glutathione s-transferase (gst) activity pattern was determined in tolerant (cv. sumai#3) and susceptible (cv. falat) wheat heads inoculated with fusarium graminearum, the causal agent of head scab disease (fhb), during various developmental stages. gst specific activity exhibited a transient pattern in sumai#3 reaching a maximum level at the milk stage and declining thereafter. gst level in su...

Bill Haddican NYU 6/18/2001 0. Introduction This paper makes three claims about Basque grammar. First, it argues that Cinque’s (1999) hierarchy of functional heads largely holds for Basque. In a typical pattern, lower morphemes in the hierarchy appear in the reverse order, while higher morphemes appear in Cinque’s order. This is explained through roll-up—iterative XP movement through specifier ...

One of the important tasks of a syntactic theory is to provide an account of the different dependency relations that hold between elements in a phrase.1 In Dependency Grammar (following various traditional grammatical traditions (cf. Lyons 1968), there are two basic types: complement and adjunct (or modifier). The first defines an obligatory relation between a functor (or head) and its argument...

Spoken language user interface can dramatically speed up computer use. Unfortunately, if the speech user interface gets in the way too often, the user turns it off. Users are unforgiving: a technology that impairs productivity just once may never get a second chance. In order to give the user interface a fighting chance, why not give it a certain amount of emotional sensitivity? Users respond b...

The skeleton of the neck and shoulders has undergone alterations during evolution, but muscle connectivity has not. A recent study suggests this is a result of neural crest cells defining attachment points and thus muscle connectivity.

Figure heads are words without autonomous content, such as the copula and the infinitival to. They pose a challenge for the head-driven semantics of HPSG-94, since the latter requires the CONTENTjNUCLEUS value of a head-complement combination to be identical to the one of its head daughter. As a consequence, if the head is semantically vacuous, the combination is —erroneously— predicted to be v...

An analysis of Hox genes reveals that the body of the adorably weird tardigrades is essentially a truncated front end. This illustrates that loss and simplification are a hallmark of the evolution of animal body plans.
