Vortex lines or sheets - what is formed in dynamic drives?

open access: yes, 2001
In isotropic macroscopic quantum systems vortex lines can be formed while in anisotropic systems also vortex sheets are possible. Based on measurements of superfluid 3He-A, we present the principles which select between these two competing forms of ...

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Partial henselizations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
We define and note some properties of kH-pairs (k Henselian pairs), kN-pairs, and kN′-pairs. It is shown that the 2-Henselization and the 3- Henselization of a pair exist.

Synchronization of flexible sheets

open access: yes, 2011
When swimming in close proximity, some microorganisms such as spermatozoa synchronize their flagella. Previous work on swimming sheets showed that such synchronization requires a geometrical asymmetry in the flagellar waveforms.

Chemical Self Assembly of Graphene Sheets [PDF]

open access: yes, 2009
Chemically derived graphene sheets were found to self-assemble onto patterned gold structures via electrostatic interactions between noncovalent functional groups on GS and gold. This afforded regular arrays of single graphene sheets on large substrates,

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Peripheral nerve injury reduces the excitation-inhibition balance of basolateral amygdala inputs to prelimbic pyramidal neurons projecting to the periaqueductal gray

open access: yesMolecular Brain, 2020
Cellular and synaptic mechanisms underlying how chronic pain induces maladaptive alterations to local circuits in the medial prefrontal cortex (mPFC), while emerging, remain unresolved.

TRADITIONAL USES OF INPUT-OUTPUT MODELS IN WATERSHED PROGRAMS PLANNED UNDER PRINCIPLES AND GUIDELINES [PDF]

open access: yes
This paper outlines the traditional uses of input-output (I/O) modeling in watershed programs planned under federal "Principles and Guidelines." Generally, the national economic development costs and benefits are analyzed, and the I/O model is used to ...
