title: Theaetetus and the Making of a Philosopher: Character and the Nature of Philosophical Discussion in Plato's Theaetetus

description: Traditional approaches to Plato’s Theaetetus have it that it is only, or at least primarily, about knowledge. Yet large sections of the dialogue, including the so-called “Digression” of 172c-177c, do not appear to be concerned with knowledge at all, but with the nature of the philosopher and the activity the philosopher engages in, i.e. philosophical discussion. I offer a reading of the Theaetetus that proceeds from the assumption that the inclusion of such material suggests that the dialogue is also about philosophy and the philosopher, and I find such concerns in fact present throughout both explicitly and implicitly. On my view, the dialogue is both dramatically and philosophically a portrayal of the philosophical progress of Theaetetus, whose first encounter with philosophical discussion, when Socrates asks him if he can help find what knowledge is, not only demonstrates that he has, but draws out and develops in him, an essentially philosophical character – where to be “philosophical” is much more than to just be adept with arguments or quick to come up answers to philosophical questions, but to be willing to try out answers to such questions without attachment to them, to learn from the shortcomings of previous attempts, and ultimately to have a certain kind of orientation toward the world.

description: Centralized crypto exchange (CEX) platforms offer to eliminate the technical barriers to crypto adoption. But how has an industry ostensibly committed to decentralization come to rely on such centralized entities? The literature analyzing CEX platforms through a political economy lens is sparse, and as crypto grows and becomes more interconnected with the traditional finance system, deeper understanding is required. This study explores how centralized CEX platforms (Binance, FTX, and Coinbase) mediate the promises of crypto through the financialization and regulatory logics of platform power, in the context of the entangled technology and venture capital industries. I construct a theoretical framework of platform power framework that captures a set of analytical perspectives on platforms, and I employ a modified stack economization model as a tool to enable a platform power political economic analysis. My findings demonstrate that CEX platforms extract and transform the original visions for crypto to produce the current promise of crypto prototype. They eclipse the neoclassical conception of the market and instead constitute stacked opportunities for financialization, where CEX platform power manifests in power asymmetries premised upon recentralization and extraction. In so doing, CEXs leverage neoliberal discursive strategies in their policy advocacy. Based on these findings, I argue that CEX platforms deploy the promise of crypto prototype to accumulate, benefit from, and perpetuate platform power.

description: We study the interplay of superfluidity and glassy ordering of hard core bosons with random, frustrating interactions. This is motivated by bosonic systems such as amorphous supersolid, disordered superconductors with preformed pairs, and helium in porous media. We analyze the fully connected mean field version of this problem, which exhibits three low-temperature phases, separated by two continuous phase transitions: an insulating, glassy phase with an amorphous frozen density pattern, a nonglassy superfluid phase, and an intermediate phase, in which both types of order coexist. We elucidate the nature of the phase transitions, highlighting in particular the role of glassy correlations across the superfluid-insulator transition. The latter suppress superfluidity down to T=0, due to the depletion of the low-energy density of states, unlike in the standard BCS scenario. Further, we investigate the properties of the coexistence (superglass) phase. We find anticorrelations between the local order parameters and a nonmonotonous superfluid order parameter as a function of T. The latter arises due to the weakening of the glassy correlation gap with increasing temperature. Implications of the mean field phenomenology for finite dimensional bosonic glasses with frustrating Coulomb interactions are discussed.

description: A TQFT is a functor from a cobordism category to the category of vector spaces, satisfying certain properties. An important property is that the vector spaces should be finite dimensional. For the WRT TQFT, the relevant 2+1-cobordism category is built from manifolds which are equipped with an extra structure such as a p_1-structure, or an extended manifold structure. We perform the universal construction of Blanchet, Habegger, Masbaum and Vogel on a cobordism category without this extra structure and show that the resulting quantization functor assigns an infinite dimensional vector space to the torus.

Youth--Legal status, laws, etc.

description: There is a growing awareness, in the United States and Europe that emerging adults – those ages 18–25 – are a developmentally distinct group worth special treatment at the hands of the justice system. Four US states have proposed raising the age of their juvenile courts’ jurisdiction beyond age 18 within the last year, while four out of five European countries have special laws affecting emerging adults. Three European nations – Croatia, Germany, and the Netherlands – allow youth over age 18 to be sanctioned in the same manner as younger youth in the juvenile justice system, including the possibility of being housed in juvenile facilities. In March 2018, the Columbia University Justice Lab sponsored an educational delegation of 20 elected and appointed officials, legal system stakeholders, service providers, and advocates to Germany to learn more about the German approach to emerging adults. In advance of that delegation, the authors in this article examined the law and practice regarding court-involved emerging adults in Croatia, Germany, and the Netherlands to glean potential lessons for US policy-makers considering a developmentally distinct approach to emerging adults in their justice systems.

description: We perform a pruning procedure on a Lévy tree and instead of throwing away the removed sub-tree, we regraft it on a given branch (not related to the Lévy tree). We prove that the tree constructed by regrafting is distributed as the original Lévy tree, generalizing a result where only Aldous's tree is considered. As a consequence, we obtain that the quantity which represents in some sense the number of cuts needed to isolate the root of the tree, is distributed as the height of a leaf picked at random in the Lévy tree.

Nursing home care

description: Background
                In the past decade, the number of long-term care (LTC) services for older adults in China has grown annually by an average of 10%. Older adults, their family members, and policymakers in China are concerned about patient outcomes in different care settings because older adults who have a similar functional status and LTC needs may choose either nursing home care or home care. The aim of this study was to compare pain perception in nursing home care and home care settings for physically dependent older adults in China.

                Methods
                Multi-stage sampling method was used to recruit respondents aged 65 and older from Yichang City, China, in 2015. The researchers employed a two-step analytical strategy—zero-inflated ordered probit regression followed by propensity score matching method—to model the effect of contrasting residence types on pain perception.

                Results
                Zero-inflated ordered probit regression analysis with participants unmatched (n = 484) showed that compared with older adults who received home care, those who received nursing home care did not have more severe pain (β = 0.088, SE = 0.196, p = 0.655). After propensity-score matching, the research found that older adults in the home care group perceived less pain compared with the nursing home group (β = 0.489, SE = 0.169, p = 0.004).

                Conclusions
                The older adults who received home care perceived significantly less pain than the nursing home residents. The pain of older adults may differ based on the type of LTC services and therapy intensity they received, and home care might lead to less pain and better comfort than nursing home care.

description: Kaposi’s sarcoma-associated herpesvirus (KSHV) was first identified in 1994 as the causative agent of the endothelial cell neoplasm, Kaposi’s sarcoma (KS). Soon after its discovery, the KSHV genome was found to code for an unusual viral RNA that was GC-rich, highly repetitive, and polycistronic, called kaposin. Kaposin is expressed during all phases of viral replication and is the most abundant viral transcript expressed in KS tumours; this makes the function of kaposin of great interest. However, in contrast to many other KSHV genes, the complex nature of kaposin impeded its study and its function during KSHV infection remains unknown. To address this, the Corcoran lab developed a set of recombinant viruses designed to eliminate kaposin protein expression both individually and in combination: ΔKapABC, ΔKapBC, ΔKapB, and ΔKapC. I describe the characterization of this set of recombinant viruses for the first time. I established cell lines stably infected with each kaposin-recombinant virus to permit their analysis, a valuable tool for the field. I used the ΔKapB virus to demonstrate that KapB, and not KapA or KapC, is required for the disassembly of cytoplasmic granules called processing bodies during KSHV infection. Unexpectedly, I found that all kaposin-recombinant viruses exhibit deficiencies in viral replication relative to the wildtype KSHV control. As each recombinant virus encodes a unique repertoire of Kap proteins, but all have an altered primary nucleotide sequence, I hypothesized that the kaposin RNA itself has biological function. My subsequent work confirms this hypothesis in two ways; first, by demonstrating that kaposin transcription leads to the formation of a three-stranded nucleotide structure called an R-loop and second, by revealing that kaposin is a viral architectural RNA that can seed and remodel cellular nuclear bodies, called nuclear speckles, to optimize viral gene expression. Taken together, my thesis work represents the first in-depth analysis of kaposin function during KSHV infection. Beyond its protein coding capacity, I have demonstrated that this singular RNA has at least two additional functions: i) R-loop formation, and ii) nuclear speckle remodeling. These findings alter the longstanding assumptions of the KSHV field and have important implications for KS-associated disease.

description: This research investigated the question: What insights can be gained from autoethnographic exploration of my experiences with reform-based science education systems in Canada, England, and the United States? Autoethnographic data was collected from recollections of my experiences teaching, researching, and leading in secondary science education over a decade (2012-2023) in three countries (Canada, England, and the United States), and presented for this research as narrative vignettes. In response to calls to capture the interplay between stakeholders and infrastructure, and to better understand and document the ways in which educational systems enact policy, I used a layered approach to analytic autoethnography to explore my experiences implementing and enacting reform-based science education. Analysis of my narrative vignettes led me to identify similarities and differences from my experiences across national and professional cultures. I discovered that while some context-dependent differences existed, robust enactment of science education across all three experiences was hindered to varying degrees regardless of infrastructural or cultural nuances. From a positioning of inbetween, I was able to capture unique insights into the innerworkings, tensions, and negotiations that took place in the third space between policy and practice from my lived experience. This research aims to increase visibility for internal intermediaries positioned in the inbetween of science education systems and to highlight autoethnography as a reliable science education research method for providing insight into the everyday ‘what is’ of science education systems in contrast to the ‘what should be’ as outlined in the aims and goals of government educational policy documents.
Structural analysis of an enterohemorrhagic Escherichia coli metalloprotease effector

Publisher: name: University of British Columbia

description: Mucins are proteins that contain dense clusters of α-O-GalNAc-linked carbohydrate chains and are the major component of the mucosal barrier that lines the mammalian gastrointestinal tract from mouth to gut. A critical biological function of mucins is to protect the underlying epithelial cells from infection. Enterohemorrhagic Escherichia. coli O157:H7 (EHEC), a bacterial pathogen that causes severe food and water borne disease, is capable of breaching this barrier and adhering to intestinal epithelial cells during infection. StcE (secreted protease of C1-esterase inhibitor) is a ~100 kDa zinc metalloprotease virulence factor secreted by EHEC and plays a pivotal role in remodelling the mucosal lining during EHEC pathogenesis. StcE also dampens the host immune response by targeting the mucinlike region of C1-INH, a key complement regulator of innate immunity. To obtain further mechanistic insight into StcE function, I have determined the crystal structure of the fulllength protease to 2.5Å resolution. This structure shows that StcE adopts a dynamic, multidomain architecture featuring an unusually large substrate binding cleft. Electrostatic surface analysis reveals a prominent polarized charge distribution highly suggestive of an electrostatic role in substrate targeting. The observation of key conserved motifs in the active site allows us to propose the structural basis for the specific recognition of α-O-glycan containing substrates, which have been confirmed by glycan array screening to be Oglycosylation of the mucin-type. Complementary biochemical analysis employing domain variants of StcE further extends our understanding of the substrate binding stoichiometry and distinct substrate specificity of this important virulence-associated metalloprotease.

Creators: name: Bowen, Kenneth
Publisher: name: Graduate Studies

Subjects: subject: Business Administration--Management

description: This thesis explores the decision behavior of individuals representing commercial and industrial companies operating in Alberta that led to the choice of a fixed-price electricity supply contract. Survey responses were received from 74 individuals and Qualitative Comparative Analysis (QCA) was employed to determine the configurations (i.e. combinations of conditions) associated with the choice of the fixed-price contract. Two meaningful configurations, each containing four conditions, were identified. The first configuration contained the unfavorable financial impact of higher prices, an expectation of the future price of electricity, the known price for the contract term, and the negative previous financial results. The second configuration comprised three of the same conditions in the first configuration, the unfavorable financial impact of higher prices, an expectation of the future price of electricity, the known price for the contract term, with the addition of the ease of retention. The desire to avoid a potentially adverse financial outcome resulting from higher future electricity prices with the certainty afforded by the fixed-price contract is suggestive of loss aversion. The additional influences of the negative previous financial results and the ease of retention indicates that generalizations of loss aversion are not as definitive as in laboratory experiments. The results of this study suggest Retail Energy Providers should concentrate their marketing efforts on evoking loss aversion to increase the contracting for the substantially higher value fixed-price product. Marketing should emphasize the risk of higher future variable prices, promote cost certainty, and encourage the ease of fixed-price re-contracting.

description: Mass-loss from evolved stars chemically enriches the ISM. Stellar winds from massive stars and their explosions as SNs shape the ISM and trigger star formation. Studying evolved stars is fundamental for understanding galaxy formation and evolution, at any redshift. We aim to establish a photometric classification scheme for Galactic mass-losing evolved stars (e.g., WR, RSG, and AGB stars) with the goal of identifying new ones, and subsequently to use the sample as tracers of Galactic structure. We searched for counterparts of known Galactic WR, LBV, RSG, and O-rich AGBs in the 2MASS, GLIMPSE, and MSX catalogs, and we analyzed their properties with near- and mid-infrared color-color diagrams. We used the Q1 parameter, which measures the deviation from the interstellar reddening vector in the J-H versus H-Ks diagram, and we defined a new parameter, Q2, that measures the deviation from the interstellar reddening vector in the J-Ks versus Ks-[8.0] diagram. The latter plane enables to distinguish between interstellar and circumstellar reddening, and to identify stars with envelopes. WR stars and late-type mass-losing stars are distributed in two different regions of the Q1 versus Ks-[8.0] diagram. A sequence of increasing [3.6]-[4.5] and [3.6]-[8.0] colors with increasing pulsation amplitudes (SRs, Miras, and OH/IRs) is found. Spectra of Miras and OH/IRs have stronger H2O absorption at 3.0um than SRs or most of the RSGs. Masing Miras have H2O, but stronger SiO (~ 4 um) and CO2 absorption (~4.25 um), as suggested by their bluer [3.6]-[4.5] colors. A fraction of RSGs (22%) have the bluest [3.6]-[4.5] colors, but small Q2 values. We propose a new set of photometric criteria to distinguish among IR bright Galactic stars. The GLIMPSE catalog is a powerful tool for photometric classification of mass-losing evolved stars. Our new criteria will yield many new RSGs and WRs.

description: We present a physically inspired model and an efficient algorithm to infer hierarchical rankings of nodes in directed networks. It assigns real-valued ranks to nodes rather than simply ordinal ranks, and it formalizes the assumption that interactions are more likely to occur between individuals with similar ranks. It provides a natural statistical significance test for the inferred hierarchy, and it can be used to perform inference tasks such as predicting the existence or direction of edges. The ranking is obtained by solving a linear system of equations, which is sparse if the network is; thus, the resulting algorithm is extremely efficient and scalable. We illustrate these findings by analyzing real and synthetic data, including data sets from animal behavior, faculty hiring, social support networks, and sports tournaments. We show that our method often outperforms a variety of others, in both speed and accuracy, in recovering the underlying ranks and predicting edge directions.

description: Background
                Adolescents treated for self-poisoning with medication have a high prevalence of mental health problems and constitute a high-risk population for self-harm repetition. However, little is known about whether this population is also prone to injuries of other forms.

                Methods
                Data were extracted from the Norwegian Patient Registry to include all incidents of treated injuries in adolescents aged 10–19 years who were treated for self-poisoning with medication during 2008–2011. This longitudinal approach allowed for the inclusion of injuries of various forms both before and after the index poisoning with medication. Gender differences and associations of injuries with recorded deliberate self-harm or psychiatric comorbidity at index poisoning were analysed. Forms of injury and psychiatric illnesses were coded according to the ICD-10 system.

                Results
                1497 adolescents treated for self-poisoning with medication were identified from the source database, including 1144 (76.4%) girls and 353 (23.6%) boys. For these 1497 adolescents a total of 2545 injury incidents were recorded in addition to the index poisoning incidents, consisting of 778 injury incidents taking place before the index poisoning and 1767 incidents taking place subsequently. Altogether 830 subjects (55.4%) had an injury treated either before or after the index poisoning. Injuries to the hand and wrist as well as injuries to the head, neck and throat were predominant in males. Females were more likely to repeat poisoning with medication, particularly those with psychiatric disorders.

                Conclusion
                Adolescents treated for poisoning with medication represent a high-risk population prone to both prior and subsequent injuries of other forms, and should be assessed for suicidal intent and psychiatric illness.

description: The psychological contract (PC) represents the mental schema an employee has about what they are obligated to provide to their organization (e.g., performing in-role duties) and what their organization is obligated to provide in return (e.g., fair pay). When employees perceive that their organization has not provided what is obligated to them and has impeded their personal goals, they experience a negative PC disruption. Negative PC disruptions are known to cause stress and negative affect and are associated with poor mental and physical health over time. However, previous theorizing and empirical investigations have under-represented the role of system dynamics in understanding how these relationships evolve over time. This dissertation describes two stand-alone papers that extend previous PC and stress theorizing through a system dynamics lens. Chapter 2 presents a theoretical integration of PC and stress dynamics and proposes a System Dynamics Model of Negative Affect and Stress, supported by 17 testable propositions. The model highlights key factors that influence the inflow (i.e., history of PC disruption, stimulus expectancies) and outflow (i.e., individual and organizational actions, outcome expectancies) of stress and negative affect and how these factors influence the experience of PC disruption over time. This model sheds light on how the PC evolves in response to changes in stress and negative affect and provides a framework for better understanding how individuals and organizations can support healthy employment relationships. Chapter 3 then presents an experimental vignette study (N = 356) that empirically tests a subset of propositions from Chapter 2. More positive outcome expectancies (compared to negative outcome expectancies) were associated with lower reports of anticipated stress and negative affect. Participants’ self- reported rumination did not appear to alter anticipated stress and negative affect across experimental blocks. Findings demonstrate the importance of employees’ beliefs about what can be done to repair the PC and encourage further exploration of factors like rumination that can alter stress and negative affect recovery. Theoretical and practical implications, as well as future research directions and challenges, are discussed.

description: Microwave imaging is a new medical imaging modality that is used to estimate and track changes in the dielectric properties (i.e. permittivity and conductivity) of tissue. It has shown promise in clinical applications like breast imaging as it is comfortable, safe and low-cost. However, due to the complexity of breast tissue a signal can travel more than one path through different tissue to get from a transmitter to a receiving antenna. This phenomenon is called multipath propagation. This work explores the potential of using multipath information to improve the permittivity estimates in microwave breast imaging. To extract the multipath information from the signals, the Hilbert-Huang Transform (HHT) was used. Data from simple simulations and phantoms with inclusions were analyzed to understand the signal shapes and patterns around an inclusion using the HHT. From these scans, multipath signals were detectable from their distinct characteristics in the time-frequency domain. From there, the signals from more complex scenarios were analysed to ensure the HHT was still effective in a realistic environment. With all these findings a signal processing algorithm was developed and applied to simulation, phantom and human data. When applied to the simulation and phantom data, the algorithm proved to be better at determining the size and permittivity of inclusions when compared to 2D projections of the models. Finally, when applied to patient data, the algorithm demonstrated strong potential to create images with improved clinical information and was useful in tracking changes in the breast tissue over time. Overall, this work demonstrated the necessity of incorporating multipath information into the signal processing algorithms of microwave imaging systems.

description: As modern networks continue to grow in scale and speed, traffic sampling has become an indispensable tool in network management. While there exists a plethora of sampling systems, they generally assume flow rates are stable and predictable over a sampling period. Consequently, when deployed in networks with dynamic flow rates, some flows may be missed or under-sampled, while others are over-sampled. This thesis presents the design and evaluation of dSamp, a network-wide sampling system capable of handling dynamic flow rates in Software-Defined Networks (SDNs). The key idea in dSamp is to consider flow rate fluctuations when deciding on which network switches and at what rate to sample each flow. We formulate the network-wide sampling with dynamic flow rates as a robust optimization problem. Our proactive approach leverages statistical information about flow rates to cope with fluctuations in flow rates. Since our initial formulation is an Integer Second Order Cone Program (ISOCP), which is infeasible for both small-scale and large-scale network instances, we shift our focus to developing an efficient approximate Integer Linear Program (ILP) called APX, which can compute sampling allocations even for large-scale networks. To show the efficacy of dSamp for network monitoring, we have implemented APX and several existing solutions in ns-3 and conducted extensive experiments using both model-driven and trace-driven simulations. Our model-driven results indicate that APX outperforms the approaches in [50] and [21] by up to 10%. Similarly, our trace-driven results show that APX surpasses these works by up to 6.37%. Unlike [50] and [21], which require fine-tuning in model-driven simulations for use in trace-driven simulations, APX works across all simulations without such a requirement.

description: Background
                Vitamin D deficiency and insufficiency have been established to be strongly associated with increased overall mortality and deaths from specific aging-related diseases. Recently, an epigenetic “mortality risk score” (MS) based on whole blood DNA methylation at the 10 most prominent mortality-related cytosine-phosphate-guanine (CpG) sites has also been found to be highly related to all-cause mortality. This study aimed to explore whether vitamin D status, defined by serum 25-hydroxyvitamin D [25(OH)D] concentrations, is associated with the MS and to what extent both indicators are individually and jointly capable of predicting all-cause mortality in a general population sample of older adults.

                Results
                The MS was derived from the blood DNA methylation profiles measured by Illumina Human Methylation 450K Beadchip, and serum 25(OH)D concentration was measured among 1467 participants aged 50–75 of the German ESTHER cohort study. There was no association between vitamin D status and the MS at baseline, but both metrics were prominently and independently associated with all-cause mortality during a median follow-up of 15.2 years. The combination of both indicators showed the potential to be a particularly strong prognostic index for all-cause mortality. Participants with vitamin D deficiency ( 5 CpG sites with aberrant methylation) had almost sixfold mortality (hazard ratio 5.79, 95% CI 3.06–10.94) compared with participants with sufficient vitamin D (≥ 50 nmol/L) and a low MS (0–1 CpG site with aberrant methylation).

                Conclusions
                This study suggests that vitamin D and the MS are strong independent predictors of all-cause mortality in older adults.

description: Abstract: Mangrove forests provide many ecosystem services but are among the world’s most threatened ecosystems. Mangroves vary substantially according to their geomorphic and sedimentary setting; while several conceptual frameworks describe these settings, their spatial distribution has not been quantified. Here, we present a new global mangrove biophysical typology and show that, based on their 2016 extent, 40.5% (54,972 km2) of mangrove systems were deltaic, 27.5% (37,411 km2) were estuarine and 21.0% (28,493 km2) were open coast, with lagoonal mangroves the least abundant (11.0%, 14,993 km2). Mangroves were also classified based on their sedimentary setting, with carbonate mangroves being less abundant than terrigenous, representing just 9.6% of global coverage. Our typology provides a basis for future research to incorporate geomorphic and sedimentary setting in analyses. We present two examples of such applications. Firstly, based on change in extent between 1996 and 2016, we show while all types exhibited considerable declines in area, losses of lagoonal mangroves (− 6.9%) were nearly twice that of other types. Secondly, we quantify differences in aboveground biomass between mangroves of different types, with it being significantly lower in lagoonal mangroves. Overall, our biophysical typology provides a baseline for assessing restoration potential and for quantifying mangrove ecosystem service provision.

description: This paper investigates higher order wave-type equations of the form $\partial_{tt}u+P(D_{x})u=0$, where the symbol $P(ξ)$ is a real, non-degenerate elliptic polynomial of the order $m\ge4$ on ${\bf R}^n$. Using methods from harmonic analysis, we first establish global pointwise time-space estimates for a class of oscillatory integrals that appear as the fundamental solutions to the Cauchy problem of such wave equations. These estimates are then used to establish (pointwise-in-time) $L^p-L^q$ estimates on the wave solution in terms of the initial conditions.

description: Bulk-shape memory alloy actuators have great potential to be used in various microdevices. Previous studies show that this material is very attractive due to its very large force, high mechanical robustness with a simple structure and biocompatibility. These properties have resulted in its commercialization for various applications including those in biomedical field. Yet their advantages have not been fully utilized. For example, the commonly used actuation mechanism using Joule heating which requires wired interfaces limits their application especially in those instances where access and space are very limited. In addition, their incompatibility with the standard MEMS fabrication process further limits their potential for use in microscale devices. This thesis presents a novel technique for the wireless control of shape-memory alloy microactuators and the method for integrating bulk-micromachined shape memory alloy material into the MEMS fabrication process. The wireless control of shape memory alloy actuators using radiofrequency magnetic field wireless heating through resonant planar coils to directly drive the actuator without the use of conditioning circuits is demonstrated. An electroplating bonding technique is developed to integrate the bulk-micromachined shape-memory alloy to the planar heater and the bonding strength is evaluated. A shape-memory alloy microgripper is fabricated and reported using developed actuation and the integration technique. Multiple actuator control is demonstrated using frequency modulated signals and its application in a form a microsyringe employing three actuators is reported. To improve the temporal response of the actuator, the wireless resonant heater circuit is fabricated using a shape-memory alloy to form an out-of-plane spiral coil which acts as the receiver coil as well as the actuator. Wireless displacement control and monitoring is also demonstrated using the fabricated device. The presented radiofrequency wireless control method also provides a platform to investigate the wireless actuation of the thermal based actuators other than the shape-memory alloy. The reported integration method also provides a means to exploit bulk materials into the MEMS fabrication process.
