Extra-Large Remnant Recoil Velocities and Spins from Near-Extremal-Bowen-York-Spin Black-Hole Binaries [PDF]

open access: yes, 2008
We evolve equal-mass, equal-spin black-hole binaries with specific spins of a/mH 0.925, the highest spins simulated thus far and nearly the largest possible for Bowen-York black holes, in a set of configurations with the spins counter-aligned and ...

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

A signature of the donor star in the extra-galactic X-ray binary LMC X-2 [PDF]

open access: yes, 2007
Two nights of phase-resolved medium-resolution Very Large Telescope spectroscopy of the extra-galactic low-mass X-ray binary LMCX-2 have revealed a 0.32 +/- 0.02 d spectroscopic period in the radial velocity curve of the He II lambda 4686 emission line ...

FOCUS: A Four‐In‐One Consolidated Unison Strain Sensor with Enhanced Sensitivity

open access: yesAdvanced Science, EarlyView.
Through a folding transformation that stacks four printed liquid metal sensors into a unified 3D orthogonal construct, FOCUS harnesses complementary bidirectional resistance responses within a Wheatstone bridge. This architecture yields fivefold sensitivity enhancement and 25 µm resolution, overcoming LM sensors’ micro‐strain limitations and enabling ...

Trumpet Initial Data for Boosted Black Holes [PDF]

open access: yes, 2018
We describe a procedure for constructing initial data for boosted black holes in the moving-punctures approach to numerical relativity that endows the initial time slice from the outset with trumpet geometry within the black hole interiors.

BHLHE40 Orchestrates Effector Tissue‐Resident Memory CD8+ T Cells and Limits Long‐Term Survival of Kidney Graft

open access: yesAdvanced Science, EarlyView.
An effector subset of TRM, defined as CD49a+PD1hi CD8+ TRM, represents a BHLHE40‐orchestrated resident immune component that, rather than circulating cells, plays as a major contributor to allograft rejection. ABSTRACT Tissue‐resident memory T cells (TRM), which function against tumors, infections, and non‐self antigens in organ transplantation ...

Evapotranspiração do capim Tanzânia obtida pelo método de razão de Bowen e lisímetro de pesagem Evapotranspiration of Guinea grass using automated Bowen ratio system and lysimeter

open access: yesEngenharia Agrícola, 2005
A irrigação de pastagens no Brasil apresentou crescimento acentuado nos últimos anos. No entanto, em função da ausência de pesquisas sobre a aplicação de água em pastagens, o manejo da irrigação não vem sendo realizado de maneira racional. Com o objetivo

Atmospheric Boundary-Layer Dynamics with Constant Bowen Ratio [PDF]

open access: yes, 2018
Motivated by the observation that the diurnal evolution of sensible and latent heat fluxes tends to maintain a constant Bowen ratio, we derive approximate solutions of the ordinary differential equations of a simplified atmospheric boundary-layer (ABL ...

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

open access: yesAdvanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...
