Electronic spectroscopy of carbon chain radicals using cw cavity ring down in conjunction with mass detection
No full textThe electronic absorption spectrum of the 2A'' − X 2A'' origin band of the
nonlinear carbon chain radical C6H4
+ was rotationally resolved by cw-CRD
spectroscopy [41]. It was analysed using a least-squares method and the rotational
constants of the ground and excited states were determined accurately. The 581 nm
band observed under the same discharge conditions is assigned to the same electronic
transition of C6H4
+ but involving the excitation of the ν12 vibrational mode in the
upper state based on comparison with ab initio results. The presented data provide a
basis for future observations of the C6H4
+ radical in both millimeter and infrared
regions.
A linear time-of-flight mass spectrometer was constructed to provide on-line
monitoring of the plasma discharge with a mass resolution of 1 amu at a range up to
120 amu. The results from the acetylene/helium plasma discharge are in good
agreement with those obtained using the reflectron TOF mass spectrometer and a
similar ion source [42]. To improve the experimental set-up, the following
modifications can be made:
• Transferring the signal from the oscilloscope directly to a PC via a
GPIB card will increase the speed of data processing;
• Computer control of the voltage applied will make the spectrometer
easier to operate;
• Using a metal grid at ground potential in front of MCP detector will
increase the flight time of ions improving the mass resolution;
• Installing a focusing lens will increase the number of ions arriving at
the detector, and therefore increase the signal on the oscilloscope

OCCASIONAL ONOMASTICON OF A CYCLE OF NOVELS ABOUT TANYA GROTTER BY DMITRIY EMETS AS A LINGUOCULTURAL PHENOMENON
No full textThis article discusses the specificity of occasional onomasticon in the cycle of novels
by Dmitriy Emets (b. 1974) featuring Tanya Grotter, which is an outstanding example
of fantasy literature, playing an important role in the modern cultural space, and
targeted mainly at children and teenagers. It has been established that while creating
the onomastic space of the cycle the author draws parallels with J. Rowling’s novels
about Harry Potter and forms onyms – occasionalisms based on the precedent names
(folk, mythological, religious, literary, and historical), foreign language vocabulary,
phraseology, etc. The desire to comprehend the author’s intention and to understand the
characteristics presented in onyms not only motivates readers to expand their horizon,
but also engages them in cross-cultural communication

Non-commutative differentiation and estimates on operator integrals
No full textIn 2017 Martijn Caspers, Fedor Sukochev and Dmitriy Zanin published a paper which generalises the proof of Davies' 1988 paper, and thus resolves the Nazarov-Peller conjecture. The proofs of these papers have been presented in this thesis. They have been expanded with a proof that generalises the conjecture to arbitrary Schatten classes. The optimality of the estimates in the conjecture is also studied, following the example of the 2016 paper by Coine et al. In addition, the quantum mechanical context is provided to interpret the presented results.Applied Mathematic

Weak (1,1) estimates for multiple operator integrals and generalized absolute value functions
No full textConsider the generalized absolute value function defined by a(t) = | t| tn−1, t∈ ℝ, n∈ ℕ≥ 1. Further, consider the n-th order divided difference function a[n]: ℝn+1 → ℂ and let 1 < p1, …, pn < ∞ be such that ∑l=1npl−1=1. Let Spl denote the Schatten-von Neumann ideals and let S1,∞ denote the weak trace class ideal. We show that for any (n + 1)-tuple A of bounded self-adjoint operators the multiple operator integral Ta[n]A maps Sp1×⋯×Spn to S1,∞ boundedly with uniform bound in A. The same is true for the class of Cn+1-functions that outside the interval [−1, 1] equal a. In [CLPST16] it was proved that for a function {atf} in this class such boundedness of Tf[n]A from Sp1×⋯×Spn to S1 may fail, resolving a problem by V. Peller. This shows that the estimates in the current paper are optimal. The proof is based on a new reduction method for arbitrary multiple operator integrals of divided differences.Accepted author manuscriptAnalysi
