Most mechanical CAD systems use line and circle(ruler and compass) as basic drawing tools. In this paper we introduce a class of new drawing tools: the conic. We proved that the class of diagrams within the drawing scope of this new tool is larger than that can be drawn with line and circle. Actually, we proved that a diagram can be drawn with conic if and only if this diagram can be described ...

Abstract Background The craniovertebral angle (CV angle) measurement is a convenient and easy clinical method for the cervical posture assessment. “Markus Bader (MB) ruler software” assists to measure angles distances on computer screen. MB-ruler protractor almost transparent; hence, it can be easily used Many studies in physiotherapy have this software postural assessment with photographic met...

Many compilers, synthesizers, and theorem provers rely on rewrite rules to simplify expressions or prove equivalences. Developing can be difficult: may subtly incorrect, profitable are easy miss, rulesets must rechecked extended whenever semantics tweaked. Large also challenging apply: redundant slow down rule-based search frustrate debugging. This paper explores how equality saturation, a prom...

In hippocampal CA1 cells, distance-dependent synaptic scaling (Nat. Neurosci. 3 (2000) 895, J. Neurosci. 21 (2001) 9151) helps maintain a “dendritic democracy” (Curr. Biol. 11 (2001) R10) where distal and proximal synapses on average contribute equally to the cell’s 7ring. A “dendritic ruler”, for example a concentration gradient, might be necessary for synaptic scaling. Alternatively, synapses...

Shall We Kill or Enslave Caesar? Analyzing the Caesar Model When a society overthrows a ruler – call the ruler Caesar – what determines whether Caesar is killed or enslaved? This paper presents a model of killing versus enslaving Caesar, based on a new theory which unifies justice, status, and power. The model pertains to societies which value ordinal goods like bravery, yielding predictions fo...

Does the nebulin ruler hypothesis stand up to experimental tests? Nebulin’s possible role as a ruler has been tested in several ways, and thus far the results appear to argue against its controlling thin filament length. Two such pieces of evidence are: first, the nebulin molecule appears to be somewhat shorter than the thin filament in most fibre types; and second, in nebulin gene knockout mod...

How educators and students process and respond to emotions can either enhance or impede the development of the whole child. Social and emotional learning (SEL) refers to the processes of developing social and emotional competencies, which depend on individuals’ capacity to recognize, understand, and manage emotions (i.e., emotional intelligence or EI). Consensus across disciplines about the imp...

Readiness to change is a crucial issue in the treatment of substance use disorders. Experiences with methadone maintenance treatment (MMT) has shown that continuous drug and alcohol use with all its consequences characterize most MMT programs. In a prospective study of drug abusers seeking opiate agonist maintenance treatment in the City of Copenhagen, subjects were administered the Addiction S...
