Feasibility of Software-Based Duty Cycling of GPS for Trajectory-Based Services
No full textEnergy-efficient localization is increasingly important for many types of smartphone apps. The research community has argued that fixed duty cycling of GPS is not a good choice for trajectory-based services concerning route accuracy. In this paper, we describe the design and implementation of a highly accurate map matching and path construction algorithm. Furthermore, with thorough field experiments, we show that fixed duty cycling of a smartphone GPS receiver is a feasible approach for trajectory-based services, and it can achieve considerable energy conservation without sacrificing much route accuracy. When increasing the GPS sampling period beyond 120 seconds, it saves at least 78% energy in comparison to continuous GPS sampling, while the loss of route accuracy tends to be stable around 23%.Li, Xiaohan, Yuan, Fengpeng, & Lindqvist, Janne.

Fig. 4 in Early transcriptional response of terpenoid metabolism to Colletotrichum gloeosporioides in a resistant wild strawberry Fragaria nilgerrensis
No full textFig. 4. Schematic illustration of general terpenoid biosynthesis pathways showing identified unigenes from F. nilgerrensis leaf transcriptome data. The interconvertible precursors IPP and DMAPP, two phosphorylated C5 unites, are produced by the MVA and MEP pathways which are exchangeable from both compartmentations. The chloroplast is a major site for synthesis of hemiterpene (C5), monoterpenoids (C10), diterpenoids (C20) carotenoids (C40) and chlorophyll, while the cytosol and other organelle are responsible for synthesis of monoterpenoids (C10), sesquiterpene (C15) and triterpene (C30). But that is not strictly conclusive. Arrow with lines indicate reactions catalyzed by enzymes and the encoding genes, with unigenes identified in this experiment boxed. The color highlights are for better visualization.

Fragaria nilgerrensis leaves
No full text4.2. Isolation of phytochemical and volatile compounds from F. nilgerrensis leaves At different hours (0, 3, 6, 12, 18, 24, 48 and 72 h) after infected with C. gloeosporioides, leaves were removed and collected from the plants, frozen immediately in liquid nitrogen and then stored at 80 ◦ C for future use. Each cryopreserved sample was homogenized in liquid nitrogen by using pestle and mortar. One gram of the powdered samples was mixed with 2 ml saturated NaCl in a 20 ml-head-space vial, in which an internal standard (10 μl of 8.08 mg /L 2,6-dimethyl-4-heptanone (cat. Nr. W353701 from Sigma–Aldrich, Shanghai, China) was added. Before subjecting the mixtures for SPME extraction, each vial was heated at 60 ◦ C for 10 min. Subsequently, the headspace of the sample vial was exposed to a 65 μm divinylbenzene/carboxen/polydimethylsilioxan fiber (Supelco, Bellefonte, PA, USA) for 20 min at 60 ◦ C to complete the extraction. Relative abundance of the compounds was quantified by peak area determination and normalized to the mass of the internal standard. We pooled samples from three plants for one biological replication and the experiment was performed twice which gave similar results. Data are shown as mean without significant test in the Results section.Published as part of Mehmood, Nasir, Yuan, Yuan, Ali, Mohammed, Ali, Muhammad, Iftikhar, Junaid, Cheng, Chunzhen, Lyu, Meiling & Wu, Binghua, 2021, Early transcriptional response of terpenoid metabolism to Colletotrichum gloeosporioides in a resistant wild strawberry Fragaria nilgerrensis, pp. 1-12 in Phytochemistry (112590) (112590) 181 on page 7, DOI: 10.1016/j.phytochem.2020.112590, http://zenodo.org/record/829067
On My Way: Optimizing Driving Routes for Navigation Applications
No full textConventionally, the route recommendations given by GPS navigation applications have been considered as the optimal route search problem only between two locations - origin and destination. Sometimes people want to visit several intermediate locations prior to reaching their final destination. For example, travelers may want to visit a diner and a gas station before arriving at their vacation destination. Although there is likely to be many choices that are available along the route to the destination, only one place from each type should be chosen. Furthermore, in new emerging application domains, such as “physical-world crowdsourcing”, people may want to opportunistically visit some places in order to complete personal or work related tasks. Our work explores a design space where we try to reduce the amount of requests made to third-party map and route data providers. We explore the simple idea of using the Euclidean distance as a rough estimate for the optimal route between destinations with multiple waypoints. Our preliminary results indicate that with over 80% of test cases, this simple Euclidean distance estimator approach gives at least one optimal routing alternative.Yuan, Fengpeng, Song, Xueyuan & Lindqvist, Janne.

Tunable acoustic attenuation in dilute suspensions of non-spherical magnetic particles
No full textThe microstructure of suspensions of ferromagnetic particles with subwavelength size can be controlled by an external field, making it possible to develop novel broadband acoustic materials with anisotropic and tunable acoustic properties. In this study we experimentally show that dilute suspensions of nickel micro-flakes exhibit a greater than 20% change in attenuation coefficient at MHz frequencies upon changing the direction of an external magnetic field, at particle volume fractions of only 0.5%. Optical transmission measurements and analysis of the characteristic timescales of particle alignment and chaining are used to study the mechanisms behind this acoustic anisotropy. By making comparison to suspensions of spherical particles, we show that the shape and orientation of the nickel micro-flakes play important roles in the tunable acoustic attenuation of these suspensions.Peer reviewed
