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, …

The traditional design with cylindrical pin-fin heat sinks was used as the baseline geometry, and varying degrees of twist ranging from 0° to 60° were studied over a range of inlet velocity from 6.5 to 12 m/s (Re = 3.8 × 10 …

Ai Slop In The Generative Ai Era: Uncovering Hidden Costs For Information Quality, Trust, And Human-Centered Systems, Blenda G. Mutuma

Communications of the IIMA

The rapid proliferation of generative AI tools has fundamentally altered the volume, velocity, and perceived quality of information produced across academic and professional settings (Bommasani et al., 2021; Stanford Institute for Human-Centered Artificial Intelligence [HAI], 2025). Yet this expansion has introduced a critical and underexamined threat to sustainable information ecosystems: what this paper formally terms AI slop ; defined as AI-generated content that achieves surface-level plausibility while offering limited substantive value, accuracy, or contextual depth. At scale, AI slop degrades information quality and erodes institutional trust (Bender et al., 2021; Weidinger et al., 2021). More critically, it generates what this …

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.

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 …

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.

Incipient Buckling Detection Using Nonlinear System Identification Algorithms: A Comparative Study, Raymond Andrew Swartz, Padmanabh Shridhar Desai

Michigan Tech Publications

Structural health monitoring detects and characterizes damage to predict failure, but failures like buckling, which lack signs of damage, are harder to detect. Direct load measurement is costly and complex, especially for dead loads requiring copious sensors and data acquisition hardware. Vibration-based detection is a good alternative because it infers global structural characteristics with fewer sensors. This paper presents a structural health monitoring approach for the detection of incipient buckling in structures due to excessive load conditions. Existing nonlinear modeling algorithms available in commercial software platforms, such as MATLAB and other open-source toolboxes, are leveraged to make this method potentially …

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 …
