description: Background: This cohort study investigated the role of the active matrix metalloproteinase-8 (aMMP-8) and interleukin-6 (IL-6) as oral fluid biomarkers for monitoring the periodontal degeneration occurring in head and neck cancer (HNC) patients treated by radiotherapy. Research design and methods: Eleven patients, aged 28–74, diagnosed with HNC were included in the study. Complete periodontal and oral examinations were performed pre-radiotherapy and 1 month after radiotherapy. Mouthrinse samples (pre-radiotherapy, after 6 weeks of radiotherapy and 1 month after radiotherapy) were assayed by aMMP-8 point-of-care-kit (PerioSafe®/ORALyzer®) for aMMP-8 and ELISA for IL-6. Results: HNC radiotherapy had a deteriorating impact on the periodontium and a significant impact on periodontal biomarkers aMMP-8 and IL-6 and increased their levels in mouthrinse. Clinical-attachment-loss (CAL) (site of greatest loss: mean = 1.7 mm, range = 1–3 mm) corresponding to rapid progression of periodontitis. There was a positive repeated measures correlation (rmcorr = 0.667) between the aMMP-8 and IL-6 levels. Conclusions: Elevated aMMP-8 levels were observed 1 month after radiotherapy among some HNC patients suggesting a prolonged increased susceptibility to further periodontal tissue destruction. Currently available aMMP-8 point-of-care testing could be useful to monitor and assess quantitatively online and real-time the risk of deterioration of periodontal health during HNC radiotherapy.

description: Visual perception is an important part of IoT technology, with advantages such as intuitive target detection, high imaging resolution, and large information content. It is challenging to use image sensors to image through a continuously fluctuating water-air interface (WAI). The images obtained in this way will suffer from severe refraction distortion, which will affect the observer's accurate recognition of the target. Reversing these distortions is an ill-posed problem, and the current restoration methods using high-resolution video streams are difficult to adapt to real-time observation scenes. This paper proposes a method for instantaneous distorted image restoration based on structured light and local fitting.Experimental results show that the method proposed in this paper can effectively eliminate the refraction distortion of instantaneous images, improve the visual effect of the image, and its performance is significantly better than the state-of-the-art methods.

The effect of Fe and Ni catalysts on the growth of multiwalled carbon nanotubes using chemical vapor deposition

description: The effect of Fe and Ni catalysts on the synthesis of carbon nanotubes (CNTs) using atmospheric pressure chemical vapor deposition (APCVD) was investigated. Field emission scanning electron microscopy (FESEM) analysis suggests that the samples grow through a tip growth mechanism. High-resolution transmission electron microscopy (HRTEM) measurements show multiwalled carbon nanotubes (MWCNTs) with bamboo structure for Ni catalyst while iron filled straight tubes were obtained with the Fe catalyst. The X-ray diffraction (XRD) pattern indicates that nanotubes are graphitic in nature and there is no trace of carbide phases in both the cases. Low frequency Raman analysis of the bamboo-like and filled CNTs confirms the presence of radial breathing modes (RBM). The degree of graphitization of CNTs synthesized from Fe catalyst is higher than that from Ni catalyst as demonstrated by the high frequency Raman analysis. Simple models for the growth of bamboo-like and tubular catalyst filled nanotubes are proposed.

description: We analyse theoretically a relation between the vibrational generation rate of a single adsorbate by tunneling electrons and the inelastic tunneling (IET) current in scanning tunneling microscope, and the influence of the vibrational excitations on the rate of adsorbate motions. Special attention is paid to the effects of finite lifetime of the vibrational excitations. We show that in the vicinity and below the IET threshold the rate of adsorbate motion deviates from a simple power-law dependence on the bias voltage due to the effects of bath temperature and adsorbate vibrational lifetime broadenings. The temperature broadening appears to be confined near the threshold voltage within a narrow region of several $k_B T$, whereas the lifetime broadening manifests itself in a much wider region of applied voltages below the IET threshold.

description: In astronomy, we are witnessing an enormous increase in the number of source detections, precision, and diversity of measurements. Additionally, multi-epoch data is becoming the norm, making time-series analyses an important aspect of current astronomy. The Gaia mission is an outstanding example of a multi-epoch survey that provides measurements in a large diversity of domains, with its broad-band photometry; spectrophotometry in blue and red (used to derive astrophysical parameters); spectroscopy (employed to infer radial velocities, v sin(i), and other astrophysical parameters); and its extremely precise astrometry. Most of all that information is provided for sources covering the entire sky. Here, we present several properties related to the Gaia time series, such as the time sampling; the different types of measurements; the Gaia G, G BP and G RP-band photometry; and Gaia-inspired studies using the CORrelation-RAdial-VELocities data to assess the potential of the information on the radial velocity, the FWHM, and the contrast of the cross-correlation function. We also present techniques (which are used or are under development) that optimize the extraction of astrophysical information from the different instruments of Gaia, such as the principal component analysis and the multi-response regression. The detailed understanding of the behavior of the observed phenomena in the various measurement domains can lead to richer and more precise characterization of the Gaia data, including the definition of more informative attributes that serve as input to (our) machine-learning algorithms.

description: We investigate the classical stability of the higher-dimensional Schwarzschild black holes against linear perturbations, in the framework of a gauge-invariant formalism for gravitational perturbations of maximally symmetric black holes, recently developed by the authors. The perturbations are classified into the tensor, vector, and scalar-type modes according to their tensorial behaviour on the spherical section of the background metric, where the last two modes correspond respectively to the axial- and the polar-mode in the four-dimensional situation. We show that, for each mode of the perturbations, the spatial derivative part of the master equation is a positive, self-adjoint operator in the $L^2$-Hilbert space, hence that the master equation for each tensorial type of perturbations does not admit normalisable negative-modes which would describe unstable solutions. On the same Schwarzschild background, we also analyse the static perturbation of the scalar mode, and show that there exists no static perturbation which is regular everywhere outside the event horizon and well-behaved at spatial infinity. This checks the uniqueness of the higher-dimensional spherically symmetric, static, vacuum black hole, within the perturbation framework. Our strategy for the stability problem is also applicable to the other higher-dimensional maximally symmetric black holes with non-vanishing cosmological constant. We show that all possible types of maximally symmetric black holes (thus, including the higher-dimensional Schwarzschild-de Sitter and Schwarzschild-anti-de Sitter black holes) are stable against the tensor and the vector perturbations.

description: We study fluctuations in a vertically oscillated layer of grains below the critical acceleration for the onset of ordered standing waves. As onset is approached, transient disordered waves with a characteristic length scale emerge and increase in power and coherence. The scaling behavior and the shift in the onset of order agrees with the Swift-Hohenberg theory for convection in fluids. However, the noise in the granular system is four orders of magnitude larger than the thermal noise in a convecting fluid, making the effect of granular noise observable even 20% below the onset of long range order.

Wind Accretion by a Binary Stellar System and Disk Formation

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: I calculate the specific angular momentum of mass accreted by a binary system embedded in the dense wind of a mass losing asymptotic giant branch star. The accretion flow is of the Bondi-Hoyle-Lyttleton type. For most of the relevant parameters space the flow is basically an isothermal high Mach number accretion flow. I find that when the orbital plane of the accreting binary system and the orbital plane of the triple system are not parallel to each other, the accreted mass onto one or two of the binary system components has high specific angular momentum. For a large fraction of triple-star systems, accretion disks will be formed around one or two of the stars in the binary system, provided that the mass ratio of the two stars in the accreting binary system is >0.5. Such disks may blow jets which shape the descendant planetary nebula. The jets' axis will be almost parallel to the orbital plane of the triple-star system. One jet is blown outward relative to the wind, while the other jet pass near the mass losing star, and is more likely to be slowed down or deflected. I find that during the final asymptotic giant branch phase, when mass loss rate is very high, accretion disk may form for orbital separation between the accreting binary systems and the mass losing star of up to 400-800 AU. I discuss the implications for the shape of the descendant planetary nebula, and list several planetary nebulae which may have been shaped by an accreting binary star system, i.e., by a triple star system.

 Shrubs or treelets 3–3.5 m, apparently glabrous; indumentum sparse to moderately furfuraceous-stellulate, the trichomes early-caducous. Petioles 1.8–2 cm long; blade 7.5–11 × 2.3–3.2 cm, chartaceous, elliptic, base acute, apex acuminate, margin entire, abaxial surface also sparsely setulose in acrodromous veins; acrodromous veins 3–5, 7– 11 mm suprabasal; primary-axillary hair-tuft domatia in abaxial surface. Thyrsoids with no branchlets of scorpyoid cymes, 4.4–10.2 cm long; bracts 0.2–0.3 × 0.8–0.9 mm, bracteoles 0.1–0.2 × ca. 0.5 mm, both triangular-acuminate, not involucral. Flowers 5-merous; pedicelate; hypanthium 1–1.5 × 2–2.1 mm, campanulate; inner torus glandularsetulose, glabrescent; calyx with external lobes 0.4–0.6 × 0.1–0.2 mm, internal lobes 0.9–1 x 0.4–0.9 mm, narrowly triangular; petals 2.1–2.2 × 0.7–1 mm, white, reflex, oblong-attenuate; stamens with filaments 1–1.1 mm long; anthers 1.1–1.2 mm long, straight, connective 0.1–0.2 mm prolonged, unappendaged or with dorsal inconspicuous calcar; ovary 1.2–1.3 × 2.2–2.3 mm, almost completely inferior, 3-celled, glabrous; style 4–4.1 mm long. Bacidium 2.5–3 × 2.6–3 mm, light-purple, oblong; seeds 0.6–0.8 × 0.5–1 mm, obtriangular, testa granulose.
 Specimen examined:— 15.V.2010, fr., K.C. Silva & F.S. Gonçalves 96 (RBR).
 Additional specimens examined:— BRASIL. Rio de Janeiro: Guanabara, 1.VII.1971, fl., D. Sucre 8026 (RB).
 Distribution:—Endemic to Brazil, occurring from the state of Minas Gerais to Santa Catarina, and in Cerrado and Atlantic Forest Biomes (Souza & Baumgratz 2012a). It is categorized as Vulnerable in the municipality of Rio de Janeiro (Baumgratz 2000).
 Comments:—This is the first record for Marambaia. Leandra acutiflora occurs only in Dense Submontane Ombrophilous Forest, in very wet areas at about 641 m. The indumentum is apparently absent, since the stellulate trichomes are inconspicuous and become early caducous. Additional illustrations in Brade (1960), Camargo et al.

description: We re-analyzed two Rossi X-Ray Timing Explorer archival observations of the atoll source 4U 1820-30 in order to investigate the detailed time-frequency properties of the source during the intervals when a ~7 Hz QPO was detected by Wijnands et al. (1999, ApJ, 512, L39). We find that in both observations, in addition to a QPO signal lasting a couple of minutes as previously reported, there is a much narrower transient oscillation with a life time of only a few seconds. Within this time, the oscillation is consistent with being coherent. Its integrated fractional rms is around 10% and its frequency 7.3 Hz and 5.7 Hz in the two observations. We discuss the possible association of this QPO with other oscillations known both in Neutron-Star and Black-Hole systems, concentrating on the similarities with the narrow 5-7 Hz oscillations observed at high flux in Black-Hole Candidates.

description: Background: There is sparse literature evidence evaluating the applicability of the GLI-2012 spirometric norms for Australian Aboriginal adults. Methods: Lung function parameters (LFPs) were compared between Australian Aboriginal and Australian Caucasians, and the fit of Australian Aboriginals LFPs with various ethnic GLI equations was tested. Results: Of 1350 and 5634 Pulmonary function tests (PFTs) in Australian Aboriginal and Australian Caucasian adults, 153 and 208 PFTs matched for anthropometrics and normal chest radiology, respectively. Absolute FVC and FEV1 values were 20% lower in Australian Aboriginals compared to Australian Caucasians. Differences remained significant after accounting for age, sex, height, weight and smoking status in multivariate regression (FVC −0.84 L (−0.98, −0.71), FEV1 − 0.72 L (−0.84, −0.59), but with nearly preserved FEV1/FVC. GLI-2012 transformation resulted in z-scores significantly below zero for each of FVC, FEV1 and FEV1/FVC with z-scores ranging from −4.52 (−4.87, −4.16) for North East Asian FVC transformation for males, to −0.34 (−0.73, 0.05) for Black FVC transformation for females. Conclusions: Australian Aboriginal adults had 20% lower values for FVC and FEV1 but nearly preserved absolute FEV1/FVC in comparison to Australian Caucasians. The GLI-2012 spirometric norms do not appear to fit for Australian Aboriginal adults regardless of which ethnicity options selected, including ‘others/mixed’.

description: Quantum confined devices of three-dimensional topological insulators have been proposed to be promising and of great importance for studies of confined topological states and for applications in low energy-dissipative spintronics and quantum information processing. The absence of energy gap on the TI surface limits the experimental realization of a quantum confined system in three-dimensional topological insulators. This communication reports on the successful realization of single-electron transistor devices in Bi$_2$Te$_3$ nanoplates by state of the art nanofabrication techniques. Each device consists of a confined central island, two narrow constrictions that connect the central island to the source and drain, and surrounding gates. Low-temperature transport measurements demonstrate that the two narrow constrictions function as tunneling junctions and the device shows well-defined Coulomb current oscillations and Coulomb diamond shaped charge stability diagrams. This work provides a controllable and reproducible way to form quantum confined systems in three-dimensional topological insulators, which should greatly stimulate research towards confined topological states, low energy-dissipative devices and quantum information processing.

description: Using the infrared-renormalon approach, we obtain the constraints on the next-to-leading order non-singlet polarised parton densities. The advocated feature follows from the consideration of the effect revealed in the process of the next-to-leading order fits to the data for the assymetry of polarised lepton-nucleon scattering which result in the approximate nullification of the $1/Q^2$-correction to A_1^N(x,Q^2).

description: We address questions regarding construction and implications of gauge-invariant "dressed" observables in nontrivial background geometries such as that of a black hole. Formally, such observables can be constructed, e.g. by locating points with geodesics launched from infinity. However, practical complications arise in non-trivial geometries, and in particular for observables behind black hole horizons. Greater simplicity can be achieved by considering null constructions where the dressing lies along a null geodesic, or null surface such as a cone. We first investigate basic properties of these null dressings in the simpler context of electromagnetism. Since null constructions provide simple dressings for gauge-invariant observables inside black holes, they also allow us to investigate the question of compatibility of observables inside and outside black holes, and in particular the idea of black hole complementarity. While such observables in general have non-vanishing state-dependent commutators, the failure to commute does not appear particularly enhanced by the presence of the horizon.

description: We propose a "Copenhagen interpretation" for spacetime noncommutativity. The goal is to be able to predict results of simple experiments involving signal propagation directly from commutation relations. A model predicting an energy dependence of the speed of photons of the order E/E_Planck is discussed in detail. Such effects can be detectable by the GLAST telescope, to be launched in 2006.

description: An enumerative survey of cattle and hog-marketing practices of Iowa livestock farmers was conducted in March and April 1952 by the Statistical Laboratory of Iowa State College, cooperating with the Iowa Crop and Livestock Reporting Service and the Agricultural Marketing Service. The study was undertaken to learn how and to what extent livestock farmers use information from the monthly marketing intentions survey conducted by the Iowa Crop and Livestock Reporting Service. To get valid data on the subject it was necessary to learn the degree to which farmers modify short-term marketing plans and what media or sources of information affect those plans. The purpose of this paper, the first report of the study to be published, is to present a general introduction to the problem, to explain the sample design and analysis, and to summarize (1) general information collected, (2) some comparisons of respondents and nonrespondents to the mail survey, (3) farmers' use of marketing information, and (4) changes in marketing intentions. In another article, to appear in a later issue of Agricultural Economics Research, it is planned to summarize the information collected in the survey which relates to the farmers' marketing of specific lots of livestock—cattle or hogs, or both—and to describe the sources and uses of market information.

Background Gender representation trends at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Annual Meetings and the effect of the 2018 ‘We R SAGES’ initiatives are unknown. We assessed gender trends in oral presentations at the SAGES Annual Meeting between 2012 and 2022 with a focus on assessing the impact of the 2018 initiatives. Methods Abstracts selected for oral presentations from 2012 to 2022 were reviewed for presenter and first, second, and senior author gender. Gender was categorized as woman, man, or unknown using public professional profiles. Subsequent publications were identified using search engines. The primary outcome was the temporal trend of proportion of women in each role using interrupted time series analysis. Secondary outcomes included publication rates based on first and senior author genders in 2012–2018 versus 2019–2022. Results 1605 abstracts were reviewed. The proportion of women increased linearly in all categories: presenter (2.4%/year, R2 = 0.91), first author (2.4%/year, R2 = 0.90), senior author (2%/year, R2 = 0.65), and overall (2.2%, R2 = 0.91), (p < 0.01 for all). Prior to 2018, the proportion of women increased annually for presenters (coefficient: 0.026, 95% CI [0.016, 0.037], p = 0.002) and first authors (coefficient: 0.026, 95% CI [0.016, 0.037], p = 0.002), but there was no significant increase after 2018 (p > 0.05). Female second author proportion increased annually prior to 2018 (coefficient: 0.012, 95% CI [0.003, 0.021], p = 0.042) and increased by 0.139 (95% CI [0.070, 0.208], p = 0.006) in 2018. Annual female senior author proportion did not significantly change after 2018 (p > 0.05). 1198 (75.2%) abstracts led to publications. Women were as likely as men to be first (79% vs 77%, p = 0.284) or senior author (79% vs 77%, p = 0.702) in abstracts culminating in publications. There was no difference in woman first author publication rate before and after 2018 (80% vs 79%, p = 1.000), but woman senior author publication rate increased after 2018 (71% vs 83%, p = 0.032). Conclusion There was an upward trend in women surgeons’ presentations and associated publications in the SAGES Annual Meetings over the last decade.

description: Objectives: CD43 can be useful in routine flow cytometry. We conducted a systematic review aiming to describe when CD43 is used by flow cytometry in malignant hematology and to determine its value in these settings. Methods: Systematic review of MEDLINE (search ‘CD43’ AND ‘flow cytometry,’ starting in 2010). Results: Twenty-one of 103 entries retrieved were included in this systematic review. CD43 is used in three settings: 1) in the classification of mature B cell lymphoproliferative disorders, 2) as part of a strategy to quantify residual disease in chronic lymphocytic leukemia (CLL) and 3) to help classify CD10-positive B cell populations. In this section, the published data is summarized, the clinical usefulness in each of these settings is evaluated and illustrative cases are shown. Conclusion: CD43 has a growing role in the diagnosis and management of B cell malignancies; it has become essential for the classification of B cell lymphoproliferative disorders and may be of help in the differential diagnosis of CD10-positive lymphomas by FC. It is also required for optimal quantification of CLL residual disease, which will soon be used to guide therapeutic decisions.

XMM-Newton Observation of Fe Kalpha emission from a BAL QSO: Mrk 231
Creators: name: Turner, T. J.

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present results from a 20 ksec XMM observation of Mrk 231. EPIC data reveal strong line emission due to Fe Ka, which has rarely been detected in this class. The line energy is consistent with an origin in neutral Fe and the width equivalent to a velocity dispersion ~ 18,000 km/s, thus the line may be attributed to transmission and/or reflection from a distribution of emitting clouds. If, instead, the line originates in the accretion disk then the line strength and flat X-ray continuum support some contribution from reflection, although the data disfavor a model where the hard X-ray band is purely reflected X-rays from a disk. Line parameters are similar to those obtained for the BAL QSO, H1413+117.

Theoretical uncertainties in sparticle mass predictions from computational tools

description: We estimate the current theoretical uncertainty in sparticle mass predictions by comparing several state-of-the-art computations within the minimal supersymmetric standard model (MSSM). We find that the theoretical uncertainty is comparable to the expected statistical errors from the Large Hadron Collider (LHC), and significantly larger than those expected from a future e+e- Linear Collider (LC). We quantify the theoretical uncertainty on relevant sparticle observables for both LHC and LC, and show that the value of the error is significantly dependent upon the supersymmetry (SUSY) breaking parameters. We also present the theoretical uncertainty induced in fundamental-scale SUSY breaking parameters when they are fitted from LHC measurements. Two regions of the SUSY parameter space where accurate predictions are particularly difficult are examined in detail: the large tan(beta) and focus point regimes.

description: The main objective of this study was to estimate the efficacy of influenza vaccination in reducing influenza-attributable hospitalization and emergency room (ER) admission for severe complications and influenza-attributable excess mortality in individuals ≥65 years of age. We analyzed the ≥65 years-old community (n = 952,822) afferent to the Brescia (Northern Italy) Health Protection Agency, considered an Italian population reference, to evaluate the efficacy of influenza vaccination (seasons 2014–17) in reducing deaths, ER-admissions, and hospitalizations for influenza-related complications in the elderly. A protective effect of influenza vaccination emerged in reducing hospitalization and ER admission for diseases of the respiratory system and for death from all causes in people ≥65 years. The major effect of influenza vaccination was the reduction in risk of death from all causes, increasing with age and comorbidity. Influenza vaccination has reduced the number of ER admissions and hospitalizations caused by influenza-related complications and has prevented death among high-risk groups in elderly ≥65 years, resulting in social and public health cost savings. Stronger or new vaccination strategies are needed to improve vaccination rates among the elderly.

Problems in the Analysis of Food Consumption

Subjects: Food Consumption/Nutrition/Food Safety

description: The choice among several concepts of food consumption depends upon what is to be studied, whether a farm problem, a marketing problem, or a problem at the level of consumer purchase or food intake. That choice will largely determine the selection among possible measures of food consumption. No single measure of changes in food consumption can be designed to meet every need. In this paper, the meanings of food consumption that are set forth, together with their related measures, are those involved in questions frequently raised by Government analysts and information specialists, by nutritionists, farm organizations, advertising agencies, and journalists, and by businessmen in the food industries, and other interested individuals. As the author indicates, the intrinsic differences among the several meanings of food consumption are so significant that they materially affect the conclusions drawn from the analysis of specific problems.

description: We argue that the demand of background independence in a quantum theory of gravity calls for an extension of standard geometric quantum mechanics. We discuss a possible kinematical and dynamical generalization of the latter by way of a quantum covariance of the state space. Specifically, we apply our scheme to the problem of a background independent formulation of Matrix Theory.

description: An area of research in agricultural economics hitherto largely neglected was introduced with the recent publication of "Trade in Horticultural Specialties," 1 which was issued by the Bureau of Agricultural Economics last April. The data in this statistical compendium constitute the basis for further research in this field. That the industry is of economic importance may be seen in the fact that at midcentury the value of sales and inventory of horticultural specialty goods and services in this country exceeded $1.5 billion. The labor force of the industry was more than a quarter million persons, with a payroll of more than $300 million. Cash receipts from horticultural specialties in 1952 surpassed those of such outstanding farm products as potatoes, apples, oranges, sugar beets and cane, wool, turkeys, and sheep and lambs. Some of the aspects of economic research in the horticultural specialties were considered at a workshop conducted last summer by the Foundation for Floriculture, in cooperation with BAE. In the accompanying paper Mr. Fossum follows up with an outline of the principal areas of economic investigation in this fertile field.
