INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]
, 2016 Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

, 2013 We demonstrate how meshfree finite difference methods can be applied to solve vector Poisson problems with electric boundary conditions. In these, the tangential velocity and the incompressibility of the vector field are prescribed at the boundary.

Who Does Bogotá “Care” for? Care Blocks, Care Workers and the Sustainable Development Goals
Sustainable Development, EarlyView.ABSTRACT This paper critically examines Bogotá's District Care System within the framework of urban social sustainability and the Sustainable Development Goals (SDGs). Focusing on the Care Blocks (Manzanas del Cuidado), it employs a mixed‐methods approach—legal analysis, interviews, testimonies, surveys, and InfoCuidado data—to explore the paradox of a

Extreme Weather Events and Agricultural Total Factor Productivity Growth
Southern Economic Journal, EarlyView.ABSTRACT The productivity of the agricultural sector is crucial for food security in a changing climate. This study estimates the impacts of extreme weather events on agricultural total factor productivity (TFP) growth, contributing to a more comprehensive understanding of the effects of climate change on agriculture.

Detection of high-order Lamb waves using an end-face injection of ultrasonic pulses
Results in Physics, 2019 In this work, we report the time-of-flight detection of high-order Lamb waves by using an end-face injection of ultrasonic pulses in plates. We used two piezoelectric transducers attached to the opposite edges of a rectangular plate. We applied the Short

Supersymmetric Barotropic FRW Model and Dark Energy
, 2009 Using the superfield approach we construct the $n=2$ supersymmetric lagrangian for the FRW Universe with barotropic perfect fluid as matter field. The obtained supersymmetric algebra allowed us to take the square root of the Wheeler-DeWitt equation and ...
