description: One main goal of geodetic deformation monitoring and analysis is minimizing the risk of unexpected collapses of artificial objects and geologic hazards. Nowadays, the methodology in applied geodesy and mathematically founded decisions are usually based on probabilities and significance levels but not on the risk (consequences or costs) itself. In this study, a new concept which is based on the utility theory is introduced to the current methodology. It allows the consideration of consequences or costs for geodetic decision making in order to meet the real requirements. In this case, possible decisions are evaluated with cost functions for type I and II errors. Finally, the decision leading to the minimum costs or consequences is chosen as the most beneficial one. This procedure allows also identifying the most beneficial additional measurements to reduce the risk of an individual monitoring process. In the last part, the theoretical concept is applied to an example in slope monitoring.

description: The halo structure originated in nuclear physics but is now encountered more widely. It appears in loosely bound, clustered systems where the spatial extension of the system is significantly larger than that of the binding potentials. A review is given on our current understanding of these structures, with an emphasis on how the structures evolve as more cluster components are added, and on the experimental situation concerning halo states in light nuclei.

description: Electromagnetic stimuli of spin crossover compounds restricted to UV-vis light irradiation for many years could be recently extended to X-ray excitation. This review covers a large variety of light-induced effects, as well as recent analogues stimulated by X-ray irradiation which have not yet been reviewed. The focus is also on multistable multinuclear spin crossover compounds which are the subject of lively discussions within the spin crossover community. Their spin transition often occurs incompletely and with different switching mechanisms. In this review, we recall a predicted sequential switching induced thermally as well as a concerted stimulation mechanism by light irradiation for these interesting multifunctional materials.
Correlation distances in social networks

description: In this work, we explore degree assortativity in complex networks, and extend its usual definition beyond that of nearest neighbours. We apply this definition to model networks, and describe a rewiring algorithm that induces assortativity. We compare these results to real networks. Social networks in particular tend to be assortatively mixed by degree in contrast to many other types of complex networks. However, we show here that these positive correlations diminish after one step and in most of the empirical networks analysed. Properties besides degree support this, such as the number of papers in scientific coauthorship networks, with no correlations beyond nearest neighbours. Beyond next-nearest neighbours we also observe a disassortative tendency for nodes three steps away indicating that nodes at that distance are more likely different than similar

The experimental results are compared to simulated images in order to verify possible experimental artefacts. In this work we show that for this type of nano-objects, a residual tilt of the specimen below 15 mrad, away from the crystallographic zone axis does not impair the interpretation of the experimental images.

description: We theoretically investigate light matter interactions for chiral molecules in the presence of non-chiral nanoantennas. Isotropic nanostructures supporting optical-frequency electric or magnetic dipoles are sufficient to locally enhance the excitation of a molecule's chiral polarizability and thus its circular dichroism spectrum. However, simultaneous electric and magnetic dipoles are necessary to achieve a net, spatially-averaged enhancement. Our contribution provides a theoretical framework to understand chiral light-matter interactions at the nanoscale and sets the necessary and sufficient conditions to enhance circular dichroism spectroscopy in the presence of nanoantennas. The results may lead to new, field-enhanced, chiral spectroscopic techniques.

We report on a complete characterization of their structural properties via synchrotron nanoprobe as well as laboratory single-crystal diffraction techniques. This investigation allowed us to fully disclose the growth mechanism, which leads to the formation of curved whiskers. The superconducting properties are evaluated in comparison with the straight counterpart, revealing a strong functional analogy and confirming their potential applicability in superconducting electronic devices.

description: It is shown that the joint distribution of energy eigenvalues for systems with a varying degree of nonintegrability which has been obtained dynamically by T. Yukawa [Phys. Rev. Lett. 54, 1883 (1985)] can also be deduced by putting his equations of motion in the form of stochastic differential equations. We obtain an interpolation formula for the nearest-neighbor-spacing distribution as a smooth one-parameter family of density functions Pλ(S), 0≤λ<∞. This distribution retains a nonanalytic nature near λ→0; when λ=0 it agrees with the Poissonian distribution but whenever λ≠0 it is proportional to S for small S, as predicted by M. Robnik [J. Phys. A 20, L495 (1987)]. A considerable improvement on the agreement between the energy-level histogram in a real system (hydrogen in a magnetic field) and theoretical formulas which have been studied by Wintgen and Friedrich [Phys. Rev. A 35, 1464 (1987)] is demonstrated.

description: In this paper, we present photometry for young star clusters in M31, which are selected from Caldwell et al. These star clusters have been observed as part of the Beijing--Arizona--Taiwan--Connecticut (BATC) Multicolor Sky Survey from 1995 February to 2008 March. The BATC images including these star clusters are taken with 15 intermediate-band filters covering 3000--10000 Å. Combined with photometry in the {\sl GALEX} far- and near-ultraviolet, broad-band $UBVRI$, SDSS $ugriz$, and infrared $JHK_{\rm s}$ of Two Micron All Sky Survey, we obtain their accurate spectral energy distributions (SEDs) from 1538-20000 Å. We derive these star clusters' ages and masses by comparing their SEDs with stellar population synthesis models. Our results are in good agreement with previous determinations. The mean value of age and mass of young clusters ($<2$ Gyr) is about 385 Myr and $2\times 10^4 {M_\odot}$, respectively. There are two distinct peaks in the age distribution, a highest peak at age $\sim$ 60 Myr and a secondary peak around 250 Myr, while the mass distribution shows a single peak around $10^4 {M_\odot}$. A few young star clusters have two-body relaxation times greater than their ages, indicating that those clusters have not been well dynamically relaxed and therefore have not established the thermal equilibrium. There are several regions showing aggregations of young star clusters around the 10 kpc ring and the outer ring, indicating that the distribution of the young star clusters is well correlated with M31's star-forming regions. The young massive star clusters (age $\leq 100$ Myr and mass $\geq 10^4 {M_\odot}$) show apparent concentration around the ring splitting region, suggesting a recent passage of a satellite galaxy (M32) through M31 disk.

description: The masses of 68 supermassive black holes (SMBHs) in nearby (z<0.15) active galactic nuclei (AGNs) detected by the INTEGRAL observatory in the hard X-ray energy band (17-60 keV) outside the Galactic plane (|b| > 5 degrees) have been estimated. Well-known relations between the SMBH mass and (1) the infrared luminosity of the stellar bulge (from 2MASS data) and (2) the characteristics of broad emission lines (from RTT-150 data) have been used. A comparison with the more accurate SMBH mass estimates obtained by the reverberation-mapping technique and from direct dynamical measurements is also made for several objects. The SMBH masses derived from the correlation with the bulge luminosity turn out to be systematically higher than the estimates made by other methods. The ratio of the bolometric luminosity to the critical Eddington luminosity has been found for all AGNs. It ranges from 1 to 100% for the overwhelming majority of objects.

A high-order, purely frequency based harmonic balance formulation for continuation of periodic solutions: The case of non-polynomial nonlinearities

description: In this paper, we extend the method proposed by Cochelin and Vergez [A high order purely frequency-based harmonic balance formulation for continuation of periodic solutions, Journal of Sound and Vibration, 324 (2009) 243-262] to the case of non-polynomial nonlinearities. This extension allows for the computation of branches of periodic solutions of a broader class of nonlinear dynamical systems. The principle remains to transform the original ODE system into an extended polynomial quadratic system for an easy application of the harmonic balance method (HBM). The transformation of non-polynomial terms is based on the differentiation of state variables with respect to the time variable, shifting the nonlinear non-polynomial nonlinearity to a time-independent initial condition equation, not concerned with the HBM. The continuation of the resulting algebraic system is here performed by the asymptotic numerical method (high order Taylor series representation of the solution branch) using a further differentiation of the non-polynomial algebraic equation with respect to the path parameter. A one dof vibro-impact system is used to illustrate how an exponential nonlinearity is handled, showing that the method works at very high order, 1000 in that case. Various kinds of nonlinear functions are also treated, and finally the nonlinear free pendulum is addressed, showing that very accurate periodic solutions can be computed with the proposed method.
Mineral bridges in nacre revisited

description: We confirm with high-resolution techniques the existence of mineral bridges between superposed nacre tablets. In the towered nacre of both gastropods and the cephalopod Nautilus there are large bridges aligned along the tower axes, corresponding to gaps (150-200 nm) in the interlamellar membranes. Gaps are produced by the interaction of the nascent tablets with a surface membrane that covers the nacre compartment. In the terraced nacre of bivalves bridges associated with elongated gaps in the interlamellar membrane (> 100 nm) have mainly been found at or close to the edges of superposed parental tablets. To explain this placement, we hypothesize that the interlamellar membrane breaks due to differences in osmotic pressure across it when the interlamellar space below becomes reduced at an advanced stage of calcification. In no cases are the minor connections between superimposed tablets (< 60 nm), earlier reported to be mineral bridges, found to be such.

description: Most of the available modeling and simulation tools for performance analysis do not support model optimization sufficiently. One reason for this unsatisfactory situation is the lack of universally applicable and adaptive optimization strategies. Another reason is that modeling and simulation tools usually have a monolithic software design, which is difficult to extend with experimentation functionality. Such functionality has gained on importance in recent years due to the capability of an automatic extraction of valuable information and knowledge out of complex models. One of the most important experimentation goals is to find model parameter settings, which produce optimal model behavior. In this paper, we elaborate on the design of a powerful optimization component and its integration into existing modeling and simulation tools. For that purpose, we propose a hybrid integration approach being a combination of loose document-based and tight invocation-based integration concepts. Beside the integration concept for the optimization component, we also give a detailed insight into the applied optimization strategies. © 2006, IGI Global. All rights reserved.
A Novel Service Oriented Model for Query Identification and Solution Development using Semantic Web and Multi Agent System

Subjects: subject: Multiagent Systems (cs.MA)

description: In this paper, we propose to develop service model architecture by merging multi-agentsystems and semantic web technology. The proposed architecture works in two stages namely, Query Identification and Solution Development. A person referred to as customer will submit the problem details or requirements which will be referred to as a query. Anyone who can provide a service will need to register with the registrar module of the architecture. Services can be anything ranging from expert consultancy in the field of agriculture to academic research, from selling products to manufacturing goods, from medical help to legal issues or even providing logistics. Query submitted by customer is first parsed and then iteratively understood with the help of domain experts and the customer to get a precise set of properties. Query thus identified will be solved again with the help of intelligent agent systems which will search the semantic web for all those who can find or provide a solution. A workable solution workflow is created and then depending on the requirements, using the techniques of negotiation or auctioning, solution is implemented to complete the service for customer. This part is termed as solution development. In this service oriented architecture, we first try to analyze the complex set of user requirements then try to provide best possible solution in an optimized way by combining better information searches through semantic web and better workflow provisioning using multi agent systems.

description: In this paper we present the evolution of a collaborative courseware generating system that is featured by XML-based course structure representation, JSP-based dynamic courseware presentation, and WebDAV-based collaborative courseware authoring. While the first system implementation employs a proprietary design using a self-defined XML DTD to represent the course structure, the second and the third system implementation take an open-standard-oriented approach, which are respectively SCORM 1.1 and SCORM 1.2 conformant. In the latter two implementations, all learning resources contained in an existing Java course are re-designed according to the SCORM 1.1 and SCORM 1.2 Content Model and further annotated with corresponding SCORM metadata. In addition, the course structure is re-constructed utilizing SCORM 1.1 Content Structure Format and SCORM 1.2 Content Packaging Specification. The evolution of the collaborative courseware generating system is motivated by our efforts to improve the reusability and interoperability of learning resources. © 2003, IGI Global.

FAIR data and Marine Robotics
Creators: name: Ferretti, Roberta
Publisher: name: Zenodo
Year: 2023

description: A solid understanding of the ocean functioning is now more important than ever. With the advent of the UN Decade of Ocean Science for Sustainable Development and the boost of marine technology, now we have access to groundbreaking observations. Novel robotics can shed light on unexplored marine areas and unlock the observation of pristine environments leaving no trace behind. Pioneering ocean robots are filling the observational gap in marine sciences by collecting a growing amount of original data. These innovative, non-standard robotic platforms, including autonomous underwater vehicles (AUVs) and surface vehicles (ASVs), are developed to overcome environmental constraints or meet specific requirements, such as working in critical polar environments, transitional waters, and areas characterized by very shallow water conditions, where conventional data collection techniques are often ineffective or non-usable. With the increasing expansion of marine robotics applications and the growing number of research groups collecting vast amounts of data, the implementation of FAIR principles becomes of fundamental importance, especially for datasets encompassing both environmental and robotic data and metadata. Implementing FAIR principles in managing these data will facilitate greater accessibility and sharing among experts, enhancing cooperation and collaboration in the field of marine robotics, contributing to mission safety improvement, ensuring greater accuracy and reliability of data and results, which constitute a crucial contribution to global marine research and conservation efforts.
The marine robotics group at CNR INM in Genoa has decades of experience in developing highly modular and reconfigurable autonomous robotic platforms that enable access and monitoring in critical environments and in their use during experimental data acquisition campaigns. Moreover, the increasing use of robotic platforms as technological enablers for innovative services addressed to diverse stakeholders, including research groups as well as SMEs, authorities and administrations, and the public community and citizens, is leading to the recording of big volumes of data. To harness their potential effectively, a change of perspective is underway within the CNR INM robotics group, emphasizing the centrality of the data and their management through the application of FAIR principles.
This contribution will outline the efforts of the CNR INM group in developing and implementing a framework for the acquisition and management of environmental and robotic datasets, enabling the generation of integrated "FAIR by default" data. The purpose of this work, which recognizes the centrality of data through the implementation of the FAIR principles, is to facilitate the storage and long-term preservation, sharing, and reuse of these datasets. This will elevate both their scientific value and the potential to formulate more sustainable management strategies for the marine environment, fundamental for the health of the planet and of the well being of the people.

description: In this paper the transonic flow field in a vaned diffuser of a centrifugal compressor has been studied. Different geometries of the diffuser blades have been considered. Particularly with respect to the pressure field it is important to understand their influence on the development of the shock waves. For this problem a centrifugal compressor with high pressure ratio per stage has been examined. It is assumed that the impeller speed is so large that the flow may become transonic at the impeller exit. To calculate flows with shocks a time-marching method is used for solving the two-dimensional Euler equations in a conservative form. A MacCormack's second order difference scheme is applied. There are two important points which have been studied in this paper. Firstly the geometry of the blades as far as the thickness distribution is concerned is kept unchanged and only the stagger angle has been altered. The performance maps of these diffusers and their effect on the whole machine will be discussed. Secondly the results which have been obtained by using vanes with different thickness distributions will be presented. Mean values of the quantities used for the performance map will be shown. Wall pressure distributions as well as fields of isobars and of constant Mach numbers will be demonstrated to provide a better understanding of the pressure recovery in centrifugal compressor diffusers. © Martinus Nijhoff Publishers, Dordrecht and Freund Publishing House

description: The Conservation of Energy plays a pivotal part in the development of the physical sciences. With the growth of computation and the study of other discrete token based systems such as the genome, it is useful to ask if there are conservation principles which apply to such systems and what kind of functional behaviour they imply for such systems. Here I propose that the Conservation of Hartley-Shannon Information plays the same over-arching role in discrete token based systems as the Conservation of Energy does in physical systems. I will go on to prove that this implies power-law behaviour in component sizes in software systems no matter what they do or how they were built, and also implies the constancy of average gene length in biological systems as reported for example by Lin Xu et al (10.1093/molbev/msk019). These propositions are supported by very large amounts of experimental data extending the first presentation of these ideas in Hatton (2011, IFIP / SIAM / NIST Working Conference on Uncertainty Quantification in Scientific Computing, Boulder, August 2011).

description: Intelligible communication between different groups and classes in a society is a precondition for the existence of a ‘public’ in the classical, political sense of that term. The importance of such communication for a democratic policy was highlighted in the sixties when both reformers and revolutionaries generally failed in their efforts to educate or politicize tow-income groups. In this essay we discuss sociolinguistic theories as they bear on this question. First, we critically assess theories that bring the methods of linguistics to micro-sociological studies of speech behaviour Then we relate this work to the rich ethnographic literature on low-income culture, placing this amalgam of linguistics and ethnography in a larger political economic context We conclude by suggesting some moral and political implications of such a project. © 1982, Sage Publications.

Investigating the Expression of D-type Cyclins in Diffuse Large B-cell Lymphoma (DLBCL)
Creators: name: Bowden, Daniel G.
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Diffuse Large B-cell Lymphoma (DLBCL) is a highly aggressive and highly heterogenous cancer which varies dramatically in response to treatment. Attempts to classify DLBCL have identified two distinct subgroups, an Activated B-cell like (ABC-DLBCL) and a Germinal centre B-cell line (GBC-DLBCL), based on gene expression profiling. Amongst the genes used to distinguish these two subgroups is Cyclin D2. Best known for their role in the regulating cell cycle, the three D-type cyclins, Cyclin D1, D2 and D3 share a high sequence homology (50-60%) and are often considered redundant. A CRISPR study performed by Phelan et al in 2018 suggested that ABC-DLBCL were dependent on the expression of Cyclin D2, despite co-expressing Cyclin D3, whilst GCB-DLBCL were dependent on Cyclin D3. How or why ABC-DLBCL are dependent on Cyclin D2 expression is unclear. This project therefore aimed to investigate the signalling pathways that are involved in regulating Cyclin D2 expression in ABC-DLBCL. During this study, we identify the existence of a previously undescribed Cyclin D2 Negative subgroup of ABC-DLBCL. RNA-seq analysis indicates that this subgroup has significantly lower IL10-STAT3 signalling than its Cyclin D2 positive counterpart. These findings were confirmed using publicly available Sc-RNA seq data, with further analysis of patient bulk RNA-seq suggesting the levels of Cyclin D2 and Cyclin D3 could be used as an effective prognostic marker for progression free survival in DLBCL. Preliminary studies investigating the subcellular localisation of D-type Cyclins found that Cyclin D3 appears to form distinct foci, the function of which are currently unknown. As part of this study, preliminary steps have been taken to developed a proteomics pipeline that could be used to compare to the binding partners of Cyclin D2 and Cyclin D3 in DLBCL in an attempt to elucidate how these distinct functions are performed. Taken together, these data generated as part of this study highlights the heterogeneity exhibited within the ABC-DLBCL subgroup, and indicate that a greater understanding of Cyclin D expression profiles, and associated pathways, could prove invaluable for treatment.

In the hard x-ray regime, achieving large dispersion rates is a challenge. Here we show that multi-crystal, multi-Bragg-reflection arrangements feature cumulative angular dispersion rates almost two orders of magnitude larger than those attainable with a single Bragg reflection. As a result, the multi-crystal arrangements become potential dispersing elements of hard x-ray spectrographs. The hard x-ray spectrograph principles are demonstrated by imaging a spectrum of photons with a record high resolution of $ΔE \simeq 90 μ$eV in hard x-ray regime, using multi-crystal optics as dispersing element. The spectrographs can boost research using inelastic ultra-high-resolution x-ray spectroscopies with synchrotrons and seeded XFELs.

description: For the analysis of dose-response relationship under the assumption of ordered alternatives several global trend tests are available. Furthermore, there are multiple test procedures which can identify doses as effective or even as minimally effective. In this paper it is shown that the principles of multiple comparisons and interim analyses can be combined inflexible and adaptive strategies for dose-response analyses; these procedures control the experimentwise error rate. © 2000, Drug Information Association.

description: We investigate the effect of spin-orbit coupling on the band structure of graphene-based two-dimensional Dirac fermion gases in the quantum Hall regime. Taking monolayer graphene as our first candidate, we show that a quantum phase transition between two distinct topological states -- the quantum Hall and the quantum spin Hall phases -- can be driven by simply tuning the Fermi level with a gate voltage. This transition is characterized by the existence of a chiral spin-polarized edge state propagating along the interface separating the two topological phases. We then apply our analysis to the more difficult case of bilayer graphene. Unlike in monolayer graphene, spin-orbit coupling by itself has indeed been predicted to be unsuccessful in driving bilayer graphene into a topological phase, due to the existence of an even number of pairs of spin-polarized edge states. While we show that this remains the case in the quantum Hall regime, we point out that by additionally breaking the layer inversion symmetry, a non-trivial quantum spin Hall phase can re-emerge in bilayer graphene at low energy. We consider two different symmetry-breaking mechanisms: inducing spin-orbit coupling only in the upper layer, and applying a perpendicular electric field. In both cases, the presence at low energy of an odd number of pairs of edge states can be driven by an exchange field. The related situation in trilayer graphene is also discussed.

description: Due to their nonlocality, qubits nested in Majorana bound states may be the key to realize decoherence-free quantum computation. Majorana bound states could be achieved at the ends of a one-dimensional topological superconductor. However, when the bound states couple directly to electron reservoirs their nonlocal correlation is quenched by local Andreev reflections. Here we propose a scheme to generate nonlocal noise cross correlation between two well-separated quantum dots, mediated by a pair of Majorana bound states. Both positive and negative cross correlations can be obtained by tuning the gate voltages applied to the dots. Within a limited range of finite temperatures, the cross correlation is not suppressed by thermal fluctuations. Furthermore, we show how the local Andreev reflections suppress the noise cross correlation when multiple dot energy levels are coupled to the Majorana bound states. The measurable cross correlation is expected to serve as a sensitive indicator for the generation of Majorana fermions.

description: Multiscale modeling of structures made from shape memory alloys (SMA) is presented. Starting with consideration of a single transformation event at the micro-level and averaging over the representative volume, micromechanically-based macroscopic constitutive equations are derived, which are used in Finite Element Method (FEM) code to model the behaviour of structures. Using the thermodynamic theory of phase transformations (PT) in elastic materials on the micro-level, the macroscopic associated transformation flow rule, the corresponding extremum principle and the nonconcavity of the transformation surface are derived for transformational micromechanisms of inelastic deformation due to phase transformation, twinning and reorientation of martensitic variants. A simple three-dimensional micromechanically-based model for thermoelastic martensitic PT is presented. The model is transformed to the fashion similar to that for J2-plasticity theory. It allows one to modify the FEM for elastoplasticity (including the radial return algorithm for numerical integration of the constitutive equations and calculation of the consistent tangent moduli) in order to model PT in SMA. Some axisymmetric problems for PT in SMA tubes are solved. In particular, PT regularities of a tube assembly with a SMA cylinder element are investigated at different external conditions.

description: Modularity and efficiency are often contradicting requirements, such that programers have to trade one for the other. We analyze this dilemma in the context of programs operating on collections. Performance-critical code using collections need often to be hand-optimized, leading to non-modular, brittle, and redundant code. In principle, this dilemma could be avoided by automatic collection-specific optimizations, such as fusion of collection traversals, usage of indexing, or reordering of filters. Unfortunately, it is not obvious how to encode such optimizations in terms of ordinary collection APIs, because the program operating on the collections is not reified and hence cannot be analyzed. We propose SQuOpt, the Scala Query Optimizer--a deep embedding of the Scala collections API that allows such analyses and optimizations to be defined and executed within Scala, without relying on external tools or compiler extensions. SQuOpt provides the same "look and feel" (syntax and static typing guarantees) as the standard collections API. We evaluate SQuOpt by re-implementing several code analyses of the Findbugs tool using SQuOpt, show average speedups of 12x with a maximum of 12800x and hence demonstrate that SQuOpt can reconcile modularity and efficiency in real-world applications.

description: We present a process-independent technique to consistently combine next-to-leading order parton-level calculations of varying jet multiplicity and parton showers. Double counting is avoided by means of a modified truncated shower scheme. This method preserves both the fixed-order accuracy of the parton-level result and the logarithmic accuracy of the parton shower. We discuss the renormalisation and factorisation scale dependence of the approach and present results from an automated implementation in the Sherpa event generator using the test case of W-boson production at the Large Hadron Collider. We observe a dramatic reduction of theoretical uncertainties compared to existing methods which underlines the predictive power of our novel technique.

description: We report the results of our observations of the 12CO (J=1-0) and 12CO (J=3-2) line emission of 74 major giant molecular clouds (GMCs) within the galactocentric distance of 5.1 kpc in the Local Group galaxy M33. The observations have been conducted as part of the Nobeyama Radio Observatory M33 All-disk survey of Giant Molecular Clouds project (NRO MAGiC). The spatial resolutions are 80 pc for 12CO (J=1-0) and 100 pc for 12CO (J=3-2). We detect 12CO (J=3-2) emission of 65 GMCs successfully. Furthermore, we find that the correlation between the surface density of the star formation rate, which is derived from a linear combination of Halpha and 24um emissions, and the 12CO (J=3-2) integrated intensity still holds at this scale. This result show that the star-forming activity is closely associated with warm and dense gases that are traced with the 12CO (J=3-2) line, even in the scale of GMCs. We also find that the GMCs with a high star-forming activity tend to show a high integrated intensity ratio (R3-2/1-0). Moreover, we also observe a mass-dependent trend of R3-2/1-0 for the GMCs with a low star-forming activity. From these results, we speculate that the R3-2/1-0 values of the GMCs with a low star-forming activity mainly depend on the dense gas fraction and not on the temperature, and therefore, the dense gas fraction increases with the mass of GMCs, at least in the GMCs with a low star-forming activity.

description: Pathologically altered biomechanical properties of the Schlemm’s canal (SC) inner wall microenvironment were recently validated as the cause for increased outflow resistance in ocular hypertensive glaucoma. However, the involvement of specific mechanotransduction pathways in these disease processes is largely unclear. Here, we demonstrate that YAP/TAZ are central regulators of glaucoma-like SC cell dysfunction in response to extracellular matrix stiffening, and that targeted disruption of YAP/TAZ mechanosignaling attenuates SC cell pathobiology and enhances outflow function.
