Article Abstract
The stochastic behaviour of ion channels can be described by a discrete model or by an approximate continuous approach. While the discrete approach is exact, it is also less computationally efficient, and so the continuous model is often the method of choice since it allows for incorporation into a multiscale environment. However, in recent years the accuracy of the stochastic continuous approach for calculating statistics of certain quantities in the Hodgkin-Huxley model has come into question. In this paper, we show that by correct formulation of the continuous model, the first two moments in the number of open sodium and potassium channels in the Hodgkin-Huxley model, calculated under voltage clamp conditions using the continuous approach are in good agreement with those obtained from the discrete model.

Stemming from human immune organs, tonsil-derived mesenchymal stem cells (TMSCs) hold unique strengths in differentiation potential and immune regulatory functions. These characteristics make them valuable for therapeutic applications, particularly in regenerative medicine and autoimmune disease treatment, as they can modulate immune responses and promote tissue repair. Their ability to interact with various cell types and secrete a range of bioactive molecules further enhances their role in orchestrating healing processes, making them a promising avenue for innovative therapies aimed at restoring balance in the immune system and facilitating recovery from injury or disease.

Pattern recognition-based myoelectric control is traditionally trained with static or ramp contractions, but this fails to capture the dynamic nature of real-world movements. This study investigated the benefits of training classifiers with continuous dynamic data, encompassing transitions between various movement classes. We employed both conventional (LDA) and deep learning (LSTM) classifiers, comparing their performance when trained with ramp data, continuous dynamic data, and an LSTM pre-trained with a self-supervised learning technique (VICReg).

Background: Single-position prone transpsoas lateral lumbar interbody fusion (PTP-LLIF) is an evolving minimally invasive surgery technique that merges the biomechanical and anatomical advantages of prone positioning with the LLIF approach. While PTP-LLIF enhances lumbar lordosis restoration and operative efficiency by eliminating patient repositioning, it presents unique ergonomic and visualization challenges for surgeons. This technical report describes a novel modification of the technique using the Teligen camera to improve intraoperative visualization and reduce surgeon fatigue.

With the rapid advancement in autonomous vehicles, 5G and future 6G communications, medical imaging, spacecraft, and stealth fighter jets, the frequency range of electromagnetic waves continues to expand, making electromagnetic interference (EMI) shielding a critical challenge for ensuring the safe operation of equipment. Although some existing EMI shielding materials offer lightweight construction, high strength, and effective shielding, they struggle to efficiently absorb broadband electromagnetic waves and mitigate dimensional instability and thermal stress caused by temperature fluctuations. These limitations significantly reduce their service life and restrict their practical applications.

The Abuse of Older People - Intervention Accelerator (AOP-IA) project aims to accelerate the development of effective interventions to prevent and reduce AOP aged 60 and older within the framework of the United Nations Decade of Healthy Ageing (2021-2030). The AOP-IA was launched in response to the global need for interventions with proven effectiveness, as few existing approaches have been rigorously evaluated. This paper focuses on the first two phases of the AOP-IA project, which involved conducting a systematic search, screening and evaluation process to identify candidate interventions ready to be rigorously evaluated in future stages of the project, as well as establishing a network of intervention developers.
