Two types of cooperation between the photons in multiple scattering lasing and their possible application

Physics Open
The two types of cooperative effects between the converted photons in the multiple steps of Raman lasing are proposed. The first type involves the cooperative process between the photons of one of the steps of Raman conversion.

THE KINETICS OF SENESCENCE [PDF]

Journal of General Physiology, 1924
The course of decline of vitality with age due to the process of senescence, when not complicated by the process of growth, follows a simple exponential law; that is the degree of vitality or of senescence (defining vitality as the reciprocal of senescence) at any moment is, regardless of age, a constant percentage of the degree of vitality or ...

Hip Manipulation Increases Electromyography Amplitude and Hip Joint Performance: A Double-Blind Randomized Controlled Study

Life
(1) Background: Activation of the gluteus medius (GM) muscle while minimizing the involvement of the tensor fascia latae (TFL) is crucial in treating many lower limb and lumbar spine injuries. Previous studies have demonstrated the effectiveness of joint

The Impact of a Single Hip Manipulation on Quadriceps Activity and Performance: A Randomized Study

Biomedicines
Background/Objectives: Optimal activation of the quadriceps femoris, particularly the vastus medialis, while minimizing excessive activation of the vastus lateralis, is crucial for treating knee injuries like ACL ruptures and patellofemoral pain syndrome.

Habitual Cross-legged Sitting Increases Lumbopelvic Rotation Asymmetry

Physical Therapy Korea
Background: Cross-legged sitting posture (CLSP) is common in daily life but may cause asymmetrical loading of the pelvis and spine, potentially leading to postural imbalance and musculoskeletal problems.

Thermal and photo-stability of the antioxidant potential of Spirulina platensis powder

Brazilian Journal of Biology
This work aimed to evaluate the thermal and photo stability of the antioxidant potential (AP) of the Spirulina platensis biomass. Thermal stability was established at 25ºC, 40ºC and 50ºC for 60 days, in the dark, protected from light. Photo stability was

Comparison of the Pelvic Rotation Angle During Hip Lateral Rotation in the Standing and Prone Positions in Participants With and Without Tensor Fasciae Latae/Iliotibial Tract Tightness

Physical Therapy Korea
Background: Tensor fasciae latae (TFL) and iliotibial tract (ITB) tightness can pull the pelvis during hip lateral rotation (HLR), increasing pelvic rotation due to muscle tension.
