description: The $AdS_3\times S^3$ string sigma model supported both by NS-NS and R-R fluxes has become a well known integrable model, however a putative dual field theory description remains incomplete. We study the anomalous dimensions of twist operators in this theory via semiclassical string methods. We describe the construction of a multi-cusp closed string in conformal gauge moving in $AdS_3$ with fluxes, which supposedly is dual to a general higher twist operator. After analyzing the string profiles and conserved charges for the string, we find the exact dispersion relation between the charges in the `long' string limit. This dispersion relation in leading order turns out to be similar to the case of pure RR flux, with the coupling being scaled by a factor that depends on the amount of NS-NS flux turned on. We also analyse the case of pure NS flux, where the dispersion relation simplifies considerably. Furthermore, we discuss the implications of these results at length.

description: This contribution examines the question of how contemporary lyric poetry expands upon established generic concepts by considering the work of Monika Rinck, one of the most striking voices among a generation of exceedingly talented poets who made their debut in the 2000s. In her poetry, we find numerous examples of how the expectations of lyric are deliberately undermined: among them, formal features reminiscent of prose, such as her tendency to use extremely long lines and prose-typical abbreviations, as well as her explicit interest in the discursive exploration of ‘concepts.’ As her essays suggest, this interest manifests itself most readily in Rinck’s efforts to avoid the totalizing economization of society (as well as art and language) and has, as a result, motivated the development of her own style within experimental language poetry. However, while Rinck has played a leading role in expanding the contemporary concept of poetry, the poetic principles to which she refers in her theoretical writings and poems are by no means new. In this article, her poem „Augenfühlerfisch“ (“eye-tentacle fish”) serves not only to illustrate her tendency to expand poetry into discursive prose but demonstrates how it is rooted in a long-standing philosophical tradition. The terminology used in the poem can be traced back to early modern epistemology and particularly to the foundation of scientific aesthetics by Alexander Gottlieb Baumgarten. In referring to Baumgarten’s definition of poetry as “fully sensuous speech [vollkommen sinnliche Rede]” (as well as the specific deployment of this definition by Johann Adolf Schlegel), it becomes clear that Rinck reactivates an epistemological potential in lyric that had been hidden by the paradigm of Erlebnislyrik [experiential lyric]. Moreover, Rinck is able to relax the Erlebnislyrik’s pretense to sincerity in part thanks to the same prose features, such as the multiplication of voices, already mentioned above.

description: The tribological behaviors of silicon nitride sliding upon sintered polycrystalline diamond (PCD) were explored via altering pH levels. High reductions in the friction and wear are achieved when sodium hydroxide solution is introduced at the contact interfaces. This reduction is found to depend on the pH value of the alkaline solution. The friction coefficient and wear loss of silicon nitride vary with pH level by more than half an order of magnitude and achieves the lowest values at pH 13. Moreover, the tribological behaviors reveal three stages versus the pH level, for which different tribochemical reactions occur due to the dissimilar hydroxyl concentrations. The dissolution of reaction products, such as Si(OH)4 and dimers (OH)3Si-O-C(OH)3, might lead to an increased proportion of hydrodynamic lubrication in the mixed lubrication regime and hence yield reduced friction and wear.

description: The standard Bloch oscillation normally refers to the oscillatory tunneling dynamics of quantum particles in a periodic lattice plus a linear gradient. In this work we theoretically investigate the generalized form of the Bloch oscillation in the presence of additional higher order gradients, and demonstrate that the higher order gradients can significantly modify the tunneling dynamics, particularly in the spectrum of the density oscillation. The spectrum of the standard Bloch oscillation is composed of a single prime frequency and its higher harmonics, while the higher-order gradients in the external potential give rise to fine structures in the spectrum around each of these Bloch frequencies, which are composed of serieses of frequency peaks. Our investigation leads to a twofold consequence to the applications of Bloch oscillations for measuring external forces: For one thing, under a limited resolution of the measured spectrum, the fine structures would manifest as a blur to the spectrum, and leads to intrinsic errors to the measurement. For another, given that the fine structures could be experimentally resolved, they can supply more information of the external force than the strength of the linear gradient, and be used to measure more complicated forces.

description: The new field of spin cavitronics focuses on the interaction between the magnon excitation of a magnetic element and the electromagnetic wave in a microwave cavity. In strong interaction regime, such interaction usually gives rise to the level anti-crossing for the magnonic and the electromagnetic mode. Recently, the attractive level crossing has been observed, and is explained by a non-Hermitian model Hamiltonian. However, the mechanism of the such attractive coupling is still unclear. Here we reveal the secret by using a simple model with two harmonic oscillators coupled to a third oscillator with large dissipation. We further identify this dissipative third-party as the invisible cavity mode with large leakage in the cavity-magnon experiments. This understanding enables designing dissipative coupling in all sorts of coupled systems.

description: High-temperature tribology of steel components is typically characterized by high friction and excessive wear, which need to be addressed. In the present study, the tribological properties of an alkali borate were evaluated in a steel contact by ball-on-disc testing over a wide range of temperatures (600–800 °C) and loads. The compound exhibits good lubrication performance consistently throughout the whole testing range. On the rubbing disc, the formation of a tribofilm with a hierarchical structure is the determining factor for the friction-reducing and wear-inhibiting capacity of the lubricant. Worn surfaces were characterized by scanning electron microscopy (SEM) and cross-sectional observations of the tribo-interface were accomplished by scanning transmission electron microscopy (STEM) coupled with energy-dispersive spectroscopy (EDS). Secondary ion mass spectroscopy (SIMS) was employed to generate an elemental depth profile of the lubricated surface.
Characterisation of tissue-specific promoter regions within Aedes aegypti

description: Vector-borne illnesses make up 17% of global infections, with Aedes aegypti playing a significant role in their spread. Current genetic population control strategies function inter-generationally — suppressing future mosquito generations once released —allowing for extended periods of disease spread before population suppression occurs. A new methodology, toxic male technique (TMT), utilises tissue-specific expression of ion-channel targeting venom peptides within insect seminal fluid — transferred to females via mating — inducing female lethality. A proof of concept for TMT has been demonstrated in Drosophila melanogaster and modelling its implementation in Ae. aegypti indicates more rapid population suppression and bloodmeal reduction compared to other biocontrol methods.Engineering TMT within Ae. aegypti requires characterisation of promoters specific to the male accessory glands (MAGs), organs responsible for production of seminal fluid proteins (SFPs), transferred from males to females via mating. We characterised promoters of three, possibly four SFP encoding genes, AAEL024630, AAEL023599, AAEL013449, and AAEL006418, demonstrating a range of expression levels and tissue-specificity within the MAGs of Ae. aegypti. We accomplished this through engineering transgenic mosquito lines to express a reporter gene under control of a promoter candidate, using fluorescence microscopy and western immunoblotting to screen for presence and tissue-specificity. Successful characterisation brings intra-generational biocontrol in mosquitoes one step closer.

description: Using data from a Canadian national survey assessing dairy product preferences in 2011, individual preferences for milk and yogurts with specific attributes are examined in this study. Statements developed based on the Health Belief Model, food attitudes, beliefs about the role that nutrition plays in health, nutrition knowledge, and an individual’s propensity to make changes to improve their health are used to predict whether or not respondents consume milk/yogurt, the frequency with which they consume it, which type of product they typically consume, and how much they would be willing to pay for new milk or yogurt attributes. Results indicate that several aspects of the Health Belief Model as well as general nutrition knowledge can predict purchasing and consumption intentions for milk and yogurt products. All else being equal, the influences on an individual’s willingness to pay for unique milk or yogurt characteristics in stated choices are different then the influences on their self-identified willingness to seek out milk or yogurt to increase calcium in their diet.

description: Abstract: The role of rotational molecular motors of the ATP synthase class is integral to the metabolism of cells. Yet the function of FliI6-FliJ complex, a homolog of the F1 ATPase motor, within the flagellar export apparatus remains unclear. We use a simple two-state model adapted from studies of linear molecular motors to identify key features of this motor. The two states are the ‘locked’ ground state where the FliJ coiled coil filament experiences angular fluctuations in an asymmetric torsional potential, and a ‘free’ excited state in which FliJ undergoes rotational diffusion. Michaelis-Menten kinetics was used to treat transitions between these two states, and obtain the average angular velocity of the unloaded FliJ filament within the FliI6 stator: ωmax ≈ 9.0 rps. The motor was then studied under external counter torque conditions in order to ascertain its maximal power output: Pmax ≈ 42 kBT/s (or 102 kW/mol), and the stall torque: Gstall ≈ 3 kBT/rad (or 0.01 nN·nm/rad). Two modes of action within the flagellar export apparatus are proposed, in which the motor performs useful work either by continuously ‘grinding’ through the resistive environment of the export gate, or by exerting equal and opposite stall force on it. In both cases, the resistance is provided by flagellin subunits entering the flagellar export channel prior to their unfolding. We therefore propose that the function of the FliI6-FliJ complex is to lower the energy barrier, and therefore assist in unfolding of the flagellar proteins before feeding them into the transport channel.

description: Abstract: Blindness leads to substantial enhancements in many auditory abilities, and deficits in others. It is unknown how severe visual losses need to be before changes in auditory abilities occur, or whether the relationship between severity of visual loss and changes in auditory abilities is proportional and systematic. Here we show that greater severity of visual loss is associated with increased auditory judgments of distance and room size. On average participants with severe visual losses perceived sounds to be twice as far away, and rooms to be three times larger, than sighted controls. Distance estimates for sighted controls were most accurate for closer sounds and least accurate for farther sounds. As the severity of visual impairment increased, accuracy decreased for closer sounds and increased for farther sounds. However, it is for closer sounds that accurate judgments are needed to guide rapid motor responses to auditory events, e.g. planning a safe path through a busy street to avoid collisions with other people, and falls. Interestingly, greater visual impairment severity was associated with more accurate room size estimates. The results support a new hypothesis that crossmodal calibration of audition by vision depends on the severity of visual loss.

description: Urea, NH2C(O)NH2, is a molecule of great importance in organic chemistry and biology. Two searches for urea in the interstellar medium were reported in the past, but neither were conclusive. We want to take advantage of the increased sensitivity and angular resolution provided by ALMA to search for urea toward the hot cores embedded in the high-mass star forming region Sgr B2(N). We use the new spectral line survey ReMoCA performed toward Sgr B2(N) with ALMA in its observing cycle 4. The spectra are analyzed under the LTE approximation. We construct a full synthetic spectrum that includes all the molecules identified so far. We use new spectroscopic predictions for urea in its vibrational ground state and first vibrationally excited state to search for this complex organic molecule in the ReMoCA data set. We employ the gas-grain chemical kinetics model MAGICKAL to interpret the astronomical observations. We report the secure detection of urea toward the hot core Sgr B2(N1) at a position called N1S slightly offset from the continuum peak, which avoids obscuration by the dust.. We derive a column density of 2.7x10^16 cm-2 for urea, two orders of magnitude lower than formamide, and one order of magnitude below methyl isocyanate, acetamide, and N-methylformamide. The latter molecule is reliably identified toward N1S with 60 clearly detected lines, confirming an earlier claim of its tentative interstellar detection. We report the first interstellar detections of NH2CH18O and 15NH2CHO. We also report the nondetection of urea toward the secondary hot core Sgr B2(N2) with an abundance relative to the other four species at least one order of magnitude lower than toward the main hot core. Our chemical model roughly reproduces the relative abundances of formamide, methyl isocyanate, acetamide, and N-methylformamide, but it overproduces urea by at least one order of magnitude.

description: We present results for the mass of the etaprime meson for two-flavor lattice QCD in the continuum limit, calculated on the CP-PACS computer, using an RG-improved gauge action and clover fermion action with tadpole-improved csw. Measurements are made at three couplings corresponding to a approx. 0.22, 0.16, 0.11 fm for four quark masses corresponding to mpi over mrho approx. 0.8, 0.75, 0.7, 0.6. Thw two-loop diagrams are evaluated using a noisy source method. Quark smearing for both one- and two- loop diagrams is successfully applied to obtain ground state signals in the etaprime channel. We obtain metaprime=0.960(87)+0.036-0.286GeV in the continuum limit, where the second error represents the systematic uncertainty coming from varying the functional form for chiral and continuum extrapolations.

description: Abstract: Recent increases in marijuana use and legalization without adequate knowledge of the risks necessitate the characterization of the billions of nanoparticles contained in each puff of smoke. Tobacco smoke offers a benchmark given that it has been extensively studied. Tobacco and marijuana smoke particles are quantitatively similar in volatility, shape, density and number concentration, albeit with differences in size, total mass and chemical composition. Particles from marijuana smoke are on average 29% larger in mobility diameter than particles from tobacco smoke and contain 3.4× more total mass. New measurements of semi-volatile fractions determine over 97% of the mass and volume of the particles from either smoke source are comprised of semi-volatile compounds. For tobacco and marijuana smoke, respectively, 4350 and 2575 different compounds are detected, of which, 670 and 536 (231 in common) are tentatively identified, and of these, 173 and 110 different compounds (69 in common) are known to cause negative health effects through carcinogenic, mutagenic, teratogenic, or other toxic mechanisms. This study demonstrates striking similarities between marijuana and tobacco smoke in terms of their physical and chemical properties.

description: I construct a New Keynesian DSGE model featuring household consumption of intermediate goods and double marginalization. Without double marginalization, the central bank should target sticky-price inflation only, even if sticky-price goods are made from flexible-price consumption goods. With double marginalization, the first- best allocation is no longer attainable. To analyze the welfare implications of these two features, I report the expected period welfare losses of the Taylor rule and the optimal monetary policy in Huang and Liu (2005). When there is household consumption of intermediate goods, ignoring double marginalization leads to an underestimation of the welfare losses of the Taylor Rule by nearly one third, or 0.38% of the steady state consumption level. When there is double marginalization, considering household consumption of intermediate goods and re-optimizing weights on inflation rates in different sectors will improve the performance of the optimal monetary policy in Huang and Liu (2005) by about 6.5%, or 0.0025% of the steady state consumption level.
Machine learning-Enabled Multi-scale Process Monitoring and Development for Metal Additive Manufacturing

description:  The variability in the printing outcome of additive manufacturing of metals is a major obstacle that hinders the reliance on the quality of printed parts and thus the potential for full production. In-situ monitoring coupled with machine learning can save labor-intensive costs and time-consuming ex-situ work by enabling accelerated process design that targets consistent printing quality. To that end, this dissertation proposes smart monitoring approaches at the melt-pool scale and part scale through high-speed imaging and IR thermal imaging for the process development, identification of defects formation, and analysis of the humping-up phenomenon as one of the major surface defects.
We start by looking into the global effect of heat accumulation and monitoring the process at the part scale by using IR thermal imaging as the most convenient thermal monitoring. An unsupervised machine learning-based method is developed to detect heat accumulation in real-time without the need to spend a long time labeling millions of images. Furthermore, we have developed an approach to generate thermal distribution given the laser toolpath by using generative deep learning. We have investigated the effect of the parameters of the scanning strategy on thermal distribution. Finally, we zoom into the process and track the molten pool of metal as the laser moves to dive into the local aspects of the process.

In particular the model is shown to accurately predict that: (i) the extent of cell spreading, actin polymerisation as well as the traction forces that cells exert increase with increasing stiffness of the foundation; (ii) the traction forces that cells exert are primarily concentrated along the cell periphery; and (iii) while the total tractions increase with increasing cell area the average tractions are reasonably independent of cell area, i.e. for a given substrate stiffness, the average tractions that are normalized by cell area do not vary strongly with cell size. These results thus suggest that the increased foundation stiffness causes both the cell area and the average tractions that the cells exert to increase through higher levels of stress-fibre polymerization rather than the enhanced total tractions being directly linked through causation to the larger cell areas. A defining feature of the model is that its predictions are statistical in the form of probability distributions of observables such as the traction forces and cell area. In contrast, most existing models present solutions to specific boundary value problems where the cell morphology is imposed a priori. In particular, in line with observations we predict that the diversity of cell shapes, sizes and measured traction forces increase with increasing foundation stiffness. The homeostatic mechanics framework thus suggests that the diversity of observations in in vitro experiments is inherent to the homeostatic equilibrium of cells rather than being a result of experimental errors.

description: We apply a recent proposal to speed up the Hybrid-Monte-Carlo simulation of systems with dynamical fermions to two flavour QCD with clover-improvement. The basic idea of our proposal is to split the fermion matrix into two factors with a reduced condition number each. In the effective action, for both factors a pseudo-fermion field is introduced. For our smallest quark masses we see a speed-up of more than a factor of two compared with the standard algorithm.

description: This paper uses a randomized field experiment to identify the spillover effects of increased formal savings-use on non-farm business activity and production decisions of non-savers in villages. A panel analysis of 2,006 households in Central Malawi shows that a randomly assigned formal savings encouragement exogenously increases adoption of high-liquidity formal savings accounts in village communities. This increases receipts of cash assistance by non-saving households in the middle wealth-stratum, who may be on the margins for deciding to operate a non-farm business, or start growing cash crops or high-yielding crop varieties (HYVs). The hypothesized channel of effects is that expanded formal savings-use increases liquidity and decreases transaction costs, lowers the cost of making transfers, and thus increases receipts of cash aid even by non-saving households. Increased cash assistance is then linked among these households to increased probability of operating a non-farm enterprise or switching to HYVs or cash crops. This may result from a perception of increased security, which causes households to be more willing to take on higher-risk, higher-reward production activities. To date, little is known about how microfinance affects pre-existing informal insurance practices, and whether the production choices among those who utilize informal practices change as safety nets based on inter-household transfers strengthen or weaken when financial markets expand. This paper helps fill that gap.

description: Brillouin scattering has applications ranging from signal processing, sensing and microscopy, to quantum information and fundamental science. Most of these applications rely on the electrostrictive interaction between light and phonons. Here we show that in liquids optically-induced surface deformations can provide an alternative and far stronger interaction. This allows the demonstration of ultralow threshold Brillouin lasing and strong phonon-mediated optical coupling for the first time. This form of strong coupling is a key capability for Brillouin-reconfigurable optical switches and circuits, for photonic quantum interfaces, and to generate synthetic electromagnetic fields. While applicable to liquids quite generally, our demonstration uses superfluid helium. Configured as a Brillouin gyroscope this provides the prospect of measuring superfluid circulation with unprecedented precision, and to explore the rich physics of quantum fluid dynamics, from quantized vorticity to quantum turbulence.

description: We study theoretically the magnetoresistance $ρ_{xx}(B)$ of a two-dimensional electron gas scattered by a random ensemble of impenetrable discs in the presence of a long-range correlated random potential. We believe that this model describes a high-mobility semiconductor heterostructure with a random array of antidots. We show that the interplay of scattering by the two types of disorder generates new behavior of $ρ_{xx}(B)$ which is absent for only one kind of disorder. We demonstrate that even a weak long-range disorder becomes important with increasing $B$. In particular, although $ρ_{xx}(B)$ vanishes in the limit of large $B$ when only one type of disorder is present, we show that it keeps growing with increasing $B$ in the antidot array in the presence of smooth disorder. The reversal of the behavior of $ρ_{xx}(B)$ is due to a mutual destruction of the quasiclassical localization induced by a strong magnetic field: specifically, the adiabatic localization in the long-range Gaussian disorder is washed out by the scattering on hard discs, whereas the adiabatic drift and related percolation of cyclotron orbits destroys the localization in the dilute system of hard discs. For intermediate magnetic fields in a dilute antidot array, we show the existence of a strong negative magnetoresistance, which leads to a nonmonotonic dependence of $ρ_{xx}(B)$.

description: We studied the effect of external pressure on the optical response of the nodal-line semimetal candidate ZrSiTe by reflectivity measurements. At pressures of a few GPa, the reflectivity, optical conductivity, and loss function are strongly affected in the whole measured frequency range (200-16500 cm$^{-1}$), indicating drastic changes in the electronic band structure. The pressure-induced shift of the electronic bands affects both the intraband and interband transitions. We find anomalies in the pressure dependence of several optical parameters at the pressures $P_{c1}$$\approx$4.1 GPa and $P_{c2}$$\approx$6.5 GPa, suggesting the occurrence of two phase transitions of either structural or electronic type.

description: Abstract: Electrophoretic drug delivery devices are able to deliver drugs with exceptional temporal and spatial precision. This technology has emerged as a promising platform for treating pathologies ranging from neuropathic pain to epilepsy. As the range of applications continues to expand, there is an urgent need to understand the underlying physics and estimate materials and device parameters for optimal performance. Here, computational modeling of the electrophoretic drug delivery device is carried out. Three critical performance indices, namely, the amount of drug transported, the pumping efficiency and the ON/OFF ratio are investigated as a function of initial drug concentration in the device and fixed charge concentration in the ion exchange membrane. The results provide guidelines for future materials and device design with an eye towards tailoring device performance to match disease-specific demands.

description: A recent study reported increased mortality of heads in government. To avoid the time-dependent bias (also known as immortal-time bias), survival from last election was compared between election winners and runners-up. We claim that this data manipulation results in bias due to conditioning on future events; survival should be compared from first election as well as winning should be considered as a time-dependent covariate. We collected the missing life-time periods and re-designed the study to display this bias using Lexis diagrams and multi-state methodology. We found that the bias that we termed the healthy candidate bias was even more severe than the time-dependent bias.

description: The recent discovery of a Higgs boson at the LHC, while establishing the Higgs mechanism as the way of electroweak symmetry breaking, started an era of precision measurements involving the Higgs boson. In an effective Lagrangian framework, we consider the $e^+e^-\rightarrow ZHH$ process at the ILC running at a centre of mass energy of 500 GeV to investigate the effect of the $ZZH$ and $ZZHH$ couplings on the sensitivity of $HHH$ coupling in this process. Our results show that the sensitivity of the trilinear Higgs self couplings on this process has somewhat strong dependence on the Higgs-gauge boson couplings. Single and two parameter reach of the ILC with an integrated luminosity of 1000 fb$^{-1}$ are obtained on all the effective couplings indicating how these limits are affected by the presence of anomalous $ZZH$ and $ZZHH$ couplings. The kinematic distributions studied to understand the effect of the anomalous couplings, again, show a strong influence of $Z$-$H$ couplings on the dependence of these distributions on $HHH$ coupling. Similar results are indicated in the case of the process, $e^+e^-\rightarrow ν\bar νHH$, considered at a centre of mass energy of 2 TeV, where the cross section is large enough. The effect of $WWH$ and $WWHH$ couplings on the sensitivity of $HHH$ coupling is clearly established through our analyses in this process.
