Are "Hierarchical" Visual Representations Hierarchical?

open access: yesCoRR, 2023
Learned visual representations often capture large amounts of semantic information for accurate downstream applications. Human understanding of the world is fundamentally grounded in hierarchy. To mimic this and further improve representation capabilities, the community has explored "hierarchical" visual representations that aim at modeling the ...

Research Progress on the Synthesis of Nanosized and Hierarchical Beta Zeolites

open access: yesInorganics, 2023
Beta zeolite, a crystal material with a three-dimensional twelve-ring cross-channel structure, has many advantages, such as high Brønsted acid concentration, high Si/Al ratio, thermal/hydrothermal stability, and large surface area.

Bioinspired Tough and Strong Fibers with Hierarchical Core–Shell Structure

open access: yesAdvanced Materials Interfaces, 2023
Strong and tough bio‐based fibers are attractive for both fundamental research and practical applications. In this work, strong and tough hierarchical core–shell fibers with cellulose nanofibrils (CNFs) in the core and regenerated silk fibroins (RSFs) in

Finding Hierarchical Structures of Disordered Systems: An Application for Market Basket Analysis

open access: yesIEEE Access, 2021
Complex systems can be characterized by their level of order or disorder. An ordered system is related to the presence of system properties that are correlated with each other.

Macroscopic helical chirality and self-motion of hierarchical self-assemblies induced by enantiomeric small molecules

open access: yesNature Communications, 2018
Chirality transfer by chemical self-assembly has been studied intensively for years but chirality transfers along the same path remains elusive. Here the authors use a multiscale chemo-mechanical model to elucidate the mechanism underlying the chirality ...

Serbian adaptation of the positive and negative affect schedule (PANAS): Its facets and second-order structure [PDF]

open access: yesPsihologija, 2014
Although the PANAS is widely used in affect research there are some controversies regarding its structure. Two related studies were reported providing evidence that a Serbian adaptation of the PANAS represents a valid and reliable measure of ...

Uncovering the different scales in deer–forest interactions

open access: yesEcology and Evolution, 2021
Deer are regarded to be a keystone species as they play a crucial role in the way an ecosystem functions. Most deer–forest interaction studies apply a single scale — process of analyzing ecological interactions by only taking into account one dependent ...

On the complexity of hierarchical problem solving

open access: yes, 2005
Competent Genetic Algorithms can efficiently address problems in which the linkage between variables is limited to a small order k. Problems with higher order dependencies can only be addressed efficiently if further problem properties exist that can be ...
