Non-Contact, Optical Forearm Venous Occlusion Plethysmography
Creators: name: Voos, Ian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The gold standard method for determining forearm blood flow in clinical trials for cardiovascular drugs, known as forearm blood-flow (FBF) plethysmography, has not changed in over 60 years1. This technique provides a simple metric for estimating forearm blood flow by monitoring changes in forearm circumference over the time. The present study improves the current method with a dual, non-contact, near infrared imaging (NIR) system using both the Microsoft Kinect V2 (Microsoft Corporation, 2013) and the Raspberry Pi (Raspberry Pi Foundation, 2016) with Pi NoIR cameras. These cameras use NIR light for enhanced acquisition of sub-dermal, vascular information. This has the opportunity to improve the safety of cardiovascular drugs, as it can provide researchers with more information, like pulse wave velocity and perfusion, about the underlying vascular. The results of this experiment show that significant differences exist between both the pixel length of the images and the amplitude of the strain gauge voltage before and after occlusion (p<0.0001). These results are important, as they suggest that the data from the images correlates with the current platinum standard in forearm plethysmography.

description: We consider the continuous-variable protocol of Pirandola et al. [Nature Photonics 9, 397-402 (2015), see also arXiv.1312.4104] where the secret-key is established by the measurement of an untrusted relay. In this network protocol, two authorized parties are connected to an untrusted relay by insecure quantum links. Secret correlations are generated by a continuous-variable Bell detection performed on incoming coherent states. In the present work we provide a detailed study of the symmetric configuration, where the relay is midway between the parties. We analyze symmetric eavesdropping strategies against the quantum links explicitly showing that, at fixed transmissivity and thermal noise, two-mode coherent attacks are optimal, manifestly outperforming one-mode collective attacks based on independent entangling cloners. Such an advantage is shown both in terms of security threshold and secret-key rate.

Victor Hugo and the Politics of Masculinity, Representations of Nineteenth-Century French Virility in Les Châtiments (1853)
Creators: name: Jacobs, Michael P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: This thesis demonstrates how 19th-century French author Victor Hugo used
masculinity as a trope to illustrate the sociopolitical destruction of France under the
Second Empire of Napoleon III. Using Hugo’s collection of poems in Les Châtiments
(1853) as the primary point of inquiry, analysis of his literary work and political
interventions shows how the author depicted Louis-Napoleon Bonaparte as a tyrant
whose tenure as Emperor precipitated the destruction of France’s national sense of
virility. Hugo in turn, I contend exhorts the French people to recuperate their virility in
order to reject Napoleon III. Furthermore, I examine the historical relationship between
Napoleon III and his uncle, Napoleon I, and how Napoleon III’s appropriation of the
symbolism that characterized Napoleon I allowed Hugo to emasculate Napoleon III for
representing the antithesis to his uncle’s likeness. Finally, this thesis explores how
Hugo’s literature and political activism revirilized France at the beginning of the Third
Republic.

description: The aim of this research has been to explore what is understood about collaborative online learning with a view to identifying the features necessary to design a collaborative online mathematics homework system that supports a partnership between Year 1 teachers, parents, and students. This research has been guided by an epistemological framework within a pragmatic paradigm. Qualitative data was recorded through face-to-face paired depth interviews with teachers in their classrooms at their schools. Themes within the data were identified using Reflexive Thematic Analysis. Outputs include a description of participant experiences, teacher-parent-student relationship description, and a feature description. Contributions include insights to how participants currently connect online, their adherence to the Australian Curriculum, and how collaboration could be supported. Discussion includes identification of sixteen features demarcated into: eight features for a learning objective interface; and eight features to improve teacher/parent trust. Two main barriers were identified that could prevent effective integration of the required features and recommendations proposed to overcome those barriers to design a collaborative online homework system for Year 1 mathematics.

Reductive N-heterocycle and carbocycle formation under R3SiH-B(C6F5)3 catalysis
Creators: name: Zhong, Hongyu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Based on our group’s previous study on chemoselective partial reduction of
silyl-protected sugars and sugar-derivatives1, a diverse set of oxygen-functionalized chiral
synthons can be synthesized in short steps. The catalytic combination of the strong Lewis acid
B(C6F5)3 and a tertiary silane efficiently generates a reactive equivalent of an highly
electrophilic silylium ion (R3Si+) and a HB(C6F5)3
- reducing agent2. The silylium ion
“activates” the C-O bond through a favored formation of the strong Si-O bond, pulling
electron density from the oxygen atom and weakening the C-O bond. The hydride is delivered
by HB(C6F5)3
- to attack the carbon atom and break the C-O bond in an SN2 fashion. The
catalytic reduction of C-O bonds allows control for stereo-selectivity and site-selectivity in an
array of stereo-defined C-O bonds that are ubiquitous in carbohydrates, achieved by
mechanism of neighboring group participation and formation of cyclic intermediates.
It has been shown that with low concentration or absence of the reducing species
HB(C6F5)3
-, intramolecular nucleophilic attack by oxygen lone pair outcompetes
intermolecular hydride attack. The resulting O-heterocycle products can be isolated. As
heterocycles are common components of various natural products and drugs3a-3c, we continued
to explore the formation of heterocycles and even carbocycles using sugar derivatives, which
are naturally abundant chiral pool compounds and building-blocks for total synthesis4. In our
study, when amine moiety and alkene moiety are incorporated into carbohydrate molecules,
the N lone pair and C=C bond act as nucleophiles to achieve intramolecular cyclization.
Starting from the bio-renewable enantiopure chiral pool compounds as an alternative for fossil
fuels5, the catalytic combination of R3SiH-B(C6F5)3 enables generation of pharmaceutical
precursors containing heterocycle and carbocycle cores in high diastereoselectivity.

description: The photo captured in 2018 during a one-week stopover on a trip between two Central Rainforest regions of Peru is the point of departure for a reflection on the use of sound by Asháninka, Nomatsiguenga, and other rainforest peoples for “Amasonic” politics. A wide span of genres ranging from autochthonous songs produced by ensembles playing percussions and pan-flutes to school bands performing military marches is key when rainforest peoples exert pressure in the provincial capital to obtain land titles and other rights. Asháninka and Nomatsiguenga leaders also create soundscapes pervaded by politics at local gatherings to consume manioc beer and ally with supporters to enhance their demands. Disputes take place within these shared soundscapes, as evidenced by a Mother's Day celebrations at which Indigenous and nonindigenous school teachers chose diverging music and dances for their grades to perform because of disagreement about what is essential for the Peruvian repertoire.

description: Field experiments are subjected to spatial variability due to factors such as soil moisture, fertility, pH, and structure, as well as the pressure of diseases and pests. Soybean yields are highly variable across fields. Controlling spatial variability could decrease the risk of erroneous inferences in breeding trials. This study aims at evaluating the spatial variability of furrow-irrigated soybean for seed yield, wilting, and maturity under four different irrigation levels. The field experiment was conducted in four environmzents (location-year combination). A total of 165 soybean lines of similar relative maturity (maturity group 5) along with commercial checks were planted in an augmented strip plot design. Irrigation treatment decisions were triggered using an atmometer based on a threshold at a designated growth stage. Data were analyzed via Analysis of Variance as a linear mixed model using a blocking structure (block model) and spatial covariances using range and column. Two different spatial models were used: exponential and Gaussian. Results showed that the spatial models displayed better data fitting (lower AIC and/or BIC) than the block model in each different irrigation level across different environments and traits. Indeed, genotype ranking for seed yield was different between the block model and the best spatial model, suggesting that spatial adjustment may be necessary for soybean breeding operations under furrow irrigation. Further validation in a breeding yield trial demonstrated similar results of the effectiveness in terms of AIC and/or BIC of the spatial model compared to the block model for soybean seed yield.

description: The primary sequence of a biopolymer encodes the essential information for folding, permitting to carry out sophisticated functions. Inspired by natural biopolymers, peptide and nucleic acid sequences have been designed to adopt particular three-dimensional (3D) shapes and programmed to exert specific functions. In contrast, synthetic glycans capable of autonomously folding into defined 3D conformations have so far not been explored owing to their structural complexity and lack of design rules. Here we generate a glycan that adopts a stable secondary structure not present in nature, a glycan hairpin, by combining natural glycan motifs, stabilized by a non-conventional hydrogen bond and hydrophobic interactions. Automated glycan assembly enabled rapid access to synthetic analogues, including site-specific 13C-labelled ones, for nuclear magnetic resonance conformational analysis. Long-range inter-residue nuclear Overhauser effects unequivocally confirmed the folded conformation of the synthetic glycan hairpin. The capacity to control the 3D shape across the pool of available monosaccharides has the potential to afford more foldamer scaffolds with programmable properties and functions.

description: Wild boar is increasingly establishing populations in the outskirts of European cities, with the largest German urban population occurring in Berlin. Related soil disturbance in grasslands is common and often considered as damage to biodiversity. However, it is unknown how animal and plant species in urban grasslands respond to wild boar activity - an important limitation for conservation management. We sampled plants, grasshoppers and sand lizards in 22 dry grasslands and measured wild boar activity. We show that plant diversity decreased with rooting intensity, but not species richness, endangered or specialist species. Relationships with animals were mostly positive. Grasshopper diversity, total richness and richness of endangered and specialist species were positively related to rooting, as was sand lizard abundance. These relationships contrast to mostly negative effects in the wild boar’s non-native range. This first multi-taxa study in a large city suggests that soil disturbance by wild boars is not necessarily a threat to biodiversity. An implication for conservation is to consider the context-dependence of biodiversity responses to wild boar activity. For dry grasslands, disturbed patches should be accepted in management plans rather than re-vegetated by seeding.
Temperature effects on the carbon content of marsh sediment measured through time using a CHN elemental analyzer and loss on ignition
Creators: name: Atencio, Anna Nicole
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Within the last decade, interest in conserving and restoring saltmarsh for their ability to
rapidly sequester, and bury carbon has increased; however, the methodology for carbon analysis
in marsh cores has not been standardized. Unless marsh sediment is dried or frozen after
sampling, the carbon fraction is subject to microbial degradation through time. In this paper, we
examine how saltmarsh-core storage temperature affects the carbon content of subsamples
through time. We also compare CHN elemental analysis to loss on ignition (LOI) for measuring
marsh carbon and organic matter, respectively. We used a marsh core from French Creek, NC,
U.S.A, and extracted two 10-cm long sections from the upper and lower part of the core. These
sections were mechanically homogenized and placed in 3 different temperature locations
including: 1) a freezer at -20°C, 2) a refrigerator at 1.5°C, and 3) an indoor lab at 24°C. We
subsampled each core section 9 times over 128 days for analysis of percent carbon (elemental
analyzer) and percent organic matter (LOI). The upper part of the core had an initial value of
28.5 ± 2.2 % organic carbon and 57.1 ± 0.2 % organic matter, and the lower part had an initial
value of 39.2 ± 5.9 % organic carbon and 77.6 ± 0.2 % organic matter. These results are in line
with average carbon and organic matter content for saltmarshes in the area. We found that the
carbon content of saltmarsh cores stored at temperatures below 24°C does not steadily decrease
at a level below the resolution of our method (average standard deviation of 1.9%). Similarly, no
decrease in organic matter below 0.45% (average standard deviation of the LOI analyses) was
observed. CHN analysis introduces more uncertainty in measurements than LOI, which is likely
due to incomplete sample homogenization, which is difficult to overcome. The LOI method uses
an order of magnitude larger subsample than an elemental analyzer and when percent organic
matter is converted to percent carbon using the conversion equation from Craft et al. (1991) it
allows for a more accurate and precise measurement when complete sample homogenization
cannot be confirmed.

description: Managerial practices for farming-system intensification have received increased focus in research-and-development (R&D) initiatives. These technologies are proven to close the yield gaps in researcher-managed field trials and are recommended for farmer’s adoption. However, not all farmers have the technical, financial, and social capital to adopt and benefit from these recommended technologies. Is the current level of productivity enhancement achieved by smallholder system intensification sufficient to sustain rural livelihoods? To this end, the study assessed the impacts of hybrid maize (Zea mays L.) adoption on productivity and livelihoods in the mid-hill region of Nepal. Smallholders in the study region face severe shortages of labor, improved cultivars, and inorganic fertilizers, resulting in very low yields and profitability. We find that maize hybrid adoption increased crop productivity by 109%, making the crop profitable for smallholders and enhancing the per capita food expenditure by 20%. Nevertheless, these benefits were unevenly distributed: relatively small farms (≤0.3 ha) achieved greater gains in productivity and livelihood per land unit from hybrid maize adoption, but only larger farms (>0.3 ha) enjoyed the aggregate livelihood benefits of the technology. System intensification gains economic relevance because of the severe scarcity of resources, whereas the resource scarcity itself determines the economic relevance of system intensification, presenting a paradox. Increasing market access to material inputs did not significantly alter the observed patterns. More studies are required on the relationship between farm size and the livelihood impacts of sustainable intensification to facilitate R&D targeting and ensure inclusive development.

description: Objectives: Evidence-based decision-making is the sine qua non for safe and effective patient care and the long-term functioning of health systems. Since 2020 Digital Health Applications (DiHA) in Germany have been undergoing a systematic pathway to be reimbursed by statutory health insurance (SHI) which is attracting attention in other European countries. We therefore investigate coverage decisions on DiHA and the underlying evidence on health care effects, which legally include both medical outcomes and patient-centred structural and procedural outcomes. Methods: Based on publicly available data of the Institute for Medicines and Medical Devices searched between 08/2021 and 02/2022, all DiHA listed in the corresponding registry and thus reimbursable by the SHI were systematically investigated and presented descriptively on the basis of predefined criteria, such as clinical condition, and costs. The clinical trials on DiHA permanently included in the registry were reviewed with regard to their study design, endpoints investigated, the survey instruments used, and whether an intention-to-treat analysis was performed. Risk of bias was assessed using the ROB II tool. Results: By February 2022, 30 DiHA had been included in the DiHA registry, one third of them permanently and two thirds conditionally. Most DiHA were therapeutic applications for mental illness based on cognitive behavioural therapy. For all permanently included DiHA, randomised controlled trials were conducted to demonstrate the impact on health care effects. While medical outcomes were investigated for all of these DiHA, patient-centred structural and procedural outcomes were rarely investigated. The majority of clinical trials showed a high risk of bias, mainly due to insufficient reporting quality. Overall, the prices for DiHA covered by SHI are on average around € 150 per month (min. € 40; max. € 248). Conclusions: Evidence-based decision-making on coverage of DiHA leaves room for improvements both in terms of reporting-quality and the use of patient-centred structural and procedural outcomes in addition to medical outcomes. With appropriate evidence, DiHA can offer an opportunity as an adjunct to existing therapy while currently the high risk of bias of the trials raises doubts about the justification of its high costs.

description: Finite-time coherent sets (FTCSs) are distinguished regions of phase space that resist mixing with the surrounding space for some finite period of time; physical manifestations include eddies and vortices in the ocean and atmosphere, respectively. The boundaries of FTCSs are examples of Lagrangian coherent structures (LCSs). The selection of the time duration over which FTCS and LCS computations are made in practice is crucial to their success. If this time is longer than the lifetime of coherence of individual objects then existing methods will fail to detect the shorter-lived coherence. It is of clear practical interest to determine the full lifetime of coherent objects, but in complicated practical situations, for example a field of ocean eddies with varying lifetimes, this is impossible with existing approaches. Moreover, determining the timing of emergence and destruction of coherent sets is of significant scientific interest. In this work we introduce new constructions to address these issues. The key components are an inflated dynamic Laplace operator and the concept of semi-material FTCSs. We make strong mathematical connections between the inflated dynamic Laplacian and the standard dynamic Laplacian, showing that the latter arises as a limit of the former. The spectrum and eigenfunctions of the inflated dynamic Laplacian directly provide information on the number, lifetimes, and evolution of coherent sets.

description: We conducted a cross-national study on antisemitic hate speech on the Facebook profiles of leading media outlets in the United Kingdom, France, and Germany. In a combination of qualitative pragmalinguistic analysis and quantitative analysis, we examined their comment sections concerning the conceptual and linguistic repertoire of verbal antisemitism in these three languages as well as to the frequency of antisemitic utterances. The corpus comprises 4500 comments (1500 for each language) made in reaction to the media’s Facebook posts reporting on an escalation phase of the Arab–Israeli conflict in May 2021. Since in antisemitism studies, Israel—and issues related to it—are widely perceived as today’s main pretext for communicating antisemitic resentment, unsurprisingly, those events led to the emergence of antisemitic content online. This article contrasts the findings of antisemitism in the three countries’ comment sections and illustrates them by presenting a variety of linguistic realisations of various antisemitic concepts and illustrates the corresponding steps of interpretation.

description: α-Amanitin is a bicyclic octapeptide composed of a macrolactam with a tryptathionine cross-link forming a handle. Previously, the occurrence of isomers of amanitin, termed atropisomers has been postulated. Although the total synthesis of α-amanitin has been accomplished this aspect still remains unsolved. We perform the synthesis of amanitin analogs, accompanied by in-depth spectroscopic, crystallographic and molecular dynamics studies. The data unambiguously confirms the synthesis of two amatoxin-type isomers, for which we propose the term ansamers. The natural structure of the P-ansamer can be ansa-selectively synthesized using an optimized synthetic strategy. We believe that the here described terminology does also have implications for many other peptide structures, e.g. norbornapeptides, lasso peptides, tryptorubins and others, and helps to unambiguously describe conformational isomerism of cyclic peptides.

description: We aim to contribute to recent situational approaches to the study of interpersonal violence by elaborating the concept of trajectories. Trajectories are communicative processes in which antagonists act upon each other’s bodily and verbal actions to project a direction for the interaction to take, which is then (con) tested in the exchanges that follow. We use the notion of trajectories to gain insight in how participants turn an antagonistic situation into a violent encounter, which we contrast to interactionist and micro-sociological understandings. Using ethnomethodological and conversation analytical tools, we detail the trajectories of three violent encounters, captured on phone camera recordings to answer the question how verbal and bodily exchanges project physical violence. Methodologically, our contribution shows how bodily actions can be studied in visual data. Our cases show how antagonists move the interaction toward violence by creating a metaconflict revolving around the conditions under which the interaction will become a physical confrontation; what we call the contested projection of violence. We conclude that the concept of trajectories offers a useful analytical tool to detail the shifts and turns of the interactive process—notably it’s bodily dimensions— that characterize antagonism and violence. Substantially, our analysis raises questions about conceptualizations of the emotional dynamics (notably the role of dominance) of violence, as proposed by earlier micro-sociological and interactionist work. We therefore suggest that future studies engage with these issues in more detail and in larger datasets.

description: Urban water security (UWS) is and will remain a crucial issue over the next decades, especially as it is exacerbated by climate change effects and related hazards. Despite the growing number of studies focusing on more diverse dimensions, including social dimensions, of water security and urban dynamics, there is still an absence of comprehensive, interdisciplinary UWS measurement index that takes into account the complexity and multidimensional aspects of water security. This article discusses a new, transdisciplinary community-focused approach to analyzing and responding to water insecurity. It draws on findings from a large study carried out over 4 years with a focus on creating a new and comprehensive way of measuring water security, incorporating biophysical and social factors. The project collected data in Kolkata, India. Kolkata is an important megacity in a developing country, facing rising pressures on water-environmental provision due to rapid population growth and urbanization combined with governance and infrastructural issues. The project team worked collaboratively with affected communities to create a comprehensive framework for measuring and evaluating water security for cities. A water justice approach to water security we argue is particularly important in emerging countries, and one that can be effectively applied to environments where urban growth and resultant shrinking resources have created complicated and fragile systems. This approach adds to existing knowledge and research that focuses on collaborative interdisciplinary methods that aim to create solutions that can help create a sustainable water secure future “leaving no one behind.”
Is Traditional Medicine a Normal Good? Traditional Medicine Use and Correlates in China

description: Despite the widespread use of Traditional Medicine (TM) in developing countries, many questions surrounding the nature of demand for TM remain unexplored. As one of the fundamental dimensions of China’s health care system, Traditional Chinese Medicine (TCM) has played a changing role as China’s economy has grown and political leaders have promoted TCM, however, very limited research explored the nature of the relative demand for TCM and CM to guide the health policy design and health system integration in current China.       To fill in this information gap, this study explored the nature of demand for TCM and the associations between wealth and TCM utilization using a nationally representative, longitudinal study in China. We described TCM and CM utilizations by demographics, chronic conditions and examined how TCM use varies with wealth employing OLS regressions. Heterogeneity in the association between wealth and TCM use was also tested. The study found that the TCM use prevalence was 28.7% and nearly 91% of the population who used TCM also used CM. TCM users were found to be older, female, less educated and more likely to have chronic conditions. The regression results revealed a positive relationship between wealth and TCM, which suggests that TCM is a normal good. We also found a stronger association between wealth and TCM in older population but no heterogeneity was found across people with different chronic conditions and education levels. In conclusion, our findings suggest that TCM is a normal good with the possibility of being demanded as a complement of CM, playing an important role in chronic conditions treatment in China.

description: The sound emission characteristics of unmanned aerial systems are of interest in many contexts. For a realistic representation of the directional characteristics and the radiated sound energy, it is useful if the aircraft is operated under realistic conditions. However, deriving emission-based acoustic quantities for a typical mode of operation such as cruise flight is difficult. In this paper, the directivity and sound power of a quadcopter drone are determined using a microphone array measurement of a single flight through a predefined corridor. The recorded data are processed to both reconstruct the drone’s flight path and characterize its acoustic emission. To verify the reliability of the presented method, the signal processing is tested with simulated data from moving sources with the directivity of a monopole as well as a dipole. Using different discretizations of the radiation direction space and evaluating the frequency-dependent directivity factor, it is discussed how the sound radiation can be described as comprehensively as possible on the basis of as few quantities as possible.

description: Electron-transport layers (ETLs) have a crucial role in the solar cells’ performance. Generally, ETLs are characterized in terms of the interface properties and conductivity rather than their effect on the photoactive layer. Herein, two ETLs, 2,9-bis(3-((3-(dimethylamino)propyl)amino)propyl)anthra[2,1,9-def:6,5,10-d′e′f′]diisoquinoline-1,3,8,10(2H,9H)-tetraone (PDINN) and 2,9-bis[3-(dimethyloxidoamino)propyl]anthra[2,1,9-def:6,5,10-d′e′f′]diisoquinoline-1,3,8,10(2H,9H)-tetrone, are compared in the conventional PM6:Y6 organic solar cell (OSC) structure and the influence of the ETL on the photoactive layer is shown. It is shown that a significant portion of the unpaired electrons of PDINN is mobile by combining electron paramagnetic resonance and Hall effect measurements. It is established that the high doping in PDINN ETL changes the dark electron concentration of the photoactive layer. The impacts of this change in the photoactive layer can be observed in the reduced static energetic disorder, and subsequently in the (nonradiative) recombination of free carriers. The results can be used to suppress nonradiative recombination in OSC, which can significantly boost their efficiency.

description: Elaphoglossum affine (M.Martens & Galeotti) T.Moore, Index Fil. 4. 1857. (Fig. 1A–C)
 Range: —Southern Mexico to Bolivia (CO, LP).
 Ecology: —Rare; saxicolous in humid forests and páramo vegetation; 2200–3600 m.
 Elaphoglossum ambiguum Mett. ex Christ ex Alston, J. Wash. Acad. Sci. 48: 234. 1958. (Fig. 44F–H).— Type: VENEZUELA. Aragua: Colonia Tovar. [ca. 10°25’N, 67°17’W] 1854/1856, A. Fendler 283 (lectotype B 20 0069755 [image 264287], here designated, isolectotypes BM, K-000501546, MO-255885, US, YU-000647).
 Range: — Costa Rica and Panama; Andes from Venezuela to Bolivia (CO, LP).
 Ecology: —Rare; epiphytic in humid forests; (650–) 1000–2250 m.
 Notes: —The costal hairs of this species can be difficult to find and costae may appear glabrous, while in E. papyraceum the hairs are tiny, but dense.
 The specific epithet ambiguum was first used by Mettenius for Fendler 283 at B; however, he did not publish the name. The name was first used in print by Christ (1899: 60) as an un-numbered name under Elaphoglossum flaccidum. On page 27 of that publication, he stated that un-numbered names are those he did not consider to be valid species, effectively making Acrostichum ambiguum an unpublished name, as also concluded by Rojas-Alvarado (2002). Alston (1958b), however, considered the species to be distinct and provided a combination in Elaphoglossum. Because he did not describe the species, the reference to Christ’s description serves to validate the name. Christ cited four specimens for the species: Fendler 283 (B), Gollmer s.n. (B), Moritz 235 (B), and Pittier 10536. We here designate Fendler 283 in B as the lectotype because it is a complete, fertile specimen with rhizome. Also, it was studied by both Mettenius and Christ, and the Fendler collection is well represented in other herbaria (Smith & Todzia 1989).

description: Using light to control transient phases in quantum materials is an emerging route to engineer new properties and functionality, with both thermal and non-thermal phases observed out of equilibrium. Transient phases are expected to be heterogeneous, either through photo-generated domain growth or by generating topological defects, and this impacts the dynamics of the system. However, this nanoscale heterogeneity has not been directly observed. Here we use time- and spectrally resolved coherent X-ray imaging to track the prototypical light-induced insulator-to-metal phase transition in vanadium dioxide on the nanoscale with femtosecond time resolution. We show that the early-time dynamics are independent of the initial spatial heterogeneity and observe a 200 fs switch to the metallic phase. A heterogeneous response emerges only after hundreds of picoseconds. Through spectroscopic imaging, we reveal that the transient metallic phase is a highly orthorhombically strained rutile metallic phase, an interpretation that is in contrast to those based on spatially averaged probes. Our results demonstrate the critical importance of spatially and spectrally resolved measurements for understanding and interpreting the transient phases of quantum materials.
