Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Level densities in nuclear physics [PDF]
, 1978 In the independent-particle model nucleons move independently in a central potential. There is a well-defined set of single- particle orbitals, each nucleon occupies one of these orbitals subject to Fermi statistics, and the total energy of the nucleus is equal to the sum of the energies of the individual nucleons.

Direct evidence of fadeout of collective enhancement in nuclear level density
Physics Letters B, 2017 The phenomenon of collective enhancement in nuclear level density and its fadeout has been probed using neutron evaporation study of two strongly deformed (173Lu, 185Re), and one spherical (201Tl) compound nuclei over the excitation energy (E⁎) range of ∼

New density-independent interactions for nuclear structure calculations [PDF]
, 2013 We present a new two-body finite-range and momentum-dependent but density-independent effective interaction, which can be interpreted as a regularized zerorange force.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Nuclear level density with proton resonance using Gaussian orthogonal ensemble theory
Iraqi Journal of Physics, 2019 The Gaussian orthogonal ensemble (GOE) version of the random matrix theory (RMT) has been used to study the level density following up the proton interaction with 44Ca, 48Ti and 56Fe.

Combinatorial nuclear level-density model [PDF]
, 2008 A microscopic nuclear level-density model is presented. The model is a completely combinatorial (micro-canonical) model based on the folded-Yukawa single-particle potential and includes explicit treatment of pairing, rotational and vibrational states ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Discrete Levels Density and Spin Cut off Parameters of the 36Cl, 40K, 60Co and 61Ni Nucleuses [PDF]
مجله علوم و فنون هستهای, 2010 On the bases of Bethe and the constant temperature models, the level density parameters have been calculated for the 36Cl, 40K, 60Co and 61Ni nuclei, nucleuses through fitting the complete level schemes in low excitation energy levels.

EPJ Web of ConferencesNuclear reaction models, and in particular compound nucleus reactions, require the knowledge of nuclear level densities (NLDs), among other ingredients. For decades, analytical expressions have been used in nuclear reaction codes, due to the freedom they offer to the user to modify their associated parameters in order to fit cross sections.
