Domain structure of a mammalian myosin I beta. (1994)

We have determined the primary structure of a myosin I (called mammalian myosin I beta, MMI beta) from bovine brain and identified its functional domains. The protein was previously purified from brain and adrenal gland. Several constructs were generated and expressed in Escherichia coli as glutathione S-transferase fusion proteins and the recombinant proteins were recognized by monoclonal antibodies that recognize either "head" or "tail" domains of native myosin I. A gel overlay method was used to confirm that calmodulin binds to the consensus calmodulin-binding sequence in MMI beta. Binding assays were used to detect interaction with anionic phospholipid vesicles. We conclude that MMI beta consists of an amino-terminal 80.5-kDa domain that contains the ATP- and actin-binding sites, followed by an 8.5-kDa domain with three calmodulin-binding sequences and a basic 30-kDa carboxyl-terminal tail segment that binds to anionic phospholipids and membranes.
Atomic View of Surface Self-Diffusion: Tungsten on Tungsten (1966)

Surface diffusion of tungsten adatoms on several smooth, low-index planes of the tungsten lattice has for the first time been followed by direct observation of individual atoms in the field-ion microscope. Contrary to expectation, the mobility at room temperature is found to increase in the order (211) &gt; (321) ∼ (110) &gt; (310) ∼ (111). Migrating atoms are reflected at the boundaries of the (110), (211), and (321) planes; on the latter two, motion along atomic rows is favored over diffusion across lattice steps. From quantitative determinations of the rate of change of the mean-square displacement, diffusion coefficients are obtained as follows: (110), D=3×10−2exp(−22 000/RT)cm2/sec; (321), 1×10−3exp(−20 000/RT); (211), 2×10−7exp(−13 000/RT). Differences in diffusion on the (211) and (321), planes of very similar structure, suggest a weakening of interatomic forces at lattice edges.

Stress induced magnetization changes of steel pipes--Laboratory tests (1983)

Magnetometer surveys above gas pipelines show stress induced magnetic anomalies at pipe bends. This suggests a potential technique for the noninvasive monitoring of stress in buried pipelines, etc. Laboratory measurements of the magnetic field changes due to the elastic bending of 110 mm diameter pipe are presented. The effects of orientation with respect to the earths field and of internal pressure are reported. Hysteretic effects are found to be important.
A Helical Conotoxin from Conus imperialis Has a Novel Cysteine Framework and Defines a New Superfamily (2012)

Cone snail venoms are a rich source of peptides, many of which are potent and selective modulators of ion channels and receptors. Here we report the isolation and characterization of two novel conotoxins from the venom of Conus imperialis. These two toxins contain a novel cysteine framework, C-C-C-CC-C, which has not been found in other conotoxins described to date. We name it framework XXIII and designate the two toxins im23a and im23b; cDNAs of these toxins exhibit a novel signal peptide sequence, which defines a new K-superfamily. The disulfide connectivity of im23a has been mapped by chemical mapping of partially reduced intermediates and by NMR structure calculations, both of which establish a I-II, III-IV, V-VI pattern of disulfide bridges. This pattern was also confirmed by synthesis of im23a with orthogonal protection of individual cysteine residues. The solution structure of im23a reveals that im23a adopts a novel helical hairpin fold. A cluster of acidic residues on the surface of the molecule is able to bind calcium. The biological activity of the native and recombinant peptides was tested by injection into mice intracranially and intravenously to assess the effects on the central and peripheral nervous systems, respectively. Intracranial injection of im23a or im23b into mice induced excitatory symptoms; however, the biological target of these new toxins has yet to be identified.
Crystallization kinetics of sputter-deposited amorphous AgInSbTe films (2001)

AgInSbTe films have recently attracted considerable interest as advanced materials for phase change recording. For this application the determination of crystallization kinetics is of crucial importance. In this work the temperature dependence of structural and electrical properties of sputtered AgInSbTe films has been determined. Temperature dependent measurements of the electrical resistance have been employed to study the kinetics of structural changes of these films. Upon annealing a major resistivity drop is observed at around 160 °C which can be attributed to a structural change as corroborated by x-ray diffraction. X-ray diffraction shows an amorphous phase for as-deposited films, while crystalline films with hexagonal structure (a=4283 Å, c=16 995 Å) are obtained upon annealing above 160 °C. By applying Kissinger’s method, an activation energy of 3.03±0.17 eV is obtained for the crystallization. X-ray reflection measurements reveal a density increase of 5.2%±0.2% and a thickness decrease of 5.5%±0.2% upon crystallization.
Citrinolactones A, B and C, and Sclerotinin C, Plant Growth Regulators from<i>Penicillium citrinum</i> (2007)

New plant growth regulators, named citrinolactones A (1), B (2) and C (3) and sclerotinin C (4), were isolated from Penicillium citrinum and their structures established by spectroscopic methods including 2D NMR. Compounds 1 and 4 increased root growth in proportion to their concentration from 3 to 300 mg/l. In contrast, 2 completely inhibited root growth at a concentration of 300 mg/l and 3 did not show any effect on root growth in a concentration range of 3-300 mg/l.

A parametric study of fault mechanical changes associated with geological sequestration of carbon dioxide (2005)

In this paper, a geomechanical model is proposed to study the influence of CO2 (carbon dioxide) geological sequestration on the mechanical changes of faults around the injection well by the finite element simulation. Through the numerical parametric studies, such as the thickness and spread width of CO2 plume, the injection pressure, the depth of injection well and the caprock permeability, effects of the injection pressure and the buoyancy of CO2plume on the mechanical changes of faults are clearly interpreted. The study shows that the shear stress change along the fault surface is sensitive to the variation of the injection pressure, the thickness and spread width of CO2plume. The relative slip displacement of fault surfaces is significantly small in current studies. Finally, some suggesting remarks are concluded to decide ideal geological disposal sites for CO2 sequestration.
Image Coding With Geometric Wavelets (2006)

This paper describes a new and efficient method for low bit-rate image coding which is based on recent development in the theory of multivariate nonlinear piecewise polynomial approximation. It combines a binary space partition scheme with geometric wavelet (GW) tree approximation so as to efficiently capture curve singularities and provide a sparse representation of the image. The GW method successfully competes with state-of-the-art wavelet methods such as the EZW, SPIHT, and EBCOT algorithms. We report a gain of about 0.4 dB over the SPIHT and EBCOT algorithms at the bit-rate 0.0625 bits-per-pixels (bpp). It also outperforms other recent methods that are based on "sparse geometric representation." For example, we report a gain of 0.27 dB over the Bandelets algorithm at 0.1 bpp. Although the algorithm is computationally intensive, its time complexity can be significantely reduced by collecting a "global" GW n-term approximation to the image from a collection of GW trees, each constructed separately over tiles of the image.
Banyan networks for partitioning multiprocessor systems (1998)

This paper describes a class of partitioning networks, called banyans, whose cost function grows more slowly than that of the crossbar and whose fan-out requirements are independent of network size. Such networks can economically partition the resources of large modular systems into a wide variety of subsystems. Any possible partition can be realized by paralleling several networks or by multiplexing a single network in a manner to be described later. Results will be given indicating that a cost/performance advantage over the crossbar can be obtained for large systems and that the crossbar can, in fact, be considered a non-optimal special case of a banyan network. Inherent fail-soft capability and the existence of rapid control algorithms which can be largely performed by distributed logic within the network are also important attributes of banyans. This paper presents fundamental properties and preliminary simulation results of banyan partitioning networks. A more detailed treatment, including proofs of theoretical properties, is reserved for reference (5).
LED조명의 조도 및 휘도가 감성과 작업능률에 미치는 영향 (2016)

The criteria on evaluation of human sensitivity and sensitivity items themselves related to LED lighting are not established. Thus the evaluation of color temperature and color rendition based on user's sensitivity as well as appropriate sensitivity criteria are necessary. Because recently human sensitivity is emphasized, lighting plays an important role providing visual sensation and a diversity of experiences associated with thought, association, and sensitivity. This study aims at the development of space evaluation index while constructing appropriate lighting environment conforming functional requirements of office, analyzing optical characteristics of LED lighting, and understanding users' preferences related to emotional characteristics and visual fatigue.

Structural design considerations are described as well as the experimental results. It is shown that the proposed WLP SAW filters are suitable for the applications to RF front-end modules which are transfer molded with ICs.
Design of Broadband Highly Efficient Harmonic-Tuned Power Amplifier Using In-Band Continuous Class-${\hbox{F}}^{-1}/{\hbox{F}}$ Mode Transferring (2012)

A novel methodology for designing high-frequency broadband harmonic-tuned power amplifiers (PAs) is presented in this paper. Specifically, a hybrid PA mode, transferring between continuous inverse Class-F and continuous Class-F, is for the first time employed to design PAs with optimal performance over more than-an-octave bandwidth. A GaN PA is designed and realized based on this mode-transferring operation using a three-stage transmission-line-based low-pass matching network. Simulation and experimental results show that an in-band PA-mode transferring between continuous Class- F <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> and continuous Class-F is successfully performed. The implemented PA achieves a measured 87% bandwidth from 1.3 to 3.3 GHz, while exhibiting a state-of-the-art performance of >;10-dB gain, 60%-84% efficiency, and 10-W output power throughout this band. Furthermore, modulated evaluation is carried out using a 300-kHz bandwidth 16-quadrature amplitude-modulation signal. Good linearity performance is measured with adjacent channel power ratio from -20 to -35 dBc and an error vector magnitude of 4%-9% over the entire bandwidth.
Buried Mask Revelation in Silicon Dioxide for Double Gate MOS Fabrication (2006)

A new process for self-aligned double gate MOS fabrication is proposed. The milestone of this process in the revelation of a buried mask in the BOX of a SOI wafer and in a thermal oxide layer on top of active silicon film. The revelation of the buried mask makes use of the highly selective etching of implanted oxide in VHF. The etching mechanism of VHF etching of oxide is presented and the influence of the VHF etching parameters like temperature and etching time are discussed to prove the feasibility of this process step in order to integrate it in the whole process
The Motion of Planar, Compliantly Connected Rigid Bodies in Contact, With Applications to Automatic Fastening (1993)

We consider the problem of planning and predicting the mo tion of a flexible object amid obstacles in the plane. We model the flexible object as a rigid "root" body attached to compli ant members by torsional springs. The root's position may be controlled, but the compliant members move in response to forces from contact with the environment. Such a model en compasses several important and complicated mechanisms in mechanical design and automated assembly: snap-fasteners, latches, ratchet-and-pawl mechanisms, and escapements. The problem is to predict the motion of such a mechanism amid fixed obstacles. For example, our algorithm could be used to determine whether a snap-fastener design can be assembled with a certain plan. In this article we analyze the physics of these flexible de vices and develop combinatorially precise algorithms for predicting their movement under a motion plan. Our algo rithms determine when and where the motion will terminate and also compute the time history of contacts and mating forces. In addition to providing the first known exact algorithm that addresses flexibility in motion planning, we also note that our approach to compliance permits an exact algorithm for predicting motions under rotational compliance, which was not possible in earlier work. We discuss the following issues: the relevance of our ap proach to engineering (which we illustrate through examples we ran using our system), the computational methods em ployed, the algebraic techniques for predicting motions in contact with rotational compliance, and issues of robustness and stability of our geometric and algebraic algorithms. Our computational viewpoint lies in the interface between differen tial theories of mechanics and combinatorial collision detection algorithms. From this viewpoint, subtle mathematical difficul ties arise in predicting motions under rotational compliance, such as the forced nongenericity of the intersection problems encountered in configuration space. We discuss these problems and their solutions. Finally, we extend our work to predict the forces on the manipulated objects as a function of time and show how our algorithm can easily be extended to include uncertainty in control and initial conditions. With these extensions, we hope that our system could be used to analyze and design objects that are easy to assemble, even given control and sensing errors, and that require more force to disassemble than to mate.
Design, Synthesis, and Characterization of a Persistent Nonacene Derivative (2010)

A significant technical barrier (i.e., facile oxidative degradation) that has prevented the preparation of large acenes has now been breached. Using a combination of experimentally and theoretically derived substituent effects, the design, synthesis, isolation, and characterization of the first persistent nonacene derivative is described. The molecular design strategy includes placement of arylthio (or alkylthio) substituents on the terminal rings of the nonacene skeleton, effectively converting an open-shell singlet diradical into a closed-shell system. These powerful substituent effects appear to be suitable for the synthesis of other persistent, soluble, large acene derivatives required for advanced thin-film organic semiconductor applications.

Lithium dosing strategies during pregnancy and the postpartum period (2017)

<b>Background</b>Lithium is challenging to dose during pregnancy.<b>Aims</b>To provide guidance for dosing lithium during pregnancy.<b>Method</b>Retrospective observational cohort study. Data on lithium blood level measurements (<i>n</i> = 1101), the daily lithium dose, dosing alterations/frequency and creatinine blood levels were obtained from 113 pregnancies of women receiving lithium treatment during pregnancy and the postpartum period.<b>Results</b>Lithium blood levels decreased in the first trimester (-24%, 95% CI -15 to -35), reached a nadir in the second trimester (-36%, 95% CI -27 to -47), increased in the third trimester (-21%, 95% CI -13 to -30) and were still slightly increased postpartum (+9%, 95% CI +2 to +15). Delivery itself was not associated with an acute change in lithium and creatinine blood levels.<b>Conclusions</b>We recommend close monitoring of lithium blood levels until 34 weeks of pregnancy, then weekly until delivery and twice weekly for the first 2 weeks postpartum. We suggest creatinine blood levels are measured to monitor renal clearance.
Formation of complexes between self-peptides and MHC class II molecules in cells defective for presentation of exogenous protein antigens (1992)

A vertebrate immune response is initiated by the presentation of foreign protein Ag to MHC class II-restricted T lymphocytes by specialized APC. Presentation of self-peptides in association with MHC class II molecules is also necessary for the induction of T cell tolerance. It is important to understand whether functionally divergent APC are responsible for delivering these distinct signals to class II-restricted T cells. Here we examine the ability of I-Ad surface molecules expressed in diverse cell types to stimulate I-Ad-restricted T cells. Recipients included J558L myeloma cells and EL4 lymphoma cells expressing barely detectable or undetectable levels of Ii chain mRNA. This allowed us to examine the influence of Ii expression on the presentation of intracellular Ag and thus test the hypothesis that Ii chain is necessary to prevent access of self-peptides to newly synthesized class II molecules. Ii chain expression did not restore the ability of transformants to process and present soluble protein Ag. A striking result was the finding that cells showing a defect in the exogenous class II presentation pathway were capable of functioning as stimulators when they expressed intracellular secreted but not signal-less V-CH3b Ag. Thus, so-called professional APC that can capture and process exogenous protein Ag may express a specialized set of proteins not required for the presentation of self-peptides.
Energy consumption modeling and optimization for production machines (2008)

In order to facilitate the process of replacing existing energy sources with sustainable alternatives and to minimize the environmental impact, the energy efficiency not only in consumer and building technology, but also in manufacturing has to be improved. At present, no suitable techniques are available to model and optimize the energy consumption behavior of production machines that take into account how the machines are used. To overcome this limitation, we introduce a lean, scalable modeling formalism that allows making predictions about the energy efficiency depending on design and operation. We present examples for modeling and optimization of a milling machine.

Gaussian Interference Networks: Sum Capacity in the Low-Interference Regime and New Outer Bounds on the Capacity Region (2009)

Establishing the capacity region of a Gaussian interference network is an open problem in information theory. Recent progress on this problem has led to the characterization of the capacity region of a general two-user Gaussian interference channel within one bit. In this paper, we develop new, improved outer bounds on the capacity region. Using these bounds, we show that <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">treating</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">interference</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">as</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">noise</i> achieves the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sum</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">capacity</i> of the two-user Gaussian interference channel in a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">low-interference</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">regime</i> , where the interference parameters are below certain thresholds. We then generalize our techniques and results to Gaussian interference networks with more than two users. In particular, we demonstrate that the total interference threshold, below which treating interference as noise achieves the sum capacity, increases with the number of users.
