The effects of changing NMDA receptor subunit composition on synaptic plasticity in the hippocampus were analyzed by creating transgenic mice overexpressing NR2D, a predominantly embryonic NMDA receptor subunit. NMDA-evoked currents in the transgenic mice had smaller amplitudes and slower kinetics. The transgenics also displayed age-dependent deficits in synaptic plasticity in area CA1 of the hipp

The strawberry tortrix (Acleris comariana Lienig and Zeller) (Lepidoptera: Tortricidae), is a major pest of strawberry in Denmark and southern Sweden. Chemical and electrophysiological analyses revealed a single compound, (E)-11,13-tetradecadienal (E11,13-14:Ald), in gland extracts of females eliciting a strong antennal response in conspecific males. Also (Z)-11,13-tetradecadienal (Z11,13-14:Ald)

We theorize that three distinct structures of democratic constraint explain why more democratic dyads do not engage in military conflict with each other. We build on earlier theories that focused on electoral and horizontal accountability. We add a new dimension—the social accountability provided by an active civil society. Using several new measures from the Varieties of Democracy (V-Dem) data se

The success of the identification of the planar dilatation operator of N = 4 SYM with an integrable spin chain Hamiltonian has raised the question if this also is valid for a deformed theory. Several deformations of SYM have recently been under investigation in this context. In this work we consider the general Leigh-Strassler deformation. For the generic case the S-matrix techniques cannot be use

OBJECTIVE: The serotonin system has long been of interest in biological models of human personality. The purpose of this positron emission tomography (PET) study was to search for relationships between serotonin 5-HT(1A) receptor density and personality traits. METHOD: Fifteen normal male subjects, ages 20-45 years, were examined with PET and the radioligand [(11)C]WAY100635. Personality traits we

In this paper I argue that Small pro is not needed as a representative for null subjects in languages like Italian, Spanish, Standard Arabian etc. Instead I propose the Person Phrase hypothesis, which claims that agreement originates as the head of the subject argument. this argument is analyzed as PersP, seen as an expanded DP, [PersP Agr DP]. Agr is a bound morpheme, and thus cannot survive with

Popular Abstract in Swedish Avhandlingen innehåller fyra artiklar som berör olika aspekter av offentlig omfördelning i välfärdsstaten. Avhandlingen syftar till att ge kunskap om konsekvenser av, motiv för och mätande av och denna omfördelning. Den första artikeln ställer frågan: Hög hög skatteomfördelning från arbetande till icke arbetande kan motiveras av grundantagandet att naturresurser är gemThis thesis is an attempt to generate knowledge about the justification, measurement and consequences of public redistribution. The first paper poses the following question: How much redistribution from working to non-working can be justified by arguing that external resources are owned jointly by all, or that ownership should ideally be divided equally? This question is analyzed using bargaining

The presence of various mechanisms of non-genetic inheritance is one of the main problems for current evolutionary theory according to several critics. Sufficient empirical and conceptual reasons exist to take this claim seriously, but there is little consensus on the implications of multiple inheritance systems for evolutionary processes. Here we use the Price Equation as a starting point for a d

The main purpose of this article is to discuss the kinds of mental representations that are required for language to evolve. Firstly, I distinguish between cued and detached representations. A cued representation stands for something that is present in the current external situation of the representing organism, while a detached representation may stand for objects or events that are neither prese
