Variational quantum algorithms are augmented by an additional subroutine that efficiently detects signatures of barren plateaus -- unfavorable parameter regions prevent optimization due to vanishing gradients.

geomorphology, in some cases, provides a good platform for physical development of cities. however, physical development of cities, sometimes result in unsuitable and hazardous geomorphologic process and form. therefore, geomorphology of the region is of importance in physical planning and urban development. in this study, based on historical trends of expanding the boundaries of the malekan ci...

Executive summary: We scrutinized peer-reviewed literature, technical books, and key reports in order to detect any evidence for a differential ability between public and public lands to protect imperiled species in the United States. Limitations in data availability and/or in study scale limited our comparison mostly to certain contrasts of federal public versus mostly private lands. At a nati...

MAY I remind you of the old love story of Jacob, Leah and Rachel, the daughters of Laban. Jacob first married Leah and she bore him a succession of sons. Later he married her sister Rachel, and though it was Rachel that he really loved, she remaine...

Normalized Difference Vegetation Index (NDVI) is an index of greenness or photosynthetic activity in a plant. It technique obtaining various features based upon their spectral signature such as vegetation index, land cover classification, urban areas and remaining presented the image. The NDVI differencing method using Landsat thematic mapping images oli was implemented to assess chane from 200...

Cynodon dactylon (L.) Pers. (commonly known as bermudagrass) is a member of the family Poaceae. It C4 grass that can grow annually and perennially with clone reproduction seed-setting. not only used forage but also weed in many crops. grows along roadsides, barren lands, irrigated seacoasts, where soil salinity major problem. Although bermudagrass distributed worldwide, it shows limited growth ...

Abstract Commons provide many ecosystem services that support the livelihoods of billions around world. However, their contribution to people and economy are rarely estimated in economic terms. Here, we estimate land-based commons India, which cover 66.5 million hectares. We conducted a systematic literature review publications between 1990 2020 selected 161 peer-reviewed studies develop an val...

Siberian taiga is subject to intensive logging and natural resource exploitation, which promote the proliferation of informal roads: trails unsurfaced service roads neither recognized nor maintained by government. While transportation development can improve connectivity between communities urban centers, new also interfere with Indigenous subsistence activities. This study quantifies Land-Cove...

Until today, anti-microbial drugs have been the therapy of choice to combat bacterial diseases. Resistance against antibiotics is of growing concern in man and animals. Stress, caused by demanding environmental conditions, can reduce immune protection in the host, influencing the onset and outcome of infectious diseases. Therefore psychoneuro-immunological intervention may prove to be a success...
