Defective IL-5-receptor-mediated signaling in B cells of X-linked immunodeficient mice (1995)

Murine (m) IL-5 induces proliferation and differentiation of both Ly-1+ B cells and activated conventional B cells. X-linked immunodeficient (XID) mice do not respond to thymus-independent type II antigens, and have an abnormal response to a variety of activation signals through Ig receptors, CD40 and cytokine receptors. Furthermore, XID mice show a B cell specific defect, reflected in decreased numbers of IL-5R alpha+ B cells and reduced responsiveness of IL-5R alpha+ B cells to mIL-5. We generated IL-5R alpha transgenic (5R alpha-Tg) mice in which B cells expressed recombinant IL-5R alpha. We crossed male 5R alpha-Tg mice with female XID mice and used their offspring to determine the IL-5 responsiveness of these B cells. All B cells of F1 male mice carrying the xid gene together with the transgene expressed the recombinant IL-5R alpha. However, those mice lacked Ly-1 B cells and their B cells acquired responsiveness to mIL-5. Interestingly, XID-5R alpha-Tg B cells, but not XID B cells, acquired mIL-5 proliferative and Ig-secretory responsiveness only in the presence of suboptimal doses of lipopolysaccharide. Stimulation of these B cells with mIL-5 plus phorbol myristate acetate induced proliferation, but not Ig secretion. These results indicate that the impaired mIL-5 responsiveness of B cells in XID mice is due to an abnormality of IL-5R-mediated signaling which may correlate with the xid gene mutation, alteration of a single amino acid of Bruton's tyrosine kinase.

Role of sugar chains in the in‐vitro activity of recombinant human interleukin 5 (1993)

The structures of O-linked sugar chains of recombinant human interleukin 5 (rhIL-5) produced by Chinese hamster ovary cells were determined employing high-performance anion-exchange column chromatography under high pH conditions. The core sequence was elucidated to be Gal beta 1-->3-GalNAc by its susceptibility to endo-alpha-N-acetylgalactosaminidase and sialic acid linkages were determined using sialidases of different specificities. To investigate the role of sugar chains in the in-vitro activity of rhIL-5, it was digested with various glycosidases. While removal of N-linked sugar chains resulted in 2.8-fold increase of the activity, de-O-glycosylated rhIL-5 showed 10-fold higher activity than intact rhIL-5, suggesting that the presence of O-linked sugar chains suppresses the activity more effectively than that of N-linked chains. While incubation of de-N-glycosylated rhIL-5 at 70 degrees C for 30 min decreased the activity, intact and de-O-glycosylated rhIL-5 lost little activity, suggesting that N-linked sugar chains contributed to the thermostability of the molecule.
Influence of Formic Acid Impurity on Proton Exchange Membrane Fuel Cell Performance (2009)

The effect of trace amounts of formic acid (HCOOH) on proton exchange membrane fuel cell (PEMFC) performance is reported. Experimental approaches including long term stability test, cyclic voltammetry (CV) scans and electrochemical impedance spectroscopy (EIS) were used to evaluate and characterize the contamination. The results show that trace amounts of HCOOH can cause degradation in fuel cell performance and significantly contaminate the electrodes. Furthermore, fully recovery from the contamination could not be achieved only by reverting to pure hydrogen while operating the fuel cell. Mechanisms of contamination of the electrodes and performance degradation of the PEMFC are also postulated.

Clustering Aggregation (2005)

We consider the following problem: given a set of clusterings, find a clustering that agrees as much as possible with the given clusterings. This problem, clustering aggregation, appears naturally in various contexts. For example, clustering categorical data is an instance of the problem: each categorical variable can be viewed as a clustering of the input rows. Moreover, clustering aggregation can be used as a meta-clustering method to improve the robustness of clusterings. The problem formulation does not require a-priori information about the number of clusters, and it gives a natural way for handling missing values. We give a formal statement of the clustering-aggregation problem, we discuss related work, and we suggest a number of algorithms. For several of the methods we provide theoretical guarantees on the quality of the solutions. We also show how sampling can be used to scale the algorithms for large data sets. We give an extensive empirical evaluation demonstrating the usefulness of the problem and of the solutions.
Compressed Sensing with Applications in Wireless Networks (2019)

Sparsity is an attribute present in a myriad of natural signals and systems, occurring either inherently or after a suitable projection. Such signals with lots of zeros possess minimal degrees of freedom and are thus attractive from an implementation perspective in wireless networks. While sparsity has appeared for decades in various mathematical fields, the emergence of compressed sensing (CS) – the joint sampling and compression paradigm – in 2006 gave rise to plethora of novel communication designs that can efficiently exploit sparsity. In this monograph, we review several CS frameworks where sparsity is exploited to improve the quality of signal reconstruction/detection while reducing the use of radio and energy resources by decreasing, e.g., the sampling rate, transmission rate, and number of computations. The first part focuses on several advanced CS signal reconstruction techniques along with wireless applications. The second part deals with efficient data gathering and lossy compression techniques in wireless sensor networks. Finally, the third part addresses CS-driven designs for spectrum sensing and multi-user detection for cognitive and wireless communications.
Energy-Harvesting Active Networked Tags (EnHANTs) (2015)

This article focuses on a new type of wireless devices in the domain between RFIDs and sensor networks—Energy-Harvesting Active Networked Tags (EnHANTs). Future EnHANTs will be small, flexible, and self-powered devices that can be attached to objects that are traditionally not networked (e.g., books, furniture, toys, produce, and clothing). Therefore, they will provide the infrastructure for various tracking applications and can serve as one of the enablers for the Internet of Things. We present the design considerations for the EnHANT prototypes, developed over the past 4 years. The prototypes harvest indoor light energy using custom organic solar cells, communicate and form multihop networks using ultra-low-power Ultra-Wideband Impulse Radio (UWB-IR) transceivers, and dynamically adapt their communications and networking patterns to the energy harvesting and battery states. We describe a small-scale testbed that uniquely allows evaluating different algorithms with trace-based light energy inputs. Then, we experimentally evaluate the performance of different energy-harvesting adaptive policies with organic solar cells and UWB-IR transceivers. Finally, we discuss the lessons learned during the prototype and testbed design process.

A high-performance JPEG2000 architecture (2003)

JPEG2000 is an upcoming compression standard for still images that has a feature set well tuned for diverse data dissemination. These features are possible due to adaptation of the discrete wavelet transform, intra-subband bit-plane coding, and binary arithmetic coding in the standard. We propose a system-level architecture capable of encoding and decoding the JPEG2000 core algorithm that has been defined in Part I of the standard. The key components include dedicated architectures for wavelet, bit plane, and arithmetic coders and memory interfacing between the coders. The system architecture has been implemented in VHDL and its performance evaluated for a set of images. The estimated area of the architecture, in 0.18-/spl mu/ technology, is 3-mm square and the estimated frequency of operation is 200 MHz.
Evaluation of novel protease enzymes on growth performance and nutrient digestibility of poultry: enzyme dose response (2019)

Two experiments were conducted to evaluate 3 novel proteases in broilers. In experiment 1, 600 male, Cobb 500 broilers were allocated to 1 of 12 experimental diets (5 birds/pen and 10 replicates/diet). A control (C) diet was formulated to be adequate in all nutrients. Proteases 1, 2, or 3 were added to this diet at 3 doses (1x, 3x, or 9x) in a 3 × 3 factorial arrangement of treatments. The factorial was augmented with 2 treatments of phytase at 500 or 1,500 FTU/kg added to the C diet. In experiment 2, 2,050 male Ross 308 broilers were allocated to 1 of 10 experimental diets (25 birds/pen and 9 replicates/diet). A C diet was formulated to be adequate in all nutrients. Protease 1, 2, or 3 was then added to the C diet at 3 doses (1x, 2x, or 4x) in a 3 × 3 factorial arrangement of treatments plus the C. In experiment 1, birds fed phytase gained more (P < 0.05) than birds fed protease, but neither were different than birds fed the C. Supplementation of 9x dose of any protease resulted in a reduction (P < 0.05) in BWG when compared with birds fed 1x dose of protease or phytase at 500 or 1,500 FTU/kg. Feed conversion ratio was improved (P < 0.05) in birds fed phytase compared with birds fed the C diet. Nitrogen digestibility was greater (P < 0.05) in birds fed protease 1 when compared with birds fed protease 2. Birds fed the 1x dose of protease or 500 FTU/kg of phytase had a greater (P < 0.05) N digestibility than birds fed 3x dose of protease. In experiment 2, protease supplementation significantly reduced (P < 0.05) BWG when compared with birds fed the C from hatch to 35 D post-hatch. Protease supplementation did not improve broiler growth performance or N digestibility above that of a nutrient adequate control diet or a diet supplemented with 500 FTU/kg of phytase.

Structure of Polymer Tethered Highly Grafted Nanoparticles (2011)

Spherical nanoparticles of silica grafted with a dense brush of low-polydispersity polymers prepared by living radical polymerization are shown to form ordered crystalline structures. The minimum distance between nanoparticle surfaces, a good measure of the end-to-end distance of the tethered polymers, scales as the square root of the molecular weight of the polymer chains. The blending of the grafted nanoparticles with homopolymers of matched and mismatched molecular weights indicates that the crystalline order persists even with high amounts of homopolymer added and for such diluted systems with as little as 0.7 vol % silica.
Frequency response compensation with dsp (2003)

In modern telecommunication systems, there are situations when test instruments must work over hundreds of narrowband-frequency channels. It is difficult and expensive, however, to build hardware test equipment with a flat frequency response over their full operational frequency range. In this situation simple finite impulse response (FIR) filters can be applied for gain compensation to improve an instrument's frequency response flatness. This column describes a very fast method for run time design of these filters, while minimizing storage requirements, based on test instrument calibration data.

Perfect focusing of scalar wave fields in three dimensions (2010)

A method to design isotropic inhomogeneous refractive index distribution is presented, in which the scalar wave field solutions propagate exactly on an eikonal function (i.e., remaining constant on the Geometrical Optics wavefronts). This method is applied to the design of "dipole lenses", which perfectly focus a scalar wave field emitted from a point source onto a point absorber, in both two and three dimensions. Also, the Maxwell fish-eye lens in two and three dimensions is analysed.
NanoScience Concentration Program for science, engineering and technology curricula (2012)

This paper reports the developments of a NanoScience Concentration Program at University of Texas at Brownsville. The long-term goal is to introduce nanoscience, nanoengineering and nanotechnology through interdisciplinary approaches into undergraduate education. The rationale for the proposed multidisciplinary NanoScience Program is to integrate and expand nanotechnology-relevant courses within a comprehensive curriculum. This program is expected to reach out to a large group of undergraduate students in a coordinated manner, enable students knowledge and skills, as well as facilitate efforts of individual faculty members. We discuss the integration of quantum physics, electronics, microsystems and nanotechnology in science, engineering and technology curricula. The proposed NanoScience Program includes a number of undergraduate courses which currently under developments, offering, assessment and evaluation. Coherent, cohesive and consistent courses coverage spans from the first principles and basic fundamentals to design, analysis, fabrication, testing, characterization and evaluation of nanodevices and nanosystems.
Wireless communication for hearing aid system (2012)

This thesis focuses on the wireless coupling between hearing aids close to a human head. Hearing aids constitute devices withadvanced technology and the wireless communication enables the introduction of a range of completely new functionalities. Such devices are small and the available power is limited, it is therefore important to characterize the wireless link-budget and tounderstand the mechanisms that control propagation of waves inside and outside the head. For this purpose, different approaches have been used. There are two objectives for this thesis. The first objective is to characterize the ear-to-ear wireless communication channel by understanding the mechanisms that control the propagations of the signals and the losses. The second objective isto investigate the properties of magneto-dielectric materials and their potential in antenna miniaturization. There are three approaches to study the ear-to-ear wireless communication link; a theoretical approach models the human head asa sphere that has the electrical properties of the head, a numerical approach implements a more realistic geometry of the head, and an experimental approach measures directly the coupling between the antennas near a real persons or a phantom head imitating the human head’s electrical properties. Each approach has advantages and disadvantages; the analytical approach gives accurate results and is very fast, though it does not treat complex structures. The numerical approach can treat complex structures but is limited by the electrical size of the structures and requires large memory and long processingtime. The experimental approach yields accurate coupling between the antennas but does not provides detailed information about the field distribution. Therefore, we combine all these three approaches to gain some understanding of the ear-to-ear wireless communication channel. A circular patch antenna was used to study the properties of the magneto-dielectric materials. In the thesis, we focused on three properties; efficiency, quality factor and bandwidth of the antenna. An analytical method is used to calculatethe properties of a low-loss circular patch antenna, while a numerical method was used to analyze a highloss circular patch antenna. The low-loss magneto-dielectric materials can potentially be used to miniaturize the size of the antennas, offering higher efficiency and wider bandwidth than the dielectric materials.

Determination of 4‐methylpiperaine‐1‐carbodithioc acid 3‐cyano‐3,3‐diphenylpropyl ester hydrochloride in rats’ plasma by online‐SPE‐HPLC‐DAD: Application to a pharmacokinetic study (2012)

A specific, simple, and fast online-solid-phase extraction-high performance liquid chromatography-diode array detector (SPE-HPLC-DAD) method was developed and validated to quantify 4-methylpiperaine-1-carbodithioc acid 3-cyano-3,3-diphenylpropyl ester hydrochloride (TM208) in small volume samples of rats' plasma for the first time. In this method, the 50-μL plasma sample was taken to perform protein precipitation with 75 μL methanol, and then 50 μL supernatant containing the target analytes was injected and concentrated automatically in a C18 solid-phase extraction (SPE) cartridge. After that the sample was separated on a C18 RP analytical column and analyzed by DAD. The run cycle time is 6.0 min for each sample, and the calibration curve over the range of 0.03 to 25.00 μg/mL has a good linear relationship (r > 0.9998). The recoveries of the quality control samples were all greater than 90%. The limit of detection and the lowest limit of quantification were 0.01 and 0.03 μg/mL, respectively. Finally, this method was successfully applied to a pharmacokinetic study of TM208 in rats.
Properties of Ultra Low Density Polyethylenes (1994)

With the new metallocene catalyst technology, ethylene copoly mers of unprecedented lower densities are being introduced rapidly. Since these very low density polyolefins offer interesting mechanical properties, a systematic investigation into their thermal and mechanical properties was made. It was found, for example, that despite the low densities achieved, wide compositional variations existed between materials. A comparison was also made between the thermal mechanical properties with optical properties, with the conclusion that compositional homogeneities are required for good optical properties.

Coordinating government funding of file system and I/O research through the high end computing university research activity (2009)

In 2003, the High End Computing Revitalization Task Force designated file systems and I/O as an area in need of national focus. The purpose of the High End Computing Interagency Working Group (HECIWG) is to coordinate government spending on File Systems and I/O (FSIO) R&amp;D by all the government agencies that are involved in High End Computing. The HECIWG tasked a smaller advisory group to list, categorize, and prioritize HEC I/O and File Systems R&amp;D needs. In 2005, leaders in FSIO from academia, industry and government agencies collaborated to list and prioritize areas of research in HEC FSIO. This led to a very successful High End Computing University Research Activity (HECURA) call from NSF in 2006 and has prompted a new HECURA call from NSF in 2009. This paper serves as both a review of the 2008 HEC FSIO identified research gaps as well as a preview of this forthcoming HECURA call.
Sum Rate Analysis of a Reduced Feedback OFDMA Downlink System Employing Joint Scheduling and Diversity (2011)

We consider joint scheduling and diversity to enhance the benefits of multiuser diversity in an orthogonal frequency-division multiple access (OFDMA) downlink system. The OFDMA spectrum is assumed to consist of N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RB</sub> resource blocks and the reduced feedback scheme consists of each user feeding back channel quality information (CQI) for only the best-N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FB</sub> resource blocks. Assuming largest normalized CQI scheduling and a general value for N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FB</sub> , we develop a unified framework to analyze the sum rate of the system for both the quantized and nonquantized CQI feed- back schemes. Based on this framework, we provide closed-form expressions for the sum rate for three different multiantenna transmitter schemes; transmit antenna selection (TAS), orthogonal space time block codes (OSTBC) and cyclic delay diversity (CDD). Furthermore, we approximate the sum rate expression and determine the feedback ratio (N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FB</sub> /N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RB</sub> ) required to achieve a sum rate comparable to the sum rate obtained by a full feedback scheme.
