  PICTORIAL1
Both moderately severe dysplasia at the dermal-epidermal interface, and a dermal remnant of a "nevus" (area outlined by blue arrows) in which the "nevus" cells are atypical (i.e., variability in nuclear size and nuclear hyperchromatism in the dermal component) are represented.
This pattern tempers the significance of any other cellular patterns that, despite cellularity, would fail to satisfy criteria for the recognition of a vertical growth component; the interpretation must be qualified as conservative on the basis of this focus of regression.
This pattern may be an example of dermal dysplasia ab inflammation as seen in some patients with multiple lesions, in whom some of the lesions are classic halo nevi and some are dermal dysplasias that are more or less free of inflammation.

  Marker interface pattern - Wikipedia, the free encyclopedia
The marker interface pattern is a design pattern in computer science.
This pattern allows a class to implement a marker interface, which exposes some underlying semantic property of the class that cannot be determined solely by the class' methods.
Hybrid interfaces, which both act as markers and specify required methods, are possible but may prove confusing if improperly used.

 Design Pattern Synopses
The Filter pattern is a special case of the Decorator pattern, where a data source or data sink object is wrapped to add logic to the handling of a data stream.
The Composite pattern also allows the objects in the tree to be manipulated in a consistent manner, by requiring all of the objects in the tree to have a common superclass or interface.
The Interface pattern can be used with the Façade pattern to allow different sets of façade and implementation classes to be used without client classes having to be aware of the different classes.

 Painting: Filling, Stroking and Marker Symbols
The 'marker' element defines the graphics that is to be used for drawing arrowheads or polymarkers on a given 'path' element or vector graphic shape.
The 'marker' property specifies the marker symbol that shall be used for all points on the sets the value for all vertices on the given 'path' element or vector graphic shape.
Each marker is drawn on the path by first creating a temporary viewport such that the origin of the viewport coordinate system is at the given vertex and the axes are aligned according to the orient attribute on the 'marker' element.

URI reference to the 'marker' element which shall be used as the arrowhead symbol or polymarker at the given vertex or vertices.
The 'marker' property specifies the marker symbol that shall be used for all points on the sets the value for all vertices on the given 'path' element or basic shape.
'marker' element indicates that the marker needs to be clipped to its viewport, then an implicit clipping path is established at the bounds of the viewport.

 S3C7-Lichenoids, misc
The lichenoid reaction at the dermal-epidermal interface is cell-poor.
In reparative phases, the regenerating epithelium along the dermal-epidermal interface is thin; most of the cells of the regenerating epithelium have the characteristics of regenerating basal keratinocytes.
In lichen striatus, lesions are nevoid and linear; a common histologic pattern is that of a primary lichenoid reaction (3).

 Title
Design Markers, even though focused on documentation, share the root purpose of marker interfaces; namely, to declare adherence to a design contract whose implementation cannot be policed by the language compiler and runtime system.
The JavaDoc for each design marker interface can document its definition, how it needs to be implemented, why it is done, etc. And instead of redundantly copying this info into the comments of each return value DTO class (or leaving it undocumented altogether), each need only declare, “implements ReturnValue”.
Marker interfaces are automatically inherited and therefore automatically referenced on all subclasses, so JavaDoc provides hyperlinks to all documented requirements.

 Chapter 2. Programming With Keel
An interface is a contract - the class implementing the interface agrees to implement certain functionality, and to have a certain set of method signatures.
The interface pattern is almost always an example of separation of concerns at work: The definition of the contract of a class is being separated from the implementation.
This pattern brings the equivalent of pointers to functions to Java, allowing a form of "call-backs" to be used to select the appropriate functionality.

 Marker Interface Pattern
L'intento del Marker Interface Pattern è quello di fornire un modo semplice per indicare una particolarità "semantica" di una classe.
Questo può capitare quando si utilizzano dei patterns che, come il Composite ed il Decorator, fanno perdere l'identità ad un oggetto perchè trattano oggetti "diversi" tramite un'interfaccia comune per comodità.
In sostanza può capitare la necessità di distinguere in qualche maniera oggetti dello stesso tipo ma comunque concettualmente diversi, ed il pattern in questione ci aiuta ad implementare una soluzione "pulita" per avere una distinzione "semantica".

An interface is a contract - the class implementing the interface agrees to implement certain functionality, and to have a certain set of method signatures.
The interface pattern is almost always an example of separation of concerns at work: The definition of the contract of a class is being separated from the implementation.
Each interface is dealing with a single concern, even though the class may be involved in a number of different concern areas when taken as a whole.

The purpose of the state pattern is not to mimic the behavior of state-machines, it is to allow an object to appear to alter its behavior-type at run-time.
The intent of this pattern is to decouple (1) active and passive connection establishment and service initialization from (2) the processing the two endpoints of a service perform once they are connected and initialized.

Able to test emerging HSS interfaces such as PCI Express and Serial ATA, it provides jitter decomposition and asynchronous pattern verification on up to 32 differential channels (eight in parallel) in a fraction of the time of alternative test options, according to the company.
Applying the edge time-stamping capabilities of GuideTech's proprietary Continuous Time Interval Analyzer (CTIA) technology, the GT4000 performs asynchronous HSS interface pattern verification using a "virtual" pattern marker instead of a physical synchronization marker.
According to the company, the physical-marker approach may require half a minute to achieve pattern match and may prove to be unreliable in the presence of large jitter.
