Sequential monitoring with conditional randomization tests
, 2012 Sequential monitoring in clinical trials is often employed to allow for early stopping and other interim decisions, while maintaining the type I error rate.

Optimal response and covariate-adaptive biased-coin designs for clinical trials with continuous multivariate or longitudinal responses [PDF]
, 2016 Adaptive randomization of the sequential construction of optimum experimental designs is used to derive biased-coin designs for longitudinal clinical trials with continuous responses.

Optimal Auctions for Correlated Buyers with Sampling [PDF]
, 2014 Cr\'emer and McLean [1985] showed that, when buyers' valuations are drawn from a correlated distribution, an auction with full knowledge on the distribution can extract the full social surplus.

The distribution of loss in two-treatment biased-coin designs [PDF]
Biostatistics, 2003 The paper compares randomized rules of the biased-coin type for the sequential allocation of treatments in a clinical trial. An important characteristic is the loss, which measures the increase in the variance of parameter estimates due to the imbalance caused by randomization. Simulations are used to find the small-sample distribution of loss.

Efficient randomized-adaptive designs
, 2009 Response-adaptive randomization has recently attracted a lot of attention in the literature. In this paper, we propose a new and simple family of response-adaptive randomization procedures that attain the Cramer--Rao lower bounds on the allocation ...

Measurement of statistical evidence on an absolute scale following thermodynamic principles [PDF]
, 2013 Statistical analysis is used throughout biomedical research and elsewhere to assess strength of evidence. We have previously argued that typical outcome statistics (including p-values and maximum likelihood ratios) have poor measure-theoretic properties:

Advanced Functional Materials, EarlyView.Lithium‐ion batteries (LIBs) remain central to energy storage but suffer from slow ion transport and degradation. Here, we present a binder‐free Ti3C2Tx MXene/GnR hybrid electrode with a porous 3D architecture formed via freeze casting. The structure enhances conductivity, ion transport, and stability, delivering 401 mAh/g, ∼97% efficiency, and 92 ...

Robust Tests for Treatment Effect in Survival Analysis under Covariate-Adaptive Randomization
, 2019 Covariate-adaptive randomization is popular in clinical trials with sequentially arrived patients for balancing treatment assignments across prognostic factors which may have influence on the response.

New paradoxical games based on Brownian ratchets [PDF]
, 2000 Based on Brownian ratchets, a counter-intuitive phenomenon has recently emerged -- namely, that two losing games can yield, when combined, a paradoxical tendency to win.
