BACKGROUND

Transforming growth factor-β (TGF-β) superfamily plays an important role in tumor progression and metastasis. Activin A receptor type 1C (ACVR1C) is a TGF-β type I receptor that is involved in tumorigenesis through binding to different ligands.

AIM

To evaluate the correlation between single nucleotide polymorphisms (SNPs) of ACVR1C and susceptibility to esophageal squamous cell carcinoma (ESCC) in Chinese Han population.

METHODS

In this hospital-based cohort study, 1043 ESCC patients and 1143 healthy controls were enrolled. Five SNPs (rs4664229, rs4556933, rs77886248, rs77263459, rs6734630) of ACVR1C were assessed by the ligation detection reaction method. Hardy-Weinberg equilibrium test, genetic model analysis, stratified analysis, linkage disequilibrium test, and haplotype analysis were conducted.

RESULTS

Participants carrying ACVR1C rs4556933 GA mutant had significantly decreased risk of ESCC, and those with rs77886248 TA mutant were related with higher risk, especially in older male smokers. In the haplotype analysis, ACVR1C Trs4664229Ars4556933Trs77886248Crs77263459Ars6734630 increased risk of ESCC, while Trs4664229Grs4556933Trs77886248Crs77263459Ars6734630 was associated with lower susceptibility to ESCC.

CONCLUSION

ACVR1C rs4556933 and rs77886248 SNPs were associated with the susceptibility to ESCC, which could provide a potential target for early diagnosis and treatment of ESCC in Chinese Han population.
A Novel Friction Mean Effective Pressure Model for a Heavy-Duty
Diesel Engine by Neural Network and Its Applications to Heat Release Rate
Profile Optimization
Authors: Yamaguchi Takuya , Uchida Noboru , Watanabe Kazumasa , Hattori Yuki
Published: December 2024

The prediction of friction mean effective pressure (FMEP) is important when
engine performance is estimated in the model-based development process. The
Chen–Flynn model as a function of the maximum in-cylinder pressure
(Pmax) and mean piston speed (Cm) is often used to
predict FMEP because of its simplicity to utilize; however, this study inferred
from the results of multiple regression analysis between FMEP and factors
related to combustion phase and rate of heat release profile (ROHR) that the
Chen–Flynn model may be difficult to accurately estimate FMEP in a modern diesel
engine with common rail fuel injection system, which allows the control of fuel
injection pressure (Pinj) and combustion phase. In this study, a
neural network with machine learning was applied to predict FMEP based on the
expectation that the ROHR profile, which allows the reduction of FMEP may be
possible to be found. 7666 points experimental results that include FMEP and
combustion parameters in the heavy-duty single-cylinder diesel engine were
utilized as training and validation data for machine learning. The pre-trained
neural network prediction model for FMEP can predict the tendency of FMEP better
than the Chen–Flynn model when start of combustion (SOC) and Pinj
were varied. The error between the predicted FMEP results by the pre-trained
neural network and the experimental results of FMEP were within 4% of the
experimental results when SOC was advanced from top dead center to −7 deg. ATDC.
Whereas, the predicted FMEP by Chen-–Flynn model had a maximum error of 15%
compare to the experimental results. Furthermore, the predicted FMEP by
Chen–Flynn model had a maximum error of 9% compare to the experimental results
when Pinj was varied from 120 MPa to 200 MPa, whereas the error
between the predicted FMEP results by the pre-trained neural network and the
experimental results of FMEP were within 4% of the experimental results. The
pre-trained neural network model was confirmed to be predictive better than the
Chen–Flynn under the conditions that the combustion phase and Pinj
are changing. In addition, the parameter study using the pre-trained neural
network prediction model for FMEP and a one-dimensional engine performance
simulation tool was conducted to find the ideal ROHR profile that improve brake
thermal efficiency (BTE). The result of parameter study suggests that the
optimum ROHR profile to improve BTE under the same conditions of Pmax
and the degree of constant volume combustion is to shorten combustion duration
and to retard the peak of ROHR away from top dead center.
Enhancing Engine Cooling Efficiency: Evaluating Zinc & Magnesium
Oxide Nanofluid Viscosity
Authors: Manikandan S. , Vickram A. S. , Madhu S. , Saravanan A.
Published: December 2024

In this study, the viscosity and thermal performance of nanofluids based on
ZnO-MgO mixed oxide nanoparticles added in different concentrations to ethylene
glycol-water mixture are characterized with potential applications in engine
cooling. The work began with two needs: the increasing importance of better heat
removal in automotive engines, where traditional coolants struggle to adequately
maintain good thermal conductivity but at low viscosity to acceptable levels;
and a chance opportunity for exploration provided by MMD/MILab Engineer Andrew
Cricee. The work wants to improve the cooling properties, but still keeping good
fluidity by integrating ZnO-MgO nanoparticles. Preparation method the
preparation of ZnO-MgO nanofluids was done using volume concentrations of 0.1%,
0.3% and 0.5%. To determine chemical properties, viscosity measurements were
made on the Dragonfly using a Brookfield viscometer at temperatures ranging from
25 ° C to 80 ° C while varying the nanoparticle concentration as well as
temperature. Furthermore, measurements for thermal conductivity were also done
in order to evaluate the heat transfer ability of the nanofluids with reference
to common coolants. Present work is novel in the area of ZnO-MgO mixed oxide
based nanofluids as joint correlation analysis and no such reports are available
in context with automotive cooling systems. The results show that, at higher
nanoparticle loading ratios, the viscosity is increased but as temperature is
elevated, the opposite effect takes place so heat can be dissipated while having
a lower resistance to fluid flow. Thus, with the incorporation of ZnO-MgO
nanofluids as coolants but also their thermal conductivity enhanced at higher
temperatures as well as at higher concentrations, it serves its prime purpose to
replace conventional coolants in an internal combustion engine system allowing
superior performance and longevity of the engine. The present work reports the
potential of ZnO-MgO nanofluids for active engine cooling applications and high
thermal efficiency.

Published: December 2024

In highly populated countries two-wheelers are the most convenient mode of
transportation. But at the same time, these vehicles consume more fuel and
produces emissions in urban driving. This work is aimed at developing a hybrid
two-wheeler for reducing fuel consumption and emissions by incorporating
electric vehicle technology in a conventional two-wheeler. The hybrid electric
scooter (HES) made consisted of an electric hub motor in the front wheel as the
prime mover for the electrical system. The powertrain of the HES was built using
a parallel hybrid structure. The electric system is engaged during startup, low
speeds, and idling, with a simple switch facilitating the transition between
electric and fuel systems. The HES was fabricated and tested through trial runs
in various operating modes. Before conversion to a hybrid system, the
two-wheeler achieved a mileage of 34 km/liter. After conversion, the combined
power sources resulted in an overall mileage of 55 km. It was observed that the
voltage supplied to the motor increases proportionally with speed. The HES model
was developed using MATLAB-Simulink, and simulation results indicated that the
vehicle operates in electric mode at speeds below 20 km/h and switches to an
internal combustion engine above 20 km/h. Operating the HES in electric mode at
speeds below 20 km/h can significantly reduce fuel consumption and emissions,
making it an ideal solution for urban driving in densely populated areas.

Published: December 2024

This study describes the Taguchi optimization process applied to optimize
drilling parameters for glass fiber reinforced composite (GFRC) material. The
machining process is analyzed in relation to process parameters using analysis
of variance (ANOVA). The characteristics assessed for both the drilling and the
specimen include speed, feed rate, drill size, and specimen thickness. The
commercial software program MINITAB14 was used to collect and analyze the
measured results. Cutting force and torque during drilling are examined in
relation to these parameters using an orthogonal array and a signal-to-noise
ratio. The primary goal is to identify the critical elements and combinations of
elements that impact the machining process to achieve minimal cutting thrust and
torque, based on the evaluation of the Taguchi technique.
Influence of Exhaust Gas Recirculation on Emission Metrics in a
Diesel Engine Operated with Hydrogen Induction and
Cassia
fistula
Biodiesel

Published: December 2024

The current study investigates the influence of exhaust gas recirculation
technique on the hydrogen (10lpm) inducted diesel engine using Cassia
fistula derived biodiesel fuel. The focus is on evaluating the
emission characteristics of the engine, with a particular emphasis on reducing
NOx emissions. The study also examines the impact of varying the Exhaust Gas
Recirculation (EGR) flow rate 10 and 20% on the aforementioned parameters. The
novelty of this investigation lies in the comprehensive evaluation of emission
metrics, particularly when combining Cassia fistula biodiesel with hydrogen
induction. The experiment carried in Kirloskar TV1-V4A engine with blends
consists 10%, 20%, 30% and 40% by volume of CFME blends with diesel. The
inducted hydrogen at 10 lpm caused increased NOx which were discussed to
suppress by EGR applications. Among the tested fuels, a blend containing 40%
cassia fistula methyl ester (CFME) and 60% diesel
(CFME40D60) showed the lowest hydrocarbon (HC) emissions, achieving 20 ppm, 18
ppm, and 23 ppm under non-EGR, 10% EGR, and 20% EGR conditions, respectively.
Additionally, the CFME40D60 blend exhibited the lowest carbon monoxide (CO)
emissions, with values of 0.0141%, 0.0156%, and 0.0159% by volume under the same
conditions. The blend also demonstrated superior performance in reducing smoke
opacity, achieving 32%, 32%, and 31% opacity, compared with diesel. Notably, the
NOx emissions were significantly low with CFME10D90 blend, showing values of
1910 ppm, 1801 ppm, and 1598 ppm, with a 312 ppm reduction at the 20% EGR rate
compared to non-EGR conditions. These findings provide insights into optimizing
the fuel mixture and EGR settings to achieve improved engine performance and
reduced emissions, making it a viable option for sustainable transportation.
Evaluation of Waste Transformer Oil Biodiesel Blend with n-Heptane
Additives for Engine Performance under Variable Injection Pressure and
Timing
Authors: Veeraraghavan Sakthimurugan , Palani Kumaran , De Poures Melvin Victor , Madhu S.
Published: December 2024

This study examines performance metrics and emission profiles of Kirloskar TV1 CI
engine fuelled with blend containing waste transformer oil (WTO) biodiesel
(40%), n-Heptane (10%), and diesel (50%) by volume (referred to as WTO40H10D50),
with additional 10 lpm of hydrogen induction in the intake manifold. Effects of
varied injection of fuel timing (19°, 21°, and 23°bTDC) and injection pressure
(170, 210, and 240 bar) of WTO40H10D50 on diesel engine were analyzed at 100%
engine loading condition. The findings indicate that an injection timing of
23°bTDC and an IP of 240 bar yield the highest BTE and lowest BSEC, suggesting
optimal energy conversion efficiency. The influence of inducted H2
resulted in the lowest smoke opacity and HC emissions, demonstrating more
complete and cleaner combustion. The results indicate at 23° bTDC of injection
timing and 240 bar injection pressure produced best overall performance, with
highest brake thermal efficiency and the lowest brake specific energy
consumption, reflecting more efficient energy conversion and fuel use. This
combination also resulted in the lowest smoke opacity, signifying cleaner
combustion with minimal soot emissions. However, for emissions control,
different injection timings performed better: 19° bTDC at 240 bar minimized
unburnt hydrocarbon (UHC) emissions, while 21° bTDC at 240 bar yielded the
lowest carbon monoxide (CO) emissions. The trade-off occurred with oxides of
nitrogen (NOx) emissions, which were highest at 19° bTDC due to elevated
combustion temperatures, requiring after-treatment technologies for mitigation.
Overall, while 23° bTDC and 240 bar yielded the best fuel efficiency and
cleanliness These settings provide a balanced approach, maximizing efficiency
and minimizing harmful emissions, making them suitable for cleaner diesel engine
operation.

Published: December 2024

Purified nickel and a large number of MgTi2 / NiO2
catalysts with various MgTi2 loadings were produced using the
traditional incipient wetness method. X-ray crystallography and
Fourier-transform infrared spectroscopy were used to examine the catalysts. To
understand the material's microstructure better, the researchers investigated
oxygen adsorption at 90K. The amine titration method was used to investigate the
acidic characteristics of these catalysts. In a study on cumene cracking, these
catalysts were employed. The catalyst was found to be amorphous up to a loading
of 12 weight percent MgTi2, but at higher loadings, crystalline
MgTi2 phase formed on an amorphous silica substrate. When
NiO2 is doped with more MgTi2, there are significant
differences in the structure, surface acidity, and catalytic activity of the
catalysts. Catalysts with a higher MgTi2 loading are noticeably more
acidic than those with a lower MgTi2 loading. A correlation between
the amount of cracking activity and the number of acid sites on the catalyst
surface has been shown in numerous studies. Cumene cannot be cracked over the
investigated catalysts unless the catalyst contains extremely acidic sites.
Unmistakably Bronsted acid sites, with the breaking action attributed to a
mechanism involving chromium ions. The results were validated by comparing them
with relevant studies in the existing literature. These comparisons demonstrate
consistency with similar research, confirming the effectiveness of the
MgTi2/NiO2 catalysts.

Strong Nominal Semantics for Fixed-Point Constraints
Authors: Caires-Santos Ali K. , Fernández Maribel , Nantes-Sobrinho Daniele
Published: December 2024

Nominal algebra includes $\alpha$-equality and freshness constraints on nominal terms endowed with a nominal set semantics that facilitates reasoning about languages with binders. Nominal unification is decidable and unitary, however, its extension with equational axioms such as Commutativity (which has a finitary first-order unification type) is no longer finitary unless permutation fixed-point constraints are used. In this paper, we extend the notion of nominal algebra by introducing fixed-point constraints and provide a sound semantics using strong nominal sets. We show, by providing a counter-example, that the class of nominal sets is not a sound denotation for this extended nominal algebra. To recover soundness we propose two different formulations of nominal algebra, one obtained by restricting to a class of fixed-point contexts that are in direct correspondence with freshness contexts and another obtained by using a different set of derivation rules.
Linear Arboreal Categories
Authors: Abramsky Samson , Montacute Yoàv , Shah Nihil
Published: December 2024

Arboreal categories, introduced by Abramsky and Reggio, axiomatise categories with tree-shaped objects. These categories provide a categorical language for formalising behavioural notions such as simulation, bisimulation, and resource-indexing. In this paper, we strengthen the axioms of an arboreal category to exclude `branching' behaviour, obtaining a notion of `linear arboreal category'. We then demonstrate that every arboreal category satisfying a linearisability condition has an associated linear arboreal subcategory related via an adjunction. This identifies the relationship between the pebble-relation comonad, of Montacute and Shah, and the pebbling comonad, of Abramsky, Dawar, and Wang, and generalises it further. As another outcome of this new framework, we obtain a linear variant of the arboreal category for modal logic. By doing so we recover different linear-time equivalences between transition systems as instances of their categorical definitions. We conclude with new preservation and characterisation theorems relating trace inclusion and trace equivalence with different linear fragments of modal logic.

Ebben követi a 2004-ben már az Osiris Kiadónál megjelent kiadvány (Laczkó–Mártonfi 2004: 175−8) főbb típusait. Tanulmányomban az új tulajdonnévi névcsoportba tartozó tárgyneveken belül a magyarországi mozdonyok és mozdonykocsik neveivel foglalkozom. A mozdonynevek között előfordulnak hivatalos nevek, illetve becenevek is. A gőzmozdonyok névadási jellemzői kezdetben egyedi nevek voltak, főként helynevek szerepeltek átvitt névadással, néhány személynév is előfordult. Később, a tömegtermeléssel a hivatalos elnevezés inkább a típus és szám megjelölést részesítette előnyben, ekkor már inkább a becenévadás jellemzőit figyelhetjük meg a mozdonyok nevei között. A mozdonynevek helyesírása követhető az általános helyesírási szabályok szerint.

The Role of Emotional Attachment in the Impact of Generation Z's Trust in Digital Influencers on Unplanned Purchase Behavior
Authors: Ateş Alper , Sunar Halil , Erdem Bilal
Published: December 2024

By 2024, the global Internet user base is expected to reach 5.5 billion, with 94% actively engaging on social media platforms. Marketing managers increasingly employ strategies involving key opinion leaders to connect with Generation Z, a demographic known for its digital fluency and reliance on social networks. This study utilizes a qualitative approach to investigate how emotional attachment impacts Generation Z consumers’ trust in social media figures and its effect on impulsive buying behavior. It contributes to the body of knowledge on digital marketing by identifying factors that enhance the effectiveness of social media personalities in reaching and persuading Generation Z audiences.
The findings provide actionable insights for content creators aiming to expand their following and for businesses seeking to strengthen their credibility and drive consumer purchasing decisions through collaboration with digital creators. The results reveal that emotional attachment to online personalities is a crucial driver of trust among Generation Z, significantly affecting their unplanned purchasing habits. Additionally, emotional connection acts as a catalyst, amplifying the impact of trust on spontaneous buying tendencies.
Although trust in social media figures has a notable effect on unplanned purchasing, the relatively weak correlation underscores the need for further exploration of additional factors influencing Generation Z’s decision-making processes.

Images of I. V. Stalin and A. Hitler in Historical Memory: Constructing the Past in the Media Space
Authors: Artamonov Denis S. , Sidorov Sergei P. , Tikhonova Sophia V.
Published: December 2024

The article is devoted to the consideration of the images of I. Stalin and A. Hitler in historical memory. The construction of ideas about the past is based on the possibilities of media, which in the digital age are becoming limitless. With the help of media, images of the past are integrated into the agenda and actualized in the mass consciousness, and personalized figures of history are most in demand. The historical memory of modern society is largely formed on the basis of ideas about the events and heroes of the 20th century, which include the history of totalitarian regimes and the Second World War. The authors put two key figures of the last century with contradictory historical reputations at the center of their research. The article shows the importance of I. Stalin and A. Hitler for historical memory on the basis of available sociological research data. A corpus analysis of the tonality of news reports mentioning these historical figures allowed us to present the proportions of positive and negative use of their names in foreign media publications. Quantitative data made it possible to compare attitudes towards Stalin and Hitler in English-language information resources and explain certain trends in the dynamics of their representation by the nature of the news content. The study of Internet users’ search queries allowed us to supplement the idea of the directions of constructing images of the Soviet leader and the Nazi Fuhrer in historical memory. The data obtained demonstrate the high interest of the world community in ambiguous historical figures. Their images have become part of popular culture, they are used in political struggle and entertainment network discourse, which leaves an imprint on the formation of ideas about them in the media environment. The use of quantitative analysis data to study the images of I. Stalin and A. Hitler makes it possible to determine their place in the historical memory of the modern global community.
Traumatic Futurism in Computer Games
Authors: Kirichenko Vladislav V.
Published: December 2024

This work is devoted to the issue of traumatic futurism in computer games. This type of game has long become an important element of the everyday culture of many people. That is why it is worth paying special attention to the study of their medial psychological capabilities and mechanisms of influence. In the modern world, games have increasingly begun to address issues of existing problems in the field of politics, society and culture, including periodically related to issues of trauma and disaster, which can be experienced by people both personally and remotely through news or works of art. The concept we use is “traumatic futurism”. It means a special form of medial normalization of the crisis experience that the game subject could experience in his real life. The term is intended to indicate the unique features that gaming simulations and procedures can generate. Throughout the work, we build on the research of various authors who analyzed both the problems of disaster and trauma, as well as various features of the normalization or sedation of difficult real experiences by media. The work presents an analysis of game projects that focus either on the private experience of the traumatic or the collective experience of the catastrophic. In conclusion, different outcomes of traumatic futurism are drawn, which can be considered as a positive therapeutic effect, but also as a sedative, normalizing media factor.
Paws and Posts: Reading Turkish Culture through Storytelling about Istanbul Cats on Instagram**
Authors: Özbek İçten Duygu , Türk Gül Dilek , Kölgelİer Yelda Özlem
Published: December 2024

This study delves into the surge of Turkish cat popularity on social media, particularly in the aftermath of the pandemic. Its primary focus is to investigate the conjecture that Turkish cats have evolved into a tourist magnet, igniting an organic phenomenon of cat tourism in Türkiye.
The study aims to investigate international visitors’ impressions and opinions about Türkiye by analyzing user-generated content on Instagram**, which focuses on Istanbul cats within the context of communication. It also aims to assess how the relationship between Turkish people and stray cats in Türkiye has developed into the iconic image of Turkish cats in the eyes of travelers and their impact on the country’s tourism as a unique attraction for tourists from abroad. Additionally, the study seeks to gauge the impression of Turkish cats as a compelling element for tourists through the lens of international travelers. Utilizing content analysis, 1,393 Instagram** posts tagged “Istanbul cats” were selected for scrutiny, with an analysis of 145,000 comments based on predefined themes and codes. The study concluded that international users mainly developed positive feelings and thoughts toward Istanbul cats, the subjects of storytelling in Instagram** posts, while solidifying their position as a valuable component of cultural attraction. A majority of international users expressed a desire to visit Türkiye or even relocate solely because of cats.

Animal Interface: Digital Design beyond the Humankind
Authors: Ocheretyany Konstantin A.
Published: December 2024

Humankind has always coexisted with other species: its mimetic features and abilities, which include science and art, as well as the graphical user interface that appears at their intersection, express empathy, understanding, premonition, receptivity and adaptation to the complex dynamics of other species, to being among them. At the same time, the interface is considered exclusively as an “anthropological machine,” i.e. as a technical and symbolic representation of the idea of the “absence” of “nature” in man, creating conditions for rupture and isolation with the original factors of mimesis, stirs the need to compensate nature, hypostasis, fantasmatize, stigmatize, etc. — i.e., to think of the experience of nature in terms of a collision with a monster or catastrophe, and to expect salvation from AI, artificial intelligence. Therefore, in order to adequately think through and evaluate interfaces, it is necessary to return to the most “natural” intelligence — mimesis, autopoiesis, biophilia, live communication — it is necessary to give a word to nature, i.e., to take into account the experience of non-human beings, animals, their behavior, communication, dynamics, everything that was considered in the exclusively functional assessment of interfaces rather, “noises,” “interference”. In fact, in order for the interface to express our characteristics, take into account certain aspects of character and behavior, and give us a sense of attention and care, it is necessary that it interact not so much with “pure consciousness” as with our physicality, responding to existential patterns, “deep time” enclosed in our physicality by evolutionary processes, pre-predictive ways of our presence and orientation in reality. We need not only linguistic, neural network, large, etc. data, but also “live” data — for this purpose, the article examines and analyzes the experiences of interaction with animals in interfaces, the features of biophilic information and animalistic design, the participation of animals in the design of interface shells as living environments.
Features of the Politics of Memory in the Caspian Region: The Case of Azerbaijan
Authors: Fedorova Maria M. , Romanova Anna P.
Published: December 2024

In this article, based on the analysis of data from a comprehensive sociological study, the features of the memory policy of the Republic of Azerbaijan were identified in comparison with similar ones in other “post-Soviet” Caspian republics in the context of constructing new national identities. It was concluded that the memory policy of the Republic of Azerbaijan, the “core” of which is the concept of “trauma”, plays an important role in constructing the country’s new national identity. In this case, trauma is represented by a whole complex of memory markers combined with ideas about the genesis of Azerbaijanis’ own national identity in the confrontation with the Armenian people (deportation, wars). These events left a deep mark on the collective memory of the Azerbaijani people, especially due to mass losses, forced displacement, and destruction. The state actively uses the memory of traumatic events to strengthen national identity, to unite the society and to mobilize the nation around the idea of restoring territorial integrity.
Aproximación tipomorfológica a la obra Tientos del Véspero de Alfredo del Mónaco
Authors: Álvarez Acero Daniel Alberto
Published: December 2024

Con la aparición de la música concreta se desarrolló un método de análisis de la percepción de las estructuras sonoras denominado Tipomorfología, el cual consiste en proveer diversos criterios para la clasificación de diferentes parámetros del sonido por su forma y tipo. Dicha metodología tuvo importantes repercusiones en algunos compositores y teóricos que ampliaron su perspectiva; tal es el caso de Lasse Thoren quien a través de la sonología aural reformula y expande algunos conceptos de la tipomorfología schaefferiana para ofrecer un enfoque analítico de la música tal como es oida, cuya perspectiva se centra diversas formas de escucha y de comprensión aplicadas a cualquier tipo de estilo musical. Este enfoque motiva a realizar el análisis tipomorfológico de la obra Tientos del véspero del compositor venezolano Alfredo del Mónaco, quien fuera pionero de la música contemporánea de su país, y en cuyo trabajo se puede vislumbrar algunos criterios tipomorfológicos. En ese sentido, el presente artículo introducirá algunas de las nociones básicas de la tipomorfología a través del trabajo de Thoresen, presentará una semblanza del compositor venezolano referido y expondrá el análisis tipomorfólgico de una de sus obras más importantes para guitarra sola.

Published: December 2024

This study develops an advanced technique for segmenting the gallbladder from dynamic B-mode ultrasound images to enhance the accuracy and efficiency of volumetric analysis in medical diagnostics. Using a Wi-Fi probe, volumetric data are captured and processed into labeled images for training a fully convolutional network (FCN) model with specifications including an epoch of 9, a batch size of 3, and a learning rate of 0.001. Performance metrics such as global accuracy, mean accuracy, and Intersection over Union (IoU) are evaluated. The MobileNetV2 architecture achieves a maximum mean IoU of 0.690 and a mean Boundary F1 (BF) score of 0.990, while the ResNet50 architecture demonstrates significant effectiveness. This study substantiates the effectiveness of the MobileNetV2 architecture for precise gallbladder segmentation in dynamic B-mode ultrasound imaging.
