Observation of internal monosaccharide losses in the collisionally activated dissociation mass spectra of anthracycline aminodisaccharides (1998)

The loss of internal monosaccharide residues from anthracycline aminodisaccharides has been studied using high and low energy collisionally activated dissociations (CAD). The mass spectra and low energy CAD spectra obtained using electrospray ionization on a quadrupole mass spectrometer were consistent with a structure in which positions of the two monosaccharide residues were reversed. Key fragment ions observed in the product ion spectra of the peracetylated derivative and the deuterated analog were used to provide evidence that a rearrangement process had occurred. Mass-analyzed ion kinetic energy spectrometry data were also consistent with a rearrangement.
Astrophyllite-alkali amphibole rhyolite, an evidence of early Permian A-type alkaline volcanism in the western Mongolian Altai (2016)

A dyke of alkali rhyolite intrudes the Tsetseg and Zuun Nuruu volcanosedimentary sequence of Ordovician-Silurian age (Hovd Zone, Central Asian Orogenic Belt) at the Botgon bag, Mankhan Soum, Hovd District in Western Mongolia. The rock consists of quartz and K-feldspar phenocrysts set in fine-grained groundmass composed of quartz, K-feldspar, albite, blue alkali amphibole (riebeckite-arfvedsonite containing up to 1.94 wt. % ZrO 2 ), tiny brown radial astrophyllite, annite and accessory zircon, ilmenite, fluorite, monazite, hematite, chevkinite and bastnsite. Astrophyllite has unusual, highly ferroan composition and occurs as two sharply bound zones of astrophyllite I and II with the average empirical formulae: (K 1.71 Na 0.01 Rb 0.08 Cs 0.01 ) (Na 0.93 Ca 0.07 ) (Fe 2+ 6.52 Mn 0.31 Zn 0.06 ) (Ti 0.84 Zr 0.50 Nb 0.55 ) Si 7.68 Al 0.32 O 26 (OH) 3.78 F 0.66 (astrophyllite I, Zr-Nb-rich); (K 1.52 Rb 0.07 ) (Na 0.81 Ca 0.19 ) (Fe 2+ 6.31 Mn 0.28 Zn 0.06 ) (Ti 1.28 Nb 0.30 Zr 0.28 ) Si 7.68 Al 0.32 O 26 (OH) 2.85 F 0.67 (astrophyllite II).
Short communication Accelerometer and rate gyroscope measurement of kinematics: an inexpensive alternative to optical motion analysis systems (2002)

A general-purpose system to obtain the kinematics of gait in the sagittal plane based on body-mounted sensors was developed. It consisted of four uniaxial seismic accelerometers and one rate gyroscope per body segment. Tests were done with 10 young healthy volunteers, walking at five different speeds on a treadmill. In order to study the system’s accuracy, measurements were made with an optic, passive-marker system and the body-mounted system, simultaneously. In all the comparison cases, the curves obtained from the two systems were very close, showing root mean square errors representing o7% full range in 75% of the cases (overall mean 6.64%, standard deviation 4.13%) and high coefficients of multiple correlation in 100% of cases (overall mean 0.9812, standard deviation 0.02). Calibration of the body-mounted system is done against gravity. The body-mounted sensors do not hinder natural movement. The calculation algorithms are computationally demanding and only are applicable off-line. The body-mounted sensors are accurate, inexpensive and portable and allow long-term recordings in clinical, sport and ergonomics settings. r 2002 Elsevier Science Ltd. All rights reserved.
Infection-Promoting Activity of High Molecular Weight Microbial Polysaccharides on Mouse Peritoneal Infections with Pasteurella Pestis (1965)

The virulence of Pasteurella pestis depends on the presence of a number of antigens (Englesberg et al, 1954; Burrows and Bacon, 1956). However, several strains, including P. pestis EV 76, possessing all these antigens are of extremely low virulence. The infectivity of such strains is markedly enhanced by simultaneous injection of iron salts into the site of infection (Jackson and Burrows, 1956). A similar effect has also been obtained by the systemic injection of cortisone (Payne et al, 1955) or high molecular weight microbial neutral and acidic polysaccharides (Shilo, 1963). In the present paper a study of the polysaccharide-enhanced infection of P. pestis EV 76 was undertaken to obtain information on the mechanisms under-
Deformation and Structural Re-formation of Lyotropic Cholesteric Liquid Crystal of Hydroxypropyl Cellulose + Water System (1981)

Abstract Flow properties and optical properties in applying and stopping shear on a lyotropic cholesteric liquid crystalline system of concentrated aqueous solutions of hydroxypropyl cellulose have been studied. The wave length dependence of transmitted light intensity through a sample subjected to steady shear have been measured quantitatively at various shear rates. The spectra of absorbance after the sudden cessation of steady shear flow are also observed as function of time. The shape of the spectrum at a steady state changes very much with shear rate. The shape of spectrum after the sudden cessation of steady shear always recovers quickly. A theoretical model including orientation distribution of Bragg reflection elements is proposed, which is useful to interpret observed spectra-data. Flow situations and also structural formation processes change markedly above and below a certain critical shear rate.

A microtubule depolymerizing kinesin functions during both flagellar disassembly and flagellar assembly in <i>Chlamydomonas</i> (2009)

Cilia and flagella are dynamic organelles that are assembled and disassembled during cell differentiation, during stress, and during the cell cycle. Although intraflagellar transport (IFT) is well documented to be responsible for transport of ciliary/flagellar precursors from the cell body to the flagella, little is known about the molecular mechanisms for mobilizing the cell body-localized precursors to make them available for transport during organelle assembly or for disassembling the microtubule-based axoneme during shortening. Here, we show that Chlamydomonas kinesin-13 (CrKinesin-13), a member of the kinesin-13 family of microtubule depolymerizing kinesins best known for their roles in the cell cycle, functions in flagellar disassembly and flagellar assembly. Activation of a cell to generate new flagella induces rapid phosphorylation of CrKinesin-13, and activation of flagellar shortening induces the immediate transport of CrKinesin-13 via intraflagellar transport from the cell body into the flagella. Cells depleted of CrKinesin-13 by RNAi assemble flagella after cell division but are incapable of the rapid assembly of flagella that normally occurs after flagellar detachment. Furthermore, they are inhibited in flagellar shortening. Thus, CrKinesin-13 is dynamically regulated during flagellar assembly and disassembly in Chlamydomonas and functions in each.
Controlled Growth of Ternary Alloy Nanowires Using Metalorganic Chemical Vapor Deposition (2008)

We report the growth and characterization of ternary AlxGa1- xAs nanowires by metalorganic chemical vapor deposition as a function of temperature and V/III ratio. Transmission electron microscopy and energy dispersive X-ray spectroscopy show that, at high temperatures and high V/III ratios, the nanowires form a core-shell structure with higher Al composition in the nanowire core than in the shell. We develop a growth model that takes into account diffusion of reactants and decomposition rates at the nanowire catalyst and stem to describe the compositional difference and the shell growth rate. Utilizing this model, we have successfully grown compositionally uniform Al0.16Ga0.84As nanowires. The ability to rationally tune the composition of ternary alloy nanowires broadens the application range of nanowires by enabling more complex nanowire heterostructures.
2213 Tooth Contact Analysis of Hypoid Gear of Gleason Method (2006)

Numerical data are calculated and used for CAD/CAM Systems for hypoid gears. New idea for crowning of tooth surface to obtain point contact for hypoid gears is proposed. Tested contact mark on the tooth surfaces of hypoid gear coincide well with the theoretical contact pattern estimated by 3D/CAD drawing and also numerical tooth contact analysis.
Micromachining of laser fusion target parts (1976)

A 5W argon ion laser that operates CW is used. A broad band rear mirror is tuned to maximum power output. The beam is directed vertically by an adjustable turning prism, through a beam splitter, and then focused with an ordinary microscope objective lens onto the material to be cut. The beam splitter allows a telescope and television camera arranged to view the cutting through the same lens that is focusing the laser. The object to be cut is mounted on a micromanipulator which can move the object in two dimensions in the focal plane of the laser. (MOW)

Hydrostatic Pressurization and Depletion of Trapped Lubricant Pool During Creep and Sliding Contact of a Rippled Indenter Against a Biphasic Articular Cartilage Layer (2000)

Abstract This study presents an analysis of the contact of a rippled rigid impermeable indenter against a cartilage layer, which represents a first simulation of the contact of rough cartilage surfaces with lubricant entrapment. Cartilage was modeled with the biphasic theory for hydrated soft tissues, to account for fluid flow into or out of the lubricant pool. The findings of this study demonstrate that under contact creep, the trapped lubricant pool gets depleted within a time period on the order of seconds as a result of lubricant flow into the articular cartilage, while for steady state sliding contact a lubricant pool cannot be sustained. These results suggest that the classical cartilage lubrication models of weeping and boosted lubrication may have to be revised. More recent mixture-based models described in the literature are able to predict the frictional response of articular cartilage without necessarily assuming or requiring entrapment of lubricant pools at the articular contact interface.
Robust interfaces for mixed-timing systems with application to latency-insensitive protocols (2001)

This paper presents several low-latency mixed-timing FIFO designs that interface systems on a chip working at different speeds. The connected systems can be either synchronous or asynchronous. The design are then adapted to work between systems with very long interconnection delays, by migrating a single-clock solution by Carloni et al. (for “latency-insensitive” protocols) to mixed-timing domains. The new designs can be made arbitrarily robust with regard to metastability and interface operating speeds. Initial simulations for both latency and throughput are promising.
Truss Performance and Packaging Metrics (2006)

In the present paper a set of performance metrics are derived from first principals to assess the efficiency of competing space truss structural concepts in terms of mass, stiffness, and strength, for designs that are constrained by packaging. The use of these performance metrics provides unique insight into the primary drivers for lowering structural mass and packaging volume as well as enabling quantitative concept performance evaluation and comparison. To demonstrate the use of these performance metrics, data for existing structural concepts are plotted and discussed. Structural performance data is presented for various mechanical deployable concepts, for erectable structures, and for rigidizable structures.

Galois field hardware architectures for network coding (2010)

This paper presents and analyzes novel hardware designs for high-speed network coding. Our designs provide efficient methods to perform Galois field (GF) dot products and matrix inversions, which are important operations in network coding. Encoder designs that perform GF dot products and vary with respect to the number of messages combined, Galois field size, and input message size are implemented and analyzed to evaluate design tradeoffs. We investigate single cycle, multicycle, and pipelined designs with and without feedback mechanisms for encoding multiple sets of messages. The decoder is implemented as a multi-cycle design and performs GF matrix inversion followed by multiple GF dot products. Our designs are synthesized with a 65nm standard cell library and compared in terms of area, critical path delay, and throughput. Designs combining four messages achieve throughputs of more than 30 Gbps. Our designs can scale to achieve much higher throughput through the use of additional hardware.
Crystal Engineered Acid−Base Complexes with 2D and 3D Hydrogen Bonding Systems Using a Bisphosphonic Acid as the Building Block (2004)

The phosphonic acid iminobis(methylene phosphonic acid), NDP, [NH2(CH2PO3H)2][H3O], exists as a zwitterion and can act as both a hydrogen bond donor and acceptor. NDP synthon was reacted with three organic bases, 2,2‘-bipyridine, 4,4‘-trimethylene-dipyridine, and a hexaazamacrocyclic crown ether, to construct highly stable hydrogen bonded structures. The 2,2‘-bipyridine complex 2 is layered, the layers being formed through hydrogen bonding of the phosphonic acid groups. The layers are largely formed by strong PO−H···-O−P type hydrogen bonds (2.49−2.62 Å) with the protonated bipyridyls held between the layers by strong NH+···O−P hydrogen bonds. In complex 3, each amino-nitrogen atom is protonated leaving each phosphonic acid group negatively charged. The NDP molecules align in hydrogen bonded rows in which the molecules are bonded together by quadruple hydrogen bonds: two P−O-···HO−P and two NH2+···O−P. The rows are then connected to each other by the NH2+···O−P hydrogen bonds between the pyridyl and the phosphonic acid groups. In compound 4, the azacrown ether ring encloses two NDP molecules with four such entities arranged in the unit cell according to the P21/n symmetry. There are 14 water molecules per ring filling the voids between the rings creating a three-dimensional hydrogen bonding network.
Combustion of methane over palladium based catalysts - A study of catalytic deactivation a the use of electrochemical oxygen pumping (2007)

Methane oxidation over palladium is of interest due to its clean catalytic combustion properties, forming only carbon dioxide and water. A successful palladium based catalyst will virtually eliminate polluting by products including unburned hydrocarbons, carbon monoxide, soot, and NOx. These potential benefits have have not been realized, in part due to catalyst deactivation over time. In this study we identify a relationship between catalyst deactivation and hydroxyl formation on Pd/Al2O3 and Pd/TiO2 catalyst surfaces, using time series FTIR spectroscopy. FTIR analysis suggests that catalyst deactivation is caused by growth of surface hydroxyls at temperatures below 450°C, and that that oxygen mobility on the catalyst surface may correlate with the degree of catalytic deactivation. We also examine the use of electrochemical oxygen pumping through a yttrium stabilized zirconia (YSZ) membrane as a possible method of delivering oxygen to the methane catalytic combustion reaction and improving catalytic conversion. We observe that applying a potential across a YSZ membrane can result in moderate increases in methane conversion, and that oxygen concentration in reactant gas mixture has a dramatic effect on catalytic activity. Our study will also address electrochemical oxygen transport to determine its rate limiting impact on the methane catalytic combustion reaction.
Major Lower Extremity Lawn Mower Injuries in Children (1995)

Between 1983 and 1993, 16 children with 18 lower extremity power lawn mower-related injuries were treated at Children's Hospital of Philadelphia. Eleven of 16 patients (69%) were bystanders or nonoperators. The average age at injury was 4 years 9 months. Length of follow-up averaged 3 years 10 months. There was an average of 4.9 procedures per patient. Fourteen of the 18 limbs injured required eventual amputation (78%). We propose a new classification of lawn mower injuries in children. The most common injury (16 of 18 limbs) was a shredding type injury and was either intercalary or distal. The second was a paucilaceration type (two of 18 limbs). Of the four salvaged limbs, there were two shredding type injuries, and on most recent follow-up are considered to have poor results. The two patients with the paucilaceration type injuries and limb salvage are considered to have excellent results. All patients with a shredding type injury ultimately required amputation or had poor results with the salvaged limb. Limb salvage surgery was associated with prolonged hospitalizations, a higher incidence of surgical problems, a longer treatment course, and more complications than early ablative procedures.
Modality Specific Meta Features for Authorship Attribution in Web Forum Posts (2011)

This paper presents a new method for Authorship Attribution (AA) on online forum posts. The idea behind the method is to generate meta features that capture modality specific similarity relations among texts from different authors. Each modality represents a particular linguistic dimension (syntactic, lexical, stylistic). To evaluate this approach we measure prediction accuracy on data from an online forum with up to 100 candidate authors. We also compare our results with a state of the art approach that has shown to perform well across different genres. We have found the meta features to be especially helpful in the online forum domain, where the documents are very short, showing this to be a very promising direction for AA on a realistic web forum scenario. 1

Impact of Spectroscopic Line Parameters on Carbon Monoxide Column Density Retrievals from Shortwave Infrared Nadir Observations (2015)

Among the various input data required for retrieval of atmospheric state parameters from infrared remote sensing observations molecular spectroscopy line data have a central role, because the data quality is critical for the quality of the retrieval product.\nHere we discuss the impact of the line parameters on vertical column densities (VCD) estimated from short wave infrared nadir observations.\nUsing BIRRA (the Beer InfraRed Retrieval Algorithm) comprising a line-by-line radiative transfer code (forward model) and a separable nonlinear least squares solver for inversion we retrieve carbon monoxide from observations of SCIAMACHY aboard Envisat.\nRetrievals using the recent versions of HITRAN und GEISA have been performed and the results are compared in terms of residual norms, molecular density scaling factors, their corresponding errors, and the final VCD product.\nThe retrievals turn out to be quite similar for all three databases, so a definite recommendation in favor of one of these databases is difficult for the considered spectral range around 2.3mue.\nNevertheless, HITRAN 2012 appears to be advantageous when evaluating the different quality criteria.
Aldehyde-Alcohol Reactions Catalyzed under Mild Conditions by Chromium(III) Terephthalate Metal Organic Framework (MIL-101) and Phosphotungstic Acid Composites (2011)

Porous materials based on chromium(III) terephthalate metal organic frameworks (MIL-101) and their composites with phosphotungstic acid (PTA) were studied as heterogeneous acid catalysts in aldehyde-alcohol reactions exemplified by acetaldehyde-phenol (A-P) condensation and dimethylacetal formation from benzaldehyde and methanol (B-M reaction). The MIL-101 was synthesized solvothermically in water, and the MIL101/PTA composite materials were obtained by either impregnation of the already prepared MIL-101 porous matrix with phosphotungstic acid solution or by solvothermic treatment of aqueous mixtures of Cr(NO(3))(3), and terephthalic and phosphotungstic acids. The MIL101/PTA materials appeared to be effective catalysts for both A-P and B-M reactions occurring at room temperature, with half-lives ranging from 0.5 h (A-P) to 1.5-2 h (B-M) and turnover numbers over 600 for A-P and over 2900 for the B-M reaction, respectively. A synergistic effect of the strong acidic moieties (PTA) addition to mildly acidic Brønsted and Lewis acid cites of the MIL-101 was observed with the MIL101/PTA composites. The ability of the PTA and MIL101/PTA materials to strongly absorb and condense acetaldehyde vapors was discovered, with the MIL101/PTA absorbing over 10-fold its dry weight of acetaldehyde condensate at room temperature. The acetaldehyde was converted rapidly to crotonaldehyde and higher-molecular-weight compounds while in contact with MIL-101 and MIL101/PTA materials. The stability of the MIL-101 and MIL101/PTA catalysts was assessed within four cycles of the 1-day alcohol-aldehyde reactions in terms of the overall catalyst recovery, PTA or Cr content, and reaction rate constants in each cycle. The loss of the catalyst over 4 cycles was approximately 10 wt % for all tested catalysts due to the incomplete recovery and minute dissolution of the components. The reaction rates in all cycles remained unchanged and the catalyst losses stopped after the third cycle. The developed MIL101/PTA composites appear to be feasible for industrial catalytic applications.
Predicting replicated database scalability from standalone database profiling (2009)

This paper develops analytical models to predict through-put and response time of a replicated database using meas-urements of the workload on a standalone database. These models allow workload scalability to be estimated before the replicated system is deployed, making the technique useful for capacity planning and dynamic service provi-sioning. The models capture the scalability limits stemming from update propagation and aborts for both multi-master and single-master replicated databases that support snap-shot isolation.
