Bandwidth-Enhanced Low-Profile Magneto-Electric Dipole Antenna With Shorting Parasitic Elements (2021)

This paper presents a low-profile magneto-electric (ME) dipole antenna with an enhanced impedance bandwidth realized by the loading of shorting parasitic elements. The antenna contains a horizontal planar electric dipole antenna, a <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\Gamma $ </tex-math></inline-formula> -shaped shorted patch antenna, a pair of parasitic L-shaped shorted patches, and a direct feed. By loading of the parasitic L-shaped patches such that they are shorted to the ground, the proposed antenna attains a significant bandwidth enhancement while maintaining excellent broadside radiation characteristics. An antenna prototype with a low profile of only <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$0.11\lambda _{0}$ </tex-math></inline-formula> was fabricated and tested ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\lambda _{0}$ </tex-math></inline-formula> is the free-space wavelength referring to the center frequency). The antenna achieves a measured impedance bandwidth of 75.64% (1.34–2.97 GHz) for a voltage standing wave ratio (VSWR) of less than 2. Within the operating band, the measured gain ranges from 6.23 to 8.49 dBi. Additionally, stable radiation patterns on both E- and H-planes with a high front-to-back ratio of more than 20.5 dB are achieved.
Human skin gene expression doesn't correlate with protein expression? Unless both parameters are quantified (2017)

Many cosmetic companies utilize in vitro gene array studies to display significant stimulation or inhibition of various human skin biomarkers to validate in vivo actions that are reported to enhance dermal health. This follows the central dogma of DNA-to-RNA results in protein expression; however, gene and protein expressions do not usually correlate. Unless both gene and protein expressions are quantified which require further investigational time and investment. Where data are available, this short commentary displays the in vitro comparison of four human skin biomarkers for the gene and protein expressions of the stimulation of collagen type I and elastin and the inhibition of matrix metalloproteinases 1 and 3, when equol was tested. The results demonstrate a good correspondence between gene and protein expressions for the human skin biomarkers tested.
Multiscale modeling of defects in semiconductors : a novel molecular-dynamics scheme (2007)

Now that the modeling of simple semiconductor systems has become reliable, accurate and routine, attention is focusing on larger scale, more complex simulations. Many of these necessarily involve multiscale aspects and can only be tackled by addressing the different length scales simultaneously. We discuss some of the types of problems that require multiscale approaches. Finally we describe the LOTF (learn-on-the-fly) hybrid scheme with a series of examples to show its versatility and power
Activation energy for surface diffusion of Si on Si(001): A scanning-tunneling-microscopy study (1991)

The migration of Si on Si(001) has been investigated by analyzing the number density of islands formed during deposition using scanning tunneling microscopy. The activation energy and prefactor for diffusion in the fast direction, which is along the surface dimer rows, are found to be 0.67\ifmmode\pm\else\textpm\fi{}0.08 eV and \ensuremath{\sim}${10}^{\mathrm{\ensuremath{-}}3}$ ${\mathrm{cm}}^{2}$/sec, respectively.
Predisposition to Proinsulin Misfolding as a Genetic Risk to Diet-Induced Diabetes (2021)

&lt;p&gt;Throughout evolution, proinsulin has exhibited significant sequence variation in both C-peptide and insulin moieties. As the proinsulin coding sequence evolves, the gene product continues to be under selection pressure both for ultimate insulin bioactivity and for the ability of proinsulin to be folded for export through the secretory pathway of pancreatic b-cells. The substitution proinsulin-R(B22)E is known to yield a bioactive insulin, although R(B22)Q has been reported as a mutation that falls within the spectrum of Mutant &lt;i&gt;INS&lt;/i&gt;-gene induced Diabetes of Youth (MIDY). Here we have studied mice expressing heterozygous (or homozygous) proinsulin-R(B22)E knocked into the &lt;i&gt;Ins2&lt;/i&gt; locus. Neither females nor males bearing the heterozygous mutation develop diabetes at any age examined, but subtle evidence of increased proinsulin misfolding in the endoplasmic reticulum is demonstrable in isolated islets from the heterozygotes. Moreover, males have indications of glucose intolerance and within a few week exposure to a high-fat diet, they develop frank diabetes. Diabetes is more severe in homozygotes, and the development of disease parallels a progressive heterogeneity of b-cells with increasing fractions of proinsulin-rich/insulin-poor cells, as well as glucagon-positive cells. Evidently, sub-threshold predisposition to proinsulin misfolding can go undetected, but provides genetic susceptibility to diet-induced b-cell failure. &lt;/p&gt;
A Note on the Channel Aware Decision Fusion in Wireless Sensor Networks (2006)

Decision fusion in wireless sensor networks under non-Gaussian noise channels is studied. Based on the parallel fusion model, the likelihood ratio (LR) based fusion rule is represented and considered as an optimal fusion rule. From this rule, we obtain suboptimum rules by utilizing high and low signal-to-noise ratio (SNR) approximations corresponding to tail and central parts of noise distributions, respectively. For the high SNR case two wide classes of distributions corresponding to two types of tails, exponentially-tailed and Pareto type distributions, and for low SNR case smooth densities in their central part are considered and studied to derive alternative rules to the LR rule with symmetric and unimodal assumptions. Performance evaluation for several fusion rules is performed through simulation
Interfacial Passivation of Nanocoatings for Corrosion Inhibition of Magnesium Alloys (2012)

In situ phosphatizing coating (ISPC) was invented and patented in 1994, where in situ phosphatizing reagent (ISPR) was shown to form a dense interfacial phosphate layer on and bond strongly with metal substrates, and simultaneously link with covalent bonds to the polymer top-layer. In this paper, we report the synthesis of ISPR-catalyzed polysilsesquioxane (PSSQ) oligomers by the sol-gel method. Using different amounts of ISPR, the well-defined nanonetwork structures of PSSQ were characterized by SEM. The dispersion of ISPR-catalyzed PSSQ in ISPC to form a stable and compatible organic-inorganic hybrid (ISPC/PSSQ) nanocoating was carried out. The nanocoating was applied on AlMg alloys (AZ31A, AZ31B and AZ91D), and the corrosion performance was characterized by salt spray test (ASTM B117) and electrochemical impedance spectroscopy (EIS). The cross-section of dry film nanocoating layer on AZ91D was characterized by TEM EDS elemental mapping analysis. It was shown that the ISPR-catalyzed PSSQ forms a dense and uniform interfacial passivation layer sited tightly on top of metal surface and beneath the polymer layer. A 400 nm thick interfacial passivation layer of PSSQ in the nanocoating on AZ91D was shown to pass 360 hours of salt spray test ( 0.5% corrosion area). The current and future development on self-healing of corrosion protection, Li as anodic protection for Mg in LiMg alloys and encapsulation and release of ISPC/PSSQ corrosion inhibitor in nanocontainer has been illustrated. The excellent corrosion protection performance of ISPC/PSSQ nanocoating on AlMg alloys will be discussed.
Substrate binding modelling in barnase (1991)

The mechanism describing the guanine specific hydrolysis by the different microbial endoribonucleases which has been proposed cannot account in barnase (B. amyloliquefaciens) in the case of GpN dinucleotide hydrolysis, the observed preference for N being A≳G≳C≳U. Similarly the much higher activity toward long RNA molecules as compared to dinucleotides is not understood. A possible explanation for these observations is the existence in barnase of secondary substrate binding sites.
Chronic crusting, nasal carriage of Staphylococcus aureus and relapse rate in pulmonary Wegener's granulomatosis. (2008)

Wegener's granulomatosis is a systemic disease characterized by necrotizing granulomatous inflammation of the upper and lower respiratory tract and necrotizing crescentic glomerulonephritis. Nasal carriage of S. aureus is considered a risk factor for S. aureus infections. The aim was to examine possible risk factors for relapse including refractory nasal carriage of Staphylococcus aureus in patients with Wegener's granulomatosis. Swab cultures from anterior nares for S. aureus were taken in consecutive patients (n=28), with limited (n=15) and systemic forms (n=13) of biopsy-proven Wegener's granulomatosis. The occurrence of infection and relapses were identified according to defined criteria. Seventeen of the 28 patients (60%: 95% Cl, 41-76%) were found to be chronic nasal carriers of S. aureus (> or =80% of nasal cultures positive for S. aureus). A hazard regression analysis identified chronic nasal carriage of S. aureus as independent risk factor for relapse (HR-4.56; Cl 2.45-7.65) in patients with limited Wegener's granulomatosis. Chronic nasal carriage of S. aureus characterized patients with Wegener's granulomatosis, who are more prone to relapses.
Sewers as a Source and Sink of Chlorinated‐Solvent Groundwater Contamination, Marine Corps Recruit Depot, Parris Island, South Carolina (2011)

Groundwater contamination by tetrachloroethene and its dechlorination products is present in two partially intermingled plumes in the surficial aquifer near a former dry‐cleaning facility at Site 45, Marine Corps Recruit Depot, Parris Island, South Carolina. The northern plume originates from the vicinity of former above‐ground storage tanks. Free‐phase tetrachloroethene from activities in this area entered the groundwater. The southern plume originates at a nearby, new dry‐cleaning facility, but probably was the result of contamination released to the aquifer from a leaking sanitary sewer line from the former dry‐cleaning facility. Discharge of dissolved groundwater contamination is primarily to leaking storm sewers below the water table. The strong influence of sanitary sewers on source distribution and of storm sewers on plume orientation and discharge at this site indicates that groundwater‐contamination investigators should consider the potential influence of sewer systems at their sites.
Distributed systems management in wide area networks (1984)

While quite a few distributed operating systems for local-area networks exist, hardly any work has been done to date on distributed operating systems for wide-area networks. In Europe, a number of public networks are now operational, with gateways between some of them. However, the use of these networks is still mostly restricted to "remote login" and, in some cases, simple file transfer operations. To study these problems and to find structural solutions for efficient and simple use of national and international networks the working group "Distributed Systems Management" was founded within COST 11. Recently, this working group has submitted a research proposal to COST 11 to realise an infrastructure for the implementation of distributed services in a wide-area network in a European collaborative effort. The model, underlying the reserach is the service model, used in many local-area network distributed operating systems. The research project is described, and the proposed infrastructure is discussed in some detail.

<title>Synchronization of chaos using proportional feedback</title> (1993)

We have demonstrated experimentally a proportional feedback algorithm for the synchronization of chaotic time signals generated from a pair of independent diode resonator circuits. Synchronization was easily obtained and occurred for relative feedback levels between three and eight percent of the driving voltage. Once established, the synchronization persisted throughout the whole range of the resonator bifurcation diagram without varying the gain of the feedback.
Optimize path planning of a planar parallel robot to avoid obstacle collision using genetic algorithm (2014)

In this paper a new approach to optimize the path of a 3-RRR planar robot is studied. A reforming polynomial is utilized to refine the path of robot when robot faces an obstacle on its way. A genetic algorithm optimization process is used to denote the end-effector position at any time. In this method design of a continuous and smooth motion was noticed, so the actuators remain healthy. Also some examples are presented to exhibit the performance of the proposed approach.

Agents that physiologically activate platelets in vivo include adenosine diphosphate (ADP), epinephrine, collagen, thromboxane A2 (TxA2) and serotonin. Vascular and platelet dysfunction represent complications of hepatic disease. The purpose of this study is to investigate the effect of various agonists on platelet aggregation profile of patient with hepatic disease.
Improved reference genome for the domestic horse increases assembly contiguity and composition (2018)

Recent advances in genomic sequencing technology and computational assembly methods have allowed scientists to improve reference genome assemblies in terms of contiguity and composition. EquCab2, a reference genome for the domestic horse, was released in 2007. Although of equal or better quality compared to other first-generation Sanger assemblies, it had many of the shortcomings common to them. In 2014, the equine genomics research community began a project to improve the reference sequence for the horse, building upon the solid foundation of EquCab2 and incorporating new short-read data, long-read data, and proximity ligation data. Here, we present EquCab3. The count of non-N bases in the incorporated chromosomes is improved from 2.33 Gb in EquCab2 to 2.41 Gb in EquCab3. Contiguity has also been improved nearly 40-fold with a contig N50 of 4.5 Mb and scaffold contiguity enhanced to where all but one of the 32 chromosomes is comprised of a single scaffold.
The Structure of Hexane Soot II: Extraction Studies (1985)

Successive extraction of soluble components of hexane soot with a suite of solvents has been followed by CGC/MS, FT-IR, UV/Vis, fluorescence, and NMR spectroscopic analysis of these extracts. From these studies, additional understanding of the structure and reactivity of this material has emerged. A significant portion of the soot is extractable as polynuclear aromatic and aliphatic compounds, while the nonextractable solid structure, with both aromatic and aliphatic portions, contains such carbon-oxygen functionalities as acid anhydride, carbonyl, and ether linkages. A model of hexane soot as formed in flame is proposed on the basis of this work.
Abstract 2328: Targeting angiogenesis: Anti-docking site peptides to Met receptor and nanotechnology (2012)

Abstract The Met tyrosine kinase receptor is involved in different cell responses during development and pathological conditions. In cancer, Met can promote growth, invasion, angiogenesis and tumor metastasis following the interaction with its ligand, the hepatocyte growth factor (HGF). We decided to develop angiogenesis inhibitors that target the HGF pathway, impairing tumour neo-vascularization and metastatic spreading. We investigated the anti-angiogenic proprieties of a synthetic peptide mimicking the intracellular Met-tail, which was delivered into cells by fusion with the internalization sequences from Antennapedia or HIV-Tat. We are also trying to do peptide delivery by using carbon nanotubes. In order to evaluate the effect of Met-derived inhibitors on angiogenesis, we treated HUVEC with peptides and we evaluated their ability to interfere with HGF-induced proliferation, migration and morphogenesis of endothelial cells in vitro and angiogenesis. Kaposi's sarcoma (KS), the most frequent neoplasia in patients with AIDS, which originates from endothelial origin and is highly vascularized, shows features compatible with the biological properties of HGF. We used KS as tumour model to test the effect of peptides on tumour growth in vivo. We found that the peptides inhibited ligand-dependent endothelial cell proliferation, migration and morphogenesis in vitro and interfered with HGF-dependent downstream signalling. In vivo, the peptides inhibited HGF-induced angiogenesis and Kaposi's sarcoma tumour growth. We also demonstrated that diacylglycerol kinases (DGK) contribute to the malignant phenotype of KS. The data obtained show that the peptides impair angiogenesis triggered by HGF, suggesting the use of anti-docking site compounds as therapeutic agents to interfere with the angiogenesis process. The development of angiogenesis inhibitors and the identification of new intracellular transducers effective in the high vascularised KS cells, open the possibility of a combination therapy that concomitantly interferes with tumour neo-vascularization and the malignant properties of KS.

On the geometry of stabilizer states (2014)

Large-scale quantum computation is likely to require massive quantum error correction (QEC). QEC codes and circuits are described via the stabilizer formalism, which represents stabilizer states by keeping track of the operators that preserve them. Such states are obtained by {\em stabilizer circuits} (consisting of CNOT, Hadamard and Phase gates) and can be represented compactly on conventional computers using $\Theta (n^2)$ bits, where $n$ is the number of qubits \cite{Gottes98}. As an additional application, the work in~\cite{Aaron, AaronGottes} suggests the use of superpositions of stabilizer states to represent arbitrary quantum states. To aid in such applications and improve our understanding of stabilizer states, we characterize and count nearest-neighbor stabilizer states, quantify the distribution of angles between pairs of stabilizer states, study succinct stabilizer superpositions and stabilizer bivectors, explore the approximation of non-stabilizer states by single stabilizer states and short linear combinations of stabilizer states, develop an improved inner-product computation for stabilizer states via synthesis of compact canonical stabilizer circuits, propose an orthogonalization procedure for stabilizer states, and evaluate several of these algorithms empirically.

Effect of Manganese Oxide on the Sintered Properties of 8YSZ (2011)

Abstract The sinterablility of 8 wt. % yttria-stabilized-zirconia (8YSZ) containing different weight ratios of MnO2 as sintering aid was investigated over the temperature range of 1200-1400 °C Relative density, microstructure, microhardness and bending strength as a function of sintering temperature and sintering aid content were investigated. The experiment results show that the addition of MnO2 is effective in aiding densification, and the relative density, microhardness and bending strength of doped samples are generally much higher than those of the undoped samples; the relative density, grain size and microhardness increase with the increasing of sintering temperature and addition content of MnO2; when the additive content of MnO2 is below 3 wt. %, the bending strength increases with the increasing of sintering temperature and addition content of MnO2, sintered at 1300 °Cwith 3 wt. % MnO2 addition, the sample has the maximum bending strength 235.5 MPa, fine grain size and high relative density are two main reasons of the high bending strength and hardness of the materials.

Influence of Magnetic Field on the Mechanical Properties of Austempered Ductile Iron (ADI) (2007)

A novel concept of two-step austempering in a magnetic field has been conceived by this investigator. This twostep process involves first quenching the alloy to a lower temperature after austenitizing and then immediately rising the temperature of the quenching media to a higher temperature and the whole austempering process is carried out in the presence of a high magnetic field. In this investigation, Austempered Ductile Iron (ADI) was processed by this novel two-step austempering process in a high magnetic field of 20 Tesla. The microstructure and the mechanical properties of the ADI processed in a magnetic field has been characterized and compared with ADI processed by conventional process. The results of this investigation indicate significant improvement in the mechanical properties of ADI when Austempered in a high magnetic field. Both yield and tensile strengths were higher in the samples processed in the presence of a magnetic field. Very fine grain ferrite and austenite was obtained in the microstructure. The ferrite content was also significantly higher.
A fully depleted lean-channel transistor (DELTA)-a novel vertical ultrathin SOI MOSFET (1990)

A fully depleted lean-channel transistor (DELTA) that has a gate with a vertical ultrathin SOI structure is reported. In the deep submicrometer region, selective oxidation is useful in realizing SOI isolation. It provides high crystalline quality, as good as that of conventional bulk single-crystal devices. Using experiments and three-dimensional simulation, it was shown that the gate structure has effective channel controllability and its vertical ultrathin SOI structure provides superior device characteristics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
