Abstract

Background
The increasing prevalence of metabolic syndrome (MS) especially in female population, has become a major problem in health care systems. In this regards, it is necessary to identify the risk factors. Vitamin D deficiency is now proposed as one of the possible risk factors for metabolic syndrome, we investigated the relationship between vitamin D status and MS in female.

Methods
We searched observational studies with keywords Vitamin D, metabolic syndrome, metabolic syndrome X, insulin-resistance syndrome, metabolic cardiovascular syndrome and Reaven Syndrome X and female in pubmed, scopus, science direct, cochrane, web of science, google scholar and SID databases, regardless of publication time. Two hundred ninety five studies were found, and finally only 12 articles were selected according to exclusion and inclusion criteria.

Results
In nine studies that reported the prevalence of MS, the prevalence of MS among women with vitamin D deficiency was higher than female with normal vitamin D (34.5 vs. 30.2%). The prevalence of abdominal obesity, high blood pressure, high TG and HDL deficiency is higher in women with vitamin D deficiency. Also, the mean waist circumference, blood pressure, fast blood sugar (FBS), TG and BMI were higher. The most incident factor was high blood pressure (61.4 vs. 56.5%) and the lowest prevalence is associated with high FBS (32.2 vs. 33.5% in the other group).

Conclusion
The prevalence of MS is significantly associated with vitamin D deficiency, and among related factors, HDL, TG and blood pressure are statistically associated with vitamin D status.
Effects of solution and aging treatment parameters on the microstructure evolution of Ti–10V–2Fe–3Al alloy

AbstractThe solution-aging treatment parameters, including solution temperature, cooling rate and aging temperature, have significant influences on the microstructures and comprehensive mechanical properties of titanium alloy. In this work, the detailed microevolution behaviors of Ti–10V–2Fe–3Al alloy under different solution and aging conditions have been investigated through a series of heat-treatment experiments. The results of solution-treatment experiments reveal that the content of αp-phase is reduced to zero as the solution temperature is raised to a certain α → β critical transformation point. Recrystallized β-grains can be observed at the solution temperature of 820°C. In addition, the cooling way (air cooling or water cooling) has little influence on the microevolution behaviors for this alloy during the solution-treatment process. As for the solution-aging-treatment experiments, the results reveal that αs-phases are precipitated from the supersaturated β-phase, and the fraction of αs-phase increases with increasing aging temperature. However, the precipitated α-grains intend to coalesce and coarsen as the aging temperature raises above 510°C. Therefore, the advocated solution-aging-treatment program is solution treatment at 820°C with air cooling followed by aging treatment at 510°C with air cooling.

Redistribution of ground subtracks for aircraft noise calculations
Authors: Schwab Olivier 
Published: September 2020

Abstract
For aircraft noise calculations, lateral flight dispersion is commonly represented by means of subtracks – a backbone track and side-tracks to each side of the backbone track – where each subtrack is assigned a movement percentage. Aircraft noise calculations impose quality demands on these subtracks, while the latter are often created based on limited information.
This paper presents a method to increase flexibility when designing subtracks. The method allows to redistribute subtracks geometrically, allowing for the design of simplified track representations, for instance through a lower number of subtracks and very basic indications of movement allocations. The method is based on the geometric matching of the initial subtracks and on the estimation of the lateral movement distributions for both input and final output subtracks. No restrictions on the number of sub-tracks or on the shape of the distributions are needed, neither for the input nor for the output. A number of examples of the redistribution and its effect on aircraft noise calculations are discussed.
Simultaneous measurement of ionizing radiation and heart rate using a smartphone camera

Published: September 2020

AbstractComplementary metal oxide semiconductor (CMOS) cameras have been used to detect ionizing radiation when shaded from light or under the condition of static scenes. We propose a novel idea for simultaneous measurement of ionizing radiation and heart rate (HR) by using a smartphone with its CMOS camera lens covered by a finger in one measurement. Verified experiments were conducted: videos were recorded using a Xiaomi8 smartphone when the camera lens was covered by a finger and a light-tight tape for controlled experiment, with a ∼33 mCi 99mTc liquid radioactive source at six different distances (from 20 to 70 cm, step size 10 cm) from the camera. The exact HRs were measured using an oximeter at the same time. Image processing algorithm is proposed to extract radiation events and HR in the same videos. Results show that: (1) frame numbers containing radiation-related bright spots in two experiments have a linear relationship, and they are inversely proportional to the square of the distance between the camera and radiation source; (2) the HR difference between the video processing and the oximeter result is less than 2 beats per minute. In conclusion, it verifies that the proposed method is available to detect ionizing radiation and measure HR simultaneously with smartphone camera lens covered by a finger. We have been working on the development of an Android phone application based on the algorithms.
On Phase-over-Phase Configurations and phase collapsing:wh-extraction in V +de +CP clauses in Spanish
Authors: Martínez Vera Gabriel 
Published: September 2020

AbstractThis paper discusseswh-extraction in Spanish clauses involving a V +de+ CP sequence (de‘of’ is a preposition). The previous literature has observed that objects, but not adjuncts, can be extracted from a singlede +CP embedded clause. I make the following novel observations: (i) subjects pattern with adjuncts (not with objects) in that they cannot be extracted from a singlede +CP embedded clause, (ii) there is a ‘distance’ effect in that subject extraction improves when one more level of embedding is added, and (iii) there is also a ‘distance’ effect with regard to adjunct extraction, which improves when one more level of embedding is added. (i)–(iii) are surprising since subjects otherwise do not pattern with adjuncts with regard to extraction out of islands due to the pro-drop nature of Spanish, and adjunct extraction out of islands is otherwise uniformly unacceptable. I propose a phasal account of the pattern in question where Phase Collapsing (i.e., a mechanism whereby two phasal heads, heredeand C, are collapsed into one, thus voiding the phasehood of the lower phase headed by the C) and successive cyclic movement play crucial roles. I further extend the account to other cases where a CP co-occurs with a preposition.
