RBI to fully absorb forex risks, inflows may see $50bn boost
MUMBAI: Reserve Bank of India has opened the dollar tap by taking on the currency risk itself to draw in overseas money, while nudging state-owned borrowers to look abroad for cheaper funds. RBI will not charge any premium for swapping dollars raised through foreign currency non-resident bank FCNR(B) deposits, effectively absorbing the entire forex risk and allowing banks to offer higher returns to NRIs. In addition, FCNR(B) deposits of three to five years will be exempt from the cash...
Absorbing Discrete Diffusion for Speech Enhancement
arXiv:2602.22417v2 Announce Type: replace Abstract: Inspired by recent developments in neural speech coding and diffusion-based language modeling, we tackle speech enhancement by modeling the conditional distribution of clean speech codes given noisy speech codes using absorbing discrete diffusion. The proposed approach, which we call ADDSE, leverages both the expressive latent space of neural audio codecs and the non-autoregressive sampling procedure of diffusion models. To efficiently...
Visibly Transparent, Near-Infrared Absorbing Nanofluids Enable High-Efficiency and Safe Laser Lithotripsy
Laser lithotripsy (LL) is the gold standard for urinary stone management yet maximizing ablation efficiency while maintaining procedural safety remains clinically challenging. Here, we present a visibly transparent, near-infrared (NIR)-absorbing ITO@SiO2 nanofluid irrigation strategy that significantly enhances LL efficiency without compromising endoscopic visibility. By spectrally matching the absorption profile of ITO@SiO2 with the clinical Holmium:YAG laser wavelength, ablation efficiency...
Particle-in-Cell Simulation of the Parametric Decay Instability of Alfv\'en Waves with Absorbing Boundary Conditions
arXiv:2606.04932v1 Announce Type: new Abstract: The Alfv\'en wave parametric decay instability (PDI) facilitates energy transfer, plasma heating, and turbulence generation in space, astrophysical, and fusion plasmas. Most simulation studies of Alfv\'en wave PDI have focused on kinetic ions under periodic boundary conditions. Here, we present fully kinetic one-dimensional simulations (perpendicular wave-vector $k_\perp=0$) of the Alfv\'en wave PDI at low plasma beta using absorbing boundary...
Absorbing Complexity: An Interaction-Native Knowledge Harness for Financial LLM Agents
arXiv:2606.01886v1 Announce Type: new Abstract: Financial AI agents often fail for a simple reason: they make users carry the complexity. A user must repeatedly restate goals, risk preferences, portfolio context, past judgments, and shifting market assumptions, while the agent answers, retrieves, acts, and forgets. In finance, this is not just inconvenient.
Inverse Design of Realizable Metasurface based Absorbers using Improved Conditioning and Diversity Enhanced Progressively Growing GANs
arXiv:2606.05849v1 Announce Type: cross Abstract: Metasurfaces enable precise manipulation of electromagnetic waves for applications such as beam steering, sensing, and stealth technology. However, inverse design of metasurfaces with targeted EM responses remains challenging due to the computational expense of iterative full wave simulation driven optimization and the limited conditioning fidelity and diversity of existing generative approaches. To address these challenges, this paper...
Physics Guided Conditional Diffusion Framework for Generative Inverse Design of Manufacturable Metasurface based Absorbers
Announce Type: replace Abstract: Inverse design of metasurfaces under continuous electromagnetic constraints requires generation of geometries that simultaneously satisfy stringent spectral specifications and remain manufacturable. Conventional approaches based on iterative full wave simulations are computationally prohibitive for large design spaces, while existing generative models often suffer from poor conditional controllability and limited fabrication awareness. In this regard, we...

Tunable Mid-Infrared Chiral Selective Absorber Based on Asymmetric V-Shaped Metasurfaces Driven by Chiral quasi-Bound State in the Continum
Announce Type: new Abstract: Efficient discrimination of circularly polarized light (CPL) is of great significance in photonics. In this study, we propose a nanophotonic device based on asymmetric V-shaped metasurfaces that exhibits strong discrimination between left- and right-circularly polarized (LCP and RCP) light at the resonant wavelengths of the absorption spectra. The chiral-selective response originates from a quasi-bound state in the continuum (qBIC) mode enabled by controlled...
Brits urged to sprinkle baking soda on their beds this week
Brits urged to sprinkle baking soda on their beds this week As temperatures soar towards the weekend, an expert has shared how baking soda can come in very handy. Brits could be on course for another heatwave by the weekend, with temperatures of up to 28C forecast. As the mercury climbs across the UK, many people are likely to sweat more in bed than they would during the winter months, with much of that moisture ending up absorbed by their mattress.
