Effects of the Nearest-Neighbour Coulomb Interactions on the Ground State of the Periodic Anderson Model

The magnetic and non-magnetic ground states of the periodic Anderson model with Coulomb interaction between $f$-electrons on the nearest-neighbour(NN) sites are investigated using a variational method, which gives exact calculation of the expectation values in the limit of infinite dimensions. It is shown that for a critical value of NN Coulomb interactions the magnetic ground state of the periodic Anderson model in the Kondo regime is unstable. Factors in terms of the physical processes responsible for instability of the magnetic ground state are also discussed. Our study indicates the importance of the NN Coulomb interactions for correlated two band models.Comment: RevTeX, 6 pages, 5 figures, to appear in Phys. Rev.

Unpacking qualitative methodology to explore experiences of mothers with children with autism spectrum disorder in the UAE: a thematic analysis inquiry

The current study provides a detailed description of the qualitative research design and methodology, used while exploring challenges and support structures experienced by expat mothers of children with Autism Spectrum Disorder (ASD) in the United Arab Emirates. In-depth, face-to-face, semi-structured interviews were administered with 17 mothers recruited using purposive and snowball sampling. Recurrent and relevant themes were generated using thematic analysis. Given there is a greater need for highlighting methodological rigor in qualitative research, we discuss steps such as a) using field knowledge to create an interview protocol, b) administering collaborative qualitative research, c) having strong eligibility criteria for participants, d) incorporating perspectives of multiple coders in the analytical process, e) being reflective and aware of one’s potential biases, f) enhancing interview protocol based on pilot interviews, g) and focusing on the quality of perspectives or information power instead of quantity of perspectives. Interpretation of findings and recommendation of evidence-informed guidelines incorporates strengths and limitations of the qualitative methodology utilized in the study

Religious factors affecting death anxiety in older adults practicing Hinduism

The aim of the study was to examine the influence of religion on death anxiety in older adults (N = 105) practicing Hinduism and visiting the Kumbh pilgrimage. Standardized questionnaires and brief interviews were administered in participants' native language. Pilgrims with higher religiosity had lower death anxiety compared to pilgrims with lower religiosity. Greater belief in the cycle of rebirth, an increased presence of meaning in life, and less continued search of meaning in life were significantly associated with lower death anxiety. The findings provide support for incorporating religious and spiritual awareness for older adults in community health settings

Exploring challenges and support structures of mothers with children with Autism Spectrum Disorder in the United Arab Emirates

Mothers with children with ASD, often being primary caregivers, experience high levels of parenting stress and hold essential information about their children's wellbeing. There is however lack of information about their experiences in the UAE. The study aims to explore challenges and support structures of mothers with children with ASD in the UAE. 17 expat mothers (Age = 33-58 years) with a child with ASD were interviewed about their experiences with diagnoses, therapeutic interventions, support networks, and the pandemic. Thematic analysis showed that initially most mothers struggled with accessing information to seek correct diagnoses, admission in mainstream international schools with typically developing children, and finding appropriate therapeutic services. Several mothers narrated experiences of not receiving optimum support from their partners, feeling rejected from extended family members, and facing hardships during the pandemic. Majority however appeared to be extremely satisfied with support groups where they felt heard and exchanged experience-based information crucial for children's wellbeing. Findings highlight the need for the government to facilitate centralized channels of information for expat parents with children with developmental disabilities, formalizing more support groups for mothers in the UAE, and increasing knowledge about autism to decrease biases.

Exploring media-induced secondary trauma during COVID-19: A global perspective

Aims: Given the risk of developing vicarious trauma through news media has increased during the pandemic, we explored risk factors associated with media induced secondary trauma, and its behavioral and psychological implications. Methods: An international study (N = 1066), with a diverse sample, was administered in July 2020. We used standardized and validated questionnaires to measure news consumption, media-related trauma, compliance, and paranoia. Results: Greater frequency of news consumption, accessing news via social media and WHO, and believing in conspiracy theories increased likelihood of developing media-induced secondary trauma. News related trauma was associated with greater compliance with safety measures and increased paranoid ideation. Media-trauma however exhibited a greater association with paranoia than compliance. Conclusion: Findings highlight the need to facilitate a collaborative intervention, with public, media houses, health safety officials, and social scientists to have a deeper understanding of potential psychological costs of news consumption patterns

Role of defects in transport through a quantum dot single electron transistor

The effect of a single dotlike defect on the transport through a quantum dot single electron transistor weakly coupled to external leads is studied. It is found that the conductance profile is changed significantly by the quantum mechanical tunneling between the dot and the defect and the interactions between them, both of which are dependent on the distance between the dot and the defect, as also by the morphology of the defect. In particular, we find that even a very small strength of interdot interaction has a major influence on the transport and must be taken into account in device fabrication

Novel forms of Paired-like homeodomain transcription factor 2 (PITX2): Generation by alternative translation initiation and mRNA splicing

<p>Abstract</p> <p>Background</p> <p>Members of the <it>Paired</it>-like homeodomain transcription factor (<it>PITX</it>) gene family, particularly <it>PITX1 </it>and <it>PITX2</it>, play important roles in normal development and in differentiated cell functions. Three major isoforms of PITX2 were previously reported to be produced through both alternative mRNA splicing (<it>PITX2A </it>and <it>PITX2B</it>) and alternative promoter usage (<it>PITX2C</it>). The proteins derived from these mRNAs contain identical homeodomain and carboxyl termini. Differences in the amino-termini of the proteins may confer functional differences in some contexts.</p> <p>Results</p> <p>Here, we report the identification of two novel PITX2 isoforms. First, we demonstrate that the <it>Pitx2c </it>mRNA generates two protein products, PITX2Cα and PITX2Cβ, via alternative translation initiation. Second, we identified a novel mRNA splice variant, <it>Pitx2b2</it>, which uses the same 5' splice donor in intron 2 as <it>Pitx2b </it>(hereafter referred to as <it>Pitx2b1</it>), but employs an alternative 3' splice acceptor, leading to an in-frame deletion of 39 base pairs relative to <it>Pitx2b1</it>. <it>Pitx2b2 </it>mRNA is expressed in both murine and human pituitary. The data show that in a murine gonadotrope cell line and adult murine pituitary what was previously thought to be PITX2B1 is actually PITX2Cβ, or perhaps PITX2B2. PITX2B1 is expressed at lower levels than previously thought. PITX2Cβ and PITX2B2 activate gonadotrope-specific gene promoter-reporters similarly to known PITX2 isoforms.</p> <p>Conclusion</p> <p>We have identified and characterized two novel isoforms of PITX2, generated by alternative translation initiation (PITX2Cβ) and alternative mRNA splicing (PITX2B2). These proteins show similar DNA binding and <it>trans</it>-activation functions as other PITX2 isoforms <it>in vitro</it>, though their conservation across species suggests that they may play distinct, as yet unidentified, roles <it>in vivo</it>.</p

Efektifitas Tanaman Serai (Andropogan Nardus L.) sebagai Tanaman Penolak Liriomyza Sp.(diptera : Agromizidae) pada Pertanaman Bawang Merah Lembah Pal

The research objective was to determine the effectiveness of the lemongrass plant (Andropogannardus L.) as a repellent pest plant against Liriomyza sp. At shallot cropping in Palu Valley. This study used a randomized block design within which treatments included planting lemongrass plant (PLP) at four weeks (PLP 4), two weeks before (PLP 2) and at the same time (PLP 0) of the shallot crop was planted, as well as control (with no lemongrass planting). Variables observed were the populations of adult Liriomyza sp. and the attack rate of Liriomyza sp. as well as the crop production. The results showed that five and six weeks after the shallots were planted, the population of adult and the attack rate of Liriomyza sp. were lower in the PLP 4 than in the PLP 2, PLP 0 and control treatments. The treatment plant as a crop repellent lemongrass does not affect the production of onion valley hammer.Attack rate, repellent plants, Liriomyza sp. imag
