ScALPEL: A Scalable Adaptive Lightweight Performance Evaluation Library for application performance monitoring

As supercomputers continue to grow in scale and capabilities, it is becoming increasingly difficult to isolate processor and system level causes of performance degradation. Over the last several years, a significant number of performance analysis and monitoring tools have been built/proposed. However, these tools suffer from several important shortcomings, particularly in distributed environments. In this paper we present ScALPEL, a Scalable Adaptive Lightweight Performance Evaluation Library for application performance monitoring at the functional level. Our approach provides several distinct advantages. First, ScALPEL is portable across a wide variety of architectures, and its ability to selectively monitor functions presents low run-time overhead, enabling its use for large-scale production applications. Second, it is run-time configurable, enabling both dynamic selection of functions to profile as well as events of interest on a per function basis. Third, our approach is transparent in that it requires no source code modifications. Finally, ScALPEL is implemented as a pluggable unit by reusing existing performance monitoring frameworks such as Perfmon and PAPI and extending them to support both sequential and MPI applications.Comment: 10 pages, 4 figures, 2 table

Pap smear in antepartum women: an opportunity to screen and create awareness

Background: Cervical and breast cancers are the leading malignancies in females in India. Cancer cervix is preventable and treatable if detected at premalignant stage. Pap smear is a recommended screening method for cancer cervix and its precursors. Pap smear screening in antenatal period presents an opportunity to screen for premalignant cervical lesions and genital infections. This study was undertaken to determine the prevalence of abnormal cervical smears and genital infections among antenatal women.Methods: It is a prospective study in which, 200 antenatal mothers at booking visit, were included in the study. Details on their demographic characteristics, obstetric profile, and past history of Pap test were collected. Liquid based cytology was used for the test. The cytological results were reported based on the Bethesda classification system 2001.Results: Among 200 antenatal women 57% were between 21-25 yrs of age and 18% were less than 20 years. 38% of women were less than 20 years of age at the time of beginning of sexual activity. 56% were primi gravida and others were multi gravida. 95.5 % of women were literate. 89% of women were unaware of Pap smear test. Among the 200 Pap smear reports, 23% were normal, 55.5% nonspecific inflammatory changes, 8.5% Candida infection and 13% bacterial vaginosis. None were reported with premalignant changes.Conclusions: In a population where people do not undergo Pap test due to varied reasons, antenatal Pap test not only provides an excellent opportunity to screen and create awareness for further screening, also helps detect genital infections

Management of Peri Implant deficiency with PRP and bone grafts – A Case Report

The objective of this paper is to report a case that has been successfully managed by incorporating Platelet Rich Plasma ( PRP) with a combination of autogenous bone graft and a commercial xenograft (BIO-OSS).                                                  Platelet rich plasma seems to enhance early bone healing (3 months) when used along with Auto grafts and Xeno graft mixture. A Substantial increase in the area of bone was observed post operatively. In our case, Clinically,  no major complications were noted after 3months when assessed using parameters like implant mobility, pain, infection, implant exposure. Therefore, the use of Platelet rich plasma along with auto graft and xeno graft mixture in peri implants deficient regions appears to be beneficial in  clinical situations. &nbsp

Lightweight Encrytion Scheme against Flow Analysis in Multi-Hop Wireless Network Based on Network Coding

Traffic analysis is a major issue faced in multi-hop wireless networks (MWN) in the case of privacy preservation. Network coding is essential in achieving greater capacity for any network and we extend this network coding for privacy preservation in multi-hop networks as it offers coding and mixing functions at intermediate nodes. Certain existing privacy preserving methods like onion routing can be employed here. Applying homomorphic encryption on Global Encoding Vectors(GEV’s), our method offers confidentiality and privacy preserving features. Only the sink has capability of decrypting the message content by inverting the GEV. Here, we focus on the privacy issue in order to prevent traffic analysis and flow tracing and achieve source anonymity in MWNs. Source anonymity refers to carrying the communication through the network maintaining the secrecy of the source node. Energy consumption when compared with the existing system was found to be reduced. Simulative evaluation by NS2 shows the efficiency of the system. Keywords: MWN, Privacy preservation, NS2, GEV

An Adaptive Scheme for Admission Control in ATM Networks

This paper presents a real time front-end admission control scheme for ATM networks. A call management scheme which uses the burstiness associated with traffic sources in a heterogeneous ATM environment to effect dynamic assignment of bandwidth is presented. In the proposed scheme, call acceptance is based on an on-line evaluation of the upper bound on cell loss probability which is derived from the estimated distribution of the number of calls arriving. Using this scheme, the negotiated quality of service will be assured when there is no estimation error. The control mechanism is effective when the number of calls is large, and tolerates loose bandwidth enforcement and loose policing control. The proposed approach is very effective in the connection oriented transport of ATM networks where the decision to admit new traffic is based on thea priori knowledge of the state of the route taken by the traffic

Effect Of Online Education On Elementary Education In India

The mishaps happening in online education can cost a lot to the students who are getting educated by it in many ways. Elementary students particularly suffer immensely in terms of health, safety due to the online mode of education. The education system for young kids is viewed as a sacred stage since it helps in imparting basic knowledge to a human being. Yet, there are many Initiatives to help the problem, but it is still not enough. The objective of this study is to find whether online education is fruitful for the elementary school, and to deduce how many hours is advisable for elementary class, also to find how much health is getting affected, likely also to see if gadgets is advised to provide to the elementary students, lastly to ascertain which mode of education is most preferable for elementary education. Unlike in the case of doctrinal research where the research is conducted on the basis of facts and data already collected in the library, archives and other databases, collecting or gathering information by a first-hand study into the universe, it helps the empirical research to be carried on. There are a total of 1005 samples collected with regard to this study. Hence, through these figures, we are able to understand that there is not much reception regarding online education for elementary students among the general public but truly they are at a confused level about which mode is truthfully the good one for elementary school students

Real Time Water Quality Monitoring and Flow Diverting System

Nowadays, almost every person on earth is facing trouble because of growing population, aging infrastructure and pollution. There are several types of pollution namely: Soil, Land, Water, Air etc. Water is a very precious resource for all living beings and its pollution is a grave concern for the society. One major reason for water pollution is industrial waste. The indiscriminate discharge of these wastewater streams into the environment pollutes the receiving bodies. The traditional method to challenge pH, turbidity and other parameters is to collect samples manually and then send them to laboratory for quality check. However, it has been unable to achieve water quality examining. The proposed system consists of model based on IoT platform and uses temperature, pH and turbidity sensors to check the water quality. Water quality is monitored and data from the sensors are sent to the web server at regular interval of time under RaspberryPi-3 using internet. The proposed system is free from any external or human interference and it can be used for water bodies like rivers and ponds

Flower orientation influences floral temperature, pollinator visits and plant fitness

Effective insect pollination requires appropriate responses to internal and external environmental cues in both the plant and the pollinator. Helianthus annuus, a highly outcrossing species, is marked for its uniform eastward orientation of mature pseudanthia, or capitula. Here we investigate how this orientation affects floral microclimate and the consequent effects on plant and pollinator interactions and reproductive fitness. We artificially manipulated sunflower capitulum orientation and temperature in both field and controlled conditions and assessed flower physiology, pollinator visits, seed traits and siring success. East-facing capitula were found to have earlier style elongation, pollen presentation and pollinator visits compared with capitula manipulated to face west. East-facing capitula also sired more offspring than west-facing capitula and under some conditions produced heavier and better-filled seeds. Local ambient temperature change on the capitulum was found to be a key factor regulating the timing of style elongation, pollen emergence and pollinator visits. These results indicate that eastward capitulum orientation helps to control daily rhythms in floral temperature, with direct consequences on the timing of style elongation and pollen emergence, pollinator visitation, and plant fitness.University of Virginia; Division of Integrative Organismal Systems; University of California Berkeley; US Department of Agriculture-National Institute of Food and Agriculture.http://www.newphytologist.comhj2022Plant Production and Soil Scienc
