description: We consider a single Minkowski brane sandwiched in between two copies of anti-de Sitter space. We allow the bulk Planck mass and cosmological constant to differ on either side of the brane. Linearised perturbations about this background reveal that gravity can be modified in the infra-red. At intermediate scales, the braneworld propagator mimics four-dimensional GR in that it has the correct momentum dependance. However it has the wrong tensor structure. Beyond a source dependant scale, we show that quadratic brane bending contributions become important, and conspire to correct the tensor structure of the propagator. We argue that even higher order terms can consistently be ignored up to very high energies, and suggest that there is no problem with strong coupling. We also consider scalar and vector perturbations in the bulk, checking for scalar ghosts.

description: Competitive mechanisms contribute to image contrast from dislocations in annular dark field scanning transmission electron microscopy ADF STEM. A clear theoretical understanding of the mechanisms underlying the ADF STEM contrast is therefore essential for correct interpretation of dislocation images. This paper reports on a systematic study of the ADF STEM contrast from dislocations in a GaN specimen, both experimentally and computationally. Systematic experimental ADF STEM images of the edge character dislocations revealed a number of characteristic contrast features that are shown to depend on both the angular detection range and specific position of the dislocation in the sample. A theoretical model based on electron channelling and Bloch wave scattering theories, supported by multislice simulations using Grillo s strain channelling equation, is proposed to elucidate the physical origin of such complex contrast phenomena.

description: Maxwell's multipoles are a natural geometric characterisation of real functions on the sphere (with fixed $\ell$). The correlations between multipoles for gaussian random functions are calculated, by mapping the spherical functions to random polynomials. In the limit of high $\ell,$ the 2-point function tends to a form previously derived by Hannay in the analogous problem for the Majorana sphere. The application to the cosmic microwave background (CMB) is discussed.

Degradation of polychlorinated biphenyl (PCB) metabolites : directed evolution and enzymatic fortuity
Creators: name: Fortin, Pascal
Publisher: name: University of British Columbia
Year: 2010

description: A multi-faceted approach was used to investigate and overcome the PCB-degrading limitations of the Bph enzymes, responsible for the catabolism of biphenyl. First, the reactivities of four evolutionarily divergent extradiol dioxygenases towards mono-, di- and trichlorinated 2,3-dihydroxybiphenyls (DHBs) were investigated: 2,3-dihydroxybiphenyl dioxygenase (EC 1.13.11.39) from Burkholderia xenovorans sp. LB400 (DHBD[sub LB400]), DHBD[sub P6]-I and DHBD[sub P6]-III from Rhodococcus globerulus P6 and 2,2',3-trihydroxybiphenyl dioxygenase from Sphingomonas sp. RW1 (THBD[sub RW1]). The specificity of each enzyme for particular DHBs differed by up to 3 orders of magnitude. Moreover, each enzyme cleaved at least one of the tested chlorinated DHBs better than DHB. However, no enzyme was able to cleave 2',6'-diCl DHB or 3,4-DHB, two recalcitrant PCB metabolites. In the second facet of the study, biological selections were designed to facilitate the engineering of PCB-degrading enzymes via directed evolution. Although these selections failed to link the desired activities to host cell viability, they showed promise for other biocatalysts. In addition, a broadly useful high-throughput colorimetric screen was developed. The latter was applied to increase the specificity of DoxG, an extradiol dioxygenase from Pseudomonas sp. CI8, for 3,4-DHB. A single round of directed evolution yielded DOXG[sub SMA2], a variant that cleaved 3,4-DHB ∼1000-fold more specifically than the wild-type enzyme. DOXG[sub SMA2] contained three substituted residues: L190M, S191W and L242S. The crystal structure of the DoxG:3,4-DHB binary complex indicates that residues at position 190 and 242 occur on opposite sides of the DHB-binding pocket and may interact directly with the distal ring of the substrate. Kinetic analyses revealed that the substitutions are anti-cooperative. Finally, characterization of BphK, the glutathione S-transferase from the bph pathway of B. xenovorans sp. LB400, revealed that the enzyme catalyzes the glutathione-dependant dehalogenation of certain inhibitory CI HOPDAs. BphK catalyzed the dechlorination of 3-Cl HOPDA with a specificity constant of ~10⁴ M⁻¹s⁻¹ in a reaction that utilized a ternary complex mechanism and 2 equivalents of GSH. The identified product of the reaction, HOPDA, is the substrate of the hydrolase from the bph pathway. The relatively low specificity constant of BphK for 3-Cl HOPDAs corroborate genetic evidence that the enzyme was recently recruited to the bph pathway to facilitate PCB degradation.

description: This article is devoted to the study of two-dimensional Bose gases harmonically confined. We first summarize their equilibrium properties. For such a gas above the critical temperature, we also derive the frequencies and the damping of the collective oscillations and we investigate its expansion after releasing of the trap. The method is well suited to study the collisional effects taking place in the system and in particular to discuss the crossover between the hydrodynamic and the collisionless regimes. We establish the link between the relaxation times relevant for the damping of the collective oscillations and for the time-of-flight expansion. We also evaluate the collision rate and its relationship with the relaxation time.

description: This study presents a comparative evaluation among farmers vs. small, medium and large enterprises perceptions of the Senador Nilo Coelho and Maria Teresa Irrigated Perimeters in the São Francisco Valley on the adoption of water saving irrigation technologies. The evaluation is carried on by interviewing producers in a field study. All obtained information in questions related to installation and maintenance costs and productivity of the adopted technologies by producers and other available technologies were used to obtain the results presented in this study. Results show that there is some utilization among entrepreneurs of modern irrigation systems. However, adoption rates are low and the knowledge is not present among all producers. For such farmers, the utilization of inadequate irrigation systems is more frequent thus engen-dering in productive inefficiency among farmers.

description: Artificial superlattices designed with ferromagnetic Pr0.85Ca0.15MnO3 insulating layer and ferroelectric Ba0.6Sr0.4TiO3 layer were grown on (100) SrTiO3 substrates. The magnetotransport properties were measured with the current perpendicular to the plane geometry. An increase in magnetoresistance (MR), with no significant low field effect, was observed as the number of ferroelectric Ba0.6Sr0.4TiO3 layer thickness increases even up to 9 unit cells. For example, the superlattice [(Pr0.85Ca0.15MnO3)10(Ba0.6Sr0.4TiO3)9]25 shows 35 % MR at 100 K, though the Pr0.85Ca0.15MnO3 film was a robust insulator with negligible MR even at high applied magnetic field. This observed large MR cannot be explained by simple interfacial ferromagnetism or by the tunneling magnetoresistance. One possible explanation could be the effect due to the ferroelectric spacer layer and the associated magnetoelectric coupling.

The research based on farmers of Santa Helena (PR), proprietors of areas equal to or higher than 72 (seventy-two) hectares. Data collection was based on interviews with a sample of 40 farmers. As principal results, the most significant attributes for the model were: “pur-pose of the investment”; “conditions of payments” and “funds”. Therefore, the investigated group presents a tendency to accomplish their invest-ments in owning lands due to: financial security, possibilities to pay in instalments and option of using their own funds to cover the debt.

description: Organic agriculture is still inexpressive in Brazil. Its relevance, however, has been growing signiﬁcantly, following international trends. This study analyzes basic characteristics of organic producers, contribut-ing to the present level of knowledge on this matter in Brazil. Using pri-mary data on organic farmers of a region close to Curitiba, in the southern state of Paraná, we identify their main personal, technical and economic characteristics. Our sample farmers were divided into two groups: farm-ers in the stage of conversion toward organic agriculture and farmers already certiﬁed as organic producers. Results indicate the inﬂuence of the education level and of other professional experiences as key elements to characterize organic producers. Other relevant aspects are labor avail-ability and integration of farming, livestock and forest activities.
Small deformations of polygons

description: We describe the first-order variations of the angles of Euclidean, spherical or hyperbolic polygons under infinitesimal deformations such that the lengths of the edges do not change. Using this description, we introduce a vector-valued quadratic invariant $b$ on the space of those isometric deformations which, for convex polygons, has a remarkable positivity property. We give two geometric applications. The first is an isoperimetric statement for hyperbolic polygons: among the convex hyperbolic polygons with given edge lengths, there is a unique polygon with vertices on a circle, a horocycle, or on one connected component of the space of points at constant distance from a geodesic, and it has maximal area. The second application is a new proof of the infinitesimal rigidity of convex polyhedra in the Euclidean space, and a new rigidity result for polyhedral surfaces in the Minkowski space. Finally we indicate how the invariant $b$ can be used to define natural metrics on the space of convex spherical (or hyperbolic) polygons with fixed edge lengths. Those metrics are related to known (and interesting) metrics on the space of convex polygons with given angles in the plane.

description: The farm is each time more recognized as an object of complex study. This if becomes important when the farm is the object to supply an advice of orientation or an aid to the management, or the scope of a plan of agricultural development. For the dairy farms in agricultural bor-ders of the Amazon, characterized by an important diversity of operation mode, the modeling of the diversity with the elaboration of typologies is an important stage for the organization of the agricultural develop-ment. From the case of dairy farms in Uruará municipio, situated on the Transamazonian frontier region, ﬁve main types of systems of milk production and theirs trajectories had been identiﬁed. Associating these two typologies, it was possible to identify the main dynamics within the diversity of the dairy systems, which represent principal evolutions between groups of farms. The results emphasize the importance of socio-economics factors for the installation and the development of the dairy production. Inside this context, proposals can be formulated to promote the beginning of the dairy production, its stability and the improvement of the conditions of production.

description: Estimating the temperature and mass of dust in high-$z$ galaxies is essential for discussions of the origin of dust in the early Universe. However, this suffers from limited sampling of the infrared spectral-energy distribution. Here we present an algorithm for deriving the temperature and mass of dust in a galaxy, assuming dust to be in radiative equilibrium. We formulate the algorithm for three geometries: a thin spherical shell, a homogeneous sphere, and a clumpy sphere. We also discuss effects of the mass absorption coefficients of dust at ultraviolet and infrared wavelengths, $κ_{\rm UV}$ and $κ_{\rm IR}$, respectively. As an example, we apply the algorithm to a normal, dusty star-forming galaxy at $z=7.5$, A1689zD1, for which three data points in the dust continuum are available. Using $κ_{\rm UV}=5.0\times10^4$ cm$^2$ g$^{-1}$ and $κ_{\rm IR}=30(λ/100μm)^{-β}$ cm$^2$ g$^{-1}$ with $β=2.0$, we obtain dust temperatures of 38--70~K and masses of $10^{6.5-7.3}$ M$_\odot$ for the three geometries considered. We obtain similar temperatures and masses from just a single data point in the dust continuum, suggesting the usefulness of the algorithm for high-$z$ galaxies with limited infrared observations. In the clumpy-sphere case, the temperature becomes equal to that of the usual modified black-body fit, because an additional parameter describing the clumpiness works as an adjuster. The best-fit clumpiness parameter is $ξ_{\rm cl}=0.1$, corresponding to $\sim10$\% of the volume filling factor of the clumps in this high-$z$ galaxy if the clump size is $\sim10$ pc, similar to that of giant molecular clouds in the local Universe.

description: This article is about “local agro-food systems” (LAS), clusters of activities of food production where primary production, processing outlets and marketing units are observed. Representing an extension to rural questions of the approaches which relate the possibilities of local and regional development to aspects like proximity, institutions and local ar-ticulations, this form of analysis emphasizes the importance of specific lo-cal resources, particularly the environmental and socio-cultural ones. The subject of LAS is taken in an analysis of mariculture in Santa Catarina, a sector in which this state has reached a remarkable position mainly as a producer of mollusks. The analysis highlights the importance of factors relating to “capital” in its human, social and natural forms, noticed along the coast of Santa Catarina, and points out the character of “resource specific” attached to the network of relationships behind the growth of mariculture, a network which is in itself an important innovation.
Critical behavior and magnetocaloric effect across the magnetic transition in Mn$_{1+x}$Fe$_{4-x}$Si$_{3}$

description: The nature of the magnetic transition, critical scaling of magnetization, and magnetocaloric effect in Mn$_{1+x}$Fe$_{4-x}$Si$_{3}$ ($ x =$ 0 to 1) are studied in detail. Our measurements show no thermal hysteresis across the magnetic transition for the parent compound which is in contrast with the previous report and corroborate the second order nature of the transition. The magnetic transition could be tuned continuously with Mn substitution at the Fe site. The Mn substitution leads to a linear increase in the unit cell volume and a slight reduction in the effective moment. A detailed critical analysis of the magnetization data for $x = 0.0$ and 0.2 is performed in the critical regime using the modified Arrott plots, Kouvel-Fisher plot, universal curve scaling, and scaling analysis of magnetocaloric effect. The magnetization isotherms follow modified Arrott plots with critical exponent ($β\simeq 0.308$, $γ\simeq 1.448$, and $δ\simeq 5.64$) for the parent compound ($x=0.0$) and ($β\simeq 0.304$, $γ\simeq 1.445$, and $δ\simeq 5.64$) for $x = 0.2$. The Kouvel-Fisher and universal scaling plots of the magnetization isotherms further confirm the reliability of our critical analysis and values of the exponents. These values of the critical exponents are found to be same for both the parent and doped samples which do not fall under any of the standard universality classes. A reasonable magnetocaloric effect $ΔS_{\rm m}\simeq-6.67$~J/Kg-K and -5.84~J/Kg-K for $x= 0.0$ and 0.2 compounds, respectively, with a huge relative cooling power ($RCP \sim 700$~J/Kg) for 9~T field change is observed. The universal scaling of magnetocaloric effect further mimics the second order character of the magnetic transition. The obtained critical exponents from the critical analysis of magnetocaloric effect agree with the values deduced from the magnetic isotherm analysis.

description: Cadmium Zinc Telluride (CZT) detectors are having a major impact on the field of hard X-ray astronomy. Without the need for cryogenic cooling they achieve good spatial and energy resolutions over the broad energy range from 10 keV to 600 keV. In this paper, we briefly review the historical development of detectors used in X-ray astronomy. Subsequently, we present an evaluation of CZT detectors from the company Imarad. The standard 2x2x0.5 cm detectors, contacted with 8x8 In pixels and an In cathode, exhibit FWHM energy resolutions of 7 keV at 59 keV, and 10 keV at 662 keV. A direct measurement of the 662 keV photopeak efficiency gives 67%. We have started a detailed study of the performance of Imarad detectors depending on surface preparation, contact materials, contact deposition, post-deposition detector annealing, and detector passivation techniques. We present first results from contacting detectors with Cr, Ag, Au, and Pt.

Hepatic biotransformation of lithocholic acid : role of cytochrome P450 enzymes

Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the present study was to investigate the in vitro biotransformation of lithocholic acid (3α-hydroxy-5β-cholanoic acid, LCA). A validated and optimized method to analyze metabolite formation was developed using liquid chromatography-electrospray mass spectrometry (LC/MS). LCA (0.5-300 μM) was incubated with 0.5 mg/ml of hepatic microsomal protein (untreated male Wistar rats) for 30 min in a reaction mixture consisting of 1 mM NADPH and 46.5 mM potassium phosphate buffer at pH 7.4. LCA metabolites were resolved using a LC/MS and XTerra™ MS C₁₈ (2.1 mm ∗ 150 mm, 3.5 mm) column. The major metabolites were murideoxycholic acid (MDCA), isolithocholic acid (ILCA), and 3-ketocholanic acid (3KCA). Minor metabolites were β-muricholic acid (β-MCA), 6-ketolithocholic acid (6KLCA) and ursodeoxycholic acid (UDCA) and also included, M-1 to M-5, which were not identified. Recovery of all metabolite standards, except for 3KCA (60%), was between 80-100%. Metabolite formation was not observed in the absence of NADPH, with boiled microsomes, or following carbon monoxide treatment. Formation of MDCA, ILCA, UDCA and 6KLCA followed typical Michaelis-Menten kinetics. To identify the cytochrome P450 (CYP) enzymes involved in the formation of LCA metabolites, hepatic microsomes prepared from rats (Long Evans) treated with inducers including 3-methylcholanthrene (MC, 25 mg/kg bw/day ∗ 4 days), phenobarbital (PB, 75 mg/kg bw/day ∗ 4 days) and dexamethasone (DEX, 100 mg/kg bw/day x 4 days) were used. Formation of MDCA and ILCA was decreased with all three inducer treatments and formation of 3KCA was increased with DEX treatment suggesting that CYP3A is involved in formation of 3KCA, and non-inducible CYP enzymes catalyze formation of MDCA and ILCA. Metabolite formation was greater with male than female rat liver microsomes. Rabbit polyspecific anti-rat CYP2C IgG inhibited MDCA formation by 50% and polyspecific anti-rat CYP3A IgG inhibited 3KCA formation by 50%. Anti-rat CYP3A IgG inhibited MDCA, ILCA and 6KLCA formation partially, but inhibited M-1 and M-3 formation completely. Monospecific anti-rat CYP2C11 IgG was not effective in inhibiting the formation of any metabolites. In summary, the results demonstrate the involvement of CYP2C and CYP3A enzymes in rat hepatic LCA biotransformation.

The purpose of this analysis is to determine whether and how they represent different shades of meaning, some nuanced, some distinctive. This allows for their further systematization and the identification of terminological synonymy. The discussion shows that terminological choices might be necessary - not only between „man“ and „human“ or between „dialogue“ and „dialog“, but also between „cooperation“ and „collaboration“ as well as „dialog“ and „communication“. This still leaves a considerable number of terminological options which can be assigned to different facets of human-computer interaction.

description: We interact with usernames every day to communicate on the Internet. We are so familiar with this practice that it seems banal and we therefore fail to see the political implications associated with it. This article aims to help uncover this political dimension of the username. At first, the article follows the argumentation of two texts by Jacques Derrida, from where I establish a connection between the phenomena of proper names and usernames. Derrida deconstructed the founding act of American Independence to work out the role of the signature of proper names. He does the same with Friedrich Nietzsche's proper name to show that proper names play a far greater role in political processes than we might expect. In this context, the modern state is disclosed as an archive and administrator of proper names, while the new phenomenon of the username evades this state power and itself has the institutional potential to become powerful. Because access by the state through verification of names fails with the username, people are more difficult to identify in digital space. The state archive therefore can’t exercise political power over usernames. At the same time, the lack of verification of a username creates the potential for new institutional forces which leads to a conflict with the modern state. This topic is illustrated using the username Q and the politically explosive QAnon movement. Lastly the article points to the conclusion that the phenomenon of usernames is shifting our institutional structures and questioning our beliefs about the modern state, identity and truth.

description: Engineering education usually includes the acquisition of a foreign language for a transnational professional discourse. Engineering education also involves the acquisition of competencies to compose functional technical systems from component parts. This paper provides a conceptual and empirical exploration of a synergistic effect between these two learning processes. It proposes that engineering education draw upon and incorporates this synergy. A pilot training course confirms that this leads to a faster development of the overall engineering knowledge system. This training course implements the conceptual finding according to which the process can be integrated on the model of language learning: to learn mechanics. i.e. kinematics, is like learning English as a foreign language. The grammar of sentence formation and the grammar for the effective technical placement of things teach engineers about symbolic and conceptual order, what the language of mechanics is and how it differs from the language of electronics, and how, for example, this difference needs to be accommodated in the field of mechatronics.

Application of technical means

description: This article examines the concept of "technical means" in the framework of criminal proceedings, both in science and at the legislative level, as well as the types of technical means used in criminal proceedings (search tools, fixation devices, research methods, auxiliary methods, etc.), as well as the general and special conditions and rules of application of these means. The works of prominent specialists in the field of criminal procedure and forensic science on this topic were studied. The study examines the norms of criminal procedure legislation related to the use of technical means, including the Russian Federation's Code of Criminal Procedure and other federal laws. The methodological basis of the article is the general scientific and especially the complex of reasoning-related methods, including such methods as synthesis, analysis, deduction, induction, analogy, formal-legal method, method of interpretation of legal norms and other methods of research activity. As a result of their work, the authors conclude that there is no commonly accepted definition of "technical means" in Russian criminal procedure studies. Each author's definition has its own differences and peculiarities in defining what constitutes a technical means. At the same time, they proceed from the differences related to the purpose of such means and the conditions of their application. At the legislative level, there is no definition of technical means at all. The standing orders that regulate the rules and conditions for the use of these tools are "scattered" throughout the criminal procedure legislation and are not fully coordinated with each other, which is a problem. The types of technical means are also not defined by law, but the issue has been sufficiently developed in academic circles and researched in forensic science. Based on the foregoing, the author considers it appropriate to introduce a unified norm governing the institution of "technical means" into the criminal procedural legislation, which will contain a list of subjects entitled to use these technical means, rules and conditions for their use and other provisions.

description: Unsupervised domain adaptation addresses the problem of transferring knowledge from a well-labeled source domain to an unlabeled target domain where the two domains have distinctive data distributions. Thus, the essence of domain adaptation is to mitigate the distribution divergence between the two domains. The state-of-the-art methods practice this very idea by either conducting adversarial training or minimizing a metric which defines the distribution gaps. In this paper, we propose a new domain adaptation method named Adversarial Tight Match (ATM) which enjoys the benefits of both adversarial training and metric learning. Specifically, at first, we propose a novel distance loss, named Maximum Density Divergence (MDD), to quantify the distribution divergence. MDD minimizes the inter-domain divergence ("match" in ATM) and maximizes the intra-class density ("tight" in ATM). Then, to address the equilibrium challenge issue in adversarial domain adaptation, we consider leveraging the proposed MDD into adversarial domain adaptation framework. At last, we tailor the proposed MDD as a practical learning loss and report our ATM. Both empirical evaluation and theoretical analysis are reported to verify the effectiveness of the proposed method. The experimental results on four benchmarks, both classical and large-scale, show that our method is able to achieve new state-of-the-art performance on most evaluations. Codes and datasets used in this paper are available at {\it github.com/lijin118/ATM}.

description: Changes in educational paradigms have affected the understanding of how individuals learn. The emergence of Covid-19 has created unprecedented disruption in the education systems. This study attempts to analyse students' perceptions of their learning profile before and after Covid-19, using two different cohorts of students from five schools. Participated in October 2019 (first application) 369 students, and in November 2021 (second application) 294 students. These are students of two educational cycles: grades 7-9 and 10-12. The Effective Lifelong Learning Inventory questionnaire has seven dimensions: ‘moving and learning’, ‘critical curiosity’, ‘making sense’, ‘creativity’, ‘learning relationships’, ‘strategic awareness’, ‘resilience’; and it was administered to understand how students self-assess their learning profile. Descriptive and inferential statistics were calculated to analyse the data and detect possible differences in the learning profiles. The results show that students in grades 7-9 seem to have been the most affected by Covid-19 (means were statistically significant in all dimensions except ‘resilience’) when compared to students in grades 10-12 (statistically significant only in ‘critical curiosity’, ‘learning relationships’ and ‘meaning making’ dimensions). In conclusion, the learning profiles have changed between the applications in both cycles. A higher percentage of students rated themselves worse in almost all dimensions in the second application. However, the increased autonomy during Covid-19 could explain the average increases in 'resilience' in grades 7-9 and 'creativity' in grades 10-12 from the first to the second application. Keywords: grades 7-9; grades 10-12; learning power; learning provisions; effective lifelong learning inventory; covid-19.

description: It has recently been shown that all causal correlations between two parties which output each one bit, a and b, when receiving each one bit, x and y, can be expressed as convex combinations of local correlations (i.e., correlations that can be simulated with local random variables) and non-local correlations of the form a+b=xy mod 2. We show that a single instance of the latter elementary non-local correlation suffices to simulate exactly all possible projective measurements that can be performed on the singlet state of two qubits, with no communication needed at all. This elementary non-local correlation thus defines some unit of non-locality, which we call a nl-bit.

description: BESIII is a multipurpose spectrometer optimized for physics in the tau-charm energy region. Both detector and accelerator are undergoing an upgrade program, that will allow BESIII to run until 2029. A major upgrade is the replacement of the inner drift chamber with a new detector based on Cylindrical Gas Electron Multipliers to improve both the secondary vertex reconstruction and the radiation tolerance. The CGEM-IT will be composed of three coaxial layers of cylindrical triple GEMs, operating in an Ar$\,$+$\,$iC$_4$H$_{10}$ (90:10) gas mixture with field and gain optimized to maximize the spatial resolution. The new detector is readout with innovative TIGER electronics produced in 110$\,$nm CMOS technology. The front end is a custom designed 64$\,$channel ASIC featuring a fully digital output and operated in trigger-less mode. It can provide analog charge and time measurements with a TDC time resolution better than 100$\,$ps, that will allow to operate in $μ$TPC mode. Before the installation inside BESIII, foreseen in 2021, a long standalone data taking is ongoing at the Institute of High Energy Physics in Beijing; currently, the first two cylindrical chambers are available for the test, and are used to complete the integration between the detector and the electronics and to assess the required performance. In this proceeding a description of the CGEM-IT project, the TIGER features and performance, and the results of the analysis of first cosmic ray data taking will be presented. Focus will be given on the strip analysis, from which it is possible to measure the basic properties of the detector, and the cluster analysis. The first preliminary results on efficiency and spatial resolution will be also presented.

description: We consider QCD with one massless quark and one heavy quark in a finite volume of linear extent L_0 ~ 0.2 fm. In this situation, HQET represents an expansion in terms of 1/z=1/(m L_0), which we test by a non-perturbative computation of quenched current matrix elements and energies, taking the continuum limit of lattice results. These are seen to approach the corresponding renormalization group invariant matrix elements of the static effective theory as the quark mass becomes large. We are able to obtain estimates of the size of the 1/m-corrections to the static theory, which are also of practical relevance in our recent strategy to implement HQET non-perturbatively by matching to QCD in a finite volume.

"Little remark"
Transformation of dramatic language

description: This article is devoted to the study of the reception and image of virtual communication technologies in modern drama for teenagers. It is obvious that digital technologies in plays aimed at young audiences are becoming a marker of modernity and a characteristic detail of a technogenic civilization that generates conflict situations. The portrayal of young heroes and heroines - the same age as the prospective viewer - is impossible without recreating the realities of modern virtual communication. It will be shown in this article that the appeal of modern playwrights to these problems entails a transformation of the dramatic language, caused by the need to take into account the social and psychological characteristics of the addressee. This research studies plays that were included in the short lists of 12+ of the "Little Remark" award for the period of its existence (2018-2021). Statistical and comparative methods were used, as well as the method of immanent analysis of the work. In total, 31 plays were considered, of these, 19 were relevant. The languages of virtual communication are presented in these plays as: 1) a way to identify one's era and, as a result, oneself in heroic characters; 2) a metaphor for building a hero's identity; 3) symbol of a reality that differs from the empirically given world; 4) a method of modeling a dramatic picture using the signs of modernity and a new type of communication with the viewer. Technologies can be perceived as a source of conflict situations, but also as a means of resolving these conflicts. Despite the contradictory attitude of the authors of the plays to the depicted phenomenon, it can be stated that the appeal to new technologies of dialogue that do not correspond to the traditional dialogical forms of drama can become the basis for a further development of the dramatic language as a whole.
