Substorms generally inject tens to hundreds of keV electrons, but intense substorm electric fields have been shown to inject MeV electrons as well. An intriguing question is whether such MeVelectron injections can populate the outer radiation belt. Here we...

EVOLUTION AND POPULATION STRUCTURE OF AFRICANIZED HONEY BEES IN BRAZIL: EVIDENCE FROM SPATIAL ANALYSIS OF MORPHOMETRIC DATA.

Evolution; international journal of organic evolution

Diniz-Filho JAF, Malaspina O.
PMID: 28568529
Evolution. 1995 Dec;49(6):1172-1179. doi: 10.1111/j.1558-5646.1995.tb04444.x.

In recent years, studies based on isoenzymatic patterns of geographic variation have revealed that what is usually called the Africanized honey bee does not constitute a single population. Instead, several local populations exist with various degrees of admixture with...

We report observations from the Magnetospheric Multiscale satellites of parallel electric fields (E_{∥}) associated with magnetic reconnection in the subsolar region of the Earth's magnetopause. E_{∥} events near the electron diffusion region have amplitudes on the order of 100...

Peculiar Aqueous Solubility Trend in Cucurbiturils Unraveled by Atomistic Simulations.

The journal of physical chemistry. B

Malaspina T, Fileti E, Chaban VV.
PMID: 27409242
J Phys Chem B. 2016 Aug 04;120(30):7511-6. doi: 10.1021/acs.jpcb.6b05425. Epub 2016 Jul 27.

Cucurbiturils (CBs) compose a family of macrocycles whose elementary unit is glycouril (GLYC). CBs are of high interest in chemistry and biology due to their versatile applications, ranging from sensors to advanced drug-delivery systems. Here, we report a systematic...

CSF neurofilament light chain reflects corticospinal tract degeneration in ALS.

Annals of clinical and translational neurology

Schizophrenia risk and paternal age: a potential role for de novo mutations in schizophrenia vulnerability genes.

CNS spectrums
