Adaptation of Multi-platform Broadcasting Management in the Disruption Era: A Case Study of Private Television in Indonesia
Authors: Setiadi Anggi Arifudin , Afifi Subhan , Suparno Basuki Agus 
Published: July 2023

The disruption era is characterized by massive, rapid and unpatterned changes, causing uncertainty, unclear direction and complex relationships between factors driving the change. This epoch is accelerated by the massive use of digital technology with several main characteristics, such as the increasing importance of artificial intelligence, the internet of things, virtual reality, and three-dimensional printing machines. Such rapid changes require private television managers to adapt broadcasting practices to capture opportunities and anticipate threats. Taking a case study of private television in Indonesia, this article explores how multiplatform broadcast media adjust to such rapid changes. Applying the value chain concept as a theoretical framework, this study investigates five essential aspects of the broadcast production chain: content creation, packaging, scheduling, distribution platform, and user interface. The research method was descriptive qualitative with in-depth interviews, observations, and documentation studies as the primary data collection methods. This study shows that the packaging aspect is a new strategy in multiplatform broadcasting management by determining the target audience of a packaged program. The user interface strategy using multiple platforms allows the interaction with the audience. The broadcasting work management system using Trello enables television workers to work anywhere without coming to the office. Flexibility and time efficiency are applied in broadcasting work management. At the same time, the target market of the millennial generation who rarely watches television but watches YouTube broadcasts is responded by designing programs and channels that are more suited to the millennial character. Keywords: Multiplatform broadcasting management, disruption era, broadcasting value chain, private television

Authors: Prasetyo Ezra Julang , Hartomo Kristoko Dwi 
Published: July 2023

After the Covid-19 pandemic, the number of investors in Indonesia has proliferated. In managing a good stock portfolio, investors need the right strategy too. One approach that can be applied is to predict stock movements by considering the company's industrial sector. This paper proposed a new framework for applying deep transfer learning for stock forecasting in multi-industry. The model used in the framework is a combined algorithm between Gated Recurrent Unit (GRU) and Long-Short Term Memory (LSTM). The author built the pre-trained model using Indeks Harga Saham Gabungan (IHSG) and transferred it to predict Indonesia's stock indexes based on industry classification (IDX-IC) as the measurer of stock movement in multiple industries. The outcomes reveal that this framework produces good model predictions and can be used to help analyze the evaluation of the pre-trained model to conduct transfer learning stock prediction in different industries efficiently. The model built using the IHSG indexes can predict stock prices best in the energy, technology, and industrial sectors.

Technology Focus: Acidizing (June 2023)
Authors: Abbasy Imran 
Published: July 2023

The first acid job dates to 1895. Challenges remain, however, when it comes to lithology, coverage, penetration, and management of reaction products. These themes remain a focus for stimulation engineers.
In paper SPE 204879, for example, a novel in-situ foam-generation system is introduced that provides effective diversion and leaves no residue. Field applications suggest significantly better performance compared with other diversion systems. In paper SPE 203985, the authors present a 3D acid-fracturing model to calculate fracture geometry induced through multistage alternating injection of pad and acid fluids. Alternating acid with high-viscosity polymer pad promotes nonuniform acid etching and viscous fingering, which leads to longer and narrower channels. Concurrently, investigators are studying methods to achieve effective near-wellbore and far-field bridging using a combination of solids and fiber-laden acid. For those wishing to delve deeper into this subject, paper SPE 206255 makes interesting reading.
Completions can play a role in improving acid treatments. Limited entry, as presented in paper SPE 211394, and the so-called “segmented and selective” completions are at the forefront. Paper IPTC 23003 introduces the concept of sweet spots, which are then completed selectively with packers and sliding sleeves. Paper SPE 213406 describes a relatively complex architecture for a trilateral TAML Level 2 well with openhole packers and ball-activated sleeves. Thus, it can be said that most enabling technology is out there.
Lastly, engineers have begun to leverage benefits that big data and artificial intelligence potentially offer. Predicting an outcome of an acid job remains hit-and-miss at best—a gap engineers must bridge. In paper SPE 208172, the authors present a predictive model to estimate the efficiency of acid-fracturing treatments in naturally fractured reservoirs using an artificial neural network. They report a predictability error of less than 10%. This may be what we are looking for.
I hope you find the selections enlightening.

Effect of Grain Size Distribution on Pore Size Distribution Characteristics in a Conglomerate Reservoir from an Alluvial Fan Via Artificial Rock Approach
Authors: Gao Wenbin , Li Yiqiang , Kong Debin , Luan Huoxin , Chen Xin , Qi Huan , Tang Xiang 
Published: July 2023

Summary
Conglomerate is characterized by a multiscale grain stacking structure and various pore size distribution modes (PSDMs), significantly affecting multiphase fluid movement and transport in porous media. The multimodal structure and complicated PSDM are related to grain size distribution. However, the relationship between grain size distribution and pore structure characteristics remains unclear, which makes it hard to investigate using natural rocks affected by a single factor. Herein, a newly developed full-pore-scale artificial rock approach was used in this work to provide the ideal samples for experimental research. A bimodal distribution model was adopted to characterize the grain size distribution features quantitatively. Furthermore, the relationship between lithofacies, permeability, and PSDM was analyzed. The results demonstrate that grain size distribution includes coarse grain distribution (CGD) and fine grain distribution (FGD). As the average value of FGD increases, the permeability of conglomerate and sandstone have different decreasing trends. The increases in the grain size difference between CGD and FGD can decrease the most frequent and average pore radius, while the PSDM of conglomerate transforms from a steep peak shape to a hill shape. Furthermore, PSDM relates to permeability and lithofacies in an alluvial fan environment. The maximum permeability of sandstone with PSDM of hill shape is about 40 md while that of conglomerate is about 70 md. The grain and pore size distribution of artificial rocks is highly similar to that of natural rocks compared with natural rocks within the alluvial fan of Karamay conglomerate reservoirs. The findings are significant for robust determination in reservoir evaluation and development.
Monitoring and Characterization of Gas Migration in Oil-Based Mud Using Fiber-Optic DAS and DTS
Authors: Adeyemi Temitayo , Sharma Jyotsna , Tabjula Jagadeeshwar 
Published: July 2023

Summary
Understanding gas dynamics in mud is essential for planning well control operations, improving the reliability of riser gas handling procedures, and optimizing drilling techniques, such as the pressurized mud cap drilling (PMCD) method. However, gas rise behavior in mud is not fully understood due to the inability to create an experimental setup that approximates gas migration at full-scale annular conditions. As a result, there is a discrepancy between the gas migration velocities observed in the field as compared to analytical estimates. This study bridges this gap by using distributed fiber-optic sensors (DFOS) for in-situ monitoring and analysis of gas dynamics in mud at the well scale.
DFOS offers a paradigm shift for monitoring applications by providing real-time measurements along the entire length of the installed fiber at high spatial and temporal resolution. Thus, it can enable in-situ monitoring of the dynamic events in the entire wellbore, which may not be fully captured using discrete gauges. This study is the first well-scale investigation of gas migration dynamics in oil-based mud with solids, using optical fiber-based distributed acoustic sensing (DAS) and distributed temperature sensing (DTS).
Four multiphase flow experiments conducted in a 5,163-ft-deep wellbore with oil-based mud and nitrogen at different gas injection rates and bottomhole pressure conditions are analyzed. The presence of solids in the mud increased the background noise in the acquired DFOS measurements, thereby necessitating the development and deployment of novel time- and frequency-domain signal processing techniques to clearly visualize the gas signature and minimize the background noise. Gas rise velocities estimated independently using DAS and DTS showed good agreement with the gas velocity estimated using downhole pressure gauges.
Experimental investigation of the influence of different nozzle exit geometries on the depositing of strands in fused layer modeling
Authors: Krampe Michael , Kuhlenkötter Bernd 
Published: July 2023

Abstract
The aim of this paper is to investigate the influence of different exit geometries of the nozzle in the FLM process. In order to determine the effects of nozzle exit shapes, an experimental investigation was carried out. Individual strands were deposited with different nozzle exit shapes, whose shape was sub-sequently determined by laser scanning and microscopic images of the strand cross-sections. In addition, the orientation in relation to the deposition direction and five different layer heights were investigated. Circular, triangular, square, and hexagonal nozzle exit shapes with cross-sectional areas equivalent to a cir-cle of 1 mm, 0.8 mm and 0.6 mm diameter were prepared for these tests. Strands were printed with these different geometries and then scanned with a laser scanner and examined in cross-section with an optical microscope. After-wards, the strand shapes were compared with each other using the created pro-files and strand cross-sections. The results show that different geometries of the nozzle exit lead to different shapes of strand cross sections. It can be observed that the deviation from the cross section of the circular nozzle decreases with an increase in the number of corners of the nozzle geometry. Furthermore, the ex-tent of the deviation increases with increasing layer height. In addition to the outlet shape, a different orientation of the same nozzle leads to a deviating strand cross-section. Especially with the triangular nozzle exit geometry, this made a big difference in the shape of the deposited strand.
Evidence of Zelkova carpinifolia as a potential host of Tuber uncinatum from the Quaternary of Hyrcanian temperate forests
Authors: Azar Saeed Mirzavash , Riahi Hossein 
Published: July 2023

Abstract

Tuber uncinatum (Tuberaceae, Pezizales) is a commercially important ectomycorrhizal (EcM) fungal species associated with many deciduous EcM host species belonging to the Fagales lineage. Because of its host multiplicity among deciduous species, we hypothesized that it might associate with other plant lineages of Rosids as the most recent common ancestral of the ectomycorrhizae (MRCA-EcM) of Ulmaceae radiated preceding Fagaceae. The samples (host plant specimens, fungal ascomata, and soil) were from homogeneous Caucasian elm populations of the Hyrcanian temperate forests of Iran. Diagnosing the host plant was performed by using available botanical sources. The EcM symbiosis evidence and EcMF identity were illustrated by surveying gleba, spore shape, and EcM root anatomy using SEM, light, and stereo-microscopy, followed by molecular analysis. The micrographs obtained from root examination demonstrated the Hartig net penetration among cortical and epidermal cells and the presence of mantle as the EcM sheath. This study supports the EcM symbiosis of T. uncinatum with Zelkova carpinifolia from the Quaternary period in the Hyrcanian temperate forests.

Published: July 2023

Abstract
Back ground: In developing countries like Ethiopia, pneumonia is the leading cause of illness and death among children under five years old. Despite this, efforts to identify determinants of pneumonia in the study area are limited. This study aimed to identify determinants of pneumonia among under-five children in Shashemene, Oromia, Southern Ethiopia, 2021
Methods: An institution-based case-control study of 367 subjects was conducted from June 4 to June 25, 2021, in two hospitals in Shashemene city. The cases were children with pneumonia. Controls were children under the age of five years without pneumonia. After the total sample size was proportionally distributed among the hospitals, a consecutive sampling technique was used to select cases and controls. Epi-data version 3.1 was used to enter data and exported to SPSS version 25 for analysis. Descriptive statistical analysis was performed for selected variables. Variables with P < 0.25 and P < 0.05 with 95% CI in the multivariable logistic model were considered significant.
Result: Children less than 12 months of age (AOR 3,59 [1.99-6.49]), children with low birth weight (AOR 3,59 [1.99-6.49]) , history of upper respiratory tract infection within 2 weeks before study (3,76 [2.25-6.27]), inappropriate hand washing (AOR 2.32, 95% CI [1.35-3.98]), preparing food in the main house (AOR 3.37, 95%CI(1.86-6.09), household using wood/charcoal as fuel (AOR 1.89, 95% CI(1.06_3.36) were more likely to develop pneumonia and less among likely among children exclusively breastfeed in the first 6 months (AOR=0.43, 95%CI0.22-0.84) as compared to their counterparts.
Conclusion: This study found that age less than 12 months, underweight for age, upper respiratory tract infection in past two weeks, exclusive breastfeeding, lack of separate kitchen, use of wood/charcoal for food preparation, and maternal handwashing practice were determinants of pneumonia. Thus, focus on children under 1 year of age, improve early control of upper respiratory infections, and improve nutrition for young children. Furthermore, improving compliance with proper handwashing with soap among mothers/caregivers should be emphasized, and proper use of fuel for domestic purposes and separating cooking food could have a significant impact on reducing pneumonia.
Optimization of servo accuracy of Y axis of dicing saw based on iterative learning control

Published: July 2023

Abstract
The dicing saw is a critical equipment in the semiconductor industry, where the servo performance of each axis affects the dicing accuracy. Due to the primary motion direction of the Y-axis, the servo accuracy required is particularly high. This paper proposes a Variable Forgetting Factor Fuzzy Iterative Learning Control (VFF-FILC) with a Tracking Differentiator (TD), which can optimize the motor position loop of the Y-axis in the Israeli ADT-8230 dual-axis grinding wheel dicing saw. By combining fuzzy control and iterative learning control (ILC), this strategy overcomes the limitations of traditional PID controllers. The VFF-FILC reduces overshoot and settling time while improves tracking performance by adaptively adjusting the learning rate of the ILC algorithm based on the system's tracking inaccuracy. TD improves parameter uncertainty, robustness and tracking accuracy. To verify the superiority of our proposed design, we compare it with three traditional controllers and conduct Anti-interference experiments. The results of the study show that the proposed method is more responsive, more robust and has less tracking error than traditional methods.
GenX uptake by wheat and flooded and non-flooded rice: greenhouse experiment.

Published: July 2023

Abstract
GenX (hexafluoropropylene oxide dimer acid) belongs to the group of per- and poly-fluoroalkyl substance (PFAS) compounds introduced to replace perfluorooctanoic acid (PFOA), which has been phased out in industrial and consumer product formulations. While GenX has been investigated in lab animals, there is limited information available regarding its uptake and translocation in wheat and rice. This study reports on a greenhouse experiment in which wheat and rice grown under flooded and non-flooded conditions were exposed to two GenX concentrations in the soil (0.4 mg kg− 1 and 2 mg kg− 1). GenX was analysed in the soil, porewater and shoots using targeted liquid chromatography-tandem mass spectroscopy (LC-MS/MS) analysis. Extractable organic fluorine (EOF) was determined using high-resolution continuum source graphite furnace molecular absorption spectrometry (HR GFMAS). Results showed that different species took up different amounts of GenX. The GenX in rice shoots was found to be 2.34 (± 0.45) µg g− 1 and 4.11 (± 0.87) µg g− 1 under flooded and non-flooded conditions, respectively, at a low exposure level. At high exposure, the GenX concentrations in flooded and non-flooded rice shoots increased threefold to 10.4 (± 0.41) and 13.4 (± 0.72) µg g− 1, respectively. Wheat shoots showed similar concentrations and increases between low- and high-level exposure. The translocation factor was significantly higher (P = 0.013) in non-flooded rice compared to flooded rice. The GenX bioaccumulation behaviours under the same culture conditions (e.g. temperature, humidity, light, same GenX concentration in the soil) were significantly different in non-flooded and flooded rice (P < 0.001). Non-flooded rice plants displayed a higher level of GenX bioaccumulation than flooded ones. Following exposure to GenX, flooded rice plants showed a reduction in biomass (25%) compared to the control plants (P < 0.014). Our findings indicate that GenX is a bioaccumulative compound, the presence of which likely inhibits the growth of plants.
Dynamic Curvature of a Steel Catenary Riser on Elastic Seabed Considering Trench Shoulder Effects: an Analytical Model
Authors: Shoghi Rahim , Shiri Hodjat , Pesce Celso P. 
Published: July 2023

Abstract
Prediction of the fatigue life of steel catenary risers (SCR) in the touchdown zone is a challenging engineering design aspect of these popular elements. It is publically accepted that the gradual trench formation underneath the SCR due to cyclic oscillations may affect the fatigue life of the riser. However, due to the complex nature of the several mechanisms involving three different domains of the riser, seabed soil, and seawater, there is still no strong agreement on the beneficial or detrimental effects of the trench on the riser fatigue. Seabed soil stiffness and trench geometry play crucial roles in the accumulation of fatigue damage in the touchdown zone. There are several studies about the effect of seabed soil stiffness on fatigue. However, recent studies have proven the significance of trench geometry and identified the touchdown point oscillation amplitude as a key factor. In this study, a boundary layer solution was adapted to obtain the dynamic curvature oscillation of the riser in the touchdown zone (TDZ) on different areas of seabed trenches with a range of seabed stiffness. The proposed analytical model was validated against advanced finite element analysis using a commercial software. A range of seabed stiffness was examined and the corresponding fatigue responses were compared. It was observed that in the elastic seabed, the effect of soil stiffness is attributed to the curvature oscillation amplitude and to the minimum local dynamic curvature that SCR can take in the touchdown zone. The proposed analytical model was found to be a simple and reliable tool for riser configuration studies with trench effects, particularly at the early stages of riser engineering design practice.
