"in contrast"通常用来比较两件事情的不同之处。它可以用在句子的开头或中间来引出对比的内容。例如:
- In contrast to her brother, who loves sports, Sarah prefers reading.
- The new marketing strategy is much more effective in contrast to the previous one.
- The first half of the movie was slow and boring. In contrast, the second half was action-packed and thrilling.

Describe and contrast overloading in Java and Haskell.
Overloading in Java and Haskell are similar in concept but differ in implementation.
In Java, method overloading allows multiple methods to have the same name but with different parameters. The compiler determines which method to call based on the number and type of arguments passed. This allows for more flexibility and readability in code.
For example:
```
public int add(int x, int y) {
return x + y;
}
public double add(double x, double y) {
return x + y;
}
```
In Haskell, function overloading is achieved through the use of type classes. Type classes define a set of functions that can operate on a particular type. This allows for polymorphic behavior and avoids the need for explicit type annotations.
For example:
```
class Addable a where
add :: a -> a -> a
instance Addable Int where
add x y = x + y
instance Addable Double where
add x y = x + y
```
In this example, the `Addable` type class defines the `add` function for types that are instances of the type class. The `instance` keyword is used to define specific implementations of the function for different types.
Overall, overloading in Java and Haskell serve similar purposes but differ in syntax and implementation. Java uses method overloading with different parameter types, while Haskell uses type classes to provide polymorphic behavior.
Contrast recovery
Contrast recovery refers to the ability of an imaging system to accurately detect and measure the contrast between different regions of an image. This is typically measured by comparing the contrast of an image before and after a specific process or procedure, such as the application of a filter or the use of a particular imaging technique.
In medical imaging, contrast recovery is particularly important for procedures such as computed tomography (CT) and magnetic resonance imaging (MRI), where accurate detection of contrast differences can help diagnose a wide range of medical conditions.
Contrast recovery can be affected by a number of factors, including the quality of the imaging system itself, the type of contrast agent used, and the specific imaging technique employed. Different imaging systems may have different levels of contrast recovery, and it is important to choose the appropriate system for the specific medical application.
