<p>The accuracy of the experimental data is crucial to the results obtained in Special Core Analysis (SCAL), particularly in relative-permeability experiments. The precise quantification of the produced fluids is used to calculate fluid saturations, as measurement errors propagate directly into the resulting relative permeability curves and reservoir production forecasts. Various methodologies are used to quantify production in SCAL experiments, including ultrasonic and visual detection of the fluid's menisci. While manual or semi-automated reading and identification methods are already used in industry, they are prone to human subjectivity and parallax error, which can lead to low accuracy. Therefore, this work proposes a fully automated, high-resolution, and robust methodology for tracking fluid interfaces in visual separators. <br>The proposed system integrates Deep Learning for meniscus detection with a computer vision framework that manages: (i) automated camera positioning to track interface displacement; (ii) Optical Character Recognition (OCR) and pattern recognition for high-resolution instrument reading; and (iii) optical distortion corrections. A high-precision measurement system was developed to replace the conventional human reading ruler-based method typically used in the SCAL experiment, thereby significantly reducing measurement uncertainty. Results demonstrate a more than one-order-of-magnitude increase in the precision of interface height measurements. The correlation between camera resolution and measurement sensitivity is also analyzed. </p>

<p>This study employs computational fluid dynamics to evaluate how oil in a Buff Berea core can be displaced by brine when different coreholder heads are used. The Finite Volume Method (FVM) and commercial fluid dynamics software were used. The multiphase flow was simulated in the horizontal orientation and solved for various coreholder head layouts using the volume-of-fluid (VOF) numerical algorithm, which tracks the interface between phases. Moreover, relative permeability, capillary pressure, and gravitational effects were accounted for in the solution of the governing equations, thereby enabling a solid numerical approach. The homogeneity of the front flow was quantified using concepts from the variogram, a tool mainly used in geostatistical analysis. Findings indicate that, depending on the coreholder’s head layout, a more homogeneous front flow can be achieved. The simulations show oil production varying by up to 32%, indicating that the core head layout may play a key role in assessing petrophysical properties. Based on the results, the use of head geometries that promote a uniform displacement front is recommended, as they improve sweeping efficiency. </p>
The Replication Hypothesis: Information as a Fundamental Property of Matter and Evolution as a Continuation of Physics

<p>Information is not a description applied to matter after the fact, but is given along with the spin and position of its smallest constituents from the very beginning. From this premise of information physics, the essay develops a hypothesis about the question of where biological information stores originally obtain their information, and it seeks the answer not first in life, but in matter itself. The starting point is quantum Darwinism, according to which the state of a system imprints itself redundantly upon its environment and, precisely through this redundancy, becomes independently accessible to many observers, that is, objective. Because storage and energy remain finite and every record physically costs something, every system stands under a twofold pressure: to continually accumulate copies while at the same time encoding them ever more sparingly. From this tension the essay grounds both the distinction between static and dynamic information and the thesis that selection and adaptation arise as a substrate-neutral consequence already from the physics of matter, without requiring new laws of nature. As a unifying motif, the essay introduces the <em>replication hypothesis</em>, according to which physically embodied information tends to be multiplied and is thereby driven, over generations, toward ever more efficient packaging. This single tendency is traced across successive levels, from the quantum substrate through the genome and the human brain to artificial systems that require ever less energy per computational step, and it is bounded where the energy flow is interrupted and the cheapest option is to hold a record rather than to work on it. The individual links of the chain rest on established research, whereas their integration into a single, directed movement remains designated as a hypothesis, together with the observations that would tell against it. Its appeal lies in offering a parsimonious alternative for the origin of biological information, one in which evolution is not the counterpart to physics but its continuation by other means.</p>

<p class="font-claude-response-body break-words whitespace-normal">This paper proposes a candidate mapping between a mathematically established delay-induced variance-divergence phenomenon (derived in a companion theoretical study of linear stochastic delay-differential equations) and longitudinal neurological biomarker trajectories. Rather than presenting validated clinical results, the paper specifies a falsification-oriented framework: an explicit scheme for estimating latent delay and feedback parameters from biomarker time series (e.g., p-tau217, NfL, structural MRI), a pre-specified definition of what would constitute a positive versus negative result, and a concrete validation protocol against established baselines (Cox proportional hazards, gradient-boosted trees) using public longitudinal cohorts such as ADNI, OASIS, or NACC. No patient-level data, clinical results, or diagnostic/prognostic claims are made in this paper; its contribution is a testable hypothesis and a pre-registerable study design intended to guide a future validation study.</p>

An injured dermal-endothelial cell-state signature of systemic sclerosis peripheral vasculopathy replicates across independent cohorts, is distinct from the endothelial-to-mesenchymal transition, and motivates a non-vasodilator framework

<p>Companion paper to U.S. Provisional Patent Application No. 64/124,874 (priority August 3, 2026; Ritschel Research). Discovery-stage computational analysis. The peripheral vasculopathy of systemic sclerosis (SSc), which produces Raynaud's phenomenon and digital ulcers, is treated almost entirely with vasodilators that do not resolve the underlying injured endothelium. Here an injured dermal-endothelial cell-state signature, anchored by the SSc endothelial-injury markers HSPG2 and APLNR, is derived from SSc skin single-cell RNA sequencing (GSE138669) and independently replicated in a second cohort (GSE292979), where it is elevated in SSc endothelium relative to control (rank-sum p = 3.8e-70 and p = 1.9e-35). The state is shown to be reproducibly distinct from the endothelial-to-mesenchymal transition, which was scored in parallel, was not the separator, and reversed direction between cohorts. An angiogenic-competence program was not reduced (consistent with the non-productive angiogenesis of SSc), so no claim is made to restoring angiogenesis. Hardened signature-reversal repurposing, after excluding vasodilator, kinase-inhibitor, cytotoxic, and tool-compound perturbagens, was exhausted; the paper therefore outlines a mechanism-anchored, non-vasodilator framework (endothelial-adhesion antagonism, angiopoietin-2/Tie2 stabilization, PAI-1/SERPINE1 inhibition, apelin-APLNR modulation, non-vasodilator KLF2 support).

The Totality Theorem: Resolution of the Closed Universe Paradox through Observer-Universe Equivalence
Authors: Yoonsu Lee
Type: Preprint
Published: 2026-08-03
Keywords: quantum gravity, observer problem, black hole information paradox, measurement problem, ER=EPR

<p>Recent work in quantum gravity has revealed that closed universes appear to admit only a one-dimensional Hilbert space, implying zero information content. The leading resolution by Harlow, Usatyuk, and Zhao (arXiv:2501.02359, January 2025), featured in Quanta Magazine (November 2025), introduces observers as external additions to restore complexity. We demonstrate that this approach is self-contradictory: it resolves a closed universe problem by opening the universe, introducing boundaries in a system defined by their absence.</p>
<p>We present a fundamentally different resolution. By proving that the open/closed distinction is itself a declaration and establishing observer-universe equivalence (O ≡ U), we derive the Totality Theorem: T = O + U = 1. The one-state result is not a paradox but a correct description of completeness: Shannon entropy H = 0 indicates full knowledge, not emptiness. We show that dimensionality itself is an artifact of partition, not a feature of reality.</p>
<p>From three relations alone — T = 1, O ≡ U, dO = −dU — and a single structural principle (the Law of Identity A = A generates the binary partition A + ¬A = 1 with unique fixed point A = ¬A = 0.5), we resolve problems across every foundational domain: the unification of the four laws of thermodynamics as facets of a single identity, the black hole information paradox, the cosmological constant discrepancy, the Collatz and twin prime conjectures, Wigner's 67-year mystery of mathematical effectiveness, and the dissolution of Gödel's incompleteness as a property of notation rather than truth. All results derive from A = A.</p>
Antidemocratic Policing in America: The Institutionalization of Historical Trauma

<p>Around the world, countries have begun reforms to align their police forces with a democratic policing <br>culture. Despite significant progress in interpreting the United States Constitution, the United States has <br>failed to fulfill one of the key aspects of democratic governance: democratic policing. Consequently, the <br>gap between law and departmental policy, and policing culture continues to widen. This study aims to <br>contribute to Forde’s theory by applying its antidemocratic framework at the institutional level to describe <br>policing practices that have received widespread attention from the media and scholars alike, and which <br>continue to widen the divide between the police and the public by exploring police misconduct through a <br>power lens of regressive antidemocratic strategies. Antidemocratic tactics and strategies must be recognized <br>for creating effective democratic policing frameworks for positive and sustainable social change. The <br>sample includes extant literature and data from exonerees. The generic qualitative inquiry was chosen to <br>explore whether the antidemocratic framework has become institutionalized by answering the research <br>question: How does Forde’s antidemocratic framework, rooted in historical trauma and political <br>demoralization, manifest in contemporary police-civilian interactions? Forde’s antidemocratic concepts—<br>nativism, social distinctions, misinformation, fear, dehumanization, and subjugation—frame this study. The <br>framework underpins the understanding of antidemocratic policing and how micro-level disempowerment <br>and macro-historical trauma (colonialism) converge in modern institutions. The primary finding is that <br>antidemocratic practices are institutionalized. Future studies on democratic policing could inform the field <br>and policymakers on whether misconduct, particularly excessive use of force, is a symptom of police <br>demoralization, and the types of antidemocratic disempowerment tactics are being leveraged against <br>innocent civilians by other criminal justice practitioners. </p>
The Ayala Ω Decision Activation Framework: Selective Decision Activation Under Equal-Budget Planning Constraints
Authors: Ayala Feliciano, Daniel
Type: Preprint
Published: 2026-08-03

<p>Abstract</p>
<p>This work presents the Ayala Ω Decision Activation Framework, a computational framework for identifying when alternative decision pathways become beneficial under constrained planning conditions. The framework is evaluated on a synthetic longmixed benchmark using exhaustive analysis, reproducible experiments, and equal-budget comparisons against nominal planning and comparator strategies.</p>
<p>The principal finding is that Ω produces selective rather than indiscriminate intervention. Under calibrated conditions, Ω modifies only a small subset of available decisions, with nearly all changes occurring in low decision-margin regions where improvements are most likely. Additional analyses compare Ω with score-matched placebo and equal-budget comparator methods, demonstrating that the observed improvements are not explained solely by additional search effort. The study also includes reproducibility materials, statistical analyses, figures, source code, and complete experimental outputs to enable independent verification.</p>
<p>The results support the conclusion that, within this synthetic benchmark, Ω functions as a selective decision-activation mechanism rather than a general optimization procedure. The work is presented as an empirical computational framework whose applicability beyond the evaluated benchmark remains an open question for future research.</p>
Humanitarian Paralysis: An Analysis of the Domestic Barriers to Aid in Sudan's Civil War
Authors: Kurzweil, Max
Type: Preprint
Published: 2024-12-05

<p>This paper examines the domestic barriers to addressing Sudan’s humanitarian crisis during the ongoing civil war, which began in April 2023. It attributes the crisis to three key factors: Sudan’s history of militarization, ethnic tensions, and authoritarian governance. These elements have compounded the humanitarian impact of the conflict, which has resulted in widespread famine, preventable deaths, and atrocities such as ethnic cleansing. While providing a brief context on international influences, the analysis focuses primarily on how Sudan’s internal dynamics, rooted in its colonial past and perpetuated by its militarized and repressive state structures, hinder effective humanitarian relief efforts and exacerbate the suffering of millions.</p>
A Structural Origin of Energy, Degeneracy, and Entropy

<p><span>Statistical mechanics traditionally begins with microscopic states, their energies, and the associated degeneracies.

<p><span>The proposed framework is based on finite architectural signatures and their associated<span class="apple-converted-space"> </span><strong>Architectural Magnitude</strong>, a positive multiplicative character defined on a four-generated free commutative monoid.

From Shock and Awe  to Hearts and Minds:  How the Iraq War Showed the Potential of Feminist Theory in a Realist World
Authors: Kurzweil, Max
Type: Preprint
Published: 2026-08-03

<p>This paper examines why the 2003 U.S. invasion of Iraq evolved into an eight-year conflict by comparing the explanatory power of offensive realism and feminist curiosity. While offensive realism explains the strategic rationale for initiating the invasion, the paper argues that feminist curiosity better explains the war's persistence by highlighting the roles of militarized masculinity, gendered social structures, and the political economy of prolonged conflict. Using the Iraq War as a case study, the research demonstrates how these often-overlooked social and economic dynamics contributed to insurgent recruitment, human trafficking, corporate incentives, and resistance to withdrawal, ultimately arguing that incorporating feminist perspectives into international relations provides a more comprehensive framework for understanding and preventing prolonged modern conflicts.</p>
Measuring Nearby Change Around One Point
Authors: Tomasz, Owsiak
Type: Preprint
Published: 2026-08-03

<p>This expository note develops a local measure of nearby change around a fixed point by comparing nearby function values f(t) with the anchored value f(x).</p>
<p>The construction begins with signed increments, shows how cancellation can hide genuine change, replaces signed differences by absolute vertical distances, converts the resulting total area into a mean gap, and finally normalizes by the window radius. This leads to</p>
<p>A_f(x,δ) = (1/(2δ²)) ∫_[x−δ,x+δ] |f(t)−f(x)| dt.</p>
<p>For an affine function of slope m, this quantity equals |m|/2 for every positive radius. At differentiable points it converges to |f′(x)|/2. When finite one-sided derivatives exist, the limit is</p>
<p>(|f′_−(x)| + |f′_+(x)|)/4.</p>
<p>The note also examines quadratic, absolute-value, square-root cusp, step-function, rapidly oscillatory, and isolated-anchor examples. In particular, for f(t)=t sin(1/t), with f(0)=0, the normalized quantity converges to 1/π despite failure of the ordinary derivative.</p>
<p>The construction is an anchored L¹ mean absolute increment normalized by radius. No claim is made that the underlying functional is new. The purpose of the note is to derive the normalization geometrically, explain its interpretation, and study its behavior in several instructive local examples.</p>
