Arguments are given that the lightest supersymmetric particle should be a neutralino χ. Minimizing the fine tuning of the gauge hierarchy favours Ωχh 2 ∼ 0.1. There are important constraints on the parameter space os the MSSM from the stability of the electroweak vacuum. Co-annihilation with the next-to-lightest supersymmetric particle is potentially significant. Incorporating the latest accele...

This paper develops a framework for constructing an R&D output price index. Based on a model of the innovator, we show that the price of innovation is equal to the expected discounted stream of profits attributable to the adoption of the innovation. Using this relationship, we construct an R&D output price index using data on NAICS 5417, Scientific R&D services. We compute that R&D output price...

With the development of higher voltage power grid, the high and low voltage parallel loops are emerging, which lead to energy losses, even threaten the security and stability of power system. The multi-infeed HVDC configurations widely appearing in AC/DC interconnected power system make this situation even worse. Aimed at energy saving and system security, a decision optimization method for pow...

We measured geomagnetic secular variation in Lake Lisan sediments (paleo Dead Sea). More than 1500 oriented samples were collected from a 27.3-m section of alternating aragonite and detritus laminae in the Dead Sea basin ranging in age from 67 to 32 ka. The natural remanent magnetization (NRM) is carried by titanomagnetite in the detrital laminae whereas the aragonite is diamagnetic. The NRM is...

Kaplain-Meier estimates are widely used for plotting survival curves over time, for one or more strata. Graphical display of survival estimates based on a continuous covariate are more problematic. We propose a simple approach to plotting survival estimates at a specified point in time, based on the value of a continuous explanatory variable. This approach allows for the adjustment of survival ...

Patent trolls have changed the innovation and patent policy landscape. This thesis is an empirical event study that focuses on two landmark cases of patent troll litigation, RIM v. NTP and eBay v. Mercexchange, to determine whether pro-troll litigation outcomes significantly impact the market values of the firms in the high-tech industries they target. I find that the Supreme Court ruling in eB...

When Usenet News servers were first implemented, the design principle of storing each Usenet article in a separate file appeared to be sound. However, the number of Usenet News articles posted per day has grown phenomenally in the past decade and shows no sign of abating. To stay ahead of the growth curve, Usenet administrators have been forced to buy faster machines, more RAM, and many more di...

Dade [D1, Theorem 7.4] obtained an important result on the equivalence of categories, extending the classical stable Clifford theory. He used the theory of strongly graded rings. Recently, this work has been generalized to arbitrary graded rings, see E. Dade [D2], [D3], J.L. Gómez Pardo and C. Nǎstǎsescu [GN ], C. Nǎstǎsescu and F. Van Oystaeyen [NVO2]. In the classical case the stable Clifford...

Background: Implementation of the International Classification of NANDA-I in neonatology care in the Czech Republic. Aim: The aim of the study was to validate the diagnostic elements of nursing diagnoses 00104 Ineffective Breastfeeding and 00106 readiness for inhanced breastfeeding selected file by neonatal nurses-experts and determine which diagnostic elements consider as the main, and which t...
