Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Protein Networks02:26

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.4K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Veins of Upper Limbs01:17

Veins of Upper Limbs

4.3K
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

7.2K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Area of Science:

  • Oculoplastic surgery
  • Medical image analysis
  • Artificial intelligence in medicine

Background:

  • Upper blepharoplasty is a common cosmetic procedure in East Asia, with specific aesthetic goals for natural Asian double eyelids.
  • Advancements in AI, including UNet and PointRend, improve medical image segmentation for post-operative evaluation.
  • This study leverages deep neural networks for objective analysis of facial images in blepharoplasty.

Purpose of the Study:

  • To apply deep learning for objective morphological parameter assessment in blepharoplasty.
  • To evaluate the precision and reproducibility of AI-based measurements against manual methods.
  • To correlate objective eyelid parameters with patient-reported aesthetic outcomes.

Main Methods:

  • Analysis of 102 eyes from revisional blepharoplasty patients and 100 eyes from volunteers with natural double eyelids.
  • Automated evaluation of four key eyelid parameters: pre-tarsal show, corneal visibility ratio, dynamic value, and crease depth.
  • Comparison of automated measurements with manual measurements and assessment of patient satisfaction using FACE-Q surveys.

Main Results:

  • High intraclass correlation coefficients (0.965-0.975) between automated and manual measurements.
  • Significant long-term changes in eyelid morphology post-surgery (decreased pre-tarsal show/crease depth, increased corneal visibility/dynamic value).
  • High patient satisfaction (87.6) negatively correlated with pre-tarsal show (r = -0.814, p = 0.000).

Conclusions:

  • Deep neural network technique provides precise and reproducible automated measurements of eyelid morphology.
  • Objective evaluation of surgical outcomes for blepharoplasty is enabled by AI.
  • AI-driven analysis aids surgeons in assessing outcomes and planning revisions for improved patient satisfaction.
