- Plant proteomics has made tremendous contributions in understanding the complex processes of plant biology. Here, its current status in India and Nepal is discussed. Gel-based proteomics is predominantly utilized on crops and non-crops to analyze majorly abiotic (49 %) and biotic (18 %) stress, development (11 %) and post-translational modifications (7 %). Rice is the most explored system (36 %) with major focus on abiotic mainly dehydration (36 %) stress. In spite of expensive proteomics setup and scarcity of trained workforce, output in form of publications is encouraging. To boost plant proteomics in India and Nepal, researchers have discussed ground level issues among themselves and with the International Plant Proteomics Organization (INPPO) to act in priority on concerns like food security. Active collaboration may help in translating this knowledge to fruitful applications.

- We revisit the idea that human subjects could control an on-screen presentation using pointing and drawing gestures made using a laser pointer on a presentation screen. One of the major hurdles of this kind of systems is to unambiguously distinguish between voluntary and involuntary gestures. We have investigated in this work specific spatio-temporal signature of gesture movements that could be used to distinguish between voluntary and involuntary gestures. Three simple gestures that could be made using a laser pointer; uni-directional drawing gesture, bi-directional drawing gesture and pointing gesture, had been used for the study. Subjects were asked to perform these tasks, with a laser pointer, on a screen. Our study showed that though the subjects tended to perform the tasks at their preferred tempo and the velocity profile of all subjects exhibited a task specific characteristic feature. Similar study with pointing gestures also revealed that the position of the laser pointer exhibited anisotropic Gaussian distribution, whose standard deviations decreased with the increase in dwell time.

Quantum trapping and rotational self-alignment in triangular Casimir microcavities

Tidskriftsartikel (refereegranskat)abstract
- Casimir torque, a rotational motion driven by zero-point energy minimization, is a problem that attracts notable research interest. Recently, it has been realized using liquid crystal phases and natural anisotropic substrates. However, for natural materials, substantial torque occurs only at van der Waals distances of ~10 nm. Here, we use Casimir self-assembly with triangular gold nanostructures for rotational self-alignment at truly Casimir distances (100 to 200 nm separation). The interplay of repulsive electrostatic and attractive Casimir potentials forms a stable quantum trap, giving rise to a tunable Fabry-Pérot microcavity. This cavity self-aligns both laterally and rotationally to maximize area overlap between templated and floating flakes. The rotational self-alignment is sensitive to the equilibrium distance between the two triangles and their area, offering possibilities for active control via electrostatic screening manipulation. Our self-assembled Casimir microcavities present a versatile and tunable platform for nanophotonic, polaritonic, and optomechanical applications.
