Background: To determine the accuracy of a simple and cost effective haematological scoring system (HSS) in the early diagnosis of neonatal sepsis using blood culture as a gold standard. Methods: In this prospective cross sectional study newborns (n=170) with history of prolonged rupture of membranes, maternal intrapartum fever > 1010 F or clinical signs of sepsis namely; neonatal fever ≥ 1010 ...

In view of the unstable cutting problem in the process of high speed milling hardened steel. Conduct experiment of the stability of machine tool and high speed milling cutter. The machine tool spindle vibration spectrum and vibration acceleration signal under the condition of different centrifugal force were detected. Obtained the critical speed of security and stability cutting of milling cutt...

Humanities and Social Sciences (HSS) increasingly absorb knowledge from Hard Sciences, i.e., Science, Technology, Agriculture and Medicine (STAM), as testified by a growing number of citations. However, whether citing more Hard Sciences brings more citations to HSS remains to be investigated. Based on China's HSS articles indexed by the Web of Science during 1998-2014, this paper estimated two-...

17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...

High-strength steels (HSSs) with nominal yield stress not less than 460 MPa have been increasingly employed in bridge structures. Compared SM490 normal-strength steel (NSS), HSSs, including SBHS500 and SM570, higher strength but lower ductility, brittle fracture can easily occur the HSSs members notches. Therefore, 48 tension specimens U-notch or V-notch made of SBHS500, SM570 structural are ca...

Owing to the progressive use of cold-formed high strength steel (HSS) for transportation applications, a characterisation fatigue behaviour HSS has become focal point material scientists and design engineers. To mimic components, specimen was adopted from previous research that features multiple bent sections. The geometry obtained by consecutive bending operations at room temperature. When sub...

In this paper, we study an important class of structured matrices: ”Hierarchically Semi-Separable (HSS)” matrices, for which an efficient hierarchical state based representation called Hierarchically Semi-Separable (HSS) representation can be used to utilize the data sparsity of the HSS matrices. A novel algorithm with O(n) complexity is proposed to construct suboptimal HSS representations from...
