Three recently published Institute of Medicine reports, Hospital-Based Emergency Care: At the Breaking Point, Emergency Medical Services: At the Crossroads, and Emergency Care for Children: Growing Pains, examined the current state of emergency care in the United States. They concluded that the emergency medicine system as a whole is overburdened, underfunded, and highly fragmented. These reports did not specifically discuss the effect the aging population has on emergency care now and in the future and did not discuss special needs of older patients. This report focuses on the emergency care of older patients, with the intent to provide information that will help shape discussions on this issue.

The electronic structure and properties of linearly fused polycyclic hexasilabenzenoids (LF-PCHSBs) (an all silicon – analogue of polyaromatic hydrocarbons) is studied using Density Functional Theoretical (DFT) calculations at B3LYP/6-31G(d,p) level. The structure of LF-PCHSBs display chair like puckering with the formation of ordered pair of ripples. On increasing the number of rings, the oligomers exhibits $13° bending. The analysis of orbitals, reorganizational energy (RE) and electronic distribution properties demonstrated an aberrant behaviour with increasing length of PCHSB units. Lower the value of RE and uniform electronic distribution along with induced bending of the molecular system, more efficiently these oligomers exhibit the optoelectronics candidacy. The RE also helps to authorize the suitability of material for optoelectronic applications and thus assists in designing innovative molecules.
