AMP Deaminase-2 Activators and Regulators Underpinning Cellular Function in Human Fructose and Nucleotide Metabolism

Abstract AMP deaminase (AMPD) plays an integral role in fructose metabolism via its regulation by ATP, GTP, and phosphate (Pi). The fructose catabolic pathway consumes ATP, producing ADP, which is further metabolized to AMP, triggering a cascade of reactions initiated by AMPD. Th...

Theory of Attractor Horizons: Form-Bound Reachability of Intelligent Organizational Forms and the Limits of Human Cognition

The development of artificial intelligence is predominantly assessed in terms of increasing cognitive performance. Yet this comparison presupposes a yardstick that captures the diversity of possible forms of intelligence only incompletely. The Theory of Attractor Horizons advance...

Climate Risk in ESG Portfolios: Evidence from Indonesian Equity Markets

We examine climate variables in a pipeline for dynamic Value-at-Risk (VaR) of the SRI-KEHATI ESG index and the IHSG (Jakarta Composite Index). Using 1,499 daily observations (20142025), we combine the Least Absolute Shrinkage and Selection Operator (LASSO) over 50 candidate predi...

Generalized Analytic Function Classes Using an Extended Two-Factor q-Differential Operator: Fekete–Szegő Problem

In this paper, we introduce an extended two-factor q-differential multiplier operator denoted by ℳq,,n,mf(z). Using this operator, we define the associated subclasses Xq,,n,m() and Yq,,n,m(,) of analytic functions. We obtain upper bounds for the initial coefficients a2, a3 and Fe...

Modified Black-Scholes Model for Valuing Employee Stock Options with Constant Exit Rate: A Case Study of a Banking Company in Indonesia

Employee Stock Options (ESO) are a form of compensation given to employees in the form of shares that can be purchased within a specified period. The ESO valuation uses the Black Scholes model, assuming employees remain employed until the vesting period is completed, excluding th...

Sobol and GJR-GARCH for Dominant Factors of European Option Prices in Blue-Chip Index Constituent Stocks

Conditional volatility-based option pricing research generally emphasizes improving volatility inputs, but has not yet fully explained the relative contribution of each parameter to variation in simulated option-pricing responses for Indonesian index stocks. This study integrates...

Diabetes Risk Prediction under Severe Class Imbalance: Comparing Firth Logistic Regression and SMOTEN-Based Logistic Regression

Diabetes mellitus is a major noncommunicable disease, and reliable early-detection prediction can support Sustainable Development Goal (SDG) Target 3.4. This study compares standard logistic regression, Firth's Penalized Logistic Regression, and SMOTEN-based logistic regression f...

A Thematic Mapping Approach to Stunting Segmentation in Indonesia by Province Using Finite Mixture Partial Least Squares Method

Stunting remains one of Indonesia’s most persistent public-health problems, and the nationalprevalence conceals subtantial variation across the country’s 38 provinces. This study modelsseven latent constructs behind stunting, antenatal care, early initiation of breastfeeding,immu...

Non-thermal effects and temperature disparities in uniform supersonic flows

Abstract Over the last 40 years, low-temperature reaction rate coefficients in astrochemical databases have largely come from CRESU ( Cinétique de Réaction en Ecoulement Supersonique Uniforme ) experiments, where the flow is described by a single temperature under an assumption o...

From orientation to action: how thinking longer at the start matters for successful complex problem-solving efficiency

Process data from complex problem-solving (CPS) tasks have allowed researchers to extensively investigate time- and action-related indicators associated with accuracy. Nevertheless, little research has examined the association between these indicators and response time in success...

Employing “FAST Water” to Accelerate Self-Assembly

Abstract Molecular dynamics (MD) simulations are a powerful tool for elucidating the molecular mechanisms of supramolecular self-assembly, but the long time scales of aggregation often make all-atom simulations computationally challenging. Here, we evaluate the recently developed...

Cycle holonomy captures higher-order compatibility constraints in remote synchronization

Higher-order interactions have typically been modeled using hypergraphs or simplicial complexes, where interactions explicitly involve more than two nodes. Here we demonstrate that effective higher-order dynamical constraints emerge naturally on ordinary graphs, provided the inte...

Abstract Let normal upper P normal upper G left parenthesis k minus 1 comma q right parenthesis P G ( k − 1 , q ) $\mathrm{PG}(k-1,q)$ be the left parenthesis k minus 1 right parenthesis ( k − 1 ) $(k-1)$ -dimensional projective space over the finite field double struck upper F S...

ActiNet: an open-source tool for activity intensity classification of wrist-worn accelerometry using self-supervised deep learning

Abstract The use of accurate and reliable open-source human activity recognition (HAR) models on passively collected wrist-accelerometer data is essential in large-scale epidemiological studies that investigate the association between physical activity and health outcomes. While...
