Program analysis of temporal memory mismanagement
… benefits obtained from flexible low-level memory access and management sacrifice language-level support for memory safety and garbage collection. Memory-related programming mistakes are introduced as a result, rendering C/C++ programs prone to memory errors. A common category of programming …

An application of Hierarchical Temporal Memory (HTM)
… based on that theory - namely Hierarchical Temporal Memory (HTM). Current opinion raises question marks as to whether this theory is sound, feasible, coherent, logical and correct. This thesis aims to, if not answer some of those questions, at least get closer to understanding the brain and …

Using Space to Remember Time
… personally relevant events. In early childhood, memory for the temporal order of events tends to be weaker than memory for the location of those events. A potential solution to this challenge is to engage the mental timeline, a linear projection of time onto space. Although adults and older …

Memory for Emotional Images : Recognition and Temporal Contexts
… visual presentation paradigm and recognition and temporal memory item-discrimination tasks were used. Binding theory predicts no differences between negative and neutral images for recognition and temporal memory. Results were consistent with the assumptions of binding theory and no significant …

Asynchronous hardware-enforced memory safety
Memory corruption attacks, such as buffer overflow attacks, have been threatening software security for more than three decades. Despite tremendous efforts by developers and researchers to prevent programs written in memory-unsafe language (e.g., C/C++) from memory errors (the root cause of memory …

Decoding the emotional modulation of memory encoding: a multivariate fmri study of arousal and valence
… to the neural patterns supporting memory encoding are not fully understood. We leveraged multivariate pattern analysis (MVPA) to dissociate these influences. We analysed fMRI data from a large cohort of participants during an emotional picture encoding task with a subsequent free …

TRUSTED RUNTIME ENVIRONMENTS FOR EMBEDDED SYSTEMS: FROM MEMORY PROTECTION TO SECURE VIRTUALIZATION
… constrained by limited computational and memory resources. This thesis addresses these challenges by proposing lightweight, scalable mechanisms for runtime memory protection and secure execution, with an emphasis on minimizing device overhead through remote verification. To strengthen …

Convicted by memory: Automatically recovering spatial-temporal evidence from memory images
<p>Memory forensics can reveal “up to the minute” evidence of a device’s usage, often without requiring a suspect’s password to unlock the device, and it is oblivious to any persistent storage encryption schemes, e.g., whole disk encryption. Prior to my work, researchers and investigators alike …

Designing Practical Software Bug Detectors Using Commodity Hardware and Common Programming Patterns
… of three approaches using data race bugs, memory safety bugs, and permission check bugs, respectively. First, we leverage the commodity hardware transactional memory (HTM) selectively to use the dynamic data race detector only if necessary, thereby reducing the overhead from 11.68x to …

Towards Real-World Quantum Machine Learning
… circuit as the reservoir while injecting temporal memory via an explicit feedback loop. The register is recycled across time, so quantum resources remain constant, no quantum parameters are trained, and only a lightweight classical readout is fitted. Experiments on chaotic time series …

BOOLEAN AND BRAIN-INSPIRED COMPUTING USING SPIN-TRANSFER TORQUE DEVICES
… devices can be explored in compact, low power memory and logic design. In order to truly leverage STT devices based computing, researchers require a re-think of circuit, architecture, and computing model, since the STT devices are unlikely to be drop-in replacements for CMOS. The potential of …

Capability Memory Protection for Embedded Systems
… embedded systems, to address existing memory safety and task isolation problems as well as providing new means to design a secure and scalable real-time system. In addition, this dissertation looks into how practical and high-performance temporal memory safety can be achieved under a …

Toward transient-execution attack mitigations on CHERI
… capabilities that help to tackle spatial and temporal memory safety issues. However, the CHERI ISA has not been designed with transient-execution vulnerabilities in mind. In order to satisfy performance requirements, CHERI implementations employ out-of-order and speculative execution …

Temporally distinct impairments in cognitive function following a sensitizing regimen of methamphetamine
… impairments in executive function, learning, memory, and impulsivity. These impairments, specifically those that engage the prefrontal cortex (PFC) or hippocampus (HC), may persist or recover based on the duration of abstinence. In rodents, repeated intermittent injections of MA yield …

The Role of the Posterior Parietal Cortex in Subjective and Objective Episodic Memory Recollection
… of this project was to compare the Attention to Memory (AtoM) and the Episodic Buffer (EB) Models. The AtoM model proposes that the ventral parietal cortex (VPC) and dorsal parietal cortex (DPC) are responsive to bottom-up and top- down attention to memory, respectively, (Cabeza, 2008; Cabeza et …

A Purkinje cell Timing Mechanism. On the Physical Basis of a Temporal Duration Memory.
… with adaptively timed pauses without such a temporally patterned input. Training Purkinje cells with direct stimulation of their presynaptic fibers, and pharmacological blocking of interneurons shows that the timing mechanism is intrinsic to the cell itself and not an emergent property of the …
