Modified Gelman Sampler obtains representative sample of microorganism population. Proposed Sample Collection Module is based on direct inoculation of selected solid growth media encased in a cartridge at all times except during inoculation. Cartridge can be handled with no danger of contamination to sample or operator
Inversion tectonics during continetal rifting : The Turkana Cenozoic rifted zone, northern Kenya
International audienceRemote sensing data and revised seismic reflection profiles provide new insights about the origin of inverted deformation within Miocene-Recent basins of the Turkana rift (northern Kenya) in the eastern branch of the East African rift system. Contractional structures are dominated by weakly inverted sets of fault blocks within <3.7 Myr old synrift series. Most of reverse extensional faults involve components of oblique-slip, whereas associated hanging wall folds are characterized by large wavelength upright folding. The area of basin inversion is restricted to a 40 Ă 100 km elongated zone overlying a first-order N140°E trending fault zone in the basement, referred to as the N'Doto transverse fault zone (NTFZ). In the proposed kinematic model, inversion tectonics is assigned to permutation of principal stress axes (Ï1/Ï2) in addition to the clockwise rotation of extension (from nearly N90°E to N130°E) during Pliocene. The transition from pure extension (Miocene) to a wrench faulting regime (Pliocene) first results in the development of T-type fault networks within a dextrally reactivated shear zone (NTFZ). Inversion tectonics occurred later (<3.7 Ma) in response to a still rotated (~20°) shortening axis (Ï1) oriented N40°E that caused the oblique compression of earlier (NS to N20°E) extensional structures within the NTFZ. The origin of basin inversion and strain concentration in the Turkana rift is thus directly linked to a crustal weakness zone, transverse to the rift axis, and involving steep prerift anisotropies
Applying the expanding photosphere and standardized candle methods to Type II-Plateau supernovae at cosmologically significant redshifts: the distance to SN 2013eq
Based on optical imaging and spectroscopy of the Type II-Plateau SN 2013eq,
we present a comparative study of commonly used distance determination methods
based on Type II supernovae. The occurrence of SN 2013eq in the Hubble flow (z
= 0.041 +/- 0.001) prompted us to investigate the implications of the
difference between "angular" and "luminosity" distances within the framework of
the expanding photosphere method (EPM) that relies upon a relation between flux
and angular size to yield a distance. Following a re-derivation of the basic
equations of the EPM for SNe at non-negligible redshifts, we conclude that the
EPM results in an angular distance. The observed flux should be converted into
the SN rest frame and the angular size, theta, has to be corrected by a factor
of (1+z)^2. Alternatively, the EPM angular distance can be converted to a
luminosity distance by implementing a modification of the angular size. For SN
2013eq, we find EPM luminosity distances of D_L = 151 +/- 18 Mpc and D_L = 164
+/- 20 Mpc by making use of different sets of dilution factors taken from the
literature. Application of the standardized candle method for Type II-P SNe
results in an independent luminosity distance estimate (D_L = 168 +/- 16 Mpc)
that is consistent with the EPM estimate.Comment: 12 pages, 4 figures, accepted by A&
NP-hardness of decoding quantum error-correction codes
Though the theory of quantum error correction is intimately related to the
classical coding theory, in particular, one can construct quantum error
correction codes (QECCs) from classical codes with the dual containing
property, this does not necessarily imply that the computational complexity of
decoding QECCs is the same as their classical counterparts. Instead, decoding
QECCs can be very much different from decoding classical codes due to the
degeneracy property. Intuitively, one expect degeneracy would simplify the
decoding since two different errors might not and need not be distinguished in
order to correct them. However, we show that general quantum decoding problem
is NP-hard regardless of the quantum codes being degenerate or non-degenerate.
This finding implies that no considerably fast decoding algorithm exists for
the general quantum decoding problems, and suggests the existence of a quantum
cryptosystem based on the hardness of decoding QECCs.Comment: 5 pages, no figure. Final version for publicatio
The Indianapolis Foundation Library Partners
In 1989 an anonymous bequest of nearly 25 million and producing approximately 16 million in grants to Marion County libraries. This resource in turn fostered a
collaborative environment among the libraries and librarians in Marion County that is also unique. In this article we describe the history of The Indianapolis
Foundation Library Partners, its current programs, and its growth over the years
Moxalactam Therapy for Obstetric and Gynecologic Infections
Moxalactam, a new cephalosporin antibiotic with a broad spectrum of activity, was evaluated for safety and therapeutic efficacy in the treatment of genital tract infections in women. Fifty-three patients with postpartum endometritis or acute or chronic pelvic inflammatory disease were treated with 2 g of moxalactam iv every 8 hr, usually for five days or longer. Appropriate cultures of peripheral blood, endometrium, cul-de-sac aspirates, urine, wound, and endocervix (only for Neisseria gonorrhoeae) were performed. Overall, 90.6% (48 of 53) of the patients were successfully treated with moxalactam - 86.2% (25 of 29) and 95.8% (23 of 24) of the patients with endometritis and pelvic inflammatory disease, respectively. Therapy failed in one of five bacteremic patients with endometritis. Of all the bacteria isolated from appropriate culture sites, 58% (224 of 383) were anaerobes, with anaerobic gram-negative rods - particularly Bacteroides bivius-and gram-positive cocci being predominant. Of 206 anaerobic strains tested with moxalactam by agar dilution techniques, 82% (169 of 206) were susceptible (minimal inhibitory concentration [MIC], ⩜8 Όg/ml), 11.6% (24 of 206) were moderately susceptible (MIC, 16-32 Όg/ml), and 6.3% (13 of 206) were resistant (MIC, ⩟64 Όg/ml). Among the aerobic isolates, enterococci were uniformly resistant. Thus, moxalactam performed well as a single agent in this open clinical trail for women with infections of the genital trac
Diagnostic accuracy of Doppler ultrasound technique of the penile arteries in correlation to selective arteriography
In 63% of 265 patients with erectile dysfunction a relevant arterial inflow disturbance was found by Doppler ultrasound examination. Correlation between Doppler and arteriography in 58 patients showed an accuracy of 95% in detecting penile arteries and an accuracy of 91% in discovering a pathological arterial pattern (arterial anomaly or arteriosclerotic obstruction). In 15 patients the arterial inflow was measured additionally by Doppler ultrasound technique after intracavernosal injection of vasoactive drugs (IIVD) (7.5 mg papaverine and 0.25 mg phentolamine). This technique proved to be more reliable than in the flaccid state and markedly facilitated localization and assessment of pathological changes of the cavernosal arteries
