Timing, Carrier, and Frame Synchronization of Burst-Mode CPM (2013)

In this paper, we propose a complete synchronization algorithm for continuous phase modulation (CPM) signals in burst-mode transmission over additive white Gaussian noise (AWGN) channels. The timing and carrier recovery are performed through a data-aided (DA) maximum likelihood algorithm, which jointly estimates symbol timing, carrier phase, and frequency offsets based on an optimized synchronization preamble. Our algorithm estimates the frequency offset via a one-dimensional grid search, after which symbol timing and carrier phase are computed via simple closed-form expressions. The mean-square error (MSE) of the algorithm's estimates reveals that it performs very close to the theoretical Cramer-Rao bound (CRB) for various CPMs at signal-to-noise ratios (SNRs) as low as 0 dB. Furthermore, we present a frame synchronization algorithm that detects the arrival of bursts and estimates the start-of-signal. We simulate the performance of the frame synchronization algorithm along with the timing and carrier recovery algorithm. The bit error rate results demonstrate near ideal synchronization performance for low SNRs and short preambles.
Protein Information Resource: a community resource for expert annotation of protein data (2001)

The Protein Information Resource, in collaboration with the Munich Information Center for Protein Sequences (MIPS) and the Japan International Protein Information Database (JIPID), produces the most comprehensive and expertly annotated protein sequence database in the public domain, the PIR-International Protein Sequence Database. To provide timely and high quality annotation and promote database interoperability, the PIR-International employs rule-based and classificationdriven procedures based on controlled vocabulary and standard nomenclature and includes status tags to distinguish experimentally determined from predicted protein features. The database contains about 200 000 non-redundant protein sequences, which are classified into families and superfamilies and their domains and motifs identified. Entries are extensively crossreferenced to other sequence, classification, genome, structure and activity databases. The PIR web site features search engines that use sequence similarity and database annotation to facilitate the analysis and functional identification of proteins. The PIR-International databases and search tools are accessible on the PIR web site at http://pir.georgetown.edu/ and at the MIPS web site at http://www.mips.biochem.mpg.de. The PIR-International Protein Sequence Database and other files are also available by FTP.
Differences in cardiac calcium release channel (ryanodine receptor) expression in myocardium from patients with end-stage heart failure caused by ischemic versus dilated cardiomyopathy. (1992)

The molecular basis for the systolic and diastolic dysfunction characteristic of end-stage heart failure in humans remains poorly understood. It has been proposed that both abnormal calcium handling and defects in the contractile apparatus may contribute to the myocardial dysfunction. Two channels, the calcium release channel (CRC) or ryanodine receptor of the sarcoplasmic reticulum (SR), and the slow calcium channel or dihydropyridine receptor (DHPR) of the transverse tubule, play key roles in regulating intracellular calcium concentration and in excitation-contraction (E-C) coupling in the heart. The DHPR serves as the voltage sensor and plasma membrane calcium channel resulting in activation of the CRC during E-C coupling in heart muscle. In this study, we investigated the levels of CRC expression in several forms of end-stage heart failure in humans. A cardiac CRC cDNA was cloned from rabbit and used as a probe for Northern blot analyses to determine mRNA levels in the left ventricles of normal (n = 4) and cardiomyopathic (n = 34) human hearts from patients undergoing cardiac transplantation. Compared with normal patients, patients with ischemic cardiomyopathy (n = 18) showed a 28% decrease in CRC mRNA levels (p less than 0.025) and patients with idiopathic dilated cardiomyopathy (n = 14) a nonsignificant 12% increase. In these same hearts, alpha-actin levels were unchanged in end-stage heart failure, as has been previously reported. This is the first report indicating that the expression of the CRC mRNA is abnormal in end-stage human heart failure.(ABSTRACT TRUNCATED AT 250 WORDS)
Transgenic UCP1 in white adipocytes modulates mitochondrial membrane potential (1999)

To test if mitochondrial uncoupling in white adipocytes is responsible for obesity resistance of the aP2-Ucp transgenic mice expressing ectopic uncoupling protein 1 (UCPI) in white fat, mitochondrial membrane potential (delta psi(m)) was estimated by flow cytometry in adipocytes isolated from gonadal fat. Ectopic UCP1 (approximately 0.8 mol UCP1/mol respiratory chain) decreased the delta psi(m) and rendered the potential sensitive to GDP and fatty acids. These ligands of UCP1 had no effect on delta psi(m) in white adipocytes from non-transgenic mice, suggesting that the function of endogenous UCP2 in adipocytes was not affected. The results support the hypothesis that mitochondrial uncoupling in white fat may prevent development of obesity.
Playful female skinscapes: body narrations of multilingual tattoos (2018)

Using oral narratives of tattoos and their bodily emplacement, the paper explores the performance of creativity, language and multilingualism, identity and gender among female students at three universities in South Africa. We draw on notions of skinscapes, the material culture of multilingualism and multimodality to illustrate, analyse and discuss the creativity and imagination of the design features of the assembled semiotic material that inspire the content and representations of the tattoo. We highlight the inspirations and explorative imaginations of the tattooed and/or the tattoo artists that enable their creations to be visually materialised and for new meanings to be constructed on the skin. We argue that multilingualism and identities should not just be seen in the inscribed languages on tattoos but in the totality of the material and verbal constituents that includes the languages spoken, heard and referred to in the context in which the artefact is reproduced and consumed. We conclude by emphasising the significance of looking at tattoos as material culture of multilingualism/multiculturalism deployed as a creative practice in meaning making. Skinscapes thus becomes a way of expanding sites within semiotic landscape research to include the human body.

Antilipolytic Actions of Vanadate and Insulin in Rat Adipocytes Mediated by Distinctly Different Mechanisms (1997)

Vanadate, which mimics the biological effects of insulin, also inhibits lipolysis in rat adipocytes. Here we demonstrate that the antilipolytic effect of vanadate differs from that of insulin at least by the five following criteria: 1) vanadate inhibits lipolysis mediated by high (supraphysiological) concentrations of catecholamines; 2) vanadate antagonizes (Bu)2cAMP-mediated lipolysis; 3) vanadate antagonizes isobutylmethylxanthine-dependent lipolysis, 4) vanadate inhibits lipolysis mediated by okadaic acid; and 5) wortmannin, which blocks the antilipolytic effect of insulin, fails to block vanadate-mediated antilipolysis. Vanadate does activate phosphoinositol 3-kinase, and wortmannin blocks this activation. Our working hypothesis assumes that all of the insulin-like effects of vanadate, including antilipolysis, are initiated by the inhibition of protein phosphotyrosine phosphatases (PTPases). Among documented PTPase inhibitors we found that VOSO4 (oxidation state +4), several organic vanadyl compounds (+4), zinc (Zn2+), tungstate (W), and molybdate (Mo) also had antilipolytic activity. The order of potency was vanadyl acetylacetonate ≥ VOSO4≥ NaVO3 ≥ vanadyl-dipicolinate > Zn2+» W > Mo, and it correlated better with the inhibition of adipose membranal-PTPases in cell-free experiments. We have concluded that the antilipolytic effect of vanadate is 1) mechanistically distinct from that of insulin, 2) independent of phosphoinositol 3-kinase activation, and 3) independent of the lipolytic cascade. We also strongly suggest that the antilipolytic effect of vanadate emanates from inhibiting adipose membranal, rather than cytosolic PTPases, and present preliminary data showing distinct differences in catalysis between these two PTPase categories. Overall, the study indicates that antilipolysis can be manifested via alternative, insulin-independent, signal-transducing pathways.
PREPARATION OF DIETHYL 1-BROMOALKYLPHOSPHONATES (1990)

Error-Controlled High Power Linear Amplifiers at YHF (1968)

Two amplifiers, each covering a different band in the VHF range, were constructed for test set applications. These amplifiers were required to meet stringent specifications beyond the general scope of previous art. These specifications related to the simultaneous availability of relatively large output power, tight linearity, minimal delay distortion across a 40 per cent band, high input and output return loss, large dynamic range, and time stability. The performance problems were solved by using: (i) Quadrature couplers in a corporate structure array to provide a high multiplicity of “paralleled” transistors, yielding both the power and return loss capabilities. (ii) The emitter follower configuration as the basic amplifier element, providing broad band, high level performance owing to the large self degeneration of that configuration. (iii) A “feed-forward,” instead of a feedback, system for error control and noise cancellation.
Folate Receptor Alpha Peptide Vaccine Generates Immunity in Breast and Ovarian Cancer Patients (2018)

<b>Purpose:</b> Folate receptor alpha (FR) is overexpressed in several cancers. Endogenous immunity to the FR has been demonstrated in patients and suggests the feasibility of targeting FR with vaccine or other immune therapies. CD4 helper T cells are central to the development of coordinated immunity, and prior work shows their importance in protecting against relapse. Our previous identification of degenerate HLA-class II epitopes from human FR led to the development of a broad coverage epitope pool potentially useful in augmenting antigen-specific immune responses in most patients.<b>Patients and Methods:</b> We conducted a phase I clinical trial testing safety and immunogenicity of this vaccine, enrolling patients with ovarian cancer or breast cancer who completed conventional treatment and who showed no evidence of disease. Patients were initially treated with low-dose cyclophosphamide and then vaccinated 6 times, monthly. Immunity and safety were examined during the vaccine period and up to 1 year later.<b>Results:</b> Vaccination was well tolerated in all patients. Vaccine elicited or augmented immunity in more than 90% of patients examined. Unlike recall immunity to tetanus toxoid (TT), FR T-cell responses developed slowly over the course of vaccination with a median time to maximal immunity in 5 months. Despite slow development of immunity, responsiveness appeared to persist for at least 12 months.<b>Conclusions:</b> The results demonstrate that it is safe to augment immunity to the FR tumor antigen, and the developed vaccine is testable for therapeutic activity in most patients whose tumors express FR, regardless of HLA genotype. <i>Clin Cancer Res; 24(13); 3014-25. ©2018 AACR</i>.
A new multi-code/multi-carrier DS-CDMA system (2002)

This paper presents a new multi-carrier DS-CDMA system with multi-code in which input data bits are first coded at a low rate (I/R) and resulting R coded binary bits are then multiplexed with a set of multi-codes to produce code division multiplexing (CDM) super-bits. After serial-to-parallel conversion, they are spread-spectrum transmitted using M orthogonal carriers. Based on a conventional matched-filter and RAKE receiver for each carrier, the performance is analyzed partially and simulated. The numerical results show that the proposed scheme has close bit error rate (BER) performance, but better anti-jamming ability compared to the normal multi-carrier DS-CDMA system.
Constant time neighbor finding in quadtrees: An experimental result (2008)

Neighbor finding is an important and a basic part of image processing in quadtrees. A constant time algorithm is proposed for neighbor finding in quadtrees in [1]. In this paper, empirical tests are given for the constant time algorithm in comparison with usual neighbor finding algorithm using quadtrees [2] and another constant time algorithm using linear quadtree [3]. Experiments using synthetic images simulating worst case situations show that the proposed algorithm is in constant time complexity while others are not. Even for experiments using natural images, the proposed algorithm is more than twice as fast as algorithm using quadtrees and is slightly as fast as algorithm using linear quadtrees.

Graphene/MnO<sub>2</sub> composite prepared by a simple method for high performance supercapacitor (2015)

MnO2 nanoparticles are anchored on the graphene nanosheets and make a graphene nanosheets/MnO2 (GMn) composite by thermal decomposition for application in supercapacitor. The GMn composite exhibits specific capacitance of 450 F g− 1 at 1 A g− 1, which is more than three times higher than that of as-prepared graphene sheets. Meanwhile, the composite shows excellent cycle stability without decline over 5000 cycles. The high electrochemical performance of the GMn electrodes is attributed to the prevention of graphene aggregation by the MnO2 nanoparticles, and the synergistic effects between graphene and MnO2 nanoparticles.
Nonlinear image enhancement to improve face detection in complex lighting environment (2006)

A robust and efficient image enhancement technique has been developed to improve the visual quality of digital images that exhibit dark shadows due to the limited dynamic ranges of imaging and display devices which are incapable of handling high dynamic range scenes. The proposed technique processes images in two separate steps: dynamic range compression and local contrast enhancement. Dynamic range compression is a neighborhood dependent intensity transformation which is able to enhance the luminance in dark shadows while keeping the overall tonality consistent with that of the input image. The image visibility can be largely and properly improved without creating unnatural rendition in this manner. A neighborhood dependent local contrast enhancement method is used to enhance the images contrast following the dynamic range compression. Experimental results on the proposed image enhancement technique demonstrates strong capability to improve the performance of convolutional face finder compared to histogram equalization and multiscale Retinex with color restoration without compromising the false alarm rate.
Hydration of Tricalcium Silicate:  Effects of CaCl<sub>2</sub> and Sucrose on Reaction Kinetics and Product Formation (2006)

The effects of CaCl2 and sucrose on the hydration of monoclinic and triclinic tricalcium silicate were studied using quasielastic neutron scattering and calorimetry. Aside from acceleration and retardation, other effects on the reaction were revealed including changes to the rate constant and the type and amount of hydration product. These effects were measured in terms of specific kinetic parameters for the first time. The phenomenon of “delayed acceleration” caused by sucrose is attributed to the solubilization of the silicate species.
Dereverberation by Linear Systems Techniques (1971)

A linear system approach is presented for the modeling of a stationary layered medium assuming representation by a finite number of thin layers and wave propagation normal to these layers. A linear recursive mathematical model is developed and a method for the identification of parameters is discussed. The results, although specifically derived for the processing of marine seismic data, are applicable to similar type problems in communications and remote sensing.
Multi-layer graphene field-effect transistors for improved device performance (2009)

We have noticed the importance of noise impacting the performances of nano-patterned graphene FETs. We performed the first experimental study on multi-layer graphene FETs to address the charge and current distribution. We have developed a model describing the coupling between graphene layers including interlayer screening effects. The model does not involve modification of the band structure for multiple-layer graphene. The model is in good agreement with the experimental results as well as previous studies on intercalated graphite structures. Noise reduction in few-layer graphene FETs can be understood within this model as well. For the above reason, we propose two or three-layer graphene to be a better choice for aggressively nano-patterned devices.
Material Balance and Boundary-Dominated Flow Models for Hydrate-Capped Gas Reservoirs (2006)

Abstract Gas hydrates are being considered as an alternative energy resource of the future, considering the enormous quantities existing in permafrost and offshore environments. Some of the hydrate reservoirs discovered (e.g., in Alaska and Siberia) are overlying a free-gas layer. These reservoirs are thought to be the easiest and probably the first type of hydrate reservoirs to be produced1. This paper presents the first-ever developed material balance model for such a reservoir (which we shall call a hydrate-capped gas reservoir). The technique presented herein differs from the traditional approach of applying material balance methods to conventional gas reservoirs because it includes the effects of gas generated from hydrate decomposition and its associated cooling effect. The material balance equation is developed by analytically and simultaneously solving the mass and energy balance equations. The solution yields the average reservoir pressure and the gas generated from hydrate decomposition as a function of cumulative gas produced, for a reservoir that is produced at a constant rate. In the second portion of the paper, we develop a flowing material balance equation by first writing the inflow performance equation, relating the wellbore pressure to the average reservoir pressure and then combining it with the material balance equation. This yields an estimate of initial gas-in-place from production data. Using a recently developed hydrate reservoir simulator, it is shown that this model is valid over a wide range of reservoir parameters. The success of this model relies on coupling of the energy and mass balance equations, where the energy equation accounts for the endothermic nature of hydrate decomposition. In its "forward solution" mode, the model developed here is used as an engineering tool for evaluating the role of hydrates in improving the productivity and extending life of hydrate-capped gas reservoirs. In addition, in its "backward solution" or inverse approach mode, the application of this new model is providing an estimate of initial free gas-in-place from production data.
