The hypothetical particles dyons, which carry both electric and magnetic charges simultaneously, are widely
discussed in application to electromagnetic theory and magnetohydrodynamics. Particularly, the dualityinvariant field
equations were suggested with suitable definitions of the dyon’s electromagnetic characteristics. In this study, we propose
an alternative formulation of the dualityinvariant field equations for dyons based on octonion algebra. Octonions have
been used to express the equations for potentials, field strengths, and sources in a more compact and consistent manner.
Additionally, the octonionic form of the energy conservation law for dyons has been derived.

In the present study, I investigate the effect of temperature on fusion crosssections of the 8 B proton halo
projectile. For this purpose, I evaluate two different fusion reactions, 8 B + 28 Si and 8 B +58 Ni, in the available
literature. I apply two different nuclear potentials as a function of temperature. I calculate both fusion crosssections
and nuclear potentials for both reactions and I then compare the theoretical results with the experimental data. This
comparison provides an opportunity for a test of different temperaturedependent potentials in explaining the fusion
crosssections with the 8 B halo nucleus.

Cladding light strippers are essential components in highpower fiber lasers used for removal of unwanted
cladding light that can distort the beam quality or even damage the whole fiber laser system. In this study, an Atomic
Layer Deposition system was used for the first time to prepare the cladding light stripper devices using a 40 nm thick
zirconia layer grown on optical fiber. The thickness of the zirconia coating was confirmed using the Scanning Electron
Microscopy (SEM) and the Ellipsometry techniques. The elemental analysis was also performed using the wavelength
dispersive Xray spectroscopy technique. The Raman spectroscopy and XRD data confirm the structure of the atomic
layer depositiongrown zirconia thin films to be predominantly amorphous. The cladding light stripper devices formed
using the zirconia thin films with the lengths of 8.5 and 15.5 cm were able to strip approximately 30% (~1.5 dB) and
40% (~2.3 dB) of the unwanted cladding light.

In order to enhance the capacitance of the Al/pSi metalsemiconductor structure, the Alq3 thin film was
coated between these two layers using the spin coating technique as the interlayer. The electrical conductivity, real
and imaginary parts of electric modulus, dielectric loss and dielectric constant parameters were examined at the room
temperature by the help of admittance measurements in the 100 kHz to 1 MHz frequency range. The effect of frequency
on the dielectric constant and dielectric loss values is negligible at the negative voltage values, up to about 0.8 V, and
these values rapidly ascended after 0.8 V. The function of electrical modulus complex has been examined from the point
of permittivity and impedance in order to clutch the contribution of the particle border on the relaxation mechanism
of the materials. It is established that the examined dielectric parameters strongly correlated with the voltage and
frequency. As a result, the changes in the dielectric parameters and electrical modulus due to the varying frequency were
described as the results of relaxation process, polarization and surface conditions. Furthermore, it could be stated that
the Alq3 material used in the interfacial layer is a useful material which could be used in addition to the conventional
materials.

Prediction of the standard enthalpy of formation (ΔfH0
298) of boron nitride nanocone (BNNCs) structures
with disclination angles 60°, 120°, and 180°is recommended to be performed by the isodesmic reaction approach. NH3 ,
BH3 , and N2 H4 were selected as key reference compounds. In order to calculate ΔfH0
298 of nanocones, we must first
calculate the enthalpies of nanocone rings at their apexes. For this purpose, ΔfH0
298 values of 40 different structures, such
as boron, nitrogen, and hydrogen compounds, have been calculated by combining Gaussian4 (G4) theory calculations
with the isodesmic and other balanced reactions approach. At each stage of the calculations, the previously estimated
enthalpies of formation of nanocones were used as reference points for new molecules in the isodesmic and other balanced
reactions. The results of enthalpies of formation of reference compounds were then used as reference values to estimate
the enthalpy of formation of rings of BNNCs at their apexes. Finally, enthalpies of formation of BNNCs with disclination
angles of 60°, 120°, and 180°and cone heights of 1–5 Å, 3–7 Å, and 4–8 Å were calculated. The results show that the
reactions are highly exothermic. An increase in cone height causes the enthalpy of formation of boron nitride nanocone
structures to become more negative.

Herein, the effect of γ quanta on electrophysical and photoelectric properties of ptype Pb1−x Mnx Se
epitaxial films obtained from the molecular cluster on the glass substrate by the method of condensation has been
investigated. It has been established that the acceptortype local levels with the ionization energy of 0.14 eV and 0.175
eV are generated, when ptype Pb1−x Mnx Se (x = 0.01) epitaxial films are irradiated by γ quanta at D >10 kGy doses.
The increase in the photoconductivity in the low temperature range 80180K is due to the discharge of 0.14eV level, but
the decrease in the rate of change of photocurrent in the high temperature range is due to the role of local level with
0.175 eV energy as a recombination center.

KNO scaling was put forward by Koba–Nielsen–Olesen in 1972 and then tested by various experiments up
to now. In this paper, the data on charged hadron multiplicity moments with KNO scaling of CHORUS and OPERA,
both of them emulsionbased neutrino experiments, are compared. The results are given in detail which is very useful
for tuning in MC event generators.

Velocity/energydependent potential to a parent nonlocal interaction is constructed for all partial waves by
Taylor series expansion method and the related s and pwave phase shifts for NN and αN systems are computed by
application of modified phase equation. Our phase shifts are in good agreement with standard data.

Recent developments in quantum computing and the growing interest in optomechanics and quantum optics
need platforms that enable rapid prototyping and scalability. This can be fulfilled by onchip integration, as we present
here. The different nanofabrication steps are explained, and our automated measurement setup is discussed. We present
an optoelectromechanical device, the Hresonator, which enables optomechanical experiments such as electrostatic
springs and nonlinearities and thermomechanical squeezing. Moreover, it also functions as an optomechanical phase
shifter, an essential element for our integrated quantum optics efforts. Besides this, the equivalent of a beam splitter in
photonicsthe directional coupleris shown. Its coupling ratio can be reliably controlled, as we show with experimental
data. Several directional couplers combined can realize the CNOT operation with almost ideal fidelity.

The pseudoscalar currentdelta transition form factors are calculated in the framework of relativistic baryon
chiral perturbation theory including order $\mathcal O(q^4)$. The complexmass scheme, which is suitable and welldefined for
unstable particles, is taken into account as a renormalization scheme. We discuss the low energy behavior of the
pseudoscalar $\widetilde g(Q^2)$ and $\widetilde h(Q^2)$ form factors and note that the momentum dependence of the form factors is dominated
by the pion pole contributions.
