Design of a Modular and Efficient CAMAC/Lab VIEW-Based Data Acquisition System for a Time of Flight PET Test-Bed

A high-speed data acquisition (DAQ) system has been designed for a time of flight PET test-bed. The requirements of the system were flexibility, data throughput and data integrity. The software is modular so that modifications and additions can be integrated easily into the existing software architecture. The program operation is driven by commands read from a script file, simplifying implementation of complex acquisition sequences. The heart of the program is the DAQ module, which efficiently transfers data from CAMAC to file. Another software module offers online or offline analysis capabilities. The software, written in LabVIEW, communicates with a novel high-speed USB2 CAMAC controller (CCUSB). The CCUSB offers significant improvements over its GPIB predecessor, supporting FIFO buffered DAQ and a variety of data readout modes. Four readout modes have been evaluated in order to maximize the DAQ rate for this particular system. A highest sustained data rate of 15.7 k events/s was achieved for approximately 60 input channels using a 22Na flood phantom. Flexibility in the software design accommodates both current and future hardware configurations without the need to edit the LabVIEW code.
A unified spectrum sensing and throughput analysis model in cognitive radio networks

Cognitive radio CR is a newly developed technology for increasing spectral efficiency in wireless communication systems. In the CR networks, there exist two traditional spectrum-sharing technologies called spectrum overlay and spectrum underlay. A new hybrid overlay/underlay paradigm has also been discussed in the literature. In this work, we create a unified spectrum sensing and throughput analysis model, which is suitable for overlay, underlay, and hybrid overlay/underlay paradigms in the CR networks. In the proposed model, the energy detection scheme is employed for the spectrum sensing in the network in which the co-channel interference is present among primary users and secondary users SUs. The SUs' throughput in the proposed CR system model is then analyzed. The simulations are also carried out for demonstrating the performance of overlay, underlay, and hybrid overlay/underlay paradigms. Copyright © 2013 John Wiley & Sons, Ltd.
Effect of aphidicolin on avian sarcoma virus replication

We studied the effect of aphidicolin, an inhibitor of eucaryotic DNA polymerase alpha, on viral DNA replication and integration during the first 24 h after infection of quail embryo fibroblasts with avian sarcoma virus. In drug-treated cells, the synthesis of unintegrated linear viral DNA species was not impaired; however, the subsequent accumulation of circular viral DNA species and integrated proviral DNA was reversibly inhibited. After removal of the drug, circular viral DNA species were derived from preexisting linear viral DNA species, instead of being derived by de novo synthesis.

Impacto do robustecimento de sistemas no desempenho de serviços Internet

O recurso a medidas preventivas, no âmbito da Seguranca de Sistemas Informaticos, tem uma importância cada vez maior. Neste contexto, os mecanismos do tipo Role-Based Access Control (RBAC) representam uma das abordagens mais promissoras. Todavia, para que sejam largamente aceites, e desejavel que i) tenham um impacto reduzido no desempenho dos sistemas e aplicacoes, ii) sejam escalaveis e iii) sejam facilmente administraveis. Para alem da abordagem RBAC, existem outros mecanismos complementares, para a deteccao e contencao de erros. Por exemplo, mecanismos como o PaX intervem ao nivel da gestao de memoria efectuada pelo nucleo do sistema operativo, tornando um sistema virtualmente imune a situacoes do tipo bu er over ow. Neste artigo descreve-se uma aplicacao (e respectiva avaliacao) do mecanismo RBAC da plataforma grsecurity1, baseado em listas de controle de acesso (ACLs), em conjuncao com a plataforma PaX. Em tracos gerais, e para a gama de testes utilizada, concluimos que, para servicos nos quais a memoria e partilhada entre os varios os de execucao que fazem o atendimento dos pedidos, o impacto do hardening no desempenho dos servicos e minimo; ja em situacoes em que a memoria nao e partilhada, a intervencao dos mecanismos de validacao PaX torna-se evidente, prejudicando o desempenho global dos servicos.
Outcomes of robotic vs laparoscopic hepatectomy: A systematic review and meta-analysis.

AIM To perform a systematic review and meta-analysis on robotic-assisted vs laparoscopic liver resections. METHODS A systematic literature search was performed using PubMed, Scopus and the Cochrane Library Central. Participants of any age and sex, who underwent robotic or laparoscopic liver resection were considered following these criteria: (1) studies comparing robotic and laparoscopic liver resection; (2) studies reporting at least one perioperative outcome; and (3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measures were set for estimated blood loss, operative time, conversion rate, R1 resection rate, morbidity and mortality rates, hospital stay and major hepatectomy rates. RESULTS A total of 7 articles, published between 2010 and 2014, fulfilled the selection criteria. The laparoscopic approach was associated with a significant reduction in blood loss and lower operative time (MD = 83.96, 95%CI: 10.51-157.41, P = 0.03; MD = 68.43, 95%CI: 39.22-97.65, P < 0.00001, respectively). No differences were found with respect to conversion rate, R1 resection rate, morbidity and hospital stay. CONCLUSION Laparoscopic liver resection resulted in reduced blood loss and shorter surgical times compared to robotic liver resections. There was no difference in conversion rate, R1 resection rate, morbidity and length of postoperative stay.
Implication de réseaux de récepteurs membranaires dans la signalisation du NGF et de son précurseur dans les cellules cancéreuses de sein

Notre laboratoire a montre que le NGF et les neurotrophines sont des facteurs determinants de la cancerogenese mammaire, et plus particulierement de la croissance et de l’invasion des cellules cancereuses de sein. Les effets du NGF dependent, entre autres, de l’activation du recepteur a activite tyrosine kinase TrkA. Recemment, nous avons decrit que le precurseur du NGF, le proNGF, est egalement produit et secrete par les cellules cancereuses de sein pour induire leur invasion via la formation d’un complexe sortiline/TrkA. Neanmoins, les differentes signalisations induites par le NGF et le proNGF ne sont pas encore parfaitement decryptees dans le cancer du sein. Au cours de ma these, j’ai demontre que le NGF et le proNGF induisent des complexes de recepteurs distincts. Ainsi, alors que le NGF conduit a la formation d’un complexe membranaire TrkA/CD44, le proNGF recrute quant a lui la sortiline, TrkA et EphA2. En outre, les etudes in vivo, realisees dans un modele de souris SCID, montrent que la croissance tumorale est dependante de la formation de ces complexes. Ainsi, l’administration conjointe d’un inhibiteur de l’activite kinase de TrkA (CEP-701) et d’un ARN interferent dirige soit contre CD44, soit contre EphA2, diminue significativement le volume tumoral en comparaison a l’utilisation en monotherapie du CEP-701 ou d’un siEphA2 ou du siCD44. L’ensemble de mes resultats a permis d’approfondir les mecanismes d’action du NGF et de son precurseur dans les cellules cancereuses mammaires et suggere l’existence de mecanismes de resistance a travers les cooperations TrkA/CD44 et TrkA/EphA2, ouvrant ainsi l’opportunite a de nouvelles strategies therapeutiques dans les cancers.
Designing CT bandpass ΣΔ modulators with arbitrary STF shapes

In this paper the automated design of continuous-time bandpass ΣΔ modulators with arbitrary signal-transfer-functions is described. State-of-the-art design methodologies rely on multiple transformations to obtain continuous-time bandpass modulators. Moreover, they are mainly focused on the NTF in order to achieve the required SNR. A design approach, which allows to realize a specified signal-transfer function is not known in the state-of-the-art. In contrast to that the web-based design tool www.sigma-delta.de allows STF engineering for bandpass modulators as first of its kind. The STF is optimized with regard to user defined specifications while the signal-to-noise ratio of the modulator is maximized. This work gives a general introduction to the tool and explains the features concerning bandpass modulators in detail together with corresponding examples.
Visual health assessment of North Atlantic right whales (Eubalaena glacialis) using photographs

Although trends in reproduction, mortality, and entanglement events have been analyzed for the endangered North Atlantic right whale (Eubalaena glacialis) population, no method has been available to assess individual right whale health. Here, we describe a technique for assessing health based on evaluation of selected physical parameters from archived photographs of right whales. A scoring system was developed to assess body and skin condition, blowhole cyamids, and rake marks in over 200 000 photographs. Comparison of body condition scores of females during calving and noncalving years found that females were significantly thinner in calving years and in the year after calving compared with the year before calving, showing that changes in body condition known to occur during the reproductive cycle can be successfully evaluated from photographs. Comparison of scores for all parameters between living whales and whales with more than a 5-year gap in sighting history ("presumed dead") found that presumed dea.
Modified duobinary polarization-shift keying transmission scheme

A new version of duobinary polarization-shift keying scheme is proposed. The relocation of the duobinary filter at the receiver side and the optimization of both transmitter and receiver electrical filters offer a receiver sensitivity improvement while maintaining chromatic dispersion tolerance. The main reason for this sensitivity enhancement is the reduction of the timing jitter and the noise narrow filtering provided. Moreover, the system is more tolerant against fiber nonlinear effects.
IL-15–Independent Maintenance of Tissue-Resident and Boosted Effector Memory CD8 T Cells

IL-15 regulates central and effector memory CD8 T cell (TCM and TEM, respectively) homeostatic proliferation, maintenance, and longevity. Consequently, IL-15 availability hypothetically defines the carrying capacity for total memory CD8 T cells within the host. In conflict with this hypothesis, previous observations demonstrated that boosting generates preternaturally abundant TEM that increases the total quantity of memory CD8 T cells in mice. In this article, we provide a potential mechanistic explanation by reporting that boosted circulating TEM do not require IL-15 for maintenance. We also investigated tissue-resident memory CD8 T cells (TRM), which protect nonlymphoid tissues from reinfection. We observed up to a 50-fold increase in the total magnitude of TRM in mouse mucosal tissues after boosting, suggesting that the memory T cell capacity in tissues is flexible and that TRM may not be under the same homeostatic regulation as primary central memory CD8 T cells and TEM. Further analysis identified distinct TRM populations that depended on IL-15 for homeostatic proliferation and survival, depended on IL-15 for homeostatic proliferation but not for survival, or did not depend on IL-15 for either process. These observations on the numerical regulation of T cell memory indicate that there may be significant heterogeneity among distinct TRM populations and also argue against the common perception that developing vaccines that confer protection by establishing abundant TEM and TRM will necessarily erode immunity to previously encountered pathogens as the result of competition for IL-15.
Lexical coding vs. syntactic marking of homogeneity: Evidence from Spanish and Danish

The purpose of this article is to substantiate the claim that the semantic feature of homogeneity manifests itself differently in different languages. By contrasting data from Spanish and Danish it is shown that homogeneity is lexically coded in Danish nouns, whereas Spanish nouns are lexically neutral to homogeneity. In Spanish the homogeneity interpretation of nouns is determined when they are inserted into a syntactic structure. The empirical relevance of this assumption is assessed by investigating syntactic and semantic aspects related to the occurrence of bare nominals in object position in the two languages under scrutiny. It is well-known that Spanish as a canonical pattern does not semantically license bare singular nouns with count interpretation (BNs) in object position, viz. #Juan repara coche [Juan repairs car], while in Danish the occurrence of BNs in object position is both possible and normal, viz. Ole maler hus [Ole paints house]. It is argued that this contrast is a predictable consequence of the premise that, in Spanish, transitive activity verbs impose a mass reading on any bare object noun whereas, in Danish, BNs maintain their lexically encoded denotation as inhomogeneous entities. However, contrasting with the leading pattern, the so-called HAVE-verbs (Borthen, 2003) actually license Spanish BNs in object position (cf., e.g., Espinal, 2010; Espinal & Mcnally, 2011), viz. Juan tiene perro [Juan has dog]. It is claimed that the occurrence of BNs in these cases is strongly related to the assumption that HAVE-verbs, contrary to activity verbs, are functionally non-eventive and, therefore, do not impose a specific homogeneity reading on the bare noun in object position.

Dependence of Delayed Luminescence upon Adenosine Triphosphatase Activity in Chlorella.

Delayed luminescence and fluorescence yield after illumination by a short flash were measured in Chlorella pyrenoidosa in the presence of 3-(3,4-dichlorophenyl)-1,1-dimethylurea. Addition of tri-N-butyl-tin (TNBT), a specific inhibitor of ATPase, drastically increases the life-time of the reduced photosystem II primary acceptor Q(-) and decreases the intensity of delayed luminescence. This indicates a slowing of the charge recombination between the oxidized donor and reduced acceptor of photosystem II centers. No inhibition is observed in isolated chloroplasts when the membrane is permeable to ions, i.e. in the presence of Gramicidin D and KCl.It is suggested that there exists in dark-adapted algae a permanent proton gradient which stimulates the charge recombination process. This proton gradient results from the hydrolysis of a pool of ATP by membrane-bound ATPases and collapses after the addition of TNBT. The long lifetime of this proton gradient (several hours) indicates that the ATP probably comes from the mitochondria.The rate of the back reaction occurring from state S(3) (as defined by Kok, Forbush, and McGloin 1970 Photochem Photobiol 11: 457-475) is more dependent upon the pH gradient than for state S(2).
Fixed or random effects meta-analysis? Common methodological issues in systematic reviews of effectiveness

ABSTRACTSystematic review aims to systematically identify, critically appraise, and summarize all relevant studies that match predefined criteria and answer predefined questions. The most common type of systematic review is that assessing the effectiveness of an intervention or therapy. In this article, we discuss some of the common methodological issues that arise when conducting systematic reviews and meta-analyses of effectiveness data, including issues related to study designs, meta-analysis, and the use and interpretation of effect sizes.

Loss of heterozygosity of 1p in uveal melanomas with monosomy 3

Gains and losses of chromosomes 1, 3, 6 and 8 are nonrandom chromosomal aberrations in uveal melanoma. Monosomy 3 is the most frequent abnormality and is associated with poor prognosis. To identify regions of allelic loss on the short arm of chromosome 1 and to investigate if these alterations contribute to uveal melanoma progression, we performed microsatellite analysis of 10 loci in 70 uveal melanomas. A total of 51 tumors were obtained from patients with clinical follow‐up data, 19 tumors were from recent patients without follow‐up. Loss of heterozygosity (LOH) of at least 1 marker was more frequent in tumors with monosomy 3 (40%) than in tumors with disomy 3 (10%). In particular, loss of the entire short arm of chromosome 1 was only observed in tumors with monosomy 3 (p = 0.0001). By comparing the extent of 1p LOH in all tumors with monosomy 3, we were able to define a smallest region of overlap (SRO) of approximately 55 Mb, which is flanked by markers D1S507 and D1S198. On the basis of our data and published cytogenetic data, we propose that 1p31 harbors genes involved in the progression of uveal melanoma with monosomy 3. © 2005 Wiley‐Liss, Inc.
Childhood Misfortune and Adult Health in a National Study

This study investigated the relationship between childhood misfortune and 10-year change in health and whether this relationship was mediated by the quality of social relations. We used data from the Midlife in the United States (MIDUS) national longitudinal study, 1995–1996 (Time 1) and 2005–2006 (Time 2). Childhood misfortune was measured at Time 1 using indicators of financial strain, family structure, and abuse. Self-rated physical and mental health indicators were obtained at both occasions. The measure of quality of social relations was based on items relative to social support and social strain from spouse, friends, and family at Time 1. Mediational models showed that a higher level of childhood misfortune was associated with low-quality family relations which in turn tend to account for change in mental health. These findings suggest that childhood misfortune is associated with the quality of social relations, which in turn explain individual changes in mental health in adulthood.
Chronic blockade of angiotensin II formation during sodium deprivation.

The present study was designed to investigate the mechanisms by which the renin-angiotensin system (RAS) regulates arterial pressure (AP) and renal function during chronic sodium deprivation. Intravenous infusion of the converting enzyme inhibitor SQ 14225 (14 microgram.kg-1.mm-1) for 8 days in 12 sodium-deficient dogs caused a marked decrease in AP from 90 +/- 1 to 67 +/- 2 mmHg and a reduction in glomerular filtration rate (GFR), filtration fraction (FF), and plasma aldosterone concentration (PAC). Despite the fall in AP and GFR, urinary Na excretion and effective renal plasma flow (ERPF) increased above control levels. In four dogs, infusion of aldosterone (200 micrograms/day) for 8 days during continuous SQ 14225 infusion restored PAC to levels above control, but did not significantly change AP or renal function from the values observed during SQ 14225 infusion alone. However, infusion of angiotensin II (AII) (10 or 20 ng.kg-1.min-1) for 5--8 days during continuous SQ 14225 infusion almost completely restored AP and renal function to control levels. These data indicate that the RAS plays a major role in regulating AP, renal hemodynamics, and Na excretion during Na deprivation, probably through the direct effects of AII rather than through changes in PAC.
