Desorption/ionization on silicon (DIOS) tandem time-of-flight (TOF/TOF) mass spectrometry (MS) provides high accuracy and significant fragmentation information, particularly in the characterization of biomolecules. DIOS TOF/TOF offers a high-throughput surface-based ionization platform as well as complete fragmentation through high collision energies. The absence of matrix interference in DIOS ...

Phosphopeptides with one and four phosphate groups were characterized by MALDI mass spectrometry. The molecular ion of monophosphopeptide could be detected both as positive and negative ions by MALDI TOF with delayed extraction (DE) and in the reflector mode. The tetraphospho peptide could be detected in linear mode. When MS/MS spectra of the monophospho peptides were obtained in a MALDI TOF TO...

Time-of-flight (ToF) cameras are becoming more and more popular in computer vision. In many applications 3D information delivered by a ToF camera is used, and it is very important to know the camera’s extrinsic and intrinsic parameters, as well as precise depth information. A straightforward algorithm to calibrate a ToF camera is to use a standard color camera calibration procedure [12], on the...

1. Intoroduction Recently, various time-of-flight (TOF) range imagers [1-4] have been developed, and are becoming popular in 3D acquisition cameras. This is because TOF range imagers have a high-speed capturing capability, and their millimetric range resolutions are sufficient for their applications such as gesture recognition. However, to apply the TOF range imagers to contactless 3D scanners,...

We tested the suitability of two spectroscopic methods, x-ray photoelectron spectroscopy (XPS) and time of flight secondary ion mass spectrometry (ToF-SIMS), in the recognition of bacterial and eukaryotic cell footprints on implant surfaces. Human mesenchymal stem cells (MSCs) and Staphylococcus aureus were cultured on sample surfaces and detached using trypsin. Scanning electron microscopy con...

Tetralogy of Fallot (TOF) is a structural congenital heart defect with functional significance, occurring 1 in 3,300 live births. Several studies have reported mutations in essential transcription factors responsible for the development of TOF. NKX2.5 is a homeobox containing transcription factor, expresses at various stages of heart development. The rationale of this study was to estimate the ...

OBJECTIVE To investigate facial nerve monitoring in patients receiving the partial nondepolarizing neuromuscular blocking agents (NMBAs), remifentanil and propofol. METHODS Patients with normal facial function and advanced middle-ear disease were enrolled. For total intravenous anaesthesia (TIVA), propofol and remifentanil were infused as induction/maintenance anaesthesia. Stimulation thresho...

BACKGROUND Abnormal expression of connexin 43 (Cx43) has been reported to play an important role in the development of conotrunccal anomalies. However, less is known about the underlying reason for its abnormal expression. MicroRNAs (miRNAs), as an important part of gene expression regulation, have been implicated in some cardiac diseases. This study aimed to investigate the expression of Cx43 ...

Three-dimensional imaging using Time-of-flight (ToF) sensors is rapidly gaining widespread adoption in many applications due to their cost effectiveness, simplicity, and compact size. However, the current generation of ToF cameras suffers from low spatial resolution due to physical fabrication limitations. In this paper, we propose CS-ToF, an imaging architecture to achieve high spatial resolut...
