Background: Severe obesity has increased more than three-fold in prevalence over the past fifteen years in Europe and the United States. Correctly identifying severe obesity permits access to mortality-reducing interventions. We aimed to determine the accuracy of healthcare professionals (HCPs) in recognising severe obesity and the frequency of body mass index (BMI) assessment by HCPs. Methods: We performed two cross-sectional surveys: one of 206 HCPs in Ireland and Canada and another of 515 Irish hospital healthcare records. The first survey evaluated BMI estimation from photographs and the second examined recording of weight and height during outpatient clinic visits. Results: HCPs underestimated the BMI of severely obese people by an average of 22% to 39%. For a patient with a BMI of 52 kg/m2, 35.4% of family physicians appreciated that the patient was severely obese (BMI > 40 kg/m2) compared with 81.0% of endocrinologists. During clinic visits only 18.1% (n = 75), 1% (n = 4) and 0% (n = 0) of patients had their respective weights, heights and BMIs recorded. Conclusions: HCPs frequently fail to recognise severe obesity from photographs and, in our centre, do not routinely record weight or height. Whether patient outcomes can be improved by measuring weight and height during every HCP encounter warrants further study.

Start-Ups Seek to Accelerate Path to Nuclear Fusion Mitch leslie

Engineering 2022年第5期8卷 6-8页

作者： Mitch leslie Senior Technology Writer

In September 2021,the world’s most powerful high-temperature superconducting magnet passed its first test,generating a 20 T magnetic field during a 5 h trial[1].The 3 m tall,9000 kg device(Fig.1)is the centerpiece of an ambitious plan by the start-up Commonwealth Fusion Systems,headquartered in Cambridge,MA,USA,to build a fusion reactor that produces more energy than it requires to stimulate and sustain its nuclear reactions[2,3].None of the experimental fusion approaches that scientists have tested has come close to that *** the multi-billion USD International Thermonuclear Experimental Reactor(ITER),the massive project sponsored by 35 countries that is under construction in southern France(Fig.2),is not projected to pass the breakeven point until the mid-2030s at the earliest[2,4].But Commonwealth Fusion Systems aims to have a pilot plant operating by 2025.

Charting Disaster Recovery via Google Street View: A Social Science Perspective on Challenges Raised by the Fukushima Nuclear Disaster

引用

International Journal of Disaster Risk Science 2016年第2期7卷 175-185页

作者： leslie Mabon School of Applied Social Studies Robert Gordon University

There is increasing interest in using Google Street View(GSV) for research purposes, particularly with regard to ‘‘virtually auditing'' the built environment to assess environmental quality. Research in this field to date generally suggests GSV is a reliable means of understanding the ‘‘real world'' environment. But limitations around the dates and resolution of images have been identified. An emerging strand within this literature is also concerned with the potential of GSV to understand recovery post-disaster. Using the GSV data set for the evacuated area around the Fukushima Dai'ichi nuclear power plant as a case study, this article evaluates GSV as a means of assessing disaster recovery in a dynamic situation with remaining uncertainty and a significant value and emotive dimension. The article suggests that GSV does have value in giving a high-level overview of the postdisaster situation and has potential to track recovery and resettlement over time. Drawing on social science literature relating to Fukushima, and disasters more widely, the article also argues it is imperative for researchers using GSV to reflect carefully on the wider socio-cultural contexts that are often not represented in the photo montage.

Farmers Reap Right to Repair Agricultural Equipment

引用

Engineering 2023年第8期27卷 8-10页

作者： Mitch leslie Senior Technology Writer

A farmer is ready to harvest the winter wheat crop when his combine harvester breaks *** if the problem would be relatively simple to remedy,the farmer probably cannot make the repair himself or get help from an independent shop because manufacturers have restricted access to the tools,documentation,and other requirements for fixing their equipment[1].Instead,the farmer will likely have to turn to one of the manufacturer’s dealers,which could mean waiting days or even weeks for a service call from a company technician[2].In the meantime,the farmer’s crop sits unharvested,vulnerable to damage or destruction by bad weather[2].

Commercial Moon Landings Multiply

作者： Mitch leslie Senior Technology Writer

Along with its familiar impact craters,the surface of the Moon sports numerous pale whorls and streaks known as lunar swirls[1].Likened to the pattern produced when someone pours cream into a cup of black coffee[2],the swirls can extend for more than 50 km and have puzzled researchers for centuries[3].Adding to their mystery,the features are associated with regions of magnetized rocks,an unusual attribute because the Moon lacks a magnetic field[3].Researchers do not know how the swirls are related to the magnetic fields or how they formed.

On 13 December 2022,a couple was driving through the Angeles National Forest near Los Angeles,CA,USA,when their car slid off the road,plowed 100 m down a steep hillside,and landed upside down at the bottom of a canyon[1].Although the couple suffered only minor injuries,they were trapped in the canyon,and in the remote area the passenger could not get any reception on her iPhone 14 cellular ***,she was able to send an SOS through a new feature on the phone that routes such messages via satellites[2].Rescuers alerted to the couple’s location airlifted them out of the canyon later the same day.

Adaptability of the ocean and earth tidal models based on global observations of the superconducting gravimeters

引用

Science China Earth Sciences 2005年第11期48卷 1859-1869页

作者： Ducarme Bernard Vandercoilden leslie Royal Observatory of Belgium 3av. Circulaire B-1180 Brussels Belgium

The adaptability of recent ocean tidal models and Earth tidal models is investigated comprehensively by means of 22 high precision tidal gravity observation series at 20 stations of the Global Geodynamics Project. Careful preprocessing of the original observations was carried out using international standard algorithms and the tidal gravity parameters were computed. The gravity load vectors of 8 main constituents are obtained based on loading computation theory and various global ocean models. The loading corrections of 14 secondary constituents are obtained based on a two-dimensional interpolation technique. Considering different characteristics of the wave amplitude, a method of “non-identical weighted mean” is developed for computing the av-eraged observed residual and remaining residual vectors at each station. The efficiency of the loading correction and the discrepancy between corrected amplitude factors and theoretical ones are analyzed. Meanwhile the calibration problem of the instruments is also discussed. After loading correction, the averaged tidal gravity parameters for all stations are obtained. The results show that the discrepancies between the global mean amplitude factors and theoretical values are less than 0.3%, the largest calibration error of the instruments is less than 0.5%. On the other hand, there are indications that the slight phase advance of K1 with respect to O1 in Mathews’ theory could be verified by ground based tidal gravity observations.

L^p Boundedness of Marcinkiewicz Integrals with H^1 Kernels

Acta Mathematica Sinica,English Series 2008年第6期24卷 1031-1038页

作者： leslie C.CHENG Department of Mathematics Bryn Mawr CollegeBryn MawrPA 19010USA

We establish the L^p boundedness of Marcinkiewicz integral operators with kernels in theHardy space on a compact submanifold of finite type. Previously such boundedness properties were obtained when the submanifold is a sphere. Our result shows that what matters is not the symmetry, but a certain type of curvature property of the submanifold.
