Second Order Corrections to the Magnetic Moment of Electron at Finite Temperature
Magnetic moment of electron at finite temperature is directly related to the
modified electron mass in the background heat bath. Magnetic moment of electron
gets modified when it couples with the magnetic field at finite temperature
through its temperature dependent physical mass. We show that the magnetic
moment of electron becomes a complicated function of temperature and even
change its temperature dependent behavior around the energies for primordial
nucleosynthesis. We calculate the self-mass induced thermal contributions to
the magnetic moment of electron, up to the two loop level, for temperatures
valid around the era of primordial nucleosynthesis. A comparison of thermal
behavior of the magnetic moment is also quantitatively studied in detail,
around the temperatures below and above nucleosynthesis temperature range
A review of the empirical studies of computer supported human-to-human communication
This paper presents a review of the empirical studies of human-to-human communication which have been carried out over the last three decades. Although this review is primarily concerned with the empirical studies of computer supported human-to-human communication, a number of studies dealing with group work in non-computer-based collaborative environments, which form the basis of many of the empirical studies of the recent years in the area of CSCW, are also discussed. The concept of person and task spaces is introduced and then subsequently used to categorise the large volume of studies reported in this review. This paper also gives a comparative analysis of the findings of these studies, and draws a number of general conclusions to guide the design and evaluation of future CSCW systems
On linear equations arising in Combinatorics (Part I)
The main point of this paper is to present a class of equations over integers
that one can check if they have a solution by checking a set of inequalities.
The prototype of such equations is the equations appearing in the well-known
Gale-Ryser theorem
