Liposarcomas: diagnostic pitfalls and new insights

Liposarcomas represent the most common histotype among soft tissue sarcomas. However, liposarcomas in fact constitute a heterogeneous group of distinctive lesions that pose several diagnostic difficulties. The current World Health Organization classification of soft tissue and bone tumours recognizes four major liposarcoma subtypes: (i) atypical lipomatous tumour/well-differentiated liposarcoma; (ii) de-differentiated liposarcoma; (iii) myxoid liposarcoma; and (iv) pleomorphic liposarcoma. These four main subgroups are characterized by distinctive morphologies, unique genetic findings as well as distinct clinical behaviour. Accurate classification requires the integration of morphological, immunohistochemical and (in selected situations) genetic findings, and is essential for providing patients with the best available treatments. This review will focus upon the main diagnostic pitfalls encountered in the routine diagnosis of liposarcoma, underlining the diagnostic value of combining morphology with cytogenetics and molecular genetics.
Embedded data glyph technology for hardcopy digital documents

Bitmap printing from digital sources is commonly termed "digital printing"; however, machine retrieval of information content from printed images is typically inaccurate and unreliable in terms of digital information systems standards. For example, good optical character recognition systems provide error rates on the order of 1%. In another example, digital color copying, the loss of information compared to the original digital print file is much higher. Fundamentally, hardcopy printed for the needs of human readers does not provide a reliable digital data channel. In this sense these hardcopies are analog rather than digital documents. Embedded data technologies provide the means for encoding and retrieving digital information marked on hardcopy documents; they enable reliable information exchange between paper and electronic domains. A distinctive embedded data technology called self-clocking glyph codes has been developed by Xerox. Glyph codes provide digital data recording on hardcopy documents with high data density, robustness, pleasing appearance, and allowance for natural graphical integration with other printing. A good example of this code is composed of a rectangular lattice of mark centers with a linear or elliptical mark on each center oriented in one of two directions for recording one bit pei mark or one of four directions for recording two bits per mark. This code has the property of uniform visual texture and appears as a uniform gray or uniform color when printed at suitable scale compared to the viewing distance; for example, 5x5 pixel glyph cells at 300 dpi. Two-dimensional codes for data, synchronization, error correction, and other functions proide remarkable digital system robustness and functionality. Arbitrary digital data may be encoded to represent a vast variety of information. Examples include data representing visible printed content such as text files or color information and nonprinted document aspects such as formatting, revision histories, mathematical relations in spread sheets, and network file references. Thus, glyph codes provide high capacity digital data channels enabling document systems to bridge electronic and hardcopy domains with the functionality and reliability that users have come to expect of digital technologies. The format and appearance of glyph codes facilitate their graphical integration in documents. Together these features enable truly digital hardcopy documents that combine excellence in appearance and function.
Disstress in der Chirurgie – Eine Untersuchung in deutschen Krankenhäusern

Zusammenfassung Hintergrund Stress am Arbeitsplatz mit negativen Auswirkungen auf die Gesundheit (Disstress) ist gerade im Fachgebiet der Chirurgie weit verbreitet. Deswegen spielen die subjektiv wahrgenommenen Arbeitsbedingungen der Ärztinnen und Ärzte in der Chirurgie eine erhebliche Rolle für die eigene Gesundheit und die Gesundheit der Patienten. Wie die Arbeitsbedingungen im Fachgebiet der Chirurgie konkret wahrgenommen werden, soll durch die vorliegende Studie geklärt werden. Material und Methoden Diese webbasierte Studie, an der 1142 Ärzte und Ärztinnen der Chirurgie teilnahmen, stützt sich methodisch auf das Effort-Reward-Imbalance (ERI) Modell von Siegrist und das Job-Demand-Control Modell von Karasek. Der für diese Studie auf Basis der beiden Modelle konzipierte Fragebogen besteht aus Items zweier validierter und etablierter Fragebögen. Dadurch lässt sich eine Aussage über die Berufszufriedenheit und Disstress-Prävalenz im Fachgebiet der Chirurgie treffen. Ergebnisse In dieser Studie gaben 58,2% (95%-KI: 55,6 – 61,5) der Befragten ungünstige Arbeitsbedingungen in Form von Disstress (ER/JDC-Ratio > 1) an. Gleichzeitig war mit 52,2% (95%-KI: 49,3 – 55,1) ungefähr die Hälfte der Befragten sehr zufrieden mit ihrem Beruf. Bei Ärztinnen lag die Disstress-Prävalenz um 6 Prozentpunkte höher (95%-KI: 0,1 – 12,0) bei 62,4% und war damit signifikant höher als bei Ärzten (OR: 1,29; 95%-KI: 1,01 – 1,65; p < 0,05). In Betrachtung der in dieser Studie untersuchten 4 funktionalen Stellungen im Krankenhaus wiesen Chefärzte/-ärztinnen mit 22,0% die niedrigste Disstress-Prävalenz auf. Die höchste Disstress-Prävalenz wiesen Fachärzte mit 66,7% auf (OR: 7,11; 95%-KI: 3,26 – 15,48; p < 0,001). Weiterhin gaben 43,4% der befragten Fachärzte/-ärztinnen an, sehr zufrieden mit ihrem Beruf zu sein. Bei Oberärzten/-ärztinnen gaben dies 61,5% an (OR: 2,08; 95%-KI: 1,52 – 2,84; p < 0,001). Schlussfolgerungen Die dargestellten Daten unterstreichen ein hohes Stresspotenzial des Fachgebiets der Chirurgie in Bezug auf die Arbeitsbedingungen. Im Hinblick auf das Potenzial und Personal, welches durch eine Verbesserung der Arbeitsbedingungen im Fachgebiet der Chirurgie in den Kliniken gehalten werden könnte, sollte auf ein Gleichgewicht entsprechend des ERI/JDC-Modells geachtet werden.
Sequential learning neural network and its application in agriculture

We propose a sequential learning neural network (SLNN) and analyze the learning and recognition performances of the SLNN. The proposed SLNN consists of the bounded weight adjustment algorithm and structure adjustment method. Through many experiments, it turns out that our proposed SLNN can not only learn the knowledge of samples in series efficiently but also has fast learning speed. As an actual example of our network we have succeeded in applying our SLNN to Asian corn borer forecasting.
Simulation of medical decisions: Applications of SLN

Simulation has been applied to several important medical deci sion problems using the SLN language. The applications to end- stage renal disease, chronic stable angina, renal artery stenosis, and treatment of hypertension and hypercholesterolemia are reviewed emphasizing the modeling considerations and results. These investigations support the utility of simulation in medical decisions and the applicability of SLN to these problems. The general applicability of simulation to medical decision problems must be evaluated in the context of available knowledge and data. The simulation of medical decisions does not produce dependence among observations so prevalent in discrete-event simulations, but to the extent that arbitrary criteria such as cost- effectiveness are estimated, statistical concerns remain. Simula tion, particularly with SLN, can play an important role in medical protocol design.
Building an enterprise architecture step by step

For most organizations, getting started may be the hardest part of building an enterprise information technology architecture. One reason is that people have only a hazy idea of how to use a systematic architecting process to achieve specific goals. The entire idea of enterprise architecting seems grand and out of reach, so they feel more comfortable chipping away at it with patches. Unfortunately, these patches evolve to something only slightly more sophisticated. Some efforts never get that far. The architects get caught in a never-ending series of analyses and end up with nothing but a long to-do list just as the money runs out and the CEO expects to start seeing a return on investment. The article shows how to scope the project, set up the development team, and form a target architecture vision.
What Do Brain Data Really Show?

There is a bias in neuroscience toward localizing and modularizing brain functions. Single cell recording, imaging studies, and the study of neurological deficits all feed into the Gallian view that different brain areas do different things and the things being done are confined to particular processing streams. At the same time, there is a growing sentiment that brains probably don’t work like that after all; it is better to conceive of them as fundamentally distributed units, multi‐tasking at every level. This sentiment, however, is much less congenial to the tried‐and‐true experimental protocols available today and to theorizing about the brain in general. This essay examines the tension between current experimental methods and large‐scale views of the brain. We argue that this disconnection between experiment and what really are guiding theoretical metaphors seriously impedes progress in neuroscience.
Influence of Saccharomyces boulardii on the intestinal permeability of patients with Crohn's disease in remission

Objective. Crohn's disease (CD) is characterized by a reduction in mucosal integrity that permits antigen penetration into the intestinal tissue. The administration of probiotics has been suggested to improve the barrier function of the mucosa. The objective of this study was to evaluate the influence of Saccharomyces boulardii on the intestinal permeability in CD. Material and methods. Thirty-four patients were randomized according to the Vienna classification for treatment with either placebo or Saccharomyces boulardii. Baseline medications (mesalamine, azathioprine, prednisone, metronidazole and/or thalidomide) were maintained. Intestinal permeability (lactulose/mannitol ratio) was evaluated immediately before the beginning of treatment and at the end of the first and third treatment month. Fifteen healthy volunteers were also submitted for the intestinal permeability test. Results. In volunteers, the lactulose/mannitol ratio was 0.005±0.0037, whereas this value was 0.021±0.01 in patients with CD (p=0.
‘Private path, public route’: a multicultural group of teachers experiences Wiki-assisted learning

This qualitative study examined how a multicultural group of experienced teachers (nine Arabs, ten Jews) used Wiki as an alternative platform for the construction of a shared interpretive knowledge base. None of the participants had had any prior experience with Wiki as a learning environment. Data were derived from the Wiki platform, teachers’ oral and written feedback, and the lecturer’s log. Generally, teachers expressed positive attitude towards learning in a Wiki environment. However, cultural differences relating to language, habitual ways of studying and evaluating, and perceptions of teacher–student roles in classrooms affected participation. Different ways of using Wiki were observed along a continuum from teachers’ adaptation of Wiki to learners’ characteristics to learners’ adaptation of selves to Wiki characteristics. The findings may alert teacher educators to ways of integrating Wiki pedagogy into teachers’ curricular thinking: an explicit discussion of Wiki pedagogy attributes; more than one experience with long-term Wiki projects; supportive and sharing environment; attention to language barriers; a constant presence of the lecturer in the ‘discussion boards’ to guide and share concerns.

Extracción y normalización de entidades genómicas en textos biomédicos: una propuesta basada en transductores gráficos

The lack of systems endorsed to call the genes is a problem for the identification of information in the biomedical literature and does very difficult an essential process in the field of the molecular biology: finding and to discover biological relations among genes, in those documents that treat the same genomic entity but that they use different symbols. We propose a procedure taken from the of natural language processing (NLP) based on the application of transducers of finite-state that allows the recognition of the diverse names of a gene and relates them to an unified form. The process of standardization requires as input a list of synonyms, and as an output an unique identifier for that gene. The genomic database FlyBase has contributed us the necessary resources to expose our proposal.
Comparison of Optical and Electronic 3-Dimensional Circuits

Optical and 3D electronic implementations of a rearrangeably non-blocking permutation network are compared using complexity models. The electronic complexity model is based on the Thompson model for VLSI while the optical complexity model is new and based on the characteristics of optoelectronic devices and holographic optical elements. The analysis holds the manufacturing cost size and BER of the two implementations equal while comparing their latency. Whether optics is better than electronics depends on the message length. © (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.

Design, Modeling and Implementation of Pic Based Wireless Control System to Eliminate Blind Spots in Vehicle Side Mirrors

A PIC controlled IR system for the control of vehicle side mirror system movements for the purpose of revealing blind spots is designed and implemented. The designed and built system allows the side view mirrors to be adjusted based on the driver head movement. The infrared-based head tracking system maps a predetermined coordinates for head movements and results in a triangularly computable geometry, which is fed to the PIC, based controlling system. This will cause the vehicle mirror movement via carefully selected miniature motors.
Energy-Performance Tunable Logic

We propose a new logic family that enables the user to tune the transistor's effective threshold voltage after fabrication for higher speed or lower power. This technique along with dynamic voltage scaling allows simultaneous optimization of static and dynamic power based on the application/workload requirements. Programmable interconnect from an FPGA was implemented using this logic family on a 90 nm CMOS test chip. Measurements show that this topology provides twice the tuning range in the energy-performance space compared to a conventional interconnect utilizing only supply voltage scaling. For most of the performance range, this circuit consumes 35% less energy compared to a state-of-the-art design. The circuit is an externally static, internally pulse-mode topology which can replace static circuits without requiring significant changes to the system.
MARank: Algorithm of Microblogging Propagation's Node Influence Evaluation Based on User Authentication

In resent years,the data mining and analysis of the microblogging has been a hot spot with its vigorous development.In its propagation process, the users’ ranking is generally arranged in out-degree, which cannot reflect the potential forwarding possibility of micro-blogs.To solve this problem, PageRank algorithm was used to present the algorithm of microblogging propagation node influence evaluation based on user authentication,which enables us effectively predict the future ranking of users’ nodes and shows some practical value.
Parallel block inversion of geophysical data

We present an automatic blocking algorithm for some medium size nonlinear least squares problems that arise in the inversion of travel time data in geophysics. This blocking leads to a nonlinear Gauss-Seidel type iteration which can be distributed to a network of computers. The low dimensional blocks are also amenable to global optimization methods which leads to further parallelization. All this is necessary because the original problem is generally non- convex, ill-conditioned, with a goal functional that is very expensive to evaluate.
Integrated echo and noise canceler for hands-free applications

An integrated acoustic echo and noise canceler is proposed for hands-free telephony applications. The proposed system includes a computationally efficient double-talk detection (DTD) method and a residual echo cancellation algorithm. The DTD method uses two cross-correlation coefficients and is robust in adverse conditions. In the residual echo cancellation approach, a linear prediction error filter removes the short-term correlation of the residual echo and the resulting whitened residual echo is canceled by a noise-reduction filter. The proposed system was implemented using a general purpose digital signal processor (DSP) with 16-b arithmetic.
An Adaptive Bilateral Filter for Noise Removal and Novel Hybrid Fuzzy Cognitive Map-FNN Edge Detection Method for Images

The important process in image processing is edge detection and it is considered as the basis for the pattern recognition owing to its effect on the subsequent processes of image processing. Edge detection is highly needed for processing of noisy images as noise is the main shortcoming of the images. There are many optimization algorithms such as SVM, WSVM classifiers so far reported for performing edge detection. Inspire of rendering better results, these existing methods suffer from lack of transparency thus affecting the overall performance of the system. This paper presents a novel method for edge detection which operates on the hybrid fuzzy cognitive map based fuzzy neural network (HFCM-FNN). This method employs a facile way of processing images using HFCM-FNN by reducing the execution time and upgrading the visual quality. The experimentation results shows the overall performance results of the proposed HFCM-FNN edge detection method and it can be compared with existing SVM, WSVM methods.
Fast Secure Virtualization for the ARM Platform

In recent years, powerful handheld computing devices such as personal digital assistants and mobile smart phones have become ubiquitous in home and office environments. Advancements in handheld device hardware have driven the development of the software that runs on them. As these devices become more powerful, increasingly connected, and the tasks performed by their operating systems more complex there is a need for virtual machine monitors. Virtual machine monitors such as the Xen hypervisor developed at the University of Cambridge could bring an increased level of security to handheld devices by using resource isolation to protect hosted operating systems. VMMs could also be used to place constraints on the resource utilization of hosted operating systems and their applications. Xen is closely tied to the x86 computer architecture and is optimized to work well on desktop personal computers. One of its design goals was to provide virtualization on x86 computers similar to that which was previously found only on IBM mainframes designed to support virtualization. We aim to provide this same style of virtualization on mobile devices, the majority of which are powered by the ARM computer architecture. The ARM architecture differs considerably from the x86 architecture. ARM was designed with high performance, small die size, low power consumption, and tight code density in mind. By migrating Xen to the ARM architecture, we are interested in gaining insight into the capacity of ARM powered devices to support virtual machines. Furthermore, we want to know which of the StrongARM’s architectural features help or hinder the support of a Xen-style paravirtualization interface and whether guest operating systems will be able to run without modification on top of a StrongARM based hypervisor. In this thesis, we describe the design and implementation issues encountered while porting the Xen hypervisor to the StrongARM architecture. The implementation of a prototype has been carried out for SA-110 StrongARM processor and is based on the hypervisor in Xen version 1.2.
