Parallel olfactory processing in the honey bee brain: odor learning and generalization under selective lesion of a projection neuron tract

Frontiers in Integrative Neuroscience, 2016
The function of parallel neural processing is a fundamental problem in Neuroscience, as it is found across sensory modalities and evolutionary lineages, from insects to humans.

Application of Biological Learning Theories to Mobile Robot Avoidance and Approach Behaviors [PDF]

, 1998
We present a neural network that learns to control approach and avoidance behaviors in a mobile robot using the mechanisms of classical and operant conditioning.

Second order optimality conditions for differentiable multiobjective problems [PDF]

RAIRO - Operations Research, 2000
Summary: A secood order optimality condition for multiobjective optimization with a set constraints is developed; this condition is expressed as the impossibility of nonhomogeneous linear systems. When the constraint is given in terms of inequalities and equalities, it can be turned into a John type multipliers rule, using a nonhomogeneous Motzkin ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Bifurcation Theorems via Second-Order Optimality Conditions

Journal of Mathematical Analysis and Applications, 2001
The authors prove new bifurcation existence theorems based on the theory of second-order optimality conditions for abnormal constrained optimization problems [the first author, Optimality conditions. Abnormal and degenerate problems. Dordrecht: Kluwer Academic Publishers (2000; Zbl 0987.49001)]. Remarks: In the list of references the following articles

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

FEBS 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.

Second order systems with nonlinear boundary conditions [PDF]

Proceedings of the American Mathematical Society, 1977
Some existence theorems are established for nonlinear second order systems with nonlinear two point boundary conditions. The system is assumed to satisfy certain differential inequality conditions at the boundary of a region.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Bumblebee social learning outcomes correlate with their flower-facing behaviour

Animal Cognition
Previous studies suggest that social learning in bumblebees can occur through second-order conditioning, with conspecifics functioning as first-order reinforcers.

Factorial Experiments of Soil Conditioning for Earth Pressure Balance Shield Tunnelling in Water-Rich Gravel Sand and Conditioning Effects’ Prediction Based on Particle Swarm Optimization–Relevance Vector Machine Algorithm

Buildings
The high permeability of gravel sand increases the risk of water spewing from the screw conveyor during earth pressure balance (EPB) shield tunnelling.
