Research on biomass and carbon stocks is very meaningful for managing and minimizing negative effects of climate change and global warming on people's lives. The study collected and analyzed data from plots for Acacia hybrid forests at two different age levels: 2 years and 6 years old in Ham Yen, Tuyen Quang. The analytical results showed that density at age 6 was lower than age 2. The diameter and height frequency distributions were well simulated by Weibull distribution.

Accumulating evidence suggests alternative splicing (AS) is a co-transcriptional splicing process not only controlled by RNA-binding splicing factors, but also mediated by epigenetic regulators, such as chromatin structure, nucleosome density, and histone modification. Aberrant AS plays an important role in regulating various diseases, including cancers.

Accurately quantifying the risk of osteoporotic fracture is important for directing appropriate clinical interventions. While skeletal measures such as heel quantitative speed of sound (SOS) and dual-energy X-ray absorptiometry bone mineral density are able to predict the risk of osteoporotic fracture, the utility of such measurements is subject to the availability of equipment and human resources.

In ebook "Density functional theory in quantum chemistry" density functional theory (DFT) is introduced within the overall context of quantum chemistry. DFT has become the most frequently used theory in quantum chemistry calculations. However, thus far, there has been no book on the fundamentals of DFT that uses the terminology and methodology of quantum chemistry, which is familiar to many chemists, including experimentalists.

Ebook "Density functionals: Thermochemistry" aims to reflect the current state of density-functional thermochemistry. It presents highlights of ongoing research at the frontiers of DFT and discusses the outstanding problems of delocalization error and strong correlation. The first few chapters give overviews of density-functional approximations as they currently stand and push the boundaries of their applicability to increasingly complex systems, consisting of very large molecules.
