We present a detailed study of photophysical properties of single color centers in natural diamond samples emitting in the near infrared under optical excitation. Photoluminescence of these single emitters has several striking features, including narrow-band (FWHM 2 nm) fully polarized emission around 780 nm, a short excited-state lifetime of about 2 ns, and perfect photostability at room tempe...

Good Morning. It is indeed my privilege to be addressing you today in this Conference in which officials from industry and banking sector are participating. Today, I want to reflect on some of the challenges and dilemmas that we face as regulators of the banking system. A few of these challenges and dilemmas are in the context of the rapidly evolving regulatory landscape in the aftermath of the...

OVERVIEW OF CANADA c anada is a sparsely populated northern landmass of approximately 10 million km. Created in 1867 after French and then British colonization, the Canadian federation currently consists of 10 provinces and two territories. Provincial populations in 1991 (table 3-1) make apparent the rather imbalance distribution of Canadians across the country (119). Compounding this imbalance...

Arrays of nanodots were directly patterned by interferometric lithography using a bright table-top 46.9 nm laser. Multiple exposures with a Lloyd's mirror interferometer allowed to print arrays of 60 nm FWHM features. This laser-based extreme ultraviolet interferometric technique makes possible to print different nanoscale patterns using a compact table-top set up.

We have measured the first state-resolved, absolute cross sections for positron excitation of electronic states of an atom or molecule using a high resolution (Delta E approximately 25 meV FWHM) beam of positrons from a Penning-Malmberg trap. We present cross sections for the excitation of the low-lying levels of Ar, H(2), and N(2) for incident positron energies between threshold and 30 eV. For...

چکیده آترازین مهمترین علف کش خانواده ترایازینها است که جزو علف کش های با نیمه عمر متوسط طبقه بندی می شود. به منظور بررسی تأثیر کود آلی و مقدار کاربرد آن بر تجزیه آترازین، آزمایشی به صورت اسپلیت پلات در قالب طرح کاملاً تصادفی در سه تکرار در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد اجرا شد. کود آلی دو سطح (0 و 50 تن در هکتار) به عنوان کرت اصلی و مقدار کاربرد آترازین در دو سطح (2 و 4 کیلو...

We present a primal–dual memory efficient algorithm for solving a relaxed version of the general transportation problem. Our approach approximates the original cost function with a differentiable one that is solved as a sequence of weighted quadratic transportation problems. The new formulation allows us to solve differentiable, non– convex transportation problems.

Abstract. We survey half-linear dynamic equations on time scales. These contain the well-known half-linear differential and half-linear difference equations as special cases, but also other kinds of half-linear equations. Special cases of half-linear equations are the well-studied linear equations of second order. We discuss existence and uniqueness of solutions of corresponding initial value p...

For n odd, a half-cycle for Zn is a cycle [a1, a2, . . . , am] of distinct elements from Zn such that (a) m = (n − 1)/2, (b) the elements ai (i = 1, 2, . . . ,m) are all distinct, and (c) the differences ai+1 − ai (i = 1, 2, . . . ,m, with am+1 = a1) are all distinct and no two of them are the negatives of one another, modulo n. Similarly, a chaplet for Zn is now newly defined to be a cycle [a1...
