Leggett collective excitations in a two-band Fermi superfluid at finite temperatures

New Journal of Physics, 2019
The Leggett collective excitations for a two-band Fermi gas with s -wave pairing and Josephson interband coupling in the BCS-BEC crossover at finite temperatures are investigated within the Gaussian pair fluctuation approach. Eigenfrequencies and damping

Dissipative charged fluid in a magnetic field

Physics Letters B, 2016
We study the collective excitations in a dissipative charged fluid at zero chemical potential when an external magnetic field is present. While in the absence of magnetic field, four collective excitations appear in the fluid, we find five hydrodynamic ...

Supersymmetry And Electron-hole Excitation in Semiconductor At Finite Temperature

, 1996
The fermionic and bosonic electron-hole low lying excitations in a semiconductor are analyzed at finite temperature in a unified way following Nambu's quasi-supersymmetric approach for the BCS model of superconductivity.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Conserved Quantities in Background Independent Theories [PDF]

, 2007
We discuss the difficulties that background independent theories based on quantum geometry encounter in deriving general relativity as the low energy limit.

NKCC1: A key regulator of glioblastoma progression

Molecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Collective charge excitations along cell membranes

, 2004
A significant part of the thin layers of counter-ions adjacent to the exterior and interior surfaces of a cell membrane form quasi-two-dimensional (2D) layers of mobile charge.

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Detection of collective optic excitations in molten NaI

Condensed Matter Physics, 2019
High-resolution inelastic x-ray scattering measurements were carried out on molten NaI near the melting point at 680°C at SPring-8. Small and damped indications of longitudinal optic excitation modes were observed on the tails of the longitudinal ...

Inelastic scattering reaction as a probe for monopole, dipole and quadrupole excitations [PDF]

EPJ Web of Conferences
The study of collective motions within atomic nuclei, such as monopole, dipole, and quadrupole excitations, is crucial for understanding nuclear structure and properties, which provide insights into the spatial distribution and dynamic nature of protons ...
