How Inclusive Is The Brainstem Rule? Partiality Beyond Consensus, Charlotte Gauvry, Nurida Boddenberg

Animal Sentience

In his 2024 book, Jonathan Birch builds a precautionary framework for the borderlines of sentience, one that is meant to guide both theoretical reflection and practical action. One of the book’s great merits is its bottom-up approach, which presents itself as theoretically neutral regarding the (neuro-)physiological criteria required for sentience. Yet the singular place granted to midbrain-centric views (e.g., Merker, 2007; Panksepp, 2011; Solms, 2021) and to what Birch calls the “brainstem rule” (Chapter 11) raises questions. What justifies granting it such a central role? What are its practical and theoretical consequences?

Autofield-Poa: A Hybrid Automl–Metaheuristic Framework For Automated Feature Selection In Recommender Systems, Mohammed Dheyaaldeen Taha, Waleed Kareem Ahmed, Rana Saad Mohammed, Zied O. Ahmed

Karbala International Journal of Modern Science

The problem of automated feature selection is one of the most important aspects of modern recommender systems, as overestimating the number of feature fields used, which can increase model complexity, inference latency, and performance degradation due to redundancy and noise. Although differentiable Automated Machine Learning (AutoML) based feature selection methods, including AutoField, are effective, they remain susceptible to initialization and local optima. Conversely, population-based metaheuristic algorithms are effective at global exploration, but are often inefficient in high-dimensional discrete spaces when randomly initialized. This paper presents AutoField-POA, a hybrid AutoML-metaheuristic framework that combines a differentiable controller with the Pelican Optimization Algorithm …

An Object-Level Semantic Video Transmission Framework For Iomt Based On Lightweight Yolo And Motion Triggering, Iman Kadhum Abbood, Alaa Shawqi Jaber

Karbala International Journal of Modern Science

In Internet of Multimedia Things (IoMT) environments, video capture and frame transmission consume substantial sensor energy and impose considerable network overhead because of redundant data transmission. Traditional approaches often rely on repeated pixel-level operations and frequent execution of deep segmentation models, thereby increasing computational and transmission costs. This paper proposes an Object-Level Semantic Video Transmission Framework (OSVT) for resource-constrained IoMT environments in which high-definition visual data must be transmitted over low-bandwidth wireless multimedia sensor networks (WMSNs). The proposed OSVT incorporates a dual-stage wake-up mechanism that remains in sleep mode during static scenes, thereby reducing transmission load. The high-power YOLOv11-seg module …

Associations Of Subclinical Hypothyroidism And Thyroid Autoimmunity With Insulin Resistance Independent Of Adiposity: An Analysis Of Nhanes, Iman Taher Hussein

AUIQ Complementary Biological System

A thyroid–inflammation–insulin pathway has been proposed in which thyroid dysfunction promotes inflammation and thereby reduces insulin sensitivity, but adiposity-adjusted population evidence is limited. This cross-sectional analysis examined whether subclinical hypothyroidism (SCH) and thyroid autoimmunity are associated with insulin resistance independently of body mass index (BMI), and whether C-reactive protein (CRP), the only inflammatory biomarker available, is associated with either, using National Health and Nutrition Examination Survey (NHANES) 2007–2012 data. Non-pregnant adults aged 18–60 years with fasting glucose < 126 mg/dL and normal free thyroxine were included; SCH was defined as thyroid-stimulating hormone (TSH) 4.5–10 mIU/L, and insulin resistance was quantified by the homeostasis model assessment (HOMA-IR). Linear regression of log HOMA-IR accounted for the complex survey design (strata, clusters, weights) and was adjusted for age, sex, BMI, and survey cycle, with sensitivity and interaction analyses. Among 2,434 adults (89 with SCH), no association with HOMA-IR was detected for TSH (β = 0.009 per mIU/L; 95% CI -0.014 to 0.032), SCH (β = -0.035; 95% CI -0.186 to 0.115), or thyroid peroxidase …
