Unpredictable air movements have proved to be a problem in previous studies investigating robot communication by means of airborne pheromone chemicals. The project described in this paper investigates the use of air vortex rings as a means of carrying pheromone chemicals between transmitting and receiving robots. Sensitivity to chemicals including pheromones released by conspecifics is essential for many aspects of an insect's life. They assist in finding food, locating a mate, avoiding danger and help coordinate the activities of social insects. In the future, autonomous robots will be challenged by many situations similar to those that face insects and other simple creatures. Chemical communication may prove useful for these robots as well. This paper describes the equipment developed for generating and detecting vortex rings. results of experiments involving location and tracking of a sequence of pheromone vortex rings are also presented.

In a recent publication it was shown that homonuclear scalar couplings in directly detected protein NMr spectra can be“decoupled”using deep neural networks,including cases where existing methods fail[1].The work harkens back to the introduction of maximum entropy and non-uniform sampling,and it elegantly illustrates how new approaches can be devised in the conceptualization of NMr experiments,freeing researchers from conventional thinking and *** work opens up a new era in biomolecular NMr spectroscopy,where experimental design is tailored towards processing with deep neural networks.(https://***/10.1021/jacs.1c04010).

Non-conventional feed ingredients are receiving more interest in their ability to increase farming effi-ciency,sustainability and animal *** objective of this study was to determine the optimal rate of inclusion level of the full-fat black soldier fly larvae(BSFL)in broiler diets and to evaluate their impact on performance,nutrient digestibility,and the immune system(blood cells and intraepithelial lymphocytes).A total of 400 male day-old ross 308 broilers were randomly assigned to 5 treatment groups with 8 replicates *** inclusion levels of full-fat BSFL were investigated across starter(0,2.5%,5%,7.5%and 10%),grower and finisher diets(0,5%,10%,15%and 20%).All diets were formulated based on digestible amino acid values according to the Aviagen(2016)recommendations.A polynomial regression at different degrees was performed to analyse broiler performance parameters(body weight,body weight gain,feed intake,and feed conversion ratio),nutrient digestibility,and blood cell *** lymphocyte population data was analysed performing univariate linear *** the entire experimental period(from 2 to 42 d),BSFL inclusion levels decreased the feed conversion ratio by 10%in broilers that received 20%BSFL in their diets(Preased linearly by 47.7%and 35.9%,respectively,with up to 20%BSFL inclusion(Prease in CD3+T lymphocytes and a 9.7-fold decrease of CD3+CD8+intestinal cytotoxic T lymphocytes occurred in broilers fed 20%BSFL compared to the control *** findings suggest that the inclusion of BSFL can improve broiler performance and potentially reduce immune response energy expenditure in birds fed 20%BSFL for 42 d.

This paper presents a novel robotic sensor system that can monitor volatile chemicals and airflow. The system is modelled on characteristics of the human body that are thought to have a significant influence on the human odour and airflow senses. In particular, the effect of buoyant airflow due to body heat acts to gather volatile chemicals over large areas of the human body and carry them to the nose. It is postulated that this effect increases the receptive area for human olfaction. In addition, the interaction between rising air heated by the body and external airflow produces a temperature distribution about head height that can be used to infer airflow direction and magnitude. A heated sensor system was constructed to investigate these effects and the resulting sensor was mounted on a mobile robot. The design of the sensor system is described. results are presented which demonstrate its ability to measure airflow direction and detect chemical signals over a wider receptive field compared with an unheated sensor.

Hepatic ischemia-reperfusion injury (IrI) limits access to transplantation. Heme oxygenase-1 (HO-1) is a powerful antioxidant enzyme which degrades free heme into biliverdin,free iron and carbon monoxide. HO-1 and its metabolites have the ability to modulate a wide variety of inflammatory disorders including hepatic IrI. Mechanisms of this protective effect include reduction of oxygen free radicals,alteration of macrophage and T cell phenotype. Further work is required to understand the physiological importance of the many actions of HO-1 identified experimentally,and to harness the protective effect of HO-1 for therapeutic potential.
