Mental health and wellness initiatives supporting United States law enforcement personnel: The current state-of-play
Authors: Drew Jacqueline M. , Martin Sherri
Published: February 2023

The current research provides a national snapshot of availability, access, and perceived effectiveness of wellness services and help-seeking stigma. This study is based on a sample of 3,994 police officers across the United States. The current study found a substantial percentage of officers are accessing wellness services, whether agency-provided, external, or a combination of both. Among officers who were most in need of wellness services, those experiencing some level of psychological distress, over 90% accessed at least one agency-provided or external service. Employee assistance program (EAP) services, formal and informal debriefings with managers and colleagues, chaplaincy services, and peer support were identified as some of the most common types of wellness programs provided by agencies and were also among the most effective wellness services as identified by officers who had accessed them. However, the research did highlight the need to consider gender, years of service, and agency size to provide a more nuanced view of psychological distress,support, and help-seeking stigma. Stigma associated with help-seeking remains a concern that must be addressed in police populations.

Published: February 2023

Public safety personnel (PSP) are at risk of experiencing operational stress injuries (OSIs). The functional impairments caused by OSIs can contribute to challenges with returning to pre-injury operational requirements. A Canadian municipal policing agency developed a peer-led workplace reintegration program (RP) to assist PSP in their workplace reintegration after an illness or injury. Although this RP has been used internationally, there is a paucity of research on this program and its implementation by PSP organizations. The perspectives of key stakeholders are important for capturing the current state of RPs and future directions for the advocacy, implementation, sustainability, and spread of the RP, and to set the stage for future research. The purpose of this study was to explore the experiences and perspectives of key stakeholders engaged in the creation, implementation, facilitation, and execution of RPs in Alberta, Canada. This will help identify strengths, barriers, facilitators, needs, processes, and attitudes associated with the RPs and direction for future research. A qualitative thematic analysis of focus groups (N=8) involving key stakeholders (N=30) from five PSP organizations with RPs was conducted using a community-engaged research approach as part of a larger mixed-methods study. Four key themes emerged from the participants: (1) Integral elements of success, (2) Integral needs, (3) Key areas of growth, and (4) Evolution of the Program. While RPs are highly regarded by the key stakeholders, it is essential that evidence-based research guide the evaluation, modification, implementation, spread, and scale of RPs globally.

Authors: Zulfahmidah  , Safei Imran , Fajriansyah
Published: February 2023

Statin adalah keluarga obat yang digunakan untuk mengobati hiperlipidemia dengan kapasitas yang diakui untuk mencegah kejadian penyakit kardiovaskular. Pemanfaatan statin secara luas dibatasi oleh adanya toksisitas atau intoleransi terkait, yang mempengaruhi tingkat pemantauan obat. Toksisitas atau intoleransi statin bervariasi dari 10-15%. Gejala otot terkait statin adalah toksisitas statin (SAMS) yang paling umum.  Dalam review ini, kami bertujuan untuk melaporkan mekanisme kerja statin yang menyebabkan gejala otot SAMS. Hasil penelitian menunjukkan bahwa statin menyebabkan disfungsi mitokondria akibat adanya stress oksidatif. Mekanisme terjadinya stress oksidatif akibat statin disebabkan karena adanya inhibisi dari protein ubikuinon, aktivasi iNOS, penurunan biogenesis mitokondria, pengurangan fosforilasi oksidatif mitokondria. Secara keseluruhan, data yang dilaporkan dalam tinjauan ini menunjukkan bahwa statin mungkin memiliki efek besar pada fungsi mitokondria terkait stress oksidatif.

Simulation on the effects of the Arduino PID controller parameters using the WOKWI online simulator
Authors: Untoro Suwarno Djoko
Published: February 2023

PID controllers are known in the industrial world as reliable controllers and are studied in universities. The explanation of the ideal PID mathematically often makes it difficult for students to understand the computational process and the implementation that occurs. Often there is difficulty in selecting the correct controller parameters, for example, the Kp, Ki, and Kd parameters. In this study, PID parameters were selected in the form of Kp, Ti, and Td and observed controller output. The Ti parameter as the time integral is easier to understand than the Ki parameter as the gain integral. The Arduino simulator used is wokwi which is an online Arduino simulator. The PID library used is the Arduino Brett Beauregard PID. The results obtained are the effect of changes in the parameters of Kp, Ti, and Td on the controller output. For larger Kp, the controller output is proportional to the amount of input. The larger the Ti, the slower the system output, while the effect of Td is used when the input changes frequently

Authors: Puji Pamungkas Meilinda , Nur Falaq Wendy , Indra Sensuse Dana
Published: February 2023

The Work Unit for Procurement (UKPBJ) of the Indonesian Ministry of Education and Culture has developed a Procurement Information System in Schools (SIPLah) to create effectiveness, efficiency, transparency, and accountability of the procurement ecosystem in education units. 103,619 education units have used SIPLah, this achievement has not met the target of 220,283 schools in 2019 which has increased to 442,960 education units in 2020. The level of user acceptance has a significant influence on achieving the target number of users, but UKPBJ has never conducted research related to this factor. As a result, user acceptance has not become a reference in determining strategies in the socialization and development of SIPLah. This study aims to determine the factors that influence the adoption of SIPLah from the user's perspective in educational units using the Unified Model of E-Government Adoption (UMEGA). In this exploratory research, the perceived risk variable on UMEGA which in the hypothesis has a negative effect, be changed to perceived security so that it has a positive effect and is in line with other hypotheses. There were 150 valid respondents who were analyzed statistically using PLS-SEM with SmartPLS 3.0 software. The results of the study can be concluded that factors of performance expectancy, social influence, facilitating conditions, perceived security, and attitude are factors that must be considered by UKPBJ in determining strategies to socialize and develop SIPLah, because these factors have a significant positive impact on user intentions in education unit to adopt SIPLah.

Authors: Firmansyah Ricki , Utami Ema , Pramono Eko
Published: February 2023

The Internet has given unlimited access to every user through the network used. Vulnerabilities in a network can also be caused by increasing knowledge about hacking and cracking. This is the reason why information and network security are so important. The dataset used in this study uses a dataset from CIC (Canadian Institute Cybersecurity), which covers 7 different attack scenarios, including brute-force, heartbleed, botnet, dos, DDoS, web attacks, and network infiltration from within. The existing attack documents will be extracted. Feature extraction is a process to find the feature values contained in documents for the text mining process. Based on this explanation, this DDoS attack will generate a log where the attack log will be processed and processed into a CSV file for the classification process using Naive Bayes, Random Forest, and Stochastic Gradient Boosting. In this study, researchers used the Naive Bayes, Random Forest, and Stochastic Gradient Boosting algorithms to generate a classification comparison of DDoS attack data so that researchers can find out which algorithm is the best in generating classifications for DDoS attack cases. The results of this study can be concluded that the average accuracy generated by Naive Bayes is 82.45%, the average accuracy generated by the Random Forest algorithm is 99.78%, and the average accuracy generated by the Stochastic Gradient Boosting algorithm is 100%, so that the SGB algorithm is better than Naive Bayes and Random Forest algorithms in classifying DDoS attacks.

Authors: Ariantono Alexander , Untoro Suwarno Djoko
Published: February 2023

The development of technology today has emerged the latest technology in three-dimensional (3D) printer machines. Problems faced by 3D printers include the position of the printer bed that is not horizontal. The position of the printer bed that is not horizontal will cause the 3D print to be skewed. To overcome the problem of tilting the bed of a 3D printer, the auto-level system is needed, which is a system that can correct the position of the base so that it becomes horizontal. In this study, an auto-leveling system was designed and made for four 3D printing base support positions. The drive for the printing press uses a stepper motor with a worm gear transmission. The controller uses an Arduino board and tested various position sensors to determine the slope of the base. The sensor tested is a 3D touch probe sensor. From the test results, the 3D touch probe sensor has a height value difference of not more than 0.05mm from each measurement position. The print base slope reference point is at the center point of the print base. The position of the other corner of the base will be adjusted in height with a stepper motor drive.

Published: February 2023

Artificial intelligence (AI) is one of the remarkable discoveries in the twentieth century. AI is a science related to the creation of machine intelligence capable of performing tasks that previously can only be done by people (Simarmata et al, 2021). It can be said that AI is a breakthrough to create machines that have higher intelligence than machines in general. The current development of AI is aimed at improving learning and problemsolving abilities (Dongre et al, 2020). Accounting is a field that is very suitable for utilizing AI in every part of its information system. AI is expected to be able to help accounting practitioners to improve their performance and develop services they provide. During the development of AI, accounting practices that already adopted AI have resulted in more qualified and diverse outcomes. Various problems that become accounting limitations can be solved with the help of AI, so that the accounting profession can work on a wider area of accounting services, including forensic accounting and financial services and digital investments.
R12 Metamorphosis Theory In Creation Of The Universe With Dyniviti Pradigm And Economic Covid Era
Authors: Aziz R Mochamad
Published: February 2023

The purpose of this study is to analyze the creation of the universe with the Dynic Paradigm according to the R12 Metamorphosis Reproduction (Metamorep) Theory in the 6 stages of the Covid economic era. The theory of R12 metamorphosis is based on the formula R12 and the Metamorphosis pattern. R12 is the Roikhan-12 formula that develops the Initial Edge Concept. The Metamorphosis Pattern is found in the changes in the Butterfly from the beginning. The Dynic Paradigm refers to the content of the scriptures according to truth and facts. This research was conducted in a desk study by collecting sources from scriptures, journals, books, and electronic media. The methodology used is Reflective Qualitative. The method used is metaphor and similarity. The result obtained is the Theory R12 Metamorphosis in the creation of the universe consists of 6 stages. This stage is a combination of the butterfly life cycle plus the creature's breeding cycle. It starts with 1 dot like an egg which contains high-density matter. Then there was a separation which was called the Early Edge Concept. Similar to this concept is the meaning of the Quran Surah Hid 11.114 which is interpreted as a separation from 1 solid dot into 2 parts, namely the edge of the universe's matter has 2 parts, and at the beginning of the universe's matter, there is 1 part in the caterpillar metaphor. Followed by the transformation into a Nebula with smoke covering the galaxy with the metaphor of a cocoon with the reflexivity of the universe praying. The last stage of Metamorphosis is the Butterfly which is represented in the form of the universe starting to develop at the beginning of its perfection. Two additional stages are before the reproductive period with the maturity level of the young universe. The last is the reproduction phase of the universe with a more mature maturity. The Dynic Paradigm is a solution for the development of the theory of the creation of the universe that combines existing theories with the contents of the holy book of the Covid economic era.

On the Possibility of an Event
Authors: Schwartz Daniel
Published: February 2023

This paper introduces a concept of {\it possibility} that may be applied to real-world events that are viewed as having {\it prerequisites} that must be satisfied in order for the event to occur and/or {\it constraints} that may impede or prevent the event's occurrence.  The core idea is to compute the possibility of the event as a function of the probabilities that the prerequisites are satisfied and the constraints are not, and where this function computes possibility values of logical combinations of prerequisites and constraints according to the principles of fuzzy logic.  Thus, this notion of possibility is a hybrid of fuzzy logic and probability theory.  It has the advantage that it provides an objective procedure for determining the possibility of an event insofar as the probabilities of the prerequisites and constraints may be determined by statistical samplings.  This version of possibility would appropriately be applied to problems of planning.  When there are multiple plans available for achieving a goal, this theory can be used to determine which plan is most possible, i.e., easiest or most feasible to complete.  It is speculated that this model of reasoning more correctly captures normal human reasoning about plans.  This may be contrasted with the pure use of probability theory, which can be used to determine which plan is most likely to succeed, but is not typically employed by humans in their everyday decision making.
Deepfake Detection Analyzing Hybrid Dataset Utilizing CNN and SVM
Authors: Dave Rushit , vanamala Mounika
Published: February 2023

Social media is currently being used by many individuals online as a major source of information. However, not all information shared online is true, even photos and videos can be doctored. Deepfakes have recently risen with the rise of technological advancement and have allowed nefarious online users to replace one’s face with a computer-generated face of anyone they would like, including important political and cultural figures. Deepfakes are now a tool to be able to spread mass misinformation. There is now an immense need to  create  models  that  are  able  to  detect  deepfakes  and  keep  them  from  being  spread  as  seemingly  real images  or  videos.  In  this  paper,  we  propose  a  new  deepfake  detection  schema  using two  popular  machine learning algorithms; support vector machine and convolutional neural network, along with a publicly available dataset named the 140k Real and Fake Faces to accurately detect deepfakes in images with accuracy rates reaching as high as 88.33%.

High Performance Wearable Ultrasound as a Human Machine Interface for wrist and hand kinematic tracking
Authors: Grandi Sgambato Bruno , Hasbani Milia , Barsakcioglu Deren Y , Ibáñez Jaime , Jakob Anette , Fournelle Marc , Tang Meng-Xing , Farina Dario
Published: February 2023

Objective: Non-invasive human machine interfaces (HMIs) have high potential in medical, entertainment, and industrial applications. Traditionally, surface electromyography (sEMG) has been used to track muscular activity and infer motor intention. As an alternative HMI approach, ultrasound (US) has been receiving increasing attention as an alternative to EMG. Here, we developed a novel portable US armband system with 24 channels and a multiple receiver approach and compared it with existing sEMG- and US-based HMIs on movement intention decoding. 

Methods: US and motion capture data was recorded while participants performed wrist and hand movements in up to four degrees of freedom (DoFs). A linear regression model was then used to predict the hand kinematics from the US (or sEMG, for comparison) features. The model was also implemented in real-time for a 3-DoF pointer control with minimal training data. 

Results: In offline analysis, the wearable US system achieved an average of 0.94 in the prediction of four DoFs of the wrist and hand. sEMG reached a performance of   = 0.60. 

Conclusion: The newly proposed A-mode US bracelet setup and processing pipeline can regress hand kinematics for up to four DoFs with higher accuracies than other previously published interfaces based on sEMG or US data. The system allowed real-time control with minimal training data 

Significance: Wearable US technology may provide a new generation of HMIs that use muscular deformation to estimate limb movements. The proposed US system here provided robust proportional and simultaneous control over multiple DoFs.

On Secrecy Performance of Mixed THz-FSO Relaying System
Authors: Singh R , Ahmad Ijaz , Huusko Jyrki
Published: February 2023

Terahertz (THz) frequency band and free-space optical (FSO) communication can be proven potential solutions to the spectrum scarcity challenges in the emerging applications in the 6G. In this direction, a mixed THz-FSO relaying system is proposed in this paper. It is assumed that both THz and FSO links encounter fading effects and pointing errors, where the THz link is modeled using α-μ distribution while Málaga (M) distribution is used to characterize the FSO link. Particularly, we conduct the physical layer security (PLS) analysis and derive the secure outage probability into closed-form for two scenarios: 1) THz eavesdropping attack and 2) FSO eavesdropping attack. The effect of THz and FSO links parameters on the secrecy performance are then further investigated in detail. The results show that the security attacks on FSO links are more severe than those on THz links. Interestingly, the improved THz channel conditions adversely affect the security of the proposed mixed THz-FSO system, whereas better FSO channel conditions provide enhanced secrecy.
Machine Learning at the Grid Edge: Data-Driven Impedance Models for Model-Free Inverters
Authors: Li Yufei , Liao Yicheng , Chen Minjie , Wang Xiongfei , Nordström Lars , Mittal Prateek , Poor H. Vincent , Zhao Liang
Published: February 2023

The future electric grid is supported by a vast number of smart inverters interfacing with distributed energy resources at the edge. These inverters’ dynamics are typically characterized as impedances, which are crucial for ensuring grid stability and resiliency. However, the physical implementation of these inverters may change significantly from inverters to inverters and may be kept confidential. Existing analytical impedance models require a complete and precise understanding of system parameters. They can hardly capture the complete electrical behaviors when the inverters are performing complex functions. Online impedance measurements for many inverters across multiple operating points are not scalable. To address these issues, we present InvNet, a machine learning framework to systematically evaluate the effectiveness of data-driven methods for modeling inverter impedance patterns across a wide operation range, even with limited impedance data. Leveraging transfer learning, the InvNet can extrapolate from physics-based models to real-world ones and from one inverter to another with very limited data. This framework demonstrates machine  learning as a powerful tool for modeling and analyzing black-box characteristics of grid-tied inverter systems that cannot be accurately described by traditional analytical methods, such as inverters under model predictive control. Comprehensive evaluations were conducted to verify the effectiveness of the InvNet in various scenarios. All data and models were open-sourced.
Wideband parameter estimation of three-phase untransposed frequency-dependent transmission lines from terminal measurements
Authors: Alqahtani Fahad , Gomez Pablo
Published: February 2023

This paper introduces a wideband parameter estimation approach for untransposed three-phase overhead transmission lines. The proposed method involves an accurate reconstruction of the 2-port nodal model of the line over a wide frequency band from terminal measurements obtained for a set of tests. The minimum norm least-squares method is applied for the solution of the overdetermined mathematical system resulting from these tests. The reconstructed model is further solved for the series impedance and shunt admittance matrices without the need for modal decupling techniques. Terminal voltage and current measurements used as inputs are simulated using software ATP for several tests that consider different tower configurations. The estimated parameters are compared with those computed analytically, with very close results when compared with analytical parameter calculation considering full frequency dependence.
