Covid-19 antibody discovery with topology-enhanced learning models by Wang, Zihong

“…The recent global spread of Coronavirus disease 2019 (COVID-19) has been fueled by the appearance of various new variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including Alpha, Beta, Gamma, Delta, Omicron, etc. The impact of variants on infectivity and monoclonal antibodies (mAbs) effectiveness is largely determined by how related receptor-binding domain (RBD) mutations affect ACE2 and antibody binding. …”

Fractional integration and optimal estimates for elliptic systems by Hernandez, Felipe, Spector, Daniel

“…In this paper we give an affirmative answer to the Euclidean analogue of a question of Bourgain and Brezis concerning the optimal Lorentz estimate for a Div–Curl system: If $$F \in L^1(\mathbb {R}^3;\mathbb {R}^3)$$ F ∈ L 1 ( R 3 ; R 3 ) satisfies $$\text {div}F=0$$ div F = 0 in the sense of distributions, then the function $$Z=\text {curl} (-\Delta )^{-1} F$$ Z = curl ( - Δ ) - 1 F satisfies $$\begin{aligned} \text {curl } Z&= F \\ \text {div } Z&= 0 \end{aligned}$$ curl Z = F div Z = 0 and there exists a constant $$C>0$$ C > 0 such that $$\begin{aligned} \Vert Z\Vert _{L^{3/2,1}(\mathbb {R}^3;\mathbb {R}^3)} \le C\Vert F\Vert _{L^{1}(\mathbb {R}^3;\mathbb {R}^3)}. …”

Analysis of brain signals by Tan, Yi Bing

“…The numerous brainwave states include Gamma (30-70 Hz), Beta (13-30 Hz), Alpha (8-12 Hz), Theta (4-8 Hz) and Delta (0.5-4 Hz). It is observed that each particular state of brainwave changes the state of consciousness in us and has a very close relationship and diverse effect on the overall health condition. …”

Polarity-driven laminar pattern formation by lateral-inhibition in 2D and 3D bilayer geometries by Moore, JW, Dale, TC, Woolley, TE

“…In agreement with the mathematical implications of strict signalling polarity induced on the cells, we propose an adhesion-dependent Notch-Delta biological process that has the potential to initiate bilayer stratification in a developing mammary organoid.…”

Global monitoring of volcanic SO2 degassing with unprecedented resolution from TROPOMI onboard Sentinel-5 Precursor by Barrington, Charlotte, Taisne, Benoit, Theys, N., Hedelt, P., De Smedt, I., Lerot, C., Yu, H., Vlietinck, J., Pedergnana, M., Arellano, S., Galle, B., Fernandez, D., Carlito, C.
