Summary
Upgrading computers with solid-state drives (SSDs) significantly improved performance in digital pathology tasks, often more than upgrading computer architecture alone. SSDs offer a cost-effective enhancement for system reliability and user experience.
Area of Science:
- Digital Pathology
- Health Informatics
- Computer Science
Background:
- A department upgraded 87 computers over 3 years to enhance user experience and system reliability cost-effectively.
- Upgrade options included new architecture, solid-state drive (SSD) replacement, or both.
Purpose of the Study:
- To evaluate the impact of different computer upgrade strategies on digital pathology workflows.
- To determine the most effective upgrade type for improving task completion times.
Main Methods:
- Assessed performance across standard use, whole-slide navigation, and whole-slide analysis tasks.
- Measured time to completion as the primary performance metric for each task category.
- Compared the effects of architecture upgrades versus SSD upgrades.
Main Results:
- Solid-state drive (SSD) upgrades demonstrated a greater performance impact than architecture upgrades for most tasks.
- The benefit of SSDs was particularly pronounced in whole-slide viewing, likely due to image tile caching mechanisms.
- Whole-slide image analysis tasks were more sensitive to computer architecture, indicating varied performance bottlenecks.
Conclusions:
- SSD upgrades represent a viable and effective alternative to full computer replacement in certain contexts.
- It is recommended that digital pathology computer replacements include an upgrade to SSDs for optimal performance.

02:24Predicting Reaction Outcomes
10.8K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

01:13Outcomes of Glycolysis
107.1K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

01:11Guidelines for Writing Outcome
3.9K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

01:20Gene-Environment Interactions
1.2K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

02:27Background and Environment Affect Phenotype
7.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:27Exercise and Muscle Performance
2.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
