Alarm Coloring and Grouping algorithm for root cause analysis

Over the last few years, network management systems have increased exponentially in various dimensions such as size and complexity. In such systems, components are connected to each other for providing various services. However, a failure in a component may eventually affect other interlinked components. Therefore, the service interruption problem may occur in the network systems. One of the solutions to this problem is to generate an alarm, in order to detect the fault and its possible restoration. Moreover, the alarm is to be processed in real-time, to avoid unwanted service interruption. For this, many researchers have presented various algorithms to handle the alarms. Such methods are time-consuming which is a major drawback in fault management. To overcome this, here we have proposed a method comprising two novel algorithms, namely Alarm Coloring and Alarm Grouping. In Alarm Coloring algorithm, a color scheme is used in order to distinguish the alarms, and subsequently, those alarms are grouped on the basis of distinguished colors. The proposed method is extensively simulated and compared with the existing alarm grouping method (s).

To determine the efficacy of ultrasonography in the evaluation of bone fill at the regenerate site for mandibular distraction osteogenesis over clinical and radiographic assessment– An in vivo prospective study

Until date conventional radiographs and computed tomography are the preferred diagnostic modalities to monitor the distraction osteogenesis regenerate. But these techniques do not detect the ongoing osteogenic process; moreover they obligate the patient to serial radiation exposure. In addition, anatomic overlap and metal artifacts obscure the virtual findings. In contrast, ultrasound is a noninvasive, efficient and an inexpensive way to evaluate bone healing. This study was conducted to test the efficacy of ultrasound in evaluating bone healing at the mandibular distraction site. Twenty patients underwent mandibular distraction. The wounds were assessed with an orthopantomograph and an ultrasound at the end of latency, mid distraction, end of distraction and post distraction periods i.e. 6 weeks, 8 weeks and 4months. Estimates of bone formation, using a semiquantitative radiological, ultrasonographic and intraoperative surgical bone fill scores were made. The correlation between intraoperative and ultrasonographic bone fill scores was statistically significant at 0.602, a total of 26 of the 31 sites correlated. Corresponding correlation between intraoperative and radiographic bone fill scores was 0.332, and only 13 of the 31 sites correlated. The results indicate that ultrasound is potentially an accurate noninvasive technique that is most useful in assessing the mandibular distraction regenerate.

Ocular Flutter in Scrub Typhus

A 9-year-old boy presented with a subacute febrile illness with bursts of conjugate horizontal saccadic oscillations on visual fixation (Figure and Video; available at www.jpeds.com) and cerebellar ataxia. Examination revealed hepatosplenomegaly and scrotal eschar. Magnetic resonance imaging of the brain was normal and lumbar cerebrospinal fluid showed lymphocytic pleocytosis (70 cells, protein 105 mg/dL). IgM enzyme-linked immunosorbent assay for scrub typhus was positive. Intravenous doxycycline and dexamethasone for 5 days resulted in complete recovery. Ocular flutter is bursts of conjugate horizontal saccades without intersaccadic interval, occurring on visual fixation, irrespective of gaze direction and eye closure. Ocular movements are present in full direction, hence ocular flutter may lead to troublesome oscillopsia. Ocular flutter is usually present with ataxia and myolconus and rarely can be isolated phenomenon. Ocular flutter is considered as a milder version of opsoclonus; ocular flutter or saccadic intrusions are usually horizontal, whereas opsoclonus are multidirectional. Pathogenesis of ocular flutter is related to dysfunction of omnipause neurons in the paramedianpontine reticular formation or fastigial nucleus of cerebellum. Damage to the GABAergic omnipause neurons or malfunction of glycine receptors causing a decrease in the efficacy of omnipause neuron-mediated inhibition leads to ocular flutter. Hydrocephalus, midbrain glioma, demyelinating disorders, enterovirus encephalitis, Lyme disease, autoimmune encephalitis, heredodegenerative disorders, and head trauma are reported with ocular flutter. Ocular flutter in an index child is a rare clinical feature of scrub typhus cerebellitis. Immune-mediated pathogenesis (anti-GQ1b, antiGADAntibodies) complements the role of steroids in early recovery. ■

Study of the influence of Zr on the mechanical properties and functional response of Ti-Nb-Ta-Zr-O alloy for orthopedic applications

In Ti-Nb-Ta-Zr based beta-titaniumalloys intended for orthopedic applications, Zr does not affect the stability of low modulus beta-phase, unlike Nb and Ta. The present study attempts to investigate the influence of Zr on the overall mechanical and functional responses of a Ti-Nb-Ta-Zr-O alloy in contrast to a new Ti-Nb-Ta-O alloy. In each material, different crystallographic textures were produced by varying the processing route. While both alloys were found to show low elastic modulus values due to their beta-only microstructures, Ti-Nb-Ta-O alloy had lower elastic modulus because of its favorable crystallographic orientation caused by absence of Zr. The tensile strength values were remarkably high for both due to the presence of interstitial oxygen. The hardening effect of Zr was also evident from the higher strength of Ti-Nb-Ta-Zr-O as compared to Ti-Nb-Ta-O alloy. Although the corrosion resistance and in vitro biological behavior of the two alloys were satisfactory, the Ti-Nb-Ta-Zr-O alloy showed lower corrosion rate and improved osteoblast attachment than the Ti-Nb-Ta-Oalloy. Thus, whereas the two alloys show promising performance in terms of their mechanical and functional response, presence of Zr marginally improves the performance in the Ti-Nb-Ta-Zr-O for orthopedic applications.

CATARACTS: Challenge on automatic tool annotation for cataRACT surgery

Surgical tool detection is attracting increasing attention from the medical image analysis community. The goal generally is not to precisely locate tools in images, but rather to indicate which tools are being used by the surgeon at each instant. The main motivation for annotating tool usage is to design efficient solutions for surgical workflow analysis, with potential applications in report generation, surgical training and even real-time decision support. Most existing tool annotation algorithms focus on laparoscopic surgeries. However, with 19 million interventions per year, the most common surgical procedure in the world is cataract surgery. The CATARACTS challenge was organized in 2017 to evaluate tool annotation algorithms in the specific context of cataract surgery. It relies on more than nine hours of videos, from 50 cataract surgeries, in which the presence of 21 surgical tools was manually annotated by two experts. With 14 participating teams, this challenge can be considered a success. As might be expected, the submitted solutions are based on deep learning. This paper thoroughly evaluates these solutions: in particular, the quality of their annotations are compared to that of human interpretations. Next, lessons learnt from the differential analysis of these solutions are discussed. We expect that they will guide the design of efficient surgery monitoring tools in the near future.

Dosimetric and isocentric variations due to patient setup errors in CT-based treatment planning for breast cancer by electronic portal imaging

Inaccuracies in treatment setup during radiation therapy for breast cancers may increase risks to surrounding normal tissue toxicities, i.e. organs at risks (OARs), and compromise disease control. This study was planned to evaluate the dosimetric and isocentric variations and determine setup reproducibility and errors using an online electronic portal imaging (EPI) protocol.
