Quantifying Main Trends in Lysozyme Nucleation:  The Effect of Precipitant Concentration, Supersaturation, and Impurities (2001)

Full factorial experimental design incorporating multilinear regression analysis of the experimental data allows quick identification of main trends and effects using a limited number of experiments. In this study, we illustrate the usefulness of these techniques in macromolecule crystallization studies, by employing them to identify the effect of precipitant concentration, supersaturation, and the presence of an impurity, the physiological lysozyme dimer, on the nucleation and dimensions of chicken egg white lysozyme crystals. Decreasing precipitant concentration, increasing supersaturation, and increasing impurity were found to increase crystal numbers. The crystal axial ratio decreased with increasing precipitant concentration, independent of impurity.
The Joint Exploration Model (JEM) for Video Compression With Capability Beyond HEVC (2019)

This paper provides an overview of the coding algorithms of the Joint Exploration Model (JEM) for video compression with capability beyond HEVC, which was developed by the Joint Video Exploration Team (JVET) of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The goal of the JEM development and experimentation was to provide evidence that sufficient coding efficiency improvement over the High Efficiency Video Coding (HEVC) standard can be achieved, which would justify the need for a new video coding standard with a compression capability significantly exceeding that of HEVC. The development of the JEM provided an ability to conduct studies toward that goal in a verifiable and collaborative manner and led to the launching of the project to develop the new Versatile Video Coding (VVC) standard. Objective metric gains exceeding 30% were measured for most of the tested high-resolution video content that represents current demanding new applications, and subjective testing using human observers showed even more benefit.
Extending SQL with general transitive closure and extreme value selections (1990)

Many recursive query processing applications are still poorly supported, partly because implementations of general recursive capabilities are inefficient and hard to understand for users, partly because the approaches do not integrate well with existing query languages. An extension is proposed of the database language SQL for the processing of recursive structures. The new constructs are integrated in the view definition mechanism of SQL. Therefore, users with knowledge of SQL can take advantage of the increased functionally without learning a new language. The construct is based on a generalization of transitive closure and is formally defined. Because of the importance of extreme value sections, special constructs are introduced for the selection of tuples with minimal or maximal values in some attributes. Applying these selections on recursively defined views constitutes nonlinear recursion. By the introduction of special constructs for these selections, dealing with general nonlinear recursion can be avoided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Structural Insights into the Interaction of Cytochrome P450 3A4 with Suicide Substrates: Mibefradil, Azamulin and 6′,7′-Dihydroxybergamottin (2019)

Human cytochrome P450 3A4 (CYP3A4) is the most important drug-metabolizing enzyme. Some drugs and natural compounds can act as suicide (mechanism-based) inactivators of CYP3A4, leading to unanticipated drug-drug interactions, toxicity and therapeutic failures. Despite significant clinical and toxicological implications, the mechanism-based inactivation remains incompletely understood. This study provides the first direct insights into the interaction of CYP3A4 with three suicide substrates: mibefradil, an antihypertensive drug quickly withdrawn from the market; a semi-synthetic antibiotic azamulin; and a natural furanocoumarin, 6',7'-dihydroxybergamottin. Novel structural findings help better understand the suicide substrate binding and inhibitory mechanism, and can be used to improve the predictability of the binding ability, metabolic sites and inhibitory/inactivation potential of newly developed drugs and other chemicals relevant to public health.
A prototype of a fast cycle adsorption refrigerator utilizing a novel carbon—aluminium laminate (2000)

A laboratory prototype of a fast cycle adsorption refrigerator is presented: it uses a monolithic carbon-aluminium laminate adsorbent and ammonia refrigerant. The system has a high effective thermal conductivity and density bed and is powered by heat and designed to provide a specific cooling power up to 1 kW/kg adsorbent. There are two generators and each one consists of a tubular stainless steel shell containing a laminate of activated carbon discs and aluminium fins formed in situ. The full unit is designed for a power input up to 10 kW and a cooling power up to 3 kW. Preliminary results of the performance are presented and allow assessment of the intensification of heat transfer within the bed. At specific working conditions (evaporating and condensing temperatures, 7.5 and 32°C respectively; generating temperature, 140°C; half-cycle time, 620 s), the results have demonstrated the intensification of heat transfer within the generator through temperature and pressure profiles during the cycles. With an intrinsic heating power input of about 1.130 kW, the refrigerator produces continuously about 0.500 kW of cooling that corresponds to a specific cooling power of 0.180 kW/kg. The cooling coefficient of performance (COP) is about 0.44.
Monoterpene persistence in the sapwood and heartwood of longleaf pine stumps: assessment of differences in composition and stability under field conditions (2009)

Monoterpenes in exudates, phloem, and sapwood have received considerable attention relative to the active defenses of pine trees. However, little is known about the composition and function of the heartwood monoterpenes. To address this deficiency, monoterpene contents and relative compositions were determined for sapwood and heartwood samples from longleaf pine ( Pinus palustris Mill.) stumps monitored in the field for a 1 year period postharvest. Gas chromatography – mass spectrometry analysis of sapwood and heartwood sample extracts showed the total monoterpene contents for both declined at essentially the same rate. For sapwood, α-pinene continued to comprise about 75% of all compounds detected, while the proportion of β-pinene declined with time (15%–7%). For the heartwood, lower proportions of both α- and β-pinenes (64% and 10%, respectively) were offset by higher proportions of other monoterpenes (e.g., limonene, α-terpineol, borneol). The low proportion of β-pinene in very old turpentine and lightwood stump samples further suggested the lower stability of this particular monoterpene. While it has not been specifically demonstrated that the monoterpenes have an active role in the decay resistance of longleaf pine stump heartwood, these compounds do persist for a very long time and thus are available should they serve this function.
A Single-Computer Grid Gateway Using Virtual Machines (2005)

Grid middleware is enabling resource sharing between computing centres across the world and sites with existing clusters are eager to connect to the grid using middleware such as that developed by the LHC Computing Grid (LCG) project. However, the hardware requirements for access to the grid remain high: a standard LCG grid gateway requires four separate servers. We propose the use of virtual machine (VM) technology to run multiple OS instances, allowing a full grid gateway to be hosted on a single computer. This would significantly reduce the hardware, installation and management commitments required of a site that wants to connect to the grid. In this paper, we outline the architecture of a single-computer grid gateway. We evaluate implementations of this architecture using two popular open-source VMs: Xen and user-mode Linux (UML). Our results show that Xen outperforms UML for installation tasks and standard gateway operations. Configuration is similar to that of sites running multi-computer gateways, making it easy to keep site installation profiles synchronised. Our VM gateway architecture provides a low-cost entry path to the grid and will be of interest to many institutions wishing to connect their existing facilities.
Localizing expression of ambiguity (1988)

In this paper we describe an implemented program for localizing the expression of many types of syntactic ambiguity, in the logical forms of sentences, in a manner convenient for subsequent inferential processing. Among the types of ambiguities handled are prepositional phrases, very compound nominals, adverbials, relative clauses, and preposed prepositional phrases. The algorithm we use is presented, and several possible shortcomings and extensions of our method are discussed.
Separation of proteins from olive oil by CE: An approximation to the differentiation of monovarietal olive oils (2010)

The separation of proteins from olive oils by CE has been achieved for the first time in this work. Based on the protein profiles obtained using UV detection, a novel approach has also been proposed enabling the differentiation of monovarietal olive oils. An extraction procedure based on the precipitation of proteins in cold acetone and their isolation and solubilization in a hydro-organic medium prior to their in-capillary preconcentration in CE was a critical step in method development since proteins are minor components of olive oils. Then, a CE separation using a basic medium in a dynamically coated capillary originated electrophoretic profiles with multiple peaks from which seven of them were identified as proteins. When different monovarietal olive oils were injected, three different regions (zones I, II, and III) were identified. Zone III, called as differential zone, enabled to distinguish easily between extra virgin olive oils made from the Arbequina variety and the Picual and Hojiblanca varieties. This is the first time that protein profiles have been employed for the differentiation of botanical varieties of olive oils showing an enormous potential as traceability markers for these highly appreciated oils.

Mastitis in rural Gambian mothers and the protection of the breast by milk antimicrobial factors (1985)

Mastitis was found to be a sizeable clinical problem in a group of lactating Gambian mothers. The mean monthly incidence was 2.6% and repeated episodes of mastitis were common. The role of milk antimicrobial factors in the local defence of the breast against mastitis was investigated by analysis of IgA, IgG, IgM, C3, C4, lactoferrin and lysozyme in the breast milk of 10 mastitis patients. Acute inflammation of the breast was accompanied by the rapid appearance of high concentrations of serum-derived immunoproteins in mastitic milk. Changes in the milk levels of lactose, sodium and transferrin indicated that this was due to a temporary opening of the paracellular pathway. Concentrations of secretory immunoproteins (IgA, lactoferrin and lysozyme) exhibited a delayed response, being elevated one week after the attack of mastitis. The normal milk of mastitis sufferers was significantly deficient in IgA, C3 and lactoferrin when compared with other lactating women suggesting that the former were predisposed to mastitis.
A Least Mean-Square Filter for the Estimation of the Cardiopulmonary Resuscitation Artifact Based on the Frequency of the Compressions (2009)

Cardiopulmonary resuscitation (CPR) artifacts caused by chest compressions and ventilations interfere with the rhythm diagnosis of automated external defibrillators (AED). CPR must be interrupted for a reliable diagnosis. However, pauses in chest compressions compromise the defibrillation success rate and reduce perfusion of vital organs. The removal of the CPR artifacts would enable compressions to continue during AED rhythm analysis, thereby increasing the likelihood of resuscitation success. We have estimated the CPR artifact using only the frequency of the compressions as additional information to model it. Our model of the artifact is adaptively estimated using a least mean-square (LMS) filter. It was tested on 89 shockable and 292 nonshockable ECG samples from real out-of-hospital sudden cardiac arrest episodes. We evaluated the results using the shock advice algorithm of a commercial AED. The sensitivity and specificity were above 95% and 85%, respectively, for a wide range of working conditions of the LMS filter. Our results show that the CPR artifact can be accurately modeled using only the frequency of the compressions. These can be easily registered after small changes in the hardware of the CPR compression pads.
The effects of sildenafil on ocular blood flow (2005)

Sildenafil causes a significant increase in blood flow in these arteries. A possible role of inhibition of phosphodiesterase-5 in vascular smooth muscles by sildenafil is implicated. Further studies are needed to investigate the effects of sildenafil on ocular blood flow in patients with senile macular degeneration, diabetic retinopathy and glaucoma.
Comparison of Transesophageal Echocardiographic and Scintigraphic Estimates of Left Ventricular End-Diastolic Volume Index and Ejection Fraction in Patients Following Coronary Artery Bypass Grafting (1990)

Transesophageal echocardiography (TEE) has become a commonly used monitor of left ventricular (LV) function and filling during cardiac surgery. Its use is based on the assumption that changes in LV short-axis ID reflect changes in LV volume. To study the ability of TEE to estimate LV volume and ejection immediately following CABG, 10 patients were studied using blood pool scintigraphy, TEE, and thermodilution cardiac output (CO). A single TEE short-axis cross-sectional image of the LV at the midpapillary muscle level was used for area analysis. Between 1 and 5 h postoperatively, simultaneous data sets (scintigraphy, TEE, and CO) were obtained three to five times in each patient. End-diastolic (EDa) and end-systolic (ESa) areas were measured by light pen. Ejection fraction area (EFa) was calculated (EFa = (EDa - ESa)/EDa). When EFa was compared with EF by scintigraphy, correlation was good (r = 0.82 SEE = 0.07). EDa was taken as an indicator of LV volume and compared with LVEDVI which was derived from EF by scintigraphy and CO. Correlation between EDa and LVEDVI was fair (r = 0.74 SEE = 3.75). The authors conclude that immediately following CABG, a single cross-sectional TEE image provides a reasonable estimate of EF but not LVEDVI.
Exposure: A White-Box Photo Post-Processing Framework (2017)

Retouching can significantly elevate the visual appeal of photos, but many casual photographers lack the expertise to do this well. To address this problem, previous works have proposed automatic retouching systems based on supervised learning from paired training images acquired before and after manual editing. As it is difficult for users to acquire paired images that reflect their retouching preferences, we present in this paper a deep learning approach that is instead trained on unpaired data, namely a set of photographs that exhibits a retouching style the user likes, which is much easier to collect. Our system is formulated using deep convolutional neural networks that learn to apply different retouching operations on an input image. Network training with respect to various types of edits is enabled by modeling these retouching operations in a unified manner as resolution-independent differentiable filters. To apply the filters in a proper sequence and with suitable parameters, we employ a deep reinforcement learning approach that learns to make decisions on what action to take next, given the current state of the image. In contrast to many deep learning systems, ours provides users with an understandable solution in the form of conventional retouching edits, rather than just a "black-box" result. Through quantitative comparisons and user studies, we show that this technique generates retouching results consistent with the provided photo set.

Photocatalytic oxidation of ethane over TiO<sub>2</sub> (1985)

Abstract The photocatalytic oxidation of ethane has been studied at room temperature using a specially designed stirred reactor. The effect on the rate of ethane oxidation, of the partial pressure of reactants, the UV light intensity, the amount of catalyst and the residence time has been evaluated. Running the experiments according to a factorial plan permitted to deduce from a limited amount of experimental data the complete kinetic model corresponding to the steady state adsorption mechanism. On the basis of the experimental critical mass of the catalyst (1.5 g), an expression permitting calculation of the critical mass of the catalyst (TiO 2 ) for any type of photocatalytic reactor has been derived.

Cell Release of Bioactive Fibroblast Growth Factor 2 by Exon 6-encoded Sequence of Vascular Endothelial Growth Factor (1997)

Vascular endothelial growth factor (VEGF) is a potent angiogenic factor which is synthesized and secreted by many differentiated cells in response to various stimuli including hypoxia and growth factor exposure. Alternative splicing of vascular endothelial growth factor mRNA results in three distinct molecular forms: V189 and V165 or V121 which lack the exons 6 or 6 and 7, respectively. To clarify the functions of the 24-amino acid insertion, the biological activity of V165 was compared with that exerted by purified recombinant V189 and a synthetic peptide designed on the sequence encoded by exon 6 (Ex6P). V189 and Ex6P, but not V165, induced cell proliferation on corneal endothelial cells cultured in vitro. These effects were due to the release of fibroblast growth factor 2 (FGF2) stored in the extracellular matrix but not to direct interactions with FGF receptors since V189 was inefficient on heparan sulfate-deficient cells expressing constitutively FGF-R1. Moreover corneas incubated ex vivo with Ex6P solubilized 10-fold more FGF2 than a isocationic peptide containing a scrambled sequence. Ex6P elicited an angiogenic response in a corneal pocket assay which was totally inhibited by addition of anti-FGF2 IgG. Moreover the angiogenic response to V189, but not to V165, was inhibited by FGF2 immunoneutralization. These findings demonstrate that the presence of the exon 6-encoded sequence confers VEGF with the ability to exert its biological effects through FGF2 signaling pathways.
Calibration curve for infrared spectrophotometry of nitrogen in silicon (1985)

A calibration curve for infrared absorptiometry of nitrogen in silicon at 963 cm−1 was obtained by the use of charged particle activation analysis with the 14N(p, α) 11C reaction. For as-grown floating zone (FZ) silicon, it is expressed as [nitrogen concentration at. cm−3)] =(1.83±0.24)×1017 (absorption coefficient). For heat-treated FZ silicon and Czochralski (CZ) silicon, this relation was found to give underestimated nitrogen concentration suggesting the existence of infrared insensitive nitrogen.
Influence of Fluid Physical Properties on Ink-Jet Printability (2009)

Ink-jet printing is a method for directly patterning and fabricating patterns without the need for masks. To achieve this, the fluids used as inks must have the capability of being stably and accurately printed by ink-jetting. We have investigated the inter-relationship between ink-jet printability and physical fluid properties by monitoring droplet formation dynamics. The printability of the fluids was determined using the inverse (Z) of the Ohnesorge number (Oh) which relates to the viscosity, surface tension, and density of the fluid. We have experimentally defined the printable range as 4 < or = Z < or = 14 by considering characteristics such as single droplet formability, positional accuracy, and maximum allowable jetting frequency.
