Determining the rp-process flow through 56Ni: resonances in 57Cu(p,γ)58Zn identified with GRETINA.

Physical review letters

Langer C, Montes F, Aprahamian A, Bardayan DW, Bazin D, Brown BA, Browne J, Crawford H, Cyburt RH, Domingo-Pardo C, Gade A, George S, Hosmer P, Keek L, Kontos A, Lee IY, Lemasson A, Lunderberg E, Maeda Y, Matos M, Meisel Z, Noji S, Nunes FM, Nystrom A, Perdikakis G, Pereira J, Quinn SJ, Recchia F, Schatz H, Scott M, Siegl K, Simon A, Smith M, Spyrou A, Stevens J, Stroberg SR, Weisshaar D, Wheeler J, Wimmer K, Zegers RG.
PMID: 25083636
Phys Rev Lett. 2014 Jul 18;113(3):032502. doi: 10.1103/PhysRevLett.113.032502. Epub 2014 Jul 14.

An approach is presented to experimentally constrain previously unreachable (p, γ) reaction rates on nuclei far from stability in the astrophysical rp process. Energies of all critical resonances in the (57)Cu(p,γ)(58)Zn reaction are deduced by populating states in (58)Zn...

Preparation and comparison of biological properties of recombinant carp (Cyprinus carpio) growth hormone and its Cys-123 to Ala mutant.

Fish physiology and biochemistry

Fine M, Sakal E, Vashdi D, Chapnik-Cohen N, Daniel V, Levanon A, Lipshitz O, Gertler A.
PMID: 24202495
Fish Physiol Biochem. 1993 Jul;11(1):353-61. doi: 10.1007/BF00004585.

Carp growth hormone (cGH) cDNA, in which Cys-123 was mutated to Ala, was prepared, transferred to the expression vector, expressed in Escherichia coli and the mutant was purified to homogeneity. The mutation only slightly improved yield of the monomeric...

Measuring complexity in organisms and organizations.

Rebout N, Lone JC, De Marco A, Cozzolino R, Lemasson A, Thierry B.
PMID: 33959307
R Soc Open Sci. 2021 Mar 17;8(3):200895. doi: 10.1098/rsos.200895.

While there is no consensus about the definition of complexity, it is widely accepted that the ability to produce uncertainty is the most prominent characteristic of complex systems. We introduce new metrics that purport to quantify the complexity of...

Social pressure drives "conversational rules" in great apes.

Biological reviews of the Cambridge Philosophical Society

Pougnault L, Levréro F, Leroux M, Paulet J, Bombani P, Dentressangle F, Deruti L, Mulot B, Lemasson A.
PMID: 34873806
Biol Rev Camb Philos Soc. 2021 Dec 06; doi: 10.1111/brv.12821. Epub 2021 Dec 06.

In the last decade, two hypotheses, one on the evolution of animal vocal communication in general and the other on the origins of human language, have gained ground. The first hypothesis argues that the complexity of communication co-evolved with...

High-resolution multi-scan compact Fourier transform-infrared spectrometer.

Optics letters

Lifshitz E, Arieli U, Katz S, Nir I, Levanon A, Mrejen M, Suchowski H.
PMID: 31199397
Opt Lett. 2019 Jun 15;44(12):3126-3129. doi: 10.1364/OL.44.003126.

The Fourier transform-infrared (FT-IR) spectrometer is a widely used high-resolution spectral characterization method in materials, chemicals, and more. However, the inverse relation between the spectral resolution and the interferometer's arm length yields a tradeoff between spectral resolution and spectrometer...

Isospin Symmetry at High Spin Studied via Nucleon Knockout from Isomeric States.

Phys Rev Lett. 2016 Aug 19;117(8):082502. doi: 10.1103/PhysRevLett.117.082502. Epub 2016 Aug 15.

One-neutron knockout reactions have been performed on a beam of radioactive ^{53}Co in a high-spin isomeric state. The analysis is shown to yield a highly selective population of high-spin states in an exotic nucleus with a significant cross section,...

Direct observation of soliton and normal pulse propagation by spectral domain reflectometry.

Optics letters

Levanon A, Friberg SR, Mukai T, Fujii Y.
PMID: 19876239
Opt Lett. 1996 Jul 15;21(14):1023-5. doi: 10.1364/ol.21.001023.

We report what are to our knowledge the first continuous observations of optical fiber solitons and nonsoliton pulses in the spectral domain. Using a novel optical time-resolved spectral ref lectometer that measures the backscattered light spectrum, we directly observed...

Sex Differences in Language Across Early Childhood: Family Socioeconomic Status does not Impact Boys and Girls Equally.

Frontiers in psychology

Barbu S, Nardy A, Chevrot JP, Guellaï B, Glas L, Juhel J, Lemasson A.
PMID: 26696938
Front Psychol. 2015 Dec 02;6:1874. doi: 10.3389/fpsyg.2015.01874. eCollection 2015.

Child sex and family socioeconomic status (SES) have been repeatedly identified as a source of inter-individual variation in language development; yet their interactions have rarely been explored. While sex differences are the focus of a renewed interest concerning emerging...

Epic Allies: Development of a Gaming App to Improve Antiretroviral Therapy Adherence Among Young HIV-Positive Men Who Have Sex With Men.

BACKGROUND: In the United States, the human immunodeficiency virus (HIV) disproportionately affects young men who have sex with men (YMSM). For HIV-positive individuals, adherence to antiretroviral therapy (ART) is critical for achieving optimal health outcomes and reducing secondary transmission...

Pulse shaping of broadband adiabatic SHG from a Ti-sapphire oscillator.

Optics letters

Levanon A, Dahan A, Nagler A, Lifshitz E, Bahar E, Mrejen M, Suchowski H.
PMID: 28957227
Opt Lett. 2017 Aug 01;42(15):2992-2995. doi: 10.1364/OL.42.002992.

We experimentally demonstrate an efficient broadband second-harmonic generation (SHG) process with a tunable mode-locked Ti:sapphire oscillator. We have achieved a robust broadband and efficient flat conversion of more than 35 nm wavelength by designing an adiabatic aperiodically poled potassium...

Oncotarget. 2019 Jul 09;10(43):4407-4423. doi: 10.18632/oncotarget.27034. eCollection 2019 Jul 09.

Dicer, an endoribonuclease best-known for its role in microRNA biogenesis and RNA interference pathway, has been shown to play a role in the DNA damage response and repair of double-stranded DNA breaks (DSBs) in mammalian cells. However, it remains...
