Tone Mapping Using Negative Values To Represent Luminance Below Reference Black, Yannis Guyon, Nathan Gauër Dec 2025

Tone Mapping Using Negative Values To Represent Luminance Below Reference Black, Yannis Guyon, Nathan Gauër

Defensive Publications Series

High Dynamic Range (HDR) tone mapping traditionally extends brightness above a reference white value but uses a fixed floor of zero for black, which maps to a display's minimum luminance setting. This limits creative control over shadow detail by content creators, e.g., the ability to choose blacks deeper than those for which legacy content was mastered or to choose to keep content at a reference black regardless of a display's minimum luminance setting. This disclosure describes a method for extending the HDR tone-mapping range to include negative values, allowing for greater flexibility in tone mapping shadows. In this approach, the …

What Does Graptolite Origination And Extinction Reveal About The Cause Of The Late Ordovician Mass Extinction?, Charles E. Mitchell, H. David Sheets, Michael J. Melchin, Chris Holmden

Computer and Data Science Faculty Publications

Assesses the macroevolutionary turnover of paleotropical planktic graptolites during the Late Ordovician Mass Extinction (LOME) via automated sequencing and capture-mark-recapture modeling. Graptolites exhibited a succession of turnover pulses (sensu Elizabeth Vrba) that were coincident with the main phases of the Hirnantian glaciation and during which the Diplograptina experienced declining metapopulation size, elevated extinction, zero species originations, and ultimately, complete extermination. Concurrently, the Neograptina (latest Katian temperate zone immigrants) exhibit pulses of both extinction and adaptive radiation. Thus, the LOME involved intense species selection and the wholesale alteration of the clade diversity structure of a major element of the zooplankton. The …

Linking Shoreline Change, Environmental Forcings, And Sedimentological Resilience In Nourished Beaches Of Cape May And Wildwood, New Jersey, Usa: A Multi-Decadal Synthesis, Divomi Balasuriya, Greg Pope

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Beach nourishment is a widely used strategy to mitigate coastal erosion, yet its long-term geological impacts remain poorly understood. This study provides a multi-decadal synthesis of shoreline change and sedimentological evolution on the nourished beaches of Cape May and Wildwood, New Jersey, USA. Using shoreline positions from 1991 to 2024, we identify contrasting trajectories: Wildwood exhibits ‘persistent transition’ with severe northern erosion (EPR: −10.0 m/yr) feeding southwards accretion, while Cape May demonstrates a ‘managed equilibrium’ with widespread accretion (mean EPR: +1.15 m/yr). Wave energy correlations account for less than 15% of shoreline variability, indicating natural drivers have been superseded by …

A Systematic Study Of Passkey User Experience Consistency, Bernhardt Ramat Dec 2025

A Systematic Study Of Passkey User Experience Consistency, Bernhardt Ramat

Theses and Dissertations

Passkeys have emerged as a more secure authentication method than passwords, providing a passwordless alternative resistant to phishing and credential theft attacks. Despite their growing adoption, a systematic study into the user experience of passkeys across various websites has yet to be conducted. Usability heuristics suggest that users transfer their expectations from one product to another, and therefore, inconsistencies in passkey deployments can increase cognitive load, resulting in frustration and possible rejection. To address this knowledge gap, this paper presents a comparative analysis of the external functional consistency of the passkey user experience across 111 websites. Our research reveals that …

Quantifying Dna Groove Binding Dynamics Of Netropsin Using Optical Tweezers, Jacob Mcnally

Honors Program Theses and Projects

Netropsin is a small molecule that binds to the minor groove of DNA and serves as a model scaffold for DNA-minor groove binding anticancer drugs. Understanding how Netropsin interacts with DNA under mechanical stress is important for characterizing how similar molecules function in biological environments. In this work, we used dual-beam optical tweezers to study how Netropsin binding affects the mechanical behavior of single DNA molecules under applied force. Individual DNA molecules were held under controlled forces while Netropsin was introduced at varying concentrations. Constant-force measurements were used to probe binding dynamics; however, we found binding occurred too rapidly to …
