Background Previous neuroimaging studies demonstrated that individuals with high myopia are associated with abnormalities in anatomy of the brain. Purpose The purpose of this study was to explore alterations in the intrinsic brain activity by studying the amplitude of low-frequency fluctuations. Material and Methods A total of 64 myopia individuals (41 with high myopia with a refractive error <–600 diopter [D], 23 with low/moderate myopia with a refractive error between –100 and –600 D, and similarly 59 healthy controls with emmetropia closely matched for age) were recruited. The amplitude of low-frequency fluctuations method was conducted to investigate the difference of intrinsic brain activity across three groups. Results Compared with the healthy controls, individuals with low/moderate myopia showed significantly decreased amplitude of low-frequency fluctuation values in the bilateral rectal gyrus, right cerebellum anterior lobe/calcarine, and bilateral thalamus and showed significantly increased amplitude of low-frequency fluctuation values in left white matter (optic radiation), right prefrontal cortex, and left primary motor cortex (M1)/primary somatosensory cortex (S1). In addition, individuals with high myopia showed significantly decreased amplitude of low-frequency fluctuation values in the right cerebellum anterior lobe/calcarine/bilateral parahippocampal gyrus, bilateral posterior cingulate cortex, and bilateral middle cingulate cortex and significantly increased amplitude of low-frequency fluctuation values in left white matter (optic radiation), bilateral frontal parietal cortex, and left M1/S1. Moreover, we found that the amplitude of low-frequency fluctuation values of the different brain areas was closely related to the clinical features in the high myopia group. Conclusion Our results demonstrated that individuals with low/moderate myopia and high myopia had abnormal intrinsic brain activities in various brain regions related to the limbic system, default mode network, and thalamo-occipital pathway.

Objective The aim of this study was to evaluate the changes in CD8+CD28–/CD8+CD28+ T-cell subset balance and in the CD8+CD28– Treg cell number and function in patients with systemic lupus erythematosus (SLE). Methods Cell isolation and flow cytometry analysis were employed to investigate the T-cell subsets. Results It was found that in high-activity SLE patients, the CD8+CD28+ T-cell subset was reduced, which was inversely correlated with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), and that the CD8+CD28–/CD8+CD28+ ratio was elevated, which was positively correlated with SLEDAI and with renal damage and inversely correlated with serum complement level, whereas the CD8+CD28– T-cell subset was increased only in inactive patients. It was also found that apoptosis of CD8+ T cells increased, and Fas, Fas ligand (FasL) and interleukin (IL)-6 expression were high, whereas cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4) expression was low by the CD8+CD28+ T cell subset in active SLE patients; apoptosis was positively correlated with SLEDAI and with the expression of Fas and FasL by the CD8+CD28+ T-cell subset in active SLE patients. IL-6 and CTLA-4 expression were found to be low by the CD8+CD28– T cell subset in active SLE patients. Conclusion These data suggest that high expression of Fas, FasL and IL-6 and low expression of CTLA-4 by the CD8+CD28+ T-cell subset promotes the activation-induced cell death of the CD8+CD28+ T-cell subset, resulting in an imbalance of CD8+CD28–/CD8+CD28+ T cells in active SLE patients, which represents an important feature in the immunological pathogenesis of SLE. The CD8+CD28– T-cell subset may play some role in inactive SLE.

Strength based design is commonly used in the design of resisting earthquake building. It is analyzed by linear elastic method so that it can’t describe the seismic behaviour of the structures. For that reason, the design of structure needs to consider performance based design. Irregularity of structure play important role for the results of Structure Performance. This paper uses five models of 20 storey reinforced concrete building with same height(76 m) and areas(750m2) with different plan configurations: rectangular, T, L, U, and H-shaped. Non linear time history method is used to investigate the seismic behaviour of the structures, using finite model with ETABS2016. Dimension of structures are column (600 x1000 mm), shear wall (400mm), couple-beam (400x900 mm), slab (140mm). Recorded accelorogram used in this paper are Altadena, Array, Corralit, LACC, and Yermo because it has almost same earthquake mechanism, magnitude, and epicentrum distance, so that they are used as an artificial accelorogram that is synthesized using Wavelet Function according to SNI 1726-2012.Result shows that the story drift and plastic hinges for collapse prevention (CP) are: rectangular (story drift is 0.59% and amount of CP hinges are 8), H-shaped (1.58%/23), L-shaped (2.41%/30), U-shaped (4.59%/35), T-shaped (5.8%/58).

SNI 1726:2012 states that surface spectral accelerations SMS (0.2 second) and SM1 (1 second) can be calculated by multiplying site factors Fa (0.2 second) and Fv (1 second) with spectral accelerations SS (0.2 second) dan S1 (1 second). All site factors used by SNI 1726:2012 are adopted from ASCE/SEI 7-10. In 2013 Stewart and Seyhan proposed new and different site factors compared to ASCE/SEI 7-10. These site factors are then used for developing ASCE/SEI 7-16 with minor improvement for site class SE (soft soil). ASCE/SEI 7-16 states that the site factors for site class SE with SS greater than 1g or S1 greater than 0.2g, shall be calculated using Site Specific Analysis (SSA). The SSA method used for calculating site factor is difficult for ASCE/SEI 7-16 to be implemented in Indonesia. This paper describes the result of SMS and SM1 study at five cities (Jakarta, Bandung, Semarang, Yogyakarta and Surabaya) for site class SC, SD and SE using site factors proposed by Stewart and Seyhan and site factor SNI 1726:2012. The SMS and SM1 at five cities calculated using site factors proposed by Stewart and Seyhan are ±15% differences compared to SMS and SM1 calculated usingSNI 1726:2012 site factors.

Some hemivariational inequalities in the Euclidean space
Authors: Bisci Giovanni Molica , Repovš Dušan 
Published: August 2019

AbstractThe purpose of this paper is to study the existence of weak solutions for some classes of hemivariational problems in the Euclidean space ℝd(d≥ 3). These hemivariational inequalities have a variational structure and, thanks to this, we are able to find a non-trivial weak solution for them by using variational methods and a non-smooth version of the Palais principle of symmetric criticality for locally Lipschitz continuous functionals, due to Krawcewicz and Marzantowicz. The main tools in our approach are based on appropriate theoretical arguments on suitable subgroups of the orthogonal groupO(d) and their actions on the Sobolev spaceH1(ℝd). Moreover, under an additional hypotheses on the dimensiondand in the presence of symmetry on the nonlinear datum, the existence of multiple pairs of sign-changing solutions with different symmetries structure has been proved. In connection to classical Schrödinger equations a concrete and meaningful example of an application is presented.

Published: August 2019

Abstract
Methods for fabricating micro- and nanoscale three-dimensional (3D) structures such as electron-beam lithography (EBL) attracted attention in various fields. In EBL, an acceleration-voltage modulation method can be used to control the developing depth of the structure. In this study, we fabricated a rose petal structure using acceleration-voltage modulation. Using a rose petal mold, plastic- and silver-duplicated rose petals were prepared using nano-imprint lithography (NIL). We demonstrated that various complex 3D structures and materials can be duplicated using NIL by applying an acceleration-voltage modulation method.
Die rechtlichen Hintergründe der Neuregelung der Sonntagsöffnung öffentlicher Bibliotheken in Nordrhein-Westfalen
Authors: Steinhauer Eric W. 
Published: August 2019

Zusammenfassung
Will man eine Sonntagsöffnung öffentlicher Bibliotheken ermöglichen, so ist dies ohne gesetzgeberische Maßnahmen nicht möglich. Soll neben der bloßen Öffnung des Gebäudes auch Bibliothekspersonal am Sonntag beschäftigt werden, kann auf eine arbeitszeitrechtliche Regelung nicht verzichtet werden. Solange der Bund hier keine Neubestimmung der Ausnahmen in § 10 ArbZG vornimmt, bleibt für die Länder nur der Weg über eine Regelung in eigenen Bedarfsgewerbeverordnungen. Nordrhein-Westfalen wird diesen Weg nach Hessen als zweites Bundesland beschreiten. Im Gegensatz zu Hessen wurde die geplante Regelung aber sorgfältiger ausgearbeitet und begründet. Ob dies einen Rechtsstreit wie im Fall Hessens verhindern wird, bleibt abzuwarten. Nicht unrealistisch ist allerdings die Überlegung, dass die Neuregelung in Nordrhein-Westfalen nach Jahren des Stillstandes endlich auch auf der Bundesebene zu einer überfälligen Novelle des Arbeitszeitgesetzes führt.

Die Sonntagsöffnung für Öffentliche Bibliotheken in Nordrhein-Westfalen aus der Sicht des Borromäusvereins
Authors: Schröer Guido 
Published: August 2019

Zusammenfassung
Der Schutz des arbeitsfreien Sonntags ist ein hohes Gut. Durch mehr und mehr verkaufsoffene Sonntage wird dieser Schutz aufgeweicht. Bibliotheken stehen aber nicht für Kommerz, es geht nicht ums Einkaufen, es geht um ein wichtiges kulturelles Angebot. Dieses soll auch am Sonntag zugänglich sein. Die Art und Weise ist dabei näher zu bestimmen, nicht alle bibliothekarischen Aufgaben sollen am Sonntag erledigt werden. Bibliotheksmitarbeiter*innen sollen nicht unnötig belastet werden. Ganz ohne Sonntagsdienst wird es aber auf absehbare Zeit auch nicht gehen.

Die Bibliothek gehört den Bürger*innen - auch und vor allem am Sonntag!
Authors: Leik Tim 
Published: August 2019

Zusammenfassung
Seit dem 24. September 2017 ist die Zentral- und Landesbibliothek Berlin, Standort Amerika-Gedenkbibliothek, sonntags geöffnet. Jeden Sonntag finden in den Räumen der Amerika-Gedenkbibliothek zahlreiche Veranstaltungen für Kinder und Erwachsene statt. Die Reaktion der Besucher*innen auf die erweiterten Öffnungszeiten könnte kaum deutlicher ausfallen: Im Durchschnitt kommen sonntags rund 2.000 Besucher*innen in die Amerika-Gedenkbibliothek. Mit der Aktion Offener Sonntag verfolgt die Zentral- und Landesbibliothek Berlin zweierlei: erstens eine Änderung des Arbeitszeitgesetzes und zweitens die Bibliothek als Experimentierraum zu betrachten, um den Ort unter anderem zu einer partizipativen Plattform für die Berliner Stadtgesellschaft (weiter) zu entwickeln.

In the case of Raviart–Thomas finite elements of arbitrary polynomial degree, the resulting error estimator constitutes a guaranteed upper bound for the error and is shown to be local efficient.
Our reconstruction is performed locally on a set of vertex patches.
Inhibitory effect of activin A on IL-9 production by mouse NK cells through Smad3 signaling

Published: August 2019

Abstract
Interleukin-9 (IL-9) is a cytokine secreted by T-helper (Th)9 cells, and activin A can enhance Th9 cell differentiation. However, whether activin A affects IL-9 production by natural killer (NK) cells remains unclear. Herein, we found that not only Th cells, but also CD3−CD49b+NKp46+ NK cells of Balb/c mice produced IL-9. Although activin A promoted IL-9 expression in CD4+ Th cells, it inhibited IL-9 production by CD49b+NKp46+ NK cells in mice. Furthermore, the enzyme-linked immunosorbent assay (ELISA) results showed that mouse NK cells could secrete mature IL-9 protein, and activin A inhibited IL-9 release by NK cells. Additionally, activin A inhibited interferon (IFN)-γ production in splenic NK cells in mice, but promoted IL-2 production, and did not alter the production of IL-10. Western blotting results showed that levels of activin type IIA receptor (ActRIIA), Smad3 and phosphorylated-Smad3 (p-SMAD3) protein increased in activin A-treated splenic NK cells, compared with that in control NK cells. The inhibitory effects of activin A on IL-9 production by NK cells were attenuated in the presence of activin antagonist follistatin (FST) or Smad3 knockdown to NK cells. These data suggest that although activin A up-regulates IL-9 expression in Th cells, it inhibits IL-9 production in NK cells through Smad3 signaling.

Authors: Wang Libo , Xu Guigui 
Published: August 2019

Abstract
In this paper, we consider an N-species Gilpin–Ayala impulsive competition system. By using comparison theorem, Lyapunov functional, and almost periodic functional hull theory of the impulsive differential equations, this paper gives some new sufficient conditions for the permanence, global asymptotical stability, and almost periodic solution of the model. Our results extend some previously known results. The method used in this paper provides a possible method to study the permanence, global asymptotical stability, and almost periodic solution of the models with impulsive perturbations in biological populations.

Abstract
We study the existence of multiple positive solutions for a nonlinear singular Riemann–Liouville fractional differential equation with sign-changing nonlinearity, subject to Riemann–Stieltjes boundary conditions which contain fractional derivatives. In the proof of our main theorem, we use various height functions of the nonlinearity of equation defined on special bounded sets, and two theorems from the fixed point index theory.

Two separate 10 Gbit/s–10 GHz information signals are transported successfully over 30 km link range using distinct Hermite Gaussian (HG) modes. Also, the decomposition of distinct modes at the receiver terminal has been reported in this work. Furthermore, the impact of different fog conditions and scintillation effect on the performance of the proposed link has also been discussed in this paper.
A Brief Review on the Methods that Improve Optical Burst Switching Network Performance
Authors: Poorzare Reza , Abedidarabad Siamak 
Published: August 2019

Abstract
In this tutorial, we give an introduction to optical burst switching (OBS) networks and compare different methods that have been given to improve performance of these networks. OBS is an alternative to optical circuit switching and optical packet switching by separating data from control packets and sending them in a different wavelength. OBS networks suffer from an issue based on their bufferless nature, burst contentions. In these networks, when two data bursts are competing on the same wavelength, one of them is dropped and it leads to a significant reduction on the performance of the network. A lot of researches have been done to solve this problem. Some of them are addressed in this paper.

Published: August 2019

Abstract
Long-haul 16-channel dense-wavelength division multiplexing networks employing two different avalanche photodiode (APD) structures (Si and InGaAs) and positive-intrinsic-negative (PIN) photodetectors are simulated and compared under thermal noise effects for different fiber lengths. The effect of thermal noise level on the transmission quality with a variation of amplifying section length, number of amplifying sections and channel speed is discussed. The impact of thermal noise on the system performance is analyzed by varying input power from −5dBm to 20dBm for both 25 km and 50 km amplifying section at 100 km fiber length. The performance is evaluated for both 5 Gb/s and 10 Gb/s data rates over transmission distances up to 500 km. A comprehensive comparison is developed based on signal-to-noise ratio (SNR), quality factor (Q-factor) and bit error rate (BER). It is found that both APD structures achieve superior performance up to distance of 350 km comparing to PIN photodetectors for 50 km amplifying section. The system provides optimum performance at input power P
in = 10dBm in case of 50 km amplifying section, but then afterwards, the performance is degraded rapidly due to nonlinearities. The results revealed that the worst performance scenario is at 10–18 W/Hz thermal noise in terms of higher BER and lower Q-factor. Finally, the desirable BER of 10–12 is achieved at Q-factor of 6.78 and SNR of 23 dB.

Published: August 2019

Abstract
Wavelength division multiplexing (WDM) is a very important technique to utilize the bandwidth of optical fiber; multiple channels can be transmitted in the same fiber cable at the same time, and each channel has individual wavelength. At different network node, it’s required to add or drop wavelength, wavelength converter process is a technique responsible for converting the wavelength of signal to other wavelength up or down from the original value. This paper has presented a proposed model to generate inverted and non-inverted wavelength conversion by using single wide band traveling wave semiconductor optical amplifier (WBSOA), based on cross-gain modulation. The investigation of conversion efficiency (η) and quality factor (Q), versus pump power ranged value from −30 to 0 dB m, and input signal power is 0 dB m with data rate 25 Gb/s, are studied for up and down-wavelength conversion, “co-propagation” and “counter-propagation”, respectively. The simulation results indicate that, to get maximum conversion efficiency and maximum quality factor by using single WBSOA, the pump power should be located between −30 to −20 dB m for maximum conversion efficiency and equal to −10 dB m for maximum quality factor, that for up- and down-wavelength conversion, co-propagation and counter-propagation.
