Mathematical analysis of nonlocal PDEs for network generation
Authors: Böhle Tobias , Kuehn Christian
Published: December 2019

In this paper, we study a certain class of nonlocal partial differential equations (PDEs). The equations arise from a key problem in network science, i.e., network generation from local interaction rules, which result in a change of the degree distribution as time progresses. The evolution of the generating function of this degree distribution can be described by a nonlocal PDE. To address this equation we will rigorously convert it into a local first order PDE. Then, we use theory of characteristics to prove solvability and regularity of the solution. Next, we investigate the existence of steady states of the PDE. We show that this problem reduces to an implicit ODE, which we subsequently analyze. Finally, we perform numerical simulations, which show stability of the steady states.

Authors: Specht Annika Alica , Gesing Julia , Pfaeffle Roland , Koerner Antje , Kiess Wieland
Published: December 2019

Einleitung Die Geschlechtsdysphorie im Kindes- und Jugendalter (GD) zeigt sich durch eine Inkongruenz zwischen dem Geburtsgeschlecht und der gefühlten Geschlechtsidentität, welche in der Regel in der Pubertät zunimmt. Kinder und Jugendliche mit GD sind häufiger von psychischen Komorbiditäten wie Depressionen betroffen. Diese Arbeit soll einen Überblick über die von uns behandelten Patienten geben.

Methoden Es erfolgte eine Datenanalyse aus den Patientenakten von 66 Patienten, welche sich im Zeitraum von 2005 bis 2018 erstmals mit einer GD in unserer endokrinologischen Ambulanz vorstellten.

Ergebnisse Wir beobachteten einen Anstieg der Neuvorstellungen von maximal einem Patienten pro Jahr zwischen 2005 und 2011 auf zuletzt 18 Neuvorstellungen im Jahr 2018, wobei der Anteil an den insgesamt 14 339 endokrinologischen Patienten desselben Zeitraums mit 0,49% gering ist. 54 der Patienten hatten ein weibliches und 12 ein männliches Geburtsgeschlecht, damit lag das Geschlechterverhältnis bei 4,5:1. Das Durchschnittsalter bei Erstvorstellung betrug 13,6 Jahre. 49 Patienten (74%) überschritten das Pubertätsstadium P3/B3 bzw. P3/G3 nach Tanner. 48 (73%) entwickelten erste Symptome einer GD vor der Pubertät und 30 (45%) zeigten eine psychische Komorbidität. 15 Patienten (23%) berichteten über negative Reaktionen ihres sozialen Umfelds nach ihrem Outing und 17 (26%) machten Erfahrung mit Mobbing in der Schule.

Schlussfolgerung Die Patientenzahl von Kindern und Jugendlichen mit GD ist in den letzten Jahren deutlich gestiegen. Zusätzlich zu der psychischen Belastung aufgrund der GD konnten wir bei ungefähr der Hälfte der Patienten typische psychische Komorbiditäten einer GD feststellen. Außerdem berichten Kinder und Jugendliche von negativen Reaktionen bezüglich ihrer GD in der Schule und der Familie. Die hohe Variabilität des Verlaufs und der Komorbiditäten stellt die zentrale Herausforderung in der Therapie dar.
Men Are from Mars, Idiopathic Intracranial Hypertension Is from Venous: The Role of Venous Sinus Stenosis and Stenting in Idiopathic Intracranial Hypertension
Authors: Dinkin Marc , Oliveira Cristiano
Published: December 2019

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a disease primarily affecting obese women of child-bearing age, typically presenting with positional headaches, diplopia from abducens nerve palsies, pulse-synchronous tinnitus, and visual disturbances related to papilledema, including transient visual obscurations, blurry vision, and visual field defects. Controversy remains regarding the pathophysiology of IIH. Elevated intracranial pressure in IIH is thought to be the result of a dysregulation of cerebrospinal fluid (CSF) dynamics, through excessive secretion, reduced drainage, or both. Passive CSF drainage through the arachnoid granulations depends on a pressure gradient between the subarachnoid space and the cerebral venous system, such that elevations in cerebral venous pressure lead to impaired CSF drainage. Dural venous sinus stenosis (DVSS) at the junction of the transverse and sigmoid sinuses, leading to local venous hypertension and a secondary reduction in CSF drainage through the arachnoid granulations, is increasingly recognized as an important component of the pathophysiology of IIH. A growing number of studies have demonstrated a role for stenting of DVSS as an alternative to CSF shunting and optic nerve sheath fenestration in medically refractory IIH patients with vision loss or debilitating symptoms.

Nitrogen-vacancy (NV) centers feature outstanding properties such as a spin coherence time of up to 1 s as well as a level structure offering the possibility to initialize, coherently manipulate, and optically read-out the spin degree of freedom of the ground state. However, only about 3% of their photon emission is channeled into the zero phonon line (ZPL), limiting both the rate of indistinguishable single photons and the signal-to-noise ratio (SNR) of coherent spin-photon interfaces. We here report on the enhancement of the SNR of the optical spin read-out achieved by tuning the mode of a two-dimensional photonic crystal (PhC) cavity into resonance with the NV-ZPL. PhC cavities are fabricated by focused ion beam milling in thin reactive ion etched ultrapure single crystal diamond membranes featuring modes with Q-factors of up to 8250 at mode volumes below one cubic wavelength. NV centers are produced in the cavities in a controlled fashion by a high resolution atomic force microscope implantation technique. On cavity resonance, we observe a lifetime shortening from 9.0 ns to 8.0 ns as well as an enhancement of the ZPL emission by almost one order of magnitude. Although on resonance the collection efficiency of ZPL photons and the spin-dependent fluorescence contrast are reduced, the SNR of the optical spin read-out is almost tripled for the cavity-coupled NV centers.

Published: December 2019

Environmental contextAlthough arsenic-containing lipids are widespread in marine environments, their origin remains unknown. We show that the arsenolipids in a filter-feeding bivalve mollusc closely match those found in marine food sources, including unicellular algae and bacteria. The results demonstrate the role of lower trophic levels in determining the forms of arsenic found in higher organisms.
AbstractArsenic-containing lipids, arsenolipids, are widely found among marine organisms, but their origin and possible biochemical roles remain unknown This work describes the diversity and abundance of arsenolipids in the digestive gland and mantle of nine specimens of the Mediterranean mussel, Mytilus galloprovincialis. By using high performance liquid chromatography (HPLC) coupled to both elemental and high-resolution molecular mass spectrometry, we identified 36 arsenolipids including arsenic derivatives of fatty acids, hydrocarbons, sugar-phospholipids and sugar-phytol; 21 of these arsenolipids were identified for the first time and included a new group comprising ether-phospholipids. The arsenic compounds in the mussels show distinct profiles depending on the tissue type, which provide insight into the arsenolipid origin. The results suggest that the presence of some arsenolipids in the mussels is from direct uptake of the compounds, presumably from food, rather than biogenesis within the mussels.

Brown planthopper (BPH) is one of the most destructive insects affecting rice (
Oryza sativa
L.) production. Phenylalanine ammonia-lyase (PAL) is a key enzyme involved in plant defense against pathogens, but the role of PAL in insect resistance is still poorly understood. Here we show that expression of the majority of
PALs
in rice is significantly induced by BPH feeding. Knockdown of Os
PALs
significantly reduces BPH resistance, whereas overexpression of
OsPAL8
in a susceptible rice cultivar significantly enhances its BPH resistance. We found that
OsPALs
mediate resistance to BPH by regulating the biosynthesis and accumulation of salicylic acid and lignin. Furthermore, we show that expression of
OsPAL6
and
OsPAL8
in response to BPH attack is directly up-regulated by OsMYB30, an R2R3 MYB transcription factor. Taken together, our results demonstrate that the phenylpropanoid pathway plays an important role in BPH resistance response, and provide valuable targets for genetic improvement of BPH resistance in rice.

The fundamental importance of the 26S proteasome in health and disease suggests that its function must be finely controlled, and yet our knowledge about proteasome regulation remains limited. Posttranslational modifications, especially phosphorylation, of proteasome subunits have been shown to impact proteasome function through different mechanisms, although the vast majority of proteasome phosphorylation events have not been studied. Here, we have characterized 1 of the most frequently detected proteasome phosphosites, namely Ser361 of Rpn1, a base subunit of the 19S regulatory particle. Using a variety of approaches including CRISPR/Cas9-mediated gene editing and quantitative mass spectrometry, we found that loss of Rpn1-S361 phosphorylation reduces proteasome activity, impairs cell proliferation, and causes oxidative stress as well as mitochondrial dysfunction. A screen of the human kinome identified several kinases including PIM1/2/3 that catalyze S361 phosphorylation, while its level is reversibly controlled by the proteasome-resident phosphatase, UBLCP1. Mechanistically, Rpn1-S361 phosphorylation is required for proper assembly of the 26S proteasome, and we have utilized a genetic code expansion system to directly demonstrate that S361-phosphorylated Rpn1 more readily forms a precursor complex with Rpt2, 1 of the first steps of 19S base assembly. These findings have revealed a prevalent and biologically important mechanism governing proteasome formation and function.

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.
Nurse scheduling problem using Simplified Swarm Optimization
Authors: Yeh Wei-Chang , Lai Chyh-Ming , Tsai Meng-Hang
Published: December 2019

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

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

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

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.

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.

Authors: Zheng Xiaodong , Hao Jianguo
Published: December 2019

Based on the incremental dynamic analysis method, a new index (the ratio of plastic energy consumption to total deformation energy) for evaluating the seismic performance of earthquake-resistant dams is proposed. Suggestions for three levels of earthquake damage and failure classification in two extreme states of gravity dam seismic performance evaluation are given. The IDA analysis of the concrete gravity dam was carried out by nonlinear numerical analysis model. Based on this, the quantile analysis and fragility analysis were carried out. The results show that ①the peak ground acceleration PGA of each limit state in the IDA curve of the quantile analysis is larger than the peak ground acceleration of the designed earthquake, which satisfies the level of functional support and safety assurance of the gravity dam. ②Under the fragility analysis, the probability of 65.92% is in the normal use stage of the 1.5 times design earthquake, and 100% can guarantee safety. The results show that the gravity dam has good seismic performance. The results of this study provide new ideas for the seismic performance design and safety risk assessment of gravity dams.

Published: December 2019

The current rural construction presents a new situation in which multiple perspectives are involved. As one of the important cut-in points for intervention, the academic community has begun to explore and practice the rural construction model based on “geological culture”. Starting from the ontology of rural geological environment resources, the four-dimensional attributes including geological relics, agricultural geological resources, human landscapes and natural landscapes are concerned, and the evaluation method of geological culture village based on analytic hierarchy process (AHP) is discussed. Through the comprehensive evaluation index system of geological culture villages with two basic connotations of environmental resources, development conditions and development benefits, seven types of geological relics, agricultural geological resources, human landscape, natural landscape, human settlement environment, public service and development benefit are proposed. The second-level index consists of a total of 16 third-level indicators of the comprehensive evaluation system of geological culture villages. The article aims to lay a foundation for the planning and design of geological and cultural villages through the construction of the evaluation system and promote the healthy and sustainable development of the geological culture villages.

A Ce/TiO2/g-C3N4 composite material was prepared by sol-gel method using g-C3N4 as support and Ce(NH4)2(NO3)6 as dopant. The structural and morphological characterization of the samples was detected by TEM, XRD, FTIR, UV-Vis. RhB was selected as the target pollutant, the photocatalytic and renewable properties of the samples driven by visible light were evaluated. The results showed that Ce/TiO2/g-C3N4 had excellent heterojunction structure. The ternary components cooperate with each other to show excellent photocatalytic performance for RhB solution with molar concentration of 0.5×10−5mol·L−1 under the condition of dosage of 20.0mg, pH 5.0 and visible light-driven 180min. The degradation rate of RhB was 99.3% better than that of g-C3N4, TiO2 and Ce/TiO2. Cyclic degradation experiments indicated that the Ce/TiO2/g-C3N4 had high photocatalysis stability and reusability. Active group capture experiments revealed that ·O2
- was the main active species in the photocatalytic degradation of RhB over Ce/TiO2/g-C3N4, and the corresponding contribution rate of ·O2
- was 84.1%.
