Preventing falls is a primary nursing concern, especially among older adult patients. Employing a sitter is a common but costly intervention. This article is a comprehensive review of the literature on sitter use and its effect on fall rates in acute care. The search was conducted in CINAHL, MEDLINE, PsycINFO, and the Psychology and Behavioral Sciences Collection and included articles published...

We continue the study of thermodynamics of black holes in de Sitter spaces. In a previous paper (hep-th/0111093), we have shown that the entropy of cosmological horizon in the Schwarzschild-de Sitter solutions and topological de Sitter solutions can be expressed in a form of the Cardy-Verlinde formula, if one adopts the prescription to compute the gravitational mass from data at early or late t...

Flapping wing miniature aerial vehicles (FWMAVs) offer advantages over traditional fixed wing or quadrotor MAV platforms because they are more maneuverable than fixed wing aircraft and are more energy efficient than quadrotors, while being quieter than both. Currently, autonomy in FWMAVs has only been implemented in flapping vehicles without independent wing control, limiting their level of con...

We propose that for every event in de Sitter space, there is a CPT-conjugate event at its antipode. Such an “elliptic” identification provides a concrete realization of observer complementarity in de Sitter space: every observer has complete information. This proposal naturally leads to a holographic description in which the dual (conformal) field theory lives on a single sphere. Correlation fu...
