Forward flight stability in a drone-fly

Previous studies on forward flight stability in insects are for low to medium flight-speeds. In the present work, we investigated the stability problem for the full range of flight speeds (0–8.6 m/s) of a drone-fly. Our results show the following: The longitudinal derivatives due to the lateral motion are approximately 3 orders of magnitude smaller than the other longitudinal...

Generation of the pitch moment during the controlled flight after takeoff of fruitflies

In the present paper, the controlled flight of fruitflies after voluntary takeoff is studied. Wing and body kinematics of the insects after takeoff are measured using high-speed video techniques, and the aerodynamic force and moment are calculated by the computational fluid dynamics method based on the measured data. How the control moments are generated is analyzed by...

A non-targeted metabolomics study on different glucose tolerance states

A non-targeted metabolomics method was employed to study metabolic characteristics in subjects with different glucose tolerance. Plasma samples of 120 participants with normal glucose tolerance (NGT), impaired glucose regulation (IGR), and type 2 diabetes (T2D) were collected. Gas chromatography/mass spectrometry (GC/MS) was used to profile and compare the plasma metabolome among...

Hypervariable Region Polymorphism of mtDNA of Recurrent Oral Ulceration in Chinese

Background MtDNA haplogroups could have important implication for understanding of the relationship between the mutations of the mitochondrial genome and diseases. Distribution of a variety of diseases among these haplogroups showed that some of the mitochondrial haplogroups are predisposed to disease. To examine the susceptibility of mtDNA haplogroups to ROU, we sequenced the...

Molecular Aspect of Good Eating Quality Formation in Japonica Rice

The composition of amylopectin is the determinant of rice eating quality under certain threshold of protein content and the ratio of amylose and amylopectin. In molecular biology level, the fine structure of amylopectin is determined by relative activities of starch branching enzyme (SBE), granule-bound starch synthase (GBSS), and soluble starch synthase (SSS) in rice grain under...
