description: We confirmed the annealing time of Grover's search which is required to obtain desired success probability for quantum annealing by the imaginary-time and the real-time Schrödinger equation with two kinds of schedulings; one linearly decreases the quantum fluctuation and the other tunes the evolution rate of the Hamiltonian based on the adiabatic condition. With linear scheduling, the required annealing time for quantum annealing by the imaginary-time Schrödinger equation is of order $\log N$, which is very different from $O(N)$ required for the quantum annealing by the real-time Schrödinger equation. With the scheduling based on the adiabatic condition, the required annealing time is of order $\sqrt{N}$, which is identical to the annealing time for quantum annealing by the real-time Schrödinger equation. Although the scheduling based on the adiabatic condition is optimal for the quantum annealing by the real-time Schrödinger equation, it is inefficient for the quantum annealing by the imaginary-time Schrödinger equation. This result implies that the optimal scheduling for the quantum annealing by the imaginary-time and the real-time Schrödinger equation is very different, and the efficient scheduling considered with the quantum Monte Carlo methods, which is based on imaginary-time Schrödinger equation, is not necessarily effective to improve the performance of quantum annealing by the real-time Schrödinger equation. We discuss the efficient scheduling for quantum annealing by the imaginary-time Schrödinger equation with respect to the exponential decay of excited states.

description: We construct Spin(p+1,p+1) covariant Dp-brane bound states by using that the potentials in the RR sector of toroidically compactified type II supergravity transform as a chiral spinor of the T-duality group. As an application, we show the invariance of the zero-force condition for a probe D-brane under noncommutative deformations of the background, which gives a holographic proof of the stability of the corresponding field theory ground state under noncommutative deformations. We also identify the Spin(p+1,p+1) transformation laws by examining the covariance of the D-brane Lagrangians.

description: No abstracts are to be cited without prior reference to the author.In June 2006 a survey was conducted to investigate French Eastern English Channel fishers’ observations of the past and current state of the marine ecosystem and their wishes for the future. Twenty-seven semi-directive interviews were carried out among fishers practicing various activities, and two of shellfish farmers. A majority of interviewees mentioned a decrease of the resource in recent years and pointed out the presence of several problems, such as pollution, degradation of the sea floor and harmful impacts of human activities, including fishing. We compared these statements to available scientific information: landings, effort and trawl survey data. The two sources of information agreed generally in terms of direction of changes, but fishers' perceptions were more short term even though most of them had been in the business for several decades.

description: Collision-induced absorption (CIA) from molecular hydrogen is a dominant opacity source in the atmosphere of cool white dwarfs. It results in a significant flux depletion in the near-IR and IR parts of their spectra. Because of the extreme conditions of helium-rich atmospheres (where the density can be as high as a few g/cm$^3$), this opacity source is expected to undergo strong pressure distortion and the currently used opacities have not been validated at such extreme conditions. To check the distortion of the CIA opacity we applied state-of-the-art ab initio methods of computational quantum chemistry to simulate the CIA opacity at high densities. The results show that the CIA profiles are significantly distorted above densities of $0.1\,{\rm g/cm}^3$ in a way that is not captured by the existing models. The roto-translational band is enhanced and shifted to higher frequencies as an effect of the decrease of the interatomic separation of the H$_2$ molecule. The vibrational band is blueward shifted and split into $Q_R$ and $Q_P$ branches, separated by a pronounced interference dip. Its intensity is also substantially reduced. The distortions result in a shift of the maximum of the absorption from $2.3\,μ{\rm m}$ to $3-7 μ{\rm m}$, which could potentially explain the spectra of some very cool, helium-rich white dwarfs.

A molecular characterization of meningeal inflammation in progressive MS brain
Creators: name: Fuentes Font, Laura
Publisher: name: Imperial College London

description: Introduction: The presence of lymphoid-like immune cell aggregates in the leptomeninges is suggested to promote damage to the cerebral cortex and play a role in accumulating disability in multiple sclerosis (MS). Methods: Cryosections were cut from five cortical blocks per case from 55 SPMS, 12 PPMS and 14 control post-mortem brains. Meningeal tissue was dissected and RNA extracted. Affymetrix HTA 2.0 GeneChips were used to obtain the meningeal transcriptome and gene expression determined using R package Limma. Differentially expressed genes with FC>2 and FDR>0.05 were used to perform gene set enrichment analysis using WebGestalt and gene networks constructed using R package WGCNA. Results: When comparing controls with highly inflamed SPMS cases, alterations were mainly found in expression of homing chemokines and immune receptors and that enhance B cell survival, co-stimulation, proliferation and antibody and IFNγ production (SLAMF7, CXCR4, GZMK, CD27). Gene network analysis revealed networks associated with immune response, specially highlighting processes such as response to virus, chemokine signalling and antigen presentation. Functional pathway analysis for these network modules identified significant involvement in the MS meninges, of pathways associated with cell adhesion, TCR and BCR co-stimulation and activation, Th17, Th1/Th2 cell differentiation, haematopoietic and lymphoid organ development. The most highly altered genes were loaded into Ingenuity Pathway Analysis, yielding results that suggest a dysregulation of pathways critical for B-T cell interaction, disrupting antigen presentation and its subsequent outcomes. A panel of 55 inflammatory genes was chosen for validation of the microarray data using TaqMan OpenArrays. Highly significant, strong and moderately strong, correlations were found between the TaqMan and Affymetrix data for most individual genes, providing robustness to our meningeal transcriptomics data. Remarkably, we found a very different signature when analysing PPMS data pointing towards an involvement of the innate immune system, featuring alterations in the signalling axis involving chemokine receptors CXCR1, CXCR2, and their ligands CXCL8 and CXCL7. Besides, preliminary functional enrichment analysis mainly highlights the pathways granulocyte activation, platelet 2 degranulation, neutrophil mediated immunity, processes that did not appear as enriched in SPMS data. Altogether, suggesting that the immune response might be differently built or initiated in PPMS compared to SPMS. Conclusions: We have identified molecular cues that are likely to play a major role in mediating meningeal inflammation in MS, which suggest a dysregulation of pathways that are critical for B cell trafficking and recruitment into the CNS

description: We conducted an event study to examine the effect of E. coli recalls on prices in the vertically connected U.S. beef industry. Our findings show that the resulting price changes of beef products vary across stages in the U.S. beef industry and that the prices of disaggregated beef products are more vulnerable to E. coli recalls than the prices of aggregated products. This suggests that downstream agents transacting specific ground beef products may be more adversely affected by E. coli recalls than upstream agents trading live animals.

description: Dit is het derde en laatste deel in de reeks boeken dat over de Noctuidae-verzameling van de Franse entomoloog en musicoloog Jacques Plante handelt. Zoals in de vorige twee delen is de tekst erg summier gehouden en ligt het grootste belang in de afbeeldingen van soorten die men in de meest Europese literatuur niet terug vindt. In het eerste deel uit deze reeks wordt Jacques Plante voorgesteld met de nadruk op zijn entomologische acties, vooral zijn eigen entomologische reizen naar landen waar maar weinig hedendaagse entomologen zouden naartoe reizen: Algerije, West Bengalen, Kashmir, de Verenigde Arabische Emiraten, Spanje, Israël, Ladakh, Marokko, Nepal, Pakistan, de Centraal-Afrikaanse Republiek, Taiwan en Turkije. Daarnaast ontving hij vele collega-entomologen die voor hem veel materiaal aanbrachten uit Nepal, Tibet, de Himalayas, Sulawesi en Borneo, Brazilië, de Nieuwe Hebriden, en vooral Madagaskar. De motten uit dit laatste land vormen wellicht de tweede grootste verzameling ter wereld na die in het Musée d'Histoire naturelle de Paris. Veel van het verzamelde materiaal kwam terecht bij andere verzamelaars of in verscheidene musea. De Noctuidae echter, waarin Jacques Plante vooral gespecialiseerd was, werd aangeworven door het Musée d'histoire naturelle de Genève. Daar werd de hele verzameling herwerkt, vooral door de broers Gábor en László Ronkay, en het resultaat daarvan werd o.l.v. Bernard Landry in dit boek en de twee vorige delen samengevat.

description: U.S. consumers see retail beef products with “no added hormones” (NAH) labels. However, similar labels appear on pork and chicken products, even though hormone use in their production is prohibited. This study assesses consumer perceptions of hormone use in different livestock species. Using choice experiment data, we then examine the impact of these perceptions on preferences for unlabeled meat products and willingness to pay for NAH-labeled meat products. Results suggest that consumer perceptions of hormone use in production are incorrect. Further, perceptions influence consumer preferences and willingness to pay for unlabeled products versus those with NAH labels.

description: Extraction of the nucleon's strange form factors from experimental data requires a quantitative understanding of the unavoidable contamination from isospin violation. A number of authors have addressed this issue during the past decade, and their work is reviewed here. The predictions from early models are largely consistent with recent results that rely as much as possible on input from QCD symmetries and related experimental data. The resulting bounds on isospin violation are sufficiently precise to be of value to on-going experimental and theoretical studies of the nucleon's strange form factors.

description: We consider several variants of the classical Cops and Robbers game. We treat the version where the robber can move R≥1 edges at a time, establishing a general upper bound of , where α = 1 + 1/R, thus generalizing the best known upper bound for the classical case R = 1 due to Lu and Peng, and Scott and Sudakov. We also show that in this case, the cop number of an n-vertex graph can be as large as n1 − 1/(R − 2) for finite R≥5, but linear in n if R is infinite. For R = 1, we study the directed graph version of the problem, and show that the cop number of any strongly connected digraph on n vertices is O(n(loglogn)2/logn). Our approach is based on expansion.

We first describe a classification of all the possible realisations of branes of M and type II theories as topological solitons of a brane-antibrane system. We then present a description of type IIB NS-NS p-branes in terms of topological solitons in systems of spacetime-filling NS9, anti-NS9 pairs and discuss the implications of these constructions in the description of BPS and non-BPS states in the strongly coupled Heterotic SO(32) theory. We finally present briefly the construction of a conjectured spacetime-filling non-BPS M10-brane, starting point for a brane descent construction of the branes of M-theory.

description: Using the framework of cumulative prospect theory (CPT), we investigate consumers’ decision to participate in community-supported agriculture (CSA) under risk and uncertainty. We analyze discrete choice experiment data using a CPT framework that allows for flexible reference points and individual preference heterogeneity. Comparison between model specifications suggests that the CPT model with the control of all risk parameters generates better goodness of fit than the expected utility model. Market sensitivity analysis further indicates that, while CSA operators benefit from transferring production risk partially to consumers, the level of transferred risk has a great impact on market share.

In the calculation, we consider matters with and without neutrino trapping as the target. We have found that the difference between the two mean free paths depends not only on the neutrino energy, but also on the matter density as well as matter constituents. Compared to the nucleon weak magnetism, the neutrino electromagnetic properties are found to have negligible effects on this difference.

Creators: name: Kupschus, Sven
Publisher: name: ASC 2007 - Theme session O

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.UK Fisheries for bass do not fit neatly into the ‘standard’ ICES framework for assessments and advice for a number of reasons. The fisheries are mostly inshore, operated from commercial / semi-commercial small boats that are not obliged to provide trip or even area based landings information. The degree to which bass are targeted depends strongly on the relative availability of bass and other target species. A substantial recreational fishery contributes significantly to mortality, yet little or nothing is known about its absolute magnitude or its effects on stocks. Survey information for bass is limited to estuarine recruitment surveys, which are spatially restricted, and there are no fisheries independent measures of adult abundance. In other words, an age-based VPA type approach is unlikely to be helpful in managing this fishery. Or is it? The stock synthesis assessment approach has been able to shed considerable light on some of the most important issues for managers of bass stocks. First and foremost, the stocks are expanding under increasing exploitation levels, suggesting that they are exploited sustainably. Estimated selection patterns for the fleets are robust to uncertainty in F, so that these can be used to explore different exploitation scenarios. Fishing mortality is formally linked to effort. Recruitment estimates from the surveys were independently shown to be efficient predictors of future recruitment despite their caveats. Therefore the measures for effectively managing and monitoring a fishery are available. What the assessments can’t do is provide short-term forecasts for setting TACs, determine PA reference points for assessing stock status or divide the catch fairly between different sectors. These are the things that managers have become to see as the wholly grail of management under the CFP. It is unclear to what degree the bass management success is due to luck, design, biology or plain necessity, but it is clear that bass management would have been much poorer in the absence of detailed biological knowledge and the standard ICES approach of annual TAC setting would not have been practical given the availability of data. This implies that a more individual approach to stock management with considerations of data availability, species biology, fishers’ behaviour and clear management objectives are more important to fisheries management than precise numbers-at-age tables or use of specific assessment models. This presentation discusses the link that the assessment makes between the available bass data and management needs and emphasises the importance of getting this right. This paper does not present any new results or even radically new ideas. It represents a synopsis of the differences between bass assessments and the ICES assessment paradigm
Time-delocalized quantum subsystems and operations: on the existence of processes with indefinite causal structure in quantum mechanics
Creators: name: Oreshkov, Ognyan
Publisher: name: arXiv
Year: 2018
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: It has been shown that it is theoretically possible for there to exist higher-order quantum processes in which the operations performed by separate parties cannot be ascribed a definite causal order. Some of these processes are believed to have a physical realization in standard quantum mechanics via coherent control of the times of the operations. A prominent example is the quantum SWITCH, which was recently demonstrated experimentally. However, the interpretation of such experiments as realizations of a process with indefinite causal structure as opposed to some form of simulation of such a process has remained controversial. Where exactly are the local operations of the parties in such an experiment? On what spaces do they act given that their times are indefinite? Can we probe them directly rather than assume what they ought to be based on heuristic considerations? How can we reconcile the claim that these operations really take place, each once as required, with the fact that the structure of the presumed process implies that they cannot be part of any acyclic circuit? Here, I offer a precise answer to these questions: the input and output systems of the operations in such a process are generally nontrivial subsystems of Hilbert spaces that are tensor products of Hilbert spaces associated with systems at different times---a fact that is directly experimentally verifiable. With respect to these time-delocalized subsystems, the structure of the process is one of a circuit with a causal cycle. I also identify a whole class of isometric processes, of which the quantum SWITCH is a special case, that admit a physical realization on time-delocalized subsystems. These results unveil a novel structure within quantum mechanics, which may have important implications for physics and information processing.

description: Lobe dynamics and escape from a potential well are general frameworks introduced to study phase space transport in chaotic dynamical systems. While the former approach studies how regions of phase space are transported by reducing the flow to a two-dimensional map, the latter approach studies the phase space structures that lead to critical events by crossing periodic orbit around saddles. Both of these frameworks require computation with curves represented by millions of points-computing intersection points between these curves and area bounded by the segments of these curves-for quantifying the transport and escape rate. We present a theory for computing these intersection points and the area bounded between the segments of these curves based on a classification of the intersection points using equivalence class. We also present an alternate theory for curves with nontransverse intersections and a method to increase the density of points on the curves for locating the intersection points accurately.The numerical implementation of the theory presented herein is available as an open source software called Lober. We used this package to demonstrate the application of the theory to lobe dynamics that arises in fluid mechanics, and rate of escape from a potential well that arises in ship dynamics.

description: We examine the excitation of oscillations in the magnetic network of the Sun through the footpoint motion of photospheric magnetic flux tubes located in intergranular lanes. The motion is derived from a time series of high-resolution G band and continuum filtergrams using an object-tracking technique. We model the response of the flux tube to the footpoint motion in terms of the Klein-Gordon equation, which is solved analytically as an initial value problem for transverse (kink) waves. We compute the wave energy flux in upward propagating transverse waves. In general we find that the injection of energy into the chromosphere occurs in short-duration pulses, which would lead to a time variability in chromospheric emission that is incompatible with observations. Therefore, we consider the effects of turbulent convective flows on flux tubes in intergranular lanes. The turbulent flows are simulated by adding high-frequency motions (periods 5-50 s) with an amplitude of 1 km s^{-1}. The latter are simulated by adding random velocity fluctuations to the observationally determined velocities. In this case we find that the energy flux is much less intermittent and can in principle carry adequate energy for chromospheric heating.

description: No abstracts are to be cited without prior reference to the author.The North Sea Regional Advisory Council (NSRAC) is the main forum through which fisheries interests are involved in marine spatial planning (MSP) on the North Sea. The NSRAC is a relatively new and fragile forum involving various stakeholders. MSP confronts this group with a series of broader issues such as inter alia wind farms, transportation, and marine protected areas. The spatial focus involves both a reduction and a multiplication of the levels of geographical scale at which information for management must be resolved. The ongoing development of these institutions provides lessons about facilitating the evolution of cross-scale institutional linkages that strengthen adaptive, eco-system based management.

description: Given a discrete random walk on a finite graph G, the vacant set and vacant net are, respectively, the sets of vertices and edges which remain unvisited by the walk at a given step t.%These sets induce subgraphs of the underlying graph. Let Γ(t) be the subgraph of Ginduced by the vacant set of the walk at step t. Similarly, let Γˆ(t) be the subgraph of G induced by the edges of the vacant net. For random r-regular graphs Gr, it was previously established that for a simple random walk, the graph Γ(t) of the vacant set undergoes a phase transition in the sense of the phase transition on Erd\H{os}-Renyi graphs Gn,p. Thus, for r≥3 there is an explicit value t∗=t∗(r) of the walk, such that for t≤(1−ϵ)t∗, Γ(t) has a unique giant component, plus components of size O(logn), whereas for t≥(1+ϵ)t∗ all the components of Γ(t) are of size O(logn). We establish the threshold value tˆ for a phase transition in the graph Γˆ(t) of the vacant net of a simple random walk on a random r-regular graph. We obtain the corresponding threshold results for the vacant set and vacant net of two modified random walks. These are a non-backtracking random walk, and, for r even, a random walk which chooses unvisited edges whenever available. This allows a direct comparison of thresholds between simple and modified walks on random r-regular graphs. The main findings are the following: As r increases the threshold for the vacant set converges to nlogr in all three walks. For the vacant net, the threshold converges to rn/2logn for both the simple random walk and non-backtracking random walk. When r≥4 is even, the threshold for the vacant net of the unvisited edge process converges to rn/2, which is also the vertex cover time of the process.

description: Motivated by recent prototypes of engineered atomic spin devices, we study a fully connected system of $N$ spins $1/2$, modeled by the Lipkin-Meshkov-Glick (LMG) model of a collective spin $s=N/2$ in the presence of Markovian dissipation processes. We determine and classify the different phases of the dissipative LMG model with Markovian dissipation, including the properties of the steady-state and the dynamic behavior in the asymptotic long-time regime. Employing variational methods and a systematic approach based on the Holstein-Primakoff mapping, we determine the phase diagram and the spectral and steady-state properties of the Liouvillian by studying both the infinite-$s$ limit and $1/s$ corrections. Our approach reveals the existence of different kinds of dynamical phases and phase transitions, multi-stability and regions where the dynamics is recurrent. We provide a classification of critical and non-critical Liouvillians according to their spectral and steady-state properties.

description: We evaluate the impact of access to credit on rural households’ annual income using an endogenous switching regression approach, an increasingly popular method of tackling the selection bias issue in impact analyses. Using a large survey of rural households in eastern India, we find that access to credit is strongly associated with rural households’ socioeconomic and demographic characteristics. Additionally, access to credit increases rural households’ economic well-being; nonborrower rural households would benefit the most from access to credit. Access to credit affects recipients heterogeneously, implying that credit policies should be adaptable to different rural household groups.
Exponential Hierarchies from Anderson Localization in Theory Space

description: We present a new mechanism for generating exponential hierarchies in four-dimensional field theories inspired by Anderson localization in one dimension, exploiting an analogy between the localization of electron energy eigenstates along a one-dimensional disordered wire and the localization of mass eigenstates along a local "theory space" with random mass parameters. Mass eigenstates are localized even at arbitrarily weak disorder, with exponentially suppressed couplings to sites in the theory space. The mechanism is quite general and may be used to exponentially localize fields of any spin. We apply the localization mechanism to two hierarchies in Standard Model parameters --- the smallness of neutrino masses and the ordering of quark masses --- and comment on possible relevance to the electroweak hierarchy problem. This raises the compelling possibility that some of the large hierarchies observed in and beyond the Standard Model may result from disorder, rather than order.

Utility Maximization Trading Two Futures with Transaction Cost

description: An agent invests in two types of futures contracts, whose prices are possibly correlated arithmetic Brownian motions, and invests in a money market account with a constant interest rate. The agent pays a transaction cost for trading in futures proportional to the size of the trade. She also receives utility from consumption. The agent maximizes expected infinite-horizon discounted utility from consumption. We determine the first two terms in the asymptotic expansion of the value function in the transaction cost parameter around the known value function for the case of zero transaction cost. The method of solution when the futures are uncorrelated follows a method used previously to obtain the analogous result for one risky asset. However, when the futures are correlated, a new methodology must be developed. It is suspected in this case that the value function is not twice continuously differentiable, and this prevents application of the former methodology

description: We develop a four-sector (labor-intensive agriculture, capital-intensive agriculture, service & construction, and manufacturing) general-equilibrium model of North American countries to analyze the effects of tighter U.S. immigration policies. Results show that these policies erode the comparative advantage of U.S. labor-intensive agriculture, causing U.S. production and exports to fall and other countries to expand their exports to the United States. In Mexico, low-skilled labor demand in labor-intensive agriculture increases as production rises. The effectiveness of U.S. tighter immigration policies depends on the substitutability between U.S. domestic and undocumented workers. Immigration policies exacerbate the wedge between Mexican low-skilled wage rate and the undocumented wage rate, intensifying the underlying cause for unauthorized entry.
Supergravity and D-branes Wrapping Supersymmetric 3-Cycles

description: We construct dual supergravity descriptions of D3-branes wrapping associative 3-cycles $L$. We analyse the conditions for having five-dimensional background solutions of the form $AdS_2 \times L$ and show that they require $L$ to be of constant negative curvature type. This provides $AdS_2$ background solutions when $L$ is the hyperbolic space $H^3$ or its quotients by subgroups of its isometry group. We construct a regular numerical solution interpolating between $AdS_5$ in the UV and $AdS_2 \times H^3$ in the IR. The IR fixed point exists at the ``intersection'' of the Coulomb and Higgs branches. We analyse the singular supergravity solutions which correspond to moving into the Higgs and the Coulomb branches. For negative constant curvature spaces the singularity is of a ``good'' type in the Higgs branch and of a ``bad'' type in the Coulomb branch. For positive constant curvature spaces such as $S^3$ the singularity is of a ``bad'' type in both the Higgs and the Coulomb branches. We discuss the meaning of these results.

Symplectic deformations of Floer homology and non-contractible periodic orbits in twisted disc bundles

description: In this paper we establish the existence of periodic orbits belonging to any $σ$-atoroidal free homotopy class for Hamiltonian systems in the twisted disc bundle, provided that the compactly supported time-dependent Hamiltonian function is sufficiently large over the zero section and the magnitude of the weakly exact $2$-form $σ$ admitting a primitive with at most linear growth on the universal cover is sufficiently small. The proof relies on showing the invariance of Floer homology under symplectic deformations and on the computation of Floer homology for the cotangent bundle endowed with its canonical symplectic form. As a consequence, we also prove that, for any nontrivial atoroidal free homotopy class and any positive finite interval, if the magnitude of a magnetic field admitting a primitive with at most linear growth on the universal cover is sufficiently small, the twisted geodesic flow associated to the magnetic field has a periodic orbit on almost every energy level in the given interval whose projection to the underlying manifold represents the given free homotopy class. This application is carried out by showing the finiteness of the restricted Biran-Polterovich-Salamon capacity.

The role of local and global strangeness neutrality at the inhomogeneous freeze-out in relativistic heavy ion collisions

description: The decoupling surface in relativistic heavy-ion collisions may not be homogeneous. Rather, inhomogeneities should form when a rapid transition from high to low entropy density occurs. We analyze the hadron "chemistry" from high-energy heavy-ion reactions for the presence of such density inhomogeneities. We show that due to the non-linear dependence of the particle densities on the temperature and baryon-chemical potential such inhomogeneities should be visible even in the integrated, inclusive abundances. We analyze experimental data from Pb+Pb collisions at CERN-SPS and Au+Au collisions at BNL-RHIC to determine the amplitude of inhomogeneities and the role of local and global strangeness neutrality.

description: Upcoming 5G-based communication networks will be confronted with huge increases in the amount of transmitted sensor data related to massive deployments of static and mobile Internet of Things (IoT) systems. Cars acting as mobile sensors will become important data sources for cloud-based applications like predictive maintenance and dynamic traffic forecast. Due to the limitation of available communication resources, it is expected that the grows in Machine-Type Communication (MTC) will cause severe interference with Human-to-human (H2H) communication. Consequently, more efficient transmission methods are highly required. In this paper, we present a probabilistic scheme for efficient transmission of vehicular sensor data which leverages favorable channel conditions and avoids transmissions when they are expected to be highly resource-consuming. Multiple variants of the proposed scheme are evaluated in comprehensive realworld experiments. Through machine learning based combination of multiple context metrics, the proposed scheme is able to achieve up to 164% higher average data rate values for sensor applications with soft deadline requirements compared to regular periodic transmission.
