A major whey protein which appears in milk from the tammar wallaby (Macropus eugenii) only during the second half of lactation (late lactation protein-A, LLP-A) was purified to apparent homogeneity by ion-exchange chromatography and gel filtration. An Mr of 21,600 +/- 2000 was calculated from its amino acid composition. A computer-based comparison of the sequence of the first 69 amino acid resi...

In this work, we explore how learners can infer second-language noun meanings in the context of their native language. Motivated by an interest in building interactive tools for language learning, we collect data on three word-guessing tasks, analyze their difficulty, and explore the types of errors that novice learners make. We train a log-linear model for predicting our subjects’ guesses of w...

This paper incorporates the systematic risk of regime shifts into a general equilibrium model of the term structure of interest rates. The regime-switching risk introduces a new source of time-variation in bond term premiums. A closedform solution for the term structure of interest rates is obtained for an affine-type model under log-linear approximation. The model is estimated by Efficient Met...

This paper describes the SEMAFOR system’s performance in the SemEval 2010 task on linking events and their participants in discourse. Our entry is based upon SEMAFOR 1.0 (Das et al., 2010a), a frame-semantic probabilistic parser built from log-linear models. The extended system models null instantiations, including non-local argument reference. Performance is evaluated on the task data with and...

In this paper, reasoning methods for the interval-based modal temporal logic LLP which employs the modal operators sometimes, always, next, and chop are described. A constraint deduction approach is proposed and compared with a sequent calculus which has been developed as the basic machinery for the deductive planning system PHI which uses LLP as underlying formalism.

Several techniques have recently been proposed for training “self-normalized” discriminative models. These attempt to find parameter settings for which unnormalized model scores approximate the true label probability. However, the theoretical properties of such techniques (and of self-normalization generally) have not been investigated. This paper examines the conditions under which we can expe...

Long-term changes in synaptic plasticity require new protein synthesis. This preview discusses data from Kim et al. (this issues of Neuron) that demonstrate the requirement of a novel, nucleolar protein, LLP (LAPS18-like protein), for the formation of long-term facilitation in Aplysia. LLP binds to and transcriptionally activates C/EBP, thereby promoting the formation of long-term facilitation ...
