Green upgrading of SPring‐8 to produce stable, ultrabrilliant hard X‐ray beams

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 6, Page 1420-1437, November 2024.
This paper presents an overview of a major upgrade project of SPring‐8, SPring‐8‐II, including ultra‐low‐emittance accelerator design and expected performances. The paper also discusses our approach towards the next generation light source aiming at the reduction of power consumptions.SPring‐8‐II is a major upgrade project of SPring‐8 that was ...

Turbo EP-based Equalization: a Filter-Type Implementation [PDF]

open access: yesarXiv, 2017
This manuscript has been submitted to Transactions on Communications on September 7, 2017; revised on January 10, 2018 and March 27, 2018; and accepted on April 25, 2018 We propose a novel filter-type equalizer to improve the solution of the linear minimum-mean squared-error (LMMSE) turbo equalizer, with computational complexity constrained to be ...

Re‐thinking youth work as initial mental health support for young people

open access: yesChildren &Society, Volume 38, Issue 6, Page 1920-1942, November 2024.
Abstract Youth work is a practice that supports young people and bolsters mental health and well‐being. In the aftermath of the Covid‐19 pandemic, young people in the UK have experienced rising levels of mental distress. However, in the broader youth policy field, youth work is rarely acknowledged as a mental health support.

Joint Multilevel Turbo Equalization and Continuous Phase Frequency Shift Keying

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
A novel type of turbo coded modulation scheme, called multilevel turbo coded-continuous phase frequency shift keying (MLTC-CPFSK), is designed to improve the overall bit error rate (BER) and bandwidth efficiency. Then, this scheme is combined with a new

Optimization of LDPC Codes over the Underwater Acoustic Channel

open access: yesInternational Journal of Distributed Sensor Networks, 2016
To combat severe intersymbol interference incurred by multipath propagation of sound waves in the underwater acoustic environment, we introduce an iterative equalization and decoding scheme by iteratively exchanging soft information between a low-density

Turbo-Like Beamforming Based on Tabu Search Algorithm for Millimeter-Wave Massive MIMO Systems [PDF]

open access: yesarXiv, 2015
For millimeter-wave (mmWave) massive MIMO systems, the codebook-based analog beamforming (including transmit precoding and receive combining) is usually used to compensate the severe attenuation of mmWave signals. However, conventional beamforming schemes involve complicated search among pre-defined codebooks to find out the optimal pair of analog ...

A double EP-based proposal for turbo equalization [PDF]

open access: yes, 2019
This letter deals with the application of the expectation propagation (EP) algorithm to turbo equalization. The EP has been successfully applied to obtain either a better approximation at the output of the equalizer or at the output of the channel decoder to better initialize the Gaussian prior used by the equalizer.

Dorsomedial striatal AMPA receptor antagonism increases alcohol binge drinking in selectively bred crossed high alcohol preferring mice

open access: yesEuropean Journal of Neuroscience, Volume 60, Issue 9, Page 6300-6311, November 2024.
AMPA receptor antagonism in the dorsomedial striatum of selectively bred high alcohol preferring mice causes an increase in binge alcohol drinking. AMPA receptor antagonism in the dorsolateral striatum of selectively bred high alcohol preferring mice does not alter binge alcohol drinking.

Digoxin and exercise effects on skeletal muscle Na+,K+‐ATPase isoform gene expression in healthy humans

open access: yesExperimental Physiology, Volume 109, Issue 11, Page 1909-1921, 1 November 2024.
Abstract In muscle, digoxin inhibits Na+,K+‐ATPase (NKA) whereas acute exercise can increase NKA gene expression, consistent with training‐induced increased NKA content. We investigated whether oral digoxin increased NKA isoform mRNA expression (qPCR) in muscle at rest, during and post‐exercise in 10 healthy adults, who received digoxin (DIG, 0.25 mg ...

Interference Coordination for E-MBMS Transmissions in LTE-Advanced

open access: yesInternational Journal of Digital Multimedia Broadcasting, 2010
Interference coordination methods for Evolved-Multimedia Broadcast/Multicast Service (E-MBMS) in Long-Term Evolution Advanced (LTE-A) are presented. In addition, we consider signal space diversity based on Rotation Matrices (RM) known to provide good ...
