Study on reliability technology of contactor relay

Abstract

Text-guided diffusion models catalyze a paradigm shift in audio generation, facilitating the adaptability of source audio to conform to specific textual prompts. Recent advancements introduce inversion techniques, like DDIM inversion, to zero-shot editing, exploiting pre-trained diffusion models for audio modification. Nonetheless, our investigation exposes that DDIM inversion suffers from an accumulation of errors across each diffusion step, undermining its efficacy. And the lack of attention control hinders the fine-grained manipulations of music. To counteract these limitations, we introduce the Disentangled Inversion technique, which is designed to disentangle the diffusion process into triple branches, thereby magnifying their individual capabilities for both precise editing and preservation. Furthermore, we propose the Harmonized Attention Control framework, which unifies the mutual self-attention and cross-attention with an additional Harmonic Branch to achieve the desired composition and structural information in the target music. Collectively, these innovations comprise the Disentangled Inversion Control (DIC) framework, enabling accurate music editing whilst safeguarding structural integrity. To benchmark audio editing efficacy, we introduce ZoME-Bench, a comprehensive music editing benchmark hosting 1,100 samples spread across 10 distinct editing categories, which facilitates both zero-shot and instruction-based music editing tasks. Our method demonstrates unparalleled performance in edit fidelity and essential content preservation, outperforming contemporary state-of-the-art inversion techniques. 34 * Equal contribution † Corresponding Author 3 Audio samples are available at https://MEDIC-Zero.github.io/.

High solid content latex: Preparation methods and application

“…A series of high solid content (70% v/v) butylacrylate/methyl methacrylate/methacrylic acid(BA/MMA/MAA) copolymer emulsions were synthesized by Liu et al [35,36] using semi-continuous emulsion polymerization with consecutive extraction. They studied the effect of the monomer ratio of soft segment (BA) and hard segment (MMA) on the rheological behavior of emulsion.…”

Approved antibacterial drugs in the last 10 years: from the bench to the clinic

“…We highlight here, a novel iridiumcatalyzed N-H insertion reaction to afford the chiral core 3-piperidinone moiety (67). Then, a diastereoselective ketone reduction followed by alcohol activation and displacement with a hydroxyl amine derivative furnished the compound (70) in good overall yield. Triphosgene-mediated urea formation provided the bicyclo[3.2.1] urea (71), which through functional group interconversion, yielded relebactam (64, Figure 13).…”

“…To date, there are not publications from academic labs regarding the synthesis of ozenoxacin, however, several patents covering its preparation are published [68]. One of them employs the Suzuki reaction [69] as the key step transformation in the cross-coupling of two fragments as depicted in Figure 25, the boronic acid (114) and advanced intermediate (115) [70].…”

Numerical Simulation and Optimization of Processing Parameters for Fine-Blanking of FPG

“…Therefore, the precision blanking process is more and more widely adopted in tooth-type components. Specially, internal gears treated by fine extrusion, its inside metal fiber don't have been cut off, which can greatly improve the mechanical strength [2].Improper fine-blanking process parameters may cause excessive die-roll, low smooth-shear surface ratio. Thus, to get reasonable process parameters is the important segment of precision blanking study.…”
