ZOTMPo–INAR(1) Process: Entropy and Modeling of Epidemiological Count Time Series Data

Manik Awale, Shrirang Pund, Hassan S. Bakouch, Aishwarya Ghodake et al. • Entropy (2026)

In this article, we propose a first-order integer-valued autoregressive (INAR(1)) model based on binomial thinning, in which the innovation sequence follows a zero–one–two-modified Poisson (ZOTMPo) distribution. The proposed model accommoda...

Soft theorems for boosts and other time symmetries

Lam Hui, Austin Joyce, Ilia Komissarov, Klaas Parmentier et al. • Journal of High Energy Physics (2023)

Abstract We derive soft theorems for theories in which time symmetries — symmetries that involve the transformation of time, an example of which are Lorentz boosts — are spontaneously broken. The soft theorems involve unequal-time correlati...

D-brane and exponential potentials inspire warm inflation and swampland conjecture

Shama Sadiq, Nadeem Azhar, N. Myrzakulov, S. Toktarbay et al. • Nuclear Physics B (2025)

This research explores the rapid expansion period of the early universe by applying the Chaplygin gas model, an alternative cosmological framework, to analyze the dynamics of inflationary processes. This study assesses the compatibility of ...

Economic Activity Forecasting Based on the Sentiment Analysis of News

Mantas Lukauskas, Vaida Pilinkienė, Jurgita Bruneckienė, Alina Stundžienė et al. • Mathematics (2022)

The outbreak of war and the earlier and ongoing COVID-19 pandemic determined the need for real-time monitoring of economic activity. The economic activity of a country can be defined in different ways. Most often, the country’s economic act...

From Causes to Forecasts: Granger Causality and Machine Learning Predictions of Housing Sales in Türkiye

Musa Gün, Ahmet Akusta, Haydar Karadağ • İstanbul İktisat Dergisi (2025)

This study aims to examine the impact of macro-financial indicators on the housing sales volume in Türkiye and evaluate the forecasting performance of traditional time-series models versus modern machine-learning algorithms. Using monthly d...
