Coenosia flagelliseta Muller & Midgley 2022

Muller 2019; BMSA (D)02271; BMSA type no. 317. Micro-pinned specimen. Specimen deposited in the National Museum, Bloemfontein, South Africa. Paratype ♀ Same data as for Holotype. Paratype ♀ Coenosia flagelliseta sp. nov.; B.S. Muller 2019; BMSA (D)02273; BMSA type no. 318. Micro-pinned specimen, genitalia dissected, stored together with abdomen in vial under specimen. Specimen deposited in the National Museum, Bloemfontein, South Africa. Diagnosis. Males can easily be distinguished from other known species of Coenosia by the whip-like setae and setulae on the thorax and legs. The females have a supramedian posterior seta on the mid tibia, which is absent in the female of C. curiosa, the only other known globuliseta -group species with the female described. Correction. The original BMSA type numbers 306 and 307 assigned to the holotype (BMSA(D)02271, and female paratype (BMSA(D)02273) respectively in Muller (2019) were incorrectly assigned due to an administrative error and were already preoccupied by other specimens in the National Museum, Bloemfontein collection. The new correct numbers are included in the material examined citation above for future reference.Also, the female paratype is also incorrectly referred to as an Allotype under the measurement section in Muller (2019). Distribution. South Africa (Mpumalanga).Published as part of Muller, Burgert S. & Midgley, John M., 2022, How strange: Coenosia curiosa sp. nov.

Design of a genetic muller C-element
No full textjournal articleSynthetic biology uses engineering principles to design circuits out of genetic materials that are inserted into bacteria to perform various tasks. While synthetic combinational Boolean logic gates have been constructed, there are many open issues in the design of sequential logic gates. One such gate common in most asynchronous circuits is the Muller C-element, which is used to synchronize multiple independent processes. This paper proposes a novel design for a genetic Muller C-element using transcriptional regulatory elements. The design of a genetic Muller C-element enables the construction of virtually any asynchronous circuit from genetic material. There are, however, many issues that complicate designs with genetic materials. These complications result in modifications being required to the normal digital design procedure. This paper presents two designs that are logically equivalent to a Muller C-element. Mathematical analysis and stochastic simulation, however, show that only one functions reliably
Muller C-Element Metastability Containment
No full textMetastability is the source of many unexpected errors in synchronous circuits. Its mitigation is very well researched in this domain. In contrast, for asynchronous circuits it is normally assumed that the handshaking inhibits metastability. This is, however, only true within the timing closure of the circuit and in the absence of external faults. Metastability may well arise in asynchronous circuits when latching external input signals or when fault tolerance considerations require relaxing the timing closure. Therefore, this paper studies the vulnerability of asynchronous circuits to metastability at the example of a Muller-C element. Traditional mitigation techniques are applied to this kind of circuits and their tness for Muller-C elements is analyzed
Compact Spintronic Muller C-Element With Near-Zero Standby Energy
No full textThe complementary roles of asynchronous architecture with nonvolatile spintronic devices are explored herein to realize a novel asynchronous logic element. By redesigning the Muller C-element to take advantage of spintronic device non-volatility and area efficiency, benefits such as reduced asynchronous handshaking area overhead, are achieved in addition to instant on/off capabilities for reduced static-power dissipation through power gating. We propose a novel eight transistor and one spintronic device Muller C-element design which is 20% faster and uses 68% of the power of previous non-volatile Muller C-element designs. This spintronic Muller C-element is demonstrated within a four-phase dual-rail asynchronous pipeline resulting in 48% fewer transistors in comparison with the previous designs. Additionally, bundled-data protocol overhead is shown to be reduced by using the spintronic Muller C-element proposed herein. Detailed analysis of the effects of driving transistor width and the tunneling magnetoresistance ratio on device performance characteristics is included
Efficient design of gallium arsenide Muller-C element
No full textA Muller-C element is a fundamental building block of a handshake path in self-timed digital circuits. It is a basic event driven logic (EDL) gate, implementing the AND function for events. The authors present a new, improved design of the Muller-C element using GaAs MESFET technology. A static Muller-C gate is implemented that incorporates modifications of newly introduced, GaAs pseudodynamic latched logic family (PDLL) primitives. The circuit is characterised by very high speed and low power dissipation.7597571,005Q1SCI
Muller C-Element for NEMS
No full textNano-electromechanical switches (NEMS) are a promising chip technology for harsh environments. However, their use with conventional synchronous designs may face hurdles, as wear-out limits their number of switching cycles. In this paper we propose a novel implementation of a Muller C-Element for NEMS devices and present two case studies showing that Quasi Delay Insensitive (QDI) design can significantly decrease the number of switching cycles and thus extend the lifetime of the circuit, potentially even without an increase of the device count. Our results indicate that the benefits of QDI become more pronounced for circuits that have a high proportion of flip-flops, and in cases where slow input causes idle clock cycles. Overall, our approach of using a customized Muller C-Element in a QDI design style shows clear benefits for the considered NEMS technology.</p
