THE PASSAGE: Enquiry into the Ephemeral Absence of Social Construct During Transitions
No full text“In the universe, there are things that are known, and things that are unknown, and in between them, there are doors.” ― William Blake. This thesis support paper presents my artistic research on the ephemeral nature of absence in social constructs while relocating myself to new places. I am interrogating a fluid positionality that is continuously shifting, leading me to contextualise the research stance in the between and betwixt of Passage. I am examining the experience of passing from one place, condition, or stage to another and highlight the in-between space made visible through artwork produced with various methods and processes. Throughout, absence is indicated via aesthetics, materiality, and immateriality pointing to subtle boundaries between play and seriousness, the real and imaginary, the ephemeral and permanent. Themes of travel, constraint, absence, liminality, and human consciousness are explored through performative installations, architectural spaces, and different degrees of audience participation. The research generates a dialogue between performance, space, and time which involves bodily experience, live actions with mixed media installations, and time-based works. The choice of media and symbols revolve around various conceptual ideas inspired by academic and non-academic sources — contemporary art, spiritual texts, psychology, lucid visions while meditating — which become the artistic expression's metaphorical core. Anchoring in an auto-ethnographic methodology of resisting mastery, the research was conducted by allowing space for unknowns to reveal their contours through silent being and doing by not doing

The patients in all three groups continued topical NTM 5% every four hours until the ulcer healed. Primary outcome measure was time taken till complete clinical resolution of infection, and secondary outcome measure was best corrected visual acuity (BCVA) at six months.Results: All three groups had comparable baseline parameters. The mean duration of healing was significantly better (p=0.02) in the ISNTM group (34± 5.2 days) as compared to the ISVCZ group (36.1± 4.8 days) and the ISAMB group (39.2± 7.2 days). About 95%, 90% and 95% patients healed successfully in the ISVCZ, ISAMB and ISNTM groups, respectively. In terms of healing, deep vascularization was significantly greater in the ISAMB group (55%, p=0.02) when compared to the ISVCZ and ISNTM groups (31% and 26%, respectively). There were fewer repeat injections in the ISNTM group (7/20 vs 8/20 and 9/20 in the ISVCZ and ISNTM groups, respectively).Conclusion: Intrastromal injections are a safe and effective adjunct to conventional therapy in the management of recalcitrant fungal keratitis. ISNTM had a similar visual outcome with faster healing while ISAMB had a higher rate of deep vascularization after healing.Keywords: intrastromal injections, recalcitrant fungal keratiti

No full textThyroid Cytology in India: Contemporary Review and Meta-analysis
No full textFine-needle aspiration cytology (FNAC) is a screening test for triaging thyroid nodules, aiding in subsequent clinical management. However, the advantages have been overshadowed by the multiplicity of reporting systems and a wide range of nomenclature used. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was formulated in 2007, to give the world a uniform thyroid cytology reporting system, facilitating easy interpretation by the clinicians. Here, we review the status of thyroid FNAC in India in terms of various reporting systems used including a meta-analysis of the previously published data. An extensive literature search was performed using internet search engines. The reports with detailed classification system used in thyroid cytology were included. The meta-analysis of published data was compared with the implied risk of malignancy by TBSRTC. More than 50 studies were retrieved and evaluated. TBSRTC is currently the most widely used reporting system with different studies showing good efficacy and interobserver concordance. Ancillary techniques have, as of now, limited applicability and acceptability in thyroid cytology in India. Twenty-eight published articles met the criteria for inclusion in the meta-analysis. When compared with TBSRTC recommendations, the meta-analysis showed a higher risk of malignancy for categories I and III. Thyroid FNAC is practiced all over India. TBSRTC has found widespread acceptance, with most institutions using this system for routine thyroid cytology reporting. However, reasons for a high malignancy risk for categories I and III need to be looked into. Various possible contributing factors are discussed in the review

No full textCosmic variance of the Hellings and Downs correlation for ensembles of universes having nonzero angular power spectra
No full textGravitational waves (GWs) induce correlated perturbations to the arrival times of pulses from an array of galactic millisecond pulsars. The expected correlations, obtained by averaging over many pairs of pulsars having the same angular separation (pulsar averaging) and over an ensemble of model universes (ensemble averaging), are described by the Hellings and Downs curve. As shown by Allen [Phys. Rev. D 107, 043018 (2023)], the pulsar-averaged correlation will not agree exactly with the expected Hellings and Downs prediction if the gravitational-wave sources interfere with one another, differing instead by a “cosmic variance” contribution. The precise shape and size of the cosmic variance depends on the statistical properties of the ensemble of universes used to model the background. Here, we extend the calculations of the cosmic variance for the standard Gaussian ensemble to an ensemble of model universes which collectively has rotationally invariant correlations in the GW power on different angular scales (described by an angular power spectrum, for =0,1,….). We obtain an analytic form for the cosmic variance in terms of the ’s and show that for realistic values /0 ≲10−3, there is virtually no difference in the cosmic variance compared to that for the standard Gaussian ensemble (which has a zero angular power spectrum)
Angular power spectra of anisotropic stochastic gravitational wave background: developing statistical methods and analyzing data from ground-based detectors
No full textUnresolved sources of gravitational waves can create a stochastic gravitational wave background (SGWB) which may have intrinsic or extrinsic anisotropies. The angular power spectrum is a well-suited estimator for characterizing diffuse anisotropic distributions in the sky. Here we estimate the first model-independent all-sky all-frequency SGWB angular power spectra in the 20-1726 Hz frequency range from the third observing run (O3) of the Advanced LIGO and Advanced Virgo detectors. We develop a method to use the spectrum\u27s signal-to-noise ratio as the detection statistic and show that the shape of the distribution of the statistic obtained from the data agrees with the analytical model with a modified value of the parameter. Since we find the data to be consistent with noise, confidence Bayesian upper limits are set on the angular power spectra, ranging from . We also introduce a method to combine the narrow band angular power spectra to obtain estimators for broadband SGWB. These results can directly constrain theoretical models that predict the SGWB angular power spectra and for estimating or constraining the corresponding parameters. In addition, the results and the techniques introduced in this work can be useful for performing correlation-based searches, for instance, with electromagnetic observations.14 Pages, 5 figures, 1 tabl
