Improvements of Synchronous Rectification on LLC-DCX
… rectification (SR) on LLC DC-Transformers (DCXs). Firstly, a current resonance issue caused by the SR controller, and secondly a early turn-off issue from parasitics present in the drain-source sensing path. Two novel methods are proposed to solve the early turn-off issue, and an FPGA based …

Direct Current Transformer (DCX): Converter Integration, Modular Operation, and Efficiency Improvement Through Synchronous Rectification
El Transformador de Corriente Continua (DCX) es un convertidor CC-CC aislado de relación fija, opera sin control en lazo cerrado, generalmente basado en topologías resonantes para maximizar la eficiencia. Está compuesto por un Generador de Tensión Conmutada de Alta Frecuencia, un transformador, un …

Topology and Control Investigation of Soft-Switching DC-DC Converters for DC Transformer (DCX) Applications
… DC-DC converter, namely the DC transformer (DCX), has gained significant popularity. Similar to the passive AC transformer, DCX can bidirectionally convey DC power with very high efficiency. Due to zero-voltage switching (ZVS) and a small root mean square (RMS) current, the open-loop CLLC …

Improvement of Sigma Voltage Regulator - A New Power Architecture
… which is composed by an unregulated converter (DCX) and a regulated buck converter, with a special connection where the inputs are in series while outputs are paralleled. Through this topology, unlike the in-series two-stage where both two stages deliver the full load power, the power will be …

Current Sharing Method for DC-DC Transformers
… It can be replaced by a dc-dc transformer (DCX), which is a semi-regulated or unregulated, single output dc-dc converter. A DCX can be made using a modular design to simplify expansion of the system capacity. To realize this concept, the DCX block must have a current sharing feature. The …

Activation of Early Neural Progenitors Is Required for Traumatic Brain Injury-Induced Hippocampal Neurogenesis
… that this injury depletes doublecoritn (Dcx)-expressing late neural progenitors while activating eGFP-expressing early neural progenitors. To address whether the subsequent recovery of Dcx-expressing late progenitors was derived from activation of early neural progenitors, I generated a …

Modeling Neural Stem Cell Dynamics in Congenital Heart Disease
… contains populations of newly generated (BrdU+/DCX+) neurons in the prefrontal cortex that are produced postnatally. Regional analyses using immunohistochemical staining for doublecortin (DCX), a marker expressed by immature neurons, revealed that DCX+ clusters co-express markers of neuronal …

The effect of voluntary exercise on adult hippocampal neurogenesis in maternally separated rats
… survive to become neurons or astroc ytes (2) EdU/DCX to determine how many EdU labelled cells that have survived for 14 days are immature neurons and (3) Ki-67/DCX to indicate how many mitotically active cells are immature neurons on PND 74. Brain sections were then scanned using a confocal …

Chronic mild social stress increases neurogenesis in adolescent male rats
… or survival (evidenced by BrdU and Doublecortin (Dcx) immunohistochemistry respectively) of cells born at the beginning of the stress procedure. Compared to controls, BrdU-labeling showed chronic stress significantly increased proliferation of cells generated after the stressor had ceased, but …

Application of pharmaceutical technologies to improve the activity of cancer chemotherapeutic agents
… I designed a solid lipid nanoparticle (DCX-SLNs) formulation to improve the delivery of docetaxel into solid tumors and to avoid excipient-related side effects associated with the current Tween 80-based docetaxel formulation. The DCX-SLNs showed improved in vitro cytotoxicity in various …

Effects of Proton Radiation and Pomegranates on Hippocampus and Behavior
… quantified using immunohistochemistry for BrdU+/DCX+ cells. Radiation suppressed cell proliferation (BrdU+) and neurogenesis in the dentate gyrus (BrdU+/DCX+) of the hippocampus. Pomegranate juice increased neurogenesis (DCX+) in the hippocampus of non-irradiated mice. These data highlight the …

High Voltage Synchronous Rectifier Design Considerations
… systems utilize a LLC-based DC transformers (DCX) to provide an efficient means of energy conversion. The LLC-DCX's attractive attributes of soft-switching and high efficiency allure many architects to combine it with an SR system. However, direct implementation of SR on a LLC-DCX will result …

Effects of Testosterone on the Spatial Ecology, Coloration, and Brain Regions in Western Fence Lizards, Sceloporus occidentalis
… neurons, which express the protein doublecortin (DCX), migrate from the ventricles, through the inner plexiform layer and are integrated into the cell layer. Because DCX is only expressed in recently born, migrating neurons, it can be used to measure neurogenesis. In mammals and birds, …
