Modelling and PI control of an irrigation canal [PDF]

2003 European Control Conference (ECC), 2003
The main goal of this paper is to expose and validate a methodology to design efficient automatic controllers for irrigation canals, based on the Saint-Venant model. This model-based methodology enables to design controllers at the design stage (when the canal is not already built).

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

Advanced Science, EarlyView.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Iron‐Tannic Acid Hydrogel Mediated Mild Photothermal Therapy Combined With Ferroptosis Enhances Anti‐Tumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
An injectable gelatin‐based tannic acid–iron hydrogel with mild photothermal therapy could not only induce immunogenic cell death, but also elicit ferroptosis of both tumor cells and tumor‐associated macrophages, resulting in DC maturation, T‐cell infiltration and down‐regulation of ferroptosis‐sensitive M2‐type TAMs levels.

A Fuzzy Control Irrigation System For Cottonfield [PDF]

, 2009
A fuzzy control irrigation system for cotton field is presented in this paper. The system is composed of host computer, slave computer controller, communication module, soil water sensors, valve controllers, and system software. A fuzzy control model is constructed to control the irrigation time and irrigation quantity for cotton filed.

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

Advanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Control of microorganisms in vitro by endodontic irrigants [PDF]

Brazilian Dental Journal, 2003
The aim of this study was to determine the minimum inhibitory concentration (MIC) and antimicrobial effectiveness by the direct exposure test of 4 endodontic irrigants [1% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), 1% calcium hydroxide (Ca(OH)2; prepared with 1 g of Ca(OH)2 and 100 mL of sterile distilled water), a solution of Ca(OH)2 ...
