Astronomical Quantum Optics with Extremely Large Telescopes

, 2006
Modern optics focuses on photonics and quantum optics, studying individual photons, and statistics of photon streams. Those can be complex and carry information beyond that recorded by imaging, spectroscopy, polarimetry, or interferometry. Since [almost]

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

The medium size telescopes of the Cherenkov telescope array [PDF]

AIP Conference Proceedings, 2017
The Cherenkov Telescope Array (CTA) is the planned next-generation instrument for ground-based gamma-ray astronomy, covering a photon energy range of ~20 GeV to above 100 TeV. CTA will consist of the order of 100 telescopes of three sizes, installed at two sites in the Northern and Southern Hemisphere.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Shape of Yield Curves Under Instrument‐Based Parallel Shifts

Journal of Futures Markets, EarlyView.
ABSTRACT This paper studies the shape of zero and par yield curves through the carry and convexity of zero‐bond and par–swap butterflies under instrument‐based parallel shifts: the component instruments are held fixed, and each instrument's own quote receives the same additive shock.

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States

Irrigation and Drainage, EarlyView.
ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...

Leveraging Isomerization of Azo Dyes and Imines for the Facile Synthesis of Oxadiazepines and Related Heterocycles

Journal of Heterocyclic Chemistry, EarlyView.
A robust method for synthesizing substituted oxadiazepines and related heterocycles via intramolecular SNAr is detailed. Under mild conditions, this methodology has been leveraged to afford products of varying electronic and aryl nature in up to 99% yields.
