AbstractIt is known that the day-night shift-rotation has a negative impact on the immune system. The underlying mechanism remains to be further investigated. Probiotics have regulatory effects on immune functions. This study aims to investigate the role of probiotic ingestion in preventing the DEC205+ dendritic cell (decDC) dysfunction in day-night shift-engaging nurses. In this study, blood samples were collected from day-night shift-rotating nurses who took or did not take yogurt (containing C. Butyricum) during the night shift (NS). decDC functions were evaluated with pertinent immunological approaches. We observed that the immune tolerogenic functions and interleukin (IL)-10 expression were impaired in decDCs of nurses after NS. HDAC11 was detected in decDCs that was markedly up regulated after NS. The HDAC11 levels were negatively correlated with the immune tolerogenic functions in decDCs. Ingestion of probiotic-containing yogurt during NS efficiently suppressed Bmal1 and HDAC11 levels as well as up regulated the immune regulatory functions in decDCs. In conclusion, NS has a negative impact on decDC immune tolerogenic functions, which can be prevented by ingesting probiotics-containing yogurt during NS.
The influence of DNA methylation on monoallelic expression
Authors: da Rocha Simão Teixeira , Gendrel Anne-Valerie 
Published: November 2019

Abstract
Monoallelic gene expression occurs in diploid cells when only one of the two alleles of a gene is active. There are three main classes of genes that display monoallelic expression in mammalian genomes: (1) imprinted genes that are monoallelically expressed in a parent-of-origin dependent manner; (2) X-linked genes that undergo random X-chromosome inactivation in female cells; (3) random monoallelically expressed single and clustered genes located on autosomes. The heritability of monoallelic expression patterns during cell divisions implies that epigenetic mechanisms are involved in the cellular memory of these expression states. Among these, methylation of CpG sites on DNA is one of the best described modification to explain somatic inheritance. Here, we discuss the relevance of DNA methylation for the establishment and maintenance of monoallelic expression patterns among these three groups of genes, and how this is intrinsically linked to development and cellular states.
The role and mechanisms of DNA methylation in the oocyte
Authors: Sendžikaitė Gintarė , Kelsey Gavin 
Published: November 2019

Abstract
Epigenetic information in the mammalian oocyte has the potential to be transmitted to the next generation and influence gene expression; this occurs naturally in the case of imprinted genes. Therefore, it is important to understand how epigenetic information is patterned during oocyte development and growth. Here, we review the current state of knowledge of de novo DNA methylation mechanisms in the oocyte: how a distinctive gene-body methylation pattern is created, and the extent to which the DNA methylation machinery reads chromatin states. Recent epigenomic studies building on advances in ultra-low input chromatin profiling methods, coupled with genetic studies, have started to allow a detailed interrogation of the interplay between DNA methylation establishment and chromatin states; however, a full mechanistic description awaits.
Recherche en Orthopédie Dento-Faciale : les erreurs statistiques à éviter
Authors: Oueiss Arlette , Faure Jacques 
Published: November 2019

L’Evidence Based Medecine (EBM) a contribué à obliger les chercheurs à une exigence de rigueur accrue. Les Revues Scientifiques ont participé à cette évolution par une plus grande sévérité dans la sélection des articles.
Le nombre des articles refusés (75%) pour certaines publications) et la dénonciation fréquente, parmi les raisons de rejet, des failles dans le traitement statistique, incitent à la réflexion développée ici, qui aborde successivement :
Les erreurs liées aux premières étapes du protocole (sélection des échantillons, choix des VA…).Les déficits concernant les statistiques descriptives et la mise en œuvre des statistiques élémentaires au niveau d’un pré-protocole…
Enfin le manque de communication avec le statisticien aguerri en charge des statistiques complexes et/ou spécifiques qui conduisent à la compréhension intime des relations internes (inter-paramètres) au sein du fichier-source.
Les auteurs conseillent aux jeunes chercheurs en charge d’une base de données importante d’être vigilants à trois moments :
Considérez attentivement les mesures à réaliser, les échantillons à réunir, les paramètres à utiliser, quels résultats vous attendez et quelle analyse vous envisagez.
Pensez à un pré-protocole sur quelques patients, avec mise en œuvre systématiques des outils usuels (accessibles sur tout logiciel et même sur un tableur) et examen attentif des statistiques descriptives et des rapprochements élémentaires (cœfficient de corrélation par exemple).

Secondary Management of Midface Fractures
Authors: Aman Hessah , Shokri Tom , Reddy Likith V. , Ducic Yadranko 
Published: November 2019

AbstractSecondary reconstruction of posttraumatic facial deformities has been consistently described as one of the most challenging procedures performed. Ideal primary reconstruction cannot always be achieved, and often it is complicated by severe comminution or inadequate surgical management. It also can arise because of a lack of definitive surgical repair or excessive delay of initial treatment. Complications leading to secondary deformities can occur even when craniofacial injuries are treated by experienced surgeons. Following proper surgical principles, meticulous perioperative planning, and anticipation of potential functional and aesthetic sequelae limit many of those complications. Herein, we discuss secondary procedures in traumatic midface injuries.

Abstract
Results of studying photoinduced changes of a refractive index in the core of a composite erbium-doped phosphorosilicate optical fibre under pulsed UV irradiation at a wavelength of 193 nm and the annealing of these changes are presented and analysed. It is shown that the preliminary saturation of a composite optical fibre by molecular hydrogen substantially increases the photosensitivity. Analysis of thermal anneal kinetics revealed fundamental differences in the photosensitivity mechanisms between the optical fibres saturated with hydrogen and not subjected to hydrogen treatment. Initial and photoinduced absorption spectra of the phosphorosilicate glass are investigated. It is found that in the UV range, the induced absorption is mainly determined by a contribution from the intense absorption band of photoinduced phosphorus electron centres PO2 with a maximum at 4.7 eV (λ = 260 nm).

Abstract
The possibility of producing a single-frequency fibre laser using a new type of fibre made by sintering phosphate glass in a silica glass tube (composite fibre) is demonstrated. In a fibre of this type, photosensitivity to laser radiation with a wavelength of 248 nm is detected. A fibre laser cavity is fabricated by writing fibre Bragg gratings directly in the core of the composite optical fibre activated by erbium ions. Stable single-frequency linearly polarised lasing regime is obtained at a wavelength of 1559.5 nm with a maximum output power of ∼3 mW.

Authors: Mel’nikov L.A. , Mazhirina Yu.A. 
Published: November 2019

Abstract
We report the results of numerical simulation of the radiation dynamics in a Raman fibre amplifier taking into account quantum fluctuations of the pump fields and Stokes waves. The simulation relies on an approach based on solutions of the transport equations for complex amplitudes and on the ‘backward’ propagation method for operators describing quantum fluctuations. It is shown that there exists an optimal Raman amplifier length corresponding to the minimum level of fluctuations of the amplified Stokes pulse.

Simulating general relativity and non-commutative geometry by non-paraxial quantum fluids
Authors: Marcucci Giulia , Conti Claudio 
Published: November 2019

Abstract
We show that quantum fluids enable experimental analogs of relativistic orbital precession in the presence of non-paraxial effects. The analysis is performed by the hydrodynamic limit of the Schrödinger equation. The non-commutating variables in the phase-space produce a precession and an acceleration of the orbital motion. The precession of the orbit is formally identical to the famous orbital precession of the perihelion of Mercury used by Einstein to validate the corrections of general relativity to Newton’s theory. In our case, the corrections are due to the modified uncertainty principle. The results may enable novel relativistic analogs in the laboratory, also including sub-Planckian phenomenology.

Authors: Kusumawati R , D’arofah A , Pramana P A 
Published: November 2019

Abstract
Tokopedia is one of the online shopping centers in Indonesian that carries the business model marketplace. Positive and negative opinions in Twitter from Tokopedia users about company services are source of information for the management. Naive Bayes Classification (NBC) and Support Vectore Machine (SVM) are techniques in data mining used to classify data or users opinion. The algorithm of NBC is very simple since it only use text frequency to compute the posterior probability for each classes. While SVM algorithm is more complex than NBC. SVM develop hyperplane equation which separate data into classes perfectly. The researcher wants to compare the performance of the NBC and SVM algorithms and use them to classify user opinions on Tokopedia’s services, because these two algorithms have different approaches and difficulty levels. Classification included positive and negative class only. Accuracy, precision and recall value are used to compare the performance of both algorithms. Research evaluation shows that SVM linear kernel technique outperform NBC technique with the accuracy 83.34%.
Application of Analytic Approximation Method Using HAM for Solving The Democratic Elections Model
Authors: Yong B 
Published: November 2019

Abstract
This article presents the solutions of the democratic elections model by homotopy analysis method (HAM). We proposed a simple democratic elections model in the form non-linear differential equation in a closed voters population. Voters population divided into three sub-population, i.e neutral sub-population, supportive sub-population, and aphatetic sub-population. HAM is applied to compute the solutions of the model. HAM is an analytic approximation method in the form of power series to solve the non-linear differential equation. HAM contains the auxiliary parameter for controlling the convergent region of power series solutions. Numerical simulations on the model in the form graphical results are presented and discussed quantitatively to describe the dynamics of each sub-population. It is shown that HAM performs well in terms of efficiency which converge rapidly and results obtained require only a few iterations.

Authors: Ishii Tsutomu 
Published: November 2019

Abstract
In this paper, we will consider about the reason of using Tablet PCs. Japanese teachers do not use Tablet PCs so much. The reason is the research question. Japanese Government is supporting financially for teachers to use the projectors and computers in the classroom. Recently, teachers using Tablet PCs are increasing, but there are teachers who do not use Tablet PCs, too. In the 1st step, several studies were considered. And we checked its educational possibility and expectation of Tablet PCs. For example, in early childhood showed that teaching with Tablet PCs contributed significantly to the development of children’s mathematical ability. In the 2nd step, we analyzed the mathematics class using Tablet PCs about the percentage of the elementary school 5th grade in Japan. We analysed carefully about understandings of children and instructions of teacher. In the 3rd step, as the case study, we considered whether instruction by Tablet PCs was proper in detail and we argued the result based on several studies. In this paper, at the end, we pointed out 2 points. First, children’s understanding deepens by Tablet PCs. Next, there is little contribution to bring the flexibility and creativity up.

Published: November 2019

Abstract
Being able to solve a variety of mathematical problems is one of the main factors and indicators that reflect the success of mathematics learning, including real-world problems. In solving real-world problems, students need a mathematical connection to be able to choose and use a mathematical concept that fits properly with conditions given in the problem. Therefore, it is important to observe students’ mathematical connection in order to improve their mathematical achievement. This study is qualitative descriptive which aimed to describe the ability of eighth-graders’ mathematical connections in solving real-world problems. The subjects of this study were 29 students of a Private Junior High School in Bantul Yogyakarta. Mathematical connection test was employed for collecting the data. Based on the analysis result, students’ mathematical connection falls in the low category. Students’ difficulties in solving real-world problems were restricted to understanding the problem and connecting the problem with relevant mathematical concepts.
Undergraduate students’ difficulties in proving mathematics

Published: November 2019

Abstract
This study aimed to find out the difficulties of proof experienced by undergraduate students. The type of research used was descriptive case studies. This research was conducted on 12 junior undergraduate students of the Mathematics Education Department at one of the universities in Yogyakarta. Data in this study were obtained through diagnostic tests and interviews. The most dominant difficulty in proving was the difficulty of construction and understanding the proof difficulties in constructing and evaluating mathematical proof. Those happened because undergraduate students were considered not able to integrate the existing proof by proving that it is done as a complete proof of a case. This difficulty was caused by a lack of accuracy or even prior knowledge that was not sufficient. Lack of relevant knowledge both in the use of theorems and notations was another case of difficulty in proving.
