On TCS $G_2$ manifolds and 4D Emergent Strings

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this note, we study the Swampland Distance Conjecture in TCS $G_2$ manifold compactifications of M-theory. In particular, we are interested in testing a refined version -- the Emergent String Conjecture, in settings with 4d $N=1$ supersymmetry. We find that a weakly coupled, tensionless fundamental heterotic string does emerge at the infinite distance limit characterized by shrinking the $K3$-fibre in a TCS $G_2$ manifold. Such a fundamental tensionless string leads to the parametrically leading infinite tower of asymptotically massless states, which is in line with the Emergent String Conjecture. The tensionless string, however, receives quantum corrections. We check that these quantum corrections do modify the volume of the shrinking K3-fibre via string duality and hence make the string regain a non-vanishing tension at the quantum level, leading to a decompactification. Geometrically, the quantum corrections modify the metric of the classical moduli space and are expected to obstruct the infinite distance limit. We also comment on another possible type of infinite distance limit in TCS $G_2$ compactifications, which might lead to a weakly coupled fundamental type II string theory.

description: We investigate the behaviour of the two-point correlation function in the context of passive scalars for non homogeneous, non isotropic forcing ensembles. Exact analytical computations can be carried out in the framework of the Kraichnan model for each anisotropic sector. It is shown how the homogeneous solution is recovered at separations smaller than an intrinsic typical lengthscale induced by inhomogeneities, and how the different Fourier modes in the centre-of-mass variable recombine themselves to give a ``beating'' (superposition of power laws) described by Bessel functions. The pure power-law behaviour is restored even if the inhomogeneous excitation takes place at very small scales.

description: Massive bosons, such as light scalars and vector bosons, can lead to instabilities of rotating black holes by the superradiance effect, which extracts energy and angular momentum from rapidly-rotating black holes effectively. This process results in spinning-down of black holes and the formation of boson clouds around them. In this work, we used the masses and spins of supermassive black holes measured from the ultraviolet/optical or X-ray observations to constrain the model parameters of the light bosons. We find that the mass range of light bosons from $10^{-22}$ eV to $10^{-17}$ eV can be largely excluded by a set of supermassive black holes (including also the extremely massive ones OJ 287, Ton 618 and SDSS J140821.67+025733.2), particularly for the vector boson scenario, which eliminates a good fraction of the so-called fuzzy dark matter parameter regions. For the scalar bosons with self-interaction, most part of the mass range from $\sim 3 \times 10^{-19}$ eV to $10^{-17}$ eV with a decay constant $f_a > 10^{15}$ GeV can be excluded, which convincingly eliminate the QCD axions at these masses.

description: Photovoltaic cell is an electrical device that is capable of convert the light energy received from the sun directly into the electrical energy, but this energy is generated at very low voltage levels. For this reason, the series connection of these cells is used to build photovoltaic modules to increase the output voltage levels. Farther, the series and parallel connection of these modules can be used to create a photovoltaic array that can generate high power at higher voltage levels. The most important issue in a photovoltaic array is to reach the maximum amount of power in its output. There are several methods to achieve this amount of power in the uniform radiation conditions. The great challenge in maximum power tracking is that the modules in an array experience non-uniform radiation, which is called as partial shading conditions. In this situation, the power-voltage (P-V) curve offers several local maximum power point and the use of conventional maximum power point tracking algorithms in uniform radiation conditions dose not guarantee to achieve the global maximum power point. In this research, a new method for tracking the maximum power of photovoltaic arrays under partial shading conditions based on photovoltaic array model is proposed. In this method, without need to the numerical solution of the nonlinear equations of the PV array, the global maximum power point voltage is estimated. The global peak point voltage obtained at each instant is given as a reference voltage to the input voltage controller of a power electronic converter, and therefore the output voltage of the photovoltaic array is set at the global peak point voltage in different radiation conditions. The radiation and temperature of the modules are estimated and there is no need for pyranometers and thermometers to determine the radiation and temperature of each module. The satisfactory operation of the proposed method under various irradiation patterns for the photovoltaic array shown by the MATLAB/Simulink software.

description: The number and use of research-based assessments (RBAs) has grown significantly over the last several decades. Data from RBAs can be compared against national datasets to provide instructors with empirical evidence on the efficacy of their teaching practices. Many physics instructors, however, opt not to use RBAs due to barriers such as having to use class time to administer them. In this article we examine how these barriers can be mitigated through online administrations of RBAs, particularly through the use of free online RBA platforms that automate administering, scoring, and analyzing RBAs (e.g., the Learning About STEM Student Outcomes [LASSO], Colorado Learning Attitudes About Science Survey for Experimental Physics [E-CLASS], Physics Lab Inventory of Critical thinking [PLIC], and PhysPort DataExplorer platforms). We also explore the research into common concerns of administering RBAs online and conclude with a practical how-to guide for instructors.

description: In this era where every field of life is rapidly growing and developing, it is too difficult rather impossible for a country to finance all developing expenditures with its own resources. So to cop up with this problem of insufficient revenue for expenditure, the country borrows money from internal as well as from external resources. In certain limits this practice is normal, but during last few decades it has been noticed that debts are growing extraordinary in all countries generally but particularly in under developed countries. The rationale of this research is to elaborate the impact of debt crises on the economy of developing countries. Recent crises in developing countries have demonstrated the weakness of real sectors to changes in financial market conditions. Better management of government’s balance sheet may significantly decrease the frequency of debt crises. The outbreak of the developing countries debt crises has realized to the people that immense increase in public debt has turned out a serious problem.

We illustrate preliminary results of a lattice determination of $ξ$ for the case of pure Yang-Mills with two colors, obtained by measuring the temporal correlator of a disorder parameter detecting dual superconductivity.

description: A demand system model differentiating goods by origin is developed to examine impacts of duty drawback on U.S. orange juice exports and prices. An empirical analysis suggests that on average duty drawback has increased annual orange juice exports by about 16.5 million SSE gallons or 11% of export sales, and has supported the U.S. price of orange juice by about 2 cents per gallon. Not all benefits of duty drawback go to exporters. Importers who own drawback credits but do not export product may realize benefits by selling their credits to exporters. The analysis suggests these benefits effectively reduce by the U.S. orange juice tariff, positively impacting imports and negatively impacting the U.S. price.

description: The thesis explores the ways in which economic and architectural practices, embedded systems and forms of adaptation enrich and erode modernist practices in Maputo. The paper looks at the planning, economic processes and policies and their resulting urban and architectural manifestations, by exploring how endogenous forms and systems contrast with, intertwine, and coexist with modernist practices. From utopian visions to cemented realities, the first chapter analyses the ensuing plans and projects in order to better understand the underlying ideologies examining their demise, their successes and their subsequent appropriation. The following chapter shines light on the way architectural and urban practices, stemming from specific socio-economic conditions and embedded forms of adaptation contrast with, erode, and at times enrich, earlier modernist practices. The last chapter studies how formal and ‘informal’ methods interweave and can coexist. The proposal reconsiders both practices; high modernist and endogenous, which are seemingly antagonistic, as legitimate ways of engaging with planning and transforming the city.

description: We present a characterization of the physical properties of a sample of 35 securely-detected, dusty galaxies in the deep ALMA 1.2-mm image obtained as part of the ALMA Spectroscopic Survey in the {\it Hubble} Ultra Deep Field (ASPECS) Large Program. This sample is complemented by 26 additional sources identified via an optical/infrared source positional prior. Using their well-characterized spectral energy distributions, we derive median stellar masses and star formation rates (SFR) of $4.8\times10^{10}~M_\odot$ and 30 $M_\odot$ yr$^{-1}$, and interquartile ranges of $(2.4-11.7)\times10^{10}~M_\odot$ and $20-50~M_\odot$ yr$^{-1}$, respectively. We derive a median spectroscopic redshift of 1.8 with an interquartile range $1.1-2.6$, significantly lower than submillimeter galaxies detected in shallower, wide-field surveys. We find that 59\%$\pm$13\%, 6\%$\pm$4\%, and 34\%$\pm$9\% of our sources are within, above and below $\pm0.4$ dex from the SFR-stellar mass relation or main-sequence (MS), respectively. The ASPECS galaxies closely follow the SFR-molecular gas mass relation and other previously established scaling relations, confirming a factor of five increase of the gas-to-stellar mass ratio from $z=0.5$ to $z=2.5$ and a mild evolution of the gas depletion timescales with a typical value of 0.7 Gyr at $z=1-3$. ASPECS galaxies located significantly below the MS, a poorly exploited parameter space, have low gas-to-stellar-mass ratios of $\sim0.1-0.2$ and long depletion timescales $>1$ Gyr. Galaxies along the MS dominate the cosmic density of molecular gas at all redshifts. Systems above the main sequence have an increasing contribution to the total gas reservoirs from $z<1$ to $z=2.5$, while the opposite is found for galaxies below the MS.

Transverse beam polarization and limits on leptoquark couplings in e+e- --> t tbar

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: It is shown that if electron and positron beams at a linear collider are transversely polarized, azimuthal asymmetries of the final-state top quark in e+e- --> t tbar can be used to probe a combination of couplings of left and right chiralities in a scalar leptoquark model. The CP-conserving azimuthal asymmetry would be a sensitive test of the chirality violating couplings. A linear collider operating at sqrt{s}=500 GeV and having transverse polarizations of 80% and 60% respectively for the e- and e+ beams, can put a limit of the order of 0.025 on the product of the left and right chirality leptoquark couplings (in units of the electromagnetic coupling constant), with a leptoquark mass of 1 TeV and for an integrated luminosity of 500 inverse fb. The CP-violating azimuthal asymmetry, which would provide a direct test of CP-violating phases in leptoquark couplings, can be constrained to the same level of accuracy. However, this limit is uninteresting in view of the much better indirect limit from the electric dipole moment of the electron.

description: Torsion adapters in lower limb prostheses aim to increase comfort, mobility and health of users by allowing rotation in the transversal plane. A preliminary study with two transtibial amputees indicated correlations between torsional stiffness and foot alignment to increase comfort and stability of the user depending on the gait situation and velocity. This paper presents the design and proof-of-concept of an active, bio-inspired prosthetic shank adapter and a novel approach to create a user-specific human-machine interaction through adapting the device’s properties. To provide adequate support, load data and subjective feedback of subjects are recorded and analyzed regarding defined gait situations. The results are merged to an user individual preference-setting matrix to select optimal parameters for each gait situation and velocity. A control strategy is implemented to render the specified desired torsional stiffness and transversal foot alignment values to achieve situation-dependent adaptation based on the input of designed gait detection algorithms. The proposed parallel elastic drive train mimics the functions of bones and muscles in the human shank. It is designed to provide the desired physical human-machine interaction properties along with optimized actuator energy consumption. Following test bench verification, trials with five participants with lower limb amputation at different levels are performed for basic validation. The results suggest improved movement support in turning maneuvers. Subjective user feedback confirmed a noticeable reduction of load at the stump and improved ease of turning.
Ring expansion reactions to form spirocycles and its application to the synthesis of cylindricine B
Creators: name: Fleury, Melissa
Publisher: name: University of British Columbia
Year: 2009

description: The photochemically initiated semipinacol rearrangement of a substrate bearing an intramolecular alcohol 1.10 was attempted in order to provide spirocyclic ring systems. The syntheses of carbocyclic ring expansion precursors were achieved. Unfortunately, the use of U V light and a photosensitizer to initiate ring expansion reaction was unsuccessful. It was found that a majority of siloxy-epoxide ring expansions of cyclobutane rings to form l-azaspiro[5.4]decanes are unselective. The ring expansion of cyclobutane rings was executed on siloxy-epoxide carbocycles 2.6 and 2.15 and heterocycle 2.34 with the intent of achieving mechanistic elucidation. Three scenarios for the stereochemical outcome of the rearrangements were examined. The rearrangement was deduced to most likely occur via an unselective synchronous mechanism where anti and syn migration of the alkyl (CHfe) group onto the epoxide moiety take place to give 2.4 and 2.5, respectively. Interesting diastereoselectivity was observed by varying the silicon substituent size and the substitution at the 3-position of the heterocycle. Also, chiral Lewis acid initiated ring expansions were attempted as a method of introducing asymmetry. Finally, synthesis of the A ring of cylindricine B via nitrogen addition (Michael reaction) onto an a,8-unsaturated carbonyl 3.7 was attempted. The synthesis of the B and C ring framework was executed following group precedent. The synthesis of the a,6-unsaturated carbonyl side chain was attempted using Kishi-Nozaki and carbonylative Stille coupling reactions on an azaspirocyclic vinyl triflate 3.1. The Michael acceptor side chain was not successfully appended using these coupling reactions. The synthesis of the A ring is key in performing the first asymmetric total synthesis of cylindricine B. Therefore, further investigations on appending the Michael acceptor side chain are necessary in order to achieve this goal.

description: We reexamine in detail a canonical quantization method a la Gupta-Bleuler in which the Fock space is built over a so-called Krein space. This method has already been successfully applied to the massless minimally coupled scalar field in de Sitter spacetime for which it preserves covariance. Here, it is formulated in a more general context. An interesting feature of the theory is that, although the field is obtained by canonical quantization, it is independent of Bogoliubov transformations. Moreover no infinite term appears in the computation of $T^{μν}$ mean values and the vacuum energy of the free field vanishes: $<0|T^{00}|0>=0$. We also investigate the behaviour of the Krein quantization in Minkowski space for a theory with interaction. We show that one can recover the usual theory with the exception that the vacuum energy of the free theory is zero.

description: Although ammonia is a widely used interstellar thermometer, the estimation of its rotational and kinetic temperatures can be affected by the blended Hyperfine Components (HFCs). We developed a new recipe, referred to as the HyperFine Group Ratio (HFGR), which utilizes only direct observables, namely the intensity ratios between the grouped HFCs. As tested on the model spectra, the empirical formulae in HFGR can derive the rotational temperature ($T_{\rm rot}$) from the HFC group ratios in an unambiguous manner. We compared HFGR with two other classical methods, intensity ratio and hyperfine fitting, based on both simulated spectra and real data. HFGR has three major improvements. First, HFGR does not require modeling the HFC or fitting the line profiles, thus is more robust against the effect of HFC blending. Second, the simulation-enabled empirical formulae are much faster than fitting the spectra over the parameter space, so the computer time and human time can be both largely saved. Third, the statistical uncertainty of the temperature $ΔT_{\rm rot}$ as a function of the signal-to-noise ratio (SNR) is a natural product of the HFGR recipe. The internal error of HFGR is $ΔT_{\rm rot}\leq0.5$ K over a broad parameter space of rotational temperature (10 to 60 K), line width (0.3 to 4 km/s), and optical depth (0 to 5). When there is a spectral noise, HFGR can also maintain a reasonable uncertainty level at $ΔT_{\rm rot}\leq 1.0$ K (1 $σ$) when SNR > 4.

description: Mesenchymal stem cells (MSCs) possess huge potential for regenerative medicine. For tissue engineering approaches, scaffolds and hydrogels are routinely used as extracellular matrix (ECM) carriers. The present study investigated the feasibility of using textile-reinforced hydrogels with adjustable porosity and elasticity as a versatile platform for soft tissue engineering. A warp-knitted poly (ethylene terephthalate) (PET) scaffold was developed and characterized with respect to morphology, porosity, and mechanics. The textile carrier was infiltrated with hydrogels and cells resulting in a fiber-reinforced matrix with adjustable biological as well as mechanical cues. Finally, the potential of this platform technology for regenerative medicine was tested on the example of fat tissue engineering. MSCs were seeded on the construct and exposed to adipogenic differentiation medium. Cell invasion was detected by two-photon microscopy, proliferation was measured by the PrestoBlue assay. Successful adipogenesis was demonstrated using Oil Red O staining as well as measurement of secreted adipokines. In conclusion, the given microenvironment featured optimal mechanical as well as biological properties for proliferation and differentiation of MSCs. Besides fat tissue, the textile-reinforced hydrogel system with adjustable mechanics could be a promising platform for future fabrication of versatile soft tissues, such as cartilage, tendon, or muscle.
Investigations of atherosclerotic coronary arteries by confocal raman microspectroscopy

description: Atherosclerosis is a vascular disease, initiated by damage to the endothelial cells, and characterized by the deposition of plaque, which composes of mainly lipids and cholesterol, in the inner arterial wall that leads to progressive narrowing and hardening of the artery. The assessment of plaque status for the prediction of disease progression requires the examination of plaque's composition and structure rather than its size or gross morphology. Recent studies have shown Raman spectroscopy to be well suited for diagnosis of tissues because of its ability to identify and quantify biochemical molecules and structural motifs within intact cells. The ultimate utility of Raman technique may lie in its potential for the real-time assessment of atherosclerosis in vivo using fiber optic probes. This project employed confocal Raman microspectroscopy for the study of normal and diseased human coronary artery specimens in situ. A new Raman microscopy system for tissue spectroscopy has been set-up and characterized. Raman spectra were collected at various locations of the arterial wall, either along the radius covering its different layers, or concentrically outward from the lumen. Numerous algorithms were developed and tested for baseline removal, normalization and smoothing of Raman spectra obtained. Key analysis involving component analysis and generalized two-dimensional (2D) correlation followed. A model for chemical component analysis of eighteen major biochemicals found in the tissue/plaque was developed based on the application of singular value decomposition (SVD). Quantitative information on the relative amount of individual biomolecule was provided by the component analysis in which each Raman artery spectrum was modeled to a set of eighteen biochemical basis spectra. Generalized 2D Raman correlation spectroscopy was employed to identify and classify variations in spectral features occurring at different locations of the artery transverse section. The 2D correlation results have demonstrated the ability of 2D correlation to detect subtle spectral changes happening within a tiny area of the arterial wall, as well as to provide qualitative information about the order of appearance of individual constituent that complemented the chemical composition results. Possible future improvements and continuation of the project were proposed in the final chapter of this thesis as well.

description: Solar photovoltaic energy generation is expected to grow dramatically in coming years in order to take advantage of renewable and clean sources of electricity. This thesis presents research on the impact of increasing solar PV penetration, specifically of large, utility-scale PV facilities, on transmission network performance. The development of Python programming tools for automation of power flow analysis is presented. A modified version of the IEEE 118-Bus test system is developed and modified to simulate increasing PV generation on the transmission system. The impacts on performance are analyzed trends are reported. Battery energy storage systems are studied in this thesis for their ability to regulate system voltages through reactive power support. The modified IEEE test case is used as a basis to present a developed method for optimization of the location of battery systems for voltage support.

description: We present a unified approach to quantum error correction, called operator quantum error correction. This scheme relies on a generalized notion of noiseless subsystems that is not restricted to the commutant of the interaction algebra. We arrive at the unified approach, which incorporates the known techniques -- i.e. the standard error correction model, the method of decoherence-free subspaces, and the noiseless subsystem method -- as special cases, by combining active error correction with this generalized noiseless subsystem method. Moreover, we demonstrate that the quantum error correction condition from the standard model is a necessary condition for all known methods of quantum error correction.

Single-spin asymmetries in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target
Creators: name: The HERMES Collaboration
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polarization. The asymmetry depends on the azimuthal angles of both the pion ($ϕ$) and the target spin axis ($ϕ_S$) about the virtual photon direction and relative to the lepton scattering plane. The extracted Fourier component $\cmpi$ is a signal of the previously unmeasured quark transversity distribution, in conjunction with the so-called Collins fragmentation function, also unknown. The Fourier component $\smpi$ of the asymmetry arises from a correlation between the transverse polarization of the target nucleon and the intrinsic transverse momentum of quarks, as represented by the previously unmeasured Sivers distribution function. Evidence for both signals is observed, but the Sivers asymmetry may be affected by exclusive vector meson production

description: Index modulation (IM) is one of the candidate technologies for the upcoming sixth generation (6G) wireless communications networks. In this paper, we propose a space-time-modulated reconfigurable intelligent metasurface (RI-MTS) that is configured to implement various frequency-domain IM techniques in a multiple-input multiple-output (MIMO) array configuration. Unlike prior works which mostly analyze signal theory of general RI-MTS IM, we present novel electromagnetics-compliant designs of specific IMs such as sub-carrier index modulation (SIM) and MIMO orthogonal frequency-domain modulation IM (MIMO-OFDM-IM). Our full-wave electromagnetic simulations and analytical computations establish the programmable ability of these transceivers to vary the reflection phase and generate frequency harmonics for IM. Our experiments for bit error rate show that RI-MTS-based SIM and MIMO-OFDM-IM are lower than conventional MIMO-OFDM.
