Robust polynomial fitting method for regional gravity estimation (1991)

Abstract Standard polynomial fitting methods are inconsistent in their formulation. The regional field is approximated by a polynomial fitted to the observed field. As a result, in addition to the nonuniqueness in the definition of the regional field, the fitted polynomial is strongly influenced by the residual field (observed field minus regional field). We present a regional-residual separation method for gravity data which uses a robust procedure to determine the coefficients of a polynomial fitted to the observations. Under the hypothesis that the regional can be modeled correctly by the polynomial surface, the proposed method minimizes the influence of the residual field in the fitted surface.The proposed method was applied to real gravity data from Ceara state, Brazil, and produced information on zones of possible crustal thickening and the occurrence of lower-crustal granulitic rocks thrust into the shallow subsurface.
Flat optics with cholesteric and blue phase liquid crystals (2016)

The cholesteric (Ch) phase is an ancient liquid crystal (LC) phase, with its roots dating back to the days of Friedrich Reinitzer. It is most well known for its ability to selectively reflect circularly polarised light with the same rotation handedness as the helical structure, and have found applications in polarising and display devices. Most studies to date utilising the reflective properties of ChLCs, however, have treated ChLCs as simple dielectric mirrors in which light follows the law of reflection. We have recently shown that through controlling the phase of the Ch helix, it is possible to control the phase of reflected light. Because the phase can be controlled over 0–2π, the reflected wavefront from a planar device can be designed to possess non-specular properties, such as deflection and lensing. In this paper, we aim to provide a comprehensive understanding of the phenomenon by presenting theoretical and experimental results on the dependence of the reflected light phase on the helix phase, and the effect of chiral handedness on the phenomenon. Also, we show that wavefront manipulation based on the same concept can be achieved in Ch blue phases (BPs), which are chiral LCs with three-dimensional periodicity.
Semi-supervised Learning by Maximizing Smoothness (2004)

We consider the general problem of learning from labeled and unlabeled data. Given a set of points, some of them are labeled, and the remaining points are unlabeled. The goal is to predict the labels of the unlabeled points. Any supervised learning algorithm can be applied to this problem, for instances, Support Vector Machines (SVMs). The problem of our interest is if we can implement a classier which uses the unlabeled data information in some way and has higher accuracy than the classiers which use the labeled data only. Here we propose a simple algorithm to utilize the unlabeled data. The basic idea is to construct the classifying function which sucien tly smooth with respect to the intrinsic global structure collectively revealed by known labeled and unlabeled points. The method yields encouraging experimental results on a number of classication problems and demonstrates eectiv e use of unlabeled data.
Image fusion algorithm based on redundant-lifting NSWMDA and adaptive PCNN (2014)

Aiming at the applications of image fusion with high contrast and texture information, an effective image fusion method based on redundant-lifting non-separable wavelet multi-directional analysis (NSWMDA) and adaptive pulse coupled neural network (PCNN) has been proposed. The original images are firstly decomposed by using the NSWMDA into several subbands to retain texture detail and contrast information, then adaptive PCNN algorithm is applied on the high frequency directional subbands to extract the high frequency information, the low frequency subbands are evaluate by weighted average method based on Gaussian kernel. Experimental results show that the proposed method can make the fused image maintains more texture details and contrast information.
3D printing technique applied to rapid casting (2007)

Purpose The purpose of this paper is to verify the feasibility and evaluate the dimensional accuracy of two rapid casting (RC) solutions based on 3D printing technology: investment casting starting from 3D‐printed starch patterns and the ZCast process for the production of cavities for light‐alloys castings. Design/methodology/approach Starting from the identification and design of a benchmark, technological prototypes were produced with the two RC processes. Measurements on a coordinate measuring machine allowed calculating the dimensional tolerances of the proposed technological chains. The predictive performances of computer aided engineering (CAE) software were verified when applied to the ZCast process modelling. Findings The research proved that both the investigated RC solutions are effective in obtaining cast technological prototypes in short times and with low costs, with dimensional tolerances that are completely consistent with metal casting processes. Practical implications The research assessed the feasibility and dimensional performances of two RC solutions, providing data that are extremely useful for the industrial application of the considered technologies. Originality/value The paper deals with experimental work on innovative techniques on which data are still lacking in literature. In particular, an original contribution to the determination of dimensional tolerances and the investigation on the predictive performances of commercial CAE software is provided.
Detecting Malicious Logic Through Structural Checking (2007)

Hardware is just as susceptible as software to "hacker attacks", through inclusion of malicious logic; and the consequences of such an attack could be disastrous! The impact of software viruses has been felt, at one time or another, by the entire computerized world, through loss of productivity, loss of system resources or data, or mere inconvenience. However, the nature of malicious logic and defending against it is fundamentally different from its software counterpart. Malicious logic has the added dimension of not being removable once encapsulated in the system. This paper will identify hardware vulnerabilities and will outline an automated method, called structural checking, to detect and prevent malicious logic from becoming incorporated into an ASIC, which could cause catastrophic system failure, security breaches, or other dire consequences.

Extracting Certainty from Uncertainty: Regret Bounded by Variation in Costs. (2008)

Prediction from expert advice is a fundamental problem in machine learning. A major pillar of the field is the existence of learning algorithms whose average loss approaches that of the best expert in hindsight (in other words, whose average regret approaches zero). Traditionally the regret of online algorithms was bounded in terms of the number of prediction rounds. Cesa-Bianchi, Mansour and Stoltz [4] posed the question whether it is be possible to bound the regret of an online algorithm by the variation of the observed costs. In this paper we resolve this question, and prove such bounds in the fully adversarial setting, in two important online learning scenarios: prediction from expert advice, and online linear optimization. 1
A Design for a List Merging Network (1979)

In inverted file database systems (and in a number of other applications), much of the processing consists of merging two or more previously sorted lists based on a Boolean expression. Conventional general purpose computers are not well suited for this type of operation, with even well written programs utilizing less than 10 percent of the available memory capacity for actual processing of data. However, a low-cost special purpose backend processor can be used to efficiently handle the list merging operations, freeing the conventional processor for other uses.
Two‐stage solvent extraction of seeds of <i>Hibiscus abelmoschus</i> linn: Lipid and FA compositions (2003)

Abstract The lipid and FA compositions of TAG seed oil of ambrette ( Hibiscus abelmoschus ), contrary to earlier reports, were found to contain only a small amount of epoxy FA. Higher HBr absorption values were shown to be due to the presence of fragrance components of the seed coat in the oil derived from intact whole seeds. Cyclopropene/cyclopropane acids in the FAME were determined to be about 1.5% by GLC, while epoxy acids were less than 1% by two different methods. Based on the physicochemical characteristics and lipid and FA compositions of the fresh and methanol‐extracted seeds, ambrette TAG oil may be a candidate for edible use. The process of selective recovery of the expensive fragrant oily concentrate in higher yield in a first step and of an edible fatty oil in a second step makes it an attractive economic proposal.
Novel Therapies for Pseudomonas aeruginosa Pneumonia (2011)

P. aeruginosa is the bacteria most commonly responsible for hospital-acquired and ventilator-associated pneumonia. Numerous factors are encoded in its genome, and they explain its high virulence. P. aeruginosa also develops a quorum sensing (QS), which coordinates the expression of these factors. The type III secretion system, a needle-complex, allows exotoxin injections into eukaryotic cells and is involved in the pathogenesis of acute pneumonia. This pathogen develops a high level of resistance to all antibiotics, which leads to a shortage of treatment options for many patients. Thus, new preventive or therapeutic approaches are in development. Immunotherapy that uses monoclonal antibodies has been successfully tested in blocking the type III secretion system (anti-PcrV) or helping immune cells phagocytose P. aeruginosa. Inhibiting the quorum sensing has also been efficacious in vitro and in vivo. New antibacterial peptides may enlarge the panel of treatments in the near future. However, current treatment for patients still relies on antibiotics. The development of resistance to all classes of available antibiotics leads to colistin revival with good clinical results. Topical delivery through aerosol could allow for the increase in the antibiotic concentration inside the infection site while limiting its systemic toxicity. Finally, Candida airway colonization has been found to be associated with P. aeruginosa-associated pneumonia in ventilated patients. In addition to targeting the bacteria, reducing Candida airway colonization may also decrease the incidence of such infections.
Zero temperature coefficient of resonant frequency in an X-cut lithium tantalate at room temperature (1969)

Two methods are presented which make it possible to obtain a zero temperature coefficient of the resonant frequency at room temperature in X-cut lithium tantalate resonators. The first method uses a series capacitance and the second method uses a trapped energy mode of vibration.
Antisense Oligonucleotide Mediated Splice Correction of a Deep Intronic Mutation in OPA1 (2016)

Inherited optic neuropathies (ION) present an important cause of blindness in the European working-age population. Recently we reported the discovery of four independent families with deep intronic mutations in the main inherited optic neuropathies gene OPA1. These deep intronic mutations cause mis-splicing of the OPA1 pre-messenger-RNA transcripts by creating cryptic acceptor splice sites. As a rescue strategy we sought to prevent mis-splicing of the mutant pre-messenger-RNA by applying 2'O-methyl-antisense oligonucleotides (AONs) with a full-length phosphorothioate backbone that target the cryptic acceptor splice sites and the predicted novel branch point created by the deep intronic mutations, respectively. Transfection of patient-derived primary fibroblasts with these AONs induced correct splicing of the mutant pre-messenger-RNA in a time and concentration dependent mode of action, as detected by pyrosequencing of informative heterozygous variants. The treatment showed strong rescue effects (~55%) using the cryptic acceptor splice sites targeting AON and moderate rescue (~16%) using the branch point targeting AON. The highest efficacy of Splice correction could be observed 4 days after treatment however, significant effects were still seen 14 days post-transfection. Western blot analysis revealed increased amounts of OPA1 protein with maximum amounts at ~3 days post-treatment. In summary, we provide the first mutation-specific in vitro rescue strategy for OPA1 deficiency using synthetic AONs.

Effect of dietary fat selection on plasma cholesterol synthesis in older, moderately hypercholesterolemic humans. (1994)

To study factors controlling plasma cholesterol levels, the effect of dietary fat type on cholesterol synthesis was examined in 15 hypercholesterolemic subjects (low-density lipoprotein [LDL] cholesterol > 130 mg.dL-1) consuming over a period of 32 days (1) a baseline diet (36% kcal as fat: 15% saturated, 15% monounsaturated, and 6% polyunsaturated fat; 180 mg cholesterol.1000 kcal-1) and diets meeting National Cholesterol Education Program step 2 criteria (30% kcal as fat, < or = 7% saturated fat, 80 to 85 mg cholesterol/Mcal), where two thirds of the fat was either (2) olive, (3) corn, or (4) canola oil. Plasma total, LDL, and high-density lipoprotein (HDL) cholesterol and triglyceride levels were determined at the end of each period. Cholesterol fractional synthesis rate (FSR) was also measured as the deuterium (D) incorporation into plasma total cholesterol relative to body D2O level (1.2 g D2O.kg-1 estimated body water) over 24 hours. Absolute synthesis rates (ASRs) were determined as the product of FSR and rapid turnover cholesterol pool size. Plasma total and LDL cholesterol levels declined significantly (P < .005) on all plant-oil diets compared with the baseline diet; however, triglyceride levels were not different. FSRs were higher (P < .05) for the corn oil (0.0665 +/- 0.0097 pool.d-1) compared with baseline (0.0412 +/- 0.0060 pool.d-1) and olive oil (0.0409 +/- 0.0052 pool.d-1) but not canola oil (0.0492 +/- 0.0072 pool.d-1) diets.(ABSTRACT TRUNCATED AT 250 WORDS)
The genetic transformation of bone biology (1999)

The skeleton, like every organ, has specific developmental and functional characteristics that define its identity in biologic and pathologic terms. Skeleton is composed of multiple elements of various shapes and origins spread throughout the body. Most of these skeletal elements are formed by two different tissues, cartilage and bone, and each of these two tissues has its own specific cell types: the chondrocyte in cartilage, and the osteoblast and osteoclast in bone. Finally, each of these cell types has its own differentiation pathway, physiological functions, and therefore pathological conditions. The complexity of this organ in terms of developmental biology, physiology, and pathology, along with the multitude of important conceptual advances in our understanding of skeletal biology, are such that it has become impossible to present in a short review an up-to-date summary of both cartilage and bone biology. Thus, this review will concentrate only on bone biology beyond embryonic patterning. The entire bone field is dominated by the impact of degenerative diseases, such as osteoporosis. This mere fact does influence the research in bone biology and will influence the topics presented in this review. It is no surprise that, like for most other organogenesis pro
Stability analysis and control synthesis for switched systems: a switched Lyapunov function approach (2002)

This paper addresses the problem of stability analysis and control synthesis of switched systems in the discrete-time domain. The approach followed in this paper looks at the existence of a switched quadratic Lyapunov function to check asymptotic stability of the switched system under consideration. Two different linear matrix inequality-based conditions allow to check the existence of such a Lyapunov function. The first one is classical while the second is new and uses a slack variable, which makes it useful for design problems. These two conditions are proved to be equivalent for stability analysis. Investigating the static output feedback control problem, we show that the second condition is, in this case, less conservative. The reduction of the conservatism is illustrated by a numerical evaluation.
Synthesis and Physiological Activity of Toluyl Esters from 5-Methyl-2-Phenyl-2-Hexenal Derivatives (1999)

Physiologically active compounds, 5-methyl-2-phenyl-2-hexenal (1) from Idaho potatoes and related compounds, 4-methyl-2-phenyl-2-pentenal (2), 2-methyl-4-phenylpentanal (3) and 2-methyl-2-pentenal (4) were synthesized and used as starting compounds for the synthesis of twenty-one compounds through condensation with o-, m- and p-toluoyl chlorides. The derivatives obtained were examined for capacity as whitening agents and growth-regulation. (4h) derived from (4) were found to be inhibited by tyrosinase by 71%. This inhibitory action considerably exceeded that of arbutin used in commercial cosmetics. Seventeen derivatives were found effective for weed control in a field (50g/a), and showed particularly strong inhibitory action forward growth of Monochoria vaginalis.
Introduction (2002)

This chapter sets the background of the discussions presented in the chapters contained in this book. It presents the rationale behind the writing of the book and the specific focus of each chapter. This book aims to give accountability a proper place in the debate over European democracy and democratic deficit, dominated by the concepts of legitimacy and sovereignty. It originated as a set of lectures given at the European University Institute in Florence for the Academy of Law in July 2000, and developed around three institutional studies of legislatures, courts, and audit systems. Focus is given to the role of the European Court of Justice in building a European legal system, but also on the principles of procedural due process.
Swarm intelligence for routing in communication networks (2002)

Swarm intelligence, as demonstrated by natural biological swarms, exhibits numerous powerful features that are desirable in many engineering systems, such as communication networks. In addition, new paradigms for designing autonomous and scalable systems may result from analytically understanding and extending the design principles and operations inherent in intelligent biological swarms. A key element of future design paradigms will be emergent intelligence - simple local interactions of autonomous swarm members, with simple primitives, giving rise to complex and intelligent global behavior. Communication network management is becoming increasingly difficult due to the increasing network size, rapidly changing topology, and complexity. A new class of algorithms, inspired by swarm intelligence, is currently being developed that can potentially solve numerous problems of such networks. These algorithms rely on the interaction of a multitude of simultaneously interacting agents. A survey of such algorithms and their performance is presented here.
A Comparison of Steamflood Strategies: Five-Spot Pattern vs. Inverted Nine-Spot Pattern (1987)

Summary This paper describes the use of a black-oil, thermal simulator to compare steamflood development using five-spot and inverted nine-spot patterns. The input data selected were representative of a homogeneous heavy-oil reservoir. This study considered three different development strategies: conventional pattern steamflooding, pattern steamflooding with infill drilling, and steamflooding with infill drilling and pattern realignment. Comparison of pattern steamfloods indicates that at close well spacing (1.25 acres/well [0.5 ha/well]), the inverted nine-spot recovers more oil than the five-spot. Steam breakthrough and oil production are accelerated for the nine-spot relative to the five-spot pattern. At larger well spacing, however, oil recovery from the five-spot pattern exceeds that from the nine-spot. Conversion of a five-spot pattern to an inverted nine-spot increases and accelerates oil recovery. Processing of multiple sands will improve the effectiveness of this infill drilling strategy. A development strategy using inverted nine-spot patterns on large well spacings (2.5 to 5.0 acres/well [1 to 2 ha/well]) that yields improved oil recovery compared with conventional five-spot steamflood development was identified. This strategy uses infill drilling and pattern realignment to improve steamflood performance.
Preparation of Diethyl Phosphite by Oxidation of White Phosphorus in Ethyl Alcohol (1970)

Oxidation of P4 by O2 in ethyl alcohol was carried out in order to prepare HPO (OEt) 2, obtaining 43% yield. The reaction products were compared with the products obtained by the ethanolysis of P4O6 and with the products obtained by oxidation of P4 in CCl4, and the reaction mechanism was discussed.Reaction rate was affected by temperature. The P4 was oxidized, without detectable intermediate, into P3 and reacted immediately with ethyl alcohol and turned into the products. Alcohol might act the role of suppressing further oxidation of phosphorous derivatives. As products, HPO (OH) 2, HPO (OH) (OEt), HPO (OEt) 2 and condensed phosphorous acid were detected, but no P (OEt) 3 could be detected.
