A comparative study of wormhole geometries under two different modified gravity formalism
In the current article, we discuss the wormhole geometries in two different gravity theories, namely
F
(
Q
,
T
)
gravity and
F
(
R
,
T
)
gravity. In these theories,
Q
is called a non-metricity scalar,
R
stands for the Ricci scalar, and
T
denotes the trace of the energy–momentum tensor (EMT). The main goal of this study is to comprehensively compare the properties of wormhole solutions within these two modified gravity frameworks by taking a particular shape function. The conducted analysis shows that the energy density is consistently positive for wormhole models in both gravity theories, while the radial pressure is positive for
F
(
Q
,
T
)
gravity and negative in
F
(
R
,
T
)
gravity. Furthermore, the tangential pressure shows reverse behavior in comparison to the radial pressure. By using the Tolman-Oppenheimer-Volkov (TOV) equation, the equilibrium aspect is also described, which indicates that hydrostatic force dominates anisotropic force in the case of
F
(
Q
,
T
)
gravity theory, while the reverse situation occurs in
F
(
R
,
T
)
gravity, i.e., anisotropic force dominates hydrostatic force. Moreover, using the concept of the exoticity parameter, we observed the presence of exotic matter at or near the throat in the case of
F
(
Q
,
T
)
gravity while matter distribution is exotic near the throat but normal matter far from the throat in
F
(
R
,
T
)
gravity case. In conclusion, precise wormhole models can be created with a potential NEC and DEC violation at the throat of both wormholes while having a positive energy density, i.e.,
ρ

Warp drive aerodynamics
A
bstract
In this work we analyse the potential for a warp drive spacetime to develop instabilities due to the presence of quantum matter. Particularly, we look for points of infinite blueshift (which are analogous to points of a black hole inner horizon, known for its semiclassical instability), and categorise them through the behaviour of geodesics in their vicinity. We find that warp-drive bubbles in dimension 2+1 or higher are in fact likely to be stable, as they generally contain only isolated points where divergences are approached, leading to a finite limit for the overall accumulation of destabilising energy. Furthermore, any semiclassical instabilities in the warp drive due to energy-density buildups can be further diminished with particular, more “aerodynamic” shapes and trajectories for the drive.

One Woman in a Hundred
Gifted harpist Edna Phillips (1907-2003) joined the Philadelphia Orchestra in 1930, becoming not only that ensemble's first female member but also the first woman to hold a principal position in a major American orchestra. Plucked from the Curtis Institute of Music in the midst of her studies, Phillips was only twenty-three years old when Leopold Stokowski, one of the twentieth century's most innovative and controversial conductors, named her principal harpist. This candid, colorful account traces Phillips's journey through the competitive realm of Philadelphia's virtuoso players, where she survived--and thrived--thanks to her undeniable talent, determination, and lively humor._x000B__x000B_Drawing on extensive interviews with Phillips, her family, and colleagues as well as archival sources, One Woman in a Hundred chronicles the training, aspirations, setbacks, and successes of this pioneering woman musician. Mary Sue Welsh recounts numerous insider stories of rehearsal and performance with Stokowski and other renowned conductors of the period such as Arturo Toscanini, Fritz Reiner, Otto Klemperer, Sir Thomas Beecham, and Eugene Ormandy. She also depicts Phillips's interactions with fellow performers, the orchestra management, and her teacher, the wily and brilliant Carlos Salzedo. Blessed with a nimble wit, Phillips navigated a plethora of challenges, ranging from false conductors' cues to the advances of the debonair Stokowski and others. She remained with the orchestra through some of its most exciting years from 1930 to 1946 and was instrumental in fostering harp performance, commissioning many significant contributions to the literature. _x000B__x000B_This portrait of Phillips's exceptional tenure with the Philadelphia Orchestra also reveals the behind-the-scenes life of a famous orchestra during a period in which Rachmaninoff declared it \"the finest orchestra the world has ever heard.\" Through Phillips's perceptive eyes, readers will watch as Stokowski melds his musicians into a marvelously flexible ensemble; world-class performers reach great heights and make embarrassing flubs; Greta Garbo comes to Philadelphia to observe her lover Leopold Stokowski at work; and the orchestra encounters the novel experience of recording for Walt Disney's Fantasia. A colorful glimpse into a world-class orchestra at the height of its glory, One Woman in a Hundred tells the fascinating story of one woman brave enough and strong enough to overcome historic barriers and pursue her dreams._x000B_

T-Duality and the Signature of 4-Dimensional Spacetime
This thesis is centered around the study of geometric aspects of string theory and supergravity. We will focus on N = 2, D= 4 supergravity theories in arbitrary spacetime signature. We will obtain these supergravity theories as Calabi-Yau compactifications of Hull’s exotic Type II theories. In ten dimensions these theories are related to each other via T-duality and S-duality. We will obtain the four dimensional duality web of theories as a projection of the ten-dimensional one. Moreover the T-duality relations between theories define maps, from the vectormultiplet geometries to the hypermultiplet geometries, called c-maps, which will be characterized and classified.We will then turn to the study of solutions of such theories. We will be interested in non-extremal black hole and cosmological solutions exhibiting planar symmetry. Such solutions will be T-dualized and we will interpret their behavior once embedded in string theory.
Dissertation
Revenant modernisms and the recurrence of Literary History
This essay suggests that literary production post-postmodernism has not progressed to something new, but rather has returned to quintessentially modernist anxieties and modes of expression––especially renewed faith in grand narratives. The argument draws upon and coalesces two theoretical texts to help identify what I term ‘revenant modernism’ as a “symbolic space” (Flatley, 2008: 32) where a sort of “secular re-enchantment” (Landy & Saler, 2009: 2) remains possible: Jonathan Flatley’s Affective mapping: Melancholia and the politics of modernism (2008) and The re-enchantment of the world: Secular magic in a rational age (2009) by Joshua Landy and Michael Saler. I then examine two recent novels––Will Self’s Umbrella (2012) and Eimear McBride’s A girl is a half-formed thing (2014)––as evidence of this return. Along the way, I tie both of these novels back to their stated modernist influence (James Joyce’s Ulysses [1993]) in order to show how Self and McBride’s fiction borrows from Joyce’s particular brand of postcolonial modernism.

Materializing a Cyborg's Manifesto
After catastrophic spring flooding throughout North America, 312 tornadoes in the southcentral United States in a seventy-two-hour period in April, a historically unprecedented summer drought in Texas, and a tropical hurricane in late August that devastates infrastructures in the state of Vermont and floods downtown Paterson, New Jersey, with fourteen feet of water, a candidate for U.S. president publicly states that climate change is undocumented science. Built partially on a decade of research tracking the post-World War II transformation of biology's key matters into militarized command- communication- control and information systems (1994, 243), Haraway s worldly cyborg in 1985 stages a feminist historical materialist re-visioning of how social relations of science and technology complexly matter within a networked series of local/ global transformations that the essay maps with extraordinary intellectual ambition and acuity.

The Technological Sublime in the Fiction of the New South
The romantic imagery of the natural sublime (those repeated experiences of awe and wonder, often tinged with an element of terror, which people have had when confronted with particular natural sites) is applied to a historical parade of technologies with purportedly transcendent powers.3 In the initial phase of the technological sublime of the nineteenth and early twentieth centuries, David Nye observes, massive man-made objects such as dams, buildings, and bridges were described in awestruck terms as triumphs over the physical powers of nature, while the railroad, the steamboat, and the telegraph manifested the triumph of machines . . . over space and time. Reed stares at his computer's screensaver, exploring sublime images from the Hubble Space Telescope: [W]hen he contemplated a spiral galaxy or a massive globular star cluster, or even something as common as a comet, he swelled with imagination.
