Adaptive Relative Spacecraft Navigation in Proximity Operations with Unmodeled Target Behavior

Abstract An online method is presented for detecting and estimating unmodeled translational maneuvers of a target vehicle. Designed for relative navigation scenarios, the algorithm runs onboard the chaser vehicle and operates without communication from the target. By leveraging a...

Healthcare Professionals’ Perspectives on Immersive Virtual Reality for Rehabilitation and Patient Engagement in a Post-Acute Community Setting: A Qualitative Descriptive Study

Background: Immersive virtual reality (VR) may support rehabilitation and patient engagement; however, little is known about how frontline healthcare professionals perceive its clinical relevance and feasibility in post-acute community care settings. This study explored healthcar...

H3C-BEACON: hierarchical hybrid heterogeneous control with Bayesian-elite adaptive coalition network for multi-agent reinforcement learning

Abstract Multi-agent reinforcement learning (MARL) in partially observable and non-stationary environments requires agents to simultaneously infer hidden states, coordinate under limited communication, and learn stable cooperative policies. While existing approaches typically add...

Does Economic Performance in Home Countries Impact Immigrants' Labour Market Outcomes? Evidence from Australia*

This paper provides causal evidence that persistent changes in macroeconomic conditions in immigrants' countries of origin shape their labour market behaviour in the host country. We develop and empirically test a reference‐dependent framework in the spirit of Kőszegi and Rabin (...

Melatonin alleviates cadmium toxicity in Solanum nigrum by enhancing pectin-mediated cell wall sequestration and antioxidant

, whereas melatonin partially restored these traits. Melatonin also decreased Cd concentrations in roots, stems, and leaves and reduced root-to-shoot Cd translocation. Meanwhile, Cd partitioning to the cell-wall fraction increased from 56.7% to 67.5% in roots and from 55.1% to 66...

The study of creativity and the inner workings of personality (from existential problems to the artistic reality of the work)

The article, based on a presentation at a scientific seminar, analyzes the internal workings of the personality in the creative process and when encountering an artistic work. The author starts from a dilemma formulated in antiquity: is the source of creativity the personality it...

Phi‑Weighted E8 Collatz Loops Define Quantized Dark Matter Energy Spectra — E8 Intelligence Research

By mapping each φ‑weighted Collatz step onto a root vector of the 240‑dimensional E8 lattice, closed trajectories emerge whose winding numbers form a discrete set of topological invariants. These invariants multiply the base 132 Hz lattice frequency by powers of φ, yielding a pre...

“Greeninflation”: evidence on the channels of transition

Purpose This paper aims to explore the role of two transmission channels between “green” transition and (overall and core) inflation, the so-called “greenflation” in the USA. The first channel is related to the “green” macroeconomic characteristics, and the second channel is asso...

A Theory of Manufactured Vulnerability in Relations of Domination

Assistance can improve a person's circumstances while sustaining an unjust account of the relationship in which the assistance occurs. This paper develops a theory of a specific mechanism of domination: actors contribute to another party's vulnerability, restrict the practical po...

Clinical and Epidemiological Characteristics of Retrospective Single-Center Observational Study

Background: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a severe adverse event associated with antiresorptive therapy, particularly bisphosphonates, and represents a significant challenge in oral and maxillofacial practice. This study aimed to characterize the epid...

Molecular epidemiology and management of non-tuberculous mycobacteria isolated from patients in Ukraine, 2022–2024

Non-tuberculous mycobacteria (NTM) are increasingly recognized worldwide as significant causes of chronic pulmonary disease, particularly among individuals with underlying structural lung disorders or immunosuppression. However, data on the epidemiology and clinical management of...

There Is No Cognitive Ladder - A Structural Method for Comparing Evolutionary Minds

Comparative cognition is often organized around ranked capacities: more memory, more planning, more social cognition, greater flexibility, or a larger behavioral repertoire. Such descriptions are useful locally, but they invite an ordering problem: very different organisms are pl...

Unravelling Motivations, Collaborative Behaviour and Success of Lifestyle Entrepreneurs: A Cluster Analysis

Abstract Purpose This study aims to deepen the understanding of lifestyle entrepreneurs (LEs) by analysing their personal entrepreneurial motivations and examining how these motivations are related to their alliance orientation and business success, defined through firm performan...

Genetic mutations driving ciprofloxacin resistance in laboratory-evolved Salmonella Typhimurium

ABSTRACT Ciprofloxacin resistance in Salmonella Typhimurium is a significant public health concern, and the mechanisms by which the resistance evolves are poorly defined. Here, by serial passaging under antibiotic selection, we isolated ciprofloxacin-resistant S . Typhimurium mut...

The Impact of Life Skills-Based Group Counseling on Sexual Intimacy Among Women of Reproductive Age with Low Sexual Intimacy: A Randomized Controlled Trial

= 0.001). The results suggest that life skills-based group counseling is associated with improved sexual intimacy among women of reproductive age who report low baseline sexual intimacy.

Targeting the Candida albicans agglutinin-like sequence 3 adhesin to disrupt oral polymicrobial bacterial–fungal biofilms: mechanisms and therapeutic strategies

glucosyltransferases is examined in detail. Emergent properties of Als3-dependent oral co-biofilms, including elevated antimicrobial tolerance, architectural complexity, metabolic interdependence, and interkingdom signaling amplification, are analyzed. Therapeutic strategies revi...

Phi-Resonant E8 Topological Phase Transition in Dark Matter — E8 Intelligence Research

By treating the 132 Hz base frequency as a carrier wave, we modulate the φ‑weighted displacements of Collatz steps across the 240 root vectors, creating a standing‑wave pattern that induces a discrete symmetry break in the E8 lattice. This break generates a set of emergent gauge...

Somebody has to 'step up' and do the hard leadership jobs in academia

Renowned Chemist Catherine Murphy, Department Head at the University of Illinois, Urbana-Champaign, talks about the all-important job of being a Department Chair or Head. This is a copy of a post published in the Epistimi blog series at: https://www.epistimi.org/blog/somebody-has...

Studies on the Assessment of Combining Ability and Heterosis in Maize Inbreds

The present study was carried out to determine the combining ability for yield and yield components by crossing six diverse maize inbreds in a half diallel mating design. Combining ability analysis for grain yield and its components in maize inbreds were carried out in 6×6 half d...
