Ramp-Rate Effects on Transient Enhanced Diffusion and Dopant Activation (2003)

Use of high ramp rates (>400°C/s) in rapid thermal annealing after ion implantation leads to experimentally observed improvements in junction depth and the reverse narrow-channel effect. However, a straightforward explanation for this effect has been lacking. Via modeling, we find that increasing the heating rate permits clusters with dissociation energies lower than the maximum of 3.5-3.7 eV to survive to higher temperatures. This improved survival delays the increase in Si interstitial concentrations near the top of an annealing spike, which decreases the profile spreading. © 2003 The Electrochemical Society.

Molecular biodiversity of arbuscular mycorrhizal fungi in trace metal‐polluted soils (2011)

We assessed the indigenous arbuscular mycorrhizal fungi (AMF) community structure from the roots and associated soil of Plantago major (plantain) plants growing on sites polluted with trace metals (TM) and on unpolluted sites. Uncontaminated and TM-contaminated sites containing As, Cd, Cu, Pb, Sn and Zn were selected based on a survey of the TM concentration in soils of community gardens in the City of Montréal. Total genomic DNA was extracted directly from these samples. PCR followed by denaturing gradient gel electrophoresis (PCR-DGGE), augmented by cloning and sequencing, as well as direct sequencing techniques, was all used to investigate AMF community structure. We found a decreased diversity of native AMF (assessed by the number of AMF ribotypes) in soils and plant roots harvested from TM-polluted soils compared with unpolluted soils. We also found that community structure was modified by TM contamination. Various species of Glomus, Scutellospora aurigloba and S. calospora were the most abundant ribotypes detected in unpolluted soil; ribotypes of G. etunicatum, G. irregulare/G. intraradices and G. viscosum were found in both polluted and unpolluted soils, while ribotypes of G. mosseae and Glomus spp. (B9 and B13) were dominant in TM-polluted soils. The predominance of G. mosseae in metal-polluted sites suggests the tolerance of this species to TM stress, as well as its potential use for phytoremediation. These data are relevant for our understanding of how AMF microbial communities respond to natural environments that contain a broad variety of toxic inorganic compounds and will substantially expand our knowledge of AMF ecology and biodiversity.
Analysis of Membrane Traffic in Polarized Epithelial Cells (2001)

Spatial asymmetry is fundamental to the structure and function of most eukaryotic cells. A basic aspect of this polarity is that the cell's plasma membrane is divided into discrete domains. The best studied and simplest example of this occurs in epithelial cells, which line exposed body surfaces. Epithelial cells use two pathways to send proteins to the cell surface. Newly made proteins can travel directly from the trans-Golgi network (TGN) to either the apical or basolateral surface. Alternatively, proteins can be sent to the basolateral surface and then endocytosed and transcytosed to the apical surface. Epithelial cells grown on porous filters adopt a typical polarized morphology; transfected epithelial cells can be used to biosynthetically characterize the trafficking patterns of a given protein. These cells can also be used to study delivery to a particular surface and to localize the protein by immunofluorescence.
Lab testing of new seismic sensor for defense and security applications (2004)

General Sensing Systems (GSS) has developed a sensor based on electrets material. Herein we describe the creation and lab testing of this very small and high performance seismic sensor intended for up-to-date security and military systems. This article delivers the first results of laboratory tests of this small size and extremely low cost new sensor. This new sensor was compared with the most popular geophones, the GS-14-L3 and GS-20DX geophones produced by Geo Space Corporation. The results show that the new, GSS sensor has an expanding frequency response range in both the low and high frequency areas. This is crucial for increased detection range of seismic-acoustic and hydro acoustic reconnaissance systems. The new, GSS sensor also has the highest sensitivity among all the compared geophones as well as a lower sensitivity threshold. When the amplitude of vibrations is very small, the GS-14-L3 and GS-20DX geophones, for example, miss signals-whereas the new sensor has a good response. Specifically, this performance characteristic of the new GSS sensor also allows the development of reconnaissance systems with a high detection range. Test results also show that the new sensor demonstrates good signal discrimination, ensuring efficient signal interpretation. In general, the results reported here show that the use of electrets materials enables the manufacture of very small and inexpensive seismic-acoustic and hydro acoustic sensors with improved performance characteristics.
Machinic Morphospaces: Biomimetic Design Strategies for the Computational Exploration of Robot Constraint Spaces for Wood Fabrication (2012)

The paper presents research into computational design processes that integrate not only criteria of physical producibility but also characteristics of design intelligence and performance. In the first part, the use of an industrial robotÂs design space for developing differentiated finger joint connections for planar sheets of plywood is being introduced. Subsequently, biomimetics is proposed as a filter for the possible geometric differentiations with respect performative capacities. The second part focuses on the integration of fabricational and biomimetic principles with structural and architectural demands, as well as by the development of a custom digital data structure for the fabrication of finger joint plate structures resulting in the construction of a full scale prototype. The paper concludes with evaluating the tolerances inherent in construction through 3D laser scan validation of the physical model.
Chromatography Applied to the Analyses of Petroleum Feedstocks and Products: A Brief Overview (2011)

Chromatography is a widely accepted and important analytical tool in petroanalyses. The technique provides composition of volatile and nonvolatile organic and certain inorganic compounds that affect feedstock catalytic processing and product quality. Analyses range from percentages to trace ppm and ppb concentration levels. A large number of ASTM methods apply chromatographic techniques.
The Plasmodial Surface Anion Channel: A Model Microbial Ion Channel and Target for Antimalarial Drug Development (2010)

Human malaria is a leading cause of morbidity and mortality worldwide; it is caused by 5 species of protozoan parasites from the genus Plasmodium. The most virulent of these species, P. falciparum, is estimated to affect more than 500 million people each year, resulting in > 1 million deaths annually. Estimates of the economic burden on developing countries are also astounding. Because there is not yet a globally useful vaccine, preventive measures such as insecticide-treated bednets [1] and treatment with drugs targeting parasite-specific activities are the mainstay of managing malaria in endemic countries. Because of evolving resistance to nearly all available antimalarials, there is a desperate need to develop new antimalarial drugs that target novel parasite activities.
<i>Ab Initio</i> Prediction of Atomic Location of Third Elements in B2-Type TiNi (2018)

Based on ab initio total energy calculations, we predict the atom location of the third element X (X = Sc, Ti, V, Cr, Mn, Fe, Co, Ni and Cu) in B2-type TiNi. The formation energy of Ti-substitutional X and Ni-substitutional X are estimated by using the Vienna Ab initio Simulation Package (VASP). It is found that Sc prefers the Ti-substitutional site and Cr, Mn, Fe and Co prefer the Ni-substitutional site. The location of V and Cu may depend on the composition of Ti and Ni. The chemical trend of the formation energy can be interpreted by the crystal orbital Hamiltonian population (COHP) analysis.
[True precocious puberty in non-tumor hydrocephalus. An analysis of 16 cases]. (1987)

True precocious puberty occurred in 16 children (15 girls and 1 boy) with non tumoral shunted hydrocephalus at a mean age of 6.8 years. They had mild clinical manifestations of precocious puberty, and the other pituitary functions were found to be normal. Except for one child, precocious puberty did not correlate with raised intracranial pressure or lack of cerebral drainage by the shunt. Growth was the main concern in this group as the predicted height fell at a mean value of 1.7 SD below the parental target height, and even more in children with myelomeningocele. This growth retardation is due to an early progression of bone age observed even prior to the appearance of breast or pubic hair. Therefore we suggest that these children might benefit from early treatment by an LHRH analogue as soon as precocious puberty occurs.
Coherent terahertz emission from coupled quantum wells with exciton effects (1994)

We have developed a theoretical model for investigating the recent observation of terahertz electromagnetic pulse emission from GaAs–Ga0.8Al0.2As asymmetric coupled-quantum-well structures. We use a multisubband model that takes into account Coulomb interactions among all electrons and holes, particularly the exciton effects. The calculations indicate that the terahertz emission originates from the quantum beat between heavy-hole excitons in the narrow well and shifts to two resonantly coupled exciton states in the coupled quantum wells and later to heavy-hole excitons in the wide well as the applied dc field is increased. Furthermore, exciton, interband, and intersubband dephasing times determine the characteristics of the radiation fields. The theoretical results are in good agreement with those of previous experiments.

Sludge Retention Times Distribution in Clarifier: A Key Point for Population Dynamic and Nutrients Removal Control (1994)

Experiments were carried out on full scale clarifiers. Two types of clarifiers were studied, circular scraper-type and radial suction tubes clarifiers. Sludge tracing experiments were made with radioactive gold. For the first type of clarifier, the results obtained show a short circuit concerning 10 to 30% of the sludge and a large distribution of the remaining sludge arrivals materialized by a succession of peaks that appear with increasing delay. Depending on cases studied, 40 to 50% of the sludge remained more than 5 hours in the system. For the suction clarifier, a perfect sludge distribution with time was observed for thin sludge bed (90% of the sludge recycled within 2 hours), but this result is rapidly affected by an increase of the sludge bed depth (60% within 5 hours).
Formation of Aromatic Rings through Enamine Annulation (2000)

Condensation of pyrrolidine enamine of ketones with 1, 4-diacetoxy-2-butanone provides a new, concise synthetic route to substituted benzenes, dihydroindenes, tetrahydronaphthalenes, and di- and octahydrophenanthrenes. The reaction produced modest yields with regiocontrol of the secondary amine substituent.
Transverse acoustic modes in TTF-TCNQ (tetrathiafulvalene-tetracyanoquinodimethane) (1977)

The transverse acoustic modes [$\mathrm{TA}({a}^{*})$] of tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ) propagating along the chain direction (${b}^{*}$) and polarized along ${\stackrel{\ensuremath{\rightarrow}}{\mathrm{a}}}^{*}$ are studied between room temperature and 60 K. No anomalous behavior is observed at $q=2{k}_{F}$ in the temperature region studied. These results, taken in conjunction with other neutron and x-ray experiments, show that the Kohn anomaly in TTF-TCNQ occurs in the $\mathrm{TA}({c}^{*})$ branch which is the transverse branch polarized principally along ${c}^{*}$.
An Orientation Measuring System Suitable for Routine Uses Made by the Fusion of a 3D Gyroscope and a Magnetic Tracker (2007)

Many studies have shown the efficacy of orientation and three-dimensional joint angle measurement for patient evaluation or rehabilitation purposes. But currently, the use of these systems for routine practice is questionable. The commercially available devices are generally too expensive and complicated-to-use. This study proposed the fusion between two affordable types of orientation measuring systems, which used separately couldn't satisfy the health professionals' needs. One was a portable magnetic tracker limited in accuracy, sampling frequency and possibly distorted. The other was triplets of gyroscopes limited by their bias, which generates orientation drift after integration. The fusion algorithm presented here relay on two cascaded complementary Kalman filters to estimate the bias of the gyroscopes and to provide accurate and high frequency orientation even during distortion periods. This system was assessed during treadmill walking and reported good performances.
How to Select Cancer Cells with the Proper Qualifications (1971)

A few years ago Todaro and Green1 developed a cell-culture line of mouse fibroblasts that exhibited an unusual degree of growth control. This line, called the 3T3 mouse line, consists of fibroblasts or fibroblast-like cells that grow as a monolayer. When the culture reaches a certain density and the cells are confluent or near confluent, cellular proliferation ceases almost completely. To be sure, this growth control is only relative since, by simply increasing the concentration of serum, these cells continue to proliferate and divide even after they have reached confluence.2 However, under constant culture conditions, constant frequency of medium changes . . .
Heterogeneous FPGA-based System for Real-Time Drowsiness Detection (2022)

Drowsiness detection is a key feature in modern Advanced Driver Assistance Systems (ADAS). State-of-the-art approaches rely on machine learning techniques and neural networks to monitor unusual movements of the head and eyes activities. Unfortunately, due to their computationally intensive operations, integrating such algorithms in real-time and low-power operating scenarios, like auto-motive applications, is still quite challenging. This paper proposes an efficient hardware architecture for real-time drowsiness detection based on monitoring the driver’s eye blinking behaviour through the PERcentage of eye CLOSure (PERCLOS) metric. Experimental results obtained on the Xilinx Zynq XC7Z020 FPGA SoC show that the proposed system is up to 33.3 times faster and 2.6 times less area consuming than state-of-the-art competitors.

Spin properties of quantum wells with magnetic barriers. II. Inverted band ordering and spin polarized interface states (2002)

The electronic band-edge spectrum of the interface states in the magnetic semiconductor quantum wells based on narrow-gap semiconductors with mutually inverted band arrangement is studied within the envelope-function formalism. Interface states are shown to appear in these structures in the case of overlapping bulk bands of the constituents. The hybridization between the bare $\mathrm{sp}$-electron states and the d states of the Mn atoms leads to spin splitting. The spin-splitting effect of the interface states as a function of external magnetic field, well width, band offsets, and fraction of the magnetic atoms, is studied. One essential result is that one can design a structure where the states localized at the interfaces only have one spin direction. The results give evidence of the perspective for using the magnetic semiconductor structures in spin electronics.
En ung mann med mononukleose og hevelse over høyre øye (2011)

Treatment of acute infections in the upper airways comprises a significant part of direct healthcare expenditure and is a challenge for healthcare professionals. In Norway, 11,495 hospitalized days were recorded for acute infections (influenza and pneumonia excluded) in the upper airways in 2008. Acute bacterial rhinosinusitis (ABRS) is defined as inflammation of the nose and the paranasal sinuses characterized by both 1): symptoms of nasal blockage/obstruction/congestion or nasal discharge, and/or facial pain/pressure and 2): endoscopic signs of mucopurulent discharge from middle meatus and/or CT changes within the osteomeatal complex/sinuses. After 12 weeks of symptoms the definition changes to chronic rhinosinusitis. With antibiotic treatment of complicated ABRS we see fewer severe complications, but they still occur. Due to anatomical proximity of the orbit and intracranial structures a localized spread of the infection is especially unfortunate and potentially dangerous. We present a case report (with pan sinusitis and grave local complications) from the ear, nose and throat department in St. Olav's University Hospital in Trondheim, Norway.
Frequency-Modulated Non-contact Atomic Force Microscopy Study of Heat-Treated Oxide Surface with Organic Molecules (2006)

The morphology of the (100) surface of single-crystalline SrTiO3 was studied using frequency-modulated non-contact atomic force microscopy (FM-NCAFM) at a temperature of 100 K. After appropriate etching and heating treatments, unit-cell steps with atomically flat terraces have been successfully obtained. These surfaces were found to be quite stable under ultrahigh vacuum conditions as long as the temperature was maintained below 600 K. A specially tailored porphyrin-based molecule with carboxyphenyl substituent was dispersed on the substrates, and strong suppression of their mobility on the surface was found by FM-NCAFM observations.
Journey Toward High Reliability: A Comprehensive Safety Program to Improve Quality of Care and Safety Culture in a Large, Multisite Radiation Oncology Department (2016)

Our journey toward becoming an HRO has led to the development of a robust SC through a comprehensive safety framework. Our multifaceted initiatives, focusing on culture and system changes, can be successfully implemented in a large academic radiation oncology department to yield measurable improvements in SC and outcomes.
Determination of yttrium iron garnet superexchange parameters as a function of oxygen and cation stoichiometry (2010)

In this work, we describe the consequences of oxygen and metal-ion deficiency for the magnetic properties of a magnetic oxide in bulk and thin-film form. The influence of the off stoichiometry on valence of the iron atoms and the local structural configuration of these atoms is investigated in correlation with the magnetic Curie temperatures and the associated microscopic parameters, such as the exchange integrals. Combining both structural information obtained by x-ray absorption spectroscopy at $\text{Fe}\text{ }K$ edge and exchange integrals as determined from temperature-resolved magneto-optical magnetometry, we show that the electron-transfer integrals, underlying the superexchange interaction, control the global dependence of the Curie temperature on stoichiometry as should be expected. The determination of the electron-transfer integrals allows also the confirmation that metal-ion deficiencies in off-stoichiometric yttrium iron garnet (OS YIG) films lead to a significant increase in the magnetization (as observed experimentally). That can only be explained when considering a preferential site occupation of the iron vacancies on octahedral sites in agreement with our earlier work on OS YIG films [Y. Dumont et al., Phys. Rev. B 76, 6 (2007)]. Furthermore, the combination of the experimentally determined iron valence with the ${\text{Fe}}_{a}{\text{-O-Fe}}_{d}$ bonding angle and the exchange integrals allows for the direct determination of the crystal electric field parameter and the Coulomb repulsion energy as a function of the stoichiometry of the YIG films.
