Genomic analysis reveals versatile heterotrophic capacity of a potentially symbiotic sulfur‐oxidizing bacterium in sponge (2014)

Sulfur-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB) play essential roles in marine sponges. However, the detailed characteristics and physiology of the bacteria are largely unknown. Here, we present and analyse the first genome of sponge-associated SOB using a recently developed metagenomic binning strategy. The loss of transposase and virulence-associated genes and the maintenance of the ancient polyphosphate glucokinase gene suggested a stabilized SOB genome that might have coevolved with the ancient host during establishment of their association. Exclusive distribution in sponge, bacterial detoxification for the host (sulfide oxidation) and the enrichment for symbiotic characteristics (genes-encoding ankyrin) in the SOB genome supported the bacterial role as an intercellular symbiont. Despite possessing complete autotrophic sulfur oxidation pathways, the bacterium developed a much more versatile capacity for carbohydrate uptake and metabolism, in comparison with its closest relatives (Thioalkalivibrio) and to other representative autotrophs from the same order (Chromatiales). The ability to perform both autotrophic and heterotrophic metabolism likely results from the unstable supply of reduced sulfur in the sponge and is considered critical for the sponge-SOB consortium. Our study provides insights into SOB of sponge-specific clade with thioautotrophic and versatile heterotrophic metabolism relevant to its roles in the micro-environment of the sponge body.
Modified Entanglement Structure: Model and Comparison with Experiment (1989)

The outline of a model is presented to depict the entanglement states of polymers. Polymer melts are regarded in the model as composed of two components. Free macromolecular chains form the first component and the network of the entangled macromolecular chains the second. The state variables chosen to describe the internal structure of the polymer melt are: two conformational tensors (each describing one component) and another scalar that represents the relative proportion of each component (i.e., related to the entanglement density). The equations governing the time evolution of the state variables and the corresponding formula for the extra stress tensor are suggested with the help of recently developed diffusion‐convection equations. The model provides a convenient framework for the study of changes in the entanglement structure due both to different types of preparation of the polymers and to flow. Rheological data for two types of polyolefins either modified or unmodified are used to make preliminary assessment of the model.
Efficacy of five different formulations of clopyralid on <i>Cirsium arvense</i> (L.) Scop, and <i>Polygonum convolvulus</i> L (1990)

Summary: Experiments were conducted in a controlled environment growth room to compare the phytotoxicity of five formulations of clopyralid and to determine the effect of post‐treatment simulated rainfall applications on the efficacy of these formulations. Clopyralid, formulated as the acid, monoethanolamine salt, potassium salt, 2‐ethylhexyl ester or 1‐decyl ester was applied to Cirsium arvense or Polygonum convolvulus at the 8–10 and 4–6 leaf stage of development, respectively. Based on the shoot and root dry weight data from both species, the 2‐ethylhexyl ester was consistently less phytotoxic than the other four formulations. With respect to Cirsium arvense shoot and root dry weight, there was no difference in efficacy between the acid, monoethanolamine salt, potassium salt and 1‐decyl ester. Root dry weight changes of Polygonum convolvulus did not correlate well with an increase in dose of the five formulations. Maximum increase in stem diameter of Polygonum convolvulus occurred after application of 100 g a.e. ha −1 of the acid, monoethanolamine salt, potassium salt and 1‐decyl ester whereas with the 2‐ethylhexyl ester, the maximum increase occurred after application of 200 g a.e. ha −1 . Simulated rainfall was applied 3, 6, 9 or 12 h after application of 200 g a.e. ha −1 of the five clopyralid formulations to both species. Rainfall reduced the efficacy of clopyralid, regardless of the formulation or species. The 2‐ethylhexyl ester was less efficacious than the other four formulations, irrespective of the timing of simulated rainfall.

Reduced DNA repair capacity in head and neck cancer patients. (1998)

Head and neck cancers (HNCs) are malignancies that can be induced by tobacco use, although host-specific factors such as the DNA repair capacity (DRC) may modulate individual susceptibility to tobacco carcinogenesis. To test the hypothesis that genetically determined DRC modulates HNC susceptibility, we measured the DRC in the peripheral blood lymphocytes of 55 patients with newly diagnosed, previously untreated HNC and 61 healthy controls by the host-cell reactivation assay using a reporter gene damaged by benzo(a)pyrene diol epoxide, an ultimate tobacco-related carcinogen. The mean DRC was significantly lower in cases (8.6%) than it was in controls (12.4%; P < 0.001). The DRC was an independent risk factor for HNC (P < 0.01); those in the middle and lowest tertiles of DRC had increased odds ratios [2.17 (95% confidence interval, 0.74-6.39) and 4.27 (confidence interval, 1.45-12.5), respectively] for HNC. These findings suggest that individuals with reduced DRC may be at increased risk of developing HNC.

Biological Activity of a Furanyl Anti-Juvenile Hormonal Compound on Triatomine Larvae (1996)

Applied topically to larvae of Rhodnius prolixus, Triatoma infestans, Triatoma Vitticeps, Panstrongylus herrera and Panstrongylus megistus a novel, synthetic, furan-containing anti-juvenile hormonal compound, 2-(2-ethoxyethoxy)ethyl furfuryl ether (EEFE) induced a variety of biological responses attributable to an enforced cessation of juvenile hormone secretion, including precocious metamorphosis into diminutive adultoids and retardation of molting. The highest percentage of precocious adultoids was obtained when EEFE was applied prior to feeding. In decreasing order of sensitivity to this anti-juvenile hormone (AJH) were T. infestans, R. prolixus, P. herrera, P. megistus and T. vitticeps. The ED50 of EEFE in R. prolixus compared well with that of the botanically derived AJH, precocene II, but T. infestans was significantly more sensitive to the furanyl antihormone than to precocene II. The significance of these findings is discussed in terms of the complexity of expression of the anti-juvenile hormonal activity during the post-embryonic development of triatomines.

262 Chronic Bowel Perforation Due to Intussusception in an Adult, an Unusual Complication of an Ileocecal Lipoma (2018)

Intussusception is far more common in children than in adults, and the only recorded cases in the literature of bowel perforation associated with intussusception were due to attempted reduction during surgery and were not longstanding perforations. This case describes a 41-year-old active-duty female patient with abdominal pain for 1 year. She described the pain as sharp spasms lasting 1 to 2 hours, once per week. She also stated that she had a food aversion but no vomiting. She had only been able to ingest a liquid diet for two months prior to presentation and had lost 15 pounds in that time. Radiology identified a transverse colon mass on CT. The surgical specimen was described as intussuscepted ascending and transverse colon. An appendix and short length of ileum were also present. Manual reduction of the intussusception proved impossible as the mass was too large (6 cm). The serosal surface had two prominent defects where the inner loop of intussuscepted colon had perforated through the outer loop of colon, exposing mucosa to the abdominal cavity. Surprisingly, these areas were not inflamed grossly or histologically. The mass was lined by intestinal mucosa and attached to the ileocecal valve by a 2 cm stalk. On histology, the mass was a large lipoma. A search of the literature revealed no reported intussusception cases in adults in which the inner loop of intussuscepted colon perforated through the outer loop and exposed mucosa to the abdominal cavity, essentially forming a chronic bowel perforation. We propose that this is the first reported case and want to make physicians aware that this complication can occur with longstanding intussusception, leaving the patient at increased risk of peritonitis.

Can Cold Brew Coffee Be Convenient? A Pilot Study For Caffeine Content in Cold Brew Coffee Concentrate Using High Performance Liquid Chromatography (2017)

Cold brew coffee is a brewing method that is increasing in prevalence. While it has been anecdotally suggested that this method may provide a more aromatic and flavourful coffee product, there is little research published that looks at the concentration of caffeine or other coffee substituents in cold brew coffee. The potential alteration in chemical composition in cold brew provides a few interesting avenues for research. Can caffeine in cold brew be quantified by conventional methods? If so, how does the caffeine profile of cold brews relate to hot brew methods? Here we report the caffeine content and variability in small batch cold brew coffee and show that HPLC/UV-Vis, a standard method for quantitation of caffeine in other extraction methods, is useful for detection of caffeine in cold brew coffee. The mean concentration of caffeine in an average 355 mL serving was found to be 207.22 ± 39.17 mg over five distinct batches of cold brew coffee concentrate. Cold brew preparation methods produce similar quantities of caffeine as hot brew preparation, yet may have increased storage capabilities including improved retention of flavonoids and other secondary metabolites. Therefore, cold brew may provide utility in clinical trials examining caffeine and the effect of other components of coffee as it is commonly consumed.
Myelin formation in dissociated cell cultures of rat embryonic cerebral hemispheres. (1985)

Developing cultures of dissociated cerebral hemispheres obtained from 18-day-old embryonic rats synthesized, or activated, a myelin-related enzyme, 2',3'-cyclic nucleotide 3'-phosphohydrolase (CNPase). This increase in activity coincided with the onset of myelination. The presence of CNPase in oligodendrocytes and myelin was demonstrated using immunocytochemical staining techniques. Myelinated axons and myelin sheaths were clearly made visible by electron microscopy of 28-day-old cultures.
Immunoglobulin VH gene structure and diversity in Heterodontus, a phylogenetically primitive shark. (1985)

A mouse VH probe has been used to identify and isolate VH homologs in a DNA library of Heterodontus francisci (horned shark). The complete nucleotide sequence of one VH gene, HXIA, has been determined and found to exhibit striking organizational homology and nucleotide identity with mammalian prototype VH genes. Metric analysis of the complete sequence is consistent with the early phylogenetic diversification of framework and complementarity-determining regions (CDR). Both the predicted amino acid sequence and the specific hybridization of the CDR2-specific, synthetic oligodeoxynucleotide probe in spleen mRNA suggest that HXIA is functionally expressed. A probe consisting of the entire coding region of this gene hybridizes with multiple components in Southern blot analysis of Heterodontus genomic DNA and together with the identification of additional unique VH+-lambda clones indicates that considerable complexity is associated with the germline VH gene family in a contemporary species that represents an early stage in the phylogenetic development of the vertebrates.
Synthesis and Characterization of Ti<sub>3</sub>(Al<sub>1-n</sub> Ge<sub>n</sub>)C<sub>2</sub> by a Reactive Hot Pressing of TiCx, Al, and Ge Powder Mixture (2007)

Bulk Ti3(Al1-nGen)C2 (n=0, 0.3, 0.5, 0.7, 1.0)were synthesized by a reactive hot pressing of TiCX (x=0.6), Al and Ge powder mixture at 1400 °C for 1 h under 25 MPa. A series of Ti3(Al1-nGen)C2 was successfully synthesised by a hot pressing through a direct liquid-solid reaction between Al-Ge melt and TiCx, and simultaneous densification. Synthesized bulk Ti3(Al1-nGen)C2 was maintained a typical layered structure as shown in other ternary carbide such as Ti3AlC2 and Ti3GeC2. With increasing Al or Ge contents in Ti3(Al1-nGen)C2, both of Vickers hardness and flexural strength of Ti3(Al1-nGen)C2 were increased compared to those of pure Ti3AlC2 and Ti3GeC2 . The maximum flexural strength of Ti3(Al1-nGen)C2 (n=0.3) was about 600 MPa, which was about 3 times higher than that of pure Ti3GeC2. The Vickers hardnesses of Ti3(Al1-nGen)C2 and Ti3AlC2 were slightly decreased with increasing an indentation load.
Large-scale motion of a turbulent boundary layer during relaminarization (1972)

A fully developed turbulent boundary layer was subjected to a strongly favourable pressure gradient in order to investigate the role of the large eddy structure during ‘relaminarization’. Measurements of%he mean velocity profiles indicated that the ‘law of the wall’ disappeared in the region of the maximum pressure gradient. The three fluctuating velocity components and the tangential Reynolds stress were obtained to determine more precisely the nature of the decay of the turbulent structure. These measurements indicated that the absolute level of the velocities and stress were approximately constant along a mean streamline except near the wall. However, the relative levels were decreasing, as reported previously by several authors. The intermittency factor γ decreased along the mean streamlines until most of the boundary layer had only a negligible turbulence level. Space-time auto- and cross-correlations of u, v and I (the intermittency function) of the large-scale structure were obtained in the region of maximum pressure gradient and are compared with those measured in a zero pressure gradient flow.
Transient Radiation Effects in AlGaAs/GaAs MODFETs (1987)

Transient radiation effects were measured in AlGaAs/GaAs MODFETs. The temperature dependence of the long-term transients was measured using 3 ns flash X-ray pulses allowing the observation of trapping levels. These long-term transients were similar to those observed in conventional GaAs FETs, with the exception that persistent photoconductivity was observed in some devices.
PERFORMANCE ANALYSIS OF DECISION SUPPORT WORKLOADS FOR THE DESKTOP ENVIRONMENT (2003)

Database applications are one of the fastest-growing classes of applications. Their execution characteristics differ from those of scientific or general-purpose applications. Due to their proprietary nature, software licenses typically prevent the disclosure of performance information. This has resulted in limited research being carried out in analyzing their performance. Improvements in technology have resulted in increases in processor speed and decreases in cost of main memory and I/O latency. This has resulted in more powerful desktops systems being available at lower prices. In the near future, it is likely that desktop environments may be the choice for small to medium sized database applications. We analyze the performance of Decision Support Systems for the desktop environment. We implement the TPC-H DSS benchmark using the SHORE storage manager on the Windows 2000 platform for this purpose. We find that there is a high amount of sequentiality in the accesses to the database. The file cache performance is very good with copy read hit rates of more than 95 percent. We also find that the performance and scalability of the database depends on the nature of the queries as well as the size and content of the database. Based on our observations, we believe that the desktop environment can support small to medium scale database applications. 1
High efficiency switching using graphene based electron “optics” (2011)

We demonstrate a way to open a gate-tunable transmission gap across graphene p-n junction by introducing an additional barrier in the middle that replaces Klein tunneling with regular tunneling, allowing us to modulate current by several orders of magnitude. The gap arises by angularly sorting electrons by their longitudinal energy and filtering out the hottest, normally incident electrons with the tunnel barrier, and the rest through total internal reflection. Using analytical and atomistic numerical studies, we show that the barrier causes graphene p-n junction act as a metamaterial with metal-insulator transition and overcome the KTln10/decade limit for subthreshold conduction.
Anisotropic conductive paste available for flip chip (2002)

This report aims to explain the applications, concepts, and properties of ACP (anisotropic conductive paste), which was developed for flip chip joining. ACP is a nonsolvent, one-pack-type of liquid connection material. It is composed structurally of fine conductive particles diffused in liquid thermosetting resin. With this paste thermally crimped between two electrodes to provide physical bonding, electrodes that are located opposing or adjacent to each other are provided with conductivity or insulation, respectively. ACP is outstanding in terms of hardening time, requiring only a few seconds at 200/spl deg/C or above, thus assuring high industrial productivity. Also, it is highly stable in long-term storage extending over a few months. Furthermore, the paste's conductivity and insulation properties mean that it can successfully provide flip chip connection with assured reliability. Mounting does not involve the use of lead or flux, and thus the paste is environmentally friendly. ACP is easy to handle and outstanding in terms of productivity, and can thus be recommended as a mounting method with a wide scope for application.
Exploiting Shape Similarity in Engineering Analysis (2006)

Engineering analysis methods, such as the finite element method, are employed extensively to optimize complex engineering designs, but their success in conceptual product development is rather limited since numerous designs must be analyzed to cover the design space, and unfortunately, modern analysis methods can be tedious and time consuming in such scenarios. We propose here a novel analysis methodology for conceptual design wherein, given the simulation results and performance of one of the designs, one predicts upper and lower bounds on the performance of geometrically similar designs. The methodology rests on sound mathematical principles such as adjoint theory of boundary value problems, and is partly motivated by recent work on shape similarity exploitation in manufacturing wherein the cost of manufacturing a new part is estimated by retrieving the manufacturing costs of geometrically similar parts.
