Given a single view of an object, humans can readily recognize that object from other views that preserve the parts in the original view. Empirical evidence suggests that this capacity reflects the activation of a viewpoint-invariant structural description specifying the object's parts and the relations among them. Thi... |
Background: Metabolic disorders (i.e., metabolic syndrome, type 1 and type 2 diabetes, and polycystic ovarian syndrome; PCOS) are rising to epidemic proportions. Many severe symptoms and impaired behaviors are associated with metabolic disorders, but often overlooked is the relationship between metabolic disorders and ... |
CD100 represents the first semaphorin described in the immune system. It is expressed as a 300-kDa homodimer at the surface of most hematopoietic cells, but is also found in a soluble form following a proteolytic cleavage upon cell activation. We herein established that soluble CD100 (sCD100) impaired the migration of ... |

Automated program repair (APR) is a promising approach to automatically fixing software bugs. Most APR techniques use tests to drive the repair process; this makes them readily applicable to realistic code bases, but also brings the risk of generating spurious repairs that overfit the available tests. Some techniques a... |
In this paper, we propose a comparative study to check the matrix effect on the extraction of three chlorophenols, 2,4,6-trichlorophenol (TCP), 2,3,4,6-tetrachlorophenol and pentachlorophenol, direct precursors of 2,4,6-trichloroanisole, in synthetic and commercial wines (white and red wines). A rapid, simple and sensi... |
Abstract Many species of parasitic Hymenoptera inbreed regularly and do not suffer inbreeding depression. However, these inbreeding species could experience outbreeding depression due to the breakup of coadapted gene complexes. We measured the effects of outbreeding on three fitness components of the ectoparasitoid Nas... |

OBJECTIVE |
Computer-aided evaluation (CAE) programs for breast MRI provide automated lesion kinetic information. The CAE kinetic parameters that best predict malignancy have not been established. We compared three CAE kinetic features of suspicious breast MRI lesions to determine associations with benign or malignant outcomes. |
MATERIALS AND METHODS |
From 1,532 MRI examinations, all suspicious breast lesions initially detected with MRI and having CAE kinetics and subsequent biopsy were identified. Three CAE variables were compared for benign and malignant lesions: initial phase peak enhancement (greatest percentage signal intensity increase on first contrast-enhanc... |
RESULTS |
One hundred twenty-five lesions (42 malignant, 83 benign) comprised the analysis set. There were no significant differences in initial peak enhancement (p = 0.28) or delayed kinetics categorized by largest percentage enhancement types (p = 0.39) between benign and malignant lesions. There was a significant difference i... |
CONCLUSION |
Of CAE kinetics analyzed, only delayed enhancement categorized by most suspicious type was significantly different between benign and malignant lesions. This supports the American College of Radiology BI-RADS Breast MRI Lexicon recommendation to report the "worst looking" kinetic curve.Strategic Orientation and Innovat... |

PURPOSE |
To investigate the suitability of the microDiamond detector (mDD) type 60019 (PTW-Freiburg, Germany) to measure the anisotropy function F(r,ϑ) of High Dose Rate (HDR) 192 Ir brachytherapy sources. |
METHODS |
The HDR 192 Ir brachytherapy source, model mHDR-v2r (Elekta AB, Sweden), was placed inside a water tank within a 4F plastic needle. Four mDDs (mDD1, mDD2, mDD3, and mDD4) were investigated. Each mDD was placed laterally with respect to the source, and measurements were performed at radial distances r = 1 cm, 3 cm and 5... |
RESULTS |
At 1 cm, the differences between measurements and MC simulations ranged from -0.8% to +0.8% for ϑ = 0° and from -2.1% to +2.3% for ϑ ≠ 0°. At 3 cm and 5 cm, the differences ranged from +1.4% to +3.9% for ϑ = 0°, and from -0.4% to +2.9% for ϑ ≠ 0°. All differences were within the uncertainties (k = 2). At small angles, ... |
CONCLUSIONS |
A reproducible method and experimental setup were presented for measuring and validating F(r,ϑ) of an HDR 192 Ir brachytherapy source in a water phantom using the mDD. The phantom-effect and the volume-averaging need to be taken into account, especially for the smaller distances and angles. Good agreement to CON F(r,ϑ)... |
