The Mars 2020 mission will seek the signs of ancient life on Mars and will identify, prepare,
document, and cache a set of samples for possible return to Earth by a follow-on mission. …

Crucial transitions in cancer—including tumor initiation, local expansion, metastasis, and
therapeutic resistance—involve complex interactions between cells within the dynamic tumor …

The selectin family of adhesion molecules mediates the initial attachment of leukocytes to
venular endothelial cells before their firm adhesion and diapedesis at sites of tissue injury and …

We study B→ K (*) ℓ+ ℓ− decays (ℓ= e, μ) based on a data sample of 657× 10 6 BB pairs
collected with the Belle detector at the KEKB e+ e− collider. We report the differential branching …

The cross section for e+ e−→ π+ π− J/ψ between 3.8 and 5.5 GeV/c 2 is measured using a
548 fb− 1 data sample collected on or near the Υ (4 S) resonance with the Belle detector at …

A precision measurement by the Alpha Magnetic Spectrometer on the International Space
Station of the positron fraction in primary cosmic rays in the energy range from 0.5 to 350 GeV …

The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S)
events in its decade of operation. Super-KEKB, an upgrade of KEKB is under construction, …

We report a measurement of the branching fraction ratios R (D (*)) of B→ D (*) τ− ν τ relative
to B→ D (*) ℓ− ν ℓ (where ℓ= e or μ) using the full Belle data sample of 772× 10 6 BB pairs …

The cross section for e+ e−→ π+ π− ψ (2 S) between threshold and s= 5.5 GeV is measured
using 673 fb− 1 of data on and off the Υ (4 S) resonance collected with the Belle detector at …

We present a measurement of angular observables and a test of lepton flavor universality in
the B→ K* ℓ+ ℓ− decay, where ℓ is either e or μ. The analysis is performed on a data sample …
