We report on a study of the surface density of Extremely Red Objects (EROs) in the fields of 13 radio-loud quasars at 1.8 < z < 3.0 covering a total area of 61.7 arcmin. There is a large variation in the ERO surface density from field to field, and as many as 30–40 % of the fields have roughly 4–5 times more EROs than what is expected from a random distribution. The average surface density exce...

Populus euphratica is an important tree species in desert ecosystems. The protection and restoration of natural forests requires accurate positioning information. use Sentinel-2 images to map the distribution at a large scale faces challenges associated with discriminating between Tamarix chinensis. To address this problem, study selected Daliyabuyi Oasis hinterland Taklimakan Desert as site so...

background : sentinel lymph node biopsy is used as an accurate staging procedure to detect early breast cancer. several studies have documented that sentinel lymph node biopsy can accurately determine the status of axillary nodes. sentinel node biopsy offers the advantage of accurately staging the axilla and eliminating the need for a full axillary dissection for patients who have a negative se...

in this report, we present a facile approach for the synthesis of luminescent cds and cds:mn+2 nanocrystals by reaction of cdso4 and na2s2o3 in the presence of thioglycerol (c3h8o2s) as capping agent. the influence of various experimental variables including, ph values and percentage of dopant, on the growth rate and optical properties of the obtained cds nanocrystals has been systematically in...

Synthetic aperture radar (SAR) images are subject to prominent speckle noise, which is generally considered a purely multiplicative noise process. In theory, this multiplicative noise is that the ratio of the standard deviation to the signal value, the “coefficient of variation,” is theoretically constant at every point in a SAR image. Most of the filters for speckle reduction are based on this...

Active-optical sensor readings from an N non-limiting area standard established within a farm field are used to predict yield in the standard. Lower yield predictions from sensor readings obtained from other parts of the field outside of the N non-limiting standard area indicate a need for supplemental N. Active-optical sensor algorithms for predicting corn (Zea mays, L.) yield to direct in-sea...

Previously in class we proved that if we color the edges of K6 using blue or red color, then either there is a blue K3 or a red K3 as a subgraph. Here Kn is the complete graph (every pair of vertices are connected) on n vertices. We can generalize the above concept and ask, are there complete graphs for which any 2-coloring gives rise to either a blue Kk or a red Kl. It has been shown that ther...

Background and Aim: The proportion of smile is a useful tool for creating geometric smiles which are a critical aspect in esthetic dentistry. The aim of this study was to determine the effect of lip line position on acceptable Recurring Esthetic Dental (RED) proportion among lay people. Materials and Methods: A photograph of pose smile of a young female was taken. The position of the lip was c...

Herein, we report a case of sentinel lymph node mapping in a uterine cervix cancer patient, referring to the nuclear medicine department of our institute. Lymphoscintigraphy images showed inappropriate intra‐cervical injection of radiotracer. Blue dye technique was applied for sentinel lymph node mapping, using intra‐cervical injection of methylene blue. Two blue/cold sentinel lymph nodes, with...
