    Validation of Matching

    Full text link
    We introduce a technique to compute probably approximately correct (PAC) bounds on precision and recall for matching algorithms. The bounds require some verified matches, but those matches may be used to develop the algorithms. The bounds can be applied to network reconciliation or entity resolution algorithms, which identify nodes in different networks or values in a data set that correspond to the same entity. For network reconciliation, the bounds do not require knowledge of the network generation process

    A novel dry etching process for silicon dioxide has been developed. This process, carried out at ambient temperature and pressure, uses anhydrous hydrogen fluoride, water vapor in a nitrogen carrier, and a unique processing sequence to achieve etch rates of about 200A/second, with 5 percent or better uniformity. The overall reaction is a complicated sequence of surface hydration and surface fluorlnation by adsorption, reaction, and product desorptlon. This paper presents two proposed reaction mechanisms and describes how experimental data from a laminar flow reactor were used to evaluate the mechanisms

    An ovarian abscess is defined as a primary infection of the ovary without the involvement of the fallopian tube. The possible factors for the cause of ovarian abscess are: disruption of the ovarian capsule, giving access to bacteria, haematogenous and lymphatic spread. A woman with a ruptured ovarian abscess presents with features of diffuse peritonitis. An unruptured abscess is more difficult to diagnose. Unruptured abscess can be dealt with either laparotomy or laparoscopy. Ruptured ovarian abscess requires an aggressive and primarily surgical approach.

    Background: Medical termination of pregnancy is defined as “willful termination of pregnancy before the age of viability of the foetus. The objective was to study the socio-demographic & obstetric profile and the reasons for procuring an abortion & choice of health care provider.Methods: A Cross-sectional study was done in urban slum in Jamnagar municipal corporation area by using 30 clusters sampling technique. Every women in the reproductive age group (15-49 years) was included in the study till the sample size of 15 was completed in each cluster and thus total 450 women were interviewed. 48 women out of the total of 450 ever married women in the reproductive age group who had ever undergone induced abortion were studied in detailResults: In the present study out of 450 eligible women, 48 (10.67%) had undergone an induced abortion and once only. 72.91% (35/48) of the women belonged to the age group 25-34 years and 89.59% (43/48) of the women were Hindus. Almost half of the total women (45.83%) had primary education, higher proportion of women were housewife 77.09% (37/48). According to Modified Prasad’s classification, 54.17 % of women belonged to lower social class (IV and V). One third (33.33%) of the women who underwent MTP had 1 living child. Majority 79.16% of the women preferred government hospital and in 45.83% cases both husband and wife acted as decision maker for MTP. Most common reason given for terminating the pregnancy was “birth spacing”. (52.09%) Other reasons given were, “family completed” (22.91%), “medical” (14.58%) & social (4.17%). Majority of the women (70.83%) accepted post abortion contraception.Conclusion: There is need to counsel women of reproductive age group that MTP is not a way to control unwanted birth and it is not free from risk. They should be motivated for various methods of contraception.

    Rotating Scalar Field and Formation of Bose Stars

    We study numerical evolutions of an initial cloud of self-gravitating bosonic dark matter with finite angular momentum and self-interaction in kinetic regime. It is demonstrated that such a system can undergo gravitational condensation and form a Bose star. The results show that the gravitational condensation time is strongly influenced by the presence of finite angular momentum or the strength of self-interaction. We find that in the cases related with attractive or no self-interaction, there is no significant transfer of angular momentum from the initial cloud to the formed star. However, for the case repulsive interaction our results indicate that such a angular-momentum transfer is possible. These results are consistent with the earlier analytical work where the stability of the rotating boson star was considered [Dmitriev et al. 2021].Comment: New results have been incorporate

    Background: India contributes to 25% of the over 6.9 million under-five deaths occurring worldwide every year with nearly half of them in neonatal period .This study is related indirectly with the causes of U5MR (e.g. Neonatal sepsis, prematurity-LBW) through focusing on service utilization related to perinatal events & incorrect practices of essential Newborn care (e.g. initiation of breast feeding and exclusive breastfeeding). Objectives: (1) Assess utilization of child health services related to perinatal events (2) Assess incorrect practices related to perinatal events (3) Assess effect of demographic variables on service utilization and association of these variables with practices.Methods: A cross-sectional study of 400 children (12 to 59 months) was done using multistage sampling technique in Jamnagar district. 120 children were selected from urban and 280 from rural areas as urban: rural ratio is 3:7 in India.Results: 93.55% children having umbilical infection. Birth weights were taken in majority of children (95.75%), 15.83% of those weighed were having low birth weight (LBW). Application on umbilical cord after birth was seen in 10.25% & prelacteal feed in about 1/3rd children. Breastfeeding immediately or within 4 hours after birth was seen in 3/4th, exclusive breastfeeding in 2/3rd children.Conclusions: Children having umbilical infection were treated indicating better utilization of curative services. Taking of birth weights in majority of children indicating good functioning of healthcare professionals but some of those weighed were having low birth weight (LBW) indicating underutilization of preventive-antenatal services indirectly affecting child health. Incorrect practices like application on umbilical cord after birth and prelacteal feed were seen in children. Recommended practices like breastfeeding immediately or within 4 hours after birth, exclusive breastfeeding were seen in children. Colostrum giving was more prevalent and low birth weight was less prevalent in rural areas compared to urban areas which indicated better health care utilization in rural areas.

    BACKGROUND: The WHO defines LBW as Birth weight less than 2500 grams regardless of gestational age. Being born with a low birth weight also incurs enormous economic costs, including higher medical expenditures and social service expenses, and decreased productivity in adulthood. OBJECTIVE: To study distribution of newborns\u27 according to pregnancy related factors and its association with newborns\u27 birth weight. METHODS: An institutional based cross-sectional study. New-borns delivered at study institute were considered as study participants. Estimated final sample size was 500. Guardians (mothers) were face-to-face interviewed and also recorded data were collected from the case file and Mother and Child Protection Card. RESULTS: Prevalence of LBW newborns was higher in mothers with late ANC registration,visits, chronic medical conditions, infection during pregnancy, PIH, anemia, consuming tobacco, exposure to second hand smoke, LSCS/Assisted delivery, in female newborns\u27, current pregnancy birth order number more than 2, in pre term newborns\u27 and mothers with bad obstetric history. CONCLUSION: Create awareness and adoption of suitable family planning methods. Need to do early (within 12 weeks) ANC registration with minimum four ANC visits for better pregnancy outcome. Effective tracking and suitable intervention provided to improve current pregnancy outcome. Health care professional should pay special attention to high-risk pregnancy. Develop social culture in such a way that females are neither addicted nor exposed to any tobacco containing products in their life

    Background: Immunization is one of most cost effective public health intervention. Aims: (1) To assess immunization status among children of 12-23 months age group (2) To find out left out/dropout rate (3) To check association of socio demographic factors with immunization status. Material & Methods: A cross sectional study of sample 240 children aged between 12 to 23 months (using 30 cluster sampling technique) from Jamnagar municipal corporation area. Immunization of child was assessed through immunization card, presence of BCG scar & interview. Results: Out of 240 children, Coverage of BCG-99.58%, OPV0-94.58%, DPT1-98.33%, DPT2-96.67%, DPT3-95.42%, OPV1-96.67%, OPV2-95.83%, OPV3-4.58%. Coverage of HepB1, HepB2, and HepB3 were 73.33%, 70.42%, 68.75% respectively. Coverage of measles was 87.75%. Fully immunized children were 65%. Vaccine dropout of BCG-Measles was highest 11.34%, followed by DPT1-measles 10.58%. For BCG-DPT3 4.17%, DPT1-DPT3 2.96% & for HEP1-HEP3 6.25%. Fully immunized status was higher among male child as compare to female child which was statistically significant. Fully immunized children were more in Hindu religion compared to others which was statistically significant. No association found between educations of mother & immunization status of child. Socioeconomic class had no association with immunization status. Conclusion: Vaccination coverage shows gradual improvement in last decade (Fully immunized 65%) but at the same time reflects incomplete utilization (dropout rate is around 11%). Coverage was higher among male children as compared to female children which indicate the existence of gender difference in utilization of immunization services in our study areas. Utilization of immunization services was higher in Hindu community as compared to other community
