Kiss Pure powers and power classes in recurrence sequences

Let R = R(A, B, RQ,RI) be a second order linear recursive sequence defined by Rn = Ai? n_i + BRn„2 ( n > 1), where A, J5, i? o and i? i are fixed rational integers. In the sequel we assume that the sequence is not a degenerate one, i.e. a//3 is not a root of unity, where a and (3 denote the roots of the polynomial x — Ax — B. The special cases J? (l, 1,0,1) and i? (2,1,0,1) of the sequence R are called the Fibonacci and the Pell sequence, respectively. The squares and other pure powers in sequences R were investigated by many authors . For the Fibonacci sequence C o h n [2] and W y 1 i e [22] showed that a Fibonacci number Fn is a square only when n = 0 ,1 , 2, or 12.

Retrotransposition and Ageing-associated Neuronal Function Decline

The world population is progressively ageing. It is estimated that by 2050, almost onefifth of the world population will be aged 65 years or more. Despite the significant increases in life expectancy observed in the last century, health span remained unchanged. Therefore, people live longer but in suboptimal conditions, which frequently lead to the development of age-related diseases, like neurodegenerative diseases. Understanding the molecular and cellular mechanisms underlying ageing and neurodegeneration is crucial and could provide the means to delay, mitigate or even revert the deteriorating e↵ects associated with age-related neurodegeneration. Recent studies have correlated increased expression of retrotransposable elements (REs) with age, which is likely due to the tendency of RE silencing mechanisms to fail with age. Furthermore, it was reported in flies that young individuals with a neurodegenerative decline had premature expression of REs in their brain. However, it remains unclear whether RE expression and mobilization are the cause or a consequence of the age-associated neuron functional decline. The aim of this dissertation is to determine if RE expression in the central nervous system causes an age-associated neuronal function decline. To answer this, we developed a heterologous and naïve inducible RE system that allows specific expression of a human long interspersed nuclear element 1 (LINE-1 or L1) in Drosophila melanogaster neurons. Negative geotaxis assays were performed in flies aged 2, 20, and 40 days after eclosion to assess the age-associated neurofunctional decline. Results revealed that the forced expression of L1 in neurons throughout lifespan does not a↵ect neuronal function. However, both in vivo and in vitro experiments failed to demonstrate retrotransposition events in the fly. These findings suggest that additional human factors are required in L1 retrotransposition. Future studies will focus on determining retrotransposition

Total phenols and antioxidant capacity in 10 Moroccan pomegranate varieties.

UNLABELLED The study focused on characterizing the 10 major Moroccan cultivars to acknowledge the quality and bioactive compounds of the fruits. The following determinations were assessed: pomegranate fruit maturity index, which truly defines juice taste, as well as organic acids and sugar contents, total phenols, and antioxidant activity of pomegranate juice. The cultivar per se (genotype) behaved as the most influencing factor conditioning pomegranate sugar and organic acids profiles, antioxidant activity, and total phenolics. The assessment of pomegranate chemical compositions implies the great potential of Moroccan cultivars for both fresh market and fruit processing. In fact, the "Hamde" sour cv. seems particularly suitable for juice production because of its high phenolics content. Additionally, the presence of bioactive compounds in pomegranate juices may encourage their consumption for potential health benefits. PRACTICAL APPLICATION The cultivar per se (genotype) behaved as the most influencing factor conditioning pomegranate sugar and organic acids profiles, antioxidant activity, and total phenolics. Given the divergence observed on bioactive compounds concentrations and antioxidant activity among evaluated cultivars, the genotype factor should be considered as the most influencing factor in future breeding programs to enhance the synthesis of beneficial bioactive compounds.
Economic integration and regional patterns of industry location in transition countries

Recent developments in international trade theory predict that increased globalization will be associated with increase locational concentration of particular economic activities, and hence increased specialisation of national and regional economies. Relative little empirical evidence exists on whether these predictions are correct, mainly as far as Central and Eastern Europe is concerned. This paper aims at exploring and analysing the trade-location relationship in five candidate countries, namely Bulgaria, Estonia, Hungary, Romania and Slovenia, during the 1990s. Three empirical evidence will be provided: current trend in spatial development in the face of rapidly increasing trade at national and regional level; factors explaining such patterns and the role played by the economic integration process with the EU in partially or totally shaping such patterns. This paper combines spatial data on GDP, labour force, wages, and other socio-economic indicators included in REGSPEC database to estimate patterns of development at regional level. Particular emphasis will be devoted to understand these patterns in border regions, which may be disproportionately vulnerable to the enlargement process but also have the potential to exploit geographical proximity to their advantage. Several types of border regions can be identified in transition countries. Two groups of them seem to be worth analysing: internal border regions, i.e. those locating along the border with a present or candidate member to the EU, and external border regions, i.e. regions located at the borders of the "enlarged EU".
Modeling Upper Layer Reaction to QoS Degradation as a Congestion Avoidance Mechanism

SUMMARY On the Internet, end hosts and network nodes interdependently work to smoothly transfer traﬃc. Observed traﬃc dynamics are the result of those interactions among those entities. To manage Internet traﬃc to provide satisfactory quality services, such dynamics need to be well understood to predict traﬃc patterns. In particular, some nodes have a function that sends back-pressure signals to backward nodes to reduce their sending rate and mitigate congestion. Transmission Control Protocol (TCP) congestion control in end-hosts also mitigates traf-(cid:12)c deviation to eliminate temporary congestion by reducing the TCP sending rate. How these congestion controls mitigate congestion has been extensively investigated. However, these controls only throttle their sending rate but do not reduce traﬃc volume. Such congestion control fails if congestion is persistent, e.g., for hours, because unsent traﬃc demand will in(cid:12)nitely accumulate. However, on the actual Internet, even with persistent congestion, such accumulation does not seem to occur. During congestion, users and/or applications tend to reduce their traﬃc demand in reaction to quality of service (QoS) degradation to avoid negative service experience. We previously estimated that 2% packet loss results in 23% traﬃc reduction because of this upper-layer reaction [1]. We view this reduction as an upper-layer congestion-avoidance mechanism and construct a closed-loop model of this mechanism, which we call the Upper-Layer Closed-Loop (ULCL) model. We also show that by using ULCL, we can predict the degree of QoS degradation and traﬃc reduction as an equilibrium of the feedback loop. We applied our model to traﬃc and packet-loss ratio time series data gathered in an actual network and demonstrate that it eﬀectively estimates actual traﬃc and packet-loss ratio.
Performance of organic leafy vegetables production under Hyderabad conditions

Leaf yields of amaranthus and palak varied significantly due to application of different organic manures and inorganic fertilizers. Application of recommended dose of fertilizers registered higher yield in first cut but in subsequent cuts and overall total yield with application of FYM @ 20 t ha -1 in combination with biofertilizers, PSB + Azospirillum each @ 5 kg ha -1 recorded significantly higher yield in both the crops. The B:C ratio in both the crops was high with application of recommended fertilizer dose compared to organics. The quality of fresh leaf yield was good with significantly lower oxalate content in organic production in both amaranthus and palak. Production of consumables through organic cultivation tastes better and contains a better balance of vitamins and minerals than conventionally grown food. Leafy vegetables place a vital role in daily diet of humans with high nutritional values. Leafy vegetables are rich source of vitamins, minerals and dietary fibre content . Leafy vegetables contribute 80-100 g per day per person in daily diet wich was 40% of the daily total vegetable consumption per day per person as, leaf vegetables are short duration and remunerative farmers use huge amount of nitrogenous fertilizers for quick and luxurious growth which leads to poor quality and also ends up in ground waters contamination. If these greens are cultivated totally with high dose of chemical fertilizers, growth and yields are high but quality of the greens will be reduced drastically. Growing of leafy vegetables in organic conditions not only improves the quality but also extends the shelf life. The increased use of organic inputs in the production of agricultural and horticultural crops is being helpful not only for human health but also for plant and soil health.
Modern noninvasive methods for monitoring glucose levels in patients: a review

Abstract This paper presents the current state of the art of noninvasive glucose monitoring. In recent years, we can observe constant increase in the incidence of diabetes. About 40% of all performed blood tests apply to the glucose tests. Formerly, this lifestyle disease occurred mainly in rich countries, but now it is becoming more common in poorer countries. It is related to the increase in life expectancy, unhealthy diet, lack of exercise, and other factors. Untreated diabetes may cause many complications or even death. For this reason, daily control of glucose levels in people with this disorder is very important. Measurements with a traditional glucometer are connected with performing finger punctures several times a day, which is painful and uncomfortable for patients. Therefore, researches on other methods are ongoing. A method that would be fast, noninvasive and cheap could also enable testing the state of the entire population, which is necessary because of the number of people currently living with undiagnosed type 2 diabetes. Although the first glucometer was made in 1966, the first studies on glucose level measurement in tear film were documented as early as 1937. This shows how much a noninvasive method of diabetes control is needed. Since then, there have been more and more studies on alternative methods of glucose measurement, not only from tear fluid, but also from saliva, sweat, or transdermally.
Dysregulation of Complement Activation and Placental Dysfunction: A Potential Target to Treat Preeclampsia?

Preeclampsia is one of the leading causes of maternal and neonatal mortality and morbidity worldwide, affecting 2–8% of all pregnancies. Studies suggest a link between complement activation and preeclampsia. The complement system plays an essential role in the innate immunity, leading to opsonization, inflammation, and elimination of potential pathogens. The complement system also provides a link between innate and adaptive immunity and clearance of immune complexes and apoptotic cells. During pregnancy there is increased activity of the complement system systemically. However, locally at the placenta, complement inhibition is crucial for the maintenance of a normal pregnancy. Inappropriate or excessive activation of the complement system at the placenta is likely involved in placental dysfunction, and is in turn associated with pregnancy complications like preeclampsia. Therefore, modulation of the complement system could be a potential therapeutic target to prevent pregnancy complications such as preeclampsia. This review, based on a systematic literature search, gives an overview of the complement system and its activation locally in the placenta and systemically during healthy pregnancies and during complicated pregnancies, with a focus on preeclampsia. Furthermore, this review describes results of animal and human studies with a focus on the complement system in pregnancy, and the role of the complement system in placental dysfunction. Various clinical and animal studies provide evidence that dysregulation of the complement system is associated with placental dysfunction and therefore with preeclampsia. Several drugs are used for prevention and treatment of preeclampsia in humans and animal models, and some of these drugs work through complement modulation. Therefore, this review further discusses these studies examining pharmaceutical interventions as treatment for preeclampsia. These observations will help direct research to generate new target options for prevention and treatment of preeclampsia, which include direct and indirect modulation of the complement system.
The Immuno-Modulatory Effects of Inhibitor of Apoptosis Protein Antagonists in Cancer Immunotherapy

One of the hallmarks of cancer cells is their ability to evade cell death via apoptosis. The inhibitor of apoptosis proteins (IAPs) are a family of proteins that act to promote cell survival. For this reason, upregulation of IAPs is associated with a number of cancer types as a mechanism of resistance to cell death and chemotherapy. As such, IAPs are considered a promising therapeutic target for cancer treatment, based on the role of IAPs in resistance to apoptosis, tumour progression and poor patient prognosis. The mitochondrial protein smac (second mitochondrial activator of caspases), is an endogenous inhibitor of IAPs, and several small molecule mimetics of smac (smac-mimetics) have been developed in order to antagonise IAPs in cancer cells and restore sensitivity to apoptotic stimuli. However, recent studies have revealed that smac-mimetics have broader effects than was first attributed. It is now understood that they are key regulators of innate immune signalling and have wide reaching immuno-modulatory properties. As such, they are ideal candidates for immunotherapy combinations. Pre-clinically, successful combination therapies incorporating smac-mimetics and oncolytic viruses, as with chimeric antigen receptor (CAR) T cell therapy, have been reported, and clinical trials incorporating smac-mimetics and immune checkpoint blockade are ongoing. Here, the potential of IAP antagonism to enhance immunotherapy strategies for the treatment of cancer will be discussed.

The grass-dwelling arthropod communities of the coastal reserve "Randu pavas" in Latvia

Melecis V. , Karpa A. , Spu��is V. 1998. The grass-dwelling arthropod communities of the coastal reserve "Randu pavas" in Latvia. - Latv. Entomol. , 36: 55-65. In 1994, the grass-dwelling arthropods of the littoral meadows of the coastal reserve Randu meadows ("Randu pavas") in Latvia were investigated. Arthropods were collected by entomological sweep net within 7 types of habitats with different moisture regime. Diptera dominated among the insects and was represented by 40 families. Low numbers of other groups (Coleoptera, Heteroptera, and Auchenorrhyncha) commonly abundant within inland meadows were explained by specific ecological conditions of the seashore meadows. Numbers of most of arthropod groups and characteristics of community structure (number of families, Shannon's diversity index H', equitability index E and Margarlef's index IM) had unimodal distributions on a moisture gradient.
Highly efficient distributed hypergraph analysis: real-time partitioning and quantized learning

Hypergraphs have been shown to be highly effective when modeling a wide range of applications where high-order relationships are of interest, such as social network analysis and object classification via hypergraph embedding. Applying deep learning techniques on large scale hypergraphs is challenging due to the size and complex structure of hypergraphs. This thesis addresses two problems of hypergraph analysis, real-time partitioning and quantized neural networks training, in a distributed computing environment. When processing a large scale hypergraph in real-time and in a distributed fashion, the quality of hypergraph partitioning has a significant influence on communication overhead and workload balance among the machines participating in the distributed processing. The main challenge of real-time hypergraph partitioning is that hypergraphs are represented as a dynamic hypergraph stream formed by a sequence of hyperedge insertions and deletions, where the structure of a hypergraph is constantly changing. The existing methods that require all information of a hypergraph are inapplicable in this case as only a sub-graph is available to the algorithm at a time. We solve this problem by proposing a streaming refinement partitioning (SRP) algorithm that partitions a real-time hypergraph flow in two phases. With extensive experiments on a scalable hypergraph framework named HyperX, we show that SRP can yield partitions that are of the same quality as that achieved by offline partitioning algorithms in terms of communication overhead and workload balance. For machine learning tasks over hypergraphs, studies have shown that using deep neural networks (DNNs) can improve the learning outcomes. This is because the learning objectives in hypergraph analysis are becoming more complex these days, where features are difficult to define and are highly-correlated. DNNs can be used as a powerful classifier to construct features automatically. However, DNNs require high computational power and network bandwidth as the size of
