A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

open access: yesAdvanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...

A flexible and generalizable model of online latent-state learning.

open access: yesPLoS Computational Biology, 2019
Many models of classical conditioning fail to describe important phenomena, notably the rapid return of fear after extinction. To address this shortfall, evidence converged on the idea that learning agents rely on latent-state inferences, i.e. an ability

Brief of Professors William Baude and Stephen E. Sachs as Amici Curiae in Support of Neither Party [PDF]

open access: yes, 2018
This case presents the question whether to overrule Nevada v. Hall, 440 U.S. 410 (1979). That question requires careful attention to the legal status of sovereign immunity and to the Constitution’s effect on it, which neither Hall nor either party has ...

The exotic Galilei group and the "Peierls substitution"

open access: yes, 2000
Taking advantage of the two-parameter central extension of the planar Galilei group, we construct a non relativistic particle model in the plane. Owing to the extra structure, the coordinates do not commute.

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

Energy rule for enhancing the spin Hall effect in superposition of axisymmetric beams with cylindrical and linear polarization

open access: yesКомпьютерная оптика
We study the spin angular momentum of a superposition of two vector light beams radial symmetry, one has cylindrical polarization and another – linear. Both beams can have an arbitrary radial shape.

Numerical Computation of Material Properties of Nanocrystalline Materials Utilizing Three-Dimensional Voronoi Models

open access: yesMetals, 2019
Nanocrystalline metals have been the cause of substantial intrigue over the past two decades due to their high strength, which is highly sensitive to their microstructure. The aim of the present project is to develop a finite element two-phase model that

Thermodynamic and Tunneling Density of States of the Integer Quantum Hall Critical State

open access: yes, 2001
We examine the long wave length limit of the self-consistent Hartree-Fock approximation irreducible static density-density response function by evaluating the charge induced by an external charge.

Formation of Slip Bands and Hall-Petch Rule in Quenched Polycrystalline Pure Aluminum.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2002
In order to make clear the crystallographic interpretation of each factor composing the Hall-Petch relational equation, experiments were performed by using two kinds of polycrystalline pure aluminum, which were annealed at 573 K and followed by quenching from 773 K.
