Abstract Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the flexibility animals need for adapting to seasonal unpredictable habitats. Similar ecological challenges would have been important drivers throughout human evolution. However, studies examining influence of environmental variability on within-species diversity lacking despite critical assumption that population diversification precedes genetic divergence speciation. Here,...
More than just numbers We often frame negative human impacts on animal species in terms of individuals reduced or regions from which are absent. However, activities likely affecting more complex ways these figures can capture. Kühl et al. studied behavioral and cultural diversity our closest relative, the chimpanzee. They found that human-mediated disturbance is reducing traits. Human influence thus goes well beyond simple loss populations species, leading to change even where persist....
Older adults are normally characterized as consumers, rather than producers, of digital content. Current research concerning the design technologies for older typically focuses on providing access to resources. Access is important, but often insufficient, especially when establishing new social relationships. This paper investigates nature and role content that has been created by adults, purpose forging We present a unique field study in which seven (aged 71-92 years), who did not know each...
This paper considers what we can learn from the experiences of people who choose not to participate in technology-based social interventions. We conducted ethnographically-informed field studies with socially isolated older adults, used and evaluated a new iPad application designed help build connections. In this reflect on how values assumptions guiding technological intervention were always shared by those participating evaluation. Drawing our notes interviews adults chose discontinue...
Today's vehicles are advancing from stand-alone transportation means to vehicle-to-vehicle, and vehicle-to-infrastructure communications enabled devices which able exchange data through the communication infrastructure. As IoT remain intrinsically linked together, fast-changing mobility landscape of intent-based networking for Internet connected comes with a great risk security privacy violations. This paper considers issues in distributed edge computing, is communicated between number layer...
Machine learning, especially deep is used increasingly to enable better solutions for data management tasks previously solved by other means, including database indexing. A recent study shows that a neural network can not only learn predict the disk address of value associated with one-dimensional search key but also outperform B-tree-based indexing, thus promises speed up broad range queries rely on B-trees efficient access. We consider problem learning an index two-dimensional spatial...
ABSTRACT Ongoing ecosystem change and biodiversity decline across the Afrotropics call for tools to monitor state of or elements extensive spatial temporal scales. We assessed relationships in co‐occurrence patterns between great apes other medium large‐bodied mammals evaluate whether ape abundance serves as a proxy mammal diversity broad used camera trap footage recorded at 22 research sites, each known harbor population chimpanzees, some additionally gorillas, 12 sub‐Saharan African...
The moving k nearest neighbor (M NN) query finds the neighbors of a point continuously. high potential reducing processing cost as well large spectrum associated applications have attracted considerable attention to this type from database community. This paper presents an incremental safe-region-based technique for answering M NN queries, called V*-Diagram. In general, safe region is set points where can move without changing answer. Traditional safe-region approaches compute based on data...
Abstract In group living animals, especially among primates, there is consistent evidence that high‐ranking males gain a higher reproductive output than low‐ranking males. Primate studies have shown male coalitions and sociality can impact fitness; however, it remains unclear whether could potentially increase their fitness by preferentially supporting socializing with females. Here we investigate patterns of interventions the effect on in rhesus macaques ( Macaca mulatta ) particular focus...
Attaining efficient road traffic through optimizing travel time and energy consumption without compromising safety is a key goal in transport telematics. Lane-changes merging have vital role modelling on-ramp off-ramp bottlenecks. Near on-ramps off-ramps, they are often major factors to cause hazards breakdowns. In this paper, we address the problem of improving/optimizing at thus reducing order merge two streams communication-and sensor-enabled vehicles, define propose proactive optimal...
Dispersal has been suggested to be challenging, especially for species that heavily rely on social learning knowledge acquisition. One of the obstacles migrants face is how cope with an unfamiliar, new habitat, which may involve from resident individuals. So far, only very few studies have looked at in after dispersal. Here we examine migrant male orangutans use a behavior called “peering” (an indicator observational learning), learn local In total, analyzed 4,009 daily dyadic associations...
User privacy in location-based services has attracted great interest the research community. We introduce a novel framework based on decentralized architecture for preserving group nearest neighbor queries. A (GNN) query returns location of meeting place that minimizes aggregate distance from spread out users; example, users can ask restaurant total travel them. identify challenges user GNN queries and provide comprehensive solution to this problem. In our approach, their locations as...
We propose and study a new type of location optimization problem: given set clients existing facilities, we select from potential locations for establishing facility so that the average distance between client her nearest is minimized. call this problem min-dist selection problem, which has wide range applications in urban development simulation, massively multiplayer online games, decision support systems. explore two common approaches to problems methods based on those solving problem....
Abstract In multimale groups where females mate promiscuously, male–infant associations have rarely been studied. However, recent studies shown that males selectively support their offspring during agonistic conflicts with other juveniles and father's presence accelerates maturation. Furthermore, it was invest in unrelated infants to enhance future mating success the infant's mother. Hence, infant care might provide fitness gain for males. Here, we investigate rhesus macaques ( Macaca...
