description: This paper addresses the amplitude and phase dynamics of a large system non-linear coupled, non-identical damped harmonic oscillators, which is based on recent research in coupled oscillation in optomechanics. Our goal is to investigate the existence and stability of collective behaviour which occurs due to a play-off between the distribution of individual oscillator frequency and the type of nonlinear coupling. We show that this system exhibits synchronisation, where all oscillators are rotating at the same rate, and that in the synchronised state the system has a regular structure related to the distribution of the frequencies of the individual oscillators. Using a geometric description we show how changes in the non-linear coupling function can cause pitchfork and saddle-node bifurcations which create or destroy stable and unstable synchronised solutions. We apply these results to show how in-phase and anti-phase solutions are created in a system with a bi-modal distribution of frequencies.

description: We report on observations of recurrent jets by instruments onboard the Interface Region Imaging Spectrograph (IRIS), Solar Dynamics Observatory (SDO) and Hinode spacecrafts. Over a 4-hour period on July 21st 2013, recurrent coronal jets were observed to emanate from NOAA Active Region 11793. FUV spectra probing plasma at transition region temperatures show evidence of oppositely directed flows with components reaching Doppler velocities of +/- 100 km/s. Raster Doppler maps using a Si IV transition region line show all four jets to have helical motion of the same sense. Simultaneous observations of the region by SDO and Hinode show that the jets emanate from a source region comprising a pore embedded in the interior of a supergranule. The parasitic pore has opposite polarity flux compared to the surrounding network field. This leads to a spine-fan magnetic topology in the coronal field that is amenable to jet formation. Time-dependent data-driven simulations are used to investigate the underlying drivers for the jets. These numerical experiments show that the emergence of current-carrying magnetic field in the vicinity of the pore supplies the magnetic twist needed for recurrent helical jet formation.

description: We report 7Li-NMR studies on LiInCr4O8 and LiGaCr4O8, in which Cr3+ ions with spin 3/2 form a breathing pyrochlore lattice, a network of tetrahedra with alternating sizes. In LiInCr4O8 with large alternation, the nuclear relaxation rate 1/T1 shows an activated temperature (T) dependence down to 18 K, indicating a singlet ground state with a spin gap. This behavior, however, is disrupted by an antiferromagnetic (AF) transition at 13 K, which is preceded by another, most likely structural, transition at 16 K. In contrast, LiGaCr4O8 with small alternation shows no spin gap but exhibits a first-order AF transition over a distributed T-range 13-20 K. Nevertheless, 1/T1 of the paramagnetic phase diverges toward 13 K, indicating proximity to a second-order transition. The results indicate that LiGaCr4O8 is located in the vicinity of a tricritical point in the phase diagram.

description: Computer vision has a great potential to help our daily lives by searching for lost keys, watering flowers or reminding us to take a pill. To succeed with such tasks, computer visionmethods need to be trained from real and diverse examples of our daily dynamic scenes. First, we need to give computers insight into our world, and our daily lives. Not just through the charade the we present to the world on social media, but through a genuine look at the most boring, mundane, routine aspects of our lives. But how do we model this data? How do we model information over time? How do we harness the richness and complexity of this data to enable understanding? To provide a lens through which to look at humans in their mundane lives, we exploredtechniques for crowdsourcing the creation of this data from hundreds of people in their own homes, and analyzed how humans think about activities along with the best strategiesfor annotating complex data of this nature. Given this insight into human behaviour, we can start understanding where other vision techniques have trouble, understand how toimprove them, and which venues are most promising moving forward. Once we have this kind of data, we can start building algorithms that harness the unique aspects of this data by learning how human activities change over time, and what activities occur with a recognizable temporal structure. We can harness the data to learn how complete human events generally unfold, such as a snowboarding trip, and apply these models to applied problems such as summarizing photo albums. Finally, we combine ideas from our work to demonstrate how these techniques can be used to collect data and modeling human activities from first and third-person at the same time, and unsupervised concept learning from web videos. We hope this kind of realistic bias may provide new insights that aid robots equipped with our computer vision models operating in the real world.

description: We demonstrate that superconductors which break time-reversal symmetry can exhibit thermoelectric properties, which are entirely different from the Ginzburg mechanism. As an example, we show that in the $s+is$ superconducting state there is a reversible contribution to thermally induced supercurrent, whose direction is not invariant under time-reversal operation. Moreover in contrast to Ginzburg's mechanism it has a singular behavior near the time-reversal symmetry breaking phase transition. The effect can be used to confirm or rule out the $s+is$ state, which is widely expected to be realized in pnictide compounds Ba$_{1-x}$K$_{x}$Fe$_2$As$_2$ and stoichiometric LiFeAs.

description: El envejecimiento poblacional tiene un gran impacto en los servicios de salud por ello la disponibilidad suficiente de recursos, financieros y materiales para su atención constituye un elemento esencial. Este es un escenario de importantes desafíos para la familia, la interacción comunitaria, el estado y la sociedad. Ello demanda ampliar y reorientar los programas sociales, sectoriales, de bienestar y salud. La presente investigación pretende determinar la disponibilidad de los recursos humanos, financieros y materiales para la atención a las personas mayores en el Área II, del Municipio Cienfuegos, durante el año 2018. Con este propósito los autores conducen un estudio descriptivo de corte transversal en el que se aborda la disponibilidad de recursos humanos, financieros y materiales para la atención al adulto mayor que reside en dicho sector geográfico. Para cumplir los objetivos propuestos se llevó a cabo una revisión bibliográfica del tema y de documentos primarios del Área de Salud en cuestión. Fue aplicado un conjunto de instrumentos estadístico, entre los que se encuentran cuestionarios y entrevistas al personal de salud y los adultos mayores que son objeto de atención por parte de la entidad de salud, así como instrumentos de observación encubierta en diferentes servicios de salud y consultorios. Con posterioridad, Los datos estadísticos adquiridos fueron procesados con el programa Microsoft Excel del paquete de Microsoft Office. La interpretación de la información resultante permitió determinar que la percepción sobre la calidad de la atención se encontraba entre buena (47.1) y regular (44.3), lo que evidenció insatisfacción y la presencia de brechas entre los recursos humanos, financieros y materiales existentes en la atención a este grupo etario. Pudo constatarse la no realización de controles médicos, lo cual originaba que los pacientes solo se chequearan cuando estaban enfermos. No se realizaban visitas de terreno, este grupo carecía de prioridad en los servicios de salud y recibía la misma atención que el adulto joven. El estudio evidenció sobrecarga en el trabajo de las Enfermeras y los Fisiatras, a pesar de haber plazas vacantes de médicos y de enfermeras. Algunas especialidades mostraban un elevado número de pacientes con un tiempo de espera muy elevado.

description: The readout fidelity of superconducting transmon and Xmon qubits is partially limited by the qubit energy relaxation through the resonator into the transmission line, which is also known as the Purcell effect. One way to suppress this energy relaxation is to employ a filter which impedes microwave propagation at the qubit frequency. We present semiclassical and quantum analyses for the bandpass Purcell filter realized by E.\ Jeffrey \textit{et al}.\ [Phys.\ Rev.\ Lett.\ 112, 190504 (2014)]. For typical experimental parameters, the bandpass filter suppresses the qubit relaxation rate by up to two orders of magnitude while maintaining the same measurement rate. We also show that in the presence of a microwave drive the qubit relaxation rate further decreases with increasing drive strength.

description: Workplace mistreatment, defined as interpersonal conduct aimed at causing harm to another employee (Bowling & Beehr, 2006), has attracted the attention of researchers due to its wide range of negative repercussions. Workplace mistreatment includes a spectrum of deviant behaviours, such as incivility, verbal aggression and bullying, that vary in degree and intent. Andersson and Pearson (1999) defined workplace incivility as mildly disrespectful behaviours in which the intent to do harm to another person is uncertain. Extensive research has examined workplace incivility as a social stressor. However, little is known about the differential effects of insider and outsider sources of this deviant behaviour on well-being. This is significant because the impact of incivility may vary depending on the source. Thus, this research examined the differential impact of experienced incivility from people both within and external to the organisation on employee well-being. Furthermore, this research aimed to advance our understanding of how individual differences in personal resources can mitigate the negative relationship between different sources of incivility and well-being. To address these research questions, I conducted two time-lagged studies in two distinct contexts (hospitals, schools) characterised by chronically low job resources and where employees interact with a variety of individuals within and outside the organisation. Study 1 investigated the impact of mistreatment experienced by healthcare employees from other colleagues (insiders) and patients and visitors (outsiders). The findings showed that insider mistreatment predicted affective ill-being a week later, whereas outsider mistreatment did not. Additionally, self-efficacy moderated the relationship between insider mistreatment with affective ill-being. Study 2 replicated Study 1 in a teaching context to determine if the results replicate for another working population. The findings demonstrated that incivility from colleague (insiders) and students’ parents (outsiders) predicted burnout two weeks later. Resilience moderated the relationship between insider incivility and burnout. Altogether, the studies highlighted that mistreatment, such as incivility, negatively impacted well-being. Additionally, the two studies indicated that personal resources may not always mitigate this relationship but can in fact exacerbate them. These results suggested that experiencing incivility was distressing for people high on either self-efficacy or resilience. This could be due to the cognitive effort required to understand why they were treated such and the high expectations of maintaining professionalism at work.

description: On research and development, India spends just 1 percent of its Gross Domestic Product (GDP) with almost up to eighty percent (80%)t of that money comes from Indian government. whereas almost 75 percent of research related money in developed countries come from thenon government / private sector. [1] In the developed and innovative countries, the private sectors have constant collaboration with academic institutions for research, each giving the advantages to the other one. Though, India is also having these kinds of collaborations, but it is on a very small level. [2] Considering the US pharmaceutical sector, largely based on innovative companies, makes a direct output of about $461,000 US Dollars per employee.. The European pharmaceutical sector contributed an international level trade surplus of 54 billion US Dollars. It shows that the western countries consider these industries as big economic assets. [3] India is also having a good potential to grow its innovative pharmaceutical sector. As India is having a developed scientific base and a pool of highly skilled scientists and researchers. India is one of the top ten ‘most bio-diverse’ countries. Also India is having large coastline marine organisms that could provide a suitable resource for drug research. [4] Indian pharma sector has capacity to florish because of its resources and capabilities. This article tries to investigate some of the innovative developments in the field of Indian pharmaceutical sector. At the same time, we have tried to summaries some of challenges for the Indian pharmaceutical industry in the pursuit of these goals.

description: Recently, 'Cipla Ltd.' which is one of a top pharmaceutical companies of India, has requested the government of India to improve ease of doing business, increase expenditure in the healthcare sector and formulate a pharmaceutical policy that aids the pharmaceutical industry of India. The Chairman of Cipla said that basic healthcare in India will always want urgent attention, Considering the country's population and disease. [1] Apart from above, one needs only to look at the $16-billion pharmaceutical sector to understand how India makes its difficult in the Ease of Doing Business. India is already in the news for a controversial ban on several household medicines. [2] Also recently, the health ministry has requested the pharma industry to provide information regarding the permissions needed from various agencies and the time taken by agencies to get them. According to the drug controller, it's time the industry needs to come up with suggestions on how government can come up with solutions to make growth supportive atmosphere. [3] In this research paper we are going to have a look on current status of ease of doing business in India for pharmaceutical companies as well as government's initiatives to find solutions to make 'growth supportive' atmosphere for pharmaceutical business. Also, we will evaluate the suggestions given by top pharmaceutical companies to government in this regards.

description: The paper estimates the political connection premium for Italian cities tracked during the second half of the 1900s, when the role of the state in the economy was very widespread. It leverages the peculiar features of the gridlocked political landscape in place between the end of World War II and the fall of the Berlin wall, during which most influential politicians remained in charge for a very long time. We compare connected cities - small areas surrounding birthplaces of both prime ministers and leaders of the parties in power - with very similar, but unconnected municipalities, and find that politically connected cities gained a population premium of 8% over 40 years. When the connection ends, the difference in growth rate fades away. We document that birthplaces of powerful politicians benefited from both infrastructure investments and the location of plants by state-owned enterprises. Not surprisingly, the connection favored industrialization, raised employment and wages, but crowded out private entrepreneurship. Finally, our empirical evidence indicates that agglomeration economies in treated municipalities were not higher, thus suggesting that, if anything, place-based interventions linked to political connections have not been output-enhancing from a nationwide point of view.

description: Harmful cyanobacterial blooms represent an increasing threat to freshwater resources globally. Despite increased research, the physiological basis of how the dominant bloom-forming cyanobacteria, Microcystis spp., proliferate and then maintain high population densities through changing environmental conditions is poorly understood. In this study, we examined the transcriptional profiles of the microbial community in Lake Taihu, China at 9 stations sampled monthly from June to October in 2014. To target Microcystis populations, we collected metatranscriptomic data and mapped reads to the M. aeruginosa NIES 843 genome. Our results revealed significant temporal gene expression patterns, with many genes separating into either early or late bloom clusters. About one-third of genes observed from M. aeruginosa were differentially expressed between these two clusters. Conductivity and nutrient availability appeared to be the environmental factors most strongly associated with these temporal gene expression shifts. Compared with the early bloom season (June and July), genes involved in N and P transport, energy metabolism, translation, and amino acid biosynthesis were down-regulated during the later season (August to October). In parallel, genes involved in regulatory functions as well as transposases and the production of microcystin and extracellular polysaccharides were up-regulated in the later season. Our observation indicates an eco-physiological shift occurs within the Microcystis spp. transcriptome as cells move from the rapid growth of early summer to bloom maintenance in late summer and autumn.

description: In condensed matter physics the quasi two-dimensional electron gas at the interface of two different insulators, polar LaAlO3 on non-polar SrTiO3 (LaAlO3/SrTiO3) is a spectacular and surprising observation. This phenomenon is LaAlO3 film thickness-dependent and may be explained by the polarization catastrophe model, in which a charge transfer of 0.5 electron from the LaAlO3 film into the LaAlO3/SrTiO3 interface is expected. Here we show that in conducting samples (more than 4 unit cells of LaAlO3) there is indeed a 0.5 electron transfer from LaAlO3 into the LaAlO3/SrTiO3 interface by studying the optical conductivity in a broad energy range (0.5-35 eV). Surprisingly, in insulating samples (less than 4 unit cells of LaAlO3) a redistribution of charges within the polar LaAlO3 sub-layers (from AlO2 to LaO) as large as 0.5 electron is observed, with no charge transfer into the interface. Hence, our results reveal the different mechanisms for the polarization catastrophe compensation in insulating and conducting LaAlO3/SrTiO3 interfaces.

Mitigating the Expansion of Harmful Algal Blooms Across the Freshwater-to-Marine Continuum

description: Anthropogenic nutrient overenrichment, coupled with rising temperatures, and an increasing frequency of extreme hydrologic events (storms and droughts) are accelerating eutrophication and promoting the expansion of harmful algal blooms (HABs) across the freshwater-to-marine continuum. All HABs - with a focus here on cyanobacterial blooms - pose serious consequences for water supplies, fisheries, recreational uses, tourism, and property values. As nutrient loads grow in watersheds, they begin to compound the effects of legacy stores. This has led to a paradigm shift in our understanding of how nutrients control eutrophication and blooms. Phosphorus (P) reductions have been traditionally prescribed exclusively for freshwater systems, while nitrogen (N) reductions were mainly stressed for brackish and coastal waters. However, because most systems are hydrologically interconnected, single nutrient (e.g., P only) reductions upstream may not necessarily reduce HAB impacts downstream. Reducing both N and P inputs is the only viable nutrient management solution for long-term control of HABs along the continuum. This article highlights where paired physical, chemical, or biological controls may improve beneficial uses in the short term, and offers management strategies that should be enacted across watershed scales to combat the global expansion of HABs across geographically broad freshwater-to-marine continua.

Intelligent Locomotion Planning with Enhanced Postural Stability for Lower-Limb Exoskeletons
Creators: Javad K. Mehr, Mojtaba Sharifi, Vivian K. Mushahwar, Mahdi Tavakoli
Publisher: name: University of Alberta Library
Year: 2021

In this paper, an integrated control strategy is developed for both locomotion trajectory planning and postural stability, enabling shared autonomy between the human and lower-limb exoskeleton. Divergent component of motion (DCM) analysis was employed previously based on the linear inverted pendulum flywheel (LIPF) model to regulate the position of the center of mass (CoM) for humanoid robots. In this study, a new extended model is investigated for the DCM analysis by replacing the previous LIPF model, which is tailored for multi-degree-of-freedom (DOF) exoskeletons. This new model is designed to be personalized for each specific user’s body by relaxing the assumption of having the total CoM at the hip joint

in the previous LIPF model. Accordingly, the exoskeleton has the authority to ensure the postural stability and viability of locomotion in this human-robot interaction (HRI) by adjusting the upper body position using a DCM-based hip correction strategy. Integrating adaptive central pattern generators (CPGs), the human has enough authority to modify the gait trajectories in real-time, while the amplitude and frequency of walking are

constrained to their feasible ranges. The effectiveness of this intelligent controller for safe and stable locomotion is investigated through experimental studies on a lower-limb exoskeleton.

description: We study the isoscalar and isovector $J=0,1$ mesons with the overlap operator within two flavour lattice QCD. After subtraction of the lowest-lying Dirac eigenmodes from the valence quark propagator all disconnected contributions vanish and all possible point-to-point $J=0$ correlators become identical, signaling a simultaneous restoration of both $SU(2)_L \times SU(2)_R$ and $U(1)_A$ symmetries. The ground states of the $π,σ,a_0,η$ mesons do not survive this truncation. All possible $J=1$ states have a very clean exponential decay and become degenerate, demonstrating a $SU(4)$ symmetry of a dynamical QCD-like string.

description: The axial length of the eye is critical for normal visual function by enabling light to precisely focus on the retina. The mean axial length of the adult human eye is 23.5 mm, but the molecular mechanisms regulating ocular axial length remain poorly understood. Underdevelopment can lead to microphthalmia (defined as a small eye with an axial length of less than 19 mm at 1 year of age or less than 21 mm in adulthood) within the first trimester of pregnancy. However, continued overgrowth can lead to axial high myopia (an enlarged eye with an axial length of 26.5 mm or more) at any age. Both conditions show high genetic and phenotypic heterogeneity associated with significant visual morbidity worldwide. More than 90 genes can contribute to microphthalmia, and several hundred genes are associated with myopia, yet diagnostic yields are low. Crucially, the genetic pathways underpinning the specification of eye size are only now being discovered, with evidence suggesting that shared molecular pathways regulate under- or overgrowth of the eye. Improving our mechanistic understanding of axial length determination will help better inform us of genotype-phenotype correlations in both microphthalmia and myopia, dissect gene-environment interactions in myopia, and develop postnatal therapies that may influence overall eye growth.

description: Reactor designs with mixed catalysts play an important role transforming a multiple reactor system to single-shot reactors. In addition to savings in capital and ease of implementation, single-shot reactors are useful to break equilibrium limitations, therefore increasing the yield and selectivity of desired product as shown in literature. However, the nonlinear and highly exothermic nature of mixed-catalyst systems makes it difficult for commercial process simulation and optimization tools to optimize these systems. This study describes the development and application of optimization strategies for mixed-catalyst, single-shot reactors for syngas-to-olefin processes. Finding the optimal catalyst distribution is challenging and requires advanced solution strategies for singular optimal control problems, which are poorly conditioned and often lead to flat response surfaces. The graded bed and partial moving finite element approaches are used to find the optimal catalyst distribution that maximizes the olefins yield. 1.3 % increase in the yield is observed from 1 zone to 3 zones. The yield further improves from 3 zone to the exact solution by 0.2%. This improvement can be achieved by changing only the catalyst distribution, without any extra investment. To account for the uncertainty in kinetic parameters, a two-stage multi-scenario problem formulation is implemented, and a robust reactor design is achieved. The robust design guarantees the desired olefins to paraffins ratio in the reactor, even for the worst set of kinetic parameters. The aim of this study is to come up with an optimization framework that can solve mixed catalyst reactive systems, which have singular characteristics that can cause numerical instabilities. Also, thermal runaway constraints are embedded into the optimization formulation for a safe operation. Finally, the robust design handles the uncertain parameters. This framework is applied to syngas-to-olefins reaction network and can be easily extended to other mixed-catalyst reactive systems.
Mitigating toxic planktonic cyanobacterial blooms in aquatic ecosystems facing increasing anthropogenic and climatic pressures
Creators: name: Paerl, H.W.
Publisher: name: MDPI AG
Year: 2018

description: Toxic planktonic cyanobacterial blooms are a pressing environmental and human health problem. Blooms are expanding globally and threatening sustainability of our aquatic resources. Anthropogenic nutrient enrichment and hydrological modifications, including water diversions and reservoir construction, are major drivers of bloom expansion. Climatic change, i.e., warming, more extreme rainfall events, and droughts, act synergistically with human drivers to exacerbate the problem. Bloom mitigation steps, which are the focus of this review, must consider these dynamic interactive factors in order to be successful in the short- and long-term. Furthermore, these steps must be applicable along the freshwater to marine continuum connecting streams, lakes, rivers, estuarine, and coastal waters. There is an array of physical, chemical, and biological approaches, including flushing, mixing, dredging, application of algaecides, precipitating phosphorus, and selective grazing, that may arrest and reduce bloom intensities in the short-term. However, to ensure long term, sustainable success, targeting reductions of both nitrogen and phosphorus inputs should accompany these approaches along the continuum. Lastly, these strategies should accommodate climatic variability and change, which will likely modulate and alter nutrient-bloom thresholds.

description: We present evidence for collective action of Cr$^{3+}$ ion impurities in a highly doped ruby crystal at microwave frequencies. The cylindrical geometry of the crystal allows for the creation of a superradiant, or "spin-mode" doublet, with spatial structure similar to that of microwave whispering gallery modes (WGMs). This results in a strict criteria of selection rules regarding the interaction of resonant WGMs and spin-modes; namely that only modes with the same wavenumber and azimuthal phase may interact. What results is an avoided level crossing between the two, in which both WGM doublet constituents are seen to interact with the spin resonance. We demonstrate that a four harmonic oscillator model is necessary to accurately describe this result.

description: Highly automated/autonomous vehicles using extended features like Vehicle to Vehicle (V2V) or Vehicle to Infrastructure (V2I), cognitive systems for decision taking, needing extensive perception features and sophisticated sensor functions, cause a considerable shift in safety and cybersecurity (trustworthiness) co-engineering and assurance. To achieve trust of the public/users, standards and cer-tification/qualification are challenged, not comparable to conventional “singular vehicle only” issues. The paper highlights the necessary evolution in the automo-tive and related standardization landscape, including ethics guidelines and recent activities, and the consequences from upcoming UNECE (United Nations Eco-nomic Comission for Europe) regulations. An Overview on ongoing work in large European ECSEL projects, SECREDAS and AutoDrive, including standardiza-tion, is provided.
On the origin of the absorption and emission line components in the spectra of PHL 293B

description: From the structure of PHL 293B and the physical properties of its ionizing cluster and based on results of hydrodynamic models, we point at the various events required to explain in detail the emission and absorption components seen in its optical spectrum. We ascribe the narrow and well centered emission lines, showing the low metallicity of the galaxy, to an HII region that spans through the main body of the galaxy. The broad emission line components are due to two off-centered supernova remnants evolving within the ionizing cluster volume and the absorption line profiles are due to a stationary cluster wind able to recombine at a close distance from the cluster surface, as originally suggested by Silich et al. (2004). Our numerical models and analytical estimates confirm the ionized and neutral column density values and the inferred X-ray emission derived from the observations.

Measurements of the ZZ production cross sections in the 2 l 2 nu channel in proton-proton collisions at sqrt(s) = 7 and 8 TeV and combined constraints on triple gauge couplings

description: Measurements of the ZZ production cross sections in proton-proton collisions at center-of-mass energies of 7 and 8 TeV are presented. Candidate events for the leptonic decay mode ZZ to 2 l 2 nu, where l denotes an electron or a muon, are reconstructed and selected from data corresponding to an integrated luminosity of 5.1 (19.6) inverse femtobarns at 7 (8) TeV collected with the CMS experiment. The measured cross sections, sigma(pp to ZZ) = 5.1 -1.4 +1.5 (stat) -1.1 +1.4 (syst) +/- 0.1 (lumi) pb at 7 TeV, and 7.2 -0.8 +0.8 (stat.) -1.5 +1.9 (syst) +/- 0.2 (lumi) pb at 8 TeV, are in good agreement with the standard model predictions with next-to-leading-order accuracy. The selected data are analyzed to search for anomalous triple gauge couplings involving the ZZ final state. In the absence of any deviation from the standard model predictions, limits are set on the relevant parameters. These limits are then combined with the previously published CMS results for ZZ in 4 l final states, yielding the most stringent constraints on the anomalous couplings.

Quantifying Mechanical Behavior and Coherence of Epithelial Cell Monolayers
Creators: name: Lavrenyuk, Kirill
Publisher: name: Carnegie Mellon University

Subjects: Biophysics

description: Cells generate forces as a means of interacting with their environment, including other cellular partners. Further, cells are sensitive to mechanical changes which often alter force generation or transmission. Mis-regulation of signaling in mechanosensitive pathways results in a variety of defects or diseases, including many epithelial cell cancers. Understanding the transmission of force within epithelial cells is crucial to addressing diseased states, and delineating the downstream impacts on important phenomenon such as contact inhibition of proliferation, cell fate determination, and apoptosis. Single epithelial cells primarily exert tensile by pulling against the extracellular basal substrate via focal adhesion. However, as epithelial cells grow into monolayers, the emergence of cell-cell junctions interconnects cytoskeletal structures between cells and fundamentally alters force transmission across the cellular landscape and the cellular colony. In this work, I specifically probe transmission of force throughout the cell, the peripheral E-cadherin junctions and fully internalized at the nucleus and chromatin. Using engineering proteins at key regions in the cell, I tracked the transduction of force and the impact on chromatin energetics deep within the nucleus showing that despite the dynamic nature of the cytoskeleton, there is still mechanical integration from the plasma membrane to the chromatin. Importantly, epithelial cells attain mechanical coherence as the monolayer matures, reaching a homeostatic energy state for the monolayer. Often, treatments that modulate the ability of the cytoskeleton to generate force result in concomitant energetic changes derived from the motion of chromatin. Thus, mechanical integration that spans a single cell is also present in the cell collective, shedding new light on the poorly elucidated behaviors of epithelial cell monolayers.
Physical limit to concentration sensing amid spurious ligands

description: To adapt their behaviour in changing environments, cells sense concentrations by binding external ligands to their receptors. However, incorrect ligands may bind nonspecifically to receptors, and when their concentration is large, this binding activity may interfere with the sensing of the ligand of interest. Here, I derive analytically the physical limit to the accuracy of concentration sensing amid a large number of interfering ligands. A scaling transition is found when the mean bound time of correct ligands is twice that of incorrect ligands. I discuss how the physical bound can be approached by a cascade of receptor states generalizing kinetic proof-reading schemes.

description: We study the light matter interaction in WS$_{2}$ nanotube-graphene hybrid devices. Using scanning photocurrent microscopy we find that by engineering graphene electrodes for WS$_{2}$ nanotubes we can improve the collection of photogenerated carriers. We observe inhomogeneous spatial photocurrent response with an external quantum efficiency of $\sim 1\%$ at 0 V bias. We show that defects play an important role and can be utilized to enhance and tune photocarrier generation.
