Malaria climbs the mountain

Malaria continues to be a scourge of many tropical countries and climate change seems to be adding to the problem. A seven-fold increase in cases of malaria on the slopes of Mount Kenya have been found by a team of Kenyan and British researchers. A 2ºC increase in average temperatures around the mountain in the past 20 years has allowed the disease to creep into higher-altitude areas, where the...

Gets drunk, climbs buildings

As you suggest, bounding up buildings is probably not the safest idea, particularly when you've had a few drinks. So, short of doing your drinking in the middle of a nice, flat field, two ideas you might consider come to mind: (1) drink with trusted friends who will keep an eye on you, and (2) take a look at your drinking habits with an eye on what motivates your behavior. For safety's sake, yo...

The ranks of the classes of $A_{10}$

‎Let $G $ be a finite group and $X$ be a conjugacy class of $G.$ The‎ ‎rank of $X$ in $G,$ denoted by $rank(G{:}X),$ is defined to‎ ‎be the minimal number of elements of $X$ generating $G.$ In this‎ ‎paper we establish the ranks of all the conjugacy classes of‎ ‎elements for simple alternating group $A_{10}$ using the structure‎ ‎constants method and other results established in‎ ‎[A.B.M‎. ‎Bas...

On the Ranks and Border Ranks of Symmetric Tensors

Motivated by questions arising in signal processing, computational complexity, and other areas, we study the ranks and border ranks of symmetric tensors using geometric methods. We provide improved lower bounds for the rank of a symmetric tensor (i.e., a homogeneous polynomial) obtained by considering the singularities of the hypersurface defined by the polynomial. We obtain normal forms for po...
