description: This thesis examines the interconnected domain of energy harvesting, modular component build, and upcycling strategies in manufacturing with the goal of achieving net-zero emissions. The research is grounded in the Design for X (DFX) paradigm, which integrates various design considerations to enhance product quality while minimising environmental impact. The first part of the thesis investigates the application of radio frequency (RF) and thermoelectric generator (TEG) energy harvesting technologies in manufacturing settings. These technologies capture waste heat and electromagnetic radiation from industrial equipment and convert them into usable electricity, reducing the overall energy consumption of the manufacturing process. The second part of the thesis explores modular component build, which enables easy replacement, upgrading, and servicing of components, thus reducing waste and prolonging product lifespan. This approach contributes to sustainable manufacturing and complements the energy harvesting aspect by minimising emissions. The third part of the thesis examines upcycling, which involves repurposing waste materials into new products or components. This concept supports the circular economy and synergises with the energy harvesting and modular component build strategies to further reduce waste and emissions in manufacturing. The results reveal that upcycling can substantially enhance manufacturing sustainability. Overall, this thesis emphasises the importance of integrating energy harvesting, modular component build, and upcycling strategies in manufacturing to achieve net-zero emissions. The findings contribute to the growing body of knowledge on sustainable manufacturing practices, offering valuable insights for manufacturers, policymakers, and researchers in the pursuit of net-zero emissions.

description: When a strong laser pulse induces the ionization of an atom, momentum conservation dictates that the absorbed photons transfer their momentum $p_γ=E_γ/c$ to the electron and its parent ion. Even after 30 years of studying strong-field ionization, the sharing of the photon momentum between the two particles and its underlying mechanism are still under debate in theory. Corresponding experiments are very challenging due to the extremely small photon momentum ($~10^{-4}$ a.u.) and their precision has been too limited, so far, to ultimately resolve the debate. Here, by utilizing a novel experimental approach of two counter-propagating laser pulses, we present a detailed study on the effects of the photon momentum in strong-field ionization. The high precision and self-referencing of the method allows to unambiguously demonstrate the action of the light's magnetic field on the electron while it is under the tunnel barrier, confirming theoretical predictions, disproving others. Our results deepen the understanding of, for example, molecular imaging and time-resolved photoelectron holography.

description: We study the evolution of dynamic fluctuations averaged over different space lengths and time scales to characterize spatially and temporally heterogeneous behavior of TIP4P/2005 water in liquid and supercooled states. Analysing a million particle simulated system we provide evidence of the existence, upon supercooling, of a significant enhancement of spatially localized dynamic fluctuations stemming from regions of correlated mobile molecules. We show that both the magnitude of the departure from the value expected for the system-size dependence of an uncorrelated system and the molecular size at which such trivial regime is finally recovered clearly increase upon supercooling. This provides a means to estimate an upper limit to the maximum length scale of influence of the regions of correlated mobile molecules. Notably, such upper limit grows two orders of magnitude on cooling, reaching a value corresponding to a few thousand molecules at the lowest investigated temperature.

description: The stability of a Bose-Einstein condensed state of trapped ultra-cold atoms is investigated under the assumption of an attractive two-body and a repulsive three-body interaction. The Ginzburg-Pitaevskii-Gross (GPG) nonlinear Schrödinger equation is extended to include an effective potential dependent on the square of the density and solved numerically for the $s-$wave. The lowest frequency of the collective mode is determined through the Fourier transform of the time dependent solution and its dependences on the number of atoms and the strength of the three-body force are studied. We show that the addition of three-body dynamics can allow the number of condensed atoms to increase considerably, even when the strength of the three-body force is very small compared with the strength of the two-body force.

description: Ghost imaging is a quantum optics technique that uses correlations between two beams to reconstruct an image in one beam from photons that do not interact with the object being imaged. While pairwise (second order) correlations are usually used to create the image, higher order correlations can be utilized to improve the performance of ghost imaging. In this paper, we demonstrate higher order atomic ghost imaging, using entangled ultracold metastable helium atoms from an s-wave collision halo. We construct higher order ghost images up to 5th order and show that using higher order correlations can improve the visibility of the images without impacting the resolution. This is the first demonstration of higher order ghost imaging with massive particles and the first higher order ghost imaging protocol of any type using a quantum source.

description: Life is stressful, and so the ability to respond appropriately to physiological stress is an essential skill for all living organisms. This thesis examines the mechanisms the brain uses to control mitochondrial health in the rest of the body. The results presented in this thesis describe two novel molecular pathways which originate in the nervous system and impact intestinal mitochondrial health. These results may have interesting implications for disease states where neuronal communication is disrupted – for example, during neurodegenerative diseases – which have metabolic impacts on various body systems.

Year: 2025

In this webinar the E-STATCOM (Enhanced Static Synchronous Compensator) is introduced as a cutting-edge solution leveraging grid-forming (GFM) technology. We will explore its technology overview, control structure, and methods to measure its grid-forming capabilities. Rather than merely stating whether a device is GFM, we will quantify its benefits through metrics such as inertia and short circuit power. The webinar will also present comparative plots illustrating the performance differences between GFM and grid-following systems. By the end, participants will gain a comprehensive understanding of how E-STATCOM can significantly improve grid resilience and reliability, making it a pivotal component in modern power systems.

description: We study the dynamical stability against bar-mode deformation of rapidly and differentially rotating stars in the first post-Newtonian approximation of general relativity. We vary the compaction of the star $M/R$ (where $M$ is the gravitational mass and $R$ the equatorial circumferential radius) between 0.01 and 0.05 to isolate the influence of relativistic gravitation on the instability. For compactions in this moderate range, the critical value of $β\equiv T/W$ for the onset of the dynamical instability (where $T$ is the rotational kinetic energy and $W$ the gravitational binding energy) slightly decreases from $\sim 0.26$ to $\sim 0.25$ with increasing compaction for our choice of the differential rotational law. Combined with our earlier findings based on simulations in full general relativity for stars with higher compaction, we conclude that relativistic gravitation {\em enhances} the dynamical bar-mode instability, i.e. the onset of instability sets in for smaller values of $β$ in relativistic gravity than in Newtonian gravity. We also find that once a triaxial structure forms after the bar-mode perturbation saturates in dynamically unstable stars, the triaxial shape is maintained, at least for several rotational periods. To check the reliability of our numerical integrations, we verify that the general relativistic Kelvin-Helmholtz circulation is well-conserved, in addition to rest-mass energy, total mass-energy, linear and angular momentum. Conservation of circulation indicates that our code is not seriously affected by numerical viscosity. We determine the amplitude and frequency of the quasi-periodic gravitational waves emitted during the bar formation process using the quadrupole formula.

description: It is intuitive that semantic representations can be useful for machine translation, mainly because they can help in enforcing meaning preservation and handling data sparsity (many sentences correspond to one meaning) of machine translation models. On the other hand, little work has been done on leveraging semantics for neural machine translation (NMT). In this work, we study the usefulness of AMR (short for abstract meaning representation) on NMT. Experiments on a standard English-to-German dataset show that incorporating AMR as additional knowledge can significantly improve a strong attention-based sequence-to-sequence neural translation model.

description: This study reports the superior tensile properties of laser powder bed fused (L-PBF) Hastelloy X compared to wrought, exhibiting enhanced yield strength and improved ductility. By analyzing the tensile response of a variety of microstructures ranging from fully dendritic to fully solutionized, the as-solidified fine inter-dendritic region network was determined to be responsible for this superiority. Characterized by high chemical gradients, the inter-dendritic regions limited motion of dislocations, blocked the formation of long deformation bands, and promoted the uniform distribution of plastic strain. Further, a deformation mechanism not well known for Hastelloy X, i.e. deformation twinning, was observed and analyzed. Superior tensile properties of as-fabricated, additively manufactured Hastelloy X relative to the wrought counterpart is reported. Room temperature deformation twinning is also observed in both as-fabricated and heat-treated conditions.

description: We analyze the differences in infrared circumstellar dust emission between oxygen rich Mira and non-Mira stars, and find that they are statistically significant. In particular, we find that these stars segregate in the K-[12] vs. [12]-[25] color-color diagram, and have distinct properties of the IRAS LRS spectra, including the peak position of the silicate emission feature. We show that the infrared emission from the majority of non-Mira stars cannot be explained within the context of standard steady-state outflow models. The models can be altered to fit the data for non-Mira stars by postulating non-standard optical properties for silicate grains, or by assuming that the dust temperature at the inner envelope radius is significantly lower (300-400 K) than typical silicate grain condensation temperatures (800-1000 K). We argue that the latter is more probable and provide detailed model fits to the IRAS LRS spectra for 342 stars. These fits imply that 2/3 of non-Mira stars and 1/3 of Mira stars do not have hot dust ($>$ 500 K) in their envelopes. The absence of hot dust can be interpreted as a recent (order of 100 yr) decrease in the mass-loss rate. The distribution of best-fit model parameters agrees with this interpretation and strongly suggests that the mass loss resumes on similar time scales. Such a possibility appears to be supported by a number of spatially resolved observations (e.g. recent HST images of the multiple shells in the Egg Nebula) and is consistent with new dynamical models for mass loss on the Asymptotic Giant Branch.

description: Overactive bladder syndrome (OAB) is a clinical syndrome with or without urgency incontinence, usually associated with frequent urination and nocturnal urination. To date, it has been established that detrusor hyperactivity is the cause of frequent and urgent urination in most patients. The problem of diagnosis and successful treatment of patients with OAB is a problem that requires the involvement of doctors of various specialties, primarily urologists, neurologists and neurosurgeons. In many cases, attention is paid to the fact that it is impossible to determine the real cause of the development of OAB, which requires the continuation of research aimed at determining the etiological factors of OAB [Mazo E. B., Krivoborodov G. G. Hyperactive urinary bladder //Consilium medicum. - 2003. - T. 5. – no. 7. - S. 405-411].

description: In this study, reduction-sensitive self-assembled polymer nanoparticles based on poly (lactic-co-glycolic acid) (PLGA) and chondroitin sulfate A (CSA) were developed and characterized. PLGA was conjugated with CSA via a disulfide linkage (PLGA-ss-CSA). The critical micelle concentration (CMC) of PLGA-ss-CSA conjugate is 3.5 µg/mL. The anticancer drug doxorubicin (DOX) was chosen as a model drug, and was effectively encapsulated into the nanoparticles (PLGA-ss-CSA/DOX) with high loading efficiency of 15.1%. The cumulative release of DOX from reduction-sensitive nanoparticles was only 34.8% over 96 h in phosphate buffered saline (PBS, pH 7.4). However, in the presence of 20 mM glutathione-containing PBS environment, DOX release was notably accelerated and almost complete from the reduction-sensitive nanoparticles up to 96 h. Moreover, efficient intracellular DOX release of PLGA-ss-CSA/DOX nanoparticles was confirmed by CLSM assay in A549 cells. In vitro cytotoxicity study showed that the half inhibitory concentrations of PLGA-ss-CSA/DOX nanoparticles and free DOX against A549 cells were 1.141 and 1.825 µg/mL, respectively. Therefore, PLGA-ss-CSA/DOX nanoparticles enhanced the cytotoxicity of DOX in vitro. These results suggested that PLGA-ss-CSA nanoparticles could be a promising carrier for drug delivery.

description: Simple approach is used to a description of the experimental data for the widths of fission fragment mass yields in 197Au and 209Bi at low and intermediate energies. This approach based on both the expression for the temperature dependence of the width of fission fragment mass yield and the mass of the most probable fragment. The expression for the width of fission fragment mass yield depends on the mass of the most probable fragment, the surface terms of the energy level density parameter, the temperature and the stiffness parameter of the potential related to mass-asymmetric degree of freedom. It is shown that the contribution of the surface term of the energy level density parameter into the width is important for description of the experimental data in wide range of energies.

description: The nonadiabatic electron-phonon corrections for the superconducting pairing are investigated for a specific tight-binding model corresponding to a 2d square lattice. This permits to investigate the role of various specific properties like the band filling, nesting effects and a realistic van Hove singularity on the superconducting effective pairing beyond Migdal's limit. The main results are: (i) Starting from a momentum independent electron-phonon coupling the nonadiabatic effects lead to an effective pairing which is strongly dependent on frequency and momentum. (ii) If instead the electron-phonon coupling is mainly forward (as due to correlation effects) the resulting pairing results to be strongly enhanced. These results confirm but also extend the simplified scheme used up to now to compute these properties. In this respect our results link the nonadiabatic effects to the specific properties of realistic materials.

description: In den letzten Jahren wurden nach der Ankunft einer großen Zahl von Geflüchteten häufig Ehrenamtliche eingesetzt, um erste Deutschkenntnisse zu vermitteln. Um die Ehrenamtlichen auf diese Aufgabe vorzubereiten, wurden von verschiedenen Institutionen Konzepte zur Qualifizierung von Ehrenamtlichen entwickelt. Da die Institutionen, die die Konzepte entwickelten, nicht auf Forschungsergebnisse oder Erfahrungen aus der Vergangenheit zurückgreifen konnten, orientierten sie sich häufig an Konzepten für Lehrkräfte. Um zukünftig passgenauere Konzepte entwickeln zu können, wurden im Rahmen dieser Studie Ehrenamtliche befragt, die bereits über einen längeren Zeitraum im Bereich der Sprachvermittlung tätig waren. Ziel dieser Arbeit war es, herauszufinden, wie Konzepte für Ehrenamtliche in der Sprachvermittlung entwickelt werden müssen, um den Besonderheiten der Zielgruppe gerecht zu werden. Dazu wurde untersucht, welche Rollen Ehrenamtliche während ihres Engagements einnehmen. Darüber hinaus wurde überprüft, welche Aufgaben sie im Rahmen ihres Engagements übernehmen und wie sie die Tätigkeit erleben. Für die Datenerhebung wurden Tagebücher genutzt, die die Ehrenamtlichen nach den Treffen mit den Grundschüler*innen ausfüllten. Weiterhin wurden Daten mittels Repertory Grid-Interviews erhoben. Die Daten wurden mithilfe der strukturierenden qualitativen Inhaltsanalyse ausgewertet. Dabei wurde deutlich, dass vor allem curriculare Vorgaben und die Zusammenarbeit zwischen Ehrenamtlichen und Hauptamtlichen bemängelt wurden. Aus den Aussagen der Ehrenamtlichen wurden erste Leitgedanken abgeleitet, die bei der Entwicklung zukünftiger Konzepte helfen können, die Ehrenamtlichen besser auf ihren Einsatz vorzubereiten und sie in ihrer Arbeit effektiver zu unterstützen.

description: A versatile new approach for calculating the depletion potential in a hard sphere mixture is presented. This is valid for any number of components and for arbitrary densities. We describe two different routes to the depletion potential for the limit in which the density of one component goes to zero. Both routes can be implemented within density functional theory and simulation. We illustrate the approach by calculating the depletion potential for a big hard sphere in a fluid of small spheres near a planar hard wall. The density functional results are in excellent agreement with simulations.

description: The generation of optical pulses at ultra low bias level, thus low energy cost, is explored in a commercial microcavity semiconductor laser in view of testing the principle of energy efficient information encoding in potential integrated schemes. Sequences of regular, highly nonlinear pulses with acceptable amplitude stability are obtained from a commercial device as potential sources of bits where the information is added by post-treatment (pulse removal). A discussion on the energy expenditure per bit is offered, together with the optimal frequency for pulse generation, which is found to lie slightly below the above-threshold value declared by the manufacturer.

description: In recent papers we have proposed that the dark matter of the Universe could be from scalar field origin. In this letter, we find that if the scale of renormalization of the model is of order of the Planck Mass, then a scalar field $Φ$ endowed with the scalar potential $V=V_{o}[\cosh {(λ\sqrt{κ_{0}}Φ)}-1] can be a reliable model for dark matter in galaxies. The predicted scattering cross section fits the value required for self-interacting dark matter and the additional degree of freedom of the theory is of order of hundreds of TeV.

Various configurations of the support frame and coupling to the pulse tube compressor and motor have been tested, and the dominant contribution in the spectrum of vibrations is located, surprisingly, near 20 kHz. Finally, the efficiency of various precautions in suppressing the observed vibration levels is illustrated.

description: We examine the orientations of rich galaxy cluster X-ray isophotes with respect to their rich nearest neighbors using existing samples of Abell cluster position angles measured from {\it Einstein} and {\it ROSAT} observations. We study a merged subset of these samples using updated and improved positions and redshifts for Abell/ACO clusters. We find high confidence for alignment, which increases as nearest neighbor distance is restricted. We conclude that there is a strong alignment signal in all this data, consistent with gravitational instability acting on Gaussian perturbations.

Hierarchical 2-D Feature Coding for Secure Pilot Authentication in Multi-User Multi-Antenna OFDM Systems: A Reliability Bound Contraction Perspective

description: Due to the publicly known and deterministic characteristic of pilot tones, pilot authentication (PA) in multi-user multi-antenna orthogonal frequency-division multiplexing systems is very susceptible to the jamming/nulling/spoofing behaviors. To solve this, in this paper, we develop a hierarchical 2-D feature (H2DF) coding theory that exploits the hidden pilot signal features, i.e., the energy feature and independence feature, to secure pilot information coding which is applied between legitimate parties through a well-designed five-layer hierarchical coding model to achieve secure multiuser PA (SMPA). The reliability of SMPA is characterized using the identification error probability (IEP) of pilot encoding and decoding with the exact closed-form upper and lower bounds. However, this phenomenon of non-tight bounds brings about the risk of long-term instability in SMPA. Therefore, a reliability bound contraction theory is developed to shrink the bound interval, and practically, this is done by an easy-to-implement technique, namely, codebook partition within the H2DF code. In this process, a tradeoff between the upper and lower bounds of IEP is identified and a problem of optimal upper and lower bound tradeoff is formulated, with the objective of optimizing the cardinality of sub-codebooks such that the upper and lower bounds coincide. Solving this, we finally derive an exact closed-form expression for IEP, which realizes a stable and highly reliable SMPA. Numerical results validate the stability and resilience of H2DF coding in SMPA.
An Infrared Camera for Leuschner Observatory and the Berkeley Undergraduate Astronomy Lab

description: We describe the design, fabrication, and operation of an infrared camera which is in use at the 30-inch telescope of the Leuschner Observatory. The camera is based on a Rockwell PICNIC 256 x 256 pixel HgCdTe array, which is sensitive from 0.9-2.5 micron. The primary purpose of this telescope is for undergraduate instruction. The cost of the camera has been minimized by using commercial parts whereever practical. The camera optics are based on a modified Offner relay which forms a cold pupil where stray thermal radiation from the telescope is baffled. A cold, six-position filter wheel is driven by a cryogenic stepper motor, thus avoiding any mechanical feed throughs. The array control and readout electronics are based on standard PC cards; the only custom component is a simple interface card which buffers the clocks and amplifies the analog signals from the array.

description: Superconducting ratio-frequency (SRF) cavities, cooled by superfluid helium-4 (He II), are key components in modern particle accelerators. Quenches in SRF cavities caused by Joule heating from local surface defects can severely limit the maximum achievable accelerating field. Existing methods for quench spot detection include temperature mapping and second-sound triangulation. These methods are useful but all have known limitations. Here we describe a new method for surface quench spot detection by visualizing the heat transfer in He II via tracking He$_2^*$ molecular tracer lines. A proof-of-concept experiment has been conducted, in which a miniature heater mounted on a plate was pulsed on to simulate a surface quench spot. A He$_2^*$ tracer line created nearby the heater deforms due to the counterflow heat transfer in He II. By analyzing the tracer-line deformation, we can well reproduce the heater location within a few hundred microns, which clearly demonstrates the feasibility of this new technology. Our analysis also reveals that the heat content transported in He II is only a small fraction of the total input heat energy. We show that the remaining energy is essentially consumed in the formation of a cavitation zone near the heater. By estimating the size of this cavitation zone, we discuss how the existence of the cavitation zone may explain a decades-long puzzle observed in many second-sound triangulation experiments.

A multifiltering study of turbulence in a large sample of simulated galaxy clusters

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We present results from a large set of N-body/SPH hydrodynamical cluster simulations aimed at studying the statistical properties of turbulence in the ICM. The numerical hydrodynamical scheme employs a SPH formulation in which gradient errors are strongly reduced by using an integral approach. We consider both adiabatic and radiative simulations. We construct clusters subsamples according to the cluster dynamical status or gas physical modeling, from which we extract small-scale turbulent velocities obtained by applying to cluster velocities different multiscale filtering methods. The velocity power spectra of non-radiative relaxed clusters are mostly solenoidal and steeper than Kolgomorov. Cooling runs are distinguished by much shallower spectra, a feature which we interpret as the injection of turbulence at small scales due to the interaction of compact cool gas cores with the ICM. Turbulence in galaxy clusters is then characterized by multiple injection scales, with the small scale driving source acting in addition to the large scale injection mechanisms. Cooling runs of relaxed clusters exhibit enstrophy profiles with a power-law behavior over more than two decades in radius, and a turbulent-to-thermal energy ratio ~1 %. In accord with Hitomi observations, in the core of a highly relaxed cluster we find low level of gas motions. In addition, the estimated cluster radial profile of the sloshing oscillation period exhibits an associated Froude number satisfying Fr ~ 0.1 within r / r_{200}
