SSBI counteraction technology in a single photodetector-based direct detection system receiving an independent dual-single sideband signal.

To further meet the large capacity, high spectrum efficiency (SE), reduce the signal-signal beat interference (SSBI) of the independent dual single sideband (ISB) system and the complexity of the receiver, we propose an iterative signal-signal beat interference counteraction (ISSBIC) algorithm to suppress SSBI. The 16-Gbps left sideband and the 16-Gbps right sideband signals in the ISB system are quadrature phase-shift keying (QPSK) modulated. After standard single-mode fiber (SSMF) transmission, the LSB and RSB signals are synthesized to a 16-quadrature amplitude modulation (QAM) signal after conversion through the photodetector (PD) square law.

Predicting anti-tumor efficacy of multi-functional nanomedicine on decellularized hepatocellular carcinoma-on-a-chip.

Traditional hepatocellular carcinoma-chip models lack the cell structure and microenvironments necessary for high pathophysiological correlation, leading to low accuracy in predicting drug efficacy and high production costs. This study proposed a decellularized hepatocellular carcinoma-on-a-chip model to screen anti-tumor nanomedicine. In this model, human hepatocellular carcinoma (HepG2) and human normal liver cells (L02) were co-cultured on a three-dimensional (3D) decellularized extracellular matrix (dECM) in vitro to mimic the tumor microenvironments of human hepatocellular carcinoma in vivo.

Chinese counseling trainees' trait and state mindfulness and client symptom outcome: A longitudinal examination with multilevel and random-intercept cross-lagged panel models.

This study aimed to explore how Chinese counseling trainees' trait and state mindfulness predicted their clients' symptom level over the course of therapy. A data set consisting of 6,888 sessions from 1,216 clients and their 211 master's level beginning therapist trainees in China was used, which included a measure of trainees' trait mindfulness at the beginning of their practicum and their state mindfulness and client-rated symptom distress level at the beginning of each of their therapy sessions. Multilevel modeling and random-intercept cross-lagged panel model results suggested that (a) at the trainee level, a trainee's trait mindfulness did not predict their average client symptom improvement over practicum; (b) at the session-to-session level, higher trainee state mindfulness before one session significantly predicted lower client distress before the next session, and higher client distress before one session did not predict trainee state mindfulness before the subsequent session.

Therapist self-efficacy developmental profiles, supervisory working alliance, and client outcome: A growth mixture analysis.

The aims of this study were to investigate the overall, and subgroups of, developmental profiles of the three domains of counseling self-efficacy (CSE) among beginning therapist trainees in China. Further, the associations between the different CSE developmental profiles and the trainees' perceived supervisory working alliance (SWA) and their clients' reported symptom distress were also examined. Participants included 258 beginning therapist trainees in a master's level counseling training program in China, who completed measures of CSE in three waves throughout the practicum and rated SWA after every supervision session.

Examining therapist estimation of client working alliance and client symptom outcome using truth and bias model and response surface analysis.

Objective: The aims of this study were to investigate the congruence and discrepancy between Chinese therapist trainees' estimated client working alliance (WA) and their clients' actual WA rating, and how the congruence and discrepancy predicted client symptom outcome.

Methods: Participants were 211 beginning therapist trainees and 1216 clients. Data from their 6888 sessions were analyzed using Truth and Bias Model and Response Surface Model.

The development of a Brief Working Alliance Inventory for clients and therapists using multilevel factor analysis and item response theory in the United States and China.

This study aimed to investigate the multilevel factor structure of the therapist and client versions of the 12-item Working Alliance Inventory-Short Revised (WAI; Hatcher & Gillaspy, 2006) in the United States and China, and to create a three-item brief version (WAI-B3) using multilevel factor analysis (M-FA) and multilevel item response theory (M-IRT). We gathered eight data sets from two samples each in United States and China with a total of 21,623 sessions from 376 therapists and 2,455 clients. M-FA results with the first four data sets (two American and two Chinese) suggested that the 12-item WAI across therapist and client versions, and in both United States and China showed a dominant general WA factor with three specific subgroup factors corresponding to the Goal, Task, and Bond items.

Creating a brief form of the Supervisory Working Alliance Inventory in the Chinese cultural context using multilevel factor analyses.

The aim of this study was to examine the multilevel factor structure of the Supervisory Working Alliance Inventory (SWAI; Efstation et al., 1990) and shorten it for routine clinical use in the Chinese cultural context. Participants were 203 (Sample 1) and 97 (Sample 2) beginning counseling trainees from a master's level training program in China.

The "roller coaster ride": A longitudinal investigation of the dynamic relationship between Chinese counseling trainees' self-efficacy and their clients' outcome and the mediating effects of working alliance and session evaluation.

[Correction Notice: An Erratum for this article was reported in Vol 69(4) of (see record 2022-76740-002). In the article, the scale for the Working Alliance Inventory-Short Revised (WAI-SR) was incorrectly described in the Measures section as a "5-point scale that ranges from 1 to 5." The WAI-SR used the original 7-point scale ranging from 1 to 7.

Exploring Therapist Self-Efficacy Change Profiles Using Latent Growth Curve Analysis.

Objective: This study investigated the overall developmental trajectories of three conceptually progressive aspects of counseling self-efficacy, including helping skills (HS), session management (SM), and counseling challenges (CH), among beginning therapist trainees in China.

Method: Participants included 103 beginning therapist trainees in a master's level counselor training programme in China, who filled out measures of counselor self-efficacy in three waves over one year of practicum.

Results: (a) Trainees showed highest initial level of HS, followed by SM, with CH being the lowest; and there were significant increases in all three aspects of self-efficacy.

Conductive Composite Fiber with Optimized Alignment Guides Neural Regeneration under Electrical Stimulation.

Conductivity and alignment of scaffolds are two primary factors influencing the efficacy of nerve repair. Herein, conductive composite fibers composed of poly(ɛ-caprolactone) (PCL) and carbon nanotubes (CNTs) with different orientation degrees are prepared by electrospinning at various rotational speeds (0, 500, 1000, and 2000 rpm), and meanwhile the synergistic promotion mechanism of aligned topography and electrical stimulation on neural regeneration is fully demonstrated. Under an optimized rotational speed of 1000 rpm, the electrospun PCL fiber exhibits orientated structure at macroscopic (mean deviation angle = 2.

Challenges and recommendations for mental health providers during the COVID-19 pandemic: the experience of China's First University-based mental health team.

Coronavirus Disease is impacting the entire world. As the first country that has needed to confront this disease, China has responded with unprecedented and hugely successful public health initiatives. Almost simultaneous with the awareness of the potential for widespread loss of life, the first Chinese university recognizing the likely psychological impacts of COVID-19, assembled the first university-based professional team to offer pandemic-related mental health services to the Chinese public.

The Cross-Cultural Loss Scale: development and psychometric evaluation.

The Cross-Cultural Loss Scale (CCLS), a measure of loss associated with crossing national boundaries, was developed across 2 samples of international students. With Sample 1 (N = 262), exploratory factor analyses were used to select the 14 CCLS items and to determine 3 factors: Belonging-Competency (α = .87), National Privileges (α = .

Profiles of acculturative adjustment patterns among Chinese international students.

This is the first study to empirically identify distinct acculturative adjustment patterns of new international students over their first 3 semesters in the United States. The sample consisted of 507 Chinese international students studying in the United States. Using psychological distress as an indicator of acculturative adjustment, measured over 4 time points (prearrival, first semester, second semester, and third semester), 4 distinct groups of student adjustment trajectories emerged: (a) a group exhibiting high levels of psychological distress across each time point (consistently distressed; 10%), (b) a group with decreasing psychological distress scores from Time 1 to Time 2 (relieved; 14%), (c), those with a sharp peak in psychological distress at Time 2 and Time 3 (culture-shocked; 11%), and (d) a group with relatively consistent low psychological distress scores (well-adjusted; 65%).
