Migration of seismic data by phase shift plus interpolation (1984)

Abstract Generalization of the concepts of the phase-shift method to media having lateral velocity variations. Wave extrapolation in two steps. In the first step, the wave field is extrapolated by the phase-shift method; in the second step, the actual wave field is computed by interpolation from the reference wave fields. The phase shift plus interpolation (PSPI) method is unconditionally stable and lends itself conveniently to migration of three-dimensional data. Performance is demonstrated on synthetic examples. PSPI migration results are then compared with those obtained from a finite-difference method.--Modified journal abstract.

The Effect of Nitrous Oxide on Chest Wall Function in Humans and Dogs (1998)

In this study, we examined the effects of nitrous oxide on breathing in halothane-anesthetized dogs and humans. Nitrous oxide affected breathing by changing the distribution and timing of neural drive to the respiratory muscles in a species-dependent manner, rather than by causing a global depression of their activity.

Airline Choices for the Future (2016)

Airline Choices for the Future: From Alliances to Mergers offers an up-to-date assessment of the industry as it stands today, delivering a comprehensive insight into how the world of airline alliances is changing, and how the merger phenomenon is likely to fit into the new scenario. The purpose of this book is twofold. Firstly, it outlines the evolution and the reasons behind alliances between international air carriers, the alliances' track records and the way they have affected airlines and the air transport industry. Secondly, drawing on past and more recent developments in the industry, it examines the experiences airlines involved in cross-border mergers have gone through and the advantages and difficulties they have come across. Alliances and mergers are presented from both the airline and the consumer perspective. The book provides a balanced account of where mergers and alliances have taken the industry to date, bridging the gap between merger theory and implemented practices and strategies. It also identifies the challenges alliances and cross-border mergers have faced and highlights the key forces affecting airline development. Theoretical evidence is supplemented by data collected via surveys and interviews with airline executives, aviation experts, consultants and regulatory bodies.
Estimation of a signal waveform from noisy data using low-rank approximation to a data matrix (1993)

An analysis and improvement of a data-adaptive signal estimation algorithm are presented. Perturbation analysis of a reduced-rank data matrix is used to reveal its statistical properties. The obtained information is used for calculating the performance of the Toeplitz-restoration algorithm of D. Tufts et al. (1982). This analysis leads to improvements of the methods, and the predicted improvements are demonstrated by simulation and comparison with the Cramer-Rao bounds.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Pulmonary nodule segmentation in thoracic 3D CT images integrating boundary and region information (2003)

Accurately segmenting and quantifying pulmonary nodules structure is a key issue in three-dimensional (3-D) computer-aided diagnosis (CAD) schemes. This paper presents a segmentation approach of pulmonary nodules in thoracic 3-D images. This approach consists of two processes such as a pre-process for removing vessels attached and a surface deformation process. The pre-process is performed by 3-D gray-scale morphological operations. The surface deformation model used here integrates boundary and region information to deal with inappropriate position or size of an initial surface. This approach is derived through a 3-D extension of the geodesic active region model developed by Paragios and Deriche. First, in order to measure differences between the nodule and other regions a statistical analysis of the observed intensity is performed. Based on this analysis, the boundary and region information are represented by boundary and region likelihood, respectively. Second, an objective function is defined by integrating boundary and region-based segmentation modules. This integration aims at seeking surfaces that provide high boundary likelihood and high posterior segmentation probability. Finally, the deformable surface model is obtained by minimizing the objective function and, is implemented by a level set approach. We demonstrate an advantage of the proposed segmentation approach in comparison with the conventional deformable surface model using a practical 3-D pulmonary image.
Delayed Normalization of Central D2 Dopamine Receptor Availability After Discontinuation of Haloperidol Decanoate (1997)

Our preliminary finding of persistence of D2 dopamine receptor occupancy indicates that commonly used doses of haloperidol decanoate (200 mg every 4 weeks) maintain antipsychotic levels of receptor occupancy even 16 weeks after discontinuation of treatment. This may explain the lower relapse rates in patients withdrawn from depot neuroleptic treatment compared with those withdrawn from oral treatment. In addition, the remaining occupancy may confound the clinical evaluation of subsequent treatments. For controlled clinical trials of new antipsychotic drugs, we suggest a minimum washout of 6 months after the last depot injection.

Nanostructured materials for photocatalysis (2019)

Photocatalysis is a green technology which converts abundantly available photonic energy into useful chemical energy. With a rapid rise of flow photoreactors in the last decade, the design and development of novel semiconductor photocatalysts is happening at a blistering rate. Currently, developed synthetic approaches have allowed the design of diverse modified/unmodified semiconductor materials exhibiting enhanced performances in heterogeneous photocatalysis. In this review, we have classified the so far reported highly efficient modified/unmodified semiconductor photocatalysts into four different categories based on the elemental composition, band gap engineering and charge carrier migration mechanism in composite photocatalysts. The recent synthetic developments are reported for each novel semiconductor photocatalyst within the four different categories, namely: pure semiconductors, solid solutions, type-II heterojunction nanocomposites and Z-scheme. The motivation behind the synthetic upgrading of modified/unmodified (pure) semiconductor photocatalysts along with their particular photochemical applications and photoreactor systems have been thoroughly reviewed.
Turning PMMA Nanofibers into Graphene Nanoribbons by In Situ Electron Beam Irradiation (2008)

Graphene nanoribbons are formed from ultrathin electrospun poly(methyl methacrylate) (PMMA) nanofibers by electron beam irradiation. The number and width of the graphene sheets can be controlled precisely (see figure), providing a novel method of obtaining designed graphenes. This graphitization technique could be combined with electron beam lithography in the future to obtain high-resolution patterned graphite circuits.
Local convergence of large random triangulations coupled with an Ising model (2020)

We prove the existence of the local weak limit of the measure obtained by sampling random triangulations of size <inline-formula content-type="math/mathml"> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="n"> <mml:semantics> <mml:mi>n</mml:mi> <mml:annotation encoding="application/x-tex">n</mml:annotation> </mml:semantics> </mml:math> </inline-formula> decorated by an Ising configuration with a weight proportional to the energy of this configuration. To do so, we establish the algebraicity and the asymptotic behaviour of the partition functions of triangulations with spins for any boundary condition. In particular, we show that these partition functions all have the same phase transition at the same critical temperature. Some properties of the limiting object – called the Infinite Ising Planar Triangulation – are derived, including the recurrence of the simple random walk at the critical temperature.
Scalability and Its Application to Multicube (1989)

In parallel processing, scalability is an important issue for both applications and systems, with scaling arguments being presented for most large-scale multiprocessors. Even with such widespread interest, the notion of what constitutes a scalable multiprocessor ambiguous.&#13;\n\tIn this paper we first present a realistic, quantitative definition of scalability based on a multiprocessor?s ability to execute a problem in roughly constant time, given that the number of processors scale in proportion to the complexity of the problem. We then use the definition to demonstrate that the Multicube architecture is scalable by showing that (1) sufficient bus bandwidth is provided to support scalable applications, and 2) broadcast invalidations and non-uniform memory accesses are handled efficiently. We discuss, for example, how the propagation of broadcast invalidations may be limited by the use of special pruning caches, and how Multicube?s cache coherency hardware and synchronization primitives can be used to limit the degradation from non-uniform memory access patterns.
Fracture toughness evaluation of silicon nitride from microstructures via convolutional neural network (2022)

Abstract The fracture toughness of silicon nitride (Si 3 N 4 ) ceramics was evaluated directly from their microstructures via deep learning using convolutional neural network models. Totally 156 data sets containing microstructural images and relative densities were prepared from 45 types of Si 3 N 4 samples as input feature quantities (IFQs) and were correlated to the fracture toughness as an objective variable. The data sets were divided into two groups. One was used for training, resulting in the creation of regression models for two kinds of IFQs: the microstructures only and a combination of the microstructures and the relative densities. The other group was used for testing the validity of the created models. As a result, the determination coefficient was approximately 0.8 even when using only the microstructures as the IFQs and was further improved when adding the relative densities. It was revealed that the fracture toughness of Si 3 N 4 ceramics was well evaluated from their microstructures.
A novel electronically-controlled linear escapement mechanism (2014)

The linear escapement mechanism presented in this paper has been developed to assist in a task where a large thrust force (>10 N) is required with a high positioning resolution (<;0.5 mm) in a battery-powered device. This paper describes the behaviour of the escapement, the design process, based on the dynamic modelling of the output, and the sizing of the key features with a view towards miniaturisation. A prototype is used to validate the design options.
Bile Acid Derivatives as Ligands of the Farnesoid X Receptor: Molecular Determinants for Bile Acid Binding and Receptor Modulation (2014)

Bile acids are a peculiar class of steroidal compounds that never cease to amaze. From being simple detergents with a primary role in aiding the absorption of fats and fat-soluble vitamins, bile acids are now widely considered as crucial hormones endowed with genomic and non-genomic functions that are mediated by their interaction with several proteins including the nuclear receptor Farnesoid X Receptor (FXR). Taking advantages of the peculiar properties of bile acids in interacting with the FXR receptor, several biliary derivatives have been synthesized and tested as FXR ligands. The availability of these compounds has contributed to characterize the receptor from a structural, patho-physiological and therapeutic standpoint. Among these, obeticholic acid is a first-in-class FXR agonist that is demonstrating hepatoprotective effects upon FXR activation in patients with liver diseases such as primary biliary cirrhosis and nonalcoholic steatohepatitis. This review provides an historical overview of the rationale behind the discovery of obeticholic acid and chemical tools generated to depict the molecular features and bio-pharmacological relevance of the FXR receptor, as well as to summarize structure-activity relationships of bile acid-based FXR ligands so far reported.
Physiological and molecular characterisation of cadmium stress in Schmidtea mediterranea (2012)

The planarian Schmidtea mediterranea is a well-studied model organism for developmental research, because of its stem cell system. This characteristic also provides a unique opportunity to study stress management and the effect of stress on stem cells. In this study, we characterised the stress signature at different levels of biological organization. The carcinogenic metal cadmium was used as a model chemical stressor. We focused on stem cell activity and its interaction with other known stress parameters. Here, we have found that S. mediterranea is able to cope with high internal levels of cadmium. At endpoints such as size and mobility, cadmium-related stress effects were detected but all of these responses were transient. Correspondingly, cadmium exposure led to an elevated mitotic activity of the neoblasts, at the same time points when the other responses disappeared. At the molecular level, we observed redox-related responses that can be linked with both repair as well as proliferation mechanisms. Together, our results suggest that these animals have a high plasticity. The induction of stem cell activity may underlie this 'restoring' effect, although a carcinogenic outcome after longer exposure times cannot be excluded.
Biological True and False Serological Tests for Syphilis: Their Relationship with Anticardiolipin Antibodies (1990)

Anticardiolipin antibodies (ACA) were determined by an ELISA assay in 142 VDRL-positive patients who were classified in two groups: group I consisted of 77 patients with syphilis and group II of 65 patients with biological false-positive reaction in the standard test for syphilis. In group I 10% had ACA versus 52% in group II (p less than 0.0001). Isotype distribution in group II showed a predominance of IgG. These results suggest that antiphospholipid antibodies in VDRL and ACA tests have different specificities.
Improve Integration of In Vitro Biofilm Body of Knowledge to Support Clinical Breakthroughs in Surgical Site Infection (2021)

Prosthetics increase the risk of deep surgical site infections in procedures intended to restore function. In orthopaedics, prosthetic joint infections can lead to repetitive surgeries, amputation, or worse. Biofilm formation both in vitro and in vivo involves stages of attachment, accumulation, and maturation. The level of maturation affects susceptibility to antibiotics, the immune system, and the success of surgical interventions. A review of the literature indicates that orthopedic publications are less likely to mention biofilm. We have reviewed animal models of infection to assess in vivo models of prosthetic infection. Although most prosthetic infections seem to originate from local skin microbiota, clinically representative biofilm inocula are unusual. Biofilm-related end points are more widely adopted, but studies rarely include both quantification of adherent microbial burden and imaging of the in vivo biofilm. Failure to differentiate between planktonic and biofilm infections can skew research away from needed chronic disease models. In this review, we address prosthetic joint infections as an important model for chronic biofilm infection research, identify critical requirements for in vivo models of chronic infection, and propose that resistance to the terminology of biofilm research exists within both research and regulation, which could limit progress toward important orthopaedic targets.
Possible intermediates of Cu(phen)-catalyzed C–O cross-coupling of phenol with an aryl bromide by in situ ESI-MS and EPR studies (2014)

The C-O coupling reaction between 2,4-dimethylphenol and 4-bromotoluene catalyzed by the CuI/K2CO3/phen system can be inhibited by the radical scavenger cumene. Complexes [Cu(i)(phen)(1-(2,4-dimethylphenoxy)-4-methylbenzene)](+) (denoted as A), {H[Cu(i)(phen)(2,4-dimethylphenoxy)]}(+) and [Cu(i)(2,4-dimethylphenoxy)2](-) (denoted as B) were observed by in situ electrospray ionization mass spectrometry (ESI-MS) analysis of the copper(i)-catalyzed C-O coupling reaction under the catalytic reaction conditions indicating that they could be intermediates in the reaction. The in situ EPR study of the reaction solution detected the Cu(ii) species with a fitted g value of 2.188. A catalytic cycle with a single electron transfer (SET) step was proposed based on these observations.

Concise Synthesis of Substituted Quinolizin‐4‐ones by Ring‐Closing Metathesis (2014)

Abstract The 4 H ‐quinolizin‐4‐one scaffold is of significant pharmaceutical interest. This heterocyclic structure is predicted to have attractive physico‐chemical properties and is present in a variety of biologically active molecules. Despite these interesting characteristics, 4 H ‐quinolizin‐4‐ones are largely under‐represented in current small molecule screening libraries, and, therefore, this scaffold has been poorly investigated. Herein, a new strategy is reported for the syntheses of these rare and biologically interesting 4 H ‐quinolizin‐4‐ones. This modular route involves the regioselective N ‐alkylation of 6‐halo‐2‐pyridones followed by a Stille cross‐coupling, ring‐closing metathesis, and palladium‐catalyzed dehydrogenation reaction sequence. This method furnishes the target compounds in good yields and allows for access to unusual substitution patterns that are difficult to achieve by using other synthetic strategies.
Hierarchical Stochastic Block Model for Community Detection in Multiplex Networks (2019)

Multiplex networks have become increasingly more prevalent in many fields, and have emerged as a powerful tool for modeling the complexity of real networks. There is a critical need for developing inference models for multiplex networks that can take into account potential dependencies across different layers, particularly when the aim is community detection. We add to a limited literature by proposing a novel and efficient Bayesian model for community detection in multiplex networks. A key feature of our approach is the ability to model varying communities at different network layers. In contrast, many existing models assume the same communities for all layers. Moreover, our model automatically picks up the necessary number of communities at each layer (as validated by real data examples). This is appealing, since deciding the number of communities is a challenging aspect of community detection, and especially so in the multiplex setting, if one allows the communities to change across layers. Borrowing ideas from hierarchical Bayesian modeling, we use a hierarchical Dirichlet prior to model community labels across layers, allowing dependency in their structure. Given the community labels, a stochastic block model (SBM) is assumed for each layer. We develop an efficient slice sampler for sampling the posterior distribution of the community labels as well as the link probabilities between communities. In doing so, we address some unique challenges posed by coupling the complex likelihood of SBM with the hierarchical nature of the prior on the labels. An extensive empirical validation is performed on simulated and real data, demonstrating the superior performance of the model over single-layer alternatives, as well as the ability to uncover interesting structures in real networks.
