In bearings defect diagnosis applications, information fusion has been widely used to improve identification accuracy for different types of faults, which may lead to high-dimensionality and information redundancy of the data and thus degenerate the classification performance. Therefore, it is a major challenge for machinery fault diagnosis to extract optimal features from high-dimensional and redundant data for classification. In addition, in order to guarantee the performance of fault diagnosis, conventional supervised methods usually require a large amount of labeled data available for learning. However, it is extremely difficult, costly and time-consuming to collect faulty labeled samples with class information, especially for expensive and critical machines, which often results in only a few labeled data available with a large amount of unlabeled data redundant. In this paper, we propose a novel bearing defect diagnosis model based on semi-supervised kernel local Fisher Discriminant Analysis (SSKLFDA) usodel achieves higher classification performance than other existing dimensionality reduction methods-based models.

To study whether the growth trajectory of the first, second, and third trimester, birth, and 5 years of age differs between children born following fresh embryo transfer (fresh ET), frozen-thawed embryo transfer (FET), and children born after natural conception (NC).

Historical cohort study of children. The analysis compared cross-sectional and longitudinal differences in measurement between individuals stratified by method of conception.

Not applicable.

Participants were born between 1997 and 2012 by NC (n = 65,683), fresh ET (n = 576), and FET (n = 179). Data were available for method of conception and fetal, maternal, and neonatal characteristics and measurements at 5 years.

None MAIN OUTCOME MEASURE(S) Size at first, second, and third trimester, birth, and 5 years.

In the longitudinal model, first trimester crown-rump length was significantly longer after fresh ET compared to NC. Second trimester head size was larger after fresh ET and after FET compared to NC. Birth weight was lower after fresh ET conception compared to FET. At 5 years of age, children conceived by fresh ET and FET were no heavier than peers conceived by NC.

Individuals conceived by invitro fertilization have significantly different antenatal growth trajectories during the first and second trimester compared to those conceived by NC, and differences persist at birth for weight and head size. The relevance of these different growth trajectories remains uncertain, and larger prospective studies are required.

Individuals conceived by in vitro fertilization have significantly different antenatal growth trajectories during the first and second trimester compared to those conceived by NC, and differences persist at birth for weight and head size. The relevance of these different growth trajectories remains uncertain, and larger prospective studies are required.

To describe the treatments of a patient using the laparoscopic Davydov’s method for Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and ureteral reimplantation for hydronephrosis and hydroureter.

Surgical video article. A consent form from the patient was obtained as appropriate; the nature of the study did not necessitate ethics committee approval. There were no conflicts of interest.

A 28-year-old woman who presented at our gynecology department with the symptoms of primary amenorrhea and difficult intercourse. She had repaired congenital rectovestibular fistula and imperforate anus at the age of 8. At physical examination, she had a phenotypically normal vulva with a vaginal small pouch (0.5 cm). Magnetic resonance imaging of the pelvis revealed normal ovaries, a primordial uterus, absence of vaginal canal, and a 4.0 × 4.2 × 4.0 cm cystic structure posterior to the bladder. Magnetic resonance urography showed right to left renal crossed-ectopia with inferior fusion, and hydronepof the combined urogenital-Wolffian anomalies are reported; most of them are associated with the anomalies of müllerian duct fusion, such as Herlyn-Werner-Wunderlich syndrome (uterus didelphys, obstructed hemivagina, and mesonephric duct anomalies). The embryogenesis of the combined anomalies is not completely understood. With comprehensive preoperative assessments, laparoscopic surgery could be a safe and effective treatment to these cases.

To examine whether Society for Assisted Reproductive Technology (SART) member invitro fertilization (IVF) centers adhere to the Society’s new advertising policy, updated in January 2018, and evaluate other services advertised by region, insurance mandate and university affiliation status. Historically, a large percentage of IVF clinics have not adhered to SART guidelines for IVF clinic website advertising and have had variability in how financial incentives and other noncore fertility services are advertised.

Cross-sectional study.

Not applicable.

None.

None.

Adherence of SART participating websites to objective criteria from the 2018 SART advertising guidelines.

All 361 SART participating clinic websites were evaluated. Approximately one third of clinics reported success rate statistics directly on their websites, but only 52.6% of those clinics reported current statistics. Similarly, only 67.5% of SART member clinics included the required disclaimer statement regarding their outcome statistics. Only 10.5% of websites were wholly compliant with SART guidelines regarding presentation of supplemental data. There were no significant differences between academic and nonacademic centers, programs in mandated versus nonmandated states, or East versus West Coast clinics in any of these areas.

Many of the SART member websites failed to adhere to core guidelines surrounding reporting IVF clinic success rates. Consideration for additional education and streamlining as well as simplifying success rate advertising guidelines is recommended.
