Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

Second Order Mock Theta Functions

, 2007
In his last letter to Hardy, Ramanujan defined 17 functions F(q), where |q| < 1. He called them mock theta functions, because as q radially approaches any point e2πir (r rational), there is a theta function Fr(q) with F(q) − Fr(q) = O(1).

From Dedekind’s Level 12 Identities to Combinatorial Structures of Colored Partitions

Axioms
The Dedekind η-function plays an important role in number theory, particularly in the study of modular forms, q-series, and partition identities. In this paper, we investigate several level-12 η-function identities and examine their combinatorial ...

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Decision time, slow inhibition, and theta rhythm [PDF]

, 2010
In this paper, we examine decision making in a spiking neuronal network and show that longer time constants for the inhibitory neurons can decrease the reaction times and produce theta rhythm.We analyze the mechanism and find that the spontaneous firing

Speaking to Power: How Linguistic Minority Accents Shape Voter Perceptions of Party Leaders

Nations and Nationalism, EarlyView.
ABSTRACT In multilingual countries, does the way minority group members speak the majority language hinder their chances of attaining the highest political office? Can their accent undermine their claim to represent all citizens? Is it associated with certain stereotypes?

Asymptotics for Bailey-type mock theta functions [PDF]

The Ramanujan Journal, 2021
AbstractWe compute asymptotic estimates for the Fourier coefficients of two mock theta functions, which come from Bailey pairs derived by Lovejoy and Osburn. To do so, we employ the circle method due to Wright and a modified Tauberian theorem. We encounter cancelation in our estimates for one of the mock theta functions due to the auxiliary function $$\

Learning alters theta amplitude, theta-gamma coupling and neuronal synchronization in inferotemporal cortex [PDF]

, 2011
Background: How oscillatory brain rhythms alone, or in combination, influence cortical information processing to support learning has yet to be fully established.

Inter‐Rater Reliability of AI Scores: A Call to Move from Correlational to Factor Analytical Estimation

Personnel Psychology, EarlyView.
ABSTRACT Artificial intelligence (AI), such as large language models (LLMs), is increasingly being used to score psychological and organizational constructs from text. However, the reliability and validity of these scores remains vital. Frequently, AI scores are treated as replicants of human ratings and inter‐rater reliability (IRR) is established by ...
