Flash Crowd Effect in RCP

— The Rate Control Protocol (RCP) [1] is an explicit congestion control mechanism that, amongst other characteristics, reduces the average ﬂow completion time (AFCT) metric by one order of magnitude when compared to TCP NewReno. RCP reduces the AFCT by allowing new ﬂows to instantly use the same rate as existing ﬂows in the network. This results in link utilization temporarily exceeding available capacity when ﬂows enter a network, inducing queue build-up. As such, RCP is particularly vulnerable to ﬂash crowds , whereby a system witnesses a signiﬁcant increase in the number of ﬂows over a short period of time. In this paper we analyze RCP’s response to varying rates of increase in the number of ﬂows. We conclude that, for a given arrival growth rate, RCP is able to stabilize queue length as long as this rate does not exceed well deﬁned limits. We quantify the queue length required to stabilize the system response and the limit arrival growth rate using a model of RCP that incorporates the effect of new ﬂow arrivals. Finally, we validate our analysis through ns-2 simulations.
A Mediterranean medicinal plant in the continental Balkans: A plastid DNA-based phylogeographic survey of Salvia officinalis (Lamiaceae) and its conservation implications

Abstract Stojanović D. , Aleksić J. M. , Jančić I. & Jančić R. : A Mediterranean medicinal plant in the continental Balkans: A plastid DNA-based phylogeographic survey of Salvia officinalis (Lamiaceae) and its conservation implications. — Willdenowia 45: 103–118. 2015. — Version of record first published online on 20 March 2015 ahead of inclusion in April 2015 issue; ISSN 1868-6397; © 2015 BGBM Berlin-Dahlem. DOI: http://dx.doi. org/10.3372/wi.45. 45112 Salvia officinalis (Lamiaceae), common or Dalmatian sage, is a Mediterranean aromatic and medicinal plant used in medicine since ancient times. Knowledge on current genetic patterns and genealogical history of its natural populations is required for both breeding efforts and species conservation. We used sequences of two chloroplast intergenic spacers, 3′rps16—5′trnK and rpl32—trnL, from 83 individuals from eight natural populations to distinguish between anthropogenic vs natural origin of four disjunct inland populations found outside of the main Adriatic range of the species. We found seven haplotypes, high total gene diversity (HT = 0.695) and genetic differentiation (GST = 0.682), as well as a phylogeographic structure with two lineages, a sub-structured inland-Adriatic lineage (IAL, comprising inland and Adriatic sub-lineages) and a purely Adriatic lineage (PAL). All four inland and disjunct populations, which comprised the inland sub-lineage of IAL, were almost fixed for a distinct haplotype genealogically closely related to the ancestral haplotype and displayed other features of relict populations. Along with previous biogeographic data and other lines of evidence, assumptions on their anthropogenic origin were rejected. At present, a less diverse IAL (Hd = 0.426, &pgr; = 0.00106) and a more diverse PAL (Hd = 0.403, &pgr; = 0.00257), whose divergence was dated to the Pliocene (3.267 Mya), do not exhibit signs of recent demographic expansions and overlap on the SE Adriatic coast, a region delineated as the main glacial refugium of S. officinalis. Conservation measures accounting for the historical distinctiveness of populations and focusing on currently the most threatened populations are recommended.

Enhanced isoproturon mineralisation in a clay silt loam agricultural soil

14C-ring-labelled isoproturon mineralisation was investigated in a French agricultural soil previously exposed to isoproturon. 50 different soil samples collected every 2 m along a transect of 100 m in length were treated one or two times with isoproturon under laboratory conditions and analysed by radiorespirometry. 94% of the soil samples showed a high ability to mineralise isoproturon with a relatively low variability in the cumulative percentage of mineralisation ranging from 30 to 51% of the initially added radioactivity for the samples treated once with the herbicide. About 45 to 67% of the initially added radioactivity was transformed into 4 CO 2 in soil samples treated twice with isoproturon. Fifty-one to 30% of the radioactive pesticide formed bound residues 120 days after the first isoproturon treatment. The radioactive compound incorporated in the microbial biomass ranged from 3 to 4% of the initially added radioactivity. The methanol-extractable radioactivity was negligible and in the majority of soil samples no metabolites could be detected by high performance liquid chromatography analyses. However, in one soil sample showing low ability to mineralise isoproturon, the mono-demethyl isoproturon derivative represented about 12% of the methanol-extractable fraction. After the second isoproturon treatment, the rate of isoproturon mineralisation was enhanced in most soil samples and the number of soil samples showing a low isoproturon mineralisation capacity decreased. A significant relationship (correlation coefficient, 0.89) between the logarithm of the mineralisation rate (In k) and the soil pH was found, with a particularly strong positive effect on isoproturon mineralisation for pH > 6.5.
DISCOVER COMPATIBILITY: MACHINE LEARNING WAY

To live in harmony, it is advisable to have awareness of matching among various individual behaviors. Naïve Bays algorithm with extensions is executed on Zodiac Signs and Name Style datasets to develop a research system. This system is implemented to understand how compatible an individual is based on not only zodiac signs but numerology also. Numerology is a science which suggests different naming style, with unique spelling of person. Every spelling is supported with special set of characteristics. These naming style characteristics are matched with zodiac signs to find similarity index values, which gives compatibility about various relations including family, professional and friend.
Anesthetic management of transcatheter aortic valve implantation

Transcatheter aortic valve implantation (TAVI) is an emergent technique for high-risk patients with aortic stenosis. TAVI poses significant challenges about its management because of the procedure itself and the population who undergo the implantation. Two devices are currently available and marketed in Europe and several other technologies are being developed. The retrograde transfemoral approach is the most popular procedure; nevertheless, it may not be feasible in patients with significant aortic or ileo-femoral arterial disease. Alternatives include a transaxillary approach, transapical approach, open surgical access to the retroperitoneal iliac artery and the ascending aorta. A complementary approach using both devices and alternative routes tailored to the anatomy and the comorbidities of the single patient is a main component for the successful implementation of a TAVI program. Anesthetic strategies vary in different centers. Local anesthesia or general anesthesia are both valid alternatives and can be applied according to the patient’s characteristics and procedural instances. General anesthesia offers many advantages, mainly regarding the possibility of an early diagnosis and treatment of possible complications through the use of transesophageal echocardiography. However, after the initial experiences, many groups began to employ, routinely, sedation plus local anesthesia for TAVI, and their procedural and periprocedural success demonstrates that it is feasible. TAVI is burdened with potential important complications: vascular injuries, arrhythmias, renal impairment, neurological complications, cardiac tamponade, prosthesis malpositioning and embolization and left main coronary artery occlusion. The aim of this work is to review the anesthetic management of TAVI based on the available literature.
Codifference can detect ergodicity breaking and non-Gaussianity

We show that the codifference is a useful tool in studying the ergodicity breaking and non-Gaussianity properties of stochastic time series.While the codifference is ameasure of dependence that was previously studiedmainly in the context of stable processes, we here extend its range of applicability to random-parameter and diffusing-diffusivitymodels which are important in contemporary physics, biology andfinancial engineering.We prove that the codifference detects forms of dependence and ergodicity breakingwhich are not visible from analysing the covariance and correlation functions.We also discuss a relatedmeasure of dispersion, which is a nonlinear analogue of themean squared displacement.
role2vec: Role-based Network Embeddings

Random walks are at the heart of many existing network embedding methods. However, such methods have many limitations that arise from the use of traditional random walks, e.g. , the embed-dings resulting from these methods primarily capture proximity (communities) among the vertices as opposed to structural equivalence/similarity (roles). In this work, we introduce the Role2Vec framework which uses the flexible notion of attributed random walks , and serves as a basis for generalizing existing methods such as DeepWalk, node2vec, and many others that leverage random walks. Our proposed framework enables these methods to be more widely applicable by learning functions that capture the behavioral roles of the nodes. We show that our proposed framework is effective with an average AUC improvement of 16 . 55% while requiring on average 853x less space than existing methods.
Rules and mechanism for the oxidation of lignin-based aromatic aldehyde under alkaline wet oxygen

To explore the extensive oxidative mechanism of syringaldehyde, vanillin, and p-hydroxybenzaldehyde during the alkaline wet oxidation process (AWOP), the yield of these aromatic aldehydes from AWOP at various temperatures and reaction times was studied. The results showed that the aromatic aldehydes could not be converted into the corresponding aromatic acids during the AWOP, and that the aromatic aldehyde was stable when subjected to the oxygen-free AWOP. However, as the reaction temperature increased or the number of methoxyl groups on the aromatic ring increased, the yield of aromatic aldehyde sharply decreased during the AWOP. The reason for the decreased yield was that the aromatic aldehyde underwent ring-opening reactions. The possible mechanism of the degradation indicated that the number of methoxyl groups on the phenolic ring determined the stability of the key intermediate of this reaction. The conversion of isoeugenol to vanillin during the AWOP at 60 ºC was > 99%, and the vanillin yield and selectivity were both 69.8%, indicating that the decrease in yield of the product from this degradation of lignin substrate and the product can be reduced or avoided in the AWOP at suitable temperature.
Carnes PSE (Pale, Soft, Exudative) e DFD (Dark, Firm, Dry) em lombo suíno numa linha de abate industrial

The needs of higher production of low fat pork have conducted changes on the muscle biochemical characteristics leading to color abnormality producing so-called PSE and DFD meats. The consequence is a relevant economical loss due to the impairment of meat functional properties. In this experiment, 946 samples of Longissimus dorsi m. from barrows and gilts of Dalland lineage, of 100 days of age, were evaluated in a pork abattoir located in the south of Brazil. Samples were classified based on the L*24 h e pH24 h values. Results showed the occurrence of 22.8% of PSE meat, 1.0% de DFD meat and 76.2% of normal meat. These relatively higher values for PSE show undoubtedly the needs to carry out pre- and post-mortem management in order to maintain meat quality thus avoiding the excessive economic cost due to these meat abnormalities.
A new method for the culture of marine sponges and its application for experimental studies

Abstract To date only few ecophysiological studies with marine sponges have been reponed because of difficulties in keeping these animals in the laboratory. In this paper, a new approach to successful longterm maintenance will be presented. When dean pieces of freshly collected Halichondria panicea without any algal or other remnants were mounted on glass slides or suspended from nylon threads, they attached to the anificial substrates within one week. Longlasting survival was highest (nearly 100%) with the suspended material. After feeding with suspensions of Chlorella sp. , growth could be measured; growth preferably took place along the substrates (on slides extending in a flat encrustation, on nylon threads preferably in an unidirectional manner. These artificially multiplied sponges could be used for comparative srudies of the physiological potential of the species. North Sea specimens possessed higher metabolic rates at the experimental temperatures of 10 and 15°C in comparison with those from the Ba.
A Dynamic Structural Model of Virus Diffusion and Network Production: A First Report

This paper presents a dynamic structural model to evaluate economic and public health effects of the diffusion of COVID-19, as well as the impact of factual and counterfactual public policies. Our framework combines a SIR epidemiological model of virus diffusion with a structural game of network production and social interactions. The economy comprises three types of geographic locations: homes, workplaces, and consumption places. Each individual has her own set of locations where she develops her life. The combination of these sets for all the individuals determines the economy's production and social network. Every day, individuals choose to work and consume either outside (with physical interaction with other people) or remotely (from home, without physical interactions). Working (and consuming) outside is more productive and generates stronger complementarities (positive externality). However, in the presence of a virus, working outside facilitates infection and the diffusion of the virus (negative externality). Individuals are forward-looking. We characterize an equilibrium of the dynamic network game and present an algorithm for its computation. We describe the estimation of the parameters of the model combining several sources of data on COVID-19 in Ontario, Canada: daily epidemiological data; hourly electricity consumption data; and daily cell phone data on individuals' mobility. We use the model to evaluate the health and economic impact of several counterfactual public policies: subsidies for working at home; testing policies; herd immunity; and changes in the network structure. These policies generate substantial differences in the propagation of the virus and its economic impact.
River regulation and fish communities in the Murray-Darling River system, Australia

Fish communities from four catchments in the Murray—Darling river system were analysed in relation to climate, hydrology and river regulation. Using the annual proportional flow deviation as a measure of river regulation, the Paroo River catchment was assessed as unregulated, the Darling River catchment as mildly regulated and the Murrumbidgee River and River Murray catchments as highly regulated. A total of 11010 fish, representing nine native and three alien species, was caught during high and low flow seasons in the four catchments. Native species, such as golden perch Macquaria ambigua (Percichthyidae), bony herring Nematalosa erebi (Clupeidae) and spangled perch Leiopotherapon unicolor (Teraponidae), dominated fish communities in the Paroo and Darling catchments, but alien species, mostly carp, Cyprinus carpio (Cyprinidae), were also abundant. Both native and alien species were more abundant in these catchments after flooding, but there was little change in species composition between high and low flow seasons at the catchment level. Carp dominated communities in the Murray and Murrumbidgee catchments. There was a significant trend for reduced species diversity in increasingly regulated catchments. River regulation may alter the relative abundance of native and alien fish by desynchronizing environmental cycles and the reproductive cycles of native species. Ordination of species abundances showed discrete fish communities that reflect the geographical separation between catchments. Differences between communities are related to opportunities for dispersal, the environmental tolerances of dominant species and the modifying effects of river regulation. Fish communities in lakes exhibited less seasonal variation than riverine communities within the same catchment, indicating the greater seasonal stability of lakes compared with regulated and unregulated river reaches. Management of fish resources needs to include catchment-specific strategies within current State and basin-wide management programmes.
Assessment of statistical models describing individual and group response of pigs to threonine intake

A nitrogen balance experiment was conducted to study the individual and group response of growing pigs to threonine (Thr) intake. A series of fifteen purified diets with increasing concentration of Thr was fed sequentially to nine pigs during a 15-d experimental period. The concentration of Thr ranged from 50 to 140% of its assumed requirement while other essential amino acids were given in a 25 % excess. N retention was related to Thr intake using rectilinear and curvilinear models. The quadratic-plateau model fitted the individual data significantly better (P=0.02) than the linear-plateau model. The R 2 statistic indicated that the group response of pigs to Thr intake was better described by the linear-plateau and quadratic-plateau models than by exponential, saturation kinetics or four-parameter logistic models. Significant differences (P=0.004) were found between individual plateau values in the linear-plateau model while the slopes of the regression lines did not differ. No significant correlation was found between the slope and plateau or breakpoint values of the linear-plateau model. Marginal efficiency of Thr utilization derived from the linear-plateau model was 0.67. In the quadratic-plateau model, marginal efficiency of Thr utilization was dependent on Thr intake and ranged from 0.77 (50% of requirement) to 0.42 (100% of requirement). Based on linear-plateau and quadratic-plateau models, daily requirement of Thr for a 45 kg pig was calculated to be 11.5 and 12.1 g, respectively.
Dramatic decline of unionid bivalves in offshore waters of western Lake Erie after infestation by the zebra mussel, Dreissena polymorpha

Unionid bivalves and attached epizoic zebra mussels (Dreissena polymorpha) were collected at one index station in 1989, 1990, and 1991 and at 17 stations in 1991 in offshore waters of western Lake Erie of the Laurentian Great Lakes. Sampling at the index station revealed that the proportion of live unionids declined from 53% in September 1989 to 17% in May–June 1990 and to 0% in September 1990: this 100% mortality coincided with heavy infestation by zebra mussels. Quantitative sampling with a Ponar grab at the 17 stations in 1991 revealed a widespread and dramatic reduction in unionid populations. In 1982, five unionid species occurred at 35% of the stations at a density of 4/m2, whereas in 1991, no live unionid species were found. Qualitative sampling with an epibenthic sled at the 17 stations in 1991 yielded only 4 live specimens of 2 species (Amblema plicata plicata and Fusconaia flava) and 187 dead specimens of 10 species. These and other results indicate that unionid populations are being negatively .
An inequality for the number of periods in a word

We prove an inequality for the number of periods in a word x in terms of the length of x and its initial critical exponent. Next, we characterize all periods of the length-n prefix of a characteristic Sturmian word in terms of the lazy Ostrowski representation of n, and use this result to show that our inequality is tight for infinitely many words x. We propose two related measures of periodicity for infinite words. Finally, we also consider special cases where x is overlap-free or squarefree.
DartMinHash: Fast Sketching for Weighted Sets

Weighted minwise hashing is a standard dimensionality reduction technique with applications to similarity search and large-scale kernel machines. We introduce a simple algorithm that takes a weighted set $x \in \mathbb{R}_{\geq 0}^{d}$ and computes $k$ independent minhashes in expected time $O(k \log k + \Vert x \Vert_{0}\log( \Vert x \Vert_1 + 1/\Vert x \Vert_1))$, improving upon the state-of-the-art BagMinHash algorithm (KDD '18) and representing the fastest weighted minhash algorithm for sparse data. Our experiments show running times that scale better with $k$ and $\Vert x \Vert_0$ compared to ICWS (ICDM '10) and BagMinhash, obtaining $10$x speedups in common use cases. Our approach also gives rise to a technique for computing fully independent locality-sensitive hash values for $(L, K)$-parameterized approximate near neighbor search under weighted Jaccard similarity in optimal expected time $O(LK + \Vert x \Vert_0)$, improving on prior work even in the case of unweighted sets.
