description: Galaxies with the mass of the Milky Way dominate the stellar mass density of the Universe but it is uncertain how and when they were assembled. Here we study progenitors of these galaxies out to z=2.5, using data from the 3D-HST and CANDELS Treasury surveys. We find that galaxies with present-day stellar masses of log(M)~10.7 built ~90% of their stellar mass since z=2.5, with most of the star formation occurring before z=1. In marked contrast to the assembly history of massive elliptical galaxies, mass growth is not limited to large radii: the mass in the central 2 kpc of the galaxies increased by a factor of 3.2+-0.8 between z=2.5 and z=1. We therefore rule out simple models in which bulges were fully assembled at high redshift and disks gradually formed around them. Instead, bulges (and black holes) likely formed in lockstep with disks, through bar instabilities, migration, or other processes. We find that after z=1 the growth in the central regions gradually stopped and the disk continued to build, consistent with recent studies of the gas distributions in z~1 galaxies and the properties of many spiral galaxies today.

Creation of wormholes during the cosmological bounce

description: In this work we demonstrate that wormholes can in principle be naturally created during the cosmological bounce without the need for the exotic matter or any kind of additional modifications of the gravitational sector, apart from the one enabling the cosmological bounce. This result is general and does not depend on the details of the modifications of gravitational equations needed to support the bounce. To study the possible existence of wormholes around the cosmological bounce we introduce general modifications of Einstein's field equations need to support the bouncing solutions. In this regime we show that it is possible to construct a cosmological wormhole solution supported by matter, radiation and vacuum energy, satisfying the Weak Energy Condition (WEC), which asymptotically approaches the Friedmann-Lemaître-Robertson-Walker (FLRW) metric. However, at a specific cosmological time, which depends on the parameters of the bouncing cosmological model, the WEC describing the matter needed to support such wormholes is spontaneously violated. This means that such wormholes could potentially exist in large numbers during some period around the bounce, significantly changing the causal structure of space-time, and then vanish afterwards.

Preparation and characterization by streaming birefringence of sodium desoxyribonucleate
Creators: name: Hershman, Jerome Marshall
Publisher: name: California Institute of Technology

Subjects: Chemistry

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

Three preparations of the sodium salt of desoxyribonucleic acid were isolated from calf thymus by a method expected to give minimal or no depolymerization. In addition, preparations were made from calf spleen and bull testis tissues.

Streaming birefringence measurements indicate that the distributions of molecular length are identical in the calf thymus preparations. The apparent molecular lengths range from 7,500  to 11,500[...]. The sodium desoxyribonucleate from testis appeared to be significantly shorter; that from spleen was intermediate between thymus and testis. The distributions of molecular length of two calf thymus preparations isolated by N. Simmons were compared with those prepared here.

Several explanations are put forth to explain the polydispersity and discrepancies between preparations.
Techniques in Magnetic Resonance Imaging and the Applications of Diffusion Based Imaging
Creators: name: Bacon, James
Publisher: name: Zenodo
Year: 2023

description: Magnetic Resonance Imaging (MRI) has established itself as an essential tool in clinical medicine for both diagnosis and monitoring of disease and injury. It provides two major advantages over other imaging techniques including x-ray and CT; the first is safety due to the lack of ionising radiation, the second is the enhanced soft tissue contrast as images can be weighted based on multiple MRI parameters which vary between different tissue. This review will examine the physics used to create these images. This includes the creation and detection of the magnetic resonance signal, the spatial locating of the signal to form an image and the pulse sequences which are used to enhance the image contrast for diagnosis. A large amount of the imaging is based upon the detection of proton density found within water in the body. The review will also go on to explore the techniques of Diffusion Weighted Imaging and Diffusion Tensor Imaging based upon the diffusion, or lack of diffusion, of this water. This includes their applications to the diagnosis of ischaemic stroke and pancreatic lesions. Improvements to diffusion-based imaging are also considered in the context of the Human Connectome Project which uses tractography to map out the structural connectivity of the brain.

description: In the absence of spectra, fitting template model spectra to observed photometric fluxes, known as Spectral Energy Distribution (SED) fitting, has become the workhorse for identifying high-z galaxies. In this paper, we present an analysis of the most recent and possibly most distant galaxies discovered in the Hubble Ultra Deep Field using a more robust method of redshift estimation based on Markov Chain Monte Carlo fitting (MCMC), rather than relying on the redshift of "best fit" models obtained using common chi^2 minimization techniques. The advantage of MCMC fitting is the ability to accurately estimate the probability density function of the redshift, as well as any other input model parameters, allowing us to derive accurate credible intervals by properly marginalizing over all other input model parameters. We apply our method to 13 recently identified sources and show that, despite claims based on chi^2 minimization, none of these sources can be securely ruled out as low redshift interlopers given the low signal-to-noise of currently available observations. We estimate that there is an average probability of 21% that these sources are low redshift interlopers.

An experimental investigation of ignition and falme stabilization in a turbulent mixing zone
Creators: name: Becker, Jack L.
Publisher: name: California Institute of Technology
Year: 1952
Subjects: Aeronautics

description: The present investigation constituted the first part of an attempt to isolate the essentials of flame stabilization behind a bluff body. It is thought by many that such a flame is initiated and stabilized by heat transfer, the diffusion of active chemical species, and the chemistry of the combustible mixture involved.

The ignition of a fresh combustible mixture by a hot stream of gas provides possibility for detailed study of flame stabilization because of heat transfer.

Results indicate that the method followed herein to produce ignition resulted in the formation of two distinct types of flames. One flame seemed to be affected primarily by temperature, the other was affected by temperature, stream velocity and fuel-air ratio.

The work was carried on as part of a study of flame stabilization being conducted at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California.

Edge-Ferromagnetism from Majorana Flat-Bands: Application to Split Tunneling-Conductance Peaks in the High-Tc Cuprates

description: In mean-field descriptions of nodal d-wave superconductors, generic edges exhibit dispersionless Majorana fermion bands at zero-energy. These states give rise to an extensive ground-state degeneracy, and are protected by time-reversal (TR) symmetry. We argue that the infinite density of states of these flat-bands make them inherently unstable to interactions, and show that repulsive interactions lead to edge FM which splits the flat bands. This edge FM offers an explanation for the observation of splitting of zero-bias peaks in edge tunneling in High-Tc cuprate superconductors. We argue that this mechanism for splitting is more likely than previously proposed scenarios, and describe its experimental consequences.

Spinning dark matter halos promote bar formation

description: Stellar bars are the most common non-axisymmetric structures in galaxies and their impact on the evolution of disc galaxies at all cosmological times can be significant. Classical theory predicts that stellar discs are stabilized against bar formation if embedded in massive spheroidal dark matter halos. However, dark matter halos have been shown to facilitate the growth of bars through resonant gravitational interaction. Still, it remains unclear why some galaxies are barred and some are not. In this study, we demonstrate that co-rotating (i.e., in the same sense as the disc rotating) dark matter halos with spin parameters in the range of $0 \le λ_{\mathrm{dm}} \le 0.07$ - which are a definite prediction of modern cosmological models - promote the formation of bars and boxy bulges and therefore can play an important role in the formation of pseudobulges in a kinematically hot dark matter dominated disc galaxies. We find continuous trends for models with higher halo spins: bars form more rapidly, the forming slow bars are stronger, and the final bars are longer. After 2 Gyrs of evolution, the amplitude of the bar mode in a model with $λ_{\mathrm{dm}} = 0.05$ is a factor of ~6 times higher, A_2/A_0 = 0.23, than in the non-rotating halo model. After 5 Gyrs, the bar is ~ 2.5 times longer. The origin of this trend is that more rapidly spinning (co-rotating) halos provide a larger fraction of trailing dark matter particles that lag behind the disc bar and help growing the bar by taking away its angular momentum by resonant interactions. A counter-rotating halo suppresses the formation of a bar in our models. We discuss potential consequences for forming galaxies at high-redshift and present day low mass galaxies which have converted only a small fraction of their baryons into stars.

A 3D topological insulator quantum dot for optically controlled quantum memory and quantum computing

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We present the model of a quantum dot (QD) consisting of a spherical core-bulk heterostructure made of 3D topological insulator (TI) materials, such as PbTe/Pb$_{0.31}$Sn$_{0.69}$Te, with bound massless and helical Weyl states existing at the interface and being confined in all three dimensions. The number of bound states can be controlled by tuning the size of the QD and the magnitude of the core and bulk energy gaps, which determine the confining potential. We demonstrate that such bound Weyl states can be realized for QD sizes of few nanometers. We identify the spin locking and the Kramers pairs, both hallmarks of 3D TIs. In contrast to topologically trivial semiconductor QDs, the confined massless Weyl states in 3D TI QDs are localized at the interface of the QD and exhibit a mirror symmetry in the energy spectrum. We find strict optical selection rules satisfied by both interband and intraband transitions that depend on the polarization of electron-hole pairs and therefore give rise to the Faraday effect due to Pauli exclusion principle. We show that the semi-classical Faraday effect can be used to read out spin quantum memory. When a 3D TI QD is embedded inside a cavity, the single-photon Faraday rotation provides the possibility to implement optically mediated quantum teleportation and quantum information processing with 3D TI QDs, where the qubit is defined by either an electron-hole pair, a single electron spin, or a single hole spin in a 3D TI QD. Remarkably, the combination of inter- and intraband transition gives rise to a large dipole moment of up to 450 Debye. Therefore, the strong-coupling regime can be reached for a cavity quality factor of $Q\approx10^{4}$ in the infrared wavelength regime of around $10\:μ$m.

Studies of experimental techniques for sounding the ionosphere at low and very low radio wave frequencies

Year: 1954
Subjects: Electrical Engineering

description: Phase measurements of waves reflecting from the lower regions of the ionosphere using frequencies in the range 15 to 100 kc/s furnish a new method of investigating the effects of solar activity on radio communication.  In an effort to explore this method of measurement the Ionospheric Research Project of the California Institute of Technology constructed a complete 50-kc/s station in the Mojave desert with the transmitter near Randsburg and the receiver near Victorville.  This paper describes the equipment requirements of the station, and a paper by R.S. Macmillan (Cf. Ref. 1) will present the theoretical aspects of the data that were obtained.

A crystal-controlled transmitter was used to drive a half-wave resonant dipole, which at 50 kc/s was 8600 feet long.  The antenna pattern was such that radiated power was directed upward to the inosphere and thence back to the receiving site by means of reflection.  The necessary reference signal was sent to the receiving site by means of a very-high-frequency, frequency-modulated transmitter.

A double superheterodyne receiver received the 50-kc/s signal and converted it to 1.61 kc/s.  This output was then compared by means of a phase meter with a 1.61-kc/s reference, derived from the 50 kc/s reference signal.  The output of the phase meter was filtered (bandwidth=1 c/s) and then recorded.  A commercial field-strength meter (bandwidth= 350 c/s) was used in conjuction with this receiver to obtain the amplitude of the reflected wave.

description: For supernova powered by the conversion of kinetic energy into radiation due to the interactions of the ejecta with a dense circumstellar shell, we show that there could be X-ray analogues of optically super-luminous SNe with comparable luminosities and energetics. We consider X-ray emission from the forward shock of SNe ejecta colliding into an optically-thin CSM shell, derive simple expressions for the X-ray luminosity as a function of the circumstellar shell characteristics, and discuss the different regimes in which the shock will be radiative or adiabatic, and whether the emission will be dominated by free-free radiation or line-cooling. We find that even with normal supernova explosion energies of 10^51 erg, there exists CSM shell configurations that can liberate a large fraction of the explosion energy in X-rays, producing unabsorbed X-ray luminosities approaching 10^44 erg/s events lasting a few months, or even 10^45 erg/s flashes lasting days. Although the large column density of the circumstellar shell can absorb most of the flux from the initial shock, the most luminous events produce hard X-rays that are less susceptible to photoelectric absorption, and can counteract such losses by completely ionizing the intervening material. Regardless, once the shock traverses the entire circumstellar shell, the full luminosity could be available to observers.

Stabilizer codes are one of the most promising and straightforward ways to correct quantum errors, are convenient for logical operations, and improve performance with increasing the number of qubits involved. Here, we propose a resource-efficient scaling of a five-qubit perfect code with increasing-weight cyclic stabilizers for small distances on the ring architecture, which takes into account the topological features of the superconducting platform. We show an approach to construct the quantum circuit of a correction code with ancillas entangled with non-neighboring data qubits. Furthermore, we introduce a neural network-based decoding algorithm supported by an improved lookup table decoder and provide a numerical simulation of the proposed code, which demonstrates the exponential suppression of the logical error rate.

description: It has been known for some time that the Nakamoto consensus as implemented in the Bitcoin protocol is not totally aligned with the individual interests of the participants. More precisely, it has been shown that block withholding mining strategies can exploit the difficulty adjustment algorithm of the protocol and obtain an unfair advantage. However, we show that a modification of the difficulty adjustment formula taking into account orphan blocks makes honest mining the only optimal strategy. Surprinsingly, this is still true when orphan blocks are rewarded with an amount smaller to the official block reward. This gives an incentive to signal orphan blocks. The results are independent of the connectivity of the attacker.

description: Current surveys are underway to utilize gravitational lensing by galaxy clusters with Einstein radii >35" in the search for the highest redshift galaxies. Associated supernova from the epoch of reionization would have their fluxes boosted above the detection threshold, extending their duration of visibility. We predict that the James Webb Space Telescope (JWST) will be able to discover lensed core-collapse supernovae at redshifts exceeding z=7-8.

description: Bell's theorem is a fundamental result in quantum mechanics: it discriminates between quantum mechanics and all theories where probabilities in measurement results arise from the ignorance of pre-existing local properties. We give an extremely simple proof of Bell's inequality: a single figure suffices. This simplicity may be useful in the unending debate of what exactly the Bell inequality means, since the hypothesis at the basis of the proof become extremely transparent. It is also a useful didactic tool, as the Bell inequality can be explained in a single intuitive lecture.

Effect of orientation of a flat heating surface on nucleate boiling heat transfer
Creators: name: Githinji, Philip Mwangi

subject: FOS: Mechanical engineering

description: The object of this experimental investigation was to obtain some information on the effect of the orientation of a heating surface on boiling heat transfer and particularly on the "burnout point". This was achieved by electrically heating a chromax strip that was cemented to some refractory backing so as to limit the heat transfer to one surface of the strip. The heating unit could be rotated about the longitudinal axis, thus allowing tests to be carried out with the surface of the strip oriented upwards, downwards, and vertically. The experiments were performed in a pool of subcooled isopropyl alcohol at three bulk temperatures. The results were presented in a graphical form with the heat transfer per unit area as a function of the difference between the strip surface and the bulk fluid temperatures. The curves obtained with the strip facing upwards or in a vertical position were qualitatively similar to the characteristic boiling curve while the curve for the downward facing strip resembled one commonly associated with free convection without boiling. With the bulk temperature at 80[degrees]F, for example, the burnout heat flux for the strip facing upwards was found to be 0.31 Btu/in[superscript 2]-sec, while that for a downward facing strip was 0.62 Btu/in[superscript 2]-sec. These results indicate the necessity of considering the orientation of heating elements in the design of heat transfer equipment which is to operate in the nucleate boiling region.

description: We study the semiclassical behavior of Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam model, by taking into account of the sum over spins in the large spin regime. The large spin parameter λand small Barbero-Immirzi parameter γare treated as two independent parameters for the asymptotic expansion of spinfoam state-sum (such an idea was firstly pointed out in arXiv:1105.0216). Interestingly, there are two different spin regimes: 1<γ^{-2}. The model in two spin regimes has dramatically different number of effective degrees of freedom. In 1<γ^{-2}, only small deficit angle is allowed |Θ_f|<

description: We study the combinatorial geometry of "lattice" Jenkins--Strebel differentials with simple zeroes and simple poles on $\mathbb{C}P^1$ and of the corresponding counting functions. Developing the results of M. Kontsevich we evaluate the leading term of the symmetric polynomial counting the number of such "lattice" Jenkins-Strebel differentials having all zeroes on a single singular layer. This allows us to express the number of general "lattice" Jenkins-Strebel differentials as an appropriate weighted sum over decorated trees. The problem of counting Jenkins-Strebel differentials is equivalent to the problem of counting pillowcase covers, which serve as integer points in appropriate local coordinates on strata of moduli spaces of meromorphic quadratic differentials. This allows us to relate our counting problem to calculations of volumes of these strata . A very explicit expression for the volume of any stratum of meromorphic quadratic differentials recently obtained by the authors leads to an interesting combinatorial identity for our sums over trees.
