Analysis of the Effects of Sugar Modifications on RNA Chemical Ligation Reactions. [PDF]

Chembiochem
The effect of substitutions at the 2′ position of the nucleotides at the ligation site on phosphoramidate‐type chemical ligation reaction efficiency is examined. The efficiency varies depending on the substituents, with the combination of a fluorine group on 5′NRNA and an O‐methyl group on RNA3′P showing the highest efficiency. Chemical ligation of RNA

Modeling of mechanosensitive remodeling processes in collagen fibers

Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 3, November 2023., 2023
Abstract A large number of biochemical processes such as enzymatic collagen degradation are involved in the remodeling of biological soft tissue constituents. Experiments have found that moderate strain may stabilize fibrillar collagen to enzymatic degradation.

Evaluation of postprandial total triglycerides within the TIGG model for characterizing postprandial response of glucose, insulin, and GLP‐1

CPT: Pharmacometrics &Systems Pharmacology, Volume 12, Issue 10, Page 1529-1540, October 2023., 2023
Abstract The TIGG model is the first model to integrate glucose and insulin regulation, incretin effect, and triglyceride (TG) response in the lipoprotein subclasses of chylomicrons and VLDL‐V6. This model described the response following a high‐fat meal in individuals who are lean, obese, and very obese and provided insights into the possible ...

Integrated Logic for Dielectric Elastomers: Replicating the Reflex of the Venus Flytrap

Advanced Materials Technologies, Volume 8, Issue 12, June 23, 2023., 2023
Dielectric elastomers (DEs) are a class of electroactive polymers that usually need external circuitry to control their operation. This work demonstrates the autonomous control of a DE gripper with a circuit made of the same polymer. The final device, also provided with sensors, mimics the Venus flytrap plant, autonomously gripping objects that touch ...

Bifurcation of fiber reinforced inflated membranes with different natural configurations of the constituents

Proceedings in Applied Mathematics and Mechanics, Volume 22, Issue 1, March 2023., 2023
Abstract This article studies the inflation and bulging of fiber‐reinforced hyperelastic membranes. A neo‐Hookean model describes the mechanical behavior of the ground substance, and a relatively standard reinforcing model describes the mechanical behavior of fibers.

SDNet: Image‐based sonar detection network for multi‐scale objects

IET Image Processing, Volume 17, Issue 4, Page 1208-1223, 27 March 2023., 2023
This paper proposes a real‐time object detection network SDNet for sonar images. The experimental results show that SDNet can effectively balance the detection accuracy and efficiency in sonar images. Abstract Autonomous Underwater Vehicle (AUV) carrying sonar for object detection has become one of the main ways of ocean exploration.

Exploring the role of the long short‐term memory model in improving multi‐step ahead reservoir inflow forecasting

Journal of Flood Risk Management, Volume 16, Issue 1, March 2023., 2023
Abstract Daily inflow forecasting is of vital importance in reservoir economic operation. In the context of hydrometeorological forecasting, the effectiveness of the data‐driven models has been demonstrated as bias correctors for physically‐based models or direct forecasting models.

The Maya Are a People of Movement: Reconstructing Shifts in Maya Mobility From Oxygen Isotopes Across Three Millenia at Santa Rita Corozal (Chactemal), Northern Belize. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Decades of archaeological and bioarchaeological research have demonstrated that ancient Maya cities underwent dynamic changes over time, including shifts in sociopolitical organization as well as their cultural and economic ties to other areas of Mesoamerica.

Magnon-Like Dispersion Relation from M-Theory [PDF]

, 2006
We investigate classical rotating membranes in two different backgrounds. First, we obtain membrane solution in $AdS_4\times S^7$ background, analogous to the solution obtained by Hofman and Maldacena in the case of string theory.

Simultaneous Bayesian Sparse Approximation with Structured Sparse Models [PDF]

, 2016
Sparse approximation is key to many signal processing, image processing and machine learning applications. If multiple signals maintain some degree of dependency, for example the support sets are statistically related, then it will generally be ...
