The clinical success of monoclonal antibodies to treat diseases across nearly every therapeutic area has spurred advances in bispecific antibody technology with the goal of cost-effectively combining various therapies or providing novel mechanisms for disease intervention. Many novel bispecific antibodies are now in clinical development or the late pre-clinical setting. A new horizon exists for novel molecular entities with the ability to bind three or more antigens. Here we describe the production and characterization of novel trispecific antibody-like proteins denoted 'OrthoTsAbs' that self-assemble through the application of engineered antibody domain interfaces.

Grocery Shopping Under Simplified Marginal Value Theorem Predictions.

Hum Nat

January 2025

Institute of Psychology, Faculty of Life Sciences / Fakultät für Lebenswissenschaften, Technische Universität Braunschweig, Braunschweig, Germany.

This study examined whether supermarkets can be considered patches in the marginal value theorem (MVT) sense despite their particular features and whether they are models of human food foraging in resource-dense conditions. On the basis of the MVT, the quantitative relationship between gains in the Euro and patch residence time was modeled as an exponential growth function toward an upper asymptote, allowing the choice of an optimal strategy under diminishing returns. N = 61 participants were interviewed about their current shopping trip and contextual variables at a German supermarket and provided data to estimate relevant model parameters.

Titanium alloy is known for its low thermal conductivity, small elastic modulus, and propensity for work hardening, posing challenges in predicting surface quality post high-speed milling. Since surface quality significantly influences wear resistance, fatigue strength, and corrosion resistance of parts, optimizing milling parameters becomes crucial for enhancing service performance. This paper proposes a milling parameter optimization method utilizing the snake algorithm with multi-strategy fusion to improve surface quality.

Precisely controlling quantum states is relevant in next-generation quantum computing, encryption, and sensing. Chiral organic chromophores host unique light-matter interactions, which allow them to manipulate the quantized circular polarization of photons. Axially chiral organic scaffolds, such as helicenes or twisted acenes, are powerful motifs in chiral light manipulation.
