die Performing Quiet: Aural Politics in Embodied Arts, Dec. 5 By events.berkeley.edu Published On :: Max Abner and Dahlia Nayar, Ph.D. candidates in performance studies, will present their in-progress dissertation research.Max Abner is a PhD candidate, musician, and curator who hails from Louisville, KY, has deep roots in Chicago, and is currently based in Oakland. Working from an anti-colonial settler positionality, he draws together discourses from sound studies, Indigenous studies, and critical theory to approach what he calls settler sound, a concept that accounts for the ways in which contested relations to colonized land play out in aural aesthetics. His dissertation attends to settler sound in the Bay Area experimental music/sound art scene. He has essays set for publication in Revealing Posthuman Encounters in Performance (Routledge) and Power in Listening: The Sound Out! Reader (NYU Press), his recorded curations can be heard on his music label Pontac Publications, and his live performance curations can be experienced at Beauty Supply Arts in Oakland. Dahlia Nayar’s project studies embodied manifestations of Quiet in multiple mediums of minoritarian performance. Her study curates a constellation of contemporary artists working in dance, theater, sound, and visual art with an attention to how Quiet emerges through bodies in relation to layered contexts and multiple subjectivities. She proposes that, as a minoritarian aesthetic, Quiet activates an ephemeral commons through resonance and attunement that allows expansive possibilities of relationality. Prior to her doctoral studies, Dahlia toured nationally and internationally as a choreographer, performer, and multimedia artist. She is a recipient of the Jacob Javits Fellowship, Massachusetts Cultural Council Fellowship in Choreography, and the National Dance Project Touring Award. Full Article
die Music Studies Colloquium: Walter Frisch, Nov. 21 By events.berkeley.edu Published On :: ‘Un Matisse Qui Chante’: Image, Sound, and Story in The Umbrellas of CherbourgWalter Frisch (Columbia University)The year 2024 marks the sixtieth anniversary of the release of Les Parapluies de Cherbourg(The Umbrellas of Cherbourg, 1964), which has since become a beloved classic in France and around the world. Diverging in many respects from the aesthetics of the contemporary Nouvelle Vague, Umbrellaswas a bold experiment by writer-director Jacques Demy and composer Michel Legrand that also departed markedly from traditional film musicals. Umbrellaswas sung from beginning to end, without any spoken dialogue. The creators aimed for a “transposed realism” that also bore little resemblance to opera. Legrand’s score, composed in close collaboration with Demy, was recorded before any filming began. The painterly costumes and sets were also coordinated with the music and screenplay. Umbrellashas been recognized as reflecting important cultural, political, and social issues of the France of its day, including modernization and commodification in the decades after World War II, the pervasive impact of Algerian War of 1954–1962, and changing family values during an early wave of feminism in France. More recently, Umbrellashas been interpreted within the framework of queer cinema. This talk will explore the genesis and unique qualities of Umbrellas, as well as some of these important contexts.Note: Frisch recommends watching Les Parapluies de Cherbourgin advance, if possible. It is available with subtitles on several streaming platforms. A reception will follow. Full Article

Ancient healers of the East believed that color had the unique capability of healing people's bodies and souls. The medicines of Ancient India, China, Egypt, Laos and other eastern countries had a trend called ra-therapy which cured people with the help of the rainbow colors. The ancient wise were not Orthodox and believed that energetic peculiarities of each person are unique. This in its turn means that each person has colors and shades that are particularly favorable for him.

die The impact of exchanging the light and heavy chains on the structures of bovine ultralong antibodies By journals.iucr.org Published On :: 2024-07-01 The third complementary-determining regions of the heavy-chain (CDR3H) variable regions (VH) of some cattle antibodies are highly extended, consisting of 48 or more residues. These `ultralong' CDR3Hs form β-ribbon stalks that protrude from the surface of the antibody with a disulfide cross-linked knob region at their apex that dominates antigen interactions over the other CDR loops. The structure of the Fab fragment of a naturally paired bovine ultralong antibody (D08), identified by single B-cell sequencing, has been determined to 1.6 Å resolution. By swapping the D08 native light chain with that of an unrelated antigen-unknown ultralong antibody, it is shown that interactions between the CDR3s of the variable domains potentially affect the fine positioning of the ultralong CDR3H; however, comparison with other crystallographic structures shows that crystalline packing is also a major contributor. It is concluded that, on balance, the exact positioning of ultralong CDR3H loops is most likely to be due to the constraints of crystal packing. Full Article text

Intramolecular N—H...O and C—H...O interactions consolidate the molecular structure. In the crystal, N—H...N interaction form S(5) zigzag chains along [010]. The most significant contributions to the Hirshfeld surface arise from H...H (33.2%), Br...H/H...Br (20.9%), O...H/H...O (11.2%), C...H/H...C (11.1%) and N...H/H...N (10%) contacts. The topology of the three-dimensional energy frameworks was generated using the B3LYP/6–31 G(d,p) model to calculate the total interaction energy. The net interaction energies for the title compound are Eele = 59.2 kJ mol−1, Epol = 15.5 kJ mol−1, Edis = 140.3 kJ mol−1 and Erep = 107.2 kJ mol−1 with a total interaction energy Etot of 128.8 kJ mol−1. The molecular structure was optimized by density functional theory (DFT) at the B3LYP/6–311+G(d,p) level and the theoretical and experimentally obtained parameters were compared. The frontier molecular orbitals HOMO and LUMO were generated, giving an energy gap ΔE of 4.0931 eV.

die Ultrashort large-bandwidth X-ray free-electron laser generation with a dielectric-lined waveguide By journals.iucr.org Published On :: 2024-02-09 Large-bandwidth pulses produced by cutting-edge X-ray free-electron lasers (FELs) are of great importance in research fields like material science and biology. In this paper, a new method to generate high-power ultrashort FEL pulses with tunable spectral bandwidth with spectral coherence using a dielectric-lined waveguide without interfering operation of linacs is proposed. By exploiting the passive and dephasingless wakefield at terahertz frequency excited by the beam, stable energy modulation can be achieved in the electron beam and large-bandwidth high-intensity soft X-ray radiation can be generated. Three-dimensional start-to-end simulations have been carried out and the results show that coherent radiation pulses with duration of a few femtoseconds and bandwidths ranging from 1.01% to 2.16% can be achieved by changing the undulator taper profile.

die Grazing-incidence synchrotron radiation diffraction studies on irradiated Ce-doped and pristine Y-stabilized ZrO2 at the Rossendorf beamline By journals.iucr.org Published On :: 2024-02-16 In this work, Ce-doped yttria-stabilized zirconia (YSZ) and pure YSZ phases were subjected to irradiation with 14 MeV Au ions. Irradiation studies were performed to simulate long-term structural and microstructural damage due to self-irradiation in YSZ phases hosting alpha-active radioactive species. It was found that both the Ce-doped YSZ and the YSZ phases had a reasonable tolerance to irradiation at high ion fluences and the bulk crystallinity was well preserved. Nevertheless, local microstrain increased in all compounds under study after irradiation, with the Ce-doped phases being less affected than pure YSZ. Doping with cerium ions increased the microstructural stability of YSZ phases through a possible reduction in the mobility of oxygen atoms, which limits the formation of structural defects. Doping of YSZ with tetravalent actinide elements is expected to have a similar effect. Thus, YSZ phases are promising for the safe long-term storage of radioactive elements. Using synchrotron radiation diffraction, measurements of the thin irradiated layers of the Ce-YSZ and YSZ samples were performed in grazing incidence (GI) mode. A corresponding module for measurements in GI mode was developed at the Rossendorf Beamline and relevant technical details for sample alignment and data collection are also presented.
