Underwater image matching by incorporating structural constraints

open access: yesInternational Journal of Advanced Robotic Systems, 2017
Underwater robot plays an important role in underwater perception and manipulation tasks. Vision information processing is essential for the intelligent perception of an underwater robot, in which image matching is a fundamental topic.

Stability constraints on large-scale structural brain networks

open access: yesFrontiers in Computational Neuroscience, 2013
Stability is an important dynamical property of complex systems and underpins a broad range of coherent self-organized behaviour. Based on evidence that some neurological disorders correspond to linear instabilities,we hypothesize that stability ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Model selection in regression under structural constraints

open access: yes, 2013
The paper considers model selection in regression under the additional structural constraints on admissible models where the number of potential predictors might be even larger than the available sample size.

A control approach to scheduling flexibly configurable jobs with dynamic structural-logical constraints

open access: yesIISE Transactions, 2020
We study the problem of scheduling in manufacturing environments which are dynamically reconfigurable for supporting highly flexible individual operation compositions of the jobs.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Constraints on extended neutral gauge structures [PDF]

open access: yesPhysics Letters B, 1999
Indirect precision data are used to constrain the masses of possible extra Z^prime bosons and their mixings with the ordinary Z. We study a variety of Z^prime bosons as they appear in E_6 and left-right unification models, the sequential Z boson, and the example of an additional U(1) in a concrete model from heterotic string theory.
