A New Interpolated Pseudodifferential Preconditioner For The Helmholtz Equation In Heterogeneous Media

Faculty, Staff and Students Publications

This paper introduces a new pseudodifferential preconditioner for the Helmholtz equation in variable media with absorption. The pseudodifferential operator is associated with the multiplicative inverse to the symbol of the Helmholtz operator. This approach is well suited for the intermediate and high-frequency regimes. The main novel idea for the fast evaluation of the preconditioner is to interpolate its symbol, not as a function of the (high-dimensional) phase-space variables, but as a function of the wave speed itself. Since the wave speed is a real-valued function, this approach allows us to interpolate in a univariate setting even when the original problem …

A Case Of Igg4-Related Disease Manifesting As Extensive Abdominal Periarteritis And Membranous Nephropathy, Successfully Controlled With Low-Dose Steroid Therapy Without Relapse Or Complications, Minami Matsumoto, Shinya Yamamoto, Hideki Yokoi, Sho Koyasu, Shigeo Hara, Takahiro Tsuji, Minamiguchi Sachiko, Motoko Yanagita

Faculty, Staff and Students Publications

Introduction: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease that can affect nearly every organ system, including blood vessels and the kidney. IgG4-related vascular lesions mainly involve the aorta, and the dominant renal manifestation is tubulointerstitial nephritis (TIN). Here, we report a case of IgG4-RD demonstrating extensive abdominal periarteritis and membranous nephropathy (MN).

Case presentation: The patient was a 71-year-old man with peptic ulcer who developed nephrotic syndrome, with a low serum albumin level (1.8 g/dL), massive urinary protein (6.1 g/day), and high serum IgG4 level (435 mg/dL). Computed tomography images revealed soft tissue mass around the medium-sized abdominal arteries. …

Membranoproliferative Glomerulonephritis With Striated Ultrastructural Deposits With Significantly Elevated Fibrinogen And Fibronectin On Mass Spectrometry Analysis: A Case Report And Literature Review, Manna Ishida, Shinya Yamamoto, Yohei Iwashige, Shuma Miyazawa, Hirosuke Nakata, Koichi Seta, Kensei Yahata, Sachiko Minamiguchi, Yoko Endo, Akiko Mii, Akira Shimizu, Motoko Yanagita

Glomerular diseases with organized deposits can be classified into various etiologies. A diagnostic algorithm based on clinical and pathological findings has been proposed. However, some cases cannot be diagnosed using existing algorithms. Here, we report the case of a 77-year-old man diagnosed with membranoproliferative glomerulonephritis (MPGN) with striated ultrastructural deposits, micro-filament-like substructures with straight bands arranged in parallel in the subendothelial space by two sequential renal biopsies. His examinations and clinical findings were incompatible with known glomerular diseases with organized deposits. Dialysis was initiated 10 months after the second biopsy procedure. Furthermore, we report the first mass spectrometry analysis of …

The Constitution And The War On Dei, Sonja A. Starr, Genevieve Lakier

Public Law and Legal Theory Working Papers

his Article examines how the second Trump Administration’s aggressive attacks on programs, policies, and speech loosely associated with diversity, equity, and inclusion [DEI] intersect with the constitutional guarantees of equal protection and freedom of speech. We argue first that there is little doctrinal support for the administration’s pervasive efforts to justify its war on DEI by invoking the Equal Protection Clause and parallel statutory law. Instead, the administration is stretching existing colorblindness doctrine beyond recognition, into a radical vision that we label “anti-antisubordination.” On this view, vindicating equality values does not only require restricting practices that treat individuals differently based …

Defining Dysphoric Milk Ejection Reflex: Using Premenstrual Dysphoric Disorder As A Framework For Proposing Preliminary Diagnostic Criteria

Faculty, Staff and Students Publications

Dysphoric Milk Ejection Reflex (D-MER) is a distinct neurobiological condition characterized by negative alterations in mental state in response to milk letdown during lactation. Symptoms vary by patient and can include feelings of sadness, anxiety or agitation. Importantly, the symptoms are brief, typically lasting no more than 5 minutes. Prevalence has been found between 6 and 27% of lactating women, but studies show heterogeneity, due in part to inconsistent definition. D-MER is not currently classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD), which presents a challenge for researchers of the …

Increasing Surgical Healthcare Utilization For Infants With Congenital Anomalies In Texas, Kathleen Hosek, Dailen Alonso, Timothy C Lee, Sundeep G Keswani, Alice King

Faculty, Staff and Students Publications

Introduction: Congenital anomalies (CAs) impact 3% of live births and account for disproportionately high healthcare costs. While many CAs require multidisciplinary care and surgical intervention, the overall financial impact of infants diagnosed with CA with surgical needs is unknown. We aim to evaluate and characterize the charges of care in infants with CA and surgical needs in Texas.

Methods: A database study using the Texas Inpatient Public Use Data File was performed to query infants (< 365 days) statewide from 1/2021 to 12/2021 for admissions with CA and involved organ system by ICD-10 codes. Encounters transferred to an outside hospital were excluded to avoid systematic double-counting. Descriptive statistics were performed.

Results: Of 376,215 total admissions, 81,666 had surgical needs with OR charges. While non-CA represent the majority of surgical admissions (63,895/81,666; 78.24%), CA-surgical admissions …

Two-Dimensional Speckle Tracking Of The Ascending Aorta: A Novel Approach To Evaluate Arterial Stiffness In Pediatric Patients With Repaired Conotruncal Anomalies Using Echocardiography, Daniel Forsha, Doaa Aly

Faculty, Staff and Students Publications

Background: Children with repaired conotruncal abnormalities (CTA) are at risk of progressive aortic dilation and deteriorating aortic elasticity even after surgical correction. Strain imaging, using a 2-dimensional speckle tracking echocardiography (2D-STE), has been used for arterial stiffness assessment, but pediatric data are still lacking. We investigated the feasibility, reproducibility, and clinical value of 2D-STE derived ascending aorta (AAo) stiffness in children with repaired CTA.

Methods: 22 pediatric patients with repaired CTA were included along with 25 age- and sex- matched healthy controls (mean age 10.2 ± 4.5 years). Conventional 2D echocardiographic and 2D-STE assessment of AAo mechanics was performed. M-mode …
