The emerging moiré superstructure of twisted transition metal dichalcogenides (TMDs) leads to various correlated electronic and optical properties compared to those of twisted bilayer graphene. In such a versatile architecture, phonons can also be renormalized and evolve due to atomic reconstruction, which, in turn, depends on the twist angle. However, observing this reconstruction and its relationship to phonon behavior with conventional, cost-effective imaging methods remains challenging.

We aimed to explore the experiences of caregivers of persons with schizophrenia (PwS) to comprehend the emotional challenges and other burdens and coping strategies utilized.
Methods: We subscribed to a phenomenological approach and interviewed nine caregivers in-depth.
Collective spin-wave excitations, magnons, are promising quasi-particles for next-generation spintronics devices, including platforms for information transfer. In a quantum Hall ferromagnets, detection of these charge-neutral excitations relies on the conversion of magnons into electrical signals in the form of excess electrons and holes, but if the excess electron and holes are equal, detecting an electrical signal is challenging. In this work, we overcome this shortcoming by measuring the electrical noise generated by magnons.

However, women facing challenges in conceiving often grapple with emotional distress, including depression and anxiety. The connection between psychological elements (stress, anxiety, and depression) and infertility is complex, influenced by multiple factors, and bidirectional.

We defined psychotherapy as an intervention aimed at treating mental disorders using "talk," which, in a professional medical setting, along with the therapeutic relationship, acquires medicinal value. Besides manual searches in three leading Indian psychiatry journals, we conducted digital searches in PubMed, Google Scholar, and Scopus databases.

Our measurements revealed that the nonlocal resistance (R_{NL}) surpassed the expected classical Ohmic contribution by a factor of at least 2 orders of magnitude. Through scaling analysis, we found that the nonlocal resistance scales linearly with the local resistance (R_{L}) only when the D exceeds a critical value of ∼0.

Background And Objectives: With the aging of Indians and the cultural context of family care, faith-based ashrams are a possible middle way for older adult care for strained families. Religiosity is multidimensional, but it is unclear how its different dimensions relate to coping. This exploratory study investigates the profile of residents living in a faith-based ashram of Haridwar, a pilgrimage town in Northern India.

To determine the topological quantum numbers of fractional quantum Hall (FQH) states hosting counter-propagating (CP) downstream (N) and upstream (N) edge modes, it is pivotal to study quantized transport both in the presence and absence of edge mode equilibration. While reaching the non-equilibrated regime is challenging for charge transport, we target here the thermal Hall conductance G, which is purely governed by edge quantum numbers N and N. Our experimental setup is realized with a hexagonal boron nitride (hBN) encapsulated graphite gated single layer graphene device.

We investigate the tuning of the thermal conductivity with the twist angle between two layers and found a decreasing trend of with the increase in the lattice constant of the moiré superlattice. The thermal conductivity at twist angle = 21.

The presence of "upstream" modes, moving against the direction of charge current flow in the fractional quantum Hall (FQH) phases, is critical for the emergence of renormalized modes with exotic quantum statistics. Detection of excess noise at the edge is a smoking gun for the presence of upstream modes. Here, we report noise measurements at the edges of FQH states realized in dual graphite-gated bilayer graphene devices.

However, the influence on attitudes and lifestyle due to lockdown amidst the coronavirus disease 2019 (COVID-19) pandemic has been poorly understood. The present study aimed to investigate the influence on attitudes and lifestyle due to lockdown amidst the COVID-19 pandemic among Bangladeshi residents.

Robust quantized values of charge and thermal conductances dictated by bulk topology appear when equilibration processes become dominant. We report on measurements of electrical and thermal conductances of integer and fractional QH phases, realized in hexagonal boron nitride encapsulated graphite-gated bilayer graphene devices for both electron and hole doped sides with different valley and orbital symmetries.

We examined patients with psoriasis and dermatitis for excessive alcohol consumption using the Alcohol Use Disorders Identification Test (AUDIT). For this cross-sectional, observational study, 385 patients of both genders, aged ≥18 years, who were diagnosed with either psoriasis or dermatitis, were recruited.
