description: A classical hydrodynamic approach is used to calculate the magnetoplasma excitations of two vertically coupled electron dots. The electrons are confined by different parabolic potentials in which case Kohn's theorem is no longer valid. The equilibrium density profiles of the electrons in both dots are calculated as function of the interdot distance. We find that for unequal confinements of the two dots the electron density in one of the dots becomes ring-like. The electron densities are then used to obtain the magnetoplasma frequencies. The oscillator strengths are calculated, and we find that other then the center of mass modes can be excited due to the electron-electron interactions.

First and second order transition of frustrated Heisenberg spin systems

description: Starting from the hypothesis of a second order transition we have studied modifications of the original Heisenberg antiferromagnet on a stacked triangular lattice (STA-model) by the Monte Carlo technique. The change is a local constraint restricting the spins at the corners of selected triangles to add up to zero without stopping them from moving freely (STAR-model). We have studied also the closely related dihedral and trihedral models which can be classified as Stiefel models. We have found indications of a first order transition for all three modified models instead of a universal critical behavior. This is in accordance with the renormalization group investigations but disagrees with the Monte Carlo simulations of the original STA-model favoring a new universality class. For the corresponding x-y antiferromagnet studied before, the second order nature of the transition could also not be confirmed.

description: Because core-collapse supernovae are the explosions of massive stars, which have relatively short lifetimes, they occur almost exclusively in galaxies with active star formation. On the other hand, the Type Ibn supernova PS1-12sk exploded in an environment much more typical of thermonuclear (Type Ia) supernovae: on the outskirts of the brightest elliptical galaxy in a galaxy cluster. The lack of any obvious star formation at that location presented a challenge to models of Type Ibn supernovae as the explosions of very massive Wolf-Rayet stars. Here we present a supplementary search for star formation at the site of PS1-12sk, now that the supernova has faded, via deep ultraviolet imaging of the host cluster with the Hubble Space Telescope. We do not detect any ultraviolet emission within 1 kpc of the supernova location, which allows us deepen the limit on star formation rate by an order of magnitude compared to the original study on this event. In light of this new limit, we discuss whether the progenitors of Type Ibn supernovae can be massive stars and what reasonable alternatives have been proposed.

Roughening Transition of a Restricted Solid-on-Solid Model in the Directed Percolation Universality Class

description: We carried out a finite-size scaling analysis of the restricted solid-on-solid version of a recently introduced growth model that exhibits a roughening transition accompanied by spontaneous symmetry breaking. The dynamic critical exponent of the model was calculated and found to be consistent with the universality class of the directed percolation process in a symmetry-broken phase with a crossover to Kardar-Parisi-Zhang behavior in a rough phase. The order parameter of the roughening transition together with the string order parameter was calculated, and we found that the flat, gapped phase is disordered with an antiferromagnetic spin-fluid structure of kinks, although strongly dominated by the completely flat configuration without kinks. A possible interesting extension of the model is mentioned.

description: In the modern era, people demand that type of  food which contain minimum changes in sensor and nutritional level, this led to the development of hurdle technology in the field of food technology .Hurdle technology is a new concept in the preservation of foods of plant as well as animal origin. The factors used for food preservation are known as hurdles. Hurdles is applied to inhibit or eliminate the growth of microbes, which can either cause spoilage. It is imperative to use at least two or three hurdles in the system to control organisms. Each hurdle puts the microorganisms in a hostile environment so that no multiplication can occur in the food, and thereby, extend the shelf life of the food products. Hurdle technology is also known as combine method technology.

Insights into FtsZ inhibitors and their use against antibiotic-resistant bacterial pathogens
Creators: name: Ferrer-González, Edgar F.
Publisher: name: No Publisher Supplied
Year: 2021

description: Antibiotic resistance is one of the biggest public health challenges of our time. The emergence and spread of drug-resistant pathogens threatens our ability to treat common infections. This problem is exacerbated by the dwindling pipeline of new antimicrobial agents. This dissertation explores the mechanism by which FtsZ inhibitors overcome the resistance properties of methicillin-resistant Staphylococcus aureus (MRSA). MRSA resistance to β-lactam antibiotics is predominantly driven by the acquisition of a fifth penicillin binding protein (PBP), termed PBP2a. β-lactam antibiotics have a low binding affinity for PBP2a, allowing MRSA to survive in the presence of these drugs. When β-lactam antibiotics are used in combination with a FtsZ inhibitor they become active against MRSA. To probe the mechanism underlying this behavior, we first determined the relative binding affinities of various β-lactam antibiotics for S. aureus PBP1, PBP2, PBP3, and PBP4. Using this information, we explored the relationship between PBP targeting selectivity and the extent of antibacterial synergy observed when combining different β-lactam antibiotics with a FtsZ inhibitor. Our findings indicate that β-lactam antibiotics with a high binding affinity for PBP2 exhibit the greatest extent of synergistic activity with FtsZ inhibitors. To further understand the nature of this synergistic relationship, we analyzed the impact of FtsZ inhibition on the relative localization of FtsZ and the five PBPs present in MRSA using fluorescence microscopy. Our results suggest that PBP2 plays a major role in the cell wall remodeling and repair necessitated by FtsZ inhibition and that PBP2a does not complement this function. Without a complementary contribution from PBP2a, PBP2 becomes highly vulnerable to PBP2-selective β-lactam antibiotics, thereby underscoring the high degree of synergistic activity between these drugs and FtsZ inhibitors. In addition to these findings, the development and validation of a fluorescent FtsZ inhibitor (BOFP) is also presented. Our results show that BOFP can be utilized to visualize and study FtsZ in a broad range of both Gram-negative and Gram-positive bacterial pathogens of acute clinical importance. This powerful tool will enable us to identify new broad-spectrum FtsZ inhibitors and understand their mechanisms of action, while expedite the knowledge on FtsZ.

description: The ground state of the Holstein molecular crystal model in one dimension is studied using the Global-Local variational method, analyzing in particular the total energy, kinetic energy, phonon energy, and interaction energy over a broad region of the polaron parameter space. Through the application of objective criteria, a unique curve is identified that simply, accurately, and robustly locates the self-trapping transition separating small polaron and large polaron behavior.

description: The lattice fluid model of the system with short range and long range Coulomb interactions is suggested. In the framework of the collective variables method, the screening of the Coulomb interactions in the bulk is considered. It is shown that the Debye length includes additional concentration dependence inversely proportional to the square root of the mean concentration of vacant sites like what is known at the plane boundary. The Coulomb interaction contribution to the free energy of the system is calculated in the approach close to the mean spherical approximation and is given in an analytical form. The influence of the variation of the crystal field near the system boundary on the structure and characteristics of the electric double layer is investigated. As compared to the system with equal crystal potentials at the lattice sites throughout the system the pronounced difference for the electric capacitance appears at low absolute values of the surface potential and it is more pronounced for negative electric potentials. The capacitance diverges as the potential values at which the electric field tends to zero and attains negative values in regions of the surface potentials depending on their polarity and values of the surface crystal potential. Negative values of the capacitance may indicate the thermodynamic instability of the system that can result from neglecting the short range interaction contribution.

description: We introduce the generalized equidistant Chebyshev polynomials T(k,h) of kind k of hyperkind h, where k,h are positive integers. They are obtained by a generalization of standard and monic Chebyshev polynomials of the first and second kinds. This generalization is fulfilled in two directions. The horizontal generalization is made by introducing hyperkind h and expanding it to infinity. The vertical generalization proposes expanding kind k to infinity with the help of the method of equidistant coefficients. Some connections of these polynomials with the Alexander knot and link polynomial invariants are investigated.

The molecules were pumped with linear polarized laser pulses creating an excited state population with a preferred orientational (alignment) direction. Two time scales of $1.9\pm1.5$ ps and $46\pm10$ ps were revealed by model-independent XCCA, associated with an internal structural changes and rotational dephasing, respectively. Our studies illustrate the potential of XCCA to reveal hidden structural information in a model independent analysis of time evolution of solvated metal complex molecules.

description: When a large blunt object penetrates into a granular material, the force response exhibits an initial nonlinear relationship with depth that is widely attributed to the formation of a shear jammed stagnant zone. We present an experimental study of a model 2D granular system that preserves common aspects of slow granular penetration, such as a linear force law for large depths, while also allowing for direct and precise measurement of a stagnant zone. We also probe structural anisotropies throughout the bed and examine their characteristics inside and outside the stagnant zone. Finally, we simultaneously consider effects of concave elongated particle shapes (dimers) and find that while most results are not affected, the relationship between local structure and strain suggests a distinct fragility in the stagnant zone.

An analysis the positional accuracy of a multi-camera ball tracking system
Creators: name: Zhu, Jiale
Publisher: name: No Publisher Supplied
Year: 2021

description: This paper describes three kinds of pinhole camera models: the camera without lens distortion and calibration, the camera with lens distortion, and the distorted camera calibrated using an inverse lens distortion series of different orders. In this paper, most equations are in matrix form, which makes programming dramatically more comfortable. During the lens distortion process, we used second-order coefficients to simulate the lens distortion. Due to the quantization error when converting image coordinates to pixel coordinates, the actual distortion coefficients are estimated by a least-squares algorithm. The estimated distortion coefficients are applied in the inverse lens distortion series to calibrate the cameras. The position of the ball is triangulated by using a system of eight cameras. The triangulation algorithm will be introduced in Chapter 4. Finally, Chapter 5 compares the performance of the system with and without lens distortion and with various levels of camera calibration to correct for lens distortion.

Process parameter optimisation and thermal characterisation of coaxial multi-laser metal wire additive manufacturing with 316L stainless steel
Creators: name: Roberts, Matthew
Publisher: name: Lancaster University
Year: 2024

description: Laser Metal Wire Additive Manufacturing systems (LWAM), with coaxially
 mounted lasers, are emerging onto the additive manufacturing market. They
 use relatively fine wire feedstock and have high efficiency in terms of
 energy and deposition speeds compared to other metal wire technologies,
 making a credible technology to fill the gap between slower, precise metal
 powder technologies and faster, lower-fidelity wire-arc technologies.
 Limited research is available for this technology. Commercial slicing
 software, based on more forgiving polymers, is also limited in its ability
 to accommodate more complex dynamics of metal wire additive manufacturing.

 This thesis uses the Meltio M450 to investigate the relationship between
 laser power, extrusion rate and head speed and the resulting track
 geometry and layer quality. The research identifies the process parameters
 required to produce high-quality tracks repeatedly. New insights are
 developed into the use of machine learning to predict quality and geometry
 of beads, showing how these tools reduce the need for experimental trials.
 Using Machine Learning to address uncertainty in the prediction of track
 widths adds new insights to the application of machine learning in the
 field of metal additive manufacturing.

 A single-layer model is developed to predict layer height, adding to the
 existing body of work by quantifying the effect of the number of tracks
 and track separation on the resulting layer height. Experiments to measure
 interlayer temperature and bulk heating during the deposition process are
 used with modelling to show a new method for using the base substrate
 temperature to infer interlayer temperatures when interlayer pauses of
 sixty seconds or longer are used.

 This thesis has developed novel methods for process optimisation, geometry
 prediction and interlayer temperature control, which address some of the
 key research gaps for coaxial LWAM and add to the body of knowledge in
 this area to support improved slicing tools.

description: Indoor location identification and navigation need to be as simple, seamless, and ubiquitous as its outdoor GPS-based counterpart is. It would be of great convenience to the mobile user to be able to continue navigating seamlessly as he or she moves from a GPS-clear outdoor environment into an indoor environment or a GPS-obstructed outdoor environment such as a tunnel or forest. Existing infrastructure-based indoor localization systems lack such capability, on top of potentially facing several critical technical challenges such as increased cost of installation, centralization, lack of reliability, poor localization accuracy, poor adaptation to the dynamics of the surrounding environment, latency, system-level and computational complexities, repetitive labor-intensive parameter tuning, and user privacy. To this end, this paper presents a novel mechanism with the potential to overcome most (if not all) of the abovementioned challenges. The proposed mechanism is simple, distributed, adaptive, collaborative, and cost-effective. Based on the proposed algorithm, a mobile blind device can potentially utilize, as GPS-like reference nodes, either in-range location-aware compatible mobile devices or preinstalled low-cost infrastructure-less location-aware beacon nodes. The proposed approach is model-based and calibration-free that uses the received signal strength to periodically and collaboratively measure and update the radio frequency characteristics of the operating environment to estimate the distances to the reference nodes. Trilateration is then used by the blind device to identify its own location, similar to that used in the GPS-based system. Simulation and empirical testing ascertained that the proposed approach can potentially be the core of future indoor and GPS-obstructed environments.

On the stability of 2 \sqrt{2} x 2 \sqrt{2} oxygen ordered superstructures in YBa2Cu3O6+x

description: We have compared the ground-state energy of several observed or proposed " 2 \sqrt{2} x 2 \sqrt{2} oxygen (O) ordered superstructures " (from now on HS), with those of "chain superstructures" (CS) (in which the O atoms of the basal plane are ordered in chains), for different compositions x in YBa2Cu3O6+x. The model Hamiltonian contains i) the Madelung energy, ii) a term linear in the difference between Cu and O hole occupancies which controls charge transfer, and iii) covalency effects based on known results for $t-J$ models in one and two dimensions. The optimum distribution of charge is determined minimizing the total energy, and depends on two parameters which are determined from known results for x=1 and x=0.5. We obtain that on the O lean side, only CS are stable, while for x=7/8, a HS with regularly spaced O vacancies added to the x=1 structure is more stable than the corresponding CS for the same x. We find that the detailed positions of the atoms in the structure, and long-range Coulomb interactions, are crucial for the electronic structure, the mechanism of charge transfer, the stability of the different phases, and the possibility of phase separation.

description: Surface erosion and secondary electron emission (SEE) have been identified as the most critical life-limiting factors in channel walls of Hall-effect thrusters for space propulsion. Recent wall concepts based on micro-architected surfaces have been proposed to mitigate surface erosion and SEE. The idea behind these designs is to take advantage of very-high surface-to-volume ratios to reduce SEE and ion erosion by internal trapping and redeposition. This has resulted in renewed interest to study electron-electron processes in relevant thruster wall materials. In this work, we present calculations of SEE yields in micro-porous hexagonal BN surfaces using stochastic simulations of electron-material interactions in discretized surface geometries. Our model consists of two complementary parts. First we study SEE as a function of primary electron energy and incidence angle in flat surfaces using Monte Carlo simulations of electron multi-scattering processes. The results are then used to represent the response function of discrete surface elements to individual electron rays generated using a ray-tracing Monte Carlo model. We find that micro-porous surfaces result in SEE yield reductions of over 50% in the energy range experienced in Hall thrusters. This points to the suitability of these micro-architected surface concepts to mitigate SEE-related issues in compact electric propulsion devices.
Multifractality of entangled random walks and non-uniform hyperbolic spaces

description: Multifractal properties of the distribution of topological invariants for a model of trajectories randomly entangled with a nonsymmetric lattice of obstacles are investigated. Using the equivalence of the model to random walks on a locally nonsymmetric tree, statistical properties of topological invariants, such as drift and return probabilities, have been studied by means of a renormalization group (RG) technique. The comparison of the analytical RG--results with numerical simulations as well as with the rigorous results of P.Gerl and W.Woess demonstrates clearly the validity of our approach. It is shown explicitly by direct counting for the discrete version of the model and by conformal methods for the continuous version that multifractality occurs when local uniformity of the phase space (which has an exponentially large number of states) has been broken.

description: We calculate the magnetic field and temperature dependence of the Raman response, superfluid density and the NMR relaxation rate in the vortex state of a d-wave superconductor arising from the Doppler energy shift of extended quasiparticle states. Our results are valid both at low temperatures, where we observe scaling with variable $TH^{-1/2}$ and obtain explicit form of the scaling functions, and beyond this region. We derive a universal frequency dependent scaling relation for the Raman response, and discuss the breakdown of the single relaxation rate approach to NMR response.

description: Accurate rainfall forecasting is crucial for mitigating the impacts of extreme weather conditions,especially in cities like Chennai, which are prone to floods and waterlogging due to heavy monsoon rains.Machine learning techniques, particularly ensemble learning models like LightGBM (Light GradientBoosting Machine) and XGBoost (Extreme Gradient Boosting), have demonstrated significant potentialin improving rainfall prediction accuracy. A comparative analysis of LightGBM and XGBoost evaluatestheir performance in forecasting rainfall patterns in Chennai. Historical weather data, includingtemperature, humidity, pressure, and past rainfall records, serve as inputs for training and testing bothmodels to assess their effectiveness. Results indicate that while both models enhance predictive capabilitiescompared to traditional statistical approaches, one outperforms the other in terms of accuracy, computationalefficiency, and interpretability. The findings contribute to improving rainfall forecasting for better disasterpreparedness and water resource management in Chennai.

description: In the usual entanglement detection scenario the possible measurements and the corresponding data are assumed to be fully characterized. We consider the situation where the measurements are known, but the data is scrambled, meaning the assignment of the probabilities to the measurement outcomes is unknown. We investigate in detail the two-qubit scenario with local measurements in two mutually unbiased bases. First, we discuss the use of entropies to detect entanglement from scrambled data, showing that Tsallis- and Rényi entropies can detect entanglement in our scenario, while the Shannon entropy cannot. Then, we introduce and discuss scrambling-invariant families of entanglement witnesses. Finally, we show that the set of non-detectable states in our scenario is non-convex and therefore in general hard to characterize.

NOTE
 The presence of Sloanea usurpatrix Sprague & Riley in French Guiana seems plausible given its known trans-Amazonian distribution. According to Pennington & Wise (2017), it is attested by a single sterile collection (Nouragues Nature Reserve, 40 km SW of Regina, Mori et al. 26678, CAY, K). However, the leaf morphology of this specimen clearly differs from that of S. usurpatrix, while fitting perfectly with S. synandra.
