Published: November 2018

Growth and production models are widely used to predict yields and support forestry decisions. Artificial Neural Networks (ANN) are computational models that simulate the brain and nervous system human functions, with a memory capable of establishing mathematical relationships between independent variables to estimate the dependent variables. This work aimed to evaluate the efficiency of eucalypt biomass modeling under different spacings using Multilayer Perceptron networks, trained through the backpropagation algorithm. The experiment was installed in randomized block, and the effect of five planting spacings was studied in three blocks: T1 – 3.0 x 0.5 m; T2 – 3.0 x 1.0 m; T3 – 3.0 x 1.5 m; T4 – 3.0 x 2.0 m e T5 – 3.0 x 3.0 m. A continuous forest inventory was carried out at the ages of 48, 61, 73, 85 and 101 months. The leaf area, leaf perimeter and specific leaf area were measured at 101 months in one sample tree per experimental unit. Two thousand ANN were trained, using all inventoried trees, to estimate the eco-physiological attributes and the prognosis of the wood biomass. The artificial neural networks modeling was adequate to estimate eucalypt wood biomass, according to age and under different spacings, using the diameter-at-breast-height and leaf perimeter as predictor variables.
Wojenna proza Wiktora Astafiewa a problem nienawiści i przebaczenia
Authors: Popiel-Machnicki Wawrzyniec 
Published: November 2018

Viktor Astafyev was an outstanding Russian writer and a representative of ”village prose”. In his oeuvre, along with works on the question of “man and nature”, we may find numerous important works concerning the subject of war. Astafyev fought in WWII, which left him with some unhealed wounds. In his novels about this 'Great Patriotic War', the dominating pacifist humanism triggered the first depiction of German soldiers through the prism of Christian mercy in Russian literature. The attempt to analyze the novel The Cursed and the Slain is very relevant in light of our present reality, full of news of new military conflicts, including that in eastern Ukraine.
Из наблюдений над текстом утреннего чтения на четверг Великой недели в Архангельском Евангелии 1092 года
Authors: Szwed Zofia 
Published: November 2018

The article is an attempt to analyze the text of the morning reading for Holy Thursday in the 1092 Archangelsk Gospel referenced to the oldest Slavonic traditions of the Holy Bible translations. So far, researchers have focused on the morning reading for Holy Wednesday, which played an important role in the study of the complete edition of Aprakos Gospel. Less attention has been paid to the reading for Holy Thursday, a text which although textologically close to the reading for Holy Wednesday, is very different in the lexical dimension.
Chemical Composition Refining of Bioactive Glass for Better Processing Features, Part I
Authors: Hmood Firas , Goerke Oliver , Schmidt Franziska 
Published: November 2018

Abstract
Bioactive glass is an emerging research area for many scientists around the world. A large processing window combined with high bioactivity are anticipated features for such kind of glass. In fact, both features depend upon the glass network connectivity (NC). A good bioactive glass has a network that ensures a balance between the processing properties and the bioactivity. This study aims at developing a new chemical composition based on that of ICIE16 bioactive glass. Therefore, new compositions were investigated by introducing boron oxide and magnesium oxide with different molar ratios ranging from 1 to 3 mol% each to the composition of ICIE16; In addition,Na2O was partially replaced by P2O5. Melt-quenching technique was followed to prepare the bioactive glass. So far, the results have shown that the processing window increases with the proposed modifications. BP3 and BM2 bioactive glasses show the maximum processing window of a round 250 K. The relationship between the chemical composition and the processing window as well as the corresponding bioactivity will be hereafter discussed.
Thalassodendron ciliatum (Cymodoceaceae) in Palau: occurrence, typhoon impacts and changes over time
Authors: Colin Patrick L. 
Published: November 2018

Abstract
The seagrass Thalassodendron ciliatum (Cymodoceaceae) is uncommon in Palau, Micronesia, but remnant beds occur in an area of less than 1 km2 on the northern tip of Velasco Reef, a sunken atoll, plus small areas on its western rim. The ridges are lengthy, consisting of rhizome mat and seagrass up to 1 m high, and 4–8 m wide forming curving elongate shapes (arcs, concentric curves, circles, patches). Most occur on a gently sloping limestone bottom 22–27 m deep, with some as shallow as 15 m on the Western Rim, and ridges sit directly on top of the limestone pavement, with only the weight of mat and its incorporated rock materials holding them in place. Photographic monitoring over time has indicated they are actively eroding on their edges, but the passage of Super Typhoon Haiyan in 2013 caused much greater damage to the beds. Small patches occur in shallow water on the east side of Babeldaob Island slightly behind the fringing reef crest and have not changed significantly over recent decades.
Analysis of Monolithic and Sandwich Panels Subjected To Non-Uniform Thickness-Wise Boundary Conditions
Authors: Vescovini Riccardo , Dozio Lorenzo 
Published: November 2018

Abstract
The analysis of monolithic and sandwich plates is illustrated for those cases where the boundary conditions are not uniform along the thickness direction, and run at a given position along the thickness direction. For instance, a sandwich plate constrained at the bottom or top face can be considered. The approach relies upon a sublaminate formulation,which is applied here in the context of a Ritz-based approach. Due to the possibility of dividing the structure into smaller portions, viz. the sublaminates, the constraints can be applied at any given location, providing a high degree of flexibility in modeling the boundary conditions. Penalty functions and Lagrange multipliers are introduced for this scope. Results are presented for free-vibration and bending problems. The close matching with highly refined finite element analyses reveals the accuracy of the proposed formulation in determining the vibration frequencies, as well as the internal stress distribution. Reference results are provided for future benchmarking purposes.
Triple Consciousness: The Reimagination of Black Female Identities in Contemporary American Culture
Authors: Welang Nahum 
Published: November 2018

Abstract
My article underscores the intermediate existence of black American women between race and gender by stressing the role white patriarchy and black hypermasculinity play in the marginalisation of black female voices and the prioritisation of white women’s interests within and beyond mainstream feminist spaces. In order to legitimise this intermediate existence of black women, my article develops the triple consciousness theory (TCT). Inspired by W.E.B. Du Bois’ concept of double consciousness, TCT argues that black women view themselves through three lenses and not two: America, blackness and womanhood. Black feminists, TCT affirms, are able to reimagine misguided narratives of black womanhood in contemporary American culture by unpacking the complexity of this threefold consciousness. In Bad Feminist, Roxane Gay strives for the inclusion of pluralist voices in the mainstream feminist movement and in Lemonade, Beyonce uses Afrofuturist tropes, reappropriation and gothic imagery to exorcise the generational pain of betrayal by black men and white women. With Insecure, Issa Rae radicalises feminist theory by critiquing archetypes attached to black womanhood and in Marvel’s Black Panther, not only do black women possess the unprecedented agency to shape their own identities on their own terms, there is also an existential reconnection with their past.
The Politics of Unification in a Fragmented World: Metapopulism and the Precariat
Authors: Hauser Michael 
Published: November 2018

Abstract
Neoliberal capitalism intensified the social fragmentation, which resulted in the upswing of heterogeneous communities without a unifying meta-language that was liberal universalism of citizenship. Our society shows “paralogical” traits and paralogy reverberates in the new populist policy I call metapopulism (Trump, Putin, etc.)-witness their inconsistencies. Metapopulism establishes unifying principles as a substitute of liberal universalism. These are allegory and the Real. An allegorical signifier (“patriotism” etc.), which is separated from the signified (the meaning), is a common representation of heterogeneous communities and simultaneously maintains their paralogy. The Real appears as the signifier that is excluded from “correct” liberal discourse and promises to enhance the experience of a system’s failures by attributing a social meaning to it (sublimation). These principles work on the condition that their promises are permanently thwarted and deferred, which is their spectrality. However, another type of unification may be feasible. It is a unifying discourse and practise that is grounded in a specific position of the “precariat” as the hegemonical class as formed by neoliberal capitalism (the Lukacsian concept). Here, a unification is borne by the praxis of sublimation.
The strong Fatou property of risk measures
Authors: Chen Shengzhong , Gao Niushan , Xanthos Foivos 
Published: November 2018

AbstractIn this paper, we explore several Fatou-type properties of risk measures. The paper continues to reveal that the strong Fatou property,whichwas introduced in [19], seems to be most suitable to ensure nice dual representations of risk measures. Our main result asserts that every quasiconvex law-invariant functional on a rearrangement invariant space X with the strong Fatou property is (X, L1) lower semicontinuous and that the converse is true on a wide range of rearrangement invariant spaces. We also study inf-convolutions of law-invariant or surplus-invariant risk measures that preserve the (strong) Fatou property.
Complex method for calculating total serum calcium concentration
Authors: Eremenko Natalia N. , Shikh Eugenia V. , Serebrova Svetlana Y. 
Published: November 2018

Abstract

Background
Calcium drugs are analogs of endogenous substances. The baseline concentration of endogenous substances in the body and homeostasis mechanisms of regulation make the bioavailability and bioequivalence (BE) evaluation of these drugs very difficult. The aim of the study was to assess the pharmacokinetic parameters of calcium in the studies of comparative bioavailability combined with the assessment of homeostatic regulation mechanisms.

Methods
The study included 42 healthy male volunteers. We studied the composition of 1000 and 1200 mg of calcium, and 800 and 1000 IU of cholecalciferol. Blood sampling was carried out at 8 a.m. and 0.5, 1, 2, 3, 4, 6, 8 h after administering the drugs. Calcium pharmacokinetic parameters were measured: the area under the curve (AUC) “concentration-time”, and maximum concentration (Cmax) in volunteers. The excretion of calcium in urine in terms of creatinine clearance and parathyroid hormone (PTH) levels was assessed. The maximum excretion of calcium was converted to creatinine (calcium/creatinine). Enzyme-linked immunosorbent assay (ELISA) was used to determine the PTH and the o-cresolphthalein method to quantitatively measure the total calcium serum and urine.

Results
Results indicated that both the AUC and the excretion of calcium are comparable, and the differences are not statistically significant, p>0.05 (the ratio of calcium and creatinine in the urine maintained within physiological levels). The comparable dynamics of PTH concentration is an indirect measure of the amount of absorbed calcium.

Conclusions
The study demonstrates that, along with the standard way of calculating the area under the curve “concentration-time” (total calcium in serum), it is important to assess the calcium excretion in urine in terms of creatinine excretion, as well as focusing on the changes in the PTH levels in volunteers, which could be considered as a marker of the calcium level in the blood.
Estimating Case-Fatality Reduction from Randomized Screening Trials
Authors: Saha Sudipta , Liu Zhihui (Amy) , Saarela Olli 
Published: November 2018

Abstract
In randomized cancer screening trials where asymptomatic individuals are assigned to undergo a regimen of screening examinations or standard care, the primary objective typically is to estimate the effect of screening assignment on cancer-specific mortality by carrying out an ’intention-to-screen’ analysis. However, most of the participants in the trial will be cancer-free; only those developing a genuine cancer that is screening-detectable can potentially benefit from screening induced early treatments. Here we consider measuring the effect of early treatments in this partially latent subpopulation in terms of reduction in case fatality. To formalize the estimands and identifying assumptions in a causal modeling framework, we first define two measures, namely proportional and absolute case-fatality reduction, using potential outcomes notation. We re-derive an earlier proposed estimator for the former, and propose a new estimator for the latter motivated by the instrumental variable approach. The methods are illustrated using data from the US National Lung Screening Trial, with specific attention to estimation in the presence of censoring and competing risks.
Stressors and Stress Responses in Cystic Fibrosis
Authors: Bebok Zsuzsa , Fu Lianwu 
Published: November 2018

Abstract
Cystic fibrosis (CF) is a life-shortening, genetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR). The primary cause of CF is reduced CFTR-mediated chloride and bicarbonate transport, due to mutations in CFTR. However, inflammation and persistent infections influence clinical outcome. Cellular stress response pathways, such as the unfolded protein response (UPR) and the integrated stress response (ISR), referred to here as cellular stress response pathways (SRPs), contribute to the pathology of human disorders. Multiple studies have indicated activation of SRPs in CF tissues. We review our present understanding of how SRPs are activated in CF and their contribution to pathology. We conclude that reduced CFTR function in CF organs establishes a tissue environment in which internal or external insults activate SRPs. SRPs contribute to CF pathogenesis by reducing CFTR expression, enhancing inflammation with consequent tissue remodeling. Understanding the contribution of SRPs to CF pathogenesis is crucial even in the era of CFTR “modulators” that are designed to potentiate, correct or amplify CFTR function, since there is an urgent need for supportive treatments. Importantly, CF patients with established pathology could benefit from the targeted use of drugs that modulate SRPs to reduce the symptoms.
Rational design of an improved photo-activatable intein for the production of head-to-tail cyclized peptides
Authors: Böcker Jana K. , Dörner Wolfgang , Mootz Henning D. 
Published: November 2018

Abstract
Head-to-tail cyclization of genetically encoded peptides and proteins can be achieved with the split intein circular ligation of peptides and proteins (SICLOPPS) method by inserting the desired polypeptide between the C- and N-terminal fragments of a split intein. To prevent the intramolecular protein splicing reaction from spontaneously occurring upon folding of the intein domain, we have previously rendered this process light-dependent in a photo-controllable variant of the M86 intein, using genetically encoded ortho-nitrobenzyltyrosine at a structurally important position. Here, we report improvements on this photo-intein with regard to expression yields and rate of cyclic peptide formation. The temporally defined photo-activation of the purified stable intein precursor enabled a kinetic analysis that identified the final resolution of the branched intermediate as the rate-determining individual reaction of the three steps catalyzed by the intein. With this knowledge, we prepared an R143H mutant with a block F histidine residue. This histidine is conserved in most inteins and helps catalyze the third step of succinimide formation. The engineered intein formed the cyclic peptide product up to 3-fold faster within the first 15 min after irradiation, underlining the potential of protein splicing pathway engineering. The broader utility of the intein was also shown by formation of the 14-mer sunflower trypsin inhibitor 1.
A theoretical framework for using humor to reduce the effects of chronic stress on cognitive function in older adults: An integration of findings and methods from diverse areas of psychology
Authors: Mallya Sasha , Reed Maureen , Yang Lixia 
Published: November 2018

AbstractThis paper synthesizes the literature on cognitive aging, emotion regulation, and humor, to provide a theoretical framework for the utility of humor in promoting successful cognitive aging. Many older adults experience some degree of cognitive decline, which is associated with reductions in functional status, independence, and overall quality of life. These losses can result in considerable stress that is chronic in nature. The following discussion proposes humor as a technique that older adults may use to reduce stress and protect cognitive abilities. Humor here is described as a form of cognitive reappraisal, allowing older adults to reappraise daily stressors. Further, it is speculated that humor’s protective value is in the reduction of chronic activation of the physiological stress response systems, which in turn may protect functional integrity of the hippocampus and prefrontal cortex. Because older adults appear to have difficulty solving more complex jokes, we propose that low complexity, self-enhancing humor may be the most useful form of humor for older adults.
Neurotransmittergesteuerte Rezeptoren in neuem Licht: Optische Methoden zur Kontrolle physiologischer Funktion
Authors: Reiner Andreas 
Published: November 2018

Zusammenfassung
Neurotransmittergesteuerte Rezeptoren sind auf vielfältige Weise an der synaptischen Signalleitung und Modulation beteiligt. Am Beispiel der Glutamatrezeptoren wird schnell deutlich, dass diese Rezeptorfamilien eine enorme Diversität aufweisen und es daher eine große Herausforderung bleibt, die unterschiedlichen Funktionen nah miteinander verwandter Rezeptorsubtypen aufzuklären. Pharmakologische und genetische Methoden werden zunehmend durch optogenetische Ansätze ergänzt, welche es erlauben, das Rezeptorsignaling mit Licht zu manipulieren. Am Beispiel der Glutamatrezeptoren lege ich dar, wie kovalent verankerte photoschaltbare Liganden genutzt werden können, um einzelne Rezeptorsubtypen mit hoher räumlicher und zeitlicher Präzision in ausgewählten Zellen zu kontrollieren. Mit diesen und ähnlichen Techniken eröffnen sich neue, vielversprechende Möglichkeiten, die Funktion bestimmter Rezeptoren im Nervensystem zu untersuchen.
Interartery discordance in fetuses with growth restriction
Authors: Mackeen A. Dhanya , Ross John W. , Betz Alexandria , Feng Wen , Bringman Jay J. , Paglia Michael J. 
Published: November 2018

Abstract
OBJECTIVES: Our objectives were two-fold: 1) to determine the frequency of discordant umbilical artery Doppler systolic to diastolic (S/D) ratios in the individual umbilical arteries of growth-restricted fetuses and 2) to examine the impact of the frequency of discordance on clinical outcomes. METHODS: This was a prospective, observational study of growth-restricted fetuses. Doppler velocimetry was performed weekly and two S/D ratios were obtained for each fetal umbilical artery. Inter-artery discordance was defined as a difference in measurement categories (i.e., normal, elevated, absent, reversed) between the arteries. The number of abnormal measurements per visit was summed to 0-4 out of 4 values. A composite average number of abnormal Doppler measurements was calculated and fetuses were stratified based on degree of average number of abnormalities in increments of 25%: 0-<25%, 25-<50%, 50-<75%, and 75-100% abnormality. RESULTS: Of a total 241 fetuses (1762 visits), 110 (45.6%) had abnormal UAD flow and 189 (66%) demonstrated discordance. Abnormal values were noted in only one artery in 53% (n=151) of visits. Fetuses with any abnormal Doppler testing had smaller birthweights compared to fetuses with consistently normal testing (2485g vs 2623g, p <0.01); birthweight decreased as composite average of abnormal measurements increased (p = 0.03). CONCLUSION: The majority (66%) of fetuses with abnormal testing demonstrated UAD discordance. Up to 53% of fetuses could have been misdiagnosed if only one artery was tested. Fetuses with a higher frequency of Doppler abnormalities had lower birthweights. We propose obtaining two measurements from each umbilical artery in growth-restricted fetuses.
Risk related brain regions detection and individual risk classification with 3D image FPCA
Authors: Chen Ying , Härdle Wolfgang K. , He Qiang , Majer Piotr 
Published: November 2018

Abstract
Understanding how people make decisions from risky choices has attracted increasing attention of researchers in economics, psychology and neuroscience. While economists try to evaluate individual’s risk preference through mathematical modeling, neuroscientists answer the question by exploring the neural activities of the brain. We propose a model-free method, 3-dimensional image functional principal component analysis (3DIF), to provide a connection between active risk related brain region detection and individual’s risk preference. The 3DIF methodology is directly applicable to 3-dimensional image data without artificial vectorization or mapping and simultaneously guarantees the contiguity of risk related brain regions rather than discrete voxels. Simulation study evidences an accurate and reasonable region detection using the 3DIF method. In real data analysis, five important risk related brain regions are detected, including parietal cortex (PC), ventrolateral prefrontal cortex (VLPFC), lateral orbifrontal cortex (lOFC), anterior insula (aINS) and dorsolateral prefrontal cortex (DLPFC), while the alternative methods only identify limited risk related regions. Moreover, the 3DIF method is useful for extraction of subjective specific signature scores that carry explanatory power for individual’s risk attitude. In particular, the 3DIF method perfectly classifies both strongly and weakly risk averse subjects for in-sample analysis. In out-of-sample experiment, it achieves 73 -88  overall accuracy, among which 90 -100  strongly risk averse subjects and 49 -71  weakly risk averse subjects are correctly classified with leave-k-out cross validations.
Die Stundentexte zu Seiten der Nut auf der Innenseite des Deckels des inneren Sarges Milano E 0.9.40147 eines Peftjau(em)auuiaset
Authors: Graefe Erhart 
Published: November 2018

Summary
Publication of the inner face of the cover of the inner coffin Milano E 0.9.40147 belonging to an untitled . It contains short awakening-texts for the sake of Osiris (e. g., the owner of the coffin) arranged as the 12 hours of day and night. The hours are represented as kneeling goddesses in adoration bearing a sun-disk on their heads for the day or a star for the night. The texts of both sides are of different types, the hours of the day being called “embodiment” of Horus and those of the night “doors”. The composition is the same as on the sarcophagi of the Napatan kings Anlamani and Aspelta. To date the version from the Milano coffin has only been dealt with en passant.
