This paper analyzes the power consumption of an array pipelined multiplier. To precisely realize a low power pipelined multiplier, the analytical model for a clocking system is presented. Simulation results show that the storage element is the key-component in a high performance pipelined multiplier macro. Compared with the conventional DFF and latch, the new low power DFF as PTTFF [6] achieves...

Recently we have proposed Boolean single-fluxquantum (BSFQ) circuits, which like CMOS circuits directly support Boolean primitives, and do not require local synchronization for their elementary cells as well as for their combinational cells. However, only the cell-level timing description of the BSFQ circuits was considered, which did not specify their global timing strategy in a system-level d...

The reaction of 5-hydroxymethylfurfural (5-HMF) with arenes in superacidic trifluoromethanesulfonic acid (triflic acid, TfOH) as the solvent at room temperature for 1-24 h gives rise to 5-arylmethylfurfurals (yields of 17-91%) and 2-arylmethyl-5-(diarylmethyl)furans (yields of 10-37%). The formation of these two types of reaction products depends on the nucleophilicity of the arene. The same re...

Coal will continue to be the most demanded energy source worldwide, which highlights the importance of better understanding current practices and environmental impacts of this industry. Indonesia is the largest coal exporter in the world, but studies evaluating the environmental impacts of the coal industry in this country are missing in the literature. A case study of the Indonesian coal suppl...

2,5-diformylfuran (DFF) is a promising green platform chemical obtainable by selective oxidation of 5-(hydroxymethyl)furfural (HMF). In this work, high-purity DFF was synthesized from HMF and compared to formaldehyde (F) in terms suitability for polymerization aqueous solution with various phenolic model substances that may be depolymerization lignin. Resorcinol, catechol, phloroglucinol formed...

DNA fragmentation is a hallmark of apoptosis (programmed cell death). However, the biological function of apoptotic DNA fragmentation remains unclear. Here, we show that DNA fragmentation factor plays an important role for maintaining genomic stability. Inhibition or loss of the DNA fragmentation factor (DFF)/caspase-activated DNase (CAD), whose nuclease activity is responsible for digesting ge...

Abstract The property of maintaining the lens state liquid crystal (LC) during switching between positive and negative states is made use in fast acquirement multi-focus images without magnification change. A depth from focus (DFF) pipeline that can generate a low-error map an all-in-focus image proposed. scene then obtained via DFF captured images. sensor proposed this paper has advantages sim...

I briefly review some recent results on soft-gluon resummation and present applications to heavy-quark and jet production in hadron collisions. DFF 259-10-96 October 1996 To appear in Proceedings of QCD Euroconference 96, Montpellier, France, July 1996.

Heterogeneous catalytic oxidation of 5-hydroxymethylfurfural (HMF) with molecular oxygen to 2,5-diformylfuran (DFF) was performed on aluminium oxide-supported ruthenium catalysts (Ru/Al2O3). The were analyzed by pH and Brunauer-Emett-Teller (BET) measurement, potential side products measured HPLC-UV. High catalyst activity near-quantitative DFF yield (>99.9 %) achieved in toluene under moderate...

I present some comments on the relationship between the smallx behaviour of the parton (quark and gluon) densities and the scaling violation of the proton structure function F2(x,Q ). DFF 229/6/95 June 1995 ∗Talk given in the session on Proton Structure at the Workshop on Deep Inelastic Scattering and QCD, Paris, April 1995.
