primary colorectal lymphoma (pcl) is a rare condition that accounts for a small percentage of all gastrointestinal (gi) malignancies. there are several reports in the literature regarding the most common features of pcl. however, primary lymphoma in the rectosigmoid junction has been rarely reported. our case was a 67-year-old male who presented with non-specific symptoms of bowel obstruction w...

We propose different syntax-based methods for automatically identifying verb-particle constructions in English. The methods are based on the Deterministic Finitestate Automaton (DFA), Hidden Markov Model(HMM), and Synchronous ContextFree Grammar (SCFG). Our experiments show that the methods could result in F-score 83.3% over our manually annotated test-set consisting of Wikipedia articles and B...

Recent theoretical models suggest that motor learning includes at least two processes: error minimization and memory decay. While learning a novel movement, a motor memory of the movement is gradually formed to minimize the movement error between the desired and actual movements in each training trial, but the memory is slightly forgotten in each trial. The learning effects of error minimizatio...

Let Q be the set of all primitive words over a finite alphabet having at least two letters. In this paper, we study the language D(1) of all non-overlapping (d-primitive) words, which is a proper subset of Q. We show that D(1) is a contextsensitive langauage but not a deterministic context-free language. Further it is shown that [D(1)]n is not regular for n ≥ 1. key words: primitive word, non-o...

The traditional view of cognitive-motor control posits an executive module that sends instructions to motor cortex before each movement. In contrast, newer work suggests that manual movements in task switching are determined through the competition of multiple simultaneously active motor representations. The streaming x,y coordinates of participants’ computer mouse movements were recorded as th...

Contrasting to advances in street/outdoor navigation, wall mounted maps and signs continue to be the primary reference indoor navigation in hospitals, malls, museums, etc. The proliferation of mobile devices and the growing demand for location aware systems that filter information based on currently device location have led to an increase in research and product development in this field. An at...

Background Understanding and addressing the needs of frail persons is an emerging health priority for Nova Scotia and internationally. Primary healthcare (PHC) providers regularly encounter frail persons in their daily clinical work. However, routine identification and measurement of frailty is not standard practice and, in general, there is a lack of awareness about how to identify and respond...

Let R be a commutative ring and M be an R-module. We say that M is fully primary, if every proper submodule of M is primary. In this paper, we state some characterizations of fully primary modules. We also give some characterizations of rings over which every module is fully primary, and of those rings over which there exists a faithful fully primary module. Furthermore, we will introduce some ...
