Performance of greedy policies for downlink scheduling in networks with relay stations

: We investigate a greedy policy for delay-optimal scheduling in broadband wireless networks using relay stations (RS). The key idea behind the policy is that users should greedily exploit op-portunism from time varying channels, while the basestation should prioritize balancing queues at RS. A ﬂuid model is presented to show that such policy is optimal in the ﬂuid regime. By simulation we show that the proposed scheme reduces mean delay by up to 73% compared to backpressure algorithm.
Histopathology of the red lunula: new histologic features and clinical correlations of a rare type of erythronychia

The lunula is the semi‐lunar shaped area seen at the proximal aspect of the nail unit. It is the most distal aspect of the nail matrix that can be visualized through the transparent nail plate. The term red lunula describes erythema that partially or completely replaces the normal white color of the lunula. Red lunulae have been associated with a number of dermatologic and systemic conditions. However, the etiology and histopathology of the red lunula have not been characterized. We report a case of red lunulae of the fingernails in an adult male. Histopathologic examination revealed an increased density of benign‐appearing and mildly dilated vascular channels present in the superficial papillary dermis of the nail matrix. To our knowledge, this is the first report of distinct pathologic findings seen on histologic examination of a red lunula. The increased vascularity of the lunula seen microscopically correlates with the clinically observed red color. These findings raise the possibility that systemic or local factors are responsible for angiogenesis within the nail unit in disorders associated with the red lunula.
Naturally acquired human immune responses againstHelicobacter pylori and implications for vaccine development

Helicobacter pylori has been identified as a causative agent of gastroduodenal pathology. Vaccination studies with mouse models have shown that immunisation with bacterial antigens can provide protection against infection, indicating that it may be possible to design vaccines which terminate colonisation by H pylori or prevent it from taking place. Here, we review critically current knowledge of naturally acquired human humoral and cellular immune responses to H pylori with the aim of delineating questions which should be tackled in order to permit a rational and directed approach to the development of an effective vaccine. We have also reviewed the literature and identified candidate vaccine antigens. H pylori is a Gram negative flagellated bacterium which lives both in the mucus gel layer that coats the gastric mucosa and between the mucus gel layer and the apical surfaces of gastric mucosal epithelial cells. Although it seems to be largely extracellular, some invasion of gastric cells has been reported.1 In Western countries, H pylori infection increases from a low prevalence in childhood to about 20% of people below 40 years of age,2 with a steep rise in infection rates to 50% at age 60, attributed to increased infection during the Second World War. In underdeveloped countries, acquisition of infection occurs in 10% of children per annum so that 90% are infected by their teenage years. There is a strong association between gastric H pylori infection and gastroduodenal disease.3 The presence of the bacterium invariably causes the surrounding mucosa to become inflamed,3-5 and the degree of gastritis present is positively correlated with the extent of H pylori colonisation.3 6 Although most people infected with H pylori remain asymptomatic, in some the gastritis progresses to more severe forms of gastroduodenal pathology. Atrophy, characterised by distortion and destruction of the glands, …
Large-scale Kernel RankSVM

Learning to rank is an important task for recommendation systems, online advertisement and web search. Among those learning to rank methods, rankSVM is a widely used model. Both linear and nonlinear (kernel) rankSVM have been extensively studied, but the lengthy training time of kernel rankSVM remains a challenging issue. In this paper, after discussing difficulties of training kernel rankSVM, we propose an efficient method to handle these problems. The idea is to reduce the number of variables from quadratic to linear with respect to the number of training instances, and efficiently evaluate the pairwise losses. Our setting is applicable to a variety of loss functions. Further, general optimization methods can be easily applied to solve the reformulated problem. Implementation issues are also carefully considered. Experiments show that our method is faster than state-of-the-art methods for training kernel rankSVM.
Volume of Foremilk, Hindmilk, and Total Milk Produced by Mothers of Very Preterm Infants Born at Less Than 28 Weeks of Gestation

The purpose of this study is to describe foremilk volume (milk produced in the first 3 minutes of pumping), hindmilk volume (remainder of milk produced), and total milk volume produced by mothers of very preterm infants at 3 weeks postpartum and associated factors. Mothers (n = 24) mechanically pump their breasts a median (minimum, maximum) of 7 times (5, 9 times) per 24 hours for a total of 15 minutes (9.4, 23.9 minutes) each time. Foremilk, hindmilk, and total milk volumes are 183 mL per 24 hours (80, 810), 318 mL per 24 hours (98, 1007), and 545 mL per 24 hours (224, 1817), respectively. Milk volumes are not associated with mother's age, race or ethnic background, education, parity, reported prepregnancy body mass index, previous breastfeeding experience, frequency of milk pumping, longest time between pumps, infant birth weight, or multiple births. The degree of pre-maturity (<26 weeks vs 260/7-276/7 weeks) is significantly related to the relative proportion of foremilk/hindmilk volumes (45:55 vs 36:65, respectively). J Hum Lact. 25(3):272-279.
A conceptual design tool to facilitate simulation model development: Object flow diagram

This paper describes a diagramming methodology, referred to as an Object Flow Diagram (OFD), that is intended to be a key component in the conceptual design of a discrete-event simulation model. It provides an effective means for representing salient system elements and their relationships. It draws upon other popular system diagramming methods, such as IDEF0 and IDEF3, to bring the relevant aspects of these tools to the simulation modeler. It is intended to be easy to apply, with few symbols and constructs, yet robust and comprehensive enough to represent a wide variety of systems. It is simulation software neutral and thus provides a basis for model development in any language. A simple example is used to illustrate the approach. The methodology has been used in industry projects and in simulation courses.
Implementation of a Guideline for Low Back Pain Management in Primary Care: A Cost-Effectiveness Analysis

Study Design. Cost-effectiveness analysis alongside a cluster randomized controlled trial. Objective. To study the cost-effectiveness of 2 low back pain guideline implementation (GI) strategies. Summary of Background Data. Several evidence-based guidelines on management of low back pain have been published. However, there is still no consensus on the effective implementation strategy. Especially studies on the economic impact of different implementation strategies are lacking. Methods. This analysis was performed alongside a cluster randomized controlled trial on the effectiveness of 2 GI strategies (physician education alone [GI] or physician education in combination with motivational counseling [MC] by practice nurses)-–both compared with the postal dissemination of the guideline (control group, C). Sociodemographic data, pain characteristics, and cost data were collected by interview at baseline and after 6 and 12 months. low back pain–related health care costs were valued for 2004 from the societal perspective. Results. For the cost analysis, 1322 patients from 126 general practices were included. Both interventions showed lower direct and indirect costs as well as better patient outcomes during follow-up compared with controls. In addition, both intervention arms showed superiority of cost-effectiveness to C. The effects attenuated when adjusting for differences of health care utilization prior to patient recruitment and for clustering of data. Conclusion. Trends in cost-effectiveness are visible but need to be confirmed in future studies. Researchers performing cost-evaluation studies should test for baseline imbalances of health care utilization data instead of judging on the randomization success by reviewing non-cost parameters like clinical data alone.
Adaptive learning region importance for region-based image retrieval

This study addresses the issue of region representation in region-based image retrieval (RBIR). In order to reduce the user's burden of selecting the region of interest, a statistical index called visual region importance (RI) is constructed to describe the region. By learning from user's current and historical feedback information, visual RI can be automatically updated and semantic RI can be obtained. Furthermore, adaptive learning RI and memory learning RI (MLRI) techniques for RBIR system have been presented. Specifically, the MLRI can mitigate the negative influence of interference regions well. Extensive experiments on the Corel-1000 dataset and the Caltech-256 dataset demonstrate that the proposed frameworks are effective, are robust and achieve significantly better performance than the other existing methods.
Towards automatic imperative program synthesis through proof planning

An approach to automatic imperative program synthesis is presented which builds upon Gries' (1981) vision of developing a program and its proof hand in hand. To achieve this vision we rely on the proof planning paradigm, which enables the coupling of both heuristic and deductive components. By formalising structured programming and proof heuristics within the proof planning framework we focus the search for a correct program. Encoding these heuristics within a proof plan and strengthening proof planning, by embedding it within the conventional AI planning paradigm, enables a significant degree of automation.
Treatment of food anaphylaxis with traditional Chinese herbal remedies: from mouse model to human clinical trials

Purpose of reviewTo describe the development of a novel treatment for food allergy, named the food allergy herbal formula-2 (FAHF-2), that is based on traditional Chinese medicine. Recent findingsFAHF-2 has proven to be well tolerated and effective for the treatment of food allergies in murine models of peanut and multiple food allergies. These results are accompanied by evidence of favorable immune modulation, and the effects are persistent after the discontinuation of treatment. Early clinical trials demonstrate the safety and tolerability of this formula in individuals with food allergies. An ongoing Phase II clinical trial will evaluate the efficacy of FAHF-2 in protecting individuals from allergen-induced allergic reactions during oral food challenges. SummaryFAHF-2 is an herbal formula that has a high safety profile and has shown to prevent anaphylaxis in murine models of food allergy. Similar findings in clinical trials could bring a novel treatment for food allergies.
Biochemical insight into the prion protein family

Prion protein family comprises proteins, which share not only similarity in their primary structure, but also similarity in their fold. These two groups of similarity presume a parceling in their respective biological function through the common biochemical properties. In this review, biochemical and structural similarities of PrP and two other proteins, Doppel and Shadoo, are evocated. Some evidence demonstrating respectively similarity between PrP N-terminal and C-terminal domain with respectively Shadoo and Doppel is presented. We extended primary structure similarity analysis to the other PrP subdomain as 166-176 polyNQ domain and compare it to proteins using aggregation as a support for structural information transference and structural epigenetic. Finally, we questioned if prion protein family have conserved the PrP structural bistability, which should be at the origin of Prion phenomenon and if Prion pathology is not, ultimately, an exaptation of the physiological propensity of PrP to undergo a structural switch and polymerize.

Pict: a programming language based on the Pi-Calculus

The -calculus o ers an attractive basis for concurrent programming. It is small, elegant, and well studied, and supports (via simple encodings) a wide range of high-level constructs including data structures, higher-order functional programming, concurrent control structures, and objects. Moreover, familiar type systems for the -calculus have direct counterparts in the -calculus, yielding strong, static typing for a high-level language using the -calculus as its core. This paper describes Pict, a strongly-typed concurrent programming language constructed in terms of an explicitly-typed -calculus core language. Dedicated to Robin Milner on the occasion of his 60th birthday.
Trivariate B-spline Approximation of Spherical Solid Objects

—Recently, novel application areas in digital geometry processing, such as simulation, dynamics, and medical surgery simulations, have necessitated the representation of not only the surface data but also the interior volume data of a given 3D object. In this paper, we present an efficient framework for the shape approximations of spherical solid objects based on trivariate B-splines. To do this, we first constructed a smooth correspondence between a given object and a unit solid cube by computing their harmonic mapping. We set the unit solid cube as a rectilinear parametric domain for trivariate B-splines and utilized the mapping to approximate the given object with B-splines in a coarse-to-fine manner. Specifically, our framework provides user-controllability of shape approximations, based on the control of the boundary condition of the harmonic parameterization and the level of B-spline fitting. Experimental results showed that our method is efficient enough to compute trivariate B-splines for several models, each of whose topology is identical to a solid sphere.
Detection method of visible and invisible nipples on digital breast tomosynthesis

Digital Breast Tomosynthesis(DBT) with 3D breast image can improve detection sensitivity of breast cancer more than 2D mammogram on dense breast. The nipple location information is needed to analyze DBT. The nipple location is invaluable information in registration and as a reference point for classifying mass or micro-calcification clusters. Since there are visible nipple and invisible nipple in 2D mammogram or DBT, the nipple detection of breast must be possible to detect visible and invisible nipple of breast. The detection method of visible nipple using shape information of nipple is simple and highly efficient. However, it is difficult to detect invisible nipple because it doesn’t have prominent shape. Mammary glands in breast connect nipple, anatomically. The nipple location is detected through analyzing location of mammary glands in breast. In this paper, therefore, we propose a method to detect the nipple on a breast, which has a visible or invisible nipple using changes of breast area and mammary glands, respectively. The result shows that our proposed method has average error of 2.54±1.47mm.

This document specifies the operation of mobile computers using IPv6. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about the mobile node's current location. IPv6 packets addressed to a mobile node's home address are transparently routed to its care-of address. The protocol enables IPv6 nodes to cache the binding of a mobile node's home address with its care-of address, and to then send packets destined for the mobile node directly to it at this care-of address. Status of This Memo This document is a submission by the Mobile IP Working Group of the Internet Engineering Task Force (IETF). Comments should be submitted to the Working Group mailing list at "mobile-ip@SmallWorks.COM". Distribution of this memo is unlimited. This document is an Internet-Draft.

The Role of Hypoxia in Re-educating Macrophages in the Tumour Environment

Monocytes and macrophages are myeloid cells which originate in the bone marrow and are essential in the primary defence against infection by bacteria, viruses and other pathogens. These cells circulate as monocytes in the bloodstream before undergoing extravasation and migration into adjacent tissues, where they differentiate into resident macrophages. Considerable monocyte extravasation occurs at the initial stages of inflammation, wound healing, tumour onset and various other diseases in response to chemotactic signals. In many instances these inflamed and/or diseased tissues have been shown to include areas of extremely low oxygen tension, termed hypoxia, by the measurement of oxygen concentrations using microelectrodes, use of hypoxic cell markers and/or expression of specific hypoxia-upregulated proteins. Such hypoxic areas are evident in the majority of malignant human cancers, including those of the breast, brain, cervix, head/neck, and soft tissue sarcomas (Raleigh et al., 2001; Vaupel et al., 1989), and are caused by an inability of the supporting vasculature to keep up with the oxygen demands of the rapidly increasing tumour mass (Shannon et al., 2003; Vaupel et al., 2005).
Prognostic impact of lymphadenectomy in uterine clear cell carcinoma

Objective The aim of this study was to estimate the survival impact of lymphadenectomy in patients diagnosed with uterine clear cell cancer (UCCC). Methods Patients with a diagnosis of UCCC were identified from Surveillance, Epidemiology, and End Results (SEER) program from 1988 to 2007. Only surgically treated patients were included. Statistical analysis using Student t-test, Kaplan-Meier survival methods, and Cox proportional hazard regression were performed. Results One thousand three hundred eighty-five patients met the inclusion criteria; 955 patients (68.9%) underwent lymphadenectomy. Older patients (≥65) were less likely to undergo lymphadenectomy compared with their younger cohorts (64.3% vs. 75.9%, p<0.001). The prevalence of nodal metastasis was 24.8%. Out of 724 women who had disease clinically confined to the uterus and underwent lymphadenectomy, 123 (17%) were found to have nodal metastasis. Lymphadenectomy was associated with improved survival. Patients who underwent lymphadenectomy were 39% (hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.52 to 0.72; p<0.001) less likely to die than patient who did not have the procedure. Moreover, more extensive lymphadenectomy correlated positively with survival. Compared to patients with 0 nodes removed, patients with more extensive lymphadenectomy (1 to 10 and >10 nodes removed) were 32% (HR, 0.68; 95% CI, 0.56 to 0.83; p<0.001) and 47% (HR, 0.53; 95% CI, 0.43 to 0.65; p<0.001) less likely to die, respectively. Conclusion The extent of lymphadenectomy is associated with an improved survival of patients diagnosed with UCCC.
Do confabulators really try to remember when they confabulate? A case report

Since Korsakoff's (1889/1955) first descriptions of confabulation at the end of the 19th century, all attempts to understand this neuropsychological disorder have focused on memory dysfunctions. Although the precise mechanisms underlying confabulation are still a matter of debate, the prevalent view is that confabulation is the output of a faulty recollective process. In the present paper we raise doubts about this undemonstrated assumption, arguing that confabulators are not necessarily attempting to recall when they confabulate. We describe a patient (M.L.) who floridly confabulated after a ruptured aneurism of the anterior communicating artery. The patient was administered a range of verbal tasks that required either memory recollection or other kinds of cognitive processes not involving memory. We conclude that the memory dysfunction exhibited by our patient represents one of many manifestations of a more general underlying disorder characterized by an inability to select the cognitive process that matches the task requirements in conjunction with a compulsion to provide verbal responses.
Stretchable Suction Cup with Electroadhesion

Suction cups are commonly used as adhering and grasping devices. This study proposes a methodology to expand the applicability of suction cups. A suction cup is developed with a soft pad which consists of stretchable electrodes and insulating layers that bond to the bottom of the main body of the suction cup. When the stretchable electrodes generate an electrostatic attraction between the electrodes and the object, the pad deforms, filling the gaps between the pad and the object. Due to the soft pad, the amount of incoming air is significantly reduced compared to a normal suction cup. Experiments reveal the effect of these features. Applying a high voltage to the stretchable electrodes increases the holding success ratio of the suction cup in the normal direction for smooth and rough surfaces due to the stretchable electrodes. Measuring the negative pressure inside the suction cup confirms that the electrostatic force maintains the adhesion force on both smooth and rough surfaces. Thus, the electrostatic force and stretchability of the soft pad greatly increase the adhesion force of the suction cup. Furthermore, the electrostatic force prevents a slip of the suction cup, which improves the performance of the suction cup.
