Role of extracellular matrix and mitochondria related genes in determining cardiac defects in Down syndrome
Creators: name: Cicatiello, Rita
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: Mitochondrial dysfunction, which is consistently observed in Down syndrome (DS), is suspected to worsen mental retardation and congenital cardiopathies in DS subjects, as well as to determine other phenotypic abnormalities, such as Alzheimer's disease, type 2 diabetes, obesity, and hypertrophic cardiopathy.
As the heart is one of the main targets of DS, we have analyzed gene expression of DS fetal hearts demonstrating a global downregulation of nuclear encoded mitochondrial genes (NEMGs) together with the upregulation of clusters of extracellular matrix proteins (ECMs). A mitochondrial dysfunction was found associated with NEMG downregulation in DS fetal fibroblasts (DS-HFFs).
Based on these previous results, this doctorate thesis was aimed:
-	to identify Hsa21 genes responsible for either NEMG downregulation or ECM upregulation;
-	to develop strategies to counteract the negative effects triggered by NEMG dysregulation in DS;
-	to investigate how NEMG downregulation or ECM upregulation might affect cardiac phenotype.
Performing a meta-analysis on public expression data we identified two genes mapping to chromosome 21 (Hsa21), namely NRIP1/ RIP140 (nuclear receptor interacting protein 1) and RUNX1 (Runt related transcription factor 1), as good candidates for NEMG downregulation and ECM upregulation, respectively. These genes are overexpressed in DS cells and in heart tissue.
NRIP1 negatively regulates PGC-1α, a master regulator of the mitochondrial function. We attenuated by siRNA NRIP1 expression in a cell model of DS demonstrating an inverse correlation between NRIP1 and PGC-1α expression, together with an improvement of mitochondrial function in silenced cells. We therefore developed a strategy to correct mitochondrial alterations in DS by pharmacologically stimulating the activity of the NRIP1 targets PGC-1α and PPARs. To this aim we supplemented cultures of DS-HFFs with drugs affecting PGC-1α, namely Metformin and Pioglitazone, to evaluate their modulatory impact on mitochondrial function.
We found both strategies effective on rescuing mitochondrial function in terms of oxigen consumption, ATP production and mitochondrial biogenesis.

description: The role played by a Lorentz-violating term on the outcomes of kink scattering in the $ϕ^6$ model is investigated by using the Fourier spectral method. Impacts of the Lorentz-violating term on the critical velocities, the location of two-bounce windows, and the maximal values of various types of energy densities are analyzed. Some novel features of kink-antikink collisions are discussed. The interactions between three and four kinks are also considered.

description: The Santa Teresa Campus of the University of Florence has undergone a huge transformation from a 17th century convent, to the prison of the 19th and 20th centuries, and then to a 21st century university campus. Over four centuries, the form has evolved from closed to open. With the help of literature survey, field research and typological analysis of urban form, this paper analyzes the renovation strategies from three aspects. From the perspective of an open educational space, the case transforms the original internal communication space into an exhibition space open to the city. From the perspective of perceptible history, the case preserves the historic space structure and allows important historical elements to be easily seen and touched. From the perspective of the revival of the historic city, the case has become an important node of the revival by building connections of functions and activities with surrounding places. Finally, this paper summarizes three design strategies and four social conditions required for the transition from enclosed to shared urban form, making contributions to future practice.

Identification of PATZ1-Targeting miRNAs in thyroid cancer
Creators: name: Vitiello, Michela
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: Thyroid cancer is one of the most frequent malignancies of the endocrine system, and its incidence is predicted to become the fourth leading cancer diagnosis by 2030. In spite of the progressive knowledge of the molecular mechanisms involved in thyroid transformation, its prognosis remains unpredictable and the identification of new biological markers are needed in addition to already known molecules, to correctly stratify patients at risk of recurrence and progression, eventually providing new targeted therapies. We recently showed that the transcriptional regulator PATZ1 is constantly down-regulated in human thyroid cancer and acts as a tumor suppressor in thyroid cancer cell lines by targeting p53-dependent genes involved in Epithelial-Mesenchymal Transition and cell migration.  The aim of the present work was to elucidate the upstream signaling pathway regulating PATZ1 expression during thyroid transformation. We first identified miR-23b and miR-29b to specifically target PATZ1 expression, which was inversely correlated to their expression in rat thyroid cells stimulated to proliferate with Thyroid-stimulating hormone (TSH). Next, using an inducible cell system, we found that miR-29b was up-regulated by oncogenic Ras during transformation of FRTL-5 rat thyroid cells toward an undifferentiated phenotype resembling that of anaplastic carcinomas and characterized by the acquisition of a migratory and invasive behavior. Conversely, PATZ1 was down-regulated, with an inverse correlation compared to miR-29b expression, and was specifically targeted by miR-29b in untransformed FRTL-5 cells. Restoration of PATZ1 expression in FRTL-5 cells stably expressing oncogenic Ras inhibited cell proliferation and migration, indicating a key role of PATZ1 in Ras-driven thyroid transformation. These results confirm the tumor suppressor role of PATZ1 in thyroid cancer and suggest that its downregulation in thyroid cancer requires the activation of Ras GTPase signaling via miR-29b.

description: The unlabeled sensing problem is to solve a noisy linear system of equations under unknown permutation of the measurements. We study a particular case of the problem where the permutations are restricted to be r-local, i.e. the permutation matrix is block diagonal with r x r blocks. Assuming a Gaussian measurement matrix, we argue that the r-local permutation model is more challenging compared to a recent sparse permutation model. We propose a proximal alternating minimization algorithm for the general unlabeled sensing problem that provably converges to a first order stationary point. Applied to the r-local model, we show that the resulting algorithm is efficient. We validate the algorithm on synthetic and real datasets. We also formulate the 1-d unassigned distance geometry problem as an unlabeled sensing problem with a structured measurement matrix.

description: Spatial diffusion of particles in periodic potential models has provided a good framework for studying the role of chaos in global properties of classical systems. Here a bidimensional "soft" billiard, classically modeled from an optical lattice hamiltonian system, is used to study diffusion transitions with the control parameters variation. Sudden transitions between normal and ballistic regimes are found and characterized by inspection of the topological changes in phase-space. Transitions correlated with increases in global stability area are shown to occur for energy levels where local maxima points become accessible, deviating trajectories approaching it. These instabilities promote a slowing down of the dynamics and an island myriad bifurcation phenomenon, along with the suppression of long flights within the lattice. Other diffusion regime variations occurring during small intervals of control parameters are shown to be related to the emergence of a set of orbits with long flights, thus altering the total average displacement for long integration times but without global changes in phase-space.

description: The existence theory is developed for solutions of the inhomogeneous linearized field equations for causal variational principles. These equations are formulated weakly with an integral operator which is shown to be bounded and symmetric on a Hilbert space endowed with a suitably adapted weighted $L^2$-scalar product. Guided by the procedure in the theory of linear elliptic partial differential equations, we use the spectral calculus to define Sobolev-type Hilbert spaces and invert the linearized field operator as an operator between such function spaces. The uniqueness of the resulting weak solutions is analyzed. Our constructions are illustrated in simple explicit examples. The connection to the causal action principle for static causal fermion systems is explained.

description: Learning from 3D point-cloud data has rapidly gained momentum, motivated by the success of deep learning on images and the increased availability of 3D~data. In this paper, we aim to construct anisotropic convolution layers that work directly on the surface derived from a point cloud. This is challenging because of the lack of a global coordinate system for tangential directions on surfaces. We introduce DeltaConv, a convolution layer that combines geometric operators from vector calculus to enable the construction of anisotropic filters on point clouds. Because these operators are defined on scalar- and vector-fields, we separate the network into a scalar- and a vector-stream, which are connected by the operators. The vector stream enables the network to explicitly represent, evaluate, and process directional information. Our convolutions are robust and simple to implement and match or improve on state-of-the-art approaches on several benchmarks, while also speeding up training and inference.

title: A Machine Learning Approach to Mitigating Radio Interference in Deep Wide-field Observations of the Lockman Hole
Creators: name: Brooks, Jacob Edward
Publisher: name: University of Central Lancashire
Year: 2024

description: A study of the Lockman Hole at 1.5GHz with the e-MERLIN radio telescope is performed, along with an experiment in using machine learning techniques to identify and remove interference in astronomical radio observations, and an investigation of a faint sub-kpc scale binary black hole candidate. It is found that manually flagged observations used as the basis for a training set does not produce a trained network that performs better than the current state of the art statistical tool, at least when using a GAN architecture. Though, it remains possible that refinements to the GAN model, the pre-processing method, and the training set could produce better results. Machine learning techniques remain as one of the most promising methods of dealing with interference in an increasingly difficult RFI environment populated by massive satellite networks that will impede the operation of next generation radio observatories, such as the SKA. In the investigation of the sub-kpc scale binary AGN candidate, two radio sources are detected that overlap with two previously identified stellar cores, both with a separation of � 1". Specifically, the local epoch separation between the two radio sources is measured as 0.95�0.29 kpc. However, follow up radio observations with greater resolving power did not produce a second detection. The source is very faint, so it is likely these observations were not sensitive enough to provide a second detection; further observation is recommended to reduce the noise level. Finally, a source catalogue of 78 sources in the Lockman Hole is produced from a wide field image with a mean sensitivity of 12�Jy/beam. Radio measurements from other studies at 140MHz and 3GHz are included for � 50% of sources, along with estimates of redshift for 35 sources. Five sources from this new catalogue are studied in detail and the differential source counts are calculated and compared with similar work. The source counts are consistent with an observed faint radio population with a suppressed SFG component at . 1mJy, which is expected at VLBI scales. The overall trend agrees with source counts calculated using a catalogue of VLA sources. The e-MERLIN image is an important step towards producing a deeper radio image of the Lockman Hole that can be used to classify sources within the field, and investigate the nature of the faint radio population.
A combination of the neutrino trimaximal mixings and mu-tau reflection symmetry in the type-I seesaw model

Year: 2021

description: In this paper, we make an attempt to combine the neutrino trimaximal (TM1 and TM2) mixings and $μ$-$τ$ reflection symmetry in the type-I seesaw model. Such a scenario is highly restrictive and predictive: in addition to three right-handed neutrino masses, there are only five real parameters; all the lepton flavor mixing parameters except for $θ^{}_{13}$ will be predicted. The relations between the model parameters and the measurable neutrino parameters will be derived. The implications of this scenario for leptogenesis will be explored in detail. A further reduction of this scenario to the more restrictive and predictive minimal seesaw model with only two right-handed neutrinos will also be considered. In addition, we will also discuss a possible approach to get the desired mass matrices and study the compatibility of the trimaximal $μ$-$τ$ reflection symmetry with texture zeros.

description: We explore and systematically compare the morphological, structural and optical properties of GaN/(Al,Ga)N multiple quantum wells (MQWs) grown by plasma-assisted molecular beam epitaxy (PA-MBE) on freestanding GaN$(0001)$ and GaN$(000\bar{1})$ substrates. Samples of different polarity are found to be comparable in terms of their morphological and structural perfection and exhibit essentially identical quantum well widths and Al content. Regardless of the crystal orientation, the exciton decay in the MQWs at 10 K is dominantly radiative and the photoluminescence (PL) energy follows the quantum confined Stark effect (QCSE) for different quantum well widths. A prominent free-to-bound transition involving interface shallow donors is, however, visible for the N-polar MQWs. At room-temperature, in contrast, the exciton decay in all samples is dominated by nonradiative recombination taking place at point defects, presumably Ca or V N located at the bottom QW interface. Remarkably, the N-polar MQWs exhibit a higher PL intensity and longer decay times than the Ga-polar MQWs at room-temperature. This improved internal quantum efficiency is attributed to the beneficial orientation of the internal electric field that effectively reduces the capture rate of minority carriers by interface trap states.

Artificial intelligence (AI) reconfigures work and organization, while work and organization shape AI. In this special issue, we explore these mutual transformations and how they play out across industries and occupations. We argue that, to truly appreciate this transformative power, the use of AI should be understood in relation to key dimensions of the work context. In this editorial, we discuss the sociotechnical dynamics of AI implementation, the research landscape of AI in the context of work, and key contextual factors on the macro‐ and micro‐level that help understand the AI‐work nexus. We then provide directions for future research at the intersection of work and AI.

description: Magnetic energy around astrophysical compact objects can strongly dominate over plasma rest mass. Emission observed from these systems may be fed by dissipation of Alfvén wave turbulence, which cascades to small damping scales, energizing the plasma. We use 3D kinetic simulations to investigate this process. When the cascade is excited naturally, by colliding large-scale Alfvén waves, we observe quasithermal heating with no nonthermal particle acceleration. We also find that the particles are energized along the magnetic field lines and so are poor producers of synchrotron radiation. At low plasma densities, our simulations show the transition to "charge-starved" cascades, with a distinct damping mechanism.

description: We use 118 H$β$ quasar (QSO) observations in the redshift range $0.0023 \leq z \leq 0.89$ to simultaneously constrain cosmological model parameters and QSO 2-parameter radius-luminosity ($R-L$) relation parameters in six different cosmological models. We find that the $R-L$ relation parameters for these QSOs are independent of the assumed cosmology so these QSOs seem to be standardizable through the $R-L$ relation (although there is a complication that might render this untrue). Cosmological constraints obtained using these QSOs are weak, more favor currently decelerated cosmological expansion, and typically are in $\sim 2σ$ tension with those obtained from a joint analysis of baryon acoustic oscillation and Hubble parameter measurements. Extending the $R-L$ relation to a 3-parameter one to try to correct for the accretion rate effect does not result in a reduction of the cosmological constraints discrepancy nor does it result in the hoped-for significant reduction of the intrinsic scatter of the $R-L$ relation.

description: The orbital multiplicity in multiband superconductors yields orbital differentiation in normal-state properties, and can lead to orbital-selective spin-fluctuation Cooper pairing. This phenomenon has become increasingly pivotal in clarifying the pairing 'enigma' particularly for multiband high-temperature superconductors. In one-unit-cell (1-UC) FeSe/SrTiO3, the thinnest and highest-Tc member of iron-based superconductors, the standard electron-hole Fermi pocket nesting scenario is apparently not applicable since the Gamma-centered hole pockets are absent, so the actual pairing mechanism is the subject of intense debate. Here, by measuring high-resolution Bogoliubov quasiparticle interference, we report observations of highly anisotropic magnetic Cooper pairing in 1-UC FeSe. From a theoretical point of view, it is important to incorporate effects of electronic correlations within a spin-fluctuation pairing calculation, where the dxy orbital becomes coherence-suppressed. The resulting pairing gap is compatible with the experimental findings, which suggests that high-Tc Cooper pairing with orbital selectivity applies to 1-UC FeSe. Our findings imply the general existence of orbital selectivity in iron-based superconductors and the universal importance of electron correlations in high-Tc superconductors.

description: Objectives—We assessed the effects of syringe exchange program (SEP) policy on rates of HIV risk behavior and HIV incidence among injection drug users. Methods—Using a multivariate generalized estimating equation and Cox regression methods, we examined syringe borrowing, syringe lending, and HIV incidence among a prospective cohort of 1228 injection drug users in Vancouver, British Columbia. Results—We observed substantial declines in rates of syringe borrowing (from 20.1% in 1998 to 9.2% in 2003) and syringe lending (from 19.1% in 1998 to 6.8% in 2003) following SEP policy change. These declines coincided with a statistically significant increase in the proportion of participants accessing sterile syringes from nontraditional SEP sources (P<.001). In multivariate analyses, the period following the change in SEP policy was independently associated with a greater than 40% reduction in syringe borrowing (adjusted odds ratio [AOR]=0.57; 95% confidence interval [CI]=0.49, 0.65) and lending (AOR=0.52; 95% CI=0.45, 0.60), as well as declining HIV incidence (adjusted hazard ratio=0.13; 95% CI=0.06, 0.31). Conclusions—Widespread syringe distribution appears to be a more effective SEP policy than do more restrictive SEP policies that limit syringe access. Efforts should be made to ensure that SEP policies and program design serve to maximize rather than hinder syringe access.

description: A momentum-dependent formulation based on a stationary spin-0 and isospin-1 dibaryon field is proposed to improve convergence of chiral effective field theory in the $\cs{1}{0}$ channel of $NN$ scattering. Although the two-parameter leading-order interaction appears to be unnatural, it nevertheless has the necessary features of an effective field theory. A rapid order-by-order convergence is found in $\cs{1}{0}$. As an application beyond the two-body level, the triton binding energy is studied and compared to standard chiral effective field theory with partly perturbative pions. The consistency of the chiral Lagrangian for the new formulation is examined by working out the pionic radiative corrections, and consequences of nontrivial chiral-connection terms are discussed.

description: Community structure along marine shores varies considerably even within biogeographic regions. Nearshore processes often explain broad patterns of intertidal biological variation, but most studies to date have been conducted in temperate systems largely influenced by upwelling dynamics. On the Atlantic coast of Canada, upwelling is not a major feature and sea ice constitutes an important source of variation. Thus, in 2014 we conducted a study on this coast with the objective of investigating benthic-pelagic coupling affecting intertidal communities. Essentially, we determined the latitudinal changes in rocky intertidal communities along 400 km of coastline in Nova Scotia and examined nearshore factors related to such changes. First, using field and remote-sensing data, we documented the geographic variation in coastal ice load in early spring and the nearshore abundance of phytoplankton and particulate carbon (food for intertidal filter-feeders) afterwards. Then, using cleared quadrats and mesh collectors, we measured the recruitment rate of barnacles (spring) and mussels (spring to fall) in nine wave-exposed locations spanning the studied coastal range. Lastly, we quantified the summer abundance of all macroscopic intertidal algae and invertebrates using 250 quadrats spread throughout those locations. We analyzed the results using standard statistical procedures.

In the early spring of 2014, sea ice formed in the winter in the Gulf of St. Lawrence drifted out of that gulf and scoured intertidal habitats along the northern Atlantic coast of Nova Scotia, causing high biomass losses. Central and southern shores were unaffected by ice and retained abundant algae and invertebrates. Recolonization of the disturbed shores started quickly, mainly by barnacles and secondarily by fucoid algae. Mussel recruitment along the studied coast was weak in the spring and strong in late summer and early fall. Overall, barnacle recruitment peaked at a northern location and at two nearby southern locations, while mussel recruitment peaked at one of those southern locations. The latitudinal changes in nearshore phytoplankton abundance and particulate carbon broadly coincided with those recruitment trends. The changes in the abundance of dogwhelks (the main predators of barnacles and mussels) along the coast largely followed the barnacle and mussel recruitment trends. Species richness peaked at one of the productive southern locations. We conclude that intertidal community structure along the Atlantic Canadian coast is influenced in part by drift sea ice and by nearshore food supply, which appears to cause bottom-up community regulation through barnacle and mussel recruitment.

description: In September 2015, we received a credible report that Gila Topminnow Poeciliopsis occidentalis had been seen in Parker Canyon, Santa Cruz County, Arizona. The report was made by a retired U.S. Forest Service wildlife biologist, who had seen Gila Topminnow in the wild before. Timmons and Paulus surveyed the location on 30 September and observed and captured numerous poeciliids. When processing captured fish, Timmons identified topminnow, subsequently confirmed by Paulus. Duncan and others have since confirmed that identification. Western mosquitofish Gambusia affinis were also present. Parker Canyon is in the San Rafael Valley, which had three naturally occurring Gila topminnow sites; Santa Cruz River, Sharp Spring, and Sheehy Spring. The San Rafael Valley is also the headwaters for the Santa Cruz River. Parker Canyon is a major drainage on the east side of the valley largely on the Coronado National Forest, and contains Parker Canyon Lake. The surveyed site is on the National Forest, and downstream of Parker Canyon Lake. Parker Canyon Lake is the likely source of the Western Mosquitofish and other nonnative fish that have historically occurred in Parker Canyon below the lake. Parker Canyon empties into the Rio Santa Cruz in Mexico, about 2.5 km south of the International Border. In June 2006, we found three stream reaches of the Rio Santa Cruz in Mexico with water and fishes. Opportunistic surveys at the upstream-most site, 13 km below the border and 10 km below the confluence with Parker Canyon, found only western mosquitofish. The second watered section was 17 km below the border and preliminary surveys here we found all size classes of Gila Topminnow, and no Western Mosquitofish. The third site was another six kilometers downstream and our preliminary surveys found all size classes of Gila Topminnow, and no Western Mosquitofish. We need to have a genetic analysis of these topminnow to determine if they are a remnant, historical population, immigrants from Mexico, or may have been transported by humans. If this is a naturally occurring population, it is an incredibly important find, and of great conservation importance. The presence of nonnative fishes, especially Western Mosquitofish, at this site is of great concern. We will further discuss our findings, conservation implications, and plans for these Gila topminnow.

description: Fog computing is a new computational paradigm that emerged from the need to reduce network usage and latency in the Internet of Things (IoT). Fog can be considered as a continuum between the cloud layer and IoT users that allows the execution of applications or storage/processing of data in network infrastructure devices. The heterogeneity and wider distribution of fog devices are the key differences between cloud and fog infrastructure. Genetic-based optimization is commonly used in distributed systems; however, the differentiating features of fog computing require new designs, studies, and experimentation. The growing research in the field of genetic-based fog resource optimization and the lack of previous analysis in this field have encouraged us to present a comprehensive, exhaustive, and systematic review of the most recent research works. Resource optimization techniques in fog were examined and analyzed, with special emphasis on genetic-based solutions and their characteristics and design alternatives. We defined a classification of the optimization scope in fog infrastructures and used this optimization taxonomy to classify the 70 papers in this survey. Subsequently, the papers were assessed in terms of genetic optimization design. Finally, the benefits and limitations of each surveyed work are outlined in this paper. Based on these previous analyses of the relevant literature, future research directions were identified. We concluded that more research efforts are needed to address the current challenges in data management, workflow scheduling, and service placement. Additionally, there is still room for improved designs and deployments of parallel and hybrid genetic algorithms that leverage, and adapt to, the heterogeneity and distributed features of fog domains.
