Advanced materials for solid-state refrigeration (2013)

Recent progress on caloric effects are reviewed. The application of external stimuli such as magnetic field, hydrostatic pressure, uniaxial stress and electric field give rise respectively to magnetocaloric, barocaloric, elastocaloric and electrocaloric effects. The values of the relevant quantities such as isothermal entropy and adiabatic temperature-changes are compiled for selected materials. Large values for these quantities are found when the material is in the vicinity of a phase transition. Quite often there is coupling between different degrees of freedom, and the material can exhibit cross-response to different external fields. In this case, the material can exhibit either conventional or inverse caloric effects when a field is applied. The values reported for the many caloric effects at moderate fields are large enough to envisage future application of these materials in efficient and environmental friendly refrigeration.
On the Reliability of Half-Cell Tests for Monovalent (Li+, Na+) and Divalent (Mg2+, Ca2+) Cation Based Batteries (2017)

A comprehensive study is reported entailing a comparison of Li, Na, K, Mg, and Ca based electrolytes and an investigation of the reliability of electrochemical tests using half-cells. Ionic conductivity, viscosity, and Raman spectroscopy results point to the cationsolvent interaction to follow the polarizing power of the cations, i.e. Mg2+ &amp;gt; Ca2+ &amp;gt; Li+ &amp;gt; Na+ &amp;gt; K+ and to divalent cation based electrolytes having stronger tendency to form ion pairs - lowering the cation accessibility and mobility. Both increased temperature and the use of anions with delocalized negative charge, such as TFSI, are effective in mitigating this issue. Another factor impeding the divalent cations mobility is the larger solvation shells, as compared to those of monovalent cations, that in conjunction with stronger solvent - cation interactions contribute to slower charge transfer and ultimately a large impedance of Mg and Ca electrodes. An important consequence is the non-reliability of the pseudo-reference electrodes as these present both significant potential shifts as well as unstable behaviors. Finally, experimental protocols in order to achieve consistent results when using half-cell set-ups are proposed.
Highly Transparent Superhydrophobic Surfaces from the Coassembly of Nanoparticles (≤100 nm) (2011)

We report a simple and versatile approach to creating a highly transparent superhydrophobic surface with dual-scale roughness on the nanoscale. 3-Aminopropyltrimethoxysilane (APTS)-functionalized silica nanoparticles of two different sizes (100 and 20 nm) were sequentially dip coated onto different substrates, followed by thermal annealing. After hydrophobilization of the nanoparticle film with (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trichlorosilane for 30 min or longer, the surface became superhydrophobic with an advancing water contact angle of greater than 160° and a water droplet (10 μL) roll-off angle of less than 5°. The order of nanoparticles dip coated onto the silicon wafer (i.e., 100 nm first and 20 nm second or vice versa) did not seem to have a significant effect on the resulting apparent water contact angle. In contrast, when the substrate was dip coated with monoscale nanoparticles (20, 50, and 100 nm), a highly hydrophobic surface (with an advancing water contact angle of up to 143°) was obtained, and the degree of hydrophobicity was found to be dependent on the particle size and concentration of the dip-coating solution. UV-vis spectra showed nearly 100% transmission in the visible region from the glass coated with dual-scale nanoparticles, similar to the bare one. The coating strategy was versatile, and superhydrophobicity was obtained on various substrates, including Si, glass, epoxy resin, and fabrics. Thermal annealing enhanced the stability of the nanoparticle coating, and superhydrophobicity was maintained against prolonged exposure to UV light under ambient conditions.
The novel approach to coupled mode parameters recovery from microwave resonator amplitude-frequency response (2011)

We propose a new procedure of processing of amplitude-frequency response (AFR) for the purpose of recovering complete set of normal and partial parameters of coupled modes in microwave resonators. The normal parameters are calculated by means of approximating AFR by squared sum of complex amplitudes of both modes. The partial parameters are determined from analysis of lumped-element equivalent circuit of the resonator. Verification of the technique was carried out on mode simulation results in the coupled cavities. As an example, applicability of the technique for characterization of high-T<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</inf> materials is shown under conditions of the mode partial degeneration removal.

An optimization model of load balancing in Peer to Peer (P2P) Network (2011)

In this work, an optimization model of load balancing in P2P network is proposed to make full use of each node resource, and to consider the coordination of network resource allocation between the other network area and this area, making the whole network resource can be used as fully as possible, based on the load information of the different nodes, we layer the nodes and use an undirected graph to link each node. We put the ratio that come from the adding two nodes load capacity divided by the volume of the optimal load between the adjacent nodes as the strength of the road weights. When node load need several nodes to finish at the same time, find the optimal path of transfer load doing load transfer. And in need not considering several nodes load transfer, we can accord to the information of node list record to load or to join the node. It can optimize the load balancing in Peer to Peer Network and achieve high speed, it also can reduce the cost of load delay.
Membranes as Structural Antioxidants (2016)

Genetic evidence suggests that membranes rich in polyunsaturated fatty acids (PUFAs) act as supramolecular antioxidants that capture reactive oxygen species, thereby limiting damage to proteins. This process generates lipid fragmentation products including malondialdehyde (MDA), an archetypal marker of PUFA oxidation. We observed transient increases in levels of endogenous MDA in wounded Arabidopsis thaliana leaves, raising the possibility that MDA is metabolized. We developed a rigorous ion exchange method to purify enzymatically generated (13)C- and (14)C-MDA. Delivered as a volatile to intact plants, MDA was efficiently incorporated into lipids. Mass spectral and genetic analyses identified the major chloroplast galactolipid: α-linolenic acid (18:3)-7Z,10Z,13Z-hexadecatrienoic acid (16:3)-monogalactosyldiacylglycerol (18:3-16:3-MGDG) as an end-product of MDA incorporation. Consistent with this, the fad3-2 fad7-2 fad8 mutant that lacks tri-unsaturated fatty acids incorporated (14)C-MDA into 18:2-16:2-MGDG. Saponification of (14)C-labeled 18:3-16:3-MGDG revealed 84% of (14)C-label in the acyl groups with the remaining 16% in the head group. 18:3-16:3-MGDG is enriched proximal to photosystem II and is likely a major in vivo source of MDA in photosynthetic tissues. We propose that nonenzymatically generated lipid fragments such as MDA are recycled back into plastidic galactolipids that, in their role as cell protectants, can again be fragmented into MDA.
D-Swoosh: A Family of Algorithms for Generic, Distributed Entity Resolution (2007)

Entity resolution (ER) matches and merges records that refer to the same real-world entities, and is typically a compute-intensive process due to complex matching functions and high data volumes. We present a family of algorithms, D-Swoosh, for distributing the ER workload across multiple processors. The algorithms use generic match and merge functions, and ensure that new merged records are distributed to processors that may have matching records. We perform a detailed performance evaluation on a testbed of 15 processors. Our experiments use actual comparison shopping data provided by Yahoo!.
A Genetic Algorithm-Based Antenna Selection Approach for Large-but-Finite MIMO Networks (2016)

We study the performance of antenna selection-based multiple-input-multiple-output networks with large-but-finite number of transmit antennas and receivers. Considering the continuous and bursty communication scenarios with different users' data request probabilities, we develop an efficient antenna selection scheme using genetic algorithms (GAs). As demonstrated, the proposed algorithm is generic in the sense that it can be used in the cases with different objective functions, precoding methods, levels of available channel state information, and channel models. Our results show that the proposed GA-based algorithm reaches (almost) the same throughput as the exhaustive search-based optimal approach, with substantially less implementation complexity.
Advances in genetic testing for Alzheimer's disease. (2009)

As the prevalence of Alzheimer's disease (AD), the most common dementia in the elderly, continues to increase, neurologists will encounter a growing number of questions about genetic testing for dementia patients, their relatives, and people concerned about memory or cognitive function who have no apparent risk except advancing age. Until recently, clinical gene testing only included apolipoprotein E genotyping and testing for presenilin 1 mutations. In 2008, testing expanded to include the presenilin 2 and amyloid precursor protein genes. Despite these advances, genetic testing is currently not appropriate for most individuals diagnosed with AD and has limited utility for predictive purposes. Further research, however, is likely to expand the usefulness of this testing for both dementia patients and their relatives. If genetic testing is undertaken, thorough counseling, whether by the physician or a qualified genetic counselor, is an integral component of the testing process for both affected individuals and their families.
Flavanol metabolites reduce monocyte adhesion to endothelial cells through modulation of expression of genes via p38‐MAPK and p65‐Nf‐kB pathways (2014)

Our study provides findings into the molecular mechanisms by which plasma flavanol metabolites could be efficient to preserve vascular endothelium integrity in nutritionally relevant conditions.
A new approach for modeling and control of MIMO nonlinear systems (2002)

Modeling of nonlinear systems is implemented using a partial linear modeling (PLM) technique, which separates the linear and nonlinear part of the model. The linear part of the model is in the form of an ARX model, while the nonlinear part is in the form of NNARX model using an RBF neural network. For the RBF neural network, the centers of the network are chosen using an orthogonal least squares (OLS) method. The linear part of the model is constructed to fit and absorb as much as possible the dynamic of the system, while its residuals are fitted using the nonlinear part of the model. The model is tested on experimental data of a MIMO spark ignition (SI) engine system. The plant (SI engine) is handled as a two-inputs, two-outputs process, the two inputs are the ignition timing and the throttle angle, the two outputs are the engine speed and manifold pressure. Different order and nonlinear terms of model are tested on the input-output data to obtain a valid model. Finally, second order with three nonlinear terms of model is found as a fairly accurate model. Model validation is treated using different sets of input-output data which indicates that the resulting model is fairly valid. A feedback linearization method is used for controlling the nonlinear system where the model is constructed using the PLM technique. The smooth transition of the controller output shows that the combination of the modeling and control technique has real potential for real-time implementation.
Coherent transfer of electron spin correlations assisted by dephasing noise (2018)

Quantum coherence of superposed states, especially of entangled states, is indispensable for many quantum technologies. However, it is vulnerable to environmental noises, posing a fundamental challenge in solid-state systems including spin qubits. Here we show a scheme of entanglement engineering where pure dephasing assists the generation of quantum entanglement at distant sites in a chain of electron spins confined in semiconductor quantum dots. One party of an entangled spin pair, prepared at a single site, is transferred to the next site and then adiabatically swapped with a third spin using a transition across a multi-level avoided crossing. This process is accelerated by the noise-induced dephasing through a variant of the quantum Zeno effect, without sacrificing the coherence of the entangled state. Our finding brings insight into the spin dynamics in open quantum systems coupled to noisy environments, opening an avenue to quantum state manipulation utilizing decoherence effects.
Electric storage in de-alloyed Si-Al alloy ribbons (2012)

\n\nThe capacitance of de-alloyed Si1−xAlx (x = 0.2, 0.3, and 0.4) alloy ribbons with resistivities of 1–1000 Ωcm was measured as a function of frequency between 1 mHz and 1 MHz from electric charge/discharge pulse curves of 10 V applied at 100 ms–25 ns intervals, respectively, using an exponential transient analysis for electric charging/discharging. The capacitance of the de-alloyed Si-20 at.% Al specimen obtained by prompt charging/discharging decreased logarithmically from 102 μF (0.55 F/cm3) to 1.2 pF (53 nF/cm3) as frequency increased from 1 mHz to 1 MHz. From the observed electrode distance dependence on capacitance and nonlinear electronic transport behaviour, we deduced that the alloy consisted in a distributed constant equivalent circuit (series with 1.7% parallel), analogous to electric double-layer capacitors.\n
Structure and properties of the system: poly(2,6-dimethyl-phenylene oxide) isotactic polystyrene. Wide-angle x-ray studies (1975)

PPO/iPS blends of various compositions have been crystallized isothermally and by solvent-induced treatment from the glassy state. The crystallinity as a function of composition has been determined from the integral scattering of the crystalline and amorphous regions. Applying Hosemann’s concept of the paracrystal, crystallite size and strain parameters have been calculated from peak broadening analysis. The results are compared to those obtained from DSC and small-angle x-ray measurements on the same samples.
A fast discrete transform architecture for Frequency Domain Motion Estimation (2010)

Frequency Domain Motion Estimation (FDME) is a recent technique that promises to efficiently reduce the computational complexity of ME process. Related Transformed-Discrete Cosine Transform (RT-DCT) is one of the main modules that build the FDME encoder. The RT-DCT module is responsible for generating four transforms that are required for the ME process in the frequency domain. The main problem of generating such transforms is the low speed of the FDME encoder that prevents its use in real time applications. In this paper an efficient fast RT-DCT architecture is proposed to accelerate the encoding process in the frequency domain. The proposed architecture achieves approximately 58%, 39%, and 50% reductions in gate count, power consumption, and area compared to the conventional state of the art pipelined RT-DCT generators. Implementation and Simulation results project that the proposed RT-DCT architecture, when integrated in a whole FDME system, can perform ME for 60 fps of 4CIF video at 118 MHz.

New Ruthenium Catalysts for Asymmetric Transfer Hydrogenation of Prochiral Ketones (2007)

Abstract Tridentate N,N,N ‐pyridinebisimidazolines have been studied as new ligands for the enantioselective transfer hydrogenation of prochiral ketones. High yields and excellent enantioselectivity up to &gt;99 % ee have been achieved with an in situ generated catalytic system containing dichlorotris(triphenylphosphine)ruthenium and 2,6‐bis‐([ 4R,5R ]‐4,5‐diphenyl‐4,5‐dihydro‐1 H ‐imidazol‐2‐yl)‐pyridine ( 3a ) in the presence of sodium isopropoxide.
Acute phase reaction, heterogeneity, and microheterogeneity of serum proteins as nonspecific tumor markers in lung cancer (1987)

The acute phase proteins, orosomucoid, ceruloplasmin, antitrypsin, and haptoglobin were measured in serum from 54 patients with lung cancer, 16 patients with benign lung inflammation, and 30 healthy individuals. A statistical correlation was found between tumor size and acute phase protein level, which, however, was ascribed to nonspecific inflammation in the tissues surrounding the tumor. The patients who subsequently could not be radically treated by surgery had higher concentrations of orosomucoid and ceruloplasmin than the radically treated patients. No difference in acute phase protein concentration was found between benign and malignant disease. The glycan-dependent microheterogeneity of orosomucoid and ceruloplasmin was analyzed by crossed affinoimmunoelectrophoresis with lectins, and the patterns of the patients with benign inflammation and malignant disease were different. The heterogeneity of ceruloplasmin was also analyzed by crossed immunoelectrophoresis without lectin. This analysis, combined with the total serum concentration of ceruloplasmin, made it possible to discriminate the 54 cases of malignancy from the 46 cases of nonmalignancy with a sensitivity of 78% and a specificity of 93%. It is suggested that the simple electrophoretic analyses of (micro-)heterogeneity is a valuable supplement to the acute phase profile in isolating high-risk patients and in monitoring radically treated cancer patients for relapse.
PSV-FLC Fabricated Using Photo-Alignment Technique (2015)

Polymer-stabilized V-mode Ferroelectric Liquid Crystals (PSV-FLCs) are attractive for a next generation of LC display. However, in the rubbing technique which is conventionally used for LC molecular alignment, the rubbing scratches form on the alignment film surface, and then, the rubbing scratch pattern is clearly observed in the texture of FLC. Therefore, the high contrast ratio cannot be obtained due to the optical leakage. In this research, we introduce the photo-alignment technique to PSV-FLC. As a result, the optical leakage can be largely suppressed by the photo-alignment technique, and thus, the photo-alignment technique is effective to PSV-FLCs.
Evolution of the nuclear receptor superfamily: early diversification from an ancestral orphan receptor (1997)

From a database containing the published nuclear hormone receptor (NR) sequences I constructed an alignment of the C, D and E domains of these molecules. Using this alignment, I have performed tree reconstruction using both distance matrix and parsimony analysis. The robustness of each branch was estimated using bootstrap resampling methods. The trees constructed by these two methods gave congruent topologies. From these analyses I defined six NR subfamilies: (i) a large one clustering thyroid hormone receptors (TRs), retinoic acid receptors (RARs), peroxisome proliferator-activated receptors (PPARs), vitamin D receptors (VDRs) and ecdysone receptors (EcRs) as well as numerous orphan receptors such as RORs or Rev-erbs; (ii) one containing retinoid X receptors (RXRs) together with COUP, HNF4, tailless, TR2 and TR4 orphan receptors; (iii) one containing steroid receptors; (iv) one containing the NGFIB orphan receptors; (v) one containing FTZ-F1 orphan receptors; and finally (vi) one containing to date only one gene, the GCNF1 orphan receptor. The relationships between the six subfamilies are not known except for subfamilies I and IV which appear to be related. Interestingly, most of the liganded receptors appear to be derived when compared with orphan receptors. This suggests that the ligand-binding ability of NRs has been gained by orphan receptors during the course of evolution to give rise to the presently known receptors. The distribution into six subfamilies correlates with the known abilities of the various NRs to bind to DNA as homo- or heterodimers. For example, receptors heterodimerizing efficiently with RXR belong to the first or the fourth subfamilies. I suggest that the ability to heterodimerize evolved once, just before the separation of subfamilies I and IV and that the first NR was able to bind to DNA as a homodimer. From the study of NR sequences existing in vertebrates, arthropods and nematodes, I define two major steps of NR diversification: one that took place very early, probably during the multicellularization event leading to all the metazoan phyla, and a second occurring later on, corresponding to the advent of vertebrates. Finally, I show that in vertebrate species the various groups of NRs accumulated mutations at very different rates.
Metabotropic glutamate receptor 5 tracer [18F]-FPEB displays increased binding potential in postcentral gyrus and cerebellum of male individuals with autism: a pilot PET study (2018)

These novel findings demonstrate for the first time that mGluR5 binding is altered in critical brain areas of subjects with autism, suggesting abnormal glutamate signaling in these regions. Finally, the correlations between altered [<sup>18</sup>F]-FPEB binding potential in the cerebellum and precuneus suggest that some autistic symptoms may be influenced by abnormal glutamate signaling.
