In Binary Threshold Public Good (BTPG) games, n players have binary choices: cooperation or non-cooperation. If at least k cooperate, a public good is produced. The case = the Stag Hunt game with two pure strategy equilibria E1 (all cooperate) and E0 (no player cooperates). four rather diverse examples of four-player three prominent concepts equilibrium selection favor E0. Experiments, however,...

Zenker’s diverticulum can be treated successfully using flexible endoscopy [1]. Several methods have been used to cut the septum of the diverticulum, such as LigaSure (Medtronic, Minneapolis, Minnesota, USA), needle-knife, and other submucosal dissection devices. Recently, isolated cases using the stag beetle (SB) knife dissector, SB jr 3.5mm, have been reported [2–4]. We present the case of a ...

background and objectives: stress among students of the health sciences can lead to reduced performance of future healthcare human resources. to address this threat there is a need to develop a robust understanding of the nature and intensity of stress in these professionals. to help approaching this goal, the present study assessed stress-induced life change in students of tehran university of...

all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...

objective: an increasing number of studies have reported on shifts in timing and length of the growing season, based on phonological, satellite and climatologically studies. changes in the timing and length of the growing season (gsl) may not only have far reaching consequences for plant and animal ecosystems, but persistent increases in gsl may lead to long-term increases in carbon storage and...
