An HREELS investigation of the adsorption and reaction of formic acid on the (0001)-Zn surface of ZnO (1991)

The adsorption and reaction of HCOOH on the (0001)-Zn surface of ZnO was studied using high resolution electron energy loss spectroscopy (HREELS). Fourier deconvolution was used to remove phonon-phonon and phonon-adsorbate combination losses from the HREEL spectra of the adsorbate-covered surface, allowing adsorbed species to be easily identified. Formic acid was found to dissociate on the (0001)-Zn surface to form surface formate species and surface hydroxyl groups. The HREEL spectra indicate that formates are adsorbed in a monodentate configuration on this surface. This study represents one of the first examples of the use of HREELS to characterize adsorbed organic species on a metal oxide surface.
Influence of dietary calcium on sodium and calcium intake of spontaneously hypertensive rats (1992)

Spontaneously hypertensive rats (SHRs) fed nutritionally complete diets voluntarily ingest more calcium and more NaCl solution than do their normotensive Wistar-Kyoto (WKY) controls. SHRs also have several anomalies in calcium metabolism. Given that calcium availability modulates NaCl intake of other rat strains, we examined whether sodium and calcium intake of the SHR was unusually responsive to manipulations of dietary calcium. In three experiments, groups of SHRs and WKYs ate diets differing in calcium content (0-1,000 mmol/kg) and drank solutions of sodium (50 and 300 mM NaCl or 50 mM sodium lactate) and/or calcium (50 and 110 mM calcium lactate or 50 mM CaCl2). Relative to WKYs, SHRs fed calcium-deficient diet (0 mmol Ca2+/kg) drank the same amount or less calcium solution, drank more NaCl, and increased NaCl intake more rapidly when the diet was first introduced. SHRs fed diets sufficient for normal growth (50-1,000 mmol Ca2+/kg) drank consistently more calcium and sodium solution than did WKYs. However, NaCl intake of SHRs was decreased by high-calcium diets, whereas NaCl intake of WKYs was not. Taken together, these results suggest that a mechanism dependent on the availability of calcium is at least partially responsible for the high salt intake of the SHR.
Epigenetic inactivation of <i>TSLC1</i> gene in nasopharyngeal carcinoma (2003)

Deletion of 11q23 is a common genetic aberration in nasopharyngeal carcinoma (NPC). Multiple candidate tumor suppressor genes (TSG) were mapped to this region but few of them were investigated in NPC. TSLC1 (tumor suppressor in lung cancer) is recently reported to be a putative TSG on 11q23. This gene was found to be inactivated by promoter hypermethylation in non-small cell lung carcinoma (NSCLC), liver cancer, and breast cancer. To study the role of TSLC1 gene in NPC tumorigenesis, we screened for mutations and aberrant methylation of TSLC1 gene in 5 NPC cell lines, 3 NPC xenografts, and 38 primary NPC cases. No somatic mutations of TSLC1 were detected in the NPC samples, but a 9-bp (CCACCACCA) deletion in exon 8 was found in a primary NPC and its corresponding blood sample. Bisulfite sequencing revealed aberrant methylation of TSLC1 promoter in four NPC cell lines. Loss of TSLC1 gene expression was found in two cell lines (HK-1 and CNE-2) with dense methylation. Expression of this gene was restored in these cell lines after treatment with demethylating agent 5-aza-2'-deoxycytidine. Our results showed that silencing of TSLC1 gene expression in NPC was associated with promoter hypermethylation. Promoter hypermethylation of TSLC1 gene was further illustrated in 34.2% (13/38) of primary NPCs. No aberrant promoter methylation was found in any of the four investigated normal nasopharyngeal epithelia. Frequent epigenetic inactivation of TSLC1 gene in NPC suggested that this gene is one of the target tumor suppressor genes of this endemic cancer.
Kinetic energy release in metastable ion transitions. A study by ion kinetic energy spectrometry and rrkm theory (1975)

Abstract An approach to energy partitioning using experimental data in conjunction with theoretical calculations is presented, with the McLafferty and related rearrangements occurring in the molecular ions of ketones, esters, amides and acid chlorides representing the specific reactions examined. The kinetic energy release associated with statistical partitioning of the nonfixed energy of the activated complex was calculated from unimolecular reaction theory and compared with experimental data. Calculations of the energy dependence of the rate constant and the average statistically released kinetic energy were made for 24 activated complexes corresponding to the two basic structures, cyclic and linear. The frequencies used in the calculations were all modeled upon the 2‐pentanone case with sufficient variation in the frequencies used to allow for any reasonable type of perturbation of the linear and cyclic structures. To further test that the complexes chosen were reasonable, A‐factors were determined. From a comparison of the calculated and experimental results, the contributions of the nonfixed energy of the activated complex and of the reverse activation energy to the energy release were separated. This appears to be applicable, not only to the 2‐pentanone case, but across the series of reactions studied. It is also shown that, despite the fact that these reactions release relatively small kinetic energies, the fraction due to the reverse activation energies may be large. The consequences of these observations for ion enthalpy determinations are emphasized.
Interactions of Small-Scale Physical Mixing Processes with the Structure, Morphology and Bloom Dynamics and Optics of Non-Spheroid Phytoplankton (2001)

Abstract : Our long-term goal is to understand the ecology of phytoplankton, especially the large, colonial diatoms which frequently dominate the flora of coastal shelves, upwelling areas, fjords and banks. We are interested in ways in which species-specific properties, including cell and colony size and shape interact with small-scale physical mixing processes to regulate the spatio-temporal distribution of diatoms. We wish to understand these processes in sufficient detail to be able to predict bloom dynamics, size structure and the impact of species-specific characteristics of the phytoplankton on ocean optics.
The mechanism of aqueous stress-corrosion cracking of α + β titanium alloys (2017)

In a previous paper (Cao et al., 2017) [1], a transition in fracture mode in aqueous NaCl Stress-Corrosion Cracking (SCC) of Ti-8Al-1Mo–1 V was reported. This paper attempts to unravel the operating mechanism for SCC by dislocation analysis on the Focus Ion Beam (FIB) lift-out foils from pre-crack and the SCC regions. It is shown that both basal <a> and <c + a> slips are operative in the SCC region while the basal <a> is the only activated system in the pre-crack region. Moreover, there is an increase in dislocation density in the SCC region compared to the pre-crack region. Based on these observations, combined Absorption Induced Dislocation Emission (AIDE) and Hydrogen Enhanced Localized Plasticity (HELP) is proposed to be the operating mechanisms for SCC in α+β titanium alloys.
Hybrid Calcium Phosphate-Polymeric Micelles Incorporating Gadolinium Chelates for Imaging-Guided Gadolinium Neutron Capture Tumor Therapy (2015)

Gadolinium (Gd) chelates-loaded nanocarriers have high potential for achieving magnetic resonance imaging (MRI)-guided Gd neutron capture therapy (GdNCT) of tumors. Herein, we developed calcium phosphate micelles hybridized with PEG-polyanion block copolymers, and incorporated with the clinical MRI contrast agent Gd-diethylenetriaminepentaacetic acid (Gd-DTPA/CaP). The Gd-DTPA/CaP were nontoxic to cancer cells at the concentration of 100 μM based on Gd-DTPA, while over 50% of the cancer cells were killed by thermal neutron irradiation at this concentration. Moreover, the Gd-DTPA/CaP showed a dramatically increased accumulation of Gd-DTPA in tumors, leading to the selective contrast enhancement of tumor tissues for precise tumor location by MRI. The enhanced tumor-to-blood distribution ratio of Gd-DTPA/CaP resulted in the effective suppression of tumor growth without loss of body weight, indicating the potential of Gd-DTPA/CaP for safe cancer treatment.
Expulsion Testing of an Anterior Cervical Intervertebral Fusion Cage: Factors Affecting Pull Out Resistance (2002)

Factors affecting the expulsion resistance of an anterior cervical discectomy and fusion (ACDF) device in a cadaver model were investigated. Two specimen specific properties were considered; bone mineral density (BMD), and donor age. Also, two surgical procedures were used, representing two different degrees of destabilization of the intervertebral joint. Expulsion forces averaged 176 N (S.D. 60 N) for all specimens. No statistically significant difference in expulsion force was found between the specimens in the two surgical groups. However, expulsion force showed significant correlation to both BMD and donor age, with correlation coefficients of 0.81 and −0.83 respectively.
How to write parallel programs: a guide to the perplexed (1989)

We present a framework for parallel programming, based on three conceptual classes for understanding parallelism and three programming paradigms for implementing parallel programs. The conceptual classes are result parallelism, which centers on parallel computation of all elements in a data structure; agenda parallelism, which specifies an agenda of tasks for parallel execution; and specialist parallelism, in which specialist agents solve problems cooperatively. The programming paradigms center on live data structures that transform themselves into result data structures; distributed data structures that are accessible to many processes simultaneously; and message passing, in which all data objects are encapsulated within explicitly communicating processes. There is a rough correspondence between the conceptual classes and the programming methods, as we discuss. We begin by outlining the basic conceptual classes and programming paradigms, and by sketching an example solution under each of the three paradigms. The final section develops a simple example in greater detail, presenting and explaining code and discussing its performance on two commercial parallel computers, an 18-node shared-memory multiprocessor, and a 64-node distributed-memory hypercube. The middle section bridges the gap between the abstract and the practical by giving an overview of how the basic paradigms are implemented. We focus on the paradigms, not on machine architecture or programming languages: The programming methods we discuss are useful on many kinds of parallel machine, and each can be expressed in several different parallel programming languages. Our programming discussion and the examples use the parallel language C-Linda for several reasons: The main paradigms are all simple to express in Linda; efficient Linda implementations exist on a wide variety of parallel machines; and a wide variety of parallel programs have been written in Linda.
Spatial Vectorcardiography in the Wolff‐Parkinson‐White Syndrome: Correlation with Epicardial Mapping Findings (1984)

The spatial vectorcardiograms (VCG) of 13 patients with WPW syndrome due to single accessory pathways were analyzed and correlated with the excitation analysis obtained on epicardial mapping. The azimuth angle of the initial 10 ms cardiac vector was greater than + 90 degrees (directed right and anteriorly) in patients with a left ventricular free wall; it ranged between 0 degree to 90 degrees (left and anteriorly) in those with a left or right paraseptal free wall and was -30 degrees (left and posteriorly) in one patient with a right ventricular free wall location. The elevation angle of the initial 10 and 20 ms cardiac vector was either zero or positive (inferiorly directed) in those with right and left ventricular free wall pathway. Among six patients with a paraseptal location, the elevation angle was negative (superiorly directed) in four and positive in two. Both the patients with a clockwise inscription of a QRS loop in the horizontal plane (HP) had pathways located to the left ventricle. Among the paraseptal group, at surgery, the accessory pathway could not be excised in two in spite of dissection very close to the IV (interventricular) septum. The elevation angle in both these patients was markedly negative (-45 degrees and -62 degrees) in contrast to the other in whom surgical excision was successful.+
Multi-Fascicle Model Reconstruction from Acquisitions at a Single b-value with a Population-Informed Prior (2013)

Purpose. Diffusion tensor images (DTI) have been widely used to characterize the white matter microstructure. The incapacity of DTI to represent crossing pathways has motivated the developement of novel diffusion models, such as the multi-tensor models. However, to estimate a multi-tensor model, one needs to acquire the diffusion weighted images (DWI) at multiple b-values, unlike the common single-shell HARDI acqusition that has been used for years. This incompatibility comes with a high financial burden since studies based on single-shell HARDI acquisitions should be renewed and completed with novel acquisitions. In this study, we propose a method to retrospectively reconstruct a multi-tensor model from single-shell HARDI data, based on a multi-tensor atlas.

In situ identification of T lymphocyte subsets and HLA-DR expressing cells in the human skin tuberculin reaction. (1982)

T lymphocyte subsets and HLA-DR expressing cells were studied with an immunohistochemical double staining technique in frozen sections of human skin 6, 48 and 96 hr after intradermal PPD injections. The number of lymphocytes reacting with monoclonal Leu 1 antibodies (all mature peripheral T cells) increased with time. The majority of the T lymphocytes at 48 and 96 hr reacted with Leu 3a ('helper/inducer' phenotype) antibodies and a few with Leu 2a ('suppressor/cytotoxic' phenotype) antibodies. Apposition of T lymphocytes of both subsets to HLA-DR expressing cells occurred in the dermis as well as in the epidermis. The study gives a morphological picture of the cell-mediated immune reactions in delayed type of hypersensitivity consistent with in vitro experiments on proliferative responses to soluble antigens.

In the search of alternative cleaning solutions for MBR plants (2008)

The objective of the study was to identify alternative cleaning reagents to chlorine for membrane permeability regeneration in MBR applications. Indeed, chlorine is prohibited in some countries because of the formation of by-products such as THM. The study was focused on the comparison of ten cleaning reagents performances and in particular on their ability to remove irreversible fouling. The tests were carried on with the A3 Water Solutions' Maxflow membrane (flat sheet membrane). A specific experimental protocol was defined at lab scale to develop an irreversible fouling by filtering sludge supernatant. The more promising reagents at lab scale were then tested on the A3 membrane continuously immersed in a MBR pilot plant functioning under typical biological conditions (MLSS=11 g/l; SRT=28 days). A full scale test was finally performed with hydrogen peroxide, one of the best reagents. Chlorine was taken as reference for all performed tests. The cleaning performances of the selected reagents were different at the different scales, probably due to the difficulty to obtain an irreversible membrane fouling at larger scales. This testing procedure will be reproduced with other membrane materials to have a better understanding of interactions between irreversible fouling, material nature and chemical reagents.

Dynamic Object Process Graph Extraction for Program Understanding and Protocol Recovery (2007)

An object process graph (OPG) is a view on the control flow graph from the perspective of a single object. Such a graph can be extracted using static or dynamic program analysis. Similar to program slicing, OPG extraction is an enabling technique with applications in many reverse engineering tasks. This Ph.D. thesis is about dynamic extraction of such OPGs and their application for program understanding and protocol recovery. In a first step, the author introduced methods for online and offline construction of dynamic OPGs, supporting different languages. The second step is the further transformation and application of the resulting graphs. The goal of this thesis is to show how they can be used for program comprehension and protocol recovery, and that these two approaches are really beneficial

Introduction to distributed mode loudspeakers (DML) with first-order behavioural modelling (2000)

A simple equivalent circuit of a distributed mode loudspeaker (DML) is described, which is accessible to engineers not specialised in acoustics. The DML is an acoustic radiator, the electrical, mechanical and acoustical properties of which differ radically from conventional moving coil transducers. DML radiation results from uniformly distributed, free vibration in a stiff, light panel and not pistonic motion. To enable acoustic engineers to use existing software programs to model their application of DML technology, an efficient equivalent circuit is developed. Within the constraints of the model, velocities and displacements of the various elements can be calculated, and the radiated acoustic power and pressure predicted.
A SiGe switched LNA for X-band phased-arrays (2012)

This paper presents a switched low-noise amplifier (LNA), for the first time at X-band (8–12 GHz) frequencies, fabricated in 0.25-µm SiGe BiCMOS process. The switched LNA is based on single stage bipolar cascode topology to achieve lower noise figure and higher gain, simultaneously. The switching circuitry is designed by a series isolated NMOS switch. We also present, for the first time in switched LNAs, the utilization of resistive body floating technique to increase power handling (IP 1dB ) in bypass mode. Measurement results show that, in gain mode, LNA achieves a noise figure of 1.6–1.9 dB and a gain of 9.5–11.5 dB in 8–12 GHz band. The input-referred P 1dB is −6 dBm at 10 GHz and the power consumption is 18.6 mW. In bypass mode, the switched LNA achieves a measured insertion loss of 6 dB and an input-referred P 1dB of 17.4 dBm at 10 Ghz, with 1 µW power consumption. The chip area is 0.52×0.58 mm2.
FPGA-based FIR filters using digit-serial arithmetic (2002)

This paper describes the use of digit-serial arithmetic for compact and efficient implementations of real-time DSP applications on field programmable gate arrays (FPGAs). As an example, the implementation of a digit-serial 5-tap FIR filter on a Xilinx XC4010 FPGA is considered. An analysis of the performance comparison of several FIR filters is described. The results show that digit-serial designs with a digit-size of 2 bits have about 17% smaller area-time product than those of a bit-serial implementations.
