Semantic Map Properties
1) Semantically similar points are in the same map region
2) Point clusters form topics
• Dense areas on map
• Syntactically homogeneous clusters
3) Similar topics are located close to each other
4) Hierarchical topics
• Can be combined or split
• Form larger syntactically homogeneous areas

Durch Betriebsvereinbarung kann für einzelne Arbeitnehmer,
Arbeitnehmergruppen, Betriebsteile oder für den gesamten
Betrieb eine Wochenarbeitszeit zwischen 33 und 43 Stunden
vereinbart werden. Der Arbeitgeber soll die Lage einer
geänderten Wochenarbeitszeit den Arbeitnehmern jeweils 2
Tage im voraus ansagen.
Der Durchschnitt von 38 Stunden pro Woche muß in zwölf
Monaten erreicht werden. Aus betrieblichen Gründen kann
der Ausgleichszeitraum um 3 Monate - bis Ende März des
Folgejahres - ausgedehnt werden.
Wenn der Betrieb wegen Materialmangel oder
Betriebsstörungen die Arbeit morgens nicht aufnehmen kann
oder die Arbeit im Laufe des Tages ruhen muß, wird der Lohn
bis zu 8 Stunden einschließlich der an diesem Tage
geleisteten Stunden bezahlt. Bestehen Ersatzansprüche
gegenüber Dritten, hat der Arbeitnehmer diese dem
Arbeitgeber abzutreten.

Topic Model
microRNA genes are transcribed by RNA polymerase II in the
cell nucleus as long single-stranded RNAs (ssRNA) referred to
as the “primary microRNA”, or “pri-miRNA”. The ssRNA
transcript forms a hairpin loop structure, which signals for
RNA nuclease cleavage by a nuclear protein complex called
Drosha/Dgcr8. The resulting short hairpin RNA is termed
“precursor-microRNA” or “pre-miRNA”. Pre-miRNAs are
released into the cytoplasm by the nuclear export protein
Exportin 5 and undergo cleavage by the enzyme Dicer into
~22 nucleotide-long mature microRNAs. After strand
separation, the single-stranded mature microRNAs become
incorporated into the microRNA induced silencing complex
(miRISC). Through the RISC, the microRNA binds to the 3´UTR
of mRNA molecules by direct base pairing. Binding of miRISC
to a mRNA results in post-transcriptional gene silencing
either through inhibition of mRNA translation or mRNA
destabilization. The 5´UTR region of microRNAs is also known
as seed region (nucleotides 1 through 8) and has the most
crucial impact on targeting and function. MicroRNAs do not
require perfect complementarity for target recognition and a
single microRNA is capable of regulating up to hundred or
more mRNA species.
