Local urbanization impacts sandy beach macrofauna communities over time

Frontiers in Marine Science, 2023
Sandy beaches are ecologically important, physically dynamic, and heterogeneous habitats intrinsically related to human culture. However, these interactions present challenges for sandy beaches in the Anthropocene as stressors from urbanization increase.

Brownian local times

Advances in Mathematics, 1975
AbstractThe purpose of this paper is to present in a more or less self-contained way the chief facts about the local times t of one-dimensional Brownian motion due to P. Lévy, F. Knight, D. B. Ray, and Itô-McKean. The deepest part concerns the remarkable fact that for a class of stopping times m, such as passage times and independent exponential ...

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Excursion Laplace Exponents Under Height Truncation

Mathematics
We study one-dimensional diffusions reflected at a boundary and analyze their pathwise “episodes” away from the boundary through Itô’s excursion theory. Under a fixed height cap of a>0, each excursion is equipped with three natural marks: its lifetime ζ,

Venous Thromboembolism in Pediatric Bone Sarcoma Patients: A 10‐Year, Single‐Institution Experience Encompassing the COVID‐19 Pandemic

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

Revisiting the Milky Way stellar long bar and the 3 kpc arm★

Astronomy & Astrophysics
Context. One of the most difficult and unexplored regions of the Milky Way is the highly extincted in-plane central region within the Galactic coordinates 10◦ ≲ |ℓ| ≲ 30◦, |b| ≲ 3◦, where we have the long-bar and 3 kpc arm with intermediate-age stellar ...

Use of local anesthesia in ear surgery: technique, modifications, advantages, and limitations over 30 years’ experience

The Egyptian Journal of Otolaryngology, 2016
En Abstract Background Local anesthesia (LA) is safe and well established for a variety of ear operations. It has many advantages compared with general anesthesia (GA).

Local Variation of Diffusion in Local Time

The Annals of Probability, 1973
Let $X(t), X(0) = 0$, be a nonsingular diffusion in the natural scale in a neighborhood of 0, and let $\mathbf{f}(t, x)$ be its local time. The local behavior of $X(\mathbf{f}^{-1}(t, 0))$ is studied, and used to obtain upper and lower functions of a new type for $X(t)$ at $t = 0$.

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
