Influence of Penetration Rate on Full-Flow Penetrometer Resistance in Underconsolidated Clay

Journal of Marine Science and Engineering
In the past few years, offshore site investigations have extensively utilized full-flow penetrometers like the Ball and T-bar penetrometers to assess penetration resistance and subsequently analyze the strength characteristics of marine clay.

Toy Models for Galaxy Formation versus Simulations [PDF]

, 2013
We describe simple useful toy models for key processes of galaxy formation in its most active phase, at z > 1, and test the approximate expressions against the typical behaviour in a suite of high-resolution hydro-cosmological simulations of massive ...

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

The Role of EDA in Developing Robust Machine Learning Models for Lithology and Penetration Rate Prediction from MWD Data

Mining
Measure-While-Drilling (MWD) data provide real-time insight into subsurface conditions and drilling performance, yet their complexity and operational noise often hinder reliable modeling. This study demonstrates the role of Exploratory Data Analysis (EDA)

Application of response surface method to the prediction of TBM penetration rate [PDF]

مجله مدل سازی در مهندسی, 2018
Performance prediction of the tunnel boring machine (TBM) is one of the crucial issues for estimating excavation costs and construction time of tunnel projects. TBM performance highly depends on an achieved penetration rate.

CPX‐351 in High‐Risk Relapsed Pediatric Acute Leukemia: Real‐World Phase 1 Data Establishing the FDA‐Approved Dose

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Outcomes for pediatric relapsed/refractory (R/R) acute myeloid leukemia (AML) remain dismal. CPX‐351, a liposomal formulation of cytarabine and daunorubicin, may have less off‐target toxicities than traditional chemotherapies and has shown improved outcomes for adults with newly diagnosed therapy‐related AML.
