Background and Objective: Umbilical Cord blood (UCB) hematopoietic stem cell (HSC) transplantation is a therapeutic approach for the treatment of malignant and non-malignant hematologic disorders due to ease of collection, lack of risk for donors and lower levels of infection. Moreover, it is considered a good alternative for bone marrow HSC transplantation. The main limitation of their use is ...

Conventional two-dimensional (2D) plasmonic arrays provide electric field intensity enhancement in the plane, typically with a surface coverage around 50% in the plan-view. Here, we show nanoplasmonic three-dimensional (3D) surfaces with 100% surface coverage enabling strong surface-normal field enhancement. Experimental measurements are found to agree well with the full electromagnetic solutio...

Many researchers assume that the distribution of the nodes is done in a two-dimensional environment in the reason that the height of this network is negligible compared to its width and length. However, in the reality, three-dimensional (3D) deployment of the wireless sensor networks is used. Therefore, many applications require 3D architecture such as underwater, space communications, atmosphe...

We introduce a novel method for three-dimensional metamorphosis between two polyhedral objects with different topologies. The 3D objects are represented as multiple 2D images and well-understood 2D morphing techniques are used to morph between their 2D representations. The resulting 2D morphs are used to reconstruct the intermediate 3D objects. The user controls the metamorphosis by matching fe...

The twoand three-dimensional ~2D and 3D! versions of ALEGRA-HEDP @A. C. Robinson and C. J. Garasi, ‘‘Three-dimensional Z-pinch wire array modeling,’’ Computer Physics Communications, submitted# have been utilized to simulate discrete wire effects including precursor formation in 2D (r-u plane! and nonuniform axial ablation ~3D!. Comparisons made between 2D and 3D simulations indicate that 2D si...

Purpose. To compare the measurements of fetal nuchal fold (NF) thickness by two-dimensional (2D) and three-dimensional (3D) ultrasonography using the three-dimensional extended imaging (3DXI). Methods. A cross-sectional study was performed with 60 healthy pregnant women with a gestational age between 16 and 20 weeks and 6 days. The 2D-NF measurements were made as the distance from the outer sku...

Two-dimensional (2D) transducer arrays represent a promising solution for implementing real time three-dimensional (3D) ultrasound elastography. 2D arrays enable electronic steering and focusing of ultrasound beams throughout a 3D volume along with improved slice thickness performance when compared to one-dimensional (1D) transducer arrays. Therefore, signal decorrelation caused by tissue motio...

INTRODUCTION Laparoscopic adrenalectomy is today considered the gold standard of treatment for adrenal tumors. The development of high definition cameras does not eliminate the major limitation of two-dimensional (2D) laparoscopy: lack of depth perception and loss of spatial orientation. Tree-dimensional (3D) HD laparoscopy was developed as an alternative to conventional 2D laparoscopy. METHO...

Long-range order and phase transitions in two-dimensional (2D) systems-such as magnetism, superconductivity, and crystallinity-have been important research topics for decades. The issue of 2D crystalline order has reemerged recently, with the development of exfoliated atomic crystals. Understanding the dimensional limit of crystalline phases, with different types of bonding and synthetic techni...

In this review, we discuss the microenvironmental cues that modulate the status of cells to yield physiologically more relevant three-dimensional (3D) cell-based high throughput drug screening (HTS) platforms for drug discovery. Evidence is provided to support the view that simplifying 3D cell culture platforms for HTS applications calls for identifying and validating ubiquitous three-dimension...
