We announce a tool for mapping E derivations to Mizar proofs. Our mapping complements earlier work that generates problems for automated theorem provers from Mizar inference checking problems. We describe the tool, explain the mapping, and show how we solved some of the difficulties that arise in mapping proofs between different logical formalisms, even when they are based on the same notion of...

Green fluorescent protein (GFP) is a useful biomolecule in biotechnology; however, its price makes widespread application prohibitive. To overcome this issue, recently, the use of aqueous two-phase systems (ATPS) for GFP purification was proposed as an alternative platform to reduce processing costs. Aligned with goal, study performed bioprocess modelling coupled economic analysis using softwar...

BACKGROUND Accurate placement of pedicle screw during Anterior Transpedicular Screw fixation (ATPS) in cervical spine depends on accurate anatomical knowledge of the vertebrae. However, little is known of the morphometric characteristics of cervical vertebrae in Chinese population. METHODS Three-dimensional reconstructions of CT images were performed for 80 cases. The anatomic data and screw ...

We investigated variations in cell growth and ATP Sulfurylase (ATPS) activity when two cyanobacterial strains—Synechocystis sp. PCC6803 Synechococcus WH7803—were grown conventional media, media with low ammonium, sulfate a high CO2/low O2 atmosphere. In both organisms, transition adaptation to the reconstructed environmental resulted decrease ATPS activity. This variation appears be decoupled f...

Liquid-liquid segmented flows in microchannels have been extensively investigated the context of nanoparticle synthesis. The enhanced mixing slugs results monodispersed particles. Earlier studies focused on Organic-Aqueous Systems (OAS). nanoparticles synthesized presence organic solutions limited applications. An alternative green route for synthesis can be developed using an Aqueous Two-Phase...

BACKGROUND Evaluation of latest generation automated attenuation-based tube potential selection (ATPS) impact on image quality and radiation dose in contrast-enhanced chest-abdomen-pelvis computed tomography examinations for gynaecologic cancer staging. METHODS This IRB approved single-centre, observer-blinded retrospective study with a waiver for informed consent included a total of 100 pati...

STUDY DESIGN Randomized laboratory cadaver study. OBJECTIVE The objective of this study was to determine the accuracy of anterior transpedicular screw placement in the cervical spine using conventional fluoroscopy versus computer-assisted navigation. SUMMARY OF BACKGROUND DATA Traditionally, global cervical instability has required anterior and posterior fixation due to the superior biomech...
