Published: February 2022

Abstract
Jakarta has an essential function for Indonesia, apart from being the capital city of the country, Jakarta is also the center of the nation’s economy. However, the problem of flooding that occurs every year causes enormous material and immaterial losses. One of the metropolitan areas that is often hit by floods is Bendungan Hilir Village. This village is the meeting point between the Ciliwung River and the Krukut River. One of the causes of flooding is when the water level in both rivers is high, the water from the Krukut River cannot flow, so it overflows into the surrounding area. For this reason, this study will analyze the level of flood hazard and the effect of normalization of the Krukut River. The analysis was performed using the HEC-RAS, combining 1D and 2D modeling. In the upstream part, the Krukut watershed flood hydrograph is applied for a return period of 25 years with a peak discharge of 169 m3/s, and the normal depth will be used as the downstream boundary. The modeling is carried out in two conditions, they are the existing channel and the channel after normalization. Based on the model results it is found that normalization could reduce the flood hazard of Krukut river around 75%.

Published: February 2022

Abstract
Wall Cracks in a slope area with high landslide risk is very common. Triggered by small horizontal land movement, relative movement of walls separated by the crack line to create wider crack can occur. In the present work, an early warning system for landslide utilizing such movement is presented. For this purpose, a bar is connected to the displacement sensor. Sensor is fixed to one side of wall at either before or after crack line. The bar from this sensor is fixed to the other side of the wall at the direction perpendicular to the crack. With this configuration, small movement of one part of wall (before or after crack line) activate the sensor. In this paper, two displacement sensors are used, i.e., displacement sensor based on slide resistor and fiber sensor. In the present work, warning is given in the form of sound characterized the increase of frequency as the width of crack increase.

Published: February 2022

Abstract
The most commonly used baseflow separation graphics method is the recursive digital filter. Choosing an RDF graphic filter method to estimate the base stream requires a sure accuracy. The application of the RDF graphics method on small island watersheds must take into account the unique hydrological conditions of small island watersheds with a small area of rain catch so that the RDF method approach can be applied. This research aims to analyze graphic methods for the hydrological characteristics of the small island watershed of the Ambon City of Maluku Province. The research method uses five RDF methods: one parameter algorithm, two-parameter algorithm, RDF Lyne & Holick, RDF Chapman, and RDF Eckhard. The results showed that the appropriate filter parameter value for small island watersheds was based on optimal parameters for assessing accuracy. The five RDFs showed that Eckhardt’s filters performed better than one parameter algorithm, two parameters algorithm, Lyne and Hollick algorithm, and Champman algorithm, on a more extensive range of conditions. The optimal value of the filter parameters is relatively uniform for all five filter methods depending on the characteristics of the watershed and somewhat similar hydrological inputs.

Authors: Pereira J , Mahojwala G , Paripurno ET , Effendi MI 
Published: February 2022

Abstract
The cement industry investment in Baucau Regency is agreed to be the key to economic growth, creating new jobs, and reducing poverty. To support this investment in the cement industry sector, the government of Timor Leste issued Government Resolution no. 14/2016 regarding the Special Investment Agreement submitted by the Company TL Cement, Lda. Baucau Regency area has a good stretch of karst for the supply of the main raw material for cement production, thus chosen as an investment location. Tirilolo village as well as the surrounding community, where they plan to establish a limestone factory and mine is planned – will receive both benefits and risks from the investment planning. This study uses a mixed-method with a survey approach, interviews, and questionnaires, with socio-economic risk assessment at the local level in the cement industry investment plan sector. This study uses secondary data analysis and field observations. The data obtained will be analyzed descriptively and using a scoring technique on each indicator. Some of the research results obtained indicate a basic vulnerability, that the population density in Tirilolo Village is 52 people/ha, with female household heads 5%, people with disabilities 7%, vulnerable age population 26%. In the education sector, 68.75% of the population did not go to school, while only 17% graduated from elementary school, 5.2% graduated from junior high school, and 8.3% graduated from high school. The average community income is less than $100 per month. The results of structured interviews and focus group discussions show that even though factories and mines carry risks, people look forward to jobs that will emerge to make changes in their lives.

Published: February 2022

AbstractThe Indonesian archipelago lies at triple junction between the world’s tectonic plates that have many natural disasters. Furthermore, Indonesia lies accross the equator which result in a tropical climate (dry and rainy seasons). During the rainy season, rainfall often triggers landslides. Landslides can be identified by the material type (soil, rock, or debris) and movement (slide, fall, flow, or combination). Landslide-prone areas can be influenced by lithology (rock type and weathering), slope (geomorphology), seismic vibrations (tectonic aspects), and human activities. In order to anticipate landslides, both structural and non-structural mitigation are required. Non-structural mitigation is required to determine the condition of rainfall, and the type of landslides. RAFLEWS (Rainfall Apparatus for Landslide Early Warning System) design model is a part of non-structural mitigation. Non-structural mitigation is also required to anticipate the possibility of landslides. Proposal of Hexa Helix participatory concept is a part for early warning system which will be useful in supporting non-structural mitigation. Hexa Helix consists of six participant elements, namely: Academia, Government, Society, Industry, Mass Media, and Laws/Regulations/Legislations. Combination of RAFLEWS model and Hexa Helix concept is expected to be influential in dealing with landslide disasters in the future.

Published: February 2022

Abstract
One of the most water-related disasters is flooding induced by heavy rain. According to several model experiments and an analysis of historical data, such natural disasters will become more common in the future. In recent years, torrential rain and flooding have caused significant damage to agricultural land, homes, and human life in numerous Japanese towns. We used the Hitoyoshi City in Kumamoto Prefecture, Japan, as a case study for the area’s flood event in July 2020. This study uses machine learning to study spatial analysis of the city of Hitoyoshi after the 2020 flood disaster. Assessments such as flood hazards, exposure, and susceptibility are critical components of total flood risk assessment. In addition, this study also uses several driving factors for mapping the scenario to the evacuation center, how the impact of flooding on the residential environment, and changes to land use in the Hitoyoshi area. For land-use planners, estimating the quickly flooded region using distinct land use profiles is quite important. It aids in the analysis of flood losses and the allocation of resources for recovery and restoration.

Published: February 2022

Abstract
Here we report the 3D bioprinting of a simplified model of the heart, similar to that observed in embryonic development, where the heart is a linear tube that pumps blood and nutrients to the growing embryo. To this end, we engineered a bioinspired model of the human heart tube using freeform reversible of embedding of suspended hydrogels 3D bioprinting. The 3D bioprinted heart tubes were cellularized using human stem cell-derived cardiomyocytes and cardiac fibroblasts and formed patent, perfusable constructs. Synchronous contractions were achieved ∼3–4 days after fabrication and were maintained for up to a month. Immunofluorescent staining confirmed large, interconnected networks of sarcomeric alpha actinin-positive cardiomyocytes. Electrophysiology was assessed using calcium imaging and demonstrated anisotropic calcium wave propagation along the heart tube with a conduction velocity of ∼5 cm s−1. Contractility and function was demonstrated by tracking the movement of fluorescent beads within the lumen to estimate fluid displacement and bead velocity. These results establish the feasibility of creating a 3D bioprinted human heart tube and serve as an initial step towards engineering more complex heart muscle structures.
Device level reversible potassium intercalation into bilayer graphene
Authors: Yang Sheng , Fecher Sven , Wang Qixing , Kühne Matthias , Smet Jurgen H 
Published: February 2022

Abstract
Electrochemical intercalation and storage of alkali metal ions into the graphite interlayer space is a key ingredient for commercial rechargeable ion batteries. While this has been exceptionally fruitful for lithium, the use of other more abundant chemical species such as potassium has fallen behind due to their less favorable ionic radius and host–guest interactions. Here, we deploy a device level on-chip cell architecture to study the reversible intercalation of potassium into the single van der Waals gallery of a graphene bilayer at room temperature and monitor in a time-dependent manner the electronic properties of the graphene bilayer during the insertion and extraction processes. The potassium diffusion is highly reversible and a charge transfer up to about 2.5 × 1013 cm−2 is achieved. The diffusion coefficient well exceeds 10−7 cm2 s−1 at room temperature, an order of magnitude larger than previously reported values in graphite and other compounds.
Photon detection probability prediction using one-dimensional generative neural network
Authors: Mu Wei , Himmel Alexander I , Ramson Bryan 
Published: February 2022

Abstract
Photon detection is important for liquid argon detectors for direct dark matter searches or neutrino property measurements. Precise simulation of photon transport is widely used to understand the probability of photon detection in liquid argon detectors. Traditional photon transport simulation, which tracks every photon using the Geant4 simulation toolkit, is a major computational challenge for kilo-tonne-scale liquid argon detectors and GeV-level energy depositions. In this work, we propose a one-dimensional generative model which efficiently generates features using an

-layer. This model bypasses photon transport simulation and predicts the number of photons detected by particular photon detectors at the same level of detail as the Geant4 simulation. The application to simulating photon detection systems in kilo-tonne-scale liquid argon detectors demonstrates this novel generative model is able to reproduce Geant4 simulation with good accuracy and 20 to 50 times faster. This generative model can be used to quickly predict photon detection probability in huge liquid argon detectors like ProtoDUNE or DUNE.
Why are women with polycystic ovary syndrome obese?
Authors: Barber T M 
Published: February 2022

Abstract

Introduction
Polycystic ovary syndrome (PCOS) is a common condition characterized by reproductive, hyperandrogenic and dysmetabolic features, and often becomes clinically manifest during adolescence, particularly with weight-gain.

Sources of data
Pubmed search.

Areas of agreement
PCOS is heritable and closely associates with obesity (based on data from both epidemiological and genetic studies). Furthermore, insulin resistance forms a central cornerstone of the pathogenesis of PCOS and mediates a close association between obesity and the severity of the phenotypic features of PCOS.

Areas of controversy
Our understanding of the pathogenesis of PCOS remains incomplete, especially regarding its missing heritability (with only a small fraction having been identified from the genome-wide association studies reported to date), and its developmental origins.

Growing points
A challenge for the future is to explore a role for epigenetic modifications in the development of PCOS, and implications for the in utero environment and novel therapeutic opportunities.
Graph space: using both geometric and probabilistic structure to evaluate statistical graph models
Authors: Duvivier Louis , Cazabet Rémy , Robardet Céline 
Published: February 2022

Abstract
Statistical graph models aim at representing graphs as random realization among a set of possible graphs. To evaluate the quality of a model $M$ with respect to an observed network $G$, most statistical model selection methods rely on the probability that $G$ was generated by $M$, which is computed based on the entropy of the associated microcanonical ensemble. In this article, we introduce another possible definition of the quality of fit of a model based on the edit distance expected value. We show that adding a geometric structure to the microcanonical ensemble induces an alternative perspective which may lead to select models which could potentially generate more different graphs, but whose structure is closer to the observed network. Finally, we introduce a statistical hypothesis testing methodology based on this distance to evaluate the relevance of a candidate model with respect to an observed graph.

Authors: Giblin Gerard T , Cuddy Sarah A M , González-López Esther , Sewell Alanna , Murphy Amanda , Dorbala Sharmila , Falk Rodney H 
Published: February 2022

Abstract

Aims
In patients with transthyretin amyloid cardiomyopathy (ATTR-CM), the effect of tafamidis on myocardial function using serial speckle tracking echocardiography has not been reported. The purpose of this study was to describe the natural history of myocardial function in untreated ATTR-CM and determine the effect of tafamidis on myocardial functional parameters over 12 months of treatment.

Methods and results
A total of 45 subjects with ATTR-CM were retrospectively studied: 23 treated with tafamidis and 22 untreated. Two-dimensional speckle tracking echocardiography was analysed at baseline and 1 year. Serial longitudinal, circumferential, and radial strain, twist, torsion, and myocardial work were measured. Over 1 year, absolute global longitudinal strain (GLS) deteriorated more in the untreated group by a median of 1.1% [inter-quartile range (IQR) 0.95] compared with 0.3% (IQR 1) in the tafamidis group (P = 0.02). Myocardial work index and efficiency also deteriorated to a greater degree: 142.5 mmHg% (IQR 197) and 4% (IQR 8), respectively, in the untreated group compared with 61.5 mmHg% (IQR 210) and 1% (IQR 7) in the tafamidis group (P = 0.04). There were no significant between group differences in left ventricular ejection fraction (LVEF), tissue Doppler velocities, circumferential or radial strain, LV twist or torsion at 1 year. The stabilization effect of tafamidis on myocardial function at 1 year did not differ according to baseline GLS, LVEF, or National Amyloidosis Centre disease stage.

Conclusions
In ATTR-CM, tafamidis resulted in a lesser deterioration in GLS, myocardial work index, and efficiency over a 12-month period compared with a cohort not treated with tafamidis.

Published: February 2022

Abstract

OBJECTIVES
The oncological efficacy of minimally invasive thymectomy for thymic carcinoma is not well characterized. We compared overall survival and short-term outcomes between open and minimally invasive surgical (video-assisted thoracoscopic and robotic) approaches using the National Cancer Database.

METHODS
Perioperative outcomes and overall survival of patients who underwent open versus minimally invasive thymectomy for Masaoka stage I–III thymic carcinoma from 2010 to 2015 in the National Cancer Database were evaluated using propensity score-matched analysis and multivariable Cox proportional hazards modelling. Outcomes by surgical approach were assessed using an intent-to-treat analysis.

RESULTS
Of the 216 thymectomies that were evaluated, 43 (20%) were performed with minimally invasive techniques (22 video-assisted thoracoscopic and 21 robotic). The minimally invasive approach was associated with a shorter median length of stay when compared to the open approach (3 vs 5 days, P &lt; 0.001). In the propensity score-matched analysis of 30 open and 30 minimally invasive thymectomies, the minimally invasive group did not differ significantly in median length of stay (3 vs 4.5 days, P = 0.27), 30-day readmission (P = 0.13), 30-day mortality (P = 0.60), 90-day mortality (P = 0.60), margin positivity (P = 0.39) and 5-year survival (78.6% vs 54.6%, P = 0.15) when compared to the open group.

CONCLUSIONS
In this national analysis, minimally invasive thymectomy for stage I–III thymic carcinoma was found to have no significant differences in short-term outcomes and overall survival when compared to open thymectomy.

Abstract

OBJECTIVES
The incidence of postoperative complications is relatively high in smokers. Although 4-week smoking cessation before surgery is generally recommended, it has not been sufficiently studied in lung cancer surgery. This study investigated whether smoking cessation for a short period of time significantly reduced complications after lung cancer surgery.

METHODS
This was a retrospective, observational study that investigated the relationship between the smoking cessation period and the incidence of complications in lung cancer surgery. Patients who underwent curative-intent surgery for lung cancer at our institution between January 2014 and December 2017 were included. The smokers were classified into the following 4 categories of smoking cessation period before surgery: current (&lt;4 weeks), recent (4 weeks to 12 months), distant (12 months to 5 years) and ex-smokers (&gt;5 years).

RESULTS
A total of 911 patients were included in this study. The incidence of pulmonary complications was 5 times higher in the smoker group than in the never smoker group (12.9% vs 2.5%, P &lt; 0.001). On multivariable analysis in both models, the odds ratio for complications was significantly higher in distant smokers than in recent smokers and never smokers. Across all models, low lung function significantly predicted the development of postoperative complications.

CONCLUSIONS
The evidence-based smoking cessation duration that reduces the incidence of complications after thoracic surgery remains unclear. The incidence of postoperative complications was more strongly affected by low pulmonary function than by the duration of preoperative smoking cessation. For patients with marginal indications for surgery, postponing surgery to accommodate a smoking cessation period seemed unnecessary.
