Hitchhiking Through the Fire
Ten years after the outbreak of an aggressive, fast-acting virus that kills then reanimates those infected, the world has become a bleak, hostile place. Water and food are scarce, valuable commodities, and survivors cluster together for safety in isolated enclaves where life is cheap and debauchery …

Macrophage-hitchhiking Anisotropic Microparticles for Therapeutic and Diagnostic Applications
Cell therapies represent a major paradigm shift of biotechnology in medicine due to its transformative potential in treating previously incurable diseases. A variety of cells have been applied for cell therapies, including stem cells, tissue-specific cells, and hematopoietic cells. Particularly, …

Trek : hitchhiking on the ox-wagon of destiny : voortrekker, draadtrekker, saamtrekker
As a South African artist I am in power to influence some manner of change, through my art, to the structure of national thought and hence national identity. Through my live art installation TOTANDERKUNTUlT, I offered South Africans the opportunity to engage in the cathartic process of resolution …

Evolutionary Instability Of Genomic Mutation Rate In Rapidly Adapting Asexual Mutator Escherichia Coli Populations
… populations through a process called ‘mutator hitchhiking’. Theory predicts that repeated mutator hitchhiking can occur in an adapting asexual mutator population. I tested this prediction in two settings: a mutL- population under lethal selection and a mutS- population under soft selection. In …

How to Hitchhike West with a Promise
… journey of the main character, Charlie, who is hitchhiking from the Chicago suburbs to California in order to spread his mother’s ashes. It takes inspiration from the traditional American road trip novels, while following a contemporary narrative that dives into the main character’s judgmental …

Lysosomes and Ribonucleoprotein Dynamics in Neurons
… We find that ANXA11 enables RNA granule hitchhiking on motile lysosomes, promoting the long-distance transport of RNA within neuronal processes. Critically, disease-linked mutations in ANXA11 disrupt this transport, providing support for failed RNA transport as a pathogenic mechanism in …

IoT Networking via Cross-technology Communication
… of bandwidth disparity, XFi adopts signal hitchhiking - low-speed IoT packets from ZigBee and LoRa devices can hitchhike on the high-speed Wi-Fi traffic and be captured by Wi-Fi radios. The unique discovery is that Wi-Fi devices can obtain the hitchhiking IoT data from the errors in decoded …

Studying Mechanisms of Ionizing Radiation Resistance in Bacteria: Evidence for Multiple Pathways
… evolutionary phenomena: clonal interference and hitchhiking suggesting that not all polymorphisms seen in the final population could contribute to IR resistance. The analysis of population sequencing results along with the phylogenetic analysis reduced the number of potential candidates …

Pseudoscorpion Systematics & Phylogenetics: Exploring the Effects of Accelerated Rates of Evolution on Both Ancient and Recent Diversification
… light on the evolution of silk, venom, phoresy (hitchhiking), and the chelicerate body plan. The advent of molecular sequencing technologies has illuminated additional fascinating biological attributes about these animals, including abnormal mitochondrial tRNA and rRNA genes, accelerated rates of …

Identification of Deleterious and Disease Alleles in a General Population and Preterm Labor Patients
… genetic linkage with beneficial alleles by the hitchhiking effect.</p> <p>Second, I developed an integrative strategy to predict disease-causing non-coding variants in FSH receptor, a gene known to be associated with preterm birth, as a proof of principle. I sequenced protein-coding and …

Optimal Task Scheduling and Flight Planning for Multi-Task Unmanned Aerial Vehicles
… recharging at a roadside charging station, or hitchhiking and recharging on a collaborative vehicle. The objective is to minimize the energy consumption of the UAV and ensure timely delivery. We reveal the conditions under which the UAV’s flight planning changes in terms of the remaining flight …

Attachment of fibrous materials in nature and surgical repair
… to spread their fruit more successfully via “hitchhiking” onto the fur or socks of passing animals. Using judiciously and biomimetically chosen sutures and suture spacing may halve the peak stresses that arise at a sutured reattachment of tendon to bone. The dissertation continues with the …

Origin, evolution, and global spread of a transmissible cancer clone
… insights into biological mechanisms driving the hitchhiking cancer that has accompanied them around the world.

A Hitchhiker’s Guide to Invasion Biology: Describing the Ecological Mechanisms Underlying the Range Expansions of Two Ixodid Tick Species
… organisms that disperse across landscape by hitchhiking on hosts, but must then survive in the environment for long periods of time between bloodmeals. Two species of ixodid tick, Ixodes affinis and Amblyomma maculatum, are simultaneously expanding their ranges throughout the Mid-Atlantic …

Collective Evolution of Biological and Physical Systems
… patterns are expected, due to genetic drift or hitchhiking of slightly deleterious adjustments of the translational system on other beneficial traits. Then, I show that the above coevolutionary dynamics provides an efficient mechanism for optimization of genetic codes, even if, as the frozen …

Quantitative Analyses of Normal and Precancerous Somatic Evolution in Human Tissues
Cancer arises from a single cell of origin whose lineage accumulates somatic mutations in a step-wise manner over time. The evolutionary process towards cancer development is dynamic and the earliest mutation may arise decades before the onset for some cancers. This calls for a quantitative …
