Fast design optimization of UWB antenna with WLAN band-notch (2015)

In this paper, a methodology for rapid design optimization of an ultra-wideband (UWB) monopole antenna with a lower WLAN band-notch is presented. The band-notch is realized using an open loop resonator implemented in the radiation patch of the antenna. Design optimization is a two stage process, with the first stage focused on the design of the antenna itself, and the second stage aiming at identification of the appropriate dimensions of the resonator with the purpose of allocating the band-notch in the desired frequency range. Both optimization stages are realized using surrogate-based optimization involving variable-fidelity electromagnetic (EM) simulation models as well as an additive response correction (first stage), and sequential approximate optimization (second stage). The final antenna design is obtained at the CPU cost corresponding to only 23 high-fidelity EM antenna simulations.
Molecular characterization of deletion at 11q22.1‐23.3 in mantle cell lymphoma (1999)

Chromosomal deletions at 11q21-23 have recently been reported to be common aberrations in mantle cell lymphoma (MCL). To characterize the structure of the deletion, we studied 41 cases of MCL by fluorescence in situ hybridization using a YAC contig, which spans the region at 11q22.1-23.3. 17 MCLs were studied using a set of 20 yeast artificial chromosomes (YACs) in a contig, and nine of these cases showed deletion of 11q22-23. The deletion spanned several megabases in all but one case, where only YAC 755b11 at 11q23.1, covering approximately a 1.6 Mb of DNA, was deleted. Analysis of additional 24 MCLs with YAC 755b11 revealed the deletion in 49% of all cases (20/41). The deleted region at 11q22.1-23.3 was discontinuous in five lymphomas and in the majority of the cases the distal breakpoint occurred between YACs 785e12 and 911f2 at 11q23.3. We conclude that the deletion of 11q22-23 and particularly the deletion of YAC 755b11 are very common in MCL and may be important in the genesis or progression of the disease.

Positive End-Expiratory Pressure Modulates Perfluorochemical Evaporation from the Lungs (2003)

To study the effects of positive end-expiratory pressure (PEEP) level on perfluorochemical (PFC) elimination profiles (E(L)), 6 ml/kg of perflubron were instilled into healthy anesthetized rabbits. The ventilation strategy was to maintain constant minute ventilation (300 ml/kg/min) and mean airway pressure (7-8 cm H(2)O) while randomly changing the PEEP levels from 5 to 0, 1, 3, and 10 cm H(2)O, each for a period of 15 min. The PFC content in the expired gas was measured and the E(L) was calculated. There was a significant reduction in the E(L) when decreasing the PEEP levels from 5 to 0 cm H(2)O, but no differences were seen when the PEEP was increased from 5 to 10 cm H(2)O. The results indicate that PEEP levels influence PFC elimination profiles; therefore, the measurement of the E(L) and PEEP levels should be considered when optimizing supplemental PFCs during partial liquid ventilation.
Joint Industry Academia Collaborative Efforts in Workforce Development for the Power Industry (2019)

This paper summarizes workforce development efforts that are underway in the Carolinas with the help of a regional industry-led consortium, namely, “The Center for Advanced Power Engineering Research (CAPER).” The three CAPER university members, Clemson University, NC State University, and UNC Charlotte, have met on a number of occasions to discuss the different aspects of workforce development efforts. We describe the entire process, from core competencies needed to how and where the training should be done. For individuals aspiring to work in the power industry, in addition to possessing a strong knowledge in the fundamentals of power engineering, there are several other attributes that the industry looks for in a potential candidate. While industry is mostly clear on what attributes they look for in their new employee candidates, the challenge for universities is to build the right curriculum, offer opportunities to develop the soft skills, provide interaction with industry and build a spirit of collaboration among students in order to prepare them for future careers in power engineering. This paper also discusses a variety of university perspectives and experience with developing the curriculum and the different ways to involve all industry stakeholders in the educational process.
Potent Bactericidal Antimycobacterials Targeting the Chaperone ClpC1 Based on the Depsipeptide Natural Products Ecumicin and Ohmyungsamycin A (2022)

Ohmyungsamycin A and ecumicin are structurally related cyclic depsipeptide natural products that possess activity against <i>Mycobacterium tuberculosis</i> (Mtb), the causative agent of tuberculosis (TB). Herein, we describe the design and synthesis of a library of analogues of these two natural products using an efficient solid-phase synthesis and late-stage macrolactamization strategy. Lead analogues possessed potent activity against Mtb in vitro (minimum inhibitory concentration 125-500 nM) and were shown to inhibit protein degradation by the mycobacterial ClpC1-ClpP1P2 protease with an associated enhancement of ClpC1 ATPase activity. The most promising analogue from the series exhibited rapid bactericidal killing activity against Mtb, capable of sterilizing cultures after 7 days, and retained bactericidal activity against hypoxic non-replicating Mtb. This natural product analogue was also active in an in vivo zebrafish model of infection.

A new compensation technique for two-stage CMOS operational transconductance amplifiers (2004)

This paper presents a new compensation method for fully differential two-stage CMOS operational transconductance amplifiers (OTAs). It employs a hybrid cascode compensation scheme, merged Ahuja and improved Ahuja style compensations, for fast settling. A design procedure for minimum settling time of the proposed compensation technique for a two-stage class A/AB OTA is described. To demonstrate the usefulness of it, three design examples are considered.
Webrb (2007)

Many web-applications can be characterized as "relational". In this paper we introduce and evaluate WebRB , a visualdomain-specific language for building such applications. WebRB addresses the limitations of the conventional "imperative-embedding" approach typically used to build relational web-applications. We describe the WebRB language, present extended examples of its use, and discuss the WebRB visual editor, libraries, and runtime. We then evaluate WebRB by comparing it to alternative approaches, and demonstrate its effectiveness in building relational web-applications.
Using observation and refinement to improve distributed systems test (2003)

Testing a distributed system is difficult. Good testing depends on both skill and understanding the system under test. We have developed a method to observe the system at the CORBA remote-procedure-call level and then use dynamic-query-based visualization to refine and improve the test cases. The method and accompanying tools have been tested and refined by using them as part of the software support effort for two distributed application, each having about 500 K lines of code. During this time the tools have been adapted to support testing by adding a scripting mechanism that permits the visualization tool to specify test reports. We also added parameter value observation and reporting. Finally, we added an active probing mechanism to induce faults and delays in order to stress the system under test. Our efforts have led to a substantial improvement in system test quality.
A Nonlinear Acoustic Technique for Crack Detection in Metallic Structures (2009)

A crack detection technique based on nonlinear acoustics is investigated in this study. Acoustic waves at a chosen frequency are generated using an actuating lead zirconate titanate (PZT) transducer, and they travel through the target structure before being received by a sensing PZT wafer. Unlike an undamaged medium, a cracked medium exhibits high acoustic nonlinearity which is manifested as harmonics in the power spectrum of the received signal. Experimental results also indicate that the harmonic components increase nonlinearly in magnitude with increasing amplitude of the input signal. The proposed technique identifies the presence of cracks by looking at the two aforementioned features: harmonics and their nonlinear relationship to the input amplitude. The effectiveness of the technique has been tested on aluminum and steel specimens. The behavior of these nonlinear features as crack propagates in the steel beam has also been studied.
Determinants of Ganglion Cell–Inner Plexiform Layer Thickness Measured by High-Definition Optical Coherence Tomography (2012)

Thinner GC-IPL was independently associated with older age, female sex, longer axial length, and thinner RNFL thickness. These factors should be taken into account when interpreting GC-IPL thickness measurements with HD-OCT for glaucoma assessment.
Interference dips in molecular absorption spectra calculated for coupled electronic state potential surfaces (1992)

Interference effects in electronic absorption spectra caused by coupling between excited states are calculated and interpreted by using numerical integration of the time-dependent Schrödinger equation and the time-dependent theory of electronic spectroscopy. The interference between nearby spin-forbidden doublet and spin-allowed quartet states of chromium (III) and vanadium (II) metal complexes causes sharp decreases of intensity or dips in the envelopes of absorption bands. The states are coupled by spin–orbit coupling. The origin of the dips is explained in terms of interference between wave packets moving on potential energy surfaces representing the states. The importance of curve crossing and amplitude transfer between the states is analyzed quantitatively. The theory is applied to the absorption spectrum of a chromium (III) complex.
The amino acid sequence specificity of a protease from spores of Bacillus megaterium. (1980)

Previous work has shown that the degradation of 20% of total protein which occurs early in germination of Bacillus megaterium spores is initiated by an endoprotease. This enzyme is found only in the spore and is active only on the spore proteins degraded during germination. Action of the spore protease in vitro on the three major proteins (Proteins A, B, and C) which are degraded in vivo during germination results in cleavage of one (A and C protein) or two (B protein) peptide bonds. The sequences surrounding the cleavage sites are -Tyr-Glu- Ile-Ala-Ser-Glu-Phe- in the A protein, -Phe-Glu- Ile-Ala-Ser-Glu-Phe- in the C protein, and -Thr-Glu- Phe-Gly-Ser-Glu-Thr-, and -Thr-Glu- Phe-Ala-Ser-Glu-Thr- in the B protein, with cleavage taking place at the glutamyl bond noted by the arrow. The similarity of these four sequences suggests the possibility that the specificity of the spore protease may be due to its requirement for a specific pentapeptide sequence of the type -R-Glu-(Phe or Ile)-(Gly or Ala)-Ser-Glu-R- for recognition and cleavage. However, it is also possible that it is the conformation of the A, B, and C proteins which determines their site of cleavage by the spore protease.
A Tumor Progression Model for Hepatocellular Carcinoma: Bioinformatic Analysis of Genomic Data (2006)

A tumor progression model for HCC was constructed and revealed chromosomal imbalances that were significantly associated with clinical pathologic characteristics of the disease. This model explains a significant part of the variations in clinical outcome among HCC patients.
Intensities of Calcium Dipicolinate and Bacillus Subtilis Spore Raman Spectra Excited with 244 nm Light (2004)

Ultraviolet (UV) resonance Raman spectra of Bacillus subtilis endospores have been excited at 244 nm. Spectra can be interpreted in terms of contributions from calcium dipicolinate and nucleic acid components. Differences between spectra of spores and vegetative cells are very large and are due to the dominance of the dipicolinate features in the spore spectra. Because the DNA and RNA composition of B. subtilis spores is known and because the cross-sections of Raman bands belonging to DNA and RNA bases are known, it is possible to calculate resonance Raman spectral cross-sections for the spore Raman peaks associated with the nucleic acids. The cross-sections of peaks associated with calcium dipicolinate have been measured from aqueous solutions. Cross-section values of the dominant 1017 cm(-1) calcium dipicolinate peak measured from the Bacillus spores have been shown to be consistent with a calcium dipicolinate composition of ten percent or less by weight in the spores. It is suggested that spectral cross-sections of endospores excited at 244 nm can be estimated to be the sum of the cross-sections of the calcium dipicolinate, DNA, and RNA components of the spore. It appears that the peaks due to DNA and RNA can be used as an internal standard in the calculation of spore Raman peak cross-sections, and potentially the amount of calcium dipicolinate in spores. It is estimated on the basis of known nucleic acid base cross-sections that the most intense Raman band of the Bacillus subtilis spore spectra has a cross-section of no more than 4 x 10(-18) cm(2)/mol-sr.
The Vaginal Acquisition and Dissemination of HIV-1 Infection in a Novel Transgenic Mouse Model Is Facilitated by Coinfection with Herpes Simplex Virus 2 and Is Inhibited by Microbicide Treatment (2015)

Multiple epidemiological studies have reported that genital herpes simplex virus 2 (HSV-2) infection increases the risk of HIV-1 sexual acquisition by severalfold. Understanding the underlying mechanisms by which HSV-2 facilitates HIV-1 infection and optimizing the efficacy of therapies to inhibit HIV-1 infection during HSV-2 coinfection should contribute to reducing HIV-1 transmission. Using our novel transgenic hCD4/R5/cT1 mouse model infectible with HIV-1, we demonstrated that HSV-2 infection enhances vaginal transmission and dissemination of HIV-1 infection while stimulating recruitment and activation of CD4(+) T cells and dendritic cells in the lower genital tract. HIV acquisition by hCD4/R5/cT1 mice vaginally coinfected with HSV-2 could be completely prevented in almost half the mice by preexposure prophylaxis (PrEP) with a novel gel containing tenofovir disoproxil fumarate (TDF), the tenofovir prodrug, but not with the tenofovir microbicide gel utilized in CAPRISA-004, VOICE, and FACTS-001 clinical trials. The hCD4/R5/cT1 mice represent a new preclinical mouse model to evaluate vaginal HIV-1 acquisition.
Level-Crossing Studies of Na2 Using Laser-Induced Fluorescence (1969)

The technique of using laser excitation to study level crossings in molecules has been developed and used to determine the radiative lifetime of an excited state of Na2. Optical detection of level crossing in the υ′ = 10, J′ = 12 level of the B 1Πu electronic state of Na2, excited by the 4765-Å argon-ion laser line, has resulted in a precise measurement of the product gτ = 4.11 ± 0.12 × 10−11sec, corresponding to a magnetic field half-width of 1385 ± 42 G. If the g value is calculated assuming Hund's coupling case (a), the radiative lifetime is determined to be τ = 6.41 ± 0.38 × 10−9sec. The influence of molecular hyperfine structure on this measurement is discussed and is found in general to contribute little uncertainty to the value of the radiative lifetime, provided the rotational angular momentum is much larger than the nuclear spin and/or provided the hyperfine interaction is much smaller than the natural width of the excited state.
Mechanical Properties of High Nitrogen - High Strength Stainless Steels in High Pressure Gaseous Hydrogen Environment (2013)

The susceptibility to hydrogen embrittlement and the fatigue properties of several high nitrogen stainless steels were evaluated by SSRT (Slow Strain Rate Test) and external fatigue test. The tensile properties were evaluated by SSRT in gaseous hydrogen pressurized up to 90MPa in the temperature range from −40 degree C to room temperature. Despite the increase of nitrogen content, high nitrogen stainless steels showed no degradation by hydrogen. The susceptibility to hydrogen embrittlement depended on the chemical compositions. Fatigue properties in high pressure gaseous hydrogen were evaluated by the external cyclic pressurization test using tubular specimens. In this test the tubular specimen was filled with high pressure hydrogen gas filled with hydrogen pressurized up to 90MPa, and the outside of the specimen was cyclically pressurized with water pressurized up to 90MPa. The difference of fatigue life between hydrogen and inert gas was extremely small. Susceptibility to hydrogen embrittlement was discussed based on stability of an austenitic structure.

The Access Control Model in Ubiquitous Sensor Network Environment (2009)

With the increasing need for intelligent environment monitoring applications and the decreasing cost of manufacturing sensor devices, it is likely that a wide variety of sensor networks will be deployed in the near future. In this environment, the way to access heterogeneous sensor networks and the way to integrate various sensor data are very important. The COSMOS is a kind of USN middleware that plays a central service platform part in USN service environment. The COSMOS provides its own services (sensor network abstraction query processing, etc) using multiple heterogeneous sensor networks to the various USN applications. Multiple applications share USN middleware services with other USN applications. Therefore, access control to COSMOS is very important for the applications which shares USN middleware services. This paper introduces the access control model which is implemented in COSMOS to control multiple applications' access to COSMOS.
Germanium ion implantation to Improve Crystallinity during Solid Phase Epitaxy and the effect of AMU Contamination (2006)

Germanium ion implantation was investigated for crystallinity enhancement during solid phase epitaxial regrowth (SPE) using high current implantation equipment. Electron back‐scatter diffraction(EBSD) measurement showed numerical increase of 19 percent of 〈100〉 signal, which might be due to pre‐amorphization effect on silicon layer deposited by LPCVD process with germanium ion implantation. On the other hand, electrical property such as off‐leakage current of NMOS transistor degraded in specific regions of wafers, which implied non‐uniform distribution of donor‐type impurities into channel area. It was confirmed that arsenic atoms were incorporated into silicon layer during germanium ion implantation. Since the equipment for germanium pre‐amorphization implantation(PAI) was using several source gases such as BF3 and AsH3, atomic mass unit(AMU) contamination during PAI of germanium with AMU 74 caused the incorporation of arsenic with AMU 75 which resided in arc‐chamber and other parts of the equipment. It was effective to use germanium isotope of AMU 72 to suppress AMU contamination, however it led serious reduction of productivity because of decrease in beam current by 30 percent as known to be difference in isotope abundance. It was effective to use enriched germanium source gas with AMU 72 in order to improve productivity. Spatial distribution of arsenic impurities in wafers was closely related to hardware configuration of ion implantation equipment.
Propylene Polymerization Using 4th Generation Ziegler-Natta Catalysts: Polymerization Kinetics and Polymer Microstructural Investigation (2011)

A systematic study of propylene polymerization using a 4th generation Ziegler-Natta catalyst is presented in this thesis. The apparent kinetic rate constants for propylene polymerization were estimated in the presence and absence of hydrogen and/or donor. The estimated activation energies for activation, propagation, and deactivation were found to be close to values previously reported in the literature for similar catalysts. The polypropylene samples were characterized using high-temperature gel permeation chromatography (GPC), carbon-13 nuclear magnetic resonance (13C NMR), and crystallization elution fractionation (CEF). The effect of hydrogen and external electron donor on polypropylene microstructure was investigated at two polymerization temperatures. In addition to the expected electron donor positive effect on tacticity, hydrogen was also found to increase polypropylene tacticity. The effect of changing these polymerization conditions on molecular weight and polydispersity was also investigated. Finally, CEF profiles show how the distribution of polypropylene crystallizability changes by adding hydrogen and electron donor to the reactor. The concentrations of hydrogen and external donor were also varied to study their effect of polymerization kinetics and polymer microstructure. The estimated activation energies were close to those found in the first part of this investigation in the presence and/or absence of donor and hydrogen. A polypropylene microstructural study showed a positive effect of hydrogen concentration on mmmm pentad at low donor concentration, likely due to an increase in stereoselectivity of the aspecific sites by hydrogen. However, increasing donor concentration over a given threshold seems to transform the aspecific sitess into stereospecific sites that are no longer significantly affected by hydrogen. These experimental results were compared to a previously developed Monte Carlo model and found to agree with the trends predicted by simulation. Finally, the effect of diisopropyldimethoxysilane (P), n-propyltrimethoxysilane (N), paraethoxyethylbenzoate (PEEB), and dicyclopentyldimethoxysilane (D) external donors on catalyst activity and stereoselectivity was investigated. P and D donors were more stereoselective than N and PEEB donors; however, D donor had the best activity among all donors investigated. Therefore, D donor was mixed with PEEB to combine its high activity with the self-extinguishing properties of PEEB. The D/PEEB 90/10 (mol/mol) mixture generated a catalyst with good stereoselectivity but poor activity. When the ratio was increased to 95/5 and 98/2, the resulting catalyst had high activity and good stereoselectivity. Interestingly, the D/PEEB combination with just a small fraction of PEEB has a positive effect on the catalysts activation term which may decrease polymerization costs with this system.
