Background and Purpose The gut hormone glucose-dependent insulinotropic
polypeptide (GIP) signals via the GIP receptor (GIPR) resulting in
postprandial processes such as potentiation of glucose-stimulated
insulin secretion. Translation of results from rodent to human studies
has, however, been challenged by contradictive therapeutic effects of
GIPR-targeting compounds. We, therefore, investigated the variation
between species focusing on GIPR desensitization and the role of the
C-terminus. Experimental Approach Species variants of the GIPR were
studied in vitro for endogenous ligand affinity, G protein
activation (cAMP accumulation), recruitment of beta-arrestin, and
internalization. Variants of the mouse, rat, and human GIPRs with
swapped C-terminal tails were studied in parallel. Key Results The human
GIPR is more prone to internalization than rodent GIPRs. Despite similar
agonist affinities and potencies for G-activation
especially the mouse GIPR has a reduced receptor desensitization,
internalization, and beta-arrestin recruitment. Using an enzyme-stable,
long-acting GIP analogue, the species differences were even more
pronounced. “Tail swapped” human, rat, and mouse GIPRs were all fully
functional in their G-coupling and the mouse GIPR
regained internalization and beta-arrestin 2-recruitment properties with
the human tail while the human GIPR lost the ability to recruit
beta-arrestin 2 when its own C-terminus was replaced by the rat or mouse
tail. Conclusion and Implications Desensitization of the human GIPR is
dependent on the C-terminal tail. The diverse functionality of the
C-terminal tail as well as receptor internalization patterns between
species, especially human and mouse GIPRs, are important factors that
could influence the preclinical therapeutic evaluation of GIPR targeting
compounds.
The Inhibitory Effect of Adenosine on Tumor Adaptive Immunity and Intervention Strategies
Authors: Wang Longsheng , Zhang Jie , Zhang Wenxin , Zheng Mingming , Guo Hongjie , Pan Xiaohui , Yang Bo , Ding Ling
Published: July 2023

Adenosine (Ado), mainly produced by the hydrolysis of ATP, exhibits
significantly elevated levels in the tumor microenvironment (TME)
compared to normal tissues. Upon binding to adenosine receptors (AdoRs),
Ado initiates downstream signaling pathways that suppress tumor antigen
presentation and immune cell activation, thereby inhibiting tumor
adaptive immunity. Ado downregulates major histocompatibility complex II
(MHC II) and co-stimulatory factors expression on DCs and macrophages,
thereby inhibiting antigen presentation to T cells. Ado inhibits the
binding of the T cell receptor (TCR) to its ligand and transmembrane
signal transduction on T cells, thus suppressing anti-tumor cytokines
secretion and inhibiting T cell activation. Ado also inhibits the
secretion of chemokines and the KCa3.1 channel, thereby suppressing the
trafficking and infiltration of effector T cells into the tumor site.
Moreover, Ado inhibits the cytotoxicity of T cells against tumor cells
by promoting the secretion of immune-suppressive cytokines, increasing
the expression of immune checkpoint proteins, and enhancing the activity
of immune-suppressive cells. Due to the inhibitory effects of Ado on
tumor adaptive immunity, reducing Ado production in the TME can exert
significant anti-tumor immune effects and enhance the efficacy of other
immunotherapies. Various inhibitors blocking Ado generation or AdoRs are
now under preclinical or clinical development. Therefore, this article
will summarize and analyze the inhibitory effects and molecular
mechanisms of Ado on tumor adaptive immunity, as well as provide an
overview of the latest advancements in targeting Ado pathways in
anti-tumor immune responses.
Protection scheme against turn to turn fault for novel magnetic valve controllable reactor based on thyristor current distortion
Authors: Zheng Tao , Meng Lingkun , Chen Ying , Qu rongqi
Published: July 2023

Turn to turn short circuit is a common fault of the Magnetic Valve
Controllable Reactor(MVCR), but the current research on the
characteristics of turn to turn faults is not clear. What’s more, the
corresponding protection also has certain limitations. In this paper, a
novel type of MVCR that has been put into operation in engineering is
studied. Firstly, the topology structure of the novel MVCR is
introduced, and the electrical characteristics of its steady-state
operation are analyzed. Based on this, the fault characteristics of the
excitation winding and working winding of the novel MVCR when turn to
turn faults occur are studied. The study shows that when turn to turn
faults occur, the amplitude of DC and AC component in the thyristor
current both increase significantly, resulting in large current
distortion. Due to the fault characteristics, this paper introduces the
current distortion coefficient to quantitatively analyze the different
characteristics of the two components before and after the faults.
Furthermore, a protection scheme against turn to turn fault based on the
thyristor current distortion is proposed. Finally, the feasibility and
effectiveness of the proposed turn to turn protection scheme are
verified by Matlab/Simulink simulation experiments.
Developing a quantitative measure of social privilege to inform the design of blockchain governance mechanisms and voting systems
Authors: Velpanur Nikhil
Published: July 2023

This paper proposes a novel voting system that incorporates an
intersectional Privilege Index to address social inequalities and power
imbalances that often lead to marginalized groups being underrepresented
in the political sphere. The Privilege Index is a composite measure that
takes into account various factors, such as race, gender, socioeconomic
status, and education, which contribute to an individual’s social
privilege. By incorporating this index into the voting process, the
proposed blockchain-based system aims to counteract the effects of
systemic inequalities and ensure that underrepresented groups have a
more significant impact on the outcome of elections and other democratic
processes. This paper provides a comprehensive analysis of the proposed
Privilege Index-based voting system, outlining its design, potential
benefits, and associated ethical, legal, and practical challenges. The
system incorporates zero-knowledge proofs to protect the privacy of
citizens’ personal information and assigns a vote token based on the
Privilege Index score. During the voting process, citizens burn their
vote tokens to cast their ballots, and the final results are determined
by the sum of the token values for each candidate or option. Despite the
potential benefits of the Privilege Index-based voting system, it also
raises several ethical, legal, and practical challenges that must be
carefully considered, such as accuracy of the Privilege Index, privacy
concerns, potential for manipulation, legal and ethical considerations,
and practical challenges. This paper examines these challenges and
presents strategies for mitigating them to ensure a fair and inclusive
democratic process.
Novel Scheme for GPU-Accelerated Finite-Difference Time-Domain Simulation of Electromagnetic Wave Interaction with Magnetic Plasma
Authors: He Shimin , Liu Moran , Zhou Chen , Feng Ting , Wu Yiyun , Wang Xiang
Published: July 2023

Based on graphical processing unit acceleration, a new method of
finite-difference time-domain scheme is proposed to simulate the
interaction between electromagnetic waves and magnetized plasma in
two-dimensional conditions. In this study, transversely electric and
transversely magnetic are computed in time to avoid matrix operations
involving Lorentz equations of motion. Compared to Young’s method, the
new method reduces addition and multiplication by about 63% and 66%,
respectively. The simulation results of ionospheric wave propagation
show that the new method agrees well with Young’s method and the
calculation speed is improved significantly.
A potential survival strategy during the late heavy bombardment
Authors: von Hegner
Published: July 2023

The Late Heavy Bombardment (LHB) represents a period of time in which an
increased number of impactors collided with the Earth. While there were
continuous collisions of impactors globally, these would be perceived by
populations of life as locally infrequent, as they occurred at different
times and locations across the planet. These impactions presented a severe
and unpredictable environmental pressure on life, as they could at any
moment destroy organisms and their local habitats. However, such an
environment could potentially lead to the selection of a particular
evolutionary strategy, bet hedging, which is an adaptation to
unpredictability itself. Thus, a model for analysing this has been put
forward in the form of a system of rings arising from an impact-consisting
of the inner primary and outer secondary rings, which demonstrates the
dynamic interplay between the external pressure from impact dynamics and
life's evolutionary response towards it. The model demonstrates that there
is a longer relaxed period where organisms thrive and a short violent period
where they must survive three violent events and respond to a potentially
different environment. This evolutionary strategy consistently results in a
higher number of surviving organisms compared to other evolutionary
strategies; thus, it may have played a crucial role in life's endurance
through the LHB-an insight relevant to astrobiology.

Authors: Pilipovic-Grubor Jelena , Stojanovic Sanja , Grdinic Marija , Zivojinov Mirjana , Petrovic Dejan
Published: July 2023

Introduction. Ileal leiomyosarcoma is unusual form of malignant gastrointestinal tumor. Often insidious in clinical presentation, it frequently presents a diagnostic challenge. Occasionally, a correct diagnosis is finally established due to an emergency situation. The aim of this study was to present the role of magnetic enterography in determining the precise cause of small bowel dilation. Case outline. A 59-year-old female patient presented with small bowel obstruction. Erect abdominal radiograph identified the presence of small bowel obstruction and excluded pneumoperitoneum. A non-contrast computed tomography of the abdomen and pelvis noted transitional zone in the region of terminal ileum with collapsed bowel lumen distal to the transitional point, without determined underlying cause. Magnetic resonance enterography observed obstructive intraluminal soft-tissue mass with fatty component sized up to 4 cm in the terminal ileum, with mesenteric involvement. The abdominal surgeon revealed ileal intraluminal tumor which affected the locoregional mesentery and serosa of the adjacent bowel. Histological and immunohistochemical analysis confirmed the diagnosis of ileal leiomyosarcoma with involvement of wall serosa and mesenteric fat tissue. Conclusion. Magnetic resonance enterography is a reliable diagnostic tool for detection and diagnosis of malignant small bowel tumors. Sometimes, tumors manifest clinically as bowel obstruction. Surgical treatment is necessary, while histology and immunohistochemistry are crucial to confirm the diagnosis of small bowel leiomyosarcoma.
Configuration for a grounded lossy impedance simulator employing CC-CFAs and grounded passive elements
Authors: Jain Manoj , Singh Amrita , Wairya Subodh
Published: July 2023

This article presents a configuration that can simulate both a resistor in series with a frequency-dependent negative-resistance (R-D) and a resistor in series with a capacitor (R-C), with a different selection of passive elements. The proposed circuit employs only two current-controlled-current-feedback- amplifiers (CC-CFAs) and grounded passive elements. This configuration does not require passive element matching, and the simulated equivalent element values can be tuned electronically by applying a biasing current to the CC-CFAs. To demonstrate the application of the proposed grounded series R-D impedance simulator, it is applied to a second-order notch filter and a fifth-order elliptic lowpass filter, whereas the series R-C impedance simulator is applied to a secondorder resonance circuit to find the band-pass response of the input current. Our theoretical analysis is confirmed by the results of a PSPICE simulation.

Authors: Parivar Hossein , Darabi Ahmad
Published: July 2023

In this paper, the authors present a novel analytical model for rotordynamic
analysis of a high-speed permanent magnet synchronous machine (HS-PMSM) with
a retention sleeve. The proposed analytical model has a fast response,
accurate results, and sample formulation, and is validated with the
finite-element method (FEM). The obtained results show the proper accuracy of
the proposed analytical solution approach. The significant results are: The
analytical formulation model proposed for the rotordynamic analysis of the
HS-PMSMs can accurately calculate the displacement and the stress of the
solid cylinder of the rotor at any high speeds and temperature rises.
Furthermore, the proposed analytical model is concerning the temperature
changes in the rotor and ensures requirements in any temperature rising and
high rotational speeds.

Authors: Albartouli Ahmed , Uzun Arif
Published: July 2023

This study investigated the mechanical and electrical properties of copper matrix composite materials reinforced with graphene nanosheets. The composite materials were produced using the powder metallurgy method, with several weight percentages graphene nanosheets (0, 0.5, 1 and 1.5) added to the copper matrix powders. The mixed powders were compacted unidirectionally in a steel mold at different pressures (500, 600 and 700 MPa) and sintered in an argon atmosphere at different temperatures (850, 900 and 950?C). Furthermore, the sintered samples were subjected to microstructure analysis, hardness and electrical conductivity measurements. The results showed that the microstructure exhibited porosity and agglomeration with increasing amounts of graphene nanosheets, resulting in a decrease in relative density up to 87.4%. The highest electrical conductivity was 76.59 IACS (0% GNS-500 MPa-950?C), while the lowest was 43.49 IACS (1.5% GNS-500 MPa-850?C). The addition of graphene nanosheets resulted in a relative increase in hardness of up to 1%.

Authors: Findik Tayfun
Published: July 2023

This study aims to investigate the microhardness and wear properties of AA2196 alloy, one of the new generation aluminum-lithium (Al-Li) alloys, reinforced with single and dual (hybrid) ceramic composites. The produced materials were evaluated to improve their properties. The microhardness and wear tests were conducted to assess the mechanical properties of the materials. The results indicate that the dual ceramic reinforced composite materials with AA2196 matrix exhibit superior performance compared to the single compositions. The 12% reinforced hybrid composite alloy (Alloy13) demonstrated the highest microhardness result, while the 2% and 4% reinforced hybrid composite materials exhibited the highest wear resistance. These findings suggest that the microhardness and wear properties of AA2196 alloy can be enhanced through the use of ceramic composites.

Authors: Sukirman Sukirman , Pramudita Dias Aziz , Nugroho Abdylla Adhiyasa , Aminudin Muhammad Rizky
Published: July 2023

Virtual reality (VR) is a technology that can create a simulation of real objects in a virtual environment more interactively. In terms of budget, VR devices can be categorized into low budget and high end. However, both of them can still carry out the same interactive simulations, such as educational games. This research aims to develop an educational game based in low-budget VR environment for learning computational thinking (CT), one of the 21st century skills that students need to learn. The method used is Design and Development Research (DDR) that consists of five stages: analysis, design, development, testing, and evaluation. Participants involved in this study are 30 students of vocational school (SMK) majoring Computer and Network Engineering. Evaluation conducted through Technology Acceptance Model (TAM) framework that consists of perceived usefulness (PU), perceived ease of use (PEU), attitude toward using (ATU), and intention to use (ITU). Based on the data obtained and the analysis performed, the Cronbach’s alpha score of PU and PEU were 0.714 and 0.614, respectively. Meanwhile, the Cronbach’s alpha score of ATU and ITU were 0.754 and 0.882, respectively. PU and PEU are positively correlated with ATU, while ATU is also positively correlated with ITU. It means that the ease of use of the application and the usability aspects of the developed application have a positive effect on user attitudes. This positive behavior is also positively correlated with the intention to use it again on another occasion. Thus it can be concluded that this educational game based in low-budget VR environment can be used for learning CT. It can be seen from the analysis and some positive comments from students, like participants wish they can use this learning approach in the other subject.
Decision Tree Method for Automation of Plant Sprinklers and Monitoring Based On Soil Moisture
Authors: Muchlasin Muhammad , Muhammad Hasbi  , Sri Siswanti
Published: July 2023

Watering the plants is an important part of plant care, but due to our busy schedules, we frequently forget to do it. It can be caused by a number of variables, including the weather, in addition to human irresponsibility. The goal of this research is to develop a device that can automatically water plants and monitor plants based on soil moisture. Automatic sprinklers that use NodeMCU ESP8266 and Telegram bots employ the decision tree approach. The C 4.5 algorithm is used by the Decision Tree approach to choose the microcontroller's course of action. The value of various case studies utilized in this study is determined using algorithm C 4.5. The Arduino IDE, Fritzing, and Visual Studio Code were the tools used to design and produce this tool. Additionally, it configures Telegram bots using the Telegram universal bot library. The website setting for plant monitoring employs the native PHP language, but the configuration of the telegram bot uses the general telegraph bot library. The end result is an automatic plant sprinkler that operates based on the soil moisture value and activates the water pump when the soil moisture level drops below a threshold of 50%. When the soil moisture reading exceeds 75%, the water pump will then turn off. The outcomes of this investigation also comprise websites and Telegram bots for tracking soil moisture levels.

Published: July 2023

Text Pre-Processing is the first step in Sentiment Analysis. Categorizing a sentiment in a dataset is part of the Text-Preprocessing stage to get the optimal model accuracy value. Generative Pretrained Transformer, often known as Chat GPT, is a Machine Learning model that can automatically generate realistic and meaningful text. This study aims to examine the capability of GPT Chat as an alternative in the Text-Pre-Processing stage by utilizing GPT Chat 3 from the openai.com website in the Text-Pre-Processing stage of the collected tweet data. The data used in this research is the result of crawling Twitter by inserting the keyword "Chat GPT”. This study method was carried out by measuring performance using the K-Nearest Neighbor and Naïve Bayes Algorithms to find the best performance value and compare it with the Text-Preprocessing generated by Rapidminer. It is shown that the performance accuracy produced using the K-Nearest Neighbor Algorithm is 73.57% using the Linear Sampling method. The comparison result with the Text-Preprocessing method using Rapidminer indeed shows a better accuracy of 75.33%, which means it has a narrow difference of 1.76% with the Chat GPT Text Pre-Processing method. However, both are still in the same category, which is Fair Classification. The results of this research show that Chat GPT can be an alternative in Text-Preprocessing datasets for sentiment analysis.
