Discussion of Yu & Meng’s Paper

چکیده
We begin by congratulating Professors Yu and Meng on an outstanding paper, and thanking Professor Levine for giving us the opportunity to discuss their work. Our discussion focuses mainly on the GIS & ASIS algorithms. Section 1 concerns the relationship between the GIS and sandwich algorithms. In Section 2, we consider a family of toy GIS algorithms based on the bivariate normal distribution, and show how this family is related to the toy example in Section 2 of Yu & Meng (2011) (hereafter Y&M). Finally, in Section 3, we provide a simple example of a non-reversible GIS algorithm.

In the present study, dormancy and germination requirements were investigated in seeds of Citrullus colocynthis (L.). Seeds were subjected to 10 pretreatments in the present study. These pretreatments included hot water (100° C) followed by the seeds placed between double layered filter paper moistened with 5 ml of distilled water and kept at 28 - 30 °C, sulphuric acid (98% v/v), for 30 min fo...
متن کاملTraceability improvements of a new RFID protocol based on EPC C1 G2
Radio Frequency Identification (RFID) applications have spread all over the world. In order to provide their security and privacy, researchers proposed different kinds of protocols. In this paper, we analyze the privacy of a new protocol, proposed by Yu-Jehn in 2015 which is based on Electronic Product Code Class1 Generation 2 (EPC C1 G2) standard. By applying the Ouafi_Phan privacy model, we s...
متن کاملRsc115: Sampling Bias and Logistic Models
Biased sampling It is worth re-stating the point made in section 3.3, using Meng’s notation in which Oi = 1 indicates that unit i will volunteer if asked. We distinguish between the conditional distribution pn(x,y |o ≡ 1) given that a fixed sample of n individuals happens to have no refusers, and the distribution po=1(x,y) for the first n volunteers. In a random-effects model where the response...

Objective(s): Yu-Ping-Feng-San (YPFS) is a classical traditional Chinese medicine that is widely used for treatment of the diseases in respiratory systems, including chronic obstructive pulmonary disease (COPD) recognized as chronic inflammatory disease. However, the molecular mechanism remains unclear. Here we detected the factors involved in transforming growth factor beta 1 (TGF-β1)/Smad2 si...
