COMPLEX REACTION IN FLUIDIZED BEDS (1974)

Theoretical equations are derived to simulate the performance of fluidized-bed reactors in which complex reactions take place. As an example of complex reaction gasification is employed, where several simultaneous gas-solid as well as gas-gas reactions are involved. Some previously reported data on gasification are then explained by the proposed method.
MC(JBW): Simple but smart Monte Carlo algorithm for free energy simulations of multiconformational molecules (1998)

Many of the most common molecular simulation methods, including Monte Carlo (MC) and molecular or stochastic dynamics (MD or SD), have significant difficulties in sampling the space of molecular potential energy surfaces characterized by multiple conformational minima and significant energy barriers. In such cases improved sampling can be obtained by special techniques that lower such barriers or somehow direct search steps toward different low energy regions of space. We recently described a hybrid MC/SD algorithm [MC(JBW)/SD] incorporating such a technique that directed MC moves of selected torsion and bond angles toward known low energy regions of conformational space. Exploration of other degrees of freedom was left to the SD part of the hybrid algorithm. In the work described here, we develop a related but simpler simulation algorithm that uses only MC to sample all degrees of freedom (e.g., stretch, bend, and torsion). We term this algorithm MC(JBW). Using simulations on various model potential energy surfaces and on simple molecular systems (n-pentane, n-butane, and cyclohexane), MC(JBW) is shown to generate ensembles of states that are indistinguishable from the canonical ensembles generated by classical Metropolis MC in the limit of very long simulations. We further demonstrate the utility of MC(JBW) by evaluating the room temperature free energy differences between conformers of various substituted cyclohexanes and the larger ring hydrocarbons cycloheptane, cyclooctane, cyclononane, and cyclodecane. The results compare favorably with available experimental data and results from previously reported MC(JBW)/SD conformational free energy calculations. © 1998 John Wiley & Sons, Inc.

Au nom de l'individualité. Les formes contemporaines de la récidive (2004)

Dans un article publié dans le Bulletin de Criminologie, Claude Faugeron propose avec Jean-Michel Le Boulaire une interprétation assez provocatrice de la récidive. Celle-ci ne doit pas être assimilée, selon les auteurs, aux carences de la prison ou à un déficit de rétorsion. La récidive constituerait plutôt un indicateur des vertus de la sélection pénale. Lorsque le phénomène demeure anormalement bas, il y a lieu, selon eux, d'un voir un constat d'excès d'incarcération, consécutif à un défaut primaire des politiques sociales. Ce raisonnement semble applicable au cas des mineurs dits « mutirécidivistes » à quelques amendements près. En particulier, leur trajectoire traduit moins un défaut qu'un excès de la politique éducative. Surtout, elle marque l'influence grandissante que l'environnement, et la société locale notamment, exercent sur la justice des mineurs, au point que l'assistance éducative paraît échapper aujourd'hui au contrôle de l'autorité judicaire elle-même.
Complete Genome Sequence of Streptococcus pyogenes <i>emm28</i> Clinical Isolate M28PF1, Responsible for a Puerperal Fever (2015)

We report the sequence of the Streptococcus pyogenes emm28 strain M28PF1, isolated from a patient with postpartum endometritis. The M28 protein is smaller than that of MGAS6180 (NC_007296.1). Furthermore, the 1,896,976-bp-long chromosome presents, compared to that of MGAS6180, an inversion between the two comX genes.
First Deployment of Diminished Reality for Anatomy Education (2016)

Understanding the anatomy of the human body is vital for everyone working in the medical domain. Augmented reality (AR) systems for anatomy teaching, which display virtual information directly on top of a users' body, have proven to facilitate mental mapping compared to traditional teaching paradigms. In this paper, we explore the potential of diminished reality (DR) in the context of anatomy education. As a first necessary step to achieving a DR anatomy education system, parts of the human body have to be extracted and diminished from the video stream. Our system diminishes either the arm or head of the user by projecting a background image recovered using RGB-D cameras. Such a system, if combined with an accurate overlay of virtual counterparts, could potentially improve the learning effect by attracting the users' attention to the virtual information and improve visual perception by avoiding the well-known floating effect of AR.
Melt Electrowriting of Electroactive Poly(vinylidene difluoride) Fibers (2018)

Poly(vinylidene difluoride) (PVDF) has piezoelectric properties suitable for numerous applications such as flexible electronics, sensing and biomedical materials. In this study, individual fibers with diameters ranging from 17-55 μm were processed using melt electrowriting (MEW). Electroactive PVDF fibers can be fabricated via MEW, while the polymer could remain molten for up to ten hours without noticeable changes in the resulting fiber diameter. MEW processing parameters for PVDF were investigated, including applied voltage, pressure and temperature. A rapid fiber characterization methodology for MEW that automatically determines the fiber diameters from camera images taken of microscope slides was developed and validated. The outputs from this approach followed previous MEW processing trends already identified with different polymers, although overestimation of the < 25 micron fiber diameters was observed. The transformation of the PVDF crystalline phase to the electroactive beta-phase – without poling – was confirmed using piezo-force microscopy and revealed that the PVDF fibers possess piezoelectric responses showing d33~19 pm/V.
HEAT SENSITIVITY OF THE CORTICAL GRANULE PROTEASE FROM HAMSTER EGGS (1974)

Summary. Before fertilization, the protease present within the cortical granules of the hamster egg is relatively stable to heat. Once discharged into the medium, however, it is extremely heat sensitive, undergoing inactivation even at 37°C. Thus, body temperature would be expected to prevent the zona reaction of one egg from rendering neighbouring eggs infertile.
<title>Role of adsorbate structure in the dynamics of surface photodissociation</title> (1995)

Photofragments produced following 257 nm irradiation of physiosorbed methyl iodide on MgO(100) and TiO<SUB>2</SUB>(110) have been studied using resonantly enhanced multiphoton ionization coupled with time-of-flight mass spectrometry. The observed signal is associated with photofragment production from methyl iodide chromophores present in the near surface region. The dependence of the velocity distribution of methyl photofragments on ejection angle and polarization of the photolysis beam indicates that the multilayer film is composed primarily of an anti-parallel arrangement of methyl iodide molecules whose C-I bonds are aligned close to the surface normal. At submonolayer coverage on TiO<SUB>2</SUB> methyl iodide is predominantly in a parallel orientation with the iodine close to the surface and the methyl group pointing away from the surface.
Propriedades mecânicas de juntas soldadas com diferença de espessura pelo processo de soldagem por atrito linear com mistura em ligas de Al-Mg para aplicação na construção naval (2014)

The shipbuilding sector, as well as all modern transportation industries, is faced with demands for greater productivity while at the same time ensuring the manufacture of consistently high quality products, reducing levels of re-working, saving energy, and minimizing operational costs. Furthermore, it is imperative that new designs and all the stages of production comply with stringent environmental regulation. Within this context, the application of Friction Stir Welding (FSW) as a manufacturing process to weld Tailor Welded Blanks (TWB) for Al structures can contribute to the development of high speed craft and lightweight ships that are more fuel efficient, based on a high energetic efficient and environmental friendly welding process. In this work, the heterogeneous mechanical behavior of TWB joints welded by FSW was evaluated using quasi-static and cyclic loading, and the observed microstructural features were analyzed. The TWB joints were manufactured using dissimilar alloys and thicknesses (6 and 8mm) of particular interest in the shipbuilding sector (AA5083, AA5059 and AA6082). An evaluation of local constitutive properties in different regions through the TWB joint was performed by digital image correlation linked to the tensile test system. From the DIC data processing were generated stress concentrations diagrams and true stress-strain curves for several TWB subzones. The DIC methodology used as well as the accuracy of the proposed method are described in detail. The joints exhibited excellent mechanical properties approximately the same as those of the base metal for the joints manufactured with work hardened alloys (AA5059/AA5083) and 76% mechanical efficiency to those manufactured with the heat-treatable alloy (AA6082). The fatigue strength of the TWB joints were higher than the IIW references for welded structures in aluminum and the fracture mechanisms were characterized using SEM.
A case of highly diastereoselective addition to unsymmetrical ketones: <i>lk</i>‐addition of (2‐alkenyl)triphenoxytitanium derivatives (1982)

Abstract (2‐Butenyl)‐, (4‐methyl‐2‐pentenyl)‐, and (2‐heptenyl)triphenoxytitanium ( 2a – c ) add to dialkyl, alkyl aryl‐, and alkinyl aryl ketones to give high yields of tertiary homoallylic alcohols ( 5 – 12 ), which are diastereomerically enriched up to 98%. Configurational assignment by degradation of two of the products to olefins 15 and 18 ‐ through β‐hydroxy acids 13 and 16 and β‐lactones 14 and 17 ‐ leads to the proposal of a general mechanism and of a specification of the relative topicity lk of the process ( Scheme 5 ). The allylic Ti‐compounds 2 can serve as d 2 ‐reagents (see the d 2 ‐synthon II and the aldol‐type structures 1 ).
Current Rectification by Pauli Exclusion in a Weakly Coupled Double Quantum Dot System (2002)

We observe spin blockade due to Pauli exclusion in the tunneling characteristics of a coupled quantum dot system when two same-spin electrons occupy the lowest energy state in each dot. Spin blockade only occurs in one bias direction when there is asymmetry in the electron population of the two dots, leading to current rectification. We induce the collapse of the spin blockade by applying a magnetic field to open up a new spin-triplet current-carrying channel.
Hydrodynamic Characterization of Lupin Proteins:  Solubility, Intrinsic Viscosity, and Molar Mass (1996)

The solubility, intrinsic viscosity ([η]), and sedimentation behavior of a lupin protein system extracted from Lupinus luteus seeds have been determined. The results were compared with those published in the literature for soy proteins. The relationship between solubility and pH for the lupin protein isolate was similar to that reported in literature for soy isolates. The [η] of the lupin protein isolate was ∼7 mL/g. These values are comparable to those obtained by other authors for soy proteins. Sedimentation velocity studies suggested that there are three main globulins in lupin protein with sedimentation coefficients of 13, 7, and 2 S. The molar mass of the major lupin globulin (390 000 g/mol) was slightly higher than reported for the soy 11S globulin (340 000 g/mol), but the lupin 7S component gave a much smaller value (105 000 g/mol) than the soy 7S (180 000 g/mol). The consequences in thickening and thermal gelation properties of the lupin protein system are discussed. Keywords: Lupin proteins; solubility; intrinsic viscosity; molar mass

D'autres sont également présentés, comme les actionneurs à bobine mobile, les structures dentées ou les moteurs pas à pas hybrides.
Asymptomatic Diagnosis of Huanglongbing Disease Using Metalloporphyrin Functionalized Single-Walled Carbon Nanotubes Sensor Arrays (2020)

Porphyrins, with or without metal ions (MPs), have been explored and applied in optical and electrochemical sensor fields owing to their special physicochemical properties. The presence of four nitrogen atoms at the centers of porphyrins means that porphyrins chelate most metal ions, which changes the binding ability of MPs with gas molecules via non-specific binding. In this article, we report hybrid chemiresistor sensor arrays based on single-walled carbon nanotubes (SWNTs) non-covalently functionalized with six different MPs using the solvent casting technique. The characteristics of MP-SWNTs were investigated through various optical and electrochemical methods, including UV spectroscopy, Raman, atomic force microscopy, current-voltage (I-V), and field-effect transistor (FET) measurement. The proposed sensor arrays were employed to monitor the four VOCs (tetradecene, linalool, phenylacetaldehyde, and ethylhexanol) emitted by citrus trees infected with Huanglongbing (HLB), of which the contents changed dramatically at the asymptomatic stage. The sensitivity to VOCs could change significantly, exceeding the lower limits of the SWNT-based sensors. For qualitative and quantitative analysis of the four VOCs, the data collected by the sensor arrays were processed using different regression models including partial least squares (PLS) and an artificial neural network (ANN), which further offered a diagnostic basis for Huanglongbing disease at the asymptomatic stage.
Implantation induced optical losses in GaAs-AlGaAs distributed Bragg mirrors (2002)

We have examined the use of oxygen as an efficient species for creating current confinement in implanted VCSELs. Although oxygen isolation is a widely studied topic, it is rare to find in the literature the study of the optical damage caused by the oxygen implant. This optical damage is extremely consequential in VCSELs due to the weak gain guidance provided by the gain profile. In order to study the oxygen implantation induced optical damage, an n-type modulation doped, graded composition mirror was grown by low pressure MOCVD.
Über 1.3‐Dioxolane, I. Darstellung von 2‐Alkoxy‐1.3‐dioxolanen (1958)

Abstract Durch Umsetzung von 1.2‐Glykolen mit Orthoameisensäure‐trialkylestern in Gegenwart katalytischer Mengen konz. Schwefelsäure wurde eine Reihe von 2‐Alkoxy‐1.3‐dioxolanen dargestellt, in denen weiterhin durch Umsetzung mit prim. Alkoholen unter denselben Versuchsbedingungen die 2‐Alkoxygruppe ausgetauscht werden konnte. 1.3‐Glykole führten zur Bildung von 2‐Alkoxy‐1.3‐dioxanen, Brenzcatechin zu 2‐Alkoxy‐4.5‐benzo‐1.3‐dioxolan.

Limitation of the spread and impact of infectious coryza through the use of a continuous disinfection programme (2004)

The effect of a continuous disinfection programme, using the non-toxic disinfectant Virukill, in layers, on the spread and impact of infectious coryza, caused by Haemophilus paragallinarum was evaluated. In this experiment, both unvaccinated layers and layers vaccinated against infectious coryza were used. Duplicate smaller groups of vaccinated and unvaccinated chickens were challenged with different serovars of both NAD-dependent as well as NAD-independent isolates of Haemophilus paragallinarum. One group of chickens challenged with each of the different becterial serovars was treated with the continuous disinfection programme, while the other group remained as the untreated controls. The clinical signs of infectious coryza were evaluated over a period of 20 days in each group. The egg production over this period was also evaluated. It was found in all experimental challenges, that the severity of the symptoms was reduced in the birds receiving the continuous disinfection programme. The drop in egg production was also found to be less severe in the treated groups when compared to the untreated control groups. The duration of infection was found to be either unchanged, or shorter in the birds treated with the continuous disinfection programme. In none of the experimental challenges was the duration or expression of clinical signs of IC increased due to the continuous disinfection programme.
Chemisorption of In and Al on GaAs(110) (1994)

A quantum molecular dynamics study of the interface formation of the Al/GaAs(110) and In/GaAs(110) interfaces has been performed. It is found that, at very low coverages, both Al and In atoms chemisorb on threefold coordinated sites, bonded to two As atoms and one Ga atom. The metal atoms attract each other on the GaAs surface and tend to form islands. The electronic structure for one monolayer is found to be semiconducting for both In and Al. The results presented here are consistent with the temperature-dependent evolution of Fermi level from the very low metal coverage limit to the overlayer limit for the deposition of In and Al on GaAs(110).

GATA1-Mediated Megakaryocyte Differentiation and Growth Control Can Be Uncoupled and Mapped to Different Domains in GATA1 (2005)

The DNA-binding hemopoietic zinc finger transcription factor GATA1 promotes terminal megakaryocyte differentiation and restrains abnormal immature megakaryocyte expansion. How GATA1 coordinates these fundamental processes is unclear. Previous studies of synthetic and naturally occurring mutant GATA1 molecules demonstrate that DNA-binding and interaction with the essential GATA1 cofactor FOG-1 (via the N-terminal finger) are required for gene expression in terminally differentiating megakaryocytes and for platelet production. Moreover, acquired mutations deleting the N-terminal 84 amino acids are specifically detected in megakaryocytic leukemia in human Down syndrome patients. In this study, we have systematically dissected GATA1 domains required for platelet release and control of megakaryocyte growth by ectopically expressing modified GATA1 molecules in primary GATA1-deficient fetal megakaryocyte progenitors. In addition to DNA binding, distinct N-terminal regions, including residues in the first 84 amino acids, promote platelet release and restrict megakaryocyte growth. In contrast, abrogation of GATA1-FOG-1 interaction leads to loss of differentiation, but growth of blocked immature megakaryocytes is controlled. Thus, distinct GATA1 domains regulate terminal megakaryocyte gene expression leading to platelet release and restrain megakaryocyte growth, and these processes can be uncoupled.
Similarity matching for uncertain time series (2011)

In the last years there has been a considerable increase in the availability of continuous sensor measurements in a wide range of application domains, such as Location-Based Services (LBS), medical monitoring systems, manufacturing plants and engineering facilities to ensure efficiency, product quality and safety, hydrologic and geologic observing systems, pollution management, and others.
Normal Progression of Testicular Size in Boys with Idiopathic Short Stature and Isolated Growth Hormone Deficiency Treated with Growth Hormone: Experience from the KIGS (2002)

This analysis shows that GH treatment does not alter testicular growth in boys with ISS or IGHD. However, prospective controlled studies are needed to rule out moderate attenuating or stimulating effects.
Method of quantum computation with ``hot'' trapped ions (1998)

We present a novel method of performing quantum logic gates in trapped ion quantum computers which does not require the ions to be cooled down to their vibrational center of mass (CM) mode ground state. Our scheme employs adiabatic passages and the conditional phase shift first investigated by D'Helon and Milburn (C.~D'Helon and G.J.~Milburn, Phys. Rev. A {\bf 54}, 5141 (1996)).

Secure estimation for unstable systems (2016)

We assume that the states of an unstable dynamical system are encoded and sent to an estimator through an uncertain channel, which is a channel disturbing its inputs in a nonstochastic manner. The encoder's codeword is also fed into another uncertain channel, at whose output an eavesdropper is listening. The estimator should obtain a uniformly bounded system state estimation error, whereas the eavesdropper's information about the system states should be subject to a security constraint. We find a condition on the relation between the uncertain channel from encoder to estimator and the uncertain channel from encoder to eavesdropper which if satisfied allows for at least one of the two following security criteria to hold: The volume of the set of states possible acccording to the eavesdropper's information tends to infinity at exponential speed-by itself (strong security) or if divided by the volume of the set of states possible according to the estimator's information (weak security).
