description: Entrainment is the propensity of speakers to begin behaving like one another in conversation. We identify evidence of entrainment in a number of acoustic and prosodic dimensions in conversational speech of Standard American English speakers and Mandarin Chinese speakers. We compare entrainment in the Columbia Games Corpus and the Tongji Games Corpus and find similar patterns of global and local entrainment in both. Differences appear primarily in global convergence.
Entanglement properties of random invariant quantum states

description: Entanglement properties of random multipartite quantum states which are invariant under global SU($d$) action are investigated. The random states live in the tensor power of an irreducible representation of SU($d$). We calculate and analyze the expectation and fluctuation of the second-order Rényi entanglement measure of the random invariant and near-invariant states in high dimension, and reveal the phenomenon of concentration of measure the random states exhibit. We show that with high probability a random SU($d$)-invariant state is close to being maximally entangled with respect to any bipartite cut as the dimension of individual system goes to infinity. We also show that this generic entanglement property of random SU(2)-invariant state is robust to arbitrarily finite disturbation.

description: We investigate some peculiar aspects of the so called Lee-Wick Electrodynamics focusing on physical effects produced by the presence of sources for the vector field. The interactions between stationary charges distributions along parallel branes with arbitrary dimensions is investigated and the energy of a point charge is discussed. Some physical phenomena produced in the vicinity of a Dirac string are also investigated. We consider the Lee-Wick theory for the scalar field, where it can emerge some interesting effects with no counterpart for the vector gauge field theory.

description: Conflicts of interest over resources or reproduction among individuals in a social group have long been considered to result in automatic and universal costs to group living. However, exploring how social conflict varies with group size has produced mixed empirical results. Here we develop a model that generates alternative predictions for how social conflict should vary with group size depending on the type of benefits gained from being in a social group. We show that a positive relationship between social conflict and group size is favored when groups form primarily for the benefits of sociality but not when groups form mainly for accessing group-defended resources. Thus, increased social conflict in animal societies should not be viewed as an automatic cost of larger social groups. Instead, studying the relationship between social conflict and the types of grouping benefits will be crucial for understanding the evolution of complex societies.

description: Polarisation Filter Array (PFA) cameras allow the analysis of light polarisation state in a simple and cost-effective manner. Such filter arrays work as the Bayer pattern for colour cameras, sharing similar advantages and drawbacks. Among the others, the raw image must be demosaiced considering the local variations of the PFA and the characteristics of the imaged scene. Non-linear effects, like the cross-talk among neighbouring pixels, are difficult to explicitly model and suggest the potential advantage of a data-driven learning approach. However, the PFA cannot be removed from the sensor, making it difficult to acquire the ground-truth polarization state for training. In this work we propose a novel CNN-based model which directly demosaics the raw camera image to a per-pixel Stokes vector. Our contribution is twofold. First, we propose a network architecture composed by a sequence of Mosaiced Convolutions operating coherently with the local arrangement of the different filters. Second, we introduce a new method, employing a consumer LCD screen, to effectively acquire real-world data for training. The process is designed to be invariant by monitor gamma and external lighting conditions. We extensively compared our method against algorithmic and learning-based demosaicing techniques, obtaining a consistently lower error especially in terms of polarisation angle.

description: Background: Cigarette smoke yields of tar and nicotine obtained under the Federal Trade Commission (FTC)-specified machine-smoking protocol (35-mL puff volume drawn for 2 seconds once per minute) may not accurately reflect the delivery of toxins and carcinogens to the smoker. We conducted this study to obtain more realistic estimates of exposure to components of cigarette smoke that affect lung cancer risk.

Methods: We used a pressure transducer system to evaluate puffing characteristics for 133 smokers of cigarettes rated by the FTC at 1.2 mg of nicotine or less (56 smokers of low-yield cigarettes [less than 0.8 mg of nicotine per cigarette] and 77 smokers of medium-yield cigarettes [0.9–1.2 mg of nicotine per cigarette]). We programmed measurements from a randomly chosen subset of 72 of these smokers into a piston-type machine to generate smoke from each smoker’s usual brand of cigarettes for assays of nicotine, carbon monoxide, tar, and the lung cancer-causing agents 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and benzo[a]pyrene. The FTC protocol was also used to assess levels of targeted components in the 11 brands most frequently smoked by study subjects.

Results: Compared with the FTC protocol values, smokers of low- and medium-yield brands took in statistically significantly larger puffs (48.6 and 44.1 mL, respectively) at statistically significantly shorter intervals (21.3 and 18.5 seconds, respectively), and they drew larger total smoke volumes than specified in the FTC parameters. They received, respectively, 2.5 and 2.2 times more nicotine and 2.6 and 1.9 times more tar than FTC-derived amounts, as well as about twofold higher levels of benzo[a]-pyrene and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone. Smokers of medium-yield cigarettes compared with smokers of low-yield cigarettes received higher doses of all components.

Conclusions: The FTC protocol underestimates nicotine and carcinogen doses to smokers and overestimates the proportional benefit of low-yield cigarettes. Thus, FTC-based nicotine medication doses prescribed/recommended for smoking cessation may need to be reassessed.

description: Monoclonal antibodies (mAbs) are becoming increasingly important as biopharmaceutical product. The high specific affinity of mAbs is successfully used for the therapy of numerous severe diseases, such as autoimmune diseases, infections and many types of cancer. In order to be used as a drug, mAbs must be processed after biotechnological production by animal cell cultivation. For the benefit of patient safety, high quality and purity criteria apply, which must be met at the end of the manufacturing process. Due to the steadily increasing demand, in combination with improvements in the cell cultivation over the last decades, existing facilities and conventional purification methods are reaching their capacity limits. To meet these challenges, new, alternative methods such as aqueous two-phase extraction (ATPE) move into the focus of research. In the first part of this PhD thesis, the composition of the aqueous two-phase system (ATPS) was optimized with respect to yield and purity of the used mAb by means of a Design of Experiments (DoE) approach. Subsequently, a new methodology was developed to separate the mAb-containing product phase of the ATPS from the impurity-containing phase using a membrane-based approach. Thus, the clarification with the capture and first purification of the mAb was successfully integrated in one unit operation. In the second part of the thesis the integration of the ATPE into the subsequent downstream process was investigated. After optimization of the individual unit operations, the entire mAb production process based on ATPE was successfully executed with high yield, purity and constant product quality of the mAb. In the third part of the PhD thesis, the proof of concept for the application of ATPE to high cell density (HCD) processes was investigated, which allow process intensification and increased productivity of the mAb manufacturing. The influence of cell density was investigated using different ATPS. Clarification as well as mAb capture and purification were obtained for HCD cultivation. Thus the results of this work contribute to overcome existing bottlenecks in the production of mAbs, as important biopharmaceutical products.

description: We present a new approach to long range coupling based on a combination of adiabatic passage and lateral leakage in thin shallow ridge waveguides on a silicon photonic platform. The approach enables transport of light between two isolated waveguides through a mode of the silicon slab that acts as an optical bus. Due to the nature of the adiabatic protocol, the bus mode has minimal population and the transport is highly robust. We prove the concept and examine the robustness of this approach using rigorous modelling. We further demonstrate the utility of the approach by coupling power between two waveguides whilst bypassing an intermediate waveguide. This concept could form the basis of a new interconnect technology for silicon integrated photonic chips.

description: We investigate the effects of finite baryon chemical potential on the transport properties of a hadron resonance gas. We find that a hadron resonance gas with large baryon number density is closer to the ideal fluid limit than the corresponding gas with zero baryon number. This suggests that the system created at the Relativistic Heavy Ion Collider (RHIC) at lower collision energies may behave as a fluid, with an effective fluidity close to the one found at RHIC's highest energy near phase transition. This might explain why the differential elliptic flow coefficient measured at lower collisional energies at RHIC is similar to the one observed at high energies.

description: We present near-infrared ($H$- and $K$-band) integral-field observations of the inner $\sim$700pc of the active spiral galaxy NGC613, obtained with SINFONI on the Very Large Telescope. We use emission-line ratios to determine the dominant excitation mechanisms in different regions within our field-of-view, in particular the active nucleus and the star-forming circum-nuclear ring. Diagnostic diagrams involving [FeII] and H$_2$ fluxes indicate that the gas is not only photoionized by the AGN in the nucleus of NGC613, but also shock-heated. On the other hand, the emission line ratios measured in the ``hot spots'' along the ring are fully consistent with them being young star forming regions. We find no sign of radial gas transport from the ring into the core region dominated by the AGN. The ring morphology appears disturbed by a radial outflow of material from the AGN, which is confirmed by the existence of a weak jet in archival radio maps. However, this jet does not seem to have any significant effect on the morphology of the large ($\sim$8$\times$10$^7$ solar masses) reservoir of molecular gas that has accumulated inside the central $\sim$100pc. Such a concentration of molecular gas around an AGN is unusual, and supports a scenario in which star formation is recurrent and episodic in spiral galaxies. In this context, NGC613 appears to be in final stages of the gas accumulation phase, and is likely to undergo a nuclear starburst in the near future.

description: Objectives. We assessed associations between new-onset (post–September 11, 2001 [9/11]) lower respiratory symptoms reported on 2 surveys, administered 3 years apart, and acute and chronic 9/11-related exposures among New York City World Trade Center–area residents and workers enrolled in the World Trade Center Health Registry.

Methods. World Trade Center–area residents and workers were categorized as case participants or control participants on the basis of lower respiratory symptoms reported in surveys administered 2 to 3 and 5 to 6 years after 9/11. We created composite exposure scales after principal components analyses of detailed exposure histories obtained during face-to-face interviews. We used multivariate logistic regression models to determine associations between lower respiratory symptoms and composite exposure scales.

Results. Both acute and chronic exposures to the events of 9/11 were independently associated, often in a dose-dependent manner, with lower respiratory symptoms among individuals who lived and worked in the area of the World Trade Center.

Conclusions. Study findings argue for detailed assessments of exposure during and after events in the future from which potentially toxic materials may be released and for rapid interventions to minimize exposures and screen for potential adverse health effects.

description: Introduction
Evacuation of the World Trade Center (WTC) twin towers and surrounding buildings damaged in the September 11, 2001 attacks provides a unique opportunity to study factors that affect emergency evacuation of high rise buildings.

Problem
The goal of this study is to understand the extent to which structural and behavioral barriers and limitations of personal mobility affected evacuation by occupants of affected buildings on September 11, 2001.

Methods
This analysis included 5,023 civilian, adult enrollees within the World Trade Center Health Registry who evacuated the two World Trade Center towers and over 30 other Lower Manhattan buildings that were damaged or destroyed on September 11, 2001. Multinomial logistic regression was used to predict total evacuation time (less than 30 to ≤60 minutes, greater than 1 hour to less than 2 hours relative to ≤30 minutes) in relation to number of infrastructure barriers and number of behavioral barriers, adjusted for demographic and other factors.

Results
A higher percentage of evacuees reported encountering at least one behavioral barrier (84.9%) than reported at least one infrastructure barrier (51.9%). This pattern was consistent in all buildings except WTC 1, the first building attacked, where greater than 90% of evacuees reported encountering both types of barriers. Smoke and poor lighting were the most frequently-reported structural barriers. Extreme crowding, lack of communication with officials, and being surrounded by panicked crowds were the most frequently-reported behavioral barriers. Multivariate analyses showed evacuation time to be independently associated with the number of each type of barrier as well as gender (longer times for women), but not with the floor from which evacuation began. After adjustment, personal mobility impairment was not associated with increased evacuation time.

Conclusion
Because most high-rise buildings have unique designs, infrastructure factors tend to be less predictable than behavioral factors, but both need to be considered in developing emergency evacuation plans in order to decrease evacuation time and, consequently, risk of injury and death during an emergency evacuation.

description: We present results of recurrence analysis of 46 active galactic nuclei (AGN) using light curves from the 157-month catalog of the Swift Burst Alert Telescope (BAT) in the 14-150 keV band. We generate recurrence plots and compute recurrence plot metrics for each object. We use the surrogate data method to compare all derived recurrence-based quantities to three sets of stochastic light curves with identical power spectrum, flux distribution, or both, in order to determine the presence of determinism, non-linearity, entropy, and non-stationarity. We compare these quantities with known physical characteristics of each system, such as black hole mass, Eddington ratio, and bolometric luminosity, radio loudness, obscuration, and spectroscopic type. We find that almost all AGN in this sample exhibit substantial higher-order modes of variability than is contained in the power spectrum, with approximately half exhibiting nonlinear or non-stationary behavior. We find that Type 2 AGN are more likely to contain deterministic variability than Type 1 AGN while the same distinction is not found between obscured and unobscured AGN. The complexity of variability among Type 1 AGN is anticorrelated with Eddington ratio, while no relationship is found among Type 2 AGN. The connections between the recurrence properties and AGN class suggest that hard X-ray emission is a probe of distinct accretion processes among classes of AGN, which supports interpretations of changing-look AGN and challenges the traditional unification model that classifies AGN only on viewing angle.

Universal power law in crossover from integrability to quantum chaos

description: We study models of interacting fermions in one dimension to investigate the crossover from integrability to non-integrability, i.e., quantum chaos, as a function of system size. Using exact diagonalization of finite-sized systems, we study this crossover by obtaining the energy level statistics and Drude weight associated with transport. Our results reinforce the idea that for system size $L \to \infty$ non-integrability sets in for an arbitrarily small integrability-breaking perturbation. The crossover value of the perturbation scales as a power law $\sim L^{-3}$ when the integrable system is gapless and the scaling appears to be robust to microscopic details and the precise form of the perturbation. We conjecture that the exponent in the power law is characteristic of the random matrix ensemble describing the non-integrable system. For systems with a gap, the crossover scaling appears to be faster than a power law.

description: Purpose
Cigarette smoking is the major cause of laryngeal cancer. The time to first cigarette after waking in the morning is a behavior associated with several dimensions of nicotine dependence including the dose of smoke uptake. We hypothesized that a short TTFC increases the risk of laryngeal cancer.

Methods
The analysis was based on data from a hospital-based case–control study of laryngeal cancer. The current analysis included only subjects who were ever cigarette smokers, including 570 cases and 343 controls (832 whites and 81 blacks). Odds ratios (OR) and 95% confidence intervals (CI) were calculated using unconditional logistic regression adjusting for smoking history and other potential confounders. Incidence data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute from 1975 to 2006 were analyzed for trends in laryngeal cancer.

Results
There was a dose–response relationship between TTFC and supraglottic cancer. Compared to subjects who smoked more than 60 min after waking, the adjusted odds ratio was 1.51 (95% CI, 0.63–3.61) for 30–60 min and 3.13 (95% CI, 1.56–6.30) for 0–30 min. No association was observed between TTFC and cancer of the glottis. In blacks, the TTFC was not associated with the risk of laryngeal cancer. Trends in SEER rates were similar for cancer of the glottis and supraglottis, indicating that the site-specific differences were not affected by unknown confounders.

Conclusion
A nicotine dependence behavior that is associated with cigarette smoke uptake increases the risk of cancer of the supraglottis larynx, but not glottis larynx.

Publisher: name: Zenodo
Year: 2023

description: This research paper offers an in-depth examination of parole decision-making processes through a comparative study involving India and multiple Commonwealth nations. Parole systems play a pivotal role in the criminal justice landscape, balancing the objectives of offender rehabilitation, community safety, and adherence to human rights principles. This study sheds light on the complex dynamics within parole systems, drawing valuable insights from diverse jurisdictions.
 
The comparative analysis reveals a spectrum of parole systems, showcasing variations in eligibility criteria, assessment methods, and the role of the judiciary in decision-making. It underscores the importance of balancing the dual goals of rehabilitation and public safety, emphasizing that effective parole systems contribute significantly to reducing recidivism rates and fostering offender reintegration.
 
A key focal point of this study is the centrality of human rights principles within parole systems. Both India and the Commonwealth nations emphasize the right to rehabilitation and a fair trial. This emphasis aligns with international human rights standards, highlighting the critical need to ensure that parole systems respect and uphold these rights.
 
The integration of restorative justice principles within some Commonwealth nations' parole systems represents an innovative approach to offender rehabilitation and community reintegration. This dimension of the study contributes to the ongoing global discourse on restorative justice and its potential benefits in criminal justice contexts.
 
Moreover, the research emphasizes the importance of data-driven decision-making, advocating for centralized data collection and analysis to support evidence-based policy in parole systems. It calls for tailored programs and support services to meet the unique needs of vulnerable populations, such as Indigenous communities and individuals with mental health issues.
 
This study offers a comprehensive overview of the parole landscape, providing valuable policy and legal recommendations. These recommendations advocate for standardized guidelines, transparent victim impact statements, public awareness campaigns, and international collaboration as essential components of effective parole systems.
 
This research contributes significantly to the global discourse on parole systems, rehabilitation, human rights, restorative justice, and data-driven policy. By drawing on the experiences of India and Commonwealth nations, it offers a holistic understanding of the challenges and opportunities within parole systems, paving the way for evidence-based reforms and advancements in the field.

description: The 2-rank of a compact Lie group $G$ is the maximal possible rank of the elementary 2-subgroup ${\mathbb Z}_{2}\times... {\mathbb Z}_{2}$ of $G$. The study of 2-ranks (and $p$-rank for any prime $p$) of compact Lie groups was initiated in 1953 by A. Borel and J.-P. Serre. Since then the 2-ranks of compact Lie groups have been investigated by many mathematician. The 2-ranks of compact Lie groups relate closely with several important areas in mathematics. In this article, we survey important results concerning 2-ranks of compact Lie groups. In particular, we present the complete determination of 2-ranks of compact connected simple Lie groups $G$ via the 2-numbers introduced by B. Y. Chen and T. Nagano in [Un invariant gémétrique riemannien, C. R. Acad. Sci. Paris, 295 (1982), 389--391] and [A Riemannian geometric invariant and its applications to a problem of Borel and Serre, Trans. Amer. Math. Soc. 308 (1988), 273--297].

Realizability of Iso-$g_2$ Processes via Effective Pair Interactions

description: An outstanding problem in statistical mechanics is the determination of whether prescribed functional forms of the pair correlation function $g_2(r)$ [or equivalently, structure factor $S(k)$] at some number density $ρ$ can be achieved by $d$-dimensional many-body systems. The Zhang-Torquato conjecture states that any realizable set of pair statistics, whether from a nonequilibrium or equilibrium system, can be achieved by equilibrium systems involving up to two-body interactions. In light of this conjecture, we study the realizability problem of the nonequilibrium iso-$g_2$ process, i.e., the determination of density-dependent effective potentials that yield equilibrium states in which $g_2$ remains invariant for a positive range of densities. Using a precise inverse methodology that determines effective potentials that match hypothesized functional forms of $g_2(r)$ for all $r$ and $S(k)$ for all $k$, we show that the unit-step function $g_2$, which is the zero-density limit of the hard-sphere potential, is remarkably numerically realizable up to the packing fraction $ϕ=0.49$ for $d=1$. For $d=2$ and 3, it is realizable up to the maximum ``terminal'' packing fraction $ϕ_c=1/2^d$, at which the systems are hyperuniform, implying that the explicitly known necessary conditions for realizability are sufficient up through $ϕ_c$. For $ϕ$ near but below $ϕ_c$, the large-$r$ behaviors of the effective potentials are given exactly by the functional forms $\exp[-κ(ϕ) r]$ for $d=1$, $r^{-1/2}\exp[-κ(ϕ) r]$ for $d=2$, and $r^{-1}\exp[-κ(ϕ) r]$ (Yukawa form) for $d=3$, where $κ^{-1}(ϕ)$ is a screening length, and for $ϕ=ϕ_c$, the potentials at large $r$ are given by the pure Coulomb forms in the respective dimensions, as predicted by Torquato and Stillinger [\textit{Phys. Rev. E}, 68, 041113 1-25 (2003)].

description: The advent of quantum optical techniques based on superconducting circuits has opened new regimes in the study of the non-linear interaction of light with matter. Of particular interest has been the creation of non-classical states of light, which are essential for continuous-variable quantum information processing, and could enable quantum-enhanced measurement sensitivity. Here we demonstrate a device consisting of a superconducting artificial atom, the Cooper pair transistor, embedded in a superconducting microwave cavity that may offer a path toward simple, continual production of non-classical photons. By applying a dc voltage to the atom, we use the ac Josephson effect to inject photons into the cavity. The backaction of the photons on single-Cooper-pair tunneling events results in a new regime of simultaneous quantum coherent transport of Cooper pairs and microwave photons. This single-pair Josephson laser offers great potential for the production of amplitude-squeezed photon states and a rich environment for the study of the quantum dynamics of nonlinear systems.

DEEP LEARNING APPROACHES FOR AUTOMATIC ACOUSTIC DETECTION OF THE BACHMAN'S SPARROW AND ITS APPLICATION TO ASSESSING ITS RESPONSE TO PRESCRIBED BURNS IN SUBTROPICAL HABITATS OF CENTRAL FLORIDA

description: Passive acoustic monitoring (PAM) is a tool with immense potential to evaluate the response of wildlife to ecosystem disturbances. PAM allows to evaluate wildlife dynamics by means of acoustic indices that estimate the diversity or complexity of sounds in a recording, as well as to study ecological aspects at the species level by training machine learning-based automatic acoustic detector. In this study, five deep learning approaches for automatic song detection were evaluated of the near-threatened Bachman's Sparrow in data scarcity scenarios, and then used this classifier to study the response of this bird to the number of days following a prescribed burn in six subtropical habitats in central Florida. At the same time, the response of avifauna acoustic activity to prescribed burning was quantified by means of three of the most used acoustic indices used in the literature (Acoustic Complexity Index, Acoustic Diversity Index and Bioacoustic Index). I found that it is possible to construct competitive birdsong detectors with small datasets using pre-trained models regardless. Furthermore, the use of data augmentation can lead to a detriment of the detector performance, especially of lower quality recordings, and that increasing the dataset does not necessarily increase the generalizability of the model. On the other hand, I found that unlike Acoustic Diversity Index, the Bioacoustic and Acoustic Complexity indices are negatively correlated with time after a burn, the same trend that Bachman's Sparrow presence showed, even though it was more influenced by habitat type than by the effect of the prescribed burns. This study shows the potential of tools including automatic song detection and acoustic indices to model at different scales the dynamics of avifauna in response to ecosystem disturbances. Their development can provide efficient tools for the study and conservation of both threatened wildlife species and the ecosystems they inhabit.

For this scenario we consider an charged AdS$_{4}$ black hole for an Einstein-Maxwell model where the derivative quadrivector is replaced by a deformed version inspired in Kaniadakis statistics. Besides, we extract the transport coefficient know as electrical conductivity.

description: We show that all finite-dimensional resolvable generalized manifolds with the piecewise disjoint arc-disk property are codimension one manifold factors. We then show how the piecewise disjoint arc-disk property and other general position properties that detect codimension one manifold factors are related. We also note that in every example presently known to the authors of a codimension one manifold factor of dimension $n\geq 4$ determined by general position properties, the piecewise disjoint arc-disk property is satisfied.

description: A wide range of models beyond the Standard Model predict charged and neutral resonances, generically called $W'$- and $Z'$-bosons, respectively. In this paper we study the impact of such resonances on the deep inelastic scattering of ultra-high energy neutrinos as well as on the resonant charged current $\barν_e e^-$ scattering (Glashow resonance). We find that the effects of such resonances can not be observed with the Pierre Auger Observatory or any foreseeable upgrade of it.
