Few-cycle, broadband, mid-infrared optical parametric oscillator pumped by a 20-fs Ti:sapphire laser
A few-cycle, broadband, singly-resonant optical parametric oscillator (OPO) for the mid-infrared based on MgO-doped periodically-poled LiNbO3 (MgO:PPLN), synchronously pumped by a 20-fs Ti:sapphire laser is reported. By using crystal interaction lengths as short as 250 µm, and careful dispersion management of input pump pulses and the OPO resonator, near-transform-limited, few-cycle idler pulse...
Motivated by Nash equilibrium problems on ’curved’ strategy sets, the concept of Nash-Stampacchia equilibrium points is introduced for a finite family of non-smooth functions defined on geodesic convex sets of certain Riemannian manifolds. Characterization, existence, and stability of NashStampacchia equilibria are studied when the strategy sets are compact/noncompact subsets of certain Hadamar...
چکیده این تحقیق در بخشی از سامان عرفی شوراب چنار بگالی استان لرستان که بلوط ایرانی (quercus brantii lindl.) گونه غالب جنگل های آن است صورت پذیرفت. در مطالعه ی حاضر به منظور بررسی تاثیر عوامل توپوگرافی (ارتفاع از سطح دریا، شیب و جهت زمین) بر فاکتورهای تاج پوشش، مساحت تقریبی 1500 هکتار انتخاب گردید. سپس تعداد 147 قطعه نمونه مستطیلی به ابعاد 20 ×10 متر با استفاده از شبکه آماربرداری منظم - تصادفی ...
One of the central problems in the cell is how to transport molecules around the cell to desired locations. Since low Reynolds number conditions apply and diffusional times are large, without the aid of molecular motors to transport the fluid quickly cells could not survive, yet diffusion is still essential for the ultimate delivery of the goods. This paradox of low Reynolds numberlarge Peclet ...
feel that the results we show, particularly in Figure 6, are on much more complex examples and that we have processed much larger number of buildings than reported in the previous literature ([5], [2], and [9]). We feel that our method has advantage over monocular systems such as ([5]) due to its ability to infer 3-D more directly and of having several views to validate the hypotheses. We feel ...
