 2 The CRASH-2 (Clinical Randomisation of an Antifibrinolytic in Significant Haemorrhage 2)3 trial involving 20 211 patients showed there was a trend to fewer VOE in the tranexamic acid group compared with placebo (168/10 060 [1.7%] v 201/10 067 [2.0%]; P = 0.084). Gruen et al implied that the low rate of PE (0.7%) and DVT (0.4%) in this study renders these findings suspect. Low detection of DVT and PE applied equally to both groups and only affects study power — which is not an issue in this large study. Gruen and colleagues stated that “in contrast” the observational MATTERs (Military Application of Tranexamic Acid in Trauma Emergency Resuscitation)4 trial showed PE and DVT rates that were, respectively, nine and 12 times the rates for the control group. They neglected to mention that the rates in the control group were 2/603 (0.3%) and 1/603 (0.2%) — lower than the rates in the less severely injured CRASH 2 patients. The MATTERs study was unblinded, so the difference could easily have been due to more investigations in the TxA group. Finally, the MATTERs study reported that the inhospital mortality in the TxA group was 17.4% compared with 23.9% in the group not given TxA (P = 0.03). Unlike nonfatal DVT and PE, death is not a condition that requires investigations to diagnose. James Jarman Anaesthetist
BGOA-TVG: Binary Grasshopper Optimization Algorithm with Time-Varying Gaussian Transfer Functions for Feature Selection

Feature selection aims to select crucial features to improve classification accuracy in machine learning and data mining. In this paper, a new binary grasshopper optimization algorithm using time-varying Gaussian transfer functions (BGOA-TVG) is proposed for feature selection. Compared with the traditional S-shaped and V-shaped transfer functions, the proposed Gaussian time-varying transfer functions have the characteristics of a fast convergence speed and a strong global search capability to convert a continuous search space to a binary one. The BGOA-TVG is tested and compared to S-shaped and V-shaped binary grasshopper optimization algorithms and five state-of-the-art swarm intelligence algorithms for feature selection. The experimental results show that the BGOA-TVG has better performance in UCI, DEAP, and EPILEPSY datasets for feature selection.
Trust Issues that Create Threats for Cyber Attacks in Cloud Computing

The research contribution in this paper is twofold. First, an investigative survey on cloud computing is conducted with the main focus on gaps that is slowing down cloud adoption as well as reviewing the threat remediation challenges. Next, some thoughts are constructed on novel approaches to address some of the widely discussed attack types using machine learning techniques. Such thoughts captured through a series of experiments are expected to give researchers, cloud providers and their customers' additional insight and tools to proactively protect themselves from known or perhaps even unknown security issues that follow the same patterns.
MEGSOR Iterative Scheme for the Solution of 2D Elliptic PDE's

Recently, the findings on the MEG iterative scheme has demonstrated to accelerate the convergence rate in solving any system of linear equations generated by using approximation equations of boundary value problems. Based on the same scheme, the aim of this paper is to investigate the capability of a family of four-point block iterative methods with a weighted parameter, I‰ such as the 4 Point-EGSOR, 4 Point-EDGSOR, and 4 Point-MEGSOR in solving two-dimensional elliptic partial differential equations by using the second-order finite difference approximation. In fact, the formulation and implementation of three four-point block iterative methods are also presented. Finally, the experimental results show that the Four Point MEGSOR iterative scheme is superior as compared with the existing four point block schemes.
Electrical Double Layer on Silver Iodide and Overcharging in the Presence of Hydrolyzable Cations

Previous studies on the surface charge and electrokinetic charge on silver iodide as a function of the pAg in the presence of some monovalent and trivalent cations as the counterions were extended to include the influence of pH. The main reason for this study was to investigate the possible propensity of overcharging by adsorption of hydrolyzed counterions. It was found that for K+ as the counterion the double layer properties could be well represented in terms of a simple Gouy-Stern model, without accounting for hydrolysis. However, with Al3+ or La3+ as the counterions, adsorption of hydrolyzed species takes place when the pH is high enough, leading to electrokinetic charge reversal.
Common Visual Pattern Detection by Mixture Particle Filtering

We present a novel approach to detect common visual patterns between image pairs. We use a particle filtering approach as a detector of possibly multiple similar visual patterns rather than as a visual tracker. Our method doesn’t require a learning phase in advance but leverages only the information from given two images. A detector is a set of bounding boxes (or particles) which are located initially at random on each image. A set of bounding boxes on an image is updated based on both their current states and the observation of counterparts on another image through a particle filtering framework. A bounding box will include some feature points of the image and the similarity between two boxes can be calculated by the number of corresponding points. This similarity defines a likelihood model. The state of two sample sets should be updated to move toward the locations of common patterns in turn. To handle multiple instances, we adopt an algorithm of the mixture particle filter. In the experiments, we demonstrate the validity of our method on common visual pattern detection.
The Contingent Effects of Training, Technical Complexity, and Task Interdependence on Successful Information Systems Implementation

Research has investigated the main effect of training on information systems implementation success. However, empirical support for this model is inconsistent. We propose a contingent model in which the effect of training on IS implementation success is a function of technical complexity and task interdependence. A meta-analysis of the literature finds strong support for the model, explaining the inconsistent findings reported in the literature. Implications for theory and practice are discussed.
A New Semi-blind Channel Estimation for ZP-OFDM Systems

In this paper, a new subspace-based adaptive semi-blind channel estimation method is proposed for zero padding OFDM systems. The algorithm is fully adaptive in the sense that both the subspace information and the optimization . Not only does this algorithm reduce computation complexity, but improves the convergence rate in channel estimation. Simulations demonstrate the effectiveness of the proposed algorithms.
Melatonin and its analogs in insomnia and depression

Abstract: Benzodiazepine sedative‐hypnotic drugs are widely used for the treatment of insomnia. Nevertheless, their adverse effects, such as next‐day hangover, dependence and impairment of memory, make them unsuitable for long‐term treatment. Melatonin has been used for improving sleep in patients with insomnia mainly because it does not cause hangover or show any addictive potential. However, there is a lack of consistency on its therapeutic value (partly because of its short half‐life and the small quantities of melatonin employed). Thus, attention has been focused either on the development of more potent melatonin analogs with prolonged effects or on the design of slow release melatonin preparations. The MT1 and MT2 melatonergic receptor ramelteon was effective in increasing total sleep time and sleep efficiency, as well as in reducing sleep latency, in insomnia patients. The melatonergic antidepressant agomelatine, displaying potent MT1 and MT2 melatonergic agonism and relatively weak serotonin 5HT2C receptor antagonism, was found effective in the treatment of depressed patients. However, long‐term safety studies are lacking for both melatonin agonists, particularly considering the pharmacological activity of their metabolites. In view of the higher binding affinities, longest half‐life and relative higher potencies of the different melatonin agonists, studies using 2 or 3 mg/day of melatonin are probably unsuitable to give appropriate comparison of the effects of the natural compound. Hence, clinical trials employing melatonin doses in the range of 50–100 mg/day are warranted before the relative merits of the melatonin analogs versus melatonin can be settled.
Performance Analysis of Twister based MapReduce Applications on Virtualization System in FutureGrid *

This paper presents the result of performance evaluation of Twister based MapReduce applications to facilitate a virtualized cluster system running in the FutureGrid. For this work, we set up a virtualized cluster system made of a set of VM instances. In this experiment we observe that the overall performance of a data intensive application is strongly affected by the configuration of the VMs and load balancing is essential to handling large files in the case of having limited computing resources in the FutureGrid. The result of this experiment can be used for selecting a set of VM instances in proportion to 1) how much data are processed 2) what type of application runs in the FutureGrid. It can be used to identify the bottleneck of the MapReduce application running on the virtualized cluster system with various VM instances.
On formulas of one variable in intuitionistic propositional calculus

McKinsey and Tarski [3] described Gödel's proof that the number of Brouwerian-algebraic functions is infinite. They gave an example of a sequence of infinitely many distinct Brouwerian-algebraic functions of one argument, which means that there are infinitely many non-equivalent formulas of one variable in the intuitionistic propositional calculus LJ of Gentzen [1]. However they did not completely characterize such formulas. In § 1 of this note, we define a sequence of basic formulas P∞(X), P0(X), P1(X), … and prove the following theorems.
A robust watermarking scheme against contrasts and scaling for PocktNeuro Project

paper presents a robust watermarking scheme of medical information security and terminal mobile phone adaptation for PocketNeuro project. The later term refers to a project created for the service of neurological diseases. It consists of transmitting information about patients « Desk of Patients » to a doctor's mobile phone when he is visiting or examining his patient. Our scheme provides image robustness for both image Gray-level transformation and scaling to adapt them to the doctor's mobile phone. Experiments carried out on a database of 20- 256× 256 pixel- sized medical images show that our watermarking scheme is robust to both scaling and Gray-level transformations. For the purpose of increasing the image watermarking robustness against attacks of an image transmission and to perform a large number of bits to hide into images, we encode with turbo code image-embedded information. Results demonstrate that fidelity can also be improved by this image watermarking scheme.
Automatized generation of alphabets of symbols

In this paper, we discuss the generation of symbols (and alphabets) based on specific user requirements (medium, priorities, type of information that needs to be conveyed). A framework for the generation of alphabets is proposed, and its use for the generation of a shorthand writing system is explored. We discuss the possible use of machine learning and genetic algorithms to gather inputs for generation of such alphabets and for optimization of already generated ones. The alphabets generated using such methods may be used in very different fields, from the creation of synthetic languages and constructed scripts to the creation of sensible commands for multimodal interaction through Human-Computer Interfaces, such as mouse gestures, touchpads, body gestures, eye-tracking cameras, and brain-computing Interfaces, especially in applications for elderly care and people with disabilities.
Structure, Transport, and Seasonality of the Atlantic Water Boundary Current North of Svalbard: Results From a Yearlong Mooring Array

The characteristics and seasonality of the Svalbard branch of the Atlantic Water (AW) boundary current in the Eurasian Basin are investigated using data from a six‐mooring array deployed near 30°E between September 2012 and September 2013. The instrument coverage extended to 1,200‐m depth and approximately 50 km offshore of the shelf break, which laterally bracketed the flow. Averaged over the year, the transport of the current over this depth range was 3.96 ± 0.32 Sv (1 Sv = 10 m/s). The transport within the AW layer was 2.08 ± 0.24 Sv. The current was typically subsurface intensified, and its dominant variability was associated with pulsing rather than meandering. From late summer to early winter the AW was warmest and saltiest, and its eastward transport was strongest (2.44 ± 0.12 Sv), while from midspring to midsummer the AW was coldest and freshest and its transport was weakest (1.10 ± 0.06 Sv). Deep mixed layers developed through the winter, extending to 400‐ to 500‐m depth in early spring until the pack ice encroached the area from the north shutting off the air‐sea buoyancy forcing. This vertical mixing modified a significant portion of the AW layer, suggesting that, as the ice cover continues to decrease in the southern Eurasian Basin, the AW will be more extensively transformed via local ventilation. Plain Language Summary The Svalbard branch of the Atlantic Water (AW) flows eastward north of Svalbard carrying warm and salty waters along the slope of the western Eurasian Basin. Here we explore the characteristics and seasonality of the boundary current using data from a six‐mooring array deployed at 81.7°N, 30.6°E between September 2012 and September 2013. On average the current carries 3.96 ± 0.32 Sv (1 Sv = 10 m/s) of which 2.08 ± 0.24 Sv is of AW. From late summer to early winter the AW was warmest and saltiest, and its eastward transport strongest, while from midspring to midsummer the AW was coldest and freshest and its transport weakest. In this region, the layer of AW is modified via convective overturning in winter.
A quantum is a complex structure on classical phase space

Duality transformations within the quantum mechanics of a finite number of degrees of freedom can be regarded as the dependence of the notion of a quantum, i.e., an elementary excitation of the vacuum, on the observer on classical phase space. Under an observer we understand, as in general relativity, a local coordinate chart. While classical mechanics can be formulated using a symplectic structure on classical phase space, quantum mechanics requires a complex-differentiable structure on that same space. Complex-differentiable structures on a given real manifold are often not unique. This article is devoted to analysing the dependence of the notion of a quantum on the complex-differentiable structure chosen on classical phase space. For that purpose we consider Kahler phase spaces, endowed with a dynamics whose Hamiltonian equals the local Kahler potential.
Extraction of complex wavelet features for iris recognition

This paper presents a new feature extraction method for iris recognition. Since two dimensional complex wavelet transform (2D-CWT) does not only keep wavelet transformpsilas properties of multiresolution decomposition analysis and perfect reconstruction, but also adds its new merits: approximate shift invariance, good directional selectivity for 2-D image, and limited redundancy, which are useful for iris feature extraction. So, a set of high frequency 2D-CWT coefficients are selected as features for iris recognition. The phase information of the coefficients is used for feature encoding and Hamming distance is adopted for classification. Experimental results show that the proposed algorithm can get good recognition rate.
Diagnosis of Alzheimer's disease: Towards accuracy and accessibility

Alzheimer’s disease (AD) is a serious dementia afflicting aging population and is characterized by cognitive decline, amyloid-β plaques, and neurofibrillary tangles. AD substantially impairs the life quality of the victims and poses a heavy burden on the society at large. The number of people with dementia due to AD, prodromal AD, and preclinical AD is estimated to stand at roughly 3.2, 69, and 315 million worldwide, respectively. Current clinical diagnosis is based on clinical symptoms, and clinical research demonstrated that positron emission tomography (PET) and cerebrospinal fluid (CSF) biomarkers had excellent diagnostic performance. However, the application of CSF biomarker tests and PET are restricted by the invasiveness and high cost. The presence of clinical symptoms means that AD pathology has been progressing for many years, and only a few drugs have been approved for the traetemnt of AD. Therefore, early diagnosis is extremely important for controlling the outcomes caused by AD. In this review, we provided an overview of developing clinical diagnostic criteria, diagnostic strategies under clinical research, developing blood based-biomarker assays, and promising nanotechnologically-based assays.
The role of the routine pre-operative electrocardiogram in the elderly surgical patient.

In a group of 222 general surgical patients aged 65 years and over, only 21% had a normal preoperative electrocardiogram (e.c.g.) and 53% had a major pre-operative e.c. g. abnormality. The clinical significance of these findings was evaluated by observing the post-operative cardiovascular complications and e.c. g. changes which occurred. It was concluded that a routine pre-operative e.c. g. should be carried out in all elderly surgical patients (1) as a baseline measurement to aid interpretation of post-operative e.c. g. changes and (2) as a means of detecting patients with acute myocardial infarctions or serious arrhythmias in whom surgery should be deferred. As a method of predicting post-operative cardiovascular complications, however, the pre-operative e.c. g. appears to be of no value in elderly men and of only limited value in elderly women.
One Step Forwards in Knowledge of Blossom Blight Brown Rot Disease: Monilinia spp. SSR Marker Database

A freely available Monilinia spp. marker database was created, containing microsatellite (SSR) data of the three most essential European fungal pathogens: M. fructigena, M. laxa, and M. fructicola. These pathogens cause brown rot blossom blight. Microsatellites were identified using the bioinformatics tool Genome-wide Microsatellite Analyzing Toward Application (GMATA). The database provides information about SSR markers: forward and reverse sequences of the primers, fragment sizes, SSR motifs (and repeats), and the exact locations with the coordinates in the reference genome. This database currently contains information about 39,216 SSR motifs and 26,366 markers. In total, eight primers generated in silico were validated experimentally and they are marked in the database. All scientists can join this collaboration by adding their experimental data. This database is the initial start of organizing Monilinia spp. molecular data worldwide and, in the future, it could be extended by adding more molecular and genomic information.
