Numerical Investigation on Stability of Lanxi’s Ancient City Wall during a Major Flood Propagation Process

Buildings
Major flood propagation processes often cause instability and damage to the ancient waterfront city walls. To quantitatively reveal the impact of major floods on the stability of ancient city walls, this paper takes Lanxi’s ancient city wall as a study ...

Intact Stability Analysis of Crew Boat with Variation of Deadrise Angle [PDF]

, 2016
¾ As a supporter of offshore supply logistics operations, crew boat moving in high speed needs the hull design that is able to reduce the resistance but the stability is still good.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Global stability analysis and stabilization of power amplifiers [PDF]

2008 Microwaves, Radar and Remote Sensing Symposium, 2008
Power amplifiers often exhibit undesired behavior from certain input power value which cannot be predicted with a small-signal stability analysis. Among the commonly observed undesired phenomena are spurious oscillations, frequency divisions, hysteresis or chaos.

Constrained basin stability for studying transient phenomena in dynamical systems

, 2016
Transient dynamics are of large interest in many areas of science. Here, a generalization of basin stability (BS) is presented: constrained basin stability (CBS) that is sensitive to various different types of transients arising from finite size ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Optimal allosteric stabilization sites using contact stabilization analysis [PDF]

Journal of Computational Chemistry, 2016
Proteins can be destabilized by a number of environmental factors such as temperature, pH, and mutation. The ability to subsequently restore function under these conditions by adding small molecule stabilizers, or by introducing disulfide bonds, would be a very powerful tool, but the physical principles that drive this stabilization are not well ...

Z-stability in Constructive Analysis

, 2016
We introduce Z-stability, a notion capturing the intuition that if a function f maps a metric space into a normed space and if the norm of f(x) is small, then x is close to a zero of f.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Radial stability analysis of the continuous pressure gravastar

, 2012
Radial stability of the continuous pressure gravastar is studied using the conventional Chandrasekhar method. The equation of state for the static gravastar solutions is derived and Einstein equations for small perturbations around the equilibrium are ...
