Migratory flight of insect pests within a year-round distribution: European corn borer as a case study

Journal of Integrative Agriculture, 2018
Insect migratory flight differs fundamentally from most other kinds of flight behavior, in that it is non-appetitive. The adult is not searching for anything, and migratory flight is not terminated by encounters with potential resources.

Exploring the potential for cross-nesting structures in airport-choice analysis: A case-study of the Greater London area [PDF]

, 2006
The analysis of air-passengers’ choices of departure airport in multi-airport regions is a crucial component of transportation planning in many large metropolitan areas, and has been the topic of an increasing number of studies over recent years. In this

Heavy rainfall triggers increased nocturnal flight in desert populations of the Pacific black duck (Anas superciliosa) [PDF]

Scientific Reports, 2017
AbstractUnderstanding of avian nocturnal flight comes mainly from northern hemisphere species in seasonal temperate ecosystems where nocturnal flight is often precisely timed and entrained by annual photoperiod. Here we investigate patterns of nocturnal flight in waterbirds of Australian desert ecosystems that fly considerable distances to find ...

A Quantitative Printability Framework for Programmable Assembly of Pre‐Vascular Patterns via Laser‐Induced Forward Transfer

Advanced Healthcare Materials, EarlyView.
Laser‐Induced Forward Transfer (LIFT) is presented as a powerful micropatterning tool. An objective printability framework is developed to assess optimal printing parameter combinations. The technology is further explored for its ability to deterministically deposit microdroplets at predefined locations following CAD designs, enabling the patterning of

A Two-Stage Co-Evolution Multi-Objective Evolutionary Algorithm for UAV Trajectory Planning

Applied Sciences
With the increasing complexity of unmanned aerial vehicle (UAV) missions, single-objective optimization for UAV trajectory planning proves inadequate in handling multiple conflicting objectives.

Variation in Timing and Abundance of Elfins (Callophrys) (Lepidoptera: Lycaenidae) in Wisconsin During 1987-1999 [PDF]

, 2018
In Wisconsin during 1987-1999, we recorded elfin (Callophrys) individuals on 154 of 254 observation dates between 2 April and 11 July. The frosted elfin (C. irus) occurred only in central Wisconsin; brown (C. augustinus), hoary (C.

Peptomer Linkers Enable Kinetic Control over Co‐Delivery of Multiple Chemotherapeutics

Advanced Healthcare Materials, EarlyView.
A key challenge in combinatorial chemotherapeutic drug delivery is independent control over release kinetics, especially with drugs of similar size and structure. Here, peptoid substitutions to proteolytically degradable peptides enabled the design of fast and slow‐releasing drug linkers.

Flight Phenology of Spodoptera eridania (Stoll, 1781) (Lepidoptera: Noctuidae) in Its Native Range: A Baseline for Managing an Emerging Invasive Pest

Insects
Spodoptera eridania (Stoll, 1781) (Lepidoptera: Noctuidae) is an important pest with a broad host range and growing relevance due to its high dispersal capacity, recent invasions into Africa and Asia, and documented resistance to biological insecticides.

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

Advanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Flight initiation distance is repeatable and geographically flexible in greylag geese Anser anser

Journal of Avian Biology
The decision to flee from an approaching threat represents a trade‐off between the costs and benefits of flight. In research to date, particular interest has been given to the effects of urbanisation on predator escape behaviour.
