Many of our students seem to have well-defined but not necessarily well-founded opinions on the biological effects of ionizing radiation. During discussions of nuclear transformations in introductory chemistry and physics courses we might be able to help these students better understand the magnitude of these effects, and perhaps sort out the plethora of units with which radiation measurements ...

A key advantage of interactive geovisualization tools is that users are able to quickly view data observations across multiple views. This is usually supported with a transient visual effect applied around the edges of an object during a mouse selection or rollover. This effect, commonly called highlighting, has not received much attention in geovisualization research. Today, most geovisualizat...

In 2015, community event-based surveillance (CEBS) was implemented in Sierra Leone to assist with the detection of Ebola virus disease (EVD) cases. We assessed the sensitivity of CEBS for finding EVD cases during a 7-month period, and in a 6-week subanalysis, we assessed the timeliness of reporting cases with no known epidemiologic links at time of detection. Of the 12,126 CEBS reports, 287 (2%...

The metamorphosis (commonly known as morphing) of one image into another is a well studied subject that has frequently been used to create impressive visual effects. There has been significant work recently in three-dimensional (3-D) metamorphosis, where a surface is transformed into another surface. One approach is to construct discrete volume representations of the surfaces and interpolate be...

One of the many changes in India since economic liberalisation began in 1991 is the increased use of private schooling. There has been a growing body of literature to assess whether this is a positive trend and to evaluate the effects on child achievement levels. The challenge is to identify the true private school effect on achievement, isolating the effect of the schools themselves from other...

A novel concept of the two-dimensional (2D) array of cold-electron nanobolometers (CEB) with double polarised cross-dipole antennas is proposed for ultrasensitive multimode measurements. This concept provides a unique opportunity to simultaneously measure both components of an RF signal and to avoid complicated combinations of two schemes for each polarisation. The optimal concept of the CEB in...

The cocaine- and amphetamine-regulated transcript (CART) has been the subject of significant interest for over a decade. Work to decipher the detailed mechanism of CART function has been hampered by the lack of specific pharmacological tools like antagonists and the absence of a specific CART receptor(s). However, extensive research has been devoted to elucidate the role of the CART peptide and...

Empirical analyses in political science very commonly confront data that are grouped— multiple votes by individual legislators, multiple years in individual states, multiple conflicts during individual years, and so forth. Modeling these data presents a series of potential challenges, of which accounting for differences across the groups is perhaps the most well-known. Two widely-used methods a...

A convenient approach to small-x evolution in QCD is the dipole picture which was formulated by Mueller a decade ago [1–3]. Mueller’s formalism leads to the BFKL equation but it also goes beyond the BFKL formalism, since here it is possible to take into account unitarisation effects due to multiple scatterings (multiple pomeron exchanges). In Mueller’s model dipoles in the same cascade (wavefun...
