Effects of Combined Thermal and Mechanical Loading on the Fatigue of Solder Joints (2022)

Currently in the electronics industry, Finite Element (FE) models are widely used as tools for reducing design costs. However, to have confidence in these models, they must closely match real world test results, including time to failure and failure mode. In the past, laboratory test data have been used to supplement, refine, and validate the FE models by means of a correlation between thermal variations and cycles to failure. In this work, mechanical loading is applied as well. Test coupons populated with components are tested in an apparatus that applies cyclic four point bending simultaneously with thermal cycles. This bending is regulated to a given surface strain measured by a thermally insensitive strain gauge mounted on the surface of the printed circuit board (PCB). In addition to the mechanical loading, the PCB is enclosed in a thermal chamber to provide synchronized cyclic thermal loading as well. Electrical continuity and resistance in the solder joints is monitored, and the specimens are tested until failure criteria, usually based on detection of an open circuit, are met.
Bioinspired Synthesis of All‐in‐One Organic–Inorganic Hybrid Nanoflowers Combined with a Handheld pH Meter for On‐Site Detection of Food Pathogen (2016)

With a mild elaborately bioinspired one-pot process, Con A-GOx-CaHPO4 nanoflowers are prepared. Employing the as-prepared all-in-one hybrid nanoflowers as signal tags, a simple but potentially powerful amplification biosensing technology for the detection of food pathogen with excellent simplicity, portability, sensitivity, and adaptability is achieved.
A Tactile Sensing Finger Tip for a Dextrous Hand (1987)

A tactile sensor was designed into the finger tips of a multifinger dextrous hand. The sensor features complete coverage of the cylindrical and hemispherical end portions of the finger. An 8X8 array is used based on standard capacitive sensing techniques. An analysis of appropriate sensor depth has been used to allow accurate localization of contacts, and reduced spatial aliasing. A comparison has been done between the cylindrical sensor and a simple two dimensional stress strain model. The effect of skin thickness and sensor depth on sensitivity are analyzed. Preliminary methods for deter-mining contact locatiot, total force, and tangential force with just normal deflection sensors have been implemented.
<scp>L</scp>-Histidinol in experimental cancer chemotherapy: improving the selectivity and efficacy of anticancer drugs, eliminating metastatic disease and reversing the multidrug-resistant phenotype (1992)

Human cancer chemotherapy is limited by two major problems: the failure of commonly used anticancer drugs to act against tumor cells in a specific manner and the ability of malignant cells to resist killing by antineoplastic agents. Experimentally, both of these problems can be solved by using L-histidinol in combination with conventional anticancer drugs. A structural analogue of the essential amino acid L-histidine and an inhibitor of protein biosynthesis. L-histidinol improves the selectivity and the efficacy of a variety of cancer drugs in several transplantable murine tumors. Furthermore, L-histidinol circumvents the drug-resistant traits of a variety of cancer cells, including those showing multidrug resistance. This review will summarize these properties of L-histidinol, present new evidence on its ability to increase the vulnerability of both drug-sensitive and drug-resistant human leukemia cells to various anticancer drugs, and show that, in addition to inhibiting protein synthesis, L-histidinol acts as an intracellular histamine antagonist. The establishment of a connection between the latter mechanism and the capacity to modulate anticancer drug action has resulted in a clinical trial in the treatment of human cancer.
Human Papilloma Virus Type I Purified from Human Genital Warts (1981)

Human wart virus (HPV) was isolated from a pool of genital warts. The electrophoretic mobility of virion proteins was studied by SDS polyacrylamide gel electrophoresis and showed the same pattern as that obtained with HPV-1. The analysis of DNA after restriction enzyme digestion with the endonucleases Hind III and Hae III, and nucleic acid hybridization did not show any difference with HPV-1. The viral particles were agglutinated by anti-HPV-1 serum, as shown by electron microscopic particle agglutination test. Furthermore, the immunological properties of this virus were investigated with guinea pig antiserum. Serologically, no antigenic cross-reaction between common and genital wart viruses were shown by immunodiffusion and immunofluorescence tests, whereas cross-reactions were detected between plantar and genital wart viruses. These results allow to think that HPV-1 can induce plantar warts as well as genital warts.
Efficient Multigram Synthesis of the Repeating Unit of Gallic Acid-Triethylene Glycol Dendrimers (2011)

A multigram synthesis of the repeating unit of GATG (gallic acid-triethylene glycol) dendrimers is described through an efficient and cost-effective route. These conditions overcome major problems precluding scaling up and afford product in excellent overall yield and purity. Special attention has been paid in this process to green chemistry principles: atom economy, safety, and waste reduction. This scheme could be easily adapted for the preparation of similar dendritic systems.
Prophylactic Efficacy of a Quadrivalent Human Papillomavirus (HPV) Vaccine in Women with Virological Evidence of HPV Infection (2007)

Among women positive for 1-3 HPV vaccine types before vaccination, the quadrivalent HPV vaccine protected against neoplasia caused by the remaining types. These results support vaccination of the general population without prescreening.
Low attendance of patients with intermittent claudication in a German community-based walking exercise program. (2012)

Although physical exercise improves symptoms and mobility of patients with intermittent claudication, only about one-third of them is commencing an exercise program. Through lacking initiation and discontinuation, only a small percentage of claudicants permanently engages in a walking exercise program.

Genetic control of immune response in mice to derivatives of multichain polyproline differing in the optical configuration of component amino acids (1973)

Abstract The immune response of two inbred mouse strains, DBA/1 and SJL, to eight synthetic polypeptides of the general formulae, poly(Tyr, Glu)‐poly Pro—polyLys and poly(Phe, Glu)‐polyPro—polyLys, differing in the optical configuration of the amino acids composing the macromolecules, was compared. SJL mice responded predominantly to the polyPro—polyLys moieties of either optical configuration in the eight enantiomorphs. In both strains of mice tested, immunization with polypeptides of the formula poly(Tyr, Glu)‐polyPro—polyLys leads to antibodies specific for the polyproline moiety mainly. DBA/1 mice are low responders to 701, poly( L Tyr, L Glu)‐poly L Pro—poly L Lys, whereas they elicit a good immune response to polyDPro—polyDLys when immunized with 713, poly(DTyr, DGlu)‐polyDPro—polyDLys, and with 711, poly( L Tyr, L Glu)‐polyDPro—polyDLys. It is of interest that mice of the DBA/1 strain responded well to 715, poly(DTyr, DGlu)‐poly L Pro—poly L Lys with antibodies specific to poly‐ L ‐proline. Since this polymer is metabolized slowly and incompletely similarly to antigens composed exclusively of D ‐amino acids, it is likely that the slow metabolism affects the ability of this mouse strain to respond to this immunogen. DBA/1 mice responded predominantly to the ( L Phe, L Glu) region when immunized with 702, poly( L Phe, L Glu)‐poly L Pro—poly L Lys. Since they are high responders to ( L Phe, L Glu) and to poly D Pro—poly D Lys, they elicited antibodies to both immunopotent regions of 712, poly( L Phe, L Glu)‐poly D Pro—poly D Lys. Although DBA/1 mice are high responders to ( L Phe, L Glu) they did not respond to D ‐amino acid analogues of these peptides, and immunization of this mouse strain with 714, poly( D Phe, D Glu)‐poly D Pro—poly D Lys, and with 716, poly( D Phe, D Glu)‐poly L Pro—poly L Lys, elicited anti‐polyproline antibodies only. The results of this study show that the optical configuration of the amino acids composing an antigen plays an important role in the genetic control of the ability to respond to the immunogens investigated.
Corrosion behaviour of molybdate–phosphate–silicate coatings on galvanized steel (2009)

In this work, a Cr-free conversion layer based on molybdate–phosphate–silicate (MPS) was synthesised on a galvanized steel by simple immersion and its corrosion behaviour was compared to that of a typical chromate layer. Stationary electrochemical techniques and electrochemical impedance spectroscopy (EIS) were employed to highlight the corrosion mechanisms of both coatings in different NaCl concentrations, immersion times and pH. Contrary to the chromate layer, the MPS coating showed good electrochemical stability even in concentrated NaCl solutions and remarkable electrochemical efficiency. With increasing time, two corrosion stages were associated with the two likely sublayers of the MPS coating. Furthermore, the MPS coating behaved better than the chromate layer in acidic and alkaline pH, especially the latter as a compact corrosion product layer formed. Finally, each coating/electrolyte interface was characterised by an electrical equivalent circuit giving a satisfactory correlation between the experimental and the calculated impedance. It derived that the MPS could be an environmentally friendly alternative to chromating.
A scalable pipelined architecture for fast buffer SRAM's (2002)

The design of large synchronous buffer SRAMs for packet switching and signal processing applications is described. Called Scalable Cellular RAM (SCRAM), the approach configures memory blocks in a 2-D array with fully pipelined address and data distribution. The memory is scalable in that the access frequency is determined by the access time of a single block and is independant of the number of blocks. An experimental 0.5 /spl mu/m CMOS 256 Kb SCRAM chip is described that operates at 240 MHz. Simulation results show that larger arrays are feasible using the suggested power reduction techniques.
Well-size-controlled Colloidal Gold Nanoparticles Dispersed in Organic Solvents (2001)

The preparation of well-size-controlled colloidal gold nanoparticles in organic solvent is presented. After the preparation of well-size-controlled aqueous colloidal gold particles, we changed the solvent to an organic one. This technique is required to enable a chemical reaction between gold particles and hydrophobic molecules, since a colloidal gold solution is typically prepared in water using a reduction process. We also investigated the stability of the gold particle suspension, and found that the stability decreases in the sequence of water, ethanol, chloroform, and benzene solution.
Contrôle moléculaire des propriétés des polymères conducteurs (1991)

Le greffage sur les polymeres conducteurs, de recepteurs selectifs permettant la transduction d'informations externes en signaux electriques, constitue l'objectif a long terme de ce travail. Nous utilisons la substitution en position 3 du thiophene ou du pyrrole pour fonctionnaliser la structure polyaromatique sans en detruire les proprietes conductrices et electroactives. Le potentiel d'electropolymerisation du thiophene etant relativement eleve, la modification structurale a ete realisee a l'aide de groupements ether. L'emploi d'un bras espaceur de longueur suffisante permet d'obtenir des polymeres conducteurs portant sur chaque maillon heterocyclique, un groupement chiral relativement volumineux tel qu'un groupe terpenique. Des modifications variees des proprietes d'interface des films de polypyrrole en fonction de la nature du substituant, sont mises en evidence dans des systemes electrolytiques. Ce travail a permis d'aboutir a une optimisation exceptionnelle de la reversibilite du couple redox du polypyrrole dans les milieux organiques. La substitution du polymere par des groupements acide carboxylique induit une sensibilite lineaire du couple redox aux ph acides et un transport de cations lors de la transition electrochimique au lieu du transport d'anions classiquement observe. La solvatation des entites au sein d'un milieu electrolytique ne permet pas d'observer des interactions de faible energie entre l'electrolyte et le polymere. Le fonctionnement de recepteurs elabores sur la chaine conductrice exige un dispositif experimental different
Electrochemical detection of localized mixing produced by ultrasonic flexural waves (2002)

Localized fluid mixing caused by both standing and traveling flexural waves in 4 mu m thick membranes of low-stress silicon nitride, aluminum, and piezoelectric zinc oxide has been observed. Initial work on quantifying the mixing action using a ferri-ferrocyanide electrochemical cell is presented. One electrode is fabricated directly on the membrane; the cell current, limited by diffusion, increases from the enhanced ion transport due to the mixing. For a cell bias of 0.5 V, an increase in the limiting current from 4.2 mA without mixing to 6.6 mA with standing waves driven by 10 V at 5.0 MHz was observed. This is roughly equivalent to a rotating disk electrode spinning at 140 rpm. Possible applications include increasing the speed of amperometric sensors and as components in integrated microflow systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Cystic Fibrosis and the Innate Immune System: Therapeutic Implications (2011)

Cystic Fibrosis (CF), the most common autosomal lethal disorder in Caucasians, is caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Although CF is multi-organ disease, the lung pathology is the chief cause of morbidity and mortality of CF patients. The hallmarks of CF lung disease are respiratory infection by opportunistic pathogens and a deranged inflammatory response. However, clinical and experimental data suggest that CF is a hyperinflammatory disorder which can arise in the absence of infection. Laboratory and animal studies suggest that CFTR is involved in regulating some neutrophil and macrophage functions and indicate that altered properties of immune cells may contribute to the dysregulated inflammation in the CF lung. Moreover, recent investigations point out to the involvement of lymphocyte subpopulations in the onset of an altered immune response to pathogens. The development of novel therapies aimed to reduce the inflammatory and regulate immune responses, including stem cell-based treatment, will be presented.

From GAN to WGAN (2019)

This paper explains the math behind a generative adversarial network (GAN) model and why it is hard to be trained. Wasserstein GAN is intended to improve GANs' training by adopting a smooth metric for measuring the distance between two probability distributions.
Off-axis detection and characterization of laser beams in the maritime atmosphere (2011)

Remote detection and characterization of laser beams propagating in maritime atmospheres is discussed. A model for off-axis scattered laser light based on Mie scattering from maritime aerosols is presented and compared with angle and time-resolved measurements from a pulsed laser source. We demonstrate that the direction of the source can be determined from the angle-resolved intensity and that the beam direction can be determined from arrival times of the scattered signals if the position of the laser source is known.

Temporal approach of the synthetic aperture imaging using Hadamard matrix (2008)

The synthetic aperture imaging is a very promising solution in the well-known compromise between contrast and frame rate. Indeed this method leads to the measurement of each transmitter/receiver impulse response of the system. From this fact, synthetic aperture imaging reach the transmit/receive focus imaging quality for the cost in frame rate of the number of antenna's elements. The main inconvenient of this method is the very low signal to noise ratio provided. Indeed, using only one transmitter per sequence leads to a very poor penetration. To correct this, a method using spatial Hadamard sequences has been introduced. For each of this Hadamard sequence, a Hadamard beam is generated in the medium. By a temporal approach, some interesting properties of those beams are highlighted and a method using those properties is proposed. Some experiments have been done using those properties and the results show an important improvement of the frame rate for a very small cost in contrast.
The Specificity of TIMP-2 for Matrix Metalloproteinases Can Be Modified by Single Amino Acid Mutations (1999)

Residues 1-127 of human TIMP-2 (N-TIMP-2), comprising three of the disulfide-bonded loops of the TIMP-2 molecule, is a discrete protein domain that folds independently of the C-terminal domain. This domain has been shown to be necessary and sufficient for metalloproteinase inhibition and contains the major sites of interaction with the catalytic N-terminal domain of active matrix metalloproteinases (MMPs). Residues identified as being involved in the interaction with MMPs by NMR chemical shift perturbation studies and TIMP/MMP crystal structures have been altered by site-directed mutagenesis. We show, by measurement of association rates and apparent inhibition constants, that the specificity of these N-TIMP-2 mutants for a range of MMPs can be altered by single site mutations in either the TIMP "ridge" (Cys1-Cys3 and Ser68-Cys72) or the flexible AB loop (Ser31-Ile41). This work demonstrates that it is possible to engineer TIMPs with altered specificity and suggests that this form of protein engineering may be useful in the treatment of diseases such as arthritis and cancer where the selective inhibition of key MMPs is desirable.
LQG AUTOPILOT AND RUDDER ROLL STABILIZATION CONTROL SYSTEM DESIGN (1987)

Roll stabilisation or reduction is to minimise the largest annular excursion of roll when a ship is subjected to wave disturbance. This is necessary to improve the comfort of personnel and the working efficiency of the crew on board. In ships which carry helicopters or vertical take-off and landing aircrafts, roll reduction enables the ship to operate in a more severe sea condition before the roll motion is excessive for the safe landing, taking-off and handling of these aircrafts.
