Temperature-tunable topological zero-refraction acoustic metamaterials

Frontiers in Materials
Zero-refractive index metamaterials have a wide range of applications in directional transmission and wave-front shaping due to their unusual acoustic properties.

Meson loop effects in the NJL model at zero and non-zero temperature

, 2000
We compare two different possibilities to include meson-loop corrections in the Nambu-Jona-Lasinio model: a strict 1/N_c-expansion in next-to-leading order and a non-perturbative scheme corresponding to a one-meson-loop approximation to the effective ...

A conjecture on the relationship between critical residual entropy and finite temperature pseudo-transitions of one-dimensional models

, 2020
Recently pseudo-critical temperature clues were observed in one-dimensional spin models, such as the Ising-Heisenberg spin models, among others. Here we report a relationship between the zero-temperature phase boundary residual entropy (critical residual

Lattice QCD at finite isospin density at zero and finite temperature [PDF]

, 2002
We simulate lattice QCD with dynamical $u$ and $d$ quarks at finite chemical potential, $\mu_I$, for the third component of isospin ($I_3$), at both zero and at finite temperature. At zero temperature there is some $\mu_I$, $\mu_c$ say, above which $I_3$

LIOUVILLE COSMOLOGY AT ZERO AND FINITE TEMPERATURES [PDF]

International Journal of Modern Physics A, 2006
We discuss cosmology in the context of Liouville strings, characterized by a central-charge deficit Q2, in which target time is identified with (the worldsheet zero mode of the) Liouville field: Q-Cosmology. We use a specific example of colliding braneworlds to illustrate the phase diagram of this cosmological framework.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Rheology across the Zero-Temperature Jamming Transition [PDF]

Physical Review Letters, 2013
Many soft-matter systems show a transition between fluidlike and mechanically solidlike states when the volume fraction of the material, e.g., particles, drops, or bubbles is increased. Using an emulsion as a model system with a precisely controllable volume fraction, we show that the entire mechanical behavior in the vicinity of the jamming point can ...

Taking Earth’s Temperature: Will Zero Carbon Mean Zero Change?

Frontiers for Young Minds, 2023
How do we stop global warming? We know that excess carbon dioxide (CO2) in the atmosphere causes global warming, but when we stop emitting CO2–a goal known as net zero—will warming stop at the same time? Our best understanding is that no more CO2 emissions means no more warming, but we are not completely sure about this. The extra change in temperature

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

Molecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

The Universality and stability for a dilute Bose gas with a Feshbach resonance

, 2010
We study the bosonic atoms with a wide Feshbach resonance at zero temperature in terms of the renormalization group. We indicate that this system will always collapse in the dilute limit.
