Published: June 2022

In this work, stochastic analysis of Markov chain model used to examine stock price formation in finite states. The data was subjected to 5-step transition matrix for independent stocks where transition matrix replicated the use of 3-states transition probability matrix. This enables us proffer precise condition of obtaining expected mean rate of return of each stock. Out of the four stocks studied, stock (1), stock (2), stock (3) and stock (4), it was also discovered that stock (1) has the highest mean rate of return:4.0548 and Stock (4) has the best probability of price increasing in the near future:21%. This informs the investor about the behavior of the stocks for the purpose of decision making. From the stochastic analysis, it is revealed that stock price changes are memory-less satisfying the properties of Markov chain. i.e., it converges to a point or becomes stationary at n=5 ie S1:0.1967-0.2354,S2:0.2053-0.1913,S3:0.1972-0.2051 and S4:0.2023-0.1835. Also all states of the transition communicate and are all time dependent.

Ficus glumosa is used extensively in traditional medicine to manage and remedy some health conditions. This study evaluated the impact of F. glumosa leaf extract on selected biochemical indices of testosterone-induced benign prostatic hyperplasia in male Wistar rats. Thirty-six male rats were randomly divided into six groups (n = 6). Rats in the Normal Control (NC) received feed without any special treatment, rats in the Benign Prostatic Hyperplasia Control (BPHC) group were administered 50 mg/Kg body weight testosterone, rats in the Standard Control (STDC) group received 50 mg/Kg body weight testosterone + 5 mg/Kg body weight finasteride, rats in the low dose (LD) group received 50 mg/Kg body weight testosterone + 100 mg/Kg body weight of F. glumosa extract, rats in the medium dose group received 50 mg/Kg body weight testosterone + 200 mg/Kg body weight of F. glumosa extract, rats in the high dose group received 50 mg/Kg body weight testosterone + 400 mg/Kg body weight of F. glumosa extract. The animals received water and feed ad libitum for 28 days. They were anaesthetized (after treatment period) using ketamine hypochlorite. Blood samples were collected, centrifuged and serum harvested for analyses using standard methods and one way ANOVA followed by least square difference (LSD) post-hoc comparison test. Results indicated a significant decrease at p< 0.05 in serum electrolytes (Na and Cl) in the groups treated with F. glumosa extract when compared to the control groups. The serum urea, uric acid and creatinine levels of the groups treated with 200 mg/kg b.w and 400 mg/kg bw of F. glumosa leaf extract decreased significantly when compared to the BPHC standard and normal control groups. Also the serum level of aspartate aminotransferase indicated similar trend. We therefore conclude that F. glumosa leaf extract may attenuate some biochemical indices especially serum electrolytes (Na and Cl), aspartate aminotransferase as well as HDL-c level in testosterone – induced benign prostatic hyperplasia in Wistar rats.

Published: June 2022

Penerimaan negara dari sektor pajak didalam APBN selalu mengalami kenaikan setiap tahunnya. Pajak merupakan tulang punggung penerimaan negara. Sebagai warga negara Indonesia, tentunya kita menyadari betapa esensialnya penerimaan pajak dengan tujuan untuk memenuhi kebutuhan negara. Pentingnya kewajiban seseorang dalam membayar pajak telah digariskan secara konstitusional tepatnya di dalam Pasal 23A UUD 1945. Dengan membayar pajak, warga negara telah berkontribusi dalam hal mewujudkan kesejahteraan umum sebagai cita-cita negara. Namun, dikarenakan banyaknya para wajib pajak yang tidak memiliki itikad baik dan melakukan segala cara agar tidak membayar hutang pajaknya, Maka dari itu diperlukan adanya penerapan gijzeling (penyanderaan) sebagai upaya terakhir dalam rangkaian penagihan pajak. Metode yang digunakan dalam penelitian hukum kali ini adalah pendekatan hukum yuridis normatif, pendekatan ini menekankan kepada ilmu hukum namun juga melihat kenyataan yang berlaku di masyarakat. Berdasarkan hasil penelitian, terdapat beberapa kendala dalam pelaksanaan gijzeling yakni dimulai dari sumber daya manusia yang kurang memadai dimana belum tercukupinya para petugas untuk melakukan penyanderaan (gijzeling). Kedua kurangnya kesadaran dari setiap para penanggung pajak untuk segera melunasi hutang pajaknya, banyak dari para penanggung pajak yang melakukan cara-cara ilegal untuk dapat terbebas dari segala hutang pajak. Dengan demikian untuk dapat mengoptimalisasikan penerapan Gijzeling ini, perlu adanya Penerapan atas prinsip kehati-hatian terhadap para penanggung pajak yang tidak memiliki itikad baik dalam melunasi segala tunggakan pajaknya dan menjadikan Gijzeling sebagai upaya terakhir dalam rangkaian penagihan pajak. Yang kedua, Perlu dilakukan sosialisasi dari lembaga penyanderaan terkait teknis dan manfaat Gijzeling kepada masyarakat.
Quo Vadis Masyarakat Pancasila Pengguna Teknologi?
Authors: Ganda J. Silitonga Samson 
Published: June 2022

Jika Indonesia mengalami 2x pemberontakan Komunis (1948 dan 1965), maka selama 20 tahun pertama negara ini memang mengalami persoalan ideologis yang akut, dan dilanjutkan hingga 1992. Persoalan ideologis juga tak pernah selesai setelah Reformasi 1998, meski dalam spektrum berbeda. Dalam situasi yang berubah, Indonesia mungkin mengalami masalah yang sama. Dan kalau begitu, kondisi apa yang paling mungkin membuat perubahan? Apa dampaknya terhadap penggunaan teknologi? Indonesia telah memiliki ideologi Pancasila yang dirumuskan para pendiri negara. Ideologi berasal dari lapisan-lapisan karakter bangsa, sekaligus juga campuran ideologi-ideologi Internasional. Tetapi, apakah konsekuensinya bagi negara sebesar ini? Dalam pandangan pragmatis, Pancasila adalah sebuah siasat keuntungan sosial maupun ekonomi. Tetapi jika Pancasila tidak menjadi value dan gaya hidup otentik, Pancasila tidak lebih penting dari agama yang dipeluk bangsa Indonesia, pun jika agama dimaksud dapat diinternalisasi secara sosial. Harus ditelusuri berbagai kemungkinan; Pancasila tetap relevan dalam hidup Bangsa Indonesia. Khususnya pada pemanfaatan teknologi yang makin menguat. Belum pernah ada artikel penelitian semacam ini yang menghubungkan ideologi global dengan ideologi nasional, sekaligus sejarah pada tingkat makro sekaligus mikro. Pada tingkat analisis, juga belum pernah ada artikel penelitian yang melihat ihwal perubahan sosial dengan nilai-nilai ideologis yang bersifat empirik. Dengan demikian, kekhususan penelitian ini ialah merangkum berbagai aspek dalam persoalan ideologi, sekaligus tantangannya menghadapi persoalan teknologi.

Aggressive Driving Detection and Alert System Leveraging Current Signal Light Infrastructure
Authors: Li Brian , Li Emma , Li Hui 
Published: June 2022

According to the National Highway Traffic Safety Administration, aggressive driving behaviors are responsible for 54 percent of annual traffic accidents from 2007 to 2019. These accidents cost our society billions of dollars economically. Additionally, hundreds of thousands of innocent lives are taken away and a profound psychological impact is placed on survivors. Existing research on aggressive driving detection mostly relies on devices mounted on vehicles for collecting the data when driving. Such approaches, however, will be hard to enforce in real life because of consumer privacy concerns. Also, not all existing vehicles can have the monitoring system, thus the overall effectiveness is limited. The approach that we propose here is to leverage the existing infrastructure of traffic lights to enforce the detection of aggressive driving behaviors for all vehicles at all times. The undertaken approach introduces centralized detection and alert systems that can work with an existing traffic light control system and a real digital map system as a real-world application. The detection system utilizes both traffic lights and speed sensors mounted alongside to detect aggressive driving behaviors at intersections. The alert system adopts an efficient specialized graph traversal algorithm to pinpoint impacted traffic lights and alert only the drivers nearby those lights. To demonstrate the approach, we prototyped both a detection system and an alert system running on an Arduino board. We verified their consistent high accuracy and real-time response by applying them to an experimental setup that consists of streets and intersections with traffic lights and infrared sensors.

Contrasting responses of phytoplankton productivity between coastal and offshore surface waters in the Taiwan Strait and the South China Sea to short-term seawater acidification

Published: June 2022

Abstract. Seawater acidification (SA) has been documented to either inhibit, enhance, or result in no effect on marine primary productivity (PP). In order to examine the effects of SA in changing environments, we investigated the influences of SA (a decrease of 0.4 pHtotal units with corresponding CO2 concentrations in the range of 22.0–39.7 µM) on PP through deck-incubation experiments at 101 stations in the Taiwan Strait and the South China Sea, including the continental shelf and slope, as well as the deep-water basin. The daily primary productivities in surface seawater under incident solar radiation ranged from 17–306 µg C (µg Chl a)−1 d−1, with the responses of PP to SA being region-dependent and the SA-induced changes varying from −88 % (inhibition) to 57 % (enhancement). The SA treatment stimulated PP in surface waters of coastal, estuarine, and shelf waters but suppressed it in the South China Sea basin. Such SA-induced changes in PP were significantly related to in situ pH and solar radiation in surface seawater but negatively related to salinity changes. Our results indicate that phytoplankton cells are more vulnerable to a pH drop in oligotrophic waters. Contrasting responses of phytoplankton productivity in different areas suggest that SA impacts on marine primary
productivity are region-dependent and regulated by local environments.
Implementation and evaluation of the unified stomatal optimization approach in the Functionally Assembled Terrestrial Ecosystem Simulator (FATES)

Published: June 2022

Abstract. Stomata play a central role in regulating the exchange of carbon
dioxide and water vapor between ecosystems and the atmosphere. Their
function is represented in land surface models (LSMs) by conductance models.
The Functionally Assembled Terrestrial Ecosystem Simulator (FATES) is a
dynamic vegetation demography model that can simulate both detailed plant
demographic and physiological dynamics. To evaluate the effect of stomatal
conductance model formulation on forest water and carbon fluxes in FATES, we
implemented an optimality-based stomatal conductance model – the Medlyn
(MED) model – that simulates the relationship between photosynthesis (A) and
stomatal conductance to water vapor (gsw) as an alternative to the FATES
default Ball–Woodrow–Berry (BWB) model. To evaluate how the behavior of
FATES is affected by stomatal model choice, we conducted a model sensitivity
analysis to explore the response of gsw to climate forcing, including
atmospheric CO2 concentration, air temperature, radiation, and vapor
pressure deficit in the air (VPDa). We found that modeled gsw values
varied greatly between the BWB and MED formulations due to the different
default stomatal slope parameters (g1). After harmonizing g1 and
holding the stomatal intercept parameter (g0) constant for both model
formulations, we found that the divergence in modeled gsw was limited to
conditions when the VPDa exceeded 1.5 kPa. We then evaluated model
simulation results against measurements from a wet evergreen forest in
Panama. Results showed that both the MED and BWB model formulations were
able to capture the magnitude and diurnal changes of measured gsw and A but underestimated both by about 30 % when the soil was
predicted to be very dry. Comparison of modeled soil water content from
FATES to a reanalysis product showed that FATES captured soil drying well,
but translation of drying soil to modeled physiology reduced the models'
ability to match observations. Our study suggests that the parameterization
of stomatal conductance models and current model response to drought are the
critical areas for improving model simulation of CO2 and water fluxes
in tropical forests.
