description: A new type of spectroscopy for high-resolution studies of spin waves that relies on resonant scattering of hard x-rays is introduced. The energy transfer in the scattering process is encoded in the precession of the polarization vector of the scattered photons. Thus, the energy resolution of such a spectroscopy is independent of the bandwidth of the probing radiation. The measured quantity resembles the intermediate scattering function of the magnetic excitations in the sample. At pulsed x-ray sources, especially x-ray lasers, the proposed technique allows to take single-shot spectra of the magnetic dynamics. The method opens new avenues to study low-energy non-equilibrium magnetic processes in a pump-probe setup.

description: The Quadratic Assignment Problem (QAP) is one of the models used for the multi-row layout problem with facilities of equal area. There are a set of n facilities and a set of n locations. For each pair of locations, a distance is specified and for each pair of facilities a weight or flow is specified (e.g., the amount of supplies transported between the two facilities). The problem is to assign all facilities to different locations with the aim of minimizing the sum of the distances multiplied by the corresponding flows. The QAP is among the most difficult NP-hard combinatorial optimization problems. Because of this, this paper presents an efficient Genetic algorithm (GA) to solve this problem in reasonable time. For validation the proposed GA some examples are selected from QAP library. The obtained results in reasonable time show the efficiency of proposed GA.

Robert Smithson's Abstract Geology: Revisiting the Premonitory Politics of the Triassic

description: In  response  to  an  artist  symposium  question  regarding  the  “deepening  political  crisis  in  America,”  Robert  Smithson  published  a  piece  in  Artforum,  September  1970,  titled  “Art  and  the Political Whirlpool or the Politics of Disgust.” In it, he said: My ‘position’ is one of sinking into an awareness of global squalor and futility. The rat of poli-tics always gnaws at the cheese of art. The trap is set. If there’s an original curse, then politics has  something  to  do  with  it.  Direct  political  action  becomes  a  matter  of  trying  to  pick  poi-son  out  of  boiling  stew.  The  pain  of  this  experience  accelerates  the  need  for  more  and  more  actions.1Later that same year, when asked about his political stance by Philip Leider, Smithson re-marked, “I’m interested in the politics of the Triassic period.” In an earlier essay, “The Crystal Land” (1966), Smithson suggested some of the sedimentary compositions at stake in a geo-artistic politics:Brian H. Mason, in his fascinating booklet, Trap Rock Minerals of New Jersey, speaks of the “Triassic sedimentary rocks of the Neward series,” which are related to those of the Palisades.

description: 473 Inches at 60 Frames per Secondwas a site-specific sculptural installation with reference to the Wisconsin Glacial Episode, a glacial period that left Minnesota and parts of Wisconsin covered with numerous lakes and rivers. At the Soap Factory in Minneapolis, MN, Wade Kava-naugh and Stephen B. Nguyen created a two-part artwork that consisted of a glacial ice sheet made  of  textured  white  kraft  paper  and  a  time  lapse  video.  The  two  works  were  physically  and temporally downscaled to human scale. The sculpture was created in a way that the final stop-motion  documentation  read  as  if  the  glacier  was  advancing  over  a  stone  canyon  made  of brown kraft paper. The time lapse video shows the paper glacier advancing at a rate of 473 inches  at  60  frames  per  second,  a  metric  that  shifts  physical  scale  and  time,  from  glacial  to  human

description: (Abridged) With infrared interferometry it is possible to resolve the nuclear dust distributions that are commonly associated with the dusty torus in active galactic nuclei (AGN). The Circinus galaxy hosts the closest Seyfert 2 nucleus and previous interferometric observations have shown that its nuclear dust emission is well resolved. To better constrain the dust morphology in this active nucleus, extensive new observations were carried out with MIDI at the Very Large Telescope Interferometer. The emission is distributed in two distinct components: a disk-like emission component with a size of ~ 0.2 $\times$ 1.1 pc and an extended component with a size of ~ 0.8 $\times$ 1.9 pc. The disk-like component is elongated along PA ~ 46° and oriented perpendicular to the ionisation cone and outflow. The extended component is elongated along PA ~ 107°, roughly perpendicular to the disk component and thus in polar direction. It is interpreted as emission from the inner funnel of an extended dust distribution and shows a strong increase in the extinction towards the south-east. We find no evidence of an increase in the temperature of the dust towards the centre. From this we infer that most of the near-infrared emission probably comes from parsec scales as well. We further argue that the disk component alone is not sufficient to provide the necessary obscuration and collimation of the ionising radiation and outflow. The material responsible for this must instead be located on scales of ~ 1 pc, surrounding the disk. The clear separation of the dust emission into a disk-like emitter and a polar elongated source will require an adaptation of our current understanding of the dust emission in AGN. The lack of any evidence of an increase in the dust temperature towards the centre poses a challenge for the picture of a centrally heated dust distribution.

description: The radio-loud quasar SDSS J114657.79+403708.6 at a redshift z=5.0 is one of the most distant radio-loud objects. The IR-optical luminosity and spectrum suggest that its black hole has a very large mass: M=(5+-1)x 1e9 Msun. The radio-loudness (ratio of the radio to optical flux) of the source is large (around 100), suggesting that the source is viewed at small angles from the jet axis, and could be a blazar. The X-ray observations fully confirm this hypothesis, due to the high level and hardness of the flux. This makes SDSS J114657.79+403708.6 the third most distant blazar known, after Q0906+693 (z=5.47) and B2 1023+25 (z=5.3). Among those, SDSS J114657.79+403708.6 has the largest black hole mass, setting interesting constraints on the mass function of heavy (larger than one billion solar masses) black holes at high redshifts.

description: Biased-coin designs are used in clinical trials to allocate treatments with some randomness while maintaining approximately equal allocation. More recent rules are compared with Efron's [Biometrika 58 (1971) 403-417] biased-coin rule and extended to allow balance over covariates. The main properties are loss of information, due to imbalance, and selection bias. Theoretical results, mostly large sample, are assembled and assessed by small-sample simulations. The properties of the rules fall into three clear categories. A Bayesian rule is shown to have appealing properties; at the cost of slight imbalance, bias is virtually eliminated for large samples.

X-ray emission

description: Cool stars on the main sequence generate X-rays from coronal activity, powered by a convective dynamo. With increasing temperature, the convective envelope becomes smaller and X-ray emission fainter, so some cool star must be the “hottest cool star” before emission ends. We present Chandra/HRC-I observations of four single stars with early A spectral types. Only the coolest star of this sample, \(\tau^3\) Eri (Teff = 8000 K), is detected with log(LX/Lbol)=-7.6, while the three hotter stars (Teff > 8100 K), namely \(\delta\) Leo, \(\beta\) Leo, and \(\iota\) Cen, remain undetected with upper limits log(LX/Lbol)<-8.4. The drop in X-ray emission thus occurs a in narrow range of effective temperatures around 8100 K and matches the end of activity in the C III and O VI transition region lines. Based on our observations, \(\tau^3\) Eri might well be the hottest star that still shows cool-star like coronal activity.

description: Experimental analyses often use jet binning to distinguish between different kinematic regimes and separate contributions from background processes. To accurately model theoretical uncertainties in these measurements, a consistent description of the jet bins is required. We present a complete framework for the combination of resummed results for production processes in different exclusive jet bins, focusing on Higgs production in gluon fusion as an example. We extend the resummation of the Higgs + 1-jet cross section into the challenging low transverse momentum region, lowering the uncertainties considerably. We provide combined predictions with resummation for cross sections in the Higgs + 0-jet and Higgs + 1-jet bins, and give an improved theory covariance matrix for use in experimental studies. We estimate that the relevant theoretical uncertainties on the signal strength in the Higgs to WW analysis are reduced by nearly a factor of 2 compared to the current value.

description: These images are from Drawn to the Edge, my solo exhibition at the New Orleans Museum of Art (June 15 to September 9, 2012). In many ways the work is an attempt to capture time—to ex-plore how today’s New Orleans is profoundly connected to its past and to consider how quickly we seem to be running out of time.During a six-week residency this spring at A Studio in the Woods (ASITW), which is located on  a  bend  of  the  Mississippi  River  just  east  of  the  city  center,  I  looked  atthe  history  of  the  place, focusing my research on the city and its relationship with the river, through both the slow processes of geologic time and the rapid changes of the 20th and 21st centuries. I quickly came to  see  that  New  Orleans’  history  is  fundamentally  connected  to  its  underlying  geology,  more  so than any other place I’ve ever been. Five thousand years ago, there was no land where New Orleans is today – it was all open water. Slowly over the millennia, the alluvial plain of southern Louisiana was created as the Mississippi River dropped sediment along its meandering path to the Gulf of Mexico.

description: Aim: A series of semicarbazone and thiosemicarbazone-tailed hybrids comprising pyrazole and acetylisoxazoline were prepared from (R)-carvone and characterized by technique spectroscopies Nuclear Magnetic Resonance (NMR), IR and High-Resolution Mass Spectrometry. Density Functional Theory (DFT) determined the structural parameters. Their cytotoxic activity was evaluated in vitro against four human cancer cell lines. Methods & results: All the studied semi and thiosemicarbazone demonstrate a promising potential as anticancer agents. The mechanism of action of these compounds involves apoptosis in HT-1080 cells, supported by an increase in the level of caspase-3/7 activity, which also arrests the cell cycle in the G0/G1 phase. Molecular docking studies were performed to establish the potential of the most active compounds 4a and 5a. ADMET analysis showed appropriate pharmacokinetic properties, allowing structure prediction for anticancer activity. A series of semicarbazone and thiosemicarbazone-tailed hybrids comprising pyrazole and acetylisoxazolin were synthesized from natural bioactive (R)-carvone and characterized by spectroscopic techniques (1H- and 13C- NMR) and High-Resolution Mass Spectrometry. Chemical reactivity and chemical stability parameters were observed via density functional theory calculations (DFT). Compound 4a and 5a represents significant (cytotoxicity) IC50 values 13.41 ± 0.44 μM and 14.34 ± 0.56 μM respectively against HT-1080 cells using the MTT assay. The mechanism of action by which the most active derivatives 4a and 5a exert their effect suggested that they may induce apoptosis through activation of caspase-3/7. Molecular docking results were supported study.
Suppressing defect production during passage through a quantum critical point

description: We show that a closed quantum system driven through a quantum critical point with two rates $ω_1$ (which controls its proximity to the quantum critical point) and $ω_2$ (which controls the dispersion of the low-energy quasiparticles at the critical point) exhibits novel scaling laws for defect density $n$ and residual energy $Q$. We demonstrate suppression of both $n$ and $Q$ with increasing $ω_2$ leading to an alternate route to achieving near-adiabaticity in a finite time for a quantum system during its passage through a critical point. We provide an exact solution for such dynamics with linear drive protocols applied to a class of integrable models, supplement this solution with scaling arguments applicable to generic many-body Hamiltonians, and discuss specific models and experimental systems where our theory may be tested.

The Nuclear Present

description: On  September  29th,  2009,  I  was  about  to  begin  a  pilgrimage  to  a  remote  location  in  the  Southwestern desert. With my mother as navigator, my plan was to drive from my home state of  Montana  to  the  Trinity  Nuclear  Test  Site,  located  within  the  White  Sands  Missile  Range  between Alamogordo and Soccorro, New Mexico. The United States military opens the Trinity Test Site to the general public two times a year, in the beginning of October and April.  On July 16, 1945, the first plutonium-based atomic weapon was detonated on a remote location in the New Mexican desert. The subsequent explosion of “The Gadget” was described as a blinding light of golden, purple, violet, gray, and blue, lighting up the early desert morning as if it were high noon. At ten miles away, spectators required dark sunglasses to look upon the explosion without damage to their eyes. The  Trinity  explosion  did  not  produce  a  crater  at  ground  zero,  but  left  behind  a  small  lake  of  greenish  glass,  dubbed  “trinitite.”  It  is  theorized  that  the  intense  heat  generated  by  the  nuclear  fireball  (in  excess  of  14,000  degrees  Fahrenheit)  liquefied  the  desert  sand  floor  into  glass  and  sucked  the  material  into  the  emergent  mushroom  cloud.    At  such  high  force  and  temperature,  the  vaporized  glass  behaves  like  water  in  a  typical  cloud:  it  collects  in  the  mushroom  cloud,  aggregates  and  falls  back  to  the  earth  as  a  shower  of  molten  glass.  The  extant  body  of  glass,  trinitite,  was  the  only  material  that  remained  at  ground  zero—The  Gadget and the metal scaffolding holding the device were obliterated.

description: There are numerous examples in the literature of low-mass stars (<0.3 Msol) that have radii larger than those predicted by theoretical models. This “radius inflation” problem indicates missing physics in current stellar models that has a direct impact on the analysis and interpretation of observations for transiting exoplanet systems orbiting low-mass stars. Though there have been many proposed causes of this problem such as increased stellar magnetism, metallicity or tidal interactions there has been no definitive conclusion drawn in the literature. To address this problem, we have used the exoplanetary follow-up satellite CHEOPS to obtain high-precision photometry for a sample of 20 eclipsing binaries. Our targets are low mass stars orbiting solar-type stars with a range of metallicities. We seek to provide a sample of homogeneous and precise radius and effective temperature measurements and search them for any possible trends of radius inflation with metallicity, age, etc. Early results include targets that both do and do not show signs of radius inflation, with hints of a trend for metal-rich stars to be more likely to show radius inflation.

Most  are  repositories  for  the  remains  of  uranium  mills,  processing  facilities,  weapons  plants,  and  contaminated  tailings,  bulldozed  into  engineered  isolation  mounds  designed to limit contact with their surroundings for hundreds of years. There are dozens of these mounds, across the country from Pennsylvania to Arizona, built mostly by the Depart-ment of Energy, and maintained by their Legacy Management office.These disposal mounds are generally low, rectilinear piles with flat, sloping tops – terrestrial umbrellas,  keeping  moisture  out  of  the  pile  as  much  as  possible.  In  arid  environments,  the  outer layer is a coating of coarse riprap rock, a dead space where nothing grows, where no soil forms,  and  no  roots  take  hold  that  could  pierce  the  radioactive  core.  This  tough  skin  allows  occasional rains to pass through it to the next layer, a low-permeability clayey mixture a few feet thick. Water drains off to the side of the pile through channels at the base held in place with more layers of crushed stone.

The initiative dates back to 2003 when I led an experimental project supported by the Presidency of Brazil. At that time, we issued paper currency in a small, touristic village in the Northeast Region which stimulated local cultural projects. But it was only in 2009 that the Central Bank of Brazil acknowledged “social currencies” as a legitimate economic agenda, calling for  more  debate  at  the  Financial  Inclusion  Forum.  This  year,  the  monetary  authorities organized a second forum that also opened the room to discus-sions on mobile payment systems and new perspectives on poverty allevia-tion via State subsidies. The Ministry of Culture funded the “Creative Cur-rencies” project in 2009–2010 and our next stage in this discovery process is to be supported by the National Social and Economic Development Bank (bndes). In short, there is genuine interest among public officials in different areas and public funding for social currencies is on the rise in Brazil.

description: Quantum tunnelling is a common fundamental quantum-mechanical phenomenon that originates from the wave-like characteristics of quantum particles. Although the quantum-tunnelling effect was first observed 85 years ago, some questions regarding the dynamics of quantum tunnelling remain unresolved. Here, we realise a quantum-tunnelling system using two-dimensional ionic structures in a linear Paul trap. We demonstrate that the charged particles in this quantum-tunnelling system are coupled to the vector potential of a magnetic field throughout the entire process, even during quantum tunnelling, as indicated by the manifestation of the Aharonov-Bohm effect in this system. The tunnelling rate of the structures periodically depends on the strength of the magnetic field, whose period is the same as the magnetic-flux quantum $ϕ_0$ through the rotor [($0.99 \pm 0.07)\times ϕ_0$].

description: Understanding the superconducting proximity effect on the surface of a topological insulator is of critical importance in realizing topological superconductivity and Majorana fermions in solid state settings. We fabricate delicate heterostructure samples between topological insulator (TI) Bi2Se3 thin film and high temperature superconductor Bi2Sr2CaCu2O8+ (Tc ~ 91 K). Using angle-resolved photoemission spectroscopy, we probe the electronic structure and the possible existence of superconducting gap on the top surface of Bi2Se3 thin films. Our systematic data show no significant proximity-induced superconducting gap in the topological surface states with sample temperature down to 10 K (<<91 K) and with a confidence level of sub 5 meV, much smaller than what have been claimed previously, which indicates the near absence of the proximity-induced superconductivity on the TI surface. Our momentum space imaging provides evidence for the coexistence of two crystalline phases in Bi2Se3/Bi2Sr2CaCu2O8+ samples, which we argue to be due to the strong mismatch of lattice crystalline symmetries. Our data identify the major contributors in reducing the proximity-induced superconducting gap below the meV range, including the lack of momentum space overlap between the Bi2Se3 and Bi2Sr2CaCu2O8+ Fermi surfaces, the strong mismatch of lattice crystalline symmetries and superconducting pairing symmetries, as well as the very short superconducting coherence length in Bi2Sr2CaCu2O8+. Our ARPES studies not only provide critical momentum space insights into the Bi2Se3/Bi2Sr2CaCu2O8+ heterostructure, but also set an upper bound on the proximity induced gap for realizing a Majorana fermion condition in this system, which may be further destabilized by the d-wave nodes dominated in a cuprate superconductor.

Each  brain  region’s  cells  possess  an  electrical  signature.  During  recordings electrical signals are transformed into sound to facilitate auditory identification of cells during a process called “mapping.” Mapping is an important step in successfully identifying and localizing the appropriate target site in the brain for an experimental therapeutic proce-dure  called  deep  brain  stimulation  which  has  been  used  for  patients  with  movement disorders and, more recently, for patients with psychiatric disor-ders.
The Fragment as a Unit of Prose Composition: an Introduction
Creators: name: Segal, Ben
Publisher: name: punctum books
Year: 2012

description: The fragment, the note, the idea, the aphorism even: there are many names and as many uses for such small shards of free-floating text. Typi-cally fragments are less works than gestures, arrows pointing in the direc-tion a person might research, meditate on or develop. Unlike paragraphs or sentences, they do not flow directly from and into their bordering text. Instead they are independent, defined by their singularity, by the white space that encases them on a page – even when they are cobbled together and marshaled into service as the contents of a book. Still, though not exceedingly common, books of fragments (or notes or what-have-yous) do exist. However they are labeled, the very aloof-ness of disconnected micro-texts allows them certain privileges and pos-sibilities that a writer can employ and exploit. In such instances, the book of fragments may, almost paradoxically, gain a coherence as a singular work, all the more satisfying for its fractures.Two such books are Maggie Nelson’s blUetS and Evan Lavender-Smith’s From Old Notebooks. We are pleased to present a series of excerpts from each of these books, a selection of ‘outtakes’ – fragments that did not make it into the final manuscripts – from each, and short interviews with both Nelson and Lavender-Smith about the fragment as a literary device
Mad Speculation and Absolute Inhumanism: Lovecraft, Ligotti, and the Weirding of Philosophy

description: I want to propose, as a trajectory into the philosophically weird, an absurd theoretical claim and pursue it, or perhaps more accurately, construct it as I point to it, collecting the ground work behind me like the Perpetual Train from  China  Miéville’s  Iron  Council  which  puts  down  track  as  it  moves  re-claiming it along the way. The strange trajectory is the following: Kant’s criti-cal philosophy and much of continental philosophy which has followed, has been a defense against horror and madness. Kant’s prohibition on specula-tive metaphysics such as dogmatic metaphysics and transcendental realism, on thinking beyond the imposition of transcendental and moral constraints, has been challenged by numerous figures proceeding him. One of the more interesting critiques of Kant comes from the mad black Deleuzianism of Nick Land  stating,  “Kant’s  critical  philosophy  is  the  most  elaborate  fit  of  panic  in the history of the Earth.”And while Alain Badiou would certainly be op-posed to the libidinal investments of Land’s Deleuzo-Guattarian thought, he is likewise critical of Kant’s normative thought-bureaucracies:Kant is the one author for whom I cannot feel any kinship. Everything in him exasperates me, above all his legalism – always asking Quid Juris?Or “Haven’t you crossed the limit?” – combined, as in today’s United States, with a religiosity that is all the more dismal in that it is both omnipresent and vague. The critical machinery he set up has enduringly poisoned philosophy, while giving great succour to the academy, which loves nothing more than to rap the knuckles of the overambitious [...]. That is how I understand the truth of Monique David-Menard’s reflec-tions on the properly psychotic origins of Kantianism (La Folie dans la raison pure [Paris: Vrin, 1990]). I am persuaded that the whole of the critical enterprise is set up to to shield against the tempting symptom represented by the seer Swedenborg, or against ‘diseases of the head’, as Kant puts it.

description: Gravitational instantons with NUT charge are magnetic monopoles upon dimensional reduction. We determine whether NUT charge can proliferate via the Polyakov mechanism and partially screen gravitational interactions. In semiclassical Einstein gravity, Taub-NUT instantons experience a universal attractive force in the path integral that prevents proliferation. This attraction further leads to semiclassical clumping instabilities, similar to the known instabilities of hot flat space and the Kaluza-Klein vacuum. Beyond pure Einstein gravity, NUT proliferation depends on the following question: is the mass of a gravitational instanton in the theory always greater than its NUT charge? Using spinorial methods we show that the answer to this question is `yes' if all matter fields obey a natural Euclidean energy condition. Therefore, the attractive force between instantons in the path integral wins out and gravity is dynamically protected against screening. Semiclassical gravity with a compactified circle can be self-consistently quantum ordered, at the cost of suffering from clumping instabilities.

description: A recent cross-correlation between the SDSS DR7 White Dwarf Catalog with the Wide-Field Infrared Survey Explorer ($WISE$) all-sky photometry at 3.4, 4.6, 12, and 22 microns performed by Debes et al. (2011) resulted in the discovery of 52 candidate dusty white dwarfs (WDs). The 6'' $WISE$ beam allows for the possibility that many of the excesses exhibited by these WDs may be due to contamination from a nearby source, however. We present MMT$+$SWIRC $J$- and $H$-band imaging observations (0.5-1.5'' PSF) of 16 of these candidate dusty WDs and confirm that four have spectral energy distributions (SEDs) consistent with a dusty disk and are not accompanied by a nearby source contaminant. The remaining 12 WDs have contaminated $WISE$ photometry and SEDs inconsistent with a dusty disk when the contaminating sources are not included in the photometry measurements. We find the frequency of disks around single WDs in the $WISE$ $\cap$ SDSS sample to be 2.6-4.1%. One of the four new dusty WDs has a mass of $1.04 M_{\odot}$ (progenitor mass $5.4 M_{\odot}$) and its discovery offers the first confirmation that massive WDs (and their massive progenitor stars) host planetary systems.

Relativistic Pair Beams from TeV Blazars: A Source of Reprocessed GeV Emission rather than IGM Heating

description: The interaction of TeV photons from blazars with the extragalactic background light produces a relativistic beam of electron-positron pairs streaming through the intergalactic medium (IGM). The fate of the beam energy is uncertain. By means of two- and three-dimensional particle-in-cell simulations, we study the non-linear evolution of dilute ultra-relativistic pair beams propagating through the IGM. We explore a wide range of beam Lorentz factors gamma_b>>1 and beam-to-plasma density ratios alpha<<1, so that our results can be extrapolated to the extreme parameters of blazar-induced beams (gamma_b~10^6 and alpha~10^(-15), for the most powerful blazars). For cold beams, we show that the oblique instability governs the early stages of evolution, but its exponential growth terminates - due to self-heating of the beam in the transverse direction - when only a negligible fraction ~(alpha/gamma_b)^(1/3)~10^(-7) of the beam energy has been transferred to the IGM plasma. Further relaxation of the beam proceeds through quasi-longitudinal modes, until the momentum dispersion in the direction of propagation saturates at DeltaP_{b,parallel}/gamma_b m_e c ~ 0.2. This corresponds to a fraction ~10% of the beam energy being ultimately transferred to the IGM plasma, irrespective of gamma_b or alpha. If the initial dispersion in beam momentum satisfies DeltaP_{b,parallel}/gamma_b m_e c > 0.2 (as typically expected for blazar-induced beams), the fraction of beam energy deposited into the IGM is much smaller than ~10%. It follows that at least ~90% of the beam energy is still available to power the GeV emission produced by inverse Compton up-scattering of the Cosmic Microwave Background by the beam pairs.

An Inhuman Fiction of Forces

description: ‘The Domain of Arnheim’ is a strange story by Edgar Allan Poe, in which a young man who inherits an in-credible fortune decides to spend it, not on buying art but on fashioning a landscape. Poe also imagines the Earth seen from space as itself a complete work of art. He anticipates the real ends of modernism. Is not the totality of all our endeavors, all our so-cial relations, tending towards the making over of the planet as a total work of art? This theme of a secular, aesthetic  destiny  has  its  roots  in  Romanticism,  but lately it has lost its more optimistic cast. What if the work of art into which the word turns excluded the presence of its own makers? What if its creation de-stroys the biological possibility of human life on the planet?

description: Analytical solutions for time-inhomogeneous linear birth-death processes with immigration are derived. While time-inhomogeneous linear birth-death processes without immigration have been studied by using a generating function approach, the processes with immigration are here analyzed by Lie algebraic discussions. As a result, a restriction for time-inhomogeneity of the birth-death process is understood from the viewpoint of the finiteness of the dimensionality of the Lie algebra.

description: In  1964,  the  horror  and  fantasy  author  Fritz  Leiber published  a  short  story  entitled  “Black  Gondolier,” which appeared in the Arkham House anthology Over the Edge, and was subsequently reprinted in the Ace Double volume Night Monsters. In this story, an un-named narrator tells of the mysterious disappearance of his friend Daloway, a recluse and autodidact living nearby  oil  fields  in  southern  California.  Daloway,  it seems, began to develop a bizarre and unnatural fascination with oil—not just as a natural resource, and not just as something of geopolitical value, but with oil in itself as an ancient and enigmatic manifestation of the hidden  world.  Over  time  Daloway’s  conversations with the narrator begin to take on the form of mystical visions, described by Daloway as a kind of gothic, fu-nereal ooze:.  .  .  that  black  and  nefarious  essence  of  all life that had ever been, constituting in fact a great deep-digged black graveyard of the ul-timate eldritch past with blackest ghosts, oil had waited for hundreds of millions of years, dreaming  its  black  dreams,  sluggishly  puls-ing beneath Earth’s stony skin, quivering in lightless pools roofed with marsh gas and in top-filled rocky tanks and coursing through a myriad channels . . .
