Transverse emittance dilution due to coupler kicks in linear accelerators

description: One of the main concerns in the design of low emittance linear accelerators (linacs) is the preservation of beam emittance. Here we discuss one possible source of emittance dilution, the coupler kick, due to transverse electromagnetic fields in the accelerating cavities of the linac caused by the power coupler geometry. In addition to emittance growth, the coupler kick also produces orbit distortions. It is common wisdom that emittance growth from coupler kicks can be strongly reduced by using two couplers per cavity mounted opposite each other or by having the couplers of successive cavities alternation from above to below the beam pipe so as to cancel each individual kick. We therefore analyze consequences of alternate coupler placements. We show here that for sufficiently large Q values, alternating the coupler location from before to after the cavity leads to a cancellation of the orbit distortion but not of the emittance growth, whereas alternating the coupler location from before and above to behind and below the cavity cancels the emittance growth but not the orbit distortion. These compensations hold even when each cavity is individually detuned, e.g. by microphonics. Another effective method for reducing coupler kicks that is studied is the optimization of the phase of the coupler kick. This technique is independent of the coupler geometry but relies on operating on crest. A final technique studied is symmetrization of the cavity geometry in the coupler region with the addition of a stub opposite the coupler, which reduces the amplitude of the off axis fields and is thus effective for off crest acceleration as well. We show applications of these techniques to the energy recovery linac (ERL) planned at Cornell University.

Ancestral Sequence Reconstruction: From Chemical Paleogenetics to Maximum Likelihood Algorithms and Beyond
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2021

description: As both a computational and an experimental endeavor, ancestral sequence reconstruction remains a timely and important technique. Modern approaches to conduct ancestral sequence reconstruction for proteins are built upon a conceptual framework from journal founder Emile Zuckerkandl. On top of this, work on maximum likelihood phylogenetics published in Journal of Molecular Evolution in 1996 was one of the first approaches for generating maximum likelihood ancestral sequences of proteins. From its computational history, future model development needs as well as potential applications in areas as diverse as computational systems biology, molecular community ecology, infectious disease therapeutics and other biomedical applications, and biotechnology are discussed. From its past in this journal, there is a bright future for ancestral sequence reconstruction in the field of evolutionary biology.

description: For seven years, the EROS-2 project obtained a mass of photometric data on variable stars. We present a peculiar Cepheid-like star, in the direction of the Small Magellanic Cloud, which demonstrates unusual photometric behaviour over a short time interval. We report on data of the photometry acquired by the MARLY telescope and spectroscopy from the EFOSC instrument for this star, called EROS2 J005135-714459(sm0060n13842), which resembles the unusual Cepheid HR 7308. The light curve of our target is analysed using the Analysis of Variance method to determine a pulsational period of 5.5675 days. A fit of time-dependent Fourier coefficients is performed and a search for proper motion is conducted. The light curve exhibits a previously unobserved and spectacular change in both mean magnitude and amplitude, which has no clear theoretical explanation. Our analysis of the spectrum implies a radial velocity of 104 km s$^{-1}$ and a metallicity of -0.4$\pm$0.2 dex. In the direction of right ascension, we measure a proper motion of 17.4$\pm$6.0 mas yr$^{-1}$ using EROS astrometry, which is compatible with data from the NOMAD catalogue. The nature of EROS2 J005135-714459(sm0060n13842) remains unclear. For this star, we may have detected a non-zero proper motion for this star, which would imply that it is a foreground object. Its radial velocity, pulsational characteristics, and photometric data, however, suggest that it is instead a Cepheid-like object located in the SMC. In such a case, it would present a challenge to conventional Cepheid models.

description: Recent findings suggest that rooftop greenhouses could be more efficient when combined with waste streams in buildings, but there is a gap in quantification of the combined performance of building integrated greenhouses. This paper addresses this deficit for school buildings in London, UK, where urban agriculture is of increasing interest. A building energy simulation (BES) of an archetype school building is developed in EnergyPlus and co-simulated with a validated greenhouse energy simulator (GES). The performance of different greenhouse-building coupling configurations is evaluated to estimate the potential for crop growth, heat recovery and reduction in ventilation demand, through a sensitivity analysis and parametric study. Our results show that a 250 m2 greenhouse on the top floor of the school could produce 6t lettuce with half the energy demand of the same standalone greenhouse. Trade-offs across increase in humidity, yields, and energy efficiency indicate the importance of modelling to ensure optimal designs.
The importance of the olfactory system in human well-being, through nutrition and social behavior
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2021

description: The human sense of smell is still much underappreciated, despite its importance for vital functions such as warning and protection from environmental hazards, eating behavior and nutrition, and social communication. We here approach olfaction as a sense of well-being and review the available literature on how the sense of smell contributes to building and maintaining well-being through supporting nutrition and social relationships. Humans seem to be able to extract nutritional information from olfactory food cues, which can trigger specific appetite and direct food choice, but may not always impact actual intake behavior. Beyond food enjoyment, as part of quality of life, smell has the ability to transfer and regulate emotional conditions, and thus impacts social relationships, at various stages across life (e.g., prenatal and postnatal, during puberty, for partner selection and in sickness). A better understanding of how olfactory information is processed and employed for these functions so vital for well-being may be used to reduce potential negative consequences.

Abstract- As applications become more data centric, the cost of accessing data from memory dominates energy and throughput. An emerging paradigm to address this is in-memory computing.  Early approaches show the potential to reduce energy-delay product (EDP) by 2-to-3 orders of magnitude. However, architectures for enabling computation within the constrained structure of memory raise new challenges and opportunities. This tutorial will map out advances in these areas and examine recent demonstrations.
Bio - Naveen Verma received the B.A.Sc. degree in Electrical and Computer Engineering from the UBC, Vancouver, Canada, in 2003, and the M.S. and Ph.D. degrees in Electrical Engineering from MIT in 2005 and 2009, respectively. Since July 2009, he has been with the Department of Electrical Engineering at Princeton, where he is currently an Associate Professor. His research focuses on advanced sensing systems and on exploring how systems for learning, inference, and action planning can be enhanced by algorithms that exploit new sensing and computing technologies. This includes research on large-area, ?exible sensors, energy-ef?cient statistical-computing architectures and circuits, and machine-learning and statistical-signal-processing algorithms.
On the mechanism of action of glucose-dependent insulinotropic polypeptide
Creators: name: Dahl, Marshall Andrew
Publisher: name: University of British Columbia
Year: 2010

description: The interaction of the intestinal insulinotropic hormone GIP (Glucose-dependent Insulinotropic Polypeptide or Gastric Inhibitory Polypeptide) with the stimulus-secretion coupling mechanism of glucose-induced insulin secretion was investigated using the isolated, perfused, rat pancreas technique. The action of GIP in potentiating insulin secretion which had been initiated by a number of metabolic compounds other than glucose (D-glycer-aldehyde, 2-ketoisocaproate, L-leucine + L-glutamine) and the concentration-dependent nature of this action led to the formulation of the hypothesis that the insulinotropic effect of GIP required prior oxidation of these insulin-stimulating metabolites. It was therefore likely that the mechanism whereby GIP potentiated glucose-induced insulin secretion required an interaction located at a level involving effects secondary to glucose degradation in the B-cell. This effect may have required an intact N-terminus on the GIP molecule since a GIP₃-₄₂ homologue, which lacked the N-terminal Tyrosine-Alanine, possessed greatly diminished insulinotropic activity. Additional biological actions of GIP were suggested by the stimulation by the hormone of pancreatic somatostatin release and of the release of lipoprotein lipase-like activity from isolated rat adipocytes. A technique using reversed phase high pressure liquid chromatography (HPLC) was developed allowing the purification and fodination-state analysis of a pure bioactive ¹²⁵I-GIP molecule. Preliminary investigations of receptor binding activity of this purified ¹²⁵I-GIP to isolated rat adipocytes were also performed.

description: A group of non-uniform quantum lattice Hamiltonians in one dimension is introduced, which is related to the hyperbolic $1 + 1$-dimensional space. The Hamiltonians contain only nearest neighbor interactions whose strength is proportional to $\cosh j λ$, where $j$ is the lattice index and where $λ\ge 0$ is a deformation parameter. In the limit $λ\to 0$ the Hamiltonians become uniform. Spacial translation of the deformed Hamiltonians is induced by the corner Hamiltonians. As a simple example, we investigate the ground state of the deformed $S = 1/2$ Heisenberg spin chain by use of the density matrix renormalization group (DMRG) method. It is shown that the ground state is dimerized when $λ$ is finite. Spin correlation function show exponential decay, and the boundary effect decreases with increasing $λ$.

description: 47. Chydorus cf. sphaericus (Müller, 1776)
Localities and specimens found: 96 – 1♀; 98 – 1♀.
Distribution and ecology. Chydorus sphaericus s. lat. is one of the most known members of the chydorids, representing a cosmopolitan complex of closely related species with an intricate taxonomic history, many synonyms and, as previously thought, subspecies (Smirnov 1971, 1996; Belyaeva & Taylor 2009; Kotov et al. 2013 a, 2016; Karabanov et al. 2022; WoRMS Editorial Board 2024). Chydorus sphaericus -like populations are well known in the Oriental and adjacent territories (Chiang & Du 1979; Michael & Sharma 1988; Maiphae et al. 2008; Chatterjee et al. 2013; Korovchinsky 2013; Ji et al. 2015; Sinev et al. 2020), including Vietnam, where these crustaceans were often indicated as the subspecies Ch. sphaericus sphaericus (Müller, 1776) (Shirota 1966; Dang et al. 1980, 2002; Dang & Ho 2001; Phan et al. 2015).
Chydorus sphaericus is considered to be a wide eurybiont, living in water bodies and habitats of different kinds (Fryer 1968). In addition to the open and vegetated littoral areas, it is often found in the open pelagic zone (in plankton). In the latter case, the crustacean can attach to various floating substrates, such as algae and detritus (Smirnov 1971, 1996; Korovchinsky et al. 2021b). In our material, two Ch. sphaericus -like females were found in a mountain river in winter, during the period of moderate current, low water and, in comparison with lowland areas, low temperature (see Appendix 1).
Remarks. Despite the long history of this taxon, the Ch. sphaericus group of species still remains incompletely investigated. Recent studies, including molecular-genetic, have revealed that the “typical” form, Ch. sphaericus s. str., is found mainly in the western and central Palearctic (together with other related forms), not counting cases of anthropogenic or other introductions outside this region. In turn, in other parts of the world the Ch. sphaericus -like populations are obviously represented by sibling species, some of which have already been examined and described whereas others remain to be studied in detail (Belyaeva & Taylor 2009; Klimovsky & Kotov 2015; Kotov et al., 2016; Karabanov et al. 2022). It has not yet been precisely established which specific forms of the Ch. sphaericus group inhabit Southeast Asia.

description: This paper presents a novel system of data-driven approaches for simulating the dynamics of electricity demand profiles. Demand profiles of individual dwellings are decomposed into deterministic (e.g. ‘Trends’ and ‘Seasonal’) and stochastic (‘remainder’) components using the STL (a Seasonal-Trend decomposition procedure based on Loess) approach. Stochastic components are modelled using a Hidden Markov Model (HMM) and combined with deterministic components to generate synthetic demand profiles. To simulate extreme (peak) demand, the synthetic profiles were post-processed using a Generalised Pareto (GP) distribution, and a percentile-based bias-correction scheme. All the techniques are systematically coupled into a hybrid system, referred to as ‘STL_HMM_GP’. The STL_HMM_GP system is thoroughly accessed and validated by comparing a range of statistical characteristic of observed and simulated profiles for three case study communities. The potentials of the STL_HMM_GP system is demonstrated for simulating aggregated demand profiles, generated using an accessible small sample of observed individual demand profiles.

description: © 2021 by the authors. Cancer is one of the primary causes of death worldwide. Tumour malignancy is related to tumor heterogeneity, which has been suggested to be due to a small subpopulation of tumor cells named cancer stem cells (CSCs). CSCs exert a key role in metastasis development, tumor recurrence, and also epithelial-mesenchymal transition, apoptotic resistance, self-renewal, tumorigenesis, differentiation, and drug resistance. Several current therapies fail to eradicate tumors due to the ability of CSCs to escape different programmed cell deaths. Thus, developing CSC-selective and programmed death-inducing therapeutic approaches appears to be of primary importance. In this review, we discuss the main programmed cell death occurring in cancer and the promising CSC-targeting agents developed in recent years. Even if the reported studies are encouraging, further investigations are necessary to establish a combination of agents able to eradicate CSCs or inhibit their growth and proliferation.

Subjects: cardiorespiratory fitness

description: © Introduction Patients with diabetes are at greater risk of hospital readmission than patients without diabetes. There is a need to identify more modifiable risk factors for readmission as potential targets for intervention. Cardiorespiratory fitness is a predictor of morbidity and mortality. The purpose of this study was to examine whether there is an association between exercise capacity based on the maximal workload achieved during treadmill stress testing and readmission among patients with diabetes. Research design and methods This retrospective cohort study included adult patients with diabetes discharged from an academic medical center between July 1, 2012 and December 31, 2018 who had a stress test documented before the index discharge. Univariate analysis and multinomial multivariable logistic regressions were used to evaluate associations with readmission within 30 days, 6 months, and 1 year of discharge. Exercise capacity was measured as metabolic equivalents (METs). Results A total of 580 patients with 1598 hospitalizations were analyzed. Mean METs of readmitted patients were significantly lower than for non-readmitted patients (5.7 (2.6) vs 6.7 (2.6), p<0.001). After adjustment for confounders, a low METs level (<5) was associated with higher odds of readmission within 30 days (OR 5.46 (2.22-13.45), p<0.001), 6 months (OR 2.78 (1.36-5.65), p=0.005), and 1 year (OR 2.16 (1.12-4.16), p=0.022) compared with medium (5-7) and high (>7) METs level. During the 6.5-year study period, patients with low METs had a mean of 3.2±3.6 hospitalizations, while those with high METs had 2.5±2.4 hospitalizations (p=0.007). Conclusions Lower exercise capacity is associated with a higher risk of readmission within 30 days, 6 months, and 1 year, as well as a greater incidence of hospitalization, in patients with diabetes. Future studies are needed to explore whether exercise reduces readmission risk in this population.

description: On a K-unstable toric variety we show the existence of an optimal destabilising convex function. We show that if this is piecewise linear then it gives rise to a decomposition into semistable pieces analogous to the Harder-Narasimhan filtration of an unstable vector bundle. We also show that if the Calabi flow exists for all time on a toric variety then it minimises the Calabi functional. In this case the infimum of the Calabi functional is given by the supremum of the normalised Futaki invariants over all destabilising test-configurations, as predicted by a conjecture of Donaldson.

description: © 2020 The Authors. Obesity Science & Practice published by World Obesity and The Obesity Society and John Wiley & Sons Ltd. Background: Despite plausibility of migraine headaches contributing to impaired sexual function among women, data are inconsistent and point to obesity as a potential confounder. Prospective studies that assess the relative importance of migraine improvements and weight loss in relation to sexual function could help elucidate associations among migraine, obesity and female sexual dysfunction (FSD). Objective: To evaluate sexual function changes and predictors of improvement after behavioural weight loss (BWL) intervention for migraine or migraine education (ME). Methods: Women with migraine and overweight/obesity were randomized to 16 weeks of BWL (n = 54) or ME (n = 56). Participants completed a 4-week smartphone headache diary and the Female Sexual Function Index (FSFI) at pre- and post-treatment. A validated FSFI total cut-off score defined FSD. We compared changes in FSFI scores and FSD rates between conditions and evaluated migraine improvements and weight loss as predictors of sexual functioning in the full sample. Results: Among treatment completers (n = 85), 56 (65.9%) participants who reported sexual activity at pre- and post-treatment were analysed. Migraine improvements were similar between conditions, whereas BWL had greater weight losses compared with ME. FSD rates did not change overall (48.2% to 44.6%, p =.66) or by condition (BWL: 56.0% to 40.0% vs. ME: 41.9% to 48.4%, p =.17). Similar patterns were observed for changes in FSFI total and subscale scores. Across conditions, larger weight losses predicted greater improvements in FSFI total and arousal subscale scores, whereas larger migraine headache frequency reductions predicted greater improvements in FSFI satisfaction subscale scores. Conclusion: Sexual functioning did not improve with either BWL or ME despite migraine headache improvements in both conditions and weight loss after BWL. However, weight loss related to improvements in physiological components of the sexual response (i.e., arousal) and overall sexual functioning, whereas reduced headache frequency related to improved sexual satisfaction. Additional research with larger samples is needed.

Abstract - Applications, such as autonomous driving, rely on the perception of the environment around us based on extensive sensing. While most signals in the nature are not changing quickly and can be captured with relatively low-bandwidth sensors, most require low-noise sensors. This tutorial goes over the main sources of noise with a focus on capacitive and image sensors. Advanced noise-reduction circuit techniques, such as chopping, correlated-double sampling, and Boxcar sampling, are explained.

description: © Copyright © 2020 Eisdorfer, Smit, Keefe, Lemay, Smith and Spence. Spinal cord injury (SCI) often results in life-long sensorimotor impairment. Spontaneous recovery from SCI is limited, as supraspinal fibers cannot spontaneously regenerate to form functional networks below the level of injury. Despite this, animal models and humans exhibit many motor behaviors indicative of recovery when electrical stimulation is applied epidurally to the dorsal aspect of the lumbar spinal cord. In 1976, epidural stimulation was introduced to alleviate spasticity in Multiple Sclerosis. Since then, epidural electrical stimulation (EES) has been demonstrated to improve voluntary mobility across the knee and/or ankle in several SCI patients, highlighting its utility in enhancing motor activation. The mechanisms that EES induces to drive these improvements in sensorimotor function remain largely unknown. In this review, we discuss several sensorimotor plasticity mechanisms that we hypothesize may enable epidural stimulation to promote recovery, including changes in local lumbar circuitry, propriospinal interneurons, and the internal model. Finally, we discuss genetic tools for afferent modulation as an emerging method to facilitate the search for the mechanisms of action.
Signature change from Schutz's canonical quantum cosmology and its classical analogue

description: We study the signature change in a perfect fluid Friedmann-Robertson-Walker quantum cosmological model. In this work the Schutz's variational formalism is applied to recover the notion of time. This gives rise to a Schrodinger-Wheeler-DeWitt equation with arbitrary ordering for the scale factor. We use the eigenfunctions in order to construct wave packets and evaluate the time-dependent expectation value of the scale factor which coincides with the ontological interpretation. We show that these solutions exhibit signature transitions from a finite Euclidean to a Lorentzian domain. Moreover, such models are equivalent to a classical system where, besides the perfect fluid, a repulsive fluid is present.

Pattern separation and pattern completion: Behaviorally separable processes?

Publisher: name: My University
Year: 2020
Subjects: Pattern separation

Lure classification
Holistic recollection
Episodic memory

description: © 2020, The Author(s). Episodic memory capacity requires several processes, including mnemonic discrimination of similar experiences, termed pattern separation, and holistic retrieval of multidimensional experiences given a cue, termed pattern completion. Both computations seem to rely on the hippocampus proper, but they also seem to be instantiated by distinct hippocampal subfields. Thus, we investigated whether individual differences in behavioral expressions of pattern separation and pattern completion were correlated after accounting for general mnemonic ability. Young adult participants learned events comprised of a scene-animal-object triad. In the pattern separation task, we estimated mnemonic discrimination using lure classification for events that contained a similar lure element. In the pattern completion task, we estimated holistic recollection using dependency in retrieval success for different associations from the same event. Although overall accuracies for the two tasks correlated as expected, specific measures of individual variation in holistic retrieval and mnemonic discrimination did not correlate, suggesting that these two processes involve distinguishable properties of episodic memory.

Fragmentation contribution to the transverse single-spin asymmetry in proton-proton collisions

Year: 2013
Subjects: hep-ph

description: Within the collinear twist-3 framework, we study the single-spin asymmetry (SSA) in collisions between unpolarized protons and transversely polarized protons with focus on the fragmentation term. The fragmentation mechanism must be analyzed in detail in order to unambiguously determine the impact of various contributions to SSAs in hadron production. Such a distinction may also settle the "sign mismatch" between the transverse SSA in proton-proton collisions and the Sivers effect in semi-inclusive deep inelastic scattering. We calculate terms involving quark-quark and quark-gluon-quark correlators, which is an important step in such an investigation. © 2013 Elsevier B.V.

The role of allelic variation in the management of fishes
Creators: name: Gauldie, Robert William
Publisher: name: University of British Columbia
Year: 2010

description: The thesis consists of four papers that deal with the development of a biologically reasonable role for protein alleles in fisheries management. Paper 1: The need for an understanding of the biological properties of protein alleles is established by arguments that the neutral theory of alleliccvariation is an effective null hypothesis to the Fisher/Haldane/Wright definition of selection, but not a legitimate explanation for allelic variation in its own right. The literature demonstrating physiological differences between alleles in fish is reviewed. General biochemical and various ecological arguments are put forward to support the empirical evidence for significant physiological differences between alleles. The three main empirical arguments of neutral theorists, the segregational load argument, the molecular clock analogy, and the correlation between polymorphism and the molecular weight of proteins, have had a great influence on practical analysis and experimental design of fisheries management experiments in allele frequency. The validity of these empirical arguments is questioned. Statistical problems associated with the neutralist usage of allelic variation in fisheries management are briefly reviewed. Paper 2: Transferrin alleles are widely used in fisheries management as neutral markers. The biological role of transferrin alleles is reviewed and the effects of the biological properties and the statistical use of transferrin variants are discussed. Paper 3: The biological role of alleles requires some relationship between allelic variants and the parameters of fisheries management models before allelic variation can be assigned a practical role in fisheries management. Such a relationship is demonstrated between allelic genotypes at the phosphoglucomutase locus in liver and growth in the fish Cheilodactylus macropterus. Arguments are also presented for a significant change in allele frequency in this species due to fishing pressure. Paper 4: A biological role of alleles in fisheries management that is based on physiological differences between alleles may require an extensive understanding of the physiology and biochemistry of the fish before the allelic variation can be put to any practical use. Experimental data are presented to show that the metals Fe, Zn, P, Sr, and Na in the fish otolith reflect the ambient temperature. Thus an individual temperature life-history of a fish may be found in the otolith providing one, of the important experimental parameters necessary to understanding the biochemical and physiological role of allelic variants. The thesis concludes with a brief and general overview of fisheries management models and the reasons why the biological role of allelic variation is pertinent to these models.
Interfacial enhancement of ferroelectricity in CaTiO3/BaTiO 3 superlattices

Publisher: name: My University
Year: 2011
Subjects: cond-mat.mtrl-sci

description: We carry out first-principles calculations for CaTiO3/BaTiO 3superlattices with epitaxial strain corresponding to growth on a SrTiO3 substrate, and consider octahedral rotations as well as ferroelectric distortions. The calculations are done as a function of electric displacement field, and both a macroscopic and a local electrostatic analysis are carried out. We find that strong octahedral rotations occur for TiO 6 octahedra sandwiched between CaO layers on both sides, but are strongly suppressed if either neighboring layer is a BaO layer. Due to the resulting enhancement of the ferroelectric instability in these octahedra, we find that overall the ferroelectric instability of the superlattice is enhanced by the interface. Thus, short-period superlattices in this system have a larger ferroelectric polarization than longer-period ones of the same average composition, contrary to the expected trend. © 2011 American Physical Society.
