description: The 67 kDa laminin receptor (67LR) is a non-integrin cell surface receptor for laminin (LM) that derives from a 37 kDa precursor (37LRP). 67LR expression is increased in neoplastic cells and correlates with an enhanced invasive and metastatic potentialin many human solid tumors, recommending this receptor as a new promising target for cancer therapy. This is supported by in vivo studies showing that 67LR downregulation reduces tumour cell proliferation and tumour formation by inducing apoptosis. 67LR association with the anti-apoptotic protein PED/PEA-15 activates a signal transduction pathway, leading to cell proliferation and resistance to apoptosis. However, the main function of 67LR is to enhance tumor cell adhesion to the LM of basement membranes and cell migration, two crucial events in the metastasis cascade.Thus, inhibition of 67LR binding to LM has been proved to be a feasible approach to block metastatic cancer cell spread. Despite accumulating evidences on 67LR overexpression in hematologic malignancies, 67LR role in these diseases has not been clearly defined. Here, we review 67LR expression and function in normal and malignant hematopoietic cells, 67LR role and prognostic impact in hematological malignancies and first attempts in targeting its activity.

description: Изложены результаты анализа данных по существующим на сегодняшний день транспортерам для уборки навоза из коровников. Приведена методика расчета экономической эффективности при внедрении новой техники по сравнению с существующей. Рассчитана экономическая эффективность замены навозоуборочных транспортеров типа ТСН-160А и ТШ-300 установками порционного действия из типовых коровников с привязным содержанием животных. Конструктивные особенности установок заключались в разных конструкциях их рабочих органов кареток. Установка УПУН-Ф-320-1 для выгрузки навоза из продольных каналов коровника в поперечный канал, размещенный в его торце, установка УПУН-Ф-320-2 для выгрузки навоза из продольных каналов коровника в поперечный канал, размещенный в центре коровника. При расчете экономической эффективности учитывались следующие затраты: на электроэнергию; амортизационные отчисления от балансовой стоимости; на текущий ремонт и техническое обслуживание; на заработную плату слесарей; на социальные, отраслевые и общехозяйственные нужды. Указаны актуальные ценовые показатели на 2017 год. Отмечен положительный эффект замены существующей техники на новую. Установки порционной уборки навоза менее металлоемки, расходуют меньше электроэнергии и имеют более низкие эксплуатационные затраты.The results of analysis of data on current conveyors for manure disposal from cowbarns are given. The method of new machinery compared to existing one implementation’s economic efficiency calculation is shown. The economic efficiency of manure cleaning conveyors of TSN-160A type and TSH-300 units with batch action installations’ of manure cleaning from the typical design cowbarns with tied animals’ keeping is calculated. Design features of the units were due to different structures of their working bodies the carriages. The UPUN-F-320-1 unit for the manure unloading from cowbarn longitudinal channels in the transverse channel, placed at its end, UPUN-F-320-2 unit for manure discharge from the cowbarn longitudinal channels in the transverse channel placed in the cowbarn’s center. At economic efficiency calculating it was taken into account the following costs: electricity; amortization cost of balance value; current repairs and machinery service; mechanics salary; social, sectoral and total business needs. The actual price for 2017 are shown. The positive effect of the existing equipment with the new one replacement is noted. The manure cleaning’s batch action installations are lesser metal, consume lesser electro power and have lower operating costs.

description: In this correspondence we present a new proof of Holevo's coding theorem for transmitting classical information through quantum channels, and its strong converse. The technique is largely inspired by Wolfowitz's combinatorial approach using types of sequences. As a by-product of our approach which is independent of previous ones, both in the coding theorem and the converse, we can give a new proof of Holevo's information bound.

description: It is shown that, given any finite dimensional, split basic algebra $Λ= KΓ/I$ (where $Γ$ is a quiver and $I$ an admissible ideal in the path algebra $K Γ$), there is a finite list of affine algebraic varieties, the points of which correspond in a natural fashion to the isomorphism types of uniserial left $Λ$-modules, and the geometry of which faithfully reflects the constraints met in constructing such modules. A constructive coordinatized access to these varieties is given, as well as to the accompanying natural surjections from the varieties onto families of uniserial modules with fixed composition series. The fibres of these maps are explored, one of the results being a simple algorithm to resolve the isomorphism problem for uniserial modules. Moreover, new invariants measuring the complexity of the uniserial representation theory are derived from the geometric viewpoint. Finally, it is proved that each affine algebraic variety arises as a variety of uniserial modules over a suitable finite dimensional algebra, in a setting where the points are in one-one correspondence with the isomorphism classes of uniserial modules.

We analyze the phases acquired by the evolved state and show that some of them have a pure quantum mechanical origin. In order to measure one of these phases, we propose a simple experimental scenario. We finally apply the evolution equations to re-analyze the Stern\&Gerlach experiment and to show how to manipulate spin by employing constant electric fields.

description: We present our experiments on refractometric sensing with ultrahigh-Q, crystalline, birefringent magnesium fluoride (MgF$_2$) whispering gallery mode resonators. The difference to fused silica which is most commonly used for sensing experiments is the small refractive index of MgF$_2$ which is very close to that of water. Compared to fused silica this leads to more than 50% longer evanescent fields and a 4.25 times larger sensitivity. Moreover the birefringence amplifies the sensitivity difference between TM and TE type modes which will enhance sensing experiments based on difference frequency measurements. We estimate the performance of our resonators and compare them with fused silica theoretically and present experimental data showing the interferometrically measured evanescent decay and the sensitivity of mm-sized MgF$_2$ whispering gallery mode resonators immersed in water. They show reasonable agreement with the developed theory. Furthermore, we observe stable Q factors in water well above $1 \times 10^8$.

description: The fact that quantum gravity does not admit an invariant vacuum state has far-reaching consequences for all physics. It points out that space could not be empty, and we return to the notion of an aether. Such a concept requires a preferred reference frame for describing universe expansion and black holes. Here, we intend to find a reference system or class of metrics that could be attributed to ``aether''. We discuss a vacuum and quantum gravity from three essential viewpoints: universe expansion, black hole existence, and quantum decoherence.

description: Graphene/hBN heterostructures can be considered as one of the basic building blocks for the next-generation optoelectronics mostly owing to the record-high electron mobilities. However, currently, the studies of the intrinsic optical properties of graphene are limited to the standard substrates (SiO2/Si, glass, quartz) despite the growing interest in graphene/hBN heterostructures. This can be attributed to a challenging task of the determination of hBN's strongly anisotropic dielectric tensor in the total optical response. In this study, we overcome this issue through imaging spectroscopic ellipsometry utilizing simultaneous analysis of hBN's optical response with and without graphene monolayers. Our technique allowed us to retrieve the optical constants of graphene from graphene/hBN heterostructures in a broad spectral range of 250-950 nm. Our results suggest that graphene's absorption on hBN may exceed the one of graphene on SiO2/Si by about 60 %.

description: High levels of horizontal magnetic flux have been reported in the quiet-Sun internetwork, often based on Stokes profile inversions. Here we introduce a new method for deducing the inclination of magnetic elements and use it to test magnetic field inclinations from inversions. We determine accurate positions of a set of small, bright magnetic elements in high spatial resolution images sampling different photospheric heights obtained by the Sunrise balloon-borne solar observatory. Together with estimates of the formation heights of the employed spectral bands, these provide us with the inclinations of the magnetic features. We also compute the magnetic inclination angle of the same magnetic features from the inversion of simultaneously recorded Stokes parameters. Our new, geometric method returns nearly vertical fields (average inclination of around 14 deg with a relatively narrow distribution having a standard deviation of 6 deg). In strong contrast to this, the traditionally used inversions give almost horizontal fields (average inclination of 75+-8 deg) for the same small magnetic features, whose linearly polarised Stokes profiles are adversely affected by noise. The almost vertical field of bright magnetic features from our geometric method is clearly incompatible with the nearly horizontal magnetic fields obtained from the inversions. This indicates that the amount of magnetic flux in horizontal fields deduced from inversions is overestimated in the presence of weak Stokes signals, in particular if Stokes Q and U are close to or under the noise level. By combining the proposed method with inversions we are not just improving the inclination, but also the field strength. This technique allows us to analyse features that are not reliably treated by inversions, thus greatly extending our capability to study the complete magnetic field of the quiet Sun.

description: This research paper explores the phonetic characteristics and usage of English in the Sri Lankan context, focusing on how local linguistic and cultural influences shape English pronunciation and speech patterns. Sri Lanka, with its diverse linguistic background, including Sinhala and Tamil as the primary languages, has developed a distinct variety of English influenced by these languages.

The study aims to analyze the unique phonetic features, such as vowel and consonant sounds, stress patterns, and intonation, that differentiate Sri Lankan English from other global varieties. It also examines how these phonetic features impact communication, education, and social identity within Sri Lankan society. By gathering data from native Sri Lankan English speakers and comparing it to standard British English, the research highlights the interaction between local languages and English in everyday use, exploring both challenges and opportunities in English language teaching and learning in Sri Lanka.

This study contributes to a better understanding of the evolving nature of English in multilingual societies, particularly in post-colonial contexts like Sri Lanka, where English continues to play a crucial role in education, business, and global communication.

description: The structure of molecular clouds can be characterized with the probability distribution function (PDF) of the mass surface density. In particular, the properties of the distribution can reveal the nature of the turbulence and star formation present inside the molecular cloud. In this paper, we explore how these structural characteristics evolve with time and also how they relate to various cloud properties as measured from a sample of synthetic column density maps of molecular clouds. We find that, as a cloud evolves, the peak of its column density PDF will shift to surface densities below the observational threshold for detection, resulting in an underlying lognormal distribution which has been effectively lost at late times. Our results explain why certain observations of actively star-forming, dynamically older clouds, such as the Orion molecular cloud, do not appear to have any evidence of a lognormal distribution in their column density PDFs. We also study the evolution of the slope and deviation point of the power-law tails for our sample of simulated clouds and show that both properties trend towards constant values, thus linking the column density structure of the molecular cloud to the surface density threshold for star formation.

description: The transition angles are defined to describe the vowel-to-vowel transitions in the acoustic space of the Spectral Subband Centroids, and the findings show that they are similar among speakers and speaking rates. In this paper, we propose to investigate the usage of polar coordinates in favor of angles to describe a speech signal by characterizing its acoustic trajectory and using them in Automatic Speech Recognition. According to the experimental results evaluated on the BRAF100 dataset, the polar coordinates achieved significantly higher accuracy than the angles in the mixed and cross-gender speech recognitions, demonstrating that these representations are superior at defining the acoustic trajectory of the speech signal. Furthermore, the accuracy was significantly improved when they were utilized with their first and second-order derivatives ($Δ$, $Δ$$Δ$), especially in cross-female recognition. However, the results showed they were not much more gender-independent than the conventional Mel-frequency Cepstral Coefficients (MFCCs).

description: Intensity mapping with the redshifted 21-cm line is an emerging tool in cosmology. Drift scan observations, where the antennas are fixed to the ground and the telescope's pointing center (PC) changes continuously on the sky due to earth's rotation, provide broad sky coverage and sustained instrumental stability needed for 21-cm intensity mapping. Here we present the Tracking Tapered Grided Estimator (TTGE) to quantify the power spectrum of the sky signal estimated directly from the visibilities measured in drift scan radio interferometric observations. The TTGE uses the data from the different PC to estimate the power spectrum of the signal from a small angular region located around a fixed tracking center (TC). The size of this angular region is decided by a suitably chosen tapering window function which serves to reduce the foreground contamination from bright sources located at large angles from the TC. It is possible to cover the angular footprint of the drift scan observations using multiple TC, and combine the estimated power spectra to increase the signal to noise ratio. Here we have validated the TTGE using simulations of $154 \, {\rm MHz}$ MWA drift scan observations. We show that the TTGE can recover the input model angular power spectrum $C_{\ell}$ within $20 \%$ accuracy over the $\ell$ range $40 < \ell < 700$.

description: Проанализированы существующие научные исследования в области разрушения зерна. Для увеличения продуктивности сельскохозяйственных животных необходимо включать в их рацион высоко-белковые корма. Горох является отличным и доступным источником протеина. Улучшить качество пе-ревариваемости гороха можно с помощью различных способов его обработки, наиболее приемлемым из них является измельчение, имеющее в своей основе способ разрушения отраженный удар. Рассмотрены различные подходы к определению скорости удара рабочим органом измельчителя, проведен опыт по определению кинетической энергии, необходимой для разрушения зерна гороха «Алтайский усатый», воз-делываемого в Костанайской области, и на основании полученных данных получены зависимости часто-ты оборотов диска измельчителя от степени измельчения материала и диаметра наружного ротора. В результате проведения испытаний было установлено, что оптимальная скорость удара ударно-центро-бежной дробилки (УЦД) должна быть не менее 25,56 м/с при наружном диаметре ротора 0,4 м и с задан-ной степенью измельчения 1,31 мм. Число оборотов лопаток должно быть не менее 962,9 с-1.The grain destruction field’s existing research are analyzed.

description: Crypto-coins (also known as cryptocurrencies) are tradable digital assets. Notable examples include Bitcoin, Ether and Litecoin. Ownerships of cryptocoins are registered on distributed ledgers (i.e., blockchains). Secure encryption techniques guarantee the security of the transactions (transfers of coins across owners), registered into the ledger. Cryptocoins are exchanged for specific trading prices. While history has shown the extreme volatility of such trading prices across all different sets of crypto-assets, it remains unclear what and if there are tight relations between the trading prices of different cryptocoins. Major coin exchanges (i.e., Coinbase) provide trend correlation indicators to coin owners, suggesting possible acquisitions or sells. However, these correlations remain largely unvalidated. In this paper, we shed lights on the trend correlations across a large variety of cryptocoins, by investigating their coin-price correlation trends over a period of two years. Our experimental results suggest strong correlation patterns between main coins (Ethereum, Bitcoin) and alt-coins. We believe our study can support forecasting techniques for time-series modeling in the context of crypto-coins. We release our dataset and code to reproduce our analysis to the research community.

description: Size-dependence of plastic flow is studied by discrete dislocation dynamical simulation of systems with various numbers of interacting linear edge dislocations while the stress is slowly increased. Regions between avalanches in the individual stress curves as functions of the plastic strain were found nearly linear and reversible, where the plastic deformation obeys an effective equation of motion with a nearly linear force. For small plastic deformation, the means of the stress-strain curves are power law over two decades. Here and for somewhat larger plastic deformations, the mean stress-strain curves converge for larger sizes, while their variances shrink, both indicating the existence of a thermodynamical limit. The converging averages decrease with increasing size, in accordance with size-effects from experiments. For large plastic deformations, where steady flow sets in, thermodynamical limit was not realized in this model system.

description: We apply the variational approach to solitons in highly nonlocal nonlinear media in $D=1,2,3$ dimensions. We compare results obtained by the variational approach with those obtained in the accessible soliton approximation, by considering the same system of equations in the same spatial region and under the same boundary conditions. To assess the accuracy of these approximations, we also compare them with the numerical solution of the equations. We discover that the variational highly nonlocal approximation provides more accurate results and as such is more appropriate solution than the accessible soliton approximation.

title: Lives lived ‘at such a distance’: How distance shaped masculinity and femininity in the British Atlantic, c.1660-1760
Creators: name: Brennan, Harry A.J.
Publisher: name: University of Glasgow
Year: 2022

description: This thesis explores the role distance played in shaping British masculinity and femininity in the early modern British Atlantic world. Focusing on gender as a foundation of individual identity, this research outlines the powerful effects of Atlantic crossings, maritime trade networks, and encounters with new landscapes and nations. It covers a century of colonial expansion across North America and the Caribbean, from the Restoration to the Seven Years’ War. Building on an earlier study of Anglo-Virginian planter William Byrd II (1674-1744), this thesis uses a series of interconnected individuals as case studies. It explores these individuals’ experiences through five key dynamics: credit, seafaring, communication and emotions, settler-Indigenous encounters, and race. This approach builds on prosopography, the ‘serial microhistory’ approach developed by Kristen Block, and Atlantic history more widely. Responding to historiographical questions posed by Susan Amussen, Allyson Poska, and Julie Hardwick, it draws on diverse fields of study. These include geography, maritime history, the spatial turn, studies of emotion, intersectional analysis, Indigenous scholarship, and gender studies. This thesis explores how distance and interaction created ‘Atlantic masculinities’ in Britain and its colonies. Furthermore, it asks if complementary or divergent ‘Atlantic femininities’ can be found in this period. In summary, this research shows how the ‘New World’ produced new identities over a century of British imperial expansion.

description: We study angular-momentum couplings in $^{87}$Rb$_2$ Rydberg molecules formed between Rydberg and 5S$_{1/2}$ ground-state atoms. We use a Fermi model that includes S-wave and P-wave singlet and triplet scattering of the Rydberg electron with the 5S$_{1/2}$ atom, along with the fine structure coupling of the Rydberg atom and hyperfine structure coupling of the 5S$_{1/2}$ atom. We discuss the effects of these couplings on the adiabatic molecular potentials. We obtain bound-state energies, lifetimes, and electric and magnetic dipole moments for the vibrational ground states of the $^{87}$Rb$(n$D$+5$S$_{1/2})$ molecules in all adiabatic potentials, with fine and hyperfine structure included. We also study the effect of the hyperfine structure on the deep $^3$S-wave- and $^3$P-wave-dominated adiabatic molecular potentials, which support high-$\ell$ $^{87}$Rb$_2$ Rydberg molecules.
A semiempirical approach to low-energy cosmic ray propagation in the diffuse interstellar medium
Creators: name: Franceschi, Riccardo
name: Shore, Steven Neil
Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We investigate the ionization of the diffuse interstellar medium by cosmic rays by modeling their propagation along the wandering magnetic fields using a Monte Carlo method. We study how low-energy cosmic rays propagate in turbulent, translucent molecular clouds, and how they regulate the ionization and both lose and gain energy from the medium. As a test case, we use high spatial resolution (0.03 pc) CO maps of a well-studied high latitude translucent cloud, MBM 3, to model turbulence. The propagation problem is solved with a modified Monte Carlo procedure that includes trapping, energization, and ionization losses. In a homogeneous medium, trapping and re-energization do not produce a significant effect. In a nonuniform medium, particles can be trapped for a long time inside the cloud. This modifies the cosmic ray distribution due to stochastic acceleration at the highest energies (about 100 MeV). At lower energies, the re-energization is too weak to produce an appreciable effect. The change in the energy distribution does not significantly affect the ionization losses, so ionization changes are due to trapping effects.

description: Racah matrices of quantum algebras are of great interest at present time. These matrices have a relation with $\mathcal{R}$-matrices, which are much simpler than the Racah matrices themselves. This relation is known as the eigenvalue conjecture. In this paper we study symmetries of Racah matrices which follow from the eigenvalue conjecture for multistrand braids.

description: The nonequilibrium activity taking place in a living cell can be monitored with a tracer embedded in the medium. While microrheology experiments based on optical manipulation of such probes have become increasingly standard, we put forward a number of experiments with alternative protocols that, we claim, will provide new insight into the energetics of active fluctuations. These are based on either performing thermodynamic--like cycles in control-parameter space, or on determining response to external perturbations of the confining trap beyond simple translation. We illustrate our proposals on an active itinerant Brownian oscillator modeling the dynamics of a probe embedded in a living medium.

simulation

description: Here, we report on our approach to establish a durable, rigid connection between the Aquarius beamline at synchrotron source Bessy II and its digital counterpart build in the simulation software Ray-UI [1]. While simulations play a crucial role in the instrument design as a digital precursor of the real-world object and contain a comprehensive description of the setup, usually the digital representation is neglected once the real instrument is fully commissioned. To preserve the symbiosis of simulated and real-world instrument beyond commissioning and approach the digital twin concept we combine the two worlds at the NeXus file level [2]. For this purpose, the instrument section of the NeXus file is enriched by detailed simulation parameters where the current state of the instrument is reflected by including real motor positions, e. g. to incorporate the actual aperture of a slit system. As a result, on one hand, the enriched instrument description increases the reusability of experimental data in sense of the FAIR principles [3] and, on the other hand, allows to perform simulations of a measurement from the NeXus file, ready to be exploited by machine-learning techniques, e. g. for predictive maintenance.

description: Beside the environmental and energetic issues, carbon dioxide can be considered as a resource. Many chemical transformations based on CO2 as C-1 building block have been developed. The coupling reaction of epoxides with CO2 is one of the most attractive. An overview on the state of the art for metal-mediated process is provided. Particular enphasis is given to the iron-based systems, because it is an ideal candidate for the development of environmental and economic sustainable catalytic systems. It is the aim of this thesis to investigate the application of sulphur containing ligand based iron complexes, starting from the encouraging results reported by the research group of Capacchione in the case of the bis-thioether-tri-phenolate ligand based bimetallic Fe(III) complex.3 The synthesis and the complete characterization of five new thioether triphenolate ligands (L2-6), and of the corresponding bimetallic iron(III) complexes (2-6) is reported...

description: Understanding the role of higher derivatives is probably one of the most relevant questions in quantum gravity theory. Already at the semiclassical level, when gravity is a classical background for quantum matter fields, the action of gravity should include fourth derivative terms to provide renormalizability in the vacuum sector. The same situation holds in the quantum theory of metric. At the same time, including the fourth derivative terms means the presence of massive ghosts, which are gauge-independent massive states with negative kinetic energy. At both classical and quantum level such ghosts violate stability and hence the theory becomes inconsistent. Several approaches to solve this contradiction were invented and we are proposing one more, which looks simpler than those what were considered before. We explore the dynamics of the gravitational waves on the background of classical solutions and give certain arguments that massive ghosts produce instability only when they are present as physical particles. At least on the cosmological background one can observe that if the initial frequency of the metric perturbations is much smaller than the mass of the ghost, no instabilities are present.

Effect of Strong Disorder on 3-Dimensional Chiral Topological Insulators: Phase Diagrams, Maps of the Bulk Invariant and Existence of Topological Extended Bulk States

description: The effect of strong disorder on chiral-symmetric 3-dimensional lattice models is investigated via analytical and numerical methods. The phase diagrams of the models are computed using the non-commutative winding number, as functions of disorder strength and model's parameters. The localized/delocalized characteristic of the quantum states is probed with level statistics analysis. Our study re-confirms the accurate quantization of the non-commutative winding number in the presence of strong disorder, and its effectiveness as a numerical tool. Extended bulk states are detected above and below the Fermi level, which are observed to undergo the so called "levitation and pair annihilation" process when the system is driven through a topological transition. This suggests that the bulk invariant is carried by these extended states, in stark contrast with the 1-dimensional case where the extended states are completely absent and the bulk invariant is carried by the localized states.
