With the proliferation of Audio Language Model (ALM) based deepfake audio, there is an urgent need for generalized detection methods. ALM-based audio currently exhibits widespread, high deception, and type versatility, posing a significant challenge to current (ADD) models trained solely on vocoded data. To effectively detect we focus mechanism generation method, conversion from neural codec waveform. We initially constructed Codecfake dataset, open-source, large-scale collection comprising...

Purpose. The present study evaluates the preliminary effectiveness of a parent-implemented support program to enhance language outcomes in Chinese-learning preschoolers with confirmed diagnosis or at elevated likelihood autism, lifelong neurodevelopmental condition. is delivered entirely online option group format. Because cross-cultural differences adult learning and parent-child interaction because parent coaching programs for autism that are only emerging, specific evaluate Chinese...

The chemical investigation of the EtOAc extract from solid rice medium cultured with a sponge-associated fungus Penicillium sp. SCSIO41033 led to isolation two quinolones including new one, penicinolone (1), three xanthone derivatives (3-5), and four anthraquinones (6-9). Their structures were determined by comprehensive analysis 1H 13C NMR, COSY, HSQC, HMBC spectroscopic, HRESIMS mass spectrometric data. bioactive assays revealed that compounds 1 2 showed no antimicrobial activities against...

The China Spallation Neutron Source (CSNS) accelerator consists of an 80 MeV ${H}^{\ensuremath{-}}$ Linac and a 1.6-GeV rapid cycling synchrotron (RCS). painting scheme is one the most important factors for control low beam loss at high power. In injection CSNS/RCS, position scanning used in both horizontal vertical planes, anticorrelated design scheme. By using painting, power has successfully reached 50 kW. However, some problems have been found higher commissioning, instance, too large...

<b><i>Introduction:</i></b> Caregiver-implemented language programmes are effective for alleviating early difficulties. This study examined the efficacy of a self-directed video-based caregiver-implement programme in Chinese families. <b><i>Method:</i></b> consisted two stages. In stage 1, 31 caregiver-child dyads (typically developing children) completed training (group 1) form six modules. 2, 28 (children with difficulties) receiving active...

Temperature is a crucial parameter in the spin-exchange optical pumping (SEOP) process of noble gas (3He), but hard to measure due its confinement nature. In this paper, we conduct research upon temperature and flow distribution within sealed SEOP cell through computational fluid dynamics simulation. The simulation result shows that external heat exchange initial heating becomes cooling presence high laser power absorbed by alkali metal. from would also cause reach much higher than oven,...

Abstract As a bioinspired sensor with high temporal resolution, the spiking cameras have enormous potential in real applications, yet it remains largely unknown how to improve their performance. In this study, we showed that dynamic range of neuronal networks could be maximized jointly by critical dynamics resulting from balanced excitatory and inhibitory synaptic currents heterogeneity resting potentials neurons networks. We then built camera demonstrate its performance, characterized peak...
