68Ga-DOTANOC PET/CT in Patients With Carcinoma of Unknown Primary of Neuroendocrine Origin

Objective: To evaluate the role of 68Ga-DOTANOC (68Gallium-labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI3-octreotide) PET/CT for localization of the primary tumor in patients with carcinoma of unknown primary of neuroendocrine origin. Material and Methods: Twenty patients (median age, 55 years; male 10) with histopathologically proven metastatic neuroendocrine tumor and no localization of primary tumor on conventional imaging were included in the study. PET/CT was done after injection of 132–222 MBq (4–6 mCi) of 68Ga-DOTANOC. Images were evaluated by 2 experienced nuclear medicine physicians both qualitatively as well as quantitatively (maximum standardized uptake value). Histopathology (when available) and/or follow-up imaging with biochemical markers were taken as reference standard. Results: 68Ga-DOTANOC PET/CT localized the primary tumor in 12/20 (60%) patients. Midgut was the most common site of primary tumor (n = 9); duodenum (4), ileum (4), and colon (1). In 1 patient each the primary was localized to the pancreas, stomach, and lung. In these 12 patients, significant correlation was found between maximum standardized uptake value of primary tumor and metastasis (&rgr; = 0.615; P = 0.041). Even in patients in whom no primary tumor was localized, additional sites of metastatic disease were observed when compared with conventional imaging, mostly in lymph nodes and bones. There was a change in management in 3/20 patients (15%), who underwent surgery. In the remaining 17 patients, demonstration of somatostatin receptor expression by PET/CT made them suitable candidate for peptide receptor radionuclide therapy. Conclusion: 68Ga-DOTANOC PET/CT seems to be a promising modality for detecting primary tumor in patients with carcinoma of unknown primary of neuroendocrine origin.
Neurosis and social class. I. Social interaction.

We advance the hypothesis that the diagnosis of neurosis is the resultant of an interaction process involving the patient, the doctor, and the social group. A psychiatric census shows that the prevalence of neurosis is positively correlated with social level and that there are important differences in method of referral of neurotics from the various social classes. [SEE SOURCE PDF FOR TABLE 5] By use of a psychological symptom scale, we describe a class configuration, ranging from subjective, introversive symptoms in the top classes to somatic complaints and behavioral difficulties in the lower classes. A social interaction index reveals that the locus of conflict progressed through increasingly wider areas of social dislocation—ranging from intrapersonal symptoms in Classes I and II to severe social and legal collisions in lower Classes IV and V. Correlation of all psychological symptoms and social interaction shows this consistent increase in social difficulties. The correlation of character disorder an.
Measurement of electrical activity of the human small intestine using surface electrodes

A noninvasive technique for measuring electrical activity of the small intestine by placing electrodes on the abdominal skin over the small intestine is introduced. Surface recordings were obtained in ten healthy volunteers, three patients with total gastrectomy and five patients with gastroparesis (a slight degree of paralysis of the mucosal coat of the stomach). An omnipresent 9-12-cpm electrical activity was observed in all surface recordings. The findings from the surface electrodes were consistent with those reported in the literature for implanted or intubated electrodes. It is concluded that the technique is effective for noninvasive measurement of electrical activity of the small intestine and may have potential application in medical research and clinical diagnosis. <<ETX>>

T-eigenfaces selection for false face reduction

We have developed a false face reduction algorithm dedicated for face detection in an unconstrained environment, based on the discriminative facial T-shape region constructed by human eyes, nose, and mouth. The algorithm started with a detected face, through lighting compensation, normalization, facial T-shape region extraction, and eigenface selection using genetic algorithms to classify face/false face robustly. Results of face detection with and without the proposed false face reducer show substantial improvements on precision rate at a little loss of recall rate.
Microfossils in stromatolitic cherts from the upper proterozoic Min'yar formation, southern Ural Mountains, USSR.

A diverse assemblage of exceptionally well-preserved microorganisms, including several previously unknown taxa, has been discovered in stromatolitic black chert from the ca. 680-790 Ma-old Min'yar Formation (Suite) of the southern Ural Mountains, USSR. Like most ancient and modern stromatolitic communities, the Min'yar microflora is dominated by filamentous and unicellular cyanobacteria. Geologic evidence indicates that the microbial community inhabited a shallow water, presumably marine environment. The microfossils occur in two interlaminated and thinly interbedded sedimentary fabrics: 1, fact to wavy-laminated Stratifera-like stromatolitic laminae that presumably were deposited during periods of little wave action; and 2, intraclast grainstone that formed as a result of desiccation and (or) wave agitation. Microfossils are both better preserved and more abundant in the intraclasts than in the Stratifera-like laminae. The occurrence of probable pseudomorphs after replacement of sulfate minerals provides additional evidence for a shallow water, periodically emergent depositional environment for the Min'yar microbial mats. Kerogenous microfossils are three-dimensionally preserved, permineralized in fine-grained silica of primary or early diagenetic origin. In many aspects the Min'yar assemblage is comparable to that of the well-known ca. 850 Ma-old Bitter Springs Formation of central Australia. The following taxa are herein described: Division? Schizomycophyta or ? Cyanophyta, Biocatenoides sp. ; Family Oscillatoriaceae, Eomycetopsis robusta Schopf emend. Knoll and Golubic, Rhicnonema antiquum Hofmann, Entosphaeroides? sp. , Palaeolyngbya? sp. , Siphonophycus capitaneum n. gen., n. sp. ; Family? Oscillatoriaceae or? Rivulariaceae, Caudiculophycus? sp. ; Family? Scytonemataceae or? Stigonemataceae, Ramivaginalis uralensis n. gen., n. sp. ; Family Chroococcaceae, Sphaerophycus medium Horodyski and Donaldson, Eosynechococcus amadeus Knoll and Golubic, Gloeodiniopsis lamellosa Schopf emend. Knoll and Golubic, Gloeodiniopsis magna n. sp. , Eoaphanocapsa oparinii n. gen., n. sp. ; Division? Chlorophycophyta or? Rhodophycophyta, Glenobotrydion majorinum Schopf and Blacic. Also discussed in the taxonomic section, but not formally described, are intermediate-diameter tubular sheaths (Oscillatoriaceae), small tubular sheaths enclosed by larger tubular sheaths (Oscillatoriaceae? ), and undifferentiated spheroidal unicells.
Individual luteolysis post GnRH-agonist-trigger in GnRH-antagonist protocols

Abstract Over the past few years, the use of Gonadotropin-releasing-hormone (GnRH)-agonist for final oocyte maturation in GnRH-antagonist-protocols in stimulated IVF/ICSI cycles has gained worldwide acceptance, as this approach reduces significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Final oocyte maturation with GnRH-agonist leads to sever luteolysis, which cannot be counterbalanced using standard luteal phase support with purely progesterone (P4) application and therefore administration of hCG or high doses of P4 is considered to be essential to prevent/counteract luteolysis. However, lately publications indicate, that luteolysis is not always complete after GnRH-agonist for trigger. This case-series evaluates the degree of luteolysis in high-responder-patients, who received GnRH-agonist for final oocyte maturation. Assessment of estradiol (E2)- and P4-levels 48 h after oocyte-pick-up (OPU) procedure demonstrate clearly, that luteolysis after GnRH-agonist trigger is individual-specific, even in high-responder patients with the same number of oocytes. Hence, individualization of luteal phase support with the focus on avoiding unnecessary administration of hCG, bearing the risk for development of OHSS, a new concept of luteal coasting needs to be developed, based on severity of luteolysis following luteal coasting.
A hybrid framework for capacity and coverage optimization in self-organizing LTE networks

In this paper, we address the capacity and coverage optimization (CCO) problem for LTE networks by means of self-organizing network (SON) techniques. A novel hybrid two-layer optimization framework is proposed to enhance the network capacity and coverage, where on the top layer a network entity of eCoordinator is implemented to ensure overall network coverage by optimizing the antenna tilt and capacity-coverage weight of each cell in a centralized manner, and on the bottom layer individual eNB optimizes cell-specific capacity and coverage by tuning its pilot power in a distributed manner. A heuristic algorithm is developed for the eCoordinator operation at large time granularity and the Genetic Programming (GP) approach is exploited for the eNB operation at small time granularity, for the purpose of tracking overall network performance as well as adapting to network dynamics. Our simulation results have demonstrated the usefulness of the proposed algorithms by enhancing network capacity and coverage performance under various system requirements.
Interfaçage d'une commande externe à un simulateur en temps réel d'entraînements électriques

En depit de l'ingeniosite des chercheurs et de la puissance des mathematiques entourant les theories de la commande moderne, rares sont les nouveaux schemes de controle qui sont appliques en industrie faute de validation experimentale. La simulation en temps differe presente une porte de sortie a ce probleme. Toutefois, ce type de simulation presente deux inconvenients majeurs. Premierement, chacune des simulations exigent un temps important. Deuxiemement, ce type de simulation utilise la modelisation du controleur et non le controleur reel. La simulation en temps reel permet de combler ces manques car il est alors possible de raccorder un controleur au simulateur. C'est l'etape que nous allons franchir dans ce memoire. D'excellents resultats de simulation en boucle ouverte et en boucle fermee sont presentes dans ce travail ce qui confirme la validite de l'approche.
Paradigms Admitting Superunitary Behaviour in Parallel Computation

The phenomenon of a disproportionate decrease in execution time of p2 over p1 processors executing a task in parallel, where p2 > p1, is referred to as superunitary speedup. An analogous phenomenon that we call superunitary ‘success ratio’ occurs in dealing with tasks that can either succeed or fail, when there is a disproportionate increase in the success of p2 over p1 processors. We identify a range of conditions which may lead to superunitary speedup or superunitary success ratio, and propose several new paradigms for problems which admit such superunitary behaviour. Our results suggest that a new theory of parallel computation may be required to accommodate these new paradigms.
Cumulus cloud base height estimation from high spatial resolution Landsat data: a Hough transform approach

This study develops a semiautomated methodology for estimating cumulus cloud base heights using high-spatial-resolution Landsat multispectral scanner data. The approach employs a variety of image processing techniques to match cloud edges with their corresponding shadow edges. Cloud base height is then estimated by computing the separation between the corresponding generalized Hough transform reference points. Sixteen subregions, each 30 km*30 km in size, are selected for four Landsat scenes. Standard deviations of cloud base height within each of the subregion range from about 100 m to 150 m. Differences between cloud base heights computed using the Hough transform and a manual verification technique are small. It is estimated that cloud base height accuracies of 50-70 m may be possible using HIRIS and ASTER instruments in the Earth Observation Satellite (EOS) Global Climate Change program. >
Interplay of TRIM28 and DNA methylation in controlling human endogenous retroelements

Reverse transcription-derived sequences account for at least half of the human genome. Although these retroelements are formidable motors of evolution, they can occasionally cause disease, and accordingly are inactivated during early embryogenesis through epigenetic mechanisms. In the mouse, at least for endogenous retroviruses, important mediators of this process are the tetrapod-specific KRAB-containing zinc finger proteins (KRAB-ZFPs) and their cofactor TRIM28. The present study demonstrates that KRAB/TRIM28-mediated regulation is responsible for controlling a very broad range of human-specific endogenous retroelements (EREs) in human embryonic stem (ES) cells and that it exerts, as a consequence, a marked effect on the transcriptional dynamics of these cells. It further reveals reciprocal dependence between TRIM28 recruitment at specific families of EREs and DNA methylation. It finally points to the importance of persistent TRIM28-mediated control of ERE transcriptional impact beyond their presumed inactivation by DNA methylation.
Epidermal Growth Factor Receptor Protects Proliferating Cell Nuclear Antigen from Cullin 4A Protein-mediated Proteolysis*

Background: Phosphorylation of the proliferating protein PCNA through the signaling of receptor tyrosine kinases (RTKs) protects it from ubiquitylation-mediated degraded on the chromatin. Results: The ubiquitylation enzyme CUL4A is responsible for PCNA degradation in the absence of phosphorylation. Conclusion: Phosphorylation of PCNA stabilizes PCNA by blocking interaction between PCNA and CUL4A. Significance: This may help sensitize cancer cells to therapeutic agents targeting RTKs. Proliferating cell nuclear antigen (PCNA) is an essential component for DNA synthesis upon growth stimulation. It has been shown that phosphorylation of PCNA at Tyr-211 by the EGF receptor (EGFR) protects PCNA from polyubiquitylation and degradation, whereas blocking phosphorylation induces ubiquitylation-mediated degradation of the chromatin-bound, but not the -unbound, PCNA, and suppresses cell proliferation. However, the ubiquitin E3 ligase linking growth signaling to the proteolysis of PCNA and the underlying regulatory mechanism remain to be identified. Here we show that, in the absence of Tyr-211 phosphorylation, PCNA is subject to polyubiquitylation at Lys-164 by the CUL4A E3 ligase, resulting in the degradation of PCNA. Mutation of Lys-164 to arginine prevents PCNA ubiquitylation and rescues the degradation of the K164R/Y211F PCNA double mutant. Activation of EGFR inhibits the interaction of PCNA with CUL4A, whereas inhibition of EGFR leads to increased CUL4A-PCNA interaction and CUL4A-dependent ubiquitin-mediated degradation of PCNA. Substitution of endogenous PCNA with the Y211F mutant PCNA conveys enhanced sensitization to EGFR inhibition. Our findings identify CUL4A as the ubiquitin ligase linking the down-regulation of cell surface receptor tyrosine kinase to the nuclear DNA replication machinery in cancer cells.
Vision field capturing and its applications in 3DTV

3D video capturing acquires the visual information in 3D manner, which possesses the first step of the entire 3DTV system chain before 3D coding, transmission and visualization. The 3D capturing plays an important role because precise 3D visual capturing will benefit the whole 3DTV system. During the past decades, various kinds of capturing system have been built for different applications such as FTV[1], 3DTV, 3D movie, etc. As the cost of sensors reduces in recent years, a lot of systems utilize multiple cameras to acquire visual information, which is called multiview capturing. 3D information can be further extracted through multiview geometry. We will first give a brief review of these multiview systems and analyze their relationship from the perspective of plenoptic function [2]. Along with the multiple cameras, a lot of systems also make use of multiple lights to control the illumination condition. A new concept of vision field is presented in this talk according to the view-light-time subspace, which can be derived from the plenoptic function. The features and applications for each capturing system will be emphasized as well as the important issues in capturing like synchronization and calibration. Besides the multiple camera systems, some new techniques using TOF (time-offlight) camera [3] and 3D scanner will also be included in this talk.
Performance analysis of access control and resource management methods in heterogeneous networks

El escenario actual de las redes moviles se caracteriza por la creciente demanda de los usuarios por los servicios de datos, circunstancia que se ha visto potenciada por la popularidad de los telefonos inteligentes y el auge de aplicaciones que necesitan de una conexion permanente a internet, como aquellas que hacen uso de recursos en la nube o los servicios de streaming para video. El consumo de datos crece exponencialmente, tanto para los paises desarrollados como en los paises en desarrollo, y esto ha llevado a los operadores a plantearse soluciones que hagan el mejor uso de las tecnologias disponibles. Las redes heterogeneas se caracterizan por utilizar diferentes tecnologias de una manera coherente y organizada para proveer a los usuarios con la calidad de servicio requerida en sus comunicaciones, de tal manera que la comunicacion sea para estos transparente. Dicha heterogeneidad se puede dar a nivel de acceso radio, con la coexistencia espacial de tecnologias como 802.11, WiMAX y redes moviles en sus diferentes generaciones, o tambien a nivel de capas dentro de las redes moviles por medio de macro, micro, pico y femto celdas. A traves de un uso organizado de estos multiples recursos, es posible optimizar las prestaciones de la red y proveer a los usuarios con una mejor calidad de servicio. Otra caracteristica de las redes heterogeneas consiste en la habilidad de hacer un uso eficiente del espectro electromagnetico. Junto a las soluciones tradicionales enfocadas en el diseno de antenas o en tecnicas de modulacion avanzadas, en los ultimos anos ha ganado terreno la idea de permitir un acceso dinamico al espectro por medio de la tecnologia denominada cognitive radio. Por medio de esta tecnologia es posible que un usuario sea capaz de medir el instante en el que una parte del espectro electromagnetico no esta siendo utilizado para enviar informacion, siempre evitando interferir en las comunicaciones de aquellos usuarios que usan dicho espectro regularmente. En el presente trabajo se analizan tres soluciones en el contexto de las redes heterogeneas desde el punto de vista de la gestion de recursos y del control de acceso. En la primera parte, se estudia un problema de admision de control conjunto, en el cual se presenta un sistema con dos tecnologias de acceso y dos tipos de servicio. Diferentes politicas son planteadas y un analisis detallado permite plantear el uso eficiente del handover vertical. En la segunda parte se analiza un sistema de acceso dinamico al espectro con el objetivo de estudiar el impacto que los canales fraccionales de reserva tienen sobre la capacidad de realizar handovers espectrales y de esta manera optimizar las prestaciones del sistema. Finalmente, en la ultima parte del trabajo se plantea un problema de gestion de la localizacion para una red de smallcells, y se plantean y evaluan dos soluciones para reducir el trafico asociado a la senalizacion por medio de un sistema de anclado local y enlaces directos entre las small cells.
Comparison of computational accuracy between the fast inhomogeneous plane wave algorithm and the fast multipole method

The fast inhomogeneous plane wave algorithm (FIPWA) is an alternative way of the diagonal factorization in B. Hu et al (1999). The Green's function in FIPWA is represented by the integration for the infinite path in the complex plane. Therefore, the main error sources in the numerical implementation are due to the truncation of the integration path and extrapolation. They are different from those of the fast multipole method (FMM) by V. Rokhlin et al (1990). In this paper, we will make a comparison of computational accuracy and clarify that FIPWA has some advantages over FMM.
Vers une algèbre des relations de discours

Dans cette these, nous abordons la question de la construction d'une "algebre" des relations de discours (ou relations rhetoriques) - en s'inspirant de l'algebre temporelle de Allen (1983) - constituee d'un ensemble de regles de deduction de relations de discours. Disposer de telles regles presente un interet dans le cadre de l'analyse automatique du discours, en permettant de deduire des informations implicitement contenues dans des annotations manuelles ou automatiques, pour aider l'annotation ou comparer plusieurs annotations d'un meme discours. Or, les theories d'analyse du discours ne definissent pas ou peu de regles de ce type. La these se concentre donc sur cette question. Nous abordons l'ensemble des questions soulevees par la construction d'une algebre des relations de discours, qui concernent les proprietes des structures discursives, des relations, et des ensembles de relations. Apres avoir adopte un ensemble de relations, nous proposons une methodologie visant a identifier, en partant de deux relations R1(a,b) et R2(b,c), l'ensemble des relations pouvant etre etablies entre a et c. La methodologie allie l'examen des liens semantiques associes aux relations en jeu, l'analyse de donnees construites et de donnees empiriques, extraites automatiquement en s'appuyant sur la presence de connecteurs de discours. Pour l'analyse des donnees, plusieurs tests linguistiques sont proposes pour determiner si les unites a et c sont reliees rhetoriquement, et si oui, par quelle relation. Cette methodologie est declinee sur un ensemble de premisses mettant en jeu des interaction; entre differents "groupes" de relations : les relations temporelles, causales, et adversatives.
