Prevalence And Descriptive Epidemiology Of Choanal Atresia And Stenosis In Texas, 1999–2018, Renata H Benjamin, Lisa K Marengo, Angela E Scheuerle, A J Agopian, Laura E Mitchell

Faculty, Staff and Student Publications

Choanal atresia and stenosis are common causes of congenital nasal obstruction, but their epidemiology is poorly understood. Compared to bilateral choanal atresia/stenosis, unilateral choanal atresia/stenosis is generally diagnosed later and might be under-ascertained in birth defect registries. Data from the population-based Texas Birth Defects Registry and Texas vital records, 1999-2018, were used to assess the prevalence of choanal atresia/stenosis. Poisson regression models were used to evaluate associations with infant and maternal characteristics in two analytic groups: isolated choanal atresia/stenosis (n = 286) and isolated, bilateral choanal atresia/stenosis (n = 105). The overall prevalence of choanal atresia/stenosis was 0.92/10,000, and the …

Performance Analysis Of Hybrid Deep Learning Framework Using A Vision Transformer And Convolutional Neural Network For Handwritten Digit Recognition, Vanita Agrawal, Jayant Jagtap, Shruti Patil, Ketan Kotecha

Faculty, Staff and Student Publications

Digitization created a demand for highly efficient handwritten document recognition systems. A handwritten document consists of digits, text, symbols, diagrams, etc. Digits are an essential element of handwritten documents. Accurate recognition of handwritten digits is vital for effective communication and data analysis. Various researchers have attempted to address this issue with modern convolutional neural network (CNN) techniques. Even after training, CNN filter weights remain unchanged despite the high identification accuracy. As a result, the process cannot flexibly adapt to input changes. Hence computer vision researchers have recently become interested in Vision Transformers (ViTs) and Multilayer Perceptrons (MLPs). The shortcomings of …

The Unusual Substrate Specificity Of Escherichia Coli Cardiolipin Synthase C Does Not Require The Product Of The Transcriptionally Engaged Ymdb Gene, Katsuhiro Sawasato, Mikhail Bogdanov

Faculty, Staff and Student Publications

Polycistronic transcription and translation of ymdB-clsC have been thought to be required for full activity of ClsC. The authentic initiation codon of the clsC gene is present within the open reading frame of the upstream located ymdB gene. ClsC translated from authentic initiation codon drives cardiolipin (CL) synthesis without transcriptionally paired YmdB. YmdB is not necessary for the substrate specificity of ClsC utilizing phosphatidylethanolamine (PE) as a co-substrate.

Faculty, Staff and Student Publications

A putative glufosinate‐resistant Amaranthus palmeri population was reported in 2015 in Anson County, North Carolina. The results from dose–response assays conducted in the field suggested plants were surviving lethal rates of glufosinate. Dose–response assays conducted in the glasshouse determined the Anson County accession exhibited reduced susceptibility to glufosinate compared to three glufosinate‐susceptible populations. The LD50 values (210–316 g ai ha−1) for the Anson County population were always higher than the LD50 values (118–158 g ai ha−1) for the tested susceptible populations from the dose–response assays. Anson County plants that survived lethal glufosinate rates were reciprocally crossed with susceptible plants to …

Total Hip Arthroplasty With Subtrochanteric Osteotomy For Crowe Iv Dysplasia Using An Extensile Direct Anterior Approach: A Surgical Technique, Brian T Muffly, Erik M Hegeman, Braden E Hartline, Keerat Singh, Ajay Premkumar, George N Guild

Faculty, Staff and Student Publications

The direct anterior approach (DAA) has been increasing in popularity for primary total hip arthroplasty (THA). Despite previously documented anatomic limitations to its direct distal extension, alternative exposure methods have been described to safely access the femoral diaphysis and facilitate increasingly complex primary and revision THA scenarios. The DAA has several purported advantages compared to alternative approaches (eg, posterior and lateral-based), including its muscle-sparing nature, use of an internervous plane, and preservation of posterior stabilizing structures. Proponents of the DAA cite decreased postoperative pain, quicker recovery times, potentially lower dislocation rates, ease of intraoperative fluoroscopy, and improved implant placement/restoration of …
