Stochastic frontiers: a semiparametric approach [PDF]
, 1983 This paper generalizes the results of Hausman and Taylor (1981), Schmidt and Sickles (1984), Cornwell, Schmidt and Sickles (1990) and Park and Simar (1992) to the efficient IV estimation of panel models in which the random effects are correlated with a subset of the regressors.

Advanced Science, EarlyView.Using field‐based holo‐omics, we demonstrate that developmental shifts in sorghum leaf metabolomes drive a noncanonical fungal succession from stress tolerators (S) through ruderals (R) to competitors (C). Antifungal metabolites in young leaves select for S strategists with expanded genomes, transient maltose pulses during flowering favor fast‐growing ...

Estimating fixed-effect panel stochastic frontier models by model transformation [PDF]
Traditional panel stochastic frontier models do not distinguish between unobserved individual heterogeneity and inefficiency. They thus force all time-invariant individual heterogeneity into the estimated inefficiency. Greene (2005) proposes a true fixed-

Advanced Science, EarlyView.SPARK decodes structure‐property relationships in anion exchange membranes (AEMs) via a chemically informed dual‐channel graph attention network (DEGAT) that explicitly captures microphase separation. It outputs five‐level grades for hydroxide conductivity and alkaline stability and highlights relevant key structural units, enabling robust pre ...

FARMERS RESOURCE – USE AND TECHNICAL EFFICIENCY IN COWPEA PRODUCTION IN NIGERIA [PDF]
In Nigeria, the use of stochastic frontier to estimate farm level efficiency effects is still at the rudimentary level and is beginning to build up. Few studies have been undertaken but there is dearth need for more empirical studies on this important ...

Investigating Phase Separation in Genome Folding via Multiscale Computational Modeling
Advanced Science, EarlyView.Phase separation is emerging as a multiscale organizing principle of genome folding across scales, from nucleosomes and transcriptional condensates to chromatin domains and nuclear compartments. By integrating physics‐based simulations with data‐driven inference, computational modeling now links molecular interactions to nuclear architecture and points

Efficiency of Large Scale Manufacturing in Pakistan : A Production Frontier Approach [PDF]
This paper examines the efficiency of the large scale manufacturing sector of Pakistan using the stochastic production frontier approach. A stochastic production frontier is estimated for two periods1995-96 and 2000-01for 101 industries at the 5-digit ...

Advanced Science, EarlyView.The TopCas platform utilizes an engineered DNA‐RNA chimeric circular crRNA to establish topology‐gated control over CRISPR‐Cas12a activity, enabling target‐triggered self‐catalytic amplification (preamplification‐free). This system seamlessly integrates highly sensitive molecular diagnostics with conditionally controlled gene editing, demonstrating ...

Advanced Science, EarlyView.Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.
