This article explores Daniel Kahneman’s concept of system thinking from his book Thinking Fast and Slow (2013) in the context of contemporary spiritual and theological reflection. The question studied here is: What does the intentional use of emotions, dreams and intuition described by Daniel Kahneman as System 1 thinking look like in contemporary spiritual and theological reflection? According to Kanheman, System 1 thinking includes emotions, dreams and intuition. The method for answering the research question is hermeneutical. This means gathering texts that fit Kahneman’s description of System 1 thinking and integrating these concepts into some form of spiritual and theological reflection. Hermeneutical research is text-based. Fifty-three (53) texts were found in a search of various databases. These texts are analyzed noting the impact of System 1 thinking on spiritual and theological reflection. Findings include the following: First, there is a rise in the number of texts using System 1 thinking in spiritual and theological reflection. Second, disciplines outside of theology are practicing spiritual reflection as part of their spiritual care. Third, these non-theological disciplines are also using System 1 thinking in their spiritual reflections. Fourth, there is an awareness and utilization of diverse cultures and faith experiences in spiritual reflection. Fifth, these texts indicate the growth of the demographic of people who are spiritual but not religious and a connection to dreams, emotions and intuition in spiritual and theological reflection. Sixth, there is also a developing overlap between spiritual and theological reflection. Cautions and gaps in the textual analysis are noted as well as future applications. Full article

The ambition of policymakers to ‘raise aspirations’ among young people from disadvantaged backgrounds as a means for improving social mobility in Britain has been a mainstay of political rhetoric for the last three decades. Reports such as Higher Education in the Learning Society in 1997, Unleashing Aspiration in 2009, and Success as a Knowledge Economy in 2016 are all underpinned by an ideology of neoliberal meritocracy that has transcended political parties and governments since the Thatcher administration. Even those who lean more to the left of the Labour Party within contemporary Britain have perpetuated this narrative by reframing it as ‘working-class ambition’. This paper advances an alternative view which reconceptualises the way in which young people from non-privileged backgrounds experience and perceive the world, and their place within it. Drawing upon our work on Connected Belonging in 2025 and our research on the From the Centre to the Periphery project in 2025, we suggest that ‘hopeful optimism’ offers a more realistic lens through which to understand what is needed to address the ‘personal troubles and public issues’ that young people face. Unlike aspiration, which has an inherently individualistic and future-orientated framing, with value systems directed by dominant hegemonic notions of ‘success’ that are commonly positioned in economic terms, we recognise optimism as being a holistic and relational process that resides in the present as well as looks to the future. Optimism, grounded within principles of hope, allows young people the freedom to be and to dream; by celebrating who they are and their interconnectedness, it protects them from fears of failure; by reimaging what success might mean, it liberates them as creators.

Limited scholarly attention has been given to the fact that Islam was the first monotheistic religion whose followers encountered Australian Aboriginal peoples prior to and during British colonial settlement. Aboriginal peoples consist of numerous tribes, each with spiritual beliefs rooted in the Dreaming. The Yolŋu people of Arnhem Land exemplify the rich cultural heritage among these diverse groups. For centuries, Macassan Muslims from Makassar, Sulawesi, now known as Makassarese Muslims, were among the earliest traders to interact with the Yolŋu and to introduce Islam to the region. Contemporary Aboriginal scholars have described these encounters as a “golden age of civilisation.” This article provides a comprehensive analysis of these interactions, focusing on the introduction of Islam and its conversion among Aboriginal communities, particularly the Yolŋu. It examines the syncretism, Sufi influence and the phenomenon of “incomplete” Islamic conversion, in which northern Aboriginal peoples adopted only certain Islamic practices. A minority fully embraced Islam, especially those who intermarried. The analysis begins with Islam’s presence in Makassar, which was a crucial precursor to its introduction in Australia. By integrating interdisciplinary sources and empirical data, this study addresses a significant gap in scholarship regarding the often-overlooked contributions of Islamic civilisation at its periphery in Australia.

Despite significant progress in general-purpose diffusion-based models capable of producing high-quality media, this approach is still too difficult to implement on consumer/gamer hardware. We present here a memory-optimized DreamBooth framework designed for consumer-grade GPUs with 16 GB of VRAM, that allows for end-to-end image personalization and addresses some of the limitations of existing solutions. Our system reduces peak GPU memory from 22 GB (baseline DreamBooth) to 14.2 GB through novel hierarchical memory management, including attention slicing, Variational Autoencoder (VAE) tiling, gradient accumulation, and gradient checkpointing integrated within the Hugging Face Accelerate ecosystem. The framework further incorporates state-of-the-art techniques for preserving facial features and a comprehensive automated quality management system. The result is a complete end-to-end pipeline achieving a peak memory of 14.2 GB, with quantitative performance (LPIPS: 0.139, SSIM: 0.879, identity: 0.852, and FID: 23.1) competitive with methods requiring significantly more hardware resources.

Structural symmetry appears as a natural feature in both optimal solution landscapes and hospital scheduling behaviors, representing an inherent balance that can be deliberately leveraged to improve how quickly algorithms converge and how reliably systems perform in intricate healthcare optimization contexts. Managing hospital resources is a multifaceted challenge that requires simultaneously addressing several competing goals, such as reducing costs, improving patient experiences, making the most of available resources, distributing staff workload fairly, and strengthening readiness for emergencies. Traditional optimization approaches frequently struggle to cope with the complexity and ever-changing nature of modern healthcare environments. To address this gap, this study introduces a novel Multi-Objective Dream Optimization Algorithm (MO-DOA) tailored for smart healthcare resource management, which adapts a biologically inspired optimization framework to meet the specific demands of healthcare settings. The MO-DOA is built around three core mechanisms: a foundational memory component that retains high-quality solutions, a forgetting-supplementation component that maintains a productive balance between exploration and exploitation, and a dream-sharing component that promotes diversity among candidate solutions. Rigorous testing across realistic hospital environments confirms MO-DOA’s outstanding effectiveness, with results showing a 21.86% gain in resource utilization, a 30.95% decrease in patient waiting times, a 19.06% boost in patient satisfaction, and a 29.56% improvement in how evenly staff workloads are distributed. The algorithm’s emergency response capabilities are especially noteworthy, achieving bed assignments within 4.23 min and an equipment deployment success rate of 94.56%. Computationally, the algorithm proves highly efficient, with an average response time of 18.87 s and strong scalability across different operational scales. Collectively, these findings position MO-DOA as a powerful and practical tool for optimizing hospital operations in real time. Full article

Background/Objectives: Lucid dreaming—dreaming with the awareness that one is dreaming—has been explored from many perspectives, including those of cognitive neuroscience and various ancient cultural traditions. Lucid dreaming appears within the Tibetan-Buddhist literature together with dream yoga, a set of contemplative practices aimed at cultivating lucidity during dreams along with other qualities such as visual imagination, somatic awareness, and cognitive flexibility. These practices include deity visualization, which is the practice of bringing to mind a detailed image of a being whose qualities the practitioner wishes to cultivate. We examined whether it is possible to induce a lucid dream of Chenrezig, the ultimate embodiment of compassion in a Tibetan-Buddhist context. Methods: Five participants slept in the sleep laboratory for 7 overnight sessions with polysomnographic recording and auditory reminders to visualize Chenrezig during REM sleep. Results: Lucid dreams were reported by two participants. A frequent lucid dreamer with no prior Tibetan-Buddhist training experienced a lucid dream that included a visualization of Chenrezig following auditory cueing during REM sleep. A monastic participant with no prior history of lucid dreaming reported their first-ever lucid dream on the night following their laboratory session. Conclusions: This exploratory study illustrates, via collaborative research including monastic scholars trained in neuroscience, that dream content can be intentionally shaped using an approach that integrates contemplative visualization practices with modern techniques of dream engineering.

The Free Energy Principle (FEP) and Active Inference provide a unifying variational framework for modelling perception, action, learning, and self-organisation across biological systems. While highly successful at explaining how systems maintain organisation under uncertainty, these frameworks remain explicitly neutral with respect to a foundational question: why there is experience at all. This paper argues that this limitation reflects not an empirical gap but a misplaced starting point. The Awareness-First Theory (AFT) inverts the usual explanatory order by beginning from the givenness of awareness itself and asking what must be the case for any world to appear coherently. This requirement is formalised as a Coherence Principle, expressed as a variational stationarity condition, $\delta \mathcal{A}=0$, which specifies the invariance of coherent awareness across changing appearances. I argue that familiar variational principles-most notably free-energy minimisation ($\delta F=0$) and stationary-action physics ($\delta S=0$)-can be understood as restricted projections of this parent constraint under specific abstractions. Active Inference therefore does not generate awareness but describes how locally bounded systems maintain coherence within awareness under uncertainty. Making this projection structure explicit dissolves the explanatory gap between physical process and phenomenal presence, revealing the gap itself as a category error. Although the Coherence Principle itself is transcendental rather than empirical, the AFT generates testable consequences at the level of its projections, including predicted dissociations between inferential optimisation and phenomenological coherence in dreaming, altered states, meditation, and psychopathology.

The Set Covering Problem is a fundamental NP-hard problem in combinatorial optimization and plays a central role in a wide range of industrial decision-making processes, including logistics planning, scheduling, facility location, network design, and resource allocation. In many real-world contexts, problems of this type are large in scale and highly constrained, which makes exact solution methods computationally impractical and encourages the use of metaheuristic approaches capable of producing high-quality solutions within limited time budgets. In this work, we propose a discrete adaptation of the Dream Optimization Algorithm, focusing on the challenges that emerge when algorithms originally designed for continuous search spaces are applied to binary and strongly constrained models. The continuous search process is mapped onto the binary decision space through a fixed discretization scheme. As a consequence of this transformation, some constraints may not be met, underscoring the importance of effective feasibility restoration mechanisms. Because the discretization stage may produce infeasible solutions and frequently induces plateaus that hinder further improvement, an explicit repair phase becomes necessary to restore feasibility and promote effective search progression. To strengthen this process, the study introduces an adaptive control mechanism based on bandit driven operator selection, which dynamically chooses among different repair procedures during the search. Experimental results on benchmark instances show that the proposed approach consistently achieves high quality solutions with low relative deviation from known optima and stable behavior across independent runs.

Background: Swept-source optical coherence tomography angiography (SS-OCTA) enables rapid assessment of retinal microvasculature. However, cross-platform comparability remains limited by device-specific acquisition and image quality characteristics. This study prospectively compared two novel SS-OCTA systems, DREAM (200 kHz) and BMizar (400 kHz). Methods: Fifty eyes from 25 healthy participants underwent 3 mm × 3 mm macular OCTA imaging with both devices in a single session. Images were analysed using OCTAVA to extract foveal avascular zone (FAZ) area, vessel area density (VAD), total vessel length (TVL), node counts, fractal dimension (FD), median vessel length (MVL) in SCP, and mean vessel diameter (MVD) in DCP. Image quality was assessed using FAZ-noise rate, contrast-to-noise ratio (CNR), and FAZ noise-floor standard deviation. Paired comparisons were performed using Wilcoxon signed-rank tests and Cliff’s delta. Results: BMizar acquisition time was shorter than DREAM for the evaluated 3 × 3 mm protocol (median 5.36 s vs. 9.93 s), reflecting differences in A-scan rate and protocol implementation; acquisition time is therefore reported descriptively. In the SCP, DREAM yielded lower VAD (41.9% vs. 48.8%) and fewer nodes (1547 vs. 1879) but exhibited markedly less background noise (noise-floor SD 4.1 vs. 57.9) and substantially higher CNR (16.7 vs. 0.82). DREAM also showed longer MVL (45 vs. 39 µm) and higher FD (1.98 vs. 1.97; δ = 0.90). In the DCP, DREAM demonstrated smaller FAZ areas (0.27 vs. 0.42 mm²), thinner MVD (14 vs. 25 µm), higher node counts (3144 vs. 2301), longer TVL (223.6 vs. 206.2 mm), and higher FD (1.98 vs. 1.97), whereas VAD was higher on BMizar (32.96% for DREAM vs. 49.93% for BMizar). FAZ-noise rates were consistently higher for BMizar in both plexuses. Conclusions: Both devices provide reliable SS-OCTA imaging, but with distinct strengths. DREAM delivers higher vascular continuity and more reliable FAZ and DCP quantification, whereas BMizar achieves faster acquisition at the cost of noise, inflating SCP density and distorting FAZ-based metrics. Awareness of these characteristics is essential to ensure the valid use of OCTA biomarkers in clinical and research applications. Full article

Cellular senescence (CSEN) is caused by a variety of factors that trigger complex molecular pathways. These include telomere shortening, oncogene activation and replicative stress, as well as DNA damage caused by genotoxic anticancer drugs and endogenous and exogenous genotoxins. Here, we review the induction of CSEN by exogenous genotoxic insults resulting from food and environmental exposures. The available data show that genotoxins/carcinogens in tobacco smoke and smokeless tobacco, in the environment, in food, beverages and life-style products induce CNS. The exposures include N-nitroso compounds, polycyclic aromatic hydrocarbons, heterocyclic aromatic amines, acrylamide, heavy metals, fine dust, mycotoxins, phytotoxins, and phycotoxins. Also, heme in red meat contributes to CSEN as it catalyzes the formation of genotoxic species in the colon. Induction of CSEN by external genotoxins/carcinogens is bound on the DNA damage response pathway (DDR), which relies on activation of the ATM/ATR-CHK2/CHK1-p53-p21 axis and the p53-independent p16/p14 axis, eliciting cyclin-dependent kinase inhibition and permanent cell cycle arrest. Other factors that can be involved are DREAM, MAPK, cGAS/Sting, and NF-κB. The accumulation of non-repaired DNA damage triggering CSEN following external genotoxic exposures may contribute significantly to the amelioration of senescent cells and organ failure with age in humans. Senescent cells drive, via the senescence-associated secretory phenotype (SASP), inflammation that is involved in many diseases, including cancer. Although most of the studies were performed with in vitro cell systems, the consequences of CSEN induction by genotoxic nutritional components and environmental exposures seem to be underestimated. Since CSEN correlates with aging, it is reasonable to conclude that exogenous genotoxic pollutants contribute significantly to the aging process through CSEN induction. In light of these findings, it is deduced that reducing genotoxin exposures and using “rejuvenation” supplements (senotherapeutics) are reasonable strategies to counteract cellular senescence and the aging process.

The mean-variance rule (M-V) conforms with the expected utility paradigm only in limited and economically unacceptable scenarios. Thus, the most widely employed portfolio-selection rule seemingly loses ground. We show with the commonly employed utility functions in economics, with a preference for a positive skewness, that choosing from the M-V efficient frontier conforms with expected utility maximization even with long investment horizon and skewed distributions of returns. The economic loss induced by choosing from the M-V frontier is negligible. Thus, the M-V rule is universal, or almost universal, provided that the commonly employed utility functions in economics are employed. This is an astonishing result that even Markowitz has not dreamed of. Full article

The paper is focused on broader considerations regarding the commissioning process of the 3rd Unit of nuclear power plant VVER-440 type in Mochovce (Slovakia). The new nuclear plant built in Europe is getting much more slowly than expected, declared or scheduled. Besides the nuclear power plant in Olkiluoto (Finland) and also Flamanville (France), the 3rd Mochovce Unit has finally been in full operation since 6 November 2024. Nevertheless, the more than 30 years of construction process, which was intermittently stopped and frozen, make this success story exceptional. Lessons learned from commissioning are every time specific for different countries but commissioning of nuclear power plant without presence of general designer, respecting all safety requirements and taking full responsibility for this process is unique. Still, in general, the actual Slovak experiences and knowledge could help optimise new buildings in Europe, including dreams about small modular reactor deployment or the building of other clean and sustainable use of advanced nuclear facilities in the future.

This article examines the theoretical and practical frameworks surrounding liminal states of consciousness—specifically lucid dreaming and out-of-body experiences (OBEs)—within Indian religious and philosophical traditions. Through a comparative analysis of Vedāntic, Yogic, Buddhist, and Jain systems, the article argues that these states are not merely anomalous psychological events but deliberately cultivated “architectures of liminality” designed to investigate the nature of self, consciousness, and reality. Methodologically, this article offers a comparative analysis of models and categories of liminal consciousness across Indian traditions, critically engaging relevant neurophenomenological frameworks and incorporating a small set of representative first-person exemplars. The results reveal a spectrum of interpretations: from the mind-only projection model of Buddhist dream yoga to the subtle-material interaction model of Jain karmic ontology, and from the embodied cognition framework of modern neuroscience to the disembodied consciousness theories of classical Indian systems. The study concludes that a comprehensive understanding of liminal consciousness must integrate first-person phenomenological reports with the soteriological, ritual, and metaphysical contexts that structure their interpretation, thereby challenging reductionist approaches in contemporary consciousness studies.

Endemic racism, operationalized through exclusionary discipline practices contributes to the “spirit murdering” of youth of color in schools. While the school-to-prison pipeline frames the funneling of students into the (in)justice system, the school-to-prison nexus expands this understanding by interrogating the reality that schools are prison for many. Thus, education abolitionists call for a systemic account of “schooling” to embrace creative risk and radical possibility in the pursuit of liberation. However, existing literature has not substantively centered the voices of youth directly involved in these carceral systems, nor invited them to dream. This study asks: based on formerly incarcerated students’ experiences in school and prison, what must educational systems do to disrupt the school-to-prison pipeline? Guided by qualitative methods, we conducted semi-structured interviews with formerly incarcerated college students (four women, two men; majority Latinx/Hispanic) and conducted member checking. Our reflexive thematic analysis uncovered a troubling truth: schools frequently ignored and misinterpreted trauma, grief, and internalized pain among high school students. Participants described internal battles (i.e., mental health challenges) that often showed up externally as “behaviors” (e.g., fighting, skipping school, substance use) that resulted in exclusionary discipline. Equally important, participants re-imagined schools as homeplaces—sites of care, belonging, and agency. These narratives illuminate the need to dismantle punitive systems, center insights from those at the center of the experiences, and build just, loving, and equitable schools. Full article

In recent years, for higher education—especially in the United States—spirituality has emerged as a prominent topic on campus, both in curricular and co-curricular formats. Historically, religion has played a large role in the foundations and even missions of many universities, but in the modern era, especially for public universities, personal spirituality has become the frequent way in which topics such as meaning, values, compassion, and mindfulness are addressed. Meaning is an especially prominent theme—not only “the meaning of life” but also “meaning in life” and the individual student’s experience of “the search for meaning.” This essay explores not only previous research and theoretical proposals on the links between spirituality and meaning, but it also proposes ways in which spirituality and well-being can be relevant topics for curriculum offerings in modern universities. The essay provides one illustrative example of a way to create learning structures to support students’ exploration of practices from personal spirituality (e.g., mindfulness practices, values clarification, reflective journaling, and dream study) and how such practices can promote an enhanced sense of meaning in one’s life. The essay concludes with thoughts regarding ways in which interested faculty might collaborate to share best practices on the modern university campus to support students’ spiritual growth and their search for meaning in life.
