Fabrications of gated field emitter array (FEA), such as Si-FEA and Spindt-type FEA, is overviewed from the conventional method to the latest one. The invention of an etch-back method makes it possible to form the gate electrode on the emitter tip, irrespective of the emitter shape, and also possible to form the multi-stacked gate electrode for beam focusing. A hafnium carbide coating can enhance the electron emission and emission lifetime, significantly. The historical Spindt-type FEA fabrication is also progressing. Using a double-layered photoresist, instead of aluminum parting layer, makes it possible to apply the multi-gate formation even on the Spindttype FEA. These FEAs are applicable for many kinds of attractive devices, such as ultra-high sensitive image sensor, radiation tolerant electronics, and stationary X-ray source for medical applications.

We propose a new generic framework for constructing fully secure attribute based encryption (ABE) in multilinear settings. It is applicable in a generic manner to any predicates. Previous generic frameworks of this kind are given only in bilinear group settings, where applicable predicate classes are limited. Our framework provides an abstraction of dual system paradigms over composite-order graded multilinear encoding schemes in a black-box manner. As applications, we propose new fully secure ABE systems for general predicates, namely, ABE for circuits. We obtain two schemes for each of key-policy (KP) and ciphertext-policy (CP) variants of ABE. All of our four fully secure schemes can deal with unbounded-size circuits, while enjoy succinctness, meaning that the key and ciphertext sizes are (less than or) proportional to corresponding circuit sizes. In the CP-ABE case, no scheme ever achieves such properties, even when considering selectively secure systems. Furthermore, our second KP-ABE achieves constant-size ciphertexts, whereas our second CP-ABE achieves constant-size keys. Previous ABE systems for circuits are either selectively secure (Gorbunov et al. STOC’13, Garg et al. Crypto’13, and subsequent works), or semi-adaptively secure (Brakerski and Vaikuntanathan Crypto’16), or fully-secure but not succinct and restricted to bounded-size circuits (Garg et al. ePrint 2014/622, and Garg et al. TCC’16-A). © International Association for Cryptologic Research 2017.

Although the brominated flame retardant 1,2,5,6,9,10-hexabromocyclododecane (HBCD) has been widely used to reduce the flammability of polymeric materials, it is a toxic and persistent organic compound. In this paper, we report an efficient method for the debromination of HBCD by using a Pd-catalyzed system. HBCD was completely debrominated to the C12 cyclic compounds such as cyclododecatriene, cyclododecadiene, and cyclododecene in a solution of 2-propanol/methanol (99:1, v/v) containing dissolved NaOH in the presence of a silica-supported Pd catalyst (Pd/SiO2) at 35 °C. The reaction achieved product yields of 92% for the bromine-free products and 94% for the released Br ions. In the absence of Pd/SiO2, HBCD was partially debrominated to yield penta-, tetra-, and tribrominated C12 cyclic compounds. The HBCD debromination pathway seems to involve both HBr elimination by reaction with NaOH and Pd-catalyzed hydrodebromination by hydrogen transfer from 2-propanol. © 2017 Elsevier Ltd

The synchronized magnetization dynamics in ferromagnets on a nonmagnetic heavy metal caused by the spin Hall effect is investigated theoretically. The direct and inverse spin Hall effects near the ferromagnetic/nonmagnetic interface generate longitudinal and transverse electric currents. The phenomenon is known as the spin Hall magnetoresistance effect, whose magnitude depends on the magnetization direction in the ferromagnet due to the spin transfer effect. When another ferromagnet is placed onto the same nonmagnet, these currents are again converted to the spin current by the spin Hall effect and excite the spin torque to this additional ferromagnet, resulting in the excitation of the coupled motions of the magnetizations. The in-phase or antiphase synchronization of the magnetization oscillations, depending on the value of the Gilbert damping constant and the field-like torque strength, is found in the transverse geometry by solving the Landau-Lifshitz-Gilbert equation numerically. On the other hand, in addition to these synchronizations, the synchronization having a phase difference of a quarter of a period is also found in the longitudinal geometry. The analytical theory clarifying the relation among the current, frequency, and phase difference is also developed, where it is shown that the phase differences observed in the numerical simulations correspond to that giving the fixed points of the energy supplied by the coupling torque. © 2017 American Physical Society.

It is known that intensity interferometry, also referred to as Hanbury Brown-Twiss interferometry, prompted the emergence of modern quantum optics and has become a standard tool for measuring the quantum feature of light in various quantum optics experiments. However, it still provides new insights into correlations between intensity fluctuations in classical optical fields and finds a wide range of applications within the framework of classical optics. In this article we present an overview of recent findings and up-to-date applications associated with intensity interferometry with classical light. The topics that this article covers are limited but are designed to provide new insights into the phenomena associated with classical optics. Specifically, focuses on recent formulations of the Hanbury Brown-Twiss effect with classical electromagnetic beams and some of their consequences. and are concerned with modern applications of classical intensity interferometry, namely, ghost imaging and diffraction with classical light and classical counterparts of quantum optical coherence tomography, respectively.

A novel technique is proposed and demonstrated for measuring the temporal waveforms of phase/frequency-modulated lights based on self-heterodyne interferometry with a delay time much shorter than the modulation period and on the unwrapped phase detection of heterodyne beat signals with real-time vector signal analysis. The technique makes use of an approximated relationship between the beat signal phase and the instantaneous frequency of modulated lights. The results of waveform measurements are presented for directly frequency-modulated and externally phase-modulated lights, which have been commonly employed for FWCW-LIDAR and serrodyne frequency translation, respectively. The temporal waveforms of triangular modulation are successfully measured with a frequency deviation as large as 15 GHz and the detailed investigation is presented on the deviation of measured waveform from ideal ones. © 2017 Optical Society of America.

A new centrosymmetric D-π-D molecule, TTF-CH=CH-CH=CH-CH=CH-TTF (1, TTF: tetrathiafulvalene) was synthesized and its absorption and fluorescence solvatochromic behaviors were compared with those of Me2NPh-CH=CH-CH=CH-CH=CH-PhNMe2 (2). The lowest-energy absorption band of 1 shifts to blue as the solvent polarity increases. The wavenumber of the maximum peak correlates well with the Onsager polarity function f(ε)−f(n2)=(ε−1)/(2ε+1)−(n2−1)/(2n2+1). Considering the non-dipolar nature of 1 due to its highly symmetric structure, we conclude that the observed negative solvatochromism is related to the quadrupole (solute)-dipole (solvent) electrostatic interaction. For 2, we see the trend of positive solvatochromic shift, although the absorption maximum correlates only very weakly with f(n2). The result suggests that the solvatochromism is mainly related to the dispersion-like interaction. The different absorption solvatochromic behaviors of 1 and 2 can be attributed to the strong quadrupole character of 1 relative to that of 2, resulting from very strong donating ability of TTF. As for the fluorescence, positive solvatochromism is similarly observed for 1 and 2. The emission maxima correlate fairly well with f(ε)−f(n2). Most probably, molecules 1 and 2 experience the excited-state symmetry breaking with possible geometrical relaxation from non-dipolar Frank-Condon states to dipolar, charge transfer emitting states at least in polar solvents. © 2017 Elsevier B.V.

A Monte Carlo simulation was performed for an infinite plane medium containing spherical particles as well as a chiral component. The optical activity shifts patterns in the two-dimensional map of the effective scattering Mueller matrix in the azimuthal direction. The reduced effective matrix obtained by the simulation approximately satisfies reciprocity in spite of the theoretical prediction. The pattern shifts are explained by the mixing of elements of the reduced effective Mueller matrix owing to multiplication of two rotation matrices. The reduced effective matrix was factorized using the Lu-Chipman polar decomposition affording the polarization components as a function of the distance. The functions as a retarding linear diattenuator of the medium decreases, whereas the optical rotation increases, as the distance increases. The estimated specific rotation on the medium surface is 1.6 times larger than the specific rotation in the medium used in the simulation. © 2016 Elsevier B.V.

I report the development of (E)-2,2'-(5-(2-(4-(dicyanomethylene)-6-methyl-4H-pyran-2-yl)vinyl)-2-hydroxy benzylazanediyl)diacetic acid Fe(II) complex (1-Fe2+), a fluorescent reagent that can be used to detect dopamine. 1-Fe2+ was constructed using the cyanopyranyl group as the fluorophore and an Fe2+ complex both as the ligand exchange site and fluorescence quenching moiety. In contrast to the weak fluorescence emission of 1-Fe2+ in the absence of dopamine, a much stronger fluorescence emission was observed following the addition of dopamine owing to the release of Fe2+ from compound 1, which indicates significant fluorescence enhancement and the binding of Fe2+ to dopamine. The fluorescence intensities of the reagent were plotted as a function of the dopamine concentration and a good linear relationship was observed. The reaction of 1-Fe2+ with dopamine was not affected by the presence of foreign substances, thereby allowing for the highly selective detection of dopamine. The experimental results clearly showed that 1-Fe2+ is a good dopamine indicator, and it can be widely employed in dopamine detection protocols. © 2016 Elsevier B.V.

The electrochemical and electromechanical properties of actuators based on an ionic fluoropolymer (Nafion™) and non-ionic fluoropolymer (poly(vinylidene fluoride-co-hexafluoropropylene) [PVdF(HFP)]) gel fabricated using a single-walled carbon nanotube (SWCNT)-an ionic liquid (IL) gel electrode, were compared with those of actuators based on a non-ionic fluoropolymer (PVdF(HFP)). The ionic conductivity of the Nafion™-PVdF(HFP)-IL gel electrolyte was lower than that of the PVdF(HFP)-IL gel electrolyte. We assume that an ion complex exists between the Nafion™ SO3 - anions and imidazolium cations but not between PVdF(HFP) and the imidazolium cations. This Nafion™-PVdF(HFP)-IL gel hybrid actuator mechanism resembled that of an ionic-polymer-metal composite actuator, where the IL molecules move with the IL cations and anions. The maximum strain and maximum generated stress for the Nafion™-PVdF(HFP)-SWCNT actuator with a PVdF(HFP) : Nafion™ ratio of 1 : 3 and a bis(trifluoromethanesulfonyl)imide-containing IL were approximately 1.6 and 1.5 times higher, respectively, than the corresponding values for the PVdF(HFP)-SWCNT-IL actuator. These results indicate that ionic and non-ionic fluoropolymer-based actuators outperform non-ionic fluoropolymer-based actuators and are highly suitable for practical applications. In addition, the frequency dependence of the displacement response of the ionic and non-ionic fluoropolymer-SWCNT-IL actuator was successfully simulated using an electrochemical kinetic model. The results yielded the strain in the low-frequency limit, which was related to the electromechanical mechanism involved, and the time constant of the response, which was represented by an equivalent circuit with the ionic resistance and double-layer capacitance in series, in contrast to the non-ionic fluoropolymer-SWCNT-IL actuator represented by the electronic and ionic resistance and double-layer capacitance. © The Royal Society of Chemistry.

The purpose of this study is to quantify performances of a plain fin-and-tube heat exchanger based on a computational fluid dynamics (CFD) technique. This study employs a novel turbulence model-free approach to obtain exact numerical predictions and to avoid numerical uncertainties caused by the models. It applies three open-source software packages for conducting a series of CFD processes. The present CFD approach implements a total of 6.7×106 meshes to discretize the governing equations with the aid of viscous-layer meshes for fine-scale resolution, especially near the two flat-plate fins. The inlet air flow velocity is varied from 0.25 to 8.0ms−1, and the numerical results are compared with the laboratory measurements conducted under an equivalent experimental condition. The results of air flow visualizations show that the air flows can be categorized into three flow regimes, (1) a steady-state laminar flow, (2) an unsteady flow with periodic fluctuations, and (3) a turbulent flow with random fluctuations. This study identifies the critical Reynolds numbers for the transitions from (1) to (2) at ReD≈4000, and from (2) to (3) at ReD≈6000. The present numerical work also predicts the pressure drops and the heat transfer coefficients within an acceptable margin of errors. The fact demonstrates the potential usefulness and suitability of the present numerical approach for practical thermal engineering problems. It is concluded that the present simulation technique is beneficial to introduce for advanced design and optimization of heat transfer equipment with minimized numerical uncertainties. © 2017 Elsevier Ltd

Chaperonin is categorized as a molecular chaperone and mediates the formation of the native conformation of proteins by first preventing folding during synthesis or membrane translocation and subsequently by mediating the step-wise ATP-dependent release that result in proper folding. In the GroEL-GroES complex, a single heptameric GroEL ring binds one GroES ring in the presence of ATP/ADP, in this vein, the double ring GroEL tetradecamer is present in two distinct types of GroEL-GroES complexes: asymmetric 1:1 “bullet”-shaped GroEL:GroES and symmetric 1:2 “football” (American football)-shaped GroEL:GroES2. There have been debates as to which complex is critical to the productive protein folding mediated by the GroEL-GroES complex, and how GroES coordinates with GroEL in the chaperonin reaction cycle in association with regulation by adenine nucleotides and through the interplay of substrate proteins. A lot of knowledge on chap-eronins has been accumulating as if expanding as ripples spread around the GroEL-GroES from Escherichia coli. In this article, an overview is presented on GroEL and the GroEL- GroES complex, with emphasis on their morphological variations, and some potential applications to the fabrication of nanocomposites using GroEL as a nano-block. In parallel, a guideline is presented that supports the recognition that the E. coli and its GroEL-GroES complex do not always receive in standard literature because the biochemical features of chaperonins derived from others special, such as mammals, are not always the same as those confirmed using GroEL-GroES derived from E. coli. © Springer International Publishing Switzerland 2017.

Vitamin D supplements protect against acute respiratory infections including colds and flu, according to a study led by Queen Mary University of London (QMUL) Vitamin D supplements protect against acute respiratory infections including colds and flu, according to a study led by Queen Mary University of London (QMUL). The study provides the most robust evidence yet that vitamin D has benefits beyond bone and muscle health, and could have major implications for public health policy, including the fortification of foods with vitamin D to tackle high levels of deficiency in the UK. The results, published in the BMJ, are based on a new analysis of raw data from around 11,000 participants in 25 clinical trials conducted in 14 countries including the UK, USA, Japan, India, Afghanistan, Belgium, Italy, Australia and Canada. Individually, these trials yielded conflicting results, with some reporting that vitamin D protected against respiratory infections, and others showing no effect. Lead researcher Professor Adrian Martineau from QMUL said: "This major collaborative research effort has yielded the first definitive evidence that vitamin D really does protect against respiratory infections. Our analysis of pooled raw data from each of the 10,933 trial participants allowed us to address the thorny question of why vitamin D 'worked' in some trials, but not in others. "The bottom line is that the protective effects of vitamin D supplementation are strongest in those who have the lowest vitamin D levels, and when supplementation is given daily or weekly rather than in more widely spaced doses. "Vitamin D fortification of foods provides a steady, low-level intake of vitamin D that has virtually eliminated profound vitamin D deficiency in several countries. By demonstrating this new benefit of vitamin D, our study strengthens the case for introducing food fortification to improve vitamin D levels in countries such as the UK where profound vitamin D deficiency is common." Vitamin D - the 'sunshine vitamin' - is thought to protect against respiratory infections by boosting levels of antimicrobial peptides - natural antibiotic-like substances - in the lungs. Results of the study fit with the observation that colds and 'flu are commonest in winter and spring, when levels of vitamin D are at their lowest. They may also explain why vitamin D protects against asthma attacks, which are commonly triggered by respiratory viruses. Daily or weekly supplementation halved the risk of acute respiratory infection in people with the lowest baseline vitamin D levels, below 25 nanomoles per litre (nmol/L). However, people with higher baseline vitamin D levels also benefited, although the effect was more modest (10 per cent risk reduction). Overall, the reduction in risk of acute respiratory infection induced by vitamin D was on a par with the protective effect of injectable 'flu vaccine against 'flu-like illnesses. Acute respiratory infections are a major cause of global morbidity and mortality. Upper respiratory infections such as colds and 'flu are the commonest reason for GP consultations and days off work. Acute lower respiratory infections such as pneumonia are less common, but caused an estimated 2.65 million deaths worldwide in 2013. Vitamin D supplementation is safe and inexpensive, so reductions in acute respiratory infections brought about by vitamin D supplementation could be highly cost-effective. The study was conducted by a consortium of 25 investigators from 21 institutions worldwide* and funded by the National Institute for Health Research.
