Optical single-sideband (SSB) transmission enhances spectral efficiency and mitigates transmission reach limitations caused by chromatic dispersion (CD), making it ideal for cost-effective data-center interconnects. This paper proposes and demonstrates deep neural network (DNN)-enabled optical performance monitoring (OPM) for optical SSB transmissions. By extracting features dependent on both carrier-to-signal power ratio (CSPR) and optical signal-to-noise ratio (OSNR) from amplitude histograms (AHs) generated by an AC-coupled photodetector (PD) and an analog-to-digital converter (ADC), a low-complexity dual-task DNN (DT-DNN) is employed to jointly estimate CSPR and OSNR with high accuracy.

Polarization engineering has revolutionized the photonic and electronic landscape of III-nitride semiconductors over the past decades. However, recent revelations of giant ferroelectric polarization in wurtzite III-nitrides challenge the long-standing paradigms. Here, we experimentally elucidate the polarization, including its magnitude and orientation, and its relationship to lattice polarity in III-nitrides.

Introduction And Hypothesis: The purpose of this study was to develop a maternal health care exercise and pelvic abdominal rehabilitation curriculum for obstetric medical professionals. Maternal health care exercise and pelvic abdominal rehabilitation can effectively prevent and alleviate pelvic-floor-rehabilitation problems in pregnant women and improve their quality of life. However, there is a lack of standardized courses for training obstetric medical professionals.

To understand the factors that preserve mental health amongst a diverse population of adolescents, we examined links between neighborhood-level resources, adolescents' self-reported personal assets (low perceived stress, meaning and purpose, life satisfaction), parent-reported family assets (household income, maternal mental health) and adolescents' self-reported depressive and anxiety symptoms. Participants included a racially and ethnically diverse national sample of 4325 adolescents (10 - 21 years) from the Environmental influences on Child Health Outcomes (ECHO) program. Neighborhood-level resources were not directly associated with depressive or anxiety symptoms.

Objective: Vitamin D(VitD) deficiency has been found prevalent among patients with thyroid autoimmunity (TAI). This study aimed to investigate whether low VitD2 or VitD3 potentially contributed to the development of TAI in euthyroid male patients, which had not been reported before.

Methods: A total of 2882 euthyroid male petroleum workers were recruited from those participants in the healthcare program at the second affiliated hospital of Dalian Medical University in 2021, whose serum VitD levels, thyroid functions, and autoantibody titers were all examined at the same time.

AlGaN-based ultraviolet (UV) light-emitting diodes (LEDs) experience a notable reduction in efficiency within the 280-330 nm wavelength range, known as the "UVB gap". Given the extensive applications of UV LEDs in this wavelength range, it is imperative to bridge this efficiency gap. In this study, a strategy facilitated by the presence of residual Al adatoms is introduced to simultaneously improve the integration of Ga-adatoms and the migration of Al/Ga-adatoms during the growth of low-Al-composition AlGaN quantum wells (QWs) even at high temperatures comparable to those used for high-Al-composition AlGaN quantum barriers.

Background: Polycystic ovary syndrome (PCOS) is a common complication of autoimmune thyroiditis (AIT) in women, but the underlying mechanism remains unclear. Protein disulfide isomerase A3 (PDIA3) is a ubiquitous protein. We have reported that PDIA3 autoantibody (PDIA3Ab) production results from autoimmune responses against thyrocytes, resulting in its high expression in euthyroid AIT patients.

Article Synopsis
  • T cell receptors (TCRs) are specific markers on T cells that help them recognize and bind to foreign antigens, playing a crucial role in immune responses.
  • TCRs rely on the CD3 molecule for proper signaling and structural stability, forming a TCR-CD3 complex that is essential for T cell activation.
  • Research on CD3 subunits' roles can enhance our understanding of immune system diseases and lead to new targeted therapies.

Background: The contribution of cholinergic degeneration to gait disturbance in Parkinson's disease (PD) is increasingly recognized, yet its relationship with dopaminergic-resistant gait parameters has been poorly investigated. We investigated the association between comprehensive gait parameters and cholinergic nucleus degeneration in PD.

Methods: This cross-sectional study enrolled 84 PD patients and 69 controls.

  • This study compares a new laparoscopic technique for para-aortic lymphadenectomy, called the "tent-pitching" antegrade approach, to the traditional retrograde approach in gynecological cancer surgeries, assessing success rates, complications, and lymph node counts.
  • A retrospective review of 173 patients revealed that the antegrade method had higher success rates (97.5% vs. 68.82%), removed more lymph nodes (median of 14 vs. 7), and had fewer complications compared to the retrograde method.
  • Anatomical variations in the para-aortic region were noted in nearly 29% of patients, helping to highlight the importance of understanding vascular anatomy for surgical safety.

Article Synopsis
  • Coal fines in propped fractures reduce the flow of gas and water, hurting coal seam permeability and gas production.
  • A new coal fine plugging removal agent composed of SDS, NaCl, and BS-12 was developed, showing high efficiency in removing coal fines and enhancing permeability.
  • By increasing the injection rate and using multiple cycles of the removal agent, over 90% of coal fines can be discharged, significantly boosting gas-liquid permeability within the fractures.

During the development of deep coalbed methane (CBM), the production of coal fines is common and suppresses the yield of CBM. This work takes the deep CBM wells in the Qinshui Basin as a case study, and the output, composition, morphology, and sources of coal fines were investigated through scanning electron microscopy, X-ray diffraction, proximate analysis, and particle size measurement including image analysis, laser diffraction, and dynamic light scattering. The results indicate that, in comparison with shallow CBM wells, deep wells produce a greater quantity of coal fines which are darker in color and have smaller particle sizes, with the majority being less than 10 μm.

The key to the variation in permeability within coal reservoirs lies in the stress-induced deformation and desorption-induced deformation during the coalbed methane (CBM) production. The differences in sample scale and measurement methods between stress-induced deformation and desorption-induced deformation significantly affect the accuracy of permeability measurements. Therefore, in order to elucidate the relationship between stress-induced deformation and adsorption-induced deformation, as well as the influencing factors, and to assess the accuracy of permeability evolution prediction, this study conducted a series of parallel experiments, including compression deformation experiments under stress loading (stress-induced deformation), methane adsorption-induced deformation experiments (adsorption-induced deformation), μCT scanning, and overburden permeability measurements.

  • Sensor-based gait analysis was used to study how anxiety affects walking in patients with Parkinson's disease (PD), revealing that anxiety can interfere with gait significantly.
  • A total of 144 PD patients were compared, with those having anxiety showing shorter strides and slower walking speed, particularly when not multitasking.
  • The research emphasized that anxiety notably worsens certain gait parameters, suggesting that addressing anxiety could improve treatment results for PD patients.

The current study (a) examined ethnic differences in mothers' and children's responses to children's performance in a challenging task, (b) tested the associations among children's desire for assistance, maternal control, and children's emotional responses to the challenge, and (c) explored whether these associations held across three ethnicities-Asian Americans (AA), Latinx Americans (LA), and European Americans (EA). Results showed that children's emotional arousal significantly increased and emotional valence became significantly less positive over the course of children experiencing repeated challenges in front of their mothers. In terms of ethnic differences, LA mothers exhibited more control than EA mothers, but LA children responded less negatively to the challenging task than EA children.
