Fostering equality in education: The blockchain business model for higher education (BBM-HE)
This paper seeks to address which business model in higher education that fosters SDG 4, is adequate for the post-pandemic period. To that end, it introduces the “Blockchain Business Model for Higher Education” (BBM-HE) and a transformed business model canvas framework based on existing literature, concepts, theories and findings relating to most of the pressing issues in higher education from the present study. To determine these issues, secondary data is used in the qualitative research design by applying inductive content analysis techniques to online reports. The originality of this study lies in the “adaptive” perspective to the requirements of the post-pandemic higher education landscape, which consists of modifications to the core elements of higher education, the integration of blockchain technology into the entire system, and a stronger approach to sustainability practice through sustainability tokens. The envisaged model sets out to provide a roadmap for all stakeholders, but most importantly, “decentralized” higher education institutions of the future and the “employable skills-seeking” proactive students all over the world, as opposed to the former “solely degree-focused and affluent” consumers of educational offerings. This study contributes to higher education literature in terms of business models, blockchains, pandemics, and sustainability.WOS:000768267400001Scopus - Affiliation ID: 60105072Social Sciences Citation IndexQ2 - Q3ArticleUluslararası işbirliği ile yapılmayan - HAYIRMarch2022YÖK - 2021-22Mar
Quantal description of nucleon exchange in stochastic mean-field approach
Nucleon exchange mechanism is investigated in central collisions of symmetric
heavy-ions in the basis of the stochastic mean-field approach. Quantal
diffusion coefficients for nucleon exchange are calculated by including
non-Markovian effects and shell structure. Variances of fragment mass
distributions are calculated in central collisions of Ca +
Ca, Ca + Ca and Ni + Ni systems
Constraints on Dark Photon from Neutrino-Electron Scattering Experiments
A possible manifestation of an additional light gauge boson , named
as Dark Photon, associated with a group is studied in neutrino
electron scattering experiments. The exclusion plot on the coupling constant
and the dark photon mass is obtained. It is shown
that contributions of interference term between the dark photon and the
Standard Model are important. The interference effects are studied and compared
with for data sets from TEXONO, GEMMA, BOREXINO, LSND as well as CHARM II
experiments. Our results provide more stringent bounds to some regions of
parameter space.Comment: 22 pages, 6 figures, 2 tables, text improved, fig.6 updated,

Signatures for doubly-charged Higgsinos at colliders
Several supersymmetric models with extended gauge structures predict light
doubly-charged Higgsinos. Their distinctive signature at the large hadron
collider is highlighted by studying their production and decay characteristics.Comment: 3 pages, 4 figures, Latex. Submitted for SUSY 2008 proceeding
CP Asymmetry in Charged Higgs Decays in MSSM
We discuss and compare the charge-parity (CP) asymmetry in the charged Higgs
boson decays H -> \bar{u}_i d_j for the second and third generation quarks in
the minimal supersymmetric standard model. As part of the analysis, we derive
some general analytical formulas for the imaginary parts of two-point and
three-point scalar one-loop integrals and use them for calculating vectorial
and tensorial type integrals needed for the problem under consideration. We
find that, even though each decay mode has a potential to yield a CP asymmetry
larger than 10%, further analysis based on the number of required charged Higgs
events at colliders favors the \bar{t}b, \bar{c}b, and \bar{c}s channels, whose
asymmetry could reach 10-15% in certain parts of the parameter space.Comment: 25 pages, 9 figures. Discussion about charged Higgs observability

CP Asymmetry in Charged Higgs Decays to Chargino-Neutralino
We analyze the charge-parity (CP) asymmetry in the charged Higgs boson decays
to chargino-neutralino pairs, H^- -> chargino_i + neutralino_j. We show first
that these modes have a large branching ratio for m_H^- > 600 GeV. We use
Cutkosky rules to obtain the analytical formulas needed for the evaluation of
the asymmetry under consideration. We then calculate the CP asymmetry in
chargino-neutralino decays by including supersymmetric mass bounds, as well as
constraints from b -> s gamma, (g-2)_mu, Delta\rho and electric dipole moments.
Finally, we discuss observability of the asymmetry at the LHC by calculating
the number of required charged Higgs events to observe the asymmetry for each
decay channel. We show that the inclusion of constraints considerably reduces
the projected CP asymmetry, and that the optimal channel for observing the
asymmetry is H^- -> chargino_1 + neutralino_2.Comment: 23 pages, 8 figures, one tabl
Multi-domain active sound control and noise shielding
This paper describes an active sound control methodology based on difference potentials. The main feature of this methodology is its ability to automatically preserve “wanted” sound within a domain while canceling “unwanted” noise from outside the domain. This method of preservation of the wanted sounds by active shielding control is demonstrated with various broadband and realistic sound sources such as human voice and music in multiple domains in a one-dimensional enclosure. Unlike many other conventional active control methods, the proposed approach does not require the explicit characterization of the wanted sound to be preserved. The controls are designed based on the measurements of the total field on the boundaries of the shielded domain only, which is allowed to be multiply connected. The method is tested in a variety of experimental cases. The typical attenuation of the unwanted noise is found to be about 20 dB over a large area of the shielded domain and the original wanted sound field is preserved with errors of around 1 dB and below through a broad frequency range up to 1 kHz.

Chromogenic and Fluorogenic Sensing of Biological Thiols in Auqeous Solutions Using BODIPY-Based Reagents
Cataloged from PDF version of article.udicious design of BODIPY dyes carrying nitroethenyl substituents in conjugation with the BODIPY core yields dyes that respond to biological thiols by both absorbance and emission changes. Incorporation of solubilizing ethyleneglycol units ensures water solubility.
