Balance™ methodology – converting carbon finance to biodiversity creation

open access: yesInternational Journal of Sustainable Energy, 2023
This paper addresses two interlinked problems in sustainable development and suggests a methodology to resolve them. The first is the reduction of atmospheric greenhouse gas emissions, especially carbon dioxide.

Quantum Spin Hall Effect and Topological Phase Transition in HgTe Quantum Wells [PDF]

open access: yesScience, 2006
We show that the quantum spin Hall (QSH) effect, a state of matter with topological properties distinct from those of conventional insulators, can be realized in mercury telluride–cadmium telluride semiconductor quantum wells.

Immunotherapy reverses glioma-driven dysfunction of immune system homeostasis

open access: yesJournal for ImmunoTherapy of Cancer, 2023
Background Glioma-induced immune dysregulation of the hematopoietic system has been described in a limited number of studies. In this study, our group further demonstrates that gliomas interrupt the cellular differentiation programming and outcomes of ...

Quantum Spin Hall Insulator State in HgTe Quantum Wells [PDF]

open access: yesScience, 2007
Recent theory predicted that the quantum spin Hall effect, a fundamentally new quantum state of matter that exists at zero external magnetic field, may be realized in HgTe/(Hg,Cd)Te quantum wells. We fabricated such sample structures with low density and

Impact of the industial activity on groudwater quality (case of study: El-Kalitoussa Region Northeast Algeria) [PDF]

open access: yesPresent Environment and Sustainable Development, 2022
The contamination of groundwater by toxic compounds even in low concentrations can compromise the exploitation of the resource for long periods. This work is in this theme.

Effects of life stage on eDNA detection of the invasive European green crab (Carcinus maenas) in estuarine systems

open access: yesEcological Indicators, 2021
Early and efficient detection of rare and invasive species is critical for the effective management of their populations. Environmental DNA (eDNA) detection techniques have been used for monitoring soft-bodied organisms (e.g., fishes) and some ...

Tracking sources and fate of groundwater nitrate in Kisumu City and Kano Plains, Kenya [PDF]

open access: yes, 2020
Groundwater nitrate (NO3−) pollution sources and in situ attenuation were investigated in Kisumu city and Kano plains. Samples from 62 groundwater wells consisting of shallow wells (hand dug, depth 15 m) were obtained during wet (May–July 2017) and dry ...

Backward Deep BSDE Methods and Applications to Nonlinear Problems

open access: yesRisks, 2023
We present a pathwise deep Backward Stochastic Differential Equation (BSDE) method for Forward Backward Stochastic Differential Equations with terminal conditions that time-steps the BSDE backwards and apply it to the differential rates problem as a ...

Methane Emissions from Abandoned Oil and Gas Wells in Canada and the United States.

open access: yesEnvironmental Science and Technology, 2020
Abandoned oil and gas wells are one of the most uncertain sources of methane emissions into the atmosphere. To reduce these uncertainties and improve emission estimates, we geospatially and statistically analyze 598 direct methane emission measurements ...
