description: In bilayer CrI3, experimental and theoretical studies suggest that the magnetic order is closely related to the layer staking configuration. In this work, we study the effect of dynamical lattice distortions, induced by non-linear phonon coupling, in the magnetic order of the bilayer system. We use density functional theory to determine the phonon properties and group theory to obtain the allowed phonon-phonon interactions. We find that the bilayer structure possesses low-frequency Raman modes that can be non-linearly activated upon the coherent photo-excitation of a suitable infrared phonon mode. This transient lattice modification, in turn, inverts the sign of the interlayer spin interaction for parameters accessible in experiments, indicating a low-frequency light-induced antiferromagnet-to-ferromagnet transition.

description: This paper offers a conceptual analysis of the unaccounted-for cost of owning and operating used machines from an operational, financial and market perspective. It is based on input from experts and a literature review. In the scientific literature, assessing the operating cost of used machines in forest operations is typically based on standard cost assessment methods using costing/pricing input from similar unused machines. This is the case since there are usually no historical data for observed used machines available to analyze. This substitute analysis is problematic to many used and depreciated machines owners. The changing trends in forest technology attest that old machinery do not hold to the same input cost data variables or values of new machines. In fact, they belong to two rather competing different markets: (used vs. new equipment markets). With the technological, market and machinery regulations and dynamic changes, the substitute cost analysis is not representative. Better data is required to understand the cost of owning and operating used machines and the justification is the focal point of this paper. The outcome of the expert and literature analysis in this paper demonstrates that a broader understanding of the cost of a used machine is required and doable. A proposed understanding integrates the machine availability (performance), cost factors (financial) and market evaluation (price), in isolation (single piece of machine) as well as in a fleet, to assess a used machine ownership cost. The study is intended to offer forest machine operators, owners, scientists, and practitioners a proposed new approach to value used machines and further investigations and data inputs required to make used machines costing methods more relevant.

description: Non-technical summary Conserving tropical forests has many benefits, from protecting biodiversity, sustaining indigenous and local communities, and safeguarding climate. To achieve the ambitious climate goals of the Paris Agreement, forest protection is essential. Yet deforestation continues to diminish the world's forests. Halting this trend is the objective of the international framework for Reducing Emissions from Deforestation and forest Degradation (REDD+). While previous studies have demonstrated the contribution of tropical forests to mitigate climate change, here we show that tropical forest protection can 'flatten the curve' of the costs of transition to climate stability, estimating tens of trillions of dollars in policy cost savings. Technical summary The pledges made by parties under the Paris Agreement are insufficient to limit global warming to well below 2 °C relative to pre-industrial levels. We use a global climate-economic model to quantify the economic benefits from rapidly deploying programs for reducing emissions from deforestation and forest degradation and increased reforestation (REDD+) given current delays in the implementation of climate policies around the world. REDD+ has been shown to have substantial greenhouse gas emissions mitigation potential in the fight against climate change and can thus play a critical role in closing the emissions gap, thereby enabling the achievement of more ambitious climate targets. Under our principal scenario, we estimate that REDD+ can contribute up to US$36 trillion in net policy cost savings by mitigating the adjustment costs of reaching a greenhouse gas emissions trajectory consistent with ambitious global climate stabilization goals. Investment in REDD+ has a high benefit-cost ratio; one dollar invested in REDD+ yields about US$5.4 in net policy cost savings. Realizing the full estimated potential for REDD+ reduces the risk-adjusted carbon price in 2030 by US$45/tCO2.

description: This paper suggests a framework for the learning of discretizations of expensive forward models in Bayesian inverse problems. The main idea is to incorporate the parameters governing the discretization as part of the unknown to be estimated within the Bayesian machinery. We numerically show that in a variety of inverse problems arising in mechanical engineering, signal processing and the geosciences, the observations contain useful information to guide the choice of discretization.
High-dimensional Neural Feature Design for Layer-wise Reduction of Training Cost

description: We design a ReLU-based multilayer neural network by mapping the feature vectors to a higher dimensional space in every layer. We design the weight matrices in every layer to ensure a reduction of the training cost as the number of layers increases. Linear projection to the target in the higher dimensional space leads to a lower training cost if a convex cost is minimized. An $\ell_2$-norm convex constraint is used in the minimization to reduce the generalization error and avoid overfitting. The regularization hyperparameters of the network are derived analytically to guarantee a monotonic decrement of the training cost, and therefore, it eliminates the need for cross-validation to find the regularization hyperparameter in each layer. We show that the proposed architecture is norm-preserving and provides an invertible feature vector, and therefore, can be used to reduce the training cost of any other learning method which employs linear projection to estimate the target.

description: The subluminous red nova (SLRN) ZTF SLRN-2020 is the most compelling direct detection of a planet being consumed by its host star, a scenario known as a planetary engulfment event. We present JWST spectroscopy of ZTF SLRN-2020 taken +830 d after its optical emission peak using the NIRSpec fixed-slit $3-5$ $μ$m high-resolution grating and the MIRI $5-12$ $μ$m low-resolution spectrometer. NIRSpec reveals the $^{12}$CO fundamental band ($ν=1-0$) in emission at $\sim4.7$ $μ$m, Brackett-$α$ emission, and the potential detection of PH$_3$ in emission at $\sim4.3$ $μ$m. The JWST spectra are consistent with the claim that ZTF SLRN-2020 arose from a planetary engulfment event. We utilize DUSTY to model the late-time $\sim1-12$ $μ$m spectral energy distribution (SED) of ZTF SLRN-2020, where the best-fit parameters indicate the presence of warm, $720^{+80}_{-50}$ K, circumstellar dust with a total dust mass of Log$\left(\frac{M_\mathrm{d}}{\mathrm{M}_\odot}\right)=-10.61^{+0.08}_{-0.16}$ M$_\odot$. We also fit a DUSTY model to archival photometry taken +320 d after peak that suggested the presence of a cooler, T$_\mathrm{d}=280^{+450}_{-20}$ K, and more massive, Log$\left(\frac{M_\mathrm{d}}{\mathrm{M}_\odot}\right)=-5.89^{+0.29}_{-3.21}$, circumstellar dust component. Assuming the cool component originates from the ZTF SLRN-2020 ejecta, we interpret the warm component as fallback from the ejecta. From the late-time SED model we measure a luminosity of L$_* = 0.29^{+0.03}_{-0.06}$ L$_\odot$ for the remnant host star, which is consistent with a $\sim0.7$ M$_\odot$ K-type star that should not yet have evolved off the main sequence. If ZTF SLRN-2020 was not triggered by stellar evolution, we suggest that the planetary engulfment was due to orbital decay from tidal interactions between the planet and the host star.

description: The International Health Regulations (IHR) continue to be one of the driving forces behind health security preparedness in Sub-Saharan Africa (SSA). While progress has been made, there is still much work to do for these nations to meet IHR standards. Policy implementation and development activities tend to employ “best practices” with little emphasis on the institutional factors (e.g., cultural, social, and political) that would sustain them. This article will discuss the results of a mixed-methods study on relationships between state capacity proxies and global health security preparedness capacities. The conclusion being that health strengthening activities for preparedness should consider political, social, and economic context to enhance sustainability.

description: The study purpose is to comprehensively measure landlord-related forced moves (inclusive of, but not restricted to, legal eviction), and to examine whether landlord-related forced moves is associated with HIV risk. Baseline survey data was collected between 2017 and 2018 among 360 low-income participants in New Haven, Connecticut. We used multivariable logistic regression analyses to examine associations between landlord-related forced moves and HIV sexual risk outcomes. Seventy seven out of three hundred and sixty participants reported a landlord-related forced move in the past 2 years, of whom 19% reported formal eviction, 56% reported informal eviction and 25% reported both. Landlord-related forced moves were associated with higher odds of unprotected sex (AOR 1.98), concurrent sex (AOR 1.94), selling sex for money or drugs (AOR 3.28), exchange of sex for a place to live (AOR 3.29), and an HIV sexual risk composite (ARR 1.46) (p <.05 for all). We found robust associations between landlord-related forced moves and HIV sexual risk. Findings suggest that the social and economic consequences of landlord-related forced moves may impact sexual vulnerability.

description: Event cameras are paradigm-shifting novel sensors that report asynchronous, per-pixel brightness changes called 'events' with unparalleled low latency. This makes them ideal for high speed, high dynamic range scenes where conventional cameras would fail. Recent work has demonstrated impressive results using Convolutional Neural Networks (CNNs) for video reconstruction and optic flow with events. We present strategies for improving training data for event based CNNs that result in 20-40% boost in performance of existing state-of-the-art (SOTA) video reconstruction networks retrained with our method, and up to 15% for optic flow networks. A challenge in evaluating event based video reconstruction is lack of quality ground truth images in existing datasets. To address this, we present a new High Quality Frames (HQF) dataset, containing events and ground truth frames from a DAVIS240C that are well-exposed and minimally motion-blurred. We evaluate our method on HQF + several existing major event camera datasets.

description: Comets contain primitive material leftover from the formation of the Solar System, making studies of their composition important for understanding the formation of volatile material in the early Solar System. This includes organic molecules, which, for the purpose of this review, we define as compounds with C–H and/or C–C bonds. In this review, we discuss the history and recent breakthroughs of the study of organic matter in comets, from simple organic molecules and photodissociation fragments to large macromolecular structures. We summarize results both from Earth-based studies as well as spacecraft missions to comets, highlighted by the Rosetta mission, which orbited comet 67P/Churyumov–Gerasimenko for two years, providing unprecedented insights into the nature of comets. We conclude with future prospects for the study of organic matter in comets.

description: A Heegaard splitting of a closed, orientable three-manifold satisfies the disjoint curve property if the splitting surface contains an essential simple closed curve and each handlebody contains an essential disk disjoint from this curve [Thompson, 1999]. A splitting is full if it does not have the disjoint curve property. This paper shows that in a closed, orientable three-manifold all splittings of sufficiently large genus have the disjoint curve property. From this and a solution to the generalized Waldhausen conjecture it would follow that any closed, orientable three manifold contains only finitely many full splittings.

In deriving the non-decay probability of the system, we argue that the appropriate technique to use is the less known method of scattering states. This method is illustrated through two examples, namely, a moving delta-potential and a moving barrier potential. For expanding potentials, one finds that a small but finite non-decay probability persists at large times. Generalization to scaling potentials of arbitrary shape is briefly indicated.

description: Comets contain primitive material leftover from the formation of the Solar System, making studies of their composition important for understanding the formation of volatile material in the early Solar System. This includes organic molecules, which, for the purpose of this review, we define as compounds with C–H and/or C–C bonds. In this review, we discuss the history and recent breakthroughs of the study of organic matter in comets, from simple organic molecules and photodissociation fragments to large macromolecular structures. We summarize results both from Earth-based studies as well as spacecraft missions to comets, highlighted by the Rosetta mission, which orbited comet 67P/Churyumov–Gerasimenko for two years, providing unprecedented insights into the nature of comets. We conclude with future prospects for the study of organic matter in comets.

description: We investigate here the local versus global visibility of a space-time singularity formed due to the gravitational collapse of a spherically symmetric dust cloud having a non-zero velocity function. The conditions are investigated that ensure the global visibility of the singularity, in the sense that the outgoing null geodesics leave the boundary of the matter cloud in the future, whereas, in the past, these terminate at the singularity. Explicit examples of this effect are constructed. We require that this must be a strong curvature singularity in the sense of Tipler, to ensure the physical significance of the scenario considered. This may act as a counterexample to the weak cosmic censorship hypothesis.

Stabilizing quantum metastable states in a time-periodic potential

Year: 2004

description: Metastability of a particle trapped in a well with a time-periodically oscillating barrier is studied in the Floquet formalism. It is shown that the oscillating barrier causes the system to decay faster in general. However, avoided crossings of metastable states can occur with the less stable states crossing over to the more stable ones. If in the static well there exists a bound state, then it is possible to stabilize a metastable state by adiabatically increasing the oscillating frequency of the barrier so that the unstable state eventually cross-over to the stable bound state. It is also found that increasing the amplitude of the oscillating field may change a direct crossing of states into an avoided one.

Purpose in Life as a Moderator of the Relationship Between Depression and Chronic Conditions
Creators: name: Cox, Diana J.
Publisher: name: American University
Year: 2023

description: Depression is an important risk factor for many chronic health conditions, especially cardiovascular disease. Depression can affect the biological pathways that increase disease risk, and it can worsen the symptoms of chronic disease by decreasing self-care behaviors. However, just as it is important to identify risk factors of chronic illnesses, it is equally as important to identify protective factors. One potential protective factor may be sense of purpose in life, or the idea that life has meaning and direction. Purpose in life has been linked to lower incidence of certain chronic diseases and has also been negatively correlated with depressive symptoms. A sense of purpose in life could buffer the effect of depression by serving as a motivator for health-promoting behaviors. This study investigated whether high sense of purpose in life influences the long-term associations between depression, number of chronic illnesses, and cardiovascular risk. Participants were adults who participated in a national, longitudinal study called Midlife Development in the United States (MIDUS). Results indicated that purpose in life did not moderate the relationship between depression and number of chronic health conditions, depression and number of cardiovascular diagnoses, or depression and subjective heart attack risk at either MIDUS timepoint. The findings from this study suggest that purpose in life may not be the appropriate moderator for these relationships, but other variables of psychological well-being, such as autonomy, may be better suited to influence the association of depression and chronic disease.

description: Monocular 3D human pose and shape estimation is challenging due to the many degrees of freedom of the human body and thedifficulty to acquire training data for large-scale supervised learning in complex visual scenes. In this paper we present practical semi-supervised and self-supervised models that support training and good generalization in real-world images and video. Our formulation is based on kinematic latent normalizing flow representations and dynamics, as well as differentiable, semantic body part alignment loss functions that support self-supervised learning. In extensive experiments using 3D motion capture datasets like CMU, Human3.6M, 3DPW, or AMASS, as well as image repositories like COCO, we show that the proposed methods outperform the state of the art, supporting the practical construction of an accurate family of models based on large-scale training with diverse and incompletely labeled image and video data.

description: UBC Farm stakeholders are investigating the potential of biofuel production for the purpose of energy generation and greenhouse gas reduction. This paper examines a triple bottom line assessment for the addition of Giant Miscanthus (Miscanthus x giganteus) biofuel to UBC farm margins and hedgerows. The methodology behind choosing Miscanthus rather than Alder or Willow is discussed as well as background information for this perennial plant. An annual yield of 15t/ha was estimated for an overall available area of 1ha. A cost analysis determined an establishment cost of $650USD for a 1ha plot of Giant Miscanthus and a literature study allowed for estimating operating costs to be roughly $30/t DM. A sensitivity analysis determined annual net project economics of $274-823. To add value for the farm and campus community, insight is given into the social implications of planting and harvesting biofuels. It was determined that many relationships can be gained and nurtured through collaborations with fellow researchers and communities including native groups and prospective biofuel growers. It is expected that educational opportunities will arise from the plantations in both agroforestry and biofuel research as well as both student body and community volunteer opportunities. Biofuel crops on the farm are also expected to give UBC a stronger overall image as an environmental leader in GHG reduction. In investigating the environmental implications of growing a biofuel crop at the farm, understanding the carbon footprint and green energy offset as well as agricultural and wildlife impacts is necessary. The carbon savings compared to the current acquisition process is approximately 140 kg and is further reduced through human labor harvest by ~40 kg. The estimated green energy output annually is 62.5MWh which equates to 225GJ. By planting Miscanthus hedgerows animal corridors are created as well as habitat for pollinators. Furthermore, soil erosion is prevented and wind shelter for neighboring crops is provided. Although the environmental and economic considerations are important, the social implications were paramount in coming to the conclusion that this project should proceed. The project is revenue generating but relatively insignificant.
