Alexander Rehding. 2009. Music and Monumentality: Commemoration and Wonderment in Nineteenth-Century Germany. Oxford and New York: Oxford University Press.
Creators: Kim, Ji Young
Publisher: name: Columbia University
Year: 2011
Subjects: Music

description: Music and Monumentality remains a thought-provoking book that traverses familiar territory with a fresh perspective. Rehding's project is at once modest and ambitious: modest in that it makes no claims to comprehensiveness, ambitious in the scope and gravity of the questions raised. The result is that its treatment of the material is not always commensurate to the magnitude of the issues at stake. Nevertheless, the book stands as a laudable attempt to capture the contingency of historical phenomena. Both the concept of monumentality and the objects that sustain it are embedded in an intricate web of relationships that cannot be easily disentangled. Put another way, Music and Monumentality stands as an eloquent symptom of the early twenty-first -century condition: a disturbed, fragmented collective memory that may only apprehend the nineteenth century as a collection of souvenirs
Radial Velocities of Stars with Multiple Co-orbital Planets

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: To date, well over a thousand planets have been discovered orbiting other stars, hundreds of them in multi-planet systems. Most of these exoplanets have been detected by either the transit method or the radial velocity method, rather than by other methods such as astrometry or direct imaging. Both the radial velocity and astrometric methods rely upon the reflex motion of the parent star induced by the gravitational attraction of its planets. However, this reflex motion is subject to misinterpretation when a star has two or more planets with the same orbital period. Such co-orbital planets may effectively "hide" from detection by current algorithms. In principle, any number of planets can share the same orbit; the case where they all have the same mass has been studied most. Salo and Yoder (A & A 205, 309--327, 1988) have shown that more than 8 planets of equal mass sharing a circular orbit must be equally spaced for dynamical stability, while fewer than 7 equal-mass planets are stable only in a configuration where all of the planets remain on the same side of their parent star. For 7 or 8 equal-mass planets, both configurations are stable. By symmetry, it is clear that the equally-spaced systems produce no reflex motion or radial velocity signal at all in their parent stars. This could lead to their being overlooked entirely, unless they happen to be detected by the transit method. It is equally clear that the lopsided systems produce a greater radial velocity signal than a single such planet would, but a smaller signal than if all of the planets were combined into one. This could seriously mislead estimates of exoplanet masses and densities. Transit data and ellipsoidal (tidal) brightness variations in such systems also are subject to misinterpretation. This behavior is also representative of more natural systems, with co-orbital planets of different masses.

Transgender, Queer Theory, and Psychoanalysis
Creators: name: Stryker, Susan
Publisher: name: punctum books
Year: 2017

description: The inclusion of trans*1 material in this collection of essays on the encounter between psychoanalysis and queer theory neces-sarily raises the question of the relationship of trans* to queer, as well as trans* to psychoanalysis. The  five  essays  that  deal  explicitly  with  trans*  issues—Gh-erovici,  Corbett,  Kaplan,  Weatherill,  and  Geldhof  and  Ver-haeghe—each  approach  these  matters  somewhat  differently.  Weatherill  makes  only  passing,  and  transphobic,  mention  of  transgender  women  when  he  approvingly  quotes  Germaine  Greer’s gratuitously vulgar dismissal of such individuals’ claims to  social  existence:  “just  because  you  lop  off  your  dick  doesn’t  make you a fucking woman.” For Geldhof and Verhaeghe, trans* positions are “extreme representatives” of a queer social move-ment that seems “to refuse the classical distinction between man and woman.” For Kaplan, “trans” represents a benign albeit limiting investment in fixed gender identities that is counterposed to the supposed fluidity, and desirability, of queer gender expres-sion. Though he does not use the trans* nomenclature, Corbett’s nuanced  discussion  of  “queer  childhood”  is  attuned  to  those  moments  “in  which  the  social  order  of  gender  is  challenged,”  and  in  which  a  “transforming  nexus”  of  gender  mallability  is  created  that  allows  for  gender’s  resignification  through  collec-tive  intersubjective  fantasies  between  queer  children  and  their  significant others. For Gherovici, transness and homosexuality both  address,  in  nonheteronormative  ways,  the  imperative  to  assume a psychical position in relation to the question of sexual difference; they are divergent yet equally viable sinthomes, or an-swers to the unavoidable riddle of how the Real, Imaginary, and Symbolic registers might be knotted together.

description: This paper describes our ongoing work on security verification against inference attacks on data trees. We focus on infinite secrecy against inference attacks, which means that attackers cannot narrow down the candidates for the value of the sensitive information to finite by available information to the attackers. Our purpose is to propose a model under which infinite secrecy is decidable. To be specific, we first propose tree transducers which are expressive enough to represent practical queries. Then, in order to represent attackers' knowledge, we propose data tree types such that type inference and inverse type inference on those tree transducers are possible with respect to data tree types, and infiniteness of data tree types is decidable.

The Psychoanalysis that Dare Not Speak Its Name
Creators: name: Nierenberg, Ona
Publisher: name: punctum books
Year: 2017

description: In  the  opening  essay  of  Love  In  A  Dark  Time:  Gay  Lives  from  Wilde to Almodovar, Colm Tóibin refers to Borges’s essay “The Argentine Writer and Tradition” to describe the position of exile as a condition for creation, for the possibility of the emergence of the new. Tóibin situates gay literary figures alongside the Jew-ish, Argentine, and Irish artists that Borges refers to, underlin-ing that the place of estrangement, of foreignness, is the sine qua non for speaking at the limits of the sayable. While certainly not sufficient,  extra-territoriality  is  absolutely  necessary  to  affect  a  break  with  the  mortifications  referred  to  by  Freud  (1926a)  as  “the compact majority” (274).

description: Graphene exhibits extraordinary electronic and mechanical properties, and extremely high thermal conductivity. Being a very stable atomically thick membrane that can be suspended between two leads, graphene provides a perfect test platform for studying thermal conductivity in two-dimensional systems, which is of primary importance for phonon transport in low-dimensional materials. Here we report experimental measurements and non-equilibrium molecular dynamics simulations of thermal conduction in suspended single layer graphene as a function of both temperature and sample length. Interestingly and in contrast to bulk materials, when temperature at 300K, thermal conductivity keeps increasing and remains logarithmic divergence with sample length even for sample lengths much larger than the average phonon mean free path. This result is a consequence of the two-dimensional nature of phonons in graphene and provides fundamental understanding into thermal transport in two-dimensional materials.

description: We study a continuum model of an extensile active nematic to show that mesoscale turbulence develops in two stages: (i) ordered regions undergo an intrinsic hydrodynamic instability generating walls, lines of stong bend deformations, (ii) the walls relax by forming oppositely charged pairs of defects. Both creation and annihilation of defect pairs reinstate nematic regions which undergo further instabilities, leading to a dynamic steady state. We compare this with the development of active turbulence in a contractile active nematic.
The direct CP violation in a general two Higgs doublet model

description: In this paper, we study the CP violating processes in a general two-Higgs-doublet model (2HDM) with tree-level flavor changing neutral currents. In this model, sizable Yukawa couplings involving top and charm quarks are still allowed by the collider and flavor experiments, while the other couplings are strongly constrained experimentally. The sizable couplings, in general, have imaginary parts and could largely contribute to the CP violating observables concerned with the $B$ and $K$ mesons. In particular, the contribution may be so large that it affects the direct CP violating $K$ meson decay, where the discrepancy between the experimental result and the Standard Model prediction is reported. We discuss how well the anomaly is resolved in the 2HDM, based on study of the other flavor observables. We also propose the way to test our 2HDM at the LHC.

description: Let $M$ be a closed connected spin manifold such that its spinor Dirac operator has non-vanishing (Rosenberg) index. We prove that for any Riemannian metric on $V = M \times [-1,1]$ with scalar curvature bounded below by $σ> 0$, the distance between the boundary components of $V$ is at most $C_n/\sqrtσ$, where $C_n = \sqrt{(n-1)/{n}} \cdot C$ with $C < 8(1+\sqrt{2})$ being a universal constant. This verifies a conjecture of Gromov for such manifolds. In particular, our result applies to all high-dimensional closed simply connected manifolds $M$ which do not admit a metric of positive scalar curvature. We also establish a quadratic decay estimate for the scalar curvature of complete metrics on manifolds, such as $M \times \mathbb{R}^2$, which contain $M$ as a codimension two submanifold in a suitable way. Furthermore, we introduce the "$\mathcal{KO}$-width" of a closed manifold and deduce that infinite $\mathcal{KO}$-width is an obstruction to positive scalar curvature.

description: We expect to be able to recognize what we see in the visual field but visual experience occurs around a void, an emptiness, over which the artist places semblants. In The Ethics of Psychoanalysis (2008[1959–60]),  Lacan  likened  this  to  a  vase  that  puts  a  skin  around  a  hole  and  veils  the  open  sewer  beneath.  A  “nothing”  becomes a “something.” An object is made to exist (148–49).The  marked  and  voided  spaces  around  Karla  Black’s  sus-pended piece There Can Be No Arguments play with fullness and emptiness,  not  only  as  background  for  the  works  in  space  she  makes. The marks are written on the rim of the Real. They are not  about  metaphor  or  producing  meaning.  Strip  meaning  or  the hope of it away and an encounter emerges. She dresses and addresses a void.

description: The dependence of the Raman spectrum on the excitation energy has been investigated for ABA-and ABC- stacked few-layer graphene in order to establish the fingerprint of the stacking order and the number of layers, which affect the transport and optical properties of few-layer graphene. Five different excitation sources with energies of 1.96, 2.33, 2.41, 2.54 and 2.81 eV were used. The position and the line shape of the Raman 2D, G*, N, M, and other combination modes show dependence on the excitation energy as well as the stacking order and the thickness. One can unambiguously determine the stacking order and the thickness by comparing the 2D band spectra measured with 2 different excitation energies or by carefully comparing weaker combination Raman modes such as N, M, or LOLA modes. The criteria for unambiguous determination of the stacking order and the number of layers up to 5 layers are established.

A fast algorithm for computing the characteristic polynomial of the p-curvature

description: We discuss theoretical and algorithmic questions related to the $p$-curvature of differential operators in characteristic $p$. Given such an operator $L$, and denoting by $\Chi(L)$ the characteristic polynomial of its $p$-curvature, we first prove a new, alternative, description of $\Chi(L)$. This description turns out to be particularly well suited to the fast computation of $\Chi(L)$ when $p$ is large: based on it, we design a new algorithm for computing $\Chi(L)$, whose cost with respect to $p$ is $\softO(p^{0.5})$ operations in the ground field. This is remarkable since, prior to this work, the fastest algorithms for this task, and even for the subtask of deciding nilpotency of the $p$-curvature, had merely slightly subquadratic complexity $\softO(p^{1.79})$.

description: This paper presents a novel radio frequency (RF) beam training algorithm for sparse multiple input multiple output (MIMO) channels using unitary RF beamforming codebooks at transmitter (Tx) and receiver (Rx). The algorithm leverages statistical knowledge from past beam data for expedited beam search with statistically-minimal training overheads. Beams are tested in the order of their ranks based on their probabilities for providing a communication link. For low beam entropy scenarios, statistically-ranked beam search performs excellent in reducing the average number of beam tests per Tx-Rx beam pair identification for a communication link. For high beam entropy cases, a hybrid algorithm involving both memory-assisted statistically-ranked (MarS) beam search and multi-level (ML) beam search is also proposed. Savings in training overheads increase with decrease in beam entropy and increase in MIMO channel dimensions.

description: Let $V\in\mathbb{Q}(i)(\a_1,\dots,\a_n)(\q_1,\q_2)$ be a rationally parametrized planar homogeneous potential of homogeneity degree $k\neq -2, 0, 2$. We design an algorithm that computes polynomial \emph{necessary} conditions on the parameters $(\a_1,\dots,\a_n)$ such that the dynamical system associated to the potential $V$ is integrable. These conditions originate from those of the Morales-Ramis-Simó integrability criterion near all Darboux points. The implementation of the algorithm allows to treat applications that were out of reach before, for instance concerning the non-integrability of polynomial potentials up to degree $9$. Another striking application is the first complete proof of the non-integrability of the \emph{collinear three body problem}.

Afterword: Reflections on the Encounters between Psychoanalysis and Queer Theory
Creators: name: Watson, Eve
Publisher: name: punctum books
Year: 2017

description: Clinical  Encounters  in  Sexuality  brings  together  two  altogether  different  disciplines  that  address  the  field  of  human  sexual-ity: clinical psychoanalysis and queer theory. This encounter is underpinned  by  the  centrality  of  sexuality  to  both  disciplines  and  the  crucial  nature  of  psychoanalytic  theory  to  queer  the-ory’s theorization of gender and sexuality. Beginning with Sig-mund  Freud,  psychoanalysis  has  a  long  history  of  turning  to  other  fields  such  as  philosophy,  art,  literature,  linguistics,  sci-ence, mathematics, and religion to develop and differentiate its major  themes.  This  collection  adds  the  work  of  queer  theory  to  this  list  of  co-conspirators  addressing  the  question  of  what  it is to be uniquely human, especially important today in light of the homogenizing effects of globalization, marketization and digitalization. Queer theory proffers a breadth of critical think-ing  about  contemporary  sexuality,  mechanisms  of  bio-power  and  regimes  of  normativization  for  psychoanalysts  to  address  themselves  to.  Queer  theory’s  use  of  psychoanalysis  is  critical  to  its  Foucault-inspired  project  of  critically  exploring  desire,  pleasure, identity and the social fabric itself. Psychoanalysts, for their part, offer psychoanalytic theory, clinical practice and the extraordinary  value  of  the  clinical  vignette,  the  psychoanalytic  tool par excellence. In addition, theorists of psychoanalysis and sexuality  bring  their  insights  to  bear  on  this  “queer”  marriage  between psychoanalysis and queer theory for readers to add to their experience of the book.

description: In this paper, we obtain and study typical beam entropy values for millimetre wave (mm-wave) channel models using the NYUSIM simulator for frequencies up to 100 GHz for fifth generation (5G) and beyond 5G cellular communication systems. The beam entropy is used to quantify sparse MIMO channel randomness in beamspace. Lower relative beam entropy channels are suitable for memory-assisted statistically-ranked (MarS) and hybrid radio frequency (RF) beam training algorithms. High beam entropies can potentially be advantageous for low overhead secured radio communications by generating cryptographic keys based on channel randomness in beamspace, especially for sparse multiple input multiple output (MIMO) channels. Urban micro (UMi), urban macro (UMa) and rural macro (RMa) cellular scenarios have been investigated in this work for 28, 60, 73 and 100 GHz.

Glossing the Gloss of "Envois" in The Post Card
Creators: name: Miller, J. Hillis
Publisher: name: punctum books
Year: 2017

description: The  Post  Card  invites  glossing  of  all  sorts.  It  is  an  immensely  complex  and  rich  text,  one  of  Derrida’s  most  fascinating  and  challenging. La  carte  postale  is  full  of  specific  historical  and  personal references that will puzzle many readers. Many formu-lations  and  allusions  are  enigmatic  or  counter-intuitive.  They  need  explanatory  glossing.  Derrida  uses  just  about  every  rhe-torical  device  and  figure  of  speech  in  the  book.  You  name  it,  it  is  there  (il  y  a  là):  puns  (calembours),  metaphor,  metonymy,  synecdoche,  catachresis,  apostrophe,  prosopopoeia,  hyperbole,  prolepsis,  analepsis,  ellipsis,  paradox,  aporia,  and  of  course  a  constant  pervasive  destabilizing  irony.  How  can  you  tell  when  this joker is telling the truth or speaking straight, if ever? “Envois,”  moreover,  is  full  of  complex  wordplay  that  is  not  exactly “figurative” in the usual sense. This wordplay is often not easily  translatable  from  French  to  English.  One  tiny  example:  In  the  last  entry  for  February  1979,  Derrida  writes:  “La  séance  continue, tu analyse ça comment? Je parle grammaire, comme toujours,  c’est  un  verbe  ou  un  adjectif ?”  (“La  séance  continue,  how  do  you  analyze  that?  I’m  talking  grammar,  as  always,  is  it  a verb or an adjective?” [PC, 178/193]) Derrida here plays on an untranslatable ambiguity on whether “continue” in the French is verb or an adjective. In the first case, the locution would mean: “The session continues.” In the second, “The continued session.” It makes a lot of difference which way you read it, as a duck or as a rabbit, as in the famous Gestaltist diagram that oscillates un-predictably before the viewer’s eyes between those two animals. The reader (you! [singular]) will note the second person singu-lar pronoun in “tu analyse ça comment?” This is an example of the endless play on the difference between “tu” and “vous” that pervades the “Envois.”
Drawing Blanks
Creators: name: Naas, Michael
Publisher: name: punctum books
Year: 2017

description: The reader of The Post Card is surely to be excused for drawing a  blank  from  time  to  time.  It’s  not  easy  going  —  a  Derrida  text  rarely  is  —  and  “To  Speculate  —  on  ‘Freud’”  and  “Le  facteur  de  la vérité” are among Derrida’s most challenging works. But pa-tience and rereading almost always have their rewards when it comes to Derrida. However difficult these essays may be at first glance or at a first reading, they are not impenetrable, as some have  wanted  to  pretend,  and  multiple  readings  almost  always  yield  a  coherent  if  not  convincing  reading  of  Freud  or  Lacan  on themes such as repetition, legacy, language, the unconscious, or  the  relationship  between  psychoanalysis  and  philosophy.  Even if the reader winds up drawing a blank now and again, the goal  nonetheless  remains  and  should  remain  to  interpret  and  to understand, in a word, to gloss — the argument as well as the rhetoric, the organization as well as the themes, everything from the theses that are put forward to the language and terms used to  support  them.  To  arrive  at  a  reading  of  these  works  —  that  should  remain  the  goal  of  every  reader  who  enters  the  ring  or  the  arena  of  interpretation,  every  reader  who  agrees  to  going  postcard.

description: Using the recipe of arXiv:0902.4814, where all fake supersymmetric backgrounds of matter-coupled fake N=2, d=4 gauged supergravity were classified, we construct dynamical rotating black holes in an expanding FLRW universe. This is done for two different prepotentials that are both truncations of the stu model and correspond to just one vector multiplet. In this scenario, the cosmic expansion is driven by two U(1) gauge fields and by a complex scalar that rolls down its potential. Generically, the solutions of arXiv:0902.4814 are fibrations over a Gauduchon-Tod base space, and we make three different choices for this base, namely flat space, the three-sphere and the Berger sphere. In the first two cases, the black holes are determined by harmonic functions on the base, while in the last case they obey a deformed Laplace equation that contains the squashing parameter of the Berger sphere. This is the generalization to a cosmological context of the usual recipe in ungauged supergravity, where black holes are given in terms of harmonic functions on three-dimensional Euclidean space. The constructed solutions may be instrumental in addressing analytically questions like black hole collisions and violation of cosmic censorship.

Troubling Lines: The Process of Address in Derrida's The Post Card
Creators: name: Elmore, Rick
Publisher: name: punctum books
Year: 2017

description: There  is  a  line  in  The  Post  Card  that  has  always  bothered  me.  Now, to be clear, I do not hate this line. It does not keep me up at  night.  I  do  not  have  to  suppress  the  urge  to  burn  the  book  every  time  I  read  it.  But  I  have  never  understood  its  phrasing  or placement. It is, for me, in tension with the constellation of claims and concepts around which it circulates. This line comes in  the  second  entry  marked  6  June  1977  (PC, 16–17/20–22).  In  this  passage,  Derrida  gives  a  reading  of  the  postcard  that  in-spires his text. One will recall that the image on this card is of Socrates  seated  at  a  writing  desk,  pen  in  hand,  with  a  smaller  Plato standing behind him, seemingly dictating. Derrida spends the  majority  of  this  passage  analyzing  a  number  of  the  peculi-arities of this image (the positioning of the figures, the fact that it  is  Socrates  writing  and  not  Plato,  the  seeming  confusion  of  master  and  pupil,  teacher  and  student,  etc).  In  the  middle  of  this  analysis,  however,  Derrida  interjects  the  following  state-ment,  apparently  in  response  to  the  question,  “[t]o  whom  do  you  think  he  [Socrates]  writes?”  Derrida  states,  “[f ]or  me  it  is  always more important to know that [to whom one writes] than to know what is being written; moreover I think it amounts to the  same,  to  the  other  finally”  (PC,  17/21).  This  is  the  line  that  has always troubled me, particularly because of the privilege it grants  to  knowledge  of  addressees  over  that  of  content.  Allow  me to elaborate.

description: It is well known that a k-dimensional smooth surface in a Euclidean space cannot be tangent to a non-involutive distribution of k-dimensional planes. In this paper we discuss the extension of this statement to weaker notions of surfaces, namely integral and normal currents. We find out that integral currents behave to this regard exactly as smooth surfaces, while the behaviour of normal currents is rather multifaceted. This issue is strictly related to a geometric property of the boundary of currents, which is also discussed in details.

A formal method for identifying distinct states of variability in time-varying sources: SgrA* as an example

description: Continuously time variable sources are often characterized by their power spectral density and flux distribution. These quantities can undergo dramatic changes over time if the underlying physical processes change. However, some changes can be subtle and not distinguishable using standard statistical approaches. Here, we report a methodology that aims to identify distinct but similar states of time variability. We apply this method to the Galactic supermassive black hole, where 2.2 um flux is observed from a source associated with SgrA*, and where two distinct states have recently been suggested. Our approach is taken from mathematical finance and works with conditional flux density distributions that depend on the previous flux value. The discrete, unobserved (hidden) state variable is modeled as a stochastic process and the transition probabilities are inferred from the flux density time series. Using the most comprehensive data set to date, in which all Keck and a majority of the publicly available VLT data have been merged, we show that SgrA* is sufficiently described by a single intrinsic state. However the observed flux densities exhibit two states: a noise-dominated and a source-dominated one. Our methodology reported here will prove extremely useful to assess the effects of the putative gas cloud G2 that is on its way toward the black hole and might create a new state of variability.

Large deviations for stochastic nonlinear systems of slow-fast diffusions with non-Gaussian Lévy noises

description: We establish the large deviation principle for the slow variables in slow-fast dynamical system driven by both Brownian noises and Lévy noises. The fast variables evolve at much faster time scale than the slow variables, but they are fully inter-dependent. We study the asymptotics of the logarithmic functionals of the slow variables in the three regimes based on viscosity solutions to the Cauchy problem for a sequence of partial integro-differential equations. We also verify the comparison principle for the related Cauchy problem to show the existence and uniqueness of the limit for viscosity solutions.

description: We present improved methodology for including covariance matrices in the error budget of Baryon Oscillation Spectroscopic Survey (BOSS) galaxy clustering measurements, revisiting Data Release 9 (DR9) analyses, and describing a method that is used in DR10/11 analyses presented in companion papers. The precise analysis method adopted is becoming increasingly important, due to the precision that BOSS can now reach: even using as many as 600 mock catalogues to estimate covariance of 2-point clustering measurements can still lead to an increase in the errors of ~20%, depending on how the cosmological parameters of interest are measured. In this paper we extend previous work on this contribution to the error budget, deriving formulae for errors measured by integrating over the likelihood, and to the distribution of recovered best-fit parameters fitting the simulations also used to estimate the covariance matrix. Both are situations that previous analyses of BOSS have considered. We apply the formulae derived to Baryon Acoustic Oscillation (BAO) and Redshift-Space Distortion (RSD) measurements from BOSS in our companion papers. To further aid these analyses, we consider the optimum number of bins to use for 2-point measurements using the monopole power spectrum or correlation function for BAO, and the monopole and quadrupole moments of the correlation function for anisotropic-BAO and RSD measurements.

Postcard Telepathy

description: How  construe  commentary  on  a  postcard  that  is  specifically  figured  as  “a  pictorial  performative  which  never  ends”  (PC, 98/108)  —  especially  if  it  must  reckon,  at  the  same  time,  with  that   fragmentary   phantom   supplement   published   later   as   “Telepathy”1? I have been trying to read a bit of one of your post-cards, one of several dated 6 June 1977 (I note in passing that my own record of that day reveals that I too was in Oxford, and in the evening went to watch Yellow Submarine— Oxford can be a lonely place on a Monday night):What is going on under Socrates’ leg, do you recognize this object? It plunges under the waves made by the veils around the  plump  buttocks,  you  see  the  rounded  double,  improb-able enough, it plunges straight down, rigid, like the nose of a stingray, to electrocute the old man and analyze him under narcosis.  You  know  that  they  were  both  very  interested  in  this paralyzing animal. Would it make him write by paralyz-ing  him?  All  of  this,  that  I  do  not  know  or  do  not  yet  want  to see, also comes back from the bottom of the waters of my memory, a bit as if I had drawn or engraved the scene, from the  day  that,  in  an  Algiers  lycée  no  doubt,  I  first  heard  of  those two. Do people (I am not speaking of “philosophers” or of those who read Plato) realize to what extent this old couple has invaded our most private domesticity, mixing themselves up in everything, taking their part of everything, and mak-ing  us  attend  for  centuries  their  colossal  and  indefatigable  anaparalyses?

The  particular  artifact  in  figure  1,  sent  from  China  to  France  in  1912,  depicts  a  man  being  executed  by  lingchi  (凌遲  “slow  slicing,” or “death by a thousand cuts”). This postcard is one it-eration  of  the  West’s  persistent  horror  at  and  fascination  with  lingchi.  Another  example  is  a  post-execution  photograph  of  dismembered  body  parts  reproduced  in  Henry  Norman’s  The Peoples  and  Politics  of  the  Far  East  in  1895  (fig.  2).2  As  historians point out, foreign military occupation of Beijing following the Boxer Rebellion allowed Europeans, especially those able to afford  a  camera,  to  roam  the  country  more  or  less  at  will.  Im-ages  of  lingchi  executions  began  to  circulate  as  curiosities  and  mementos — especially in the form of postcards — in Europe.
RTF-steered binaural MVDR beamforming incorporating multiple external microphones

description: The binaural minimum-variance distortionless-response (BMVDR) beamformer is a well-known noise reduction algorithm that can be steered using the relative transfer function (RTF) vector of the desired speech source. Exploiting the availability of an external microphone that is spatially separated from the head-mounted microphones, an efficient method has been recently proposed to estimate the RTF vector in a diffuse noise field. When multiple external microphones are available, different RTF vector estimates can be obtained by using this method for each external microphone. In this paper, we propose several procedures to combine these RTF vector estimates, either by selecting the estimate corresponding to the highest input SNR, by averaging the estimates or by combining the estimates in order to maximize the output SNR of the BMVDR beamformer. Experimental results for a moving speaker and diffuse noise in a reverberant environment show that the output SNR-maximizing combination yields the largest binaural SNR improvement and also outperforms the state-of-the art covariance whitening method.

Ateleia/Autoimmunity

Publisher: name: punctum books
Year: 2017

description: I would like to highlight an important connection between Der-rida’s use of the term “autoimmunity” in his later work and the postal principle of The Post Card. Specifically, I want to point out that the notion of the stamp (stretching from “stamp” to “tim-bre”  and  the  “post  card”  itself  in  “Envois”),  which  resonates  in  the  associations  of  sending  at  the  heart  of  the  postal  principle  itself, connects to the logic of the immunis which generates “au-toimmunity.” The connection is articulated in the historical con-struction of the name of stamp collection, or love of the stamp as  “philately,”  which  is  constructed  with  the  help  of  the  Greek  ateleia. Both terms, ateleia and immunis, refer to tax exemption.
Power-enhanced leading-logarithmic QED corrections to $B_q \to μ^+μ^-$

description: We provide a systematic treatment of the previously discovered power-enhanced QED corrections to the leptonic decay $B_q\to μ^+μ^-$ ($q = d, s$) in the framework of soft-collinear effective theory (SCET). Employing two-step matching on SCET$_\text{I}$ and SCET$_\text{II}$, and the respective renormalization group equations, we sum the leading-logarithmic QED corrections and the mixed QED-QCD corrections to all orders in the couplings for the matrix element of the semileptonic weak effective operator $\sim Q_9$. We propose a treatment of the $B$-meson decay constant and light-cone distribution amplitude in the presence of process-specific QED corrections. Finally we include ultrasoft photon radiation and provide updated values of the non-radiative and radiative branching fractions of $B_q \to μ^+μ^-$ decay that include the double-logarithmic QED and QCD corrections.
