Cyber-physical systems and hard real-time systems have strict timing constraints that specify deadlines until which tasks must finish their execution. Missing a deadline can cause unexpected outcome or endanger human lives in safety-critical applications, such as automotive or aeronautical systems. It is, therefore, of utmost importance to obtain and optimize a safe upper bound of each task’s e...

Software Programmable Memories, or SPMs, are raw on-chip memories that are not implicitly managed by the processor hardware, but explicitly by software. For example, while caches fetch data from memories automatically and maintain coherence with other caches, SPMs explicitly manage data movement between memories and other SPMs through software instructions. SPMs make the design of on-chip memor...

A hydro-optical algorithm based on reflectance at 555nm has been used in the past for suspended particulate matter concentrations (SPM) retrieval from SeaWiFS over the Belgian coastal (case II) waters in Southern North Sea. The extra spectral resolution of MERIS offers the possibility of improvements, though necessitates algorithm recalibration. This study presents the calibration of the hydro-...

This paper develops and tests a privacy-preserving business process that supports the selection of a contract manufacturer by an original equipment manufacturer (OEM), and the determination of whether the OEM or the chosen contract manufacturer will procure each of the components to be used in the manufacture of the OEM’s branded product. Our ‘‘secure price-masking (SPM)’’ technology contribute...

22 23 Polyamines are absolute requirements for cell growth. When in excess, P. aeruginosa possesses 24 six γ-glutamylpolyamine synthetases (GPSs) encoded by the pauA1-pauA7 genes to initiate 25 polyamine catabolism. Recently, the pauA2 mutant was reported to lose the capability to grow on 26 spermine (Spm) and spermidine (Spd) as sole carbon and nitrogen sources. Although this mutant 27 grew no...

Ocean color satellite sensors are powerful tools to study and monitor the dynamics of suspended particulate matter (SPM) discharged by rivers in coastal waters. In this study, we test the capabilities of Landsat-8/Operational Land Imager (OLI), AQUA&TERRA/Moderate Resolution Imaging Spectroradiometer (MODIS) and MSG-3/Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensors in terms of sp...

Water, suspended particulate matter (SPM), and sediment samples were collected from ten rivers in Tianjin and analyzed for 16 polycyclic aromatic hydrocarbons (PAHs), dissolved organic carbon (DOC), particulate organic carbon (POC) in SPM and total organic carbon (TOC) in sediment. The behavior and fate of PAHs influenced by these parameters were examined. Generally, organic carbon was the prim...

Metallo-β-lactamases (MBLs) catalyse the hydrolysis of almost all β-lactam antibiotics. We report biophysical and kinetic studies on the São Paulo MBL (SPM-1), which reveal its Zn(ii) ion usage and mechanism as characteristic of the clinically important di-Zn(ii) dependent B1 MBL subfamily. Biophysical analyses employing crystallography, dynamic 19F NMR and ion mobility mass spectrometry, howev...

Thirty-four spermidine (SPD) and spermine (SPM) derivatives with aromatic substituents were synthesized and tested as inhibitors of specific binding of the NMDA channel blocker [3H]MK-801 to membranes prepared from rat hippocampus and cerebral cortex. SPD and SPM derivatives with aromatic substituents at the primary amino groups were the most potent inhibitors (IC50 3.9-4.7 microM). These compo...

Spontaneous pneumomediastinum (SPM); also known as mediastinal emphysema, is a rare and usually benign self-resolving appearance of extraluminal air in the mediastinum without any underlying trigger. This is an uncommon disorder mostly seen in the young males and classic clinical presentation is with chest pain, dyspnea, cough and appearance of subcutaneous emphysema. Although several connectiv...
