description: The presence of gauge symmetry in 1+1D is known to be redundant, since it does not imply the existence of dynamical gauge bosons. As a consequence, in the continuum, the Abelian-Higgs model, the theory of bosonic matter interacting with photons, just possesses a single phase, as the higher dimensional Higgs and Coulomb phases are connected via non-perturbative effects. However, recent research published in [Phys. Rev. Lett. 128, 090601 (2022)] has revealed an unexpected phase transition when the system is discretized on the lattice. This transition is described by a conformal field theory with a central charge of $c=3/2$. In this paper, we aim to characterize the two components of this $c=3/2$ theory -- namely the free Majorana fermionic and bosonic parts -- through equilibrium and out-of-equilibrium spectral analyses.

description: Background: Coastal dunes are dynamic ecosystems, with vegetation seen as a key element in the response to a continuously changing environment.Aims: We explored co-occurrence patterns of plant species within dune ecosystems along a regional climatic and a local sea–inland gradient.Methods: Five habitat types were surveyed along a sea–inland transect at seven sites along a climatic gradient in Portugal. A multistep framework, considering the relevant scales and gradients, provided standardised scores of species co-occurrence (based on presence/absence and abundance data) for the whole study area and along the climatic and sea–inland gradients.Results: Species diversity was primarily related to the local sea–inland gradient. Co-occurrence analyses indicated the prevalence of species segregation, suggesting competition and species sorting across sites. Within each site, segregation prevailed, but tendencies for species aggregation were observed in some habitat types.Conclusions: To our knowledge, this is the first study evaluating species co-occurrences considering all habitat types within the whole dune ecosystem, analysing presence/absence and abundance data against regional and local gradients. Results converge with refined theories of community assembly, constituting added values for assessing multiscalar co-occurrence patterns of plant communities, and thus improving reporting of the condition of dune habitats and biodiversity.

description: Bifurcations in kinetic pathways decide the evolution of a system. An example is crystallization, in which the thermodynamically stable polymorph may not form due to kinetic hindrance. Here, we use confined self-assembly to investigate the interplay of thermodynamics and kinetics in the crystallization pathways of finite clusters. We report the observation of decahedral clusters from colloidal particles in emulsion droplets and show that these decahedral clusters can be thermodynamically stable just like icosahedral clusters. Our hard sphere simulations reveal how the development of the early nucleus shape passes through a bifurcation that decides the cluster symmetry. A geometric argument explains why decahedral clusters are kinetically hindered and why icosahedral clusters can be dominant even if they are not the thermodynamic ground state.

description: MOFs are a class of crystalline inorganicorganic
 hybrid porous materials which show
 large surface areas, high porosity and easy
 chemical tunability. The MOFs are produced by
 a coordination reaction between metal clusters
 and organic ligands.1 The interest on these
 compounds is mainly due to the outstanding
 physical properties they show, which allow
 them to access many different uses of
 applications (gas separation, catalysis,
 biomedical imaging etc).2 MOF-801 and MOF-
 808 are two Zr-based MOFs which have shown
 a high chemical stability. Therefore, we have
 studied the adsorption capacity of both
 compounds towards the adsorption of Cr(VI)
 from water.

description: Background: An understanding of the effects of red deer on bryophyte and lichen communities in wet heath and bog vegetation typical of northwest Scotland is important so that land managers can make more informed decisions concerning deer numbers.Aims: To compare various measures of cryptogam species diversity inside and outside a number of established deer exclosures at the Letterewe and Little Gruinard estates, Wester Ross, Scotland.Methods: Species cover data were recorded from 192 2 m × 2 m quadrats allocated to 32 blocks and assigned to nine exclosures of different ages with due attention to randomisation. Linear mixed effects models were fitted to the data.Results: In the short to medium term there was no significant difference in cryptogam dominance, diversity and species richness on either side of the exclosures. However, Cladonia lichens responded to a lack of trampling and were significantly more abundant inside exclosures. Greater Calluna vulgaris cover in the absence of a large herbivore is likely to have created conditions that promote the growth of Sphagnum capillifolium ssp. rubellum and this in turn increased the habitat available for several liverworts.Conclusions: The upper limit of deer numbers deemed appropriate for reducing loss of Calluna cover in wet heath vegetation is set too high to prevent impact on important cryptogam communities.

description: In this paper, we consider multi-objective optimization problems with a sparsity constraint on the vector of variables. For this class of problems, inspired by the homonymous necessary optimality condition for sparse single-objective optimization, we define the concept of L-stationarity and we analyze its relationships with other existing conditions and Pareto optimality concepts. We then propose two novel algorithmic approaches: the first one is an Iterative Hard Thresholding method aiming to find a single L-stationary solution, while the second one is a two-stage algorithm designed to construct an approximation of the whole Pareto front. Both methods are characterized by theoretical properties of convergence to points satisfying necessary conditions for Pareto optimality. Moreover, we report numerical results establishing the practical effectiveness of the proposed methodologies.

description: Lattice QCD spectra can be used to constrain partial-wave scattering amplitudes that, while satisfying unitarity, do not have to respect crossing symmetry and analyticity. This becomes a particular problem when extrapolated far from real energies, e.g. in the case of broad resonances like the $σ$, leading to large systematic uncertainties in the pole position. In this manuscript, we will show how dispersion relations can implement the additional constraints, using as input lattice--determined $ππ$ partial-wave scattering amplitudes with isospin--0,1,2. We will show that only certain combinations of amplitude parameterizations satisfy all constraints, and that when we restrict to these, the $σ$ pole position is determined with minimal systematic uncertainty. The evolution of the now well-constrained $σ$ pole with varying light quark mass is presented, showing how it transitions from a bound-state to a broad resonance.

description: Traveling modulating pulse solutions consist of a small amplitude pulse-like envelope moving with a constant speed and modulating a harmonic carrier wave. Such solutions can be approximated by solitons of an effective nonlinear Schrodinger equation arising as the envelope equation. We are interested in a rigorous existence proof of such solutions for a nonlinear wave equation with spatially periodic coefficients. Such solutions are quasi-periodic in a reference frame co-moving with the envelope. We use spatial dynamics, invariant manifolds, and near-identity transformations to construct such solutions on large domains in time and space. Although the spectrum of the linearized equations in the spatial dynamics formulation contains infinitely many eigenvalues on the imaginary axis or in the worst case the complete imaginary axis, a small denominator problem is avoided when the solutions are localized on a finite spatial domain with small tails in far fields.

description: Gradient Ascent Pulse Engineering (GRAPE) is a popular technique in quantum optimal control, and can be combined with automatic differentiation (AD) to facilitate on-the-fly evaluation of cost-function gradients. We illustrate that the convenience of AD comes at a significant memory cost due to the cumulative storage of a large number of states and propagators. For quantum systems of increasing Hilbert space size, this imposes a significant bottleneck. We revisit the strategy of hard-coding gradients in a scheme that fully avoids propagator storage and significantly reduces memory requirements. Separately, we present improvements to numerical state propagation to enhance runtime performance. We benchmark runtime and memory usage and compare this approach to AD-based implementations, with a focus on pushing towards larger Hilbert space sizes. The results confirm that the AD-free approach facilitates the application of optimal control for large quantum systems which would otherwise be difficult to tackle.

description: ABSTRACTHow can we understand the European Union's responses to the euro area financial crisis? This contribution examines this question through a historical institutionalist (HI) lens. First it reviews the design of existing institutions. With the help of HI it examines what challenges the institutional design posed on the European Union (EU) when the crisis hit. Next, the responses to the crisis by member state leaders and by EU-level actors are reviewed. An analysis is made of selected new EU institutions created to address the crisis: the European Financial Stability Facility; the European Stability Mechanism; the Six-Pack and Two-Pack; the European Semester; and the Fiscal Compact. Four ideal types – ‘displacement’, ‘layering’, ‘drift’ and ‘conversion’ – are examined and found not to fit well. In some cases institutions were ‘layered’ on top of existing institutions. Perhaps an amendment could be made by offering the ideal type ‘copying’ in those cases where new institutions that borrow from earlier institutions. Although no complex problem can be truly understood by looking at it through one single theoretical lens, this contribution argues that a large of part of the problems that emerged, and the solutions adopted, can be understood by examining it through an HI lens.

description: Over the last decade, observations have shown that the mean mass of ultra-high-energy cosmic rays (UHECRs) increases progressively toward the highest energies. However, the precise composition is still unknown, and several theoretical studies hint at the existence of a subdominant proton component up to the highest energies. Motivated by the exciting prospect of performing charged-particle astronomy with ultra-high-energy (UHE) protons we quantify the level of UHE-proton flux that is compatible with present multimessenger observations and the associated fluxes of neutral messengers produced in the interactions of the protons. We study this scenario with numerical simulations of two independent populations of extragalactic sources and perform a fit to the combined UHECR energy spectrum and composition observables, constrained by diffuse gamma-ray and neutrino observations. We find that up to of order $10\%$ of the cosmic rays at the highest energies can be UHE protons, although the result depends critically on the selected hadronic interaction model for the air showers. Depending on the maximum proton energy ($E_\text{max}^\text{p}$) and the redshift evolution of sources, the associated flux of cosmogenic neutrinos and UHE gamma rays can significantly exceed the multimessenger signal of the mixed-mass cosmic rays. Moreover, if $E_\text{max}^\text{p}$ is above the GZK limit, we predict a large flux of UHE neutrinos above EeV energies that is absent in alternate scenarios for the origin of UHECRs. We present the implications and opportunities afforded by these UHE proton, neutrino and photon fluxes for future multimessenger observations.

description: Background: Biodiversity is perceived to decline from lowlands towards mountain peaks and away from the Equator towards the Poles, but supporting data for most groups of organisms are lacking, especially at the local scale.Aims: Elevational gradients of fern species richness in tropical forest habitats were analysed to test the hypotheses that fern species composition patterns were similar between elevational gradients, that total species richness of complete elevational gradients gradually declined due to changing climatic conditions with increasing distance from the Equator, and that the elevation of highest species richness gradually declined with increasing latitude.Methods: We used plot-based elevational fern species richness surveys compiled from recent field work and own published studies, between 18° N and 18° S along the Andean mountain range, and compared the transects of patterns of species richness and composition, and distribution of taxa.Results: Taxonomic composition was highly similar among tropical regions. Elevational richness patterns were symmetrically hump-shaped and overall richness was virtually equal along most of the tropical latitudinal gradient. In contrast, the subtropical localities at the edges of our study area, ca. 18° N and 18° S, showed strikingly different patterns from those in the tropical zone.Conclusions: Within the tropics, there appears to be no latitudinal diversity gradient of ferns at the local scale. We suggest that, in tropical habitats, species richness of ferns at the local scale is limited by the number of species that can co-occur and that the available niche space is saturated.
title: Studies on the adhesive factors of pathogenic strains of escherichia coli isolated from man
Creators: name: Quintana, ARC
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1981

description: The present study was designed to answer a number of questions related to the presence and function of known or suspected adhesive factors in strains of E.coli. A total of 808 E.coli strains isolated from intestinal and extraintestinal sources in man were tested for the ability to agglutinate human, calf and guinea-pig RBC in the presence and absence of D-mannose, and for the presence of CFA/I and CFA/II by slide agglutination and immunodiffusion techniques using specific antisera. The biochemical and serological characteristics of CFA/I and CFA/II positive strains were examined, and related to the genetic control of these adhesive factors. The morphological characteristics of these fimbriate antigens was investigated by electron microscopy studies. Strains that did not possess CFA/I or CFA/II, but were able to cause MRHA of human and/or calf RBC, were further examined by serological methods for the presence of other adhesive factors. An in vitro assay using HEp-2 tissue culture cells was developed to test the adhesive ability of strains of E.coli able and unable to cause MPJLA or MSHA. The relationship between the biochemical and genetic characteristics of the E.coli strains and their ability to adhere to HEp-2 cells was also investigated.

description: Listeria monocytogenes, a Gram-positive opportunistic food-borne pathogen, naturally resistant to many antibiotics and acquired resistance may be a concern in the nearer future. Hence, there is a scope for screening of novel therapeutic agents and drug targets, toward the treatment of fatal listeria infections. The SecA homologs, SecA1 and SecA2 are the essential components of the general secretion (Sec) pathway, a specialised protein export system, present in L. monocytogenes. This study evaluates the use of botanicals against L. monocytogenes MTCC 1143 by considering SecA proteins as probable drug targets by high-throughput screening approaches. The 3D structure of SecA proteins with good stereochemical validity was generated by comparative modelling. The druglikeness and pharmacokinetic properties of 97 phytoligands identified through the extensive literature survey were predicted for druglikeness and ADMET properties. The inhibitory properties of best candidates were studied by molecular docking. The effect of the selected candidate molecules were further analysed in vitro well diffusion and cell aggregation assays. The antibiotic sensitivity profiling applied to L. monocytogenes MTCC 1143 using clinically relevant antibiotics showed that the bacteria became drug resistant to many tested antibiotics. The virtual screening suggested that .05 M cinnamic aldehyde from Cinnamomum camphora and 1, 2-Epoxycyclododecane from Cassia auriculata were identified as potential SecA inhibitors. The well diffusion assays suggested that the selected herbal substances have antibacterial activities. Further, preliminary validation suggested that incorporation of cinnamic aldehyde and methanolic or ethyl acetate extract of C. auriculata in broth medium shows growth reduction, misassembly and cell aggregation. This indicates the inhibition of SecA targets.

description: This thesis is a study of the public education system of the Northern Territory for the period 1876 to 2010, in part through first-hand accounts of the events and challenges as experienced by educators who taught in the system, especially since 1960. The study substantiates the narratives of the educator’s lives and work against Commonwealth and Territory reviews and reports, including Annual Northern Territory Department of Education Reports and explores available literature, to provide details of the evolving system throughout the last 134 years. The narratives and literature combine and reflect a view of events that shaped the public education system. The research aims to understand how the unusual characteristics of the NT in terms of geographical, political and demographical events have impacted on the development of the Northern Territory public education system during a one hundred and thirty three year history to 2010. In essence, this research aims to capture a sense of these times in a place that has seen tremendous educational change and growth amidst considerable political, economic and social development. By examination of this extended period, the historical background which informs the development of education in the Northern Territory can be used to illuminate contemporary events. The research finds that the Northern Territory public education system has been a system that has tried to adapt to changing circumstances, but in fact continues to reinvent itself, with little consideration and acknowledgement for corporate history. Although the system has developed in terms of infrastructure; little progress has been made to develop a quality system.

description: Abstract: You are the spark within the infinite, The material of Stars. Consciousness as the universe’s mirror. Your head is your cognitive mind, giving you the ability to reason, question, and analyze. Your heart is your emotional center, where empathy, compassion, and intuition reside. Your hand is your action, the bridge between inner transformation and outer change. To evolve holistically, these three must be in balance, becoming a conscious force for good in the world. The individual is a microcosm of the entire universe. The work of evolving the world is inseparable from the work of evolving the self. Conscious evolution is our responsibility. We are not passive observers. We are co-creators. Our thoughts shape culture. Our emotions shape relationships. Our actions shape history. In this practice there is no final destination. Only an ongoing unfolding. We move from scarcity to wholeness. We live in a world that constantly tells us we are not enough. Not smart enough. Not attractive enough. Not successful enough. This is the mindset of scarcity—rooted in separation and fear. But scarcity is an illusion born from forgetting who we are. Wholeness arises when we recognize that every part of us belongs. Healing comes not from erasing what we dislike, but from integrating it. From allowing the Head, Heart, and Hand to work together, not in opposition. From this place of inner harmony, we filter our thoughts, emotions, and behaviors not through fear or ego, but through consciousness we become Deliberate. Purposeful. Present. Here are simple ways to begin evolving consciously.

1. Reflect daily. 2. Ground in nature. 3. Educate your head. 4. Educate your heart. 5. Activate your hand. 6. Create rituals of meaning. 7. Join or Build communities. The universe has spent billions of years creating a being who can love, learn, and lead. Now that you are here, what will you do? The choice is yours.
Designing and building a children’s bamboo & hemp playground

description: A course named “Building with Bamboo” is part of the final year curriculum of the building engineer at Avans University Tilburg, AB&I, department of architecture. Within this course students can earn 2x3 E.C. over a period 2x10 days. From September 2015 up to January 2016 the subject of the course involved the designing and building of a children’s playground made of bamboo and hemp. The playground is situated in Antwerp (Belgium) on the inner courtyard of an elementary school for children between 6 and 12 years of age. This particular school attracts a high number of children who do not speak Dutch as a native language. To help establish a better and faster communication with them, the children were invited to come up with ideas for their new playground. These ideas were transformed into 6 proposals by our building engineer students, and put on display at the elementary school. One design, chosen by the children and their parents, was picked out. Prior to execution our students prepared IKEA-like manuals to involve the children of the primary school in the construction of their bamboo playground as much as possible. Parts of the playground were prefabricated and a mock-up was made with the help of the children. Eventually the playground, a 3-dimentional labyrinth made out of bamboo and hemp measuring 5x5x5m, was erected in 4 days by 39 students. Protection methods against decay due to sun and moisture exposure were implemented. Special care has been given to the foundation of the bamboo poles and to lashing techniques used for connecting the bamboo pole structure. A maintenance manual has been given to the teachers of the elementary school. A follow up to study the decay of bamboo and hemp, being expose to a West-European climate, was planned.

description: For the characterization of friction conditions under sheet metal forming process conditions, different friction test set-ups are being used in industry. However, different friction tests and test set-ups are known to result in scattering friction results. In this work, the TriboForm software is utilized to numerically model the frictional behavior. The simulated coefficients of friction are experimentally validated using friction results from a standardized strip drawing friction test set-up. The experimental and simulation results of the friction behavior show a good overall agreement. This demonstrates that the TriboForm software enables simulating friction conditions for varying tribology conditions, i.e. resulting in a generally applicable approach for friction characterization under industrial sheet metal forming process conditions.

description: Ways to define «corruption and fraud» are endless, so the application of
constitutional criminal law may be impaired. The communication and public comment
and politics are sometimes done in terms profoundly mistaken. Recently, in Portugal,
prominent politicians and commentators have come to call the «criminalization of
illicit enrichment» (embezzlement) even if it was at the sacrifice of the Constitution or
the rule of law. It is democracy that happens to be in danger. At the same time it
defends itself with almost theological fanaticism the capitalist economic system,
seeking to enshrine in law its destruction. That is, there is a certain political
demagoguery that wants to have everything at the same time as if that were
possible. Given this, it remains to ordinary act if necessary under the scope of
defenses and making use of the constitutional right of resistance.

description: This paper investigates the performance of a lowcost Throttle-by-Wire-System (TbWS) for two-wheeler applications. Mopeds/scooters are still restricted environmentally harmful. Throttle-by-Wire-Systems can contribute to environmental protection by replacing conventional restrictors. Its consisting of an anisotropic magnetoresistance (AMR) throttle position sensor and a position controlled stepper motor driven throttle valve actuator. The decentralized throttle position sensor is operating contactless and acquires redundant data. Throttle valve actuation is realized through a position controlled stepper motor, sensing its position feedback by Hall effect. Using a PI-controller, the stepper motors position is precisely set. Both units are transceiving data by a CAN bus. Furthermore, fail-safe functions, plausibility checks, calibration algorithms and energy saving modes have been implemented. Both modules have been evaluated by Hardware-in-the-Loop testing in terms of reliability and measuring/positioning performance before the system was integrated into a Peugeot Kisbee 50 4T (Euro 5/injected). Finally, the sensor unit comes with a measurement deviation of less than 0.16% whereas the actuator unit can approach throttle valve positions with a deviation of less than 0.37%. The actuators settling time does not exceed 0.13s while stable, step-loss free and noiseless operation.

description: This thesis is dedicated to the catalytic conversion of the different isomers of methyl pentenoate as bio renewable resource that can be produced from lignocellulosic biomass. This substrate has been tested in the Rh-catalysed hydroformylation, Rh-catalyzed hydroaminomethylation and Pd-catalyzed alkoxycarbonylation. The corresponding reaction products can act as platform chemicals for the synthesis of different monomers for polyamide and polyester synthesis. Additionally, some work has been conducted on the hydroformylation of 1,2,4-trivinylcyclohexane as an unuasual olefin.

description: We produce a simple group $G$ of cardinality $\aleph_1$ which is Artinian (every strictly descending chain of subgroups is finite), satisfies a Burnside law and such that for each uncountable subset $Y \subseteq G$ there exists a natural number $n_Y$ for which every element of $G$ may be expressed as a product of length at most $n_Y$ of elements in $Y^{\pm 1}$.
 In particular this group is Jónsson (every proper subgroup is of strictly smaller cardinality) and strongly bounded (every abstract action on a metric space has bounded orbits); this is the first example of an uncountable group having both of these properties which is constructed without using the continuum hypothesis. The group $G$ can also be made so that all subgroups are simple and all nontrivial subgroups are malnormal in $G$.

description: Binary neutron stars (BNSs) and neutron star--black hole (NSBH) binaries are two of the most promising gravitational wave (GW) sources to probe matter effects. Upcoming observing runs of LIGO-Virgo-KAGRA detectors and future third generation detectors like Einstein Telescope and Cosmic Explorer will allow the extraction of detailed information on these matter effects from the GW signature of BNS and NSBH systems. One subtle effect which may be helpful to extract more information from the detection of compact binary systems is the nonlinear memory. In this work, we investigate the observational consequences of gravitational wave nonlinear memory in the presence of matter effects. We start by quantifying the impact of nonlinear memory on distinguishing BNS mergers from binary black holes (BBHs) or NSBH mergers. We find that for the third generation detectors, the addition of nonlinear memory to the GW signal model expands the parameter space where BNS signals become distinguishable from the BBH and NSBH signals. Using numerical relativity simulations, we also study the nonlinear memory generated from the postmerger phase of BNS systems. We find that it does not show a strong dependence on the equation of state of the NS. However, the amplitude of nonlinear memory from the BNS postmerger phase is much lower than the one from BBH systems of the same masses. Furthermore, we compute the detection prospects of nonlinear memory from the postmerger phase of NS systems by accumulating signal strength from a population of BNS mergers for the current and future detectors. Finally, we discuss the impact of possible linear memory from the dynamical ejecta of BNS and NSBH systems and its signal strength relative to the nonlinear memory. We find that linear memory almost always has a much weaker effect than nonlinear memory.
A comparative study on the interaction of the putative anticancer alkaloids, sanguinarine and chelerythrine, with single- and double-stranded, and heat-denatured DNAs

description: A detailed investigation on the interaction of two benzophenanthridine alkaloids, sanguinarine (SGR) and chelerythrine (CHL), with the double-stranded (ds), heat-denatured (hd), and single-stranded (ss) DNA was performed by spectroscopy and calorimetry techniques. Binding to the three DNA conformations leads to quenching of fluorescence of SGR and enhancement in the fluorescence of CHL. The binding was cooperative for both of the alkaloids with all the three DNA conformations. The binding constant values of both alkaloids with the ds DNA were in the order of 106 M−1; binding was weak with hd and much weaker to the ss DNA. The fluorescence emission of the alkaloid molecules bound to the ds and hd DNAs was quenched much less compared to those bound to the ss DNA based on competition with the anionic quencher KI. For both double stranded and heat denatured structures the emission of the bound alkaloid molecules was polarized significantly and strong energy transfer from the DNA bases to the alkaloid molecules occurred. Intercalation of SGR and CHL to ds, hd, and ss DNA was proved from these fluorescence results. Calorimetric studies suggested that the binding to all DNA conformations was both enthalpy and entropy favored. Both the alkaloids preferred double-helical regions for binding, but SGR was a stronger binder than CHL to all the three DNA structures.

description: The rapid development of information and communications technology has enabled the use of digital-controlled and software-driven distributed energy resources (DERs) to improve the flexibility and efficiency of power supply, and support grid operations. However, this evolution also exposes geographically-dispersed DERs to cyber threats, including hardware and software vulnerabilities, communication issues, and personnel errors, etc. Therefore, enhancing the cyber-resiliency of DER-based smart grid - the ability to survive successful cyber intrusions - is becoming increasingly vital and has garnered significant attention from both industry and academia. In this survey, we aim to provide a systematical and comprehensive review regarding the cyber-resiliency enhancement (CRE) of DER-based smart grid. Firstly, an integrated threat modeling method is tailored for the hierarchical DER-based smart grid with special emphasis on vulnerability identification and impact analysis. Then, the defense-in-depth strategies encompassing prevention, detection, mitigation, and recovery are comprehensively surveyed, systematically classified, and rigorously compared. A CRE framework is subsequently proposed to incorporate the five key resiliency enablers. Finally, challenges and future directions are discussed in details. The overall aim of this survey is to demonstrate the development trend of CRE methods and motivate further efforts to improve the cyber-resiliency of DER-based smart grid.

description: Ramanujan's last letter to Hardy introduced the world to mock theta functions, and the mock theta function identities found in Ramanujan's lost notebook added to their intriguing nature. For example, we find the four tenth-order mock theta functions and their six identities. The six identities themselves are of a spectacular nature and were first proved by Choi. We also find over eight sixth-order mock theta functions in the lost notebook, but among their many identities there is only one relationship like those of the tenth-orders. Recently, three new identities for the sixth-order mock theta functions that are in the spirit of the six tenth-order identities were discovered. Here we present several families of tenth-order like identities for Appell functions, which are the building blocks of Ramanujan's mock theta functions.
