An implementation of end-to-end controlled streaming system using similarity-based frame discarding approach on DiffServ

Video streaming technology has been widely used for various Internet services. In this paper, we present an implementation strategy of video streaming systems under end-to-end traffic controls, and we adapt this system to fit into the differentiated services (DiffServ) architecture. Unlike other previous works, we suggest that an end-to-end controlled streaming system is viable and easily deployed without any adaptation to core network routers. We will present experimental results to illustrate the effectiveness of our proposed system.
How can group‐based multidisciplinary rehabilitation for patients with fibromyalgia influence patients' self‐efficacy and ability to cope with their illness: a grounded theory approach

AIMS AND OBJECTIVES To describe how group-based multidisciplinary rehabilitation for patients with fibromyalgia can influence patients' self-efficacy and ability to cope with their illness. BACKGROUND Multidisciplinary rehabilitation is recommended in the management of fibromyalgia. Self-efficacy is said to influence and predict adaptive coping behaviours and functioning. However, knowledge is lacking on how rehabilitation programmes may influence self-efficacy and ability to cope, from the patients' perspective. DESIGN Grounded theory study of semi-structured focus group interviews. METHODS Participants (n = 17) were included in four focus groups that had completed a two-week multidisciplinary rehabilitation programme together. Interviews were conducted four weeks after each group had completed the programme. The analysis was conducted constant comparatively applying open, axial and selective coding. RESULTS Categories (in italics) were derived from data in which the explanatory core category was identified: Learning to accept and live with pain as a life condition, and linked to three categories mutually influencing each other: Increased self-acceptance of living with the illness, experiencing acceptance from others and developing new coping strategies. Thus, patients benefitted from multidisciplinary rehabilitation with stronger self-efficacy and expectations to their future coping. However, limitations in the programme were identified, as the programme was short and intensive with no subsequent follow-up, and social welfare was not sufficiently addressed. Participants also found it difficult to maintain knowledge and were lacking individual sessions with the psychologist and had waited long to receive rehabilitation. CONCLUSION Multidisciplinary rehabilitation may advantageously be offered to patients with fibromyalgia. However, earlier action with longer programmes, in which patients' social situation is addressed, comprising individual sessions with the psychologist, with multiple repetitions of the content and follow-up sessions, may further enhance the patients' self-efficacy and coping with their illness.
Construction of orthogonal CC-sets

In this paper we present a graph-theoretical method for computing the maximum orthogonal subset of a set of coiled-coil peptides. In chemistry, an orthogonal set of peptides is defined as a set of pairs of peptides, where the paired peptides interact only mutually and not with any other peptide from any other pair. The main method used is a reduction to the maximum independent set problem. Then we use a relatively well-known maximum independent set solving algorithm which turned out to be the best suited for our problem. We obtained an orthogonal set consisting of 29 peptides (homodimeric and heterodimeric) from initial 5-heptade set. If we allow only heterodimeric interactions we obtain an orthogonal set of 26 peptides.
A study on searching and recommending SCORM CPs by ontological support

The purpose of this study is to implement content packages of searching and recommending for teachers while they intend to deliver a specified course unit. Many efforts have been made on how to technically develop authoring tools instead how to apply existing content packages in teaching practices. To overcome these barriers, this study proposes an ontology approach as teachers' perspective to fully exploit the implicit metadata in manifest.xml. The implementation tool consists of Protegee 2000, Jena API, and Java script. Firstly, the parser of Natural language Understanding can accept the Mandarin in GUI and transform it into an index of competence (IC) from domain ontology. Then, task ontology can be attained with a CP. Secondly, the application ontology is defined as learning sequences of different CPs. Thus, it guides scaffolding for extensible or remedial CPs for teachers' instructional design. Finally, the implications of this study and future research are also included.
Fiducials: Achilles' heel of image-guided neurosurgery: an attempt at indigenization and improvement.

Image-guided surgery or neuronavigation has become an important part of the neurosurgical armamentarium in most centers around the world, primarily because it helps to improve patient safety and consistency of surgical results.1–5,8 However, these advantages come at the cost of increased health care and patient expenses. The disposable products used in image-guided surgery are often very costly. In developing countries such as India, hospitals may find money for large capital purchases, but often fail to budget for the price of consumables over the lifetime of the product. The lack of availability of the consumables may lead to underuse of the equipment. At the All India Institute for Medical Sciences, the Medtronic StealthStation (Medtronic Sofamor Danek, Inc., Memphis, TN) is used for neuronavigation, and the disposable fiducials cost INR4200 (US$100) for every procedure in which the StealthStation is used. As the average cost of consumables in major cranial surgery at our center is INR15000 (US$350), using neuronavigation can increase these costs by 25% simply because of the cost of fiducials. We therefore attempted to find less expensive available indigenous alternatives to replace the proprietary fiducials used with the StealthStation in image-guided neurosurgery.
The dynamic cuckoo filter

The emergence of large-scale dynamic sets in real applications creates stringent requirements for approximate set representation structures: 1) the capacity of the set representation structures should support flexibly extending or reducing to cope with dynamically changing of set size; 2) the set representation structures should support reliable delete operation. Existing techniques for approximate set representation, e.g., the cuckoo filter, the Bloom filter and its variants cannot meet both the requirements of a dynamic set. To solve the problem, in this paper we propose the dynamic cuckoo filter (DCF) to support reliable delete operation and elastic capacity for dynamic set representation and membership testing. Two factors contribute to the efficiency of the DCF design. First, the data structure of a DCF is extendable, making the representation of a dynamic set space efficient. Second, a DCF utilizes a monopolistic fingerprint for representing an item and guarantees reliable delete operation. Experiment results show that compared to the existing state-of-the-art designs, DCF achieves 75% reduction in memory cost, 50% improvement in construction speed, and 80% improvement in speed of membership query. We implement a prototype file backup system and use DCF for data deduplication. Comprehensive experiment results demonstrate the efficiency of our DCF design compared to existing schemes.
Text Retrieval for Japanese Historical Documents by Image Generation

Digitization of historical documents is growing rapidly. Text retrieval is a vital technology to facilitate the use of historical document images because of the large amount of data. In this paper, we propose a method for retrieving keywords in Japanese historical documents with text query. The proposed method automatically generates an image of the query text and retrieves regions in documents similar to the generated image by feature matching. We exploit a technique of deep learning to generate an image close to texts in Japanese historical document images. Furthermore, we use convolutional neural network to extract features robust to appearance variation of texts in documents, such as shade and shape of texts. We conducted the text retrieval experiments on the public dataset of Japanese historical documents in the Edo era. The experimental results show the effectiveness of the proposed method.
Analytical solution of the bioheat equation for thermal response induced by any electrode array in anisotropic tissues with arbitrary shapes containing multiple-tumor nodules

The Pennes bioheat transfer equation is the most used model to calculate the temperature induced in a tumor when physical therapies like electrochemical treatment, electrochemotherapy and/or radiofrequency are applied. In this work, a modification of the Pennes bioheat equation to study the temperature distribution induced by any electrode array in an anisotropic tissue containing several nodules (primary or metastatic) with arbitrary shape is proposed. For this, the Green functions approach is generalized to include boundaries among two or more media. The analytical solution we obtain in a very compact way, under quite general suppositions, allows calculating the temperature distributions in the tumor volumes and their surfaces, in terms of heat sources, initial temperature and calorific sources at the boundary of tumors.
Overtreatment with inhaled corticosteroids and diagnostic problems in primary care patients, an exploratory study.

BACKGROUND Underdiagnosis and undertreatment of patients with asthma or chronic obstructive pulmonary disease are widely discussed in the literature. Not much is known about the possible overdiagnosis and consequently the overtreatment with inhaled corticosteroids (ICS). Aim. This study investigates how often ICS are prescribed without a proper indication and how big the diagnostic problem is caused by inappropriate prescription and use of ICS. METHODS All patients referred to a primary care diagnostic centre during 6 months who used ICS without a clear indication were included. Their GPs were questioned about the reasons for prescribing ICS. If still no diagnosis could be assessed, GPs were advised to stop ICS and renew spirometry after a steroid-free period of at least 3 months. After 1 year, the use of ICS was evaluated and the diagnoses were reassessed. RESULTS Of all referred patients (2271), 1171 used ICS, 505 (30%) without a clear indication. After 1 year, final results showed that 11% of all patients originally using ICS had no indication to use ICS and had successfully ceased using this mediation. For 15%, the reasons for using ICS remained unclear. CONCLUSIONS Overtreatment with ICS in primary care seems to be considerable, which falsely labels patients as asthmatic and which generates unnecessary costs and possible side effects. The awareness of GPs of the need for proper diagnostic testing before prescribing ICS needs to be improved. Overtreatment with ICS in primary care patients can be diminished by systematically supporting the GP in the diagnostic procedures and decision making.
Modeling Heat Conduction in Spiral Geometries

The spirally wound design is of importance to battery manufacturers as it improves the energy and power densities, by using lesser accessories when compared with the prismatic design. 1-2 For this reason, the spirally-wound design is used in a variety of battery systems ~e.g., Li-SOCl2 , 3 Li bromine chloride complexing additive ~BCX! , 4 lead-acid, 5 Zn-MnO2 , 6 Li-ion 1-2,7 ! However, because of their lower surface area to volume ratio, spiral batteries retain more heat than prismatic batteries. Therefore, in order to improve thermal management and achieve safe operation of large-scale spirally wound batteries, it is important to understand their thermal behavior, especially during high rate operation. A cost effective method of studying heat transport during the operation of a battery is to theoretically simulate the temperatures attained by the battery. However, very few publications 3-9 exist in the literature that couple electrochemical and thermal behavior in spirally wound batteries. Rather, most thermal models of spirally wound batteries estimate the heat generation rate a priori from experimental voltage-time data. 3-4,7-9 Cho and Halpert 8 and Cho 9 assumed that the entire battery operates at a uniform temperature, while Al Hallaj et al. 7 simulated a 1-D radial variation in temperature. Evans and White 3 and Kalu and White 4 accounted for both radial and spiral heat conductions in their spirally wound battery systems using a two-dimensional ~2-D! model for the energy balance. Evans and White 3 compared the predictions of the 2-D model
Einmal unten – immer unten? Empirische Befunde zur Lohn- und Einkommensmobilität in Deutschland

Die Debatte um die Verteilungsgerechtigkeit wird bisweilen mit groser Scharfe gefuhrt. Darin spielen traditionell Indikatoren zur Ungleichheit eine grose Rolle, die in der Regel nur eine Momentaufnahme liefern. Allerdings durfen auch Kennzahlen zur sozialen Mobilitat nicht auser Acht gelassen werden. Wenn Chancen auf einen sozialen Aufstieg vorhanden sind, konnen grosere Ungleichheiten als weniger problematisch bewertet werden. Dies gilt vor allem fur den Aufstieg aus den unteren Schichten. Empirische Befunde auf Basis des Sozio-oekonomischen Panels zeigen, dass Aufstiegschancen aus dem Niedriglohnsektor vorhanden sind. Immerhin gut ein Viertel der Geringverdiener schafft den Sprung uber die Niedriglohnschwelle. Wahrend im Zeitverlauf der Anteil der Aufsteiger bis etwa zum Jahr 2008 tendenziell rucklaufig war, zeichnet sich seitdem ein leicht steigender Trend ab. In Bezug auf die Einkommensmobilitat, bei der neben dem Erwerbseinkommen weitere Komponenten des Haushaltseinkommens berucksichtigt sind, kann rund ein Drittel der armutsgefahrdeten Personen innerhalb eines Jahres aus der untersten Einkommensschicht aufsteigen. In einem Zeitraum von zehn Jahren sind es sogar 58 Prozent. Indes ist fur die Einkommensmobilitat keine positive Entwicklung in der Aufstiegshaufigkeit zu erkennen. Zusammenfassend hat sich die soziale Mobilitat im Zeitverlauf kaum verbessert. Insofern sollte erstens beobachtet werden, wie sich etwa vor dem Hintergrund der Fluchtlingsmigration oder der Einfuhrung des Mindestlohns die Mobilitat zukunftig entwickelt. Zweitens besteht weiterer Forschungsbedarf hinsichtlich der Grunde fur die beobachtete Entwicklung.
Excision and transfer of the Mesorhizobium loti R7A symbiosis island requires an integrase IntS, a novel recombination directionality factor RdfS, and a putative relaxase RlxS

The Mesorhizobium loti strain R7A symbiosis island is an Integrative Conjugative Element (ICE), herein termed ICEMlSymR7A, which integrates into a phetRNA gene. Integration reconstructs the phetRNA gene at one junction with the core chromosome, and a direct repeat of the 3‐prime 17 bp of the gene is formed at the other junction. We show that the ICEMlSymR7AintS gene, which encodes an integrase of the phage P4 family, is required for integration and excision of the island. Excision also depended on a novel recombination directionality factor encoded by msi109 (rdfS). Constitutive expression of rdfS resulted in curing of ICEMlSymR7A. The rdfS gene is part of an operon with genes required for conjugative transfer, allowing co‐ordinate regulation of ICEMlSymR7A excision and transfer. The excised form of ICEMlSymR7A was detectable during exponential growth but occurred at higher frequency during stationary phase. ICEMlSymR7A encodes homologues of the traR and traI genes of Agrobacterium tumefaciens that regulate Ti plasmid transfer via quorum sensing. The presence of a plasmid with cloned island traR traI2 genes resulted in excision of ICEMlSymR7A in all cells regardless of culture density, indicating that excision may be similarly regulated. Maintenance of ICEMlSymR7A in these cells depended on msi106 (rlxS) that encodes a putative relaxase. Transfer of the island to non‐symbiotic mesorhizobia required intS, rlxS and rdfS. The rdfS and rlxS genes are conserved across a diverse range of α‐, β‐ and γ‐proteobacteria and identify a large family of genomic islands with a common transfer mechanism.
The Unbearable Stability of the German Wage Structure: Evidence and Interpretation

This paper uses micro data from the German Socio-Economic Panel to document that the wage structure in West Germany was remarkably stable over the period 1984-97, with little variation over time in wage or earnings inequality among and within different skill groups. The paper investigates a number of possible explanations for the stability of the wage structure and concludes that it is attributable to institutional factors rather than market forces. Consequently, the rigidity of relative wages despite relative shifts in labor demand that favor skilled workers has resulted in sharp declines in employment rates for unskilled workers. The micro evidence is also shown to have important implications for interpreting trends in wage shares, capital-labor ratios, and aggregate unemployment.
Transcriptional activation of a pap pilus virulence operon from uropathogenic Escherichia coli.

A gene cluster mediating production of pili in uropathogenic Escherichia coli was analysed with respect to regulation of pili synthesis. Two cistrons, papB and papI, were localized upstream of the major pilus subunit gene, papA. The papI‐papB‐papA region was characterized by nucleotide sequencing and by transcriptional analysis. The papA gene was primarily represented by an 800 nucleotide long transcript but was also co‐transcribed with papB as a less abundant 1300 nucleotide long mRNA. Both transcripts presumably terminated at the same site downstream of the papA coding sequence. The weakly expressed papI gene was transcribed in the opposite direction to that of papB and papA. Studies with lacZ operon fusions showed that the papB gene encoded a trans‐active effector required for papA transcription. Similarly, the papI gene stimulated papB transcription in trans. Furthermore, full expression of papA was cis dependent upon the papI‐papB region. Transcription of the papB gene was shown to be dependent upon cAMP and its receptor protein. A binding site for the cAMP‐CRP complex was postulated in the DNA sequence upstream of the papB promoter.
Electron Microscopy of Tissue Cultures Infected with the Virus of Eastern Equine Encephalomyelitis.∗

During the past 2 years we have been studying the growth of several viruses in tissue culture with particular emphasis on the use of the electron microscope. The cellular destruction and overwhelming growth of the virus of eastern equine encephalomyelitis are here reported. Successful electron microscopy of virus infected cells has been limited to studies on “virus induced” tumors 1 , 2 and has not been applied to small rapidly multiplying viruses. Our technic is essentially that of Porter 3 except that cells are usually fixed for only ten minutes with osmic acid vapor. 4 Chick embryo tissue was cultured for 6 days with one transfer in roller tubes 5 in a completely homologous medium composed of chicken plasma and serum and chick embryo extract. Pieces of this tissue were then exposed to a 10-2 dilution of the virus. A saline extract of embryos infected with the fourth embryo passage of a standard guinea pig passage of eastern equine encephalomyelitis was used as source of virus. This tissue explant was then placed in a special chamber. This was formed by drilling the center out of a metal plate and sandwiching it between 2 formvar coated glass slides. The medium consisted of 20% chicken serum. Within the next 24 hours of incubation at a temperature of 37°C, the cells had grown out poorly and were already beginning to be destroyed. The cells were fixed by exposure to osmic acid vapor and were either examined directly or were first coated with chromium to sharpen the image. The fluid taken from the tissue culture chamber taken just before osmic acid fixation of the preparation shows a high titer of infectivity for the chick embryo.

Efficient 3D correspondence grouping by two-stage filtering

This paper presents an efficient 3D correspondence grouping algorithm for finding inliers from an initial set of feature matches. The novelty of our approach lies in the use of a combination of pair-wise and triple-wise geometric constraints to filter the outliers from the initial correspondence. The triple-wise geometric constraint is built by considering three pairs of corresponding points simultaneously. A global reference point generated according to the model shape can be mapped to the scene shape thereby form a derived point by the triple-wise geometric constraint. Then, all the initial correspondence can be filtered once via the global reference point and the derived point by using some simple and low-level geometric constraints. Afterwards, the remaining correspondences will be further filtered by means of the pair-wise geometric consistency algorithm. Finally, more accurate matching results can be obtained. The experimental results show the superior performance of our approach with respect to the noise, point density variation and partial overlap. Our algorithm strikes a good balance between accuracy and speed.
Hypnosis: state of the art and perspectives for the twenty‐first century

In this presidential lecture research evidence is addressed for the effectiveness of clinical hypnosis as a psychotherapeutic and medical healing method. The state of the art is characterized by meta-analyses indicating the usefulness and effectiveness of clinical hypnosis and by neuroimaging data indicating hypnotic trance exists as a separate state of consciousness. Hypnosis research can profit from mainstream psychological research as well as inspire it by putting the research focus on the underlying processes of communication, rapport, attention and perception. In future developments, hypnosis is also seen as the home-base for research and the therapeutic usage of suggestions. A new paradigm for pharmaceutical research is envisioned in which efforts to maximize substance-effects by proper suggestive communication are to be enhanced, once the effectiveness of the medical drug has been demonstrated.
