Systems and models for secure fallback authentication
Fallback authentication (FA) techniques such as security questions, Email resets, and SMS resets have significant security flaws that easily undermine the primary method of authentication. Security questions have been shown to be often guessable. Email resets assume a secure channel of …

Efficient Routing in the CityMesh Decentralized Fallback Wireless Network
… this risk, CityMesh proposes a decentralized fallback wireless network that leverages existing Wi-Fi devices, such as access points (APs), in buildings to maintain essential connectivity during outages. However, achieving scalable and reliable message delivery in such a network, without …

Exploring the Paradoxical Role and Experience of Fallback in Developmental Theory
… than originally thought and may involve fallback to earlier stages in certain circumstances. Further, fallback to an earlier stage of meaning-making may prompt learning that can lead to growth. The purpose of this study, which used grounded theory methodology, was to examine the …

On Optimizing Transactional Memory: Transaction Splitting, Scheduling, Fine-grained Fallback, and NUMA Optimization
… to solve the granularity of the software fallback path of best-efforts HTM. It provide an efficient and precise technique for HTM-STM communication such that HTM is not interfered by concurrent STM transactions. In addition, the added overhead is marginal in terms of space or execution …

The Use of Fallback Foods in a Population of Black Handed Spider Monkeys at Runaway Creek Nature Reserve, Belize
… rely on less-preferred food types, called fallback foods. Periodic reliance on fallback foods has led, in some cases, to the evolution of morphological traits geared towards their exploitation. However, in species without these traits, fallback foods may instead beget behavioural …

Applying Source Level Auto-Vectorization to Aparapi Java
… are then run on OpenCL capable hardware with a fallback path in the Java thread pool to ensure code reliability. This work takes advantage of the knowledge of independence of the parallel sections of code to automatically modify the Java thread pool fallback path to include the vectorization …

Account Recovery Methods for Two-Factor Authentication (2FA): An Exploratory Study
… equation, the present study determined that a fallback phone number recovery method provides user accounts with the most cyber-attack resistance followed by system-generated recovery codes, a color grid pattern, and graphical passcode. This study surveyed 103 participants about authentication …

Mutex Locking versus Hardware Transactional Memory: An Experimental Evaluation
… discussed, compared, and used in the context of fallback locks for hardware transactions. This thesis provides evidence to the effect that fine-grained locking is not critical for program performance and that in many cases global locking and hardware transactions can provide nearly equivalent …

Design and theoretical analysis of advanced power based positioning in RF system
… based localization schemes can be a fallback solution for robust navigation. For the indoor/outdoor transition scenario, we propose hypothesis test based fusion method to integrate multi-modal localization sensors. In the first paper, a ubiquitous tracking using motion and location …

An Examination Of The Persistence Of Kindling, A Model For Neural Plasticity
… but there was also a consistent degree of fallback seen when comparing the kindling manifestations just before the interval with those exhibited on the first rekindling session. The retention of the kindling effect was not dependent on the animal attaining a fully generalized convulsion, …

Uncertainty-aware fusion of foundation and task-specific models for cardiac MRI segmentation
… Theory (DST) with an entropy-guided fallback mechanism to perform voxel-wise fusion of calibrated probability maps. DST fusion is applied in regions of agreement, while high-conflict regions are handled by selecting predictions from the model with lower uncertainty. Experiments on …

Architectural and compiler support for strongly atomic transactional memory
… of short and small transactions, while allowing fallback to software for large or complicated transactions. I present UTM, a hardware transactional memory system allowing unbounded virtualizable transactions, and show how a hybrid system can be obtained.

WhatWhen2Ask: Cost-Aware LLM Querying for Autonomous Robots in Uncertain Environments
… selective hint filtering, and hierarchical fallback each contribute meaningfully to performance. These results suggest that principled, confidence-aware LLM querying can enhance decision-making in uncertain environments, offering a step toward more efficient and cost-aware language-augmented …

Is cue-based memory retrieval 'good-enough'?: Agreement, comprehension, and implicit prosody in native and bilingual speakers of English
… task allows, and may be required to rely on this fallback route when task demand is high. In the proposed GC model, cue-based memory retrieval (CBMR) is the instantiation of the complete syntactic route for agreement and long-distance dependencies in particular (Lewis & Vasishth, 2005; Wagers, …

Probabilistic machine learning algorithms for molecule discovery
… to large datasets. Finally, retro-fallback (chapter 6) uses a novel probabilistic formulation of the retrosynthesis problem to estimate whether a molecule can be synthesized, and thereby determine whether it should be considered by Bayesian optimisation. Together, these algorithms …

A robust pathfinding algorithm using chemical composition
… Since this method uses chemical composition as a fallback measure, it can be used in the absence of explicit RPAIR information, thus allowing the identification of putative paths not possible via methods using the RPAIR database alone.
