description: With the rise of Software Defined Networks (SDN), there is growing interest in dynamic and centralized traffic engineering, where decisions about forwarding paths are taken dynamically from a network-wide perspective. Frequent path reconfiguration can significantly improve the network performance, but should be handled with care, so as to minimize disruptions that may occur during network updates. In this paper we introduce Time4, an approach that uses accurate time to coordinate network updates. Time4 is a powerful tool in softwarized environments, that can be used for various network update scenarios. Specifically, we characterize a set of update scenarios called flow swaps, for which Time4 is the optimal update approach, yielding less packet loss than existing update approaches. We define the lossless flow allocation problem, and formally show that in environments with frequent path allocation, scenarios that require simultaneous changes at multiple network devices are inevitable. We present the design, implementation, and evaluation of a Time4-enabled OpenFlow prototype. The prototype is publicly available as open source. Our work includes an extension to the OpenFlow protocol that has been adopted by the Open Networking Foundation (ONF), and is now included in OpenFlow 1.5. Our experimental results show the significant advantages of Time4 compared to other network update approaches, and demonstrate an SDN use case that is infeasible without Time4.

description: New estimates for eigenvalues of non-self-adjoint multi-dimensional Schrödinger operators are obtained in terms of $L_{p}$-norms of the potentials. The results extend and improve those obtained previously. In particular, diverse versions of an assertion conjectured by Laptev and Safronov are discussed. Schrödinger operators with slowly decaying potentials are also considered.

description: We obtain an energy inequality on null surfaces $u=const$ in the Bondi-Sachs formalism. We show that for a sufficiently regular event horizon $H$ there is an affine radial coordinate which is constant on $H$. Then the energy inequality can be prolongated to the horizon giving an estimation which is closely related to the Penrose inequality. We test it for the Kerr solution written in the Fletcher-Lun coordinates.

description: Charge transfer compounds with the general formula (TTF)4CuX2 (TTF = tetrathiafulvalene
description: X = Cl, Br) may be prepared by the reaction of excess TTF with Cu(sparteine)X2 in methylene chloride. The semiconducting compounds have low activation energies and relatively high electrical conductivities. Magnetic susceptibility, EPR, and spectroscopic data provide evidence that copper has been reduced to copper(I) in the complexes, and that the unpaired electrons are delocalized over columnar stacks of TTF. Reaction of TTF with [Cu(2-aminoethylpyridine)Cl2] or [Cu(nicotine)C12] in methylene chloride yielded (TTF)2CuCI2, while reaction of TTF with [Cu4OCl6(2-picoline)4] yielded (TTF)CUCI2.

LIQUID ROCKET ENGINE
COMBUSTION INSTABILITIES

description: REST (Rocket Engine Stability initiative) is a European Initiative to coordinate and share research activities and improve the understanding of combustion instability in Liquid Propellant Rocket engines. REST test case HF-10 was a numerical test case defining a set up for the calculation of a methane coaxial flame which all participants were invited to use with their respective codes and models. Ariane Group Ottobrunn used an URANS model with a simple 1 step chemistry. The simple chemistry model usually leads to an over-prediction of the temperature. This was impeded by setting a simple temperature limiter that stops the reaction when temperature exceed the desired level. Due to the expected flow effects to the excitations a relatively fine grid, especially close to the injector, was used. All three proposed, excited configurations were calculated (2x LOX mass flow excitation (at two different frequencies), 1x CH4 mass flow excitation) plus the steady state case. The evaluation of the results shows large differences in the sensitivity of the flame to the different ways of excitation and frequencies. Both phase averaged and the mean results were calculated and evaluated for different quantities like temperature or reaction rates. The results show a more intense reaction to LOX mass flow excitation compared to CH4 mass flow excitation. For LOX mass flow excitation at lower frequencies, large symmetry breaking structures develop and propagate downstream. The distortion of the flame leads to a massive shortening which is clearly visible both in phase averaged and mean flow field. For higher frequencies, this effect is less pronounced. For CH4 mass flow excitation, only very minor effects on the flame can be observed. The reaction of the flame is limited to barely visible changes in the vicinity of the injector. This holds true both for phase averaged and globally averaged flow fields. Despite of the relatively low resolving URANS model and the simple chemistry, the simulations were capable of showing many of the effects that are known for such excited configurations. The numerical effort was mainly driven by the mesh. An implicit scheme was used by the solver (Ansys CFX). This permitted large time steps, requiring sub-iterations, however. Doing so, each case could be handled with in a few days on a moderate three digit amount of CPUs
Strong exchange coupling between the lanthanide ions and the phthalocyaninato ligand radical in bis(phthalocyaninato)lanthanide sandwich compounds

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: A series of lanthanide phthalocyanine sandwich compounds with the formula [ (Pc 2-)Ln III (Pc 1- ) ] have been synthesized and characterized. To a first approximation, the lanthanide ions exist in their normal trivalent state, while one of the phthalocyanine ligands exists in the normal dianionic state and the other exists as a monoanionic phthalocyanine radical. It is obvious from the magnetic behavior of these compounds that there is a strong magnetic interaction between the lanthanide f-electrons and the phthalocyanine radical electron. Both antiferro- and ferromagnetic ground states have been observed in this series of compounds which depends on the symmetry and occupancy of the magnetic orbitals on the lanthanide ion. In some cases both the antiferro- and ferromagnetic states of a single system are observed in the temperature range studied. In these cases, the energy separation between states has been evaluated from the magnetic data.
Why is Epistemic Evaluation Prescriptive?
Creators: name: Nolfi, Kate
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Epistemic evaluation is often appropriately prescriptive in character because believers are capable of exercising some kind of control—call it doxastic control—over the way in which they regulate their beliefs. An intuitively appealing and widely endorsed account of doxastic control—the immediate causal impact account—maintains that a believer exercises doxastic control when her judgments about how she ought to regulate her beliefs in a particular set of circumstances can cause the believer to actually regulate her beliefs in those circumstances as she judges she ought to. I show here that the immediate causal impact account is ultimately untenable. Nevertheless, the immediate causal impact account gets something important about the nature of doxastic control right: exercising doxastic control involves being such that one’s conception of ideal belief regulation somehow shapes the way in which one actually regulates one’s beliefs. Thus, I develop here an alternative account according to which, insofar as she exercises doxastic control, a believer’s conception of ideal belief regulation shapes the way in which she actually believes by exerting causal power directly on her dispositions to regulate her beliefs in certain ways. I defend this alternative against other competitors by showing that it can be extended to supply a unified account of rational control that explains evaluation with respect to the various different norms of rationality that govern the way in which we form, revise, and sustain not only our beliefs, but also our intention, hopes, fears, etc. is often appropriately prescriptive.

description: We introduce Copernicus Complexio (COCO), a high-resolution cosmological N-body simulation of structure formation in the $Λ{\rm CDM}{}$ model. COCO follows an approximately spherical region of radius $\sim 17.4h^{-1}\,{\rm Mpc}$ embedded in a much larger periodic cube that is followed at lower resolution. The high resolution volume has a particle mass of $1.135\times10^5h^{-1}{\rm M}_{\odot}$ (60 times higher than the Millennium-II simulation). COCO gives the dark matter halo mass function over eight orders of magnitude in halo mass; it forms $\sim 60$ haloes of galactic size, each resolved with about 10 million particles. We confirm the power-law character of the subhalo mass function, $\bar{N}(>μ)\proptoμ^{-s}$, down to a reduced subhalo mass $M_{sub}/M_{200}\equivμ=10^{-6}$, with a best-fit power-law index, $s=0.94$, for hosts of mass $\langle M_{200}\rangle=10^{12}h^{-1}{\rm M}_{\odot}$. The concentration-mass relation of COCO haloes deviates from a single power law for masses $M_{200}

LIQUID ROCKET ENGINE
COMBUSTION INSTABILITIES

description: REST (Rocket Engine Stability initiative) is a European initiative to coordinate and share research activities and to improve the understanding of combustion instability in Liquid Propellant Rocket engines. This is done in different kinds of workshops, e.g. modeling workshops. In such modeling workshops, the participants are invited to treat common test cases for benchmarking their tools. REST test case HF-10 is a numerical test case defining a set up for the calculation of a methane coaxial flame which all participants were invited to use with their respective codes and models. The test case was based on an engine demonstrator defined in the frame of the DLR SFB TRR 40 and can be considered as representative for a full scale rocket engine. The demonstrator uses coaxial injection elements burning LOX CH4 at 100bar. In order to keep the numerical effort limited, one singe element is calculated for a cross section of representative size and periodic boundary conditions. A steady state flow field and 3 excited calculations were demanded as test cases: CH4 modulation with +-10% @ 5kHz LOX modulation with +-10% @ 5kHz and 1kHz The participants contributed as many of the calculations as they were willing to. The participants performing the test cases are both industrial and scientific institutions, working on commercial and in-house codes. Each participant used his own numerical approaches such as LES, URANS. Different chemistry models and different numerical schemes were employed. Most results which are compiled in this paper are also presented in detail in individual publications. The synthesis presented here permits to compare the works on a global level. This is of particular interest due to the variety of numerical approaches and models employed. The results have been post-processed in a comparable manner using prescribed views and color maps by all participants. This eases the direct visual comparison. The focus is set on flame shape, reaction rates and temperature. Due to the common post processing, the results can be presented in a clear manner both for mean and phase averaged solution. As far as possible, the results are presented side by side to permit an easy comparison. Some differences in flame structure, flame dynamics and other parameters are visible and highlight the particularities and capabilities of the modelling.

Year: 2015
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: According to classical grain growth laws, grain growth is driven by the minimization of surface energy and will continue until a single grain prevails. These laws do not take into account the lattice anisotropy and the details of the microscopic rearrangement of mass between grains. Here we consider coarsening of body-centered cubic polycrystalline materials in three dimensions using the phase field crystal model. We observe as function of the quenching depth, a cross over between a state where grain rotation halts and the growth stagnates and a state where grains coarsen rapidly by coalescence through rotation and alignment of the lattices of neighboring grains. We show that the grain rotation per volume change of a grain follows a power law with an exponent of $-1.25$. The scaling exponent is consistent with theoretical considerations based on the conservation of dislocations.

description: Purpose: To observe hypogonadal men undergoing testosterone replacement therapy (TRT) and assess racial differences in hypogonadal improvement and prostate-specific antigen (PSA) levels. Materials and Methods: In a retrospective analysis, 75 hypogonadal men were followed for an average 34 months after initiating TRT. Total testosterone and PSA levels were assessed every 6 months, and patients diagnosed with prostatitis or prostate cancer during treatment were excluded. Results: For 16 African American men, the average age at diagnosis of hypogonadism was 53.5 years, compared with 57.8 years in 59 Caucasian men (p = NS). Pre- and post-treatment testosterone was 219 ng/dL and 310 ng/dL in African American men, and 247 ng/dL and 497 ng/dL in Caucasian men (p = NS). Symptomatic response was 81% in African American men and 93% in Caucasian men (p = NS). Baseline PSA level was 1.32 ng/mL in African American men and 1.27 ng/mL in Caucasian men, and there was no significant difference in PSA between racial groups at 6-month intervals, although there was a small decreasing trend in the PSA of African Americans compared with Caucasians. Conclusions: Hypogonadal African American men have a similar normalization of testosterone and symptomatic response as hypogonadal Caucasian men, and PSA levels remain stable over time in both groups. In this hypogonadal cohort, in contrast to studies of eugonadal men, higher PSA levels in African Americans were not observed.

description: Extreme climate events have increased in recent years, leading to huge losses of agricultural products. A field study of a two-year organic horticultural rotation (2015–16 and 2016–17) was conducted to evaluate the effects of soil hydraulic arrangement and cover crops management on cash crops productivity, soil carbon (C) and nitrogen (N) sequestration, greenhouse gas (GHG) emissions and C balance. The experiment consisted of two simultaneous rotation systems, a cauliflower-tomato rotation on raised beds and a zucchini-lettuce one on flat strips between them, combined with cover crops as living mulch or break crops. The results pointed out that the use of proper hydraulic arrangements may partially reduce the exposure of crops to extreme climate events, like heavy rains and floods, allowing the preservation of soil fertility. The cover crops increased the yields and enhanced the soil nutrient pools. Our study showed the important role of cover crops since the soil C stock values were significantly higher when they were used in the rotations. The analysis of the GHG emissions, C balance and C efficiency revealed that combining agro-ecological and conservation practices can improve environmental sustainability in organic farming in the Mediterranean area, allowing farmers to maintain/increase their agricultural systems sustainability.

description: We investigate the dynamics of dust grains with various sizes in protoplanetary disk winds driven by magnetorotational turbulence, by simulating the time evolution of the dust grain distribution in the vertical direction. Small dust grains, which are well coupled to the gas, are dragged upward with the upflowing gas, while large grains remain near the midplane of a disk. Intermediate--size grains float at several scale heights from the midplane in time-averated force balance between the downward gravity and the upward gas drag. For the minimum mass solar nebula at 1 AU, dust grains with size of 20 -- 40 $μm$ float at 5-10 scale heights from the midplane. Considering the dependence on the distance from the central star, smaller-size grains remain only in an outer region of the disk, while larger-size grains are distributed in a broader region. We also discuss the implication of our result to the observation of dusty material around young stellar objects.

description: We analyze a simple dynamic durable good oligopoly model where sellers are capacity constrained. Two incumbent sellers and potential entrants choose their capacities at the start of the game. We solve for equilibrium capacity choices and the (necessarily mixed) pricing strategies. In equilibrium, the buyer splits the order with positive probability to preserve competition
description: thus it is possible that a high and low price seller both have sales. Sellers command a rent above the value of unmet demand by the other seller. A buyer would benefit from either a commitment not to buy in the future or by hiring an agent with instructions to buy always from the lowest priced seller.

description: Recent advancements in deep learning have greatly advanced the field of infrared small object detection (IRSTD). Despite their remarkable success, a notable gap persists between these IRSTD methods and generic segmentation approaches in natural image domains. This gap primarily arises from the significant modality differences and the limited availability of infrared data. In this study, we aim to bridge this divergence by investigating the adaptation of generic segmentation models, such as the Segment Anything Model (SAM), to IRSTD tasks. Our investigation reveals that many generic segmentation models can achieve comparable performance to state-of-the-art IRSTD methods. However, their full potential in IRSTD remains untapped. To address this, we propose a simple, lightweight, yet effective baseline model for segmenting small infrared objects. Through appropriate distillation strategies, we empower smaller student models to outperform state-of-the-art methods, even surpassing fine-tuned teacher results. Furthermore, we enhance the model's performance by introducing a novel query design comprising dense and sparse queries to effectively encode multi-scale features. Through extensive experimentation across four popular IRSTD datasets, our model demonstrates significantly improved performance in both accuracy and throughput compared to existing approaches, surpassing SAM and Semantic-SAM by over 14 IoU on NUDT and 4 IoU on IRSTD1k. The source code and models will be released at https://github.com/O937-blip/SimIR.

description: We show that the observed fluxes, spectra and sky distributions of the high energy diffuse backgrounds of astronomical neutrinos, gamma rays and cosmic ray positrons satisfy simple relations expected from their common production in hadronic collisions of high energy cosmic rays (CRs) with diffuse matter. This provides compelling evidence that the high energy neutrino, gamma ray, and positron backgrounds have a common origin - hadronic meson production by cosmic rays in our Galaxy and in external galaxies rather than through the decay/annihilation of dark matter particles.

description: In the face of myriad environmental challenges associated with industrial agriculture, some farmers and researchers have looked to diversified farming systems as a promising alternative. Despite well-documented ecological benefits, diversification practices remain rare in many regions of the U.S, even amongst organic farmers. Our study focuses on organic farmers in the Central Coast region of California, an area that has played a crucial role in the rise of organic agriculture over the last several decades. Through 20 interviews with farmers who all grow lettuce and 8 interviews with technical assistance providers, we investigate the persistent barriers that growers in this region face in adopting diversification practices including cover cropping, compost application, crop rotation, insectary strips, and hedgerows. We find that high land rents, the predominance of short-term leases, stringent food safety standards, and other supply chain pressures significantly hamper the adoption of diversification practices. In order to surmount these barriers and increase adoption, solutions must be pursued at three interconnected levels: innovation at the farm level, and policy change at the technical and structural levels. Locally-informed, integrated, and innovative policies across these three levels must be explored to support the creation of a more resilient, sustainable, and equitable food system.

description: We present the first joint spectral and imaging analysis of hard X-ray (HXR) emission from 3 microflares observed by the Nuclear Spectroscopic Telescope ARray (NuSTAR) and Solar Orbiter/Spectrometer/Telescope for Imaging X-rays (STIX). We studied 5 joint spectra from GOES A7, B1 and B6 class microflares from active region AR12765 on 2020 June 6 and 7. As these events are very bright for NuSTAR, resulting in extremely low (<1%) livetime, we introduce a pile-up correction method. All five joint spectra were fitted with an isothermal model finding temperatures in the 9-11 MK range. Furthermore, three joint spectra required an additional non-thermal thick-target model finding non-thermal powers of $10^{25}$-$10^{26}$ erg s$^{-1}$. All the fit parameters were within the ranges expected for HXR microflares. The fit results give a relative scaling of STIX and NuSTAR mostly between 6-28% (one outlier at 52%) suggesting each instrument are well calibrated. In addition to spectral analysis, we performed joint HXR imaging of the June 6 and one of the June 7 microflares. In NuSTAR's field of view (FOV), we observed two separate non-thermal sources connected by an elongated thermal source during the June 6 microflares. In STIX's FOV (44 degrees W with respect to NuSTAR), we imaged thermal emission from the hot flare loops which when reprojected to an Earth viewpoint matches the thermal sources seen with NuSTAR and in the hotter EUV channels with the Solar Dynamic Observatory's Atmospheric Imaging Assembly.

description: We constrain the Higgs boson (Yukawa) coupling to quarks in the first two generations in the $H\to ZZ$ final states. Deviation of these couplings from the Standard Model values leads to change in the Higgs boson width and in the cross sections of relevant processes. In the Higgs boson resonance region, an increased light Yukawa coupling leads to an increased Higgs boson width, which in turn leads to a decreased cross section. In the off-shell region, increased Yukawa couplings result in an enhancement of the Higgs boson signal through $q\bar{q}$ annihilation. With the assumption of scaling one Yukawa coupling at a time, this study is conceptually simple and yields results with the same order of magnitude as the tightest in the literature. The study is based on results published by the CMS experiment at the LHC in 2014, corresponding to integrated luminosities of $5.1\ifb$ at a centre-of-mass energy $\sqrt{s}=7\tev$ and $19.7\ifb$ at $8\tev$.

description: Formation of localized magnetic states in a metallic host is a classic problem ofcondensed matter physics formalized by P. W. Anderson within the so called single impurity Anderson model (SIAM). The general picture in a host of a simple one-band metal is that a large Hubbard $U$ in the impurity orbital is pre-requisite for the formation of localized magnetic states. In recent years three dimensional (3D) Dirac solids have emerged the hallmark of which is strong spin-orbit interaction. In this work we show that such a strong spin-orbit interaction allows to form localized magnetic states even with small values of Hubbard $U$. This opens up the fascinating possibility of forming magnetic states with $s$ or $p$ orbital impurities -- different from traditional paradigms of $d$ or $f$ orbital based magnetic moments.

description: We study the prospects for long-lived charged particle (LLCP) searches at current and future LHC runs and at a 100 TeV pp collider, using Drell-Yan slepton pair production as an example. Because momentum measurements become more challenging for very energetic particles, we carefully treat the expected momentum resolution. At the same time, a novel feature of 100 TeV collisions is the significant energy loss of energetic muons in detectors. We use this to help discriminate between muons and LLCPs. We find that the 14 TeV LHC with an integrated luminosity of 3 ab$^{-1}$ can probe LLCP slepton masses up to 1.2 TeV, and a 100 TeV pp collider with 3 ab$^{-1}$ can probe LLCP slepton masses up to 4 TeV, using time-of-flight measurements. These searches will have striking implications for dark matter, with the LHC definitively testing the possibility of slepton-neutralino co-annihilating WIMP dark matter, and with the LHC and future hadron colliders having a strong potential for discovering LLCPs in models with superWIMP dark matter.

description: The influence of size differences, shape, mass and persistent motion on phase separation in binary mixtures has been intensively studied. Here we focus on the exclusive role of diffusivity differences in binary mixtures of equal-sized particles. We find an effective attraction between the less diffusive particles, which are essentially caged in the surrounding species with the higher diffusion constant. This effect leads to phase separation for systems above a critical size: A single close-packed cluster made up of the less diffusive species emerges. Experiments for testing of our predictions are outlined.

Time Present and Time Past: Rivalry and the Duration of Interstate Wars, 1846-1985
Creators: name: Long, Stephen

Year: 2003

description: This paper sits at the intersection of the rivalry, war duration, and bargaining literatures, suggesting that histories of armed conflict between states increase war duration through their effects on the selectorate and the wartime bargaining process. I argue that the historical relationship between two states plays an integral role in the duration of future conflict. Specifically, historical conflict between states intensifies the preference of national selectorates for military victory and narrows the range of negotiated settlements that leaders might pursue while still maintaining domestic political support. I employ Bennett and Stam’s (1996) ex ante data set and Crescenzi and Enterline’s (2001) International Interaction Score to provide an empirical test of the generalizability of appropriately coded historical interaction to the topic of war duration. Contradicting earlier studies, the results of this analysis show that a properly operationalized measure of rivalry has significant and positive effects on war duration.
R2CA Second Yearly Activity Report

Year: 2021
Subjects: LOCA SGTR accidents, DBA DEC-A conditions, code simulations

description: In this report were described the work status and the main progresses accomplished by each of the consortium partner during the second year of the project covering the period September 2020-August 2021. One of the main advances of the project during this period was the finalization of all accidental scenario calculations covering LOCA and SGTR accidents under DBA and DEC-A conditions, the results of which were recorded in individual technical reports. About 48 scenarios were calculated on different kinds of reactor designs (VVERs, PWRs, EPR and BWR). A synthesis of these results is currently in progress and should make it possible to highlight the possible ways of improvement in the calculation chains to allow a better estimation of the radiological consequences of these accidental sequences. All the work that will allow to highlight the improvements made during the project and prepare the database has also been finalized (i.e. elaboration of simplified calculation tool for radiological consequence evaluation, excel data file for gathering the calculation results).With regard to the work packages dedicated to R&D (i.e. WP3-LOCA & WP4-SGTR) and mainly to the improvements of the modelling of the phenomena occurring during LOCA & SGTR sequences,substantial progress has already been made and is detailed in this report. In addition to the modelling work and the improvement of the calculation chains, new experimental data and NPP measurements have also been made available to the partners (i.e. on clad H2 uptake, on iodine activity in VVER primary circuit...). In WP5 dedicated to innovation progress has also been made. The bibliographic work allowing to make the status in existing devices, Accidental Management Procedures (AMPs) and diagnostic tools worldwide, in the nuclear field but also more generally in the industrial field has been finalized. Both identification of devices (including instrumentation) of interest and development of some algorithms for the improvement of AMPs have been already performed. Finally for the evaluation of Accident Tolerant Fuel, both identification/collection of thermo-physical/chemical properties and preparatory work on some of the simulation chains that will be used for their evaluation and the associated uncertainties/sensitivity analyses have been made

description: Daminozide (alar), a plant growth retardant, is used in different fruit orchard to make fruits attractive and reduce pre-harvest losses. Previously data demonstrated that acute daminozide exposure affected reproductive fitness and produced neurodegeneration in Drosophila melanogaster. The goal of this study was to determine whether continuous exposure to daminozide affects neuromuscular co-ordination in D. melanogaster as manifested in various behavioral responses. Fruit flies were exposed to 200 or 400 mg/L concentration of daminozide for two successive generations. Treated D. melanogaster were examined for the behaviors indicative of neuromuscular coordination and cognitive abilities, that include climbing, social interaction, adult grooming, migration, flight, male aggression, and adult courtship. Aberrant behavioral responses were noted among treated D. melanogaster of both sexes as evidenced by the following parameters: reduction in flight duration, abnormal social interaction, altered copulatory acts, and over-aggressiveness. Data suggest that daminozide produces impairment in neuromuscular coordination and cognitive ability in Drosophila, which was reflected as altered behavioral patterns. As Drosophila is considered as a reliable in vivo model utilized in toxicity testing, our findings may help us to anticipate and monitor potential daminozide-induced toxicity in animals and humans.
