Published: December 2019

Significance
Circadian clocks are present in most cells of the body and act in concert to coordinate our daily physiology and behavior with the environment. Circadian misalignment between body clocks and the environment has been implicated in various pathologies. Here, we show that circadian misalignment can also occur between clocks of different peripheral tissues following exposure to hypoxia and that it stems from the differential response of core clock components to hypoxia. Intertissue circadian misalignment also occurs upon intermittent hypoxia, a model for obstructive sleep apnea (OSA). Our findings highlight the potential role of internal circadian misalignment in the pathophysiology of OSA and potentially other hypoxia-related diseases.

Authors: Yeh Wei-Chang , Lai Chyh-Ming , Tsai Meng-Hang 
Published: December 2019

Abstract
In the past, many researchers tried to find a high-quality nurse scheduling by using mathematical programming approach. However, mathematical programming approach is hard to solve the highly complex problem in the real world, because there are so many constraints. In this paper, we present Simplified Swarm Optimization (SSO), which is the stochastic optimization method proposed by Yeh [1], to solve the real world problem of Nurse Scheduling Problem (NSP). SSO designs the new update mechanism and aim to overcome the disadvantage of Particle Swarm Optimization (PSO) in discrete problem. The objective function is to maximize the fairness within all nurse’s scheduling.
Aeroacoustic noise calculation of noncompact bodies with time-domain scattered green’s function
Authors: Wang Fang , Liu Qiuhong 
Published: December 2019

Abstract
In view of the scattering effect induced by non-compact bodies, and the growing time cost of the noise calculation with high-order methods, tailored green function methods gradually become effective means to study acoustic noise of noncompact bodies. With the help of free-space green function and convective wave equation, time-domain integral method is presented to calculate scattered green function under arbitrary boundary condition. In order to verify the present method, the cylinder noise under solid wall condition is firstly calculated with stationary point source. The scattered green functions are in good agreement with Gloerfelt’s analytical solution and Takaishi’s frequency method. The pressure distribution demonstrates that the pressure appears as circle shape at low frequency but petal-like pattern at high frequency. Furthermore, point sources in parabolic moving form is chosen to study the influence of scattering effect to far field noise. Numerical results illustrate that the scattering effect is closely related to cylinder radius and the location of sound sources, large body size and sound sources adjacent closely to body surface could lead to serious scattered noise. Besides, time-domain method overcomes the limit that noise calculations have to be performed in relative coordinate system, and it can calculate scattered noise accurately and instantaneous.
Tunable structure and electronic properties of multilayer PtSe2
Authors: Hong Zhiming 
Published: December 2019

Abstract
Two dimensional (2D) materials such as graphene and transition metal dichalcogenide (TMDC) like MoS2, WTe2 have brought widespread attention as their novel 2D confined properties and applications in nano devices. Among them, the up to date multilayer PtSe2 has been reported to be high mobility, air stable and possess novel phenomenon like Dirac fermions but to date have little study as the tunable electronic properties via structural control. Here we use the first principle calculations based on density functional theory (DFT) to study the tunable structure and electronic properties of monolayer and multilayer PtSe2 by the method of strain. We find that when apply compress strain on monolayer PtSe2 at -3% or more, the photoluminescence will enhance due to a larger density of states at conductance band minimum (CBM). With the increase of layer number, the band gap become small rapidly. The band gap change from 1.3 eV for monolayer to 0.4 eV for bilayer. With three layers, the band gap becomes 0.1 eV. Begin at four layer, the PtSe2 multilayer become a negative band gap semimetal. The DOS under VBM is small for multilayers due to the large splitting between the first valence band with the second valence band. This indicate the possible low photoluminescence strength for these multilayers. Our results can pave a way for the experiment electronic and optical properties tuning in multilayer PtSe2 and possible in the similar TMDCs.

The Design of Relational Database for Multipurpose WebGIS Applications
Authors: Sutanta E , Nurnawati E K 
Published: December 2019

Abstract
GIS concepts and applications evolved from a desktop-based into web-based and mobile. These changes require a new approach in the GIS database, from spatial data separation and attribute data into a database structure approach. The problem is the database for GIS is generally designed just for specific users, objects, and territory scopes, so it can’t be applied to other applications. This paper proposed a relational database model (RDBM) design that can accommodate new changes and needs in the user‘s aspect, the objects that are processed and displayed, and the scope of the region in GIS Web Applications (WebGIS). The study was conducted in 3 stages, namely a preliminary study to obtain an overview of the concept, design, and application of RDBM on various WebGIS. Next, identified potential problems in database design for WebGIS, and finally proposed an alternative solution in the form of a new database design template that could accommodate the possibility of new changes and needs. Database design is done using MySQL. The database design process for WebGIS applications needs to anticipate the possible growth and development of different user group data, object categorization to subcategories, and the scope of the object area. Designs that meet these criteria can be done from the beginning of the design process, that is by changing two things. First, change the view of the database designer from the user view level to the conceptual view level so that the database design results can be used by several different applications. Second, expand the view of the database designer from the specific scope into a broader scope in the user aspect, object categorization, and territory coverage. Thus, the database design obtained will be in accordance with the RDBM concept.

Published: December 2019

Abstract
The millimeter accuracy deformation monitoring algorithm of the Beidou satellite navigation system is studied. Firstly, Turbo Edit method is improved to detect the cycle slip of one week. A more efficient independent double difference observation search method is proposed for BDS constellation structure. For the fixed ambiguity, a combination of decision function and sequential ambiguity is used. On this basis, BDS deformation monitoring software is developed. Finally, using the measured data of the deformation monitoring test platform, the feasibility of the application of BDS in deformation monitoring is analyzed from the aspects of constellation distribution and calculation accuracy. The results show that BDS and GPS are basically the same in the geometric distribution of satellites in the test area. The short baseline accuracy of BDS is slightly lower than that of GPS, but it can still reach the accuracy level of 1 mm in plane and 2 mm in elevation.
