description: Transfer of amplitude and phase noise from a continuous wave optical pump to the repetition rate of a Kerr frequency comb is studied theoretically, with focus on generation of spectrally pure radio frequency (RF) signals via demodulation of the frequency comb on a fast photodiode. It is shown that both the high order chromatic dispersion of the resonator spectrum and frequency-dependent quality factor of the resonator modes facilitate the optical-to-RF noise conversion that limits spectral purity of the RF signal.

description: Response to weekly evidence-based PTSD treatments varies. Little is known about response trajectories and predictors in intensive PTSD treatments. This study sought to identify different trajectories of symptom change among veterans who completed a 3-week CPT-based intensive PTSD treatment program and examined potential predictors of trajectory group membership. Four hundred fifty-two veterans completed the program. Demographics, PTSD and depression severity, negative posttrauma cognitions, and alcohol use were assessed at intake and evaluated as possible predictors of group membership. Group based trajectory modeling was used to determine distinct groups based on PTSD symptom trajectory over the course of treatment, as well as predictors of group membership. Four distinct treatment trajectories were identified: Fast responders (15.3%), steady responders (32.0%), partial responders (38.4%), and minimal responders (14.4%). Fast and steady responders reported substantial symptom reductions and dropped below the "probable PTSD" threshold, with fast responders achieving improvements after just one week of treatment. Partial responders experienced clinically significant reductions but remained above the "probable PTSD" threshold. Minimal responders reported the highest baseline PTSD symptoms and changed the least throughout treatment. Negative posttrauma cognitions as well as self-reported and clinician-rated PTSD symptom severity assessed at intake successfully predicted trajectory membership. The identified trajectories closely resemble findings in the limited existing literature on intensive PTSD treatment trajectories. Results suggest that some individuals may improve with even shorter interventions and others might benefit from additional treatment sessions. Overall, findings support the importance of evaluating individual- and group-level treatment responses.

description: Due to the increased capabilities of mobile devices and through wireless opportunistic contacts, users can experience new ways to share and retrieve content anywhere and anytime, even in the presence of link intermittency. Due to the significant number of available routing solutions, it is difficult to understand which one has the best performance, since all of them follow a different evaluation method. This paper proposes an assessment model, based on a new taxonomy, which comprises an evaluation guideline with performance metrics and experimental setup to aid designers in evaluating solutions through fair comparisons. Simulation results based on the proposed model revisit the performance results published by Epidemic, PROPHET, and Bubble Rap, showing how they perform under the same set of metrics and scenario.

A MUltiwavelength Study of ELAN Environments (AMUSE2) : A systematic submillimeter survey around quasars hosting Lyman-alpha nebulae at z=2-4

Publisher: name: Zenodo

description: Studies on the formation of structures have a profound impact on cosmology and galaxy formation. Investigating protoclusters and their associated members during cosmic noon offers an excellent opportunity to test how massive galaxies assemble their masses and how their formation mechanisms are influenced by the environment. However, research on protoclusters has been hindered by small sample sizes and the use of heterogeneous data sets, which limit our ability to draw definitive conclusions. To address these issues, we have conducted a submillimeter survey around a sample of 20 bright quasars hosting Lyman-alpha nebulae at z=2-4. This survey complements previous studies by providing insights into obscured star formation processes. Our findings provide statistical evidence for the widespread presence of dusty star-forming galaxies (DSFGs) around these quasars. Moreover, these DSFGs appear to align with filamentary structures on a scale of several megaparsecs (Mpc). Additionally, we observed that the alignment of these filamentary structures coincides with the major axis of the Lyman-alpha nebulae, suggesting that the nebulae, which are hundreds of kpc across, trace the central regions of the large-scale structure described by the submillimeter galaxies on Mpc scales. Finally, I also present results from our ALMA follow-up observations, aimed at confirming the membership of these DSFG candidates, as well as to study the environmental impact on their physical properties.

description: The distribution of electron waiting times is useful to characterize quantum transport in mesoscopic structures. Here we consider a generic quantum-coherent conductor consisting of a mesoscopic scatterer in a two-terminal setup. We extend earlier results for single-channel conductors to setups with several (possibly spin-degenerate) conduction channels and we discuss the effect of a finite electronic temperature. We present detailed investigations of the electron waiting times in a quantum point contact as well as in two mesoscopic interferometers with energy-dependent transmissions: a Fabry-Pérot interferometer and a Mach-Zehnder interferometer. We show that the waiting time distributions allow us to determine characteristic features of the scatterers, for instance the number of resonant levels in the Fabry-Pérot interferometer that contribute to the electronic transport.

description: This module will be developed to interconnect the predictive maintenance system with the system of automatic maintenance management (CMMS) of facilities used in COMSA. The improved CMMS will have automatic alarms linked to predictive mainte-nance developed. Previous to that COMS will determine the key operating parameters which are predictive of failure or malfunc-tion needed for corrective maintenance and interfacing with the automatic maintenance management (CMMS) while EUR will ad-dress the technical integration of the results of the algorithms of optimization and detection of failures into a maintenance manage-ment system. The module (and the integrated concept) will be tested in lab conditions with a collection of data sets, prior to its deployment in real conditions in WP6.

description: Using transient Rayleigh scattering (TRS) measurements, we obtain photoexcited carrier thermalization dynamics for both zincblende (ZB) and wurtzite (WZ) InP single nanowires (NW) with picosecond resolution. A phenomenological fitting model based on direct band to band transition theory is developed to extract the electron-hole-plasma density and temperature as a function of time from TRS measurements of single nanowires which have complex valence band structures. We find that the thermalization dynamics of hot carriers depends strongly on material (GaAs NW vs. InP NW) and less strongly on crystal structure (ZB vs. WZ). The thermalization dynamics of ZB and WZ InP NWs are similar. But a comparison of the thermalization dynamics in ZB and WZ InP NWs with ZB GaAs NW reveals more than an order of magnitude slower relaxation for the InP NWs. We interpret these results as reflecting their distinctive phonon band structures which lead to different hot phonon effects. Knowledge of hot carrier thermalization dynamics is an essential component for effective incorporation of nanowire materials into electronic devices.

description: The temporal dynamics of stimulated emission is studied, with the particular emphasis on stimulated emission induced by x-ray pulses interacting with nuclei. In typical nuclear forward scattering experiments, the short incident x-ray pulse is accompanied by a huge number of off-resonant background photons. This prompts the question, if stimulated emission can be observed in the delayed nuclear scattering signal which is emitted after the incident pulse has passed. We find that the stimulated photons essentially overlap with the stimulating pulse. To overcome this problem, we identify the reduction of the delayed scattered light intensity as alternative signature for the stimulated emission. We further study a phase-sensitive variant of stimulated emission in the low-excitation regime, which provides convenient control parameters to facilitate the detection. Finally, we analyze the possibility to observe stimulated emission in nuclei driven by free electron lasers or synchrotron radiation sources.

New insights on the properties of protoclusters in the early Universe from the James Webb Space Telescope
Creators: name: Laporte, Nicolas
Publisher: name: Zenodo
Year: 2023

description: According to the current paradigm of galaxy formation, the first galaxies likely formed within large dark matter haloes. The fragmentation of these massive haloes led to the formation of galaxy protoclusters, which are usually composed of one to a few bright objects, surrounded by numerous fainter (and less massive) galaxies. These early structures could have played a major role in reionising the neutral hydrogen within the first billion years of the Universe, especially if their number density is significant. Taking advantage of the unprecedented sensitivity reached by the James Webb Space Telescope (JWST), galaxy protoclusters can now be identified and studied in increasing numbers beyond z ≥ 6. Within the first year of observation, the number of known protoclusters at z>6 has strongly increased and span a huge range of redshift up to z=10.6. In this talk, I will describe the properties of a lensed protocluster at z=7.66 identified behind SMACS0723. I will also discuss evidences of a possible protocluster at z=10.6 in GOODS-South.
Rate of convergence and stability analysis of a modified fixed pivot technique for a fragmentation equation

description: This study presents the convergence and stability analysis of a recently developed fixed pivot technique for fragmentation equations (Liao et al. in Int J Numer Methods Fluids 87(4):202–215, 2018). The approach is based on preserving two integral moments of the distribution, namely (a) the zeroth-order moment, which defines the number of particles, and (b) the first-order moment, which describes the total mass in the system. The present methodology differs mathematically in a way that it delivers the total breakage rate between a mother and a daughter particle immediately, whereas existing numerical techniques provide the partial breakup rate of a mother and daughter particle. This affects the computational efficiency and makes the current model reliable for CFD simulations. The consistency and unconditional second-order convergence of the method are proved. This demonstrates efficiency of the method over the fixed pivot technique (Kumar and Warnecke in Numer Math 110(4):539–559, 2008) and the cell average technique (Kumar and Warnecke in Numer Math 111(1):81–108, 2008). Numerical results are compared against the cell average technique and the experimental order of convergence is calculated to confirm the theoretical order of convergence.

description: We investigate the limits of effectiveness of classical spin simulations for predicting free induction decays (FIDs) measured by solid-state nuclear magnetic resonance (NMR) on systems of quantum nuclear spins. The specific limits considered are associated with the range of interaction, the size of individual quantum spins and the long-time behavior of the FID signals. We compare FIDs measured or computed for lattices of quantum spins (mainly spins 1/2) with the FIDs computed for the corresponding lattices of classical spins. Several cases of excellent quantitative agreement between quantum and classical FIDs are reported along with the cases of gradually decreasing quality of the agreement. We formulate semi-empirical criteria defining the situations, when classical simulations are expected to accurately reproduce quantum FIDs. Our findings indicate that classical simulations may be a quantitatively accurate tool of first principles calculations for a broad class of macroscopic systems, where individual quantum microscopic degrees of freedom are far from the classical limit.

description: In 2015, the United States Department of Health and Human Services instantiated rules mandating the inclusion of sexual orientation and gender identity (SO/GI) data fields for systems certified under Stage 3 of the Meaningful Use of Electronic Health Records (EHR) program. To date, no published assessments have benchmarked implementation penetration and data quality. To establish a benchmark for a U.S. health system collection of gender identity and sex assigned at birth, we analyzed one urban academic health center's EHR data; specifically, the records of patients with unplanned hospital admissions during 2020 (N = 49,314). Approximately one-quarter of patient records included gender identity data, and one percent of them indicated a transgender or nonbinary (TGNB) status. Data quality checks suggested limited provider literacy around gender identity as well as limited provider and patient comfort levels with gender identity disclosures. Improvements are needed in both provider and patient literacy and comfort around gender identity in clinical settings. To include TGNB populations in informatics-based research, additional novel approaches, such as natural language processing, may be needed for more comprehensive and representative TGNB cohort discovery. Community and stakeholder engagement around gender identity data collection and health research will likely improve these implementation efforts.

description: We generalise uniqueness theorems for non-extremal black holes with three mutually independent Killing vector fields in five-dimensional minimal supergravity in order to account for the existence of non-trivial 2-cycles in the domain of outer communication. The black hole space-times we consider may contain multiple disconnected horizons and be asymptotically flat or asymptotically Kaluza-Klein. We show that in order to uniquely specify the black hole space-time, besides providing its domain structure and a set of asymptotic and local charges, it is necessary to measure the magnetic fluxes that support the 2-cycles as well as fluxes in the two semi-infinite rotation planes of the domain diagram.

description: We develop a maximum likelihood estimating approach for time-to-event Weibull regression models with outcome-dependent sampling, where sampling of subjects is dependent on the residual fraction of the time left to developing the event of interest. Additionally, we propose a two-stage approach which proceeds by iteratively estimating, through a pseudo score, the Weibull parameters of interest (i.e., the regression parameters) conditional on the inverse probability of sampling weights; and then re-estimating these weights (given the updated Weibull parameter estimates) through the profiled full likelihood. With these two new methods, both the estimated sampling mechanism parameters and the Weibull parameters are consistently estimated under correct specification of the conditional referral distribution. Standard errors for the regression parameters are obtained directly from inverting the observed information matrix in the full likelihood specification and by either calculating bootstrap or robust standard errors for the hybrid pseudo score/profiled likelihood approach. Loss of efficiency with the latter approach is considered. Robustness of the proposed methods to misspecification of the referral mechanism and the time-to-event distribution is also briefly examined. Further, we show how to extend our methods to the family of parametric time-to-event distributions characterized by the generalized gamma distribution. The motivation for these two approaches came from data on time to cirrhosis from hepatitis C viral infection in patients referred to the Edinburgh liver clinic. We analyze these data here.

description: The influence of short-range correlations on the spectral distribution of neutrons is incorporated in the solution of the gap equation for the ${}^3P_2-{}^3F_2$ coupled channel in pure neutron matter. This effect is studied for different realistic interactions including one based on chiral perturbation theory. The gap in this channel vanishes at all relevant densities due to the treatment of these correlations. We also consider the effect of long-range correlations by including polarization terms in addition to the bare interaction which allow the neutrons to exchange density and spin fluctuations governed by the strength of Landau parameters allowed to have reasonable values consistent with the available literature. Preliminary results indicate that reasonable values of these parameters do not generate a gap in the ${}^3P_2-{}^3F_2$ coupled channel either for all three realistic interactions although the pairing interaction becomes slightly more attractive.

description: In perception simulation for autonomous driving, GNSS sensor output is generally challenging to simulate due to the multiple time- and location-varying sources of error that impact its operation. City landscapes pose modelling challenges in that their buildings and urban canyons (referred to as topographic elements from now) limit the ego GNSS’ view of satellites in the sky, causing sky-impairment that impacts GNSS availability. In this extended abstract, we outline an efficient approach based on Geometric Ray Tracing to computing a GNSS Receiver’s Sky View Factor in an urban landscape filled with topographical elements that occlude its satellite communications.
A class of unambiguous state discrimination problems achievable by separable measurements but impossible by local operations and classical communication
Creators: name: Cohen, Scott M.

Year: 2014
Subjects: subject: Quantum Physics (quant-ph)

description: We consider an infinite class of unambiguous quantum state discrimination problems on multipartite systems, described by Hilbert space $\cal{H}$, of any number of parties. Restricting consideration to measurements that act only on $\cal{H}$, we find the optimal global measurement for each element of this class, achieving the maximum possible success probability of $1/2$ in all cases. This measurement turns out to be both separable and unique, and by our recently discovered necessary condition for local quantum operations and classical communication (LOCC), it is easily shown to be impossible by any finite-round LOCC protocol. We also show that, quite generally, if the input state is restricted to lie in $\cal{H}$, then any LOCC measurement on an enlarged Hilbert space is effectively identical to an LOCC measurement on $\cal{H}$. Therefore, our necessary condition for LOCC demonstrates directly that a higher success probability is attainable for each of these problems using general separable measurements as compared to that which is possible with any finite-round LOCC protocol.

description: We show that both the power and repetition rate of a frequency comb generated in a nonlinear ring resonator, pumped with continuous wave (cw) coherent light, are modulated. The modulation is brought about by the interaction of the cw background with optical pulses excited in the resonator, and occurs in resonators with nonzero high-order chromatic dispersion and wavelength-dependent quality factor. The modulation frequency corresponds to the detuning of the pump frequency from the eigenfrequency of the pumped mode in the resonator.

description: Let $L_0$ be a bounded operator on a Banach space, and consider a perturbation $L=L_0+K$, where $K$ is compact. This work is concerned with obtaining bounds on the number of eigenvalues of $L$ in subsets of the complement of the essential spectrum of $L_0$, in terms of the approximation numbers of the perturbing operator $K$. Our results can be considered as wide generalizations of classical results on the distribution of eigenvalues of compact operators, which correspond to the case $L_0=0$. They also extend previous results on operators in Hilbert space. Our method employs complex analysis and a new finite-dimensional reduction, allowing us to avoid using the existing theory of determinants in Banach spaces, which would require strong restrictions on $K$. Several open questions regarding the sharpness of our results are raised, and an example is constructed showing that there are some essential differences in the possible distribution of eigenvalues of operators in general Banach spaces, compared to the Hilbert space case.

description: BACKGROUND: Opioid misuse screening in hospitals is resource-intensive and rarely done. Many hospitalized patients are never offered opioid treatment. An automated approach leveraging routinely captured electronic health record (EHR) data may be easier for hospitals to institute. We previously derived and internally validated an opioid classifier in a separate hospital setting. The aim is to externally validate our previously published and open-source machine-learning classifier at a different hospital for identifying cases of opioid misuse. METHODS: An observational cohort of 56,227 adult hospitalizations was examined between October 2017 and December 2019 during a hospital-wide substance use screening program with manual screening. Manually completed Drug Abuse Screening Test served as the reference standard to validate a convolutional neural network (CNN) classifier with coded word embedding features from the clinical notes of the EHR. The opioid classifier utilized all notes in the EHR and sensitivity analysis was also performed on the first 24 h of notes. Calibration was performed to account for the lower prevalence than in the original cohort. RESULTS: Manual screening for substance misuse was completed in 67.8% (n = 56,227) with 1.1% (n = 628) identified with opioid misuse. The data for external validation included 2,482,900 notes with 67,969 unique clinical concept features. The opioid classifier had an AUC of 0.99 (95% CI 0.99-0.99) across the encounter and 0.98 (95% CI 0.98-0.99) using only the first 24 h of notes. In the calibrated classifier, the sensitivity and positive predictive value were 0.81 (95% CI 0.77-0.84) and 0.72 (95% CI 0.68-0.75). For the first 24 h, they were 0.75 (95% CI 0.71-0.78) and 0.61 (95% CI 0.57-0.64). CONCLUSIONS: Our opioid misuse classifier had good discrimination during external validation. Our model may provide a comprehensive and automated approach to opioid misuse identification that augments current workflows and overcomes manual screening barriers.

description: Le 'PROGRAMME PRIMAROSA SUD 1' (Paleoclimatic Research In Mediterranean Atlantic Record Overflow Sedimentary Activity) est inclus dans la campagne MD140/PRIVILEGE (Programme Intégré Valorisé par l'IFREMER, le LSCE, l'EPOC en GEologie).Variabilité paléoclimatique fini Quaternaire, Relation Océan-Continent. Le programme PRIMAROSA s'intéresse à 2 volets essentiels, l'un focalisé sur la paléoclimatologie, l'autre à l'identification des corps profonds. Correspond à la recherche de la variabilité climatique des 450 000 dernières années avec une focalisation particulière sur la comparaison entre évolution de l'interglaciaire actuel Holocène et celle de son plus proche analogue " astronomiquement " parlant l'Holsteinien (stade isotopique 11). L'aptitude à prédire les changements climatiques futurs nécessite la connaissance de la variabilité naturelle du climat aux cours du passé et cela sur plusieurs cycles glaciaires - interglaciaires et à haute résolution sur les 10 000 dernières années. Il est donc indispensable de poursuivre les études fortement pluridisciplinaires basées sur une grande variabilité de traceur biologique, sédimentologique et géochimique sur des séries sédimentaires longues (carottages CALYPSO) ou correspondant à la sédimentation récente (carottages CASQ). Ce volet paléoclimatique est également abordé par le biais d'appareils sédimentaires profonds du golfe de Cadix. Cette zone correspond en effet à l'édification de structure réductrice sur le fond en relation avec la variabilité des flux d'eaux profondes sortant de la Méditerranée via Gibraltar. Cette variabilité est en relation avec les changements environnementaux des masses d'eau de surface et de fond et à l'environnement climatique continentale (régime des vents)

description: Meta-analysis techniques have been widely developed and applied in genomic applications, especially for combining multiple transcriptomic studies. In this paper we propose an order statistic of $p$-values ($r$th ordered $p$-value, rOP) across combined studies as the test statistic. We illustrate different hypothesis settings that detect gene markers differentially expressed (DE) 'in all studies," "in the majority of studies"' or "in one or more studies," and specify rOP as a suitable method for detecting DE genes "in the majority of studies." We develop methods to estimate the parameter $r$ in rOP for real applications. Statistical properties such as its asymptotic behavior and a one-sided testing correction for detecting markers of concordant expression changes are explored. Power calculation and simulation show better performance of rOP compared to classical Fisher's method, Stouffer's method, minimum $p$-value method and maximum $p$-value method under the focused hypothesis setting. Theoretically, rOP is found connected to the naïve vote counting method and can be viewed as a generalized form of vote counting with better statistical properties. The method is applied to three microarray meta-analysis examples including major depressive disorder, brain cancer and diabetes. The results demonstrate rOP as a more generalizable, robust and sensitive statistical framework to detect disease-related markers.

Position-dependent stochastic diffusion model of ion channel gating

description: A position-dependent stochastic diffusion model of gating in ion channels is developed by considering the spatial variation of the diffusion coefficient between the closed and open states. It is assumed that a sensor which regulates the opening of the ion channel experiences Brownian motion in a closed region $R_{c}$ and a transition region $R_{m}$, where the dynamics is described by probability densities $p_{c}(x,t)$ and $p_{m}(x,t)$ which satisfy interacting Fokker-Planck equations with diffusion coefficient $D_{c}(x)=D_{c}\exp(γ_{c}x)$ and $D_{m}(x)=D_{m} \exp(-γ_{m}x)$. The analytical solution of the coupled equations may be approximated by the lowest frequency relaxation, a short time after the application of a depolarizing voltage clamp, when $D_{m} \ll D_{c}$ or the diffusion parameter $γ_{m}$ is sufficiently large. Thus, an empirical rate equation that describes gating transitions may be derived from a stochastic diffusion model if there is a large diffusion (or potential) barrier between open and closed states.

title: Just Criticality: A Justice Framework for Critical Minerals Value Chains

description: Critical minerals are essential in addressing today's global challenges, like technology advancement, transport, and security, with climate change at the forefront as they play a crucial role in the energy transition. However, criticality assessments have primarily evaluated and classified minerals as ‘critical’ based on their utility in the global north (developed countries), limiting their considerations to supply risk and economic importance. This has left out concerns pertinent to the global south (developing countries), which this thesis seeks to investigate. Using DRC and Zambia, China and the EU, the thesis employs a case study methodology to analyse and study the nature of the critical mineral industry in developing and developed countries that are key to the critical minerals global value chain. The thesis narrows global critical mineral value chains using the copper-cobalt value chain from extraction in host critical mineral-rich countries to processing and refining in Asian countries and consumption in the Global North. This thesis finds that the criteria used in assessing criticality do not fulfil developing countries' justice and sustainable development ambitions and perspectives. The findings show that criticality assessments drive the supply and demand of critical minerals due to a polarised global north-centric system of assessing these minerals. Several challenges experienced in the host critical mineral communities are yet to be represented. The injustices are reflected in social, economic, ecological, political, technological and governance aspects. Even though critical minerals are spatially distributed globally, these justice challenges are more pronounced in areas with weak institutional structures in the Global South. Using the tenets of justice (Procedural, Distributive, Recognition, Restorative and Cosmopolitan Justice), the thesis creates a synergy between the polarised criticality considerations of critical minerals between the Global North and Global South. The thesis advances a ‘Just Holistic Framework for Critical Minerals Value Chains’ that combines criticality considerations of the two polarised worlds to facilitate global sustainability while addressing climate change, emphasising issues of the developing world. The thesis contributes to policy and literature by reconfiguring socio-legal studies in mining law. It combines elements of justice from classical Rawlsian justice theories to current pressing concerns using the Just Holistic Framework. The thesis also contributes to policy development by addressing the need for a holistic approach when dealing with critical minerals with extraterritorial implications, thus highlighting the need for international cooperation. Lastly, the thesis contributes to the literature by advancing other criticality factors that can later be evaluated in other disciplines such as geology, physics and economics when evaluating critical minerals.
Gaining (Mutual) Information about Quark/Gluon Discrimination

description: Discriminating quark jets from gluon jets is an important but challenging problem in jet substructure. In this paper, we use the concept of mutual information to illuminate the physics of quark/gluon tagging. Ideal quark/gluon separation requires only one bit of truth information, so even if two discriminant variables are largely uncorrelated, they can still share the same "truth overlap". Mutual information can be used to diagnose such situations, and thus determine which discriminant variables are redundant and which can be combined to improve performance. Using both parton showers and analytic resummation, we study a two-parameter family of generalized angularities, which includes familiar infrared and collinear (IRC) safe observables like thrust and broadening, as well as IRC unsafe variants like $p_T^D$ and hadron multiplicity. At leading-logarithmic (LL) order, the bulk of these variables exhibit Casimir scaling, such that their truth overlap is a universal function of the color factor ratio $C_A/C_F$. Only at next-to-leading-logarithmic (NLL) order can one see a difference in quark/gluon performance. For the IRC safe angularities, we show that the quark/gluon performance can be improved by combining angularities with complementary angular exponents. Interestingly, LL order, NLL order, Pythia 8, and Herwig++ all exhibit similar correlations between observables, but there are significant differences in the predicted quark/gluon discrimination power. For the IRC unsafe angularities, we show that the mutual information can be calculated analytically with the help of a nonperturbative "weighted-energy function", providing evidence for the complementarity of safe and unsafe observables for quark/gluon discrimination.
