Examples of crossing over in the following topics:
-
- For these reasons, it is fairly uncommon for a Member of Congress to cross over parties, but it is not unheard of.
- A member might switch parties, or "cross the floor," for a number of reasons.
- Crossing over can cause difficulties.
- Others who have crossed over have found success: Senator Joe Lieberman served as a Democrat and even ran as the Democratic Vice Presidential nominee in 2000, but after losing the Democratic primary in his home state of Connecticut, ran and was elected as an Independent.
- Senator Lieberman was a Democrat, then crossed over as an Independent, then endorsed a Republican presidential candidate.

- Crossing-over (homologous recombination) is one such mechanism by which DNA variations can occur, and genes can be rearranged.
- Crossing-over is an event that occurs during meiosis when chromatids are in contact with each other and may exchange segments.
- Crossing over occurs during meiosis I, and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes.
- Crossing over is essential for the normal segregation of chromosomes during meiosis.
- Crossing over also accounts for genetic variation, because, due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.

- When a sarcomere contracts, myosin heads attach to actin to form cross-bridges
followed by the thin filaments sliding over the thick filaments as the heads
pull the actin, and this results in sarcomere shortening, creating the tension
of the muscle contraction.
- Alternatively, if the muscle is over contracted then the potential for
further contraction is reduced which will similarly reduce the amount of force
produced.
- The force generated by a muscle
depends on the number of actin and myosin cross-bridges formed, a larger number
of cross-bridges results in a larger amount of force.
- However, cross-bridge
formation is not immediate and so if myofilaments slide over each other at a
faster rate their ability to form cross bridges is, and so force is reduced.
- At a maximum velocity no cross-bridges can form, so no force
is generated resulting in the production of zero power (right edge of graph).

- Ottonian rule was accompanied by renewed faith in the idea of imperium (Latin, roughly translated as "power to command" and referring to the sovereignty of state over individual) and also coincided with a period of significant church reform.
- Furthermore, many of the finest examples of the crux gemmata (jeweled cross) date from Ottonian rule.
- Arguably the finest of these Ottonian jeweled crosses is the Cross of Lothair, dating from around 1,000 AD and housed in the Aachen Cathedral.
- However, the cross was actually commisioned over a century later for Otto III, the Holy Roman Emperor.
- The jewelled Cross of Lothair, c. 1000, is an example of the prestigious metalwork of the time.

- The main inputs of forecasting include time series, cross-sectional and longitudinal data, or using judgmental methods.
- Analysis of cross-sectional data usually consists of comparing the differences among the subjects.
- Cross-sectional data differs from time series data also known as longitudinal data, which follows one subject's changes over the course of time.
- Another variant, panel data (or time-series cross-sectional (TSCS) data), combines both and looks at multiple subjects and how they change over the course of time.
- Panel analysis uses panel data to examine changes in variables over time and differences in variables between subjects.
-
- Cross reactivity occurs when an antibody binds not to the antigen that elicited its synthesis and secretion, but to a different antigen.
- Because an epitope corresponds to such a small region (the surface area of about four to six amino acids), it is possible for different macromolecules to exhibit the same molecular identities and orientations over short regions.
- For instance, antibody cross reactivity may occur against the similar surface structures of various Gram-negative bacteria.
- These antibodies may have been initially raised against the nucleic acid of microorganisms, but later cross-reacted with self-antigens.
- (b) An antibody may cross-react with different epitopes.
-
- Developmental psychology uses scientific research methods to study the changes that occur in human beings over the course of their lives.
- These include longitudinal, cross-sectional, sequential, and microgenetic designs.
- In a cross-sectional study, a researcher observes differences between individuals of different ages at the same time.
- Cross-sequential designs combine both longitudinal and cross-sectional design methodologies.
- Microgenetic design studies the same cohort over a short period of time.

- Hatching and cross-hatching are artistic techniques used to create tonal, shading, and textural effects by drawing closely spaced parallel lines.
- Hatching and cross-hatching are artistic techniques used to create tonal, shading and textural effects by drawing closely spaced parallel lines.
- In Western art, hatching originated in the Middle Ages and became more developed over time.
- Cross-hatch lines are used to provide additional tone and texture and can be oriented in any direction, often overlapping each other to create heavily shaded areas.
- Albrecht Dürer uses hatching and cross-hatching in both the background and foreground of this image.

- The crossing of the Rhine was achieved at four points: One was an opportunity taken by US forces when the Germans failed to blow up the Ludendorff bridge at Remagen, one crossing was a hasty assault, and two crossings were planned.
- Lieutenant General Omar
Bradley and his subordinates quickly exploited the Remagen crossing made on March 7 and expanded the bridgehead into a full scale crossing.
- Having crossed the Rhine, both Army Groups fanned out into the German hinterland.
- By V-E Day, the US 12th Army Group was a force of four armies (First, Third, Ninth and Fifteenth) that numbered over 1.3 million men.
- As the operational commander of some of these forces was Grand Admiral Karl Dönitz, the new Reichspräsident (head of state) of the Third Reich, this signaled that the European war was over.
