| 2 | The evolution of corneal and refractive surgery with the femtosecond laser显示文摘The use of femtosecond lasers has created an evolution in modern corneal and refractive surgery.With accuracy,safety,and repeatability,eye surgeons can utilize the femtosecond laser in almost all anterior refractive procedures;laser in situ keratomileusis(LASIK),small incision lenticule extraction(SMILE),penetrating keratoplasty(PKP),insertion of intracorneal ring segments,anterior and posterior lamellar keratoplasty(Deep anterior lamellar keratoplasty(DALK)and Descemet's stripping endothelial keratoplasty(DSEK)),insertion of corneal inlays and cataract surgery.As the technology matures,it will push surgical limits and open new avenues for ophthalmic intervention in areas not yet explored.As we witness the transition from femto-LASIK to femto-cataract surgery it becomes obvious that this innovation is here to stay.This article presents some of the most relevant advances of femtosecond lasers to modern corneal and refractive surgery. | Antonis Aristeidou Elise V.Taniguchi Michael Tsatsos Rodrigo Muller Colm McAlinden Roberto Pineda Eleftherios I.Paschalis | 2015 | Eye and Vision2015,2,1: | 9 |
| 3 | Decreasing nutrient concentrations in soils and trees with increasing elevation across a treelineecotone in Rolwaling Himal, Nepal显示文摘At a global scale, tree growth in alpine treeline ecotones is limited by low temperatures. At a local scale, however, tree growth at its upper limit depends on multiple interactions of influencing factors and mechanisms. The aim of our research was to understand local scale effects of soil properties and nutrient cycling on tree growth limitation, and their interactions with other abiotic and biotic factors in a near-natural Himalayan treeline ecotone. Soil samples of different soil horizons, litter, decomposition layers, and foliage samples of standing biomass were collected in four altitudinal zones along three slopes, and were analysed for exchangeable cations and nutrient concentrations, respectively. Additionally, soil and air temperature, soil moisture, precipitation, and tree physiognomy patterns were evaluated. Both soil nutrients and foliar macronutrient concentrations of nitrogen(N), magnesium(Mg), potassium(K), and foliar phosphorus(P) decrease significantly with elevation. Foliar manganese(Mn) concentrations, bycontrast, are extraordinarily high at high elevation sites. Potential constraining factors on tree growth were identified using multivariate statistical approaches. We propose that tree growth, treeline position and vegetation composition are affected by nutrient limitation, which in turn, is governed by low soil temperatures and influenced by soil moisture conditions. | Simon DROLLINGER Michael MULLER Timo KOBL Niels SCHWAB Jurgen BOHNER Udo SCHICKHOFF Thomas SCHOLTEN | 2017 | Journal of Mountain Science2017,14,5: | 4 |
| 4 | Implications of tree species–environment relationships for the responsiveness of Himalayan krummholz treelines to climate change显示文摘Climate warming is expected to advance treelines to higher elevations. However, empirical studies in diverse mountain ranges give evidence of both advancing alpine treelines as well as rather insignificant responses. In this context, we aim at investigating the sensitivity and responsiveness of the near-natural treeline ecotone in Rolwaling Himal, Nepal, to climate warming. We analysed population densities of tree species along the treeline ecotone from closed forest stands via the krummholz belt to alpine dwarf shrub heaths(3700-4200 m) at 50 plots in 2013 and 2014. We quantified species-environment relationships, i.e. the change ofenvironmental conditions(e.g., nutrient and thermal deficits, plant interactions) across the ecotone by means of redundancy analyses, variation partitioning and distance-based Moran's eigenvector maps. In particular, we focus on explaining the high competitiveness of Rhododendron campanulatum forming a dense krummholz belt and on the implications for the responsiveness of Himalayan krummholz treelines to climate change. Results indicate that treeline trees in the ecotone show species-specific responses to the influence of environmental parameters, and that juvenile and adult tree responses are modulated by environmental constraints in differing intensity. Moreover, the species-environment relationships suggest that the investigated krummholz belt will largely prevent theupward migration of other tree species and thus constrain the future response of Himalayan krummholz treelines to climate warming. | Niels SCHWAB Udo SCHICKHOFF Birgit BURZLE Michael MULLER Jurgen BOHNER Ram Prasad CHAUDHARY Thomas SCHOLTEN Jens OLDELAND | 2017 | Journal of Mountain Science2017,14,3: | 3 |

| 15 | An ultra-compact particle size analyser using a CMOS image sensor and machine learning显示文摘Light scattering is a fundamental property that can be exploited to create essential devices such as particle analysers.The most common particle size analyser relies on measuring the angle-dependent diffracted light from a sample illuminated by a laser beam.Compared to other non-light-based counterparts,such a laser diffraction scheme offers precision,but it does so at the expense of size,complexity and cost.In this paper,we introduce the concept of a new particle size analyser in a collimated beam configuration using a consumer electronic camera and machine learning.The key novelty is a small form factor angular spatial filter that allows for the collection of light scattered by the particles up to predefined discrete angles.The filter is combined with a light-emitting diode and a complementary metal-oxide-semiconductor image sensor array to acquire angularly resolved scattering images.From these images,a machine learning model predicts the volume median diameter of the particles.To validate the proposed device,glass beads with diameters ranging from 13 to 125μm were measured in suspension at several concentrations.We were able to correct for multiple scattering effects and predict the particle size with mean absolute percentage errors of 5.09% and 2.5% for the cases without and with concentration as an input parameter,respectively.When only spherical particles were analysed,the former error was significantly reduced(0.72%).Given that it is compact(on the order of ten cm)and built with low-cost consumer electronics,the newly designed particle size analyser has significant potential for use outside a standard laboratory,for example,in online and in-line industrial process monitoring. | Rubaiya Hussain Mehmet Alican Noyan Getinet Woyessa Rodrigo R.Retamal Marin Pedro Antonio Martinez Faiz M.Mahdi Vittoria Finazzi Thomas A.Hazlehurst Timothy N.Hunter Tomeu Coll Michael Stintz Frans Muller Georgios Chalkias Valerio Pruneri | 2020 | Light(Science & Applications)2020,9,1: | 1 |
