description: We compute at strong coupling the large N correlation functions of supersymmetric Wilson loops in large representations of the gauge group with local operators of N=4 super Yang-Mills. The gauge theory computation of these correlators is performed using matrix model techniques. We show that the strong coupling correlator of the Wilson loop with the stress tensor computed using the matrix model exactly matches the semiclassical computation of the correlator of the 't Hooft loop with the stress tensor, providing a non-trivial quantitative test of electric-magnetic duality of N=4 super Yang-Mills. We then perform these calculations using the dual bulk gravitational picture, where the Wilson loop is described by a "bubbling" geometry. By applying holographic methods to these backgrounds we calculate the Wilson loop correlation functions, finding perfect agreement with our gauge theory results.

description: At very high energies we expect that the hadronic cross sections satisfy the Froissart bound, which is a well-established property of the strong interactions. In this energy regime we also expect the formation of the Color Glass Condensate, characterized by gluon saturation and a typical momentum scale: the saturation scale $Q_s$. In this paper we show that if a saturation window exists between the nonperturbative and perturbative regimes of Quantum Chromodynamics (QCD), the total cross sections satisfy the Froissart bound. Furthermore, we show that our approach allows us to describe the high energy experimental data on $pp/p\bar{p}$ total cross sections.

description: Judging whether an integer can be divided by prime numbers such as 2 or 3 may appear trivial to human beings, but can be less straightforward for computers. Here, we tested multiple deep learning architectures and feature engineering approaches on classifying integers based on their residues when divided by small prime numbers. We found that the ability of classification critically depends on the feature space. We also evaluated Automated Machine Learning (AutoML) platforms from Amazon, Google and Microsoft, and found that they failed on this task without appropriately engineered features. Furthermore, we introduced a method that utilizes linear regression on Fourier series basis vectors, and demonstrated its effectiveness. Finally, we evaluated Large Language Models (LLMs) such as GPT-4, GPT-J, LLaMA and Falcon, and demonstrated their failures. In conclusion, feature engineering remains an important task to improve performance and increase interpretability of machine-learning models, even in the era of AutoML and LLMs.

description: Com’è noto, agli inizi degli anni ’50 del secolo scorso la città di Roma
cominciava la sua rapida e disordinata espansione verso il suburbio, divorando ettari di un territorio straordinariamente ricco di testimonianze storiche e archeologiche; queste, nei casi più fortunati, rimanevano, pur conservate nelle loro strutture monumentali, del tutto decontestualizzate, quali relitti ai margini del nuovo edificato (Figg. 1 e 2). Proprio in quegli anni, nell’ambito del dibattito intorno all’elaborazione del Nuovo Piano Regolatore Generale di Roma, destinato per la prima volta ad includere l’intero Agro Romano, con la distinzione fra zone di espansione urbanistica e zone non edificabili, cominciava a prendere forma l’istanza di  conservazione ambientale e paesistica di ampie zone del suburbio romano. Si profilava così la possibilità di affidare la salvaguardia del territorio, oltre che ad interventi di natura vincolistica ai sensi della legislazione vigente in materia di tutela storico-artistica e paesaggistica1, anche e soprattutto ad un’oculata pianificazione urbanistica, che mirasse alla conservazione non solo del “monumento”, ma anche del contesto territoriale di appartenenza.

description: Le informazioni geografiche costituiscono una componente essenziale per la modellizzazione e l’analisi delle trasformazioni del territorio. Il territorio è, infatti, una realtà dinamica interessata da continue modificazioni: l’evoluzione dei processi naturali e delle attività umane necessita, dunque, di strumenti in grado di rappresentare e controllare nel tempo i cambiamenti e l’assetto. La visione integrata di elementi informativi e cartografici, che le nuove tecnologie supportano, assolve all’esigenza di controllare l’efficacia delle scelte di  pianificazione effettuate. D’altronde, questa esigenza di verificare, di poter “vedere tutto” non è nuova. Nella Galleria delle Carte Geografiche in Vaticano, ad esempio, le carte che vi sono affrescate sembrano mettere materialmente il mondo sotto gli occhi; sia la parte tangibile, la Terra, sia la parte astratta,
ovvero i significati che l’uomo assegna al mondo per definirlo, progettarlo e organizzarlo secondo determinati simboli.

description: Direct optimal control theory for quantum dynamical problems presents itself as an interesting alternative to the traditional indirect optimal control. The method relies on the first discretize and then optimize paradigm, where a discretization of the dynamical equations leads to a nonlinear optimization problem. It has been applied successfully to the control of a bistable system where the wavepacket had been approximated by a parameterized Gaussian, leading to a semiclassical set of equations of motion (A. R. Ramos Ramos, O. Kühn, Front. Phys. 9 (2021) 615168). Motivated by these results, in the present paper we extend the application of the method to the case of exact wavepacket propagation using the example of a generic Fermi-resonance model. In particular we address the question how population of the involved overtone state can be avoided such as to reduce the effect of intramolecular vibrational energy redistribution. A methodological advantage is that direct optimal control theory offers flexibility when choosing the running cost, since there is no need to compute functional derivatives and coupling terms as in the case of indirect optimal control. We exploit this fact to include state populations in the running cost, which allows their optimization.

description: We study the concepts of complete positivity, positivity and non-Markovianity in a two-level open quantum system whose dynamics are governed by a time-local quantum master equation. We establish necessary and sufficient conditions on the time-dependent relaxation rates to ensure complete positivity and positivity of the dynamical map. We discuss their relations with the non-Markovian behavior of the open system. We also analyze the long-time asymptotic behavior of the dynamics as a function of the rates. We show under which conditions on the rates the system tends to the equilibrium state. Different examples illustrate this general study.

description: La partecipazione della Casanatense alla mostra "Meridiani e longitudini
a Roma", allestita nel Salone monumentale dal 4 al 19 marzo 2005 in occasione della XV Settimana della cultura scientifica e tecnologica, ha consentito ancora una volta di far convergere l’attenzione di studiosi e scienziati sul prezioso e ricco corpus di opere riguardanti l’astronomia che si conserva in questa prestigiosa biblioteca romana.
Già nel 1985 con Bibliotheca magica e nel 1991 con gli Arcani delle stelle, riscuotendo peraltro molti consensi dai cultori della materia, era stata data una interessante prospettiva di questo particolare settore del patrimonio casanatense. In quelle occasioni era stata anche presentata una serie di strumenti scientifici, alcuni dei quali acquistati dal prefetto Domenicano p. Giovan Battista Audiffredi (1714-1794), sotto la cui guida la Casanatense raggiunse nel ‘700 l’acme del suo splendore. La collaborazione tra istituzioni così diverse come da un lato la Casanatense – istituto bibliotecario di alta cultura che affonda le proprie radici nel secolo dei lumi e che attualmente è un organismo dipendente dal Ministero per i beni e le attività culturali – e dall’altro lo Studium Urbis – centro culturale nato nel 2000 per iniziativa del prof. Allan Ceen e vocato alla storia dell’architettura ed al disegno urbano in Italia - ha portato al risultato esaltante della  mostra Meridiani e longitudini a Roma di cui ora si pubblica il catalogo. Infatti il percorso espositivo casanatense del 2005 è stato la naturale prosecuzione di una ricerca iniziata dallo Studium Urbis nel 2002 con la mostra Meridiano. Italy’s prime meridian, in cui veniva ricostruita la storia del Meridiano di Monte Mario e presentata la collezione di carte geografiche di proprietà dello Studium stesso. Questa interessante collezione cartografica si è perfettamente amalgamata ai preziosi testi a stampa e documenti iconografici conservati nella Casanatense, consentendo di illustrare in modo suggestivo e al tempo stesso puntuale
il complesso tema proposto dalla mostra.

description: The Sustainable Oxymoron of Qualitative GIS
This paper discusses the idea of a qualitative GIS, by presenting an experiment held in Palermo during the last few years. It first presents a theoretical framework on the shifting paradigms concerning maps and GIS, and then introduces the current debate on mixing qualitative and quantitative data and techniques of analysis in GIScience. By collecting mental maps representing the neighbourhoods of Palermo and inserting them within a traditional GIS structure, the author has warped these traditional representations in order to obtain a map which is less technically accurate, yet more complying with the perception of the citizens. These operations have significant repercussions on the planning policies and the consideration of the role of geographers within the political agorà.

L’oxymore durable des SIG qualitatives
Cet article examine l’idée d’un SIG qualitatif, en présentant une expérience tenue à Palerme au cours des dernières années. Il présente d’abord un cadre théorique sur les paradigmes concernant les cartes et SIG, puis introduit le débat en cours sur le mélange des données et des techniques d’analyse qualitative et quantitative en cartographie. En recueillant des cartes mentales représentant les quartiers de Palerme
et en les insérant dans une structure SIG traditionnelle, l’auteur a déformé ces représentations traditionnelles afin d’obtenir une carte qui est techniquement moins précise, mais qui répond à la perception des citoyens. Ces opérations ont des répercussions importantes sur les politiques de planification et la prise en compte du rôle des géographes au sein de l’agorà politique.

Multimedialità e geografia. Le opportunità offerte dagli interactive documentary (i-doc)

description: Multimedia and geography. The possibilities of interactive documentaries (i-docs)
The paper reflects on the relationship between interactive documentaries (i-docs) and geographical education. Being in-between scientific research, work of art and journalistic inquiry, i-docs have registered an increasing diffusion in these last years as a tool both to report and narrate reality and as a source of information and documentation. Nevertheless, the scientific debate on interactive documentaries and on their potential applications in the educational field (and, more specifically, in the field of geographical education) are limited or almost absent. After an introduction where the theoretical foundations behind i-docs are discussed, the paper proposes
a geographical taxonomy of i-docs, based on the experience of space proposed by different typologies of documentaries. Thus, the paper focuses on the educational perspectives of i-docs, arguing that they incorporate an intrinsic spatio-temporal logic founded on contingency, multiplicity, and openness.

Le multimédia et l’éducation géographique. Les opportunités liées aux documentaires interactifs (i-docs)
Cet article présente une réflexion sur la relation entre les documentaires interactifs (i-docs) et l’éducation géographique. Les i-docs se posent au carrefour entre la recherche scientifique, l’expression artistique et l’enquête journalistique et ils ont enregistré une croissante diffusion dans les derniers temps comme outil pour raconter la réalité ainsi que comme source d’information et de documentation. Cependant, le débat scientifique sur ces dispositifs et sur leur possibles applications dans le domaine de l’éducation (et en particulier de l’éducation géographique) est encore très limité. Après une introduction dans laquelle s’exposent les fondations théoriques à la base de ces outils, l’article propose une taxonomie géographique des i-docs, à partir de l’expérience de l’espace géographique présentée par des différentes typologies de documentaire. Ensuite, le paper se focalise sur les perspectives éducationnelles liées à
l’utilisation des i-docs et il soutient qu’ils incorporent une propre logique spatiotemporelle fondée sur la contingence, sur la multiplicité et sur l’ouverture.

description: The nature of Type Ia supernova progenitors is still unclear. The outstanding characteristic of the single-degenerate scenario is that it contains hydrogen in the binary companion of the exploding white dwarf star, which, if mixed into the ejecta of the supernova in large amounts may lead to conflicts with the observations thus ruling out the scenario. We investigate the effect of the impact of Type Ia supernova ejecta on a main sequence companion star of the progenitor system. With a series of simulations we investigate how different parameters of this system affect the amount of hydrogen stripped from the companion by the impact. The stellar evolution code GARSTEC is used to set up the structure of the companion stars mimicking the effect of a binary evolution phase. The impact itself is simulated with the smoothed particle hydrodynamics code GADGET2. We reproduce and confirm the results of earlier grid-based hydrodynamical simulation. Parameter studies of the progenitor system are extended to include the results of recent binary evolution studies. The more compact structure of the companion star found here significantly reduces the stripped hydrogen mass. The low hydrogen masses resulting from a more realistic companion structure are consistent with current observational constraints. Therefore, the single-degenerate scenario remains a valid possibility for Type Ia supernova progenitors. These new results are not a numerical effect, but the outcome of different initial conditions.

description: Genus Gadomus Regan, 1903
DISTINGUISHING FEATURES.— Chin barbel present, usually thick and long. V rays usually 8, rarely 9. Second spinous ray of 1D, upper ray of P, and outermost ray of V usually elongated, in some species extremely long; outer V ray usually rather thick.
REMARKS.— The genus was revised by Howes and Crimmen (1990), who based their work mostly on the literature and old, previously recorded specimens (none recently collected). With respect to Gadomus aoteanus, they followed McCann and McKnight (1980), who gave an erroneous count of V 9, but examination of the holotype and many other specimens (by TI) of that species showed that there are consistently eight rays in each fin. Gilbert (1905:658) gave a count of V 9 for the holotype (and only type specimen) of G. melanopterus; this is the only record of nine rays in a specimen of Gadomus that we are aware of. A second non-type specimen (CAS-SU 8545) that he reported in the original description has V 8.
Seven of the 12 described species of Gadomus are found in the western Pacific, but there may be others that are new to science. The species from the Indo-Pacific region have, for the most part, been inadequately circumscribed owing to the lack of large series from many localities. A thorough review of the genus using more recently collected material and genetic analyses is badly needed.

description: Giorgio Mangani è un geografo dalla collocazione difficile. Di quelli che
suscitano riflessioni sulla natura della geografia, su quanto essa sia scienza compiuta e autonoma oppure forma ibrida insofferente a ogni griglia di ripartizione del sapere e fisiologicamente incapace di darsi una sistematizzazione soddisfacente. Con il rischio permanente, per chi contempla la seconda opzione, di sfumare indistintamente verso altri settori scientifici. Infatti, oltre che un geografo, Mangani potrebbe a buon diritto essere considerato uno storico, della cartografia o dell’arte o del costume o, come direbbero in Francia, delle mentalità. Tale è la sua facilità di attraversare i campi disciplinari. I libri in recensione possono quindi essere letti da varie prospettive. Io ho usato quella del geografo politico; così, ad esempio, il ruolo del mito nella costruzione della nazione mi ha interessato in relazione alla “territorializzazione della memoria”, per usare un’espressione di Anthony Smith di cui Mangani è un seguace.

description: Biomass derived from the plant waste in the environment has been recognized as a potential source for preparing adsorbent in recent years. In this context, abandoned bamboo leaves from the surrounding area were collected and used as carbon precursor to prepare novel adsorbent for ammonia nitrogen removal. Bamboo leaves were treated with alkaline solution to produce biomass fiber (BF), then BF was reacted with aluminum nitrate nonahydrate and copper(ii) nitrate hydrate to form a Cu-Al composite oxide layer on the surface. Samples were well characterized by SEM, XRD and BET technique. The influencing factors including the pH, temperature, the time, and the dosage of adsorbent on the adsorption of ammonia nitrogen were studied. It was found that the maximum adsorption capacity toward ammonia nitrogen was fitted out to be 18.29 mg/g from the Langmuir isotherms model. In addition, the adsorbent showed outstanding total ammonia nitrogen removal in actual domestic sewage (Total ammonia nitrogen, TN, 12.6 ∼ 16.2 mg/L), which is significantly higher than that of the commercial activated carbon. Kinetics and thermodynamics studies indicated that the synergistic adsorption effect between biomass material and metal oxide plays a dominate role in the adsorption process. Therefore, the proposed strategy provides a promising way to deal with ammonia nitrogen wastewater and other types of water pollution. Besides, the reuse of surrounding plant waste is also consistent with the concept of green chemistry.

description: The observation and description of collective excitations in solids is a fundamental issue when seeking to understand the physics of a many-body system. Analysis of these excitations is usually carried out by measuring the dynamical structure factor, S(Q, $ω$), with inelastic neutron or x-ray scattering techniques and comparing this against a calculated dynamical model. Here, we develop an artificial intelligence framework which combines a neural network trained to mimic simulated data from a model Hamiltonian with automatic differentiation to recover unknown parameters from experimental data. We benchmark this approach on a Linear Spin Wave Theory (LSWT) simulator and advanced inelastic neutron scattering data from the square-lattice spin-1 antiferromagnet La$_2$NiO$_4$. We find that the model predicts the unknown parameters with excellent agreement relative to analytical fitting. In doing so, we illustrate the ability to build and train a differentiable model only once, which then can be applied in real-time to multi-dimensional scattering data, without the need for human-guided peak finding and fitting algorithms. This prototypical approach promises a new technology for this field to automatically detect and refine more advanced models for ordered quantum systems.

It is found that there exists three classes of such $r$-matrices, one of them being a novel two-parametric one. The (A)dS and Minkowskian Poisson homogeneous spaces corresponding to these three deformations are explicitly constructed in both local and ambient coordinates. Their quantization is performed, thus giving rise to the associated noncommutative spacetimes, that in the Minkowski case are naturally expressed in terms of quantum null-plane coordinates, and they are always defined by homogeneous quadratic algebras. Finally, non-relativistic and ultra-relativistic limits giving rise to novel Newtonian and Carrollian noncommutative spacetimes are also presented.

description: Visual target navigation in unknown environments is a crucial problem in robotics. Despite extensive investigation of classical and learning-based approaches in the past, robots lack common-sense knowledge about household objects and layouts. Prior state-of-the-art approaches to this task rely on learning the priors during the training and typically require significant expensive resources and time for learning. To address this, we propose a new framework for visual target navigation that leverages Large Language Models (LLM) to impart common sense for object searching. Specifically, we introduce two paradigms: (i) zero-shot and (ii) feed-forward approaches that use language to find the relevant frontier from the semantic map as a long-term goal and explore the environment efficiently. Our analysis demonstrates the notable zero-shot generalization and transfer capabilities from the use of language. Experiments on Gibson and Habitat-Matterport 3D (HM3D) demonstrate that the proposed framework significantly outperforms existing map-based methods in terms of success rate and generalization. Ablation analysis also indicates that the common-sense knowledge from the language model leads to more efficient semantic exploration. Finally, we provide a real robot experiment to verify the applicability of our framework in real-world scenarios.

description: By using coupling and Girsanov transformations, the dimension-free Harnack inequality and the strong Feller property are proved for transition semigroups of solutions to a class of stochastic generalized porous media equations. As applications, explicit upper bounds of the $L^p$-norm of the density as well as hypercontractivity, ultracontractivity and compactness of the corresponding semigroup are derived.

An expert view creation system for database design
Creators: name: Storey, Veda Catherine
Publisher: name: University of British Columbia
Year: 2010

description: The process of generating user views during logical database design is formalized and expressed as a set of rules which comprise the knowledge base of an expert system. This system, called the View Creation System, engages the user in a dialogue to determine information requirements. These requirements are then translated into a set of Fourth Normal Form relations representing a view. The data model on which the system is based is the Entity-Relationship Model. Using this model, the system elicits entities, attributes and relationships while trying to detect and rectify inconsistencies and ambiguities in the user's input. With the aid of the user, functional dependencies are isolated and resolved before the final set of relations is produced.

description: This work focuses on the problem of visual target navigation, which is very important for autonomous robots as it is closely related to high-level tasks. To find a special object in unknown environments, classical and learning-based approaches are fundamental components of navigation that have been investigated thoroughly in the past. However, due to the difficulty in the representation of complicated scenes and the learning of the navigation policy, previous methods are still not adequate, especially for large unknown scenes. Hence, we propose a novel framework for visual target navigation using the frontier semantic policy. In this proposed framework, the semantic map and the frontier map are built from the current observation of the environment. Using the features of the maps and object category, deep reinforcement learning enables to learn a frontier semantic policy which can be used to select a frontier cell as a long-term goal to explore the environment efficiently. Experiments on Gibson and Habitat-Matterport 3D (HM3D) demonstrate that the proposed framework significantly outperforms existing map-based methods in terms of success rate and efficiency. Ablation analysis also indicates that the proposed approach learns a more efficient exploration policy based on the frontiers. A demonstration is provided to verify the applicability of applying our model to real-world transfer.

description: Billions of photos are uploaded to the web daily through various types of social networks. Some of these images receive millions of views and become popular, whereas others remain completely unnoticed. This raises the problem of predicting image popularity on social media. The popularity of an image can be affected by several factors, such as visual content, aesthetic quality, user, post metadata, and time. Thus, considering all these factors is essential for accurately predicting image popularity. In addition, the efficiency of the predictive model also plays a crucial role. In this study, motivated by multimodal learning, which uses information from various modalities, and the current success of convolutional neural networks (CNNs) in various fields, we propose a deep learning model, called visual-social convolutional neural network (VSCNN), which predicts the popularity of a posted image by incorporating various types of visual and social features into a unified network model. VSCNN first learns to extract high-level representations from the input visual and social features by utilizing two individual CNNs. The outputs of these two networks are then fused into a joint network to estimate the popularity score in the output layer. We assess the performance of the proposed method by conducting extensive experiments on a dataset of approximately 432K images posted on Flickr. The simulation results demonstrate that the proposed VSCNN model significantly outperforms state-of-the-art models, with a relative improvement of greater than 2.33%, 7.59%, and 14.16% in terms of Spearman's Rho, mean absolute error, and mean squared error, respectively.

Gadomus multifilis (Günther, 1887): Shao et al., 2008: table 2 (4 spec., SWT, first record for Taiwan).
MATERIAL EXAMINED (9 spec.).— SWT: ASIZP 64092 (4, 30–50.6 HL, 130+-260+ TL); CD 193, 821 m. SCS: ASIZP 66334 (1, 38 HL, 240 TL) and ASIZP 66240 (1, 37.1 HL, 223+ TL), CD 307, 1591 m; ASIZP 66189 (1, 35.1 HL, 170+ TL) and ASIZP 66810 (1, 35.5 HL, 185+ TL); CD 322, 1098 m. Other specimens: ASIZP 68056 (1, 34.7 HL, 223 TL); CC2702 Aurora, 944–1004 m, 27 May 2007.
DISTINGUISHING FEATURES.— A species of Gadomus with chin barbel about 50–75% of HL; length elongated P ray 2–3 times HL, prolonged ray in 1D and V much greater than HL; 1D II,8–9, P i16–i19; V 8; outer gill rakers sharply tipped, lathlike (6–7) + (23–26); pyl. caeca 24–29. Interorbital width 16–17% HL, orbit diameter 21–24%; suborbital depth 10–15%; upper jaw length 55–60%; chin barbel 29–72% (compiled from Gilbert and Hubbs, 1920).
DISTRIBUTION.— Taiwan (SWT, SCS) and broadly across Indo-West Pacific, if these specimens are the same as G. multifilis.
REMARKS.— Our identification of nine Taiwan specimens has been problematical, although they for the most part fit the original description and subsequent descriptions of G. multifilis by Gilbert and Hubbs (1920) and Howes and Crimmen (1990). However, four of the ASIZ specimens (ASIZP 64092) have a slightly lower count of GR-I (6 + 23) and more pyloric caeca (30–47 in 4 spec.); ASIZP 66334 had more rakers, 7 + 26 rakers. Gilbert and Hubbs (1920:406–408) gave the gill-raker count as 6 + (26–27) and pyloric caeca as 12 and 16. Howes and Crimmen (1990:195–197) counted 6 + 25 gill-rakers for the holotype and eight other specimens, and counts of 25 and 15 pyloric caeca in two of those specimens. The low gill-raker counts and high pyloric caeca counts of ASIZP 64092 agree rather well with those Gilbert and Hubbs (1920:403) gave for G. introniger (gill-rakers (5–6) + (20–24) and “pyloric caeca [in several specimens, 35 to 52”]). However, the orbit diameter and interorbital width are less in our specimens and the gill-rakers are pointed, not bluntly tipped, as in G. introniger. Similarly, the counts of gill-rakers and pyloric caeca, plus the interorbital and orbit dimensions, agree closely with G. magnifilis, but the gill-rakers are also bluntly tipped in that species. We see no resolution to our dilemma without a thorough revision of the genus using extensive material from throughout the Indo-West Pacific, and especially from that critical region around the Philippine Islands and the Malay Archipelago.

description: The mass scale of fundamental strings can be as low as few TeV/c^2 provided that spacetime extends into large extra dimensions. We discuss the phenomenological aspects of weakly coupled low mass string theory related to experimental searches for physics beyond the Standard Model at the Large Hadron Collider (LHC). We consider the extensions of the Standard Model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes. We focus on the model-independent, universal features of low mass string theory. We compute, collect and tabulate the full-fledged string amplitudes describing all 2->2 parton scattering subprocesses at the leading order of string perturbation theory. We cast our results in a form suitable for the implementation of stringy partonic cross sections in the LHC data analysis. The amplitudes involving four gluons as well as those with two gluons plus two quarks do not depend on the compactification details and are completely model-independent. They exhibit resonant behavior at the parton center of mass energies equal to the masses of Regge resonances. The existence of these resonances is the primary signal of string physics and should be easy to detect. On the other hand, the four-fermion processes like quark-antiquark scattering include also the exchanges of heavy Kaluza-Klein and winding states, whose details depend on the form of internal geometry. They could be used as ``precision tests'' in order to distinguish between various compactification scenarios.
