Abstract “A Craftsman Must Sharpen His Tools to Do Job,” said Confucius. Nuclear detection and readout techniques are the foundation of particle physics, nuclear astrophysics reveal nature universe. Also, they being increasingly used in other disciplines like power generation, life sciences, environmental medical etc. The article reviews short history, recent development, trend techniques, covering Semiconductor Detector, Gaseous Scintillation Cherenkov Transition Radiation Readout...
Most related research focuses on a single variable of verbal and nonverbal behaviors independently without considering their associations. Therefore, it is important to understand subclinical depression in the entire population. This study investigated cross-modal co-occurrence behavior with vocal emotions, prosody, content words individuals depression. A total 70 participants assigned control groups participated structured interviews. Elan software was used layer, transcribe, annotate...
A dedicated measurement of additional radiation in e+e−→μ+μ−γ and e+e−→π+π−γ initial-state-radiation events is presented using the full BABAR data sample. For first time results are at next-to- next-to-next-to-leading order, with one two photons, respectively, for from initial final states. Comparison predictions phokhara afkqed Monte Carlo generators performed, revealing discrepancies one-photon rates angular distributions former. This disagreement has a negligible effect on e+e−→π+π−(γ)...

Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below electroweak scale. In presence couplings to bosons, these could emitted flavor-changing B meson decays.
