A nanopass framework for commercial compiler development (2013)

Contemporary compilers must typically handle sophisticated high-level source languages, generate efficient code for multiple hardware architectures and operating systems, and support source-level debugging, profiling, and other program development tools. As a result, compilers tend to be among the most complex of software systems. Nanopass frameworks are designed to help manage this complexity. A nanopass compiler is comprised of many single-task passes with formally defined intermediate languages. The perceived downside of a nanopass compiler is that the extra passes will lead to substantially longer compilation times. To determine whether this is the case, we have created a plug replacement for the commercial Chez Scheme compiler, implemented using an updated nanopass framework, and we have compared the speed of the new compiler and the code it generates against the original compiler for a large set of benchmark programs. This paper describes the updated nanopass framework, the new compiler, and the results of our experiments. The compiler produces faster code than the original, averaging 15-27% depending on architecture and optimization level, due to a more sophisticated but slower register allocator and improvements to several optimizations. Compilation times average well within a factor of two of the original compiler, despite the slower register allocator and the replacement of five passes of the original 10 with over 50 nanopasses.
Crystal Structure of the Cytoskeleton-associated Protein Glycine-rich (CAP-Gly) Domain (2002)

Cytoskeleton-associated proteins (CAPs) are involved in the organization of microtubules and transportation of vesicles and organelles along the cytoskeletal network. A conserved motif, CAP-Gly, has been identified in a number of CAPs, including CLIP-170 and dynactins. The crystal structure of the CAP-Gly domain of Caenorhabditis elegans F53F4.3 protein, solved by single wavelength sulfur-anomalous phasing, revealed a novel protein fold containing three beta-sheets. The most conserved sequence, GKNDG, is located in two consecutive sharp turns on the surface, forming the entrance to a groove. Residues in the groove are highly conserved as measured from the information content of the aligned sequences. The C-terminal tail of another molecule in the crystal is bound in this groove.
EPR power pattern analysis for cubic sites of Fe3+ in MgO (1984)

A complete electron paramagnetic resonance power pattern characterization of Fe3+ in cubic sites in presented. A one-to-one correspondence among the peaks appearing in the powder pattern and the outer fine-structure transitions (M≠ 1/2 ) observed in the single crystal along the 〈100〉, 〈111〉, and 〈110〉 directions is shown. It is shown that the process of mechanically grinding the single crystal to a powder (particle size ∼1–10 μ) does not remove the cubic symmetry sites. No axial or lower symmetry sites which may be induced by lattice distortion of the crystallites due to strain have been observed.
Padé approximant bounds on the positive solutions of some nonlinear elliptic equations (1978)

Synopsis We consider the equation L φ − λ p φ + γ q φ 2 = f on a bounded domain in R n with homogeneous Neumann-Dirichlet boundary conditions. L is a negative definite uniformly elliptic differential operator, while, p , q and f are positive functions. We show that there exists exactly one positive solution for each λ ∈ R and γ > 0. This solution can be analytically continued throughout Re γ > 0: it is a Laplace transform of a positive measure. The measure is bounded prior to the bifurcation point of the associated “homogeneous” equation and unbounded after. Noting that any Laplace transform of positive measure has associated with it a natural sequence of Tchebycheff systems, it now follows that one can obtain monotonically converging upper and lower bounds which are provided by the generalized Padé approximants generated from the Tchebycheff systems.
Interstrand resistance of SSC magnets (1994)

In situ interstrand resistance measurements were conducted on selected section of the inner coil of a full size (15 m) and a short (1 m) model SSC magnets. A model for evaluating single contacts resistance between two strands was developed. Using this model analyses of adjacent and non-adjacent strand contacts were performed. The interstrand resistance distribution throughout the coil was found to correlate with the quench location data as well as with the multipoles decay characteristics of the magnet. An anisotropic continuum based model for evaluation of cable eddy current losses was developed and results were compared with the experimental data.
Short-Wavelength Light Propagation in Graded Photonic Crystals (2011)

Control of electromagnetic fields using graded photonic crystals (GPhCs) is explored using equations of Hamiltonian optics. Contrary to previous works devoted to the long-wavelength regime enabling homogenization of photonic metamaterials, attention is paid to short-wavelength light propagation for the possible use of dispersive phenomena and light path reconfiguring with wavelength. An analytical description of the dispersion diagram of a square PhCs is extracted using plane wave expansion calculations, making possible the description of arbitrary light paths in 2-D GPhC structures and fast optimization to find the conditions suited to make light follow prescribed paths. The validity of the approach is validated by comparison with finite-difference time-domain simulation. For purpose and illustration, a wavelength demultiplexing structure with four channels and an overall surface of 60 μm × 60 μm is proposed. The described methodology is applicable to the generalized 2-D chirp of PhC lattice or filling ratio parameters for electromagnetic field shaping.
Abstract 302: Neuregulin-1β Inhibits TGFβ-induced Cardiofibroblast to Myofibroblast Transition (2013)

Neuregulin (NRG) is a growth and survival factor critical for cardiac development and repair. Our laboratory recently demonstrated decreased fibrosis with NRG treatment in post-infarcted swine. We subsequently hypothesized that NRG inhibits transition of fibroblasts to myofibroblasts (myoFbs), the cells primarily responsible for collagen deposition after cardiac injury. Immunohistochemistry of post-infarcted swine hearts confirmed reduced presence of myoFbs in NRG-treated pig ventricles, compared to untreated animals. Further investigation revealed that NRG acts directly upon primary cultures of rat cardiac fibroblasts, with subsequent phosphorylation of both AKT and p38. Based on quantitative RT-PCR, primary fibroblasts isolated from both rats and mice express ErbB2 and ErbB3, which are known to form heterodimers and thereby transduce the NRG signal. NRG treatment also reduced myoFb percentages by ~40% in primary rat and mouse cardiac cultures, compared to untreated cells, as demonstrated by immunohistochemistry, Western blot, and flow cytometric analyses of the myoFb marker, alpha smooth muscle actin. NRG pre-treatment of cardiac fibroblasts likewise inhibited TGFβ-induced fibroblast-to-myoFb transition, including suppression of SMAD3 phosphorylation and reduction of the down-stream pro-fibrotic proteins, collagen I and periostin. Considered together, these data strongly support the hypothesis that NRG modulates fibroblast signaling directly. These results demonstrate that NRG inhibits the activation of pro-fibrotic cells and suggests a novel mechanism by which NRG treatment might improve cardiac remodeling.
The Effect of the Ultra-Fine Solid Additives on the Mechanical Properties of a Powder Bed [Translated]<sup>†</sup> (1988)

Solid additives are widely used to control the mechanical properties of powders materials in many industries. In this paper, the measurement of the tensile strength of a powder bed with a split-cell type tester was conducted to elucidate the effect of solid additives on the mechanical properties of powders. Fused alumina powder, silica sand, limestone, lactose and potato starch were selected as the powders. Furthermore, colloidal silica was used as a solid additive. The relationship between the tensile strength and the porosity of a powder bed containing the additive was proposed to characterize the effect of additives on the mechanical properties of the powders. Furthermore, the experimental results reported by others were able to be explained by the above relationship.† This report was originally printed in J. Soc.

PHOTOSENSITIZATION OF METHYL LINOLEATE OXIDATION BY TRYPTOPHAN IN PEPTIDES (1983)

Abstract The ability of tryptophan in peptides to photosensitize the oxidation of methyl linoleate (ML) was evaluated. Purified ML was irradiated (λ > 270 nm) alone or in the presence of a tryptophan‐containing peptide in ethanol solution. Oxidation was monitored by measuring the dienc hydroperoxides formed from ML by high performance liquid chromatography. N‐acetylphenylalanyltryptophan (NAPT) and N‐acetyltryptophan were about 2‐fold more effective as photosensitizers than leucyltryptophan and tryptophylleucine. N‐acetylphenylalanyltryptophan photolyzed in ethanol to form multiple photoproducts including N‐formylkynurenine‐type compounds. However, the NAPT photoproducts did not photosensitize the oxidation of ML and N‐formylkynurenine was about 8% as effective as NAPT. Sodium azide partially quenched the photooxidation sensitized by NAPT.
Integration of Conductivity, Transparency, and Mechanical Strength into Highly Homogeneous Layer-by-Layer Composites of Single-Walled Carbon Nanotubes for Optoelectronics (2007)

Conductive organic and composite films represent the critical component of many areas of technology. This study demonstrates that highly conductive coatings can be made by layer-by-layer (LBL) assembly of single-walled carbon nanotubes (SWNTs). These films reveal electrical conductivities of 102 to ∼103 S/m at room temperature without doping with nanotube loading as low as ∼10%. This is indicative of efficient utilization of SWNT in percolation pathways. Low SWNT loading also makes the coatings quite transparent with transmission as high as 97% for visible light. Thicker delaminated LBL films displayed conductivities of 4.15 × 104 S/m. The free-standing films were highly flexible and possessed 160 MPa of tensile strength, which makes them the strongest organic conductor. The high strength and conductivities are attributed to the unique homogeneity of the LBL assembled composites, which opens the way to future optimization of electrical, mechanical, and optical properties and to fit the needs of specific applications, which may be exemplified by transparent flexible electronics, light emitting diodes, smart windows, solar cells, sensors, structural materials, and biomedical devices.
Coupling products of amino acids to penicillin V and cephalothin: synthesis and susceptibility to carboxypeptidases and lysosomal enzymes (1988)

Amino acids have been coupled to the carboxyl group of penicillin V and cephalothin by methods that keep the beta-lactam ring intact. Derivatives were successfully obtained with both neutral (Leu, Val, Ala, Ile, Trp, Tyr, Gly) and one acidic (Glu) amino acids. The new compounds were inactive in vitro against Staphylococcus aureus or Micrococcus luteus. Incubation in the presence of purified carboxypeptidases (A, B), soluble lysosomal fractions from liver, or cellular homogenates from liver, kidney, fibroblasts, and macrophages did not allow recovery of the antibacterial activity. Injection in mice also failed to cause liberation of microbiologically active compounds. HPLC studies confirmed that the amide linkage between the antibiotic and the amino acid was not hydrolyzed in the presence of soluble lysosomal fractions from liver. However, conversion of cephalothin and cephalothin-leucine to desacetyl derivatives was observed in the presence of soluble lysosomal fractions and extracts from liver and semipurified orange peel acetylesterase(s). It is concluded that amino acid derivatives of beta-lactam antibiotics do not offer potential chemotherapeutic use as prodrugs.
ENDOTHELIOMA OF THE PLEURA (1920)

This case is reported not only because of the rarity of the occurrence of the condition, but also because of the interesting conditions which prevailed throughout the course of the illness. REPORT OF CASE History. —A white man, aged 31, first reported at sick call, Oct. 29, 1918, and was sent to a field hospital, where a diagnosis of ileocolitis was made. From there he was immediately transferred to a base hospital. There he gave a history of having had diarrhea for two weeks previously. He was suffering from headache, and incontinence of feces, but he had no fever; mentally he was stupid and somnolent. November 9, on the discovery that the right side of the chest was partially flat, 500 c.c. of serosanguineous fluid were removed. Apparently no pus cells nor organisms were found in the fluid. As the mental condition grew worse, and definite auditory hallucinations were present,

Autonomic QoS management and supervision system for Home Networks (2009)

Broadband access to the Internet at home was the first step in the emergence of so called Home Networks. In a close future, the number of appliance connected will rise and the network will become the home backbone. This lead us to a mesh architecture, in which routing will be mandatory. This paper introduces a complete system to, first, pilot the forwarding in order to ensure a proper quality of experience; and secondly to monitor and diagnosis the network from the ISP-network in order to reduce OPEX. The system is based on the knowledge plane composed of agents embedded on devices.
Effect of the substituents on the conformational behavior of five‐membered rings: Application to the cis‐ and trans‐2,5‐dimethoxytetrahydrofuran (1988)

Abstract A model is proposed which assumes that the pseudorotational potential in five‐membered rings is given by the combination of contributions from the unsubstituted ring, from the individual substituents and from interactions between pairs of substituents. The application of this model to the potentials calculated by the MM2 force field for the cis and trans ‐2,5‐dimethoxytetrahydrofuran shows that the contributions from the individual substituents explain the main features of the potentials of these disubstituted rings. The pseudorotational analysis from vicinal proton spin‐spin coupling constants 3 J HH confirms the realibility of the MM2 potentials.

Theoretical Studies of Light Scattering by Polydispersed Colloidal Systems of Spherical Particles (1964)

Abstract In order to study the light scattering of polydispersed colloidal systems of spherical particles, a weight distribution function, W(α), of the relative particle radius α has been assumed to be a modified Gaussian function with three parameters: the most probable α-value, αm; the width of the distribution, 〈Δα〉, and the dissymmetry of the distribution, Δ. The values of Yθ, which is proportional to the specific scattering intensity, for θ=45°, 90° and 135°, and the dissymmetry factor, z=Y45⁄Y135 have then been computed. In principle, it should be possible to determine three parameters of the particle size distribution, αm, 〈Δα〉 and Δ, from the observed values of three independent quantities, Y45, Y90 and Y135. It has, however, been concluded that practically the method requires very precise experiments. If one is satisfied with a distribution function of two parameters, αm and 〈Δα〉, the values of these parameters can be determined from the experimentally-obtained Y90 and z values on the basis of a chart constructed theoretically. The value of αw, which is the cubic root of weight-averaged 〈α3〉, is equal to the α value obtained from the measured specific scattering intensity by assuming that the system is monodispersed when α is small. If α is not small, the value of αw can be obtained according to the empirical equation: αw⁄α90=1+k(z⁄z90−1) The error will be within about 5% if αw&lt;1.5.

Development of Enzymes Involved in Photosynthetic Carbon Assimilation in Greening Seedlings of Maize (<i>Zea mays</i>) (1980)

Upon illumination of dark-grown maize seedlings (5 days old) with incandescent light, there occurred a nearly simultaneous increase, after a certain lag period, in the activities of enzymes engaged in the C(4) pathway and the Calvin-Benson cycle. The light-induced biosynthesis of chlorophyll (a and b) precedes the increase in enzyme activities and proceeds without lag phase. A diphasic feature in the elevation of enzyme activities as a function of the intensities of light provided was observed; the increase in enzyme activities was enhanced by light intensities greater than 10(3) ergs per square centimeter per second in comparison with light of lower intensities. Under light intensities greater than 10(3) ergs per square centimeter per second, the simultaneous addition of levulinic acid, which inhibited chlorophyll formation, markedly reduced the increase of enzyme activities. However, neither the diphasic light effect nor the inhibitory effect of levulinic acid was observed with ribulose-1,5-bisphosphate carboxylase. The enzyme activities in the dark-grown maize seedlings were enhanced by a brief irradiation with the red light and the red light effect was reversed by the following far red light treatment. The red light-induced increase in the enzyme activities did not accompany chlorophyll synthesis, and was completely inhibited by cycloheximide, indicating that enzyme synthesis rather than activation might be involved. Light may play a dual role in enzyme induction; one is as an energy source through the photosystems at high intensities and the other is presumably as a signal mediated by phytochrome at low intensities.
Molecular beam kinetics: Optical model for reactive scattering of alkali atoms and alkyl iodides (1976)

Angular distributions of reactively scattered alkali iodides have been measured for reactions of thermal beams of Rb and Cs atoms with beams of alkyl iodides RI, where R=CH3, C2H5, n- and i-C3H7, n-C4H9, and n-C5H11. When shifts expected from kinematic differences are taken into account, the qualitative features are found to confirm the results previously obtained for the analogous K atom reactions. The reaction cross sections increase with the size of the alkali atom, from ∼35 Å2 for K+CH3I to ∼45 Å2 for Rb and ∼75 Å2 for Cs. The fall off in intensity of elastically scattered alkali atoms at wide angles also increases for K→Rb→Cs. The anisotropic angular distribution of products, the magnitude of the reaction cross section, and the fall off of the wide-angle elastic scattering for the K, Rb, and Cs systems are correlated in terms of an extended optical model which simply assumes hard sphere interactions for both the entrance and exit trajectories. The reaction probability derived from the data by use of the optical model is large only for collisions which reach the repulsive wall region but even there it is well below unity for thermal energy collisions.
