By highlighting issues such as sustainability, inclusivity, and privacy, the …

Review Of Land In Libraries: Toward A Materialist Conception Of Education, Anna Z. Szapiro

Journal of Contemporary Archival Studies

Extractive practices of colonial land theft and environmental exploitation have produced intolerable global conditions leading to climate collapse. As the information field grapples with its culpability in colonial violence and climate change, Lydia Zvyagintseva and Mary Greenshields’s incisive Land in Libraries: Toward a Materialist Conception of Education draws contributions from practitioners in the United States and Canada to chart a way forward. Through historical analysis, case studies, critical theory, and autoethnography, authors in this volume take up land – and our relation to it – as the epistemological catalyst for systemic change. At once austere critique and lyrical contemplation, Land …

Geochemistry Of Crusts In Palaeontological Deposits, Taphonomic Settings In An Upper Pleistocene Cave Site (San Teodoro, Sicily), Gerlando Vita, Luca Sineo, Francesco Armetta, Maria Luisa Saladino

International Journal of Speleology

The mineralogical and geochemical composition of cave sediments provides crucial insights into past climatic and biological dynamics. This study investigates the authigenic crusts of San Teodoro Cave (Sicily), a key Upper Pleistocene palaeontological site, through a multi-analytical approach.The cave hosts two superimposed phosphatic crusts, separated by sterile sediment, reflecting shifts in depositional and post-depositional conditions. Our analyses reveal a complex mineral assemblage consisting of calcite, aragonite, and various phosphate phases. Calcite is the dominant phase in the older crust, whereas the presence of aragonite in the younger brown crust likely indicates periods of increased aridity, potentially corresponding to conditions during …

Today, HDD (hard disk drive) manufacturers are increasingly turning to HAMR (heat-assisted magnetic recording) technology to increase the capacities of the HDDs. They are discovering that for this technology to work well, the environment inside the hard disk drive has to be very clean, as free from contaminants and with as little outgassing as possible. Outgassing is known to be one of the major contributors to HAMR DWC (degrade write capability) and today for the latest HAMR drives, one main source of outgassing comes from the FIPG (formed-in-place-gasket). The FIPG is often, if not always, applied onto the cover. Besides …

The Authority Tone Risk In Ai Assistants: Detecting When Confident Language Outruns Evidence, Pranav Bhatnagar Mr

Defensive Publications Series

In production environments, the failure mode is rarely obvious hallucination. The more dangerous pattern is quieter: the model delivers a clean, decisive answer in situations where the underlying support is thin, conditional, or incomplete. The wording is polished. The structure is confident. Users move forward. Only later does the gap surface. That gap between how certain the system sounds and how much evidence actually exists is where trust begins to drift off course. This paper formalizes that risk as Authority Tone Risk (ATR) and introduces a practical detection layer built for real deployments. The framework measures assertiveness signals against evidence …

The Ai Hesitation Signal: Detecting When Models Know But Don’T Say, Pranav Bhatnagar Mr

Defensive Publications Series

In production systems, capability loss often hides behind polite uncertainty. Models that are technically able to provide useful, specific guidance sometimes respond with unnecessary hedging, generic deferrals, or softened language that reduces operational value. The system is not wrong. It is holding back. This paper defines that pattern as the AI Hesitation Signal (AHS) and treats it as a measurable behavioral condition rather than anecdotal user frustration. The proposed framework identifies situations where the assistant’s expressed uncertainty is disproportionate to the task context and available support. By jointly analyzing linguistic hesitation markers, response specificity, contextual risk posture, and historical capability …

The Ai Handicap Effect: When Systems Underperform To Appear Safe, Pranav Bhatnagar Mr

Defensive Publications Series

In many real deployments, the failure is not that the model is reckless. The failure is that the model becomes too cautious to be useful. As alignment layers, guardrails, and policy filters stack up over time, capable systems begin to hedge, refuse, or dilute responses in situations that are objectively low risk. Productivity drops. Users work around the system. Trust erodes quietly. This paper defines that pattern as the AI Handicap Effect. The work introduces a practical detection approach that identifies when safety mechanisms begin to suppress legitimate capability beyond acceptable thresholds. Instead of treating refusals or hedging as automatically …

Ai Response Consistency Checker Detecting Cross-Response Contradictions In Generative Systems, Pranav Bhatnagar Mr

Defensive Publications Series

Generative AI systems are increasingly deployed in environments where users rely on multiple responses across sessions, prompts, or conversational turns to inform decisions. While individual outputs may appear internally coherent, large language models can produce subtle or overt contradictions when queried repeatedly on related topics, especially under context variation or prompt rephrasing. These cross-response inconsistencies can degrade user trust, propagate analytical errors, and introduce governance risks in enterprise AI deployments. Traditional validation approaches typically evaluate single responses in isolation and therefore fail to capture this emerging class of reliability failure. This disclosure introduces an AI Response Consistency Checker, a supervisory …

Configurable Vehicle Ingress And Egress Safety Management System, Anonymous

Defensive Publications Series

A system is provided to ensure passenger safety during the boarding and departing phases of a vehicle trip, particularly for rideshare and fleet applications. The system allows a passenger to pre-configure safety preferences—such as seat belt fastening delays, sensor-based confirmation of occupancy, and departure clearance buffers—via a mobile application. These preferences are communicated to the vehicle and driver, potentially influencing the ride-matching process. The system further manages vehicle motion post-egress by enforcing delays, distance-based clearance verification via external sensors, and restricted vehicle performance (acceleration/noise) for an initial travel segment to protect the departing pedestrian.

On The Jordan-Chevalley-Dunford Decomposition Of Certain Classes Of Operators And Convergence Of Their Normalized Power Sequences, Renu Shekhawat

Doctoral Theses

The classical Jordan–Chevalley decomposition expresses a matrix A ∈ Mn(C) as a unique commuting sum A = D + N, where D is diagonalizable and N is nilpotent. Although this decomposition is algebraic in origin, it encodes significant spectral information and, as shown by Nayak, has an important analytic consequence: the convergence of the normalized power sequence {|A^n|^ 1/n }n∈N ; |A| := (A∗A)^1/2 . In this thesis we study Jordan-Chevalley–type decompositions in infinite-dimensional settings and their connection with the convergence behaviour of normalized power sequences. In particular, we discuss this phenomenon for Dunford’s spectral operators and compact operators on …

Mscl-X: Meta Supervised Contrastive Learning With Gaussian Prototypes For Robust Few-Shot Open-Set Modulation Classification, Emmanuel Mawuli Agbator

Theses and Dissertations

Automatic modulation recognition has found its way into the core modern-day wireless communication systems whereby intelligent receivers estimate signal formats without any prior coordination with the transmitters. Challenging situations arise in any working radio frequency environment for the conventional modulation recognition systems due to insufficient labeled data, rapidly fluctuating channel conditions, and appearance of plenty other unseen modulation types. Taken together, these challenges raise questions concerning the ability to institute learning frameworks that could perform well on few-shot and open-set conditions. Hence the thesis attempts to address the same by proposing two complementary learning-based frameworks for few-shot open-set modulation recognition …

Influence Of Plasticizer Type On The Structure And Drug Release Characteristics Of Lm-Pectin Hydrogels, Banu Kocaağa, Fatma Seni̇ha Güner

Turkish Journal of Chemistry

This study investigated the effects of different plasticizers—castor oil (CO), polyvinylpyrrolidone (PVP), and polyethylene glycol (PEG) with varying molecular weights (MWs)—on the structure and drug-release performance of low-methoxyl pectin (LM-pectin) hydrogels. Theophylline was used as a model drug to evaluate release behavior under physiologically relevant conditions. The incorporation of plasticizers modulated polymer–polymer interactions, swelling behavior, and thermal properties, thereby affecting drug-release kinetics. CO, a hydrophobic triglyceride, created microdomain-induced diffusion pathways; PVP, containing water-affinitive lactam units, facilitated moisture-driven plasticization; and PEG (MW 400/1000/1500), with hydroxyl-terminated chains, established hydrogen bonds with pectin. Structural analyses (FTIR and DSC) revealed that CO disrupted pectin …

Turkish Journal of Chemistry

A multiscale computational investigation integrating density functional theory (DFT) and molecular dynamics (MD) simulations was conducted to elucidate the mechanisms through which sulfur-containing donor molecules stabilize the photoactive α-phase of formamidinium lead iodide (FAPbI3) perovskites. The binding energetics, charge-transfer behavior, and hydrogen-bonding interactions of thiourea (TU), thiosemicarbazide (TSC), thiocyanate (SCN–), and diethyldithiocarbamate (DTC) were systematically analyzed. DFT results revealed pronounced Pb–S coordination and multidentate hydrogenbonding, with binding energies following the trend SCN–>TSC>DTC>TU. Thermodynamic analysis demonstrated that these additives lower the Gibbs free energy difference, thereby stabilizing the black α-phase, with TSC, TU, and to a lesser extent …
