Randomized, Double‐Blind, Placebo‐Controlled, Single Ascending Dose Trial of Synthetic Preimplantation Factor in Autoimmune Hepatitis

Hepatology Communications, 2018
Preimplantation factor (PIF) is an evolutionary conserved peptide secreted by viable embryos which promotes maternal tolerance without immune suppression. Synthetic PIF (sPIF) replicates native peptide activity.

On the Study of the Single-stage Hole-flanging Process by SPIF

Procedia Engineering, 2015
Recent studies show the capability of single-point incremental forming to perform successfully hole-flanging operations using multi-stage strategies. The aim of this work is to investigate the ability of the SPIF process to perform hole-flanges in a single stage, contributing to a better understanding of the formability of the sheet in this demanding ...

Research on the Radial Accuracy of Ultrasonic Vibration‐Assisted Single Point Incremental Forming Parts

International Journal of Aerospace Engineering, Volume 2019, Issue 1, 2019., 2019
With the more and more complexity demands of the market, the geometric accuracy of the part has become the main factor restricting the development of single point incremental forming technology (SPIF). For this reason, with the truncated cone as the target part, the radial accuracy error generation mechanism was analyzed from the aspects of sheet ...
