Tarazu (2012)

Data center-scale clusters are evolving towards heterogeneous hardware for power, cost, differentiated price-performance, and other reasons. MapReduce is a well-known programming model to process large amount of data on data center-scale clusters. Most MapReduce implementations have been designed and optimized for homogeneous clusters. Unfortunately, these implementations perform poorly on heterogeneous clusters (e.g., on a 90-node cluster that contains 10 Xeon-based servers and 80 Atom-based servers, Hadoop performs worse than on 10-node Xeon-only or 80-node Atom-only homogeneous sub-clusters for many of our benchmarks). This poor performance remains despite previously proposed optimizations related to management of straggler tasks. In this paper, we address MapReduce's poor performance on heterogeneous clusters. Our first contribution is that the poor performance is due to two key factors: (1) the non-intuitive effect that MapReduce's built-in load balancing results in excessive and bursty network communication during the Map phase, and (2) the intuitive effect that the heterogeneity amplifies load imbalance in the Reduce computation. Our second contribution is Tarazu, a suite of optimizations to improve MapReduce performance on heterogeneous clusters. Tarazu consists of (1) Communication-Aware Load Balancing of Map computation (CALB) across the nodes, (2) Communication-Aware Scheduling of Map computation (CAS) to avoid bursty network traffic and (3) Predictive Load Balancing of Reduce computation (PLB) across the nodes. Using the above 90-node cluster, we show that Tarazu significantly improves performance over a baseline of Hadoop with straightforward tuning for hardware heterogeneity.

Persistence of antibodies for 42 months following vaccination of adolescents with a meningococcal serogroups A, C, W-135, and Y tetanus toxoid conjugate vaccine (MenACWY-TT) (2012)

These results indicate that seroprotection following primary vaccination with MenACWY-TT extends more than 3 years. Ongoing persistence data are required to understand the duration of protection following vaccination and to guide decisions on the need for future booster doses.
A perspective on dose-intensive therapy with autologous bone marrow transplantation for solid tumors. (1991)

The poor results seen in patients with advanced solid tumors treated with conventional-dose therapy have stimulated interest in alternative approaches, including higher than standard doses of chemotherapy. Most chemotherapeutic agents exhibit a steep dose-response curve in laboratory models that is log linear in nature. Autologous bone marrow transplantation applies this concept by employing dose-intensive therapy with chemotherapeutic agents whose dose-limiting toxicity is myelosuppression. Alkylating agents are logical choices for high-dose chemotherapy because they have a steep dose-response curve both in vitro and in vivo, and this response is maintained through multiple logs of tumor cell kill. Although at conventional doses myelosuppression is dose-limiting, at transplant doses each agent has its particular dose-limiting organ toxicity which allows alkylating agents to be employed in combination.
Blind adaptive multiuser detection in multipath CDMA channels based on subspace tracking (1998)

A blind adaptive technique for signal demodulation in multipath code-division multiple-access (CDMA) communication channels is proposed. This technique is based on signal subspace estimation. The receiver employs a bank of linear filters (decorrelating filters or linear MMSE filters) at the front end to mitigate the multiple-access interference and the multipath interference. A channel estimator is used to estimate the channel state for diversity combining. It is shown that through the use of signal subspace estimation, both the decorrelating filterbank and the linear MMSE filterbank can be obtained blindly, i.e., they can be estimated from the received signal with the prior knowledge of only the signature waveform of the desired user. Two forms of the subspace-based linear filterbanks are developed and their equivalence in terms of the interference suppression capability is established. These subspace-based blind adaptive interference suppression techniques require, at each symbol epoch, the eigenvalues and the eigenvectors of an appropriate signal subspace, which ran be obtained using computationally efficient sequential adaptive eigendecomposition (subspace tracking) algorithms. Moreover, a blind adaptive method for estimating the channel state is developed, which also produces the postcombining decision statistic as a byproduct.
Electrochemical Graphitization: An Efficient Conversion of Amorphous Carbons to Nanostructured Graphites (2017)

This concept paper describes a new electrochemical method for the graphitization of amorphous carbons. The graphitization is achieved by a simple cathodic polarization of the carbons at merely ≈1100 K in molten CaCl<sub>2</sub> . This electrochemical process is applicable to both graphitizable and non-graphitizable carbons, generating porous graphitic structures of high-crystallinity nanosheets. The transformation of carbon blacks, microspheres, and fibers to porous graphites, hollow graphite spheres, and pipes with porous shells have been demonstrated and the potential graphitization mechanism discussed.
Synthesis and Evaluation as Irreversible Glycosidase Inhibitors of Mono‐ and Oligo(glycosylthio)benzoquinones (1994)

Abstract The mono(glucosylthio)hydroquinone 2 was prepared by S ‐glycosidation of 2‐mercaptobenzene‐1,4‐diol and by addition of the acetylated 1‐thioglucose 3 to benzo‐1,4‐quinone ( Scheme 1 ). The second, higher yielding procedure was adopted for the preparation of a range of (glucosylthio)hydroquinones. Addition of 3 to 2‐chlorobenzo‐1,4‐quinone, followed by oxidation gave the 1‐thioglucosides 7 and 12 (1.3:1), while addition of HCl to the (glucosylthio)quinone 4 and oxidation gave mainly 12 ( Scheme 1 ). Similarly, the bis(glucosylthio)hydroquinone 33 was obtained from 3 and 4 ( Scheme 4 ), and the (cellobiosylthio)hydroquinone 18 from the thiol 16 and benzo‐1,4‐quinone ( Scheme 2 ). Addition of the 4‐thioglucoside 21 to benzo‐1,4‐quinone (→ 22 ) and to 4 was followed by oxidation to yield the mono(glucosylthio)quinone 23 and the disubstituted quinones 24 and 25 , respectively ( Scheme 3 ). A mixture 24 / 25 was also obtained from the addition of 3 to 23 . The tris(glucosylthio)hydroquinone 36 was obtained by addition/elimination to the dichloroquinone 29 or the dimesylate 31 , which was prepared in a simplified way ( Scheme 4 ). The tetrakis(glucosylthio)hydroquinone 37 was obtained from 3 and chloranil, followed by reduction. The acylated hydroquinones were deprotected (→ 5, 9, 14, 19, 27, 34 , and 38 ), and oxidized to the corresponding quinones ( 6, 10, 15, 20, 28, 35 , and 40 ). The (glucosylthio)quinones 6, 15, 20, 28 , and 35 were tested as time‐dependent inactivators of a retaining β‐1,4‐glucosidase from Agrobacterium faecalis ( Abg ), which has a strong exo‐glucosidase action ( Table 1 ). Similarly, compounds 20, 28 , and 35 were tested with a cellulase from Cellulomonas fimi ( Cex ) which degrades cellulose and cellooligosaccharides by hydrolysis of a cellobiose unit from the nonreducing terminus. The most effective inactivators for Abg were 6, 15 , and 35 , which inactivated this enzyme with similar second‐order rate constants. (Glycosylthio)quinone 28 was the worst inactivator and did not show normal saturation behaviour. Inactivation of Cex by the (glycosylthio)quinones was 3–500 times slower than that of Abg . The three inactivators 20, 28 , and 35 had approximately the same efficacy with Cex , suggesting that they bind to this enzyme in a similar mode. Further, the K i values observed are very similar to K m values measured for aryl cellobiosides, implying that they bind at the active site.
Infrared-Sensitive Photorefractive Polymer Composite Devices (2007)

Abstract : The main goal of the effort was to develop high performing photorefractive (PR) polymer composites working at 1 micrometer by one photon photorefractivity and two photon photorefractive devices operating at 1.5 micrometers. The utilization of these photorefractive devices for beam cleanup and reconstruction of aberrated images was also an important objective of the effort. We have accomplished these goals by developing highly efficient one photon sensitive photorefractive devices operating at about 1 micrometer with high diffraction efficiency, near video rate response time and high two beam coupling gain. This is the first time demonstration of an all-organic photorefractive material beyond 830 nanometers and the results are the best among any near-infrared photorefractive materials under similar experimental conditions.
La morfologia verbal de subjuntiu al Segrià: estudi prospectiu (1993)

En sociolinguistica de la variacio mirem d'establir avaluacions sobre el paper dels factors socials en la diferent imposicio de les variables linguistiques en l'us real de la llengua. Pero no s'acostuma a establir avaluacions sobre la influencia dels factors purament linguistics, estructurals, quant al grau d'imposicio de les innovacions. El present article ofereix els resultats globals d'un estudi dut a terme aplicant en bona mesura aquesta darrera perspectiva, sobre la imposicio de les formes estandards (davant les dialectals) en la morfologia de mode subjuntiu en la comarca del Segria (acabaments en tema -i, davant acabaments en tema -o). Estudi que ve a donar compte del fet que aquestes formes s'imposen en mesures diferents segons les persones verbals (menys en la primera i mes en la tercera) i segons les conjugacions (menys en la primera i mes en la resta), a banda de la diferent imposicio segons els grups socials (mes en dones i persones joves i menys en homes i persones grans). Cal deixar clar que es tracta d'un estudi prospectiu, no pas definitiu.

Hydrated nickel oxide films: electrochemical and related physical properties (1990)

The electrochemistry of hydrated nickel oxides (NiOxHy) has been an active field of research , principally due to the use of these materials as the positive electrode in secondary nickel/cadmium batteries. Sintered plate materials", as well as electrochemically' and chemically' grown thin films have been studied; the published literature is reviewed in refs. 4 and 5. However, and in spite of the great effort in this direction, some important aspects of the electrochemical behaviour of these materials remain still unclear. Among then'', one could emphasize the mechanism of the electrochemical reaction as a whole, the mechanism by which diffusion of the ions into the film occurs, the role of water molecules incorporated in the film structure, and the dependence of the electrochemical properties on the film microstructure.
Protection, usability and improvements in reflected XSS filters (2012)

Due to the high popularity of Cross-Site Scripting (XSS) attacks, most major browsers now include or support filters to protect against reflected XSS attacks. Internet Explorer and Google Chrome provide built-in filters, while Firefox supports extensions that provide this functionality. However, these filters all have limitations.
The micelle to vesicle transition of lipids and detergents in the presence of a membrane protein: towards a rationale for 2D crystallization (1996)

The assembly of two-dimensional membrane protein crystals in the presence of lipids was analyzed with quasielastic light scattering and electron microscopy. Mixtures of detergent-solubilized lipids and/or proteins were submitted to slow or rapid dilution while measuring the hydrodynamic radii of the aggregates. Lipids alone exhibited lambda-shaped dilution curves with intermediate rod-shaped particles that converted into small vesicles. Depending on the protein-protein and protein-lipid interactions, detergent-solubilized protein-lipid mixtures showed a sharp transition from micelles to large densely packed proteoliposomes. Electron microscopy revealed that formation of crystals occurred shortly after this phase transition.
2D Modeling of Hydraulic Fracture Initiating at a Wellbore with or without Microannulus (2009)

Abstract The goal of this paper is to investigate the near-wellbore phenomena with respect to fracture initiation. The 2D numerical model was developed, which takes into account the interaction of steel casing, cement, and surrounding rock and allows for a curved path of the fracture. The model incorporates an effective finite-difference numerical method for solving a system of coupled differential equations: 1D equations of power law fluid flow along the fracture trajectory and 2D equations of the linear elasticity for rock massif. The model predicts and evaluates the near-wellbore fracture pinching effect as a function of fracture trajectory, perforation misalignment angle, cement/formation properties, stress contrast, and fracturing fluid parameters. The model developed has a limitation: it does not take into account the leakoff and pore pressure changes in near-wellbore zone during fracturing treatment. However, we believe that this limitation is not essential as it does not affect the quality of results obtained and can be eliminated easily. Several different scenarios of fracture initiation and propagation were considered. We modeled the initiation and propagation of the fracture through the narrow channel (microannulus) along cement-rock interface as well as along the misaligned perforation. We also investigated different geometries of microannulus development and made conclusions on the most probable situation for different formation conditions. We conducted the comparative analysis of pressure drops and fracture width reductions for different types of fracture propagation. We also modeled fracture propagation for different perforation phasing angles. Based on the results of numerical experiments, we are able to provide some recommendations on how to avoid the worst case of the fracture initiation scenario.
Autoxidation of Hydrocarbons in the Presence of Boric Acids Decomposition of Aromatic Hydroperoxides (1972)

The autoxidations of aromatic hydrocarbons are inhibited by the addition of boric acids and their derivatives, whereas the oxidations of aliphatic and alicyclic hydrocarbons are not inhibited and give selectively a boric ester of the corresponding secondary alcohol. In order to clarify these facts, tetralyl and cumyl hydroperoxides were decomposed by several types of boric acids and their derivatives. The rates of decompositions of these hydroperoxides were significantly accelerated by the boric acids and their derivatives, and γ-o-hydroxyphenylbutylaldehyde and phenol were produced selectively from tetralyl and cumyl hydroperoxide respectively. It was found that the faster the inhibition of the oxidation of tetralin, the higher the activity of the boric acids and their derivatives in the decomposition of tetralyl hydroperoxide. The acid strength of the boric acids was found to be much larger than that known as Brönsted acids. It was concluded that the boric acids acted as Lewis acids and not as Brönsted acids in the decomposition of aromatic hydroperoxides.
DFT-Spread OFDM MIMO-Radar – An Alternative for Reduced Crest Factors (2019)

Multiple-input multiple-output radar has been recognized as an interesting option for near- to medium-range radar applications, since its virtual antenna array concept offers increased angular resolutions at a compact installation size. Orthogonal frequency-division multiplexing (OFDM) - which is widely employed in wireless communications - has been shown to provide an efficient means to establish the required orthogonal transmit signals. Despite its many advantages, a well-known drawback of OFDM is that transmit signals are typically characterized by relatively high crest factors. This requires corresponding power back-offs at the transmitter side or power amplifiers with highly linear characteristics, so as to avoid undesired signal distortions. In this paper, we propose an alternative OFDM-based waveform adopted from wireless communication systems, which employs a pre-spreading stage by means of a discrete Fourier transform (DFT). By means of computer simulation results, we show that DFT-spread OFDM has similar radar properties as OFDM, while crest factors can be reduced considerably. This renders DFT-spread OFDM a particularly “hardware-friendly” modulation scheme.
The design and analysis of non-uniform down-sized differential distributed amplifiers (2004)

In this paper, the design and analysis of a novel non-uniform fully differential distributed amplifier is presented. The gain-bandwidth product of the proposed amplifier designed in a 0.18 /spl mu/m standard CMOS process reaches a record level of 34.76 GHz. Proved by both the analytical models and the HSPICE simulations, down-sizing the device and inductor sizes of each stage with respect to the preceding stage in a distributed amplifier results in a better gain-bandwidth product. A comprehensive analytical study is carried out to predict the behavior of the amplifier. HSPICE simulations verify the superior performance of the proposed non-uniform distributed amplifier compared to its conventional counterpart in terms of a better gain-bandwidth product and a flat frequency response.
<i>C. elegans</i> ankyrin repeat protein VAB-19 is a component of epidermal attachment structures and is essential for epidermal morphogenesis (2003)

Elongation of the epidermis of the nematode Caenorhabditis elegans involves both actomyosin-mediated changes in lateral epidermal cell shape and body muscle attachment to dorsal and ventral epidermal cells via intermediate-filament/hemidesmosome structures. vab-19 mutants are defective in epidermal elongation and muscle attachment to the epidermis. VAB-19 is a member of a conserved family of ankyrin repeat-containing proteins that includes the human tumor suppressor Kank. In epidermal cells, VAB-19::GFP localizes with components of epidermal attachment structures. In vab-19 mutants, epidermal attachment structures form normally but do not remain localized to muscle-adjacent regions of the epidermis. VAB-19 localization requires function of the transmembrane attachment structure component Myotactin. vab-19 mutants also display aberrant actin organization in the epidermis. Loss of function in the spectrin SMA-1 partly bypasses the requirement for VAB-19 in elongation, suggesting that VAB-19 and SMA-1/spectrin might play antagonistic roles in regulation of the actin cytoskeleton.
BIGH3 mutation spectrum in corneal dystrophies. (2002)

Disease-causing mutations were identified in 80% of the patients (50/61). All mutations localize in two regions of kerato-epithelin: the amino acid R124 and BIGH3 fasc domain 4. This study also confirms the mutation hot spot at positions R124 and R555 with nearly 50% of the mutations targeting these two amino acids (24/50). In addition the corneal phenotypes induced by changes at R124 and R555 are amino acid specific: R124C in CDLI, R555W and R124S in CDGGI, R124H in CDA, R124L in CRRB, and R555Q in CDTB. In CDLIIIA, CDLI/IIIA, and CDL-deep the genotype-phenotype correlation is domain specific, with all changes occurring at the boundary or within the fasc4 domain.
FORMAT CONTROLLING ENCRYPTION USING DATATYPE PRESERVING ENCRYPTION. (2009)

Datatype-Preserving Encryption (DTP) enables encryption of values within a certain character set into ciphertext restricted to the same set, while still keeping data length. This is in contrast to conventional block cipher modes which produce binary data, i e each encrypted character may have an arbitrary value, possibly outside the original character set, often accompanied with a length expansion caused by padding. Format-Controlling Encryption (FCE) is an extension to DTP, for which data length still is kept, but the output character range is allowed to be larger, though not covering the range of all possible values (i e binary data). With FCE it’s possible to handle certain DTP limitations, like limited key rotation and integrity support.
Low-Loss and Wideband Acoustic Delay Lines (2019)

This paper demonstrates low-loss acoustic delay lines (ADLs) based on shear-horizontal waves in thin-film LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> for the first time. Due to its high electromechanical coupling, the shear-horizontal mode is suited for producing devices with large bandwidths. Here, we show that shear-horizontal waves in LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> thin films are also excellent for implementing low-loss ADLs based on unidirectional transducers. The high acoustic reflections and large transducer unidirectionality induced by the mechanical loading of the electrodes on a LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> thin film provide a great tradeoff between delay line insertion loss and bandwidth. The directionality for two different types of unidirectional transducers has been characterized. Delay lines with variations in the key design parameters have been designed, fabricated, and measured. One of our fabricated devices has shown a group delay of 75 ns with an IL below 2 dB over a 3-dB bandwidth of 16 MHz centered at 160 MHz (fractional bandwidth = 10%). The measured insertion loss for other devices with longer delays and different numbers of transducer cells are analyzed, and the loss contributing factors and their possible mitigation are discussed.
