[1] The geometry and properties of the interface of the Cocos plate beneath central Mexico are determined from the receiver functions (RFs) utilizing data from the Meso America Subduction Experiment (MASE). The RF image shows that the subducting oceanic crust is shallowly dipping to the north at 15° for 80 km from Acapulco and then horizontally underplates the continental crust for approximatel...

Let f(n, p, q) be the minimum number of colors necessary to color the edges of Kn so that every Kp is at least q-colored. We improve current bounds on these nearly “anti-Ramsey” numbers, first studied by Erdős and Gyárfás. We show that f(n, 5, 9) ≥ 7 4 n− 3, slightly improving the bound of Axenovich. We make small improvements on bounds of Erdős and Gyárfás by showing 5 6 n+1 ≤ f(n, 4, 5) and f...

Abstract Background The lateral craniopharyngeal canal or Sternberg’s is located in the postero-lateral part of sphenoid sinus. It weakest area skull base, originating due to defective fusion during embryological development a small proportion individuals. Hence, it can give rise CSF leaks from that region. Due proximity this region internal carotid artery, optic nerve, and cavernous sinus, pro...

The existence of cosmic rays transcending the Greisen-Zatsepin-Kuzmin (GZK) cutoff appear to be a fact of life. While there is still some controversy regarding the observational data, it appears that opinions converge toward acknowledging the existence of trans-GZK events. Clearly, the issue will be satisfactorily clarified once future detectors, such as OWL, EUSO, the Pierre Auger Observatory,...

In humans the steroid 5alpha-reductase (SRD5A) family comprises five integral membrane enzymes that carry out reduction of a double bond in lipidic substrates: Δ4-3-keto steroids, polyprenol and trans-enoyl CoA. The best-characterized reaction is the conversion of testosterone into the more potent dihydrotestosterone carried out by SRD5A1-2. Some controversy exists on their possible nuclear or ...

Abstract This paper analyses the Australian children’s picture books The Gender Fairy , by Jo Hirst and Libby Wirt, Introducing Teddy: A Gentle Story About Friendship Jess Walton Dougal MacPherson. Both are examples of a rare engagement authors illustrators; indeed, has distinction being first author book with trans protagonist. illustrators engage issues within socio-political context that con...
