Executing an accurate full-reference metric such as VQM can take minutes in an average computer for just one user. Therefore, it can be unfeasible to analyze all the videos received by users in an IPTV network for example consisting of 10.000 users using a single computer running the VQM metric. One solution can be to use a lightweight no-reference metrics in addition to the full-reference metric

Understanding of recombination and photoconductivity dynamics of photogenerated charge carriers in GaxIn1-xP NWs is essential for their optoelectronic applications. In this letter, we have studied a series of GaxIn1-xP NWs with varied Ga composition. Time-resolved photoinduced luminescence, femtosecond transient absorption, and time-resolved THz transmission measurements were performed to assess r

The worldwide blood shortage has generated demands for alternatives to transfusible human blood. One such important option is based on recombinant hemoglobin-based oxygen carriers (rHBOCs). Most efforts have been focused on various E. coli based production systems. One of the key challenges in these systems is to devise an efficient and economical protein production strategy involving selection of

Lynn Sagan's conjecture (1967) that three of the fundamental organelles observed in eukaryote cells, specifically mitochondria, plastids and flagella were once free-living primitive (prokaryotic) cells was accepted after considerable opposition. Even though the idea was swiftly refuted for the specific case of origins of flagella in eukaryotes, the symbiosis model in general was accepted for decad

In this paper, we introduce a new simple but powerful general technique for the study of edge- and vertex-reinforced processes with super-linear reinforcement, based on the use of order statistics for the number of edge, respectively of vertex, traversals. The technique relies on upper bound estimates for the number of edge traversals, proved in a different context by Cotar and Limic [Ann. Appl. P

A representation of the two-loop contribution to the pion decay constant in SU(3) chiral perturbation theory is presented. The result is analytic up to the contribution of the three (different) mass sunset integrals, for which an expansion in their external momentum has been taken. We also give an analytic expression for the two-loop contribution to the pion mass based on a renormalized representa

In the cloud computing service model, users consume computation resources provided through the Internet, often without any awareness of the cloud service provider that owns and operates the supporting hardware infrastructure. This marks an important change compared to earlier models of computation, for example when such supporting hardware infrastructure was under the control of the user. Given th

In the present study, we applied a regularized inversion method to extract the particle size, magnetic moment and relaxation-time distribution of magnetic nanoparticles from small-angle x-ray scattering (SAXS), DC magnetization (DCM) and AC susceptibility (ACS) measurements. For the measurements the particles were colloidally dispersed in water. At first approximation the particles could be assume

We present a detailed study of open heavy flavor production in high-energy pp collisions at the LHC in the color dipole framework. The transverse momentum distributions of produced b-jets, accounting for the jet energy loss, as well as produced open charm D and bottom B mesons in distinct rapidity intervals relevant for LHC measurements are computed. The dipole model results for the differential b

Stair ascending performance is critical during evacuation from buildings and underground infrastructures. Healthy subjects performed self-paced ascent in three settings: 13 floor building, 31 floor building, 33 m stationary subway escalator. To investigate leg muscle and cardiorespiratory capacities and how they constrain performance, oxygen uptake (VO2), heart rate (HR) and ascending speed were m

This paper describes the properties and performance status of vertical III-V nanowire transistors. The development of key process modules has advanced the vertical fabrication technology and competitive device performance is reported for InAs MOSFETs and TunnelFETs. Besides the benefits in electrostatic control and the ease in integration on Si substrates, the vertical transistors offers a path to

Markstörningar, som stubbskörd och markberedning, leder initialt till minskad koldioxidavgång från marken, visar en serie nya försök. Det är tvärtemot vad man tidigare har antagit. Efter det första året ligger avgången på ungefär samma nivå för störd mark som för ostörd.

Over the last several decades, γ-aminobutyric acid (GABA) has attracted much attention due to its diverse physiological implications in plants, animals, and microorganisms. GABA naturally occurs in plant materials and its concentrations may vary considerably, from traces up to μmol/g (dry basis) depending on plant matrix, germination stage, and processing conditions, among other factors. However,

Departing from previous research on digital action networks, this paper approaches the spread and emotional contagion of digital activism slightly differently, looking for it not necessarily inside the social movement itself, but rather outside it. By questioning the implicit assumption that the spread and emotional contagion of digital activism is contained only in the context of social movements

I fyra försök var utsläppen av de kraftfulla växthusgaserna lustgas och metan ungefär på samma nivå från stubbskördade ytor som från ytor där stubbarna var kvar. Inte heller markberedning gav några signifikanta effekter. De här studierna är de första i världen på det här området, och resultaten måste därför tolkas med viss försiktighet.

We argue that strategic management in general—and capability theory in particular—suffers from problems of infinite regress that can be traced to an unsatisfactory specification of initial conditions. We argue, first, that this has led to an overemphasis on path dependence, experience, and history, without sufficient attention on initial conditions: more proximate, decision-oriented punctuation po
