Authors: Emanuel T , Hadrian  , Prayogo D , Wong F T 
Published: November 2021

Abstract
Steel deck floor systems can be considered as one of the main components of a structure. As technology advances, the role of optimization is used in many aspects of structural designs. Steel deck floor systems are one of many components that are usually optimized to look for its optimum cost but are still able to hold the structure. This study compares the performance of the particle swarm optimization (PSO), artificial bee colony (ABC), differential evolution (DE), and symbiotic organisms search (SOS), that categorized as nature-inspired algorithms, in the optimization of a steel deck floor system. The variables considered are the edge beams, interior beams, and the composite steel deck. The results show that the SOS gives the most optimum cost with a better average and a perfect success rate.

Authors: Wulandari P S , Tjandra D 
Published: November 2021

Abstract
Recycling tires is one of the eco-friendly way for reducing environmental problems. Incorporating crumb rubber in asphalt mixtures is an alternative way for reusing the end-of-life tires in road construction. The main purpose of this study is to evaluate the cold mix asphalt incorporating crumb rubber as a substitute for a part of fine aggregates. In this study, the aggregate gradations for mix design were selected according to the specification, Dense Graded Emulsion Mixtures (DGEM) Type IV and Open Graded Emulsion Mixtures (OGEM) Type E/20. The design bitumen content in this study was optimized for stability, void in mixture (porosity), and density. Crumb Rubber (CR) emulsion mixtures were made with optimum bitumen content at 8% by mass of total mixture for DGEM and OGEM. In order to incorporate crumb rubber into the cold emulsion mixtures, laboratory testing were performed for 25% and 50% of fine aggregates replaced with an equal volume of crumb rubber. In general, CR emulsion mixtures showed good results in all parameters. The CR emulsion mixtures also had a good comparison to hot mix asphalt specification for medium volume traffic loads with porosity less than 10%. From this study, crumb rubber can be recommended as a substitution material of fine aggregates in cold mix asphalt.

Abstract
Three-dimensional (3D)-printed concrete is believed to have a significant impact in the construction industry in the future. Some research has been conducted experimentally and analytically to investigate the structural behavior of 3D-printed concrete elements, such as beams. Previous study by the authors attempted to analytically model 3D-printed reinforced concrete (RC) beams failing in flexure that were tested by other researchers. The study was done with the aid of a finite element software. However, there are some limitations of the analytical model to simulate the failure mode of the specimens. In this study, an improvement of the analytical model is proposed in order to simulate the behavior of the 3D-printed RC beams more accurately. Furthermore, the analysis was also expanded for 3D-printed prestressed concrete (PC) beam. From the analysis results, it can be concluded that the improved analytical model is able to predict more accurately the failure mode as well as the hysteretic behavior of the 3D-printed RC beams. Nevertheless, a more sophisticated analytical model is needed to improve the accuracy of the prediction for the 3D-printed PC beam.

Abstract
The main problem related to thermal condition in Surabaya as a second-largest city in Indonesia is humid and hot. It is a typical condition of tropical climate. Ventilation in the hot day will bring warm and humid outdoor air into a room. It will increase the temperature of air in the room. One of some efforts to reduce the outdoor air temperature is using an earth to air heat exchanger (EAHE) to transfer heat from the air to the earth or ground. This paper will discuss about research done to study the effect of EAHE to a room temperature. The study used two model rooms which are similar and a model EAHE. One room called condition room will receive air flowing from the EAHE pipe and the other room is called the referent room. From the research, it is found that the air in condition room with EAHE is cooler in the daytime compared to the referent room. The temperature of the condition room with EAHE is more stable.
Comparison of simulation-based methods and metaheuristic optimization algorithms for optimizing window design by considering daylighting and heat transfer in a tropical region of Indonesia
Authors: Budhiyanto A , Oktavianus A , Tedjokusumo B , Harsono K , Yang I T 
Published: November 2021

Abstract
This study presents evaluation and comparison of simulation-based methods and metaheuristic optimization algorithms on building design models, focussing on daylight availability maximization and energy consumption minimization. The simulation-based method was presented using Rhino/Grasshopper software supported by the Ladybug, Honeybee, and Octopus optimization plugins; while MOPSO was chosen to calculate the metaheuristic optimization algorithm. The result indicated that OTTV values of the optimum design were respectively in the range of 24.06 W/m2 to 34.15 W/m2 for Octopus optimization and 25.19 W/m2 to 34.99 W/m2 for MPSO; and the WWR value for Octopus optimization and MOPSO were in the range 15% to 23% and 15% to 26%, respectively. While both methods showed similar results, the time duration for simulating in Rhino/Grasshopper was much longer compared to calculating the algorithm using MATLAB, indicating that simulation-based was less effective.
The uniformity concept of urban design: impact of cultural traditions on the meaning of Balinese town
Authors: Mahira E D , Soemardiono B , Santoso E B 
Published: November 2021

Abstract
This study considers the conceptions of religion, tradition, and culture in the urban design process, to produce designs that become the identity of cities in Bali. A socio-semiotic approach is used to explore popular accounts of the conceptions of tradition operating in urban spatial arrangements from historical to contemporary periods. The case study in Gianyar City explores the meaning of urban space based on local wisdom that is still believed by Balinese people. Such exploration provides a basis for reconnecting urban designs with their cultural contexts, thereby promoting spatially expressed localism. Especially for Gianyar City, respect for religious systems, beliefs, and religions that have developed and are highly trusted by the public is expressed in symbolic elements that are embodied in the composition of space, and in fact, give rise to the concept of uniformity. This condition resulted in not achieving a more prominent urban cultural identity and being further damaged by the highly standardized process in the Indonesian planning system. However, the principles of religion and culture that are still alive make Balinese architecture alive, despite changing values, whether we realize it or not.
Reinterpreting local wisdom of Rumah Kaki Seribu as sustainable architecture
Authors: Prabaswara B C , Hariyanto L , Arifin L S 
Published: November 2021

Abstract
Awareness of the increasing global issues regarding global warming and climate change has encouraged building designers to look back on knowledge of traditional architecture as energy-efficient and sustainable solutions. This study focuses on the traditional architecture of Rumah Kaki Seribu as sustainable architecture. Rumah Kaki Seribu is a traditional architecture located in the Arfak Mountains, West Papua, inhabited by the Arfak Tribe. Each architectural element of Rumah Kaki Seribu has a different sustainability value. The sustainability value of Rumah Kaki Seribu discussed is the concentration on the fireplace element and the roof element. The fireplace and roof elements were analyzed using the eco-cultural concept of the six competing logics of sustainable architecture by Simon Guy and Graham Farmer. Eco-cultural logic is a logic that is closely related to traditional architecture. The characteristics of sustainable buildings that use eco-cultural logic can be determined by looking at several parameters, namely the image of space, the source of environmental knowledge, the building image, technologies, and the idealized concept of place. The study aims to learn traditional architecture as a design approach to understand and respect the environmental context for solutions to global issues that occur.
Actual and expected transactional and transformational leadership behaviors of project managers
Authors: Andi A , Sugianto K , Khoesasih A F 
Published: November 2021

Abstract
In order to ensure that construction team works toward the desired objective, it is important for a project manager to behave as an effective project team leader. This paper aims to investigate actual and expected leadership of project managers by comparing the transactional and transformational leadership behavior model. To accomplish the objective, the paper first briefly reviews the ways in which leadership, especially the two models, are approached. Data were collected through a survey to 63 construction team members in several ongoing projects in Indonesia. The results indicate that the project managers frequently use both transactional and transformational behaviors in leading their team, except the laissez-faire style. Results from analytical hierarchy process analyses interestingly show that the project team members expect the project managers to exhibit transformational leadership more than transactional leadership.

Published: November 2021

Abstract
To some people, back-in parking maneuver is a relatively hard thing to do. However, previous studies have proven that back-in parking is safer than head-in parking because when exiting the parking space (back-out) from head-in parking, the driver's field of view is more limited, thus increasing the chance of an accident. This study aims to determine the changes in the driver's viewing frequency on the rear-view mirror, maneuver duration, and degree of difficulty during back-in parking maneuvers. Data collection was obtained from 45 participants who tried to park their cars in a parking space with an angle of 30°, 45°, 60°, 90°, each with four different conditions of parking spaces. The driver’s viewing frequency on each rear-view mirror (left, right and center) and maneuver duration were obtained from a dashcam and an external camera recording. The difficulty level for maneuvering was filed according to the driver’s opinion during the experiment for each parking space condition. Based on the data analysis, it was proven that the existence of cars parked on either side of that parking space (obstacles), parking space line signs, and both simultaneously increase the driver’s viewing frequency and maneuver duration when doing back-in parking maneuver, but at the same time, ease the parking maneuver, according to the driver.
Potential damage to residential building due to adjacent surcharge fill loading-case studies in Surabaya, Indonesia

Published: November 2021

Abstract
Housing construction is a common construction activity and is always needed from time to time. House construction can be in the form of building new house or renovating an existing building. The impact of construction work to adjacent building or structure is something that cannot be avoided but must be minimized. The case study in this research aims to increase the awareness of all parties in construction project related to the potential damage to the surrounding buildings that may occur. This research was conducted with a case study on the construction of residential houses in Case A and Case B located in Surabaya-Indonesia. Field observations, analysis of damage causes, rectification methods and estimated cost were carried out in this study. These two case studies presented the damages analysis on residential house due to settlement which caused by adjacent surcharge fill loading. This settlement causes a differential settlement on both sides of the existing building, which had impacts on floor slope and cracks in wall. Proposed rectification works were made to restore the house to reach minimum serviceability requirement and prevent further damage in the future. The cost of repairing and retrofitting the damage existing house significantly increases the budget for a new house construction project. Therefore, careful planning in construction project considering the impact of soil settlement is needed more attention, especially in a dense urban area. Good communication and coordination between contractors and owners of neighbouring building are also needed to minimize the potential conflicts during or after construction works.
Limits for scattering resonances in azimuthally inhomogeneous nanotubes
Authors: Valagiannopoulos Constantinos , Sihvola Ari 
Published: November 2021

Abstract
Resonant electromagnetic scattering has been optimized for angularly inhomogeneous nanotubes characterized by different surface admittances along the two complementary arcs. The optimal designs are substantially more efficient compared to their best homogeneous counterparts and the spatial distribution of the scattering power reveals the nature of the sustained resonances. In this sense, the reported scattering scores constitute limits for the response of that simple class of structures and can be employed as optimized components in a wide spectrum of photonic devices from wave transformers and field sensors to electromagnetic filters and optical lenses.
‘Truth in Fiction’ Reprised
Authors: García-Carpintero Manuel 
Published: November 2021

AbstractThe paper surveys recent appraisals of David Lewis’s seminal paper on truth in fiction. It examines variations on standard criticisms of Lewis’s account, aiming to show that, if developed as Lewis suggests in his 1983 Postscript A, his proposals on the topic are—as Hanley puts it—‘as good as it gets’. Thus elaborated, Lewis’s account can resist the objections, and it offers a better picture of fictional discourse than recent resurrections of other classic works of the 1970s by Kripke, van Inwagen and Searle. The turn that Lewis suggests and the paper recommends draws on the remaining outstanding contribution from that time: Walton’s.

Abstract

Background
We aimed to develop risk prediction models for new-onset home morning hypertension.

Methods
We followed up 978 participants without home hypertension in the general population of Ohasama, Japan (men: 30.1%, age: 53.3 years). The participants were divided into derivation (n = 489) and validation (n = 489) cohorts by their residential area. The C-statistics and calibration plots were assessed after the 5- or 10-year follow-up.

Results
In the derivation cohort, sex, age, body mass index, smoking, office systolic blood pressure (SBP), and home SBP at baseline were selected as significant risk factors for new-onset home hypertension (≥135/85 mm Hg or the initiation of antihypertensive treatment) using the Cox model. In the validation cohort, Harrell’s C-statistic for the 5-/10-year home hypertension was 0.7637 (0.7195–0.8100)/0.7308 (0.6932–0.7677), when we used the full model, which included the significant risk factors in the derivation cohort. The calibration test revealed good concordance between the observed and predicted 5-/10-year home hypertension probabilities (P ≥ 0.19); the regression slope of the observed probability on the predicted probability was 1.10/1.02, and the intercept was −0.04/0.06, respectively. A model without home SBP was also developed; for the 10-year home hypertension risk, the calibration test revealed a good concordance (P = 0.19) but Harrell’s C-statistic was 0.6689 (0.6266–0.7067).

Conclusions
The full model revealed good ability to predict the 5- and 10-year home morning hypertension risk. Although the model without home SBP is acceptable, the low C-statistic implies that home BP should be measured to predict home morning hypertension precisely.
MAGUS+eHMMs: improved multiple sequence alignment accuracy for fragmentary sequences
Authors: Shen Chengze , Zaharias Paul , Warnow Tandy 
Published: November 2021

Abstract

Summary
Multiple sequence alignment is an initial step in many bioinformatics pipelines, including phylogeny estimation, protein structure prediction and taxonomic identification of reads produced in amplicon or metagenomic datasets, etc. Yet, alignment estimation is challenging on datasets that exhibit substantial sequence length heterogeneity, and especially when the datasets have fragmentary sequences as a result of including reads or contigs generated by next-generation sequencing technologies. Here, we examine techniques that have been developed to improve alignment estimation when datasets contain substantial numbers of fragmentary sequences. We find that MAGUS, a recently developed MSA method, is fairly robust to fragmentary sequences under many conditions, and that using a two-stage approach where MAGUS is used to align selected ‘backbone sequences’ and the remaining sequences are added into the alignment using ensembles of Hidden Markov Models further improves alignment accuracy. The combination of MAGUS with the ensemble of eHMMs (i.e. MAGUS+eHMMs) clearly improves on UPP, the previous leading method for aligning datasets with high levels of fragmentation.

Availability and implementation
UPP is available on https://github.com/smirarab/sepp, and MAGUS is available on https://github.com/vlasmirnov/MAGUS. MAGUS+eHMMs can be performed by running MAGUS to obtain the backbone alignment, and then using the backbone alignment as an input to UPP.

Worldwide trends in oral anticoagulant use in patients with atrial fibrillation from 2010 to 2018: a systematic review and meta-analysis
Authors: Grymonprez Maxim , Simoens Cynthia , Steurbaut Stephane , De Backer Tine L , Lahousse Lies 
Published: November 2021

Abstract

Aims
Non-vitamin K antagonist oral anticoagulants (NOACs) are effective and safe alternatives compared with vitamin K antagonists (VKAs) for thromboembolic prevention in atrial fibrillation (AF), while antiplatelets are no longer recommended. However, to which extent NOAC introduction and guideline updates have increased OAC use in AF, is unclear. Therefore, worldwide trends in real-life prescribing of OACs, NOACs, VKAs, and antiplatelet monotherapy in AF patients were investigated.

Methods and results
Using PubMed and Embase, observational nationwide cohort studies on annual prevalent and/or incident OAC use in non-selected AF patients since 2010 were included. A meta-analysis of single proportions was performed. Twenty-one studies were included assessing prevalent and incident use among 9 758 637 and 197 483 OAC-eligible AF patients, respectively. Worldwide prevalence and incidence of OAC users increased from 0.42 [95% confidence interval (CI) 0.22–0.65] and 0.43 (95% CI 0.37–0.49) in 2010 to 0.78 (95% CI 0.77–0.78) and 0.75 (95% CI 0.74–0.76) in 2018, respectively. Prevalent and incident NOAC users increased globally from 0 in 2010 to 0.45 (95% CI 0.45–0.46) and 0.68 (95% CI 0.67–0.69) in 2018, respectively, whereas prevalent and incident VKA use decreased from 0.42 (95% CI 0.22–0.65) and 0.42 (95% CI 0.36–0.49) in 2010 to 0.32 (95% CI 0.32–0.32) and 0.06 (95% CI 0.06–0.07) in 2018, respectively. Prevalent antiplatelet monotherapy use decreased from 0.37 (95% CI 0.32–0.42) in 2010 to 0.09 (95% CI 0.09–0.10) in 2018.

Conclusion
The proportion of OAC users worldwide almost doubled following NOAC introduction. As one-quarter of OAC-eligible AF subjects were not anticoagulated and 9% were only treated with antiplatelets in 2018, there is still room for improvement.
