Uninterrupted Maximum Flow on Signalized Traffic Networks

open access: yesJournal of Advanced Transportation
This paper describes a traffic signal control strategy that allows motorists who travel at a recommended speed on suburban arterial two-way roads with a common cycle time to make every traffic signal.

GATA4‐Driven Transcription of HtrA1 Promotes Cellular Senescence in Ménière's Disease and Age‐Related Audio‐Vestibular Dysfunction

open access: yesAdvanced Science, EarlyView.
This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

On the stationary Cahn-Hilliard equation: Interior spike solutions

open access: yes, 1998
We study solutions of the stationary Cahn-Hilliard equation in a bounded smooth domain which have a spike in the interior. We show that a large class of interior points (the "nondegenerate peak" points) have the following property: there exist such ...

A Multi-Feature Adaptive Association Method for High-Frequency Radar Target Tracking

open access: yesRemote Sensing
High-frequency surface wave radar (HFSWR) with a small aperture suffers from limited azimuth resolution, which often leads to association errors and trajectory fragmentation in complex scenarios involving sea clutter and intersecting target tracks.

On Determination Method for Resolution of Secondary Electron Images in Scanning Electron Microscopy

open access: yesAdvanced Science, EarlyView.
An idealized SEM, termed Rayleigh's microscope, is constructed by Monte Carlo simulation to represent imaging conditions that just satisfy the Rayleigh criterion. Based on this physically defined model, sharpness–resolution conversion curves are established and combined with the Rose criterion, enabling automated resolution evaluation from practical ...

Reactive scattering dynamics on conically intersecting potential energy surfaces: the H + H2 exchange reaction†

open access: yes, 2001
We investigate the dynamics of a bimolecular reaction on conically intersecting potential energy surfaces. The flux operator method of calculating the state-specific total reaction probability is extended to a coupled-surface problem, both in the ...

The joys and frustrations of life as an embedded researcher: Findings from a diary study of researchers embedded within local authority public health teams in England.

open access: yesPLoS ONE
Embedded researcher interventions endeavour to facilitate culture changes in the production and use of research, so that research is contextually relevant for informing local policies and practices.

SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

Nonlinear elastic wave interactions in rock

open access: yes, 1990
We are exploiting the nonlinear elastic properties of rocks to generate low-frequency, long-wavelength elastic wave beams. The appeal of rocks for nonlinear studies arises from their numerous microcracks that compress readily under applied stress.

Investigation of Weak Shock-Shock and Shock-Expansion Intersection in the Presence of a Turbulent Boundary Layer [PDF]

open access: yes, 1987
An investigation of intersecting shock-shock and shock-expansion interactions with a turbulent boundary layer is reported. The form of these interactions is interpreted from experimental results at Mach 1.85.
