Background: In mid-2022, a global mpox (formerly 'monkeypox') outbreak affecting predominantly gay and bisexual men emerged in non-endemic countries. Australia had never previously recorded mpox cases and there was no prior research on knowledge or attitudes to mpox among gay and bisexual men across Australia. Methods: We conducted a national, online cross-sectional survey between August 2022 and September 2022. Participants were recruited through community organisation promotions, online advertising, and direct email invitations. Eligible participants were gay, bisexual or queer; identified as male (cisgender or transgender) or non-binary; aged 16 years or older; and lived in Australia. the main outcome measures were: knowledge and concern about mpox; recognition of mpox symptoms and transmission routes; vaccination history; acceptability of behavioural changes to reduce mpox risk, and willingness to be vaccinated. Results: Of 2287 participants, most participants were male (2189/2287; 95.7%) and gay (1894/2287; 82.8%). Nearly all had heard about mpox (2255/2287; 98.6%), and the majority were concerned about acquiring it (1461/2287; 64.4%). Most of the 2268 participants not previously diagnosed with mpox correctly identified skin lesions (2087; 92%), rash (1977; 87.2%), and fever (1647; 72.6%) as potential symptoms, and prolonged and brief skin-to-skin contact as potential ways to acquire mpox (2124, 93.7%; and 1860, 82%, respectively). the most acceptable behavioural changes were reducing or avoiding attendance at sex parties (1494; 65.9%) and sex-on-premises venues (1503; 66.4%), and having fewer sexual partners (1466; 64.6%). Most unvaccinated and undiagnosed participants were willing to be vaccinated (1457/1733; 84.1%). Conclusions: People at risk of mpox should be supported to adopt acceptable risk reduction strategies during outbreaks and to seek vaccination. © 2023 CSIRO. All rights reserved.

Immersion in the Design: Design-for-assembly of Cable Harnesses

厦门大学学报（自然科学版） 2002年第S1期41卷 205-206页

Approaches to efficiency in manufacturing and assem bl y over the past 100 years have concentrated frequently on the twin themes of div iding jobs done by people into defined segments and to automating as many of tho se segments as possible. this approach to manufacturing engineering may be char acterised as one of deconstruction and replacement so far as the role of the hum an being is concerned. More recently design engineering has been approached in a similar light with research into ’intelligent’ methods involving, for example, expert systems or genetic algorithms to handle an increasing proportion of desi gn tasks. Expert systems are predicated on the idea that it is possible to capture and systemise significant amounts of professional knowledge: a task that has proved with experience to be much more difficult than when such systems wer e first proposed. Genetic algorithms, notwithstanding considerable research eff ort, have yet to make significant inroads into the practise of design and manufa cture. this paper will draw on new and previous experimental work carried out with supp ort from industry to propose an alternative approach that is enabled by the prod ucts of modern information technology. In this paradigm it is recognised that t he involvement of the human design expert is, for the time being at least, inevi table. Rather than seeking to reduce or even eliminate the " expert" with his or her tacit knowledge, the aim is to provide the expert with interactive to ols including immersive virtual reality so that implicit, human expertise can be applied effectively in the design cycle. the proposed approach is considered in the context of a particularly costly and difficult task, namely the design and planning for manufacture and assembly of c able harnesses for use in electro-mechanical artefacts. the efficient and reli able manufacture of cabling systems for many such products in the aerospace, aut omotive and It sectors provides diverse challenges to des

表面活性剂的浓度对Amott润湿指数及剩余油饱和度的影响

在油田注水开发其间，表面活性剂能够改变油、水两相之间的吸附性和界面张力。从而影响其Amott润湿指数和剩余油饱和度。文中研究了表面活性剂的浓度对它的影响。在温度为50℃时。在60块岩心柱中完成了水驱试验和Amott润湿指数试验，试验采用溶液是正庚烷和重量百分比为1.5％的Nacl溶液以及12种不同浓度的正十二烷基苯磺酸盐表面活性剂溶液，所使用岩心取自Berea沙岩，其平均孔隙度为19％，平均渗透率为104mD.实验结果表明。随着表面活性剂的浓度增加使岩石表面由水润湿性向弱的油润湿性转变。剩余油饱和度也随表面活性剂浓度的升高而降低；在表面活性剂浓度较低时其浓度较小的变化范围就可导致岩石表面从水润湿性通过过渡态最后到油润湿性的转变，该浓度范围与凝胶浓度临界点完全相符。在该浓度下对其吸附量进行测量。结果只相当于最大等温吸附值的10％，表面活性剂浓度越高。其吸附量也越高，而对真岩石表面的润湿性无太大影响。

Histological and Physiological Investigation of Channelrhodopsin-2 and Halorhodopsin in the Dorsal Cochlear Nucleus

Journal of Otology 2011年第1期6卷 10-19页

作者： t. Shimano B. Fyk-Kolodziej M. Asako K. tomoda S. Bledsoe Z.H. Pan S. Molitor A.G. holt Anatomy and Cell Biology Department Wayne State University School of Medicine Detroit MI 48201 USA Department of Otolaryngology Kansai Medical University Hirakata-city Osaka 573-1191 Japan Kresge Hearing Research Institute University of Michigan School of Medicine Ann Arbor MI 48109 USA Department of Bioengineering University of Toledo Toledo OH 43606 USA

We have delivered viral vectors containing either Chop2 fused with GFP, Channelrhodopsin-2 （ChR2）, or Halorhodopsin （HaloR） fused with mCherry （to form light gated cation channels or chloride pumps, respectively）, into the dorsal cochlear nucleus （DCN）. One to eighteen months later we examined the CN and inferior colliculus （IC） for evidence of virally transfected cells and processes. Production of ChR2 and HaloR was observed throughout the DCN. Rhodopsin localization within neurons was determined, with elongate, fusiform and giant cells identified based on morphology and location within the DCN. Production of ChR2 and HaloR was found at both the injection site as well as in regions projecting to and from the DCN. Light driven neuronal activity in the DCN was dependent upon the wavelength and intensity of the light, with only the appropriate wavelength resulting in activation and higher intensity light resulting in more neuronal activity. transfecting cells via viral delivery of rhodopsins can be useful as a tract tracer and as a neuronal marker to delineate pathways. In the future rhodopsin delivery and activation may be developed as an alternative to electrical stimulation of neurons.
