    Abstract Open radio access network (ORAN) provides an open architecture to implement radio access network (RAN) of the fifth generation (5G) and beyond mobile communications. As a key technology for the evolution to the sixth generation (6G) systems, cell-free massive multiple-input multiple-output (CF-mMIMO) can effectively improve the spectrum efficiency, peak rate and reliability of wireless communication systems. Starting from scalable implementation of CF-mMIMO, we study a cell-free RAN (CF-RAN) under the ORAN architecture. Through theoretical analysis and numerical simulation, we investigate the uplink and downlink spectral efficiencies of CF-mMIMO with the new architecture. We then discuss the implementation issues of CF-RAN under ORAN architecture, including time-frequency synchronization and over-the-air reciprocity calibration, low layer splitting, deployment of ORAN radio units (O-RU), artificial intelligent based user associations. Finally, we present some representative experimental results for the uplink distributed reception and downlink coherent joint transmission of CF-RAN with commercial off-the-shelf O-RUs.

    Abstract Expansions of short nucleotide repeats account for more than 50 neurological or neuromuscular diseases. Many repeat expansion-containing RNAs can generate toxic repeat proteins through repeat-associated non-AUG (RAN) translation in all the reading frames. Understanding how RAN translation occurs and what cellular factors regulate this process will help decipher the basic mechanism of the molecular process and disease pathogenesis. Using reporter systems to quantitatively measure RAN translation provides a platform to examine candidate genes/pathways and screen for modifiers of this non-canonical pathway. In this chapter, we describe the dual-luciferase reporter system to measure RAN translation using C9ORF72 GGGGCC

    Abstract The evolution of network technologies has witnessed a paradigm shift toward open and intelligent networks, with the Open Radio Access Network (O-RAN) architecture emerging as a promising solution. O-RAN introduces disaggregation and virtualization, enabling network operators to deploy multi-vendor and interoperable solutions. However, managing and automating the complex O-RAN ecosystem presents numerous challenges. To address this, machine learning (ML) techniques have gained considerable attention in recent years, offering promising avenues for network automation in O-RAN. This paper presents a comprehensive survey of the current research efforts on network automation usingML in O-RAN.We begin by providing an overview of the O-RAN architecture and its key components, highlighting the need for automation. Subsequently, we delve into O-RAN support forML techniques. The survey then explores challenges in network automation usingML within the O-RAN environment, followed by the existing research studies discussing application of ML algorithms and frameworks for network automation in O-RAN. The survey further discusses the research opportunities by identifying important aspects whereML techniques can benefit.

    Abstract Background: Lymph node metastasis is a key mechanism in gastric cancer (GC) metastasis and lymphangiogenesis is a vital step in the process of lymph node metastasis. Currently, there are no drugs which can treat lymph node metastasis in GC. Previous studies using the drug fucoxanthin have mainly focused on cell cycle arrest, induction of apoptosis, or inhibition of angiogenesis in GC. However, the effects of fucoxanthin on lymphangiogenesis and metastasis in GC have not been studied.
    Methods: Cell counting kit 8 and transwell experiments were used to evaluate the inhibitory effect of fucoxanthin on cell proliferation, migration and invasion. HGC-27 and HLEC cells were co-cultured in a transwell chamber and the footpad metastasis model was established to evaluate lymphangiogenesis and lymph node metastasis. The possible regulatory targets of fucoxanthin in GC were analyzed using human tissue microarrays, bioinformatics analysis, and molecular docking. The regulatory pathway of fucoxanthin was verified using confocal laser microscopy, adenovirus transfection and western blotting.
    Results: Tissue microarray and bioinformatics analyses showed that Ran was highly expressed in metastatic lymph nodes and has some predictive value for metastasis in GC. Molecular docking results revealed that fucoxanthin interacted with Met189 and Lys167 of Ran via hydrogen bonds. Mechanistically, fucoxanthin inhibits the nuclear transport of NF-κB by downregulating protein expression of Ran and importinβ, thereby inhibiting VEGF-C secretion, and ultimately inhibiting tumor lymphangiogenesis and lymph node metastasis in vivo and in vitro.
    Conclusions: Fucoxanthin suppressed GC-induced lymphangiogenesis and metastasis in vitro and in vivo by regulating Ran expression via the importinβ/NF-κB/VEGF-C nuclear transport signaling pathway. These novel findings provide the basis for the research and development of novel treatments using traditional Chinese medicine in treatment of lymph node metastasis, which has important theoretical significance and clinical value.

    Abstract The present study investigated how phonological awareness and rapid automatized naming (hereafter, RAN), simultaneously contributed to Chinese reading and arithmetic fluency. Specifically, we proposed a new hypothesized mechanism that processing speed would mediate the relations of RAN with Chinese reading and arithmetic fluency. One hundred and forty-five Chinese children at the fifth grade were administered with a battery of measures, including three phonological processing measures, character reading, and whole number computation, as well as nonverbal IQ, and vocabulary knowledge. Path analyses revealed that phonological awareness and RAN were uniquely related to character reading and arithmetic fluency, while phonological memory was not significantly correlated to either character reading or arithmetic fluency, after controlling for age, nonverbal IQ, and vocabulary knowledge. Further analysis indicated that processing speed demonstrated a mediating effect on the importance of RAN in character reading, rather than in arithmetic fluency. Results underscore the potential importance of phonological awareness and RAN in character reading and arithmetic fluency, and the mediating role of processing speed in RAN to promote Chinese character reading fluency.

    Abstract Background: Hepatocellular carcinoma (HCC) is a common malignant tumor with high mortality. The prognostic significance of Ran, a member of Ras superfamily, remains unclear in HCC patients.
    Methods: Based on The Cancer Genome Atlas (TCGA) database and Tumor Immune Estimation Resource (TIMER), we analyzed the correlations among Ran expression, promoter methylation and immune cell infiltration. We also investigated the Ran expression levels in HCC tissues and normal tissues by using quantitative real-time PCR.
    Results: Ran mRNA expression was significantly increased in HCC tissues compared with the normal tissues (P < 0.001). Time-dependent receiver operating characteristic (ROC) curves showed that Ran expression had predictive value of the 1-, 3- and 5-year overall survival for HCC patients, and the areas under the curves (AUC) were 0.747, 0.634 and 0.704, respectively. Cox regression analysis showed that Ran expression was an independent prognostic factor for HCC patients (HR = 1.492, 95% CI: 1.129-1.971, P = 0.005). We also found a negative relationship between Ran mRNA expression and its promoter methylation (r = -0.36, P < 0.001). High Ran expression and promoter hypomethylation predicted worse overall survival and progression-free survival (P < 0.05) and were involved in the progression of HCC. Ran expression exhibited significant correlations with immune infiltrates and prognostic immune-related genes.
    Conclusions: The present study provides further insight into the prognosis of HCC, and Ran could serve as a biomarker for predicting the survival of HCC patients.

    Abstract Deformable image registration, the estimation of the spatial transformation between different images, is an important task in medical imaging. Deep learning techniques have been shown to perform 3D image registration efficiently. However, current registration strategies often only focus on the deformation smoothness, which leads to the ignorance of complicated motion patterns (e.g., separate or sliding motions), especially for the intersection of organs. Thus, the performance when dealing with the discontinuous motions of multiple nearby objects is limited, causing undesired predictive outcomes in clinical usage, such as misidentification and mislocalization of lesions or other abnormalities. Consequently, we proposed a novel registration method to address this issue: a new Motion Separable backbone is exploited to capture the separate motion, with a theoretical analysis of the upper bound of the motions' discontinuity provided. In addition, a novel Residual Aligner module was used to disentangle and refine the predicted motions across the multiple neighboring objects/organs. We evaluate our method, Residual Aligner-based Network (RAN), on abdominal Computed Tomography (CT) scans and it has shown to achieve one of the most accurate unsupervised inter-subject registration for the 9 organs, with the highest-ranked registration of the veins (Dice Similarity Coefficient (%)/Average surface distance (mm): 62%/4.9mm for the vena cava and 34%/7.9mm for the portal and splenic vein), with a smaller model structure and less computation compared to state-of-the-art methods. Furthermore, when applied to lung CT, the RAN achieves comparable results to the best-ranked networks (94%/3.0mm), also with fewer parameters and less computation.
