Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Using Brownian dynamics, we study the basic physical properties of a new model for two-dimensional semiflexible biopolymers at finite temperature. The new model adopts a new nearest neighbor interaction. The new potential has stronger constraint on the distances between nearest monomers, therefore may provide a better approximation to the biopolymers with covalent-bond between the nearest-neighbor monomers.
This work focuses on the testing and modifying the new program, and has not yet considered the influences of the external force and the intrinsic curvatures. By monitoring some quantities in simulation, we find the proper simulation parameters (the time step, total simulation time and number of samples) in the temperature range (0.01, 0.2) for our system (a chain of monomers). We find that the mean x-coordinate of the end particle, the mean end-to-end distance and the mean radius of gyration decrease with increasing temperature. These results agree with the well known fact that the entropy dominates the behavior of the biopolymers at normal temperature, and provide evidences for the correctness of the program. We also find that the radius of gyration of the chain has abnormal behavior, but the origin of the abnormal behavior is still unclear so requires a further investigation. Moreover, our results indicate that there is linear relation between the mean end-to-end distance and the mean radius of gyration, and the proportional constant increases slowly with increasing temperature.
