Array placement for storage size reduction in embedded multimedia systems (2002)

In this paper we present the second stage of a two-phase strategy for reducing the required background memory sizes for a large class of data-intensive multimedia applications. This strategy is particularly useful in an embedded application context, where memory size and the corresponding power consumption are the main cost factors together with data transfers. Our strategy optimizes the storage order of arrays in memory by trying to improve the reuse of memory locations, as well for elements of the same array as for elements of different arrays. Although size reduction is the main objective, an added benefit is a reduced power consumption due to the decreased capacitive load of the memories. The memory size reduction task is part of an overall memory size and power reduction methodology called ATOMIUM in which other tasks can increase its effectiveness (e.g. loop, transformations), but it can also be used on a stand-alone base. The effectiveness of our approach is demonstrated by experimental results for some real-life multimedia applications, for which a considerable memory size reduction was obtained.
Demo: AntMonitor (2015)

Mobile devices play an essential role in the Internet today, and there is an increasing interest in using them as a vantage point for network measurement from the edge. At the same time, these devices store personal, sensitive information, and there is a growing number of applications that leak it. We propose AntMonitor-- the first system of its kind that supports (i) collection of large-scale, semantic-rich network traffic in a way that respects users' privacy preferences and (ii) detection and prevention of leakage of private information in real time. The first property makes AntMonitor a powerful tool for network researchers who want to collect and analyze large-scale yet fine-grained mobile measurements. The second property can work as an incentive for using AntMonitor and contributing data for analysis. As a proof-of-concept, we have developed a prototype of AntMonitor, deployed it to monitor 9 users for 2 months, and collected and analyzed 20 GB of mobile data from 151 applications. Preliminary results show that fine-grained data collected from AntMonitor could enable application classification with higher accuracy than state-of-the-art approaches. In addition, we demonstrated that AntMonitor could help prevent several apps from leaking private information over unencrypted traffic, including phone numbers, emails, and device identifiers.
Vector Approximate Message Passing (2016)

The standard linear regression (SLR) problem is to recover a vector $\mathbf{x}^0$ from noisy linear observations $\mathbf{y}=\mathbf{Ax}^0+\mathbf{w}$. The approximate message passing (AMP) algorithm recently proposed by Donoho, Maleki, and Montanari is a computationally efficient iterative approach to SLR that has a remarkable property: for large i.i.d.\ sub-Gaussian matrices $\mathbf{A}$, its per-iteration behavior is rigorously characterized by a scalar state-evolution whose fixed points, when unique, are Bayes optimal. The AMP algorithm, however, is fragile in that even small deviations from the i.i.d.\ sub-Gaussian model can cause the algorithm to diverge. This paper considers a "vector AMP" (VAMP) algorithm and shows that VAMP has a rigorous scalar state-evolution that holds under a much broader class of large random matrices $\mathbf{A}$: those that are right-orthogonally invariant. After performing an initial singular value decomposition (SVD) of $\mathbf{A}$, the per-iteration complexity of VAMP can be made similar to that of AMP. In addition, the fixed points of VAMP's state evolution are consistent with the replica prediction of the minimum mean-squared error recently derived by Tulino, Caire, Verdú, and Shamai. Numerical experiments are used to confirm the effectiveness of VAMP and its consistency with state-evolution predictions.
Super-High Resolution Holographic Materials For UV And XUV Applications (1989)

Recent progress in UV and XUV optics has been accelerated as a result of development of new holographic materials based on graft concept. Using the new polymeric materials, holographic optical elements (HOEs) can be recorded in the visible and reconstructed in the UV and XUV region, with diffraction efficiencies higher than 95% for UV HOEs and 25% for XUV HOEs. The new series of high resolution (20,000 1/mm) and high refractive index modulation (&Delta;n = 0.2) materials consist of extremely dense photochemical crosslinking network of hydroxyalkyl acrylate-methacrylates, hard dichromated gelatin, and transparent PVA.

Circulating angiogenic factors in a rat model of preeclampsia (2010)

Objective We studied the angiogenic factors in our rat model of preeclampsia (PE) in which marinobufagenin (MBG, a bufodienolide) plays an important role. Methods Animals were grouped into: normal, non‐ pregnant (C); normal pregnant (NP); NP injected weekly with DOCA intraperitoneally (IP) and whose drinking water was replaced with 0.9% saline (PDS); NP given daily injections of MBG (0.765 μg/100g) once pregnancy was established; PDS given daily injections of resibufogenin [RBG, an antagonist of MBG (30 μg/kg/day)] IP from day 4 of pregnancy (PDSR). The angiogenic factors were measured on 3–5, 7–10 &amp; 17–20 days of gestation. We have previously shown that MBG levels are already elevated in this model at the 3–5 day time period and remain elevated throughout gestation in PDS rats. Summary of Results At 3–5 days of pregnancy, there was no angiogenic imbalance. At the 7–10 day period, plasma PlGF was greater in the NP than in the PDS. The sFlt‐1/PlGF as well as the placental Flt‐1 and Flt‐1/PlGF were greater in the PDS rats than in NP (p&lt;0.05). These findings were also present at the 17–20 day time point. The levels of these factors in PDSR were similar to those in NP. Conclusions Angiogenic imbalance contributes to the pathogenesis of the preeclamptic syndrome in our rat model. MBG elevation precedes this alteration in angiogenic factors. This is confirmed by prevention of this imbalance in this study by pretreatment with RBG. Scott, Sherwood/Brindley Foundation.
Spectroscopic ellipsometry and band structure of Si{sub 1{minus}y}C{sub y} alloys grown pseudomorphically on Si (001) (1995)

The authors have measured the dielectric functions of three Si{sub 1{minus}y}C{sub y} alloys layers (y {le} 1.4%) grown pseudomorphically on Si (001) substrates using molecular beam epitaxy at low temperatures. From the numerical derivatives of the measured spectra, they determine the critical point energies E{sub 0}{prime} and E{sub 1} as a function of y (y {le} 1.4%) using a comparison with analytical line shapes and analyze these energies in terms of the expected shifts and splittings due to negative hydrostatic pressure, shear stress, and alloying. Their data agree well with the calculated shifts for E{sub 1}, but the E{sub 0}{prime} energies are lower than expected. They discuss their results in comparison with recent tight-binding molecular dynamics simulations by Demkov and Sankey predicting a total breakdown of the virtual-crystal approximation for such alloys.
Inhibition of Helicobacter pylori urease by omeprazole (1993)

Objectives To investigate the effect of the proton pump inhibitor omeprazole on the function of purified urease enzyme of Helicobacter pylori and to examine the in vitro activities of omeprazole against urease-positive and -negative Helicobacter strains. Methods Urease was purified chromatographically from H. pylori. The effect of omeprazole on urease enzyme activity was assayed spectrophotometrically after incubation with urea substrate, phenol red indicator and 3mmol/l phosphate buffer. Minimal inhibitory concentrations of omeprazole against H. pylori and other Helicobacter species were determined using an agar dilution assay. Results Omeprazole was found to inhibit the enzyme activity of purified H. pylori urease in a dose-dependent manner. In vitro growth of both urease-positive and mutant urease-negative H. pyloristrains was equally inhibited by omeprazole. Conclusions Whilst omeprazole competitively inhibits the urease enzyme in vitro, urease enzyme inhibition does not account for the in vitro susceptibility of H. pylori to proton pump inhibitors. Urease inhibition by omeprazole in vivo, however, could increase the effectiveness of antibiotics. It may also affect the reliability of the urease-based tests used to assess H. pylori status.
A fast-locking harmonic-free digital DLL for DDR3 and DDR4 SDRAMs (2016)

A new digital delay-locked loop (DLL) for DDR3/DDR4 SDRAM is presented. The proposed digital DLL employs a new noise-tolerant triple (MSB-interval + binary + sequential) search algorithm for implementing a harmonic-free, fast-locking capability while retaining low jitter, low power performance, and a wide operating frequency range. The proposed DLL with duty-cycle correction is designed using a 38-nm CMOS process and occupies an active area of just 0.02 mm2. The DLL operates over a frequency range of 0.3–2.0 GHz and achieves a peak-to-peak jitter of 7.78 ps and dissipates 3.48 mW from a 1.1 V supply at 1 GHz.
Molecular Differentiation and Antifungal Susceptibility of Candida albicans Isolated from Patients with Respiratory Infections in Guiyang Medical College Hospital, China (2009)

Genetic heterogeneity and drug susceptibility patterns of 43 Candida albicans isolates from patients with respiratory infections in China were compared with those of 52 isolates from Japanese patients. Of the 43 strains, 17 were genotype A, 17 were genotype B, 8 were genotype C, and 1 was genotype E. Drug susceptibilities against amphotericin B, flucytosine, 3 azoles, and micafungin of the 43 strains and the 52 Japanese isolates were compared. All strains in China were susceptible to all drugs tested, and susceptibility patterns of the two countries were similar. Four Japanese isolates showed trailing growth for azole antifungals; Chinese strains did not.
Spectral broadening of ultraviolet dispersive waves in gas-filled hollow-core fiber using pump pulse modulation (2020)

UV supercontinuum laser sources based on resonant dispersive wave (RDW) generation in gas-filled hollow-core (HC) fibers offer an attractive architecture for numerous applications. However, the narrow UV spectral peak inherent to RDW generation limits the suitability for applications that require broad spectral coverage within the UV region such as spectroscopic scatterometry. In this Letter, we demonstrate how the UV spectrum can be shaped by modulating the peak power of the pump pulses driving the RDW generation, thereby creating a broadened and flattened UV spectrum. Using an argon-filled anti-resonant HC fiber, we generate a UV spectrum with a center wavelength of 323.6 nm with an FWHM of 51.7 nm, corresponding to a relative bandwidth of 16.1%.

Population-Wide Model-Free Quantification of Blood-Brain-Barrier Dynamics in Multiple Sclerosis (2011)

The processes by which new white matter lesions in multiple sclerosis (MS) develop are only partially understood. Recently developed lesions tend to enhance on magnetic resonance imaging (MRI) scans following the intravenous administration of a contrast agent. In this paper, we develop a model-free framework for the analysis of these data that provides biologically meaningful quantification of this blood-brain barrier opening.

Vis‐sensitive photopolymer containing vinyl ether compound and pyrromethene dye (2002)

Abstract A visible light(vis)‐sensitive photoresist based on the concept of chemical amplification was developed utilizing poly(p‐hydroxystyrene) (PHS), 2,2‐bis[4‐(2‐(vinyloxy)‐ethoxy)phenyl]propane (BPA‐DEVE) as a crosslinking agent, N‐trifluoromethylsulfonyloxy‐1,8‐naphthalimide (NIT) as a photoacid generator (PAG) and pyrromethene dyes such as 1,3,5,7,9‐pentamethylbipyrromethene difluoroborate (PRH) and 2,8‐diethyl‐1,3,5,7,9‐pentamethylbipyrromethene difluoroborate (PRE) and 3,3′‐carbonylbis(7,7′‐diethylaminocoumarin) (KCD). On irradiation with an argon ion laser, the photopolymer comprising PRH and PRE exhibited a high sensitivity of 65 and 46 mJ cm −2 , respectively. It is suggested that the sensitization mechanism of the pyrromethene dye/PAG system involves singlet electron transfer. The sensitivity of the photoresist increased with the decreasing molecular weight of PHS because of the high dissolution rate. Copyright © 2002 John Wiley &amp; Sons, Ltd.
Recovering Signal Energy From the Cyclic Prefix in OFDM (2008)

In orthogonal frequency-division multiplexing (OFDM) systems, a cyclic prefix (CP) is often added at the transmitter and discarded at the receiver. When the length of the CP exceeds the delay spread of the channel, a portion of the CP can be used to recover additional signal energy. In the past, Nyquist windowing techniques have been proposed to recover signal energy, thereby improving performance. In this paper, linear maximum-likelihood (ML) and minimum-mean-square-error (MMSE) approaches are developed, which further improve performance, particularly when the signal-to-noise ratio (SNR) is low. Simpler two-valued windowing (TVW) solutions are also provided, which generally employ one or two non-Nyquist windows.
Generation of Transgenic Mosquitoes Harboring a Replication-Restricted Virus (2022)

Live microbe vaccines are designed to elicit strong cellular and antibody responses without developing the symptoms of the disease, and these are effective in preventing infectious diseases. A flying vaccinator (also known as a flying syringe) is a conceptual, genetically engineered hematophagous insect that is used to deliver vaccines such as an antigen from a parasite produced in mosquito saliva; bites from such insects may elicit antibody production by immunizing the host with an antigen through blood-feeding. In addition to a simple vaccine antigen, a flying vaccinator may potentially load a live attenuated microbe with an appropriate mechanism for sustaining its constitutive proliferation in the insect. In this study, a recombinant vesicular stomatitis virus (VSV) lacking the glycoprotein gene ( VSV-G ) was used to produce replication-restricted VSV (rrVSV) containing GFP. Transgenic Anopheles stephensi mosquitoes, in which the salivary glands expressed a VSV-G gene driven by an aapp salivary gland-specific promoter, were generated and injected intraperitoneally with rrVSV. The injected rrVSV entered the cells of the salivary gland and stimulated endogenous production of progeny rrVSV particles, as seen in rrVSV-infected Drosophila melanogaster expressing VSV-G . These data suggested the possibility of developing a valuable tool for delivering genetically attenuated virus vaccines via mosquito saliva, although efficient replication-restricted virus production is required.
The Expression of von Willebrand Factor-Binding Protein Determines Joint-Invading Capacity of Staphylococcus aureus, a Core Mechanism of Septic Arthritis (2020)

Septic arthritis, one of the most dangerous joint diseases, is predominantly caused by <i>Staphylococcus aureus</i> In contrast, coagulase-negative staphylococci are rarely found in septic arthritis. We hypothesize that coagulases released by <i>S. aureus</i>, including coagulase (Coa) and von Willebrand factor-binding protein (vWbp), play potent roles in the induction of septic arthritis. Four isogenic <i>S. aureus</i> strains differing in expression of coagulases (wild-type [WT] Newman, Δ<i>coa</i>, Δ<i>vwb</i>, and Δ<i>coa</i> Δ<i>vwb</i>) were used to induce septic arthritis in both wild-type and von Willebrand factor (vWF)-deficient mice. Septic arthritis severity was greatly reduced when wild-type mice were infected with the Δ<i>coa</i> Δ<i>vwb</i> and Δ<i>vwb</i> variants compared to WT or Δ<i>coa</i> strains, suggesting that vWbp rather than Coa is a major virulence factor in <i>S. aureus</i> septic arthritis. vWF-deficient mice were more susceptible to bone damage in septic arthritis, especially when the Δ<i>vwb</i> strain was used. Importantly, no difference in arthritis severity between the Δ<i>vwb</i> and WT strains was observed in vWF-deficient mice. Collectively, we conclude that vWbp production by <i>S. aureus</i> enhances staphylococcal septic arthritis.<b>IMPORTANCE</b> Septic arthritis remains one of the most dangerous joint diseases with a rapidly progressive disease character. Despite advances in the use of antibiotics, permanent reductions in joint function due to joint deformation and deleterious contractures occur in up to 50% of patients with septic arthritis. So far, it is still largely unknown how <i>S. aureus</i> initiates and establishes joint infection. Here, we demonstrate that von Willebrand factor-binding protein expressed by <i>S. aureus</i> facilitates the initiation of septic arthritis. Such effect might be mediated through its interaction with a host factor (von Willebrand factor). Our finding contributes significantly to the full understanding of septic arthritis etiology and will pave the way for new therapeutic modalities for this devastating disease.
Consequences of Dispersity on the Self-Assembly of ABA-Type Amphiphilic Block Co-Oligomers (2018)

Intriguingly, little is known about the impact of dispersity on the crystallization driven self-assembly (CDSA) of amphiphilic block copolymers in aqueous media. Here, we investigate the influence of dispersity on the CDSA of ABA-type amphiphilic block co-oligomers (ABCOs). Two pairs of ABCOs are synthesized comprising discrete (<i>Đ</i> = 1.00) or disperse (<i>Đ</i> = 1.20) isotactic l-lactic acid 16-mers as the semicrystalline hydrophobic block and either oligo(ethylene glycol) methyl ether (MeOoEG) or oligo(tetraethylene glycol succinate) (oTEGSuc) as the discrete hydrophilic block. Self-assembly studies in water with 10% THF reveal uniform nanofibers/2D sheets for the discrete oligomers, but such structural regularity is largely compromised in the disperse oligomers. The results are corroborated by sharp melting transitions in both solution and bulk for the discrete ABCOs, unlike their disperse analogues that show a lack of crystallization. Interestingly, the discrete MeOoEG-LLA oligomer reveals crystallization driven gelation, illustrating the contrasting differences between the discrete oligomers and their disperse counterparts.
A novel TDM method for serrodyne modulation with high sideband suppression for arbitrary waveform generation (2005)

A novel TDM approach has been incorporated with serrodyning to shift the frequency of an arbitrary carrier up to /spl plusmn/1 MHz with highest sideband suppression ever reported. This technique also realizes endless phase modulation.
ParLe&amp;#8212;A Parallel Computing Learning Set for MPSOCs/NOCs (2005)

Programming and design skills in parallel computing related to systems on chip (SOC) will become increasingly important since future SOCs will have multiple processors interconnected via on-chip networks (NOC). Unfortunately there exist no easy-to-use tools for learning and experimenting with multiprocessor (MP)SOCs/NOCs, but one must use ad-hoc combinations of tools, methodologies and sample applications from very different sources. In this paper we introduce a parallel computing learning set (Parle) for configurable shared memory MPSOCs/NOCs and corresponding theoretical parallel random access machines (PRAM). The learning set consists of an experimental optimizing compiler for high-level parallel programming language e and assembler, linker, loader, simulator with a graphical user interface and statistical tools, and sample e/assembler code. Using the set, a student/designer can easily ivrite simple parallel programs, compile and load them into a configurable MPSOC/NOC platform, execute/debug them, gather statistics and explore the performance, utilization, and gate count estimations with different architectural parameters. The learning set runs on Mac OS X systems and is available for non-profit educational purposes.

Effect of passive myocardium on the compliance of porcine coronary arteries (2003)

The objective of this study was to determine the effect of passive myocardium on the coronary arteries under distension and compression. To simulate distension and compression, we placed a diastolic-arrested heart in a Lucite box, where both the intravascular pressure and external (box) pressure were varied independently and expressed as a pressure difference (DeltaP = intravascular pressure - box pressure). The DeltaP-cross-sectional area relationship of the first several generations of porcine coronary arteries and the DeltaP-volume relationship of the coronary arterial tree (vessels >0.5 mm in diameter) were determined using a video densitometric technique in the range of +150 to -150 mmHg. The vasodilated left anterior descending (LAD) coronary artery of six KCl-arrested hearts were perfused with iodine and 3% Cab-O-Sil. The intravascular pressure was varied in a triangular pattern, whereas the absolute cross-sectional area of each vessel and the total arterial volume were calculated using video densitometry under different box pressures (0, 50, 100, and 150 mmHg). In the range of positive DeltaP, we found that the compliance of the proximal LAD artery in situ (4.85 +/- 3.8 x 10-3 mm2/mmHg) is smaller than that of the same artery in vitro (16.5 +/- 6 x 10-3 mm2/mmHg; P = 0.009). Hence, the myocardium restricts the compliance of the epicardial artery under distension. In the negative DeltaP range, the LAD artery does not collapse, whereas the same vessel readily collapses when tested in vitro. Hence, we conclude that myocardial tethering prevents collapse of large blood vessel under compression.
Sorbent Augmented Hemodialysis Systems (2009)

Recent publications have reintroduced the concept of using sorbent systems to augment the efficiency of the dialysis process, either by making stationary or compact wearable devices to regenerate dialysis fluid or to target larger molecules for removal by direct blood or plasma contact with sorbent particles. Many of the inherent problems associated with older sorbents have been overcome by designing sorbents with improved biocompatibility and potential for removing molecules beyond the limits of conventional dialysis membranes. One system is approved for use in acute renal failure in the United States, but other devices are not approved for use in humans and continue to be tested in animals and humans. A prototype wearable sorbent device under investigation is not yet able to meet acceptable small molecular weight solute removal, and the other sorbent devices that possess the ability to remove unconventional uremic toxins have not been studied sufficiently in dialysis patients to define their role as augmentation devices. That there is a renewal of interest in sorbents in augmentation of dialysis points to the dissatisfaction with current dialysis technology.
