Anaplasmosis in ruminants and infesting ticks vectors settling Egyptian desert : Epidemiological updates regarding genetic profiles

Anaplasmosis are notifiable diseases globally distributed infection due to its socioeconomic impact and the restrictions induced on life animal trading. The infection is characterized by the so called geographical isolate with zoonotic potentials. The aim of this study was determining the incidence of anaplasmosis in animal hosts with regards to geo-biotypes distribution and ixodid ticks preference in transmission into three ruminants’ hosts settling 12 localities in desert provinces in Egypt. A total of 5223 adult ixodid ticks were collected from 270 ruminants; 110 camels, 120 sheep, and 40 cattle, examined seasonally from June 2014 to July 2016. The statistical analysis of infestation density of all species on each hosts was highly significant. Nucleotides similarities of ticks’ 18S rDNA and 16S rDNA markers were 99-100% against Genbank records, which confirmed ticks identification by morphological key in to 4 genera: Ambylomma, Hyalomma, Boophilus, and Rhipicephalus including 14 species. Molecular screening for anaplasmosis was carried out by multi-genes sequencing technology; where 16S rDNA was the primary target. The overall Anaplasmataceae infections incidence in animals hosts and their infesting ticks’ spp. were 3.753% and 47.77%, respectively. Positive PCRs were then typed into species level by three pairs of primers complementary to stretches in major surface protein 4 (msp4) and heat shock protein 60kDa (hsp60). The identities of both genes to other recorded in Genbank ranged 95100%. The incidence of the 7 detected Anaplasma spp. in ticks recorded 36.22%, 21.94%, 11.22%, 10.72%, 7.65%, 6.63% and 5.62% by A. phagocytophilum, unclassified spp. , A. ovis, A. marginale, A. plates, A. bovis, and A. central, respectively. Whereas, incidence in positive animal hosts recorded 33.33%, 29.45%, 12.40%, and 8.53%, for the unclassified spp. , A. phagocytophilum, A. marginale, and A. ovis, respectively. While equal incidence recorded 5.43% was reported for A. plates, A. bovis, and A. central, respectively. Camels were found infected with all detected spp. While cattle sheep were infected except with A. ovis & A. plates in cattle, as well as, A. bovis & A. central in sheep. B. annulatus and H. dromedarii were found carriers for all detected Anaplasma spp. H. m. rufipes, on the other hand, was positive for A. phagocytophilum, A. ovis and A. plates only. The present study is the first to declare positive specimens with A. ovis, A. marginale, A. plates, and A. central not which confirmed the endemic status of anaplasmosis. Co-infections with more than one species presented alarm for possible future epidemics by new species not clearly classified which necessitate more research and should no longer be neglected.
Escape Path Obstacle-Based Mobility Model (EPOM) for Campus Delay-Tolerant Network

In Delay-Tolerant Networks (DTNs), humans are the main carriers of mobile devices, signifying that human mobility can be exploited by extracting nodes’ interests, social behavior, and spatiotemporal features for the performance evaluation of DTNs protocols. This paper presents a new mobility model that describes students’ daily activities in a campus environment. Unlike the conventional random walk models, which use a free space environment, our model includes a collision-avoidance technique that generates an escape path upon encountering obstacles of different shapes and sizes that obstruct pedestrian movement. We evaluate the model’s usefulness by comparing the distributions of its synthetic traces with realistic traces in terms of spatial, temporal, and connectivity features of human mobility. Similarly, we analyze the concept of dynamic movement clusters observed on the location-based trajectories of the studied real traces. The model synthetically generates traces with the distribution of the intercluster travel distance, intracluster travel distance, direction of movement, contact duration, intercontact time, and pause time similar to the distribution of real traces.
N T ] 1 2 A pr 2 01 8 ON CLASS GROUPS OF RANDOM NUMBER FIELDS

The aim of the present paper is to add, in several ways, to our understanding of the Cohen–Lenstra–Martinet heuristics on class groups of random number fields. Firstly, we point out several difficulties with the original formulation, and offer possible corrections. Secondly, we recast the heuristics in terms of Arakelov class groups of number fields. Thirdly, we propose a rigorously formulated Cohen–Lenstra–Martinet conjecture.
Use of Ultrasonography to Discriminate Psoriatic Arthritis from Fibromyalgia: A Post-Hoc Analysis of the ULISSE Study

In psoriatic arthritis (PsA) patients with concomitant chronic widespread pain, the differential diagnosis with fibromyalgia syndrome (FMS) can be challenging. We evaluated whether ultrasound (US) examination of entheseal sites can distinguish pain from (PsA) enthesitis versus FMS. PsA and FMS patients underwent clinical evaluation and gray-scale (GS; B-mode) and power Doppler (PD) US examination of the entheses. At least one enthesis with GS- and PD-mode changes was found in 90% and 59.3% of PsA patients (n = 140) and 62.7% and 35.3% of FMS patients (n = 51), respectively. GS and PD identified changes in 49.5% and 19.2% of the 840 PsA entheses and 22.5% and 7.9% of the 306 FMS entheses, respectively. Receiver operating characteristic curve analysis showed an area under the curve of 0.77 and 0.66 for B- and PD-mode, respectively, 3.5 being the best cut-off GS-score to discriminate the two conditions. Multivariate regression showed that Achilles and proximal patellar tendon enthesitis (B-mode) were strongly associated with PsA (odds ratio, ~2). Principal component analysis (B-mode) confirmed that PsA patients have a higher number of involved entheses and patterns of entheseal involvement than FMS patients. US evaluation of the entheses may help differentiate chronic widespread pain from PsA versus FMS.
The Verb-Particle Alternation in the Scandinavian Languages

The Germanic languages employ a set of prepositional particles to indicate direction or location, and in an extended sense to indicate results or end-states of various kinds of events. These particles appear in a large number of idiomatic combinations with verbs, but despite the vast number of combinations, certain regularities of meaning are observed. I argue that this has to do with facts about the argument structure of verbs and prepositions, facts which can be characterized as constraints on possible lexical entries, or as limitations of the language of conceptual structure on which lexical entries are based. The verb-particle construction shows characteristic syntactic properties, with interesting variation across the Scandinavian languages. I show how a small clause analysis, where the particle is the predicate of a small clause complement to the verb, can be employed to account for the various properties observed, including the surface order of the particle and what is traditionally taken to be the direct object of the verb, and incoporporation of the particle in certain passive constructions. I argue that these constructions provide evidence for a more articulated structure for the small clause, following Kaynes analysis of participial constructions. I show several parallels between main clauses and these embedded clausal structures, including facts having to with the location of subjects, the EPP, and agreement.
Non-Invasive Prenatal Detecting of Achondroplasia In Earlier Stage of Pregnancy By Droplet-Digital PCR

Background: Achondroplasia (ACH) is generally detected by abnormal prenatal ultrasound findings in the late stage of pregnancy and then confirmed by molecular genetic testing of fetal genomic DNA obtained invasively. Most ACH cases appear to be de novo mutations with FGFR3 gene, so it is a challenge to screen ACH fetus out in the early stage of pregnancy.Objective: The aim of this study was to validate the possibility of detect fetus ACH along with non-invasive prenatal screening(NIPS) routinely in the early stage of pregnancy.Methods: 5927 cases of pregnant women undergoing NIPS were enrolled in this study. An additional 5ml of blood was collected together with NIPS blood sampling. Cell free DNA was extracted for the detecting of fetus ACH. Droplet-digital PCR(ddPCR) method based on the amplification of the two possible mutant alleles (c. 1138G>A and c. 1138G>C) of FGFR3 gene was performed to screen fetus ACH. Prenatal ultrasound and amniocentesis were then performed to confirm the positive screening result of ACH cases. The mutation sites of fetus were identified via Sanger sequencing by using amniotic fluid cells. For the screen negative cases of pregnant women, we followed up the results of prenatal diagnosis or the general conditions of the newborns.Results: One pregnant woman with fetus ACH were screened out at 22 weeks by Non-invasive prenatal detecting. Later prenatal ultrasound confirmed fetal skeletal dysplasia. Sanger sequencing confirmed de novo FGFR3 1138G>A mutant of the fetus. No ACH fetus or newborns were found in the rest detected negative cases of enrolled pregnant women.Conclusion: ddPCR technology could effectively identify de novo mutation like ACH of fetus noninvasively. We prospect the clinical application of ddPCR can expand the range of prenatal screen in the future.
Toda hierarchies and their applications

The 2D Toda hierarchy occupies a central position in the family of integrable hierarchies of the Toda type. The 1D Toda hierarchy and the Ablowitz–Ladik (aka relativistic Toda) hierarchy can be derived from the 2D Toda hierarchy as reductions. These integrable hierarchies have been applied to various problems of mathematics and mathematical physics since 1990s. A recent example is a series of studies on models of statistical mechanics called the melting crystal model. This research has revealed that the aforementioned two reductions of the 2D Toda hierarchy underlie two different melting crystal models. Technical clues are a fermionic realization of the quantum torus algebra, special algebraic relations therein called shift symmetries, and a matrix factorization problem. The two melting crystal models thus exhibit remarkable similarity with the Hermitian and unitary matrix models for which the two reductions of the 2D Toda hierarchy play the role of fundamental integrable structures.
Rainfall trends in the Niger-South Basin, Nigeria, 1948-2008

Understanding rainfall trend can be a first step in the planning and management of water resources especially at the basin scale. In this study, standard tests are used to examine rainfall trends based on monthly, seasonal and mean annual series at the Niger-South Basin, Nigeria, between 1948 and 2008. Rainfall variability index showed that the decade 2000s was the driest (-2.1), while 1950s was the wettest (+0.8), with the decade 1980s being the driest in the second half of the last century, whereas the year 1983 was the driest throughout the series. Over the entire basin, rainfall variability was generally low, but higher intra-monthly than inter-annually. Annual rainfall was dominated by August, contributing about 15%, while December contributed the least (0.7%). On a seasonal scale, July-August-September (JJA) contributed over 40% of the annual rainfall, while rainfall was lowest during December-January- February (DJF) (4.5%). The entire basin displayed negative trends but only 15% indicated significant changes (a<0.1), while the magnitudes of change varied between -3.75 and -0.25 mm/yr. Similarly, only JJA exhibited insignificant upward trend, while the rest showed negative trends. About eight months of the year showed reducing trends, but only January trend was significant. Annual downward trend was generally observed in the series. The trend during 1948-1977 was negative, but it was positive for the 1978-2008 period. Hence, water resources management planning may require construction of water storage facilities to reduce summer flooding and prevent possible future water scarcity in the basin.
Binary quartic forms having bounded invariants, and the boundedness of the average rank of elliptic curves

We prove a theorem giving the asymptotic number of binary quartic forms having bounded invariants; this extends, to the quartic case, the classical results of Gauss and Davenport in the quadratic and cubic cases, respectively. Our techniques are quite general, and may be applied to counting integral orbits in other representations of algebraic groups. We use these counting results to prove that the average rank of elliptic curves over $\mathbb{Q}$, when ordered by their heights, is bounded. In particular, we show that when elliptic curves are ordered by height, the mean size of the 2-Selmer group is 3. This implies that the limsup of the average rank of elliptic curves is at most 1.5.
On the direction of remanent magnetization of the quartz porphyry dikes in SE Finland

NEUVONEN, K. J., 1986: On the direction of remanent magnetization of the quartz porphyry dikes in SE Finland. Bull. Geol. Soc. Finland 58, Part 1, 195—201. Attempts are made to determine the direction of remanent magnetization of the rapakivi varieties belonging to the Wiborg (Viipuri) rapakivi massif and its satellites in the precambrian Baltic Shield. Hard and stable remanence was found only in the quartz porphyry dikes which are closely associated with the rapakivi granites and have a radiometric U-Pb age about 1630 Ma. The magnetization found evidently represents the direction of the geomagnetic field prevailing during the late phase of the evolution of the rapakivi magma. The calculated paleomagnetic pole site (30° N, 175° E with »normal» polarity) agrees well with those previously reported for rocks of about the same age in the Baltic Shield.
Transmission line model for the near‐instantaneous transmission of the ionospheric electric field and currents to the equator

The simultaneous onset of the preliminary impulse (PI) of the geomagnetic sudden commencement at high latitude and dayside dip equator is explained by means of the TM0 mode waves propagating at the speed of light in the Earth‐ionosphere waveguide (EIW) [Kikuchi et al., 1978]. A couple of issues remain to be addressed in the EIW model: (1) How is the TM0 mode wave excited by the field‐aligned currents (FACs) in the polar region? (2) How are the quasi‐steady ionospheric currents achieved by the TM0 mode waves? (3) How simultaneous or delayed are the onset and peak of the equatorial PI with respect to the high‐latitude PI? To address these issues, we examine the TEM (TM0) mode wave propagation in the finite‐length transmission lines replacing the pair of FACs (magnetosphere‐ionosphere (MI) transmission line) and the Earth‐ionosphere waveguide (ionosphere‐ground (IG) transmission line). The issue (1) is addressed by showing that a fraction of the TEM mode wave is transmitted from the MI to IG transmission lines through the polar ionosphere. To address the issues (2) and (3), we examine the properties of the finite‐length IG transmission line with finite ionospheric conductivity. It is shown that the ionospheric currents start to grow instantaneously and continue to grow gradually with time constants of 1–10 s depending on the ionospheric conductivity. The MIG transmission line enables us to explain the instantaneous onset and delayed peak time of the equatorial PI and quick electric field response of the low‐latitude ionosphere and inner magnetosphere.
New Energy Corridors in the Euro-Mediterranean Area: The Pivotal Role of Sicily

The present paper deals with the new opportunities deriving from the interconnections of the European and North African transmission systems. In order to achieve a single international market for electricity exchanges, interconnections between networks in different countries are becoming increasingly important and Sicily, for its geographical position in the middle of the Mediterranean Sea, will undoubtedly play an important role as an electrical bridge between Europe and the North Africa in the near future. The paper, presenting the actual electro-energetic context of Tunisia, reports the new important interconnection already realized in South Italy (in particular in Sicily) and describe the planned interventions of the near future. In the second part of the paper, using the Neplan software package (10.7.4, NEPLAN AG, CH-8700 Kusnacht (ZH), Switzerland) for simulating the grid, some load flows are carried out to check some operating scenarios (2020 and 2025) considering energy flows from north to south, avoiding system violations.
Fecal Dand L-Lactate , Succinate , and Volatile Fatty Acid Levels in Young Dairy Calves

For evaluation of physiologically significant organic anions in the colonic environment, 87 samples of normal feces were collected from the rectum of 15 calves less than 60 days old. The calves were fed milk replacer with free access to starter diet and hay. After fecal extraction with water, pH, Dand L-lactate, succinate, and volatile fatty acid (VFA) concentrations were determined. There was wide variation in fecal pH (4.3 to 7.7). Higher lactate concentrations were observed in feces samples with lower pH, and most of these samples were collected during the first 4 weeks of life. Elevated lactate concentrations included both the Dand L-isomers, and the D-isomer comprised approximately 30–50% of total lactate. Elevated succinate concentrations were observed in only 8 fecal samples, while other samples had lower or trace amounts of succinate. Elevated fecal succinate showed no relationship with fecal pH or VFA concentrations. Fecal VFA concentrations were lower in samples collected in the early postnatal stage, but fecal VFA concentrations were not necessarily related to age. We confirmed that fecal Dand L-lactate concentrations increased with a concomitant decrease of VFA in the acidic lumen of the colon, although acidic feces were not necessarily accompanied by elevated concentrations of lactate. In contrast, succinate production was not related to fecal pH or VFA concentrations.

Workforce capacity planning with hierarchical skills, long-term training, and random resignations

This paper addresses a multistage capacity planning problem for a hierarchically skilled workforce in a production environment. Recruits are hired with little or no experience and are trained over multiple periods to perform jobs that require increasing levels of skill. Training can take place either off-the-job, on-the-job or a combination thereof. The problem is complicated by random resignations that can lead to labor shortfalls that jeopardise continuous operations. The objective is to balance workforce costs with penalty costs associated with skill shortages. The problem is modelled as a Markov decision process for which several parameterised decision rules are proposed to find solutions. A large-scale neighbourhood search is developed to deal with ‘noisy’ cost function measurements. Experiments show that good parameter values can be found in less than four hours using real-world data. When training requires extensive supervision, the results indicate that the number of workers concurrently in training should be limited. They also show that a shorter, intense training period during which employees do not perform regular tasks is generally preferable to a longer training period where employees spend time both on and off the job. Finally, we demonstrate the value of worker flexibility when downgrading is applied.
Capital Ownership And Its Impact On International Trade And Economic Growth: The Tunisian Experience

Despite the widespread belief that a privatized economy performs better than a centrally planned one, there is no empirical evidence on whether changing the structure of capital ownership affects trade and growth in developing countries. This paper addresses this issue by analyzing and comparing the distinctive effects of privately and publicly owned capital on international trade and economic growth. Based on a modified version of the neo-classical one-sector aggregate production technology, we investigate the intertemporal interactions among the growth rate of real output, private capital, public capital, international trade and labor. The results of applying our methodology to data from Tunisia suggest that private capital performs better than public capital in promoting economic growth and international trade.
