The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has killed millions of ash (Fraxinus spp.) trees across North America. Classical biological control using introductions of parasitoid wasps may provide a sustainable appr

Children diagnosed with brain tumors have the lowest overall survival of all pediatric cancers. Recent molecular studies have resulted in the discovery of recurrent driver mutations in many pediatric brain tumors. However, despite these molecular adv

Objectives: This scoping review aims to (1) describe the scope and coverage of the body of literature on nonbiomedical practices used for enhancing fertility, (2) summarize and map the existing evidence on the extent and types of nonbiomedical practi

We use high-field, broadband terahertz (THz) pulses to nonlinearly excite a set of Raman active modes in centrosymmetric crystals. Using two-dimensional (2D) THz spectroscopy we can investigate photonic and phononic excitation and isolate the dominan

High-field terahertz (THz) spectroscopy is enabling the ultrafast study and control of matter in new and exciting ways. However, when intense electromagnetic pulses are used in any kind of pump-probe spectroscopy, several nonlinear excitation pathway

Coupling between optical phonons and light leads to the formation of phonon polaritons, resulting in important changes to the material dispersion. Commonly, the phonon-polariton dispersion curve has been determined by transient-grating impulsive stim

INTRODUCTION: Childhood thalamic gliomas are rare cancers, accounting for 5% of all pediatric brain tumors and are of glial origin. The recent WHO classification places thalamic tumors in the category of midline gliomas based on discoveries that indi

High-field terahertz (THz) spectroscopy is applied to nonlinearly excite the E phonon-polariton vibrational coordinate in LiNbO3. We compare three THz sources to show that by optimizing the THz waveform, we can drive the atomic motion to large amplit

Recent advances of ultrafast spectroscopy allow the capture of an entire ultrafast signal waveform in a single probe shot, which greatly reduces the measurement time and opens the door for the spectroscopy of unrepeatable phenomena. However, most sin

2016 41st International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz).
Single-shot detection of a terahertz (THz) electric-field transient has been demonstrated using a high-bandwidth oscilloscope. The THz modulation was imprinted on a chirped picosecond probe pulse via an electro-optic crystal, and the probe pulse was
