Summary: One-loop electroweak corrections to the annihilation cross sections of dark matter in the Higgs resonance region of the inert doublet model are investigated. The regularization of the amplitude at tree level and at one loop, as well as the renormalization of a key parameter of the model, are thoroughly scrutinized. Discussions go beyond relic density calculation and inert doublet model to address technical issues in a wider context.

Summary: This study examines the relic density of the light mass dark matter region in the inert doublet model (IDM), focusing on coannihilation processes and one-loop electroweak corrections. The dependence on a parameter describing the self-interaction of new scalars is found to be crucial, highlighting the significance of this parameter which is not accessible in tree-level calculations of standard model-IDM interactions.

Summary: This study investigates one-loop electroweak corrections for dark matter annihilation processes, highlighting their significant impact on controlling parameters and renormalization scale in the dark sector. The findings suggest that these corrections should be considered as a theoretical uncertainty in analyses based on tree-level cross sections of relic density calculations.

Summary: In this work, approximate next-to-next-to-leading order (NNLO) corrections to unpolarized and polarized semi-inclusive deep-inelastic scattering are determined using the threshold resummation formalism. The expansion of the resummed expression includes all logarithmically enhanced terms at threshold, and numerical estimates suggest the significance of these NNLO terms in reducing scale dependence.

Summary: The paper addresses the calculation of full one-loop corrections of DM annihilation cross sections in the low mass region of the IDM. It reviews the renormalization of the model in different schemes and discusses how to minimize scale dependence. A new criterion on the perturbativity of the IDM is introduced, delimiting the allowed parameter space with benchmark points covering various mechanisms for a viable relic density of DM.

Summary: This study uses geodynamic models to investigate the morphology, stress state, and thermal structure of the Tonga-Fiji subduction zone, revealing that the collision of relic slab from the Vanuatu Trench with the Tonga slab may control the steeper dip of the Tonga slab and earthquakes in the mantle transition zone. The findings support the hypothesis that local slab temperature likely controls rupture of deep earthquakes.

Summary: In this study, Ga-doped In2O3 with nanosized pore structures were prepared using a hydrothermal method combined with spark plasma sintering. The introduction of nanopores significantly reduced the thermal conductivity of the material, resulting in a high ZT value of 0.383 at 800 degrees C. This research indicates that nanopores can serve as competitive strategy for achieving high ZT values in thermoelectric materials.

Summary: In this study, a double-beam synergistically controlled triplet-triplet annihilation upconversion (TTA-UC) system was developed, which could increase the UC emission intensity by more than 6-fold using the thermal lensing effect of a near-infrared (NIR)-absorbing solution. The collimation effect of a divergent 532 nm laser beam achieved through the concave lens effect significantly increased the excitation power density of the UC system, leading to the increment of UC emission intensity. The ON/OFF ratio of the TTA-UC switching could be conveniently regulated by the output power of either the 532 nm laser or 721 nm laser, as well as the concentration and compounds of the photothermal lens effect solution. The visible/NIR stimuli-responsive TTA-UC system was applied to photolithography to increase both the speed and depth of the photo printing.

Summary: Conducting polymers with 1D morphology have advantages for thermoelectric applications by improving electrical conductivity. Using an appropriate organic compound to create a self-degraded template is key for producing enhanced TE properties in 1D conducting polymers. In this study, PPy nanotubes synthesized with varying MO concentrations showed improved TE performance and a maximum power factor of 1 mu W/m k².

Summary: Aminated cellulose nanofibers (A-CNF) with high thermal stability, crystallinity, and dispersion stability are extracted from biological grinding biomass through one-pot microwave-hydrothermal synthesis. These A-CNF serve as excellent reinforcing and curing agents in constructing high performance epoxy nano composites, demonstrating significant enhancements in thermal conductivity, thermal expansion reduction, and Young's modulus. This process may facilitate a closed-loop carbon cycle in the production and utilization of biomass.

Summary: In this work, all-dielectric insulated plasmonic absorbers are demonstrated as efficient self-floating interfacial solar evaporators with a measured efficiency of approximately 80% under one sun. The enhanced energy transfer process can be attributed to the synergistic effect of plasmon-enhanced solar absorption, broadband light induced thermal localization and/or insulation, as well as efficient mass transport channels. These results provide new insights into the understanding of plasmonic solar thermal conversion and inspire further development in this field.

Summary: The thermal effect plays a significant role in soil consolidation, particularly in cold regions. Previous studies have neglected the influence of thermal effect on consolidation and final settlement. In this research, a mathematical model considering the thermal effect is proposed and validated against other solutions. Analysis shows that temperature, stress ratios, consolidation time, the ratio of compression index to permeability index, and interface parameters are important factors in the consolidation process. Thus, the thermal effect must be taken into account in cold region soil consolidation calculations.

Summary: A unique Sol-gel-based method was used to deposit flame-retardant coatings on cotton fabric. SEM analysis revealed significant coverage of the fabric by the coatings. ATR-FTIR and EDS analysis provided compositional information of the coated samples. TGA and VFT tests showed that the coatings obtained for 5 h and zero heat-treatment time exhibited high resistance and excellent combustion properties, with a 28.86% char residue obtained for one sample (ET-5h-RT).

Summary: The asymptotic expansion of quantum knot invariants in complex Chern-Simons theory gives rise to factorially divergent formal power series. These series are conjectured to be resurgent functions, with their Stokes automorphism given by a pair of matrices of q-series with integer coefficients derived from a pair of linear q-difference equations. It is further conjectured that for a hyperbolic knot, a distinguished entry of those matrices equals the Dimofte-Gaiotto-Gukov 3D-index, indicating a counting of BPS states.

Summary: This paper addresses the computation of elliptic genera for 6d (1, 0) SCFTs, introducing blowup equations and various computational techniques. The unity and vanishing blowup equations are classified, with a focus on rank one theories. Techniques such as recursion formulas, orbit expansions, and BPS expansions are developed, along with a gluing rule for higher-rank theories to derive blowup equations. Examples of elliptic blowup equations are explicitly given for specific cases.

Summary: Topological string theory near the conifold point of a Calabi-Yau threefold gives rise to factorially divergent power series which encode all-genus enumerative information. We conjecture that the corresponding Stokes constants are integer invariants of the Calabi-Yau threefold and calculate these constants in some toric examples, confirming our conjecture.

Summary: In this note, the resurgent structure of the sl(2, DOUBLE-STRUCK CAPITAL C) Chern-Simons state integral model on knot complements S-3\4(1), S-3\5(2) with generic discrete level k >= 1 and with small boundary holonomy deformation is studied. The resurgent structure of the asymptotic series is universal despite the increasing complication of the series as the level k increases: both the distribution of Borel plane singularities and the associated Stokes constants are independent of the level k.
