Two-neutrino double beta decay （2vββ） half-lives to the first excited state are calculated in the framework of quasi random phase approximation. The quadrupole transition probabilities and the 2vββ decay amplitudes to the final ground states are reproduced by using adjustable parameters. The obtained half-lives are compared with the corresponding experimental data.

A thin target of ^197Au is bombarded with 29 MeV protons from the cyclotron at Department of Nuclear Research Centre for Agriculture and Medicine. Correlated energies of fission-fragment pairs are measured with silicon surface-barrier detectors and their time of flights is made using a spectrometry pair. The fission cross section, fragment mass distribution, and total kinetic energy distribution of the fission fragments are measured in our experiment. The results are also compared with the previous works and good agreements are found.

Unsteady mixed convective boundary layer flow and heat transfer over a stretching vertical surface in the presence of slip axe investigated. It is noted that fluid velocity decreases due to the increasing velocity slip parameter resulting in an increase in the temperature field. The rate of heat transfer decreases with the velocity slip parameter while it increases with unsteadiness parameter. The same feature is also noticed for thermal slip parameter.

Treatments to repair the human heart following regenerative diseases remain a challenge for medical science. Unlike lower vertebrate species the human heart lacks a regenerative pathway meaning that research has to be focused on cell transplantation. Porcines (sus scrofa) are excellent models for cardiovascular disease and pluripotent stem cells (PsCs) generated from porcines will provide important clinical insights for cardiac cell therapy. This could open a new avenue of research into degenerative conditions as porcine is a more effective human proxy to work with. However, bona fide PsCs are currently available onlyin rodents (mouse, rat) and primates (monkey, human). Attempts to derivepluripotent stem cells (PsCs) from porcine have been going on for more than two decades with slow progress. Despite the fact that the porcine stem cells are under increasing glare of publicity due to milestone achievements in this area of research. Advances in stem cell technology, especially the genetic engineering, innovative cell culturing and induced pluripotency to generate stem cells has dramatically revolutionized the basic and applied investigations and applications of porcine stem cells. This review attempts to summarize the major signaling pathways involved in maintenance of pluripotency and the state of the art conceptual and technical progress for generating bona fide porcine PsCs.

Technological advancements in smart grid energy systems (sGEss) are introducing sustainable frameworksto meet the demand for the fourth industrial energy revolution. These frameworks are planned to be usedin the forthcoming future to maintain the energy network operation with optimization, energy trading, gridautomation, and so on. Blockchain (BCn), developing after passing a diverse period of the research journey,comes to the mind of researchers and its integration in sGEs paves the way to reach the goal of energydemand. However, still of interest is ongoing in the improvement of BCn features which can be regarded asthe next-generation blockchain framework. This paper exhibits the technical framework of the next-generationBCn framework and explores its benefits and challenges in performing the emerging aspects of sGEs. Thisframework enables some advanced features for the sustainable operation of sGEs like smart metering, peer-topeer (P2P) energy trading, self-operation, and transparency. The technical explanation of this BCn technologyestablished on essential features and requisites is also presented in this paper from various points of viewwhich include smart mechanism, intelligent storage system, and interoperability. We also highlight the recentprogress and limitations of the current BCn framework in sGEs. Finally, some challenges towards integratingthe next-generation BCn technology in sGEs are reported. This work can provide extended support for thepractitioner and researcher in the context of BCn technology and sGEs.

This study presents a novel nanostructural electrode made of 20-nm-diameter nanoparticles, which orderly decorated with 2-μm TiO2 particles, deposited by a new gel process. The decorated electrode （DE） is better than the non-decorated electrode （NE） in both light scattering and light harvesting, as confirmed by diffuse reflectance spectroscopy. X-ray diffraction reveals that both electrodes have a mixture of anatase and rutile phases. The dye-sensitized solar cell based on the decorated electrode shows the highest power conversion efficiency of 7.80% as a result of less recombination demonstrated by electrochemical impedance spectroscopy. From internal power conversion efficiency measurement, the external quantum efficiency of DE cell at 530 nm is 89%, which is higher than that of NE cell （77%）.
