description: Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)
The fluid force acting on a hand is known to be crucial in swimming, especially for the crawl, backstroke and butterfly strokes. In swimming research, pressure sensors attached to swimmers’ hands have often been employed to measure the fluid forces during swimming. On the other hand, the swimming humanoid robot SWUMANOID was developed as an experimental platform for swimming research. Since the robot has the half‐scaled body, the conventional pressure sensors for actual swimmers are too large to attach to the robot. In this present study, a custom hand with embedded pressure sensors was developed. A preliminary experiment was conducted to confirm the feasibility of the developed system

description: Aim: We establish the mean metallicity from high-resolution spectroscopy for the recently found dwarf spheroidal galaxy Bootes I and test whether it is a common feature for ultra-faint dwarf spheroidal galaxies to show signs of inhomogeneous chemical evolution (e.g. as found in the Hercules dwarf spheroidal galaxy). Methods: We analyse high-resolution, moderate signal-to-noise spectra for seven red giant stars in the Bootes I dSph galaxy using standard abundance analysis techniques. In particular, we assume local thermodynamic equilibrium and employ spherical model atmospheres and codes that take the sphericity of the star into account when calculating the elemental abundances. Results: We confirm previous determinations of the mean metallicity of the Bootes I dwarf spheroidal galaxy to be -2.3 dex. Whilst five stars are clustered around this metallicity, one is significantly more metal-poor, at -2.9 dex, and one is more metal-rich at, -1.9 dex. Additionally, we find that one of the stars, Boo-127, shows an atypically high [Mg/Ca] ratio, indicative of stochastic enrichment processes within the dSph galaxy. Similar results have previously only been found in the Hercules and Draco dSph galaxies and appear, so far, to be unique to this type of galaxy.

description: Aims Cardiac resynchronization therapy (CRT) improves functional status, induces reverse left ventricular remodelling, and reduces hospitalization and mortality in patients with symptomatic heart failure, left ventricular systolic dysfunction, and QRS prolongation. However, the impact of iron deficiency on CRT response remains largely unclear. The purpose of the study was to assess the effect of functional and absolute iron deficiency on reverse cardiac remodelling, clinical response, and outcome after CRT implantation. Methods and results The relation of iron deficiency and cardiac resynchronization therapy response (RIDE-CRT) study is a prospective observational study. We enrolled 77 consecutive CRT recipients (mean age 71.3 ± 10.2 years) with short-term follow-up of 3.3 ± 1.9 months and long-term follow-up of 13.0 ± 3.2 months. Primary endpoints were reverse cardiac remodelling on echocardiography and clinical CRT response, assessed by change in New York Heart Association classification. Echocardiographic CRT response was defined as relative improvement of left ventricular ejection fraction ≥ 20% or left ventricular global longitudinal strain ≥ 20%. Secondary endpoints were hospitalization for heart failure and all-cause mortality (mean follow-up of 29.0 ± 8.4 months). At multivariate analysis, iron deficiency was identified as independent predictor of echocardiographic (hazard ratio 4.97; 95% confidence interval 1.15–21.51; P = 0.03) and clinical non-response to CRT (hazard ratio 4.79; 95% confidence interval 1.30–17.72, P = 0.02). We found a significant linear-by-linear association between CRT response and type of iron deficiency (P = 0.004 for left ventricular ejection fraction improvement, P = 0.02 for left ventricular global longitudinal strain improvement, and P = 0.003 for New York Heart Association response). Iron deficiency was also significantly associated with an increase in all-cause mortality (P = 0.045) but not with heart failure hospitalization. Conclusions Iron deficiency is a negative predictor of effective CRT therapy as assessed by reverse cardiac remodelling and clinical response. Assessment of iron substitution might be a relevant treatment target to increase CRT response and outcome in chronic heart failure patients.

description: We report on two optical realizations of the $1 \to 2$ asymmetric phase-covariant cloning machines for polarization states of single photons. The experimental setups combine two-photon interference and tunable polarization filtering that enables us to control the asymmetry of the cloners. The first scheme involves a special unbalanced bulk beam splitter exhibiting different splitting ratios for vertical and horizontal polarizations, respectively. The second implemented scheme consists of a balanced fiber coupler where photon bunching occurs, followed by a free-space part with polarization filters. With this later approach we were able to demonstrate very high cloning fidelities which are above the universal cloning limit.

Geodesic focussing in parallel-plate systems
Creators: name: Mosevich, Jack Walter
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with the mathematics of the design of parallel-plate equivalents of optical systems, in particular with the parallel-plate equivalent of the parabolic mirror. A parallel-plate microwave system consists of a pair of metal plates, not necessarily plane, which are parallel in the sense that they share common normals at every point, and the normal separation is constant throughout. Consider the mean surface M , which is the locus of midpoints of the double normals, and suppose that microwave radiation is fed into the region between the plates. If M is not excessively curved the rays travel along its geodesies and a natural problem arises of how to shape M so that all rays from a point source between the plates emerge in a parallel beam (thus the system is equivalent to a parabolic mirror). It is assumed that M consists of two flats connected by a focusing bend B , where B is part of a tubular surface with directrix Δ . The problem is to determine the curve Δ so that the geodesies on the tube generated by Δ satisfy the focusing condition. The exact mathematical formulation of this problem yields an extremely involved functional differential equation in terms of the polar equation of Δ, r = r(θ) , which proves unsuitable for solving for r(θ) . Methods are developed by which an approximate solution is given in terms of an implicit non-linear integro-differential equation in r(θ) . This equation also proves too involved to solve exactly, but numerical approximations are calculated by two different schemes. One scheme is an analog of Euler's method, and the other is based on Galerkin's method of undetermined coefficients. The problem is so involved that analytical error analysis appears too difficult to handle. The best that can be achieved at this time is to calculate numerically the deviation of a beam from true parallelism. The results prove to be encouraging, the maximum deviation from true parallell of a geodesic was 6/10 of one degree, at the periphery of the system. The necessary modifications of these methods for solving other optical problems are also taken up.

description: We present results of Niobium based SQUID magnetometers for which the weak-links are engineered by the local oxidation of thin films using an Atomic Force Microscope (AFM). Firstly, we show that this technique allows the creation of variable thickness bridges with 10 nm lateral resolution. Precise control of the weak-link milling is offered by the possibility to realtime monitor weak-link conductance. Such a process is shown to enhance the magnetic field modulation hence the sensitivity of the magnetometer. Secondly, AFM lithography is used to provide a precise alignment of NanoSQUID weak-links with respect to a ferromagnetic iron dot. The magnetization switching of the near-field coupled particle is studied as a junction of the applied magnetic field direction.

description: BACKGROUND: Variants of the desmosomal protein desmoplakin are associated with arrhythmogenic cardiomyopathy, an important cause of ventricular arrhythmias in children and young adults. Disease penetrance of desmoplakin variants is incomplete and variant carriers may display noncardiac, dermatologic phenotypes. We describe a novel cardiac phenotype associated with a truncating desmoplakin variant, likely causing mechanical instability of myocardial desmosomes. METHODS AND RESULTS: In 2 young brothers with recurrent myocarditis triggered by physical exercise, screening of 218 cardiomyopathy-related genes identified the heterozygous truncating variant p.Arg1458Ter in desmoplakin. Screening for infections yielded no evidence of viral or nonviral infections. Myosin and troponin I autoantibodies were detected at high titers. Immunohistology failed to detect any residual DSP protein in endomyocardial biopsies, and none of the histologic criteria of arrhythmogenic cardiomyopathy were fulfilled. Cardiac magnetic resonance imaging revealed no features associated with right ventricular arrhythmogenic cardiomyopathy, but multifocal subepicardial late gadolinium enhancement was present in the left ventricles of both brothers. Screening of adult cardiomyopathy cohorts for truncating variants identified the rare genetic variants p.Gln307Ter, p.Tyr1391Ter, and p.Tyr1512Ter, suggesting that over subsequent decades critical genetic/exogenous modifiers drive pathogenesis from desmoplakin truncations toward different end points. CONCLUSIONS: The described novel phenotype of familial recurrent myocarditis associated with a desmoplakin truncation in adolescents likely represents a serendipitously revealed subtype of arrhythmogenic cardiomyopathy. It may be caused by a distinctive adverse effect of the variant desmoplakin upon the mechanical stability of myocardial desmosomes. Variant screening is advisable to allow early detection of patients with similar phenotypes.

description: We use UV/optical and X-ray observations of 272 radio-quiet Type 1 AGNs and quasars to investigate the CIV Baldwin Effect (BEff). The UV/optical spectra are drawn from the Hubble Space Telescope, International Ultraviolet Explorer and Sloan Digital Sky Survey archives. The X-ray spectra are from the Chandra and XMM-Newton archives. We apply correlation and partial-correlation analyses to the equivalent widths, continuum monochromatic luminosities, and alpha_ox, which characterizes the relative X-ray to UV brightness. The equivalent width of the CIV 1549 emission line is correlated with both alpha_ox and luminosity. We find that by regressing l_UV with EW(CIV) and alpha_ox, we can obtain tighter correlations than by regressing l_UV with only EW(CIV). Both correlation and regression analyses imply that l_UV is not the only factor controlling the changes of EW(CIV); alpha_ox (or, equivalently, the soft X-ray emission) plays a fundamental role in the formation and variation of CIV. Variability contributes at least 60% of the scatter of the EW(CIV)-l_UV relation and at least 75% of the scatter of the of the EW(CIV)-alpha_ox relation. In our sample, narrow Fe Kalpha 6.4 keV emission lines are detected in 50 objects. Although narrow Fe Kalpha exhibits a BEff similar to that of CIV, its equivalent width has almost no dependence on either alpha_ox or EW(CIV). This suggests that the majority of narrow Fe Kalpha emission is unlikely to be produced in the broad emission-line region. We do find suggestive correlations between the emission-line luminosities of CIV and Fe Kalpha, which could be potentially used to estimate the detectability of the Fe Kalpha line of quasars from rest-frame UV spectroscopic observations.

description: This study investigates why some immigrants choose names for their children that are common in their home country whereas others opt for names used by natives in the host country. Drawing on the sociological literature on symbolic boundaries, the first strategy can be described as boundary-maintenance whereas the second can be classified as boundary-crossing. Using data from the German Socio-Economic Panel Study and applying bivariate and multivariate methods, two broader explanations for name-giving practices are tested: (1) cultural proximity and the permeability of the symbolic boundary between home and host country; and (2) immigrants’ levels of linguistic, structural, social, and emotional integration in the host country. Overall, the theoretical model explains the differences very satisfactorily. Whilst both sets of factors proved relevant to immigrants’ name-giving practices, the immigrants’ level of integration in the host country was less important than the cultural proximity between the origin group and host country.
Irreducible representations of algebras

Publisher: name: University of British Columbia
Year: 2011

description: An element x of an associative algebra A is called diagonable provided A has a basis of characteristic vectors for the transformation ad x: a → ax - xa of A. This notion immediately generalizes to that of a diagonable subspace L of A. The centralizer A[sub O] of L plays an important role in the representation theory of A, for there is a one-to-one correspondence between the "λ-weighted" irreducible modules of A and of A[sub O]. In Chapters Two and Three, we first explore various ring-theoretic properties of A and A[sub O], and then use the results obtained to classify the diagonable elements in different algebras. We also give conditions under which all A-modules are weighted. The Cartan theory of Lie and Jordan algebras is linked in Chapter Four by the observation that Cartan subalgebras of simple finite dimensional Lie and Jordan algebras (over algebraically closed fields of characteristic 0) are diagonable subspaces of the respective universal enveloping algebras. Furthermore, in the Jordan case, the centralizer of a Cartan subalgebra is the centralizer of one of its elements and is a direct sum of complete matrix rings. Finally, we are able to show that the universal enveloping algebra of any simple Jordan algebra which contains an idempotent whose Peirce one-space is one-dimensional, is generated by its idempotents.

description: Aims: It is largely unknown whether cancer patients seen in routine care show ventricular arrhythmias in 24 h electrocardiograms (ECGs), and whether when they are detected they carry prognostic relevance. Methods and Results: We included 261 consecutive cancer patients that were referred to the department of cardiology for 24 h ECG examination and 35 healthy controls of similar age and sex in the analysis. To reduce selection bias, cancer patients with known left ventricular ejection fraction <45% were not included in the analysis. Non-sustained ventricular tachycardia (NSVT) episodes of either >= 3 and >= 4 beats duration were more frequent in cancer patients than controls (17% vs. 0%, p = 0.0008; 10% vs. 0%, p = 0.016). Premature ventricular contractions (PVCs)/24 h were not more frequent in cancer patients compared to controls (median (IQR), 26 (2-360) vs. 9 (1-43), p = 0.06; >= 20 PVCs 53% vs. 37%, p = 0.07). During follow-up, (up to 7.2 years, median 15 months) of the cancer patients, 158 (61%) died (1-/3-/5-year mortality rates: 45% [95%CI 39-51%], 66% [95%CI 59-73%], 73% [95%CI 64-82%]). Both non-sustained ventricular tachycardia of >= 4 beats and >= 20 PVCs/24 h independently predicted mortality in univariate and multivariate survival analyses, adjusted for all other univariate predictors of mortality as well as relevant clinical factors, including cancer stage and type, performance status (ECOG), prior potentially cardiotoxic anti-cancer drug therapy, coronary artery disease, potassium concentration, and haemoglobin (multivariate adjusted hazard ratios: NSVT >= 4 beats [HR 1.76, p = 0.022], >= 20 PVCs/24 h [HR 1.63, p < 0.0064]). Conclusions: NSVT >= 4 beats and >= 20 PVCs/day seen in routine 24 h ECGs of patients with cancer carry prognostic relevance.

description: Flavin semiquinones are common intermediate redox states in flavoproteins, and thus, knowledge of their electronic structure is essential for fully understanding their chemistry and chemical versatility. In this contribution, we use a combination of high-field electron nuclear double resonance spectroscopy and selective deuterium labeling of flavin mononucleotide (FMN) with subsequent incorporation as cofactor into a variant Avena sativa LOV domain to extract missing traits of the electronic structure of a protein-bound FMN radical. From these experiments, precise values of small proton hyperfine and deuterium nuclear quadrupole couplings could be extracted. Specifically, isotropic hyperfine couplings of −3.34, −0.11, and +0.91 MHz were obtained for the protons H(6), H(9), and H(7α), respectively. These values are discussed in the light of specific protein–cofactor interactions. Furthermore, the temperature behavior of the H(7α) methyl-group rotation elicited by its energy landscape was analyzed in greater detail. Pronounced interplay between the two methyl groups at C(7) and C(8) of FMN could be revealed. Most strikingly, this rotational behavior could be modulated by selective deuterium editing.

description: With a median patient survival of 15 months, glioblastoma (GBM) is still one of the deadliest malign tumors. Despite immense efforts, therapeutic regimens fail to prolong GBM patient overall survival due to various resistance mechanisms. Chemokine signaling as part of the tumor microenvironment plays a key role in gliomagenesis, proliferation, neovascularization, metastasis and tumor progression. In this review, we aimed to investigate novel therapeutic approaches targeting various chemokine axes, including CXCR2/CXCL2/IL-8, CXCR3/CXCL4/CXCL9/CXCL10, CXCR4/CXCR7/CXCL12, CXCR6/CXCL16, CCR2/CCL2, CCR5/CCL5 and CX3CR1/CX3CL1 in preclinical and clinical studies of GBM. We reviewed targeted therapies as single therapies, in combination with the standard of care, with antiangiogenic treatment as well as immunotherapy. We found that there are many antagonist-, antibody-, cell- and vaccine-based therapeutic approaches in preclinical and clinical studies. Furthermore, targeted therapies exerted their highest efficacy in combination with other established therapeutic applications. The novel chemokine-targeting therapies have mainly been examined in preclinical models. However, clinical applications are auspicious. Thus, it is crucial to broadly investigate the recently developed preclinical approaches. Promising preclinical applications should then be investigated in clinical studies to create new therapeutic regimens and to overcome therapy resistance to GBM treatment.

description: We have constrained unparticle interactions with neutrinos and electrons using available data on neutrino-electron elastic scattering and the four CERN LEP experiments data on mono photon production. We have found that, for neutrino-electron elastic scattering, the MUNU experiment gives better constraints than previous reported limits in the region d>1.5. The results are compared with the current astrophysical limits, pointing out the cases where these limits may or may not apply. We also discuss the sensitivity of future experiments to unparticle physics. In particular, we show that the measurement of coherent reactor neutrino scattering off nuclei could provide a good sensitivity to the couplings of unparticle interaction with neutrinos and quarks. We also discuss the case of future neutrino-electron experiments as well as the International Linear Collider.

H* and some rather nice spaces

Publisher: name: University of British Columbia

description: The Problem The integral cohomology algebra functor, H*, was introduced to algebraic topology in hopes of deciding when spaces are homotopy-equivalent. With this in mind, let T(A) ≃{ X|H* (X) ≃ A} , the collection of all simply-connected finite complexes X , for which the cohomology algebra H* (X) is isomorphic to A . We ask: when are there only a finite number of homotopy equivalence classes in T(A) ? The Result Let A satisfy the condition: [See Thesis for Equation] Then there are only a finite number of homotopy-equivalence classes in T(A) . The Methods For a given A we construct a "model space" M and show that for any X ε T(A) there exists a continuous map X [sup θ/sub →]M "within N" . The concept of a map within N is less restrictive than that of a homotopy-equivalence, but more restrictive than the concept of a rational equivalence. We then show that in the category T[sup N]/M , whose objects are [sup θ/sub →] , maps within N , having range M , there are only a finite number of equivalence classes. This is proved with the use of Postnikov Towers and algebraic arguments similar to Serre's mod C theory. The result then follows. Applications The result applies to spaces having rational cohomology isomorphic to the rational cohomology of topological groups, H-spaces, Stiefel manifolds, the complex, and quaternlonic projective spaces and of some other homogeneous spaces.
Mg spin affects adenosinetriphosphate activity

description: The Schlegel-Frisch ab initio molecular dynamics (ADMP) (DFT:B3LYP), T = 310 K, is used to study complexation between adenosinetriphosphate (ATP), ATP subsystem, and magnesium cofactor [Mg(H2O)6]2+, Mg subsystem, in a water pool, modeled with 78 water molecules, in singlet (S) and triplet (T) states. The computations prove that the way of ATP cleavage is governed by the electron spin of Mg. In the S state Mg prefers chelation of γ-β-phosphate oxygens (O1-O2), whereas in the T state it chelates β-α-phosphate oxygens (O2-O3) or produces a single-bonded intermediate. Unlike the chelates, which initiate ionic reaction paths, the single-bonded intermediate starts off a free-radical path of ATP cleavage, yielding a highly reactive adenosinemonophosphate ion-radical, .AMP-, earlier observed in the CIDNP (Chemically Induced Dynamic Nuclear Polarization) experiment (A.A. Tulub, 2006). The free-radical path is highly sensitive to Mg nuclear spin, which through a hyperfine interaction favors the production of unpaired electron spins. The unique role of Mg in ATP cleavage comes through its ability to serve as a unique redox center, initially accepting an electron from ATP and then giving it back to products. Redox activity of Mg differs for T and S states and affects the number of coordinated water molecules. The findings give a new insight into the NTP (N = nucleoside) energetics and assembly of NTP-operating molecules, including proteins.

description: Surfactant-free multifunctional semiconductor-metallic nanostructures possessing several modalities are formed due to laser-induced structural modification of pure silicon nanoparticles in the presence of gold. It results to variable size-dependent chemical composition examined by energy-dispersive X-ray spectroscopy. Laser-synthesized silicon-based nanocomposites exhibit remarkable both plasmonic and paramagnetic properties. Their plasmonic maxima are found to be easily adjusted in the whole visible spectral range. Influence of resonant laser irradiation on spin behaviour of silicon-gold nanoparticles is established. Their spin–lattice and spin–spin relaxation processes are investigated as well. Such multifunctional nanoparticles can reveal a huge potential for different applications in field of nanomedicine, in particular, for biosensing and bioimaging.

description: We establish a new type of local asymptotic formula for the Green's function ${\mathcal G}_t(x,y)$ of a uniformly parabolic linear operator $\partial_t - L$ with non-constant coefficients using dilations and Taylor expansions at a point $z=z(x,y)$, for a function $z$ with bounded derivatives such that $z(x,x)=x \in {\mathbb R}^N$. For $z(x,y) =x$, we recover the known, classical expansion obtained via pseudo-differential calculus. Our method is based on dilation at $z$, Dyson and Taylor series expansions, and the Baker-Campbell-Hausdorff commutator formula. Our procedure leads to an elementary, algorithmic construction of approximate solutions to parabolic equations which are accurate to arbitrary prescribed order in the short-time limit. We establish mapping properties and precise error estimates in the exponentially weighted, $L^{p}$-type Sobolev spaces $W^{s,p}_a({\mathbb R}^N)$ that appear in practice.

description: В настоящее время наблюдается весьма сложный период развития общественных отношений в мировом сообществе, оказывающий существенное влияние и на формирование государственной политики России, в том числе демонстрирующий необходимость трансформации целей и постановки обновленных задач по вопросам энергетической безопасности, которые приобретают первостепенное государственное значение. Реализация поставленных перед государством задач безусловно обеспечивается посредством правовых норм, формируемых в рамках правовой политики государства. Государственная правовая политика выражается и определяется в документах стратегического планирования. При этом государственная правовая политика в области энергетической безопасности должна контекстно форматироваться в общую систему государственной правовой политики. Основным специализированным документом стратегического планирования в области энергетической безопасности является Доктрина энергетической безопасности. В этой связи представляется актуальным анализ формирования государственной правовой политики в области энергетической безопасности, в частности исследование Доктрины энергетической безопасности на предмет наличия в ней положений, системно определяющих государственную правовую политику, а также выявление взаимосвязи с иными документами стратегического планирования, определяют смысл и содержание данной работы. Данное исследование может быть полезно студентам, аспирантам и докторантам, занимающимся вопросами энергетической безопасности, а также способствовать решению фундаментальной научной задачи по выработке наиболее эффективной модели государственной правовой политики в сфере энергетической безопасности.

description: Aims How often a medical article is cited is important for many people because it is used to calculate different variables such as the h-index and the journal impact factor. The aim of this analysis was to assess how the citation count varies between Web of Science (WoS), Scopus, and Google Scholar in the current literature. Methods We included the top 50 cited articles of four journals ESC Heart Failure; Journal of cachexia, sarcopenia and muscle; European Journal of Preventive Cardiology; and European Journal of Heart Failure in our analysis that were published between 1 January 2016 and 10 October 2019. We recorded the number of citations of these articles according to WoS, Scopus, and Google Scholar on 10 October 2019. Results The top 50 articles in ESC Heart Failure were on average cited 12 (WoS), 13 (Scopus), and 17 times (Google Scholar); in Journal of cachexia, sarcopenia and muscle 37 (WoS), 43 (Scopus), and 60 times (Google Scholar); in European Journal of Preventive Cardiology 41 (WoS), 56 (Scopus), and 67 times (Google Scholar); and in European Journal of Heart Failure 76 (WoS), 108 (Scopus), and 230 times (Google Scholar). On average, the top 50 articles in all four journals were cited 41 (WoS), 52 (Scopus, 26% higher citations count than WoS, range 8–42% in the different journals), and 93 times (Google Scholar, 116% higher citation count than WoS, range 42–203%). Conclusion Scopus and Google Scholar on average have a higher citation count than WoS, whereas the difference is much larger between Google Scholar and WoS.
Machine learning for security and security for machine learning

Publisher: name: Imperial College London

description: In this thesis we analyse test time adversarial examples for machine learning in security domains. First, we consider adversarial examples for autoregressive machine learning models employed for intrusion detection. We consider industrial control systems (ICS) as a use case, and develop attack algorithms which can successfully overcome the domain specific challenges found in ICS. We test our attack on a ICS dataset and demonstrate that an adversary can evade state of the art intrusion detection systems. Secondly, we analyse threats posed in federated learning which offer adversaries new ways to subvert defensive algorithms. Specifically, we are interested in the interaction of adversarial training with federated learning. To that end, we examine adversarial training when under convergence attacks, and when subject to a novel attack objective which stealthily produces a brittle version of adversarial training. We perform initial validation on benchmark image datasets, and then consider malware detection as a security domain in which there is strong motivation to use federated learning. For our final contribution, we switch to the defender's perspective and develop an algorithm called Deep Latent Defence. Our algorithm analyses the intermediate representation of data as it travels through a neural network. We show this offers strong defensive performance even against adaptive adversaries.

The large-scale structure of the Saturnian magnetosphere
Creators: name: Staniland, Ned
Publisher: name: Imperial College London
Year: 2021

description: The Cassini mission offered a unique opportunity to study the global characteristics of Saturn and its magnetosphere due to its significant spatial and temporal coverage. The mission that spanned almost half a Saturnian year covered elements of both seasons and two solar cycles. Now it is complete we can better understand how the magnetosphere of Saturn evolves over time and can identify what the key drivers are that shape its large-scale structure. A global stress state of the Saturnian magnetosphere is determined to identify when the system is compressed, expanded, or near its ground state. The magnetic field is found to exhibit an underlying local time asymmetry, where the field is more compressed at dusk and expanded at dawn. The system remains close to its ground state throughout the Cassini era, but examples of significant perturbations to the system are identified, revealing a highly variable global structure. The thickness of the magnetodisc current sheet that is populated by plasma sourced from the moon Enceladus is determined using fast, steep crossings of the current layer. A local time and radial structure are found that reflect the different particle motions and field responses due to magnetopause confinement. These results are essential for developing models of the Saturnian system and highlight the importance of incorporating local time variability when analysing data. The lack of an observed cushion region in the outer magnetosphere of Saturn has been a mystery since this region exists at Jupiter and the two share similar features. Using the entire Cassini orbital dataset, we find that this phenomenon does occur but that it is rare, finding only a handful of examples. The evidence of a cushion forming at dusk at Saturn rather than dawn, as it is at Jupiter, reveals significant differences in configuration and dynamics between these two systems.
Upper critical field Hc2 in Bechgaard salts (TMTSF)2PF6

description: The symmetry of the superconductivity in Bechgaard salts is still unknown, though the triplet pairing has been established by Hc2 and NMR for (TMTSF)2PF6. The large upper critical field at T = 0K (Hc2 ~ 5 Tesla) both for H || a and H || b also indicates strongly the triplet pairing. Here we start with a low energy effective Hamiltonian and study the temperature dependence of the corresponding Hc2(T)'s. The present analysis suggests that one chiral f-wave superconductor should be the most likely candidate near the upper critical field.

Ultrafast spectroscopy of chl-a and chl-f containing photosystems I and II of oxygenic photosynthesis
Creators: name: Zamzam, Noura
Publisher: name: Imperial College London
Year: 2021

description: Plants, algae, and cyanobacteria sustain life on Earth by using sunlight energy to produce oxygen and biomass via oxygenic photosynthesis. It involves water splitting and carbon fixation using the protein complexes photosystem II (PSII) and photosystem I (PSI), respectively. Despite tremendous advances in the field, the dynamics and mechanisms of the underlying processes are not fully understood yet. Ultrafast spectroscopy methods have been particularly versatile in uncovering a lot of detail about these processes; however, the spectral overlap arising from identical pigments has always been a complication. An opportunity to overcome that came along with the recent discovery of red-shifted chlorophyll f (chl-f). In this work, energy and electron transfer processes of chl-f-containing PSII and PSI from far-red light (FRL)-grown Chrooccidiopsis thermalis PCC 7203 were studied using ultrafast visible and infrared spectroscopy, respectively, and comparisons with standard white light-grown photosystems were made. Sub-picosecond energy transfer from antenna chlorophyll a (chl-a) to far-red chlorophylls (chl-f/chl-d) was revealed in FRL-PSII with excitation being highly localised. The data supported a primary donor role of a far-red chlorophyll and a secondary donor role of chl-a at PD1 position, with an unprecedentedly delayed formation of PD1+•. In FRL-PSI, a complete energy transfer from chl-a to chl-f within 1 ps was observed. Spectral evolution supported a primary radical pair assignment to A-1+•A0-• with A-1 being a chl-f. Shifts in carbonyl bands corresponding to P700+•/P700 and A1-•/A1 indicated dielectric differences in FRL-PSI environment. Vibrational properties of chl-f and chl-a in the ground and excited states were studied using density functional theory at B3LYP/6-31G(d) and CAMB3LYP/6-31G(d) levels, with particular interest in carbonyl modes experimentally shown to significantly downshift upon excitation. These downshifts were underestimated by both methods and the calculated Franck-Condon and Herzberg-Teller vibrational progressions demonstrated inaccuracies in the prediction of high-frequency mode displacements.

description: We investigate the $x\log x$ condition for a general (Crump--Mode--Jagers) multi-type branching process with a general type space by constructing a size-biased population measure that relates to the ordinary population measure via an intrinsic martingale $W_t$. Sufficiency of the $x\log x$ condition for a non-degenerate limit of $W_t$ is proved and conditions for necessity are investigated.
