Quantitative fluorescence spectroscopy of living bacteria by optical condensation with a bubble-mimetic solid–liquid interface

AIP Advances, 2022
Microbial interactions are closely related to human health, and secreted signal molecules from bacteria determine the gene expression of bacteria following bacterial cell density and signal molecule density.

Effects of shock and turbulence properties on electron acceleration

, 2018
Using test particle simulations we study electron acceleration at collisionless shocks with a two-component model turbulent magnetic field with slab component including dissipation range. We investigate the importance of shock normal angle $\theta_{Bn}$,

Covariant Uniform Acceleration [PDF]

, 2013
We show that standard Relativistic Dynamics Equation F=dp/d\tau is only partially covariant. To achieve full Lorentz covariance, we replace the four-force F by a rank 2 antisymmetric tensor acting on the four-velocity.

Frictional collision acceleration and damage of potato peel: an experimental study

International Journal of Food Properties, 2021
To obtain the acceleration characteristics of frictional collision between potato and rod, and reveal the mechanism of potato peel damage, a frictional collision test rig was designed to conduct single factor test and peel damage threshold test.

Late-time Cosmic Dynamics from M-theory

, 2003
We consider the behaviour of the cosmological acceleration for time-dependent hyperbolic and flux compactifications of M-theory, with an exponential potential.

Future Accelerators [PDF]

AIP Conference Proceedings, 2004
I describe the future accelerator facilities that are currently foreseen for electroweak scale physics, neutrino physics, and nuclear structure. I will explore the physics justification for these machines, and suggest how the case for future accelerators can be made.

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

Population Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Indonesia Poverty Reduction Strategies: Shifting policies to promote employment in the poorest four deciles

Economics and Finance in Indonesia, 2018
This paper observes the working status and conditions of people who fall into the poorest four deciles in Indonesia. The research aims to provoke policy shifts in the drive to accelerate poverty reduction in Indonesia, taking a longer view of people ...
