The aurone, aureusidin 6-O-glucuronide, has been isolated from the antheridiophores of two liverworts, Marchantia berteroana, M. polymorpha and from Conocephalum supradecompositum. It occurs only in these organs in Marchantia. The appea...

An n-dimensional (convex) polytope is said to have few vertices if their number does not exceed n + 3. Similarly, a simplicial n-sphere with few vertices would not contain more than n + 4 of them. We want to show that all such spheres a...

Drosophila genetics has provided the Hedgehog signaling pathway with roughly ordered components, but few mechanistic connections. Several studies now show that the kinesin-related protein Costal-2 provides a physical link between the tr...

By coupling to cholesterol, Hedgehog can be anchored to the cells where it is made, yet to act as a morphogen, it must be able to move away from its source. Novel genes have now been identified that control the release and dispersal of ...

The first and the third authors obtained a minor-summation formula of Pfaffian, which expresses a weighted sum of minors of any rectangular Nike Air Max Thea White matrix in terms of a single Pfaffian. In this paper, as an application o...

We consider the problem of characterizing the sets of externally and internally active elements in a matroid. The main result is a canonical decomposition of the set of elements of a matroid on a linearly ordered set into external and i...

A technique of applying lag screws for treating fractures of the anterior mandible is presented. A review of 41 patients who had lag screws placed to treat such fractures showed that it is a successful method of providing rigid internal...

To reduce the cost of catalyst in catalytic gasification and to eliminate the need for catalyst recovery, the Air Max 2014 Flyknit effect of potassium carbonate and magnesium nitrate catalyst in the gasification of Shen Bei brown coal w...

We study the dependence on initial conditions of two recursive filters for cleaning a contaminated time series from additive outliers. We show that the function in the recursive equation is in general not contractive, but nevertheless t...

Ghost pattern image of a current density filament has been investigated in n-GaAs at 4.2 K. Applying a pulse voltage above the breakdown voltage, a current density filament is observed. After the pulse voltage is switched off, the ghost...
