Secretory autophagy - a new paradigm regulating synaptic plasticity. [PDF]

open access: yesAutophagy
When exposed to new experiences or changes in the environment, neurons rapidly remodel their synaptic structure and function in a process called activity-induced synaptic remodeling.

Unconventional forms of synaptic plasticity in the hippocampus and the striatum

open access: yes, 2008
Synaptic transmission occurs as a result of either a spontaneous release of presynaptic vesicles or a batch release of presynaptic vesicles driven by action potentials. The physiological consequence of synaptic transmission driven by different patterns and frequencies of presynaptic stimulation has been extensively investigated.

High-dimensional phenotyping reveals novel macrophage-like and hybrid subsets within murine splenic conventional dendritic cells. [PDF]

open access: yesPLoS ONE
Conventional dendritic cells (cDCs) are pivotal antigen-presenting cells (APCs) with critical roles in immune regulation, yet their subset classification remains ambiguous due to phenotypic overlap with macrophages and monocytes, particularly in the ...

On the applicability of multi-surface, two-surface and non-linear kinematic hardening models in multiaxial fatigue [PDF]

open access: yesFracture and Structural Integrity, 2015
In this work, a comparison between NLK and Mróz-Garud’s multi-surface formulations is presented. A unified common notation is introduced to describe the involved equations, showing that the Mróz-Garud model can be regarded as a particular case of the ...

Fatigue life assessment of a non-load carrying fillet joint considering the effects of a cyclic plasticity and weld bead shape [PDF]

open access: yesFracture and Structural Integrity, 2016
Fatigue life depends strongly on irreversible contributions that accumulate during cyclic loading and unloading of structures. However, the correct identification of the loading path in terms of uniaxial or multi-axial stress states, proportional or non ...

Concept of Using 3D Printing for Production of Concrete–Plastic Columns with Unconventional Cross-Sections [PDF]

open access: yesMaterials, 2021
A concept of concrete–plastic columns was presented in the paper. As a proof of concept, a research program was conducted. Seven different cross-sections of columns formwork were 3D printed using plastic. The cross-sections represented three types of columns’ shapes: most common, rare, and impossible to be realized using traditional formworks (based on

Cross-Generational Effects and Non-random Developmental Response to Temperature Variation in Paramecium

open access: yesFrontiers in Cell and Developmental Biology, 2020
Unicellular organisms such as ciliates are largely neglected in research on adaptive developmental plasticity, although their nuclear dualism offers ideal circumstances to study development outside an embryonic context.

Skyrmion-Magnetic Tunnel Junction Synapse With Long-Term and Short-Term Plasticity for Neuromorphic Computing [PDF]

open access: yesIEEE Transactions on Electron Devices, 2022
Magnetic skyrmion-based data storage and unconventional computing devices have gained increasing attention due to their topological protection, small size, and low driving current. However, skyrmion creation, deletion, and motion are still being studied.

Solid state processing of titanium chips by an unconventional plastic working

open access: yesJournal of Materials Research and Technology, 2021
The aim of this paper is to demonstrate how various titanium chips can be processed into solid bulk materials in the form of rods. In this work, an alternative technology for recycling chips without re-melting is presented. In order to transform chips into a new material, an unconventional plastic working method was applied that involved upsetting ...
