Modeling the interinfluence of fertilizer-induced NH3 emission, nitrogen deposition, and aerosol radiative effects using modified CESM2
Authors: Fung Ka Ming , Val Martin Maria , Tai Amos P. K.
Published: March 2021

Abstract. Global ammonia (NH3) emission is expected to continue to rise due to intensified fertilization for growing food to satisfy the increasing demand worldwide. Previous studies focused mainly on estimating the land-to-atmosphere NH3 injection but seldom addressed the other side of the bidirectional nitrogen exchange – deposition. Ignoring this significant input source of soil mineral nitrogen may lead to an underestimation of NH3 emissions from natural sources. Here, we used an Earth system model to quantify NH3-induced changes in atmospheric composition and the consequent impacts on the Earth's radiative budget and biosphere, as well as the impacts of deposition on NH3 emissions from the land surface. We implemented a new scheme into the Community Land Model version 5 (CLM5) of the Community Earth System Model version 2 (CESM2) to estimate the volatilization of ammonium salt (NH4+) associated with synthetical fertilizers into gaseous NH3. We further parameterized the amount of emitted NH3 captured in the plant canopy to derive a more accurate quantity of NH3 that escapes to the atmosphere. Our modified CLM5 estimated that 11 Tg-N yr−1 of global NH3 emission is attributable to synthetic fertilizers. Interactively coupling terrestrial NH3 emissions to atmospheric chemistry simulations by the Community Atmospheric Model version 4 with chemistry (CAM4-chem), we found that such emissions favor the formation and deposition of NH4+ aerosol, which in turn disrupts the aerosol radiative effect and enhances soil NH3 volatilization in regions downwind of fertilized croplands. Our fully-coupled simulations showed that global-total NH3 emission is enhanced by nitrogen deposition by 2.4 Tg-N yr−1, when compared to the baseline case with 2000-level fertilization but without deposition- induced enhancements. In synergy with observations and emission inventories, our work provides a useful tool for stakeholders to evaluate the intertwined relations between agricultural trends, fertilize use, NH3 emission, atmospheric aerosols, and climate, so as to derive optimal strategies for securing both food production and environmental sustainability.

Abstract. Land evaporation (ET) plays a crucial role in hydrological and energy cycle. However, the widely used numerical products are still subject to great uncertainties due to imperfect model parameterizations and forcing data. Lack of available observed data has further complicated the estimation. Hence, there is an urgency to define the global benchmark land ET for climate-induced hydrology and energy change. In this study, we have used the coefficient of variation (CV) and carefully selected merging regions with high consistency of multiple data sets. Reliability Ensemble Averaging (REA) method has been used to generate a long-term (1980–2017) daily ET product with a spatial resolution of 0.25 degree by merging the selected three data sets, ERA5, GLDAS2 and MERRA2. GLEAM3.2a and flux tower observation data have been selected as the data for reference and evaluation, respectively. The results showed that the merged product performed well under a variety of vegetation cover conditions as the weights were distributed across the east-west direction banding manner, with greater differences near the equator. The merged product also captured well the trend of land evaporation over different areas, showing the significant decreasing trend in Amazon plain in South America and Congo Basin in central Africa, and the increasing trend in the east of North America, west of Europe, south of Asia and north of Oceania. In addition to model performance, REA method also successfully worked for the model convergence showing as an outstanding reference for data merging of other variables.

Abstract. Soil moisture (SM) datasets are critical to understanding the global water, energy, and biogeochemical cycles and benefit extensive societal applications. However, individual sources of SM data (e.g., in situ and satellite observations, reanalysis, offline land surface model simulations, Earth system model simulations) have source-specific limitations and biases related to the spatiotemporal continuity, resolutions, and modeling/retrieval assumptions. Here, we developed seven global, gap-free, long-term (1970–2016), multi-layer (0–10, 10–30, 30–50, and 50–100 cm) SM products at monthly 0.5° resolution (available at https://doi.org/10.6084/m9.figshare.13661312.v1) by synthesizing a wide range of SM datasets using three statistical methods (unweighted averaging, optimal linear combination, and emergent constraint). The merged products outperformed their source datasets when evaluated with in situ observations and the latest gridded datasets that did not enter merging because of insufficient spatial, temporal, or soil layer coverage. Assessed against in situ observations, the global mean bias of the synthesized SM data ranged from −0.044 to 0.033 m3/m3, root mean squared error from 0.076 to 0.104 m3/m3, and Pearson correlation from 0.35 to 0.67. The merged SM datasets also showed the ability to capture historical large-scale drought events and physically plausible global sensitivities to observed meteorological factors. Three of the new SM products, produced by applying any of the three merging methods onto the source datasets excluding the Earth system models, were finally recommended for future applications because of their better performances than the Earth system model–dependent merged estimates. Despite uncertainties in the raw SM datasets and fusion methods, these hybrid products create added value over existing SM datasets because of the performance improvement and harmonized spatial, temporal, and vertical coverages, and they provide a new foundation for scientific investigation and resource management.
Using Shapley additive explanations to interpret extreme gradient boosting predictions of grassland degradation in Xilingol, China
Authors:   Batunacun, Wieland Ralf , Lakes Tobia , Nendel Claas
Published: March 2021

Abstract. Machine learning (ML) and data-driven approaches are increasingly used in
many research areas. Extreme gradient boosting (XGBoost) is a tree boosting method that has evolved into
a state-of-the-art approach for many ML challenges. However, it has rarely
been used in simulations of land use change so far. Xilingol, a typical
region for research on serious grassland degradation and its drivers, was
selected as a case study to test whether XGBoost can provide alternative
insights that conventional land-use models are unable to generate. A set of
20 drivers was analysed using XGBoost, involving four alternative
sampling strategies, and SHAP (Shapley additive explanations) to interpret
the results of the purely data-driven approach. The results indicated that,
with three of the sampling strategies (over-balanced, balanced, and
imbalanced), XGBoost achieved similar and robust simulation results. SHAP
values were useful for analysing the complex relationship between the
different drivers of grassland degradation. Four drivers accounted for
99 % of the grassland degradation dynamics in Xilingol. These four drivers
were spatially allocated, and a risk map of further degradation was
produced. The limitations of using XGBoost to predict future land-use change
are discussed.
An update on the 4D-LETKF data assimilation system for the whole
neutral atmosphere
Authors: Koshin Dai , Sato Kaoru , Kohma Masashi , Watanabe Shingo
Published: March 2021

Abstract. The four-dimensional local ensemble transform Kalman filter (4D-LETKF) data assimilation system for the whole neutral atmosphere is updated to better represent disturbances with wave periods shorter than 1 day in the mesosphere and lower thermosphere (MLT) region. First, incremental analysis update (IAU) filtering is introduced to reduce the generation of spurious waves arising from the insertion of the analysis updates. The IAU is better than other filtering methods, and also is commonly used for the middle atmospheric data assimilation. Second, the horizontal diffusion in the forecast model is modified to reproduce the more realistic tidal amplitudes that were observed by satellites. Third, the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) and Special Sensor Microwave Imager/Sounder (SSMIS) observations in the stratosphere and mesosphere also are assimilated. The performance of the resultant analyses is evaluated by comparing them with the mesospheric winds from meteor radars, which are not assimilated. The representation of assimilation products is greatly improved not only for the zonal mean field but also for short-period and/or horizontally small-scale disturbances.

Authors: Rahmah Rona Dwi
Published: March 2021

Abstract. Earthquakes are natural disasters caused by shocks on the earth due to faults and the sudden movement of tectonic rocks that make up the earth's crust. This study of earthquakes will be interesting if explored further from the perspective of the Qur'an because in the Qur'an there are many verses that speak of earthquakes. As explained in the Qur'an Al-Zalzalah verses 1-8. On February 14 2016 to February 23 2016 aftershocks occurred in the Klagon Village Area, Saradan District, Madiun. To analyze when the end of aftershocks ends by using the Least Square Method and the relationship of frequency of aftershocks to times that include the Omori, Omogi 1, Omogi 2 and Utsu methods. The conclusion of this study is the Omogi 2 method which has obtained the correlation coefficient r = 0.195 from the correlation value -1 ≤ r ≤ 1, with the aftershocks ending on day 464 and from the comparison of aftershock frequency corresponding to the graph between the results data calculations with real data (actual data) namely the Omogi 2 method. And basically the term earthquake in the Qur'an can still be said not to make the verses interpreted as a single word containing the meaning of the earthquake as a brief explanation of aftershocks in the perspective of the Qur'an.

The aim of this review is to prove Islamic Fasting during COVID-19 pandemic has negative effect on the spreading of the virus. Basically Water makes up about 60% of one’s body weight. Fasting in Islamic religion is to stop drinking and eating any kinds of food/drinks (Water). even a little amount is forbidden during this month (Ramadan) and the duration is almost 29-30 days. In this review, we have mentioned the impact of fasting in causing Organ/Cellular inflammation, dehydration, dampen cellular/body metabolism which reduces producing enough ATP by mitochondrion through citric acid cycle (CAC) which causes body and organ weakness, dizziness, tiredness and reduction in immune system functioning of the body and increasing the amounts of Reactive Oxygen Species in cells that increasing the possibility of contamination the fasted individual to several important diseases. Infectious diseases including microbial/viral diseases, high abnormal heart rate as a result of falling blood volume which put high pressure on heart and worsen heart disease. The humidity and temperature of the environment in spring time is also help spreading viruses including SARS-CoV-2.

Long Term Follow Up of Bladder Amyloidosis
Authors: Ensley Daniel , Myers David , Kallingal George
Published: March 2021

This is an evaluation of a patient presenting with bladder amyloidosis and a seven year asymptomatic history between gross hematuria episodes. Cystoscopic evaluation showed a diffuse progression of amyloid deposits throughout the bladder. Biopsy confirmed the diagnosis and was negative for malignancy. Further evaluation ruled out systemic disease. To date, he has declined treatment. There is little available literature on long term urologic follow up for these patients. Bladder amyloidosis is rare, but most urologists will encounter it in their clinical practice. There are no agreed upon guidelines or recommendations for long term management of these patients, likely owing to its rarity. This patient had local progression confirmed on biopsy without evidence of malignancy. Evaluation for systemic amyloidosis was also negative. While a single, isolated case, it is unique for the length of follow up, the local progression and lack of symptoms. It is consistent with the low likelihood of systemic progression but does raise the question of how to treat these patients long-term. The authors recommend initial biopsy both to confirm diagnosis and rule out malignancy, evaluation for systemic disease and regular cystoscopic examinations to help direct therapy.

Published: March 2021

A structure due to natural disasters often occurs in Indonesia, and this is caused by the location of Indonesia in the path of earthquakes and volcanoes. Logistics delivery in the form of medicines and food has been hampered, and this is acknowledged by the Indonesian government, which experienced many obstacles when it had to reach an isolated location due to land transportation lines being cut off. So it was designed an Unmanned Aerial Vehicle (UAV) or drone that can deliver survival kits to some places that are isolated due to natural disasters autonomously. Flight orders will be made through the Mission Planner software, which is then sent to the drone using 433 MHz telemetries. Survival kits carried by drones will be dropped using a servo to a predetermined location. The work of Vertical Take-Off Landing (VTOL) for Drop Kits has successfully carried out a mission to deliver survival kits to 4 different locations in one flight. By using the 433 MHz Telemetry, the drone can travel a maximum distance of 120 meters in 5 minutes 10 seconds with a 9 Ah battery capacity.

The agricultural sector is one of the most important economic sectors for Indonesia. However, agriculture itself is accompanied by a number of problems, one of which is pests that attack crops and cause crop failure. The use of robotics in agriculture can now overcome the limited capacity of farmers to monitor large land areas. Using an RC robot that can be controlled automatically via a cell phone monitor screen, human work is greatly facilitated. Artificial intelligence is implanted into a robot to improve the performance of an agricultural robot. This paper discusses designing a pest spraying robot with Neural Network applications for effective and efficient control inputs. The feasibility of the proposed method is proven by simulation conducted in Neuroph Studio and MobotSim. The simulation results show that neural network applications can effectively manage mobile robot movements with an error value of less than 0.1 to avoid the obstacles they encounter to reach the target.

Published: March 2021

Electronic equipment made using old technology or electronic equipment in the entry-level category has not been supported by networking equipment, so for the data communication process, the microcontroller requires interfacing facilities that are in accordance with the electronic equipment used, such as a USB port. With the microcontroller that supports IoT, it allows electronic equipment to communicate over the network. An IoT microcontroller such as the ESP32 is equipped with a WiFi feature but is not equipped with a USB controller feature, while the USB Host max3421e supports the communication process using SPI, so that those two microcontrollers can be used to form an interface using the SPI bus. This interface can be applied to electronic equipment with old technology and entry level electronic equipment for wireless communication. For the needs of making an interface between the ESP32 and max3421e, a software was developed by analyzing the SPI features of the ESP32 and the USB protocol according to the USB device state diagram. The results obtained are the handshake process between systems developed with USB devices in the Low-Speed ​​and Full-Speed ​​categories such as printers, flashdisk, bluetooth mouse and external hard disk, and the device descriptor data of each device tested can be read properly.
Hybrid Feedback Compensation of an External Capacitor-less Low Dropout Voltage Regulator
Authors: Gitzel Daniel , Silva-Martinez Jose , Rivera Rafael
Published: March 2021

Power management has an ever increasing presence in the electronics industry due to the growth of battery powered mobile devices. The low-dropout voltage regulator (LDO) offers improved efficiency over other regulator topologies. However, the architecture suffers from stability issues, which usually necessitates a large off-chip capacitor to ensure the regulator’s performance. This paper presents an alternative topology by removing the bulky external capacitor, thus allowing for greater power system integration. The proposed Current Amplifier Hybrid Compensation (CAHC) scheme implements an active feedback-feedforward compensation system and maintains both a fast transient response and full range alternating current (AC) stability from 0 to 50mA load currents even with a 100pF loading capacitance. The 1.2V External Capacitor-less LDO voltage regulator was designed and simulated in a commercial 0.35um CMOS technology, consuming only 61uA of quiescent current with a dropout voltage of less than 200mV. Simulated results demonstrate that the proposed External Capacitor-less LDO architecture overcomes the typical load transient and AC stability issues encountered in previous architectures. The combined size and component reduction of this architecture presents a more integrable and economic power management system.
Dancing Up the Glass Escalator: Institutional Advantages for Men in Ballet Choreography
Authors: Kelly Colette
Published: March 2021

A dearth of women exists in the upper echelons of ballet choreography. Both academia and the popular press have noted and documented this phenomenon. For instance, in “Breaking the Glass Slipper,” New York Times journalist Michael Cooper recently noted, “When it comes to choreography, at least at most major companies, ballet remains overwhelmingly a man’s world” [1]. Similarly, critic Luke Jennings has noted, “In professional ballet companies, faced with heavier workloads and greater competitive stress than their male colleagues (not to mention the exigencies of pointe work), few women have the time, energy or inclination to consider choreography” [2]. And yet many arguments (such as Jennings’) as to why women do not become choreographers reflect back on women in ballet – claiming a lack of interest, ambition, or even ability – and fail to acknowledge the structural and systemic inequities that promote men in ballet at the expense of their female peers. Even women choreographers themselves tend to claim that women do not become choreographers because of their own choices, constraints, etc., instead of citing systemic structures of unequal opportunity [3]. Failing to acknowledge institutional inequality places the fault of discrimination upon its victims, and ignores the gendered hierarchy within ballet institutions. As an alternative, situating ballet choreography in the context of sociological theory can shed light on how institutions promote token men in ballet to artistic leadership positions, and may help disprove the notion that women do not become choreographers simply because of cultural reasons that relate back to the women themselves.
Title IX: the Female Intercollegiate Athletic Sphere
Authors: Basma Nayla
Published: March 2021

Title IX consists of just thirty-seven words, and it is these words that have transformed the dynamics of the female athletic sphere in the United States. Although the federal law was initially envisioned to assist women in academia, it is currently renowned for its profound impact on American sports [12]. It is an irrefutable fact that Title IX has vastly increased women’s participation in sports, reportedly increasing female participation rates within colleges six-fold from 1972—the year it was passed—to today [3]. Yet, despite the progress made by Title IX, it faces deep challenges in its quest to achieve true equality. Women’s participation rates in sports still lag far behind men, and one cannot ignore this troubling reality that persists in the United States[5]. Thus, the question as to whether or not Title IX has achieved gender equity is highly debatable. This paper intends to illuminate the shortcomings of Title IX’s goal in attaining true equality through analysis of its limitations. Specifically, the essay will first discuss the historical attitudes towards women in sports before Title IX and the structure of the federal law. It will then explore the issues inherent in Title IX, such as the continuation of male preservation, the reduction of men’s sports, and sexual harassment. The scope of this essay will focus mainly on intercollegiate sports.
