Impact of hypoxia on consumption of Baltic cod in a multispecies stock assessment context

Summary The Baltic Sea is characterised by a heterogeneous oceanographic environment. The deep water layers forming the habitat of Baltic cod (Gadus morhua callarias L.) are subjected to frequently occurring pronounced anoxic conditions. Adverse oxygen conditions result in physiological stress for organisms living under these conditions. For cod e.g. a direct relationship between oxygen availability and food intake with a decreasing ingestion rate at hypoxia could be revealed. In the present study, the effects of oxygen deficiency on consumption rates were investigated and how these translate to stock size estimates in multi-species models. Based on results from laboratory experiments, a model was fitted to evacuation rates at different oxygen levels and integrated into the existing consumption model for Baltic cod. Individual mean oxygen corrected consumption rates were 0.1–10.9% lower than the uncorrected ones. At the currently low predator stock size, however, the effect of oxygen-reduced consumption on the total amount of eaten prey biomass and thus predation mortalities was only marginal. But should successful management lead to higher cod stock sizes in the future, then total predation mortalities will greatly increase and thus improved precision of these estimates would be valuable for the assessment of prey stocks.
Glucose and Insulin Responses to Glucagon Injection in Dairy Cows with Ketotis and Fatty Live

Summary The purpose of this investigation was to study the metabolic situation in clinical cases of bovine ketosis and to diagnose additional diseases. Extensive clinical examination, clinical biochemistry, haematology and fine-needle aspiration biopsy Of liver was performed on 17 ketotic and eight control dairy cows in the field, and on seven hospitalized hyperketonaemic fatty liver patients. Additional findings in the ketotic group were heat (n = 7), indigestion (n = 5), endometritis (n = 2), cystic ovaries (n = 1), and mastitis (n = 1), and in the fatty liver group displaced abomasum (n = 4), abomasal ulcers (n = 3), mastitis (n = 2), laminitis (n = 1), bronchopneumonia (n = 1), and hypomagnesaemia (n = 2). There were no additional findings in the control group. Aspartate aminotransferase (AST) and creatine kinase (CK) were elevated in the ketosis and fatty liver groups. Total bilirubin, gamma-glutamyl transferase (GGT) and glutamate dehydrogenase (GD) were elevated in the fatty liver group and in some animals in the ketosis group. Total bile acid was not different between the groups. The free fatty acid/cholesterol ratio was higher in the fatty liver group compared with the control and ketosis groups. There was no or only slight fatty degeneration of the liver cells in the control and ketosis groups. Glucose and insulin preinjection concentrations and changes from basal values after glucagon injection were significantly lower in the ketosis group if compared with the control group. The responses in the fatty liver animals after glucagon injection were more heterogeneous than in the control and ketosis animals, a sign of disturbance in the metabolic adaptation, which together with high free fatty acid (FFA) levels can lead to fatty liver in cows with concurrent diseases.
Biology of the Water-boatman Krizousacorixa femorata (Heteroptera: Corixidae)

Studies of the life history of Krizousacorixa femorata (Guer.) show that development from ova to adult stages occurs over a span of five nymphal instars. Though the species is polymorphic, having asymmetrical dextral and sinistral males and bisymmetrical females, no significant difference is observed in their life histories. Thus, Krizousa- corixa can be added to four other genera (Corixa, Rhamphocorixa, Palmacorixa, Arctocorixa) of Corixidae which have five nymphal instars in their life history. INTRODUCTION Krizousacorixa femorata ('Guer.) is a species of the Corixidae. Among male members an asymmetry of the terminal abdomen occurs, resulting in dextral and sinistral forms (Peters, 1962). Furthermore, an unusual ratio of these two forms exists in natural populations. For example, a collection of 650 male specimens, seined in the autumn of 1951 from a single area at Lake Zumpango near Mexico City, yielded an approximate ratio of three dextral males to one sinistral male. Similarly, a random sample of 390 males taken from Lake Texcoco yielded an approximate ratio of 15 dextral forms to one sinistral. These proportions of dextral to sinistral males differ from those recorded by Jaczewski (1931) and Hungerford (1948). The former records 31 dextral males to five sinistral males and the latter 183 dextral and 79 sinistral. However, the collections of both these authors include specimens from two or more geographically different popula- tions; hence their data are more useful for a general survey than for determining the proportion of dextral to sinistral males of K. femorata (Guer.) in a natural population. The following life history of the species was observed in studies of the inheritance of this asymmetry and differs in certain essential features from previously reported ob- servations. CHARACTERISTICS OF OVA The eggs of K. femorata are ovoid, measuring 0.35+? 0.09 mm x 0.65? 0.06 mm. At the free end is a soft pointed cap, while at the attached pole is a brown disc-like base (Fig. 1). Freshly laid eggs have an evenly stippled surface texture and are opaque white in color except for the basal disc. EGG-LAYING HABITS The natural habitat afforded by Lake Zumpango, Mexico, had a corixid population composed almost exclusively of K. femorata. Eggs were widely distributed on submerged willow-tree rootlets and on the surfaces of smaller aquatic or semi-aquatic plants. Although in some cases the eggs were deposited closely together in a single row, they were often scattered at random over leaves, stems and roots in the habitat. It would seem that there is no stereotyped pattern of egg de- 197
On the geometry and the topology of parametric curves

We consider the problem of computing the topology and describing the geometry of a parametric curve in Rn. We present an algorithm, PTOPO, that constructs an abstract graph that is isotopic to the curve in the embedding space. Our method exploits the benefits of the parametric representation and does not resort to implicitization. Most importantly, we perform all computations in the parameter space and not in the implicit space. When the parametrization involves polynomials of degree at most d and maximum bitsize of coefficients τ, then the worst case bit complexity of PTOPO is ÕB (nd6 + nd5 τ + d4 (n2 + nτ) + d3 (n2τ + n3) + n3d2τ). This bound matches the current record bound ÕB (d6 + d5 τ) for the problem of computing the topology of a planar algebraic curve given in implicit form. For planar and space curves, if N = max{d, τ}, the complexity of PTOPO becomes ÕB (N6), which improves the state-of-the-art result, due to Alcázar and Díaz-Toca [CAGD'10], by a factor of N10. However, visualizing the curve on top of the abstract graph construction, increases the bound to ÕB (N7). We have implemented PTOPO in maple for the case of planar curves. Our experiments illustrate its practical nature.
Taxonomy of Ixinandria Isbrücker & Nijssen (Loricariidae: Loricariinae) based on morphological and molecular data

from the upper rio Bermejo in southern Bolivia. We used a multivariate morphometric analysis (PrincipalComponents Analysis) and a molecular comparison of the Cytochrome Oxidase I gene to investigate variation among distinctpopulations from the known distribution range of both species. We conclude that the populations are not significantly distinctand do not deserve separate species recognition, and we place
Impact of Influencer Type and Advertisement Disclosure on Perceived Trust, Credibility and Purchase Intention

Influencer marketing is a new type of marketing, in which companies pay individuals with extensive social network for endorsing their products. So far, there is a lack of studies that take into account the joint effects of multiple factors of influencer marketing on consumer behavior, and none of the related studies considers an experimental setting. In this research-in-progress paper, we aim to close this gap. More specifically, we focus on investigating the impact of influencer type and advertisement disclosure on perceived credibility and trustworthiness of the influencer, and consumers’ purchase intention. We develop hypotheses on their individual and collective impact on the task performance, based on previous research, dual-process theory, and affect heuristic. We plan to carry out a laboratory experiment to test our hypotheses.
Bitconch Chain, A Newly Distributed Web Protocol Based on an Innovative Proof of Reputation (PoR) Consensus Algorithm and Eco System

BITCONCH chain proposed an innovative POR (Proof Of Reputation) reputation consensus algorithm, which solved the pain point that the blockchain is difficult to maintain both high throughput and decentralization. Based on social graphs, BITCONCH Chain mathematically models social, time, and contribution activities to build a decentralized reputation system. Each user has the opportunity to establish a high reputation value. The higher the user's reputation, the lower the transaction cost (or even free). The more opportunities that are selected as trust nodes to participate in the consensus, the greater the benefits. High-reputation users are defined as “mutual trust nodes”, and small micro-transactions will start “payment channels” for high-speed offline transactions. The reputation system and system incentive system will effectively promote the continued enthusiasm of business developers and ordinary users, and contribute to the construction of the business ecosystem. Business developers with traffic are more likely to get high reputation values, and the chances of being elected to a trusted full node are higher. Ordinary users can increase reputation by actively engaging in social interactions and actively using business applications in the ecosystem, increasing the chances of being selected as trusted light nodes. The Bitconch chain uses a DAG directed acyclic graph data structure to maintain the system's positive scalability. Support smartphone light node client to resist the decentralization of the system and maintain dispersion. Zero-knowledge verification, latticed data storage, quantum-level encryption algorithms, and improved BVM virtual machines make Bitconch chain more reliable and provide a friendly DApp and sidechain development environment to meet certain applications. Technical requirements for large file storage, low transaction costs, user information protection, sidechain and smart contract iterations, and bug fixes. BITCONCH chain is a decentralized distributed network with no block and no chain, which solves two difficulties in the application of blockchain: scalability and decentralization. Bitconch chain, which can be applied to the commercial application needs of users above 10 million, is the most feasible blockchain ecosystem for high-frequency small micro-transactions and social applications.

Korea Food Research Institute, Songnam 463-749, KoreaAbstractThis study was conducted to investigate yield of extract, total phenolic compounds content, electron donating activity, nitrite scavenging activity, superoxide dismutase like activity of the radish leaves (Raphanus sativus L.) extracts. Radish leaves extracts were prepared using water extraction, 50% ethanol extraction and 50% methanol extraction. The yield of Kwandong radish leaves extracts without blanching treatment (DRLK) was 26.56∼32.56% and the extract yield of Minongdanbaek radish leaves without blanching treatment (DRLM) was 34.34∼36.90%. On the other hand, the yield of samples with blanching treatment was a lower range value of 18.70∼23.56% than samples without blanching treatment. In the total contents of phenolic compound, samples with and without blanching treatment were 49.1∼59.4 mg/g and 53.41∼62.08 mg/g, respectively. Minongdanbaek radish leaves extracts (DRLM, BDRLM) showed higher contents value than Kwandong radish leaves extracts (DRLK, BDRLK) in the total phenolic compounds. Samples without blanching treatment showed electron donat-ing activity above 80%, nitrite scavenging activity of 36.63～51.17% and superoxide dismutase like activity of 38.53～45.38%. Generally, Kwandong samples showed a little higher activity more than Minongdanbaek sam-ples in the electron donating activity, nitrite scavenging activity and superoxide dismutase like activity. Also, radish leaves extracts without blanching treatment showed high physiological activities. Key words: radish leaves, total polyphenolic compound, electron donating activity, superoxide dismutase
Everything is Connected: From Model Learnability to Guessing Entropy

Guessing entropy is a common choice for a side-channel analysis metric, and it represents the average rank position of a key candidate among all possible key guesses. In the proﬁled side-channel analysis, the guessing entropy behavior can be very informative about the trained or proﬁled model. However, to achieve reliable conclusions about the proﬁled model’s performance, guessing entropy behavior should be stable to avoid misleading conclusions in the attack phase. In this work, we investigate this problem of misleading conclusions from the entropy behavior, and we deﬁne two new concepts, simple and generalized guessing entropy . We demonstrate that the ﬁrst one needs only a limited amount of attack traces but can lead to wrong interpretations about leakage detection. The second concept requires a large (sometimes unavailable) amount of attack traces, but it represents the optimal way of calculating guessing entropy. To quantify the proﬁled model’s learnability, we ﬁrst deﬁne a leakage distribution metric to estimate the underlying leakage model. This metric, together with the generalized guessing entropy results for all key candidates, can estimate the leakage learning or detection when a necessary amount of attack traces are available in the attack phase. By doing so, we provide a tight estimation of proﬁled side-channel analysis model learnability. We conﬁrm our observations with a number of experimental results.
Security Analysis of Olvid's SAS-based Trust Establishment Protocol

In this report, we analyze the security of the trust establishment protocol used in the Olvid messaging protocol. The latter relies on the PV-SAS-MCA message cross-authentication protocol by Pasini an Vaudenay based on short authenticated strings (SAS). In order to make the implementation portable across different platforms, Olvid proposed particular instantiations of the underlying primitives used in PV-SAS-MCA in addition to some other minor modifications. Here, we show that these changes have no impact on the security of the scheme. More precisely, we formally prove that the trust establishment protocol used in Olvid is a secure message cross-authentication protocol. The proof of security is in the random-oracle model and relies on the security of the underlying pseudorandom generator. It also assumes users know each other and have an authentic channel between them.
In Vitro Inhibition of Key Enzymes Related to Diabetes by the Aqueous Extracts of Some Fruits of West Bengal, India

Aqueous extracts of different seasonal as well as less popular but edible indigenous fruits of West Bengal, India were studied for their α-glucosidase and α-amylase inhibitory properties. Of the 22 different species of fruits, sixteen fruits inhibited both the carbohydrate digesting enzymes. Concentrations of the extracts are presented as fresh weight of fruit used to make extract / ml. Very high α-amylase (IC50 value = 5.0 μg/ml) and α-glucosidase (IC50 value = 9.0 μg/ml) inhibitory activity was shown by extracts of Phoenix sylvestris. Achras sapota also showed high α-amylase (IC50 value = 53.0 μg/ml) and α-glucosidase (IC50 value = 56.0 μg/ml) inhibitory activities. During the present study, no correlation could be established between total phenol / flavonoid content and α-amylase / α-glucosidase inhibitory activity. Unweighted pair-group average (UPGA) dendrogram showing interrelationships between the investigated species shows that the fruits can be grouped into two high level clusters. The cluster I brought together Borassus flabellifer and Physalis peruviana having very low α-glucosidase inhibitory activity. The cluster II included fruits with moderate to high α- glucosidase inhibitory activity.
An Exploratory Analysis of Alarming and Reassuring Messages in Twitterverse during the Coronavirus Epidemic

Twitter has become one of the widely used crisis communication tools In the recent coronavirus outbreak, social media users exchange millions of messages ranging from crisis response to awareness creating messages We conduct an exploratory analysis using tweets collected over initial one month of its outbreak to unveil useful trends and gain insights into managing crisis Our findings from the analysis present that both alarming and reassuring messages surface during crisis situations, however, it is the reassurance messages that build confidence in individuals to overcome the distress that an epidemic creates Following the guidelines of Crisis Management, we establish a linguistic based approach to explore the tweets text Our findings provide insights that the gap between the number of alarming and reassuring messages widen as the epidemic spreads Our findings also show that significantly, there exists a cluster of similar messages among the deluge of information Identifying these clusters help manage the crisis situation
Selection Factors determining the Hybrid Approach: a Preliminary Study

The choice of methodology for information system development (ISD) is a significant question faced by information systems (IS) professionals. A sizable body of research details the agile and traditional approaches independently. The choice of approach holds no universal agreement. A hybrid approach combines agile and traditional techniques, implementing multiple methods within one approach. The contextual analysis identified that the hybrid approach is attaining popularity. The investigation of factors ensure an informed, and justified approach can be selected. Prior research debates company culture, individual choice, and natural evolution as selection factors. Researchers have identified the need to find additional factors. This study proposes a design to identify the factors influencing the selection of hybrid. This research will be the first within the field to examine these factors in an Australian context. A matrix in progress aids the purposeful selection of the hybrid approach.
Cytotaxonomic Notes on the Tribe Helieae (Gentianaceae)

Abstract. A survey of all known chromosome counts of gentian tribe Helieae are presented including new reports for ten species. Amongst the novelties are four genera of the Gentianaceae that are reported for the first time, Calolisianthus and Helia (both Helieae), and Schultesia and Zygostigma (both Chironieae). In the Helieae, our results reinforce the hypothesis of Weaver 1969 that two ploidy series occur in the tribe, one polyploid based on n = 20 and one dysploid based on n = 21. The basal chromosome number for the Helieae remains to be determined.
Patient Empowerment and Electronic Health Record Systems Sharing: A Design Perspective

Patient empowerment through health information technology is a relevant area in healthcare transformation; however, research has not adequately addressed how electronic health record (EHR) systems design can enhance this phenomenon in the care process. This study proposes a design artifact (EHR sharing) that focuses on empowering patients and EHR use to achieve patient centered care. Using a sample of 154 in a real-world scenario (diabetes) and a design science approach, we tested and evaluated the effectiveness of our proposed artifact for both the traditional and the current design approaches. The t-test statistics results show that using the current approach, patients are more empowered when they have access to their health information, interact with the physicians, have choice options to make decisions, and when the physician blends with patient in a more natural way. Some design principles, contributions and implications to research and practice and avenues for future research are discussed.
Agora: A Privacy-aware Data Marketplace

We propose Agora, the first privacy-aware data marketplace that enables parties to get compensated for contributing data, without relying on a trusted third party. We leverage cryptographic techniques to achieve three security properties: (i) data privacy—raw data remain private except for a function output, (ii) output verifiability—the output is proven to be correct, and (iii) atomicity of payments—parties cannot avoid paying for provided services. Agora is designed as a decentralized blockchain application via smart contracts. We implement a prototype on Ethereum and evaluate its performance in terms of computation overhead and monetary cost.
Modified Secure Hashing algorithm(MSHA-512)

In recent year’s security has become an important role in the ﬁeld of Defense, Business, Medical and Industries. Diﬀerent types of cryptography algorithms has been implemented in order to provide security with high performance. A hash function is a cryptography algorithm without a key such as MD5, SHA-family. Secure hash algorithm which is standardized by NIST as secured hashing in FIPS. In this paper we mainly focus on code optimization and increase the performance of SHA-512. To optimize and increase the performance of SHA-512 we have modiﬁed the algorithm and proposed Modiﬁed Secure hash algorithm(MSHA-512 ). It is a one-way hash function that can process a message to produce a condensed representation called a message di-gest.In this proposed algorithm within the limited rounds (40 rounds instead of 80 rounds) we can obtain exact result which is same as traditional SHA-512 algorithm. By using MSHA-512 algorithm we can reduce the time upto 50% for the same process, which increases the performance of the algorithm and helps to increase the ﬂexibility of server in running streams.The MSHA-512 generates the same hash code as we generate in the SHA-512 for all diﬀerent size of inputs. MSHA-512 is developed and designed to overcome the time complexity of SHA-512 and increase the performance of it by reducing the rounds.
Combining the Case Survey Method and Qualitative Comparative Analysis for Information Systems Research

The case survey method and qualitative comparative analysis (QCA) are two well-established research approaches in a number of research disciplines. They have recently made their way into information systems (IS) research. The case survey method is aimed at comparing previously published case studies, conventionally, using various statistical analysis methods. In turn, QCA relies on set theory, which allows deriving different configurations based on qualitative data corresponding to cases translated into set membership. Several authors have started to combine these two methods. However, so far there is no formalized approach on how to combine them. In this paper, we present a formalized approach to integrate the two methods and demonstrate how this approach can be used to resolve several limitations intrinsic to these methods when being employed on their own. We furthermore discuss the potential of applying our approach for IS research and discuss the proposed approach’s limitations.
