Comment on "Effective of the q-deformed pseudoscalar magnetic field on the charge carriers in graphene"

We point out a misleading treatment in a recent paper published in this Journal [J. Math. Phys. (2016) 57, 082105] concerning solutions for the two-dimensional Dirac-Weyl equation with a q-deformed pseudoscalar magnetic barrier. The authors misunderstood the full meaning of the potential and made erroneous calculations, this fact jeopardizes the main results in this system.Comment: 7 pages, 2 figure

Card shuffling and diophantine approximation

The ``overlapping-cycles shuffle'' mixes a deck of $n$ cards by moving either the $n$th card or the $(n-k)$th card to the top of the deck, with probability half each. We determine the spectral gap for the location of a single card, which, as a function of $k$ and $n$, has surprising behavior. For example, suppose $k$ is the closest integer to $\alpha n$ for a fixed real $\alpha\in(0,1)$. Then for rational $\alpha$ the spectral gap is $\Theta(n^{-2})$, while for poorly approximable irrational numbers $\alpha$, such as the reciprocal of the golden ratio, the spectral gap is $\Theta(n^{-3/2})$.Comment: Published in at http://dx.doi.org/10.1214/07-AAP484 the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org

The English anthem

Thesis (M.A.)--Boston UniversityFrom the thirteenth century on, the antiphons to the propers of the Mass and to certain canticles of the Offices in the Roman Rite were sung to polyphonic motet settings. After the English Reformation in 1534, antiphons eventually disappeared from the services of the Book of Common Prayer and with them the motets. Because they had been a popular feature of the services, it was not long before a need was felt for an equivalent and the English anthem came into being. (The word "anthem" is but a corruption of the earlier terms for "antiphon".) The reformers desired that the complex additions of medieval pietism to the Roman Rite be either omitted or simplified and the attitude applied also to church music as did the ruling that all of the services be in a "tongue understanded of the people". The first Full Anthems of Tye, Tallis, Shepherd, Farrant, and others were in the simple, familiar style but with brief imitative "points" at the beginning of each phrase of the English text. The wish that the Archbishop of Canterbury, Thomas Cranmer, had expressed to Henry VIII that "the song...should not be full of notes but, as near as may be, for every syllable a note" was at first meticulously followed."

The Neural Connectivity of the Torus Semicircularis in the Cave Dwelling Form of Astyanax Fasciatus

Afferent projections of the torus semicircularis were traced in the blind cave form of Astyanax fasciatus using HRP tract-tracing techniques, and the results were compared to those found in previous studies of closely related sighted teleosts. Following unilateral injections of tracer to the nucleus centralis of the torus semicircularis, retrogradely labeled cells were found in two octaval nuclei of the medulla. The descending octavolateralis nucleus was labeled bilaterally and the anterior octaval nucleus was labeled primarily on the ipsilateral side. Both the descending and anterior octavolateralis nuclei are known to receive auditory input from CN VIII in sighted fish. In addition, labeled commissural fibers could be traced across the midline to labeled cells in the nucleus centralis of the contralateral torus semicircularis. Large Purkinje-like neurons of the contralateral medial octavolateralis nucleus of the medulla were labeled with HRP injections to the nucleus lateralis. The medial octavolateralis nucleus receives input from the anterior and posterior lateral line nerves known to carry mechanosensory information to the CNS. In addition, labeled cells in the contralateral descendens nucleus of V in the caudal medulla and in the ipsilateral ventromedial nucleus of the thalamus were found. Both of these nuclei process somatosensory information. Labeled cells were also located in the anterior tuberal nucleus of the hypothalamus and minor nuclei of the mesencephalon. These results suggest that the neural input to the torus semicircularis in cave A. fasciatus differ little, if any, from those previously found in sighted teleosts studied. Further, these findings also suggest that the torus semicircularis functions as a multimodal processing center with auditory input from the descending and anterior octavolateralis nuclei of the medulla, mechanosensory information relayed by the medial octavolateralis nucleus, and somatosensory input from the descendens nucleus of V and the ventromedial nucleus of the thalamus

AKUNTABILITAS INSTANSI PEMERINTAH DAERAH BERDASARKAN PERATURAN PRESIDEN REPUBLIK INDONESIA NOMOR 29 TAHUN 2014 TENTANG SISTEM AKUNTABILITAS KINERJA INSTANSI PEMERINTAH

Penelitian ini dilakukan dengan tujuan untuk mengetahui bagaimana pelaksanaan kinerja pemerintah daerah sesuai dengan asas akuntabilitas  dan bagaimana pengaturan mengenai akuntabilitas instansi pemerintah daerah berdasarkan Peraturan Presiden RI Nomor 29 Tahun 2014 tentang Sistem Akuntabilitas Kinerja Instansi Pemerintah. Dengan menggunakan metode penelitian yuridis normatif, disimpulkan: 1. Pelaksanaan kinerja pemerintah daerah sesuai dengan asas akuntabilitas berarti setiap kegiatan dan hasil akhir dari kegiatan penyelenggara pemerintahan pusat maupun daerah harus dapat dipertanggungjawabkan kepada masyarakat atau rakyat sebagai pemegang kedaulatan tertinggi negara sesuai dengan ketentuan peraturan perundang-undangan yang berlaku. 2. Pengaturan mengenai akuntabilitas instansi pemerintah daerah berdasarkan Peraturan Presiden RI Nomor 29 Tahun 2014 tentang Sistem Akuntabilitas Kinerja Instansi Pemerintah didasarkan pada penyelenggaraan SAKIP meliputi: rencana strategis; Perjanjian Kinerja; pengukuran Kinerja; pengelolaan data Kinerja; pelaporan Kinerja; dan reviu dan evaluasi Kinerja serta laporan pemerintah pusat.Kata kunci:  Akuntabilitas, Instansi, Pemerintah Daera

Scanning tunneling microscopy simulations of poly(3-dodecylthiophene) chains adsorbed on highly oriented pyrolytic graphite

We report on a novel scheme to perform efficient simulations of Scanning Tunneling Microscopy (STM) of molecules weakly bonded to surfaces. Calculations are based on a tight binding (TB) technique including self-consistency for the molecule to predict STM imaging and spectroscopy. To palliate the lack of self-consistency in the tunneling current calculation, we performed first principles density-functional calculations to extract the geometrical and electronic properties of the system. In this way, we can include, in the TB scheme, the effects of structural relaxation upon adsorption on the electronic structure of the molecule. This approach is applied to the study of regioregular poly(3-dodecylthiophene) (P3DDT) polymer chains adsorbed on highly oriented pyrolytic graphite (HOPG). Results of spectroscopic calculations are discussed and compared with recently obtained experimental datComment: 15 pages plus 5 figures in a tar fil
