All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Stimulation of Lymphocytes by Spermatozoa‐Stimulated Cells*

American Journal of Reproductive Immunology, 1982
ABSTRACT: The mechanism of spermatozoalymphocyte interaction was studied using spermatozoa and lymphocytes obtained from 11 healthy individuals and from 2 patients with spermatocoele. The lymphocytes activated by spermatozoa in 3‐day cultures were used as inducers of fresh, unstimulated autologous or allogeneic lymphocytes.

Stimulation of Cells by Antibody

Science, 1973
Tumor cell lines exposed to immunoglobulins specific for cell surface antigens developed increased cellular incorporation of [ 125 I]iododeoxyuridine and [ 3 H]thymidine (up to 200-fold increases over cells treated with normal rabbit immunoglobulins). Antibody-stimulated cells multiplied more

B-cell stimulation

Current Opinion in Immunology, 1995
Recent studies have identified CD40 ligand (CD40L) as the critical membrane-expressed molecule responsible for T cell dependent B-cell activation. CD40L co-operates with various cytokines to induce B-cell activation, proliferation, and immunoglobulin isotype switching.

Development of a miniaturized stimulation device for electrical stimulation of cells [PDF]

Journal of Biological Engineering, 2015
Directing cell behaviour using controllable, on-demand non-biochemical methods, such as electrical stimulation is an attractive area of research. While there exists much potential in exploring different modes of electrical stimulation and investigating a wider range of cellular phenomena that can arise from electrical stimulation, progress in this ...

Stimulation of haemopoietic stem cell proliferation: Characteristics of the stimulator-producing cells

Leukemia Research, 1982
Media conditioned by regenerating murine bone marrow cells contain a stimulator of haemopoietic stem cell proliferation. Fractionated cell populations have been examined for production of this stimulatory activity in order to characterize its cellular source.

Stimulation of Spheroidal Cells - The Role of Cell Shape

IEEE Transactions on Biomedical Engineering, 1976
The behavior of spheroidal cells in an applied uniform field is examined in order to gain insight into the role of cell shape in the electrical activity of biological cells. The responses of cells having different eccentricities but the same height in the direction of stimulation are compared.

Contact stimulation of cell migration

Journal of Cell Science, 1992
ABSTRACT Mass migrations of dense cell populations occur periodically during embryonic development. It is known that extracellular matrices, through which the cells migrate, facilitate locomotion. However, this does not explain how cells, such as neural crest, can migrate as a dense cohort of cells in essentially continuous contact with ...
