Between anaphora and deixis...the resolution of the demonstrative noun-phrase ‘that N’ [PDF]

open access: yes, 2011
Three experiments examined the hypothesis that the demonstrative noun phrase (NP) that N, as an anadeictic expression, preferentially refers to the less salient referent in a discourse representation when used anaphorically, whereas the anaphoric pronoun

Quantifying the latitudinal representivity of in situ solar wind observations [PDF]

open access: yes, 2020
Advanced space-weather forecasting relies on the ability to accurately predict near-Earth solar wind conditions. For this purpose, physics-based, global numerical models of the solar wind are initialized with photospheric magnetic field and coronagraph ...

Aero-elastic wind turbine design with active flaps for AEP maximization [PDF]

open access: yesWind Energy Science, 2018
In optimal wind turbine design, there is a compromise between maximizing the energy producing forces and minimizing the absolute peak loads carried by the structures.

The most similar predictor – on selecting measurement locations for wind resource assessment [PDF]

open access: yesWind Energy Science, 2020
We present the “most similar” method for selecting optimal measurement positions for wind resource assessment. Wind resource assessment is generally done by extrapolating a measured and long-term corrected wind climate at one location to a prediction

Validation of Aeroelastic Actuator Line for Wind Turbine Modelling in Complex Flows

open access: yesFrontiers in Energy Research, 2022
The actuator line method is a widely used technique to model wind turbines in computational fluid dynamics, as it significantly reduces the required computational expense in comparison to simulations using geometrically resolved blades.

Laparoscopic repair of a large interstitially incarcerated inguinal hernia. [PDF]

open access: yes, 2011
A 68 year old female presented for elective repair of an abdominal wall hernia. Preoperative CT imaging revealed a right inguinal hernia defect with hernia contents coursing cephalad between the external and internal abdominal oblique muscles.

Combined hydro-wind generation bids in a pool-based electricity market [PDF]

open access: yes, 2009
Present regulatory trends are promoting the irect participation of wind energy in electricity markets. The final result of these markets sets the production scheduling for the operation time, including a power commitment from the wind generators. However,

Investigation on the impact of design wind speed and control strategy on the performance of fixed-pitch variable-speed wind turbines [PDF]

open access: yes, 2017
Wind turbine blade design optimization remains one of the fundamental research areas for modern wind turbine technology. The general design process for fixed-pitch variablespeed wind turbine blades assumes the rated wind speed as the design wind speed ...

Utility of Computed Tomography Surveillance of Asymptomatic Infection in Children and Young Adults Before Allogeneic Hematopoietic Stem Cell Transplant

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.
