Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber
Advanced Photonics Research, EarlyView.Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

The O-type eclipsing binary SZ Cam revisited
, 2010 We analyse new spectra of the multiple system SZ Cam because previous studies found different values of the primary radial velocity amplitude. The older solutions of light curves also have different ratios of secondary to primary luminosity as inferred ...

TeV GAMMA RAYS: OBSERVATIONS VERSUS EXPECTATIONS & THEORY
Acta Polytechnica, 2013 The scope of this paper is to discuss two important questions relevant for TeV γ-ray astronomy; the pursuit to reveal the origin of cosmic rays in our galaxy, and the opacity of the universe in γ-rays.

High‐Throughput Single‐Nanowire Optoelectronic Characterization Using Microfluidic Technology
Advanced Photonics Research, EarlyView.An ultrathin microfluidic platform enables high‐throughput, in‐line single particle characterization of semiconductor nanowires. Using correlative spectroscopy and imaging, analysis at 240 nanowires per minute, uncovering previously hidden details about intra‐wire disorder and inter‐wire inhomogeneity, is achieved.

Ultra High Energy Cosmic Rays, Z-Shower and Neutrino Astronomy by Horizontal-Upward Tau Air-Showers
, 2003 Ultra High Cosmic Rays (UHECR) Astronomy may be correlated to a primary parental Neutrino Astronomy: indeed any far BL Lac Jet or GRB, sources of UHECR, located at cosmic edges, may send its signal, overcoming the severe GZK cut-off, by help of UHE ZeV ...

Advanced Science, EarlyView.By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.
