Ultra‐high‐density mapping to guide effective His‐bundle pacing
Clinical Case Reports, 2021 Permanent His bundle pacing is a physiological alternative to right ventricular pacing, resulting in a lower probability of pacing‐induced cardiomyopathy and left ventricular ejection fraction deterioration. The combined use of UHD mapping systems allows

His bundle activates faster than ventricular myocardium during prolonged ventricular fibrillation. [PDF]
PLoS ONE, 2014 The Purkinje fiber system has recently been implicated as an important driver of the rapid activation rate during long duration ventricular fibrillation (VF>2 minutes).

A topological definition of the Maslov bundle [PDF]
, 2006 We give a definition of the Maslov fibre bundle for a lagrangian submanifold of the cotangent bundle of a smooth manofold. This definition generelizes the definition given, in homotopic terms, by Arnol'd for lagrangian submanifolds of the cotangent ...

A Simple and Approximately Optimal Mechanism for an Additive Buyer
, 2020 We consider a monopolist seller with $n$ heterogeneous items, facing a single buyer. The buyer has a value for each item drawn independently according to (non-identical) distributions, and her value for a set of items is additive.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

FIRST EXPERIENCE OF DIRECT CONSTANT HIS BUNDLE PACING
Медицинский вестник Юга России, 2016 Objective: to study electrophysiological parameters and clinical results of direct constant His bundle pacing (HBP). Materials and methods: we examined 36 patients, divided into 2 equal groups (of 18 patients) according to the type of pacing.
