description: Quantum optimal control is a technique for controlling the evolution of a quantum system and has been applied to a wide range of problems in quantum physics. We study a binary quantum control optimization problem, where control decisions are binary-valued and the problem is solved in diverse quantum algorithms. In this paper, we utilize classical optimization and computing techniques to develop an algorithmic framework that sequentially optimizes the number of control switches and the duration of each control interval on a continuous time horizon. Specifically, we first solve the continuous relaxation of the binary control problem based on time discretization and then use a heuristic to obtain a controller sequence with a penalty on the number of switches. Then, we formulate a switching time optimization model and apply sequential least-squares programming with accelerated time-evolution simulation to solve the model. We demonstrate that our computational framework can obtain binary controls with high-quality performance and also reduce computational time via solving a family of quantum control instances in various quantum physics applications.

description: We construct N=8 supersymmetric mechanics with four bosonic end eight fermionic physical degrees of freedom. Starting from the most general N=4 superspace action in harmonic superspace for the ({\bf 4,8,4}) supermultiplet we find conditions which make it N=8 invariant. We introduce in the action Fayet-Iliopoulos terms which give rise to potential terms. We present the action in components and give explicit expressions for the Hamiltonian and Poisson brackets. Finally we discuss the possibility of N=9 supersymmetric mechanics.

 Derived symplectic geometry studies symplectic structures on derived stacks. Derived stacks are the main players in derived geometry, the purpose of which is to deal with singular spaces, while symplectic structures are an essential ingredient of the geometric formalism of classical mechanics and classical field theory. In addition to providing an overview of a relatively young field of research, we provide a case study on Casson's invariant.

Transcriptomic analysis of rhodococcus sp. RHA1 responses to heat shock and osmotic stress
Creators: name: Ekpanyaskun, Pat
Publisher: name: University of British Columbia
Year: 2010

description: Rhodococcus sp. RMA1 is a soil actinomycete that is capable of degrading many aromatic compounds. Thus, it has potential applications in the pharmaceutical, the environmental, and the energy sectors. To efficiently exploit RHA1 in various applications, it is important to understand its responses to stress conditions commonly occurring in soil. This study focused on the global responses of exponentially growing RHA1 to heat shock and osmotic stress, primarily at the transcriptional level. Several genes that belong to the typical heat shock responses (encoding heat shock proteins), as well as the oxidative stress responses (encoding glutathione peroxidase, methionine sulfoxide reductase), were induced following heat shock. Several up-regulated genes following heat shock were related to fatty acid biosynthesis and metabolism. RHA1 adapts to osmotic stress by synthesizing the L-ectoine as a compatible solute, and possibly by turning on components of potassium transporters, KdpAB. It also induces genes encoding a tyrosine kinase and the DNA protection during starvation protein following osmotic stress. The translational machinery was repressed following both stresses; however, the repression was prolonged following the heat shock, which was lethal. Only 20 genes were found common to heat shock and osmotic stress responses. Among these are genes encoding a σ-factor similar to σF in M. tuberculosis and a transcriptional regulator similar to HspR in S. coelicolor. The induction of these two genes suggests central roles for them in stress responses, perhaps controlling other regulators that will promote or inhibit the expression of other genes, depending on the type of stress. Overall, this study provides improved understanding of adaptation mechanisms of rhodococci.
Soft Video Multicasting Using Adaptive Compressed Sensing

description: Recently, soft video multicasting has gained a lot of attention, especially in broadcast and mobile scenarios where the bit rate supported by the channel may differ across receivers, and may vary quickly over time. Unlike the conventional designs that force the source to use a single bit rate according to the receiver with the worst channel quality, soft video delivery schemes transmit the video such that the video quality at each receiver is commensurate with its specific instantaneous channel quality. In this paper, we present a soft video multicasting system using an adaptive block-based compressed sensing (BCS) method. The proposed system consists of an encoder, a transmission system, and a decoder. At the encoder side, each block in each frame of the input video is adaptively sampled with a rate that depends on the texture complexity and visual saliency of the block. The obtained BCS samples are then placed into several packets, and the packets are transmitted via a channel-aware OFDM (orthogonal frequency division multiplexing) transmission system with a number of subchannels. At the decoder side, the received BCS samples are first used to build an initial approximation of the transmitted frame. To further improve the reconstruction quality, an iterative BCS reconstruction algorithm is then proposed that uses an adaptive transform and an adaptive soft-thresholding operator, which exploits the temporal similarity between adjacent frames to achieve better reconstruction quality. The extensive objective and subjective experimental results indicate the superiority of the proposed system over the state-of-the-art soft video multicasting systems.

Based on the analytical derivations, we provide a quantitative description of the performance limits and the performance trade-off between sensing and communication in a distributed ISAC network under the given transmit power and bandwidth budget. Extensive simulations are conducted and the numerical results validate the accuracy of our derivations.
The Eight Step Change Model in Medication Error Prioritization System (MEPS) to Improve Culture of Patient Safety

Year: 2020
Subjects: subject: 111705 Environmental and Occupational Health and Safety
subject: FOS: Health sciences

description: Medication Error Prioritization System (MEPS) is used to improve the quality care and the culture of patient safety within organizations. MEPS can be effective in identifying and controlling high hazard medication (e.g., narcotics and anti-coagulants) and expired medicine and it can help with reducing preventable medical errors including errors in prescriptions, inappropriate use of medication and their adverse effects. Preventable medical errors are the leading cause of death in many countries while two-thirds of such errors could have been prevented and the most successful error-reduction strategy is MEPS. Using the online MEPS database, pharmacists answer a series of questions to report a medication error, including medication name, type of error, and location of event. Then, it provides recommendations on prevention of error and has the ability to teach employees how to prevent the error in the future. In addition, it provides insight that how the organization can improve patient safety by reviewing medication errors. For introducting MEPS and its successful implementaion, in this document I recommend the Kotter’s 8 Steps of Change Management Model which can be implemented step by step.

description: The Wiener--Hopf factorisation of a Lévy or Markov additive process describes the way that it attains new maxima and minima in terms of a pair of so-called ladder height processes. Vigon's theory of friendship for Lévy processes addresses the inverse problem: when does a process exist which has certain prescribed ladder height processes? We give a complete answer to this problem for Markov additive processes, provide simpler sufficient conditions for constructing processes using friendship, and address in part the question of the uniqueness of the Wiener--Hopf factorisation for Markov additive processes.

description: The resistivity of thin $La_{0.7}A_{0.3}MnO_{3}$ films ($A=Ca, Sr$) is investigated in a wide temperature range. The comparison of the resistivities is made among films grown by different techniques and on several substrates allowing to analyze samples with different amounts of disorder. In the low-temperature nearly half-metallic ferromagnetic state the prominent contribution to the resistivity scales as $T^α$ with $α\simeq 2.5$ for intermediate strengths of disorder supporting the theoretical proposal of single magnon scattering in presence of minority spin states localized by the disorder. For large values of disorder the low-temperature behavior of the resistivity is well described by the law $T^{3}$ characteristic of anomalous single magnon scattering processes, while in the regime of low disorder the $α$ exponent tends to a value near 2. In the high temperature insulating paramagnetic phase the resistivity shows the activated behavior characteristic of polaronic carriers. Finally in the whole range of temperatures the experimental data are found to be consistent with a phase separation scenario also in films doped with strontium ($A=Sr$).

description: The polarization plane of the cosmic microwave background radiation can be rotated either in a magnetized plasma or in the presence of a quintessential background with pseudoscalar coupling to electromagnetism. A unified treatment of these two phenomena is presented for cold and warm electron-ion plasmas at the pre-recombination epoch. The electron temperature is only relevant to the relativistic correction of the cold plasma results. The spectrum of plasma excitations is obtained from a generalized Appleton--Hartree equation, describing simultaneously the high-frequency propagation of electromagnetic waves in a magnetized plasma with a dynamical quintessence field. It is shown that these two effects are comparable for the plausible range of parameters allowed by present constraints. It is then argued that the generalized expressions derived in the present study may be relevant for direct searches of a possible rotation of the cosmic microwave background polarization.

description: This paper introduces Flamingo, a system for secure aggregation of data across a large set of clients. In secure aggregation, a server sums up the private inputs of clients and obtains the result without learning anything about the individual inputs beyond what is implied by the final sum. Flamingo focuses on the multi-round setting found in federated learning in which many consecutive summations (averages) of model weights are performed to derive a good model. Previous protocols, such as Bell et al. (CCS '20), have been designed for a single round and are adapted to the federated learning setting by repeating the protocol multiple times. Flamingo eliminates the need for the per-round setup of previous protocols, and has a new lightweight dropout resilience protocol to ensure that if clients leave in the middle of a sum the server can still obtain a meaningful result. Furthermore, Flamingo introduces a new way to locally choose the so-called client neighborhood introduced by Bell et al. These techniques help Flamingo reduce the number of interactions between clients and the server, resulting in a significant reduction in the end-to-end runtime for a full training session over prior work. We implement and evaluate Flamingo and show that it can securely train a neural network on the (Extended) MNIST and CIFAR-100 datasets, and the model converges without a loss in accuracy, compared to a non-private federated learning system.

description: We study exclusive production of scalar $χ_{c0}\equiv χ_c(0^{++})$ and pseudoscalar $η_c$ charmonia states in proton-proton collisions at the LHC energies. The amplitudes for $gg \to χ_{c0}$ as well as for $gg \to η_c$ mechanisms are derived in the $k_{T}$-factorization approach. The $p p \to p p η_c$ reaction is discussed for the first time. We have calculated rapidity, transverse momentum distributions as well as such correlation observables as the distribution in relative azimuthal angle and $(t_1,t_2)$ distributions. The latter two observables are very different for $χ_{c0}$ and $η_c$ cases. In contrast to the inclusive production of these mesons considered very recently in the literature, in the exclusive case the cross section for $η_c$ is much lower than that for $χ_{c0}$ which is due to a special interplay of the corresponding vertices and off-diagonal UGDFs used to calculate the cross sections. We present the numerical results for the key observables in the framework of potential models for the light-front quarkonia wave functions. We also discuss how different are the absorptive corrections for both considered cases.

description: Complex patterns generated by the time evolution of a one-dimensional digitalized coupled map lattice are quantitatively analyzed. A method for discerning complexity among the different patterns is implemented. The quantitative results indicate two zones in parameter space where the dynamics shows the most complex patterns. These zones are located on the two edges of an absorbent region where the system displays spatio-temporal intermittency.

description: The concept of multifunctionality of fishing activities is emerging, as fishery activities do not only provide commodity goods but have others functions (environmental, social, territorial, etc.). We choose to focus on the provision of amenities, such as the presence of fishing boats or direct sales of seafood, for which there is a demand that partly conditions the individual choices of visit on the coastline. We used choice experiments to estimate willingness to pay for these amenities produced jointly by commercial fishing. The empirical study was conducted on a sample of one thousand people we surveyed along the coasts of French Channel and of the North Sea.

description: A megújuló energiaforrások széles körű alkalmazása a környezetkímélő energiaellátás és a (hosszú távon kimutatható) költségmegtakarítás révén jelentős hatással lehet az életminőségre. Azonban ma még a megújuló energetikai technológiák nem teszik lehetővé a széles körű elterjedést, mivel a fajlagos beruházási költségek magasak. Remélhető viszont, hogy a költségek folyamatosan csökkenthetők lesznek, és a megújuló energiaforrások kihasználásával jelentkező kedvező környezeti hatások és a megtakarítások az életminőség javulásának irányába hatnak. ------------------ A wide use of renewable energy resources could significantly affect the quality of life because they would provide environment friendly energy at cost saving prices (detectable on long term basis). However, the application of renewable energy resources cannot be widely expanded at present, because specific investment costs into the technology involved is prohibitively expensive. Hopefully costs can be continually reduced and the exploitation of renewable energy resources will affect the environment and energy costs in a way that will lead to improvements in the quality of life.
The Structure of Magnetocentrifugal Winds I. Steady Mass Loading

description: We present the results of a series of time-dependent numerical simulations of cold, magnetocentrifugally launched winds from accretion disks. Our simulations span four and half decades of mass loading; in the context of a disk with a launching region from $0.1\AU$ to $1.0\AU$ around a $1\solarmass$ star and a field strength of about $20\gauss$ at the inner disk edge, this amounts to mass loss rates of $1\times 10^{-9}$ -- $3\times 10^{-5}\solarmassyear$ from each side of the disk. We find that the degree of collimation of the wind increases with mass loading; however even the ``lightest'' wind simulated is significantly collimated compared with the force-free magnetic configuration of the same magnetic flux distribution. The implication is that for flows from young stellar objects a radial field approximation is inappropriate. Surprisingly, the terminal velocity of the wind and the magnetic lever arm are still well-described by the analytical solutions for a radial field geometry. We also find that the isodensity contours and Alfvén surface are very nearly self-similar in mass loading. The wind becomes unsteady above some critical mass loading rate. For a small enough injection speed, we are able to obtain the first examples of a class of heavily-loaded magnetocentrifugal winds with magnetic fields completely dominated by the toroidal component all the way to the launching surface.

description: Using the theory of large deviations, we analyze the phase transition structure of the Curie-Weiss-Potts spin model, which is a mean-field approximation to the Potts model. This analysis is carried out both for the canonical ensemble and the microcanonical ensemble. Besides giving explicit formulas for the microcanonical entropy and for the equilibrium macrostates with respect to the two ensembles, we analyze ensemble equivalence and nonequivalence at the level of equilibrium macrostates, relating these to concavity and support properties of the microcanonical entropy. The Curie-Weiss-Potts model is the first statistical mechanical model for which such a detailed and rigorous analysis has been carried out.

title: Investigating the impact of climate change, land use change, and their interactions on forest loss in India
Creators: name: Haughan, Alice
Publisher: name: University of Reading
Year: 2024

description: Climate and land use change are the two main drivers of biodiversity loss worldwide. Forests, 
particularly tropical forests, host a disproportionate amount of terrestrial biodiversity. However, there 
remains a substantial research bias towards temperate regions and Amazonia when assessing the joint 
impacts of climate and land use change. Climate and land use change have been shown to interact,
leading to complex and unexpected ecological responses, as such this bias could be leading to a 
misrepresentation of the threats to tropical forests across Asia and Africa. India, a country not 
previously considered, presents a unique opportunity to explore the potential for interactions between 
the two drivers. India is predicted to experience increases in temperature, variable rainfall and 
prevalence of extreme events, at the same time as rapid population expansion. Analysis of forest trends 
in the country were prevalent in the 1990’s and the primary driver of loss was agricultural expansion. 
However, there are substantial knowledge gaps including the recent trends in forest change and the 
current primary driver of forest loss. Additionally, the effects of climate change on forests in the country 
have been largely overlooked. This thesis uses global datasets and mixed modelling approaches to 
explore the effects of climate change, land use change and their interactions across India during 1995-
2019. Results show, for the first time, that climate change has played a role in forest loss in India, 
however, the predominant driver of forest loss remains agricultural-driven land use changes. This 
research provides the first evidence of a synergistic interaction between drought and land use change
in the country, where the two drivers are leading to a greater area of forest loss. This research aslo
significantly contributes to the increased knowledge of the drivers of forest loss in India and highlights 
a concerning interaction that is predicted to worsen with time. These results have key implications for 
future management of the forests, which do not currently take climate change into account, and 
highlight that interactions between climate and land use change are occurring in Asian tropical forests.

description: We present the result of a search for orphan Gamma-Ray Burst (GRB) afterglows in the Pan-STARRS1 (PS1) COSMOS survey. There is extensive theoretical and observational evidence suggesting that GRBs are collimated jets; the direct observation of orphan GRB afterglows would further support this model. An optimal survey strategy is designed by coupling the PS1 survey with the Subaru/Hyper-Suprime-Cam (HSC) survey. The PS1 COSMOS survey, one of the survey fields in the PS1 Medium Deep Survey (PS1/MDS), searches a field of 7 deg$^2$ from December 2011 to January 2014, reaching a limiting magnitude R $\sim$ 23. The dense cadence of PS1/MDS is crucial for identifying transients, and the deep magnitude reached by the HSC survey (R $\sim$ 26) is important for evaluating potential GRB hosts. A transient classification method is employed to select potential orphan GRB afterglow candidates. After a thorough analysis of the transient and host galaxy properties, we conclude that there are no candidates in this survey field. The null result implies that the consideration of jet structures is essential for further orphan GRB afterglow surveys.
