We present a programming methodology and runtime performance case study comparing the declarative data flow coordination language S-NET with Intel’s Concurrent Collections (CnC). As a coordination language S-NET achieves a near-complete separation of concerns between sequential software components implemented in a separate algorithmic language and their parallel orchestration in an asynchronous...

Poly(L-lactide) (PLLA) is a semicrystalline thermoplastic which belongs to a biocompatible, biodegradable and bioresorbable polymers. PLLA also fulfills many requirements of the traditional nonbiodegradable packaging materials and it is therefore considered of great value from an ecological point of view due to its biobased character. Nonetheless, there are several aspects such as its slow crys...

The testing devices for performance testing on a CNC machine tool were developed. A small-radius contouring device was employed for checking the dynamic performance of a CNC machine tool. This device was composed of a laser diode and a quadrant sensor. For checking geometric error of a CNC machine tool, a long-radius contouring device was employed. The optic encoder contouring systems were also...

CNC machining is known as an advanced machining process increasingly used for modern materials. This paper outlines modeling methodology applied to optimize cutting parameters during CNC milling with ball end mill tool. The parameters taken into account were radial depth of cut and feed per tooth. A predictive model was based on artificial neural network approach. Key-Words: Modeling, artificia...

CnC is a system for describing the structure of parallel computation, or coordinating the dataand control-flow between the individual steps of a computation [2, 3]. A CnC application specifies a set of discrete step functions, and the data collections used as input to and output from those step functions.1 The CnC coordination language describes the relationship between a specific invocation of...

To determine whether homology-dependent gene silencing or cosuppression mechanisms underlie copy number control (CNC) of Ty1 retrotransposition, we introduced an active Ty1 element into a naïve strain. Single Ty1 element retrotransposition was elevated in a Ty1-less background, but decreased dramatically when additional elements were present. Transcription from the suppressing Ty1 elements enha...

Connexin 43 (Cx43) is expressed in the embryonic heart, cardiac neural crest (CNC) and neural tube, and germline knockout (KO) of Cx43 results in aberrant cardiac outflow tract (OFT) formation and abnormal coronary deployment. Prior studies suggest a vital role for CNC expression of Cx43 in heart development. Surprisingly, we found that conditional knockout (CKO) of Cx43 in the dorsal neural tu...

The purpose of this study was to produce a novel pH sensitive hydrogel with superior thermal stability, composed of poly(acrylic acid) (PAA) and cellulose nanocrystal (CNC). CNC was extracted from kenaf fiber through a series of alkali and bleaching treatments followed by acid hydrolysis. PAA was then subjected to chemical cross-linking using the crosslinking agent (N,N-methylenebisacrylamide) ...

The neural crest is an embryonic stem cell population that gives rise to a multitude of derivatives. In particular, the cranial neural crest (CNC) is unique in its ability to contribute to both facial skeleton and peripheral ganglia. To gain further insight into the molecular underpinnings that distinguish the CNC from other embryonic tissues, we have utilized a CNC-specific enhancer as a tool ...
