Using data samples collected with the BESIII detector operating at BEPCII storage ring, we measure cross sections of $e^{+}e^{-}\rightarrow\pi^{+}\pi^{-}D^{+}D^{-}$ process center-of-mass energies from 4.190 to 4.946 GeV a partial reconstruction method. Two resonance structures are seen and parameters determined fit section line shape. The first observe has mass (4373.1 $\pm$ 4.0 2.2) MeV/$c^2$...

Introduction: Nowadays radiosensitive polymer gels are used as a reliable dosimetry tool for verification of 3D dose distributions. Special characteristics of these dosimeters have made them useful for verification of complex dose distributions in clinical situations. The aim of this work was to evaluate the capability of a normoxic polymer gel to determine electron dose distributions in differ...

We report the first low temperature scanning tunnelling microscopy and spec-troscopy study of high quality Bi 2 Sr 2 Ca 2 Cu 3 O 10+δ crystals. We present atomic resolution and show spectroscopic data acquired on two different samples. In one case, for T c = 109 K and a transition width of only 1 K, we obtained an extremely homogeneous sample with ∆ p = 60 meV over at least 50 nm. In the other ...

We report the influence of uniaxial tensile mechanical strain in the range 0-2.2% on the phonon spectra and bandstructures of monolayer and bilayer molybdenum disulfide (MoS2) two-dimensional crystals. First, we employ Raman spectroscopy to observe phonon softening with increased strain, breaking the degeneracy in the E' Raman mode of MoS2, and extract a Grüneisen parameter of ~1.06. Second, us...

Pituitary sarcoma is a rare late complication of radiotherapy for pituitary tumors. Although early case reports involved multiple courses of relatively low-energy radi ation therapy, pituitary sarcoma has been seen with single courses of high-energy x-ray or heavy particle radiotherapy . This report describes a fibrosarcoma of the pituitary occurring 5 years after 4,500 rad (45 Gy) of X-irradia...
