Spacetime in the brain: rapid brain network reorganization in visual processing and recovery

Scientific Reports, 2021
Functional connectivity networks (FCN) are the physiological basis of brain synchronization to integrating neural activity. They are not rigid but can reorganize under pathological conditions or during mental or behavioral states. However, because mental

The Spin Distribution of Millisecond X-ray Pulsars

, 2008
The spin frequency distribution of accreting millisecond X-ray pulsars cuts off sharply above 730 Hz, well below the breakup spin rate for most neutron star equations of state. I review several different ideas for explaining this cutoff.

An ultraluminous nascent millisecond pulsar [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2015
Abstract If the ultraluminous source (ULX) M82 X-2 sustains its measured spin-up value of $\dot{\nu }= 10^{-10}\,{\rm s^{-2}}$, it will become a millisecond pulsar in less than 105 yr. The observed (isotropic) luminosity of 1040 erg s−1 also supports the notion that the neutron star will spin up to a millisecond period upon accreting ...

Can eccentric binary millisecond pulsars form by accretion induced collapse of white dwarfs?

, 2010
Binary radio pulsars are generally believed to have been spun up to millisecond periods (i.e. recycling) via mass accretion from their donor stars, and they are the descendants of neutron star low-mass X-ray binaries.

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Giant Pulses in Millisecond Pulsars [PDF]

Symposium - International Astronomical Union, 2004
Giant pulses (GPs), occasional individual pulses with an intensity 100 times the average intensity, have been detected in four pulsars to date. Their origin is not well understood, but studies suggest a connection between the strength of magnetic field at the light cylinder Blc and the existence of GPs. Here, we report on detection of significant Large

Probing the millisecond pulsar origin of the γ-ray excess in the Galactic centre with LISA

Astronomy & Astrophysics
The gigaelectronvolt γ-ray excess observed towards the Galactic centre remains unexplained. While dark matter annihilation has long been considered a leading explanation, an alternative scenario involving a large population of millisecond pulsars remains

Low‐Thermal‐Budget Doping of 2D Materials in Ambient Air Exemplified by Synthesis of Boron‐Doped Reduced Graphene Oxide

Advanced Science, 2020
Graphene oxide (GO) doping and reduction allow for physicochemical property modification to suit practical application needs. Herein, the challenge of simultaneous low‐thermal‐budget heteroatom doping of GO and its reduction in ambient air is addressed ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.
