Based on the results of an on-going monitoring program of 1612 MHz OH masers in OH/IR stars, we determined a lifetime encompassing late AGB and early post-AGB evolution of at least 4500 years. Fading of the OH masers observed with the Nançay Radio Telescope is detected in several post-AGB OH/IR stars on timescales of decades, while AllWISE/NEOWISE light curves taken almost in parallel show diverse
Background: Tuberculosis (TB) disease has been associated with pregnancy complications. However, the potential impact of TB infection (TBI) on pregnancy outcome is unknown. To investigate this, we conducted a register-based study in immigrant women screened with QuantiFERON assays for TBI in antenatal care in Sweden. Methods: Women with history of immigration from TB-endemic countries were eligibl
One in six couples seeks help for infertility during their reproductive years. Subfertility investigations should be performed without delays (because female fertility decreases with age) and should be as noninvasive as possible. Many fertility clinics use diagnostic hysteroscopy to assess the uterine cavity and evaluate the tubal ostia. Laparoscopy is also often used to examine internal pelvic or
This paper analyses optimal subband beamforming performance mainly aimed at speech enhancement and acoustic echo suppression for personal communication devices, personal computers and wireless cellular telephones. The focus is on theoretical limits of finite impulse response (FIR) beamformers for spatially spread sources in the array near-field. Performance of the Wiener solution is compared to th
This paper focuses on the relation between large car manufacturers' incentive and opportunity to innovate and their electric vehicle (EV) business strategies. We analyze how environmental regulation and the firm's incentive (measured by net income) and opportunity to innovate (measured by EV asset position, determined from a combination of patent, partnership and prototype data) affected EV sales
This research will explore the field of social movements by explaining why and how a minority social movement persists despite persistent constraints placed upon it by a majority-dominated state. The Chinese education movement has been one of the largest and most sustained social movements in Malaysia. Sociological, economic, and demographic changes of the Chinese community along with domestic pol
The aim of this study was to investigate torso cooling benefit of various PCM vests in a simulated warm environment (Ta= 34 °C, RH=56 %, Va=0.4 m/s). A pre-wetted cotton torso fabric skin was used to simulate sweating on a thermal manikin (Tmanikin=34 °C). Six conditions were tested: nude fabric skin (Fabric Skin), Vest A without (VA) and with frozen gels with a melting temperature (Tm) of 0 °C (V
To accurately model the effect on the dynamic behavior of a floor when using glue in the joints between the chipboards and beams in a lightweight structure can be a daunting task. It is however important to have a model that can simulate these junctions with high fidelity. The behavior of T-junctions with different geometries and methods of adhesion has been previously investigated via measurement
Remote sensing is used by the Department of Environment, Climate change and Water (DECCW) for mapping and monitoring the extent of woody vegetation in the State of New South Wales (NSW). In the past DECCW has relied solely on Landsat imagery to provide for these requirements but the need to map woody vegetation change in landscapes such as open woodlands with scattered trees, grasslands, and highl
