 Effect of in-medium parameters of rho meson in its photoproduction reactions on nuclei / Das, Swapan There exist model calculations showing the modification of the hadronic parameters of $\rho$ meson in the nuclear environment. From these parameters, we extract the $\rho$ meson nucleus optical potential and show the medium effect due to this potential on the $\rho$ meson mass distribution spectra in the photonuclear reaction.

 Measurements of Newton's gravitational constant and the length of day / Anderson, John D ; Schubert, Gerald ; Trimble, Virginia ; Feldman, Michael R About a dozen measurements of Newton's gravitational constant, G, since 1962 have yielded values that differ by far more than their reported random plus systematic errors. We find that these values for G are oscillatory in nature, with a period of P = 5.899 +/- 0.062 yr, an amplitude of (1.619 +/- 0.103) x 10^{-14} m^3 kg^{-1} s^{-2}, and mean-value crossings in 1994 and 1997.

 The Gravitational Wave Background From Coalescing Compact Binaries: A New Method / Evangelista, E F D ; de Araujo, J C N Gravitational waves are perturbations in the spacetime that propagate at the speed of light. The study of such phenomenon is interesting because many cosmological processes and astrophysical objects, such as binary systems, are potential sources of gravitational radiation and can have their emissions detected in the near future by the next generation of interferometric detectors.

 Monte Carlo simulation to investigate the formation of molecular hydrogen and its deuterated forms / Sahu, DIpen ; Das, Ankan ; Majumdar, Liton ; Chakrabarti, Sandip K $H_2$ is the most abundant interstellar species. Its deuterated forms ($HD$ and $D_2$) are also significantly abundant. [...] arXiv:1504.06453.- 2015 - 20 p. - Published in : New Astron. 38 (2015) 0 External link: Preprint

 Search for Interstellar Adenine / Chakrabarti, Sandip K ; Majumdar, Liton ; Das, Ankan ; Chakrabarti, Sonali It is long debated if pre-biotic molecules are indeed present in the interstellar medium. Despite substantial works pointing to their existence, pre-biotic molecules are yet to be discovered with a complete confidence. [...] arXiv:1504.06444.- 2015 - 13 p. - Published in : Astrophys.

 Luminous Red Galaxies: Selection and classification by combining optical and infrared photometry / Prakash, Abhishek ; Licquia, Timothy C ; Newman, Jeffrey A ; Rao, Sandhya M We describe a new method of combining optical and infrared photometry to select Luminous Red Galaxies (LRGs) at redshifts $z > 0.6$. We explore this technique using a combination of optical photometry from CFHTLS and HST, infrared photometry from the WISE satellite, and spectroscopic or photometric redshifts from the DEEP2 Galaxy Redshift Survey or COSMOS.

 Field Equations in the Complex Quaternion Spaces / Weng, Zi-Hua The paper aims to adopt the complex quaternion and octonion to formulate the field equations for electromagnetic and gravitational fields. Applying the octonionic representation enables one single definition to combine some physics contents of two fields, which were considered to be independent of each other in the past.

 Yarkovsky effect in Generalized Photogravitational 3-Bodies Problem / Ershkov, Sergey V Here is presented a generalization of photogravitational restricted 3-bodies problem to the case of influence of Yarkovsky effect, which is known as reason of additional infinitesimal acceleration of a small bodies in the space (due to anisotropic re-emission of absorbed energy from the sun, other stellar sources). Asteroid is supposed to move under the influence of gravitational forces from 2 massive bodies (which are rotating around their common centre of masses on Kepler trajectories), as well under the influence of pressure of light from both the primaries.

 Automated weighing by sequential inference in dynamic environments / Martin, A D ; Molteno, T C A We demonstrate sequential mass inference of a suspended bag of milk powder from simulated measurements of the vertical force component at the pivot while the bag is being filled. We compare the predictions of various sequential inference methods both with and without a physics model to capture the system dynamics.

 Nuclear polarization study: New frontiers for tests of QED in heavy highly charged ions / Volotka, Andrey V ; Plunien, Günter A systematic investigation of the nuclear-polarization effects in one- and few-electron heavy ions is presented. The nuclear-polarization corrections in the zeroth and first orders in $1/Z$ are evaluated to the binding energies, the hyperfine splitting, and the bound-electron g factor.
