Published: May 2020

Sulfur has been considered to be a predominant light element in the Martian core, and thus the sound velocity of Fe-S alloys at relevant high pressure and temperature is of great importance to interpret its seismological data. Here we measured the compressional sound velocity (VP) of liquid Fe, Fe80S20 and Fe57S43 using ultrasonic pulse-echo overlap method combined with a Kawai-type multi-anvil apparatus up to 20 GPa, likely corresponding to the condition at the uppermost core of Mars. The results demonstrate that the VP of liquid iron is least sensitive to its sulfur concentration in the Mars’ whole core pressure range. The comparison of seismic wave speeds of Fe-S liquids with future observations will therefore tell whether the Martian core is molten and contains impurity elements other than sulfur.

Combining MoS2 monolayers to form multilayers allows to access new functionalities. Deterministic assembly of large area van der Waals structures requires concrete indicators of successful interlayer coupling in bilayers grown by chemical vapor deposition. In this work, we examine the correlation between the stacking order and the interlayer coupling of valence states in both as-grown MoS2 homobilayer samples and in artificially stacked bilayers from monolayers, all grown by chemical vapor deposition. We show that hole delocalization over the bilayer is only allowed in 2H stacking and results in strong interlayer exciton absorption and also in a larger A-B exciton separation as compared to 3R bilayers. Comparing 2H and 3R reflectivity spectra allows to extract an interlayer coupling energy of about t⊥ = 49 meV. Beyond DFT calculations including excitonic effects confirm signatures of efficient interlayer coupling for 2H stacking in agreement with our experiments.

Mammalian hearing requires the development of the organ of Corti, a sensory epithelium comprising unique cell types. The limited number of each of these cell types, combined with their close proximity, has prevented characterization of individual cell types and/or their developmental progression. To examine cochlear development more closely, we transcriptionally profile approximately 30,000 isolated mouse cochlear cells collected at four developmental time points. Here we report on the analysis of those cells including the identification of both known and unknown cell types. Trajectory analysis for OHCs indicates four phases of gene expression while fate mapping of progenitor cells suggests that OHCs and their surrounding supporting cells arise from a distinct (lateral) progenitor pool. Tgfβr1 is identified as being expressed in lateral progenitor cells and a Tgfβr1 antagonist inhibits OHC development. These results provide insights regarding cochlear development and demonstrate the potential value and application of this data set.

Published: May 2020

The possibility of Bell inequality violations in quantum theory had a profound impact on our understanding of the correlations that can be shared by distant parties. Generalizing the concept of Bell nonlocality to networks leads to novel forms of correlations, the characterization of which is, however, challenging. Here, we investigate constraints on correlations in networks under the natural assumptions of no-signaling and independence of the sources. We consider the triangle network with binary outputs, and derive strong constraints on correlations even though the parties receive no input, i.e., each party performs a fixed measurement. We show that some of these constraints are tight, by constructing explicit local models (i.e. where sources distribute classical variables) that can saturate them. However, we also observe that other constraints can apparently not be saturated by local models, which opens the possibility of having nonlocal (but non-signaling) correlations in the triangle network with binary outputs.

Published: May 2020

Although low vegetation productivity has been observed in karst regions, whether and how bedrock geochemistry contributes to the low karstic vegetation productivity remain unclear. In this study, we address this knowledge gap by exploring the importance of bedrock geochemistry on vegetation productivity based on a critical zone investigation across a typical karst region in Southwest China. We show silicon and calcium concentrations in bedrock are strongly correlated with the regolith water loss rate (RWLR), while RWLR can predict vegetation productivity more effectively than previous models. Furthermore, the analysis based on 12 selected karst regions worldwide further suggest that lithological regulation has the potential to obscure and distort the influence of climate change. Our study implies that bedrock geochemistry could exert effects on vegetation growth in karst regions and highlights that the critical role of bedrock geochemistry for the karst region should not be ignored in the earth system model.

Published: May 2020

Soil micro-organisms drive the global carbon and nutrient cycles that underlie essential ecosystem functions. Yet, we are only beginning to grasp the drivers of terrestrial microbial diversity and biogeography, which presents a substantial barrier to understanding community dynamics and ecosystem functioning. This is especially true for soil protists, which despite their functional significance have received comparatively less interest than their bacterial counterparts. Here, we investigate the diversification of Pinnularia borealis, a rare biosphere soil diatom species complex, using a global sampling of >800 strains. We document unprecedented high levels of species-diversity, reflecting a global radiation since the Eocene/Oligocene global cooling. Our analyses suggest diversification was largely driven by colonization of novel geographic areas and subsequent evolution in isolation. These results illuminate our understanding of how protist diversity, biogeographical patterns, and members of the rare biosphere are generated, and suggest allopatric speciation to be a powerful mechanism for diversification of micro-organisms.

Authors: Sawada Ryohto , Iwasaki Yuma , Ishida Masahiko
Published: May 2020

We present semi-supervised information maximizing self-argument training (IMSAT), a neural network-based classification method that works without the preparation of labeled data. Semi-supervised IMSAT can amplify specific differences and avoid undesirable misclassification in accordance with the purpose. We demonstrate that semi-supervised IMSAT has a comparable performance with existing methods for semi-supervised learning of image classification and can also classify real experimental data (X-ray diffraction patterns and thermoelectric hysteresis curves) in the same way even though their shape and dimensions are different. Our algorithm will contribute to the automation of big data processing and artificial intelligence-driven material development.
Secure multiparty quantum computation based on Lagrange unitary operator
Authors: Song Xiuli , Gou Rui , Wen Aijun
Published: May 2020

As an important subtopic of classical cryptography, secure multiparty quantum computation allows multiple parties to jointly compute their private inputs without revealing them. Most existing secure multiparty computation protocols have the shortcomings of low computational efficiency and high resource consumption. To remedy these shortcomings, we propose a secure multiparty quantum computation protocol by using the Lagrange unitary operator and the Shamir (t, n) threshold secret sharing, in which the server generates all secret shares and distributes each secret share to the corresponding participant, in addition, he prepares a particle and sends it to the first participant. The first participant performs the Lagrange unitary operation on the received particle, and then sends the transformed particle to the next participant. Until the last participant’s computation task is completed, the transformed particle is sent back to the server. The server performs Lagrange unitary operation on the received particle by using a secret message, and then measures the transformed particle to obtain the sum of the calculations of multiple participants. Security analysis shows that the proposed protocol can resist intercept-measurement attack, intercept-resend attack, entanglement-swapping attack, entanglement-measurement attack and collusion attack. Performance comparison shows that it has higher computation efficiency and lower resource consumption than other similar protocols.

Published: May 2020

Neuronal cell types are essential to the comprehensive understanding of the neuronal function and neuron can be categorized by their anatomical property. However, complete morphology data for neurons with a whole brain projection, for example the pyramidal neurons in the cortex, are sparse because it is difficult to trace the neuronal fibers across the whole brain and acquire the neuron morphology at the single axon resolution. Thus the cell types of pyramidal neurons have yet to be studied at the single axon resolution thoroughly. In this work, we acquire images for a Thy1 H-line mouse brain using a fluorescence micro-optical sectioning tomography system. Then we sample 42 pyramidal neurons whose somata are in the layer 5 of the motor cortex and reconstruct their morphology across the whole brain. Based on the reconstructed neuronal anatomy, we analyze the axonal and dendritic fibers of the neurons in addition to the soma spatial distributions, and identify two axonal projection pattern of pyramidal tract neurons and two dendritic spreading patterns of intratelencephalic neurons. The raw image data are available upon request as an additional asset to the community. The morphological patterns identified in this work can be a typical representation of neuron subtypes and reveal the possible input-output function of a single pyramidal neuron.
Therapeutic apheresis within immune-mediated neurological disorders: dosing and its effectiveness

Published: May 2020

Plasma exchange (PE) and immunoadsorption (IA) are standard therapeutic options of immune-mediated neurological disorders. This study evaluates the relation of the relative quantity of applied dose of PE and/ or IA and its achieved therapeutic effectiveness within the treated underlying neurological disorders. In a retrospective study, we evaluated data from PE and IA carried out 09/2009-06/2014 in neurological patients at the University-Hospital of Saarland, Germany. Apheresis dose was defined as the ratio of the extracorporeal treated plasma volume to the patient’s plasma volume. Effectiveness was assessed through disease-specific tests and scores by the attending neurologist(s); results were classified into response or no response. 1101 apheresis (PE:238, IA:863), in 153 hospital-stays were carried out, averaged, 7.0 treatments per patients, 82% responded, 18% not. Mean applied apheresis dose per treatment was 0.91 with mean doses of 1.16 for PE and 0.81 for IA. The totally applied mean dose per stay was 5.6 (PE:5.01, IA:5.81). No correlation was seen between apheresis dosing and treatment effectiveness (PE:R2 = 0.074, IA:R2 = 0.0023). PE and IA in therapy-refractory immune-mediated neurological disorders majorly achieved a measurable severity improvement – without correlation to the applied dose. Moreover, our data rather suggest, that effectiveness may be given with volumes below currently recommended volumes.
The Effects of Extreme Weather on Apple Quality
Authors: Dalhaus Tobias , Schlenker Wolfram , Blanke Michael M. , Bravin Esther , Finger Robert
Published: May 2020

A large literature has documented the effects of weather on agricultural yields. However, weather not only impacts the quantity produced, but also the quality of the product. Due to data limitations, the quality effects have primarily been studied using lab experiments for specific attributes, and the financial implications for farmers of a quality effect are less clear. Using a unique longitudinal micro-level data set of Swiss apple orchards that include information on both the quantity produced as well as the quality, we show that the latter can have an even larger effect on farm revenue. Ignoring the quality of the harvested product substantially biases the impact of weather extremes on agricultural income and the potential effects of climate change. Our quality measure is the orchard-year specific price shock. If an orchard gets a lower price for its specific apple variety compared to previous years and compared to other orchards in the same year, we observe the market’s valuation of its inferior quality accounting for overall price movements (other orchards growing same variety that year) as well as orchard specific factors (orchard fixed effects). We find that spring frost events induce farm gate price drops and thus revenue reductions of up to 2.05% per hour of exposure.

Published: May 2020

This study aimed to investigate whether interdental brush shape influences cleaning efficacy, by comparing a waist-shaped interdental brush (W-IDB) with a cylindrical IDB (C-IDB); both provided with the same bristle texture. Cleaning efficacy of differently shaped IDBs was measured in proximal surfaces of teeth in a split-mouth cross-over design. Twenty-eight patients abolished oral hygiene for 4 d. Line angle plaque area was scanned with an intraoral camera after use of disclosing dye in baseline and after IDB application and analyzed planimetrically. Additionally, bacterial load in the IDBs was analyzed after usage by colony forming units (cfu). A Wilcoxon signed-rank test with continuity correction was used to compare the results of the waist-shaped and the cylindrically-shaped IDBs. The waist-shaped IDBs cleaned significantly better than their cylindrically-shaped counterparts (area cleaned: 23.1% vs. 18.3%), when applied at same interdental spaces (p < 0.001). However, no significant differences were found in comparison of bacterial load on the IDBs (median cfu counts: 2.3E9 vs. 2.7E9, p = 0.93). Irrespective of bristle texture or size, IDB shape have impact on cleaning efficacy. Waist-shaped IDBs are more effective in cleaning of the line angle area than cylindrically-shaped IDBs.

Published: May 2020

We acquired depth-resolved light scattering measurements from the retinas of triple transgenic Alzheimer’s Disease (3xTg-AD) mice and wild type (WT) age-matched controls using co-registered angle-resolved low-coherence interferometry (a/LCI) and optical coherence tomography (OCT). Angle-resolved light scattering measurements were acquired from the nerve fiber layer, outer plexiform layer, and retinal pigmented epithelium using image guidance and segmented thicknesses provided by co-registered OCT B-scans. Analysis of the OCT images showed a statistically significant thinning of the nerve fiber layer in AD mouse retinas compared to WT controls. The a/LCI scattering measurements provided complementary information that distinguishes AD mice by quantitatively characterizing tissue heterogeneity. The AD mouse retinas demonstrated higher mean and variance in nerve fiber layer light scattering intensity compared to WT controls. Further, the difference in tissue heterogeneity was observed through short-range spatial correlations that show greater slopes at all layers of interest for AD mouse retinas compared to WT controls. A greater slope indicates a faster loss of spatial correlation, suggesting a loss of tissue self-similarity characteristic of heterogeneity consistent with AD pathology. Use of this combined modality introduces unique tissue texture characterization to complement development of future AD biomarker analysis.
Correlation-centred variable selection of a gene expression signature to predict breast cancer metastasis
Authors: Hikichi Shiori , Sugimoto Masahiro , Tomita Masaru
Published: May 2020

Predictions of distant cancer metastasis based on gene signatures are studied intensively to realise precise diagnosis and treatments. Gene selection i.e. feature selection is a cornerstone to both establish accurate predictions and understand underlying pathologies. Here, we developed a simple but robust feature selection method using a correlation-centred approach to select minimal gene sets that have both high predictive and generalisation abilities. A multiple logistic regression model was used to predict 5-year metastases of patients with breast cancer. Gene expression data obtained from tumour samples of lymph node-negative breast cancer patients were randomly split into training and validation data. Our method selected 12 genes using training data and this showed a higher area under the receiver operating characteristic curve of 0.730 compared with 0.579 yielded by previously reported 76 genes. The signature with the predictive model was validated in an independent dataset, and its higher generalization ability was observed. Gene ontology analyses revealed that our method consistently selected genes with identical functions which frequently selected by the 76 genes. Taken together, our method identifies fewer gene sets bearing high predictive abilities, which would be versatile and applicable to predict other factors such as the outcomes of medical treatments and prognoses of other cancer types.

Published: May 2020

Type 1 diabetic patients have lower counts of butyric acid-producing bacteria in the dysbiotic gut microbiome. In this study, we demonstrate that a butyric acid-producing Leuconostoc mesenteroides (L. mesenteroides) EH-1 strain isolated from Mongolian curd cheese can reduce blood glucose and IL-6 in the type 1 diabetic mouse model. L. mesenteroides EH-1 fermentation yielded high concentrations of butyric acid both in vitro and in vivo. Butyric acid or L. mesenteroides EH-1 increased the amounts of insulin in Min6 cell culture and streptozotocin (STZ)-induced diabetic mice. Inhibition or siRNA knockdown of free fatty acid receptor 2 (Ffar2) considerably reduced the anti-diabetic effect of probiotic L. mesenteroides EH-1 or butyric acid by lowering the level of blood glucose. We here demonstrate that Ffar2 mediated the effects of L. mesenteroides EH-1 and butryic acid on regulation of blood glucose and insulin in type 1 diabetic mice.

Purpose

Play is a critical aspect of children's development, and researchers have long argued that symbolic deficits in play may be diagnostic of developmental disabilities. This study examined whether deficits in play emerge as a function of developmental disabilities and whether our perceptions of play are colored by differences in language and behavioral presentations.

Method

Ninety-three children participated in this study (typically developing [TD];
n
= 23, developmental language disorders [DLD];
n
= 24, attention-deficit/hyperactivity disorder [ADHD];
n
= 26, and autism spectrum disorder [ASD];
n
= 20). Children were videotaped engaging in free-play. Children's symbolic play (imagination, organization, elaboration, and comfort) was scored under conditions of both audible language and no audible language to assess diagnostic group differences in play and whether audible language impacted raters' perception of play.

Results

Significant differences in play were evident across diagnostic groups. The presence of language did not alter play ratings for the TD group, but differences were found among the other diagnostic groups. When language was audible, children with DLD and ASD (but not ADHD) were scored poorly on play compared to their TD peers. When language was not audible, children with DLD were perceived to play better than when language was audible. Conversely, children with ADHD showed organizational deficits when language was not available to support their play. Finally, children with ASD demonstrated poor play performance regardless of whether language was audible or not.

Conclusions

Language affects our understanding of play skills in some young children. Parents, researchers, and clinicians must be careful not to underestimate or overestimate play based on language presentation. Differential skills in language have the potential to unduly influence our perceptions of play for children with developmental disabilities.
SD‐IoTR: an SDN‐based Internet of Things reprogramming framework
Authors: Huynh‐Van Dang , Le‐Trung Quan
Published: May 2020

With the rapid emergence of the Internet of Things (IoT), the development of IoT architecture that facilitates network control and remote management is not only an interesting but also challenging research direction. Designing a systematic framework allowing to remotely (re)reprogram heterogeneous IoT devices requires stringent technical challenges on the interoperability, the scalability and the adaptability. Recently, software defined network (SDN)‐based technologies have been considered as a dominant solution for the IoT network architecture. In this study, the authors firstly review current state‐of‐the‐art approaches of SDN solutions and existing efforts on remote (re)programming IoT systems. The literature review figures out current leading‐edge technologies on SDN‐based solutions and over‐the‐air (OTA) reprogramming approaches in IoT systems as well as indicates the existing challenges that encourage conducting more and more appropriate solutions to fulfil the requirements of the future Internet. Then, a framework called SD‐IoTR (software defined IoT reprogramming) is proposed. The proposed SD‐IoTR framework is based on the SDN architecture and intensively focuses on OTA programming IoT systems. This framework is designed to deal with high demands for dynamic adaptability and scalability. Finally, two case studies are also presented as proofs‐of‐concept that convince the feasibility of applying the proposed framework to real‐world deployments.
Study on the transformation and microstructure evolution during hot-charging rolling process of a weathering steel
Authors: Liu Man , Xu Guang , Chen Guanghui , Wang Zhoutou
Published: May 2020

The effect of hot-charging temperature (HCT) on the transformation and microstructure evolution of a weathering steel was investigated by metallography and dilatometry. The results show that the microstructure consisted of ferrite and pearlite in all specimens when the HCT was between 500 ∼ 850 °C. The difference was that pearlite amount increased obviously at 750 °C, which is detrimental to the plasticity of steels. The reason for more pearlite is that ferrite and austenite coexisted at 750 °C, which belongs to the dual-phase region temperature. The reversed transformation of ferrite to austenite happened and the pre-existing austenite became coarse during the secondary austenization. The carbon content in fine reversed austenite was relatively low, while the coarse austenite contained higher carbon content, which decomposed into blocky pearlite in the final cooling process. Therefore, to obtain the desirable ferrite phase, the HCT of about 750 °C should be avoided. The results provide theoretical reference for optimizing hot-charging rolling process parameters.

Published: May 2020

The aim of the study was to evaluate the remission rate with short-term
premixed insulin therapy in newly diagnosed type 2 diabetes outpatients and
investigate predictors contributing to the remission rate. A 5-year
prospective study was conducted with a total of 170 patients enrolled.
Patients were treated with premixed insulin monotherapy or insulin in
combination with one or two oral drugs. After glucose levels were well
controlled, insulin and oral drugs were discontinued in a stepwise manner.
The prolonged and partial remission rates were calculated and the possible
factors contributing to remission were also analyzed. A total of 164
subjects completed the research study. The prolonged remission, partial
remission and non-remission rates at the 5-year follow-up were 9.8, 59.8,
and 30.5%, respectively. The remission rate was negatively
correlated with disease duration (r=0.39). The combined rate of
remission (prolonged and partial remission) significantly decreased when the
duration was longer than 16 days, and reduced to approximately 50%
after 1 month. Moreover, 75% of prolonged remission patients had
duration of < 16 days. At the 5-year follow-up, the
prolonged remission rate was 9.8% and the partial remission rate was
59.8%. Furthermore, the duration after diagnosis is an independent
predictor of remission rate, and initiation of short-term premixed insulin
therapy within the first 16 days of diabetes diagnosis is very important for
remission. This is the first study to evaluate the remission rate associated
with short-term premixed insulin therapy in recently diagnosed type 2
diabetes outpatients. At the 5-year follow-up, the prolonged remission rate
was 9.8% and the partial remission rate was 59.8%. The
duration of diabetes was identified as an independent predictor of drug-free
remission. The initiation of short-term premixed insulin therapy within 15
days of diabetes onset is particular importance for remission.
Die Opioidkrise in den USA: Ausmaß, Ursachen,
Gegenmaßnahmen und die europäische Situation im
Vergleich
Authors: Preuss Ulrich W. , Wurst Friedrich M. , Wong Jessica Wei Mooi
Published: May 2020

Der Opioid-Missbrauch und die Todesfälle durch Überdosierung
haben in den USA krisenartige Ausmaße angenommen. Allein im Jahr
2017 starben mehr als 47 000 Amerikaner an einer Überdosis
von Opioiden, und die Letalität ist auch in den Folgejahren auf
einem hohen Niveau, da der Konsum synthetischer Opioide (z. B.
Fentanyl-Derivate) in den letzten 5 Jahren erheblich zugenommen hat. Zur
Bewältigung der Krise wurden mehrere Maßnahmen
vorgeschlagen, darunter Programme zur Überwachung
verschreibungspflichtiger Medikamente, Missbrauchs-verhindernde
Opioid-Formulierungen, kognitive verhaltenstherapeutische und
medikamentengestützte Ansätze und die Verteilung von Naloxon
zur Behandlung von Opioid-Überdosierungen – mit bisher eher
begrenztem Erfolg. Im Vergleich dazu gab es in mehreren Ländern
Europas im letzten Jahrzehnt einen Anstieg der Verschreibungen von Opioiden.
Die Letalität durch Opioide ist jedoch deutlich geringer als in den
USA. Gründe für diese Unterschiede können auf
unterschiedliche Zulassungen, Verschreibungsregeln (z. B. Deutsche
Leitlinien zur LONTS, Update 2019) und bessere Implementierung von
Qualitätsmaßnahmen zurückzuführen sein. In
den USA erleichtert die Konzentration auf die medikamentöse
Behandlung von Schmerzen anstatt der Therapie von psychosozialem Stress die
Verschreibung von Opioiden. Außerdem ist MAT/OAT
(medikamentös- oder opioidgestützte Substitutionstherapie)
in vielen europäischen Ländern, insbesondere in
ländlichen Gebieten, möglicherweise häufiger und
umfassender verfügbar als in den USA.
