We present a formal analysis of symbolic learning that predicts significant differences in symbolic learning depending on the sequencing of semantic features and labels. A computational simulation confirms the FeatureLabel-Ordering (FLO) effect in learning that our analysis predicts. Discrimination learning is facilitated when semantic features predict labels, but not when labels predict semant...

A planar active retrodirective four-element array with subharmonic phase conjugation mixers based on anti-parallel diode pairs (APDPs) is proposed. As compared to previous phase conjugation mixers using twice RF frequency for LO frequency, the proposed conjugation mixers need only half RF frequency so that it can be easily applied for millimeter-wave applications. Receive, transmitting, local o...

Adenocarcinoma in Barrett’s esophagus has been increasing in incidence at a rapid rate for more than two decades. Cyclooxygenase (COX)-2 appears to play an important role in gastrointestinal carcinogenesis, and COX-2 overexpression has been demonstrated both in esophageal adenocarcinomas and in the metaplastic epithelium of Barrett’s esophagus. The aim of our study was to determine whether sele...

Snakehead, Channa striata, has a long history of invasion and associated negative impacts on the biodiversity native aquatic organisms in Mekong Delta. However, internal white spot disease caused by Aeromonas schubertii massive effect production snakehead fish but also can spread to wild populations consumers. The aim study was investigate prevalence multi-antibiotic resistance (MAR) A. isolate...

Abstract. Compound floods are an active area of research in which the complex interaction between pluvial, fluvial, coastal and groundwater flooding analyzed. A number studies have simulated compound impacts precipitation, river discharge storm surge variables with different numerical models linking techniques. However, is often neglected flood risk assessments due to its sporadic frequency (as...

Tương tự như chất kết dính thạch cao được chế tạo từ đá nhiên, phospho (PGB) (Phosphogypsum-PG) có nhược điểm lớn là không bền nước và cường độ thấp. Thành phần của PG chủ yếu chứa canxi sunphat dihydrat (CaSO4.2H2O) với hàm lượng thể hơn 75%, đồng thời tạp nhất định (từ 2÷6%). Các thường hợp Flo, P2O5, axit dư. Bài báo này trình bày một số quả nghiên cứu sử dụng tại Đình Vũ xi măng poóc lăng, ...
