description: Dryodromya testacea Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 150.
TYPE LOCALITY: Rondani gave no type locality in his original description but presumably it is Italy because the work deals with Italian species.
TYPE MATERIAL: not found in this study.
CURRENT STATUS: valid species, as Dryodromia testacea (Chvála & Wagner 1989: 318, Pesarini et al. 1995: 12, Yang et al. 2007: 345).
REMARKS: Rondani’s (1856: 150) key for the genus Dryodromya Rondani, 1856 lists Dryodromya testacea as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. Rondani described this nominal species under the generic name Dryodromya, which is an “incorrect original spelling” of Dryodromia (O’Hara et al. 2011: 76). We could not locate any type specimens of this nominal species during our study.

description: This paper proposes a social account for the origin of the truth value and the emergence of the first declarative sentence. Such a proposal is based on two assumptions. The first is known as the social intelligence hypothesis: that the cognitive evolution of humans is first and foremost an adaptation to social demands. The second is the function-first approach to explaining the evolution of traits: before a prototype of a new trait develops and the adaptation process begins, something already existing is used for a new purpose. Applied to the emergence of declarative sentences (statements), this suggests something already existing––natural signs (such as indexical objects)––was used for the declarative function and thereby integrated into communication. I show that index display (such as the display of hunting trophies) can imply a conceptual structure similar to that informing the syntax of sentences. The view developed in this paper is broadly consistent with the argumentative theory of Mercier and Sperber, which suggests that reasoning is less adapted to decision making than to social purposes such as winning disputes. In this paper I extend this view to the evaluation of propositions expressed in declarative sentences. According to my proposal, the first declarative sentence emerged as the negation of the (implicit) negation of an implicit statement. Thereby, I suggest that the binary structure of the truth value underlying any declarative sentence is founded on disagreements based on conflicts of interests.
Double Shuffle Relations for Refined Symmetric Multiple Zeta Values

description: Symmetric multiple zeta values (SMZVs) are elements in the ring of all multiple zeta values modulo the ideal generated by $\zeta(2)$ introduced by Kaneko-Zagier as counterparts of finite multiple zeta values. It is known that symmetric multiple zeta values satisfy double shuffle relations and duality relations. In this paper, we construct certain lifts of SMZVs which live in the ring generated by all multiple zeta values and $2\pi i$ as certain iterated integrals on $\mathbb{P}^{1}\setminus\{0,1,\infty\}$ along a certain closed path. We call these lifted values refined symmetric multiple zeta values (RSMZVs). We show double shuffle relations and duality relations for RSMZVs. These relations are refinements of the double shuffle relations and the duality relations of SMZVs. Furthermore, we compare RSMZVs to other variants of lifts of SMZVs. Especially, we prove that RSMZVs coincide with Bachmann-Takeyama-Tasaka's $\xi$-values.

description: Ultrasound imaging is one of the most prominent technologies to evaluate the growth, progression, and overall health of a fetus during its gestation. However, the interpretation of the data obtained from such studies is best left to expert physicians and technicians who are trained and well-versed in analyzing such images. To improve the clinical workflow and potentially develop an at-home ultrasound-based fetal monitoring platform, we present a novel fetus phantom ultrasound dataset, FPUS23, which can be used to identify (1) the correct diagnostic planes for estimating fetal biometric values, (2) fetus orientation, (3) their anatomical features, and (4) bounding boxes of the fetus phantom anatomies at 23 weeks gestation. The entire dataset is composed of 15,728 images, which are used to train four different Deep Neural Network models, built upon a ResNet34 backbone, for detecting aforementioned fetus features and use-cases. We have also evaluated the models trained using our FPUS23 dataset, to show that the information learned by these models can be used to substantially increase the accuracy on real-world ultrasound fetus datasets. We make the FPUS23 dataset and the pre-trained models publicly accessible at https://github.com/bharathprabakaran/FPUS23, which will further facilitate future research on fetal ultrasound imaging and analysis.

The Influence of Age and Sex on Measures of Body Size in Captive Chimpanzees (Pan troglodytes) Cared for in African Wildlife Sanctuaries and Zoological Collections

Subjects: Animal developmental and reproductive biology

description: Introduction The typical growth pattern of chimpanzees (Pan troglodytes) has largely been derived from captive research populations, as methodological and ethical challenges limit assessment of their wild counterparts. Despite a lack of empirical evidence, captive research chimpanzees have been suggested to display accelerated growth compared to wild animals. Wild-born sanctuary chimpanzees may provide a more ecologically valid population from which to infer species-typical growth. The aim of this study was to investigate the growth pattern of male and female sanctuary chimpanzees and compare these data to animals in zoological and research facilities. Methods Body mass and crown-rump length were obtained from 150 male and 148 female (aged 1-38 years) African sanctuary chimpanzees. Sex-specific piecewise linear regressions were performed to estimate growth rates and age at maturation. Body mass regressions were compared to those of 454 male and 623 female chimpanzees (aged 1-40 years) acquired from a centralised zoological database. A literature search of peer-reviewed publications was conducted to identify body mass data of research facility populations, which were presented for comparison. Results Male sanctuary chimpanzees attain body mass maturation at an older age compared to females (13.8 vs 12.4 years), but sex differences were not observed in maturation age for crown-rump length or the growth rates for either measure. In comparison to zoological animals, sanctuary chimpanzees had a slower estimated rate of body mass growth and attained maturation at an older age (males:13.8 vs. 12.2 years; females: 12.4 vs. 12.2 years). Sanctuary chimpanzees were also lighter than zoological (males: 53 vs. 61 kg; females: 44 vs. 52 kg) and research animals. Conclusion Together, these results suggest that growth patterns between African sanctuary, zoological and research facility populations of chimpanzees differ. These differences need to be considered when examining life history characteristics in this species. Additionally, these sanctuary data contribute significantly to current understanding of chimpanzee growth.

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

description: We propose a method to determine the power spectrum of \HI column density fluctuations using radio-interferometric observations of 21-cm emission from the ISM of galaxies. We have used this to estimate the power spectra of six nearly face on nearby spiral galaxies. Earlier work has shown that these power spectra are well fitted by power laws with slopes around -1.6 across length-scales $\sim 1 \, {\rm kpc}$ to $\sim 10 \, {\rm kpc}$, the amplitude however was undetermined. In the present work we have determined the amplitude of the \HI column density power spectrum. We find that the \HI column density $N_{\rm HI}$ expressed in units of $10^{20} \, {\rm cm}^{-2}$ has mean square fluctuations in the range $\sim 0.03$ to $\sim 20$. The amplitude of the power spectrum is found to be tightly correlated with the \HI mass fraction of the galaxies. The physical process responsible for these scale-invariant fluctuations is, however, at present not known.

description: We have realized a microstrip based terahertz (THz) near field cantilever that enables quantitative measurements of the impedance of the probe tip at THz frequencies (0.3 THz). A key feature is the on-chip balanced hybrid coupler that serves as an interferometer for passive signal cancellation to increase the readout circuit sensitivity despite extreme impedance mismatch at the tip. We observe distinct changes in the reflection coefficient of the tip when brought into contact with different dielectric (Si, SrTiO3) and metallic samples (Au). By comparing finite element simulations, we determine the sensitivity of our THz probe to be well below 0.25 fF. The cantilever further allows for topography imaging in a conventional atomic force microscope mode. Our THz cantilever removes several critical technology challenges and thus enables a shielded cantilever based THz near field microscope.

description: The rate of maternal mortality has declined significantly across countries in comparison to the burden of morbidity, which continues to remain a significant public health challenge. The World Health Organization (WHO) reports that 15% of all pregnant women will experience potentially fatal complications that would necessitate medical attention. The five most direct obstetric complications (preeclampsia, eclampsia, postpartum hemorrhage, puerperal infection, and abortion) accounted for 27 million morbidity episodes in 2015. Existing studies have established an association between these complications and an increased risk of adverse mental health outcomes in the immediate postpartum period. However, there is no clear understanding as to whether such pregnancy and birth complications increase the risk of adverse mental health outcomes in the longer term. Research on long-term mental outcomes following pregnancy and birth complications is scarce and findings are inconsistent. As little is known about this topic, a systematic review and meta-analysis of population-specific studies attending to the relationship between pregnancy and birth complications and maternal mental health beyond the customary 6 weeks postpartum is warranted. The findings of this review will provide an overview of the current state of knowledge regarding the question of whether having a complicated pregnancy or birth is a separate risk factor for poor mother mental health outcomes beyond the immediate postpartum period.
On the analysis of hybrid models of genetic regulatory networks via a lyapunov approach
Creators: name: Pasquini, Mirko
Publisher: name: Imperial College London
Year: 2020

description: The concept of Genetic Regulatory Network (GRN) is ubiquitous in systems biology, as it describes the transcriptional interactions between genes and proteins, illustrating an intricate set of relations that ultimately guide the genetic expression in a cell. In this dissertation we mainly consider a Piecewise Affine model for the dynamics of Genetic Regulatory Networks, where steep Hill regulatory functions are substituted by step approximations. After an introduction on the model, we define an LMI framework, whose solution describes a generally discontinuous Piecewise Quadratic Lyapunov function for the system. After a discussion on systems solutions when considering isolated Zeno behaviours, the Lyapunov function is proved to be eventually non-increasing along any system trajectory, including any possible sliding motion, and is showed that a Lasalle-like result holds, a result that will allow to characterise convergence properties of the system. After the analysis in the nominal case, acknowledging the fact that biological systems are inherently uncertain, because of environmental changes or imperfect parameters knowledge, polytopic uncertainties are introduced in the model, and the framework is extended to find a Lyapunov function which depends affinely on the uncertain parameters, and that allows to conclude convergence results robust to such uncertainties. In the last Chapter, a more accurate Piecewise Multi-Affine model of the dynamics of Genetic Regulatory Networks is considered, resulting from a Piecewise Linear approximation of Hill functions. It is shown how, using a result on convexity of Multi-Affine functions on hyper-rectangles, a similar LMI framework can be defined, to obtain a Piecewise Quadratic Lyapunov function which is non-increasing along any system trajectory. Throughout the work, many examples show how the LMI Feasibility Problems can be setup, how the theoretical results hold and how these can be used to estimate the convergence sets for the analysed systems.

description: It was recently discovered that a crystalline many-body state can exist in the phase space of a closed dynamical system. A phase space crystal can be an anomalous Chern insulator that supports chiral topological transport without breaking physical time-reversal symmetry [L. Guo et al., Phys. Rev. B 105, 094301 (2022)]. In this work, we further study the effects of an open dissipative environment with thermal noise and identify the existence condition of classical phase space crystals in realistic scenarios. By defining a crystal order parameter, we plot the phase diagram in the parameter space of dissipation rate, interaction, and temperature. Our present work paves the way to realize phase space crystals and explore anomalous chiral transport in experiments.

description: Molekülspektroskopie ist ein wichtiges Werkzeug für die Charakterisierung chemischer Substanzen. Verschiedene Arten von Spektroskopie verwenden die Effekte, die durch Magnetfelder hervorgerufen werden, wie etwa Kernspinresonanz, Elektronenspinresonanz oder Magnetocirculardichroismus. Ihre theoretische Beschreibung erfolgt typischerweise durch quantenchemische Methoden in Kombination mit linearer Störungstheorie, da die Magnetfelder in solchen Experimenten klein sind, verglichen mit den für die chemische Bindung verantwortlichen, elektromagnetischen Kräften. Jenseits der linearen Effekte, die durch einen solchen Ansatz beschrieben werden, liegt eine vielfältige, faszinierende Chemie, die darauf wartet erforscht zu werden. Neue Arten chemischer Bindung, Spinphasenübergänge und Farbveränderungen aromatischer Verbindungen sind nur einige der nicht-linearen Effekte, die durch Magnetfelder hervorgerufen werden. Ihre theoretische Beschreibung erfordert einen Ansatz, in dem ein finites Feld explizit im Hamiltonoperator auftaucht. Solch ein Ansatz kann für eine korrekte Beschreibung von beliebig starken Magnetfeldern verwendet werden. Dadurch wird die Vorhersage spektroskopischer Eigenschaften von Molekülen in der Nähe interstellarer Objekte mit extrem starken Magnetfeldern ermöglicht, wie etwa magnetische Weiße Zwerge oder Neutronensterne. In solchen Fällen kann Molekülspektroskopie verwendet werden, um die Existenz kleiner Moleküle nachzuweisen. Die theoretische Beschreibung eines finiten Feldes erfordert hocheffiziente, rechnergestützte Methoden, deren Entwicklung und Anwendung Thema dieser Arbeit sind. Zunächst werden hierfür die theoretischen Grundlagen für die quantenchemische Beschreibung von Molekülspektroskopie eingeführt. Einige verbreitete Methoden der Quantenchemie werden adaptiert, inklusive der Dichtefunktionaltheorie (DFT), genähertem Coupled-Cluster (CC2), sowie der GW/BSE-Methode. Eine effiziente Implementierung wird entwickelt und getestet. Ausgewählte Anwendungen werden vorgestellt, inklusive Rechnungen an Magnetocirculardichroismusspektren eines organometallischen Komplexes, die Vorhersage der Farbveränderung von Tetracen im Magnetfeld mithilfe der UV/Vis-Spektroskopie, sowie die Untersuchung von Schwingungsrotationsspektren zweiatomiger Moleküle in starken Magnetfeldern.

description: Let $T_R$ be a $1$-tilting module with tilting torsion pair $(\operatorname{Gen} T, \mathcal{F})$ in $\mathrm{Mod}\textrm{-}R.$ The following conditions are proved to be equivalent: (1) $T$ is pure projective; (2) $\operatorname{Gen} T$ is a definable subcategory of $\mathrm{Mod}\textrm{-}R$ with enough pure projectives; (3) both classes $\operatorname{Gen} T$ and $\mathcal{F}$ are finitely axiomatizable; and (4) the heart of the corresponding HRS $t$-structure (in the derived category $\mathcal{D}^b (\mathrm{Mod}\textrm{-}R)$) is Grothendieck. This article explores in this context the question raised by Saor\'{i}n if the Grothendieck condition on the heart of an HRS $t$-structure implies that it is equivalent to a module category. This amounts to asking if $T$ is tilting equivalent to a finitely presented module. This is resolved in the positive for a Krull-Schmidt ring, and for a commutative ring, a positive answer follows from a proof that every pure projective $1$-tilting module is projective. However, a general criterion is found that yields a negative answer to Saor\'{i}n's Question and this criterion is satisfied by the universal enveloping algebra of a semisimple Lie algebra, a left and right noetherian domain.

description: At the Large Hadron Collider (LHC), the trigger systems for the detectors must be able to process a very large amount of data in a very limited amount of time, so that the nominal collision rate of 40 MHz can be reduced to a data rate that can be stored and processed in a reasonable amount of time. This need for high performance places very stringent requirements on the complexity of the algorithms that can be used for identifying events of interest in the trigger system, which potentially limits the ability to trigger on signatures of various new physics models. In this paper, we present an alternative tracking algorithm, based on the Hough transform, which avoids many of the problems associated with the standard combinatorial track finding currently used. The Hough transform is also well-adapted for Graphics Processing Unit (GPU)-based computing, and such GPU-based systems could be easily integrated into the existing High-Level Trigger (HLT). This algorithm offers the ability to trigger on topological signatures of new physics currently not practical to reconstruct, such as events with jets or black holes significantly displaced from the primary vertex. This paper presents, for the first time, an implementation and preliminary performance results using NVIDIA Tesla C2075 and K20c GPUs.

description: A problem of constructing the trajectory of a spacecraft flight to Venus within the framework of a mission including landing of a lander in a given region of the planet's surface is being considered. A new celestial mechanics related method based on the use of gravity assist maneuver near Venus is proposed to transfer the spacecraft to a heliocentric orbit resonant with the orbit of Venus, so that, at the next approach the planet, the given region of the surface becomes attainable for landing. It is shown that the best resonant orbit in terms of the cost of the characteristic velocity is an orbit with a 1:1 ratio of the period to the orbital period of Venus. A procedure for choosing one of possible resonant orbits depending on coordinates of the desired landing point on the surface and the launch date of the mission is described. An example of calculating the flight trajectory that ensures landing in the Vellamo-South region of the Venus surface at launch from the Earth in 2031 is considered.

REMARKS: name that Rondani (1868c: 242) proposed in synonymy and was not made available by use as a valid species before 1961. Zetterstedt (1847: 2336) described a male and a female from Italy but did not name them. Rondani (1868c: 242) proposed the name Sapromyza zetterstedtii for these latter specimens and considered it as a junior synonym of Sapromyza subvittata Loew, 1847. Neither Becker (1905) nor Papp (1984a) considered Sapromyza zetterstedtii as a valid species and, as far as we know, neither did anyone else. For this latter reason, the name Sapromyza zetterstedtii is unavailable (I.C.Z.N. 1999: Article 11.6.1). O’Hara et al. (2011: 215) considered the name as unavailable.

description: The performance of two implementations of digital real-time interpolating constant fraction discriminator algorithms with respect to fast-timing lifetime measurements are investigated. The implementations integrated in two different digitizers were evaluated in terms of the effects of tuning parameters of the digital CFDs and the influence of different input amplitudes on the time resolution and time walk characteristics. Reference is made to the existing analog standard of fast-timing techniques. The study shows, that the timing performance of both modules is comparable to established fast-timing setups using analog constant fraction discriminators, but with the added benefit of digital processing. Both digitizer modules were found to be highly effective and user-friendly instruments for modern fast-timing requirements.

description: We investigate the dependence of residual rotation measure (RRM) on intervening absorption systems at cosmic distances by using a large sample of 539 SDSS quasars in conjunction with the available rotation measure catalog at around 21cm wavelength. We found an excess extragalactic contribution in standard deviation of observed RRM of about 8.11+/-4.83 Rad/m^2 in our sample with intervening MgII absorber as compare to the sample without MgII absorber. Our results suggest that intervening absorbers could contribute to the enhancement of RRM at around 21cm wavelength, as was found earlier for RM measurements at around 6cm wavelength.

description: Weak-signal detection and single-particle selection from low-contrast micrographs of frozen hydrated biomolecules by cryo-electron microscopy (cryo-EM) presents a practical challenge. Cryo-EM image contrast degrades as the size of biomolecules of structural interest decreases. When the image contrast falls into a range where the location or presence of single particles becomes ambiguous, a need arises for objective computational approaches to detect weak signal and to select and verify particles from these low-contrast micrographs. Here we propose an objective validation scheme for low-contrast particle selection using a combination of two different target functions. In an implementation of this dual-target function (DTF) validation, a first target function of fast local correlation was used to select particles through template matching, followed by signal validation through a second target function of maximum likelihood. By a systematic study of simulated data, we found that such an implementation of DTF validation is capable of selecting and verifying particles from cryo-EM micrographs with a signal-to-noise ratio as low as 0.002. Importantly, we demonstrated that DTF validation can robustly evade over-fitting or reference bias from the particle-picking template, allowing true signal to emerge from amidst heavy noise in an objective fashion. The DTF approach allows efficient assembly of a large number of single-particle cryo-EM images of smaller biomolecules or specimens containing contrast-degrading agents like detergents in a semi-automatic manner.

Studies in statistical physics of complex systems
Creators: name: Palmieri, Lorenzo
Publisher: name: Imperial College London
Year: 2020

description: This thesis is divided into five chapters and is the result of the research I carried out during my time as a PhD student at Imperial College London. In chapter 1, I introduce the results of my research and place my work in the context of the existing literature. In chapter 2, I present a novel method to analyse the critical behaviour of complex systems and discuss its application to three case studies: two from equilibrium statistical mechanics (the Ising Model and the XY Model) and one from self-organised criticality (the Forest Fire Model). In chapter 3, I focus my attention on the Forest Fire Model and discuss its relevance for the study of real systems, like the brain and rain precipitation. I also analyse the distribution of the largest cluster and show that it displays a behaviour that is consistent with the observations done in chapter 2. In chapter 4, I introduce an agent-based model of financial networks which is inspired by the Tangled Nature Model of evolutionary ecology. This model can qualitatively reproduce the evolution of the number of banks in the U.S. and the behaviour of the firm size distribution observed in different countries. I also discuss the effectiveness of Quantitative Easing in dealing with financial crashes and present information-theoretic measures that could be used to track, and possibly prevent, the development of the instabilities leading to a crash. In chapter 5, I summarise my results and discuss some possible research that could be fostered by this thesis.

Special Groups, Versality and the Grothendieck-Serre Conjecture

description: Let $k$ be a base field and $G$ be an algebraic group over $k$. J.-P. Serre defined $G$ to be special if every $G$-torsor $T \to X$ is locally trivial in the Zariski topology for every reduced algebraic variety $X$ defined over $k$. In recent papers an a priori weaker condition is used: $G$ is called special if every $G$-torsor $T \to \operatorname{Spec}(K)$ is split for every field~$K$ containing $k$. We show that these two definitions are equivalent. We also generalize this fact and propose a strengthened version of the Grothendieck-Serre conjecture based on the notion of essential dimension.

Modelling delamination in fibre-reinforced composites via stress gradient elasticity
Creators: name: Gaite, Oliver Anthony Lawrence
Publisher: name: Imperial College London

description: Continuous fibre-reinforced polymer (CFRP) composites are susceptible to damage by delamination. Simulation of delamination initiation and propagation are valuable mitigation strategies in designing and lifing CFRP assets. Linear elastic fracture mechanics (LEFM) predicts infinite stresses at the tips of sharp, discrete delaminations. In order to determine whether a delamination front will advance, finite element method (FEM) approaches utilise non-linear decohesion elements that consume energy equivalent to the material fracture toughness. Nonlocal field theory predicts a non-zero finite stress at the delamination front, with a maximum stress occuring some distance ahead of the crack. Nonlocal stress fields therefore offer the prospect of a linear maximum stress fracture criterion. Since nonlocal elasticity is predicated on the concept of non-finite range forces, the theory predicts that the stresses at the crack tip will be redistributed over some proximate region that must include part of the crack wake. Nonlocal FEM implementations require that these crack wake tractions are artifically imposed (as they do not result from FEM approximations that otherwise rely on LEFM). If the necessary redistribution of stress concentrations ahead of the crack is explicitly imposed on the free edges of the crack in its wake, continuous stress and strain fields are recovered. Moreover the work performed by the imposed crack wake tractions is equivalent to the interlaminar fracture toughness of the material such that stress and energetic fracture criteria are unified. To the best of the author’s knowledge use of the imposed crack wake tractions is novel in a finite element context. The material constitutive equations are written in a nonlocal form and incorporated into a finite element method solver by a procedure that produces a global stiffness matrix containing banded terms accounting for the cross-bracing inherent in nonlocal fields. The solution to the crack wake traction distribution is imposed by modelling the tractions as discrete springs and augmenting the global stiffness matrix with these stiffness terms. Nonlocal mode I and mode II delamination propagation has been explored and compared to benchmark analyses obtain from local elasticity using the virtual crack closure technique (VCCT). The behaviour of the present implementation of nonlocal FEM is observed to differ with respect to each of these crack opening modes. In the case of the mode I delamination, the stress response is underpredicted by 8.6%. In the case of the mode II delamination, the stress response is overestimated by 2.4%. In a static mixed-mode analysis, the present implementation of nonlocal elasticity does not produce behaviour consistent with the mixed-mode fracture toughness.

description: Mutations in the SNCA gene cause autosomal dominant Parkinson's disease (PD), with loss of dopaminergic neurons in the substantia nigra, and aggregation of α-synuclein. The sequence of molecular events that proceed from an SNCA mutation during development, to end-stage pathology is unknown. Utilising human-induced pluripotent stem cells (hiPSCs), we resolved the temporal sequence of SNCA-induced pathophysiological events in order to discover early, and likely causative, events. Our small molecule-based protocol generates highly enriched midbrain dopaminergic (mDA) neurons: molecular identity was confirmed using single-cell RNA sequencing and proteomics, and functional identity was established through dopamine synthesis, and measures of electrophysiological activity. At the earliest stage of differentiation, prior to maturation to mDA neurons, we demonstrate the formation of small β-sheet-rich oligomeric aggregates, in SNCA-mutant cultures. Aggregation persists and progresses, ultimately resulting in the accumulation of phosphorylated α-synuclein aggregates. Impaired intracellular calcium signalling, increased basal calcium, and impairments in mitochondrial calcium handling occurred early at day 34-41 post differentiation. Once midbrain identity fully developed, at day 48-62 post differentiation, SNCA-mutant neurons exhibited mitochondrial dysfunction, oxidative stress, lysosomal swelling and increased autophagy. Ultimately these multiple cellular stresses lead to abnormal excitability, altered neuronal activity, and cell death. Our differentiation paradigm generates an efficient model for studying disease mechanisms in PD and highlights that protein misfolding to generate intraneuronal oligomers is one of the earliest critical events driving disease in human neurons, rather than a late-stage hallmark of the disease.
