The Effect Of Rainfall On The Detection Of Standing Water On Runway
Authors: Firdiyan N , Muntini M S 
Published: July 2021

Abstract
The need for knowledge about the presence of water on the runway is very urgent to be a concern. The existence of puddles on the runway can cause problems for aircraft, such as slip due to low friction. According to The National Transportation Safety Committee (NTSC), 32% of flight accidents in Indonesia were caused by a slippery runway. The existence of water on the runway cannot be separate from the role of rain as a source of water that inundates the runway. To be able to determine the potential for inundation, sensors are needed to measure three parameters; rainfall, rain intensity, and standing water detection. By placing a rainfall sensor and a standing water detector, it can detect the effect of rainfall in detecting standing water on the runway. This is shown in the rainfall test as a support for a standing water detector on the runway where the average wind speed of 5.14 m/s during the test on the runway. Through the analysis of the measurement of detectors to present the data is greatly influenced by the several conditions of rainfall, factor of rainfall and rainfall type.

Published: July 2021

Abstract
Acoustic parameters of a room affect the information received by listeners. Several acoustic parameters need to be met so that the information conveyed in a room can be clearly understood by listeners. The acoustic parameters include background noise, SPL distribution, reverberation time (RT), Clarity (C80, C50), and Definition (D50). This paper discusses the evaluation of acoustics parameters in the ITS science tower auditorium. The auditorium has a square shape with a volume of 3,387 m3. The evaluation was carried out using the impulse response method in an unoccupied auditorium without a chair. Based on the measurement results when unoccupied without a chair, It was found 27-31.6 dB, 64.5-76.5 dBA, 3.3-4 s, -5 to 1 dB and 8-40% for background noise, SPL, RT, C80 and D50 at the frequency of 1000 Hz, respectively. This shows that the auditorium does not yet fulfill a multi-function room. Consequently it is necessary to improve acoustic conditions through simulations with the addition of chairs, people, and loudspeakers. The simulation results in the auditorium obtained SPL of 78.32-94.2 dBA, RT of 0.95s, and an average of C80 of 4.01 dB, which indicates that the auditorium is closer to a multi-function room than before.

Published: July 2021

Abstract
The Regency of Pangandaran is located on the southern side of West Java, surrounded by local faults, and close to the Indo-Australia and Eurasian subduction zone, causing the area to feel the earthquake’s impact often. Tasikmalaya Earthquake M 7.3, on September 2, 2009, was felt strong and has caused damage in this area. Therefore, mitigation efforts are critical to reducing the earthquake impact. This study aims to determine the classification of soil types in the southern Pangandaran based on 1D Vs up to 30 m depth (Vs30) measured by the Multichannel Analysis of Surface Wave (MASW) method. The study used the SNI 1726-2012 as the categorization of soil types based on Vs30. To clarify, the Vs profile made the cross-section from west to east part in 2D. The results show that hard and medium soils dominate the research area with Vs30 values between 210 - 627 m/s that make the area relatively safe from the potential of strong earthquake shocks. However, the southern part of Cijulang, Parigi, and Pangandaran districts have medium soil types that are relatively thick. Those parts may indicate the potential for stronger earthquake shocks.

Authors: Syahid A , Yuniati A 
Published: July 2021

Abstract
Simulation of neuron spiking activity models has been carried out using the Euler method. This study aims to simulate spiking activity in a neuron model. The neuron model used is the Hodgkin-Huxley neuron model, Integrate and Fire neuron model, Wilson neuron model, and Izhikevich neuron model. The research was conducted by implementing the mathematical equations of each neuron model used and then recording the membrane potential changes from time to time using the Euler method in MATLAB. The different forms of spiking activity were done by varying the variable’s value in each mathematical equation of a neuron model that describes the processing of action potentials (spikes) influenced by ion channel activity. The results showed that the Integrate and Fire neuron models produce regular spiking (RS), Hodgkin-Huxley neuron models have regular spiking (RS) forms, Wilson neuron models produce regular spiking (RS), fast-spiking (FS), and intrinsic bursting (IB), Izhikevich neuron model produces regular spiking (RS), fast-spiking (FS), intrinsic bursting (IB), chattering neurons (CH), and low threshold spiking (LTS). The complexity of the variables used and the spiking activity generated by each neuron model can provide an overview of computational efficiency and proximity to actual biological neurons.
Fast-Forward of Local-Phased-Regularized Spinor in Massless 2+1-Dimensions Adiabatic Dirac Dynamics
Authors: Sugihakim Ryan , Setiawan Iwan , Gunara Bobby Eka 
Published: July 2021

Abstract
We discuss a method of controlling Dirac dynamics in (2+1)-dimensions using adiabatic fast-forward method proposed by Masuda-Nakamura. Due to infinitely large amount of time of adiabaticity, we have to use an infinitely large scaling factor to shorten the time interval. Thus, we need a regularization to remove this infinity. Our strategy is analogue to adiabatic fast-forward of Schrodinger equation. That is using an auxiliary Hamiltonian but now we use two phase factors applied to the components of spinor. We applied to a case where a system is controlled by uniform magnetic field.

Published: July 2021

Abstract
To investigate the microstructure evolution and mechanical properties of materials treated by friction stir processing process at various the shoulder sizes and rotating speeds of the tool, a series of friction stir processing experiments were carried out on the AZ31 magnesium alloy with thickness of 4mm by using tool shoulder sizes of 12, 16 and 18mm, and two kinds of rotating speeds of 750r/min and 1500r/min with a constant feed speed of 60mm/min were supplied. Based on the analysis of morphology and mechanical properties of the materials, results demonstrated that reduction of tool shoulder size and rotating speed would contribute to more remarkable the grain refinement effect and affect the strong texture and extreme density strength of the material, leading to higher microhardness. However, lower mechanical properties of yield strength and tensile strength were obtained at these parameters owing to the existence of internal organization defect and stronger defect sensitivity of it. All of the findings would further deepen the understanding of the technique of friction stir processing and contribute to the application of AZ31 magnesium alloy treated by friction stir processing.

Published: July 2021

AbstractIn order to heighten their near infrared light-sensitive characteristics, lead phthalocyanine (PbPc) phototransistors were prepared by vacuum evaporation at various substrate temperatures (Ts) of 60°C, 100°C, 140°C and 180°C. The crystalline texture, absorption spectrum and surface morphology of PbPc films were measured. The light-sensitive characteristic measurement results indicated that the photoresponsivity (R) and specific detectivity (D*) of the devices first rise and dwindle asTsgrows and a best performance is gained atTs= 100°C. Research on the correlation between substrate-temperature-dependent film properties and device performance showed that the crystal texture, interconnection of grains, light absorption and carrier mobility of PbPc films could be varied by substrate heating, and thereby causing the variations in the device performance forRandD*. Moreover, a model semi-quantitatively describing the variation of photocurrent with optical absorption coefficient and carrier mobility was set up, and some numerical calculations were made base on the model presented.

Published: July 2021

Abstract
To enhance and lengthen the anti-aging performance and service lifetime of bitumen, 3-methacryloxypropyltrimethoxysilane grafted layered double hydroxides (LDHs) was synthesized and exploited to modify bitumen. The contact angle of organic LDHs (OLDHs) increased from 17.8° to 39.2°, the hydrophilic of OLDHs obviously decreased in comparison with LDHs, which contributed to disperse more uniformly in bitumen. Furthermore, the stability of LDHs in bitumen became better after 3-methacryloxypropyltrimethoxysilane modification. After aging, the penetration and ductility of bitumen markedly declined, correspondingly, the softening point and viscosity remarkably rose, the physical performance of bitumen were deteriorated seriously. The addition of LDHs and OLDHs could restrain the properties degradation after aging, enhance the anti-aging of bitumen, and OLDHs exhibited much more excellent, because of the outstanding stability in bitumen.

Authors: Chen Jonlin , Chow Amanda , Fadavi Darya , Long Chao , Sun Alexander H , Cooney Carisa M , Broderick Kristen P 
Published: July 2021

Abstract

Background
The COVID-19 pandemic has led to the widespread adoption of video calling. A parallel growth in aesthetic surgery demand has been documented.

Objectives
The authors sought to identify associations between video call engagement and aesthetic surgery attitudes.

Methods
We distributed a cross-sectional survey via Amazon Mechanical Turk in November 2020. Respondents were asked to report their time spent video calling, video calling applications and features (eg, virtual backgrounds) they utilized, and aesthetic surgery attitudes employing the 15-item Acceptance of Cosmetic Surgery Scale (ACSS; higher scores indicate greater acceptance). ACSS scores were compared between video call users and non-users employing t tests. Pearson’s correlation coefficient was employed to quantify associations between ACSS scores and time spent on calls and multivariable analysis to estimate associations between video call engagement and ACSS scores.

Results
A total of 295 respondents (mean age, 37.6 years; 49.5% female) completed the survey. Across all video call applications surveyed, video call users had higher ACSS scores than non-users. Increased time respondents spent looking at their own face on video call was moderately associated with higher ACSS scores (r = 0.48, P &lt; 0.01), whereas time spent looking at another person’s face was not associated with a change in ACSS scores (r = 0.09, P = 0.11). Increased video call utilization was associated with higher ACSS scores.

Conclusions
Increased video calling utilization is associated with increased acceptance of aesthetic surgery. Although the clinical significance of ACSS scores can be better elucidated, plastic surgeons should consider the effects of video calling on patient motivations for aesthetic surgery in the COVID-19 era.
Crucial role of the intracellular α-glucosidase MalT in the activation of the transcription factor AmyR essential for amylolytic gene expression in Aspergillus oryzae
Authors: Ichikawa Takanori , Tanaka Mizuki , Watanabe Takayasu , Zhan Sitong , Watanabe Akira , Shintani Takahiro , Gomi Katsuya 
Published: July 2021

ABSTRACT
We examined the role of the intracellular α-glucosidase gene malT, which is part of the maltose-utilizing cluster (MAL cluster) together with malR and malP, in amylolytic gene expression in Aspergillus oryzae. malT disruption severely affected fungal growth on medium containing maltose or starch. Furthermore, the transcription level of the α-amylase gene was significantly reduced by malT disruption. Given that the transcription factor AmyR responsible for amylolytic gene expression is activated by isomaltose converted from maltose incorporated into the cells, MalT may have transglycosylation activity that converts maltose to isomaltose. Indeed, transglycosylated products such as isomaltose/maltotriose and panose were generated from the substrate maltose by MalT purified from a malT-overexpressing strain. The results of this study, taken together, suggests that MalT plays a pivotal role in AmyR activation via its transglycosylation activity that converts maltose to the physiological inducer isomaltose.

Summary
Sarcopenia, which involves two important aspects, namely skeletal muscle loss and decreased physical function, was suggested as a poor prognostic factor in esophageal cancer surgery. The purpose of this study was to clarify the perioperative change in daily physical activity and propose effective preventive strategies. We prospectively enrolled patients with esophageal cancer who were scheduled to undergo radical esophagectomy. Their daily physical activities were recorded using an accelerometer before surgery, immediately after discharge, and 6 months after surgery. The relationships of physical activity level and the perioperative factors, especially skeletal muscle change, with the risk factors of low daily activity level were investigated. The data of 20/28 enrolled patients were analyzed. The mean activity level of the 20 patients decreased after discharge and subsequently recovered on postoperative month 6. The percentage of activity levels &gt;1.5 metabolic equivalents/day after discharge significantly correlated to the change rate in total muscle cross-sectional area from baseline to POM 6 (r = 0.452, P = 0.045). In a stepwise multiple regression analysis, age, neoadjuvant chemotherapy, and anastomotic leakage were identified as negative associated factors of activity time at &gt;1.5 metabolic equivalents at postoperative month 6. Activity level immediately after discharge was significantly associated with skeletal muscle loss at postoperative month 6 in patients with esophageal cancer who underwent esophagectomy. Elderly patients and patients who received neoadjuvant chemotherapy and had an anastomotic leakage might require intensive prevention. Prospective interventions aimed at increasing daily activity can prevent sarcopenia.

Published: July 2021

Abstract

Background
Studies of adults with Crohn’s disease (CD) suggest that poor mental health precedes worsening disease activity. We evaluated whether depression and/or anxiety forecast worsening pediatric CD disease activity.

Methods
Through the Inflammatory Bowel Disease Partners Kids & Teens internet-based cohort, children with CD age 9 to 17 completed Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric measures and the short Crohn’s disease activity index (sCDAI). Using general linear models, we examined how baseline PROMIS Pediatric anxiety and depressive symptom scores independently associate with subsequent sCDAI scores (average survey interval 6.4 months). Models included baseline PROMIS Pediatric anxiety and depressive symptoms scores, baseline sCDAI, sex, age, parental education, race/ethnicity, and prior IBD-related surgery. We performed a post hoc subanalysis of children in baseline remission (sCDAI &lt;150) with otherwise identical models.

Results
We analyzed 159 children with CD (mean age 14 years, 45% female, 84% in baseline remission). We found no association between baseline PROMIS Pediatric anxiety score and subsequent sCDAI (change in sCDAI for 3-point change in PROMIS Pediatric −0.89; 95% CI −4.81 to 3.03). Baseline PROMIS Pediatric depressive symptoms score was not associated with future sCDAI (change in sCDAI for 3-point change in PROMIS Pediatric &lt;0.01; 95% CI −4.54 to 4.53). In a subanalysis of patients in remission at baseline, the lack of association remained.

Conclusion
We found that neither anxiety nor depressive symptoms associate with subsequent disease activity in pediatric CD. These findings contrast with adult IBD studies, thus underschoring the unique pathophysiology, natural history, and outcomes of pediatric CD.

Authors: Weissman Simcha , Systrom Hannah K , Aziz Muhammad , El-Dallal Mohammed , Lee-Smith Wade , Sciarra Michael , Feuerstein Joseph D 
Published: July 2021

Abstract

Background
Owing to the increased risk of colorectal cancer (CRC) in patients with inflammatory bowel disease (IBD), numerous societies developed preventative guidelines. We aimed to assess the overall quality of CRC prevention guidelines in IBD.

Methods
A systematic search was performed in multiple databases to identify all guidelines pertaining to CRC prevention in IBD in September 2020. All guidelines were reviewed for conflicts of interest (COIs)/funding, recommendation quality/strength, external guideline review, use of patient representation, and plans for update—as per Institute of Medicine standards. In addition, recommendations were compared amongst societies.

Results
One hundred forty-nine recommendations from 14 different guidelines/societies were included. Not all guidelines provided recommendations on key elements surrounding (1) screening initiation and surveillance, (2) screening modality, (3) pharmacological chemoprevention, (4) dysplasia management and follow-up, and (5) molecular marker use. Only 71% of guidelines disclosed COIs, 43% reported industry funding, 14% were externally reviewed, 7% included patient representation, and 36% had plans for update. Of the total recommendations, 7.4%, 23.5%, and 69.1% were based on high,- moderate-, and low-quality evidence, respectively. Additionally, 20.1% of recommendations were strong, 14.1%, were weak/conditional, and 65.8% did not provide a strength. The proportion of high-quality evidence (P = 0.34) and strong recommendations (P = 0.57) did not significantly differ across societies.

Conclusions
Many guidelines do not provide recommendations on key aspects of CRC prevention in IBD. Over 90% of recommendations are based on low- to moderate-quality evidence; therefore, further studies on CRC prevention in IBD are needed to improve the overall quality of evidence.
Identifying possible drivers of the abrupt and persistent delay in capelin spawning timing following the 1991 stock collapse in Newfoundland, Canada
Authors: Murphy Hannah M , Adamack Aaron T , Cyr Frédéric 
Published: July 2021

Abstract
Spawning timing in fish is generally cyclical in temperate regions in order to increase the probability of matching larval occurrence with ideal environmental conditions. The capelin stock in Northwest Atlantic Fisheries Organization Divisions 2J3KL collapsed in 1990–1991 and has not recovered. This collapse was concomitant with collapses in groundfish stocks and cold oceanographic conditions. Using citizen science data, newspaper archives, grey and primary literature, and monitoring data, a century of capelin beach spawning times were compiled. Capelin beach spawning has been persistently 3 weeks later since the stock collapse. To identify potential predictors of capelin spawning timing, an exploratory analysis was conducted using environmental and biological variables and a period factor that categorized a year as either pre-collapse (1990 and earlier) or post-collapse (post-1990) in a step-wise multiple regression model. Spawning timing was predicted to be delayed in the post-collapse period when there were negative anomalies in the Newfoundland and Labrador Climate Index and summer (June–August) North Atlantic Oscillation, and when there was a decrease in mean length of the spawning population. The production of weak year-classes is predicted when spawning is delayed, suggesting that late spawning is severely inhibiting the recovery of the stock.

Published: July 2021

Abstract OBJECTIVESThis study investigates whether the surgical correction of chest deformity is associated with the growth of the lung parenchyma after surgery for pectus excavatum.METHODSTen patients with pectus excavatum who were treated by the Nuss procedure were examined. The preoperative and postoperative computed tomography (2.5 ± 1.2 years after surgery) scans were performed, and the Haller index, lung volume and lung density were analyzed using a three-dimensional image analysis system (SYNAPSE VINCENT, Fujifilm, Japan). The radiological lung weight was calculated as follows: lung volume (ml) × lung density (g/ml).RESULTSThe average age of the 10 patients (men 8; women 2) was 13.8 years (range: 6–26 years). The Haller index was significantly improved from the preoperative value of 5.18 ± 2.20 to the postoperative value of 3.68 ± 1.38 (P = 0.0025). Both the lung volume and weight had significantly increased by 107.1 ± 19.6% and 121.6 ± 11.3%, respectively, after surgery.CONCLUSIONSA significant increase in the weight of the lung after surgical correction suggests that the growth of the lung parenchyma is associated with the correction of chest deformity in younger patients with pectus excavatum.
