1) The netCDF files created through post-processing of full model data in FORTRAN are shared in the /data/ directory. These file contains the zonal mean circulation statistics based on Gupta et al. (2020), age-of-air transport diagnostics based on Linz et al. (2021), and the novel \Gamma-\Theta circulation streamfunction introduced in this study. The /data/ directory also contains MATLAB .mat data files for the transport diagnostics obtained from WACCM. 150 days of actual GFDL-FV3 model data in the northern hemisphere, between 0.1 hPa-500 hPa pressure levels is also provided to support external computations and validation.
2) The Jupyter notebook used for final computation and figures production is provided in .ipynb, .html and .pdf formats in /code/. All the files referred to in the notebook are stored in the /data/ directory.

Early Buddhist architecture of Bengal: morphological study on the vihāra of c. 3rd to 8th centuries
No full textThis dissertation examines the evolution of early Buddhist architectural forms of Bengal, specifically its vihāra and shrine structures. In general, this research explores Gupta and post-Gupta (c. third to eighth centuries AD) vihāra architecture of Bengal, where the primary focus is on the Buddhist shrine architecture constructed during this period. There is a preconception amongst historians that the period between the Gupta and the Pāla periods was characterized by disorder and chaos, commonly known as the period of Matsyanyayam. This is the reason why discussions on the architectural history of Bengal have generally commenced from the Pāla period (c. 750 AD onwards). Analyzing extant and new evidences this study argues that the Buddhist architecture of Bengal thrived during the intervening period, albeit under the patronage of local kings and rulers. In the field of art and sculpture it is accepted that Buddhist Pāla art was a continuation of previous Gupta art forms, where post-Gupta period acted as the transition or a bridge. Following this general pattern, as this thesis argues, the rectangular Gupta shrine plan takes a mature cruciform shape during the Pāla period through a complex morphological development. The nature of Buddhist shrine architecture in Bengal during the early Gupta, later Gupta, and post-Gupta periods is described in the light of analyzed archaeological findings and architectural trends

On the aberration–retardation effects in pulsars
No full textThe magnetospheric locations of pulsar radio emission region are not well known. The actual form of the so-called radius-to-frequency mapping should be reflected in the aberration-retardation (A/R) effects that shift and/or delay the photons depending on the emission height in the magnetosphere. Recent studies suggest that in a handful of pulsars the A/R effect can be discerned with respect to the peak of the central core emission region. To verify these effects in an ensemble of pulsars, we launched a project analysing multifrequency total intensity pulsar profiles obtained from the new observations from the Giant Meterwave Radio Telescope (GMRT), Arecibo Observatory (AO) and archival European Pulsar Network (EPN) data. For all these profiles, we measure the shift of the outer cone components with respect to the core component, which is necessary for establishing the A/R effect. Within our sample of 23 pulsars, seven show the A/R effects, 12 of them (doubtful cases) show a tendency towards this effect, while the remaining four are obvious counterexamples. The counterexamples and doubtful cases may arise from uncertainties in the determination of the location of the meridional plane and/or the core emission component. Hence, it appears that the A/R effects are likely to operate in most pulsars from our sample. We conclude that in cases where those effects are present the core emission has to originate below the conal emission region
Phanerotoma andamanensis Gupta
No full textPhanerotoma andamanensis Gupta & van Achterberg sp. nov. (Figs A–N) Measurements: Length of body in dorsal view 4.0 mm (holotype, Fig. A); 3.7 (paratype, Fig. G); 3.2 mm (paratype, male, Fig. J); antenna 3.1 mm (paratype, female) and fore wing 2.9 (holotype) or 2.5 mm (paratype, female). Female. Colour: Yellowish brown. Basal five segments and pedicel of antenna yellowish, remainder of antenna brown. Eyes and stemmaticum black. Pronotum pale testaceous; T 1 and T 2 pale testaceous; T 3 yellowish brown laterally, but medio-longitudinal third black; T 1 with H shaped mark medially. Tip of mandible dark brown. Pterostigma dark brown without distinct pale basal spot, only somewhat paler basally than medially; ocelli yellow; hind tibia medially pale yellow. Head (Fig. B): Width 1.3 times median length in frontal; antenna with 23 segments and 1.1 times as long as fore wing; area of stemmaticum punctate (Fig. D); OOL: diameter of posterior ocellus: POL= 6: 2: 1; vertex transversely rugose with fine granulate background anteriorly, setose; temple rugose; face rugose with median ridge and setose; clypeus smooth medially, shiny and setose; malar space rugose, lower tooth of mandible 0.25 times as long as apical tooth (Fig. C). Mesosoma (Fig. E): 1.4 times as long as wide; sides of pronotum coarsely crenulate with median depression dorsally; mesoscutum granulose-reticulate, setose; notauli distinct and foveate anteriorly, absent posteriorly; scutellar sulcus wide and with 9 crenulae; scutellum finely punctate and setose; metanotum with median ridge; propodeum coarsely reticulate rugose with distinct transverse carina below the median line, median carina absent, median areola just above transverse carina (open anteriorly). Fore wing 3.2 times as long as wide; length of 1 -R 1 1.5 times pterostigma; r issued much beyond middle of pterostigma; 2 -SR slightly sinuate; 3 -SR and SR 1 slightly curved; 2 -SR+M longitudinal; parastigma large and dark brown pigmented; m-cu interstitial; vein 1 -CU 1 0.8 times as long as vein 2 -CU 1; 3 -SR = 0.35 times as long as 1 -R 1 and 5.6 times r; r = 0.3 times as long as width of pterostigma; pterostigma 3 times longer than wide; 1 -R 1 = 1.5 times longer than pterostigma; inner mid tibial spur 0.6 times mid basitarsus; hind coxa finely punctate; hind femur 3.7 times its width. Metasoma (Fig. F): Oval in dorsal view and 1.8 times as long as wide, 1.2 times as long as mesosoma; first –second tergites longitudinally spaced rugose with some interconnections, second suture sinuate dorsally; third tergite longitudinally reticulate-rugose and truncate medio-posteriorly, its medial length 1.6 times medial length of second tergite, lateral lamella not protruding latero-apically; ovipositor exerted (0.16 mm in lateral view) and setose; exerted part of sheath 0.14 times as long as hind tibia. Male (Fig. J ): Similar to female except for smaller size and T 3 completely black (Fig. M). Note. The new species differs from all described Oriental species by the combination of the dark brown vein 1 - M and 1 -R 1 of the fore wing, the median third of the third tergite of female dark brown and contrasting with yellowish brown lateral parts and the rather long vein 1 -CU 1 of the fore wing. In the key to Indian species by Sheeba & Narendran (2008) the new species runs to P. buchneri Fahringer, 1932, from NE. India because of its size and the venation and to P. agarwali Varshney & Shujauddin, 1999, from N. India. P. buchneri has a rather pale 1 - R 1 (darkened in P. andamanensis), the pterostigma largely pale brown (dark brown), vein 1 -CU 1 of the fore wing about 0.7 times vein 2 -CU 1 (0.8 times), the hind tibia with dark brown subbasal patch (absent), the propodeum darkened (brownish yellow), the third tergite apically dark brown and anteriorly yellowish brown (laterally brownish yellow and medially dark brown) and T 1 posteriorly and T 2 medially distinctly brownish yellow pigmented (largely unpigmented). P. agarwali Varshney & Shujauddin, 1999 (a junior synonym of P. s y l ep t ae Zettel, 1990, syn. nov.) differs by having the third tergite medio-apically concave and lateral lamella somewhat protruding (truncate and lamella not protruding); vein 1 -CU 1 about 0.5 times as long as vein 2 -CU 1 (incorrectly depicted in original description of P. agarwali; 0.7 times in P. andamanensis); the pterostigma brown (dark brown) and the third tergite yellowish brown (median third dark brown and remainder yellowish brown).
