Critical Assessment On Challenges And Advances In Coal Pillar Strength Estimation Techniques: A Focus On Geological Discontinuities, Abhishek Kumar Singh, Sahendra Ram

Journal of Sustainable Mining

Accurate estimation of coal pillar strength is essential for ensuring safety and operational efficiency in underground mining. Current assessment methods often face limitations in addressing time-dependent failure mechanisms, geological discontinuities, and dynamic loading conditions. This paper identifies future research directions aimed at enhancing the reliability of pillar strength evaluations. One important focus is the development of advanced numerical models that account for time-dependent behaviours such as creep and fatigue. Incorporating multi-scale modelling techniques, which connect micro-scale material responses to macro-scale structural performance, may lead to more precise predictions. The integration of real-time monitoring systems measuring stress, deformation, and environmental factors …

Comparing Text Score Strategies For Online Music Making, Craig Pedersen, Lindsay R. Vickery, Stuart James

Journal of Network Music and Arts

This paper investigates a range of approaches to using text scores in online and networked music performance, focusing on their alignment with strategies proposed by Wilson (2020) for aesthetic and technical approaches to networked music performance. Text scores, emerging from the experimental music movement of the 1960s, communicate musical ideas through words rather than traditional notation, taking instructional, allusive, and hybrid forms. Although there are many aesthetic and pragmatic approaches to text score composition, the temporal openness of many such works makes the medium well-suited to the latency-challenged practice of telematic performance. The study evaluates four text scores—Craig Pedersen’s July …

Listening Ahead Ever So Slightly, Chris Chafe, Mike Dickey

Journal of Network Music and Arts

This paper presents a novel packet loss concealment system called “Regulator,” designed for interactive network audio applications, particularly server-mediated “jam rooms” in the cloud, where large ensembles of musicians perform together synchronously. The system addresses the critical challenge of maintaining continuous high-quality audio output while minimizing latency penalties in unreliable network environments including Wi-Fi. The Regulator architecture combines four core components: a central Regulator class orchestrating packet loss concealment operations; a BurgAlgorithm class implementing maximum entropy autoregressive prediction to reconstruct missing audio samples; a Channel class providing per-channel independent modeling for multi-channel streams; and a RegulatorWorker class offering asynchronous processing …

Pulse Before Sound: Reimagining Presence And Liveness In Telematic Music Performance Through Midi-Native Collaboration, Matt C. Bray

Journal of Network Music and Arts

Telematic Music Performance heralds a new paradigm for human creativity, seeking to extend the practical limits imposed by physical co-presence and to permit the cooperative, simultaneous creation of music among geographically remote collaborators. This paper examines how MIDI-native interaction provides a structurally robust alternative to audio-centric telematic systems constrained by latency, bandwidth, and waveform fidelity. Drawing on practice-led research, including over 34 hours of documented improvisation across 91 networked sessions in the SHOALZ series—a longitudinal Telemidi performance research initiative (2022–2024)—the study examines how the Telemidi system employs MIDI as a primary substrate for remote musical collaboration by establishing a synchronized …

Toward The Significance Of Crevasse Orientation In Low And High Crevassed Regions On The Kennicott Glacier, Alaska, Usa, Claire A. Sturm

DePaul Discoveries

Supraglacial landforms serve as potential indicators of underlying bedrock morphology and glacier dynamics. The distribution and morphology of crevasses are closely associated with stress fields and ice-flow regimes, representing processes of stable glaciers, in contrast to their reduced occurrence in stagnant or receding ice masses. The orientation and density of crevasses influence a glacier’s ability to absorb solar energy, as they facilitate movement of meltwater down to subglacial rivers. Beyond the meltwater acting as a lubricant for basal sliding, the slope of the bedrock further impacts the local velocity and ice deformation of a glacier. The study of ice-fracturing mechanics …

Clearing The Air: Tracking Spatial And Temporal Pm2.5 Variability Along A Biking Transect In Chicago, Beau R. Rass

DePaul Discoveries

Fine particulate matter (PM₂.₅) poses significant risks to human health and disproportionately affects marginalized communities in urban environments (World Health Organization [WHO], 2021; Tessum et al., 2021). Using low-cost mobile sensors, this study explored spatiotemporal PM₂.₅ concentration patterns along a north–south transect of Halsted Street in Chicago. A 2B Technologies Portable Aerosol Monitor (PAM) mounted on a bicycle was used to continuously record PM₂.₅ concentrations with associated GPS coordinates at approximately two-second intervals during 16 sampling events between 08-12-2025 and 10-05-2025. PM₂.₅ concentrations did not differ significantly among the South Side, West Loop, and North Side regions, contrary to the …

Credential-Isolation Protocol For Autonomous Ai Coders In Multi-Tenant Repositories, Gustavo Matthew Assuncao

Defensive Publications Series

Autonomous AI coding agents that branch, commit, and push on behalf of a fleet invert the assumption behind conventional continuous-integration (CI) secret handling. CI secret models deliver credentials through environment variables and rely on log masking, because they assume the untrusted principal is a human operator or an external attacker reading build logs — not the code author itself. When the code author is a large-language-model (LLM) agent that runs in-process with the orchestrator, inherits its environment, and can emit arbitrary files and network calls under an auto-accept edit mode, an environment-delivered token becomes an open exfiltration channel and log …

Defensive Publications Series

1. This document outlines a standardized, closed-loop biological framework for manufacturing high-tensile structural fibers capable of supporting high-altitude or orbital infrastructure. The pipeline eliminates the requirement for traditional heavy industrial refinery infrastructure by utilizing a re-engineered multi-organism bacterial substrate. Through co-cultured metabolic pathways, engineered microorganisms systematically convert base carbon inputs into volatile propane and ammonia gases. These gases are captured, reacted via ammoxidation, and carbonized to generate advanced carbon-fiber matrices suitable for aerospace tether deployments.

Pipeline For Llm Refinement With Expert Routing, Consensus, And Impact Attribution, Saloni Priya

Defensive Publications Series

Systems and methods can refine LLM outputs through a pipeline architecture that integrates human expert feedback. This pipeline may feature a dynamic routing engine to assign detected errors to qualified experts, an adaptive quality-weighted consensus engine to validate proposed corrections, and an impact attribution engine to measure the value of contributions. These components can operate in a feedback loop to identify, correct, and reintegrate validated knowledge. This process can be used to ground future LLM generations with curated information, potentially affecting the factual accuracy and reliability of model outputs in a scalable manner.

Policy-Graph Audit Method For Algorithmic Collusion Detection In Multi-Agent Pricing Systems, Anonymous

Defensive Publications Series

A computer-implemented audit evaluates collusion risk in multi-agent reinforcement-learning pricing systems by analyzing the full counterfactual structure of trained policies rather than only observed price traces. Trained policies are frozen into deterministic greedy action mappings over a discrete joint market state space. A deterministic successor mapping is computed for each joint state to form a directed functional graph with one outgoing edge per state. The graph is decomposed into attractor cycles and basins of attraction that partition the state space. Each attractor is assigned an elevation score based on mean cycle price relative to reference Nash and joint-profit-maximizing price levels, …

Building Consumer Trust In Short-Term Rentals: A Literature Review On Factors Influencing Consumer Booking Motivations And Trust Formation, Alyssa N. Thornton, Kiyan Shafieizadeh

ICHRIE Research Reports

This study synthesizes existing research on consumer trust formation and booking motivations in short-term rental (STR) platforms through a systematic literature review. Drawing on 19 peer-reviewed studies published between 2015 and 2025, the review examines how trust-building cues and motivational factors jointly influence consumer booking decisions in peer-to-peer accommodation contexts. Using a thematic analysis approach, the findings reveal five dominant themes: visual and aesthetic cues, host attributes, reviews and reputation mechanisms, economic and functional motivations, and host–guest interaction. The results highlight the central role of visual presentation and social signals in reducing perceived risk and fostering trust, while economic and …

Guests Attitude And Purchase Intention Towards Hotel Brand Extension, Daegeun Kim, Eun-Kyong (Cindy) Choi, Tanya Ruetzler, James Taylor

ICHRIE Research Reports

Brand extension is widely used among firms and hotels to launch new products using their parent brand name, making it important for practitioners to understand which factors influence consumers' attitude toward brand extension (ATT). This study investigated the role of consumer brand identity (CBI) in guests' attitude leading to purchase intention (PUR) for hotel vacation rentals. Findings suggest that CBI was a positive antecedent of perceived fit (PF) and tie (PT), which positively influenced ATT. Additionally, parent brand conviction and quality were identified as factors that positively influenced ATT and led to PUR. As the first study on hotel vacation …

Provenance-Tiered Database Serve-Override Cms Over Immutable Container Assets, Gustavo Matthew Assuncao

Defensive Publications Series

This document discloses, as enabling public prior art, a content-management mechanism that layers a database-backed content overlay on top of an immutable set of static assets baked into a container image. A single GET-only "serve-override" resolver, keyed on the tuple (slug, locale, audience), returns a published database row when one exists and otherwise falls through to the baked file. The image is the read-only floor; the running pod is never written at request time. Two structural properties are central. First, a reserved-slug set — authentication, session, and OAuth callback paths — is never overridable, so security-critical routes always execute baked, …

Deterministic Stateless Digital-Twin Rendering Of A Live Ai-Agent Workforce With Ledger-Windowed Replay, Gustavo Matthew Assuncao

Defensive Publications Series

This document discloses, with enabling detail sufficient for a person of ordinary skill to build it, a method and system for rendering a live, game-like visualization of a workforce of autonomous software agents in which every visual property is a pure deterministic function of operational records and the renderer holds no game state. Avatar state resolves by an active-work-wins-over-the-clock precedence; deterministic hashing places desks and picks palette swatches with a bounded collision-walk over the true floor grid; an ambient night tint is computed from the share of off-shift ("dreaming") agents plus the server hour, never a viewer's clock; ledger events …

Modality-Blind, Local-First Handwriting Evidence Ingestion With Server-Side Image Rejection And Absence-Never-Denies Gate Equity, Gustavo Matthew Assuncao

Defensive Publications Series

Adaptive-learning platforms increasingly want to admit analog work — a photographed page of handwritten work — as assessment evidence alongside typed and spoken answers. The obvious implementation is corrosive: it uploads a child's handwriting image to a server, applies a single blanket consent posture across every capture surface, and — most insidiously — lets the presence of a shiny new evidence channel become an implicit penalty for the learner who has no camera, no printer, or no wish to photograph their work. This disclosure describes a mechanism that structurally refuses all three failure modes. First, the client performs deterministic on-device …

Fail-Closed Multi-Backend Artifact Gate With Reject-Biased Union Resolution And A Single Chokepoint, Gustavo Matthew Assuncao

Defensive Publications Series

This publication discloses, with enabling detail, a fail-closed governance gate that is invoked at every path capable of creating, registering, or enabling a governed unit of work — a new application, a new game, or a large ("big-task") change. The gate refuses to let creation proceed unless a mandated set of governance artifacts (an idea brief, a purpose statement, a design, a cost model, an implementation plan, a deployment runbook, and a live tracker) is proven to exist. The novelty is not "check that files exist." It is how presence is resolved. A mandated artifact may live in any one …

Owner-Gated Conversation-To-Cognition Ingestion With Lazy Persona Activation And Crash-Restorable Process Table, Gustavo Matthew Assuncao

Defensive Publications Series

This publication discloses, in enabling detail, a mechanism that couples a synchronous conversational assistant (a chat surface a human talks to and gets an immediate answer from) to an asynchronous autonomous-agent runtime (a background "persona" that perceives, reasons, plans, acts, and reflects on its own schedule) through a single caller-trust-scoped ingestion valve. Every conversational turn is stamped with an access mode denoting the trust of the caller. The valve admits a turn as cognitive work only when the access mode denotes the resource owner; turns from untrusted (guest) callers are dropped at the valve so untrusted conversation never becomes autonomous …

Dual-Path Work Delivery Into An Agent Cognitive Loop, Gustavo Matthew Assuncao

Defensive Publications Series

This publication discloses, in enabling detail, a dual-path protocol for delivering a unit of work into an autonomous agent's cognitive loop and for verifying, out of band, that the work does not silently stall. A fast path enqueues a work item in-process onto a resident attention queue by resolving the engine from a shared carrier (a config bridge object, else a last-resort global handle) and calling a plain function; this path is deliberately lossy — it never retries, never demands an acknowledgement, and fails soft to false when the engine is not resident. Correctness is not entrusted to the fast …
