Characterizing Medial Temporal Lobe Neurodegeneration Due To Tau Pathology In Alzheimer's Disease Using Postmortem Imaging
… (NFT) pathology in the medial temporal lobe (MTL) is closely linked to neurodegeneration, and is the early pathological change associated with Alzheimer’s Disease (AD). Using in vivo structural magnetic resonance image (MRI) analysis, volumetric change in the MTL caused by neurodegeneration …

Feature Extraction Workflows for Urban Mobile-Terrestrial LiDAR Data
Mobile Terrestrial LiDAR (MTL) is an active remote sensing technology that uses laser-based ranging and global positioning systems (GPS) to record 3D point location measurements on surfaces within and near transportation corridors, such as along a railroad track or a street. This thesis examines …

Beyond Episodic Memory: Medial Temporal Lobe Contributions to Problem-solving and Semantic Fluency Tasks
… supported by the medial temporal lobes (MTL) to two goal-oriented non-episodic tasks, problem solving and semantic retrieval (verbal fluency). The reported experiments provide evidence for the hypothesis that MTL-based episodic processes are robustly involved in completing non-episodic …

Novel Methodologies and Measurement Software for Transistor Amplifier Synthesis in Planar Coupled -Transmission Lines
… aspects of multiconductor transmission line (MTL) theory, including longitudinal dependencies of immittance functions. We next describe a frequency domain normal mode parameter extraction method for a symmetric, uniform, MTL section. This is applied to coupled microstrip and coplanar lines for …

Content representation in the human medial temporal lobe
… well-established that the medial temporal lobe (MTL) is crucial to both processes, but the MTL is not a single homogeneous region. In fact, it is composed of several anatomically distinct subregions including hippocampus, perirhinal cortex (PRC) and parahippocampal cortex (PHC). However, the …

Performance Enhancement of Unified Recommendation and Knowledge Graph Completion Learning by Relation Rotation
Advances in multi-task learning (MTL) models have improved the performance and explainability of recommender systems (RS) by jointly learning the recommendation and knowledge graph completion (KGC) tasks. Recent studies have established that considering the incomplete nature of knowledge graphs …

Medial temporal lobe and prefrontal cortex contributions to memory expressed on short timescales
… in the moment. The medial temporal lobe (MTL) is critical for human memory. Its role in memory at long delays is well-established, while its contribution to memory at short delays had not been appreciated until recently, when studies specifically targeted the kind of processing it has come …

Medial Temporal Lobe Structures Contribute to on -Line Processing
… These experiments uniquely demonstrate that the MTL is necessary for normal apprehension of even single stimuli when degraded, and for normal discrimination of even very simple representations after a brief delay. Changes were observed in a maintained representation over time in the face of …

Medial Temporal Lobe Does Not Tell The Whole Story: Episodic Memory In ‘atypical’ Variants Of Alzheimer’s Disease
… shrinkage of structures in medial temporal lobe (MTL), including the hippocampus. According to Braak staging, tangles begin in the transentorhinal cortex of the MTL, which then spreads to hippocampal subfields, and later to neocortical areas. Cases that are less recognized by the general public …

Mapping Myocardial Elasticity with Intracardiac Acoustic Radiation Force Impulse Methods
… and spatially. Multiple track location SWEI (MTL-SWEI) is used to show that, in healthy in vivo porcine ventricles, shear wave speeds follow the elasticity changes with contraction and relaxation of the myocardium, varying between 0.9 and 2.2 m/s in diastole and 2.6 and 5.1 m/s in systole. …

ACCURACY IMPROVEMENT OF CABLE HARNESS MODELING & ANALYTICAL MODELING OF MULTI-REFLECTIONS IN HIGH-SPEED SIGNAL CHANNELS
… the hybrid multiconductor transmission-line (MTL) method has been developed, and the generalized MTL (GMTL) method and the multiple scattering (MS) method have been developed to improve the accuracy of the hybrid MTL method. In this research, the convergence issue in the GMTL method near the …

Contributions Of the Human Medial Prefrontal Cortex To Associative Recognition Memory: Evidence From Functional Neuroimaging
… focused their attention on medial temporal lobe (MTL). There is growing acknowledgement however, from the cognitive neuroscience of memory literature, that regions outside the MTL can support episodic memory processes. The medial prefrontal cortex is one such region garnering increasing interest …

Utilizing Multitask Transfer Learning for Sonographic Rheumatoid Arthritis Synovitis Grading
… research proposes a Multitask Transfer Learning (MTL) framework for sonographic RA synovitis grading of Ultrasound (US) images in Brightness mode (B-Mode) and Power Doppler mode.</p> <p>In the medical community, the lack of reliability of scoring these images has been an issue and reason for …

An electrophysiological basis for human memory
… coupled between the medial temporal lobe (MTL) memory system and the temporal association cortex, and this coupling preceded the reinstatement of memory representations from the memory encoding period. Next, we measured single unit spiking activity from anterior temporal lobe in order to …

Investigating the impact of e-cigarettes on lung cells: a combined in vitro and computational study
… under direct-to-lung (DTL) and mouth-to-lung (MTL) vaping regimens. DTL produced higher overall deposition, particularly in distal lung regions, while MTL led to greater deposition in the upper airways. These differences reflected DTL’s higher flow rates and larger puff volumes. Deposited …

Event Typicality and Memory: Investigating How Prior Knowledge and Novelty Modulate Memory for Complex Events
… greater activation in the medial temporal lobes (MTLs) and posterior sensory cortices. During retrieval, however, such differences based on typicality are subtler, with retrieval supported by the MTLs, irrespective of event typicality, at all time points. Notwithstanding these overall neural …

Distinguishing Medial Temporal Lobe and Prefrontal Cortex Contributions to Approach-Avoidance Conflict in Healthy Controls and Generalized Anxiety Disorder: Insights from Functional Magnetic Resonance Imaging and the Hierarchical Drift Diffusion Model
… regions including the medial temporal lobe (MTL), striatum, and prefrontal cortex (PFC). This work, however, is limited in two respects. (1) Human models employing functional Magnetic Resonance Imaging (fMRI) have historically relied on analyses that fail to disentangle how neural activity …

Individuals With Amnesia are not Stuck in Time: Evidence From Risky Decision-Making, Intertemporal Choice, and Scaffolded Narratives
… existing research showing that those with MTL damage have impaired ability to (re)construct rich and detailed narratives of past and future experiences, and I extended this finding for the first time to a lateral dorsal thalamic stroke case (Experiment 1). Despite this impairment in mental …

Theta oscillations, timing and cholinergic modulation in the rodent hippocampal circuit
The medial temporal lobe (MTL) is crucial for episodic and spatial memory, and shows rhythmicity in the local field potential and neuronal spiking. Gamma oscillations (>40Hz) are mediatepd by local circuitry and interact with slower theta oscillations (6-10 Hz). Both oscillation frequencies are …
