Transfer Function Estimation in System Identification Toolbox via Vector Fitting (2017)

This paper considers black- and grey-box continuous-time transfer function estimation from frequency response measurements. The first contribution is a bilinear mapping of the original problem from the imaginary axis onto the unitdisk. This improves the numerics of the underlying Sanathanan-Koerner iterations and the more recent instrumental-variable iterations. Orthonormal rational basis functions on the unit disk are utilized. Each iteration step necessitates a minimal state-space realization with these basis functions. One such derivation is the second contribution. System identification with these basis functions yield zero-pole-gain models. The third contribution is an efficient method to express transfer function coefficient constraints in terms of the orthonormal rational basis functions. This allows for estimating transfer function models with arbitrary relative degrees (including improper models), along with other fixed and bounded parameter values. The algorithm is implemented in the tfest function in System Identification Toolbox (Release 2016b, for use with MATLAB) for frequency domain data. Two examples are presented to demonstrate the algorithm performance.

The performances of the novel nozzle-scan coating method (2002)

A novel nozzle-scan coating (NS-coating) method is useful for reducing the coated volume and its cost. We define the (waste-fluid rate) WFR as the ratio of the waste fluid to the fluid supplied on the wafer. In conventional spin-coating, the WFR is about 1500%. In the case of the extrusion-spin coating, the WFR decreases to 203%. But using the NS-coating with low speed and large acceleration, the WFR of the raw materials drastically decreased to 30%. This paper introduces some lithographic performances of NS-coating film of KrF chemical amplified resist that was coated with low WFR condition.
Computer Vision in the Operating Room: Opportunities and Caveats (2020)

Effectiveness of computer vision techniques has been demonstrated through a number of applications, both within and outside healthcare. The operating room environment specifically is a setting with rich data sources compatible with computational approaches and high potential for direct patient benefit. The aim of this review is to summarize major topics in computer vision for surgical domains. The major capabilities of computer vision are described as an aid to surgical teams to improve performance and contribute to enhanced patient safety. Literature was identified through leading experts in the fields of surgery, computational analysis and modeling in medicine, and computer vision in healthcare. The literature supports the application of computer vision principles to surgery. Potential applications within surgery include operating room vigilance, endoscopic vigilance, and individual and team-wide behavioral analysis. To advance the field, we recommend collecting and publishing carefully annotated datasets. Doing so will enable the surgery community to collectively define well-specified common objectives for automated systems, spur academic research, mobilize industry, and provide benchmarks with which we can track progress. Leveraging computer vision approaches through interdisciplinary collaboration and advanced approaches to data acquisition, modeling, interpretation, and integration promises a powerful impact on patient safety, public health, and financial costs.
Physics-based GaN HEMT transport and charge model: Experimental verification and performance projection (2012)

A physics-based compact transport and charge model for GaN HEMTs has been developed. The model includes effects such as self-heating, non-linear access region behavior, electron-phonon interaction etc. The model is validated against fabricated devices and is used to evaluate fT improvements in short channel devices. The model is also a suitable base for GaN FET circuit simulation compact models.
Nondestructive Metrology of Layered Polymeric GRIN Materials Using Optical Coherence Tomography (2012)

Based on swept-source OCT technology, we investigated the unique capability of OCT for nondestructive three-dimensional characterization of the sub-surface textures and layer thickness profiles of layered polymeric GRIN samples in micrometer scale.
Spectral Efficiency of OTFS Based Orthogonal Multiple Access With Rectangular Pulses (2022)

In this paper, we consider Orthogonal Time Frequency Space (OTFS) modulation based multiple-access (MA). We specifically consider Orthogonal MA methods (OMA) where the user terminals (UTs) are allocated non-overlapping physical resource in the delay-Doppler (DD) and/or time-frequency (TF) domain. Well known OMA methods include, i) Guard Band (GB) based MA (GBMA), ii) Interleaved Delay Doppler MA (IDDMA), iii) Interleaved Time Frequency MA (ITFMA). The spectral efficiency (SE) performance of these OMA methods has <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">only</i> been studied for <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ideal</i> transmit and receive pulses. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">With ideal pulses</i> , IDDMA and ITFMA are free from multi-user interference (MUI) and unlike GBMA they <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">do not</i> use guard bands in the DD/TF domain. Since ideal pulses are not realizable, in this paper we study the SE performance of these OMA methods with <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">practical rectangular pulses</i> . For these OMA methods, we derive the expression for the received DD/TF domain symbols at the base station (BS) receiver and the effective DD domain channel matrix when rectangular pulses are used. Study of these expressions reveals the presence of MUI when rectangular pulses are used, although the amount of MUI in IDDMA is observed to be significantly smaller than that in ITFMA. We also derive the expression for the achievable sum SE. Through simulations, for practical values of the received signal-to-noise ratio, we observe that with rectangular pulses the sum SE achieved by the IDDMA method is significantly higher than that achieved by the ITFMA and GBMA methods.
Temperature and density measurements of carbon dioxide using electron beam fluorescence (1997)

The Electron Beam Fluorescence (EBF) technique has been applied to carbon dioxide as a diagnostic to obtain temperature and density measurements, with application to the atmosphere of Mars. A spectroscopic model, which is a function of rotational temperature, for the CO2* Anu -» Xng emission between 337 nm and 339 nm has been developed, including the 100 000, 200 100 and 300 200 symmetric-stretch and four 110 010 Renner-Teller vibrational bands. From the ratio of fluorescence signals of filters centered at 337 nm and 338 nm, temperatures from 200 K to 700 K can be measured with an accuracy of 5 K. A photometric equation is developed which can be used with collected signal levels to measure CO2 densities, which was demonstrated to yield accurate density measurements (S/N = 100) in the atmosphere of Mars below 40 km with acquisition times on the order of 1 msec.

Exploring the dynamics of developmental stages of micropropagated medical cannabis (Cannabis sativa L.) through chemical characterization and optimal plantregeneration (2022)

The usage of medical cannabis (Cannabis sativa L.) for therapeutic purposes has been rising in many countries due to increasing evidence for medicinal benefit and favorable regulatory policies [1]. Cannabinoids, particularly Δ9-tetrahydrocannabinol (THC) and its acidic counterpart tetrahydrocannabinolic acid (THCA) are considered the main bioactive constituents of the plant, though C. sativa is known to produce a wide array of phytochemicals [2]. In line with urgent clinical and research demands, large amounts of plant biomass are required for consistent production of high-quality extracts and isolation of cannabinoids.
The length of Amyloid-β in Hereditary Cerebral Hemorrhage with Amyloidosis, Dutch Type (1996)

In hereditary cerebral hemorrhage with amyloidosis, Dutch type (HCHWA-D), a genetic variant (E22Q) of amyloid beta (Abeta) accumulates predominantly in the small vessels of leptomeninges and cerebral cortex, leading to fatal strokes in the fifth or sixth decade of life. Abeta deposition in the neuropil occurs mainly in the form of preamyloid, Congo red negative deposits, while mature neuritic plaques and neurofibrillary tangles, hallmark lesions in Alzheimer's disease (AD), are characteristically absent. A recent hypothesis regarding the pathogenesis of AD states that Abeta extending to residues 42-43 (as opposed to shorter species) can seed amyloid formation and trigger the development of neuritic plaques followed by neuronal damage in AD. We characterized biochemically and immunohistochemically Abeta from three cases of HCHWA-D to determine its length in vascular and parenchymal deposits. Mass spectrometry of formic acid-soluble amyloid, purified by size-exclusion gel chromatography, showed that Abeta 1-40 and its carboxyl-terminal truncated derivatives were the predominant forms in leptomeningeal and cortical vessels. Abeta 1-42 was a minor component in these amyloid extracts. Immunohistochemistry with antibodies S40 and S42, specific for Abeta ending at Val-40 or Ala-42, respectively, were consistent with the biochemical data from vascular amyloid. In addition, parenchymal preamyloid lesions were specifically stained with S42 and were not labeled by S40, in agreement with the pattern reported for AD, Down's syndrome, and aged dogs. Our results suggest that in HCHWA-D the carboxyl-terminal Abeta heterogeneity is due to limited proteolysis in vivo. Moreover, they suggest that Abeta species ending at Ala-42 may not be critical for the seeding of amyloid formation and the development of AD-like neuritic changes.
Detection of Mycobacterium ulcerans in environmental samples during an outbreak of ulcerative disease (1997)

Mycobacterium ulcerans is an environmental bacterium which causes chronic skin ulcers. Despite significant epidemiological evidence to suggest that water is the source of infection, the organism has never been identified in the environment. Environmental water samples were collected from a small town in which an outbreak of 29 cases had occurred in a 3-year period. These were examined by mycobacterial culture and PCR amplification. Similar to previous studies, M. ulcerans was not cultured from the water samples. However, five samples were positive for M. ulcerans by PCR. These samples were collected from a swamp and a golf course irrigation system within the outbreak area. This is the first time that M. ulcerans has been demonstrated to be present in the environment and supports the postulated epidemiology of disease due to this organism.

Inhibition effect of phosphorus-based chemicals on corrosion of carbon steel in secondary-treated municipal wastewater (2013)

Secondary-treated municipal wastewater (MWW) could supply a viable alternative water resource for cooling water systems. Inorganic salts in the concentrated cooling water pose a great challenge to corrosion control chemicals. In this study, the inhibition effect of 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP), trimethylene phosphonic acid (ATMP) and 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) on corrosion of carbon steel in secondary-treated MWW was investigated by the means of potentiodynamic polarization and electrochemical impedance spectroscopy. The inhibition effect increased with increasing concentration of inhibitors. The corrosion rates of carbon steel were 1.5, 0.8, 0.2 and 0.5 mm a(-1) for blank, HEDP, ATMP and PBTCA samples at 50 mg L(-1), respectively. The phosphorus-based chemicals could adsorb onto the surface of the carbon steel electrode, form a coat of protective film and then protect the carbon steel from corrosion in the test solution.
Diameter Group Signaling (2023)

In large network deployments, a single Diameter node can support over
a million concurrent Diameter sessions. Recent use cases have revealed
the need for Diameter nodes to apply the same operation to a large
group of Diameter sessions concurrently. The Diameter base protocol
commands operate on a single session so these use cases could result
in many thousands of command exchanges to enforce the same operation
on each session in the group. In order to reduce signaling, it would
be desirable to enable bulk operations on all (or part of) the
sessions managed by a Diameter node using a single or a few command
exchanges. This document specifies the Diameter protocol extensions to
achieve this signaling optimization.
Quantification in Echocardiography (2006)

Until recently, more than 2200 Swan Ganz catheters were used annually in the operating rooms (OR) and intensive care unit (ICU) of the Catharina Hospital in Eindhoven, The Netherlands. After cardiologists who were specialists in echocardiography (ECHO) trained anesthesiologists in ECHO, the need for these catheters in cardiac and noncardiac surgery was reduced. Initially intended as a local teaching project, an ECHO teaching compact disk (CD) was produced during the training and distributed later worldwide, thanks to a positive review in a major anesthesiology publication. By reducing the number of Swan Ganz catheters, the hospital could finance and acquire two echocardiography machines for the OR and ICU. The availability of these machines resulted in a further reduction of the number of Swan Ganz catheters. However, the need for quantification (eg, measurements of cardiac output) remained. During the creation of the ECHO teaching CD, the idea was born to apply indicator-dilution principles on injected echo contrast. This study was performed in cooperation with the Signal Processing Department of the Eindhoven University of Technology. Advanced signal processing and modelling were used to develop algorithms to enable quantification of intrapulmonary blood volume, ejection-fraction, and flow from the transesophageal echocardiography approach. These quantitative measurements, which can be performed on an outpatient basis, may become a real asset in cardiology, anesthesiology, and intensive care.
Laterally vibrating lithium niobate MEMS resonators with high electromechanical coupling and Quality factor (2012)

This paper reports on a new type of laterally vibrating micro-resonators (LVRs) enabled by ion sliced X-cut Lithium Niobate thin film and micro-machining. In operation, the device is excited into lateral vibrations, thus allowing the center frequency to be determined by the lithography-defined dimensions of the electrodes. This configuration enables monolithic multi-frequency solutions for future wireless communication. The designed devices have shown a high electromechanical coupling (k <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) of 11% - the highest demonstrated for MEMS LVRs.

Defining a Safety Margin for Labral Suture Anchor Insertion Using the Acetabular Rim Angle (2011)

Surgeons should be aware of the acetabular rim variations, especially in the anterosuperior quadrant, as well as the effects of drill depth and rim trimming, when selecting the optimal insertion angle for suture anchor placement to avoid articular cartilage penetration. The acetabular safety angle was smallest at the 3-o'clock position. Therefore, extra care must be taken when drilling or inserting anchors around the 3-o'clock position.
Disease progression in multiple sclerosis: combining physicians’ and patients’ perspectives? (2010)

When assessing disease progression in MS, sensitivity to change can be increased by combining different outcome measures. The added value is especially present when combining measures from different perspectives. However, further research is needed to evaluate the optimal way to combine outcome measures before implementing this strategy in clinical studies.
The Whole Brain Activity Map: Merging Nanoscience and Neuroscience for Technology and Health (2011)

The ultimate goal of this project is to construct the functional connectome map of the human brain, by assembling a coordinated network of researchers deploying next—generation nanotechnological tools with unprecedented capabilities. Mapping the functional connectome will unravel the fundamental, long-sought paradigms of how the brain computes. Together with these new technologies, this will enable accurate diagnosing, and restoring, of normal patterns of activity to injured or diseased brains; will foster the development of broader biomedical and environmental applications; and will produce a host of associated economic benefits.
An Entity-Focused Approach to Generating Company Descriptions (2016)

Finding quality descriptions on the web, such as those found in Wikipedia articles, of newer companies can be difficult: search engines show many pages with varying relevance, while multi-document summarization algorithms find it difficult to distinguish between core facts and other information such as news stories. In this paper, we propose an entity-focused, hybrid generation approach to automatically produce descriptions of previously unseen companies, and show that it outperforms a strong summarization baseline.

Corvo: Visualizing CellxGene Single-Cell Datasets in Virtual Reality (2022)

The CellxGene project has enabled access to single-cell data in the scientific community, providing tools for browsed-based no-code analysis of more than 500 annotated datasets. However, single-cell data requires dimensional reduction to visualize, and 2D embedding does not take full advantage of three-dimensional human spatial understanding and cognition. Compared to a 2D visualization that could potentially hide gene expression patterns, 3D Virtual Reality may enable researchers to make better use of the information contained within the datasets. For this purpose, we present \emph{Corvo}, a fully free and open-source software tool that takes the visualization and analysis of CellxGene single-cell datasets to 3D Virtual Reality. Similar to CellxGene, Corvo takes a no-code approach for the end user, but also offers multimodal user input to facilitate fast navigation and analysis, and is interoperable with the existing Python data science ecosystem. In this paper, we explain the design goals of Corvo, detail its approach to the Virtual Reality visualization and analysis of single-cell data, and briefly discuss limitations and future extensions.
