Precise Measurement of the e^{+}e^{-}→D_{s}^{+}D_{s}^{-} Cross Section at Center-of-Mass Energies from Threshold to 4.95 GeV.

Using the e^{+}e^{-} collision data collected with the BESIII detector operating at the BEPCII collider, at center-of-mass energies from the threshold to 4.95 GeV, we present precise measurements of the cross section for the process e^{+}e^{-}→D_{s}^{+}D_{s}^{-} using a single-tag method. The resulting cross section line shape exhibits several new structures, thereby offering an input for a future coupled-channel analysis and model tests, which are critical to understand vector charmonium-like states with masses between 4 and 5 GeV.

Simultaneous Unbinned Differential Cross-Section Measurement of Twenty-Four Z+jets Kinematic Observables with the ATLAS Detector.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Isolation of Human BAMBIhighMFGE8high Umbilical Cord-Derived Mesenchymal Stromal Cells.

Umbilical cord-derived mesenchymal stromal/stem cells (UC-MSCs) present low immunogenicity and potent immunomodulatory effects for treating various diseases. Human UC-MSCs are a heterogeneous population consisting of three main subpopulations with different cell shapes, proliferation rates, differentiation abilities, and immune regulatory functions. Previously, BAMBIMFGE8 UC-MSCs, the first subgroup successfully isolated from UC-MSCs were found to fail to alleviate lupus nephritis.

Salvianolic acid A promotes bone-fracture healing via balancing osteoblast and osteoclast differentiation.

Nonunion is a significant complication in fracture management for surgeons. Salvianolic acid A (SAA), derived from the traditional Chinese plant Salviae miltiorrhizae Bunge (Danshen), exhibits notable anti-inflammatory and antioxidant properties. Although studies have demonstrated its ability to promote osteogenic differentiation, the exact mechanism of action remains unclear.

Beam Scanning with Ultra-Low Sidelobes and In-Band Ultra-Low Scattering Characteristics Empowered by Single Space-Time-Coding Radiation-Scattering Metasurface.

The integrated modulation of radiation and scattering provides an unprecedented opportunity to reduce the number of electromagnetic (EM) apertures in the platform while simultaneously enhancing communication and stealth performance. Nevertheless, achieving full-polarization, arbitrary amplitude, and phase modulation of radiation scattering remains a challenge. In this paper, a strategy that realizes space-time coding of radiation scattering within the same frequency band, which enables the simultaneous and independent modulation of amplitude and phase, is proposed.

Reassessing the Role of Low PSA in Prognosis Across Grades of Prostate Cancer: A Cohort Study.

Multi-band reconfigurable microwave photonic transceiver towards high-performance integrated radar.

As an effective approach to overcome the electronic bottlenecks of conventional electrical radars, microwave photonic radars have demonstrated significant superiority in their perception and recognition capabilities. However, trade-offs exist among the reconfigurability, signal time-bandwidth product (TBWP), linearity, and phase coherence of current photonic radars, which ultimately weaken the overall performance. To address these challenges, a photonic transceiver based on electrically assisted synchronized lasers is proposed and demonstrated, which combines high resolution and multi-band reconfigurability.

Generation of tunable high-order vortex beams from a Hermite-Gaussian thin-disk laser.

We demonstrate the generation of high-order, high-power vortex modes from a Hermite-Gaussian (HG) Yb:YAG thin-disk oscillator, with tunable mode orders ranging continuously from one to ten. To the best of our knowledge, this is the highest order of HG and vortex modes obtained using a thin-disk module. The output power for most of these modes reaches up to 10 W, setting a new benchmark for intracavity high-order HG mode generation.

Integrated photonic MEMS switch for visible light.

Visible-light integrated photonics serve applications inaccessible to conventional (C- and O-band) silicon photonics, including trapped-ion and neutral atom quantum experiments, biophotonics, and displays. Despite demonstrations of increasingly advanced functionalities and levels of integration, the development of low-power, monolithically integrated, visible-light switches and phase shifters remains an outstanding challenge. Here, we demonstrate an integrated photonic, electrostatic MEMS-actuated Mach-Zehnder interferometer optical switch for the visible spectrum.

Fortunately, the data-driven approach based on deep learning has revolutionized the field.

Fiber transmission model with parameterized inputs based on generative pre-trained physics-informed neural networks.

In this manuscript, a principle-driven fiber transmission model for short-distance transmission with parameterized inputs is put forward. By taking into account the previously proposed principle-driven fiber model as the basic solution solver, the reduced basis expansion method and transforming the parameterized inputs into parameterized coefficients of the Nonlinear Schrödinger Equations, universal solutions with respect to inputs corresponding to different bit rates can all be obtained without the need of re-training the whole model. Once adopted, this model can have prominent advantages in both computation efficiency and physical background.

Numerical simulation and experimental validation of light modulation by laser-ablated ripples on fused silica surfaces.

Laser ablation is a commonly employed technique to enhance the damage resistance of fused silica optics due to its non-contact nature and the absence of polishing aids. However, during the ablation process, laser-induced ripples are inevitably formed, posing significant risks by potentially lowering the laser-induced damage threshold (LIDT). This study investigates the impact of these laser-ablated ripples on damage resistance using numerical models that account for electromagnetic fields, heat transfer, and solid mechanics.

Beyond 200 Gb/s/λ C-band PAM-4 low-latency transmission over 20-km nested antiresonant nodeless fiber.

The rapid growth of modern Internet applications demands ever-increasing transmission capacity and reduced latency in optical interconnect systems utilizing intensity modulation and direct detection (IM/DD). However, the intrinsic limitations of silica-based standard single-mode fiber (SMF) will ultimately be insufficient to meet these escalating demands. The nested antiresonant nodeless fiber (NANF), a newly designed hollow-core fiber, has garnered significant attention as a potential solution to these challenges.

Pinocembrin alleviates renal ischemia-reperfusion injury/unilateral ureteral obstruction (UUO)-generated renal fibrosis by targeting the CYP1B1/ROS/MAPK axis.

In our research, we constructed models of renal ischemia-reperfusion (I/R)-exposed acute kidney injury (AKI) and unilateral ureteral obstruction (UUO)-stimulated renal fibrosis (RF) in C57BL/6 mice and HK-2 cells. We firstly authenticated that oral pinocembrin (PIN) administration obviously mitigated tissue damage and renal dysfunction induced by I/R injury, and PIN attenuated UUO-caused RF, as confirmed by the reduced expression of fibrotic markers as well as hematoxylin-eosin (H&E), Sirius red, immunohistochemistry, and Masson staining. Meanwhile, the beneficial role of PIN was again demonstrated in HK-2 cells with hypoxia-reoxygenation (H/R) or transforming growth factor beta-1 (TGF-β1) treatment.

MHNet: Multi-view High-Order Network for Diagnosing Neurodevelopmental Disorders Using Resting-State fMRI.

Deep learning models have shown promise in diagnosing neurodevelopmental disorders (NDD) like ASD and ADHD. However, many models either use graph neural networks (GNN) to construct single-level brain functional networks (BFNs) or employ spatial convolution filtering for local information extraction from rs-fMRI data, often neglecting high-order features crucial for NDD classification. We introduce a Multi-view High-order Network (MHNet) to capture hierarchical and high-order features from multi-view BFNs derived from rs-fMRI data for NDD prediction.
