Background:

Alport syndrome (AS) is an inherited disorder characterized by progressive renal disease, hearing deficits, and ocular abnormalities. This study investigates phenotypic variability among individuals with identical autosomal genetic mutations in COL4A3 and explores the potential influence of modifier genes. The study focuses on three families carrying the same COL4A3 mutation (c.2083G>A, p.Gly695Arg) but exhibiting differences in phenotype. The objective is to elucidate interfamilial and intrafamilial variations and identify potential genetic modifiers contributing to these differences.

Methods:

Three families from a cohort at the University of Utah were studied. Clinical data, blood, urine, and tissue samples were collected with informed consent. Whole-exome sequencing (WES) was performed to identify genetic variants, using the SureSelect Human All Exon Target Enrichment System. Variant calling and annotation were conducted with GATK, VEP, and PEDDY. Disease-gene prioritization was achieved using the Variant Annotation, Analysis, and Search Tool (VAAST), pVAAST, and the Phenotype Driven Variant Ontological Re-ranking Tool (PHEVOR). Modifier genes were identified through co-segregation analysis and functional annotation using public databases.

Results:

The study highlighted significant phenotypic variability within and between families with the same COL4A3 mutation. Individuals with single mutations often presented mild phenotypes, such as isolated hematuria, while compound heterozygotes and digenic cases exhibited severe manifestations, including proteinuria, hearing loss, and chronic kidney disease (CKD). Modifier genes such as GRIP1, CCND1, and CYP3A7 were identified and linked to phenotypic variability, suggesting their potential role in disease progression.

Conclusions:

The findings underscore the role of genetic modifiers in influencing phenotypic variability in AS. Understanding these modifiers is crucial for personalized therapeutic strategies and genetic counseling. Future research should validate these candidate genes through functional studies and larger cohorts to enhance clinical care and improve prognostic predictions for patients with AS.
ORGANIZATION OF HELP FOR CHILDREN WITH DISORDERS AUTI SM SPECTRUM ABROAD
Authors: Golovanov S.A.
Published: February 2025

The article, which analyzes and summarizes information on the prevalence of autism spectrum disorders, shows the true extent of the disease, as well as the risks of developing cognitive and behavioral disorders in children. This significantly affects the quality of life of patients with autism spectrum disorders and their relatives, which is explained by the lack of comprehensive etio-pathogenetic treatment and preventive measures. Numerous studies confirm that timely identification of autistic disorders and inclusion of the child in early intervention programs can serve as the basis for effective rehabilitation and improve the prognosis of socialization. Literary data confirm that medical rehabilitation should begin at an early stage of the development of autistic disorders, in physiologically favorable years for the child (from 2 to 7 years). The conclusion is that patients with autism spectrum disorders require special treatment throughout their lives.

Objetividad, formación de investigadores y crisis del conocimiento: Factores explicativos de la actual angustia innovadora
Authors: Moreno López William
Published: February 2025

La objetividad constituye un elemento fundamental en los documentos que se publican, una exigencia para conferirles carácter académico; en esta perspectiva trasciende la formación de investigadores y del sistema de investigación en los centros de Educación Superior. No obstante, la objetividad es cuestionada desde mediados del siglo XX, particularmente por la denominada Escuela de Frankfurt, y en la actualidad en el marco de una evidente crisis del conocimiento, manifiesta en el insistente llamado a la innovación en diversos campos.
El objetivo de este trabajo es establecer la relación entre tal objetividad en la formación de investigadores y su incidencia en la crisis del conocimiento que hoy se expresa en el clamor por innovación; en su desarrollo, la metodología de investigación, cuyos resultados se consignan en este documento descriptivo, es de tipo cualitativo y procede de la revisión bibliográfica y el análisis de documentos de autores latinoamericanos como Zemelman, Quijano, Dussel así como del comité regional de Ciencias Sociales –CLACSO-.
Los resultados, dan cuenta de la crítica a la actual formación de investigadores centrada en esa referida objetividad, para pasar al análisis de la incidencia que ésta tiene en la crisis del conocimiento que permanece estancado, en un estado que lleva a concluir sobre la urgente necesidad de empoderar metodologías alternativas, en las que sea posible una integración activa del sujeto, que conduzca el proceso innovador que tanto se requiere.
Effectiveness of Silica Sulphate Catalyst Based on Rice Husk Ash in The Oleic Acid Esterification Process
Authors: Ade Rifqi Maulana  , Dwi Febriani Anisa , Lidya Elizabeth  , Eko Andrijanto
Published: February 2025

Rice husk contains a lot of silica, so it is widely used as research material. One example is as a raw material for the synthesis of silica sulfate. Silica sulfate was synthesized using the sol-gel method with an impregnation time of 6 hours and 2 hours of calcination with variations in calcination temperature of 400-800oC. The analysis carried out on the silica sulfate catalyst is the analysis of acid concentration and FTIR. The best acid concentration results were 0.86 mmol/gram at 400oC. Characterization with FTIR showed similar peaks between silica and silica sulfate. The -OH and Si-O groups appeared at the peak of the analysis results, indicating that the synthesis of silica from rice husk had been carried out successfully. Modifying silica with sulfuric acid is not obvious through FTIR because the S-OH groups of sulfate ions overlap with the silica atoms in siloxane. The resulting silica sulfate is used as a catalyst in the esterification reaction of oleic acid with methanol. The esterification process was carried out at 60oC and varied with independent variables, namely catalyst loading (5-10%-b), time (2-4 hours), and molar ratio (1:6-1:12). The experimental design was determined using the Response Surface Method (RSM) using Design Expert. From the study results, the best variation obtained was a conversion of 87.03% with a variation of catalyst loading of 7.5%-b, a time of 4 hours, and a molar ratio of 1:12.

Authors: Lidya Bevi , Rahma Wildiani Isnaeni , Zikri Ramadhan Muhammad , Hariyadi Tri
Published: February 2025

Fermentation is the key to every post-harvest processing method carried out. Fermentation in coffee also serves to determine the characteristics of the resulting coffee. To bring out the characteristics of coffee, modification of the fermentation process is used by adding lactic acid bacteria which aims to reduce the caffeine and pH levels in coffee. Low pH in coffee can protect coffee beans from another microorganism and give fruity flavour in coffee. This research aims to determine the effect of lactic acid fermentation time on processing with the full wash and honey method on the characteristics of arabica coffee beans. Fermentation is done with time variations of 8, 16, 24, 32, 40, and 48 hours. The post-harvest processing carried out is the full wash and honey method. The analysis was carried out to determine the water content (gravimetric method), caffeine content (UV- Vis spectrophotometry), pH (pH metre), and total acid level (titration method). The results showed that the longer the fermentation time, the lower the caffeine content and pH levels in coffee. Processing with the full wash method produces lower caffeine levels, while the honey method produces a lower pH and a higher total acid content. The best experiment was obtained at 40-hour fermentation using the honey method, with water content of 9.07%; caffeine 1.11%; pH 4.00; and total acid content of 27%, based on SNI 2008.

Exploring Blind and Low-Vision Youth’s Digital Access Needs in School: Towards Accessible Instructional Technologies
Authors: Shaheen Natalie L.
Published: February 2025

Blind and low-vision (BLV) youth have been excluded from technology-mediated learning in school for two decades due to the systemic inaccessibility of K-12 instructional technologies. Accessibility guidelines that address BLV youth’s needs would help schools address this systemic inequity. But such guidelines do not yet exist nor does the robust knowledgebase required to write them. Herein, I report three key findings from a mixed methods user study of BLV youth's lived experiences learning with access technologies (AT) and instructional technologies in U.S. schools. First, these youth participants are using a broader range of AT than youth in previous studies. Second, the youth in this study frequently developed their AT literacy outside of school and most did not begin developing AT literacy in earnest until they were teens. Third, the youth defined accessible instructional technologies as those that are (1) easy to learn to use and (2) easy to use to learn and they used an inquiry process to evaluate accessibility. Building on the findings, I offer six preliminary design guidelines for accessible instructional technologies. Finally, I urge other scholars to study BLV youth’s digital access needs so that standards setting bodies eventually have sufficient data to write youth accessibility guidelines.

Pomyśleć dewzrost, czyli dekapita(liza)cja kapitału
Authors: Zbrzezny Aleksander
Published: February 2025

Celem artykułu jest namysł nad strategią dewzrostu. Wskazując rozmaite trudności, autor skupia się na wskazaniu pola, którego teorie dewzrostu nie mogą pomijać, jeśli chcą pretendować do skuteczności: to dominująca ekonomia polityczna. Podążając za myślą Marksa, autor argumentuje, że adekwatnym do postulatów dewzrostu trybem funkcjonowania społeczeństwa musiałaby być właściwie „reprodukcja zawężona”. To o tyle trudny ruch, że oprócz logiki akumulacji do przezwyciężenia jest także mechanizm alienacji oraz nasze konsumpcyjne nawyki. Dopiero na tym tle można szukać przykładów radykalnej, społecznej zmiany, której skala odpowiadałaby wymogom dewzrostu. Według autora przykładem takim może być częste w epoce neolitu odchodzenie od rolnictwa (Graeber, Wengrow). Nie chodzi tu jednak o (niemożliwe) powtórzenie takiej decyzji, a o samą zdolność do jej podjęcia. Oznacza to jednak dekapita(liza)cję kapitału.
Zarządzanie kulturą w czasach dewzrostu – fabulacja spekulatywna
Authors: Wydra Jakub , Pałasz Michał
Published: February 2025

The aim of the study was to explore the possible future of culture management under conditions of degrowth, which was treated in the research as an appropriate response to what natural scientists regard as the real risk of an imminent collapse of planetary systems due to humanity’s historically extractive and exploitative global economic activities. The article fills a research gap on the potential role of culture management in a degrowth-based transformation. The experimental research methodology was based on speculative fabulation, SWOT and PESTEL analytical frameworks. The main conclusion of the study is that degrowth conditions may provide a space for culture management to flourish, while the cultural sector has significant potential to provide infrastructural and value-based support for the degrowth transformation.

This inequality is evidenced by the long-standing male dominance in the industry, where male musicians are consistently favoured over their female counterparts. Consequently, the percentage of female musicians remains substantially lower than that of male musicians. Addressing this issue, Spotify, one of the largest companies in the global music industry, has initiated support for female musicians worldwide through its campaign titled Spotify EQUAL. Through this initiative, Spotify has committed to addressing gender inequality issues in the global music industry. This research focuses on analyzing the efforts undertaken by Spotify through its gender equality campaign, Spotify EQUAL. The study employs feminist theory as a social movement framework underlying gender equality campaigns. Additionally, the authors utilize the concept of digital activism, which encompasses four strategies, to analyze the campaign efforts conducted by Spotify and its Ambassador in the Spotify EQUAL program. This research adopts a qualitative descriptive approach, explaining the analytical result of the efforts implemented in the Spotify EQUAL gender equality campaign.
Two-dimensional finite difference-time domain simulation of moving point source array
Authors: TSUCHIYA Takao , Inoue Kei
Published: February 2025

In this paper, a moving point source array is theoretically described and implemented in a two-dimensional finite difference-time domain (FDTD) method. The directivity of the moving point source array is theoretically derived by considering phase differences between each source in the two-dimensional field. Then, the moving point source array is implemented in the two-dimensional FDTD method. Numerical experiments were conducted for point source array with in-phase driving and phased array in the two-dimensional sound field. The FDTD method was confirmed to be able to calculate with less than 1% error up to Mach number 0.4. It was found that the effect of the moving velocity on the directivity increased with increasing source velocity. It was also found that the directivity varies with the direction of sound radiation due to the Doppler effect. The proposed method can be accurately applied to moving point source array.
Effect of relay tube geometry on the onset temperature in loop-tube thermoacoustic systems
Authors: SAKAMOTO Shin-ichi , Ono Satoru , Hirayama Satoshi
Published: February 2025

This study experimentally and numerically investigates a loop-tube thermoacoustic prime mover, which connects two tubes of different inner diameters. Previous research has focused on expanding the prime mover section to improve energy conversion efficiency, but this study emphasizes the effect of joint discontinuities by inserting a relay tube at the connection. Both experimental measurements and stability analysis were conducted, varying the relay tube's inner diameter and length. The results show that smaller diameters and longer relay tubes reduce the onset temperature, demonstrating good agreement between experimental and analytical results. Conversely, the relay tube's dimensions were found to have little impact on the oscillation frequency. This contributes to developing more efficient thermoacoustic systems.
An explanation of reported dependence of backward diffusion of Zn in (100) InP on misorientation directions by relating kink velocities to Zn incorporation sites during metalorganic vapor-phase epitaxy
Authors: Mochizuki Kazuhiro , Ohta Hiroshi , Mishima Tomoyoshi
Published: February 2025

Reported dependence of backward diffusion of Zn in (100) InP on misorientation directions was explained by relating kink velocities to Zn incorporation sites during metalorganic vapor-phase epitaxy. Because of the larger density of kinks per phosphorus-terminated steps (B-steps) compared to the density of kinks per indium-terminated steps (A-steps), we assumed that most of the Zn atoms surface-diffusing toward B-steps should be incorporated into In-sublattice sites, whereas those surface-diffusing toward A-steps should go into tetragonal interstitial positions surrounded by P atoms. This assumption was supported by the resultant reproduction of the reported backward diffusion profiles of Zn in InP.
Integrating the Capital Asset Pricing Model with the Analytic Hierarchy Process and the Delphi Method: a proposed method for estimating the discount rate in constrained real estate development initiatives
Authors: Battisti Fabrizio , Acampa Giovanna , Grasso Mariolina
Published: February 2025

The legislative framework on territorial and urban planning has become increasingly rich and complex in the European Union, particularly Italy. The structured – and often hindering – system of division of responsibilities between the central State, Regions, local institutions, and organisms generates different levels of administrative verification. The environmental and landscape constraints by which each Public Administration with jurisdiction over the territory exercises its powers strongly impact territorial management and negatively affect investments. Over the years, this has been one of the main reasons behind the significant dilation of the risk and the time required to obtain the necessary authorizations to start construction, producing “business risk.” Based on this premise, this work presents a methodological investigation of the relationships between environmental and landscape constraints, the regulatory framework involving the building, and its Market Value. This is finally aimed at finding suitable methods and procedures to formulate a reasonable discount rate considering the constraints and the related regulations that operate on an asset. A multi-step method integrating the Capital Asset Pricing Model, Analytic Hierarchy Process, and Delphi Method is proposed to assess the discount rate component related to urban risk.

Published: February 2025

Objectives: To evaluate the contribution of Ultra to the diagnosis of pediatric pulmonary tuberculosis (PTB). Methods: We analyzed prospective data from children and adolescents with presumed PTB whose specimens were tested with Ultra between January 2020 and December 2022. Diagnosis was based on clinical-radiological criteria, clinical response after a two-month treatment period, and microbiological analysis. Ultra was considered positive with a result of 'Detected' and 'Traces' in children under 10 years and in HIV-infected individuals. Fisher's exact test was used for group comparisons, and McNemar's test was used to compare Ultra results with the diagnostic presumption. The study was approved by the Ethics Committee (CAAE No. 02173518.2.0000.5264). Results: A total of 41 patients were included, of whom 63% (26/41) were diagnosed with PTB. Among these, 9/26 (34%) had positive results only through Ultra, with negative AFB and culture. The sensitivity and specificity of Ultra were 50% (13/26) and 100% (15/15), respectively. The PPV was 100% (13/13), and the NPV was 54% (15/28). Of these 28 (68%) patients with negative Ultra results, 13 (46%) were diagnosed with PTB, mostly by MoH-SS. Considering culture as the reference, the PPV and NPV were 67% and 100%, respectively. Conclusions: Ultra significantly contributed to the diagnosis of pediatric PTB, proving to be a promising tool for paucibacillary forms of the disease. However, it should not be used alone. Integrating laboratory tests with clinical evaluation is essential to improving diagnostic accuracy and the management of pediatric TB.

THE EFFECTIVENESS OF USING ADDITION-BASED MATHEMATICAL FORMULAS IN IMPROVING CRIMINOLOGY STUDENTS' MASTERY OF VERB TENSES AND ASPECTS
Authors: Lemuel J. Segara
Published: February 2025

The mastery of verb tenses and aspects is essential for criminology students, as precise grammar is crucial for professional communication in legal reports, case analyses, and investigative documentation. However, traditional grammar instruction often relies on rote memorization, which may not effectively support students in grasping complex grammatical rules. This study investigates the effectiveness of addition-based mathematical formulas as an instructional tool to enhance students' mastery of verb tenses and aspects. Grounded in Cognitive Load Theory (Sweller, 1994), Vygotsky’s Zone of Proximal Development (1978), and Piaget’s Cognitive Development Theory (1972), this research proposes that structured, rule-based learning can facilitate more effective grammar acquisition.
A quasi-experimental research design was employed, involving 90 criminology students from a higher education institution in the Philippines. Participants were divided into an experimental group, which received instruction using addition-based mathematical formulas, and a control group, which was taught using traditional grammar instruction. Data collection involved pre-tests and post-tests to measure students' proficiency before and after the intervention. Statistical analysis using paired-sample t-tests and independent-sample t-tests was conducted to determine the significance of the results.
Findings indicate that the experimental group (M = 38.045, SD = 7.427) significantly outperformed the control group (M = 29.974, SD = 8.054), with a t-value of 4.726 and a p-value of .000, indicating a statistically significant difference at p < 0.05. These results confirm that addition-based mathematical formulas effectively improve students' mastery of verb tenses and aspects by providing a structured, logical approach to grammar learning.
The study highlights the pedagogical potential of interdisciplinary teaching strategies, particularly the integration of mathematical reasoning into language instruction. It recommends that higher education institutions incorporate mathematical structuring into grammar instruction, particularly for students in technical disciplines such as criminology. Additionally, further research should explore the long-term retention effects of this approach and its applicability in other linguistic domains, such as syntax and morphology.

RELATIONSHIP BETWEEN ATTITUDE AND WHISTLE BLOWING INTENTIONS AMONG EMPLOYEES IN PUBLIC UNIVERSITIES IN KENYA
Authors: Dr. Meshack Kipkoech Katam
Published: February 2025

Whistle blowing is essential to organizations as it helps to expose misbehavior which if left, may degenerate to unethical actions that may bring disrepute to the organization or lead to loss of property. Even though whistle blowing in Kenyan public universities is rare, some surveys have illustrated instances of whistle blowing from both members of the public and administrators. The purpose of this study was to determine to determine the relationship between attitudes and whistle blowing intentions among employees in public universities in Kenya.
The study was anchored on the theory of planned behaviour. The study adopted a positivist research philosophy and correlational research design and utilized questionnaires as the main tool in collecting primary data. A coefficient of 0.85 was obtained using the Cronbach Alpha which showed internal consistency. Descriptive statistics were obtained using frequencies and percentages. Multivariate linear regression was used to determine the factors that were associated with whistle blowing intentions among employees in public Universities in Kenya. The target population was 30,818 employees from public university in Kenya. A sample size of 395 respondents was obtained using Yamane formulae. Proportionate sampling was used to obtain the number of respondents in each university and simple random sampling was used to select respondents to fill the questionnaires. Descriptive statistics were analyzed in form of Mean and Standard deviation while multiple linear regression model and correlation analysis were used to establish the relationships of the study constructs. The relationship between attitude and whistle blowing intentions was significant. One unit increase in attitude led to an increase in whistle blowing intentions by 0.12 (R2 = 0.21, β = 0.12, p-value = 0.024). The study findings revealed that gender, altruism, ethical values and attitude all have positive and significant relationships with whistle blowing intentions and organizational support moderates the relationship. The study recommends that universities should continuously sensitize employees on whistle blowing so as to promote the culture of whistle blowing.

The introduction of a new educational standard required changes in the ap-proach to management in educational organizations. The introduction of the Federal State Edu-cational Standard presupposes the availability of a material and technical base, the use of inno-vative computer technologies, and advanced training of teaching staff. The need for innovative changes is caused by multiple and contradictory transformations of a scientific, technological, and socio-man-made nature. They are complex, but they become part of a person's daily life. Therefore, regardless of the goals, orientation and intensity of such processes, the idea of hu-manity, humanism and the preservation of heritage for future generations of people should be at the heart of all innovative initiatives.

Sampah sering dianggap tak berguna oleh mayoritas masyarakat, namun, di kalangan masyarakat ekonomi rendah, memungut sampah untuk dijual ke tempat daur ulang menjadi cara untuk memenuhi kebutuhan sehari-hari. Sampah juga dapat dihasilkan atau didaur ulang untuk digunakan kembali di rumah tangga, seperti kaca plastik, sendok, dan berbagai bahan untuk keperluan rumah tangga. Penelitian ini dilakukan di Provinsi Gorontalo, Indonesia, utara Pulau Sulawesi, menggunakan metode penelitian kualitatif. Data dikumpulkan melalui pengujian langsung di lapangan dan referensi literatur seperti jurnal, buku, dan internet. Hasil pengujian menunjukkan bahwa laju aliran udara yang digunakan memiliki pengaruh signifikan terhadap nilai Air Fuel Ratio (AFR), yang menggambarkan perbandingan udara dan bahan bakar. Semakin kecil nilai AFR, semakin baik konsumsi bahan bakar. Analisis menunjukkan bahwa Equivalent Ratio (ER) dari setiap pengujian bervariasi antara 0,22 hingga 0,25, dengan ER terendah sebesar 0,15. Semakin kecil nilai ER, semakin tidak sempurna produksi syngas. Nyala api terbaik ditemukan pada AFR aktual 1,15 dengan ER 0,25 pada kecepatan udara 10 m/s. Selain itu, suplai udara ke dalam ruang reaktor berpengaruh pada warna nyala api, dengan peningkatan suplai menghasilkan nyala api yang lebih kemerahan. Berdasarkan analisis nyala api efektif, ditemukan durasi waktu terbaik sebesar 567 menit pada AFR 1,15 dengan laju konsumsi bahan bakar 7 kg/jam. Penelitian ini memberikan wawasan penting mengenai optimalisasi proses pembakaran sampah untuk produksi syngas dengan menggunakan reaktor tertentu pada kondisi tertentu.

On the Quantum Chromatic Numbers of Small Graphs
Authors: Lalonde Olivier
Published: February 2025

We make two contributions pertaining to the study of the quantum chromatic numbers of small graphs. Firstly, in an elegant paper, Mančinska and Roberson [Baltic Journal on Modern Computing, 4(4), 846-859, 2016] gave an example of a graph $G_{14}$ on 14 vertices with quantum chromatic number 4 and classical chromatic number 5, and conjectured that this is the smallest graph exhibiting a separation between the two parameters. We describe a computer-assisted proof of this conjecture, thereby resolving a longstanding open problem in quantum graph theory. Our second contribution pertains to the study of the rank-$r$ quantum chromatic numbers. While it can now be shown that for every $r$, $\chi_q$ and $\chi^{(r)}_q$ are distinct, few small examples of separations between these parameters are known. We give the smallest known example of such a separation in the form of a graph $G_{21}$ on 21 vertices with $\chi_q(G_{21}) = \chi^{(2)}_q(G_{21}) = 4$ and $ \xi(G_{21}) = \chi^{(1)}_q(G_{21}) = \chi(G_{21}) = 5$. The previous record was held by a graph $G_{msg}$ on 57 vertices that was first considered in the aforementioned paper of Mančinska and Roberson and which satisfies $\chi_q(G_{msg}) = 3$ and $\chi^{(1)}_q(G_{msg}) = 4$. In addition, $G_{21}$ provides the first provable separation between the parameters $\chi^{(1)}_q$ and $\chi^{(2)}_q$. We believe that our techniques for constructing $G_{21}$ and lower bounding its orthogonal rank could be of independent interest.
A Proof of the $(n,k,t)$ Conjectures
Authors: Baumann Stacie , Briggs Joseph
Published: February 2025

An $(n,k,t)$-graph is a graph on $n$ vertices in which every set of $k$ vertices contains a clique on $t$ vertices. Turán's Theorem, rephrased in terms of graph complements, states that the unique minimum $(n,k,2)$-graph is an equitable disjoint union of cliques. We prove that minimum $(n,k,t)$-graphs are always disjoint unions of cliques for any $t$ (despite nonuniqueness of extremal examples), thereby generalizing Turán's Theorem and confirming two conjectures of Hoffman et al.

Published: February 2025

Seabed mining, which focuses on extracting minerals from the ocean floor, is vital for the sustainable development of the green economy. With current initiatives targeting coastal waters exceeding 200 meters deep, these areas yield sand, tin, and diamonds crucial for meeting the growing demand in the energy transition and new technologies. Unlike onshore mining, deep-sea mining lacks stringent national regulations, presenting an opportunity for Islamic finance. This alternative aligns with long-term investment principles, risk sharing, and environmental responsibility, addressing the absence of an international legal framework. The essay explores the benefits of Islamic finance in funding deep-sea mining, ensuring project viability, sustainability, and environmental preservation. Additionally, an artificial intelligence framework is proposed to optimize funding for such projects.
