Upon nutrient limitation, budding yeasts like Saccharomyces cerevisiae can be induced to adopt alternate filament-like growth patterns called diploid pseudohyphal or invasive haploid growth. Here, we report a novel constitutive pseudohyphal growth state, sharing some characteristics with classic forms of filamentous growth, but differing in crucial aspects of morphology, growth conditions and g...

This section1 discusses Scenario-Aware Dataflow (SADF), which is a generalization of dataflow models with strict periodic behavior. Like many dataflow models, SADF is primarily a coordination language that highlights how actors (which are potentially executed in parallel) interact. To express dynamism, SADF distinguishes data and control explicitly, where the control-related coherency between t...

Scenario-aware dataflow (SADF) is a prominent tool for modeling and analysis of dynamic embedded dataflow applications. In SADF the application is represented as a finite collection of synchronous dataflow (SDF) graphs, each of which represents one possible application behaviour or scenario. A finite state machine (FSM) specifies the possible orders of scenario occurrences. The SADF model rende...

Dataflow formalisms are useful for specifying signal processing and streaming applications. To adequately capture the dynamic aspects of modern applications, the formalism of Scenario-Aware Dataflow (SADF) was recently introduced, which allows analysis of worst/best-case and average-case performance across different modes of operation (scenarios). The semantic model of SADF integrates non-deter...

The effect of the South African Defence Force's (SADF) military training on the endurance fitness of recruits was investigated. Pre-military training maximal O2 consumption (53,14 ml/kg/min) did not change significantly during the study. In contrast, lactate turnpoint (ml O2/kg/min) and treadmill performance time were moderately enhanced (7,5% and 8% respectively; P less than 0,05) by the initi...

In this study, a sulfur-based autotrophic denitrifying filter (SADF) was developed for the purpose of removing nitrate from simulated recirculating mariculture wastewater. Results showed that over 90% could be effectively eliminated by utilizing thiosulfate as electron donor, with molar ratio thiosulfate-S to 2:1 or greater. Additional batch tests confirmed suitable sulfur source removal even w...
