“…We performed exact diagonaliza-tion of the four-state quantum Potts chain with moderate size and found that the eigenenergies of several low-energy states indeed deviate from the CFT predictions, which may be seen as the effect of marginally irrelevant perturbations. The effect of marginally irrelevant terms on the Klein bottle entropy is beyond the scope of the current work and will be reported elsewhere 49 .…”

Recently, entropy corrections on nonorientable manifolds such as the Klein bottle are proposed as a universal characterization of critical systems with an emergent conformal field theory (CFT). We show that entropy correction on the Klein bottle can be interpreted as a boundary effect via transforming the Klein bottle into an orientable manifold with nonlocal boundary interactions. The interpretation reveals the conceptual connection of the Klein bottle entropy with the celebrated Affleck-Ludwig entropy in boundary CFT. We propose a generic scheme to extract these universal boundary entropies from quantum Monte Carlo calculation of partition function ratios in lattice models. Our numerical results on the Affleck-Ludwig entropy and Klein bottle entropy for the q-state quantum Potts chains with q = 2, 3 show excellent agreement with the CFT predictions. For the quantum Potts chain with q = 4, the Klein bottle entropy slightly deviates from the CFT prediction, which is possibly due to marginally irrelevant terms in the low-energy effective theory.

“…There are a lot of ways of creating thin films. The ion beam assisted deposition (IBAD) [12], plasma-enhanced chemical vapour deposition (PECVD) [13], deposition in sputtering procedures [14], ink-jet printing technology [15] are among them. The article presents the results of research on the friction phenomenon of metallic layers produced in the process of physical vacuum deposition (PVD) [16].…”

The paper presents the results of research study on the phenomenon of friction of thin film electroconductive structure created on composite flexible substrate and results of measurement of the friction coefficient. Tribological tests were performed on T-01M tribotester. The measurement tests were conducted according to ASTM G133 standard with a minimum force of 1N. A ball-on-disc friction combination was used. The study was conducted at a fixed temperature of 28 ° C. Due to the nature of the tested samples, non-standard test parameters were used: test time 100 s, data acquisition frequency 10 Hz, slip velocity of the friction node 0.3 m/s on a radius of 11 mm. Based on the obtained results, the friction coefficient of the thin metallic layer Ag and Cu was determined. The obtained mean friction coefficient for a silver layer was 0.59, while for a thin copper layer 0.67. The knowledge of the determined coefficients will allow for effective and optimal use of the textronics materials tested in practical applications. The research methodology does not support determining the usage of the ball-on-disc pair.

“…[ 41 ] This sarcopenia is caused by a combination of multiple mechanisms, including immobilized and dysfunctional atrophy, impaired feeding, inflammation, sympathetic hyperactivation, and denervation. [ 43 ] In addition to sarcopenia, there is a partial shift in the type of fibers in skeletal muscle after stroke: Stroke survivors show a shift from slow‐twitch to fast‐twitch muscle fibers. [ 44 ] This shift leads to impaired metabolisms, such as increased tissue lactate and glycerol production, delayed and impaired glucose utilization, and slightly increased energy expenditure, [ 45 ] due to the easier fatigue of fast‐twitch muscle fibers.…”

Applying sensors in biomedical institutions and home‐based stroke rehabilitation is now a global research focus. In this review paper, the relationship between stroke diseases’ physiology mechanism and diverse sensors’ functionalities is detailed explained. The review starts by interpreting how stroke influences motion abilities and then introduces broadly adopted physical training methods. After, the working principles of sensors and their use to objectively provide patients’ body information for stroke rehabilitation status are discussed. The content of the paper aims to not only review the state‐of‐the‐art works of developing sensors for assisting in evaluating stroke patients’ status but also bridging the gap between medical staff and engineers.
