Dynamic Updating of Cognitive Maps via Traces of Experience in the Subiculum. [PDF]

open access: yesHippocampus
ABSTRACT In the classical view of hippocampal function, the subiculum is assigned the role of the output layer. In spatial paradigms, some subiculum neurons manifest as so‐called boundary vector cells (BVCs), firing in response to boundaries at specific allocentric directions and distances.

Hippocampal-Prelimbic Coupling During Context-Dependent Extinction Retrieval in Rats. [PDF]

open access: yesHippocampus
ABSTRACT After fear conditioning, repeated presentation of the conditioned stimulus (CS) alone produces a context‐dependent extinction of learned fear. The hippocampus has a critical role in this process, but the mechanism by which contextual information encoded by the hippocampus leads to fear suppression is unknown.

FORMATION OF A SIGNAL WITH HARTLEY AMPLITUDE-PHASE MODULATION AS THE SUM OF TWO SIGNALS WITH HARTLEY AMPLITUDE MODULATION

open access: yesOdes’kyi Politechnichnyi Universytet Pratsi
The paper presents the results of the research, which outcome in the development of a theoretical justification for a new type of modulation – Hartley amplitude-phase modulation. This type of modulation has an additional carrier that is orthogonal to the known amplitude-phase modulation. Moreover, the in-phase and quadrature

Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]

open access: yes, 2003
A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and

The Effect of EMI Generated from Spread-Spectrum-Modulated SiC-Based Buck Converter on the G3-PLC Channel [PDF]

open access: yes, 2021
Power line communication (PLC) is increasingly emerging as an important communication technology for the smart-grid environment. As PLC systems use the existing infrastructure, they are always exposed to conducted electromagnetic interference (EMI) from ...

Nitric oxide-mediated modulation of the murine locomotor network [PDF]

open access: yes, 2014
CD was supported by a BBSRC studentshipSpinal motor control networks are regulated by neuromodulatory systems to allow adaptability of movements. The present study aimed to elucidate the role of nitric oxide (NO) in the modulation of mammalian spinal ...

MIMO free-space optical communication employing subcarrier intensity modulation in atmospheric turbulence channels [PDF]

open access: yes, 2009
In this paper, we analyse the error performance of transmitter/receiver array free-space optical (FSO) communication system employing binary phase shift keying (BPSK) subcarrier intensity modulation (SIM) in clear but turbulent atmospheric channel ...

Bispectrum Analysis of Motor Current Signals for Fault Diagnosis of Reciprocating Compressors [PDF]

open access: yes, 2009
The induction motor is the most common driver in industry and has been previously proposed as a means of inferring the condition of an entire equipment train, predominantly through the measurement and processing of power supply parameters.

Boundary vector cells in the subiculum of the hippocampal formation [PDF]

open access: yes, 2009
Stretching a familiar rectangular environment along one axis results in a stretching of place cell (PC) firing fields (“place fields”) along the same axis (O’Keefe and Burgess, 1996).

Spectrally Augmented Hartley Transform Precoded Asymmetrically Clipped Optical OFDM for VLC [PDF]

open access: yes, 2018
International audienceIn this letter, layered discrete Hartley transform (DHT)-spread asymmetrically clipped optical-orthogonal frequency division multiplexing (LDHTS-ACO-OFDM) is presented; it uses DHT for multiplexing/demultiplexing and pulse-amplitude
