Enhanced magnetoresistance in naturally oxidized MgO-based magnetic tunnel junctions with ferromagnetic CoFe/CoFeB bilayers (2011)

Three-dimensional elemental distributions in magnetic tunnel junctions containing naturally oxidized MgO tunnel barriers are characterized using atom-probe tomography. Replacing the CoFeB free layer (reference layer) with a CoFe/CoFeB (CoFeB/CoFe) bilayer increases the magnetoresistance from 105% to 192% and decreases the resistance-area product from 14.5 to 3.4 Ω μm2. The CoFe/CoFeB bilayer improves the compositional uniformity within the free layer by nucleating CoFeB crystals across the entire layer, resulting in a homogeneous barrier/free layer interface. In contrast, the simple CoFeB free layer partially crystallizes with composition differences from grain to grain (5–30 nm), degrading the tunnel junction performance.
TURBULENT MIXING (2005)

▪ Abstract The ability of turbulent flows to effectively mix entrained fluids to a molecular scale is a vital part of the dynamics of such flows, with wide-ranging consequences in nature and engineering. It is a considerable experimental, theoretical, modeling, and computational challenge to capture and represent turbulent mixing which, for high Reynolds number (Re) flows, occurs across a spectrum of scales of considerable span. This consideration alone places high-Re mixing phenomena beyond the reach of direct simulation, especially in high Schmidt number fluids, such as water, in which species diffusion scales are one and a half orders of magnitude smaller than the smallest flow scales. The discussion below attempts to provide an overview of turbulent mixing; the attendant experimental, theoretical, and computational challenges; and suggests possible future directions for progress in this important field.
Generalized methodology for modeling and simulating optical interconnection networks using diffraction analysis (1995)

Research in the field of free-space optical interconnection networks has reached a point where simulators and other design tools are desirable for reducing development costs and for improving design time. Previously proposed methodologies have only been applicable to simple systems. Our goal was to develop a simulation methodology capable of evaluating the performance characteristics for a variety of different free-space networks under a range of different configurations and operating states. The proposed methodology operates by first establishing the optical signal powers at various locations in the network. These powers are developed through the simulation by diffraction analysis of the light propagation through the network. After this evaluation, characteristics such as bit-error rate, signal-to-noise ratio, and system bandwidth are calculated. Further, the simultaneous evaluation of this process for a set of component misalignments provides a measure of the alignment tolerance of a design. We discuss this simulation process in detail as well as provide models for different optical interconnection network components.
Automated Parallel, Multi-Step Polymer-Assisted Solution Phase (PASP) Synthesis of Substituted Benzimidazole Derivatives (2004)

The automated polymer-assisted solution phase (PASP) synthesis of a 72 member library of 2-alkylthio-benzimidazoles 16 and benzimidazolin-2-ones 17 using commercially available robotic workstations is described. By incorporating both automated aqueous work-ups, in-line scavenging and 'catch and release' protocols the desired compounds were obtained directly in good yields and excellent purities without the need for conventional chromatographic purification. The synthesis described demonstrates how both manual and automated equipment may be utilised together to provide a versatile approach that facilitates parallel compound synthesis.
High Serum IgG4 Concentrations in Patients with Sclerosing Pancreatitis (2001)

Patients with sclerosing pancreatitis have high serum IgG4 concentrations, providing a useful means of distinguishing this disorder from other diseases of the pancreas or biliary tract.
Three-dimensional numerical modelling of discontinuous fibre composite architectures (2011)

A three-dimensional geometrical model is presented for generating discontinuous random fibre architectures consisting of high filament count bundles. The fibre network model randomly distributes fibre bundles in a three-dimensional volume using a non-contact algorithm, together with Catmull–Rom spline interpolation, to provide a physically representative material. Only the spines of the fibre bundles are modelled, using truss elements to permit high fibre volume fractions of up to 60%, with no restriction on the fibre bundle aspect ratio. ABAQUS/Standard is used to predict the tensile performance for coupons with varying levels of out-of-plane fibre curvature. The effect of fibre curvature was found to be insignificant for tensile modulus, but a 34% reduction in ultimate tensile strength (UTS) was observed when adjusting the maximum permissible out-of-plane angle of fibres from 1 to 35°. A novel method for characterising the degree of out-of-plane fibre curvature within experimental test coupons is also discussed.
New wideband microstrip antenna using log-periodic technique (1980)

A novel wideband microstrip antenna using a series-fed linear array of patch resonators in a log-periodic arrangement is described. A 9-element example gives good input v.s.w.r. and radiation control over a 30% bandwidth with better than 70% efficiency. The new array configuration gives wider bandwidth than single-layer or stacked microstrip patches combined with better efficiency than patches on lossy substrates or microstrip spirals.

Progression of Vision Loss in Macular Telangiectasia Type 2 (2015)

A characteristic feature in patients with MacTel type 2 is progressive focal loss of macular sensitivity, preceding loss of visual acuity. Microperimetry is sensitive to detect such functional decline and thus may provide considerable power when being used as a functional outcome measure in future clinical trials.

Pharmacomanometric Studies of Colonic Motility as a Guide to the Chemotherapy of Schizophrenia (1980)

Distal colon motility studies performed in 41 psychotic subjects demonstrated that 32 of them had hyperactivity of the noradrenergic system at this peripheral level, while the remaining nine cases showed hyperactivity of the dopaminergic system. The noradrenergic-hyperactive patients fulfilled the Research Diagnostic Criteria of schizophrenia, whereas the dopaminergic-hyperactive patients were diagnosed as having schizoaffective disorders. Noradrenergic-hyperactive subjects were successfully treated with clonidine, a drug which inhibits release of noradrenaline, while dopaminergic-hyperactive subjects were successfully treated with clonazepam, a drug which inhibits release of dopamine. The addition of sulpiride (a postsynaptic dopaminergic blocking agent) and of phentolamine (a postsynaptic noradrenergic blocking agent) to clonidine and clonazepam, respectively, induced further significant improvements in both types of psychotic patients.
A Novel Modulation with Parallel Combinatory and High Compaction Multi-Carrier Modulation (2007)

In this paper, we propose a new modulation named parallel combinatory/high compaction multi-carrier modulation (PC/HC-MCM) using the techniques of parallel combinatory orthogonal frequency division multiplexing (PC-OFDM) and high compaction multi-carrier modulation (HC-MCM).Two types of PC/HC-MCM systems, which are named as modulated PC/HC-MCM system and (unmodulated) PC/HC-MCM system, can be designed.The modulated PC/HC-MCM system achieves better bit-error rate (BER) performance than that of HC-MCM system with equal bandwidth efficiency (BWE).The PC/HC-MCM system can obtain the better peak-to-average power ratio (PAPR) characteristics by selecting appropriate constellation for each subcarrier.On the other hand, since PC/HC-MCM can divide the PC-OFDM symbol duration into multiple time-slots, the advantages of frequency hopping (FH) can be applied in the PC/HC-MCM system.Therefore, we also combine the PC/HC-MCM and frequency hopping multiple access (FHMA) to propose a novel multiple access (MA) system.It can simultaneously transmit multiple users' data within one symbol duration of PC-OFDM.

Basic Progress and Future Therapeutic Perspectives of Relaxin in Ischemic Heart Disease (2005)

Relaxin has been validated as a cardiotropic hormone, being produced by the heart and acting on specific heart receptors. Evidence is accumulating that it could hamper the pathophysiologic mechanisms of ischemic heart disease. Time is ripe to study relaxin as a cardiotropic drug, as recombinant human relaxin (hrRLX) is now available and previous clinical trials have shown a virtual lack of toxicity and adverse side effects, even at high doses. Our recent observations suggest that relaxin, besides being a preventative agent, may also be effective in the treatment of acute myocardial infarction and may be an adjuvant for precursor cell grafting to repair postinfarct myocardium. In a swine model of myocardial infarction currently used to test cardiotropic drugs due to its similarities with human ischemic heart disease, hrRLX, given at reperfusion upon 30 min of ischemia, markedly reduced serum and tissue markers of myocardial injury, cardiomyocyte apoptosis and leukocyte recruitment, resulting in overall improvement in cardiac performance compared with the controls. In in vitro mixed cultures of mouse skeletal myoblasts and adult rat cardiomyocytes, relaxin increased gap junction formation and potentiated gap junction-mediated intercellular exchanges and signaling between the coupled cells. In view of the therapeutic use of myoblast grafting for cardiac repair, relaxin could hence favor the electromechanical coupling of grafted myoblasts with the resident cardiomyocytes and facilitate their transdifferentiation towards a cardiac phenotype. Relaxin, therefore, shows promising therapeutic potential in cardiology and cardiac surgery.
[Study on the salivary adenoid cystic carcinoma with the flow cytometric analysis]. (1993)

The cellular DNA content of 28 cases of salivary adenoid cystic carcinoma (SACC) were quantified with the flow cytometric analysis. The result showed that majority of SACC (22/28) were diploidy tumors. No significant correlation between the cellular DNA content and the histopathologic appearances, the cellular DNA content and the clinical behavior of SACC was found.
Contribution of the individual components of the Î´-endotoxin crystal to the mosquitocidal activity of<i>Bacillus thuringiensis</i>subsp.<i>israelensis</i> (1995)

The δ-endotoxin crystal of the mosquitocidal bacterium Bacillus thuringiensis subsp. israelensis contains four major 0-endotoxins. Expression systems were devised to synthesize each of the four toxins at concentrations at which they formed inclusion bodies in an acrystalliferous mutant of Bacillus thuringiensis. The relative activities of these inclusions were then determined against Aedes aegypti larvae. Bioassays of mixtures of the individual toxins revealed a number of synergistic interactions which explained in part why the native crystal is considerably more toxic than any of the individual toxins.
New coating materials prepared by radiation‐induced polymerization. I. Mar‐resistant coating composition and properties (1978)

Abstract A mar‐resistant coating system was obtained by screening combinations of silicone and vinyl compounds. It was found that binary systems, such as the γ‐glycidoxypropyltrimethoxysilane–glycidyl methacrylate system, were excellent not only in mar resistance but also in adhesion to base resin polymers. Haze values of these coatings, after the sand‐falling test, reached less than 10%. The coating process consisted of three steps: the preparation of prepolymer, the coating to plastic surface, and the curing of the coating by heating. It was found that the prepolymerization step could be performed by irradiation very conveniently; the control of viscosity for coating application and thickness control could be possible without any gel formation. These coatings were also good in weather resistance due perhaps to the good adhesion to base resin and could be applicable to plastic spectacles, glazing materials, and a variety of other products.
Coriolis contribution to the rotatory ether drag (1979)

Abstract The theory of the rotatory ether drag recently discovered by Jones is discussed. It is shown that the existing theories did not take into account the Coriolis force influencing the electron motion. The Coriolis contribution to the rotatory ether drag coefficient is expressed via the Faraday effect constant. The absolute value of the Coriolis term is found to be approximately equal to the dispersion term and to have the opposite sign.
Engineering of Self‐Propelling Microbots and Microdevices Powered by Magnetic and Electric Fields (2017)

Abstract In the last two decades, advances in micro‐ and nanofabrication have enabled the development of a wide variety of active or “self‐propelling” microparticles, which convert energy from their environment into directed motion. While these autonomous entities have shown promise for efficient locomotion on the microscale, their practical utility remains unrealized due to their inability to perform multiple useful tasks on demand. From an engineering perspective, the active particle behavior can be encoded on an individual level by tailoring key design elements such as shape, polarizability, surface pattern, and bulk functionality. This feature article focusses on active particles powered by electric and magnetic fields, as these sources of energy allow the particles to: (1) move in several phenomenologically unique ways, (2) respond in a reliable manner to the field parameters, and (3) interact synergistically to enable multiple functions. It is hypothesized how future generations of such particles may remotely harvest and transduce energy to perform several useful tasks such as biosensing and delivering drugs. As a step toward realizing such particles, several new types of active particles are demonstrated. Finally, a perspective on the future directions of this emerging field is provided by discussing current challenges, potential applications as well as future opportunities.
Discovery of S-Phase Arresting Agents Derived from Noscapine (2005)

Analogues of the natural product noscapine were synthesized, and their potential as antitumor agents were examined. The discovery of a novel regio- and stereoselective O-demethylation led to the synthesis of several O-alkylated analogues that induced an unexpected S-phase arrest of mammalian cells. Compound 4a was the most potent analogue inhibiting cell proliferation at an EC(50) of 1.9 microM.
User Scheduling for Network MIMO Systems with Successive Zero-Forcing Precoding (2010)

In this paper we consider simplified greedy user scheduling algorithms for clustered network multiuser multiple-input multiple-output (MIMO) systems with successive zero-forcing (SZF) precoding. The optimal user scheduling involves an exhaustive search, which is very complex. Among various suboptimal but lower complexity algorithms, greedy algorithms with heuristic scheduling metrics have been shown to achieve performance close to the exhaustive search. In this paper, we propose two simplified algorithms: interference-aware greedy user scheduling (IA-GUS) and interference-whitening greedy user scheduling (IW-GUS). IA-GUS schedules the users based on the information on interference power of the selected users in surrounding cooperating clusters, and IW-GUS schedules the users based on the information on whitened channels of all users requesting the service in the cluster. IA-GUS has lower complexity and performs better than IW- GUS. Simplified metrics for proportionally fair (PF) scheduling are also proposed. Performance of the proposed algorithms is analyzed and compared with dirty paper coding (DPC), block diagonalization (BD) and systems without network coordination. Simulation results demonstrate that the proposed algorithms for SZF achieve much higher outage capacity compared to BD with previously proposed algorithms.
Content-Aware Collaborative Filtering for Location Recommendation Based on Human Mobility Data (2015)

Location recommendation plays an essential role in helping people find places they are likely to enjoy. Though some recent research has studied how to recommend locations with the presence of social network and geographical information, few of them addressed the cold-start problem, specifically, recommending locations for new users. Because the visits to locations are often shared on social networks, rich semantics (e.g., tweets) that reveal a person's interests can be leveraged to tackle this challenge. A typical way is to feed them into traditional explicit-feedback content-aware recommendation methods (e.g., LibFM). As a user's negative preferences are not explicitly observable in most human mobility data, these methods need draw negative samples for better learning performance. However, prior studies have empirically shown that sampling-based methods don't perform as well as a method that considers all unvisited locations as negative but assigns them a lower confidence. To this end, we propose an Implicit-feedback based Content-aware Collaborative Filtering (ICCF) framework to incorporate semantic content and steer clear of negative sampling. For efficient parameter learning, we develop a scalable optimization algorithm, scaling linearly with the data size and the feature size. Furthermore, we offer a good explanation to ICCF, such that the semantic content is actually used to refine user similarity based on mobility. Finally, we evaluate ICCF with a large-scale LBSN dataset where users have profiles and text content. The results show that ICCF outperforms LibFM of the best configuration, and that user profiles and text content are not only effective at improving recommendation but also helpful for coping with the cold-start problem.
Neurospora crassa suppressors act on amber (1984)

The nonsense mutant am l7 , is suppressible by ssu-1 by tyrosine insertion in residue 313 of NADP -Neurospora crassa suppressors act on amber. specific glutamate dehydrogenase. It can revert to either Leu 313 or Tyr 313 , consistent with the nonsense codon being either amber (UAG) or ochre (UAA) (Seale et al., 1976 Genetics 86: 261-274). DNA sequencing of the wild type gene (Kinnaird and Fincham, 1983 Gene 26 : 253-260) shows codon 313 to be CAG (glutamine). Furthermore, we find that am 17 is induced to revert with-nitroquinoline oxide (NQO), a mutagen reported to be specific for G-C base paires (Prakash et al., 1974 J. Mol. Biol. 85: 51-65). We conclude that the nonsense codon,in am 17 is amber (UAG). Since known Neurospora supersuppressors all suppress the same set of mutants (Seale, 1976 MGG 148: 105-108) they must all suppress amber. There is no evidence as yet for ochre-or UGA-suppressing mutations in Neurospora. Given the very selective codon usage found so far in strongly and constitutively transcribed Neurospora genes (reviewed in Kinnaird and Fincham, 1983), UAA and UGA nonsense mutants would in any case be expected to be much less frequent than UAG in such genes. With no condons with A in the 3' position , only tyrosine (UAE) can mutate by single base-pair substitution to UAA and only tryptophan (UGG) or cysteine (UG~) to UGA; UAG, on the other hand, can arise from the abundant glutamate (GAG), glutamine (CAG) and lysine (AAG) codons.
