Analysis of modified structures by Rayleigh quotient (2021)

In structural vibrations, the Rayleigh quotient may be used to calculate the natural frequency (or eigenvalue) of a structure given the corresponding mode shape (or eigenvector). Previous works have shown that the eigenvalue may be calculated relatively accurately using the Rayleigh quotient as long as an appropriate guess is made for the eigenvector. Typically, the Rayleigh quotient is used to predict the eigenvalues when the structure does not change. However, in this work the structure will be modified and the change in the eigenvalue will be predicted using the Rayleigh quotient. In order to use the Rayleigh quotient a guess for the eigenvector must be made. Here, the displacement vector of the nominal structure forced near a resonance will be used as the guess. Analysis and computations will be done for an undamped beam that is harmonically forced. To modify the structure, the stiffness elements will be scaled. Using this approach, it will be demonstrated that changes in the natural frequencies can be predicted relatively quickly for a modified structure. In addition, this method provides insight into which elements should be scaled to get the greatest frequency change. [Work supported by ONR under Grant N00014-19-1-2100.]

High Resolution Imaging with ClearPET™ Neuro - First Animal Images (2005)

The ClearPET™ Neuro is the first full ring scanner within the Crystal Clear Collaboration (CCC). It consists of 80 detector modules allocated to 20 cassettes. LSO and LuYAP:Ce crystals in phoswich configuration in combination with position sensitive photomultiplier tubes are used to achieve high sensitivity and realize the acquisition of the depth of interaction (DOI) information. The complete system has been tested concerning the mechanical and electronical stability and interplay. Moreover, suitable corrections have been implemented into the reconstruction procedure to ensure high image quality. We present first results which show the successful operation of the ClearPET™ Neuro for artefact free and high resolution small animal imaging. Based on these results during the past few months the ClearPET™ Neuro System has been modified in order to optimize the performance.
Rapid traffic information dissemination using named data (2012)

This paper applies the Named Data Networking (NDN) concept to vehicle-to-vehicle (V2V) communications. Specifically, we develop a simple traffic information dissemination application based on the data naming design from our previous work and evaluate its performance through simulations. Our simulation results show that data names can greatly facilitate the forwarding process for Interest and data packets. With adequate vehicle density, data can propagate over long distances robustly at tens of kilometers per second, and a requester can retrieve the desired traffic information 10km away in a matter of seconds.
HDAC inhibitor valproic acid upregulates CAR in vitro and in vivo (2007)

CAR upregulation through HDAC inhibition was observed in the three cancer cell lines with enhancement of adenoviral transduction. CAR upregulation was also observed in tumor samples obtained from patients with cervical cancer treated with therapeutic doses of valproic acid. These results support the addition of the HDAC inhibitor valproic acid to adenoviral mediated cancer gene therapy clinical trials to enhance adenoviral mediated gene delivery to the tumor cells.
Simulation of the Unsteady Gas Flow through a Three-way Automotive Catalyst: A Preliminary Study (2005)

This paper describes a model of a 1.8-litre four-cylinder four-stroke gasoline engine fitted with a close-coupled three-way catalyst (TWC). Designed to meet EURO 3 emissions standards, the engine includes some advanced emission control features in addition to the TWC, namely: variable valve timing (VVT), swirl control plates, and exhaust gas recirculation (EGR). Gas flow is treated as one-dimensional (1D) and unsteady in the engine ducting and in the catalyst. Reflection and transmission of pressure waves at the boundaries of the catalyst monolith are modelled. In-cylinder combustion is represented by a two-zone burn model with dissociation and reaction kinetics. A single Wiebe analysis of measured in-cylinder pressure data is used to determine the mass fraction burned as a function of crank angle (CA) at each engine speed. Measured data from steady-state dynamometer tests are presented for operation at wide open throttle (WOT) over a range of engine speeds. These results include CA-resolved traces of pressure at various locations throughout the engine together with cycle-averaged traces of gas composition entering the catalyst as indicated by a fast-response emissions analyser. Simulated engine performance and pressure wave action throughout the engine are well validated by the measured data.
Survey of macromoths (Insecta: Lepidoptera) of a Palouse prairie remnant site in Eastern Washington State (2014)

In its broadest sense, The Palouse or Palouse prairie is an ecoregion consisting primarily of native grasses, shrubs, and forbs that originally covered over 16,000 km2 of central Idaho, southeastern Washington, and northeastern Oregon. It is estimated that only 1–6% of this habitat remains with much of it having been converted to agriculture. The Kramer Palouse Natural Area is a relatively undisturbed, 11.7-ha remnant of Palouse prairie situated in Whitman County, Washington. During 2004–05 we conducted a light-trapping and hand-netting survey of a set of families of moths, collectively referred to as macromoths, on the Kramer site. The purpose of this study was to document the biological diversity of moths occurring on the site. This paper reports on just over 5,100 specimens and 150 species in 7 families: Cossidae (usually considered a micromoth — one species), Thyatiridae (one species) Lasiocampidae (one species), Notodontidae (three species), Sphingidae (five species), Erebidae (14 species), and Noctuidae (125 species). We collected no Nolidae or Euteliidae and, although Geometridae are considered macromoths, they are not discussed in this paper. Seasonal and subjective abundance information is presented for all species. Although no species of strict conservation concern were collected, our study indicates that remaining areas of Palouse prairie are able to support a significant species diversity of macromoths, which are otherwise uncommon in surrounding areas, and probably represent an ancestral fauna.
Mitigation of the impact of single-walled carbon nanotubes on a freshwater green algae:Pseudokirchneriella subcapitata (2011)

This study investigates the biological response of Pseudokirchneriella subcapitata to single-walled carbon nanotubes (SWNTs) suspended in gum Arabic (GA), using typical 96-hour algal bioassays and long-term growth studies. Changes in algal biomass and cell morphology associated with specific SWNT-treatments were monitored and the mechanisms of observed biological responses investigated through a combination of biochemical and spectroscopic methods. Results from short-term bioassays showed a growth inhibition in culture media containing >0.5 mg SWNT/L and a final GA concentration of 0.023% (v/v). Interestingly, the observed toxicity disappears when GA concentrations are brought to levels ≥ 0.046%. Long-term experiments based on toxic combination of SWNTs and GA showed that P. subcapitata would easily recover from an initial growth inhibition effect. Overall, these findings point to the possibility of GA to mitigate the toxicity of SWNTs, making it an ideal surfactant if SWNT suspension in GA does not alter the performance sought from these nanotubes.
Preoperative astigmatic influence on the predictability of intraocular lens power calculation (1990)

The preoperative and postoperative influence of different parameters on the predictability of formulas used for intraocular lens (IOL) power calculation (axial length, corneal dioptric power, IOL malposition, postoperative astigmatism) has been shown by various authors. In this study, we evaluated the preoperative astigmatic influence on the prediction of postoperative refraction in eyes operated on for cataract with IOL implantation. Three hundred and fifty-nine eyes were evaluated after cataract surgery and IOL implantation. We calculated predictive errors of both the Binkhorst and SRK formulas for each eye. Based on the outcome of the predictive errors we divided the eyes into six groups: three of high and three of low predictability. Preoperative astigmatism in these groups was statistically compared (using the Student's t-test). The preoperative astigmatism was always higher in the group with low predictability than in the group with high predictability (P less than .05).
Successful Removal of a Severed Transvenous Pacemaker Electrode (1981)

The ease and simplicity of the transvenous approach to permanent pacing continue to be among its greatest advantages. However in a small proportion of transvenously paced patients complications can occur. A rare complication is an incompletely removed pacing catheter with subsequent embolization to more central parts of the cardiovascular system. This communication reports the migration of a severed transvenous pacemaker electrode and its removal from the left iliac vein with a femoral-ventricular pigtail catheter.
Green Shadows, White Whale (2020)

In 1991 Bradbury was able to combine his various stories of Ireland with bridges that told the tale of his Irish adventures writing the Moby Dick screenplay for John Huston in 1953-1954 to form the autobiographical novel Green Shadows, White Whale. Chapter 29 describes how Bradbury was able to merge these complex projects by revisiting the rough winter he spent under Huston’s demanding direction. In the process, Bradbury was able to capture the defining spirit of the Ireland he knew with good humor and only a touch of satire. Bradbury loved the beauty of the countryside and the people, but he would never return. The chapter analyzes this ambivalence through Bradbury’s reflective poem “To Ireland,” and concludes with the comments that Bradbury offered at the 1991 memorial service for his friend Gene Roddenberry.
Cerebral edema and priapism in an adolescent with acute lymphoblastic leukemia (1999)

Priapism and increased intracranial pressure are both rare, but recognized, manifestations of leukemia. However, they have never been reported in the same patient. We report a 15-year-old male with acute lymphoblastic leukemia who presented with hyperleukocytosis, priapism, and increased intracranial pressure. Central nervous system leukostasis and cerebral edema may have been detected earlier, had his history of priapism been known. Management of hyperleukocytosis complicated by priapism and increased intracranial pressure is discussed.
Rapid identification of Brucella isolates to the species level by real time PCR based single nucleotide polymorphism (SNP) analysis (2008)

The multiple-outcome assay described represents a new tool for the rapid, simple and unambiguous characterisation of Brucella to the species level. Furthermore, being based on a robust phylogenetic framework, the assay provides a platform that can readily be extended in the future to incorporate newly identified Brucella groups, to further type at the subspecies level, or to include markers for additional useful characteristics.
Direct evidence for degradation of polaron excited states in organic light emitting diodes (2009)

We investigate the intrinsic degradation mechanisms of the prototypical phosphorescent emissive material fac-tris(2-phenylpyridine) iridium [Ir(ppy)3] doped into the host 4, 4′-bis(3-methylcarbazol-9-yl)-2,2′-biphenyl (mCBP) by separately evaluating the effects of unipolar current, optical excitation, and their combination. We find that the mCBP anion is unstable and becomes more so in its excited state. Degradation due to the formation of defect states is evident from changes in the capacitance-voltage characteristics and from increasing drive voltage over time of a unipolar test device. These changes are understood within the framework of trapped-charge-limited transport, allowing for the determination of rate constants for each degradation mechanism. We also observe degradation of the hole transport material 4, 4′-bis[N-(1-naphthyl)-N-phenyl-amino]-biphenyl under sub-energy-gap illumination and suggest that this instability may proceed through excitation of its cationic state. These results provide direct evidence for polaron-induced degradation that limits the operational lifetime of organic light emitting diodes.
Validity of accelerometry for the assessment of moderate intensity physical activity in the field (2000)

The count versus METs relationship for accelerometry was found to be dependent on the type of activity performed, which may be due to the inability of accelerometers to detect increased energy cost from upper body movement, load carriage, or changes in surface or terrain. This may introduce error in attempts to use accelerometry to assess point estimates of physical activity energy expenditure in free-living situations.
Towards optimal pathologic staging of resectable non-small cell lung cancer. (2013)

Pathologic nodal staging is the most accurate means of determining prognosis of patients with resectable non-small cell lung cancer (NSCLC), but confusion prevails about the optimal pre-operative and surgical lymph node examination procedures for candidates of curative-intent resection. The landmark American College of Surgeons Oncology Group Z0030 trial revealed no difference in the survival of patients with clinical T1 or T2, N0 or N1 (hilar node-negative), M0 NSCLC who either had a fastidious, pre-defined systematic hilar and mediastinal lymph node sampling procedure, or who received a complete mediastinal lymph node dissection. We place the results of this major trial into a contemporary clinical practice context, and discuss problems associated with apparent misunderstanding of the lessons from this trial, especially in light of evidence of prevailing sub-optimal nodal examination practices. We also discuss evolving knowledge about the origin of the quality gap in pathologic nodal staging and the emerging literature on corrective interventions.
Forecasting for Grid and Cloud Computing On-Demand Resources Based on Pattern Matching (2010)

The Cloud phenomenon brings along the cost-saving benefit of dynamic scaling. As a result, the question of efficient resource scaling arises. Prediction is necessary as the virtual resources that Cloud computing uses have a setup time that is not negligible. We propose an approach to the problem of workload prediction based on identifying similar past occurrences of the current short-term workload history. We present in detail the Cloud client resource auto-scaling algorithm that uses the above approach to help when scaling decisions are made, as well as experimental results by using real-world traces from Cloud and Grid platforms. We also present an overall evaluation of this approach, its potential and usefulness for enabling efficient auto-scaling of Cloud user resources.
Serotonin Receptors in Hippocampus (2012)

Serotonin is an ancient molecular signal and a recognized neurotransmitter brainwide distributed with particular presence in hippocampus. Almost all serotonin receptor subtypes are expressed in hippocampus, which implicates an intricate modulating system, considering that they can be localized as autosynaptic, presynaptic, and postsynaptic receptors, even colocalized within the same cell and being target of homo- and heterodimerization. Neurons and glia, including immune cells, integrate a functional network that uses several serotonin receptors to regulate their roles in this particular part of the limbic system.

Genetic Signatures of HPV-related and Unrelated Oropharyngeal Carcinoma and Their Prognostic Implications (2009)

Genetic signatures of HPV-related and HPV-unrelated OSCC are different and most likely underlie differences in tumor development and progression. In addition, distinct chromosomal alterations have prognostic significance.
Synthesis of LiNi0.5Mn1.5O4Cathode Materials with Different Additives: Effects on Structural, Morphological and Electrochemical Properties (2016)

In this work, LiNi0.5 Mn1.5 O4 spinel type materials have been prepared by spray drying an aqueous solution of acetates and subsequent calcination of the dried precursors. Three different additives, namely polyvinylpyrrolidon (PVP), citric acid and urea have been used and their influences on the structure, morphology and electrochemical performance of the final cathode materials have been examined. Results show that the employed additives increase the purity of the disordered spinel phase and thus lead to higher discharge capacities. By the use of PVP and citric acid, a more stable cycling behavior and a better rate capability are achieved due to the well-controlled secondary particle morphology. Regarding the microstructural changes, flake-like secondary particle morphology has been observed for the use of PVP in the synthesis process, as in former work reported [J. Power Sources, 293, 137 (2015)]. The evolution of this structure is examined in more detail and possible way of formation is proposed.
Enação e processo de trabalho: uma abordagem atuacionista da ação operatória (2007)

Este artigo, baseado no novo paradigma das ciências cognitivas, convida a uma ruptura ontológica com a abordagem objetivista da representação operatória em Ergonomia Cognitiva. O atuacionismo é um ponto de vista incorporado-enativo. Ou seja, processos cognitivos emergem ou enagem pelos agentes (trabalhadores). A abordagem atuacionista pode fornecer significativas contribuições à Ergonomia. Este trabalho é o resultado de pesquisa realizada em sistemas reais de produção, pelos métodos de Análise Ergonômica do Trabalho. Ele identificou e caracterizou uma falha ontológica, presente nas análises da atividade operatória: Observador isolado do objeto observado pelas distinções de atuação entre ambos. Isso resulta em diferenças de ação, percepção e interpretação, as quais, historicamente, têm tornado impraticável um conhecimento aprofundado sobre o funcionamento do processo de trabalho. Atualmente, os processos que aparentam ser rotineiros, parcelados e manuais abrigam uma nova noção de competência, a competência atuacionista ou cognitiva, necessária para conferir continuidade e fluxo à produção.
Nonlinear harmonic generation and proposed experimental verification in SASE FELs. (1999)

Recently, a 3D, polychromatic, nonlinear simulation code was developed to study the growth of nonlinear harmonics in self-amplified spontaneous emission (SASE) free-electron lasers (FELs). The simulation was applied to the parameters for each stage of the Advanced Photon Source (APS) SASE FEL, intended for operation in the visible, UV, and short UV wavelength regimes, respectively, to study the presence of nonlinear harmonic generation. Significant nonlinear harmonic growth is seen. Here, a discussion of the code development, the APS SASE FEL, the simulations and results, and, finally, the proposed experimental procedure for verification of such nonlinear harmonic generation at the APS SASE FEL will be given.
Problems created in attenuation-corrected SPECT images by artifacts in attenuation maps: a simulation study. (2005)

Our study strongly recommends that at least a visual inspection of the quality of attenuation maps be performed before their use in compensation procedures. To improve image quality, remove artifacts, and increase diagnostic confidence, attenuation maps used in the correction procedure must be accurate and free of artifacts.
Inorganic Compounds with Unusual Properties (1976)

Electrical conductivity and thermopower measurements on single crystals of Pt(NH3)4PtCl4 (MGS) and (TTF) NiS4C4H4 (TTF = tetrathiafulvalene) illustrate the application of electrical property measurements to the study of intermolecular interactions and electronic structure in planar metal complex systems. MGS is an anisotropic, p-type semiconductor; conductivity along the metal-chain direction (10-5—10-2 ohm-1 cm-1 at 52°C) is 18—25-fold that perpendicular to this direction. The importance of impurity effects in determining the conductivity of this compound is demonstrated, and a possible extrinsic band model for the conduction process is presented. Conductivity measurements on the donor—acceptor compound (TTF)2NiS4C4H4 as a function of direction in the crystal are discussed in the context of a recent crystal structure analysis which suggests a two-dimensional interaction among the constituent TTF units.
Normal and Shear Forces Generated during the Ordering (Directed Assembly) of Confined Straight and Curved Nanowires (2007)

The effects of shape on nanowire interactions and shear-induced ordering were studied. Both the normal and lateral forces were sensitive to the particles' curvature. (i) No adhesion was observed between the confining surfaces, and the force profiles were short-ranged and mostly reversible for straight wires but longer-ranged and irreversible for curved wires. (ii) Structural phase transitions can occur in confined nanoparticle films. (iii) During shearing, straight wires order or align more easily than curved wires.
Mid-IR interband cascade light emitting diodes based on type-II quantum wells (2002)

We can circumvent the fast phonon scattering loss in type-I QC lasers, while retaining the cascaded tunneling injection advantage, by utilizing photon emission between an electron state and a hole state in a new class of QC lasers based on type-II QWs, which was first proposed by Yang and is referred to as type-II QC lasers. The type-II QC lasers can have a higher radiative efficiency because the phonon relaxation process is greatly suppressed in an interband transition. Here, we report the first observation of mid-IR electroluminescence in such a type-II QC laser structure. We illustrates the band diagram of two periods of an InAs-AlSb-GaSb type-II QC laser diode under a forward bias.
Ion Mobility Spectrometer with Radial Collisional Focusing (2004)

An ion mobility spectrometer that has its mobility cell as a 20-segment quadrupole and functionally the q2 of a triple-quadrupole mass spectrometer has been assembled and tested. The combination of high cell pressure (maximum of 4 Torr of helium) and low axial field (20-160 V per 20.2 cm) results in negligible internal excitation of the ions despite applications of rf and axial fields. The presence of collisional focusing ensures efficient ion transmission and good sensitivity. Collision cross sections of atomic, cluster, peptide, and protein ions were measured and found comparable to literature and calculated cross sections.
