Enhancing thermal radiation with nanoantennas to create infrared sources with high modulation rates

In recent decades, researchers have demonstrated incandescent sources that exhibit monochromatic, directional, and even fast modulated infrared emission. Most of the researchers achieve this type of emission by heating the whole device. Here, we propose heating only nanovolumes that can be cooled in a few tens of nanoseconds. This approach could enable high-speed modulation. To compensate for the weak thermal emission of such isolated nanoemitters, we propose inserting the hot nanovolume in the gap of a cold nanoantenna. We calculate the resulting emission enhancement by using a generalized version of Kirchhoff’s law, and demonstrate that careful design of the complete antenna–nanoemitter system can result in emission enhancements of more than four orders of magnitude.
Cardiovascular Topics Oxidative metabolism of neutrophils in acute coronary syndrome

Background: Inflammation in acute coronary syndrome (ACS) involves neutrophil activation and oxidative stress. Here, we studied the production of reactive oxygen species (ROS) by neutrophils in ACS. Methods: The study included 42 patients, men and women aged 46–91 years with ischaemic heart disease (IHD), non-ST-segment elevation ACS and ST-segment elevation ACS. Neutrophil-derived ROS were quantified with double-step stimulated luminol-enhanced chemiluminometry. Results: The specific indices of spontaneous and double-step stimulated chemiluminescence did not differ in the subgroups of IHD, non-ST-segment elevation ACS and ST-segment elevation ACS. The total double-step stimulated ROS production by neutrophils was significantly higher in ST-segment elevation ACS than in non-ST-segment elevation ACS and IHD. Conclusions: In ACS, special activation mechanisms of peripherical neutrophils were not triggered in our study. The significant increase in free radical production by neutrophils in acute myocardial infarction was presumably a consequence of an increase in their number.
Deep Multimodal Clustering for Unsupervised Audiovisual Learning

The seen birds twitter, the running cars accompany with noise, etc. These naturally audiovisual correspondences provide the possibilities to explore and understand the outside world. However, the mixed multiple objects and sounds make it intractable to perform efficient matching in the unconstrained environment. To settle this problem, we propose to adequately excavate audio and visual components and perform elaborate correspondence learning among them. Concretely, a novel unsupervised audiovisual learning model is proposed, named as Deep Multimodal Clustering (DMC),that synchronously performs sets of clustering with multimodal vectors of convolutional maps in different shared spaces for capturing multiple audiovisual correspondences. And such integrated multimodal clustering network can be effectively trained with max-margin loss in the end-to-end fashion. Amounts of experiments in feature evaluation and audiovisual tasks are performed. The results demonstrate that DMC can learn effective unimodal representation, with which the classifier can even outperform human performance. Further, DMC shows noticeable performance in sound localization, multisource detection, and audiovisual understanding.
Hydatid Cyst in Proximal Femur: A Case Report

Hydatid cysts, caused by the larval stage of the tapeworm Echinococcus Granulosus, are rare in the musculoskeletal system. We present a unique case of a hydatid cyst found in the proximal femur / hip joint of a patient with an implanted hip prosthesis. A 75-years old male with a history of cemented Hemi-arthroplasty (Thompson prosthesis) presented with hip pain and limited (painful) range of motion of the hip. Radiologically osteolysis was appreciated, suggestive of implant loosening. Surgical intervention was done. Per-operative cystic lesions were found. Clinical diagnosis of Hydatid disease was made and the cysts were successfully treated with Hypertonic saline and albendazole. Histopathological examination confirmed the diagnosis of Hydatid cyst. This case highlights the importance of considering Hydatid cyst as a rare, differential diagnosis in patients even with a prosthetic joint, residing especially in endemic regions of the world, which would require multidisciplinary approach for their management.
Characteristics of Future Changes in Summertime East Asian Monthly Precipitation in MRI-AGCM Global Warming Experiments

Global warming experiments using three different 60 km mesh atmospheric global circulation models are studied to characterize ensemble mean future changes in monthly East Asian precipitation for June to August. During the summer, wetting and drying effects due to changes in the mean vertical motion play a key role in future precipitation changes, as does the “wet-get-wetter” effect due to increased moisture. The former processes are related adiabatically to the projected modification of 500 hPa horizontal atmospheric circulation, which is characterized by two cyclonic circulation anomalies extending over the eastern Eurasian Continent (C1) and the western North Pacific Ocean (C2) for each month. Over Japan, the western edge of C2 shifts from a region south of the Japanese Islands to northern Japan during June to August, representing a delayed northward movement or southward shift of the westerly jet over the western North Pacific in the future compared with the present-day climatology. Most regions of Japan lie within the northeasterly wind and associated downward-motion zones of C2, leading to significant uncertainties in future precipitation over Japan by the offset against the “wet-get-wetter” effect and possibly even a future decrease in precipitation. A wetter future climate is anticipated under weak subsidence or upward vertical motion zone of C2, such as western Japan in August away from C2, and the Southwest Islands of Japan in June in the C2 southwesterly wind zone. Over the eastern Eurasian Continent, C1 is distributed mainly over northeastern China in June and over central and southern China in July and August, respectively. During these months, most of the eastern regions are located within the southwesterly to southeasterly wind zone of C1, indicating wet future conditions due to enhanced upward motion. This tendency drives a further increase in precipitation in future wetter East Asian climate via the “wet-get-wetter” effect and the increased evaporation.
3D Co-Printing and Substrate Geometry Influence the Differentiation of C2C12 Skeletal Myoblasts

Cells are influenced by several biomechanical aspects of their microenvironment, such as substrate geometry. According to the literature, substrate geometry influences the behavior of muscle cells; in particular, the curvature feature improves cell proliferation. However, the effect of substrate geometry on the myogenic differentiation process is not clear and needs to be further investigated. Here, we show that the 3D co-printing technique allows the realization of substrates. To test the influence of the co-printing technique on cellular behavior, we realized linear polycaprolactone substrates with channels in which a fibrinogen-based hydrogel loaded with C2C12 cells was deposited. Cell viability and differentiation were investigated up to 21 days in culture. The results suggest that this technology significantly improves the differentiation at 14 days. Therefore, we investigate the substrate geometry influence by comparing three different co-printed geometries—linear, circular, and hybrid structures (linear and circular features combined). Based on our results, all structures exhibit optimal cell viability (>94%), but the linear pattern allows to increase the in vitro cell differentiation, in particular after 14 days of culture. This study proposes an endorsed approach for creating artificial muscles for future skeletal muscle tissue engineering applications.
Nano-Hydroxyapatite Isolation and Characterisation of Echinometra mathaei from the Persian Gulf

The study focuses on the preparation and characterisation (physicochemical and mechanical) of hydroxyapatite [Ca10(PO4)6(OH)2] (HA) from sea urchin, Echinometra mathaei. Therefore, nano-sized HA prepared from sea urchin shells were collected from beaches of the Persian Gulf in Iran. Sea urchin shells were found a source of calcium carbonate in the form of aragonite (calcite) that crystallised in an organic matrix. HA is one of the polymers used in coating the nanoparticles extracted from various sources. The calcined aragonite converted to nanosized hydroxyapatite powder by chemical reaction with orthophosphoric acid while maintaining stoichiometry, Ca/P = 1.667 at 80°C. To determine the purity of the nano-hydroxyapatite (nHA) numerous analytical procedures were used. Fourier transforms infrared spectroscopy (FTIR) confirmed the presence of the peak of 961 cm−1 is related to the symmetric tensile band of the P-O bond, and the peak of 1038 cm−1 and 1091 cm−1 is related to the tensile solid absorption of the PO4 as functional groups of nHA. The nanocrystalline HA can be observed from the SEM images. Thermogravimetric analysis (TGA-DTA) demonstrates the thermal stability of nHA powder. The results show successful isolation and characterisation study of this crucial nano-material shows it is valuable in biomedical applications, particularly in bone tissue engineering. Indeed, its fabrication is easy and economical.
A neurobiologically-inspired intelligent trajectory tracking control for unmanned aircraft systems with uncertain system dynamics and disturbance

In this paper, a novel neurobiologically-inspired intelligent tracking controller is developed and implemented for unmanned aircraft systems in the presence of uncertain system dynamics and disturbance. The methodology adopted, known as Brain Emotional Learning Based Intelligent Controller (BELBIC), is based on a novel computational model of emotional learning within brain limbic systems in mammals. Compared to conventional model-based control methods, BELBICs are more suitable for practical unmanned aircraft systems since they can maintain the real-time unmanned aircraft system performance without known system dynamics and disturbance. Furthermore, the learning capability and low computational complexity of BELBIC mean that it is very promising for implementation in complex real-time applications. Moreover, we proved that our proposed methodology guarantees convergence. To evaluate the practical performance of our proposed design, BELBIC has been implemented into a benchmark unmanned aircraft system. Numerical and experimental results demonstrated the applicability and satisfactory performance of the proposed BELBIC-inspired design.

Fuzzy goal programming technique for solving flexible assignment problem in PCB assembly line

Abstract In this paper, we construct the multiple objectives programming for the PCB line assignment problem based on the Assignment Problem (AP) and Transportation Problem (TP) models, which employs the fuzzy goal programming technique with nonlinear membership function for solving this multiple objectives programming problem. This computational mathematics has been addressed to solve an AP under uncertainty and in real world scenarios is using fuzzy theory. Fuzzy goal programming technique usually deals with flexible aspiration levels that are indicative of optimality when considering all objectives or goals simultaneously with possible deviation in objectives or constraints in vague, imprecise and uncertain environment. Therefore; the proposed model will give a compromise solution for suitable optimality and adjust the interval objective values of the upper and lower bounds of each objective function for parameters being considered in uncertain environment. Finally, a case study is taken to illustrate the solution procedure.

Basic Cardiology

Aim of the study: During heart failure (HF), mechanisms of ventricular arrhythmias are poorly understood. The clinical relevance of elementary mechanisms suggested by in vitro experiments has to be questioned, since in vivo correlations are often lacking. We compared action potential (AP) characteristics, occurrence of automaticity, and triggered activity with in vivo arrhythmic, morphologic, and haemodynamic data in post myocardial infarction (PMI) rats. Methods and results: Telemetric ECG, morphologic, and haemodynamic data were obtained from 16 live PMI and 13 sham rats, at one and five months after surgery. Action potentials (AP) were studied on the papillary muscle in different solutions, and at different pacing rates. Spontaneous ventricular premature beats (VPBs) were frequent in PMI and were bradycardia-dependent. Abnormal automaticity was the most common in vitro observed mechanism. Time after infarction was related to EAD/DAD in vitro distribution but not with in vivo data. HF induced major alterations of filling pressures and of AP characteristics. AP duration was strongly correlated with the size of infarction but not with the arrhythmic density, in contrast with AP amplitude, resting potential, and V max . Conclusion: In PMI rats, abnormal automaticity was the major mechanism of in vitro recorded arrhythmias, consistently with the bradycardia-dependence of in vivo observed VPBs. Delay after infarction influenced only EAD/DAD proportion. In this model, AP prolongation could be a simple marker of HF not involved in arrhythmogenic mechanisms. Heterogeneity of the pathobiology of arrhythmias in HF warrants further in vitro-in vivo correlations. J Clin Basic Cardiol 2005; 8: 23–8.
Sparse Low-Rank Tensor Decomposition for Metal Defect Detection Using Thermographic Imaging Diagnostics

— With the increasing use of induction thermography (IT) for non-destructive testing (NDT) in the mechanical and rail industry, it becomes necessary for the manufactures to rapidly and accurately monitor the health of specimens. The most general problem for IT detection is due to strong noise interference. In order to counter it, general post-processing is carried out. However, due to the more complex nature of noise and irregular shape specimens, this task becomes difficult and challenging. In this paper, a low-rank tensor with a sparse mixture of Gaussian (MoG) (LRTSMoG) decomposition algorithm for natural crack detection is proposed. The proposed algorithm models jointly the low rank tensor and sparse pattern by using a tensor decomposition framework. In particular, the weak natural crack information can be extracted from strong noise. Low-rank tensor based iterative sparse MoG noise modeling is carried out to enhance the weak natural crack information as well as reducing the computational cost. In order to show the robustness and efficacy of the model, experiments are conducted for natural crack detection on a variety of specimens. A comparative analysis is presented with general tensor decomposition algorithms. The algorithms are evaluated quantitatively based on signal-to-noise-ratio (SNR) along with the visual comparative analysis.
ZD Method Based Nonlinear and Robust Control of Agitator Tank

To improve industrial efficiency, an agitator tank system should have not only a short response time, but also produce reagents with accurate concentration and moderate liquid level. This paper presents a new method called Zhang dynamics (ZD) to perform tracking control, that is, to make the concentration and liquid level of the agitator tank converge to the desired trajectories. Two controllers for tracking control of an agitator tank system are designed based on ZD method. In addition, the robustness of the agitator tank system equipped with ZD controllers is investigated. Theoretical analyses on the convergence performance and robustness of the agitator tank system equipped with ZD controllers are presented. To substantiate the effectiveness of the ZD method for tracking control of the agitator tank system, we perform simulations on three different groups of tracking trajectories, which reflects the corresponding application conditions in the chemical industry. To test the robustness of the agitator tank system equipped with ZD controllers, additional simulations with different disturbances added in the agitator tank system and the ZD controllers are performed. Simulation results validate the feasibility and effectiveness of the ZD method for tracking control of the agitator tank system.
On the Adjacency, Laplacian, and Signless Laplacian Spectrum of Coalescence of Complete Graphs

Coalescence as one of the operations on a pair of graphs is significant due to its simple form of chromatic polynomial. The adjacency matrix, Laplacian matrix, and signless Laplacian matrix are common matrices usually considered for discussion under spectral graph theory. In this paper, we compute adjacency, Laplacian, and signless Laplacian energy ( energy) of coalescence of pair of complete graphs. Also, as an application, we obtain the adjacency energy of subdivision graph and line graph of coalescence from its energy.
In Vivo Anti-Vibrio Evaluation of Sponge-Associated Bacteria on the Survival Rate of Litopenaeus vannamei Infected with Pathogenic Vibrio Species

Sponge-associated bacteria are considered a rich source of bioactive compounds particularly to reduce the risk of Vibrio harveyi and Vibrio parahaemolyticus infection. The present study aimed to analyse the effectiveness of 19 isolates to control Vibrio infection in vivo. All 19 isolates displayed a non-pathogenic characteristic on shrimps (cell density of 106 cells/mL) as analysed using the pathogenicity test. The mortality caused by both Vibrio spp. on 50% of the shrimp population (LC50 value) had a cell density of 105 cells/mL as determined using the proportion interval method. On the basis of the challenge test, all isolates improved the survival rate of infected shrimps in diverse effectivities up to 89%, which was nearly 30% higher than the infected control. Two isolates coded as D6.9, and P5.20 reduced shrimp mortality after infection with Vibrio spp. 16S rRNA-based identification showed these isolates were closely similar to different genera of Bacillus and Staphylococcus. The extract derived from the most prospective isolate, D6.9, was dominated by 1-hydroxy-6-(3-isopropenyl-cycloprop-1-enyl)-6-methyl-heptan-2-one, hexadecanoic acid, 4-epicyclomusalenone [(24S)-24-methyl-28-norcycloart-25-en-3-one], and 2,4-dimethyl acetoacetanilide. This observation suggested these isolates characterised by in vivo anti-Vibrio activity need to be further developed as biocontrol candidates.

Dynamics of Large-scale Coronal Structures as Imaged during the 2012 and 2013 Total Solar Eclipses

White light images acquired at the peak of solar activity cycle 24, during the total solar eclipses of 2012 November 13 and 2013 November 3, serendipitously captured erupting prominences accompanied by CMEs. Application of state-of-the-art image processing techniques revealed the intricate details of two “atypical” large-scale structures, with strikingly sharp boundaries. By complementing the processed white light eclipse images with processed images from co-temporal Solar Dynamics Observatory/AIA and SOHO/LASCO observations, we show how the shape of these atypical structures matches the shape of faint CME shock fronts, which traversed the inner corona a few hours prior to the eclipse observations. The two events were not associated with any prominence eruption but were triggered by sudden brightening events on the solar surface accompanied by sprays and jets. The discovery of the indelible impact that frequent and innocuous transient events in the low corona can have on large-scale coronal structures was enabled by the radial span of the high-resolution white light eclipse images, starting from the solar surface out to several solar radii, currently unmatched by any coronagraphic instrumentation. These findings raise the interesting question as to whether large-scale coronal structures can ever be considered stationary. They also point to the existence of a much larger number of CMEs that goes undetected from the suite of instrumentation currently observing the Sun.
