Observations of the recent SN 1997cn in the elliptical galaxy NGC 5490 show that this objects closely resembles, both photometrically and spectroscopically, the faint SN Ia SN 1991bg. The two objects have similar light curves, which do not show secondary maxima in the near IR as normal type Ia supernovae. The host galaxy, NGC 5490, lies in the Hubble flow. Adopting for SN 1997cn a reddening

Evolutionary biologists have developed an excellent understanding of the selective factors that shape the way in which a given organism allocates resources to male and female offspring•a process called sex allocation (1_). Studies of sex allocation have provided explanations for a wide range of phenomena•for example, the variation among animals in the proportion of offspring that are male (sex ...

Abstract Background and Aims Synthetic data can be an effective supplement or alternative to real for the training of machine learning models. may also used evaluate new tools, develop educational curricula, remove undesirable biases in datasets. We aim four synthetic generation methods applied hypertension randomized clinical trial data. Method The Systolic Blood Pressure Intervention Trial (S...

KGaA, Weinheim 5490 wileyonlinelibrary.com recognized as one of the characteristic hallmarks in solid tumors with insuffi cient oxygen supply, directly contributing to the malignant properties of cancers. It is known that hypoxia plays essential roles in tumor angiogenesis and cancer metastasis. [ 4–6 ] Moreover, hypoxia would also lead to resistance to medica...

Gounaris and colleagues describe a previously unrecognized cross-talk between mast cells and Treg in colon adenomatous polyposis (Gounaris et al., Cancer Res 2009;69:5490-7). Adoptively transferred Treg suppress the focal mastocytosis that fosters tumor initiation and progression. In contrast, endogenous Treg, which abundantly infiltrate polyps, show proinflammatory activity under unknown micro...

The heart rate response to exercise was studied in 17 normal subjects before, during and after a 21-day Himalayan trek to 5490 m. The group were fitter before the trek when compared to normal subjects of a similar age (P less than 0.001) having a lower heart rate response to exercise for their lean body mass. The trek significantly increased the 'fitness' of the group as a whole (P less than 0....

Sheep face recognition models deployed on edge devices require a good trade-off between model size and accuracy, but the existing cannot do so. To solve above problems, this paper combines Mobilenetv2 with Vision Transformer to propose balanced sheep called MobileViTFace. MobileViTFace enhances model’s ability extract fine-grained features suppress interference of background information through...

Introduction Chronic Kidney Disease (CKD) has significant economic impact on both patients’ households and the country. Objectives To assess the out-of-pocket (OOP) expenditure of accessing health services among CKD patients in Anuradhapura District Methods This community based cross-sectional study included a representative sample of 1174 registered CKD patients from all 19 Medical Officer...

ABSTRACT We report on results of spectropolarimetry the afterglow long gamma-ray burst GRB 191221B, obtained with SALT/RSS and VLT/FORS2, as well photometry from two telescopes in MASTER Global Robotic Network, at MASTER-SAAO (South Africa) MASTER-OAFA (Argentina) stations. Prompt optical emission was detected by 38 s after alert, which dimmed a magnitude (white-light) ∼10–16.2 mag over period ...
