Prevention of fertilization by exposure of hamster eggs to soluble acrosin [PDF]
, 1977 Incubation of hamster eggs with trypsin or chymotrypsin, but not with a series of glycosidases or lipases, prevents capacitated spermatozoa from binding to the zona pellucida so that fertilization is prevented (Hartmann & Gwatkin, 1971; Gwatkin ...

Theoretical Population Biology, 1987 Abstract The standard models of selfing in seed plants consider only the ovules, which are assumed to have a constant selfing rate. It has recently become clear, however, that hermaphrodite or monoecious populations frequently show sexual asymmetry (nonconstant pollen:ovule fertilities among individuals).

Advanced Science, EarlyView.Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates
Advanced Science, EarlyView.Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

PLoS ONE, 2019 Leeches and oligochaetes comprise a monophyletic group of annelids, the Clitellata, whose reproduction is characterized by simultaneous hermaphroditism. While most clitellate species reproduce by cross-fertilization, self-fertilization has been described

, 2006 There is a longstanding debate in the self-concept literature surrounding the causal ordering of self-concept and academic achievement. Some researchers have argued that self-esteem has no positive impact upon performance (Baumeister, Campbell, Krueger &
