Hace 5 días · Epigenetics. Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi- ( ἐπι- "over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA ...
Hace 5 días · This work presents a thorough analysis of soliton wave phenomena in the (3+1)-dimensional Fractional Calogero-Bogoyavlenskii-Schiff equation (FCBSE) with Caputo’s derivatives through the use of a novel analytical technique known as the modified Extended Direct Algebraic Method (mEDAM). By converting nonlinear Fractional Partial Differential equations (FPDE) into integer-order Nonlinear ...
Hace 22 horas · Observational phenomena. There has been historical controversy over whether observed features on the Moon's surface change over time. Today, many of these claims are thought to be illusory, resulting from observation under different lighting conditions, poor astronomical seeing, or inadequate drawings.

Minimum Credits: 3 Maximum Credits: 3 Bio transport phenomena explores the similarities between the fundamental principles of momentum, heat, and mass transfer, develops analogies between the fundamentals that apply at microscopic and macroscopic scales, and uses the fundamentals in conjunction with ...
Hace 5 días · Sound wave is a longitudinal wave. That is, it has both compression and rarefactions. The pulsing sound in beats is due to the rise and fall in intensities. The rise in maximum intensity is called the waxing of sound and the minimum intensity of sound is called waning of sound. These two phenomena occur when two of the sound waves interfere ...
Hace 1 día · High-resolution observations with GRAVITY-VLTI instrument have provided abundant information about the flares in Sgr A*, the supermassive black hole in our Galactic center, including the time-dependent location of the centroid (a "hot spot"), the light curve, and polarization. Yuan et al. (2009) proposed a "coronal mass ejection" model to explain the flares and their association with the ...
