Rank‐based estimation of propensity score weights via subclassification
Canadian Journal of Statistics, EarlyView.Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.

Optimal Seismic Design of High‐Rise Buildings With Outrigger Tuned Inertial Mass Damper
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper presents a novel optimization method for designing a system with a tuned inertial mass electromagnetic transducer (TIMET) damped outrigger (DO) for high‐rise buildings subjected to earthquakes. The DO system consists of the TIMET devices, which attach vertically between the outrigger and the perimeter columns.

Radius exponent in elastic and rigid arterial models optimized by the least energy principle
Physiological Reports, 2014 It was analyzed in normal physiological arteries whether the least energy principle would suffice to account for the radius exponent x. The mammalian arterial system was modeled as two types, the elastic or the rigid, to which Bernoulli's and Hagen ...

Scaling‐Aware Rating of Poisson‐Limited Demand Forecasts
Journal of Forecasting, EarlyView.ABSTRACT Forecast quality should be assessed in the context of what is possible in theory and what is reasonable to expect in practice. Often, one can identify an approximate upper bound to a probabilistic forecast's sharpness, which sets a lower, not necessarily achievable, limit to error metrics.

Estimation of cavitation limits from local head loss coefficient [PDF]
, 2008 Cavitation effects in valves and other sudden transitions in water distribution systems are studied as their better understanding and quantification is needed for design and analysis purposes and for predicting and controlling their operation.

Steiner Triple Systems With High Discrepancy
Journal of Combinatorial Designs, EarlyView.ABSTRACT In this paper, we initiate the study of discrepancy questions for combinatorial designs. Specifically, we show that, for every fixed r ≥ 3 $r\ge 3$ and n ≡ 1 , 3 ( mod 6 ) $n\equiv 1,3\,(\mathrm{mod}\,6)$, any r $r$‐colouring of the triples on [ n ] $[n]$ admits a Steiner triple system of order n $n$ with discrepancy Ω ( n 2 ) ${\rm{\Omega }}({
