Spontaneous Generation of Infectious Prion Disease in Transgenic Mice [PDF]

open access: yesEmerging Infectious Diseases, 2013
We generated transgenic mice expressing bovine cellular prion protein (PrPC) with a leucine substitution at codon 113 (113L). This protein is homologous to human protein with mutation 102L, and its genetic link with Gerstmann–Sträussler–Scheinker ...

Optimal photon generation from spontaneous Raman processes in cold atoms [PDF]

open access: yesNew Journal of Physics, 2018
Spontaneous Raman processes in cold atoms have been widely used in the past decade for generating single photons. Here, we present a method to optimise their efficiencies for given atomic coherences and optical depths.

Può un uomo generarsi nell’utero di una capra o di una cagna? Una quaestio di Urbano da Bologna nel commento alla Physica di Averroè [PDF]

open access: yesNoctua, 2023
In Latin Europe, the controversy over spontaneous generation of perfect animals – namely those whose breeding occurs through sexual reproduction – is received in different ways, varying from positions very close to Avicenna’s, as in the case of Pietro ...

Self-Supervised Spontaneous Latent-Based Facial Expression Sequence Generation

open access: yesIEEE Open Journal of Signal Processing, 2023
In this article, we investigate the spontaneity issue in facial expression sequence generation. Current leading methods in the field are commonly reliant on manually adjusted conditional variables to direct the model to generate a specific class of ...

Różne Oblicza Sławnego Odkrywcy Pamięci Ludwika Pasteura w 200. Rocznicę Urodzin

open access: yesPostępy Mikrobiologii, 2022
Ludwik Pasteur uznawany jest za jednego z największych naukowców. A jednak nawet na pomnikowej postaci Pasteura dostrzegane są rysy. Jego charakter i pewne działania są przedmiotem krytyki lub co najmniej kontrowersji.

Spontaneous prediction error generation in schizophrenia. [PDF]

open access: yesPLoS ONE, 2012
Goal-directed human behavior is enabled by hierarchically-organized neural systems that process executive commands associated with higher brain areas in response to sensory and motor signals from lower brain areas.

Reconsidering Read and Spontaneous Speech: Causal Perspectives on the Generation of Training Data for Automatic Speech Recognition

open access: yesInformation, 2023
Superficially, read and spontaneous speech—the two main kinds of training data for automatic speech recognition—appear as complementary, but are equal: pairs of texts and acoustic signals. Yet, spontaneous speech is typically harder for recognition. This

H1-antihistamine up-dosing in chronic spontaneous urticaria: patients' perspective of effectiveness and side effects--a retrospective survey study. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: The guidelines recommend that first line treatment of chronic spontaneous urticaria should be second generation non-sedating H(1)-antihistamines with a positive recommendation against the use of old sedating first generation antihistamines ...
