Autapses enhance bursting and coincidence detection in neocortical pyramidal cells

open access: yesNature Communications, 2018
Autapses are synaptic contacts of a neuron’s axon onto its own dendrite and soma. In the neocortex, self-inhibiting autapses in GABAergic interneurons are abundant in number and play critical roles in regulating spike precision and network activity. Here

Phaseless Radar Coincidence Imaging with a MIMO SAR Platform

open access: yesRemote Sensing, 2019
The correlation-based synthetic aperture radar imaging technique, termed radar coincidence imaging, is extended to a fully multistatic multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) configuration.

Background Light Rejection in SPAD-Based LiDAR Sensors by Adaptive Photon Coincidence Detection

open access: yesItalian National Conference on Sensors, 2018
Light detection and ranging (LiDAR) systems based on silicon single-photon avalanche diodes (SPAD) offer several advantages, like the fabrication of system-on-chips with a co-integrated detector and dedicated electronics, as well as low cost and high ...

Electrical Synapses Enhance and Accelerate Interneuron Recruitment in Response to Coincident and Sequential Excitation

open access: yesFrontiers in Cellular Neuroscience, 2018
Electrical synapses are ubiquitous in interneuron networks. They form intercellular pathways, allowing electrical currents to leak between coupled interneurons.

The Large Number Coincidence, The Cosmic Coincidence and the Critical Acceleration [PDF]

open access: yesProc.Roy.Soc.Lond.A462:3657-3661,2006, 2005
The coincidence problem among the pure numbers of order near 10^{40} is resolved with the Raychaudhuri and Friedmann-Robertson-Lemaitre-Walker equations and a trivial relationship involving the fine structure constant. The fact that the large number coincidence occurs only in the same epoch in which other coincidences among cosmic parameters occur ...

Complete rectal prolapse presenting with colorectal cancer

open access: yesInnovative Surgical Sciences, 2023
Rectal prolapse is defined as prolapse of all layers of rectal wallout of the anal sphincter. The aim was to (i) describe the extremely rare combination of a rectal prolapse with colon cancer in an older female patient, (ii) comment on management ...

A coincidence detection system based on real-time software [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2016
Conventional real-time coincidence systems use electronic circuitry to detect coincident pulses (hardware coincidence). In this work, a new concept of coincidence system based on real-time software (software coincidence) is presented.

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

open access: yesMolecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...
