The frequency of LI is high and comparable among IBS patients and HS from northern India. Patients with IBS more often reported symptoms following lactose ingestion despite levels of breath hydrogen being similar to HS. The frequency of LI in patients with IBS-D was comparable to that in patients with other types of IBS. Self-reported milk intolerance has poor sensitivity in detecting LI.

We report GPS measurements of postseismic deformation from 22 campaign‐mode and one continuous GPS sites in the Andaman‐Nicobar region following the great Sumatra‐Andaman earthquake of 26 December 2004. Large horizontal displacements toward west to southwest, varying in magnitude from 10 to 40 cm, and with uplift reaching 16 cm, occurred in the region in the first year after the earthquake. The observed motion decreased logarithmically in the subsequent year. We suggest that in the Andaman region, frictional afterslip occurred farther downdip of the coseismic rupture, while in the Little Andaman and Nicobar regions, the coseismic rupture and afterslip patch partly overlapped. The afterslip was mostly aseismic and did not contribute to the aftershocks. The aftershocks and postseismic displacements appear to follow a similar relationship, although with different decay times. The temporal dependence of the two differs only by a term linear in time. Thus the temporal evolution of the afterslip seems to be consistent with a mechanism governed by frictional afterslip. Available rates of interseismic and postseismic deformation and coseismic static offsets allow us to approximately estimate a return period of about 400 years for great earthquakes in the Andaman region.

Summary The tantalum‐based double perovskites Ba2MTaO6 (M = Mn, Cr) are studied to understand the effect of pressure on structural, electronic, magnetic, thermodynamic, and thermoelectric properties by means of density functional theory. Ba2MTaO6(M = Mn, Cr) perovskites' own maximum stability in ferromagnetic phase with calculated high magnetic moments of 4.02 and 3.0 μB at zero pressure. Ba2MTaO6 (M = Mn, Cr) perovskites display complete spin polarization, ensuing the half metallic behavior. Effect of high pressure on the electronic structure and magnetism was also studied. The compounds have wide band gap that varies from 2.63 to 2.56 eV as the pressure increases from 0 to 25 GPa in Ba2CrTaO6, while as in Ba2MnTaO6 band gap varies from 2.24 to 1.95 eV as the pressure increase from 0 to 25 GPa. The magnetic moment also shows a decreasing inclination with increase in pressure in both compounds. Also, we calculated the heat capacities, thermal expansion coefficients, Debye temperature and Grüneisen parameter by using the Debye model. Boltzmann's theory was employed to perform post DFT treatment to investigate the thermoelectric properties of the compounds.

In the hunt for novel materials, we present self-consistent ab initio simulations of the structural stability, electronic profile, and transport properties of f-electron-based RbMO3 (M = Np, Pu) perovskites within the context of density functional theory. The structural stability and thermodynamic concerns are fixed by relaxing the crystal structure and computing the energy of formation, respectively. Furthermore, the decisive physical features of given materials have been outlined using the optimised lattice constant retrieved from structural optimizations. The ground state magnetic phase stability is ascertained by minimizing Birch Murnaghan's equation of state in distinct magnetic phases, upholding the ferromagnetic phase (FM) as the ground state magnetic phase, which is further backed by positive Curie Wiess constant values. To specify the electronic structure, a mix of the two approximations GGA and GGA + mBJ has been executed, both of which assert the half-metallic character, culminating in 100% spin polarisation at the Fermi level. The study of the magnetic moment and Curie temperature of each material has further been assessed in the present study. Apart from half-metallicity, the thermoelectric response of the present materials is quantified by exploring the chemical potential dependency of several transport parameters like Seebeck coefficient, electrical and thermal conductivity, power factor, etc. Moreover, the thermoelectric competence has been tested using a zT calculation, adapting values of 1.01 and 0.987 at 300 K for RbNpO3 and RbPuO3, respectively. The high electronic zT at encompassing temperatures uncovers the significant utility of these materials in both low-and high-temperature thermoelectric device applications. In essence, the comprehensive survey of these alloys could certainly open up their possibilities in spintronics, thermoelectric, and solid-state (RTG) device applications.
