Vector vs. superscalar and VLIW architectures for embedded multimedia benchmarks (2002)

Multimedia processing on embedded devices requires an architecture that leads to high performance, low power consumption, reduced design complexity, and small code size. In this paper, we use EEMBC, an industrial benchmark suite, to compare the VIRAM vector architecture to superscalar and VLIW processors for embedded multimedia applications. The comparison covers the VIRAM instruction set, vectorizing compiler and the prototype chip that integrates a vector processor with DRAM main memory. We demonstrate that executable code for VIRAM is up to 10 times smaller than VLIW code and comparable to /spl times/86 CISC code. The simple, cache-less VIRAM chip is 2 times faster than a 4-way superscalar RISC processor that uses a 5 times faster clock frequency and consumes 10 times more power VIRAM is also 10 times faster than cache-based VLIW processors. Even after manual optimization of the VLIW code and insertion of SIMD and DSP instructions, the single-issue VIRAM processor is 60% faster than 5-way to 8-way VLIW designs.
Abl Kinases Regulate Actin Comet Tail Elongation via an N-WASP-Dependent Pathway (2005)

Microbial pathogens have evolved diverse strategies to modulate the host cell cytoskeleton to achieve a productive infection and have proven instrumental for unraveling the molecular machinery that regulates actin polymerization. Here we uncover a mechanism for Shigella flexneri-induced actin comet tail elongation that links Abl family kinases to N-WASP-dependent actin polymerization. We show that the Abl kinases are required for Shigella actin comet tail formation, maximal intracellular motility, and cell-to-cell spread. Abl phosphorylates N-WASP, a host cell protein required for actin comet tail formation, and mutation of the Abl phosphorylation sites on N-WASP impairs comet tail elongation. Furthermore, we show that defective comet tail formation in cells lacking Abl kinases is rescued by activated forms of N-WASP. These data demonstrate for the first time that the Abl kinases play a role in the intracellular motility and intercellular dissemination of Shigella and uncover a new role for Abl kinases in the regulation of pathogen motility.
Automated suggestions for miscollocations (2009)

One of the most common and persistent error types in second language writing is collocation errors, such as learn knowledge instead of gain or acquire knowledge, or make damage rather than cause damage. In this work-in-progress report, we propose a probabilistic model for suggesting corrections to lexical collocation errors. The probabilistic model incorporates three features: word association strength (MI), semantic similarity (via Word-Net) and the notion of shared collocations (or intercollocability). The results suggest that the combination of all three features outperforms any single feature or any combination of two features.
Reduced Reproductive Capacity in Diploid and Triploid Hybrid Sunfish (2000)

Reproductive capacity of 2-year-old sibling green sunfish Lepomis cyanellus male × bluegill L. macrochirus female diploid and triploid hybrids was investigated using histology and flow cytometry. Gonads of triploid females were immature compared with diploids, and gonads possessed cells that primarily appeared to be oogonia or immature oocytes; most cells were triploid. Gonadal development in triploid males appeared to be more advanced (based on observed cell types) than development in triploid females, although male triploids failed to yield milt during stripping. Some spermatozoa in triploid testes were completely differentiated, having tails. No cells, however, were less than 3n and most were 6n, which indicates that meiosis is interrupted at the first reduction division in male triploids but that some cells did complete spermiogenesis. Diploid male hybrids possessed a small proportion of haploid cells, and spermatozoa in their testes appeared normal. The largest proportion (more then 60%) of diploid hybrid testicular cells were 4n, but most cells (over 95%) appeared to be spermatozoa or spermatids, which suggests that there were problems with meiotic pairing during spermatogenesis in diploid hybrids. These results demonstrate that the production of haploid gametes did not occur in triploid hybrids and was diminished in diploid hybrids; the latter is possibly the result of a species isolation mechanism in a genus showing substantial natural interspecific hybridization.
A Performance Evaluation Tool for Drone Communications in 4G Cellular Networks (2019)

We introduce a measurement tool for the performance evaluation of wireless communications with drones over cellular networks. The Android software records various LTE parameters, evaluates the TCP and UDP throughput, and tracks the GPS position. Example measurement results are presented.
Inhibition of thymidine transport into phytohemagglutinin-stimulated lymphocytes by triterpenoids from Cimicifuga species. (1979)

Inhibitory effect of 24 triterpenoids from Cimicifuga spp. on lymphocyte blastformation with phytohemagglutinin (PHA) was studied. The results of this study provided a structure-activity relationship for potent suppressive activities. A hemiacetal group in the side chain, an oxygenated group in the C12 position, a cyclopropane ring on the B ring and a double bond at the C7 (8) position proved to be responsible for the activity. Cimicifugoside (I), which is endowed with all above mentioned functional groups to enhance the activity, was the strongest inhibitor of thymidine transport into PHA-stimulated lymphocytes. As little as 4 ng/ml cimicifugoside caused 50% inhibition of thymidine-3H uptake in the lymphocyte culture. Moreover, addition of the triterpenoid to mouse lymphosarcoma L-5178Y cell cultures resulted in a significant inhibition of transport of nucleosides into the cells, where neither cytotoxicity nor inhibition of the cell growth at higher concentration was observed. At same conditions, inhibitory activities of incorporation of leucine and glucosamine were not detected. These results indicate that the inhibition of thymidine uptake by cimicifugoside and its related compounds may not be due to the inhibition of DNA synthesis but on the membrane transport of nucleoside and/or nucleoside trapping mechanisms.

Magnetic bubbles and their applications (1972)

Magnetic bubble domains may be formed in platelets of certain magnetic materials. They are the basis for an unusual new breed of devices in which bubbles are selectively created, propagated, interacted, detected and annihilated, so that both memory and logic functions may be performed in a single piece of material. Bubble devices are very compact and dissipate little energy. This paper describes the nature of magnetic bubbles, and the materials which support them. Various aspects of device technology are introduced, with discussion of all the functions required, including bubble interaction logic. Applications for bubble devices are indicated.
Inflammasome-Mediated Autoinflammatory Disorders (2010)

The nucleotide-binding domain leucine-rich repeat containing (NLR) family of receptors are members of the innate immune system, and have a critical role in host defense. These molecules are key to driving inflammatory responses to abnormal cellular conditions. Many NLRs serve this role on activation by forming a multiprotein complex called an inflammasome. The inflammasome drives the processing and release of cytokines, such as the proinflammatory cytokines interleukin (IL)-1β and IL-18. Recently, the important function of NLR molecules in autoinflammatory disorders has been recognized, in part through the identification of the role of IL-1β in the pathogenesis of several autoinflammatory diseases. Cryopyrin-associated periodic syndromes were the first autoinflammatory disorders found to be directly mediated by dysfunctional inflammasome activation. This finding has subsequently led to studies in both murine models and humans that have revealed several other inflammatory conditions associated with activation of NLR-containing inflammasomes. Understanding the molecular pathophysiology of these autoinflammatory disorders has further guided the successful development of targeted therapy against IL-1. In this review, we provide an overview of the inflammasomes and describe the important role they play in the development and manifestation of autoinflammatory diseases.
The Relative Role of Gonadal Sex Steroids and Gonadotropin-Releasing Hormone Pulse Frequency in the Regulation of Follicle-Stimulating Hormone Secretion in Men (2008)

The sex steroid component of FSH negative feedback in men is mediated by E(2). Increasing GnRH frequency to castrate levels has no impact on FSH in the absence of sex steroids. When inhibin B levels are NL, sex steroids exert a modest effect on FSH.
Impact of Opportunistic Scheduling on Cooperative Dual-Hop Relay Networks (2010)

This letter advocates the performance of a multiuser relay network (MRN) equipped with a single amplify-and-forward (AaF) relay over Rayleigh fading environments. We derive new expressions for the cumulative distribution function (CDF) of the highest instantaneous end-to-end signal-to-noise ratio (SNR) taking into consideration the two cases of fixed gain relays and variable gain relays. Relying on these statistical results, we derive new expressions for the outage probability and symbol error rate (SER), both of which are obtained in exact closed form. Furthermore, we derive simple asymptotic outage probability and SER. Our asymptotic results confirm that opportunistic scheduling has no impact on the diversity order. We further prove that the array gain is what determines the SNR advantage of opportunistic scheduling over the single user scenario.
Mice with Cisplatin and Oxaliplatin-Induced Painful Neuropathy Develop Distinct Early Responses to Thermal Stimuli (2009)

We have therefore established a model of platinum drug-induced painful peripheral neuropathy that reflects the differences in early thermal pain responses that are observed in patients treated with either cisplatin or oxaliplatin. This model should be useful in studying the molecular basis for these different pain responses and in designing protective therapeutic strategies.
Outcome of pediatric patients with acute lymphoblastic leukemia/lymphoblastic lymphoma with hypersensitivity to pegaspargase treated with PEGylated <i>Erwinia</i> asparaginase, pegcrisantaspase: A report from the Children's Oncology Group (2017)

This small series of patients, nonetheless, provides data, suggesting preexisting immunogenicity against the PEG moiety of pegaspargase and poses the question as to whether PEGylation may be an effective strategy to optimize Erwinia asparaginase administration. Further study of larger cohorts is needed to determine the incidence of preexisting antibodies against PEG-mediated hypersensitivity to pegaspargase.
A Large Scale Interactive Holographic Display (2006)

Our work focuses on the development of interactive multi-user holographic displays that allow freely moving naked eye participants to share a three dimensional scene with fully continuous, observer independent, parallax. Our approach is based on a scalable design that exploits a specially arranged array of projectors and a holographic screen. The feasibility of such an approach has already been demonstrated with a working hardware and software 7.4M pixel prototype driven at 10-15Hz by two DVI streams. In this short contribution, we illustrate our progress, presenting a 50M pixel display prototype driven by a dedicated cluster hosting multiple consumer level graphic cards.
Influence of intramammary infusion of polymyxin B on the clinicopathologic course of endotoxin-induced mastitis (1983)

The influence of giving 1 dose of polymyxin B (1.6 X 10(6) U/quarter) by the intramammary route to dairy cows to modify the clinicopathologic course of mastitis induced by intramammary infusion of Escherichia coli endotoxin (1 mg/quarter) was examined. Pretreatment with polymyxin B or its simultaneous administration reduced and delayed the typical febrile and leukopenic responses to endotoxin infusion, prevented an increase in plasma lactate dehydrogenase activity and a reduction in plasma zinc concentration, but only marginally influenced the degree of udder inflammation and had no effect on leukocytosis in the milk. Intramammary infusion of polymyxin B at 30 or 60 minutes after endotoxin was infused prevented the increase in plasma lactate dehydrogenase activity and moderated the decrease in plasma zinc concentration, but otherwise failed to alter the clinicopathologic course of endotoxin-induced acute mastitis.
Recurrent papillary craniopharyngioma with BRAFV600E mutation treated with neoadjuvant-targeted therapy (2017)

Craniopharyngiomas are histologically benign but locally aggressive tumors in the sellar region that may cause devastating neurological and endocrine deficits. They tend to recur following surgery with high morbidity; hence, postoperative radiotherapy is recommended following sub-total resection. BRAFV600E mutation is the principal oncogenic driver in the papillary variant of craniopharyngiomas. Recently, a dramatic tumor reduction has been reported in a patient with BRAFV600E mutated, multiply recurrent papillary craniopharyngioma using a combination therapy of BRAF inhibitor dabrafenib and MEK inhibitor trametinib. Here, we report on near-radical reduction of a growing residual BRAFV600E craniopharyngioma using the same neoadjuvant therapy.
Anti-Inflammatory Preconditioning by Agonists of Adenosine A1 Receptor (2008)

Our data suggest that preconditioning by an A(1)R-agonist promotes the resolution of inflammation by inducing the production of A(2A)R. Future implications may include early treatment during inflammatory disorders or pretreatment before anticipated high risk inflammatory events, such as invasive surgery and organ transplantation.
Crystallization of Sodium Titanium Silicate with Sitinakite Topology:  Evolution from the Sodium Nonatitanate Phase (2004)

Titanium silicate (TS) with sitinakite topology and composition Na2Ti2O3SiO4·2H2O has received considerable attention because of its high ion-exchange selectivity toward cesium and strontium. In this paper we report the results of the studies of the crystallization process of TS with a combination of ex and in situ experiments. The effects of various parameters, such as gel composition, time, and temperature of the synthesis, on crystallinity and composition of the final product have been investigated. In situ X-ray powder diffraction studies carried out during the synthesis of TS revealed that the process begins with the formation of layered sodium nonatitanate (SNT) with chemical composition Na4Ti9O20·xH2O, which is also an excellent ion exchanger, selective for strontium and actinides. The pathway of transformation of SNT to the final product is sensitive to alkalinity of the starting gels. At high hydroxide concentration the reaction resulted in the formation of sodium titanium oxide silicate, Na2TiSiO5, which has the mineral natisite topology. This study has revealed a pathway for the synthesis of a combined SNT−TS exchanger for removal of Cs, Sr, and actinides by a single-step in-tank process.
BMP-2-Based Repair of Large-Scale Calvarial Defects in an Experimental Model (2008)

Pediatric craniofacial surgery is complicated by a shortage of autologous bone. Children between 2 and 10 years of age are especially problematic, as the dura has lost its potential to spontaneously heal large calvarial defects by approximately 2 years of age, and split calvarial grafts are often unavailable because of the underdeveloped diploic space until later childhood. We demonstrate the efficacy of a BMP-2-based system in repairing large-scale cranial defects in a rabbit model. Calvarial defects, 15 mm, were created in 18 adult New Zealand white rabbits, treated as follows: group 1, no repair (n = 6); group 2, absorbable collagen sponge (ACS) (n = 4); and group 3, recombinant human bone morphogenetic protein 2 delivered on ACS (rhBMP-2/ACS) (n = 8). Bone regeneration 6 weeks postoperatively was evaluated by 2- and 3-dimensional standard computed tomography, micro-computed tomography. Analysis of variance was performed using SPSS. The generated bone was also evaluated histologically. After 6 weeks, group 1 defects were on average 32.8% (SD, 8.8%) ossified. Group 2 defects were on average 34.4% (SD, 17.1%) ossified. Defects in group 3 were on average 96.9% (SD, 3.7%) ossified, significantly (P < 0.005) more than the defects in groups 1 and 2. rhBMP-2-induced bone was histologically and radiographically consistent with native bone. This study demonstrates the efficacy of rhBMP-2/ACS for the repair of calvarial defects in the rabbit model. rhBMP-2/ACS may offer a viable treatment option for craniofacial surgeons facing a shortage of bone, with the potential to replace autologous bone grafts and render their attendant morbidities obsolete.
A novel inexpensive device for the electrochemical generation of metallic emitters for field desorption (1977)

Details for the construction of a novel, inexpensive device for the electrochemical generation of metallic emitters for field desorption mass spectrometry are described. Use of the device for the generation of cobalt and nickel emitters is demonstrated.
Image analysis for automatic classification of MITOTIC cervical cells (1988)

To diagnose cervical cancer from biopsies, digital image analysis techniques and statistical discriminant analysis are use to identify mitotic cells, which are a marker of early cancer. Parameters extracted from each cell include areal and geometrical measures, optical density statistics, bending energy, and various statistical texture features. The discriminant analysis attempts to classify mitotic cells from those in interphase on the basis of the image analysis output data vectors using prescored classifications. The first comprehensive trial of the imaging technique for a dataset of 32 cervical cells showed that 88% of the cells could be properly identified automatically.< <ETX>></ETX>
Broadside radiation from periodic leaky-wave antennas (1993)

A double-strip grating leaky-wave antenna consisting of two strips per unit cell is analyzed. The stopband behavior exhibited at broadside scan in the single-strip grating antenna is characteristic of all periodic leaky-wave antennas having a single strip per unit cell, and results in a drastic increase in the attenuation rate of the leaky wave as the beam is scanned to broadside. By nearly eliminating this stopband behavior, the double-strip leaky-wave antenna can scan from backward end fire to forward end fire without any large frequency regions of high attenuation. An approximate design rule for the double-strip antenna is discussed, and results are presented to show how the antenna may be further optimized to achieve the minimum possible variation in attenuation as the beam is scanned through broadside. Although the stopband behavior is never completely eliminated with the addition of the extra strip, the optimum design shows an almost negligible region of rapidly varying attenuation near broadside.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Head-tracking virtual 3-D display for mobile devices (2012)

Computer vision enables camera data to be utilized in user interfaces to analyze the 3-D context and automatically detect the user intentions. Using cameras as an input modality provides single-handed operations in which the users' actions are recognized without interactions with the screen or keypad. In this context, we have constructed a real-time mobile application prototype where the user's position and gaze is determined in real time, a technique that enables the display of true three-dimensional objects even on a typical 2-D LCD screen. We have defined a series of interaction methods where the user's motion and camera input realistically control the viewpoint on a 3-D scene. The head movement and gaze can be used to interact with hidden objects in a natural manner just by looking at them. We provide a description of the embedded implementation at a system-level where we highlight the application development challenges and trade-offs that need to be dealt with battery powered mobile devices. The implementation includes a parallel pipeline that reduces the latencies of the application.
