What is the likely motivation for a person giving up soup after an extended illness? Values Habit Social interactions Positive a
makkiz [27]

Answer:

The correct answer is: Positive Associations.

Explanation:

  • Due to prolonged illness the person has lost all desire to survive.
  • This is the reason why he stopped consuming food.
  • Under such a situation, it is necessary that the person should be exposed to people who can positively counsel the person and make the ill person realise the importance of life.
  • It is necessary to make the person realise what he would gain if he chooses to survive and what he would lose if he chooses to die.
  • It is necessary to remind the person of all the possible goals he could achieve in his life if he chooses to survive.

Mt-UcGAN: Multi-task uncertainty-constrained GAN for joint segmentation, quantification and uncertainty estimation of renal tumo
olga nikolaevna [1]

Multi-task uncertainty-constrained GAN(Mt-UcGAN) for joint segmentation, quantification and uncertainty estimation of renal tumors on CT conclude that the integrated segmentation, quantification, and uncertainty estimate of renal tumors were initially proposed using a multi-task uncertainty-constrained generative adversarial network (Mt-UcGAN).

A novel adversarial technique with uncertainty limitations was put forth by us. Results from the experiment show that Mt-UcGAN can help with clinical tumor assessments.

Additionally, it can give medical professionals feedback on the validity of the findings, enabling them to undertake further visual reviews and revisions of the findings to raise the diagnostic accuracy.

The three main procedures for clinical tumor disease diagnosis are segmentation of renal tumor, measurement of tumor indices (i.e., center point coordinates, diameter, circumference, and cross-sectional area), and segmentation uncertainty estimation.

These tasks have, however, only ever been researched separately until now. It is quite difficult to describe two distinct tasks as a single optimization framework since segmentation and quantification tasks have separate optimization types.

In this study, we present a unified framework for the joint segmentation, quantification, and uncertainty estimate of renal malignancies on CT (Mt-UcGAN: Multi-task uncertainty-constrained GAN ).

Scientists claim that global climate change is threatening many species with extinction. Which statement provides the strongest
solniwko [45]

Answer: Option B

Explanation:

The animals that live on the earth in many different regions because they are adapted to live in a particular habitat. The animals of the polar regions cannot adjust living the Sahara desert and the reptiles living in the desert cannot live in polar regions.

But many of the species are dependent on the seasonal change and they only emergence or produce during specific period of time.

But if due to global climatic change there will be no emergence of particular species and their species will be extinct over a period of time. So, the global temperature needs to be constant in order to support life of the species dependent on the seasonal temperature change.
