We study the stretched membrane of a black hole as consisting of a perfect fluid. We find that the pressure of this fluid is negative and the specific heat is negative too. A surprising result is that if we are to assume the fluid be composed of some quanta, then the dispersion relation of the fundamental quantum is E = m/k, with m at the scale of the Planck mass. There are two possible interpr...

We show an inverted-U relation between targetiveness (probability of being targeted) and firm size. However, this pattern describes stock offers and is more pronounced during hot markets characterized by higher stock valuations. For cash offers we find a negative and monotonic relation. These contrasting patterns suggest that small firms (in the bottom NYSE size quartile) are less vulnerable to...

The aim of this paper is to identify and analyses the influence of shareholder ownership identity on payout ratio for a panel of Iran firms from 2002 and 2008. We find that there is a significant positive correlation between institutional ownership and payout ratio. The relation between payout ratio and individual ownership is negative. The most finding of the study indicates that Iranian compa...

Materials and methods In 312 Belgian children (5-12y) of the ChiBS study, the two-year longitudinal stress-lifestyle-adiposity relation was examined. Stress data (sum score of negative events, problem behaviour and negative emotions), lifestyle (food consumption, psychological eating behaviour, physical activity by accelerometry, screen time, sleep duration) and adiposity (BMI, fat% by BodPod, ...

This study examined the longitudinal relation between causal attributions and marital satisfaction and tested rival hypotheses that might account for any longitudinal association found between these variables. Data on attributions for negative partner behaviors, marital satisfaction, depression, and self-esteem were provided by 130 couples at 2 points separated by 12 months. To the extent that ...

This study examines the impacts of debt financing on the firms’ investment decisions by employing the method of the multiple linear regression on the data from 2006-2008 of 60 Chinese real estate listed companies. We obtain three major findings. First, there is a negative relation between debt financing and investment behavior in both firms with low-growth opportunities and high-growth opportun...

In isolated rat hearts perfused with HEPES and red blood cell-enriched buffers, we examined changes in left ventricular pressure induced by increases in heart rate or infusion of adenosine to investigate whether the negative force-frequency relation and the positive inotropic effect of adenosine are related to an inadequate oxygen supply provided by crystalloid perfusates. Hearts perfused with ...

Template dependencies (TD’s) are a class of data dependencies that include multivalued and join dependencies and embedded versions of these. A collection of techniques, examples and results about TD’s are presented. The principal results are: 1) Finite implication (implication over relations with a finite number of tuples) is distinct from unrestricted implication for TD’s. 2) There are, for TD...
