Study of crystallographic orientations in the diamond film on cubic boron nitride using Raman microprobe (1990)

We have measured Raman spectra of a diamond film prepared on the (111) surface of cubic boron nitride(c-BN) by the dc plasma chemical vapor deposition method. The polarization property of the Raman line of diamond agrees well with that of LO phonon for the (111) surface of c-BN. The agreement between the polarization property of Raman lines of diamond and c-BN indicates a possibility of the heteroepitaxial growth of the diamond film on the (111) surface of c-BN. It is found that the diamond layers on c-BN are under tensile stress of 2.2×1011 dyn/cm2. The value of the corresponding tensile strain agrees well with the lattice mismatch calculated from the lattice constants of c-BN and diamond, supporting the possibility of the heteroepitaxial growth of the diamond film. Raman spectroscopy is a powerful technique not only to estimate the stress in the diamond film but also to determine the crystallographic orientation.
Cancer Therapy With Radiolabeled Antibodies An Overview (1995)

Considerable progress has been achieved during the last two decades in the use of radiolabeled tumor-selective monoclonal antibodies in the diagnosis and therapy of cancer. The concept of localizing the cytotoxic radionuclide to the cancer cell is an important supplement to conventional forms of radiotherapy. In theory the intimate contract between a radioactive antibody conjugate and a target cell enables the absorbed radiation dose to be concentrated at the site of abnormality with minimal injury to the normal surrounding cells and tissues. A variety of approaches and combinations of this strategy are now being pursued. This synopsis attempts to summarize the theoretical and biological basis for radio-immuno-therapy (RIT), and to review present efforts to further develop this treatment. Some of the critical issues in RIT are highlighted, and novel ways of improving the therapeutic indices of these radiopharmaceuticals are outlined. The attention is focused on the results obtained in clinical trials employing RIT. Encouraging complete response rates have recently been reported in patients with non-Hodgkin's lymphoma resistant to combination chemotherapy. More modest results have been obtained in patients with solid cancers. The promises and hurdles in creating tumor-selective radiolabeled antibodies for cancer therapy are discussed, and prospects for further improvements are presented.
The bacterial transformation of abietic acid (1968)

An Alcaligenes species, which was isolated from soil, can utilize abietic acid as its sole carbon source. During growth, the bacterium transforms abietic acid into 5alpha-hydroxyabietic acid (I, R=OH), a product considered to be 7beta-hydroxy-13-isopropyl-8xi-podocarp-13-en-15-oic acid (II, R=H) and a compound, C(20)H(28)O(3), which is believed to be an epoxy-gamma-lactone.
Learning High Dynamic Range from Outdoor Panoramas (2017)

Outdoor lighting has extremely high dynamic range. This makes the process of capturing outdoor environment maps notoriously challenging since special equipment must be used. In this work, we propose an alternative approach. We first capture lighting with a regular, LDR omnidirectional camera, and aim to recover the HDR after the fact via a novel, learning-based inverse tonemapping method. We propose a deep autoencoder framework which regresses linear, high dynamic range data from non-linear, saturated, low dynamic range panoramas. We validate our method through a wide set of experiments on synthetic data, as well as on a novel dataset of real photographs with ground truth. Our approach finds applications in a variety of settings, ranging from outdoor light capture to image matching.
Partial k-space MRI reconstruction using a modified Homodyne approach (2010)

A drawback of the conventional Homodyne approach which is originated from the communication theory, is that the reconstructed image acquired by the Magnetic Resonance Imaging (MRI) modality is blurred. Thus, a new homodyne based-approach is proposed in order to improve the quality of the MRI image. Consequently, the segmentation of boundaries of a particular organ (or any structure), a crucial step for medical diagnosis in the estimation of its size as well as the computation of various functional parameters is improved. The proposed approach is evaluated visually by segmenting the MR brain images using an active contour “snake” model as well as by subtracting the reconstructed images from the original image. Also, the evaluation is performed quantitatively using different criteria (the Performance Test and the Root Mean Square) for various percentage of the collected k-space. The proposed approach is compared with other MRI Reconstruction techniques such as the Homodyne approach, the Zero-filling approach, the POCS approach and the conjugate Synthesis approach. Consequently, its performance is much better than the indicated conventional techniques.
Changes in the microbiological quality of shellfish, brought about by treatment with high hydrostatic pressure (2003)

Abstract Four types of shellfish, mussels, prawns, scallops and oysters, were pressure treated at 300, 400, 500 and 600 MPa for 2 min at 20 °C and stored for up to 28 days at 2 °C. The shellfish were sampled before and after pressure treatment and at 7-day intervals for total aerobic counts, psychrotrophic counts, pseudomonads and coliforms. Pressure treatment readily inactivated psychrotrophic bacteria, coliforms and pseudomonads. Randomly selected isolates were identified from the shellfish before and after pressure treatment and after storage at 2 °C. The range of bacteria present in the shellfish decreased after pressure treatment. This was predominantly because of inactivation of Gram-negative bacteria leading to an increase in the proportion of Gram-positive species isolated. The main types of bacteria isolated from pressure-treated shellfish, after storage, were Bacillus, Acinetobacter/Moraxella and lactic acid bacteria. Together these made up 96% of the bacteria isolated from all the pressure-treated shellfish.
The kinetics of electrode reactions. I and II (1938)

Abstract In any surface reaction taking place in a Solution, it is clear that the concentration of the reactants in the vicinity of the surface must fall. If the concentration in the bulk of the solution remains constant, a steady state may finally be reached, in which the rate of replenishment of the solution in this region, from the bulk, is equal to the rate at which the reactant in question is used up. But, in general, such a state is only attained when the concentration at the surface is less than that in the rest of the solution. If the reaction considered is an electrode reaction, these concentration changes may affect the electrode potential. This question is therefore of importance in the study of overpotential, and of the kinetics of electrode processes generally. The overpotential at an electrode is defined as the potential difference between this electrode and a similar unpolarized reversible electrode in the same solution. In practice this reference electrode is usually situated outside the region affected by the concentration changes near the electrode at which the reaction is taking place. The measured potential difference between the two electrodes, i.e. the measured overpotential, may therefore include a term due to the concentration difference.
Authorization and Attribute Certificates for Widely Distributed Access Control (1998)

We describe a system whose purpose is to explore the use of certificates for the distributed management of access rights for resources that have multiple, independent, and geographically dispersed stakeholders. The stakeholders assert their use-conditions in authorization certificates and designate those trusted to attest to the corresponding attributes. These use-conditions implicitly define access groups through their requirement for certain attributes. All use-conditions must be satisfied simultaneously, so the actual access group is the intersection of all of the groups. A policy engine collects the use-condition certificates and attribute certificates when a user attempts to access a particular resource. If all of the use-conditions are met, a capability is generated for the resource. The policy engine can provide several different policy models depending on whether any relationship is established among the useconditions. The system architecture and implementation ...
Merrifield resin supported peroxomolybdenum(vi) compounds: recoverable heterogeneous catalysts for the efficient, selective and mild oxidation of organic sulfides with H2O2 (2013)

We have generated new heterogeneous catalysts by immobilizing dioxomonoperoxomolybdenum(VI) on amino acid functionalized Merrifield resin, which exhibit excellent activity, stability and selectivity for the oxidation of thioethers and dibenzothiophene (DBT) to the corresponding sulfoxides or sulfones by H2O2 at ambient temperature. The synthetic protocols are high-yielding, halogen-free, environmentally clean and safe, and operationally simple. The catalysts, [MoO2(O2)(L)2]2−-MR [L = valine (MRVMo) or alanine (MRAMo) and MR = Merrifield resin] were prepared by reacting H2MoO4 with 30% H2O2 and the respective amino acid functionalized resin, at near neutral pH. The compounds were characterized by elemental analysis, spectral studies (FTIR, Raman, 13C NMR and 95Mo NMR, diffuse reflectance UV-Vis and XPS), SEM, EDX, XRD, Brunauer–Emmett–Teller (BET) and TGA-DTG analysis. The easy recyclability of the catalysts for several catalytic cycles without change in activity and selectivity, their complete chemoselectivity towards the sulfur group of substrates bearing other oxidation prone functional groups, are important “green” attributes of these catalysts.
Protease inhibitors and prevention of cross resistance. (1995)

A controversy has developed, initiated by a paper in the April 1995 issue of Nature, over the use of protease inhibitors among AIDS patients. The article, written by Jon Condra and Emilio Emini, reported that HIV developed resistance to indinavir (Merck & Co.'s protease inhibitor), and all other protease inhibitors as well. In response to the study on Merck's product, Roche released information suggesting that their protease inhibitor, saquinavir, does not cause resistance nearly as quickly or as much. Merck is currently studying the combination of indinavir and AZT, and Abbott Laboratories is examining the effects of AZT, ddC, and ritonavir. These studies imply that optimal multi-drug combination therapy should delay drug resistance as well as cross-resistance. The implications are promising for patients with HIV and AIDS. Pharmaceutical companies are conducting additional studies to develop new reverse transcriptase inhibitors and to determine the effectiveness of the combination of two or more protease inhibitors. Each drug trial demonstrates the relationship between dosing and resistance; patients are advised to adhere completely to dosing instructions.

Civil society and social order: demarcating and combining market, state and community (2000)

Social change is currently occurring in three directions: political democratisation, economic globalisation, and the spread of postmodern culture. The consequent problems cannot be treated by any of the three known methods of macrosocial regulation: the state, the market, the community. ‘Civil society’ has been assigned the role of synthetic and pluralistic rationalisation.
Distinct ERG rearrangement prevalence in prostate cancer: higher frequency in young age and in low PSA prostate cancer (2013)

ERG+ tumors manifest clinically at lower PSA levels and their prevalence is age dependent. This suggests acceleration of tumor development by ERG overexpression that results in earlier tumor detection in young patients. Long-term results are warranted to determine the impact of ERG overexpression on disease outcome.
Mutagenesis of Glu403 to Cys in rabbit neutral endopeptidase-24.11 (neprilysin) creates a disulphide-linked homodimer: analogy with endothelin-converting enzyme (1997)

Neutral endopeptidase-24.11 (NEP; neprilysin; EC 3.4.24.11) and endothelin-converting enzyme (ECE) are related zinc metallopeptidases involved in the processing of biologically active peptides. Only ECE, however, exists as a disulphide-linked homodimer. The covalent linkage in rat ECE is between Cys412 in each subunit, which is equivalent to Glu403 in rabbit NEP. Here we report that directed mutagenesis of Glu403 to cysteine in rabbit NEP creates a disulphide-linked homodimer, as revealed by transient transfection in COS-1 cells and SDS/PAGE of a membrane fraction. Under reducing conditions, both the mutant (E403C) and the wild-type NEP migrate as a polypeptide of 92 kDa. However, under non-reducing conditions, the Mr of the wild type remains unchanged, whereas that of the mutant is doubled. Co-transfection of wild-type ECE and E403C NEP cDNA did not result in the production of a NEP-ECE heterodimer. Comparison of the kinetic constants for wild-type and E403C mutant NEP with either [D-Ala2,Leu5]enkephalin or 3-carb oxypropanoyl-alanyl-alanyl- leucine-4-nitroanilide(Suc-Ala-Ala-Leu-NH-Np) as substrate show a decrease of approx. 50% in Vmax/Km for the mutant form. The IC50 value for inhibition of the mutant by phosphoramidon or thiorphan is increased 3-fold and 5-fold respectively. Although NEP and ECE exhibit only about 40% identity and differ substantially in substrate specificity and some other characteristics, these data indicate that they have considerable similarity in three-dimensional structure, allowing dimer formation in the mutant NEP with the disulphide link probably occurring in a hydrophilic surface loop.
Significant Positional Isomeric Effect on Structural Assemblies of Zn(II) and Cd(II) Coordination Polymers Based on Bromoisophthalic Acids and Various Dipyridyl-Type Coligands (2010)

Seven Zn(II) and Cd(II) coordination polymers, formulated as {[Zn2(5-Br-ip)2(bpy)(H2O)]·2H2O}n (1), {[Zn(5-Br-ip)(bpa)(H2O)]}n (2), {[Cd(5-Br-ip)(bpp)(H2O)]}n (3), {[Zn(5-Br-ip)(bpe)]}n (4), {[Zn2(4-Br-ip)2(bpy)]·H2O}n (5), {[Zn(4-Br-ip)(bpa)(H2O)]}n (6), and {[Cd(4-Br-ip)(bpp)]}n (7), were prepared by hydrothermal reactions based on 4-bromo- or 5-bromoisophthalic acid (4-Br-H2ip or 5-Br-H2ip) and different dipyridyl-type coligands 4,4′-bipyridyl (bpy), 1,2-bi(4-pyridyl)ethane (bpa), 1,3-di(4-pyridyl)propane (bpp), and 1,2-di(4-pyridyl)ethene (bpe). All complexes 1−7 were characterized by elemental analysis, IR spectra, and X-ray single-crystal diffraction. Complex 1 is a 2D (6,3) coordination network and further assembled into a 3D framework via π−π stacking interactions. Complex 2 shows a 1D coordination array and further forms a 2D supramolecular network via H-bonding interactions. Complex 3 has a 2-fold interpenetrating 3D diamond framework. Complex 4 is a 3-fold interpenetrating 3D network with CdSO4 topology, constructed from alternately left- and right-handed helical arrays. Complex 5 has a 3D (3,4)-connected network with (4·82)(4·82·103) topology. Complex 6 features a 1D coordination chain and further forms a 2D helical supramolecular pattern by H-bonding. Complex 7 exhibits a (3,5)-connected 2D layer with the Schläfli symbol of (42·6) (42·67·8). The results reveal that the diverse coordination networks of 1−7 can be adjusted by the different dispositions of the -Br substituent of isophthalate building blocks, as well as the metal ions and the dipyridyl coligands. Moreover, the luminescent properties of the complexes have been investigated.

Small-volume waveguide-section high Q microcavities in 2D photonic crystal slabs (2004)

A series of microcavities in 2D hexagonal lattice photonic crystal slabs are studied in this paper. The microcavities are small sections of a photonic crystal waveguide. Finite difference time domain simulations show that these cavities preserve high Q modes with similar geometrical parameters and field profile. Effective modal volume is reduced gradually in this series of microcavity modes while maintaining high quality factor. Vertical Q value larger than 10(sup6) is obtained for one of these cavity modes with effective modal volume around 5.40 cubic half wavelengths [lambda/2nslab)(sup3)]. Another cavity mode provides even smaller modal volume around 2.30 cubic half wavelengths, with vertical Q value exceeding 10(sup5).
An MOS chip for surface impedance measurement and moisture monitoring (1980)

Surface impedance measurements are employed in a variety of applications such as moisture sensing (1), (2). Sheet resistances as high as 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">16</sup> Ohms/sq are often encountered (3), and reliable measurements are difficult to obtain.

A system for automated iris recognition (2002)

This paper describes a prototype system for personnel verification based on automated iris recognition. The motivation for this endeavour stems from the observation that the human iris provides a particularly interesting structure on which to base a technology for noninvasive biometric measurement. In particular, it is known in the biomedical community that irises are as distinct as fingerprints or patterns of retinal blood vessels. Further, since the iris is an overt body its appearance is amenable to remote examination with the aid of a computer vision system. The body of this paper details the design and operation of such a system. Also presented are the results of an empirical study where the system exhibits flawless performance in the evaluation of 520 iris images.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Series-Connected Saturable Reactor with Control Source of Comparatively Low Impedance (1950)

The object of this analysis is to shed light onto the mechanics of magnetic-amplifier operation and to derive simple, and yet reasonably accurate, formulas. The analysis deals with the effects of various parameters, such as voltage, frequency, load resistance, and feedback. The various mathematical expressions are condensed into a nondimensional, normalized master graph which completely describes the steady-state operation of the magnetic amplifier under consideration. Speed of response and its relation to the gain are also investigated. The formulas and conclusions are verified by test data.

When merging and branch predictors collide (2014)

Merging is a building block for many computational domains. In this work we consider the relationship between merging, branch predictors, and input data dependency. Branch predictors are ubiquitous in modern processors as they are useful for many high performance computing applications. While it is well known that the performance and the branch prediction accuracy go hand-in-hand, these have not been studied in the context of merging. We thoroughly test merging using multiple input array sizes and values using the same code and compile optimizations. As the number of possible keys increase, so the do the number of branch mis-predictions - resulting in reduced performance. The reduction in performance can be as much as 5X. We explain this phenomenon using a visualization technique called Merge Path that intuitively shows this. We support this visualization approach with modeling, thorough testing, and analysis on multiple systems.
