Authors: Mor Nuriel Sahlom
Published: May 2024

The Vision Transformer (ViT) architecture utilized the self attention and transformer architecture originally designed for natural lan guage processing (NLP) enables ViTs to capture global relationships and long-range dependencies within images. The purpose of our study was to compare the performance of embeddings generated by Convolutional Neural Network (CNN) and Vision Transformers (ViT) on a novel domain-specific task which was not presented at any point to the models prior to the process of the embeddings generation. The pretrained CNN model was MobileNetV2, and the pretrained vision transformer was ViT-B16. The accuracy and F score obtained from the embeddings generated by MobileNetV2 were 0.64 and 0.69 respectively. The accuracy and F-score obtained from the embed dings generated by ViT-B16 were 0.81 and 0.79 respectively. Our study suggests that ViT might perform better in unseen domain specific problems which were not presented in the pretraining. ViT utilizing the self-attention mechanisms capture rich and generic visual representations that might gen eralize well to unseen domain specific problems.

Authors: Suprapto Wahyono , Risonarta Victor Yuardi , Widodo Agung Sugeng
Published: May 2024

Aluminium whose Silicon as its main alloying element, i.e. Silumin, is widely applied in engineering due to its novel properties. For particular application, e.g. as block engine of seawater vessel, Silumin’s properties must be enhanced, e.g. strength at elevated temperature, hardenability and corrosion resistance. For those purposes, Nickel and Copper is added to Silumin in this work. As a result, Copper addition by 4.1 %wt increases Silumin density by 13.9 % from 2.95 to 3.36 g/cm3, decreases grain size by 35.3 % from 39.4 to 25.5 μm, increases hardness by 178.8 % from 21.66 to 60.38 HR30T and increases the corrosion rate by 24.5 % from 0.354 to 0.441 mmpy. Meanwhile, addition of Nickel by 6.35 %wt increases Silumin density by 14.9 % from 2.95 to 3.39 g/cm3, decreases grain size by 29.7 % from 39.4 to 27.7 μm, increases hardness by 161.8 % from 21.66 to 56.71 HR30T and decreases the corrosion rate by 41.2 % from 0.354 to 0.2211 mmpy.
To investigate the influence of Copper and Nickel addition on Silumin’s microstructure, micrograph is also taken by using an optical microscope and a scanning electron microscope. The micrograph shows dendrite presence only for the case of Copper added Silumin which deleterious for mechanical properties of Silumin. This dendrite is predicted due to slower cooling rate of the cast Silumin after Copper addition. In addition, the needle-like β-precipitate is sharper after Copper addition. This circumstance is responsible for higher hardness increase for the case of Copper addition compared to Nickel addition. The micrograph shows the existence of CuAl2 intermetallic phase. This intermetallic phase is nobler than Aluminium which is responsible for higher galvanic corrosion in Silumin after Copper addition. On the other hand, the dendrite cannot be observed in the case of Silumin after Nickel addition. The intermetallic phases after Nickel addition, i.e. AlxNiy contribute to the hardness increase. These phases also remain stable at elevated temperature which then then contributes to better mechanical properties of Silumin at the elevated temperature

Published: May 2024

In this study, an online monitoring system was implemented for the operational control of an industrial-scale steam generation system. The proposed system allows the migration from measuring boiler efficiency under stationary conditions to measuring it under seasonal conditions, providing greater opportunities for improvement in energy performance. For this purpose, a baseline and goal line model of energy consumption as a function of steam production for an operational base period was constructed. The study shows that the steam generation process has a consumption rate of 0.0885 m3/kg, which is associated with boiler technology, fuel quality, insulation condition, heat recovery equipment, among others. In addition, there is evidence of non-production consumption of 41.225 m3/h, which is mainly due to average consumption in non-productive maneuvers such as starting, stopping, and searching for an operating regime in response to changes in steam demand. The correlation between gas consumption and steam generation was 86.4 %, which represents a 13.6 % variability of consumption associated with controllable operational variables with opportunity for adjustment. The monitoring and control of the main operating parameters of the boiler allows an economic savings of 3.13 % in the boiler, which implies a reduction in operating costs of 92,843 USD per year. The analysis of the operational parameters indicates that it is necessary to maintain a feed water temperature higher than 65 °C and a flue gas temperature lower than 214 °C to ensure boiler efficiency higher than 80 %. With the implementation of activities focused on reducing the combustion gas temperature, increasing the feed water temperature, and controlling operational variables, a 9.01 % reduction in the boiler's natural gas consumption was achieved because of the implementation of operational control
Research on the influence of dynamic parameters on the operation process of gantry cranes with assembled structures on the cap of bridge pier to serve installation of Super –T beams
Authors: Bui Thanh Danh , Nguyen Van Cuong , Nguyen Van Vinh
Published: May 2024

The gantry crane, positioned atop the bridge pier cap for the installation of Super-T girders, is a specialized construction unit within the bridge construction industry. The article presents a summary of research results investigating dynamic parameters and their influence on the operation of gantry cranes with assembled structures on the cap of bridge piers, serving the installation of Super-T beams in two scenarios: lifting with pre-stressed cable and moving with load (Super-T beam). To examine the dynamic parameters affecting the operation of the gantry crane, the authors first constructed a dynamic model. Subsequently, the influential parameters were determined, and the Matlab Simulink software was employed to develop a survey model corresponding to different values of each parameter and under various working conditions of the gantry crane. This process aimed to identify patterns and unfavorable values of these parameters affecting the operation of the gantry crane. The research results revealed that in both scenarios of lifting with pre-stressed cable and moving with a load (loading), factors such as lifting speed (Vn), stiffness of the main steel structure (S3), conversion stiffness of the lifting cable (S1), oscillation mass of the main structure (m3), wind load acting on the beam (Pg2), wind load acting on the main steel structure (Pg1), and stiffness of the hanging cable (S1) significantly influence the operation of the gantry crane. The survey results also indicated reasonable values for these influential factors during the operation of the gantry crane. The obtained research results can serve as a basis for computational design problems and effective utilization of gantry cranes with assembled structures on the cap of bridge piers for the installation of Super-T beams. Through analysis and simulation using Matlab-Simulink software, specific data on cable tension, main structure acceleration, and structural deformation were collected. The results emphasize the importance of limiting the lifting speed to 2 m/min to ensure stability during cable tensioned lifting and restricting the crane's moving speed to 7.85 m/min to maintain safety and performance when moving loads with tensioned cables
Comparison of the accuracy of OES and EDX tests on nickel dissolving in brass casting

Published: May 2024

Brass alloys contain the dangerous element lead. Material engineering is carried out to reduce the lead element in brass alloys and add nickel elements as a substitute for lead elements by the casting process. The phenomenon analyzed in this study explains comparing the accuracy level of OES and EDX test results on nickel dissolution in brass casting, especially in adding nickel elements. So that researchers can compare the decrease in the percentage of nickel element composition in the OES test results. At the same time, there is an increase in nickel element composition in the EDX test results. The brass dissolution process uses an electric furnace with an initial temperature of 526 °C. Elemental nickel was introduced into brass solution and dissolved elemental nickel at 978 °C for 120 min for a variation of 1 %, 2 %, 3 %, and for 180 min for a variation of 4 %. The composition of alloying elements is tested using OES and EDX. The dissolution process of brass with the addition of nickel elements tested with OES decreased from 1 % nickel elements to 0.650 %, 2 % to 1.630 %, 3 % to 2.046 %, and 4 % to 2.810 %.
Meanwhile, from the EDX test results, there was an increase in the composition of nickel elements from nickel 1 % to 1.41 %, 2 % to 2.57 %, 3 % to 3.41 %, and 4 % to 4.49 %. Brass alloys with nickel elements added decreased due to slag produced during the dissolution process of nickel elements in molten brass from the test results using OES. EDX testing results in an increase in the percentage of nickel elemental composition. The results of the OES test validation of the mechanical properties of adding nickel elements to brass alloys can be considered because the material's strength is still under the reference UNS C89550. This research contribution resulted in an effective and efficient test method with OES to analyze the elemental composition in brass alloys to which nickel elements have been added

This article presents a method of designing an optimal Proportional-Integral-Derivative (PID) controller for Automatic Generation Control (AGC) of a two-area interconnected thermal system. In addition, an application of Salp Swarm Algirithm (SSA) in order to design PID controllers is proposed. A method inspired by salp foraging behavior. The journey of the Salp group in the sea, by random the population of the salp and separated into leader salp and follower salp. The leader moves towards the food source and the rest of the followers follow the salp positioned in front of themselves. The parameters of PID were achieved by trial and error methods by designers. As an interconneted thermal power system with a Governor Deadband (GDB) is nonlinear and dynamic system, the Integral Squared Error (ISE) criterion has been used as objective function to find optimum controller gain. In order to solve this problem, SSA is proposed to concurrently tune PID gains of the PID controllers to minimize frequency deviations and tie-line power deviations by simulation the interconnected thermal power system .Compare of tuning PID controller from each optimization technique SSA and PSO .Simulation results clearly show that the performance of the system after taking SLP into the interconnected thermal power system that tuning by SSA and PSO and the robustness of the optimal PID controllers are superior to the conventional PID controllers in terms of settling time (–10.46 % in area 1, +0.87 % in area 2 and +0.57 % in power tie-line), overshoot (–10.61 % in area 1 and –10.87 % in area 2) that obtain by (SSA) method less value than the value that obtain by (PSO) method and the power tie-line. Integral Absolute Error (IAE) (–0.38 %) that obtain by (SSA) few errors. Comparisons to the tuned with Particle Swarm Optimization (PSO) approaches is also included

The article outlines the possibility of achieving a comprehensive solution to environmental problems, specifically by neutralizing toxic carbon monoxide and treating wastewater generated during metallurgical production. The use of spent iron sulfate-containing etching solutions allows the creation of effective and affordable manganese-ferrite catalyst systems on a zeolite carrier. The novelty of the study is the use of "green" chemicals – ferrates that include iron (VI) and have great potential in environmentally friendly water treatment technologies. The use of potassium ferrate reduces the need for an alkaline reagent to produce a ferritic material. Confirmation of the composition of the main elements of catalysts was carried out using qualitative X-ray phase and micro-X-ray spectral analysis. The use of an innovative manganese-ferrite catalyst to neutralize carbon monoxide obtained using potassium ferrate provides a successful solution to the problem of toxic gas emission in electrode manufacturing technology and creates pathways for the transition to a circular economy. The cost-effectiveness and environmental friendliness of using the proposed catalyst on a zeolites carrier in a reactor located in the fire channels of the chambers of the Riedhammer multi-chamber furnaces for burning electrode blanks are demonstrated. The preparation of a catalyst from spent sorbents for purifying manganese-containing natural water emphasizes its sustainable nature and contribution to solving environmental problems in the context of production processes. The safety of burial or storage in landfills of ferritic sludge sediments as an analog of magnetite distributed in the earth's crust further emphasizes the importance of the proposed method
Limitations and Innovative Application Methods of Surfactants for
Solubilization of Poorly Water-Soluble Drugs
Authors: Jin Gang , Wang Jie , Xu Jie , Jin Qing , Xue Jian-Fei , Li Lin-Han
Published: May 2024

Poor solubility of drugs leads to poor bioavailability and therapeutic efficiency. A large
proportion of drugs that are not developed and marketed for use by patients are due to their extremely
low solubility. Therefore, improving the solubility of poorly water-soluble drugs is one of the most
important aspects of the field of drug research. With the continuous development of more and more
formulation techniques and excipient applications, the solubility of poorly water-soluble drugs can be
improved to a certain extent to obtain better pharmacokinetics and pharmacodynamics, including pH
microenvironment regulation technology, inclusion complex, solid dispersion, nanotechnology, and
application of surfactants. However, the most widely used among them is the application of surfactants.
This technique can reduce the surface tension, improve wettability, and have a remarkable
solubilizing ability after forming micelles. However, surfactants have also been found to possess
certain limitations in solubilization. In this review, the factors affecting the solubilization of surfactants
and limiting their application have been summarized from several aspects. These factors include
drugs, additives, and media. Some ideas to solve these application limitations have also been
put forward, which can lay a foundation for the wider application of surfactants in the future.
Plant-derived Molecules as Potent Anti-skin Cancer Agents
Authors: Gupta Babita , Malviya Rishabha , Mishra Prem Shankar , Uniyal Prerna
Published: May 2024

The skin is the major tissue in the body and serves as a barrier against hazardous substances
and external attacks. The accumulation of these stressful experiences increases skin cancer risk. In
the United States, skin cancer is a serious health issue. There is a lack of medications that can effectively
treat skin malignancies. In addition, the existing medicines all come with harmful side effects.
Consequently, there is an immediate need for skin cancer treatments that have fewer negative effects.
The preventative possible, therapeutic benefits, bioavailability, and structure-activity relationship of
these chosen phytochemicals for the treatment of skin cancer are discussed in the review. Many cancer
treatments have their origins in the ocean, bacteria, or plants. Cutaneous malignant melanoma has
the highest death rate of all skin cancers and is the most aggressive type of the disease. There are several
ways to treat malignant melanoma; however, they all have very poor success rates because of the
emergence of multi-drug resistance. Phytochemicals are an alternate therapy approach that is both
easily accessible and affordable. Plant-derived phytoconstituents offer a promising anti-carcinogenic
potential for tumors connected to the skin because of their widespread acceptability, safety, fewer
side effects, and signal transmission routes that can be targeted in more than one way. Skin malignancies
are a substantial cause of morbidity and death in the modern world, and research on novel phytochemicals
for their potential to prevent and treat skin cancers has increased dramatically as a result.
The antitumor effect of plant-derived medicinal substances can be attributed to several different
mechanisms and routes, including the breakdown of mitochondrial membrane potential. This review
aimed to provide a concise overview of naturally occurring chemical compounds that are currently
utilized in cancer chemotherapies or have demonstrated potential in avoiding melanoma or skin cancer.
The overview encompasses a variety of phytochemicals, such as flavonoids, carotenoids, terpenoids,
selected polyphenols, and crude plant extracts.

Published: May 2024

Microalgae technology has made significant advances in recent decades.
Initially, Microalgae attracted the interest and attention of the scientific community as a
renewable resource for biofuels. Besides, it also has the potential to accumulate lipids
and biomass significantly in a short period. Recent studies have shown that
microalgae's bioactive peptide could be well-suited with great potential in human
nutritional support. Therefore, a bioactive peptide derived from various strains of
microalgae could be a potentially significant source for developing novel nutraceuticals
and functional foods that can reduce the risk of cardiovascular disease, cancer, and
arteriosclerosis. The bioactive peptide has also been used in anti-wrinkle and anti-aging
skincare products, where it serves to stimulate the creation of proteins in the skin.
Although some microalgae have reported antimicrobial and antivirus peptides, the
understanding of peptides with these properties is still unclear and not described.
Interest in microalgae-derived peptides is overgrowing. This review highlights and
discusses the cutting-edge features of their research and applications to develop new
therapeutic drugs, cosmetics, and other valuable products. It is also exploring the
technology for microalgae peptide extraction and purification.

Relationship between personality traits, reading tendencies, and empathy
Authors: Buljan Terezija , Mlačić Boris
Published: May 2024

Literature suggests that reading fiction, more than reading nonfiction, correlates positively with the reader's social cognition, chiefly cognitive empathy. Earlier studies also indicate that individual differences, especially personality traits, are relevant predictors of reading tendencies that should be considered while studying the relationship between empathy and reading. Hence, in this study we examined whether personality traits, gender, and the students' fiction and nonfiction reading tendencies predict affective and cognitive empathy. University students (N = 429) participated in this study using the following questionnaires: The Emotional Empathy and Fantasy Scale (Raboteg-Šarić, 2002), the IPIP-50 Big-Five markers (Mlačić & Goldberg, 2007), and a newly constructed reading tendencies questionnaire. The results of multiple regression analyses indicate that Big Five Intellect and Big Five Emotional stability positively predicted nonfiction-reading tendency. Moreover, Intellect, Agreeableness, and gender (female) positively predicted fiction-reading tendency, while Extraversion was a negative predictor. Also, Intellect, Agreeableness, gender (female) and fiction-reading tendency positively predicted cognitive empathy. Agreeableness and gender (female) were positive, while Emotional stability and Extraversion were negative predictors of affective empathy.

The author reviews the importance of using management information systems in implementing and achieving efficient and effective learning. The role of technology is currently seen as helping systematic work. Technology can function to realize learning in a laboratory that is independent and better. Technology in the form of a learning management information system is expected to help students learn independently. The management information system is a means of monitoring laboratories' use, especially in the Department of Automotive Engineering Education. The conclusions obtained include: (1) the management information system is seen as helping educational institutions as a means of learning practicum in an independent laboratory, (2) supporting the management of laboratory facilities, (3) recording and distributing information appropriately, and (4) as a means of supporting operations another technical. In practice, SIM laboratory learning can be constrained by: (1) human resource competence and (2) an adequate level of technology.

BACKGROUND

Frequently lacking immediate access to care providers, pregnant individuals often seek information online to address their evolving physical and mental health needs.

OBJECTIVE

Given social media’s increasing prominence as a source of news and information, this study investigated the extent to which patients may be willing to disclose personal health information to social media companies in order to obtain personalized health content.

METHODS

We designed and deployed a survey to pregnant patients worldwide electronically in 2023. We utilized the classical Internet Users' Information Privacy Concerns (IUIPC) model to examine how privacy concerns modulate pregnant individuals’ behaviors and beliefs about risk and trust while using social media for health purposes.

RESULTS

Among 317 respondents who initiated the survey, 265 respondents remained in the study providing complete responses. Among them, 55% indicated willingness to provide their personalized health information in exchange to receiving personalized health content via social media, while 26% were uncertain and 19% opposed. Parallel to pregnant individuals’ willingness to share, we find that they have more heightened privacy concerns and their use of social media for information seeking is largely impacted by their trust with the platforms. Our estimated IUIPC model results are statistically significant and qualitatively align with the classic IUIPC model for the general population previously found in an e-commerce context.

CONCLUSIONS

We find that more than half of the pregnant individuals are open to sharing their personal health information to receive personalized content about health via social media, although they have more privacy concerns than the general population. This study emphasizes a needed policy around protection of health data on social media for the pregnancy population and beyond.

BACKGROUND

The use of unsupervised, app-based cognitive assessments provides considerable opportunities for early and comprehensive testing for Alzheimer’s disease, minimizing the demand on time and personnel resources in medical practices. However, the acceptance of such an app within healthcare has yet to be assessed.

OBJECTIVE

In this pilot study, we examined the acceptance of an app-based, repeated cognitive assessment for early symptoms of Alzheimer’s disease (neotivCare) in the outpatient care setting from both physicians’ and patients’ perspectives.

METHODS

Fifteen primary care practices participated, where patients with self- or relative-reported memory problems could be prescribed an app for comprehensive cognitive testing. Patients used the app to test their episodic memory function weekly for three months at home. After the testing period and the final consultation, physicians and patients received questionnaires to assess the app’s acceptance.

RESULTS

We received completed questionnaires from physicians for 45 patients. Additionally, we received 45 completed questionnaires from the patients themselves. The physicians reported that, for most patients, the app supported their decision-making in the diagnostic process (58%). Additionally, most physicians found the app’s information dependable (75%) and felt more certain in their decisions (84%). From the patients’ perspective, a majority felt thoroughly tested (76%), and only a few considered the time commitment for the cognitive tests to be too burdensome (15%). Moreover, despite the weekly cognitive testing and the lengthy twelve-week testing period, a majority of patients participated in all tests (72%).

CONCLUSIONS

Our pilot study indicates a high acceptance of an app for unsupervised, app-based cognitive testing over an extended period from both the participating physicians’ and patients’ perspectives. These initial findings suggest that unsupervised app-based cognitive assessment can be integrated into healthcare.
