Baugruppen. Innovation through collaborative infrastructures
Creators: name: De Jorge-Huertas, Virginia
Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2019

description: In the 1990s in Berlin the Baugruppen movement developed an innovative housing project as a “typological” experimentation. Several case studies will be analysed based on the users’ needs, the self-made construction, affordable options, collaborative housing, and creative participation. Once this model has been known a potential alternative can be applied to the shortage of housing options in Europe. This paper analyses several case-studies realized in Berlin which could be defined as a compact “vertical village” or “vertical mat-building” by land consumption reduction. Adopting the theoretical approach of the Baugruppen, the case studies will be evaluated through five key points: common infrastructure, personalized spheres, variable volume, hanging gardens, and shared common spaces, to validate their “typological” experimental quality.

description: In this short note we observe, on locally symmetric spaces of higher rank, a connection between the growth indicator function introduced by Quint and the modified critical exponent of the Poincaré series equipped with the polyhedral distance. As a consequence, we provide a different characterization of the bottom of the $L^2$-spectrum of the Laplace-Beltrami operator in terms of the growth indicator function. Moreover, we explore the relationship between these three objects and the temperedness.

description: Instability of silk fibroin nanoparticles (SFNPs) in physiologic condition hinders its application as drug delivery vehicle. Herein, indocyanine green (ICG) loaded silk fibroin nanoparticles (ICG-SFNPs) was firstly prepared and then crosslinked by proanthocyanidins to obtain the stable ICG-CSFNPs for killing the residual tumour niche under near infra-red irradiation (NIR) after surgery. The particle size and zeta potentials of ICG-CSFNPs was 120.1 nm and -40.4 mV, respectively. Moreover, ICG-CSFNPs exhibited good stability of particle size in the physiological medium. Meanwhile, the stable photothermal properties of ICG-CSFNPs were not compromised even after several cycles of NIR. Few of the ICG-CSFNPs were phagocytized by RAW264.7 macrophage in vitro, while they were easily internalized by C6 glioma cells, resulting in their significant toxicity on tumour cells after NIR. The pharmacokinetic study showed that ICG-CSFNPs had a longer blood circulation time than ICG-SFNPs, making them more distribution in glioma after intravenous administration in vivo. Meanwhile, the pharmacological study showed the more effective inhibition of tumour growth was exhibited by ICG-CSFNPs in C6 glioma-bearing mice after NIR. Overall, the cross-linked nanoparticles of silk fibroin may be a promising vehicle of ICG for photothermal therapy of glioma after surgical resection.
Non-Acceleration of Sgr A*: Implications for Galactic Structure
Creators: name: Gould, Andrew

Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We show that observations by Backer and collaborators over the past two decades constrain the time derivative of the proper motion of Sgr A* to be less than 0.14 mas yr^{-2}. Using this result and a preliminary measurement by Eckart and Genzel of sigma ~500 kms for the velocity dispersion of the star cluster within 0.2" of Sgr A*, we derive the following implications. First, if the nuclear star cluster is dominated by a massive black hole, then either Sgr A* is that black hole or it orbits the black hole with a radius less than 3 AU. Second, even if the star cluster does not contain a massive black hole, Sgr A* is constrained to move slower than 20 kms (1 sigma) relative to the center of mass of the cluster. The Galactocentric distance is therefore R_0=7.5 +/- 0.7 kpc, independent of the nature of Sgr A*. These error bars could be substantially reduced by future observations. If they are, it will also be possible to probe the motion of the nuclear star cluster relative to the center of mass of the Galaxy at the ~4 kms level.

description: The thermoelectric performance at a given output power of a voltage-probe heat engine, exposed to an external magnetic field, is investigated in linear irreversible thermodynamics. For the model, asymmetric parameter, general figures of merit and efficiency at a given output power are analytically derived. Results show a trade-off between efficiency and output power, and we recognize optimum-efficiency values at a given output power are enhanced compared to a Büttiker-probe heat engine due to the presence of a characteristic parameter, namely $d_m$. Moreover, similar to a Büttiker-probe heat engine, the universal bounds on the efficiency are obtained, and the efficiency at a given output power can exceed the Curzon-Ahlborn limit. These findings have practical implications for the optimization of realistic heat engines and refrigerators. By controlling the values of the asymmetric parameter, the figures of merit, and $d_m$, it may be possible to design more efficient and powerful thermoelectric devices.

description: Schrödinger's equation serves as a fundamental component in characterizing quantum systems, wherein both quantum state tomography and Hamiltonian learning are instrumental in comprehending and interpreting quantum systems. While numerous techniques exist for carrying out state tomography and learning Hamiltonians individually, no method has been developed to combine these two aspects. In this study, we introduce a new approach that employs the attention mechanism in transformer models to effectively merge quantum state tomography and Hamiltonian learning. By carefully choosing and preparing the training data, our method integrates both tasks without altering the model's architecture, allowing the model to effectively learn the intricate relationships between quantum states and Hamiltonian. We also demonstrate the effectiveness of our approach across various quantum systems, ranging from simple 2-qubit cases to more involved 2D antiferromagnetic Heisenberg structures. The data collection process is streamlined, as it only necessitates a one-way generation process beginning with state tomography. Furthermore, the scalability and few-shot learning capabilities of our method could potentially minimize the resources required for characterizing and optimizing quantum systems. Our research provides valuable insights into the relationship between Hamiltonian structure and quantum system behavior, fostering opportunities for additional studies on quantum systems and the advancement of quantum computation and associated technologies.

description: We study properties of the mean curvature one-form and its holomorphic and antiholomorphic cousins on a transverse Kähler foliation. If the mean curvature of the foliation is automorphic, then there are some restrictions on basic cohomology similar to that on Kähler manifolds, such as the requirement that the odd basic Betti numbers must be even. However, the full Hodge diamond structure does not apply to basic Dolbeault cohomology unless the foliation is taut.

State Feminism: The Lived Experiences of Qatari Women Leaders Within Qatar Foundation
Creators: name: Al Dosari, Abeer Abdul Rahman
Publisher: name: Manara - Qatar Research Repository
Year: 2025
Subjects: classificationCode: 44
subject: Human society

description: This study focuses on how the lived experiences of Qatari women within the Qatar state feminism policies are delivered by Qatar Foundation. The emphasis on women is informed by the challenges they face in traversing various juridical, social, political and economic spheres, including who initiates and implements governmental actions to create and reinforce women’s status in Qatari society; for what reason; women’s part and contribution in state feminism strategy processes; the statutory, executive and managerial depiction of women within society; and their connection to existing feminist institutions or programmes. The study focused on a life history analysis of eight (8) elite Qatari women who worked for Qatar Foundation. The results showed reflected that both public and private patriarchy impact on the objectives of state feminism as described in the lives of the women. Secondly, women adopted three main strategies; deferring, exit and conformity strategies to respond to private patriarchy and hence apply themselves to the public spheres. Finally, two main policy aspects noted in the study were that; there was a need to review the personal status laws and family laws and the wide pay gap between men needed addressing while ensuring women took a lead role in initiating some or all these policies.

description: Correlative microscopy is a powerful technique that combines the advantages of multiple imaging modalities to achieve a comprehensive understanding of investigated samples. For example, fluorescence microscopy provides unique functional contrast by imaging only specifically labeled components, especially in biological samples. However, the achievable structural information on the sample in its full complexity is limited. Here, the intrinsic label-free carbon contrast of water window soft X-ray microscopy can complement fluorescence images in a correlative approach ultimately combining nanoscale structural resolution with functional contrast. However, soft X-ray microscopes are complex and elaborate, and typically require a large-scale synchrotron radiation source due to the demanding photon flux requirements. Yet, with modern high-power lasers it has become possible to generate sufficient photon flux from laser-produced plasmas, thus enabling laboratory-based setups. Here, we present a compact table-top soft X-ray microscope with an integrated epifluorescence modality for 'in-situ' correlative imaging. Samples remain in place when switching between modalities, ensuring identical measurement conditions and avoiding sample alteration or destruction. We demonstrate our new method by multimodal images of several exemplary samples ranging from nanoparticles to various multicolor labeled cell types. A structural resolution of down to 50 nm was reached.

Year: 2019

description: The paper deals with the dichotomy between the horizontal and vertical development of the built environment in urban contexts while taking into consideration different densities and settlement logics by following the specific approach of environmental and technological design. The research focuses on two well-known environmental parameters, wind and sun, identifying specific performance indicators related to natural ventilation (pressure coefficient and wind speed profile) and envelope-related energy needs (percentage of openings, shape and orientation of a spatial unit). For each indicator, a sensitivity analysis was carried out taking into consideration density and building height variations to evaluate the design choices from early-design phases.

description: Repeated projective measurements in unitary circuits can lead to an entanglement phase transition as the measurement rate is tuned. In this work, we consider a different setting in which the projective measurements are replaced by dynamically chosen unitary gates that minimize the entanglement. This can be seen as a one-dimensional unitary circuit game in which two players get to place unitary gates on randomly assigned bonds at different rates: The "entangler" applies a random local unitary gate with the aim of generating extensive (volume law) entanglement. The "disentangler," based on limited knowledge about the state, chooses a unitary gate to reduce the entanglement entropy on the assigned bond with the goal of limiting to only finite (area law) entanglement. In order to elucidate the resulting entanglement dynamics, we consider three different scenarios: (i) a classical discrete height model, (ii) a Clifford circuit, and (iii) a general $U(4)$ unitary circuit. We find that both the classical and Clifford circuit models exhibit phase transitions as a function of the rate that the disentangler places a gate, which have similar properties that can be understood through a connection to the stochastic Fredkin chain. In contrast, the "entangler" always wins when using Haar random unitary gates and we observe extensive, volume law entanglement for all non-zero rates of entangling.

description: Interpreting some dimensions of the horizontal/vertical relationship in the transformation cycle of Milan, this article develops a reflection on the current urban planning phase of this city referring to some of its specific characteristics. Despite the emphasis on the common debate as well as the scientific one, considering the vertical development of Milan, this paper argues that the increasing quality of the city, as perceived in recent years, derives from its improved ‘horizontality.’ This article, also resorting to sources from the local debate, argues this thesis in a discussion on peculiar features of some of the most recent, and the near future, transformations of the city, including those of the former trade fair site (City Life project), Garibaldi-Repubblica area (Porta Nuova project), and the abandoned railway yards.

description: The $K\toππ$ system is analyzed in the chiral limit within the Standard Model. We discuss how to connect the short-distance running in the $|ΔS|=1$ case to the matrix-elements calculated in a low-energy approximation in a scheme-independent fashion. We calculate this correction and the resulting Wilson Coefficients. The matrix elements are calculated to next-to-leading order in the $1/N_c$ expansion and combined with the Wilson coefficients to calculate the two isospin amplitudes and $ε_K^\prime$. The $ΔI=1/2$ rule is reproduced within expected errors and we obtain a substantially larger value for $ε_K^\prime/ε_K$ than most other analysises. We discuss the reasons for this difference. We also suggest that the $X$-boson method is an option for lattice QCD calculations.

description: Radio Access Networks (RANs) for telecommunications represent large agglomerations of interconnected hardware consisting of hundreds of thousands of transmitting devices (cells). Such networks undergo frequent and often heterogeneous changes caused by network operators, who are seeking to tune their system parameters for optimal performance. The effects of such changes are challenging to predict and will become even more so with the adoption of 5G/6G networks. Therefore, RAN monitoring is vital for network operators. We propose a self-supervised learning framework that leverages self-attention and self-distillation for this task. It works by detecting changes in Performance Measurement data, a collection of time-varying metrics which reflect a set of diverse measurements of the network performance at the cell level. Experimental results show that our approach outperforms the state of the art by 4% on a real-world based dataset consisting of about hundred thousands timeseries. It also has the merits of being scalable and generalizable. This allows it to provide deep insight into the specifics of mode of operation changes while relying minimally on expert knowledge.

Year: 2023
Subjects: subject: Methodology (stat.ME)

description: Most multivariate outlier detection procedures ignore the spatial dependency of observations, which is present in many real data sets from various application areas. This paper introduces a new outlier detection method that accounts for a (continuously) varying covariance structure, depending on the spatial neighborhood of the observations. The underlying estimator thus constitutes a compromise between a unified global covariance estimation, and local covariances estimated for individual neighborhoods. Theoretical properties of the estimator are presented, in particular related to robustness properties, and an efficient algorithm for its computation is introduced. The performance of the method is evaluated and compared based on simulated data and for a data set recorded from Austrian weather stations.
Dynamical density response and optical conductivity in topological metals

description: Topological metals continue to attract attention as novel gapless states of matter. While there by now exists an exhaustive classification of possible topologically nontrivial metallic states, their observable properties, that follow from the electronic structure topology, are less well understood. Here we present a study of the electromagnetic response of three-dimensional topological metals with Weyl or Dirac nodes in the spectrum, which systematizes and extends earlier pioneering studies. In particular, we argue that a smoking-gun feature of the chiral anomaly in topological metals is the existence of propagating chiral density modes even in the regime of weak magnetic fields. We also demonstrate that the optical conductivity of such metals exhibits an extra peak, which exists on top of the standard metallic Drude peak. The spectral weight of this peak is transferred from high frequencies and its width is proportional to the chiral charge relaxation rate.

description: The statics of the Fredrickson-Andersen model (FAM) of the liquid-glass transition is solved on the Bethe lattice (BL). The kinetic constraints of the FAM imply on the BL an ergodicity-breaking transition to a (glassy) phase where a fraction of spins of the system is permanently blocked, and the remaining "free" spins become non-trivially correlated. We compute several observables of the ergodicity-broken phase, such as the self-overlap, the configurational entropy and the spin-glass susceptibility, and we compare the analytical predictions with numerical experiments. The cavity equations that we obtain allow to define algorithms for fast equilibration and accelerated dynamics. We find that at variance with spin-glass models, the correlations inside a state do not exhibit a critical behavior.

Augmented Reality (AR) in vocational education: A Study on two principles of the Cognitive Theory of Multimedia Learning (CTML) in AR and their effects on students' cognitive load, learning performance, and motivation

description: This study investigates the applicability of two key principles from the cognitive theory of multimedia learning (CTML) — the modality principle and the redundancy principle — in augmented reality (AR). While these principles have been extensively studied in traditional multimedia settings, their effectiveness in immersive technologies, such as AR, remains largely unexplored. Using a between-subjects design with three instructional conditions (audio-only, text-only, and audio and text combined), this study examined how different instructional modalities in AR influence cognitive load, learning performance, and motivation. A total of 104 apprentices from various vocational fields participated in the experiment, which involved learning a T-shirt folding technique using Microsoft HoloLens 2 AR goggles. The results demonstrated that the expected advantages of audio over text (modality principle) and the disadvantages of redundant information (redundancy principle) were not observed in AR as they typically are in traditional multimedia environments, with no differences in intrinsic or extraneous cognitive load across the three conditions. However, the study found significant relationships between cognitive load and motivation; that is, higher perceived extraneous cognitive load was associated with lower perceived motivation levels, while higher perceived germane cognitive load correlated strongly with increased perceived motivation. Learning performance analysis suggested a trend favoring audio-based instruction (either alone or combined with text) over text-only instruction, although these differences did not reach statistical significance. The findings indicate that the established CTML principles may operate differently in AR learning environments, highlighting the need for further investigation of these principles in AR. Additionally, the strong relationship identified between cognitive load and motivation highlights the importance of considering motivational factors when designing AR-based learning experiences. These results have important implications for the design of AR-based instructional materials, particularly in vocational education settings where procedural knowledge acquisition is crucial.

description: Proximal soil sensors are taking hold in the understanding of soil hydrogeological processes involved in precision agriculture. In this context, permanently installed gamma ray spectroscopy stations represent one of the best space-time trade off methods at field scale. This study proved the feasibility and reliability of soil water content monitoring through a seven-month continuous acquisition of terrestrial gamma radiation in a tomato test field. By employing a 1 L sodium iodide detector placed at a height of 2.25 m, we investigated the gamma signal coming from an area having a ~25 m radius and from a depth of approximately 30 cm. Experimental values, inferred after a calibration measurement and corrected for the presence of biomass, were corroborated with gravimetric data acquired under different soil moisture conditions, giving an average absolute discrepancy of about 2%. A quantitative comparison was carried out with data simulated by AquaCrop, CRITeRIA, and IRRINET soil-crop system models. The different goodness of fit obtained in bare soil condition and during the vegetated period highlighted that CRITeRIA showed the best agreement with the experimental data over the entire data-taking period while, in presence of the tomato crop, IRRINET provided the best results.

description: We suggest a simple modification of the maximal mixing scenario (with $S_3$ permutation symmetry) for three light neutrinos. Our neutrino mass matrix has smaller permutation symmetry $S_{2}$ ($ν_μ \leftrightarrow ν_{e}$), and is consistent with all neutrino experiments except the $^{37}$Cl experiment. The resulting mass eigenvalues for three neutrinos are $m_{1} \approx (2.55-1.27) \times 10^{-3} eV, m_{2,3} \approx (0.71-1.43) eV$ for $Δm_{LSND}^{2} = 0.5 - 2.0 eV^2$. Then these light neutrinos can account for $\sim (2.4-4.8)% (6.2-12.4 %)$ of the dark matter for $h = 0.8 (0.5)$. Our model predicts the $ν_μ \rightarrow ν_τ$ oscillation probability in the range sensitive to the future experiments such as CHORUS and NOMAD.

description: The Young-Laplace's equation is established based on liquid membrane without shearing resistance. It is not valid for solid. By taking into account the in-plane shearing and transverse shearing within the surface layer, we reconstruct the Young-Laplace's equation so as to characterize the surface of solid. A new version of the Young-Laplace's equation is proposed. It shows that the surface equilibrium of solid is determined by the bulk stress, surface membrane stress and surface transverse stress together. The transverse shear stress depends on the gradient of the Gaussian curvature of surface and strain. The intrinsic membrane stress and surface transverse shear stress cause the residual stresses to appear in the interior of solid. The intrinsic surface transverse shear stress only occurs in the non-spherical body.

Understanding the effects produced by different building volumes is an important aspect and the solar access analysis represents the specific field of study. The study proposes a design methodology, developing a framework with criteria, aspects and example applications, with the aim to evaluate the energy effects related to the different volumetric configurations.

description: Electronic interferometers using the chiral, one-dimensional (1D) edge channels of the quantum Hall effect (QHE) can demonstrate a wealth of fundamental phenomena. The recent observation of phase jumps in a Fabry-Pérot (FP) interferometer revealed anyonic quasiparticle exchange statistics in the fractional QHE. When multiple integer edge channels are involved, FP interferometers have exhibited anomalous Aharonov-Bohm (AB) interference frequency doubling, suggesting putative pairing of electrons into 2e quasiparticles. Here, we use a highly tunable graphene-based QHE FP interferometer to observe the connection between interference phase jumps and AB frequency doubling, unveiling how strong repulsive interaction between edge channels leads to the apparent pairing phenomena. By tuning electron density in-situ from filling factor ν<2 to ν>7, we tune the interaction strength and observe periodic interference phase jumps leading to AB frequency doubling. Our observations demonstrate that the combination of repulsive interaction between the spin-split ν=2 edge channels and charge quantization is sufficient to explain the frequency doubling, through a near-perfect charge screening between the localized and extended edge channels. Our results show that interferometers are sensitive probes of microscopic interactions and enable future experiments studying correlated electrons in 1D channels using our highly tunable platform.

The contemporary project of the tall residential building, between density and intensity
Creators: name: Moscatelli, Matteo
Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2019

description: The essay investigates models and techniques of intervention for increasing the urban density, illustrating how the tall building can be a still useful device in the densification processes, and what circumstances it should face also in relationship with its evolution in the European architecture of the XX century. Several recent case-studies allow to highlight the role of the technology, addressed not only to overcome height limits, but also to actuate regenerative operations on existing tall buildings, and the necessity of associating, to the increase of density in the urban fabric, the development of an intensity of uses and relationships that can arise and intertwine in it.

description: To better understand the effects of strong coupling and QCD at high temperature in QGP, by using holographic model, we investigate the dissociation effect of bottomonium under the higher-order curvature corrections to the supergravity action corresponding to the corrections of large N expansion of boundary CFT in the side of field theory. The results show that effective potential is not a good physical quantity to estimate the dissociation strength of bottomonium in the case of finite wave number and considering the higher-order curvature corrections. Therefore, we calculate the quasinormal spectra(QNMs) and the differential configuration entropy(DCE). It is found that the dissociation effect is stronger for the stronger coupling.

Near-IR photometry of disk galaxies: search for nuclear isophotal twist and double bars

Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a near-IR, mainly H band, photometry of 72 nearby disk galaxies. The main goal of the survey was to search for isophotal twist inside their nuclear regions. As the twist can be due in some cases to projection effects, rather than resulting from a dynamical phenomenon, we deproject - under the simplifying assumption of a 2D geometry - all galaxies whose disk position angle and inclination are known, the latter not exceeding 75 degrees. We show the ellipticity, position angle and surface brightness radial profiles, and discuss how a projection of 2D and 3D bars can distort the isophotes, give an illusion of a non-existing double bar or mask a real one. We report 15 new double-barred galaxies and confirm 2 detected previously. We identify 14 additional twists not known before and we also find nuclear triaxial structures in three SA galaxies. The frequency of Seyferts among galaxies with nuclear bars or twists is high. As a secondary product, we publish structural parameters (length and axis ratio) of large-scale bars in order to extend still scarce data on bars in the near-IR.

Ehrenfest Paradox: A Careful Examination

description: The Ehrenfest paradox for a rotating ring is examined and a kinematic resolution, within the framework of the special theory of relativity, is presented. Two different ways by which a ring can be brought from rest to rotational motion, whether by keeping the rest lengths of the blocks constituting the ring constant or by keeping their lengths in the inertial frame constant, are explored and their effect on the length of the material ring in the inertial as well as the co-rotating frame is checked. It is found that the ring tears at a point in the former case and remains intact in the latter case, but in neither of the two cases is the motion of the ring Born rigid during the transition from rest to rotational motion.

Capturing long-range memory structures with tree-geometry process tensors

description: We introduce a class of quantum non-Markovian processes -- dubbed process trees -- that exhibit polynomially decaying temporal correlations and memory distributed across time scales. This class of processes is described by a tensor network with tree-like geometry whose component tensors are (1) causality-preserving maps (superprocesses) and (2) locality-preserving temporal change of scale transformations. We show that the long-range correlations in this class of processes tends to originate almost entirely from memory effects, and can accommodate genuinely quantum power-law correlations in time. Importantly, this class allows efficient computation of multi-time correlation functions. To showcase the potential utility of this model-agnostic class for numerical simulation of physical models, we show how it can efficiently approximate the strong memory dynamics of the paradigmatic spin-boson model, in terms of arbitrary multitime features. In contrast to an equivalently costly matrix product operator (MPO) representation, the ansatz produces a fiducial characterization of the relevant physics. Finally, leveraging 2D tensor network renormalization group methods, we detail an algorithm for deriving a process tree from an underlying Hamiltonian, via the Feynmann-Vernon influence functional. Our work lays the foundation for the development of more efficient numerical techniques in the field of strongly interacting open quantum systems, as well as the theoretical development of a temporal renormalization group scheme.

The chinese ‘high and slender’ condominium

Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2019

description: The vertical dimension in the urban structure of Chinese megacities is the unique key that has allowed to cluster millions of people in highly concentrated areas. The exponential growth of Chinese cities since the ‘80s of the last century has been possible thanks to social and land policies in support of urbanism developed through models of constructions that have favored the vertical dimension alone. The essay, after having retraced the history of vertical urbanization in the Chinese metropolis, puts a critical emphasis on the typology of the Chinese condominium.

Interplay of Hard and Soft Physics in Small $x$ Deep Inelastic Processes

description: Coherence phenomena, the increase with energy of coherence length and the non-universality of parton structure of the effective Pomeron are explained. New hard phenomena directly calculable in QCD such as diffractive electroproduction of states with $M^2\ll Q^2$ and the color transparency phenomenon as well as new options to measure the light-cone wave functions of various hadrons are considered. An analogue of Bjorken scaling is predicted for the diffractive electroproduction of $ρ$ mesons at large momentum transfers and for the production of large rapidity gap events, as observed at HERA. A phenomenological QCD evolution equation is suggested to calculate the basic characteristics of the large rapidity gap events. The increase of parton densities at small $x$ as well as new means to disentangle experimentally soft and hard physics are considered. We discuss constraints on the increase of deep inelastic amplitudes with $Q^2$ derived from the inconsistency of QCD predictions for inclusive and exclusive processes and from unitarity of the S matrix for collisions of wave packets. New ways to probe QCD physics of hard processes at large longitudinal distances and to answer the long standing problems on the origin of the Pomeron are suggested. Unresolved problems and perspectives of small $x$ physics are also outlined.
