description: We present an approach to designing input devices that focuses on the structure of materials. We explore and visualize how a material reacts under manipulation, and harness the material’s properties to design new movement sensors. Two benefits spring out of this approach. One, simpler sensing emerges from making use of existing structure in the material. Two, by working with the natural structure of the material, we create input devices with readily recognizable affordances. We present six projects using this approach. We use the natural structure (coordination) of the human body to enable a mapping from five clothing-mounted accelerometers to high-quality motion capture data, creating a low-cost performance animation system. We design silicone input devices with embedded texture allowing single-camera tracking. We study squishable, conformable materials such as foam and silicone, and create a vocabulary of unit structures (shaped cuts in the material) for harnessing patterns of compression/tension to capture particular manipulations. We use this vocabulary to build soft sensing skeletons for stuffed animals, making foam cores with e-textile versions of our unit structures. We also use this vocabulary to design a tongue input device for a collaboration with Disney Imagineering. Finally, we rethink this vocabulary and apply it to capturing, using air pressure sensors, manipulations of hollow 3D-printed rubber shapes, and 3D-print several interactive robots incorporating the new vocabulary.

description: We present a scheme for correcting for crosstalk- and noise-induced errors in exchange-coupled singlet-triplet semiconductor double quantum dot qubits. While exchange coupling allows the coupling strength to be controlled independently of the intraqubit exchange couplings, there is also the problem of leakage, which must be addressed. We show that, if a large magnetic field difference is present between the two qubits, leakage is suppressed. We then develop pulse sequences that correct for crosstalk- and noise-induced errors and present parameters describing them for the 24 Clifford gates. We determine the infidelity for both the uncorrected and corrected gates as a function of the error-inducing terms and show that our corrected pulse sequences reduce the error by several orders of magnitude.

description: Electroweak Sudakov logarithms at high energy, of the form alpha/(sin^2theta_W)^n log^m s/M_{Z,W}^2, are summed using effective theory methods. The corrections are computed to processes involving two external particles in the standard model. The results include non-zero particle masses, such as the t-quark mass, electroweak mixing effects which lead to unequal W and Z masses, and radiative Higgs corrections proportional to the Yukawa couplings. We show that the matching at the scale M_{W,Z} has a term at most linear in log s/mu^2 to all orders. The effective theory formalism is compared with, and extends, previous work based on infrared evolution equations.

description: Sensing and learning channel state information 􁈺CSI􁈻 in a dynamic wireless environment 􁈺DWE􁈻 has not been a focus of the cognitive radio and network research. The focus has been on obtaining spectral resource information about the spectrum availability 􁈺i.e. spectrum sensing for dynamic spectrum access􁈻 or how to adapt radios and networks in a way that improves the effectiveness of the radio networks, for example rate adaptation. In most of these cases it is assume that the CSI is already known or it is obtained from a method that directly measures the spectrum of interest through channel estimation, fading prediction or forecasting, blind estimation, and many others. In DWEs the wireless channel may change at high rates (i.e. fast fading), and methods that directly measure the channel will not provide accurate and timely CSI needed for a cognitive radio or network. In this thesis a counterintuitive method is presented, indirect channel measurements. Indirect channel measuring is a technique used to determine the transfer function of a desired part of the RF spectrum, which spans several coherence bandwidths, without directly sending a signal through the spectrum of interest, but indirectly through adjacent spectrum. The indirect measuring of the channel has the ability to improve the timeliness and accuracy associated with the obtainment of the CSI in DWEs when using cognitive radios and networks. This thesis will explain the indirect channel measurements 􁈺ICM􁈻 research and how it can be used in cognitive radio networks for SISO rate adaptation in dynamic wireless environments. Included will be an analytical and empirical analysis of the performance of the ICM technique and other comparable and contrasting techniques. This thesis will also show which technique is best suited for a particular set of parameters for a given dynamic wireless environment. A contextual explanation will also be given to provide a visual picture of a cognitive radio network that will be able to implement the ICM technique using rate adaptation, and its ability to be implemented in hardware.

description: Crackling noise, which occurs in a wide range of situations, is characterized by discrete events of various sizes, often correlated in the form of avalanches. We report experimental evidence that the mechanical response of knitted fabric displays such broadly distributed events both in the force signal and in the deformation field, with statistics analogous to that of earthquakes or soft amorphous materials. A knit consists of a regular network of frictional contacts, linked by the elasticity of the yarn. When deformed, the fabric displays spatially extended avalanche-like yielding events resulting from collective inter-yarn contact slips. We measure the size distribution of these avalanches, at the stitch level from the analysis of non-elastic displacement fields, and externally from force fluctuations. The two measurements yield consistent power law distributions reminiscent of those found in other avalanching systems. Our study shows that a knitted fabric is not only a thread-based metamaterial with highly sought after mechanical properties, but also an original, model system, with topologically protected structural order, where intermittent, scale-invariant response emerges from minimal ingredients, and thus a significant landmark in the study of out-of-equilibrium universality.

Geometry and Integrability of Topological-Antitopological Fusion

description: Integrability of equations of topological-antitopological fusion (being proposed by Cecotti and Vafa) describing ground state metric on given 2D topological field theory (TFT) model, is proved. For massive TFT models these equations are reduced to a universal form (being independent on the given TFT model) by gauge transformations. For massive perturbations of topological conformal field theory models the separatrix solutions of the equations bounded at infinity are found by the isomonodromy deformations method. Also it is shown that ground state metric together with some part of the underlined TFT structure can be parametrized by pluriharmonic maps of the coupling space to the symmetric space of real positive definite quadratic forms.

description: The entanglement in a quantum system that possess an internal symmetry, characterized by the Sz-magnetization or U(1)-charge, is distributed among different sectors. The aim of this letter is to gain a deeper understanding of the contribution to the entanglement entropy in each of those sectors for the ground state of conformal invariant critical one dimensional systems. We find surprisingly that the entanglement entropy is equally distributed among the different magnetization sectors. Its value is given by the standard area law violating logarithmic term, that depends on the central charge c, minus a double logarithmic correction related to the zero temperature susceptibility. This result provides a new method to estimate simultaneously the central charge c and the critical exponents of U(1)-symmetric quantum chains. The method is numerically simple and gives precise results for the spin-1/2 quantum XXZ chain. We also compute the probability distribution of the magnetization in contiguous sublattices.

description: Galactic winds and fountains driven by supernova-heated gas play an integral role in re-distributing gas in galaxies, depositing metals in the circumgalactic medium (CGM), and quenching star formation. The interplay between these outflows and ram pressure stripping due to the galaxy's motion through an ambient medium may enhance these effects by converting fountain flows into expelled gas. In this paper, we present controlled, 3D simulations of ram pressure stripping combined with thermally driven, local outflows from clustered supernovae in an isolated disk galaxy modeled on the Large Magellanic Cloud (LMC), a dwarf satellite of the Milky Way on its first infall. Observational evidence of local outflows emanating from supergiant shells in the LMC and a trailing filament of HI gas originating from these regions - with no obvious Leading Arm counterpart - may represent a perfect example of this process. Our simulations present a proof-of-concept that ram pressure can convert fountain flows into expelled gas. We find that fountains launched near the peak star formation time of the LMC can comprise part of the LMC filament in the Trailing Stream, but with lower column densities than observed. Larger, more numerous outflows from the LMC may be possible and may contribute more mass, but higher inertia gas will lengthen the timescale for this gas to be swept away by ram pressure. Given the high resolution observations, increased knowledge of star formation histories, and growing evidence of multiphase, ionized outflows, the LMC is an ideal test-bed for future wind models.

Semi-Volatile Organic Compounds: Behavior and Secondary Organic Aerosol Formation

Year: 2015
Subjects: subject: 39999 Chemical Sciences not elsewhere classified
subject: FOS: Chemical sciences

description: This thesis mainly described the development of studying the behavior and secondary organic aerosol formation from semi-volatile organic compounds (SVOCs). SVOCs comprises a significant fraction of the organic mass in particulate matter (PM), which has shown important impacts on human health and also influences on Earth’s climate. SVOCs are thought to play essential roles in the formation of SOA, chemical aging and mixing processes. Smog chambers have been extensively used to study SOA formation, chemical reaction and physical properties. The interaction between SVOC vapor with Teflon chamber wall and suspended particles is a key factor influencing organic aerosol formations and behaviors in chamber experiments. We observed that pinanediol (PD) showed a large chamber wall deposition and reached a steady concentration, only around 14% of mass left in the gas phase. But we did not observe the release of PD from the chamber walls during isothermal dilution of the chamber with fresh air at 22 oC, which indicated there was no PD released from the chamber walls during the SOA formation. This clearly shows the vapor loss of SVOC precursors need to be considered when studying their SOA formation. The average carbon oxidation states the SOA from PD were calculated as around -0.7, which were similar to the value observed in CLOUD. Our data are consistent with ~10% of the SOA with low volatility that could drive new particle formation. It is challenging to measure SVOC vapor concentrations and properties. A new approach is discussed in this thesis, studying SVOC vapors from measuring the particles. The SVOCs coated particles sustained the SVOCs in the gas phase at or near their saturation concentration. The mass loss of SVOCs from the suspended particles thus reflects SVOCs vapor wall loss. Our results show the vapor wall loss rate of SVOC is consistently proportional to the SVOC vapor concentrations. We observed PEG400 seeds can sorb semi-volatile α-pinene SOA vapors. This allows us to trap semi-volatile α-pinene SOA into PEG400 seeds and then analyze their compositions and properties through measuring particles. PEG400 is liquid, water-soluble, nearly non-volatile, good solvent for SOA and relative stable during the oxidation with OH radicals and ozone. It can also be easily separated from the SOA mass spectrum with the unique fragment C4H9O2+ at m/z=89. The results demonstrated that SOA prepared from α-pinene reacted with OH produced more semi-volatile SOA vapors comparing to α-pinene ozonolysis. More semi-volatile SOA vapors were observed in the gas phase with higher SOA loadings. With well-built particle measurement methods, we may get more knowledge on the SVOC vapors.

description: In the next decade, two rovers will characterize in situ the mineralogy of rocks on Mars, using for the first time near-infrared reflectance spectrometers: SuperCam onboard the Mars 2020 rover and MicrOmega onboard the ExoMars rover, although this technique is predominantly used in orbit for mineralogical investigations. Until successful completion of sample-return missions from Mars, Martian meteorites are currently the only samples of the red planet available for study in terrestrial laboratories and comparison with in situ data. However, the current spectral database available for these samples does not represent their diversity and consists primarily of spectra acquired on finely crushed samples, albeit grain size is known to greatly affect spectral features. We measured the reflected light of a broad Martian meteorite suite as a means to catalogue and characterize their spectra between 0.4 and 3 microns. These measurements are achieved using a point spectrometer acquiring data comparable to SuperCam, and an imaging spectrometer producing hyperspectral cubes similarly to MicrOmega. Our results indicate that point spectrometry is sufficient to discriminate the different Martian meteorites families, to identify their primary petrology based on band parameters, and to detect their low content in alteration minerals. However, significant spectral mixing occurs in the point measurements, even at spot sizes down to a few millimeters, and imaging spectroscopy is needed to correctly identify the various mineral phases in the meteorites. Bidirectional spectral measurements confirm their non-Lambertian behavior, with backward and suspected forward scattering peaks. With changing observation geometry, the main absorption strengths show variations up to 10-15 percents. All the spectra presented are provided in the supplementary data for further comparison with in situ and orbital measurements.

description: Wormholes are tunnels connecting different regions in space-time. They were obtained originally as a solution for Einstein's General Relativity theory and according to this theory they need to be filled by an exotic kind of anisotropic matter. In the present sense, by "exotic matter" we mean matter that does not satisfy the energy conditions. In this article we propose the modelling of wormholes within an alternative gravity theory that proposes an extra material (rather than geometrical) term in its gravitational action. Our solutions are obtained from well-known particular cases of the wormhole metric potentials, named redshift and shape functions, and yield the wormholes to be filled by a phantom fluid, that is, a fluid with equation of state parameter $ω

description: Few studies on anti-inflammatory drugs with indole groups have been published. This is the first study that demonstrates the anti-inflammatory effects of indole derivative XCR-5a in vitro and in vivo. This study aimed to discover more anti-inflammatory drugs with indole groups and investigate their anti-inflammatory mechanisms. First, a series of indole derivatives was synthesized, then screened for XCR-5a, a compound with anti-inflammatory effects. Second, the in vitro production of IL-1β, IL-6, TNF-α, inducible nitric oxide synthase (iNOS), and cyclo-oxygenase-2 (COX-2) in lipopolysaccharide (LPS)-induced primary cells of mice pretreated with XCR-5a was determined using qPCR and ELISA. Finally, the effect of XCR-5a on LPS-induced NF-κB signaling activation was determined by Western blotting. An in vivo mouse sepsis model was established. In mouse lung tissue, the production of IL-1β, IL-6, and TNF-α was determined and H&E staining was performed. Our findings showed that XCR-5a could suppress the production of LPS-induced IL-1β, IL-6, and TNF-α, as well as mRNA expression of iNOS and COX-2. Pretreatment with XCR-5a inhibited the LPS-induced inflammatory response in septic mice in vivo by decreasing pro-inflammatory cytokines production in serum and reducing immune cell infiltration. Mechanistically, XCR-5a suppressed LPS-induced activation of the NF-κB signaling pathway. XCR-5a has anti-inflammatory effects in vitro and in vivo. Therefore, XCR-5a could be a potential drug candidate for the treatment of inflammatory diseases.

description: The original observation of the Einstein-de Haas effect was a landmark experiment in the early history of modern physics that illustrates the relationship between magnetism and angular momentum. Today the effect is still discussed in elementary physics courses to demonstrate that the angular momentum associated with the aligned electron spins in a ferromagnet can be converted to mechanical angular momentum by reversing the direction of magnetisation using an external magnetic field. In recent times, a related problem in magnetism concerns the time-scale over which this angular momentum transfer can occur. It is known experimentally for several metallic ferromagnets that intense photoexcitation leads to a drop in the magnetisation on a time scale shorter than 100 fs, a phenomenon called ultrafast demagnetisation. The microscopic mechanism for this process has been hotly debated, with one key question still unanswered: where does the angular momentum go on these sub-picosecond time scales? Here we show using femtosecond time-resolved x-ray diffraction that a large fraction of the angular momentum lost from the spin system on the laserinduced demagnetisation of ferromagnetic iron is transferred to the lattice on sub-picosecond timescales, manifesting as a transverse strain wave that propagates from the surface into the bulk. By fitting a simple model of the x-ray data to simulations and optical data, we roughly estimate that the angular momentum occurs on a time scale of 200 fs and corresponds to 80% of the angular momentum lost from the spin system. Our results show that interaction with the lattice plays an essential role in the process of ultrafast demagnetisation in this system.

description: The mechanisms behind galaxies moving away from the main sequence of star formation towards a starburst mode is one of the holy grails of galaxy evolution, with gas mass (Mgas) estimates offering a crucial insight into this critical open question. To this end, dust emission can act as one of the Mgas tracers. In this talk I will introduce a novel SED fitting technique for near-IR to (sub)mm photometry, which relies on the linear combination of a subset of pre-selected stellar, AGN and far-IR templates and show 1) how this new technique reproduces the well-established scaling relations and successfully extracts robust quantities, while at the same time being an order of magnitude faster than other available codes and 2) how these results coupled with our recent ALMA [CI] observations of distant galaxies, that allow for an alternative Mgas estimates, take us a step further into the proper characterisation of the star formation mode of the galaxies across cosmic time.

description: We suggest kinetic models of dissipation for an ensemble of interacting oriented particles, for example, moving magnetized particles. This is achieved by introducing a double bracket dissipation in kinetic equations using an oriented Poisson bracket, and employing the moment method to derive continuum equations for magnetization and density evolution. We show how our continuum equations generalize the Debye-Hueckel equations for attracting round particles, and Landau-Lifshitz-Gilbert equations for spin waves in magnetized media. We also show formation of singular solutions that are clumps of aligned particles (orientons) starting from random initial conditions. Finally, we extend our theory to the dissipative motion of self-interacting curves.

description: It has been considered that baryogenesis models without a generation of $B$-$L$ asymmetry such as the GUT baryogenesis do not work since the asymmetry is washed out by the electroweak sphalerons. Here, we point out that helical hypermagnetic fields can be generated through the chiral magnetic effect with a chiral asymmetry generated in such baryogenesis models. The helical hypermagnetic fields then produce baryon asymmetry mainly at the electroweak symmetry breaking, which remains until today. Therefore, the baryogenesis models without $B$-$L$ asymmetry can still be the origin of the present baryon asymmetry. In particular, if it can produce chiral asymmetry mainly carried by right-handed electrons of order of $10^{-3}$ in terms of the chemical potential to temperature ratio, the resultant present-day baryon asymmetry can be consistent with our Universe, although simple realizations of the GUT baryogenesis are hard to satisfy the condition. We also argue the way to overcome the difficulty in the GUT baryogenesis. The intergalactic magnetic fields with $B_0\sim 10^{-16 \sim 17}$ G and $λ_0 \sim 10^{-2\sim3}$ pc are the smoking gun of the baryogenesis scenario as discussed before.

Objective: We sought to quantify the impact of cannabis use on the risk of non-medical opioid use among people receiving pharmacotherapies for OUD. Methods: A comprehensive search was performed using multiple databases from March 1 to April 5 of 2023. Eligible studies longitudinally assessed the association between cannabis use and non-medical opioid use among people with OUD receiving treatment with buprenorphine, methadone, or naltrexone. We utilized a random-effects model employing the restricted maximum likelihood method. A sensitivity analysis was conducted to understand potential differences between each OUD treatment modality. Results: A total of 10 studies were included in the final meta-analysis. There were 8,367 participants (38% female). The average follow-up time across these studies was 9.7 months (SD = 3.77), ranging from 4 to 15 months. The pharmacotherapies involved were methadone (76.3%) buprenorphine (21.3%), and naltrexone (2.4%). The pooled odds ratio did not indicate that cannabis use significantly influenced non-medical opioid use (OR: 1.00, 95% CI: 0.97–1.04, p = .98). There is evidence of moderate heterogeneity and publication bias. Conclusion: There was no significant association between cannabis use and non-medical opioid use among patients receiving pharmacotherapies for OUD. These findings neither confirm concerns about cannabis increasing non-medical opioid use during MOUD, nor do they endorse its efficacy in decreasing non-medical opioid use with MOUD. This indicates a need for individualized approaches for cannabis use and challenges the requirement of cannabis abstinence to maintain OUD pharmacotherapies.

description: The fundamental equation of the thermodynamic system gives the relation between internal energy, entropy and volume of two adjacent equilibrium states. Taking higher dimensional charged Gauss-Bonnet black hole in de Sitter space as a thermodynamic system, the state parameters have to meet the fundamental equation of thermodynamics. We introduce the effective thermodynamic quantities to describe the black hole in de Sitter space. Considering that in the lukewarm case the temperature of the black hole horizon is equal to that of the cosmological horizon, the effective temperature of spacetime is the same, we conjecture that the effective temperature has the same value. In this way, we can obtain the entropy formula of spacetime by solving the differential equation. We find that the total entropy contain an extra terms besides the sum of the entropies of the two horizons. The corrected terms of the entropy is a function of horizon radius ratio, and is independent of the charge of the spacetime.

description: At a continuous transition into a nonunique absorbing state, particle systems may exhibit nonuniversal critical behavior, in apparent violation of hyperscaling. We propose a generalized scaling theory for dynamic critical behavior at a transition into an absorbing state, which is capable of describing exponents which vary according to the initial configuration. The resulting hyperscaling relation is supported by simulations of two lattice models.

Measuring quenching timescales by combining photometry and spectroscopy
Creators: name: Tacchella, Sandro
Publisher: name: Zenodo
Year: 2019

description: I would like to present results on quenching timescales by combining Keck DEIMOS spectroscopic data with >10-band photometry. I will discuss how one can self-consistently fit both photometric and spectroscopic data together with the tool Prospector, which allows fitting for non-parametric star-formation histories and complex stellar, nebular, and dust physics inherited from the Flexible Stellar Population Synthesis code. I show that a flexible pixel-by-pixel outlier model and an optimization step over emission line luminosities were needed to get statistically acceptable fits. These components soften the likelihood space by accounting for systematics in the models (e.g. fixed elemental abundances) and poorly characterized noise (e.g. sky lines). I will then focus on the information gained when fitting photometric and spectroscopic data together than when fitting them separately. I show that this allows determining star-formation histories and hence quenching timescales.

description: Background: Impulsive choice is associated with both cocaine use and relapse. Little is known about the influence of transient states on impulsive choice in people who use cocaine (PWUC). Objective: This study investigated the direct effects of induced boredom on impulsive choice (i.e., temporal discounting) in PWUC relative to well-matched community controls. Methods: Forty-one PWUC (≥1× cocaine use in past 3 months; 7 females) and 38 demographically matched controls (5 females) underwent two experimental conditions in counterbalanced order. Temporal discounting was assessed immediately after a standardized boredom induction task (peg-turning) and a self-selected video watched for the same duration (non-boredom). Subjective mood state and perceived task characteristics were assessed at baseline, during experimental manipulations, and after the choice task. Results: PWUC and controls were well matched on sex, age, and socioeconomic status. Groups were also similar in reported use of drugs other than cocaine, except for recent cigarette and alcohol use (PWUC > controls). As expected, peg-turning increased boredom in the sample overall, with higher boredom reported during peg-turning than the video (p < .001, η2p = .20). Participants overall exhibited greater impulsive choice after boredom than non-boredom (p = .028, η2p = .07), with no preferential effects in PWUC (p > .05, BF01 = 2.9). Conclusion: Experimentally induced boredom increased state impulsivity irrespective of cocaine use status – in PWUC and carefully matched controls – suggesting a broad link between boredom and impulsive choice. This is the first study to show that transient boredom directly increases impulsive choice. Data support a viable laboratory method to further parse the effects of boredom on impulsive choice.
A Comment on the Relationship Between Differential and Dimensional Renormalization

description: We show that there is a very simple relationship between differential and dimensional renormalization of low-order Feynman graphs in renormalizable massless quantum field theories. The beauty of the differential approach is that it achieves the same finite results as dimensional renormalization without the need to modify the space time dimension.
Clockwork without supersymmetry

description: The clockwork mechanism would be completely spoiled by the presence of a cosmological constant in the bulk of its 5D construction, or by analogous terms in the discrete case. It is believed that supersymmetry is required to forbid the appearance of these fatal terms, thus apparently tying the fate of the clockwork to the presence of supersymmetry. In this letter we argue that a robust clockwork can be obtained also without supersymmetry, by providing a model for the clockwork/linear dilaton EFT where this protection is instead related to diffeomorphism invariance in a higher number of extra dimensions. We show that the clockwork mechanism is a quite general setup that emerges, rather minimally, from pure gravity in the presence of $D-5$ additional flat extra dimensions. The linear dilaton model is obtained asymptotically in the limit of infinitely many extra dimensions. We then study the finite-$D$ theory, which is a deformation of the linear dilaton one, but still a clockwork theory for $D$ large enough.

Cosmic Variance and Its Effect on the Luminosity Function Determination in Deep High z Surveys

description: We study cosmic variance in deep high redshift surveys and its influence on the determination of the luminosity function for high redshift galaxies. For several survey geometries relevant for HST and JWST instruments, we characterize the distribution of the galaxy number counts. This is obtained by means of analytic estimates via the two point correlation function in extended Press-Schechter theory as well as by using synthetic catalogs extracted from N-body cosmological simulations of structure formation. We adopt a simple luminosity - dark halo mass relation to investigate the environment effects on the fitting of the luminosity function. We show that in addition to variations of the normalization of the luminosity function, a steepening of its slope is also expected in underdense fields, similarly to what is observed within voids in the local universe. Therefore, to avoid introducing artificial biases, caution must be taken when attempting to correct for field underdensity, such as in the case of HST UDF i-dropout sample, which exhibits a deficit of bright counts with respect to the average counts in GOODS. A public version of the cosmic variance calculator based on the two point correlation function integration is made available on the web.
