In this paper, we present a carry skip adder (CSKA) structure that has a higher speed yet lower energy consumption compared with the conventional one. The speed enhancement is achieved by applying concatenation and incrementation schemes to improve the efficiency of the conventional CSKA (Conv-CSKA) structure. In addition, instead of utilizing multiplexer logic, the proposed structure makes use...

OBJECTIVE The study was designed to compare helical CT with varying pitch and reconstruction intervals and conventional CT for revealing pulmonary nodules in a model that simulates respiratory motion in children. MATERIALS AND METHODS CT scans were obtained in an experimental model with one nodule (3 or 10 mm) in each scan. One-second scans were obtained at rates of 10, 20, and 30 respiration...

Context. In recent times, large organic molecules of exceptional complexity have been found in diverse regions the interstellar medium. Aims. this context, we aim to provide accurate frequencies ground vibrational state two key aliphatic aldehydes, n -butanal and its branched-chain isomer, i-butanal, enable their eventual detection We also want test level that chemistry can reach star formation...

SEMANTIC SYNTAX (SeSyn) is a direct continuation of work done in the '60s and '70s under the name of GENERATIVE SEMANTICS. The main component of SeSyn is a rule system (the syntax) which transforms the Semantic Analysis (SA) of any given sentence into a Surface Structure (SS) of that sentence. The SAs represent meanings in a higher order Predicate Calculus, according to a small set of context-f...

We argue, reason, cajole, and persuade — we deploy rhetoric — because we are social animals endowed with a symbolic mode of thought and communication who seek to shape our social environment, to compete, and to cooperate. As rhetoricians, philosophers, and semiologists have regularly noticed, some patterns of argumentation and cajolery are more successful than others. These patterns of usage — ...

Local hemodynamic changes that accompany changes in brain activity cause local magnetic resonance imaging (MRI) signal changes. Functional MRI (fMRI) is the name used for the group of MRI techniques used to detect these changes to map human brain activation. In this dissertation, eight studies were carried out which included the dissection of activation–induced MRI signal change components and ...

Self-replicating loops presented to date are usually worlds unto themselves, inaccessible to observer once the replication process is launched. In this paper we present a self-replicating loop which allows for user interaction. Specifically, the user can control the loop’s replication as well as the size of the replica. After presenting the design of this novel loop, we delineate its physical i...

Strains are applied to the integration procedure in nonlinear increments todecrease the errors arising from the linearization of plastic equations. Two deformationvectors are used to achieve this. The first vector is based on the deformations obtained bythe first iteration of the equilibrium step, and the second is acquired from the sum of thesucceeding iterations. By applying these vectors and...

We introduce and study a simple generic model of neutral evolution of genotypes, designed to provide a feasible and general method for quantifying excess evolutionary activity|the extent to which evolutionary activity is the product of adaptive evolution. We compare the behavior of the generic neutral model against two other models: Packard's agent-based model of the evolution of sensory-motor ...

The edifice of peer-reviewed literature, particularly in neuroradiology, has new technology as one of its major building blocks. Indeed, one of the easiest paths to publication is the application of a new technological “toy” to a neurodiagnostic problem, or a refinement of that toy to allow a new application (take if from one with shameless experience). For example, with each new iteration of t...
