We propose a framework for analyzing the sensitivity of counterfactuals to parametric assumptions about distribution latent variables in structural models. In particular, we derive bounds on as spans nonparametric neighborhoods given specification while other “structural” features model are maintained. Our approach recasts infinite‐dimensional problem optimizing counterfactual with respect (sub...

now, on February 24th, 1888. He was then just convalescing from an attack of remittent fever for which he had been treated in the hospital of the Burmah Military Police, to which corps lie belonged. As the battalion of Burmah Police was leaving Lueknow for Burmah, he was left behind at the depot of the 12th Kelat-i-Ghilzi. On admission he was weak and generally pulled down from the effects of t...

The crisis of 2007–2008 was a crisis of collateral. Since then, financial market participants – particularly in the euro area and the United States – have shown an increased appetite for secured lending. In short-term bank funding markets, there has been a pronounced shift towards repurchase arrangements. And covered bonds have gained in popularity in long-term funding markets. The cyclical fli...

Three cases of primary hyperhidrosis of no known cause, with excess sweating day and night, were treated using the same acupuncture points. The patients reported that their sweating decreased and that they felt better after the treatment.

Genetic robustness, the preservation of an optimal phenotype in the face of mutations, is critical to the understanding of evolution as phenotypically expressed genetic variation is the fuel of natural selection. The origin of genetic robustness, whether it evolves directly by natural selection or it is a correlated byproduct of other phenotypic traits, is, however, unresolved. Examining micro-...

Species loss in ecosystems can lead to secondary extinctions as a result of consumer-resource relationships and other species interactions. We compare levels of secondary extinctions in communities generated by four structural food-web models and a fifth null model in response to sequential primary species removals. We focus on various aspects of food-web structural integrity including robustne...

Steganography is a system that hides information in an application cover carrier like image, text, audio, and video. Considerable amount of work has been carried out by different researchers on this subject. Least Significant Bit (LSB) insertion method was more suspicious and low robustness against attacks. The objectives of this study were to analyse various existing system and implement a dyn...
