Improving Security Policy Validation In Distributed Systems Using Attack Graph Simulations, Zaid J. Al-Araji, Balqees Talal Hasan, Fahad Ahmed Shaban, Ali Khairi Al-Toohafi, Hussein M. Farhood, Alaa Al-Dabbagh, Omar Nazar Hamdoon

Al-Bahir

Validation of security policies in distributed systems is difficult because rules are heterogeneous, interact in non-obvious ways, and static checks often overlook multi-stage attacker chains. We offer a unified framework to translate real policies, and in parallel give visibility into policy-aware attack graphs (PAAGs), then we evaluate them using deterministic as well as probabilistic simulations, with Monte Carlo (MC) included. The policies are naturally embedded in the construction; firewall semantics deny or remove exploit edges, RBAC limits privilege transitions, and IDS/IPS lower the success likelihood of edges, so the resulting graph reflects both the vulnerability surface and the enforcement posture. …

Al-Bahir

Operating at high temperatures is one of the key factors affecting the performance of photovoltaic systems. In hot-arid climates, the temperature is typically extremely high. In this study, the experimental performance of two passive cooling systems, phase change materials (PCMs) and zeolite X13-CaCl₂, was comparatively assessed to improve the performance of cadmium telluride photovoltaic panels under the same real operating conditions in Baghdad, Iraq. An improvement of approximately 8.5% in electrical conversion efficiency (i.e., the percentage increase compared to the reference system and not the actual value) was achieved, with a decrease in temperature of approximately 12 °C being recorded …

The Nine-Block Pyramid: A Structural Framework For Cultivating An Ai Adoption Mindset Culture At Enterprise Scale, Ahmad Masri

Communications of the IIMA

Enterprise artificial intelligence (AI) adoption is nearly universal in name but shallow in practice: a large majority of organizations now use AI in at least one business function, yet only a small minority have scaled it enterprise-wide, and leadership commitment rather than technology is repeatedly cited as the binding constraint. This conceptual paper argues that AI adoption is fundamentally a mindset-culture problem, not a tooling problem, and proposes a nine-block pyramid as a practical framework describing a sequencing heuristic, anchored in established organizational-behavior theory, for the cultural conditions an enterprise should build to sustain an AI adoption mindset: (1) Enterprise …

Comparative Analytical Study Of Titanium Alloys By Libs, Xrd, And Eds, Hyder A. Salih, Sabah N. Mizhir, Khaleel I. Hassoon, Nisreen Kh. Abdalameer, Mona Niroozad

Journal of Applied Sciences and Nanotechnology

Titanium alloys (TiAs) have significant applications in engineering and technological purposes but often demand inclusive characterization due to their different components and properties. While previous LIBS investigations on Ti alloys have demonstrated its capability for elemental identification, they have not systematically explored its application for rapid sorting and recycling of industrially relevant titanium alloys with complex compositions. Our work specifically addresses this gap by applying LIBS to differentiate and classify Ti alloys with varying alloying elements. Pure (T0) and two commercial titanium alloys (T1 and T2) have been investigated using LIBS, XRD, and EDS techniques for fast and exact identification, …

Integration Of Freshness Monitoring And Active Packaging Technologies For Aquatic Products, Maria Ali, Abdul Waheed Ghanghro, Bheem Raj Serani, Mahrukh Zakir

Journal of Food and Drug Analysis

Aquatic products are nutritionally valuable but highly perishable, with quality loss driven by microbial spoilage, biochemical changes, including total volatile basic nitrogen (TVB-N), trimethylamine (TMA) and histamine, and physicochemical deterioration, including lipid oxidation, gas production and texture loss. Conventional packaging slows these processes but does not report real-time freshness. This review analyzes how active packaging (antimicrobial, antioxidant, enzyme-inhibiting, and oxygen-scavenging systems, including bio- and nanocomposites) can be combined with freshness monitoring technologies (colorimetric/pH indicators, gas sensors, biosensors, and digital tools such as radio frequency identification (RFID) and Internet of Things (IoT) systems) specifically for fish, shrimp, and mollusks. We first …

Client-Side Dom-Based Orchestration Of Generative Ai Meeting Artifacts, Mansi Sawant

Defensive Publications Series

In enterprise video conferencing environments, capturing actionable engineering artifacts such as bug reports, architecture diagrams, or task assignments often requires users to manually context-switch across multiple browser tabs and applications. Existing third-party artificial intelligence (AI) agents attempt to address this by ingesting meeting transcripts via backend APIs, but this approach introduces security risks by transmitting confidential meeting data to external servers and requiring highly-privileged OAuth scopes for cross-application execution. The present disclosure describes a client-side autonomous orchestrator that operates entirely within the user's authenticated browser session. The orchestrator utilizes front-end robotic process automation and Document Object Model (DOM) manipulation to …

System And Method For Local Venue User-Generated Content Registration, Affinity-Sensed Curation, And Revenue-Shared Broadcast Pickup, Eric Zavesky

Defensive Publications Series

Adaptive Media Content Recommendation Based On Temporal Physiological States, Karl Joseph Weinmeister

Defensive Publications Series

This publication describes a media recommendation system that conditions content selection on a listener’s temporal physiological state rather than on external context alone. A biometric-sensing wearable device streams heart rate (HR), heart-rate variability (HRV), and inertial (e.g., accelerometer or gyroscope) data to a host media device, which buffers the multi-stream time series over a rolling look-back window. The buffered series is decomposed into a personalized seasonal component (circadian rhythms, baseline metabolic variation, historical resting-heart-rate zones, etc.) and a trend component that outputs the velocity and acceleration of the physiological state. A context classifier fuses biometric and motion signals to classify …

Multi-Cycle Dynamic Ir-Drop Prediction For Power Delivery Networks Using A Shared-Weight Encoder-Decoder With Convolutional Recurrence, Prateek Pendyala

Defensive Publications Series

Dynamic IR-drop, a voltage drop reflecting current (I) through resistance (R), has become a significant operational constraint in the power delivery network (PDN) of an integrated circuit.  A transient matrix solver can take upwards of 6-12 hours to verify one engineering change order (ECO).  Separately, a frame-based neural network may miss voltage deficits that build across consecutive clock cycles.  To address these limitations, this a prediction method feeds per-cycle power tensors through a shared spatial encoder.  From there, a convolutional long short-term memory (ConvLSTM) temporal core carries voltage history from cycle to cycle.  A shared spatial decoder then reconstructs a …

Gci-Vabc-R+ Continuous Acoustic-Inertial Bio-Purification Engine, Michael Victor Caldwell Mr.

Defensive Publications Series

Elevated levels of Lipoprotein(a) [Lp(a)] represent an independent, genetically determined causal risk factor for cardiovascular disease and aortic stenosis, affecting approximately 20% of the global human population. Current therapeutic interventions face severe trade-offs: pharmacological antisense oligonucleotides (e.g., Pelacarsen) have demonstrated sub-threshold event reduction in large-scale outcomes trials (Lp(a)HORIZON) due to depth-of-lowering limits (~72–80%), whereas existing apheresis platforms non-selectively deplete all Apolipoprotein B (ApoB) particles via non-specific adsorption. This disclosure details the full bench-scale prototype specifications, fluid dynamics models, electrical schematics, and testing protocols for the GCI-VABC-R+ Research Engine.

The GCI-VABC-R+ integrates Dean-flow secondary inertial focusing, high-frequency Bulk Acoustic Waves (BAW), …

Architectural Specification Of A Local Multi-Scale Contour For Stable Recursive Self-Improvement, Volodymyr Kotegov

Defensive Publications Series

This document describes a practical architecture for stable recursive self-improvement limited to programming, algorithms, and mathematics. The system runs as a bare core and does not require broad world knowledge or data-center resources. It is designed for 1 to 5 high-end local workstations (Mac Studio class or equivalent with 128–192 GB unified memory). The design combines aggressive evolutionary search with strong conservative safeguards: multiple time scales, a shadow reference copy, orthogonality based on execution traces, an immutable control core, and specification changes that depend on measured success density.

A Health Card Is Not Healthcare Why Coverage Does Not Always Become Care And How Institutions Can Close The Gap, Deepak Aggarwal

Defensive Publications Series

Universal healthcare is usually measured through two questions: can people obtain the care they need, and can they afford it without financial hardship? Both matter. Neither tells us whether care actually reached the patient.

A person may hold a health card. The treatment may be covered. The ambulance, hospital, specialist and payer may each follow their own rules correctly. Yet the patient may still wait too long, arrive at a hospital that cannot treat them, or be lost between institutions.

This paper examines that gap through Decision Engineering™. It follows a person suffering a heart attack along the Decision Integrity …

Caldwell Neuro-Clearance Super-Engine (Cncs-1.0) A Unified Multi-Physics Research Reactor For Non-Thermal Clearance Of Neuro-Toxic Aggregates In Synthetic Tissue Phantoms, Michael Victor Caldwell Mr.

Defensive Publications Series

Current neurodegenerative research lacks an integrated benchtop engine capable of simulating the mechanical, electrokinetic, and acoustic parameters required to clear proteinaceous aggregates (Tau tangles, Amyloid-$\beta$ oligomers, and $\alpha$-Synuclein fibrils) from dense extracellular matrices.

CNCS-1.0 fills this gap by coupling acoustic streaming, resonant microbubble shear, amplitude-modulated radiofrequency destabilization, and electrokinetic transport into a single, temperature-locked PEEK-1000 micro-vortex chamber. The system reduces simulated Interstitial Fluid Pressure (IFP) from $25\text{ mmHg}$ down to $\le 6\text{ mmHg}$ in tissue phantoms while driving unidirectional magnetophoretic and acoustic aggregate clearance—all without exceeding a $\Delta T$ of $+0.4^\circ\text{C}$ in the biological matrix.

High Tunnel Pollinators, Miranda L. Jones, Sheriden Hansen, Kelsey Graham, Robert Nelson Schaeffer, Brent Black

All Current Publications

High tunnels are used to extend the growing season. Unlike greenhouses, high tunnels are semi-permanent and not heated or cooled by a climate-control system. Instead, they use plastic sheeting to trap solar heat, allowing for season extension in temperate climates around spring and fall. Bee pollination can improve yields for several valuable crop species grown in high tunnels. Because high tunnels are largely enclosed, bees are typically released and managed within the structure. This fact sheet provides information on how to obtain and manage bee pollinators in high tunnels.

Toxicity Ahead: Forecasting Conversational Derailment On Github, Mia Mohammad Imran, Robert Zita, Rahat Rizvi Rahman, Preetha Chatterjee, Kostadin Damevski

Computer Science Faculty Research & Creative Works

Toxic interactions in Open Source Software (OSS) communities reduce contributor engagement and threaten project sustainability. Preventing such toxicity before it emerges requires a clear understanding of how harmful conversations unfold. However, most proactive moderation strategies are manual, requiring significant time and effort from community maintainers. To support more scalable approaches, we curate a dataset of 159 derailed toxic threads and 207 non-toxic threads from GitHub discussions. Our analysis reveals that toxicity can be forecast by tension triggers, sentiment shifts, and specific conversational patterns.We present a novel Large Language Model (LLM)-based framework for predicting conversational derailment on GitHub using a two-step …
