2,6-Dichlorobenzamide (BAM), 2-(trifluoromethyl)benzamide (TBAM), 2-(trifluoromethyl)benzoic acid (TBA), and 3-chloro-5-(trifluoromethyl)pyridine-2-carboxylic acid (PCA) are degradation by-products of fluopicolide and fluopyram fungicides. In this work, a detailed theoretical study of their different molecular, spectroscopic and thermochemical properties was carried out with different formulations of the density functional theory and high-level model chemistries. The mean values of −146.0 ± 6.3, −763.2 ± 6.3, −949.0 ± 6.3, and −919.4 ± 6.3 kJ mol−1 for the standard enthalpies of formation of BAM, TBAM, TBA and PCA, respectively, were derived for the first time at the G3MP2//DFT and G4MP2//DFT levels of theory (DFT = B3LYP, BMK, and B98). Additionally, a good agreement between formation enthalpies derived from isodesmic reaction approach and from Benson’s group additivity method was obtained.

Published: September 2023

Nowadays, the use of carbon-neutral materials is an urgent need because of energy consumption and CO2-emissions concerns. Thus, the use of ladle furnace steel slags (LFSs) is becoming common in asphalt pavement fields. One of the limitations on using LFSs is linked to swelling potential because of the changes in chemical structure due to the hydration of their components. In this study, two different asphalt binders, neat and 3.5 % styrene-butadiene-styrene modified, were mixed with limestone coarse aggregates and two fillers (limestone and LFSs) to analyze the swelling potential and the performance levels of hot mix asphalts containing not-hydrated LFSs as filler. The analysis was conducted performing the SuperPave indirect tensile test protocol at 10°C and by using a 3D-digital image correlation metadata model (3D-DICM) capable of computing the volumetric expansion of materials after four different periods of conditioning in water (24, 48, 168, and 336 h). The results showed no significant differences among the analyzed materials, highlighting that the volumetric expansion is mainly linked to the aggregates’ water absorption. On the other hand, conditioning time seems to affect the deformability of the mixtures, influencing performance level.
A bifunctional kinase–phosphatase module balances mitotic checkpoint strength and kinetochore–microtubule attachment stability

Published: September 2023

Two major mechanisms safeguard genome stability during mitosis: the mitotic checkpoint delays mitosis until all chromosomes have attached to microtubules, and the kinetochore–microtubule error‐correction pathway keeps this attachment process free from errors. We demonstrate here that the optimal strength and dynamics of these processes are set by a kinase–phosphatase pair (PLK1‐PP2A) that engage in negative feedback from adjacent phospho‐binding motifs on the BUB complex. Uncoupling this feedback to skew the balance towards PLK1 produces a strong checkpoint, hypostable microtubule attachments and mitotic delays. Conversely, skewing the balance towards PP2A causes a weak checkpoint, hyperstable microtubule attachments and chromosome segregation errors. These phenotypes are associated with altered BUB complex recruitment to KNL1‐MELT motifs, implicating PLK1‐PP2A in controlling auto‐amplification of MELT phosphorylation. In support, KNL1‐BUB disassembly becomes contingent on PLK1 inhibition when KNL1 is engineered to contain excess MELT motifs. This elevates BUB‐PLK1/PP2A complex levels on metaphase kinetochores, stabilises kinetochore–microtubule attachments, induces chromosome segregation defects and prevents KNL1‐BUB disassembly at anaphase. Together, these data demonstrate how a bifunctional PLK1/PP2A module has evolved together with the MELT motifs to optimise BUB complex dynamics and ensure accurate chromosome segregation.
CryoET shows cofilactin filaments inside the microtubule lumen
Authors: Ventura Santos Camilla , Rogers Stephen L , Carter Andrew P
Published: September 2023

Cytoplasmic microtubules are tubular polymers that can harbor small proteins or filaments inside their lumen. The identities of these objects and mechanisms for their accumulation have not been conclusively established. Here, we used cryogenic electron tomography of Drosophila S2 cell protrusions and found filaments inside the microtubule lumen, which resemble those reported recently in human HAP1 cells. The frequency of these filaments increased upon inhibition of the sarco/endoplasmic reticulum Ca2+ ATPase with the small molecule drug thapsigargin. Subtomogram averaging showed that the luminal filaments adopt a helical structure reminiscent of cofilin‐bound actin (cofilactin). Consistent with this, we observed cofilin dephosphorylation, an activating modification, in cells under the same conditions that increased luminal filament occurrence. Furthermore, RNA interference knock‐down of cofilin reduced the frequency of luminal filaments with cofilactin morphology. These results suggest that cofilin activation stimulates its accumulation on actin filaments inside the microtubule lumen.

Published: September 2023

Snyder–Robinson syndrome (SRS) results from mutations in spermine synthase (SMS), which converts the polyamine spermidine into spermine. Affecting primarily males, common manifestations of SRS include intellectual disability, osteoporosis, hypotonia, and seizures. Symptom management is the only treatment. Reduced SMS activity causes spermidine accumulation while spermine levels are reduced. The resulting exaggerated spermidine:spermine ratio is a biochemical hallmark of SRS that tends to correlate with symptom severity. Our studies aim to pharmacologically manipulate polyamine metabolism to correct this imbalance as a therapeutic strategy for SRS. Here we report the repurposing of 2‐difluoromethylornithine (DFMO), an FDA‐approved inhibitor of polyamine biosynthesis, in rebalancing spermidine:spermine ratios in SRS patient cells. Mechanistic in vitro studies demonstrate that, while reducing spermidine biosynthesis, DFMO also stimulates the conversion of spermidine into spermine in hypomorphic SMS cells and induces uptake of exogenous spermine, altogether reducing the aberrant ratios. In a Drosophila SRS model characterized by reduced lifespan, DFMO improves longevity. As nearly all SRS patient mutations are hypomorphic, these studies form a strong foundation for translational studies with significant therapeutic potential.

Published: September 2023

The Ag8SnS6 crystal was synthesized by directly melting a high-purity stoichiometric mixture of elementary Ag, Sn, and S in a sealed quartz ampoule. This argyrodite crystallizes in the orthorhombic structure (Pna21 space group (No. 33)) at room temperature. The theoretical first-principle calculations of the electronic band structure and density of states of a αʹʹ-Ag8SnS6 crystal are estimated by the generalized gradient approximation (GGA) and local density approximation (LDA). A Perdew–Burke–Ernzerhof functional (PBE) and (PBEsol) were utilized for GGA calculation. All calculated parameters correlate well with known experimental data. Based on the electronic band structure, the effective mass of electrons and holes was calculated. The anisotropic behavior of electronic band structure is discussed.

Holistyczne podejście do pacjenta to wyzwanie, przed którym stoi każda pielęgniarka – niezależnie od tego, czy opieka dotyczy pacjenta w oddziale zabiegowym, czy na bloku operacyjnym. W swoich działaniach pielęgniarskich, w wieloaspektowej i wysoce specjalistycznej opiece nad pacjentem należy dążyć do eliminowania bądź zminimalizowania wywołanych przez chorobę obaw, lęków czy niepokoju, z którymi mierzy się pacjent. Pacjenci mają prawo oczekiwać bezpieczeństwa i ochrony podczas udzielania świadczeń zdrowotnych. Istotną rolę w ocenie bezpieczeństwa pełnią pacjenci, których powinno się edukować i stwarzać możliwość przekazywania informacji zwrotnej, która przyczyni się do poprawy procesu znieczulenia. Istotne jest zapewnienie komfortu pacjentowi poprzez stworzenie dla niego przyjaznej atmosfery, zapewnienie komfortu psychicznego i fizycznego, zapewnienie poczucia godności i intymności, m.in. przez okrywanie nagiego ciała pacjenta, zarówno na sali operacyjnej, jak i poza salą, a także przy przekładaniu pacjenta. Powinno się podejmować działania mające na celu uspokojenie pacjenta bądź starać się odwrócić jego uwagę od problemu. Bezpieczeństwo pacjenta jest integralnym elementem systemu opieki, zależy od kompetencji personelu, a także postaw, poglądów i wzorów zachowań. Nowoczesne pielęgniarstwo dąży do zapewnienia pacjentowi bezpieczeństwa poprzez działania zmierzające ku minimalizacji wystąpienia zdarzeń niepożądanych.
Predicting prices of case furniture products using web mining techniques
Authors: Bardak Timucin
Published: September 2023

This article presents a methodology based on web mining techniques for estimating furniture prices using e-commerce data. Data on different public e-commerce sites in the United States were collected and analyzed using web mining methods. Deep learning and random forest algorithms were used to predict the prices of different types of furniture. Bookcase and dresser type furniture, which are widely used in price estimation, were selected. The inquiry identified a collection of eight distinctive attributes linked to furniture items, spanning measurements such as width, depth, and height, alongside features encompassing frame material, partition count, drawer count, color, and price. In preparation for constructing predictive models, a dataset comprising 300 instances was compiled for comprehensive analysis. Models developed based on web mining to predict furniture prices gave satisfactory results. During the testing phase, the random forest algorithm outperformed deep learning, achieving high goodness of fit values of 0.89 and 0.94 for bookcase and dresser furniture, respectively. The results indicate that price estimation for dresser furniture was more accurate than for bookcases in all models. The findings demonstrate that web mining techniques can be used effectively in competitive furniture pricing, with potential to save time and cost in pricing for furniture purchasing.

Authors: Pokaad Alif Zulfakar , Zainordin Ahmad Zaifazlin
Published: September 2023

The objective of this project is to get the energy absorption of aluminium honeycomb core through experimental work and simulation analysis. The force-displacement behavior and energy absorb are studied for two different cell sizes of honeycomb core, which are 0.0127 m and 0.01905 m, respectively. The out-of-plane dynamic compression tests are conducted for the specimens by using INSTRON CEAST 9340 drop tower machine with an impact mass of 25 kg at 800 mm height and generate an impact velocity of 3.96 m/s. The linear elastic regime, flat plateau force regime and densification regime are observed in the force-displacement behavior in the crushing of aluminium honeycomb core. In finite element simulation, the model of honeycomb structures with 0.0127 m cell size is created in ABAQUS 6.12 in explicit environment. Several parameters such as mesh sizes, time intervals and plasticity models with Isotropic hardening and Johnson-Cook hardening are investigated in the simulation and validated with the experimental results. Isotropic plasticity model with 1 mm mesh size and 500-time interval is the optimum parameters in modelling aluminium honeycomb core with 0.0127 m cell size where the buckling mode of the specimen is similar with the experimental work.

Published: September 2023

Fake news and misinformation are prevalent on the Internet in this day and age. The popularity of social media such as Facebook, Instagram, TikTok has encouraged the people to share news or information over Internet without knowing whether it is a truth or fake information. The outbreak of COVID-19 affected the social activities of all levels of society as people were asked to stay at home to self-quarantine. It indirectly encourages the growth of the social activities online. Even though COVID- 19 is no longer a big threat to the world, people already used to rely on the Internet for the daily activities. Therefore, the trustworthy of the information on the Internet is getting crucial. ETHERST is a blockchain- based PKI that implemented rewarding and punishment mechanism using Ethereum ECR-20 token named PKIToken to improve the trustworthiness of information published by the blockchain nodes. In this paper, we implement an Ethereum-based distributed application (dapp) that allowed the community members to act on trusting and untrusting on information provided by any of the members. With the ETHERST framework as the backend, the ETHERSTWEB is equipped with the rewarding and punishment mechanism to keep the community from misusing the trusting and untrusting action to maintain the trustworthiness of information of a member. With the PKIToken amount level implemented in the backend, it provides an index to the trustworthiness of a member in the community. It has the advantages over the existing rating or review systems that are commonly implemented in many traditional web applications.
A Comprehensive Review of 3D Laser Scanning Point Cloud Data Processing Techniques: Assessing the Dominant Focus and Exploring 3D Modeling and Data Optimization
Authors: Duan Ke , Niguidula Jasmin D , Hou Bang
Published: September 2023

Three-dimensional laser scanning technology primarily relies on dense scanning points to collect vectorized information of the target object and perform point cloud data processing without physical contact. There are numerous case studies in various fields regarding the use of three-dimensional laser scanning technology for point cloud data acquisition of different objects. By utilizing a three-dimensional laser scanner, precise three-dimensional data of the object's surface can be obtained, effectively meeting the high-precision measurement requirements of three-dimensional points on the object. The main objective of this study is to determine the most suitable point cloud processing method for preprocessing the solid obtained through laser-based 3D scanning. To achieve this goal, we systematically reviewed and reported the technical papers discussing/proposing point cloud data acquisition and processing techniques based on 3D laser scanning technology. As a result of our search, we collected 31 papers on this topic. In this report, we present the process of data collection, result analysis, and classification of related studies. The classification is based on the applicability of methods in processing point cloud data using 3D laser scanning technology. The proposed research clearly demonstrates the latest approaches in data processing in this field and highlights areas that remain unexplored, providing potential avenues for further research.

By examining the air traffic of each successful flight from departure to arrival, valuable insights into the aviation industry's perseverance throughout the pandemic are generated. Preliminary findings reveal a sharp decline in air traffic volume by -58.68% in 2020 compared to the previous year, attributed to the significant number of COVID-19 cases reported by December 31, 2020 (totaling 19,892,098 cases). However, the deployment of vaccination doses in 2021 has resulted in a modest recovery, with air traffic volume increasing by 12.64% compared to 2020. This recovery has prompted several countries to cautiously reopen borders and transition towards the recovery phases of the pandemic, despite the ongoing prevalence of COVID-19 cases. The research provides insights into the resilience and adaptability of the aviation industry, shedding light on the challenges faced and opportunities presented during the COVID-19 pandemic. By understanding the impact of social measures and vaccination requirements, stakeholders in the aviation sector can formulate strategies to navigate the current crisis and prepare for potential future disruptions. The findings contribute to the sustainable recovery of the aviation industry by informing policymakers, airlines, and other stakeholders about the factors influencing air travel in the Asian region. The analysis of air traffic, COVID-19 cases, vaccination rates, and social measures provides a comprehensive understanding of the aviation industry's response to the pandemic.

Most Malaysians prefer public transportation as their primary choice for working, returning to their hometown, or traveling from state to state. Due to the rapid development of the Internet, bus tickets can be bought online. However, a passenger who purchased the bus ticket still needs to queue up to get the physical bus ticket, which is time-consuming and increases the risk of virus infection during the pandemic. If the passenger loses his physical tickets, the information may be leaked and exploited. This paper is designed to allow a passenger to book tickets online, where the bus ticket is presented as a QR code. The QR code ticket is auto-generated after the booking is completed. Hence, the passenger can skip queueing at the counter to get the physical ticket, reduce the virus infection and save waiting time. Besides, a cryptographic mechanism is applied in the QR code ticket, which prevents the leakage of QR code information. When the passenger scans the QR code ticket, the system decrypts the protection layer of the QR code ticket and automatically records the passenger's presence in the proposed system.

Published: September 2023

This study aims to present the unique product of the International Chamber of Commerce for dispute resolution in the area of trade finance, namely Documentary Instruments Dispute Resolution Expertise (DOCDEX). The ICC Banking Commission, together with ICC International Court of Arbitration, has designed these distinct set of rules for documentary credit issues, specifically adapted to resolve disputes over interpretation and monitoring of documentary credit implementations. The DOCDEX took effect in 1997 and was reviewed with effect from 2002. According to the DOCDEX, the ICC will engage independent experts who will make their decision. This decision will be considered by the ICC Banking Commission’s technical adviser to ensure that it is in line with the other opinions of the ICC. The decision will be made on the basis of the material provided by the parties, including their arguments. The study discusses the functioning of the DOCDEX Rules, how a DOCDEX decision is made and what law is applicable on the system. Moreover, attention is devoted to an exploration of the difference between DOCDEX system and arbitration. Lastly, the study found that the DOCDEX decision is not binding on the parties but can even more likely be used as evidence if the dispute is referred to a court or an arbitration tribunal.

Biodiesel emerges as a viable option to replace fossil fuels, but the traditional process for the production of biodiesel requires a large energy expenditure, since transesterification has a slow conversion due to the immiscibility of alcohol and oil. On the other hand, with the hydrodynamic cavitation method, a shorter conversion time can be achieved with a high yield; however, there are few studies related to this method. Therefore, the objective of this article is to analyze information from different scientific publications to compare and visualize the parameters used to obtain biodiesel by means of a hydrodynamic cavitation reactor. For this reason, a bibliometric analysis and a systematic review based on the PRISMA method were carried out. In this sense, the relevant articles were selected from the Web of Science, Scopus and Google Scholar databases published between January 2018 and July 2023.Finally, the values of biodiesel yield efficiency were obtained by analyzing the different operating parameters and the different feedstock sources for its elaboration in the hydrodynamic cavitation reactors and comparing their results with international standards. American Society for Testing and Materials (ASTM) D6751 y European Committee for Standardization(EN)14214. It is concluded that hydrodynamic cavitation produces biodiesel that meets international standards and that the highest yields in biodiesel production in most studies have temperature ranges between 50 to 65°C, alcohol: oil molar ratio of 6:1, and methanol is the most used in tranasesterification.
