Charm–anticharm baryon production asymmetries in photon–nucleon interactions (2004)

We report measurements of the charm–anticharm production asymmetries for Λc+, Σc++, Σc0, Σc++∗, Σc0∗, and Λc+(2625) baryons from the Fermilab photoproduction experiment FOCUS (E831). These asymmetries are integrated over the region where the spectrometer has good acceptance. In addition, we have obtained results for the photoproduction asymmetries of the Λc baryons as functions of pL, pT2, and xF. The integrated asymmetry for Λc+ production, (σΛc+−σΛc−)/(σΛc++σΛc−), is 0.111±0.018±0.012, significantly different from zero. The asymmetries of the excited states are consistent with the Λc asymmetry.
Seismic reservoir monitoring on Gullfaks (1997)

Until recently, time-lapse seismic monitoring was considered unproven for tracking the movement of an oil-water contact (OWC). However, Statoil petrophysicists working on sonic logs from the Gullfaks Field in the Norwegian North Sea uncovered changes in log response that were favorable for seismic monitoring. Open hole logs from three wells drilled through the original OWC, compared to logs from wells drilled into water-flushed areas, showed consistently higher velocities in the water-filled zones than in those filled with oil.
Drug sensitivity profiling and molecular characteristics of cells from pleural effusions of patients with lung adenocarcinoma (2015)

We propose to assess the therapeutic value of biomarker-guided individualized chemotherapy in patients with metastasizing lung adenocarcinoma. In this study, we used primary cells from pleural effusions from sixteen patients diagnosed with adenocarcinomas originating in the lung and from four patients with no malignant diagnosis. The ex vivo drug sensitivity of primary cells was assessed for 32 chemotherapeutical drugs. Linear regression analyses were performed to examine possible correlations between the drug sensitivity, overall survival and expression of ERCC1 and RRM1. The ex vivo drug sensitivity profiles of the patients revealed considerable heterogeneity in drug response. Vinblastine, vinorelbine, paclitaxel and actinomycin D showed high efficiency against 50% of the tested primary cells. Significant correlation was detected between the ex vivo sensitivity to platinum based drugs and gemcitabine and the level of ERCC1 and RRM1. No significant correlation was however seen between overall survival and drug sensitivity. The heterogeneity of the drug response suggests that optimal care of the adenocarcinoma patients should include the determination of drug sensitivity of the primary cells and would benefit to use personalized therapy.
Absolute photoluminescence quantum yield enhancement of poly(2-methoxy 5-[2′-ethylhexyloxy]-p-phenylenevinylene) (2006)

A twofold absolute photoluminescence quantum yield (PLQY) enhancement of poly(2-methoxy 5-[2′-ethylhexyloxy]-p-phenylenevinylene) (MEH-PPV) is demonstrated by simple preparation of films where the polymer is blended with the small organic molecule 7,8,10-triphenylfluoranthene (3PF). The photophysical investigation of this particular energy transfer process was carried out using steady state absorption/luminescence spectroscopy and optically detected magnetic resonance techniques. The enhanced PLQY is attributed to direct sensitization of the intrachain emitting state of MEH-PPV by energy transfer from 3PF.
Correction: Transcriptome Analysis Reveals Markers of Aberrantly Activated Innate Immunity in Vitiligo Lesional and Non-Lesional Skin (2013)

Background: Vitiligo is characterized by the death of melanocytes in the skin. This is associated with the presence of T cell infiltrates in the lesional borders. However, at present, there is no detailed and systematic characterization on whether additional cellular or molecular changes are present inside vitiligo lesions. Further, it is unknown if the normal appearing non-lesional skin of vitiligo patients is in fact normal. The purpose of this study is to systematically characterize the molecular and cellular characteristics of the lesional and non-lesional skin of vitiligo patients.
<i>In situ</i> ion channeling study of gallium disorder and gold profiles in Au-implanted GaN (2000)

Disorder accumulation and annealing behavior on the Ga sublattice in gallium nitride (GaN) implanted with 1.0 MeV Au2+ (60° off surface normal) at 180 or 300 K have been studied using in situ Rutherford backscattering spectrometry in a 〈0001〉-channeling geometry. Complete amorphization in GaN is attained at 6.0 and 20 Au2+/nm2 for irradiation at 180 and 300 K, respectively. A saturation in the Ga disorder at and behind the damage peak was observed at intermediate ion fluences at both 180 and 300 K. No measurable thermal recovery was found at 300 K for the full range of damage produced at 180 K. However, distinct epitaxial regrowth in the bulk and Ga reordering at surface occurred after annealing at 870 K. The implanted Au readily diffuses into the highly damaged regions at elevated temperatures, and the redistribution of the Au atoms in the implanted GaN varies with the damage profiles. A double-peak Au profile developed with the maxima located in the amorphous surface region and near the Au mean projected range. The result is interpreted as Au atom diffusion into the amorphous regime near the surface and Au trapping at irradiation-induced defects in the crystal structure. This trapping effect is also evidenced in this study by the suppressed recovery of the Au-decorated disorder in GaN.
The electrochemical behavior of an aluminum alloy anode for rechargeable Al-ion batteries using an AlCl<sub>3</sub>–urea liquid electrolyte (2017)

A novel Al-ion battery based on an Al alloy anode, pyrolytic graphite paper cathode, and low-cost AlCl<sub>3</sub>–urea liquid analogue electrolyte was successfully established. The present Al alloy/PG battery can afford a capacity as high as 105 mA h g<sup>−1</sup>.
LAW Simulant Recipes for Evaluation of Real-Time, In-Line Monitoring Instruments (2020)

Statistically designed recipes were generated for evaluation of in-line instrumentation for the Real-Time In-Line Monitoring (RTIM) program in support of the Hanford Direct-Feed Low Activity Waste (DFLAW) program. The composition matrices were prepared based on Low Activity Waste (LAW) feed vector, melter feed, and Effluent Management Facility (EMF) feed information provided by the flowsheet integration modelling for the DFLAW portion of the Waste Treatment Plant (WTP) mission. These composition matrices were converted to recipes for the LAW feed using the approaches for LAW simulant recipes developed by Savannah River National Laboratory (SRNL). Recipes for the glass forming chemicals (GFCs) were developed based on expected mineral forms to be used to for each element to be added to the recipe. The recipe matrices are shown in the Appendix.

Effect of Adhesion on the Acoustic Functioning of Partial Ossicular Replacement Prostheses in the Cadaveric Human Ear (2006)

The gradual adhesion of a PORP to the promontory produces a consistent reduction in microacoustic transfer to the stapes footplate in the fresh human cadaveric model.
Simulation of a base case for future IGCC concepts with CO2 capture (2009)

The simulation of complex IGCC plants is a useful tool for the evaluation of newtechnologies and the identification of further potential. As part of the HotVeGas project thispaper deals with the modelling of an IGCC plant with CO2 capture using technology believedto be available beyond 2020. The concept developed will be the base case for comparison ofemerging technologies and improved process integration. As simulation tools Aspen Plus isused for the gasification island and gas processing while Ebsilon Professional is applied formodelling the combined cycle.The base design is a dry feed gasifier with full water quench, air side none integrated ASU, 2stage CO conversion, acid gas removal and combined cycle. The main processes aresimulated in detail considering phenomena such as: heat and pressure losses, electrolyticdissociation, none equilibrium, pH and gas solubility. The models are all verified bymanufacture information. The model developed is found to be capable of simulating complexgasification applications. Furthermore, the optimum quench water temperature should be inthe range of 165 textdegreeC. In case of lignite the WTA condensate as alternative quench water sourcereduces efficiency by 0.3
L'integrazione di tecniche geomatiche per l'interpretazione multi-temporale delle variazioni di volume delle superfici di cava (2014)

La geomatica attuale mette a disposizione numerose tecniche che permettono di acquisire informazioni sul territorio, correttamente localizzate nel tempo per una comprensione multi-temporale dei fenomeni dinamici. In particolare, le attività estrattive (coltivazione di cave e miniere) richiedono operazioni di controllo e verifica necessarie per la protezione e la salvaguardia dell'ambiente e del territorio già largamente applicate, a volte in modo non corretto, e spesso senza sfruttare i numerosi dati oggettivi disponibili. Nel presente lavoro verrà mostrato come l'integrazione di differenti tecniche geomatiche possa essere di supporto per decisioni di tipo giuridico quando si debbano, ad esempio, valutare le geometrie e i volumi di cave
Acoustic rhinometry in infants and children. (2000)

Acoustic rhinometry (AR), introduced a decade ago for assessment of the nasal airways of adults, has several attractive features relevant to application in a paediatric population. Its non-invasive nature, simplicity and rapidity are prime assets when examining infants and small children. Valid AR measurements can be obtained in a few seconds and require minimal co-operation. The striking consistency of AR studies of healthy subjects and the agreement with CT-derived and directly measured choanal dimensions are a strong indication of its reliability. Acoustic rhinometry optimised for infants and small children opens new perspectives and possibilities in the assessment of nasal airway dimensions and their relationship to pathological conditions in both the upper and the lower airways. The objective of this paper is to describe the advantages of AR in infants and children, but also point out its limitations and potential sources of error. Practical guidelines as to the measurement procedure and analysis and interpretation of AR-data are outlined.
A molecular image-directed, 3D ultrasound-guided biopsy system for the prostate (2012)

Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. However, this biopsy approach uses two-dimensional (2D) ultrasound images to guide biopsy and can miss up to 30% of prostate cancers. We are developing a molecular image-directed, three-dimensional (3D) ultrasound image-guided biopsy system for improved detection of prostate cancer. The system consists of a 3D mechanical localization system and software workstation for image segmentation, registration, and biopsy planning. In order to plan biopsy in a 3D prostate, we developed an automatic segmentation method based wavelet transform. In order to incorporate PET/CT images into ultrasound-guided biopsy, we developed image registration methods to fuse TRUS and PET/CT images. The segmentation method was tested in ten patients with a DICE overlap ratio of 92.4% ± 1.1 %. The registration method has been tested in phantoms. The biopsy system was tested in prostate phantoms and 3D ultrasound images were acquired from two human patients. We are integrating the system for PET/CT directed, 3D ultrasound-guided, targeted biopsy in human patients.
MATURITY AND REFUNDING EFFECTS ON TREASURY‐BOND FUTURES PRICE VARIANCE (1987)

Abstract Both Samuelson's maturity hypothesis and the Anderson‐Danthine state variable hypothesis are tested in this study of the variance of Treasury‐bond futures prices. Both maturity and the quarterly refunding of Treasury debt have statistically and economically significant effects on futures price variance. The evidence for a monotonic maturity effect is highly statistically significant and robust to changes in model specification. The quarterly refunding is less statistically significant, and it is not clear whether the greatest effect is in the auction week or two weeks thereafter. Economically, these two predictable effects are of greater importance than a change in the discount rate.
ULTRASTRUCTURE AND ELECTRON‐PROBE MICROANALYSIS OF THE METACHROMATIC VACUOLAR GRANULES OCCURRING IN <i>TAXUS</i> MYCORRHIZAS (1981)

SUMMARY Numerous metachromatic vacuolar granules occur in the hyphae of the fungal symbiont of Taxus baccata mycorrhizas. These granules exist in the trunks and in proliferating arbuscules but they are absent in lysed arbuscules. Direct microanalysis with an electron probe shows that they have a high phosphorus and calcium content. Potassium and magnesium are also present but in lesser quantities. The concentration of phosphorus and calcium is higher in the granules than in the light part of the vacuoles. The concentration of phosphorus also is higher in the granules than in the nuclei of the root cells and the concentrations of calcium are greater than those measured in the pecto‐cellulosic wall of root cells. The role of calcium in the metabolism of phosphorus within the tissues of mycorrhizas still remains unknown.
Amorphous InSb and InAs 0.3 Sb 0.7 for long wavelength infrared detection (2011)

The structural, electronic, and optical properties of amorphous InSb and InAs<sub>0.3</sub>Sb<sub>0.7</sub> films deposited on Corning glass, Al<sub>2</sub>O<sub>3</sub> CdZnTe, SiO<sub>2</sub>-Si, and CaF2 substrates by Radio Frequency (RF) magnetron sputtering have been studied as they relate to Mid and Long Wavelength Infrared (MWIR and LWIR) detection. Depositions at elevated substrate temperature and pressure of <10mTorr Ar show an emergence of crystalline grains with strong X-ray diffraction peaks at the (111) and (220) orientations. Electronically the amorphous InSb and InAs<sub>0.3</sub>Sb<sub>0.7</sub> films deposited at 300K show hopping conduction with resistance in InSb ranging from 44 to 1.1E8 Ω-cm at 300K and 84K respectively. Optical analysis using Fourier transform infrared spectroscopy (FTIR) show the absorption of these films has an absorption tail, the equation of which differing activation energies in InSb and InAs0.3Sb0.7. Amorphous InSb and InAs<sub>0.3</sub>Sb<sub>0.7</sub> films showed thermal responsivity in excess of 100V/W for 6μm thick films held at 233K. The maxima and minima of the responsivity are shown to correspond to the interference fringes in the film. The response is highly substrate dependent and compares favorably to other thermal detectors.
A Proposed ''Dredged Material Family of Compaction Curves'' for Field Compaction Control Purposes (2007)

How do we effectively manage the volume of materials generated from the dredging of our waterways near our major coastal cities? A large component of this problem is the available storage volume. The coarse material in dredged material (DM) disposal basins can already be mined for use as fine aggregate due to the depositional processes used in its placement. However, poor quality soils (fines) continue to accumulate in disposal areas and will ultimately result in long term storage capacity issues. Recent work with the U.S. Army Corps of Engineers (USACE)-Philadelphia District has sought ways to utilize these materials in construction. While DM traditionally has been hydraulically placed in disposal basins, its legitimate beneficial use in fill construction is emerging. The successful use of DM in construction will be linked to the reliability of quality control methods associated with DM placement and compaction, DM variability, and knowing the properties of DM and its blends with other media such as crushed curbside-collected glass (CG). In addition to unfamiliarity with DM properties, not being able to respond to DM variability in the field is a major obstacle to its use in mainstream construction. Given the use of "families of curves" for compaction control in standard fill construction, our collaboration with USACE sought to compare scarce DM compaction data to the widely-used Ohio Department of Transportation (ODOT) family of curves. The ODOT curves are often used to allow field technicians to address incoming fill material variations by performing rapid one-point field estimates of the maximum dry density (MDD) to verify lab values or to adjust compaction criteria. This paper proposes modifications to the ODOT curves for use with typical DM and CG-DM blends enabling improved field quality control.
Die Störung des thermischen Gleichgewichtes von schwach ionisierten Caesiumkontaktplasmen durch Wandverluste (1965)

Abstract In einem durch Kontaktionisation hergestellten Caesiumplasma wurde die Plasmadichte mit Langmuir‐Sonden gemessen. Die gemessenen Werte der Plasmadichte liegen weit unter den für thermisches Gleichgewicht nach der Saha‐Gleichung berechneten Werten. Hierfür werden die kalten Teile des Emitters (mechanische Halterungen, Stromzuführungen) verantwortlich gemacht, die mit Caesium bedeckt sind und infolge ihrer geringen Austrittsarbeit als Anoden einen großen Elektronenstrom aufnehmen (Konvertereffekt). Ein Modell, das diesen Trägerverlustmechanismus beschreibt, gibt die Plasmadichte in einigermaßen guter Übereinstimmung mit dem Experiment wieder. Das Elektronengleichgewicht ist auf Grund des Konvertereffektes stark gestört. Im Plasma treten deswegen unter Umständen nicht‐Maxwellsche Elektronenverteilungsfunktionen auf.
Human Platelets Attenuate <i>Aspergillus</i> Species via Granule‐Dependent Mechanisms (2008)

Using laser scanning microscopy, we investigated whether platelets are capable of internalizing Aspergillus conidia and examined Aspergillus-platelet adherence. The influence of platelets on fungal growth was evaluated by assessing galactomannan (GM) release, hyphal elongation, and colony size. A secretion assay with [(3)H]-serotonin (5-hydroxytryptamine [5-HT]) was performed. Exposure to platelets resulted in significantly decreased GM release (p<.05), hyphal elongation (p<.001), colony size, pigmentation, and 5-HT release ( p<.05). A lack of antifungal effects was observed with the microfilament inhibitor cytochalasin D. Platelets attenuate the virulence of Aspergillus species in vitro on the basis of granule-dependent effects.
Clinical Outcome of Fenestrated Fontan Patients After Closure (2000)

Fenestration closure in Fontan patients was followed by improved oxygenation, reduced need for anticongestive medication, and improved somatic growth at latest follow-up. Death (1.3%) or chronic decompensation (3.2%) was rare.
Loss of<i>Drosophila borealin</i>causes polyploidy, delayed apoptosis and abnormal tissue development (2005)

The chromosomal passenger complex (CPC) is a key regulator of mitosis in many organisms, including yeast and mammals. Its components co-localise at the equator of the mitotic spindle and function interdependently to control multiple mitotic events such as assembly and stability of bipolar spindles, and faithful chromosome segregation into daughter cells. Here, we report the first detailed characterisation of a CPC mutation in Drosophila, using a loss-of-function allele of borealin (borr). Like its mammalian counterpart, Borr colocalises with the CPC components Aurora B kinase and Incenp in mitotic Drosophila cells, and is required for their localisation to the mitotic spindle. borr mutant cells show multiple mitotic defects that are consistent with loss of CPC function. These include a drastic reduction of histone H3 phosphorylation at serine 10 (a target of Aurora B kinase), a pronounced attenuation at prometaphase and multipolar spindles. Our evidence suggests that borr mutant cells undergo multiple consecutive abnormal mitoses, producing large cells with giant nuclei and high ploidy that eventually apoptose. The delayed apoptosis of borr mutant cells in the developing wing disc appears to cause non-autonomous repair responses in the neighbouring wild-type epithelium that involve Wingless signalling, which ultimately perturb the tissue architecture of adult flies. Unexpectedly, during late larval development, cells survive loss of borr and develop giant bristles that may reflect their high degree of ploidy.
Tissue‐specific patterns of a maize <i>Myb</i> transcription factor are epigenetically regulated (2001)

The maize p1 gene encodes a Myb-homologous regulator of red pigment biosynthesis. To investigate the tissue-specific regulation of the p1 gene, maize plants were transformed with constructs combining promoter and cDNA sequences of two alleles which differ in pigmentation patterns: P1-wr (white pericarp/red cob) and P1-rr (red pericarp/red cob). Surprisingly, all promoter/cDNA combinations produced transgenic plants with red pericarp and red cob (RR pattern), indicating that the P1-wr promoter and encoded protein can function in pericarp. Some of the RR patterned transgenic plants produced progeny plants with white pericarp and red cob (WR pattern), and this switch in tissue-specificity correlated with increased transgene methylation. A similar inverse correlation between pericarp pigmentation and DNA methylation was observed for certain natural p1 alleles, which have a gene structure characteristic of standard P1-wr alleles, but which confer red pericarp pigmentation and are consistently less methylated than standard P1-wr alleles. Although we cannot rule out the possible existence of tissue-specific regulatory elements within the p1 non-coding sequences or flanking regions, the data from transgenic and natural alleles suggest that the tissue-specific pigmentation pattern characteristic of the P1-wr phenotype is epigenetically controlled.
Global motion cues and the chromatic system (1999)

The capacity of the isolated chromatic system to perceive global motion was tested in a 40-deg visual field by use of random-dot kinematograms. The method of equivalent cone contrasts was used to directly compare the chromatic and the achromatic systems. The minimum number of dots necessary to correctly identify the motion direction was on the order of 20% for the isochromatic conditions, whereas thresholds were rarely obtained in the chromatic conditions. For both the isochromatic and the chromatic conditions, the central visual field was the most sensitive area, whereas the periphery was slightly less sensitive. This study suggests that the chromatic system does not efficiently integrate local motion cues to generate a global motion percept.
