On propagation characteristics of ultrasonic guided waves in helical strands by Zhang, Hongyan, Li, Jian, Jiang, Can, Chen, Shili, Fan, Zheng, Liu, Yang

“…The essence of this method is the mutual transformation principle of wave solution and vibration solution. To adapt to the helical structure of steel strands, this paper proposes a helical coordinate system and twisted coordinate system and deduces the corresponding wavenumber conversion formula. …”

Helicity amplitude analysis of χ cJ → ϕϕ by Ablikim, M, Achasov, MN, Adlarson, P, Albrecht, M, Aliberti, R, Amoroso, A, An, MR, An, Q, Bai, XH, Bai, Y, Bakina, O, Baldini Ferroli, R, Balossino, I, Ban, Y, Batozskaya, V, Becker, D, Begzsuren, K, Berger, N, Bertani, M, Bettoni, D, Bianchi, F, Bloms, J, Bortone, A, Boyko, I, Fischer, K, Gilman, A, Malde, S, Tat, M, Wilkinson, G, Zhang, Y

“…The branching fractions of the decays χcJ→ ϕϕ (J = 0, 1, 2) are determined to be (8.59 ± 0.27 ± 0.20) × 10−4, (4.26 ± 0.13 ± 0.15) × 10−4, and (12.67 ± 0.28 ± 0.33) × 10−4, respectively, which are the most precise measurements to date. From a helicity amplitude analysis of the process ψ(3686) → γχcJ, χcJ→ ϕϕ, ϕ → K+K−, the polarization parameters of the χcJ→ ϕϕ decays are determined for the first time.…”

Improvements of FDK-type helical cone-beam CT imaging by Liang, Hong Zhu

“…The modern FDK-type algorithms suffer from two main limitations of the data collection: the cone-shaped projection volume and the helical scanning pitch. Once the cone-beam angle becomes relatively large or the helical scanning is relatively fast, the artifacts would unavoidably appear on the images reconstructed by the existing FDK-type algorithms. …”

Design and analysis of multiple degree-of-freedom electrical machines with helical motion by He, Yaojie

“…They can be regarded as the combination of several two degree-of-freedom motions, which are classified as the rotary-rotary type, linear-linear type, and rotary-linear type (i.e., spheric, planar, and helical motions, respectively). Among them, extensive investigations have been made on realizing helical motion based on integrated electric machines. …”

Rationalisation of antifungal properties of α-helical pore-forming peptide, mastoparan B by Lim, Edward Jianyang, Goh, Eunice Tze Leng, Tram, Nhan Dai Thien, Periayah, Mercy Halleluyah, Ee, Rachel Pui Lai, Barkham, Timothy Mark Sebastian, Poh, Zhi Sheng, Verma, Navin Kumar, Lakshminarayanan, Rajamani

“…We show that MB susceptibility of phylogenetically distant non-candida albicans can vary and be described by different intrinsic physicochemical parameters of pore-forming α-helical peptides. These findings have potential therapeutic implications for the design and development of safe antifungal peptide-based drugs.…”
