Advances in molecular profiling have opened up the possibility to map the expression of genes in cells, tissues, and organs in the human body. Here, we combined single-cell transcriptomics analysis with spatial antibody-based protein profiling to create a high-resolution single–cell type map of human tissues. An open access atlas has been launched to allow researchers to explore the expression of human protein-coding genes in 192 individual cell type clusters. An expression specificity classification was performed to determine the number of genes elevated in each cell type, allowing comparisons with bulk transcriptomics data. The analysis highlights distinct expression clusters corresponding to cell types sharing similar functions, both within the same organs and between organs.
Focal mechanism and slip history of the 2011 M w 9.1 off the Pacific coast of Tohoku, Japan earthquake were derived rapidly from teleseismic body and surface waves. Multiple double couples (MDC) analysis was first conducted using 1-hour long period seismic waves, yielding a single double couple with a seismic moment of 5.06×10 22 N m, whose low angle nodal plane orients 199 • and dips 10 • west. Spatiotemporal rupture history was then constrained using both broadband body waves and long period seismic waves. The solution was updated twice in three days. Our preferred model, which based on the MDC fault plane, local JMA hypocenter and calibrated alignments of body and surface waves, revealed a complex rupture process. The rupture initiated slowly at a depth of 23 km. It first propagated in downdip and bilaterally directions along the subduction interface for 45 s and then broke a 80 km by 250 km near trench asperity in the up-dip direction and produced up to 60 m slip. The fault plane below the hypocenter had two more subevents, occurring in 70-95 s and 110-160 s, respectively. The total seismic moment was 5.8 × 10 22 N m. The abnormal high slip near the trench suggests a recurrence interval larger than 500 yr.
Radiative cooling is a passive cooling
technology that offers great
promises to reduce space cooling cost, combat the urban island effect,
and alleviate the global warming. To achieve passive daytime radiative
cooling, current state-of-the-art solutions often utilize complicated
multilayer structures or a reflective metal layer, limiting their
applications in many fields. Attempts have been made to achieve passive
daytime radiative cooling with single-layer paints, but they often
require a thick coating or show partial daytime cooling. In this work,
we experimentally demonstrate remarkable full-daytime subambient cooling
performance with both BaSO4 nanoparticle films and BaSO4 nanocomposite paints. BaSO4 has a high electron
band gap for low solar absorptance and phonon resonance at 9 μm
for high sky window emissivity. With an appropriate particle size
and a broad particle size distribution, the BaSO4 nanoparticle
film reaches an ultrahigh solar reflectance of 97.6% and a high sky
window emissivity of 0.96. During field tests, the BaSO4 film stays more than 4.5 °C below ambient temperature or achieves
an average cooling power of 117 W/m2. The BaSO4-acrylic paint is developed with a 60% volume concentration to enhance
the reliability in outdoor applications, achieving a solar reflectance
of 98.1% and a sky window emissivity of 0.95. Field tests indicate
similar cooling performance to the BaSO4 films. Overall,
our BaSO4-acrylic paint shows a standard figure of merit
of 0.77, which is among the highest of radiative cooling solutions
while providing great reliability, convenient paint form, ease of
use, and compatibility with the commercial paint fabrication process.
