Digital-twin driven alignment control method for marine shafting with air spring vibration isolation system.

Shafting alignment is crucial for marine propulsion systems and may affect the safety and stability of ship operations. Air spring vibration isolation systems (ASVISs) for marine shafting can help control the shafting alignment state by actively adjusting air spring pressures while effectively reducing the mechanical noise. However, how to accurately control the alignment state of marine shafting with air spring vibration isolation system remains a challenge.

Brain space analyses focused on N1m and P1m latency, as well as N1m-to-P1m amplitude.

Exploiting full-duplex opportunities in WLANs via a reinforcement learning-based medium access control protocol.

In-band full-duplex communication has the potential to double the wireless channel capacity. However, how to efficiently transform the full-duplex gain at the physical layer into network throughput improvement is still a challenge, especially in dynamic communication environments. This paper presents a reinforcement learning-based full-duplex (RLFD) medium access control (MAC) protocol for wireless local-area networks (WLANs) with full-duplex access points.

Deterministic quantum state and gate teleportation between distant superconducting chips.

Quantum teleportation is of both fundamental interest and great practical importance in quantum information science. To date, quantum teleportation has been implemented in various physical systems, among which superconducting qubits are of particular practical significance as they emerge as a leading system to realize large-scale quantum computation. Nevertheless, scaling up the number of superconducting qubits on a single chip becomes increasing challenging because of some emergent technical difficulties.

Pt-modified hollow tube-like polyaniline-based NH sensor.

Polyaniline (PANI) has significant applications in room-temperature NH detection due to its unique and reversible doping-dedoping chemical state, stable electrical conductivity and easy and convenient synthesis process. However, pristine PANI still suffers from poor performance in terms of sensitivity, response speed and detection limit. To address issues of low sensitivity and high detection limit, a platinum (Pt)-modified hollow PANI (Pt-PANI) sensor was designed.

Heterologous expression of a highly thermostable L-asparaginase from Thermococcus zilligii in Aspergillus niger for efficient reduction of acrylamide in French fries.

L-asparaginase (L-ASNase) can hydrolyze L-asparagine, a precursor to acrylamide, thereby reducing toxic acrylamide formation in fried foods. Currently, commercial L-ASNases are primarily produced by wild-type (WT) filamentous fungi; however, these enzymes often exhibit rapid activity loss during high-temperature processing due to limited thermal stability. In this study, we screened a thermostable L-ASNase gene from thermophile bacteria and expressed it in Aspergillus niger to reduce acrylamide content in French fries.
