Theoretical analysis of two-color ghost interference
No full textRecently demonstrated ghost interference using correlated photons of different
frequencies, has been theoretically analyzed. The calculation predicts an interesting
nonlocal effect: the fringe width of the ghost interference depends not only on the
wave-length of the photon involved, but also on the wavelength of the other photon with
which it is entangled. This feature, arising because of different frequencies of the
entangled photons, was hidden in the original ghost interference experiment. This
prediction can be experimentally tested in a slightly modified version of the
experiment
Exploring the Role of UX Influencing Factors in Virtual Reality for Natural Hazards Prepardness: A Disign-Based Approach
No full textClimate change is one of the major challenges of our time, and its complexity makes finding innovative solutions challenging. One of the ways that climate change poses a challenge is by reshaping the earth’s natural ecosystem and increasing the frequency and severity of Natural Hazards (NH), such as floods and landslides, that affect millions of people and cause substantial losses. One potential solution is to leverage digital transformation and explore the use of narratives and immersive media technologies, such as virtual reality (VR), to communicate scientific information about NH and enable change. However, traditional methods of communication, such as reports and maps, may not be sufficient or accessible to a broader audience. Therefore, there is a need to develop transformative and immersive experiences that can facilitate the comprehension and communication of scientific information about NH.
This research project created immersive and engaging Virtual Reality Environments (VRE) that communicated NH using digital transformation technology as part of an interdisciplinary project called World of Wild Waters (WoWW). VR offered a unique opportunity to create digital twins of NH by integrating numerical simulations of geophysical phenomena that users could explore and manipulate. However, to create engaging VR, it was crucial to explore the factors that influenced User Experience (UX) within VR.
To address this challenge, the work adopted a design-based research (DBR) approach, which consisted of three iterative cycles, each addressing a specific objective. DBR Cycle 1 explored the factors that could enhance user-perceived quality in Immersive Media Experiences (IME). A conceptual framework was formulated by integrating Interactive Digital Narratives (IDN) as an important dimension to be investigated in VR. Based on the proposed framework, a case study was designed to explore the role of IDN and its impact on UX in VR.
DBR Cycle 2 evaluated the impact of affordances on user-perceived experiences in VR. It developed a VR that integrated wayfinding cues as affordances for NH preparedness. The VR prototype implemented three VREs with several types of wayfinding cues: no cues, static cues, and dynamic cues, and it evaluated the psychological and psychometric effects of wayfinding cues on UX within the VR.
DBR Cycle 3 designed and evaluated a VR framework for visualizing numerical simulations of geophysical flows (i.e., floods) to enhance risk communication of NH in VR. We implemented a VR prototype that used the VR framework to visualize and interact with simulations of NH. Furthermore, DBR cycle 3 evaluated the influence of emotions and identity on UX in VR. The research demonstrated the novelty and originality of using VR to enhance the understanding and communication of NH and foster risk awareness and resilience among diverse audiences and stakeholders.
The results showed how UX influencing factors such as IDN, affordances, emotions, and identity enhanced the VR experience, thus contributing to the advancement of knowledge and practice in the fields of VR, UX, and NH. Moreover, this research provided insights and guidelines for creating effective and engaging VR for communicating complex and uncertain scientific information about NH
Distinguishing between Dirac and Majorana neutrinos using temporal correlations
No full textIn the context of two flavour neutrino oscillations, it is understood that
the mixing matrix is parameterized by one angle and a Majorana
phase. However, this phase does not impact the oscillation probabilities in
vacuum or in matter with constant density. Interestingly, the Majorana phase
becomes relevant when we describe neutrino oscillations along with neutrino
decay. This is due to the fact that effective Hamiltonian has Hermitian and
anti-Hermitian components which cannot be simultaneously diagonalized
(resulting in decay eigenstates being different from the mass eigenstates). We
consider the symmetric non-Hermitian Hamiltonian describing two
flavour neutrino case and study the violation of Leggett-Garg Inequalities
(LGI) in this context for the first time. We demonstrate that temporal
correlations in the form of LGI allow us to probe whether neutrinos are Dirac
or Majorana. We elucidate the role played by the mixing and decay parameters on
the extent of violation of LGI. We emphasize that for optimized choice of
parameters, the difference in () for Dirac and Majorana case is

The impact of COVID-19 on pharmacy education in Saudi Arabia
No full textAbstract: In late 2019, the first COVID-19 case was announced. Subsequently, numerous other instances were found all around the world. On March 2, 2020, the first case was reported in Saudi Arabia. The Saudi government has taken several precautions to stop the spread of this pandemic sickness. Closing public and private schools and universities and moving educational activity to online platforms were two of these approaches. whether they are the 21 public pharmacy schools in Saudi Arabia or the. These abrupt transitions had an impact on 8 people, and depending on their level of preparedness, they responded differently. Here, we discuss the elements of the pharmacy school curriculum, including classroom instruction, laboratory work, and experiential learning, based on our experience at King Saud University.

Evaluation of cellobiose dehydrogenase and laccase containing culture fluids of Termitomyces sp. OE147 for degradation of Reactive blue 21
No full textAbstractThis study evaluates culture filtrate, rich in cellobiose dehydrogenase and laccases, of Termitomyces sp. OE 147, in decolouration and degradation of Reactive blue (RB) 21. About 35% decolouration was achieved at low volumes of the culture supernatant without addition of external redox mediators. An optimized dye to culture fluid ratio (75ppm: 0.1ml) at a pH of 4–5 resulted in removal of colour by 60%. The degradation products of RB21 were analysed by Electron Spray Ionization-Mass Spectrometry and several small molecules (ofm/z 106–199) were detected. These were concluded to be o-Xylene, 2,3-Dihydro-1H-isoindole, Isoindole-1,3-dione, 2,Benzenesulfonyl-ethanol, (4-Hydroxy-phenyl)-sulfamic acid, 2,3-Dihydro-1H-isoindole-5-sulfonic acid and proposed to result from joint action of cellobiose dehydrogenase, laccase, peroxidases and unidentified oxidoreductases present in the culture fluids. Based on the products formed and the known reactions of these enzymes, a degradation pathway was proposed for RB21. The culture fluid was also effective in decolouration (by about 50%) and detoxification (by ∼25%) of the combined effluent collected from a local mill indicating a treatment process that bypasses use of H2O2 and toxic mediators
