description: Natural products from plants are an alternative resource in the search for anti-cancer drugs and can have a direct impact on eliminating cancer cells and also reduce cancer side effects. Recently, we have isolated a few flavonoid quercetin and cynaroside from leaf of cynara scolymus L and artocarpus incisa L in Vietnam, with cytotoxic activity relatively strong in Hela cancer cells. The flavonoid compound is a search target, research and development of anti-cancer agents in clinical use. To clarify the important nature of the activity, the subject QSAR studies on cancer Hela cell line use the multiple linear regression (MLR) gradually, partial least square regression (PLS) and artificial neural network. The MLR and PLS models showed good correlation values of R2 = 0.938, Rpred2 = 0.903, and R2 = 0.943, Rpred2 = 0.912, respectively. The MLR model shows the level of importance of atomic charge descriptors. Also, artificial neural network architecture I(6)-HL(4)-O(1) is built with RMSE = 0.00345, R2 = 0.993, Rpred2 = 0.971 using the atomic charge descriptors selected in the MLR model such as neurons of input layer and the anti-cancer activity such as neuron of output layer. The anti-cancer activities of the flavonoids and isoflavonoids in the test group and compounds quercetin and cynaroside isolated from cynara scolymus L and artocarpus incisa L are compared with experimental data and those from references.

description: Axion-Like Particles (ALPs) are predicted by several Beyond the Standard Model theories, in particular, string theory. In the presence of an external magnetic field perpendicular to the direction of propagation, ALPs can couple to photons. Therefore, if an X-ray source is viewed through a magnetised plasma, such as a luminous quasar in a galaxy cluster, we may expect spectral distortions that are well described by photon-ALP oscillations. We present a $571 \ \mathrm{ks}$ combined High and Low Energy Transmission Grating (HETG/LETG) Chandra observation of the powerful radio-quiet quasar H1821+643, hosted by a cool-core cluster at redshift $0.3$. The spectrum is well described by a double power-law continuum and broad$+$narrow iron line emission typical of type-1 Active Galactic Nuclei (AGN), with remaining spectral features $< 2.5\%$. Using a cell-based approach to describe the turbulent cluster magnetic field, we compare our spectrum with photon-ALP mixing curves for 500 field realisations assuming that the thermal-to-magnetic pressure ratio remains constant up to the virial radius. At $99.7\%$ credibility and taking $β= 100$, we exclude all couplings $g_\mathrm{aγ} > 6.3 \times 10^{-13} \ {\mathrm{GeV}}^{-1}$ for most ALP masses $< 10^{-12} \ \mathrm{eV}$. Our results are moderately more sensitive to constraining ALPs than the best previous result from Chandra observations of the Perseus cluster, albeit with a less constrained field model. We reflect on the promising future of ALP studies with bright AGN embedded in rich clusters, especially with the upcoming Athena mission.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A photon exhibits a tiny anomalous magnetic moment $μ_γ$ due to its interaction with an external constant magnetic field in vacuum through the virtual electron-positron background. It is paramagnetic ($μ_γ>0$) in the whole region of transparency, i.e. below the first threshold energy for pair creation and has a maximum near this threshold. The photon magnetic moment is different for eigenmodes polarized along and perpendicular to the magnetic field. Explicit expressions are given for $μ_γ$ for the cases of photon energies smaller and closer to the first pair creation threshold. The region beyond the first threshold is briefly discussed.

description: Peptide-like bond molecules, which can take part to the formation of proteins in a primitive Earth environment, have been detected up to now only towards a few sources. We present a study of HNCO, HC(O)NH$_{2}$, CH$_{3}$NCO, CH$_{3}$C(O)NH$_{2}$, CH$_{3}$NHCHO, CH$_{3}$CH$_{2}$NCO, NH$_{2}$C(O)NH$_{2}$, NH$_{2}$C(O)CN, and HOCH$_{2}$C(O)NH$_{2}$ towards the hot core G31.41+0.31. We have used the spectrum obtained from the ALMA 3mm spectral survey GUAPOS, with an angular resolution of 1.2"$\times$1.2" ($\sim$4500 au), to derive column densities of all the molecular species, together with other 0.2"$\times$0.2" ($\sim$750 au) ALMA observations to study the morphology of HNCO, HC(O)NH$_{2}$ and CH$_{3}$C(O)NH$_{2}$. We have detected HNCO, HC(O)NH$_{2}$, CH$_{3}$NCO, CH$_{3}$C(O)NH$_{2}$, and CH$_{3}$NHCHO, for the first time all together outside the Galactic center. We have obtained molecular fractional abundances with respect to H$_{2}$ from 10$^{-7}$ down to a few 10$^{-9}$ and with respect to CH$_{3}$OH from 10$^{-3}$ to $\sim$4$\times$10$^{-2}$. From the comparison with other sources, we find that regions in an earlier stage of evolution, such as pre-stellar cores, show abundances at least two orders of magnitude lower than those in hot cores, hot corinos or shocked regions. Moreover, molecular abundance ratios towards different sources are found to be consistent between them within $\sim$1 order of magnitude, regardless of the physical properties (e.g. different masses and luminosities), or the source position throughout the Galaxy. New correlations between pairs of molecular abundances have also been found. These results suggest that all these species are formed on grain surfaces in early evolutionary stages of molecular clouds, and that they are subsequently released back to the gas-phase through thermal desorption or shock-triggered desorption.

description: The Square Kilometer Array (SKA) is expected to detect high-redshift galaxies with star formation rates (SFRs) up to two orders of magnitude lower than Herschel surveys and will thus boost the ability of radio astronomy to study extragalactic sources. The tight infrared-radio correlation offers the possibility of using radio emission as a dust-unobscured star formation diagnostic. However, the physics governing the link between radio emission and star formation is poorly understood, and recent studies have pointed to differences in the exact calibration required when radio is to be used as a star formation tracer. We improve the calibration of the relation of the local radio luminosity--SFR and to test whether there are nonlinearities in it. We used a sample of Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) sources and investigated their radio luminosity, which was derived using the NRAO VLA Sky Survey (NVSS) and Faint Images of the Radio Sky at Twenty-cm (FIRST) maps. We stacked the bins of infrared luminosity and SFR and accounted for bins with no detections in the stacked images using survival analysis fitting. This approach was tested using Monte Carlo simulations. After removing sources from the sample that have excess radio emission, which is indicative of nuclear radio activity, we found no deviations from linearity of the mean relations between radio luminosity and either SFR or infrared luminosity. We analyzed the link between radio emission and SFR or infrared luminosity using a local sample of star-forming galaxies without evidence of nuclear radio activity and found no deviations from linearity, although our data are also consistent with the small nonlinearity reported by some recent analyses. The normalizations of these relations are intermediate between those reported by earlier works.

description: A way to increase the Scanning Thermal Microscope (SThM) sensitivity in the harmonic 3w mode is to heat the probe with an AC current sufficiently high to generate a coupling between the AC and the DC signals. We detail in this paper how to properly take into account this coupling with a Wollaston-probe SThM. We also show how to link correctly the thermal conductivity to the thermal conductance measured by the SThM.

description: Based on recent developments, in this letter we study the one parameter deformation of 2+1 dimensional gauge theories with scale invariance and N = 8 supersymmetry, which is expected to be the field theory living on a stack of M2 branes. The deformed gauge theory is defined by a Lagrangian and is based on an infinite set of novel 3-algebras constructed by relaxing the assumption that the invariant metric is positive definite. Under the Higgs mechanism, we can obtain the D-branes world volume theory in the presence of background fluxes.

description: The present study deals with a non-native amino acid, cis-4-hydroxy-d-proline (CHDP) using density functional theory at B3LYP/6-31+G(d,p) level. The potential energy surface scan reveals the global minimum structure of CHDP along with two potential conformers. Highest occupied molecular orbital, lowest unoccupied molecular orbital, and molecular electrostatic potential surfaces are used to explain the chemical reactivity of title molecule. The atomic charge analysis has been carried out using Mulliken and natural population schemes. The equilibrium geometry of CHDP dimer has been obtained and inter-molecular interactions are explored using QTAIM and Natural bonding orbital analyses. Vibrational spectroscopic analysis has been performed on CHDP monomer and dimer at the same level of theory. Assignments to all vibrational modes up to 400 cm−1 have been offered along with their potential energy distribution to the maximum possible accuracy. The calculated frequencies are scaled by an equation, rather than by a constant factor and then compared with experimental FT-IR frequencies obtained by KBr disc and Nujol mull techniques. A number of electronic and thermodynamic parameters have also been evaluated for CHDP monomer and dimer.
Operatorial formulation of the ghost rotationally-invariant slave-Boson theory

description: We propose an operatorially-exact formalism for describing the equilibrium and quantum-dynamical properties of many-electron systems interacting locally on a lattice, called "ghost rotationally-invariant slave-Boson theory" (g-RISB). We demonstrate that our theoretical framework reduces to the recently-developed ghost Gutzwiller approximation (g-GA) at the mean-field level. Furthermore, we introduce the time-dependent mean-field g-RISB action, generalizing the time-dependent GA theory. Since the g-RISB is based on exact reformulation of the many-body problem, it may pave the way to the development of practical implementations for adding systematically quantum-fluctuation corrections towards the exact solution, in arbitrary dimension.

Type species
Calodactylus tibialis Blanchard, 1850 (designation: monotypy).
Diagnosis
Prosternum with an anterior longitudinal carina; protibia with two teeth and with a spur; meso- and metatibiae medially enlarged (Fig. 7 E); meso- and metatarsal claws simple; male ventrite VI with two parallel and setose carina (Fig. 7 B).
Remarks
The genera Calodactylus and Dasyus LePeletier de Saint-Fargeau & Audinet-Serville, 1828 are similar to each other. They can be distinguished by enlargements of the meso- and metatibiae, Calodactylus have a medial enlargement whereas Dasyus have medial and distal areas of the same width. An evident characteristic of these genera is the simple meso- and metatarsal claws, which also occurs in male Pectinosoma Arrow,1913 and some species of Ancistrosoma, Barybas, Ceraspis and Faula.

Inverting geometric transitions: explicit Calabi-Yau metrics for the Maldacena-Nunez solutions

Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Explicit Calabi-Yau metrics are derived that are argued to map to the Maldacena-Nuñez AdS solutions of M-theory and IIB under geometric transitions. In each case the metrics are singular where a H^2 Kähler two-cycle degenerates but are otherwise smooth. They are derived as the most general Calabi-Yau solutions of an ansatz for the supergravity description of branes wrapped on Kähler two-cycles. The ansatz is inspired by re-writing the AdS solutions, and the structure defined by half their Killing spinors, in this form. The world-volume theories of fractional branes wrapped at the singularities of these metrics are proposed as the duals of the AdS solutions. The existence of supergravity solutions interpolating between the $AdS$ and Calabi-Yau metrics is conjectured and their boundary conditions briefly discussed.

Canadian Agri-Food Export Opportunities in a Covid-19 World
Creators: name: Yeung, May
name: Kerr, William
Publisher: name: The School of Public Policy Publications
Year: 2021

description: As with the wider Canadian economy, the Covid-19 pandemic has represented an unprecedented shock to agri-food supply chains. Given the importance of Canadian agri-food exports, it is vital that supply chains rebound from the shock and disruptions are minimal. If this occurs, they should be able to respond to opportunities created by the supply chains of international competitors having to deal with Covid-19 in export markets. The demand for food is expected to increase in step with the forecast rise in global population to over 9 billion by 2050. In the next decade alone, total food use for cereals is forecast to grow by 1.2 per cent annually for cereals, 1.7 per cent for animal products and 1.9 per cent for pulses/roots and tubers. Agricultural production to be used as food, feed and in industrial applications will increase by 15 per cent in the next decade (OECD/FAO 2019). Canadian agri-food supply chains are well positioned to meet these future needs so long as they can maintain their resiliency. While the Covid-19 pandemic has not yet run its full course, it is already clear that Canadian agri-food supply chains, both those involved in provisioning the domestic market and those serving export destinations, have proved to be resilient in the face of the pandemic’s shocks and are rapidly returning to the high levels of efficiency they possessed prior to Covid-19. In the domestic market, while there were short run disruptions for some products, there were always sufficient substitutes on the shelves such that there was no threat to food security. As incomes fell, there have been increased calls on foodbanks but these are problems with the wherewithal to purchase, not food availability. Domestic supply chains proved themselves to be robust in dealing with major shocks including the shift to food consumed at home. The international supply chains for agri-food products also proved very resilient and are now well positioned to take advantage of opportunities. Some other countries’ supply chains have not proved as resilient or have suffered from government policy interventions. A number of Canada’s major competitors have imposed export bans, creating market opportunities that Canada could fill. Other competitors have been slower to deal with illness in their workforces. In some importing markets, their domestic supply chains are struggling, creating opportunities for imports from Canada. Due to projected global population growth, the increasing international market for major Canadian agricultural products such as wheat, beef and pork, and canola, are lucrative targets for Canada’s economic recovery and growth. Canada’s future success, however, depends on its agri-food supply chains not being encumbered by reactive regulations that reduce their efficiency, and by supportive policies that ensure producers in the supply chain weather the short-term pain from the Covid-19 crisis.

Evaluation of outcomes for cardiac arrest patients treated by Provincial Ambulance Service personnel in the Lower Mainland of British Columbia

Year: 2010

description: Information was collected in an eight and a half month prospective study about 358 recent cardiac disease-related cardiac arrest cases which were attended by personnel from the Provincial Ambulance Service in the Lower Mainland of British Columbia. When possible, advanced life support personnel (EMA Ills), regular ambulance attendants (EMA Ms) and Fire Department staff are dispatched to cardiac arrest calls. At the time of this study some areas in the region did not have advanced life support coverage, and some cardiac arrest calls occurred while the EMA Ills were already engaged with another case. Such calls, attended by EMA lis, but not by EMA Ills, served as the comparison group for paramedic performance in this study. Patient outcomes were compared at admission to hospital and at discharge from hospital for the group of patients treated by EMA Ms and the group of patients treated by EMA Ills, or by a combination of EMA Ills and EMA Ms. Strongly significant differences in initial outcome (hospital admission) were found between the two patient groups, with EMA IM patients faring better (p.=0.002). Marginally significant differences in final outcome (discharge alive) between the two patient groups were found, with the EMA III group again doing better (p.=0.10). Whether or not the receiving hospital had a coronary care unit was not associated with a difference in initial (p.=0.45) or final outcome (p.=1.0) for the entire group of patients in the study. Short time in arrest without CPR was associated with better initial outcome (p.=0.00), and with better final outcome (p.=0.01) for all patients. in the study, as was short time to definitive care (initial outcome p.=0.001; final outcome p.=0.03). EMA II patients had a better chance of survival when they arrested during attendance by EMA lis than they did when they were found in arrest. This study suggests that significantly more cardiac arrest victims reach hospital alive, and more survive to be discharged alive from hospital, when their prehospital treatment is provided by advanced life support personnel than when it is provided by regular ambulance personnel.

We define two kinds of transforms for such a surface, which produce the so-called left/right polar surfaces and the adjoint surfaces. These new surfaces are again conformal Willmore surfaces. For them holds interesting duality theorem. As an application spacelike Willmore 2-spheres are classified. Finally we construct a family of homogeneous spacelike Willmore tori.

Matching of correlators in AdS_3/CFT_2

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Recently exact agreement has been found between three-point correlators of chiral operators computed in string theory on AdS_3 x S^3 x T^4 with NS-NS flux and those computed in the symmetric orbifold CFT. However, it has also been shown that these correlators disagree with those computed in supergravity, under any identification of single particle operators which respects the symmetries. In this note we resolve this disagreement: the key point is that mixings with multi-particle operators are not suppressed even at large N in extremal correlators. Allowing for such mixings, orbifold/string theory operators and supergravity operators can be matched such that both non-extremal and extremal three point functions agree, giving further evidence for the non-renormalization of the chiral ring.

description: The electrochemical oxidation of carbenicillin disodium salt (CDS) at gold electrode has been investigated for the first time using cyclic, linear sweep, and differential pulse voltammetric techniques. The dependence of the current on pH, concentration, and scan rate were investigated to optimize the experimental conditions for the determination of carbenicillin. The anodic peak was characterized and process was adsorption-controlled. The number of electrons transferred in the oxidation was calculated. A differential pulse voltammetry method with good precision and accuracy was developed for the determination of carbenicillin. The anodic peak current varied linearly with carbenicillin concentration in the range 1.0 × 10−4 M to 5.0 × 10−6 M with a limit of detection (LOD) of 6.859 × 10−7 M and limit of quantification (LOQ) of 2.286 × 10−6 M. This method can be employed in clinical analysis, quality control, and routine determination of drugs in pharmaceutical analysis.

description: Systems of systems (SoS) are a hot topic in our "fully connected global world". Our aim is not to provide another definition of what SoS are, but rather to focus on the adequacy of reusing standard system architecting techniques within this approach in order to improve performance, fault detection and safety issues in large-scale coupled systems that definitely qualify as SoS, whatever the definition is. A key issue will be to secure the availability of the services provided by the SoS despite the evolution of the various systems composing the SoS. We will also tackle contracting issues and responsibility transfers, as they should be addressed to ensure the expected behavior of the SoS whilst the various independently contracted systems evolve asynchronously.

description: The present study describes chemical composition, antifungal activities, antioxidant assays and total phenolic content of essential oil and different extracts from leaves of Alpinia malaccensis. Sixty-eight components were identified by gas chromatography and gas chromatography–mass spectrometry with camphor (15.2%) and eucalyptol (10.2%) as the main component. The essential oil was found to possess remarkable fungicidal action against tested pathogens like Colletotricum falcatum, Rhizoctonia solani, Sclerotinia sclerotium and Sclerotium rolfsii followed by different extracts obtained in solvents like methanol, dichloromethane and hexane, respectively. The essential oil showed higher phenolic contents (69.51 μg/ml) than the extracts. The antioxidant assay of essential oil and extracts by different methods revealed good-to-moderate antioxidant potential with different IC50 values viz. (174.16–230.01 μg/ml) for Fe3+ reducing power, (111.74–158.23 μg/ml) for Fe2+ metal-chelating ability, (82.64–96.66 μg/ml) for DPPH, (94.28–189.41 μg/ml) for OH radical, (76.96–135.63 μg/ml), for NO radical and (107.30–199.75 μg/ml) in superoxide anion scavenging activities, respectively, compared to the standard antioxidants. Based on obtained results, the herb A. malaccensis can be a good source to develop a safe and sustainable natural antioxidant.
A New World Sheet Field Theory

Year: 2008

description: A second quantized field theory on the world sheet is developed for summing planar graphs of the phi^3 theory. This is in contrast to the earlier work, which was based on first quantization. The ground state of the model is investigated with the help of a variational ansatz. In complete agreement with standard perturbation theory, the infinities encountered in carrying out this calculation can be eliminated by the renormalization of the parameters of the model. We also find that, as in the earlier work, in the ground state, graphs form a dense network (condensate) on the world sheet.

Soluble Models of Strongly Interacting Ultracold Gas Mixtures in Tight Waveguides

description: A generalized Fermi-Bose mapping method is used to determine the exact ground states of several models of mixtures of strongly interacting ultracold gases in tight waveguides, which are generalizations of the Tonks-Girardeau (TG) gas (1D Bose gas with point hard cores) and fermionic Tonks-Girardeau (FTG) gas (1D spin-aligned Fermi gas with infinitely strong zero-range attractions). We detail the case of a Bose-Fermi mixture with TG boson-boson (BB) and boson-fermion (BF) interactions. Exact results are given for density profiles in a harmonic trap, single-particle density matrices, momentum distributions, and density-density correlations. Since the ground state is highly degenerate, we analyze the splitting of the ground manifold for large but finite BB and BF repulsions.

Strategies of cereal rust management : redesign of an agro-ecosystem to alter its stability properties
Creators: name: Fleming, Richard Arthur
Publisher: name: University of British Columbia
Year: 2010

description: A major concern in contemporary ecology has been the failure of management in many economically and socially important renewable resource systems. In spite of efforts to the contrary, management has often witnessed the evolution of such systems into behavior patterns almost diametrically opposed to their original objectives. Actually, it is management intervention which often seems to have initiated this evolution by disturbing the system's stability properties. This study shows how an alternative approach which emphasizes system redesign may alleviate the .problem of changing stability properties in some relatively simple and well studied ecosystems: the cereal rusts and the crops which they attack. The plant disease epidemiological literature records a number, of ideas about the behavior and management of cereal rust systems. Many of these ideas have been neither adequately field tested nor developed in a coherent analytic framework. In this study mathematical methods are used to determine the logical consequences of some of these hypotheses. The analysis suggests that cereal rust systems might indeed be redesigned to help management meet its objectives. Four alternative and mutually compatible potential strategies for achieving this goal are considered: (1) using natural enemies to delay disease onset, (2) using multilines or variety mixtures to inhibit plant to plant dispersal, (3) changing field geometry to increase dispersal wastage, and (4) employing polygenic resistance to slow the growth rate of the best adapted races. The research and development required to implement any of these strategies is briefly discussed. Recommendations for future work and comments on the promise of plant epidemiology as an area for ecological research are provided.
Localized Lna Cooling in Vacuum

description: In the Square Kilometre Array (SKA) telescope [1], [2], the noise temperature of the first LNA must be reduced in order to reduce the necessary active area and the total system costs. Cooling the LNA locally would significantly decrease the noise figure but also the necessary power since not the whole system has to be cooled. For optimal thermal isolation, an LNA chip which only needs 6 bondwires has been chosen, 4 Ground and 2 signal wires. Biasing occurs on-chip. If the bondwires are 1.5mm long, the total heat conduction of the 6 bondwires is 31 mW, which is added to the power consumption of the LNA (30 mW). With a power of 61 mW to cool, the Peltier element can achieve a -T of 60K. With this system, a noise reduction of 30% has been measured with 0.5W of electrical power. For 15% noise reduction, only 35mW of electrical power was needed.

description: The Continuous Electron Beam Accelerator Facility (CEBAF) was built with a thermionic electron source and the three original experimental hall lines reflected this. A few years after beam delivery began a parity violation experiment was approved and two polarimeters were installed in the Hall A beam line without consultation with the accelerator physics group. The beam raster system was placed after the new Compton polarimeter, before one accelerator quadrupole and four quadrupoles in the new Moller polarimeter. It was very difficult to meet experimental requirements on envelope functions and raster shape with this arrangement so a member of the accelerator physics group had a sixth quadrupole installed downstream of the Moller polarimeter. All of the parity experiments in Hall A have been run with this still-unsatisfactory configuration. The MOLLER experiment is predicated on achieving a 2% error on a 32 ppb asymmetry. Beam line changes are required to meet the systematic error budget. This paper documents the existing beam line, an interim change which can be accomplished during a annual maintenance down, and the final configuration for MOLLER and subsequent experiments.

description: We study the dynamical breaking of chiral and color symmetries of dense quark matter in the ultrastatic hyperbolic spacetime $R\otimes H^3$ in the framework of an extended Nambu--Jona-Lasinio model. On the basis of analytical expressions for chiral and color condensates as functions of curvature and temperature, the phenomenon of dimensional reduction and gravitational catalysis of symmetry breaking in strong gravitational field is demonstrated in the regime of weak coupling constants. In the case of strong couplings it is shown that curvature leads to small corrections to the flat-space values of condensate and thus enhances the symmetry breaking effects. Finally, using numerical calculations phase transitions under the influence of chemical potential and negative curvature are considered and the phase portrait of the system is constructed.

description: Manufacturing electronic devices by printing techniques with low temperature sintering of nano-size material particles can revolutionize the electronics industry in coming years. The impact of this change to the industry can be significant enabling low-cost products and flexibility in manufacturing. implementation of a new production technology with new materials requires thorough elementary knowledge creation. It should be noticed that although some of first electronic devices ideally can be manufactured by printing, at the present several modules are in fact manufactured by using hybrid techniques (for instance photolithography, vapor depositions, spraying, etc...).

description: We derive a universal expression for the gravitational radiation energy spectrum $dE^{GW}/dω$ at sub-leading order emitted from a generic gravitational hard scattering of multi-particles or multi-bodies. Our result includes all $\mathcal{O}(ω)$ corrections to the gravitational radiation flux from a generic $2\rightarrow N$ collision, in both the cases of massless and massive particles/bodies. We also show the dependence of the radiation energy fluxby the quantum spin in case of particle collisions. Then, we consider the specific case of a gravitational elastic scattering of two massive bodies, i.e. $m+M\rightarrow m+M$ with $m,M$ the masses of the two bodies respectively. We demonstrate that in this case all $\mathcal{O}(ω)$ contributions to the energy flux exactly cancel each others. Nevertheless, we also show that, for a $2\rightarrow 2$ inelastic scattering, the inclusion of sub-leading soft gravitons leads to a not zero radiation flux, having a simple expression in certain asymptotic regimes. Our results can be applied to the case of Black Holes' collisions with possible testable implications in gravitational waves physics.
