New Form

Gravitational waves are a new form of energy that is too sensitive to measure. The study of gravitational waves paves a unique way to approach the new era of universal science. It is quite interesting to note that experimental proof of early theory of Einstein is successfully proven after many years. The manuscript depicts the concepts of gravitational waves, propagation of gravitational waves, its effect on objects on earth and various factors that affect the measurements along with their method of approach to detect gravitational waves. Detecting gravitational waves is a tedious process and it requires a very highly sensitive experimental setup to carry out the detection as well as on considering the current trend of technology it is observed that detection faceses massive limitations. Detection of gravitational waves  opens up a new way for understanding supermassive binary systems such as neutron stars and black holes and also for studying  on Early universe history.

AbstractTwo upcoming large scale surveys, the ESA Gaia and LSST projects, will bring a new era in astronomy. The number of binary systems that will be observed and detected by these projects is enormous, estimations range from millions for Gaia to several tens of millions for LSST. We review some tools that should be developed and also what can be gained from these missions on the subject of binaries and exoplanets from the astrometry, photometry, radial velocity and their alert systems.

The gravitational waves from compact binary systems are viewed as a standard siren to probe the evolution of the universe. This paper summarizes the potential and ability to use the gravitational waves to constrain the cosmological parameters and the dark sector interaction in the Gaussian process methodology. After briefly introducing the method to reconstruct the dark sector interaction by the Gaussian process, the concept of standard sirens and the analysis of reconstructing the dark sector interaction with LISA are outlined. Furthermore, we estimate the constraint ability of the gravitational waves on cosmological parameters with ET. The numerical methods we use are Gaussian process and the Markov-Chain Monte-Carlo. Finally, we also forecast the improvements of the abilities to constrain the cosmological parameters with ET and LISA combined with the Planck.

The integration of optical circuits with microfluidic lab-on-chip (LoC) devices has resulted in a new era of potential in terms of both sample manipulation and detection at the micro-scale. On-chip optical components increase both control and analytical capabilities while reducing reliance on expensive laboratory photonic equipment that has limited microfluidic development. Notably, in-situ LoC devices for bio-chemical applications such as diagnostics and environmental monitoring could provide great value as low-cost, portable and highly sensitive systems. Multiple challenges remain however due to the complexity involved with combining photonics with micro-fabricated systems. Here, we aim to highlight the progress that optical on-chip systems have made in recent years regarding the main LoC applications: (1) sample manipulation and (2) detection. At the same time, we aim to address the constraints that limit industrial scaling of this technology. Through evaluating various fabrication methods, material choices and novel approaches of optic and fluidic integration, we aim to illustrate how optic-enabled LoC approaches are providing new possibilities for both sample analysis and manipulation.

Market Capitalism

The rise of technocapitalism involves the commodification of knowledge in faster and more diverse ways than at any previous time in human history. This article provides insights from a macro-analytical perspective on the phenomena that mark the emergence of technocapitalism as a new form of market capitalism, and their influence on the commodification of knowledge for invention and innovation. The phenomena in question involve the rapid accumulation of inventions and of knowledge-sensitive infrastructure. The rapid reproduction of creativity and a faster diffusion of knowledge, both of which have been supported by a massification of technical education, are also important for the emergence of the new era. Their contribution to the commodification of technological knowledge is most obvious in the pervasive corporatization of invention and innovation, and even more so in the emergence of continuous invention and innovation as a standard component of corporate strategy.

AbstractThe article explores how Augustus and the priesthood of theXVviri sacris faciundisorganized and performed the rituals for celebrating a new era (ludi saeculares) under the rule of the gods Apollo and Diana. In the Republic, it had been a woman’s personal decision whether or not to take part in women’s festivals. However, theXVviricommanded that 110 married women (matronae) perform rituals (supplications and sacrifices) on the Capitoline. This article argues for the novelty of such a custom, in that it was a new form of top-down appeal tomatronaeto honor the gods in public festivals. The article also argues for the centrality of rituals of thematronaein the festival. At theludi saeculares, the cooperation between men (theXVviri) andmatronaewas ritually staged and seen as indispensable for ensuring the continuity of Rome.
