HERMES Precision Results on g1p, g1d and g1n and the First Measurement of the Tensor Structure Function b1d
Final HERMES results on the proton, deuteron and neutron structure function
g1 are presented in the kinematic range 0.0021<x<0.9 and 0.1<Q2<20 GeV2. These
results base on a refined analysis and are corrected for radiative and detector
smearing effects using an unfolding algorithm. Furthermore, preliminary results
on the first measurement of the tensor asymmetry Azz and the tensor structure
function b1d are presented.Comment: Proceedings for Spin 2004 conference (16th international spin physics

Behavioral and Experimental Economics Can Inform Public Policy: Some Thoughts
Experimental and behavioral economics are well established branches in the economic science. This essay presents and discusses some results and behavioral regularities from these fields which are of potential importance for public policy. After a brief introduction of what experimental and behavioral economics is, some behavioural regularities as presentation and framing effects, pro-social behavior, and reciprocity are introduced and it is reported how they interact with prominent trading institutions, taxation, and social and individual well-being. Throughout some implications for public policy are discussed.public economics, experimental economics, behavioral economics, public policy
Effective bounds on ampleness of cotangent bundles
We prove that a general complete intersection of dimension , codimension
and type in has ample cotangent bundle if
and the 's are all greater than a bound that is in
and quadratic in . This degree bound substantially improves the
currently best-known super-exponential bound in by Deng, although our
result does not address the case .Comment: Uses a result of Darondeau to improve the bound
Directed generosity and network formation: network dimension matters
We explore network effects on generosity for different network dimensions. To this end we elicit multiple network dimensions (friendship, social support, economic exchange, etc.) in a rural village in the Southern hemisphere and measure generosity with a sequence of dictator games conducted in the field. We find that networks of different dimensions differ substantially in density, clustering, and centrality. When relating generosity to networks we observe that social distance only matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with generosity per se but that they have strong explanatory power for network formation
Inhibitory antibodies designed for matrix metalloproteinase modulation
The family of matrix metalloproteinases (MMPs) consists of a set of biological targets that are involved in a multitude of severe pathogenic events such as different forms of cancers or arthritis. Modulation of the target class with small molecule drugs has not led to the anticipated success until present, as all clinical trials failed due to unacceptable side effects or a lack of therapeutic outcome. Monoclonal antibodies offer a tremendous therapeutic potential given their high target selectivity and good pharmacokinetic profiles. For the treatment of a variety of diseases there are already antibody therapies available and the number is increasing. Recently, several antibodies were developed for the selective inhibition of single MMPs that showed high potency and were therefore investigated in in vivo studies with promising results. In this review, we highlight the progress that has been achieved toward the design of inhibitory antibodies that successfully modulate MMP-9 and MMP-14
