Maintenance of a Minimum Spanning Forest in a Dynamic Planar Graph

We give efficient algorithms for maintaining a minimum spanning forest of a planar graph subject to on-line modifications. The modifications supported include changes in the edge weights, and insertion and deletion of edges and vertices. To implement the algorithms, we develop a data structure called an edge-or&reck dynumic tree, which is a variant of the dynamic tree data structure of Sleator and Tarjan. Using this data structure, our algorithms run in O(logn) time per operation and O(n) space. The algorithms can be used to maintain the connected components of a dynamic planar graph in O(logn) time per operation. *Computer Science Laboratory, Xerox PARC, 3333 Coyote Hill Rd., Palo Alto, CA 94304.

A comparison of 1D and 2D LSTM architectures for the recognition of handwritten Arabic

In this paper, we present an Arabic handwriting recognition method based on recurrent neural network. We use the Long Short Term Memory (LSTM) architecture, that have proven successful in different printed and handwritten OCR tasks. Applications of LSTM for handwriting recognition employ the two-dimensional architecture to deal with the variations in both vertical and horizontal axis. However, we show that using a simple pre-processing step that normalizes the position and baseline of letters, we can make use of 1D LSTM, which is faster in learning and convergence, and yet achieve superior performance. In a series of experiments on IFN/ENIT database for Arabic handwriting recognition, we demonstrate that our proposed pipeline can outperform 2D LSTM networks. Furthermore, we provide comparisons with 1D LSTM networks trained with manually crafted features to show that the automatically learned features in a globally trained 1D LSTM network with our normalization step can even outperform such systems.

Hema e-Chart registry of invasive fungal infections in haematological patients: improved outcome in recent years in mould infections.

The electronic surveillance system Hema e-Chart allowed us to prospectively collect data and to perform an analysis of invasive fungal infections (IFI) diagnosed in febrile patients as well as the procedures allowing their diagnosis and outcome according to the treatment given. Every patient admitted to 26 Italian Haematology Units with a new diagnosis of haematological malignancy and who was a candidate for chemotherapy was consecutively registered between March 2007 and March 2009. In all, 147 haematological patients with mycoses were identified. Yeasts were found in 23 infections; moulds were diagnosed in 17 proven, 35 probable and 72 possible mycoses. Galactomannan (GM) antigen was the most important test to diagnose probable mould infection; it was positive (cut-off >0.5) in 27 (77%) probable and in nine (53%) proven mould infections. Among patients with probable/proven mould infection who received no prophylaxis or non-mould-active prophylaxis with fluconazole, more patients (n = 26, 78.8%) had GM antigen positivity compared with patients (n = 10, 52.6%) given prophylaxis with mould-active drugs (p <0.05). First-line antifungal therapy was effective in 11/23 (48%) yeast infections and in 37/52 (71.2%) proven/probable mould infections. Twenty patients (14%) died within 12 weeks. The fungal attributable mortality was 30.4% and 17.3% in yeast and proven/probable mould infections, respectively. Among risk factors only age was independently associated (p 0.013) with mortality; sex, underlying haematological malignancy, previous prophylaxis and presence of neutropenia at diagnosis were not significant. A diagnosis of mould infection seemed to have a trend for a better outcome than the diagnosis of yeast infection (p 0.064).
The role of hypertension and diabetes mellitus in the severity of gait and balance disturbances in iNPH

Background Idiopathic normal pressure hydrocephalus (iNPH) is a disorder characterized by gait and balance disturbances, urinary incontinence and cognitive impairment. Of these three, gait and balance disorders are often the first to manifest and also the group that improve the most after shunt surgery. Vascular risk factors (particularly hypertension and diabetes mellitus) has been shown to increase the risk of developing iNPH. There is however further need to investigate if these risk factors have any impact on the severity of symptoms and improvement after shunt surgery. The aim of this study is to examine the connection between hypertension, diabetes mellitus (DM) and the severity of gait and balance disturbances in patients diagnosed with iNPH preand postoperativley. The aim was also to determine if patients with risk factors present show less improvement in gait and balance after surgery compared to controls.
Enhancement of Tilted Beam in Elevation Plane for Planar End-Fire Antennas Using Artificial Dielectric Medium

This communication describes a simple and effective beamtilting technique for planar end-fire antennas using an artificial dielectric layer. The proposed approach is based on the phase differential resulting from a high refractive-index medium that is achieved using double G-shaped resonators (DGRs) in a 5 × 4 array. The array is oriented normal to the direction of the main beam emanating from the antenna. To demonstrate the principle, the technique is applied to a bow-tie antenna, which is designed at the WiMAX frequency band (3.4-3.6 GHz). The antenna performance was verified practically, and the measured results confirm that the direction of antenna's maximum beam can be refracted by 35° in the H-plane, which is larger than conventional techniques. In addition, a maximum gain enhancement of 5 dB is achieved when the beam is tilted. Reflection-coefficient of the proposed structure is maintained better than -10 dB across its operational band.

OPTIMIZATION OF EDM PARAMETERS USING TAGUCHI METHOD AND GREY RELATIONAL ANALYSIS FOR MILD STEEL IS 2026

Optimization is one of the techniques used in manufacturing sectors to arrive for the best manufacturing conditions, which is an essential need for industries towards manufacturing of quality products at lower cost. This paper aims to investigate the optimal set of process parameters such as current, pulse ON and OFF time in Electrical Discharge Machining (EDM) process to identify the variations in three performance characteristics such as rate of material removal, wear rate on tool, and surface roughness value on the work material for machining Mild Steel IS 2026 using copper electrode. Based on the experiments conducted on L9 orthogonal array, analysis has been carried out using Grey Relational Analysis, a Taguchi method. Response tables and graphs were used to find the optimal levels of parameters in EDM process. The confirmation experiments were carried out to validate the optimal results. Thus, the machining parameters for EDM were optimized for achieving the combined objectives of higher rate of material removal, lower wear rate on tool, and lower surface roughness value on the work material considered in this work. The obtained results show that the Taguchi Grey relational Analysis is being effective technique to optimize the machining parameters for EDM process.
Can Platelet-rich Plasma Be Used for Skin Rejuvenation? Evaluation of Effects of Platelet-rich Plasma on Human Dermal Fibroblast

BACKGROUND
Autologous platelet-rich plasma has attracted attention in various medical fields recently, including orthopedic, plastic, and dental surgeries and dermatology for its wound healing ability. Further, it has been used clinically in mesotherapy for skin rejuvenation.


OBJECTIVE
In this study, the effects of activated platelet-rich plasma (aPRP) and activated platelet-poor plasma (aPPP) have been investigated on the remodelling of the extracellular matrix, a process that requires activation of dermal fibroblasts, which is essential for rejuvenation of aged skin.


METHODS
Platelet-rich plasma (PRP) and platelet-poor plasma (PPP) were prepared using a double-spin method and then activated with thrombin and calcium chloride. The proliferative effects of aPRP and aPPP were measured by [(3)H]thymidine incorporation assay, and their effects on matrix protein synthesis were assessed by quantifying levels of procollagen type I carboxy-terminal peptide (PIP) by enzyme-linked immunosorbent assay (ELISA). The production of collagen and matrix metalloproteinases (MMP) was studied by Western blotting and reverse transcriptase-polymerase chain reaction.


RESULTS
Platelet numbers in PRP increased to 9.4-fold over baseline values. aPRP and aPPP both stimulated cell proliferation, with peak proliferation occurring in cells grown in 5% aPRP. Levels of PIP were highest in cells grown in the presence of 5% aPRP. Additionally, aPRP and aPPP increased the expression of type I collagen, MMP-1 protein, and mRNA in human dermal fibroblasts.


CONCLUSION
aPRP and aPPP promote tissue remodelling in aged skin and may be used as adjuvant treatment to lasers for skin rejuvenation in cosmetic dermatology.
Dynamic video summarization using two-level redundancy detection

The mushroom growth of video information, consequently, necessitates the progress of content-based video analysis techniques. Video summarization, aiming to provide a short video summary of the original video document, has drawn much attention these years. In this paper, we propose an algorithm for video summarization with a two-level redundancy detection procedure. By video segmentation and cast indexing, the algorithm first constructs story boards to let users know main scenes and cast (when this is a video with cast) in the video. Then it removes redundant video content using hierarchical agglomerative clustering in the key frame level. The impact factors of scenes and key frames are defined, and parts of key frames are selected to generate the initial video summary. Finally, a repetitive frame segment detection procedure is designed to remove redundant information in the initial video summary. Results of experimental applications on TV series, movies and cartoons are given to illustrate the proposed algorithm.
Node.js: Using JavaScript to Build High-Performance Network Programs

One of the more interesting developments recently gaining popularity in the server-side JavaScript space is Node.js. It's a framework for developing high-performance, concurrent programs that don't rely on the mainstream multithreading approach but use asynchronous I/O with an event-driven programming model.
Anatomy of unmanned aerial vehicle hijacking with signal spoofing

An important aspect about unmanned aerial vehicle (UAV, drone) hijacking to emphasize is being highly targeted cyber attack in terms of cyber warfare terminology that covers exploitation, offense, defence and asymmetrical war power as a whole. An attempt of hijacking is a combination of cyber and electronic operations/efforts rather than a single click takeover as it requires several tools and different techniques from cyber and electronic warfare domains simultaneously in a series of actions to achieve its objective particularly when the target is a military vehicle. Multi-stage nature of modern cyber attacks based on the coordination of individual offensive actions encompasses a fully executed UAV capturing assault. GPS spoofing is in the center of these scenarios and an obvious threat against civilian signals but also must be seriously handled in military domain too. Anatomical analysis of UAV hijacking attack delivers insights about vulnerabilities, methods to exploit, mechanisms to detect, how to deter the attack and evaluates the impacts.
Reliability and validity of the Advanced Basal Cell Carcinoma Index (aBCCdex).

BACKGROUND
Patient-reported outcome (PRO) questionnaires were recently developed specifically for use with patients with advanced basal cell carcinoma (aBCC) and basal cell carcinoma naevus syndrome (BCCNS).


OBJECTIVES
To evaluate the measurement properties of PRO questionnaires for use in patients with aBCC or BCCNS.


METHODS
In total 129 patients from 10 clinical sites in the U.S.A. and the BCCNS Support Network completed the two newly developed questionnaires multiple times over 3 months. Patients also completed the Skindex-16 and the 12-Item Short-Form Health Survey as collateral measures. Psychometric properties of the questionnaires were evaluated, including internal consistency and test-retest reliability, construct and known-groups validity, and responsiveness.


RESULTS
Based on the results of exploratory factor analysis and clinical input, the two newly developed questionnaires were combined into a single questionnaire, called the aBCCdex, which is relevant for patients with both aBCC and BCCNS. The internal consistency reliability was acceptable, and all aBCCdex scale scores correlated significantly with conceptually similar scales. When divided into groups that differed based on scores from collateral measures, aBCCdex scale scores differentiated between groups (known-groups validity) and were responsive to change.


CONCLUSIONS
The aBCCdex is a brief and comprehensive questionnaire appropriate for use with patients with aBCC and BCCNS. Its reliability and validity have been confirmed. Further research is necessary to estimate the minimally important difference in a larger patient population.
Exploiting hierarchical CP-nets to increase the reliability of Web services workflow

Individual Web services can be composed together to form value-added composite Web services represented as business process workflow. However, the value of such composite Web services is directly influenced by the reliability of the composite services. Composing Web services is not an easy task and is error-prone, so there is a growing interest for the verification techniques which enable designers to find and repair design errors even before actual running of the service, or allow designers to detect erroneous properties such as deadlocks or livelocks and formally verify whether the service process design does have certain desired properties (such as consistency with the conversation protocols of partner service). In this paper, we present to analyze and verify Web services composition by using some kind of colored Petri nets (CP-nets) called hierarchical CP-nets, which combine the strengths of Petri nets with the expressive power of high-level programming and have sound mathematical semantics. Services composition proposals can be transformed by transformation rules into CP-nets, which can be simulated to analyze the performance and verified to investigate behavioral properties by exploiting existing CP-nets specialized tools
Lapatinib monotherapy in patients with relapsed, advanced, or metastatic breast cancer: efficacy, safety, and biomarker results from Japanese patients phase II studies

Background:HER2-positive metastatic breast cancer (MBC) relapsing after trastuzumab-based therapy may require continued HER2 receptor inhibition to control the disease and preserve the patients' quality-of-life. Efficacy and safety of lapatinib monotherapy was evaluated in Japanese breast cancer patients after trastuzumab-based therapies.Methods:In studies, EGF100642 and EGF104911 evaluated the efficacy and safety of oral lapatinib given 1500 mg once daily in patients with advanced or MBC. All patients progressed on anthracyclines and taxanes; HER2-positive patients had also progressed on trastuzumab.Results:For HER2-positive tumours (n=100), objective response rate was 19.0% (95% confidence interval (CI): 11.8–28.1) and clinical benefit rate (CBR) was 25.0% (95% CI: 16.9–34.7). One out of 22 HER2-negative tumour was documented as complete response (n=22). The median time-to-progression (TTP) in the HER2-positive and HER2-negative groups was 13.0 and 8.0 weeks (P=0.007); median overall survival was 58.3 and 40.0 weeks, respectively. The most frequent adverse event was diarrhoea. TTP and CBR were significantly associated with HER2 expression. Patients with tumours harbouring an H1047R PIK3CA mutation or low expression of PTEN derived clinical benefit from lapatinib.Conclusion:Lapatinib monotherapy had shown anti-tumour activity in Japanese patients with HER2-positive MBC that relapsed after trastuzumab-based therapy, including those with brain metastases. Patients benefiting from lapatinib may have biomarker profiles differing from that reported for trastuzumab.
Set similarity search beyond MinHash

We consider the problem of approximate set similarity search under Braun-Blanquet similarity <i>B</i>(<i>x</i>, <i>y</i>) = |<i>x</i> â© <i>y</i>| / max(|<i>x</i>|, |<i>y</i>|). The (<i>b</i><sub>1</sub>, <i>b</i><sub>2</sub>)-approximate Braun-Blanquet similarity search problem is to preprocess a collection of sets <i>P</i> such that, given a query set <i>q</i>, if there exists <i>x</i> â <i>P</i> with <i>B</i>(<i>q</i>, <i>x</i>) â¥ <i>b</i><sub>1</sub>, then we can efficiently return <i>x</i>â² â <i>P</i> with <i>B</i>(<i>q</i>, <i>x</i>â²) > <i>b</i><sub>2</sub>. 
We present a simple data structure that solves this problem with space usage <i>O</i>(<i>n</i><sup>1+Ï</sup>log<i>n</i> + â<sub><i>x</i> â <i>P</i></sub>|<i>x</i>|) and query time <i>O</i>(|<i>q</i>|<i>n</i><sup>Ï</sup> log<i>n</i>) where <i>n</i> = |<i>P</i>| and Ï = log(1/<i>b</i><sub>1</sub>)/log(1/<i>b</i><sub>2</sub>). Making use of existing lower bounds for locality-sensitive hashing by OâDonnell et al. (TOCT 2014) we show that this value of Ï is tight across the parameter space, i.e., for every choice of constants 0 < <i>b</i><sub>2</sub> < <i>b</i><sub>1</sub> < 1. 
In the case where all sets have the same size our solution strictly improves upon the value of Ï that can be obtained through the use of state-of-the-art data-independent techniques in the Indyk-Motwani locality-sensitive hashing framework (STOC 1998) such as Broderâs MinHash (CCS 1997) for Jaccard similarity and Andoni et al.âs cross-polytope LSH (NIPS 2015) for cosine similarity. Surprisingly, even though our solution is data-independent, for a large part of the parameter space we outperform the currently best data-<em>dependent</em> method by Andoni and Razenshteyn (STOC 2015).
Intradiscal electrothermal therapy (IDET) provides effective symptom relief in patients with discogenic low back pain.

STUDY DESIGN
Single-arm, prospective clinical trial.


OBJECTIVE
To evaluate back pain severity, physical function, and quality of life outcomes in highly selected patients with lumbar discogenic pain treated with intradiscal electrothermal therapy (IDET).


SUMMARY OF BACKGROUND DATA
Degeneration and disruption of the intervertebral disc can be the source of severe low back pain and the associated physical dysfunction. IDET is a minimally invasive treatment option in the continuum of care between conservative nonoperative management and spinal surgery.


METHODS
Using magnetic resonance imaging, pressure-controlled discography, and postdiscogram computed tomography findings, 56 patients with lumbar discogenic pain were identified, underwent IDET treatment and followed for 20.5+/-4.4 months, on average. Outcomes included assessments of back pain severity by visual analog scale, sitting, standing, and walking tolerances, and health-related quality of life using the SF-36.


RESULTS
Mean pain severity scores (visual analog scale) improved from 6.1+/-1.8 pretreatment to 2.4+/-2.6 at final follow-up (P=0.0001). Mean tolerance times (minutes) improved from 40.9+/-40.6 to 84.5+/-54.4, 46.8+/-42.9 to 84.4+/-54.2, and 39.2+/-39.6 to 77.9+/-50.8 between baseline and final follow-up for sitting, standing, and walking, respectively (P=0.0001 for all comparisons). Seven of 8 quality of life domains showed significant (P=0.0001 for all comparisons) improvement over baseline. Forty-two patients (75%) were classified as a treatment success by virtue of a >or=2-point improvement in pain severity or a >or=10-point improvement in either the physical functioning or bodily pain domain of the SF-36.


CONCLUSIONS
The findings of this study suggest that durable clinical improvements can be realized after IDET in highly selected patients with mild disc degeneration, confirmatory imaging evidence of annular disruption, and concordant pain provocation by low pressure discography.
Resource Allocation in Cloud Computing Using the Uncertainty Principle of Game Theory

Virtualization of resources on the cloud offers a scalable means of consuming services beyond the capabilities of small systems. In a cloud that offers infrastructure such as processor, memory, hard disk, etc., a coalition of virtual machines formed by grouping two or more may be needed. Economical management of cloud resources needs allocation strategies with minimum wastage, while configuring services ahead of actual requests. We propose a resource allocation mechanism for machines on the cloud, based on the principles of coalition formation and the uncertainty principle of game theory. We compare the results of applying this mechanism with existing resource allocation methods that have been deployed on the cloud. We also show that this method of resource allocation by coalition-formation of the machines on the cloud leads not only to better resource utilization but also higher request satisfaction.
