Penn Station stabbing victim slams Mamdani, DA Bragg for suspect being free on streets
A Penn Station stabbing victim is calling out New York City Mayor Zohran Mamdani and Manhattan District Attorney Alvin Bragg while recounting the "crazy" scene on "Fox & Friends. ""I've got to blame the administration, starting with Mamdani and Bragg," victim Henry Obadiah said on Tuesday. The suspect, later identified as 51-year-old Hector Deleon, reportedly has a criminal history on "both sides of the river" in New York and New Jersey, according to local news reports.
The Bragg Frequency Convertor: A Meeting Between Spatial and Temporal Periodicities For Selective Parametric Frequency Translation
arXiv:2603.07124v2 Announce Type: replace Abstract: This study introduces the Bragg Frequency Converter, a spatiotemporal-periodic grating concept that extends conventional Bragg gratings into the dynamic domain for pure parametric frequency conversion. By selectively time-modulating either the high-index or low-index layers of a quarter-wave stack, the structure achieves directional frequency conversion: high-index modulation yields efficient down-conversion, while low-index modulation...
Machine-learning surrogate model for one-dimensional GaAs/Al$_{0.3}$Ga$_{0.7}$As distributed Bragg reflector spectra
arXiv:2606.08108v1 Announce Type: new Abstract: We present a Gaussian-process (GP) surrogate model for the normal-incidence reflectance spectrum of one-dimensional GaAs/Al$_{0.3}$Ga$_{0.7}$ distributed Bragg reflectors (DBRs). A Latin-hypercube dataset of 1500 transfer-matrix-method (TMM) simulations is used to train and evaluate the model. Principal component analysis reduces the spectral output to 26 components; one GP is fitted per component.
Bragg-enhanced time-domain Brillouin scattering from a propagating acoustic grating
Announce Type: new Abstract: Generation and detection of coherent phonons in semiconductors by femtosecond optical pulses is a powerful tool for high-frequency acoustic control of their electronic properties. Here, we demonstrate a propagating one-dimensional acoustic grating in bulk semiconductors using above-band-gap excitation by a train of laser pulses with high repetition rate of 1 GHz. This approach enables shaping of the coherent acoustic phonon spectrum and leads to a significant...

Anti-symmetric Multimode Waveguide Grating-Assisted Narrowband MZI for Programmable Spectral Shaping Units
Announce Type: new Abstract: We present a narrowband integrated Mach-Zehnder interferometer (MZI) capable of precise transmission control within a targeted wavelength band while maintaining out-of-band transparency. This functionality enables its use as a fundamental building block for fully programmable on-chip spectral shaping. The device is implemented on a novel dual-mode (TE0/ TE1) transmission platform, where anti-symmetric multimode waveguide Bragg gratings (AM-WBGs) and asymmetric...
Observation of spectral mode splitting in a pump-enhanced ring cavity for mid-infrared generation
arXiv:2606.05598v1 Announce Type: new Abstract: We report on experimental and theoretical investigation of mode-splitting dynamics in a ring cavity under the perturbation of fractional Bragg reflection from a periodically-poled nonlinear crystal. Counterintuitively, pronounced mode splitting in the spectral domain could been observed even with a tiny intensity reflection of 0.0003. The breaking of running-wave operation in the ring-cavity configuration resulted in comparable circulating...
Effect of introducing viscoelastic polyurethane on the dispersion and vibration isolation efficiency of chiral phononic crystals
arXiv:2606.01272v1 Announce Type: new Abstract: Phononic crystals, a sequence of masses and (damped) springs, are being used more and more in practical applications, exploiting Bragg bandgaps to attenuate vibration transmission in a wide frequency range. In particular, chiral phononic crystals have demonstrated their ability to achieve low frequency bandgaps while maintaining a high static stiffness, and thus load bearing capacities. However, tuning of the bandgap frequencies is non-trivial...

Why some homeowners like Meg are at risk of slipping into negative equity
Falling house prices bring relief for some while a financial nightmare for others Thu 4 Jun 2026 at 4:50am In short: Some who have recently bought into Australia's property market may have slipped into negative equity and owe the banks more than their homes are worth. A decline in property prices has pulled the government's recently expanded 5 per cent deposit scheme into focus. What's next: The treasurer says he is not worried about those at risk of falling into negative equity, while the...
