Elementary Functions and Approximate Computing [PDF]

, 2020
International audienceWe review some of the classical methods used for quickly obtaining low-precision approximations to the elementary functions. Then, for each of the three main classes of elementary function algorithms (shift-and-add algorithms ...

Cache Coherence for Approximate Computing [PDF]

, 2020
Coherence induced cache misses are an important aspect limiting the scalability of shared memory parallel programs. Many coherence misses are avoidable, namely misses due to false sharing – when different threads write to different memory addresses that ...

Design of energy-efficient approximate squaring circuits for error-resilient signal and image processing applications

Ain Shams Engineering Journal
Standard arithmetic circuits are basic building blocks of digital systems. Implementing standard arithmetic functions using these arithmetic circuits like squaring, addition, multiplication, and division often consumes significant resources, contributing

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

A new fuzzy regression model based on interval-valued fuzzy neural network and its applications to management

Beni-Suef University Journal of Basic and Applied Sciences, 2017
In this paper, a novel hybrid method based on interval-valued fuzzy neural network for approximate of interval-valued fuzzy regression models, is presented. The work of this paper is an expansion of the research of real fuzzy regression models.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Αυτοματοποιημένες Μεθοδολογίες και Τεχνικές Σχεδίασης και Σύνθεσης Προσεγγιστικού Υπολογισμού για Ενεργειακά Αποδοτικούς Επεξεργαστές Υλικού [PDF]

, 2018
Since the failure of Dennard scaling, energy efficiency has become a first-class design concern in computer systems. Recently, exploiting the intrinsic error resilience of a large number of application domains, approximate computing has emerged as a ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.
