Interpreting “Settled Abroad” in China’s Nationality Law: Theory, Practice, and Problems
The globalization of China and active international migration across Chinese borders involving millions of people have made understanding Chinese nationality law an issue of tremendous importance. In recent years, disputes concerning nationality have arisen out of undefined terms in the Nationality Law. At the center is the term “settled abroad,” which impacts the nationality of those who acquire foreign nationality and children born to overseas Chinese citizens. The limited literature and legislative interpretations do not clearly define the term. A thorough analysis shows that “settled abroad” means permanent or long-term residency and generally does not scrutinize the length of the actual residence period except for a complete absence of actual residence or undocumented migration. This Note further examines all publicly available cases disputing nationality in the past seven years to understand the judicial practice. It turns out Chinese courts also refrain from inquiring about the actual residence period in non-criminal cases. In recent years, the sensitive nature of the issue and the discoordination among authorities have prevented amendment or interpretation of the nationality law.
This Note makes two key contributions to the literature. First, it provides a much-needed interpretation of the key provisions in Nationality Law that have profound implications for millions of people. In contrast to prior literature, which often lacks sufficient comparison and analysis, this Note addresses all prior discussions in a comprehensive way. Second, it is the first work that applies empirical methods to examine how Chinese courts apply the Nationality Law. Finally, this Note also offers several explanations for the stagnant amendment of the Nationality Law from a policy angle
Multi-event Video-Text Retrieval
Video-Text Retrieval (VTR) is a crucial multi-modal task in an era of massive
video-text data on the Internet. A plethora of work characterized by using a
two-stream Vision-Language model architecture that learns a joint
representation of video-text pairs has become a prominent approach for the VTR
task. However, these models operate under the assumption of bijective
video-text correspondences and neglect a more practical scenario where video
content usually encompasses multiple events, while texts like user queries or
webpage metadata tend to be specific and correspond to single events. This
establishes a gap between the previous training objective and real-world
applications, leading to the potential performance degradation of earlier
models during inference. In this study, we introduce the Multi-event Video-Text
Retrieval (MeVTR) task, addressing scenarios in which each video contains
multiple different events, as a niche scenario of the conventional Video-Text
Retrieval Task. We present a simple model, Me-Retriever, which incorporates key
event video representation and a new MeVTR loss for the MeVTR task.
Comprehensive experiments show that this straightforward framework outperforms
other models in the Video-to-Text and Text-to-Video tasks, effectively
establishing a robust baseline for the MeVTR task. We believe this work serves
as a strong foundation for future studies. Code is available at

Structural Properties and Interaction Partners of Familial ALS-Associated SOD1 Mutants
Amyotrophic lateral sclerosis (ALS) is the most common motor neuron degenerative disease in adults and has also been proven to be a type of conformational disease associated with protein misfolding and dysfunction. To date, more than 150 distinct genes have been found to be associated with ALS, among which Superoxide Dismutase 1 (SOD1) is the first and the most extensively studied gene. It has been well-established that SOD1 mutants-mediated toxicity is caused by a gain-of-function rather than the loss of the detoxifying activity of SOD1. Compared with the clear autosomal dominant inheritance of SOD1 mutants in ALS, the potential toxic mechanisms of SOD1 mutants in motor neurons remain incompletely understood. A large body of evidence has shown that SOD1 mutants may adopt a complex profile of conformations and interact with a wide range of client proteins. Here, in this review, we summarize the fundamental conformational properties and the gained interaction partners of the soluble forms of the SOD1 mutants which have been published in the past decades. Our goal is to find clues to the possible internal links between structural and functional anomalies of SOD1 mutants, as well as the relationships between their exposed epitopes and interaction partners, in order to help reveal and determine potential diagnostic and therapeutic targets
Improving EFL Learners Language Written Production Using Subtitled Videos
English as a Foreign Language (EFL) Learners tend to produce their speech or written production as they are associated with what they see and what they hear. So, they are able and desired to give comment spontaneously after watching and listening to them. Producing written language can, as a matter of fact, be detected from learners\u27 fluency, accuracy and complexity. This article endeavors to elaborate written language production done by university students by using English subtitled videos. Two intact groups were assigned to accomplish two different tasks; that is, one group watched the video with subtitle and the other one without subtitle. The result of the study reveals that learners who carry out the tasks of watching video with subtitle improve their ability in written production in terms of fluency and accuracy regardless to complexity

Comparative structural analysis of Bru1 region homeologs in Saccharum spontaneum and S. officinarum
BACKGROUND: Sugarcane is a major sugar and biofuel crop, but genomic research and molecular breeding have lagged behind other major crops due to the complexity of auto-allopolyploid genomes. Sugarcane cultivars are frequently aneuploid with chromosome number ranging from 100 to 130, consisting of 70–80 % S. officinarum, 10–20 % S. spontaneum, and 10 % recombinants between these two species. Analysis of a genomic region in the progenitor autoploid genomes of sugarcane hybrid cultivars will reveal the nature and divergence of homologous chromosomes. RESULTS: To investigate the origin and evolution of haplotypes in the Bru1 genomic regions in sugarcane cultivars, we identified two BAC clones from S. spontaneum and four from S. officinarum and compared to seven haplotype sequences from sugarcane hybrid R570. The results clarified the origin of seven homologous haplotypes in R570, four haplotypes originated from S. officinarum, two from S. spontaneum and one recombinant.. Retrotransposon insertions and sequences variations among the homologous haplotypes sequence divergence ranged from 18.2 % to 60.5 % with an average of 33.7 %. Gene content and gene structure were relatively well conserved among the homologous haplotypes. Exon splitting occurred in haplotypes of the hybrid genome but not in its progenitor genomes. Tajima’s D analysis revealed that S. spontaneum hapotypes in the Bru1 genomic regions were under strong directional selection. Numerous inversions, deletions, insertions and translocations were found between haplotypes within each genome. CONCLUSIONS: This is the first comparison among haplotypes of a modern sugarcane hybrid and its two progenitors. Tajima’s D results emphasized the crucial role of this fungal disease resistance gene for enhancing the fitness of this species and indicating that the brown rust resistance gene in R570 is from S. spontaneum. Species-specific InDel, sequences similarity and phylogenetic analysis of homologous genes can be used for identifying the origin of S. spontaneum and S. officinarum haplotype in Saccharum hybrids. Comparison of exon splitting among the homologous haplotypes suggested that the genome rearrangements in Saccharum hybrids after hybridization. The combined minimum difference at 19.5 % among homologous chromosomes in S. officinarum would be sufficient for proper genome assembly of this autopolyploid genome. Retrotransposon insertions and sequences variations among the homologous haplotypes sequence divergence may allow sequencing and assembling the autopolyploid Saccharum genomes and the auto-allopolyploid hybrid genomes using whole genome shotgun sequencing.

Genome-wide analysis of the GRAS gene family in Liriodendron chinense reveals the putative function in abiotic stress and plant development
IntroductionGRAS genes encode plant-specific transcription factors that play essential roles in plant growth and development. However, the members and the function of the GRAS gene family have not been reported in Liriodendron chinense. L. chinense, a tree species in the Magnolia family that produces excellent timber for daily life and industry. In addition, it is a good relict species for plant evolution research.MethodsTherefore, we conducted a genome-wide study of the LcGRAS gene family and identified 49 LcGRAS genes in L. chinense.ResultsWe found that LcGRAS could be divided into 13 sub-groups, among which there is a unique branch named HAM-t. We carried out RNA sequencing analysis of the somatic embryos from L. chinense and found that LcGRAS genes are mainly expressed after heart-stage embryo development, suggesting that LcGRAS may have a function during somatic embryogenesis. We also investigated whether GRAS genes are responsive to stress by carrying out RNA sequencing (RNA-seq) analysis, and we found that the genes in the PAT subfamily were activated upon stress treatment, suggesting that these genes may help plants survive stressful environments. We found that PIF was downregulated and COR was upregulated after the transient overexpression of PATs, suggesting that PAT may be upstream regulators of cold stress. DiscussionCollectively, LcGRAS genes are conserved and play essential roles in plant development and adaptation to abiotic stress
