'Beyond, both the Old World, and the New': Authority and Knowledge in the works of Francis Bacon, with special reference to the New Atlantis
No full textPhDThis study investigates the role of authority in the works of Francis Bacon,
arguing that the issue of authority provides not only an interpretation of New
Atlantis, but an important structural component of his body of works. From
the first manifestation of his philosophical project to his last works of natural
history, authority is an all-pervasive issue - the authority of nature, of
scripture, of the named author, and how authority functions in the
dissemination of natural knowledge. Chapter one argues that the publication
of New Atlantis alongside Sylva sylvarum in 1626/7 was more the result of
William Rawley's need to assert his own authority as the protector and
disseminator of Bacon's textual legacy than an appreciation of the work's own
qualities. Chapter two considers Bacon's views of history and time,
suggesting that Bacon not only conceived of a new, progressive mode of
historical time which would allow for the assertion of a textual authority based
on the records of a civilisation unbroken by the vicissitudes of time, but that
he figured these theories in New Atlantis. Chapter three argues that Bacon
used theology both as defence and imperative to his intellectual programme,
while his attempt to move beyond the deterministic, Calvinist world-view to
allow for multiple possible futures, or `chance': Bacon could then present
experiment as the way of eliminating chance, in order to accelerate the rate of
new discovery. Chapter four investigates Bacon's manipulations of textual
authority, from the early rehearsals of the Instauratio magna to the
performance of reliability in print in Sylva sylvarum. Finally, the afterword
seeks to suggest that the New Atlantis hinges on the issues of authority with
which Bacon engaged throughout his career and writings: in the issue of
authority, Francis Bacon found the beginning and the end of his philosophy
BACON: Improving Broadcast Audio Authentication
No full textBluetooth's LE Audio, particularly broadcast audio, is at the forefront of becoming the de facto standard for immersive audio applications in public venues. Nevertheless, the security of the transmitted audio data is solely based on a passkey (Broadcast_Code) shared between all (including possibly malicious) receiver devices, leaving many envisaged applications vulnerable to impersonation as well as denial-of-service attacks. In order to address these vulnerabilities, we present BACON, a novel Bluetooth core specification-compliant mechanism for the authentication of Broadcast Isochronous Groups (BIGs). Authenticated BIGs are able to provide data authenticity for broadcast isochronous streams as well as control subevents used to disseminate control information to all receiver devices in the communication range. With BACON, we are the first to outline a mechanism that protects against attacks on broadcast audio applications while being small enough to fit on resource-constrained devices thanks to the underlying protocol's lightweight symmetric cryptography
Endogenous N-nitroso compounds, and their precursors, present in bacon, do not initiate or promote aberrant crypt foci in the colon of rats
No full textProcessed meat intake is associated with increased risk of colorectal cancer. This association may be explained by the endogenous formation of N-nitroso compounds (NOC). The hypothesis that meat intake can increase fecal NOC levels and colon carcinogenesis was tested in 175 Fischer 344 rats. Initiation was assessed by the number of aberrant crypt foci (ACF) in the colon of rats 45 days after the start of a high-fat bacon-based diet. Promotion was assessed by the multiplicity of ACF (crypts per ACF) in rats given experimental diets for 100 days starting 7 days after an azoxymethane injection. Three promotion studies were done, each in 5 groups of 10 rats, whose diets contained 7%, 14%, or 28% fat. Tested meats were bacon, pork, chicken, and beef. Fecal and dietary NOC were assayed by thermal energy analysis. Results show that feces from rats fed bacon-based diets contained 10-20 times more NOC than feces from control rats fed a casein-based diet (all p < 0.0001 in 4 studies). In bacon-fed rats, the amount of NOC input (diet) and output (feces) was similar. Rats fed a diet based on beef, pork, or chicken meat had less fecal NOC than controls (most p < 0.01). No ACF were detected in the colon of bacon-fed uninitiated rats. After azoxymethane injection, unprocessed but cooked meat-based diets did not change the number of ACF or the ACF multiplicity compared with control rats. In contrast, the bacon-based diet consistently reduced the number of large ACF per rat and the ACF multiplicity in the three promotion studies by 12%, 17%, and 20% (all p < 0.01). Results suggest that NOC from dietary bacon would not enhance colon carcinogenesis in rats
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
RRS James Cook Cruise 30, 26 Dec 2008-30 Jan 2009. Antarctic Deep Water Rates of Export (ANDREX)
No full textThis report describes scientific activities on RRS James Cook cruise 30, “ANDREX”, westwards from 30°E and in the vicinity of latitude 60°S, between late December 2008 and late January 2009. The cruise was terminated about halfway through by a medical emergency. Hydrographic work comprised 27 CTD/LADCP stations. Water samples were captured for measurement of salinity, dissolved oxygen, inorganic nutrients, oxygen isotope fraction, chlorofluorocarbons and sulphur hexafluoride, dissolved inorganic carbon and alkalinity, helium / tritium / noble gases and radiocarbon. Underway measurements comprised navigation, currents (ADCP), meteorology, and sea surface temperature and salinity. The remainder of the hydrographic section was executed a year later on RRS James Clark Ross, cruise JR239
Philosophy According to Tacitus: Francis Bacon and the Inquiry into the Limits of Human Self-Delusion
No full textBacon belonged to a cultural milieu that, between the sixteenth and the seventeenth centuries, proved to be especially receptive to infuences coming from such continental authors as Machiavelli, Bodin, Duplessis-Mornay, Hotman, and, through Lipsius, a particular brand of Stoicism tinged with Tacitean motifs. Within the broader question of Tacitus’ infuence on Tudor and Stuart culture, this article focuses on the issue of how Bacon’s characteristic insistence on the powers of the imagination (fingere) and of belief (credere) in shaping human history may have infuenced his view that human beings suffer from an innate tendency to self-delusion
The Rossby radius in the Arctic Ocean
No full textThe first (and second) baroclinic deformation (or Rossby) radii are presented north of ~60° N, focusing on deep basins and shelf seas in the high Arctic Ocean, the Nordic seas, Baffin Bay, Hudson Bay and the Canadian Arctic Archipelago, derived from climatological ocean data. In the high Arctic Ocean, the first Rossby radius increases from ~5 km in the Nansen Basin to ~15 km in the central Canadian Basin. In the shelf seas and elsewhere, values are low (1–7 km), reflecting weak density stratification, shallow water, or both. Seasonality strongly impacts the Rossby radius only in shallow seas, where winter homogenization of the water column can reduce it to below 1 km. Greater detail is seen in the output from an ice–ocean general circulation model, of higher resolution than the climatology. To assess the impact of secular variability, 10 years (2003–2012) of hydrographic stations along 150° W in the Beaufort Gyre are also analysed. The first-mode Rossby radius increases over this period by ~20%. Finally, we review the observed scales of Arctic Ocean eddies

A possible mechanism of superconductivity in high-T-c cuprates
No full textThis paper derives a generic T-c formula by using the long-range phase coherence condition in quantum phase fluctuation of the order parameter. Taking the two-local-spin-mediated interaction (TLSMI) proposed by Liu and Chen [Phys. Rev. B 58 (1998) 8812] as a Cooper pair potential, and the T-c formula, this paper explains five basic experimental facts in high-T-c cuprates. The aim of this paper is to show that TLSMI is a possible pairing mechanism of superconductivity in high-T-c cuprates. (C) 2000 Elsevier Science B.V.
