Mathematical modeling of cumulative implantation probability on the basis of published blastocyst euploidy rates across categories of female age.
The number of blastocysts required to achieve 95% cumulative implantation probability under the assumption of the absence of any other factor affecting implantation.
When the euploidy status of the transferred embryo is unknown (i.e., not subjected to preimplantation genetic testing for aneuploidies), our simulation shows that no age category reaches 95% cumulative probability of implantation of at least one embryo until after transfer of seven blastocysts. The number of blastocysts required to reach the same threshold is higher for older patients. For example, women older than 38 years require transfer of more than 10 unteecomes reasonably likely to be caused by factors other than embryo aneuploidy, the leading cause of implantation failure. We propose a new definition that factors in anticipated blastocyst euploidy rates across categories of female age, euploid blastocyst implantation rate, and a specified threshold of cumulative probability of implantation.The overhead contact system (OCS), as the power source of electrified railway, has a complex composition and various types of faults, so it places high requirements on its fault prevention. In recent years, with the establishment of railway OCS fault database, association analysis has been used to implement fault prevention from system-wise perspective and provide guidance for operation and maintenance. However, due to the hierarchical structure of fault database, the existing frequent itemset mining has a lot of redundancy in the results, and cannot locate the most precise faults, which affects the decision-making and makes troubleshooting lack of pertinence. To address this issue, this paper proposed a new concept, called marginal frequent itemset, which is an itemset composed of as precise items as possible in hierarchical database that meets the threshold, and an alternative mining task mining marginal frequent itemsets instead of all the frequent itemsets. selleckchem Two methods, path transform and descending depth of itemset, are proposed for achieving mining a set of marginal frequent itemsets. Two novel measures, margin degree and marginal information quantity, are proposed to evaluate the content of the mining results. An efficient algorithm, named MFIMCL, is developed for mining cross-level marginal frequent itemsets from railway OCS fault database. Our performance study shows that MFIMCL has high performance and can obtain more key information and reduce the number of results. Furthermore, marginal frequent itemset mining can simplify the fault relation network constructed by association rules and optimize the decision-making process for fault prevention of railway OCS.This paper suggests an experimental implementation study of the Wind Energy Conversion System (WECS) based on efficient Direct Power Control (DPC). Stand-alone mode for variable wind speed application using Doubly-Fed Induction Generator (DFIG) is studied and developed in this work. Due to the wind power performance limitation of traditional PI controllers, such as overshoot, response time, and static error; IP (integral-Proportional) controllers is replaced instead of the PI to control rotor current d-q components (Ird and Irq) in a Park frame through AC-DC-AC converter. A comparative experimental study was implemented to improve the power quality using L, LC & LCL passive filters between the DFIG's rotor circuit and the inverter. Experimental results prove that the proposed DPC under stand-alone mode with LCL-Type filter could operate in several conditions despite the sudden wind speed variations. It improves the unity power factor grid operation (≈0.98), dynamic responses, and the decoupled power control with high wind power performances good reference tracking, short response time, neglected overshoot, and low power error. The power quality injected into the RL-load satisfied the limit specified by IEEE harmonic standard 519 (less than 5%).Molybdenum is an important alloy element for metallurgical industry because of its high temperature stability. As the major mineral reserve for molybdenum, molybdenite (MoS2) is commonly found in porphyry copper deposits. Molybdenite is naturally floatable and can be separated from copper sulfide mineral using froth flotation. Properties of molybdenite such as mineralogy, microstructure, surface wettability, zeta potential, etc. can have a great effect on its floatability. Organic and inorganic depressants and surface pre-treatment methods are applied to improve the recovery of molybdenite. Electrochemical potential measurements using different electrodes are used to monitor process conditions and enable processing parameter adjustments to improve flotation circuit performance and reduce operating costs. Cations like Ca2+ and Mg2+ are reported to have negative effects on the flotation of molybdenite in alkaline solution, and dispersants and oil collectors need to be added to restore the flotation of molybdenite. In addition, effects of gangue minerals, particle size, and oil collectors and surfactants on molybdenite recovery are also discussed in this manuscript.
For-profit (FP) trauma centers (TCs) charge more for trauma care than not-for-profit (NFP) centers. We sought to determine charges, length of stay (LOS), and complications associations with TC ownership status (FP, NFP, and government) for three diagnoses among patients with overall low injury severity.
Adult patients treated at TCs with an International Classification of Diseases-based injury severity score (ICISS) survival probability≥0.85 were identified. Only those who with a principal diagnosis of femur, tibial or rib fractures were included.
Total charges were significantly higher at FP centers than NFP and lower at government centers (89.6% and-12.8%, respectively). FP TCs had a 12.5% longer LOS and government TCs had a 20.4% longer LOS than NFP TCs.
Patients presenting to FP TCs with mild/moderate femur, tibial, or rib fractures experienced higher charges and increased LOS compared with government or NFP centers. There was no difference in overall complication rates.

Women account for 19% of practicing surgeons in the United States, with representation decreasing with higher academic rank. Less is known about the proportion of women in editorial leadership positions at surgical journals. The objective of this study was to examine gender representation among editorial leadership at high-impact surgical journals.
The five journals with the highest impact factors in general, cardiothoracic, plastics, otolaryngology, orthopedics, urology, vascular, and neurosurgery were identified. Data were abstracted on the proportion of women editors-in-chief (EIC) and editorial board members between 2010 and 2020 to determine how these demographics changed over time.
Multiple fields had no women EIC over the past decade (orthopedics, urology, cardiothoracic, neurosurgery). In all other fields, women were a minority of EIC. In 2020, women made up 7.9% of EIC and 11.1% of editorial boards in surgical journals.
Women remain under-represented among leadership at high-impact surgical journals, with varying improvement over the past decade among different subspecialties.

Burnout, often regarded as an individual failing, rather than a systemic one, negatively impacts quality of care, patient safety and healthcare costs. Focusing on improving well-being can help mitigate burnout. This study examined protective factors that promote well-being and professional fulfillment in surgeons.
Using a purposive sample, 32 semi-structured 30-60-min interviews were conducted with surgeons of varying sub-specialties and rank. Abductive exploratory analysis was used to code and interpret interview transcripts and to build a conceptual model of surgeon well-being.
Emergent protective factors were placed into one of three levels of implementation individual, team-level, and institutional (figure). Individual factors for well-being included autonomy and adequate time to pursue non-clinical endeavors. Team-level factors consisted of adaptability, boundaries, and cohesion. Institutional factors related to diversifying performance evaluations and celebrating and recognizing individual value and contributions.
The conceptual model developed from the results of this study highlights factors important to surgeons' professional well-being. This model can be used to guide quality improvement efforts.

Effects of the institutional macrocosm on general surgery resident wellbeing have not been well studied. We sought to identify organizational factors that impact resident wellness and burnout.
Using a modified Delphi technique, an open-ended survey and two subsequent iterations were distributed to wellness stakeholders at two institutions to identify and stratify institutional factors in six burnout domains.
Response rates for each survey round were 29/106 (27%), 30/46 (65%) and 21/30 (70%). Top factors identified in each domain were CONCLUSION A modified Delphi technique prioritized institutional wellness and burnout factors. Top factors identified were compensation, vacation time, and autonomy. These results can direct future scholarship of barriers/facilitators of resident wellbeing.

The National Inpatient Sample (NIS) was queried between 2013 and 2018 for patients undergoing TMVR using the International Classification of Diseases (ICD) 9 procedure code '3597' and ICD-10 procedure code '02UG3JZ'. Patients undergoing TMVR were stratified into two groups, determined by hospital length of stay (LOS) [≤1 day, NDD versus >1-day, non-NDD]. Overall, 22,035 patients underwent TMVR with 35.7% (n = 7,870) belonging to the NDD group (mean age 78.1 ± 9.7 years, women 45%). From 2013 to 2018, the proportion of patients being discharged using the NDD approach trended upward from 18.3% to 46.0%. Amongst demographic and social factors, female sex, black race, and low median household income were predictive of non-NDD (p less then 0.
