Coupled Dynamic Modeling and Control of Aerial Continuum Manipulation Systems
Authors: Samadikhoshkho Zahra , Ghorbani Shahab , Janabi-Sharifi Farrokh
Published: August 2023

Aerial continuum manipulation systems (ACMSs) were newly introduced by integrating a continuum robot (CR) into an aerial vehicle to address a few issues of conventional aerial manipulation systems such as safety, dexterity, flexibility and compatibility with objects. Despite the earlier work on decoupled dynamic modeling of ACMSs, their coupled dynamic modeling still remains intact. Nonlinearity and complexity of CR modeling make it difficult to design a coupled ACMS model suitable for practical applications. This paper presents a coupled dynamic modeling for ACMSs based on the Euler–Lagrange formulation to deal with CR and the aerial vehicle as a unified system. For this purpose, a general vertical take-off and landing vehicle equipped with a tendon-driven continuum arm is considered to increase the dexterity and compliance of interactions with the environment. The presented model is independent of the motor’s configuration and tilt angles and can be applied to model any under/fully actuated ACMS. The modeling approach is complemented with a Lyapunov-wise stable adaptive sliding mode control technique to demonstrate the validity of the proposed method for such a complex system. Simulation results in free flight motion scenarios are reported to verify the effectiveness of the proposed modeling and control techniques.
Chrystia Freeland will have to navigate misogyny in her new roles
Authors: Raney Tracey , Berdahl Loleen
Published: August 2023

Chrystia Freeland’s influence in the new Liberal minority government has been upgraded significantly with Justin Trudeau’s recent cabinet announcements.

She now serves in dual roles as deputy prime minister and minister of intergovernmental affairs. Freeland will also play key leadership roles on the “agenda, results and communications” and the “economy and the environment” cabinet committees.

In addition to her new formal mandates, however, Freeland will likely have to face another ongoing problem in Canadian politics: growing resentment and anger directed at women politicians.
#MeToo turns 5: Taking stock of gender-based violence in Canadian politics
Authors: Raney Tracey
Published: August 2023

Five years ago, women around the world began publicly disclosing their experiences of sexual assault and harassment on social media using the hashtag #MeToo.

This milestone provides us with an opportunity to reflect on how Canada has dealt with its own supposed #MeToo reckoning and misogyny in Canadian politics more specifically.

The events of 2017 came 11 years after Tarana Burke founded the #MeToo movement to raise awareness about the violence Black women and girls experience in the United States. The #MeToo hashtag went viral in October 2017 after sexual misconduct allegations against Hollywood mogul Harvey Weinstein became public.

Five years later, what lessons have we learned about gender-based violence in Canadian politics?

This study aims to determine the contribution of science, such as education and law, in overcoming immoral behavior in the educational world. This study uses qualitative research methods with literature reviews. The results of this research indicate that immoral behavior in education occurs as a result of weak supervision, irresponsibility between different parties in the educational world and religious teaching in learning as a form of overcoming. In fact, the violence in schools is a national problem that must be stopped as it is an attempt to uphold the rights of children as stated in the Child Protection Act. On the other hand, when dealing with immoral behavior that occurs in students, the teacher has the freedom and authority to punish educational behavior. Sanctions can consist of reprimands and/or warnings, both verbally and in writing, but also pedagogical punishments in accordance with the education rules, the teacher's code of ethics and laws and regulations.

Published: August 2023

Indonesia is a country with the largest number of active volcanoes in the world and has the potential to erupt. This causes primary and secondary disasters, one of which is secondary disasters caused by lava floods during heavy rains. So disaster mitigation is needed by simulating lava floods to find out the predictions of speed, volume, height and area affected by lava floods. The simulation was carried out using SIMLAR software, carried out on Gendol River which is one of the watersheds that has the threat of lahar flooding. The test was carried out with 3 hyetograph patterns and for each pattern there were 3 simulations with different rainfall intensities, namely 162 mm, 243 mm and 324 mm. From these tests, the speed values ​​in patterns 1, 2 and 3 increased each simulation to the existing simulation. The speed value obtained by pattern 1 at 162 mm rain intensity is 2.35 m/s, at 243 mm rain intensity is 2.48 m/s, and at 324 mm rain intensity is 2.58 m/s. In addition, at high yields, volume and area also increase in each simulation due to the higher rainfall intensity. This proves that the intensity of rain is directly proportional to speed, volume, area and height. In addition, the hyetograph pattern also affects the peak hours when the maximum volume, maximum height and maximum speed are reached.

Rainfall is an indispensable component of hydrological analysis. However, the observational rainfall data has problems such as incomplete and shorter data. Rainfall measurements using high resolution and wide area coverage satellites provide a potential alternative for various hydrological analyses. But the measurement of rainfall using satellites is not necessarily accurate due to the difference in resolution of the observational rainfall data, especially in Central Kalimantan Province. This study aims to determine the accuracy of satellite rainfall data based on observational rain data and evaluate it. Evaluation is done by looking for the relationship between the two-rainfall data using a regression model. The results showed that the TRMM total grid rainfall data (R2 = 0.5233) had a higher correlation to the observational rainfall data compared to the GPM rainfall data (R2 = 0.3909). Furthermore, a discharge analysis was carried out in one of the watersheds in Central Kalimantan, namely the Kahayan watershed using the Nakayasu Hydrograph Synthesis Unit method with a certain return period with satellite rainfall data input which has a fairly good accuracy based on the results of the analysis. The estimated discharge with return periods of 2, 5, 10, 25, and 50 years for TRMM rainfall data before correction are 1976.74m3/s, 2165.66 m3/s, 2239.19 m3/s, 2313.63 m3/s, 2375.69 m3/s respectively, and for the estimated discharge after correction are 2549.35 m3/s, 2670.59 m3/s, 2736.42 m3/s, 2801.37 m3/s, 2854.82 m3/s.

Authors: Karimah Rofikatul , Abadi Khairul , Ridwan Mochammad , Kamila Iklil Lutfiyah
Published: August 2023

Mortar is a building material that serves to glue bricks, bricks, plaster, and so on. As an adhesive, mortar has a viscosity that is useful in determining compressive strength. In the manufacture of mortar, SNI 03-6882-2002 requires the use of clean fresh water, but in reality, as an archipelagic country, some of the islands in Indonesia are isolated from fresh water. As a result, freshwater becomes an expensive item, because it is imported from other areas, so it requires transportation costs. If the mortar is required to use water according to SNI standards, the project implementation costs will be expensive. In areas that do not have adequate fresh water, mortar is made using water obtained on-site, including brackish, salt, and sea water. Seawater contains elements of NaCl salts which can bind Calcium Hydroxide (CaOH) compounds, reducing the CaOH compounds in the mortar will increase the compressive strength of the mortar. In this study, a review of brine as a mixture of mortar materials was carried out with the aim of knowing the performance of mortar containing salt water by compressive strength test and Absorption test. The amount of salt water added to the mortar mixture is 0%; 0.5%; 1%; 1.5%; 2%; 2.5% ; 3%; 3.5% of the volume of water used as a mortar mix. Cube test object measuring 50x50x50 mm3 in the amount of 5 in each treatment, made from a mixture of 1PC: 2.75 Sand (based on weight ratio), with a water-cement factor (FAS) of 0.45. The test results obtained the compressive strength value of the mortar with the addition of salt water can reduce the compressive strength value but the use of brine with a content of 3.5% is still in the category of minimum permissible pressure according to SNI03-6882-2002. While the absorption value of the mortar can increase fiber strength with increasing addition of 3.0% brine.

Avalanche often happened during a small crack on the slope. The increasing of crack’s propagation impact the cohesion and internal friction angle which causing the soil on the slope shrinkage on its strength to shift and this could cause the avalanche on the slope. There are several inquiries had been conducted in the laboratory to further study the effect of the crack’s propagation towards cohesion and internal friction angle. The inquiry in the laboratory conducted using fricative test equipment with variation of crack’s propagation. The soil sample that were tested was from Lok Buntar village, Banjar district, South Kalimantan within the varied crack’s propagation. The cohesion value and internal friction angle from the inquiry were analyzed using Fellinius method using slope model from avalanche restoration project at Muara Teweh - Benangin road border, East Kalimantan. The result of the inquiry from the laboratory showed that the increasing of the crack’s propagation decreased the cohesion and internal friction angle, this put the safety factor of the slope in a critical condition with crack at 60%. This research is expected to be able to contribute on the prevention of the upcoming avalanche on a similar soil type and model
Impact of Traffic Sign Diversity on Autonomous Vehicles
Authors: Aldoski Ziyad N. , Koren Csaba
Published: August 2023

Traffic sign classification is indispensable for road traffic systems, including automated ones. There is a fundamental difference in the visual appearance of traffic signs from one country to another. Each dataset has its design standards and regulations based on shape, color, and information content, making implementing classification and recognition techniques more difficult. This paper aims to assess the influence of traffic sign diversity on autonomous vehicles (AVs) by reviewing several previous studies, comparing, summarizing their results, and focusing on classifying and detecting traffic sign datasets based on color, shape, and deep learning spaces using various methods and applications. Furthermore, it covers the main challenges facing road designers and planners considering changes to road safety infrastructure. It will be argued that compiling and standardizing a comprehensive global database of traffic signs is very difficult because it is costly and complex in application. However, it is still one of the possible solutions for the coming decades. Recommendations for future developments are also presented in this study.

We study the semi-linear Beltrami equation $\omega_{\bar{z}}-\mu(z) \omega_z=\sigma(z)q(\omega(z))$ and show that it is closely related to the corresponding semi-linear equation of the form ${\rm div} A(z)\nabla\,U(z)=G(z) Q(U(z)).$ Applying the theory of completely continuous operators by Ahlfors-Bers and Leray-Schauder, we prove existence of regular solutions both to the semi-linear Beltrami equation and to the given above semi-linear equation in the divergent form, see Theorems 1.1 and 5.2. We also derive their representation through solutions of the semi-linear Vekua type equations and generalized analytic functions with sources. Finally, we apply Theorem 5.2 for several model equations describing physical phenomena in anisotropic and inhomogeneous media.

Authors: McAllister LT , Van Leeuwen TE , Conway C , Wälle M , Abrahams M
Published: August 2023

Wild fish have been shown to associate with sea cage aquaculture and consume waste feed; however, little is known about the effects of waste feed consumption on wild fish. We used Atlantic cod Gadus morhua collected in the direct vicinity of sea cages and reference Northwest Atlantic Fisheries Organization divisions, either outside the direct vicinity (‘local division’) or completely removed from aquaculture (‘outside divisions’), to compare length, weight, and condition for cod ages 2 to 4. Concentrations of vegetable oil-based fatty acids (linoleic acid and α-linolenic acid) were then used as biomarkers for waste feed consumption to determine their role in explaining differences in length, weight, and Fulton’s condition index among cage-associated cod. Age 2 cage-associated cod were in lower condition than age 2 cod from the local division and lighter than age 2 cod from all outside divisions. Age 3 cage-associated cod were comparable to age 3 cod from the local division but in lower condition than age 3 cod from all outside divisions. However, age 4 cage-associated cod were longer and heavier than age 4 cod from the local division, but in lower condition than age 4 cod from 2 of 3 outside divisions. Additionally, there were positive relationships between fatty acid concentrations and length and weight for age 2 cage-associated cod, but no significant relationships for age 3 or 4 cage-associated cod. Results suggest the effects of waste feed consumption are contradictory but not consistent enough to disrupt established growth and condition patterns among divisions.
PREDICTING INDIVIDUAL INVESTOR’S INTENTION TO INVEST: A COMPARISON BETWEEN ACTUAL AND PERCEIVED FINANCIAL KNOWLEDGE
Authors: Dalina Amonhaemanon  , Pornpen Vora-sittha
Published: August 2023

This paper aimed to empirically check and evaluate statistically significant differences in structural relationships of actual and perceived financial knowledge, risk tolerance, and risky investment intention, via in total of 995 questionnaires sent to a sample group of the informal laborers in southern Thailand. Partial least squares structural equation modelling was used to analyze the results. It is worth noting that even though both actual and perceived financial knowledge affected each individual’s risk tolerance, still perceived knowledge affected more the individual’s risk tolerance. The actual and perceived financial knowledge that the individuals possess would enable them to make sound investments. Our study added the multi-group analyses in order to investigate if gender affected each individual’s decision-making on investment. The results revealed that in the case of men, both actual and perceived financial knowledge positively correlated with risky investment intention, whereas in the case of women only actual financial knowledge did. The key point from our study indicated that confidence or self-perceived knowledge was a significant factor affecting individual decision-making on investments. Hence, the educators and policymakers should provide effective lessons on financial knowledge by creating actual knowledge in order to help avoid overconfidence.

Published: August 2023

This study was conducted to assess the vulnerability of Islamic banking credit portfolios under macroeconomic shocks and their impact on NPFs, using the linear regression analysis. From the three proposed models, namely OLS, ARIMAX and Error Correction Model (ECM), the ECM model was selected as the best. By using the Montecarlo simulation, an estimate was made of the possible future value of the NPF in Islamic banking. The study established that exchange rates, economic disparities, inflation, economic growth and interest rates showed positive and significant effects on bank credit risk whereas inflation produced negative effects. The non-performing finance (NPF) was also estimated using the Montecarlo simulation using one million trials. The results were subsequently used to conduct a stress test for the projected NPF. With 99% confidence, the maximum potential value of bad credit was 21%. The maximum NPF bad credit was attained under confidence level of 95%.
THE DETERMINANT OF CONSIGNMENT GOODS IN CROSS-BORDER E-COMMERCE
Authors: Masruri Muchtar  , Vahri Firmansyah
Published: August 2023

E-commerce has started to dominate imported goods. This situation makes it problematic for domestic industries to compete with foreign products. The Ministry of Finance of the Republic of Indonesia adjusted the de minimis threshold to USD3 from USD75 to anticipate it. The policy is expected to limit imported products and support the sustainability of small and medium enterprises (SMEs). Research related to imports through e-commerce in Indonesia still needs to be completed. This study aims to analyse several variables predicted to affect cross-border e-commerce. This research employs the ordinary least square (OLS) and error correction model (ECM) approach to examine the effect of exchange rates, inflation, income, and discounts on imports from e-commerce. A one-way ANOVA test was used to find the difference in the average imports of the three de minimis groups (USD100, USD75, and USD3). It utilized transaction data obtained from the Lazada e-commerce platform. Lazada was chosen because it is one of the biggest marketplaces in Indonesia. The test result found that discounts significantly affect the short and long-term import value. In addition, lowering de minimis tends to decrease the average import of consignment goods. The result implies that the government should improve regulations to support SMEs as one of the keys to the success of the National Economic Recovery (PEN) from the COVID-19 pandemic.

Infrastructure is one of the determinants of destination competitiveness. There are two kinds of infrastructure namely hard infrastructure and soft infrastructure. The current study investigated the impact of hard infrastructure (transportation, telecommunication, accommodation) and soft infrastructure (government tourism policy, health services, and safety and security) on perceived destination competitiveness from tourists’ points of view. The study was conducted based on quantitative research. A PLS-SEM analysis was performed by using WarpPLS. The result indicated that transportation, accommodation, and health services have a significant relationship with perceived destination competitiveness. This study is expected to benefit policymakers and industry players in terms of decision-making. Besides, this study will equip more literature and evidence for scholars to perform further studies in the field.
Critical Dystopia: Local Narrative in the Threshold in Ahmed
Khaled Towfik’s Utopia
Authors: Resheq Reem
Published: August 2023

This study is an exploration of critical dystopia within a postmodern context. Literary and historical viewpoints associate dystopia with the failed utopia of twentieth-century totalitarianism manifested in regimes of extreme coercion, inequality, and slavery. Raffaella Baccolini and Tom Moylan, of whose perspective this study makes use, theorize that critical dystopia provides a potential for change through rejecting the traditional dystopian ending marked by the subjugation of the individual. Problematizing critical dystopia further, the study proposes that the critical orientation of this sub-genre originates mainly from the “local narrative” of a subject whose agency generates from his position in the “threshold” between those in and under control, combined with the “counter-conducts” he uses to acquire knowledge, memory, and awakened consciousness. As a full agent, the subject resists the “utopian” “metanarrative” of an oppressive system/structure and offers possibilities of meaning in a process of “différance” which entails a potential for change. This proposition is clarified through the close reading of Ahmed Khaled Towfik’s Utopia (2011; first published in Arabic in 2008). The novel is discussed as a critical dystopian text in which Gaber, the subject in the “threshold,” opposes the totalitarian regime of Utopia in his “local narrative.”.
N-Word Licensing

The paper, conducted within the framework of the Minimalist Program
(Chomsky 1995), considers aspects of the licensing relation which obtains between
Negation (Neg) and N-words in Amazigh. By N-words, I mean elements like ‘ħtta+NP’
(no-one), which are licensed by Neg. The paper shows that the Neg-N-word relation in
this language is one of feature checking, with Neg-features present on the N-word
requiring to be paired with corresponding features on the functional head Neg prior to
Spell-Out in the position they occupy, i.e. base generated in the c-command domain of
Neg. It provides further evidence for the analysis of N-words from Moroccan Arabic, one
which argues for a different view of feature checking/licensing from that proposed in
Chomsky 1995..

Major histocompatibility complex Class I (MHC-I) molecules bind to peptides derived from intracellular antigens and present them on the surface of cells, allowing the immune system (T cells) to detect them. Elucidating the process of this presentation is essential for regulation and potential manipulation of the cellular immune system. Predicting whether a given peptide binds to an MHC molecule is an important step in the above process and has motivated the introduction of many computational approaches to address this problem. NetMHCPan, a pan-specific model for predicting binding of peptides to any MHC molecule, is one of the most widely used methods which focuses on solving this binary classification problem using shallow neural networks. The recent successful results of Deep Learning (DL) methods, especially Natural Language Processing (NLP-based) pretrained models in various applications, including protein structure determination, motivated us to explore their use in this problem. Specifically, we consider the application of deep learning models pretrained on large datasets of protein sequences to predict MHC Class I-peptide binding. Using the standard performance metrics in this area, and the same training and test sets, we show that our models outperform NetMHCpan4.1, currently considered as the-state-of-the-art.

Genes involved in mycoremediation were identified by comparative genomics analysis in 10 armillarioid species and selected groups of white-rot Basidiomycota (14) and soft-rot Ascomycota (12) species to confine the distinctive bioremediation capabilities of the armillarioids. The genomes were explored using phylogenetic principal component analysis (pPCA), searching for genes already documented in a biocatalysis/biodegradation database. The results underlined a distinct, increased potential of aromatics-degrading genes/enzymes in armillarioids, with particular emphasis on a high copy number and diverse spectrum of benzoate 4-monooxygenase [EC:1.14.14.92] homologs. In addition, other enzymes involved in the degradation of various monocyclic aromatics were more abundant in the armillarioids than in the other white-rot basidiomycetes, and enzymes involved in the degradation of polycyclic aromatic hydrocarbons (PAHs) were more prevailing in armillarioids and other white-rot species than in soft-rot Ascomycetes. Transcriptome profiling of A. ostoyae and A. borealis isolates confirmed that several genes involved in the degradation of benzoates and other monocyclic aromatics were distinctively expressed in the wood-invading fungal mycelia. Data were consistent with armillarioid species offering a more powerful potential in degrading aromatics. Our results provide a reliable, practical solution for screening the likely fungal candidates for their full biodegradation potential, applicability, and possible specialization based on their genomics data.

Environmental pollution with potentially toxic elements (PTEs) has become one of the critical and pressing issues worldwide. Although these pollutants occur naturally in the environment, their concentrations are continuously increasing, probably as a consequence of anthropic activities. They are very toxic even at very low concentrations and hence cause undesirable ecological impacts. Thus, the cleanup of polluted soils and water has become an obligation to ensure the safe handling of the available natural resources. Several remediation technologies can be followed to attain successful remediation, i.e., chemical, physical, and biological procedures; yet many of these techniques are expensive and/or may have negative impacts on the surroundings. Recycling agricultural wastes still represents the most promising economical, safe, and successful approach to achieving a healthy and sustainable environment. Briefly, biochar acts as an efficient biosorbent for many PTEs in soils and waters. Furthermore, biochar can considerably reduce concentrations of herbicides in solutions. This review article explains the main reasons for the increasing levels of potentially toxic elements in the environment and their negative impacts on the ecosystem. Moreover, it briefly describes the advantages and disadvantages of using conventional methods for soil and water remediation then clarifies the reasons for using biochar in the clean-up practice of polluted soils and waters, either solely or in combination with other methods such as phytoremediation and soil washing technologies to attain more efficient remediation protocols for the removal of some PTEs, e.g., Cr and As from soils and water.
Pyroptosis and gasdermins—Emerging insights and therapeutic opportunities in metabolic dysfunction-associated steatohepatitis

Published: August 2023

In recent years, there has been a rapid expansion in our understanding of regulated cell death, leading to the discovery of novel mechanisms that govern diverse cell death pathways. One recently discovered type of cell death is pyroptosis, initially identified in the 1990s as a caspase-1-dependent lytic cell death. However, further investigations have redefined pyroptosis as a regulated cell death that relies on the activation of pore-forming proteins, particularly the gasdermin family. Among the key regulators of pyroptosis is the inflammasome sensor NOD-like receptor 3 (NLRP3), a critical innate immune sensor responsible for regulating the activation of caspase-1 and gasdermin D. A deeper understanding of pyroptosis and its interplay with other forms of regulated cell death is emerging, shedding light on a complex regulatory network controlling pore-forming proteins and cell fate. Cell death processes play a central role in diseases such as metabolic dysfunction-associated steatotic liver disease, metabolic dysfunction-associated steatohepatitis, autoinflammatory disorders, and cancer. Cell death often acts as a starting point in these diseases, making it an appealing target for drug development. Yet, the complete molecular mechanisms are not fully understood, and new discoveries reveal promising novel avenues for therapeutic interventions. In this review, we summarize recent evidence on pathways and proteins controlling pyroptosis and gasdermins. Furthermore, we will address the role of pyroptosis and the gasdermin family in metabolic dysfunction-associated steatotic liver disease and steatohepatitis. Additionally, we highlight new potential therapeutic targets for treating metabolic dysfunction-associated steatohepatitis and other inflammatory-associated diseases.

Objective

The present study aims to investigate the effect of Helicobacter pylori (Hp) infection on gastric mucosal microbiota in patients with chronic gastritis.

Methods

Here recruited a population of 193 patients with both chronic gastritis and positive rapid urease, including 124 patients with chronic atrophic gastritis (CAG) and 69 patients with chronic non-atrophic gastritis (nCAG). Immunoblotting was used to detect four serum Hp antibodies (UreA, UreB, VacA and CagA) to determine the types of virulent Hp-I and avirulent Hp-II infections. Gastric microbiota was profiled by 16S rRNA gene V3-V4 region, and R software was used to present the relationship between the microbial characteristics and the type of Hp infection.

Results

In the stomach of patients with Hp-positive gastritis, the dominant gastric bacterial genera included Ralstonia (23.94%), Helicobacter (20.28%), Pseudonocardia (9.99%), Mesorhizobium (9.21%), Bradyrhizobium (5.05%), and Labrys (4.75%). The proportion of Hp-I infection was significantly higher in CAG patients (91.1%) than in nCAG patients (71.0%) (P < 0.001). The gastric microbiota richness index (observed OTUs, Chao) was significantly lower in CAG patients than in nCAG patients (P <0.05). Compared with avirulent Hp-II infection, virulent Hp-I infection significantly decreased the Shannon index in CAG patients (P <0.05). In nCAG patients, Hp-I infected patients had lower abundances of several dominant gastric bacteria (Aliidiomarina, Reyranella, Halomonas, Pseudomonas, Acidovorax) than Hp-II infected patients. Meanwhile, in CAG patients, Hp-I infected patients occupied lower abundances of several dominant oral bacteria (Neisseria, Staphylococcus and Haemophilus) than Hp-II infected patients. In addition, bile reflux significantly promoted the colonization of dominant oral microbiota (Veillonella, Prevotella 7 and Rothia) in the stomach of CAG patients. There was no significant symbiotic relationship between Helicobacter bacteria and non-Helicobacter bacteria in the stomach of nCAG patients, while Helicobacter bacteria distinctly linked with the non-Helicobacter bacteria (Pseudolabrys, Ralstonia, Bradyrhizobium, Mesorhizobium and Variovorax) in CAG patients.

Conclusions

Virulent Hp infection alters the gastric microbiota, reduces microbial diversity, and enhances the symbiotic relationship between the Helicobacter bacteria and non-Helicobacter bacteria in patients with chronic gastritis. The data provides new evidence for treating Hp infection by improving the gastric microbiota.
