description: The problem of a fluctuation-induced first-order transition is considered for $p $-wave superconductors. Both an $ε$-expansion about $d=4$ and a large-$n$ expansion conclude that the transition for the physical case $n=6$ in $d=3$ is of first order, as in the s-wave case.

Comments
This unknown species has been identified as Lasioglossum (Hemihalictus) sexstrigatus (Schenck, 1869) in Japan. According to DNA analysis in the present study, the pair-wise sequence divergence between Japanese and European specimens was quite clear (7.3–7.9% between L. sexstrigatus and L. sp. in Table 1). Morphologically, females of this species are slightly different from L. (H.) sexstrigatus as the mesoscutum has a weak tessellation over the entire surface (in contrast, in L. (H.) sexstrigatus, the mesoscutum is nearly smooth on the posterior half).
In the present study, I could not conclude that this unknown species is either undescribed or a known species, but this will be examined in further studies.

Distribution and ecology. This is a rare member of the genus, not long ago described from Thailand (Van Damme et al. 2013), which until recently was considered the only known habitat of the species (Sinev 2016; Neretina et al. 2017). However, the newest analysis of African and Madagascar populations of the related species N. globulosa (indicated under various synonyms in the listed territories) has shown that some of them apparently belong to N. pseudomacronyx (Neretina et al. 2019).Additionally, the latest authors noted that N. globulosa, reported by Fernando (1974) from Sri Lanka, is actually N. pseudomacronyx too. The present checklist is the first indication of N. pseudomacronyx in Vietnam.
The species lifestyle and ecology are unstudied. So far, N. pseudomacronyx was known only from shallow, vegetation-rich swampy localities, including temporary ones (Van Damme et al. 2013; Sinev 2016; Neretina et al. 2017, 2019; Choedchim & Maiphae 2023). In similar habitats, it was also encountered in Vietnam: in a periodically drying, heavily vegetated forest lake and in the root system of floating macrophytes in a floodplain lake (see Appendix 1). The crustacean was most abundant among the roots, where it was found mixed with the sibling species N. globulosa.

This study includes GEANT Monte Carlo simulations of the Cherenkov light transmission efficiency of different types of air-core light guides, as well as analysis of the calorimeter linearity and resolution as a function of energy and impact-point, obtained with 20-200 GeV electron beams from CERN/SPS tests in 2003. Several configurations of the calorimeter have been tested and compared, including different combinations of (i) structures for the active material of the calorimeter (quartz plates and fibres), (ii) various light-guide reflecting materials (glass and foil reflectors) and (iii) photodetector devices (photomultipliers and avalanche photodiodes).

description: The stochastic motion of a two-dimensional vesicle in linear shear flow is studied at finite temperature. In the limit of small deformations from a circle, Langevin-type equations of motion are derived, which are highly nonlinear due to the constraint of constant perimeter length. These equations are solved in the low temperature limit and using a mean field approach, in which the length constraint is satisfied only on average. The constraint imposes non-trivial correlations between the lowest deformation modes at low temperature. We also simulate a vesicle in a hydrodynamic solvent by using the multi-particle collision dynamics technique, both in the quasi-circular regime and for larger deformations, and compare the stationary deformation correlation functions and the time autocorrelation functions with theoretical predictions. Good agreement between theory and simulations is obtained.

Considering the breakdown of Lorentz invariance at finite density, the time and space components are computed separately, and the corresponding results turn out to be: F^t_pi = 82.96 MeV and F^s_pi = 80.29 MeV at mu_c ~ 320 MeV, respectively. Using the in-medium Gell-Mann Oakes-Renner (GOR) relation, we show that the pion mass increases by about 15% at mu_c.

description: This paper reports on the continuation of a long–term experiment on the effects of alternative field traffic systems (STP–random traffic with standard tyre inflation pressure, LTP– random traffic with low tyre inflation pressure and CTF–controlled traffic farming) on soil conditions and crop development as influenced by different tillage depths (DEEP–250 mm, SHALLOW–100 mm and ZERO–tillage), in a randomised 3 x 3 factorial design in 4 replicates launched by Harper Adams University in Edgmond, UK, in 2011. The results from season 2017– 2018 revealed that CTF delivered 8% higher crop yield of winter field bean (Vicia faba) cv. Tundra comparing to STP (p = 0.005), i.e. 4.13 vs 3.82 tonnes ha-1 respectively (at 14% moisture content). The ZERO–tillage plots featured significantly lower plant establishment percentage comparing to shallow and deep tillage: 79% vs 83% and 83% respectively (p = 0.012). The research showed that roots traits differed significantly between contrasting traffic at depths greater than 50mm with p < 0.05 of: tap root biomass, number of lateral roots, biomass of lateral roots as well as total root biomass (tap+lateral roots), delivering significantly greater values of those before mentioned parameters on CTF comparing to STP. Tap root length significantly differed between traffic systems (p < 0.001) giving significantly greater results on CTF comparing to LTP and STP (17.7, 13.4 and 12.6 mm respectively). Significant differences in tap root diameter were found only at the depth of 100 mm (p < 0.001) where again CTF delivered significantly higher root diameter than the remaining 2 traffic systems. In the shallow layer of soil (0–50 mm) a significant difference was found only for tap root biomass, for interactions, where STP ZERO gave significantly higher results than STP SHALLOW and CTF SHALLOW (1.430, 0.733 and 0.716 g respectively).

Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: The software development life cycle (SDLC) is a procedure used to develop a software system that meets both the customer s needs and real-world requirements. The first phase of the SDLC involves creating a conceptual model that represents the involved domain in reality. In requirements engineering, building such a model is considered a bridge to the design and construction phases. However, this type of model can also serve as a basic model for identifying business processes and how these processes are interconnected to achieve the final result. This paper focuses on process modeling in organizations, per se, beyond its application in the SDLC when an organization needs further documentation to meet its growth needs and address regular changes over time. The resultant process documentation is created alongside the daily operations of the business process. The model provides process visualization and documentation to assist in defining work patterns, avoiding redundancy, or even designing new processes. In this paper, a proposed diagrammatic representation models each process using one diagram comprising five actions and two types of relationships to build three levels of depiction. These levels consist of a static description, events, and the behavior of the modeled process. The viability of a thinging machine is demonstrated by re-modeling some examples from the literature.

description: Canada’s 2018-2020 National Action Plan on Open Government (2018-2020 NAP) provides Environment and Climate Change Canada (ECCC) with a mandate to “promote open science and actively solicit feedback from Canadians and federal scientists on their needs with respect to open data and open science” (open science milestone 5.4). To deliver on this commitment, the 2018-2020 NAP proposes two steps: 1) holding 10 open science engagement sessions with federal scientists and invited Canadians across the country, and; 2) publishing a report on identified user needs. Between March 12, 2019 and February 26, 2021, ECCC has investigated the open science needs of federal open science users through direct engagements with the public as well as with federal scientists. This report summarizes ECCC’s findings and fulfills Milestone 5.4 of the 2018-2020 NAP.
Finding Optimal Flows Efficiently

Subjects: subject: Quantum Physics (quant-ph)

description: Among the models of quantum computation, the One-way Quantum Computer is one of the most promising proposals of physical realization, and opens new perspectives for parallelization by taking advantage of quantum entanglement. Since a one-way quantum computation is based on quantum measurement, which is a fundamentally nondeterministic evolution, a sufficient condition of global determinism has been introduced as the existence of a causal flow in a graph that underlies the computation. A O(n^3)-algorithm has been introduced for finding such a causal flow when the numbers of output and input vertices in the graph are equal, otherwise no polynomial time algorithm was known for deciding whether a graph has a causal flow or not. Our main contribution is to introduce a O(n^2)-algorithm for finding a causal flow, if any, whatever the numbers of input and output vertices are. This answers the open question stated by Danos and Kashefi and by de Beaudrap. Moreover, we prove that our algorithm produces an optimal flow (flow of minimal depth.) Whereas the existence of a causal flow is a sufficient condition for determinism, it is not a necessary condition. A weaker version of the causal flow, called gflow (generalized flow) has been introduced and has been proved to be a necessary and sufficient condition for a family of deterministic computations. Moreover the depth of the quantum computation is upper bounded by the depth of the gflow. However, the existence of a polynomial time algorithm that finds a gflow has been stated as an open question. In this paper we answer this positively with a polynomial time algorithm that outputs an optimal gflow of a given graph and thus finds an optimal correction strategy to the nondeterministic evolution due to measurements.

Diagnosis: True stomach plates absent. ODG complex holohepatic.
Genera included in this study: Tritonia, Candiella (see diagnosis below), Marianina, Myrella (see diagnosis below), Tochuina, Tritonicula, Tritonidoxa, Tritoniella and Tritoniopsis.
Remarks: The absence of true stomach plates is considered a plesiomorphy within Tritoniidae, according to the basal position of Pleurobranchidae in our phylogenetic analyses. The term ‘true stomach plates’ is used in this study to differ these structures from other type of cuticular structure, homologous to the stomach plates of marioniids, known as cuticular folds. Cuticular folds are longitudinal folds covered by a thin cuticular layer derived from the cuticular lining of the stomach. Unlike stomach plates, the cuticular folds have a single continuous cuticular layer along their entire length and are not individually detachable (MacFarland 1966). These structures are present in Tochuina (MacFarland 1966), Tritoniella (Wägele 1989), Marianina (Odhner 1963), Tritonia festiva (MacFarland 1966), Tritonia exsulans (MacFarland 1966) and Tritonia odhneri Er.

description: In view of the start up of the 14 TeV pp Large Hadron Collider the quark anti-quark reactions leading to the final states W^+W^-, W^+-Z^0 and Z^0Z^0 are studied, in the frame workn of the Standard Model (SM), using helicity amplitudes. The differential and total cross sections are first evaluated in the parton-parton center of mass system. They are then transformed to their expected behavior in pp collisions through the parton-parton Energy Density Functions which are here derived from the known Parton Density Functions of the proton. In particular the single and joint longitudinal polarizations of the final state di-bosons are calculated. The effect on these reactions from the presence of s-channel heavy vector bosons, like the W' and Z', are evaluated to explore the possibility to utilize the gauge boson pair production as a probe for these 'Beyond the SM' phenomena.

description: The Government of Canada is committed to making federal science, scientific data, and scientists more accessible. The 2020 Annual Report on the Federal Progress in Implementing Open Science and its Benefits describes the Government of Canada’s progress towards that commitment. Progress in implementing open science and the benefits open science can provide is measured through a combination of core metrics designed to capture general progress across all Science-based Departments and Agencies (SBDAs), and supplemental metrics to highlight individual department/agency efforts. Results show an increase in the number of federal peer-reviewed publications available in open access. They also show that although the percentage of overall eligible federal datasets released in the open have only slightly increased, more datasets were made available through Open Maps, an application that provides access to federal geospatial datasets. In terms of public engagement, SBDAs participated in a range of activities allowing Canadians to engage with federal scientists and their research. The reach of federal open science goes far beyond academia. This report shows federal science appears regularly in patents, social media and news outlets. This report also illustrates the benefit associated with open science, for the federal government. Federal science publications that are available in open access are more likely to be cited in other scientific contributions and in patents, which confirms than an open science advantage exists for federal science --meaning that federal scientists who publish in open access can expect their work to be more impactful. While progress in implementing open science has been made, more remains to be done for federal science, scientific data, and scientists to be more accessible. The results of this annual report indicate progress, but fall short of the ambitious targets set out in the Roadmap for Open Science for 2022 and subsequent years. Continued commitment and support of open science is necessary to meet these goals.

Le Rapport annuel de 2020 sur les progrès réalisés par le gouvernement fédéral dans la mise en œuvre de la science ouverte et ses avantages décrit les progrès réalisés par le gouvernement du Canada à l’égard de cet engagement. Les progrès réalisés dans la mise en œuvre de la science ouverte et les avantages que la science ouverte peut offrir sont mesurés au moyen d’une combinaison de paramètres de base conçus pour saisir les progrès généraux dans tous les ministères et organismes à vocation scientifique (MOVS), et de mesures supplémentaires pour mettre en évidence les efforts de chaque ministère ou organisme. Les résultats montrent une augmentation du nombre de publications fédérales évaluées par des pairs disponibles en libre accès. Ils montrent également que même si le pourcentage d’ensembles de données fédéraux admissibles diffusés ouvertement n’a que légèrement augmenté, un plus grand nombre d’ensembles de données ont été rendus disponibles par l’intermédiaire de Cartes ouvertes, une application qui donne accès aux ensembles de données géospatiales fédéraux. En ce qui concerne la participation du public, les MOVS ont participé à une gamme d’activités permettant aux Canadiens de collaborer avec les scientifiques fédéraux et leurs recherches. La portée de la science ouverte fédérale va bien au-delà du milieu universitaire. Ce rapport démontre que la science fédérale apparaît régulièrement dans des brevets, les médias sociaux et les médias d’information. Le rapport illustre également les avantages associés à la science ouverte pour le gouvernement fédéral. Les publications scientifiques fédérales qui sont disponibles en libre accès sont plus probables d’être citées dans d’autres contributions scientifiques et dans des brevets, confirmant ainsi que la science ouverte offre un avantage pour la science fédérale. Ceci signifie que les scientifiques fédéraux qui publient en libre accès peuvent s’attendre à ce que leurs travaux aient une plus grande incidence. Bien que des progrès aient été réalisés dans la mise en œuvre de la science ouverte, il reste encore beaucoup à faire pour que la science fédérale, les données scientifiques et les scientifiques soient plus accessibles. Les résultats de ce rapport annuel font état de progrès, mais ne permettent pas d’atteindre les objectifs ambitieux fixés dans la Feuille de route pour la science ouverte pour 2022 et les années suivantes. L’engagement et le soutien continus envers science ouverte sont nécessaires pour atteindre ces objectifs.

description: In decentralized machine learning, workers compute model updates on their local data. Because the workers only communicate with few neighbors without central coordination, these updates propagate progressively over the network. This paradigm enables distributed training on networks without all-to-all connectivity, helping to protect data privacy as well as to reduce the communication cost of distributed training in data centers. A key challenge, primarily in decentralized deep learning, remains the handling of differences between the workers' local data distributions. To tackle this challenge, we introduce the RelaySum mechanism for information propagation in decentralized learning. RelaySum uses spanning trees to distribute information exactly uniformly across all workers with finite delays depending on the distance between nodes. In contrast, the typical gossip averaging mechanism only distributes data uniformly asymptotically while using the same communication volume per step as RelaySum. We prove that RelaySGD, based on this mechanism, is independent of data heterogeneity and scales to many workers, enabling highly accurate decentralized deep learning on heterogeneous data.

Mechanisms of diclofop methyl uptake in oat protoplasts (Avena sativa ’Cascade’)
Creators: name: Tritter, Susan
Publisher: name: University of British Columbia
Year: 2010

description: Isolated oat protoplasts ( Avena sativa L. 'Cascade') were used to compare the uptake of the herbicide diclofop methyl (methyl 2-(4-(2,4-diehlorophenoxy)phenoxy)propanoate) and the acid form diclofop (2-(4-(2,4-dichlorophenoxy)phenoxy) propionic acid and to study herbicide uptake as a basis for the 2,4-D-diclofop methyl antagonism. Diclofop methyl was rapidly taken up by protoplasts (≤ 5 seconds) to a constant level which did not change significantly with incubation times up to 1.0 hour. Forty percent of added 14C-diclofop methyl was taken up within 5.0 seconds while diclofop uptake was limited over the same time period. Diclofop methyl uptake was linear with herbicide concentration in the uptake solution up to 50 μM. There was no significant difference between uptake by burst or intact protoplasts preparations. Large accumulations of 14C-diclofop methyl were found in the membrane fractions of the protoplasts. Diclofop methyl uptake appeared to be a passive, non-mediated process in which the herbicide was partitioned into the lipid phase of the protoplast membrane. Diclofop methyl was converted to the acid form in the treatment solution by hydrolase enzymes apparently associated with the external surface of the protoplast plasma membrane. 2,4-D did not affect diclofop methyl or diclofop uptake at concentrations from 10 μM to 2.0 mM nor was the conversion of diclofop methyl to diclofop affected by 2,4-D except at high non-physiological concentrations. Diclofop methyl and diclofop did not adversely affect membrane permeability of the protoplasts at the herbicide concentrations used in these experiments. Protoplast preparations proved to be a useful and simple system to study the uptake and metabolism of herbicides in plants.

description: The crux of single-channel speech separation is how to encode the mixture of signals into such a latent embedding space that the signals from different speakers can be precisely separated. Existing methods for speech separation either transform the speech signals into frequency domain to perform separation or seek to learn a separable embedding space by constructing a latent domain based on convolutional filters. While the latter type of methods learning an embedding space achieves substantial improvement for speech separation, we argue that the embedding space defined by only one latent domain does not suffice to provide a thoroughly separable encoding space for speech separation. In this paper, we propose the Stepwise-Refining Speech Separation Network (SRSSN), which follows a coarse-to-fine separation framework. It first learns a 1-order latent domain to define an encoding space and thereby performs a rough separation in the coarse phase. Then the proposed SRSSN learns a new latent domain along each basis function of the existing latent domain to obtain a high-order latent domain in the refining phase, which enables our model to perform a refining separation to achieve a more precise speech separation. We demonstrate the effectiveness of our SRSSN by conducting extensive experiments, including speech separation in a clean (noise-free) setting on WSJ0-2/3mix datasets as well as in noisy/reverberant settings on WHAM!/WHAMR! datasets. Furthermore, we also perform experiments of speech recognition on separated speech signals by our model to evaluate the performance of speech separation indirectly.

Oxyurella singalensis

description: 38. Oxyurella singalensis (Daday, 1898)
Localities and specimens found: 50 – 2♀, 1♀ ov, 3j; 51 – 3♀, 1♀ ov, 1♀ em, 1j.
Distribution and ecology. Oxyurella singalensis is distributed in the Afrotropical, Oriental and Australian biogeographic regions (Kotov et al. 2013a; Sinev 2017; Lopez et al. 2017). This is one of the most common Oriental species of chydorids (Idris 1983; Michael & Sharma 1988; Sanoamuang 1998; Maiphae et al. 2005, 2008; Tanaka & Ohtaka 2010; Chatterjee et al. 2013; Korovchinsky 2013; Kotov et al. 2013b; Pascual et al. 2014; Ji et al. 2015; Sinev & Yusoff 2015, 2018; Sinev et al. 2015; Sinev 2016; Lopez et al. 2017; Sharma & Sharma 2017; Tiang-nga et al. 2020; Choedchim & Maiphae 2023). It is also well known and widespread in Vietnam (Dang et al. 1980, 2002; Dang & Ho 2001; Sinev & Korovchinsky 2013).
Oxyurella singalensis is a littoral species associated with vegetation. It dwells in bottom sediments and among aquatic vegetation in a wide variety of water bodies, primarily in stagnant ones, but it is also found in moderately flowing habitats (Idris 1983; Sanoamuang 1998; Dang & Ho 2001; Pascual et al. 2014; Sinev et al. 2015; Sinev 2016; Lopez et al. 2017; Choedchim & Maiphae 2023). In our material, the species was rare and was detected only in the rhizosphere of floating plants (see Appendix 1).

description: There are large classes of inflationary models, particularly popular in the context of string theory and brane world approaches to inflation, in which the ratio of linearized tensor to scalar metric fluctuations is very small. In such models, however, gravitational waves produced by scalar modes cannot be neglected. We derive the lower bound on the tensor-to-scalar ratio by considering the back-reaction of the scalar perturbations as a source of gravitational waves. These results show that no cosmological model that is compatible with a metric scalar amplitude of $\approx 10^{-5}$ can have a ratio of the tensor to scalar power spectra less than $\approx 10^{-8}$ at recombination and that higher-order terms leads to logarithmic growth for r during radiation domination. Our lower bound also applies to non-inflationary models which produce an almost scale-invariant spectrum of coherent super-Hubble scale metric fluctuations.

description: Tritoniopsis Eliot 1905
(Figs 3C, 4C, 5C, 6C)
Tritoniopsilla Pruvot-Fol 1933, Mem. L’ Inst. D’ Egypte, 21: 90.
Type species: Tritoniopsis brucei Eliot 1905, by original designation.
Diagnosis: Alternate oral processes. Numerous, fully arborescent gills. Rachidian tooth unicuspid and denticulate, first lateral tooth undifferentiated, few lateral teeth per row.
Morphology: Body slightly broad, length up to 100 mm (Fig. 3C). Oral veil broad, bilobed or entire. Nine to 13 velar processes alternating in size. Fourteen to 20 pairs of arborescent gills, mostly uniform. Ratio jaw/body length: 0.11–0.15. Rachidian tooth unicuspid (Fig. 4C). Central cusp strong, sharp and long; small denticles present in the lower region of the base. Laterals slender, hooked and sometimes denticulate. Small number of lateral teeth (up to ten per half row). Masticatory borders of jaws differentiated or smooth. Cuticular folds absent. ODG complex large (more than two-thirds of total animal length) (Fig. 5C). Gonopore at one-third of body length, furthest from rhinophores. Anus and nephroproct at midbody length or beyond. Female gland mass large (Fig. 6C). Bursa copulatrix pyriform or oval. Penis flagelliform or conical.
Species composition: Tritoniopsis brucei, Tritoniopsis elegans and Tritoniopsis flydis.
Remarks: Apartfromthediagnosticsynapomorphies, Tritoniopsis is characterized by medium-sized species (up to 100 mm) with an elongated ODG complex, and a large female gland mass (Odhner 1936, Er. Marcus and Ev. Marcus 1970). The masticatory border of the jaw is smooth in Tritoniopsis brucei and Tritoniopsis elegans (Eliot 1905, Yonow 2017), and differentiated as comprised of irregular cell-like structures in Tritoniopsis flydis (Er. Marcus and Ev. Marcus 1970). Tritoniopsis was recovered as a sister group to Marianina in our phylogenetic analyses (Table 2). Both genera have unicuspid and denticulate rachidian teeth which are easily distinguished: the unicuspid rachidian of Tritoniopsis is stronger with a few small denticles in the lower region of the base (Fig. 4C), while the unicuspid rachidian of Marianina is narrower and fully denticulate with larger cusps (Odhner 1936).

Second post-Newtonian approximation of Einstein-aether theory

description: In this paper, second post-Newtonian approximation of Einstein-aether theory is obtained by Chandrasekhar's approach. Five parameterized post-Newtonian parameters in first post-Newtonian approximation are presented after a time transformation and they are identical with previous works, in which $γ=1$, $β=1$ and two preferred-frame parameters remain. Meanwhile, in second post-Newtonian approximation, a parameter, which represents third order nonlinearity for gravity, is zero the same as in general relativity. For an application for future deep space laser ranging missions, we reduce the metric coefficients for light propagation in a case of $N$ point masses as a simplified model of the solar system. The resulting light deflection angle in second post-Newtonian approximation poses another constraint on the Einstein-aether theory.

A multiple measurement outcome evaluation of a behaviorally oriented inservice training program
Creators: name: Lee, Douglas Spencer
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the immediate and long term impact of a portable, behaviorally-oriented, in-service training program. The training program consisted of a site visit (pre-test), 5 day workshop (mid-test), 5 follow-up visits, and a termination visit (post-test). The termination visit occurred 6-8 weeks following the last follow-up. Each training program spanned approximately 8-9 months. The training package consisted of lectures, films or video-tapes, demonstrations, role-play, behavioral rehearsal, and homework. Major areas covered during the training were teaching techniques (specifically Discrete Trial Format teaching), program writing, language training, curriculum development, reinforcement principles, maintenance and generalization, behavior management and token economy. The training team was composed of a coordinator, psychologist, teacher and community nurse. Thirty-two direct service staff for severely handicapped clients served as trainees. These trainees were from training programs conducted in four communities in the Province of British Columbia from 1979-1981. Data on three dependent measures plus consumer satisfaction measures were gathered using a pre-mid-post institutional cycle design. The three dependent measures were behavioral terminology, Discrete Trial Format teaching and program writing. Consumer satisfaction data were collected at the completion of the workshop and at the termination visit. For the terminology and Discrete Trial Format teaching measures significant increases were found at mid-test and post-test in the trainees' scores and in the proportion of trainees exceeding pre-established criteria for these measures. No pre-test program writing data were available. There was a significant decrease in the program writing scores from mid to post-test. Consumer satisfaction data was uniformly positive at both measurement periods. The significance of these results are discussed in relation to previous research done in this area. Inferences are made about how factors such as trainee employment contracts, teacher schedules, and reinforcement schedules may have influenced the results. Problems in conducting this type of research under field conditions are identified and potential areas for further research are suggested.

description: The purpose of this document is to show how the AC power balance and flow equations used in power flow and optimal power flow computations can be expressed in terms of complex matrices, and how their first and second derivatives can be computed efficiently using complex sparse matrix manipulations. Similarly, the derivatives of the generalized AC OPF cost function used by MATPOWER and the corresponding OPF Lagrangian function are developed. The relevant code in MATPOWER is based on the formulas found in this note, in which nodal balances are expressed in terms of complex power and voltages are represented in polar coordinates, and in the companion MATPOWER Technical Note 3 and MATPOWER Technical Note 4, which present formulas for variations based on nodal current balances and cartesian coordinate voltages, respectively.

description: We show that a scaling law exists for the near resonant dynamics of cold kicked atoms in the presence of a randomly fluctuating pulse amplitude. Analysis of a quasi-classical phase-space representation of the quantum system with noise allows a new scaling law to be deduced. The scaling law and associated stability are confirmed by comparison with quantum simulations and experimental data.

description: We analyze the behavior of the trace of the resolvent of an elliptic cone differential operator as the spectral parameter tends to infinity. The resolvent splits into two components, one associated with the minimal extension of the operator, and another, of finite rank, depending on the particular choice of domain. We give a full asymptotic expansion of the first component and expand the component of finite rank in the case where the domain is stationary. The results make use of, and develop further, our previous investigations on the analytic and geometric structure of the resolvent. The analysis of nonstationary domains, considerably more intricate, is pursued elsewhere. © 2010 American Mathematical Society.
Channel saturation and conductance quantization in single-atom gold constrictions

description: It is shown that the finite elasticity of atomic-sized gold constrictions allows for a continuous and reversible change in conductance. This is achieved by superposition of atomic-scale or subatomic-scale mechanical oscillations on a steadily retracting/approaching gold tip against a gold substrate. Through these perturbation studies, we report the direct observation of channel saturation and conductance quantization in stable, single-atom gold constrictions. In addition, the origin of peaks in conductance histograms is explained, and the peaks alone are shown to be insufficient in evaluating the stability of atomic configurations. © 2010 The American Physical Society.
An exact particle method for scalar conservation laws and its application to stiff reaction kinetics

description: An "exact" method for scalar one-dimensional hyperbolic conservation laws is presented. The approach is based on the evolution of shock particles, separated by local similarity solutions. The numerical solution is defined everywhere, and is as accurate as the applied ODE solver. Furthermore, the method is extended to stiff balance laws. A special correction approach yields a method that evolves detonation waves at correct velocities, without resolving their internal dynamics. The particle approach is compared to a classical finite volume method in terms of numerical accuracy, both for conservation laws and for an application in reaction kinetics. © 2011 Springer-Verlag Berlin Heidelberg.
