Asset Allocation Strategies: Enhanced by News

The explosive development of electronic media has brought to the market participants thousands of pieces of financial news which are released on different platforms every day. Many news wires published online are editorially controlled and can be relied as factual summary as opposed to fake news or disinformation. These news items provide a rich source of textual information which in a summative way represents the sentiment of the market. The sentiments influence or impact the asset price as well as the volatility of individual assets. In this study we have tested sentiment enhanced daily trading strategies. Alexandria Technology has provided us news sentiment metadata, which is used in this study. We have also resorted to `asset filters' which we use to restrict the universe of assets chosen for daily trades. We have considered quantified news sentiment and its impact on the movement of asset prices as a second time series data, which is used together with the asset price/return time series data. Our asset allocation strategy uses Second Order Stochastic Dominance (SSD); see \cite{roman2006portfolio, roman2013enhanced}. Following this modelling paradigm we compute daily trade schedules using a time series of historical equity price data. In contrast to classical mean-variance method this approach improves the tail risk as well as the upside of the return. In our recent research we have introduced news sentiment indicators such as News RSI (NRSI) and Derived RSI (DRSI) filters. These filters restrict the choice of asset universe for trading. Consistent performance improvement achieved in back-testing vindicates our approach.
Development and Application of a Methodology to Determine Free Ferulic Acid and Ferulic Acid Ester-Linked to Different Types of Carbohydrates in Cereal Products

ABSTRACT Ferulic acid bioavailability is dependent on its form present in food. This necessitates a methodology to quantify different groups of ferulic acid derivatives in food products, especially cereal-based products. The aim of the proposed methodology is to separate and quantify ferulic acid ester-linked to mono- and/or oligosaccharides (OF), to soluble polysaccharides (SPF), and to insoluble polysaccharides (IPF) as well as in its free form. Development and partial validation of this method, which was widely based on liquid/liquid extraction and precipitation steps, was performed using characterized standard materials isolated from corn bran. As the determination of OF was one of the major goals of this methodology, three different feruloylated mono- and oligosaccharides were used for method development and validation. To determine the accuracy of the method, ferulic acid–containing standard materials added to a starch matrix were extracted and separated according to the developed protocol. The sepa.
Morphological analysis of Spirulina sp. NCIM 5143 and Nostoc ellipsosporum NCIM 2786 and comparative characterization of associated enzymes through in silico approach

Cyanobacteria are the only prokaryotes that can utilize energy sources from sunlight, electrons from water, carbon from the air, and have the capability of fixing nitrogen. The characterization of various cyanobacteria reveals the performance as well as growth differences when compared among different genus of cyanobacteria, which emphasizes the value of characterization in the cellular grounds. In this paper, we have performed a comparative study on the morphology, growth pattern, physiochemical properties as well as structural features of Spirulina sp. NCIM 5143 and Nostoc ellipsosporum NCIM 2786. The comparison is performed through microscopic images, FESEM and statistical study of cell growth by ANOVA. In silico approach was also carried out on the two enzymes present in both the cyanobacteria, Cyanophycin synthestase (EC: 6.3.2.29) and Nitrate reductase (EC: 1.7.1.1) by studying the physicochemical properties, sequential features and structural modeling. A descriptive profile study was completed on these microorganisms and their proteins that may help to interpret the molecular mechanism of the enzymatic reaction of 1, 3-Propanediol (PDO) production in the future.
Leaf spot on switch grass (Panicum virgatum), symptoms of a new disease caused by Bipolaris oryzae

Switch grass (Panicum virgatum) is a native, perennial warm-season grass used for hay, summer grazing, soil conservation, and wildlife habitat. It is also being developed as a biomass crop for renewable energy. A previously unreported leaf-spot disease on switch grass was observed in North Dakota plantings. From 1999 to 2002, a fungus was consistently isolated from leaf spots on switch grass. It was identified as Bipolaris oryzae (teleomorph: Cochliobolus miyabeanus). Conidial morphology agreed with that of B. oryzae, and comparison of DNA sequences from glyceraldehyde-3-phosphate dehydrogenase also indicated that the isolates were B. oryzae. Greenhouse pathogenicity tests confirmed the ability of B. oryzae to cause symptoms of leaf spot on switch grass. This is the first time that B. oryzae, a common pathogen on rice (Oryza sativa), is reported to cause a disease on switch grass. This pathogen has the potential to diminish yields of switch grass under intensive plantings for high biomass production, particularly if a susceptible cultivar is seeded over a wide area. Additionally, Bipolaris zeae (teleomorph: Cochliobolus zeae) was isolated from switch grass, a new host for this fungus, and is herein reported for the first time from the United States.
Characterization of [3H]‐N‐[R‐(2‐ Benzothiazolyl)thio‐2‐propyl]‐2‐chloroadenosine ([3H]‐NNC 21‐0136) binding to rat brain: Profile of a novel selective agonist for adenosine A1 receptors

N‐[R‐(2‐Benzothiazolyl)thio‐2‐ propyl]‐2‐chloroadenosine (NNC 21‐0136) is a novel adenosine agonist with neuroprotectant properties in rodent models of focal and global ischemia that exhibits diminished cardiovascular side effects when compared to reference A1 agonists [Sheardown et al., 1995]. NNC 21‐0136 is shown to be a potent agonist of adenosine A1 receptors showing around 60‐ and 30‐fold selectivity over adenosine A2A and A3 receptors, respectively. In order to further characterize the central nervous system molecular target for NNC 21‐0136, the compound has been radiolabeled and utilized in receptor binding experiments. In vitro receptor autoradiography with [3H]‐NNC 21‐0136 revealed high levels of receptors in the CA1 region of the hippocampus, the granule cell layer of the cerebellar cortex, and moderate uniform levels throughout the cerebral cortex. [3H]‐NNC 21‐0136 binding to rat cerebral cortical membranes was reversible and saturable (Bmax = 0.98 ± 0.04 pmol/mg protein) to a high affinity site (Kd = 1.16 ± 0.06 nM) as determined by saturation binding experiments. [3H]‐NNC 21‐0136 binding was sensitive to guanosine‐5′‐O‐(3‐thio)triphosphate‐γ‐S and enhanced by the presence of divalent cations (Ca2+ and Mg2+). A highly significant correlation between the affinities of several compounds to displace [3H]‐NNC 21‐0136 binding as compared to [3H]‐N‐R‐(2‐phenylisopropyl)adenosine ([3H]‐R‐PIA) binding to adenosine A1 receptors in rat cortical membranes was observed. We conclude that [3H]‐NNC 21‐0136 is a new, selective radioligand for adenosine A1 receptors. Drug Dev. Res. 42:86–97, 1997. © 1997 Wiley‐Liss, Inc.
ADENINE UPTAKE BY LAMINA PROPRIA CELLS IN THE INTESTINAL MUCOSA OF RATS AND MICE, WITH SPECIAL REFERENCE TO RETICULUM CELLS

The incorporation patterns of [14C]adenine ([14C]A) and, as control, [3H]thymidine ([3H]TdR) by proliferative cells in the intestinal mucosa of rats and mice were studied by the autoradiographic technique. The animals received 3 daily, subcutaneous injections of the isotopic markers (1μCi/g body weight each) and examinations were made 3hr after the last injection.The most striking finding was a strong labeling with [14C]A of a portion of non-lymphoid lamina propria cells (LPC) in the core of jejunal villi, in contrast to weak labeling of the epithelial cells with this isotopic marker. Furthermore, the labeling of epithelial cells decreased in intensity to a large extent following RNase treatment. In contrast, the silver grains over the LPC did not markedly decrease in number after RNase treatment and the cells still remained heavily labeled. Following extraction of DNA with DNase treatment, the heavy labeling of LPC vanished completely. This provides evidence for the incorporation of [14C]A into DNA of the LPC to a great extent.The overall patterns of [3H]TdR labeling of mucosal cells, on the other hand, was characterized by fairly uniform labeling of proliferative cells and no great difference in the labeling intensity was recognized between the epithelial cells and the LPC of jejunal villi.The results mentioned above were discussed in relation to the peculiar adenine metabolism of the LPC. It was suggested that the LPC have a limited capacity for de novo adenine synthesis and because of this they were labeled with [14C]A to a greater degree.The LPC which exhibited heaviest labeling with [14C]A had the same morphological characteristics as those of the primitive reticular (or reticulum) cells, which have been described by Maximow (9) and Marshall (8) as undifferentiated mesenchymal cells. The similarity of the former cells to the latter cells was discussed.
Radioimmunoassay and enzyme-linked immunosorbent assay techniques as aids to studying pituitary hormones and improving reproductive management of the one-humped camel

Abstract Little research has been undertaken on the reasons that fertility in the one-humped camel is low. Monitoring of various hormones, in particular the pituitary hormones (including luteinizing hormone, follicle stimulating hormone, prolactin and growth hormone) by techniques such as radioimmunoassay and enzymeimmunoassay would help in the understanding of the physiological processes of reproduction. In order that these hormones can be monitored, however, they need to be isolated and characterized. This paper describes such isolation and characterization and then looks at some practical aspects of the application of immunoassays.
Central Bank Digital Currency with Adjustable Interest Rate in Small Open Economies

We examine the economic consequences of an interest-bearing design of the Central-Bank Digital Currency (CBDC), and extend the discussion to an open-economy context with trade and capital flows. We use a dynamic stochastic general equilibrium (DSGE) model to simulate a baseline scenario with only a primary monetary policy rule, and two counter-factual scenarios with a primary monetary rule together with a secondary CBDC rule associated with adjustable interest-bearing CBDC — the price rule or the quantity rule. Our simulations show that 1) CBDC with an adjustable interest rate is welfare-improving; 2) a quantity rule delivers the best welfare outcome for society, but with uneven distributional effects between households and financial investors; 3) exchange rate movements and inflation are more stable with the adjustable interest rate; 4) imperfect substitutability between CBDC and bank deposits is the key for the effectiveness of using the CBDC as a secondary monetary policy instrument.
Genetic Transformation of Durum Wheat (Triticum durum Desf.) through Particle Bombardment of Scutellar Tissues

This is the first report of the production of transgenic durum wheat. A f transformation system or common wheat through particle bombardment of scutellar tissues of immature embryos was successfully applied to emmer wheat. Three emmer wheats, Triticum durum var. reichenbachii, T. durum var. agricunum and T. aethiopicum Jakubz. , were used in the transformation experiments. The scutellar tissues isolated from immature seeds were bombarded with a plasmid, pDM302 containing the bialaphos-resistant gene (bar) under control of the rice actin 1 gene (Act1) promoter. In T. durum var. agricunum, 25 bialaphos-resistant plants were independently regenerated from each green-spotted calli. On the other hand, no bialaphos-resistant plants were recovered from the other two emmer wheat, T. durum var. reichenbachii and T. aethiopicum. Most regenerated plants grew into mature and fertile plants. The integration and inheritance of the bar gene were confirmed by the PCR amplification and Southern analysis in T0 and T1 plants. All 25 plants showed the positive band of the bar gene. The frequency of transformation was 1.17 % (25 independent transformants/2144 immature embryos).
Allometric growth of chemical body components and several organs in the pig (20–90 kg liveweight)

Abstract The allometric patterns of growth relative to bodyweight or lipid-free bodyweight, of the gross chemical body components and the liver, kidney, small intestine, heart, and biceps femoris muscle were determined for Landrace × (Landrace × Large White) pigs. Fifteen entire-male and 15 female pigs were grown from 20 to 90 kg liveweight, with equal numbers of animals being slaughtered at 20, 55, and 90 kg liveweight, There was little effect of sex of the animal on the relative growth of the body components although the entire males had a heavier right kidney but a lighter biceps femoris at a given empty bodyweight, and a lighter biceps femoris at a set lipid-free empty bodyweight, than the females. The allometric growth coefficients (b) for the growth of water, ash, protein, and lipid relative to the growth of the empty body were 0.93, 0.93, 1.00, and 1.30, respectively. The coefficients (b) for growth of the kidney, liver, small intestine, and heart relative to growth of the empty body (0.81, 0.76, 0.
Laboratory rearing of Cape anchovy Engraulis capensis and South African pilchard Sardinops ocellata through metamorphosis

The first rearings of the Cape anchovy and South African pilchard from the egg through metamorphosis are described. Larvae were fed a variety of laboratory-cultured organisms. The highest growth rates were achieved in experiments in which the calanoid copepod Paracartia africana and cyclopoid Oithonina nana were fed. Data on laboratory growth, mortality, and feeding in the two species are presented.
Analyzing the Effects of Accidental Environmental Impacts: Approaches and Assumptions

Because studies of environmental accidents must be initiated after the fact and because the accidents cannot (or should not) be replicated, sampling cannot be entirely randomized, and investigations involve some degree of confounding and pseudoreplication. The methodological issues relate to consistency in sampling methods and to the adequacy of sampling of levels of environmental disturbance or contamination, while the ecological assumptions derive from spatial and temporal variation in biological resources and the factors that affect them. These methodological issues and ecological assumptions affect study designs based on before-after comparisons and on single-time or multiple-time sampling after an accident. Designs that rest on the assumption of a steady-state equilibrium in resource-environment relationships (baseline and time-series designs) must be interpreted with particular care. Other designs (pre/post paired samples, impact level-by-time, impact trend-by-time) assume only that environmental variations are equivalent among areas and/or contamination levels (a dynamic equilibrium) and are less affected by pseudoreplication. Single-time designs (comparisons between impact and reference sites, between matched paired sites, or over a contamination gradient) have fewer methodological limitations, but assume that other natural factors that may influence the response of a resource are equal among all samples. If measurements of other factors are included in themore » design, covariance analysis may help to reduce this problem. In evaluating the effects of unplanned environmental impacts, post facto study designs that document both initial effects and subsequent recovery (impact level-by-time, impact trend-by-time) or that treat effects as continuous rather than categorical variables (gradient or trend designs) may be more useful than before-after comparisons. 54 refs., 6 figs., 2 tabs. « less
New Pythium Taxa Causing Root Rot on Mediterranean Quercus Species in South-west Spain and Portugal

Pythium spiculum, a recently described new taxon, has been frequently isolated from declining Quercus rotundifolia and Q. suber roots and rhizosphere since 2003 in southern Iberia. In soils of declining Quercus forests this species was found as frequently as Phytophthora cinnamomi which, until now, was the only oomycete described as a Quercus root rot pathogen in the region. Inoculation tests conducted on young Q. rotundifolia plants showed that Py. spiculum is an aggressive root pathogen, although producing severities of symptoms significantly lower than those of P. cinnamomi. This new pathogen could play a role as decline factor in southern Iberia. Another new species, Py. sterilum, was also found to be pathogenic to Quercus roots but there are presently only few records of this organism isolated from rhizosphere of declining oaks in central Spain. More than an active decline factor, this species should be considered as a potential risk for Quercus forests.
Assessing the Unacquainted: Inferred Reviewer Personality and Review Helpfulness

This work examines the question of who is more likely to provide future helpful reviews in the context of online product reviews by synergistically using personality theories and data analytics. It trains a deep learning model to infer a reviewer’s personality traits. This enables analyses to reveal the role of personality traits in review helpfulness among a large population of reviewers. We develop hypotheses on how personality traits are associated with review helpfulness, followed by hypotheses testing that confirms that higher review helpfulness is related to higher openness, conscientiousness, extraversion, and agreeableness and to lower emotional stability. These results suggest the appropriateness of using these five personality traits as inputs for developing a model for predicting future review helpfulness. Based on an ensemble model using supervised classification algorithms, we develop a predictive model and demonstrate its superior performance. Theoretical and practical implications are discussed.
Polymorphism Identification of Pit1 Gene in Indonesian Buff aloes (Bubalus bubalis) and Holstein-Friesian Cows

Pit-1 gene has been identifi ed as the pituitary specifi c transcription factor that regulates the expression of the growth hormone (GH) and prolactin (PRL) genes in the anterior pituitary. The use of polymorphic markers in breeding programmes could make selection more accurate and effi cient. A total of 320 Indonesian buff aloes from four populations and 45 FH cows from nine populations were genotyped for polymorphism of Pit1|Hinf1 gene by the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) methods. The gene polymorphism was detected only in FH ca le. The frequency of AA, AB, and BB genotype was 2%, 44%, and 53% respectively. The frequency of A allel was 25% and B allel was 75%, but no polymorphism was detected in 320 Indonesia buff aloes.
Affinity tags for protein purification.

The affinity tags are unique proteins/peptides that are attached at the N- or C-terminus of the recombinant proteins. These tags help in protein purification. Additionally, some affinity tags also serve a dual purpose as solubility enhancers for challenging protein targets. By applying a combinatorial approach, carefully chosen affinity tags designed in tandem have proven to be very successful in the purification of single proteins or multi-protein complexes. In this minireview, I discuss the key features of the most commonly used affinity tags. I have classified the affinity tags into two significant categories, epitope tags, and protein/domain tags. The epitope tags are generally small peptides with high affinity towards a chromatography resin. The protein/domain tags often time double duty as solubility enhancers while aiding affinity purification. Finally, I discuss protease-based affinity tag removal strategies after purification.
To cannibalize or disperse? Males cannibalize and females disperse in the predatory mite Phytoseiulus persimilis

Cannibalism is a widespread phenomenon in nature, often occurring when food is scarce, for example among predators that have overexploited a local prey population. Instead of cannibalizing, predators can disperse, thereby avoiding being cannibalized or cannibalizing kin-related conspecifics, resulting in inclusive fitness loss. Theory on prey exploitation in ephemeral predator-prey systems predicts that predators may be selected to display prudent predation (‘Milker’ predators) by dispersing early, thus saving food for their remaining offspring. This is especially advantageous when average relatedness in the local population is high. Less prudent predators refrain from dispersing until all prey are exterminated. These prey exploitation strategies may also have repercussions for cannibalism, especially when it is driven by food shortage. We therefore investigated to what extent adult females and males of lines with different dispersal strategies cannibalize or disperse when prey are exterminated. We used two lines of the haplodiploid predatory mite Phytoseiulus persimilis that were selected for early and late dispersal. Using wind tunnels, we observed the behavior of adult predators of these lines, offering conspecific larvae as victims. Our results show that both selection lines behaved similarly but that male predators stayed significantly longer in the patch and engaged more often in cannibalism than females. This is in agreement with differences in their behavior and in their kin-relatedness to the other individuals on the patch. We therefore propose that males and females of haplodiploid species may have different tendencies to cannibalize. 61 AlexandraRevynthi-ch5_Vera-ch1.qxd 20/10/2017 14:50 Page 61

A Safe Doppler Ultrasound-Guided Method for Nasolabial Fold Correction With Hyaluronic Acid Filler.

BACKGROUND Injection of hyaluronic acid filler is a common procedure for nasolabial fold correction. However, it poses a risk of vascular compromise, which can result in skin necrosis and blindness. OBJECTIVE We aimed to examine the facial arterial pathway in real-time using Doppler ultrasound, to avoid arterial complications during filler injections. METHODS Forty patients (80 cases with nasolabial folds; 2 men and 38 women; mean age, 46.5 years (range, 28-72 years)] underwent examination of the facial artery pathway with Doppler ultrasound before hyaluronic acid filler injection. On the basis of the Doppler evaluation results, the filler injection targeted the subdermal, subcutaneous, and deep to submuscular layers by bypassing the facial artery. The efficacy of the filler injection was evaluated for each patient. RESULTS The facial artery was detected lateral to the nasolabial fold in 31% patients, while it was detected at the nasolabial fold in the other cases as follows: subdermal layer in 13% patients, subcutaneous layer in 29% patients, muscular layer in 24% patients, and submuscular layer in 4% patients. The mean Wrinkle Severity Rating Scale score was 3.68 ± 0.76 before injection and 2.28 ± 0.78 3 months after injection. Two patients experienced unilateral bruising of the nasolabial fold, which resolved after 2 weeks without treatment. CONCLUSIONS Doppler ultrasound can be considered as pretreatment tool for the prevention of vascular complications during filler injections to correct nasolabial folds.
