“…Wire and gate orphans have been explained using examples in [ 18 ], and an interested reader may refer to the same for details. The issue of wire orphans is overcome by imposing the isochronic assumption on primary input forks while the issue of gate orphans is dealt with by performing indicating logic decomposition in QDI circuits [ 19 , 20 ]. Monotonic circuits, as they are non-QDI (internally), neglect the issue of gate orphans since monotonicity is guaranteed for both rising and falling signal transitions between the primary inputs and primary outputs.…”

Addition is a fundamental computer arithmetic operation that is widely performed in microprocessors, digital signal processors, and application-specific processors. The design of a high-speed and energy-efficient adder is thus useful and important for practical applications. In this context, this paper presents the designs of novel asynchronous carry look-ahead adders (CLAs) viz. a standard CLA (SCLA) and a block CLA (BCLA). The proposed CLAs are monotonic, dual-rail encoded, and are realized according to return-to-zero handshake (RZH) and return-to-one handshake (ROH) protocols using a 28-nm CMOS process technology. The proposed BCLA has a slight edge over the proposed SCLA, and the proposed BCLA reports the following optimizations in design metrics such as cycle time (delay), area, and power compared to a recently presented state-of-the-art asynchronous CLA for a 32-bit addition: (i) 32.6% reduction in cycle time, 29% reduction in area, 4.3% reduction in power, and 35.5% reduction in energy for RZH, and (ii) 31.4% reduction in cycle time, 28.9% reduction in area, 4.4% reduction in power, and 34.4% reduction in energy for ROH. Also, the proposed BCLA reports reductions in cycle time and power/energy compared to many other asynchronous adders.

“…[13,17] In the class of the phenothiazine-derived drugs, pipothiazine palmitate 2 was discontinued in 2015 by Sanofi due to global shortage of its active pharmaceutical ingredient ( Figure 1). [18,19] Just recently, Sanofi also reported the permanent discontinuation of the supply of its injectable fluphenazine decanoate 3 by the end of 2018, due to manufacturing issues of the active pharmaceutical ingredient. [20,21] Both of these phenothiazines are structurally related to pipothiazine 1 (Figure 1).…”

The continuous flow synthesis of a model phenothiazine antipsychotic is presented herein, using 3‐chloropropionyl chloride as a central building block. The basic phenothiazine‐derived scaffold is (atom)‐efficiently and mildly synthesized with the aim to present continuous flow technology as a contributor to fast and efficient syntheses of challenging APIs, that are nowadays experiencing supply disruptions and global shortages.
