… For instance, k-fold cross-validation divides the dataset into k parts, with one part used as a
test set and the rest as training sets, which can reduce training data loss and obtain relatively …

… (γ) phase was detected at 100 K, and the phase transition between the tetragonal (β) phase
and orthorhombic (γ) phase occurs at around 160 K; the atomic structure for these three …

Improving the long-term stability of perovskite solar cells is critical to the deployment of this
technology. Despite the great emphasis laid on stability-related investigations, publications …

Background With the unprecedented morbidity and mortality associated with the COVID-19
pandemic, a vaccine against COVID-19 is urgently needed. We investigated CoronaVac (…

… By the Theorem 3, we calculate V(S k ij ⩾S k j ), j=1,2,…,n k , j≠i and(4) P k ih (A k i )= min

The true programmed mechanisms of delayed neuronal death induced by global cerebral
ischemia/reperfusion injury remain incompletely characterized. Autophagic cell death and …

OBJECTIVE: Current biomarkers cannot completely distinguish sepsis from systemic
inflammatory response syndrome (SIRS) caused by other non-infectious diseases. Circulating …

Raman characterization of aligned carbon nanotubes of average diameter 10–15 nm,
produced by chemical vapor deposition on a mesoporous substrate, has been carried out. The …

Activation of tetrodotoxin-resistant sodium channels contributes to action potential electrogenesis
in neurons. Antisense oligonucleotide studies directed against Na v 1.8 have shown …

… See Tables 1 and 2 for agonist concentrations and derived K i values. (C) Representative …
K i values were estimated by the equation: K i = IC 50 /(1 + [agonist]/agonist EC 50 ) (19). …
