Explanations reconsidered [PDF]

open access: yes, 1987
Edna Ullmann-Margalit .introduced the notion of an invisiblehand explanation (I-H explanation) to the philosophical literature in 1978, and made a distinction between "aggregate" and "functional-evolutionary" (F-E) forms of I -H explanations.

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Risk Aggregation [PDF]

open access: yes, 2010
Quantitative Risk Management (QRM) often starts with a vector of oneperiodprofit-and-loss random variables X=(X1,...,Xd)′ defined on some probability space (Ω,I,P). Risk Aggregation concerns the study of the aggregate financial position ψ(X), for some measurable function ψ:Rd→R.

Aggregate stress contribution in asphalt mixtures with the splitting tests based on the three-dimensional (3D) discrete element method (DEM)

open access: yesMaterials Research Express
In this study, the discrete element method (DEM) simulations were employed to assess the asphalt mixture’s splitting strength to investigate the mechanical aspects of asphalt mixtures under various loading conditions, including the stress transmission ...

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

Influence of aggregate size and fraction on shrinkage induced micro-cracking of mortar and concrete

open access: yes, 2009
In this paper, the influence of aggregate size and volume fraction on shrinkage induced micro-cracking and permeability of concrete and mortar was investigated. Nonlinear finite element analyses of model concrete and mortar specimens were performed.

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with
