Type synthesis to design variable camber mechanisms
Advances in Mechanical Engineering, 2016 This article proposes multiple hinges’ type spectrum that provides an effective description of the multiple hinges of planar kinematic chains. The relationships between characteristic invariants are established and applied into type synthesis methods.

Asymmetric Synthesis of Scillascillin-Type Homoisoflavonoid
Organic LettersThe first asymmetric synthesis of a scillascillin-type homoisoflavonoid was reported. Key reactions for the asymmetric synthesis of benzocyclobutene include catalytic reductive desymmetrization of malonic ester and an intramolecular C-H activation of the methyl group.

Targeted Synthesis of Regioisomerically Pure Dodecasubstituted Type I Porphyrins Through the Exploitation of Peri-Interactions [PDF]
, 2020 A targeted synthesis of dodecasubstituted type I porphyrins that utilizes the reaction of unsymmetrical 3,4-difunctionalized pyrroles and sterically demanding aldehydes was developed. This way, type I porphyrins could be obtained as the only type isomers,

Leveraging Rust Types for Program Synthesis
Proceedings of the ACM on Programming Languages, 2023 The Rust type system guarantees memory safety and data-race freedom. However, to satisfy Rust's type rules, many familiar implementation patterns must be adapted substantially. These necessary adaptations complicate programming and might hinder language adoption. In this paper, we demonstrate that, in contrast to manual programming, automatic synthesis

BORON SYNTHESIS IN TYPE Ic SUPERNOVAE [PDF]
The Astrophysical Journal, 2010 We investigate the neutrino-process in an energetic Type Ic supernova (SN Ic) and resultant productions of the light elements including boron and its stable isotopes. SN Ic is a very unique boron source because it can produce boron through not only spallation reactions as discussed in Nakamura & Shigeyama (2004) but also the neutrino-process.

Total synthesis of lamellarins D, L, and N [PDF]
, 2006 Total synthesis of cytotoxic marine alkaloids, lamellarins D, L, and N, has been achieved by using Hinsberg-type pyrrole synthesis and palladium-catalyzedSuzuki-Miyaura coupling of the 3,4-dihydroxypyrrole bistriflate 6 as the key reactions.The total ...
