This article characterizes the infinitesimal generators of semigroups of linear transformations.

Article on electronic and transport properties of artificial gold chains.

This article presents new H- and K-band spectroscopy of 15 high-luminosity active galactic nuclei at redshifts 2.3-3.4 obtained with Gemini South.

This article discusses a study on the regression to the origin of a walker driven by dynamically generated fractional Brownian motion.

This article describes two studies of individuals with high levels of psychopathic traits. Study 1 explores what aspects of social reward are associated with psychopathic traits, and Study 2 administers these measures to a new group of participants along with two experimental tasks investigating monetary and social reward value.

This article investigates the formation of magnetobound positronium and protonium via classical trajectory simulations of binary point charge interactions in an external magnetic field. The results of computer simulations of the fully three-dimensional trajectories of classical and non-relativistic point charges with the same mass, equal charge magnitude, and opposite sign are reported. The simulations show the formation of magnetobound positronium and protonium. The results yield formation cross sections, which are compared to analytical expressions. Additionally, the results reveal that magnetobound states drift across magnetic field lines.

This article reports the first effort to assess the impact of land-use change on soil diversity for the entire nation of China.

This article examines elevation trends and their control by seasonality, dominant geochemical processes, and season dynamics in these supraglacial ponds at elevations ranging between 3989 and 4292 m above sea level in the debris-covered area of Lirung glacier in central Nepal Himalayas, from November 2010 to October 2011 on a bimonthly basis.

Article reviews current research of role/function diversities of host matrix metal–organic frameworks (MOFs), noting the importance of understanding enzyme structural alternation and enzyme−MOF interaction after immobilization.
