Omnidirectional reflective contacts for light-emitting diodes (2003)

An electrically conductive omnidirectional reflector (ODR) is demonstrated in an AlGaInP light-emitting diode (LED). The ODR serves as p-type contact and comprises the semiconductor, a metal layer and an intermediate low-refractive index dielectric layer. The dielectric layer is perforated by an array of AuZn microcontacts thus enabling electrical conductivity. It is shown that the ODR significantly increases light extraction from an AlGaInP LED as compared to a reference LED employing a distributed Bragg reflector (DBR). External quantum efficiencies of 18% and 11% are obtained for the ODR- and the DBR-LED, respectively.
307. The effect of oxytocin on cell growth and steroid production in normal human prostate cells in vitro (2005)

Oxytocin (OT) is present in reproductive tissues of male mammals including human prostate tissue. OT increases prostatic muscle tone and prostatic growth. OT is increased in benign prostatic hyperplasia (BPH), an androgen dependent condition that develops with age. Dihydrotestosterone (DHT) is the active hormone in the prostate and is converted from testosterone by the enzyme 5 a reductase. Conversion has been shown to be augmented in the presence of OT. The aim of this study was to investigate the effect of oxytocin on cell growth and steroid production in cultured normal human prostate cells. Normal human prostate stromal and epithelial cells (Clonetics) were cultured with OT, oxytocin antagonist (OTA) or oxytocin/oxytocin antagonist combination (10 ng/mL, 1 ng/mL or 0.1 ng/mL) in media containing 10 nmol of testosterone. Media was changed daily over the 5 day growth period and frozen. Cell proliferation assay was performed at harvest on day 5 to ascertain cell numbers. Media from days 1, 3 and 5 were extracted and radioimmunoassayed for testosterone and DHT. OT increased stromal cell number in a dose dependent manner (P < 0.001). Treatment with OT or OTA had no significant effect on epithelial cell numbers. In stromal cell media from Day 1, DHT concentrations were higher in cells treated with OT than control cells (P < 0.05). By Day 5 the concentration of DHT was low in all treatment groups except OT (10 ng/mL). No effect of OT or OTA was seen on DHT concentrations of media from epithelial cells. OT may increase cell growth in prostate stromal cells but not epithelial cells grown in vitro. This effect may be related to the conversion of testosterone to DHT and DHT to its metabolites. These results demonstrate that OT may play a role in the regulation of cell growth, steroid production and steroid metabolism in the human prostate.

A 48-well transparent microelectrode array fabricated utilizing a flexible, “wrapped around” interconnect technology (2016)

This paper describes the microfabrication, assembly and preliminary characterization of a flexible multi-layer circuit wrapped around a base plate utilized as a high-throughput 48-well Microelectrode Array (MEA) device. Roll to roll flexible circuit technology allows for fine lines and spaces (<;25 μm) to be fabricated in a large area fashion and has been exploited for the first time to our knowledge toward a high-throughput MEA application. Utilizing this technology to develop a microelectrode array has the opportunity to provide cost-effective, disposable consumable devices to the high-throughput biotechnology and biosensor screening markets. The flexibility allows for the circuit to be wrapped around a rigid substrate, thereby allowing backside interconnectivity and eliminating the need for expensive conductive through vias and lowering the number of processing steps. This device has been further assembled and characterized.
Interactions between Oxidative Stress, Lipid Profile and Antioxidants in Breast Cancer: A Case Control Study (2012)

Oxidant/antioxidant balance has been suggested as an important factor for initiation and progression of cancer. The objective of this study was to determine changes in the levels of malondialdehyde (MDA), nitric oxide (NO), total cholesterol, triglycerides, LDL-cholesterol, HDL-cholesterol, total antioxidant capacity (TAC), glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) activities in serum samples of breast cancer patients (n=30) and healthy subjects (n=100). MDA and NO levels were found to be increased in breast cancer patients compared to the healthy subject group (p<0.05). Total cholesterol and triglycerides were elevated; and HDL- cholesterol level was found to be decreased in the cancer patients as compared to the healthy subjects (p<0.05). Compared to the healthy group, both serum TAC levels (p<0.001) and activity of SOD and GSH-Px (p=0.05) were found to be decreased in the breast cancer patients as compared to the healthy controls. Considering the data presented in this study, we suggest that free radicals induce lipid eroxidation and peroxidation of unsaturated fatty acid with decreased activity of enzymatic antioxidants in breast cancer.
A guided tour of the Trans‐Proteomic Pipeline (2010)

The Trans-Proteomic Pipeline (TPP) is a suite of software tools for the analysis of MS/MS data sets. The tools encompass most of the steps in a proteomic data analysis workflow in a single, integrated software system. Specifically, the TPP supports all steps from spectrometer output file conversion to protein-level statistical validation, including quantification by stable isotope ratios. We describe here the full workflow of the TPP and the tools therein, along with an example on a sample data set, demonstrating that the setup and use of the tools are straightforward and well supported and do not require specialized informatic resources or knowledge.

Pair-Matching Method for Estimating 2-D Angle of Arrival With a Cross-Correlation Matrix (2006)

This letter presents a novel method for pair matching of elevation and azimuth angles in two-dimensional (2-D) angles-of-arrival estimation employing two uniform linear arrays (ULAs). The proposed pair-matching method exploits the cross-correlation matrix of two received signals impinging on each ULA that shows the characteristics of the corresponding angle pairs, and is conducted by combining it with a propagator method. Numerical simulations using L-shaped array geometry revealed that the proposed method provided better robustness over the SNR, angular separation, and number of sources than that of conventional methods.
Evaluation of a belief-network-based reminder system that learns from utility feedback. (1995)

PRETRIEVE is a belief-network-based, unsolicited information-retrieval system that performs machine learning based on user feedback. We report here on the document-ordering and document-retrieval performance of PRETRIEVE. We developed a test collection of 410 judgments of document utility in a simulated medical order-entry context. We characterized the validity of these judgments, which were elicited from domain experts, by measuring interrater and intrarater reproducibility. We developed a measure of the quality of document orderings similar to the ROC-curve analysis used to evaluate document-retrieval systems. We found that the ordering performance of the PRETRIEVE system was (1) substantially better than random, (2) somewhat less than ideal, and (3) superior to that of versions of the PRETRIEVE system that used relevance feedback instead of utility feedback. Under a set of assumptions, which we make explicit, we found that the documents retrieved by a version of PRETRIEVE that modeled time cost were of higher utility than those retrieved by a similar rule-based system.
Determination of <i>D</i>- and <i>L</i>-Pipecolic Acid in Food Samples Including Processed Foods (2003)

These findings suggest that plasma pipecolic acid, particularly the D-isomer, does not originate from direct food intake and that D- and L-pipecolic acid can possibly be derived from intestinal bacterial metabolites.
Real-time Interrogation of Fiber Bragg Grating Sensors Based on Chirped Pulse Compression (2011)

Theoretical and experimental studies of real-time interrogation of fiber Bragg grating (FBG) sensors based on chirped pulse compression with increased interrogation resolution and signal-to-noise ratio are presented. Two interrogation systems are proposed in this thesis. In the first interrogation system, a linearly chirped FBG (LCFBG) is employed as the sensing element. By incorporating the LCFBG in an optical interferometer as the sensor encoding system, employing wavelength-to-time mapping and chirped pulse compression technique, the correlation of output microwave waveform with a chirped reference waveform would provide an interrogation result with high speed and high resolution. The proposed system can provide an interrogation resolution as high as 0.25 μ at a speed of 48.6 MHz. The second interrogation system is designed to achieve simultaneous measurement of strain and temperature. In this system, a high-birefringence LCFBG (Hi-Bi LCFBG) is employed as a sensing element.
Ion-exchanged glass waveguides: a review (1988)

Passive glass waveguides made by ion-exchange technique are potential candidates for integrated optics (IO) applications. The authors review the advantages in the technology as applied to fabrication of useful single-mode structures. Progress in process, fabrication, modeling, and waveguide performance using different monovalent cation systems and glass compositions is described with emphasis on fiber-compatible single-mode structures prepared from molten baths. It is shown how a systematic study allows a correlation between the process parameters and the waveguide characteristics so desirable in assuring reproducible characteristics of the devices.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
PyRTL in Early Undergraduate Research (2019)

Undergraduate research experiences are a promising way to broaden participation in computer architecture research and have been shown to improve student learning, engagement, and retention. These outcomes can be more profound and lasting if students experience research early. However, there are many barriers to early research in computer architecture some of which include the gap between pedagogy and research, the lower emphasis on hardware design compared to software in first year courses, and the lack of online resources. We propose lowering these barriers through a methodical approach by involving undergraduates in early research and by creating freely available and innovative educational tools for designing hardware.
Aging Monitoring Method for Lithium-Ion Batteries Using Harmonic Analysis (2020)

Monitoring the aging battery cells is important to maintain battery performance. Capacity is a key indicator of battery aging diagnosis, but capacity can be estimated differently depending on the C-rate. Battery impedance monitoring using electrochemical impedance spectroscopy (EIS) is also recognized as a battery diagnostic method. However, EIS is inefficient when diagnosing a large number of individual battery cells due to complex computation and measurement time. In this article, a harmonic analysis method for monitoring aging battery is proposed. The proposed diagnostic technique applies the designed 1-kHz sinusoidal signal, comprising a sinusoidal current component and a direct current component, to the battery. Harmonics are generated when signals passing through nonlinear systems are distorted. A battery is an asymmetric nonlinear system with different bidirectionality. Comparing the simulation and experimental results, we confirmed that the harmonic signatures are the indicators that distinguish between a normal and an aging battery. Moreover, the proposed in situ technique can be applied during charge/discharge cycles, even in the case of an apparent reduction of even harmonics.
Lapping modeling of looped warp knitted jacquard fabrics based on web (2020)

In this paper a mathematical model of looped warp knitted jacquard fabric is proposed. The technology parameters cover chain notation, threading, jacquard pattern grid and so on are defined based on the matrix. A basic pattern matrix is derived from chain notation and threading using the block matrix. Then combined with the displacement data of jacquard girds, the jacquard pattern matrix is calculated. Finally, the stitch type and stitch position are obtained analyzing the pattern information in the previous matrix. Special stress is laid on the difference between two different displacement data of jacquard girds, RT = 0 and RT = 1, which results in inconsistent lapping for the same jacquard bitmap. The pattern models are implemented and the jacquard lapping bitmap and three-dimensional simulation are generated by a calculating program via Visualstudio2015 using C# and JavaScript. The results show that this model can distinguish two types displacement jacquard information. The parameter input process is simplified and the run time for calculation is also shortened. In addition, with the help of CAD system via the web, priorities including resource sharing, design-time saving, and efficiency improving are achieved.

A 90nm Passive RFID Tag's Custom Baseband Processor for Subthreshold Operation Below 0.3V (2017)

In the design of passive Radio frequency (RF) tags' baseband processor, subthreshold timing and wide-range-Process, voltage and temperature (PVT) variation problems are the bottlenecks to extend the tag's working range. A sophisticated processor is presented based on the EPC and ISO protocol. Power-aware ideas are applied to the entire processor, including data link portions. Innovatively, a novel custom ratioed logic style is adopted in critical logic paths to fundamentally speed up the circuit operations at ultra-low-voltage. The proposed baseband processor was fabricated in 90nm CMOS, another baseband processor design by regular standard-cell-based design flow was also fabricated for comparison. In measurement the proposed design indicates good robustness in wide-range supply and frequency variation and much more competent for subthreshold operation. It can operate at minimum 0.28V supply with power consumption of 129nW.
Polarization Retaining Single-Mode Fiber With Improved Coil Performance (1986)

High birefringence, polarization retaining single-mode optical waveguides have been developed for applications requiring stable performance when the fiber is coiled. Recent designs employing high-expansion aluminum-doped stress rods have demonstrated polarization holding parameters better than 6.0 x 10-6m-1 with little degradation of h-parameter or attenuation down to 2 cm diameter coil configurations.
Magnetic and crystallographic properties of novel Fe-rich rare-earth nitrides of the type RTiFe11N1−δ (invited) (1991)

We succeed in inserting a number of nitrogen atoms into the RTiFe11 intermetallics. The nitrides retain the ThMn12-type structure, but with an increase in the unit cell volume. The crystallographic sites located by nitrogen atoms are determined by using neutron diffraction techniques. The nitrogen atoms are found to have an effect of increasing Curie temperature and saturation magnetization. Moreover, an essential change in magnetocrystalline anisotropy is observed upon nitrogenation. By all of these effects, the NdTiFe11N1−δ compounds have excellent intrinsic magnetic properties favorable for permanent magnet applications.
Low-complexity Recurrent Neural Network-based Polar Decoder with Weight Quantization Mechanism (2018)

Polar codes have drawn much attention and been adopted in 5G New Radio (NR) due to their capacity-achieving performance. Recently, as the emerging deep learning (DL) technique has breakthrough achievements in many fields, neural network decoder was proposed to obtain faster convergence and better performance than belief propagation (BP) decoding. However, neural networks are memory-intensive and hinder the deployment of DL in communication systems. In this work, a low-complexity recurrent neural network (RNN) polar decoder with codebook-based weight quantization is proposed. Our test results show that we can effectively reduce the memory overhead by 98% and alleviate computational complexity with slight performance loss.
Activity Intensity During Free-Living Activities in Children and Adolescents With Inherited Arrhythmia Syndromes (2013)

Tumor Galectin-1 Mediates Tumor Growth and Metastasis through Regulation of T-Cell Apoptosis (2011)

Galectin-1 (Gal-1), a carbohydrate-binding protein whose secretion is enhanced by hypoxia, promotes tumor aggressiveness by promoting angiogenesis and T-cell apoptosis. However, the importance of tumor versus host Gal-1 in tumor progression is undefined. Here we offer evidence that implicates tumor Gal-1 and its modulation of T-cell immunity in progression. Comparing Gal-1-deficient mice as hosts for Lewis lung carcinoma cells where Gal-1 levels were preserved or knocked down, we found that tumor Gal-1 was more critical than host Gal-1 in promoting tumor growth and spontaneous metastasis. Enhanced growth and metastasis associated with Gal-1 related to its immunomodulatory function, insofar as the benefits of Gal-1 expression to Lewis lung carcinoma growth were abolished in immunodeficient mice. In contrast, angiogenesis, as assessed by microvessel density count, was similar between tumors with divergent Gal-1 levels when examined at a comparable size. Our findings establish that tumor rather than host Gal-1 is responsible for mediating tumor progression through intratumoral immunomodulation, with broad implications in developing novel targeting strategies for Gal-1 in cancer.
First Asymmetric Total Synthesis of Synerazol, an Antifungal Antibiotic, and Determination of Its Absolute Stereochemistry (2005)

[reaction: see text] By synthesizing two possible diastereomers, the first asymmetric total synthesis of synerazol, an antifungal antibiotic, has been accomplished, allowing determination of its absolute stereochemistry. A more practical second generation route was also established. The key steps are racemization-free deprotection of a TIPS group and introduction of a methyl ether by DMD oxidation of the benzylidene moiety in a substrate having a small protecting group.
In Situ Phage Screening (2002)

We have established a novel method, in situ phage screening (ISPS), to identify proteins in tissue microstructures. The method is based on the selection of repertoires of phage-displayed antibody fragments with small samples of tissues microdissected using a laser. Using a human muscle frozen section with an area of 4800 microm2 as a model target, we successfully selected monoclonal antibody fragments directed against three major (myosin heavy chain, actin, and tropomyosin-alpha) and one minor (alpha-actinin 2) muscle constituent proteins. These proteins were present in the sample in amounts less than one nanogram, and the antibodies were used to visualize the proteins in situ. This shows that the use of ISPS can obtain monoclonal antibodies for histochemical and biochemical purposes against minute amounts of proteins from microstructures with no requirement for large amounts of samples or biochemical efforts.
