description: We present powder and single crystal X-ray diffraction data as evidence for a monoclinic distortion in the low spin (S=0) and intermediate spin state (S=1) of LaCoO3. The alternation of short and long bonds in the ab plane indicates the presence of eg orbital ordering induced by a cooperative Jahn-Teller distortion. We observe an increase of the Jahn-Teller distortion with temperature in agreement with a thermally activated behavior of the Co3+ ions from a low-spin ground state to an intermediate-spin excited state.

description: We propose a model for the universe based on Jordan algebras. The action consists of cubic terms with coefficients being the structure constants of a Jordan algebra. Coupling constants only enter the theory via symmetry breaking which also selects a physical vacuum. "Before" the symmetry breaking the universe is in a pre-geometric state where it makes no sense to talk about space or time, but time comes into existence with the symmetry breaking together with a Hamiltonian which can create space from "nothing" and in some cases can propagate the space to macroscopic size in a finite time. There exists symmetry breaking which results in macroscopic spacetime dimensions 3, 4, 6 and 10, based on the Jordan algebras of Hermitian 3x3 matrices with real, complex, quarternion and octonion entries,respectively.

description: Despite the obvious impact of the CFO and the CEO on a firm’s financial statements, there is limited empirical evidence on whether and how the personal characteristics of senior management are associated with earnings management. We provide empirical evidence on the relation between earnings management and the accounting and financial expertise of these C-suite managers. For a sample of S&P 500 firms we find that CEOs and CFOs with accounting and financial expertise appear to manage earnings more aggressively than CEOs and CFOs without such expertise. We document greater earnings management by C-suite managers with accounting/financial expertise via accruals as well as real activities, such as overproducing goods, cutting back on discretionary spending, such as advertising and research and development expenses, manipulating sales and shifting of core expenses to special items. Our findings have important implications for boards of directors, members of the audit committee, investors and others.

Decay of spin polarized hot carrier current in a quasi one-dimensional spin valve structure

description: We study the spatial decay of spin polarized hot carrier current in a spin-valve structure consisting of a semiconductor quantum wire flanked by half-metallic ferromagnetic contacts. The current decays because of D'yakonov-Perel' spin relaxation in the semiconductor caused by Rashba spin orbit interaction. The associated relaxation length is found to decrease with increasing lattice temperature (in the range 30-77 K) and exhibit a non-monotonic dependence on the electric field driving the current. The relaxation lengths are several tens of microns which are at least an order of magnitude larger than what has been theoretically calculated for two-dimensional structures at comparable temperatures, Rashba interaction strengths and electric fields. This improvement is a consequence of one-dimensional carrier confinement that does not necessarily suppress carrier scattering, but nevertheless suppresses D'yakonov-Perel' spin relaxation.

description: This paper describes the derivation of two production functions showing the dependence of maize grain yields on fertilization and rainfall. The data were taken from maize fertilizer trials conducted for eleven years at the Dundee Research Station. The mbdels lend themselves to economic analysis. Fertilization was represented by either applied nitrogen (N) and applied phosphate (Pa) or N and post fertilization P soil test (Pt) readings. The functions conform to the Law of Diminishing . 1.eturns, and show a- positive interidion-between the two nutrients. Total rainfall was determined for a pre-planting period and a sequence of consecutive growth stages, extending from sowing to physiological maturity. The models include linear rainfall terms and linear rainfall-nutrient interaction terms. The adjusted R2 values were 0,897 for the model using P applied, and 0,805 for the P soil test model.

In particular, we investigate the entanglement of a system of coupled harmonic oscillators. A simple form of entanglement criterion in terms of their interaction is found. It is shown that a pair of interacting ground state coupled oscillators are more likely to be entangled for weaker coupling strengths while coupled oscillators in excited states entangle at higher coupling strengths. Interacting oscillators are more likely to be entangled as their interaction increases.

Getting to the bottom line : An exploration of gender and earnings quality
Creators: name: Krishnan, Gopal V.

Publisher: name: American University
Year: 2023

description: For stakeholders, such as investors and lenders, to appropriately assess a company’s financial performance, the reported accounting earnings must closely reflect the economic reality of the organization’s financial activity throughout the reporting period. The degree to which reported earnings capture economic reality is called earnings quality. Managers have an ethical obligation to report high quality earnings to interested stakeholders in a timely matter. Accounting research has identified conditions within an organization, such as management compensation contracts and pending litigation that can impact earnings quality. We extend this line of research by exploring whether another characteristic of an organization, gender diversity in senior management, influences the quality of reported earnings. Companies with more women in senior management are found to be more profitable and have higher stock returns after initial public offerings than those with fewer women in the management ranks. Our findings suggest that the improved bottom line for companies with more women senior executives is not produced through the management of earnings or lower quality earnings. Instead, earnings quality is positively associated with gender diversity in senior management.

description: Abnormality detection is a challenging task due to the dependence on a specific context and the unconstrained variability of practical scenarios. In recent years, it has benefited from the powerful features learnt by deep neural networks, and handcrafted features specialized for abnormality detectors. However, these approaches with large complexity still have limitations in handling long term sequential data (e.g., videos), and their learnt features do not thoroughly capture useful information. Recurrent Neural Networks (RNNs) have been shown to be capable of robustly dealing with temporal data in long term sequences. In this paper, we propose a novel version of Gated Recurrent Unit (GRU), called Single Tunnelled GRU for abnormality detection. Particularly, the Single Tunnelled GRU discards the heavy weighted reset gate from GRU cells that overlooks the importance of past content by only favouring current input to obtain an optimized single gated cell model. Moreover, we substitute the hyperbolic tangent activation in standard GRUs with sigmoid activation, as the former suffers from performance loss in deeper networks. Empirical results show that our proposed optimized GRU model outperforms standard GRU and Long Short Term Memory (LSTM) networks on most metrics for detection and generalization tasks on CUHK Avenue and UCSD datasets. The model is also computationally efficient with reduced training and testing time over standard RNNs.

REPORT: NON BINARY SYNAPTIC ACTIVITY IN CORTEX
Creators: name: ISABEL DELGADO-RUZ
Publisher: name: figshare
Year: 2021
Subjects: Neuroscience

description: Traditionally, a binary view of neuronal activity has been adopted when studying cortical networks. This simplification is adequate in most situations for a general understanding of how computations and information transmition is done. Through binary representation we have learned how information is transmitted in the brain and how stimuli is represented by population brain activity (Among many valuable papers: [72], [14], [40], [68], [8], [33], [63]. See [48] for a recent review). However, increasing evidence shows that binary representation discards relevant information used by downstream neurons. In this paper we show how non binary synaptic activity is visible on different aspects of the full waveforms: pre-synaptic waveform presents consistent variations which many times do not occur on channels with the smallest amplitudes, in agreement with studies of synaptic integration (Along with many studies: [62], [18], [31], [55], [73], [59], [34]); But more importantly the shape of pre-synaptic waveform influences synaptic efficiency (number of induced post-synaptic spikes) and post-synaptic waveform. Providing evidence that spiking activity visible using HDEA is far more information rich than expected from binary representation, showing waveform variability influenced by activity of hidden nodes or sub-networks. Using n-bit words to spatio-temporal responses representing the different patterns of activation within neuron’s processes during the Action Potential, is more sensible than 1/0 outputs used on standard spike detection/sorting and clustering even on the latest software developed ([20], [58], [27] and [5]).

title: Galactic Chemical Evolution Signatures in Stellar Atmospheres and Their Possible Planetary Connection
Creators: name: Nickson, Elena
Publisher: name: The Open University
Year: 2016

description: In recent years there have been many studies to determine whether there is a chemical signature in stellar atmospheres that can be linked to the presence of planets. Most of these studies have involved bulk analysis of stars to identify whether planet-hosting stars have a higher metallicity than non planet-hosting stars. These studies led to the work of Meléndez et al. [49], which identified a signature in the solar photosphere which was likely caused by the presence of planets. To further explore this theory, I obtained high-quality spectra from the ESPaDOnS spectropolarimeter at the CFHT for 10 stars with similar stellar parameters (effective temperature, surface gravity, microturbulence velocity and metallicity). I performed a differential abundance analysis on the planet-hosting star 61 Vir against 9 comparison stars. This analysis indicated that there is no planetary signature present in 61 Vir but instead, that there is a signature observed when performing the same analysis on an individual star basis, which is observable with age. I determined the relative ages of the stars and then perform a differential abundance analysis of 9 stars using a younger tenth star as reference. From this I found likely evidence of galactic chemical evolution in the stellar atmospheres.

description: World Health Organisation (WHO) report stated that “Tobacco is the single most preventable cause of death in the world today. By 2030, the death toll will exceed eight million a year” (WHO, 2008). The carcinogens in tobacco can directly alter the genetic code, or their constituent metabolites can affect various pathways and genes (Anand, 2008). Our aim is to identify tobacco-derived metabolites, that are consumed during smoking and by the use of smokeless tobacco, that are playing a major role in the initiation and progression of various cancer types to provide a novel insight into tobacco mediated cancer.

description: In this paper, we examine the viability of inflation models with a spectator axion field coupled to both gravitational and SU(2) gauge fields via Chern-Simons couplings. Requiring phenomenological success of the axion-SU(2) sector constrains the coupling strength of the gravitational Chern-Simons term. We find that the impact of this term on the production and propagation of gravitational waves can be as large as fifty percent enhancement for the helicity that is not sourced by the gauge field, if the cut-off scale is as low as $Λ$ = 20H. The effect becomes smaller for a larger value of $Λ$, while the impact on the helicity sourced by the gauge field is negligible regardless of $Λ$.

description: This study examines whether the audit quality of Big 5 auditors declined after 1995. A decline in audit quality is measured by whether there is greater accruals-based earnings management, lower proportion of audit qualifications and lower pricing of discretionary accruals over the period 1991-2000. Using a sample of more than 4,500 clients of Big 5 auditors for the same period, we find that for the average client, the absolute value of discretionary accruals scaled by total assets is significantly greater for the years 1996-2000 compared to 1991-1995. We also find an increase in the percentage of unqualified audit reports and a decline in the pricing of discretionary accruals over the same period. Our results (including an overall year by year analysis) suggest a decline in Big 5 audit quality over the sample period.

Using research and material developed by our colleagues in previous years, as well as inputs from primary source student surveys and interviews with UBCFSP partners, we found current levels of campus composting participation to be low. Also, the effectiveness of current marketing and educational tools were poor. Following analysis of the data collected, we derived several recommendations for the various stakeholders within the food system; prepared updated marketing materials with attention to the theories of social marketing in order to increase composting awareness on campus; outlined a budget for the proposed campus-wide marketing campaign, which will coincide with the introduction of additional compost bins on campus; and discussed the linkages between the UBC food system and that of the global community.

description: Video-rate super-resolution imaging through biological tissue can visualize and track biomolecule interplays and transportations inside cellular organisms. Structured illumination microscopy allows for wide-field super resolution observation of biological samples but is limited by the strong absorption and scattering of light by biological tissues, which degrades its imaging resolution. Here we report a photon upconversion scheme using lanthanide-doped nanoparticles for wide-field super-resolution imaging through the biological transparent window, featured by near-infrared and low-irradiance nonlinear structured illumination. We demonstrate that the 976 nm excitation and 800 nm up-converted emission can mitigate the aberration. We found that the nonlinear response of upconversion emissions from single nanoparticles can effectively generate the required high spatial frequency components in Fourier domain. These strategies lead to a new modality in microscopy with a resolution of 130 nm, 1/7th of the excitation wavelength, and a frame rate of 1 fps.

Jansky Very Large Array (JVLA) observations of the massive infrared dark cloud NGC 6334S (also known as IRDC G350.56+0.44), located at the southwestern end of the NGC 6334 molecular cloud complex. The H$^{13}$CO$^{+}$ and the NH$_{2}$D lines covered by the ALMA observations at a $\sim$3$^{\prime\prime}$ angular resolution ($\sim$0.02 pc) reveal that the spatially unresolved non-thermal motions are predominantly subsonic and transonic, a condition analogous to that found in low-mass star-forming molecular clouds. The observed supersonic non-thermal velocity dispersions in massive star forming regions, often reported in the literature, might be significantly biased by poor spatial resolutions that broaden the observed line widths due to unresolved motions within the telescope beam. Our 3~mm continuum image resolves 49 dense cores, whose masses range from 0.17 to 14 $M_{\odot}$. The majority of them are resolved with multiple velocity components. Our analyses of these gas velocity components find an anti-correlation between the gas mass and the virial parameter. This implies that the more massive structures tend to be more gravitationally unstable. Finally, we find that the external pressure in the NGC 6334S cloud is important in confining these dense structures, and may play a role in the formation of dense cores, and subsequently, the embedded young stars.

description: Polyphonic sound event detection and direction-of-arrival estimation require different input features from audio signals. While sound event detection mainly relies on time-frequency patterns, direction-of-arrival estimation relies on magnitude or phase differences between microphones. Previous approaches use the same input features for sound event detection and direction-of-arrival estimation, and train the two tasks jointly or in a two-stage transfer-learning manner. We propose a two-step approach that decouples the learning of the sound event detection and directional-of-arrival estimation systems. In the first step, we detect the sound events and estimate the directions-of-arrival separately to optimize the performance of each system. In the second step, we train a deep neural network to match the two output sequences of the event detector and the direction-of-arrival estimator. This modular and hierarchical approach allows the flexibility in the system design, and increase the performance of the whole sound event localization and detection system. The experimental results using the DCASE 2019 sound event localization and detection dataset show an improved performance compared to the previous state-of-the-art solutions.

How do auditors view managers' disclosure strategy? The effect of earnings and guidance on audit fees
Creators: name: Krishnan, Gopal V.
name: Pevzner, Mikhail
name: Sengupta, Partha
Publisher: name: American University
Year: 2023

description: This paper examines whether firms' earnings forecasting policy is associated with their audit fees. We find that firms that are more likely to issue earnings forecasts, and those that issue a greater number of earnings forecasts in a particular year, pay higher audit fees. Furthermore, we find that firms that make more precise forecasts also face higher audit fees. Finally, among the forecasting firms, we find some evidence that audit fees are higher when management earning forecasts are more optimistically biased. These results are consistent with the argument that auditors view clients that make earnings forecasts to be associated with a greater risk of earnings management and litigation. These results highlight a potential cost of this particular form of voluntary disclosures.

These conditions arise from a simple ``Principle of Perturbative Agreement'': For interaction Lagrangians $L_1$ that are such that the interacting field theory can be constructed exactly--as occurs when $L_1$ is a ``pure divergence'' or when $L_1$ is at most quadratic in the field and contains no more than two derivatives--then time-ordered products must be defined so that the perturbative solution for interacting fields obtained from the Bogoliubov formula agrees with the exact solution. The conditions derived from this principle include a version of the Leibniz rule (or ``action Ward identity'') and a condition on time-ordered products that contain a factor of the free field $ϕ$ or the free stress-energy tensor $T_{ab}$. The main results of our paper are (1) a proof that in spacetime dimensions greater than 2, our new conditions can be consistently imposed in addition to our previously considered conditions and (2) a proof that, if they are imposed, then for {\em any} polynomial interaction Lagrangian $L_1$ (with no restriction on the number of derivatives appearing in $L_1$), the stress-energy tensor $Θ_{ab}$ of the interacting theory will be conserved. Our work thereby establishes (in the context of perturbation theory) the conservation of stress-energy for an arbitrary interacting scalar field in curved spacetimes of dimension greater than 2. Our approach requires us to view time-ordered products as maps taking classical field expressions into the quantum field algebra rather than as maps taking Wick polynomials of the quantum field into the quantum field algebra.

description: This paper examines whether firms' earnings forecasting policy is associated with their audit fees. We find that firms that are more likely to issue earnings forecasts, and those that issue a greater number of earnings forecasts in a particular year, pay higher audit fees. Furthermore, we find that firms that make more precise forecasts also face higher audit fees. Finally, among the forecasting firms, we find some evidence that audit fees are higher when management earning forecasts are more optimistically biased. These results are consistent with the argument that auditors view clients that make earnings forecasts to be associated with a greater risk of earnings management and litigation. These results highlight a potential cost of this particular form of voluntary disclosures.

Research Application Management: Adapting research outputs for more real-world users

description: Academia encourages novel knowledge creation, while investment in maintenance, interconnectivity and reusability beyond the original field is typically deprioritised. To address this incentive gap, last year we created the role of the Research Application Manager (RAM) within the Tools, Practices and Systems (TPS) programme at The Alan Turing Institute. RAMs are a new addition to the Team Science family, working closely with Community Managers to embed stakeholder needs into the research output creation process, and contributing to the TPS programme’s mission to create more reproducible, accessible, and interoperable research. RAMs work to ensure that research outputs are adopted by a more diverse set of stakeholders for real-world use cases. Based on engagements during the RAM team’s first year, we will present case studies on our learnings from specific projects and at departmental and organisational levels: Engagement with local government and the general public to co-create solutions to address climate change and transportation safety Multi-stakeholder collaboration for information governance best practices as part of Trusted Research Environment infrastructure Connecting researchers with academia and industry stakeholders The RAM role is a new concept within academia, and we are eager to engage in conversations about the role and similar roles with the “Big Team Science” audience. This includes exploring how activities like enabling stakeholder engagement and cross-disciplinary collaboration fit within the open science umbrella, best practices for collaboration with other research infrastructure roles, and pathways for scaling the RAM role to other research organisations.

description: By using the public data from Jan. 20 to Feb. 11, 2020, we perform data-driven analysis and forecasting on the COVID-19 epidemic in mainland China, especially Hubei province. Our results show that the turning points of the daily infections are predicted to be Feb. 6 and Feb. 1, 2020, for Hubei and China other than Hubei, respectively. The epidemic in China is predicted to end up after Mar. 10, 2020, and the number of the total infections are predicted to be 51600. The data trends reveal that quick and active strategies taken by China to reduce human exposure have already had a good impact on the control of the epidemic.

title: Extra-Solar Planetary Atmospheres and Interior Structure: Implications for Observational Signatures
Creators: name: Bending, Victoria Louise
Publisher: name: The Open University

description: Hot Jupiter exoplanets are a previously unknown and fascinating field of study. Models of planet formation based only around the Solar System did not predict their existence, occupying as they do the orbital region less than 0.1 AU from their parent stars. Believed to be tidally locked, always presenting the same face to the star, these gas giants are bathed in intense irradiation, and inhabit a regime alien to anything known in the Solar System. As exoplanetary surveys discover an increasing number of planets, the ubiquity of hot Jupiters in the galaxy continues to be confirmed. Both the evolution and the atmospheric dynamics of these unusual planets are natural focuses of study. However, most authors have historically concentrated on one or the other of these two lines of enquiry, although both are linked. In the case of gas giants in particular, which have no true ground or otherwise easily defined surface layer, the two regimes blend towards the outer layers of the planet. This convergence renders the possibility of model overlap ever more relevant, a possibility that is here studied, both independently and together, ultimately continuing to the modelling of the specific known exoplanets HD 209458b, HD 189733b, and WASP-7b. It is found that, while it is reasonable for interior evolution model results to be used to provide boundary conditions and atmospheric characteristics for the purposes of three-dimensional atmospheric modelling, the reverse is a much more difficult proposition, providing few truly relevant constraints. Observational characteristics are also predicted, with cyclic variability found in the case of HD 209458b, a more permanently variable state in the case of HD 189733b, and very little longitudinal temperature variation for the calmer atmosphere of WASP-7b.

description: We study the excitonic insulating (EI) phase in the two-band Hubbard models on the Penrose tiling. Performing the real-space mean-field calculations systematically, we obtain the ground state phase diagrams for the vertex and center models. We find that, in some regimes, the stable EI phase is induced by small interband interactions. We argue that this originates from the electron-hole pairing for the completely or nearly degenerate states, which are characteristic of the Penrose tiling. We also study spatial distribution of the order parameter, mapping it to the perpendicular space.

Glucose availability but not changes in pancreatic hormones sensitizes hepatic AMPK activity during nutritional transition in rodents

description: The cellular energy sensor AMP-activated protein kinase (AMPK) is a metabolic regulator that mediates adaptation to nutritional variations in order to maintain a proper energy balance in cells. We show here that suckling-weaning and fasting-refeeding transitions in rodents are associated with changes in AMPK activation and the cellular energy state in the liver. These nutritional transitions were characterized by a metabolic switch from lipid to glucose utilization, orchestrated by modifications in glucose levels and the glucagon:insulin ratio in the bloodstream. We therefore investigated the respective roles of glucose and pancreatic hormones on AMPK activation in mouse primary hepatocytes. We found that glucose starvation transiently activates AMPK, whereas changes in glucagon and insulin levels had no impact on AMPK. Challenge of hepatocytes with metformin-induced metabolic stress strengthened both AMPK activation and cellular energy depletion limited-glucose conditions, whereas neither glucagon nor insulin altered AMPK activation. Although both insulin and glucagon induced AMPK$α$ phosphorylation at its Ser-485/491 residue, they did not affect its activity. Finally, the decrease in cellular ATP levels in response to an energy stress was additionally exacerbated under fasting conditions and by AMPK deficiency in hepatocytes, revealing metabolic inflexibility and emphasizing the importance of AMPK for maintaining hepatic energy charge. Our results suggest that nutritional changes (i.e. glucose availability), rather than the related hormonal changes (i.e. the glucagon:insulin ratio), sensitize AMPK activation to the energetic stress induced by the dietary transition during fasting. This effect is critical for preserving the cellular energy state in the liver.
