description: Broadband mid-infrared (MIR) molecular spectroscopy demands a bright and broadband light source in the molecular fingerprint region. To this end, intra-pulse difference frequency generation (IDFG) has shown excellent properties among various techniques. However, previous IDFG systems have mainly used unconventional long-wavelength 2-$μ$m ultrashort pulsed lasers. A few systems have been demonstrated with 1-$μ$m lasers, but they use bulky 100-W-class high-power Yb thin-disk lasers. In this work, we demonstrate a simple and robust approach of 1-$μ$m-pumped broadband IDFG with a conventional mode-locked Yb-doped fiber laser. We first generate 3.3-W, 12.1-fs ultrashort pulses at 50 MHz by a simple combination of spectral broadening with a short single-mode fiber and pulse compression with chirped mirrors. Then, we use them for pumping a thin orientation-patterned gallium phosphide (OP-GaP) crystal, generating 1.2-mW broadband MIR pulses with the -20-dB bandwidth of 480 cm$^{-1}$ in the fingerprint region (760-1240 cm$^{-1}$, 8.1-13.1 $μ$m). The 1-$μ$m-based IDFG system allows for simultaneous generation of ultrashort pulses in the ultraviolet and visible regions, enabling, for example, 100-MHz-level high-repetition-rate vibrational sum-frequency generation spectroscopy or pump-probe spectroscopy.

description: We present ab initio calculations of electronic and optical properties of perturbed hexagonal germanium and demonstrate that it is a superior material for active optoelectronic devices in the infrared spectral region. It is known that perfect lonsdaleite Ge is a pseudodirect semiconductor, i.e., with direct fundamental band gap but almost vanishing oscillator strength for the lowest-energy optical transitions. Perturbing the system by replacing a Ge atom in the unit cell with a Si atom boosts of the oscillator strength at the minimum direct gap by orders of magnitude, with a concurrent blue shift of the interband distances. This effect is mainly due to the increased s character of the lowest conduction band because of the perturbation-induced wave function mixing. A purely structural modification of the lonsdaleite unit cell of hexagonal Ge yields as well increased optical oscillator strengths, but their magnitude significantly depends on the actual details of the atomic geometry. In particular, moderate tensile uniaxial strain can induce an inversion of the order of the two lowest conduction bands, immediately leading to an extremely efficient enhancement of optical transitions. In general, chemical and/or structural perturbations of the lonsdaleite lattice are shown to be the key to make hexagonal germanium suitable for light emitting devices.

description: Television experiences are no longer restricted to a single audio-visual stream experienced on a single television set. Additional media activities that users engage with around a television programme are also an important experiential consideration. These activities, however, encompass a wide range of experiences and there is not a well defined set of terms in use that can adequately differentiate between them. This work considers factors that may be used to distinguish different types of experience and presents a taxonomy to provide a structured language for designers, practitioners, and researchers.

description: Super-resolution microscopy in the visible is an established powerful tool in several disciplines. In the infrared (IR) spectral range, however, no comparable schemes have been demonstrated to date. In this work, we experimentally demonstrate super-resolution microscopy in the IR range ($λ_{IR}\approx 10-12\,μ$m) using IR-visible sum-frequency generation. We operate our microscope in a wide-field scheme and image localized surface phonon polaritons in 4H-SiC nanostructures as a proof-of-concept. With this technique, we demonstrate an enhanced spatial resolution of $\simλ_{IR}/9$, enabling to resolve the polariton resonances in individual sub-diffractional nanostructures with sub-wavelength spacing. Furthermore we show, that this resolution allows to differentiate between spatial patterns associated with different polariton modes within individual nanostructures.

description: We show that a small, but \textit{measurable} shift in the eclipse mid-point time of eclipsing binary (EBs) stars of $\sim$ 0.1 seconds over a decade baseline can be used to directly measure the Galactic acceleration of stars in the Milky Way at $\sim$ kpc distances from the Sun. We consider contributions to the period drift rate from dynamical mechanisms other than the Galaxy's gravitational field, and show that the Galactic acceleration can be reliably measured using a sample of $\textit{Kepler}$ EBs with orbital and stellar parameters from the literature. Given the uncertainties on the formulation of tidal decay, our approach here is necessarily approximate, and the contribution from tidal decay is an upper limit assuming the stars are not tidally synchronized. We also use simple analytic relations to search for well-timed sources in the \textit{Kepler} field, and find $\sim$ 70 additional detached EBs with low eccentricities that have estimated timing precision better than 1 second. We illustrate the method with a prototypical, precisely timed EB using an archival \textit{Kepler} light curve and a modern synthetic \textit{HST} light curve (which provides a decade baseline). This novel method establishes a realistic possibility for obtaining fundamental Galactic parameters using eclipse timing to measure Galactic accelerations, along with other emerging new methods, including pulsar timing and extreme precision radial velocity observations. This acceleration signal grows quadratically with time. Therefore, given baselines established in the near-future for distant EBs, we can expect to measure the period drift in the future with space missions like \textit{JWST} and the \textit{Roman Space Telescope}.

description: Surrey Archaeological Collections, 65, 1-70
description: TQ 08044152. Excavations between 1956 and 1968 revealed a small but comfortable villa showing several periods of use between AD 120 and 350. There was also evidence of occupation before the villa was built, from about AD 80. The economy was based on tile-making, evidenced by quantities of debris from a tile-kiln and the likely association with the villa of the known kiln at Wykehurst, only three miles away; cattle-raising was also important, and stone from a quarry was probably sold. The dwelling house was damaged by fire in c 350 but seems already to have been abandoned. Coarse pottery, samian and small finds are catalogued and illustrated.

description: Introduction: Digital assistive technologies (e.g., applications, wearables, and robots) have emerged as promising tools for managing various aspects of daily life, such as basic assistance, encompassing social interaction, memory support, leisure activities, location tracking and health monitoring. In order to understand how these technologies can be utilized for people living with dementia, their impacts must first be reviewed. Currently, there is limited literature available on the topic, usually only focusing on a particular kind of digital assistive technology. Therefore, this paper presents a protocol for a scoping review that aims to provide a general overview of the impact digital assistive technologies can have on the quality of life for people living with dementia.
Methods and analysis: We will follow the scoping review framework proposed by Arksey and O’Malley. A comprehensive search will be performed to identify original research articles or clinical trials published between 2013 and 2023 across online databases. The review will encompass both qualitative and quantitative themes derived from the literature. Relevant studies will be identified through a comprehensive search using specific search terms related to the population (people with dementia), intervention (digital assistive technologies), and outcome (quality of life). The screening of titles, abstracts, and full texts will be performed to select eligible studies based on predetermined inclusion and exclusion criteria. Data will be extracted using a standardized form, and the findings will be synthesized and reported qualitatively and quantitatively.

description: Given the growing use of Artificial Intelligence (AI) and machine learning (ML) methods across all aspects of environmental sciences, it is imperative that we initiate a discussion about the ethical and responsible use of AI. In fact, much can be learned from other domains where AI was introduced, often with the best of intentions, yet often led to unintended societal consequences, such as hard coding racial bias in the criminal justice system or increasing economic inequality through the financial system. A common misconception is that the environmental sciences are immune to such unintended consequences when AI is being used, as most data come from observations, and AI algorithms are based on mathematical formulas, which are often seen as objective. In this article, we argue the opposite can be the case. Using specific examples, we demonstrate many ways in which the use of AI can introduce similar consequences in the environmental sciences. This article will stimulate discussion and research efforts in this direction. As a community, we should avoid repeating any foreseeable mistakes made in other domains through the introduction of AI. In fact, with proper precautions, AI can be a great tool to help {\it reduce} climate and environmental injustice. We primarily focus on weather and climate examples but the conclusions apply broadly across the environmental sciences.
Topological Lifshitz Transitions, Orbital Currents, and Interactions in Low-dimensional Fermi Gases in Synthetic Gauge Fields

description: Low-dimensional systems of interacting fermions in a synthetic gauge field have been experimentally realized using two-component ultra-cold Fermi gases in optical lattices. Using a two-leg ladder model that is relevant to these experiments, we have studied the signatures of topological Lifshitz transitions and the effects of the inter-species interaction $U$ on the gauge-invariant orbital current in the regime of large intra-leg hopping $Ω$. Focusing on non-insulating regimes, we have carried out numerically exact density-matrix renormalization-group (DMRG) calculations to compute the orbital current at fixed particle number as a function of the interaction strength and the synthetic gauge flux per plaquette. Signatures of topological Lifshitz transitions where the number Fermi points changes are found to persist even in the presence of very strong repulsive interactions. This numerical observation suggests that the orbital current can be captured by an appropriately renormalized mean-field band structure, which is also described here. Quantitative agreement between the mean-field and the DMRG results in the intermediate interaction regime where $U \lesssim Ω$ is demonstrated. We also have observed that interactions can change the sign of the current susceptibility at zero field and induce Lifshitz transitions between two metallic phases, which is also captured by the mean-field theory. Correlation effects beyond mean-field theory in the oscillations of the local inter-leg current are also reported. We argue that the observed robustness against interactions makes the orbital current a good indicator of the topological Lifshitz transitions.

The explicit characterization of counterion dynamics around a flexible polyelectrolyte

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The article presents a comprehensive study of counterion dynamics around a generic linear polyelectrolyte (PE) chain with the help of coarse-grained computer simulations. The ion-chain coupling is discussed in the form of binding time, mean-square-displacement (MSD) relative to the chain, local ion transport coefficient, and spatio-temporal correlations in the effective charge. We have shown that a counterion exhibits sub-diffusive behavior $\langle δR^2 \rangle \sim t^δ$, $δ\approx0.9$ w.r.t. chain's centre of mass (COM). The MSD of ions perpendicularly outwards from the chain segment exhibits a smaller sub-diffusive exponent compared to the one relative to the chain's COM. Further, we confirm that the effective diffusion-coefficient of counterions is strongly coupled with the chain. The effective diffusivity of ion is the lowest in chain's close proximity, extending up to length-scale of the radius of gyration Rg. Beyond Rg at larger distances, they attain diffusivity of free ion with a smooth cross-over from the adsorbed regime to the free ion regime. We have shown that the effective diffusivity drastically decreases for the higher valent ions, while the crossover length scale remains the same. Conversely, with increasing salt concentration the coupling-length scale reduces, while the diffusivity remains unaltered. The effective diffusivity of adsorbed-ion reveals an exponential reduction with electrostatic interaction strength. We further corroborate this from the binding time of ions on the chain, which also grows exponentially with the coupling strength of the ion-polymer duo. Moreover, the binding time of ions exhibits a weak dependence with salt concentration for the monovalent salt, while for higher valent salts the binding time decreases dramatically with concentration.

We then isolate a finite part of this integral, which we define as the partition function. Finally, we show how this partition function is related to a Reshetikhin-Turaev-like invariant via a reciprocity formula.

Using the recently-proposed dressing factors for the worldsheet S matrix, we formulate the string hypothesis for the mirror Bethe-Yang equations, and use it to derive the canonical mirror thermodynamic Bethe ansatz (TBA) equations of the model. For the first time, these equations account for all massive and massless modes of the model, and do not resort to any limit or special kinematics. We also discuss the simplified mirror TBA equations and the Y-system of the model.

description: Feynman integrals in quantum field theory evaluate to special functions and numbers that are usefully described by the notion of transcendental weight. In this paper, we propose a way of projecting a given dimensionally-regularised Feynman integral, for example contributing to a scattering amplitudes, onto its maximal weight part. The method uses insights into the singularity structure of space-time loop integrands, and is complementary to usual generalised unitarity approaches. We describe the method and give a proof-of-principle application to the two-loop scattering amplitudes $gg \to H$ in the heavy top-quark mass limit, which involves both planar and non-planar Feynman integrals. We also comment on further possible applications and discuss subtleties related to evanescent integrand terms.

description: The spokes of a bicycle wheel brace and stiffen its slender rim, but only as long as the pre-tension is high enough to prevent them from going slack under external loads. However, if the spoke tension is too high, the rim will buckle into a non-planar shape. Despite its importance for wheel strength and safety, we know of no formula in the literature for the maximum tension a wheel can withstand before buckling. Here we derive such a formula. The non-dimensionalized buckling tension depends only on two parameters which are identified as the ratio of rim torsional stiffness to rim bending stiffness, and the ratio of lateral spoke bracing stiffness to rim bending stiffness. The buckled rim adopts a sinusoidal lateral profile where the number of positive peaks n >= 2 is determined by these two stiffness ratios. The lateral stiffness of the wheel may be represented by a system of equivalent springs: two series-connected springs for the rim bending and torsion stiffness, connected in parallel with a spring for the spoke system.

description: We study a bi-antisymmetric tensor quantum field theory with $O(N_1)\times O(N_2)$ symmetry. Working in $4-ε$ dimensions we calculate the beta functions up to second order in the coupling constants and analyze in detail the Renormalization Group (RG) flow and its fixed points. We allow $N_1$ and $N_2$ to assume general real values and treat them as bifurcation parameters. In studying the behavior of the model in the space of $N_1$ and $N_2$ we find a point where a zero-Hopf bifurcation occurs. In the vicinity of this point, we provide analytical and numerical evidence for the existence of Shilnikov homoclinic orbits, which induce chaotic behavior in the RG flow of the model. As a simple warm-up example for the study of chaotic RG flows, we also review the non-hermitian Ising chain and show how for special complex values of the coupling constant, its RG transformations are chaotic and equivalent to the Bernoulli map.

description: Since its beginnings, fission theory has asumed that low-energy induced fission takes place through transition-state channels at the barrier tops. Neverthess, up to now there is no microscopic theory applicable to those conditions. We suggest that modern reaction theory is suitable for this purpose, and propose a methodology based on a configuration-interaction framework using the Generator Coordinate Method (GCM). Simple reaction-theoretic models are constructed with the Gaussian Overlap Approximation (GOA) to parameterize both the dynamics within the channels and their incoherent couplings to states outside the barrier. The physical characteristics of the channels examined here are their effective bandwidths and the quality of the coupling to compound-nucleus states as measured by the transmission factor $T$. We also investigate the spacing of GCM states with respect to their degree of overlap. We find that a rather coarse mesh provides an acceptable accuracy for estimating the bandwidths and transmission factors. The common numerical stability problem in using the GCM is avoided due to the choice of meshes and the finite bandwidths of the channels. The bandwidths of the channels are largely controlled by the zero-point energy with respect to the collective coordinate in the GCM configurations.

description: Most tropical insectivorous birds, unlike their temperate counterparts, hold and defend a feeding and breeding territory year-around. However, our understanding of ecological factors influencing territory selection and size in tropical insectivores is limited. Here we examine three prominent hypotheses relating food abundance, food dispersion (spatial arrangement of food items), and habitat structure to territoriality in the Usambara Thrush Turdus roehli. We first compared leaf-litter macro-invertebrate abundance and dispersion, and habitat structure between territories and random sites. We then examined the relation between these same ecological factors and territory size. Invertebrate abundance and dispersion were sparsely and evenly distributed across our study system and did not vary between territories and random sites. In contrast, habitat structure did vary between territories and random sites indicating the Usambara Thrush selects territories with open understorey and closed overstorey habitat. Invertebrate abundance and dispersion within territories of the Usambara Thrush were not associated with habitat structure. We believe the most likely explanation for the Usambara Thrush’s preference for open understorey and closed overstorey habitat relates to foraging behavior. Using information-theoretic model selection we found that invertebrate abundance was the highest-ranked predictor of territory size and was inversely related, consistent with food value theory of territoriality.

description: A protocol for generating Greenberger-Horne-Zeilinger states in a system of $N$ coupled qubits is proposed. The Hamiltonian model assumes $N$-wise interactions between the $N$ qubits and the presence of a controllable time-dependent field acting upon one spin only. Implementing such a scenario is in the experimental reach. The dynamical problem is exactly solved thanks to the symmetries of the Hamiltonian model. The possibility of generating GHZ states under both adiabatic and non-adiabatic conditions is shown and discussed in detail.

description: Spectroscopic studies of aluminum monofluoride (AlF) have revealed its highly favorable properties for direct laser cooling. All $Q$ lines of the strong A$^1Π$ $\leftarrow$ X$^1Σ^+$ transition around 227~nm are rotationally closed and thereby suitable for the main cooling cycle. The same holds for the narrow, spin-forbidden a$^3Π$ $\leftarrow$ X$^1Σ^+$ transition around 367 nm which has a recoil limit in the micro Kelvin range. We here report on the spectroscopic characterization of the lowest rotational levels in the a$^3Π$ state of AlF for $v=0-8$ using a jet-cooled, pulsed molecular beam. An accidental AC Stark shift is observed on the a$^3Π_0, v=4$ $\leftarrow$ X$^1Σ^+, v=4$ band. By using time-delayed ionization for state-selective detection of the molecules in the metastable a$^3Π$ state at different points along the molecular beam, the radiative lifetime of the a$^3Π_1, v=0, J=1$ level is experimentally determined as $τ=1.89 \pm 0.15$~ms. A laser/radio-frequency multiple resonance ionization scheme is employed to determine the hyperfine splittings in the a$^3Π_1, v=5$ level. The experimentally derived hyperfine parameters are compared to the outcome of quantum chemistry calculations. A spectral line with a width of 1.27 kHz is recorded between hyperfine levels in the a$^3Π, v=0$ state. These measurements benchmark the electronic potential of the a$^3Π$ state and yield accurate values for the photon scattering rate and for the elements of the Franck-Condon matrix of the a$^3Π$ $-$ X$^1Σ^+$ system.

Year: 2024

description: This dissertation consists of three essays. It connects the overarching theme of the Adaptive Market Hypothesis and Market Microstructure in term of information diffusion and decision making related to stock market dynamics. By scrutinizing the behavioral emergent phenomena, this dissertation offers novel insights on how the information gets disseminated into the market, and how heterogeneous and bounded rational agents extract information and make trading decisions in a dynamic and uncertain environment, along with a nuanced understanding of how behavioral heuristics, cognitive and emotional biases, learning, and social interactions affect the dynamics and efficiency of financial markets. •Essay 1: Does The Stock Market Punish Corporate Malfeasance? A Case Study of Citigroup·This paper examines how well the market anticipates regulatory sanction. We look at key dates of SEC, NASD, FTC, Congressional and foreign investigations and their subsequent resolution. Our event study confirms that the settlements provide little new information to the market. In six major case groupings, we find highly accurate predictions from market capitalization changes of settlements and associated private litigation. •Essay 2: Experts Online: An Analysis of Trading Activity in a Public Internet Chat Room·We analyze the trading activity in an Internet chat room over a four-year period. The dataset contains nearly 9,000 trades from 676 traders. We found these traders are more skilled than retail investors analyzed in other studies. 55% make profits after transaction costs, and they have statistically significant α’s of 0.17% per day after controlling for the Fama-French factors and momentum. Traders hold their winners 25% longer than their losers. 42% trade both long and short, with equal success rates, and almost double the profit per trade when short. The estimates show a strong influence from other traders, with a buy (sell) order 40.7% more likely to be of the same sign if there has been a recent post. Traders improve their skill over time, earning an extra $189 per month for each year of trading experience. They also gain expertise in trading particular stocks. Traders who raise their Herfindahl index by 0.1 raise their profitability by $46 per trade.•Essay 3: Highs and Lows: A Behavioral and Technical AnalysisThe paper investigates the relationship between trading volume (turnover) and n-day highs and lows in stock prices to understand traders' reliance on these signals. We find that turnover rises on n-day highs and lows and is an increasing function of n. We offer several explanations from the technical and behavioral finance literature for why traders might use these signals. Turnover is persistent following these events, and new lows provide abnormal returns for up to 6 trading days.

description: Measurements of bicycle kinematics (roll and steer) and rider movements (joint angles and rider lean) typically require a purpose-built instrumented bicycle and/or a motion capture laboratory, which make it difficult or impossible to take measurements during real-world cycling (unconstrained riding outside of a laboratory). In this paper, I present an approach for using an array of 11 wireless inertial sensors to measure the kinematics of a bicycle and rider that can be quickly and easily configured to any rider-bicycle system. A series of simple alignment movements is used to align the sensors to the rider and bicycle, which enables calculations of bicycle speed, roll rate and angle, steer rate and angle, and yaw rate as well as the rider’s ankle, knee, and torso lean angles. Other than the wheel radius of the bicycle, no additional measurements of the subject or bicycle are required for the calculations. To demonstrate the utility of my approach, I used the system to measure the rider-bicycle kinematics of a subject riding his bicycle during a one hour ride through a variety of terrain, including paved roads, dirt roads, and off-road mountain biking trails. The dataset highlights the effect of terrain on steer and rider lean, provides insights into rider strategy and technique, and confirms that an array of wireless inertial sensors can provide measurements of bicycle and rider kinematics. My approach enables meaningful data to be collected in real-world environments to explore how bicycle design, rider preferences, rider ability, terrain, and environment affect bicycle and rider behaviour, performance, and control strategies.

description: We present a recently developed terahertz platform. An air plasma produced by an ultrashort two-color laser pulse serves as a broadband terahertz source, with electric field that has peak amplitude in the MV/cm range. Air biased coherent detection of the terahertz field is employed where a peak detector associated with a micro-controller board acquires the signal coming from an avalanche photodiode. The temporal and spectral profiles of the produced terahertz electric field are presented, in excellent agreement with numerical simulations of the whole setup. We illustrate the capabilities of this platform by performing spectroscopy on water vapor and of a polystyrene reference sample.

description: Exposure of Arabidopsis leaves to nitrogen dioxide (NO2) results in nitration of specific chloroplast proteins. To determine whether NO2 itself and/or nitrite derived from NO2 can nitrate proteins, Arabidopsis thylakoid membranes were isolated and treated with NO2-bubbled or potassium nitrite (KNO2) buffer, followed by protein extraction, electrophoresis, and immunoblotting using an anti-3-nitrotyrosine (NT) antibody. NO2 concentrations in the NO2-bubbled buffer were calculated by numerically solving NO2 dissociation kinetic equations. The two buffers were adjusted to have identical nitrite concentrations. Both treatments yielded an NT-immunopositive band that LC/MS identified as PSBO1. The difference in the band intensity between the 2 treatments was designated nitration by NO2. Both NO2 and nitrite mediated nitration of proteins, and the nitration ability per unit NO2 concentration was ∼100-fold greater than that of nitrite.
Potential costs and benefits of a right-to-charge policy: an example for Switzerland

description: Electric vehicles (EVs) are essential to decarbonize individual mobility and their adoption is highly dependent on the possibility of charging at home. However, tenants in multi-family apartment buildings face legal and financial barriers to the installation of home-charging. Through this study for Switzerland, we make the case of the economic benefits of a policy overcoming these barriers. Through an extrapolation of the EV diffusions towards 2035, we show that the benefits of switching towards EVs are overwhelming positive for its users and for society in general. The acceleration of EV adoption through a right-to-charge policy can potentially benefit the Swiss population by about 12 billion USD, corresponding to about 1.5 percent of GDP. Failing to implement an easy access to home charging-infrastructure in a timely manner will results in a considerable loss for the Swiss economy, eventually at the costs of citizens and the climate.

description: A satisfação com a vida é considerada como um dos principais indicadores de bem-estar subjetivo, sendo avaliada como uma medida geral ou como referência a áreas importantes da vida, a exemplo do trabalho e da família. Avaliar a satisfação com a vida dos portadores de necessidades especiais e verificar se este construto se correlaciona ou varia em função de variáveis demográficas (sexo, idade, escolaridade), foi o objetivo do presente estudo. A coleta de dados englobou um questionário com caracterização dos sujeitos, dados sobre a deficiência, medida de Satisfação com a vida de Ed Diener (Satisfaction With Life Scale), uma escala de 7 pontos, variando de 1 (discordo totalmente) a 7 (concordo totalmente)  e, a perguntas visando uma avaliação do impacto da necessidade especial na sua vida. Responderam ao questionário 48 pessoas residentes em Juazeiro do Norte-CE, com idades variando entre 14 e 71 anos, de ambos os sexos, sendo a maioria do sexo masculino (60,4%). Os resultados demonstraram que em 70,9% dos entrevistados acreditam que na maioria dos aspectos, sua vida é próxima do ideal e que, 72,9% dos sujeitos concordam que estão satisfeitos com a sua vida, da maneira como ela é e, 41,7% dos entrevistados afirmaram que as condições de suas vidas são excelentes. Quanto ao Gênero, os homens se mostraram mais satisfeitos com a vida que as mulheres, bem como as pessoas mais religiosas e as pessoas mais velhas. Conclusão: O estudo demonstrou que o impacto da perda de algumas capacidades provocada pela necessidade especial, não parece ter implicado em grandes mudanças emocionais, em termos de satisfação com a vida na população estudada.
