[General practitioner and respiratory medicine specialist. A survey on the management of the asthmatic patient]. (2003)

The relationship between the general practitioner (GP) and the respiratory medicine physician specialist in the management of the asthmatic patients was examined. Two-hundred sixty -two GPs from Brescia and province were enrolled into the study and underwent an appropriate questionnaire, focusing the survey on three aspects: the relationship among GP-respiratory medicine physician specialist and asthma patients, the training of GP, the appraisal of the socio-economic aspects of the management of bronchial asthma. The results have shown the requirement of a GP-respiratory medicine physician specialist relationship founded on the exchange of information and experiences, rather then of synthetic diagnoses and therapeutic directions, and the opportunity to establish outpatients' departments dedicated to the management of the asthmatic patients. Moreover, it has been shown an inadequate application of international guidelines and a not full appraisal of the socio-economic aspects of the management of the asthmatic patients.
Biochemical Characteristics of Typhus Group Rickettsiae with Special Attention to the Rickettsia prowazekii Strains Isolated from Flying Squirrels (1978)

Six strains of Rickettsia prowazekii, two derived from human infections and four isolated from flying squirrels, two strains of R. typhi, and the single available strain of R. canada, were characterized by several biochemical procedures. The electrophoretic patterns on polyacrylamide gels of rickettsial proteins solubilized by sodium dodecyl sulfate revealed several species differences, but strains of the same species appeared to have identical patterns. Cytoplasmic fractions of the rickettsiae were examined for enzymatic activities and for polyacrylamide gel isoelectric focusing patterns. Some species differences were encountered in the activities or ratios of activities of glutamate-oxaloacetate transaminase, glutamate dehydrogenase, and malate dehydrogenase. When polyacrylamide gels were stained for malate dehydrogenase after electrophoresis, a single band became apparent with single extracts or mixtures of two strains of R. prowazekii, but two bands were seen with mixtures of a strain of R. prowazekii and one of R. typhi. The isoelectric focusing patterns of the soluble proteins revealed numerous species differences, especially between R. canada and the other two species, and a few differences among the strains of R. prowazekii. The patterns of the two human strains, Breinl and E(R), differed in at least one location, and both differed from the flying squirrel strains in the displacement of one band. One of the flying squirrel strains, GvF-16, contained a protein band not seen in the other five strains. Despite these minor differences, a striking similarity was revealed by all the biochemical tests performed between the R. prowazekii strains of human and flying squirrel origin.

A digital instrument for the calibration of current-to-voltage transducers (1998)

Modern instrumentation for the monitoring of electrical power systems is based on digital signal processing (DSP) techniques. If suitable design choices are made, the overall accuracy of this kind of instrumentation basically depends on the signal conditioning circuits. They have outputs proportional to the input to drive the A/D converters and are very often based on instrument transformers to ensure the isolation between the instrumentation and the monitored power system. This paper presents a lab prototype of a digital instrument for the calibration of current-to-voltage transducers (CVT's) and discusses its performance. The results of calibration tests performed on some commercial active and passive CVT's are also reported.
Novel inspection technology for half pitch 55 nm and below (2005)

In the automatic macro inspection, a diffraction light method is very effective. However, this method needs a shorter wavelength illumination for finer wafer patterns. A wavelength of 193 nm will be needed for half pitch 55 nm. Light source and optics for such shorter wavelength is large and expensive, and chemical clean environment is needed. Therefore, the equipment size and costs will increase dramatically. In order to solve this problem and to comply with the process of half pitch 55 nm and below, we have developed the breakthrough technology. The key is the image of polarization fluctuation caused by a wafer pattern structure. The polarized light is affected by the variation of the wafer pattern structure due to a dose or focus shift. The new technology converts the polarization fluctuation into the gray level of the image. At a result, the sensitivity for the dose or focus shift was enough to detect process errors.
La formacion del futuro profesor de matematicas y la construccion de la identidad disciplinar (2019)

Se reportan los avances de investigacion acerca de la formacion inicial de estudiantes de pedagogia en matematicas. En este escenario se ha identificado una problematica con relacion a como estos estudiantes, de formacion inicial, se adhieren a lo que desde la teoria socioepistemologica se ha conceptualizado como discurso Matematico Escolar. En terminos genericos, esta problematica radica en que ese estudiante ha sido excluido de la construccion social del conocimiento matematico en su formacion inicial. Con el proposito de contrapesar dicha problematica se propone que en esa formacion inicial se debe promover una matematica escolar que valore los usos y significados del conocimiento matematico del que aprende, asi como construir una horizontalidad reciproca entre la matematica escolar y la realidad de la gente. En este contexto, se destaca la identidad disciplinar y la funcion del docente como elementos que son opacados por la problematica identificada.
Interactive geometry remeshing (2002)

We present a novel technique, both flexible and efficient, for interactive remeshing of irregular geometry. First, the original (arbitrary genus) mesh is substituted by a series of 2D maps in parameter space. Using these maps, our algorithm is then able to take advantage of established signal processing and halftoning tools that offer real-time interaction and intricate control. The user can easily combine these maps to create a control map --- a map which controls the sampling density over the surface patch. This map is then sampled at interactive rates allowing the user to easily design a tailored resampling. Once this sampling is complete, a Delaunay triangulation and fast optimization are performed to perfect the final mesh.As a result, our remeshing technique is extremely versatile and general, being able to produce arbitrarily complex meshes with a variety of properties including: uniformity, regularity, semi-regularity, curvature sensitive resampling, and feature preservation. We provide a high level of control over the sampling distribution allowing the user to interactively custom design the mesh based on their requirements thereby increasing their productivity in creating a wide variety of meshes.
Three-Coordinate Aluminum in Zeolites Observed with In situ X-ray Absorption Near-Edge Spectroscopy at the Al K-Edge:  Flexibility of Aluminum Coordinations in Zeolites (2003)

Application of in situ X-ray absorption near-edge spectroscopy (XANES) at the Al K-edge provides unique insight into the flexibilty of the aluminum coordinations in zeolites as a function of treatment or during true reaction conditions. A unique, previously not observed, pre-edge feature is detected in zeolites H-Mordenite and steamed and unsteamed H-Beta at temperatures above 675 K. Spectra simulations using the full multiple scattering code Feff8 identify the unique pre-edge feature as three-coordinate aluminum. The amount of three-fold coordinated aluminum is a function of temperature and pretreatment of a zeolite: a steamed zeolite Beta contains more three-coordinate aluminum than an unsteamed sample. No clear differences between zeolites H-Mordenite and H-Beta were observed. Octahedrally coordinated aluminum forms in zeolites H-Mordenite and H-Beta at room temperature in a stream of wet helium. This octahedrally coordinated aluminum is unstable at temperatures higher than 395 K, where it quantitatively reverts to the tetrahedral coordination.
Detection of Abnormal Data of Gateway Energy Meter Based on User Dynamic Behavior Mining (2020)

Since the quality of measuring data of gateway energy meter has significant impacts on the fairness and impartiality of trade settlement, detection of abnormal data is of great importance. However, recent related researches of meter measuring data focus on the abnormal causes and the design of an on-line monitoring system, the value of data mining itself is ignored. For this reason, this paper proposes a method of detecting abnormal data in the gateway energy meter based on user dynamic behavior mining. According to the regularity of power load data, a detection method for random abnormal points based on time series decomposition and autocorrelation analysis is proposed. At the same time, for the continuous abnormal situation of the data caused by the user’s power theft behavior that the power grid company is concerned about, the line loss rate and the continuous decline trend of the power consumption are extracted. Then, a detection model is established to realize the detection of abnormal data in the gateway energy meter. Finally, the validity of this method is verified based on the measured data of the power grid. The result proves that the proposed method can accurately detect the abnormal data of the gateway energy meter and meet the needs of engineering practice.
Harnessing biological applications of quantum materials: opportunities and precautions (2020)

Biological applications of quantum materials require an intimate material-biology interface. Thus, parallel toxicological studies should be performed so that biological interactions can be considered as a separate and critical performance attribute.
Endoscopie bronchique assistée par ordinateur : résolution multi-niveaux d'un problème d'optimisation scène/modèle (1997)

Cette these decrit des travaux relevant du domaine de la vision par ordinateur, motives par une application medicale novatrice : l'endoscopie bronchique assistee par ordinateur. Ce projet consiste en une fusion de deux types de donnees medicales : d'une part, un examen scanner pre-operatoire de la cage thoracique (mettant en evidence une lesion suspecte a ponctionner), et d'autre part des images endoscopiques per-operatoires, acquises lors d'une exploration de l'interieur de l'arbre bronchique. Ceci permet de fournir une assistance pour une ponction a travers la paroi bronchique. Les problemes poses par cette application de realite augmentee se situent dans le cadre classique d'une analyse scene/modele : il s'agit de mettre en correspondance une scene (une vue endoscopique 2D) avec un modele (les coupes scanner 3D), sans utiliser de localisateur externe. Pour cela, des methodes originales de traitement d'images sont proposees ; elles permettent de resoudre les problemes poses par la segmentation, le recalage et la reconstruction 3D des images a analyser. Ces methodes utilisent, en particulier, des outils de morphologie mathematique, un algorithme de recalage sans fonctionnelle (par « demons ») et un « model-based shape-from-shading ». De plus, face aux difficultes specifiques soulevees par les donnees a traiter, une approche multi-niveaux est introduite dans cette these. Cette strategie tire profit, pour chaque niveau d'analyse, du maximum d'informations a priori disponibles. Finalement, les resultats presentes montrent qu'il est possible de localiser precisement la position de l'endoscope par rapport aux donnees scanner. Ainsi, l'ordinateur est capable de calculer, quasiment en temps reel, la vue endoscopique virtuelle qui correspond a la vue reelle du moment.
Crystallization and preliminary crystallographic studies of pyridoxal kinase from sheep brain (2002)

Pyridoxal kinase (ATP:pyridoxal 5'-phosphotransferase; EC 2.7.1.35) is a key enzyme in the transformation of vitamin B(6) to pyridoxal-5'-phosphate. Pyridoxal-5'-phosphate is the crucial cofactor required by numerous enzymes involved in the metabolism of amino acids and the synthesis of many neurotransmitters. Pyridoxal kinase from sheep brain was crystallized in an orthorhombic form using the hanging-drop vapour-diffusion method with sodium citrate as the precipitant. The crystals belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 59.8, b = 94.4, c = 128.2 A, and diffract to a resolution of 2.1 A. Crystals were transferred into a soaking liquid without citrate and two heavy-atom derivatives were prepared.
Risk factors and preventive measures for encapsulating peritoneal sclerosis--Jikei experience 2002. (2002)

A growing incidence of encapsulating peritoneal sclerosis (EPS) has been reported recently in Japan, and it is now urgent to establish preventive measures against EPS development. In the present paper, we describe our observational results regarding the risk of EPS development and the characteristic features of patients with EPS, in terms of peritoneal morphology and peritoneal function as determined by peritoneal equilibration test. The ongoing working protocol for EPS prevention at Jikei University Hospital is also discussed. Our findings have revealed that long-term continuous ambulatory peritoneal dialysis (CAPD) is a risk factor for EPS development after transfer to hemodialysis from peritoneal dialysis (PD), and that, in most patients with EPS, peritoneal function is characterized by a longstanding high-transport state. The striking alterations in peritoneal morphology between patients with EPS and those with simple long-term CAPD hyperplasia include, in EPS patients, a prominent thickening of the collagenous layer of the peritoneum with neoangiogenesis and myofibroblastic transformation. Based on our findings, we established a withdrawal protocol for long-term CAPD patients, with the goal of preventing EPS. Those who have been on PD treatment for more than 72 months with high-transport state are candidates for withdrawal from PD, with performance of peritoneal lavage thereafter for a certain period of time. The clinical benefit of post-PD lavage has not yet been determined; however, the maneuver could be precluded in patients at low risk of EPS, because it was found that some patients can recover to average transport state during the period of PD withdrawal. Patients who remain high transporters with inflammatory reaction might require pharmacologic intervention, including prednisolone therapy. Further observations are required to validate our approach.
The OP9-DL1 System: Generation of T-Lymphocytes from Embryonic or Hematopoietic Stem Cells In Vitro (2009)

INTRODUCTION Differentiation of mouse embryonic stem cells (ESCs) or hematopoietic stem cells (HSCs) from fetal liver or bone marrow into T-lymphocytes can be achieved in vitro with the support of OP9-DL1 cells, a bone-marrow-derived stromal cell line that ectopically expresses the Notch ligand, Delta-like 1 (Dll1). This approach provides a simple, versatile, and efficient culture system that allows for the commitment, differentiation, and proliferation of T-lineage cells from different sources of stem cells. This article contains a series of protocols, the first of which describes the establishment, maintenance, and storage of OP9 and OP9-DL1 cells. Subsequent protocols detail how to co-culture the OP9 and OP9-DL1 cells with either ESCs or HSCs from fetal liver or bone marrow, leading to in vitro differentiation of the stem cells into lymphocytes.
Reduction of inflammatory cytokine expression and oxidative damage by erythropoietin in chronic heart failure (2006)

It thus appears that Stat-mediated reduction of inflammation and cytokine production and Akt-mediated attenuation of oxidative stress accompany the beneficial effects of late treatment with EPO on chronic post-MI heart failure.
Phosphorus Molecules on Ge(001): A Playground for Controlled n-Doping of Germanium at High Densities (2013)

The achievement of controlled high n-type doping in Ge will enable the fabrication of a number of innovative nanoelectronic and photonic devices. In this work, we present a combined scanning tunneling microscopy, secondary ions mass spectrometry, and magnetotransport study to understand the atomistic doping process of Ge by P2 molecules. Harnessing the one-dimer footprint of P2 molecules on the Ge(001) surface, we achieved the incorporation of a full P monolayer in Ge using a relatively low process temperature. The consequent formation of P-P dimers, however, limits electrical activation above a critical donor density corresponding to P-P spacing of less than a single dimer row. With this insight, tuning of doping parameters allows us to repeatedly stack such 2D P layers to achieve 3D electron densities up to ∼2 × 10(20) cm(-3).

Identification of anopd(Organophosphate Degradation) Gene in anAgrobacteriumIsolate (2002)

We isolated a bacterial strain, Agrobacterium radiobacter P230, which can hydrolyze a wide range of organophosphate (OP) insecticides. A gene encoding a protein involved in OP hydrolysis was cloned from A. radiobacter P230 and sequenced. This gene (called opdA) had sequence similarity to opd, a gene previously shown to encode an OP-hydrolyzing enzyme in Flavobacterium sp. strain ATCC 27551 and Brevundimonas diminuta MG. Insertional mutation of the opdA gene produced a strain lacking the ability to hydrolyze OPs, suggesting that this is the only gene encoding an OP-hydrolyzing enzyme in A. radiobacter P230. The OPH and OpdA proteins, encoded by opd and opdA, respectively, were overexpressed and purified as maltose-binding proteins, and the maltose-binding protein moiety was cleaved and removed. Neither protein was able to hydrolyze the aliphatic OP malathion. The kinetics of the two proteins for diethyl OPs were comparable. For dimethyl OPs, OpdA had a higher k(cat) than OPH. It was also capable of hydrolyzing the dimethyl OPs phosmet and fenthion, which were not hydrolyzed at detectable levels by OPH.
Three-dimensional echocardiography-based analysis of right ventricular shape in pulmonary arterial hypertension (2015)

STATUS OF THE EXPLORATION OF AN ALTERNATIVE CLIC FIRST ENERGY STAGE BASED ON KLYSTRONS (2013)

The Compact Linear Collider is based on a two-beam scheme to accelerate the main, colliding beams. This scheme allows very high centre-of-mass energies to be reached. At low collision energies the main beams could be accelerated by powering the X-band accelerating structures with klystrons instead of the two-beam scheme. We explore this option and indicate the parameters such a machine might have and present the outline of a design.
A novel approach for flip chip solder joint quality inspection: laser ultrasound and interferometric system (2001)

A novel, noncontact, nondestructive approach for flip chip solder joint quality inspection is presented. In this technique, a pulsed laser generates ultrasound on the chip's surface, exciting the whole chip into a vibration motion. An interferometer was used to measure the vibration displacement of the chip's surface. Because changes in solder joint quality produce a different vibration response, a value, "error ratio," is used to measure the difference between a good chip and a chip with defects. An automatic signal-processing algorithm to calculate the error ratio was developed and implemented, as well as a frequency analysis algorithm. The inspection system was characterized, and results are presented for two cases of flip chips with missing solder balls. Results indicate that a laser ultrasonic/interferometeric system offers great promise for solder bump inspection in flip chip, BGA, chip scale, and micro BGA packages.
Alkyl Aryl Ether Bond Formation with PhenoFluor (2015)

Abstract An alkyl aryl ether bond formation reaction between phenols and primary and secondary alcohols with PhenoFluor has been developed. The reaction features a broad substrate scope and tolerates many functional groups, and substrates that are challenging for more conventional ether bond forming processes may be coupled. A preliminary mechanistic study indicates reactivity distinct from conventional ether bond formation.

A Fast Modular Method for True Variation-Aware Separatrix Tracing in Nanoscaled SRAMs (2014)

As memory density continues to grow in modern systems, accurate analysis of static RAM (SRAM) stability is increasingly important to ensure high yields. Traditional static noise margin metrics fail to capture the dynamic characteristics of SRAM behavior, leading to expensive over design and disastrous under design. One of the central components of more accurate dynamic stability analysis is the separatrix; however, its straightforward extraction is extremely time-consuming, and efficient methods are either nonaccurate or extremely difficult to implement. In this paper, we propose a novel algorithm for fast separatrix tracing of any given SRAM topology, designed with industry standard transistor models in nanoscaled technologies. The proposed algorithm is applied to both standard 6T SRAM bitcells, as well as previously proposed alternative subthreshold bitcells, providing up to three orders-of-magnitude speedup, as compared with brute force methods. In addition, for the first time, statistical Monte Carlo separatrix distributions are plotted.
