description: Recurrent neural networks (RNNs) are a class of neural networks that have emerged from the paradigm of artificial intelligence and has enabled lots of interesting advances in the field of natural language processing. Interestingly, these architectures were shown to be powerful ansatze to approximate the ground state of quantum systems. Here, we build over the results of [Phys. Rev. Research 2, 023358 (2020)] and construct a more powerful RNN wave function ansatz in two dimensions. We use symmetry and annealing to obtain accurate estimates of ground state energies of the two-dimensional (2D) Heisenberg model, on the square lattice and on the triangular lattice. We show that our method is superior to Density Matrix Renormalisation Group (DMRG) for system sizes larger than or equal to $14 \times 14$ on the triangular lattice.

description: We present a method of obtaining the quasi exact solution of the Jahn Teller systems in the framework of osp(2,2) superalgebra. The hamiltonian have been solved in the Bargmann-Fock space by obtaining an expression as linear and bilinear combinations of the generators of osp(2,2). In particulare, we have discussed quasi exact solvability of Exe Jahn-Teller Hamiltonian.
Effectiveness of a school-based physical activity intervention for increasing bone strength in children : Action Schools! BC
Creators: name: Macdonald, Heather McGillvray
Publisher: name: University of British Columbia
Year: 2010

description: Introduction: Osteoporosis and related fracture are significant societal health burdens. Physical activity during childhood can result in significant bone health benefits, which may reduce the risk for osteoporosis later in life. Aim: The primary aim was to evaluate the effectiveness of a school-based physical activity model, Action Schools! BC (AS! BC), for enhancing bone mass and strength in boys and girls using novel bone imaging technologies. Methods: Design and participants: This was a 16-month cluster randomized, controlled, school-based intervention. Ten schools were randomized to Intervention (INT, 7 schools) or Control (CON, 3 schools). The bone-loading component of AS! BC was a daily, high-impact jumping program (Bounce at the Bell) plus 15 minutes/day of classroom physical activity. Participants were 514 children aged 9-11 years at baseline. Bone Measurements: Tibial bone strength was assessed with peripheral quantitative computed tomography. Dual energy x-ray absorptiometry and hip structure analysis were used to assess femoral neck bone mineral content (BMC) and bone strength, respectively. Results: Part 1: Cross-sectional Comparisons. In pre- and early pubertal boys tibial bone strength was 5-15% greater than in pre- and early pubertal girls. After adjusting for tibial length, muscle cross-sectional area was the primary explanatory variable of bone strength in both sexes. Part 2: 16-Month Change - Tibial Bone Strength. Intervention boys (n = 147) tended to have greater gains in tibial bone strength than CON boys (n = 64); however, the intervention effect was only significant for prepubertal boys at the distal tibia. Action Schools! BC was not effective for increasing tibial bone strength in girls (n = 137 INT, 65 CON). Part 3: 16-Month Change - Femoral Neck Bone Mass and Strength. Intervention girls tended to have greater gains in femoral neck bone strength and BMC than CON girls; however, the difference in change between groups was not significant. Action Schools! BC was not effective for increasing femoral neck bone mass or strength in boys. Summary: Skeletal adaptations to the AS! BC intervention were sex-, maturity- and site-specific. Action Schools! BC offers promise as a simple and inexpensive strategy for increasing bone mass and strength in boys and girls.
Expert perspectives on achieving global sustainability with targeted transformational change

Publisher: name: The Australian National University

description: To address the increasingly acute global environmental and social problems, transformational change is required to the prevailing socioeconomic systems. Some interpret this to mean that economic growth must become "green", while others question if "post-growth" approaches are needed instead. In this dissertation, I examine what future pathways sustainability scholars think different country income groups should follow for global sustainability to be achieved. To evaluate expert perspectives, I organized a global expert survey (n=461) and used statistical modelling to help explain the scholars' views. After the survey, I focused on transformational change in the context of a specific high-income country, Finland, by organising a Delphi-workshop with Finnish sustainability and post-growth experts (n=14), applying a backcasting method. The thesis findings imply support for targeted transformational change. Most sustainability scholars were in favour of post-growth pathways for high- and upper-middle-income countries while green growth was favoured for low- and lower-middle-income countries. As support for post-growth increased from the 2020s to 2030s, support for green growth decreased in all contexts. I found substantial variation in the scholars' opinions regarding the future of economic growth. The expert workshop corroborated the survey results and produced a new vision of a post-growth Finland, evaluating obstacles to change and potential actions that could facilitate the needed transformation. The panel recognised Finland's structural dependence on economic growth as a key issue. This "societal addiction" to growth is obstructing rich countries from following the post-growth pathways preferred by sustainability scholars. My results demonstrate that there now exists a high demand for post-growth solutions. Scholars should respond to this demand by focusing more on detailing post-growth solutions and less on criticizing the status-quo. Particularly in high-income countries, the main focus of scholars and decision makers alike should now turn towards overcoming the prevailing societal growth addictions. I conclude that while the societal dependence on nature cannot be overcome, the dependence on growth can be. This could help societies achieve important environmental goals and sustainable wellbeing, in time.

description: Graph neural networks (GNNs) are emerging in chemical engineering for the end-to-end learning of physicochemical properties based on molecular graphs. A key element of GNNs is the pooling function which combines atom feature vectors into molecular fingerprints. Most previous works use a standard pooling function to predict a variety of properties. However, unsuitable pooling functions can lead to unphysical GNNs that poorly generalize. We compare and select meaningful GNN pooling methods based on physical knowledge about the learned properties. The impact of physical pooling functions is demonstrated with molecular properties calculated from quantum mechanical computations. We also compare our results to the recent set2set pooling approach. We recommend using sum pooling for the prediction of properties that depend on molecular size and compare pooling functions for properties that are molecular size-independent. Overall, we show that the use of physical pooling functions significantly enhances generalization.

description: Face reenactment aims to animate a source face image to a different pose and expression provided by a driving image. Existing approaches are either designed for a specific identity, or suffer from the identity preservation problem in the one-shot or few-shot scenarios. In this paper, we introduce a method for one-shot face reenactment, which uses the reconstructed 3D meshes (i.e., the source mesh and driving mesh) as guidance to learn the optical flow needed for the reenacted face synthesis. Technically, we explicitly exclude the driving face's identity information in the reconstructed driving mesh. In this way, our network can focus on the motion estimation for the source face without the interference of driving face shape. We propose a motion net to learn the face motion, which is an asymmetric autoencoder. The encoder is a graph convolutional network (GCN) that learns a latent motion vector from the meshes, and the decoder serves to produce an optical flow image from the latent vector with CNNs. Compared to previous methods using sparse keypoints to guide the optical flow learning, our motion net learns the optical flow directly from 3D dense meshes, which provide the detailed shape and pose information for the optical flow, so it can achieve more accurate expression and pose on the reenacted face. Extensive experiments show that our method can generate high-quality results and outperforms state-of-the-art methods in both qualitative and quantitative comparisons.

description: The final merger of a pair of massive black holes in a galactic nucleus is compelled by gravitational radiation. Gravitational waves from the mergers of black holes of masses (10^5-10^7)(1+z)^{-1} Msun at redshifts of 1-20 will be readily detectable by the Laser Interferometer Space Antenna (LISA), but an electromagnetic afterglow would be helpful in pinpointing the source and its redshift. Long before the merger, the binary "hollows out" any surrounding gas and shrinks slowly compared to the viscous timescale of a circumbinary disk. The inner gas disk is truncated at the radius where gravitational torque from the binary balances the viscous torque, and accretion onto the black holes is diminished. Initially, the inner truncation radius is able to follow the shrinking binary inward. But eventually the gravitational radiation timescale becomes shorter than the viscous timescale in the disk, leading to a merged black hole surrounded by a hollow disk of gas. We show that the subsequent viscous evolution of the hollow, radiation-pressure dominated disk will create a ~10^{43.5}(M/10^6Msun) ergs s^{-1} X-ray source on a timescale \~7(1+z)(M/10^6Msun)^{1.32} yr. This justifies follow-up monitoring of gravitational wave events with next-generation X-ray observatories. Analysis of the detailed light curve of these afterglows will yield new insights into the subtle physics of accretion onto massive black holes.

Head injuries in the rural setting : what is the role of the Canadian CT head guidelines
Creators: name: Von Der Porten, Fern
Publisher: name: University of British Columbia
Year: 2011

description: The Canadian CT head rule is a valuable tool in the clinical assessment of head injuries. It risk stratifies head injured patients, identifying the ones that will require neurological intervention and the ones having clinically important brain injuries (sensitivities 100% and 98.6%, respectively). This standardized approach to head injuries may challenge the rural practitioner without access to CT scan. The Whistler Health Care Center (WHCC) is a Diagnostic and Treatment Centre seeing approximately 23,000 patients annually, many of them trauma patients with a high acuity level. There is no CT scanner on site. This provides a unique setting to study head injuries: a large number of head-injured patients with limited diagnostic tools, like many other rural facilities in Canada. It was hypothesized that following the Canadian CT Head Guidelines at the Whistler Health Care Center would have increased the number of scans performed. This study is a retrospective chart review of all patients triaged with head injury, or trauma, to the WHCC in 2004. Canadian CT head guidelines were applied to all charts, and were risk stratified according to the guidelines. 516 charts were reviewed, 305 of which were excluded (5 GCS<13, 1 pregnant, 5 seizures prior to assessment, 56 no amnesia, LOC or disorientation, 38 follow-ups, 174 age < 16 yrs, 22 not seen by MD , 1 acute neurological deficit, 1 unstable vitals, 1 depressed skull fracture, 1 anticoagulant use), and 211 were included. Of the 211 included charts, 51 had CT indicated, and only 4 of these were transferred to a health care facility with CT scan available. A further 9 patients, without meeting the CT criteria were also transferred. The WHCC has a high number of head injuries annually. When the Canadian CT head guidelines are applied, a greater number of scans are indicated. Some scans, however, in the minor risk group, could have been avoided. When the CT head guidelines are applied to the rural setting without diagnostic CT, patients with high-risk criteria should all be transferred. A prospective study in a similar setting is recommended to determine the management of moderate risk patients.

description: The celebrated S-Lemma was originally proposed to ensure the existence of a quadratic Lyapunov function in the Lur'e problem of absolute stability. A quadratic Lyapunov function is, however, nothing else than a squared Euclidean norm on the state space (that is, a norm induced by an inner product). A natural question arises as to whether squared non-Euclidean norms $V(x)=\|x\|^2$ may serve as Lyapunov functions in stability problems. This paper presents a novel non-polynomial S-Lemma that leads to constructive criteria for the existence of such functions defined by weighted $\ell_p$ norms. Our generalized S-Lemma leads to new absolute stability and absolute contractivity criteria for Lur'e-type systems, including, for example, a new simple proof of the Aizerman and Kalman conjectures for positive Lur'e systems.

description: The problem of bound entanglement detection is a challenging aspect of quantum information theory for higher dimensional systems. Here, we propose an indecomposable positive map for two-qutrit systems, which is shown to generate a class of positive partial transposed (PPT) states. A corresponding witness operator is constructed and shown to be weakly optimal and locally implementable. Further, we perform a structural physical approximation of the indecomposable map to make it a completely positive one, and find a new PPT entangled state which is not detectable by certain other well-known entanglement detection criteria.

description: Proteins are subject to aging in the form of spontaneous, nonenzymatic post-translational modifications (PTMs). One such PTM is the formation of the β-linked isomer l-isoaspartic acid (isoAsp) from aspartic acid (Asp) or asparagine residues, which tends to occur in long-lived proteins. Histones can exhibit half-lives on the order of 100 days, and unsurprisingly, isoAsp formation has been observed in nearly every histone family. Delineating the molecular consequences of isoAsp formation in histones is challenging due to the multitude of processes that occur on such time scales. To isolate the effects of a specific isoAsp modification thus necessitates precise in vitro characterization with well-defined substrates. Here, we adapt a protein semisynthesis approach to generate full-length variants of histone H4 in which the canonical Asp at position 24 is replaced by its isoAsp isomer (H4isoD24). This variant was incorporated into chromatin templates, and the resulting constructs were used to interrogate key parameters of chromatin integrity and maintenance in vitro: compaction, nucleosome remodeling, and methylation of H4 lysine 20 (H4K20). Remarkably, despite its disruptive changes to the backbone's spacing and direction, isoD24 did not dramatically disrupt Mg2+-mediated chromatin self-association or nucleosome repositioning by the remodeler Chd1. In contrast, H4isoD24 significantly inhibited both Set8- and Suv4-20h1-catalyzed methylation at H4K20. These results suggest that H4isoD24 gives rise to a complex reorganization of the chromatin functional landscape, in which macroscopic processes show robustness and local mechanisms exhibit vulnerability to the presence of this mark.

description: In this paper, we introduce Linear Logic with a nondeterministic facility, which has a self-dual additive connective. In the system the proof net technology is available in a natural way. The important point is that nondeterminism in the system is expressed by the process of normalization, not by proof search. Moreover we can incorporate the system into Light Linear Logic and Elementary Linear Logic developed by J.-Y.Girard recently: Nondeterministic Light Linear Logic and Nondeterministic Elementary Linear Logic are defined in a very natural way.

description: Online Gaussian processes (GPs), typically used for learning models from time-series data, are more flexible and robust than offline GPs. Both local and sparse approximations of GPs can efficiently learn complex models online. Yet, these approaches assume that all signals are relatively accurate and that all data are available for learning without misleading data. Besides, the online learning capacity of GPs is limited for high-dimension problems and long-term tasks in practice. This paper proposes a sparse online GP (SOGP) with a forgetting mechanism to forget distant model information at a specific rate. The proposed approach combines two general data deletion schemes for the basis vector set of SOGP: The position information-based scheme and the oldest points-based scheme. We apply our approach to learn the inverse dynamics of a collaborative robot with 7 degrees of freedom under a two-segment trajectory tracking problem with task switching. Both simulations and experiments have shown that the proposed approach achieves better tracking accuracy and predictive smoothness compared with the two general data deletion schemes.

description: We constructed the new classes of exact multi-lump solutions of KP-1 and KP-2 versions of KP equations with integrable boundary condition $u_{y}\big|_{y=0}=0$ by the use of $\overline\partial$-dressing method of Zakharov and Manakov and derived general determinant formula for such solutions. We demonstrated how reality and boundary conditions for the field $u$ in the framework of $\overline\partial$-dressing method can be exactly satisfied. Here we present explicit examples of two-lump solutions with integrable boundary as nonlinear superpositions of two more simpler "deformed" one-lump solutions: the fulfillment of boundary condition leads to formation of certain eigenmodes of the field $u(x,y,t)$ in semiplane $y\geq 0$ as analogs of standing waves on string with fixed end points.

The approximation is applied to the description of the nematic phase of linear uniaxial dimers interacting via a standard molecular pair-potential. Transition temperatures, order parameters and pair correlation averages are calculated for different spacer lengths. The results readily reproduce the experimentally observed trends of phase transition thermodynamics and of dipolar correlations deduced from dielectric studies.

description: We studied the behavior of nonlinear spinor field within the scope of a static cylindrically symmetric space-time. It is found that the energy-momentum tensor (EMT) of the spinor field in this case possesses nontrivial non-diagonal components. The presence of non-diagonal components of the EMT imposes three-way restrictions wither on the space-time geometry or on the components of the spinor field or on both. It should be noted that analogical situation occurs in cosmology when nonlinear spinor field is exploited as a source of gravitational field given by Bianchi type-I cosmological model.

ASEAN's new role in the Asia Pacific Region: can it be a driving force of wider regional economic cooperation?
Creators: name: Okamoto, Jiro
Publisher: name: Australia-Japan Research Centre
Year: 1995

description: This paper analyses how ASEAN members (Indonesia, Malaysia, Philippines, Singapore, Thailand, Brunei) have been responding to the changing world economic environment, and how ASEAN, as a regional organisation, has been changing its priorities to reflect members' adjustments to the international environment. In its early phase, ASEAN was simply a group of neighbouring countries without coordinated external policy positions. However, it is now becoming a subsystem in international relations and able to put a collective point of view. The members of ASEAN have realised that it is more effective to voluntarily coordinate their positions in international forums and negotiations. The ASEAN Free Trade Area ( AFT A) agreement is analysed as a new type of A SEAN cooperation and a step towards broader cooperation in the Asia Pacific region. Whether ASEAN can and should be a driving force for broader economic cooperation in the Asia Pacific region is discussed. An ASEAN initiative in this regard, namely the Asia Pacific Economic Cooperation (APEC) process, will be a test of unity for ASEAN itself. Also, the desirability of creating a middle-power coalition, consisting of ASEAN members, Australia, New Zealand and Korea, is considered. Such a coalition would be more beneficial for ASEAN, as well as for other countries in the region, than the proposed framework of the East Asian Economic Caucus (EAEC). This is a revised version of a paper presented at an international symposium on ' Multi-layered Regional Cooperation in Southeast Asia after the Cold War' , organised by the Institute of Developing Economies , 9-10 November 1994, Tokyo_, Japan .

description: In 2014 the European Commission implemented the European Circular Economy Package to promote a shift of Europe¿s economy towards a circular economic system. In order to successfully achieve this change, a well founded knowledge about the availability of resources, the flow of substances and the markets of recovered raw materials gained by recycling has to be obtained. Within the course of this thesis, questions arising related to international trade and domestic market for steel, aluminium and copper scrap are discussed. Therefore, the export and import flows and specific prices from the metals between the EU-28 and the world from the year 2000 to 2014 are examined. Additionally, the structure of the traded quantities and relations between different variables as well as possible tendencies are explained by statistical methods and analysis of time series. Moreover, the issue of Endof- Life Vehicles with unknown whereabouts and their impact on the interior scrap market of the EU is mentioned. Summarizing the outcome of the discussion, export quantities for steel and aluminium scrap follow a positive linear trend, while the underlying function of copper scrap export is polynomial with its vertex in the year 2011. All import quantities behaved similarly but mirrored. A visual analysis of the data series for prices suggest a correlation between import and export figures for all three scrap metals. For steel, as example, this presumption is supported by a linear regression. Besides, the specific import prices are almost over the whole observed time range significantly higher than the import levels. This alteration was assumed to be triggered by different composition of material flows, and for steel scrap the evidence is provided. Furthermore, following recommendations for the legislative body of the EU are expressed. First, the recycling industry shall be pushed to ensure not only high recycling rates, but also the sorted disposal of scrap according to their special attributes shall be promoted. Second, the possible impact of an interior oversupply of scrap within the Single Market upon domestic prices has to be considered. Hence, imposing tariffs on scrap exports or subsidizing the secondary raw metal production industry offer possible regulative measures. Furthermore, directives addressed to the problems related to the unknown whereabouts of End-of-Live Vehicles have to be adjusted accordingly, as there is still a substantial loss experienced by the interior scrap market of the EU-28.

description: SFILES is a text-based notation for chemical process flowsheets. It was originally proposed by d'Anterroches (2006) who was inspired by the text-based SMILES notation for molecules. The text-based format has several advantages compared to flowsheet images regarding the storage format, computational accessibility, and eventually for data analysis and processing. However, the original SFILES version cannot describe essential flowsheet configurations unambiguously, such as the distinction between top and bottom products. Neither is it capable of describing the control structure required for the safe and reliable operation of chemical processes. Also, there is no publicly available software for decoding or encoding chemical process topologies to SFILES. We propose the SFILES 2.0 with a complete description of the extended notation and naming conventions. Additionally, we provide open-source software for the automated conversion between flowsheet graphs and SFILES 2.0 strings. This way, we hope to encourage researchers and engineers to publish their flowsheet topologies as SFILES 2.0 strings. The ultimate goal is to set the standards for creating a FAIR database of chemical process flowsheets, which would be of great value for future data analysis and processing.

description: The Comprehensive Nuclear Test Ban Treaty (CTBT) is an international agreement that bans nuclear weapon tests. Since its adoption in 1997, the Preparatory Commission has worked relentlessly to establish the International Monitoring System (IMS), a global network of monitoring stations capable of detecting signs of nuclear explosions. The 337 IMS facilities deploy four detection technologies: seismic, infrasound, hydroacoustic and radionuclide. While monitoring the atmosphere, the Earth crust and the oceans for verification purposes, the stations also detect and record signals generated by a long list of natural and anthropogenic occurrences, such as severe storms, earthquakes and civil nuclear activities. This background noise, from which eventual signs of nuclear tests must be discerned, carries an intrinsic value that could be exploited in several ways. The purpose of this work is to determine what this additional value is and how it could be used by relevant stakeholders. This will be achieved by identifying research fields, studies, civil applications and policies that could be supported by the data collected by the IMS, and by exploring how a wider accessibility to the data could be granted. Results will show the relevance of the data in understanding the impact of global warming, improving civil aviation safety and supporting several State Parties policies, such those related to disaster mitigation, civil use of nuclear energy and climate change. The above findings will serve as a base to argue for the establishment of National and Regional Data Centers and the creation of a portal to CTBTO archive of raw data and bulletins.

description: We propose a novel method enabling autocompletion of chemical flowsheets. This idea is inspired by the autocompletion of text. We represent flowsheets as strings using the text-based SFILES 2.0 notation and learn the grammatical structure of the SFILES 2.0 language and common patterns in flowsheets using a transformer-based language model. We pre-train our model on synthetically generated flowsheets to learn the flowsheet language grammar. Then, we fine-tune our model in a transfer learning step on real flowsheet topologies. Finally, we use the trained model for causal language modeling to autocomplete flowsheets. Eventually, the proposed method can provide chemical engineers with recommendations during interactive flowsheet synthesis. The results demonstrate a high potential of this approach for future AI-assisted process synthesis.

description: Ferromagnetic single electron transistors with Al islands and orthogonal ferromagnetic leads (Co) are fabricated using ebeam lithography followed by shadow evaporation techniques. I-V characteristics exhibit typical single electron tunneling effects. Transport measurements performed in external magnetic field show that, when the two ferromagnetic leads are in antiparallel configuration, spin imbalance leads to a suppression of superconductivity.

description: We give the comparisons between the chiral SU(3) quark model and the extended chiral SU(3) quark model. The results show that the phase shifts of NN scattering are very similar. However, the short range mechanisms of nucleon-nucleon interaction are totally different. In the chiral SU(3) quark model, the short range interaction is dominantly from OGE, and in the extended chiral SU(3) quark model, it is dominantly from vector meson exchanges.

Weak Typed Boehm Theorem on IMLL

description: In the Boehm theorem workshop on Crete island, Zoran Petric called Statman's ``Typical Ambiguity theorem'' typed Boehm theorem. Moreover, he gave a new proof of the theorem based on set-theoretical models of the simply typed lambda calculus. In this paper, we study the linear version of the typed Boehm theorem on a fragment of Intuitionistic Linear Logic. We show that in the multiplicative fragment of intuitionistic linear logic without the multiplicative unit 1 (for short IMLL) weak typed Boehm theorem holds. The system IMLL exactly corresponds to the linear lambda calculus without exponentials, additives and logical constants. The system IMLL also exactly corresponds to the free symmetric monoidal closed category without the unit object. As far as we know, our separation result is the first one with regard to these systems in a purely syntactical manner.

description: La pêche à pied est une activité récréative importante pour les zones littorales, notamment de l'Ouest de la France, mais mal connue. L'analyse des réactions des pêcheurs à pied face aux risques encourus par des changements de qualité des eaux permet de fonder une estimation de la valeur de ce loisir et de chiffrer le préjudice qu'ils peuvent subir lors d'une dégradation du milieu. L'application de la méthode d'évaluation contingente, avec les coûts de déplacement comme véhicule de paiement, fournit une mesure pertinente de cette valeur. L'analyse permet également de s'interroger sur le comportement du public vis-à-vis de l'information sur ces risques ainsi que sur la pertinence de la politique publique en matière d'information.
Politique de la concurrence et secteur agro-alimentaire dans l’Union européenne

description: Le secteur agro-alimentaire dans l'Union européenne (UE) se caractérise par la coexistence d'entreprises agricoles de taille relativement modeste et de firmes de grande taille pour l'industrie en amont (industrie fournissant les intrants) et en aval (industrie de transformation, grande distribution). Cette taille modeste des exploitations agricoles par rapport à leur aval et à leur amont peut être défavorable à un partage équilibré de la valeur ajoutée entre les différents maillons des filières agro-alimentaires, dans la mesure où ce partage dépend des pouvoirs de marché et de négociation des uns et des autres. L'Unité mixte de recherche Economie publique INRA-INAPG a analysé comment la politique de la concurrence s'exerce dans le secteur agro-alimentaire européen. Cet article de synthèse a pour objectif de présenter les grandes lignes de cette politique pour les marchés de l'agro-alimentaire dans l'UE. Les principes économiques et juridiques sont brièvement rappelés, avant d'étudier les principales décisions françaises et européennes.

description: Electronic parametric instabilities of an ultrarelativistic circularly polarized laser pulse propagating in underdense plasmas are studied by numerically solving the dispersion relation which includes the effect of the radiation reaction force in laser-driven plasma dynamics. Emphasis is placed on studying the different modes in the laser-plasma system and identifying the absolute and convective nature of the unstable modes in a parameter map spanned by the normalized laser vector potential and the plasma density. Implications for the ultraintense laser-plasma experiments are pointed out.

description: Using the data acquired in the Time To Spill (TTS) mode for long gamma-ray bursts (GRBs) collected by the Burst and Transient Source Experiment on board the Compton Gamma Ray Observatory (BATSE/CGRO), we have carefully measured spectral lags in time between the low (25-55 keV) and high (110-320 keV) energy bands of individual pulses contained in 64 multi-peak GRBs. We find that the temporal lead by higher-energy gamma-ray photons (i.e., positive lags) is the norm in this selected sample set of long GRBs. While relatively few in number, some pulses of several long GRBs do show negative lags. This distribution of spectral lags in long GRBs is in contrast to that in short GRBs. This apparent difference poses challenges and constraints on the physical mechanism(s) of producing long and short GRBs. The relation between the pulse peak count rates and the spectral lags is also examined. Observationally, there seems to be no clear evidence for systematic spectral lag-luminosity connection for pulses within a given long GRB.

description: Chronic physical activity has been shown to ameliorate various aspects of human physiology, while specific training can directly influence structural changes. It remains unknown i f chronic exercise influences upper extremity lymphatic function in females; thus, the purpose of this cross-sectional study was to compare different exercise stresses on lymphatic function in ten upper body trained females (mean (SD): age= 26.9 (SD 4.4) yrs; ht= 165.0 (SD 11.2) cm; wt= 62.1 (SD 11.8) kg; VO2 = 35.0 (SD 3.2) ml•kg[superscript omitted]-min[superscript omitted]) with ten untrained females (age= 31.0 yrs (SD 6.0); ht= 168.1 (SD 6.5); wt= 69.5 (SD 14.7) kg; V02= 22.2 (SD 4.8) ml•kg[superscript omitted]-min[superscript omitted]). Participants underwent a maximal upper body aerobic test on an arm crank ergometer before undergoing three randomly assigned lymphatic stress tests. Lymphoscintigraphy was used to quantify lymphatic function. [superscript omitted]Tc-antimony colloid was injected into the third web space of each hand followed by 1 minute spot views taken with a γ-radiation camera. Axillary acquisitions occurred at 18 (SD 5) and 64 minutes. The maximal stress test required individuals to repeat their initial maximal exercise test and then be imaged every 10 minutes until 60 minutes was reached. The submaximal stress test involved arm cranking for 2.5 minutes at 0.6 W-kg[superscript omitted] followed by 2.5 minutes of rest, repeated for 60 minutes. The final stress test was a 60 minute seated resting session. The amounts cleared at the hand (AC) and axillary uptake (Ax) were determined. Four 2X3 ANOVAs were used to test for statistical significance between the two groups and three lymphatic stress tests. Only Ax post maximal exercise was significantly different between trained and untrained, p=0.009. All other measures of lymphatic function between groups were similar. Exercise had a significant impact on lymphatic function: maximal AC was significantly higher at 10 minutes (p=0.000) while submaximal AC was significantly higher at 60 minutes, (p=0.000). Compared to rest, exercise Ax was significantly greater (p=0.000) but the exercise stress, (maximal or submaximal), Ax at 64 minutes did not significantly differ (p=0.426). This study demonstrates no significant difference between upper body trained and untrained females while exercise stress significantly increased Ax and AC.

description: Due to the appearance of uncontrollable events in discrete event systems, one may wish to replace the behavior leading to the uncontrollability of pre-specified language by some quite similar one. To capture this similarity, we introduce metric to traditional supervisory control theory and generalize the concept of original controllability to $\ld$-controllability, where $\ld$ indicates the similarity degree of two languages. A necessary and sufficient condition for a language to be $\ld$-controllable is provided. We then examine some properties of $\ld$-controllable languages and present an approach to optimizing a realization.
