Projections of Extreme Ocean Waves in the Arctic and Potential Implications for Coastal Inundation and Erosion

The Arctic Ocean wave climate is undergoing a dramatic change due to the sea ice retreat. This study presents simulations of the Arctic regional wave climate corresponding to the surface winds and sea ice concentrations as simulated by ﬁ ve CMIP5 (Coupled Model Intercomparison Project Phase 5) climate models for the historical (1975 – 2005) and RCP8.5 scenario future (2081 – 2100) periods. The annual maximum signi ﬁ cant wave height is projected to increase up to 6 m offshore and up to two to three times greater than the corresponding 1979 – 2005 value along some coastlines, as waves become more exposed to the fall storms there. The connection between the Atlantic Ocean and the Arctic wave climates is projected to strengthen due to increase of swell in ﬂ uence. Changes in the wave direction also seem to indicate a weakening of the Beaufort High illustrated by a counterclockwise rotation of the mean wave direction for extreme conditions in the Western Arctic. The projected changes in wave conditions lead to a general increase of the wave ‐ driven erosion and inundation potential along the Arctic coastlines. Potentially, hazardous extreme wave events are projected to become signi ﬁ cantly more frequent and more intense. For example, in the Beaufort coastlines a once ‐ in ‐ 20 ‐ year event under the historical (1979 – 2005) climate is projected to occur, on average, once every 2 – 5 years during 2081 – 2100. This is a pressing issue, as it affects many Arctic coastal communities, as well as existing and emerging Arctic infrastructure and activities, with some of them having already suffered severe wave ‐ induced damage in the past years. Key Points: • This study presents the ﬁ rst multimodel ensemble of projected extreme wave climate in the Arctic region • The annual maximum of the signi ﬁ cant wave height is projected toincrease upto6moffshoreandup to two to three times along the coastlines • The more energetic future waves are likely to pose a hazard to the Arctic communities and infrastructure due to ﬂ ooding and erosion
Using Ensembles for Accurate Modelling of Manufacturing Processes in an IoT Data-Acquisition Solution

The development of complex real-time platforms for the Internet of Things (IoT) opens up a promising future for the diagnosis and the optimization of machining processes. Many issues have still to be solved before IoT platforms can be profitable for small workshops with very flexible workloads and workflows. The main obstacles refer to sensor implementation, IoT architecture, and data processing, and analysis. In this research, the use of different machine-learning techniques is proposed, for the extraction of different information from an IoT platform connected to a machining center, working under real industrial conditions in a workshop. The aim is to evaluate which algorithmic technique might be the best to build accurate prediction models for one of the main demands of workshops: the optimization of machining processes. This evaluation, completed under real industrial conditions, includes very limited information on the machining workload of the machining center and unbalanced datasets. The strategy is validated for the classification of the state of a machining center, its working mode, and the prediction of the thermal evolution of the main machine-tool motors: the axis motors and the milling head motor. The results show the superiority of the ensembles for both classification problems under analysis and all four regression problems. In particular, Rotation Forest-based ensembles turned out to have the best performance in the experiments for all the metrics under study. The models are accurate enough to provide useful conclusions applicable to current industrial practice, such as improvements in machine programming to avoid cutting conditions that might greatly reduce tool lifetime and damage machine components.
The Effects of Loaded Plyometric Exercise during Warm-Up on Subsequent Sprint Performance in Collegiate Track Athletes: A Randomized Trial

Prior evidence demonstrates the efficacy by which plyometric activities during warm-up conditions augment the subsequent performance in power-centric exercise. We investigated the acute effects of loaded jump squats incorporated into a standard sprinters’ warm-up protocol on subsequent sprint performance in collegiate track athletes. Sprint times of 22 male and female collegiate track athletes were measured in 10-m intervals during a 30-m sprint trial following a standard sprinters’ warm-up routine with or without plyometric exercise. Subjects were tested on two separate occasions, once with loaded jump squats as the experimental treatment (two sets of eight jumps, load = 13% bodyweight) (PLYO) and once with time-equated rest as the control treatment (CON). Treatments were implemented following a standard sprinters’ warm-up routine familiar to the subjects. A dependent T-test was used for comparison of sprint interval times between conditions with a significant effect indicated by a p-value < 0.05. Sprint time did not differ between CON vs. PLYO at the 10 m (PLYO = 1.90 ± 0.12 s vs. CON = 1.90 ± 0.11 s, p = 0.66), 20 m (PLYO = 3.16 ± 0.21 s vs. CON = 3.15 ± 0.19 s, p = 0.53), and 30 m (PLYO = 4.32 ± 0.32 s vs. CON = 4.31 ± 0.28 s, p = 0.61) intervals. There was no interaction between treatment and sex, sex-specific ranking (above vs. below sex-specific mean), or sprint event (short vs. short–long vs. long) for 10 m, 20 m, or 30-m interval sprint times. At least within the limits of the current investigation, no evidence was provided to suggest that jump squats loaded at 13% bodyweight are an effective means to acutely potentiate sprint performance in collegiate track athletes. However, a further examination of responders indicates that the present loaded jump squat protocol may preferentially potentiate sprint performance in faster male athletes.
Detection of Periodicity in SiO Maser Intensity and Velocity Shift of the Symbiotic Star CH Cyg

We performed simultaneous monitoring observations of H2O 616–523 and SiO v = 1, 2, 0, SiO v = 1, 1, maser lines toward the symbiotic star CH Cyg from 2012 December to 2019 November using the Korean very long baseline interferometry Network single-dish telescope. SiO v = 1, 2, and v = 1, maser lines were detected for the first time. A periodicity of about 2.5 yr in the SiO maser intensity was found, showing its association with the pulsation of the M giant in CH Cyg. Only the SiO v = 2, maser, without detections of the v = 1, maser, was detected in 6 epochs out of 15 v = 2, J = 1–0 maser detected epochs. In addition, the SiO v = 1, maser intensity was always stronger than that of the v = 1, maser except for one epoch, providing a critical constraint on the different masing conditions by different transitions, according to changes of the CH Cyg symbiotic system. We also found the gradual redshifted peak velocities of the SiO masers had about a 2.5 yr periodicity corresponding to the period of peak intensities (redshifted up to about with respect to the stellar velocity of the M giant). Two possible explanations can be suggested for the 2.5 yr period of the SiO maser intensity and velocity behaviors, although their actual causes remain uncertain.
βVPE is involved in tapetal degradation and pollen development by activating proprotease maturation in Arabidopsis thaliana

Vacuolar processing enzyme (VPE) is responsible for the maturation and activation of vacuolar proteins in plants. We found that βVPE was involved in tapetal degradation and pollen development by transforming proproteases into mature protease in Arabidopsis thaliana. βVPE was expressed specifically in the tapetum from stages 5-8 of anther development. The βVPE protein first appeared as a proenzyme and transformed into the mature enzyme before stages 7-8. The recombinant βVPE protein self-cleaved and transformed to a 27-kD mature protein at pH 5.2. The mature βVPE protein could induce the maturation of CEP1 in vitro. βvpe mutants exhibited delayed vacuolar degradation and decreased pollen fertility. The maturation of CEP1, RD19A, and RD19C were seriously inhibited in βvpe mutants. Our results indicate that βVPE is a crucial processing enzyme that directly participates in the maturation of cysteine proteases before vacuolar degradation, and is indirectly involved in pollen development and tapetal cell degradation. Highlight βVPE is a crucial processing enzyme that directly participates in the maturation of cysteine proteases before vacuolar degradation, and is indirectly involved in pollen development and tapetal cell degradation.
Technological Developments and Transitions in Israel’s Preschool Television Industry

This article documents two ethnographic explorations (2012, 2015) held at Hop! group based in Israel, when it was in transition from being a preschool television company into a preschool content group. Three core challenges presented by new technologies were revealed: the need to be present on every screen; understanding the affordances of each technology; and finding successful collaborations. The article discusses the ways in which Hop! addressed those challenges, focusing on the transition from a dedicated television set into a multiplicity of screens; the negotiation of the new platforms’ affordances; and the development of a workforce suitable for platform content production. These challenges reveal that despite the feeling of revolution within the company caused by the great extent and rapid pace of technological innovation, what we see is a potentially endless transition period since, like the mythological hydra, after the affordances of new technologies become clear another technology springs up.
Whose Genes Are They?: The Human Genome Diversity Project

Summary The Human Genome Diversity Project (HGDP) has targeted several hundred indigenous peoples worldwide as their source of genetic material. Proponents for this project claim that information derived by analyzing these materials may be used for a variety of purposes ranging from finding a cure for diabetes to resolving debates about human origins. However, the HGDP plan raises many issues for indigenous people. This paper describes the project as well as the possible ethical and policy implications for Native communities.
Aggregated Conducted Electromagnetic Interference Generated by DC/DC Converters with Deterministic and Random Modulation

The assessment of electromagnetic compatibility (EMC) is important for both technical and legal reasons. This manuscript addresses specific issues that should be taken into account for proper EMC assessment of energy systems that use power electronic interfaces. The standardized EMC measuring techniques have been used in a laboratory setup consisting in two identical DC/DC converters with deterministic and random modulations. Measuring difficulties caused by the low frequency envelopes, resulting from frequency beating accompanying aggregation of harmonic components of similar frequencies, were indicated as a phenomenon that might lead to significant problems during the EMC assessment using currently binding standards. The experimental results describing deterministic and random modulated converters might be useful for practitioners implementing power interfaces in microgrids and power systems as well as for researchers involved in EMC assurance of power systems consisting in multiple power electronic interfaces.
From Intention to Trust to Behavioral Trust: Trust Building in Family Business Advising

By building on foundations from psychology, we aim to enhance academic understanding of the advising process in family businesses. We find evidence, based on rich qualitative data, suggesting that trust serves as a key construct in the relationship between family businesses and their advisors. In particular, we empirically show and theorize that trusting relationships evolve via a nonlinear process characterized by a constant interplay between cognitive and—increasingly important—affective assessments of family business trustors. The following types of trust emerge from these internal assessments: an intention to trust, which develops into perceived trust and finally results in behavioral trust.
Spatial Diversity and Multiplexing Effects on Uplink Multi-hop LTE-Advanced (Dept. E)

Multi-hop Relay networks are proposed to fulfill the demanding coverage and capacity requirements in both uplink and downlink for current applications in a cost efficient way. It can be used in IMT-Advanced technologies such as 3GPP LTE-Advanced. Spatial Diversity (SD) and Multiplexing (SM) have been adopted to improve the Signal to interference Noise Ratio (SINR) and spectrum efficiency in wireless networks. The objective of this paper is to evaluate the performance of Spatial Diversity and Multiplexing based on Adaptive modulation and coding (AMC) schemes in Uplink LTE-A. The average throughput, Throughput gain, and Mean File Transfer Time (MFTT) are considered as performance measures. The best Relay Station (RS) location in the cell was also estimated in order to improve LTE-A Uplink performance. The study takes into consideration the impact of Asymmetry between multi-hop links, the effect of different arrival rates from random positions of UEs in the cell. Resource blocks scheduling algorithm is used for more efficient use of resource blocks (RBs). Simulation results show effective improvement in uplink network performance by Combining Spatial Diversity and Multiplexing in 2x4MIMO system with RS at 50% of cell radius towards cell edge.
Macroevolution of dimensionless life history metrics in tetrapods

Life history traits represent organism’s strategies to navigate the fitness trade-offs between survival and reproduction. Eric Charnov developed three dimensionless metrics to quantify fundamental life history trade-offs. Lifetime reproductive effort (LRE), relative reproductive lifespan (RRL), and relative offspring size (ROS), together with body mass, can be used classify life history strategies across the four major classes of tetrapods: amphibians, reptiles, mammals, and birds. First, we investigate how the metrics have evolved in concert with body mass. In most cases, we find evidence for correlated evolution between body mass and the three metrics. Finally, we compare life history strategies across the four classes of tetrapods and find that LRE, RRL, and ROS delineate a space in which the major tetrapod clades occupy mostly unique subspaces. These distinct combinations of life history strategies provide us with a framework to understand the impact of major evolutionary transitions in energetics, physiology, and ecology.
Cell Wall and Whole Cell Proteomes Define Flocculation and Fermentation Behavior of Yeast

Flocculation is one of the most important characteristics of brewing yeast as it allows for the easy and cheap removal of cells after fermentation. The genes responsible for both the Flo1 and NewFlo flocculation phenotypes are well characterized. However, the relationship between Flo protein abundance and flocculation efficiency is poorly understood. In this present study, we used mass spectrometry proteomics to compare the cell wall and whole cell proteomes of commercial yeast strains with diverse flocculation behaviors. We found that the relative abundance of Flo1/5 or Flo10 in the cell wall was correlated with the ability of these yeast strains to flocculate. Analysis of whole cell proteomes identified differences in the proteomes of yeast strains and identified the potential for high metabolic diversity. Characterization of the cell wall and whole cell proteomes during fermentation showed high levels of Flo10 in cells that settled early during fermentation. Our data reveal the diversity of the cell wall and global proteomes of brewing yeast, highlighting the potential biochemical diversity present in yeast that can be utilized in the production of fermented beverages.
Improving polyhydroxyalkanoate production from inexpensive carbon sources by genetic approaches: a review

Polyhydroxyalkanoates (PHAs) are a family of biodegradable intracellular polyesters that a number of Eubacteria and Archaea can accumulate for energy and carbon storage. Most of the genetic modifications to the producing bacterial species have been accomplished to clarify basic biochemical, genetic, and metabolic aspects of PHA metabolism. However, due to its plastic‐like properties and complete biodegradability, this bio‐based polymer has attracted the attention of a variety of manufacturers. A number of genetic approaches have therefore been reported, aimed at improving the performance of the microorganisms with a potential for use in a production process. Indeed, genetic tools may find useful applications in all the phases of the PHA production chain, from the isolation and characterization of new microbial strains through all the production steps until they reach the downstream processes. The substrates generally used for PHA production are expensive, so the search for low‐cost feedstock is necessary. These materials, possibly deriving from agri‐food processes, are unfortunately not easily degraded or converted directly into PHAs. Thus, the development of engineered microbes is in progress to process waste streams and covert them to valuable polymers. This review will summarize the most relevant results obtained through genetic engineering tools for the production of PHAs from cheap carbon sources in view of possible industrial applications. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.
Cognitive flexibility in humans and other laboratory animals

ABSTRACT Cognitive flexibility refers to the mental processes that allow us to adapt our behaviour as environmental circumstances change. In this paper, we describe various procedures that are commonly used to measure cognitive flexibility in humans. We then provide evidence of a relationship between cognitive inflexibility and various psychiatric disorders. In laboratory animals, behavioural flexibility is often measured using procedures that are analogous to those used in humans to measure cognitive flexibility. These procedures are described and the merits and limitations of each are presented. Finally, a brief description of how these various procedures can be used to understand the neurobiology of cognitive flexibility is provided.
LA CRISE COVID-19 AMORCE-T-ELLE UNE NOUVELLE TENTATIVE DE REFORMES ECONOMIQUES EN ALGERIE?

La crise sanitaire Covid-19 a ebranle le monde. En plus de son lot de deces et pression sur le secteur et les praticiens de la sante, d’autres effets sont a craindre, specialement, sur le plan economique. Cette crise, a coincide, pour l’Algerie, avec une crise petroliere tres aigue qui persiste depuis 2014. Cette situation devenue intenable, a pousse le gouvernement a redurie les depenses publiques de fonctionnement de 50%. 1Cette crise devrait etre une opportunite pour en finir une fois pour toute avec le spectre de la rente. Longtemps consideree comme une aubaine et don du ciel, cette rente a fini par devenir une malediction. Les effets de Covid-19 devraient accelerer le processus de reformes releguees a chaque fois pour des considerations aussi bien politiques que d’ordre economiques. La pandemie a revele des secteurs qui ont bien reagi a cette crise. D’autres secteurs ont montre un potentiel reel qui doit etre valorise (recherche scientifique, par exemple). Des secteurs restent a la traine et souffrent d’un desequilibre chronique et la Covid-19 n’a fait qu’aggraver leur situation. Mots Cles : Covid-19, reformes economiques, systeme de sante, crise economique, politique economique English Title: Is the covid-19 crisis starting a new attempt of economic reform in Algeria? The Covid-19 health crisis has shaken the world. In addition to the death rate it has caused and the pressure on the health sector and its practitioners, other effects are to be feared, especially, on the economic level. This crisis coincided, for Algeria, with a very acute oil crisis which has persisted since 2014. This situation became untenable, pushed the government to cut public operating expenditure by 50%. This crisis should be an opportunity to end the rent spectrum once and for all. Long considered a boon and a gift from heaven, this rent ended up becoming a curse. The effects of Covid-19 are expected to accelerate the process of reforms, relegated each time for political rather than economic considerations. The pandemic has shown areas that have responded well to this crisis. Other sectors have shown enormous potential that has been ignored or forgotten and needs to be harnessed (scientific research, for example). Sectors lag behind and suffer from a chronic imbalance and the Covid-19 has only worsened their situation. Key words: Covid-19, economic reforms, health system, economic crisis, economic policy
Turing Instability and Pattern Formation in a Strongly Coupled Diffusive Predator-Prey System

We are concerned with the Turing instability and pattern caused by cross-diffusion in a strongly coupled spatial predator–prey system. We explore how cross-diffusion destabilizes the spatially uniform steady state which is stable in reaction–diffusion systems, and explicitly describe the Turing space under certain conditions. Particularly, when the parameter values are taken in the Turing–Hopf domain, in which the spatiotemporal dynamical behavior is influenced by both Hopf and Turing instabilities, we investigate the formation of all possible patterns, including non-Turing structures such as wave pattern, competing dynamics as well as stationary Turing pattern. Furthermore, numerical simulations are illustrated to verify our theoretical findings.
Interest-Free Financing Promotions Increase Consumers’ Demand for Credit for Experiential Goods

This research provides a first investigation into how interest-free financing promotions influence consumer behavior. Five experiments demonstrate that framing an economically equivalent financing offer in a way that makes salient that it is interest-free increases consumers’ demand for credit to finance experiential, but not material goods. This increased willingness to finance manifests for primarily experiential goods (e.g., vacations), goods with mixed benefits (e.g., bike) if their experiential aspects are highlighted, and mixed shopping baskets that provide primarily experiential benefits. Using mediation and moderation, the results suggest that this occurs because interest-free cues mitigate feelings of debt aversion for experiential purchases. Based on our findings, we highlight public policy and managerial implications.
