description: Thermal or chaotic light sources emit radiation characterized by a slightly enhanced probability of emitting photons in bunches, described by a zero-delay second-order correlation function $g^{(2)}(0) = 2$. Here we explore photon-coincidence counting statistics of thermal cavities in the ultrastrong coupling regime, where the atom-cavity coupling rate becomes comparable to the cavity resonance frequency. We find that, depending on the system temperature and coupling rate, thermal photons escaping the cavity can display very different statistical behaviors, characterised by second-order correlation functions approaching zero or greatly exceeding two.

description: We present a model for hybrid compact stars composed of a quark core and a hadronic mantle with an abrupt first order phase transition at the interface and in accordance with the latest astrophysical measurements of two 2 M_sun pulsars. We demonstrate the possibility of a disconnected mass-radius sequence (third family) of high-mass pulsars as a distinct feature due to a large jump $Δε$ in the energy density of the first order phase transition setting in at $ε_{\rm crit}\approx 500$ MeV/fm$^3$ and fulfilling $Δε/ε_{\rm crit} > 0.6$. We conclude that the measurement of so called \textit{twin} compact stars at high mass (~ 2 M_sun) would support the existence of a first order phase transition in symmetric matter at zero temperature entailing the existence of a critical end point (CEP) in the QCD phase diagram.

description: The hat section used by certain of the aircraft companies has been quite widely accepted as the most efficient compression carrying member when stiffened by a sheet.  However, due to the difficulty of inspection and corrosion control, which is particularly important in naval aircraft, the Consolidated Vultee Aircraft Corporation has for some time been using open angle and zee sections formed from dural sheet.  For this reason the members of the engineering staff of Consolidated Vultee became interested in the effect of lips on zee and angle sections such as are frequently used to stiffen panels occurring in the compression side of semi-monocoque structures subjected to bending loads.

This paper is an attempt to determine experimentally the optimum amount of lip for the sections under consideration.  Sufficient tests are made to locate the column curves for these sections, and from the curves the strengthening effect of the lip noted.

description: We study the decays of the lightest axial-vector and pseudovector mesons, interpreted as quark-antiquark states, into a vector and a pseudoscalar meson. We show that the quarkonium assignment delivers a good description of the decays and allows also to make further testable predictions. In the kaonic sector, the physical resonances $K_{1}(1270)$ and $K_{1}(1400)$ emerge as mixed objects of an axial vector state $K_{1,A}$ and a pseudovector state $K_{1,B}$. We determine the mixing angle as $\left\vert θ_{K}\right\vert=\left(33.6\pm4.3\right) ^{\circ}$, a value compatible with previous studies but with a smaller uncertainty. This result may be helpful for testing models beyond the Standard Model of particle physics in which decays into the kaonic resonances $K_{1}(1270)$ and $K_{1}(1400)$ are investigated.

Measurement of Direct-Photon Elliptic Flow in Pb-Pb Collisions at sqrt(NN) = 2.76 TeV

description: We present the first measurement of the direct-photon elliptic flow v_{2}^{γ,dir} in Pb-Pb collisions at sqrt(NN) = 2.76 TeV with data taken by the ALICE experiment at the LHC. The measurement provides evidence for a non-zero v_{2}^{γ,dir} for 1 < p_T < 3 GeV/c with a magnitude similar to the observed charged pion v_2. In order to explain the large inverse slope parameter T_eff of the low p_T direct-photon spectrum observed at LHC and RHIC, recent hydrodynamical descriptions of the direct-photon production include a substantial portion of thermal photons from the hot plasma phase. As a consequence of the early production time, v_{2}^{γ,dir} is expected to be small compared to hadrons. A large v_{2}^{γ,dir} might lend support for a significant direct-photon emission from late stages of the system evolution where hadron flow has developed.

Performance calculations of new propellant systems

Publisher: name: California Institute of Technology
Year: 1947
Subjects: Aeronautical Engineering
Aeronautics

description: The purpose of this thesis is to investigate the effect on performance
and chamber temperature of adding hydrogen to a propellant system. The systems
investigated are:

(1) RFNA-Aniline
(2) Nitromethane
(3) Anhydrous hydrazene-liquid oxygen

Since a systematic investigation of the performance parameters of the
RFNA-Aniline system over a wide range of mixture ratios has never been made,
it was decided to make these calculations, in addition to the investigations
stated above.

The results of the calculations can best be summarized by a study of the
figures at the end of the thesis.  A few generalizations can be made. The
effect of adding hydrogen in small quantities to a high temperature system
is to increase the performance considerably without too much change in the
chamber temperature. As more hydrogen is added, the percentage increase in performance.
If hydrogen is added in large quantities, both the performance curve
(effective exhaust velocity) and the chamber temperature curve flatten out.

The behavior discussed above is characteristic of hot propellant systems
such as RFNA-Aniline and anhydrous hydrazene. In a low temperature system,
such as nitromethane, the effect is quite different. The addition
of hydrogen in small quantities causes a rapid decrease in chamber temperature,
but the increase in performance is considerably less on a percentage basis.
As more hydrogen is added the changes in performance and chamber temperature
are almost linear.

description: The general problem of aerodynamics is the determination of the forces and moments imposed on a stationary body immersed in a moving fluid.  The problem is soluble if a mathematical calculation of the velocity distribution throughout the fluid can be made.  The application of certain restrictions facilitates the calculation.  Without great loss of usefulness we may restrict the motion to a steady, uniform, and rectilinear flow from infinity.  With considerable loss of usefulness but with tremendous simplification in calculation we may add the further restrictions that the fluid be non-viscous and incompressible.  Upon these assumptions the problem may be solved by utilizing two physical relationships, namely, the equations of motion and continuity.

description: В случае с Нарвой мы не наблюдаем радикального размежевания «дел купцов» и «дел земли» в административной деятельности ее фогтов, что было обусловлено, в первую очередь, важным военно-стратегическим и экономическим значением этого города, а также его более скромным, чем у Ревеля, статусом. Орден в лице фогта и направлявшего его деятельность ливонского магистра руководствовался, в первую очередь, военно-стратегическими целями, а город — торгово-экономическими, что временами приводило к разногласиям, однако серьезных конфликтов не случалось, поскольку основные действия орденской администрации были полезны горожанам, особенно в случаях усиления их позиций в их деловом и судебно-процессуальном общении с гражданами Ревеля.

description: We point out that the cosmological moduli problem is not necessarily resolved even if the modulus mass is heavier than O(10)TeV, contrary to the common wisdom. The point is that, in many scenarios where the lightest moduli fields are stabilized by supersymmetry breaking effects, those moduli fields tend to mainly decay into almost massless axions, whose abundance is tightly constrained by the recent Planck results. We study the moduli-induced axion problem in concrete examples, and discuss possible solutions. The problem and its solutions are widely applicable to decays of heavy scalar fields which dominate the energy density of the Universe, for instance, the reheating of the inflaton.

Growth Index after the Planck Results

Publisher: name: arXiv

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: The growth index $γ_L$ was proposed to investigate the possible deviation from the standard $Λ$CDM model and Einstein's gravity theory in a dynamical perspective. Recently, thanks to the measurement of the cosmic growth rate via the redshift-space distortion, one can understand the evolution of density contrast through $fσ_8(z)$, where $f(z)=d\ln δ/d \ln a$ is the growth rate of matter and $σ_8(z)$ is the rms amplitude of the density contrast $δ$ at the comoving $8h^{-1}$ Mpc scale. In this paper, we use the redshift space distortion data points to study the growth index on the bases of Einstein's gravity theory and a modified gravity theory under the assumption of $f=Ω_m(a)^{γ_L}$. The cosmic background evolution is fixed by the cosmic observations from the type Ia supernovae SNLS3, cosmic microwave background radiation data from {\it Planck} and baryon acoustic oscillations. Via the Markov Chain Monte Carlo method, we found the $γ_L$ values for Einstein's gravity with a cosmological constant, $w=constant$ dark energy and a modified gravity theory in the $1,2,3σ$ regions respectively: $0.675_{-0.0662-0.120-0.155}^{+0.0611+0.129+0.178}$, $0.745_{-0.0819-0.146-0.190}^{+0.0755+0.157+0.205}$ and $0.555_{-0.0167-0.0373-0.0516}^{+0.0193+0.0335+0.0436}$. In the Einstein's gravity theory, the values of growth index $γ_L$ show almost $2σ$ deviation from the theoretical prediction 6/11 for the $Λ$CDM model. However in the modified gravity framework, a deviation from the Einstein's relativity is not detected in $1σ$ region. That implies that the currently available cosmic observations don't expect an alternative modified gravity theory beyond the $Λ$CDM model under Einstein's gravity, but that the simple assumption of $f=Ω_m^{γ_L}$ should be improved.

description: We present results on structural and magnetic properties of highly crystalline alpha-Fe2O3 nanoparticles of average size ~200 nm, synthesized from a novel sol-gel method using metal alkoxide precursor. These particles are multi-domain, showing the weak ferromagnetic-antiferromagnetic (WF-AF) transition (i.e., the Morin transition) at T_M = 256(2) K. Mössbauer measurements revealed a jump in hyperfine parameters at T ~ T_M, which also displays thermal hysteresis upon cooling or heating the sample. The analysis of hyperfine parameters as a function of temperature allowed us to discard temperature gradients as well as the coexistence of WF/AF phases as possible origins of this hysteretic behaviour. Instead, the hysteresis can be qualitatively explained by the small size and high-crystallinity of the particles, which hinder the nucleation of the WF or AF phases yielding metastable states beyond TM.

Year: 2021

description: Despite the impressive accomplishments in the development of small molecule kinase inhibitors over the past 25 years, the majority of human kinases still lack high-quality inhibitors that can be used as chemical probes to investigate their biological function and pharmacology. Many members of the untargeted kinome are known to play a crucial role in the cell cycle and thus represent unexploited cancer drug targets. NIMA-related kinase 1 (Nek1) is one such example, which has lately gained attention for its widespread function in ciliogenesis, apoptosis, and the DNA-damage response and is involved in numerous cancers and several ciliopathies, and neurodegenerative diseases. This work reports the development of the first selective high-quality tool compounds for Nek1 inhibition using structure-guided medicinal chemistry methods. In the first step, two novel 7 azaindole scaffolds were derived from published structural data and reported kinome cross-screening analyses. Iterative steps of computer-assisted design, synthesis, and evaluation of structure-activity-relationships then led to the identification of seven lead compounds, and the top compound was further profiled for its in vivo efficacy, toxicity, and bioavailability in a self-established zebrafish polycystic kidney disease model. Administration of the top compound caused the quantifiable expansion of fluorescence-labeled proximal convoluted tubules, thus supporting the hypothesis that Nek1-inhibition causes cystic kidneys in zebrafish embryos. The methods used provide a blueprint for the fast and resource-efficient development of chemical probes for other dark kinases from widely available chemogenomic kinase data sets.

A study of the longitudinal low frequency (phugoid) motion of an airplane at supersonic and hypersonic speeds
Creators: name: Walter, Uso
Publisher: name: California Institute of Technology
Year: 1967
Subjects: Aeronautics

description: NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

The character of the longitudinal low frequency (phugoid) motion of a rigid airplane with controls fixed is investigated for the flight Mach number range from 1.25 to 8.0 using the physical and aerodynamic data of the North American X-15 research airplane.

The validity of the simplifying assumptions made in most low speed airplane stability investigations (symmetry of the airplane and of the air flow, small perturbations) is established for the problem under consideration.

The equations of longitudinal motion have been solved for the flight altitudes: sea level, 20,000 ft., 40,000 ft., and 60,000 ft.; and in, addition the roots of the simplified equations resulting from the phugoid approximation have been calculated for the same flight situations. It is found that the deviation of these approximate solutions from the solutions of the complete longitudinal equations is below 5 per cent throughout the considered range of flight conditions, and for most calculated points is less than 2 per cent. The phugoid roots are complex at 60,000 ft. altitude and real at sea level, with transition from one mode to the other at the intermediate flight altitudes. The real part of the roots is always negative, i. e., there is no divergence of the motion. Using the phugoid approximation, a criterion for the de-generation of the periodic phugoid mode into aperiodic modes is derived in form of a critical value of the lift to drag ratio [...].

In an appendix, the influence of an additional damping force (thrust control by the auto-pilot) on the character of the phugoid roots is shown.

description: We consider the problem of two heavy impurity particles embedded in a gas of weakly-interacting light mass bosonic particles in the condensed state. Using the Bogoliubov approach to describe the bosonic gas and the Born-Oppenheimer approximation for the three-body dynamics, we calculate the modification to the heavy-heavy two-body potential due to the presence of the condensate. For the case of resonant interaction between the light bosons and the impurities, we present (semi)-analytical results for the potential in the limit of a large condensate coherence length. In particular, we find a formula for the modification of the Efimov scaling factor due to the presence of a degenerate bosonic gas background.

description: The double-slit experiment strikingly demonstrates the wave-particle duality of quantum objects. In this famous experiment, particles pass one-by-one through a pair of slits and are detected on a distant screen. A distinct wave-like pattern emerges after many discrete particle impacts as if each particle is passing through both slits and interfering with itself. While the direct event-by-event buildup of this interference pattern has been observed for massive particles such as electrons, neutrons, atoms and molecules, it has not yet been measured for massless particles like photons. Here we present a temporally- and spatially-resolved measurement of the double-slit interference pattern using single photons. We send single photons through a birefringent double-slit apparatus and use a linear array of single-photon detectors to observe the developing interference pattern. The analysis of the buildup allows us to compare quantum mechanics and the corpuscular model, which aims to explain the mystery of single-particle interference. Finally, we send one photon from an entangled pair through our double-slit setup and show the dependence of the resulting interference pattern on the twin photon's measured state. Our results provide new insight into the dynamics of the buildup process in the double-slit experiment, and can be used as a valuable resource in quantum information applications.
An application of matrix methods to wing theory

Subjects: Aeronautics

description: The calculation of spanwise lift distribution of a wing by a new method proposed by Theodore von Karman and W. R. Sears* depends on knowledge of certain "characteristic values" (eigenvalues) and "characteristic functions" (eigenfunctions) of the wing planform. These functions are solutions of a homogeneous boundary-value problem of the third kind.

In the present paper the eigenvalues and the eigenfunctions, in series form, are calculated for a class of planforms by the method of successive multiplication of matrices.

The class of planforms considered is that of trapezoidal wings with rounded tips. The eigenvalues and eigenfunctions are calculated for taper ratios 1:1, 2:1, 3:1, and 4:1; they are independent of aspect ratio. It is found, that for intermediate taper ratios they can be determined with reasonable accuracy by graphical interpolation.

description: We theoretically study the current-driven domain wall motion in the presence of both the spin Hall effect and an extrinsic pinning potential. The spin Hall effect mainly affects the damping ratio of the domain wall precession in the pinning potential. When the pinning potential is not too strong, this results in a significant reduction of a threshold current density for the depinning of a domain wall with certain polarity. We also propose one way to distinguish the spin Hall effect induced spin-transfer torque from the one induced by the Rashba spin-orbit coupling experimentally.

description: The ongoing interest of researchers in bioderived polylactide (PLA) is due to the current tendency to replace petroleum-based plastics with polymers from renewable resources. Polylactide fits this trend because of its mechanical properties resembling those of some petroleum-based polymers commonly applied in daily life and because of its degradability. Added value is the excellent biocompatibility of PLA thanks to which it has found an application in biomedicine. This great interest in polylactide is reflected in the literature. Crosslinking of polylactide was also studied by many authors as an easy method of the improvement and the modification of its properties (thermal, mechanical, rheological, degradability) according to requirements of existing or possible applications. In the present review, the examples of polylactide and its copolymers crosslinking by chemical approaches described in the literature are presented. Thus, chemical methods including peroxide-induced radical crosslinking and crosslinking by coupling of functional PLA prepolymers via condensation/addition reactions are discussed. The results of PLA modification and examples of new, interesting materials obtained via different crosslinking methods are shown.

description: We report a study of the magnetoresistivity of high purity Sr$_3$Ru$_2$O$_7$, in the vicinity of its electronic nematic phase. By employing a triple-axis (9/1/1T) vector magnet, we were able to precisely tune both the magnitude and direction of the in-plane component of the magnetic field (H$_\parallel$). We report the dependence of the resistively determined anisotropy on H$_\parallel$ in the phase, as well as across the wider temperature-field region. Our measurements reveal a high-temperature anisotropy which mimics the behaviour of fluctuations from the underlying quantum critical point, and suggest the existence of a more complicated phase diagram than previously reported.

description: It is mostly unclear which personal predispositions are associated with knowledge about how to protect one’s privacy online and actually protecting it. More elaborate knowledge on this topic may help in the design process of user interfaces. Therefore, we investigated person characteristics underlying individual differences in online privacy literacy and behavior. N = 1,073 (n = 500 men) participants completed the Online Privacy Literacy Scale, an Online Privacy Behavior Scale, the Big Five Inventory, and a test assessing crystallized intelligence in an online survey. Online privacy literacy and behavior were significantly, moderately positively related. Both were significantly positively related to crystallized intelligence. Online privacy behavior was additionally significantly positively related to Openness. The results give insights into individual factors associated with knowledge about online privacy settings and related behaviors. In addition, results can help optimizing design of user interfaces/assistive technologies that support (certain) users to implement their data protection rights.

description: We discuss heat transport through a Josephson tunnel junction under various bias conditions. We first derive the formula for the cooling power of the junction valid for arbitrary time dependence of the Josephson phase. Combining it with the classical equation of motion for the phase, we find the time averaged cooling power as a function of bias current or bias voltage. We also find the noise of the heat current and, more generally, the full counting statistics of the heat transport through the junction. We separately consider the metastable superconducting branch of the current-voltage characteristics allowing quantum fluctuations of the phase in this case. This regime is experimentally attractive since the junction has low power dissipation, low impedance and therefore may be used as a sensitive detector.
Stability of trapped degenerate dipolar Bose and Fermi gases

description: Trapped degenerate dipolar Bose and Fermi gases of cylindrical symmetry with the polarization vector along the symmetry axis are only stable for the strength of dipolar interaction below a critical value. In the case of bosons, the stability of such a dipolar Bose-Einstein condensate (BEC) is investigated for different strengths of contact and dipolar interactions using variational approximation and numerical solution of a mean-field model. In the disk shape, with the polarization vector perpendicular to the plane of the disk, the atoms experience an overall dipolar repulsion and this fact should contribute to the stability. However, a complete numerical solution of the dynamics leads to the collapse of a strongly disk-shaped dipolar BEC due to the long-range anisotropic dipolar interaction. In the case of fermions, the stability of a trapped single-component degenerate dipolar Fermi gas is studied including the Hartree-Fock exchange and Brueckner-Goldstone correlation energies in the local density approximation valid for a large number of atoms. Estimates for the maximum allowed number of polar Bose and Fermi molecules in BEC and degenerate Fermi gas are given.

description: Sensitive monitoring of Plasmodium infective mosquitoes in low malaria transmission settings is of high priority for disease control. Early detection of insecticide resistance at low frequencies is also key for vector monitoring nowadays, when new insecticides are launched to control vector populations. An. gambiae mosquitoes with predetermined infection and resistance status were used to produce populations with various malaria infection rates and mutant allelic frequencies (MAFs) of target site insecticide resistance traits. Total RNA and gDNA were isolated and used in droplet Digital PCR (ddPCR) and Reverse Transcription (RT) ddPCR performed in the QX200 ddPCR System. We developed a novel ddPCR for detecting P. falciparum DNA in pooled mosquito head-thoraces with infective rate as low as 1.0%. A dissection-free RT-ddPCR assay for specific infective-stage detection was additionally developed and validated (accuracy = 100%) in mosquito pools with infective rates down to 1.0%. A novel ddPCR assay for insecticide resistant alleles, which was able to reliably quantify MAFs as low as 0.050% in pooled mosquito specimens, is also reported. We developed highly sensitive and efficient (RT-) ddPCR assays for contemporary operational needs that require monitoring of low malaria transmission and emerging insecticide resistance.

description: We show that it is possible to clone quantum states to arbitrary accuracy in the presence of a Deutschian closed timelike curve (D-CTC), with a fidelity converging to one in the limit as the dimension of the CTC system becomes large---thus resolving an open conjecture from [Brun et al., Physical Review Letters 102, 210402 (2009)]. This result follows from a D-CTC-assisted scheme for producing perfect clones of a quantum state prepared in a known eigenbasis, and the fact that one can reconstruct an approximation of a quantum state from empirical estimates of the probabilities of an informationally-complete measurement. Our results imply more generally that every continuous, but otherwise arbitrarily non-linear map from states to states can be implemented to arbitrary accuracy with D-CTCs. Furthermore, our results show that Deutsch's model for CTCs is in fact a classical model, in the sense that two arbitrary, distinct density operators are perfectly distinguishable (in the limit of a large CTC system); hence, in this model quantum mechanics becomes a classical theory in which each density operator is a distinct point in a classical phase space.

description: Photosystem II (PSII) and its associated light-harvesting complex II (LHCII) are highly concentrated in the stacked grana regions of photosynthetic thylakoid membranes. Within the membrane, PSII-LHCII supercomplexes can be arranged in disordered packings, ordered arrays, or mixtures thereof. The physical driving forces underlying array formation are unknown, complicating attempts to determine a possible functional role for arrays in regulating light harvesting or energy conversion efficiency. Here we introduce a coarse-grained model of protein interactions in coupled photosynthetic membranes, focusing on just two particle types that feature simple shapes and potential energies motivated by structural studies. Reporting on computer simulations of the model's equilibrium fluctuations, we demonstrate its success in reproducing diverse structural features observed in experiments, including extended PSII-LHCII arrays. Free energy calculations reveal that the appearance of arrays marks a phase transition from the disordered fluid state to a system-spanning crystal, which can easily be arrested by thermodynamic constraints or slow dynamics. The region of fluid-crystal coexistence is broad, encompassing much of the physiologically relevant parameter regime. Our results suggest that grana membranes lie at or near phase coexistence, conferring significant structural and functional flexibility to this densely packed membrane protein system.

Mean-speed measurements in two-dimensional, incompressible, fully-developed turbulent channel flow
Creators: name: Skinner, George Tolmie
Publisher: name: California Institute of Technology
Year: 1951
Subjects: Aeronautics

description: Mean velocity profiles were measured in the 5” x 60” wind channel of the turbulence laboratory at the GALCIT, by the use of a hot-wire anemometer.  The repeatability of results was established, and the accuracy of the instrumentation estimated.  Scatter of experimental results is a little, if any, beyond this limit, although some effects might be expected to arise from variations in atmospheric humidity, no account of this factor having been taken in the present work.  Also, slight unsteadiness in flow conditions will be responsible for some scatter.

Irregularities of a hot-wire in close proximity to a solid boundary at low speeds were observed, as have already been found by others.

That Kármán’s logarithmic law holds reasonably well over the main part of a fully developed turbulent flow was checked, the equation u/ut = 6.0 + 6.25 log10  yut/v  being obtained, and, as has been previously the case, the experimental points do not quite form one straight line in the region where viscosity effects are small.  The values of the constants for this law for the best over-all agreement were determined and compared with those obtained by others.

The range of Reynolds numbers used (based on half-width of channel) was from 20,000 to 60,000.
On the structure of laminar diffusion flames

Publisher: name: California Institute of Technology

Subjects: Aeronautics

description: The structure of laminar diffusion flames is analyzed in the limiting case of large, although finite, reaction rates.

It is shown that the the chemical reaction takes place only in a very thin region or "chemical boundary layer" where convection effects may be neglected. Then the temperature and mass fraction distributions within the reaction zone are obtained analytically.

The flame position, rates of fuel consumption, and temperature and concentration distributions outside the reaction zone may be obtained by using the assumption of infinite reaction rates.

For large Reynolds numbers mixing and combustion take place in boundary layers and free mixing layers. And again analytical solutions are obtained for the temperature and mass fraction distributions outside of the reaction zone.
