Matteazzi E, Perali F.
GSID: LLRv92T2YRsJ
E Matteazzi, M Menon, F Perali - 2021 - ideas.repec.org

This paper investigates the role of effort on mathematics performance of boys and girls, an aspect that may contribute to our understanding of the gender gap in science, technology, engineering and math (STEM) fields in college. We exploit a...

The spontaneous synchronized dance of pairs of water molecules.

DOCK 8 Deficiency, EBV+ Lymphomatoid Granulomatosis, and Intrafamilial Variation in Presentation.

Frontiers in pediatrics

Dimitriades VR, Devlin V, Pittaluga S, Su HC, Holland SM, Wilson W, Dunleavy K, Shah NN, Freeman AF.

Front Pediatr. 2017 Feb 28;5:38. doi: 10.3389/fped.2017.00038. eCollection 2017.

Dedicator of cytokinesis 8 (DOCK8) deficiency is an autosomal recessive, combined immunodeficiency within the spectrum of hyper-IgE syndromes. Epstein-Barr virus-positive lymphomatoid granulomatosis (LYG) (EBV + LYG) is a rare diagnosis and a previously unreported presentation of DOCK8 deficiency. A...

Orientation of benzene in supersonic expansions, probed by IR-laser absorption and by molecular beam scattering.

Physical review letters

Pirani F, Cappelletti D, Bartolomei M, Aquilanti V, Scotoni M, Vescovi M, Ascenzi D, Bassi D.
PMID: 11384414
Phys Rev Lett. 2001 May 28;86(22):5035-8. doi: 10.1103/PhysRevLett.86.5035.

This work represents the first experimental demonstration that planar molecules tend to travel as a "frisbee" when a gaseous mixture with lighter carriers expands into a vacuum, the orientation being due to collisions. The molecule is benzene, the prototype...

The spin-orbit and rotational constants for the N2 C" 5Pi(ui) (v = 3) state.

The Journal of chemical physics

Field RW, Pirali O, Tokaryk DW.
PMID: 16512697
J Chem Phys. 2006 Feb 28;124(8):081103. doi: 10.1063/1.2172919.

The spin-orbit (A = -16.4 cm(-1)) and rotational (B = 1.017 cm(-1)) constants for the N2 C" 5Pi(ui)(v = 3) level are determined by a fit to rotational lines in the C" 5Pi(u)-A' 5Sigma(g)+(3-1) band that terminate in J'Omega'...
