Antibiotic Resistance of Commensal Staphylococcus aureus and Coagulase-Negative Staphylococci in an International Cohort of Surgeons: A Prospective Point-Prevalence Study (2016)

Nasal colonization with antibiotic resistant bacteria represents both a risk factor for the colonized individual and their immediate contacts. Despite the fact that healthcare workers such as orthopedic surgeons are at a critical interface between the healthcare environment and an at-risk patient population, the prevalence of antibiotic resistant bacteria within the surgical profession remains unclear. This study offers a snapshot of the rate of nasal colonization of orthopedic surgeons with multi-resistant staphylococci including methicillin-resistant S. aureus (MRSA) and methicillin-resistant coagulase-negative staphylococci (MRCoNS). We performed a prospective, observational study obtained at a single time point in late 2013. The participants were active orthopedic, spine and head & neck surgeons from 75 countries. The prevalence of nasal carriage of the different bacteria and the corresponding 95% confidence interval were calculated. From a cohort of 1,166 surgeons, we found an average S. aureus nasal colonization rate of 28.0% (CI 25.4;30.6) and MRSA rate of 2.0% (CI 1.3;2.9), although significant regional variations were observed. The highest rates of MRSA colonization were found in Asia (6.1%), Africa (5.1%) and Central America (4.8%). There was no MRSA carriage detected within our population of 79 surgeons working in North America, and a low (0.6%) MRSA rate in 657 surgeons working in Europe. High rates of MRCoNS nasal carriage were also observed (21.4% overall), with a similar geographic distribution. Recent use of systemic antibiotics was associated with higher rates of carriage of resistant staphylococci. In conclusion, orthopedic surgeons are colonized by S. aureus and MRSA at broadly equivalent rates to the general population. Crucially, geographic differences were observed, which may be partially accounted for by varying antimicrobial stewardship practices between the regions. The elevated rates of resistance within the coagulase-negative staphylococci are of concern, due to the increasing awareness of their importance in hospital acquired and device-associated infection.
[Cytogenetic data on sarcomas of the bone and soft tissue]. (1988)

Cytogenetic data are now available in most bone and soft tissue sarcomas. The characteristic chromosomal rearrangements observed are of great importance for the diagnosis, the classification and the comprehension of these cancers at the molecular level.
The Visual Analog Scale in the Immediate Postoperative Period (1998)

The visual analog scale was developed for assessing chronic pain but is often used in studies of postoperative pain. This study finds that the visual analog scale correlates well with a verbal 11-point scale but that any individual determination has an imprecision of +/- 20 mm.
Techniques in Infectious Diseases (2013)

Antibody-dependent enhancement (ADE) is a generally accepted hypothesis to explain increased viremia and disease severity during secondary human DENV infections. In addition to an increased number of infected cells, its mechanism has been postulated as either an increased uptake or an elevated production of viruses per infected cell during ADE infection. The latter postulate, however, has not been rigorously tested. Using Fc gamma receptor (Fcϒ R)-positive and type I IFN-positive (THP-1 and U937) or negative (K562) human myeloid cells, and a combination of techniques including flow cytometry, plaque assay, and real time qPCR assay, we found ADE infection led to significant burst size increase in all three cell types. Furthermore, we found comparable levels of virus uptake between ADE and direct dengue infection in THP-1 cells. Collectively, our results demonstrate that burst size increase is a common feature of dengue ADE infection, and that increased viral uptake during ADE infection is insufficient to account for the burst size increase. Thus, further mechanistic study is needed to uncover the intrinsic mechanisms of ADE infection.

Practice Patterns in the Management of Recurrent Acute Pancreatitis (2018)

Introduction: While recurrent acute pancreatitis (RAP) is generally defined as 2 or more episodes of acute pancreatitis without evidence of chronic pancreatitis, there are conflicting opinions regarding the correct management with this presentation. While some providers recommend ERCP in this setting, others consider RAP to be a contraindication to ERCP. Within the subset of patients referred for ERCP, the specific procedural intervention may vary widely and may involve manometry, biliary sphincterotomy, pancreatic sphincterotomy, or both. The objective of this study was to assess the practice patterns and clinical features influencing the management of RAP in the US. Methods: An anonymous 35-question survey instrument was developed and refined through multiple iterations and IRB-approved. The survey was distributed via email to 408 gastroenterologists in the United States to assess the practice patterns in the management of RAP in multiple clinical scenarios. Results: The survey was completed by 65 participants representing 36 of the top academic/tertiary care centers across the country. Eighty-eight percent of participants identified as having been in practice for at least six years with 52.3% performing at least 250 ERCPs per year. Additionally, 73.8% of respondents identified as a pancreatologist or specialized in pancreatology and 70.8% had completed a fellowship in advanced endoscopy. Overall, 90.8% of participants indicated that they might offer or recommend ERCP in the management of RAP. Ninety-five percent (P<0.001) of participants might offer ERCP to a patient with a dilatated pancreatic duct and pancreas divisum. A multinomial logistic regression was performed to analyze the independent impact of duct dilatation, pancreas divisum, symptoms and gender on the decision to offer or recommend ERCP. Duct dilatation and the presence of symptoms were the most predictive variables (P<0.001). The presence of pancreas divisum significantly increased the likelihood of a recommendation for ERCP (P=0.012). Gender was not significant (P=0.3419). Conclusion: In patients with RAP presenting to tertiary care centers in the US, a preponderance of respondents would consider ERCP. Pancreatic ductal dilatation, symptoms, and pancreas divisum significantly increased the likelihood that participants might offer ERCP. A prospective randomized trial would be useful in determining which interventions would most benefit patients presenting with RAP.
Simultaneous OCT/SLO/ICG Imaging (2009)

Simultaneous visualization of an en face (coronal, C-scan) OCT image and of an ICG angiogram, displayed side by side and superimposed, permits more precise correlations between late fluorescence accumulation with structures deep to the retinal surface at the retina-choroid interface. The multiplanar scanning also permits immediate B-scan OCT cross-sectional views of regions of abnormal fluorescence. The paper demonstrates the synergy between the two types of studies, functional and anatomic, in providing a more complete view of the pathologic condition.

USING DETAILED INDEPENDENT 3D SUB-MODELS TO IMPROVE FACIAL FEATURE LOCALISATION AND POSE ESTIMATION (2013)

We show that the results from searching 2D images or a video sequence, with a 3D head model can be improved by using detailed sub-models. These parts are initialised with the full model result and are allowed to search independently of that model, and of each other, using the same algorithm. The final results for the sub-models can be reported exactly, or optionally fed back into the full model to be constrained by its parameter space. In the case of a video sequence this can then be used in the initialisation of the next frame. We tested various data sets, constrained and unconstrained, including a variety of lighting conditions, poses, and expressions. Our investigation showed that using the sub-models improved on the original full model result on all but one of the data sets.
Architectural study of reconfigurable photonic Networks-on-Chip for multi-core processors (2009)

Photonic Networks-on-Chip (NoCs) have become a promising route to interconnect processor cores on chip multiprocessors (CMP) in a power efficient way. Although several photonic NoC proposals exist, their use is limited to the communication of large data messages due to a relatively long set-up time for the photonic channels. In this work, we evaluate a reconfigurable photonic NoC in which the topology is adapted automatically to the evolving traffic situation. This way, long photonic channel set-up times can be tolerated which makes our approach more compatible in the context of shared-memory CMPs.
Automating software analysis and testing using a program transformation system (1989)

We describe an approach to software analysis and test generation that combines several technologies: object-oriented databases and parsers for capturing and representing software; pattern languages for writing program templates and querying and analyzing a database of software; and transformation rules for automatically generating test cases based on the analysis results, and for automatically creating program “mutants” to determine adequacy of coverage of the test cases. We present a program transformation system, REFINE™1, that incorporates these technologies in an open environment for software analysis and test generation. Next we present concrete examples of how our approach is being applied to analysis and test generation for C software.
Run-time monitoring of real-time systems (2002)

A model and an implementation of a run-time environment for specifying and monitoring properties of real-time systems are presented. The proposed approach supports annotating real-time programs with events that are recorded and examined at run-time. The authors provide two general methods for synchronous or asynchronous monitoring of real-time constraints. In the synchronous case, a system constraint is embedded inside a program; thus, the constraint is examined at a particular point in the execution of a real-time task. In the asynchronous case, a constraint is monitored by a separate task during the entire execution of real-time tasks. The authors also describe an implementation of a run-time monitoring toolkit as a set of library function calls in C.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Scintillating Imaging Proportional Counter as X-Ray to Light Image Converter (1977)

A xenon detector has been constructed which converts soft X-rays to UV photons while preserving the spatial position of the X-rays in two dimensions. More than 50 UV photons are collected in the image for each 5.9 keV X-ray. The spatial resolution of the present system is 0.5mm for integrated flux measurements and would probably be better for single photon counting. The detector can be made in a large area format without loss of resolution. In principle the system can image the very high X-ray fluxes which are required in certain applications with preservation of linearity in the image.
Relevance and Evaluation of Hydrogen and Disulfide Bond Contribution to the Mechanics of Hard α-Keratin Fibers (2019)

We propose a simple mechano-chemical model for the dependence of Young's modulus of α-keratin fibers on the hydrogen and disulfide bonds existing in the matrix and evaluate the relative change in bonding following an oxidative chemical treatment. Atomic force microscopy nanoindentation of longitudinal and cross sections of the fiber showed that, although the oxidative treatment breaks a significant amount of disulfide bonds, it introduces compensatory hydrogen bonds that maintain fiber elasticity at values comparable with those of the untreated fiber under dry conditions. The striking influence of humidity on the hydrogen bonding in keratin fibers is also evaluated. The hydrogen bonds are labeled as "type 1" and "type 2" hydrogen bonds; newly formed hydrogen bonds, type 2, are more labile than those native (type 1) to the matrix. Examining their contribution to Young's modulus of the matrix allowed for quantifying the loss of disulfide bonds, and the result matched the decrease in cystine, measured by amino-acid analysis, caused by the oxidative treatment.
Sorry, I only speak natural language: a pattern-based, data-driven and guided approach to mapping natural language queries to SPARQL. (2015)

We present a new interface based on natural language to support users in specifying their queries with respect to RDF datasets. The approach relies on a number of predefined patterns that uniquely determine a type of SPARQL query. The approach is incremental and assisted in that it guides a user step by step in specifying a query by incrementally parsing the input and providing suggestions for completion at every stage. The methodology to specify the patterns is informed by empirical distributions of SPARQL query types as found in standard query logs. So far, we have implemented the approach using two patterns only as proof-of-concept. The coverage of the pattern library will be extended in the future. We will also provide an evaluation of the approach on the well-known QALD dataset.
A Key Role of Orbital Interaction in the Main Group Element-containing π-Electron Systems (2004)

Abstract Various types of main group element-containing π-electron systems have been synthesized using silole, dibenzoborole, or bis-silicon-bridged stilbene as the key building units. In these π-electron systems, the orbital interaction between the main group element moiety and the π-conjugated framework, such as pπ–π* and σ*–π* conjugation, plays a crucial role in determining their characteristic electronic structures and makes them promising materials for applications in organic electronics and optoelectronics.
Window-based congestion control with heterogeneous users (2002)

We investigate the fundamental problem of achieving the system optimal rates, which maximize the total user utility, in a distributed network environment using only the information available at the end hosts. This is done by decomposing the overall system problem into subproblems for the network and for the individual users and introducing an incentive-compatible pricing scheme. The users are to solve the problem of maximizing individual net utility, which is their utility less the amount they pay. This is done using a window based algorithm. We provide an algorithm for the network to adjust its prices and the users to adjust their window sizes such that at an equilibrium the system optimum is achieved. It is notable that our algorithm does not require any explicit feedback from the network and can be deployed over the Internet with modifications only at the end hosts. Our scheme is incentive compatible in that there is no benefit to the users to lie about their utilities.

Small-Angle Neutron Scattering Studies of Mixed Cetyl Trimethylammonium Bromide−Butyl Benzene Sulfonate Solutions (2002)

The effect of hydrotropes, sodium salts of butyl benzene sulfonate (Na-BBS), viz., n-butyl benzene sulfonate (Na-nBBS), iso-butyl benzene sulfonate (Na-iBBS), and tert-butyl benzene sulfonate (Na-tBBS), on microstructures of cetyl trimethylammonium bromide (CTAB) in aqueous solutions has been studied using small-angle neutron scattering (SANS) and viscosity changes. The viscosity of CTAB solutions increased with the addition of the hydrotropes, but differently with different isomers. This behavior is attributed to the structural differences in the hydrotropes. The SANS studies indicated the growth of the CTAB micelles on the addition of the hydrotropes while the micellar shape changed from sphere to ellipsoid depending upon the structure of the hydrotrope. Na-nBBS showed the highest aggregation number and a lower fractional charge on the micelles as compared to the sterically hindered Na-tBBS, at the same concentration.
Intensification of the ultrafiltration process when separating aqueous solutions of acid dyes (2009)

We have investigated the impact of working pressure, the degree of sampling permeate, the pH of the medium on the transmembrane flow and retention capacity of a UPM-50 ultrafiltration membrane with respect to the dye acid yellow in the combination of the method of ultrafiltration and coagulation. It has been shown that the use of magnesium hydroxide for aggregation of anionic dyes makes it possible to substantially increase the efficiency of their membrane removal from the solution retaining high capacity of the ultrafiltration process.
An MPEG-21-enabled Video Adaptation Engine for Universal IPTV Access (2006)

In the context of Universal Multimedia Access (UMA), the user will be able to access and consume a rich set of multimedia content over dynamic and heterogeneous networks and devices. To rich this universal accessibility, the MPEG-21 multimedia framework is defining the entire multimedia content delivery chain (content creation, production, delivery, trade and consumption). The part 7 of this framework defines the digital item adaptation (DIA). The DIA specifies metadata for assisting the adaptation of digital item according to different constraint (storage, transmission, consumption). This paper presents an architecture and implementation of an MPEG-21-enabled Video Adaptation Engine (VAE) for allowing seamless IPTV access for heterogeneous devices and networks capabilities. The IPTV services considered in this paper are based on streaming Digital Video Broadcast –Terrestrial services over IP LAN and WLAN networks. The VAE is seen as a media gateway proxy with adaptation/streaming capabilities. The obtained results demonstrate the ability of our VAE to allow universal media access to digital content for a multitude of clients and network capabilities.
A policy driven approach to email services (2004)

The primary original design goal for email was to provide best-effort message delivery. Unfortunately, as the ever increasing uproar over SPAM demonstrates, the existing email infrastructure is no longer well suited to the worldwide set of email users - particularly email receivers. Rather than propose yet another band-aid solution to SPAM, this paper rethinks email from the requirements perspective, albeit with the constraint of designing a system suitable for incremental adoption in the current environment. Our result to this exercise is a policy driven email service in which the interests of each principal can be articulated and accommodated. Our scheme rewards faithful senders with better quality of service and discourages misbehavior. Our scheme provides receivers with policy-driven control over whether and how a given message appears in the recipients mailbox.
Thermoplastic Coated Carbon Fibers for Textile Preforms (1988)

A continuous process for producing prepreg from carbon fiber and thermo plastic matrix is described. After the tow has been spread using a pneumatic device, the process utilizes a fluidized bed to apply thermoplastic powder to the bundle. Finally, direct electrical heating of the coated fiber tow melts the polymer on the individual fibers, creating a uniform and extremely flexible prepreg. The efficiency of the process was evalu ated during initial trials in which a thermoplastic polyimide, LaRC-TPI, was applied to T-300, 3K (3000 filament) carbon fiber tow. The physical properties of unidirectional com posite specimens fabricated from this prepreg were measured, and the matrix uniformity and void content of the samples was determined. The results of these evaluations are detailed and discussed.
SU‐E‐T‐71: A Radiochromic Film Based Quantitative Assessment of Thermoplastic Mask Bolus Effect in Head and Neck IMRT/VMAT (2015)

Purpose: To quantify the factors leading to thermoplastic mask bolus‐associated‐increased skin dose in head and neck IMRT/VMAT using EBT2 film. Methods: EBT2 film placed beneath a dual layer 3‐point ORFIT head, neck and shoulder mask was used to test the effect of mask thickness, beam modulation, air gap, and beam obliquity on bolus effect. Mask thickness was varied based on the distribution of 1.6mm Orfilight layer on top of 2 mm Efficast layer. Beam modulation was varied by irradiating the film with an open field (no beam modulation) and a step and shoot field (beam modulation). Air gap between mask and film was varied from 0 to 5mm. Beam obliquity was varied by irradiating the film at gantry angles of 0°, 35°, and 70°.Finally, film strips placed on a Rando phantom under an Orfit mask, in regions of expected high dose, were irradiated using 5 IMRT and 5 VMAT plans with various modulation levels (modulation factor 2 to 5) and the results were compared with those obtained placing OSLDs at the same locations. Results: An 18–34% increase in mask bolus effect was observed for three factors where the effect of beam obliquity ≥ beam modulation &gt; mask thickness. No increase in mask bolus effect was observed for change in air gap. A 6–13% increase in dose due to mask bolus effect was observed on film strips. Conclusion: This work underlines the role of beam obliquity and beam modulation combined with thermoplastic mask thickness in increasing mask bolus‐associated skin dose in head and neck IMRT/VMAT. One possible method of dose reduction, based on knowledge gained from this work, is inclusion of skin as an avoidance structure in treatment planning. Another approach is to design a mask with the least amount of thermoplastic material necessary for immobilization.
