An alternative hypothesis on the origin of the Greek alphabet
Kervan. International Journal of Afro-Asiatic Studies, 2023 Did the Greeks learn the alphabet directly from the Phoenicians or did they learn it from non-Semitic intermediaries? Were these intermediaries the Phrygians or did the Phrygians learn it from the Greeks or some other people?

The canalization hypothesis – challenges and alternatives [PDF]
New Phytologist, 2020 SummaryThe ‘canalization hypothesis’ was suggested 50 years ago by Tsvi Sachs to account for the formation of vascular strands in response to wounding or auxin application. The hypothesis proposes that positive feedback between auxin movement through a cell and the cell's auxin conductivity leads to the gradual selection of narrow ‘canals’ of polar ...

HIGHER CORRELATIONS AND THE ALTERNATIVE HYPOTHESIS [PDF]
The Quarterly Journal of Mathematics, 2020 AbstractThe Alternative Hypothesis (AH) concerns a hypothetical and unlikely picture of how zeros of the Riemann zeta function are spaced, which one would like to rule out. In the Alternative Hypothesis, the renormalized distance between non-trivial zeros is supposed to always lie at a half integer.

Vitamin D: The alternative hypothesis [PDF]
Autoimmunity Reviews, 2009 Early studies on vitamin D showed promise that various forms of the "vitamin" may be protective against chronic disease, yet systematic reviews and longer-term studies have failed to confirm these findings. A number of studies have suggested that patients with autoimmune diagnoses are deficient in 25-hydroxyvitamin D (25-D) and that consuming greater ...

Crossings as a side effect of dependency lengths [PDF]
, 2016 The syntactic structure of sentences exhibits a striking regularity: dependencies tend to not cross when drawn above the sentence. We investigate two competing explanations.

Revisiting the two-layer hypothesis: coexistence of alternative functional rooting strategies in savannas. [PDF]
PLoS ONE, 2013 The two-layer hypothesis of tree-grass coexistence posits that trees and grasses differ in rooting depth, with grasses exploiting soil moisture in shallow layers while trees have exclusive access to deep water.
