Radiation-induced myocardial perfusion abnormalities in breast cancer patients following external beam radiation therapy

Objective(s): Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. Methods: To minimize potential confounding factors, only those patients with low 10-year risk of coronary artery disease (based on Framingham risk scoring) were included. All patients were initially treated by modified radical mastectomy and then were managed by postoperative 3D Conformal Radiation Therapy (CRT) to the surgical bed with an additional 1-cm margin, delivered by 46-50 Gy (in 2 Gy daily fractions) over a 5-week course. The same dose-adjusted chemotherapy regimen (including anthracyclines, cyclophosphamide and taxol) was given to all patients. Six months after radiation therapy, all patients underwent cardiac SPECT for the evaluation of myocardial perfusion. Results: A total of 71 patients with a mean age of 45.3±7.2 years [35 patients with leftsided breast cancer (exposed) and 36 patients with right-sided cancer (controls)] were enrolled. Dose-volume histogram (DVH) [showing the percentage of the heart exposed to >50% of radiation] was significantly higher in patients with left-sided breast cancer. Visual interpretation detected perfusion abnormalities in 42.9% of cases and 16.7% of controls (P=0.02, Odds ratio=1.46). In semiquantitative segmental analysis, only apical (28.6% versus 8.3%, P=0.03) and anterolateral (17.1% versus 2.8%, P=0.049) walls showed significantly reduced myocardial perfusion in the exposed group. Summed Stress Score (SSS) of>3 was observed in twelve cases (34.3%), while in five of the controls (13.9%),(Odds ratio=1.3). There was no significant difference between the groups regarding left ventricular ejection fraction. Conclusion: The risk of radiation induced myocardial perfusion abnormality in patients treated with CRT on the left hemi thorax is not low. It is reasonable to minimize the volume of the heart being in the field of radiation employing didactic radiation planning techniques. Also it is advisable to screen these patients with MPI-SPECT, even if they are clinically asymptomatic, as early diagnosis and treatment of silent ischemia may change the outcome.
Overview of the Multimedia Information Access System Components Speech Transcription

There have been several new systems for multimedia information access reported in recent years. The system presented here shares many of their aspects, but it differs in a significant way from them; it extends the realm of multimedia access to include speaker-based information. We have already prototyped and reported such a system elsewhere whose main features include SVAPI-based speaker recognition combined with speech recognition for joint textand speaker-based retrieval from audio and video. A vital component of such a system is speaker identification whose performance degrades for utterances smaller than eight seconds to such an extent that such segments have to be dismissed with a catch-all, neutral label. Here, we use a Bayesian Information Criterion based speaker clustering technique to analyze the same audio data. The results of this classifier are combined with those from our SVAPI-based speaker classifier using a decision integration scheme to produce new labels for many such short speaker segments. We discuss the details of this combined analysis and its results. We additionally report on a on-the-fly speaker enrollment scheme using this BIC-based speaker clustering technique.
Cell proliferation in human epiretinal membranes: characterization of cell types and correlation with disease condition and duration

Purpose To quantify the extent of cellular proliferation and immunohistochemically characterize the proliferating cell types in epiretinal membranes (ERMs) from four different conditions: proliferative vitreoretinopathy (PVR), proliferative diabetic retinopathy, post–retinal detachment, and idiopathic ERM. Methods Forty-six ERMs were removed from patients undergoing vitrectomy and immediately fixed in paraformaldehyde. The membranes were processed whole and immunolabeled with either anti-MIB-1 or anti-SP6 to detect the Ki-67 protein in proliferating cells, in combination with anti-glial fibrillary acidic protein or anti-vimentin to identify glia, anti-ezrin to identify retinal pigment epithelial cells, Ricinus communis to identify immune cells, and Hoechst to label nuclei. Digital images were collected using a laser scanning confocal microscope. The cell types were identified, their combined proliferative indices were tabulated as the average number of anti-Ki-67-positive cells/mm2 of tissue, and the number of dividing cells was related to the specific ocular condition and estimated disease duration. Results ERMs of all four types were shown to be highly cellular and contained proliferating cells identified as glia, retinal pigment epithelium, and of immune origin. In general, membranes identified as PVR had many more Ki-67-positive cells in comparison to those in the other three categories, with the average number of Ki-67-positive cells identified per mm2 of tissue being 20.9 for proliferative diabetic retinopathy, 138.3 for PVR, 12.2 for post–retinal detachment, and 19.3 for idiopathic ERM. While all membrane types had dividing cells, their number was a relatively small fraction of the total number of cells present. Conclusions The four ERM types studied demonstrated different cell types actively dividing at the time of removal, confirming that proliferation is a common event and does continue over many months. The low number of dividing cells at the time of removal in comparison to the total number of cells present, however, is an indicator that proliferation alone may not be responsible for the problems observed with the ERMs. Treatment strategies may need to take into consideration the timing of drug administration, as well as the contractile and possibly the inflammatory characteristics of the membranes to prevent the ensuing effects on the retina.

Skillful manipulation based on high-speed sensory-motor fusion

This video introduces the demonstration of skillful manipulation using a high-speed robot system. The system consists of visual and tactile sensors at a rate of 1 kHz and a high-speed hand-arm manipulator. The high-speed sensory-motor fusion improves not just the speed of existing robot manipulations, but robotic skills by introducing the features peculiar to high-speed motion. Based on such a concept, new variations of skillful manipulation were achieved.
An Efficient Object Tracking Method on Quad-/Oc-Trees

We introduce a fast error-free tracking method applicable to sequences of two and three dimensional images. The core idea is to use Quadtree (resp. Octree) data structures for representing the spatial discretization of an image in two (resp. three) spatial dimensions. This representation enables one to merge into large computational cells the regions that can be faithfully described with such a coarse representation, thus significantly reducing the total number of degrees of freedom that are processed, without compromising accuracy. This encoding is particularly effective in the case of algorithms based on moving fronts, since the adaptive refinement provides a natural means to focus the processing resources on information near the moving front. In this paper, we use an existing contour based tracker and reformulate it to the case of Quad-/Oc-tree data structures. Relevant mathematical assumptions and derivations are presented for this purpose. We then demonstrate that, on standard bio-medical image sequences, a speed up of 5X is easily achieved in 2D and about 10X in 3D.
Atrial natriuretic factor release during hypovolemia and after volume replacement

ObjectiveTo examine plasma atrial natriuretic factor activity during hypovolemia and after vascular volume replacement. DesignProspective, descriptive study. SettingsScene of emergency, Emergency Department, and the ICU of a university hospital. PatientsA total of 47 trauma patients with evidence of hypovolemia were grouped according to their major injury into a thoracic injury group (15 patients; mean Injury Severity Score = 38.5 ± 3.1 [SEM], Hospital Trauma Index = 14.1 ± 0.7), an abdominal injury group (14 patients; Injury Severity Score = 36 ± 3.3, Hospital Trauma Index = 14 ± 0.9), and a severe head injury group (18 patients; Injury Severity Score = 23 ± 1.5, Hospital Trauma Index = 10 ± 0.6). Measurements and Main ResultsMeasurements were taken at the scene of emergency; after volume replacement in the Emergency Department; and after 3,7,12,24,36 hrs and on day 5 in the ICU. In all groups, the average plasma atrial natriuretic factor levels were increased at the scene of emergency and declined significantly to normal values with volume replacement. In the thoracic injury group, plasma atrial natriuretic factor activity decreased from 253 ± 73 to 115 ± 83 pg/mL (p < .0017); in the abdominal injury group, plasma atrial natriuretic factor activity decreased from 194 ± 42 to 91 ± 24 pg/mL (p< .006); in the severe head injury group, plasma atrial natriuretic factor activity decreased from 167 ± 28 to 70 ± 13 pg/mL (p < .02) with volume replacement. Plasma atrial natriuretic factor levels at the scene of emergency were significantly (252 ± 73 vs. 167 ± 28 pg/mL;p < .05) higher in the thoracic injury group and in the abdominal injury group (194 ± 42 vs. 167 ± 28 pg/mL;p < .05), as compared with the severe head injury group. ConclusionsIn trauma patients, plasma atrial natriuretic factor concentrations were markedly increased in patients with untreated hypovolemia and were decreased to normal values with vascular volume replacement. Thus, atrial natriuretic factor seems to play an important physiologic role during hypovolemia.
Theories of Anxiety

This book is an up-dated version of the original text, which results from eighteen years of continuing research and reflection by Fischer. His work has three purposes: 1) to acquaint the student of psychology with a variety of approaches to the phenomenon of anxiety; 2) to explore the reasons for the fact that most psychologists seem to concur as to the significance of anxiety, but are completely at odds when describing its constitutive aspects; and 3) to make an initial effort at surpassing this paradoxical situation by reawakening the naive, everyday experience of anxiety. Chapter 12, which was not part of the original text, presents a summary of Fischer's current thinking about anxiety. Co-published with the Center for Advanced Research in Phenomenology.
Voices of Resilience from the Bottom Rungs: The Stories of Three Elementary Core French Teachers in Ontario

This paper reports on a study that used activity theory (AT) as a framework to understand the dialogical relationship between three elementary Core French (CF) teachers’ personal and professional experiences and their literacy teaching beliefs and practices. This study used a case study design collecting data from three different teachers in three different locations by means of semi-structured interviews to help capture teachers’ perspective of their professional experiences. The interviews exposed the teachers’ creativity in dealing with concerns about their personal and professional goals and (limited) resources available, documented facilitating or constraining effects on the community that operated within the same activity system, and identified unspoken agendas of their wider professional communities. The analysis of the teachers’ narratives reveals that the definition of the status and role of CF within the Canadian educational context is an essential source of tension that affects the teachers’ teaching practices and their sense of professional identity. Cet article porte sur une etude ayant comme cadre la theorie de l’activite pour comprendre le rapport dialogique entre les experiences personnelles et professionnelles de trois enseignantes de francais de base a l’elementaire d’une part, et leurs croyances et pratiques par rapport a l’enseignement de la litteratie d’autre part. Cette etude repose sur modele d’etude de cas et a implique la collecte de donnees par le biais d’entrevues semi-structurees aupres de trois enseignants differents dans trois lieux differents de sorte a obtenir leur point de vue quant a leurs experiences professionnelles. Les entrevues ont revele la creativite des enseignants face a leurs preoccupations relatives a leurs buts personnels et professionnels et les ressources limitees disponibles; documente les effets facilitateurs ou restrictifs sur la communaute qui fonctionnait au sein du meme systeme d’activites; et identifie les intentions tacites de leurs communautes professionnelles elargies. L’analyse des recits des enseignants a demontre que la definition du statut et du role du francais de base dans le milieu educatif Canadien est une source de tension qui affecte leurs pratiques pedagogiques ainsi que le sens de leur identite professionnelle.
The semi-supervised switchboard transcription project

In previous work, we proposed a new graph-based semisupervised learning (SSL) algorithm and showed that it outperforms other state-of-the-art SSL approaches for classifying documents and web-pages. Here we use a multi-threaded implementation in order to scale the algorithm to very large data sets. We treat the phonetically annotated portion of the Switchboard transcription project (STP) as labeled data and automatically annotate (at the phonetic level) the Switchboard I (SWB) training set and show that our proposed approach outperforms stateof-the-art SSL algorithms as well as a state-of-the-art strictly supervised classifier. As a result, we have STP-style annotations of the entire SWB-I training set which we refer to as semisupervised STP (S3TP).
Pilot assisted SNR estimation in a non-coherent M-FSK receiver with a carrier frequency offset

Pilot-assisted estimation of signal-to-noise ratio (SNR) is considered for an orthogonal non-coherent M-ary FSK receiver having a carrier frequency offset (CFO) at the front end. The received signal is also corrupted by symbol-rate Rayleigh fading and additive white Gaussian noise. A two-step estimation procedure is designed by observing received data in the receiver. In the first step, an asymptotically unbiased estimate of CFO is obtained using a moments based approach. This estimate is then used to derive a maximum-likelihood estimator for the SNR. The Cramer Rao Bound for SNR has been derived to compare the overall estimator performance in terms of its variance.
On selecting policy analysis models by forecast accuracy

The value of selecting the best forecasting model as the basis for empirical economic policy analysis is questioned. When no model coincides with the data generation process, non-causal statistical devices may provide the best available forecasts: examples from recent work include intercept corrections and differenced-data VARs. However, the resulting models need have no policy implications. A â€˜paradoxâ€™ may result if their forecasts induce policy changes which can be used to improve the statistical forecast. This suggests correcting statistical forecasts by using the econometric modelâ€™s estimate of the â€˜scenarioâ€™ change. An application to UK consumers expenditure illustrates the analysis.
Preference for trees, optimism and physical, psychological and social wellbeing among high school students / Preferencia hacia el árbol, optimismo y bienestar físico, psicológico y social en estudiantes

Abstract A study was performed examining the influence of preference for trees on self-reported levels of physical, psychological and social wellbeing, mediated by optimism, among 323 students in their final years of high school. Findings indicated that the greater the preference for trees, the greater the individual’s optimism, which in turn influenced physical, psychological and social wellbeing. These findings could be important because they pertain to teenagers in school education, residing in a metropolitan area with over four million inhabitants, with a very low ratio of trees to inhabitants. The results could be used in public policy to target this sector of the population in tree planting and environmental education campaigns in ecologically depressed urban areas.
A ontology-based process modelling for XP

We describe the Extreme Programming Ontology (XPO), a formal model specifying the main concepts used in the extreme programming methodology and their properties. XPO's modular structure was developed using the usual normative top down approach to software engineering process modeling. It relies on a set of core components rooted in three main concepts: organisational role, product and phase. Besides being useful for indexing relevant documents and XP artifacts such as user stories and Wiki pages, XPO is aimed at being a sound basis for nonintrusive analysis of agile processes, mining process data about programmers activity and repositories content in order to extract new concepts potentially identifying critical factors in agile software development. Extension to XPO are also discussed, including other agile methodologies and more general software engineering concepts.
Multiunit Normalized Cross Correlation Differs from the Average Single-Unit Normalized Correlation

As the technology for simultaneously recording from many brain locations becomes more available, more and more laboratories are measuring the cross-correlation between single-neuron spike trains, and between composite spike trains derived from several undiscriminated cells recorded on a single electrode (multiunit clusters). The relationship between single-unit correlations and multiunit cluster correlations has not yet been fully explored. We calculated the normalized cross-correlation (NCC) between single unit spike trains and between small clusters of units recorded in the rat somatosensory cortex. The NCC between small clusters of units was larger than the NCC between single units. To understand this result, we investigated the scaling of the NCC with the number of units in a cluster. Multiunit cross-correlation can be a more sensitive detector of neuronal relationship than single-unit cross-correlation. However, changes in multiunit cross-correlation are difficult to interpret uniquely because they depend on the number of cells recorded on each electrode and because they can arise from changes in the correlation between cells recorded on a single electrode or from changes in the correlation between cells recorded on two electrodes.
Constructing Topological Map from Metric Map Using Spectral Clustering

In large-scale environments, robots should have proper internal representation of the surroundings for achieving tasks such as localization, navigation, and exploration. Internal representations could be categorized in two ways: metric (grid-based) map and topological map. In this paper, we aim to generate a topological map representation (collision-free graph) of the large-scale environment from its metric map. The metric map is constructed by using laser range data with grid-line intersection algorithm. After metric map is obtained, spectral clustering is applied. Apart from the studies in literature, only the new cells obtained in a fixed time interval are employed in spectral clustering algorithm to avoid drawbacks of computational cost. Thus, the topological map grows incrementally in an online manner. In our work, we intended to represent the environment with as minimum as possible number of nodes. At the same time, the topological map must cover the entire environment. To do that, number of cluster is determined adaptively with respect to the number of new cells that can be combined in order to generate a cluster. Also, a simple heuristic is used for initialization of the k-means to avoid unrepeatable results. Lastly, obtained cluster centers are defined as nodes and they are connected to each other using minimum spanning tree algorithm. The proposed method is tested in ESOGU Electrical Engineering Laboratory building that is modelled in Gazebo simulation environment by using ROS. Experiments are conducted to demonstrate the performance of the proposed method.
Differentiating for Diversity: Using Universal Design for Learning in Elementary Computer Science Education

As computer science moves from an outreach activity to a normal classroom activity in the multi-subject, mainstream elementary school classroom, curricula need to be examined to ensure they are meeting the needs of diverse students. In this paper, we present how Universal Design for Learning (UDL) was used to develop and refine a programming environment and curriculum for upper-elementary school classrooms (students aged 9-12). We then present our accommodations and modifications to emphasize the ways our development environment and/or curriculum enabled such uses. Ensuring introductory computer science experiences are equitable and accessible for a wide range of student learners may broaden the diversity of individuals who perceive themselves as capable of pursuing computer science in the future.
Adherent bacteria in heavy metal contaminated marine sediments

Abstract The eubacterial communities adherent to sediment particles were studied in heavy metal contaminated coastal sediments. Six sampling sites on the Belgian continental plate and presenting various metal loads, granulometries, and organic matter content, were compared. The results indicated that the total microbial biomass (attached + free-living bacteria) was negatively correlated to HCl-extractable metal levels (p < 0.05) and that the percentage of cells adherent to sediment particles was close to 100% in every site even in highly contaminated sediments. Consequently, it seems that heavy metal contamination does affect total bacterial biomass in marine sediments but that the ratio between attached and free living microorganisms is not affected. The composition of the eubacterial communities adherent to the fine fraction of the sediments (<150 µm) was determined using fluorescent in situ hybridisation (FISH). The FISH results indicated that the proportion of γ- and δ-Proteobacteria, and Cytophaga-Flexibacter-Bacteroides (CFB) bacteria, was not related to the HCl extractable metal levels. Most of the 79 complete 16S rRNA sequences obtained from the attached microbial communities were classified in the γ- and δ-Proteobacteria and in the CFB bacteria. A large proportion of the attached γ-Proteobacterial sequences found in this study (56%) was included in the uncultivated GMS clades that are indigenous to marine sediments.
