Sampling hurdles : “Borderline Illegitimate” to legitimate data.
No full textIn this paper the author discusses how sampling access and recruitment problems encountered in an in-depth interview study heightened her sensitivity to “borderline illegitimate” data. The term illegitimate data usually refers to the data collected during a covert study, whereas “legitimate” data are collected during an overt study. Hence, data collected during any nonconsented period(s) of an overt study lie on the borderline of illegitimacy and legitimacy, and constitute what the author calls borderline illegitimate data. Such data need legitimization before use. The borderline illegitimate data were collected during the pre- and postinterview stages of her study as they explained how medical and ethnic cultures and sensitivity to racism as a topic combined to create sample recruitment difficulties of the study. The author later legitimized them by sharing them with the participants, guaranteeing anonymity, and asking their permission to use them
Unpacking the impact of the TikTok ban on local content creators and the rise of Indianized social media apps.
No full textThis paper investigates the repercussions of the TikTok ban in 2020 and the subsequent migration of local content creators to alternative platforms, with a particular focus on the identity negotiation of the marginalized LGBTQIA+ community. The author positions this paper as an exploration of the displacement experienced by rural young queers in expressing their queerness following the ban. TikTok was a platform that transcended class barriers and provided an equal platform for socioeconomically diverse users. However, its ban led to the emergence of Indianized social media apps that have further segregated the classes. The author argues that this phenomenon requires academic attention because the rise of these Indian apps coincides with the overshadowing of right-wing populism. By exploring these complex dynamics, this paper contributes to the understanding of the impact of digital media on the social fabric of contemporary India.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/177335/1/15-Garg-Tiktok-Social Media and Society in India Proceedings-66-72-10.73027932.pdfSEL

Leggett-Garg inequalities for quantum fluctuating work
No full textThis is the author accepted manuscript. The final version is available from MDPI via the DOI in this recordThe Leggett-Garg inequalities serve to test whether or not quantum correlations in time can be explained
within a classical macrorealistic framework. We apply this test to thermodynamics and derive a set of LeggettGarg
inequalities for the statistics of fluctuating work done on a quantum system unitarily driven in time. It
is shown that these inequalities can be violated in a driven two-level system, thereby demonstrating that there
exists no general macrorealistic description of quantum work. These violations are shown to emerge within the
standard Two-Projective-Measurement scheme as well as for alternative definitions of fluctuating work that are
based on weak measurement. Our results elucidate the influences of temporal correlations on work extraction
in the quantum regime and highlight a key difference between quantum and classical thermodynamics.HM is supported by EPSRC through a Doctoral

Atomic "bomb testing": The Elitzur-Vaidman experiment violates the Leggett-Garg inequality
No full text\ua9 The Author(s) 2018. Elitzur and Vaidman have proposed a measurement scheme that, based on the quantum superposition principle, allows one to detect the presence of an object-in a dramatic scenario, a bomb-without interacting with it. It was pointed out by Ghirardi that this interaction-free measurement scheme can be put in direct relation with falsification tests of the macro-realistic worldview. Here we have implemented the "bomb test" with a single atom trapped in a spin-dependent optical lattice to show explicitly a violation of the Leggett-Garg inequality-a quantitative criterion fulfilled by macro-realistic physical theories. To perform interaction-free measurements, we have implemented a novel measurement method that correlates spin and position of the atom. This method, which quantum mechanically entangles spin and position, finds general application for spin measurements, thereby avoiding the shortcomings inherent in the widely used push-out technique. Allowing decoherence to dominate the evolution of our system causes a transition from quantum to classical behavior in fulfillment of the Leggett-Garg inequality
Applications of Nanoproteomics in Biological Systems
No full textThe high-throughput techniques used in nanoproteomics generally outperform in comparison to normal proteomics techniques. Approaches like disease biomarker detection in humans are one of the major achievements, which have led to the detection of different biomarkers for autoimmune, infectious, neurodegenerative and cardiovascular disease. The use of novel sensors and different nanoproteomic approaches also helps in identifying biomarkers for different types of cancer and other diseases. In plant biology, nanoproteomic assists in gene transfer, creation of deoxyribonucleic acid crystals and identification and quantification of total protein. It also has application in microbial proteomics research. Using nanoproteomics has also helped in studying allied scientific areas like proteobionics and secretomics. This review article covers the current application and future prospects of nanoproteomics approaches
Water Deficit at the Anthesis Stage Induces Early Leaf Senescence and Affects Dry Matter Accumulation and Remobilization Efficiency in Black Gram (P. mungo, L.)
No full textTo investigate the effects of two levels of irrigation regimes (full irrigation [FI], i.e., normal water supply; and limited irrigation [LI], i.e., limited water supply) on growth and grain yield of two varieties of Phaseolus mungo (PU 19 and Type 9), a greenhouse experiment with three replicates was conducted from February to May in 2005. Results showed that pots in which water-deficit stress was introduced at the anthesis stage induced early senescence in both varieties (PU 19 and Type 9). Leaf chlorophyll content declined more quickly as leaves approached maturity for LI plants than for FI plants. The experiment demonstrated that var. PU 19 was a superior variety under both normal and limited irrigation conditions, compared with Type 9. It maintained high relative water content (RWCL) and net assimilation rate (NARL) in leaves under LI. PU 19 had the highest amount of remobilized dry matter (ARDM), remobilization efficiency (REE), remobilization efficiency percentage (REP), seed weight and grain yield (GY) under LI. We therefore conclude that senescence and remobilization are apparently promoted by a limited water supply or drought stress, and they are coupled processes. Studying RWC, NAR and leaf senescence can be used as indirect selection criteria for grain yield. This would be a beneficial for understanding of the many physiological mechanisms that confer water-deficit tolerance, leading to the development of leguminous plant species better adapted to such environments
Low backache in adults as an initial presentation of acute lymphoblastic leukemia
No full textLow backache as an initial manifestation of acute lymphoblastic leukemia (ALL) in adults has been rarely reported. In this hematological disorder, although bone marrow is replaced by malignant cells, not many cases of low backache as an initial presentation of ALL are reported. We present a series of clinical cases with low backache, which on evaluation found to have ALL
