- To increase our understanding of the genetic basis of adiposity and its links to cardiometabolic disease risk, we conducted a genome-wide association meta-analysis of body fat percentage (BF%) in up to 100,716 individuals. Twelve loci reached genome-wide significance (P<5 × 10(-8)), of which eight were previously associated with increased overall adiposity (BMI, BF%) and four (in or near COBLL1/GRB14, IGF2BP1, PLA2G6, CRTC1) were novel associations with BF%. Seven loci showed a larger effect on BF% than on BMI, suggestive of a primary association with adiposity, while five loci showed larger effects on BMI than on BF%, suggesting association with both fat and lean mass. In particular, the loci more strongly associated with BF% showed distinct cross-phenotype association signatures with a range of cardiometabolic traits revealing new insights in the link between adiposity and disease risk.

- Annual air samples were collected at various sites in the Fildes Peninsula, West Antarctica from December 2010 to January 2018 using XAD-2 resin passive air samplers to investigate concentrations, temporal trends and potential sources of persistent organic pollutants (POPs) in Antarctic air. Relatively low concentrations of polychlorinated biphenyls (PCBs) (Σ19PCBs: 1.5-29.7 pg/m3), polybrominated diphenyl ethers (PBDEs) (Σ12PBDEs: 0.2-2.9 pg/m3) and organochlorine pesticides (OCPs) (Σ13OCPs: 101-278 pg/m3) were found in the atmosphere of West Antarctica. PCB-11, BDE-47 and hexachlorobenzene (HCB) were the predominant compounds in the atmosphere. The concentrations of PCBs, HCHs, DDTs and endosulfans were found to show decreasing temporal trends, whereas uniform temporal trends were observed for HCB. The atmospheric half-life values for PCBs, HCHs, DDTs and endosulfans in Antarctic air were estimated for the first time, using regressions of the natural logarithm of the concentrations versus the number of years, obtaining the values of 2.0, 2.0, 2.4 and 1.2 year, respectively. An increasing ratio of α-HCH/γ-HCH indicated long residence time for α-HCH and possible transformation of γ-HCH to α-HCH in the atmosphere. The ratios of p,p'-DDT/p,p'-DDE were mostly lower than unity in this study, which could be attributed to aged sources. It was found that long-range atmospheric transport was still considered to be the main contributing factor to the atmospheric levels of the POPs in West Antarctica whereas the contribution of human activities at the Chinese Great Wall Station was minor. The results of this study give a view on the most recent temporal trends and provide new insights regarding the occurrence of various POPs in the Antarctic atmosphere.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Vehicle control systems typically include chassis components that influence vehicle dynamics in three directions: longitudinal, lateral, and vertical. These three degrees of freedoms are controlled by chassis actuators such as brakes, steering, and suspensions, respectively. Traditionally, they were all mechanically controlled. For example, steering was actuated by the driver turning a steering wheel, which then caused the hydraulics in a power steering unit to amplify the driver-imposed torque and to create a desired wheel/tire rotation at the point of contact with the road.

Potential effectiveness of a stability control system for passenger cars after an initial side impact

Konferensbidrag (refereegranskat)abstract
- Vehicle multiple-event accidents constitute 1/4-1/3 of all severe accidents. The present paper studies the control of the vehicle’s abnormal motion after being hit by another vehicle. The potential effectiveness of such a stability control system is estimated through accident data analysis and vehicle dynamics simulation. Only side impacts were simulated, but engineering judgments were made to project the effectiveness potential prediction on the total traffic work. Assuming ESC-like control (closed loop control on yaw rate, using wheel brakes) it is found that the function has potential to mitigate accident for up to 10-9 cars per driven km, or up to 0.1% of the cars in the accident database. While assuming Post Impact Stability Control by steering (closed loop control on yaw angle and path deviation, using steering), the corresponding figures are approximately ten times higher.

Enhanced yaw stability control to mitigate a vehicle's abnormal yaw motion due to a disturbance
- 2013
-
Patent (övrigt vetenskapligt/konstnärligt)abstract
- An enhanced stability control system (200) for a vehicle includes a vehicle status sensor that generates a sensor signal. A driver input sensor that generates an input signal. A controller (214) may disable normal yaw stability control operation and enable body-force-disturbance (BFD) yaw stability control (YSC) operation, which includes at least partially reducing response functions of the normal yaw stability control associated with the input signal, in response to the sensor signal and performing BFD-YSC functions to achieve desired control performance upon the detection of BFD reception. The controller (214) may also or alternatively compare the sensor signal to a threshold and detect an improperly functioning/inoperative vehicle status sensor. The controller (214) disregards information associated with the improperly functioning/inoperative vehicle status sensor, and continues to perform enhanced yaw stability control operations.

STABILITY CONTROL SYSTEM WITH BODY-FORCE-DISTURBANCE HEADING CORRECTION
- 2009
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- A yaw stability control system for a vehicle detects and eliminates the vehicle yaw angle resulting from a body-force-disturbance and returns the vehicle to a pre disturbance heading. A yaw rate module generates a signal indicative of the vehicle yaw rate error. A yaw angle error module is triggered in response to a body-force-disturbance being detected by a body-force-disturbance detection unit, and performs integrations of the yaw rate signals to calculate a yaw angle error in order to obtain a correction of the vehicle yaw angle resulting from the body-force-disturbance. A yaw control module uses the yaw angle error in combination with the yaw rate error for a limited time period to generate yaw control signals that are sent to the vehicle brakes and/or active steering system for performing vehicle yaw stability control operations a signal to perform a body-force-disturbance yaw stability control operation for.Read more: http://www.faqs.org/patents/app/20090271073#ixzz2qAju8nV6
