description: We prove several finiteness results for the class $M_{a,b,G,n}$ of $n$-manifolds that have fundamental groups isomorphic to $G$ and that can be given complete Riemannian metrics of sectional curvatures within $[a,b]$ where $a\le b<0$. In particular, if $M$ is a closed negatively curved manifold of dimension at least three, then only finitely many manifolds in the class $M_{a,b,π_1(M), n}$ are total spaces of vector bundles over $M$. Furthermore, given a word-hyperbolic group $G$ and an integer $n$ there exists a positive $ε=ε(n,G)$ such that the tangent bundle of any manifold in the class $M_{-1-ε, -1, G, n}$ has zero rational Pontrjagin classes.

description: We study the Brauer classes rising from the obstruction to the existence of tautological line bundles on the Picard scheme of curves. We establish various properties of the Brauer classes for families of smooth curves. We compute the period and index of the Brauer class associated with the universal smooth curve for a fixed genus. We also show such Brauer classes are trivialized when we specialize to certain generalized theta divisors. If we consider the universal totally degenerate curve with a fixed dual graph, using symmetries of the graph, we give bounds on the period and index of the Brauer classes. As a result, we provide some division algebras of prime degree, serving as candidates for the cyclicity problem. As a byproduct, we re-calculate the period and index of the Brauer class for universal smooth genus g curve in an elementary way. We study certain conic associated with the universal totally degenerate curve with a fixed dual graph. We show the associated conic is non-split in some cases. We also study some other related geometric properties of Brauer groups.

description: We analyze the contributions of the one-pion-pole (OPP) exchange, caused by strong low-energy interactions, and the pseudoscalar interaction beyond the Standard Model (BSM) to the correlation coefficients of the neutron beta-decays for polarized neutrons, polarized electrons and unpolarized protons. The strength of contributions of pseudoscalar interactions is defined by the effective coupling constant C_ps = C^(OPP)_ps + C^(BSM)_ps. We show that the contribution of the OPP exchange is of order C^(OPP)_ps ~ - 10^(-5). The effective coupling constant C^(BSM)_ps of the pseudoscalar interaction BSM can be in principle complex. Using the results, obtained by Gonzalez-Alonso et al.( Prog. Part. Nucl. Phys. 104, 165 (2019)) we find that the values of the real and imaginary parts of the effective coupling constant C^(BSM)_ps are constrained by - 3.5x10^{-5} < ReC^(BSM)_ps < 0 and ImC^(BSM)_ps < - 2.3x10^(-5), respectively. The obtained results can be used as a theoretical background for experimental searches of contributions of interactions BSM in asymmetries of the neutron beta-decays with a polarized neutron, a polarized electron and an unpolarized proton at the level of accuracy of a few parts of $10^{-5}$ or even better (Abele, Hyperfine Interact.237, 155 (2016)).

description: Given a knot K in the 3-sphere, consider a singular disk bounded by K and the intersections of K with the interior of the disk. The absolute number of intersections, minimised over all choices of singular disk with a given algebraic number of intersections, defines the framing function of the knot. We show that the framing function is symmetric except at a finite number of points. The symmetry axis is a new knot invariant, called the natural framing of the knot. We calculate the natural framing of torus knots and some other knots, and discuss some of its properties and its relations to the signature and other well-known knot invariants.

description: The global climate change agreement completed on December 12, 2015 in Paris set a collective target to cap greenhouse gas emissions in order to limit the temperature increase to 2 degrees Celsius with a goal to get as close as possible to 1.5 degrees above pre-industrial levels. These goals were to be accomplished through a “bottom up” mechanism for national policy approaches in which states made their own choices about how they would meet climate targets. This paper examines why and how an agreement was possible in 2015 when it had not been before. What was different in Paris, or leading up to Paris, so that the parties involved successfully came to an agreement when it was not possible in Copenhagen? This paper presents a problem definition and issue framing perspective to examine the shift in the discussion in Paris from the burdens of climate action to opportunities climate action offered for economic and development models. It provides a road map to understand the role of key stakeholders, including governments, the business community, civil society, and subnational actors in the making of the climate agreement.
Brain responses to contrastive and noncontrastive morphosyntactic structures in African American English and Mainstream American English: ERP evidence for the neural indices of dialect

description: Recent research has shown that distinct event-related potential (ERP) signatures are associated with switching between languages compared to switching between dialects or registers (e.g., Khamis-Dakwar & Froud, 2007; Moreno, Federmeier & Kutas, 2002). The current investigation builds on these findings to examine whether contrastive and non-contrastive morphosyntactic features in English elicit differing neural responses in bidialectal speakers of African American English (AAE) and Mainstream American English (MAE), compared to monodialectal speakers of MAE. Event-related potentials (ERPs) and behavioral responses (response types and reaction time) to grammaticality judgments targeting a contrasting morphosyntactic feature between MAE and AAE are presented as evidence of dual-language representation in bidialectal speakers. Results from 30 participants (15 monodialectal; 15 bidialectal) support the notion that bidialectal populations demonstrate distinct neurophysiological profiles from monolingual groups as indicated by a significantly greater P600 amplitude from 500ms – 800ms time window in the monodialectal group, when listening to sentences containing contrasting features. Such evidence can support the development of linguistically informed educational curriculums and clinical approaches from speech-language pathologists, by elucidating the differing underlying processes of language between monodialectal and bidialectal speakers of American English.
(Too) many policies under one roof? About the integration of competition law enforcement and sectoral regulation within one authority
Creators: name: Piszcz, Anna
Publisher: name: Market and Competition Law Review
Year: 2024

description: The traditional institutional model of a competition agency has assumed entrusting competition protection to a single authority. Over time, more and more often national competition authorities are being entrusted not only with competition enforcement but also with other functions (tasks). And the tendency to increasingly entrust competition authorities with additional roles not related to competition policy may seem worrying, as there may be a risk of pushing competition protection to the background. This article is going to reflect upon the relevant changes after the enlargement of the European Union (2004) and the current situation of selected competition authorities in this context. This contribution will explore the topic in relation to the main models of multifunctional competition authorities entrusted with sectoral regulation and examine authorities which combine competition enforcement with sectoral regulation in infrastructure industries. The article will also take into account that public enforcement of the prohibition of unfair trading practices provided for in Directive 2019/633 (“UTP Directive”), and limited to the agri-food market, was assigned to competition authorities (in line with the European Commission’s suggestion), which is the case of almost half of the EU Member States. It will attempt at the identification of advantages and disadvantages of entrusting competition authorities with additional sectoral regulation functions and discuss whether Directive 2019/1 (“ECN+ Directive”) may serve as a cure for disadvantages of adding not related objectives, such as overwhelming numbers of tasks and lacking resources, including human resources or a relatively small part of budget dedicated to competition enforcement. The research methods employed in this article include, first, a doctrinal legal method, second, systemic and teleological approaches, and, last, a comparative analysis.

description: MR-STAT is a recently proposed framework that allows the reconstruction of multiple quantitative parameter maps from a single short scan by performing spatial localisation and parameter estimation on the time domain data simultaneously, without relying on the FFT. To do this at high-resolution, specialized algorithms are required to solve the underlying large-scale non-linear optimisation problem. We propose a matrix-free and parallelized inexact Gauss-Newton based reconstruction algorithm for this purpose. The proposed algorithm is implemented on a high performance computing cluster and is demonstrated to be able to generate high-resolution ($1mm \times 1mm$ in-plane resolution) quantitative parameter maps in simulation, phantom and in-vivo brain experiments. Reconstructed $T_1$ and $T_2$ values for the gel phantoms are in agreement with results from gold standard measurements and for the in-vivo experiments the quantitative values show good agreement with literature values. In all experiments short pulse sequences with robust Cartesian sampling are used for which conventional MR Fingerprinting reconstructions are shown to fail.

subject: aesthetic understanding of water

description: With the rise in industrial capitalism during the 20th Century, artists increasingly focused on the threat of a disappearing natural world. In the high technology era of the late 20th Century, artists whose practice is termed 'ecological' based their work around new understandings of the relationship between nature and culture, fundamentally underpinned by a shift toward evolutionary, systems-theoretical perspectives from those of conquest and exploitation. Now, at the dawn of the 21st Century, the information era has brought into intersection the discourses of information technologies, quantum physics, and biological science, awakening artists to the challenge of engaging with ecology as the primary subject of their practice. The doctoral project that is the subject of this exegesis focuses critical attention on our scientific and aesthetic understandings of water - a crucial symbolic element of global import in survival. It explores the representation of water in and through art practice that is informed by political ecological awareness and new (digital) technologies. My practice exploits the potential of recent digital technologies to create experiences that aim to encourage a more ecologically sustainable human engagement with nature through this focus on water. This exegesis describes and locates the creative work within an ongoing discourse in contemporary culture that actively seeks to re-establish and redefine the relationship between culture and nature.

Not “big is bad” but “closed is bad”? Exploring dynamic competition in generative AI

description: Scholars have seized upon studies on economic concentration to revive the idea that “big is bad”. A recent addition to the literature, by James Bessen, shares a concern for declining disruption rates but argues instead that “closed is bad”. We review this debate, concluding that neither fully grapples with the dynamic competition paradigm. The theory of dynamic competition offers important nuances to current understandings of competition, and in particular the role of innovation, which we illustrate via a case study of generative AI. We then turn to policy measures, and in particular those under the “unbundling” umbrella, i.e., breaking ties, mandating interoperability, and imposing data sharing. Each of these measures is finding its way into the EU policy framework. We show that, though such measures can make sense in specific circumstances, the challenges – both conceptual and practical – are not to be underestimated. We build on our generative AI case study to highlight the opportunities and risks involved, which confirm the desirability of a case-specific approach.

Branding the Power Center: Toponymy as a Tool for Assertion of Political Prowess

Subjects: Historic preservation
Toponymy

Street names

description: The urban environment is made up of separate elements that spatialize social, cultural, economic, historic information about the geography and the people interacting with it. Their recognition through the lens of history and historic knowledge is heritage. Toponymy, or the science of naming places, is one of those spatial elements, and street names are a subset of place-names. They are essential inheritances for a state and its people as the state transitions through social, political, and cultural epochs, as they present a capsule to look back at state values and mechanisms. However, as with every heritage element, there is a quotient of temporality to them. Since street names are cultural productions that represent the most relevant and useful cultural information about the state at the time of naming, as conditions of the state change, they are often reconfigured. India, having undergone various rules and regimes, has a long history of assigning and reassigning names to places not only as a way of commemorating important events, personalities and revolutionaries but also for reforming spatial narratives rife with political intents. However, in recent years, specifically under the regime of the current government, there has been a proliferation of place-name changes in various scales of urban spaces: cities, districts, streets, buildings, transit infrastructures. These reconfigurations have attracted vehement opposition by the media. However, recent media depictions have failed to take into account the broader significance of name changes (toponymy) and historical context of these changes. This thesis is an inquiry into the heritage value of street names, the naming mechanism, and the actors behind the processes, how the processes intersect with India’s political and historical contexts in an erstwhile colonial capital city of New Delhi in India, which also became the nucleus of the operation of Indian governments within the larger city of Delhi. Through a review of when and how street renaming happens in the area, identifying existing policies in place that facilitate the change, or are subverted to make it happen, the thesis aims to understand the mechanism itself. The thesis presents the information through the creation of layered historical maps to trace name changes through time, interviews with historians and other relevant stakeholders, and user interviews to better understand the current context of street name changes. The aim is to provide a timely reminder of the importance of street names and naming mechanisms as a heritage production process and help contextualize it within the larger considerations and motivations that were at play.

description: MILOCERA SWINHOE
(Figs 2, 64–67)
 Milocera Swinhoe, 1904. Type species: Milocera horaria Swinhoe (1904). Madagascar.
 Description
 Head. Chaetosemata extended. Antenna fasciculate, not bipectinate.
 Wings (Fig. 2). Often weakly falcate; ranging from off-white, through ochreous to red-brown.
 Male genitalia (Figs 64, 66). Uncus usually fairly narrow, pointed or truncated. Gnathos present. Valva divided; shape of costa and of sacculus varies; stout spine-like setae usually present.
 Pregenital abdomen of male. Sternum A3 with or without a patch of bristles medially. Sternum A8 with margin weakly emarginated in type species, ranging to bilobed in some other species and with curved hornlike octavals in others.
 Female genitalia (Figs 65, 67). Corpus bursae small and usually densely covered with spines (as in Platypepla), but spines absent in type species (horaria).
 Diagnosis. The type species, which occurs in Madagascar, differs in the structure of the genitalia from all other species of Milocera, notably in the shape of the valva (see Fig. 64). The valva of M. horaria does not bear stout setae, which differs from the situation in many species. In the female, the shape of the corpus bursae is small and round, typical of the Platypepla - group of genera, but it lacks the dense arrangement of spines found in other species of Milocera.
 Distribution. Afrotropical region north of 21°S, and Madagascar.
 Comments. The inclusion of species additional to the type species by Prout (1922, 1932, 1934), Herbulot (1973, 1989) and, particularly, Krüger (2001) is accepted here provisionally on grounds mainly of similarity in general appearance of the moths and, in particular, the weakly falcate shape of the forewings. An alternative approach would be to synonymize Milocera with Platypepla, thus expanding considerably the concept of this latter genus. The species of Platypepla (in the sense adopted here), however, form a monophyletic group based on characters from the wings and, particularly, of the male genitalia.
 Number of species. Twenty-six species are listed by Krüger (2001), 16 of which are new.

description: This paper introduces the unsupervised assignment flow that couples the assignment flow for supervised image labeling with Riemannian gradient flows for label evolution on feature manifolds. The latter component of the approach encompasses extensions of state-of-the-art clustering approaches to manifold-valued data. Coupling label evolution with the spatially regularized assignment flow induces a sparsifying effect that enables to learn compact label dictionaries in an unsupervised manner. Our approach alleviates the requirement for supervised labeling to have proper labels at hand, because an initial set of labels can evolve and adapt to better values while being assigned to given data. The separation between feature and assignment manifolds enables the flexible application which is demonstrated for three scenarios with manifold-valued features. Experiments demonstrate a beneficial effect in both directions: adaptivity of labels improves image labeling, and steering label evolution by spatially regularized assignments leads to proper labels, because the assignment flow for supervised labeling is exactly used without any approximation for label learning.

description: Gospel singing is a musically sophisticated and culturally influential vocal performance style. Yet, its pedagogy is often expressed through the lens of formal/classical training or a Contemporary Commercial Music (CCM) umbrella for all non-classical styles. This is problematic because classical training does not produce gospel singing, and most CCM styles are derivatives of the black vernacular singing practices that are foundational to gospel music. It follows that Gospel singing should be foundational to the study of CCM styles. However, in the absence of formal vocal training, little is known about how gospel singers actually develop and maintain healthy gospel singing voices. The purpose of this study is to explore with 12 professional gospel singers, their perceptions of how they have developed and maintain a vibrant and successful gospel singing voice and what role, if any, formal voice training played in that development. The exploration revealed that professional gospel singers are often not only formally trained, but gospel is a key part of their formal training. Their gospel upbringing taught them key cultural practices that both align with and expand the conversation around traditional, CCM, and the growing Gospel voice pedagogy. Their stories offer a different perspective about how gospel singers learn and how they should be taught.
“Interested parties” versus unlawful State aid. State of play in CJEU’s caselaw

Publisher: name: Market and Competition Law Review
Year: 2024

description: In case of unlawful State aid, Art. 24(2) of Regulation 2015/1589 guarantees the possibility to submit a complaint to “any interested party”. The preamble to Regulation 2015/1589 even encourages the submission of such claims. Interested parties are defined by Art. 1(h) of this Regulation as “any Member State and any person, undertaking or association of undertakings whose interests might be affected by the granting of aid, in particular the beneficiary of the aid, competing undertakings and trade associations”. The fact that an entity belongs to one of the categories indicated in this provision (e.g., beneficiary or trade associations) does not determine its status of interested party – a key factor is proving that the interests of a particular entity have been affected by the (potentially) unlawful aid. The concept has been developed in case law. Among many detailed issues in judgements delivered either on the basis of Regulation 2015/1589 or the preceding Regulation 659/1999, the CJEU has discussed conditions under which a status of interested party could be attributed to undertakings in no direct competition with a recipient of State aid. Special attention is drawn to a beneficiary of State aid as a potential “interested party” – this category of entities is mentioned in Art. 1(h) of Regulation 2015/1589, but a form that needs to be used in order to submit a complaint does not list a beneficiary as a subject entitled to submitting a complaint. The article presents a review of CJEU cases in this regard, and aims at defining the current state of interpretation of “interested party” that opens a gate for particular entities to submit a complaint.

description: An algorithm for the triangularization of a matrix whose graph is a directed acyclic graph, popularly known as dag, is presented. One of the algorithms for obtaining this special form has been given by Sargent and Westerberg. Their approach is practically good but sequential in nature and cannot be parallelised easily. In this work we present a parallel algorithm which is based on the observation that, if we find the transitive closure matrix of a directed acyclic graph, count the number of entries in each row, sort them in the ascending order of their values and rank them accordingly, we get a lower triangular matrix. We show that all these operations can be done using 3-d CD- PARBS(Complete Directed PARBS) in constant time. The same approach can be used for the block cases, producing the same relabelling as produced by Tarjan’s algorithm, in constant time. To the best of our knowledge, it is the first approach to solve such problems using directed PARBS.

Requirements on the event topology, such as photon and large-radius jet multiplicity result in less background than signal. We also estimated the sensitivity of our analysis and found that it has a better exclusion potential compared to the strongest existing search for the specific benchmark points considered here.

description: In the Aharonov-Bohm (AB) effect, a superposed charge acquires a detectable phase by enclosing an infinite solenoid, in a region where the solenoid's electric and magnetic fields are zero. Its generation seems therefore explainable only by the local action of gauge-dependent potentials, not of gauge-independent fields. This was recently challenged by Vaidman, who explained the phase by the solenoid's current interacting with the electron's field (at the solenoid). Still, his model has a residual non-locality: it does not explain how the phase, generated at the solenoid, is detectable on the charge. In this paper we solve this non-locality explicitly, by quantising the field. We show that the AB phase is mediated locally by the entanglement between the charge and the photons, like all electromagnetic phases. We also predict a gauge-invariant value for the phase difference at each point along the charge's path. We propose a realistic experiment to measure this phase difference locally, by partial quantum state tomography on the charge, without closing the interference loop.

description: In this thesis we describe the UQoRE method which supports database reverse engineering by using a data mining technique. Generally, Reverse Engineering methods work by using information extracted from data dictionaries, database extensions, application programs and expert users. The main differences between all these methods rely on the assumptions made on the a-priori knowledge available about the database (schema and constraints on attributes) as well as the user competence. Most of them are based on the attribute name consistency. This paper presents a method based on user queries. Queries are stored in a “Query Base” and our system mines this new source of knowledge in order to discover hidden links and similarity between database elements.

description: Nearly every service on the Internet relies on the Domain Name System (DNS), which translates a human-readable name to an IP address before two endpoints can communicate. Today, DNS traffic is unencrypted, leaving users vulnerable to eavesdropping and tampering. Past work has demonstrated that DNS queries can reveal a user's browsing history and even what smart devices they are using at home. In response to these privacy concerns, two new protocols have been proposed: DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT). Instead of sending DNS queries and responses in the clear, DoH and DoT establish encrypted connections between users and resolvers. By doing so, these protocols provide privacy and security guarantees that traditional DNS (Do53) lacks. In this paper, we measure the effect of Do53, DoT, and DoH on query response times and page load times from five global vantage points. We find that although DoH and DoT response times are generally higher than Do53, both protocols can perform better than Do53 in terms of page load times. However, as throughput decreases and substantial packet loss and latency are introduced, web pages load fastest with Do53. Additionally, web pages successfully load more often with Do53 and DoT than DoH. Based on these results, we provide several recommendations to improve DNS performance, such as opportunistic partial responses and wire format caching.

Massive 3-loop Feynman diagrams reducible to SC* primitives of algebras of the sixth root of unity

description: In each of the 10 cases with propagators of unit or zero mass, the finite part of the scalar 3-loop tetrahedral vacuum diagram is reduced to 4-letter words in the 7-letter alphabet of the 1-forms $Ω:=dz/z$ and $ω_p:=dz/ (λ^{-p}-z)$, where $λ$ is the sixth root of unity. Three diagrams yield only $ζ(Ω^3ω_0)=1/90π^4$. In two cases $π^4$ combines with the Euler-Zagier sum $ζ(Ω^2ω_3ω_0)=\sum_{m> n>0}(-1)^{m+n}/m^3n$; in three cases it combines with the square of Clausen's $Cl_2(π/3)=\Im ζ(Ωω_1)=\sum_{n>0}\sin(πn/3)/n^2$. The case with 6 masses involves no further constant; with 5 masses a Deligne-Euler-Zagier sum appears: $\Re ζ(Ω^2ω_3ω_1)= \sum_{m>n>0}(-1)^m\cos(2πn/3)/m^3n$. The previously unidentified term in the 3-loop rho-parameter of the standard model is merely $D_3=6ζ(3)-6 Cl_2^2(π/3)-{1/24}π^4$. The remarkable simplicity of these results stems from two shuffle algebras: one for nested sums; the other for iterated integrals. Each diagram evaluates to 10 000 digits in seconds, because the primitive words are transformable to exponentially convergent single sums, as recently shown for $ζ(3)$ and $ζ(5)$, familiar in QCD. Those are SC$^*(2)$ constants, whose base of super-fast computation is 2. Mass involves the novel base-3 set SC$^*(3)$. All 10 diagrams reduce to SC$^*(3)\cup$SC$^* (2)$ constants and their products. Only the 6-mass case entails both bases.

description: The Standard Model violates parity, but only by mechanisms which are invisible to Large Hadron Collider (LHC) experiments (on account of the lack of initial state polarisation or spin-sensitivity in the detectors). Nonetheless, new physical processes could potentially violate parity in ways which are detectable by those same experiments. If those sources of new physics occur only at LHC energies, they are untested by direct searches. We probe the feasibility of such measurements using approximately 0.2 inverse femtobarns of data which was recorded in 2012 by the CMS collaboration and made public within the CMS Open Data initiative. In particular, we test an inclusive three-jet event selection which is primarily sensitive to non-standard parity violating effects in quark-gluon interactions. Within our measurements, no significant deviation from the Standard Model is seen and no obvious experimental limitations have been found. We discuss other ways that searches for non-standard parity violation could be performed, noting that these would be sensitive to very different sorts of models to those which our measurements constrain. We hope that our initial studies provide a valuable starting point for rigorous future analyses using the full LHC datasets at 13 TeV with a careful and less conservative estimate of experimental uncertainties.

 Hispophora was placed immediately after Hypotephrina (see above) in Janse’s treatment of the South
 African Ennominae. As for that genus, we find no reason to place Hispophora in the Macariini.

description: Two-dimensional Graphene is fascinating because of its unique electronic properties. From a fundamental perspective, one among them is the geometric phase structure near the Dirac points in the Brillouin zone, owing to the SU(2) nature of the Dirac cone wave functions. We ask if there are geometric phase structures in two dimensions which go beyond that of a Dirac cone. Here we write down a family of three-band continuum models of non-interacting fermions which have more intricate geometric phase structures. This is connected to the SU(3) nature of the wavefunctions near three-fold degeneracies. We also give a tight-binding free fermion model on a two-dimensional Graphene-like lattice where the three-fold degeneracies are realized at fine-tuned points. Away from them, we obtain new "three-band" Dirac cone structures with associated non-standard Landau level quantization, whose organization is strongly affected by the non-SU(2) or beyond-Dirac geometric phase structure of the fine-tuned points.

Diagonalizing operators over continuous fields of C*-algebras

description: It is well known that in the commutative case, i.e. for $A=C(X)$ being a commutative C*-algebra, compact selfadjoint operators acting on the Hilbert C*-module $H_A$ (= continuous families of such operators $K(x)$, $x\in X$) can be diagonalized if we pass to a bigger W*-algebra $L^\infty(X)={\bf A} \supset A$ which can be obtained from $A$ by completing it with respect to the weak topology. Unlike the "eigenvectors", which have coordinates from $\bf A$, the "eigenvalues" are continuous, i.e. lie in the C*-algebra $A$. We discuss here the non-commutative analog of this well-known fact. Here the "eigenvalues" are defined not uniquely but in some cases they can also be taken from the initial C*-algebra instead of the bigger W*-algebra. We prove here that such is the case for some continuous fields of real rank zero C*-algebras over a one-dimensional manifold and give an example of a C*-algebra $A$ for which the "eigenvalues" cannot be chosen from $A$, i.e. are discontinuous. The main point of the proof is connected with a problem on almost commuting operators. We prove that for some C*-algebras if $h\in A$ is a selfadjoint, $u\in A$ is a unitary and if the norm of their commutant $[u,h]$ is small enough then one can connect $u$ with the unity by a path $u(t)$ so that the norm of $[u(t),h]$ would be also small along this path.

description: Acridid grasshoppers (Orthoptera:Acrididae) are widely used model organisms for developmental, evolutionary, and neurobiological research. Although there has been recent influx of orthopteran transcriptomic resources, many use pooled ontogenetic stages obscuring information about changes in gene expression during development. Here we developed a de novo transcriptome spanning 7 stages in the life cycle of the acridid grasshopper Chorthippus biguttulus. Samples from different stages encompassing embryonic development through adults were used for transcriptomic profiling, revealing patterns of differential gene expression that highlight processes in the different life stages. These patterns were validated with semi-quantitative RT-PCR. Embryonic development showed a strongly differentiated expression pattern compared to all of the other stages and genes upregulated in this stage were involved in signaling, cellular differentiation, and organ development. Our study is one of the first to examine gene expression during post-embryonic development in a hemimetabolous insect and we found that only the fourth and fifth instars had clusters of genes upregulated during these stages. These genes are involved in various processes ranging from synthesis of biogenic amines to chitin binding. These observations indicate that post-embryonic ontogeny is not a continuous process and that some instars are differentiated. Finally, genes upregulated in the imago were generally involved in aging and immunity. Our study highlights the importance of looking at ontogeny as a whole and indicates promising directions for future research in orthopteran development.
