description: Serverless computing has seen rapid adoption due to its high scalability and flexible, pay-as-you-go billing model. In serverless, developers structure their services as a collection of functions, sporadically invoked by various events like clicks. High inter-arrival time variability of function invocations motivates the providers to start new function instances upon each invocation, leading to significant cold-start delays that degrade user experience. To reduce cold-start latency, the industry has turned to snapshotting, whereby an image of a fully-booted function is stored on disk, enabling a faster invocation compared to booting a function from scratch. This work introduces vHive, an open-source framework for serverless experimentation with the goal of enabling researchers to study and innovate across the entire serverless stack. Using vHive, we characterize a state-of-the-art snapshot-based serverless infrastructure, based on industry-leading Containerd orchestration framework and Firecracker hypervisor technologies. We find that the execution time of a function started from a snapshot is 95% higher, on average, than when the same function is memory-resident. We show that the high latency is attributable to frequent page faults as the function's state is brought from disk into guest memory one page at a time. Our analysis further reveals that functions access the same stable working set of pages across different invocations of the same function. By leveraging this insight, we build REAP, a light-weight software mechanism for serverless hosts that records functions' stable working set of guest memory pages and proactively prefetches it from disk into memory. Compared to baseline snapshotting, REAP slashes the cold-start delays by 3.7x, on average.

description: Cross-correlation between magnetism and dielectric is expected to offer novel emergent phenomena. Here, magnetic excitations in the organic donor-acceptor spin-chain system, TTF-BA, with a ferroelectric ground state is investigated by $^1$H-NMR spectroscopy. A nonmagnetic transition with a ferroelectric order is marked by sharp drops in NMR shift and nuclear spin relaxation rate $T_1^{-1}$ at 53 K. Remarkably, the analyses of the NMR shift and $T_1^{-1}$ dictate that the paramagnetic spin susceptibility in TTF-BA is substantially suppressed from that expected for the 1D Heisenberg spins. We propose that the spin-lattice coupling and the ferroelectric instability cooperate to promote precursory polar singlet formation in the ionic spin system with a nonmagnetic ferroelectric instability.

description: Marginally unstable Holmboe modes for smooth density and velocity profiles are studied. For a large family of flows and stratification that exhibit Holmboe instability, we show that the modes with phase velocity equal to the maximum or the minimum velocity of the shear are marginally unstable. This allows us to determine the critical value of the control parameter R (expressing the ratio of the velocity variation length scale to the density variation length scale) that Holmboe instability appears R=2. We then examine systems for which the parameter R is very close to this critical value. For this case we derive an analytical expression for the dispersion relation of the complex phase speed c(k) in the unstable region. The growth rate and the width of the region of unstable wave numbers has a very strong (exponential) dependence on the deviation of R from the critical value. Two specific examples are examined and the implications of the results are discussed.

Evaluation of new iterative and rebinning reconstruction algorithms in fully three-dimensional positron emission tomography
Creators: name: Krzywinski, Martin
Publisher: name: University of British Columbia
Year: 2009

description: An evaluation of new reconstruction algorithms for 3D positron emission tomography is presented. Using phantom and patient data, the standard 3D filtered backprojection algorithm is used to assess the merits of faster alternatives to full 3D reconstructions: FORE + 2D FBP, FORE + OSEM and FORE + SAGE. The phantom figures of merit that are used to evaluate these new algorithms are: resolution, noise, contrast recovery, signal-to-noise ratio, image uniformity and time activity curve variability. Using patient scans, the images are compared to 3D FBP reconstructions by examining the differences in radial profiles, region of interest activity, image root-mean-square, Logan slopes and computational demands. Both phantom and patient data analysis indicates that FORE + 2D FBP performs equally well as 3D FBP in terms of all figures of merit examined, with the exception that image uniformity and time activity curve variability are better than for 3D FBP. One clear benefit in using FORE .+ 2D FBP is that reconstruction is 10 times faster than 3D FBP. Based on the results obtained 3D FBP can be replaced by FORE + 2D FBP with no significant impact on subsequent analysis. Distribution volume ratios obtained with FORE + 2D FBP were different from 3D FBP results by 0.2 ± 0.4 % for cortical input function and —1.5 ± 0.4 % for cerebellar input function. Both OSEM and SAGE performed well, with increased resolution and distribution volume differences being < 3% for either input function.
A Historical Method Approach to Teaching Kepler's 2nd law

description: Kepler's 2nd law, the law of the areas, is usually taught in passing, between the 1st and the 3rd laws, to be explained "later on" as a consequence of angular momentum conservation. The 1st and 3rd laws receive the bulk of attention; the 1st law because of the paradigm shift significance in overhauling the previous circular models with epicycles of both Ptolemy and Copernicus, the 3rd because of its convenience to the standard curriculum in having a simple mathematical statement that allows for quantitative homework assignments and exams. In this work I advance a method for teaching the 2nd law that combines the paradigm-shift significance of the 1st and the mathematical proclivity of the 3rd. The approach is rooted in the historical method, indeed, placed in its historical context, Kepler's 2nd is as revolutionary as the 1st: as the 1st law does away with the epicycle, the 2nd law does away with the equant. This way of teaching the 2nd law also formulates the "time=area" statement quantitatively, in the way of Kepler's equation, M = E - e sin E (relating mean anomaly M, eccentric anomaly E, and eccentricity e), where the left-hand side is time and the right-hand side is area. In doing so, it naturally paves the way to finishing the module with an active learning computational exercise, for instance, to calculate the timing and location of Mars' next opposition. This method is partially based on Kepler's original thought, and should thus best be applied to research-oriented students, such as junior and senior physics/astronomy undergraduates, or graduate students.

description: Anomaly detection systems aim to detect and report attacks or unexpected behavior in networked systems. Previous work has shown that anomalies have an impact on system performance, and that performance signatures can be effectively used for implementing an IDS. In this paper, we present an analytical and an experimental study on the trade-off between anomaly detection based on performance signatures and system scalability. The proposed approach combines analytical modeling and load testing to find optimal configurations for the signature-based IDS. We apply a heavy-tail bi-modal modeling approach, where "long" jobs represent large resource consuming transactions, e.g., generated by DDoS attacks; the model was parametrized using results obtained from controlled experiments. For performance purposes, mean response time is the key metric to be minimized, whereas for security purposes, response time variance and classification accuracy must be taken into account. The key insights from our analysis are: (i) there is an optimal number of servers which minimizes the response time variance, (ii) the sweet-spot number of servers that minimizes response time variance and maximizes classification accuracy is typically smaller than or equal to the one that minimizes mean response time. Therefore, for security purposes, it may be worth slightly sacrificing performance to increase classification accuracy.

These substituent centers are proved to be an effective probe of the spin incommensurability and magnetic field effects.

description: Halo coronal mass ejections (HCMEs) originating from regions close to the center of the Sun are likely to be responsible for severe geomagnetic storms. It is important to predict geo-effectiveness of HCMEs using observations when they are still near the Sun. Unfortunately, coronagraphic observations do not provide true speeds of CMEs due to the projection effects. In the present paper, we present a new technique allowing estimate the space speed and approximate source location using projected speeds measured at different position angles for a given HCME (velocity asymmetry). We apply this technique to HCMEs observed during 2001-2002 and find that the improved speeds are better correlated with the travel times of HCMEs to Earth and with the magnitudes ensuing geomagnetic storms.

description: Synaptic vesicle (SV) exocytosis mediating neurotransmitter release occurs spontaneously at low intraterminal calcium concentrations and is stimulated by a rise in intracellular calcium. Exocytosis is compensated for by the reformation of vesicles at plasma membrane and endosomes. Although the adaptor complex AP-3 was proposed to be involved in the formation of SVs from endosomes, whether its function has an indirect effect on exocytosis remains unknown. Using mocha mice, which are deficient in functional AP-3, we identify an AP-3-dependent tetanus neurotoxin-resistant asynchronous release that can be evoked at hippocampal mossy fiber (MF) synapses. Presynaptic targeting of the tetanus neurotoxin-resistant vesicle soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) tetanus neurotoxin-insensitive vesicle-associated membrane protein (TI-VAMP) is lost in mocha hippocampal MF terminals, whereas the localization of synaptobrevin 2 is unaffected. In addition, quantal release in mocha cultures is more frequent and more sensitive to sucrose. We conclude that lack of AP-3 results in more constitutive secretion and loss of an asynchronous evoked release component, suggesting an important function of AP-3 in regulating SV exocytosis at MF terminals.

description: INTRODUCTION: Medulloblastoma is the most common malignant brain tumor in children and adolescents (20% of patients). Its treatment involves the use of surgery, radiotherapy (RT) and chemotherapy (CHT).

OBJECTIVE: To report a case of a teenage girl, 13, who developed severe neurological deficits three years after completion of treatment for medulloblastoma. CASE

REPORT: The patient was admitted to the service at nine years old, in August 2010, with neck pain, gait disturbance, diplopia and behavioral changes. Computed tomography scan revealed a mass in the posterior fossa. Partial resection was performed in September 2010, still remaining a radiologically-proven residual lesion of 3.5 × 3 cm. She did not have metastases at diagnosis. Histopathological examination revealed a desmoplastic medulloblastoma. She underwent CHT as per SOBOPE 93 protocol between November 2010 and April 2011. She was then sent to RT, being irradiated with a 5400 cGy dose (3600 cGy in neuraxis and an additional 1800 cGy boost to posterior fossa). Magnetic resonance imaging (MRI) in September 2011 did not show residual lesions. She was followed up with serial images until June 2014, when she presented with seizures, right hemiplegia, aphasia, and dysphagia. A MRI revealed left cortical atrophy, bleeding and vascular changes. MR Angiography confirmed occlusion / dissection in various branches of the left internal carotid artery.

DISCUSSION: The treatment for medulloblastoma is based on multimodality approach and patients with residual lesions greater than 1.5 cm postoperatively are classified as high risk. There is still no standard treatment for this high risk patient group. The RT dose administered ranges from 5400 to 5580 cGy cGy in the primary tumor area. The CHT schemes vary and may be pre- or post RT. Despite its importance, the RT is associated with high morbidity and complications. The curative doses are close to the neurotoxic doses. The main complications are damage to the white matter (diffuse leukoencephalopathy, radionecrosis), vascular damage (vascular disorders of small, medium and large vessels, including vascular malformations, and acute hemorrhage), second cancers, among others.

CONCLUSION: In the face of a late neurological deterioration in patients treated for medulloblastoma, one should consider vasculopathy related to RT as a differential diagnosis.

description: A finitely presented group is weakly geometrically simply connected (wgsc) if it is the fundamental group of some compact polyhedron whose universal covering is wgsc i.e. it has an exhaustion by compact connected and simply connected sub-polyhedra. We show that this condition is almost-equivalent to Brick's qsf property, which amounts to finding an exhaustion approximable by finite simply connected complexes, and also to the tame combability introduced and studied by Mihalik and Tschantz. We further observe that a number of standard constructions in group theory yield qsf groups and analyze specific examples. We show that requiring the exhaustion be made of metric balls in some Cayley complex is a strong constraint, not verified by general qsf groups. In the second part of this paper we give sufficient conditions under which groups which are extensions of finitely presented groups by finitely generated (but infinitely presented) groups are qsf. We prove, in particular, that the finitely presented HNN extension of the Grigorchuk group is qsf.

description: We compare the experimental data of the first measurement of a temperature dependence of the Casimir-Polder force by Obrecht et al. [Phys. Rev. Lett. {\bf 98}, 063201 (2007)] with the theory taking into account small, but physically real, static conductivity of the dielectric substrate. The theory is found to be inconsistent with the data. The conclusion is drawn that the conductivity of dielectric materials should not be included in the model of the dielectric response in the Lifshitz theory. This conclusion obtained from the long separation measurement is consistent with related but different results obtained for semiconductors and metals at short separations.

The study is specifically, about the use of culture in the conduct of foreign affairs and the attempt at approaching foreign societies, with the purpose of shaping public opinion. The campaign of ideological propaganda of the USA begins from the First World War and continues till nowadays. Considering the historical period, the campaign was addressed to differing target groups. After September 11, it is particularly, addressed to the islamic world. The neoliberal expansionist policy of the USA is accompanied by an equivalent campaign in terms of culture, which aims at establishing the supremacy of the american system of values, as well as at distracting consent, with the use of non military terms, for the world, wide political, economic, and cultural prevalence of the USA

description: Shock heating by radio jets is potentially an important process in a range of environments, as it will increase the entropy of the heated gas. Although this process is expected to occur in the most powerful radio-loud AGN, strong shocks have so far only been detected in nearby low-power radio galaxies. Here we discuss X-ray detections of strong shocks in nearby galaxies, including a new detection of shocked gas around both lobes of the nearby radio galaxy NGC 3801 with inferred Mach numbers of 3 - 6 and a total injected energy comparable to the thermal energy of the ISM within 11 kpc. We discuss possible links between shock heating, AGN fuelling and galaxy mergers and the role of this type of system in feedback models.

description: This study quantifies the amount of carbon stored and sequestered by vegetation in west Africa, carbon loss due to tree cover loss, and the potential natural sequestration relative to projected carbon emissions in 2030. GIS analysis of published data on vegetation biomass, tree cover, sequestration by vegetation and soil carbon indicate that vegetation and soil held 38,855 Mt of carbon in 2010, most of which was in above and below ground vegetation. The loss of 58,353 km2 (9%) of tree cover between 2010 and 2018 resulted in the loss of 672 Mt of 14,923 Mt carbon in vegetation. Key Biodiversity Areas, (sites of conservation importance), covered 7.4% of land but in 2010 contained 16% of carbon stored in vegetation. Trees sequestered between 23.6 and 53.6 Mt of carbon in 2018 (17% of which was in Key Biodiversity Areas). Restoration of the tree cover lost in west Africa between 2010 and 2018 could sequester an additional 27.5 Mt of carbon per annum during the first 30 years of growth. Our estimates indicate a combination of conservation and restoration of tree cover could sequester the equivalent of c.30% of projected 2030 regional emissions, contributing significantly towards mitigating climate change.

description: Many problems in physics, biology, and economics depend upon the duration of time required for a diffusing particle to cross a boundary. As such, calculations of the distribution of first passage time, and in particular the mean first passage time, is an active area of research relevant to many disciplines. Exact results for the mean first passage time for diffusion on simple geometries, such as lines, discs and spheres, are well--known. In contrast, computational methods are often used to study the first passage time for diffusion on more realistic geometries where closed--form solutions of the governing elliptic boundary value problem are not available. Here, we develop a perturbation solution to calculate the mean first passage time on irregular domains formed by perturbing the boundary of a disc or an ellipse. Classical perturbation expansion solutions are then constructed using the exact solutions available on a disc and an ellipse. We apply the perturbation solutions to compute the mean first exit time on two naturally--occurring irregular domains: a map of Tasmania, an island state of Australia, and a map of Taiwan. Comparing the perturbation solutions with numerical solutions of the elliptic boundary value problem on these irregular domains confirms that we obtain a very accurate solution with a few terms in the series only. Matlab software to implement all calculations is available on GitHub.

description: Αντικείμενο της διατριβής ήταν η μελέτη του θεσμού της ανατροπής κατάσχεσης, όπως αυτός οριοθετείται από τη διάταξη του άρθρου 1019 ΚΠολΔ. Εξετάσαμε τον δικαιολογητικό σκοπό και το πεδίο εφαρμογής του θεσμού, ενώ έγινε μία αντιπαραβολή αυτού από άλλους συναφείς θεσμούς του δικαίου της αναγκαστικής εκτέλεσης. Στη συνέχεια παρουσιάσαμε αναλυτικά τις προϋποθέσεις, οι οποίες ενεργοποιούν την ανατροπή κατάσχεσης, αφενός μεν για την περίπτωση της μη διενέργειας πλειστηριασμού εντός του νόμιμου χρόνου, αφετέρου δε για την περίπτωση της μη διενέργειας αναπλειστηριασμού εντός του νόμιμου χρόνου. Ακόμη, αναφερθήκαμε εκτενώς στα διαδικαστικά ζητήματα που άπτονται της ανατροπής κατάσχεσης, ήτοι στην ενεργητική και παθητική νομιμοποίηση, το έννομο συμφέρον, την αρμοδιότητα και την τηρητέα διαδικασία καθώς και τη δικαστική απόφαση που διατάσσει την ανατροπή. Ένα άλλο θέμα που θίξαμε ήταν οι έννομες συνέπειες που επιφέρει η απαγγελία της ανατροπής και ο χρόνος επέλευσης αυτών. Τέλος, ασχοληθήκαμε με τη θεματική της ανατροπής κατάσχεσης ειδικά ως προς τους αναγγελμένους με εκτελεστό τίτλο δανειστές και κλείσαμε την εργασία με ορισμένες διαπιστώσεις ως προς την συνύπαρξη του θεσμού με τη νομοθετική κατασκευή των πολλαπλών κατασχέσεων.
description: The subject of the thesis was the study of the institution of the reversal of seizure, as it is defined by the provision of article 1019 of the CCPD. We examined the justificatory purpose and the scope of application of the institution, while a comparison was made between it and other related institutions of the law of enforcement. We then presented in detail the conditions that trigger the reversal of seizure, on the one hand, in the case of failure to hold an auction within the statutory period, and on the other hand, in the case of failure to hold a re-auction within the statutory period. Furthermore, we have dealt extensively with the procedural issues relating to the reversal of an attachment, namely active and passive legitimacy, legal interest, jurisdiction and the procedure to be followed, as well as the court decision ordering the reversal. Another issue we touched upon was the legal consequences of the order of reversal and the time when they occur. Finally, we dealt with the subject of the reversal of attachment specifically with regard to creditors announced with an executory title and we concluded the paper with some observations as to the coexistence of the institution with the legislative construction of multiple attachments.

description: Introduction: Candidiasis and HIV co-infection may cause increased patient morbidity and mortality due to oropharyngeal or systemic dissemination. Limited information exists on the prevalence, antifungal susceptibility profiles and drug resistance mechanisms of Candida species on the African continent, the highest HIV-affected region globally and home to new and emerging drug resistant Candida species.

Methods: Candida species isolated from the oral mucosa of HIV-positive African patients were found to be resistant to many of the antifungals routinely used in HIV-associated candidiasis. Candida cell membrane fractions were examined using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and high performance liquid chromatography mass spectrometry (HPLC/MS) in order to elucidate the cell membrane proteins specifically expressed by antifungal drug resistant isolates.

Results: SDS-PAGE and HPLC/MS allowed for the identification of multi-drug resistance efflux transporter CDR2 proteins and the elucidation of Candida colonization mechanisms and pH-responsive proteins, with significant associations observed between specific drug resistance and the duration of antiretroviral (ARV) therapy.

Conclusion: This study provided useful information on the mechanisms of antifungal resistance in Candida species. It also formed the basis for further studies to address the transfer of resistance between Candida species in an oral microbial biofilm.

description: Manual static chamber is one of the most widespread methods for the quantification of greenhouse gases (GHGs) emissions from agricultural systems. But there are concerns about the reliability of measurements and a necessity to assess the static chambers used in the studies performed in the countries of Latin America. Thus, this study aims to investigate the quality of the characteristics from the static chamber methodology, the confidence level of the GHG measurements, and recommend what should be improved. We conducted a systematic review of databases to identify peer-reviewed articles that used the static chamber method in Latin America. A total of 90 articles were analyzed and separated according to the publication year (2000-2008, 2009-2015, 2016-2020). We evaluated eight design and deployment chamber characteristics. The depth of base insertion and type of storage vial received the lowest scores, and the number of samples received the highest score. The description and reporting of the methodological procedures in the studies should be improved. The percentage of articles with high and medium confidence levels increased within the time, and the number of articles with low and very low confidence levels reduced. Scientists/Researchers should continue to follow the protocols, especially the most updated ones.

description: Replicability and reproducibility of experimental results are primary concerns in all the areas of science and IR is not an exception. Besides the problem of moving the field towards more reproducible experimental practices and protocols, we also face a severe methodological issue: we do not have any means to assess when reproduced is reproduced. Moreover, we lack any reproducibility-oriented dataset, which would allow us to develop such methods. To address these issues, we compare several measures to objectively quantify to what extent we have replicated or reproduced a system-oriented IR experiment. These measures operate at different levels of granularity, from the fine-grained comparison of ranked lists, to the more general comparison of the obtained effects and significant differences. Moreover, we also develop a reproducibility-oriented dataset, which allows us to validate our measures and which can also be used to develop future measures.

description: The hard X-ray source IGRJ11215-5952, discovered with INTEGRAL during a brief outburst in 2005, has been proposed as a new member of the class of Supergiant Fast X-ray Transients. Analysing archival INTEGRAL observations of the source field,we have discovered two previously unnoticed outbursts (in July 2003 and in May 2004),spaced by intervals of ~330 days, suggesting a possible orbital period.The 5-100keV spectrum is well described by a cut-off power law, with a photon index of 0.5, and a cut-off energy 15-20keV, typical of High Mass X-ray Binaries containing a neutron star. The luminosity is ~3E36erg/s assuming 6.2kpc, the distance of the likely optical counterpart, the blue supergiant HD306414.A fourth outburst was discovered in 2006 with XTE/PCA, 329 days after the third one, confirming the periodic nature of the source outbursts.Follow-up observations with Swift/XRT refined the source position and confirmed the association with HD306414.The 5-100keV spectrum, the recurrent nature of the outbursts, the blue supergiant companion star HD 306414, support the hypothesis that IGRJ11215-5952 is a Supergiant Fast X-ray Transient, and it is the first object of this class of High Mass X-ray Binaries displaying periodic outbursts.

description: We review models for the nucleation of magnetisation reversal, i.e. the formation of a region of reversed magnetisation in an initially magnetically saturated system. For small particles models for collective reversal, either uniform (Stoner-Wohlfarth model) or non-uniform like curling, provide good agreement between theory and experiment. For microscopic objects and thin films, we consider two models, uniform (Stoner-Wohlfarth) reversal inside a nucleation volume and a droplet model, where the free energy of an inverse bubble is calculated taking into account volume energy (Zeeman energy) and surface tension (domain wall energy). In macroscopic systems, inhomogeneities in magnetic properties cause a distribution of energy barriers for nucleation, which strongly influences effects of temperature and applied field on magnetisation reversal. For these systems, macroscopic material parameters like exchange interaction, spontaneous magnetisation and magnetic anisotropy can give an indication of the magnetic coercivity, but exact values for nucleation fields are, in general, hard to predict.

description: Under Article 6.2 of the Paris Agreement, countries have the option to use existing crediting schemes, including schemes serving voluntary carbon offset markets, as a basis for trading “mitigation outcomes”. Parties to the Paris Agreement engaged in such trading must seek to ensure its environmental integrity, an essential component of which is ensuring the quality of units (or “credits”) transacted. In deciding whether to rely on existing crediting schemes, therefore, countries must be able to assess the relative quality of the credits these schemes issue. Assessing unit quality can be a complex undertaking involving analysis at multiple levels (e.g. institutions, methodologies, and mitigation activities). An essential requirement, however, is for crediting schemes to have robust standards and practices in place for ensuring unit quality. This paper presents a framework for assessing the standards and practices of crediting schemes on aspects related to unit quality, and road tests this framework on six existing schemes. A key finding is that all six schemes have weaknesses in their standards and practices, suggesting the need for ongoing improvement as carbon market institutions continue to evolve under the Paris Agreement.
Measurement of proton beam dose profiles using a sensitive scintillation screen observed with a CCD camera

Publisher: name: University of British Columbia

description: The Proton Therapy Facility at TRIUMF has been in routine operation since 1995 using 70 MeV protons extracted from the 500 MeV H" cyclotron to treat ocular melanomas. The main rationale behind using proton therapy over conventional therapy is its improved conformity (i.e. manipulating the beam to deliver maximum dose to the tumour volume and minimum dose to the healthy surrounding tissue) and uniformity of dose delivery. Efforts have been made to develop a rapid method of measuring dose profiles using a sensitive scintillating screen observed by a CCD camera. The main advantage of this sort of dosimetry system is its ability to do near real-time observation and analysis of the proton beam; the system offers a practical and timesaving method of quality control. Conventional proton dosimetry methods, which consist of a miniature detector scanned in a water box, can be slow and impractical for some studies. Experiments have been carried out using beam energies and intensities well matched to clinical doses. A scintillating screen enclosed in a light tight box is placed in the path of the proton beam, and is observed by a CCD camera. The CCD camera, which views the screen through a 45-degree mirror has an integrating mode for increased sensitivity and a frame grabber for immediate viewing. Various commercial intensifying screens have been evaluated and one screen Rarex PFG (ZnCdS:Ag) has been found to be 17 times more sensitive than the more commonly used LANEX (Gd₂0₂S:Tb) screen. The system has demonstrated to be useful for rapid visualization of lateral dose distributions to look at collimator scattering, beam steering, raw Bragg peaks, and effect of wedges.

description: As exoplanetary science matures into its third decade, we are increasingly offered the possibility of pre existing, archival observations for newly detected candidates. This is particularly poignant for the TESS mission, whose survey spans bright, nearby dwarf stars in both hemispheres, which are precisely the types of sources targeted by previous radial velocity (RV) surveys. On this basis, we investigated whether any of the TESS Objects of Interest (TOIs) coincided with such observations, from which we find 18 single planet candidate systems. Of these, one exhibits an RV signature that has the correct period and phase matching the transiting planetary candidate with a false alarm probability of less than 1 percent. After further checks, we exploit this fact to validate HD 183579b (TOI-1055b). This planet is less than 4 Earth Radii and has better than 33 percent planetary mass measurements, thus advancing the TESS primary objective of finding 50 such worlds. We find that this planet is amongst the most accessible small transiting planets for atmospheric characterization. Our work highlights that the efforts to confirm and even precisely measure the masses of new transiting planet candidates need not always depend on acquiring new observations - that in some instances these tasks can be completed with existing data.
