A new polymorph of phenylselenium trichloride
(International Union of Crystallography, 2019-11)A second polymorph of phenylselenium trichloride, PhSeCl3 or C6H5Cl3Se, is disclosed, which is comprised of asymmetric chlorine-bridged noncovalent dimer units rather than polymeric chains. These dimers are each weakly ... -
New Radiometric Ages for the BH-1 Hominin from Balanica (Serbia): Implications for Understanding the Role of the Balkans in Middle Pleistocene Human Evolution
(PLoS, 2013-02-06)Newly obtained ages, based on electron spin resonance combined with uranium series isotopic analysis, and infrared/postinfrared luminescence dating, provide a minimum age that lies between 397 and 525 ka for the hominin ... -
A new staples industry? Complexity, governance and Canada's diamond mines
(Oxford University Press, 2007)The discovery of indicator minerals in the Slave geological province began a staking and development rush that, in a little over a decade, saw Canada becoming one of the world’s largest producers of diamonds. An examination ... -

Nitrogen and phosphorus loads to temperate seepage lakes associated with allochthonous dissolved organic carbon loads
(American Geophysical Union, 2018-06-16)Terrestrial loads of dissolved organic matter (DOM) have increased in recent years in many north temperate lakes. While much of the focus on the “browning” phenomena has been on its consequences for carbon cycling, much ... -
Nitrogen dynamics and nitrogen-to-phosphorus stoichiometry in cold region agricultural streams
(Wiley Periodicals LLC on behalf of American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2021-05-12)Cold agricultural regions are getting warmer and experiencing shifts in precipitation patterns, which affect hydrological transport of nutrients through reduced snowpack and higher annual proportions of summer rainfall. ... -
‘‘No place like home’’: the facts and figures of homelessness in contemporary texts for young people
(2013)The most common story for children is one in which a central character leaves home in search of an adventure or is pushed out of an originary home, journeys to an unfamiliar place, and, after a series of exciting and/or ... -
Non repetitive walks in graphs and digraphs
(The University of CalgaryUniversity of Calgary, 1987-06)A word $w$ over alphabet $\Sigma$ is {\em non-repetitive} if we cannot write $w=abbc$, $a,b,c\in\Sigma^*$, $b\ne\epsilon$. That is, no subword of $w$ appears twice in a row in $w$. In 1906, Axel Thue, the Norwegian number ... -
Non-Repetitive Tilings
(The Electronic Journal of Combinatorics, 2002-07-03)In 1906 Axel Thue showed how to construct an infinite non-repetitive (or square-free) word on an alphabet of size 3. Since then this result has been rediscovered many times and extended in many ways. We present a two-dimensional ... -

(PLoS, 2016-04-12)Dental modifications in the Caribbean are considered to be an African practice introduced to the Caribbean archipelago by the influx of enslaved Africans during colonial times. Skeletal remains which exhibited dental ... -
A Note on Antichains of Words
(The Electronic Journal of Combinatorics, 1995-10-14)We can compress the word 'banana' as xyyz, where x= 'b', y= 'an',z= 'a'. We say that 'banana' encounters yy. Thus a 'coded' version of yy shows up in 'banana'. The relation 'u encounters w' is transitive, and thus generates ... -

The number of order–preserving maps of fences and crowns
(Springer, 1991-06)We perform an exact enumeration of the order-preserving maps of fences (zig-zags) and crowns (cycles). From this we derive asymptotic results. -
The Number of Ternary Words Avoiding Abelian Cubes Grows Exponentially
(2004-06-19)We show that the number of ternary words of length n avoiding abelian cubes grows faster than r^n, where r = 2^{1/24}
