Kentmere Kentmere PAN 400 (FF) English Alt Text: A black-and-white photo of a building with Middle Eastern-inspired architecture. The sign reads “A THOUSAND AND ONE NIGHTS.” The facade features domed doorways and square tiles with geometric patterns. In front stands an octagonal fountain with star-shaped designs and a central column with water spouts. The scene evokes the fantasy and cultural richness of the Arabian Nights tales, blending storytelling themes with decorative architecture. 中文替代…
Kentmere Kentmere PAN 400 (FF) English Alt Text: A black-and-white urban scene featuring a stylized artificial tree sculpture beside a real tree with foliage. Behind them is a wall with a large mural or advertisement, showing abstract designs and cityscape elements. The mural includes partially obscured text and graphics. A person stands between the trees, blending into the shadows. The ground is paved with rectangular tiles, and a drainage grate runs across the bottom. The image contrasts nat…
Kentmere Kentmere PAN 400 (FF) English Alt Text: A black-and-white photo of a modern glass building in Beijing’s Sanlitun area. The facade displays large cartoon characters and bilingual text: “TAIKOO LI” in English and “太古里” in Chinese. Below, the phrase “奇境探险” translates to “Adventure in Wonderland.” A traffic light and street sign reading “三里屯路 / SANLITUN Rd” are visible in the foreground. The image captures the vibrant, commercial atmosphere of a popular shopping and lifestyle district, bl…
Kentmere Kentmere PAN 400 (FF) English Alt Text: A black-and-white photo of a tall construction crane partially hidden by tree branches. The crane has a lattice structure and a cabin near the base of its arm, which extends diagonally upward. The branches frame the image from the top and right, creating a contrast between the industrial machinery and nature. The sky is mostly clear with faint clouds, giving the scene a quiet, contemplative mood. The juxtaposition of steel and leaves evokes them…

Crab-waist interaction region design and integration for the Super Tau-Charm Facility
The Super Tau-Charm Facility (STCF) is a new-generation $e^+e^-$ collider proposed in China, designed to operate in the center-of-mass (CoM) energy range of 2-7 GeV. To achieve the design luminosity exceeding 5*10^34 cm^-2s^-1 at the optimal CoM energy of 4 GeV, a large crossing angle combined with the crab-waist correction scheme is adopted. However, this scheme introduces strong nonlinearities in the interaction region (IR) due to the extremely low vertical beta function of beta_y* <=1 mm, wh…

Missing Beats: Dark Matter Silences Short-Period Cepheids in the Galactic Center
Upcoming near-infrared facilities (e.g., JWST/NIRCam, ELT/MICADO) will dramatically increase the detectability of galactic center Cepheids despite extreme extinction at optical wavelengths. In this work, we study the impact of dark matter (DM) annihilation on Cepheid stars in the inner parsec of the Milky Way. We show that at densities $ρ\sim 10^5 \, \text{GeV} \, \text{cm}^{-3}$, blue-loop evolution can be suppressed, preventing the formation of low-mass ($3$-$6 \, M_\odot$) short-period ($1$…

Multi-Speaker DOA Estimation in Binaural Hearing Aids using Deep Learning and Speaker Count Fusion
For extracting a target speaker voice, direction-of-arrival (DOA) estimation is crucial for binaural hearing aids operating in noisy, multi-speaker environments. Among the solutions developed for this task, a deep learning convolutional recurrent neural network (CRNN) model leveraging spectral phase differences and magnitude ratios between microphone signals is a popular option. In this paper, we explore adding source-count information for multi-sources DOA estimation. The use of dual-task trai…

Engaging and Educating Eclipse Observers Through Workshops, Media, Planetarium shows and Citizen Science
The Heliophysics Big Year was an extended year where major solar events engaged the public. It included two eclipses (annular on October 14, 2023 and total on April 8, 2024), plus solar max and the Parker Solar Probe perihelion December 24, 2024. After the eclipse of 2017, many millions more Americans planned to view the solar corona. We expanded our eclipse website with activities, citizen science projects, resources, training videos, equipment, and external links. We were the Southwest Region…
