Comparative study of an antioxidant defense mechanism in genotypes of eastern white pine which show differential foliar characteristics
Approximately 10-15% of field-grown eastern white pine (Pinus strobus L.) within a nursery plantation expressed foliar characteristics similar to that induced by oxidant pollution. Sensitive genotypes (based on foliar characteristics), had a 50% reduction in needle growth, severe needle tip burn, …

PACTIGHT: Tightly Seal Sensitive Pointers with Pointer Authentication
… importance of having an effective and efficient defense mechanism for ARM. ARM has released Pointer Authentication, a new hardware security feature that is intended to ensure pointer integrity with cryptographic primitives. Recently, it has been found to be vulnerable. In this thesis, we utilize …

Implementation of a Testbed with SDN-enabled Communication Networks to Experiment on Physical Function Virtualization that Disrupts Reconnaissance of Cyber-Physical Infrastructures
… after extensive reconnaissance. One intuitive defense idea is to disrupt the reconnaissance or to increase the cost of such reconnaissance.To achieve this, we propose physical function virtualization (PFV), in which we introduce a certain amount of lightweight virtual nodes. The virtual nodes …

Distributing network identity to mitigate denial-of-service attacks
… carried out by Draper Laboratory to provide a defense mechanism against distributed denial of service (DDoS) attacks to both prevent DDoS attacks and mitigate their effects. This Masters project looks at the CONTRA system and assesses its effectiveness. The goal of this project is to explore …

Potential applications of the natural design of internal explosion chambers in the bombardier beetle (Carabidae, Brachinus)
… (Carabidae, Brachinus) has a unique form of defense mechanism which involves the explosive mixing of hydroquinones and hydrogen peroxide in its internal explosion chambers and using the resultant high pressure to spray out a heated corrosive fluid containing p-benzoquinones in a controlled …

An effective network flow prioritization approach in DDoS scenarios
… To mitigate DDoS attacks, it is crucial for a defense mechanism to have a policy that can discriminate legitimate network flows from the malicious ones. Such a fairness policy will help prioritizing the legitimate flows and prevent the system from DDoS attacks. In this thesis, we present and …

Elucidating the Structural and Dynamical Properties of the Intrinsically Disordered Protein Nrf2 Using Molecular Dynamics Simulations
… the antioxidant response pathway, a primary defense mechanism against disproportionate levels of oxidants in the cell, via the upregulation of cytoprotective genes. Notably, aberrant activation of Nrf2 in cancer cells increases their resistance to chemotherapy, rendering the treatment …

Investigating the Relationship Between Defense Mechanisms and the Therapeutic Alliance in Dialectical Behaviour Therapy for Borderline Personality Disorder
Defenses play an important role in psychotherapy, as clients' overall defensive functioning (ODF) predicts treatment outcomes. Defensive functioning may influence the relationship between the therapeutic alliance and outcome; however, findings are mixed. This study examined the relationship between …

The Endowment Effect: A Self-Enhancement Perspective
… and sellers as a part of their automatic defense mechanism respond to this self-threat by enhancing the value of the self-associated object. Three studies test the above hypothesis and provide support to the proposed model.</p>

Role of SABP2 in Systemic Acquired Resistance Induced by Acibenzolar-S-Methyl in Plants.
<p>Plants have evolved an efficient mechanism to defend themselves against pathogens. Many biotic and abiotic agents have been shown to induce defense mechanism in plants. Acibenzolar-S-Methyl (ASM) is a commercially available chemical inducer of local and systemic resistance (SAR) response in …

How is a Woman Like a Watermelon?: Advocating a Psychological and Comparative Examination of Brautigan's Novels
… personal detachment, the use of projection as a defense mechanism, and the psychological associative value of words, images and memories. An inclusive and comparative study that foregrounds these psychological elements will ultimately allow for a more complete and subtle analysis of Brautigan's …

Practical Mitigations Against Memory Corruption and Transient Execution Attacks
… for more than 30 years, and over the years many defenses have been proposed. In addition to that, a new class of attacks, Spectre, has emerged that abuse speculative execution to leak secrets and sensitive data through micro-architectural side channels. Many defenses have been proposed to …

Asthma: Cytokine-Induced Over-Expression of Matrix Metalloproteases Compromises Airway Epithelium Tight Junctions and a Clinical Case Study
… epithelium's ability to act as a primary immune defense mechanism. The chronic characterization of asthma results because of an ineffective epithelial repair mechanism which prevents full recovery of the affected airway tissues thus allowing for further aggravation by environmental pathogens. …

Extraction of Leucocidin From Staphylococci and Its Practical Application in the Diagnosis of Septicemia
… (l) in 1895 the importance of the cellular defense mechanism has been recognized. The great number of investigations on the various aspects of the subject of phagocytosis that appear in the worlds literature serve as convincing evidence for recognition of the necessity for a thorough …

Recognizing change : a set of short studies in pattern
… a condition which can be both a useful defense mechanism and a paralyzing affliction. Faced with increasing technological change, contemporary culture has exhibited distinct patterns of resistance, patterns that describe a cultural condition of Narcissism. This project examines the …

Host-Defense Function of Anuclear Polymorphonuclear Neutrophil in Lung Injury
… inflammatory lung injury. Unlike PMN, the host defense function of PMNcyto waned over time, first observed by in vivo imaging loss in velocity. Upon further investigation using seahorse assay, we observed a loss in mitochondrial functions. Mitochondrial transplantation restored the host defense …

Physics-based Security Analysis of Controller Area Network Protocols
… we develop software and hardware-based defense mechanisms that can detect attacks by exploiting timing, voltage, and motion information, where the hardware-based defense mechanism can also mitigate these attacks. We implement the attacks and demonstrate that the proposed defense …
