description: Nodal lines inside the momentum space of three-dimensional crystalline solids are topologically stabilized by a $π$-flux of Berry phase. Nodal-line rings in $\mathcal{PT}$-symmetric systems with negligible spin-orbit coupling (here described as "nodal class AI") can carry an additional "monopole charge", which further enhances their stability. Here, we relate two recent theoretical advancements in the study of band topology in nodal class AI. On the one hand, cohomology classes of real vector bundles were used to relate the monopole charge of nodal-line rings to their linking with nodal lines formed among the occupied and among the unoccupied bands. On the other hand, homotopy studies revealed that the generalization of the Berry-phase quantization to the case of multiple band gaps defines a non-Abelian topological charge, which governs the possible deformations of the nodal lines. The present work has three aims. First, we present how to efficiently wield the recently discovered non-Abelian topological charge. Second, we apply these methods to present an independent proof of the relation between the monopole charge and the linking structure, including all the fragile-topology exceptions. Finally, we show that the monopole charge flips sign when braided along a path with a non-trivial Berry phase. This facilitates a new type non-Abelian "braiding" of nodal-line rings inside the momentum space, that has not been previously reported. The work begins with a brief review of $\mathcal{PT}$-symmetric band topology, and the geometric arguments employed in our theoretical analysis are supplemented in the appendices with formal mathematical derivations.

description: Gewächshäuser sind begehbare Bauten mit einer lichtdurchlässigen Außenhülle, die die erforderlichen Wachstumsbedingungen für eine ganzjährige Pflanzenproduktion schaffen sollen. Die Wachstumsfaktoren Licht, Temperatur, Luttfeuchte, Luftzusammensetzung und Wasser müssen optimal so zur Verfügung gestellt werden, daß unter weitestgehender Schonung der Umwelt möglichst geringer Aufwand für Investition und Unterhaltung entsteht. Ziele der technischen Entwicklung müssen sein:
- die ökonomische Optimierung
- die Rationalisierung
- die ökologische Optimierung.
Der Gartenbau hat eine erhebliche Bedeutung im Agrarbereich Deutschlands, insbesondere durch die intensive Produktion von Zierpflanzen, Gemüse, Obst und Baumschulpflanzen. Auf etwa 1% der landwirtschaftlich genutzten Fläche werden etwa 41% der Erlöse aus pflanzlicher Produktion erzielt. Jeder Bundesbürger kauft jährlich für durchschnittlich 120,- DM Zierpflanzen und ißt jährlich 80 bis 90 kg Gemüse. Die meisten Zierpflanzen werden im Sommer und Winter in Gewächshäusern produziert, ebenso wichtige Gemüsearten wie Tomaten, Gurken und Paprika. In Deutschland gibt es heute etwa 4.300 ha Gewächshausfläche, in den Niederlanden 9.800 ha, in Italien und Spanien jeweils ca. 23.000 ha.

description: In this paper, multiple instance learning (MIL) algorithms to automatically perform root detection and segmentation in minirhizotron imagery using only image-level labels are proposed. Root and soil characteristics vary from location to location, thus, supervised machine learning approaches that are trained with local data provide the best ability to identify and segment roots in minirhizotron imagery. However, labeling roots for training data (or otherwise) is an extremely tedious and time-consuming task. This paper aims to address this problem by labeling data at the image level (rather than the individual root or root pixel level) and train algorithms to perform individual root pixel level segmentation using MIL strategies. Three MIL methods (multiple instance adaptive cosine coherence estimator, multiple instance support vector machine, multiple instance learning with randomized trees) were applied to root detection and compared to non-MIL approches. The results show that MIL methods improve root segmentation in challenging minirhizotron imagery and reduce the labeling burden. In our results, multiple instance support vector machine outperformed other methods. The multiple instance adaptive cosine coherence estimator algorithm was a close second with an added advantage that it learned an interpretable root signature which identified the traits used to distinguish roots from soil and did not require parameter selection.

description: Integrated task and motion planning problems describe a multi-modal state space, which is often abstracted as a set of smooth manifolds that are connected via sets of transitions states. One approach to solving such problems is to sample reachable states in each of the manifolds, while simultaneously sampling transition states. Prior work has shown that in order to achieve asymptotically optimal (AO) solutions for such piecewise-smooth task planning problems, it is sufficient to double the connection radius required for AO sampling-based motion planning. This was shown under the assumption that the transition sets themselves are smooth. The current work builds upon this result and demonstrates that it is sufficient to use the same connection radius as for standard AO motion planning. Furthermore, the current work studies the case that the transition sets are non-smooth boundary points of the valid state space, which is frequently the case in practice, such as when a gripper grasps an object. This paper generalizes the notion of clearance that is typically assumed in motion and task planning to include such individual, potentially non-smooth transition states. It is shown that asymptotic optimality is retained under this generalized regime.

description: The purpose of this study was to explore the roles of educational policies and cultural practices in limiting opportunities and violating rights of pregnant and parenting school-aged adolescents in Thailand. Cultural attitudes continue to play an important role in restricting khun mae wai sai’s [adolescent mothers] right to equal educational opportunity. Analysis of the study was based on a close examination of past and existing policies regarding school-aged adolescent mothers in conjunction with major themes uncovered from in-depth personal interviews with various stakeholders. A total of thirty one individuals from three major ministries overseeing the issue of adolescent pregnancy participated: principals and teachers, government officials, and NGOs workers were interviewed in Bangkok and other nearby provinces. Policies and programs aimed at preventing unintended adolescent pregnancies and/or providing protection for adolescent mothers and their babies that have been successfully implemented in other countries were identified and suggested for possible implementation in Thailand. The result of this study suggests that the Thai government along with the help from other stakeholders are crucial to guarantee that the educational rights of pregnant and parenting adolescents and their children are protected and realized.

Efficient computation of the Euler-Kronecker constants of prime cyclotomic fields

Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)

description: We introduce a new algorithm, which is faster and requires less computing resources than the ones previously known, to compute the Euler-Kronecker constants $\mathfrak{G}_q$ for the prime cyclotomic fields $\mathbb{Q}(ζ_q)$, where $q$ is an odd prime and $ζ_q$ is a primitive $q$-root of unity. With such a new algorithm we evaluated $\mathfrak{G}_q$ and $\mathfrak{G}_q^+$, where $\mathfrak{G}_q^+$ is the Euler-Kronecker constant of the maximal real subfield of $\mathbb{Q}(ζ_q)$, for some very large primes $q$ thus obtaining two new negative values of $\mathfrak{G}_q$: $\mathfrak{G}_{9109334831}= -0.248739\dotsc$ and $\mathfrak{G}_{9854964401}= -0.096465\dotsc$ We also evaluated $\mathfrak{G}_q$ and $\mathfrak{G}^+_q$ for every odd prime $q\le 10^6$, thus enlarging the size of the previously known range for $\mathfrak{G}_q$ and $\mathfrak{G}^+_q$. Our method also reveals that difference $\mathfrak{G}_q - \mathfrak{G}^+_q$ can be computed in a much simpler way than both its summands, see Section 3.4. Moreover, as a by-product, we also computed $M_q=\max_{χ\ne χ_0} \vert L^\prime/L(1,χ) \vert $ for every odd prime $q\le 10^6$, where $L(s,χ)$ are the Dirichlet $L$-functions, $χ$ run over the non trivial Dirichlet characters mod $q$ and $χ_0$ is the trivial Dirichlet character mod $q$. As another by-product of our computations, we will also provide more data on the generalised Euler constants in arithmetic progressions. The programs used to performed the computations here described and the numerical results obtained are available at the following web address: \url{http://www.math.unipd.it/~languasc/EK-comput.html}.

description: A hallmark of intelligence in humans and other animals is the ability to engage in complex behaviors geared towards achieving far-removed goals. Such behavior relies on a set of diverse and sophisticated mental processes that are collectively referred to as cognitive or executive in nature. The prefrontal cortex (PFC) has long been considered the primary neural locus for such processes. From humans down to rodents, damage to the PFC has been shown to impair cognition and executive function. In neuropsychiatric disorders such as schizophrenia, dysfunction of the PFC has been strongly linked to cognitive dysfunction.
      PFC functioning however, necessarily relies on interactions within and between networks of interconnected neurons. Across species, the PFC has been anatomically defined as the region of cortex reciprocally connected with the mediodorsal thalamus (MD), a definition that suggests PFC functioning cannot be divorced from that of its main thalamic counterpart. Indeed, an increasing number of studies have demonstrated the involvement of MD in cognitive behaviors. Schizophrenia patients performing cognitive tasks also exhibit decreased MD activity, with growing evidence for decreased functional connectivity with the PFC.
      The studies presented here seek to build on this literature using the mouse as a model organism. Taking advantage of recent tools for temporally- and spatially-restricted manipulations of neural activity we show that a relatively mild and reversible decrease in MD activity is capable of impairing two cognitive behaviors classically shown to be PFC-dependent – behavioral flexibility and working memory. Simultaneously recording MD and PFC activity while mice perform a spatial working memory task, we show task modulations of synchronous MD-PFC activity that are disrupted by a primary decrease in MD activity. Following up on this finding using pathway-specific manipulations of MD-to-PFC and PFC-to-MD neural connections, we provide behavioral and neurophysiological evidence that these circuits serve as distinct neural substrates for working memory maintenance and retrieval. Together, these findings provide causal evidence in support of an association between thalamo-prefrontal dysfunction and cognitive impairment, and may enable the development of more selective therapeutic strategies for cognitive disorders such as schizophrenia.

description: Vectorization is increasingly important to achieve high performance on modern hardware with SIMD instructions. Assembly of matrices and vectors in the finite element method, which is characterized by iterating a local assembly kernel over unstructured meshes, poses difficulties to effective vectorization. Maintaining a user-friendly high-level interface with a suitable degree of abstraction while generating efficient, vectorized code for the finite element method is a challenge for numerical software systems and libraries. In this work, we study cross-element vectorization in the finite element framework Firedrake via code transformation and demonstrate the efficacy of such an approach by evaluating a wide range of matrix-free operators spanning different polynomial degrees and discretizations on two recent CPUs using three mainstream compilers. Our experiments show that our approaches for cross-element vectorization achieve 30\% of theoretical peak performance for many examples of practical significance, and exceed 50\% for cases with high arithmetic intensities, with consistent speed-up over (intra-element) vectorization restricted to the local assembly kernels.

description: The evolution of the internal granular structure in shear-arrested and shear-flowing states of granular materials is characterized using fabric tensors as descriptors of the internal contact and force networks. When a dilute system of frictional grains is subjected to a constant pressure and shear stress, the bulk stress ratio is well-predicted from the anisotropy of its contact and force networks during transient flow prior to steady shear flow or shear arrest. Although the onset of shear arrest is a stochastic process, the fabric tensors upon arrest are distributed around nearly equal contributions of force and contact network anisotropy to the bulk stress ratio. The distribution becomes seemingly narrower with increasing system size. The anisotropy of the contact network in shear-arrested states is reminiscent of the fabric anisotropy observed in shear-jammed packings.

description: We report the Transiting Exoplanet Survey Satellite discovery of three small planets transiting one of the nearest and brightest M dwarf hosts to date, TOI-270 (TIC 259377017; K-mag 8.3; 22.5 parsec). The M3V-type star is transited by the super-Earth-sized TOI-270 b (1.247+0.089-0.083 R_earth) and the sub-Neptune-sized exoplanets TOI-270 c (2.42+-0.13 R_earth) and TOI-270 d (2.13+-0.12 R_earth). The planets orbit close to a mean-motion resonant chain, with periods (3.36, 5.66, and 11.38 days) near ratios of small integers (5:3 and 2:1). TOI-270 is a prime target for future studies since: 1) its near-resonance allows detecting transit timing variations for precise mass measurements and dynamical studies; 2) its brightness enables independent radial velocity mass measurements; 3) the outer planets are ideal for atmospheric characterisation via transmission spectroscopy; and 4) the quiet star enables future searches for habitable zone planets. Altogether, very few systems with small, temperate exoplanets are as suitable for such complementary and detailed characterisation as TOI-270.

description: In my dissertation, I advance and defend a broad account of reasoning, including both the nature of inference and the structure of our reasoning systems. With respect to inference, I argue that we have good reason to consider a unified account of the cognitive transitions through which we attempt to figure things out. This view turns out to be highly inflationary relative to previous philosophical accounts of inference, which, I argue, fail to accommodate many instances of everyday reasoning. I argue that a cognitive transition’s status as an inference, in this broad sense, depends on the subject’s taking the conclusion of the inference— a new, revised, or supposed belief— to be the output of a rational thought process. Furthermore, taking such a belief to be the output of a rational thought process consists in its accompaniment by the feeling of correctness to the subject, which I call the assent affect. With respect to the structure of our reasoning systems, I defend a dual process model of reasoning by addressing certain alleged deficiencies with such accounts. I argue that the assent affect— or more precisely its absence— is a strong candidate to serve as the triggering condition of our more deliberate type 2 reasoning processes. That is, a subject’s more effortful reasoning processes engage with a problem when the output of a type 1 intuition is not accompanied by the assent affect. A subject will think harder about a problem, in other words, when they do not feel confident that they have gotten to the bottom of it. This account, I argue, fits well with both empirical and theoretical claims about the interaction of dual reasoning processes. In this dissertation, I use the assent affect to solve puzzles about both the nature of inferences and the structure of our reasoning systems. Puzzles in rationality become easier to solve when our intellectual feelings are not excluded from the picture.

description: We solve a continuing controversy when dealing with density fluctuations in open Friedman-Robertson-Walker universes, on the physical relevance of a class of exponential modes. We show explicitly and rigorously that these modes enter the expansion of quantum fields. In the maximally symmetric de Sitter case, encountered in inflationary models, they are excited for fields with mass below a critical value. They are seen to be responsible for the breaking of the de Sitter symmetry for a massless field. We provide an exact calculation of the power spectrum for any mass. Our method is free of the divergences that appear in earlier treatments. We extend the construction to a generic open FRW universe.

That's Not What Your Friends Say: Does Self-reported Posttraumatic Growth Translate into Friend Ratings of Improvement?
Creators: Goorin, Laura
Publisher: name: Columbia University

Subjects: Clinical psychology

description: Posttraumatic growth (PTG) is a prolific construct under study within both trauma and positive psychology literature alike. Many of these studies rely predominantly on cross-sectional, retrospective self-report data. Recent studies have attempted to subject PTG to more rigorous scientific standards of measurement. In this study, we examined posttraumatic growth measured longitudinally among survivors of the September 11th, 2001 terrorist attack, in order to explore whether participants' reports of posttraumatic growth were associated with, supported or contradicted by friend ratings of improvement. In this context, participant-reported posttraumatic growth was consistently linked with friend ratings of deteriorating functioning, providing evidence that posttraumatic growth is undermined by friend ratings. These findings suggest that self-reported PTG may inadequately predict functioning as rated by alternative, more objective measures, and that PTG may reflect negative psychological adjustment.

description: Unter dem Begriff Tiefengas wird Erdgas verstanden, das überwiegend aus Methan besteht und dessen Mutter- und Speichergesteine in Tiefenbereichen unterhalb der heutigen Ziele der industriellen Exploration (> 7 km) liegen. In Norddeutschland stammen die in den Formationen vom Oberkarbon und Rotliegenden bis zur Trias auftretenden Gaslagerstätten aus organischen Substanzen, die vor etwa 320 Millionen Jahre in oberkarbonischen Sedimenten abgelagert wurden.
Nachdem die Exploration auf Erdöl in der Bundesrepublik eingestellt worden ist und die Förderung aus den noch bestehenden Erdölfeldern nur einen sehr geringen Anteil des deutschen Bedarfs decken kann, werden in naher Zukunft auch die aus dem Oberkarbon sich ableitenden Gaslagerstätten ausexploriert sein. Danach wird die Förderung, die zur Zeit noch immerhin rund 25% unseres Eigenbedarfs decken kann, sehr rasch abnehmen. Falls es nicht gelingt, die Existenz wirtschaftlich interessanter Muttergesteine unterhalb des Oberkarbons und damit auch die Voraussetzungen für Erdgasansammlungen in größerer Tiefe zu konkretisieren, wird der Industriestaat Deutschland in wenigen Jahrzehnten ohne Erdgasförderung aus heimischen Quellen und ohne die sicheren heimischen Reserven an Methan sein, obwohl die Bedeutung des Methans als wichtiger und umweltfreundlicher Energieträger und Chemierohstoff künftig zunehmen wird.

description: The discovery of quadrupole topology opens a new horizon in the study of topological phenomena. However, the existing experimental realizations of quadrupole topological insulators in symmorphic lattices with $π$-fluxes often break the protective mirror symmetry. Here, we present a theory for anomalous quadrupole topological insulators in nonsymmorphic crystals without flux, using 2D sonic crystals with $p4gm$ and $p2gg$ symmetry groups as concrete examples. We reveal that the anomalous quadrupole topology is protected by two orthogonal glide symmetries in square or rectangular lattices. The distinctive features of the anomalous quadrupole topological insulators include: (i) minimal four bands below the topological band gap, (ii) nondegenerate, gapped Wannier bands and special Wannier sectors with gapped composite Wannier bands, (iii) quantized Wannier band polarizations in these Wannier sectors. Remarkably, the protective glide symmetries are well-preserved in the sonic-crystal realizations where higher-order topological transitions can be triggered by symmetry or geometry engineering.

description: We present a model for tail wavelets, a phenomenon also known as "echo" in the literature. The tail wavelet may appear in signal reconnaissances in the merger of binary compact objects, including black holes and neutron stars. We show that the dark matter surrounding the compact objects lead to the speculated tail wavelet following the main gravitational wave (GW). We demonstrate that the radiation pressure of the main wave is fully capable of pushing away the the surrounding matter to some altitude, and splashing down of the matter excites the tail wavelet after ring down of the main wave. We illustrate this idea in a simplified model, where numerical estimations are carried out concerning the specific distribution of the dark matter outside the black hole horizon and the threshold values in accordance with observations. We study the full back reaction of the surrounding dark matter to the metric, and find that the effect is insignificant to the tail wavelets. We find the fine difference between the tail wavelets of a dressed black hole and a bare one. We demonstrate that the tail wavelet can be a natural phenomenon in frame of general relativity, without invoking any modified gravities or quantum effects.
Memory Effects and Macroscopic Manifestation of Randomness

description: It is shown that due to memory effects the complex behaviour of components in a stochastic system can be transmitted to macroscopic evolution of the system as a whole. Within the Markov approximation widely using in ordinary statistical mechanics, memory effects are neglected. As a result, a time-scale separation between the macroscopic and the microscopic level of description exists, the macroscopic differential picture is no a consequence of microscopic non-differentiable dynamics. On the other hand, the presence of complete memory in a system means that all its components have the same behaviour. If the memory function has no characteristic time scales, the correct description of the macroscopic evolution of such systems have to be in terms of the fractional calculus.

description: This dissertation analyzes transformation in early 21st century educational practice through the lens of information technology (IT) use at a private, women's university in Jeddah, Saudi Arabia. Academic and extracurricular Internet use, which is enabled through ubiquitous mobile devices, students' attitudes toward information and communication technology (ICT), and the nature and purpose of their activities in social network sites (SNS) will be discussed alongside critical analysis of peer-to-peer teaching and learning in relation to knowledge production and educational practice. Richly ethnographic discussion delves into emerging global education paradigms that are (re)configuring the experience of women's higher education in Saudi Arabia and influencing women's participation in public, economic, and political spheres from which they might have been previously excluded. This dissertation also seeks to engage bigger questions about young people's intimate relationships with ICTs and the nuances of the networked spaces in which they experience life online as students and citizens coming of age as members of the digital generation.

description: A soliton cellular automaton associated with crystals of symmetric tensor representations of the quantum affine algebra U'_q(A^{(1)}_M) is introduced. It is a crystal theoretic formulation of the generalized box-ball system in which capacities of boxes and carriers are arbitrary and inhomogeneous. Scattering matrices of two solitons coincide with the combinatorial R matrices of U'_q(A^{(1)}_{M-1}). A piecewise linear evolution equation of the automaton is identified with an ultradiscrete limit of the nonautonomous discrete KP equation. A class of N soliton solutions is obtained through the ultradiscretization of soliton solutions of the latter.

description: We investigate the type of dual superconductivity responsible for quark confinement. For this purpose, we solve the field equations of the $U(1)$ gauge-scalar model to obtain the static vortex solution in the whole range without restricting to the long-distance region. Then we use the resulting magnetic field of the vortex to fit the gauge-invariant chromoelectric field connecting a pair of quark and antiquark which was measured by numerical simulations for $SU(2)$ Yang--Mills theory on a lattice. This result improves the accuracy of the fitted value for the Ginzburg--Landau parameter to reconfirm the type I dual superconductivity for quark confinement which was claimed by preceding works based on a fitting using the Clem ansatz. Moreover, we calculate the Maxwell stress tensor to obtain the distribution of the force around the flux tube. This result suggests that the attractive force acts among chromoelectric flux tubes, in agreement with the type I dual superconductivity.

description: Rhogogastera aenescens Mocsáry, 1909
A junior subjective synonym of Tenthredo (Temuledo) finschi finschi W.F. Kirby, 1882, syn. nov.
TYPES. Rhogogastera aenescens Mocsáry, 1909: 19. Syntype (s) Ƥ, “Sibiria orientalis: Ussuri (Kasakewitsh).”. Lectotype Ƥ, hereby designated (Fig. 1). Type locality: “Ussuri Kasakewitsch” [= Russia: Khabarovskiy Kray: Kazakevichevo].
DISCUSSION. After its description, Rhogogastera aenescens has apparently not been mentioned in the literature except by Taeger et al. (2010: 580). One female was found under this name in the HNHM collection (Fig. 1). As Mocsáry did not state the number of specimens, this specimen is selected as the lectotype. It belongs without doubt to Tenthredo (Temuledo) finschi.

Gravity on parallelizable manifold

description: General relativity postulates that the gravity field is defined on a Riemannian manifold. The field equations are $R^μ_ν= 0$ i.e. Ricci's curvature tensor vanishes. The field equations have to be augmented by natural physical requirements like orientability, time orientability and existence of a spinorial structure. Moreover, it is impossible to define the energy of the gravity field only by the metric tensor. We suggest to impose an additional structure and consider parallelizable manifold i.e. manifolds for which a smooth field of frames exists. The derivation of the field equations is by an action principle. A Lagrangian, which is quadratic in the differentials, is defined. The minimum of the action is achieved at a $16 \times 16$ second order quasi linear system. It is of Laplacian type. The system admits a unique exact solution for a centrally symmetric, static and assimptotically flat field. The resulting metric is the celebrated Rosen metric, which is very close to the Schwarzchild metric. The two are intrinsicly different since the scalar curvature of the Schuarzschild metric is zero, in contrast to Rosen's which is positive. The suggested field admits black holes which are briefly discussed.

description: In unserer modernen Gesellschaft, die durch die Fortschritte in den Naturwissenschaften, der Technik und durch weltweiten Handel geschaffen worden ist, hat das Messen eine herausragende Bedeutung. Jede Ware in kleinen oder riesigen Mengen, die ihren Besitzer wechselt - ob Lebensmittel oder elektrische Energie - muß gemessen werden. Selbst der Arzt stützt sich bei der Diagnose oder der Therapie auf Meßwerte, die Aussagen über unseren gesundheitlichen Zustand machen oder die Dosis festsetzen. Das Messen ist also zu einem ganz normalen Bestandteil unseres Lebens geworden.
Die erhöhten Anforderungen an Genauigkeit insbesondere im ,High-Tech'-Bereich und an die Vergleichbarkeit von Messungen setzen genaue und allgemein gültige Einheiten voraus. Um diesen beiden Ansprüchen gerecht werden zu können, versucht man heute die Einheiten auf Fundamentalkonstanten in der Physik zurückzuführen. Soweit wir wissen, sind diese nämlich als unabhängig vom Ort und von der Zeit anzusehen und stellen, wenn immer das in der Praxis mit geringer Meßunsicherheit gelingt, ideale Maße in Naturwissenschaft und Technik dar.
Bekanntlich beruhen alle Messungen in unserem SI-Einheitensystem auf sieben Basiseinheiten, die in dem Bild I wiedergegeben sind. Die drei unabhängigen Basiseinheiten Kilogramm, Sekunde und Kelvin werden durch das Kilogramm-Prototyp seit 1889, seit 1967 durch die Atomuhr und durch die Tripelpunktzelle des Wasser in den metrologischen Staatsinstituten dargestellt. Relativ neu sind die Versuche, das Meter, das Mol und das Ampere auf Fundamentalkonstanten zurückzuführen. Im folgenden soll kurz über den gegenwärtigen Stand dieser Entwicklung berichtet werden.

description: Several years ago, Stefan Pokorski, Manfred Muenz and us outlined a program for calculation of the NLO QCD corrections to the weak radiative B meson decay B -> X_s gamma. Very recently, just before the 60th birthday of Stefan Pokorski, this program has been formally completed. In the present paper, we summarize the existing results and discuss perspectives for further improvement of the accuracy of the Standard Model prediction for BR[ B -> X_s gamma].
