In this present report, luminescent ordered multilayer thin films (OMFs) based on oppositely-charged inorganic nanosheets and the different oppositely-charged chromophores were fabricated via layer-by-layer assembly method. Exfoliated layered double hydroxides (LDHs) and montmorillonite (MMT) nanosheets with opposite charges can be expected to provide a pseudo electronic microenvironment (PEM) ...

The error rate (ER) is a crucial criterion in evaluating the performance of a digital communication system. Many ER estimation methods have been described in the literature. Among them, the pseudoerror monitoring solution has attracted special attention due to its consistent performance in different environments and distinctive blind estimation capability, that is, estimating the ER without nee...

OBJECTIVE Currently, pediatric emergency medicine (PEM) physicians have limited data on point-of-care echocardiography (POCE). Our goals were to (1) determine the overall accuracy of POCE by PEMs in assessing left ventricular (LV) systolic function visually, presence or absence of pericardial effusion, and cardiac preload by estimating inferior vena cava (IVC) collapsibility, in acutely ill chi...

The earliest doubts of the validity of the Principle of the Excluded Middle (PEM) can be found in Brouwer’s notes for his dissertation. The actual formulation had to wait for the “Unreliability of the logical principles” paper one year later. It is a curious fact that in the dissertation Brouwer shrugged off the PEM as obvious and ‘uninformative’. He denied it mathematical significance, because...

OBJECTIVES Pediatric emergency medicine (PEM) physicians receive little opportunity to practice and perform chest tube insertion. We sought to develop and validate a scoring tool to assess chest tube insertion competency and identify areas where training is required for PEM physicians. METHODS We developed a 40-point, 20-item (scored 0, 1, or 2) assessment tool entitled the Tool for Assessing...

In recent years, the penetration of fuel cells in distribution systems is significantly increased worldwide. The cell considered an electrochemical energy conversion component. It has ability to convert chemical electrical energies as well heat. proton exchange membrane (PEM) uses hydrogen and oxygen fuel. a low-temperature type that noble metal catalyst, such platinum, at reaction sites. optim...

BACKGROUND Thymidylate synthase (TS), one of the key enzymes for thymidine synthesis, is a target of pemetrexed (PEM), a key agent for the systemic therapy of malignant pleural mesothelioma (MPM) and its overexpression has been correlated to PEM-resistance. In MPM, experimental data report activation of the c-SRC tyrosine kinase suggesting it as a potential target to be further investigated. ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to identify the essential physics that govern the dynamics in PEM fuel cells. Reaction engineering principles are employed to develop a one-dimensional differential PEM fuel cell suitable for elucidating the...
