description: Iron (Fe) is a vital transition metal for virtually all living organisms. In its ionic form, this element functions as a powerful cofactor within a multitude of enzymes responsible for a wide range of complex chemical reactions including, but not limited to, de novo DNA biosynthesis, central carbon metabolism, vitamin biogenesis, and even N2 fixation. Due to its critical necessity in these essential metabolic processes, organisms such as bacteria have a high demand for the uptake of iron. However, the mode of iron acquisition is linked to the oxidation state of the iron ion, which is a product of the prevailing environmental conditions. In acidic and reducing conditions commonly encountered by pathogenic bacteria within the human gut or locations within biofilms, ferrous iron (Fe2+) dominates the environment, but the precise mechanism by prokaryotes acquire Fe2+ remains unclear. In this dissertation, the structural and biophysical characteristics of the membrane-bound and membrane-associated components of the ferrous iron transport (Feo) system, the most widely distributed and the primary Fe2+ transport system utilized by bacteria, are investigated. First, structures of the N-terminal domain of FeoB (NFeoB) from Vibrio cholerae (VcNFeoB), the causative agent of the disease cholera, are presented for the first time and give critical insight into the surprising nucleotide promiscuity of FeoB. Next, in an attempt to provide homogeneous, near-native samples of full-length, intact FeoB for future structural characterization, V. cholerae FeoB (VcFeoB) was extracted directly from bacterial membranes in near native-like lipid environments through the use of styrene-maleic acid (SMA)-copolymers. SMA-extracted VcFeoB showed high purity, good monodispersity, and displayed differences in NTP-dependent activity in the presence of lipids compared to detergent-solubilized VcFeoB. Finally, a newly discovered single-pass transmembrane protein of the Feo system termed FeoD (formally FeoI) from Streptococcus thermophilus (StFeoD) was first modeled using AlphaFold3 before being cloned, expressed, purified, and partially characterized. Contrary to previous reports, we show that the Cys-rich StFeoD co-purifies with a partially bound [Fe-S] cluster, similarly to FeoC, and optimization and further characterization is currently underway. When taken all together, this dissertation deepens our understanding of the membrane-bound and membrane-associated components of the Feo system and paves the way for future structural work to understand the precise mechanism of prokaryotic Fe2+ transport.
Very Light Jets I. Axisymmetric Parameter Study and Analytic Approximation

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)

description: The propagation of extragalactic jets is studied by a series of twelve axisymmetric hydrodynamic simulations. Motivated by observational constraints, but unlike most previous simulations, the regime of jet to external medium density (eta) from 10^-5 to 10^-2 is explored, for Mach numbers (M) between 2.6 and 26. The computational domain contained the bow shocks for the whole simulation time. The bow shocks are found to be spherical at source sizes below a critical value r1 (blastwave phase), which can reach up to 10 jet radii. [...] The numerical work is complemented by an analytic approach for the spherical phase. Extending previous work, the radial force balance could be integrated for arbitrary background density and energy input, which results in a global solution. The analytic results are shown to be consistent with the numerical work, and a lower limit to r1 can be calculated, which falls below the numerical results by a few jet radii. It is shown explicitely how a King density distribution changes the discussed aspects of the bow shock propagation. Because the jet head propagates very fast in the blastwave phase, it turns out that it is not possible to ``frustrate'' a jet by a high density environment. This is very important for the class of small radio galaxies (compact symmetric objects / GHz peaked sources): They have to be young. During its blastwave phase, a powerful jet can transfer typically 10^60 erg to the environmental gas. This is enough to balance the radiative losses in a cooling flow, if one of the cluster galaxies harbours a powerful jet every Gigayear.

description: Metal–organic frameworks (MOFs) offer disruptive potential in micro- and optoelectronics because of the unique properties of these microporous materials. Nanoscale patterning is a fundamental step in the implementation of MOFs in miniaturized solid-state devices. Conventional MOF patterning methods suffer from low resolution and poorly defined pattern edges. Here, we demonstrate the resist-free, direct X-ray and electron-beam lithography of MOFs. This process avoids etching damage and contamination and leaves the porosity and crystallinity of the patterned MOFs intact. The resulting high-quality patterns have excellent sub-50-nm resolution, and approach the mesopore regime. The compatibility of X-ray and electron-beam lithography with existing micro- and nanofabrication processes will facilitate the integration of MOFs in miniaturized devices.

description: We describe a new and consistent perturbation theory for solid-state quantum computation with many qubits. The errors in the implementation of simple quantum logic operations caused by non-resonant transitions are estimated. We verify our perturbation approach using exact numerical solution for relatively small (L=10) number of qubits. A preferred range of parameters is found in which the errors in processing quantum information are small. Our results are needed for experimental testing of scalable solid-state quantum computers.

description: We consider self tuning solutions for a brane embedded in an anti de Sitter spacetime. We include the higher derivative Gauss-Bonnet terms in the action and study singularity free solutions with finite effective Newton's constant. Using the methods of Csaki et al, we prove that such solutions, when exist, always require a fine tuning among the brane parameters. We then present a new method of analysis in which the qualitative features of the solutions can be seen easily without obtaining the solutions explicitly. Also, the origin of the fine tuning is transparent in this method.

description: Highly aggregated data is conventionally used in transportation safety omitting seasonal variations and leading to important loss of information. States in the northern region of the United States experience significant weather variations with snowfall and ice events. Crash occurrence is the highest during the winter compared to other seasons. Therefore, seasonal safety performance models would enable better safety analysis and decision-making. A new modeling approach is proposed which takes into account seasonal crash prediction. A case study is provided with crashes, operational, and weather data of urban signalized intersections from the southeast region in Wisconsin. Four seasons were considered: winter, spring, summer, and fall. The modeling approach consisted of the Multivariate Negative Multinomial to account for seasonal variations and severity classification. Functional forms of predictor variables were optimized. Measures of log-likelihood, Overdispersion, Cumulative Residual (CURE) plots, and Akaike Information Criterion (AIC) showed adequate model prediction accuracy. Crash estimates were the highest during the winter and the lowest during the spring seasons. Estimates remained below or near the annual average for the summer and fall seasons. Model performance was evaluated and results showed that seasonal model prediction and observed crash rate variations as percentage of annual estimates were similar. Seasonal estimates have a significant contribution in safety analysis in regions where snow and ice conditions are regularly experienced. Identifying locations that experience significantly higher number of crashes during the winter can contribute to target snow and ice-related crashes and evaluate the effectiveness of deicing materials, equipment, and practices.

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We investigate the possibility that the Sun could have been born in M67 by carrying out $N$-body simulations of M67-like clusters in a time-varying Galactic environment, and following the galactic orbits of stars that escape from them. We find that model clusters that occupy similar orbits to M67 today can be divided up into three groups. Hot clusters are born with a high initial $z$-velocity, depleted clusters are born on cold orbits but are destroyed by GMC encounters in the Galactic disc, and scattered clusters are born on cold orbits and survive with more than 1000 stars at an age of 4.6 Gyr. We find that all cluster models in all three cluster groups have stellar escapers that are kinematicaly similar to the Sun. Hot clusters having the lowest such fraction $f_{\odot} = 0.06$ %, whilst depleted clusters have the highest fraction, $f_{\odot} = 6.61$ %. We calculate that clusters that are destroyed in the Galactic disc have a specific frequency of escapers that end up on solar-like orbits that is $\sim$ 2 times that of escapers from clusters that survive their journey.
Socio-economic differentials in fertility in East Java 1980 : an areal analysis

Year: 1988
Subjects: subject: Fertility, Human Indonesia Jawa Timur

description: This study is an attempt to explore the association between the differences in areal socio-economic conditions and fertility across the regions in East Java. The total fertility rates (TFR) by regions are calculated based on the 1980 Population Census using Rele's method. Ten indicators of socio-economic conditions are taken from sources such as the 1980 Population Census and family planning service statistics. The 29 regencies are the units of analysis in this study. Inclusion of the 8 municipalities was found to raise spurious correlations between measure of fertility and socio-economic conditions. This is probably because the municipalities, which are mostly urban areas, have as a group very different socio-economic conditions from those of the regencies. From the correlation and regression analyses used to examine the relationships between fertility level and selected indicators, it was found that the areal differences in fertility in East Java are associated with areal differences in demographic indicators (specifically the percentage of women aged 15-49 who currently married and infant mortality rate) rather than with other indicators. In the regression analysis, the percentage of women aged 15-49 who currently married and the infant mortality rate are able to explain the variation in fertility among the regencies by 38% and 24% respectively. However, TFR and the percentage of women aged 15-49 who currently married were found to have an inverse relationship, contrary to what might be expected. This raises questions about the accuracy of the measures used, and therefore, this study needs to be verified with further research using other types of data and analysis.

description: MyShake harnesses private/personal smartphones to build a global seismic network. It uses the accelerometers embedded in all smartphones to record ground motions induced by earthquakes, returning recorded waveforms to a central repository for analysis and research. A demonstration of the power of citizen science, MyShake expanded to 6 continents within days of being launched, and has recorded 757 earthquakes in the first 2 years of operation. The data recorded by MyShake phones has the potential to be used in scientific applications, thereby complementing current seismic networks. In this paper: (1) we report the capabilities of smartphone sensors to detect earthquakes by analyzing the earthquake waveforms collected by MyShake. (2) We determine the maximum epicentral distance at which MyShake phones can detect earthquakes as a function of magnitude. (3) We then determine the capabilities of the MyShake network to estimate the location, origin time, depth and magnitude of earthquakes. In the case of earthquakes for which MyShake has provided 4 or more phases (21 events), either P- or S-wave signals, and has an azimuthal gap less than 180 degrees, the median location, origin time and depth errors are 2.7 km, 0.2 s, and 0.1 km respectively relative to USGS global catalog locations. Magnitudes are also estimated and have a mean error of 0.0 and standard deviation 0.2. These preliminary results suggest that MyShake could provide basic earthquake catalog information in regions that currently have no traditional networks. With an expanding MyShake network, we expect the event detection capabilities to improve and provide useful data on seismicity and hazards.

Subjects: subject: Japanese language Particles

description: Introduction surveys the previous treatments of these response particles, both in dictionaries, and Japanese textbooks, also those by Japanese grammarians particularly Kitagawa and Hinata. We highlight the reasons why these treatments are inadequate, noting especially their failure to distinguish between semantic and socio-pragmatic influences. In addition we al so describe a 1 so our methodo l ogi cal approach . Chapter 1 introduces the notions of speaker and addressee orientedness . This notion forms the basis of a sub-categorization of the r·esponse particles that is e 1ementary to our analysis. !n Chapter 2 we analyse the speaker-oriented response particles aa and un and attempt to explicate their semantic components . In Chapter 3 we analyse the addressee-oriented response particles hai, haa and ee and attempt to explicate their semantic components. In Chapter 4 we view the semantic components (described in Chapters 2 and 3), in terms of such socio-pragmatic features as age , gender, roles etc . While we considered it crucial that semantic and soc i o-pragm at i c components are treated independently it is our intent ion in this chapter to finally present meanings of the response particles based on both semantic and socio-pragmatic aspects of their usage .
The Minimum Tollbooth Problem in Atomic Network Congestion Games with Unsplittable Flows

Subjects: subject: Computer Science and Game Theory (cs.GT)

description: This work analyzes the minimum tollbooth problem in atomic network congestion games with unsplittable flows. The goal is to place tolls on edges, such that there exists a pure Nash equilibrium in the tolled game that is a social optimum in the untolled one. Additionally, we require the number of tolled edges to be the minimum. This problem has been extensively studied in non-atomic games, however, to the best of our knowledge, it as not been considered for atomic games before. By a reduction from the weighted CNF SAT problem, we show both the NP-hardness of the problem and the W[2]-hardness when parameterizing the problem with the number of tolled edges. On the positive side, we present a polynomial time algorithm for networks on series-parallel graphs that turns any given state of the untolled game into a pure Nash equilibrium of the tolled game with the minimum number of tolled edges.

description: With the widespread use of the Portable Document Format (PDF), it has increasingly becoming a target for malware, highlighting the need for effective detection solutions. In recent years, machine learning-based methods for PDF malware detection have grown in popularity. However, the effectiveness of ML models is closely related to the quality of the training dataset and the employed feature set. Besides, many well-known ML-based detectors require a large number of specimen features to be collected before making a decision, which can be time-consuming. This thesis addresses these challenges by proposing a two-stage approach for PDF malware detection. The initial phase focuses on rapid detection, providing an early warning against potential PDF malware attacks. Following this fast detection stage, we introduce a robust and highly reliable feature set for PDF malware identification. Our contributions are as follows: 1. Rapid Detection Methodology: Compared to traditional machine learning or neural network models, our novel, distance-based method for rapid PDF malware detection requires much less training samples. Evaluated on the Contagio dataset, our method shows that it can detect 90.50\% of malware samples using only 20 benign PDFs for model training.2. Dataset Analysis and Introduction of PdfRep: Through an examination of two widely used PDF malware datasets, namely Contagio and CIC, we find biases and representativeness issues that compromise malware detection model reliability. To mitigate these limitations, we present PdfRep, a new, more representative PDF malware dataset that outperforms existing PDF malware dataset in evaluation metrics. 3. Compact Feature Set for Enhanced Robustness: We introduce a novel set of just five features designed to optimize training efficiency and enhance the robustness of PDF malware detection systems. Experiments show that this compact feature set strengthens PDF malware detection systems against particular adversarial attacks and allows the building of highly accurate models. In summary, this thesis presents a comprehensive approach for PDF malware detection, from rapid initial alerts to the deployment of a robust, efficient detection system enhanced by a novel dataset and an optimized feature set. When taken as a whole, these developments offer significant progress to defend against PDF-based malware attacks.

description: Estimating the eigenvalues of a unitary transformation U by standard phase estimation requires the implementation of controlled-U-gates which are not available if U is only given as a black box. We show that a simple trick allows to measure eigenvalues of U\otimes U^\dagger even in this case. Running the algorithm several times allows therefore to estimate the autocorrelation function of the density of eigenstates of U. This can be applied to find periodicities in the energy spectrum of a quantum system with unknown Hamiltonian if it can be coupled to a quantum computer.

description: Many developing countries experience a high death toll among motorcycle users (both drivers and passengers), primarily due to a relatively low rate of helmet use resulting from ineffective helmet law enforcement. The objectives of this study are to explore the change in helmet use behavior due to helmet use enforcement by closed-circuit television (CCTV) camera technology with an automatic helmet use detection system and to identify the factors associated with helmet use along an urban arterial road in the city of Khon Kaen, Thailand. Data collection was carried out on 49,128 samples by video cameras installed at 5 signalized intersections during 2 periods, namely, before and during the CCTV camera enforcement. The study applied logistic regression analysis to determine factors associated with helmet use and to compare the ratio of helmet use for each variable according to the odds ratio. The study found that CCTV camera enforcement could increase helmet usage at all study intersections by 5.3%. The results imply that 4 factors, including riding status, number of passengers, day of week, and traffic conditions, significantly affected helmet use both before and during the CCTV camera enforcement. Remarkably, 2 more variables, age and police inspection, significantly affected helmet use during the CCTV camera enforcement period. This study confirms that CCTV camera enforcement can be an important driving force for changing helmet use behavior, particularly for child passengers. Moreover, CCTV camera enforcement can support enforcement by extending coverage to a 24-h period and to intersections without police inspection.

On the optical--infra-red continuum emission from equatorial discs of supergiant B[e] stars
Creators: name: Porter, John M.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Two models of the circumstellar disc around supergiant B[e] stars are discussed: an equatorial wind model produced by wind bi-stability, and a Keplerian viscous disc model. Both models are successful in providing a site for dust formation once they have cooled sufficiently. However, the optical--infra-red continuum is calculated and it is found that both models have significant trouble in accounting for observations. In particular the optical--near-IR emission is accounted for, but the dust emission is underestimated by at least an order of magnitude. Variations in the structure of the models (the temperature variation with radius, the density structure and the dust opacity) are investigated to assess how (in)appropriate the standard models are for supergiant B[e] star discs. Changing the temperature structure, and making simple dust opacity changes within the disc has little effect on the resultant continuum emission. By altering the density structure of the discs, the continuum may be accounted for by both models: the equatorial wind model requires a very flat density profile which is impossible to explain with any accelerating wind, and the viscous disc model's density structure is required to fall off less steeply with radius than would have been expected, although this may be explained from consideration of viscous processes in the disc. It is recognised that both theoretical interpretations have difficulties and unsolved problems.

description: Classification in high dimensions has gained significant attention over the past two decades since Fisher's linear discriminant analysis (LDA) is not optimal in a smaller sample size n comparing the number of variables p, i.e., p>n, which is mostly due to the singularity of the sample covariance matrix. This dissertation proposes two novel data-driven approaches to address the challenges in high-dimensional classification, both building upon Fisher's LDA. The first approach involves the development of binary classifiers using random partitioning. Rather than modifying how to estimate the sample covariance and sample mean vector in constructing a classifier, we build two types of high-dimensional classifiers using data splitting, i.e., single data splitting (SDS) and multiple data splitting (MDS). We also present a weighted version of the MDS classifier that further improves classification performance. Each of the split data sets has a smaller size of variables compared to the sample size so that LDA is applicable, and classification results can be combined with respect to minimizing the misclassification rate. We provide theoretical justification backing up our methods by comparing misclassification rates with LDA in high dimensions. The second approach proposes a high-dimensional classifier, which is a two-stage procedure serving variable selection and classification tasks. The variable selection scheme is to select covariates that belong to the discriminative set, and this approach is aimed at obtaining a better classifier, rather than choosing significant variables themselves. In the first stage, we identify discriminative variables by adopting a notion of mirror statistic, proposed recently in the literature, and LDA direction vector obtained from a regularized form of the sample covariance matrix and a James-Stein type estimator for the mean vectors. In the second stage, a new classifier is developed using the selected variables, refined with a modified ?-greedy algorithm to enhance the LDA direction vector. Both approaches are extensively validated through simulation studies and real data analysis, including DNA microarray data sets. Our methods demonstrate superior or comparable performance to existing high-dimensional classifiers, offering improved classification accuracy, effective variable selection, and robustness in various scenarios. This dissertation contributes to the field of high-dimensional statistics by providing novel, theoretically grounded, and effective methods for classification in high-dimensional spaces, with potential applications in genomics, machine learning, and other domains facing the challenges of high-dimensional data analysis.

description: This thesis addresses one of the perennial problems of political life, that of the proper relationship between the individual and the political order. In particular, it examines aspects of the political thought of two contemporary libertarian philosophers who attempt to come to terms with this problem. How much, and what kind of, freedom the individual should be allowed for ordering his private life, which influences upon others are legitimate, and how much the government should interfere, how, and in what areas, are questions of fundamental importance to ideologues, politicians and political theorists alike.

description: Cellular membranes display an incredibly diverse range of shapes, both in the plasma membrane and at membrane bound organelles. These morphologies are intricately related to cellular functions, enabling and regulating fundamental membrane processes. However, the biophysical mechanisms at the origin of these complex geometries are not fully understood from the standpoint of membrane–protein coupling. In this study, we focused on a minimal model of helicoidal ramps representative of specialized endoplasmic reticulum compartments. Given a helicoidal membrane geometry, we asked what is the distribution of spontaneous curvature required to maintain this shape at mechanical equilibrium? Based on the Helfrich energy of elastic membranes with spontaneous curvature, we derived the shape equation for minimal surfaces, and applied it to helicoids. We showed the existence of switches in the sign of the spontaneous curvature associated with geometric variations of the membrane structures. Furthermore, for a prescribed gradient of spontaneous curvature along the exterior boundaries, we identified configurations of the helicoidal ramps that are confined between two infinitely large energy barriers. Overall our results suggest possible mechanisms for geometric control of helicoidal ramps in membrane organelles based on curvature-inducing proteins.

description: Violations of road rules are common in bicycle-motor vehicle crashes, but little is known about how much this results from lack of knowledge of the rules. This article addresses the research questions of how well do drivers know the road rules related to interacting with cyclists, and what factors influence their level of knowledge. An online survey compared drivers who reported riding bicycles on Queensland roads in the previous 12 months (“cyclists”: n = 2,839) and those who did not (“drivers”: n = 4,070). A list of 10 plausible road rules (four were not actual rules) relating to interactions between motor vehicles and bicycles was presented, and participants were asked “Which of the following road rules applies in Queensland?” The response options for each item were “Yes,” “No,” and “I don’t know”. The percentages correct varied markedly across the rules, from 86.5% to 38.7% for cyclists and from 72.2% to 20.9% for drivers. Incorrect responses were generally more common than “Don’t know” responses (cyclists: 22.3% incorrect, 9.8% “Don’t know”; drivers: 29.9% incorrect, 19.6% “Don’t know”). The hierarchical regression analysis confirmed that cyclists had better road rule knowledge than drivers. In the cyclist-only model, more frequent riding was significantly associated with better road rule knowledge but explained only 3% of the total variance. Older cyclists and those living in more urbanized areas had better knowledge but age and location of residence together added only 1% to the variance explained. In the driver-only model, knowledge was better for male, older, more educated participants and those living in more urbanized areas but these variables together accounted for only 5% of the variance. The results of this study suggest that improving knowledge of some current road rules could be beneficial for cycling safety but for some other rules, improved knowledge could be detrimental for cycling safety and changing the rules to reflect shared perceptions of safe behavior may be more beneficial. For each of the rules, further research is needed to examine the links between knowledge and compliance, and the influence of compliance on the risks of bicycle–motor vehicle crashes and near misses.

description: It is shown that the potential perturbation that shifts a chosen standing wave in space is a block of potential barrier and well for every wave bump between neighbouring knots. The algorithms shifting the range of the primary localization of a chosen bound state in a potential well of finite width are as well applicable to the scattering functions if states of the continuous spectrum are considered as bound states normalized to unity but distributed on an infinite interval with vanishing density. The potential perturbations of the same type on the half-axis concentrate the scattering wave at the origin, thus creating a bound state embedded into the continuous spectrum (zero width resonance). It is an improved version of paper: Annalen der Physik, 6 (1997) 136.

description: Speeding behavior is recognized as one of the three main causes of risk on the roads and the most frequent ordinary violation among truck drivers. The study reported in this article focused on the driving anger personality trait and its role in predicting the observed speeding behavior in a sample of truck drivers. A longitudinal study design was implemented, where 93 Serbian truck drivers filled in an adapted form of the Driving Anger Scale designed to assess the amount of driving anger evoked by specific traffic situations. The drivers’ second-by-second speeding behavior data were captured using GPS tracking and recording devices installed in the vehicles over a period of six months. Hierarchical multiple linear regression was used to examine the predictive performance of driving anger. The results showed that more than three fourths of the exceeded speed ranged from 1 to 9 km/h and the highest percentage of speed events occurred in urban areas. The findings suggest that truck drivers experienced the highest level of anger in driving because of the discourteous and illegal behavior of other drivers. Younger truck drivers are more likely to drive fast compared to older drivers. Truck drivers who perform driving tasks more often and spend less time driving are more likely to participate in speed events. The results revealed that the subscales of anger, hostile gestures and traffic obstructions have a positive effect, while slow driving has a negative effect on the observed speeding behavior of truck drivers. This study confirms the predictive performance of driving anger facets. The results of the research can help us improve our understanding of the mechanisms of speeding behavior of truck drivers.

description: We present the discovery of TYC9191-519-1b (TOI-150b, TIC 271893367) and HD271181b (TOI-163b, TIC 179317684), two hot Jupiters initially detected using 30-minute cadence Transiting Exoplanet Survey Satellite TESS photometry from Sector 1 and thoroughly characterized through follow-up photometry (CHAT, Hazelwood, LCO/CTIO, El Sauce, TRAPPIST-S), high-resolution spectroscopy (FEROS, CORALIE) and speckle imaging (Gemini/DSSI), confirming the planetary nature of the two signals. A simultaneous joint fit of photometry and radial velocity using a new fitting package juliet reveals that TOI-150b is a $1.254\pm0.016\ R_J$, massive ($2.61^{+0.19}_{-0.12}\ M_J$) hot Jupiter in a $5.857$-day orbit, while TOI-163b is an inflated ($R_P$ = $1.478^{+0.022}_{-0.029} R_J$, $M_P$ = $1.219\pm0.11 M_J$) hot Jupiter on a $P$ = $4.231$-day orbit; both planets orbit F-type stars. A particularly interesting result is that TOI-150b shows an eccentric orbit ($e=0.262^{+0.045}_{-0.037}$), which is quite uncommon among hot Jupiters. We estimate that this is consistent, however, with the circularization timescale which is slightly larger than the age of the system. These two hot Jupiters are both prime candidates for further characterization --- in particular, both are excellent candidates for determining spin-orbit alignments via the Rossiter-McLaughlin (RM) effect and for characterizing atmospheric thermal structures using secondary eclipse observations considering they are both located closely to the James Webb Space Telescope (JWST) Continuous Viewing Zone (CVZ).
