Bifurcation Dynamics Of A Harvested Predator-Prey Model, Hala H. Emam, Mohamed F. Abouelenein, Mona Anis, M. Y. Hamada, F. A. Atia, H. El-Metwally

Mathematical Modelling and Numerical Simulation with Applications

In ecosystems, the harvesting effect is essential to preserving the relationships between prey and predator. This work examines a model of predator-prey in discrete time with harvesting. The Jacobian matrix's eigenvalues are calculated for the associated fixed points. We examine the dynamical and qualitative analysis of this model, look into the criteria for stability and bifurcation, and analyze analytical results that show the rich dynamics and complexity of this model. We give sufficient circumstances for the Period-doubling at the interior equilibrium point by employing the harvesting effect. The discrete system's chaos control is carried out, and the outcomes are supported …

Dynamic Forecasting Of Sovereign Wealth Fund Effects On State-Owned Firm Stocks Using Hybrid Arima–Garch Models, Ananta Hagabean Nasution, Teguh Yudo Wicaksono, Donny Oktavian Syah, Randhy Nugroho

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

This study examines the forecasting dynamics of Indonesia's Sovereign Wealth Fund, DANANTARA, on the BUMN-20 Index using a hybrid ARIMA-GARCH model. The establishment of DANANTARA in February 2025 generated mixed reactions among capital market participants, with the Indonesian Stock Exchange suspended trading after share prices declined by more than five percent. Using daily time-series data from June 2018 to August 2026, this study employs a hybrid ARIMA(1,1,3)-GARCH(1,1) framework processed through E-Views 12. The results indicate that the BUMN-20 Index is predominantly driven by broader market movements, as evidenced by the highly significant IHSG return coefficient (β =1.237, p < 0.001). In the mean equation, the DANANTARA announcement and launch events do not produce statistically significant shifts in average returns. However, in the variance equation, the announcement significantly elevated conditional volatility (γ = 0.025, p = 0.009), suggesting heightened market uncertainty. The volatility persistence measure (α + β = 0.952) indicates that shocks to the BUMN-20 Index decay slowly, with a half-life of approximately 14 trading days. The forecasting results suggest a gradually declining trajectory for the index, though this does not imply a causal relationship with DANANTARA. These findings contribute to the literature by demonstrating that the primary channel through which a nascent SWF affects domestic equity markets is volatility rather than returns. The policy implications highlight the importance of for transparent governance and consistent communication in mitigating market uncertainty surrounding DANANTARA's operations.

Participants included seven small business leaders located in the Southern United States who had used effective strategies to reduce employee absenteeism to avoid decreased revenue. Data were collected from semistructured interviews and publicly available documentation. Three themes emerged from thematic …

A Neutrosophic Memory-Integrity Calculus For Contradiction-Preserving Persistent Ai Agents, Rana Muhammad Zulqarnain, Saalam Ali

Neutrosophic Systems with Applications

Persistent AI agents increasingly convert interaction histories into long-lived memory, making memory transformation not retrieval alone—a central reliability problem. NMIC (Neutrosophic Memory-Integrity Calculus) formalizes the integrity of write, merge, consolidation, revision, and retrieval operations over persistent memory. Each proposition is represented through an evidence ledger carrying independent truth, indeterminacy, and falsity degrees together with reliability, provenance, temporal validity, contextual applicability, and inter-evidence dependence. A dependence-normalized hazard aggregation preserves simultaneous support and opposition while making the resulting state invariant to exact evidence duplication. Pure consolidation is governed by five integrity conditions: no support invention, no opposition invention, no manufactured certainty, contradiction …

A Data-Driven Neutrosophic Multi-Criteria Intelligent System For Functional Disability Severity Assessment, Ehab Abdel Aziz Al-Beblawi, Mirna Samy, Abduallah Gamal

Neutrosophic Systems with Applications

Functional disability assessment is a multidimensional problem because individuals may experience different levels of difficulty across daily activities such as walking, standing, dressing, eating, grasping objects, and social participation. This paper proposes NIFDA, a data-driven neutrosophic multi-criteria intelligent system for functional disability severity assessment. The proposed framework represents each functional response through three components: confirmed limitation, indeterminacy, and preserved functional ability. This allows the model to handle valid responses, uncertain information, and missing or non-informative data without forcing them into a single crisp score. To reduce dependence on subjective expert weighting, NIFDA derives criterion weights objectively using a hybrid CRITIC–MEREC …

Gagasan Kode Etik Untuk Mantan Hakim Konstitusi: Perbandingan Dengan Federal Constitutional Court Jerman, Ryan Muthiara Wasti, Fitra Arsil, Aidul Fitriciada Azhari, Fatmawati Fatmawati

Jurnal Hukum & Pembangunan

One aspect of evaluating the Constitutional Court, which has been in existence since 2003, is the issue of ethical compliance. Although a code of ethics for constitutional judges currently exists, it applies only to sitting constitutional judges. In reality, however, many former constitutional judges frequently act as parties in cases heard by the Constitutional Court. The author found that there are still former Constitutional Court judges who have served as parties—either as principals or as legal representatives. Although there is no explicit prohibition, the involvement of former constitutional judges in case proceedings raises the potential for conflicts of interest and …

Neutrosophic Indeterminacy-Transport Kolmogorov-Arnold Networks For Structured Uncertainty, Hafiz Muhammd Bilal, Kiran Naz, Anjum Ijaz

Neutrosophic Systems with Applications

Kolmogorov-Arnold Networks (KANs) replace fixed node activations with learnable univariate edge functions, but standard KAN inference treats two equal-valued features identically even when one is accompanied by an explicit quality warning. NIT-KAN introduces a neutrosophic indeterminacy-transport mechanism for this setting. Each node carries an indeterminacy state in [0, 1]; a monotone gate g(I)=⁽1-I)^α attenuates uncertain evidence on the predictive path, while a sensitivity-weighted transport rule carries indeterminacy through the underlying KAN computation. A terminal audit maps signed evidence to truth-support, falsity-support, and conflict-augmented indeterminacy without interpreting these quantities as class probabilities. We …

Neutrokoopman: Channel-Preserving Koopman Spectral Analysis Of Nonlinear Dynamics With Truth, Indeterminacy, And Falsity Evidence, Ahmed Samy, Mohamed M. Abdelhafeez, K Venkatachalam, Mohamed Abouhawwash

Neutrosophic Systems with Applications

Modern dynamical systems increasingly operate with evidence that is not merely noisy but incomplete, contradictory, or only partially trustworthy. Conventional Koopman methods represent nonlinear dynamics through linear evolution of observables, while robust and adaptive variants address parameter and model uncertainty. They do not, however, preserve the semantic distinction between support, indeterminacy, and counter-support when those conditions are compressed into a single uncertainty variable. This paper develops NeutroKoopman, a channel-preserving Koopman framework in which the physical state is augmented by a single-valued neutrosophic evidence state ν_t = ( T_t,I_t,F_t ). Deterministic and Markovian formulations are …

Jurnal Wacana Politik

This study examines the political communication models behind the success of "newcomer" candidates from Partai Gerakan Indonesia Raya (Gerindra) and Partai Demokrasi Indonesia-Perjuangan (PDI-P) in the 2024 legislative election in Tasikmalaya Regency. The research addresses a gap in existing literature which tends to analyze political marketing, digital campaigns, candidate image, or incumbent efforts in isolation by highlighting how newcomers integrate various assets such as credibility, emotional connection, and rational approaches. It also offers findings that diverge from previous studies focused on campaign team strength, mass-oriented strategies, and economic capital (money politics); instead, it emphasizes the power of personal communication through …

Determinants Of Antiretroviral Therapy Status Among Men Who Have Sex With Men (Msm) Living With Hiv In Greater Jakarta, Leonita Agustine, Mondastri Korib Sudaryo, Helwiah Umniyati

Jurnal Epidemiologi Kesehatan Indonesia

Men who have sex with men (MSM) are a key population contributing to the largest proportion of new HIV infections among the adult population in Indonesia, accounting for 44% of new infections in 2024. However, antiretroviral therapy (ART), as a key intervention in HIV control, remains suboptimal among this group, with previous studies showing that only around 57% of MSM living with HIV in Indonesia were receiving ART. In urban settings such as Greater Jakarta, these gaps may be more pronounced due to complex social and structural barriers to care. This study used a cross-sectional design based on data from …

Rekonstruksi Pengawasan Peradilan Substantif Atas Perjanjian Penundaan Penuntutan Korporasi Dalam Perspektif Civic Trust Dan Reintegrative Shaming, Merlin Swantamalo Magna, Ariesta Wibisono Anditya

Jurnal Hukum & Pembangunan

Law Number 20 of 2025 on the Criminal Procedure Code introduces the Deferred Prosecution Agreement (DPA) as a special mechanism for corporate offenders. Article 328(8) grants judges substantive authority to assess proportionality, the impact on the national economy, and the suspect's ability to meet the agreed conditions—yet provides no clear parameters. This absence risks legal uncertainty, judicial formalism, and abuse of power, while colliding with the presumption of innocence within Indonesia's civil-law tradition, in which judges have traditionally played a passive role. This study aims to construct a dogmatic framework for judges' substantive judicial-supervision authority in the DPA mechanism. Employing …

Building Health Resilience Against The Threat Of “Jakarta Sinking”: A Scoping Review, Risky Kusuma Hartono, Dewi Shinta
