PFD or PDF: Rethinking the Probability of Failure in Mitigation Safety Functions
SIL (Safety Integrity Level) allocation plays a crucial role in defining the design requirements for Safety Functions (SFs) within high-risk industries. SIL is typically determined based on the estimated Probability of Failure on Demand (PFD), which must remain within permissible limits to manage risk effectively. Extensive research has been conducted on determining target PFD and SIL, with a stronger emphasis on preventive SFs than on mitigation SFs. In this paper, we address a rather conceptu…

1/2 Eräässä webinaarissa SFS:n edustaja viittasi tietyn standardiperheen olemiseen "markkinoilla". On hyvä huomio, että niilläkin on markkina, ja markkinan ohessa taloudellinenkin ekosysteemi.
Niinpä tämänkin tuoteryhmän puitteissa pitäisi viranomaisten ja asiakkaiden kiinnittää huomiota siihen, miten käytetään määräävää markkina-asemaa ja miten tehdään markkinointia ja myyntiä.

Site Frequency Spectrum in stationary branching populations
This paper explores the Site Frequency Spectrum (SFS) in stationary branching populations. We derive estimates for the SFS associated with a sample from a continuous-state branching process conditioned to never go extinct, utilizing a quadratic branching mechanism. The genealogy of such processes is represented by a real tree with a semi-infinite branch, and we compute the expectation of the SFS under the infinitely-many-sites assumption as the sample size approaches infinity. Additionally, we …

The physics of superconductor-ferromagnet hybrid structures
In this review, we summarize the theoretical foundations underlying a variety of phenomena in superconductor-ferromagnet (SF) hybrid structures, with a focus on recent advances in several key areas. These include: (i) the fundamental understanding of proximity effects in SF-based systems; (ii) spin-valve effects in SF and SFS Josephson junctions; and (iii) the design and realization of superconducting memory elements, particularly in SIsF-type Josephson junctions. We also discuss the experiment…

Segment-Factorized Full-Song Generation on Symbolic Piano Music
We propose the Segmented Full-Song Model (SFS) for symbolic full-song generation. The model accepts a user-provided song structure and an optional short seed segment that anchors the main idea around which the song is developed. By factorizing a song into segments and generating each one through selective attention to related segments, the model achieves higher quality and efficiency compared to prior work. To demonstrate its suitability for human-AI interaction, we further wrap SFS into a web …

Originality of resonance and locking phenomena in $φ_{0}$ junction
We demonstrate the realization and interplay of two ferromagnetic resonances in the SFS $φ_0$ Josephson junction. One of the resonances that is realized under microwave radiation is the famous Kittel ferromagnetic resonance. The other is the Buzdin ferromagnetic resonance appearing as a result of interaction of superconducting current and ferromagnetic interlayer magnetization. Transformations of one type of resonance to another under variation in the parameters of external radiation and the p…

Spectroscopic measurements of graphite electrode erosion on the ZaP-HD sheared-flow-stabilized Z-pinch device
The ionizations per photon, or S/XB, method uses spectroscopic measurements of radiating impurity ions to determine the influx from a solid surface. It is highly useful as a non-perturbing, in-situ measure of the gross erosion flux of plasma-facing components (PFCs). In sheared-flow-stabilized (SFS) Z-pinch devices, the electrode supplies the plasma current and directly contacts the core Z-pinch plasma. Electrode erosion due to the large particle and heat fluxes affects electrode durability, wh…

Non-Hermitian Chiral Superfluids with a Complex Interaction
Recently, the influence of dissipation on a quantum system has attracted much attention, particularly on how the non-Hermitian terms modify the energy spectrum, band topology, and phase transition point. Motivated by the recent investigation of non-Hermitian $s$-wave superfluidity, we study the non-Hermitian chiral $p+ip$ superfluid (SF) with a complex-valued interaction, originating from inelastic scattering between fermions. We reformulate the non-Hermitian mean-field theory for chiral SFs an…
