Monitoring Change and Recovery of an Embayed Beach in Response to Typhoon Storms Using UAV LiDAR

Drones
The monitoring of beach topographical changes and recovery processes under typhoon storm influence has primarily relied on traditional techniques that lack high spatial resolution. Therefore, we used an unmanned aerial vehicle light detection and ranging

STUDY OF ERROR ANALYSIS AND THE EFFECTS OF RESAMPLING ON DIFFERENT DEMS

International Journal of Research in Engineering and Technology, 2015
Resampling is the method of creating new pixels of different pixel size with respect to the original, using some interpolation technique from some existing pixels. Sometimes, the process may be as simple as duplication. Various approaches have been made to classify terrain based on the DEMs. To classify DEMs based on the slope into morphometric classes

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.

Geomorphometric comparison of DEMs built by different interpolation methods

Landform Analysis, 2017
One of the most important stages of creating DEMs is the selection of a suitable interpolation algorithm. In this paper I decided to take a look at the most popular methods of data interpolation: Inverse Distance Weighting, Natural Neighbour, Spline, Radial Basis Functions, Local Polynomial and Kriging.

Referral Patterns and Diagnostic Timeliness in Pediatric Cancer: A Hospital‐Based Study in Indonesia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely diagnosis and treatment are critical for improving survival among children with cancer. In low‐ and middle‐income countries (LMICs), delays are common and may be influenced by fragmented referral pathways and diagnostic limitations.

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Language, Culture, and Cancer: Qualitative Insights Into Communication Disparities Among Spanish‐Speaking Caregivers of Children With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Latino children are projected to make up nearly one‐third of United States (US) children by 2060, and many of their caregivers speak Spanish. Prior survey research has documented communication difficulties for Spanish‐speaking caregivers of children with cancer, but contemporary qualitative data are limited.

Comparison of DEMs generated using different data sources at a mountain site

Facta universitatis - series: Architecture and Civil Engineering
The paper analyzes digital elevation models (DEM) of the same area based on different sources and methods of geospatial data collection. An open-source DEM was created in the mountainous area of Colus County, which is the northern part of the US state of California.

Comparison and Validation of Different DEM Data Derived from InSAR

Procedia Environmental Sciences, 2012
AbstractHigh accuracy DEM (Digital Elevation Model) can be derived from SAR (Synthetic Aperture Radar) acquisitions by InSAR (Interferometric synthetic aperture radar) technique. The principle of InSAR is briefly introduced in this paper. And DEM measurements are compared with the 1:50,000 China DEM to validate the method.
