Thunderella: Blockchains with Optimistic Instant Confirmation
blockchains optimistic responsiveness
2017/9/25
State machine replication, or “consensus”, is a central abstraction for distributed systems where a set of nodes seek to agree on an ever-growing, linearly-ordered log. In this paper, we propose a pra...
Double-spending Prevention for Bitcoin zero-confirmation transactions
Bitcoin double-spending
2017/5/11
Zero-confirmation transactions, i.e., transactions that have been broadcast but are still pending to be included in the blockchain, have gained attention in order to enable fast payments in Bitcoin, s...
Novel Confirmation and the Underdetermination of Scientific Theory Building

2016/6/12
The extra value of novel confirmation over accommodation is explained based on an analysis of the underdetermination of scientific theory building. Novel confirmation can provide information on the nu...
How Strong is the Confirmation of a Hypothesis by Significant Data?
significance tests Bayesianism confirmation likelihoodism falsification inference to the best explanation
2016/6/12
The aim of the article is to determine how much a hypothesis H is actually confirmed if it has successfully passed a classical significance test. Bayesians have already raised many serious objections ...
Climate Models,Calibration and Confirmation
confirmation calibration tuning double-counting climate science Bayesianism
2016/5/31
We argue that concerns about double-counting -- using the same evidence both to calibrate or tune climate models and also to confirm or verify that the models are adequate --deserve more careful scrut...
While Bayesian analysis has enjoyed notable success with many particular problems of inductive inference, it is not the one true and universal logic of induction. I review why the Bayesian approach fa...
Review: Confirmation of Resistance to Herbicides and Evaluation of Resistance Levels
Dose–response assay molecular-based assay quick tests sampling whole-plant assay
2015/12/21
As cases of resistance to herbicides escalate worldwide, there is increasing demand from growers to test for weed resistance and learn how to manage it. Scientists have developed resistance-testing pr...
Confirmation of the Basic Psychological Needs in Exercise Scale (BPNES) with a sample of people who do healthy exercise
Self-determination psychological mediators
2015/5/8
This study aimed to cross-validate the psychometric properties
of the Basic Psychological Needs in Exercise Scale (BPNES) by
Vlachopoulos and Michailidou (2006) in a Spanish context.
Innovation and the Challenge of Novelty:The Novelty-Confirmation-Transformation Cycle in Software and Science
Innovation and Invention Knowledge Acquisition Knowledge Use and Leverage Infrastructure Science Creativity Software Value
2015/4/24
Innovation requires sources of novelty, but the challenge is that not all sources lead to innovation, so its value needs to be determined. However, since ways of determining value stem from existing k...
We report the spectroscopic confirmation of a submillimeter galaxy (SMG) at z = 4.547 with an estimated LIR = (0.5-2.0) × 1013 L. The spectra, mid-IR, and X-ray properties indicate the bolometric lumi...
We show that world trade network datasets contain empirical evidence that the dynamics of innovation in the world economy follows indeed the concept of creative destruction, as proposed by J.A. Schump...
Spectroscopic Confirmation of Three z-Dropout Galaxies at z = 6.844 - 7.213: Lyman Alpha Demography of z ~ 7 Galaxies
Spectroscopic Confirmation z-Dropout Galaxies Lyman Alpha Demography z ~ 7 Galaxies
2011/7/15
We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in the SDF and GOODS-N. For 3 out of 11 objects, we detect an emission line at ~ 1um with a signal-to-noise rati...
Spectroscopic confirmation of z~7 LBGs: probing the earliest galaxies and the epoch of reionization
Spectroscopic confirmation earliest galaxies epoch reionization
2011/7/7
We present the final results from our ultra-deep spectroscopic campaign with FORS2 at the ESO/VLT for the confirmation of z~7 "z--band dropout" candidates selected from our VLT/Hawk-I imaging survey o...
