We present a lower bound for the free energy of a quantum many-body system at finite temperature. This lower bound is expressed as a convex optimization problem with linear constraints, and is derived using strong subadditivity of von Neumann entropy and a relaxation of the consistency condition of local density operators. The dual to this minimization problem leads to a set of quantum belief p...

Notwithstanding ERISA’s fiduciary requirements, a significant portion of 401(k) plans establish investment menus that predictably lead investors to hold high-cost portfolios. Using data from more than 3,500 401(k) plans with more than $120 billion in assets, we provide evidence that fees and menu restrictions in an average plan lead to a cost of seventy-eight basis points in excess of index fun...

background: morpholine is a toxic substance used in industry and agriculture and can be absorbed into the body through ingestion, inhalation, and the skin. the present study aimed to assess the effect of morpholine and physiological serum ingestion on qualitative and quantitative characteristics of white blood cells and kidney tissue of white male mice. materials and methods: in the present stu...

a territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. the typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. this is caused by low number of game in the community. white colored deer is in the location of the czechrepublicbred in separation since 18th century...
