description: Absorption and luminescence excitation spectra of Xe/CF4 mixtures were studied in the vacuum UV region at high resolution using tunable synchrotron radiation. Pressure-broadened resonance bands and bands associated with dipole-forbidden states of the Xe atom due to collision-induced breakdown of the optical selection rules are reported. The spectra display in addition numerous satellite bands corresponding to transitions to vibrationally excited states of a Xe-CF4 collisional complex. These satellites are located at energies of Xe atom transition increased by one quantum energy in the IR active v 3 vibrational mode of CF4 (v 3 = 1281 cm−1). Satellites of both resonance and dipole-forbidden transitions were observed. Satellites of low lying resonance states are spectrally broad bands closely resembling in shape their parent pressure-broadened resonance bands. In contrast, satellites of dipole-forbidden states and of high lying resonance states are spectrally narrow bands (FWHM ∼10 cm−1). The satellites of dipole-forbidden states are orders of magnitude stronger than transitions to their parent states due to collision-induced breakdown of the optical selection rules. These satellites are attributed to a coupling of dipole-forbidden and resonance states induced by the electric field of the transient CF4 (v 3 = 0 ↔ v 3 = 1) dipole. Similar satellites are present in spectra of Xe/C2F6 mixtures where these bands are induced by the IR active v 10 mode of C2F6. Transitions to vibrationally excited states of Xe-CF4(C2F6) collision pairs were also observed in two- photon LIF spectra.
Authenticity and Death in Being and Time

description: My dissertation offers a critique of the concept of authenticity that Martin Heidegger develops in Being and Time. The concept of authenticity has been critiqued for many reasons--mainly for political, moral, and ideological reasons. My dissertation develops, on the other hand, a conceptual critique: I argue that the concept of authenticity is a paradoxical concept. I argue, more precisely, that it is paradoxical, as the concept of authenticity proposes, for a person to confront, transparently and determinedly, his or her own death, while, at the same time, being able to be an individual--understanding him or herself as an individual, and making autonomous choices. In offering this critique, I provide interpretations of some of the basic concepts in Being and Time that break from conventional interpretations or are new. For example, I interpret the concept of inauthenticity from the perspective of the psychoanalytic idea of mania. Ultimately, however, I provide philosophical, or conceptual reasons to resist a concept with clearly problematic moral and political implications.

Authorial Cameos in Post-Romantic Russian Literature

Publisher: name: Columbia University
Year: 2012
Subjects: Slavs

description: This dissertation examines representations of authorship in Russian literature from a number of perspectives, including the specific Russian cultural context as well as the broader discourses of romanticism, autobiography, and narrative theory. My main focus is a narrative device I call "the figured author," that is, a background character in whom the reader may recognize the author of the work.  I analyze the significance of the figured author in the works of several Russian nineteenth- and twentieth- century authors in an attempt to understand the influence of culture and literary tradition on the way Russian writers view and portray authorship and the self.  The four chapters of my dissertation analyze the significance of the figured author in the following works: 1) Pushkin's Eugene Onegin and Gogol's Dead Souls; 2) Chekhov's "Ariadna"; 3) Bulgakov's "Morphine"; 4) Nabokov's The Gift.  In the Conclusion, I offer brief readings of Kharms's "The Old Woman" and "A Fairy Tale" and Zoshchenko's Youth Restored. One feature in particular stands out when examining these works in the Russian context: from Pushkin to Nabokov and Kharms, the "I" of the figured author gradually recedes further into the margins of narrative, until this figure becomes a third-person presence, a "he." Such a deflation of the authorial "I" can be seen as symptomatic of the heightened self-consciousness of Russian culture, and its literature in particular.  By examining figured authors across these works, I explore authorship in Russia as a self-questioning, and potentially self-erasing, practice.

description: Este estudio analiza un caso de interseccionalidad de identificaciones de clase, étnicas y raciales, en base al momento de origen del peronismo. El 17 de octubre de 1945 los trabajadores de los suburbios ingresaron a la ciudad de Buenos Aires y marcharon a Plaza de Mayo a reclamar la libertad del coronel Perón. Con aquel episodio estalló el sistema de clasificaciones sociales de la Argentina. Surgieron una serie de nuevas categorías (descamisado, cabecita negra) así como se resignificaron otras (criollo, argentino). El estudio aporta a los debates de la teoría cultural a partir este caso histórico. Contribuye a comprender desde otra perspectiva los orígenes del peronismo y del antiperonismo, y permite analizar las complejidades de los imaginarios nacionales argentinos. Por ello postula que la sociedad argentina está constituida sobre las jerarquizaciones de un racismo que no se estudia, salvo en las nuevas generaciones.

description: The R package emdi offers a methodological and computational framework for the estimation of regionally disaggregated indicators using small area estimation methods and provides tools for assessing, processing and presenting the results. A range of indicators that includes the mean of the target variable, the quantiles of its distribution and complex, non-linear indicators or customized indicators can be estimated simultaneously using direct estimation and the empirical best predictor (EBP) approach (Molina and Rao 2010). In the application presented in this paper package emdi is used for estimating inequality indicators and the median of the income distributions for small areas in Austria. Because the EBP approach relies on the normality of the mixed model error terms, the user is further assisted by an automatic selection of data-driven transformation parameters. Estimating the uncertainty of small area estimates (using a mean squared error - MSE measure) is achieved by using both parametric bootstrap and semi-parametric wild bootstrap. The additional uncertainty due to the estimation of the transformation parameter is also captured in MSE estimation. The semi-parametric wild bootstrap further protects the user against departures from the assumptions of the mixed model in particular, those of the unit-level error term. The bootstrap schemes are facilitated by computationally effcient code that uses parallel computing. The package supports the users beyond the production of small area estimates. Firstly, tools are provided for exploring the structure of the data and for diagnostic analysis of the model assumptions. Secondly, tools that allow the spatial mapping of the estimates enable the user to create high quality visualizations. Thirdly, results and model summaries can be exported to Excel™ spreadsheets for further reporting purposes.

description: Artificial intelligence powered by deep neural networks has seen tremendous improvements in the last decade, achieving superhuman performance on a diverse range of tasks. Many worry that it can one day develop the ability to recursively self-improve itself, leading to an intelligence explosion known as the Singularity. Autogenerative networks, or neural networks generating neural networks, is one major plausible pathway towards realizing this possibility. The object of this thesis is to study various challenges and applications of small-scale autogenerative networks in domains such as artificial life, reinforcement learning, neural network initialization and optimization, gradient-based meta-learning, and logical networks. Chapters 2 and 3 describe novel mechanisms for generating neural network weights and embeddings. Chapters 4 and 5 identify problems and propose solutions to fix optimization difficulties in differentiable mechanisms of neural network generation known as Hypernetworks. Chapters 6 and 7 study implicit models of network generation like backpropagating through gradient descent itself and integrating discrete solvers into continuous functions. Together, the chapters in this thesiscontribute novel proposals for non-differentiable neural network generation mechanisms, significant improvements to existing differentiable network generation mechanisms, and an assimilation of different learning paradigms in autogenerative networks.

description: Non-compact three-dimensional QED is studied by computer simulations to understand its chiral symmetry breaking features for N_f>=2, on lattice volumes up to 50^3 and bare masses as low as ma=0.0000625. We compute the chiral condensate, scalar and pseudoscalar susceptibilities, and the masses of scalar and pseudoscalar mesons. Finite volume effects and discretisation artifacts are carefully monitored. Our results reveal no decisive signal for chiral symmetry breaking for any N_f>=2. For N_f=2 the dimensionless condensate can be bounded by beta^2 <= 5x10^-5. We also present an exploratory study of the fractionally-charged Polyakov line.

description: The normal ordering formulae for powers of the boson number operator $\hat{n}$ are extended to deformed bosons. It is found that for the `M-type' deformed bosons, which satisfy $a a^{\dagger} - q a^{\dagger} a = 1$, the extension involves a set of deformed Stirling numbers which replace the Stirling numbers occurring in the conventional case. On the other hand, the deformed Stirling numbers which have to be introduced in the case of the `P-type' deformed bosons, which satisfy $a a^{\dagger} - q a^{\dagger} a = q^{-\hat{n}}$, are found to depend on the operator $\hat{n}$. This distinction between the two types of deformed bosons is in harmony with earlier observations made in the context of a study of the extended Campbell-Baker-Hausdorff formula.

description: In a world going towards automation, I ask whether salespeople making pricing decisions in a high human interaction environment such as business to business (B2B) retail, could be automated, and under what conditions it would be most beneficial. I propose a hybrid approach to automation that combines the expert salesperson and an artificial intelligence model of the salesperson in making pricing decisions in B2B. The hybrid approach preserves individual and organizational knowledge both by learning the expert's decision making behavior and by keeping the expert in the decision making process for decisions that require human judgment. Using sales transactions data from a B2B aluminum retailer, I create an automated version of each salesperson, that learns the salesperson's pricing policy based on her past pricing decisions. In a field experiment, I provide salespeople in the B2B retailer with their own model's price recommendations through their CRM system in real-time, and allow them to adjust their original pricing accordingly. I find that despite the loss of non-codeable information that is available to the salesperson but not to the model, providing the model's price increases profits for treated quotes by as much as 10% relative to a control condition, which translates to approximately $1.3 million in yearly profits. Using a counterfactual analysis, I also find that a hybrid pricing approach, that follows the model's pricing most of time, but defers to the salesperson's pricing when the model is missing important information is more profitable than pure automation or pure reliance on the salesperson's pricing. I find that in most cases the model's scalability and consistency lead to better pricing decisions that translate to higher profits, but when pricing uncommon products or pricing for unfamiliar clients it is best to use human judgment. I investigate different ways, including machine learning methods, to model the salesperson's behavior and to combine salespeople's expertise as reflected by their automated representations, and discuss implications for  automation of tasks that involve soft skills.

description: Spin qubits in silicon quantum dots are one of the most promising building blocks for large scale quantum computers thanks to their high qubit density and compatibility with the existing semiconductor technologies. High fidelity single-qubit gates exceeding the threshold of error correction codes like the surface code have been demonstrated, while two-qubit gates have reached 98\% fidelity and are improving rapidly. However, there are other types of error --- such as charge leakage and propagation --- that may occur in quantum dot arrays and which cannot be corrected by quantum error correction codes, making them potentially damaging even when their probability is small. We propose a surface code architecture for silicon quantum dot spin qubits that is robust against leakage errors by incorporating multi-electron mediator dots. Charge leakage in the qubit dots is transferred to the mediator dots via charge relaxation processes and then removed using charge reservoirs attached to the mediators. A stabiliser-check cycle, optimised for our hardware, then removes the correlations between the residual physical errors. Through simulations we obtain the surface code threshold for the charge leakage errors and show that in our architecture the damage due to charge leakage errors is reduced to a similar level to that of the usual depolarising gate noise. Spin leakage errors in our architecture are constrained to only ancilla qubits and can be removed during quantum error correction via reinitialisations of ancillae, which ensure the robustness of our architecture against spin leakage as well. Our use of an elongated mediator dots creates spaces throughout the quantum dot array for charge reservoirs, measuring devices and control gates, providing the scalability in the design.

description: The strong gravitational field near massive blackhole is an interesting regime to test General Relativity(GR) and modified gravity theories. The knowledge of spacetime metric around a blackhole is a primary step for such tests. Solving field equations for rotating blackhole is extremely challenging task for the most modified gravity theories. Though the derivation of Kerr metric of GR is also demanding job, the magical Newmann-Janis algorithm does it without actually solving Einstein equation for rotating blackhole. Due to this notable success of Newmann-Janis algorithm in the case of Kerr metric, it has been being used to obtain rotating blackhole solution in modified gravity theories. In this work, we derive the spacetime metric for the external region of a rotating blackhole in a nonlocal gravity theory using Newmann-Janis algorithm. We also derive metric for a slowly rotating blackhole by perturbatively solving field equations of the theory. We discuss the applicability of Newmann-Janis algorithm to nonlocal gravity by comparing slow rotation limit of the metric obtained through Newmann-Janis algorithm with slowly rotating solution of the field equation.

description: In the present study, the reactions involving caffeine (CA) and gold(III) were investigated. The synthesized complex was characterized by using mass, UV–visible, FTIR, 1H and 13C NMR, and TG-DTA analyses. From these analyses, it is predicted that the complex has the formula [Au(CA)2(Cl)2]Cl. In addition, antimicrobial, cytotoxicity, and antioxidant activities of the obtained complex were investigated. Investigation of antimicrobial properties demonstrated that the complex has important antibacterial and antifungal activities. The cytotoxic activity of the complex showed potent cytotoxicity against growth of human prostate (Du145), cervix (HeLa), colon (HT29), and breast (MCF7) cancer cells. Additionally, the complex showed significant antioxidant activity.

description: We present measurements of the resonant microwave excitation of the Rydberg energy levels of surface state electrons on superfluid helium. The temperature dependent linewidth agrees well with theoretical predictions and is very small below 300 mK. Absorption saturation and power broadening were observed as the fraction of electrons in the first excited state was increased to 0.49, close to the thermal excitation limit of 0.5. The Rabi frequency was determined as a function of microwave power. The high values of the ratio of the Rabi frequency to linewidth confirm this system as an excellent candidate for creating qubits.

Autophagy-linked FYVE protein mediates the turnover of mutant huntingtin and modifies pathogenesis in mouse models of Huntington’s disease

description: A defining characteristic of neurodegenerative disease is the accumulation of mutant or misfolded proteins within neurons. Selective macroautophagy of aggregates, or aggrephagy, is a lysosome-mediated protein degradation pathway implicated in the turnover of disease-relevant accumulated proteins, but its specific function in vivo in the mammalian nervous system is poorly understood. The large PI3P-binding protein Alfy (Autophagy-linked FYVE protein) is an adaptor required for selective macroautophagy of aggregated proteins in cellular model systems. We sought to address Alfy-mediated aggrephagy in the mammalian brain in mouse models of Huntington’s disease (HD).
      HD is a neurodegenerative disorder caused by autosomal dominant inheritance of an expanded CAG repeat within the IT15, or huntingtin (htt) gene. The mutation causes an expansion of a polyglutamine (polyQ) tract in the protein Huntingtin (Htt), which results in psychiatric, cognitive, and motor symptomology. A pathological hallmark of HD is the accumulation of intracellular deposits of mutant Htt and ubiquitin. The exact relevance of these deposits remains unclear, but their elimination, hypothesized to occur via macroautophagy, correlates with behavioral improvements in mouse models of HD. The selective mechanisms of this phenomenon are largely unexplored in vivo.
      We have created two mouse models to address the role of Alfy-mediated selective macroautophagy in mammalian HD brain. First, we created tamoxifen-inducible Alfy knockout mice (Alfy iKO) and crossed them with a redesigned inducible HD mouse (HD103Q) that uses a tetracycline-regulated system to control reversible expression of mutant exon-1 Htt. Western blot, in situ, and PCR analysis confirm that Alfy can be eliminated from brain in adult Alfy iKO mice. A timecourse of Htt aggregation and clearance reveals that HD103Q mice accumulate huntingtin deposits, which clear in a linear manner upon transgene suppression over the course of four months. The loss of Alfy significantly impedes the removal of these deposits. Second, an Alfy knockout mouse was created using gene-trap technology, and mice hemizygous for Alfy knockout were crossed with BACHD mice expressing full-length human mutant Htt. We find that 50% Alfy depletion in the BACHD leads to increased insoluble Htt aggregate deposition along with accelerated decline in motor behavioral performance. Furthermore, inducible knockout of Alfy alone has a severe and age-dependent motor behavioral phenotype. This work reveals an in vivo role for Alfy in turnover of mutant Htt deposits, suggests that the accumulation of detergent-insoluble mutant Htt species contributes to behavioral pathogenesis, and supports an important function for Alfy at the intersection of HD and aging.

description: This dissertation examines the avant-garde as one of the last significant cultural manifestations in Latin America that attempted to offer an alternative to capitalism in the twentieth century. My study redefines the avant-garde as a global critique of modernity whose emergence can only be explained from a geopolitical perspective. During this time, the world order dictated that metropolitan areas like Western Europe be engaged in a mutual economic dependence with peripheral regions such as Latin America. Consequently, a revolutionary socialist impulse originated from within secondary economic areas in the world like Russia and Latin America. Movements such as Dada and Cubism conveyed the necessity for art to break from the autonomous status attributed to it by the bourgeoisie; but ultimately, these aesthetic projects did not address an essential component of the changing social picture, namely the articulation of collective fantasies directed at the emerging masses.  The avant-garde was able to articulate these dreamworlds only after art intersected with socialism. With this convergence art claimed a different kind of autonomy, one not based on innocuous insularity but on a socially conscious critical capacity. The revolutionary discourse that resulted from the combination of political and artistic realms aimed at addressing the masses as an integral part of a new modern society. The chapters include muralism (Diego Rivera), periodicals (Amauta), and poetry (Vallejo). Building upon local and global geopolitical perspectives, these works constructed socialist dreamworlds, expressions of utopian desires to transform the world, against the backdrop of art's tendency toward new modes of production and aesthetic sensibilities in the early twentieth century. Sifting through the ruins of these cultural artifacts, I discuss topics such as the figure of the intellectual and the history of radical ideas in Latin America; Marxism; public art and state sponsorship; iconography of revolution and spectrality; and the autonomy of art at the intersection of politics and aesthetics.

description: Hyperspectral unmixing aims at identifying a set of elementary spectra and the corresponding mixture coefficients for each pixel of an image. As the elementary spectra correspond to the reflectance spectra of real materials, they are often very correlated yielding an ill-conditioned problem. To enrich the model and to reduce ambiguity due to the high correlation, it is common to introduce spatial information to complement the spectral information. The most common way to introduce spatial information is to rely on a spatial regularization of the abundance maps. In this paper, instead of considering a simple but limited regularization process, spatial information is directly incorporated through the newly proposed context of spatial unmixing. Contextual features are extracted for each pixel and this additional set of observations is decomposed according to a linear model. Finally the spatial and spectral observations are unmixed jointly through a cofactorization model. In particular, this model introduces a coupling term used to identify clusters of shared spatial and spectral signatures. An evaluation of the proposed method is conducted on synthetic and real data and shows that results are accurate and also very meaningful since they describe both spatially and spectrally the various areas of the scene.

description: How much work can be extracted from a heat bath using a thermal machine? The study of this question has a very long history in statistical physics in the weak-coupling limit, when applied to macroscopic systems. However, the assumption that thermal heat baths remain uncorrelated with associated physical systems is less reasonable on the nano-scale and in the quantum setting. In this work, we establish a framework of work extraction in the presence of quantum correlations. We show in a mathematically rigorous and quantitative fashion that quantum correlations and entanglement emerge as limitations to work extraction compared to what would be allowed by the second law of thermodynamics. At the heart of the approach are operations that capture the naturally non-equilibrium dynamics encountered when putting physical systems into contact with each other. We discuss various limits that relate to known results and put our work into the context of approaches to finite-time quantum thermodynamics.

description: We study the behavior of two particles moving in a bistable potential, colliding inelastically with each other and driven by a stochastic heat bath. The system has the tendency to clusterize, placing the particles in the same well at low drivings, and to fill all of the available space at high temperatures. We show that the hopping over the potential barrier occurs following the Arrhenius rate, where the heat bath temperature is replaced by the granular temperature. Moreover, within the clusterized ``phase'' one encounters two different scenarios: for moderate inelasticity, the jumps from one well to the other involve one particle at a time, whereas for strong inelasticity the two particles hop simultaneously.

description: Amyotrophic Lateral Sclerosis (ALS) is a debilitating and fatal neurodegenerative disease affecting upper and lower motor neurons.  Though studied for over two decades since the first ALS-associated genetic mutation was discovered, researchers have yet to uncover the pathological processes that lead to progressive degeneration of motor neurons in ALS, or to develop effective treatments. One prominent hypothesis proposes that excitotoxicity caused by increased motor neuron firing plays a role in ALS pathogenesis.  While prior studies reported increased action potential firing in early postnatal ALS-model motor neurons in vivo, it remains unknown whether the increased activity stems from increased intrinsic excitability of ALS motor neurons or from increased excitatory drive, and whether these changes are transient or persist into adulthood, when ALS symptoms emerge.
      	In this thesis, I circumvented the difficulties in standard measurement of electrophysiological properties of adult spinal motor neurons in vivo by relying on the visualization of the axon initial segment, a subcellular structure known to undergo compensatory structural changes in response to perturbations in excitatory input.  I discovered that cultured motor neurons derived from stem cells of the SOD1G93A mouse model of ALS display shortened axon initial segments and hypoexcitable electrophysiological properties.  The shortening of the axon initial segment is compensatory, as ALS motor neurons receive increased numbers of excitatory inputs and manifest increased spontaneous activity.  Remarkably, similar shortening of the axon initial segment was detected in early presymptomatic spinal motor neurons in vivo.  The shortened axon initial segment persists into the symptomatic stages and is particularly pronounced in motor neurons containing p62 immunoreactive aggregates and neurons exhibiting swollen mitochondria, two signs of stress and neurodegeneration in the disease.  Based on these observations I propose that early in the presymptomatic stages of the disease, spinal motor neurons recruit excessive excitatory inputs, resulting in their increased activity that is in part compensated by shortening of the axon initial segment.  This state persists and becomes even more pronounced in motor neurons exhibiting biochemical changes preceding neurodegeneration.
      	While these observations support the potential role for excitotoxic stress in spinal ALS motor neurons, I paradoxically observed the opposite phenotype in ALS-vulnerable cranial motor neurons in the brainstem of the SOD1G93A animals, raising the possibility that the cellular stress that drives the neurodegeneration in ALS is motor neuron subtype specific.

description: We consider a parabolic-like systems of differential equations involving geometrical quantities to examine uniformization theorems for two- and three-dimensional closed orientable manifolds. We find that in the two-dimensional case there is a simple gauge theoretic flow for a connection built from a Riemannian structure, and that the convergence of the flow to the fixed points is consistent with the Poincare Uniformization Theorem. We construct a similar system for the three-dimensional case. Here the connection is built from a Riemannian geometry, an SO(3) connection and two other 1-form fields which take their values in the SO(3) algebra. The flat connections include the eight homogeneous geometries relevant to the three-dimensional uniformization theorem conjectured by W. Thurston. The fixed points of the flow include, besides the flat connections (and their local deformations), non-flat solutions of the Yang-Mills equations. These latter "instanton" configurations may be relevant to the fact that generic 3-manifolds do not admit one of the homogeneous geometries, but may be decomposed into "simple 3-manifolds" which do.

description: The Andes, along with the Amazon and Atlantic forests, harbor the richest avifauna in the world with roughly one third of all the world's species of birds. Many biogeographical studies have sought to explain the origin and diversification of Andean taxa. However, because of the Andes' extensive latitudinal span and complexity, there is no one single cause of origin or of diversification that can explain the diversity found in them. Along the Andes, multiple biogeographic patterns of disjunction between highland and lowland sister-groups have been linked to Andean uplift. For example, Ribas et al. (2007) provided evidence that the spatio-temporal diversification in the monophyletic parrot genus Pionus is causally linked to Andean tectonic and palaeoclimate change through vicariance. Thus, if the Andes uplift is responsible for some of the patterns of montane-lowland disjunctions, it may be one of the mechanisms underlying the taxonomic assembly of the Andean montane avifauna. In this dissertation I explored whether the origin and diversification of three groups of Andean birds--the exclusively Andean parrot genera Hapalopsittaca, the subclade of mangoes containing Doryfera, Schistes, and Colibri, and the ovenbirds of the tribe Thripophagini--can be linked to Earth history. The results show that the origin of these Andean taxa can be explained through vicariance from their lowland sister-groups, mediated by the uplift of the Andes. Thus, this thesis proposes that geological events are directly responsible for originating diversity throughout montane environments. Once in the Andes, the diversification of these montane taxa can be explained by events such as the tectonic evolution of the Andes--which created canyons and valleys that may have caused the vicariance of continuous populations--as well as by the climatic oscillation of the Pleistocene, which caused altitudinal shifts, expansion, and contraction of the montane vegetation belts during the climatic oscillations of the Pleistocene. In summary a significant part of the temporal patterns of origins and diversification of the three groups of birds included in this study can be linked to Earth history, both in terms of the tectonic history of the Andes and of the climatic events of the Pleistocene.

 Megapus longipes Halbert, 1944

 Syn. to A. acutirostris Motaş & Angelier, 1927: syn. nov.
 Type series: Holotype ♀, MNHD Megapus longipes n. sp. ♀ ovig. Type. R. Flesk, Killarney (E Bullock) April 42. State of conservation: idiosoma in toto, flattened, Cx-1 + 2 damaged, gnathosoma in toto laterally, all legs complete, mounting fluid in good condition.
 Discussion: Halbert considered A. longipes to be similar to A. acutirostris. Indeed, both species agree, and differ from all species of the subgenus known at that time, in the narrow setal interspace. A revision of several specimens from a wide geographical area demonstrated a certain variability of the position of these setae (normally side by side, but occasionally on one of the legs shifted against another); their position one behind the other in the holotype of A. longipes is therefore not taxonomically significant. A. elongatus is probably a juvenile, and A. longipes a more advanced adult of the same species. After the first description, A. longipes has been recorded once more from an Irish river (Conroy, 1978), but without discussion of morphological details.
