On-chip spatial mode operation, represented as mode-division multiplexing (MDM), can support high-capacity data communications and promise superior performance in various systems numerous applications from optical sensing to nonlinear quantum optics. However, the scalability of state-of-the-art manipulation techniques is significantly hindered not only by particular mode-order-oriented design strategy but also inherent limitations possibly achievable orders. Recently, metamaterials capable...

Having to adapt a new environment with various other challenges while completing their studies, Chinese college students experience intense stress related the study of English language. However, there has been little research on serial mediating mechanism English-learning academic performance.

Introduction Parenting and peer victimization (PV) are crucial for adolescent drinking. To further explore the cause of drinking, present study investigated role PV personal growth initiative (PGI) in relationship between parental corporal punishment (PCP) Methods Present build moderated mediation models to test hypothesis, detailed analysis gender differences was conducted on models. The data were collected a cross-sectional questionnaire with n = 1,007 adolescents (mean age 13.16 years,...

Social media user geolocation is to infer users' resident locations based on social data, including texts and relationships. Existing methods mainly rely the textual feature propagation in graph fuse information. The accuracy susceptible insufficient data sources inadequate fusion. In this paper, a algorithm cyclic coupling (called UGCC) proposed. We collapse neighbor location proximity, which reduces noisy information while enriching Unlike existing that ignore graph's structure, UGCC...

The present study expands on previous research regarding the correlation between parental overprotection (POP) and non-suicidal self-injury (NSSI) in Chinese adolescents. Drawing from self-determination theory, aims to investigate mediating effect of psychological need satisfaction relationship POP adolescent NSSI, as well potential moderating anger expression. A sample 1248 adolescents (Mage = 13.34 years; SD 0.96 years) completed anonymous questionnaires measure variables. results...

Vital node discovery is a hotspot in network topology research. The key using the Internet's routing characteristics to remove noisy paths and accurately describe topology. In this manuscript, vital regional nodes algorithm based on proposed. We analyze stability of multiple rounds measurement results overcome single vantage point's path deviation. unstable are eliminated from which constructed through probing for target area, pruned more line with real rules. Finally, we weight edge actual...

Abstract This paper presents a real‐time OFDM‐based visible light communication (VLC) system utilizing single InGaN/GaN multiquantum‐wells (MQWs) emitting diode (LED). An MQWs LED with 3 dB electrical bandwidth of 23.8 MHz is developed as the transmitting device. Orthogonal frequency division multiplexing (OFDM) employed to ensure fully used, and designed implemented on field‐programmable gate array platform realize communication. The OFDM‐VLC achieves rate 96 Mbit/s at distance 2 m, bit...

Internet addiction (IA) is a growing social problem with negative mental and outcomes; the present study examined whether rejection sensitivity mediates relationship between interparental conflict adolescent IA moderating role of school connectedness. One thousand seven adolescents (51.84% females; Mean age = 13.17; SD 0.69) anonymously completed questionnaires to assess conflict, connectedness, sensitivity, IA, demographic information. The model results showed that: (1) positive association...

Existing city-level boundary nodes identification methods need to locate all IP addresses on the path differentiate which is node.However, these are susceptible time-delay, accuracy of location information and other factors, resource consumption locating IPes tremendous.To improve recognition rate reduce cost, this paper proposes an algorithm for node based bidirectional approaching.Different from existing time-delay results, proposed uses topological analysis construct a set candidate then...

Cyber-victimization is linked to various clinical outcomes, especially anxiety, depression, suicidal ideation, and non-suicidal self-injury. Despite these associations, the underlying mechanisms remain unclear. This study aimed test potential transdiagostic mediating role of interpersonal needs (tested by Interpersonal Needs Questionnaire, INQ) between cyber-victimization as well identify most influential need items. Using two-wave data from 1402 Chinese 7th 8th graders (Mage = 13.28 ± 0.72;...

Abstract Nonsuicidal self-injury (NSSI) is a global health concern. Parental corporal punishment shown to be related NSSI, with unclear underlying mechanisms. The current study tested potential mediator (i.e., depressive symptoms) and moderator the GABRA2 rs279858 genotype) in relationship between parental NSSI. Chinese adolescents ( N = 673; 53% girls; aged 11–14 years) completed self-report measures provided saliva samples for DNA genotyping. A moderated mediation model was tested. results...
