In this letter a new technique is introduced for implementing the basic logic functions using analog current‐mode techniques. By expanding the logic functions in power series expressions, and using summers and multipliers, realization of the basic logic functions is simplified. Since no transistors are working in saturation, the problem of fan‐out is alleviated. To illustrate the proposed techn...

A 64-year-old woman with a completely transected posterior sectoral duct following extended hepatectomy underwent a combined operative procedure with interventional radiology and surgery to restore biliary-enteric drainage. The anterior and posterior sectoral ducts were identified, and catheters were inserted into both systems. The posterior sectoral catheter was placed intraoperatively through...

Previous research shows that technical progress at the industry level, measured by sectoral TFP growth, is more localized in continental European countries than in Anglo-Saxon countries. We use EU KLEMS data sets to decompose sectoral TFP for nine European countries by means of a Malmquist approach, in order to separate technical change. Applying Harberger diagrams, we describe the sectoral pat...

CONTEXT In rural Bangladesh, family planning services--previously provided through household visits and satellite clinics--were transferred to static community clinics under the government's sectoral program for 1998-2003, but the next sectoral program reversed the change without a formal evaluation. It is important to assess changes in utilization and coverage to inform further development of ...

Carbon dioxide emissions abatement in a group of countries can result in increased emissions in non-abating countries. This effect has been referred to as carbon leakage. The Kyoto Protocol calls for a number of industrialized countries to limit their emissions while other countries have no abatement commitments. This paper assesses the sectoral and regional determinants of the leakage in a sta...

In this paper we introduce continuous $g$-Bessel multipliers in Hilbert spaces and investigate some of their properties. We provide some conditions under which a continuous $g$-Bessel multiplier is a compact operator. Also, we show the continuous dependency of continuous $g$-Bessel multipliers on their parameters.

In this paper, using a relation between Schur multipliers of pairs and triples of groups, the fundamental group and homology groups of a homotopy pushout of Eilenberg-MacLane spaces, we present among other things some behaviors of Schur multipliers of pairs and triples with respect to free, amalgamated free, and direct products and also direct limits of groups with topological approach.

Abstract: In this paper, we develop a supply chain network game theory model consisting of retailers and demand markets with retailers competing noncooperatively in order to maximize their expected profits by determining their optimal product transactions as well as cybersecurity investments subject to nonlinear budget constraints that include the cybersecurity investment cost functions. The co...

Hydraulic fracturing—the injection of pressurized fluid, often water, to increase recovery of oil or gas—has become increasingly popular in combination with horizontal drilling. Hydraulic fracturing improves production from a well, but requires a significant amount of water to do so and could put pressure on existing water resources, especially in water-stressed areas. To supply water needs, so...

We present the basic structure and performance of CML current mode full adders, that are used as Carry Save Adders (CSA) in combinatorial multipliers. A 1.2 μm BiCMOS technology is used for simulations but the schematic assumes a 2.5-V power supply. Compared with binary voltage mode CSAs, the multivalued current mode CSAs have chip area and power dissipation advantage, but speed disadvantage. T...
