Zigzag Stacks and m-Regular Linear Stacks [PDF]

Journal of Computational Biology, 2014
The contact map of a protein fold is a graph that represents the patterns of contacts in the fold. It is known that the contact map can be decomposed into stacks and queues. RNA secondary structures are special stacks in which the degree of each vertex is at most one and each arc has length at least two.

A Stacking-Based Model for Non-Invasive Detection of Coronary Heart Disease

IEEE Access, 2020
Coronary arteriongraphy (CAG) is an accurate invasive technique for the diagnosis of coronary heart disease (CHD). However, its invasive procedure is not appropriate for the detection of CHD in the annual physical examination.

Stacking-dependent electronic structure of trilayer graphene resolved by nanospot angle-resolved photoemission spectroscopy

, 2017
The crystallographic stacking order in multilayer graphene plays an important role in determining its electronic structure. In trilayer graphene, rhombohedral stacking (ABC) is particularly intriguing, exhibiting a flat band with an electric-field ...

Directional stack exchange along oriented oligothiophene stacks

Chemical Communications, 2012
Directional growth of π-basic oligothiophene stacks on solid substrates is achieved by self-organizing, surface-initiated disulfide exchange polymerization. Successful addition of co-axial π-acidic stacks by templated hydrazone exchange provides general access to multicomponent architectures of unique complexity.

Polytypes of long-period stacking structures synchronized with chemical order in a dilute Mg-Zn-Y alloy

, 2011
A series of structural polytypes formed in an Mg-1at.%Zn-2at.%Y alloy has been identified, which are reasonably viewed as long-period stacking derivatives of the hcp Mg structure with alternate AB stacking of the close-packed atomic layers.

Comparative Analysis of Hybrid Model Performance Using Stacking and Blending Techniques for Student Drop Out Prediction In MOOC

Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi)
Despite being in high demand as a lifelong learner and academic material supplement, the implementation of Massive Open Online Courses (MOOC) has problems, one of which is the dropout rate (DO) of students, which reaches 93%.

The infrared spectra of ABC-stacking tri- and tetra-layer graphenes studied by first-principles calculations

, 2010
The infrared absorption spectra of ABC-stacking tri- and tetra-layer graphenes are studied using the density functional theory. It is found that they exhibit very different characteristic peaks compared with those of AB-stacking ones, caused by the ...

Detection of Oral Beta-Lactam Antibiotics Using a Taste Sensor with Surface-Modified Lipid/Polymer Membranes

Chemosensors
In our previous study, a taste sensor modified with 3-bromo-2,6-dihydroxybenzoic acid (3-Br-2,6-DHBA) exhibited significant responses to xanthine-based substances, suggesting an allosteric detection mechanism. This study investigates the potential of the
