Pure bending dynamics in the acetylene X 1Σg+ state up to 15 000 cm−1 of internal energy (1998)

We investigate the large-amplitude bending dynamics of acetylene, in its ground electronic state, using an effective Hamiltonian model that reproduces all relevant experimental data, up to 15 000 cm−1 in internal energy, with 1.4 cm−1 accuracy (1σ). The experimental data which make this analysis possible are derived from the dispersed fluorescence (DF) data set that we recently reported [J. P. O’Brien et al., J. Chem. Phys. 108, 7100 (1998)] for the acetylene Ã 1Au→X̃ 1Σg+ system, which includes DF spectra recorded from five different vibrational levels of the Ã 1Au state. A numerical pattern recognition technique has permitted the assignment of polyad quantum numbers to observed transitions in these spectra, with up to 15 000 cm−1 in internal energy. Here we analyze a special subset of the identified polyads, those which involve excitation exclusively in the trans and cis bending modes: the pure bending polyads. The bending dynamics that is encoded in these polyads is analyzed using both frequency and time-domain formalisms. Among the conclusions of this analysis is that, in many ways, the observed bending dynamics is somewhat simpler at 15 000 than it is at 10 000 cm−1; this rather surprising result is explained in terms of qualitative changes in the structures of the pure bending polyads as a function of increasing internal energy.
Class III b-tubulin overexpression in gynecologic tumors: implications for the choice of microtubule targeted agents? (2012)

The tubulins are significant players in maintaining microtubule dynamics and have important signaling and apoptotic functions. Alterations in microtubules as a result of changes in tubulin isotype content or polymerization affect the sensitivity of cell lines to tubulin-binding agents (e.g., taxol) in vitro. Epothilones, such as patupilone and ixabepilone, contain a 16-membered macrolide ring and act as competitive inhibitors of taxol. Class III β-tubulin overexpression has been linked to resistance to paclitaxel and correlated with poor survival in ovarian, breast, gastric, non-small-cell lung cancer and unknown primary tumors. Recent data suggest that class III β-tubulin may not only serve as a marker for sensitivity to epothilones, but also as a mediator of a bioaggressive tumor phenotype through activation of multiple cell survival pathways active under stress conditions.
Reevaluation of general partitioning model for sorption of hydrophobic organic contaminants by soil and sediment organic matter (1999)

Abstract This evaluation of the polymer-based Flory–Huggins sorption theory has shown that the model predicts relatively concentration-independent χ values for rubbery matrices, concentration-dependent χ values for more glassy matrices, and highly concentration-dependent, largely negative interaction parameters for sorption of phenanthrene onto Green River kerogen, Ohio Shale II kerogen, Illinois No. 6 and Wyoming coals, and poly(phenyl methacrylate). These greatly negative enthalpic contributions to the interaction parameter are only to be expected where specific sorbate-sorbent interactions exist, such as in polar sorbate–polar sorbent systems. The failure of the nonlinear partitioning model is explained in terms of its inability to predict these increased interactions of sorbing solutes within microvoids present within glassy matrices. Calculations of sorbent solubility parameters through use of this model do, however, provide good agreement with literature solubility parameter values for specific sorbents; it may thus prove useful for partial characterization of sorbents for which solubility parameters are unknown.

Cross-field plasma lens for focusing of the Hall thruster plume (2014)

Hall thrusters produce neutralized ion beams with high current density because the acceleration takes place in quasi-neutral plasma and is not subject to space charge limitation. We tested an external plasma lens (PL) in front of the thruster as a means to focus the thruster plume. In the PL, the plasma is nearly collisionless, with non-magnetized flowing ions and magnetized electrons. Surprisingly, we observed anomalous electron cross-field transport, leading to large currents to the PL electrode and enhanced power loss.
A geometry-based soft shadow volume algorithm using graphics hardware (2003)

Most previous soft shadow algorithms have either suffered from aliasing, been too slow, or could only use a limited set of shadow casters and/or receivers. Therefore, we present a strengthened soft shadow volume algorithm that deals with these problems. Our critical improvements include robust penumbra wedge construction, geometry-based visibility computation, and also simplified computation through a four-dimensional texture lookup. This enables us to implement the algorithm using programmable graphics hardware, and it results in images that most often are indistinguishable from images created as the average of 1024 hard shadow images. Furthermore, our algorithm can use both arbitrary shadow casters and receivers. Also, one version of our algorithm completely avoids sampling artifacts which is rare for soft shadow algorithms. As a bonus, the four-dimensional texture lookup allows for small textured light sources, and, even video textures can be used as light sources. Our algorithm has been implemented in pure software, and also using the GeForce FX emulator with pixel shaders. Our software implementation renders soft shadows at 0.5--5 frames per second for the images in this paper. With actual hardware, we expect that our algorithm will render soft shadows in real time. An important performance measure is bandwidth usage. For the same image quality, an algorithm using the accumulated hard shadow images uses almost two orders of magnitude more bandwidth than our algorithm.
Improved ZIRLOTM Cladding Performance through Chemistry and Process Modifications (2005)

Abstract Since the introduction of the ZIRLO™ alloy for use in commercial nuclear light water reactors (LWRs) in the early nineties, work has continued on identifying chemistry and process changes to improve further the in-reactor corrosion performance of the alloy. Relative to the reference ZIRLO chemistry of Zr-1%Nb-1%Sn-0.1%Fe, a series of Zr-xNb-ySn-zFe alloys was fabricated to strip material and autoclave tested. The goal was to identify Zr-Nb-Sn-Fe compositions that would result in lower uniform corrosion rates in pure water and steam environments, while retaining resistance to accelerated corrosion in abnormal chemistry conditions, such as elevated lithium levels. The results of the study identified a reduction in tin content as having the greatest impact on improving the uniform corrosion performance. However, a minimum tin content was required to avoid accelerated corrosion in water containing 70-ppm Li. In the processing area, an extensive study was conducted to evaluate the relationship between thermal-mechanical processing, alloy microstructure (e.g., second phase particles), and corrosion performance. Processing variables following β-phase heat treatments included cold work, annealing temperature, and annealing time. Long-term autoclave tests performed in 633°K water containing 70-ppm lithium showed the uniform corrosion rate of the alloy is essentially optimized in cold-worked material after only 1 h of anneal at temperatures higher than 823°K. The autoclave results also showed a lower corrosion rate with decreasing processing temperatures. A low tin version of the ZIRLO alloy, with approximately 0.75 % tin content, was fabricated into fuel cladding and inserted as fuel rods in a commercial pressurized water reactor. After two 18-month cycles at high fuel duty and average burnups greater than 52 GWD/MTU, the peak oxide thickness in the low tin ZIRLO was significantly lower than reference ZIRLO.
Growth Signals, Inflammation, and Vascular Perturbations (2012)

Nearly 35% of adults and 20% of children in the United States are obese, defined as a body mass index ≥30 kg/m 2 . Obesity, which is accompanied by metabolic dysregulation often manifesting in the metabolic syndrome, is an established risk factor for many cancers. Within the growth-promoting, proinflammatory environment of the obese state, cross talk between macrophages, adipocytes, and epithelial cells occurs via obesity-associated hormones, cytokines, and other mediators that may enhance cancer risk and progression. This review synthesizes the evidence on key biological mechanisms underlying the obesity-cancer link, with particular emphasis on obesity-associated enhancements in growth factor signaling, inflammation, and vascular integrity processes. These interrelated pathways represent possible mechanistic targets for disrupting the obesity-cancer link.

Hierarchical real-time depth map generation algorithm (2013)

A depth map generation algorithm suitable for real-time hardware implementation is proposed. Currently, there are algorithms capable of providing high quality depth maps, but due to their complexity, they cannot be used in real-time applications. The aim of the proposed algorithm is to provide depth maps at a suitable quality for dedicated embedded applications, in the same time meeting the key requirement of matching the frame rate of the image acquisition devices.
High Field Measurement of the Critical Field in (La<sub>1-x</sub>Sr<sub>x</sub>)<sub>2</sub>CuO<sub>4</sub> up to 40 T (1987)

The upper critical field H c2 was measured for (La 1- x Sr x ) 2 CuO 4 as a function of temperature in pulsed high magnetic fields up to 40 T. At zero field, the onset of the superconducting transition was observed at 43 K. In the presence of magnetic field, a gradual increase of the magnetoresistance was observed with a positive curvature near the transition temperature. If we define H c2 by the field where the resistance becomes half of that in the normal state, the linear extrapolation of the H c2 vs temperature plot gives H c2 (0) = 70 T.
Interactive feature visualization for image retrieval (2008)

Most systems for content based image retrieval (CBIR) employ low level image features as a similarity measure. The problem of CBIR systems is that they are a ldquoblack boxrdquo to the user: Queries are specified by sample images, but the features which the CBIR system actually uses are unknown to the user. Hence, unexpected results are difficult to interpret. The problem becomes worse for inexperienced users, who expect the system to understand their query on a symbolic level, while in reality the CBIR system just extracts close-to-signal features. Here we propose to make CBIR systems more ldquotransparentrdquo by visualization of the employed features. Since non-experts should be able to operate the CBIR system, we argue that features should be visualized as prototypical, artificial images, rather than feature-specific visualizations (such as bar-diagrams for a histogram). We present the visualization of two widely used feature classes, color histograms and texture features, and evaluate in a user study how well the visualizations can be interpreted.
Effect of polyethylene bag thickness and method of sealing on dry ice removal of astringency from Japanese persimmon. (1985)

ポリエチレン袋内でドライアイスを用いて渋カキの脱渋を行うに当たっての問題点を検討した。即ち,結び目口からの気体の漏れ,被覆材の有無とドライアイス粒度の違いに基づく昇華速度及びドライアイスの昇華と袋の破損などについて実験した。(1) ポリエチレン袋の結び目口からの気体(空気)の漏れは,フィルムの厚みが増すに従って増大した。反転結びにすると直立結びに比較して漏れが少なかった。結ぶ場合の巻きつけ回数は6回以上になると漏れに殆んど差がなくなったが,3回と4回との間には大きな差があった。(2) ドライアイスを開放状態にしておくと,50gが1時間でほぼ昇華してしまったが,ポリエチレン混入ポリスチレンの発泡シート(発泡シート)で被覆すると約3時間,これを更に新聞紙2枚で包むと約5時間に延長された。(3) ドライアイスの粒度をかえて,発泡シートで被覆した場合,粒重が小さい程昇華速度は大きかった。このうち,10gと25gの間には昇華速度に大きな差がなかったが,50gでは昇華がかなり抑制された。即ち,初発重量の1/3となる時間は,1～5gで1時間42分,10g前後で1時間53分,25g前後で1時間57分,50g前後では2時間23分であった。(4) 約5lのポレエチレン袋(厚み,0.03～0.09mm)にドライアイス30gを入れ,反転8回巻きして放置した。ドライアイスを直接入れた場合には,0.07mmの厚みの袋でも破損したが,発泡シートに包むと,0.05mm以下の厚みの袋の破損にとどまった。カキ果実を入れると,ドライアイスの昇華に基づく袋の破損が抑制され,破損したのは0.03mmの厚みの袋のみであった。
Fewer Pulls Required When Using a Powered Bone Marrow Biopsy System to Obtain Core Samples in the Multiple Myeloma Patients Population (2011)

findings included lytic lesions, pathological fractures or compression fractures of vertebral bodies that were not seen well by the skeletal survey. However, there were no significant differences in the median PFS or OS between the two patient groups. There were total of 9 patients that had no bony lesions in either the survey or the CT scan and their PFS and OS were not different either. We conclude that CT scan of the skeleton is more sensitive in defining existing bony lesions in MM patients at diagnosis, although these extra findings may not have any impact on the PFS or OS of patients undergoing SCT. The CT scan findings may have implications to palliative and supportive care treatments for these patients.
Anyone for Bowling? (2014)

Despite the importance of individuals coming together for social group-activities (e.g. pick-up volleyball, chess clubs), the process by which such groups coalesce is poorly understood. Existing theories focus on adoption and contribution rates, group types, and the formation of group norms, as opposed to the processes involved in initial group coalescence. We address this gap in the literature through an interview study examining: 1) how well people's needs for social group activity engagement are being met; 2) the challenges they face in finding and participating in, and; 3) leading interest-based group activities. Our findings highlight how people-s needs are not being addressed by current technologies. In particular, they place a heavy burden on individuals to step forward into leadership positions where the return they will receive for their efforts is often unknown, or extremely limited. We discuss the implications of our findings for the design of interest-based group coalescing technology.

Protein Aggregation after Transient Cerebral Ischemia (2000)

Protein aggregates containing ubiquitinated proteins are commonly present in neurodegenerative disorders and have been considered to cause neuronal degeneration. Here, we report that transient cerebral ischemia caused severe protein aggregation in hippocampal CA1 neurons. By using ethanolic phosphotungstic acid electron microscopy (EM) and ubiquitin immunogold EM, we found that protein aggregates were accumulated in CA1 neurons destined to die 72 hr after 15 min of cerebral ischemia. Protein aggregates appeared as clumps of electron-dense materials that stained heavily for ubiquitin and were associated with various intracellular membranous structures. The protein aggregates appeared at 4 hr and progressively accumulated at 24 and 48 hr of reperfusion in CA1 dying neurons. However, they were rarely observed in dentate gyrus neurons that were resistant to ischemia. At 4 hr of reperfusion, protein aggregates were mainly associated with intracellular vesicles in the soma and dendrites, and the nuclear membrane. By 24 hr of reperfusion, the aggregates were also associated with mitochondria, the Golgi apparatus, and the dendritic plasmalemma. High-resolution confocal microscopy further demonstrated that protein aggregates containing ubiquitin were persistently and progressively accumulated in all CA1 dying neurons but not in neuronal populations that survive in this model. We conclude that proteins are severely aggregated in hippocampal neurons vulnerable to transient brain ischemia. We hypothesize that the accumulation of protein aggregates cause ischemic neuronal death.
Pathogenesis and Treatment of Type 2 Diabetic Nephropathy: Lessons from the Spontaneous KK/Ta Mouse Model (2005)

Diabetic nephropathy is a major cause of end-stage renal failure (ESRF) in patients with both type 1 and type 2 diabetes. Many factors such as genetic and non-genetic promoters, hypertension, hyperglycemia, accumulation of advanced glycation end products (AGEs), dyslipidemia, albuminuria and proteinuria influence the progression of this disease. It is important to determine pathogenesis and treatment of this disease. However, it is difficult to investigate since human diabetes is a heterogeneous and multifactorial disease. Therefore, most of these mechanisms have been investigated in animal experiments. KK/Ta mice have a clearly different genetic background in terms of body weight, blood glucose, impaired glucose tolerance (IGT), urinary albumin excretion and serum triglyceride than BALB/c mice. Renal lesions of KK/Ta mice closely resemble those in human early diabetic nephropathy. Thus, the KK/Ta mouse may serve as a suitable model for the study of type 2 diabetes and early diabetic nephropathy in humans. We reviewed genetic susceptibility using genome-wide linkage analysis and differential display polymerase chain reaction (DD-PCR) or Northern blot analysis, and treatment of diabetic nephropathy using angiotensin type 1 (AT1) receptor blockers (ARB) or thiazolidinediones (TZDs) in KK/Ta mice.
Blood Biomarkers for Uveal Melanoma (2012)

Uveal melanoma disseminates hematogenously, and blood biomarkers may be useful for prognosis and for monitoring disease progression. Melanoma-associated, metastatic and immune factors have been measured in the blood of patients with uveal melanoma, as have circulating melanoma cells. Most of the biomarkers were derived from studies in cutaneous melanoma. For various biological and/or technical reasons, these assessments have not demonstrated the accuracy required for effective prognostic or monitoring assays. Advances in uveal melanoma genomics and proteomics have generated many candidate biomarkers that are potentially measurable in blood. Measuring circulating nucleic acids may also be possible. Improvements in molecular profiling techniques that accurately predict metastatic risk in uveal melanoma patients should facilitate biomarker discovery and aid implementation in clinical testing. The stage is set to translate the advances made in understanding the molecular characteristics of uveal melanoma in order to identify and test clinically useful blood biomarkers of tumor dissemination and/or progression.

Changes in Escherichia coli outer membrane subproteome under environmental conditions inducing the viable but nonculturable state (2008)

Changes in the outer membrane subproteome of Escherichia coli along the transition to the viable but nonculturable state (VBNC) were studied. The VBNC state was triggered by exposure of E. coli cells to adverse conditions such as aquatic systems, starvation, suboptimal temperature, visible light irradiation and seawater. The subproteome, obtained according to Molloy et al., was analysed at the beginning of exposure (inoculum, phase 1), after a variable exposure time (95% of population culturable, phase 2) and when populations were mainly in the VBNC state (95% of cells VBNC, phase 3). Proteome changes were dependent on adverse conditions inducing the transition and were detected mainly in phase 2. The permanence of E. coli cells in seawater under illumination conditions entailed a dramatic rearrangement of the outer membrane subproteome involving 106 new spots, some of which could be identified by peptide fingerprinting. However, proteins exclusive to the VBNC state were not detected.
Characterisation (1987)

The depth of characterisation in the novel varies. Verloc and Winnie are conceived in terms of a fairly limited palette but, because they are placed in a number of different situations in the narrative and viewed from a range of perspectives, they acquire a certain depth. At the other extreme, there are portraits which are intentionally conceived by the author as caricatures. Figures such as Karl Yundt or Sir Ethelred exist in two dimensions only. A number of other characters — Winnie's mother, the Assistant Commissioner and Michaelis's patroness — are not even given a personal name, as if a simple designation defines sufficiently their essence and function. This kind of implicit reduction of human beings to the status of the barest kind of nomenclature is also expressed through the epithets attached repeatedly to the revolutionary characters: Michaelis, the 'ticket-of-leave apostle', or Ossipon, 'the robust anarchist', or Karl Yundt, 'the terrorist', are descriptions which quickly take on the ring of withering scorn.
Feasibility of deriving a novel imaging biomarker based on patient-specific lung elasticity for characterizing the degree of COPD in lung SBRT patients (2018)

The derivation of elasticity information directly from 4DCT imaging data is a novel method for performing lung elastography. The work demonstrates the need for a mechanics-based biomarker for representing lung pathophysiology.
