We present a proof of concept for a spectrally selective thermal midIR source based on nanopatterned graphene (NPG) with a typical mobility of CVDgrown graphene (up to 3000
Extensional flow properties of polymer solutions in volatile solvents govern many industriallyrelevant coating processes, but existing instrumentation lacks the environment necessary to control evaporation. To mitigate evaporation during drippingontosubstrate (DoS) extensional rheology measurements, we developed a chamber to enclose the sample in an environment saturated with solvent vapor. We validated the evaporationcontrolled DoS device by measuring a model high molecular weight polyethylene oxide (PEO) in various organic solvents both inside and outside of the chamber. Evaporation substantially increased the extensional relaxation time

Abstract ), ensuring scalability to large areas. For that, we solve the electrostatic problem of a conducting hyperboloid with an elliptical wormhole in the presence of an$$\hbox {cm}^2\,\hbox {V}^{1}\,\hbox {s}^{1}$$ ${\text{cm}}^{2}\phantom{\rule{0ex}{0ex}}{\text{V}}^{1}\phantom{\rule{0ex}{0ex}}{\text{s}}^{1}$inplane electric field. The localized surface plasmons (LSPs) on the NPG sheet, partially hybridized with graphene phonons and surface phonons of the neighboring materials, allow for the control and tuning of the thermal emission spectrum in the wavelength regime from to 12$$\lambda =3$$ $\lambda =3$ m by adjusting the size of and distance between the circular holes in a hexagonal or square lattice structure. Most importantly, the LSPs along with an optical cavity increase the emittance of graphene from about 2.3% for pristine graphene to 80% for NPG, thereby outperforming stateoftheart pristine graphene light sources operating in the nearinfrared by at least a factor of 100. According to our COMSOL calculations, a maximum emission power per area of$$\upmu$$ $\mu $ W/$$11\times 10^3$$ $11\times {10}^{3}$ at$$\hbox {m}^2$$ ${\text{m}}^{2}$ K for a bias voltage of$$T=2000$$ $T=2000$ V is achieved by controlling the temperature of the hot electrons through the Joule heating. By generalizing Planck’s theory to any grey body and deriving the completely general nonlocal fluctuationdissipation theorem with nonlocal response of surface plasmons in the random phase approximation, we show that the coherence length of the graphene plasmons and the thermally emitted photons can be as large as 13$$V=23$$ $V=23$ m and 150$$\upmu$$ $\mu $ m, respectively, providing the opportunity to create phased arrays made of nanoantennas represented by the holes in NPG. The spatial phase variation of the coherence allows for beamsteering of the thermal emission in the range between$$\upmu$$ $\mu $ and$$12^\circ$$ ${12}^{\circ}$ by tuning the Fermi energy between$$80^\circ$$ ${80}^{\circ}$ eV and$$E_F=1.0$$ ${E}_{F}=1.0$ eV through the gate voltage. Our analysis of the nonlocal hydrodynamic response leads to the conjecture that the diffusion length and viscosity in graphene are frequencydependent. Using finitedifference time domain calculations, coupled mode theory, and RPA, we develop the model of a midIR light source based on NPG, which will pave the way to graphenebased optical midIR communication, midIR color displays, midIR spectroscopy, and virus detection.$$E_F=0.25$$ ${E}_{F}=0.25$ 
Abstract A method for modelling the prompt production of molecular states using the hadronic rescattering framework of the generalpurpose Pythia event generator is introduced. Production cross sections of possible exotic hadronic molecules via hadronic rescattering at the LHC are calculated for the
resonance, a possible tetraquark state, as well as three possible pentaquark states,$$\chi _{c1}(3872)$$ ${\chi}_{c1}\left(3872\right)$ ,$$P_c^+(4312)$$ ${P}_{c}^{+}\left(4312\right)$ , and$$P_c^+(4440)$$ ${P}_{c}^{+}\left(4440\right)$ . For the$$P_c^+(4457)$$ ${P}_{c}^{+}\left(4457\right)$ states, the expected cross section from$$P_c^+$$ ${P}_{c}^{+}$ decays is compared to the hadronicrescattering production. The$$\Lambda _b$$ ${\Lambda}_{b}$ cross section is compared to the fiducial$$\chi _{c1}(3872)$$ ${\chi}_{c1}\left(3872\right)$ crosssection measurement by LHCb and found to contribute at a level of$$\chi _{c1}(3872)$$ ${\chi}_{c1}\left(3872\right)$ . Finally, the expected yields of$${\mathcal {O}({1\%})}$$ $O\left(1\%\right)$ production from hadronic rescattering during Run 3 of LHCb are estimated. The prompt background is found to be significantly larger than the prompt$$\mathrm {P_c^{+}}$$ ${P}_{c}^{+}$ signal from hadronic rescattering.$$\mathrm {P_c^{+}}$$ ${P}_{c}^{+}$ 
Abstract An Eulerian walk (or Eulerian trail) is a walk (resp. trail) that visits every edge of a graph
G at least (resp. exactly) once. This notion was first discussed by Leonhard Euler while solving the famous Seven Bridges of Königsberg problem in 1736. But what if Euler had to take a bus? In a temporal graph , with$$\varvec{(G,\lambda )}$$ $(G,\lambda )$ , an edge$$\varvec{\lambda : E(G)}\varvec{\rightarrow } \varvec{2}^{\varvec{[\tau ]}}$$ $\lambda :E\left(G\right)\to {2}^{\left[\tau \right]}$ is available only at the times specified by$$\varvec{e}\varvec{\in } \varvec{E(G)}$$ $e\in E\left(G\right)$ , in the same way the connections of the public transportation network of a city or of sightseeing tours are available only at scheduled times. In this paper, we deal with temporal walks, local trails, and trails, respectively referring to edge traversal with no constraints, constrained to not repeating the same edge in a single timestamp, and constrained to never repeating the same edge throughout the entire traversal. We show that, if the edges are always available, then deciding whether$$\varvec{\lambda (e)}\varvec{\subseteq } \varvec{[\tau ]}$$ $\lambda \left(e\right)\subseteq \left[\tau \right]$ has a temporal walk or trail is polynomial, while deciding whether it has a local trail is$$\varvec{(G,\lambda )}$$ $(G,\lambda )$ complete even if$$\varvec{\texttt {NP}}$$ $\mathrm{NP}$ . In contrast, in the general case, solving any of these problems is$$\varvec{\tau = 2}$$ $\tau =2$ complete, even under very strict hypotheses. We finally give$$\varvec{\texttt {NP}}$$ $\mathrm{NP}$ algorithms parametrized by$$\varvec{\texttt {XP}}$$ $\mathrm{XP}$ for walks, and by$$\varvec{\tau }$$ $\tau $ for trails and local trails, where$$\varvec{\tau +tw(G)}$$ $\tau +tw\left(G\right)$ refers to the treewidth of$$\varvec{tw(G)}$$ $tw\left(G\right)$ .$$\varvec{G}$$ $G$ 
Abstract We present a strategy for the design of ferromagnetic materials with exceptionally low magnetic hysteresis, quantified by coercivity. In this strategy, we use a micromagnetic algorithm that we have developed in previous research and which has been validated by its success in solving the “Permalloy Problem”—the wellknown difficulty of predicting the composition 78.5% Ni of the lowest coercivity in the Fe–Ni system—and by the insight it provides into the “Coercivity Paradox” of W. F. Brown. Unexpectedly, the design strategy predicts that cubic materials with large saturation magnetization
m _{s}and large magnetocrystalline anisotropy constantκ _{1}will have low coercivity on the order of that of Permalloy, as long as the magnetostriction constantsλ _{100},λ _{111}are tuned to special values. The explicit prediction for a cubic material with low coercivity is the dimensionless number for 〈100〉 easy axes. The results would seem to have broad potential application, especially to magnetic materials of interest in energy research.$$({c}_{11}{c}_{12}){\lambda }_{100}^{2}/(2{\kappa }_{1})=81$$ $\left({c}_{11}{c}_{12}\right){\lambda}_{100}^{2}/\left(2{\kappa}_{1}\right)=81$ 
Abstract Thin film evaporation is a widelyused thermal management solution for micro/nanodevices with high energy densities. Local measurements of the evaporation rate at a liquidvapor interface, however, are limited. We present a continuous profile of the evaporation heat transfer coefficient (
) in the submicron thin film region of a water meniscus obtained through local measurements interpreted by a machine learned surrogate of the physical system. Frequency domain thermoreflectance (FDTR), a noncontact laserbased method with micrometer lateral resolution, is used to induce and measure the meniscus evaporation. A neural network is then trained using finite element simulations to extract the$$h_{\text {evap}}$$ ${h}_{\text{evap}}$ profile from the FDTR data. For a substrate superheat of 20 K, the maximum$$h_{\text {evap}}$$ ${h}_{\text{evap}}$ is$$h_{\text {evap}}$$ ${h}_{\text{evap}}$ MW/$$1.0_{0.3}^{+0.5}$$ $1.{0}_{0.3}^{+0.5}$ K at a film thickness of$$\text {m}^2$$ ${\text{m}}^{2}$ nm. This ultrahigh$$15_{3}^{+29}$$ ${15}_{3}^{+29}$ value is two orders of magnitude larger than the heat transfer coefficient for singlephase forced convection or evaporation from a bulk liquid. Under the assumption of constant wall temperature, our profiles of$$h_{\text {evap}}$$ ${h}_{\text{evap}}$ and meniscus thickness suggest that 62% of the heat transfer comes from the region lying 0.1–1 μm from the meniscus edge, whereas just 29% comes from the next 100 μm.$$h_{\text {evap}}$$ ${h}_{\text{evap}}$
