description: Paul traps are used in many different fields of physics to contain ions for different purposes. Give the oscillating fields that this type of trap employs to trap an ensemble and the heating that the interactions of these fields with multiple ions can cause, cooling the system could be of great interest, and there are several methods of doing so. This study explores on of these methods, evaporative cooling, applied to a type of Paul trap, a Linear Paul Trap (LPT), using computer simulations. This thesis will first describe a trapped ion ensemble and an evaporation event both physically and how it is computationally modeled. IT then proceeds to discuss the conditions for which evaporative cooling applied to an LPT could be optimized to maximize the chances of achieving highest temperature per particle evaporated.

Interstellar gas within $\sim 10$ pc of Sgr A$^*$
Creators: name: Ferriere, Katia
Publisher: name: arXiv
Year: 2012
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We seek to obtain a coherent and realistic three-dimensional picture of the interstellar gas out to about 10 pc of the dynamical center of our Galaxy, which is supposed to be at Sgr A$^*$. We review the existing observational studies on the different gaseous components that have been identified near Sgr A$^*$, and retain all the information relating to their spatial configuration and/or physical state. Based on the collected information, we propose a three-dimensional representation of the interstellar gas, which describes each component in terms of both its precise location and morphology and its thermodynamic properties. The interstellar gas near Sgr A$^*$ can represented by five basic components, which are, by order of increasing size: (1) a central cavity with roughly equal amounts of warm ionized and atomic gases, (2) a ring of mainly molecular gas, (3) a supernova remnant filled with hot ionized gas, (4) a radio halo of warm ionized gas and relativistic particles, and (5) a belt of massive molecular clouds. While the halo gas fills $\approx 80%$ of the studied volume, the molecular components enclose $\approx 98%$ of the interstellar mass.

description: The equine conceptus presents an extensive mobile stage from days 9 to 16 after ovulation, during which it becomes fixed to one of the uterine horns. Throughout mobility, the conceptus secretes fibrinogen (an integrin-binding ECM). We hypothesized that conceptus-derived fibrinogen is converted into fibrin and aids in fixation via integrin receptors. We determined that RGD-binding integrins are expressed in endometrial and embryonic/fetal cells and interact with fibrinogen. Moreover, endometrial and embryonic cells presented the machinery to convert fibrinogen into fibrin and maintain the fibrin network. Overall, we demonstrated that conceptus-derived fibrinogen is likely converted to fibrin at the embryo-maternal interface and mediates cell adhesion via RGD-binding integrins.

description: We investigate the $Λ(1520)$ photoproduction in the $\vecγ p \to K^+ Λ(1520)$ reaction within the effective Lagrangian method near threshold. In addition to the "background" contributions from the contact, $t-$channel $K$ exchange, and $s-$channel nucleon pole terms, which were already considered in previous works, the contribution from the nucleon resonance $N^*(2080)$ (spin-parity $J^P = 3/2^-$) is also considered. We show that the inclusion of the nucleon resonance $N^*(2080)$ leads to a fairly good description of the new LEPS differential cross-section data, and that these measurements can be used to determine some of the properties of this latter resonance.

description: The world is facing problems of the increasing amount of resources wasted as the world population grows. Biowaste streams form a significant part of the overall waste generation, and a circular economy utilizing this biowaste will significantly reduce waste whilst lowering the anthropogenic carbon footprint. Due to their energy content and high concentration of hydrocarbon molecules, bio-based waste streams have the potential to be transformed into valorized products (energy, fuels, and chemicals) using biorefinery technologies. In this work, a mini-review has been conducted on available, mostly European databases on existing biomass types and biorefinery technologies to provide a framework for a desirable, comprehensive database connecting bio-based waste streams, biorefinery technologies and bioproducts, as well as the geographical distribution of feedstocks and biorefineries. The database assessment utilized the SWOT (strengths, weakness, opportunities, threats) methodology to support benchmark analysis and to identify critical gaps in underlying data structures that could be included in a single database. The results show that current databases are useful but insufficient for waste biorefineries due to limited quality and quantity as well as the usability of data. A comprehensive database or improved database cluster would be necessary, not only for technology development but for better investment and policy decisions. The development of the new database architecture would need to incorporate the aspects: expansion of database scope and content depth, improved usability, accessibility, applicability, update frequency, openness to new contributions, process descriptions and parameters, and technology readiness level.
Praise, Patronage, and the Penshurst Poems: From Jonson (1616) to Southey (1799)

description: The Penshurst group of poems (1616-1799) is a collection of twelve poems—beginning with Ben Jonson’s country-house poem “To Penshurst”—which praises the ancient estate of Penshurst and the eminent Sidney family. Although praise is a constant theme, only the first five poems praise the respective patron and lord of Penshurst, while the remaining poems praise the exemplary Sidneys of bygone days, including Sir Philip and Dorothy (Sacharissa) Sidney. This shift in praise coincides with and is largely due to the gradual shift in literary economy: from the patronage system to the literary marketplace. Instead of obligatory laudatory works for aristocratic patrons, print culture offered writers new opportunities and literary authority: poets praised subjects they felt worthy and commercial readers found fashionable. The De L’Isle and Sidney Manuscripts—located in the Kent History and Library Centre—has provided this study with new and invaluable information regarding praise, patronage, and Penshurst.

As we show, it is not uncommon that some studies on the nature of dark matter include extra assumptions, some even on the very nature of the dark matter, what we want to determine!, and that bias the studies and the results obtained from the observation and, in some cases, imply an inconsistent system altogether.

description: Successful activities in the Eagle Ford shale in Texas through drilling of horizontal wells and completions using multi-stage hydraulic fracturing jobs suggest that the potential of shale reservoirs south of the border will be quite significant. This observation leads to the objective of this study: to integrate available geoscience and engineering data to evaluate the potential of Mexican shales, and their oil and gas endowment under different oil and gas prices scenarios. Endowment is defined by the United States Geological Survey (USGS, 2010) as the sum of known volumes of oil and gas (cumulative production plus remaining reserves) and undiscovered volumes. Emphasis is placed on the Upper Cretaceous Eagle Ford shale and the Upper Pimienta shale in Burgos basin, located just south of the border with Texas (United States). Other shales considered in this study are found in the Sabinas, Tampico, Tuxpan (Platform), Veracruz and Chihuahua basins throughout Mexico. The economic potential of these plays is examined with the use of cumulative long run supply (or availability) curves. It is concluded that the potential of unconventional resources in Mexico is quite significant and will help to change the slope of production rates in the country from negative to positive. As a result, it is anticipated that Mexico will become an important part of the shale petroleum revolution initiated in the United States.

description: The proximity of core-collapse Supernova 1987A (SN1987A) in the Large Magellanic Cloud (LMC) and its rapid evolution make it a unique case study of the development of a young supernova remnant. We aim at resolving the remnant of SN1987A for the first time in the 3-mm band (at 94 GHz). We observed the source at 3-mm wavelength with a 750-m configuration of the Australia Telescope Compact Array (ATCA). We compare the image with a recent 3-cm image and with archival X-ray images. We present a diffraction-limited image with a resolution of 0.7", revealing the ring structure seen at lower frequencies and at other wavebands. The emission peaks in the eastern part of the ring. The 3-mm image bears resemblance to early X-ray images (from 1999-2000). We place an upper limit of 1 mJy (2 σ) on any discrete source of emission in the centre (inside of the ring). The integrated flux density at 3 mm has doubled over the six years since the previous observations at 3 mm. At 3 mm - i.e. within the operational domain of the Atacama Large Millimeter/submillimeter Array (ALMA) - SN1987A appears to be dominated by synchrotron radiation from the inner rim of the equatorial ring, characterised by moderately-weak shocks. There is no clear sign of emission of a different nature, but the current limits do not rule out such component altogether.

description: Bioethanol is a renewable fuel widely used in road transportation and is generally regarded as a clean energy source. Although fermentation is one of the major processes in bioethanol production, studies on improving its efficiency through operational design are limited, especially compared to other steps (pretreatment and hydrolysis/saccharification). In this study, two adapted feeding strategies, in which feed medium addition (sugar delivery) was adjusted to increase the supply of fermentable sugar, were developed to improve ethanol productivity in 5-L fed-batch fermentation by Saccharomyces cerevisiae. Specifically, a linear adapted feeding strategy was established based on changes in cell biomass, and an exponential adapted feeding strategy was developed based on cell biomass accumulation. By implementing these two feeding strategies, the overall ethanol productivity reached 0.88±0.04 and 0.87±0.06 g/L/h, respectively. This corresponded to ~20% increases in ethanol productivity compared to fixed pulsed feeding operations. Additionally, there was no residual glucose at the end of fermentation, and final ethanol content reached 95±3 g/L under the linear adapted operation and 104±3 g/L under the exponential adapted feeding strategy. No statistical difference was observed in the overall ethanol yield (ethanol-to-sugar ratio) between fixed and adapted feeding strategies (~91%). These results demonstrate that sugar delivery controlled by adapted feeding strategies was more efficient than fixed feeding operations, leading to higher ethanol productivity. Overall, this study provides novel adapted feeding strategies to improve sugar delivery and ethanol productivity. Integration into the current practices of the ethanol industry could improve productivity and reduce production costs of fermentation processes.

description: This thesis argues that Wollstonecraft’s ten-year writing career can be divided into three distinct periods of time. In the (1787-1788), when she was a regular attendant at the Church of England and influenced by Anglican Trinitarianism, she published a book on education and a novel while living and teaching in Newington Green, London. The middle period (1789-1992) details her career as a professional writer in London and a member of Joseph Johnson’s circle of political and religious Dissenting radicals. Wollstonecraft became a celebrated figure in history as a result of A Vindication of the Rights of Woman (1792). During late stage of Wollstonecraft’s writing career (1793-1797), she became disillusioned with rational Dissenters, after she witnessed the French Revolution’s Reign of Terror, had a failed relationship and an illegitimate daughter, and travelled to Scandinavia, where she expressed her religious beliefs through a more distant and abstract Romantic Deism. I will examine the changing religious influences that impacted her writing: from Anglicanism, to Radical Dissent, and Romantic Deism.

description: To enhance the aromas in Guangdong rice-flavor Baijiu, ester-producing yeast was selected to fortify Baijiu brewing. Among eight kinds of ester-producing yeasts selected, Saccharomyces cerevisiae CM15 (CM15) that showed both the stronger ability to utilize substrates to produce esters and the excellent tolerance to industrially relevant stress factors was chosen. When CM15 was synergistically fermented with six kinds of Kojis from distilleries of rice-flavor liquor in Guangdong, the enhanced total esters had happened to the liquors brewing with the fortified four kinds of Kojis, especially with Koji F. When Koji F was fortified with CM15, the resultant Baijiu showed a higher esters proportion and a lower higher alcohol ratio than that of Baijiu brewed only with Koji F, with the content of ethyl acetate and ethyl lactate increasing by 25% and 214%, respectively. This study suggested that CM15 can be used as a functional microorganism to fortify Baijiu brewing, which might also be suitable for other traditional fermented foods.

description: Therapeutic strategies for non-small cell lung cancer (NSCLC), such as platinum-based antineoplastic therapies (platins), generate DNA breaks and stimulate DNA damage response pathways. A key component of the response to DNA damage is the protein ataxia telangiectasia mutated (ATM). Evidence from the Glans-Look Database suggests that patients with low tumour ATM protein expression have improved disease-free survival rates after adjuvant platin therapy. I hypothesize that ATM-deficient tumours will be innately sensitive to platin therapies. NSCLC cell lines were treated with increasing concentrations of platins and assessed for ATM activation. ATM knockdown cell lines were generated using shRNA and investigated for cisplatin sensitivity. ATM-proficient cell lines demonstrated increased levels of phosphorylated-ATM in response to platins. ATM knockdowns had increased sensitivity to IR and a trend toward increased sensitivity to cisplatin. It is evident that platin exposure induced an ATM mediated signaling, however the predictive capabilities for ATM-loss to platin sensitivity is still unclear.

description: A recently strategy applied to anaerobic digestion (AD) is the use of biochar (BC) obtained from the pyrolysis of different organic waste. The PRISMA protocol-based review of the most recent literature data from 2011–2022 was used in this study. The review focuses on research papers from Scopus® and Web of Knowledge®. The review protocol used permits to identify 169 articles. The review indicated a need for further research in the following challenges on the application of BC in AD: i) to increase the use of BC in developing countries, which produce large and diverse amounts of waste that are the source of production of this additive; ii) to determine the effect of BC on the AD of organic waste under psychrophilic conditions; iii) to apply tools of machine learning or robust models that allow the process optimization; iv) to perform studies that include life cycle and technical-economic analysis that allow identifying the potential of applying BC in AD in large-scale systems; v) to study the effects of BC on the agronomic characteristics of the digestate once it is applied to the soil and vi) finally, it is necessary to deepen in the effect of BC on the dynamics of nitrogen and microbial consortia that affect AD, considering the type of BC used. In the future, it is necessary to search for new solutions in terms of the transport phenomena that occurs in AD with the use of BC using robust and precise mathematical models at full-scale conditions.

description: Antibody–drug conjugates (ADCs) can improve therapeutic indices compared to plain monoclonal antibodies (mAbs). However, ADC synthesis is complex because the components are produced separately in CHO cells (mAb) and often by chemical synthesis (drug). They are individually purified, coupled, and then the ADC is purified, increasing production costs compared to regular mAbs. In contrast, it is easier to produce recombinant fusion proteins consisting of an antibody derivative, linker and proteinaceous toxin, i.e. a recombinant immunotoxin (RIT). Plants are capable of the post-translational modifications needed for functional antibodies and can also express active protein toxins such as the recombinant mistletoe lectin viscumin, which is not possible in prokaryotes and mammalian cells respectively. Here, we used Nicotiana benthamiana and N. tabacum plants as well as tobacco BY-2 cell-based plant cell packs (PCPs) to produce effective RITs targeting CD64 as required for the treatment of myelomonocytic leukemia. We compared RITs with different subcellular targeting signals, linkers, and proteinaceous toxins. The accumulation of selected candidates was improved to ~ 40 mg kg−1 wet biomass using a design of experiments approach, and corresponding proteins were isolated with a purity of ~ 80% using an optimized affinity chromatography method with an overall yield of ~ 84%. One anti-CD64 targeted viscumin-based drug candidate was characterized in terms of storage stability and cytotoxicity test in vitro using human myelomonocytic leukemia cell lines. We identified bottlenecks in the plant-based expression platform that require further improvement and assessed critical process parameters that should be considered during process development for plant-made RITs. Toxin type and domain sequence affect accumulation of recombinant immunotoxins.Transient expression in plant cell packs and intact plants correlates well.IC50 values of toxicity correlate with the cell surface receptor concentration Toxin type and domain sequence affect accumulation of recombinant immunotoxins.

description: We investigate cosmological scenarios in the theory of gravity with the scalar field possessing a non-minimal kinetic coupling to the curvature. It is shown that the kinetic coupling provides an essentially new inflationary mechanism. Namely, at early cosmological times the domination of coupling terms in the field equations guarantees the quasi-De Sitter behavior of the scale factor: $a(t)\propto e^{H_κ t}$ with $H_κ=1/\sqrt{9κ}$, where $κ\simeq 10^{-74}$ sec$^2$ is the coupling parameter. The primary inflationary epoch driven by non-minimal kinetic coupling comes to the end at $t_f \simeq 10^{-35}$ sec. Later on, the matter terms are dominating, and the universe enters into the matter-dominated epoch which lasts approximately $0.5H_0^{-1}\sim 0.5\times10^{18}$ sec. Then, the cosmological term comes into play, and the universe enters into the secondary inflationary epoch with $a(t)\propto e^{H_Λ t}$, where $H_Λ=\sqrt{Λ/3}$. Note that the present value of the acceleration parameter $q=\ddot a a/\dot a^2$ is estimated as $q_0\simeq0.25$, that is the universe is at the beginning of the epoch of accelerated expansion. Thus, the cosmological model non-minimal kinetic coupling represents the realistic cosmological scenario which successfully describes basic cosmological epochs and provide the natural mechanism of epoch change without any fine-tuned potential.

description: We study a frustrated quantum Ising model relevant for Ca$_3$Co$_2$O$_6$ that consists of a triangular lattice of weakly-coupled ferromagnetic (FM) chains. According to our quantum Monte Carlo simulations, the chains become FM and form a three-sublattice "up-up-down" structure for $T \leq T_\text{CI}$. In contrast, long-period spin-density-wave (SDW) {\it microphases} are stabilized along the chains for $T_\text{CI} < T < T_c$. Our mean field solutions reveal a quasi-continuous temperature dependence of the SDW wavelength, implying the existence of metastable states that explain the very slow dynamics observed in Ca$_3$Co$_2$O$_6$. We also discuss implications of microphases for the related multiferroic compounds Ca$_3$CoMnO$_6$ and Lu$_2$MnCoO$_6$.

description: We study the stellar cluster population in two adjacent fields in the nearby, face-on spiral galaxy, M83, using WFC3/HST imaging. The clusters are selected through visual inspection to be centrally concentrated, symmetric, and resolved on the images, which allows us to differentiate between clusters and likely unbound associations. We compare our sample with previous studies and show that the differences between the catalogues are largely due to the inclusion of large numbers of diffuse associations within previous catalogues. The luminosity function of the clusters is well approximated by a power-law with index, -2, over most of the observed range, however a steepening is seen at M_V = -9.3 and -8.8 in the inner and outer fields, respectively. Additionally, we show that the cluster population is inconsistent with a pure power-law mass distribution, but instead exhibits a truncation at the high mass end. If described as a Schechter function, the characteristic mass is 1.6 and 0.5 * 10^5 Msun, for the inner and outer fields, respectively, in agreement with previous estimates of other cluster populations in spiral galaxies. Comparing the predictions of the mass independent disruption (MID) and mass dependent disruption (MDD) scenarios with the observed distributions, we find that both models can accurately fit the data. However, for the MID case, the fraction of clusters destroyed (or mass lost) per decade in age is dependent on the environment, hence, the age/mass distributions of clusters are not universal. In the MDD case, the disruption timescale scales with galactocentric distance (being longer in the outer regions of the galaxy) in agreement with analytic and numerical predictions. Finally, we discuss the implications of our results on other extragalactic surveys, focussing on the fraction of stars that form in clusters and the need (or lack thereof) for infant mortality.

Biomechanical Measures of the Muscle-Bone Unit in Postmenopausal Females: A Pilot Study

Publisher: name: Graduate Studies

Subjects: Engineering--Biomedical

description: Bone is a dynamic tissue that adapts its stiffness and strength to the habitual loading environment. Muscles attach to bone and the largest loads experienced by bone come from voluntary muscle contractions. The objective of this study was to quantify the relationship between functional measures of muscle loading (i.e., joint moments, isometric muscle strength, and physical activity questionnaire scores) and bone stiffness, strength, and volumetric bone mineral density (vBMD). Moderate correlations were observed between peak joint moments and bone stiffness (r=0.480, p=0.032) and strength (r=0.490, p=0.028). No relationship was observed between joint moments and vBMD, or between any bone measurements and muscle strength or physical activity. These findings suggest that muscle loading may influence bone stiffness and strength through alterations in bone quality rather than quantity, and that the functional relationship between muscle and bone may be best reflected by habitual measures of skeletal loading.

description: Cancer is a disease that impacts not only the patient, but also the family. Family members often take on the caregiving role and provide much needed emotional support, instrumental support, help with medical decision making, and physical care when their loved one has cancer. The care that is provided by family members is also an important resource to the cancer care system, when most treatments are delivered in an outpatient setting. While benefitting the cancer care system and providing much needed support to their family member, family caregiving may be detrimental to caregivers’ own physical and psychological health. Research over the last 30 years has documented the many negative impacts of caregiving and has highlighted the need for more studies focused on improving caregivers self-care and physical health. The purpose of this doctoral research was to examine the role of physical activity in supporting health and wellbeing in family caregivers to adult cancer patients. A systematic review was first conducted to synthesize and critically evaluate the evidence for physical activity interventions in family caregivers. Next, a cross sectional survey was conducted to evaluate physical and psychological health, and to assess current levels of, as well as barriers and motivations to physical activity, in men and women caregivers. A randomized controlled trial was then designed and implemented and mixed methods where used to evaluate outcomes on physical health, psychological health, and physical fitness. Findings from this research demonstrate there is a role for physical activity in supporting caregiver health and wellbeing. The results from our randomized controlled trial demonstrated improvements to mental well-being, physical activity levels, and physical fitness. Given some of the caregivers in our survey, and the majority in the randomized control trial, had high levels of depression, anxiety, and poor mental health quality of life, improvements to mental wellbeing through physical activity adds important new evidence about mechanisms to support caregivers. Ongoing work to further examine mechanisms to support caregiver health and wellbeing, and how to effectively deliver sustainable programs, is imperative as caregivers will continue to be relied upon by patients and the cancer care system into the future.

description: Spinal cord injuries (SCIs) are commonly studied experimentally by causing injury to rodent spinal cords in vivo and analyzing behavioral and histological results post injury. Few researchers have directly investigated the deformation of the in vivo spinal cord during impact, which is thought to be a predictor of injury. This knowledge would help to establish correlations among impact parameters, internal structure deformation, and histological and functional outcomes. The objective of this thesis was to develop a radiographic method of tracking the real-time internal deformations of an anesthetized rat‘s spinal cord during a typical experimental SCI. A technique was developed for injecting fiducial markers into the dorsal and ventral white and grey matter of in vivo rat spinal cords. Two radio-opaque beads were injected into C5/6 in the approximate location of the dorsal and ventral white matter. Four additional beads were glued to the surface of the cord caudal and cranial to the injection site (one dorsal, one ventral). Overall bead displacement was measured during quasi-static compression using standard medical x-ray equipment. Dynamic bead displacement was tracked during a dorsal impact (130mm/s, 1mm depth) by imaging laterally at 3,000 fps using a custom high-speed x-ray system. The internal spinal cord beads displaced 1.02-1.7 times more than the surface beads in the cranial direction and 2.5-11 times more in the ventral direction for the dynamic impact and maximum quasi-static compressions. The dorsal spinal cord beads (internal and surface) displaced more than the ventral spinal cord beads during all compressions. Finite element modeling and experimental measurements suggested that bead migration with respect to the spinal cord tissue was small and mostly insignificant. These results support the merit of this technique for measuring in vivo spinal cord deformation. The differences in bead displacements imply that the spinal cord undergoes complex internal and surface deformations during impact. Many applications of this technique are conceivable including validating finite element and surrogate models of the spinal cord, comparing localized grey and white matter motion during impact to histological findings, and improving SCI preventative and treatment measures.

description: This article reviews recent historical investigations of transitional trials held after the Second World War. It identifies three main strands of historiography. One group of studies has been dominated by the trials' participants who have shaped the perception of the trials' scope, their achievements, and their shortcomings, and pursued political, legal, or biographical agendas. A second group has treated the trials as a mere epilogue to the history of the deceased regimes. A third, more profound approach has conceptualized the trials as places where collective memory was assembled, configured, and shaped. This notion opens the debate to an analysis of how law and history on the one hand, jurisdiction, jurisprudence, and historiography on the other interact and how they impact on one another. The article compares and evaluates the benefits drawn from this research. It finds that historical analyses which take seriously the epistemological premises of the law as well as the courtroom's performativity manage to bypass well-trodden paths of interpretation which either deplore the limited, inadequate punishment meted out, or celebrate the triumphant march from Nuremberg to The Hague. The article concludes that such interdisciplinary readings help to avoid widespread disillusionment with the results of transitional trials.
Pupils' choices and social mobility after the Thirty Years War: A quantitative study

description: This article presents the main findings of the first detailed reconstruction of the pattern of attendance at an early modern German school, based on the exceptionally preserved matriculation records of the Latin (grammar) school of Zwickau/Saxony in the second half of the seventeenth century. It investigates pupils’ social background, their geographical mobility, and reconstructs their educational choices. Prevailing top-down perspectives on early modern education obscure the range of choices available to pupils. This article argues that substantial social mobility into learned professions formed the backdrop to the preoccupation with rank and distinction within the Republic of Letters in the Holy Roman Empire.

description: This thesis considers the development of a proposed pipeline monitoring approach based on acoustic measurements of a pipe. Relationship between the acoustics generated by a turbulent pipeline and the flowrate is examined to understand the physical behaviour of the phenomenon and verify assumptions. A framework is developed to extract features from the flow acoustics in offline and real-time settings for continuous monitoring. To ensure these features are suitable for modelling a flow-acoustic correlation, deep learning and empirical models are compared from experimental measurements of turbulent pipe flows. For deeper insight to turbulent flows, the spatio-temporal dynamics of the flow and acoustics are presented. Empirical dynamic models are shown to predict the dynamics of turbulent flow. The results show experimental evidence of ordered structures in turbulence captured in the acoustics. By isolating these structures, the turbulent motion can be predicted.

description: Face au vieillissement de la population (OFS 2007) et l’augmentation des coûts de santé (OMS 2016) une réponse politique est nécessaire. La réduction de la durée d’hospitalisation (Obsan, 2018) avec le développement des soins à domicile en est une. Ces traitements représentent un défi nouveau pour les soins infirmiers (Brunner & Suddarth, 2015). Les maladies cardiovasculaires (MCV), dont fait partie l’Insuffisance Cardiaque (IC), sont la première cause de décès dans le monde (Organisation Mondiale de la Santé (OMS), 2017) et la troisième cause d’hospitalisation en Suisse (Office Fédéral des Statistiques (OFS), 2015). 12% des hospitalisations pour MCV des 65-85 ans sont liées à l’insuffisance cardiaque. Celle-ci est donc considérée comme une problématique de santé majeure ayant de nombreuses conséquences sur la qualité de vie des patients.

description: Low dimensional structures have demonstrated improved thermoelectric (TE) performance because of a drastic reduction in their thermal conductivity, κl. This has been observed for a variety of materials, even for traditionally poor thermoelectrics such as silicon. Other than the reduction in κl, further improvements in the TE figure of merit ZT could potentially originate from the thermoelectric power factor. In this work, we couple the ballistic (Landauer) and diffusive linearized Boltzmann electron transport theory to the atomistic sp3d5s*-spin-orbit-coupled tight-binding (TB) electronic structure model. We calculate the room temperature electrical conductivity, Seebeck coefficient, and power factor of narrow 1D Si nanowires (NWs). We describe the numerical formulation of coupling TB to those transport formalisms, the approximations involved, and explain the differences in the conclusions obtained from each model. We investigate the effects of cross section size, transport orientation and confinement orientation, and the influence of the different scattering mechanisms. We show that such methodology can provide robust results for structures including thousands of atoms in the simulation domain and extending to length scales beyond 10nm, and point towards insightful design directions using the length scale and geometry as a design degree of freedom. We find that the effect of low dimensionality on the thermoelectric power factor of Si NWs can be observed at diameters below ~7nm, and that quantum confinement and different transport orientations offer the possibility for power factor optimization.
