Possible Simple Structures of the Universe to Include General Relativity Effects [PDF]
The general relativity describes the universe properties, the gravity playing a fundamental role. One uses a metric tensor in a Riemann space, g , which should be in agreement with a mass (or energy) tensor in order to satisfy the Einstein equation of

In 1904, the Austrian physicist Fritz Hasenöhrl examined by means of mental experiments the black body radiation in a reflecting cavity. By calculating the work required to keep the cavity moving at constant velocity in opposition to the radiation ...

Photon-Photon Luminosities in Relativistic Heavy Ion Collisions at LHC Energies [PDF]
Effective photon-photon luminosities are calculated for various realistic hadron collider scenarios. The main characteristics of photon-photon processes at relativistic heavy-ion colliders are established and compared to the corresponding photon-photon ...

Monitoring Neutron Radiation in Extreme Gamma/X-Ray Radiation Fields
The monitoring of neutron radiation in extreme high ≈1014 (#/cm2-s) neutron/photon fields and at extremely-low (≈10−3 #/cm2-s) levels poses daunting challenges—important in fields spanning nuclear energy, special nuclear material ...

The impact of radiotherapy on the hypothalamo-pituitary axis: old vs new radiotherapy techniques
Multimodality cancer therapy has led to remarkable improvements in survival of childhood and young adult cancer, with survival rates exceeding 85%. Such remission rates come with their own adverse sequelea or ‘late effects’.

PHOTON-PHOTON INTERACTIONS [PDF]
Abstract A brief summary of the present status of photon-photon interactions is presented. Stress is placed on the use of two-photon collisions to test present ideas on the quark constituents of hadrons and on the theory of strong interactions.

PHOTON-PHOTON COLLISIONS [PDF]
Studies of photon-photon collisions are reviewed with particular emphasis on new results reported to this conference. These include results on light meson spectroscopy and deep inelastic eγ scattering. Considerable work has now been accumulated on resonance production by γγ collisions.

Single-photon microwave photonics
With the rapid development of microwave photonics technology, high-speed processing and ultra-weak signal detection capability have become the main bottlenecks in many applications. Thanks to the ultra-weak signal detection capability and the extremely low timing jitter properties of single-photon detectors, the combination of single-photon detection ...
