Stage-aware Scheduling in a Library OS

Scalable high-performance network servers are a requirement in today’s distributed infrastructure. Event-driven concurrency models often provide better scalability properties than multi-threaded servers but many legacy applications still follow the multi-threaded model where each request is handled by a dedicated operating system thread. Recent profiling at Google suggests that the instruction working set of many server applications does not fit into the private i-caches of contemporary processors, causing underutilization of their super-scalar out-of-order pipeline. In a multi-threaded server with an oversized instruction working set, context switches between two request-handler threads are thus likely to cause i-cache misses and subsequent pipeline stalls. We start by analyzing existing approaches to optimize the cache behavior of network servers. One technique applicable to multi-core systems is executing different parts of an application’s code on different cores. By migrating threads to those cores whose caches contain the threads’ current instruction working set, the application’s code is effectively spread over the system’s private i-caches and code misses are greatly reduced. Proof-of-concept work at the KIT OS group shows the potential of this technique, but the implementation does not scale to multiple clients and cores. In this thesis, we therefore propose that the spreading technique described above must be tightly integrated with the OS thread scheduler. We present an unintrusive user-space API that allows partitioning a multi-threaded server’s request handler code path into stages. Our scheduler then dynamically assigns cores to stages and dispatches threads on their current stages’ cores. We evaluate our design and its implementation in the OSv library operating system by adapting the MySQL database management system to our solution. We achieve up to 22% higher throughput caused by a 65% reduction of L2 i-cache misses without having to sacrifice request latency for this improvement.
Factors affecting formation of flocks of unusual size and composition in Black-necked Storks (Ephippiorhynchus asiaticus) in Australia and India

Abstract The Black-necked Stork (Ephippiorhynchus asiaticus) usually occurs singly, in pairs or in family groups, and only very rarely in flocks. We describe records of flocks of this species in the Australian and Indian subspecies and discuss the possible reasons for their occurrence. Records of flocks were fewer from India, but flock-sizes were significantly larger. Factors related to flock formation, such as season, habitat quality and water availability, differed between Australia and India. Flocks occurred predominantly in autumn in Australia, whereas there was no relationship between season and flocking in India. Flock-sizes did not differ seasonally for either subspecies or between subspecies. Flocks were composed either of adults only or combinations of young birds and adults. In Australia, occurrence of different types of flocks was not affected by season or habitat. A combination of season and local habitat conditions appear to be affecting formation of flocks in this species.
Pretreatment biomarkers as prognostic predictors of survival in patients with Pancreatic Cancer treated with Gemcitabine-based Therapy and 5-Fluorouracil: Neutrophil-to-lymphocyte ratio vs Platelet-to-lymphocyte ratio

Although elevated neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been reported to be inverse prognostic predictors of survival in patients with pancreatic cancer (PC), the comparison of their prognostic roles in patients with PC undergoing gemcitabine-based chemotherapy and 5-fluorouracil (5-FU) remains unclear. This study was designed and performed to determine the predictive roles of NLR and PLR in patients diagnosed with PC who underwent one of these two regimens. We retrospectively enrolled 95 patients diagnosed with PC undergoing supportive care, gemcitabine-based chemotherapy or 5-FU therapy from January 2015 to October 2018. Univariate and multivariate Cox regression analyses were done to identify clinicopathological predictors of time to treatment failure (TTF) and overall survival (OS), including pretreatment NLR and PLR. The statistical data showed that pretreatment NLR was significantly associated with metastasis. Among all analyzed variables, pretreatment NLR was an independent prognostic predictor of both TTF and OS of patients with PC, with NLR>4.0 predicting worse survival. PLR, however, didn't independently predict TTF or OS. There were no significant difference in the OS of patients undergoing gemcitabine-based regimens and 5-FU regimens when divided into two subgroups: NLR ≤4.0 and >4.0. In conclusion, pretreatment NLR is a promising independent outcome predictor for patients with PC, while NLR might not be a suitable factor in the selection of regimens for patients with PC.
Chromosome territories, nuclear matrix filaments and inter-chromatin channels: a topological view on nuclear architecture and function

Times are gone when a biochemist might have safely considered the nucleus as a bag in which extended chromatin fibres float around in the nuclear sap with few geometrical constraints. Instead, the nucleus has emerged in recent years as a highly compartmentalized structure. It contains chromosome territories (Cremer et al. 1993) and numerous multi-protein complexes which interact specifically with DNA or RNA and fulfill distinct functional roles in transcription, splicing, replication and repair (Spector 1993; Roth 1995). These nuclear machineries are often found in specific domains, resulting in typical punctuate or speckled distributions of nuclear antigens in immuno-fluorescent labeling experiments (van Driel et al. 1995). To avoid confusion with chromosomal domains (see below) we refer to the latter as non-chromatin domains. Studies of the topological relationships between non-chromatin domains and chromosome territories are still in their infancy (Zirbel et al. 1993). In this essay we will consider the possible role of in vivo networks of nuclear matrix filaments and interchromatin channels in nuclear compartmentalization with spezial reference to the question of their topological relationships with chromosomal domains and non-chromatin domains.
CHICK CARTILAGE COLLAGEN: A NEW TYPE OF α1 CHAIN NOT PRESENT IN BONE OR SKIN OF THE SPECIES

Isolation and chromatography of collagen from chick cartilage revealed an excess of α1 relative to α2-chains. Characterization of the cyanogen bromide peptides from the α1 fraction indicated the presence of two homologous forms of α1. The results suggest that cartilage contains two collagens, one identical to the collagen of skin and bone, the other clearly different requiring the expression of an additional structural gene and possibly containing only α1-chains.
A distributed cache for fast VM booting in tightly interconnected cloud environments

In modern cloud computing environments, elasticity is regarded as one of the most important features. Part of this elasticity is the ability to boot virtual machines quickly to accommodate suddenly emerging workloads. However, booting large numbers of VMs simultaneously in a scalable way is a difﬁcult problem. If the ﬁle system images used for booting are stored in a central location, it will most likely become a bottleneck. Therefore, a distributed solution is necessary. In this thesis, we present a new solution for storing kernel and ramdisk images, as well as loading these images into newly created VMs efﬁciently. Our approach combines a fast and scalable distributed storage system with the high bandwidth and low interconnect latency of a BlueGene/P supercomputer. The client program runs directly inside the hypervisor, thus avoiding virtualization overhead and allowing it to access the memory of the newly created VM directly. We make use of the remote DMA facilities offered by BlueGene’s interconnect to minimize the load of the storage nodes, mitigating the potential bottleneck they pose. The resulting system is both fast and scalable. It can boot large numbers of VMs simultaneously with low delay.
Palette Sparsification Beyond $(\Delta+1)$ Vertex Coloring

A recent palette sparsification theorem of Assadi, Chen, and Khanna [SODA'19] states that in every $n$-vertex graph $G$ with maximum degree $\Delta$, sampling $O(\log{n})$ colors per each vertex independently from $\Delta+1$ colors almost certainly allows for proper coloring of $G$ from the sampled colors. Besides being a combinatorial statement of its own independent interest, this theorem was shown to have various applications to design of algorithms for $(\Delta+1)$ coloring in different models of computation on massive graphs such as streaming or sublinear-time algorithms. In this paper, we further study palette sparsification problems: * We prove that for $(1+\varepsilon) \Delta$ coloring, sampling only $O_{\varepsilon}(\sqrt{\log{n}})$ colors per vertex is sufficient and necessary to obtain a proper coloring from the sampled colors. * A natural family of graphs with chromatic number much smaller than $(\Delta+1)$ are triangle-free graphs which are $O(\frac{\Delta}{\ln{\Delta}})$ colorable. We prove that sampling $O(\Delta^{\gamma} + \sqrt{\log{n}})$ colors per vertex is sufficient and necessary to obtain a proper $O_{\gamma}(\frac{\Delta}{\ln{\Delta}})$ coloring of triangle-free graphs. * We show that sampling $O_{\varepsilon}(\log{n})$ colors per vertex is sufficient for proper coloring of any graph with high probability whenever each vertex is sampling from a list of $(1+\varepsilon) \cdot deg(v)$ arbitrary colors, or even only $deg(v)+1$ colors when the lists are the sets $\{1,\ldots,deg(v)+1\}$. Similar to previous work, our new palette sparsification results naturally lead to a host of new and/or improved algorithms for vertex coloring in different models including streaming and sublinear-time algorithms.
PROGRESS IN THE MOLECULAR ANALYSIS OF PHYTOCHROME

Although Samuel Johnson was not referring to the field of phytochrome-mediated photomorphogenesis in plants, his philosophy has certainly been embraced by investigators in this field judging from the number of recent publications in this area of research. It is, however, not possible to cover all of the reports which have appeared since the beginning of 1984 in a review of reasonable length. Instead I will mainly focus on studies published during the period of January 1984 to June 1985 which have furthered our understanding of the structure and primary molecular mechanism of action of the plant photoreceptor phytochrome. A number of structural and spectroscopic studies on purified or partially-purified phytochrome preparations will be discussed in terms of the relationship of the observed structural features of phytochrome to its possible functional role in plants. For an in depth picture of the field of photomorphogenesis in plants, 1 refer the reader to two recent treatises on the subject (Shropshire and Mohr, 1983; Smith and Holmes, 1984). More personal perspectives on the molecular properties of phytochrome have also recently appeared (Braslavsky, 1984; Quail, 1984; Hershey et al . , 1985; Riidiger et al . , 1985; Song, 1985). The role of calcium in phytochrome action (Roux, 1984; Hepler and Wayne, 1985) and the role of phytochrome in light-mediated gene expression in plants (Tobin and Silverthorne, 1985) have also been reviewed. Light-mediated chloroplast movement, the effects of blue/UV light on phytochrome mediated responses or phytochrome regulation of enzyme activity in plants will not be discussed here. These topics have recently been reviewed (see Haupt and Wagner, 1984; Mohr, 1985; and Sharma, 1985; respectively).
Confronting our FEERs: a Bayesian-model-selection-based robustness analysis

This paper reviews the Fundamental Equilibrium Exchange Rate (FEER) empirical modeling methodology, with a view to assessing its robustness to underlying assumptions and applicability. We show that the effect of model uncertainty on the individual “ingredients” of the FEER is very large and that there is substantial heterogeneity across countries, which makes panel-based estimation and calibration methods unsuitable. Furthermore, we find that the configuration of trade elasticities for many countries is such that the current account response to real effective exchange rate changes is very sluggish, sometimes even paradoxical, with an appreciation leading to a current account improvement. Finally, we show that due to its mechanistic structure, the FEER model is extremely sensitive to uncertainty on the underlying trade elasticities and current account norm estimates.

IRP Theory based UPQC for Power Quality Profile Enhancement in Distribution System

Power system network will never operate under ideal conditions but contains power quality problems. FACTS based controllers like DVR, DSTATCOM and APF (active power filter) are some of the compensating devices used to improve power quality. UPQC (unified power quality conditioner) is a back-to-back converter topology with common DC-link voltage employed to improve power quality. This paper presents multi-level (three-level) UPQC as power quality conditioner in distribution system. The pulses from hysteresis control trigger UPQC where reference currents are generated using IRP (instantaneous reactive power) control theory for shunt controller and SRF theory for series controller. Analysis is presented with the conditions like UPQC as series compensator conditioning source voltage, UPQC as shunt compensator compensating harmonics in source current and UPQC as (series and shunt) compensator conditioning source voltage and harmonics. System proposed is build and analysis is presented using MATLAB/SIMULINK software.
LIGHT POLARIZATION IN AN ANISOTROPIC MEDIUM IN TERMS OF ROTATIONS

Stokes vector evolution in a homogeneous birefringe nt medium is treated in terms of Cayley-Klein parameters inside 8D space of geometric Clifford al gebra. Scaled to unity, Stokes parameters are compa red with directional cosines of a unit vector in geomet ric algebra and with a unit magnetization vector in NMR. The unusual interpretation of Cayley-Klein paramete rs in matrix optics is regarded as a stimulus to re vise 4D entities in geometric algebra.
Tokens of love: possible diagnostic value of mating plugs and refractive secretory uterine structures in Trichodorus (Diphtherophorina: Trichodoridae)

Within the Trichodoridae, mating plugs have only been recorded from Trichodorus species. They can be observed as a clear plug within the vagina/vulva but may also be present in the uteri. These secretory structures are diverse in size, varying between 4 and 27 μm in length, and in shape from simple unipartite tubular structures to bipartite with a central indentation or with a tail-like end. All mating plugs possess a central canal that can vary in diameter. Within Trichodorus, the shape and structure of the mating plugs can provide additional diagnostic information at species level.
Extinction Rates of North American Freshwater Fauna

Abstract: Since 1900, 123 freshwater animal species have been recorded as extinct in North America. Hundreds of additional species of fishes, mollusks, crayfishes, and amphibians are considered imperiled. Using an exponential decay model, we derived recent and future extinction rates for North American freshwater fauna that are five times higher than those for terrestrial fauna. Assuming that imperiled freshwater species will not survive throughout the next century, our model projects a future extinction rate of 4% per decade, which suggests that North America's temperate freshwater ecosystems are being depleted of species as rapidly as tropical forests.
Susceptibility of Plant Species in Eucalyptus marginata Forest to Infection by Phytophthora cinnamomi

Estimates of the susceptibility of plant species of Eucalyptus marginata forest to Phytophthora cinnamomi were obtained by determining the frequency of plant death and isolation of the pathogen from plants occurring in disease centres in the forest. Plant species were assessed and sampled in 63 active disease centres and 17 old centres infested with P. cinnamomi in E. marginata forest north of the Preston River, south-westem Australia. Impact of P. cinnamomi was intermediate (scattered deaths) in 46% of active disease centres and high (most susceptible plants dead) in 29% of active centres. Impact in 65% of old disease centres was high. Dicotyledons (Magnoliidae) out-numbered monocotyledons (Liliidae). Just over half of the species were from six Magnoliidae families with the largest number of species from the Papilionaceae and Proteaceae. The greatest number of species within the Liliidae were consistently from Haemodoraceae. Families in which species tended not to die in disease centres were mainly from the Papilionaceae, Proteaceae, Mimosaceae, Myrtaceae, Dilleniaceae, Apiaceae and Goodeniaceae for the Magnoliidae and Cyperaceae and Haemodoraceae for the Liliidae. The species which tended to die frequently in disease centres were mainly from the Magnoliidae families: Papilionaceae, Proteaceae and Epacridaceae; and the Liliidae family Xanthorrhoeaceae, as well as the only species of the Zamiaceae. Phytophthora cinnamomi was isolated from 38 of the 105 species occurring in three or more active disease centres, but from only 17 of the 107 species occurring in old centres. For most species in active disease centres, the frequency of isolation of P. cinnamomi from plants was much less than the frequency of recently dead plants sampled. Isolation from plants was less frequent than from adjacent soil. The pathogen was isolated from plant or soil mainly for species of the Papilionaceae, Proteaceae, Epacridaceae and Dilleniaceae of the Magnoliideae and the Iridaceae and Xanthorrhoeaceae of the Liliidae. Cross tabulation of species by frequency of death and isolation of P. Cinnamomi from plant and soil provided the opportunity to classify the response of plant species to infection by P. cinnamorni.
An investigation in Gujarat, India

Energy efficiency is a global priority, but investments in energy efficiency do not always deliver the expected benefits. This paper studies micro-irrigation systems (MIS), a technology thought to reduce the energy required for irrigation by as much as 70 percent. We installed individual meters to directly measure the energy consumption of several hundred farmers in Gujarat, India, and linked this meter data with survey data to yield a comprehensive view into energy use patterns in smallholder agriculture. We document two facts. One, energy use varies widely across farmers, and this variation is unexplained by factors such as farm area or village geography. Two, MIS users in our sample consume 30 to 40 percent more energy than nonusers of MIS. This difference does not apppear to be explained by observable differences across farmers nor by rebound effects, suggesting that the energy impacts of MIS under real-world conditions may be disappointing. While these findings are not causal, they highlight a need for increased attention to details of implementation and further research into the actual benefits of resource-conserving technologies. ∗University of California, Berkeley, nhagerty@berkeley.edu and adzucker@berkeley.edu.

A NOVEL FRAMEWORK FOR SERIAL PROGRAM FULLY AUTO PARALLELIZATION BASED ON OPENACC

On the basis of OpenACC programming standard (for open accelerators), a new framework was proposed, whose name is GENerate OpenACC, or GENACC for short. GENACC can automatically accelerate the serial code. The static program of the source code are analyzed aimed to recognize the hot snippets and analyze the computation property. And finally OpenACC directives are added to the source code in order to accelerate the serial code. According to the experiments on the NPB test set, the results show that GENACC can accurately produce compiler directive, and the source codes show fine performance on different amount of data.
Comparison of external morphological traits of newborns to inner morphological traits of the dam in the double-muscled Belgian Blue Beef breed

In the double-muscled (DM) Belgian Blue Beef (BBB) breed, caesarean section (CS) is used as a routine management tool to prevent dystocia. This practice is criticized on animal welfare grounds. With unassisted (natural) births, difficulties arise because of disproportion between the sizes of the newborn and inner pelvic sizes of the dam. In this study external morphological traits of newborns are compared with inner morphological traits of the dam. Results of this study indicate that in the DM-BBB, CS is the only means to successful calving. Therefore, no calving ease scores are available to select for less dystocia in this breed. Selection for fewer CS must be achieved by focusing on lower birth weight (BW) and decreased muscular conformation at birth, both having a sufficiently high heritability. Simultaneously, pelvic sizes of the dam should be increased. It is very likely that the look of the DM-BBB will change when selecting for less dystocia.
