description: We consider the problem of efficient computation in the Jacobian of a hyperelliptic curve of genus 3 defined over a field whose characteristic is not 2. For curves with a rational Weierstrass point, fast explicit formulas are well known and widely available. Here we address the general case, in which we do not assume the existence of a rational Weierstrass point, using a balanced divisor approach.

description: We construct a price impact model between stocks in a correlated market. For the price change of a given stock induced by the short-run liquidity of this stock itself and of the information about other stocks, we introduce a self- and a cross-impact function of the time lag. We model the average cross-response functions for individual stocks employing the impact functions of the time lag, the impact functions of traded volumes and the trade-sign correlators. To quantify the self- and cross-impacts, we propose a construction to fix the parameters in the impact functions. These parameters are further corroborated by a diffusion function that measures the correlated motion of prices from different stocks. This construction is mainly ad hoc and alternative ones are not excluded. It turns out that both the sign cross- and self-correlators are connected with the cross-responses. The self- and cross-impact functions are indispensable to compensate amplification effects which are due to the sign correlators integrated over time. We further quantify and interpret the price impacts of time lag in terms of temporary and permanent components. To support our model, we also analyze empirical data, in particular the memory properties of the sign self- and average cross-correlators. The relation between the average cross-responses and the traded volumes which are smaller than their average is of power-law form.
BIOMARKERS OF XENO-OESTROGEN EXPOSURE IN DECAPOD CRUSTACEANS
Creators: name: SANDERS, MATTHEW BURTON
Publisher: name: University of Plymouth
Year: 2004

description: Many anthropogenic chemicals, most notably xeno-oestrogens, are known to have the potential to disrupt vertebrate endocrine systems. Induction of the female-specific protein vitellogenin (Vtg) in male fish, for example, is a well-known effect of exposure to xeno-oestrogens and serves as a biomarker of such exposure. There have been few comparable studies of putative biomarkers of endocrine disruption in decapods. The current study aimed to establish if reproduction and development of two decapods, the prawn, Palaemon elegans and the crab, Carcinus maenas, were affected following exposure to known oestrogenic chemicals and whether a biomarker approach, analogous to that for vertebrates, could be adopted. The xeno-oestrogen 4-n-nonylphenol (4-NP) was acutely toxic to P. elegans (48h-LC5o, 34.3-96.1 µg Lˉ¹) and C. maenas larvae (48h-LC50, 116-507.3 µg Lˉ¹ ), with P. elegans among the most sensitive species reported. Other than a small, but significant, increase in the mortality of P. elegans larvae exposed to 4-NP at 2 µg Lˉ¹ , neither 4-NP nor the natural oestrogen, 17β-oestradiol (E2) significantly affected growth, development or survival of P. elegans at environmentally realistic concentrations (<0.2-20 µg Lˉ¹ ). Similar results were obtained with C. maenas larvae, but they must be viewed with caution as survival, including that of the controls, was poor. Vitellin-like proteins were identified in the adults and larval stages of both P. elegans and C. maenas using polyclonal antisera to lipovitellin and apolipovitellin. Vtg was female-specific in both species and expression was restricted to females undergoing vitellogenesis. No induction of Vtg was observed in males, from either species, following laboratory exposure to E2, and 4-NP. Likewise, no Vtg was detected in the haemolymph of male C. maenas which had been collected from sites known to be contaminated with oestrogenic chemicals. The titres of the vitellin-like proteins in P. elegans larvae, determined using an indirect ELISA, were significantly affected, in a concentration-independent manner, following exposure to both E2 and 4- NP. Exposure to 4-NP, at 0.2-20 µg Lˉ¹ , resulted in a 5-18% increase in the levels of vitellin-like proteins. Exposure to E2, at 0.2 and 20 µg Lˉ¹ however, reduced levels by up to 11%. Further development of the ELISA is required to assess comparable effects in C. maenas larvae. Overall, while it remains questionable whether these effects result from endocrine disruption, an oestrogen receptor-mediated effect is unlikely. Increased mortality may have been due to toxic effects and no causal link has been established between the parent/exposure compounds and the induced alterations in protein profiles. This study emphasised the necessity for long term multi-faceted studies to determine the real impacts of pollutants at distinct organisational levels.
Elliptic Integrals for Calculation of the Propagation Time of a Signal, Emitted and Received by Satellites on One Orbit

description: The propagation time of a signal, emitted by a moving along an elliptical orbit satellite from the GPS (or GLONASS) satellite confi gurations is a very important ingredient of the theory, based on the formalism of the null cone and accounting for the effects of the General Relativity Theory. For the case of satellites, orbiting along a plane elliptic orbit, it has been proved that the propagation time for the signal between the satellites is given by a combination of elliptic integrals of the first, second and third kind. For the more general case of satellites on a space-distributed elliptic orbit, the propagation time is expressed by higher (fourth) order elliptic integrals, which according to the standard theory can be expressed recurrently by means of lower-order elliptic integrals. In the concrete case, the elliptic integrals of the second and the fourth order are expressed by means of a combination of irrational functions and the zero-order elliptic integral in the Legendre form. It has been proved that for the investigated case, second-order elliptic integrals can be expressed by elementary functions.

description: Significance: Optical neuroimaging has become a well-established clinical and research tool to monitor cortical activations in the human brain. It is notable that outcomes of functional Near-InfraRed Spectroscopy (fNIRS) studies depend heavily on the data processing pipeline and classification model employed. Recently, Deep Learning (DL) methodologies have demonstrated fast and accurate performances in data processing and classification tasks across many biomedical fields. Aim: We aim to review the emerging DL applications in fNIRS studies. Approach: We first introduce some of the commonly used DL techniques. Then the review summarizes current DL work in some of the most active areas of this field, including brain-computer interface, neuro-impairment diagnosis, and neuroscience discovery. Results: Of the 63 papers considered in this review, 32 report a comparative study of deep learning techniques to traditional machine learning techniques where 26 have been shown outperforming the latter in terms of classification accuracy. Additionally, 8 studies also utilize deep learning to reduce the amount of preprocessing typically done with fNIRS data or increase the amount of data via data augmentation. Conclusions: The application of DL techniques to fNIRS studies has shown to mitigate many of the hurdles present in fNIRS studies such as lengthy data preprocessing or small sample sizes while achieving comparable or improved classification accuracy.

description: We study in this work the dynamics of a granular impurity immersed in a low-density granular gas of identical particles. For description of the kinetics of the granular gas and the impurity particles we use the rough hard sphere collisional model. We take into account the effects of non-conservation of energy upon particle collision. We find an (approximate) analytical solution of the pertinent kinetic equations for the single-particle velocity distribution functions that reproduces reasonably well the properties of translational/rotational energy non-equipartition. We assess the accuracy of the theoretical solution by comparing with computer simulations. For this, we use two independent computer data sets, from molecular dynamics (MD) and from Direct Simulation Monte Carlo method (DSMC). Both approach well, with different degrees, the kinetic theory within a reasonable range of parameter values.

description: Ein zunehmend wichtiges Anliegen von Unternehmen ist es, zeitnah auf Nachfragen zu reagieren. Erwerbstätige sollen im Rahmen von Rufbereitschaft bei Bedarf verfügbar sein. Rufbereitschaft ist eine Art Hindergrunddienst, der den Arbeitnehmer dazu verpflichtet, auf Abruf die Arbeit aufzunehmen. Sie können sich an einem Ort ihrer Wahl aufhalten, müssen diesen aber dem Arbeitgeber mitteilen oder vom Arbeitgeber jederzeit erreichbar sein. Rufbereitschaft erfolgt für festzulegende Phasen im Rahmen eines Arbeitsverhältnisses (Bundesarbeitsgericht, 2000). Auf Grundlage der wenigen Literatur zur Wirkung von Rufbereitschaft, lassen sich Hinweise ableiten, dass Rufbereitschaft mit erhöhtem Stress, Beeinträchtigung des Schlafs und der psychischen Gesundheit einhergeht (Nicol/Botterill 2004). Allerdings weisen die Studien zum Teil zahlreiche Mängel auf. Sie wurden zumeist im Querschnittsdesign durchgeführt, Verlaufsstudien bilden die Ausnahme. Häufig bleibt unklar, was mit Rufbereitschaft (engl. on-call) gemeint ist. Die Verwendung dieses Begriffes ist vor allem international uneinheitlich (vgl. Carley 2007). In dem Beitrag soll in einem Review die bisherige Forschung zum Themenbereich Rufbereitschaft systematisiert werden und um eigene Forschungsergebnisse ergänzt werden.

description: A minimal model based on the Co-varying Physical Couplings (CPC) framework for gravity is proposed. The CPC framework is based on the assumptions of a metric-compatible four-dimensional Riemannian manifold where a covariantly conserved stress-energy tensor acts as source of the field equations which are formally the same as Einstein field equations, but where the couplings $\{ G, c,Λ\}$ are allowed to vary simultaneously. The minimal CPC model takes $Λ$ as a genuine constant while $c$ and $G$ vary in an entangled way that is consistent with Bianchi identity and the aforementioned assumptions. The model is constrained using the most recent galaxy cluster gas mass fraction observational data. Our result indicates that the functions $c(z)$ and $G\left(z\right)=G_{0}\left(c/c_{0}\right)^{4}$ are compatible with constant couplings for the three different parameterizations of $c=c(z)$ adopted here.

description: Since all Einstein spacetimes are vacuum solutions to quadratic gravity in four dimensions, in this paper we study various aspects of non-Einstein vacuum solutions to this theory. Most such known solutions are of traceless Ricci and Petrov type N with a constant Ricci scalar. Thus we assume the Ricci scalar to be constant which leads to a substantial simplification of the field equations. We prove that a vacuum solution to quadratic gravity with traceless Ricci tensor of type N and aligned Weyl tensor of any Petrov type is necessarily a Kundt spacetime. This will considerably simplify the search for new non-Einstein solutions. Similarly, a vacuum solution to quadratic gravity with traceless Ricci type III and aligned Weyl tensor of Petrov type II or more special is again necessarily a Kundt spacetime. Then we study the general role of conformal transformations in constructing vacuum solutions to quadratic gravity. We find that such solutions can be obtained by solving one non-linear partial differential equation for a conformal factor on any Einstein spacetime or, more generally, on any background with vanishing Bach tensor. In particular, we show that all geometries conformal to Kundt are either Kundt or Robinson-Trautman, and we provide some explicit Kundt and Robinson-Trautman solutions to quadratic gravity by solving the above mentioned equation on certain Kundt backgrounds.

description: Nucleases derived from the prokaryotic defense system CRISPR-Cas are frequently re-purposed for gene editing and molecular diagnostics. Hence, an in-depth understanding of the molecular mechanisms of these enzymes is of crucial importance. We focused on Cas12a from Francisella novicida (FnCas12a) and investigated the functional role of helix 1, a structural element that together with the bridge helix (BH) connects the recognition and the nuclease lobes of FnCas12a. Helix 1 is structurally connected to the lid domain that opens upon DNA target loading thereby activating the active site of FnCas12a. We probed the structural states of FnCas12a variants altered in helix 1 and/or the bridge helix using single-molecule FRET measurements and assayed the pre-crRNA processing, cis- and trans-DNA cleavage activity. We show that helix 1 and not the bridge helix is the predominant structural element that confers conformational stability of FnCas12a. Even small perturbations in helix 1 lead to a decrease in DNA cleavage activity while the structural integrity is not affected. Our data, therefore, implicate that the concerted remodeling of helix 1 and the bridge helix upon DNA binding is structurally linked to the opening of the lid and therefore involved in the allosteric activation of the active site.

The Chiral Induced Spin Selectivity Effect -- What It Is, What It Is Not, And Why It Matters

description: The chiral induced spin selectivity effect is an excited states phenomenon, which can be probed using photo-spectroscopy as well as transport measurements. On the one hand such measurements represent averaged quantities, on the other hand nearly all theoretical descriptions, with only a few exceptions, have been concerned with energy dependent properties of the pertinent structures. While those properties may or may not be relevant for the chiral induced spin selectivity effect, many of those properties have been attributed as being the, or part of the, origins of the effect. Here, it is demonstrated that, for instance, the spin-resolved transmission provides little, if any, information about the chiral induced spin selectivity effect. Moreover, although effective single-electron theory can be used in this context, reasons are given for why such descriptions are not viable.

We analyze two examples: regular QCD where we calculate the "four quark" vacuum condensate and a preon composite model based on QCD at higher scales. In this context we also determine the number of flavors at which the second chiral and confinement phase transitions occur and discuss the consequences.

description: Reported are the results of a 6 year study of adolescent self-esteem. This study observed a group of students from Year 10 to their third year after leaving the secondary school system. In that 6 year period, the subjects were tested 3 times using the Coopersmith Self -Esteem Inventory (1975). Both the Adult and School Forms were used. The students attended both single sex and coeducational schools in their junior secondary years and then attended a common coeducational college for the Years 11 and 12. Their self-esteem levels showed no gender effect in Year 10, but when tested in Year 12, the self-esteem of the whole group had declined noticeably. In 1993, the group of 81 students was recontacted for the final testing with the SEI. Only 20 responded. The SEI of those 20 students over the three testings indicated that the group of 20 had not changed its self-esteem level from 1988. It is possible that the use of questionnaires and written surveys as opposed to face to face contact resulted in an atypical group as its self-esteem levels and Tertiary Entrance Score was higher than average. The group showed no relationship between its academic ability and self-esteem, there was no gender effect in any area including subject choice in Years 11 and 12 and in choice of university course and generally the subjects' estimates of their self-esteem was in accord with the score on the SEI. The question of the reason for the decline of self-esteem of the 81 students in Year 12 remains and may not be observable in the light of significant changes in school environments. It is possible that gender differences if they were significant at any time may have diminished because of programs and general interest in the issue.

description: We continue our study on corrections from canonical quantum gravity to the power spectra of gauge-invariant inflationary scalar and tensor perturbations. A direct canonical quantization of a perturbed inflationary universe model is implemented, which leads to a Wheeler-DeWitt equation. For this equation, a semiclassical approximation is applied in order to obtain a Schroedinger equation with quantum-gravitational correction terms, from which we calculate the corrections to the power spectra. We go beyond the de Sitter case discussed earlier and analyze our model in the first slow-roll approximation, considering terms linear in the slow-roll parameters. We find that the dominant correction term from the de Sitter case, which leads to an enhancement of power on the largest scales, gets modified by terms proportional to the slow-roll parameters. A correction to the tensor-to-scalar ratio is also found at second order in the slow-roll parameters. Making use of the available experimental data, the magnitude of these quantum-gravitational corrections is estimated. Finally, the effects for the temperature anisotropies in the cosmic microwave background are qualitatively obtained.

description: This paper proposes energy-efficient coordinated beamforming strategies for multi-cell multi-user multiple-input single-output system. We consider a practical power consumption model, where part of the consumed power depends on the base station or user specific data rates due to coding, decoding and backhaul. This is different from the existing approaches where the base station power consumption has been assumed to be a convex or linear function of the transmit powers. Two optimization criteria are considered, namely network energy efficiency maximization and weighted sum energy efficiency maximization. We develop successive convex approximation based algorithms to tackle these difficult nonconvex problems. We further propose decentralized implementations for the considered problems, in which base stations perform parallel and distributed computation based on local channel state information and limited backhaul information exchange. The decentralized approaches admit closed-form solutions and can be implemented without invoking a generic external convex solver. We also show an example of the pilot contamination effect on the energy efficiency using a heuristic pilot allocation strategy. The numerical results are provided to demonstrate that the rate dependent power consumption has a large impact on the system energy efficiency, and, thus, has to be taken into account when devising energy-efficient transmission strategies. The significant gains of the proposed algorithms over the conventional low-complexity beamforming algorithms are also illustrated.

description: A pair of neutral atoms separated by several microns and prepared in identical s-states of large principal quantum number experience a van der Waals interaction. If microwave fields are used to generate a superposition of s-states with different principal quantum numbers, a null point may be found at which a specific superposition state experiences no van der Waals interaction. An application of this novel Rydberg state in a quantum controlled-Z gate is proposed, which takes advantage of GHz rate transitions to nearby Rydberg states.

Electrogenerated chemiluminescence (ECL), the generation of light emitting states by means of electron transfer between electrochemically generated precursors continues to grow in importance as the basis for highly sensitive analytical techniques. Studies of ECL systems also provide valuable insights into the principles underpinning the operation of organic light-emitting devices (OLEDs) and light emitting electrochemical cells (LEECs) which operate under a similar mechanism. Commercial ECL systems are all based on tris(2,2'-bipyridine)ruthenium(II) ([Ru(bpy)3] 2+) or closely related derivatives. Moreover, the vast majority of research in this area has focused on ruthenium complexes of this type. This is surprising considering the relatively low luminescent quantum yields and limited wavelength tuneability of such complexes, (eg. [Ru(bpy)3] 2+ shows only ~4% quantum efficiency in aqueous media). New materials possessing tunable emission wavelengths and higher quantum efficiencies would significantly enhance the sensitivity and selectivity of current ECL detection systems. The broad objective of the work presented in this thesis is to discover new ECL luminophores outside the realm of ruthenium, evaluate their properties and suggest new avenues of exploration for ECL systems. The novel complexes explored in this work are based on the metal atoms of platinum, iridium and cadmium. Through variation of metal centres and coordinating ligands, we demonstrate the ability to tune the energetics of the reaction leading to the emitting state, tune the energy of the excited state itself and most importantly, increase our understanding of these systems and their potential for ECL application. A range of photophysical and electrochemical techniques have been used to explore the relationship between the photophysical and redox properties of the new transition metal complexes. The findings provide insights into the characteristics required for efficient ECL and suggest new directions in the search for novel ECL luminophores.

description: A stable physical system has an energy spectrum that is bounded from below. For quantum systems, the dangerous states of unboundedly low energies should decouple and become null. We propose the principle of nullness and apply it to the bootstrap study of Hermitian and non-Hermitian anharmonic oscillators.

Reappraisal of the minimal flavoured $Z^{\prime}$ scenario

description: Recent results from the intensity frontier indicate the tantalizing possibility of violation in lepton flavour universality. In light of this we revisit the minimal phenomenological $Z'$ model taking in account both vectorial and axial-vectorial flavour violating couplings to the charged leptons. We make a systematic study to identify the minimal framework that can simultaneously explain the recent results on anomalous magnetic moment of muon and electron while remaining in consonance with $R_{K^{(*)}}$, $B^0_s-\bar{B^0_s}$ mixing and angular observables in the $B^+\to K^{+*} μ^+μ^-$ channel reported by the LHCb collaboration. We demonstrate that the neutrino trident data imply a further ${\rm SU(2)}_L$ violation in the leptonic couplings of the exotic $Z'$.

Estuaries as Sources of Methylated Arsenic to the North Sea
Creators: name: Kitts, Heather Jane
Publisher: name: University of Plymouth
Year: 1991

description: Analytical techniques were developed for the detection of inorganic arsenic (As(III) and As(V)), monomethylarsenic (MMA) and dimethylarsenic (DMA) in water, pore waters, suspended particles and bed sediments of the Humber Estuary, Thames Estuary and the southern North Sea. Dissolved inorganic As in the Humber Estuary showed removal in the mouth of the estuary in association with an Fe-rich outfall. Intertidal sediments and suspended particles had elevated inorganic As concentrations in the vicinity of the As-rich outfall located in the low salinity zone. Particulate As had a distinct concentration gradient away from the estuary mouth, indicating the transport of As out of the estuary. The presence of MMA and DMA in the water column was attributed to the methylation of inorganic As by marine phytoplankton and was not detected when the seawater temperatures were below about 10° C DMA concentrations were higher than MMA. The Humber and the Thames Estuaries both had sources of inorganic As, but As methylation within the estuaries was not significant. MMA and DMA in the estuarine plumes and the North Sea showed strong seasonality, with concentrations below detection in winter, and maximum concentrations in late summer when the methylated As was 21% of the total As in the Humber and Thames Plumes. The concentrations of MMA and DMA in the early autumn (32% of the total dissolved As) were highest off the Dutch coast where the water temperatures were up to 18° C. There were no significant correlations between the methylated As and inorganic As, temperature, chlorophyll a nor phosphate. A water sample from a developing spring bloom was incubated and showed the removal of inorganic As at a rate of 0.04ugAs/l/day, but there was no subsequent increase in the dissolved organic species, indicating a delay interval between peak primary productivity and the release of MMA and DMA. Inorganic As was detected in the porewaters of the Humber and Thames Plumes. In late summer, MMA and DMA were found at equivalent concentrations in all the Humber Plume porewaters. Flux calculations indicated that the diffusion of inorganic As, MMA and DMA from the sediments into the water column was insignificant, largely as a result of low sediment porosity. However, a resuspension event caused a detectable increase in inorganic As at the bottom of the water column. The importance of this work to the development of the 3-D hydrodynamic model of the North Sea is discussed.
Quasidecoupled state for dark matter in nonstandard thermal histories

description: Dark matter drops out of kinetic equilibrium with standard model particles when the momentum-transfer rate equals the expansion rate. In a radiation-dominated universe, this occurs at essentially the same time as dark matter kinetically decouples from the plasma. Dark matter may also fall out of kinetic equilibrium with standard model particles during an early matter-dominated era (EMDE), which occurs when the energy content of the Universe is dominated by either a decaying oscillating scalar field or a semistable massive particle before big bang nucleosynthesis. Until now, it has been assumed that kinetic decoupling during an EMDE happens similarly to the way it does in a radiation-dominated era. We show that this is not the case. By studying the evolution of the dark matter temperature, we establish a quasidecoupled state for dark matter in an EMDE, during which the dark matter temperature cools faster than the plasma temperature but slower than it would cool if the dark matter were fully decoupled. The dark matter does not fully decouple until the EMDE ends and the Universe becomes radiation dominated. We also extend the criteria for quasidecoupling to other nonstandard thermal histories and consider how quasidecoupling affects the free-streaming length of dark matter.

Spatial Dynamics of Urban Growth Based on Entropy and Fractal Dimension

description: The fractal dimension growth of urban form can be described with sigmoid functions such as logistic function due to squashing effect. The sigmoid curves of fractal dimension suggest a type of spatial replacement dynamics of urban evolution. How to understand the underlying rationale of the fractal dimension curves is a pending problem. This study is based on two previous findings. First, normalized fractal dimension proved to equal normalized spatial entropy; second, a sigmoid function proceeds from an urban-rural interaction model. Defining urban space-filling measurement by spatial entropy, and defining rural space-filling measurement by information gain, we can construct a new urban-rural interaction and coupling model. From this model, we can derive the logistic equation of fractal dimension growth strictly. This indicates that urban growth results from the unity of opposites between spatial entropy increase and information increase. In a city, an increase in spatial entropy is accompanied by a decrease in urban land availability. An inference is that urban growth struggles between the force of urban space-filling and the force of urban space-saving. This work presents a set of urban models of spatial dynamics, which help us understand urban evolution from the angle of view of entropy and fractals.
