Fluctuations in Sonar: A Short Survey [PDF]
The Journal of the Acoustical Society of America, 1974 Sonar fluctuations received intensive study during the hectic days of World War II, when the causes of fluctuation were identified and some quantitative data were obtained at the frequencies and ranges of current interest. Since then, in the search for mean values of the sonar parameters, fluctuations have tended to be neglected as a subject of serious

Weak, Quiet Magnetic Fields Seen in the Venus Atmosphere. [PDF]
, 2016 The existence of a strong internal magnetic field allows probing of the interior through both long term changes of and short period fluctuations in that magnetic field. Venus, while Earth's twin in many ways, lacks such a strong intrinsic magnetic field,

Invariant spin coherent states and the theory of quantum antiferromagnet in a paramagnetic phase [PDF]
, 2000 The consistent theory of the Heisenberg quantum antiferromagnet in the disordered phase with short range antiferromagnetic order was developed on the basis of the path integral for the spin coherent states.

Visual detection of short-wave blood pressure fluctuations
Proceedings of the 16th International Conference on PErvasive Technologies Related to Assistive Environments, 2023 Blood pressure provides important information about a person’s state of health. It changes greatly during physical activity, but blood pressure at rest also indicates abnormal or pathological conditions. However, periodic fluctuations in blood pressure are also superimposed on blood pressure, which have so far been difficult to measure and thus remain ...

Director dynamics in liquid-crystal physical gels [PDF]
, 2007 Nematic liquid-crystal (LC) elastomers and gels have a rubbery polymer network coupled to the nematic director. While LC elastomers show a single, non-hydrodynamic relaxation mode, dynamic light-scattering studies of self-assembled liquid-crystal gels ...

Equilibrium Bending Fluctuations of Short DNA [PDF]
Biophysical Journal, 2009 Short-lengthscale double-stranded DNA (dsDNA) bending elasticity plays an important role in many biological contexts. We measured dsDNA bending fluctuations using small-angle X-ray scattering from bulk solutions of two gold nanoparticles covalently linked by a 42-94 basepair dsDNA chain, freely fluctuating and not subject to external forces or surface ...

Dynamic fluctuations in a Short-Range Spin Glass model [PDF]
, 1995 We study the dynamic fluctuations of the soft-spin version of the Edwards-Anderson model in the critical region for $T\rightarrow T_{c}^{+}$. First we solve the infinite-range limit of the model using the random matrix method.

Multiple extra macular branch retinal vein occlusions in hyperhomocysteinemia
Indian Journal of Ophthalmology, 2014 Hyperhomocysteinemia is a well-known modifiable risk factor for thromboembolism. Retinal vascular occlusion in patients having hyperhomocysteinemia is a known entity, particularly in young patients.

"Optical conductance fluctuations: diagrammatic analysis in Landauer approach and non-universal effects" [PDF]
, 1994 The optical conductance of a multiple scattering medium is the total transmitted light of a diffuse incoming beam. This quantity, very analogous to the electronic conductance, exhibits universal conductance fluctuations.

Periorbital nodular fasciitis arising during pregnancy
Indian Journal of Ophthalmology, 2014 Nodular fasciitis (NF) is a benign proliferation of fibroblasts and myofibroblasts that rarely occurs in the periorbital region. We report what we believe to be the first case of periorbital NF associated with pregnancy. A case of intravascular fasciitis,
