Maximal Lp-regularity for a second-order differential equation with unbounded intermediate coefficient
No full textWe consider the following equation −y 00 + r (x) y 0 + q (x) y = f(x), where the intermediate coefficient r is not controlled by q and it is can be strong oscillate. We give the conditions of well-posedness in Lp (−∞, +∞) of this equation. For the solution y, we obtained the following maximal regularity estimate: y 00 p + ry0 p + kqykp ≤ C k f kp where k · kp is the norm of Lp (−∞, +∞)
Resource utilization by the ATLAS High Level Trigger during 2010 and 2011 LHC running
No full textIn 2010 and 2011, the ATLAS experiment successfully recorded data from LHC collisions with high efficiency and excellent data quality. ATLAS employs a three-level trigger system to select events of interest for physics analyses and detector commissioning. The trigger system consists of a custom-designed hardware trigger at level-1 and software algorithms at the two higher levels. The trigger selection is defined by a trigger menu which consists of more than 300 individual trigger signatures, such as electrons, muons, particle jets, etc. An execution of a trigger signature incurs computing and data storage costs. Th composition of the deployed trigger menu depends on the instantaneous LHC luminosity, the experiment's goals for the recorded data, and the limits imposed by the available computing power, network bandwidth and storage space. This paper describes a trigger monitoring framework for assigning computing costs for individual trigger signatures and trigger menus as a whole. These costs can be extrapolated to higher luminosity allowing development of trigger menus for a higher LHC collision rate than currently achievable

Rabies and cystic echinococcosis control: humanitarian project in Kazakhstan of Rotary international
No full textIntroduction. In this paper are summarized the first results of an humanitarian project of Rotary International with the collaboration of the University of Bologna to control Rabies and Cystic Echinococcosis in Kazakhstan. A pilot project have been started in three small villages near the city of Almaty due to the dramatic situation of the two diseases in man and animals all over the Country (1,2,3).
Materials and methods. Pivots of project, in this first phase, were the dogs and the health education. Dogs enlisted were vaccinated against Rabies (European commercial dead vaccine) and treated against Echinococcus granulosus with praziquantel each two months. Health education was implemented with the distribution of a simple leaflet about echinococcosis control ad hoc realized and translated in Russian. Moreover, to obtain information on dog/owner/environment relationships an anamnestic form was filled. Finally on 26 (16%) of the enlisted dogs vaccination procedure was validated by testing for rabies antibodies (SNT).
Result and comments. In one year of field activity were enlisted 157 dogs. Results draw from the anamnestic forms showing an higher number of male dogs (62%) with a low life expectation (3 years) and utilized mainly for guard (88%). Cross breed is prevalent (66 %), as expected in a rural area, as well as the alimentation with cooking waste (89 %) and the freedom to range. All dogs had a good clinical appearance even if only 69 (44%) were previously vaccinated and 44 (29%) were treated against parasites. Veterinary care were demanded, in case of illness, only by 25 % of the owners. Livestock breed by the owner of dogs were mainly cattle (55 %) and sheep (19 %), respectively. The 50% of the dogs tested for the rabies antibodies had non protective values (< 0.5IU/ml) suggesting an improper intervention and the need of a more pressing mark of the activity. In this field it my be considered a good indicator for the project running. Each family, in the involved villages, received the leaflet and many people demonstrated to know the disease. The participation was voluntary and a big surprise was that the locals have received and treated us most kindly
The Resource utilization by ATLAS High Level Triggers. The contributed talk for the Technology and Instrumentation in Particle Physics 2011.
No full textIn 2010 the ATLAS experiment has successfully recorded data from LHC collisions with high efficiency and excellent data quality. ATLAS employs a three-level trigger system to select events of interest for physics analyses and detector commissioning. The trigger system consists of a custom-designed hardware trigger at level-1 (L1) and software algorithms executing on commodity servers at the two higher levels: second level trigger (L2) and event filter (EF). The corresponding trigger rates are 75~kHz, 3~kHz and 200~Hz. The L2 uses custom algorithms to examine a small fraction of data at full detector granularity in Regions of Interest selected by the L1. The EF employs offline algorithms and full detector data for more computationally intensive analysis. The trigger selection is defined by trigger menus which consist of more than 500 individual trigger signatures, such as electrons, muons, particle jets, etc. An execution of a trigger signature incurs computing and data storage costs. A composition of the deployed trigger menu depends on instantaneous LHC luminosity, experiment's goals for recorded data and limits imposed by the available computing power, network bandwidth and storage space. We have developed a monitoring infrastructure to assign computing cost for individual trigger signatures and the trigger menu as whole. These costs can be extrapolated to higher luminosity allowing development of trigger menus for a higher LHC collision rate than currently achievable. Total execution times of L2 and EF algorithms are monitored to ensure that sufficient computing resources are available to process events accepted by lower trigger levels. For events accepted by the L1, data fragments are buffered by the Readout System (ROS) which provides them on demand to the L2 algorithms. The rate and volume of these data requests by the individual L2 algorithms are also monitored, and the trigger menus are corrected when necessary, to prevent exceeding a maximum allowed ROS request rate. In addition, patterns for cabling readout links from sub-detectors front-ends are checked for potential inefficiencies which could limit ROS performance. Finally, an acceptance rate of individual signatures at higher luminosity is computed using specially recorded detector data. The acceptance rate of the entire menu is also computed taking into account correlations between signatures. In this presentation we describe the software infrastructure for measuring resource utilization of the ATLAS High Level Trigger. We also describe the procedure and tools employed by ATLAS in 2010 to develop trigger menus as the LHC collision rate increased by several orders of magnitude

A chronological framework connecting the early Upper Palaeolithic across the Central Asian piedmont
No full textCentral Asia has delivered significant paleoanthropological discoveries in the past few years. New genetic data indicate that at least two archaic human species met and interbred with anatomically modern humans as they arrived into northern Central Asia. However, data are limited: known archaeological sites with lithic assemblages generally lack human fossils, and consequently identifying the archaeological signatures of different human groups, and the timing of their occupation, remains elusive. Reliable chronologic data from sites in the region, crucial to our understanding of the timing and duration of interactions between different human species, are rare. Here we present chronologies for two open air Middle to Upper Palaeolithic (UP) sequences from the Tien Shan piedmont in southeast Kazakhstan, Maibulak and Valikhanova, which bridge southern and northern Central Asia. The chronologies, based on both quartz optically stimulated luminescence (OSL) and polymineral post-infrared infrared luminescence (pIR-IRSL) protocols, demonstrate that technological developments at the two sites differ substantially over the ∼47–19 ka time span. Some of the innovations typically associated with the earliest UP in the Altai or other parts of northeast Asia are also present in the Tien Shan piedmont. We caution against making assumptions about the directionality of spread of these technologies until a larger, better defined database of transitional sites in the region is available. Connections between the timing of occupation of regions, living area setting and paleoenvironmental conditions, while providing hypotheses worth exploring, remain inconclusive. We cautiously suggest a trend towards increasing occupation of open air sites across the Central Asian piedmont after ∼40 ka, corresponding to more humid climatic conditions which nevertheless included pulses of dust deposition. Human occupation persisted into the Last Glacial Maximum, despite cooler, and possibly drier, conditions. Our results thus provide additional data to substantiate arguments for occupation of Central Asia
The solvability conditions for the second order nonlinear differential equation with unbounded coefficients in L2(R)
No full textThe article deals with the existence of a generalized solution for the second order nonlinear differential equation in an unbounded domain. Intermediate and lower coefficients of the equation depends on the required function and considered smooth. The novelty of the work is that we prove the solvability of a nonlinear singular equation with the leading coefficient not separated from zero. In contrast to the works considered earlier, the leading coefficient of the equation can tend to zero, while the intermediate coefficient tends to infinity and does not depend on the growth of the lower coefficient. The result obtained formulated in terms of the coefficients of the equation themselves; there are no conditions on any derivatives of these coefficients
