Cold stress inhibits photosynthesis in the coral model Exaiptasia pallida

Extreme changes in sea surface temperatures driven by climate change are the result of continuous anthropogenic activities increasing carbon dioxide concentrations in the atmosphere. Varying temperatures lead to coral bleaching, a process by which cnidarian hosts expel their endosymbiotic algae, rendering the host susceptible to disease or death. In response to bleaching, cnidarians must rely more heavily on their ability to capture food, rather than photosynthates from their symbionts. Vice versa, during food scarcity, cnidarians rely on their symbiont’s photosynthetic ability to provide food. While the effects of temperature stress on cnidarians are well studied, the combined effects of thermal and food stress are not well known. Here, we consider the effects of both heat and cold thermal stress along with different feeding regimes on the host and symbiont of the anemone ​Exaiptasia pallida, ​a common model organism. ​E. pallida were exposed to three temperature treatments: cold (18​o​-1​o​C/day), hot (18​o​+1​o​C/day), and ambient (18​o​) for 14 days. Within each temperature treatment, individuals were divided into two feeding regimes: fed and starved. Symbiont photosynthetic efficiency (Fv/Fm) was measured using pulse amplitude modulation (PAM), while chlorophyll concentration was determined using photograph-derived intensity in the red channel (IRC). Host physiology was assessed using pedal disk diameter measurements and mortality observations. Cold stress reduced symbiont photosynthetic efficiency, pedal diameter, and intensity in the red channel. However, feeding regimes had no influence on the form or function of the holobiont. As climate change continues to progress and temperatures shift beyond cnidarians’ typical range, understanding how they respond to both cold and hot thermal stress is imperative to assess future survivability. Introduction The symbiotic relationship between cnidarians and their algal symbionts (​Symbiodiniaceae​) is essential for the maintenance of tropical coral reef ecosystems (Davy and Cook, 2001). The coral host provides structure and inorganic materials required for the algal symbiont to photosynthesize, while the symbiont provides photosynthetically-derived carbon sugars to the host (​Rosenberg et al., 2007). Photosynthetic efficiency of symbionts can be decreased by photoinhibition in photosystem II, which is often caused by environmental stressors including temperature (​Takahashi et al., 2009)​. Elevated sea surface temperatures, which are increasing in frequency with climate change, cause a disruption between the endosymbiosis of cnidarians and their Symbiodiniaceae ​(Wild et al., 2011). Coral bleaching is the common response to these changes in temperature, as it is a process by which the coral or other cnidarian hosts
Analysts and clients in organisations: a conversational view

This paper takes a conversational perspective on the issue of analyst–client interaction, concentrating on how social and organisational contexts impact on the verbal process of defining a new information system. It has been suggested that organisational agendas are built from talk at the interactional level (Boden, 1994), and this paper seeks to explore the relationship between social and organisational contexts and the process of early requirements gathering. Analysts and clients were asked about their aims, their professional role, and other issues that arose in their interactions with each other as part of a larger study in early requirements gathering. The paper discusses three themes from three case studies that can be seen to be embedded in the social and organisational context of early requirements gathering—how the issues to be discussed during the interaction were put forward, professional relationships, and the overall organisational context in which the interaction takes place. Some observations are made about the varying social and organisational contexts of early requirements gathering and the role of individual differences, and the possibility of using typical contexts as ‘repertoire building research’ (Schon, 1983) to flow into practice.

Wittgenstein’s remarks on Gödel’s first incompleteness theorem often have been denounced: Kreisel calls them “wild,” Dummett has insisted that they “are of poor quality and contain definite errors,”Wright discreetly fails to mention them in his book onWittgenstein’s philosophy of mathematics. Gödel himself claimed that Wittgenstein had not understood the theorem, or at least had “pretended not to. ” On the contrary, I argue that Wittgenstein did understand the theorem, that he had no interest in trying to refute it, and that in fact he appropriated it for his own philosophical purposes.

Tax Footnotes Readability and CEO Narcissism: Evidence from Indonesia

CEO Narcissism has the potency to influence individual characteristics positively or negatively. We aim to examine the relationship between narcissism as CEO-level characteristics and tax footnotes readability. We measure narcissism using the CEOs’ photos on the firms’ annual reports. Using 799 firm-year Indonesia listed firms from 2015 through 2019, we find that higher CEO narcissism is related to a higher tax footnote readability. This result is robust for alternative measures of readability. By examining the relationship between CEO narcissism and tax footnotes readability, we provide an additional important factor to boards for consideration during the CEO selection. We also offer insight for shareholders or investors to consider CEO traits, namely narcissism, in assessing and interpreting tax footnotes readability.
A survey on smart phone-based road condition detection systems

With the advancement in technology, Intelligent Transportation Systems (ITS) aims to maximize the safety and convenience of the transportation system. It focuses on the integration of technology into the traditional transportation structure for future smart cities. With the proliferation of the road network in all nations across the world, road surface condition data has become a critical component in reducing road accidents. Road condition monitoring is an important part of transportation management and affects the safety of the commute. Different methods based on manual, automatic, and semi-automatic monitoring of road conditions have been proposed in the literature. In this paper, we present a survey of smartphone-based road condition monitoring techniques. The data is acquired using smartphones and the algorithms discussed detect the road anomalies like manholes, speed bumps, potholes, and cracks, etc. A comparative analysis has been carried out based on the benefits, drawbacks, and methods used by various techniques. Furthermore, new research directions for smartphone-based detection of road surface anomalies have been presented.
The Convenient Disregard for the Rattus Species in the Laboratory Environment: Implications for Animal Welfare and Science

Abstract:This article encourages a rethinking of how rats are regarded within the laboratory research environment. The rat's remarkable intellect and cognitive capacities are well known yet conveniently ignored. An understanding of the five domains of animal welfare and the telos of the rat necessitate that the rat's circumstances, namely habitat accommodations, in the research arena be reassessed. The rat-ness of being a rat must be considered, celebrated, and elevated to significantly higher standards. We advocate for a new research paradigm if one continues to "use" the extraordinary Rattus species.
ACCESSIBILITY AND UTILIZATION OF INTERNET SERVICE IN NIGERIA LIBRARIES: AN EMPIRICAL STUDY

Recently certified librarians are revolutionizing the library profession by collaborating with peers and colleagues from all ages to make things happen. This paper investigates certified librarians perception on accessibility and utilization of internet service in Nigeria libraries. The design of the study is cross sectional survey and the population consists of 364, 1st Conference of Certified Librarians by Librarians’ Registration Council of Nigeria (LRCN) held in 2014.The instrument used to generate data is the questionnaire and the data generated was analyzed using frequency, bar charts, table, percentages and mean. The outcome of the study reveals that majority of the participants were from academic library asserted that internet was very accessible to them. Whereas some libraries indicated that internet was not accessible to them at all. It also found that the participants strongly agreed that the reasons for which staff used the internet in Nigeria libraries are for research purpose, for current awareness services/ update of knowledge and to develop personal competencies among other. It also revealed that, lack of search skills, information overload, power outage, irrelevant information, difficulties in navigation of website, inaccessibility of some sites and unavailability/ inaccessibility of the internet services were some of the challenges faced by the staff in Nigeria libraries.
A Machine‐Learning‐Assisted Stochastic Cloud Population Model as a Parameterization of Cumulus Convection

A machine‐learning‐assisted stochastic cloud population model is coupled with the Advanced Research Weather Research and Forecasting (WRF) model to represent fluctuations in the cloud‐base mass flux associated with the life cycles and interactions among cumulus convection cells. In this cloud population model, the size distribution and the associated cloud‐base mass flux of the convective cells are related to their previous state and to the change in the total convective area via a transition function. The convective area tendency in turn is assumed to depend on the cloud‐base mass flux that is resolved by the host WRF model. The transition function is represented by a single hidden‐layer neural network trained by the evolution of convective cell size distributions in a 1‐km grid‐spacing WRF simulation run over the Australian Monsoon region. At every grid point of the host model, the cloud population model predicts the cell size and cloud‐base mass flux distributions from which a random sample of cells is fed to an entraining parcel model that calculates precipitation as well as the associated liquid water potential temperature and total moisture tendencies. These tendencies are averaged over the cells and provided to the host model. Several regional simulations are performed over tropical and midlatitude domains to test this as a potential approach to scale‐aware parameterization. It is shown that such an approach could be a new promising path to simulating realistic precipitation statistics and propagation of precipitation associated with the Madden‐Julian Oscillation while maintaining realistic depictions of the diurnal cycle over both land and ocean.
Process-Induced Delay Variation in SWCNT, MWCNT, and Mixed CNT Interconnects

ABSTRACT This paper deals with an analysis of propagation delay in carbon nanotube (CNT) bundled interconnects under process-induced variations. An accurate and compact analytical model of mixed CNT bundle (MCB) is employed that takes into account the random distribution of CNTs having different diameters. Depending on the bundle configurations, a multi-conductor transmission line (MTL) model is presented for MCB, bundled SWCNT, and bundled MWCNT interconnects. The performance of CNT bundles is investigated under process-induced variations of temperature, metallic ratio, contact resistance, and bundle area. A driver-interconnect-load (DIL) system is used to perform the Monte Carlo simulations to analyze the impact of process-induced variations on propagation delay. It is observed that the MCB is more tolerant to the process variations for global interconnect lengths with respect to the bundled SWCNT and bundled MWCNT.
Curvelet Transform-Based Sparsity Promoting Algorithm for Fast Ultrasound Localization Microscopy

Ultrasound localization microscopy (ULM) based on microbubble (MB) localization was recently introduced to overcome the resolution limit of conventional ultrasound. However, ULM is currently challenged by the requirement for long data acquisition times to accumulate adequate MB events to fully reconstruct vasculature. In this study, we present a curvelet transform-based sparsity promoting (CTSP) algorithm that improves ULM imaging speed by recovering missing MB localization signal from data with very short acquisition times. CTSP was first validated in a simulated microvessel model, followed by the chicken embryo chorioallantoic membrane (CAM), and finally, in the mouse brain. In the simulated microvessel study, CTSP robustly recovered the vessel model to achieve an 86.94% vessel filling percentage from a corrupted image with only 4.78% of the true vessel pixels. In the chicken embryo CAM study, CTSP effectively recovered the missing MB signal within the vasculature, leading to marked improvement in ULM imaging quality with a very short data acquisition. Taking the optical image as reference, the vessel filling percentage increased from 2.7% to 42.2% using 50ms of data acquisition after applying CTSP. CTSP used 80% less time to achieve the same 90% maximum saturation level as compared with conventional MB localization. We also applied CTSP on the microvessel flow speed maps and found that CTSP was able to use only 1.6s of microbubble data to recover flow speed images that have similar qualities as those constructed using 33.6s of data. In the mouse brain study, CTSP was able to reconstruct the majority of the cerebral vasculature using 1-2s of data acquisition. Additionally, CTSP only needed 3.2s of microbubble data to generate flow velocity maps that are comparable to those using 129.6s of data. These results suggest that CTSP can facilitate fast and robust ULM imaging especially under the circumstances of inadequate microbubble localizations.
Self-consistent simulation of multi-walled CNT nanotransistors

We present detailed results of the self-consistent analysis of carbon nanotube (CNT) field-effect transistors (FET), previously extended by us to the case of multi-walled/multi-band coherent carrier transport. The contribution to charge transport, due to different walls and sub-bands of a multi-walled CNT, is shown to be generally non-negligible. In order to prove the effectiveness of our simulation tool, we provide interesting examples about current–voltage characteristics of four-walled semi-conducting nanotubes, including details of numerical convergence and contribution of sub-bands to the calculation.
Implementation of a Modelica Library for Simulation of High-Lift Drive Systems

The development and design of new high-lift drive systems is a complex and iterative process, which is often depending on experience. Especially results determined in the predevelopment phase and based on uncertain assumptions have decisive influence on the system specification and thus on the system design. In order to reduce development time and optimize the development process, a rapid generation and adaptation of simulation models for analysis of transient system behaviour is essential. This article presents an computer-integrated approach for further reduction of the high-lift development process. An interface to Modelia should enable an automated system model generation. A suitable component library is introduced and verified by simulation of the Airbus A380 flap actuation system. The purpose of this article is to present the project of a computer-aided development process as well as an adequate component library for assembling simulation
Disassembly Process Planning of End-of-Life Car

In order to increase competitiveness and to gain economic benefit, companies ask more and more how to recycle their products in an efficient way. So far, to answer this question, companies are not sufficiently supported by suitable methods specially in the area of disassembly process planning. For this reason, we develop in collaboration with an industrial partner a new method for generating an optimal disassembly sequence. In this paper this method will be described in detail by considering the exiting assembly information, disassembly method and disassembly depth. PLM(Profit-Loss Margin) curve that is used to determine disassembly depth consists of profit value, disassembly cost and disassembly effect. Using assessment parameters, generated alternative disassembly sequences are evaluated and an optimal disassembly sequence is proposed. This method is applied to generate the optimal disassembly sequence of Door Trim as an example.

Overscholing onder Vlaamse schoolverlaters: springplank of valkuil?

Welke strategie dienen werkloze schoolverlaters te volgen met het oog op een snelle transitie naar een job op het niveau van hun kwalificaties? Enkel adequate jobs aannemen om te vermijden vast te raken in niet-adequate jobs? Of jobs waarvoor ze overgeschoold zijn net wel aannemen om zo de transitie naar een adequate job te versnellen? We schatten het causale verband tussen het aanvaarden van een job waarvoor men overgeschoold is en het vinden van een adequate job nadien. Hiervoor baseren we ons op data voor Vlaamse schoolverlaters. Uit onze resultaten blijkt dat overscholing geen springplank, maar een valkuil is.
The Ca2+-gated Cl- channel TMEM16A amplifies capillary pericyte contraction reducing cerebral blood flow after ischemia

Pericyte-mediated capillary constriction decreases cerebral blood flow in stroke after an occluded artery is unblocked. The determinants of pericyte tone are poorly understood. We show that a small rise in cytoplasmic Ca2+ concentration ([Ca2+]i) in pericytes activates chloride efflux through the Ca2+-gated anion channel TMEM16A, thus depolarizing the cell and opening voltage-gated calcium channels. This mechanism strongly amplifies the pericyte [Ca2+]i rise and capillary constriction evoked by contractile agonists and ischemia. In a rodent stroke model, TMEM16A inhibition slows the ischemia-evoked pericyte [Ca2+]i rise, capillary constriction and pericyte death, reduces neutrophil stalling and improves cerebrovascular reperfusion. Genetic analysis implicates altered TMEM16A expression in poor patient recovery from ischemic stroke. Thus, pericyte TMEM16A is a crucial regulator of cerebral capillary function, and a potential therapeutic target for stroke and possibly other disorders of impaired microvascular flow, such as Alzheimer’s disease and vascular dementia.
Strategies to Improve the Barrier and Mechanical Properties of Pectin Films for Food Packaging: Comparing Nanocomposites with Bilayers

Traditional food packaging systems help reduce food wastage, but they also produce environmental impacts when not properly disposed of. Bio-based polymers are a promising solution to overcome these impacts, but they have poor barrier and mechanical properties. This work evaluates two strategies to improve these properties in pectin films: the incorporation of cellulose nanocrystals (CNC) or sodium montmorillonite (MMT) nanoparticles, and an additional layer of chitosan (i.e., a bilayer film). The bionanocomposites and bilayer films were characterized in terms of optical, morphological, hygroscopic, mechanical and barrier properties. The inclusion of the nanofillers in the polymer reduced the water vapor permeability and the hydrophilicity of the films without compromising their visual properties (i.e., their transparency). However, the nanoparticles did not substantially improve the mechanical properties of the bionanocomposites. Regarding the bilayer films, FTIR and contact angle studies revealed no surface and/or chemical modifications, confirming only physical coating/lamination between the two polymers. These bilayer films exhibited a dense homogenous structure, with intermediate optical and hygroscopic properties. An additional layer of chitosan did not improve the mechanical, water vapor and oxygen barrier properties of the pectin films. However, this additional layer made the material more hydrophobic, which may play an important role in the application of pectin as a food packaging material.
A Yap-dependent transcriptional program directs cell migration for embryo axis assembly

The condensation of the embryo primary axis is a fundamental landmark in the establishment of the vertebrate body plan. Although the complex morphogenetic movements directing cell convergence towards the midline have been described extensively, little is known on how gastrulating cells interpret mechanical cues. Yap proteins are among the best characterized transcriptional mechanotransducers, yet their role in gastrulation has remained elusive. Here we show that the double knockout of yap and its paralog yap1b in medaka results in an axis assembly failure. Quantitative live imaging reveals that mutant cells display reduced displacement and migratory persistence. By characterizing the Yap-dependent transcriptional program, we identified genes involved in cytoskeletal organization and cell-ECM adhesion, rather than in germ layer specification, as direct Yap targets. Dynamic analysis of Tead sensors and downstream targets reveals Yap is acting in migratory cells, and not as a midline beacon, to direct gastrulating precursors trajectories by promoting cortical actin recruitment and focal adhesions assembly. We propose that Yap is engaged in a mechano-regulatory loop that is essential to maintain the directed cell migration sustaining embryo axis formation.
