Understanding the degeneracies in NOA data
The combined analysis of disappearance and appearance data
of NOA experiment leads to three nearly degenerate solutions. This
degeneracy can be understood in terms of deviations in appearance
signal, caused by unknown effects, with respect to the signal expected for a
reference set of oscillations parameters. We define the reference set to be
vacuum oscillations in the limit of maximal and no CP-violation.
We then calculate the deviations induced in the appearance signal event
rate by three unknown effects: (a) matter effects, due to normal or inverted
hierarchy (b) octant effects, due to being in higher or lower
octant and (c) CP-violation, whether or . We find that the deviation caused by each of these effects is the
same for NOA. The observed number of events in NOA is
equivalent to the increase caused by one of the effects. Therefore, the
observed number of appearance events of NOA is the net result of
the increase caused by two of the unknown effects and the decrease caused by
the third. Thus we get the three degenerate solutions. We also find that
further data by NOA can not distinguish between these degenerate solutions
but addition of one year of neutrino run of DUNE can make a distinction between
all three solutions. The distinction between the two NH solutions and the IH
solution becomes possible because of the larger matter effect in DUNE. The
distinction between the two NH solutions with different octants is a result of
the synergy between the anti-neutrino data of NOA and the neutrino data of
DUNE.Comment: Published version v2; with minor changes to v
Tensions between the appearance data of T2K and NOvA
The long baseline neutrino experiments, T2K and NOvA, have taken significant
amount of data in each of the four channels: (a) disappearance, (b)
disappearance (c) appearance and (d)
appearance. There is a mild tension between the disappearance and the
appearance data sets of T2K. A more serious tension exists between the
appearance data of T2K and the appearance data of NOvA.
This tension is significant enough that T2K rules out the best-fit point of
NOvA at confidence level whereas NOvA rules out T2K best-fit point at
confidence level. We explain the reason why these tensions arise. We
also do a combined fit of T2K and NOvA data and comment on the results of this
fit.Comment: matches the published versio

Book of Abstracts & Success Stories National Conference on Marine Debris COMAD 2018
Marine debris has become a global problem with considerable threats to the habitat and to the
functions of marine ecosystem. One of the first reports of large areas of plastics in the ocean
has been by National Oceanic and Atmospheric Administration (NOAA) in 1988 about the
Great Pacific Garbage patch or the Pacific trash vortex, where the density of litter is estimated
as four numbers per cubic meter. Globally, this shocking information led to initiation of new
research programs on marine litter and in India, the ICAR-CMFRI started an in house research
program on this theme in 2007.Understanding the significance of this ecological problem
which is purely a direct impact of anthropogenic activity, the Marine Biological Association of
India decided to organise a National Conference on Marine Debris (COMAD 2018 ) with an
aim to bring together researchers, planners, NGOs, entrepreneurs and local governing bodies
working on this theme. Thus, this conference was planned with three main componentsunderstand
the research outputs, get first- hand information on the various activities carried
out by the public to reduce or recycle non degradable waste generated at various levels and
also to have an exhibition of eco-friendly activities and products which would help to reduce
marine debris in the long run.
The response to all the three themes has been very encouraging. We have received about 50
research articles on themes ranging from micro-plastics to ghost nets and the same number
of success stories which are actually details of the diverse activities carried out in different
maritime states of the country to solve the issue of solid waste generated in the country. The
section on success stories includes attempts by eco-clubs, individuals, schools, colleges, local
governing bodies, district administrations, Institutions and NGOs.
Activities by some Panchayats like banning plastics in public functions and mechanisms to
collect sold waste from households are really commendable. Similarly, the efforts put in by
various groups to remove marine debris from the coastal waters is something which should be
appreciated. The message from these success stories is that, this problem of increasing marine
debris can be resolved. We have got success stories from almost all states and these leaders of
clean campaign will be presenting their work in the conference.
It is well known that visuals such as photographs and videos are powerful tools of communication.
In COMAD 2018, we have provided an opportunity for all across the nation to contribute to
this theme through photographs and videos. Am very happy that we have received more than
300 photographs and nearly 25 videos. The MBAI will place these on the web site. It is really
shocking to see the quantity of litter in the fishing ground and in the coastal ecosystem
An Overview on the applications of different polymers in capture of Carbon dioxide from atmosphere
Carbon dioxide discharges are increasing at a quick speed in the environment. CO2 is a significant ozone-depleting gas, and its exhausts induce overall temperature variations, which bring about ecological adjustment. As the world accelerates in its battle against environmental modification, climate can differ from one location to the next. Still, when we talk about climate modification, weтАЩre discussing a variant in the usual weather patterns of an area. This could be because of a change in the PlanetтАЩs average temperature or maybe a modification in the number of rainstorms and snow. Human beings are progressively affecting the environment as well as the Planet. This includes many greenhouse gases contrasted to those discovered naturally in the atmosphere. Environment change is specified as an adjustment in the average conditions of an area, such as temperature level and rains, over an extended period of time. When we see where climate adjustment influences, unfortunately, it is throughout the world. This presentation will most likely go over various case studies. This evaluation focuses on carbon capture issues with the very best probability of limiting CO2 exhausts to the atmosphere from big point sources. According to a brand-new study that combines the most up-to-date research studies from the United Nations, the buildup of unmatched quantities of greenhouse gases in the environment devotes the world to disastrous future warming. Tape levels of greenhouse gases in the environment dedicate the Earth to disastrous future warming
Comparative analysis of conventional cytology and liquid-based cytology in the detection of carcinoma cervix and its precursor lesions
Context: The conventional smears (CS) and Liquid based cytology (LBC) are important tools to detect carcinoma cervix and its precursor lesions. Aims: The present study was done to compare the cytomorphological features of cervical lesions using both techniques and compare with the histopathological diagnosis. Settings and Design: This was a prospective observational study over a period of 1.5 years at a tertiary care hospital. Methods and Material: A total of 969 women in the age group of 21тАУ65 years presenting with either routine screening or complaints of vaginal bleeding, discharge, or pelvic pain were enrolled for the study. Both the CS and LBC smears were analyzed and compared with the corresponding histopathology diagnosis. The data was analyzed using Statistical Package for the Social Sciences (SPSS) software and P values <0.05 were considered significant. Results: There were 8.57% unsatisfactory smears in CS as compared to 0.5% in LBC smears. Liquid-based cytology was superior to conventional preparations in terms of smear adequacy, lesser hemorrhagic and inflammatory background, and presence of more endocervical cells. Liquid-based cytology showed a better yield in detecting all the types of epithelial cell lesions with a concordance rate of 73.9% between the two techniques. On histopathology correlation of these lesions, LBC had a higher sensitivity (96.67%) and diagnostic accuracy (99.08%) as compared to CS (73.33% and 92.66%, respectively). Conclusions: Liquid-based cytology is superior to conventional cytology for the detection of epithelial cell lesions. Reduction in the unsatisfactory smears, a cleaner background, and better representation of the sample are more significantly appreciated on LBC in contrast to CS
Understanding the degeneracies in NOvA data
