Testing Electroweak Baryogenesis with Future Colliders

Electroweak Baryogenesis (EWBG) is a compelling scenario for explaining the matter-antimatter asymmetry in the universe. Its connection to the electroweak phase transition makes it inherently testable. However, completely excluding this scenario can seem difficult in practice, due to the sheer number of proposed models. We investigate the possibility of postulating a "no-lose" theorem for testing EWBG in future e+e- or hadron colliders. As a first step we focus on a factorized picture of EWBG which separates the sources of a stronger phase transition from those that provide new sources of CP violation. We then construct a "nightmare scenario" that generates a strong first-order phase transition as required by EWBG, but is very difficult to test experimentally. We show that a 100 TeV hadron collider is both necessary and possibly sufficient for testing the parameter space of the nightmare scenario that is consistent with EWBG.Comment: 26 pages + references, 10 figures.

Oneness And Self‐Centeredness In The Moral Psychology Of Wang Yangming

Rather than “selfishness,” a more accurate and revealing interpretation of Wang's use of siyu is “self‐centeredness.” One of the main goals in Wang's model of moral cultivation was to attain a state devoid of self‐centered desires. Wang relied a great deal on the exercise and cultivation of an emotional identification and feeling of oneness with others. In this paper, I first provide a brief summary of the role of Wang's concept of siyu in his moral psychology. I then examine key passages in Wang's writings that reveal his nuanced understanding of siyu and, along the way, I draw on empirical research in psychology to help illuminate the significance of Wang's view of siyu to his overall model of moral cultivation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90155/1/j.1467-9795.2011.00508.x.pd

Folk moral relativism

It has often been suggested that people’s ordinary folk understanding of morality involves a rejection of moral relativism and a belief in objective moral truths. The results of six studies call this claim into question. Participants did offer apparently objectivist intuitions when confronted with questions about individuals from their own culture, but they offered increasingly relativist intuitions as they were confronted with questions about individuals from increasingly different cultures or ways of life. In light of these data, the authors hypothesize that people do not have a fixed commitment to moral objectivism but instead tend to adopt different views depending on the degree to which they consider radically different perspectives on moral questions.

Simulation model of seat with implemented pneumatic spring

This article deals with description of simulation model of a seat with pneumatic element inserted into its cushioning. Suggested solution comprises built-in pneumatic spring with feedback control which influences the hardness of cushioning. The seat with variable cushioning properties should contribute to the increase of passenger’s comfort. In order to investigate properties of this seat-mass system the mathematical model was created and solved numerically. This model describes dynamic behavior of the electro-pneumatic mechanical system and calculates the displacement and acceleration of mass, pressure inside pneumatic spring, flow rate in controlled solenoid pneumatic valves and needed coil current in case of kinematic excitation of the seat, as well as the change of setting of desired pressure in pneumatic spring

The effect of system improvement on regulation of pressure inside pneumatic spring element and on transmission of acceleration

Following a patented solution, a seat which is possible to change its stiffness was created. The seat contains an actively controlled pneumatic spring element (the PSE). For the requirement of working faster and more precisely, an improvement was applied. This article focuses on a comparison of the effect of the improved system and the original system on regulation of pressure inside a PSE. For comparison, two system characteristics were used, the response time and the transmission of acceleration. The original and improved system were thoroughly studied and compared experimentally. The behavior of both systems is analyzed and evaluated. The function of pressure regulation is investigated under static conditions (without excitation) and the transmission of acceleration is performed under dynamic conditions (with excitation). The results describe the behavior of the system in two modes of controller setup: constant pressure and constant stiffness both under static and dynamic conditions
