Abstract:

Particulate emission from internal combustion engines is a complex phenomenon that needs to be understood in order to identify its main factors. To this end, it appears necessary to study the impact of unburned gases, called blow-by gases, which are reinjected into the engine intake system. A series of transient tests demonstrate their significant contribution since the particle emissions of spark-ignition engines are 1.5 times higher than those of an engine without blow-by with a standard deviation 1.5 times greater. After analysis, it is found that the decanter is not effective enough to remove completely the oil from the gases. Tests without blow-by gases also have the advantage of having a lower disparity, and therefore of being more repeatable. It appears that the position of the “endgap” formed by the first two rings has a significant impact on the amount of oil transported towards the combustion chamber by the backflow, and consequently on the variation of particle emissions. For this engine and for this transient, 57% of the particulate emissions are related to the equivalence ratio, while 31% are directly related to the ability of the decanter to remove the oil of the blowby gases and 12% of the emissions come from the backflow. The novelty of this work is to relate the particles fluctuation to the position of the endgap ring.

Abstract:

Abstract The CMS detector will undergo the replacement of its current endcap calorimeter by a new high granularity calorimeter (HGCAL). The new HGCAL will need to withstand much higher radiation levels than the present endcaps. This poses tight requirements on the front-end electronics, including the powering chain. As part of this chain, a low-dropout linear regulator (LDO) has been designed and prototyped for post-regulation for HGCAL, providing extremely low noise and stable power to the analog front-end. We present results from tests of the LDO, including from a detailed irradiation campaign.

Abstract:

Abstract The compact muon solenoid experiment phase 1 hadron calorimeter upgrade implemented the first large-scale application of VTRx modules, radiation and magnetic field tolerant optical transceivers. During run 2 of the Large Hadron Collider, the CMS hadron calorimeter endcap experienced a failure of control communication that revealed a variable manufacturing weakness in the VTRx and affected nearly half of the communication links in the hadron calorimeter endcaps. The CMS hadron calorimeter team provided the first observation of this phenomenon, linked the loss to the VTRx, revealed its temperature dependence, and pioneered the mitigation tactic adopted by other LHC experiments. Aspects of the CMS hadron calorimeter team’s role in the larger VTRx investigations are presented.

Abstract:

AbstractAccurate stress–strain measurements in triaxial tests are critical to compute reliable mechanical parameters. We focus on compliance at the interfaces between the specimen and endcaps, and test specimens under various triaxial conditions using different instrumentation protocols. The tested materials include aluminum, Eagle Ford shale, Berea sandstone, and Jubaila carbonate. Results obtained following common practice reveal that surface roughness at the specimen-endcap interfaces leads to marked seating effects, affects all cap-to-cap based measurements and hinders ultrasonic energy transmission. In particular, cap-to-cap deformation measurements accentuate hysteretic behavior, magnify biases caused by bending and tilting (triggered by uneven surfaces and misalignment), and affect the estimation of all rock parameters, from stiffness to Biot’s α-parameter. Higher confining pressure diminishes seating effects. Local measurements using specimen-bonded strain gauges are preferred (Note: mounting strain gauges on sleeves is ill-advised). We confirm that elastic moduli derived from wave propagation measurements are higher than quasi-static moduli determined from local strain measurements using specimen-bonded strain gauges, probably due to the lower strain level in wave propagation and preferential high-velocity travel path for first arrivals.

Abstract:

We report on the development and performance of a novel track-finding processor for the Level-1 trigger of the CMS endcap muon system. The processor links track segments identified in the cathode-strip chambers of the endcap muon system into complete three-dimensional tracks. It then measures the momentum of the best track candidates from the sagitta measured between three muon chambers in the endcap fringe field. The processor is pipelined at 40 MHz, and has an overall latency of 400 ns. The logic for the prototype is implemented in high-density FPGAs and SRAM memory. It receives approximately 3 gigabytes of data every second from a custom backplane operating at 280 MHz. Test results of the prototype are consistent with expectation.

Abstract:

The Large Hadron Collider and the ATLAS experiment at CERN will explore new frontiers in physics in Run 3 starting in 2022. In the Run 3 ATLAS Level-1 endcap muon trigger, new detectors called New Small Wheel and additional Resistive Plate Chambers will be installed to improve momentum resolution and to enhance the rejection of fake muons. The Level-1 endcap muon trigger algorithm will be processed by new trigger processor boards with modern FPGAs and high-speed optical serial links. For validation and performance evaluation, the inputs and outputs of their trigger logic will be read out using a newly developed software-based readout system. We have successfully integrated this readout system in the ATLAS online software framework, enabling commissioning in the actual Run 3 environment. Stable trigger readout has been realized for input rates up to 100 kHz with a developed event-building application. We have verified that its performance is sufficient for Run 3 operation in terms of event data size and trigger rate. The paper will present the details of the integration and commissioning of the software-based readout system for ATLAS Level-1 endcap muon trigger in Run 3.

Abstract:

We present a method to simulate the double-gap resistive plate chambers (RPC) background particles for the endcap region of a compact muon solenoid/large hadron collider using the geometry and tracking (GEANT) code. We demonstrate that the resistive plate chamber can be described using a realistic Monte Carlo simulation based on the GEANT code and analyzed with physics analysis work station (PAW) interfaces. Sensitivity calculations were performed for γ, e, e+, and such particles in the range 0.1100 MeV for their respective spectra. To evaluate the response of the detector in the large hadron collider (LHC) background environment, the γ, e, and e+ energy spectra expected in the compact muon solenoid (CMS) muon endcap region were taken into account whereas the RPC sensitivity was evaluated as a function of the detector size.PACS Nos.: 7.77.Ka, 7.85.Fv

Abstract:

The Large Hadron Collider is expected to operate with a centre-ofmass energy of 14 TeV and an instantaneous luminosity of 2.0 1034 cm−2s−1 for Run 3 scheduled from 2021 to 2024. In order to cope with the high event rate, an upgrade of the ATLAS trigger system is required. The level-1 endcap muon trigger system identifies muons with high transverse momentum by combining data from fast muon trigger detectors, called Thin Gap Chambers on the Big Wheel. Inner muon detectors (the Small Wheel and the Tile Calorimeter) coincidence was introduced to reduce fake muon contamination. In the ongoing Phase-1 upgrade the present Small Wheel is replaced with the New Small Wheel and additional Resistive Plate Chambers are installed in the inner region of the ATLAS muon spectrometer for the endcap muon trigger. Precision track information from the new detectors can be used as part of the muon trigger logic to enhance the performance significantly. The trigger processor board, Sector Logic, has been upgraded to handle the additional data from the new detectors. The new Sector Logic board has a modern FPGA to make use of Multi-Gigabit transceiver technology, which is used to receive data from the new detectors. The readout system for trigger data has also been re-designed to minimize the use of custom electronics and instead use commercial computers and network switches, by using TCP/IP for the data transfer. The new readout system uses a software-based data-handling. This paper describes the development of the level-1 endcap muon trigger and its readout system for Run 3.

Abstract:

Internet is a source of information which is widely used today. However, the mode of internet abused becomes more various and unavoidable. The internet abused can be done from external or internal networks. Unified Threat Management (UTM) is one of a good solution to secure the networks, because it has several security features such as firewall, proxy, Intrusion Prevention System (IPS) and several other security features in one package. Endian is an UTM distro which is an open source in large community. Besides having some security features, Endian also has some network management features such as DHCP, routing, and VPN. This research put Endian as the center of a network topology that connected to the internal network/LAN, DMZ Server, and Internet Network/WAN. The tests are conducted in the form of implementation of DHCP feature, content filtering, port restrictions on interzone, and the response of the IPS features that exist on the Endian while receiving the attack. The results showed that Endian UTM is quite well in maintaining the security of the networks.

Abstract:

This essay explores how Samuel Beckett’s Endgame portrays the post-apocalyptic consciousness. Using Walker Percy’s semiotic theory to understand the play, this paper positsthat Endgame shows the struggle for individuals to apprehend themselves amidst catastrophe without objectifying themselves. Unable to find a semiotic referent to identify themselves with, people experience alienation as shown in Endgame through Hamm and Clov. Through their struggle to place themselves in their post-apocalyptic context, Hamm and Clov show the futility f rationally ordering life amidst catastrophe.

After the calibration with Bhabha events, the very promising time resolutions of 69 and 60 ps for one-end and two-ends of MRPCs are obtained. The average detection efficiency of two-ends is about 97.5%.

Abstract:

Abstract. We demonstrate that both the current (New Dynamics), and next generation (ENDGame) dynamical cores of the UK Met Office global circulation model, the UM, reproduce consistently, the long-term, large-scale flows found in several published idealised tests. The cases presented are the Held–Suarez test, a simplified model of Earth (including a stratosphere), and a model of a hypothetical Tidally Locked Earth (TLE). Furthermore, we show that using simplifications to the dynamical equations, which are expected to be justified for the physical domains and flow regimes we have studied, and which are supported by the ENDGame dynamical core, also produces matching long-term, large-scale flows. Finally, we present evidence for differences in the detail of the planetary (meridional) flows and circulations resulting from improvements in the ENDGame formulation over New Dynamics. Specifically, we find greater symmetry in the meridional circulations of the Tidally Locked Earth test case using the ENDGame formulation, which is a better match to our physical expectations of the flow for such a slowly rotating Earth-like system.

Abstract:

ABSTRACT The EH domain proteins Pan1p and End3p of budding yeast have been known to form a complex in vivo and play important roles in organization of the actin cytoskeleton and endocytosis. In this report, we describe new findings concerning the function of the Pan1p-End3p complex. First, we found that the Pan1p-End3p complex associates with Sla1p, another protein known to be required for the assembly of cortical actin structures. Sla1p interacts with the first long repeat region of Pan1p and the N-terminal EH domain of End3p, thus leaving the Pan1p-End3p interaction, which requires the second long repeat of Pan1p and the C-terminal repeat region of End3p, undisturbed. Second, Pan1p, End3p, and Sla1p are also required for normal cell wall morphogenesis. Each of the Pan1-4, sla1Δ, andend3Δ mutants displays the abnormal cell wall morphology previously reported for the act1-1 mutant. These cell wall defects are also exhibited by wild-type cells overproducing the C-terminal region of Sla1p that is responsible for interactions with Pan1p and End3p. These results indicate that the functions of Pan1p, End3p, and Sla1p in cell wall morphogenesis may depend on the formation of a heterotrimeric complex. Interestingly, the cell wall abnormalities exhibited by these cells are independent of the actin cytoskeleton organization on the cell cortex, as they manifest despite the presence of apparently normal cortical actin cytoskeleton. Examination of several act1 mutants also supports this conclusion. These observations suggest that the Pan1p-End3p-Sla1p complex is required not only for normal actin cytoskeleton organization but also for normal cell wall morphogenesis in yeast.

Abstract:

This article presents a systematic analysis of military coups following popular mass uprisings in nondemocratic regimes, conceptualized as endgame coups. Drawing on our original, medium- n data set of revolutionary situations, we find that such endgame coups form a distinct type of military intervention in politics. Compared to regular coups, episodes of popular mass contestation prompt conservative interventions in politics of the military’s leadership aimed at preserving the regime’s authoritarian infrastructure. A systematic test of factors characterizing postcoup political trajectories is based on Cox proportional hazard models and provides empirical evidence in contrast to the widely held notion of “democratic coups.” Our findings reveal that endgame coups are conservative rollback coups, executed by military leaderships, that result in continued political instability and illiberal politics.

Abstract:

Drs2p family P-type ATPases (P4-ATPases) are required in multiple vesicle-mediated protein transport steps and are proposed to be phospholipid translocases (flippases). The P4-ATPases Drs2p and Dnf1p cycle between the exocytic and endocytic pathways, and here we define endocytosis signals required by these proteins to maintain a steady-state localization to internal organelles. Internalization of Dnf1p from the plasma membrane uses an NPFXD endocytosis signal and its recognition by Sla1p, part of an endocytic coat/adaptor complex with clathrin, Pan1p, Sla2p/End4p, and End3p. Drs2p has multiple endocytosis signals, including two NPFXDs near the C terminus and PEST-like sequences near the N terminus that may mediate ubiquitin (Ub)-dependent endocytosis. Drs2p localizes to the trans-Golgi network in wild-type cells and accumulates on the plasma membrane when both the Ub- and NPFXD-dependent endocytic mechanisms are inactivated. Surprisingly, the pan1-20 temperature-sensitive mutant is constitutively defective for Ub-dependent endocytosis but is not defective for NPFXD-dependent endocytosis at the permissive growth temperature. To sustain viability of pan1-20, Drs2p must be endocytosed through the NPFXD/Sla1p pathway. Thus, Drs2p is an essential endocytic cargo in cells compromised for Ub-dependent endocytosis. These results demonstrate an essential role for endocytosis in retrieving proteins back to the Golgi, and they define critical cargos of the NPFXD/Sla1p system.
