A number of wind tunnel tests have been conducted by the Wolfson Unit in aid of the development of sailing rigs for both cruising and racing boats, including recent tests for the United States Sailing Association as part of the joint IMS/PHRF research programme. In the process of these tests developments have been made in both the test techniques and the analysis methods, which have enabled the components of drag to be identified for different sail settings. This paper describes the tests for evaluating the upwind rig performance of a sloop and compares the components of drag with those in the aerodynamic model used in the IMS VPP. The aerodynamic behaviour of the rig is described using plots of the variation of sail forces and moments with sail settings with the aim of helping sailors understand the effects of changing sail settings. It is shown that the wind tunnel data match closely the IMS aerodynamic model and that this model can be simply programmed by sailors and designers into a spreadsheet to enable the rig planform to be optimised for particular conditions. The results are compared with those obtained using a full VPP calculation.

The Covid-19 pneumonia epidemic has broken out and spread in more than 215 countries, with more than 7 million confirmed cases worldwide, which will definitely have a huge negative impact on the global economy, and it has also given birth to populism and trade protectionism in some countries such as the United States. In particular, the trade friction between China and the United States has not been completely resolved, and the direction of the trade relationship has become an important issue in the post-epidemic era. Using retrospective research methods, dynamic analysis methods, and path analysis methods, we discovered the uncertainties in Sino-US trade relations under the epidemic. In the post-epidemic era, Sino-US trade relations will show long-term trade disputes, accompanied by complex politicization and normalization of talks while fighting. However, Sino-US trade is highly interdependent and cannot be divided. Therefore, China upholds to jointly build a community with a shared future for mankind, comprehensively deepens reform and opening up, adheres to dialogue and consultation, stabilizes the ballast of economic and trade relations, crosses the "Thucydides trap", and implements the strategy of expanding domestic demand to take the lead in restoring the economy during the epidemic. Responding to the trade war provoked by the United States against China also provides reference for in-depth research on trade-related theories.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
