The Porous germanium Efficient Epitaxial LayEr Release (PEELER) process is introduced allowing the fabrication of wafer scale detachable monocrystalline Ge nanomembranes compatible with III–V material growth on porous and substrate reuse.

Three algorithms — CubeMiner, Trias, and Data-Peeler — have been recently proposed to mine closed patterns in ternary relations, i.e., a generalization of the so-called formal concept extraction from binary relations. In this paper, we consider the specific context where a ternary relation denotes the value of a graph adjacency matrix (i. e., a Vertices × Vertices matrix) at different timestamp...

Set pattern discovery from binary relations has been extensively studied during the last decade. In particular, many complete and efficient algorithms which extract frequent closed sets are now available. Generalizing such a task to n-ary relations (n ≥ 2) appears as a timely challenge. It may be important for many applications, e.g., when adding the time dimension to the popular objects × feat...

Abstract Using three-dimensional particle-in-cell simulations, we further investigate the electron and ion acceleration from femtosecond laser–plasma peeler scheme which was proposed in our recent paper (Shen et al 2021 Phys. Rev. X 11 041002). In addition to standard setup where a laser pulse impinges on an edge of single tape target, two new variants i.e. parallel cross were proposed, strong ...

Through-bolt with dowel-nut connectors are commonly used in furniture where high strength mechanical connections are required. During early periods of use, dowel-nuts were often called barrel nuts (Eckelman 1977), but the term “dowel-nut” is more descriptive, and the author has referred to them as such in the above and all subsequent publications (Eckelman 1989, 1999; Eckelman and Erdil 2000). ...

A mathematical model for predicting the peeling efficiency of a cassava peeler was developed using dimensional analysis based on Buckingham' s pi theorem. The validated data from experimental studies which revealed maximum coefficient determination R2 = 0.8366 between measured and predicted values. proved appropriate in estimating peel removal by up to 83.66%. There no significance difference v...
