Fixing the Leaky Pipeline: Affirmative Action in Local Elite Colleges and Subject Choice

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT Women are largely underrepresented in STEM careers associated with higher labor market returns. This gender gap is even more stark in a context where societal biases are prevalent and female role models are lacking. This paper investigates the impact of an affirmative action (AA) policy implemented in an elite educational institution in India ...

Translation Invariant States on Twisted Algebras on a Lattice

open access: yes, 2009
We construct an algebra with twisted commutation relations and equip it with the shift. For appropriate irregularity of the non-local commutation relations we prove that the tracial state is the only translation-invariant ...

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

open access: yesWildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

Quantum optical effective-medium theory for layered metamaterials

open access: yes, 2016
The quantum optics of metamaterials starts with the question whether the same effective-medium theories apply as in classical optics. In general the answer is negative.

Multiterminal High‐Voltage Direct Current Projects: A Comprehensive Assessment and Future Prospects

open access: yesHigh Voltage, EarlyView.
ABSTRACT Multiterminal high‐voltage direct current (MT‐HVDC) systems are an important part of modern power systems, addressing the need for bulk power delivery and efficient renewable energy integration. This paper provides a comprehensive overview of recent advances in MT‐HVDC technology, including launched projects and ongoing initiatives.

Study on the Influence of Inconsistent Valve Parameters on LCC-HVDC Commutation and Operation

open access: yesIEEE Access, 2019
Line commutated converter high voltage direct current (LCC-HVDC) transmission has unique advantages and plays an irreplaceable role in the power system. It is of great significance to study the commutation process.

Schr\"odinger-Feynman quantization and composition of observables in general boundary quantum field theory

open access: yes, 2015
We show that the Feynman path integral together with the Schr\"odinger representation gives rise to a rigorous and functorial quantization scheme for linear and affine field theories.

Investigation of the Simplified Equivalent Circuit Model of the Post‐Arc Sheath Stage in DC Vacuum Circuit Breakers

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper presents a simplified equivalent circuit model (ECM) for the post‐arc sheath stage in DC vacuum circuit breakers and outlines the method for calculating circuit parameters using the particle‐in‐cell Monte Carlo collision (PIC‐MCC) method. The post‐arc sheath is modelled as a parallel combination of a variable resistor and a variable

Non-geometric Kaluza-Klein monopoles and magnetic duals of M-theory R-flux backgrounds

open access: yes, 2017
We introduce a magnetic analogue of the seven-dimensional nonassociative octonionic R-flux algebra that describes the phase space of M2-branes in four-dimensional locally non-geometric M-theory backgrounds.
