Clinical Significance of Heparin-Binding Epidermal Growth Factor–Like Growth Factor and A Disintegrin and Metalloprotease 17 Expression in Human Ovarian Cancer (2005)

Our findings suggest that HB-EGF and ADAM 17 contribute to the progression of ovarian cancer and that HB-EGF plays a pivotal role in the aggressive behavior of a tumor in ovarian cancer.
Localization of miniature mobile robots using constant curvature dynamic contours (2003)

Presents a method for localizing miniature mobile robots (Scouts) using dynamic contours. An observer robot with a camera follows the miniature robot as it moves and jumps in the workspace. Dynamic contours are very effective in tracking the fast accelerations and decelerations of the Scout robot. We show initial experimental results with particular emphasis on the task of monitoring a Scout during jumps.
Effect of water adsorption onto the polymer layer produced from the monomer carrying amide group in liquid crystal cells (2016)

The voltage holding ratio (VHR) of an active-matrix liquid crystal display (AMLCD) is a significant parameter because the image quality of the AMLCD decreases in case of low VHR. In some cases, the VHR of the LC cell, which is a prototype of the AMLCD, is decreased under an environment of high humidity and temperature. In order to restrict the significant decrease in the VHR, we proposed an LC cell with the polymer layer produced from the monomer 1-acryloyl-oxy-5-acryloyl-amino-naphthalene (1-AO-5-AANp). The LC cell exhibited comparably high VHR after being placed in an environment of high humidity and temperature. We presume that water molecules would be effectively adsorbed onto the polymer layer carrying the amide group, leading to a restriction of the significant decrease in VHR.
Simultaneous all-optical demultiplexing of a 40-Gb/s signal to 4 x 10 Gb/s WDM channel's using an ultrafast fiber wavelength converter (2002)

We demonstrate simultaneous demultiplexing of a 40-Gb/s optical time division multiplexed stream to four 10-Gb/s data streams, each on a different wavelength, using a single ultrafast nonlinear fiber wavelength converter. The wavelength converter employs cross-phase modulation in a dispersion-shifted fiber and utilizes control pulses generated at four wavelengths by a single electroabsorption modulator. This technique can be scaled to demultiplex a very high bit-rate signal to multiple wavelength division multiplexed channels simultaneously using just one electroabsorption modulator and one fiber based wavelength converter. Additionally broad control pulses with limited extinction ratio do not adversely affect the performance of the demultiplexer. For a control pulsewidth of 11-12 ps, the measured power penalty is <1.5 dB. Increasing the control pulsewidth to 14 ps incurs an additional power penalty of only 0.5 dB.
Link State Protocol Data Mining for Shared Risk Link Group Detection (2010)

In this paper, we use machine learning technique at the routers to study the link state protocol data to predict the existence of shared risk link groups (SRLG) in the network. In particular, we use the correlation between different link state updates (LSUs) issued by different network nodes (routers) upon failure. The concerned network router then runs a novel Bayesian network based statistical learning process to learn about the possible existence of SRLGs. The decision of this online learning is transferred to the routing information base (RIB) so that it can accordingly modify the routing table for the entire SRLG upon failure detection of one of the candidate node of that particular SRLG and hence reduce the protection switching time.
Two-year clinical evaluation of a self-adhesive luting agent for ceramic inlays. (2010)

The self-adhesive resin cement RelyX Unicem showed acceptable clinical behavior after two years of clinical service. Selective enamel etching prior to luting had no significant influence on marginal integrity, inlay integrity, tooth integrity, sensitivity or complications of the restored teeth after 24 months. Longer term evaluation is needed to confirm this finding.
Preferential coupling of an incident wave to reflection eigenchannels of disordered media (2015)

Light waves incident to a highly scattering medium are incapable of penetrating deep into the medium due to the multiple scattering process. This poses a fundamental limitation to optically imaging, sensing, and manipulating targets embedded in opaque scattering layers such as biological tissues. One strategy for mitigating the shallow wave penetration is to exploit eigenchannels with anomalously high transmittance existing in any scattering medium. However, finding such eigenchannels has been a challenging task due to the complexity of disordered media. Moreover, it is even more difficult to identify those eigenchannels from the practically relevant reflection geometry of measurements. In this Letter, we present an iterative wavefront control method that either minimizes or maximizes the total intensity of the reflected waves. We proved that this process led to the preferential coupling of incident wave to either low or high-reflection eigenchannels, and observed either enhanced or reduced wave transmission as a consequence. Since our approach is free from prior characterization measurements such as the recording of transmission matrix, and also able to keep up with sample perturbation, it is readily applicable to in vivo applications. Enhancing light penetration will help improving the working depth of optical sensing and treatment techniques.
Pseudorapidity dependence of the anisotropic flow of charged particles in Pb–Pb collisions at sNN=2.76 TeV (2016)

We present measurements of the elliptic (v 2 ), triangular (v 3 ) and quadrangular (v 4 ) anisotropic azimuthal flow over a wide range of pseudorapidities (-3.5 < < 5). The measurements are performed with Pb-Pb collisions at s NN = 2.76 TeV using the ALICE detector at the Large Hadron Collider (LHC). The flow harmonics are obtained using two-and four-particle correlations from nine different centrality intervals covering central to peripheral collisions. We find that the shape of v n () is largely independent of centrality for the flow harmonics n = 2-4, however the higher harmonics fall off more steeply with increasing ||. We assess the validity of extended longitudinal scaling of v 2 by comparing to lower energy measurements, and find that the higher harmonic flow coefficients are proportional to the charged particle densities at larger pseudorapidities. Finally, we compare our measurements to both hydrodynamical and transport models, and find they both have challenges when it comes to describing our data.

Microcalcification segmentation and mammogram image enhancement using nonlinear filtering. (1999)

Microcalci cations are tiny calcium deposits in breast tissues. They appear as small bright spots on mammograms. Since microcalci cations are small and subtle abnormalities, they maybeoverlooked by an examining radiologist. In this work, we propose microcalci cation segmentation and mammogram enhancement methods based on nonlinear subband decomposition structures and outlier detection. The mammogram image is rst processed by a nonlinear lter bank, then the locations of the outliers are determined by outlier labeling method. The proposed method can also be used in the three-dimensional reconstruction of microcalci cation clusters. Simulation studies are presented. 1.
Type identification of autosomal dominant polycystic kidney disease by analysis of fluorescent short tandem repeat markers. (2002)

Autosomal dominant polycystic kidney disease (ADPKD), is an inherited disorder with genetic heterogeneity. The presence of renal cysts is an important clinical marker for ADPKD diagnosis, but in the early stage, renal cysts do not emerge in individuals who carry the defective gene. Therefore, it is necessary to establish a genetic method of diagnosis. Two ADPKD-related genes have been isolated: PKD1, located on chromosome 16p13.3, and PKD2, located on 4q21-22. In this study, we used fluorescent short tandem repeat (STR) markers to perform linkage analysis in six unrelated ADPKD families. Six markers were included in the PKD1 and five in the PKD2 analysis. Among these six ADPKD families, four showed linkage to PKD1 and two showed linkage to PKD2. Ultrasonography or computerized tomography revealed that PKD1 patients developed cysts only in kidneys, but PKD2 patients developed cysts in kidneys, liver and pancreas. Our results indicate that fluorescent STR linkage analysis is well suited for type identification of ADPKD and presymptomatic diagnosis in ADPKD families.
Ph-Sensitive Polymeric Nanoparticles for Tumor-Targeting Doxorubicin Delivery: Concept and Recent Advances (2014)

Doxorubicin is a potent chemotherapeutic drug applied in the clinics for the treatment of various human cancers. It is typically administered as the hydrochloride salt or in liposomal forms, which are plagued with severe side effects. In recent years, pH-sensitive polymeric nanoparticles that are capable of retaining drug during circulation while actively releasing it at the tumor site and/or inside the target tumor cells have received an overwhelming interest for tumor-targeting cancer chemotherapy. This smart delivery approach has shown to elegantly resolve the in vivo stability versus intracellular drug release dilemma, as well as stealth versus tumor cell uptake dilemma. In this review, the concept and exciting new advances in pH-sensitive polymeric nanoparticles for doxorubicin delivery are presented and discussed.
On-Chip Microdialysis System With In-Line Sensing Capabilities (2005)

Microdialysis probes have been used for diabetes treatment as continuous monitoring system coupled to a glucose sensor. An on-chip microdialysis system with in-line sensing electrodes is demonstrated. The response time of the microdialysis system was characterized and the permeability of the polycarbonate membrane (100nm pore size) to glucose was determined to be 2.53 μm/s (std:0.372 μm/s). As a first step towards greater biosensor integration with this miniaturized microdialysis system, a stacked system with in-line sensing electrodes was developed. Impedance electrodes within the microchannels were used to determine fluid resistance from a dialyzed phosphate buffered saline (PBS) solution, which characterizes solution conductivity as a function of PBS concentration. The permeability of the membrane to the salt ions was obtained as 0.74 μm/s (15 nm pores). Subsequently, experiments measuring PBS dialysis in the time-domain at 60% recovery were conducted. The PBS concentration of the reservoir was changed in either a step response or sinusoidally with an 800 second period. The subsequently measured impedance indicates that the system is able to continuously track concentration changes in the reservoir with a 180 second system response delay. Most of this delay is due to the dead volume within the tubing between the syringe pumps and the microsystem In addition the predicted response was modeled using linear systems theory and matches the experimental measurements. This system is expected to have the proper sensitivity to track physiologically relevant concentration changes of biomolecules such as glucose (which has a physiological maximum change rate of ~4mg/dL-min with a periodicity of 1 hour or greater) with minimal lag time and amplitude reduction.
Text and Style Conditioned GAN for Generation of Offline Handwriting Lines (2020)

This paper presents a GAN for generating images of handwritten lines conditioned on arbitrary text and latent style vectors. Unlike prior work, which produce stroke points or single-word images, this model generates entire lines of offline handwriting. The model produces variable-sized images by using style vectors to determine character widths. A generator network is trained with GAN and autoencoder techniques to learn style, and uses a pre-trained handwriting recognition network to induce legibility. A study using human evaluators demonstrates that the model produces images that appear to be written by a human. After training, the encoder network can extract a style vector from an image, allowing images in a similar style to be generated, but with arbitrary text.

Minimal Invasive Decompression for Lumbar Spinal Stenosis (2012)

Lumbar spinal stenosis is a common condition in elderly patients and may lead to progressive back and leg pain, muscular weakness, sensory disturbance, and/or problems with ambulation. Multiple studies suggest that surgical decompression is an effective therapy for patients with symptomatic lumbar stenosis. Although traditional lumbar decompression is a time-honored procedure, minimally invasive procedures are now available which can achieve the goals of decompression with less bleeding, smaller incisions, and quicker patient recovery. This paper will review the technique of performing ipsilateral and bilateral decompressions using a tubular retractor system and microscope.
Human brain trauma severity is associated with lectin complement pathway activation (2018)

We explored the involvement of the lectin pathway of complement in post-traumatic brain injury (TBI) pathophysiology in humans. Brain samples were obtained from 28 patients who had undergone therapeutic contusion removal, within 12 h (early) or from >12 h until five days (late) from injury, and from five non-TBI patients. Imaging analysis indicated that lectin pathway initiator molecules (MBL, ficolin-1, ficolin-2 and ficolin-3), the key enzymes MASP-2 and MASP-3, and the downstream complement components (C3 fragments and TCC) were present inside and outside brain vessels in all contusions. Only ficolin-1 was found in the parenchyma of non-TBI tissues. Immunoassays in brain homogenates showed that MBL, ficolin-2 and ficolin-3 increased in TBI compared to non-TBI (2.0, 2.2 and 6.0-times) samples. MASP-2 increased with subarachnoid hemorrhage and abnormal pupil reactivity, two indicators of structural and functional damage. C3 fragments and TCC increased, respectively, by 3.5 - and 4.0-fold in TBI compared to non-TBI tissue and significantly correlated with MBL, ficolin-2, ficolin-3, MASP-2 and MASP-3 levels in the homogenates. In conclusion, we show for the first time the direct presence of lectin pathway components in human cerebral contusions and their association with injury severity, suggesting a central role for the lectin pathway in the post-traumatic pathophysiology of human TBI.
HPLC/Mass Spectrometry and HPLC/MS/MS/ methods for the detection of Multiple Ciguatoxins (1999)

High performance liquid chromatography (HPLC) / mass spectrometry (MS) was used to identify ciguatoxins and ciguatoxin congeners present in the viscera of ciguateric moray eels (Gymnothorax javanicus) collected in the central Pacific Ocean (P-CTX) and in the flesh and viscera of ciguateric horse eye jack (Caranx latus) of the Caribbean Sea (C-CTX). Multiple ciguatoxin congeners were identified from each source. To improve the sensitivity of detection, HPLC coupled to tandem ionspray MS (MS/MS) methods were developed that detected sub-ppb levels of C-CTX-I and P-CTX-I. Partially purified fish extracts spiked with pure P-CTX-I and C-CTX-1 were subjected to reverse phase HPLC and the ciguatoxins present quantified by MS/MS. HPLC/MS/MS proved a sensitive method, not previously available, for the specific analysis of CTX and related toxins at levels in fish below those that cause human poisoning. These MS-based detection methods will facilitate (I) the development of rapid detection methods designed to screen potentially toxic fish before sale and (II) the study of the biotransformation of CTXs that pass through the marine food chain.
A Reconfigurable Dual-Frequency Narrowband CMOS LNA Using Phase-Change RF Switches (2017)

This paper presents a dual-band low-noise amplifier (LNA) that can be reversibly configured between 3 and 5 GHz using a phase-change (PC) RF switch. Simultaneous noise and conjugate input matching is achieved at the two frequencies using a single PC RF switch and coupled source inductors, thereby minimizing integration complexity and enabling a compact design roughly equal in size to a single-band design. The PC switch has extremely low on-state resistance (1.5-4Ω) and parasitic capacitance (12-16 fF), and has a compact footprint (~50 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ). A chip containing the PC switch is fabricated in-house while the rest of the LNA is fabricated in a 0.13-μm CMOS technology. The two chips are combined using an in-house flip-chip integration process. Characterization from five prototypes fabricated in two batches is presented. The integrated LNAs achieved peak gain greater than 20 dB and minimum noise figure less than 2.9 dB in both the frequency bands while consuming a peak power of 7.2 mW from a 1.2-V supply. Comparison of the CMOS-PC prototypes with carefully designed control LNAs demonstrates the effectiveness of the PC switch for RF reconfiguration, which allows the reconfigurable LNA to achieve performance comparable to its nonreconfigurable counterparts.

Assessment of the Energy Impacts of Outside Air in the Commercial Sector (2009)

The enormous quantity of energy consumed by U.S. commercial buildings places a significant burden on the energy supply and is a potential source of economic strain. To address this, the DOE Building Technologies Program has established the goal of developing market-viable zero energy buildings by 2025. This study focuses on the effects of outside air, and considers various outside air sources, types of building construction, building subsectors, and climates. Based on the information about energy consumption attributed to outside air, it identifies topics for further research that have the greatest potential to achieve energy savings.
Absolute calibration for complex-geometry biomedical diffuse optical spectroscopy (2013)

We have presented methodology to calibrate data in NIRS/MRI imaging versus an absolute reference phantom and results in both phantoms and healthy volunteers. This method directly calibrates data to a diffusion-based model, takes advantage of patient specific geometry from MRI prior information, and generates an initial guess without the need for a large data set. This method of calibration allows for more accurate quantification of total hemoglobin, oxygen saturation, water content, scattering, and lipid concentration as compared with other, slope-based methods. We found the main source of error in the method to be derived from incorrect assignment of reference phantom optical properties rather than initial guess in reconstruction. We also present examples of phantom and breast images from a combined frequency domain and continuous wave MRI-coupled NIRS system. We were able to recover phantom data within 10% of expected contrast and within 10% of the actual value using this method and compare these results with slope-based calibration methods. Finally, we were able to use this technique to calibrate and reconstruct images from healthy volunteers. Representative images are shown and discussion is provided for comparison with existing literature. These methods work towards fully combining the synergistic attributes of MRI and NIRS for in-vivo imaging of breast cancer. Complete software and hardware integration in dual modality instruments is especially important due to the complexity of the technology and success will contribute to complex anatomical and molecular prognostic information that can be readily obtained in clinical use.
Magnetization Transfer Ratio Imaging in Multiple Sclerosis: a Comparison of 3D Balanced Steady-State Free Precession and 2D Gradient Echo Sequences in Clinical Studies (2008)

There is great need for techniques, that quantitatively assess subtle tissue changes beyond the gross pathology in multiple sclerosis. We evaluated a new 3DbSSFP MTR protocol yielding maximal sensitivity to MT in human brain. We compared this 3D-bSSFP with the commonly used 2D-GRE approach in a clinical setup, and evaluated the advantages of bSSFP in a quantitative study on 20 MS patients. Protocols were adjusted to similar acquisition times while using optimized sequence settings for both approaches. Higher, and esp. isotropic resolution, whole brain coverage, and stronger grey-white matter MTR contrast turned out to be the important advantages of 3D-bSSFP.
