Curtus: An NLP Tool to Map Job Skills to Academic Courses
Many businesses are burdened with the need to train students for the job instead of finding them prepared for it. Few business leaders feel that colleges prepare students for future jobs from day one. It can be a challenge for colleges to determine if their curricula meet the industry needs. Mapping industry needs to academic courses can be advantageous to both parties as it will allow colleges to be aligned with the industry needs and accordingly satisfy those needs and will allow the industry to hire better prepared graduates. In an attempt to address this, a system prototype that uses a collection of job descriptions from various sites and syllabi of college courses as the input knowledge was developed. The primary goal of the system is to help students to find courses that would be most beneficial in providing them with the skills that match a given job description. The secondary goal is to help faculty to quickly find out information about current skills and tools covered in the existing courses, which accordingly can help them to make decisions about their future courses to satisfy the industry needs. The system was developed using the Natural Language Toolkit (NLTK) and the Python programming language. Two sets of keywords were used to test the system; the first one is the most common keywords and the second one includes the most and least common keywords. Results from testing the system demonstrate that using the former set of keywords allowed for better results with precision equal to 55% and recall equal to 39.61%

The Face of Interface: Studying Interface to the Scholarly Corpus and Edition
How can we study the interface of scholarly knowledge across print and digital epochs? To ask about interface across epochs is to take a concept that makes sense in the digital world and anachronistically bring it to bear on print in a way that could confuse both. Nonetheless we need to develop ways of thinking about the relationship between design, knowledge and audience across media, and to do that we find ourselves remediating concepts like interface. This paper takes the category of interface and adapts it to studying the design of the corpus and edition
Interfacing the Collection
The digital age has led to the advent of electronic collections with millions or even billions of items. This paper examines the types of interfaces that are emerging for large-scale collections, specifically addressing what a large collection looks like online and how it can be managed by users. In examining these questions, we propose some features that we feel are universally desirable in interfaces to collections. Overall, there appear to be two sets of features that help users effectively use and sort online content: tools to view, organize and navigate collections; and tools to customize and manage user-created sub-collections

A reinterpretation, and new demonstrations of, the Borel Normal Number Theorem
The notion of a normal number and the Normal Number Theorem date back over 100 years. EÌmile Borel first stated his Normal Number Theorem in 1909. Despite their seemingly basic nature, normal numbers are still engaging many mathematicians to this day. In this paper, we provide a reinterpretation of the concept of a normal number. This leads to a new proof of Borel's classic Normal Number Theorem, and also a construction of a set that contains all absolutely normal numbers. We are also able to use the reinterpretation to apply the same definition for a normal number to any point in a symbolic dynamical system. We then provide a proof that the Fibonacci system has all of its points being normal, with respect to our new definition
Single-cell profiling screen identifies microtubule-dependent reduction of variability in signaling
Populations of isogenic cells often respond coherently to signals, despite differences in protein abundance and cell state. Previously, we uncovered processes in the Saccharomyces cerevisiae pheromone response system (PRS) that reduced cell-to-cell variability in signal strength and cellular response. Here, we screened 1,141 non-essential genes to identify 50 âvariability genesâ. Most had distinct, separable effects on strength and variability of the PRS, defining these quantities as genetically distinct âaxesâ of system behavior. Three genes affected cytoplasmic microtubule function: BIM1, GIM2, and GIM4. We used genetic and chemical perturbations to show that, without microtubules, PRS output is reduced but variability is unaffected, while, when microtubules are present but their function is perturbed, output is sometimes lowered, but its variability is always high. The increased variability caused by microtubule perturbations required the PRS MAP kinase Fus3 and a process at or upstream of Ste5, the membrane-localized scaffold to which Fus3 must bind to be activated. Visualization of Ste5 localization dynamics demonstrated that perturbing microtubules destabilized Ste5 at the membrane signaling site. The fact that such microtubule perturbations cause aberrant fate and polarity decisions in mammals suggests that microtubule-dependent signal stabilization might also operate throughout metazoans.Fil: Pesce, Gustavo C..

Hydraulic control of a highly stratified estuarine front

The definitive version was published in Journal of Physical Oceanography 35 (2005): 374-387, doi:10.1175/JPO-2692.1.Observations at the mouth of the Fraser River (British Columbia, Canada) indicate an abrupt frontal transition between unstratified river outflow and a highly stratified river plume with differences in salinity greater than 25 psu across a few meters in the vertical direction and several hundred meters in the horizontal direction. The front roughly follows a natural break in the bathymetry, crossing the channel at an angle of approximately 45°, and is essentially stationary for a period of approximately 3.5 h centered on the low tide following the larger of two daily ebbs. The location of the front is coincident with observations of significantly supercritical internal Froude numbers at the front, based on velocities in the along-flow direction. This observation contradicts the one-dimensional theory, which indicates that the Froude number should be 1. However, because the front is oriented obliquely to the outflow, a coordinate system can be selected that is normal to the front and for which a critical Froude number of 1 is obtained. This indicates that a Froude angle, similar in application to a Mach angle for transonic flows, can be used to determine critical conditions when the front is oblique to the principal flow direction.This work was performed as a part of D.

The Beginning, The Middle, and The End: New Tools for the Scholarly Edition
This article discusses a set of prototypes currently being designed and created by the Interface Design team of the Implementing New Knowledge Environments (INKE) project. These prototypes attempt to supplement the user experience in reading digital scholarly editions, by supporting a set of tasks that are straightforward in a digital environment but in a print edition would be sufficiently more difficult as to be prohibitive. We therefore offer these experimental prototypes as a collection of new affordances for the scholarly edition, although they may reasonably be extended, with some variation, to other kinds of digital text
