description: The optical spectrum of samarium atoms trapped in matrices of argon and krypton at 4.2°K was examined. A simple basis for interpretation of the results is presented, in which the matrix perturbation is applied to the free atom in some quantum state of total angular momentum J.

The spectra can be correlated with the published data for SmI, but the complexity of the results, particularly in argon, make a detailed interpretation difficult. Some exceptionally sharp triplets with small splittings are considered to be derived from levels of the excited 4f^55d6s^2 configuration, none of which has previously been identified. Fluorescence was observed, corresponding to transitions from an excited state to the ^7F_1 and ^7F_2 levels of the ground state.

description: The AMS experiment onboard the International Space Station has recently provided cosmic ray electron and positron data with unprecedented precision in the range from 0.5 to 350 GeV. The observed rise in the positron fraction at energies above 10 GeV remains unexplained, with proposed solutions ranging from local pulsars to TeV-scale dark matter. Here, we make use of this high quality data to place stringent limits on dark matter with masses below ~300 GeV, annihilating or decaying to leptonic final states, essentially independent of the origin of this rise. We significantly improve on existing constraints, in some cases by up to two orders of magnitude.

description: GNOSIS is a prototype astrophotonic instrument that utilizes OH suppression fibres consisting of fibre Bragg gratings and photonic lanterns to suppress the 103 brightest atmospheric emission doublets between 1.47-1.7 microns. GNOSIS was commissioned at the 3.9-meter Anglo-Australian Telescope with the IRIS2 spectrograph to demonstrate the potential of OH suppression fibres, but may be potentially used with any telescope and spectrograph combination. Unlike previous atmospheric suppression techniques GNOSIS suppresses the lines before dispersion and in a manner that depends purely on wavelength. We present the instrument design and report the results of laboratory and on-sky tests from commissioning. While these tests demonstrated high throughput and excellent suppression of the skylines by the OH suppression fibres, surprisingly GNOSIS produced no significant reduction in the interline background and the sensitivity of GNOSIS and IRIS2 is about the same as IRIS2. It is unclear whether the lack of reduction in the interline background is due to physical sources or systematic errors as the observations are detector noise-dominated. OH suppression fibres could potentially impact ground-based astronomy at the level of adaptive optics or greater. However, until a clear reduction in the interline background and the corresponding increasing in sensitivity is demonstrated optimized OH suppression fibres paired with a fibre-fed spectrograph will at least provide a real benefits at low resolving powers.

description: This paper aims at advancing the field of electro-sensing. It exhibits the physical mechanism underlying shape perception for weakly electric fish. These fish orient themselves at night in complete darkness by employing their active electrolocation system. They generate a stable, high-frequency, weak electric field and perceive the transdermal potential modulations caused by a nearby target with different admittivity than the surrounding water. In this paper, we explain how weakly electric fish might identify and classify a target, knowing by advance that the latter belongs to a certain collection of shapes. Our model of the weakly electric fish relies on differential imaging, i.e., by forming an image from the perturbations of the field due to targets, and physics-based classification. The electric fish would first locate the target using a specific location search algorithm. Then it could extract, from the perturbations of the electric field, generalized (or high-order) polarization tensors of the target. Computing, from the extracted features, invariants under rigid motions and scaling yields shape descriptors. The weakly electric fish might classify a target by comparing its invariants with those of a set of learned shapes. On the other hand, when measurements are taken at multiple frequencies, the fish might exploit the shifts and use the spectral content of the generalized polarization tensors to dramatically improve the stability with respect to measurement noise of the classification procedure in electro-sensing. Surprisingly, it turns out that the first-order polarization tensor at multiple frequencies could be enough for the purpose of classification. A procedure to eliminate the background field in the case where the permittivity of the surrounding medium can be neglected, and hence improve further the stability of the classification process, is also discussed.

The effect of imperfections on the buckling of cylindrical shells
Creators: name: Imbert, Jean-Francois
Publisher: name: California Institute of Technology
Year: 1971
Subjects: Aeronautics

description: A theoretical investigation of the effect of general imperfections on the buckling of a cylindrical shell under axial compression was carried out. A limit point analysis was performed to determine the buckling loads using a simplified imperfection and displacement model consisting of one axisymmetric and two asymmetric components with the same circumferential wave number.

The wave number dependence of imperfections for a class of shells obtained by the same manufacturing processes was characterized by using an imperfection model to fit the experimental imperfection coefficients available. Buckling load calculations were performed using both experimental and fitted data as imperfection coefficients.

For the experimental data available the three-mode solution was found to have only a small additional effect with respect to the two-mode solution. In addition, by extrapolating imperfection coefficients for high wave numbers by means of the imperfection model, it was found that a strong interaction effect would exist between a low wave number axisymmetric mode and two classical asymmetric modes.

description: Chitin, which is the polymer of N-acetylglucosamine (GlcNAc) linked by β1,4 glycoside bonds, has been reported as a soil amendment to mitigate plant soil diseases, increasing the population of chitin-degrading bacteria, and chitinolytic enzymatic activity in the soil. In some chitin-degrading bacteria, whose chitinolytic systems have been intensively studied, the chitin degradation product N,Nʹ-diacetylchitobiose {(GlcNAc)2} induces expression of genes for chitinases whereas GlcNAc does not. To evaluate the effects of these mono- and disaccharides on the population and activity of chitinolytic bacteria in soil, we investigated the chitinolytic enzyme activity and bacterial community structure in an incubated upland soil supplemented with GlcNAc or (GlcNAc)2. The added GlcNAc and (GlcNAc)2 (2 mg g−1) were consumed within 1 d when incubated at 25°C. Chitinase activity was induced by (GlcNAc)2 and chitin after 1-d and 7-d incubation, respectively, but not by GlcNAc. N-acetylglucosaminidase (GlcNAcase) activity was induced by GlcNAc but was lower than those by (GlcNAc)2 and chitin. Amplicon sequencing analysis targeting 16S rRNA genes demonstrated that both GlcNAc and (GlcNAc)2 significantly increased the rate of the order Bacillales, but the compositions of Bacillales differed from each other: the family Planococcaceae significantly increased in either GlcNAc- or (GlcNAc)2-added soil, but the genera Bacillus and Paenibacillus were increased mainly by GlcNAc and (GlcNAc)2, respectively. The family Streptomycetaceae of the order Actinomycetales was significantly increased by (GlcNAc)2 and chitin, but GlcNAc did not. Thus, GlcNAc and (GlcNAc)2, which were promptly consumed in the incubated soil, indicated partly similar but distinctive effects on chitinolytic enzyme activity and bacterial communities. Both aminosugars increased GlcNAcase activity and the population size of Planococcaceae. GlcNAc increased Bacillus. Chitinase activity and the populations of Paenibacillus and Streptomycetaceae, a number of strains of which are known as potent chitin-degraders, were increased by (GlcNAc)2, but not by GlcNAc.

description: We construct a number($n$)-resolved master equation (ME) approach under self-consistent Born approximation (SCBA) for noise spectrum calculation. The formulation is essentially non-Markovian and incorporates properly the interlay of the multi-tunneling processes and many-body correlations. We apply this approach to the challenging nonequilibrium Kondo system and predict a profound nonequilibrium Kondo signature in the shot noise spectrum. The proposed $n$-SCBA-ME scheme goes completely beyond the scope of the Born-Markovian master equation approach, in the sense of being applicable to the shot noise of transport under small bias voltage, in non-Markovian regime, and with strong Coulomb correlations as favorably demonstrated in the nonequilibrium Kondo system.

description: This thesis marks the culmination of four years’ work, as part of my PhD study in composition. The portfolio consists of ten pieces, lasting in total approximately 2 hours and 10 minutes, and a commentary comprising an analysis of each of the works. The main emphasis has been on the development of an individual style, informed by the exploration of twentieth and twenty-first century compositional techniques, instrumental timbres, stylistic genres, forms, scale derivations and the wider aesthetic of contemporary music. The portfolio includes works for solo instruments, ensemble and orchestra. One of the main areas of research has been to devise combinatorial scales, based on modality, whole-tone scales and pentatony, based on my knowledge and experience of a range of musical traditions and genres, both western and eastern, thereby deriving new melodic and harmonic resources. Each piece in the portfolio was written with one or more different concepts in mind and consists of either single- or multi-movement formats.

Self-excited torsional oscillations of an airfoil

description: This thesis is a report on one phase of a program on the self-excited oscillations of an airfoil. This program was sponsored by the National Advisory Committee for Aeronautics at the California Institute of Technology. This thesis covers the torsional oscillations of an elastically suspended airfoil.

The experimental work consisted of measurements of the amplitude of torsional oscillations of a wing elastically suspended in the airstream of a wind tunnel so as to be capable of torsional oscillations only. The results show that torsional oscillations occur at all velocities above a critical velocity and increase in amplitude with velocity without reaching any apparent limit.

Glauert's theory of the forces on an oscillating airfoil do not agree with the experimental results obtained. This theory indicates that oscillations below the stall will not occur for the values of V/nb studied here, whereas the experiments indicate that oscillations do exist.

description: Before being settled on farms, land redistribution must be supported with the essential resources required for sustained farming production, and its beneficiaries must be capacitated. Then, to ensure that farming productions are sustainable, they must be monitored and evaluated. Then, on a larger scale, land reform beneficiaries' livelihoods must be improved. Based on all of the aforementioned criteria, research was begun to build a model that will ensure that land acquisition is done in a sustainable manner, thereby improving beneficiaries' livelihoods.
Width bifurcation and dynamical phase transitions in open quantum systems

Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The states of an open quantum system are coupled via the environment of scattering wavefunctions. The complex coupling coefficients $ω$ between system and environment arise from the principal value integral and the residuum. At high level density where the resonance states overlap, the dynamics of the system is determined by exceptional points. At these points, the eigenvalues of two states are equal and the corresponding eigenfunctions are linearly dependent. It is shown in the present paper that Im$(ω)$ and Re$(ω)$ influence the system properties differently in the surrounding of exceptional points. Controlling the system by a parameter, the eigenvalues avoid crossing in energy near an exceptional point under the influence of Re$(ω)$ in a similar manner as it is well known from discrete states. Im$(ω)$ however leads to width bifurcation and finally (when the system is coupled to one channel, i.e. to a common continuum of scattering wavefunctions), to a splitting of the system into two parts with different characteristic time scales. Physically, the system is stabilized by this splitting since the lifetimes of most ($N-1$) states are longer than before while that of only one state is shorter. In the cross section the short-lived state appears as a background term in high-resolution experiments. The wavefunctions of the long-lived states are mixed in those of the original ones in a comparably large parameter range. Numerical results for the eigenvalues and eigenfunctions are shown for $N=2, ~4$ and 10 states coupled mostly to 1 channel.

Hydrogen Bonding in Alcohols
Creators: name: Rosser, Willis Andrew, Jr.
Publisher: name: California Institute of Technology
Year: 1952
Subjects: Chemistry

description: It is usually assumed in optical absorption work
that the natural stretching frequency of the hydroxyl
group in an alcohol is appreciably changed by hydrogen
bonding. A survey of work relating to hydrogen bonding
in alcohols favors this assumption. Moreover, it appears
that the deviation of alcohols in solvents such as carbon
tetrachloride from Henry's law is primarily due to
hydrogen bonding polymerization, the extent of such
deviation being the same for the lower aliphatic alcohols
and phenol.

Optical transmission measurements on dilute solutions
of methyl alcohol and of ethyl alcohol in carbon
tetrachloride were used to determine for these alcohols the
dimerization constants associated with the reaction.

2 ROH → (ROH)2

These constants in turn were used in support of the
contention that the polymerization constants associated with
the reactions

(ROH)g-1 + ROH → (ROH)g

are not independent of g as has been assumed on occasion.

The viscosity of solutions of alcohols in carbon
tetrachloride is briefly discussed in a semi-quantitative
manner.

description: Sorghum is important for its grain as food, animal feed, seeds and brewing local bear. Its stalks are used for shelter, animal feed and at times as source of sugar. This study was performed at Damazin Research Station, Damazin, (Latitude 11°47’34N, longitude 34°21’55 E) and approximately 343.01 meters above sea level (MSL) for two consecutive seasons of 2006/07 and 2007/08. There were three different types of seed beds used. namely, flat (control 1); normal ridged and tied ridged in a Striga infested field trial. The aim of this study to test for the incidence of witch weed (Striga spp.) and performance of sorghum under the different treatments. The procedures were carried out: two rates of urea fertilizers applied at 103.5 and 207.0 kg/ha; four leguminous plants namely, Bambara nuts, (Vigna subterranea L. Verdc.; Groundnuts, (Arachis hypogoea L.); Clitoria, (Clitoria ternatea); and Desmodium spp.) were intercropped with sorghum, Sorghum bicolor L. Moench (cv. Wad Ahmed) and a sole sorghum without any treatment (control 2) were compared for their effect on Striga population at 8 and 12 weeks after sorghum emergence (WASE); Striga dry weight at harvest; sorghum height and sorghum grain and straw yield. The results showed that standard ridged seedbeds effectively reduced Striga population and dry weight. Clitoria spp., among the legumes intercropped with sorghum, reduced sorghum height significantly, and the application urea fertilizers regardless of the rates used, increased sorghum grain yield as well as Striga population.

description: Metastasis is defined as the phenomenon of invasion and migration of cancer cells away from the original tumor to nearby tissues and other organs. Cancer metastasis is a complicated process and is the most harmful feature of cancer. Breast cancer is the most prevalent malignancy of the world and accounts for majority of cancer-associated deaths among women worldwide. In breast cancer metastasis, the cells separate from the original breast tumor and travel to remote organs such as the brain, liver, lungs, and bones via blood vessels or lymph nodes. Moreover, the preferred metastatic location of the disseminated breast cancer cells depends on their specific clinical subtypes. 10%-15% of the total number of patients affected by breast cancer develop the aggressive form of the disease causing the tumor cells to migrate to distant organs within three years of developing the primary tumor. When compared to the primary tumor, metastatic breast cancer is quite diverse in characteristics making it tedious to assess the risk factors responsible for promoting metastasis and discover an efficient and effective treatment approach. However, the formation of micrometastases at remote sites after ten years of initial diagnosis is quite natural. Therefore, the need to understand the basics of the metastasis process of breast cancer arises. In this review, a narrative description of the cellular and molecular mechanisms of breast cancer metastasis along with the emerging options of different therapeutic measures is provided.

description: An ideal source of entangled photon pairs combines the perfect symmetry of an atom with the convenient electrical trigger of light sources based on semiconductor quantum dots. We create a naturally symmetric quantum dot cascade that emits highly entangled photon pairs on demand. Our source consists of strain-free GaAs dots self-assembled on a triangular symmetric (111)A surface. The emitted photons strongly violate Bell's inequality and reveal a fidelity to the Bell state as high as 86 (+-2) % without postselection. This result is an important step towards scalable quantum-communication applications with efficient sources.

Geology of the upper Tick Canyon area, Los Angeles County, California

subject: FOS: Earth and related environmental sciences

description: The upper Tick Canyon area, approximately seven square
miles in extent, lies between Agua Dulce Canyon and Mint
Canyon in the easternmost pelt of the Ventura Basin in
southern California. This area was mapped in detail on a
scale of 1000 feet to one inch and the stratigrephic and
structural relationships of the exposed rocks were established.

The oldest rocks in the area are of highly metamorphosed
metasedimentary and metavolcanic types, which are intruded
by igneous bodies of presumed pre-Cretaceous age. This crystalline complex is in fault contact with the rocks of the Vasquez series, the oldest unit in a thick section of Tertiary sedimentary and volcanic rocks.

The Vasquez series is perhaps Oligocene in age and was
deposited under nonmarine conditions in an elongate trough of fault-block origin. The rocks are mainly fine-to coarse-
grained elastic sediments. Interlayered with them are
basaltic and andesitic flows and shallow intrusive masses,
that form with the sediments a total section of about 4500
feet. This section thickens rapidly east of the area mapped.

Overlying the Vasquez strata with a distinct angular unconformity is a series of conglomerates and siltstones of
the late Lower Miocene Tick Canyon formation. This unit is
approximately 900 feet thick, but thins rapidly to the west
within the area under consideration. The Upper Miocene Mint
Canyon formation, which also consists of nonmarine elastic
sedimentary rocks overlies the Tick Canyon formation throughout the area. These two formations probably are separated by an unconformity, along which there may be local angular discordance of a few degrees.

Almost flat-lying, Pleistocene stream deposits occur
throughout the area at an elevation of several hundred feet
above the present, newly alluviated valley bottoms.

Some strike-slip faulting with northeasterly trend took
place after Mint Canyon time, perhaps during the Pliocene
epoch. This may be related to the San Andreas fault, which
lies ten miles to the northeast.

All folds and faults that involve the sedimentary beds
probably can be related to adjustments taking place in the
underlying crystalline rocks. The forces causing these adjustments probably were active throughout much of Tertiary
and Quaternary time, and activities do not appear to have
ceased as yet.

description: On the basis of the percolation picture from the hadronic phase with hyperons to the quark phase with strangeness, we construct a new equation of state (EOS) with the pressure interpolated as a function of the baryon density. The maximum mass of neutron stars can exceed $2M_{\odot}$ if the following two conditions are satisfied; (i) the crossover from the hadronic matter to the quark matter takes place at around three times the normal nuclear matter density, and (ii) the quark matter is strongly interacting in the crossover region and has stiff equation of state. This is in contrast to the conventional approach assuming the first order phase transition in which the EOS becomes always soft due to the presence of the quark matter at high density. Although the choice of the hadronic EOS does not affect the above conclusion on the maximum mass, the three-body force among nucleons and hyperons plays an essential role for the onset of the hyperon mixing and the cooling of neutron stars.

description: We consider an interferometer powered by laser light (a coherent state) into one input port and ask the following question: what is the best state to inject into the second input port, given a constraint on the mean number of photons this state can carry, in order to optimize the interferometer's phase sensitivity? This question is the practical question for high-sensitivity interferometry. We answer the question by considering the quantum Cram{é}r-Rao bound for such a setup. The answer is squeezed vacuum.

description: Bertrand space-times (BSTs) are static, spherically symmetric solutions of Einstein's equations, that admit stable, closed orbits. Starting from the fact that to a good approximation, stars in the disc or halo regions of typical galaxies move in such orbits, we propose that, under certain physical assumptions, the dark matter distribution of some low surface brightness (LSB) galaxies can seed a particular class of BSTs. In the Newtonian limit, it is shown that for flat rotation curves, our proposal leads to an analytic prediction of the NFW dark matter profile. We further show that the dark matter distribution that seeds the BST, is described by a two-fluid anisotropic model, and present its analytic solution. A new solution of the Einstein's equations, with an internal BST and an external Schwarzschild metric, is also constructed.

description: Online discussion moderators must make ad-hoc decisions about whether the contributions of discussion participants are appropriate or should be removed to maintain civility. Existing research on offensive language and the resulting tools cover only one aspect among many involved in such decisions. The question of what is considered appropriate in a controversial discussion has not yet been systematically addressed. In this paper, we operationalize appropriate language in argumentation for the first time. In particular, we model appropriateness through the absence of flaws, grounded in research on argument quality assessment, especially in aspects from rhetoric. From these, we derive a new taxonomy of 14 dimensions that determine inappropriate language in online discussions. Building on three argument quality corpora, we then create a corpus of 2191 arguments annotated for the 14 dimensions. Empirical analyses support that the taxonomy covers the concept of appropriateness comprehensively, showing several plausible correlations with argument quality dimensions. Moreover, results of baseline approaches to assessing appropriateness suggest that all dimensions can be modeled computationally on the corpus.

description: Optimizing the phrasing of argumentative text is crucial in higher education and professional development. However, assessing whether and how the different claims in a text should be revised is a hard task, especially for novice writers. In this work, we explore the main challenges to identifying argumentative claims in need of specific revisions. By learning from collaborative editing behaviors in online debates, we seek to capture implicit revision patterns in order to develop approaches aimed at guiding writers in how to further improve their arguments. We systematically compare the ability of common word embedding models to capture the differences between different versions of the same text, and we analyze their impact on various types of writing issues. To deal with the noisy nature of revision-based corpora, we propose a new sampling strategy based on revision distance. Opposed to approaches from prior work, such sampling can be done without employing additional annotations and judgments. Moreover, we provide evidence that using contextual information and domain knowledge can further improve prediction results. How useful a certain type of context is, depends on the issue the claim is suffering from, though.

description: The identifications of transverse boost and rotation operators in light front theory done in Phys. Rev. Lett. {109}, 152005 (2012) is incorrect. The simple parton interpretation claimed is, in fact, for the transverse boost operator. Manifestation of Lorentz symmetry as claimed in the context of their calculation involving transverse Pauli-Lubanski polarization vector is unsupported.
