description: Background Receptor-activated SMADs trimerize with SMAD4 to regulate context-dependent target gene expression. However, the presence of a single SMAD1/5/8 binding motif in cis-regulatory elements alone does not trigger transcription in native contexts. We hypothesize that binding to composite motifs in which at least two SMAD binding sites are in close proximity would be enough to induce transcription as this scenario allows the simultaneous interaction of at least two SMAD proteins, thereby increasing specificity and affinity. Results Using more than 65 distinct firefly luciferase constructs, we delineated the minimal requirements for BMP-induced gene activation. We propose a model in which two SMAD-MH1 domains bind a SMAD-composite motif in a back-to-back fashion with a 5-bp distance between the SMAD-motifs on opposing DNA strands. However screening of SMAD1-bound regions across a variety of cell types highlights that these composite motifs are extremely uncommon, explaining below 1% of SMAD1 binding events. Conclusions Deviations from these minimal requirements prevent transcription and underline the need for co-transcription factors to achieve gene activation.

description: Vertical convection is investigated using direct numerical simulations over a wide range of Rayleigh numbers $10^7\le Ra\le10^{14}$ with fixed Prandtl number $Pr=10$, in a two-dimensional convection cell with unit aspect ratio. It is found that the dependence of the mean vertical centre temperature gradient $S$ on $Ra$ shows three different regimes: In regime I ($Ra \lesssim 5\times10^{10}$), $S$ is almost independent of $Ra$; In the newly identified regime II ($5\times10^{10} \lesssim Ra \lesssim 10^{13}$), $S$ first increases with increasing $Ra$ (regime ${\rm{II}}_a$), reaches its maximum and then decreases again (regime ${\rm{II}}_b$); In regime III ($Ra\gtrsim10^{13}$), $S$ again becomes only weakly dependent on $Ra$, being slightly smaller than in regime I. The transitions between diffeereent regimes are discussd. In the three different regimes, significantly different flow organizations are identified: In regime I and regime ${\rm{II}}_a$, the location of the maximal horizontal velocity is close to the top and bottom walls; However, in regime ${\rm{II}}_b$ and regime III, banded zonal flow structures develop and the maximal horizontal velocity now is in the bulk region. The different flow organizations in the three regimes are also reflected in the scaling exponents in the effective power law scalings $Nu\sim Ra^β$ and $Re\sim Ra^γ$. In regime I, the fitted scaling exponents ($β\approx0.26$ and $γ\approx0.51$) are in excellent agreement with the theoretical predication of $β=1/4$ and $γ=1/2$ for laminar VC (Shishkina, {\it{Phys. Rev. E.}} 2016, 93, 051102). However, in regimes II and III, $β$ increases to a value close to 1/3 and $γ$ decreases to a value close to 4/9. The stronger $Ra$ dependence of $Nu$ is related to the ejection of plumes and larger local heat flux at the walls.

Molecular basis of Osteoarthritis and aspects of
cellular senescence in disease

Subjects: BIO/16 Anatomia umana

description: The aim of this study is to investigate on some molecular mechanisms contributing to the pathogenesis of osteoarthritis (OA) and in particular to the senescence of articular chondrocytes. It is focused on understanding molecular events downstream GSK3β inactivation or dependent on the activity of IKKα, a kinase that does not belong to the phenotype of healthy articular chondrocytes. Moreover, the potential of some nutraceuticals on scavenging ROS thus reducing oxidative stress, DNA damage, and chondrocyte senescence has been evaluated in vitro. 
The in vitro LiCl-mediated GSK3β inactivation resulted in increased mitochondrial ROS production, that impacted on cellular proliferation, with S-phase transient arrest, increased SA-β gal and PAS staining, cell size and granularity. ROS are also responsible for the of increased expression of two major oxidative lesions, i.e. 1) double strand breaks, tagged by γH2AX, that associates with activation of GADD45β and p21, and  2) 8-oxo-dG adducts, that associate with increased IKKα and MMP-10 expression. The pattern observed in vitro was confirmed on cartilage from OA patients. 
IKKa dramatically affects the intensity of the DNA damage response induced by oxidative stress (H2O2 exposure)  in chondrocytes, as evidenced by  silencing strategies. At early time point an higher percentage of γH2AX positive cells and more foci in IKKa-KD cells are observed, but IKKa KD cells proved to almost completely recover after 24 hours respect to their controls. Telomere attrition is also reduced in IKKaKD. Finally MSH6 and MLH1 genes are up-regulated in  IKKαKD cells but not in control cells. 
Hydroxytyrosol and Spermidine have a great ROS scavenging capacity in vitro. Both treatments revert the H2O2 dependent increase of cell death and γH2AX-foci formation and senescence, suggesting the ability of increasing cell homeostasis. These data indicate that nutraceuticals represent a great challenge in OA management, for both therapeutical and preventive purposes.
From quantum mechanics to classical statistical physics: generalized Rokhsar-Kivelson Hamiltonians and the "Stochastic Matrix Form" decomposition

description: Quantum Hamiltonians that are fine-tuned to their so-called Rokhsar-Kivelson (RK) points, first presented in the context of quantum dimer models, are defined by their representations in preferred bases in which their ground state wave functions are intimately related to the partition functions of combinatorial problems of classical statistical physics. We show that all the known examples of quantum Hamiltonians, when fine-tuned to their RK points, belong to a larger class of real, symmetric, and irreducible matrices that admit what we dub a Stochastic Matrix Form (SMF) decomposition. Matrices that are SMF decomposable are shown to be in one-to-one correspondence with stochastic classical systems described by a Master equation of the matrix type, hence their name. It then follows that the equilibrium partition function of the stochastic classical system partly controls the zero-temperature quantum phase diagram, while the relaxation rates of the stochastic classical system coincide with the excitation spectrum of the quantum problem. Given a generic quantum Hamiltonian construed as an abstract operator defined on some Hilbert space, we prove that there exists a continuous manifold of bases in which the representation of the quantum Hamiltonian is SMF decomposable, i.e., there is a (continuous) manifold of distinct stochastic classical systems related to the same quantum problem. Finally, we illustrate with three examples of Hamiltonians fine-tuned to their RK points, the triangular quantum dimer model, the quantum eight-vertex model, and the quantum three-coloring model on the honeycomb lattice, how they can be understood within our framework, and how this allows for immediate generalizations, e.g., by adding non-trivial interactions to these models.

description: This paper presents an experimental and numerical investigation of solid-liquid fluidized beds consisting of bonded spheres in very narrow tubes, i.e., when the ratio between the tube and grain diameters is small. In narrow beds, high confinement effects have proved to induce crystallization, jamming and different patterns, which can be intensified or modified if some grains are bonded together. In order to investigate that, we produced duos and trios of bonded aluminum spheres with diameter of 4.8 mm, and formed beds consisting either of 150-300 duos or 100-200 trios in a 25.4 mm-ID pipe, which were submitted to water velocities above those necessary for fluidization. For the experiments, we filmed the bed with high-speed and conventional cameras and processed the images, obtaining measurements at both the bed and grain scales. For the numerical part, we computed the bed evolution for the same conditions with a CFD-DEM (computational fluid dynamics - discrete element method) code. Our results show distinct motions for individual duos and trios, and different structures within the bed. We also found that jamming may occur suddenly for trios, where even the microscopic motion (fluctuation at the grain scale) stops, calling into question the fluidization conditions for those cases.

title: Technological embodiment and haptic narrative: postphenomenology in cinema, interactive art and computer gaming

description: Within this thesis I incorporate Don Ihde’s philosophy of technology to consider the human body’s relationship to three contrasting types of media in the form of cinema, interactive art and computer gaming. Using Ihde’s concept of postphenomenology, I consider how corporeality changes with different technological devices and how engagement with each of these contrasting media contributes towards a unique co-creation of story between a body and a technology.
Across three chapters I examine how a user’s experience of fictional stories changes based upon the relationships between media and the user’s body, understood through the framework of postphenomenology. This is considered through Ihde’s key concepts of human-technology relationships, which simultaneously amplify and reduce experiences of bodyhood. In Chapter 1 I consider this through the textual analysis of a number of first person point-of- view films including Franck Khalfoun’s Maniac (2012) and Julian Schabel’s Le scaphandre et le papillon (The Diving Bell and Butterfly, 2007).
In Chapter 2 this is expanded upon through analysis of interactive art installations and original interviews with artists. These include Blast Theory’s A Machine to See With (2010), Toni Dove’s Artificial Changelings (1998) and Dennis Del Favero’s Scenario (2011). Chapter 3 considers the postphenomenology of the playing body through titles that range from the Grand Theft Auto franchise (2001-present, Rockstar Games) to smaller independent games such as The Novelist (2013, Orthogonal Games) and This War of Mine (2014, 11 bit studios).
Using Ihde’s framework, this thesis contributes a new approach to film and media studies by applying postphenomenology to consider different types of fictional experiences. This is a concept that moves viewers and participants of screen and media culture towards a haptic, corporeal and postphenomenological comprehension of narrative.

description: We show that by taking a certain scaling limit of a Euclideanised form of the Plebanski-Demianski metrics one obtains a family of local toric Kahler-Einstein metrics. These can be used to construct local Sasaki-Einstein metrics in five dimensions which are generalisations of the Y^{p,q} manifolds. In fact, we find that these metrics are diffeomorphic to those recently found by Cvetic, Lu, Page and Pope. We argue that the corresponding family of smooth Sasaki-Einstein manifolds all have topology S^2 x S^3. We conclude by setting up the equations describing the warped version of the Calabi-Yau cones, supporting (2,1) three-form flux.

description: Two-dimensional superconductors attract great interest both for their fundamental physics and for their potential applications, especially in the rapidly growing field of quantum computing. Despite intense theoretical and experimental efforts, materials with a reasonably high transition temperature are still rare. Even more rare are those that combine superconductivity with a non-trivial band topology, to potentially host exotic states of matter such as Majorana fermions. Here, we predict a remarkably high superconducting critical temperature of 21-28 K in the easily exfoliable, topologically non-trivial 2D semimetal W2N3 . By studying its electronic and superconducting properties as a function of doping and strain, we find large changes in the electron-phonon interactions that make this material a unique platform to study different coupling regimes and test the limits of current theories of superconductivity. Last, we discuss the possibility of tuning the material to achieve coexistence of superconductivity and topologically non-trivial edge states.

description: Italy has a preeminent rank in kiwifruit industry, being the first exporter and the second largest producer after China. However, in the last years kiwifruit yields and the total cultivated area considerably decreased, due to the pandemic spread of the bacterial canker caused by Pseudomonas syringae pv. actinidiae (Psa). Several climatic conditions and cultural practices affect the development of the bacterial canker. This research work focused on the impact of agricultural practices and microclimate conditions on the incidence and epidemiology of Psa in the orchard. Therefore, the effect of fertilization, irrigation, use of bio-regulators, rootstock, training system and pruning were examined. The effect of different tunnel systems was analyzed as well, to study the plant-pathogen interaction. Considering the importance of insects as vectors in other pathosystems, the role of Metcalfa pruinosa in the spread of the bacterial canker was investigated in controlled conditions. In addition, quality and storage properties of fruits from infected plants were assessed. The study of all these aspects of the agronomic practices is useful to define a strategy to limit the bacterial diffusion in the orchard. Overall, excess nitrogen fertilization, water stress, stagnant water supplies, pruning before summer and the high number of Metcalfa pruinosa increased the Psa incidence. In contrast, tunnel covers may be useful for the control of the disease, with special attention to the kind of material.

description: Symmetric non-expanding horizons are studied in arbitrary dimension. The global properties -as the zeros of infinitesimal symmetries- are analyzed particularly carefully. For the class of NEH geometries admitting helical symmetry a quasi-local analog of Hawking's rigidity theorem is formulated and proved: the presence of helical symmetry implies the presence of two symmetries: null, and cyclic. The results valid for arbitrary-dimensional horizons are next applied in a complete classification of symmetric NEHs in 4-dimensional space-times (the existence of a 2-sphere crossection is assumed). That classification divides possible NEH geometries into classes labeled by two numbers - the dimensions of, respectively, the group of isometries induced in the horizon base space and the group of null symmetries of the horizon.

description: This paper studies information orders in screening models. I amend a general screening problem with a signal about the agent's type. The principal prefers one signal to another for any preferences of principal and agent if and only if the signals are ranked by Blackwell's order. Under a standard regularity condition, a novel information order – the hazard rate spread (HRS) order – characterizes a robust ranking of signals by the principal. I relate the HRS order to well-known information orders and provide sufficient conditions for other welfare measures than the principal's payoff to increase or decrease in the HRS order.
QSP, optimization software for preform tailoring

Subjects: Thermoplastic composite, design, optimization

description: QSP can produce complex-shaped parts with a production line pulse-time of 40-90 seconds. For example, using QSP, an omega-shaped profile molded into an L-shaped beam integrates 13 patches of 1.5-, 2- and 3-millimeter thick organosheet (woven fabric thermoplastic prepreg) and UD tape into a 6-millimeter-thick part with a cycle time of less than 77 seconds per part. However, to take advantage of automation technology such as QSP, engineers must develop design and optimization methods that can evaluate many theoretical combinations of partial plies and the corresponding variation in the number, thickness, position and composition of plies (for example, reinforcement type and fiber orientation). With this in mind, Cetim has combined its experience in composites structural analysis, nondestructive testing (NDT) and manufacturing with the expertise of ONERA (The French Aerospace Lab) in advanced optimization methods used for years in the aerospace industry. The result is QSD, a tool now available in Altair Engineering’s (Troy, Mich., U.S.) HyperWorks computer-aided engineering (CAE) software. It is basically an optimization add-on that helps to design composite parts made using tape- and organosheet-based processes and to control their cost, including how to reuse production scrap for zero-waste, closed-loop manufacturing.

description: Additively manufactured metals exhibit heterogeneous microstructure which dictates their material and failure properties. Experimental microstructural characterization techniques generate a large amount of data that requires expensive computationally resources. In this work, an optimized machine learning (ML) framework is proposed to autonomously and efficiently characterize pores, particles, grains and grain boundaries (GBs) from a given microstructure image. First, using a classifier Convolutional Neural Network (CNN), defects such as pores, powder particles, or GBs were recognized from a given microstructure. Depending on the type of defect, two different processes were used. For powder particles or pores, binary segmentations were generated using an optimized Convolutional Encoder-Decoder Network (CEDN). The binary segmentations were used to used obtain particle and pore size and bounding boxes using an object detection ML network (YOLOv5). For GBs, another optimized CEDN was developed to generate RGB segmentation images, which were used to obtain grain size distribution using two regression CNNS. To optimize the RGB CEDN, the Deep Emulator Network SEarch (DENSE) method which employs the Covariance Matrix Adaptation - Evolution Strategy (CMA-ES) was implemented. The optimized RGB segmentation network showed a substantial reduction in training time and GPU usage compared to the unoptimized network, while maintaining high accuracy. Lastly, the proposed framework showed a significant improvement in analysis time when compared to conventional methods.

Photovoltaic power system involves designing, selecting and determining the specifications of the different components employed in the system. In this study, direct current (DC) appliances and alternative current (AC) appliances were considered. The results show that the average daily load requirement of the selected residential unit is 31.5 kWh/day. For functioning this load in off-grid necessary components are chosen and also a system design has been proposed. Installation and maintenance cost analysis of this PV system also been estimated. Therefore, for sustainability, reliability and accessibility of power, the use of stand-alone solar photovoltaic technology is recommended.

description: The phase diagram of the Gross-Neveu model in $2+1$ space-time dimensions at non-zero temperature and chemical potential is studied in the limit of infinitely many flavors, focusing on the possible existence of inhomogeneous phases, where the order parameter $σ$ is non-uniform in space. To this end, we analyze the stability of the energetically favored homogeneous configuration $σ(\textbf{x}) = \barσ= \textrm{const}$ with respect to small inhomogeneous fluctuations, employing lattice field theory with two different lattice discretizations as well as a continuum approach with Pauli-Villars regularization. Within lattice field theory, we also perform a full minimization of the effective action, allowing for arbitrary 1-dimensional modulations of the order parameter. For all methods special attention is paid to the role of cutoff effects. For one of the two lattice discretizations, no inhomogeneous phase was found. For the other lattice discretization and within the continuum approach with a finite Pauli-Villars cutoff parameter $Λ$, we find a region in the phase diagram where an inhomogeneous order parameter is favored. This inhomogeneous region shrinks, however, when $a$ is decreased or $Λ$ is increased, and finally diappears for all non-zero temperatures when the cutoff is removed completely. For vanishing temperature, we find hints for a degeneracy of homogeneous and inhomogeneous solutions, in agreement with earlier findings.

description: The EuroMix project aimed to develop an experimentally verified strategy for the risk assessment of mixtures of multiple chemicals. To refine cumulative and aggregated risk assessment the tiered mechanism‐based test strategy will use in silico and in vitro tools that will be verified against in vivo data. In order to group chemicals into cumulative assessment groups (CAG) one aim of Work Package 3 was the development of CAG‐specific PCR arrays to distinguish between subsets of commonly regulated genes for chemicals with different modes of action (MoA) within one CAG group. Using the concept of adverse outcome pathways (AOPs) the endpoints in EuroMix (liver toxicity, developmental toxicity and endocrine effects) were exemplarily aligned with selected CAGs by EFSA resulting in three different AOPs: AOP for liver steatosis, AOP for craniofacial skeletal malformations and AOP for endocrine (anti‐androgenic) effects.

description: Exciton-exciton annihilation (EEA) and Auger recombination are detrimental processes occurring in semiconductor optoelectronic devices at high carrier densities. Despite constituting one of the main obstacles for realizing lasing in semiconductor nanocrystals (NCs), the dependencies on NC size are not fully understood, especially for those with both weakly and strongly confined dimensions. Here, we use differential transmission spectroscopy to investigate the dependence of EEA on the physical dimensions of thickness-controlled 2D halide perovskite nanoplatelets (NPls). We find the EEA lifetimes to be extremely short on the order of 7-60 ps. Moreover, they are strongly determined by the NPl thickness with a power-law dependence according to τ_2~d^5.3. Additional measurements show that the EEA lifetimes also increase for NPls with larger lateral dimensions. These results show that a precise control of the physical dimensions is critical for deciphering the fundamental laws governing the process especially in 1D and 2D NCs.

description: In this paper, following hep-th/0501028, we present a detailed derivation and discussion of the exact gravitational field solutions for a relativistic particle localized on a tensional brane in brane-induced gravity. Our derivation yields the metrics for both the normal branch and the self-inflating branch DGP braneworlds. They generalize the 4D gravitational shock waves in de Sitter space, and so we compare them to the corresponding 4D General Relativity solution and to the case when gravity resides only in the 5D bulk, and there are no brane-localized graviton kinetic terms. We write down the solutions in terms of two-variable hypergeometric functions and find that at short distances the shock wave profiles look exactly the same as in 4D Minkowski space, thus recovering the limit one expects if gravity is to be mediated by a metastable, but long-lived, bulk resonance. The corrections far from the source differ from the long distance corrections in 4D de Sitter space, coming in with odd powers of the distance. We discuss in detail the limiting case on the self-inflating branch when gravity is modified exactly at de Sitter radius, and energy can be lost into the bulk by resonance-like processes. Finally, we consider Planckian scattering on the brane, and find that for a sufficiently small impact parameter it is approximated very closely by the usual 4D description.
description: 13 pages, 2 .eps figures, Revtex4; v4: a sign error corrected; the correction tantamount to swapping normal and self-inflating branch solutions; the only significant change is that the spectacular new instability is on the self-inflating branch in the limit of vanishing brane tension

description: Oil and gas pipeline leakages lead to not only enormous economic loss but also environmental disasters. How to detect the pipeline damages including leakages and cracks has attracted much research attention. One of the promising leakage detection method is to use lead zirconate titanate (PZT) transducers to detect the negative pressure wave when leakage occurs. PZT transducers can generate and detect guided stress waves for crack detection also. However, the negative pressure waves or guided stress waves may not be easily detected with environmental interference, e.g., the oil and gas pipelines in offshore environment. In this paper, a Gaussian mixture model based hidden Markov model (GMM-HMM) method is proposed to detect the pipeline leakage and crack depth in changing environment and time-varying operational conditions. Leakages in different sections or crack depths are considered as different states in hidden Markov models (HMM). Laboratory experiments show that the GMM-HMM method can recognize the crack depth and leakage of pipeline such as whether there is a leakage, where the leakage is.

Essays on discretionary inflation
Creators: name: Neiss, Katharine Stefanie
Publisher: name: University of British Columbia
Year: 2009

description: The focus of the following three essays rests on the Kydland-Prescott (1977) and Barro-Gordon (1983) model of time inconsistent discretionary monetary policy. The first essay derives a model in which the costs and benefits to inflation are tied to the underlying features of the economy. The benefit to inflation arises due to monopolistic competition among firms and the cost is due to a staggered timing structure for nominal money. The benefit of this approach is that it can be shown that factors that increase the monetary authority's incentive to inflate may also increase the costs to inflation, and therefore do not necessarily result in a worsened inflation bias. In particular, the model shows that discretionary inflation in the economy is nonmonotonically related to the distortion. The model also indicates that changes in the real interest rate affect the monetary authority's incentives and hence the discretionary rate of inflation. An increase in the labor share raises the discretionary rate. Lastly, lack of commitment, costs to inflation, and the presence of a distortion are crucial for discretionary inflation to be biased above the Friedman (1969) rule. The second essay builds on the first, extending the model to an open economy environment. The extended model indicates several channels through which openness affects the monetary authority's incentives. Most significantly, the model cannot replicate the Romer (1993) and Lane (1995) result that openness reduces the discretionary rate of inflation. Again, the model relates the underlying features of the economy on the discretionary rate, and an economy's foreign asset position. Strategic incentives are also important for determining whether an open economy's rate of inflation is less than that of a comparable closed economy. The last essay analyzes empirically the relationship between the overall degree of competition among firms, as measured by the markup, and the average rate of inflation for the OECD group of countries. In line with the time-consistency argument, results indicate a positive relationship between markups and inflation. This finding is robust to the inclusion of several explanatory variables, such as terms of trade effects, and central bank independence. The evidence is weak, however, in the presence of per capita GDP.

description: La Camera Spaziale Climatica (CSC) dei LNF è un progetto integrato di fisica fondamentale e di trasferimento tecnologico alle attività civili ed industriali. Nella CSC, infatti, si misurano le caratteristiche termiche ed ottiche delle componenti dei satelliti LAGEOS I e II (già operativi) e la loro evoluzione LARES (da realizzare ai LNF). Lo scopo è quello di migliorare l�??accuratezza della misura del trascinamento dello spazio-tempo in Relatività Generale (effetto Lense-Thirring) e delle applicazioni tecnologiche di Geodesia Spaziale, grazie al nuovo satellite LARES ed alla CSC. La traiettoria orbitale viene determinata con la tecnica dell�??inseguimento via laser dei satelliti da Terra (�??Satellite Laser Ranging�?�, SLR). L�??applicazione tecnologica più importante è il contributo fondamentale alla definizione del sistema internazionale di riferimento e di posizione terrestre (ITRF, Intern. Terrestrial Reference Frame), emesso dallo IERS  (Intern. Earth rotation and Reference systems Service). Esso è lo standard per tutte le attività civili, industriali e scientifiche, a Terra e nello spazio, che necessitano di un sistema di riferimento assoluto. Le misure effettuate nella CSC saranno, inoltre, estremamente utili all�??integrazione tra GNSS (Global Navigation Satellite System) ed SLR, che avrà compimento sulle future costellazioni GALILEO (Europa, ≥ 2008) e GPS-3 (USA, ≥ 2011). SLR fornisce il sistema di riferimento assoluto ed il GNSS permette la navigazione in tempo reale rispetto ad esso: il meglio delle due tecnologie, dallo spazio per la Terra.

description: We construct the Numerical Galaxy Catalog ($ν$GC), based on a semi-analytic model of galaxy formation combined with high-resolution N-body simulations in a $Λ$-dominated flat cold dark matter ($Λ$CDM) cosmological model. The model includes several essential ingredients for galaxy formation, such as merging histories of dark halos directly taken from N-body simulations, radiative gas cooling, star formation, heating by supernova explosions (supernova feedback), mergers of galaxies, population synthesis, and extinction by internal dust and intervening HI clouds. As the first paper in a series using this model, we focus on basic photometric, structural and kinematical properties of galaxies at present and high redshifts. Two sets of model parameters are examined, strong and weak supernova feedback models, which are in good agreement with observational luminosity functions of local galaxies in a range of observational uncertainty. Both models agree well with many observations such as cold gas mass-to-stellar luminosity ratios of spiral galaxies, HI mass functions, galaxy sizes, faint galaxy number counts and photometric redshift distributions in optical pass-bands, isophotal angular sizes, and cosmic star formation rates. In particular, the strong supernova feedback model is in much better agreement with near-infrared (K'-band) faint galaxy number counts and redshift distribution than the weak feedback model and our previous semi-analytic models based on the extended Press-Schechter formalism.

description: The thermal tolerance of species may be exceeded by the predicted temperature increases and thus contribute to species extinction. However, the impact of temperature increases is thought to vary between climate regions and across latitudes. Here, we aim to establish the vulnerability of an ectothermic insect to a warming climate by estimating the thermal safety margin in Ischnura heterosticta damselflies. We measured the critical thermal maximum (CTmax) along a latitudinal gradient of 17° from 21 populations along the eastern coast of Australia. Our results showed that damselflies inhabiting tropical regions had higher CTmax than temperate damselflies. CTmax increased with increasing mean temperature and decreasing latitude. We further found a positive correlation between damselfly parasite number and temperature. Body size, body condition and sex had no impact on CTmax. Our projections showed that the damselfly thermal safety margin will be narrower in the tropics compared with temperate regions under a predicted 2.6°C annual mean temperature (future projected – current) increase for the years 2061–2080. Therefore, damselflies in the tropics are likely to be more vulnerable to climate change-driven extinction even though they have a relatively higher CTmax. Nevertheless, behaviour, temperature adaptation and thermal plasticity might mitigate predicted vulnerability.
Performance of cavity-parametric amplifiers, employing Kerr nonlinearites, in the presence of two-photon loss

description: Two-photon loss mechanisms often accompany a Kerr nonlinearity. The kinetic inductance exhibited by superconducting transmission lines provides an example of a Kerr-like nonlinearity that is accompanied by a nonlinear resistance of the two-photon absorptive type. Such nonlinear dissipation can degrade the performance of amplifiers and mixers employing a Kerr-like nonlinearity as the gain or mixing medium. As an aid for parametric amplifier design, we provide a quantum analysis of a cavity parametric amplifier employing a Kerr nonlinearity that is accompanied by a two-photon absorptive loss. Because of their usefulness in diagnostics, we obtain expressions for the pump amplitude within the cavity, the reflection coefficient for the pump amplitude reflected off of the cavity, the parametric gain, and the intermodulation gain. Expressions by which of the degree of squeezing can be computed are also presented.
