Fast Lookups for In-Memory Column Stores: Group-Key Indices, Lookup and Maintenance. (2012)

In-memory column-oriented databases have become a major topic of interest in academia and commercial applications. The demand for analytics on up-to-the-minute data and the availability of systems with hundreds of gigabytes of main memory led to the proposal of combined systems, which provide a single database for operational processing and adhoc analytical queries on current data. Recent research has identified In-Memory Column-Stores as a possible database architecture to meet these requirements. They are claimed to be capable of delivering the analytical insights while providing sufficient transactional performance. Data therein is typically split up into a write-optimized partition, which gains speed from its small size and tree-structured indices, and a larger read-only partition. To enable fast transactional
Mechanisms of Silicon Dioxide Deposition from the Low Pressure Chemical Vapor Deposition of Diethylsilane/Oxygen Mixtures (1995)

Studies of the gas‐phase products, silicon dioxide film properties, and kinetics of the diethylsilane/oxygen reaction under low pressure chemical vapor deposition (LPCVD), conditions in both packed and unpacked stirred flow reactors are reported. Effects of flow rate, reactant composition, pressure, and various additives (e.g., ethene, helium, toluene, methylchloride, and various peroxides) on the reaction products, product yields, and reaction rates confirm the free radical nature of the reaction and provide mechanistic interpretations for the "cutoff" and "start‐up" problems sometimes encountered in the film deposition process. Additions of free radical source molecules promote the reaction. Thus process temperatures substantially lower than normal (i.e., ) can be used in the LPCVD process without effecting either film quality or film deposition rate. This process temperature lowering was a main study objective. Best results, as judged by film quality and uniformity, were achieved by matching the LPCVD reactor residence time of the reaction mixture to the decomposition lifetime of the promoter. Effective process temperatures were 315°C with added, 270°C with added , and 250°C with added .
Towards the automatic computational assessment of enlarged perivascular spaces on brain magnetic resonance images: A systematic review (2013)

Enlarged perivascular spaces (EPVS), visible in brain MRI, are an important marker of small vessel disease and neuroinflammation. We systematically evaluated the literature up to June 2012 on possible methods for their computational assessment and analyzed confounds with lacunes and small white matter hyperintensities. We found six studies that assessed/identified EPVS computationally by seven different methods, and four studies that described techniques to automatically segment similar structures and are potentially suitable for EPVS segmentation. T2-weighted MRI was the only sequence that identified all EPVS, but FLAIR and T1-weighted images were useful in their differentiation. Inconsistency within the literature regarding their diameter and terminology, and overlap in shape, intensity, location, and size with lacunes, conspires against their differentiation and the accuracy and reproducibility of any computational segmentation technique. The most promising approach will need to combine various MR sequences and consider all these features for accurate EPVS determination.

Endothelialization of PVA/gelatin cryogels for vascular tissue engineering: Effect of disturbed shear stress conditions (2010)

Mechanically, poly(vinyl alcohol) (PVA)-based cryogels are extremely well suited for vascular tissue engineering applications. However, their surface properties lead to a slow rate of endothelialization, and the mode of cell attachment leaves the endothelium susceptible to removal under physiological shear stress conditions. In this study, abrupt and ramped disturbed shear stress conditions created by a turbulent orbital flow were used to examine endothelialization on PVA/gelatin cryogels. Cell proliferation rate and apoptosis were evaluated by fluorescent activated cell sorter (FACS) analysis, and the expression of cell-adhesion molecules was used to evaluate the response of cells on cryogels to static and shear conditions by real-time polymerase chain reaction (RT-PCR). Application of a ramped shear stress had a profound effect on endothelial cell proliferation (22.30 +/- 0.20-fold increase), necrosis (eliminated), apoptosis (1.04 +/- 0.18 increase), and overall facilitation of endothelialization while concomitantly increasing nitric oxide (NO) synthesis levels. Ramped shear stress was also effective in helping the retention of the endothelial cells on the cryogel surface, whereas abrupt application caused widespread removal. Under static conditions, Selectin-P expression decreased, whereas both inter-cellular adhesion molecule (ICAM) and platelet endothelial cell adhesion molecule (PECAM)-I expression increased on cryogels over a 10-day culture period. Under both shear stress conditions, Selectin-P expression was decreased both on cryogels and tissue culture polystyrene (TCPS). Controlled application of disturbed shear stress shortens endothelialization times on cryogel surfaces, in contrast to the established antiproliferative effect of shear stress caused by laminar flow, without compromising their functionality. This demonstrates how such mechanical stimuli can be exploited to alter cellular behavior and facilitate the required outcomes for tissue engineering applications.
EXAMINATION OF THE CAPABILITIES OF ATTACHMENT AND BIOFILM FORMATION OF DIFFERENT Listeria monocytogenes STRAINS (2009)

Listeria monocytogene is the causative agent of a severe illness in humans and animals and food is the main route of infection. Some L. mnocytogenes strains persist on the surface of working areas in food plants for several months or years, so the equipment becomes the source of secondary contamination. Among other things, the persistence is associated with the ability to form a biofilm, alone or in a community with other bacterial species usually present in food industry. Biofilms present long lasting contamination sources, and bacteria in the biofilm express increased resistance to the effect of disinfectants. All materials usually used in food industry, such as stainless steel, aluminum, glass, rubber, fluored polymer, nylon, teflon, may be a substrate for the development of bacterial biofilm. The objective of this work was to examine the capabilities of 14 L. monocytogenes strains of different origin to attach and to form biofilm on glass surface. The strains originated from animals (8 strains), food (4 strains) and feed (1 strain). The referent strain was a human isolate (ATCC 19115). The number of L. monocytogenes was determined after three hours of attachment at 5 o C, 25 o C and 37 o C and after 48-hour incubation in tryptone soy broth by the use of standard count technique on blood agar from tenfold dilution. Three days old biofilm of the selected L. monocytogenes strains was examined by scanning electron microscopy (SEM) and treated with disinfectants (Peral-S and Environ-4) for 5 and 10 minutes. For all the examined L. monocytogenes strains the number of attached bacteria to glass slides for 3 hours of incubation in static conditions at 25 o C and 37 o C ranged from 10 2 -10 4 cfu/cm 2 . After three hours of incubation at 5 o C bacteria did not attach to glass slides. After 48 h of incubation the number of cells that grow on glass slides did not depend on initial attachment and for all the strains it was 10 5 -10 7 cfu/cm 2 . Scanning electron microscopy confirmed the ability of tested strains to attach on glass surface. L. monocytogenes cells attached to glass surface expressed higher resistance to disinfectants that the cells in suspension.

2‘-Chloro-2‘,3‘-dideoxy-3‘-fluoro-<scp>d</scp>-ribonucleosides:  Synthesis, Stereospecificity, Some Chemical Transformations, and Conformational Analysis (2003)

The synthesis of methyl 5-O-benzoyl-2-chloro-2,3-dideoxy-3-fluoro-beta-d-ribofuranoside (5) and its use as a glycosylating agent for persilylated thymine, N(6)-benzoyladenine, and N(4)-benzoylcytosine are described (Scheme 1). The 2'-chloro-2',3'-dideoxy-3'-fluoro-d-ribonucleosides 10-12 synthesized were transformed to 2',3'-dideoxy-3'-fluoro-alpha- and -beta-d-erythro-pentofuranoside nucleosides of thymine (13a,b), adenine (14a,b), and cytidine (15a,b) by treatment with tributyltin hydride in the presence of alpha,alpha'-azobisisobutyronitrile (Scheme 2). Treatment of 2'-chloro-2',3'-dideoxy-3'-fluoro-d-ribonucleosides with 1 M MeONa/MeOH under reflux for 1-5 h afforded 2',3'-didehydro-2',3'-dideoxy-2'-chloro-d-pentofuranosyl nucleosides as the principal products (47-81%) of the reaction, along with recovered starting nucleoside (11-33%) (Scheme 3). Easy HF elimination was also observed in the case of the 2'-azido-2',3'-dideoxy-3'-fluoro-beta-d-ribofuranosides of thymine (17) and adenine (20) (Scheme 3). The role of conformational peculiarities of 2'-chloro-2',3'-dideoxy-3'-fluoro-d-ribonucleosides as well as of 17 and 20 in the observed exclusive elimination of HF is discussed. The conformational analysis of a rather broad palette of 2,3-dideoxy-3-fluoro-2-(X-substituted)-d-ribofuranosides was performed with the aid of the PSEUROT (version 6.3) program, using (i) the recently reparametrized Karplus-type relation (Chattopadhyaya and co-workers. J. Org. Chem. 1998, 63, 4967) and (ii) empirical bond angle correction terms suggested by us. The predictive power of the Brunck and Weinhold model (J. Am. Chem. Soc. 1979, 101, 1700) of the gauche effect between atoms and groups as a conformational driving force acting upon the pentofuranose ring is explored. Their model invokes maximum antiperiplanar sigma <--> sigma stabilization when the donating bond is the least polar one and the acceptor orbital is at the most polarized bond and is found at least as satisfactory, and in various specific cases more so than, as rationalizations on the basis of the preference of the gauche vs the trans conformation of two vicinal electronegative substituents (Wolfe. Acc. Chem. Res. 1972, 5, 102).
Early and Late Heat Shock Proteins in Wheats and Other Cereal Species (1987)

Coleoptiles and roots of 3-day-old seedlings from five cereal species (Triticum aestivum L., T. durum Desf., Hordeum vulgare L., Secale cereale L., and Triticale) respond to heat shock at 40 degrees C by synthesizing a new set of 13 strong bands (as revealed by one-dimensional sodium dodecyl sulfate gel electrophoresis) as well as some 20 degrees C proteins. Heat shock proteins (HSPs) belong to three different size groups: high molecular mass HSPs in the 103 to 70 kilodalton range, intermediate molecular mass HSPs in the 62 to 32 kilodalton range, and low molecular mass HSPs about 17 to 16 kilodalton in size. At the beginning of the heat shock coleoptiles show a reduced ability to synthesize intermediate molecular mass HSPs but after 4 hours at 40 degrees C they exhibit fully developed HSP patterns identical to that found in roots. Synthesis of early HSPs declines after 7 hours of treatment followed by the appearance of a new set of 12 protein bands (late HSPs) in the ranges 99 to 83, 69 to 35, and 15 to 14 kilodaltons. After 12 hours at 40 degrees C, three other late HSPs of 89, 45, and 38 kilodalton are induced. The induction of late HSPs after 7 hours at 40 degrees C appears to be associated with an enhancement of radioactive methionine incorporation into proteins.
On the Permutation Capability of Multistage Interconnection Networks (1987)

We present analytic models for the blocking probability of both unique path and multiple path multistage interconnection networks under the assumption of either permutation or random memory request patterns. The blocking probability of an interconnection network under the assumption of permutation requests is a quantitative measure of the network's permutation capability. We compare the performance of networks with approximately equivalent hardware complexity. It is shown that variations of banyan networks can be designed with extremely low blocking probabilities under the assumption of permutation requests.

Cyclic programmed cell death stimulates hormone signaling and root development in <i>Arabidopsis</i> (2016)

The plant root cap, surrounding the very tip of the growing root, perceives and transmits environmental signals to the inner root tissues. In Arabidopsis thaliana, auxin released by the root cap contributes to the regular spacing of lateral organs along the primary root axis. Here, we show that the periodicity of lateral organ induction is driven by recurrent programmed cell death at the most distal edge of the root cap. We suggest that synchronous bursts of cell death in lateral root cap cells release pulses of auxin to surrounding root tissues, establishing the pattern for lateral root formation. The dynamics of root cap turnover may therefore coordinate primary root growth with root branching in order to optimize the uptake of water and nutrients from the soil.
Diverse G protein and beta-adrenergic receptor mRNA expression in normal and failing porcine hearts (1994)

Right atrial and left ventricular homogenates have similar protein composition and beta-adrenergic receptor (beta-AR) numbers, but the right atrium has > 58% less adenylyl cyclase activity than the left ventricle. Associated with distinctive patterns of adenylyl cyclase activities are differences in G protein regulation between the two chambers. Compared with the left ventricle, the right atrium has 74% less Gs alpha mRNA (P < 0.0001) and 83% less G alpha i-2 mRNA (P < 0.002). When hearts are rapidly paced to produce heart failure, the left ventricle shows significant reductions in mRNA expression for both Gs alpha and G alpha i-2. However, the right atrium shows increased Gs alpha and G alpha i-2 mRNA expression. Despite divergent mRNA expression, Gs alpha and G alpha i-2 protein expression is down-regulated in both chambers in heart failure. In contrast, both chambers have similar beta 1- and beta 2-adrenergic receptor mRNA contents, and there is a selective reduction of beta 1-adrenergic receptor protein and mRNA in response to heart failure. Thus G protein and beta-AR mRNA regulation is regionally diverse in the heart. Physiological and anatomic differences between the right atrium and the left ventricle may dictate distinct patterns of adrenergic signaling and adaptations to stress.

Compassionate communication with parents of children and young people with learning disabilities (2004)

Abstract This paper introduces the concept and practice of compassionate communication as a useful framework for teachers to underpin communicating with parents of children with learning disabilities. Many teachers have had the experience of their language interfering with their intentions around working together, embracing differences and honouring each other's strengths and gifts. Through miscommunication and misunderstanding their well‐intentioned initiatives can go awry. Before any planning for interventions, strategies or accommodations is put in place, it is essential to lay the foundation for a positive relationship between home and school. A literature review will identify the issues within the context of parent‐teacher communication, followed by a discussion of the key elements of compassionate communication. Two case study examples are then considered from the perspective of compassionate communication. Case studies are drawn from the writer's experience supporting school communities through the Learning Difficulties Support Team (LDST), involvement in the Special Needs Parent Helpline, and as a teacher in both private and public sectors and as a parent. I can understand why parents get that angry, because I couldn't get them to see my point of view… I said you are not listening to what I am saying........ I didn't feel like I was getting any help. It was like me and him against the world.’ Parent of a child with a learning disability quoted in Vincent & Martin, 2002, p 118) (The parent) started to ask me ridiculous questions and grill me over the phone about things that were completely unreasonable and wouldn't take no for an answer and it was just crazy. They're just venting on you. And that happens fairly frequently unfortunately. Teacher, quoted in Hargreaves 2001, p. 1065 I've absolutely no idea what I could do to change my approach and reactions. I don't know, I've no ideas left. What can I do? I don't know. Parent of children with a learning disability quoted in Vincent & Martin, 2002, p.118.
Chemolysis of calcium containing urinary calculi. A review. (1994)

A review of current literature and research on chemolysis of calcium containing urinary stones is made. The type of chemolytic solution is dependent upon the composition of the stone. Calcium phosphates can be desolved with Suby or Renadecin solution although it is often tedious and time consuming procedure. Calcium oxalate, the major urinary stone component, can not be dissolved by these solutions. EDTA and other strong calcium chelators cannot be used because of their local toxicity. Certain enzymes can digest the organic matrix of the stone. The indication to chemolysis of stones are rather restricted.
