description: We present 8.5 arcsec resolution 1.1mm continuum imaging and CO spectroscopic redshift measurements of eight extremely bright submillimetre galaxies identified from the Planck and Herschel surveys, taken with the Large Millimeter Telescope's AzTEC and Redshift Search Receiver instruments. We compiled a candidate list of high redshift galaxies by cross-correlating the Planck Surveyor mission's highest frequency channel (857 GHz, FWHM = 4.5 arcmin) with the archival Herschel Spectral and Photometric Imaging Receiver (SPIRE) imaging data, and requiring the presence of a unique, single Herschel counterpart within the 150 arcsec search radius of the Planck source positions with 350 micron flux density larger than 100 mJy, excluding known blazars and foreground galaxies. All eight candidate objects observed are detected in 1.1mm continuum by AzTEC bolometer camera, and at least one CO line is detected in all cases with a spectroscopic redshift between 1.3 < z(CO) < 3.3. Their infrared spectral energy distributions mapped using the Herschel and AzTEC photometry are consistent with cold dust emission with characteristic temperature between $T_d$ = 43 K and 84 K. With apparent infrared luminosity of up to L(IR) = $3\times10^{14} μ^{-1} L_\odot$, they are some of the most luminous galaxies ever found (with yet unknown gravitational magnification factor $μ$). The analysis of their spectral energy distributions (SEDs) suggests that star formation is powering the bulk of their extremely large IR luminosities. Derived molecular gas masses of $M_{H2}=(0.6-7.8)\times 10^{11} M_\odot$ (for $μ$~10) also make them some of the most gas-rich high redshift galaxies ever detected.

description: Introduction/Rationale: There is a high prevalence of problem gambling among people experiencing poverty/homelessness, but several barriers contribute to low rates of formal treatment access. Assisting people with self-management strategies may be one solution to this problem. Self-management has been identified as an important occupation for people experiencing poverty/homelessness. There is growing interest in the potential of self-management strategies for problem gambling.Objectives: In this qualitative study, we aimed to describe the gambling self-management strategies among people experiencing problem gambling, poverty/homelessness, and complex health issues in a large multiethnic city in Canada.Method/Approach: Semi-structured interviews and a brief demographic survey with 19 adults experiencing problem gambling, poverty/homelessness, and complex health issues was conducted. Inductive qualitative content analysis was used to analyze participants’ gambling self-management strategies, which were then interpreted through an occupational lens.Results and or Practice Implications: Five types of gambling self-management strategies were identified: (1) seeking information on problem gambling, (2) talking about gambling problems, (3) limiting money spent on gambling, (4) avoiding gambling providers, and (5) engaging in alternative activities. These themes speak to proactive actions that directly address problem gambling issues as well as actions that result in the avoidance of things to prevent themselves from gambling. These findings can be leveraged to promote occupational self-management supports.Conclusion: Self-management was a central occupation in participants’ everyday lives, shaping their orientations to and understandings of a range situations, activities, and relationships. A combination of these strategies may be used in occupation-based interventions to effectively promote self-management skills.

description: We observed the 2015 July-August long outburst of V1006 Cyg and established this object to be an SU UMa-type dwarf nova in the period gap. Our observations have confirmed that V1006 Cyg is the second established object showing three types of outbursts (normal, long normal and superoutbursts) after TU Men. We have succeeded in recording the growing stage of superhumps (stage A superhumps) and obtained a mass ratio of 0.26-0.33, which is close to the stability limit of tidal instability. This identification of stage A superhumps demonstrated that superhumps indeed slowly grow in systems near the stability limit, the idea first introduced by Kato et al. 2014, arXiv:1406.6428). The superoutburst showed a temporary dip followed by a rebrightening. The moment of the dip coincided with the stage transition of superhumps, and we suggest that stage C superhumps is related to the start of the cooling wave in the accretion disk. We interpret that the tidal instability was not strong enough to maintain the disk in the hot state when the cooling wave started. We propose that the properties commonly seen in the extreme ends of mass ratios (WZ Sge-type objects and long-period systems) can be understood as a result of weak tidal effect.

description: Density matrix embedding theory (DMET) describes finite fragments in the presence of a surrounding environment. In contrast to most embedding methods, DMET explicitly allows for quantum entanglement between both. In this chapter, we discuss both the ground-state and response theory formulations of DMET, and review several applications. In addition, a proof is given that the local density of states can be obtained by working with a Fock space of bath orbitals.

description: We have characterized the strength of the interfacial Dyzaloshinskii-Moriya interaction (DMI) in ultrathin perpendicularly magnetized CoFeB/MgO films, grown on different underlayers of W, TaN, and Hf, using two experimental methods. First, we determined the effective DMI field from measurements of field-driven domain wall motion in the creep regime, where applied in-plane magnetic fields induce an anisotropy in the wall propagation that is correlated with the DMI strength. Second, Brillouin light spectroscopy was employed to quantify the frequency non-reciprocity of spin waves in the CoFeB layers, which yielded an independent measurement of the DMI. By combining these results, we show that DMI estimates from the different techniques only yield qualitative agreement, which suggests that open questions remain on the underlying models used to interpret these results.

description: In the last decade, much theoretical research has focused on studying the strong coupling between organic molecules (or quantum emitters, in general) and light modes. The description and prediction of polaritonic phenomena emerging in this light-matter interaction regime have proven to be difficult tasks. The challenge originates from the enormous number of degrees of freedom that need to be taken into account, both in the organic molecules and in their photonic environment. On the one hand, the accurate treatment of the vibrational spectrum of the former is key, and simplified quantum models are not valid in many cases. On the other hand, most photonic setups have complex geometric and material characteristics, with the result that photon fields corresponding to more than just a single electromagnetic mode contribute to the light-matter interaction in these platforms. Moreover, loss and dissipation, in the form of absorption or radiation, must also be included in the theoretical description of polaritons. Here, we review and offer our own perspective on some of the work recently done in the modelling of interacting molecular and optical states with increasing complexity.

description: Trap antenna is well known method and has many applications. With this method, trap(s) are used on antenna to block currents of some frequencies and so electrically divide the antenna into multiple segments and thus one antenna can work on multiple frequencies. In this paper, trap antenna method is used to design a dual band Sub GHz printed F-antenna. The antenna is printed on FR4 board to achieve low cost solution. The two bands are 865-870 MHz and 902-928 MHz. The challenge of this design is that the frequency separation of the two bands is very small. In this case, and also the extra section for low frequency band is too small. Then, the influence of trap LC component variation due to tolerance to the two resonant frequencies is big, and so it is difficult to achieve good in band return loss within the LC tolerance. This is the main difficulty of this design. The problem is solved by placing the low band section away from the end of the antenna.

description: Given $B_1(0)$ the unit ball of $\mathbb{R}^n$ ($n\geq 3$), we study smooth positive singular solutions $u\in C^2(B_1(0)\setminus \{0\})$ to $-Δu=\frac{u^{2^\star(s)-1}}{|x|^s}-μu^q$. Here $0< s<2$, $2^\star(s):=2(n-s)/(n-2)$ is critical for Sobolev embeddings, $q>1$ and $μ> 0$. When $μ=0$ and $s=0$, the profile at the singularity $0$ was fully described by Caffarelli-Gidas-Spruck. We prove that when $μ>0$ and $s>0$, besides this profile, two new profiles might occur. We provide a full description of all the singular profiles. Special attention is accorded to solutions such that $\liminf_{x\to 0}|x|^{\frac{n-2}{2}}u(x)=0$ and $\limsup_{x\to 0}|x|^{\frac{n-2}{2}}u(x)\in (0,+\infty)$. The particular case $q=(n+2)/(n-2)$ requires a separate analysis which we also perform.

description: The recently demonstrated electroluminescence of color centers in diamond makes them one of the best candidates for room temperature single-photon sources. However, the reported emission rates are far off what can be achieved by state-of-the-art electrically driven epitaxial quantum dots. Since the electroluminescence mechanism has not yet been elucidated, it is not clear to what extent the emission rate can be increased. Here we develop a theoretical framework to study single-photon emission from color centers in diamond under electrical pumping. The proposed model comprises electron and hole trapping and releasing, transitions between the ground and excited states of the color center as well as structural transformations of the center due to carrier trapping. It provides the possibility to predict both the photon emission rate and the wavelength of emitted photons. Self-consistent numerical simulations of the single-photon emitting diode based on the proposed model show that the photon emission rate can be as high as 100 kcounts s$^{-1}$ at standard conditions. In contrast to most optoelectronic devices, the emission rate steadily increases with the device temperature achieving of more than 100 Mcount s$^{-1}$ at 500 K, which is highly advantageous for practical applications. These results demonstrate the potential of color centers in diamond as electrically driven non-classical light emitters and provide a foundation for the design and development of single-photon sources for optical quantum computation and quantum communication networks operating at room and higher temperatures.

description: Faba bean is the main source of protein and minerals for most of Ethiopia’s population. However, soil fertility challenges production, and good agricultural practices are needed to increase yield and nutritional value. Pot and field experiments were conducted to evaluate the effect of the sole and combined application of biostimulants on faba bean growth, yield, and seed nutrient content. Effects of sole and/or combined applications of plant growth-promoting rhizobacteria (PGPR) (Bacillus subtilis, Pseudomonas fluorescens, and Rhizobium leguminosarum) and moringa leaf extract (MLE) were pre-evaluated under greenhouse conditions. Subsequently, selected treatments from this pot experiment were further evaluated on a local and Moti faba bean variety under field conditions on Nitisol and Vertisol. The biostimulant treatments significantly improved faba bean growth under greenhouse conditions. However, they did not influence the crop’s growth, yield, and seed nutrient content under field conditions. Varieties significantly (p < 0.05) influenced yields and yield components obtained from Vertisol, as well as seed micronutrient contents from both soils. A local variety was found to have higher nutrient content. Meanwhile, grain yield had a positive correlation with seed iron (Fe) content and a negative correlation with seed selenium (Se) and phosphorus (P) contents. In addition, seed Se content strongly correlated with P content. From this study, it could be concluded that using biostimulants does not help in improving faba bean attributes under field conditions. However, further examination of a wider range of biostimulants under field conditions is required to uncover their realistic effectiveness for bean crop biofertilization.

description: In this paper, we investigate detectability and identifiability of attacks on linear dynamical systems that are subjected to external disturbances. We generalize a concept for a security index, which was previously introduced for static systems. The generalized index exactly quantifies the resources necessary for targeted attacks to be undetectable and unidentifiable in the presence of disturbances. This information is useful for both risk assessment and for the design of anomaly detectors. Finally, we show how techniques from the fault detection literature can be used to decouple disturbances and to identify attacks, under certain sparsity constraints.

description: A probabilistic algorithm for preparing Bethe eigenstates of the spin-1/2 Heisenberg spin chain on a quantum computer has recently been found. We derive an exact formula for the success probability of this algorithm in terms of the Gaudin determinant, and we study its large-length limit. We demonstrate the feasibility of computing antiferromagnetic ground-state spin-spin correlation functions for short chains. However, the success probability decreases exponentially with the chain length, which precludes the computation of these correlation functions for chains of moderate length. Some conjectures for estimates of the Gaudin determinant are noted in an appendix.

Decoherence by Internal Degrees of Freedom

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider a composite system consisting of coupled particles, and investigate decoherence due to coupling of the center-of-mass degree of freedom with the internal degrees of freedom. For a simple model of two bound particles, we show that in general such a decoherence effect exists, and leads to suppression of interference between different paths of the center-of-mass. For the special case of two harmonically-bound particles moving in an external potential in one dimension, we show that the coupling between the center-of-mass and internal degrees of freedom can be approximated as parametric driving, and that nontrivial coupling depends on the second derivative of the external potential. We find a partial solution to this parametric driving problem. For a simple interference experiment, consisting of two wave packets scattering off of a square well, we perform numerical simulations and show a close connection between suppression of interference and entanglement between the center-of-mass and internal degrees of freedom. We also propose a measure of compositeness which quantifies the extent to which a composite system cannot be approximated as a single, indivisible particle. We numerically calculate this quantity for our square well example system.

description: Circular features in forests seen from air have been studied for several decades at different locations around the world. Forest rings, as they are called in Canada’s boreal forests, express several geochemical (pH, carbonate content) and geophysical (surface potential) anomalies on their 20–30 m wide ring edges. Although it has been proposed that microbial processes may cause these anomalies, the exact mechanisms of ring formation are still unknown. We focused on the Thorn North forest ring in Ontario, Canada to correlate the surface potential anomaly to soil gas concentrations. Field measurements showed that the surface potential drop at the ring edge center is framed by peaks in CO2 production, which is linked to O2 depletion and methane generation. Carbon isotope signatures were found to drop to lighter values (down to −20‰), suggesting increased respiration. Higher concentrations of uronic acids bound to extracellular polymeric substances were found, indicating that the surface potential anomaly is linked to respiration. 16S rRNA gene sequencing of shallow soil did not indicate a dominant microbial group on the edges; instead, principal component analysis showed that the microbial composition was controlled by the substrate (clayey vs. sandy soil), therefore future studies should focus on deeper ground layers.

description: Bioreduction of Cr(VI) is an efficient and environmentally friendly remediation method. In this study, we isolated and screened a strain of Penicillium rubens LR6 that could tolerate to Cr(VI) and investigated its mechanism for removing Cr(VI). We ascertained the factors affecting the ability of strain to remove Cr(VI) through batch experiments. The results revealed that the strain could effectively remove high concentrations of Cr(VI) and exhibit excellent removal efficiency under different environmental conditions. The removal of Cr(VI) by the strain could be accurately explained by the exponential decay equation, where approximately 9.45% of the Cr was immobilized on the microorganisms. We further investigated the ability of different cell fractions to remove Cr(VI) and found that bioreduction was the primary mechanism involved. This was supported by SEM and TEM analyses, which showed the presence of Cr on the surface and inside the cells. Additionally, XPS analysis confirmed the presence of both Cr(VI) and Cr(III) on the cell surface, and FTIR analysis suggested the involvement of amino, carboxyl, and hydroxyl groups in the reduction and fixation of Cr(VI) on the cell surface. The findings offer a novel technique for bioremediation of Cr(VI)-contaminated wastewater in weakly acidic to weakly alkaline and high salinity environments, providing potential solutions for remediating chromium-contaminated environments.

description: Phosphate-solubilizing bacteria play a vital role in enhancing phosphorus availability for plants by solubilizing inorganic phosphate sources, leading to improved phosphorus, enhanced plant growth, and increased productivity. The investigation focused on evaluating the phosphate solubilizing capabilities of selected bacterial isolates on rice under controlled laboratory conditions. A total of 60 soil samples were collected from different districts in Odisha, India, and six phosphate-solubilizing bacteria (PR, PD, PSB19, PSB5, PK, and PSB16) were screened and isolated. PSB5 exhibited the highest P-solubilizing efficiency in NBRIP culture medium. Seed treatments with the bacterial isolate resulted in significant improvements compared to the control group. The treated rice plants exhibited a notable increase in height, ranging from 16.78 ± 0.17 cm to 26.48 ± 0.31 cm, along with a substantial improvement in fresh weight, ranging from 0.82 ± 0.01 gm to 1.82 ± 0.07 gm, an impressive boost in dry weight, ranging from 0.30 ± 0.01 gm to 0.65 ± 0.02 and vigor index from1428.481 to2583.876. Six bacterial isolates were assessed qualitatively for phosphate solubilization and PGP functions, out of which, four highly efficient organisms were identified. The 16S rRNA sequencing identified PR asKlebsiella pneumoniae, PD asBurkholderiaspecies strain EIKU9, PSB19 asBacillus siamensis, and PSB5 asPseudomonas guariconensis, confirming their efficiency.

description: Context. Local correlation tracking of granulation (LCT) is an important method for measuring horizontal flows in the photosphere. This method exhibits a systematic error that looks like a flow converging towards disk center, also known as the shrinking-Sun effect. Aims. We aim at studying the nature of the shrinking-Sun effect for continuum intensity data and at deriving a simple model that can explain its origin. Methods. We derived LCT flow maps by running the local correlation tracking code FLCT on tracked and remapped continuum intensity maps provided by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory. We also computed flow maps from synthetic continuum images generated from STAGGER code simulations of solar surface convection. We investigated the origin of the shrinking-Sun effect by generating an average granule from synthetic data from the simulations. Results. The LCT flow maps derived from HMI and from the simulations exhibit a shrinking-Sun effect of comparable magnitude. The origin of this effect is related to the apparent asymmetry of granulation originating from radiative transfer effects when observing with a viewing angle inclined from vertical. This causes, in combination with the expansion of the granules, an apparent motion towards disk center.

description: We study a driven-dissipative Bose-Hubbard model in presence of two-particle losses and an incoherent single-particle drive on each lattice site, leading to a finite-density stationary state. Using dynamical mean-field theory (DMFT) and an impurity solver based on exact diagonalization of the associated Lindbladian, we investigate the regime of strong two-particle losses. Here, a stationary-state quantum Zeno effect emerges, as can be seen in the on-site occupation and spectral function. We show that DMFT captures this effect through its self-consistent bath. We show that, in the deep Zeno regime, the bath structure simplifies, with the occupation of all bath sites except one becoming exponentially suppressed. As a result, an effective dissipative hard-core Bose-Hubbard dimer model emerges, where the auxiliary bath site has single-particle dissipation controlled by the Zeno dissipative scale.

description: Besides the designed beam acceleration, the energy of electrons changed by the longitudinal wakefields in a real free-electron laser (FEL) facility, which may degrade FEL performances from the theoretical expectation. In this paper, with the help of simulation codes, the wakefields induced beam energy loss in the sophisticated undulator section is calculated for Shanghai soft X-ray FEL, which is a two-stage seeded FEL test facility. While the 1st stage 44 nm FEL output is almost not affected by the wakefields, it is found that a beam energy loss about 0.8 MeV degrades the peak brightness of the 2nd stage 8.8 nm FEL by a factor of 1.6, which however can be compensated by a magnetic field fine tuning of each undulator segment.

description: The radial velocity (RV) detection of exoplanets is challenged by stellar spectroscopic variability that can mimic the presence of planets and by instrumental instability that can further obscure the detection. Both stellar and instrumental changes can distort the spectral line profiles and be misinterpreted as apparent RV shifts. We present an improved FourIEr \textit{phase} SpecTrum Analysis (FIESTA a.k.a. $\mathitϕ$ESTA) to disentangle apparent velocity shifts due to a line deformation from a true Doppler shift. $\mathitϕ$ESTA projects stellar spectrum's cross correlation function (CCF) onto a truncated set of Fourier basis functions. Using the amplitude and phase information from each Fourier mode, we can trace the line variability at different CCF width scales to robustly identify and mitigate multiple sources of RV contamination. For example, in our study of the 3 years of HARPS-N solar data, $\mathitϕ$ESTA reveals the solar rotational effect, the long-term trend due to solar magnetic cycle, instrumental instability and apparent solar rotation rate changes. Applying a multiple linear regression model on $\mathitϕ$ESTA metrics, we reduce the weighted rms noise from 1.89 m/s to 0.98 m/s. In addition, we observe a $\sim$3 days lag in the $\mathitϕ$ESTA metrics, similar to the findings from previous studies on BIS and FWHM.

description: The collision of two expanding plasma clouds is investigated, emphasizing instabilities and electron energization in the plasma mixing layer. This work is directly relevant to laboratory experiments with explosively-created laser or z-pinch plasmas but may also elucidate naturally occurring plasma collisions in astrophysical or space physics contexts. In the previous publications [1,2] we have studied, analytically and numerically, the flow emerging from interpenetrating coronas launched by two parallel wires vaporized in a vacuum chamber. The main foci of the studies have been on the general flow pattern and lower-hybrid and thin-shell instabilities that under certain conditions develop in the collision layer. The present paper centers around the initial phase of the interpenetration of the two plasmas. A two-stream ion-ion instability, efficient electron heating, and stochastic acceleration dominate plasma mixing at this phase. Both the adiabatic (reversible) electron heating and stochastic (irreversible) acceleration and heating mechanisms, powered by unstably driven electric fields, are considered. The irreversibility results from a combination of electron runaway acceleration in the wave electric fields and pitch-angle scattering on ions and neutrals.

description: Antipsychotic polypharmacy is prevalent, however literature on antipsychotic polypharmacy during treatment among patients with dual diagnosis is largely non-existent. This study aims to investigating the extent of antipsychotic polypharmacy dual diagnosis patients during hospitalisations. Utilizing cohort data from an integrated dual diagnosis in-patient facility from patients hospitalized between 1 March 2012, to 31 December 2016, we compared the mean antipsychotic medication administered at admission and discharge and examined covariate associations with logistic regressions. The study identified 907 hospital admissions, of which 641 were the first for each patient during the period. At admission, 74.1% received antipsychotics; polypharmacy spanned psychiatric disorders. categories. Patients with affective or personality spectrum disorders were less likely to have antipsychotic polypharmacy upon admission compared to those with psychosis spectrum disorders. 2013–2016 admissions presented less polypharmacy than 2012. Mean antipsychotic numbers remained unchanged for >30-day hospitalizations. Patients admitted without antipsychotic polypharmacy with an affective spectrum disorder or aged 41–50 or over 51 years old were less likely to be discharged with antipsychotic polypharmacy when compared to patients with psychosis spectrum disorder or aged 18–30 years old. Approximately three-quarters of admitted patients were treated with antipsychotic medication. Antipsychotic polypharmacy was observed across all psychiatric disorder categories, indicating potential off-label use. Addressing antipsychotic polypharmacy during treatment is challenging, even for specialised facilities. Rational antipsychotic prescribing, deprescribing protocols, and further prescription pattern research are needed.

description: Combining an x-ray free electron laser (XFEL) with high power laser drivers enables the study of phase transitions, equation-of-state, grain growth, strength, and transformation pathways as a function of pressure to 100s GPa along different thermodynamic compression paths. Future high-repetition rate laser operation will enable data to be accumulated at >1 Hz which poses a number of experimental challenges including the need to rapidly replenish the target. Here, we present a combined shock-compression and X-ray diffraction study on vol% epoxy(50)-crystalline grains(50) (slurry) targets, which can be fashioned into extruded ribbons for high repetition-rate operation. For shock-loaded NaCl-slurry samples, we observe pressure, density and temperature states within the embedded NaCl grains consistent with observations for shock-compressed single-crystal NaCl.

description: This research aimed to identify bacterial species present in six detoriated painted relief samples collected from the catacomb of Kom Al-Shoqafa cemetery in Alexandria, Egypt, and to evaluate their antibacterial susceptibility toward chitosan nanoparticles synthesized in the study. Genomic DNA from three bacterial isolates were amplified using universal 16S rDNA primers and comparative 16S rDNA sequence analysis showed that the isolates had a sequence similarity of ≥91% with Paenibacillus albidus Paenibacillus typhi and Paenibacillus wynii The 16S rDNA gene sequence of these isolates were deposited in the GenBank database under accession numbers MW644543, MW644573, and MW644586, respectively. This research provides new molecular information on the microbial diversity of ancient detoriated painting samples in Egypt. Furthermore, the antibacterial susceptibility of these three bacterial strains were tested against synthesized chitosan nanoparticles (characterized by transmission electron microscopy) employing the well diffusion method, with the nanoparticles exhibiting significant antibacterial activities. Overall, this study provides valuable information on bacterial diversity in ancient painting samples and highlights chitosan nanoparticles as potential antibacterial agents that could be implemented for the preservation of these paintings.

description: We design and implement 3D lumped element microwave cavities for the coherent and uniform coupling to electron spins hosted by nitrogen vacancy centers in diamond. Our design spatially focuses the magnetic field to a small mode volume. We achieve large homogeneous single spin coupling rates, with an enhancement of the single spin Rabi frequency of more than one order of magnitude compared to standard 3D cavities with a fundamental resonance at \SI{3}{GHz}. Finite element simulations confirm that the magnetic field component is homogeneous throughout the entire sample volume, with a RMS deviation of 1.54\%. With a sample containing $10^{17}$ nitrogen vacancy electron spins we achieve a collective coupling strength of $Ω=\SI{12}{MHz}$, a cooperativity factor $C=27$ and clearly enter the strong coupling regime. This allows to interface a macroscopic spin ensemble with microwave circuits, and the homogeneous Rabi frequency paves the way to manipulate the full ensemble population in a coherent way.

description: Explanations in XAI are typically developed by AI experts and focus on algorithmic transparency and the inner workings of AI systems. Research has shown that such explanations do not meet the needs of users who do not have AI expertise. As a result, explanations are often ineffective in making system decisions interpretable and understandable. We aim to strengthen a socio-technical view of AI by following a Human-Centered Explainable Artificial Intelligence (HC-XAI) approach, which investigates the explanation needs of end-users (i.e., subject matter experts and lay users) in specific usage contexts. One of the most influential works in this area is the XAI Question Bank (XAIQB) by Liao et al. The authors propose a set of questions that end-users might ask when using an AI system, which in turn is intended to help developers and designers identify and address explanation needs. Although the XAIQB is widely referenced, there are few reports of its use in practice. In particular, it is unclear to what extent the XAIQB sufficiently captures the explanation needs of end-users and what potential problems exist in the practical application of the XAIQB. To explore these open questions, we used the XAIQB as the basis for analyzing 12 think-aloud software explorations with subject matter experts. We investigated the suitability of the XAIQB as a tool for identifying explanation needs in a specific usage context. Our analysis revealed a number of explanation needs that were missing from the question bank, but that emerged repeatedly as our study participants interacted with an AI system. We also found that some of the XAIQB questions were difficult to distinguish and required interpretation during use. Our contribution is an extension of the XAIQB with 11 new questions. In addition, we have expanded the descriptions of all new and existing questions to facilitate their use.
