NOTE First Records of Alcathoe carolinensis Engelhardt and Synanthedon alleri (Engelhardt) in South Carolina, U.S.A.1

Clearwing moths (Lepidoptera: Sesiidae) are day-flying hornet and wasp mimics that can be found visiting flowers for nectar. Larvae bore in the roots, branches and trunks of woody and some herbaceous plants. Some of these larvae are pests in orchards, nurseries and commercial forestry operations. For example, Synanthe- don exitiosa (Say) and Synanthedon pictipes (Grote & Robinson) are major pests of peach [Prunus persica (L.) Batsch; Rosaceae] (Johnson et al. 2005), and Synanthe- don scitula (Harris) is a major pest of apple (Malus domestica Borkh.; Rosaceae) (Bergh & Leskey 2003). These species, and Podosesia syringae (Harris), Podosesia aureocincta Purrington & Nielsen and Paranthrene simulans (Grote) are pests of ornamental trees (Brown and Mizell 1993, Braxton & Raupp 1995, Held 2019). About 135 sesiid species in 20 genera occur in North America (Pühringer & Kallies 2004, Pohl et al. 2016). Forty-four species are likely to occur in South Carolina based on collection records from South Carolina and neighboring states documented in Eichlin & Duckworth (1988). This species richness has not been validated with a comprehensive survey of sesiid diversity in the state. As a first step to better understand sesiid species diversity in South Carolina, a survey was conducted in three counties (Darlington, Georgetown and Pickens) from March 2011 to December 2013. A mixed pine-hardwood forest, an ornamental plant nursery and a botanical garden were surveyed in each of Darlington and Georgetown Counties to diversify the habitats and outcome of this exploratory survey. In Pickens County, a single ornamental plant nursery was surveyed. Surveyed locations in Georgetown County lay within the Sea Island and Coastal Marsh Ecoregion, those in Darlington County within the Atlantic Southern Loam Plain Ecoregion, and that in Pickens County within the Southern Outer Piedmont Ecoregion (Griffith et al. 2002). Locations within a county were separated by at least 20 km

Stationary wave patterns generated by an impurity moving with supersonic velocity through a Bose-Einstein condensate

Formation of stationary 3D wave patterns generated by a small point-like impurity moving through a Bose-Einstein condensate with supersonic velocity is studied. Asymptotic formulae for a stationary far-field density distribution are obtained. Comparison with three-dimensional numerical simulations demonstrates that these formulae are accurate enough already at distances from the obstacle equal to a few wavelengths.Comment: 7 pages, 3 figure

Lower bounds on the blow-up rate of the axisymmetric Navier-Stokes equations II

Consider axisymmetric strong solutions of the incompressible Navier-Stokes equations in $\R^3$ with non-trivial swirl. Let $z$ denote the axis of symmetry and $r$ measure the distance to the z-axis. Suppose the solution satisfies either $|v (x,t)| \le C_*{|t|^{-1/2}}$ or, for some \e > 0, $|v (x,t)| \le C_* r^{-1+\epsilon} |t|^{-\epsilon /2}$ for $-T_0\le t < 0$ and $0<C_*<\infty$ allowed to be large. We prove that $v$ is regular at time zero.Comment: More explanations and a new appendi

Selective interlayer ferromagnetic coupling between the Cu spins in YBa2_2 Cu3_3 O7−x_{7-x} grown on top of La0.7_{0.7} Ca0.3_{0.3} MnO3_3

Studies to date on ferromagnet/d-wave superconductor heterostructures focus mainly on the effects at or near the interfaces while the response of bulk properties to heterostructuring is overlooked. Here we use resonant soft x-ray scattering spectroscopy to reveal a novel c-axis ferromagnetic coupling between the in-plane Cu spins in YBa$_2$ Cu$_3$ O$_{7-x}$ (YBCO) superconductor when it is grown on top of ferromagnetic La$_{0.7}$ Ca$_{0.3}$ MnO$_3$ (LCMO) manganite layer. This coupling, present in both normal and superconducting states of YBCO, is sensitive to the interfacial termination such that it is only observed in bilayers with MnO_2but not with La$_{0.7}$ Ca$_{0.3}$ interfacial termination. Such contrasting behaviors, we propose, are due to distinct energetic of CuO chain and CuO$_2$ plane at the La$_{0.7}$ Ca$_{0.3}$ and MnO$_2$ terminated interfaces respectively, therefore influencing the transfer of spin-polarized electrons from manganite to cuprate differently. Our findings suggest that the superconducting/ferromagnetic bilayers with proper interfacial engineering can be good candidates for searching the theorized Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) state in cuprates and studying the competing quantum orders in highly correlated electron systems.Comment: Please note the change of the title.

Wearable, Multimodal, Biosignal Acquisition System for Potential Critical and Emergency Applications

For emergency or intensive-care units (ICUs), patients with unclear consciousness or unstable hemodynamics often require aggressive monitoring by multiple monitors. Complicated pipelines or lines increase the burden on patients and inconvenience for medical personnel. Currently, many commercial devices provide related functionalities. However, most devices measure only one biological signal, which can increase the budget for users and cause difficulty in remote integration. In this study, we develop a wearable device that integrates electrocardiography (ECG), electroencephalography (EEG), and blood oxygen machines for medical applications with the hope that it can be applied in the future. We develop an integrated multiple-biosignal recording system based on a modular design. The developed system monitors and records EEG, ECG, and peripheral oxygen saturation (SpO2) signals for health purposes simultaneously in a single setting. We use a logic level converter to connect the developed EEG module (BR8), ECG module, and SpO2 module to a microcontroller (Arduino). The modular data are then smoothly encoded and decoded through consistent overhead byte stuffing (COBS). This developed system has passed simulation tests and exhibited proper functioning of all modules and subsystems. In the future, the functionalities of the proposed system can be expanded with additional modules to support various emergency or ICU applications
