Sensory Modalities01:15

Sensory Modalities

3.7K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Nuclear Stability03:18

Nuclear Stability

22.9K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

RNA Stability

35.6K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Stability

392
The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

Stability of structures

491
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Pole and System Stability01:24

Pole and System Stability

928
The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Traumatology

Background:

  • Chronic acromio-clavicular dislocation presents significant treatment challenges.
  • Various anatomical and non-anatomical surgical techniques exist for management.
  • Assessing outcomes of novel hybrid surgical approaches is crucial.

Purpose of the Study:

  • To evaluate the clinical and radiological outcomes of chronic acromio-clavicular dislocation.
  • To assess the efficacy of a hybrid technique combining semitendinosus autograft and synthetic sutures.

Main Methods:

  • A cohort of 21 patients with chronic acromio-clavicular dislocation (Grades III-V) were treated between July 2021 and January 2025.
  • The hybrid technique involved biological semitendinosus autograft and synthetic non-absorbable sutures.
  • Post-operative assessments included Constant shoulder and Acromio-clavicular joint instability scores, alongside radiological evaluation for arthritis, ossification, osteolysis, and joint distances.

Main Results:

  • The mean patient age was 28.5 years, with a mean follow-up of 24.3 months.
  • Excellent post-operative scores were achieved: Acromio-clavicular joint instability (93.14) and Constant shoulder (90.14).
  • No cases of recurrent dislocation, arthritis, or distal clavicle osteolysis were observed.

Conclusions:

  • Bi-modal stabilization with a hybrid autograft and suture technique is effective for chronic acromio-clavicular dislocation.
  • This method offers a reliable surgical option with a low incidence of complications impacting functional outcomes.
