This paper derives explicit expressions for the asymptotic variances of the maximum likelihood and continuously updated GMM estimators under potentially misspecified models. The proposed misspecification-robust variance estimators allow the researcher to conduct valid inference on the model parameters even when the model is rejected by the data. Although the results for the maximum likelihood e...

Room temperature two-dimensional (2D) ferromagnetism is highly desired in practical spintronics applications. Recently, 1T phase CrTe2 (1T-CrTe2) nanosheets with 5 and thicker layers have been successfully synthesized, which all exhibit the properties of ferromagnetic (FM) metals Curie temperatures around 305 K. However, whether therein can be maintained when continuously reducing nanosheet’s t...

Aqueous extract and volatile oil were obtained from Miliusa tomentosa by using soxhlet extractor and hydro distillation with a Clevenger-type apparatus respectively. The extract and volatile oil both were screened for Antimicrobial activity against different bacteria (Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Klebsiella pncumoniae, Pseudomonas aeruginosa, Bacillus pumilis) and...

BACKGROUND This study aimed to investigate the effect of strenuous exercise on β-endorphine (β-END) level in fibromyalgia (FM) patients compared to healthy subjects. METHODS We enrolled 30 FM patients and 15 healthy individuals. All study participants underwent a treadmill exercise test using modified Bruce protocol (M.Bruce). The goal of the test was achieving at least 70% of the predicted m...

Background: Dislocation after total hip arthroplasty is a common complication and partially based on impingement. Questions/purposes: (1) The purpose of this study was to investigate the angle between anterior and posterior impingement in current hip cup designs. (2) Furthermore, the aim was to design a model of an acetabular cup with sparing gaps that match to impact areas. Methods: The range ...

Dear Sir, Carcinoma of unknown primary (CUP) represents a heterogeneous group of metastatic tumors where, even after a complete diagnostic workup the site of origin of the tumor is not detected. The diagnosis of CUP should be made after complete clinical history, physical examination, routine laboratory tests, imaging, and a careful review of the histology, and sometimes radio-metabolic techniq...

Background: Oral feeding problems are among the most common issues in preterm infants. Various methods and feeding support tools are used in this regard, such as cup feeding and feeding nozzle. The present study aimed to determine the preferred method between cup feeding and feeding nozzle to support oral feeding in premature neonates. Methods: This clinical trial was conducted on 70 preterm i...
