Resistive switching in electrochemical metallization memory cells
New memory technologies must be easily integrable into standard semiconductor processes and allow for a high memory density. The aim is the fabrication of non-volatile memory devices with a low power consumption. The devices should be read out non-destructively, and have a high endurance and high …

INTRA-TUMORAL INFILTRATION OF GZMKHIGH CD8+ T EFFECTOR MEMORY CELLS IS ASSOCIATED WITH POOR CLINICAL OUTCOME IN NON-METASTATIC COLORECTAL CANCER.
… interplay between neutrophils and CD8+ T cells that impacts on tumor immune escape and relapse. Specifically, we showed that tumor infiltrating neutrophils expressing high levels of CD15 interact with CD8+ T effector memory cells skewing them to produce GZMK, associated with tumor …

Fault-Tolerant Distributed Algorithms for Agreement and Election
… part, we characterize completely the shared-memory requirements for achieving agreement in an asynchronous system of fail-stop processes that die undetectably. There is no agreement protocol that uses only read and write operations, even if at most one process dies. This result implies the …

Resistive switching in Cu:TCNQ thin films
… a growing interest in alternative non-volatile memory technology concepts for massive data storage, which have the potential to eventually replace Flash in future CMOS generations. Resistive switching materials, which can be incorporated in simple metal-isolator-metal (MIM) structure, are …

Modulation of CD8+ T Cell Function by Beta2-Adrenergic Receptor Signaling
… has demonstrated that various subsets of CD8+ T cells have differential expression of the ADRB2 transcript. The role of ADRB2 signaling on the differentiation and acute effector functions of CD8+ T cells remains poorly understood. More importantly, its effect on CD8+ T cell memory development …

In vitro generation and programming of human CD8+ memory T cells
… the generation of persistent and functional memory CD8+ T cells. The integration of a multitude of signals during naïve cell activation plays an important role in the programming of CD8+ T cells responses. However, knowledge of the regulation of naïve cell programming in humans is limited. …

Screening for genes involved in CD8⁺ T cell cytotoxicity and characterisation of a super-killer
Cytotoxic T Lymphocytes (CTL) are cells of the adaptive immune system that are responsible for the elimination of virally infected, tumorigenic or damaged cells through mechanisms that induce target cell lysis. The aim of this project was to identify genes that can impact CTL lytic capacity, using …

Development of a novel co-vaccination approach for pneumococcal and influenza infections
… vaccine efficacy was shown to be reliant on B cells and IL-17 responses. Importantly, immunisation promoted IL-17 production by γδ T cells, as opposed to conventional Th17 cells commonly reported with other pneumococcal whole cell vaccines. Moreover, this study also illustrated that the …

Flash Memory For Ubiquitous Hardware Security Functions
We demonstrate that unmodified commercial Flash memory can provide three important security functions: true random number generation, digital fingerprinting and information hiding. Use of random telegraph noise (a type of quantum noise source in highly scaled Flash memory cells) enables high …

Defining mRNA-generated T cell memory in respiratory viral infection
T cell immune memory provides protective effector mechanisms to restrict pathogen growth upon secondary infection, although the ability of T cells generated by novel mRNA-LNP vaccines to restrict viral infection in currently unknown. To address this, we studied antigen specific T cell memory …

MODULATION OF THE B-CELL REPERTOIRE IN RHEUMATOID ARTHRITIS BY TRANSIENT B-CELL DEPLETION
Although the role of B-cells in autoimmunity is not completely understood, their importance in the pathogenesis of autoimmune diseases has been more appreciated in the past few years. It is now well known that they have roles in addition to (auto) antibody production and are involved by different …
