Impacts of ocean warming on echinoderms: A meta-analysis
Authors: Lang Bethan , Donelson Jennifer , Bairos-Novak Kevin , Wheeler Carolyn , Caballes Ciemon , Uthicke Sven , Pratchett Morgan
Published: May 2023

Rising ocean temperatures are threatening marine species and populations
worldwide, and ectothermic taxa are particularly vulnerable to warming.
Echinoderms are an ecologically important phylum of marine ectotherms
and shifts in their population dynamics can have profound impacts on the
marine environment. The effects of warming on echinoderms are highly
variable across controlled laboratory-based studies. Accordingly,
synthesis of these studies will facilitate the better understanding of
broad patterns in responses of echinoderms to ocean warming. Herein, a
meta-analysis incorporating the results of 85 studies (710 individual
responses) is presented, exploring the effects of warming on various
performance predictors. The mean responses of echinoderms to all
magnitudes of warming were compared across multiple biological
responses, ontogenetic life stages, taxonomic classes, and regions,
facilitated by multivariate linear mixed effects models. Further models
were conducted which only incorporated responses to warming greater than
the projected end-of-century mean annual temperatures at the collection
sites. This meta-analysis provides evidence that ocean warming will
generally accelerate metabolic rate (+ 32%) and reduce survival (–
35%) in echinoderms, and echinoderms from sub-tropical (– 9%) and
tropical (– 8%) regions will be the most vulnerable. The relatively
high vulnerability of echinoderm larvae to warming (– 20%) indicates
that this life stage may be a significant developmental bottleneck in
the near-future, likely reducing successful recruitment into
populations. Furthermore, asteroids appear to be the class of
echinoderms that are most negatively affected by elevated temperature
(– 30%). When considering only responses to magnitudes of warming
representative of end-of-century climate change projections, the
negative impacts on asteroids, tropical species and juveniles were
exacerbated (– 51%, – 34%, and – 40% respectively). The results of
these analyses enable better predictions of how keystone and invasive
echinoderm species may perform in a warmer ocean, and the possible
consequences for populations, communities, and ecosystems.
Composition of Soil Frankia Assemblages across Ecological Drivers Parallels that of Nodule Assemblages in Alnus incana ssp. tenuifolia in Interior Alaska
Authors: Anderson Mike , Taylor D , Ruess Roger , Olson Karl
Published: May 2023

In root-nodule symbioses (RNS) between nitrogen (N) fixing bacteria and
plants, bacterial symbionts cycle between nodule-inhabiting and
soil-inhabiting niches that exert differential selection pressures on
bacterial traits. Little is known about how the resulting evolutionary
tension between host plants and symbiotic bacteria structures naturally
occurring bacterial assemblages in soils. We used DNA cloning to examine
soil-dwelling assemblages of the actinorhizal symbiont Frankia in sites
with long-term stable assemblages in Alnus incana ssp. tenuifolia
nodules. We compared: 1) phylogenetic diversity of Frankia in soil vs.
nodules, 2) change in Frankia assemblages in soil vs. nodules in
response to environmental variation: both across succession, and in
response to long-term fertilization with N and phosphorus, and 3) soil
assemblages in the presence and absence of host plants. Phylogenetic
diversity was much greater in soil-dwelling than nodule-dwelling
assemblages, and fell into two large clades not previously observed.
Presence of host plants was associated with enhanced representation of
genotypes specific to A. tenuifolia, and decreased representation of
genotypes specific to a second Alnus species. The relative proportion of
symbiotic sequence groups across a primary chronosequence was similar in
both soil and nodule assemblages. Contrary to expectations, both N and P
enhanced symbiotic genotypes relative to non-symbiotic ones. Our results
provide a rare set of field observations against which predictions from
theoretical and experimental work in the evolutionary ecology of RNS can
be compared.

Published: May 2023

Biomass-derived deep eutectic solvents (DESs) have been introduced as
promising pretreatment and fractionation solvents because of their mild
processing conditions, easy synthesis, and green solvent components from
biomass. In recent DES studies, solvent-based third constituents like
water, ethanol, and others improve the processibility of typical binary
DESs. However, the impacts of these components are not well understood.
Here, two solvent-based constitutions, including water and ethylene
glycol, were applied to 3,4-dihydroxybenzoic acid (DHBA)-based DES
system for improving the conversion efficiency of cellulose-rich
fraction and the properties of lignin fraction. Compositional changes,
enzymatic digestibility of carbohydrate components, and transformation
of lignin were used to evaluate the impact of each constituent on
biomass processing. Ternary DHBA-ChCl DESs exhibited better performances
in delignification, fermentable sugar production, and preservation of
β–O–4 ether linkage in lignin compared to neat ChCl-DHBA DES.

Published: May 2023

A 32-year-old female patient presented with palpitations and chest
discomfort. The patient had a history of pericardiotomy due to
pericardial effusion. Multimodal imaging, including echocardiography,
cardiac magnetic resonance (CMR), and coronary computed tomography
angiography (CCTA) were used showing a pericardial cyst as the cause of
the symptoms. Furthermore its location and potential complications were
accurately defined. The patient underwent successful surgical resection
of the cyst, and histopathological analysis confirmed a bronchogenic
cyst, a very rare congenital malformation. The article discusses the
rarity of bronchogenic cysts in the pericardium and the importance of
accurate diagnosis and appropriate treatment.
The “Double Empathy Problem”: Direct and Indirect Communication Modeled Using Lewis Signaling Games
Authors: Frankle Lana
Published: May 2023

Autism was previously seen as involving impairment in social
communication, theory of mind, and ability to read social cues.
Recently, more neurodiversity-affirming frameworks have been introduced
that characterize barriers to communication and lack of social
understanding between autistics and their neurotypical peers as being a
two-way street: the double-empathy problem. Misunderstandings do not
exist purely due to a deficit in autistic communication, but due to two
different communication styles that are not interpreted by each other as
easily. While this has proved an interesting area of research, attempts
to mechanistically model this are lacking, despite the wealth of game
theory examples that already exist to model cooperation, competition,
and coordination between agents with interdependent strategies. This
paper models real-world examples of social situations using Lewis
signaling games. Within each pairing, pooling by the sender of different
states into the same signals and pooling by the receiver of different
signals into the same action represent the type of indirect
communication, and responsiveness to indirectness, that are often
employed by neurotypical people. In contrast, separating strategies, in
which each state is assigned its own distinct signal and each signal
triggers its own specific response, represent more direct, specific, and
straightforward communication. This work is not meant to make direct
conclusions about autistic-neurotypical or autistic-autistic
communication, as actual human interactions are far too complex to be
governed by the simple strategies outlined in the paper, but rather to
serve as an example of the basic principles that could govern or
influence such interactions.
Statistical modeling of fully nonlinear hydrodynamic loads on offshore wind turbine foundations using wave episodes and targeted CFD simulations through active sampling
Authors: Guth Stephen , Katsidoniotaki Eirini , Sapsis Themistoklis
Published: May 2023

For many design applications in offshore engineering, including offshore
wind turbine foundations, engineers need accurate statistics for
kinematic and dynamic quantities, such as hydrodynamic forces, whose
statistics depend on the stochastic sea surface elevation. Nonlinear
phenomena in the wave–structure interaction require high-fidelity
simulations to be analyzed accurately. However, accurate quantification
of statistics requires a massive number of simulations, and the
computational cost is prohibitively expensive. To avoid that cost, this
study presents a machine learning framework to develop a reliable
surrogate model that minimizes the need for computationally expensive
numerical simulations, which is implemented for the monopile foundation
of an offshore wind turbine. This framework consists of two parts. The
first focuses on dimensionality reduction of stochastic irregular wave
episodes and the resulting hydrodynamic force time series. The second of
the framework focuses on the development of a Gaussian process
regression surrogate model which learns a mapping between the wave
episode and the force-on-structure. This surrogate uses a Bayesian
active learning method that sequentially samples the wave episodes
likely to contribute to the accurate prediction of extreme hydrodynamic
forces in order to design subsequent CFD numerical simulations.
Additionally, the study implements a spectrum transfer technique to
combine CFD results from quiescent and extreme waves. The principal
advantage of this framework is that the trained surrogate model is
orders of magnitude faster to evaluate than the classical modeling
methods, while built-in uncertainty quantification capabilities allows
for efficient sampling of the parameter using with the CFD tools
traditionally employed.
Water Resources in the Truckee Meadows
Authors: Steeland Kara , Hauck Bill , Pohll Greg , Enloe John , Morris Stefanie
Published: May 2023

Over the last century water supply and demand conditions have changed in northern Nevada. Climate change is causing increased temperatures, evaporation, and declining snowpack storage (Siirila-Woodburn, 2021). There is considerable uncertainty about the future magnitude of annual precipitation (Lynn, et al., 2015), but increased variability is expected (Zhang et al., 2021; Gonzalez et al., 2018). Increased precipitation variability may translate into longer and more severe droughts or more frequent flooding. Continued warming trends will likely result in more precipitation falling as rain instead of snow, which has the potential to decrease the region’s snowpack (Harpold et al., 2017; Hatchett et al., 2018; Cooper et al., 2016). Changing conditions will require changes in water resources management strategies to improve efficiencies, and sustained actions that conserve available resources and ongoing adaptive management. The Truckee Meadows Water Authority (TMWA) manages its water resources to provide a resilient and reliable water supply for the region. TMWA is continuing its adaptive management strategy by analyzing a broad range of future conditions and planning for solutions to deal with the changing climate and increasing population. This article provides an overview of TMWA, its service area, supply sources, water rights, future supply scenarios, and adaptive management strategies (TMWA, 2020).

Authors: Obradovic Nina , Filipovic Suzana , Fahrenholtz William , Marinkovic Bojan , Rogan Jelena , Levic Steva , Djordjevic Antonije , Pavlovic Vladimir
Published: May 2023

Magnesium aluminate has the spinel structure along with good mechanical,
chemical, and thermal properties. Magnesium aluminate has a wide range of
applications including refractory ceramics, optically transparent ceramic
windows, and armors. Its low dielectric permeability and low loss tangent
enable its applications for integrated electronic devices, as well. In this
paper, MgO and Al2O3 powders were mixed in a one-to-one molar ratio and
calcined at temperatures ranging from 1500 to 1800oC to produce phase pure
spinel. Thereafter, pellets were crushed and treated in a planetary ball
mill for 60 min to obtain a fine powder. All powders were examined for phase
composition, crystal structure, and morphology. The obtained results showed
that by increasing the temperature, samples with higher density were
synthesized. Milling for 1 h led to formation of larger particles, but finer
powders after milling. XRPD and Raman spectroscopy showed disorder in the
crystal structure after milling.
The effect of sintering temperature and time on microstructure, hardness and wear behaviors of Al 99.9/GNP composites
Authors: Pul Muharrem , Erdem Umit , Pehlivanli Onur
Published: May 2023

In this study, it was aimed to investigate the microstructure, hardness and
wear behavior of graphene nanoplate (GNP) reinforced composites with Al 99.9
matrix produced by powder metallurgy. Different temperatures and times were
applied in the sintering process. The hardness values of the composites
increased as the sintering temperature and time increased. The hardness
values decreased with the increase of GNP reinforcement ratio. The wear
losses decreased depending on the increase in sintering temperature and
time. With the increase in the GNP reinforcement ratio, reductions in wear
losses were recorded. It has been concluded that the GNP reinforcement
element in the composite structure reduces the friction coefficient and wear
losses by having some lubricating effect. It was observed that the neck and
bonding formation between Al 99.9 matrix grains improved with increasing
sintering temperature and time. It was concluded that with the development
of intergranular bonds, the porosity in the composite structure decreased
and the mechanical properties increased.
Importance of practical measures and agroecological conditions for formation of yield and quality of sugar beet in Vojvodina
Authors: Marinkovic Branko , Crnobarac Jovan
Published: May 2023

Yields of cultivated plants are the result of congruence between cultivated plant demands and agro ecological conditions of the region. Fertilization is a practical measure associated with the highest losses. In actual production conditions, deficiency in NPK nutrition results in losses up to 2.1-14.9 t ha?1, excess amounts of these nutrients in losses of 5.8-18.9 t ha?1. Quality losses are important, too. Decreases in sugar content fluctuate between 0,2% and 0,9%, sugar utilization from 0,3-7,6% and total sugar losses from 380 to 1060 kgha?1.

Expected return, stock valuation, and the capital structure: comparing the Gordon model and the capital asset pricing model
Authors:   LeTourneau University, Texas, USA, Smith J. Mark
Published: May 2023

Expected returns, stock valuation methods, and capital structure management have a major influence on the effectiveness of the company’s financial strategy. This study analyzes a sample portfolio to consider how the expected rate of return is assigned, how common stock is valued, and how equity and debt are targeted in the firm’s capital structure. The validity of an algorithm that values common stock depends on accurate assessment of the expected return. Company policy for acquiring capital and paying dividends could alter the expected return. The capital asset pricing model (CAPM) helps judge the role of certain factors in determining expected return and stock value. In the sample portfolio, we shall work with one valuation method, the Gordon Model of constant growth, and compare its expected returns with the CAPM. The CAPM considers the risk-free rate, the market risk premium, and a systematic risk index, while the Gordon Model assigns value of stocks based on dividend growth. We examine dividend payout policy to find that it influences differences between the Gordon Model and the CAPM’s expected returns. Both methods help determine how the cost of equity may be applied to the firm’s capital structure, usually in the weighted average cost of capital (WACC). Tax factors in the WACC influence the proportions of debt and equity in the capital structure. The tax benefit of debt makes debt the least expensive source of capital funding, but its use should be limited due to the higher risk of debt. Manipulations within the WACC have an influence on the mix of funding sources in the capital structure, the cost of both debt and equity, and the stock price. Therefore, the discussion will further consider the topic of capital structure optimization. This previously unpublished paper is the original work of the author.
