The feasible workspace analysis of a set point control for a cable-suspended robot with input constraints and disturbances (2006)

This paper deals with the characterization of reachable domain of a set-point controller for a cable-suspended robot under disturbances and input constraints. The main contribution of the paper is to calculate the feasible domain analytically through the choice of a control law, starting from a given initial condition. This analytical computation is then recursively used to find a second feasible domain starting from a boundary point of the first feasible domain. Hence, this procedure allows to expand the region of feasible reference signals by connecting adjacent domains through common points. Finally, the effectiveness of the proposed method is illustrated by numerical simulations on a kinematically determined cable robot with six cables.
Optical waveguide Fabry–Perot modulators in LiNbO_3 (1994)

Fabry-Perot-type electro-optic modulators have been produced with Ti:LiNbO(3) optical waveguides. The end mirrors are formed by depositing six pairs of SiO(2) and TiO(2) layers at the waveguide input and output faces. A V(π) of approximately 4 V was measured at 0.81 µm wavelength for the extraordinary polarization in a 7-mm interaction length. Comparison of the modulation performance in the linear region with the modulation performance of a polarization intensity modulator of similar geometry indicates a sensitivity for the Fabry-Perot modulator that is ~3 times larger. The sensitivity can be further improved by using higher reflectance mirrors and reducing waveguide losses.
In-depth quantification by using Multispectral Time-Resolved Diffuse Optical Tomography (2015)

Near-infrared diffuse optical tomography (DOT) is a medical imaging which gives the distribution of the optical properties of biological tissues.To obtain endogenous chromophore features in the depth of a scattering medium, a multiwavelength/time-resolved (MW/TR) DOT setup was used.Reconstructions of the three-dimensional maps of chromophore concentrations of probed media were obtained by using a data processing technique which manages Mellin-Laplace Transforms of their MW/TR optical signals and those of a known reference medium.The point was to put a constraint on the medium absorption coefficient by using a material basis composed of a given set of chromophores of known absorption spectra.Experimental measurements were conducted by injecting the light of a picosecond nearinfrared laser in the medium of interest and by collecting, for several wavelengths and multiple positions, the backscattered light via two fibers (with a source-detector separation of 15 mm) connected to fast-gated single-photon avalanche diodes (SPAD) and coupled to a time-correlated single-photon counting (TCSPC) system.Validations of the method were performed in simulation in the same configuration as the experiments for different combination of chromophores.Evaluation of the technique in real conditions was investigated on liquid phantoms composed of an homogenous background and a 10 mm depth inclusion formed of combination of intralipid and inks scanned at 30 positions and at three wavelengths.Both numerical and preliminary phantom experiments confirm the potential of this method to determine chromophore concentrations in the depth of biological tissues.

Data-Driven Anomaly Recognition for Unsupervised Model-Free Fault Detection in Artificial Pancreas (2018)

The last decade has seen tremendous improvements in technologies for Type 1 Diabetes (T1D) management, in particular the so-called artificial pancreas (AP), a wearable closed-loop device modulating insulin injection based on glucose sensor readings. Unluckily, the AP actuator, an insulin pump, is subject to failures, with potentially serious consequences for subject safety. This calls for the development of advanced monitoring systems, leveraging the unprecedented data availability. This paper tackles for the first time the problem of automatically detecting pump faults with multidimensional data-driven anomaly detection (AD) methodologies. The approach allows to avoid the subtask of identifying a physiological model, typical of model-based approaches. Furthermore, we employ unsupervised methods, removing the need of labeled data for training, hardly available in practice. The adopted data-driven AD methods are local outlier factor, connectivity-based outlier factor, and isolation forest. Moreover, we propose a modification of these methods to cope with the dynamic nature of the underlying problem. The algorithms were tuned and tested on: 1) two-synthetic 100-patients' data set, of one-month data each, generated using the “UVA/Padova T1D Simulator,” a large-scale nonlinear computer simulator of T1D subject physiology, largely adopted in AP research and accepted by the American Food and Drug Administration as a replacement of preclinical animal trials for AP and 2) a real 7-patients' data set consisting of one month in free-living conditions. The satisfactory accuracy of the proposed approach paves the way to the embedding of these methodologies in AP systems or their deployment in remote monitoring systems.
Gain Enhancement of Three-Quarter Wavelength Inverted L-Shaped Antenna in Forward Direction of Metallic Objects or Human Bodies (2018)

The length of an inverted L shaped antenna (ILA) which is three-quarters of the wavelength is studied. The ILA is placed on metallic objects or human bodies. The desired direction of radiation is at right angles to the objects. The gain in this direction without matching loss is enhanced, where the antenna is bent at a point that is approximately a quarter of wavelength from the feeding point. Because the current vector reverses near this bending point, the offsetting of current vectors is avoided and the combined current vector of this bent antenna is longer than that of the unbent antenna and that of the one quarter of wavelength ILA. As a result, the gain of the optimized three-quarters of wavelength ILA is enhanced.
Complexities in the quick analysis and interpretation of microseismic data (2007)

Passive microseismic monitoring offers the promise of a reliable and valuable tool to aid in the diagnosis and control of a hydraulic fracture stimulation program. Timely processing, analysis, and interpretation of microseismic data allows for the adjustment of pumping parameters as the stimulation proceeds, with the aim of improving return on investment. While methods exist today for automated computation and event localization, care needs to be exercised in the quick interpretation of the traditional display, where each event location estimate, is plotted as a single point. We will show an example of data, and highlight some of the limitations of the point source display.
[Basic investigation of data acquisition system for next generation PET scanner]. (2003)

We are under development of a 3D PET scanner with depth of interaction (DOI) capable of high sensitivity and high resolution. In this paper, we estimated the data transfer rate of data acquisition system of this PET scanner by the simulation studies. A maximum data transfer rate of coincidence pair's event information is 10 Mcps and one coincidence event is a 64-bit data format. A data acquisition system, which fulfills the specification of this scanner, is considered for parallel collection with banks including several coincidence units. Simulator of parallel collection system composed of two stand-alone simulators and the server PC. Each stand-alone simulator is composed of data generation PC, data processing circuit, SCSI and data acquisition PC. As the result of simulation studies, the maximum data transfer rate of the stand-alone simulator was 12.0 MB/s, and the maximum data transfer rates at the server PC with one and two nodes were 11.0 and 21.8 MB/s, respectively. Data transfer rate was improved by parameter optimization of a message size and multi-processing of data acquisition software using RAM-DISK.
In vitro killing of human glioblastoma by interleukin-2-activated autologous lymphocytes (1986)

Culture of peripheral blood lymphocytes (PBL) from brain-tumor patients with recombinant interleukin-2 (IL-2) results in the activation of lymphokine-activated killer cells (LAK) with the capacity to lyse autologous and allogeneic glioblastoma. In this study, PBL obtained from brain-tumor patients were cultured with or without IL-2 for 3 to 7 days and then tested for their ability to lyse target cells in a 4-hour chromium release cytotoxicity assay. The PBL were drawn 1 to 2 weeks following operative tumor debulking. Cells used as targets included fresh brain-tumor cells obtained at the time of craniotomy, fresh brain-tumor cells grown from 1 to 3 weeks in tissue culture, fresh autologous PBL, and allogeneic glioblastoma cells grown in tissue culture. Peripheral blood lymphocytes from brain-tumor patients that were cultured without IL-2 did not significantly lyse autologous or allogeneic glioblastoma. However, when these PBL were cultured with IL-2, LAK were generated which produced marked lysis of autologous as well as allogeneic tissue-culture glioblastoma in all of eight cases. Significant lysis of autologous fresh tumor by patient LAK was observed in four of five experiments. By contrast, patient LAK did not kill autologous normal PBL. The ability to generate LAK was not influenced by the patient's age, previous therapy, or the administration of steroids.
xDomain (2009)

A number of research systems have demonstrated the benefits of accompanying each request with a machine-checkable proof that the request complies with access-control policy - a technique called proof-carrying authorization. Numerous authorization logics have been proposed as vehicles by which these proofs can be expressed and checked. A challenge in building such systems is how to allow delegation between institutions that use different authorization logics. Instead of trying to develop the authorization logic that all institutions should use, we propose a framework for interfacing different, mutually incompatible authorization logics. Our framework provides a very small set of primitives that defines an interface for communication between different logics without imposing any fundamental constraints on their design or nature. We illustrate by example that a variety of different logics can communicate over this interface, and show formally that supporting the interface does not impinge on the integrity of each individual logic. We also describe an architecture for constructing authorization proofs that contain components from different logics and report on the performance of a prototype proof checker.
Nonconventional Stereochemical Issues in the Design of the Synthesis of the Vancomycin Antibiotics: Challenges Imposed by Axial and Nonplanar Chiral Elements in the Heptapeptide Aglycons (1998)

Controlling the elements of planar and axial chirality are the principal challenges in the synthesis of the aglycon of vancomycin. Vancomycin is the prototypical member of the glycopeptide family of antibiotics which are effective for the treatment of infections by methicillin-resistant Staphylococcus aureus. The first total syntheses of the vancomycin and eremomycin aglycons provide insight into the influence of structure on kinetic and thermodynamic control of atropselective macrocyclizations.
Executive Summary: Practice Guidelines for the Diagnosis and Management of Aspergillosis: 2016 Update by the Infectious Diseases Society of America (2016)

It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. IDSA considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.
Computer simulations of interferometric imaging with the VLT Interferometer and the AMBER instrument (2000)

We present computer simulations of interferometric imaging with the VLT interferometer and the AMBER instrument. These simulations include both the astrophysical modeling of a stellar object by radiative transfer calculations and the simulation of light propagation from the object to the detector (through atmosphere, telescopes, and the AMBER instrument), simulation of photon noise and detector read- out noise, and finally data processing of the interferograms. The results show the dependence of the visibility error bars on the following observational parameters: different seeing during the observation of object and reference star (Fried parameters r<SUB>0,object</SUB> equals 2.4 m, r<SUB>0,ref.</SUB> equals 2.5 m), different residual tip- tilt error ((delta) <SUB>tt,object</SUB> equals 2% of the Airy disk diameter, (delta) <SUB>tt,ref.</SUB> equals 0.1%), and object brightness (K<SUB>object</SUB> equals 3.5 mag and 11 mag, K<SUB>ref.</SUB> equals 3.5 mag). Exemplarily, we focus on stars in late stages of stellar evolution and study one of its key objects, the dusty supergiant IRC + 10420 that is rapidly evolving on human timescales. We show computer simulations of VLTI interferometry of IRC + 10420 with two ATs (wide-field mode, i.e. without fiber optics spatial filters) and discuss whether the visibility accuracy is sufficient to distinguish between different theoretical model predictions.
Fast decoding for open vocabulary spoken term detection (2009)

Information retrieval and spoken-term detection from audio such as broadcast news, telephone conversations, conference calls, and meetings are of great interest to the academic, government, and business communities. Motivated by the requirement for high-quality indexes, this study explores the effect of using both word and sub-word information to find in-vocabulary and OOV query terms. It also explores the trade-off between search accuracy and the speed of audio transcription. We present a novel, vocabulary independent, hybrid LVCSR approach to audio indexing and search and show that using phonetic confusions derived from posterior probabilities estimated by a neural network in the retrieval of OOV queries can help in reducing misses. These methods are evaluated on data sets from the 2006 NIST STD task.

Normalization of Vital Signs Does Not Reduce the Probability of Acute Pulmonary Embolism in Symptomatic Emergency Department Patients (2012)

Clinicians should not use the observation of normalized vital signs as a reason to forego objective testing for symptomatic patients with a risk factor for PE.
Improved Value of the Gasoline and Fuel Oil Co-Product Fractions Generated by the PNNL/LanzaTech Alcohol-to-Jet Process (Final Report) (2020)

The BETO-funded PNNL collaboration with LanzaTech, Inc. utilizes patented technology to address the need for low aromatic jet fuel blendstocks. The PNNL/LanzaTech alcohol-to-jet (ATJ) process converts ethanol from LanzaTech’s syngas fermentation process to jet-range isoparaffins. The aim of this Cooperative Research Development Agreement (CRADA) project was to improve the commercial viability of the LanzaTech/ PNNL ATJ process by developing two new co-product options. Two Focus Areas (FA) were explored: FA1) Increasing the RON of the lighter-than-jet gasoline fraction above 98; and FA2) Creating a synthetic lubricant base oil from the heavier-than-jet fraction. For FA 1, multiple processing approaches were evaluated, and RONs ranging from 96-100 were obtained, each comprising different processing costs. The most cost effective approach identified was a single-step process and yielded a liquid product of 97. Thus, additional development is required to obtain a RON > 98. We will continue work on this focus area with separate Direct Funding Opportunity (DFO) funding within the DOE-BETO Co-Optima Consortium (expected to begin Q2-FY21). Experimental work will focus on i) increasing single pass conversion to > 50%, and ii) obtaining a > 98 RON product. Technoeconomic analysis performed in this project suggests cost competitiveness provided these technical targets can be met. For FA2, multiple approaches were evaluated for increasing the viscosity index (VI) of the heavier-than-jet fraction to at least 120 in order to meet ASTM specifications for a Group III Base Oil (ASTM D6074). All other ASTM specifications are already met. A viscosity index of 115 was obtained, and with minimal undesirable cracking products. We believe a VI of 115 is about the highest possible from a catalytic approach, per review of the patent literature. In order to further increase the VI to > 120 we believe additives and/or liquid-liquid extraction is required. TEA performed earlier in the project suggests cost competitiveness with market prices assuming cracking byproducts are kept < 10 wt.%. If TEA updated with this additional processing still projects economic feasibility next steps could be taken in a subsequent effort.
Endwall Heat Transfer for a Turbine Blade With an Upstream Cavity and Rim Seal Leakage (2013)

Aerodynamic loss and endwall heat transfer for a turbine blade are influenced by complex vortical flows that are generated at the airfoil-endwall junction. In an engine, those flows interact with clearance gaps between stationary and rotating components, as well as with leakage flow that is designed to exhaust through the gaps. This paper describes experimental measurements of endwall heat transfer for a high-pressure turbine blade with an endwall overlap geometry, as well as an upstream leakage feature that supplied swirled or unswirled leakage relative to the blade. For unswirled leakage, increasing its mass flow increased the magnitude and pitchwise uniformity of the heat transfer coefficient upstream of the blades although heat transfer further into the passage was unchanged. Leakage flow with swirl shifted the horseshoe vortex in the direction of swirl and increased heat transfer on the upstream blade endwall, as compared to unswirled leakage. For a nominal leakage mass flow ratio of 0.75%, swirled leakage did not increase area-averaged heat transfer relative to unswirled leakage. At a mass flow ratio of 1.0%, however, swirled leakage increased overall heat transfer by 4% due to an increase in the strength of the vortical flows.
Knee Stability Controlled by Hamstrings and Functional Knee Brace (2001)

The purpose of this study was to determine the effectiveness of an off-the-shelf functional knee brace on preventing anterior tibial translation in anterior cruciate ligament-deficient knees (ACL-d) with greater than 6 mm of side-to-side difference, and the effect of a 50% maximal voluntary hamstring contraction on knee joint laxity. A therapist experienced in using the Knee Signature System (KSS) screened 14 patients who had been diagnosed arthroscopically with ACL deficiency. Nine patients (8 men, 1 woman; mean age, 32.9 years; mean mass, 75 kg; mean height, 177 cm) met the inclusion criteria. All participants were 240 ± 42 days post injury. Participants in the study were tested with no brace, with brace, and 50% maximal voluntary contraction (MVC) of the hamstrings. The uninjured limb was tested only in the unbraced condition. Repeated measures ANOVA (p ≤ .05) and a Bonferroni post hoc analysis was used to detect specific differences between conditions. Results indicate that a 50% hamstring contraction provided better control of anterior tibial displacement than a functional knee brace under the same loading conditions, but a brace may contribute significantly to reducing anterior displacement when the hamstring force is not sufficient.
Parametric Modeling of Ultrawideband Antennas (2007)

Compared to narrowband antennas, ultrawideband (UWB) antennas have particular characteristics which involve new ways to model them. This paper introduces the use of parametric modeling to efficiently model transfer functions (and associated impulse responses) of UWB antennas, and to determine an equivalent circuit of their input impedance.
Social Search for Efficient Information Location in Mobile Domains (2007)

We present a new approach to social search based on the similarities between and shared interests of users. We argue that the mechanism is very effective in finding the desired information. This makes it particularly suitable for application in the mobile domain, where minimizing data transfer is essential. With the approach we also mitigate handset limitations such as computational limitations, display size and input mode. The approach is implemented on the Nokia 6630 handset I. INTRODUCTION Search has become a major business, and gone from simple content search to content with high value-add: yellow pages, time tables, location services etc. are the standard. Especially content search is designed for the PC; it assumes (free) high- bandwidth internet access, a large display and easy textual input (PC-paradigm). This is evident from the waste of space: the user is given technical details irrelevant to the actual query (e.g., URL), and the description of the hit is rarely informative. In most cases the redundancy is also high. Although this is reduced considerably by clustering and effective visualization, it still uses the PC-paradigm. A fundamental weakness is the position of a result in the list (first, forth); this may vary from day to day Mobile search has so far been a port of the PC paradigm to the handset. Both Yahoo and Google have developed applications that optimize the search results for the display size, and that offer services typical for the mobile device. A major functional deficiency is the lack of integration with basic handset functionalities as phone calls or PIMs. The Nokia Mobile Search application is designed around the phone capabilities. Search results are integrated with the communication capabilities and PIM. This makes it trivial to make a table reservation at the restaurant found in the yellow pages. The search result can also be immediately shared with a friend using MMS. An interesting observation is the different user behavior of
