Field experimental data for crop modeling of wheat growth response to nitrogen fertilizer, elevated CO2, water stress, and high temperature (2018)

Field experimental data of five experiments covering a wide range of growing conditions are assembled for wheat growth and cropping systems modeling. The data include an experiment on interactive effects of elevated CO2 by water and elevated CO2 by nitrogen fertilizer application from a Free-Air Carbon Dioxide Enrichment experiment (FACE) at Arizona in USA; a nitrogen rate fertilizer experiment from three locations and two years in The Netherlands; water deficit experiments at Lincoln in New Zealand and at Cunderdin in Australia; and a temperature sensitivity experiment at Obregon in Mexico. The data consist of 65 experimental treatments with more than 1000 detailed observations, with time series of development and growth, soil water and soil nitrogen dynamics, yield and yield components, daily weather, soil characteristics, and cultivar descriptions. These data have been used in various previous agronomic and crop modeling studies. Assembled data are quality checked and supplied in Agricultural Model Inter-comparison and Improvement (AgMIP) format. Data access via DOI 10.7910/DVN/V4P6PU.

Effect of processing conditions and reactive compatibilizer on the morphology of injection molded modified poly(phenylene oxide)/polyamide‐6 blends (2000)

Abstract The effect of injection molding conditions and reactive compatibilization on the morphology of maleic anhydryde‐modified poly(phenylene oxide)/polyamide‐6 blends was investigated. The injection flow rate primarily influenced the position of the subskin layer, and the injection temperature affected the aspect ratio of the dispersed phase. A reduction of the sue of the dispersed phase occured during the converging flow in the barrel‐to‐sprue zone. The reactive compatibilization reduced the flow induced deformation, the coalescence and the breakup of particles and improved the dispersion of the minor phase.
Nonlinear transmission and color-center dynamics in germanosilicate fibers at 420–540 nm (1988)

We report evidence in support of the view that induced loss and nonlinear transmission in pure germanosilicate fibers at blue-green wavelengths are governed by the formation (through two-photon absorption), spontaneous and stimulated transformation, and bleaching (through single-photon events) of Ge(1), Ge(2), and Ge(3) color centers. Using a tunable pulsed-dye laser, the excitation spectrum of the induced absorption, its spectral attenuation, and the effects of Ge concentration and thermal annealing are investigated.
An optical polarimetric imaging system for surface defect detection of aircraft engines (2003)

The design of an optical polarimetric imaging system, aimed to detect cracks or structural defects on the surface of rotating aircraft engine shafts, is presented. The experimental results clearly indicate that high signal-to-noise ratio signals can be obtained, without further data processing.
Silicon multi-branch nanostructures for decent field emission and excellent electrical transport (2011)

We report on the synthesis, field electron emission and electric transport properties of a novel nanomaterial: ordered arrays of crystallized silicon multi-branch nanostructures. A decent field electron emission with relatively low turn-on field of 3.16 V microm(-)(1) and high field-enhancement factor of 1252 was received for the silicon nanobranches. The relevancies between field-emission current-voltage characteristic, turn-on field, threshold field and sample-anode distance have been thoroughly analyzed. In addition, electrical transport measurements revealed a small electrical resistance of 0.51 MOmega for as-prepared silicon nanobranches. In contrast, by improving the silicon nanobranch-electrode contact, vacuum annealing dramatically reduced the electrical resistance, by a factor approaching two, while thermal oxidation resulted in a much higher resistance due to the amorphous oxide coating of the silicon nanobranches, both of the current versus voltage curves became more linear and symmetrical, and the transport stability was obviously improved.
SPOTTED FEVER GROUP RICKETTSIAE IN TICKS FROM THE MASAI MARA REGION OF KENYA (2003)

We have identified for the first time Rickettsia africae, and the ticks that harbored them, in Kenya. A total of 5,325 ticks were collected from vegetation, livestock, and wild animals during two field trips to southwestern Kenya. Most were immature forms (85.2%) belonging to the genera Amblyomma or Rhipicephalus. The adults also included representatives from the genus Boophilus. Ticks were assessed for rickettsial DNA by a polymerase chain reaction (PCR) using primers for the spotted fever group (SFG)-specific rickettsial outer membrane protein A (rompA) gene, and positive amplicons were sequenced. While none of the immature ticks tested positive by PCR, 15.8% of the adult Amblyomma variegatum and less than 1% of the Rhipicephalus spp. were SFG positive. Sequences of amplified products were identified as R. africae. These findings extend the known range of R. africae.

VO/sub 2/ thin films. Interim report, August 1985-July 1986 (1986)

Amorphous films of vanadium dioxide were prepared by the thermal decomposition of vanadium acetylacetonate in a CO/CO/sub 2/ atmosphere. Films were deposited on glass and quartz.
Synthesis of Phenanthrenes and Polycyclic Heteroarenes by Transition‐Metal Catalyzed Cycloisomerization Reactions (2004)

Readily available biphenyl derivatives containing an alkyne unit at one of their ortho-positions are converted into substituted phenanthrenes on exposure to catalytic amounts of either PtCl2, AuCl, AuCl3, GaCl3 or InCl3 in toluene. This 6-endo-dig cyclization likely proceeds through initial pi-complexation of the alkyne unit followed by interception of the resulting eta2-metal species by the adjacent arene ring. The reaction is inherently modular, allowing for substantial structural variations and for the incorporation of substituents at any site of the phenanthrene product. Moreover, it is readily extended to the heterocyclic series as exemplified by the preparation of benzoindoles, benzocarbazoles, naphthothiophenes, as well as bridgehead nitrogen heterocycles such as pyrrolo[1,2-a]quinolines. Depending on the chosen catalyst, biaryls bearing halo-alkyne units can either be converted into the corresponding 10-halo-phenanthrenes or into the isomeric 9-halo-phenanthrenes; in the latter case, the concomitant 1,2-halide shift is best explained by assuming a metal vinylidene species as the reactive intermediate. The scope of this novel method for the preparation of polycyclic arenes is illustrated by the total synthesis of a series of polyoxygenated phenanthrenes that are close relatives of the anticancer agent combretastatin A-4, as well as by the total synthesis of the aporphine alkaloid O-methyl-dehydroisopiline and its naturally occurring symmetrical dimer.
Growth Promoting and Inhibitory Activities Of 3T3 and Other Cell Lines for Thiol-dependent Lymphoma Cells in Vitro (1978)

SummaryThe growth of thiol dependent cells of Lymphoma L1210(V) is supported by 3T3 and L cells as well as by macrophages in vitro. The supporting cells do not permanently condition the medium, but diffusion chamber studies show that growth promotion is mediated humorally. At high cell density inhibition of lymphoma cell growth can be observed in the supernatant from one of the 3T3 sublines examined, which appears to be due to a nondialyzable inhibitor whose effect is unrelated to thiol dependency.

LEOPARD: a Logical Effort-based fanout OPtimizer for ARea and Delay (1999)

We present LEOPARD, a fanout optimization algorithm based on the effort delay model for near-continuous size buffer libraries. Our algorithm minimizes area under required timing and input capacitance constraints by finding the tree topology and assigning different gains to each buffer to minimize the total buffer area. Experimental results show that the new algorithm achieves significant buffer area improvement compared to previous approaches.
<i>Mycoplasma hominis</i> periaortic abscess following heart–lung transplantation (2017)

We report the first case of Mycoplasma hominis periaortic abscess after heart-lung transplantation. The absence of sternal wound infection delayed the diagnosis, but the patient successfully recovered with debridement surgeries and long-term antibiotic therapy. Owing to the difficulty in detection and the intrinsic resistance to beta-lactams, M. hominis infections are prone to being misdiagnosed and undertreated. M. hominis should be suspected in cases where conventional microbiological identification and treatment approaches fail.
Direct Observation of Flocculation/Coalescence of Metastable Oil Droplets in Surfactant-free Oil/Water Emulsion by Freeze-Fracture Electron Microscopy (2000)

Direct imaging of flocculation/coalescence in surfactant-free oil/water emulsion was achieved by freeze-fracture electron microscopy (FFEM) on benzene oil droplets ultrasonically dispersed in water. Immediately after sonication, spherical droplets with diameters at 30−100 nm (S class) and aggregates consisting of S class droplets at 200−500 nm (M class) were observed. An hour later, we were able to obtain FFEM images, in which a number of S class droplets in flocculation coalesced into larger droplets. Additionally, two droplets of M class coalesced easily when these droplets were in contact with each other. These results support that M and L (≥1000 nm) class droplets are formed through flocculation of S class droplets and coalescence of M class droplets, respectively.

An Ocean in Common: American Naval Officers, Scientists, and the Ocean Environment (review) (2003)

In the late 1980s, while working as an engineer at the Woods Hole Oceanographic Institution, I spent many a late night alone in the lab. Occasionally an older gentleman would come around the darkened building and ask me what I was working on. He'd listen with genuine interest, contribute a few insights, and then regale me with miniature lectures about far-out ideas, like hanging long cables from geosynchronous satellites. It all sounded a bit nutty, but the man had been right before. He was Allyn Vine, and I knew he was the father of Woods Hole's famous three-person submersible, Alvin, which was named after him. I also had a vague sense that he'd had a longer history in oceanography, but only by gathering snippets from the local culture.

Cytochrome <i>c</i> in the apoptotic and antioxidant cascades (1998)

Recent progress in studies on apoptosis has revealed that cytochrome c is a pro-apoptotic factor. It is released from its places on the outer surface of the inner mitochondrial membrane at early steps of apoptosis and, combining with some cytosolic proteins, activates conversion of the latent apoptosis-promoting protease pro-caspase-9 to its active form. Cytochrome c release can be initiated by the pro-apoptotic protein Bax. This process is blocked by the anti-apoptotic proteins Bcl-2 and Bcl-xL. The role of cytochrome c in apoptosis may be understood within the framework of the concept assuming that the evolutionary primary function of apoptosis was to purify tissues from ROS-overproducing cells. In this context, the pro-apoptosis activity of cytochrome c might represent one of the anti-oxidant functions inherent in this cytochrome. Among other cytochrome c-linked antioxidant mechanisms, the following systems can be indicated. (1) Cytochrome c released from the inner mitochondrial membrane to the intermembrane space can operate as an enzyme oxidizing O2.- back to O2. The reduced cytochrome c is oxidized by cytochrome oxidase (or in yeasts and bacteria, by cytochrome c peroxidase). (2) The intermembrane cytochrome c can activate the electron transport chain in the outer mitochondrial membrane. This bypasses the initial and middle parts of the main respiratory chain, which produce, as a rule, the major portion of ROS in the cell. (3) The main respiratory chain losing its cytochrome c is inhibited in such a fashion that antimycin-like agents fail to stimulate ROS production.
Integration of problem-solving and learning in intelligent robots (1992)

In the real world, there are many kinds of uncertainties in the motions of robots. Moreover, robots cannot always get sufficient knowledge about tasks in advance. Intelligent robots therefore have to possess both problem-solving ability, to decide on the proper motions with insufficient knowledge, and learning ability, to acquire knowledge from experiences. Effective integration of these two kinds of ability is also important. In this paper, we describe an experimental system named ARPEX-L (Automatic Robot Planning and Execution System with Learning Ability). ARPEX-L consists of the integration of reactive planning and learning. We applied ARPEX-L to two kinds of robot task: a pick-and-place task and a pushing block task. The former is a simple example of automatic robot programming. The latter is an attempt to make an actual robot learn by a symbolic framework. These applications show the validity of our approach in constructing intelligent robot systems. Current defects of the system and future work are also described.

Detection of early-stage Alzheimer’s pathology using blood-based autoantibody biomarkers in elderly hip fracture repair patients (2019)

Post-operative delirium (POD) is the most common complication following major surgery in non-demented older (>65 y/o) patients. Patients experiencing POD show increased risk for future cognitive decline, including mild cognitive impairment (MCI) and Alzheimer's disease (AD) and, conversely, patients with cognitive decline at surgery show increased risk for POD. Here, we demonstrate that a previously established panel of AD-driven MCI (ADMCI) autoantibody (aAB) biomarkers can be used to detect prodromal AD pre-surgically in individuals admitted into the hospital for hip fracture repair (HFR) surgery. Plasma from 39 STRIDE (STRIDE: A Strategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients) HFR patients and sera from 25 age- and sex-matched non-demented and non-surgical controls were screened using human protein microarrays to measure expression of a panel of 44 previously identified MCI aAB biomarkers. The predictive classification accuracy of the aAB biomarker panel was evaluated using Random Forest (RF). The ADMCI aAB biomarkers successfully distinguished 21 STRIDE HFR patients (CDR = 0.5) from 25 matched non-surgical controls with an overall accuracy of 91.3% (sensitivity = 95.2%; specificity = 88.0%). The ADMCI aAB panel also correctly identified six patients with preoperative CDR = 0 who later converted to CDR = 0.5 or >1 at one-year follow-up. Lastly, the majority of cognitively normal (CDR = 0) STRIDE HFR subjects that were positive for CSF AD biomarkers based on the A/T/N classification system were likewise classified as ADMCI aAB-positive using the biomarker panel. Results suggest that pre-surgical detection of ADMCI aAB biomarkers can readily identify HFR patients with likely early-stage AD pathology using pre-surgery blood samples, opening up the potential for early, blood-based AD detection and improvements in peri- and postoperative patient management.

Normetanephrine Excretion and Affective State in Depressed Patients Treated with Imipramine (1966)

Urinary excretion of normetanephrine, the metabolite of norepinephrine which may reflect noradrenergic activity, showed a gradual increase during the period of definitive clinical improvement in depressed patients treated with imipramine. These and other findings of the study suggest that noradrenergic activity may gradually increase during clinical improvement from depression, and that noradrenergic activity may be relatively decreased in retarded depression and increased in mania. The pharmacological action of imipramine may initiate increases in noradrenergic activity and clinical improvement, in depressed patients, that are subsequently maintained after discontinuation of the drug.
Comparison of global and local sensitivity techniques for rate constants determined using complex reaction mechanisms (2001)

Abstract Many rate constant measurements, including some “direct” measurements, involve fitting a complex reaction mechanism to experimental data. Two techniques for estimating the error in such measurements were compared. In the first technique, local first‐order elementary sensitivities were used to rapidly estimate the sensitivity of the fitted rate constants to the remaining mechanism parameters. Our group and others have used this technique for error estimation and experimental design. However, the nonlinearity and strong coupling found in reaction mechanisms make verification against globally valid results desirable. Here, the local results were compared with analogous importance‐sampled Monte Carlo calculations in which the parameter values were distributed according to their uncertainties. Two of our published rate measurements were examined. The local uncertainty estimates were compared with Monte Carlo confidence intervals. The local sensitivity coefficients were compared with coefficients from first and second‐degree polynomial regressions over the whole parameter space. The first‐order uncertainty estimates were found to be sufficiently accurate for experimental design, but were subject to error in the presence of higher order sensitivities. In addition, global uncertainty estimates were found to narrow when the quality of the fit was used to weight the randomly distributed points. For final results, the global technique was found to provide efficient, accurate values without the assumptions inherent in the local analysis. The rigorous error estimates derived in this way were used to address literature criticism of one of the studies discussed here. Given its efficiency and the variety of problems it can detect, the global technique could also be used to check local results during the experimental design phase. The global routine, coded using SENKIN, can easily be extended to different types of data, and therefore can serve as a valuable tool for assessing error in rate constants determined using complex mechanisms. © 2001 John Wiley & Sons, Inc.

Rapid measurement of monod half‐velocity coefficients for bacterial kinetics (1975)

Abstract The common methods for measuring Monod half‐velocity coefficients are reviewed. All methods have serious disadvantages for obtaining rapid and accurate measurements whether batch‐fed or continuous‐fed systems are used. An “infinite dilution” technique is described that overcomes these difficulties. Data obtained by this method for autotrophic oxidation of NO 2 − and NH 4 + gave 20°C, pH 7.0, K 3 values of 0.07 mg NO 2 −‐N/liter and 0.50 mg NH 4 ±N/liter, respectively.
Molecular Recognition Abilities of a New Class of Water-Soluble Cyclophanes Capable of Encompassing a Neutral Cavity (1999)

We developed a new class of water-soluble cyclophanes, pyrenophanes, capable of encompassing a neutral cavity, in which the hydrophobic area is constructed by aligning two flat polynuclear aromatic rings parallel at an appropriate space that could interpose just one layer of aromatic plane. The height, depth, and width of the cavity in an open conformation of the pyrenophane are 0.46, 0.95, and 1.31 nm, respectively, i.e., the area of this cavity is so large that even porphirin compounds might be incorporated. In the fluorescence spectra, the pyrenophanes showed only excimer-emission, reflecting the existence of two proximal pyrene rings. Treatment of the pyrenophanes with anionic and cationic aromatic compounds revealed the formation of complexes in the UV and fluorescence spectra, suggesting that the binding affinities of the pyrenophanes for aromatic compounds were mainly governed by hydrophobic and/or π-stacking interactions. The macrocyclic structures of the pyrenophanes were found to be indispensable for the complexation.
