AbstractA specific learning disorder (SLD) is a neurodevelopmental disorder in which academic skills, such as reading, writing, and mathematics ability, are below the expected range. This study was conducted to determine the relationship between spike-wave index and SLD in children. We recruited 110 child psychiatry outpatients (38 girls, 72 boys) with SLDs for this study between January 2015 and March 2018. The mean ± standard deviation patient age was 9.17 ± 1.87 years. Electroencephalography (EEG) findings were abnormal in 20.9% of children. We found that children with expressive language delay and who were born prematurely had a significantly higher risk of spike-wave index. Attention deficit/hyperactivity disorder was present in 55.5% of children with SLD. This comorbidity was significantly higher in children with a history of prenatal smoking exposure or premature birth. The EEG findings were particularly important in cases of SLD in children who were born prematurely and had expressive language delay. The spike-wave index is a potential marker of SLD and can be easily and noninvasively detected by EEG.

Objective This study aimed to assess risk for postpartum psychiatric admissions in the United States.
Study Design This study used the 2010 to 2014 Nationwide Readmissions Database to identify psychiatric admissions during the first 60 days after delivery hospitalization. Timing of admission after delivery discharge was determined. We fit multivariable log-linear regression models to assess the impact of psychiatric comorbidity on admission risk, adjusting for patient, obstetrical, and hospital factors.
Results Of 15.7 million deliveries from 2010 to 2014, 11,497 women (0.07%) were readmitted for a primary psychiatric diagnosis within 60 days postpartum. Psychiatric admissions occurred relatively consistently across 10-day periods after delivery hospitalization discharge. Psychiatric diagnoses were present among 5% of women at delivery but 40% of women who were readmitted postpartum for a psychiatric indication. In the adjusted model, women with psychiatric diagnoses at delivery hospitalization were 9.7 times more likely to be readmitted compared with those without psychiatric comorbidity. Women at highest risk for psychiatric admission were those with Medicare and Medicaid, in lower income quartiles, and of younger age.
Conclusion While a large proportion of psychiatric admissions occurred among a relatively small proportion of at-risk women, admissions occurred over a broad temporal period relative to other indications for postpartum admission.
Mitochondrial transcription factor A promotes DNA strand cleavage at abasic sites

Published: August 2019

Significance
Failure to maintain mitochondrial DNA (mtDNA) has been implicated in a variety of mitochondrial disorders and human diseases. mtDNA degradation is an important process for mtDNA maintenance and stress response; nevertheless, the mechanism by which mtDNA is degraded remains partially understood. We demonstrate that mitochondrial transcription factor A (TFAM) facilitates damaged DNA degradation by accelerating strand cleavage at abasic sites, reducing the half-life of abasic DNA by 2 to 3 orders of magnitude relative to free DNA. The TFAM-catalyzed AP-lesion destabilization occurs with nonspecific DNA or mitochondrial light-strand promoter sequence, facilitated by lysine residues of TFAM to form Schiff base intermediates. The catalytic effect of TFAM on abasic DNA suggests a novel role of TFAM in mtDNA metabolism.
Molecule counts in complex oligomers with single-molecule localization microscopy
Authors: Baldering Tim N , Bullerjahn Jakob T , Hummer Gerhard , Heilemann Mike , Malkusch Sebastian 
Published: August 2019

Abstract
Single-molecule localization microscopy resolves nano-scale protein clusters in cells, and in addition can extract protein copy numbers from within these clusters. A powerful approach for such molecular counting is the analysis of fluorophore blinking using stochastic model functions. Here, we develop a theoretical model for quantitative analysis of PALM data that accounts for the detection efficiency. By this, we are able to extract populations of different oligomers reliably and in complex mixtures. We demonstrate this approach analyzing simulated PALM data of a photoactivatable fluorescent protein. We generate simulations of blinking data of oligomers and of mixtures of oligomers, and show robust oligomer identification. In addition, we demonstrate this approach for experimental PALM data.
Monte Carlo calculation of beam quality correction factors in proton beams using PENH
Authors: Gomà Carles , Sterpin Edmond 
Published: August 2019

Abstract
This work calculates beam quality correction factors (

) in both modulated and unmodulated proton beams using the Monte Carlo (MC) code

. The latest ICRU 90 recommendations on key data for ionizing-radiation dosimetry were adopted to calculate the electronic stopping powers and to select the mean energy to create an ion pair in dry air (

). For modulated proton beams,

factors were calculated in the middle of a spread-out Bragg peak, while for monoenergetic proton beams they were calculated at the entrance region. Fifteen ionization chambers were simulated. The

factors calculated in this work were found to agree within 0.8% or better with the experimental data reported in the literature. For some ionization chambers, the simulation of proton nuclear interactions were found to have an effect on the

factors of up to 1%; while for some others, perturbation factors were found to differ from unity by more than 1%. In addition, the combined standard uncertainty in the MC calculated

factors in proton beams was estimated to be of the order of 1%. Thus, the results of this work seem to indicate that: (i) the simulation of proton nuclear interactions should be included in the MC calculation of

factors in proton beams, (ii) perturbation factors in proton beams should not be neglected, and (iii) the detailed MC simulation of ionization chambers allows for an accurate and precise calculation of

factors in clinical proton beams.

Abstract
Mangrove vegetation plays an important role and supplier of organic matter derived from litter fall and litter decomposition The purposes of this research was to obtain the productivity of mangrove vegetation by analyzing the litter fall, decomposition coefficient, and percentage of litter decomposed in the northern coast of Aceh Besar District. The research used purpossive sampling method to determine the 6 stations devided into 2 substations (landward and seaward). This research was conducted in July to September 2016. Each substation was put one of the litter trap. The litter trap method was used to know the mangrove litter production. Litter decomposition focused on R. mucronata leaves were studied by using litterbag technique. The litter bags were made of synthetic nylon which had size 20cm x 30cm and mesh size was 1 x 1.25 mm2. There were 3 types of mangrove found, litter production of Rhizophora mucronata as much as 79.21 g/m2/day, Avicennia marina as much as 0.70 g/m2/day and Sonneratia alba was 17.46 g/m2/day. Based on the substation influenced by tidal, mangrove litters found in the seaward higher than in the landward, the average litter fall was 52.05 g/m2/day and 43.32 g/m2/day. Result of mangrove decomposition showed that the percentage of decomposition for the 49th day in the seaward substation was 48.58% and the landward was 41.53%. Mangrove litter decomposition increased during the time at both substation. Decomposition rate of litter for Rhizopora mucronata species classified very quickly where the substation on the seaward was 0.012 (d−1) and landward was 0.010 (d−1). The half-time took in the leaf litter of mangroves for the landward was 69 days and seaward was 57 days, R. mucronata leaves litter decomposited in seaward substation was faster than landward.

Abstract
Stirred tanks are widely used for mixing to pseudo-plastic fluids in chemical, food and many processing industries. Impeller stirred tanks play a very important role throughout process industries. Design of such systems and the effective control of the relevant processes require an understanding and prediction of the flow characteristics. One technique to develop high efficiency of this fluid production such as bioethanol is to reduce the stagnant or dead zones formation phenomena inside the stirred tank using computational fluid dynamics. The results have shown that the new impeller design as dependent variables were able to eliminate the dead zone formation related with the independent variables such as power number P0
, pumping number N

q
, wall shear stress τ, mixing time τ, and average effective viscosity μ.
Heuristic approach for solving capacitated location-routing problems
Authors: Ahmad H N , Bakhtiar T , Supriyo P T 
Published: August 2019

Abstract
This paper deals with the standard capacitated location-routing problem (CLRP), where two types of interdependent decisions must be made: which facilities among a number of potential ones should be operated and which vehicle routes should be built to fulfil the demand of customers from the operated facilities using a given fleet. We propose a heuristic mechanism to address the problem. The algorithm consists of four stages, namely optimally clustering customers by k-means and assessed by Dunn index, selecting the nearest depot to be opened based on Euclidean distance calculation, customers-to-depot matching and searching the optimal distribution route. This heuristic algorithm is then implemented to a dataset comprises of 20 customers and 5 potential depot facility locations.

Published: August 2019

Abstract
In an insurance company, it is very possible that there is an imbalance between the amount of the premium and the amount of claims submitted by the insured. In managing the risk of such an imbalance, the insurance company must be able to make a decision to determine the appropriate amount of premium based on a number of claims by the insured. To make these decisions, insurance companies can do so by using certain utility functions. This paper examines the use of exponential utility functions in transferring risk between insurance companies, optimal Pareto exchanges, equilibrium, Bowley solutions, and optimal reinsurance purchases. Furthermore, using the exponential utility function is calculated the optimal amount of reimbursement that will be carried out by the insurer. The results of the discussion obtained the factors that influence the calculation and the optimal amount of reimbursement value, from a property policy or group policy that needs to be carried out by the insurer. So that based on the results of the optimal reimbursement calculation, it can be used to determine the balance between the amount of the premium and the amount of claims that may be submitted by the insured.

Authors: Iskandarov M , Khisamutdinov R 
Published: August 2019

Abstract
This article considers the first comprehensive introduction to simulation modeling of assembly systems, and considers the assumption that simulation is a reliable method for testing production and assembly systems. Simulation is an important software tool with which you can perform a large number of experiments with various system parameters. Simulation modeling allows to describe the structure of the system and its processes in a natural form, without resorting to use of complex formulas, equations, and strict mathematical dependencies. Modeling allows to detect and eliminate problems that manifest themselves in the early stages of commissioning the assembly system, which implies significant savings in costs and time [1]. This article provides a part of the theoretical base of the topic and a practical example of using modeling. For practical research software was used Tecnomatix Plant Simulation from the company SIEMENS.

Authors: Talibly L H , Imranov F B , Jafarova A M 
Published: August 2019

Abstract
The statement is formulated and the solution of the problem of determining the time of corrosion destruction of an elastic homogeneous plate with a deep bilateral external recess is given. A plate of corrosive material is subjected to bilateral stretching in a corrosive environment in a direction perpendicular to the axis of the recesses. The well-known solution of the problem of the stress state of this plate, obtained by H. Neuber, is used. The following cases are considered: a) the effect of stress, which occurs in the plate when it is stretched, on the corrosion process is negligible; b) the effect of plate voltage on the corrosion process is significant. In both cases, the dependences of the change in the area of the narrowest cross-section of the plate on time are found. The time of complete corrosion wear and the time of corrosion cracking of the plate before its complete wear are also determined.

A Conflict Index to Assess Traffic Safety at Intersections
Authors: Abdul Majeed Raghad Zeki , Ewadh Hussein A. 
Published: August 2019

Abstract
In this paper, a conflicts-based technique, using an index measure is introduced to assess traffic safety at intersections. The technique helps in identifying sites most probable to profit from safety improvement as an alternative to crashes-based analyses. As a case study, the analysis and measure of safety for 11 four-leg signalized intersections at different sites in Baghdad city, have been done independently using direct methods based on crash rate and indirect methods based on the level of conflict risk measures. A comparison is achieved between the two methods and their outputs. The study results imply that a developed method of conflicts index of signalized intersections (CISI) (based on traffic conflict frequency and severity) could serve as a viable way of measuring the safety performance of signalized intersection at urban area. CISI can be established for existing conditions at intersections as well as in evaluating different design alternatives to more accurate safety comparison and better decision-making. Application of direct and indirect method results in identifying the same sites to profit from safety improvement. In addition, the research demonstrates a promising application of CISI in; relative comparison of conflict risk at various intersections and estimating conflict risk after potential countermeasures for before-after assessment of traffic safety at intersections.

Authors: Al-Salakh Ahmed M. Sadeq , Albusoda Bushra Suhale 
Published: August 2019

Abstract
In liquefying soils, Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. Therefore, the buildings on shallow footings may settle and tilt excessively. In this paper, the bearing capacity and settlement of shallow foundation on liquefiable deposits has studied. The study includes a shaking table test, reviewing of theoretical equations (available in literature), which estimating settlement of shallow footings due to seismic loading, calibration, and verification of these equations with data from the shaking table test for improved soil by grouting and unimproved soil. It is important to note that the grouting materials used in this study are the CKD and Bentonite slurries. A modification to the seismic bearing capacity and settlement equations had been done to account for the liquefaction state. Good convergence has been gotten between predicted and measured settlement.

Authors: Rubaee Sara k AL , Rahman Ammar A Abdul 
Published: August 2019

Abstract
This paper studies the behavior of bridges’ superstructure under seismic action. The bridge under investigation is one of the typical bridges usually used in overpasses in Iraq, which is made of simply supported steel built up girders and reinforced concrete deck slab isolated from the substructure by elastomeric bearing pads. A three-dimensional finite element model was developed using CSI Bridge Software. Time history analysis was carried out using true-recorded earthquake took place in Iraq near the city of Halabja in 2017. The results of the analysis show that the displacements of the elastomeric bearing pads under transverse seismic loading are much higher than the permissible displacements’ limit which will produce failure of these bearings and potential failure of the bridge superstructure.
